Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0023] Example 1

[0024] The flood control and water storage intelligent gate described in this embodiment includes a wall 5, a flood discharge trough 1 communicating front and back is opened on the wall 5, a door frame 6 is fixed to the front side wall of the wall 5, and a door body 3 is arranged on the front side of the flood discharge trough 1, wherein the rear side wall of the wall 5 is in direct contact with the water flow, the flood discharge trough 1 is a rectangular structure, the door frame 6 is a rectangular frame, the wall 5 is made of concrete, and the door frame 6 and the door body 3 are made of high-strength materials such as cast iron;

[0025] The door body 3 is located in the door frame 6 and slides up and down with it. Figure 1 , Figure 2 and Figure 3 As shown, the left inner wall and the right inner wall of the door frame 6 are both provided with a slide groove, and the left and right walls of the door body 3 are both fixed with a slider 2, which is located in the corresponding slide groove and slides with it up and down. The slide groove and the slider 2 guide, limit and support the door body 3, thereby ensuring that the door body 3 can withstand the impact of water and can only move up and down; wherein the slide groove and the slider 2 are both "T"-shaped structures, and a first sealing gasket 16 for enhancing the sealing of the slider 2 and the slide groove is provided in the slide groove, and the sealing is improved by the first sealing gasket 16, thereby preventing water from flowing out from the gap between the slider 2 and the slide groove, thereby improving the water storage capacity of the reservoir, dam, etc.;

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a winch 7 is installed in the upper end of the door frame 6, and the left and right ends of the top of the door body 3 are connected to a steel rope 4 with one end fixed thereto, and the other ends of the two steel ropes 4 are wound on the winch 7 (the winch 7 and the steel rope 4 in this paragraph constitute the first driving assembly for continuing to drive the door body 3 to move up and down when the first driving assembly is damaged. In actual application, the winch 7 can also have two parts, and the two steel ropes 4 are respectively wound on one of the winches 7). In this embodiment, the steel rope 4 is reeled in or released by starting the winch 7, thereby opening or blocking the flood discharge chute 1, so that the flood in the reservoir or dam flows out of the flood discharge chute 1 or remains in the reservoir for storage, and the flood discharge flow of the flood discharge chute 1 can be controlled by controlling the opening degree of the door body 3; wherein the winch 7 is a prior art, which is a light and small lifting equipment that uses a drum to wind a wire rope or chain to lift or pull a heavy object, and is mainly composed of a motor, a reducer, a brake, a drum, etc. The drum is selected to be a long drum, such as Figure 1 As shown;

[0027] A radar water level meter 14 for detecting the water level is installed on the rear side wall of the wall 5, and a plurality of flow meters 13 for detecting the water flow velocity are installed on the wall of the flood discharge channel 1. The radar water level meter 14 and the flow meter 13 are convenient for the staff to understand the water level in the reservoir and the flow velocity during flood discharge, so as to adjust the door body 3 to a suitable opening according to the water level and flow velocity of the flood, so as to avoid the huge pressure brought to the downstream by direct full-open flood discharge; wherein the radar water level meter 14 and the flow meter 13 are both prior arts, and the measurement principle of the radar water level meter 14 is to transmit radar pulses from the radar water level sensor antenna , the antenna receives the pulse reflected from the water surface and records the time T. Since the propagation speed C of the electromagnetic wave is a constant, the distance D to the water surface is obtained. The flow meter 13 adopts a flow meter in contact with water, such as a Doppler ultrasonic flow meter. Its measurement principle is: the ultrasonic transducer emits a beam of ultrasonic waves of a fixed frequency, which is reflected after encountering particles and tiny bubbles in the water and is received by another ultrasonic transducer. By measuring the frequency difference between the emission and reception (Doppler effect frequency difference), the moving speed of the particles can be calculated (the suspended particles are very small and are approximately the same as the water flow speed);

