Description

TECHNICAL FIELD

[0001] The utility model relates to the field of warning board, specifically, relate to a warning board. BACKGROUND

[0002] When constructing in the tunnel, the warning board needs to be placed to remind the passing personnel to bypass the construction area. The existing warning board can only emit one kind of light, and the stimulation to the human eye is small. Since the light in the tunnel is dim, the unchanging light will cause visual fatigue of the human eye, which leads to the driving personnel easily ignoring the warning board, causing danger. Therefore, in view of the above status, it is urgent to develop a tunnel construction safety warning board with various warning lights, higher attraction to the human eye and better warning performance, to overcome the deficiencies in current actual application and meet the current demand.

[0003] Through retrieval, the prior art discloses a tunnel construction safety warning board in Chinese patent with patent application number 202223571054.2, which comprises a base, a plurality of casters are installed at the bottom of the base, a warning mechanism is installed on the base, the warning mechanism comprises: a transmission shaft, a mounting block, a warning light board, an electric motor, a first gear and a second gear, the transmission shaft is rotationally connected to the base, the top of the transmission shaft is provided with the mounting block, the mounting block is in the shape of a regular octahedron, one warning light board is installed on each of the six side surfaces of the mounting block, the colors of each warning light board are different, the electric motor is fixed in the base, a first gear is installed on the output shaft of the electric motor, a second gear is rotationally connected to one side of the first gear, the second gear is installed on the transmission shaft, and a jacking mechanism is installed on the outside of the base, but the following defects still exist:

[0004] (1) In the above patent document, the rotating warning light board is used to warn the vehicles in the tunnel. In the actual construction process, the dust in the construction site will adhere to the surface of the light board, affecting the warning effect of the light board. The construction personnel need to manually clean the surface of the light board regularly, which increases the working intensity of the construction personnel and increases the risk of accidents during construction.

[0005] (2) In the above patent document, the light emitted by the light board is used to warn the passing vehicles. However, the vehicles need to maintain a safe distance from the construction section in the tunnel when passing through the construction section. In the above patent document, the rotating light board is set at a fixed point to warn the passing vehicles. Only the approximate range of the construction site can be displayed, and the safe distance for driving cannot be specifically displayed to the driver, which reduces the warning effect of the device and the safety of driving in the tunnel during construction.

[0006] Therefore, we improve it and propose a warning board. UTILITY MODEL CONTENTS

[0007] The purpose of this invention is to address the problem that existing methods of using constantly rotating warning signs to alert vehicles in tunnels are ineffective. During actual construction, dust from the construction site adheres to the sign's surface, affecting its warning effect. This necessitates regular manual cleaning by construction workers, increasing their workload and the risk of accidents. While the signs use light to alert vehicles, vehicles must maintain a safe distance from the construction area. The aforementioned patents, which use fixed rotating signs, only show the approximate area of ​​the construction site and fail to provide drivers with specific safe distance information, thus reducing the warning effect and compromising driving safety in tunnels during construction.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A warning sign, including a base, also includes:

[0010] A walking assembly is fixedly connected to the bottom wall of the base for rapid movement of the device. The walking assembly includes a support frame fixedly connected to the bottom wall of the base and casters rotatably connected to the bottom wall of the support frame. The casters are symmetrically distributed about the central axis of the support frame.

[0011] A support assembly, located on the outer wall of the base, is used to provide stable support for the device;

[0012] A lifting assembly, located on the inner wall of the base, is used to adjust the warning height of the device;

[0013] Warning components are installed on the top wall of the lifting components to warn oncoming vehicles;

[0014] The cleaning component, located on the inner wall of the base, is used to clean dust from the exterior of the warning component.

[0015] As a preferred technical solution of this utility model, the support assembly includes a support hydraulic cylinder rotatably connected to the outer wall of the base and a support seat rotatably connected to the telescopic end of the support hydraulic cylinder. The support hydraulic cylinders are distributed about the central axis of the base.

[0016] As a preferred technical solution of this utility model, the lifting assembly includes a lifting motor fixedly connected to the inner wall of the base, a lifting screw fixedly connected to the output end of the lifting motor, a lifting seat slidably connected to the inner wall of the base, and a threaded sleeve fixedly connected to the inner wall of the lifting seat, wherein the threaded sleeve is threadedly engaged with the lifting screw.

