Folding floodgate

Abstract

This utility model relates to the field of gate technology and discloses a folding floodgate, including a gate seat. A motor is fixedly connected to the right side surface of the gate seat, and a water flow channel is opened through the front and rear of the gate seat. Support grooves connected to the water flow channel are opened on both the left and right sides of the gate seat. A gate plate is movably connected inside the water flow channel, and support members are provided on both the left and right sides of the gate plate. A positioning mechanism is provided on the upper surface of the gate seat. The positioning mechanism, which drives the positioning rod to rise and fall by a winch mechanism, makes the positioning rod press against the gate plate to form a rigid support after the gate plate is closed. This, together with the brake lock of the motor, forms a double electromechanical pressure-resistant structure, which significantly improves the stability of the gate plate against flood impact. The rising and falling of the positioning rod is automatically linked with the opening and closing of the gate plate, which ensures the mechanical reinforcement and pressure-bearing reliability when closed and avoids motion interference when opening, realizing safe and efficient coordination of flood control and rapid flood discharge.

Description

Technical Field

[0001] This utility model relates to the field of gate technology, specifically a folding flood control gate. Background Technology

[0002] To ensure flood control safety and maximize the comprehensive benefits of rivers, the management of rivers, artificial waterways, floodplains, flood storage areas, and flood detention areas mainly includes two major functions: river engineering management and social management. However, the existing flip-fold gates used in river management have poor corrosion resistance. Often, the surface of the gates will easily corrode after prolonged use, which will affect the service life of the gates and make them inconvenient for people to use.

[0003] Chinese patent discloses a tilting and folding gate for river management (authorization announcement number CN214530552U). This patented technology achieves excellent corrosion resistance through the combination of a frame, pipe body, support plate, left sealing bearing, rotating rod, sealing gasket, gate body, servo motor, right sealing bearing, mounting hole, anti-corrosion layer, modified polyphenylene sulfide coating layer, phenolic resin coating layer, and cyanopolymer coating layer. This solves the problem that existing tilting and folding gates for river management often have poor corrosion resistance, and their surfaces are prone to corrosion after prolonged use, which affects their service life and makes them inconvenient to use.

[0004] However, it has certain drawbacks: after the flip-fold gate is closed, the gate body only relies on the braking and locking force of the servo motor to maintain the closed state, lacking a rigid mechanical support structure; when encountering high water pressure or long-term water flow impact, the single motor locking method is prone to locking force decay or instantaneous overload failure, resulting in unexpected displacement or vibration of the gate body, which not only weakens the sealing effect, but may also cause damage to the gate structure, seriously affecting the reliability of flood control and the service life of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a folding floodgate to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A folding floodgate includes a gate seat, a motor is fixedly connected to the right side surface of the gate seat, and a water flow channel is opened through the front and back direction inside the gate seat. Support grooves communicating with the water flow channel are opened on both the left and right sides of the gate seat. A gate plate is movably connected inside the water flow channel, and support members are provided on both the left and right sides of the gate plate.

[0008] The upper surface of the gate seat is provided with a positioning mechanism, which includes a C-shaped frame. The inner left and right surfaces of the C-shaped frame are slidably connected to a positioning plate. The lower surface of the positioning plate is symmetrically fixed with two positioning rods in the left and right directions. The upper surface of the C-shaped frame is provided with a hoisting mechanism.

[0009] As a further embodiment of this utility model: the support member includes a support rod, a dynamic seal is installed on the outside of the support rod, and a bearing is installed at the end of the support rod away from the gate plate.

[0010] As a further embodiment of this utility model: the winch mechanism includes two support blocks, left and right. A second motor is fixedly connected to the left surface of the left support block. A winch rod is fixedly connected to the output end of the second motor. A second bearing is installed at the right end of the winch rod, and a winch rope is wound around the outside of the winch rod.

[0011] As a further embodiment of this utility model: the lower end of the C-shaped frame is fixed to the upper surface of the gate seat, and the positioning rod movably passes through the upper surface of the gate seat.

[0012] As a further embodiment of this utility model: the support member is located inside the support groove, the output end of the first motor is fixed to the right support rod, the end of the support rod away from the first bearing is fixed to one side surface of the gate plate, and the first bearing is fixed to one side surface of the inner side of the support groove.

[0013] As a further embodiment of this utility model: the lower end of the support block is fixed to the upper surface of the C-shaped frame, the second bearing is fixed to the left side surface of the right support block, the winch rope movably passes through the upper surface of the C-shaped frame, and one end of the winch rope is fixed to the upper surface of the positioning plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model features a positioning mechanism that uses a winch to drive the positioning rod to rise and fall. After the gate is closed, the positioning rod is pressed tightly against the gate to form a rigid support. This, together with the brake lock of the motor, forms a dual electromechanical pressure-resistant structure, significantly improving the stability of the gate against flood impact. The rising and falling of the positioning rod is automatically linked with the opening and closing of the gate, ensuring the mechanical reinforcement and pressure-bearing reliability when closed, while avoiding motion interference when opening, thus achieving safe and efficient coordination between flood control and rapid flood discharge.

Detailed Implementation

[0022] Please see Figures 1-3 In this embodiment of the utility model, the folding floodgate includes a gate seat 1. A motor 2 is fixedly connected to the right side surface of the gate seat 1, and a water flow channel 3 is opened through the front and rear direction inside the gate seat 1. Support grooves 4 connected to the water flow channel 3 are opened on both the left and right sides of the gate seat 1. A gate plate 5 is movably connected inside the water flow channel 3. Support members 6 are provided on both the left and right sides of the gate plate 5. The support members 6 are located inside the support grooves 4. The support members 6 include support rods 7. The output end of the motor 2 is fixedly connected to the right support rod 7. A dynamic seal 8 is installed on the outside of the support rod 7. A bearing 9 is installed on the end of the support rod 7 away from the gate plate 5. The end of the support rod 7 away from the bearing 9 is fixedly connected to one side surface of the gate plate 5. The bearing 9 is fixedly connected to one side surface of the inner side of the support groove 4.

