Description

Technical Field

[0001] This invention relates to the field of roadblock indicator technology, and more specifically, to a nighttime traffic safety roadblock indicator. Background Technology

[0002] Nighttime roadblock indicator lights, also known as nighttime traffic warning lights, are a type of traffic safety facility. They are primarily available in red and yellow, with a visibility distance of 200-300 meters. They typically use dry cell batteries or rechargeable batteries as power sources, providing a usage time of 300-400 hours. Due to their long visibility range, they are widely used in roadblock sections to alert drivers. However, existing nighttime roadblock indicator lights lack a protective structure, leaving them exposed during the day when not in use. In weather conditions with poor air quality, a large amount of dust accumulates on the indicator surface within a short time, negatively impacting the light's illumination distance at night and hindering heat dissipation. This necessitates frequent cleaning and maintenance, increasing the workload for staff. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a nighttime traffic safety roadblock indicator light, which solves the problem that existing nighttime roadblock indicator lights lack a protective structure, resulting in the indicator lights remaining exposed during the day when they are not needed, causing a large amount of dust to accumulate on the surface of the indicator lights in a short period of time, requiring maintenance personnel to frequently clean and maintain the indicator lights.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A nighttime traffic safety roadblock indicator light includes a base, a protective box fixedly installed on the upper surface of the base, an indicator light body inside the protective box, and a drive component for driving the indicator light body to rise and fall installed at the bottom of the protective box.

[0012] Preferably, one of the cover plates is provided with a brush plate on the side near the indicator light body;

[0013] Another cover plate has a slot on the surface near the indicator light body.

[0014] Preferably, a connecting groove is provided on the surface of the cover plate away from the slot and close to the indicator light body, and a connecting block is slidably disposed in the connecting groove, with one side of the connecting block being fixedly connected to the brush plate;

[0015] A connecting rod is fixedly installed between the two sides of the inner wall of the connecting groove, and the connecting block is slidably disposed on one side of the connecting rod.

[0016] A first spring is fitted on the other side of the connecting rod body;

[0017] Several triangular blocks are fixedly installed at the bottom of the slot.

[0018] Preferably, two first partitions are fixedly installed on the lower surface of the brush plate near the triangular block, and a first rotating roller is rotatably installed between the two first partitions.

[0019] Preferably, a water tank is fixedly installed on the upper surface of the brush plate by a bracket, and a water supply pipe is fixedly installed in the middle of the upper surface of the water tank, with a one-way valve installed inside the water supply pipe;

[0020] Two push rods are movably installed on the side of the water tank away from the indicator light body. One end of each push rod extends into the interior of the water tank and is fixedly installed with a piston plate.

[0021] Several water outlet pipes are fixedly installed on the side of the water tank near the indicator light body, and each water outlet pipe is equipped with a spring-loaded safety valve.

[0022] A push plate is fixedly installed on the end of each push rod away from the water tank, and a second spring is sleeved on the side of the push rod body near the push plate.

[0023] A triangular plate is fixedly installed on the inner wall of the slot near the push plate.

[0024] Preferably, two second partitions are fixedly installed on the side of the push plate near the triangular plate, and a second rotating roller is rotatably installed between the two second partitions.

[0025] Preferably, a clearance groove is provided through the upper surface of the lifting platform;

[0026] The upper surface of the support frame is provided with a water collection trough, and the clearance groove and the water collection trough are located below the water supply pipe.

[0027] Preferably, a guide plate is fixedly installed on the inner wall of the water collection tank, and a water conveying hole is opened through one side surface of the inner wall of the water collection tank.

[0028] A drain pipe is fixedly installed on one side of the support frame at each water inlet position, and one end of each drain pipe extends to the outside of the protective box.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. By opening the control cover, the operator controls the dual-axis motor, causing its output shaft to drive the lead screw to rotate. The rotating lead screw, through threaded screwing, drives the lifting platform upwards along the positioning rod, moving the indicator light body to the outside of the protective box. When protection of the indicator light body is needed, the operator controls the dual-axis motor output shaft to reverse, causing the lifting platform to lower the indicator light body into the protective box. Subsequently, the operator controls the cover to close, preventing external dust from easily adhering to the surface of the indicator light body. This avoids the indicator light body being constantly exposed, which would cause a large amount of dust to accumulate on its surface in a short time, hindering its indication function and heat dissipation. This eliminates the need for frequent cleaning and maintenance of the indicator light body surface, reducing the workload of the operators.

