DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0020] like Figures 1 to 9 As shown, the present invention provides a flood control gate for a water conservancy project, comprising two cement foundations 1 for gates, on which an anti-blocking mechanism and a cleaning mechanism are arranged, the anti-blocking mechanism comprises a door body 2 arranged on a side where the two cement foundations 1 are close to each other, an electric gate 201 is slidably installed on the front inner wall of the door body 2, and anti-blocking components are respectively arranged on the tops of the cement foundations 1 for gates, the anti-blocking components comprise a fixed block 3 fixedly installed on the tops of the cement foundations 1 for gates, a rotating rod 4 is rotatably installed on one side where the two fixing blocks 3 are close to each other, one end of the rotating rod 4 extends out of the corresponding fixing block 3, a connecting rod 6 is fixedly sleeved on the outer wall of the rotating rod 4, a connecting rod 2 7 is hingedly installed on the front of the connecting rod 6, and a connecting rod 2 7 is rotatably installed on the back of the connecting rod 2 7. A cleaning strip 9 is installed, and a sliding frame 8 is fixedly installed on the front of the door body 2. The two round rods on the sliding frame 8 both penetrate the cleaning strip 9 and are slidably connected to the cleaning strip 9. Tooth grooves 2011 are respectively opened on both sides of the electric gate 201. Gears 2 10 are rotatably installed on the inner walls of both sides of the door body 2, and the two gears 2 10 are respectively meshed with the adjacent tooth grooves 2011. Gears 1 5 are fixedly sleeved on the outer walls of the two rotating rods 1 4, and the two gears 1 5 are respectively meshed with the corresponding gears 2 10. Two filters 11 are arranged on the front of the door body 2, and the front of one filter 11 is in contact with the back of the cleaning strip 9, and the other filter 11 is fixedly connected to the front of the door body 2 by bolts, and the two filters 11 are slidably connected on the side close to each other.

[0021] By setting up an anti-blocking component, when the electric gate 201 is raised or lowered, the meshing transmission between the tooth groove 2011 and the gear 2 10, and the mutual engagement between the gear 1 5 and the gear 2 10 drive the rotating rod 1 4 and the connecting rod mechanism to move, thereby driving the cleaning strip 9 to slide on the sliding frame 8, and efficiently cleaning the filter 11. One of the two filter screens 11 is tightly fitted with the cleaning strip 9, and the other is fixedly connected to the door body 2 by bolts. The two are slidably connected to each other, which not only ensures the filtering effect, but also facilitates the cleaning operation of the cleaning strip 9. When the water flow carries impurities through the filter screen 11, the impurities are effectively intercepted, and the reciprocating motion of the cleaning strip 9 can timely remove the impurities attached to the filter screen 11 to prevent the filter screen 11 from being blocked, thereby ensuring unimpeded water flow.

[0022] The electric gate 201 is driven to rise and fall by a motor, and the meshing transmission between the tooth groove 2011 and the gear 2 10 and the combined design of the connecting rod mechanism are utilized to realize the automatic reciprocating motion of the cleaning strip 9 on the sliding frame 8, which not only effectively removes impurities attached to the filter screen 11 and prevents the filter screen 11 from being blocked, but also greatly improves the efficiency and automation of the cleaning operation, eliminates the need for frequent manual intervention, reduces labor intensity, and also reduces the potential risks caused by the blockage of the filter screen 11, ensuring unimpeded water flow.

[0023] like Figures 7 to 9 As shown, the cleaning mechanism includes a rotating rod 13 fixedly mounted on the top inner wall of the door body 2, a rotating wheel 14 is rotatably sleeved on the outer wall of the rotating rod 13, a collecting frame 12 is slidably mounted on the bottom inner wall of the door body 2, a metal braided rope 15 is fixedly mounted on the top of the collecting frame 12, the other end of the metal braided rope 15 is fixedly connected to the bottom back of the electric gate 201, and the metal braided rope 15 is slidably connected to the rotating wheel 14.

[0024] The metal braided rope 15 is used as a connecting component to connect the electric gate 201 and the collection frame 12, thereby ensuring the synchronous movement between the electric gate 201 and the collection frame 12. Moreover, through the sliding connection between the metal braided rope 15 and the rotating wheel 14, the reverse movement of the two in the vertical direction is realized, that is, when the electric gate 201 rises, the metal braided rope 15 pulls the collection frame 12 down; conversely, when the electric gate 201 descends, the collection frame 12 rises accordingly.

