Description

Technical Field

[0001] This utility model relates to the field of water conservancy equipment, and in particular to a gate and pumping station water-stopping structure. Background Technology

[0002] Hydraulic gates are hydraulic structures built on rivers to control the flow of water within them. Closing the gates can prevent floods, tides, or raise upstream water levels to meet the needs of irrigation, power generation, navigation, aquaculture, environmental protection, industrial and domestic water use; opening the gates can release floodwaters, waterlogged water, wastewater, or polluted water, and can also supply water to downstream rivers or canals.

[0003] The gate water-stopping system is a seepage prevention device used to seal gaps in gates. It usually consists of a gate and a sealing device attached to the gate, which can prevent river water from seeping or spraying, effectively improving the water-blocking function of the gate.

[0004] However, upstream water flow may carry floating debris downstream, which can affect the water quality. Also, if floating debris gets caught in the sluice gate, it can easily cause the gate to not close properly, creating a leakage channel and affecting the water-stopping effect. Utility Model Content

[0005] The purpose of this invention is to provide a gate water-stopping structure that can effectively prevent floating objects from being drawn into the gate outlet and causing the gate to not close properly, and to reduce the amount of floating objects entering the downstream area.

[0006] To solve the above-mentioned technical problems, this utility model provides a gate water-stopping structure, including gate piers placed on both sides and a gate that is raised and lowered between the gate piers. The gate has a collection component on the water-facing side. The collection component includes at least two collection cylinders arranged opposite each other for intercepting floating objects. The collection cylinders have openings and drainage holes on both sides, so that when the collection cylinders float on the water surface, the openings face the water-facing side and the drainage holes face the back water side.

[0007] Furthermore, adjacent collection cylinders are rotatably connected by a rotating shaft. One side of the rotating shaft is connected to the gate by a pull rope, and the pull rope is wound around a pulley at the gate pier so that when the gate rises, the collection cylinder is in the collecting state, and when the gate falls, the collection cylinder is pulled by the pull rope.

[0008] Furthermore, a discharge port is provided at the end of the collecting cylinder, and a baffle is rotatably provided at the discharge port so that when the collecting cylinder is pulled to an inclined state by the pull rope, the baffle opens to discharge the material.

[0009] Furthermore, a storage trough is connected to the side of the gate pier, and when the collecting cylinder discharges material, the discharge port corresponds to the storage trough.

[0010] Furthermore, the discharge port side has a first adsorption element, and the baffle side has a second adsorption element that adsorbs and cooperates with the first adsorption element.

[0011] Furthermore, the opening has a limiting plate on the side near the discharge port, and the water-facing surface of the limiting plate has an inclined guide surface.

[0012] Furthermore, the collecting cylinder has a counterweight on one side, and when the opening faces the water-facing side, the counterweight is located on the lower side of the collecting cylinder.

[0013] Furthermore, a connecting pile is provided on the top of the gate pier, and a threaded rod is rotatably installed at the connecting pile, and the threaded rod is threadedly engaged with the gate.

[0014] Furthermore, one end of the collecting cylinder with the discharge port is connected to the storage tank via a limiting rope.

[0015] The beneficial effects of this utility model are as follows: by limiting the two sides of the gate by the gate pier, the gate can be stably raised and lowered along the gate pier, thereby controlling the drainage and water stop states. When the gate is raised to open for drainage, the collection cylinder is in a collecting state under the action of buoyancy, so that the opening faces the water-facing side to effectively intercept floating objects and guide the intercepted floating objects into the collection cylinder. At the same time, the drainage hole maintains stable drainage, avoiding the situation where the water entering the collection cylinder cannot be discharged and floating objects overflow. Thus, in the drainage state, the floating objects are effectively collected in the collection cylinder, avoiding the situation where a large number of floating objects are rolled into the gate closure or discharged downstream.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0024] like Figures 1-4 The present invention provides a gate station water-stopping structure, including gate piers 1 placed on both sides and a gate 2 raised and lowered between the gate piers 1. The gate 2 has a collection component on the water-facing side. The collection component includes at least two collection cylinders 3 arranged opposite each other for intercepting floating objects. The collection cylinders 3 have openings 4 and drainage holes 5 on both sides, so that when the collection cylinders 3 float on the water surface, the openings 4 face the water-facing side and the drainage holes 5 face the back water side.

[0025] By limiting the gate on both sides through the gate piers, the gate can be stably raised and lowered along the gate piers, thereby controlling the drainage and water stop states. When the gate is raised to open for drainage, the collection cylinder is in a collecting state under the action of buoyancy, so that the opening faces the water-facing side to effectively intercept floating objects and guide the intercepted floating objects into the collection cylinder. At the same time, the drainage hole maintains stable drainage, avoiding the situation where the water entering the collection cylinder cannot be discharged and floating objects overflow. Thus, in the drainage state, the floating objects are effectively collected in the collection cylinder, preventing a large number of floating objects from being rolled into the gate closure or discharged downstream.

[0026] Specifically, the gate piers are connected to both sides of the gate opening of the gate station to stabilize the gate on the side, and there are guide rails between the gate piers and the gate to ensure the stable raising and lowering of the gate.

[0027] In one embodiment of this solution, a connecting pile 17 is provided on the top of the gate pier 1, and a screw rod 18 is rotatably provided at the connecting pile 17. The screw rod 18 is threadedly engaged with the gate 2. The rotation of the screw rod is controlled by a motor installed in the connecting pile, thereby driving the gate to rise and fall through the threaded engagement.