[0031] 2. When the output shaft of the dual-axis motor at the top drives the lead screw to rotate, the output shaft of the dual-axis motor at the bottom drives the first bevel gear to rotate. Under the meshing action of the rotating first bevel gear and the second bevel gear, the shaft drives the second pulley to rotate. The rotating second pulley drives the first pulley to rotate through the transmission belt, thereby causing the bidirectional threaded rod to rotate. The rotating bidirectional threaded rod drives the two cover plates to move away from each other by the threaded advance, so that the cover plates open. When the output shaft of the dual-axis motor rotates in the opposite direction, the bidirectional threaded rod rotates in the opposite direction, so that the two cover plates close. There is no need for the staff to manually open or close the cover plates, thereby further reducing the workload of the staff.

[0032] 3. When the two covers are opened or closed, the brush plate can move relative to the indicator light body along with the covers. At this time, the brush plate can clean the dust on the surface of the indicator light body. When the covers are closed, the brush plate can be inserted into the slot and the inside of the slot is sealed to prevent a large amount of external dust from adsorbing on the surface of the brush plate. There is no need for staff to manually clean the indicator light body, which further reduces the workload of staff.

[0033] 4. When the brush plate enters the slot on one side, the inclined surface of the triangular block provides a pushing force to the first rotating roller. Under the combined action of the pushing force from the inclined surface of the triangular block and the first spring, the brush plate can move along the direction of the connecting groove. As the brush plate continues to move, one side moves to the other inclined surface of the triangular block. At this time, the triangular block no longer provides a pushing force to the first rotating roller, causing the brush plate to move in the opposite direction along the connecting groove. By setting multiple triangular blocks, the brush plate can move back and forth along the connecting groove when it moves, thereby increasing the friction frequency between the brush bristles and the surface of the indicator light body, thus enhancing the cleaning effect of the brush plate.

[0034] 5. After the cleaning water is injected into the water tank through the water supply pipe using the automatic water injection device, when the second rotating roller set on one side of the brush plate moves to the position of the triangular plate, the brush plate moves back and forth along the direction of the connecting groove under the action of the triangular block, causing the second rotating roller to move back and forth along the inclined surface of the triangular plate. Under the pushing force given by the inclined surface of the triangular plate and the pushing force of the second spring after compression and reset, the push rod drives the push plate to move back and forth, causing the piston plate to pressurize the inside of the water tank at intervals, so that the water flows out through the water outlet pipe, which cleans the surface of the brush plate and the indicator light body, causing the dust on the surface of the brush plate and the indicator light body to fall off, thereby improving the cleaning efficiency.

[0046] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0047] like Figures 1-10As shown, a nighttime traffic safety roadblock indicator light includes a base 1, a protective box 2 fixedly installed on the upper surface of the base 1, an indicator light body 4 inside the protective box 2, and a drive assembly 3 for driving the indicator light body 4 to rise and fall installed at the bottom of the protective box 2.

[0048] A groove 201 is provided on one side of the upper surface of the protective box 2. Two sliders 202 are slidably arranged in the groove 201. A cover plate 5 is fixedly installed on the upper surface of each slider 202.

[0049] Using the above technical solution, the staff moves the base 1 to the work site, then controls the cover 5 to open, activates the drive component 3, and drives the indicator light body 4 to rise to the outside of the protective box 2. The staff then turns on the indicator light body 4 to perform normal roadblock indication work. When daytime arrives and the roadblock indicator light body 4 is no longer needed, the staff controls the drive component 3 again to lower the indicator light body 4 into the protective box 2. Then, the cover 5 is closed to seal the inside of the protective box 2, making it difficult for external dust to adhere to the surface of the indicator light body 4. This prevents the indicator light body 4 from being exposed to the outside, which would cause a large amount of dust to accumulate on its surface in a short time, hindering the indication work and heat dissipation. This eliminates the need for maintenance personnel to frequently clean and maintain the surface of the indicator light body 4, reducing the workload of the staff.

[0050] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, in this embodiment, the drive assembly 3 includes a support frame 301, which is fixedly installed at the bottom of the protective box 2. A dual-axis motor 302 is fixedly installed on one side of the lower surface of the support frame 301. The output shaft end of the dual-axis motor 302 passes through the support frame 301 and is fixedly installed with a lead screw 303. A lifting platform 304 is threaded on one side of the lead screw 303. The upper surface of the lifting platform 304 is fixedly connected to the indicator light body 4.

[0051] A positioning rod 305 is fixedly installed on the upper surface of the support frame 301 on the side away from the lead screw 303, and the lifting platform 304 is slidably set on one side of the positioning rod 305.

