Abstract
The present invention relates to a fixing and spacing structure for a liquid level standard position measuring device, which is used for fixing and spacing a sensing rod and a liquid level standard position sensing floating body of the liquid level standard position measuring device. The present invention comprises a supporting body, spacing bodies and through holes, wherein the spacing bodies are fixedly connected with the supporting body at intervals; the through holes are formed in the spacing bodies so that the sensing rod of the liquid level standard position measuring device can penetrate into the through holes of the present invention, and the liquid level standard position sensing floating body is glidingly arranged on the sensing rod and is in a floating spaced state between the two spacing bodies. The fixing and spacing structure of the present invention can fix the sensing rod of the liquid level standard position measuring device to limit the distance for the liquid level standard position sensing floating body to float on the sensing rod. Thus, a screw can be prevented from being tightly fixed to the sensing rod so as to destroy the sensing rod.
Description
Technical field
The present invention is the fixing and limiting structure of the accurate position of a kind of liquid levels measuring equipment, refers to the fixing and limiting structure as the accurate position of fixing and spacing liquid levels measuring equipment especially.
Background technology
See also shown in Figure 1, machine such as need main system supply fluid, to keep the machine normal operation, this machine is provided with a liquid temporary tank 10a usually, to store the liquid that main system is supplied, therefore the burden that main system is carried out supply fluid always can be alleviated, moreover main system generation problem can be prevented and situation that can not supply fluid, so can be by liquid temporary tank 10a supplying machine liquid to keep the machine normal operation.So the liquid number in this liquid temporary tank 41a need utilize the accurate position of a liquid levels measuring equipment 20a to measure according to this, and then main system is replenished or suspend supply fluid to liquid temporary tank 10a.
See also Fig. 2, shown in Figure 3, the accurate position of this liquid levels measuring equipment 20a comprises sensing bar 21a and the accurate position of liquid level sensing buoyancy aid 25a, wherein the accurate position of a liquid level sensing buoyancy aid 25a is arranged on this sensing bar 21a and slides thereon, and this sensing bar 21a comprises a hollow bar 22a and is several magnetic-inductive devices 23a that longitudinally is provided with and is electrically connected in this hollow bar 22a, has permanent magnet 26a in the sensing buoyancy aid 25a of the accurate position of this liquid level, therefore when the accurate position of a liquid level sensing buoyancy aid 25a is slidedly arranged on this sensing bar 21a, and the accurate position of this liquid level sensing buoyancy aid 20a is floated on liquid level, can respond to permanent magnet 26a on the sensing buoyancy aid 25a of the accurate position of this liquid level with turning circuit by this magnetic-inductive device 23a, so understand the accurate position of liquid level of this liquid, know the liquid levels height in this liquid temporary tank 10a according to this with the height and position that utilizes magnetic-inductive device 23a to be positioned at this hollow bar 22a.
Therefore, having four magnetic-inductive device 23a in the sensing bar 21a of this equipment is arranged in it, the accurate position of too high to orient, high and low and low excessively liquid levels, and utilize screw 30a locking five location ring body 31a to be locked on the sensing bar 21a, and make the accurate position of four liquid levels sensing buoyancy aid 25a be arranged in sensing bar 21a and go up and float between the ring body 31a of location, so float on sensing bar 21a and go up distance with the accurate position of qualification liquid level sensing buoyancy aid 25a.
But, utilizing this location ring body 31a to be locked in sensing bar 21a goes up to limit the accurate position of a liquid level sensing buoyancy aid 25a and floats on sensing bar 21a to go up distance non-be the mode of the best, because this screw 30a is pressed against on the sensing bar 21a, lock location ring body 31a thereon with this, but, lead or magnetic-inductive device 23a that this sensing bar 21a damage and liquid are flowed in the hollow body 22a damage, cause electric signal can't normal delivery to control system of machine so that can't normal operation; Perhaps lock pine and cause failing to produce spacing function too.
Thus, the inventor is according to this shortcoming and according to being engaged in the correlation experience that manufactures a product for many years, and concentrated the observation and research is to concentrate on studies and cooperate the utilization of scientific principle, and proposes a kind of reasonable in design and effectively improve the present invention of this shortcoming.
Summary of the invention
The object of the present invention is to provide the fixing and limiting structure of the accurate position of a kind of liquid levels measuring equipment,, so can avoid screw to be anchored on sensing bar so that destroy sensing bar with the sensing bar of the accurate position of fixing liquid levels measuring equipment and limit the distance that the accurate position of described liquid level sensing buoyancy aid floats on this sensing bar by fixing and limiting structure.
For achieving the above object, the fixing and limiting structure of the accurate position of liquid levels of the present invention measuring equipment, in order to the sensing bar and the accurate position of the liquid level sensing buoyancy aid of the accurate position of fixing spacing this liquid levels measuring equipment, it comprises at least one supporter, some interval bodies, some perforation; Wherein, described some interval bodies are fixed on the described supporter compartment of terrain respectively; Some perforation are formed at respectively on the described interval body, so that described sensing bar is placed through in this perforation, and make the accurate position of a described liquid level sensing buoyancy aid be slidedly arranged on the sensing bar and float to be limited between two interval bodies.
Described supporter is the body of rod, and described interval body is fixed on this body of rod.
Described interval body is a plate body, to limit the accurate position of described liquid level sensing buoyancy aid in this sensing barred body distance that fluctuates.
Fixing and limiting structure of the present invention can have several supporters, and described interval body is fixed in this supporter at interval to form support body.
In order to make the auditor can further understand feature of the present invention and technology contents, see also following relevant detailed description of the present invention and accompanying drawing, yet appended icon only provides reference and explanation usefulness, is not to be used for the present invention is limited.
