[0002] Hydraulic gates are opening and closing devices used to regulate water flow in water conservancy projects. They are widely used in rivers, channels, reservoirs, lakes and coastal projects, playing an important role in regulating water levels, controlling flow, preventing backflow and discharging floods and waterlogging. As an important part of water conservancy facilities, hydraulic gates play a vital role in promoting the rational use of water resources, protecting the water ecological environment, and preventing water and drought disasters.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-6 The present invention provides a technical solution: a water conservancy automatic control gate with a counterweight box, comprising a cross bar 1, a gate panel 5 is connected to the right end of the cross bar 1, and the cross bar 1 supports the gate panel 5 in the flood season or when the canal needs to collect water. The left end of the cross bar 1 is connected to a support rod 6, and the bottom of the support rod 6 is connected to a rotating block 8. The bottom of the rotating block 8 is connected to a vertical support rod 9 through an axle rod. The vertical support rod 9 provides support force to the support rod 6 and realizes the rotation of the cross bar 1 through the rotating block 8 to lift and lower the gate panel 5. The left end of the support rod 6 is connected to a triangular block 12, and a square groove 7 is opened on the support rod 6, and a filter assembly 4 is installed in the square groove 7 to filter the inflowing water when releasing water, and support columns 11 are installed at the front and rear ends of the support rod 6;

[0030] A limit box 2, a counterweight box 3 is movably inserted on the top of the limit box 2, and the inside of the counterweight box 3 can be filled with liquid such as water, or other heavy objects, which increases the stability of the device and also increases the weight of the counterweight box 3. When moving downward, the gate panel 5 is lifted, and the outer wall of the counterweight box 3 is connected to the end of the triangular block 12, and a vertical movable groove adapted to the size of the triangular block 12 is opened on the limit box 2, and limit vertical plates 14 are set on the front and rear outer walls of the limit box 2, and two groups of water troughs 13 with the same structure are opened at the bottom of the limit box 2;

When collecting water, the gate panel 5 blocks the water flow (because it does not require particularly good sealing, some water will slowly enter the canal during the water blocking process of the gate panel 5) to accumulate water needed for irrigation. When the water needs to be discharged into the canal, the counterweight box 3 can be filled with water. When the weight in the counterweight box 3 reaches a certain level, the triangular block 12 will be pressed down (because the counterweight box 3 has a certain movable space in the limit box 2, so this kind of arc movement with a small angle can be achieved), thereby lifting the gate panel 5 to realize the operation of draining water from the canal.

[0032] The counterweight box 3 has a counterweight groove 31 on the top thereof, a vertical limit bar 32 is provided on the inner wall of the counterweight groove 31, and a waterproof component 15 is movably installed on the limit bar 32, and a connecting plate 33 is installed on the outer wall of the counterweight box 3, and the connecting plate 33 is connected to the end of the triangular block 12 through an axle rod;
