Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, specifically a drainage ditch retaining structure for water conservancy design and its usage method. Background Technology

[0002] Drainage ditches are a type of infrastructure used to manage and control rainfall. They effectively remove rainwater from the surface, reducing surface water accumulation and stress on the surrounding environment and buildings. At the same time, drainage ditches prevent rainwater from accumulating, reducing the risk of damage to buildings, roads, and infrastructure and extending their service life. In farmland, drainage ditches can control soil moisture, prevent excessive soaking, and help maintain soil stability and crop growth.

[0003] Currently, in order to prevent debris from entering the drainage ditch and causing blockage, a mesh screen is usually installed inside the drainage ditch. The mesh screen can filter out debris, thus preventing it from entering the drainage ditch.

[0004] However, since the screen is in a fixed position, when the screen filters debris for a long time, the debris will accumulate on the screen, which will reduce the permeability of the screen and prevent water from entering the drainage ditch, causing the drainage ditch to lose its drainage function.

[0040] A method for using a drainage ditch retaining structure in hydraulic engineering design, wherein the method uses the aforementioned drainage ditch retaining structure in hydraulic engineering design, and the method of use is as follows:

[0041] Step 1: First, install the barrier structure inside the drainage ditch. When the drainage ditch is draining normally, the water will carry debris through the ditch and pass through the barrier structure.

[0042] Step 2: When the water and debris pass through the barrier structure, the water will pass through the conveyor network structure, and the rotating conveyor network structure will sift the debris out of the water.

[0043] Step 3: The screened debris will be transferred to a collection box, and then to a storage box, where it can be cleaned manually at regular intervals.

[0044] The beneficial effects of this invention are as follows:

[0045] 1. The present invention relates to a drainage ditch retaining structure and its usage method for hydraulic design. By setting up a rotating conveyor network structure, when water flow and debris pass through the retaining structure, the water flow passes through the conveyor network structure, and the debris in the water flow is filtered by the conveyor network structure. Then, during the rotation of the conveyor network structure, the debris can be transferred to a collection box, and then transferred to a storage box. This avoids the debris from clogging the drainage ditch for a long time, which would lead to a decrease in the drainage effect of the drainage ditch and cause the drainage ditch to lose its drainage function.

[0046] 2. The drainage ditch barrier structure and its usage method described in this invention, when the threaded rod is rotated in the forward direction, indirectly pushes the two mounting plates away from each other. At the same time, the overall conveyor network structure widens to accommodate the width of the drainage ditch, thus making the barrier structure suitable for drainage ditches of different widths. Simultaneously, pushing the second and third rotating rods upward increases the height of the conveyor network structure, thereby making the barrier structure suitable for drainage ditches of different widths.

[0061] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0062] like Figures 1 to 12 As shown, the present invention provides a drainage ditch retaining structure for hydraulic design and its usage method, which are detailed below:

[0063] Example 1: A drainage ditch retaining structure for hydraulic design, comprising a retaining structure; the retaining structure is installed inside the drainage ditch;

[0064] The barrier structure includes two opposing mounting plates 1; three rotating rods are arranged between the two mounting plates 1, and the three rotating rods are triangularly distributed and rotate on the two mounting plates 1; the three rotating rods rotate clockwise in one direction only.

[0065] The three rotating rods are a first rotating rod 11, a second rotating rod 12, and a third rotating rod 13; the first rotating rod 11 is rotatably mounted on the lower left of two opposing mounting plates 1.

[0066] The second rotating rod 12 is rotatably mounted on the upper right position of the two opposing mounting plates 1; the second rotating rod 12 is rotatably mounted on the lower right position of the two opposing mounting plates 1.

[0067] Each of the three rotating rods has a rotating wheel 14 fixedly connected to both ends; a rotating belt 15 is rotatably connected to the three rotating wheels 14 on the same side, and the rotating belt 15 is triangular in shape under the limitation of the three rotating wheels 14.

