[0039] Specifically, the adjustable soft sealing adjusting weir gate of compression quantity of the embodiment includes movable door plate 100, fixed door frame 200, adjusting assembly 300 and sealing assembly 400, wherein movable door plate 100 can be moved, for example, sliding relative to fixed door frame 200, in actual application, fixed door frame 200 can be fixed on concrete, for example, concrete foundation, movable door plate 100 and fixed door frame 200 can be made of stainless steel, have certain rigidity, water pressure resistance.Adjusting assembly 300 and sealing assembly 400 are respectively arranged between movable door plate 100 and fixed door frame 200, and are respectively used for adjusting the distance between movable door plate 100 and fixed door frame 200 and the sealing property.

[0040] The fixed door frame 200 comprises a receiving groove 210, the edge of the movable door plate 100 extends into the receiving groove 210, and the receiving groove 210 facilitates positioning of the movable door plate 100. The adjusting assembly 300 is connected to the edge of the movable door plate 100, and the adjusting assembly 300 comprises a moving part 310, the distance between the moving part 310 and the movable door plate 100 is adjustable, the moving part 310 is in contact with the side wall of the receiving groove 210, and the moving part 310 can be used to facilitate movement of the movable door plate 100 relative to the fixed door frame 200. The sealing assembly 400 comprises a sealing rubber strip 410, which can be made of elastic materials such as rubber. The sealing rubber strip 410 comprises a connecting part 411 and a cantilever part 412 connected to each other, the connecting part 411 is connected to the fixed door frame 200, the connecting part 411 is separated from the movable door plate 100, that is, the connecting part 411 is not in contact with the movable door plate 100, and a gap exists between the first end of the cantilever part 412 and the side wall of the receiving groove 210, and the second end of the cantilever part 412 is in contact with the movable door plate 100. When the movable door plate 100 is pressed towards the cantilever part 412 from the second end of the cantilever part 412, the first end of the cantilever part 412 moves and deforms towards the side wall of the receiving groove 210, so that a certain compression amount can be borne, and as the pressure of the movable door plate 100 on the cantilever part 412 increases, the compression amount increases, and the compression amount can be adjusted. The adjusting assembly 300 is configured such that the movable door plate 100 is pressed towards the cantilever part 412, and the adjusting assembly 300 can adjust the distance between the moving part 310 in contact with the fixed door frame 200 and the movable door plate 100, so that the positional relationship between the movable door plate 100 and the fixed door frame 200 changes, and then the movable door plate 100 is pressed towards the cantilever part 412.

[0041] The compression-adjustable soft sealing adjusting weir gate of the embodiment can adjust the distance between the moving part 310 and the movable door plate 100 through the adjusting assembly 300, so as to adjust the gap between the movable door plate 100 and the fixed door frame 200, realize adjustable gap, and utilize the deformation of the cantilever part 412 in suspension to enable the compression amount of the movable door plate 100 on the cantilever part 412 of the sealing rubber strip 410 to change in a large range following the change of the gap. The adjusting weir gate is reliable in sealing, accurate in water level height control, small in opening and closing resistance, flexible in compression amount adjustment, can adapt to various processing errors and installation errors, has a wide adaptation range, is compact in structure, convenient to install, simple to manufacture, and suitable for gates that need to adjust the sealing amount, for example, can be applied to other channel gates that have small water pressure and need to adjust the sealing effect by adjusting the compression force on site, hole opening and closing gates, and the like.

[0042] In some examples, the sealing rubber strip 410 is a P-shaped rubber sealing strip, the connecting part 411 is a straight section of the P-shaped rubber sealing strip, and the cantilever part 412 is a circular head of the P-shaped rubber sealing strip. The P-shaped rubber sealing strip can be an existing P-shaped rubber sealing strip, and the material is easy to obtain.

[0043] In some examples, the overhang 412 is hollow, and when the overhang 412 is pressed, the overhang 412 can be pressed and deformed towards the middle hollow part in addition to the movement and deformation of the overhang 412, thereby increasing the compression range.

