Description

Technical Field

[0001] This utility model relates to the field of sewage treatment technology, and more specifically, to an adjustable stacked beam gate. Background Technology

[0002] In wastewater treatment, to improve effluent quality, the effluent from the secondary sedimentation tank needs to be pumped to the filter tank. After filtration, the effluent then flows by gravity from the filter tank to the contact disinfection tank. When the wastewater treatment load increases, the pumping capacity of the pump needs to be increased. At this time, the effluent channel of the filter tank may overflow, posing a risk of flooding. If the pumping capacity is not increased, the secondary sedimentation tank will also be at risk of overflow. However, the effluent weirs in the existing filter tanks are all cement weirs with non-adjustable height. When the water level in the filter tank is too high and the amount of water flowing into the tank is greater than the amount of water flowing out of the filter tank by gravity, overflow will occur, posing a safety hazard.

[0003] In existing technologies, stacked beam gates can be used to replace the outlet weir to achieve timely gate opening and discharge. However, the water level adjustment of existing stacked beam gates is not flexible, and it is easy for the discharge water level to be too low or too high, which is not convenient to use. Utility Model Content

[0004] To overcome the shortcomings of the prior art, such as the inflexible water level adjustment and inconvenience of using stacked beam gates, this utility model provides an adjustable stacked beam gate that facilitates the adjustment of the discharge height, is easy to use, and also avoids filter overflow.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an adjustable stacked beam gate, comprising: a first side wall, a second side wall, a first sliding groove and a second sliding groove respectively fixed on the first side wall and the second side wall, a base plate disposed between the first sliding groove and the second sliding groove, and a plurality of first weir plates and a plurality of second weir plates disposed above the base plate, wherein the heights of the first weir plates and the second weir plates are not the same, and both ends of the first weir plates and the second weir plates are slidably connected to the first sliding groove and the second sliding groove respectively.

[0006] The first and second chutes are fixed to the first and second side walls, respectively, to restrict and fix the first and second weir plates. A base plate is positioned between the first and second chutes at the bottom. The first and second weir plates are stacked on top of the base plate, with their ends engaged within the chutes. Sealing plates are also provided at the top of the base plate and between the first and second weir plates to ensure sealing between components. This allows the first and second weir plates to block water. Since the first and second weir plates are at different heights, they can be randomly combined depending on their stacking positions in different pools. When drainage is needed, either the first or second weir plate can be slid upwards and removed according to the desired drainage height, achieving drainage at various heights for ease of use. Furthermore, the sealing plates are made of rubber or plastic, and their length is the same as the length of the first and second weir plates.

[0007] Preferably, handles are provided on the sides of both ends of the first weir plate and the second weir plate.

[0008] The addition of handles facilitates the lifting of the first or second weir plate. Handles at both ends ensure stability during lifting, guaranteeing operational safety. Specifically, the handles can be horizontal bars, hooks, inverted U-shaped connecting rods, curved plates, etc.

[0009] Preferably, the handles are respectively provided on different sides at both ends of the first weir plate and the second weir plate.

[0010] The handles are located on different sides at both ends, that is, at opposite corners, so that the force is more evenly distributed and more stable when lifting.

[0011] Preferably, the sealing plate is fixed to the bottom of the first weir plate and the second weir plate respectively.

[0012] The sealing plate is fixedly connected to the first and second weir plates, which improves the sealing performance and facilitates use.

[0013] Preferably, it also includes countersunk screws and nuts. The sealing plate is provided with countersunk holes. The countersunk screws are disposed in the countersunk holes and pass through the first weir plate or the second weir plate to connect with the nuts and thus fix the sealing plate.

[0014] Specifically, the sealing plate is fixed to the bottom of the first and second weir plates by countersunk screws and nuts. The countersunk screws do not protrude from the working surface of the sealing plate, thus ensuring the sealing performance and making it removable for easy maintenance and replacement.

[0015] Preferably, the edges and sides of both the first weir plate and the second weir plate are provided with reinforcing ribs.

[0016] The addition of reinforcing ribs enhances strength and increases the side surface area, allowing for wider installation of the sealing plate and ensuring a tight seal. The side reinforcing ribs can be achieved by bending the plate edges, resulting in even higher strength. Furthermore, both the first and second weir plates are made of stainless steel, as are the reinforcing ribs, which are welded to both plates.

[0017] Preferably, the first weir plate is disposed below the second weir plate, and the height of the first weir plate is higher than that of the second weir plate.

[0018] In most conventional cases, the higher first weir plate is placed at the bottom to reduce the number of connections between the first or second weir plates and ensure sealing, while the lower second weir plate is placed at the top to ensure flexibility in adjusting the discharge height.

