[0037] The present invention is further described in detail below with reference to the accompanying drawings and specific implementation modes. DETAILED DESCRIPTION

[0038] like Figures 1 to 4 As shown, an embodiment of the present invention provides a soft-sealed regulating weir gate with adjustable compression, which belongs to the water level regulating gate installed in the water inlet channel or water distribution well in the environmental protection fields such as drinking water, domestic sewage and industrial sewage treatment. The soft-sealed regulating weir gate with adjustable compression can be used in sewage treatment facilities such as water distribution wells or water channels where the water level height needs to be adjusted, especially in scenarios with high requirements for water level control, and can also be used for channel gates, gates for opening and closing holes, etc.

[0039] Specifically, the soft-sealed adjustable weir gate with adjustable compression of the present embodiment comprises a movable door plate 100, a fixed door frame 200, an adjustment component 300 and a sealing component 400, wherein the movable door plate 100 can move, for example, slide, relative to the fixed door frame 200, and in actual application, the fixed door frame 200 can be fixed on concrete, for example, a concrete foundation, and the movable door plate 100 and the fixed door frame 200 can be made of stainless steel, which has a certain rigidity and water pressure resistance. The adjustment component 300 and the sealing component 400 are respectively arranged between the movable door plate 100 and the fixed door frame 200, and are respectively used to adjust the distance and sealing between the movable door plate 100 and the fixed door frame 200.

[0040] The fixed door frame 200 includes a receiving groove 210, and the edge of the movable door panel 100 extends into the receiving groove 210, and the receiving groove 210 facilitates the positioning of the movable door panel 100. The adjustment assembly 300 is connected to the edge of the movable door panel 100, and the adjustment assembly 300 includes a moving part 310, and the distance between the moving part 310 and the movable door panel 100 is adjustable. The moving part 310 contacts the side wall of the receiving groove 210, and the moving part 310 can be used to facilitate the movement of the movable door panel 100 relative to the fixed door frame 200. The sealing assembly 400 includes a sealing strip 410, and the sealing strip 410 can be made of elastic materials such as rubber. The sealing strip 410 includes a connecting portion 411 and an overhang portion 412 that are connected to each other. The connecting portion 411 is connected to the fixed door frame 200, and is separated from the movable door panel 100, that is, the connecting portion 411 is not in contact with the movable door panel 100. There is a gap between the first end of the overhang portion 412 and the side wall of the accommodating groove 210, and the second end of the overhang portion 412 is in contact with the movable door panel 100. When the movable door panel 100 is pressed from the second end of the overhang portion 412 toward the overhang portion 412, the first end of the overhang portion 412 moves and deforms toward the side wall of the accommodating groove 210, so that it can withstand a certain amount of compression, and as the pressure of the movable door panel 100 on the overhang portion 412 increases, the compression increases, and the compression can be adjusted. The adjusting component 300 is configured to press the movable door panel 100 toward the overhanging portion 412. The adjusting component 300 can change the positional relationship between the movable door panel 100 and the fixed door frame 200 by adjusting the distance between the movable portion 310 in contact with the fixed door frame 200 and the movable door panel 100, thereby pressing the movable door panel 100 toward the overhanging portion 412.

[0041] The soft-sealed adjustable weir gate with adjustable compression in this embodiment can adjust the distance between the movable part 310 and the movable door plate 100 through the adjusting component 300, thereby adjusting the gap between the movable door plate 100 and the fixed door frame 200 to achieve adjustable gap, and utilize the deformation of the suspended overhanging part 412 to make the compression amount of the movable door plate 100 on the overhanging part 412 of the sealing strip 410 change within a larger range as the gap changes. The adjustable weir gate has reliable sealing, precise water level control, small opening and closing resistance, flexible and adjustable compression amount, can adapt to various processing errors and installation errors, has a wide range of adaptability, compact structure, easy installation, simple production, and is suitable for gates that need to adjust the sealing amount, for example, it can be applied to other channel gates and gates for opening and closing holes that have low water pressure and need to adjust the compression force on site to adjust the sealing effect.

[0042] In some examples, the sealing strip 410 is a P-type rubber sealing strip, the connecting portion 411 is a straight section of the P-type rubber sealing strip, and the overhanging portion 412 is a round head of the P-type rubber sealing strip. The P-type rubber sealing strip can be an existing P-type rubber sealing strip, and the material is easily available.

