Description

Technical Field

[0001] This invention relates to the field of river control technology, specifically to a flood discharge and flow control embankment. Background Technology

[0002] Flood control and discharge at dams refers to regulating water levels and flow by opening flood discharge facilities on dams, thereby reducing the pressure on the dams, protecting their safety, and controlling flood flow to minimize the impact on downstream areas. Flood discharge and flow control at dams are mainly achieved through sluice gates. However, after long-term use, sluice gates often exhibit the following defects: As river sand accumulates, the sediment on the bottom of the gate on the water-facing side will accumulate higher and higher, resulting in greater pressure on the gate and a higher water level at the gate. The current solution is to lower a sediment pump to remove the sediment. However, the working surface of the sediment pump cannot be accurately determined, and the amount of sediment removed cannot be accurately controlled. It is easy for too much sediment to be removed in some places and too little sediment to be removed in others, resulting in insufficient uniformity. During maintenance, it is necessary to regularly check the sealing of the gate, whether there are cracks or corrosion. Currently, the maintenance is mainly carried out by manual diving, which is labor-intensive and inefficient. Summary of the Invention

The first translation block is horizontally slidably embedded in the side of the first positioning plate, and the second translation block is slidably embedded in the side of the second positioning plate. The first drive rod is located on the inner wall of the first positioning plate and is connected to the first translation block. The first moving seat is a movable telescopic structure. In the sand cleaning state, the first drive rod is retracted and the first moving seat is extended, so that the third screw is disengaged from the first rotating rod to ensure that the separating assembly remains stationary. In the maintenance state, the first drive rod is extended and the first moving seat is retracted, so that the third screw is engaged with the first rotating rod.

In the maintenance state, the agitating blades are retracted to the upper dam body.

[0014] This invention provides a flood discharge and flow control dike. Compared with the prior art, it has the following advantages: The sand-shoveling component has the following effects: 1.1 When too much river sand accumulates at the bottom of the gate assembly, it can automatically extend to divide the accumulated sand layer, separating the redundant sand layer from the base sand layer.

Obviously, the described embodiments are only some embodiments of the present invention, 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. Example

[0019] To address the technical problems in the background section, the following flood discharge and flow control dam is proposed: Combination Figures 1-8As shown, the present invention provides a flood discharge and flow control dam, including a gate assembly 2. The gate assembly 2 has an upper dam body 11 at the top and a lower dam body 12 at the bottom. A first side dam body 13 is provided on one side of the gate assembly 2 and a second side dam body 14 is provided on the other side. A first storage tank 131 is provided inside the first side dam body 13, and the first storage tank 131 is located on the water-facing side of the gate assembly 2. A second storage tank 141 is provided at the bottom of the second side dam body 14. The inner sides of the first storage tank 131 and the second storage tank 141 are both open structures. A sealing groove 121 is provided in the middle of the top of the lower dam body 12. The bottom end of the gate assembly 2 extends into the sealing groove 121. A stop is provided on the surface of the lower dam body 12. The stop is located on the water-facing side of the gate assembly 2. The bottom end of the gate assembly 2 cooperates with the stop to stop. The first storage tank 131 is equipped with a partition component 6, a sand-shoveling component 7 and a first drive component 5. The sand-shoveling component 7 is located at the bottom of the partition component 6. The sand-shoveling component 7 is installed at the bottom of the second storage tank 141. The sand-shoveling component 4 is located above the sand-shoveling component 7. The bottom water-facing side of the gate component 2 is a sand accumulation layer. The upper layer of the sand accumulation layer is a redundant sand layer. The sand-shoveling component 4 is arranged opposite to the redundant sand layer. The flood discharge device includes the following states: In the closed state, the gate assembly 2 is closed, the separator assembly 6 and the sand-shoveling assembly 7 are received into the first storage tank 131, and the sand-suction assembly 4 is closed and received into the second storage tank 141. During flood discharge, gate assembly 2 rises to carry out flood discharge operations; In the sand-cleaning state, the sand-shoveling component 7 extends out separately, allowing it to be inserted into the sand accumulation layer. The top of the sand-shoveling component 7 is redundant sand accumulation. The sand-suction component 4 is activated to suck out the redundant sand accumulation with negative pressure. In the maintenance state, the flood discharge device first performs sand removal operation. After the redundant accumulated sand is cleaned up, the sand shovel assembly 7 and the partition assembly 6 extend outward simultaneously. The space between the partition assembly 6 and the gate assembly 2 is an open maintenance area, where maintenance personnel can carry out maintenance on the gate assembly 2.

