Description

Technical Field

[0001] This invention relates to the field of drainage dredging technology, specifically to a drainage dredging device. Background Technology

[0002] Drainage pipes and channels, also known as drainage channels, are a general term for pipes and channels that collect, transport, and discharge rainwater and various types of sewage. They can be open or closed. Those built along the ground are called "open ditches," "sunny ditches," or "open channels"; those buried underground are called "drainage pipes," "covered pipes," or "underground ditches." The cross-section of the channels can be rectangular, arched rectangular, trapezoidal, or horseshoe-shaped, etc. The pipes are usually prefabricated circular pipes, while the cross-section of the ditches is mostly rectangular or trapezoidal.

[0003] Due to long-term use, drainage ditches inevitably accumulate debris at the bottom. This debris affects the use of the drainage ditches and may even block them, rendering them unable to function. Over time, the debris will accumulate more and more until both sides of the drainage ditches are also blocked. At the same time, during the use of outdoor drainage ditches, larger debris (such as tree branches) may pass through the channel, which may block the drainage ditches in a short period of time. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a drainage ditch dredging device that has the advantages of filtering large debris in the drainage ditch, cleaning debris accumulated at the bottom of the drainage ditch to prevent blockage, and facilitating the cleaning of debris on both sides of the drainage ditch. It solves the problems of debris inevitably accumulating at the bottom and sides of the drainage ditch after long-term use, affecting the use of the drainage ditch, and the presence of large debris inside outdoor drainage ditches, which also affects the use of the drainage ditch.

[0006] (II) Technical Solution

The shell has circular holes of a size and number adapted to the fan blades inside. The limiting member has through holes of a size adapted to the driven member inside. A limiting block is fixedly connected to one side of the shell. The limiting block has through holes of a size adapted to the filter screen inside. A filter screen is disposed inside the limiting block. Two opposing fixing blocks are fixedly connected inside the shell. A small hole of a size adapted to the fan blades is opened at the center of each fixing block. Two opposing fan blades are hinged inside each fixing block. One end of each fan blade is sized to match the small hole on the fixing block, and the fan blade size is adapted to the circular hole inside the shell. Two opposing rotating blocks are fixedly connected to the end of each fan blade away from the fixing block. The size of the rotating block at the end away from the fan blade is sized to match the through hole on the wedge. Two opposing rotating blocks are fitted with D-shaped grooves. Two opposing wedges are provided at the ends of the two opposing rotating blocks away from the fan blades. One side of the wedge has a D-shaped groove with a size that matches the rotating block, and the other side has a triangular groove with a size that matches the locking block. The dimensions of both ends of the wedge are matched with the through holes on the positioning blocks. Two opposing positioning blocks are sleeved on the outer sides of both ends of the wedge. The positioning blocks have through holes with a size that matches the wedge. Two axisymmetric transverse friction members are fixedly connected below the wedge. Two axisymmetric driven members are locked inside the limiting member. One end of the driven member is matched with the through hole on the limiting block, and the other end has a round hole with a size that matches the locking block. A locking block is locked inside the end of the driven member away from the limiting member. One end of the locking block is matched with the round hole on the driven member, and the other end is matched with the triangular groove on the wedge. Two axisymmetric vertical friction members are fixedly connected to the opposite sides of the two axisymmetric driven members.

[0008] Preferably, the fan blade is disposed inside the outer casing, and the end of the positioning block away from the wedge block is fixedly connected to the outer casing.

[0009] Preferably, the end of the limiting member away from the driven member is fixedly connected to the outer shell, and the end of the locking block away from the driven member is locked onto the wedge block.

[0010] Preferably, two axisymmetric telescopic components are fixedly connected inside one end of the track. The telescopic components are connected to the power output terminal of the external motor. Two opposing positioning rings are fixedly connected to the end of the telescopic components away from the track. The positioning rings have through holes with dimensions adapted to the roller shaft.

[0011] Preferably, a roller is inserted inside the positioning ring, the dimensions of the two ends of the roller are adapted to the through holes opened inside the positioning ring, the dimensions of the roller are adapted to the distance between the two tracks, and two opposing rotating wheels are fixedly connected to the two ends of the roller. The rotating wheels mesh with the limiting blocks, and the limiting blocks are provided on the outer side of the rotating wheels.

