Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a water conservancy engineering dredging device. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature, thereby achieving the purpose of eliminating harm and promoting benefits. Water conservancy projects contain a large amount of silt, which can raise the water level of rivers. During heavy rains, the water level of rivers cannot be controlled and will overflow from the rivers, causing environmental pollution and economic losses to people. Therefore, it is necessary to clean up the silt in the river regularly to avoid the accumulation of large amounts of silt. At present, most dredging structures are set up on the hull, but the dredging of some small rivers requires onshore equipment.

[0003] A search revealed Chinese Patent Publication No. CN221523685U, which discloses a dredging device for water conservancy projects. The device includes a housing mechanism, an adjustment mechanism, and a dredging mechanism. The adjustment mechanism is located at the upper end of the housing mechanism, and the dredging mechanism is located at the upper end of the adjustment mechanism. The housing mechanism includes a support base, a traveling track, anti-slip strips, a counterweight base, a toolbox, a mounting cover, and a handle.

The dredging mechanism includes a second electric push rod, a second push rod, a third electric push rod, a third push rod, a dredging main unit, a dredging connecting pipe, and a sludge extraction port. Sludge is extracted through the sludge extraction port.

[0004] In order to pump debris such as branches and weeds from the river into the pipe, filter plates are installed at the sludge pumping outlet. However, some debris may get stuck on the filter plates, affecting the efficiency of sludge removal. Utility Model Content

[0005] The purpose of this utility model is to provide a dredging device for water conservancy projects in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A dredging device for water conservancy projects includes a base plate with four casters at the bottom corners and a suction mechanism at the top. The suction mechanism includes a suction assembly and an adjustment assembly.

The adjustment assembly is used to adjust the position of the suction bucket. Two vertical plates are fixedly connected to the bottom of the suction bucket, one in front of the other. Two sets of actuating assemblies are symmetrically arranged between the two vertical plates. Each actuating assembly includes a rotary motor fixedly connected to the front side of the front vertical plate. The output end of the rotary motor is connected to a rotating shaft via a coupling. The rotating shaft is rotatably connected between the two vertical plates. Multiple sets of circumferentially arranged levers are fixedly connected to the outer wall of the rotating shaft. The levers in the two sets of actuating assemblies are arranged crosswise.

[0008] Preferably, a mounting shaft is fixedly connected between the two vertical plates, and a number of equally spaced grating teeth are fixedly connected to the mounting shaft, with the grating teeth located between two adjacent levers.

[0009] Preferably, the length of the lever is greater than the distance between the outer wall of the rotating shaft and the bottom wall of the filter plate, and the extra length of the lever is elastic.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-4As shown, a dredging device for water conservancy projects includes a base plate 1, with four movable wheels 101 at the bottom corners of the base plate 1. A sludge suction mechanism is provided on the top of the base plate 1. The sludge suction mechanism includes a sludge suction assembly, which includes a sludge suction bucket 203. A filter plate 204 is fixedly connected between the inner walls of the sludge suction bucket 203. The sludge suction assembly also includes a counterweight box 2 fixedly connected to the top of the base plate 1. A sludge pump 201 is bolted to one side of the counterweight box 2. An inlet pipe 202 is fixedly connected to the side of the counterweight box 2 away from the sludge pump 201. The other end of the inlet pipe 202 is fixedly connected to the sludge suction bucket 203. The inlet pipe 202 is a corrugated pipe. A sludge conveying chamber communicating with the inlet pipe 202 is opened inside the counterweight box 2. A discharge pipe 205 is connected to the discharge port of the sludge pump 201.

[0025] The sludge suction mechanism includes an adjustment component for adjusting the position of the sludge suction hopper 203. The adjustment component includes a mechanical arm 301 fixedly connected to the top of the counterweight box 2. A mounting plate 302 is fixedly connected to the end of the mechanical arm 301. A support column 303 is fixedly connected to the bottom of the mounting plate 302. The sludge suction hopper 203 is fixedly connected to the bottom of the sludge suction hopper 203. Two support columns 303 are symmetrically arranged at the front and rear. The sludge inlet pipe 202 is located between the two support columns 303 to improve overall stability.

[0026] The bottom of the suction hopper 203 is bolted to two vertical plates 401 arranged one in front of the other. Two sets of actuating components are symmetrically arranged between the two vertical plates 401. The actuating components include a rotary motor 402 bolted to the front side of the front vertical plate 401. The output end of the rotary motor 402 is connected to a rotary shaft 403 through a coupling. The rotary shaft 403 is rotatably connected between the two vertical plates 401. Multiple sets of circumferentially arranged levers 404 are fixedly connected to the outer wall of the rotary shaft 403. The levers 404 in the two sets of actuating components are arranged crosswise. The length of the levers 404 is greater than the distance between the outer wall of the rotary shaft 403 and the bottom wall of the filter plate 204. The extra length of the levers 404 is elastic, which increases the contact area between the levers 404 and the filter plate 204, so that the bottom of the filter plate 204 can be cleaned when the levers 404 rotate.

[0027] A mounting shaft 405 is fixedly connected between two vertical plates 401. Several equally spaced grating teeth 406 are fixedly connected to the mounting shaft 405. The grating teeth 406 are located between two adjacent levers 404. Through the cooperation of the levers 404 and the grating teeth 406, a shearing force is provided for the water plants and other debris wrapped around the levers 404, so that the debris wrapped around the levers 404 can fall off.

[0028] Working principle: In use, the base plate 1 is moved to a suitable position, and the suction bucket 203 is extended into the river channel by the robotic arm 301. The rotary motor 402 is started, and the rotary motor 402 drives the rotary shaft 403 to rotate the lever 404, which pushes the debris under the filter plate 204 to both sides of the suction bucket 203 to prevent the filter plate 204 from clogging. Moreover, the rotation of the lever 404 disperses the silt, making it easier to suck up. When the lever 404 rotates to the position of the grate 406, the cooperation between the lever 404 and the grate 406 provides shearing force for the water plants and other debris wrapped around the lever 404, making it easier for the debris wrapped around the lever 404 to fall off. Then, the silt pump 201 is started, and the silt in the river channel enters the silt inlet pipe 202 through the suction bucket 203 and is then discharged through the silt discharge pipe 205.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
