The dust prevention device for construction includes a dust removal component 100 and an adjustment component 200, which cooperate to effectively adjust the air duct 104.

[0029] Specifically, the dust removal assembly 100 includes a support platform 101, a rotating platform 102, a fixed frame 103, an air duct 104 and a fan 105. The rotating platform 102 is arranged on the top of the support platform 101, the fixed frame 103 is located on the rotating platform 102, the air duct 104 is arranged on one side of the fixed frame 103, and the fan 105 is located on the inner side of the air duct 104.

[0030] A water pump and a water tank (not shown in the figure) are provided inside the support platform 101, and a nozzle is provided on the air duct 104, through which atomized water is sprayed out, so that dust can be removed from the construction site. The rotating table 102 is connected to the support platform 101, and the rotating table 102 is used to drive the air duct 104 to rotate, so that dust can be removed from multiple angles. The fixed frame 103 is used to support the air duct 104, and the water mist can be sent to the area where dust removal is required through the fan 105. This is the prior art, and this solution will not be elaborated in detail, and those skilled in the art can clearly understand the working principle.

[0031] Specifically, the adjustment component 200 is arranged on the support platform 101, and includes an adjustment member 201, a fixing member 202, a rotating member 203 and a limiting member 204. The adjustment member 201 is arranged on one side of the fixing frame 103, the fixing member 202 is located on the outside of the adjustment member 201, the rotating member 203 is arranged on one side of the fixing member 202, and the limiting member 204 is located on one side of the fixing member 202.

[0032] The adjusting member 201 is provided to adjust the angle of the air duct 104, and the adjusting process does not require too much time and manpower, so that the air duct 104 can be quickly adjusted to the specified angle, and the adjustment process is more labor-saving and convenient, and then the adjusting member 201 is locked and fixed by the fixing member 202, so that the angle of the air duct 104 can be locked to avoid the situation where the angle of the air duct 104 will change during use. The rotating member 203 is provided to drive the fixing member 202 to move, so that the fixing member 202 releases the restriction on the adjusting member 201 and the air duct 104, and then the angle of the air duct 104 can be adjusted. The limiting member 204 is provided to restrict the rotating member 203, so as to prevent the angle of the air duct 104 from being offset due to accidental touching of the rotating member 203 during operation.

[0033] Example 2

[0034] Reference Figure 1-Figure 5, which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0035] Specifically, the adjusting member 201 includes a fixed sleeve 201a and a movable rod 201b. The fixed sleeve 201a is disposed on the supporting platform 101, and the movable rod 201b is located at one side of the fixed sleeve 201a.

[0036] One end of the fixed sleeve 201a is hinged to the fixed frame 103 through a hinge plate, the movable rod 201b is movably connected to the fixed sleeve 201a, and one end of the movable rod 201b is hinged to the air duct 104 through a hinge plate.

[0037] The fixed sleeve 201a and the movable rod 201b cooperate to support the air duct 104, so as to prevent the angle of the air duct 104 from changing during use. When the angle of the air duct 104 needs to be adjusted, the air duct 104 is moved upward or downward, and the movable rod 201b is driven to slide in the fixed sleeve 201a, so that the angle of the air duct 104 can be adjusted. The adjustment process does not require too much time and manpower, and the air duct 104 can be quickly adjusted to the specified angle. At the same time, the adjustment process is more labor-saving and convenient.

[0038] Specifically, the adjusting member 201 further includes a first spring 201c, and two ends of the first spring 201c are respectively fixed to the inner wall of the fixing sleeve 201a and the movable rod 201b.

[0039] The first spring 201c is provided to apply an upward elastic force to the movable rod 201b, thereby offsetting part of the weight of the air duct 104 that moves downward due to its own weight. When the air duct 104 needs to be adjusted upward, the first spring 201c applies a thrust to the movable rod 201b. At this time, the operator only needs to apply an upward auxiliary force to the air duct 104 to drive the air duct 104 to adjust upward. When the air duct 104 is adjusted downward, the first spring 201c supports the air duct 104 to prevent the air duct 104 from suddenly falling downward. Then the operator applies a downward force to the air duct 104, and the air duct 104 can be easily adjusted downward by its own weight, so that when the angle of the air duct 104 is adjusted, the air duct 104 can be driven to move upward or downward without spending too much force.

[0040] Specifically, the fixing member 202 includes a fixing block 202a and a fixing column 202b, the fixing block 202a is fixed to the outside of the fixing sleeve 201a, the fixing column 202b is located inside the fixing block 202a, and a positioning hole 201b-1 is provided on the movable rod 201b, and the fixing column 202b is engaged with the positioning hole 201b-1.

[0041] The fixed column 202b is movably connected with the fixed block 202a, and the fixed block 202a supports and positions the fixed column 202b to prevent it from shifting during movement. When the fixed column 202b is engaged with the positioning hole 201b-1, the movable rod 201b is locked by the cooperation of the two, so that the movable rod 201b cannot move in the fixed sleeve 201a, thereby locking the angle of the air duct 104, thereby preventing the angle of the air duct 104 from changing during use.

[0042] Specifically, there are multiple positioning holes 201b-1, which are evenly distributed on the movable rod 201b in a straight line.

[0043] The air duct 104 can be locked at different angles by the cooperation of the plurality of positioning holes 201 b - 1 and the fixing columns 202 b .