[0012] Preferably, the track is fixedly connected to the limiting block, and the positioning ring is disposed inside the other end of the track.

[0013] Preferably, the limiting block is fixedly connected to the limiting block on the side away from the rotating wheel.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a drainage ditch dredging device, which has the following beneficial effects:

[0016] 1. This drainage ditch dredging device is installed inside the drainage ditch by workers. When water flows through, it passes through a filter screen and enters the device. The filter screen filters out larger debris in the water. When the water flows through the filter screen to the fan blades, the fan blades rotate under the action of the water flow, which in turn drives the rotating block fixedly connected to it to rotate around the connection point with the fan blades. At this time, one end of the rotating block is engaged with the wedge, which moves along the trajectory of the D-shaped groove on the wedge. This causes the wedge to reciprocate horizontally under the action of the rotating block, which in turn drives the vertical friction component fixedly connected to the wedge to move, thus cleaning the debris accumulated at the bottom of the drainage ditch and preventing the accumulation of debris, thereby achieving the purpose of cleaning the debris accumulated at the bottom of the drainage ditch.

[0017] 2. This drainage ditch dredging device uses a rotating block to drive a wedge block. At this time, a locking block that is engaged in the triangular groove on the other side of the wedge block will move under the action of the wedge block, thereby driving the driven part to move. Under the combined action of the limiting part and the locking block, the driven part makes a vertical reciprocating motion, thereby driving the horizontal friction part that is fixedly connected to it to make a reciprocating motion, thereby achieving the purpose of cleaning up the debris on both sides of the drainage ditch.

[0018] 3. This drainage ditch dredging device works by having the external motor turned on by the staff. When the debris filtered on the screen affects the device's operation, the telescopic component is activated, causing it to retract. This, in turn, drives the positioning ring to move inside the track. As the positioning ring moves, the roller also moves horizontally. During this horizontal movement, the roller starts to rotate due to the action of the rotating wheel and the limiting block meshing with it, cleaning the debris on the surface of the screen. This achieves the purpose of cleaning the debris accumulated on the surface of the screen due to long-term use. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] Please see Figure 1 , Figure 2 and Figures 4 to 7 A drainage ditch dredging device includes a housing 101. The housing 101 has round holes of a size and number that are adapted to the fan blades 105. The housing 101 defines the position of structures such as the limiting block 102 and the fixing block 104, and provides support for these structures.

[0030] A limiting block 102 is fixedly connected to one side of the outer shell 101. The limiting block 102 has a through hole with a size that matches the filter screen 103. The limiting block 102 limits the position of the filter screen 103, the limiting block 306 and the track 301.

[0031] The limiting block 102 is equipped with a filter screen 103, which filters out larger debris in the drainage channel water flow. The outer shell 101 is fixedly connected to two opposing fixing blocks 104. The fixing blocks 104 have a small hole at the center that matches the size of the fan blade 105, and the fixing blocks 104 limit the position of the fan blade 105.

[0032] The fixed block 104 has two opposing fan blades 105 hinged inside. The fan blades 105 are located inside the outer shell 101. The size of one end of the fan blade 105 is adapted to the small hole opened on the fixed block 104, and the size of the fan blade 105 is adapted to the round hole opened inside the outer shell 101. The fan blade 105 will rotate under the action of the water flowing inside the drainage channel, thereby driving the rotating block 106 fixedly connected to it to rotate.

[0033] Two opposing rotating blocks 106 are fixedly connected to the end of the fan blade 105 away from the fixed block 104. The size of the end of the rotating block 106 away from the fan blade 105 is adapted to the D-shaped groove opened on the wedge block 107. The rotating block 106 rotates with the connection point with the fan blade 105 as the fulcrum under the action of the fan blade 105, so that the wedge block 107 moves under the action of the rotating block 106 that is engaged in the D-shaped groove inside it.

[0034] Two opposing rotating blocks 106 are provided with two opposing wedges 107 at the ends away from the fan blades 105. One side of the wedge 107 has a D-shaped groove with a size that matches the rotating block 106, and the other side has a triangular groove with a size that matches the locking block 203. The dimensions of both ends of the wedge 107 match the through holes opened on the positioning block 108. The wedge 107 defines the position of the rotating block 106 and the locking block 203. Under the action of the rotating block 106, the wedge 107 performs a horizontal reciprocating motion on the positioning block 108, thereby driving the transverse friction member 109 and the locking block 203 to move.

