Referring to fig. 1-3, the present invention provides a technical solution: a pump station stuffing box water leakage detection device comprises a mounting sleeve 1 and a water storage box 6, wherein the mounting sleeve 1 is of a hollow cylindrical structure with openings at two ends and is used for being mounted on the output end of a water pump to be detected, the top of the mounting sleeve 1 is cut open, two cross sections of the mounting sleeve are bent upwards to form two mounting plates 2 which are parallel to each other, and the two mounting plates 2 are connected through fastening bolts 3; the bottom of the mounting sleeve 1 is open and provided with a water guide port 5 extending downwards, and the top of the water storage box 6 is communicated with the lower end of the water guide port 5; 6 bottom one side of water storage box is connected with

drain pipe

7, and 6 opposite sides laminating of water storage box is installed and is leaked

response box

9, and 6 upper portion one side of water storage box is seted up and is leaked the overflow hole 10 that responds to box 9 intercommunication, and the response box 9 internally mounted that leaks has liquid level sensor 11, installs siren 12 on the response box 9 that leaks.

Furthermore, a circle of water retaining ring 4 is embedded in the outer end face of the mounting sleeve 1.

Further, a flow control valve 8 is installed on the drain pipe 7.

Further, the lower end of the water leakage induction box 9 extends downwards, the bottom of the water leakage induction box 9 is lower than the water storage box 6, and a water outlet 13 with a sealing cover is arranged at the bottom of the water leakage induction box 9.

Further, a PLC controller is integrated in the alarm 12, and the PLC controller is connected with the output end of the liquid level sensor 11 and connected with the control end of the alarm 12.

The working principle is as follows: during the installation, establish the one end at the stuffing box place of being surveyed the water pump with 1 cover of installation cover, and the installation cover 1 outer end outwards stretches out a section distance, then utilizes fastening bolt 3 to lock two mounting panels 2, accomplishes the fixed of device, and 1 outer end inner wall of installation cover inlays and adorns water retaining ring 4 and block, and the water of avoiding spilling is excessive.

In the daily operation of the water pump to be detected, water drops are intermittently dropped from the gap between the stuffing box and the water pump, and the leaked water slides along the inner wall of the mounting sleeve 1 to the water guide port 5 and then falls into the water storage box 6 for collection; the drain pipe 7 at one side of the bottom of the water storage box 6 is a thin conduit, the tail end of the thin conduit is led into a ditch, a sewer and the like, and the drainage speed of the thin conduit is adjusted by a flow control valve 8 on the drain pipe 7, so that the drainage quantity of the thin conduit is consistent with the dripping quantity of the stuffing box; under the normal sealing state, the water inflow and the water outflow in the water storage box 6 are the same, and the liquid level height is unchanged.

When the stuffing box is not hard up, when the volume of leaking water grow, the inflow in the water storage box 6 is greater than the water yield, its inside liquid level height risees gradually, reach to overflow hole 10 when locating, water gets into in the response box 9 that leaks through overflow hole 10, liquid level inductor 11 acquires the liquid level change data in the response box 9 that leaks in real time, and send to the PLC controller end in siren 12, when the liquid level change value reaches the threshold value of settlement, PLC controller triggers siren 12 and sounds, remind the staff unusual to leak, can in time discover and carry out maintenance process when leaking unusually, be convenient for keep the stable operating condition of water pump.

It is worth noting that: the whole device realizes control to the alarm 12 through a PLC controller therein, and since the control matched equipment is common equipment, the device belongs to the prior mature technology, and the electrical connection relation and the specific circuit structure are not repeated herein.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
