Description

Technical Field

[0001] The utility model belongs to the technical field of underground drainage equipment, in particular to an underground hidden noise-reducing automatic drainage equipment. Background Art

[0002] During the underground construction of mining, water seepage will occur due to geological conditions. In order to ensure the normal operation of the mine, a pump pit will be excavated to collect the seepage water in the underground mine, and then the water will be pumped out through the drainage device, and then drained through the underground drainage facilities. In the process of work, the safety of underground operations is ensured. In order to prevent safety accidents such as falling into water during the work, the pump pit needs to be designed to be hidden to ensure work safety. However, it still has the following disadvantages in actual use:

[0003] 1. In the process of working, in order to ensure stable operation and reduce the potential safety hazards caused by high humidity in the circuit, the underground hidden automatic drainage equipment needs to be equipped with a pneumatic diaphragm pump to reduce disturbances during work. During the operation of the pneumatic diaphragm pump, a large amount of noise pollution will be generated, which may cause great harm or impact on the health of construction workers;

[0004] 2. When the underground hidden automatic drainage equipment is working, the bottom of the pipe is directly placed in the accumulated water. The water is pumped out during the operation of the pneumatic diaphragm pump. During the water extraction process, in order to drain the accumulated water, a hose is required at the bottom of the pipe. During the operation of the hose, the end is easy to stick to the inner wall of the pump pit, causing negative pressure suction, which affects the operation efficiency. Utility Model Content

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses an underground hidden noise-reducing automatic drainage device, comprising an underground pump pit, a pump pit cover, an air-operated diaphragm pump and a bottom hose, wherein a pump pit step is fixedly provided in the underground pump pit, a pneumatic diaphragm pump is arranged on the top of the pump pit step, an output end of the pneumatic diaphragm pump is fixedly connected with a water suction pipe, an end of the water suction pipe away from the pneumatic diaphragm pump is fixedly connected with a bottom hose, a pump pit cover is arranged on the top of the underground pump pit, a silencer is fixedly provided at the bottom center of the pump pit cover, and the silencer is movably connected to the upper part of the inner wall of the underground pump pit. When working, water in a main pump pit is connected through a drainage pipe through the underground pump pit, and the accumulated water in the main pump pit flows into the underground pump pit, the top of the underground pump pit is closed by the pump pit cover, and the noise generated by the pneumatic diaphragm pump is absorbed by the silencer, and the top of the underground pump pit is closed by the pump pit cover, and the accumulated water in the underground pump pit is sucked into the underground pump pit through the bottom hose by the pneumatic diaphragm pump.

[0008] Furthermore, movable openings are symmetrically opened at the top of the pump pit step, and bases are symmetrically fixed at the bottom of the pneumatic diaphragm pump. The two bases are movably connected in the two movable openings respectively, and the pump pit step is movably connected to the bases through the movable openings, so that the pneumatic diaphragm pump is stably supported on the pump pit step.

[0009] Furthermore, the output end of the pneumatic diaphragm pump is fixedly connected to a water outlet pipe, and the power input end of the pneumatic diaphragm pump is fixedly connected to an air inlet pipe. The pneumatic diaphragm pump transports the water pumped therein to the drainage pipe in the underground tunnel through the water outlet pipe, and inputs the air in the compressed air pipe into the pneumatic diaphragm pump through the air inlet pipe.

[0010] Furthermore, a fixing hole one is vertically opened in the pump pit cover and the silencer plate corresponding to the position of the air inlet pipe, and a fixing hole two is vertically opened in the pump pit cover and the silencer plate corresponding to the position of the water outlet pipe. The pump pit fixes the air inlet pipe through the fixing hole one, and the pump pit fixes the water outlet pipe through the fixing hole two.

[0011] Furthermore, the water outlet pipe is vertically passed through and fixed in the second fixing hole, and the air inlet pipe is vertically passed through and fixed in the first fixing hole, so that the water outlet pipe and the air inlet pipe extend out of the pump pit cover.

[0012] Furthermore, the bottom end of the bottom hose is fixedly connected to a hollow ball, which is arranged in the lower part of the downhole pump pit. The outer side of the hollow ball is provided with water inlet holes in a circular array, and the bottom hose is filled with water through the water inlet holes on the hollow ball.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model solves the problem that the pneumatic diaphragm pump in the underground hidden automatic drainage equipment is prone to generate large noise pollution by arranging an underground pump pit, a pump pit cover and a pneumatic diaphragm pump. The pump pit cover fixes the silencer plate at its bottom, which is movably connected to the upper part of the underground pump pit through the silencer plate to absorb the noise generated by the pneumatic diaphragm pump in the underground pump pit, so that the noise generated by the pneumatic diaphragm pump in the underground hidden automatic drainage equipment can be well absorbed, thereby reducing noise pollution.

