[0012] (III) Beneficial effects
[0013] Compared with the prior art, the utility model provides a river gate for water conservancy projects, which has the following beneficial effects:
[0014] 1. The river gate used in this water conservancy project, when the water level is high and the gate needs to be opened, the linear cylinder is started, and then the water enters the interior of the flow channel through the opening, and finally discharged through the opening. This setting can reduce the water level when the gate is opened too high. When the gate is opened directly, the water flow suddenly increases, which is easy to cause impact on the original riverbed, and easily cause a surge in water volume downstream, overflowing the river bank, causing flooding, that is, facing the risk of overflowing the bank. By adding a high-level drainage component, this device can drain the water level to below the high-level drainage component first, and then open it, effectively reducing the occurrence of the above problems.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-4 A river gate for a water conservancy project comprises an external frame 1, a cross bar 2 is transversely installed inside the external frame 1, a threaded sleeve 6 is fixedly installed at the bottom of the cross bar 2, a screw rod 5 is threadedly connected to the inner thread of the threaded sleeve 6, a valve plate 4 is rotatably installed at the lower end of the screw rod 5, a high-position drainage component is arranged on the valve plate 4, an opening 15 is opened at the bottom of the side of the valve plate 4 away from the water inlet of the high-position drainage component, a motor 9 is fixedly installed on the top of the external frame 1, a telescopic component is arranged on the upper end of the screw rod 5, and one end of the telescopic component is connected to the output end of the motor 9.
[0022] Furthermore, the telescopic assembly includes a rotating sleeve rod 8 and a rectangular rod 7. A cavity with a rectangular cross section is opened inside the rotating sleeve rod 8. The upper end of the rectangular rod 7 is inserted into the cavity of the rotating sleeve rod 8. The lower end of the rectangular rod 7 is fixedly connected to the upper end of the screw rod 5. The upper end of the rotating sleeve rod 8 is rotatably connected to the output shaft of the motor 9. When the motor 9 is started, the valve plate 4 will move up and down due to the threaded connection between the threaded sleeve 6 and the screw rod 5. At the same time, the rectangular rod 7 will move up and down inside the rotating sleeve rod 8. The cross-section of the internal cavity of the rotating sleeve rod 8 is rectangular. Therefore, when the rotating sleeve rod 8 rotates, it will drive the rectangular rod 7 to rotate together.
[0023] Furthermore, two corresponding guide rods 10 are fixedly installed on the top of the valve plate 4, and a circular hole is opened at the position of the cross bar 2 corresponding to the guide rod 10. The guide rod 10 passes through the circular hole. The guide rod 10 and the circular hole can provide guidance for the valve plate 4 to move up and down.
[0024] Furthermore, a side groove 3 is provided on the inner wall of the outer frame 1 corresponding to the position of the valve plate 4, and both sides of the valve plate 4 are slidably engaged in the inside of the side groove 3. By adding the side groove 3, guidance can be further provided for the up and down movement of the valve plate 4.
[0025] Furthermore, the high-position drainage assembly includes a linear cylinder 11 and a rectangular stopper 13. An opening 12 is provided on the side of the external frame 1 facing away from the opening 2 15. An internal groove 14 is provided on the top inner wall of the opening 12. The linear cylinder 11 is fixedly mounted on the top of the valve plate 4, and the rectangular stopper 13 is movably mounted inside the internal groove 14. The top of the rectangular stopper 13 is fixedly connected to the output shaft of the linear cylinder 11.
[0026] Furthermore, the opening 12 is connected to the opening 2 15 through the flow channel 16. When in use, the side of the opening 12 corresponds to the side of the high water level. When the water level is high and the gate needs to be opened, the linear cylinder 11 is started, and then the water enters the interior of the flow channel 16 through the opening 12, and is finally discharged through the opening 2 15. This arrangement can reduce the risk of the gate being opened when the water level is too high. When the gate is opened directly, the water flow suddenly increases, which can easily impact the original riverbed and cause a surge in water volume downstream, overflowing the river bank and causing a flood. In other words, the device faces the risk of overflowing the bank. By adding a high-level drainage component, the water level can be discharged to below the high-level drainage component first. During actual use, the height of the high-level drainage component is set according to the water level that may cause overflowing the bank, and then opened 47, which effectively reduces the occurrence of the above problems.
[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
