Movable Water Injection Guardrail and Guardrail Device

Abstract

The present application relates to a movable water-filled guardrail and a guardrail device. The movable water-filled guardrail includes a guardrail body and a moving component. The moving wheels of the moving component facilitate the movement of the guardrail body. After the movable water-filled guardrail is moved into place, water is injected into the water storage cavity of the guardrail body through the water inlet. As the liquid level in the water storage cavity gradually rises, the moving elastic member is used to press down the moving wheels so that the moving wheels can be completely pressed into the accommodation space at the bottom of the guardrail body, and the bottom of the guardrail body contacts the road surface to increase the friction force. When it is necessary to move the movable water-filled guardrail, the water is directly drained through the drain port to reduce the overall weight of the guardrail body, the pressure on the moving component is reduced, and the moving elastic member releases part of its stored energy so that the moving wheels extend out of the accommodation space for easy movement. During the transportation and handling stage, since the guardrail body is hollow inside, the overall weight of the movable water-filled guardrail can be effectively reduced, improving the convenience of transportation.

Description

Technical Field

[0001] The present application relates to the technical field of guardrails, and in particular to a movable water-filled guardrail and a guardrail device. Background Art

[0002] During highway construction work, it is usually necessary to carry out without interrupting traffic. In order to warn the location of the maintenance construction work area, effectively isolate the work area, and guide normal vehicles to safely bypass the work area, road safety guardrails are often used for isolation.

[0003] In order to ensure the isolation effect of the guardrail, traditional guardrails are often inconvenient to move due to their heavy weight. To solve this problem, patent CN211006472U discloses a mobile road safety guardrail, which facilitates the movement of the guardrail by setting moving wheels. The moving wheels can be rotated inward to the bottom of the guardrail through the mounting rod. When it needs to be moved, the limit block is pressed, and the mounting rod resets the moving wheel under the action of the spring, which facilitates the movement of the guardrail. For example, patent CN213654438U discloses a foundation pit safety protection device for highway engineering. The bottom of the guardrail is provided with rollers and buffer springs, which can absorb the vibration and impact force from the ground and reduce the degree of bumping of the device. Suction cups are set on the side of the guardrail. When the device is moved to the required position, the telescopic rod can be adjusted to extend downward to adsorb the suction cup on the ground for fixation.

[0004] However, in the above scheme, the guardrail has a large deadweight, resulting in poor convenience in disassembly and transportation. In order to solve the transportation inconvenience caused by the deadweight of the guardrail, patent CN117905001A records a temporary anti-collision guardrail, in which rollers are arranged at the bottom of the water barrier body, which can be easily moved. After being pushed to a suitable position, liquid is poured into the interior of the water barrier body, and the rollers are retracted and fixed by using an elastic bearing device, a two-way clamping mechanism and a gear transmission mechanism. However, the roller arrangement structure in this scheme is complex, which increases the production and subsequent maintenance costs. Summary of the invention

[0010] In one embodiment, the connecting rod can rotate around the axis of the moving hole in the moving hole; a limiting ring is provided on the outer wall of the connecting rod. The limiting ring is located outside the mounting seat. When the distance between the connecting rod and the axis of the camshaft is the smallest, the limiting ring abuts against the outer bottom wall of the mounting seat; a matching hole communicating with the mounting cavity is provided on the bottom wall of the mounting seat. A limiting hole is provided on the limiting ring. The connecting rod can rotate to communicate the limiting hole with the matching hole; the movable water-filled guardrail further includes a limiting assembly. The limiting assembly is arranged in the mounting cavity and is located at the matching hole. The limiting assembly can be controlled to penetrate through the matching hole and the limiting hole.

[0011] In one embodiment, the movable water injection guardrail further includes a rotating assembly. The rotating assembly includes a rotating wheel. A mating wheel is provided at one end of the connecting rod that abuts against the camshaft. The rotating wheel is provided on the camshaft, and the rotating wheel can mesh with the mating wheel. The camshaft can drive the rotating wheel to rotate synchronously.

[0012] In one embodiment, both the rotating wheel and the mating wheel are bevel gears.

