Description

Technical Field

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

[0002] Pumping stations are one of the effective engineering measures to solve the three major water resource problems of today: floods, droughts, and water environment deterioration. They bear the important responsibility of regional flood control, drainage, irrigation, water transfer and supply. They are mainly used for farmland irrigation and drainage, urban water supply and drainage and inter-basin water transfer. They play an irreplaceable role in the rational scheduling and management of water resources. Because the water quality supplied by pumping stations varies, filtration processes are usually installed in pumping stations.

[0003] The existing pumping station has a complex structure for cleaning the filter screen, making it inconvenient to quickly disassemble and clean the filter screen.

[0004] The existing patent (publication number: CN222120386U) describes a pump station structure for water conservancy projects. This utility model allows for easy disassembly and cleaning of the filter plate simply by turning the handle and pulling it upwards.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, when the filter plate and filter screen proposed in the aforementioned patents are moved upwards to remove the rectangular filter box, the impurities blocked on the surface of the filter screen are prone to rubbing against the rectangular filter box, causing the impurities to fall into the rectangular filter box, making it inconvenient to clean the impurities inside the rectangular filter box subsequently.

[0006] Therefore, a pump station structure for water conservancy projects is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a pump station structure for water conservancy projects that can solve the problem in existing patents where, when the filter plate and filter screen are moved upward to pull out the rectangular filter box, impurities blocked on the surface of the filter screen easily rub against the rectangular filter box, causing impurities to fall into the rectangular filter box, making it inconvenient to clean the impurities inside the rectangular filter box later.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a pumping station structure for a water conservancy project, comprising a pumping station base and a pump body, wherein a filter box is fixedly connected to the left side of the top of the pumping station base, an inlet pipe is fixedly connected to the left side of the filter box, the right side of the filter box is fixedly connected to the input end of the pump body, a filter mechanism is provided inside the filter box, and a limit mechanism is provided on the front side of the filter box.

[0009] The filtration mechanism includes a fixed frame, a filter screen, a sealing ring, and a baffle. The filter screen is fixedly connected inside the fixed frame. The front side of the fixed frame is fixedly connected to the rear side of the baffle. The front side of the sealing ring is fixedly connected to the rear side of the baffle. The rear side of the sealing ring is in close contact with the front side of the filter box. The water inlet pipe is located at the bottom of the filter screen.

[0010] Preferably, the inner wall of the filter box is fixedly connected with two limiting strips, and the fixing frame is movably inserted between the two limiting strips on opposite sides.

[0011] Preferably, handles are fixedly connected to both sides of the baffle.

[0012] Preferably, the limiting mechanism includes two pull rings, a limiting plate, two threaded holes, and two limiting posts. The bottom of the pull rings is fixedly connected to the top of the limiting plate. The threaded holes are opened inside the limiting plate. The limiting posts are threadedly connected to the inside of the threaded holes. The rear side of the limiting posts is in close contact with the front side of the baffle.

[0013] Preferably, a fixing frame is fixedly connected to the front side of the filter box, the limiting plate is movably inserted into the inside of the fixing frame, and a slot is provided on the top of the pump station base, the limiting plate is movably inserted into the inside of the slot.

[0014] Preferably, the front and rear sides of the left side of the filter box are inlaid with transparent tempered glass.

[0015] Preferably, fixing blocks are fixedly connected to both the front and rear sides of the pump station base, and a flange is fixedly connected to the surface of the water inlet pipe.

[0016] Preferably, the bottom of the limiting plate has chamfers on both the front and rear sides.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting up a filtration mechanism, ensures that impurities are intercepted and accumulate below the filter screen after the water inlet pipe is located at the bottom of the filter screen. When the fixing frame is pulled out, the impurities can be directly carried out, reducing friction with the filter box. Even if a small amount of impurities with weak adhesion fall off, they can be quickly removed through the large opening on the front side of the filter box. The fixing frame is precisely installed under the guidance of the limiting strip, and with the baffle and sealing ring, the airtightness of the filter box is ensured, preventing water leakage. This avoids the problem in existing patents where, when the filter plate and filter screen are moved upward to pull out the rectangular filter box, the impurities blocked on the surface of the filter screen easily rub against the rectangular filter box, causing the impurities to fall into the rectangular filter box, making it inconvenient to clean the impurities inside the rectangular filter box later.

