A water collecting port 1 for collecting rainwater is provided on the top of the water collecting box 6. The water collecting port 1 is wide at the top and narrow at the bottom. The opening is enlarged to facilitate the collection of rainwater, so that rainwater flows into the water collecting box 6 along the inclined surface of the water collecting port 1 at the fastest speed. A filter screen 10 is provided between the water collecting port 1 and the water collecting box 6. By providing the filter screen 10, impurities can be effectively prevented from entering the water collecting box 6 and blocking the water pumping pipe 21 from pumping water, thereby affecting the flushing effect of rainwater on the sign body 5. A sign body 5 is fixed on the fixed frame 2, and slide grooves 3 are symmetrically provided on the side walls of the fixed frame 2. By providing the slide grooves 3, it is convenient for the movable plate 9 to extend into the cavity 11 and slide on the fixed frame 2. A brush plate 25 for cleaning dust on the sign body 5 is provided between the sign body 5 and the slide grooves 3.

[0033] Reference Figure 2 and Figure 4 As shown, a cavity 11 is opened in the fixed frame 2, a water pump 20 is arranged in the water collecting box 6, a water pump 21 and a third water pipe 22 are arranged on the water pump 20, and a flushing mechanism is arranged between the third water pipe 22 and the fixed frame 2. By setting the flushing mechanism, part of the dust on the sign body 5 can be washed away, and the flushing mechanism is placed in the cavity 11. When in use, the water pump 20 is started to pump the water in the water collecting box 6 and the rainwater to the third water pipe 22 through the water pump 21 for use by the flushing mechanism, and then the rainwater is sprayed onto the surface of the sign body 5 through the flushing mechanism to wash away part of the dust on the surface of the sign body 5. It should be noted that the water pump is a prior art, and its function is to pump water out of the container, which will not be explained in detail here.

[0034] Reference Figure 2 , Figure 4 and Figure 6 As shown, the flushing mechanism includes a second water pipe 16, the second water pipe 16 is fixedly connected to a third water pipe 22, the second water pipe 16 and the third water pipe 22 are perpendicular to each other, and the third water pipe 22 is connected to the center of the second water pipe 16, so that rainwater from the third water pipe 22 enters the second water pipe 16 and flows into two ends of the second water pipe 16 in two ways;

[0035] The flushing mechanism also includes two first water pipes 13, which are symmetrically arranged on both sides of the second water pipe 16, and rainwater flowing into the two ends of the second water pipe 16 is transported to the first water pipe 13 in two ways to facilitate subsequent use;

[0036] The flushing mechanism also includes multiple water outlet pipes 24, one end of the multiple water outlet pipes 24 is fixedly connected to the first water pipe 13, and the rainwater transported into the first water pipe 13 is further transported into the multiple water outlet pipes 24; the other end of the multiple water outlet pipes 24 is provided with a nozzle 14 for spraying water on the surface of the sign body 5, and the water in the multiple water outlet pipes 24 is sprayed onto the surface of the sign body 5 through the nozzle 14, thereby achieving the effect of flushing dust.

[0037] When it is necessary to flush the sign body 5, the staff starts the water pump 20 and the water pipe 21 to transport the rainwater in the water collecting tank 6 along the third water pipe 22 to the second water pipe 16. The second water pipe 16 transports the rainwater to the outlet pipe 24 through the connected first water pipe 13. Finally, the rainwater in the outlet pipe 24 is sprayed onto the surface of the sign body 5 through the nozzle 14, thereby flushing away some of the dust on the surface of the sign body 5.

[0038] Reference Figure 4 As shown, the inner and outer sides of the fixed frame 2 are respectively provided with a first water filter net 4 and a second water filter net 15, and the first water filter net 4 and the second water filter net 15 are located below the nozzle 14. The first water filter net 4 and the second water filter net 15 are provided to discharge the water used to wash the sign body 5 out of the fixed frame 2 to prevent rainwater from accumulating on the surface of the fixed frame 2, accelerating the rust of the fixed frame 2, and reducing the service life of the fixed frame 2. In addition, the first water filter net 4 has a supporting function to strengthen the fixing effect of the sign body 5. A plurality of fixing frames 7 are provided on one side of the fixed frame 2, and a plurality of fixing holes 8 are opened on the fixing frame 7. The fixing frame 7 is welded to the fixed frame 2 to ensure the firmness of the fixed frame 2. The fixing frame 2 and the fixing holes 8 opened on the fixing frame 7 are used to conveniently fix the fixed frame 2 to other components.

