Example
[0027] This embodiment provides a road spray dust suppression device 100, referring to... Figure 1 As shown, it includes a horizontally arranged main water supply pipe 110 and N branch pipes 120 arranged along the length of the main water supply pipe 110. One end of the main water supply pipe 110 forms a closed end 111, and the other end is connected to the water supply pipe 130. A spray head 121 is provided at the end of the branch pipe 120 away from the main water supply pipe 110.
[0028] Among them, such as Figure 2 and Figure 3As shown, the main water supply pipe 110 has an inner pipe 140 inside; the inner pipe 140 has multiple groups of water passage holes, which are spaced apart circumferentially along the inner pipe 140; each group of water passage holes includes multiple water passage holes 141 arranged along the length of the inner pipe 140; the multiple groups of water passage holes include at least one group of fully through water passage holes 142 and at least one group of partially through water passage holes 143. The group of fully through water passage holes 142 contains N water passage holes 141, which correspond one-to-one with the branch pipes 120; the group of partially through water passage holes 143 contains M water passage holes 141 (M < N), which correspond to some of the branch pipes 120. By adjusting the inner pipe 140, the N water passage holes 141 in the group of fully through water passage holes 142 can be selectively aligned with the N branch pipes 120, at which point the N branch pipes 120 are all connected, and the water volume and range of the spray can be maximized. When dust is reduced, the inner pipe 140 can be adjusted to align the M water holes 141 in the non-fully-through water hole group 143 with the M branch pipes 120. These M branch pipes 120 are in a connected state, while the remaining NM branch pipes 120 are in a closed state. In this way, the amount and range of water sprayed can be reduced, thereby achieving the purpose of saving water.
[0029] Furthermore, such as Figure 3 As shown, multiple groups of water passage holes are evenly spaced along the circumference of the inner pipe 140. This allows switching between different groups of water passage holes by rotating a specific angle. The corresponding rotation position can be marked with graduations on the closed end 111 for easy operation. Furthermore, the diameter of the water passage hole 141 is approximately the same as the inner diameter of the branch pipe 120. When adjusting the water flow, the available water passage area can be reduced by offsetting the water passage hole 141 from the branch pipe 120 by a certain area without switching the groups of water passage holes, thereby reducing the overall water flow.
[0030] In this embodiment, there are four groups of water passages, including two groups of fully through water passages 142 and two groups of partially through water passages 143. The two groups of fully through water passages 142 and the two groups of partially through water passages 143 are alternately arranged along the circumference of the inner tube 140. By rotating the inner tube 140 90 degrees around its axis, the group of fully through water passages 142 can be switched to the group of partially through water passages 143. The alternating arrangement allows the operator to switch the groups of water passages regardless of which direction the tube is rotated, making it convenient for the operator.
[0031] Optionally, N=2M, with each alternate branch pipe 120 corresponding to a water passage 141 in the non-fully-through water hole group 143. This arrangement ensures that exactly half of the branch pipes 120 are in a connected state, while the other half are in a closed state, with the connected and closed branch pipes alternating. This reduces water consumption while ensuring a uniform distribution of the spray area.
[0032] Furthermore, such as Figure 1 and Figure 2 As shown, the closed end 111 has a through mounting hole, and the inner tube 140 has a rotating shaft 144 at one end near the closed end 111. The rotating shaft 144 passes through the mounting hole and rotates in conjunction with it. Rotating the rotating shaft 144 can drive the inner tube 140 inside the main water supply pipe 110 to rotate. The power supply for the rotating shaft 144 can be manual or electric.
[0033] As a simple and easy-to-implement solution, the rotating shaft 144 has a through hole 145 at one end located outside the main water supply pipe 110. The through hole 145 extends through the rotating shaft 144 along its diameter, and a rotating handle 146 is movably embedded within the through hole 145. When not in use, the rotating handle 146 can be pulled out from the through hole 145 for separate storage. When in use, the rotating handle 146 can be inserted into the through hole 145 to manually rotate the rotating shaft 144.
[0034] Furthermore, the main water supply pipe 110 and the water supply pipe 130 are connected by a flange. When maintenance is required on the inner pipe 140, the flange connection can be removed to take the inner pipe 140 out of the main water supply pipe 110. During the disassembly and transfer process, the rotating handle 146 can be used as a limiting structure to prevent the inner pipe 140 from coming out. When the main water supply pipe 110 is moved to a safe position, the rotating handle 146 can be removed to take out the inner pipe 140.
[0035] like Figure 1 As shown, branch pipe 120 is located at the top of main water supply pipe 110. A pair of branch pipes 122 are connected to the top of branch pipe 120. The pair of branch pipes 122 extend upward from branch pipe 120 and gradually move away from each other. Spray heads 121 are installed at the top of each pair of branch pipes 120. This arrangement allows for even spraying of water onto both sides of main water supply pipe 110, increasing the coverage area.
[0036] Furthermore, multiple support columns 150 are provided below the main water supply pipe 110, and the multiple support columns 150 are spaced apart along the axial direction of the main water supply pipe 110. The support columns 150 can support the main water supply pipe 110 and prevent it from collapsing.
[0037] In summary, this utility model embodiment provides a road spray dust suppression device 100, which includes a horizontally arranged main water supply pipe 110; an inner pipe 140 is provided inside the main water supply pipe 110; the inner pipe 140 is provided with multiple water passage hole groups, which are spaced apart along the circumference of the inner pipe 140; each water passage hole group includes multiple water passage holes 141 arranged along the length of the inner pipe 140; the multiple water passage hole groups include at least one fully through water passage hole group 142 and at least one non-fully through water passage hole group 143. By rotating the inner pipe 140, the fully through water passage hole group 142 or the non-fully through water passage hole group 143 can be selectively aligned with the branch pipe 120, thereby adjusting the number of water-carrying branch pipes 120 and quickly and easily adjusting the water volume.
[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
