Description

Technical Field

[0001] The utility model belongs to the technical field of reservoir silt cleaning, and particularly relates to a reservoir bottom silt cleaning mechanism. Background Technique

[0002] A reservoir is generally interpreted as "a hydraulic engineering structure for flood interception, water storage and water flow regulation, which can be used for irrigation, power generation, flood control and fish farming". It refers to an artificial lake formed by building a dam across a mountain valley or a narrow section of a river. Many reservoirs have the problem of sediment deposition. The silt problem of the reservoir directly affects the use and comprehensive benefits of the reservoir, and even endangers the safety of the reservoir dam in severe cases. Especially for reservoirs built on sediment-laden rivers, the silt problem is more prominent. Therefore, removing the silt and sediment in the reservoir is an important way to maintain the reservoir and the dam. During the silt cleaning process, a silt cleaning mechanism is needed.

[0003] During the operation of the existing silt cleaning mechanism, the silt at the bottom of the reservoir is pumped at a specified position through a sludge suction pump. Since the silt at the bottom of the reservoir accumulates and forms lumps, and contains a large amount of impurities, it is difficult to directly suck it out. Moreover, during the process of sucking out large lumps of silt, due to the large amount of impurities in the silt, the sludge suction pump is extremely prone to blockage during operation, resulting in the device stopping running and being unable to operate normally, and at the same time reducing the silt cleaning efficiency. Therefore, we provide a reservoir bottom silt cleaning mechanism. Content of the Utility Model

[0004] The purpose of the utility model is to provide a reservoir bottom silt cleaning mechanism, which is used in cooperation with a sludge conveying pipe, a sludge suction head, a sludge suction pump and a sludge guiding pipe through the settings of a first motor, a winding roller, a steel wire rope, a fixing plate, a second motor, a connecting block, a crushing roller and crushing blades, so as to solve the problems raised in the above background technique.

[0005] To achieve the above object, the present utility model provides the following technical solution: A reservoir bottom silt cleaning mechanism, including a hull, a collection box is fixedly connected to the right side of the inner bottom of the hull, an L-shaped frame is fixedly connected to the right side of the top of the collection box, vertical plates are fixedly connected to both sides of the top of the L-shaped frame, a first motor is fixedly installed on one side of the vertical plate, a winding roller is fixedly connected to the output end of the first motor, a steel wire rope is wound around the surface of the winding roller, a fixing plate is fixedly connected to the bottom of the steel wire rope, a second motor is fixedly installed on the bottom of the fixing plate, a connecting block is fixedly connected to the output end of the second motor, a crushing roller is inserted into the inner wall of the connecting block, and the connection between the connecting block and the crushing roller is fixedly connected by a fastening bolt.

At the same time, the second motor drives the connecting block to rotate, the connecting block drives the crushing roller to rotate, the crushing roller drives the crushing blade to rotate, and the crushing blade breaks the large pieces of silt and impurities in the silt. After the crushing is completed, the mud suction pump sucks the silt at the bottom of the reservoir in cooperation with the mud conveying pipe and the mud suction head, and conveys the silt to the inner cavity of the collection box through the mud guiding pipe.