[0043] In some examples, the overhang portion 412 is hollow. When the overhang portion 412 is squeezed, in addition to the overhang portion 412 moving and deforming, the overhang portion 412 can also be squeezed and deformed toward the middle hollow portion to increase the compression range.

[0044] In some examples, the overhang portion 412 protrudes toward the movable door panel 100 relative to the connecting portion 411 , so that the overhang portion 412 is in contact with the movable door panel 100 , while the connecting portion 411 is not in contact with the movable door panel 100 .

[0045] In some examples, the thickness of the overhang portion 412 is greater than that of the connecting portion 411 , and the overhang portion 412 may have higher rigidity to withstand the compression force, while the overhang portion 412 is raised relative to the connecting portion 411 to facilitate the overhang portion 412 to contact the movable door panel 100 .

[0046] In some examples, the sealing assembly 400 includes a backing plate 420 and a first fastener 430, the backing plate 420 is located on the same side of the connecting portion 411 and the overhang portion 412, the backing plate 420 is located between the connecting portion 411 and the fixed door frame 200, such as the side wall of the fixed door frame 200, and the first fastener 430 penetrates the backing plate 420 and connects the connecting portion 411 and the fixed door frame 200, such as the side wall of the fixed door frame 200. A gap between the first end of the overhang portion 412 and the side wall of the receiving groove 210 is formed on one side of the backing plate 420, and the arrangement of the backing plate 420 helps the overhang portion 412 to be suspended. The first fastener 430 can be, for example, a threaded fastener such as a screw or a bolt. The pad 420 is located between the connection part 411 and the fixed door frame 200. The pad 420 is used to separate the connection part 411 and the fixed door frame 200, thereby increasing the distance between the overhang part 412 and the edge of the fixed door frame 200, that is, the size of the gap, so that the overhang part 412 is suspended. By selecting and adjusting the thickness of the pad 420, the gap between the overhang part 412 and the fixed door frame 200 can be adjusted; by selecting and adjusting the length of the pad 420, that is, the distance that the pad 420 extends on the sealing strip 410, the length of the overhang part 412 can be adjusted. For example, the part of the sealing strip 410 that does not contact the pad 420, that is, there is a gap with the fixed door frame 200, that is, the overhang part 412. It can be seen that by selecting and adjusting the pad 420, the compression amount and compression force that the sealing strip 410 can withstand can be adjusted.

[0047] In some examples, the sealing assembly 400 further includes a first pressing plate 440, the rigidity of which is greater than the rigidity of the connecting portion 411, where the rigidity refers to the ability to resist elastic deformation when subjected to force. The first pressing plate 440 is disposed on a side of the connecting portion 411 away from the backing plate 420, the first pressing plate 440 is separated from the movable door plate 100, and the end of the first fastener 430 is located outside the first pressing plate 440. The first pressing plate 440 can be made of metal, for example. The first pressing plate 440 can prevent the connecting portion 411 from being deformed and loosened under the action of external force, and the first pressing plate 440 can be partially embedded in the connecting portion 411 to prevent the connecting portion 411 from being deformed. The first pressing plate 440 also separates the end of the first fastener 430 from the connecting portion 411, so as to prevent the end of the first fastener 430 from directly pressing against the connecting portion 411, which may cause the connection between the two to be easily damaged.

[0048] In some examples, the sealing assembly 400 also includes a second pressure plate 450, which is disposed on a side of the first pressure plate 440 away from the connecting portion 411. The second pressure plate 450 is separated from the movable door panel 100, and the end of the first fastener 430 is clamped on the second pressure plate 450. The second pressure plate 450, like the first pressure plate 440, has the function of preventing the connecting portion 411 from loosening and being damaged, thereby further improving the structural stability.

[0049] In some examples, the thickness of the second pressure plate 450 is greater than the thickness of the first pressure plate 440, and the side end of the second pressure plate 450 is in contact with the overhang 412, so that the second pressure plate 450 can support the side end of the overhang 412, avoiding the overhang 412 from deforming toward the side where the second pressure plate 450 is located, so that the deformation direction of the overhang 412 is limited, for example, basically limited to a direction perpendicular to the side wall of the accommodating groove 210, to prevent the sealing strip 410 from accidentally deforming and causing the gate door panel to open and close.

[0050] In some examples, the stiffness of the second pressure plate 450 is less than that of the first pressure plate 440. The second pressure plate 450 may be made of plastic, for example. The second pressure plate 450 uses a material with a stiffness smaller than that of the first pressure plate 440, which helps the second pressure plate 450 to fit tightly with the end of the first fastener 430 to avoid rigid contact between the two that may cause the two to become loose, and at the same time avoids contact between the second pressure plate 450 and the overhang 412 that may damage the overhang 412.