[0068] Two conveyor belts 15 are provided with uniformly arranged driven plates 2 on opposite sides, and the two ends of the driven plates 2 are respectively fixedly connected to the close conveyor belts 15;

[0069] Each of the two adjacent driven plates 2 is fixedly connected with a filter screen 3, and the multiple filter screens 3 and the multiple driven plates 2 form a triangular conveyor network structure;

[0070] The mounting plate 1 has a collection mechanism on the right side of the drainage ditch, and the collection mechanism is used to collect debris blocked by the barrier structure;

[0071] In this embodiment, the collection mechanism includes a collection box 4; the collection box 4 is installed above the drainage ditch; the top of the collection box 4 is an open design;

[0072] The side plate of the collection box 4 near the conveyor belt 15 is lower than the side plate of the collection box 4 away from the mounting belt. When the conveyor belt 15 drives the driven plate 2 to rotate, the driven plate 2 does not contact the collection box 4.

[0073] The inner cavity of the collection box 4 is U-shaped; a belt box 41 is fixedly connected to the middle of the collection box 4; a first rotating shaft 42 is rotatably connected inside the collection box 4, and the first rotating shaft 42 passes through the belt box 41; a belt 43 is provided inside the belt box 41, and the belt 43 passes over the first rotating shaft 42, and the other side of the belt 43 extends to the bottom of the collection box 4.

[0074] Two support plates 44 are fixedly connected to the bottom of the collection box 4; a second rotating shaft 45 is rotatably connected between the two support plates 44, and a belt 43 is sleeved on the second rotating shaft 45; turbines 46 are evenly arranged and fixedly connected to the second rotating shaft 45.

[0075] Both sides of the belt box 41 are fixedly connected to the first rotating shaft 42 with spiral blades 47, and the spiral directions of the spiral blades 47 are opposite.

[0076] Storage boxes 48 are installed on both sides of the collection box 4 on the drainage ditch, and the collection box 4 and the storage box 48 are connected; the first rotating shaft 42 extends into the storage box 48 and is rotatably connected to the storage box 48.

[0077] The first rotating shaft 42 extends into one side of the storage box 48, and evenly arranged paddles 49 are fixedly connected to the outer ring surface of the first rotating shaft 42.

[0078] Specifically, during normal drainage, the water flow carries debris within the ditch. When the water carrying debris passes the barrier structure, it impacts the driven plate 2. The water then passes through the filter screen 3 and continues to flow within the ditch. Since the debris flows with the water, it possesses potential energy. When the debris comes into contact with the driven plate 2 and the filter screen 3, it moves to the upper right along the filter screen 3 and the driven plate 2 under their guidance. Simultaneously, the debris pushes the conveyor belt structure to rotate clockwise, which in turn drives the conveyor belt 15 and the rotating rod to rotate. Since the rotating rod rotates clockwise in one direction, the conveyor belt structure will not reverse after rotation. This prevents the debris from being pushed to rotate in the opposite direction by its own weight, thus preventing it from being carried back into the drainage ditch.

[0079] More specifically, as the debris continues to flow to the location of the barrier structure, the debris with potential energy will also push the conveyor network structure to rotate. During the rotation of the conveyor network structure, the debris that was originally located on the conveyor network structure will be moved and brought into the collection mechanism. In this process, by setting up a rotating conveyor network structure, the debris that follows the water flow can be carried out, thereby avoiding the debris from being blocked in the drainage ditch for a long time, which would lead to a decrease in the drainage effect of the drainage ditch itself and cause the drainage ditch to lose its drainage function.

