Specific embodiments

[0045] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the specific embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0046] As Figure 1-8 shown, a steel gate for a water conservancy project of the present utility model includes an embedded base 1, a gate body 2, a side seal 3, a plurality of support wheels 4, a sealing plate 5, a bottom seal 6, a lintel 7, a top seal 8 and a side wheel 9, and is used to be installed in a water conservancy building (such as a river channel, a dam opening, etc.) to control the on-off of the water flow in the water conservancy building.

[0047] Among them, the embedded seat 1 is used to be embedded in a hydraulic structure. A sluice opening 101 is penetrated through the embedded seat 1, and the water flow in the hydraulic structure can pass through the sluice opening 101 to pass through this device.

[0048] The gate body 2 is used to block the water flow in the sluice opening 101. A chute 102 is respectively arranged on two opposite side walls in the sluice opening 101, and the gate body 2 is movably arranged between the two chutes 102. As Figure 2 shown, the left and right ends of the gate body 2 are respectively arranged in the two chutes 102. When the gate body 2 is moved downward, the gate body 2 can block the water flow in the sluice opening 101, and when the gate body 2 is moved upward, the water flow can pass through the sluice opening 101.

[0049] The side seal 3 is used to improve the sealing performance between the gate body 2 and the embedded seat 1. The side seals 3 are respectively fixedly arranged on both sides of the gate body 2. Two side seals 3 are arranged on each side of the gate body 2, and each chute 102 is in sealing abutment with the two side seals 3; Figure 1 is shown Figure 2 the structure in the left chute 102, and the structure in the right chute 102 is symmetrical to the structure Figure 1 shown. Four side seals 3 are arranged, and the four side seals 3 are respectively in abutment with two opposite side walls in the two chutes 102, realizing the two-way water stop effect of this steel gate, that is, not only can the water flow be controlled to be turned on and off under normal water flow conditions, but also the problem of water backflow can be avoided during the flood season.

[0050] As Figure 3 shown, the side seal 3 includes a backing plate 31, a pressing plate 32 and a water stop member 33. The backing plate 31 is fixedly arranged on the gate body 2; the pressing plate 32 is fixedly arranged on the side of the backing plate 31 away from the gate body 2; one end of the water stop member 33 is fixedly arranged between the backing plate 31 and the pressing plate 32, and the other end is in abutment with the side wall of the chute 102; the backing plate 31, the pressing plate 32 and the water stop member 33 are preferably connected to the gate body 2 by bolts. The clamping performance of the backing plate 31 and the pressing plate 32 on the water stop member 33 is better, thereby improving the water stop performance of the water stop member 33. At the same time, the fixing of one end of the water stop member 33 by the backing plate 31 and the pressing plate 32 can make the end of the water stop member 33 away from the backing plate 31 project in the chute 102. When the water stop member 33 abuts against the inner wall of the chute 102, the water stop member 33 can be bent towards the direction close to the gate body 2, thereby improving the sealing effect and water stop performance between the water stop member 33 and the inner wall of the chute 102.

[0051] The cross-section of the end of the water stop member 33 away from the backing plate 31 is annular, as Figure 3As shown, one end of the water stop member 33 away from the backing plate 31 is hollow. When the water stop member 33 abuts against the inner wall of the sliding groove 102, the water stop member 33 is more likely to undergo compressive deformation, thereby enhancing the sealing effect and water stop performance of the water stop member 33.

[0052] The support wheels 4 are used to limit the movement of the door body 2. As Figure 1 and Figure 4 shown, a plurality of support wheels 4 are rotatably arranged on the door body 2 and are respectively in rolling connection with two opposite side walls in the gate opening 101. By utilizing the rolling cooperation between the support wheels 4 and the inner wall of the gate opening 101, the lateral movement of the door body 2 can be limited, preventing the door body 2 from undergoing lateral displacement in the sliding groove 102. This can not only prevent the side seal member 3 from disengaging from the sliding groove 102, ensuring the sealing performance between the side seal member 3 and the embedded seat 1, but also reduce the design size of the door body 2. As Figure 1 shown, it is only necessary to arrange the end of the door body 2 in the sliding groove 102, without requiring the outer diameter of the door body 2 to exactly match the distance between the two sliding grooves 102. This reduces the processing difficulty and precision requirements of the door body 2, facilitating the lightweight design of the door body 2.

[0053] As Figure 4 and Figure 5 shown, it is preferable to arrange a plurality of support wheels 4 on the same side of the door body 2. Specifically, a plurality of support wheels 4 are arranged on the downstream side of the door body 2, reducing the contact time between the support wheels 4 and the water body and extending the service life of the support wheels 4.