[0015] 2. The utility model solves the problem that the flexible end of the input pipe of the pneumatic diaphragm pump in the underground hidden automatic drainage equipment is easily sucked by negative pressure and affects the operation efficiency by arranging an underground pump pit, a pneumatic diaphragm pump and a bottom hose. The pneumatic diaphragm pump generates negative pressure when working, which causes negative pressure in the water suction pipe and negative pressure in the bottom hose. The bottom hose inputs the accumulated water in the underground pump pit into it through the water inlet holes opened on the outside of the hollow ball, and water is taken in through the water inlet holes at various positions on the outside of the hollow ball to prevent the bottom end of the bottom hose from just contacting the bottom or side wall of the underground pump pit and being blocked by the negative pressure generated by the pneumatic diaphragm pump, so that the flexible end of the input pipe of the pneumatic diaphragm pump in the underground hidden automatic drainage equipment can maintain smooth operation.

The underground pump pit 1 is connected with the main pump pit through a drainage pipe, so that the accumulated water in the main pump pit flows into the underground pump pit 1. The air-operated diaphragm pump 3 is supported on the pump pit step 101. The top of the pump pit step 101 is provided with an air-operated diaphragm pump 3. The air-operated diaphragm pump 3 is used to extract the accumulated water at the bottom of the underground pump pit 1. The output end of the air-operated diaphragm pump 3 is fixedly connected with a water suction pipe 302. The diaphragm pump 3 is connected to the bottom hose 4 through the suction pipe 302. The end of the suction pipe 302 away from the pneumatic diaphragm pump 3 is fixedly connected to the bottom hose 4. The water accumulation position of the downhole pump pit 1 is connected to the suction pipe 302 through the bottom hose 4. A pump pit cover 2 is provided on the top of the downhole pump pit 1. A silencer plate 201 is fixed to the bottom center of the pump pit cover 2. The silencer plate 201 is movably connected to the upper part of the inner wall of the downhole pump pit 1. The pump pit cover 2 fixes the silencer plate 201 at its bottom and is movably connected to the upper part of the downhole pump pit 1 through the silencer plate 201 to absorb the noise generated by the pneumatic diaphragm pump 3 in the downhole pump pit 1.

[0027] Specifically, movable openings 102 are symmetrically opened at the top of the pump pit step 101, and bases 301 are symmetrically fixed at the bottom of the pneumatic diaphragm pump 3. The two bases 301 are movably connected in the two movable openings 102 respectively. The pump pit step 101 is movably connected to the base 301 at the bottom of the pneumatic diaphragm pump 3 through the movable openings 102, so that the pneumatic diaphragm pump 3 is stably supported on the pump pit step 101.

[0028] Furthermore, the output end of the pneumatic diaphragm pump 3 is fixedly connected to a water outlet pipe 303, the top of the water outlet pipe 303 is fixedly connected to the underground main lane drainage pipe, and the power input end of the pneumatic diaphragm pump 3 is fixedly connected to an air inlet pipe 304, the top of the air inlet pipe 304 is connected to the compressed air pipe, so that the high-pressure air in the compressed air pipe is input into the pneumatic diaphragm pump 3, and the pneumatic diaphragm pump 3 outputs the water pumped into it to the underground main lane drainage pipe through the water outlet pipe 303 and discharges it, and transports the high-pressure air in the underground compressed air pipe to the diaphragm pump through the air inlet pipe 304.

[0029] Furthermore, a fixing hole 1 202 is vertically penetrated in the pump pit cover plate 2 and the muffler plate 201 corresponding to the position of the air inlet pipe 304, and a fixing hole 203 is vertically penetrated in the pump pit cover plate 2 and the muffler plate 201 corresponding to the position of the water outlet pipe 303. The pump pit cover plate 2 fixes the air inlet pipe 304 through the fixing hole 1 202, and fixes the water outlet pipe 303 through the fixing hole 203.

[0030] Furthermore, the water outlet pipe 303 is vertically passed through and fixed in the second fixing hole 203, and the air inlet pipe 304 is vertically passed through and fixed in the first fixing hole 202, so that during operation, both the water outlet pipe 303 and the air inlet pipe 304 extend out of the pump pit cover 2.

[0031] The operation process of this embodiment is: when working, the high-pressure air in the compressed air pipe is input into the pneumatic diaphragm pump 3 through the air inlet pipe 304, and the pneumatic diaphragm pump 3 is started. When the pneumatic diaphragm pump 3 is working, a negative pressure is generated in the water suction pipe 302, and the accumulated water in the underground pump pit 1 is sucked into it, and then pumped into the outlet pipe 303 through the pneumatic diaphragm pump 3, and transported to the drainage pipe of the underground main lane through the outlet pipe 303 for drainage. During the operation, the pneumatic diaphragm pump 3 generates noise. After the noise is fully absorbed by the silencer plate 201 at the bottom of the pump pit cover 2, after the pump pit cover 2 is closed, the noise generated by the pneumatic diaphragm pump 3 when working is fully reduced, thereby reducing the noise in the underground main lane.
