Description

Technical Field

[0001] The utility model relates to a gate used for a water gate, belonging to the field of vertically lifted gates. Background Art

[0002] In water conservancy projects, the water discharge gate is usually set up to ensure the safety of the main canal. Since the gate in the water discharge gate is located underwater, the gate is usually equipped with a top water stop component and side water stop components on both sides. For the water discharge gate with a breast wall, a lintel is usually set at the bottom of the breast wall, and a sealing surface is set on the lintel to seal with the top water stop component and the side water stop component. When the gate is fully closed to block water, the top water stop component and the side water stop components on both sides are sealed with the sealing surface of the lintel to ensure the sealing of the gate. The water discharge gate is sometimes also used for ecological water replenishment to meet the water demand of places along the line. However, when the water discharge gate is used for ecological water replenishment, the gate opening will exceed the height of the sealing surface, causing the top water stop assembly to separate from the lintel sealing surface. At this time, the top of the gate is still below the water surface. Therefore, in addition to flowing out from the bottom of the gate, water will also flow out from the top of the gate through the gap between the gate and the lintel, causing the gate to have a double-layer flow at the top and bottom, which will cause gate vibration and gate slot cavitation, reducing the service life of the gate. Therefore, it is necessary to modify the top water stop structure of the water discharge gate to ensure the sealing of the top of the gate when the gate is at a small opening (where "small opening" refers to an opening range where the top water stop structure is separated from the lintel sealing surface but the top of the gate is still below the water surface) to meet the needs of ecological water replenishment of the water discharge gate.

[0003] In the prior art, a submerged hole emergency gate that prevents water from shooting is disclosed in a Chinese utility model patent with authorization announcement number CN211816115U and authorization announcement date 2020.10.30. The emergency gate is arranged between the breast wall and the downstream gate wall, and the flood discharge tunnel is located at the lower part of the breast wall and the downstream gate wall. The water-stop structure on the emergency gate includes a top water-stop assembly arranged at the top and side water-stop assemblies arranged on both sides. An upstream lintel is buried at the bottom of the breast wall. The upstream lintel includes an upstream lintel vertical surface and a water-stop seat plate welded to the vertical surface of the upstream lintel (the surface of the water-stop seat plate constitutes the sealing surface of the lintel). The top water-stop assembly and the water-stop seat plate are sealed to ensure the sealing of the top of the gate, so that when the gate is fully closed to block water, water cannot pass through the top of the gate. In order to solve the problem of gate vibration and gate groove cavitation caused by water overflow at the top of the gate when the top water stop assembly is separated from the water stop seat plate, this patent arranges multiple water baffles on the panel of the gate. The water baffles are evenly arranged on the panel below the top water stop assembly. The spacing between adjacent water baffles is less than the height of the vertical plane of the upstream lintel. The spacing between the water baffle and the vertical plane of the upstream lintel is less than 15mm, and the length of the water baffle is greater than the hole width of the flood discharge tunnel. Therefore, during the closing process of the gate, the water baffle can be used to block the water flowing upward along the gap between the panel and the breast wall, reducing the amount of water flowing over the top of the gate, thereby reducing the vibration of the gate body caused by the overflow at the top of the gate, and protecting the top water stop assembly from impact to a certain extent, thereby extending its service life.

[0004] However, the above-mentioned water retaining plate does not contact the gate lintel when in use, that is, the gate cannot be completely sealed during the process of opening and closing the gate, so it can only reduce the flow at the top of the gate, so as to reduce the degree of gate body vibration and gate slot cavitation. When the water discharge gate is used for ecological water replenishment, it needs to operate at a small opening for a long time, which will still cause serious gate body vibration and gate slot cavitation problems over time. Utility Model Content

[0005] The utility model aims to provide a gate for a water gate, so as to solve the problems that there is a gap between the existing water retaining plate and the lintel, the top overflow phenomenon still exists, and the gate still suffers from serious door body vibration and door slot cavitation when the gate is operated at a small opening for a long time.

[0006] In order to achieve the above-mentioned purpose, the gate used for the water gate in the utility model adopts the following technical solutions:

[0007] A gate for a sluice gate comprises a gate body, wherein a top water stop piece for sealingly cooperating with a lintel sealing surface is provided on the top of the gate body, and the characteristic is that a relay water stop piece for sealingly cooperating with the lintel sealing surface is provided on the gate body below the top water stop piece; the relay water stop piece is provided with one piece, and the spacing between the relay water stop piece and the top water stop piece satisfies that it is less than the upper and lower heights of the lintel sealing surface and the sum of the upper and lower heights of the lintel sealing surface is not less than the gate opening; or the relay water stop piece is provided with at least two pieces above and below, and the spacing between the uppermost relay water stop piece and the top water stop piece and the spacing between adjacent relay water stops both satisfy that they are less than the upper and lower heights of the lintel sealing surface, and the sum of the spacing between the lowermost relay water stop piece and the top water stop piece and the upper and lower heights of the sealing surface is not less than the gate opening.

