Description
TECHNICAL FIELD
[0001] The present disclosure relates to the technical field of sewage monitoring equipment, in particular to a liquid level detection mechanism for a sewage pool and a sewage monitoring equipment. BACKGROUND
[0002] At present, in the sewage pool liquid level detection work, due to the non-contact detection characteristics of the ultrasonic liquid level meter, the liquid level of the sewage in the sewage pool can be effectively detected, and the sundries in the sewage pool can be found and cleaned in time, which can greatly avoid the blockage of the sewage pool by the sundries in the sewage. However, due to the harsh working environment of the sewage pool, the sundries (such as plastic bags or weeds) floating on the surface of the sewage are easy to attach or entangle the liquid level detection probe of the ultrasonic liquid level meter during the process of discharging the sewage into the sewage pool, so that the signal of the ultrasonic liquid level meter is blocked, thereby affecting the accurate detection of the liquid level of the sewage liquid surface.
[0003] At the same time, the ultrasonic liquid level meter is generally installed on a metal support, and the metal support is fixedly installed on the sewage pool. In the face of extreme weather such as rainy days, the metal support is easy to rust and corrode, which causes some debris of the metal support to adhere to or contaminate the liquid level detection probe of the ultrasonic liquid level meter, thereby causing the problem of inaccurate detection of the liquid level of the sewage liquid surface.

[0018] A sewage monitoring device comprises the liquid level detection mechanism for the sewage tank according to any one of the above embodiments.
[0019] Compared with the prior art, the present disclosure has at least the following advantages:
[0020] 1) The liquid level detection mechanism for sewage tanks disclosed herein features a locking groove at one end of a stainless steel mounting bracket, which ensures the secure installation of the stainless steel mounting bracket in the sewage tank and guarantees the stability of the ultrasonic level gauge mounted on the stainless steel mounting bracket.

[0032] It can be understood that, due to the clamping groove 101 provided at one end of the stainless steel mounting bracket 100, the stainless steel mounting bracket 100 is firmly fixed on the sewage tank 20, and the stability of the ultrasonic liquid level meter 200 installed on the stainless steel mounting bracket 100 is ensured. In addition, the stainless steel mounting bracket 100 itself has strong corrosion resistance, and the other end of the stainless steel mounting bracket 100 is provided with the mounting containing groove 102, and the inner wall of the mounting containing groove 102 is coated with the anti-corrosion coating 400, which further enhances the corrosion resistance of the mounting containing groove 102 of the stainless steel mounting bracket 100, avoiding the adhesion or pollution of the liquid level detection probe 210 of the ultrasonic liquid level meter 200 by the debris after the rust corrosion of the metal bracket in the traditional technology, thereby improving the accuracy of the ultrasonic liquid level meter 200 in detecting the liquid level of the sewage liquid surface 30.
[0033] It can also be understood that the stainless steel mounting bracket 100 is connected with the stainless steel anti-net hanging cover 300, and since the stainless steel anti-net hanging cover 300 itself has strong corrosion resistance and covers the liquid level detection probe 210, the debris floating on the surface of the sewage is blocked by the stainless steel anti-net hanging cover 300, avoiding the debris from directly adhering or winding around the liquid level detection probe 210, and at the same time, the stainless steel anti-net hanging cover 300 itself has a through hole, which can ensure that the detection signal of the liquid level detection probe 210 is timely delivered out, thereby improving the accuracy of the ultrasonic liquid level meter 200 in detecting the liquid level of the sewage liquid surface 30.