[0080] Furthermore, when debris falls from the conveyor structure, it falls into the collection box 4. Since a second rotating shaft 45 is rotatably connected between the two support plates 44 installed at the bottom of the collection box 4, and a turbine 46 is fixedly connected to the second rotating shaft 45, when water flows through the turbine 46, it will drive the turbine 46 to rotate, and the turbine 46 will drive the second rotating shaft 45 to rotate. At the same time, the second rotating shaft 45 will drive the first rotating shaft 42 to rotate through the belt 43. During the rotation of the first rotating shaft 42, it will drive the spiral blades 47 to rotate. Since the two spiral blades 47 have opposite spiral directions, they can push the debris to move into the storage boxes 48 on both sides. After the debris moves into the storage box 48, since the lever 49 is fixedly connected to the first rotating shaft 42, the first rotating shaft 42 will drive the lever 49 to rotate. The rotating lever 49 will push the debris that has entered the storage box 48 to the other side of the storage box 48, thereby preventing the debris from accumulating at the position of the spiral blades 47. As the amount of debris in the storage box 48 increases, it can be cleaned manually at regular intervals.

[0081] Example 2: The second rotating rod 12 and the third rotating rod 13 point to one side of the two mounting plates 1, and a first sliding groove 16 is provided on both mounting plates 1;

[0082] Each of the four first slide grooves 16 is slidably connected to a first slider 17; the second rotating rod 12 and the third rotating rod 13 both extend into the adjacent first slide grooves 16 and are rotatably connected to the first slider 17.

[0083] The first groove 16, located at the position of the second rotating rod 12, extends to the top end face of the mounting plate 1;

[0084] In this embodiment, extension plates 18 are fixedly connected to the top of both mounting plates 1 by bolts;

[0085] The extension plate 18 is provided with a second sliding groove 19, and the second sliding groove 19 is connected to the first sliding groove 16 extending to the top end face of the mounting plate 1;

[0086] In this embodiment, the first rotating rod 11, the second rotating rod 12, and the third rotating rod 13 each include two threaded cylinders 131 and a threaded rod 132; the threaded rod 132 is located between the two threaded cylinders 131 and is threadedly engaged with the two threaded cylinders 131; a locking nut 133 is threadedly engaged on the threaded rod 132, and the locking nut 133 is used to lock the connection between the threaded rod 132 and the threaded cylinders 131; the rotating wheel 14 is fixed on the two threaded cylinders 131.

[0087] Two threaded cylinders 131 on the first rotating rod 11 rotate on two mounting plates 1; two threaded cylinders 131 on the second rotating rod 12 and the third rotating rod 13 rotate on adjacent first sliders 17; a hexagonal block 134 is fixedly connected to the middle of the threaded rod 132.

[0088] Each driven plate 2 includes a left plate 21 and a right plate 22; the left plate 21 is fixedly connected to one of the conveyor belts 15; the right plate 22 is fixedly connected to the other conveyor belt 15.

[0089] The left plate 21 is a rectangular plate, and a cross groove 23 is provided in the left plate 21; the right plate 22 is a cross plate, and the right plate 22 partially slides in the cross groove 23 provided in the left plate 21; the top and bottom of the right plate 22 both extend out of the cross groove 23.

[0090] The filter screen 3 includes a first mesh layer 31 and a second mesh layer 32; the first mesh layer 31 is fixedly connected between each of the two adjacent left plates 21; the second mesh layer 32 is fixedly connected between each of the two connected right plates 22, and the first mesh layer 31 and the second mesh layer 32 are staggered.

[0091] A first push plate 24 is fixedly connected to the end face of the left plate 21 away from the first mesh layer 31; a second push plate 25 is fixedly connected to the end face of the right plate 22 away from the first mesh layer 31, and the first push plate 24 and the second push plate 25 are staggered and fit together.