[0008] The beneficial effect of the above technical solution is that: the utility model belongs to an improved invention, and a relay water stop is provided below the top water stop on the door body for sealing with the door lintel sealing surface. When one relay water stop is provided, the distance between the relay water stop and the top water stop is less than the upper and lower heights of the door lintel sealing surface; when at least two relay water stops are provided, the distance between the top relay water stop and the top water stop and the distance between adjacent relay water stops are less than the upper and lower heights of the door lintel sealing surface. Thus, before the gate top water stop is about to separate from the door lintel, the relay water stop can seal with the door lintel sealing surface, or before the upper relay water stop is about to separate from the door lintel sealing surface, the lower adjacent relay water stop can seal with the door lintel sealing surface. At the same time, when there is one relay water stop, the sum of the distance between the relay water stop and the top water stop and the upper and lower heights of the lintel sealing surface is not less than the gate opening, so as to ensure that when the gate is at the required opening, the relay water stop can be sealed with the lintel sealing surface; when there are at least two relay water stops, the sum of the distance between the bottom relay water stop and the top water stop and the upper and lower heights of the sealing surface is not less than the gate opening, so as to ensure that when the gate is at the required opening, the bottom relay water stop can be sealed with the lintel sealing surface. Thus, overflow at the top of the gate is avoided, thereby solving the problem of door body vibration and gate slot cavitation caused by overflow at the top.

[0009] Furthermore, side water stops are respectively provided on the left and right sides of the door body, and the left and right ends of the top water stop and the side water stops as well as the left and right ends of the relay water stop and the side water stops are respectively sealed and connected.

[0010] Furthermore, the left and right ends of the top water stop and the side water stop as well as the left and right ends of the relay water stop and the side water stop are connected respectively through corner water seals.

[0011] Furthermore, the top water stop and the relay water stop are respectively fixed to the door body by a plurality of bolts, and a plurality of bolt through holes are respectively provided on the top water stop and the relay water stop, and each bolt through hole is interference fit with the rod of the corresponding bolt.

[0012] Furthermore, the top water stop and the relay water stop are respectively fixed to the door body by multiple bolts, and elastic pads are respectively arranged between the top water stop and the relay water stop and the door body. Multiple bolt through holes are respectively opened on the top water stop, the relay water stop and the corresponding elastic pads, and the rods of the corresponding bolts in each bolt through hole on the elastic pad are interference fit.

[0017] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0018] In view of the technical problems existing in the prior art, the basic technical concept of the utility model is: a relay water stop is provided below the top water stop of the gate for sealing with the lintel sealing surface, and the relay water stop can be provided with one or more. When one relay water stop is provided, the distance between the relay water stop and the top water stop is less than the upper and lower heights of the lintel sealing surface; when at least two relay water stops are provided, the distance between the topmost relay water stop and the top water stop and the distance between adjacent relay water stops are less than the upper and lower heights of the lintel sealing surface, so that before the top water stop of the gate is about to separate from the lintel sealing surface, the relay water stop can seal with the lintel sealing surface, or before the upper relay water stop is about to separate from the lintel sealing surface, the lower adjacent relay water stop can seal with the lintel sealing surface. At the same time, when one relay water stop is provided, the sum of the distance between the relay water stop and the top water stop and the upper and lower heights of the lintel sealing surface is not less than the gate opening, so as to ensure that when the gate is at the required opening, the relay water stop can be sealed with the lintel sealing surface; when at least two relay water stops are provided, the sum of the distance between the lowest relay water stop and the top water stop and the upper and lower heights of the sealing surface is not less than the gate opening, so as to ensure that when the gate is at the required opening, the lowest relay water stop can be sealed with the lintel sealing surface. Therefore, when the gate is in a long-term small opening operation, there will be no problems of door body vibration and gate groove cavitation due to top overflow.

[0019] Embodiment 1 of the gate for a water gate in the utility model:

[0020] In this embodiment, the sluice gate is a water discharge gate. Figure 1 As shown, the water discharge gate is a structural type with a breast wall. The water discharge gate includes a gate 1, a breast wall 9 and a lintel 10. The lintel 10 is arranged on the breast wall 9.