[0020] In the above scheme, The sand-shoveling component 7 has the following effects: 1.1 When too much river sand accumulates at the bottom of the gate component 2, it can automatically extend to divide the accumulated sand layer, separating the redundant sand layer from the base sand layer. This makes it easier for the sand suction component 4 to work without adsorbing the relatively solidified mud and sand settled at the bottom. It only needs to act on the upper redundant sand layer, making the sand suction operation simpler, with higher adsorption accuracy and targeting, and without causing excessive power consumption of the adsorption component; 1.2 During maintenance, the sand-shoveling component 7 can seal the maintenance area from the bottom, keeping the maintenance area closed and preventing external water from entering the maintenance area from the bottom.

[0021] The sand suction component 4 has the following effects: it can actively absorb the sediment at the bottom of the main gate 21 under negative pressure, thereby avoiding excessive accumulation of mud and sand and raising the riverbed. It effectively solves the problem of mud and sand accumulation in front of the gate. At the same time, the sediment can be directly extracted under negative pressure, making cleaning simple and efficient. The partition component 6 has the following effects: when not in use, it can be stored in the first storage tank 131; when maintenance is required, the partition component 6 can extend to separate the maintenance area, allowing workers to conveniently and quickly perform maintenance on the outer surface of the main gate plate 21 without the need for traditional manual underwater maintenance, and allowing for regular maintenance with corrosion-resistant paint spraying.

[0022] In this embodiment, the gate assembly 2 includes a main gate 21, with multiple drainage holes opened inside the upper part of the main gate 21. A secondary gate 22 is rotatably installed inside each drainage hole. Hydraulic rods 23 are symmetrically installed on the back side of the secondary gate 22. The bottom end of the hydraulic rod 23 is hinged to the back side of the secondary gate 22, and the top end of the hydraulic rod 23 is hinged to the back side of the gate. Each hydraulic rod 23 is connected in parallel to a conveying oil pipe 24, and each conveying oil pipe 24 is connected to an oil pump 25. A gate lifting assembly is installed on the top surface of the upper dam body 11. A lower sealing plate is installed inside the sealing groove 121. Multiple sets of spring rods 123 are installed at the bottom of the lower sealing plate. In the closed state, the bottom end of the main gate plate 21 is inserted into the sealing groove 121. In the flood discharge state, the main gate plate 21 is lifted, and the spring rods 123 push the lower sealing plate to lift up, so as to seal the sealing groove 121.

[0023] In the above scheme, When the river water level is too high, the hydraulic rod 23 works to open the auxiliary gate 22, so that the drain hole is opened and the river water is discharged through the drain hole, thus realizing the primary level output. The design of the sealing groove 121 enables the main gate plate 21 to be sealed and stopped, resulting in a better sealing effect of the main gate plate 21. When flood discharge occurs, the spring rod 123 can push the sealing plate 122 upward, thereby blocking the sealing groove 121 and preventing sediment from clogging the sealing groove 121.

[0024] In this embodiment, the first drive assembly 5 includes a first motor 53, a first rotating rod, a first positioning plate 51, and a second positioning plate 52. The first positioning plate 51 and the second positioning plate 52 are positioned opposite each other in the second storage tank 141. The first positioning plate 51 and the second positioning plate 52 are located inside the separator assembly 6. A plurality of third screws 56 are horizontally installed above the first positioning plate 51 and the second positioning plate 52. A second screw 55 is horizontally installed below the first positioning plate 51 and the second positioning plate 52. The output end of the first motor 53 is connected to a first screw 54. The first screw 54 is vertically arranged and located in the second storage tank 141 on the side away from the gate assembly 2. The first screw 54 and the second screw 55 are vertically meshed and connected. The first screw 54 and the third screw 56 are movably meshed and connected. The sand-shoveling assembly 7 is threadedly fitted onto the second screw 55, and the separator assembly 6 is threadedly fitted onto the third screw 56.

[0025] In the above scheme, During sand removal, the separator 6 disengages from the third screw 56, and the first motor 53 drives the third screw 56 to rotate. The third screw 56 then drives the sand-shoveling assembly 7 to extend, thus achieving automatic sand removal.

[0026] During maintenance, the separator assembly 6 engages with the third screw 56, the first motor 53 drives the third screw 56 to rotate, and the third screw 56 drives the sand-shoveling assembly 7 and the separator assembly 6 to extend synchronously.

