Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a novel integrated pump gate. Background Technology

[0002] An integrated pump-gate system is a water conservancy engineering facility that integrates a water pump and a gate into one unit. It has both water-blocking and drainage functions and is widely used in river regulation, flood control and drainage, and water circulation. The water pump is installed on the gate, which is both a water-blocking structure and a support structure for the water pump. It can not only achieve unidirectional drainage, but also bidirectional water flow control (the gate can be opened to pump water from the inside to the outside, or the water pump can rotate in the opposite direction to replenish water from the outside to the inside). Compared with traditional pumping stations, it has advantages such as saving space, facilitating construction and maintenance, and high efficiency and energy saving.

[0003] Currently, in the practical application of integrated pump gates, to prevent the water pump from being blocked by garbage, debris, bricks, and other particles in the water, existing published patent documents CN116791529B (an integrated pump gate with automatic cleaning and anti-clogging function) and CN218667418U (an integrated pump gate's sludge removal mechanism) both employ a dual interception and filtration measure. This involves first designing a debris-blocking device, and then adding a sedimentation well between the debris-blocking device and the pump gate. A sludge pump is then placed in the sedimentation well to remove the settled garbage, particles, or sludge. However, in actual working scenarios, sedimentation wells are typically trenches designed along the width of the river channel. These horizontally designed trenches at the bottom of the river serve to settle garbage, particles, or sludge in the water. However, simply using a sludge pump for sludge removal is insufficient due to the length of the sedimentation well and the limited pumping power, resulting in poor cleaning performance.

[0040] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0041] like Figure 1 As shown, this embodiment discloses a novel integrated pump gate, including a pump gate 1. Slow-settling troughs 2 are provided on both the front and rear sides of the pump gate 1. A filter grid mechanism 3 is installed within the slow-settling troughs 2. An interception mechanism 4 is provided on the side of the slow-settling trough 2 located on one side of the inner waterway 5, away from the pump gate 1. The filter grid mechanism 3 includes a bottom basket 3-1, the shape of which matches the shape of the slow-settling trough 2. A main filter grid 3-2 is fixedly connected to the middle position inside the bottom basket 3-1, and the top of the main filter grid 3-2 is connected to a lifting mechanism 3-3. It should be noted that in this embodiment, the slow-settling trough 2 is a trapezoidal trench structure, horizontally positioned at the bottom of the inner waterway 5, serving the same function as the sedimentation well in the prior art.

[0042] The inner waterway 5 includes a first interception zone 5-1, a second interception zone 5-2, and an arc-shaped waterway 5-3. The interception mechanism 4 is installed on the arc-shaped waterway 5-3 of the first interception zone 5-1 for the first interception and filtration. The filter screen mechanism 3 is installed in the second interception zone 5-2 for the second interception and filtration. The bottom of the second interception zone 5-2 is lower than the bottom of the first interception zone 5-1, and the second interception zone 5-2 is connected to the first interception zone 5-1 by a slope. Specifically, the upper edge of the arc-shaped waterway 5-3 near the pump gate 1 is connected to the upper edge of the slow sedimentation trough 2 near the interception mechanism 4 by a slope.

[0043] In this embodiment, after the interception mechanism 4 performs the first interception and filtration on the water in the first interception zone 5-1, the water flows into the second interception zone 5-2. Some of the garbage and particulate matter in the water that is not intercepted by the interception mechanism 4 will be deposited in the bottom basket 3-1 in the slow settling tank 2 due to their own gravity. The garbage and particulate matter in the water will also fall into the bottom basket 3-1 after hitting the main filter grid plate 3-2. When there is too much garbage, particulate matter and silt deposited, the bottom basket 3-1 can be lifted into the pump room for cleaning using the lifting mechanism 3-3.

[0044] like Figure 2 As shown, the lifting mechanism 3-3 includes a first frame 3-3-1, on which a first screw gate opener 3-3-4 is mounted. A first screw 3-3-2 is threadedly connected within the first screw gate opener 3-3-4, and the bottom end of the first screw 3-3-2 is fixedly connected to the top end of the main filter plate 3-2. A first sleeve 3-3-5 is also mounted on the first frame 3-3-1, and a first guide rod 3-3-3 is slidably connected within the first sleeve 3-3-5. The bottom end of the first guide rod 3-3-3 is fixedly connected to the top end of the main filter plate 3-2. The screw gate opener, being a commonly used existing technology, will not be described in detail here. When the first screw gate hoist 3-3-4 starts, the first screw 3-3-2 pulls the main filter screen 3-2 and the bottom basket 3-1 upward, causing them to leave the water surface and enter the pump room. The first guide rod 3-3-3 and the first sleeve 3-3-5 play a guiding role. At this time, the garbage, particles, silt and other sediments deposited in the bottom basket 3-1 can be cleaned.

