Description

Technical Field

[0001] The invention relates to the technical field of water conservancy and hydropower engineering, and in particular to a device for desilting a water channel for water conservancy and hydropower construction. Background Art

[0002] Water conservancy and hydropower engineering mainly studies the basic knowledge and skills of water resources, hydraulic structures, hydraulics and fluid dynamics, and water conservancy engineering technology, and conducts survey, planning, design, construction, and management of water conservancy and hydropower engineering. For example: the construction of hydraulic structures such as hydropower stations, dams, and gates, and the design of river regulation projects.

[0003] A canal is a man-made waterway, which can be divided into a main canal and a branch canal. The main canal and the branch canal are generally built with stone or cement. During the long-term use of the canal, a large amount of silt and debris will be deposited inside the canal, which will affect the flow of water. At the same time, a large amount of silt will be brought into the farmland, affecting the growth of crops. In order to ensure the water flow of the canal, it is necessary to dredge the canal. When dredging the canal, there is some sewage in the canal, which can facilitate the extraction of silt and improve the fluidity of silt.

[0004] The existing canal dredging is mainly carried out by moving a shovel pushed by a mobile vehicle, which can quickly clean the silt inside the canal, extract the silt inside the shovel through a sludge pump, and discharge the silt through a sewage pipe. However, the silt in the canal contains hard objects such as gravel or stones. Since some of the gravel or stones in the silt are large, the gravel or stones will cause damage to the inside of the sewage pipe when they enter the sewage pipe. After the pipe is damaged, it needs to be replaced, which affects the efficiency of the dredging work. Summary of the invention

[0034] The dredging device for water channel used in water conservancy and hydropower construction of the present invention comprises:

[0035] A dredging mechanism 1, used for cleaning and collecting silt in the canal;

[0036] A moving mechanism 2, used for driving the dredging mechanism 1 to move in the canal;

[0037] The crushing mechanism 3 is connected to the silt clearing mechanism 1 and is used for crushing the silt entering the silt clearing mechanism 1 .

[0038] When in use, the dredging device is moved to the canal to be cleaned, the dredging mechanism 1 is turned on, the silt and sewage in the canal are cleaned and collected, the dredging mechanism 1 is driven to move in the canal by the moving mechanism 2, and the crushing mechanism 3 crushes the silt entering the dredging mechanism 1 to avoid blockage of the dredging pipeline due to large gravel or stones in the silt and silt agglomeration, thereby avoiding damage to the dredging pipeline. The mixing of silt and sewage can prevent the crushing mechanism 3 from being contaminated with silt during use, thereby improving the fluidity of the silt and facilitating the dredging work.

[0039] In one embodiment, the crushing mechanism 3 includes a hopper 31 with one side open, a first pressing roller 32 and a second pressing roller 33 arranged in the hopper 31 in an upper and lower distribution, and two power members 34 respectively used to drive the first pressing roller 32 and the second pressing roller 33 to rotate, and a conveying pipe 35 connected to the dredging mechanism 1 is arranged on the side plate of the hopper 31 opposite to the open side. In this design, by setting the conveying pipe 35 connected to the dredging mechanism 1 and the hopper 31, and setting the first pressing roller 32 and the second pressing roller 33 in the hopper 31, the sludge and sewage entering the dredging mechanism 1 must enter through the hopper 31, and the cooperation of the first pressing roller 32 and the second pressing roller 33 can squeeze the sludge, so as to crush larger stones or rocks or agglomerated sludge, and avoid entering the conveying pipe 35 and the dredging mechanism 1 to cause blockage.

[0040] In one embodiment, the mobile mechanism 2 includes a remote control trolley 21 and a roller 22 disposed on the remote control trolley 21, and the lower portion of the front end of the remote control trolley 21 is detachably connected to the hopper 31 through a connecting piece 23.

In this design, by setting the limiting mechanism 4, before dredging the water channel, the position of the limiting plate 41 can be adjusted so that the limiting plate 41 contacts the inner side wall of the water channel to be cleaned, thereby limiting the position of the roller 22, preventing the remote control vehicle 21 from falling into the water channel during use, and ensuring the normal dredging work.

[0044] Preferably, the distance between the two limiting plates 41 and the inner wall of the water channel is less than the distance of half the roller 22, so as to prevent the roller 22 from falling into the water channel during use.

[0045] In one embodiment, the remote control trolley 21 is provided with a slide groove 211 at both ends of the limit plate 41, the limit plate 41 is provided with a slider 43 adapted to the slide groove 211, and the positioning member 42 includes a plurality of positioning holes 421 provided on the groove wall of the slide groove 211 and a positioning screw 422 passing through the positioning hole 421 for positioning the slider 43.

At this time, the sludge is blocked by the first baffle plate 143 and the filter screen 142.

[0048] Under the action of the second blocking plate 111, the sewage in the upper layer is blocked. At this time, the sewage discharge component 13 extracts the sludge in the lower layer to realize the separate storage of sludge and sewage.