[0021] like Figure 2As shown, the gate 1 includes a gate body 3, and a top water stop 4 is provided on the top of the gate body 3. When the gate 1 is fully closed to block water, the top water stop 4 on the gate 1 can be sealed with the sealing surface on the lintel 10 to seal the top of the gate 1 to ensure that water does not flow through the top of the gate 1. A relay water stop 5 is provided below the top water stop 4. In this embodiment, only one relay water stop 5 is provided. The distance between the top water stop 4 and the relay water stop 5 is less than the height of the sealing surface of the lintel 10. Therefore, during the opening process of the gate 1, before the top water stop 4 is about to separate from the sealing surface of the lintel 10, the relay water stop 5 can be sealed with the sealing surface of the lintel 10 to maintain the sealing of the top of the gate 1 during the opening process, so that water does not flow through the top of the gate. At the same time, the sum of the distance between the top water stop 4 and the relay water stop 5 and the upper and lower heights of the sealing surface of the lintel 10 is not less than the opening of the gate 1, so that when the gate 1 reaches the required small opening and operates at a small opening for a long time, the sealing surface of the lintel 10 will not be separated from the relay water stop 5, that is, the relay water stop 5 can always be in a sealed matching state with the sealing surface of the lintel 10. Therefore, during the opening process and the long-term small opening operation of the gate 1, its top can always be in a sealed state, so that the door body vibration and door groove cavitation will not be caused by water overflowing from the top.

[0022] In addition, under ideal conditions, when the gate is fully closed to block water, the top water stop 4 is sealed with the lowest end of the sealing surface of the lintel 10. At this time, the sum of the distance between the top water stop 4 and the relay water stop 5 and the upper and lower heights of the sealing surface of the lintel 10 can be equal to the opening of the gate 1. For example, the upper and lower heights of the sealing surface of the lintel 10 are set to 800mm, and the distance between the top water stop 4 and the relay water stop 5 can be set to 660mm. At this time, it can be ensured that when the gate 1 opening is within 1460mm, the top of the gate 1 will not flow through the water, and the long-term operation will not cause the problem of door body vibration and door groove cavitation. Of course, it is also possible not to set it according to the above data. The distance between the top water stop 4 and the relay water stop 5 and the upper and lower heights of the sealing surface of the lintel 10 can be designed according to the actual gate opening requirements.

[0023] like Figure 2 As shown, side water stoppers 6 are respectively provided on both sides of the gate 1 to ensure that water does not flow through the two sides of the gate 1. Both ends of the top water stopper 4 and the relay water stopper 5 are respectively sealed and connected with the corresponding side water stopper 6, and a corner water seal (not shown in the figure) is provided at the connection. The top water stopper 4 and the relay water stopper 5 are respectively sealed and connected with the side water stopper 6 through the corner water seal, thereby ensuring the overall sealing of the top water stopper 4 and the relay water stopper 5. In this embodiment, the connection between the corner water seal and the top water stopper 4, the relay water stopper 5 and the side water stopper 6 adopts a raw rubber hot vulcanization bonding method.

[0024] like Figure 3As shown, elastic pads 8 are respectively arranged between the top water stop 4 and the relay water stop 5 and the gate body 3, and the elastic pads 8 can make the top water stop 4 and the relay water stop 5 more firmly fixed on the gate 1 to improve the sealing of the gate 1. The other side of the top water stop 4 and the relay water stop 5 is respectively provided with a pressure plate 2, which can make the top water stop 4 and the relay water stop 5 pressed more tightly against the gate, further improving the sealing of the top of the gate 1. The top water stop 4 and the relay water stop 5 are fixed to the gate 1 through the corresponding elastic pad 8, the corresponding pressure plate 2 and a plurality of bolts 7, respectively. The pressure plate 2, the top water stop 4, the relay water stop 5 and the elastic pad 8 are respectively provided with a plurality of bolt holes in the same position, wherein the top water stop 4, the relay water stop 5 and the elastic pad 8 are all made of rubber material, and each bolt hole on the top water stop 4, the relay water stop 5 and the elastic pad 8 and the rod of the corresponding bolt 7 are interference fit to ensure that the bolt hole does not leak, thereby improving the sealing of the top of the gate 1. Each bolt hole on the pressure plate 2 and the rod of the corresponding bolt 7 are clearance fit, and the pressure plate 2 can make the top water stop 4, the relay water stop 5 and the corresponding elastic pad 8, as well as the elastic pad 8 and the door body 3 pressed tighter, so that the sealing of the top of the gate 1 is better. When installing the bolts 7 on the top water stop 4 and the relay water stop 5, start installing and tightening the bolts 7 in the middle, and then tighten the bolts 7 on both sides alternately to evenly press the top water stop 4 and the relay water stop 5 to make their surfaces smoother and the sealing effect better.