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

[0045] In some examples, the thickness of the overhang 412 is greater than the thickness of the connecting part 411, so that the overhang 412 has higher rigidity to withstand the compression force, while the overhang 412 protrudes relative to the connecting part 411 to facilitate the overhang 412 to be in contact with 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 part 411 and the overhang 412, the backing plate 420 is located between the connecting part 411 and the fixed door frame 200, for example, the side wall of the fixed door frame 200, and the first fastener 430 penetrates the backing plate 420 and connects the connecting part 411 and the fixed door frame 200, for example, the side wall of the fixed door frame 200. The gap between the first end of the overhang 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 412 to be suspended. The first fastener 430 can be a threaded fastener such as a screw, a bolt, etc. The backing plate 420 is located between the connecting part 411 and the fixed door frame 200, and the backing plate 420 is used to separate the connecting part 411 and the fixed door frame 200, thereby increasing the distance, i.e. the size of the gap, between the overhang 412 and the edge of the fixed door frame 200, so that the overhang 412 is suspended. By selecting and adjusting the thickness of the backing plate 420, the gap between the overhang 412 and the fixed door frame 200 can be adjusted; by selecting and adjusting the length of the backing plate 420, i.e. the distance that the backing plate 420 extends on the sealing strip 410, the length of the overhang 412, for example, the part of the sealing strip 410 that is not in contact with the backing plate 420, i.e. has a gap with the fixed door frame 200, i.e. constitutes the overhang 412, can be adjusted. It can be seen that by selecting and adjusting the backing plate 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 comprises a first pressing plate 440, the first pressing plate 440 having a rigidity greater than that of the connecting portion 411, where the rigidity refers to the ability to resist elastic deformation under force. The first pressing plate 440 is disposed on the side of the connecting portion 411 away from the pad 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 deforming and loosening under external force, and the first pressing plate 440 can be partially embedded in the connecting portion 411 to prevent the connecting portion 411 from deforming. The first pressing plate 440 also separates the end of the first fastener 430 from the connecting portion 411, avoiding the end of the first fastener 430 directly pressing against the connecting portion 411 and causing the connection between the two to be easily damaged.

[0048] In some examples, the sealing assembly 400 further comprises a second pressing plate 450, the second pressing plate 450 being disposed on the side of the first pressing plate 440 away from the connecting portion 411, the second pressing plate 450 being separated from the movable door plate 100, and the end of the first fastener 430 being clamped on the second pressing plate 450. The second pressing plate 450 has the same effect as the first pressing plate 440 in preventing the connecting portion 411 from loosening and being damaged, further improving the structural stability.

[0049] In some examples, the second pressing plate 450 has a thickness greater than that of the first pressing plate 440, and the side end of the second pressing plate 450 is in contact with the overhanging portion 412, so that the second pressing plate 450 can push against the side end of the overhanging portion 412, avoiding the overhanging portion 412 from deforming to the side where the second pressing plate 450 is located, limiting the deformation direction of the overhanging portion 412, for example, to a direction perpendicular to the side wall of the accommodating groove 210, preventing the sealing rubber strip 410 from deforming unexpectedly and causing the gate door plate to malfunction.

[0050] In some examples, the second pressing plate 450 has a rigidity less than that of the first pressing plate 440, and the second pressing plate 450 can be made of plastic, for example. The second pressing plate 450 is made of a material having a rigidity less than that of the first pressing plate 440, which helps the second pressing plate 450 to tightly fit with the end of the first fastener 430, avoiding the two to be easily loosened due to rigid contact, and avoiding the second pressing plate 450 to contact with the overhanging portion 412 and cause the overhanging portion 412 to be damaged.

[0051] In some examples, the adjusting assembly 300 comprises a first fixed plate 320, a second fixed plate 330, and a second fastener 340, the moving portion 310 being connected to the first fixed plate 320, the second fixed plate 330 being connected to the edge of the movable door plate 100, and the second fastener 340 connecting the first fixed plate 320 and the second fixed plate 330. The second fastener 340 is adjustable so that the distance between the first fixed plate 320 and the second fixed 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 the side of the first fixed plate 320 away from the second fixed plate 330, the nut 342 is located on the side of the first fixed plate 320 close to the second fixed plate 330, the nut 342 is welded with the threaded shank of the adjusting bolt 341, and the threaded shank of the adjusting bolt 341 is rotatably penetrated through the first fixed plate 320 and threadedly matched with the second fixed plate 330. There can be a loose fit between the threaded shank of the adjusting bolt 341 and the first fixed plate 320. With the above structure, the bolt head of the adjusting bolt 341 and the nut 342 are clamped on the two sides of the second fixed plate 330 respectively, so that the adjusting bolt 341 has a rotational freedom on the first fixed plate 320, but cannot move axially relative to the first fixed plate 320. By rotating the bolt head of the adjusting bolt 341, the threaded shank of the adjusting bolt 341 can be moved axially in the threaded hole of the second fixed plate 330.

[0053] In some examples, the adjusting assembly 300 further includes a third fastener 350 arranged on the second fixed plate 330, and the third fastener 350 is used to lock the second fastener 340. The third fastener 350 can be a locking screw, for example. The third fastener 350 is used to lock the second fastener 340 after the compression amount of the sealing assembly 400 is determined.

[0054] In some examples, when the adjusting weir gate of the present embodiment adjusts the compression amount during installation, the first adjustment can be performed first, and the second fastener 340 is adjusted, for example, clockwise or counterclockwise, according to the actual assembly size, so that the door plate can be smoothly installed in the door frame set and the sealing between the door plate and the sealing strip 410 is ensured to be tight, and there is no water leakage during water test; after field installation, according to the opening and closing state of the gate and the leakage amount after water inflow, the second fastener 340 can be adjusted again to adjust the compression amount of the sealing strip 410, so as to reduce the jamming and leakage of the gate, and then the third fastener 350 on the side of the second fixed plate 330 is tightened to lock the current compression amount, so as to prevent the compression amount from being loose during the frequent opening and closing of the gate in the future.