[0027] In this embodiment, the sand-shoveling assembly 7 includes a shovel plate 71, which is horizontally arranged. A first movable seat 72 is provided at the outer end of the surface of the shovel plate 71, and the first movable seat 72 is threadedly fitted onto the second screw 55. In the closed state, the shovel plate 71 is retracted into the first storage tank 131, and in the sand-cleaning state, the shovel plate 71 extends out of the first storage tank 131.

[0028] In this embodiment, the separating component 6 includes a side sealing plate 61 and a main sealing plate. The main sealing plate and the main gate plate 21 are arranged parallel to each other. The side sealing plate 61 is vertically provided at the outer end of the inner side of the main sealing plate. The inner wall of the main sealing plate is provided with a plurality of second movable seats 62. The second movable seats 62 are threadedly fitted onto the third screw 56. In the closed state, the main sealing plate is retracted into the first storage tank 131, the side sealing plate 61 blocks the inner opening of the first storage tank 131, and the shovel plate 71 is placed below the main sealing plate. In the sand-cleaning state, the side sealing plate 61 and the main sealing plate extend out of the first storage tank 131, and the side sealing plate 61, the main sealing plate and the main gate plate 21 form a maintenance area.

[0029] In the above scheme, Setting up a side sealing plate 61 can form a side seal for the maintenance area and a seal for the opening when the main sealing plate is inserted into the first storage tank 131.

[0030] In this embodiment, one end of the third screw 56 is rotatably embedded in the first translation block 561, and the other end is rotatably embedded in the second translation block 562. The first translation block 561 is horizontally slidably embedded in the side of the first positioning plate 51, and the second translation block 562 is slidably embedded in the side of the second positioning plate 52. The first drive rod 57 is disposed on the inner wall of the first positioning plate 51 and is connected to the first translation block 561. The first moving seat 72 is a movable telescopic structure. In the sand cleaning state, the first drive rod 57 is retracted and the first moving seat 72 is extended, so that the third screw 56 is disengaged from the first rotating rod to ensure that the separating component 6 remains stationary. In the maintenance state, the first drive rod 57 is extended and the first moving seat 72 is retracted, so that the third screw 56 is engaged with the first rotating rod.

[0031] In this embodiment, the bottom end of the side sealing plate 61 is provided with a second drive rod 63, the bottom end of the second drive rod 63 is provided with a locking pin 64, and the outer end of the surface of the sand scraper is provided with a locking hole 711; in the maintenance state, the second drive rod 63 extends, so that the locking pin 64 is inserted into the locking hole 711, so that the main sealing plate and the sand scraper extend synchronously, and the sand scraper 71 blocks the maintenance area from below.

[0032] In the above scheme, the locking pin 64 and the locking hole 711 are designed to work together to ensure that the main sealing plate and the sand-shoveling plate can be moved out synchronously and stably during maintenance. The two can be connected as one unit, which has higher movement stability and stronger water pressure resistance.

[0033] In this embodiment, the sand suction assembly 4 includes an outer casing 41 and a side baffle 42. The bottom of the inner wall of the second side dam 14 is provided with vertically distributed receiving grooves. The side baffle 42 is slidably embedded inside the receiving grooves. The receiving grooves are located at the inner end of the second storage tank 141. The outer casing 41 is fixed to the inner outer end of the second storage tank 141. The inner side of the outer casing 41 is an open structure. The inner end of the outer casing 41 is connected to the sand suction pump 44. A first traction assembly 43 is installed on the top of the upper dam 11. The first traction assembly 43 is connected to the side baffle 42. An agitator is installed inside the outer casing 41. In the closed state, the side baffle 42 blocks the outer casing 41. In the sand cleaning state, the side baffle 42 is lifted, and the sand suction pump 44 and the agitator operate.

[0034] In the above scheme, the first traction component 43 includes a first traction motor and a first traction rope; The side baffle 42 can externally enclose the outer casing 41, preventing water and sand from entering the outer casing 41 when not cleaned, thus effectively protecting the outer casing 41. The design of the stirring rod can agitate the sucked mortar, thereby improving the mortar mixing effect, preventing mortar from clogging the outer casing 41, and accelerating the negative pressure suction effect.

[0035] In this embodiment, the outlet of the sand pump 44 is connected to the sand discharge pipe 45, and the outlet end of the sand discharge pipe 45 is connected to the vibration separation box 3. The vibration separation box 3 is located on the top of the second side dam 14. The bottom of the vibration separation box 3 is provided with the sand discharge pipe 45 and the drainage pipe. The outlet of the drainage pipe extends to the water-facing side of the second side dam 14 through the drainage pipe.