[0052] The operator controls the dual-axis motor 302, causing its output shaft to drive the lead screw 303 to rotate. The rotating lead screw 303, through threaded screwing, drives the lifting platform 304 to rise along the positioning rod 305, causing the indicator light body 4 to move to the outside of the protective box 2. When it is necessary to protect the indicator light body 4, the operator controls the output shaft of the dual-axis motor 302 to reverse, causing the lifting platform 304 to drive the indicator light body 4 to descend and enter the protective box 2. Then, the operator controls the cover plate 5 to close, preventing dust from adhering to the surface of the indicator light body 4.

[0053] like Figure 1 , Figure 4 , Figure 5 As shown, it should be noted that a bidirectional threaded rod 6 is rotatably installed between the two sides of the inner wall of the slide groove 201. One side of the bidirectional threaded rod 6 passes through the slide groove 201 and is fitted with a first pulley 601.

[0054] The output end of the dual-axis motor 302 is fixedly installed with a first bevel gear 7. The support frame 301 is rotatably installed with a rotating shaft 8 near the first pulley 601. One side of the shaft of the rotating shaft 8 passes through the protective box 2 and is fitted with a second pulley 801. The surfaces of the first pulley 601 and the second pulley 801 are jointly fitted with a transmission belt 802.

[0055] The other end of the rotating shaft 8 passes through the support frame 301 and is fixedly mounted with a second bevel gear 803. The first bevel gear 7 meshes with the second bevel gear 803.

[0056] When the output shaft of the dual-axis motor 302 at the top drives the lead screw 303 to rotate, the output shaft of the dual-axis motor 302 at the bottom drives the first bevel gear 7 to rotate. Under the meshing action of the rotating first bevel gear 7 and the second bevel gear 803, the rotating shaft 8 drives the second pulley 801 to rotate. The rotating second pulley 801 drives the first pulley 601 to rotate through the transmission belt 802, thereby causing the bidirectional threaded rod 6 to rotate. The rotating bidirectional threaded rod 6 drives the two cover plates 5 to move away from each other by the threaded advance, so that the cover plates 5 open. When the output shaft of the dual-axis motor 302 rotates in the opposite direction, the bidirectional threaded rod 6 rotates in the opposite direction, so that the two cover plates 5 close. There is no need for the staff to manually open or close the cover plates 5, which further reduces the workload of the staff.

[0057] like Figure 4 , Figure 9 As shown, in the specific setup, one of the cover plates 5 is provided with a brush plate 9 on the side near the indicator light body 4;

[0058] Another cover plate 5 has a slot 10 on the surface near the indicator light body 4.

[0059] When the two covers 5 are opened or closed, the brush plate 9 can move relative to the indicator light body 4 along with the covers 5. At this time, the brush plate 9 can clean the dust on the surface of the indicator light body 4. When the covers 5 are closed, the brush plate 9 can be inserted into the slot 10 and the slot 10 is sealed to prevent a large amount of external dust from adsorbing on the surface of the brush plate 9. The staff does not need to manually clean the indicator light body 4, which further reduces the workload of the staff.

[0060] like Figures 8-10As shown, it can be understood that in this application, a connecting groove 11 is provided on the surface of the cover plate 5 away from the slot 10 and close to the indicator light body 4. A connecting block 1101 is slidably disposed in the connecting groove 11, and one side of the connecting block 1101 is fixedly connected to the brush plate 9.

[0061] A connecting rod 1102 is fixedly installed between the two sides of the inner wall of the connecting groove 11, and the connecting block 1101 is slidably disposed on one side of the connecting rod 1102.

[0062] A first spring 1103 is fitted on the other side of the connecting rod 1102;

[0063] Several triangular blocks 12 are fixedly installed at the bottom of the slot 10;

[0064] Two first spacers 13 are fixedly installed on the lower surface of the brush plate 9 near the triangular block 12, and a first roller 1301 is rotatably installed between the two first spacers 13.

[0065] When the brush plate 9 enters the slot 10 on one side, the inclined surface of the triangular block 12 provides a pushing force to the first rotating roller 1301. Under the combined action of the pushing force provided by the inclined surface of the triangular block 12 and the first spring 1103, the brush plate 9 can move along the direction of the connecting groove 11. As the brush plate 9 continues to move, one side moves to the other inclined surface of the triangular block 12. At this time, the triangular block 12 no longer provides a pushing force to the first rotating roller 1301, so that the brush plate 9 moves in the opposite direction along the connecting groove 11. By setting multiple triangular blocks 12, the brush plate 9 can move back and forth along the connecting groove 11 when it moves, thereby increasing the friction frequency between the bristles of the brush plate 9 and the surface of the indicator light body 4, and enhancing the cleaning effect of the brush plate 9.