[0028] A displacement sensor 10 for detecting the displacement distance of the door body 3 is installed on the top of the door body 3, and a multi-stage hydraulic cylinder 8 is installed on the inner top of the door frame 6. A controller 9 is vertically arranged below the multi-stage hydraulic cylinder 8. One end of the controller 9 is connected to the power output end of the multi-stage hydraulic cylinder 8, and the other end is installed in the door body 3 and threadedly matched with it (the multi-stage hydraulic cylinder 8 and the controller 9 in this paragraph constitute the second drive component for driving the door body 3 to move up and down. In actual application, the first drive component can also adopt a multi-stage hydraulic cylinder to directly drive the door body 3 to move up and down). In this embodiment, the displacement distance of the door body 3 is detected by the displacement sensor 10 When the multi-stage hydraulic cylinder 8 is started and the displacement sensor 10 detects that the door body 3 has not moved, the winch 7 may be damaged, resulting in the door body 3 being unable to close or open the flood discharge chute 1, thereby affecting the flood discharge and water storage capacity of the reservoir or dam. However, the staff can start the multi-stage hydraulic cylinder 8 to drive the door body 3 to move upward, thereby ensuring that the door body 3 can continue to play the role of flood discharge; wherein the multi-stage hydraulic cylinder 8 is a prior art, which is composed of a two-stage or multi-stage piston cylinder set, mainly composed of a cylinder head, a cylinder barrel, a sleeve, a piston rod and other parts, and its working stroke can be very long, and can be shortened when not working, and is suitable for occasions where the installation space is limited and the stroke is required to be very long;

[0029] It also includes a controller 9, and the radar water level meter 14, the flow meter 13, the displacement sensor 10, the multi-stage hydraulic cylinder 8 and the winch 7 are all electrically connected to the controller 9. The controller 9 receives signals from the radar water level meter 14, the flow meter 13 and the displacement sensor 10, and combines the remote control of the staff to realize intelligent control of the opening and closing of the multi-stage hydraulic cylinder 8 and the winch 7, thereby improving the degree of intelligence. In practice, there are also signal receiving and transmission equipment for cooperating with the remote control of the staff, and the mains electricity is used to power the entire device;

[0030] A second elastic sealing gasket 12 is fixed to the inner bottom of the door frame 6, and a conical groove is opened at one end of the inner bottom of the door frame 6 directly below the second sealing gasket 12. A sealing block 11 for pressing the middle part of the second sealing gasket 12 into the conical groove is fixed to the bottom of the door body 3. The gravity of the door body 3 is used to make the sealing block 11 press the middle part of the second sealing gasket 12 into the conical groove, thereby achieving the sealing between the door body 3 and the inner bottom of the door frame 6, and then cooperating with the slider 2 and the first sealing gasket 16 to achieve the overall sealing of the door body 3 and the door frame 6 to prevent water in the reservoir from flowing out. At the same time, compared with the traditional sealing method, this sealing method does not need to worry about the accumulation of mud and sand affecting the sealing performance. Figure 1 and Figure 2 As shown, the second sealing gasket 12 is in a triangular pyramid structure, and is made of rubber. The lower groove wall of the slide groove is flush with the inner bottom of the door frame 6, and both left and right ends of the second sealing gasket 12 extend into the corresponding slide groove, thereby further improving the sealing performance;

[0031] The lower wall of the spillway 1 is flush with the top of the second sealing pad 12. Figure 1 , Figure 2 and Figure 4 As shown, it is convenient for the staff to calculate the flood discharge of the flood spillway 1 through the cross-sectional area of ​​the flood peak, and the cross-sectional area is the product of the length of the flood spillway 1 and the opening height of the door body 3 (or the height of the flood spillway 1 itself).

[0032] When this embodiment is in use, first the displacement sensor 10 detects the height of the door body 3, the flow meter 13 detects the speed of the flood peak flowing through the flood discharge chute 1 in real time, and then combined with the radar water level meter 14, the height of the door body 3 is intelligently adjusted (for example, after the door body 3 is raised, the water level in the reservoir still increases rapidly, then the door body 3 is raised; for example, if the flood discharge caused by the current height of the door body 3 is greater than the flood resistance limit that the downstream can bear, then the door body 3 is lowered, etc.), and then when the winch 7 is started, and the displacement sensor 10 does not detect the displacement distance of the door body 3, the controller 9 controls the controller 9 to start and drive the door body 3 to rise. At this time, the door body 3 can still be opened normally to discharge flood.

[0033] Example 2

[0034] This embodiment further illustrates the technology. A vibration sensor 15 is installed on the front side wall of the door body 3. The vibration sensor 15 senses the overall vibration degree of the door body 3, so as to understand the structural safety of the door body 3 to a certain extent, so as to avoid damage to the door body 3.