[0028] Preferably, two adjacent collection cylinders 3 are rotatably connected by a rotating shaft 6. One side of the rotating shaft 6 is connected to the gate 2 by a pull rope 7, and the pull rope 7 is wound around a pulley 8 passing through the gate pier 1, so that when the gate 2 rises, the collection cylinder 3 is in the collecting state, and when the gate 2 falls, the collection cylinder 3 is pulled by the pull rope 7.

[0029] Specifically, the pull rope bypasses the pulley, so that the raising and lowering of the gate and the pulling and releasing of the pull rope on the rotating shaft are in opposite directions. That is, when the gate rises, the pull rope is relaxed and the collection cylinder is in a collecting state; when the gate falls, the pull rope is tightened, and the collection cylinder is pulled up and tilted through the rotating shaft. The advantage of this is that when the gate is open to drain water, the collection cylinder can effectively intercept and collect floating objects guided by the water flow, preventing them from entering the gate with the water flow and causing blockage or damage. When the gate is closed to stop the water flow, the collection cylinder tilts and rises accordingly, and the floating objects remaining inside are discharged along the tilted collection cylinder to the designated recycling location.

[0030] Since the two adjacent collection cylinders are connected by a rotating shaft, when the shaft is pulled by the rope, the collection cylinders on both sides tilt to the sides, forming a symmetrical flipping discharge action, which makes it easy to concentrate and dump the floating objects collected inside to both sides.

[0031] In one embodiment of this solution, the pulley is located at the connecting pile to ensure that the pull rope can be connected to the middle position of the gate.

[0032] Preferably, the end of the collecting cylinder 3 is provided with a discharge port 9, and a baffle 10 is rotatably provided at the discharge port 9 so that when the collecting cylinder 2 is pulled to an inclined state by the pull rope 7, the baffle 10 opens to discharge material.

[0033] Specifically, when the collection cylinder is lifted to the inclined discharge position, the baffle is opened by the push of the floating objects, causing the floating objects inside the collection cylinder to slide down the inclined inner wall of the collection cylinder to the discharge port and be discharged to the preset recycling area. When the collection cylinder is in the collection state, the baffle can block the floating objects entering the collection cylinder to prevent the floating objects from being discharged from the discharge port again.

[0034] In one embodiment of this solution, the discharge port 9 has a first adsorption element 12 on its side, and the baffle 10 has a second adsorption element 13 on its side that is adsorbed to the first adsorption element 11. When the collection cylinder is tilted to discharge material, when the weight of the floating object exceeds the adsorption force between the first and second adsorption elements, the baffle is pushed open and the material is discharged. When the collection cylinder is in the collection state, since the collection cylinder is floating horizontally, the pushing force of the floating object on the baffle is small, thereby ensuring the limiting effect of the baffle on the floating object in the collection cylinder.

[0035] The first and second adsorption components can be magnetically attracted to each other.

[0036] Preferably, a storage trough 11 is connected to the side of the gate pier 1, and when the collecting cylinder 3 discharges material, the discharge port 9 corresponds to the storage trough 11.

[0037] Specifically, when the collection cylinder is tilted to discharge material, the discharge port is directly opposite the opening of the storage tank, which makes it easy for floating objects to slide into the tank and be stored in a concentrated manner, avoiding scattering and secondary pollution. Only the floating objects in the storage tank need to be cleaned periodically.

[0038] Preferably, the opening 4 has a limiting plate 14 on the side near the discharge port 9, and the water-facing surface of the limiting plate 14 has an inclined guiding surface 15.

[0039] Specifically, after the floating objects enter the collection cylinder, they are pushed by the floating objects behind them, causing the floating objects in front to move continuously into the collection cylinder and eventually move to the end near the discharge port. At this time, the limiting plate can block the floating objects and prevent them from overflowing from the opening under the impact of the water flow, thereby ensuring the stability of the collection process.

[0040] The design of the guide surface allows the floating objects to be guided by the inclined guide surface when the water flow carries them to the opening, so that they can smoothly enter the collection tube. At the same time, it reduces the reverse resistance caused by the obstruction of the water flow, which hinders the entry of the floating objects.

[0041] Preferably, the collecting cylinder 3 has a counterweight 16 on one side, and when the opening 4 faces the water-facing side, the counterweight 16 is located on the lower side of the collecting cylinder 3.

[0042] Specifically, when the collection cylinder is in the collection state, the counterweight can improve the orientation of the collection cylinder on the water surface, ensuring that the opening faces the water-facing side, thereby ensuring the stable collection of floating objects.

[0043] It is worth mentioning that the collection tube itself can be made of lightweight materials such as plastic, which gives the collection tube a certain buoyancy. The setting of the counterweight shifts the center of gravity downward, ensuring that the opening of the collection tube is located at the water level, avoiding the situation where the water level is higher or lower than the opening, making it difficult for floating objects to enter the collection tube.

[0044] Preferably, one end of the collecting cylinder 3 with the discharge port 9 is connected to the storage tank 11 via a limiting rope 19.

[0045] Specifically, the two ends of the collecting cylinder are respectively limited by pull rope and limit rope, so that the collecting cylinder can be stably positioned in the horizontal collecting state or the inclined discharging state, avoiding drifting with the water flow and affecting the collecting or discharging direction.

[0046] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
