Description

Technical Field

[0001] The utility model relates to the technical field of channel desilting, in particular to a water conservancy project channel desilting device based on water flow drive. Background Art

[0002] A canal is a man-made waterway used to irrigate fields and divert rivers. It can be divided into main canals and branch canals. Main canals and branch canals are usually built with stone or cement.

[0003] During the long-term use of the canal, affected by natural factors, silt and debris often accumulate in the canal, affecting normal water conservancy operations. In the related art, the Chinese patent with the announcement number CN113833045A discloses a canal dredging vehicle, including a vehicle body, a top plate, a grinding wheel device, a mud pump, a master control device, a transmission duct, a cleaning opening and closing plate, a push rod, a changing power wheel, a dredging roller power pipe, a power pipe fixing bracket, a bracket mounting bolt, a front duct, a fender, a fender bracket, a dredging roller shaft, a dredging roller, and a sludge storage box. The top of the vehicle body is fixedly connected to the top plate, and the grinding wheel device is installed at the front end of the top plate. However, due to the geographical environment, long-distance canals usually do not have the ability to supply electricity, which will cause the dredging equipment used to be affected, making it difficult to carry out long-distance dredging operations.

[0004] In order to reduce the power consumption of dredging equipment, a water blocking plate can be set behind the dredging equipment to use the impact force of the water flow to move it, and the silt can be shoveled by the bucket during the displacement process. However, as the silt in front of the dredging equipment continues to increase, the silt will exert resistance on the movement of the dredging equipment, making it difficult for the water flow to continue to drive the dredging equipment, which is not conducive to long-distance dredging operations.

[0005] To solve the above problems, the Chinese patent with announcement number CN220080147U cleans the silt accumulated in front of the dredging equipment by setting a material lifting assembly at the bucket. However, since the material lifting assembly is located in the canal, it is difficult to transfer the silt to both sides of the canal through the material lifting assembly. Summary of the invention

[0039] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0041] See also Figure 1 As shown, a water conservancy project channel silting device based on water flow drive is provided, including a frame 100, a bucket 110 arranged on one side of the frame 100, and a water blocking plate 120 elastically arranged on the other side of the frame 100, wherein the bucket 110 and the water blocking plate 120 are arranged opposite to each other, and a silt lifting assembly 140 for lifting the silt at the bucket 110 upward is arranged in the middle of the bucket 110; the water blocking plate 120 has an initial position and a driving position, and a guide assembly 130 is arranged between the initial position and the driving position; when the bucket 110 is blocked by silt, the water blocking plate 120 uses the force of the flowing water in the water channel 200 to switch from the initial position to the driving position, and drives the guide assembly 130 during the switching process, so that the guide assembly 130 guides the water in the water channel 200 to the silt lifting assembly 140, and uses the impact force of the water flow to impact the silt at the silt lifting assembly 140 to both sides of the water channel 200.

[0042] The vehicle frame 100 is in a "U"-shaped structure with its opening facing downward; a wheel 101 is disposed at one end thereof, the other end is fixedly connected to a bucket 110, and a top plate 102 is fixedly disposed at the top.

[0043] That is to say, when a large amount of silt accumulates and blocks the bucket 110 from moving forward, the water flow is intercepted and the water level is forced to rise to increase the thrust on the water blocking plate 120, so that the water blocking plate 120 can drive the water flow to impact the silt lifting assembly 140 by displacement, thereby impacting the silt at the silt lifting assembly 140 to both sides of the canal 200, thereby realizing the transfer of the silt, and no electricity is consumed in the process.

[0044] like Figure 2-Figure 4As shown, the sludge lifting assembly 140 includes a shell 141 fixedly arranged in the middle of the bucket 110, and the shell 141 is a "U"-shaped structure with an opening facing the front of the bucket 110. A plurality of rollers are rotatably arranged in the shell 141, and a transmission belt 142 is provided for rotating together between the plurality of rollers. A salvage plate 143 is fixedly arranged on the side wall of the transmission belt 142, and one end of the salvage plate 143 is bent upward; guide plates 144 are arranged on both sides of the shell 141, and when the salvage plate 143 moves upward, both ends of the salvage plate 143 contact the end of the guide plate 144; and, the height of the guide plate 144 is higher than the height of the canal 200, and one end of the guide plate 144 protrudes from the side wall of the canal 200. The sludge lifting assembly 140 also includes a driving unit for driving the rollers to rotate.

