Description

Technical Field

[0001] The present invention relates to the technical field of gates, and in particular to a plane gate leaf. Background Art

[0002] A flat gate is a common type of gate in water conservancy projects. It includes a door leaf, and water-stop rubber is arranged on the left and right sides and the lower part near the edge of one side of the door leaf. Gate frames are arranged on both sides of the door leaf. A beam plate is arranged between the lower parts of the two gate frames (used to cooperate with the water-stop rubber at the lower part of the door leaf to play a sealing role). It also includes a hoist that can lift the door leaf. In the process of lowering the door leaf, when the door leaf acts on the closed inclined iron arranged on one side of the gate frame (at this time the door leaf is about to fall to the bottom), the door leaf will be pushed to the side where the water-stop rubber is arranged, so that the water-stop rubber contacts with the side of the gate frame to play a sealing role. However, since the water-stop rubber needs to have a certain amount of compression to have a sealing effect, the door leaf will continue to drop a certain distance after the water-stop rubber contacts with the gate frame, resulting in relative sliding between the water-stop rubber and the gate frame in the up and down directions, and the water-stop rubber will have a certain wear. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a flat gate leaf in view of the above-mentioned technical deficiencies.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a flat gate leaf, including a sealing plate and a support plate, a water-stop rubber is arranged on the side of the sealing plate away from the support plate, the side of the sealing plate away from the support plate is inclined outward from top to bottom and a hanging plate is arranged on the top of this side, a groove is arranged on the side of the hanging plate close to the sealing plate, the side of the support plate close to the sealing plate is inclined inward from top to bottom, a top plate which can be inserted into the groove is arranged on the top of the support plate, and a plurality of main wheels are arranged on both sides of the support plate in the width direction.

[0005] To further optimize the technical solution, a lifting lug is further provided on the top of the support plate.

[0006] To further optimize the technical solution, screws are provided on both sides of the top of the support plate.

[0007] To further optimize the technical solution, pull-up plates are provided on both sides of the sealing plate in the width direction, a round rod is provided on the side of the pull-up plate close to the support plate, push grooves are provided on both sides of the support plate in the width direction, the round rod is located in the push groove, the upper part of the push groove close to the sealing plate is a pushing surface, and the lower part is a retaining surface, the pushing surface gradually moves away from the sealing plate in the direction from top to bottom, and the retaining surface can act with the round rod to keep the upper part of the sealing plate in a posture of falling toward the top of the support plate.

[0008] To further optimize the technical solution, pull-down plates are provided on both sides of the sealing plate in the width direction, a locking plate is provided on the side of the pull-down plate close to the supporting plate, receiving grooves are provided on both sides of the supporting plate in the width direction, the locking plate is located in the receiving groove, a receiving cavity is provided at the lower part of the receiving groove, the receiving cavity is located on the side of the receiving groove close to the sealing plate, a rotating plate is provided in the receiving cavity, an axial hole is provided on the rotating plate, a pad and a weight are provided on both sides of the axial hole of the rotating plate, and the head of the pad extends out of the receiving groove.

