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.

[0020] The utility model provides a technical solution, a leakage-proof structure for a sluice pump station, please refer to Figure 1 , Figure 3 , Figure 4 , comprising a sluice bottom plate 1, a pier 2 is installed on the sluice bottom plate 1, a gate 3 is arranged in the pier 2, an elastic unloading water bag 4 is arranged on the bottom side of the gate 3, the upper end of the elastic unloading water bag 4 is connected with a pressure increasing and reducing pipe 5, a pressure increasing and reducing valve 7 is installed on the pressure increasing and reducing pipe 5, a pressure monitoring device 6 is installed on the bottom end of the pressure increasing and reducing pipe 5, a magnetic bolt 13 is installed on the upper side of the elastic unloading water bag 4, a magnetic hole 12 is opened on the bottom side of the gate 3, the elastic unloading water bag 4 is magnetically plugged with the magnetic hole 12 at the bottom of the gate 3 through the magnetic bolt 13, and the connection stability of the elastic unloading water bag 4 is strengthened. While qualitatively determining the pressure, it ensures that the elastic unloading water bag 4 can work normally when the gate 3 is opened and closed, and it is convenient to replace the elastic unloading water bag 4 later while achieving positioning. The pressure increasing and reducing valve 7 is fixedly installed on the top of the gate 3, and a through groove 11 is vertically opened in the gate 3. The pressure increasing and reducing pipe 5 vertically penetrates the through groove 11, and the pressure monitoring device 6 will reduce the pressure of the elastic unloading water bag 4 through the pressure increasing and reducing valve 7 according to the strong pressure on the elastic unloading water bag 4, so as to maintain the internal pressure of the elastic unloading water bag 4 stable, reduce the risk of the water in the elastic unloading water bag 4 being unable to be discharged and bursting the elastic unloading water bag 4, and improve the service life of the elastic unloading water bag 4;

[0021] See also Figure 2 , Figure 4A limiting groove 8 is provided on the inner side of the upper end of the gate pier 2, and a limiting bolt 9 is installed in the limiting groove 8. A buffer spring 10 with a damping structure is sleeved around the limiting bolt 9. A pressing ring 14 is installed on both sides of the upper end of the gate 3. The pressing ring 14 is slidably sleeved with the limiting bolt 9, and the bottom side of the pressing ring 14 is pressed and contacted with the buffer spring 10. The other end of the buffer spring 10 is pressed and contacted with the bottom side surface of the limiting groove 8, so that the gravity when the gate 3 is closed can be buffered to a certain extent. The installation position of the additional pressing ring 14 corresponds to the buffer spring 10. When the gate is in the lowered state, the pressing ring 14 will press down the lower buffer spring 10, thereby elastically buffering the gate 3 as a whole, thereby achieving a buffering and shock-absorbing effect.

[0022] In the utility model, a gate pier 2 is installed on the bottom plate 1 of the sluice, a gate 3 is arranged in the gate pier 2, and the gate 3 is opened and closed up and down, and an elastic unloading water bag 4 is arranged at the bottom of the gate 3, and a magnetic bolt 13 is installed on the upper side of the elastic unloading water bag 4, and a magnetic hole 12 is opened at the bottom of the gate 3. The elastic unloading water bag 4 is magnetically connected with the magnetic hole 12 through the magnetic bolt 13, while strengthening the connection stability of the elastic unloading water bag 4, ensuring that the elastic unloading water bag 4 can work normally when the gate 3 is opened and closed, achieving positioning and facilitating the replacement of the elastic unloading water bag 4 in the later stage;

[0023] The upper side of the elastic unloading water bag 4 is connected with a pressure increasing and reducing pipe 5, which passes through a vertical through groove 11 in the gate 3. A pressure increasing and reducing valve 7 is installed on the pressure increasing and reducing pipe 5, which is fixedly installed on the top of the gate 3, and a pressure monitoring device 6 is also installed on the top of the pressure increasing and reducing pipe 5. When the gate 3 is opened and closed, the water discharge of the elastic unloading water bag 4 relieves the pressure of the gate 3 impacting the sluice bottom plate 1 during operation, thereby reducing the risk of the gate 3 hitting the sluice bottom plate 1 and causing cracks in the sluice bottom plate 1. In order to avoid damage to the elastic unloading water bag 4 when the gate 3 is squeezed when the gate 3 is closed, the pressure increasing and reducing valve 7 and the pressure monitoring device 6 are installed for the elastic unloading water bag 4. When the gate 3 is closed, the pressure monitoring device 6 will reduce the pressure of the elastic unloading water bag 4 through the pressure increasing and reducing valve 7 according to the strong pressure on the elastic unloading water bag 4, so as to maintain the internal pressure of the elastic unloading water bag 4 stable, reduce the risk of the water in the elastic unloading water bag 4 being unable to be discharged and bursting the elastic unloading water bag 4, and improve the service life of the elastic unloading water bag 4;

[0024] A pressure collar 14 is installed on both sides of the upper end of the gate 3. The pressure collar 14 can be plugged into a limiting groove 8 opened in the inner wall of the upper end of the gate pier 2, and a limiting bolt 9 is arranged in the limiting groove 8. The limiting bolt 9 can be sleeved with the pressure collar 14. After the limiting bolt 9 is sleeved with the pressure collar 14, the pressure collar 14 and the buffer spring 10 sleeved on the side of the limiting bolt 9 are pressed against each other, thereby providing a certain degree of buffering effect on the gravity when the gate 3 is closed.