[0051] In some examples, the adjustment assembly 300 includes a first fixing plate 320, a second fixing plate 330 and a second fastener 340, the moving portion 310 is connected to the first fixing plate 320, the second fixing plate 330 is connected to the edge of the movable door panel 100, the second fastener 340 connects the first fixing plate 320 and the second fixing plate 330, and the second fastener 340 is adjustable so that the distance between the first fixing plate 320 and the second fixing plate 330 is adjustable.

[0052] In some examples, the second fastener 340 includes an adjusting bolt 341 and a nut 342, the bolt head of the adjusting bolt 341 is located on a side of the first fixing plate 320 away from the second fixing plate 330, the nut 342 is located on a side of the first fixing plate 320 close to the second fixing plate 330, the nut 342 is welded to the stud of the adjusting bolt 341, and the stud of the adjusting bolt 341 can rotatably pass through the first fixing plate 320 and threadedly engage with the second fixing plate 330. The stud of the adjusting bolt 341 and the first fixing plate 320 can be loosely engaged. With the above structure, the bolt head and the nut 342 of the adjusting bolt 341 are respectively clamped on both sides of the second fixing plate 330, so that the adjusting bolt 341 has a rotational freedom on the first fixing plate 320, but cannot move in the axial direction of the adjusting bolt 341 relative to the first fixing plate 320. The adjusting bolt 341 is rotated by twisting the bolt head of the adjusting bolt 341 , so that the stud of the adjusting bolt 341 can move in the threaded hole of the second fixing plate 330 along the axial direction of the adjusting bolt 341 .

[0053] In some examples, the adjustment assembly 300 further includes a third fastener 350, which is disposed on the second fixing plate 330 and is used to lock the second fastener 340. The third fastener 350 may be, for example, a set screw. The third fastener 350 is used to lock the second fastener 340 after determining the adjustment degree of the second fastener 340, i.e., the compression amount of the sealing assembly 400.

[0054] In some examples, when adjusting the compression amount during the installation process of the adjustable weir gate of this embodiment, a first adjustment can be performed first. According to the actual assembly size, the second fastener 340 is adjusted, for example, the bolt is turned clockwise or counterclockwise, so that the door panel can be smoothly installed in the door frame assembly, and the door panel and the sealing strip 410 are tightly sealed to prevent water leakage during water testing; after on-site installation, according to the opening and closing conditions and leakage amount of the gate after water inflow, the second fastener 340 can be adjusted for a second time to adjust the compression amount of the sealant 410 to reduce the jamming and leakage of the gate, and then by tightening the third fastener 350 on the side of the second fixing plate 330, the current compression amount can be locked to prevent the gate from loosening during frequent opening and closing.

[0055] In some examples, the moving part 310 is a roller or a slider. The roller can make the weir gate open and close conveniently, and the slider can be used in scenes with high water pressure, such as a gate for opening and closing a pipe mouth. The receiving groove 210 can be provided with a slide rail that cooperates with the slider. The structure and form of the moving part 310 can be selected according to actual needs, and the roller and the slider can be existing rollers and sliders.

[0056] In some examples, the adjustment assembly 300 further includes a fixing frame 360 ​​, which is disposed on the first fixing plate 320 , and the moving part 310 is connected to the fixing frame 360 ​​to facilitate the positioning and installation of the moving part 310 .

[0057] In some examples, second fasteners 340 are respectively disposed on both sides of the movable portion 310 so that the force on the adjustment assembly 300 is more uniform and the movable portion 310 can remain flat.

[0058] In some examples, a reinforcing channel steel is disposed at the edge of the movable door panel 100 , and the second fixing plate 330 is connected to the reinforcing channel steel, for example, by being embedded and welded into the reinforcing channel steel, so as to improve the connection rigidity.

[0059] In some examples, the side wall of the receiving groove 210 includes a first side wall 211 and a second side wall 212; the adjusting assembly 300 is arranged between the edge of the movable door plate 100 and the first side wall 211, and the moving part 310 contacts the first side wall 211 of the receiving groove 210; the sealing assembly 400 is arranged between the edge of the movable door plate 100 and the second side wall 212, and there is a gap between the first end of the overhanging part 412 and the second side wall 212 of the receiving groove 210, and the second end of the overhanging part 412 contacts the surface of the movable door plate 100 away from the adjusting assembly 300. That is, the adjusting assembly 300 and the sealing assembly 400 can be arranged on different sides of the movable door plate 100, and the layout is more reasonable, which is convenient for adjusting the adjusting assembly 300. The first side wall 211 and the second side wall 212 can be flush or uneven. In this embodiment, the second side wall 212 can be longer than the first side wall 211, providing a larger area for the connection part 411 of the sealing assembly 400 to cooperate with the first side wall 211.

