Description

Technical Field

[0001] The utility model relates to the technical field of flood prevention emergency devices, in particular to a water conservancy flood prevention retaining wall. Background Art

[0002] Retaining wall projects are not only important engineering measures in river control planning, but also an integral part of the flood control engineering system. Flood walls are common emergency devices for flood control and have been widely used in some indoor parking lots, underground parking lots, warehouses and other occasions. If a flood occurs, flood walls will be set up at the entrance of the indoor parking lot, underground parking lot or warehouse to reduce the risk of floodwaters overflowing the foundation height and flowing into the room.

[0003] Currently, some flood walls typically consist of two mounting posts and a baffle fixed between them. The distance between the posts should be at least the width of the warehouse entrance. The baffle is secured between the posts during use. When a flood occurs, the baffle effectively blocks the flow. To save space, retaining walls are typically disassembled and then reassembled for use, which is time-consuming and labor-intensive.

[0004] Chinese patent publication number CN215715002U discloses a flood wall. Before a flood arrives, the waterproof retaining wall is laid flat on the ground, serving as a pedestrian path. During a flood, the waterproof retaining wall is vertically snapped between two columns to block the floodwaters. While this flood retaining wall can be quickly assembled, its vertical placement places it completely under the lateral impact of the water flow. This can cause some assembled wall panels to wobble under the impact of flooding. Over time, this can lead to cracking of the wall surface, or even the wall being washed away by the floodwaters, resulting in poor flood control effectiveness. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to provide a water conservancy flood prevention retaining wall in view of the above-mentioned problems.

[0006] The technical solution adopted by the utility model is: a water conservancy flood retaining wall, comprising:

[0007] A base plate, with symmetrical columns at both ends of its top;

[0008] Two vertical baffles, the rotating ends of the vertical baffles are hinged between the two upright posts, and the two vertical baffles are symmetrical about the straight line where the two upright posts are located;

[0009] a conversion mechanism disposed inside the two upright posts, the conversion mechanism at either end being connected to the side walls of the two vertical baffles, the conversion mechanism being used to drive the two vertical baffles to rotate synchronously around their own rotation ends, so that the two vertical baffles can switch between a horizontal state and a vertical state;

[0010] The anti-dumping mechanism is arranged on the inner walls of the two columns facing each other. The anti-dumping mechanism can be connected to the two vertical baffles in a vertical state. When the vertical baffle on either side is impacted, the anti-dumping mechanism can enable the vertical baffle on the other side to provide support for it.

[0011] Through the above technical means, the conversion mechanism is used to control the two vertical baffles to switch between the horizontal state and the vertical state. When in the normal state, the vertical baffles are controlled to be in the horizontal state. When in the flood control state, the vertical baffles are controlled to be in the vertical state. The vertical baffles can block the flood. The anti-dumping mechanism enables the two vertical baffles to cooperate and support each other, thereby improving the stability and impact resistance of the flood retaining wall.

[0012] In some embodiments, the anti-dumping mechanism includes a gear, a rotating shaft, a connecting rod, a connecting seat and a movable latch. Two rotating shafts are rotatably provided on the inner walls of the opposite sides of the column. The two rotating shafts are both equipped with the gear and the connecting rod. The two gears are engaged with each other. The ends of the two vertical baffles away from their own rotating ends are provided with the connecting seat. The connecting rod and the connecting seat are both provided with a socket that can be plugged into and cooperate with the movable latch.

[0013] When the two vertical baffles are in a vertical state, the sockets on the connecting seat correspond to the sockets on the connecting rods, and the vertical baffles can be connected and fixed to the corresponding connecting rods through the movable latches.

[0014] In some embodiments, the connecting rod adopts a telescopic rod structure.

[0015] In some embodiments, the conversion mechanism includes a transmission shaft, a wire rope roller, a wire rope and a driving member. The internal rotation of the column is connected to the transmission shaft, and the wire rope roller is mounted on the transmission shaft. Two groups of wire ropes are wound around the two ends of the wire rope roller. Two through-holes are provided on the inner walls of the opposite sides of the column. The two groups of wire ropes are respectively connected to the side walls of the vertical baffles on both sides through the corresponding through-holes. The outer wall of the column is installed with the driving member for driving the transmission shaft to rotate.

[0016] In some embodiments, the driving member is a motor, and the output end of the motor is connected to the end of the transmission shaft.

[0017] In some embodiments, when the two vertical baffles are in a horizontal state, the wall surfaces of the two vertical baffles abut against the bottom plate, and the two vertical baffles can be assembled to form a flat surface;

[0018] When the two vertical baffles are in a vertical state, the facing side walls of the two vertical baffles abut against each other.

