Description

Technical Field

[0001] This application relates to the technical field of grid interception plates, and in particular to a grid interception plate for a water storage tank. Background Technology

[0002] Bar screens for stormwater storage tanks are mechanical filtration components installed at the inlet or internal water flow channels of stormwater storage tanks, combined sewer system storage tanks, and other storage facilities. Their core function is physical interception. Before stormwater and sewage enter the storage tank or are treated, they intercept large-particle suspended debris, solid impurities, and floating objects in the water, preventing debris from clogging the internal pipes, pumps, valves, and other equipment of the storage tank. This avoids the accumulation of impurities affecting the storage volume, reduces the operating load of subsequent treatment processes, and ensures the overall operational stability and safety of the storage tank.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In the prior art, large impurities and top-accumulated impurities are difficult to clean. Traditional grids are mostly flat fixed structures, and large impurities are easily stuck in the gaps between the grid mesh or accumulate on the top of the grid, forming blockages. Moreover, there is a lack of directional guidance mechanisms. After the impurities accumulate, they need to be manually inserted into the storage tank to clean them one by one, which is not only dangerous to operate, but also requires interrupting the operation of the storage tank. Utility Model Content

[0004] In order to guide, clean and collect large impurities, this application provides a bar screen for a storage tank.

[0005] This application provides a bar screen for a storage tank, which adopts the following technical solution: it includes a fixed frame, a connecting frame fixedly connected to the inner wall of the fixed frame, a bar screen fixedly connected to the inner wall of the connecting frame, a fixed frame fixedly connected to the top of the fixed frame, an arc-shaped fixed block fixedly connected to the right side of the inner wall of the fixed frame, a fixed box fixedly connected to the top of the fixed frame, and a diversion plate fixedly connected to the top of the fixed box. A movable plate is slidably connected to the outer wall of the grid. A rotating groove is provided at the bottom of the movable plate. A rotating block is rotatably connected to the inner wall of the rotating groove. A slot is provided on the right side of the rotating block. A rotating wheel is rotatably connected to the inner wall of the slot. The rotating wheel is adapted to the arc-shaped fixed block.

[0006] Optionally, a motor is fixedly connected to the right side of the fixed box, and a bidirectional threaded rod is fixedly connected to the output end of the motor on the left side. A movable block is threadedly connected to the outer wall of the bidirectional threaded rod, and the outer wall of the movable block is slidably connected to the inner wall of the fixed box.

[0007] Optionally, a connecting plate is fixedly connected to the bottom of the movable block, and the bottom of the connecting plate is fixedly connected to the top of the movable block.

[0008] Optionally, a cleaning scraper is fixedly connected to the outer wall of the movable plate, and the inner wall of the cleaning scraper is slidably connected to the outer wall of the grid.

[0009] Optionally, a limiting plate is fixedly connected to the inner wall of the fixed box, and the inner wall of the limiting plate is rotatably connected to the middle of the outer wall of the bidirectional threaded rod.

[0010] Optionally, a baffle is fixedly connected to the inner wall of the slot, and the top of the baffle contacts the bottom of the rotating block.

[0011] Optionally, a collection box is fixedly installed on the right side of the fixed frame, and the right side of the collection box is in contact with the left side of the inner wall of the fixed frame.

[0012] Optionally, the number of rotating blocks is several, and the several rotating blocks are arranged in a horizontal array.

[0013] In summary, this application includes the following beneficial technical effects: 1. This utility model uses components such as rotating blocks, rotating wheels, and arc-shaped fixed blocks arranged in a horizontal array. The rotating blocks and rotating wheels roll along the arc-shaped surface of the arc-shaped fixed blocks, causing the rotating blocks to rotate upward around the rotating groove at the bottom of the moving plate, generating an upward pushing force. This guides large impurities accumulated at the top of the grid into the collection box, preventing impurities from getting stuck in the grid gaps or accumulating at the top. The collection box and the fixed frame are detachably connected. When impurities accumulate to a certain amount, there is no need to stop the machine and disassemble the grid body; simply remove the collection box and empty it. This shortens the operation time, reduces the frequency of manual entry into the storage tank, lowers the risks of high-altitude and underwater operations, and reduces maintenance labor costs. It is suitable for large storage tanks or deep-water conditions.

[0014] 2. This utility model, by incorporating components such as a motor, a bidirectional threaded rod, and a moving block, allows the motor to drive the bidirectional threaded rod to rotate. Under the limiting action of the inner wall of the fixed box, the moving block causes the connecting plate and the moving plate to slide back and forth along the length of the grille. The cleaning scraper moves synchronously against the outer wall of the grille, which can quickly scrape away small impurities such as mud, sand, and leaf debris adhering to the surface of the grille, preventing impurities from forming a clogging layer. Compared with traditional manual cleaning, this structure can increase the cleaning frequency of the grille and maintain its unobstructed flow. Attached Figure Description

Detailed Implementation

[0017] The following is in conjunction with the appendix Figures 1-5 This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0018] This application discloses a grating interceptor plate for a water storage tank. For example... Figure 1 , Figure 2 , Figure 3 As shown, the device includes a fixed frame 1, with a connecting frame 11 fixedly connected to the inner wall of the fixed frame 1. Both sides of the connecting frame 11 are chamfered to facilitate the falling of garbage. A grid 13 is fixedly connected to the inner wall of the connecting frame 11. A fixed frame 12 is fixedly connected to the top of the fixed frame 1. An arc-shaped fixing block 32 is fixedly connected to the right side of the inner wall of the fixed frame 1. The arc-shaped fixing block 32 is paired with the rotating wheel 31, which allows the box to rotate after the rotating block 31 moves continuously to this position, lifting the garbage on top of the grid 13 and the garbage inside the grid. A fixed box 2 is fixedly connected to the top of the fixed frame 12. A diversion plate 121 is fixedly connected to the top of the fixed box 2. The diversion plate 121 can divert sewage to prevent it from remaining on the fixed box 2. At the same time, the diversion plate 121 can also protect the motor 21.

