Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water conservancy project silt removal device. Background Art

[0002] In water conservancy projects, the main purpose of dredging is to ensure the normal operation and safety of the river, improve the flood-carrying capacity of the river, improve the water quality of the river, protect the ecological environment of the river, and at the same time improve the beauty of the river. Therefore, in water conservancy projects, dredging is a very important task that needs to be carried out regularly.

[0003] Existing dredging devices are usually composed of a suction pipe, a suction head, a vacuum pump, a mud storage box, etc. When working, the silt can be sucked into the mud storage box, and then the silt is transported to a designated treatment site for treatment by a transport vehicle. However, due to the complex environment in the river channel, aquatic plants, garbage or stones in the river channel will be sucked into the device during the silt suction, causing blockage and affecting the normal operation of the device. Utility Model Content

[0004] The utility model aims to provide a hydraulic engineering silt removal device, which can filter out aquatic plants, garbage, stones and other debris when sucking underwater silt, thereby solving the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0006] A desilting device for a water conservancy project comprises a water pump, a filter assembly and a second filter box.

[0007] The filter assembly includes a connecting seat and a motor, a first connecting cylinder is installed on the outer surface of the connecting seat, and the water pump is connected to the first connecting cylinder on the connecting seat through a connecting pipe;

[0008] A second connecting tube is installed on one side of the connecting base away from the first connecting tube, and a suction head is installed on the other end of the second connecting tube;

[0009] A third connecting tube is installed at one end of the connecting seat, and the connecting seat is connected to the second filter box through the third connecting tube;

[0010] A base is installed at one end of the connecting seat away from the third connecting cylinder, the motor is installed on the base, a threaded rod is fixedly installed on the motor along the output shaft direction, and the threaded rod extends into the connecting seat;

[0011] A guide rod is symmetrically installed at one end of the base away from the motor;

[0012] A sliding plate is arranged in the connecting seat, a through threaded hole is opened at the axis of the sliding plate, and through sliding holes are symmetrically opened on both sides of the connecting seat away from the axis.

[0013] The sliding plate is threadedly mounted on the threaded rod through the threaded hole, and the sliding plate slides on the guide rod through the sliding hole.

[0014] It can be seen that when the silt removal and mud suction work is in progress, a water pump is set up to drive the suction head to suck the silt in the riverbed. The suction head is connected to the second connecting tube on one side of the connecting seat. When the silt is sucked into the connecting seat, the garbage, stones or aquatic plants are pushed by the sliding plate and fall into the second filter box from the third connecting tube. The sliding plate is threadedly installed on the threaded rod on the motor through the threaded hole. The sliding plate is sleeved on the guide rod through the sliding hole. When the motor rotates forward or reversely, it drives the sliding plate to reciprocate, thereby cleaning the debris in the connecting seat into the second filter box, and the filtered muddy water flows out from the connecting tube of the first connecting tube.

[0015] Furthermore, the top end of the first filter box is open, and the top end cover of the first filter box is provided with a top cover, and the water pump is fixedly mounted on the top cover.

[0016] A partition is installed in the first filter box, and the partition divides the first filter box into two parts: a mud tank and a filter water tank;

[0017] A geotextile bag is laid in the mud trough, and the top cover presses the geotextile bag at the upper port of the first filter box;

[0018] A penetrating water outlet is provided on the inner side wall of the water filter tank.

[0019] The water pump sucks the filtered muddy water into the mud trough. The muddy water is filtered by the geotextile bag, leaving the mud and sand in the mud trough. The water flows into the filter trough through the gaps on the mud trough and is discharged through the water outlet, achieving the effect of mud and water separation.

[0020] Furthermore, first plug holes are symmetrically opened in pairs at the outer ports of the first filter box, and penetrating second plug holes are symmetrically opened in pairs at the top of the top cover;

[0021] An insert rod is inserted between the second insert hole and the first insert hole.

[0022] The top cover is limited on the first filter box by setting an insertion rod.

[0023] Furthermore, a slide plate is placed on the inner wall end of the second filter box, and a connecting rod is fixedly installed on the top end of the slide plate along the axis thereof.

[0024] A sliding plate is provided, and a connecting rod is fixedly installed at the top of the sliding plate along the axis thereof, and the garbage in the second filter box can be taken out by pulling the sliding plate.

[0025] Furthermore, water leakage grooves are arranged at equal intervals on the skateboard.

[0026] Since the garbage or aquatic plants in the second filter box contain a large amount of water, the water is filtered out by setting a drainage trough, which saves more effort when pulling the skateboard.

[0027] Furthermore, a handle is fixedly mounted on one end of the connecting rod away from the skateboard, and anti-slip grooves are arranged on the handle.

[0028] Providing a handle makes it more convenient for the user to pull the skateboard. BRIEF DESCRIPTION OF THE DRAWINGS
