Description

Technical Field

[0001] The invention relates to the technical field of mechanical design, in particular to a frame component with sealing function and an automatic gate valve device. Background Art

[0002] In modern agricultural irrigation systems, irrigation channels for high-standard farmland are generally treated with concrete hardening and equipped with gate valves for precise control of water flow. For example, Chinese patent CN219490887U discloses an automated control gate valve device specially designed for channel irrigation and drainage. The device mainly consists of a base plate, a drive mechanism, and a plate gate, wherein the drive mechanism is mounted on the base plate, and the base plate is provided with a water outlet. The plate gate structure consists of a guide groove and a gate plate, the guide groove is fixed to the base plate, and the gate plate is slidably connected along the guide groove direction to ensure its smooth movement. The drive mechanism acts on the gate plate through a mechanical connection to realize the opening or closing operation of the gate plate. In addition, in order to ensure the sealing performance, a sealing structure is also specially provided on the base plate, including a sealing ring around the water outlet, a positioning protrusion located in the guide groove, and a pressing component mounted on the gate plate. When the gate plate is closed, the pressing component is aligned with the positioning protrusion to form a close contact, thereby effectively preventing water leakage.

[0003] However, in actual application, the sealing components of the gate valves deteriorate in sealing performance after long-term operation due to the alignment of the press-fit parts with the positioning protrusions and continuous wear and tear after long-term use, resulting in water leakage, which affects the efficiency and accuracy of irrigation management. This not only weakens the effective use of water resources, but also increases the maintenance cost of the equipment. Summary of the invention

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] Embodiment 1

[0033] Based on the problems mentioned in the background technology, a gate valve and an automatic control gate valve for channel irrigation and drainage are disclosed using Chinese patent publication number CN219490887U. It is actually found that when the gate plate 7 slides up and down in the base plate to release and block water, water often flows from the contact edge of the gate plate 7 with the base plate during the water blocking stage, presenting a small but continuous overflow phenomenon.

[0034] Based on this, this embodiment designs a corresponding solution for the water leakage phenomenon, and specifically provides a frame 1 component with a sealing function for use in combination with the above-mentioned gate plate 7. Figures 2 to 3As shown, it includes a frame 1, a guide groove 2, a plurality of first sealing strips 3 and a second sealing strip 4, wherein the two guide grooves 2 are respectively arranged on the two side surfaces installed in the frame 1, and are used for sliding with the two side edges of the gate plate 7. The frame 1 is installed in the vertical direction, and its internal shape is adapted to the shape of the gate plate 7. The frame 1 is a rectangular frame structure, and its internal space is set as a rectangular space. At the same time, the first sealing strips 3 are respectively installed on the two inner sides of the guide groove 2. Compared with the traditional track structure, the first sealing strip 3 is combined with the guide groove 2 to form a flexible slide track groove. The first sealing strip 3 is an elastic member, that is, in actual use, the first sealing strip 3 is actually pressed against the edge surface of the side of the gate plate 7 and generates a certain elastic pressure. The bottom surface of the frame 1 is provided with a second sealing strip 4, and the second sealing strip 4 is also an elastic member. Then, when the gate plate 7 is pressed on the second sealing strip 4, the second sealing strip 4 is squeezed to generate elastic deformation, and an effective seal can be formed at this time.

[0035] In this embodiment, the cross-section of the first sealing strip 3 is a "6"-shaped hollow structure, in which the hollow structure is a cylindrical hollow. The design here can adapt to the thickness parameters of the gate plate 7, and at the same time, the surface of the first sealing strip 3 is smoothed to reduce the sliding friction of the gate plate 7.

[0036] In this embodiment, the cross section of the second sealing strip 4 is in a convex shape, the convex portion of the shape is an inclined surface or a semicircular arc surface with an inclined angle, and the convex portion is a hollow structure.