[0035] Two opposing positioning blocks 108 are sleeved on the outer sides of both ends of the wedge 107. The end of the positioning block 108 away from the wedge 107 is fixedly connected to the outer shell 101. The positioning block 108 has a through hole with a size that matches the wedge 107. The positioning block 108 defines the position and movement trajectory of the wedge 107.

[0036] Two axisymmetric transverse friction elements 109 are fixedly connected to the lower part of the wedge block 107. The transverse friction elements 109 reciprocate in the horizontal direction under the action of the wedge block 107, thereby contacting the bottom of the drainage ditch and cleaning the debris accumulated at the bottom of the drainage ditch.

[0037] Example 2

[0038] Please see Figure 1 , Figure 2 and Figures 4 to 7 A drainage ditch dredging device includes a limiting member 201. The end of the limiting member 201 away from the driven member 202 is fixedly connected to the outer shell 101. The limiting member 201 has a through hole with a size adapted to the driven member 202. The limiting member 201 limits the position and movement trajectory of the driven member 202.

[0039] The limiting member 201 has two axisymmetric driven members 202 inside. One end of the driven member 202 is adapted to the through hole on the limiting block 102, and the other end has a round hole adapted to the size of the locking block 203. The driven member 202 limits the position of the locking block 203. Under the combined action of the wedge block 107, the locking block 203 and the limiting member 201, the driven member 202 performs a reciprocating motion in the vertical direction, thereby driving the vertical friction member 204 to move.

[0040] A locking block 203 is engaged inside the end of the driven member 202 away from the limiting member 201. The end of the locking block 203 away from the driven member 202 is engaged with the wedge block 107. One end of the locking block 203 is adapted to the circular hole opened on the driven member 202, and the other end is adapted to the triangular groove opened on the wedge block 107. The locking block 203 limits the position of the driven member 202. Under the action of the wedge block 107, the locking block 203 moves inside the triangular groove opened on the wedge block 107, and thus cooperates with the limiting member 201, so that the driven member 202 performs a vertical reciprocating motion.

[0041] Two axisymmetric driven members 202 are fixedly connected to two axisymmetric vertical friction members 204 on their opposite sides. The vertical friction members 204 reciprocate in the vertical direction under the action of the driven block, thereby continuously contacting the two sides of the drainage ditch and clearing the debris accumulated on the two sides of the drainage ditch.

[0042] Example 3

[0043] Please see Figure 1 ,to Figure 3 and Figure 6 A drainage ditch dredging device includes a track 301, which is fixedly connected to a limiting block 102. The track 301 has a through hole with a size that matches the positioning ring 303. The track 301 limits the position of the telescopic member 302 and also limits the movement trajectory of the roller 304.

[0044] Two axisymmetric telescopic members 302 are fixedly connected inside one end of the track 301. The telescopic members 302 are connected to the power output terminal of the external motor. The telescopic members 302 contract under the action of the motor, thereby moving the positioning ring 303 from the end of the track 301 away from the telescopic members 302 to the end close to the telescopic members 302.

[0045] The telescopic component 302 is fixedly connected to two opposing positioning rings 303 at the end away from the track 301. The positioning rings 303 are located inside the other end of the track 301. The positioning rings 303 have through holes with sizes that match the roller 304. The positioning rings 303 limit the position of the roller 304. The positioning rings 303 move inside the track 301 under the action of the telescopic component 302, thereby driving the roller 304 to move.

[0046] A roller 304 is inserted inside the positioning ring 303. The dimensions of both ends of the roller 304 are adapted to the through holes opened inside the positioning ring 303. The dimensions of the roller 304 are adapted to the distance between the two tracks 301. Under the combined action of the positioning ring 303, the roller, and the limiting block 306, the roller 304 moves horizontally inside the track 301. During the displacement process, the roller 304 will rotate continuously, thereby cleaning the debris accumulated on the surface of the filter screen 103 due to long-term use.

[0047] Two opposing rotating wheels 305 are fixedly connected to both ends of the roller shaft 304. The rotating wheels 305 mesh with the limiting block 306. The rotating wheels 305 limit the position of the roller shaft 304. The rotating wheels 305 move under the action of the roller shaft 304. During the movement, they will start to rotate due to the action of the limiting block 306, thereby driving the roller shaft 304 to rotate.

