Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, and more specifically to a Doppler sewage well pollutant alarm device. Background Art

[0002] In sewage discharge systems, abnormal flow changes are often related to abnormal discharge events, such as illegal sewage discharge or pollutant blockage in pipes. Doppler flow meters are often used to continuously monitor sewage flow. When the flow suddenly increases or decreases to abnormal levels, this may be a sign of increased pollutant emissions or pipe blockage. The use of Doppler flow meters can indirectly help identify certain pollutant-related problems, thereby assisting in the realization of alarm functions.

[0003] Chinese Patent Authorization Announcement No.: CN 216050110 U provides an easy-to-maintain Doppler flowmeter auxiliary device in a sewage pipe, which solves the problem that the water flow conditions in the sewage pipe are complex, accompanied by a considerable volume of solid impurities and waste, which are easily accumulated on the surface of the Doppler flowmeter, thereby blocking the flowmeter and affecting the accuracy of flow measurement.

[0004] In actual use of the prior art, due to the narrow space in the sewage well, the range of movement of the operator is limited, and the operation of fixing the bolts and nuts when installing the flow meter becomes difficult and laborious. Therefore, a Doppler sewage well pollutant alarm device is proposed. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a Doppler sewage well pollutant alarm device, which can squeeze the telescopic rod and the spring through the movable plate by pulling the pull rod downward and drive the insertion rod to move upward and leave the inner cavity of the mounting plate. At this time, the bracket is placed into the mounting block, and the mounting plate is inserted into the mounting block. Then the pull rod is released and the elastic force of the spring itself drives the movable plate and the insertion rod to move upward again into the mounting block and the inner cavity of the mounting plate, so that the bracket is limitedly installed on the mounting block. The installation and disassembly of the bracket can be easily achieved by pulling the pull rod to move. Compared with the traditional bolt fixing installation method, it is simpler and more convenient, and can reduce the difficulty of operators installing the bracket underground.

[0006] To solve the above problems, the utility model adopts the following technical solutions.

[0007] A Doppler sewage well pollutant alarm device comprises a sewage well and a sewage pipe, wherein the sewage pipe is arranged below the sewage well, the inner wall of the sewage well is fixedly connected with a bracket, one end of the bracket is fixedly connected with a mounting block, the inner cavity of the mounting block is provided with a mounting mechanism, and the outer surface of the mounting mechanism is provided with a protective mechanism; the mounting mechanism comprises a bracket movably connected to the inner cavity of the mounting block, the upper end of the bracket is fixedly connected with a flow meter body, the outer surface of the bracket is fixedly connected with a detection probe, both sides of the bracket are fixedly connected with mounting plates, the mounting plate and the inner cavity of the mounting block are interspersed with plug rods, the lower end of the plug rod is fixedly connected with a movable plate, the lower surface of the movable plate is fixedly connected with a telescopic rod, and the lower end of the telescopic rod is fixedly connected with a fixed plate; the protective mechanism comprises a wire pipe sleeve movably connected to one side of the bracket, and the outer surface of the wire pipe sleeve is movably connected with a pipe clamp.

[0008] Furthermore, the flow meter body and the detection probe are connected via wires and electric wires, and the wires are located inside the wire tube sleeve.

[0009] Furthermore, the pipe clamp is fixedly connected to the bracket by bolts, and the pipe clamp and the wire pipe sleeve are both made of stainless steel.

[0010] Furthermore, the mounting plate is located in the inner cavity of the mounting block, and one side of the fixing plate is fixedly connected to the bracket.

[0011] Furthermore, a spring is sleeved on the outer surface of the telescopic rod, the upper end of the spring is fixedly connected to the movable plate, and the lower end of the spring is fixedly connected to the fixed plate.

[0012] Furthermore, there are four movable plates, and one side of the four movable plates is fixedly connected to a pull rod.

[0013] Furthermore, the upper surface of the movable plate abuts against the lower surface of the mounting block.

[0014] Furthermore, the bracket is L-shaped, and the mounting block is U-shaped. Beneficial Effects

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] In this solution, the pull rod is pulled downward to squeeze the telescopic rod and the spring through the movable plate and drive the insertion rod to move upward and away from the inner cavity of the mounting plate. At this time, the bracket is placed into the mounting block and the mounting plate is inserted into the mounting block. The pull rod is then released and the elastic force of the spring itself is used to drive the movable plate and the insertion rod to move upward again into the inner cavity of the mounting block and the mounting plate, thereby limiting the bracket and installing it on the mounting block. The bracket can be easily installed and disassembled by simply pulling the pull rod to move. Compared with the traditional bolt-fixed installation method, it is simpler and more convenient, and can reduce the difficulty of operators installing the bracket underground.

[0017] This solution uses a bracket to ensure that the detection probe at the lower end will be located at the bottom of the sewage pipe after installation, continuously monitoring the sewage flow, and indirectly indicating possible pollutant emission problems by identifying flow abnormalities, thereby achieving indirect monitoring and alarm of pollutants in the sewage well. The bracket provides a stable installation foundation for the detection probe, which can prevent the detection probe from shifting or tilting due to water flow impact or external force.

[0018] This solution protects the outer surface of the wire connecting the detection probe and the flow meter body by inserting it into a wire tube sleeve, thereby preventing the outer surface of the wire from being squeezed, cut or worn by pollutants, which would affect the normal use of the wire and improve the safety of the device. The wire tube sleeve can be disassembled by turning and removing the bolts that fix the pipe clamp, making it convenient for operators to install and use it flexibly.
