Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to an automatic flood control baffle deployment and retraction device. Background Technology

[0002] The flood control barrier is L-shaped and is mainly used as a splicing protection device for areas in flood zones that may be flooded. When two adjacent flood control barriers are placed close together, the vertical face faces the watershed, and the right-angled horizontal face is placed on the ground, facing the opposite direction. In this way, protection is achieved by placing heavy objects, sandbags, etc. on the horizontal surface.

[0003] The flood control area has a long route, and the placement of flood barriers requires a large number of barriers, which takes a long time and involves many people. Common methods include carrying them by hand or simply dropping them off the transport vehicle, which is prone to damage and inefficient. In some cases, the distance between the flood barriers is too long, making the installation very inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic flood control barrier deployment and retraction device, which has the advantages of rapid deployment of flood control barriers, high efficiency, and low manpower requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic flood control barrier deployment and retraction device, comprising:

[0006] Trailers are used to load flood barriers and unload them along the flood control route.

[0007] A lateral lifting and conveying mechanism is fixedly connected to one side of the trailer via a lifting device. A displacement mechanism is provided on the right side of the lateral lifting and conveying mechanism. A conveyor belt is provided on the lateral lifting and conveying mechanism located to the left of the displacement mechanism and spaced apart from it by a distance greater than the length of the flood control baffle.

[0008] The lower plate mechanism is disposed on one side of the trailer and is located above the displacement mechanism. The lower plate mechanism is used to limit the flood control baffle on the trailer during the downward movement.

[0009] A segmented conveying mechanism is provided between the displacement mechanism and the conveyor belt and above the lateral lifting conveying mechanism. The segmented conveying mechanism separates the flood control baffles one by one and moves them to one side of the conveyor belt.

[0010] A plate-laying mechanism is elastically disposed at the tail of the lateral lifting and conveying mechanism, which is used to lower the flood control baffle conveyed by the conveyor belt onto the road surface.

[0011] Furthermore, the lateral lifting and conveying mechanism includes a horizontally placed plate, and the conveyor belt is disposed on the top of the horizontally placed plate.

[0012] The horizontal placement panel can be adjusted in height via a lifting device. When placing the flood control panel, the lifting device lowers the horizontal placement panel to its lowest position, maintaining a distance of 15 centimeters from the ground. When the panel placement operation is completed, the lifting device raises the horizontal placement panel to its highest position. This ensures the stability of the panel placement operation and maintains a safe distance from the ground when the panel is not in use.

[0013] Furthermore, the displacement mechanism includes a mounting cavity disposed on the top of the horizontally placed plate. Two sets of damping plates are elastically disposed in the mounting cavity. Each set of damping plates is provided with a drive connecting seat. The two drive connecting seats are connected by multiple transmission shafts. A servo motor is disposed in the drive connecting seat for driving the multiple transmission shafts.

[0014] The lateral lifting conveyor mechanism is designed so that when the flood control baffles fall, they are placed on top of the lateral lifting conveyor after passing through the lowering mechanism. The lateral lifting conveyor is subjected to gravity, which puts pressure on the displacement mechanism. Thus, the entire displacement mechanism needs to bear the weight. By setting up shock-absorbing plates, the impact force of the overall equipment can be reduced, and it can also be ensured that there will be no problem of the baffles jumping when they come into contact with the conveyor shaft during the descent. After receiving multiple flood control baffles, the flood control baffles can be conveyed to the position of the segmented conveyor mechanism.

[0015] Furthermore, the lower plate mechanism includes an inclined guide plate, which is fixedly connected to one side of the trailer. Two limiting lower plate tracks are provided on the outer side of the inclined guide plate. The bottom end of the limiting lower plate tracks extends downward to form two lateral correction plates that limit the flood control baffles. An ejector arc plate is provided on the outer side of the inclined guide plate below the two inclined guide plates.

[0016] The lower plate mechanism is designed so that when the operator pushes one to five flood control baffles off the trailer, the bottom of the flood control baffles falls between the limiting lower plate tracks. After being blocked by the lateral correction plates on both sides, the baffles are damped by the lateral correction plates and slowly slide down between them. When they pass the ejector arc plate, the ejector arc plate guides the flood control baffles outward, allowing them to disengage from between the two lateral correction plates and land in the preset displacement mechanism position. In this way, the lateral correction plates will not obstruct the outward movement of the flood control baffles.