[0037] Based on the design of the second sealing strip 4, the two corners inside the frame 1 are chamfered so that the two ends of the second sealing strip 4 installed on the bottom surface of the frame 1 are bent in a preset shape. Based on the actual implementation, the gate 7 is designed with corresponding chamfers and the two corners inside the frame 1 are planned with corresponding chamfers. For example, the corners are raised and an arc-shaped surface is laid, and the two ends of the second sealing strip 4 are laid on the arc-shaped surface, and the bottom of the first sealing strip 3 is connected to the two ends of the second sealing strip 4. Then, in actual use, the two bottom corners of the gate are also designed with corresponding rounded corners to achieve tight closure.

[0038] In this embodiment, the guide groove 2 includes two first pressure strips 5, the two first pressure strips 5 are set at a distance based on the thickness of the gate plate 7, and are installed parallel to the side surface inside the frame 1. The shape of the first pressure strips 5 is a 90° angle iron shape.

[0039] In this embodiment, the second pressure strip 6 is installed on the bottom surface of the frame 1 to fix the second sealing strip 4 .

[0040] Embodiment 2

[0041] Based on the first embodiment, this embodiment proposes an automatic gate valve device, such as Figure 1As shown, the frame assembly with sealing function mentioned in the first embodiment also includes a gate plate 7, a motor group 8, and a controller 9, wherein the gate plate 7 is arranged to slide up and down in the frame 1, the end of the gate plate 7 is located in the first slide groove, and the thickness of the gate plate 7 is greater than the spacing value between the two first sealing strips 3, and less than the spacing value between the two first pressure strips 5 located on the same side, so that the first sealing strip 3 seals the gap between the gate plate 7 and the frame 1, and when the two ends of the gate plate 7 slide, the first sealing strip 3 is squeezed at the same time, so that the two first sealing strips 3 on both sides produce elastic deformation, thereby achieving sealing. At the same time, since the first sealing strips 3 on both sides produce elastic deformation, when the gate plate 7 may be disturbed by the particles in the external environment, resulting in its non-linear movement, the flexible slide groove formed by the first sealing strip 3 allows the gate plate 7 to have more space assembly parameters. The motor group 8 is installed at the top of the frame 1, and its output end has a lifting function. The output end of the motor group 8 is connected to the top of the gate plate 7, and the controller 9 is electrically connected to the motor group 8.

[0042] When the motor group 8 controls the gate plate 7 to descend, the gate plate 7 begins to be squeezed from the upper surface of the second sealing strip 4. At this time, the hollow structure of the second sealing strip 4 shrinks, and the second sealing strip 4 fits tightly against the bottom surface of the gate plate 7. In the present embodiment, the cross-section of the second sealing strip 4 is a convex shape, and the raised portion of the shape is set as a slope with an inclined angle. In actual use, the formation area of ​​the second sealing strip 4 gradually increases, and the degree of deformation decreases. The deformation at its raised portion is the most obvious, so its slope gradually increases from local surface contact or line contact to surface contact, and finally the entire slope is squeezed at the bottom of the gate plate 7.

[0043] The raised part can also be set as a semicircular arc surface, which also has the above-mentioned effect, and its effect is similar to that of the inclined surface with an inclined angle. However, compared with the above-mentioned inclined surface solution, the semicircular arc surface structure is relatively uniform in force, and after countless uses, its service life is greater than that of the above-mentioned inclined surface design solution.

[0044] Compared with the traditional direct pressing for sealing, the advantage of this solution is that the sealing method is a step-by-step sealing process of increasing the contact surface, and the hollow design not only serves as a condition for elastic deformation, but also can store some air to maintain the structural recovery ability of the second sealing strip 4.

[0045] For another example, there are particles temporarily on the surface of the second sealing strip 4, and the particles exist in a certain area. However, through the above-mentioned connection and pressing scheme of gradually increasing the contact surface, the surrounding area where the area is located can still be tightly squeezed on the bottom of the gate plate 7, and sealing is always achieved.

[0046] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