[0019] In some embodiments, inclined baffles are symmetrically provided on both sides of the base plate, and sliding grooves are symmetrically provided on both ends of the wall surface of the vertical baffle. The first end of the inclined baffle is hinged to the side of the base plate, and the second end of the inclined baffle is symmetrically provided with sliding members. The inclined baffle is slidably connected to the sliding groove via the sliding member, so that when the two vertical baffles are in a vertical state, they can drive the inclined baffles on both sides to be in a diagonal support state.

[0020] The beneficial effects of the utility model are:

[0021] 1. The vertical baffles on the bottom plate are adjusted to switch between horizontal and vertical states through a conversion mechanism. When flood control is needed, the conversion mechanism is used to control the vertical baffles to a vertical state, so that the vertical baffles can block the flood. When either side of the two vertical baffles is impacted by floods, the anti-dumping mechanism enables the vertical baffle on the other side to provide support for the impacted vertical baffle. Thus, the two vertical baffles can cooperate with each other to support each other, improving the stability and impact resistance of the flood retaining wall. At the same time, inclined baffles are also provided on the outside of the vertical baffles. The inclined baffles can provide auxiliary support for the vertical baffles. When facing the impact of floods, the vertical baffles and the inclined baffles can form two water-facing surfaces, thereby sharing the impact of the flood on the vertical baffles, further improving the impact resistance of the flood retaining wall.

[0030] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.

[0031] Combine Figures 1 to 4 As shown, this embodiment is a water conservancy flood retaining wall, comprising a base plate 1, two vertical baffles 3, a conversion mechanism 5 and an anti-dumping mechanism 6. Symmetrical columns 2 are provided at both ends of the top of the base plate 1. Two vertical baffles 3 are hinged between the two columns 2. The rotating ends of the vertical baffles 3 are hinged to the bottom of the inner wall of the two columns 2. The two vertical baffles 3 are symmetrical about the line where the two columns 2 are located. A conversion mechanism 5 is provided inside each of the two columns 2. The conversion mechanism 5 at either end is connected to the same side wall of the two vertical baffles 3. The conversion mechanism 5 is used to drive the two vertical baffles 3 to rotate synchronously around its own rotating end, so that the two vertical baffles 3 can switch between a horizontal state and a vertical state. An anti-dumping mechanism 6 is provided on the inner wall of the two columns 2 on the opposite side. The anti-dumping mechanism 6 can be connected to the two vertical baffles 3 in a corresponding state. When a vertical baffle 3 on either side is impacted, the anti-dumping mechanism 6 can enable the vertical baffle 3 on the other side to provide support for it.

[0032] In some embodiments, as Figure 3 As shown, the conversion mechanism 5 includes a transmission shaft 51, a wire rope roller 52, a wire rope 53, and a drive member 55. The transmission shaft 51 is rotatably connected to the interior of the column 2. The transmission shaft 51 is arranged horizontally within the column 2, with its ends facing the vertical baffles 3 on either side. A wire rope roller 52 is fixedly mounted on the transmission shaft 51, with a set of wire ropes 53 wound around each end of the wire rope roller 52. Two through-holes 54 are provided on the inner wall of the column 2 on opposite sides. The two sets of wire ropes 53 pass through the corresponding through-holes 54 and are connected to the side walls of the vertical baffles 3 on either side. A drive member 55 for rotating the transmission shaft 51 is mounted on the outer wall of the column 2. Specifically, in this embodiment, the drive member 55 is a motor, the output end of which is connected to the end of the transmission shaft 51. When using this device, the motor should be positioned away from the water as much as possible.

[0033] When the two vertical baffles 3 are in a horizontal state, the walls of the two vertical baffles 3 abut against the bottom plate 1, and the two vertical baffles 3 can be assembled to form a flat surface; at this time, the device can be placed at the entrance of a garage or a passage, and the horizontal surface formed by the vertical baffles 3 will not affect the normal passage of vehicles or pedestrians;

[0034] To prevent flooding, the two vertical baffles 3 need to be switched from a horizontal position to a vertical position. The motor is controlled to operate, driving the wire rope roller 52 to rotate and reel in the wire. The wire rope 53 pulls the two vertical baffles 3 around the hinge point and pulls them into a vertical position. When the two vertical baffles 3 are in the vertical position, their facing side walls abut against each other. By using the vertical baffles 3 to prevent flooding, a protective retaining wall can be quickly and conveniently established at the entrance of the passage to prevent and control flooding.