[0017] As a preferred technical solution of this utility model, the warning component includes a transparent protective cover fixedly connected to the top wall of the lifting seat, a warning motor fixedly connected to the inner wall of the transparent protective cover, a light sign fixedly connected to the output end of the warning motor, a brush fixedly connected to the output end of the warning motor, an adjusting hydraulic cylinder rotatably connected to the inner wall of the lifting seat, a projection lamp rotatably connected to the inner wall of the lifting seat, and a transparent partition disposed on the outer wall of the lifting seat. The adjusting hydraulic cylinder, the projection lamp, and the transparent partition are evenly distributed about the inner wall of the lifting seat. The warning motor drives the brush to move along the outer wall of the transparent protective cover, and the adjusting hydraulic cylinder pushes the projection lamp to rotate about the lifting seat.

[0018] As a preferred technical solution of this utility model, the cleaning assembly includes a water tank fixedly connected to the inner wall of the lifting seat, a water inlet valve fixedly connected to the outer wall of the water tank, a water pump fixedly connected to the output end of the water pump, a water delivery pipe fixedly connected to the output end of the water pump, a spray pipe fixedly connected to the bottom wall of the water delivery pipe, and an oblique spray pipe fixedly connected to the top wall of the water delivery pipe. The water inlet valve extends outward through the outer wall of the lifting seat, the output end of the water pump extends outward through the outer wall of the lifting seat, and the spray pipe and the oblique spray pipe are evenly distributed about the outer wall of the water delivery pipe.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In the solution of this utility model:

[0021] 1. A water pump pumps cleaning fluid from the tank into the water supply pipe, which is then sprayed onto the surfaces of the transparent partition and the transparent protective cover through spray pipes and angled spray pipes, respectively, to wash away the dust adhering to their surfaces. At the same time, the warning motor drives the light sign to rotate, which in turn drives the brush to move along the outer wall of the transparent protective cover, cleaning away the dust adhering to the outer wall of the transparent protective cover. This achieves automatic cleaning of the warning components and solves the problem in the existing technology that uses continuously rotating warning light signs to warn vehicles passing through the tunnel. In actual construction, dust from the construction site would adhere to the surface of the light sign, affecting the warning effect of the light sign. Construction personnel would need to manually clean the surface of the light sign regularly, which would increase the workload of construction personnel and increase the risk of accidents during construction.

[0022] 2. By adjusting the hydraulic cylinder, the projection light is rotated to a set angle, turning on the projection light facing the outside of the construction site. This creates a bright safety warning light strip on the ground outside the site, reminding passing vehicles to maintain a safe distance from the construction site. This achieves the goal of warning vehicles in the tunnel to maintain a safe distance from the construction site, solving the problem of existing technologies that use light signs to remind vehicles, but vehicles need to maintain a safe distance from the construction section when passing through the tunnel. The aforementioned patent document uses a fixed rotating light sign to warn passing vehicles, which can only show the general area of ​​the construction site and cannot specifically show the driver the safe driving distance, thus reducing the warning effect of the device and the safety of driving in the tunnel during construction.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1 As shown, this embodiment proposes a warning sign, including a base 1, and further including:

[0031] The walking assembly is fixedly connected to the bottom wall of the base 1 for rapid movement of the device. The walking assembly includes a support frame 2 fixedly connected to the bottom wall of the base 1 and casters 21 rotatably connected to the bottom wall of the support frame 2. The casters 21 are symmetrically distributed about the central axis of the support frame 2.

[0032] A support component, located on the outer wall of the base 1, is used to provide stable support for the device;

[0033] A lifting assembly, located on the inner wall of base 1, is used to adjust the warning height of the device;

[0034] Warning components are installed on the top wall of the lifting components to warn oncoming vehicles;

[0035] A cleaning component, located on the inner wall of base 1, is used to clean dust from the exterior of the warning component;

[0036] Use the casters 21 to move the device to the outside of the construction site in the tunnel, and place the device evenly along the outside of the construction site.

[0037] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the support assembly further includes a support hydraulic cylinder 3 rotatably connected to the outer wall of the base 1 and a support seat 31 rotatably connected to the telescopic end of the support hydraulic cylinder 3. The support hydraulic cylinders 3 are distributed about the central axis of the base 1. When the device moves to the designated position, the support hydraulic cylinder 3 is controlled to push the support seat 31 downward and make it in close contact with the ground, so that the caster wheel 21 leaves the ground and completes the stable support of the device.

[0038] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, the lifting assembly further includes a lifting motor 4 fixedly connected to the inner wall of the base 1, a lifting screw 41 fixedly connected to the output end of the lifting motor 4, a lifting seat 42 slidably connected to the inner wall of the base 1, and a threaded sleeve 43 fixedly connected to the inner wall of the lifting seat 42. The threaded sleeve 43 is threadedly engaged with the lifting screw 41. When the lifting motor 4 is started, the lifting motor 4 drives the lifting seat 42 to move up and down through the lifting screw 41 and the threaded sleeve 43, and different warning heights can be adjusted and selected according to the actual environment.