[0060] In some examples, the projection of the adjustment assembly 300 on the edge of the movable door panel 100 at least partially overlaps with the projection of the sealing assembly 400 on the edge of the movable door panel 100, so that the adjustment assembly 300, the movable door panel 100 and the sealing assembly 400 are subjected to more uniform force, avoiding twisting and bending of the components.

[0061] In some examples, the fixed door frame 200 includes a groove plate 220 and a support plate 230, the groove plate 220 surrounds the receiving groove 210, the support plate 230 is located outside the receiving groove 210 and connected to the groove plate 220, the projection of the support plate 230 on the edge of the movable door plate 100 falls within the projection of the connecting portion 411 on the edge of the movable door plate 100, and the support plate 230 can provide a supporting force to prevent the side wall of the receiving groove 210 from deforming under pressure. The groove plate 220 and the support plate 230 can be integrated or assembled from multiple steel plates.

[0062] In some examples, the adjustment assembly 300 is disposed at the left and right ends of the movable door panel 100, and the moving part 310 is disposed at the left and right ends of the movable door panel 100 to facilitate the upward and downward movement of the movable door panel 100. The receiving groove 210 is disposed at the left and right ends of the fixed door frame 200, and is used to limit and seal the movable door panel 100. The fixed door frame 200 is also provided with a frame at the upper and lower ends, and the sealing assembly 400 is disposed in the receiving groove 210 and on the frame. The sealing assembly 400 can be surrounded in a square shape on the fixed door frame 200. The sealing assembly 400 disposed in the receiving groove 210 adjusts the compression amount through the adjusting assembly 300 to achieve sealing between the movable door panel 100 and the fixed door frame 200 at the left and right ends, and the sealing assembly 400 disposed on the frame achieves sealing at the upper and lower ends through the contact between the sealing assembly 400 and the frame. When the adjusting assembly 300 adjusts the compression amount of the sealing assembly 400 at the left and right ends, since the displacement of the left and right ends of the movable door panel 100 drives the displacement of the entire movable door panel 100, the adjusting assembly 300 also adjusts the compression amount of the sealing assembly 400 disposed on the frame. For example, the adjusting assembly 300 may include at least 4 groups of adjusting assemblies 300, wherein the 4 groups of adjusting assemblies 300 are respectively disposed at the four corners of the movable door panel 100, and by adjusting the distance between the 4 groups of adjusting assemblies 300, the compression amount of the sealing assembly 400 by the four edges of the movable door panel 100 on the upper, lower, left and right sides can be adjusted.

[0063] The length of the overhanging portion 412 disposed in the receiving groove 210 is different from the length of the overhanging portion 412 disposed on the frame. For example, the same type of sealing strip 410 can be disposed around the fixed door frame 200, and the different lengths of the overhanging portion 412 can be adjusted by selecting and adjusting the length of the backing plate 420, that is, the different distances that the backing plate 420 extends on the sealing strip 410. Alternatively, the stiffness of the sealing strip 410 disposed in the receiving groove 210 is different from the stiffness of the sealing strip 410 disposed on the frame. For example, different types of sealing strips 410 can be disposed around the fixed door frame 200 to obtain different stiffnesses of the sealing strip 410. Through the above arrangement, the compression forces that the movable door panel 100 and the fixed door frame 200 can withstand at the left and right ends and the upper and lower ends can be different. For example, in some examples, the width of the adjustable weir gate is larger than the height, and the stiffness of the left and right ends of the movable door panel 100 is larger than the stiffness of the upper and lower ends of the movable door panel 100, resulting in different pressures per unit length on the sealing strips 410 on the four edges, and different compression requirements on the four edges. At this time, an overhang 412 with a larger length than the left and right ends can be used at the upper and lower ends, so that the unit compression force of the sealing strips 410 on the four edges is different to adapt to the different stiffness of the door panel edges, so that the sealing strips 410 can be effectively sealed at each edge to prevent water leakage, and match the force conditions when opening and closing each edge, thereby reducing the opening and closing resistance of each edge.

[0064] Finally, it should be emphasized that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
