Description

Technical Field

[0001] This invention relates to the field of river dredging technology, specifically to a river silt removal device for water conservancy projects. Background Technology

[0002] River silt refers to unconsolidated, soft, fine-grained or extremely fine-grained soil deposited in still or slow-flowing water environments through physicochemical and biochemical processes. It is a relatively recent sediment. Accumulated river silt can impair the normal functioning of various river systems, including flood control, drainage, irrigation, water supply, and navigation. Therefore, river silt removal is necessary to restore the normal function of the river.

[0003] Referring to a Chinese patent, a river silt cleaning device (publication number: CN112982527A, publication date: 2021-06-18), this patent solves the problem that after the silt is stirred up, a large amount of silt flows downstream with the river water, causing sedimentation in the downstream riverbed and resulting in low silt removal efficiency. However, this patent still has the following shortcomings: after the silt is pumped up, it often contains some stones and garbage. If these are not screened and removed, they are very easy to clog and jam the silt pump and silt conveying pipe. In response, we propose a river silt cleaning device for water conservancy projects to solve the above problems. Summary of the Invention

[0015] Beneficial effects

[0016] This invention provides a device for cleaning river silt in water conservancy projects. Compared with the prior art, it has the following advantages:

[0017] (1) The river silt cleaning device for water conservancy projects, through the setting of the reciprocating dredging component, uses the reciprocating movement of the dredging rod to dredge and spread the silt. With the dilution of water, the silt is filtered into the silt receiving box, leaving the stones and garbage in the silt in the silt receiving box, thus achieving the screening of stones and garbage in the silt and avoiding the stones and garbage in the silt from clogging the pipes and pumps. Through the setting of the cleaning component and the plug-in mechanism, after the plug rod is inserted into the plug hole, the cleaning component and the moving block are plugged in and connected in parallel, realizing the synchronous movement of the cleaning component and the reciprocating dredging component. Thus, the stones and garbage in the silt screening box are cleaned out by the cleaning plate. When the cleaning component is not needed, the horizontal bar is pulled up and rotated into the horizontal groove one, realizing plug-and-play, convenient operation and high flexibility.

[0018] (2) The river silt cleaning device used in water conservancy projects realizes the automatic dredging mechanism to dredge the silt from the river bottom and throw it into the sludge box. The degree of automation is high. Compared with the silt pump, it can avoid the silt pump from getting stuck.

[0019] (3) The river silt cleaning device used in water conservancy projects can accelerate the removal of silt from the silt storage box by setting up the silt pushing component, which can facilitate the quick removal of silt and improve work efficiency. Attached Figure Description

[0032] The automated dredging mechanism 2 includes a rotating shaft 21 rotatably connected between two floating plates 1 on opposite sides. Two fixed wheels 22 are fixed on the rotating shaft 21, and multiple dredging rods 23 are arranged in a circumferential array on the outer surface of the two fixed wheels 22.

[0033] Multiple dredging rods 23 are each fixed to one end with a dredging arc plate 24. By rotating the dredging rods 23, the dredging arc plate 24 can dredge the silt in the river channel and throw it into the silt box 3. A motor 25 is fixed to the top of one of the floats 1. The motor 25 is controlled by an external switch and electrically connected to an external power source. The output end of the motor 25 and the outer surface of the rotating shaft 21 are both fixed with pulleys 26. The two pulleys 26 are connected by a belt 27.

[0035] Example 2

[0036] Based on Example 1, see Figures 4-6As shown, the reciprocating guiding assembly 15 includes two mounting plates 151 fixed on one side of the sludge screening box 3. A lead screw 152 is rotatably connected between the opposite sides of the two mounting plates 151. A motor 153 is fixed on one side of one of the mounting plates 151. The motor 153 is a three-phase asynchronous motor that can rotate in both directions. The motor 153 is controlled by an external switch and is electrically connected to an external power supply. One end of the lead screw 152 passes through the mounting plate 151 and extends to the outside of the mounting plate 151. The output end of the motor 153 is fixed to one end of the lead screw 152 through a coupling. A moving block 154 is slidably connected to one side of the sludge screening box 3.

[0037] One end of the lead screw 152 passes through the movable block 154 and extends to the outside of the movable block 154. The outer surface of the lead screw 152 is threadedly connected to the inner surface of the movable block 154. Two side plates 155 are fixed on one side of the movable block 154. A connecting plate 156 is fixed on one side of each of the two mounting plates 151. A switch button 157 is provided on one side of one of the connecting plates 156.

