Description

Technical Field

[0001] This utility model relates to the field of road cleaning technology, specifically a road cleaning device for municipal public works construction. Background Technology

[0002] After the road surface of municipal public works projects (such as concrete road surface or asphalt road surface) is laid, it needs to be watered for maintenance. At the same time, it washes away debris, garbage, dust and other things on the road surface to avoid some negative impacts on the newly laid road surface. Currently, water trucks are commonly used.

[0003] Patent CN204608684U discloses a water sprinkler truck, including a vehicle body and a water sprinkler system. The vehicle body includes a cab, a frame, and a water tank. The cab is connected to the frame, and the water tank is placed on the frame. The water sprinkler system is connected to the water tank. The water sprinkler system includes a spraying device and a road sprinkler device. The spraying device includes a spray gun, a support frame, longitudinal control components, and lateral control components. The support frame is mounted on the frame, and the spray gun is connected to the water tank and positioned on the support frame. Both the longitudinal and lateral control components are connected to the support frame. The road sprinkler device includes two sprinkler arms and two sprinkler arm control components. Each sprinkler arm has a water pipe connected to the water tank. One end of each sprinkler arm control component is connected to one sprinkler arm, and the other end of each sprinkler arm control component is connected to the frame. This water sprinkler truck can provide both spraying and road sprinkler services simultaneously, requiring only one driver to operate, saving manpower and reducing costs. Furthermore, the water sprinkler truck can control the spraying area according to road conditions, saving water.

[0004] However, the aforementioned water trucks still have the following problems in actual use:

[0005] When performing road maintenance and cleaning operations, water sprinkler trucks typically spray water onto the road surface using a water hose installed at the rear of the vehicle and parallel to the ground. This method not only helps maintain road conditions but also effectively removes debris. Some water sprinkler trucks are equipped with a fan-shaped spray function, which can simultaneously and evenly spray multiple lanes. When used on existing municipal roads, this reduces lane obstruction and improves efficiency.

[0006] However, using fan-shaped spraying on roads that are not yet open to traffic and are under maintenance presents some problems. Due to the nature of this spraying method, the area near the vehicle often receives more water, while areas further away from the vehicle may receive significantly less water or even no water coverage, resulting in uneven spraying. This is clearly undesirable for new road surfaces that require comprehensive and uniform maintenance, affecting the maintenance effect and reducing construction efficiency. Utility Model Content

[0007] In view of the shortcomings of the existing technology, this utility model provides a road cleaning device for municipal public works construction, which can make the water sprayed more evenly when watering and maintaining some municipal roads that are not open to traffic.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a road cleaning device for municipal public works construction, comprising a vehicle front, a base plate installed on the rear side of the vehicle front, and a water tank installed on the top of the base plate. An extension plate is fixedly connected to one end of the base plate away from the vehicle front, and support plates are fixedly connected to both ends of the extension plate. Three support openings are provided through the surface of each of the two support plates, and staggered openings are provided through one side of the two upper support openings. Fixed water spraying components and two movable water spraying components are connected to the three support openings in the two support plates. The fixed water spraying components and the two movable water spraying components are arranged in parallel, and both the fixed water spraying components and the two movable water spraying components are connected to the inside of the water tank. Transmission mechanisms are connected to both ends of the upper surface of the extension plate, and moving components are connected to the output ends of the two transmission mechanisms. The other ends of the two moving components are respectively connected to the two movable water spraying components.

[0009] Furthermore, motor housings are fixedly connected to both ends of the upper surface of the extension plate, and the ends of the two transmission mechanisms away from the movable water spray components are located in the two motor housings respectively.

[0010] Furthermore, the transmission mechanism includes a moving motor, a transmission belt, and two pulleys. The outer wall of the moving motor is fixedly connected to the inner wall of the motor housing. The output shaft of the moving motor is fixedly connected to one of the pulleys. The other pulley is located outside the motor housing and connected to one of the moving components. The transmission belt is sleeved on the outside of the two pulleys.

[0011] Furthermore, a protective cover is fixedly connected to the side wall of the motor housing, and the pulleys and pulleys connected to the moving components are both located inside the protective cover.

[0012] Furthermore, the movable component includes a lead screw and a movable plate. The outer walls at both ends of the lead screw are rotatably connected to the inner walls of the two support plates, and one end of the lead screw is fixedly connected to a pulley located inside the protective cover. The outer wall at the lower end of the movable plate is threadedly connected to the outer wall of the lead screw, and the upper end of the movable plate is connected to the movable water spray component.