[0019] Preferably, it further includes a bottom weir wall disposed between the first side wall and the second side wall, wherein the first chute, the second chute, the bottom plate, the first weir plate and the second weir plate are all disposed above the bottom weir wall.

[0020] For deeper pools, a bottom weir wall of fixed height is installed at the bottom to reduce the water-blocking pressure of the first and second weir plates, ensuring the sealing of the bottom of the pool and preventing insufficient sealing between the first and second weir plates due to high pressure at the bottom. At the same time, for existing weir walls, the upper part of the weir wall can be removed to make room for the installation of the first and second weir plates, which is convenient for modification and reduces costs.

[0021] Preferably, the upper part of the bottom weir wall is connected to an L-shaped protective plate, which covers the top surface and upper side surface of the bottom weir wall.

[0022] To improve sealing, a protective plate is installed, specifically covering one side of the bottom weir wall inside the pool. Furthermore, the protective plate is made of a corrosion-resistant metal material, such as corrosion-resistant alloy steel or stainless steel.

[0023] Preferably, the bottoms of the first chute and the second chute are connected to the side of the guard plate, and the bottom plate, the first weir plate and the second weir plate are located diagonally above the bottom weir wall.

[0024] This design allows the bottom weir wall to block the bottom of the first and second chutes, thus sharing the lateral thrust caused by water pressure and preventing the first and second chutes from tilting, thereby ensuring the overall stability of the stacked beam gate.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. Use first and second weir plates of different heights to block water. For pools with different discharge requirements, multiple discharge heights can be set by randomly stacking the first and second weir plates. This ensures both convenient discharge and arbitrary customization of discharge height, making it easy to use.

[0027] 2. A bottom weir wall is installed below the first and second weir plates to share the water-blocking pressure of the first and second weir plates, ensuring the overall sealing and stability of the stacked beam valve while achieving adjustable discharge height. Attached Figure Description

[0036] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0037] Example 1

[0038] like Figure 1-2 As shown, an adjustable stacked beam gate includes: a first side wall 1, a second side wall 2, a first sliding groove 3 and a second sliding groove 4 respectively fixed on the first side wall 1 and the second side wall 2, a base plate 5 disposed between the first sliding groove 3 and the second sliding groove 4, and a plurality of first weir plates 6 and a plurality of second weir plates 7 disposed above the base plate 5. The first weir plates 6 and the second weir plates 7 have different heights, and both ends of the first weir plates 6 and the second weir plates 7 are slidably connected to the first sliding groove 3 and the second sliding groove 4 respectively.

[0039] The first chute 3 and the second chute 4 are respectively fixed to the first side wall 1 and the second side wall 2, used to restrict and fix the first weir plate 6 and the second weir plate 7. The bottom plate 5 is set between the first chute 3 and the second chute 4 and is located at the bottom. The first weir plate 6 and the second weir plate 7 are stacked on top of the bottom plate 5, and the two ends of the first weir plate 6 and the second weir plate 7 are stuck in the first chute 3 and the second chute 4. Sealing plates 8 are also provided at the top of the bottom plate 5 and between the first weir plate 6 and the second weir plate 7 to ensure the sealing between the components. Water can be blocked by the first weir plate 6 and the second weir plate 7. At the same time, the first weir plate 6 and the second weir plate 7 are at different heights. When used in pools at different times, the first weir plate 6 and the second weir plate 7 can be randomly combined according to different stacking positions. When drainage is required, the first weir plate 6 or the second weir plate 7 can be slid upwards and removed according to the drainage height, so as to achieve drainage functions at multiple heights and for convenient use. Furthermore, the sealing plate 8 is made of rubber or plastic, and the length of the sealing plate 8 is the same as the length of the first weir plate 6 and the second weir plate 7.

[0040] The beneficial effects of this embodiment are: by using first weir plates 6 and second weir plates 7 of different heights to block water, for pools with different discharge requirements, multiple discharge heights can be set according to the random stacking of first weir plates 6 and second weir plates 7, which ensures convenient discharge and also ensures that the discharge height can be arbitrarily customized, making it convenient to use.