[0038] Another connecting plate 156 has a switch button 158 on one side. Touching the switch button 157 and the switch button 158 controls the forward and reverse rotation of the motor 153. The two side plates 155 are in contact with and pressed against the sides of the switch button 157 and the switch button 158 respectively. An L-shaped plate 159 is fixed to the top of the moving block 154. Multiple guide rods 1510 are fixed to the bottom of the L-shaped plate 159. The guide rods 1510 can guide and spread the silt. The bottom ends of the multiple guide rods 1510 extend into the interior of the sludge screening box 3. By setting the reciprocating guide component 15, the silt is guided and spread by the back-and-forth movement of the guide rods 1510. With the dilution of water, the silt is filtered into the sludge receiving box 6, leaving the stones and garbage in the silt in the sludge receiving box 6. This achieves the screening of stones and garbage in the silt and avoids the stones and garbage in the silt clogging the pipes and pump body.

[0039] The cleaning assembly 16 includes a cleaning plate 161 that is slidably connected between the inner walls of the sieving box 3, and a connecting rod 162 is fixed to the top of the cleaning plate 161.

[0040] The insertion mechanism 17 includes an insertion hole 171 opened on one side of the top of the movable block 154, and the bottom end of the connecting rod 162 is slidably connected to the insertion rod 172. The bottom end of the insertion rod 172 passes through the insertion hole 171 and extends into the interior of the insertion hole 171.

[0041] The top end of the insert rod 172 passes through the connecting rod 162 and extends into the interior of the connecting rod 162. A vertical groove 173 is formed on one side of the connecting rod 162, and a first horizontal groove 174 and a second horizontal groove 175 are formed on the same side. Both the first horizontal groove 174 and the second horizontal groove 175 communicate with the vertical groove 173. A horizontal rod 176 is fixed to one side of the insert rod 172. One end of the horizontal rod 176 passes through the connecting rod 162 and extends to the outside of the connecting rod 162. The outer surface of the horizontal rod 176 is connected to the vertical groove 173, the first horizontal groove 174, and the second horizontal groove 175. The inner surface of 175 is slidably connected. Through the setting of the cleaning component 16 and the plug-in mechanism 17, after the plug rod 172 is inserted into the plug hole 171, the cleaning component 16 and the moving block 154 are plugged and connected in parallel, realizing the synchronous movement of the cleaning component 16 and the reciprocating dredging component 15. Thus, the stones and garbage in the sieve box 3 are cleaned out by the cleaning plate 161. When the cleaning component 16 is not needed, the crossbar 176 is pulled up and rotated into the cross groove 174. It realizes plug-and-play, convenient operation and high flexibility.

[0042] Example 3

[0043] This embodiment is obtained by combining Embodiment 1 and Embodiment 2, see [link / reference]. Figures 1-8As shown, during operation, motor 25 is started, causing the rotating shaft 21 to rotate. The rotating shaft 21 then drives the dredging rod 23 and the dredging arc plate 24 to rotate. During the rotation of the dredging arc plate 24, the silt from the river channel is dredged up and thrown into the silt screening box 3. The water pump inside the water storage tank 12 is then started, causing water to be discharged into the water storage tank 12 from the outlet pipe 14. The water further dilutes the silt. Motor 153 is then started, causing the lead screw 152 to rotate. Simultaneously, the lead screw... Rod 152 drives moving block 154 forward. Moving block 154 further drives L-shaped plate 159 and guide rod 1510 forward. When side plate 155 of the moving block touches switch button 158, switch button 158 causes motor 153 to reverse, further causing moving block 154 to move backward. When the other side plate 155 touches switch button 157, switch button 157 drives motor 153 to rotate forward, and moving block 154 moves forward again, thus achieving drainage. The rod 1510 moves back and forth, guiding the silt. Diluted by water, the silt and water fall through the screen holes 4 into the mud receiving box 6, while stones and debris in the silt remain in the screen box 3. Further rotation of the horizontal rod 176 causes it to rotate 90 degrees in the horizontal groove 174 and be positioned in the vertical groove 173. Further pulling down the horizontal rod 176 causes it to move the insertion rod 172 downwards, further inserting the insertion rod 172 into the insertion hole 171. Further rotation of the horizontal rod 176... The crossbar 176 rotates into the second cross groove 175 to achieve a limit position. At this time, the moving block 154 moves while driving the connecting rod 162 and the cleaning plate 161 to move, opening the box door 5. When the cleaning plate 161 moves forward, it pushes out stones and garbage, achieving cleaning. The mud pump 11 is then started, causing it to pump the water-containing sludge in the mud receiving box 6 into the mud storage box 7. The box door 8 is then opened, and the cylinder 181 is started, causing it to drive the mud pushing plate 182 to accelerate the pushing out of the sludge, achieving cleaning.

[0045] The embodiments of the invention have been described in detail above, but the content described is only a preferred embodiment of the invention and should not be considered as limiting the scope of the invention. All equivalent changes and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