[0017] Furthermore, the segmented conveying mechanism includes a mounting base, which is fixedly connected to the lateral lifting conveying mechanism. Two hydraulic seats are fixedly connected to the mounting base, and a hydraulic cylinder is fixedly connected to one side of each of the two hydraulic seats. Inner baffles are fixedly connected to the two hydraulic cylinders, and multiple sets of rollers are arranged below the inner baffles. An acceleration conveying device is provided at one end of the hydraulic rod on the hydraulic cylinder.

[0018] Furthermore, the accelerated conveying device includes a servo motor, and the output end of the servo motor is provided with a conveying wheel.

[0019] The segmented conveyor mechanism allows the hydraulic rods on the two hydraulic cylinders to extend as the flood control baffles enter, moving multiple baffles between the inner baffle and the conveyor wheel. The hydraulic rods retract within the hydraulic cylinders, clamping the baffles together with the conveyor wheel and rollers. This causes the two servo motors to accelerate, pushing out the baffles that are in contact with the conveyor wheel. These pushed-out baffles then enter the conveyor belt, allowing multiple baffles to be conveyed out sequentially. The falling baffles can then be arranged at equal intervals along the installation route.

[0020] Furthermore, the plate-laying mechanism includes a plate-laying support hinged to the left side of the lateral lifting and conveying mechanism. Both the bottom of the plate-laying support and the lateral lifting and conveying mechanism are provided with spring seats, and the two spring seats are fixedly connected by a compression spring. A grounding wheel is fixedly connected to the bottom of the plate-laying support.

[0021] The plate-laying mechanism places the flood control baffles from the conveyor belt onto the laying route in sequence. It should be noted that when the flood control baffle moves onto the spring seat, the compression spring is compressed, and the plate-laying tray tilts. This tilts the flood control baffle onto the road surface, completing the unloading operation.

[0022] The technical effects and advantages of this utility model are as follows:

[0023] 1. The segmented conveying mechanism is designed so that when the displacement mechanism moves the flood control baffle to the position of the segmented conveying mechanism, the hydraulic rods on the two hydraulic cylinders can be extended when the flood control baffle enters. In this way, multiple flood control baffles enter between the inner baffle and the conveyor wheel. The hydraulic rods retract inside the hydraulic cylinders, so the conveyor wheel and roller clamp the flood control baffle. The two servo motors accelerate their rotation, which can accelerate the push out of the flood control baffles that are in contact with the conveyor wheel. After the pushed-out flood control baffles enter the conveyor belt, multiple flood control baffles can be conveyed out in sequence. The falling flood control baffles can be arranged at equal intervals along the installation route.

[0024] 2. The lower plate mechanism is designed so that when the operator pushes one to five flood control baffles off the trailer, the bottom of the flood control baffles falls between the limit lower plate tracks. After being blocked by the lateral correction plates on both sides, the baffles are damped by the lateral correction plates and slowly slide down between them. When they pass the ejector arc plate, the ejector arc plate guides the flood control baffles outward, allowing them to disengage between the two lateral correction plates and land in the preset displacement mechanism position. In this way, the lateral correction plates will not obstruct the outward movement of the flood control baffles.

[0025] 3. The height of the horizontally placed board can be adjusted by the lifting device. When placing the flood control barrier, the lifting device lowers the horizontally placed board to its lowest position, maintaining a distance of 15 cm from the ground. When the board placement operation is completed, the lifting device raises the horizontally placed board to its highest position. This is to ensure the stability of the board placement operation and to maintain a safe distance from the ground when the board is not being placed. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 An automatic flood control barrier deployment and retraction device shown includes:

[0032] Trailer 1 is used to load flood control barriers and unload them along the flood control route;

[0033] It is important to understand that the lateral lifting and conveying mechanism 2 includes a horizontally placed plate, and a conveyor belt is provided on the top of the horizontally placed plate.

[0034] The horizontal placement panel can be adjusted in height via a lifting device. When placing the flood control panel, the lifting device lowers the horizontal placement panel to its lowest position, maintaining a distance of 15 centimeters from the ground. When the panel placement operation is completed, the lifting device raises the horizontal placement panel to its highest position. This ensures the stability of the panel placement operation and maintains a safe distance from the ground when the panel is not in use.

[0035] The lateral lifting conveyor 2 is fixedly connected to one side of the trailer 1 via a lifting device. A displacement mechanism is provided on the right side of the lateral lifting conveyor 2. A conveyor belt is provided on the left side of the displacement mechanism and at intervals greater than the length of the flood control baffle.

[0036] The displacement mechanism includes a mounting cavity 21 set on the top of the horizontally placed plate. Two sets of damping plates 24 are elastically arranged in the mounting cavity 21. Both types of damping plates 24 are provided with drive connecting seats 23. The two drive connecting seats 23 are connected by multiple transmission shafts 22. The drive connecting seats 23 contain servo motors for driving the multiple transmission shafts 22.