[0013] In one embodiment, the rotating assembly further includes a pushing member. The rotating wheel is reciprocally movable on the camshaft. The pushing member is controlled to push the rotating wheel in the direction of the mating wheel so that the rotating wheel can mesh with the mating wheel. The rotating assembly further includes a rotating elastic member. The rotating elastic member is provided on the rotating wheel to provide an elastic force for the rotating wheel to move in the direction away from the mating wheel.

[0014] In one embodiment, the movable water injection guardrail further includes a water spraying assembly. The water spraying assembly includes a spray head and a switching valve.

As the liquid level in the water storage cavity gradually rises, the overall weight of the guardrail body gradually increases, and the moving elastic member presses down the moving wheels.

When it is necessary to move the movable water-injected guardrail, the water is directly drained through the drain port to reduce the liquid level height in the water storage cavity, reduce the overall weight of the guardrail body, reduce the pressure on the moving components, and the moving elastic member releases part of its stored energy, so that the moving wheels extend out of the accommodation space, facilitating the movement of the guardrail body. The movable water-injected guardrail of the present application can not only meet the anti-collision requirements of the construction area, but also, during the transportation and handling stage, since the inside of the guardrail body is hollow, it can effectively reduce the overall weight of the movable water-injected guardrail and improve the convenience of transportation.

Detailed implementation manners

[0038] To make the above objects, features, and advantages of the present application more obvious and understandable, the following detailed description of the specific embodiments of the present application will be provided in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0039] Referring to Figure 1 , the movable water-filled guardrail 10 in an embodiment of the present application can at least improve the convenience of transportation and handling. Specifically, the movable water-filled guardrail 10 includes a guardrail body 100 and a moving assembly 200. A water storage cavity 110 is formed in the guardrail body 100. An inlet (not shown in the figure) and a drain port 120 are formed on the guardrail body 100. Both the inlet and the drain port 120 are communicated with the water storage cavity 110. A receiving space 130 is formed at the bottom of the guardrail body 100; the moving assembly 200 includes moving wheels 210 and moving elastic members 220. The moving wheels 210 are arranged at the bottom of the guardrail body 100 through the moving elastic members 220 and are located in the receiving space 130. The moving elastic members 220 are used to apply an elastic force to the moving wheels 210 in a direction away from the guardrail body 100, so that the moving wheels 210 can protrude from the receiving space 130.

[0040] In this embodiment, the movable water-filled guardrail 10 is used as a temporary guardrail, and water can be injected into the water storage cavity 110. In other embodiments, the movable water-filled guardrail 10 can be used as a semi-permanent guardrail or a permanent guardrail, and thus concrete or water can also be injected into the water storage cavity 110.

[0041] The movement of the guardrail body 100 can be facilitated by the movement wheels 210 of the moving component 200. After the movable water-filled guardrail 10 is in place, water can be injected into the water storage cavity 110 of the guardrail body 100 through the water inlet. As the liquid level in the water storage cavity 110 gradually rises, the overall weight of the guardrail body 100 gradually increases, and the moving elastic member 220 presses down on the movement wheels 210. When the liquid level in the water storage cavity 110 reaches a certain height, the compression amount of the moving elastic member 220 increases, so that the movement wheels 210 can be completely pressed into the accommodation space 130 at the bottom of the guardrail body 100, and the bottom of the guardrail body 100 contacts the road surface, increasing the friction force. When it is necessary to move the movable water-filled guardrail 10, the water is directly drained through the drain port 120 to reduce the liquid level height in the water storage cavity 110, reduce the overall weight of the guardrail body 100, reduce the pressure on the moving component 200, and the moving elastic member 220 releases part of its stored energy, so that the movement wheels 210 extend out of the accommodation space 130, facilitating the movement of the guardrail body 100. The movable water-filled guardrail 10 of the present application can not only meet the anti-collision requirements of the construction area, but also, during the transportation and handling stage, since the guardrail body 100 is hollow, it can effectively reduce the overall weight of the movable water-filled guardrail 10 and improve the convenience of transportation.

[0042] In one embodiment, an anti-slip pad 140 is provided on the bottom wall of the guardrail body 100. To prevent the guardrail body 100 from sliding on the road surface under the influence of external forces in the water injection state, the anti-slip pad 140 on the bottom wall of the guardrail body 100 is used to increase the friction damping between the guardrail body 100 and the road surface and enhance the protection effect of the movable water-filled guardrail 10. As Figure 1 and 3 shown, the anti-slip pad 140 can be a rubber pad structure. As Figure 2 shown, the anti-slip pad 140 can also be a burr structure or a brush structure, as long as it can increase the friction between the guardrail body 100 and the road surface.