[0009] Compared with the prior art, the present invention has the following advantages: the side of the sealing plate away from the supporting plate is inclined outward from top to bottom, and the side of the supporting plate close to the sealing plate is inclined inward from top to bottom. After the door leaf of the present application is installed on the gate, when the gate is closed, the sealing plate can first fall on the bottom plate, and then the supporting plate continues to fall to push the sealing plate to one side of the gate frame for sealing. Since the water-stop rubber on the sealing plate does not slide relative to the gate frame during this process, the wear is relatively small. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose, technical solution and advantages of the present invention more clear, the technical solution will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0019] Specific implementation method: Combination Figure 1-7 As shown, a flat gate leaf comprises a sealing plate 1 and a supporting plate 2, wherein a waterproof rubber is arranged on one side of the sealing plate 1 away from the supporting plate 2, and the waterproof rubber is arranged on both sides and the lower edge of the sealing plate 1 close to the width direction, and the side of the sealing plate 1 away from the supporting plate 2 is inclined outward from top to bottom (hereinafter referred to as the side as the pressure-bearing surface) and a hanging plate 11 is arranged on the top of the side, and the hanging plates 11 are preferably two, and a groove is arranged on the bottom of the side of the hanging plate 1 close to the sealing plate 1, and the supporting plate 2 close to the sealing plate 1 One side is inclined inward from top to bottom (hereinafter referred to as the pressure surface), and a top plate 21 that can be inserted into the groove is arranged on the top of the support plate 2. The top of the top plate 21 is preferably semi-cylindrical, and correspondingly, the groove is arc-shaped and its radius is slightly larger than the radius of the top of the top plate 21. In order to facilitate the insertion of the top plate 21 into the groove, a slope is arranged on the side of the groove away from the sealing plate 1. The slope is inclined toward the bottom of the groove in the direction from away from the sealing plate 1 to close to the sealing plate 1. The support plate 2 is provided with a plurality of main wheels 24 on both sides in the width direction. When in use, combined with Figure 7 As shown, the door leaf of the present application is installed in the gate frame 3, the top of the support plate 2 is connected to the opening and closing device so that it can be raised and lowered, and the outer diameter of the main wheel 24 is slightly smaller than the length of the slide groove on the gate frame 3 ( Figure 7 The left and right directions are the length directions of the slide slots and the thickness directions of the door leaves), so that the left and right displacements of the support plate 2 during lifting are very small. When the gate is fully opened, the door leaves are in Figure 1 In the state shown, the top plate 21 is inserted into the groove, the pressure-bearing surface and the pressure-applying surface are in contact (at this time, the side of the sealing plate 1 provided with the water-stop rubber is in a vertical state), the water-stop rubber does not contact the left side of the slide groove on the gate frame 3, and there is a certain gap between the two. When the gate is closed, the support plate 2 descends, and the sealing plate 1 also descends synchronously. When the lower end of the sealing plate 1 falls on the bottom plate 4 at the bottom of the gate frame 3, it stops descending, while the support plate 2 continues to descend, thereby pushing the sealing plate 1 to the left. When the water-stop rubber on the sealing plate 1 is in close contact with the left side of the slide groove on the gate frame 3, the support plate 2 is still not in contact with the bottom plate 4 and it cannot continue to descend. When the gate is opened (the left side of the sealing plate 1 faces the side with high water level), the support plate 2 rises. Under the action of water pressure, the sealing plate 1 moves to the right so that the pressure-bearing surface and the pressure-applying surface are in contact. When the top plate 21 is fully inserted into the groove, the water-stop rubber on the sealing plate 1 is completely separated from the left side of the slide groove on the gate frame 3. After that, the support plate 2 continues to rise, which will drive the sealing plate 1 to rise. In the above process, since the water-stop rubber on the sealing plate 1 does not slide relative to the gate frame 3, the wear is small.

[0020] Specifically, a lifting lug 22 is provided on the top of the support plate 2. The lifting lug 22 is used to connect the wire rope on the hoist on the opening and closing device.

[0021] Furthermore, the sealing plate 1 is provided with a support strip (not shown in the figure) on one side of the water-stop rubber and its edge, and the surface of the support strip is lower than the surface of the water-stop rubber by a certain height. When the support strip contacts the gate frame 3, the water-stop rubber cannot be further compressed.

[0022] Furthermore, a plurality of side wheels are provided on both sides of the support plate 2 in the width direction to prevent the support plate 2 from shifting in the width direction.

[0023] Furthermore, upper pull plates 12 are provided on both sides of the sealing plate 1 in the width direction. The upper pull plates 12 are located at the upper part of the sealing plate 1. The distance between the two upper pull plates 12 is equal to or slightly larger than the width of the support plate 2, which can play a limiting role and prevent the sealing plate 1 from sliding significantly in the width direction relative to the support plate 2.