[0013] Furthermore, the movable water spray assembly includes a movable pipe and a flexible hose. The outer wall of one end of the movable pipe is fixedly connected to the inner wall of the upper end of the movable plate. One end of the flexible hose is fixedly connected to the water tank, and the other end of the flexible hose is fixedly connected to the end of the movable pipe near the movable plate. Several spray holes are opened through the surface of the movable pipe. The water tank, flexible hose, movable pipe and several spray holes are internally connected. The outer walls of both ends of the movable pipe are slidably connected to the inner walls of the support openings of the two support plates.

[0014] Furthermore, the fixed water spray assembly includes a fixed pipe and a rigid pipe. One end of the rigid pipe is fixedly connected to the outer wall of the water tank, and the other end of the rigid pipe is fixedly connected to the middle of the fixed pipe. The outer walls of both ends of the fixed pipe are fixedly connected to the inner walls of the two support plates located at the lowest support openings. Several water spray holes are opened through the surface of the rigid pipe. The water tank, the rigid pipe, the fixed pipe and the several water spray holes are internally connected.

[0015] Furthermore, several nozzles are fixedly connected to the surfaces of both the fixed pipe and the movable pipe. The nozzles on the fixed pipe are connected to the interior of several water spray holes, and the nozzles on the movable pipe are connected to the interior of several water spray holes. The nozzles on the two movable pipes are aligned with the height of the two misaligned openings of the two support plates.

[0020] 4. This type of municipal public works road cleaning device has nozzles on the surface of the fixed pipe and the movable pipe that optimize the water flow direction and pressure, so that the water mist can be sprayed farther and more evenly, thereby improving the road cleaning and maintenance effect.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Please see Figures 1-5 A road cleaning device for municipal public works construction includes a vehicle front 1, a base plate 2 installed on the rear side of the vehicle front 1, and a water tank 3 installed on the top of the base plate 2. An extension plate 4 is fixedly connected to one end of the base plate 2 away from the vehicle front 1. Support plates 10 are fixedly connected to both ends of the extension plate 4. Three support openings 11 are opened through the surface of each of the two support plates 10, and staggered openings 12 are opened through one side of the two upper support openings 11. Fixed water spraying components and two movable water spraying components are connected to the three support openings 11 in the two support plates 10. The fixed water spraying components and the two movable water spraying components are arranged in parallel, and both the fixed water spraying components and the two movable water spraying components are connected to the inside of the water tank 3. Transmission mechanisms are connected to both ends of the upper surface of the extension plate 4. Movable components are connected to the output ends of the two transmission mechanisms, and the other ends of the two movable components are respectively connected to the two movable water spraying components.

[0029] like Figures 1 to 5As shown, when the municipal public works construction road cleaning device of this utility model is used for road maintenance on some municipal roads that are not open to traffic, the driver operates the water sprinkler truck to drive onto the road surface. Then, the driver activates two transmission mechanisms through the controller inside the truck head 1. After the two transmission mechanisms are activated, they will control two movable water spray components to extend to both sides of the water tank 3 through two moving components. Together with the fixed water spray components, they form three sets of water spray pipes. Then, the solenoid valve between the water tank 3 and the fixed water spray components and the two movable water spray components is opened through the controller inside the truck head 1. The maintenance water inside the water tank 3 can be sprayed onto the road surface through the fixed water spray components and the two movable water spray components, so that three lanes can be sprayed with water for maintenance at the same time. And because the fixed water spray components and the two movable water spray components are controlled separately, the sprayed maintenance water can be more even.

[0030] In addition, when the vehicle is being maintained on a road with only two lanes, the driver can retract one of the movable water spray components via the controller and close the solenoid valve connected to that movable water spray component. This allows the vehicle to be maintained using only the fixed water spray component and the other movable water spray component, making it more user-friendly and convenient to operate.

[0031] As a preferred embodiment of this utility model, motor housings 5 ​​are fixedly connected to both ends of the upper surface of the extension plate 4, and the ends of the two transmission mechanisms away from the movable water spray assembly are respectively located in the two motor housings 5.

[0032] More specifically, by setting up the motor housing 5, the transmission mechanism can be protected, reducing the impact of the water sprayed during the spraying of the fixed water spray assembly and the two movable water spray assemblies on the power source of the transmission mechanism.

[0033] As a preferred embodiment of the present invention, the transmission mechanism includes a moving motor 15, a transmission belt 18 and two pulleys 19. The outer wall of the moving motor 15 is fixedly connected to the inner wall of the motor housing 5. The output shaft of the moving motor 15 is fixedly connected to one of the pulleys 19. The other pulley 19 is located outside the motor housing 5 and connected to one of the moving components. The transmission belt 18 is sleeved on the outside of the two pulleys 19.