[0043] As Figure 1 shown, in this embodiment, the cross-sectional dimension of the guardrail body 100 increases from top to bottom, so that the center of gravity of the guardrail body 100 after water injection is lowered, improving the stability on the road surface. As Figure 2 shown, in the first embodiment, the cross-sectional dimension of the guardrail body 100 can also be the same from top to bottom. Of course, in other embodiments, the size and shape of the guardrail body 100 can also be other shapes.

[0044] As Figure 3As shown, in the second embodiment, the present application may also be provided with rib plates inside the guardrail body 100, and water flow ports are provided on the rib plates. Thus, the rib plates can support the side walls of the guardrail body 100 to enhance its structural strength, and will not hinder the guardrail body 100 from storing water inside through the water flow ports. In other embodiments, the two opposite side surfaces of the guardrail body 100 are impact-facing surfaces, and the impact-facing surfaces can be any one of the following or a combination thereof: single-slope type slope surface, F-type slope surface, enhanced slope surface, straight-wall type slope surface, arc-shaped slope surface, etc.

[0045] As Figure 1 shown, in this embodiment, the accommodating space 130 is formed by the inward concavity of the bottom wall of the guardrail body 100. As Figure 4 shown, in the third embodiment, an anti-slip structure may be provided on the bottom wall of the guardrail body 100, and the accommodating space 130 is surrounded by the anti-slip structures, and the moving assembly 200 is arranged in the space surrounded by the anti-slip structures.

[0046] Referring to Figure 1 、 Figure 5 and Figure 6 , in one embodiment, the movable water injection guardrail 10 further includes a water spraying assembly 300. The water spraying assembly 300 includes a spray head 310 and a switch valve 320. The spray head 310 is arranged at the drain port 120 of the guardrail body 100 through the switch valve 320, and the switch valve 320 is controlled to be able to communicate the drain port 120 with the inner space of the spray head 310. Since the movable water injection guardrail 10 is arranged along the road surface and has a large water storage cavity 110, when it is necessary to cool and dust the road surface, the spray head 310 can be opened through the switch valve 320, so that the water in the water storage cavity 110 is sprayed onto the road surface through the drain port 120 by the spray head 310, improving the microenvironment of the road surface. Specifically, the drain port 120 is located at a position close to the bottom wall of the guardrail body 100, and the pressure generated by the self-weight of the water can be utilized to generate a jet of water through the spray head 310.

[0047] Further, the switch valve 320 includes a switch driving member 321, a movable plate 322 and a drain pipe 323. The movable plate 322 is arranged between the drain pipe 323 and the guardrail body 100. The switch driving member 321 is used to drive the movable plate 322 to move between the drain pipe 323 and the guardrail body 100 to control the communication size between the drain pipe 323 and the drain port 120. In this embodiment, the movable plate 322 may also be provided with a communication hole. When the switch driving member 321 drives the movable plate 322 to rotate to a certain angle between the drain pipe 323 and the drain port 120 through the transmission gear set, the communication hole on the movable plate 322 is staggered with the space in the drain pipe 323, which can prevent drainage. When the movable plate 322 rotates until the communication hole is connected to the drain pipe 323, drainage can be achieved. Specifically, the switch valve 320 further includes a switch seat 324, on which the switch driver 321, the movable plate 322 and the drain pipe 323 are all arranged, and the switch seat 324 is installed at the drain port 120 of the guardrail body 100. The switch seat 324 can provide an installation support platform for the switch driver 321, the movable plate 322 and the drain pipe 323.

[0048] In the embodiment, in order to improve the water spraying effect, the switch valve 320 can also be replaced by a pumping device.

[0049] In one embodiment, the movable water-filled guardrail 10 further includes a solar panel 400, and the switch valve 320 is electrically connected to the solar panel 400, and the solar panel 400 is used to convert solar energy into electrical energy to provide electrical energy for the switch valve 320. Specifically, the movable water-filled guardrail 10 further includes an energy storage battery, the solar panel 400 is electrically connected to the energy storage battery, and the switch valve 320 is electrically connected to the energy storage battery, so that the converted electrical energy is stored in the energy storage battery, which is convenient for driving other electrical components.