[0045] like Figure 3As shown, the bottom basket 3-1 includes a bottom plate 3-1-1, front and rear side plates 3-1-2, and left and right side plates 3-1-3. The main filter grid plate 3-2 is located in the middle of the bottom plate 3-1-1. The front and rear side plates 3-1-2 are fixedly connected to the bottom plate 3-1-1. The bottom edges of the left and right side plates 3-1-3 are rotatably connected to the bottom plate 3-1-1 via hinges. The sides of the left and right side plates 3-1-3 are detachably connected to the front and rear side plates 3-1-2 via hinges and bolt assemblies. An upper filter side plate 3-1-4 is fixedly connected to the upper edge of the front and rear side plates 3-1-2. The height of the front and rear side plates 3-1-2 and the left and right side plates 3-1-3 is the same as the height of the settling tank 2. After the bottom basket 3-1 is pulled into the pump house, the bolts can be removed to open the left and right side plates 3-1-3, and then the garbage, particles, and sludge deposited in the bottom basket 3-1 can be cleaned out using tools. It should be noted that the bottom plate 3-1-1, front and rear side plates 3-1-2, and left and right side plates 3-1-3 are all made of stainless steel without mesh, while only the upper filter side plate 3-1-4 is a filter grid structure with mesh. When the bottom basket 3-1 is located in the settling tank 2, the position of the upper filter side plate 3-1-4 will be higher than the upper edge of the trough opening on the side of the settling tank 2 closest to the pump gate 1. It is important to note that sediment, particles, silt, etc., inside the bottom basket 3-1 should not accumulate above the upper edge of the settling tank 2 and must be cleaned beforehand. When the bottom basket 3-1 is pulled upwards, some of the water inside will flow out through the upper filter side plate 3-1-4.

[0046] like Figures 4 to 7 As shown, the interception mechanism 4 includes a rotating shaft 4-1, on which a rotating debris-blocking basket 4-2 is mounted. The rotating shaft 4-1 is connected to a drive mechanism 4-3. The filtration apertures of the main filter plate 3-2 and the upper filter side plate 3-1-4 are smaller than the filtration apertures of the rotating debris-blocking basket 4-2. In this embodiment, the drive mechanism 4-3 is a motor, which is mounted on the ground on one side of the waterway. The motor's output shaft is connected to the rotating shaft 4-1 and drives the rotating shaft 4-1 to rotate. The other end of the rotating shaft 4-1 is rotatably mounted on the ground on the other side of the waterway via a bearing. In this embodiment, three rotating debris-blocking baskets 4-2 are mounted on the rotating shaft 4-1, one of which is located in the water. The rotating debris-blocking basket 4-2 is close to the arc-shaped waterway 5-3 at the bottom of the first debris-blocking zone 5-1, intercepting and filtering garbage, impurities, particulate matter, silt, etc., in the water. When the rotating debris-blocking basket 4-2 in the water needs to be cleaned, the drive mechanism 4-3, i.e., the motor, is activated to rotate, causing the rotating debris-blocking basket 4-2 in the water to rotate above the water surface for cleaning, while one of the rotating debris-blocking baskets 4-2 that was originally located outside the water surface rotates into the water to continue its interception and filtration function.

[0047] In this embodiment, the rotating debris-blocking basket 4-2 includes a main debris-blocking filter plate 4-2-1. One long side of the main debris-blocking filter plate 4-2-1 is fixedly connected to the rotating shaft 4-1, and the other long side of the main debris-blocking filter plate 4-2-1 is fixedly connected to a bottom debris-blocking filter plate 4-2-2. Side debris-blocking filter plates 4-2-3 are provided on both sides of the main debris-blocking filter plate 4-2-1. A baffle 4-2-4 is provided on the side of the main debris-blocking filter plate 4-2-1 near the rotating shaft 4-1. The bottom debris-blocking filter plate 4-2-2 has an arc-shaped structure. The arc of the arc-shaped waterway 5-3 matches the arc of the bottom debris-blocking filter plate 4-2-2. The arc of the arc-shaped waterway 5-3 and the arc of the bottom debris-blocking filter plate 4-2-2 form a concentric circle with the rotating shaft 4-1 as the center, thereby ensuring that the rotating debris-blocking basket 4-2 can rotate smoothly into position. In this embodiment, the side filter plate 4-2-3 and the main filter plate 4-2-1 are rotatably connected by hinges, and the side filter plate 4-2-3 is detachably connected to the baffle 4-2-4 and the bottom filter plate 4-2-2 by bolt assemblies. Except for the baffle 4-2-4, which is a solid smooth plate without filter mesh, the rest are filter grid structures. When the rotating debris basket 4-2 is rotated above the water surface and needs to be cleaned, the side debris filter plate 4-2-3 can be opened, and tools can be used to clean out the garbage, particles, silt, etc. between the main debris filter plate 4-2-1 and the bottom debris filter plate 4-2-2. The function of the baffle plate 4-2-4 is to prevent the garbage, particles, silt, etc. between the main debris filter plate 4-2-1 and the bottom debris filter plate 4-2-2 from sliding down the main debris filter plate 4-2-1 onto the rotating shaft 4-1 during the rotation process. Even if some garbage, particles, silt slides down, it will be intercepted on the baffle plate 4-2-4.

