Description

Technical Field

[0001] This utility model relates to the field of sluice gates, and in particular to a corrosion-resistant sluice gate structure for water conservancy pumping stations. Background Technology

[0002] A low-head hydraulic structure built on rivers and canals to control flow and regulate water levels using gates. Closing the gates can block 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, waterlogging, sewage or wastewater, and can also supply water to downstream rivers or canals.

[0003] For some sluice gates on rivers, the main structure is made of concrete, and the gate plates are used to close the river channel and block the water flow. However, the existing sluice gate structures still have some shortcomings and areas for improvement in actual use. Most existing sluice gate structures are made of reinforced concrete, which usually requires on-site construction and takes a long time. Although concrete is strong and durable, prolonged contact with water will cause various components in the water to corrode the gate plates, thereby reducing the overall strength. At the same time, during the use of the sluice gate, some silt will accumulate at the front end of the gate plate due to the water flow. Most existing sluice gate structures cannot directly clean and operate this silt. Therefore, those skilled in the art provide a corrosion-resistant sluice gate structure for water conservancy pumping stations to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a corrosion-resistant sluice gate structure for water conservancy pumping stations. By setting multiple grooves on the front and rear side walls of the gate, the contact area with water is increased, and the pressure of water on the gate is dispersed. At the same time, a corrosion-resistant layer and a reinforcing layer are set to improve the corrosion resistance and overall strength of the gate, reducing the overall service life caused by environmental impact. Meanwhile, the internal concrete intermediate layer increases the overall weight, making it more stable during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant sluice gate structure for a water conservancy pumping station, comprising a base plate, a retaining frame disposed at the center of the upper end face of the base plate, diagonal braces fixedly connected to the front and rear side walls near the side edges of the retaining frame, the lower ends of the four diagonal braces fixedly connected to the upper end face of the base plate, a retrieval structure disposed at the center of the upper end face of the base plate near the front edge, sliding grooves disposed at the center of the two inner side walls of the retaining frame, and a gate structure disposed inside the retaining frame between the two sliding grooves. The two side walls of the structure are respectively slidably connected to the interior of two sliding grooves. A screw is provided at the center of the upper end face of the gate structure. The upper end of the screw passes through the upper inner wall of the retaining frame and extends to the upper end. An adjustment device is sleeved on the side wall of the screw at the upper end of the retaining frame. The gate structure includes a gate, which is composed of two corrosion-resistant layers, two reinforcing layers and one intermediate layer. Reinforcing layers are provided on the front and rear sides of the intermediate layer, and corrosion-resistant layers are provided on the other side of the two reinforcing layers. Multiple grooves are provided on the front and rear side walls of the gate.

[0006] The above technical solution increases the contact area with water by setting multiple grooves on the front and rear side walls of the gate, thus dispersing the pressure of water on the gate. At the same time, the corrosion-resistant layer and the reinforcement layer are set to improve the corrosion resistance and overall strength of the gate, reducing the overall service life caused by environmental factors. Meanwhile, the internal concrete intermediate layer increases the overall weight, making it more stable during use.

[0007] Furthermore, the salvage structure includes a collection trough, which is located at the center of the upper end face of the base plate near the front edge. Telescopic devices are fixedly connected to the center of the lower inner wall of the collection trough near both side edges. A storage frame is provided inside the collection trough. The output ends of the two telescopic devices are fixedly connected to the lower end face of the storage frame. Metal filter screens are connected through the front and rear side walls of the storage frame. Discharge ports are provided at the center of the front side wall of the base plate near both sides. The two discharge ports pass through the front side wall of the base plate and lead to the interior of the collection trough. A baffle is provided on the upper end face of the base plate near the rear side of the collection trough.

[0008] The above technical solution allows for the collection and treatment of sediment in the water flow through a collection trough and a baffle. The sediment is collected in a combination of a collection frame and a metal filter. After a period of use, two telescopic devices lift the collection frame upwards, making it easier for dredging personnel to clean the sediment inside. As it rises, a small amount of sediment falls into the collection trough. When the two telescopic devices descend, they create downward pressure inside the collection trough, causing the sediment to be discharged through the outlet without affecting the next collection.

[0009] Furthermore, multiple connecting buckles are fixedly connected to the center of each of the two side walls of the retaining frame;

[0010] The above technical solutions enable one-piece prefabricated products to be easily installed and connected on-site, improving installation efficiency and reducing hassle.

[0011] Furthermore, the stop block is triangular in shape and made of cast iron;

[0012] The above technical solution ensures that the sand and gravel in the water flow fall into the collection tank through the inclined baffle.

[0013] Furthermore, the corrosion-resistant layer is made of cast iron, and its surface is coated with polyurethane coating.

[0014] The above technical solution has good wear resistance and corrosion resistance. The surface is coated with polyurethane coating, which can further improve the overall corrosion resistance and thus increase the service life.

[0015] Furthermore, the reinforcing layer is made of carbon steel;

[0016] The above technical solution has high strength and hardness and can withstand greater impact.

[0017] Furthermore, the intermediate layer is made of concrete;

[0018] The above technical solutions can increase the overall weight of the gate, ensuring stability during use.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, by setting a gate structure, multiple grooves are set on the front and rear side walls of the gate to increase the contact area with water and disperse the pressure of water on the gate. At the same time, a corrosion-resistant layer and a reinforcing layer are set to improve the corrosion resistance and overall strength of the gate, reduce the reduction of the overall service life due to environmental impact, and the internal concrete intermediate layer increases the overall weight, making it more stable during use.

