Description

Technical Field

[0001] The invention belongs to the technical field of pond desilting, and in particular relates to a desilting and sand-discharging device suitable for water storage ponds in piedmont alluvial plain irrigation areas. Background Art

[0002] In areas with arid climate and water shortage, water storage ponds play a vital role in production and life. However, due to river scouring and sandstorms, the water body contains a lot of sand, and the problem of siltation in water storage ponds is particularly prominent. Due to the interception of dams, the slowdown of water potential and the backwater of water storage ponds, silt accumulates in water storage ponds, especially at the tail of dams and water storage ponds. Since water storage ponds in areas with arid climate and water shortages lack sand discharge devices in their early designs, silt accumulates more and more in water storage ponds, seriously affecting the practical functions of water storage ponds. In recent years, with the continuous improvement of pond breeding technology, the input of fish fry, feed, fertilizer, etc. in ponds has continued to increase, and the silt at the bottom of the pond has also continued to thicken. In the long run, the accumulation of silt and pollutants not only affects the water quality safety of water storage ponds, but also increases certain safety hazards. It will also have a great impact on the production and living water and environment of residents in the Hexi Irrigation District.

[0003] Traditional pond sludge dredging methods mainly include dry and wet methods. In the process of dry dredging, aquatic plants and animals are prone to die during transportation, which will cause ecological damage and may produce certain noise. It has problems such as low efficiency and high labor intensity. It is only suitable for small ponds and lakes. The wet dredging method can be used for dredging with small dredgers and dredging equipment. However, when operating in small ponds that need to keep water in them for a long time, traditional dredgers are limited by the size of the hull and the excavation depth. It is not suitable to use large equipment such as dredgers and dredging equipment for dredging.

[0004] To this end, those skilled in the art have proposed a silt removal and sediment removal device suitable for water storage ponds in piedmont alluvial plain irrigation areas to solve the problems raised by the background technology.

[0005] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field. Summary of the invention

[0006] The object of the present invention is to provide a silt removal and sand removal device suitable for water storage ponds in piedmont alluvial plain irrigation areas, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A device for desilting and removing sand from a water storage pond in an irrigation area of ​​a piedmont alluvial plain, comprising:

[0009] A dredging mechanism, the dredging mechanism comprises a sand removal pool and a water reservoir, the water reservoir comprises a solar traction boat, a sand removal pipe traction device and a silt stirring device are arranged below the solar traction boat, and the sand removal pipe traction device is connected to a sand removal pipe at one end away from the solar traction boat;

[0010] The transmission mechanism includes a plurality of sand dividing pipes connected to one end of the sand discharge pipe, the sand dividing pipes are communicated with the sand discharge pipe, the sand discharge pool includes a plurality of grading pools, the number of the sand dividing pipes is adapted to the grading pools, and a sand inlet is provided at one end of the sand discharge pipe away from the sand dividing pipe.

[0011] Preferably, the sand inlet is located in the water reservoir, one end of the sand separation pipe is connected to a sand outlet, and the sand outlet is located in the classification tank.

[0012] Preferably, the height of the sand separation pipe is lower than the sand inlet.

[0013] Preferably, a sand discharge pump is provided at one end of the sand discharge pipe close to the sand discharge pool.

[0014] Preferably, a sand separation valve is provided on the side surface of the sand separation pipe.

[0015] Preferably, the solar traction boat is provided with a visual infrared scanning device and a solar panel.

[0016] Preferably, the sand discharge pipe traction device and the sediment stirring device both include a lifting cylinder and a lifting column, the lifting column and the lifting cylinder are slidably matched, a pulling sleeve is provided at one end of the sand discharge pipe traction device, and the sand discharge pipe is installed in the pulling sleeve.

[0017] Preferably, one end of the lifting column on the sediment stirring device is fixedly connected to a driving device, and the driving device includes a driving motor and a spiral stirring blade arranged on an output shaft of the driving motor.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present invention arranges a sand discharge pool downstream of a water reservoir, and arranges a solar traction boat on the water reservoir. A sand discharge pipe traction device with a telescopic function and a sediment stirring device are connected below the solar traction boat. A sand discharge pipe with a sand inlet is sleeved on one end of the sand discharge pipe traction device, and the sand discharge pipe traction device is installed behind the sediment stirring device to break up general obstacles such as plastic sheets and water plants to reduce the blockage of the sand discharge pipe. The sand discharge pipe is arched in the vertical plane. The downstream sand outlet of the sand discharge pool is lower than the upstream sand inlet. With the help of the water level difference between the upstream and downstream, a vacuum is created in the pipe by a sand discharge pump at the sand outlet end at the start of work, and the water-sand mixture is allowed to enter the sand discharge pool from the water reservoir through the sand discharge pipe by utilizing liquid gravity and atmospheric pressure.

[0020] (2) The present invention provides a plurality of longitudinally distributed sand discharge pipes, and the sand discharge pool is further divided into a plurality of classification pools. The sand separation pipes are connected to each classification pool one by one, thereby achieving the effect of classifying the particle size of the sediment. The function of the sand separation pipes is to control the flow rate through the sand separation valve and the sand discharge pump by utilizing the sedimentation principle of the sediment, so that when the sediment flows through the sand separation pipes, particles of different diameters settle at different heights and enter different classification sedimentation pools through different sand separation pipes, thereby achieving the classification of the sediment particle size, thereby reducing the screening process for subsequent construction sand.

[0021] (3) The present invention provides a sand discharge pump at the end of the sand discharge pipe. When the sand discharge pump is in operation, it can create a vacuum in the sand discharge pipe and can be opened when the siphon power is insufficient or the pipe is blocked, thereby improving the sand discharge efficiency. The sand separation valve is used to control the opening and closing of each sand separation pipe. The solar traction boat is equipped with a visual infrared scanning device and a solar panel. The solar panel and the lithium battery on the hull are jointly powered. During the day, it is powered by solar energy, automatically charges and stores electricity in the lithium battery, ensuring that it can still work normally on cloudy days or at night. The visual infrared scanning device is used to scan the underwater silt accumulation situation, so that the solar traction boat can move to the location where silt needs to be cleared.

[0022] (4) When the solar tugboat starts working, it scans the underwater silt accumulation through a visual infrared scanning device, and pulls the silt pipe to the silt surface through a retractable silt pipe traction device. At the same time, the spiral stirring blade stirs the bottom silt to make it easier for the silt to enter the silt pipe, thereby improving the dredging efficiency. The device is more convenient to disassemble due to its simple separation design, has a wide range of applications, and has a low cost. The solar boat scans the reservoir area. The silt pipe traction device is combined with the silt pipe and the silt stirring device to stir the silt first, making the cleaning range wider and more thorough. The siphon is created by using solar energy, liquid pressure, and liquid level difference to achieve the functions of sand discharge and silt particle size classification, saving labor and reducing construction difficulty. At the same time, the cleaned silt can be used in construction and other aspects according to different particle sizes.

[0023] The above summary is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present invention will be readily apparent by reference to the accompanying drawings and the following detailed description.