[0036] In the above scheme, The slurry pumped out by the sand pump 44 can be separated by the vibrating separation box 3, thus enabling the direct output of river sand and automatic recycling of river sand, avoiding the waste of redundant river sand; the separated river water can be directly discharged into the river, realizing the complete treatment of recycled river sand.

[0037] Although a stirring rod is installed in the outer casing 41, it is still difficult for the accumulated redundant sand layer to flow into the outer casing 41. To solve this problem, the following solution is proposed: In this embodiment, a second traction assembly 82 is provided on the top of the upper dam body 11, and vertical guide rails 81 are symmetrically provided on the water-facing side of the main gate 21. Each vertical guide rail 81 is equipped with a set of agitating assemblies 8. The agitating assembly 8 includes a second motor 83, and the output end of the second motor 83 is connected to agitating blades 84. In the sand-cleaning state, the agitating blades 84 extend into the redundant sand layer and agitate the redundant sand, so that the redundant sand and water are mixed to form mortar, so that the mortar can enter the outer box 41 under negative pressure. In the maintenance state, the agitating blades 84 are retracted into the upper dam body 11.

[0038] In the above scheme, the second traction component 82 includes a second traction motor and a traction rope; During sand cleaning, the second traction component 82 lowers the agitator component 8, causing the agitator blade 84 to sink into the redundant sand layer. The second motor 83 drives the agitator blade 84 to rotate, thereby mixing the river sand and water to produce mortar, which can then flow quickly into the outer casing 41.

[0039] Working principle and usage process of this invention: In the closed state, the gate assembly 2 is closed, the separator assembly 6 and the sand-shoveling assembly 7 are stored in the first storage tank 131, and the sand-suction assembly 4 is closed and stored in the second storage tank 141. When the river water level is too high, the hydraulic rod 23 works to open the auxiliary gate 22, so that the drain hole is opened and the river water is discharged through the drain hole, realizing the primary level output. The design of the sealing groove 121 can realize the sealing and stopping of the main gate 21, and the sealing effect of the main gate 21 is better. In the flood discharge state, the gate assembly 2 rises to carry out flood discharge operations; when discharging floodwater, the spring rod 123 can push the sealing plate 122 up to block the sealing groove 121 and prevent sediment from clogging the sealing groove 121.

[0040] In the sand-cleaning state, the sand-shoveling component 7 extends out separately, allowing it to be inserted into the sand accumulation layer. The top of the sand-shoveling component 7 is redundant sand accumulation. The sand-suction component 4 is activated to suck out the redundant sand accumulation with negative pressure. The first drive rod 57 retracts, and the first movable seat 72 extends, causing the third screw 56 to disengage from the first rotating rod, so as to ensure that the separating component 6 remains stationary. The first motor 53 drives the third screw 56 to rotate, and the third screw 56 can drive the sand-shoveling component 7 to extend, thereby realizing automatic sand shoveling.

[0041] In the maintenance state, the flood discharge device first performs sand removal operation. After the redundant accumulated sand is cleaned up, the sand shovel assembly 7 and the partition assembly 6 extend outward simultaneously. The space between the partition assembly 6 and the gate assembly 2 is an open maintenance area, where maintenance personnel can carry out maintenance on the gate assembly 2.

[0042] The first drive rod 57 extends, the first movable seat 72 retracts, so that the third screw 56 engages with the first rotating rod, the second drive rod 63 extends, so that the locking pin 64 is inserted into the locking hole 711, so that the main sealing plate and the sand-shoveling plate extend synchronously, and the sand-shoveling plate 71 blocks the maintenance area from below; the first motor 53 drives the third screw 56 to rotate, and the third screw 56 drives the sand-shoveling assembly 7 and the separating assembly 6 to extend synchronously; The second traction component 82 lowers the stirring component 8, causing the stirring blades 84 to sink into the redundant sand layer. The second motor 83 drives the stirring blades 84 to rotate, thereby mixing the river sand and water to produce slurry, which can then flow quickly into the outer casing 41. The side baffle 42 is lifted, and the sand pump 44 and stirring rod are activated. The slurry pumped out by the sand pump 44 can be separated by the vibrating separation box 3, thus enabling the direct output of river sand and automatic recycling of river sand, avoiding the waste of redundant river sand. The separated river water can be directly discharged into the river, achieving complete processing of the recycled river sand.
