Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering and environmental protection equipment technology, specifically to a basket grid for pumping stations. Background Technology

[0002] With the acceleration of urbanization and the vigorous development of industrial production, water resource allocation and sewage treatment are facing unprecedented challenges. Pumping station equipment, as a key water conservancy facility, plays a crucial role in these challenges. Widely used in municipal water supply and drainage, sewage treatment, industrial production, and many other fields, pumping station equipment is a core device for ensuring the rational allocation of water resources, effective sewage treatment, and the smooth operation of various production processes. Its core function is to lift, transport, and control water flow, ensuring that water flows according to predetermined paths and requirements.

[0003] Traditional pump station equipment typically uses a single-layer basket screen structure with a relatively fixed installation position. The inlet pipe is usually directly connected to the top of the fixed screen, and water flows from top to bottom into the basket screen for filtration. However, this traditional design has many drawbacks. On the one hand, when it is necessary to clean debris from inside the basket screen, the entire basket screen often needs to be manually removed from the pump well for external cleaning. This operation relies heavily on manpower, and the pump station needs to be shut down during the cleaning process, affecting overall work efficiency. If the pump station is not shut down, the water flow will carry debris into the pump well. The integrated pump well structure is complex, and the debris flowing into the well chamber will be more difficult to clean, further increasing the difficulty and cost of maintenance. On the other hand, during filtration, the traditional basket screen, due to the unidirectional water flow, easily causes some debris to accumulate on the screen surface, reducing the filtration effect. It is also difficult to effectively clean stubborn debris attached to the inner wall of the screen. In the long run, this will not only affect the filtration efficiency of the pump station but may also threaten the normal operation of the pump station, increasing the risk of equipment failure and failing to meet the requirements of modern pump stations for efficient and stable operation. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing technologies by providing a basket grid for pumping stations, thereby overcoming the aforementioned defects.

[0005] To achieve the above objectives, this utility model designs a basket grille for pump stations, comprising a grille box body, a grille end plate at one end of the grille box body extending downwards, a window on the grille end plate, a sliding plate that slides up and down inside the window, a through hole on the sliding plate, an inlet pipe installed in the through hole, and a guide bend connected to the bottom of the grille box body; when the grille box body is in operation, the inlet pipe is connected to the inner cavity of the grille box body; when the grille box body is being cleaned, the inlet pipe is connected to the guide bend.

[0006] Preferably, the grating end plate is vertically equipped with guide rods on both sides of the window, and the sliding plate is provided with sliding holes that cooperate with the guide rods. The cooperation of the guide rods and sliding holes allows the sliding plate to slide smoothly up and down, ensuring accurate connection between the water inlet pipe and the inner cavity of the grating box or the guide bend, thereby improving the reliability and operational stability of the device.

[0007] Preferably, the top and bottom of the slide plate are respectively provided with a first flexible mesh and a second flexible mesh. The top and bottom ends of the first flexible mesh are connected to the grid end plate located at the top of the window and the top of the slide plate, respectively. The top and bottom ends of the second flexible mesh are connected to the bottom of the slide plate and the grid end plate located at the bottom of the window, respectively. Multiple hanging rings are provided on both sides of the first and second flexible meshes, and the hanging rings are slidably attached to the guide rod. The first and second flexible meshes effectively prevent debris inside the grid box from scattering during cleaning, keeping the cleaning area clean and improving cleaning efficiency and maintenance convenience.

[0008] Preferably, the grid end plate includes an upper end plate and a lower end plate, with opening windows respectively provided at the bottom of the upper end plate and the top of the lower end plate, and the two opening windows are connected to form the window when the upper end plate and the lower end plate are connected to form the grid end plate.

[0009] Preferably, a baffle plate is installed at the water inlet end of the guide bend. The baffle plate has a circular hole for fitting onto the water inlet end of the guide bend. The baffle plate has a limiting groove and a clearance opening at the bottom and top of the circular hole. The sliding plate has a limiting block and a water-blocking protrusion that cooperate with the limiting groove and the clearance opening. By cooperating with the limiting groove on the baffle plate and the water-blocking protrusion with the clearance opening, a better sealing effect can be achieved when the water inlet pipe and the guide bend are connected, preventing water leakage.

