Description

Technical Field

[0001] The present invention relates to the field of water conservancy projects, and in particular to a river channel cleaning device used in water conservancy projects. Background Art

[0002] River cleaning usually involves cleaning the silt on the river surface and below the river channel. Under conventional cleaning conditions, cleaning equipment is usually installed on ships to centrally deal with floating objects or duckweed on the water surface. Larger piles of wooden structures are usually handled by shore or ship-mounted cranes. The underwater silt is mainly handled by pumping out water through cofferdams, or by blowing and stirring the silt deposited on the riverbed into turbid water and letting it flow away with the river water.

[0003] However, current river cleaning equipment is only capable of completing cleaning operations on the river surface, especially during the cleaning process, it can only complete processing operations on light floating objects on the surface, or plants such as duckweed. For heavier long wooden strips, wooden blocks or large structures with certain floating capabilities, such as plastic or foam boxes, conventional processing structures such as self-priming water trash cans are unable to cope with this type of garbage, especially the garbage near water conservancy projects, which are all difficult to handle river garbage structures; at the same time, in the power station or water conservancy gate area under the water conservancy project system, it is also very easy for river silt to accumulate, which will also cause the water level to continue to rise. Therefore, cleaning equipment is also needed to complete the cleaning operation, and the above-mentioned water trash cans or other equipment cannot complete the effect of cleaning both at the same time. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a river channel cleaning device for water conservancy projects.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: The present invention provides a river channel cleaning device for water conservancy projects, comprising a box body and a conveyor belt, wherein the conveyor belt is inclined in a triangular shape, with the side with a smaller angle placed inside the box body, a rear roller shaft is provided at the rear end of the conveyor belt, and a front roller shaft is provided at the front end, the front roller shaft is mounted to the inner wall of the box body, and U-shaped support frames are provided at both ends of the rear roller shaft, a driving motor is provided at one end of the rear roller shaft at the top end of the support frame, and a bearing seat is provided at the other end at the top end of the support frame, and an L-shaped mounting rod is provided at the bottom end of the support frame for mounting to the side of the box body; A front stop door is provided at the front end of the box body, and an inclined groove is provided on the surface of the front stop door.

[0006] As a preferred technical solution of the present invention, the water outlet of the submersible pump is at both sides of the box body, and the surface of the conveyor belt is provided with inclined bars, which are used to increase the friction of the conveyor belt surface.

[0007] As a preferred technical solution of the present invention, the inclined bar has a trapezoidal structure, with the shorter end arranged on the side of the front roller shaft and the higher end arranged on the side of the rear roller shaft, and the rear surface of the inclined bar is also provided with circular teeth. The inclined bar is made of rubber material as a whole, and the upper surface of the inclined bar is provided with circular protrusions.

[0008] As a preferred technical solution of the present invention, the front door is provided with a fixed plate on the upper side of the inclined groove, a telescopic rod is provided on the inner side of the fixed plate, and an extension plate is installed at the bottom end of the telescopic rod, wherein the telescopic rod is used to extend and push the extension plate to cover the surface of the inclined groove.

[0009] As a preferred technical solution of the present invention, a torsion shaft is provided on the surface of the fixing plate, a mask cover is provided on the surface of the torsion shaft, and a camera is provided at the bottom end of the mask cover.

[0010] As a preferred technical solution of the present invention, the support frame and the box body are connected by an L-shaped mounting rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1: The present invention uses a box body and a conveyor belt to allow floating garbage on the water surface to form an external-inward flow state through the height difference between the inside and outside of the box body, so that lighter floating garbage can enter and be concentrated from the conveyor belt to the shore for processing.

[0012] 2: When dealing with heavier or wider floating objects, the present invention can directly dismantle the front door, and use the suction of the submersible pump and the suction port to adsorb the wide floating objects to the nearby area, and then transport them to a certain place for centralized processing through the conveyor belt. In addition, the inclined bars and circular teeth provided in the transportation process can well fix the large floating objects to prevent them from sliding to the outside.

[0013] 3: The present invention can also be based on the improvement of the submersible pump, with the water outlet facing downward, so that the jet of water can flush the silt on the riverbed, allowing the silt on the riverbed to be blown into turbid water and flow away with the river water, thereby reducing the degree of silt deposition.

A suction port 101 is provided on the bottom side of the interior of the box body 1. The suction port 101 is close to the conveyor belt 2, and the suction port 101 is flat. The bottom end of the suction port 101 is connected to a submersible pump 102, and the water outlet of the submersible pump 102 is located on the outside of the box body 1.

[0017] The water outlet of the submersible pump 102 is at both sides of the box body 1 , and the surface of the conveyor belt 2 is provided with inclined strips 4 , which are used to increase the friction force on the surface of the conveyor belt 2 .

[0018] The tilting bar 4 has a trapezoidal structure, with the lower end arranged on the side of the front roller shaft 202 and the higher end arranged on the side of the rear roller shaft 201. The rear surface of the tilting bar 4 is also provided with circular teeth 401. The tilting bar 4 is made of rubber material as a whole, and the upper surface of the tilting bar 4 is provided with a circular protrusion 402.

[0019] A fixed plate 302 is provided on the upper side of the inclined groove 301 of the front door 3, a telescopic rod 303 is provided on the inner side of the fixed plate 302, and an extension plate 304 is installed at the bottom end of the telescopic rod 303, wherein the telescopic rod 303 is used to extend and push the extension plate 304 to cover the surface of the inclined groove 301.