[0055] In some examples, the moving part 310 is a roller or a sliding block. The roller can make the weir gate open and close conveniently, and the sliding block can be suitable for scenes with high water pressure, such as gate for pipe opening and closing. The accommodating groove 210 can be provided with a sliding rail matched with the sliding block. The structure and form of the moving part 310 can be selected according to actual needs, and the roller and the sliding block can be existing rollers and sliding blocks.

[0056] In some examples, the adjusting assembly 300 further comprises a fixing frame 360, which is arranged on the first fixing plate 320, and the moving part 310 is connected to the fixing frame 360, facilitating the positioning and installation of the moving part 310.

[0057] In some examples, the second fasteners 340 are arranged on both sides of the moving part 310, so that the adjusting assembly 300 is more uniform in stress, and the moving part 310 can remain flat.

[0058] In some examples, the edge of the movable door plate 100 is provided with a reinforcing channel steel, and the second fixing plate 330 is connected to the reinforcing channel steel, for example, inlaid and welded into the reinforcing channel steel, to improve the connection stiffness.

[0059] In some examples, the side wall of the accommodating groove 210 comprises 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, the moving part 310 is in contact with the first side wall 211 of the accommodating 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 accommodating groove 210, and the second end of the overhanging part 412 is in contact with 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, facilitating the adjustment of the adjusting assembly 300. The first side wall 211 and the second side wall 212 can be flush or not flush, and in this embodiment, the second side wall 212 can be longer than the first side wall 211, providing a larger area for the connecting part 411 of the sealing assembly 400 to cooperate with the first side wall 211.

[0060] In some examples, the projection of the adjusting assembly 300 on the edge of the movable door plate 100 at least partially overlaps the projection of the sealing assembly 400 on the edge of the movable door plate 100, so that the adjusting assembly 300, the movable door plate 100 and the sealing assembly 400 are more uniform in stress, avoiding distortion and bending of each component.

[0061] In some examples, the fixed door frame 200 comprises a groove plate 220 and a support plate 230, the groove plate 220 surrounds the accommodating groove 210, and the support plate 230 is located outside the accommodating 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 part 411 on the edge of the movable door plate 100, and the support plate 230 can provide a supporting force to avoid deformation of the side wall of the accommodating groove 210 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 adjusting assembly 300 is arranged at the left and right ends of the movable door panel 100, and the moving part 310 is arranged at the left and right ends of the movable door panel 100 to facilitate the up and down movement of the movable door panel 100. The accommodating groove 210 is arranged at the left and right ends of the fixed door frame 200 to limit and seal the movable door panel 100. The fixed door frame 200 is further provided with a frame at the upper and lower ends, and the sealing assembly 400 is arranged in the accommodating groove 210 and on the frame. The sealing assembly 400 can form a mouth-shaped pattern on the fixed door frame 200. The sealing assembly 400 arranged in the accommodating groove 210 adjusts the compression amount by the adjusting assembly 300 to realize the sealing between the left and right ends of the movable door panel 100 and the fixed door frame 200, and the sealing assembly 400 arranged on the frame realizes the sealing of the upper and lower ends by 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, the displacement of the left and right ends of the movable door panel 100 drives the displacement of the whole movable door panel 100, and the adjusting assembly 300 also adjusts the compression amount of the sealing assembly 400 arranged on the frame. For example, the adjusting assembly 300 can include at least four groups of adjusting assemblies 300, and the four groups of adjusting assemblies 300 are arranged at the four corners of the movable door panel 100. By adjusting the distance between the four groups of adjusting assemblies 300, the compression amount of the sealing assembly 400 by the four edges of the movable door panel 100 can be adjusted.

[0063] In some examples, the length of the overhanging part 412 arranged in the accommodating groove 210 is different from the length of the overhanging part 412 arranged on the frame. For example, the same type of sealing strip 410 can be arranged around the fixed door frame 200, and the different distances of the extension of the gasket 420 on the sealing strip 410 can be selected and adjusted to adjust the different lengths of the overhanging part 412. Alternatively, the rigidity of the sealing strip 410 arranged in the accommodating groove 210 is different from the rigidity of the sealing strip 410 arranged on the frame. For example, different types of sealing strips 410 can be arranged around the fixed door frame 200 to obtain different rigidity of the sealing strip 410. Through the above arrangement, the compression force that can be borne between the movable door panel 100 and the fixed door frame 200 at the left and right ends and the upper and lower ends can be different. For example, in some examples, the width of the weir door is greater than the height, and the rigidity of the left and right ends of the movable door panel 100 is greater than the rigidity of the upper and lower ends of the movable door panel 100, resulting in that the unit length pressure of the sealing strip 410 on the four edges is different, and the demand for compression amount of the four edges is also different. At this time, the length of the overhanging part 412 at the upper and lower ends can be greater than that at the left and right ends, so that the unit compression force of the sealing strip 410 of the four edges is different, to adapt to the different rigidity of the door panel edges, so that the sealing strip 410 can effectively seal at each edge to prevent water leakage, and match the stress condition when each edge is opened and closed, thereby reducing the opening and closing resistance of each edge.

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