The side wall of the gate slot body 1 is also provided with a groove 102 adjacent to the upstream direction of the first wall surface 101, and the rotating body 2 is rotatably installed in the groove 102. The rotating body 2 has a second wall surface 201, and the second wall surface 201 is provided with a guide rail 3. When the rotating body 2 is in the first rotation position, the second wall surface 201 is connected with the first wall surface 101 to form a complete wall surface structure, that is, the wall surface structure disclosed in the patent with application number 202410031086.8, which is conducive to avoiding cavitation, reducing head loss, and reducing the vibration of the gate 20. When the rotating body 2 is in the second rotation position, the upstream side of the second wall surface 201 moves into the groove 102 to form a suitable space for the gate 20 to be lowered and installed.

[0031] As a preferred example, the rotating body 2 is also provided with a limit plate 4, which is installed on the upstream side of the second wall surface 201 of the rotating body 2. After the rotating body 2 rotates from the second rotation position to the first rotation position, the limit plate 4 contacts the upstream side wall surface of the groove 102 to form a limit.

[0032] As a preferred example, the door slot structure also includes a locking mechanism for locking or unlocking the rotating body 2 when the rotating body 2 is in the first rotation position. The function of the locking mechanism is to lock the rotating body 2 to prevent it from rotating in the opposite direction due to the action of the side of the gate 20. Specifically, the locking mechanism includes a lock shaft seat 5, a lock shaft 6 and a plug plate 8. The lock shaft seat 5 is fixedly mounted on the top of the door slot, and the lock shaft 6 is slidably mounted in the sliding hole of the lock shaft seat 5 to achieve the purpose of horizontal linear sliding. A plug 7 is provided at the end of the lock shaft 6. The plug plate 8 is fixedly mounted on the top end surface of the rotating body 2, and it has a socket 801. When the rotating body 2 rotates to the first rotation position, the plug 7 and the socket 801 are aligned, and the lock shaft 6 is moved to insert the plug 7 into the socket 801 to lock the rotating body 2 to prevent it from rotating.

[0033] As a preferred example, the rotating body 2 includes a metal frame 10 which also serves as a shell and a rotating shaft 9. The rotating shaft 9 penetrates the metal frame 10 and is fixedly installed. A flange 19 is fixedly installed on the rotating shaft 9, and the flange 19 is fixed to both ends of the metal frame 10 by bolts. A bearing groove is provided at the bottom of the groove 102 of the door groove body 1 to install a bearing. The bottom end of the rotating shaft 9 is connected to the bearing in the bearing groove.

[0034] As a preferred example, the metal skeleton 10 includes an arc-shaped enclosure plate 11, a wall panel 12 and a rib plate 13. The arc-shaped enclosure plate 11 is fixedly mounted on the outer side of the wall panel 12 to enclose a cavity. The rib plates 13 are equidistantly distributed from one end of the cavity to the other end and fixedly connect the arc-shaped enclosure plate 11 and the wall panel 12, and the wall panel 12 constitutes a second wall surface 201. The rotating shaft 9 passes through the rib plate 13 and is fixedly connected. Obviously, the shape of the groove 102 matches the shape of the arc-shaped enclosure plate 11. The rib plate 13 at the bottom of the rotating body 2 can also be provided with a circle of bottom water stop, which is used to form a water stop seal with the bottom surface of the groove 102 to prevent dirt from entering the bearing.

[0035] As a preferred example, in order to improve the strength of the rotating body 2, the rotating body 2 further includes a concrete filling body 14 filled in the metal frame 10. Except for the rib plate 13 at the top, the other rib plates 13 are provided with through holes 1301. When pouring concrete, the concrete flows from the top to the bottom through the through holes 1301 in sequence and gradually fills the cavity.

[0036] As a preferred example, the driving mechanism includes a mounting frame 15, a driving gear 16, a driven gear 17 and a handwheel 18. The mounting frame 15 is mounted on the top surface of the door slot body 1. Specifically, a base is embedded in the top surface of the door slot body 1, and the mounting frame 15 is mounted on the base by bolts. A bearing is fixedly mounted on the mounting seat, and the top of the rotating shaft 9 is connected to the bearing on the mounting seat. The driving gear 16 is rotatably mounted on the mounting frame 15, the handwheel 18 is coaxially mounted on the gear shaft of the driving gear 16, and the driven gear 17 is mounted on the top of the rotating shaft 9 and meshes with the driving gear 16. The rotating body 2 can be driven to rotate around the axis by turning the handwheel 18. That is to say, during operation, it is necessary to manually stand on the door slot body 1 and operate the handwheel 18. The gear ratio of the driving gear 16 to the driven gear 17 is 1:5-1:10, so as to better drive the rotating body 2 to rotate.

[0037] The utility model also discloses a gate device, including a gate slot body 1 and a gate 20 installed in the gate slot body 1, the gate 20 is provided with installation bevels and installation planes located on the downstream side of the installation bevels on both sides, the installation bevels are provided with water-stopping structures, and the installation planes are provided with obliquely installed elastic anti-wheel devices 21; the gate slot body 1 has the above-mentioned gate slot installation structure. After the gate 20 is installed, the elastic anti-wheel device 21 is matched with the guide rail 3. Before installing the gate 20, the rotating body 2 is first rotated to the second rotation position, at which time the downstream side of the rotating body 2 is rotated into the groove 102, and a certain installation space is formed on the downstream side of the groove 102, at which time the gate 20 can be lowered, and after the gate 20 is lowered, the rotating body 2 returns to the first rotation position, the guide rail 3 is matched with the elastic anti-wheel device 21, and the gate 20 is installed. During operation, debris in the water body will also accumulate at the location of the elastic anti-wheel device 21, so the rotating body 2 can also be driven to rotate to the second rotation position, so as to facilitate cleaning of the debris here to avoid normal use of the gate 20.

[0038] As a preferred example, the elastic anti-wheel device 21 includes a base 22, a cross frame 23, a roller 25, a spring 26 and a limit seat. The cross frame 23 is rotatably mounted on the base 22 via a central pivot 24, one end of the cross frame 23 is mounted with the roller 25, and the other end is mounted with an abutment plate 28; the limit seat is fixedly mounted on the base 22 on the side where the abutment plate 28 is located, and the spring 26 is abutted between the top plate 27 of the limit seat and the abutment plate 28. When the roller 25 swings down, the other end of the cross frame 23 tilts up and compresses the spring 26. The elastic anti-wheel device 21 has a simpler structure and lower cost.
