Description

Technical Field

[0001] The present application relates to the technical field of gate structures, and in particular to a drainage gate for preventing floods in areas. Background Art

[0002] A drainage gate is a hydraulic structure built in a river or canal that uses a gate to control water flow and adjust the water level. When the gate is closed, it can block floods, block tides, or raise the upstream water level. When a flood disaster occurs, the gate can be opened to release water to prevent farmland from suffering from flood disasters. However, in actual use, the existing gates are eroded by water for a long time, and under the huge pressure of water, the two sides of the gate in contact with the abutment are severely worn during the opening and closing process, which causes the gate to shift along the direction of the water pressure, causing the screw on it to deflect. When the gate is opened and closed to transmit torque, it is very easy to cause damage to the screw or power equipment due to the deflection of the screw, and even the screw may break, which poses a great safety hazard and has poor stability and reliability.

[0003] Therefore, there is an urgent need for a drainage gate structure to solve the defects of the above-mentioned existing drainage gates in actual use. Summary of the invention

[0004] The present application proposes a drainage gate for preventing floods in flood-prone areas, which has the advantage of being able to compensate for the wear on both sides of the gate and effectively prevent it from shifting in the direction of water pressure, thereby causing the screw thereon to deflect. It is used to solve the problem that the existing gate is eroded by water for a long time during actual use, and under the huge pressure of water pressure, it causes severe wear on both sides of the gate in contact with the pillar during the opening and closing process, thereby causing the gate to shift in the direction of water pressure, causing the screw thereon to deflect, and when the gate is opened and closed to transmit torque, it is very easy to cause damage to the gate or power equipment due to the deflection of the screw, and even cause the screw to break.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a drainage gate for preventing floods in areas, including a gate, a group of slide grooves are opened on both side end faces of the gate, and at the same time, a screw assembly is movably sleeved inside the top of the gate, and a group of compensation components are respectively provided on both sides of the back of the gate, and the compensation components include a support group frame fixedly installed on the pillar, a power component is fixedly installed on one side of the top of the support group frame, and the power shaft of the power component is fixedly installed with a linkage block whose side end is movably connected to the side of the gate, and a slot is opened on the other side end of the linkage block, and the top of the inner wall of the slot is in contact with a sphere movably sleeved on the support group frame.

[0006] Furthermore, a first gap is provided between the side of the gate and the side of the support assembly frame, so that when wear occurs on both sides of the gate, the gate can move along the direction of the water pressure under the action of water pressure, and form a feedback system to control the downward movement distance of the linkage block driven by the power component.

[0007] Furthermore, the screw rod assembly includes a threaded connecting rod, and a ring groove is provided at the bottom of the outer surface of the threaded connecting rod, and the ring groove is movably engaged with a cylindrical groove provided inside the top end of the gate.

[0008] Furthermore, a second gap is provided between the outer surface of the threaded connecting rod and the inner wall of the cylindrical groove.

[0009] Furthermore, the threaded connecting rod is internally movably sleeved with a trigger rod whose bottom end extends to the bottom of the threaded connecting rod, and a cone is fixedly installed at the bottom end of the trigger rod, and the trigger rod and the threaded connecting rod are transmission connected through an elastic member movably sleeved on the bottom of the outer surface of the trigger rod.

[0010] Furthermore, the feedback system includes a first induction ring fixedly sleeved on the bottom of the inner wall of the threaded connecting rod and a second induction ring fixedly sleeved on the bottom of the outer surface of the trigger rod, and the second induction ring is initially located below the first induction ring. At the same time, the first induction ring, the second induction ring and the control system of the power component are electrically connected.

[0011] Furthermore, the top end of the linkage block extends to the top of the gate, and the top end of the linkage block is always located above the top end of the gate, while the bottom end of the linkage block is located above the bottom end of the gate.

[0012] The present invention application has the following technical effects: The present application provides a drainage gate for preventing floods in areas. With respect to the arrangement of a screw assembly and a compensating component, when the gate moves along the water pressure direction due to wear on both sides, the trigger rod and the second induction ring thereon can be forced to move upward accordingly, and then the wear state on both sides of the gate can be judged according to the degree of overlap between the first induction ring and the second induction ring. At the same time, the feedback and control of the distance that the power component drives the linkage block to move downward force the gate to overcome the water pressure and return to its initial position, thereby compensating for the wear on both sides of the gate and effectively preventing the gate from deviating along the water pressure direction. At the same time, the deflection problem caused by the screw assembly on the gate can be avoided, which may damage the power equipment or even cause it to break during the transmission of torque.

At the same time, a screw assembly 3 is movably sleeved inside the top of the gate 1, and the top of the outer surface of the screw assembly 3 is transmission-connected to a power device fixedly installed on the pillar. In the process of opening and closing the power device, the gate 1 can be driven to move up and down along the trajectory of the pillar under the transmission action of the screw assembly 3 to realize the opening and closing of the gate 1. A group of compensation components 5 are respectively provided on both sides of the back of the gate 1, as shown in FIG. Figure 3As shown, the compensating member 5 includes a supporting frame 4 fixedly mounted on the pillar, a power component 6 is fixedly mounted on one side of the top of the supporting frame 4, and a linkage block 7 whose side end is movably connected to the side of the gate 1 is fixedly mounted on the power shaft of the power component 6, so that the linkage block 7 can be forced to move downward under the action of the power component 6, and a plurality of groups of slots 8 arranged in a linear array are provided on the other side end of the linkage block 7, and the top of the inner wall of the slot 8 is in contact with a sphere 9 movably sleeved on the supporting frame 4, and then under the action of the slot 8 and the sphere 9, when the linkage block 7 moves downward, a reverse force can be applied to the linkage block 7 and the gate 1, and the gate 1 is forced to move in the direction opposite to the water pressure direction to compensate for the wear problem caused by the two sides of the gate 1 when they are in contact with the pillar for a long time.

[0018] like Figure 3 As shown, in the present technical solution, a first gap 10 is provided between the side of the gate 1 and the side of the support assembly frame 4, so that when wear occurs on both sides of the gate 1, under the action of water pressure, the gate 1 can move along the direction of the water pressure, and form a feedback system to control the downward movement distance of the linkage block 7 driven by the power component 6.

[0019] like Figure 4 , Figure 5 As shown, in the present technical solution, the screw assembly 3 includes a threaded connecting rod 11, and an annular groove 12 is provided at the bottom of the outer surface of the threaded connecting rod 11, and the annular groove 12 is movably engaged with a cylindrical groove 16 provided inside the top of the gate 1, and then when the power equipment drives the threaded connecting rod 11 to rotate, under the transmission action of the threaded connecting rod 11, the gate 1 can be forced to move up and down along the trajectory of the column.
