[0031] The utility model will be described further in conjunction with the drawings.
[0032] Example one
[0033] Based on the problems mentioned in the background art, a gate valve and automatic control gate valve for channel irrigation and drainage are disclosed in Chinese patent publication No. CN219490887U. It is found that when the gate board 7 slides up and down in the base plate to release water and block water, there is often a small but continuous overflow of water from the contact edge of the gate board 7 base plate during the water blocking stage.
[0034] Based on this, the embodiment designs a corresponding scheme for the water leakage phenomenon, specifically sets up a frame 1 component with sealing function for combined use with the above-mentioned gate board 7. For example, Figures 2 to 3As shown, it comprises a frame 1, guide grooves 2, multiple sets of first sealing strips 3 and second sealing strips 4, wherein two guide grooves 2 are respectively arranged on two side surfaces installed in the frame 1 for combined sliding use with two side edges of the gate plate 7, the frame 1 is installed in a vertical direction, the internal shape thereof is adapted to the shape of the gate plate 7, the frame 1 is a rectangular frame structure, the internal space thereof is arranged as a rectangular space, meanwhile, the first sealing strips 3 are respectively installed on the two inner side surfaces of the guide grooves 2, compared with the traditional track structure, the first sealing strips 3 are combined with the guide grooves 2 to form a flexible sliding track groove, the first sealing strips 3 are elastic members, that is, in actual use, the first sealing strips 3 are actually pressed against the edge surface of the side surface of the gate plate 7 and generate a certain elastic pressure. The bottom surface in the frame 1 is provided with the second sealing strips 4, the second sealing strips 4 are also elastic members, then when the gate plate 7 is pressed on the second sealing strips 4 to extrude the second sealing strips 4 and generate elastic deformation, effective sealing can be formed at this time.
[0035] In the embodiment, the cross section of the first sealing strip 3 is a hollow structure in the shape of “6”, the hollow structure is a cylindrical hollow structure, in this scheme, the thickness parameter of the gate plate 7 can be self-adapted, meanwhile, the surface of the first sealing strip 3 is smoothed to reduce the sliding friction of the gate plate 7.
[0036] In the embodiment, the cross section of the second sealing strip 4 is in the shape of a convex character, the convex part of the shape is a bevel with an inclined angle or a semicircular arc surface, and the convex part is a hollow structure.
[0037] Based on the design of the second sealing strip 4, the two corners in the frame 1 are chamfered to make the two ends of the second sealing strip 4 installed on the bottom surface of the frame 1 be bent in a preset shape. Based on the actual implementation, the gate plate 7 is designed with corresponding chamfers and the two corners in the frame 1 are designed with corresponding chamfer planning. For example, the corners are raised and an arc surface is laid, the two ends of the second sealing strip 4 are laid to the arc surface, and the bottom of the first sealing strip 3 is connected with the two ends of the second sealing strip 4. Then in actual use, the two bottom corners of the gate plate are also designed with corresponding round corners to realize close closing.
[0038] In the embodiment, the guide groove 2 comprises two first pressing strips 5, the two first pressing strips 5 are arranged at a distance based on the thickness of the gate plate 7 and are installed in parallel on the side surface in the frame 1, the shape of the first pressing strip 5 is an angle iron shape with an angle of 90°.
[0039] In the embodiment, the second pressing strip 6 is installed on the bottom surface in the frame 1 for fixing the second sealing strip 4.
[0040] Embodiment two
[0041] On the basis of embodiment one, the embodiment proposes an automatic gate valve device, like Figure 1As shown, in addition to the frame assembly with sealing function mentioned in Embodiment One, the embodiment also includes the shutter 7, the motor set 8, and the controller 9. The shutter 7 is arranged to slide up and down within the frame 1, with the ends of the shutter 7 located in the first sliding groove. The thickness of the shutter 7 is greater than the spacing between the two first sealing strips 3 and less than the spacing between the two first pressing strips 5 on the same side, so that the first sealing strips 3 seal the gap between the shutter 7 and the frame 1. When the two ends of the shutter 7 slide, the first sealing strips 3 on both sides are elastically deformed, thereby achieving sealing. At the same time, due to the elastic deformation of the first sealing strips 3 on both sides, when the shutter 7 is disturbed by external environmental particles, causing its movement to be non-linear, the flexible sliding track groove formed by the first sealing strips 3 allows the shutter 7 to have more space for assembly parameters. The motor set 8 is installed at the top of the inside of the frame 1, with the output end having a lifting function. The output end of the motor set 8 is connected to the top of the shutter 7, and the controller 9 is electrically connected to the motor set 8.
[0042] When the motor set 8 controls the shutter 7 to descend, the shutter 7 starts to press from the upper surface of the second sealing strip 4. At this time, the hollow structure of the second sealing strip 4 contracts, and the second sealing strip 4 tightly fits the bottom surface of the shutter 7. In this embodiment, the cross section of the second sealing strip 4 is in the shape of a convex character. The convex part of the shape is designed as an inclined surface with an inclined angle. In actual use, the area formed by the second sealing strip 4 gradually increases, and the degree of deformation decreases. The deformation of the convex part is most obvious, so the inclined surface gradually increases the surface contact from partial surface contact or line contact, and finally realizes the entire inclined surface pressing on the bottom of the shutter 7.
[0043] The convex part can also be designed as a semicircular surface, which also has the above-mentioned effect, and its effect is similar to the inclined surface with an inclined angle. However, the structure of the semicircular surface is relatively uniform in stress compared to the above-mentioned inclined surface design. After being used countless times, its service life is greater than that of the above-mentioned inclined surface design.
[0044] Compared with the traditional direct pressing sealing, the advantage of this scheme is that the sealing method is a step-by-step increase in the contact surface sealing process. The hollow design not only serves as a condition for elastic deformation but also can store part of the air to maintain the structure recovery ability of the second sealing strip 4.
[0045] For example, there are particles on the surface of the second sealing strip 4, and the particles exist in a certain area. However, through the above-mentioned step-by-step increase in the contact surface pressing scheme, the surrounding area of the area can still be tightly pressed on the bottom of the shutter 7, and sealing is always achieved.
[0046] The above are only preferred embodiments of the present application, and it should be pointed out that: for ordinary skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered within the scope of the present application.
