Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0025] like Figures 1-4As shown, the technical solution adopted by the present invention is as follows: The dust and noise reduction device for power transmission and transformation projects provided by this solution includes a base 1, a protective baffle 2, and a dust reduction component 3. The protective baffle 2 is installed on the upper end of the base 1. The base 1 is provided with fixing holes 7 for installation and fixing to the ground. The dust reduction component 3 is installed on the upper end of the protective baffle 2. The left and right sides of the protective baffle 2 are respectively provided with connecting seats 20 and inserts 21 for assembly. The connecting seats 20 and inserts 21 are fixed by bolts 22. The middle part of the protective baffle 2 is provided with an installation groove. 4. A noise reduction plate 5 is embedded in the mounting groove 4. The noise reduction plate 5 is a noise reduction plate 5 made of sound-absorbing cotton and sound insulation baffle. A protective door 6 is hinged at the front end of the protective baffle 2. Multiple sets of sound-absorbing pads 8 are spaced apart inside the protective door 6. A pin assembly 18 is installed on one side of the front end of the protective baffle 2 through a bracket 17. A pin block 19 is provided on the protective door 6 opposite to the pin assembly 18. The pin assembly 18 and the pin block 19 are engaged and connected. A lighting lamp 24 is installed on the upper end of the protective baffle 2 through a protective cover 23.

[0026] like Figure 5 and Figure 7 As shown, the pin assembly 18 includes an outer sleeve 181 and an inner sleeve 182. The outer wall of the outer sleeve 181 is provided with a limiting protrusion and a first through hole. The inner wall of the pin block 19 is provided with a limiting groove (the limiting groove is a non-through groove) extending axially from the end face. The bracket 17 is provided with a snap-fit ​​hole corresponding to the first hole. The outer sleeve 181 is inserted into the pin block 19 and the bracket 17. The limiting protrusion and the limiting groove abut against each other in both the radial and axial directions, so that the first through hole is aligned with the snap-fit ​​hole. The inner wall of the inner sleeve 182 is fixed with a spring piece. The spring piece is provided with a pin. The inner sleeve 182 is also provided with a second through hole for the pin to pass through. The inner sleeve 182 is inserted into the outer sleeve 181. The pin passes through the first through hole and snaps into the snap-fit ​​hole. By inserting the pin block 19 and bracket 17 into the inner sleeve 181, the protective baffle 2 and the protective door 6 can be initially locked; by inserting the outer sleeve 181 into the inner sleeve 182, the pin is engaged in the snap-fit ​​hole of the bracket 17, making the locking structure between the protective baffle 2 and the protective door 6 more secure and preventing the pin assembly from coming loose during use.

[0027] like Figure 4 and Figure 6As shown, the dust suppression assembly 3 includes a drive chamber 9, a reversible motor 10, a rotating tube 11, and a dust suppression nozzle 12. The drive chamber 9 is located on the top of the protective baffle 2. The reversible motor 10 is located on one side of the drive chamber 9, and the output shaft of the reversible motor 10 extends into the drive chamber 9. The rotating tube 11 is rotatably located on the top of the drive chamber 9, and the lower end of the rotating tube 11 extends into the drive chamber 9. The dust suppression nozzle 12 is mounted on the rotating tube 11. Multiple sets of active bevel gears 13 are spaced apart on the output shaft of the reversible motor 10. The rotating tube 11 is provided with driven bevel gears 14 that are adapted to the active bevel gears 13. The active bevel gears 13 and driven bevel gears 14 mesh with each other. The lower end of the rotating tube 11 is provided with a rotary joint 15, and a water guide pipe 16 is connected to the rotary joint 15. The water guide pipe 16 can be connected to a water tank through a water pump for supplying water spray to the dust suppression nozzle 12.

[0028] In practical use, the device is installed at the power transmission and transformation construction site via the base 1, and the noise reduction plate 5 is installed in the installation groove 4. Together with the sound-absorbing pads 8 set inside the protective door 7, the noise of the power transmission and transformation construction site is reduced.

[0029] When dust suppression is required at the power transmission and transformation construction site, water in the water tank is pumped from the water pipe 16 into the rotating pipe 11 and sprayed out through the dust suppression nozzle 12 to suppress dust. During the dust suppression process, the forward and reverse motor 10 is turned on, so that the rotating pipe 11 drives the dust suppression nozzle 12 to rotate under the meshing of the active bevel gear 13 and the driven bevel gear 14, thereby increasing the dust suppression range of the construction site.

[0030] The lighting lamp 24 can be used for nighttime illumination. The connection seat 20 and the plug block 21 can be used to easily assemble multiple sets of this device. Pulling the pin rod assembly 18 makes the locking between the protective baffle 2 and the protective door 6 more secure. It is also a quick-release structure, which makes it easy to unlock and open the protective door 7 so as to facilitate the disassembly and replacement of the noise reduction plate 5.
