Description

TECHNICAL FIELD

[0001] The utility model belongs to the sluice dredging technical field, especially relate to a sluice bottom dredging device. BACKGROUND

[0002] In water conservancy projects, the sluice is an important facility for regulating water flow and flood control and drainage. However, after a period of operation of the sluice, a large amount of silt, sand and other impurities often accumulates at the bottom of the gate. These silt materials not only cause the gate to be unable to completely close, affecting the control accuracy of the water flow, but also can cause wear to the sealing structure at the bottom of the gate, thereby reducing the operating efficiency and service life of the sluice. Therefore, how to efficiently clean the silt at the bottom of the gate has become a key problem in the maintenance of the sluice.

[0003] Traditional dredging methods usually rely on manual or mechanical excavation equipment, but these methods have problems such as low efficiency, complex operation, high cost, etc. In addition, during the cleaning process, the water flow may wash the silt and impurities in front to the bottom of the gate, resulting in limited dredging effect, and even requiring multiple cleanings, increasing the difficulty and time cost of work.

[0004] In order to solve the above technical problems, some new dredging equipment has appeared on the market, for example, patent document CN116427488A describes a sluice dredging device. The patent mainly uses a silt suction pump and a pipe system to suck the silt out from the bottom of the gate, and its dredging method relies on strong suction force to directly transport the silt to a specific storage location. This method effectively reduces the complexity of manual operation, and to some extent, achieves rapid dredging. However, the suction design of this patent focuses on the rapid transfer of silt, but pays less attention to preventing secondary silt accumulation caused by water flow, especially in an environment with strong water flow, there may be a risk of silt and impurities in front being washed to the bottom of the gate by the water flow. In addition, the suction device of this patent needs to rely on high mechanical energy input, which has high operating cost.

[0005] In order to solve the above problems, we provide a sluice bottom dredging device which can clean the bottom of the sluice and avoid the water flow from piling up the silt on the upstream ground again at the bottom of the sluice during the cleaning process. CONTENT OF THE UTILITY MODEL

[0010] When the gate needs to be lowered, the sludge and the like below the gate need to be removed, if there is a large amount of sludge or sundries below the gate, the gate cannot be completely lowered, and the water gate cannot be completely closed; before the gate is lowered, the controller is controlled to control the lifting electric cylinder to extend and drive the bulkhead to move downwards until the bulkhead is attached to the ground, and the bulkhead can effectively prevent the sludge and the like in the water below the gate from entering the gate below along with the water flow. The controller controls the electric cylinder one and the electric cylinder two to drive the lifting plate to move downwards at the same time, and controls the electric cylinder three to extend at the same time, drives the transmission rod two to rotate, and then drives the push plate to move along the ground, pushes the sludge below the gate backwards, and then cleans the sludge and the like below the gate.

After the sludge below the gate is cleaned, the push plate is reset, the bulkhead is reset, and then the gate is lowered.

[0011] When the push plate needs to be rotated (so as to push the sludge and the like in the gate downwards or upwards), the extension length of the electric cylinder one and the electric cylinder two is controlled to change the angle of the lifting plate, and then the angle between the push plate and the ground is changed.
