[0001] This invention relates to the field of channel dredging technology, specifically to a dredging device and method for small-span channels. Background Technology

[0002] After a channel is built and has been in operation for a period of time, silt will usually accumulate at the bottom of the channel. If the silt is not cleaned in time, it will affect the channel's flow capacity and cause flooding when floods occur. Therefore, it is necessary to clean the silt in the channel regularly.

[0003] Currently, the conventional method for cleaning silt in channels involves manually controlling the pipes and suction heads, and simply using pumps to provide power for pumping. This dredging method has the following problems: (1) The pumps currently used have low operating efficiency due to the small operating area; (2) Manual cleaning of the suction heads is required, making automation impossible; (3) The suction heads have a single operating position, requiring constant manual adjustment.

[0011] In the aforementioned small-span channel dredging device, supports are provided on both the front and rear sides of the guide tube, and a motor D is provided on the support. The output shaft of the motor D is connected to the suction head.

[0012] In the aforementioned small-span channel dredging device, a baffle is provided at the lower part of the support base, and a motor B is provided in the baffle. The output shaft of the motor B faces the suction head and is connected to the cleaning disc. A blade is fixedly connected to the end face of the cleaning disc near the suction head.

[0013] In the aforementioned small-span channel dredging device, the guide rail is connected to the control console, which is equipped with a controller and a leveling component.

[0014] A method for using a small-span channel dredging device, the device being used for dredging operations in channels, comprising the following steps:

[0015] S1: Start the electric push rod A to make the moving frame move along the guide rail. The two moving frames on the same side move synchronously through the connection of the guide rod, and realize the adjustment of the distance between the drive wheels on both sides. After adjusting the distance between the drive wheels on both sides, place the support frame above the channel to be cleaned, and place the drive wheels on both sides on the ground on the left and right sides of the channel respectively.

[0016] S2: Start the electric push rod B. The guide rod guides the base plate. The electric push rod B drives the seat to move and adjust the support seat to the sludge removal height. Check if the horizontal component detection device is in a horizontal state. If the support seat is detected to be tilted, it can be adjusted to be horizontal by the electric push rod B.

[0017] S3: Start the electric push rod C and adjust the position of the mobile pump in the support base to the sludge removal position;

[0018] S4: Start motor A, which drives the device to move along the channel via the drive wheel; simultaneously start the mobile pump, using the suction head, hose, guide tube, and drain pipe to extract debris from the channel, achieving dredging while moving; during the dredging process, motor C can be started to adjust the rotation angle of the suction head through gear and guide gear transmission, and motor D can be started to adjust the deflection angle of the suction head, performing all-round dredging operations.

[0019] S5: After sludge removal is complete, adjust the position of the mobile pump by using the electric push rod C so that the suction head contacts the cleaning disc. Start the motor B to make the cleaning disc rotate and clean the surface of the suction head. At the same time, the motor C makes the suction head rotate, thereby completing the cleaning around the suction head.

[0020] More specific usage instructions for the small-span channel dredging device: During water conservancy project construction, when channel cleaning is required, the support base can be placed above the channel to be cleaned, and the drive wheels located on the inner side of the side plate can be simultaneously brought into contact with the ground. After the support base and drive wheels are in place, if it is necessary to adjust the distance between the two sets of drive wheels, the controller located at the front of the control console can be activated, and the two electric push rods A installed in the guide rail can be activated simultaneously to push the two sets of moving frames outwards. The mobile frame moves the guide rods installed on its inner side outwards in sync. Once the guide rods are in the correct position, the electric push rod B installed on the top of the base plate is activated to push the base upwards, adjusting the distance between the drive wheel in the side plate and the base to adjust the height of the support. After the support height is adjusted, the motor A installed on the outer side plate rotates the drive wheel, moving it along the ground around the channel to simultaneously displace the support. During this displacement, the controller and leveling component at the front of the control panel detect whether the device is level. If the support is detected to be tilted, the electric push rod B installed on the top of the corresponding side base plate is activated to push the base upwards to adjust the tilt. In use, the electric push rod C installed in the support adjusts the lateral position of the mobile pump. After the lateral position is adjusted, the mobile pump in the support is activated to use the suction head and discharge mechanism. The system quickly extracts sewage, sludge, and other debris from the channel. During extraction, the motor C, mounted on the top of the mounting plate, drives the gears to rotate, and the rotation angle of the suction head is adjusted through the meshing of the gears and guide teeth. In use, the motor D, mounted on the outside of the bracket, can be used to adjust the deflection of the suction head and hose. Then, the electric push rod C is activated to push the mobile pump to the left, bringing the suction head into contact with the cleaning disc. At this point, the motor B is activated to rotate the cleaning disc, thus cleaning the surface of the suction head.

The controller 4 located at the front of the control console 3 can be activated, and the two electric push rods A6 installed in the guide rail 2 can be activated simultaneously to push the two sets of moving frames 7 outward. The moving frames 7 drive the guide rods 8 installed on their inner sides to extend outward in a synchronized manner.

Guide teeth 28 are fixedly connected in a ring array on the outer circumference of the conduit 27. The guide tooth 28 meshes with the gear 26 for transmission. A bracket 29 is installed on the outer side of the conduit 27. There are two brackets 29, located on the front and rear sides of the outer circumference of the conduit 27, respectively. A motor D30 is installed at the front end of the front bracket 29. A suction head 31 is installed on the rear output shaft of the motor D30, and a flexible hose 32 is installed at the top of the suction head 31. During use, the lateral position of the mobile pump 21 is adjusted by activating the electric push rod C20 installed in the support base 1. After the lateral position of the mobile pump 21 is adjusted, the mobile pump 21 is simultaneously activated to use the suction head 31 and the drain pipe 22 to remove the sewage from the channel. The device can quickly extract water, silt, and other debris. During extraction, the motor C25 mounted on the top of the mounting plate 24 can be activated to drive the gear 26 to rotate. The rotation angle of the suction head 31 can be adjusted by the meshing of the gear 26 and the guide gear 28. When in use, the motor D30 mounted on the outside of the bracket 29 can be activated to adjust the deflection of the suction head 31 and the hose 32. Then, the electric push rod C20 can be activated to push the mobile pump 21 to the left, so that the suction head 31 contacts the cleaning disc 19. At this time, the motor B18 can be activated to drive the cleaning disc 19 to rotate, thereby cleaning the surface of the suction head 31.
