Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to a water-stopping structure of a winch-type steel gate of a hydraulic structure. Background Art

[0002] At present, steel gates are a common device used for water discharge, flood control and water retaining in hydraulic structures. Common structures include gate slots and gates that match the gate slots; the gates and gate slots are both made of steel structures, with rollers on both sides of the gates, which can slide along the gate slots, and the process of water storage and release is achieved by lifting the gates. Common structures also include the gate blade panels, beam systems, horizontal and vertical connection systems or partitions, hoists, water stops, guide wheels, and peripheral embedded parts, tracks, etc. The most common forms are plane and arc gates.

[0003] During the water storage stage, in order to improve the sealing of the gate structure and prevent water leakage, it is generally chosen to set a waterstop on the mating surface of the gate and the gate slot on the water inlet side, usually on the side and bottom of the gate, where the waterstop is mostly a P-type rubber waterstop; for the waterstop set on the water inlet side of the gate, due to the poor wear resistance of rubber, the waterstop and the gate slot are repeatedly rubbed when the gate is raised and lowered, resulting in continuous damage to the waterstop; in addition, for the waterstop set on the bottom of the gate, it is eroded by the extremely fast water flow during water discharge, which will also cause continuous damage to the waterstop, thereby greatly reducing the durability and sealing of the waterstop for the gate structure, and also causing it to become the main maintenance object in the gate structure. In this way, it also greatly affects the use efficiency of the sluice and increases the maintenance cost of the gate. Therefore, designing a new type of waterstop device with simple structure, low cost, convenient maintenance, strong practicality and good durability is an urgent problem to be solved by people in this field. Summary of the invention

[0004] In order to solve the problem of low service life of the waterstop strip in the reservoir gate structure, the present invention proposes a gate waterstop structure, which ensures the sealing of the gate structure while increasing the service life of the waterstop strip and reducing the maintenance cost of the gate structure.

[0005] The technical solution proposed in the present invention is: a gate water-stop structure, comprising a gate and a gate groove that match each other; a water-stop strip is arranged on the edge of the gate outlet side; at the same time, a guide wheel is also arranged on the gate outlet side, and the turning radius of the guide wheel is greater than the thickness of the water-stop strip; a guide wheel groove is arranged in the gate groove, and the guide wheel corresponds to the guide wheel groove.

[0006] In use, the present application also achieves the process of water storage and waterproofing by lifting and lowering the gate, wherein the lifting method of the gate can be selected by a method familiar to those skilled in the art, such as the "A special gate lifting device for water conservancy and hydropower" disclosed in Chinese patent document CN108589666A. Since it does not belong to the protection scope of the present application, it is not described in detail here; in the present application, the waterstop is arranged on the edge of the water outlet side of the gate, and it is arranged on the side of the gate rather than at the bottom of the gate, so as to prevent the impact of the water flow on the waterstop when the gate is opened, thereby improving the life of the waterstop; by arranging a guide wheel on the water outlet side of the gate, the guide wheel is rotatably arranged on the gate through a bearing, for example, a countersunk hole can be pre-arranged on the water outlet side of the gate, and its cross-section can be square or arc-shaped, and then the guide wheel is passed through the guide wheel shaft, and the guide wheel rotates around the guide wheel shaft, and then the two ends of the guide wheel shaft are fixed It is fixed in the countersunk hole, with one part of the guide wheel located in the countersunk hole and the other part protruding from the water outlet side of the gate; in the present application, the turning radius of the guide wheel is greater than the thickness of the waterstop, that is, the height of the guide wheel protruding from the water outlet side of the gate is greater than the thickness of the waterstop. When the gate rises or falls in the gate groove, the guide wheel also slides down along the gate groove, but at this time the waterstop is not in contact with the gate groove, thus avoiding the wear of the waterstop during the up and down lifting of the gate and increasing the life of the waterstop; in the present application, a guide wheel groove is provided in the gate groove, and the guide wheel corresponds to the guide wheel groove, that is, a guide wheel groove is provided on the side where the guide wheel slides on the inner side of the gate groove, and the guide wheel groove is recessed in the inner side of the gate groove, which can accommodate the part of the guide wheel protruding from the gate side. In actual operation, when the guide wheel slides to the guide wheel groove on the inner side of the gate groove, the guide wheel cooperates with the guide wheel groove. At this time, the gate is fitted with the gate groove, and the pressure of the water on the water inlet side of the gate is used to make the gate fit tightly with the gate groove, and the waterstop is deformed to prevent the gate from leaking.

