Water conservancy ecological engineering desilting device

Abstract

The invention provides a water conservancy ecological engineering desilting device which comprises a base and a collecting box, and a plurality of anti-supercooling assemblies capable of preventing the surface temperature of the collecting box from being too low are fixedly installed at the lower ends of the outer surfaces of the front side, the rear side and the left side of the collecting box in an equally adjacent mode. The anti-supercooling assembly comprises a shell, a moving assembly capable of automatically moving under the cold condition and a heating assembly capable of generating high-temperature heat. A plurality of shells are fixedly installed at the lower ends of the outer surfaces of the front side, the rear side and the left side of the collecting box in an equally adjacent mode, each shell is in a hollow and totally-closed cylindrical shape, and the shells are made of copper. According to the desilting device for the water conservancy ecological engineering, the effect that the collecting box has an anti-supercooling function can be achieved, even if the desilting device works in cold weather in winter, residual water in the blow-off pipe is not prone to icing due to the outdoor low temperature, ice blocks in the blow-off pipe can be dredged in time before operation, and normal operation of the desilting device is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, and more particularly, to a dredging device for water conservancy and ecological engineering. Background technique [0002] The existing dredging device has poor dilution effect on the silt during use, and the presence of weeds in the silt will cause blockage of the river, affecting the dredging effect, and it is inconvenient to disassemble and clean the filter screen. [0003] In view of the above problems, regarding the technical problems such as the poor dredging effect of the existing dredging devices, after a lot of searches, we found an adjustable dredging device for water conservancy projects with the patent number of CN202120084547.X, including the base The top of the base is provided with a collection box, one side of the collection box is provided with a mounting plate that is slidably connected to the base, the top of the mounting plate is provided with a hydrauli...

Problems solved by technology

[0002] The existing dredging device does not have a good dilution effect on the silt during use. Due to the presence of weeds in the silt, it will block the river course, affect the dredging effect, and it is inconvenient to disassemble and clean the filter screen

[0003] In view of the above problems, regarding the technical problems such as the poor dredging effect of the existing dredging device, after a large number of searches, we found an adjustable dredging device for water conservancy projects with the patent number CN202120084547.X, including the base , the top of the base is provided with a collection box, one side of the collection box is provided with a mounting plate slidingly connected with the base, the top of the mounting plate is provided with a hydraulic rod, the top of the hydraulic rod is provided with a fixed plate, and one side of the fixed plate is fixed with a dredging cylinder. A dredging motor is installed on the top of the dredging tank. The output end of the dredged motor extends to the inside of the dredged tank and is connected with a screw rod. There is a dredging pump installed on the top of the collecting tank, and a hose is installed at the suction end of the dredging pump. One end of the dredging pump is in communication with the top of the side of the dredging cylinder close to the collection box. A filter is installed inside the collection box, and the bottom of the collection box away from the dredging cylinder is provided with a sewage outlet for discharging sludge. By setting the filter It can filter the impurities in the silt, and at the same time, it is easy to disassemble and clean the filter screen. During operation, the low temperature outside will easily cause the residual water in the sewage pipe to freeze. If the ice in the sewage pipe is not cleared in time before the operation, the normal operation of the dredging device will be affected.