[0039] like Figure 1 , Figure 2 and Figure 3As shown, in a preferred embodiment, based on the above method, the warning component further includes a transparent protective cover 5 fixedly connected to the top wall of the lifting seat 42, a warning motor 51 fixedly connected to the inner wall of the transparent protective cover 5, a light sign 52 fixedly connected to the output end of the warning motor 51, a brush 53 fixedly connected to the output end of the warning motor 51, an adjusting hydraulic cylinder 54 rotatably connected to the inner wall of the lifting seat 42, a projection lamp 55 rotatably connected to the inner wall of the lifting seat 42, and a transparent partition 56 disposed on the outer wall of the lifting seat 42. The adjusting hydraulic cylinder 54, the projection lamp 55, and the transparent partition 56 are evenly distributed about the inner wall of the lifting seat 42. The warning motor 51 drives the brush 53 to move along the outer wall of the transparent protective cover 5. The pressure cylinder 54 pushes the projection lamp 55 to rotate around the lifting seat 42, turning on the warning motor 51 and the light sign 52. The warning motor 51 drives the light sign 52 to rotate inside the transparent protective cover 5, displaying warning lights with various color changes and a fixed flashing frequency. At the same time as the warning motor 51 drives the light sign 52 to rotate, it also drives the brush 53 to move along the outer wall of the transparent protective cover 5, cleaning the dust attached to the outer wall of the transparent protective cover 5. Then, the hydraulic cylinder 54 is controlled to push the projection lamp 55 to rotate to the set angle, turning on the projection lamp 55 facing the outside of the construction site, so that a bright safety warning light strip is formed on the ground outside the site, reminding passing vehicles to maintain a safe distance from the construction site, thus completing the warning for vehicles passing through the tunnel.

[0040] like Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the cleaning assembly further includes a water tank 6 fixedly connected to the inner wall of the lifting seat 42, a water inlet valve 61 fixedly connected to the outer wall of the water tank 6, a water pump 63 fixedly connected to the inner wall of the water tank 6, a water pump 63 fixedly connected to the output end of the water pump 62, a water delivery pipe 64 fixedly connected to the output end of the water pump 63, a spray pipe 65 fixedly connected to the bottom wall of the water delivery pipe 64, and an inclined spray pipe 66 fixedly connected to the top wall of the water delivery pipe 64. Valve 61 extends outward through the outer wall of lifting seat 42, and the output end of water pump 63 extends outward through the outer wall of lifting seat 42. Spray pipe 65 and inclined spray pipe 66 are evenly distributed on the outer wall of water supply pipe 64. When a large amount of dust adheres to the surface of the device, water pump 63 is started to pump the cleaning liquid in water tank 6 into water supply pipe 64. Finally, the cleaning liquid is sprayed onto the surface of transparent partition 56 and transparent protective cover 5 through spray pipe 65 and inclined spray pipe 66 respectively, to rinse and clean the dust adhering to their surfaces, and automatically complete the self-cleaning of the device.

[0041] Specifically, when using this device: the casters 21 are used to move the device to the outside of the construction site in the tunnel. The device is then evenly placed along the outside of the construction site. Once the device reaches the designated position, the hydraulic cylinder 3 is controlled to push the support base 31 downwards and make close contact with the ground, ultimately causing the casters 21 to leave the ground, thus providing stable support for the device. The lifting motor 4 is then started. The lifting motor 4 drives the lifting base 42 to move up and down through the lifting screw 41 and the threaded sleeve 43. Different warning heights are adjusted according to the actual environment. The warning motor 51 and the light sign 52 are then activated. The warning motor 51 drives the light sign 52 to rotate inside the transparent protective cover 5, displaying warning lights with various color changes and a fixed flashing frequency. While rotating, the brush 53 moves along the outer wall of the transparent protective cover 5 to clean the dust adhering to the outer wall of the transparent protective cover 5. Then, the hydraulic cylinder 54 is controlled to push the projection lamp 55 to rotate to the set angle and turn on the projection lamp 55 facing the outside of the construction site, so that a bright safety warning light strip is formed on the ground outside the site, reminding passing vehicles to maintain a safe distance from the construction site, thus completing the warning for vehicles passing through the tunnel. When a large amount of dust adheres to the surface of the device, the water pump 63 is started to pump the cleaning fluid in the water tank 6 into the water pipe 64. Finally, the cleaning fluid is sprayed onto the surface of the transparent partition 56 and the transparent protective cover 5 through the spray pipe 65 and the oblique spray pipe 66 respectively, to wash and clean the dust adhering to their surfaces, thus automatically completing the self-cleaning of the device.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