[0019] 2. This application uses a limiting mechanism to lift the limiting plate by pulling the ring, allowing it to pass through the fixing frame and insert into the slot for initial positioning. The chamfered design at the bottom of the limiting plate facilitates quick insertion into the slot. After the limiting post is screwed into the threaded hole and tightened, it pushes the baffle to push the sealing ring to tightly fit the filter box, achieving a seal. During disassembly, the limiting post is loosened, and the limiting plate is removed by pulling the ring upwards, allowing the filter mechanism to be easily pulled out. The operation is simple and efficient, ensuring the stable installation of the filter screen and the sealing performance of the filter box. Attached Figure Description

[0027] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A pump station structure for a water conservancy project includes a pump station base 1 and a pump body 2. A filter box 3 is fixedly connected to the left side of the top of the pump station base 1. An inlet pipe 7 is fixedly connected to the left side of the filter box 3. The right side of the filter box 3 is fixedly connected to the input end of the pump body 2. A filter mechanism 5 is provided inside the filter box 3. A limit mechanism 4 is provided on the front side of the filter box 3.

[0030] The filtration mechanism 5 includes a fixed frame 501, a filter screen 502, a sealing ring 503, and a baffle 504. The filter screen 502 is fixedly connected inside the fixed frame 501. The front side of the fixed frame 501 is fixedly connected to the rear side of the baffle 504. The front side of the sealing ring 503 is fixedly connected to the rear side of the baffle 504. The rear side of the sealing ring 503 is in close contact with the front side of the filter box 3. The water inlet pipe 7 is located at the bottom of the filter screen 502.

[0031] In this embodiment: An extension pipe is bolted to flange 9, and water is pumped by external PLC-controlled pump body 2. Water flows into filter box 3 from inlet pipe 7. Impurities are intercepted below filter screen 502. During cleaning, loosen limit post 404, pull limit plate 402 out of slot 11 and fixing frame 8, and pull fixing frame 501 forward by handle 13. Impurities are carried out with filter screen 502. A small amount of fallen impurities can be removed from the larger opening on the front side of filter box 3. During installation, insert fixing frame 501 along limit strip 10 and insert limit plate 402. 02 Insert the fixing bracket 8 and slot 11, tighten the limiting post 404, and push the baffle 504 backward so that the sealing ring 503 seals between the baffle 504 and the filter box 3, so that the filter box 3 can perform filtration again. This solves the problem in the existing patent that when the filter plate and filter screen are moved upward to pull out the rectangular filter box, the impurities blocked on the surface of the filter screen are easily scratched by the rectangular filter box, causing the impurities to fall into the rectangular filter box, and it is inconvenient to clean the impurities inside the rectangular filter box later.

[0032] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, the inner wall of the filter box 3 is fixedly connected with two limit strips 10. The fixed frame 501 is movably inserted between the two limit strips 10 on opposite sides.

[0033] Specifically, such as Figure 4 As shown, handles 13 are fixedly connected to both sides of the baffle 504.

[0034] In this embodiment: two limiting strips 10 are fixed to the inner wall of the filter box 3, providing precise guidance and limiting for the fixed frame 501, ensuring that it will not deviate during installation, and ensuring the installation stability of the filter mechanism 5. The handles 13 on both sides of the baffle 504 are easy for operators to hold, providing a point of force when pulling out or pushing in the fixed frame 501, making the disassembly and installation of the filter screen 502 more labor-saving and convenient.

[0035] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the limiting mechanism 4 includes two pull rings 401, a limiting plate 402, two threaded holes 403, and two limiting posts 404. The bottom of the pull rings 401 is fixedly connected to the top of the limiting plate 402. The threaded holes 403 are opened inside the limiting plate 402. The limiting posts 404 are threadedly connected to the inside of the threaded holes 403. The rear side of the limiting posts 404 is in close contact with the front side of the baffle 504.

[0036] Specifically, such as Figure 1 , Figure 2 and Figure 6 As shown, a fixed frame 8 is fixedly connected to the front side of the filter box 3, and a limiting plate 402 is movably inserted into the inside of the fixed frame 8. A slot 11 is opened on the top of the pump station base 1, and the limiting plate 402 is movably inserted into the inside of the slot 11.

[0037] In this embodiment: In the limiting mechanism 4, the pull ring 401 facilitates the lifting of the limiting plate 402. The limiting plate 402 is initially positioned by inserting into the fixing bracket 8 and the slot 11. The threaded hole 403 cooperates with the limiting post 404. After tightening, the baffle 504 can be tightly pushed against the filter box 3, so that the sealing ring 503 forms an effective seal. The chamfer design at the bottom of the limiting plate 402 makes it easier to align and insert into the slot 11 and the fixing bracket 8, improving installation efficiency and convenience.