[0050] See also Figure 1 , Figure 7 and Figure 9 In one embodiment, the movable water injection guardrail 10 further includes a guide assembly 500, the guide assembly 500 includes at least two guide sleeves 510 that are mutually sleeved, and each guide sleeve 510 can move relative to each other, and the movable elastic member 220 is disposed on the guide sleeve 510. Specifically, the movable elastic member 220 is disposed in the guide sleeve 510. By providing the guide assembly 500, the stability of the upward and downward telescopic movement of the movable wheel 210 can be further improved, and the possibility of shaking during the movement can be reduced. In other embodiments, the movable elastic member 220 is a spring, and can also be sleeved outside the guide sleeve 510.

[0051] In order to facilitate adaptation to different traffic flows, variable lanes, that is, changeable lanes, will be set on the road, and generally variable lane traffic lights will be set at intersections. In an embodiment of the present application, the movable water-filled guardrail 10 is used to be set on the lane dividing line. When it is necessary to switch the direction of the variable lane, since the frictional force between the movable water-filled guardrail 10 and the road surface increases after water injection, it is not easy to move, and thus it is not easy to realize the switching of the lane direction.

[0052] Therefore, in this embodiment, the movable water-filled guardrail 10 further includes a mounting seat 600 and a lifting assembly 700. The mounting seat 600 is arranged in the accommodation space 130 through a movable elastic member 220. The lifting assembly 700 is arranged on the mounting seat 600. The moving wheel 210 is connected to the lifting assembly 700, and the lifting assembly 700 is controlled to drive the moving wheel 210 to move downward. After the guardrail body 100 is filled with water, the movable elastic member 220 is compressed, and the moving wheel 210 retracts into the accommodation space 130, resulting in difficulty in moving the guardrail body 100 in the water-filled state. To move it, only drainage can be used. However, in the construction site or on the road surface where the traffic flow does not stop, there will be problems with inconvenient water injection. By driving the moving wheel 210 to extend through the lifting assembly 700, it is convenient to move the guardrail body 100 in the water-filled state.

[0053] Further, the lifting assembly 700 includes a lifting driving member 710 and a camshaft 720. The lifting driving member 710 is controlled to drive the camshaft 720 to rotate. The moving wheel 210 includes a roller 212 and a connecting rod 214 rotatably connected to the roller 212. The connecting rod 214 is movably arranged on the mounting seat 600 and can abut against the outer wall of the camshaft 720. Under the gravity of the guardrail body 100, the moving wheel 210 abuts against the camshaft 720. When it is necessary to drive the moving wheel 210 to extend, the lifting driving member 710 drives the camshaft 720 to rotate to push the moving wheel 210 to move downward. In this embodiment, an installation cavity 610 is formed in the mounting seat 600. The lifting assembly 700 is arranged in the installation cavity 610. A moving hole 620 communicating with the installation cavity 610 is formed in the bottom wall of the mounting seat 600. The connecting rod 214 is movably inserted through the moving hole 620 and can abut against the outer wall of the camshaft 720. By arranging the lifting assembly 700 in the installation cavity 610, it is convenient to protect the lifting assembly 700 and provide an installation platform for the lifting assembly 700. Specifically, the lifting driving member 710 is electrically connected to the solar panel 400. Further, the lifting driving member 710 is electrically connected to the solar panel 400 through a storage battery. The solar panel 400 is used to convert solar energy into electrical energy to provide electrical energy for the lifting driving member 710.

[0054] In one embodiment, the lifting driving member 710 is a motor. In another embodiment, to meet the jacking power requirement, the lifting driving member 710 can be a hydraulic rod. The telescopic movement of the hydraulic rod drives the eccentric wheel to rotate, and then drives the camshaft 720 to rotate. In other embodiments, the lifting driving member 710 can also be other structures capable of driving the camshaft to rotate.

[0055] In this embodiment, the connecting rod 214 can rotate around the axis of the moving hole 620 within the moving hole 620. Since the connecting rod 214 can rotate within the moving hole 620, it is convenient to achieve the universal adjustment of the moving wheel 210, and further convenient to adjust the position of the movable water injection guardrail 10.