[0021] 2. In this utility model, by setting the overall structure as prefabricated, point-to-point installation is achieved, reducing construction difficulty and improving on-site construction efficiency.

[0022] 3. In this utility model, by setting up a salvage structure, the mud and sand in the water flow are collected and processed by the cooperation of the collection trough and the baffle. The mud and sand are collected in the combination structure of the storage frame and the metal filter screen. After a period of use, the storage frame is lifted upward by two telescopic devices, so that the salvage personnel can clean the mud and sand inside. When it is raised, a small amount of mud and sand will fall into the inside of the collection trough. When the two telescopic devices descend, they generate a downward pressure on the inside of the collection trough, thereby discharging the mud and sand inside through the discharge port, without affecting the next collection and use.

[0030] Reference Figure 1-4This utility model provides an embodiment of a corrosion-resistant sluice gate structure for a water conservancy pumping station, comprising a base plate 8, a retaining frame 1 at the center of the upper end face of the base plate 8, diagonal braces 7 fixedly connected to the front and rear side walls near the side edges of the retaining frame 1, the lower ends of the four diagonal braces 7 fixedly connected to the upper end face of the base plate 8, a retrieval structure 6 at the front side edge of the center of the upper end face of the base plate 8, sliding grooves 4 at the center of the two inner side walls of the retaining frame 1, a gate structure 5 inside the retaining frame 1 between the two sliding grooves 4, the two side walls of the gate structure 5 slidingly connected to the two sliding grooves 4, a screw 3 at the center of the upper end face of the gate structure 5, the upper end of the screw 3 penetrating the upper inner wall of the retaining frame 1 and extending to the upper end, and an adjustment device sleeved on the side wall of the screw 3 at the upper end of the retaining frame 1. 2. The gate structure 5 includes a gate 502, which consists of two corrosion-resistant layers 503, two reinforcing layers 504, and an intermediate layer 505. The intermediate layer 505 has reinforcing layers 504 on its front and rear sides, and corrosion-resistant layers 503 on the other side of the two reinforcing layers 504. Multiple grooves 501 are provided on the front and rear side walls of the gate 502. By providing multiple grooves 501 on the front and rear side walls of the gate 502, the contact area with water is increased, and the pressure of water on the gate 502 is dispersed. At the same time, the corrosion-resistant layers 503 and the reinforcing layers 504 are provided to improve the corrosion resistance and overall strength of the gate 502, and reduce the reduction of the overall service life due to environmental impact. Meanwhile, the intermediate layer 505, made of concrete, increases the overall weight, making it more stable during use.

[0031] The salvage structure 6 includes a collection trough 602, which is located at the center of the upper end face of the base plate 8 near the front edge. Telescopic devices 605 are fixedly connected to the center of the lower inner wall of the collection trough 602 near both side edges. A storage frame 604 is provided inside the collection trough 602. The output ends of the two telescopic devices 605 are fixedly connected to the lower end face of the storage frame 604. Metal filter screens 606 are respectively connected through the front and rear side walls of the storage frame 604. Discharge ports 603 are respectively located at the center of the front side wall of the base plate 8 near both sides. The two discharge ports 603 penetrate the front side wall of the base plate 8 and lead to the interior of the collection trough 602, close to the collection... A baffle 601 is provided on the upper surface of the rear bottom plate 8 of the trough 602. The trough 602 and the baffle 601 work together to collect and process the mud and sand in the water flow. The mud and sand are collected in the combination structure of the storage frame 604 and the metal filter screen 606. After a period of use, the storage frame 604 is lifted upward by two telescopic devices 605, which makes it easier for the salvage personnel to clean the mud and sand inside. When it is lifted, a small amount of mud and sand will fall into the inside of the collection trough 602. When the two telescopic devices 605 descend, they generate a downward pressure on the inside of the collection trough 602, thereby discharging the mud and sand inside through the discharge port 603, without affecting the next collection and use.

The corrosion-resistant layer 503 is made of cast iron and coated with polyurethane, which has good wear resistance and corrosion resistance. The polyurethane coating further improves the overall corrosion resistance, thereby increasing the service life. The reinforcing layer 504 is made of carbon steel, which has high strength and hardness and can withstand greater impact. The intermediate layer 505 is made of concrete, which increases the overall weight of the gate 502 and ensures stability during use.

[0033] Working Principle: This utility model is a corrosion-resistant sluice gate structure for a water conservancy pumping station. The collection trough 602, in conjunction with the baffle 601, collects and processes sediment in the water flow. The sediment is collected in a combination structure of a storage frame 604 and a metal filter screen 606. After a period of use, two telescopic devices 605 lift the storage frame 604 upwards, facilitating the cleaning of the sediment by dredging personnel. As it rises, a small amount of sediment falls into the collection trough 602. When the two telescopic devices 605 descend, they exert downward pressure on the inside of the collection trough 602, thus pushing the sediment downwards. The water is discharged through outlet 603 without affecting the next collection and use. Multiple grooves 501 are provided on the front and rear side walls of the gate 502 to increase the contact area with water and disperse the pressure of water on the gate 502. At the same time, a corrosion-resistant layer 503 and a reinforcing layer 504 are provided to improve the corrosion resistance and overall strength of the gate 502 and reduce the reduction of the overall service life due to environmental impact. Meanwhile, the internal concrete intermediate layer 505 increases the overall weight, making it more stable during use. By setting the overall structure as prefabricated, point-to-point installation is achieved, reducing construction difficulty and improving on-site construction efficiency.