[0039] Reference Figure 5 and Figure 6 As shown, a cleaning mechanism is provided between the brush plate 25 and the chute 3, and the dust not washed off the surface of the sign body 5 is cleaned by the cleaning structure. The cleaning mechanism includes a moving plate 9, both ends of which pass through the chute 3 and are slidably connected to the fixed frame 2. The moving plate 9 is limited to move in other directions by the chute 3 so as not to affect the cleaning of the brush plate 25 connected to the moving plate 9;

[0040] The cleaning mechanism also includes a plurality of cylinders 29, which are fixedly connected to the movable plate 9; the cleaning mechanism also includes a plurality of round rods 27, which are fixedly connected to the brush plate 25; the plurality of round rods 27 are telescopically slidable in the cylinder 29 through springs 26, and a limit plate 28 is provided at one end of the round rod 27 extending into the cylinder 29, and the round rod 27 slides in the cylinder 29 and is limited by the limit plate 28 to prevent the round rod 27 from slipping out of the cylinder 29 and affecting the cleaning of the brush plate 25. The purpose of setting the spring 26 is to squeeze the brush plate 25 close to the identification plate body 5 through the rebound effect of the spring 26, increase the friction between the brush plate 25 and the identification plate body 5, and then increase the cleaning force and enhance the cleaning effect. By setting the round rod 27 and the cylinder 29 The function is to prevent the spring 26 from bending due to the force applied when the brush plate 25 cleans the nameplate body 5, so that the brushing surface of the brush plate 25 is no longer in contact with the surface of the nameplate body 5, affecting the cleaning effect. Compared with directly squeezing the brush plate 25 through the movable plate 9, directly squeezing the brush plate 25 has a larger friction force, which may cause the brush plate 25 to be restricted in movement due to friction, thereby failing to achieve the purpose of cleaning the surface of the nameplate body 5. The spring 26 is used as a buffer, which not only allows the brush plate 25 to be close to the surface of the nameplate body 5, but also when the friction force is large and hinders the movement of the brush plate 25, the friction between the brush plate 25 and the surface of the nameplate body 5 can be reduced by squeezing the spring 26, so that the brush plate 25 can continue to move, thereby achieving the purpose of cleaning.

[0041] Reference Figure 6 As shown, sliders 23 are provided at both ends of the movable plate 9, and the sliders 23 are placed in the cavity 11. The movable plate 9 is driven to move by moving the sliders 23, thereby driving the brush plate 25 connected to the movable plate 9 to move.

[0042] Reference Figure 2 and Figure 3 As shown, a guide rod 12 and a reciprocating screw rod 18 are provided in the cavity 11, the guide rod 12 is fixedly connected to the fixed frame 2, and the slider 23 slides on the guide rod 12, and the guide rod 12 provides guidance for the movement of the slider 23. One end of the reciprocating screw rod 18 is rotatably connected to the fixed frame 2 through an auxiliary plate 19, and the auxiliary plate 19 is fixedly connected to the fixed frame 2. A motor 17 is provided on the inner wall of the cavity 11, and the output end of the motor 17 is coaxially fixed with the other end of the reciprocating screw rod 18. The slider 23 penetrates the reciprocating screw rod 18, and the slider 23 is threadedly connected to the reciprocating screw rod 18. The slider 23 can be driven to move up and down by rotating the reciprocating screw rod 18, thereby realizing the up and down movement of the brush plate 25, thereby realizing cleaning.

[0043] When it is necessary to clean the surface of the sign body 5, the staff starts the motor 17 to drive the reciprocating screw 18 to rotate, and the reciprocating screw 18 drives the slider 23 to move up and down, thereby driving the movable plate 9 connected to the slider 23 and the brush plate 25 connected to the movable plate 9 to move up and down, thereby achieving the purpose of automatic cleaning, saving the staff's time and energy, and improving work efficiency.

[0044] The working principle of the present invention is as follows:

[0045] When flushing the sign body 5, rainwater is collected into the water collecting box 6 through the water collecting port 1, and the rainwater in the water collecting box 6 is transported to the second water pipe 16 along the third water pipe 22 through the water pump 20 and the water pipe 21. The second water pipe 16 transports the rainwater to the outlet pipe 24 through the connected first water pipe 13, and finally the rainwater in the outlet pipe 24 is sprayed onto the surface of the sign body 5 through the nozzle 14, thereby washing away part of the dust on the surface of the sign body 5, replacing the manual water washing by the staff, thereby reducing the labor intensity of the staff.

[0046] When cleaning the sign body 5, start the motor 17 to drive the reciprocating screw 18 to rotate, and rotate the reciprocating screw 18 to drive the slider 23 to move up and down, thereby driving the movable plate 9 connected to the slider 23 and the brush plate 25 connected to the movable plate 9 to move up and down, thereby achieving the purpose of automatic cleaning, saving the staff's time and energy, and improving work efficiency. At the same time, the spring 26 squeezes the brush plate 25 through reaction to slide close to the surface of the sign body 5, thereby increasing the cleaning effect.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