[0056] Specifically, a limiting ring 216 is provided on the outer wall of the connecting rod 214. The limiting ring 216 is located outside the mounting seat 600, and when the distance between the connecting rod 214 and the axis of the camshaft 720 is the smallest, the limiting ring 216 abuts against the outer bottom wall of the mounting seat 600. By providing the limiting ring 216, the position of the connecting rod 214 can be restricted, and thus the position of the moving wheel 210 can be restricted.

[0057] Further, a mating hole 630 communicating with the mounting cavity 610 is formed in the bottom wall of the mounting seat 600. A limiting hole 217 is formed in the limiting ring 216. The connecting rod 214 can rotate to align the limiting hole 217 with the mating hole 630. The movable water injection guardrail 10 further includes a limiting component 800. The limiting component 800 is disposed in the mounting cavity 610 and at the mating hole 630. The limiting component 800 can be controlled to pass through the mating hole 630 and the limiting hole 217. After the limiting component 800 passes through the mating hole 630 and the limiting hole 217, the rotation of the connecting rod 214 relative to the mounting seat 600 can be restricted, thereby achieving the purpose of the moving wheel 210 rolling in a fixed direction and achieving the purpose of restricting the moving direction of the movable water injection guardrail 10. In other embodiments, the limiting component 800 can also be omitted, and at the same time, the limiting hole 217 and the mating hole 630 can also be omitted.

[0058] In this embodiment, two limiting holes 217 are formed in the limiting ring 216, and the two limiting holes 217 are uniformly arranged around the axis of the connecting rod 214. The roller 212 can roll relative to the connecting rod 214. When the connecting rod 214 rotates, it can drive the roller 212 to rotate, realizing the adjustment of the rolling direction of the roller 212. When any one of the limiting holes 217 corresponds to and communicates with the mating hole 630, the rolling direction of the roller 212 at this time is a fixed direction, for example, the horizontal moving direction of the movable water injection guardrail 10. In other embodiments, the number of the limiting holes 217 can also be determined according to the required moving directions. For example, if the required fixed moving directions include horizontal movement and vertical movement, the number of the limiting holes 217 can be four, and the four limiting holes 217 are uniformly arranged around the axis of the connecting rod 214.

[0059] Specifically, the limiting component 800 includes a limiting rod, a limiting elastic member, and a limiting driving member. The limiting rod is installed in the mounting seat 600 through the limiting elastic member, so that one end of the limiting rod penetrates into the mating hole 630. The limiting driving member is controlled to control the movement of the limiting rod, so that the limiting rod further penetrates into the limiting hole 217. In this embodiment, the limiting elastic member is used to provide an elastic force for the limiting rod in the direction from the limiting hole 217 to the mating hole 630, so that when limiting is not required, the limiting rod will not extend out of the mounting seat 600 through the mating hole 630. Further, the limiting driving member can be an electromagnet. When it is necessary to drive the limiting rod to extend, the electromagnet is energized to repel the limiting rod to extend or adsorb the limiting rod to extend.

[0060] In other embodiments, the limiting driving member can also be other components capable of driving the limiting member to expand and contract. The limiting elastic member is used to provide an elastic force for the limiting rod in the direction from the mating hole 630 to the limiting hole 217, so that when limiting is not required, the limiting driving member enables the limiting rod to overcome the elastic force of the limiting elastic member and will not extend out of the mounting seat 600 through the mating hole 630. Or the limiting component 800 can be a component such as an electric push rod.

[0061] In one embodiment, the movable water injection guardrail 10 further includes a rotating component 900. The rotating component 900 includes a rotating wheel 910. A mating wheel 218 is provided at one end of the connecting rod 214 that abuts against the camshaft 720. The rotating wheel 910 is arranged on the camshaft 720, and the rotating wheel 910 can be engaged with the mating wheel 218. The camshaft 720 can drive the rotating wheel 910 to rotate synchronously. When the rotating wheel 910 is engaged with the mating wheel 218, the connecting rod 214 abuts against the camshaft 720 at the position closest to the axis of the camshaft 720.

