Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a double screw lifting gate ice melting disturbance device. Background Technology

[0002] In northern my country and high-altitude, cold regions, reservoir gates are subject to the combined effects of extreme low temperatures (often below -10°C) and continuous water conveyance during winter operation. This leads to the formation of stable ice sheets on the water surface around the channels and gates, with the ice thickness varying with the duration of the low temperatures. On one hand, the ice sheets directly hinder the raising and lowering of the gates, preventing precise adjustment of the water flow according to scheduling needs. In severe cases, this can cause channel water levels to rise, overflow, or water wastage due to the gates' inability to close. On the other hand, the freezing and adhesion of the ice to the gates generates significant frictional resistance during operation, accelerating the wear and deformation of the gate's metal structure, shortening equipment lifespan, and increasing maintenance costs.

[0003] Currently, traditional de-icing methods mainly rely on manual labor, requiring workers to manually break the ice layer on the ice surface or canal bank using tools such as picks and hammers. This is not only extremely labor-intensive and inefficient, but the ice fragments generated during the process can also clog the gaps in the gates with the water flow, further affecting equipment operation. There are also devices that use robotic arms to drive ice-breaking blades to impact the ice layer, but these devices are bulky and require large machinery for traction, making them difficult to operate flexibly in the narrow areas in front of the gates. Furthermore, the rigid impact can easily cause impact damage to the gates and the concrete structure of the canal. In addition, they can only break the surface ice layer and cannot solve the problem of ice freezing and sticking to the gates. Utility Model Content

It features a reasonable structural design, mechanical operation, and de-icing mechanism, saving time and effort while improving work efficiency.

[0025] Optionally, the ice-melting assembly includes a bent pipe 19 connected to the two side guide pipes 17 respectively, and an ice-melting pipe 20 arranged in a serpentine pattern is horizontally arranged below the bent pipe 19.

[0028] Optionally, aluminum silicate fiber material 31 is filled between the inner tank 10 and the outer tank 11. The aluminum silicate fiber material 31 can further improve the heat insulation efficiency, thereby reducing the heat loss generated by the inner tank 10.

[0029] When ice melting is required in winter, this device can be operated. First, the lifting motors 5 on both sides are controlled to work, and the crossbeam 3 moves downward through the lead screws 6 on both sides, driving the corresponding threaded seats 32 on each side. As the crossbeam 3 moves, the support frame 8 moves downward through the square steel pipe 7, thereby controlling the bottom of the ice melting mechanism to contact the ice surface. Then, each heating rod 15 is turned on to heat the liquid in the inner tank 10, while the outer tank 10 mainly serves to keep the liquid warm and reduce heat loss. After the liquid in the inner tank 10 reaches the required temperature, the circulation pump 18 is started, causing the liquid to flow downward from the guide pipe 17 on the left side, through the bend pipe 19, into the ice melting pipe 20, thereby transferring heat to the ice layer and melting the ice. The liquid that has consumed heat returns to the inner tank 10 through the bend pipe 19 and the guide pipe 17 on the right side, and is then heated by the heating rods 15 to raise its temperature. As the ice in front of the gate melts, the crossbeam 3 slowly moves downward until the ice layer completely melts, and the ice layer connected to the gate also melts. At this time, to prevent the water area from freezing again, the drive motor 27 drives the active pulley 28 to rotate, which in turn drives the other three driven pulleys 24 to rotate via the belt 30, thereby driving the stirring wheels 26 to agitate the water surface and slow down the freezing rate. Its reasonable structural design and mechanical operation, using an ice-melting method, save time and labor, improve work efficiency, and avoid the impact damage to the gate and channel concrete structure caused by forceful ice breaking. It also prevents ice fragments from clogging the gate gaps and effectively removes ice layers that are frozen and adhered to the gate, allowing the gate to open and close smoothly, extending the gate's service life, and solving the problems existing in the prior art.
