Description

Technical Field

[0001] This utility model relates to the field of pipeline blockage prevention and dredging technology, specifically a reservoir dredging device for preventing blockage of sludge discharge pipes. Background Technology

[0002] Reservoirs play a vital role in water conservancy systems, serving functions such as flood control, irrigation, water supply, and power generation. However, over time, silt accumulates within reservoirs. Large amounts of silt buildup reduce the effective storage capacity of the reservoir. For example, when siltation reaches a certain level, the reservoir's flood control capacity decreases, potentially failing to effectively contain flood peaks and increasing the risk of downstream flooding. In terms of water supply and irrigation, the amount of usable water decreases, impacting water demand in surrounding areas.

[0003] A search revealed a pneumatic-hydraulic combined reservoir dredging device disclosed in Chinese Patent Publication No. CN111236142B. This device includes a spillway dam and a reservoir connected together. Several air tanks are mounted on the spillway dam, with adjacent tanks connected via an air compressor. Each air tank is connected to a water-based air supply pipe leading to the bottom of the reservoir. The end of this water-based air supply pipe is connected to a sand-lifting pipe with an exhaust port. A disturbance pipe with a disturbance cutter is located between adjacent water-based air supply pipes. One end of this disturbance pipe is connected to an inclined inlet pipe, and the other end is connected to an outlet pipe located at the bottom of the spillway dam. The upper part of the spillway dam has several sand-discharging holes, and the lower part has several sand-discharging bottom holes. This structure is suitable for the bottom of the reservoir but cannot automatically propel silt forward; accumulated silt easily accumulates in the pipes. Therefore, this pneumatic-hydraulic combined reservoir dredging device needs further improvement. Hence, a reservoir dredging device with anti-clogging sludge discharge pipe is proposed.

It has advantages such as being less prone to pipe blockage, being able to rotate and clean the sludge inside the pipe, and having a simple structure, thus solving the problem of pipe blockage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reservoir dredging device for preventing clogging of the sludge discharge pipe, comprising a rotating mechanism, a first rotating ring, a second rotating ring, a fixed plate, a connecting rod, and a spiral conveying plate, wherein the rotating mechanism is provided with several components at equal intervals;

[0006] The first rotating ring is provided with several equally spaced rings and is spaced apart from the rotating mechanism. The second rotating ring is movably connected to the inner side of the first rotating ring. The rotating mechanism and the first rotating ring are staggered and equally spaced. The first rotating ring and the rotating mechanism are connected by several equally spaced connecting pieces. Each rotating mechanism and the inner ring of the second rotating ring are fixedly connected with several equally spaced conveying pieces.

[0007] Furthermore, in the rotating mechanism, a gear ring meshes with a gear, and the gear is fixedly connected to the output shaft of the motor.

[0008] Furthermore, the inner ring of the first rotating ring is provided with a rectangular groove.

[0009] Furthermore, a slider is fixedly connected to the outer ring of the second rotating ring.

[0010] Furthermore, the slider is movably fitted into the groove.

[0011] Furthermore, the fixing plates are evenly distributed on the outer ring of the first rotating ring, and each fixing plate is provided with a connecting hole.

[0012] Furthermore, the connector is a connecting rod, which is circumferentially arranged and has multiple toothed rings and a second rotating ring fixedly connected at intervals on it.

[0013] Furthermore, the conveying component is a conveying plate, and the conveying plate is provided in several groups, with several conveying plates evenly spaced in each group. The conveying plate is set as an arc-shaped plate and extends in a spiral shape. The conveying plates are all inclined towards a square shape. The toothed ring and the inner ring of the second rotating ring are both fixedly connected to a set of conveying plates.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] In this invention, the first rotating ring is directly screwed into the pipe via a fixed plate to increase stability; the second rotating ring is movably connected to the first rotating ring via a slider, so that the second rotating ring does not detach from the first rotating ring during operation, and ball bearings are added at the connection point to increase sliding performance; the conveying plates are inclined and spirally extended, and all are inclined in one direction, so that the sludge can be pushed forward when the entire device is running.

The motor 12 is bolted into the pipe and waterproofed. The gear ring 10 and the inner ring of the second rotating ring 3 are fixedly connected to a conveying component, which is a conveying plate 6. A rectangular groove 20 is machined in the middle of the inner ring of each first rotating ring 2 to allow the second rotating ring 3 to be movably connected to the inner ring of the first rotating ring 2. Several equally spaced fixing plates 4 are welded to the outer ring of the first rotating ring 2. Each fixing plate 4 has a connecting hole 40, which is connected to the pipe by screws to increase the stability of the equipment.