[0062] Specifically, as Figure 10 shown, the camshaft 720 only forms a pushing protrusion on the surface of the outer semicircle. By driving the rotating wheel 910 to drive the mating wheel 218 to rotate, and then driving the connecting rod 214 to rotate, the position of the connecting rod 214 is adjusted to realize the relative communication between the limiting hole 217 and the mating hole 630, which is convenient for the limiting component 800 to limit the further rotation of the connecting rod 214 to fix the moving direction of the moving wheel 210.

[0063] Further, both the rotating wheel 910 and the mating wheel 218 are bevel gears, which can change the rotation direction to facilitate the purpose of driving the connecting rod 214 to rotate. In other embodiments, the rotating wheel 910 and the mating wheel 218 can also have other structures as long as the purpose of driving the mating wheel 218 to rotate can be achieved.

[0064] In one embodiment, the rotating assembly 900 further includes a pushing member 920. The rotating wheel 910 is reciprocally movable on the camshaft 720. The pushing member 920 is controlled to push the rotating wheel 910 in the direction towards the mating wheel 218, so that the rotating wheel 910 can engage with the mating wheel 218. Specifically, the moving direction of the connecting rod 214 is perpendicular to the axis of the camshaft 720. In this embodiment, when the limiting assembly 800 is inserted into the limiting hole 217 and the mating hole 630, the pushing member 920 is triggered to stop pushing the rotating wheel 910, so that the rotating wheel 910 is separated from the mating wheel 218 and does not drive the connecting rod 214 to continue rotating.

[0065] Specifically, the pushing member 920 is disposed in the installation cavity 610. The pushing member 920 includes a pushing driving member and a push rod. The pushing driving member is configured to drive the push rod to move, so as to push the rotating wheel 910 in the direction towards the mating wheel 218. Further, a pushing inclined surface is formed at an end of the push rod. The push rod can extend into the side of the rotating wheel 910 facing away from the mating wheel 218, and the rotating wheel 910 is pushed by using the pushing inclined surface. In other embodiments, the pushing member 920 is disposed on the side of the rotating wheel 910 facing away from the mating wheel 218, and the pushing driving member can also directly drive the push rod to extend towards the rotating wheel 910.

[0066] In one embodiment, the pushing member 920 can be an electric push rod. In other embodiments, the pushing member 920 can also be a hydraulic rod or other components capable of pushing the rotating wheel 910 to move.

[0067] In one embodiment, the rotating assembly 900 further includes a rotating elastic member 930. The rotating elastic member 930 is disposed on the rotating wheel 910 and is configured to provide an elastic force for the rotating wheel 910 to move in the direction away from the mating wheel 218. When the pushing member 920 does not push the rotating wheel 910, under the action of the rotating elastic member 930, the rotating wheel 910 can be separated from the mating wheel 218.

[0068] Referring to Figures 11 to 13 , in one embodiment, the present application also discloses a guardrail device 1. The guardrail device 1 includes at least two movable water-filled guardrails 10 in any one of the above embodiments; splicing members 20 are disposed on an outer side wall of each guardrail body 100, and the splicing members 20 of two adjacent movable water-filled guardrails 10 are connected to each other.

[0069] Specifically, the splicing member 20 includes a connecting plate 202 and a connecting pin 204. Among them, the connecting plate 202 is horizontally arranged on the outer side of the side wall of the guardrail body 100. A connecting hole can be provided in the middle of the connecting plate 202 to vertically insert the connecting pin 204 into the connecting holes of the connecting plates 202 provided on the outer sides of the two movable water injection guardrails 10. The connecting plate 202 can be specifically fixed on the two side surfaces of the movable water injection guardrail 10 by welding. The connecting plates 202 at the splicing positions between the front and rear adjacent sections of the movable water injection guardrails 10 can be in a vertically staggered relationship, that is, the connecting plate 202 at the front end of the movable water injection guardrail 10 is uniformly set at a slightly higher position, and the connecting plate 202 at the rear end of all the movable water injection guardrails 10 is uniformly set at a slightly lower position. Thus, when connecting the front and rear movable water injection guardrails 10, the connecting plate 202 at the higher position at the front end of the movable water injection guardrail 10 can just reach above the connecting plate 202 at the lower position at the rear end of the previous movable water injection guardrail 10. The connecting holes on the front and rear two connecting plates 202 are aligned through the height difference between the two to form a vertically penetrating pin hole. Thus, the connecting pin 204 can be inserted at the position where the connecting plates 202 at the ends of the front and rear two water tanks overlap up and down, and the connecting pin 204 is inserted into the pin hole of the connecting plate 202 with a vertical stagger, and the front and rear movable water injection guardrails 10 at all levels are connected to form the overall guardrail device 1. In other embodiments, the splicing member 20 can also be of other structural shapes as long as it can connect the two movable water injection guardrails 10.