[0045] like Figure 5 As shown, the guide assembly 130 includes a piston cylinder 131 fixedly arranged on one side of the top plate 102, a piston 132 is slidably arranged in the piston cylinder 131, a connecting rod 133 is arranged between one end of the piston 132 and the side wall of the water blocking plate 120 to connect the two, and a compression spring 134 is arranged at one end of the piston cylinder 131 and the side wall of the water blocking plate 120 to elastically connect the two, when the compression spring 134 is in a normal state, the water blocking plate 120 is in an initial position, and when the compression spring 134 is compressed, the water blocking plate 120 is in a driving position; at the same time, the outer ring of the piston cylinder 131 is provided with a one-way discharge valve 135 and a one-way inlet valve 136 connected to the inside, and the top of the one-way discharge valve 135 is connected to a liquid infusion tube 137. In addition, the one-way inlet valve 136 is preferably arranged at the bottom of the piston cylinder 131, so that the one-way inlet valve 136 contacts the water in the water channel 200 to achieve the effect of absorbing water.

[0046] In some embodiments, one end of the infusion tube 137 is bent above the salvage plate 143 , and the end is arranged downward, so that the water squeezed out by the piston 132 can flow directly into the salvage plate 143 .

[0047] In other embodiments, one end of the infusion tube 137 is connected to a water tank 138 fixedly arranged on the top of the top plate 102, and one end of the water tank 138 is connected to a drainage tube 139, one end of the drainage tube 139 is bent above the salvage plate 143, and the end is arranged downward. In this way, the water squeezed out by the piston 132 will first flow into the water tank 138, be stored in the water tank 138, and then be discharged into the salvage plate 143 through the drainage tube 139.

[0048] Working principle:

[0049] The device is placed inside the canal 200, and the water flowing in the canal 200 drives the water blocking plate 120 to move. At this time, the water blocking plate 120 drives the bucket 110 and the sludge lifting assembly 140 to move through the frame 100, and the bucket 110 moves to shovel the sludge in the canal 200. As the sludge continues to increase, when the sludge blocks the bucket 110, the driving unit drives the roller to rotate, the roller drives the transmission belt 142 to rotate, and the transmission belt 142 rotates to drive the salvage plate 143. During the rotation of the salvage plate 143, it rises from the bottom of the canal 200 to the top of the canal 200, and lifts the sludge at the bucket 110 upward during the rising process.

[0050] At the same time, since the bucket 110 cannot move, the water blocking plate 120 will intercept the water in the water channel 200, causing the water level behind the water blocking plate 120 to continue to rise. As the water level rises, the thrust exerted by the water behind the water blocking plate 120 on the water blocking plate 120 will also increase, forcing the compression spring 134 to start compressing, and at this time the water blocking plate 120 moves from the initial position to the driving position. At the same time, the water blocking plate 120 will also push the piston 132 to move through the connecting rod 133, and the displacement of the piston 132 will squeeze the water inside the piston cylinder 131 into the infusion pipe 137 through the one-way drainage valve 135, and the water in the infusion pipe 137 will enter the water tank 138, and then the water in the water tank 138 will be discharged into the salvage plate 143 through the drainage pipe 139. At this time, under the impact of the water flow, the water in the salvage plate 143 will impact the silt in the salvage plate 143 toward both ends, so that the silt in the salvage plate 143 is impacted into the guide plate 144 and then discharged through the end of the guide plate 144. Since the end of the guide plate 144 protrudes from the side wall of the canal 200, the silt will fall on both sides of the canal 200 when it is discharged through the guide plate 144, thereby preventing the silt from falling into the canal 200 again.