[0034] More specifically, when it is necessary to control the movable water spray component to extend and unfold to one side, simply turn on the moving motor 15 through the controller inside the front of the vehicle 1. The output shaft of the moving motor 15 drives the pulley 19 connected to it to rotate. This pulley 19 can then drive another pulley 19 to rotate through the transmission belt 18. In turn, the moving component can be rotated through the second pulley 19, and the movable water spray component can be displaced through the moving component.

[0035] As a preferred embodiment of this utility model, a protective cover 13 is fixedly connected to the side wall of the motor housing 5, and the pulley 19 and the pulley 19 connected to the moving component are both located inside the protective cover 13.

[0036] More specifically, by setting up the protective cover 13, the impact and damage caused by sprayed water or external objects to the pulley 19 and the drive belt 18 can be reduced.

[0037] As a preferred embodiment of this utility model, the movable component includes a lead screw 14 and a movable plate 17. The outer walls of both ends of the lead screw 14 are rotatably connected to the inner walls of the two support plates 10, and one end of the lead screw 14 is fixedly connected to a pulley 19 located inside the protective cover 13. The outer wall of the lower end of the movable plate 17 is threadedly connected to the outer wall of the lead screw 14, and the upper end of the movable plate 17 is connected to the movable water spray component.

[0038] More specifically, when the second pulley 19 rotates, the lead screw 14 connected to the pulley 19 will also rotate. After the lead screw 14 rotates, it can move the moving plate 17 on the surface left and right, and thus move the movable water spray assembly while the moving plate 17 moves left and right.

[0039] As a preferred embodiment of this utility model, the movable water spray assembly includes a movable pipe 9 and a flexible hose 8. The outer wall of one end of the movable pipe 9 is fixedly connected to the inner wall of the upper end of the movable plate 17. One end of the flexible hose 8 is fixedly connected to the water tank 3, and the other end of the flexible hose 8 is fixedly connected to the end of the movable pipe 9 near the movable plate 17. Several spray holes are opened through the surface of the movable pipe 9. The water tank 3, the flexible hose 8, the movable pipe 9 and the several spray holes are internally connected. The outer walls of both ends of the movable pipe 9 are slidably connected to the inner walls of the support openings 11 of the two support plates 10.

[0040] More specifically, when the movable plate 17 moves, the movable plate 17 will move with the movable pipe 9 connected to it within the support port 11, thereby extending the movable pipe 9 away from the movable plate 17 to expand the water spray area.

[0041] In addition, when water spraying is needed, simply open the solenoid valve between the hose 8 and the water tank 3, and the water pump located inside the water tank 3 will deliver water to the hose 8, and finally spray it onto the ground through several spray holes in the movable pipe 9 for maintenance and cleaning and rinsing of debris such as soil and leaves.

[0042] It should be noted that both solenoid valves and water pumps are existing, mature technologies, and will not be described in detail here.

[0043] As a preferred embodiment of this utility model, the fixed water spray assembly includes a fixed pipe 6 and a rigid pipe 16. One end of the rigid pipe 16 is fixedly connected to the outer wall of the water tank 3, and the other end of the rigid pipe 16 is fixedly connected to the middle of the fixed pipe 6. The outer walls of both ends of the fixed pipe 6 are fixedly connected to the inner walls of the two support plates 10 located at the lowest support openings 11. Several water spray holes are opened through the surface of the rigid pipe 16. The water tank 3, the rigid pipe 16, the fixed pipe 6 and the several water spray holes are internally connected.

[0044] More specifically, when the ground needs maintenance and water spraying, simply turn on the solenoid valve inside the rigid pipe 16 and the water tank 3. At this time, the water pump inside the water tank 3 can transport water through the rigid pipe 16 to the fixed pipe 6, and finally spray it out from several spray holes.

[0045] As a preferred embodiment of this utility model, a plurality of nozzles 7 are fixedly connected to the surfaces of both the fixed pipe 6 and the movable pipe 9. The plurality of nozzles 7 on the fixed pipe 6 are connected to the interior of a plurality of water spray holes, and the plurality of nozzles 7 on the movable pipe 9 are connected to the interior of a plurality of water spray holes. The plurality of nozzles 7 on the two movable pipes 9 are height aligned with the two misaligned openings 12 of the two support plates 10.

[0046] More specifically, by installing nozzles 7 at the spray holes and sprinkling holes of the fixed pipe 6 and the movable pipe 9, the water pressure can be increased firstly, and the spray can be made farther, thus increasing the cleaning range.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