[0092] Specifically, when it is necessary to install a barrier structure in a drainage ditch of different widths, since the first rotating rod 11, the second rotating rod 12, and the third rotating rod 13 each include two threaded cylinders 131 and one threaded rod 132, the barrier structure is first placed into the drainage ditch. Then, the hexagonal blocks 134 on the three threaded rods 132 are rotated in a forward direction in sequence. The hexagonal blocks 134 will drive the threaded rods 132 to rotate. During the rotation of the threaded rods 132, the threaded rods 132 will gradually rotate out of the two threaded cylinders 131. At this time, the two threaded cylinders 131 move away from each other, so the overall length of the three rotating rods becomes longer. The rotating rod will push the two mounting plates 1 away from each other. During the process of the two mounting plates 1 moving away from each other, the mounting plates 1 will gradually come into contact with the side wall of the drainage ditch. When the two mounting plates 1 are against the side walls on both sides of the drainage ditch, the rotation of the hexagonal block 134 will stop. Then the locking nut 133 will be rotated. During the rotation, the locking nut 133 will move towards the threaded cylinder 131. When the locking nut 133 is against the threaded cylinder 131, the locking nut 133 can lock the connection between the threaded rod 132 and the threaded cylinder 131, thereby preventing the threaded rod 132 from rotating on its own.

[0093] More specifically, as the two threaded cylinders 131 move away from each other, the rotating wheels 14 on the rotating rod will move away from each other. As the rotating wheels 14 move away from each other, the two rotating belts 15 will move away from each other. As the two rotating belts 15 move away from each other, the left plate 21 and the right plate 22 will move away from each other. At this time, the right plate 22 will slide in the cross groove 23 of the left plate 21 and gradually slide out of the cross groove 23. At the same time, the left plate 21 will move the first mesh layer 31 and the right plate 22 will move the second mesh layer 32, so that the first mesh layer 31 and the second mesh layer 32 move away from each other. At the same time, the left plate 21 and the right plate 22 will move the first push plate 24 and the second push plate 25 away from each other. When the two mounting plates 1 are attached to the side walls on both sides of the drainage ditch, the overall conveyor mesh structure will become wider to adapt to the width of the drainage ditch, so that the barrier structure can be used for drainage ditches of different widths.

[0094] Furthermore, when it is necessary to install a barrier mechanism in drainage ditches at different heights, firstly, the threaded rods 132 on the second rotating rod 12 and the third rotating rod 13 are rotated in the opposite direction. The reverse-rotated threaded rods 132 will gradually rotate into the two threaded cylinders 131. At this time, the two threaded cylinders 131 will move closer to each other, and the moving threaded cylinders 131 will drive the first slider 17 to move. At this time, the first slider 17 is no longer pressed against the first sliding groove 16, and then pushes the second rotating rod 12 and the third rotating rod 13 to move upward. During the upward movement of the second rotating rod 12 and the third rotating rod 13, the position of the first rotating rod 11 remains unchanged. When the second rotating rod 12 moves upward, the first rotating rod 11 moves upward. After rod 12 and the third rotating rod 13 are moved to the appropriate position, the threaded rod 132 on the second rotating rod 12 and the third rotating rod 13 are rotated in the forward direction. The threaded rod 132 rotates in the forward direction and pushes the two threaded cylinders 131 away from each other. The threaded cylinders 131 push a slider 17 to slide into the first slide groove 16. When the first slider 17 is pressed into the first slide groove 16, the first slider 17 is fixed in the first slide groove 16. At the same time, the second rotating rod 12 and the third rotating rod 13 are also fixed. At this time, the height of the conveyor network structure will increase, so that the barrier structure can be applied to drainage ditches of different widths.

[0095] Meanwhile, since an extension plate 18 is fixedly connected to the mounting plate 1, and since the overall height of the mounting plate 1 is limited, an extension plate 18 with a second slide groove 19 can be installed on the mounting plate 1, thereby further increasing the overall height of the transmission network structure.

[0096] Example 3: A guide plate 5 is fixedly connected to the left side of the first rotating rod 11 between the two mounting plates 1;

[0097] In this embodiment, the guide plate 5 includes a first guide plate 51 and a second guide plate 52; a third groove 53 is provided in the first guide plate 51, and the second guide plate 52 slides in the third groove 53;

[0098] The opposite end faces of the first guide plate 51 and the second guide plate 52 are rotatably connected to the bottom positions of the first guide plate 51 and the second guide plate 52, and the first pins are rotatably mounted on the mounting plate 1.