[0007] In specific applications, when the height H of the guide wheel protruding from the water outlet side of the gate is greater than the thickness D of the water stop by 4mm-6mm, the sealing effect is better; if H is too large relative to D, it is easy to leak on both sides of the gate during the water discharge process. If the height H of the guide wheel protruding from the water outlet side of the gate is not much greater than the thickness D of the water stop or is only 0-3mm higher, the water stop also has the risk of friction due to the processing error between the side of the gate groove and the side of the gate; therefore, when H is 4mm-6mm higher than D, the sealing effect is better, especially when it is 5mm higher, the sealing effect is the best;

[0008] In practical applications, the present application sets a waterstop on the side of the gate, utilizes water pressure to make the gate fit into the gate groove to prevent water leakage, and sets a guide wheel on the side of the gate to effectively protect the waterstop during the gate raising and lowering process; the problem of low service life of the waterstop in the reservoir gate structure is solved; at the same time, the waterstop is set on the side of the gate, which is convenient for maintenance and reduces the maintenance cost of the gate structure.

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] In the description of the present invention, the related terms "up", "down", "left", "right", "inside", "outside" and other directional indications are only based on the orientations shown in the drawings and are used to simplify the present invention for the convenience of description. They are not orientations or structures that the components described must have, and therefore cannot be understood as limitations on the present invention.

[0021] In this embodiment, a water stop gate 1 structure includes a gate 1 and a gate slot 2 that match each other; a water stop strip is provided at the edge of the water outlet side 402 of the gate 1; at the same time, a guide wheel 101 is also provided on the water outlet side 402 of the gate 1, and the turning radius of the guide wheel 101 is greater than the thickness of the water stop strip; a guide wheel slot 201 is provided in the gate slot 2, and the guide wheel 101 corresponds to the guide wheel slot 201.

[0022] In actual application, the present application arranges the waterstop 3 on the side of the gate 1, utilizes the water pressure to make the gate 1 fit with the gate groove 2 to prevent water leakage, and at the same time arranges the guide wheel 101 on the side of the gate 1 to effectively protect the waterstop 3 during the up and down process of the gate 1; solves the problem of low service life of the waterstop 3 in the structure of the reservoir gate 1; at the same time, the waterstop 3 is arranged on the side of the gate 1, which is convenient for maintenance and reduces the maintenance cost of the gate 1 structure.

[0023] Furthermore, in order to improve the stability of the gate 1 in lifting and lowering, and to improve the stability of the gate 1 in sliding along the inner side of the gate slot 2, two or more guide wheels 101 are provided in the present application, and all guide wheels 101 are not in the same straight line along the lifting direction of the gate 1. Similarly, the guide wheel grooves 201 on the inner side of the gate slot 2 are not in the same straight line along the lifting direction of the gate 1. In the present embodiment, four guide wheels 101 are provided, of which the upper two are arranged in parallel and the lower two are arranged in parallel, but the four guide wheels 101 are staggered to facilitate the sliding of the gate 1 up and down. In the present application In order to facilitate the sliding of the guide wheel 101, the guide wheel groove 201 is provided with an arc transition section. When the gate 1 descends, the guide wheel 101 enters the guide wheel groove 201 along the transition section. When the gate 1 rises, the guide wheel 101 slides along the transition section and meets the guide wheel groove 201. After the guide wheel 101 enters the guide wheel groove 201, the guide wheel groove 201 also restricts the guide wheel 101 to prevent it from sliding down again. This is also one of the reasons why the guide wheels 101 are not in the same straight line along the lifting direction of the gate 1. This facilitates the coordination between the gate 1 and the gate groove 2 and improves the sealing performance of the gate 1 structure.

[0024] Furthermore, in order to improve the stability of the gate 1 structure, the outlet side 402 of the gate 1 described in the present application is provided with a protrusion 103. By adding the protrusion 103 to the gate 1, the overall strength of the gate 1 structure is improved, and the stability of the up and down movement of the gate 1 is also improved; in addition, in the present application, the protrusion 103 can also be made of a material different from that of the gate 1, and the protrusion can also be provided with two or more, and the shapes of each protrusion can also be different, for example, a columnar body with a cylindrical, triangular, or polygonal cross-section, and the material of each protrusion can be selected differently, for example, some protrusions are selected from heavy metals, and some protrusions are selected from light metals. Each protrusion can be connected to the gate by a threaded structure or welding. By setting the protrusion, the overall strength of the gate structure can be increased. In actual use, by setting multiple protrusions at the same time, selecting protrusions of different materials, and then matching protrusions of different shapes, the geometric center of gravity and the physical center of gravity of the gate structure are kept consistent, so that the gate can slide freely up and down along the gate groove, thereby improving its operation reliability.

[0025] Further, in order to improve the matching degree between the gate 1 and the gate slot 2, the water stop strip 3 in the present application is a U-shaped structure, and the U-shaped structure means that the water stop strip 3 is provided at the left and right ends and the lower end of the outlet side 402 of the gate 1, such as Figure 5 As shown, the sealing performance of the gate 1 structure of the present application is improved in this way.