[0025] Working principle: When the gate 1 is fully closed to block water, the top water stop 4 and the sealing surface of the lintel 9 are sealed to ensure that water does not flow through the top of the gate 1. A relay water stop 5 is arranged below the top water stop 4. The distance between the relay water stop 5 and the top water stop 4 is less than the upper and lower heights of the sealing surface of the lintel 10. When the gate 1 is opened upward, the relay water stop 5 can press and contact with the sealing surface before the top water stop 4 and the sealing surface of the lintel 9 are about to separate, and continue to maintain the sealing of the top of the gate 1. At the same time, the sum of the distance between the relay water stop 5 and the top water stop 4 and the upper and lower heights of the sealing surface of the lintel 10 is not less than the gate opening, so that after the gate 1 reaches the required small opening, the relay water stop 5 does not separate from the sealing surface of the lintel 9. Therefore, when the gate 1 is in the required small opening state for a long time, the top of the gate 1 can be in a sealed state, and there will be no top water flow phenomenon, and then there will be no problems of door body vibration and door groove cavitation.

[0026] Embodiment 2 of the gate for a water gate in the utility model:

[0027] The difference between this embodiment and embodiment 1 is that the relay water stop in this embodiment is provided with more than two. Among them, the spacing between the top relay water stop and the top water stop and the spacing between adjacent relay water stops are all less than the upper and lower heights of the lintel sealing surface. Therefore, during the opening process of the gate, before the top water stop is about to separate from the lintel sealing surface, the relay water stop can be sealed with the lintel sealing surface, or before the upper relay water stop is about to separate from the lintel sealing surface, the lower adjacent relay water stop can be sealed with the lintel sealing surface to maintain the sealing of the top of the gate during the gate opening process, so that water does not flow through the top of the gate. At the same time, the sum of the spacing between the bottom relay water stop and the top water stop and the upper and lower heights of the sealing surface is not less than the required small opening of the gate. Therefore, when the gate reaches the required small opening, the lintel sealing surface can be sealed with a relay water stop, and the lintel sealing surface will not be separated from the lowest relay water stop after the gate reaches the required small opening, causing water to flow through the top of the gate, resulting in gate body vibration and gate slot cavitation. In addition, under ideal conditions, when the gate is fully closed to block water, the top water stop seals with the lowest end of the lintel sealing surface. At this time, the sum of the distance between the top water stop and the lowest relay water stop and the upper and lower heights of the lintel sealing surface can be equal to the gate opening.

[0028] The specific number of relay water stop fittings can be two, three or four, and of course it can be more, which is mainly determined by the upper and lower heights of the lintel sealing surface. When the upper and lower heights of the lintel sealing surface are small, the number of relay water stop fittings set is more; when the upper and lower heights of the lintel sealing surface are moderate, the number of relay water stop fittings set is less.

[0029] In other embodiments, when setting the connection relationship between the gate top water stop and the side water stop and between the relay water stop and the side water stop, the top water stop, the relay water stop and the side water stop can be directly injection molded into an integrated structure.

[0030] In other embodiments, when setting the connection method between the gate top water stop and the side water stop and between the relay water stop and the side water stop, corner water seals may not be provided, so that the top water stop and the side water stop and between the relay water stop and the side water stop are directly sealed and connected through the raw rubber hot vulcanization bonding method.

[0031] In other embodiments, when setting the matching relationship between each bolt through-hole on the top water stop and the relay water stop and the corresponding bolt rod, interference fit may not be used. In this case, the top water stop and the relay water stop need to be pressed tighter against the corresponding elastic pad to ensure that there is no gap between the top water stop and the relay water stop and the elastic pad, so that water cannot pass through, thereby ensuring the sealing of the top of the gate.

[0032] In other embodiments, when setting the matching relationship between each bolt through-hole on the elastic pad and the rod of the corresponding bolt, interference fit may not be used. In this case, the top water stop and the relay water stop need to be pressed tighter against the corresponding elastic pad, and the elastic pad and the gate need to be pressed tighter, so as to ensure that there are no gaps between the top water stop and the relay water stop and the corresponding elastic pad, and between the elastic pad and the gate, so that water cannot pass through, thereby ensuring the sealing of the top of the gate.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