[0023] The entire device was installed at the floodgate.

[0024] The water flow channel 3 is a circular channel. When the gate 5 is closed, its outer surface completely fits the inner surface of the water flow channel 3.

[0025] Motor 2 drives gate 5 to rotate via right support rod 7, which is used to open or close water flow channel 3; when gate 5 is in the vertical position, water flow channel 3 can be closed, and when gate 5 rotates in the horizontal direction, water flow channel 3 can be opened.

[0026] Motor 12 is preferably a servo motor, which is connected to the forward and reverse circuit and has a brake, meaning that the motor shaft cannot rotate after power is cut off.

[0027] The dynamic seal 8 includes a dynamic ring and a stationary ring. The dynamic ring is fixed to the outside of the support rod 7, and the stationary ring is fixed to the inside of the support groove 4, thus achieving a sealing effect.

[0028] Bearing 9 is a pedestal bearing. The pedestal bearing includes a bearing housing and a bearing fixed inside the bearing housing. The bearing includes an outer bearing ring and an inner bearing ring that rotates inside the outer bearing ring. The outer bearing ring is fixed in the bearing housing, and the support rod 7 is fixed in the inner bearing ring. Therefore, bearing 9 and support rod 7 are in a state of mutual rotation.

[0029] exist Figure 1 , Figure 4 and Figure 5 In the middle: A positioning mechanism 10 is provided on the upper surface of the gate seat 1. The positioning mechanism 10 includes a C-shaped frame 11. The lower end of the C-shaped frame 11 is fixed to the upper surface of the gate seat 1. Positioning plates 12 are slidably connected to the inner left and right surfaces of the C-shaped frame 11. Two positioning rods 13 are symmetrically fixed to the lower surface of the positioning plate 12 in the left and right directions. The positioning rods 13 movably pass through the upper surface of the gate seat 1. A hoisting mechanism 14 is provided on the upper surface of the C-shaped frame 11. The hoisting mechanism 14 includes two support blocks 1 on the left and right. 5. The lower end of the support block 15 is fixed to the upper surface of the C-shaped frame 11. The left side surface of the left support block 15 is fixed to the motor 2 16. The output end of the motor 2 16 is fixed to the winch rod 17. The right end of the winch rod 17 is equipped with the bearing 2 18. The bearing 2 18 is fixed to the left side surface of the right support block 15. The winch rod 17 is wrapped with a winch rope 19. The winch rope 19 moves through the upper surface of the C-shaped frame 11, and one end of the winch rope 19 is fixed to the upper surface of the positioning plate 12.

[0030] When the gate 5 rotates to the vertical position (closed state), and the positioning rod 13 descends to the lowest point, its rear surface just fits against the front surface of the gate 5 to support the gate 5. Under the premise that the motor 2 brakes and locks the gate 5, the stability of the gate 5 is further improved, and the braking performance of the motor 2 is weakened and the gate 5 is not rotated due to high water pressure.

[0031] Motor 2 16 is connected to the forward and reverse circuit and has a brake, meaning that the motor shaft cannot rotate after power is cut off;

[0032] After the winch rod 17 rotates, it can wind up or unwind the winch rope 19, which is used to drive the positioning rod 13 to rise and fall through the positioning plate 12.

[0033] The positioning plate 12 is preferably made of stainless steel, which has sufficient weight so that the positioning rod 13 can overcome resistance when it descends;

[0034] When the positioning rod 13 rises to its highest point, it no longer adheres to the front surface of the gate plate 5;

[0035] The positioning rod 13 is preferably made of low-alloy high-strength structural steel or precipitation-hardening stainless steel, which has high tensile strength and elongation to ensure that it does not undergo plastic deformation under high water pressure impact; the positioning rod 13 is a solid cylindrical structure, and the surface of the rod is treated with high frequency quenching to improve its resistance to bending fatigue.

[0036] Bearing 2 18 is a pedestal bearing, which includes a bearing housing and a bearing fixed inside the bearing housing. The bearing includes an outer bearing ring and an inner bearing ring that rotates inside the outer bearing ring. The outer bearing ring is fixed in the bearing housing, and the winch rod 17 is fixed in the inner bearing ring. Therefore, bearing 2 18 and winch rod 17 are in a state of mutual rotation.

[0037] The working principle of this utility model is as follows: When closing, the first motor 2 drives the right support rod 7 to rotate, which in turn drives the gate 5 to rotate until it is completely in contact with the inner wall of the water flow channel 3, blocking the water flow. After the first motor 2 brakes and locks the gate 5, the second motor 16 is started to rotate, causing the winch rod 17 to release the winch rope 19. The traction positioning plate 12 moves down, causing the positioning rod 13 to descend to the lowest position, so that its rear surface is tightly against the front surface of the gate 5 to form mechanical support. The second motor 16 brakes and locks the positioning rod 13, which, together with the first motor 2, resists the water pressure. When opening, the second motor 16 is started first to reverse and rewind the winch rope 19, causing the positioning rod 13 to rise and disengage from the gate 5. Then, the first motor 2 is started to reverse and drive the gate 5 to rotate, opening the water flow channel 3.