[0044] Specifically, the rotating member 203 includes a rotating sleeve 203a and a fixed shaft 203b, the rotating sleeve 203a is rotatably connected to the top of the fixed block 202a, the fixed shaft 203b is fixed in the rotating sleeve 203a, a spiral groove 202b-1 is opened on the fixed column 202b, and the fixed shaft 203b slides in the spiral groove 202b-1.

[0045] When the rotating sleeve 203a rotates, it will simultaneously drive the fixed shaft 203b to slide in the spiral groove 202b-1. When the fixed shaft 203b slides downward in the spiral groove 202b-1, the fixed column 202b will move upward relatively, so as to achieve the separation of the fixed column 202b and the positioning hole 201b-1. Then, under the upward thrust of the first spring 201c and the force of the staff on the air duct 104, the fixed column 202b can be easily engaged with different positioning holes 201b-1, and then the air duct 104 can be adjusted to different angles. In this way, when adjusting the angle of the air duct 104, the air duct 104 can be driven to move upward or downward without spending too much force.

[0046] Example 3

[0047] Reference Figure 1-Figure 5 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0048] Specifically, the rotating member 203 further includes a limit block 203c, the limit block 203c is fixed in the fixed block 202a, a limit slot 202b-2 is provided on the fixed column 202b, and the limit block 203c slides in the limit slot 202b-2.

[0049] When the fixed shaft 203b slides in the spiral groove 202b-1, the limit block 203c will slide relatively in the limit groove 203b-2. When the fixed shaft 203b stops sliding, the corresponding limit block 203c will also stop sliding. At this time, the fixed column 202b will be locked together with the limit block 203c to prevent the fixed column 202b from rotating.

[0050] Specifically, the rotating member 203 further includes a handle 203d, and the handle 203d is fixed to one side of the rotating sleeve 203a.

[0051] The handle 203d is provided to connect the rotating sleeve 203a, so that the rotation is faster and more convenient.

[0052] Specifically, the limiting member 204 includes a connecting block 204a and a limiting column 204b, one side of the connecting block 204a is fixed to the rotating sleeve 203a, the limiting column 204b is inserted into the connecting block 204a, a limiting hole 202a-1 is opened on the fixed block 202a, and the limiting column 204b is engaged with the limiting hole 202a-1.

[0053] The connection block 204a is provided to support and position the limiting column 204b, and the limiting column 204b is connected to the rotating sleeve 203a at the same time. When the limiting column 204b is engaged with the limiting hole 202a-1, the rotating sleeve 203a can be locked through the cooperation of the two, so that the rotating sleeve 203a cannot rotate, thereby avoiding the external force from accidentally touching the handle 203d during use, thereby causing the rotating sleeve 203a to rotate without adjusting the angle.

[0054] When the angle of the air duct 104 needs to be adjusted, the limiting post 204b is pulled upward to separate it from the limiting hole 202a-1, thereby releasing the restriction on the rotating sleeve 203a. At this time, the rotating sleeve 203a can be rotated to adjust the angle of the air duct 104.

[0055] Specifically, the limiting member 204 further includes a fixing plate 204c and a second spring 204d. The fixing plate 204c is fixed to the top of the limiting column 204b. Both ends of the second spring 204d are respectively fixed to the fixing plate 204c and the fixing block 202a, and are sleeved outside the limiting column 204b.

[0056] The fixing plate 204c is provided to support and fix the second spring 204d, and a downward force is applied to the fixing plate 204c through the second spring 204d, and the limiting column 204b is driven to move downward through the fixing plate 204c, so that the limiting column 204b and the limiting hole 202a-1 are more firmly engaged to avoid separation of the two.

[0057] During use, when the angle of the air duct 104 needs to be adjusted, first pull the limit column 204b upward to separate it from the limit hole 202a-1 to release the restriction on the rotating sleeve 203a, and then rotate the handle 203d to drive the rotating sleeve 203a to rotate simultaneously.

[0058] When the rotating sleeve 203a rotates, it will simultaneously drive the fixed shaft 203b to slide in the spiral groove 202b-1. When the fixed shaft 203b slides downward in the spiral groove 202b-1, the fixed column 202b will move upward relatively, so as to achieve the separation of the fixed column 202b from the positioning hole 201b-1. Then, under the upward thrust of the first spring 201c and the force of the staff on the air duct 104, when it is necessary to adjust the air duct 104 upward, the first spring 201c is used to apply a thrust to the movable rod 201b. At this time, the operator only needs to apply an upward auxiliary force to the air duct 104 to drive the air duct 104 to adjust upward. When the air duct 104 is adjusted downward, the first spring 201c supports the air duct 104 to prevent the air duct 104 from suddenly falling downward. Then, the operator applies a downward force to the air duct 104, and the air duct 104 can be easily adjusted downward by its own weight.

[0059] Finally, by rotating the rotating sleeve 203a in the opposite direction, the fixing column 202b can be engaged with the positioning hole 201b-1 at the current position, and then the limiting column 204b is engaged with the limiting hole 202a-1. Through the cooperation of the two, the rotating sleeve 203a can be locked so that the rotating sleeve 203a cannot rotate, so that the angle of the air duct 104 can be adjusted quickly, labor-saving and time-saving.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
