Description

Technical Field

[0001] The utility model relates to the technical field of liquid level gauges, in particular to a fixing device for an immersion type liquid level gauge. Background Art

[0002] The immersion level gauge is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It is made of advanced isolated diffused silicon sensitive elements or ceramic capacitor pressure sensitive sensors. It converts static pressure into electrical signals, which are then converted into standard electrical signals through temperature compensation and linear correction. It is a pressure sensor for measuring liquid level.

[0003] The Chinese patent with the patent publication number CN218381191U discloses a submersible liquid level meter, including a submersible probe body, a sealing connection sleeve is installed on the top of the submersible probe body, a connecting line is installed on the top of the submersible probe body through the sealing connection sleeve, a support plate seat is fixedly installed on the top of the side surface of the submersible probe body, and a threaded shaft head is fixedly installed in the middle of the side of the support plate seat. The above patent will have the following problems during use: when the submersible liquid level meter is used, the detection head is suspended and placed in the measured liquid. When the liquid surges, the detection head surges with the wave, which is easy to affect the measurement accuracy of the sensor at the bottom of the detection head, resulting in inaccurate liquid level measurement results. Moreover, due to the long length of the released wire, the wire is easy to shake under the action of the water flow and drive the probe to shake, so that the submersible liquid level meter is greatly affected by the surge of the water flow, and the measurement accuracy is greatly reduced.

[0022] A through hole is provided in the middle of the fixing plate 1, and a placement groove 13 for placing the level gauge joint is provided in the middle of the fixing plate 1. When the immersion level gauge is used in the field of sewage treatment, for example, in a sewage sedimentation tank, the fixing plate 1 is first fixed to the pool side by bolts, ground nails, etc. (that is, the fixing plate 1 is fixed by inserting the anchor bolts or ground nails into the mounting hole 2), and then the probe of the level gauge is lowered from the through hole in the middle of the fixing plate 1 to the corresponding moving block 7, and the probe is located between the two clamping plates 9. At this time, the two clamping plates 9 are in an open state, and the two clamping plates 9 are rotated so that the two clamping plates 9 are The plate 9 fits and clamps the probe in the arc-shaped concave surface 11 of the two clamping plates 9, and then a bolt is inserted into the threaded hole 10 to fix the clamping plates 9 and clamp the probe; then the driving motor 3 rotates in the forward direction, and drives the moving block 7 and the clamping plate 9 to drive the probe to move downward and move to the bottom of the pool. At this time, the probe is located at the bottom of the pool and is fixed by the clamping plate 9. When the liquid shakes, the clamping plate 9 and the moving block 7 can effectively ensure that the probe will not shake; on the other hand, when the probe moves to the bottom of the pool, the cable of the level meter is in a stretched and straight state, and the cable in the straight state can effectively reduce the shaking of the cable by the water flow.

The brush member 8 is hollow cylindrical and sleeved on the outer wall of the screw rod 4, and the brush portion of the brush member 8 is arranged on the inner wall of the hollow cylindrical brush member 8 and fits with the screw rod 4.

[0024] Since the precipitated impurities in the sedimentation tank will adhere to the screw rod 4 and thus affect the normal movement of the moving block 7, when the moving block 7 moves up and down, the precipitated impurities adhered to the screw rod 4 can be cleaned in advance by the brush member 8 to ensure the normal movement of the moving block 7.

[0025] Specifically, in this embodiment, a filter frame 12 adapted to the liquid level meter probe is provided at the lower end of the splint 9, and the filter frame 12 is semi-cylindrical. When the two splints 9 are fitted together, the two semi-cylindrical filter frames 12 are fitted together to form a cylindrical frame, and are sleeved outside the probe. The side and bottom surfaces of the cylindrical frame are both filter nets, and impurities are blocked outside the filter frame 12 through the filter nets to prevent impurities from flowing into the probe and affecting the measurement accuracy of the probe.