[0037] The lateral lifting conveyor 2 is designed so that when the flood control baffle falls, it will be subjected to gravity when it lands on top of the lateral lifting conveyor 2 after passing through the lower plate mechanism 3. This will put pressure on the displacement mechanism, which will have to bear the weight. By setting the shock absorber 24, the impact force of the overall equipment can be reduced, and it can also be ensured that there will be no problem of the baffle jumping after it comes into contact with the conveyor shaft 22 during the descent. After receiving multiple flood control baffles, the flood control baffles can be conveyed to the position of the interval conveyor 5.

[0038] The lower plate mechanism 3 is located on one side of the trailer 1 and above the displacement mechanism. The lower plate mechanism 3 is used to limit the flood control baffle on the trailer 1 during the downward movement. The lower plate mechanism 3 includes an inclined guide plate 31, which is fixedly connected to one side of the trailer 1. Two limiting lower plate rails 32 are provided on the outer side of the inclined guide plate 31. The bottom end of the limiting lower plate rails 32 extends downward to form two lateral correction plates 33 that limit the flood control baffle. An ejector arc plate 34 is provided on the outer side of the inclined guide plate 31 below the two inclined guide plates 31.

[0039] With the lower plate mechanism 3 in place, when the operator pushes one to five flood control baffles stacked from the trailer 1, the bottom of the flood control baffles falls between the limiting lower plate tracks 32. After being blocked by the lateral correction plates 33 on both sides, the baffles are damped by the lateral correction plates 33 and slowly slide down between the lateral correction plates 33. When they pass the ejector arc plate 34, the ejector arc plate 34 guides the flood control baffles outward, and then they disengage from between the two lateral correction plates 33 and fall into the position of the preset displacement mechanism. In this way, the lateral correction plates 33 will not block the outward movement of the flood control baffles.

[0040] The interval conveying mechanism 5 is provided between the displacement mechanism and the conveyor belt and above the lateral lifting conveying mechanism 2. The interval conveying mechanism 5 separates the flood control baffles one by one and moves them to one side of the conveyor belt.

[0041] The interval conveying mechanism 5 includes a mounting base 51, which is fixedly connected to the lateral lifting conveying mechanism 2. Two hydraulic seats 52 are fixedly connected to the mounting base 51, and a hydraulic cylinder 54 is fixedly connected to one side of each hydraulic seat 52. An inner baffle 53 is fixedly connected to each hydraulic cylinder 54, and multiple sets of rollers are arranged below the inner baffle 53. An acceleration conveying device is provided at one end of the hydraulic rod 55 on the hydraulic cylinder 54. The acceleration conveying device includes a servo motor 56, and a conveying wheel 57 is provided at the output end of the servo motor 56.

[0042] With the segmented conveying mechanism 5 in place, when the displacement mechanism moves the flood control baffle to the position of the segmented conveying mechanism 5, the hydraulic rods 55 on the two hydraulic cylinders 54 can extend when the flood control baffle enters. In this way, multiple flood control baffles enter between the inner baffle 53 and the conveying wheel 57. The hydraulic rods 55 retract within the hydraulic cylinders 54, so the conveying wheel 57 and the roller clamp the flood control baffle. This causes the two servo motors 56 to accelerate their rotation, which can accelerate the push-out of the flood control baffles that are in contact with the conveying wheel 57. After the pushed-out flood control baffles enter the conveyor belt, multiple flood control baffles can be conveyed out in sequence, and the falling flood control baffles can be arranged at equal intervals along the installation route.

[0043] The plate-laying mechanism is flexibly positioned at the tail of the lateral lifting and conveying mechanism 2. The plate-laying mechanism is used to lower the flood control baffles conveyed by the conveyor belt onto the road surface. The plate-laying mechanism includes a plate-laying support plate 41 hinged to the left side of the lateral lifting and conveying mechanism 2. The bottom of the plate-laying support plate 41 and the lateral lifting and conveying mechanism 2 are both provided with spring seats 42. The two spring seats 42 are fixedly connected to each other by a compression spring 43. A grounding wheel 44 is fixedly connected to the bottom of the plate-laying support plate 41.

[0044] The plate-laying mechanism places the flood control baffles on the conveyor belt onto the laying route in sequence. It should be noted that when the flood control baffle moves onto the spring seat 42, the compression spring 43 is compressed, and the plate-laying support plate 41 is tilted. In this way, the flood control baffle is tilted and conveyed onto the road surface, completing the unloading operation.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