[0048] like Figure 8As shown, in this embodiment, the pump gate 1 includes a second frame 1-1, on which a second screw hoist 1-2 is installed. A second screw 1-3 is installed inside the second screw hoist 1-2, and the bottom end of the second screw 1-3 is fixedly connected to the top of the gate plate 1-4. A second sleeve 1-5 is also installed on the second frame 1-1, and a second guide rod 1-6 is slidably connected inside the second sleeve 1-5. The bottom end of the second guide rod 1-6 is fixedly connected to the top of the gate plate 1-4. A gate pump 1-7 is installed on the gate plate 1-4. The second screw hoist 1-2 can drive the gate plate 1-4 to rise and fall. When the gate plate 1-4 is closed, starting the gate pump 1-7 to rotate can discharge water from the inner waterway 5 into the outer waterway 6, or the gate pump 1-7 can be rotated in the opposite direction to replenish water from the outer waterway 6 into the inner waterway 5. Those skilled in the art should know that the gate pump 1-7 includes an installation pipe, which is installed on the gate plate 1-4. A water pump is installed inside the installation pipe, and a flap gate is installed at one end of the installation pipe. One end of the flap gate is rotatably connected to the installation pipe, and the flap gate is rotatably connected to the telescopic end of a hydraulic rod. The fixed end of the hydraulic rod is rotatably connected to the gate plate 1-4. After opening the flap gate, starting the water pump allows for drainage. After closing the water pump and the flap gate, it functions like a regular gate, separating the water on both sides. The gate pump 1-7 is a commonly used prior art and will not be described in more detail here. In this embodiment, in order to also play a filtering and intercepting role when the gate pump 1-7 is replenished with water in reverse (that is, when the water from the outer water channel 6 is replenished into the inner water channel 5), a filter grid mechanism 3 is also installed on the side of the pump gate 1 facing the outer water channel 6.

[0049] The operation process of this utility model is as follows:

[0050] Firstly, during normal operation, when the inner waterway 5 is neither drained nor replenished, the water in the inner waterway 5 first passes through the first interception zone 5-1 and undergoes initial interception and filtration in the rotating interception basket 4-2. The filtered water then enters the second interception zone 5-2. Smaller amounts of silt and sand that are not intercepted by the rotating interception basket 4-2 will settle in the bottom basket 3-1 within the settling tank 2 due to their own gravity and the filtration effect of the main filter plate 3-2. This dual filtration and interception achieves maximum filtration of the water entering the pump, thus protecting the pump.

[0051] When the rotating debris-blocking basket 4-2 needs cleaning after prolonged use, activate the drive mechanism 4-3 to rotate the shaft 4-1, bringing the rotating debris-blocking basket 4-2 above the water surface. Remove the bolt assembly, open the side debris-blocking filter plate 4-2-3, and use tools to clean out the debris, particles, and silt between the main debris-blocking filter plate 4-2-1 and the bottom debris-blocking filter plate 4-2-2. The baffle plate 4-2-4 prevents debris, particles, and silt from sliding down the main debris-blocking filter plate 4-2-1 onto the shaft 4-1 during rotation.

[0052] When the bottom basket 3-1 has been used for a long time and the internal sediment does not exceed the upper edge of the settling tank 2, it can be cleaned. Start the first screw hoist 3-3-4 to pull the main filter screen 3-2 and the bottom basket 3-1 into the pump room, remove the bolt assembly to open the left and right side plates 3-1-3, and use tools to clean out the garbage, particles, and silt deposited in the bottom basket 3-1. This ensures that the settling tank 2 is clean and tidy.

[0053] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