[0066] like Figure 4 , Figure 9 As shown, in a specific setting, a water tank 1401 is fixedly installed on the upper surface of the brush plate 9 via a bracket 14, and a water supply pipe 1402 is fixedly installed in the middle of the upper surface of the water tank 1401. A one-way valve is installed inside the water supply pipe 1402.

[0067] Two push rods 1403 are movably installed on the side of the water tank 1401 away from the indicator light body 4. One end of each push rod 1403 extends into the water tank 1401 and is fixedly installed with a piston plate 1404.

[0068] Several water outlet pipes 1405 are fixedly installed on the side of the water tank 1401 near the indicator light body 4, and each water outlet pipe 1405 is equipped with a spring-loaded safety valve.

[0069] A push plate 1406 is fixedly installed on the end of the two push rods 1403 away from the water tank 1401. A second spring 1407 is sleeved on the side of the two push rods 1403 near the push plate 1406.

[0070] A triangular plate 15 is fixedly installed on the inner wall of slot 10 near the push plate 1406.

[0071] Two second spacers 16 are fixedly installed on the side of the push plate 1406 near the triangle plate 15, and a second roller 1601 is rotatably installed between the two second spacers 16.

[0072] By installing a one-way valve, clean water is prevented from flowing out of the water supply pipe 1402 when the piston plate 1404 pressurizes the inside of the water tank 1401. By installing a spring-loaded safety valve, cooling water is prevented from flowing out of the outlet pipe 1405 when the inside of the water tank 1401 is not pressurized.

[0073] After cleaning water is injected into the water tank 1401 through the water pipe 1402 using an automatic water injection device, when the brush plate 9 drives the second rotating roller 1601 on one side of the push plate 1406 to the position of the triangular plate 15, the brush plate 9 moves back and forth along the direction of the connecting groove 11 under the action of the triangular block 12, causing the second rotating roller 1601 to move back and forth along the inclined surface of the triangular plate 15. Under the pushing force given by the inclined surface of the triangular plate 15 and the pushing force of the second spring 1407 after compression and reset, the push rod 1403 drives the push plate 1406 to move back and forth, causing the piston plate 1404 to pressurize the inside of the water tank 1401 at intervals, so that the water flows out through the water outlet pipe 1405, which cleans the surface of the brush plate 9 and the indicator light body 4, causing the dust on the surface of the brush plate 9 and the indicator light body 4 to fall off, thus improving the cleaning efficiency.

[0074] like Figures 4-6 As shown, in a specific configuration, a clearance groove 17 is provided through the upper surface of the lifting platform 304;

[0075] A water collection trough 18 is provided on the upper surface of the support frame 301, and the clearance groove 17 and the water collection trough 18 are located below the water supply pipe 1402;

[0076] A guide plate 1801 is fixedly installed on the inner wall of the water collection tank 18, and a water conveying hole 1802 is opened through one side surface of the inner wall of the water collection tank 18.

[0077] A drain pipe 1803 is fixedly installed on one side of the support frame 301 at each water inlet 1802 position, and one end of each drain pipe 1803 extends to the outside of the protective box 2.

[0078] The clean water that flows out of the outlet pipe 1405 and washes away the dust is poured into the collection tank 18 through the avoidance groove 17, and discharged through the water supply pipe 1402 and the drain pipe 1803, which makes it convenient for staff to collect the clean water for recycling and reuse, thus saving water resources.

[0079] The working principle of this type of nighttime traffic safety roadblock indicator light:

[0080] In use, the operator first moves the base 1 to the work site, then opens the control cover 5. By controlling the dual-axis motor 302, its output shaft drives the lead screw 303 to rotate. The rotating lead screw 303 drives the lifting platform 304 to rise along the positioning rod 305 through threaded screwing, causing the indicator light body 4 to move to the outside of the protective box 2. When it is necessary to protect the indicator light body 4, the operator controls the output shaft of the dual-axis motor 302 to reverse, causing the lifting platform 304 to lower the indicator light body 4 into the protective box 2. Then, the operator controls the cover 5 to close, making it difficult for external dust to adhere to the surface of the indicator light body 4. This prevents the indicator light body 4 from being exposed to the outside, which would cause a large amount of dust to accumulate on its surface in a short time, which would be detrimental to the indication work and heat dissipation. Maintenance personnel do not need to frequently clean and maintain the surface of the indicator light body 4, reducing the workload of the operators.

[0081] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