[0070] As Figure 13 shown, in one embodiment, the guardrail device 1 can be used as a semi-permanent guardrail or a permanent guardrail, which is arranged on the lane separation line of the road surface for separating the upper and lower lanes. At least one movable water injection guardrail 10 can move horizontally from one lane separation line to another lane separation line. By enabling the movable water injection guardrail 10 to move horizontally from one lane separation line to another lane separation line, the Figure 13 variable lane switching function shown is realized, or the guardrail device 1 is driven to be arranged in a specific structure according to the construction requirements.

[0071] Refer to Figures 7 to 10 together, for example, Figure 13 shows a guardrail device 1 formed by connecting 9 movable water injection guardrails 10 before and after. According to the figure shown, the movable water injection guardrails 10 are sequentially numbered from No. 1 to No. 9 from left to right. If the guardrail device 1 is composed of Figure 13The middle state is switched to the upper state. For the movable water injection guardrails 10 from No. 1 to No. 3, the pushing member 920 drives the rotating wheel 910 to engage with the mating wheel 218. The lifting driving member 710 drives the camshaft 720 to drive the rotating wheel 910 to rotate synchronously, and then drives the moving wheel 210 to rotate until the limiting hole 217 communicates with the mating hole 630 relatively. The limiting assembly 800 is inserted into the limiting hole 217 and the mating hole 630 to realize the locking of the lateral rolling direction of the moving wheel 210. During this process, the connecting rod 214 abuts against the part of the outer wall of the camshaft 720 where there is no pushing protrusion, and thus no downward movement occurs. After the rolling direction of the moving wheel 210 is locked, the pushing member 920 releases the pushing on the rotating wheel 910, and the rotating wheel 910 is separated from the mating wheel 218 and no longer drives the connecting rod 214 to rotate. At this time, the lifting driving member 710 drives the camshaft 720 to continue to rotate, and the pushing protrusion part of the camshaft 720 pushes the moving wheel 210 to move downward and extend out. At this time, the movable water injection guardrails 10 from No. 1 to No. 3 can achieve stable lateral movement.

[0072] For the movable water injection guardrails 10 from No. 4 to No. 6, the pushing member 920 does not push the rotating wheel 910 to engage with the mating wheel 218, and only the lifting driving member 710 drives the camshaft 720 to rotate so that the moving wheel 210 moves downward and extends out. At this time, the moving wheel 210 can still achieve universal rotation. The movable water injection guardrails 10 from No. 7 to No. 9 remain stationary. Therefore, when switching the variable lane, push the movable water injection guardrails 10 from No. 1 to No. 3 to move laterally, and the movable water injection guardrails 10 from No. 4 to No. 6 are inclined under traction to realize the state of the guardrail device 1 Figure 13 to switch from the middle state to the upper state. After the switching is completed, the lifting driving member 710 drives the camshaft 720 to rotate so that the moving wheel 210 abuts against the outer wall of the camshaft 720 where there is no pushing protrusion part, and the moving wheel 210 retracts into the accommodation space 130 of the guardrail body 100 under the gravity of the guardrail body 100.

[0073] Similarly, when the guardrail device 1 needs to be switched to the lower state, then lock the moving wheels 210 of the movable water injection guardrails 10 from No. 7 to No. 9 in the lateral moving state, and keep the movable water injection guardrails 10 from No. 1 to No. 3 stationary.

[0074] In other embodiments, the water in the movable water injection guardrails 10 from No. 1 to No. 3 can be drained, and the moving wheels 210 can be extended by reducing the weight to facilitate the displacement of the movable water injection guardrails 10. After moving in place, water is injected into the movable water injection guardrails 10 again so that the bottom wall of the movable water injection guardrails 10 abuts against the road surface to realize the switching of the variable lane.