[0024] Combination Figure 7 As shown, when the water level difference on both sides of the gate is very small or the water level on the right side of the gate is higher, when the support plate 2 just starts to rise, the sealing plate 1 does not move. As the support plate 2 rises, the pressure-bearing surface and the pressure-exerting surface separate, and the distance between the two in the thickness direction becomes larger. At this time, the top plate 21 may be difficult to insert into the groove on the hanging plate 11. In this case, a round rod is required to be provided on the side of the upper pull plate 12 close to the support plate 2. Both sides of the support plate 2 in the width direction are provided with a push groove 23. The round rod is located in the push groove 23. The upper part of the push groove 23 close to the sealing plate 1 is a push surface, and the lower part is a retaining surface. The push surface gradually moves away from the sealing plate 1 from top to bottom. When the sealing plate 1 does not move and the support plate 2 rises to a certain height, the push surface contacts the round rod, and the support plate 2 continues to rise. The top of the sealing plate 1 will be pulled to tilt toward the top of the support plate 2. The retaining surface can act with the round rod to keep the upper part of the sealing plate 1 tilted toward the top of the support plate 2, so that the subsequent top plate 21 can be inserted into the groove on the hanging plate 11. When the top plate 21 is fully inserted into the groove, the sealing plate 1 is pulled up by the upward pulling force. When it is pulled up, its bottom almost does not generate friction with the bottom plate 4. In addition, when the water level on the right side of the gate is high, the additional pulling force required by the gate opening machine due to water pressure when raising the gate leaf is small.

[0025] Furthermore, a pull-down plate 13 is provided on both sides of the sealing plate 1 in the width direction, a locking plate is provided on the side of the pull-down plate 13 close to the supporting plate 2, the thickness of the locking plate is greater than the maximum horizontal displacement between the sealing plate 1 and the supporting plate 2, a receiving groove 25 is provided on both sides of the supporting plate 2 in the width direction, the locking plate is located in the receiving groove 25, and the locking plate will not touch the two sides of the receiving groove 25 during the relative displacement between the sealing plate 1 and the supporting plate 2, a receiving cavity 27 is provided at the lower part of the receiving groove 25, the receiving cavity 27 is located on the side of the receiving groove 25 close to the sealing plate 1, a rotating plate 26 is provided in the receiving cavity 27, an axial hole 262 is provided on the rotating plate 26, and a pad 261 and a weight 263 are respectively provided on both sides of the axial hole 262 of the rotating plate 26, the axial hole 262 is rotatably connected to the pin shaft on the support plate 2 (the diameter of the axial hole 262 is slightly larger than the diameter of the pin shaft), and the head of the pad 261 extends into the receiving groove 25. The end of the accommodating cavity 27 close to the accommodating groove 25 is narrower, slightly larger than the thickness of the pad 261, and the end of the accommodating cavity 27 away from the accommodating groove 25 is wider and can accommodate the heavy object 263. The accommodating cavity 27 has a certain height, so that the rotating plate 26 can rotate within a certain range. Figure 6 As shown, after the weight 263 contacts the bottom surface of the accommodating chamber 27, it cannot continue to rotate in the same direction. At this time, the pad 261 is tilted upward, and its end away from the shaft hole 262 is higher. After the gate is closed, the lock plate is located at the upper part of the accommodating groove 25. When the gate is opened, due to the thickness of the lock plate (its thickness direction is the same as the thickness direction of the sealing plate 1) is larger, the pad 261 is always located between the side of the lock plate away from the sealing plate 1 and the side of the accommodating groove 25 close to the sealing plate 1. In the process from when the support plate 2 just starts to rise to when the sealing plate 1 just starts to rise, when the pressure-applying surface and the pressure-bearing surface are not separated, the pad 261 will enter the side of the lock plate and the accommodating groove 25 close to the sealing plate 1 (it is designed that when the top plate 21 is inserted into the groove and the pressure-applying surface and the pressure-bearing surface are in contact, the pad 261 is located between the lock plate and the side of the accommodating groove 25 close to the sealing plate 1, and at this time the pad 261 and The gap between the locking plates is small), and when the pressure-applying surface and the pressure-bearing surface are separated, when the support plate 2 rises to a certain height, the lower end of the locking plate presses down the end of the pad 261 away from the shaft hole 262. At a certain moment, when the pressure-applying surface and the pressure-bearing surface are in contact, the locking plate slides relative to the pad 261 so that the pad 261 is separated from the lower part of the locking plate and aligned with the side of the locking plate and the receiving groove 25 close to the sealing plate 1. Under the action of the weight 263, the rotating plate 26 rotates so that the pad 261 enters between the quasi-locking plate and the side of the receiving groove 25 close to the sealing plate 1, thereby greatly reducing the space between the two. When the sealing plate 1 is raised, the sealing plate 1 shakes less when it is affected by water flow or wind.

Any simple modification, change and equivalent structural transformation made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the technical solution of the present invention.