[0025] By setting up a linkage mechanism between the collecting frame 12 and the electric gate 201, and utilizing the sliding connection between the metal braided rope 15 and the rotating wheel 14, the electric gate 201 and the collecting frame 12 can achieve reverse movement in the vertical direction. When the electric gate 201 rises, the collecting frame 12 descends, thereby effectively collecting the garbage that has settled after passing through the filter screen 11. This not only simplifies the garbage collection process, but also improves the efficiency of garbage disposal. The staff only needs to clean up the garbage in the collecting frame 12 when it rises, thereby greatly saving time and labor costs. At the same time, by setting up a cleaning rack 16, it further prevents missed garbage from entering the downstream water flow, thereby protecting the safety of the water environment.

[0026] like Fig. 9 As shown, a cleaning rack 16 is slidably installed on the back inner wall of the door body 2. The cleaning rack 16 and the electric gate 201 are respectively located on the front and back of the collecting frame 12. The cleaning rack 16 is composed of two filter plates of different sizes. The height value of the filter plate close to the collecting frame 12 is lower than the height value of the filter plate far away from the collecting frame 12.

[0027] By setting up a cleaning rack 16 composed of two filter plates of different sizes, the filter plate close to the collecting frame 12 is lower in height, while the filter plate away from the collecting frame 12 is higher in height, so that a certain flow rate difference and pressure difference can be formed when the water flows through, which helps to better remove impurities attached to the filter plates.

[0028] like Figures 1 to 9 As shown, a method for flood control gates in water conservancy projects, the specific steps of the method include: S1, early warning and monitoring system construction: build an early warning system for disasters such as floods and rainstorms to ensure that water and rainfall information can be obtained in real time; S2, formulate and implement dispatching plans: flexibly adjust the operation status of the sluice gates according to real-time conditions such as water level and rainfall to meet diversified needs such as flood control, drainage, and water supply; S3, Emergency Dispatch and Safety Assurance: Establish and improve the emergency dispatch mechanism for sluice gates to ensure rapid response in emergency situations and take effective measures to ensure the safety of sluice gates.

[0029] A system of flood control gates for water conservancy projects, the specific contents of the system include: Data acquisition module: Use water level sensors to monitor the changes in upstream and downstream water levels in real time to provide a basis for gate scheduling; use flow sensors to measure parameters such as water flow velocity and flow to evaluate the discharge capacity of the river channel; Control module: automatically adjusts the gate opening according to real-time data of water level and flow, and realizes intelligent scheduling of flood control, drainage, irrigation and other functions; Monitoring module: processes and analyzes the collected data, generates various reports and charts, and provides decision support for managers; Cleaning protection module: Reduces foreign matter in the water flow from entering the downstream water body.

[0030] The monitoring module is also equipped with a remote control interface of the monitoring center, enabling managers to remotely control the gates.

[0031] The working principle and use process of the present invention: When the entire cleaning and collection process needs to be started, the motor inside the door body 2 is started first. The motor provides power for the entire system to ensure that the subsequent components can operate in an orderly and efficient manner. The motor drives the electric gate 201 to rise slowly, and the tooth grooves 2011 on both sides of the electric gate 201 are precisely meshed with the gears 10 installed on the inner walls of both sides of the door body 2. The gears 10 start to rotate under the drive of the electric gate 201, and the gears 10 are meshed with the gears 5 fixed on the outer wall of the rotating rod 4, thereby driving the gears 5 and the rotating rod 4 to rotate synchronously, and the rotation of the rotating rod 4 The rotation drives the connecting rod 1 6 to perform circular motion, and the connecting rod 1 6 is connected to the connecting rod 2 7 through the hinge point, so that the connecting rod 2 7 is moved under the drive of the connecting rod 1 6, and the movement of the connecting rod 2 7 further drives the cleaning strip 9 to reciprocate back and forth on the sliding frame 8. The back and forth movement of the cleaning strip 9 effectively removes impurities attached to the outer wall of the filter screen 11 to prevent the filter screen 11 from being blocked. At the same time, the rise of the electric gate 201 is also linked with the collection frame 12 through the metal braided rope 15. Under the guidance of the rotating wheel 14, when the electric gate 201 rises, the collection frame 12 falls accordingly; On the contrary, when the electric gate 201 descends, the collecting frame 12 rises, and when water flows through the filter 11, most of the garbage is effectively intercepted by the filter 11. A small amount of garbage will be deposited in the space formed by the electric gate 201 and the cleaning rack 16 after passing through the filter 11. When the collecting frame 12 rises to the top, the staff can easily clean up the garbage therein. After cleaning, the collecting frame 12 will descend again when the electric gate 201 descends next time, ready to meet a new garbage collection task. By setting up the cleaning rack 16, the last missed garbage can enter the cleaning rack 16. The setting of the cleaning rack 16 effectively prevents garbage from entering the downstream water flow, further protecting the safety of the water environment.
