Description

Technical Field

[0001] The present application relates to the field of water conservancy projects, and more particularly to an integrated gate for a circular culvert pipe. Background Art

[0002] Culvert-type sluice gates (culvert sluices) are commonly used in sluice gates with relatively high water levels and small orifice sizes. The flow through the gate is controlled by the low water level and is widely used in water diversion irrigation and cross-dike drainage in water conservancy projects. The cross-dike culvert pipes in culvert sluices generally come in two forms: rectangular and circular.

[0003] In the prior art, when a circular culvert pipe is adopted, a circular gate is often used in combination. However, due to the poor sealing between the circular gate and the gate slot and the relatively poor water-stop effect, leakage occurs in the gate. How to solve the above technical problems is what those skilled in the art need to consider. Summary of the Utility Model

[0004] The present application provides an integrated gate for a circular culvert pipe to solve the problem of how to reduce leakage of the gate.

[0005] An embodiment of the present application provides an integrated gate for a circular culvert pipe, which includes a retaining wall, a doorframe, a door leaf, and a first water-stop block. The retaining wall includes a culvert wall and a gate wall. The culvert wall is used for installing a circular culvert pipe. The gate wall is arranged at the water inlet end of the circular culvert pipe. The gate wall is fixedly connected to the culvert wall and forms a groove. The doorframe is arranged in the groove, and the doorframe fits against the side wall of the groove. The door leaf is movably connected to the doorframe, and the door leaf is used to close or open the water inlet end of the circular culvert pipe. The first water-stop block is arranged at both ends of the door leaf along the horizontal direction, and the first water-stop block is used to seal the door leaf and the doorframe when the door leaf closes the water inlet end of the circular culvert pipe.

[0006] Compared with the prior art, the integrated gate for a circular culvert pipe provided in this embodiment is formed by connecting and enclosing the culvert wall and the gate wall to form a groove. The groove is used to place the doorframe. The doorframe and the door leaf cooperate to close the water inlet end of the circular culvert pipe. By arranging the first water-stop block on the side of the door leaf close to the circular culvert pipe, the first water-stop block seals the gap between the door leaf and the doorframe, so as to achieve the effect of reducing leakage of the gate.

[0007] In a possible implementation manner, the integrated gate for a circular culvert pipe further includes a threshold, and the threshold is arranged on the bottom wall of the groove and cooperates with the bottom surface of the door leaf.

[0008] In a possible implementation manner, the integrated gate for a circular culvert pipe further includes a second water-stop block, and the second water-stop block is arranged at the position of the door leaf close to the threshold, and the second water-stop block is used to seal the door leaf and the threshold.

[0009] In a possible embodiment, the integrated gate for the circular culvert further includes a third water stop block, which is disposed at the top of the gate leaf. The third water stop block extends from the gate leaf to above the water inlet end of the circular culvert, and the third water stop block is used to fit with the culvert wall to seal the gate leaf and the culvert wall.

[0010] In a possible implementation, the third water stop block includes a ball head and a connecting portion that are integrally connected, the connecting portion is fixedly connected to the door leaf, and the ball head protrudes from the connecting portion toward the culvert wall.

[0011] In a possible implementation, the integrated gate for the circular culvert further includes a hoist, which is transmission-connected to the gate leaf, and is used to drive the gate leaf to move so that the gate leaf approaches or moves away from the door frame.

[0012] In a possible implementation, the integrated gate for a circular culvert further includes a platform, the platform and the gate wall are spaced apart in a vertical direction, the platform is integrally connected to the culvert wall, and the platform is used to place the gate hoist.

[0013] In a possible embodiment, the door leaf includes a panel and a beam plate, the panel is used to correspond to the water inlet end of the circular culvert, the beam plate is fixedly connected to the side of the panel opposite to the circular culvert, and the side of the panel close to the circular culvert is fixedly connected to the first water stop block.

The gate wall 112 is arranged at the inlet end 41 of the circular culvert 4. The gate wall 112 is fixedly connected to the culvert wall 111 and forms a groove 116. The door frame 13 is arranged in the groove 116, and the door frame 13 is attached to the groove side wall 117 of the groove 116. The door leaf 14 is movably connected to the door frame 13. The door leaf 14 is used to close or open the inlet end 41 of the circular culvert 4. The first water stop block 17 is arranged at both ends of the door leaf 14 along the horizontal direction 2. The first water stop block 17 is used to seal the door leaf 14 and the door frame 13 when the door leaf 14 closes the inlet end 41 of the circular culvert 4.

[0024] Water flows from the side of the culvert wall 111 opposite to the circular culvert 4 towards the inlet end 41 of the circular culvert 4. The door leaf 14 is used to close or open the inlet end 41 of the circular culvert 4. The water flow direction 5 is from left to right as shown in Figure 2 the figure.

[0025] The integrated gate 1 for a circular culvert provided in this embodiment is connected to the gate wall 112 through the culvert wall 111 and encloses to form a groove 116. The groove 116 is used to place the door frame 13. The door frame 13 cooperates with the door leaf 14 to close the water inlet end 41 of the circular culvert 4. By arranging a first water stop block 17 on the side of the door leaf 14 close to the circular culvert 4, the first water stop block 17 seals the gap between the door leaf 14 and the door frame 13 to reduce the leakage of the gate.