[0051] After the silt is cleaned, the silt in front of the bucket 110 becomes less, and the water flow in the water channel 200 continues to push the water blocking plate 120 to make the equipment move forward. At the same time, the compression spring 134 rebounds to drive the piston 132 to reset. The piston 132 sucks the water flow in the water channel 200 into the piston cylinder 131 through the one-way liquid inlet valve 136.

[0052] In the above, the driving part can use a motor to drive the roller, or it can use a mechanical method to drive it. Figure 6The driving part includes an impeller 150 rotatably arranged on the side wall of the water blocking plate 120, the end of the impeller 150 is coaxially fixedly connected with an impeller shaft 151, one end of the impeller shaft 151 is slidably connected with a universal shaft 152, one end of the universal shaft 152 is fixedly connected with a worm 153, the top of the worm 153 is meshed with a worm wheel 154, one end of the worm wheel 154 is coaxially fixedly connected with a driven shaft 155, and one end of the driven shaft 155 is coaxially fixedly connected with a roller; the outer ring of the universal shaft 152 is rotatably connected with a shaft sleeve 156, and the shaft sleeve 156 is fixedly arranged on one side of the bucket 110.

[0053] Working principle: when the bucket 110 is blocked by silt, part of the water flow blocked by the water blocking plate 120 will flow out through the impeller 150, and push the impeller 150 to rotate during the flow. The rotation of the impeller 150 drives the universal shaft 152 to rotate through the impeller shaft 151. The rotation of the universal shaft 152 drives the worm wheel 154 to rotate through the worm 153. The worm wheel 154 drives the roller to rotate through the driven shaft 155, and the roller can drive the transmission belt 142 to rotate.

[0054] It should be noted that, since the water blocking plate 120 will move, the impeller shaft 151 and the universal shaft 152 are in a sliding connection state. The outer ring of the impeller shaft 151 has a protrusion, and the inner ring of the universal shaft 152 has a groove, so that the impeller shaft 151 can transmit the rotational power to the universal shaft 152.

[0055] Moreover, when there are some obstacles (protruding stones, etc.) that are difficult to move at the bottom of the water blocking plate 120, the bucket 110 will be completely blocked, making it difficult to move forward. To this end, the bottoms of the bucket 110 and the housing 141 are fixedly connected with an elastic plate 111, one end of which is bent toward the front of the bucket 110 to form an adjustment end 112; one side of the water blocking plate 120 is fixedly connected with a push rod 121, one end of which is attached to the side wall of the elastic plate 111. When the water blocking plate 120 is switched from the initial position to the driving position, the water blocking plate 120 pushes the elastic plate 111 to bend through the push rod 121, so that the adjustment end 112 at the end of the elastic plate 111 is in an inclined state, thereby using the inclined state of the adjustment end 112 to pass over the obstacles.

[0056] During dredging, the adjusting end 112 at the end of the elastic plate 111 is attached to the bottom of the canal 200 to shovel up the silt at the bottom of the canal 200. When the adjusting end 112 hits an obstacle, the bucket 110 cannot move forward at this time, and the water blocking plate 120 is pushed by water to move, and during the displacement process, it pushes the push rod 121 to move, and the displacement of the push rod 121 pushes the elastic plate 111 to deform. When the elastic plate 111 is deformed, the adjusting end 112 at the end of the elastic plate 111 will tilt, so that the bottom of the adjusting end 112 is in an inclined state. At this time, the inclined surface at the bottom of the adjusting end 112 will contact the obstacle. Due to the effect of the inclined surface, the friction between the adjusting end 112 and the obstacle is reduced. At this time, driven by the water flow, the bucket 110 can move upward through the inclined surface at the bottom of the adjusting end 112, thereby crossing the obstacle to continue moving forward.

[0057] In summary, when blocked by an obstacle, the driving position of the water blocking plate 120 can drive the bottom of the bucket 110 to deform, thereby changing the structural state of the bottom of the bucket 110, so that the bottom of the bucket 110 passes through the obstacle in an inclined manner, so that the equipment continues to move forward automatically.