[0020] A torsion shaft 5 is provided on the surface of the fixing plate 302 , a mask cover 501 is provided on the surface of the torsion shaft 5 , and a camera 502 is provided at the bottom end of the mask cover 501 .

[0021] The support frame 203 and the box body 1 are connected by an L-shaped mounting rod 205. The L-shaped mounting rod 205, the front roller shaft 202 and the mask cover 501 can all be removed from the box body 1. The top of the support frame 203 is flat and is used to place the drive motor 204 and the bearing.

[0022] Specifically, the overall structure is as follows Figure 1 As shown, the conveyor belt 2 is driven by a drive motor 204 and a rear roller 201, and can transport garbage from lower places to higher places for centralized storage. The inner side of the inclined strip 4 on the surface of the conveyor belt 2 is hollowed out, and a circular protrusion 401 with a horizontal stripe is provided on the top, which can increase friction when squeezed. At the same time, the circular teeth 401 at the rear end are metal-shaped and can be inserted into the surface of the heavy object to increase the fixing effect when facing heavy or large floating objects. During routine cleaning of the river surface, when facing floating objects such as duckweed or small plastic bags, the submersible pump 102 can be connected to the pipeline and set on both sides of the box 1, facing the water surface, so that both sides can spray water to allow lighter floating objects to be concentrated in front of the box 1, and the U-shaped support frame 203 can be installed on a boat, an unmanned operation boat or a river bank, and the lower part of the box 1 is immersed in the river water to form a routine treatment; when working, since the water flow into the inclined groove 3 set by the front baffle 3 is limited, the inclined groove 3 is set at the water surface, so the submersible pump 102 can lower the water level inside the box body 1 according to demand, so that the water level can be lowered to the lowest point of the conveyor belt 2. Since the suction port 101 is set near the conveyor belt 2, the floating garbage will also approach the conveyor belt 2 due to the suction force until it is moved upward by the conveyor belt 2 to the outside of the box body 1 for centralized storage and subsequent processing, such as in a storage box on the shore or on a ship; since the front door 3 is further provided with a fixed plate 302, the extension plate 304 controlled by the inner telescopic rod 303 can block the water flow entering the inclined groove 301 size, and directly close the water flow at the inclined groove 301, and a spring-structured torsion shaft 5 is also provided on the side of the fixed plate 302, and a camera 502 is provided on the mask cover 501 of the torsion shaft 5. The camera 502 and the telescopic rod 303 are connected to the drive motor 204, and the drive motor 204 is connected to the external power supply; under the control scheme, if it is set up on the shore, the entire equipment can be started intermittently through the equipment cabinet connected separately to the drive motor 204 and the PLC logic chip under the control unit. That is, when it is not turned on, the extension plate 304 is lowered and the entire device is in a dormant state. After starting, the extension plate 304 is raised, and the drive motor 204, the camera 502 and the submersible pump 102 are all in operation until the time period ends. If it is on a boat, it can be connected to a control unit based on an MCU chip, and the direction of the boat or unmanned boat can be determined through manual control and the shooting of the camera 502. When the unmanned boat is equipped with a better camera, the mask cover 501 can be closed downward until it is buckled on the fixed plate 302. Figure 6 The groove can be.

[0023] When facing heavier floating objects, the front baffle 3 can be directly disassembled from the box body 1, and the U-shaped support frame 203 can be installed on the processing vessel. In general, since river siltation and other phenomena usually occur when heavier floating objects appear, a pressurizing structure can be set at the submersible pump 102, such as a Laval pipe or other pump-type pressurizing equipment and structure at the water outlet to increase the water inlet pressure, etc., and the drainage of the submersible pump 102 is downward; when working, the strong suction force formed will suck a large amount of river water from the suction port 101, and heavier floating objects such as wood or foam will be sucked out. For structures such as boxes and plastic foam, the suction force and the propulsion force of the ship will pull floating objects closer to the conveyor belt 2. Heavier objects have buoyancy in water, while one side of the front roller 202 is always submerged in water. When it contacts the conveyor belt 2, the circular teeth 401 will first penetrate into the surface of the object, pulling the floating object out of the water as a whole. After being pulled out, due to the lack of buoyancy, the hollow inclined bar 4 is pressed downward until the top surface of the inclined bar 4 is concave downward, and the concave and convex circular protrusions 402 generate greater friction, so that the conveyor belt 2 can continuously transport river garbage from the inside of the box 1 to the outside; At the same time, because the submersible pump 102 increases the pump force and water outlet pressure, a jet effect will be generated underwater. When the extension pipe is installed to the lower layer of the river channel, the jet at the pump of the pipeline will continuously blow the silt into turbid water, so that the silt can be lifted over a larger area and continuously transported away with the water flow.

[0024] If a cofferdam needs to be set up in the river channel and the river channel silt is dug out based on the cofferdam, the conveyor belt 2 structure can be used to transport the silt to the shore when the silt is dug out.

[0025] Its overall structure is simple, easy to install and operate, and can adapt to use in different environments. While cleaning the garbage on the river surface, it can also complete the underwater silt treatment by adding other equipment. In the normal use process, it can form an intermittent treatment of floating objects on the river surface, such as leaves, catkins and other garbage, without the need for repeated manual care.

[0026] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