[0010] Preferably, the bar screen includes a U-shaped bar screen, with a top plate and a bottom plate at the top and bottom of the U-shaped bar screen. An end plate is provided at the U-shaped end of the bar screen, and the end of the top plate is hinged to the top of the end plate. The U-shaped bar screen design helps to deflect water flow, increasing the contact time between the water flow and the bar screen, thus improving filtration efficiency. The hinged top plate facilitates opening and closing, making it convenient to clean and maintain the interior of the bar screen.

[0011] Preferably, the top edge of the grating top plate is provided with multiple pull tabs. The pull tabs make it easier for operators to lift the grating top plate, saving time and effort and improving the convenience and efficiency of operation.

[0012] Preferably, the bottom plate of the grid is provided with a through hole adapted to the flow guide bend; the water inlet end of the flow guide bend abuts against the second flexible mesh.

[0013] Preferably, the side wall of the bar screen is provided with a positioning sleeve. The positioning sleeve helps to stably position the bar screen in the pump well, reduces the shaking caused by water flow impact, and ensures the stability of the filtration process.

[0014] Preferably, the guide bend is L-shaped.

[0015] The beneficial effects of this utility model are:

[0016] This utility model relates to a basket grid for pumping stations. By setting up a sliding plate and a double-layer flexible mesh, it realizes the cyclical operation of water intake, filtration, cleaning and resetting, which effectively improves the efficiency and effect of sewage filtration in pumping stations. At the same time, it facilitates the cleaning and maintenance of impurities and can meet the needs of modern pumping stations for efficient and stable operation.

[0017] This patented basket grille design for pump stations utilizes a sliding plate. During operation, the inlet pipe connects to the inner cavity of the grille box, allowing wastewater to pass through the U-shaped grille for filtration, effectively intercepting larger debris and improving filtration efficiency. During cleaning, the sliding plate slides down, connecting the inlet pipe to a guide bend, ensuring a continuous flow of wastewater to the bottom of the grille box. This uninterrupted filtration process avoids the need to pause drainage during cleaning of traditional basket grilles, thus guaranteeing the efficient and stable operation of the pump station.

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Example

[0038] like Figures 1-5 The basket grating shown for a pumping station includes a grating box 1. One end of the grating box 1 is provided with a grating end plate 2, which extends downward. A window 21 is opened on the grating end plate 2, and a sliding plate 3 that slides up and down is provided inside the window 21. A through hole 31 is opened on the sliding plate 3, and a water inlet pipe 4 is installed in the through hole 31. An L-shaped guide bend 5 is connected to the bottom of the grating box 1. When the grating box 1 is working, the water inlet pipe 4 is connected to the inner cavity of the grating box 1. When the grating box 1 is being cleaned, the water inlet pipe 4 is connected to the guide bend 5.

[0039] The grid end plate 2 is equipped with guide rods 24 on the inner side of the window 21, and the slide plate 3 is equipped with sliding holes 32 that cooperate with the guide rods 24. The top and bottom of the slide plate 3 are respectively equipped with a first flexible mesh 6 and a second flexible mesh 7. The top and bottom ends of the first flexible mesh 6 are connected to the top of the grid end plate 2 in the window 21 and the top of the slide plate 3, respectively. The top and bottom ends of the second flexible mesh 7 are connected to the bottom of the slide plate 3 and the bottom of the grid end plate 2 in the window 21, respectively. Multiple hanging rings 241 are provided on both sides of the first flexible mesh 6 and the second flexible mesh 7, and the hanging rings 241 are slidably hooked onto the guide rods 24.

[0040] A baffle plate 51 is installed at the water inlet end of the guide bend 5. The baffle plate 51 has a round hole for fitting into the water inlet end of the guide bend 5. The baffle plate 51 has a limiting groove 511 and a clearance opening 512 at the bottom and top of the round hole. The slide plate 3 has a limiting block and a water blocking protrusion 33 that cooperate with the limiting groove 511 and the clearance opening 512.