[0038] Specifically, such as Figure 1 As shown, transparent reinforced glass 6 is inlaid on the front and rear sides of the left side of the filter box 3.

[0039] Specifically, such as Figure 2 and Figure 6 As shown, fixing blocks 12 are fixedly connected to both the front and rear sides of the pump station base 1, and flanges 9 are fixedly connected to the surface of the water inlet pipe 7.

[0040] Specifically, such as Figure 5 As shown, chamfers are provided on both the front and rear sides of the bottom of the limiting plate 402.

[0041] In this embodiment: the transparent tempered glass 6 on the left side of the filter box 3 allows operators to visually observe the blockage and impurity accumulation of the internal filter screen 502 and perform timely maintenance; the fixing block 12 of the pump station base 1 can be fixedly connected to the installation position by external bolts to enhance the stability of the pump station base 1; the flange 9 of the water inlet pipe 7 facilitates quick connection of an external extension pipe for easy water pumping; and the chamfered bottom of the limiting plate 402 facilitates the insertion of the limiting plate 402 into the slot 11.

[0042] Working principle: Water is pumped through the flange 9 on the surface of the inlet pipe 7 using external bolts to connect an extension pipe. An external PLC controller controls the pump body 2 to operate. The PLC controller is a mature, publicly available technology and will not be elaborated upon here. Water flows from the inlet pipe 7 into the filter box 3. Because the inlet pipe 7 is located at the bottom of the filter screen 502, impurities in the water are intercepted by the filter screen 502 and accumulate below it, preventing impurities from entering the pump body 2. When the filter screen 502 has accumulated a large amount of impurities and needs cleaning, the limiting post 404 is rotated to disengage from the threaded hole 403, releasing the limiting post 404 from pushing against the baffle 504. Then, the pull ring 401 is pulled upwards, causing the limiting plate 402 to engage with the slot 11 and become fixed. The frame 8 is detached, and then the operator holds the handles 13 on both sides of the baffle 504 and pulls the fixing frame 501 forward from the filter box 3 along the limiting strip 10. At this time, the impurities attached to the bottom of the filter screen 502 can be directly carried out with the filter screen 502, avoiding the impurities attached to the bottom of the filter screen 502 from rubbing against the filter box 3. Even if a small amount of impurities fall into the filter box 3 due to weak adhesion, they can be quickly cleaned out because the front opening of the filter box 3 is large. This solves the problem in the existing patent where, when the filter plate and filter screen are moved upward to pull out the rectangular filter box, the impurities blocked on the surface of the filter screen easily rub against the rectangular filter box, causing the impurities to fall into the rectangular filter box, which is inconvenient for subsequent cleaning of the rectangular filter box. Regarding the issue of cleaning impurities inside the filter box, when installing the filter screen 502, first insert the fixing frame 501 into the filter box 3 along the two limiting strips 10. Use the limiting strips 10 to guide and limit the fixing frame 501 to ensure accurate installation. Next, lift the pull ring 401 at the top of the limiting plate 402, pass the bottom of the limiting plate 402 through the fixing bracket 8 on the front side of the filter box 3, and insert it into the slot 11 on the top of the pump station base 1 to initially fix the position of the limiting plate 402. The chamfers on the front and rear sides of the bottom of the limiting plate 402 facilitate the insertion of the limiting plate 402 into the slot 11. Then, screw the limiting post 404 into the threaded hole 403 on the limiting plate 402, and gradually tighten the limiting post 404 through the threaded connection. The limiting post 404 is pressed against the baffle 504, and the baffle 504 is pushed backward, causing the sealing ring 503 to fit tightly against the front of the filter box 3, forming a good sealing effect. This effectively prevents water leakage from the filter box 3 and ensures that water can only enter the pump body 2 through the filter screen 502. In addition, the transparent tempered glass 6 embedded on the left side of the filter box 3 allows the operator to observe the clogging and impurity accumulation of the filter screen 502 inside the filter box 3 at any time, and to judge in time whether the filter screen 502 needs to be cleaned. The fixing blocks 12 on the front and rear sides of the pump station base 1 can be fixed to the installation position by external bolts passing through the fixing blocks 12. It should be noted that the pump body 2 is a mature technology that has been published and will not be described in detail here.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
