[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1 , Figure 4 and Figure 5 The utility model provides an embodiment: a traffic road noise suppression device, including a bottom plate 1, both sides of the upper part of the bottom plate 1 are fixedly connected with columns 3, the first sound absorbing panels 4 are inserted into the two columns 3, the second sound absorbing panels 5 are inserted into the upper part of the first sound absorbing panels 4, a cleaning component 18 is arranged inside the right column 3, the cleaning component 18 is used to clean the dust attached to the outside of the sound insulation board, the lower part of the second sound absorbing panel 5 is fixedly connected with a mounting tube 8, the inside of the mounting tube 8 is fixedly connected with a fixing rod 9, the outside of the fixing rod 9 is slidably connected with sliders 10, the outside of the two sliders 10 is rotatably connected with adjusting rods 12, and the other ends of the multiple adjusting rods 12 are A clamping block 13 is rotatably connected, springs 11 are sleeved on both sides of the outside of the fixing rod 9, mounting blocks 17 are fixedly connected to the front sides of the outsides of the two columns 3, a second through hole 15 is opened inside the first sound-absorbing panel 4, the mounting tube 8 is plugged into the second through hole 15, first through holes 14 are opened on both sides of the inside of the mounting tube 8, two clamping blocks 13 are slidably connected inside the two first through holes 14, card grooves 16 are opened on both sides of the inside of the first sound-absorbing panel 4, and the two clamping blocks 13 are engaged with the two card grooves 16, a transparent glass window 6 is installed inside the second sound-absorbing panel 5, a reflective warning strip 7 is arranged on the outside of the second sound-absorbing panel 5, and mounting holes 2 are opened on both sides of the inside of the bottom plate 1.

[0026] When installing the first sound absorbing board 4 and the second sound absorbing board 5, first, the operator needs to squeeze the two blocks 13. As the blocks 13 are squeezed, the two blocks 13 will drive the adjustment rod 12 connected to the inside to move together. The movement of the adjustment rod 12 will further drive the two sliders 10 connected to the other end to move to both sides outside the fixed rod 9. During the movement of the two sliders 10, they will squeeze the springs 11 set on both sides of the outside of the fixed rod 9, so that the two springs 11 are deformed by force. When the two blocks 13 move to the inside of the mounting tube 8, the mounting tube 8 is inserted into the inside of the second through hole 15, and then the two blocks 13 are continued to move until they reach the position of the two slots 16. In this process, the reaction force of the two springs 11 will cause the two blocks 13 to automatically snap into the inside of the two slots 16, thereby achieving a stable fixation. This design facilitates the installation of the sound insulation board. During installation, there is no need to use a large number of bolts and rivets for fixing, which greatly simplifies the operation steps. The installation of the sound absorbing board can be completed with simple squeezing and insertion operations. This installation method is not only simple and convenient to operate, but also significantly saves time and manpower, and improves work efficiency. In addition, the design of the spring 11 makes the fixation more stable and reliable, ensuring the safety and stability of the sound-absorbing board in long-term use.

[0027] Reference Figure 2 and Figure 3 The cleaning component 18 includes a motor 1801, which is fixedly connected to the inside of the right mounting block 17, a reciprocating screw rod 1802 is fixedly connected to the output end of the motor 1801, and a moving block 1803 is threadedly connected to the outside of the reciprocating screw rod 1802, and a cross plate 1804 is fixedly connected to the outside of the moving block 1803, a mounting rod 1805 is fixedly connected to the inside of the cross plate 1804, a cleaning brush 1806 is fixedly connected to the outside of the mounting rod 1805, a guide ring 1807 is fixedly connected to the left side of the outside of the cross plate 1804, a guide rod 19 is fixedly connected to the inside of the left mounting block 17, and the guide ring 1807 is slidably connected to the outside of the guide rod 19.

[0028] When it is necessary to clean the outside of the sound insulation board, it can be achieved by starting the motor 1801. After starting the motor 1801, it will drive the reciprocating screw 1802 fixed at its output end to rotate. As the reciprocating screw 1802 rotates, the moving block 1803 connected to the outside of the reciprocating screw 1802 will also reciprocate outside the reciprocating screw 1802. During the movement of the moving block 1803, it will drive the externally fixed cross plate 1804 to move synchronously. The movement of the cross plate 1804 further drives the internally fixed mounting rod 1805 to move, and the movement of the mounting rod 1805 will drive the externally fixed cleaning brush 1806 to move. Through this design, the cleaning brush 1806 can reciprocate outside the sound insulation board, thereby cleaning the dust and dirt attached to the outside of the sound insulation board, ensuring that the sound insulation board continues to maintain efficient noise suppression performance, and is slidably connected to the outside of the guide rod 19 through the guide ring 1807, which plays a guiding role for the guide ring 1807.

[0029] Working principle: when installing the first sound-absorbing panel 4 and the second sound-absorbing panel 5, first, squeeze the two clamping blocks 13, the two clamping blocks 13 move with the internally rotatably connected adjusting rod 12, the adjusting rod 12 moves with the other end of the two sliders 10 that are rotatably connected to move to both sides outside the fixed rod 9, when the two sliders 10 move, the springs 11 sleeved on both sides of the outside of the fixed rod 9 are squeezed, so that the two springs 11 are deformed under force, and then when the two clamping blocks 13 move to the inside of the mounting tube 8, the mounting tube 8 is inserted into the inside of the second through hole 15, and then, when the two clamping blocks 13 move to the position of the two card slots 16, the two clamping blocks 13 are inserted into the inside of the two card slots 16 under the reaction force of the two springs 11, so that the installation of the sound insulation board is convenient, and there is no need to use a large number of bolts and rivets during installation. The sound insulation board is fixed by nails, which is simple and convenient to operate, saving time and effort. Then, when the outside of the sound insulation board needs to be cleaned, the motor 1801 is started, and the motor 1801 drives the reciprocating screw 1802 fixed at the output end to rotate. The reciprocating screw 1802 rotates and drives the moving block 1803 connected with an external thread to reciprocate on the outside of the reciprocating screw 1802. When the moving block 1803 moves, it drives the externally fixed cross plate 1804 to move synchronously. The movement of the cross plate 1804 drives the internally fixed mounting rod 1805 to move, and the movement of the mounting rod 1805 drives the externally fixed cleaning brush 1806 to move. The dust attached to the outside of the sound insulation board can be cleaned by the reciprocating movement of the cleaning brush 1806, which makes it easy to clean the dust attached to the outside of the sound insulation board, ensuring that the sound insulation board continues to maintain efficient noise suppression performance.