[0041] The bar screen 1 includes a U-shaped bar screen 11. The top and bottom of the U-shaped bar screen 11 are provided with a top plate 12 and a bottom plate 13. A bar screen end plate 2 is provided at the U-shaped opening end of the U-shaped bar screen 11. The end of the top plate 12 is hinged to the top of the end plate 2 via a hinge 15. Multiple lugs 121 are provided on the top edge of the top plate 12. The bottom plate 13 has through holes adapted to a guide bend 5; the inlet end of the guide bend 5 abuts against a second flexible mesh 7. Positioning sleeves 14 are provided on the side walls of the bar screen 1. The end plate 2 includes an upper end plate 22 and a lower end plate 23. Opening windows are provided at the bottom of the upper end plate 22 and the top of the lower end plate 23, respectively. When the upper end plate 22 and the lower end plate 23 are connected to form the end plate 2, the two opening windows are connected to form a window 21.

[0042] The following describes the manufacturing process of this basket grille:

[0043] I. Normal Filtration Stage

[0044] The worker attaches the lifting rope to the pull lug 121, lowers the bar screen 1 into the pump well, inserts the positioning sleeve 14 into the slide rod inside the pump well, and connects the water inlet pipe 4 into the through hole 31 of the slide plate 3. At this time, the slide plate 3 is at the top of the window 21. The bar screen 1 is in working condition, and the water inlet pipe 4 is connected to the inner cavity of the bar screen 1.

[0045] Wastewater flows into the bar screen 1 from the inlet pipe 4. Since the bar screen 1 includes a U-shaped bar screen 11, the wastewater flows through the U-shaped bar screen 11, where larger debris is intercepted by the U-shaped bar screen 11.

[0046] The design of the U-shaped bar 11 creates a deflection effect in the water flow, increasing the contact time between the water flow and the bar, and improving filtration efficiency. Under the guidance of the U-shaped bar 11, the water flow is evenly distributed within the bar box 1, avoiding localized overload.

[0047] During the filtration process, the positioning sleeve 14 on the side wall of the bar screen 1 plays a role in stabilizing the position of the bar screen 1, preventing the bar screen 1 from shaking due to factors such as water flow impact, and ensuring that the filtration process proceeds stably.

[0048] II. Cleanup and Preparation Phase

[0049] When it is necessary to clean debris from inside the grille box 1, the operator lifts the grille top plate 12 upwards using the pull lug 121. As the grille top plate 12 is lifted, the slide plate 3 slides downwards along the guide rod 24.

[0050] As the slide plate 3 moves downwards, the inlet pipe 4 gradually disengages from the inner cavity of the bar screen 1, while simultaneously connecting with the guide bend 5. The limiting block on the slide plate 3 inserts into the limiting groove 511. At this time, sewage continues to flow into the bottom of the bar screen 1 through the inlet pipe 4 and the guide bend 5, ensuring continuous sewage treatment at the pumping station and avoiding the problem of having to stop draining the inlet pipe during traditional bar screen cleaning.

[0051] As the skateboard 3 slides down, the first flexible mesh 6 gradually contracts and folds under the action of the skateboard 3, and the hanging ring 241 slides on the guide rod 24.

[0052] The top plate 12 of the grating continues to be lifted upwards, raising the entire grating box 1 out of the pump well. Due to the design of the guide bend 5, sewage can still enter the bottom of the grating box 1 through the inlet pipe 4 and the guide bend 5 during the lifting process, without affecting the normal operation of the pump station. Workers open the top plate 12 of the grating and remove any debris from inside the grating box 1.

[0053] III. Reset and Restart Preparation

[0054] After cleaning, the bar screen 1 is returned to its original position in the pump well. During the descent of the bar screen 1, the slide plate 3 gradually slides upward under the action of the guide rod 24, returning to its initial uppermost position. The inlet pipe 4 is reconnected to the inner cavity of the bar screen 1, while the connection between the inlet pipe 4 and the guide bend 5 is severed.

[0055] The system returns to normal filtration status. At this point, the bar screen 1 is ready to resume normal filtration operations, and the entire sewage filtration system of the pumping station returns to normal operation, effectively improving the efficiency and effectiveness of sewage filtration. It also facilitates the cleaning and maintenance of impurities, meeting the needs of modern pumping stations for efficient and stable operation.

[0056] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