[0048] A limiting block 306 is provided on the outer side of the rotating wheel 305. The side of the limiting block 306 away from the rotating wheel 305 is fixedly connected to the limiting block 102. The size of the limiting block 306 is adapted to the groove opened on the rotating wheel 305. Under the joint action of the limiting block 306 and the rotating wheel 305, the roller 304 will rotate during the movement to clean the dirt on the surface of the filter screen 103.

[0049] Working process and principle: Please refer to Figures 1 to 7 A drainage ditch dredging device is provided. When workers place the device inside the drainage ditch, water flows through the filter screen 103 into the device. The filter screen 103 filters out larger debris in the water. When the water flows through the filter screen 103 to the fan blade 105, the fan blade 105 rotates under the action of the water flow, which in turn drives the rotating block 106 fixedly connected to it to rotate around the connection point with the fan blade 105. At this time, one end of the rotating block 106 is engaged with the wedge 107 and moves along the trajectory of the D-shaped groove on the wedge 107. This causes the wedge 107 to reciprocate horizontally under the action of the rotating block 106, which in turn drives the vertical friction member 204 fixedly connected to the wedge 107 to move, thus cleaning the debris accumulated at the bottom of the drainage ditch and preventing the accumulation of debris.

[0050] By rotating block 106, wedge block 107 is driven to move. At this time, the locking block 203, which is locked in the triangular groove on the other side of wedge block 107, will move under the action of wedge block 107, thereby driving driven member 202 to move. Under the combined action of limiting member 201 and locking block 203, driven member 202 to perform vertical reciprocating motion, thereby driving transverse friction member 109 fixedly connected to it to perform reciprocating motion.

[0051] When the external motor is turned on by the staff, and the debris filtered on the filter screen 103 affects the use of the device, the telescopic component 302 will be activated, causing the telescopic component 302 to retract, thereby driving the positioning ring 303 to move inside the track 301. As the positioning ring 303 moves, the roller 304 will also move horizontally. During the horizontal movement, the roller 304 will start to rotate due to the action of the rotating wheel 305 and the limiting block 306 that meshes with the rotating wheel 305, thus cleaning the debris on the surface of the filter screen 103.

[0052] In summary, this drainage ditch dredging device, when placed inside the drainage ditch by workers, allows water to flow through it. The water flows into the device via the filter screen 103, which filters out larger debris. As the water flows from the filter screen 103 to the fan blade 105, the fan blade 105 rotates under the action of the water flow, thereby driving the rotating block 106, which is fixedly connected to it, to rotate around the connection point with the fan blade 105. At this time, one end of the rotating block 106, which is engaged with the wedge block 107, moves along the trajectory of the D-shaped groove on the wedge block 107. This causes the wedge block 107 to reciprocate horizontally under the action of the rotating block 106, thereby driving the vertical friction member 204, which is fixedly connected to the wedge block 107, to move. This cleans up the debris accumulated at the bottom of the drainage ditch and prevents the accumulation of debris, thus achieving the purpose of cleaning up the debris accumulated at the bottom of the drainage ditch.

[0053] By rotating block 106, wedge block 107 is driven to move. At this time, locking block 203, which is engaged in the triangular groove on the other side of wedge block 107, will move under the action of wedge block 107, thereby driving driven member 202 to move. Driven member 202 will reciprocate vertically under the combined action of limiting member 201 and locking block 203, thereby driving transverse friction member 109, which is fixedly connected to it, to reciprocate, thereby achieving the purpose of cleaning debris on both sides of the drainage ditch.

[0054] When the external motor is turned on by the staff, and the debris filtered on the filter screen 103 affects the use of the device, the telescopic component 302 will be activated, causing the telescopic component 302 to retract. This will drive the positioning ring 303 to move inside the track 301. As the positioning ring 303 moves, the roller 304 will also move horizontally. During the horizontal movement, the roller 304 will start to rotate due to the action of the rotating wheel 305 and the limiting block 306 that meshes with the rotating wheel 305, thus cleaning the debris on the surface of the filter screen 103, thereby achieving the purpose of cleaning the debris accumulated on the surface of the filter screen 103 due to long-term use.