[0026] Furthermore, in order to improve the fit between the gate 1 and the inner side of the gate slot 2, the water inlet side 401 of the gate 1 in the present application is provided with a first inclined guide block 102, and the gate slot 2 is provided with a second inclined guide block 202 matching the first inclined guide block 102; the cooperation of the two inclined guide blocks is conducive to the up and down lifting of the gate 1. At the same time, in addition to making the gate 1 fit with the inner side of the gate slot 2 by the pressure of water, the first inclined guide block 102 and the second inclined guide block 202 can also cooperate to make the gate 1 fit more tightly with the inner side of the gate slot 2; wherein the first inclined guide block 102 and the second inclined guide block 202 can both adopt an inclined wedge structure, such as Figure 8 As shown, both can select wedge-shaped blocks with triangular cross-sections, wherein the inclined surface of the first inclined guide block 102 matches the inclined surface of the second inclined guide block 202. During the process of the gate 1 being lifted up and down, the two inclined surfaces slide against each other. A right-angled side of the first inclined guide block 102 is fixed to the water inlet side 401 of the gate 1 by bonding, welding or inlaying, and a right-angled side of the second inclined guide block 202 is fixed to the other inner side surface of the gate 1 by bonding, welding or inlaying. This is convenient to use and allows the gate 1 to fit more tightly with the gate slot 2. In addition, in the specific application of the present application, the angle between the inclined surface of the first inclined guide block 102 and the inner side surface of the gate is 15°. If the angle is too large, the fitting area between the inclined surface of the first inclined guide block 102 and the inclined surface of the second inclined guide block 202 is small, and the gate is prone to unbalance during operation; if the angle is too small, the fitting area between the inclined surface of the first inclined guide block 102 and the inclined surface of the second inclined guide block 202 is too large, and the effect of guiding the gate to move up and down cannot be achieved; when the angle is set to 15°, the operating effect is best.

[0027] Furthermore, since the gate 1 has a large deadweight and is prone to swinging during the lifting process, in the present application, similar to the aforementioned guide wheel 101, two or more first inclined guide blocks 102 may be provided, and all first inclined guide blocks 102 are not in the same straight line along the lifting direction of the gate 1; similarly, the second inclined guide blocks 202 arranged on the inner side surface corresponding to the gate slot 2 are not in the same straight line along the lifting direction of the gate 1; in the present embodiment, a total of 4 first inclined guide blocks 102 and 4 second inclined guide blocks 202 are provided, of which the upper two pairs are arranged in parallel, and the lower two pairs are arranged in parallel, but are staggered to facilitate the up and down sliding of the gate 1; this improves the stability of the gate 1 in lifting and lowering, while facilitating the coordination between the gate 1 and the gate slot 2, and can also improve the sealing of the gate 1 structure.

[0028] Furthermore, if Fig. 9As shown, in order to improve the sealing between the gate 1 and the gate groove 2, in another embodiment of the present application, the bottom of the gate groove 2 includes a first bottom plate 501 and a second bottom plate 502, wherein the first bottom plate 501 is located on the water inlet side 401, and the second bottom plate 502 is located on the water outlet side 402, and the first bottom plate 501 and the second bottom plate 502 are directly provided with a groove 5 for accommodating the gate 1, wherein the side of the groove 5 located on the water outlet side 402 is flush with the inner side surface corresponding to the gate groove 2, the gate falls into the groove 5, and the depth of the groove 5 is greater than the width of the water stop 3; in specific use, the bottom of the gate 1 abuts against the bottom surface of the groove 5, and the gate 1 is pressed against the inner side surface of the gate groove 2 by the pressure of water, wherein the bottom of the gate 1 fits with the side surface corresponding to the groove 5, thereby improving the sealing between the gate 1 and the gate groove 2.

[0029] Furthermore, in another embodiment of the present application, a guide rail is provided on the inner side surface of the gate slot 2, and the guide rail corresponds to the guide wheel, and the guide rail extends downward along the upper end of the gate slot 2 to the guide wheel slot; in actual use, the guide wheel rolls and slides on the guide rail, and by setting the guide rail, the direction in which the gate slides up and down is effectively controlled to prevent interference with the gate slot due to uneven gate hoisting force during the up and down sliding process, thereby improving the reliability of the gate sliding up and down; further, in order to improve the sliding stability, the guide wheel cross-section in the present application is triangular or isosceles trapezoidal, and the guide rail cross-section is also triangular or isosceles trapezoidal, and the guide rail cross-section matches the guide wheel cross-section, and by setting the guide wheel cross-section and the guide rail cross-section to be triangular or isosceles trapezoidal, during specific use, through the pressure of the stored water, when the cross-section is triangular or isosceles trapezoidal, the guide wheel and the guide rail have a higher fit, thereby further improving the reliability of the gate operation.

[0030] The above are preferred embodiments of the present invention. It should be understood that those skilled in the art can derive relevant technical solutions based on the existing technology through logical analysis, reasoning or experiments according to the concept of the present invention without creative work. Therefore, these relevant technical solutions should be within the protection scope of the present claims. For example, in the above drawings and descriptions, although only flat gates are described, the above structure is also applicable to arc gate structures.
