Description

TECHNICAL FIELD

[0001] The application relates to a reservoir silt removing device. BACKGROUND

[0002] The reservoir can play a role in water storage and flow regulation. Since the reservoir generally comprises an inlet side and an outlet side, the water flow is generally fast at the inlet side, and in the reservoir, due to the large storage capacity, the flow rate suddenly slows down, and the silt in the water flow will settle at the bottom of the reservoir. With the increase of time, the reservoir bottom will be higher and higher, which will obviously affect the reservoir capacity, so it is necessary to carry out continuous desilting treatment on the reservoir. The existing desilting method is mainly to use the pump suction method, but the current pump suction method cannot suck the water flow with high content of silt, and the desilting effect is limited.

The impact nozzle is used to impact the silt, which plays a role in lifting the silt. After the silt is lifted, it is guided out of the collecting pipeline, and then guided out of the outlet pipeline by the outlet pump, that is, the silt is guided out.

[0004] Preferably, the impact nozzle comprises a fixed shell, a submersible pump is arranged in the fixed shell, a water inlet filter screen is arranged on the side of the water inlet of the submersible pump, the water inlet filter screen is arranged on the fixed shell, a diffusion cavity is arranged below the submersible pump, and an outer outlet channel is arranged below the diffusion cavity.

[0006] Preferably, an arc-shaped plate is arranged at the top of the collecting pipeline, the arc-shaped plate is arranged to be curved inward, and the end nozzle is clamped on the arc-shaped plate. The arc-shaped plate can protect the end nozzle, and prevent the silt from damaging the end nozzle.

[0007] Preferably, a power cable connected with the submersible pump is arranged at the top of the fixed shell.

[0008] Preferably, an outer connecting frame body is arranged at the top of the collecting pipe, the outer connecting frame body comprises a ring-shaped sleeve joint, and a lower support table is arranged below the sleeve joint. The application can be assembled by arranging the lower support table on a ship or other support body, and then placing the collecting pipe on the lower support table through the sleeve joint, thereby achieving the purpose of sludge removal.

[0009] Preferably, an upper closed flange is arranged at the top of the collecting pipe, and a closed blind plate is bolted to the upper closed flange.

[0010] Preferably, an outer connecting flange for connecting the outlet pump is arranged at the end of the outlet pipe.

[0011] The application can bring the following beneficial effects:

[0012] 1. The application uses the impact nozzle to impact the sludge, which plays a role in lifting the sludge. After the sludge is lifted, it is guided out of the collecting pipe, and then guided out of the outlet pipe by the action of the outlet pump, thereby completing the guiding out of the sludge.