[0035] In some embodiments, inclined baffles 4 are symmetrically provided on both sides of the base plate 1, and sliding grooves 7 are symmetrically provided at both ends of the wall of the vertical baffle 3. The first end of the inclined baffle 4 is hinged to the side of the base plate 1, and the second end of the inclined baffle 4 is symmetrically provided with a sliding member 8. The inclined baffle 4 is slidably connected to the sliding groove 7 via the sliding member 8.

[0036] Through the cooperation of the sliding member 8 and the chute 7, the inclined baffles 4 can rotate synchronously during the rotation of the two vertical baffles 3 from the horizontal state to the vertical state, so that the inclined baffles 4 on both sides gradually tilt and support the outer sides of the vertical baffles 3. The inclined baffles 4 in the diagonal support state not only provide auxiliary support for the vertical baffles 3, but also improve the stability of the vertical baffles 3. At the same time, the vertical baffles 3 and the inclined baffles 4 can cooperate to form two water-facing surfaces. When a flood comes, the impact of the water flow is borne by the two water-facing surfaces respectively, thereby enhancing the impact resistance of the wall.

[0037] In some embodiments, as Figure 4 As shown, the anti-tipping mechanism 6 includes a gear 62, a rotating shaft 61, a connecting rod 63, a connecting seat 64, and a movable latch 65. Two symmetrical rotating shafts 61 are rotatably connected to the inner walls of the opposite sides of the column 2. The two rotating shafts 61 are each equipped with a gear 62 and a connecting rod 63, and the gears 62 on the two rotating shafts 61 are meshed with each other. The ends of the two vertical baffles 3 away from their own rotating ends are symmetrically provided with connecting seats 64. The connecting rod 63 and the connecting seat 64 are both provided with a socket that can be plugged into and matched with the movable latch 65. When the two vertical baffles 3 are in a vertical state, the socket on the connecting seat 64 corresponds to the socket on the connecting rod 63, and the vertical baffle 3 can be connected and fixed to the corresponding connecting rod 63 through the movable latch 65. Specifically, in this embodiment, the connecting rod 63 adopts a telescopic rod structure, such as a telescopic rod.

[0038] When the vertical baffle 3 is impacted by flood, the vertical baffle 3 on the water-facing side will be forced to tilt backward or tend to tilt backward, and drive the connecting rod 63 to rotate counterclockwise. The rotation of the connecting rod 63 will drive the rotating shaft 61 and the gear 62 thereon to rotate. Since the two gears 62 are engaged with each other, they can drive the connecting rod 63 on the rear side to rotate clockwise synchronously, thereby causing the vertical baffle 3 on the rear side facing away from the water to be pulled forward. Since the two vertical baffles 3 are close to each other and fit together, when the two vertical baffles 3 are subjected to relative forces, they will rely on each other, thereby causing the vertical baffle 3 on the rear side to provide support for the vertical baffle 3 on the front side facing the water, further improving the stability of the front vertical baffle 3 and preventing the vertical baffle 3 from being washed away by floods.

[0039] The implementation principle of a water conservancy flood retaining wall is as follows:

[0040] Under normal conditions, the vertical baffles 3 are in a horizontal state, and the oblique baffles 4 are located below the vertical baffles 3, allowing pedestrians and vehicles to pass smoothly. When flood prevention and control is needed, the control drive 55 is operated to drive the wire rope roller 52 to rotate and retract the wire rope 53. During the retraction process, the wire rope 53 pulls the two vertical baffles 3 to rotate around the hinge point. When the vertical baffles 3 are pulled into a vertical state, the control motor stops operating. At this time, the two vertical baffles 3 are close to each other. At the same time, as the vertical baffles 3 rotate toward the vertical state, the oblique baffles 4 rotate synchronously and gradually tilt and support the outside of the vertical baffles 3, providing auxiliary support for the vertical baffles 3. A flood retaining wall can be formed by the outer vertical baffles 3 and the oblique baffles 4 to prevent flooding. When the vertical baffle 3 is impacted by flood, the vertical baffle 3 on the water-facing side will be forced to tilt backward, driving the connecting rod 63 to rotate counterclockwise. The rotation of the connecting rod 63 drives the rotating shaft 61 and the gear 62 to rotate. Under the mutual engagement of the two gears 62, the connecting rod 63 on the rear side is driven to rotate clockwise. The vertical baffle 3 on the rear side is subjected to forward pulling force, so that the vertical baffle 3 on the rear side provides support and dependence for the vertical baffle 3 on the front side facing the water, thereby improving the stability of the vertical baffle 3 on the front side.

[0041] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