[0099] The first guide plate 51 and the second guide plate 52 are rotatably connected to the opposite end faces of the first guide plate 51 and the second guide plate 52 at the top positions of the first guide plate 51 and the second guide plate 52.

[0100] Both mounting plates 1 have arc-shaped grooves 55 on the side near the second pin 54, and the second pin 54 slides in the arc-shaped grooves 55.

[0101] Specifically, since a guide plate 5 is provided at the position of the first rotating rod 11, when the water flow and the carried debris flow through the position of the guide plate 5, the water flow and debris will flow along the guide plate 5, thereby guiding the water flow and debris, so that the water flow and debris can move along the conveyor network structure, thereby allowing the water flow and debris to better drive the conveyor network structure to rotate, while avoiding the debris directly hitting the first rotating rod 11, thus preventing the first rotating rod 11 from being damaged;

[0102] More specifically, since the guide plate 5 includes a first guide plate 51 and a second guide plate 52, when the two mounting plates 1 are close to each other or far apart, the second guide plate 52 will slide in the third groove 53, thereby changing the overall length of the guide plate 5 and making the guide plate 5 adapt to the distance between the two mounting plates 1.

[0103] Since the first guide plate 51 and the second guide plate 52 are rotatably mounted on the mounting plate 1 via the first pin, the guide plate 5 will rotate around the first pin. When the height of the conveyor network structure changes, the rotating guide plate 5 can always be in contact with the driven plate 2, thus avoiding the situation where the guide plate 5 is fixed and cannot maintain contact with the driven plate 2 on the conveyor network structure when the height of the conveyor network structure changes.

[0104] Furthermore, since the second pin 54, which is fixedly connected to the first guide plate 51 and the second guide plate 52, rotates within the arc-shaped groove 55, the rotation angle of the guide plate 5 can be limited.

[0105] Example 4: A first motor 401 is installed on the storage box 48, and the first motor 401 is connected to the first rotating shaft 42;

[0106] A second motor is fixedly connected to the inner wall of one of the mounting plates 1, and the second motor is connected to the first rotating shaft 42;

[0107] A photovoltaic power generation system and a controller can be installed on the storage box 48. The photovoltaic power generation system is used to provide power to the first motor 401 and the second motor, and the controller is used to control the start and stop of the first motor 401 and the second motor.

[0108] Specifically, due to the existence of the photovoltaic power generation system, it can provide power to the first motor 401 and the second motor. By setting a controller, the controller can control the start and stop of the first motor 401 and the second motor. If the water flow and debris in the drainage ditch cannot drive the transmission network structure to rotate, the second motor can be controlled to rotate. The second motor will drive the first rotating rod 11 to rotate, thereby driving the entire transmission network structure to rotate. During the rotation of the transmission network structure, the debris in the water flow can be carried out, thereby preventing the debris from clogging the drainage ditch.

[0109] More specifically, if the water flow in the drainage ditch cannot drive the turbine 46 to rotate, the first motor 401 is controlled to rotate, which will drive the first shaft 42 to rotate. The first shaft 42 can drive the spiral blade 47 to rotate, thereby pushing the debris that falls into the collection box 4 into the storage box 48.

[0110] Example 5: A method for using a drainage ditch retaining structure for hydraulic design. The method uses the aforementioned drainage ditch retaining structure for hydraulic design, and the method of use is as follows:

[0111] Step 1: First, install the barrier structure inside the drainage ditch. When the drainage ditch is draining normally, the water will carry debris through the ditch and pass through the barrier structure.

[0112] Step 2: When the water and debris pass through the barrier structure, the water will pass through the conveyor network structure, and the rotating conveyor network structure will sift the debris out of the water.

[0113] Step 3: The screened debris will be transferred to the collection box 4, and then to the storage box 48, where it can be cleaned manually at regular intervals.