[0019] In this embodiment, a movable plate 23 is slidably connected to the outer wall of the grille 13. There are two movable plates 23, and the initial state of the two movable plates 23 is that they are in contact through the cleaning scraper 231 to avoid large impurities falling between them. A rotating groove is opened at the bottom of the movable plate 23, and a rotating block 3 is rotatably connected to the inner wall of the rotating groove. A slot is opened on the right side of the rotating block 3, and a rotating wheel 31 is rotatably connected to the inner wall of the slot. The setting of the rotating wheel 31 can reduce the friction between it and the arc-shaped fixed block 32 and improve the service life of the device. The rotating wheel 31 is adapted to the arc-shaped fixed block 32.

[0020] A limiting plate 24 is fixedly connected to the inner wall of the fixed box 2, and the inner wall of the limiting plate 24 is rotatably connected to the middle of the outer wall of the bidirectional threaded rod 211.

[0021] A motor 21 is fixedly connected to the right side of the fixed box 2. A bidirectional threaded rod 211 is fixedly connected to the output end of the motor 21 on the left side. A moving block 22 is threadedly connected to the outer wall of the bidirectional threaded rod 211. The outer wall of the moving block 22 is slidably connected to the inner wall of the fixed box 2. The moving block 22 is restricted by the fixed box 2 and threadedly connected to the bidirectional threaded rod 211, so that it can move axially back and forth along the fixed box 2.

[0022] Please see Figure 5 As shown, a baffle 34 is fixedly connected to the inner wall of the slot. The baffle 34 can restrict the rotating block 3. The top of the baffle 34 is in contact with the bottom of the rotating block 3.

[0023] A connecting plate 221 is fixedly connected to the bottom of the movable block 22, and the bottom of the connecting plate 221 is fixedly connected to the top of the movable plate 23.

[0024] Please see Figure 4 As shown, a collection box 33 is fixedly installed on the right side of the fixed frame 1. The right side of the collection box 33 is in contact with the left side of the inner wall of the fixed frame 1. There are several rotating blocks 3, which are arranged in a horizontal array.

[0025] A cleaning scraper 231 is fixedly connected to the outer wall of the movable plate 23. There are several cleaning scrapers 231 arranged in a horizontal array. The cleaning scrapers 231 are provided on both sides of the movable plate 23. The inner wall of the cleaning scraper 231 is slidably connected to the outer wall of the grille 13.

[0026] The implementation principle of a bar screen for a water storage tank in this application embodiment is as follows: when rainwater and sewage flow into the water storage tank from the inlet, they first pass through the diversion plate 121 on the top of the fixed box 2. The diversion plate 121 disperses the water flow through multiple sets of inclined guide channels, preventing high-velocity water from directly impacting the surface of the grid 13. The dispersed water flows into the frame composed of the fixed frame 1 and the connecting frame 11. The grid 13 classifies and intercepts impurities in the water flow. Large impurities such as branches and plastic bottles are blocked on the outside of the grid 13 or accumulate on the top. Small impurities such as silt and fallen leaves adhere to the surface of the grid 13. The filtered water enters the regulating tank through the grid 13, completing the initial water pretreatment. When impurities adhere to the mesh of the grid 13, causing the water flow velocity to decrease, the power is turned on by the motor 21. The left output end drives the bidirectional threaded rod 211 to rotate inside the fixed box 2. The limiting plate 24 on the inner wall of the fixed box 2 provides support and restriction for the middle part of the bidirectional threaded rod 211. The two moving blocks 22 on the outer wall of the bidirectional threaded rod 211 slide back and forth along the inner wall of the fixed box 2 under the action of threaded transmission. The two connecting plates 221 at the bottom of the two moving blocks 22 are in sync with each other. The two moving plates 23 slide along the outer wall of the grid 13. The cleaning scrapers 231 on the outer side of the moving plates 23 are in close contact with the surface of the grid 13, scraping away the small impurities on the mesh of the grid 13. At the same time, they push the impurities accumulated on the top of the grid 13 to move to both sides of the connecting frame 11. Several cleaning scrapers 231 push the large impurities on both sides to move to both sides of the connecting frame 11. The continuous pushing will cause the large impurities to accumulate on both sides of the connecting frame 11. When the rotating wheel 31 at the bottom of the rotating block 3 rolls upward along the arc surface of the arc-shaped fixed block 32, the upward thrust generated will drive the rotating block 3 to rotate around the rotating groove at the bottom of the moving plate 23, forming an inclined lifting effect. At the same time, since both sides of the fixed frame are chamfered, it can ensure that the impurities slide along the guide channel to the collection box 33. When the impurities in the collection box 33 reach the upper limit of the capacity, the motor 21 is turned off to stop the cleaning operation. The connection structure between the collection box 33 and the fixed frame 1 is disassembled, the impurities are emptied and reinstalled to restore the directional collection function.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