[0026] In this embodiment, the gate wall 112 includes a first wall body 113, a second wall body 114, and a third wall body 115 connected in sequence. The first wall body 113 and the third wall body 115 are arranged at intervals along the horizontal direction 2, and the circular culvert 4 is located between the first wall body 113 and the third wall body 115. The second wall body 114 is arranged below the circular culvert 4 along the vertical direction 3. One end of the second wall body 114 is connected to the first wall body 113, and the other end is connected to the third wall body 115.

[0027] The first wall body 113, the second wall body 114, and the third wall body 115 are respectively connected to the culvert wall 111 and enclose to form a groove 116. The opening direction of the groove 116 faces upward along the vertical direction 3.

[0028] The door frame 13 includes a first frame body 131 and a second frame body 132. The first frame body 131 and the second frame body 132 are arranged opposite to each other along the horizontal direction 2, and the first frame body 131 and the second frame body 132 are respectively located on the groove side walls 117 of the groove 116. The first frame body 131 is attached to the first wall body 113, and the first frame body 131 is fixedly connected to the culvert wall 111. The second frame body 132 is attached to the third wall body 115, and the second frame body 132 is fixedly connected to the culvert wall 111.

[0029] One end of the door leaf 14 is movably connected to the first frame body 131 along the vertical direction 3, and the other end is movably connected to the second frame body 132 along the vertical direction 3. Thus, the door leaf 14 approaches the circular culvert 4 along the vertical direction 3 to close the water inlet end 41 of the circular culvert 4, or the door leaf 14 moves away from the circular culvert 4 along the vertical direction 3 to open the water inlet end 41 of the circular culvert 4.

[0030] The first water stop block 17 extends along the vertical direction 3, and there are two first water stop blocks 17. When the door leaf 14 moves to the position of closing the water inlet end 41 of the circular culvert 4, one first water stop block 17 is used to fit with the first frame body 131 to seal between the door leaf 14 and the first frame body 131, and the other first water stop block 17 is used to fit with the second frame body 132 to seal between the door leaf 14 and the second frame body 132 to reduce the leakage on both sides of the door leaf 14 along the horizontal direction 2.

[0031] In a possible implementation, the integrated gate 1 for a circular culvert further includes a threshold 15, the threshold 15 is provided on the bottom wall 118 of the groove 116, and the threshold 15 cooperates with the bottom surface of the gate leaf 14.

[0032] In this embodiment, the threshold 15 is fixedly connected to the gate wall 112. When the gate leaf 14 moves to the position of closing the water inlet end 41 of the circular culvert 4, the threshold 15 fits against the bottom surface of the gate leaf 14 to reduce leakage at the bottom of the gate leaf 14.

[0033] In a possible implementation, the integrated gate 1 for a circular culvert further includes a second water stop block 18, the second water stop block 18 is provided at a position where the gate leaf 14 is close to the threshold 15, and the second water stop block 18 is used to seal the gate leaf 14 and the threshold 15.

[0034] In this embodiment, the second water stop block 18 is fixedly connected to the gate leaf 14, and the second water stop block 18 is used to seal the bottom of the gate leaf 14 and the threshold 15 to reduce leakage at the bottom of the gate leaf 14.

[0035] In a possible implementation, the integrated gate 1 for a circular culvert further includes a third water stop block 19, the third water stop block 19 is provided at the top of the gate leaf 14, and the third water stop block 19 extends from the gate leaf 14 above the water inlet end 41 of the circular culvert 4. The third water stop block 19 is used to fit against the culvert wall 111 to seal the gate leaf 14 and the culvert wall 111.

[0036] In this embodiment, the third water stop block 19 is fixedly connected to the gate leaf 14, and the third water stop block 19 is used to seal the top of the gate leaf 14 and the culvert wall 111 to reduce leakage at the top of the gate leaf 14.

The first water stop block 17, the second water stop block 18, and the third water stop block 19 are connected to each other. When the gate leaf 14 moves to the position of closing the water inlet end 41 of the circular culvert 4, the first water stop block 17, the second water stop block 18, and the third water stop block 19 seal the perimeter of the gate leaf 14, thereby reducing leakage of the gate.

[0038] In a possible implementation, the third water stop block 19 includes a spherical head portion 191 and a connecting portion 192 that are integrally connected. The connecting portion 192 is fixedly connected to the gate leaf 14, and the spherical head portion 191 protrudes from the connecting portion 192 toward the culvert wall 111.

[0039] In this embodiment, the spherical head 191 is a hollow sphere. The spherical head 191 has elasticity, so that the spherical head 191 elastically abuts against the culvert wall 111, thereby improving the sealing performance of the third water stop block 19 and reducing the leakage of the gate.

[0043] In this embodiment, the platform 12 protrudes from the top of the culvert wall 111. The hoist 16 is fixedly arranged on the platform 12, and the screw rod 161 extends from the position of the platform 12 to the gate leaf 14. Thus, the hoist 16 is drivingly connected to the gate leaf 14, and the hoist 16 drives the gate leaf 14 to move along the vertical direction 3.

[0044] In a possible implementation, the gate leaf 14 includes a lifting lug 141, a panel 142 and a beam slab 143.

The side beams 144 and the cross beams 145 are respectively fixedly connected to the panel 142 to improve the strength of the panel 142, thereby improving the strength of the gate leaf 14, reducing the deformation of the gate leaf 14 under the water pressure, improving the sealing performance of the gate leaf 14, and reducing the leakage of the gate.

[0046] The lifting lug 141 is fixedly connected to the cross beam 145 at the top. The lifting lug 141 is connected to the screw rod 161, and the screw rod 161 drives the gate leaf 14 to move through the lifting lug 141.