[0054] The sealing plate 5 is used to enhance the sealing performance between the door body 2 and the embedded seat 1. The sealing plates 5 are respectively fixedly arranged in the sliding grooves 102. Two sealing plates 5 are fixedly arranged in each sliding groove 102. The four sealing plates 5 correspond to the four side seal members 3 one by one and are in sealing contact. As Figure 3 shown, by the contact between the sealing plate 5 and the side seal member 3, the water stop performance between the door body 2 and the embedded seat 1 is enhanced.

[0055] The bottom seal member 6 is used to enhance the sealing performance between the door body 2 and the embedded seat 1. As Figure 7 shown, the bottom seal member 6 is fixedly arranged on the side of the door body 2 away from the support wheels 4 and is in sealing contact with the bottom side in the gate opening 101, thereby enhancing the sealing performance between the bottom side of the door body 2 and the embedded seat 1. The bottom side of the bottom seal member 6 is located below the bottom side of the door body 2. When the door body 2 moves downward and contacts the bottom side in the gate opening 101, the bottom side of the bottom seal member 6 is compressed, enhancing the sealing performance between the bottom seal member 6 and the bottom side in the gate opening 101. At the same time, both ends of the bottom seal member 6 should be connected to the side seal member 3, and the bottom side of the side seal member 3 should be flush with the bottom side of the bottom seal member 6 to enhance the overall sealing performance of the door body 2.

[0056] The lintel 7 is used to enhance the connection firmness between the door body 2 and the embedded base 1. The two ends of the lintel 7 are respectively fixedly arranged on two opposite side walls in the gate opening 101. When the door body 2 moves to the lower part in the gate opening 101, the upper end of the door body 2 abuts against the lintel 7, thereby supporting and stabilizing the door body 2.

[0057] The top seal 8 is used to enhance the sealing performance between the door body 2 and the lintel 7. The top seal 8 is fixedly arranged above the side of the door body 2 away from the support wheel 4 and is in sealing abutment with the lintel 7; both ends of the top seal 8 should also be connected to the side seals 3, and the structure of the bottom seal 6 can be the same as that of the side seals 3.

[0058] The side wheels 9 are used to prevent the door body 2 from rubbing against the inner wall of the chute 102. As Figure 1 、 Figure 4 and Figure 5 shown, multiple side wheels 9 are all rotatably arranged on the door body 2 and are respectively in rolling connection with the two chutes 102. The outer diameter of the side wheels 9 is slightly smaller than the width of the chutes 102.

[0059] As Figure 8 shown, the side wheel 9 includes a wheel shaft 91, a wheel 92 and a baffle 93. The wheel shaft 91 is fixedly sealed on the door body 2. By using their sealed connection, it can prevent water from flowing through the gap between the wheel shaft 91 and the door body 2 through the gate opening 101; the wheel 92 is rotatably arranged on the wheel shaft 91, and the side thereof close to the door body 2 abuts against the wheel shaft 91; an annular groove 901 is formed on the circumferential side of the wheel shaft 91, and the baffle 93 is fixedly arranged on the side of the wheel 92 away from the door body 2 and is rotatably arranged in the annular groove 901. The baffle 93 is preferably composed of two semi-circular plate-like structures, so that it can not only limit the wheel 92, but also facilitate the disassembly, assembly and maintenance of the wheel 92; at the same time, in order to reduce the wear between the wheel 92 and the wheel shaft 91, a wear-resistant bushing can be arranged between them.

[0060] As Figure 4 and Figure 5 shown, the door body 2 includes an upper door leaf 21, a lower door leaf 22, connecting ears 23 and a connecting seal 24. The upper door leaf 21 and the lower door leaf 22 are both arranged between the two chutes 102, and the side seals 3 and the support wheels 4 are both arranged on the upper door leaf 21 and the lower door leaf 22; the connecting ears 23 are respectively fixedly arranged on the upper door leaf 21 and the lower door leaf 22, and the connecting ears 23 on the upper door leaf 21 and the connecting ears 23 on the lower door leaf 22 are detachably and fixedly connected. Setting the door body 2 as a split structure can reduce the processing difficulty and transportation difficulty of the door body 2; the connecting seal 24 is fixedly arranged between the upper door leaf 21 and the lower door leaf 22, thereby enhancing the sealing performance between the upper door leaf 21 and the lower door leaf 22.

[0061] The water stop member 33, the sealing plate 5, the bottom sealing member 6, the top sealing member 8 and the connecting sealing member 24 are preferably made of an elastic rubber material.

[0062] A usage method of a steel gate for a water conservancy project of the present utility model is as follows:

[0063] First, embed and fix the embedded seat 1 in the water conservancy building, install the lintel 7 on the embedded seat 1, then install the gate body 2 between the two sliding grooves 102, and make multiple supporting wheels 4 respectively abut and roll on the two opposite side walls in the gate opening 101. Finally, fix the lifting cable chain to the top end of the gate body 2 to control the lifting movement of the gate body 2 and realize the on-off control of the water flow in the water conservancy building.

[0064] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