[0041] Example 2

[0042] The difference between Example 1 and Example 2 is as follows:

[0043] like Figure 4-5 As shown, handles 9 are provided on the sides of both ends of the first weir plate 6 and the second weir plate 7. The handles 9 are respectively located on different sides of both ends of the first weir plate 6 and the second weir plate 7. The sealing plates 8 are fixed to the bottoms of the first weir plate 6 and the second weir plate 7. Figure 3 As shown, it also includes a countersunk screw 10 and a nut 11. The sealing plate 8 has a countersunk hole, and the countersunk screw 10 is disposed in the countersunk hole and passes through the first weir plate 6 or the second weir plate 7 to connect with the nut 11, thereby fixing the sealing plate 8. Figure 5 As shown, the edges and sides of the first weir plate 6 and the second weir plate 7 are provided with reinforcing ribs 12.

[0044] Handles 9 are provided for easy lifting of the first weir plate 6 or the second weir plate 7. The presence of handles 9 at both ends ensures stability during lifting, guaranteeing operational safety. Specifically, handles 9 can be horizontal bars, hooks, inverted U-shaped connecting rods, arc-shaped plates, etc. The handles 9 are positioned on opposite sides, i.e., diagonally, for more even and stable force distribution during lifting. The sealing plate 8 is fixedly connected to the first weir plate 6 and the second weir plate 7, improving sealing performance and facilitating use. The sealing plate 8 is fixed to the bottom of the first weir plate 6 and the second weir plate 7 using countersunk screws 10 and nuts 11. The countersunk screws 10 do not protrude from the working surface of the sealing plate 8, ensuring sealing performance and allowing for disassembly for easy maintenance and replacement. Reinforcing ribs 12 enhance strength and increase the side area, increasing the width of the sealing plate 8 and ensuring sealing performance. The side reinforcing ribs 12 can be achieved by bending the plate edges, resulting in higher strength. Furthermore, both the first weir plate 6 and the second weir plate 7 are made of stainless steel, and the reinforcing rib 12 is also made of stainless steel. The reinforcing rib 12 is welded onto the first weir plate 6 and the second weir plate 7.

[0045] like Figure 2 As shown in this embodiment, both sides of the first slide 3 and the second slide 4 are provided with connecting plates, and the connecting plates are provided with multiple holes. The first slide 3 and the second slide 4 are fixed to the first side wall 1 and the second side wall 2 by bolts.

[0046] The remaining features and working principles of this embodiment are the same as those of Embodiment 1.

[0047] Example 3

[0048] Based on Example 1 or Example 2, Example 1 or Example 2 are further defined, with the following differences:

[0049] like Figure 1-2 As shown, the first weir plate 6 is positioned below the second weir plate 7, and the height of the first weir plate 6 is higher than that of the second weir plate 7. It also includes a bottom weir wall 13 positioned between the first side wall 1 and the second side wall 2. The first chute 3, the second chute 4, the bottom plate 5, the first weir plate 6, and the second weir plate 7 are all positioned above the bottom weir wall 13. An L-shaped protective plate 14 is connected to the upper part of the bottom weir wall 13, covering the top surface and upper side surface of the bottom weir wall 13. The bottoms of the first chute 3 and the second chute 4 are connected to the side of the protective plate 14, and the bottom plate 5, the first weir plate 6, and the second weir plate 7 are located diagonally above the bottom weir wall 13.

[0050] In most conventional cases, the higher first weir plate 6 is placed at the bottom to reduce the number of connections between the first weir plate 6 and the second weir plate 7, ensuring sealing. The lower second weir plate 7 is placed at the top to ensure flexibility in adjusting the discharge height. For deeper pools, a bottom weir wall 13 of fixed height is installed at the bottom to reduce the water-blocking pressure on the first weir plate 6 and the second weir plate 7, fully ensuring the sealing of the bottom of the pool and preventing insufficient sealing between the first weir plate 6 and the second weir plate 7 due to high pressure at the bottom. Furthermore, for existing weir walls, the upper half can be removed to make room for the installation of the first weir plate 6 and the second weir plate 7, facilitating renovation and reducing costs. A protective plate 14 is installed to improve sealing; specifically, the protective plate 14 covers the bottom weir wall 13 on one side inside the pool. Further, the protective plate 14 is made of a corrosion-resistant metal material, such as corrosion-resistant alloy steel plate or stainless steel plate. This configuration allows the bottom weir wall 13 to block the bottom of the first slide 3 and the second slide 4, which can share the lateral thrust caused by water pressure, thereby preventing the first slide 3 and the second slide 4 from tilting and ensuring the overall stability of the stacked beam gate.

[0051] In this embodiment, the first side wall 1, the second side wall 2, and the bottom weir wall 13 are all cement walls.

[0052] In this embodiment, three first weir plates 6 and two second weir plates 7 are provided above the bottom plate 5.

[0053] The remaining working principles and processes of this embodiment are the same as those of Embodiment 1 or Embodiment 2.

[0054] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
