Description

Technical Field

[0001] The invention relates to a dust suppression device, in particular to a rotary water spray dust suppression device for construction management of building projects. Background Art

[0002] During construction projects, due to the nature of the work, there is usually a large amount of dust and inhalable particles in the air, which is very harmful to the health of the workers. As the construction site is large, the industry usually uses water spraying to reduce dust, increasing air humidity to absorb dust and reduce the dust content in the air.

[0003] For example, the Chinese patent publication with the announcement number CN208642144U discloses a conveniently movable rotary spray dust reduction device, which includes a spray head, a branch pipe and an angle steel bracket; the spray head is a rotary spray head; the rotary spray head is connected to the top of the branch pipe; the branch pipe is fixedly arranged on the angle steel bracket in the vertical direction and is connected to the connecting pipe; a fixed bracket is also provided at the bottom of the angle steel bracket; the rotatable and movable spray device provided by the utility model has the characteristics of convenient installation, convenient movement, wide dust reduction area, high turnover rate and low cost, etc., but the patent has the following problems:

[0004] First, since the nozzle is fixed at a high place, although increasing the height can cover a larger area, when the nozzle is blocked, it is necessary to climb up to repair and replace it, which is dangerous.

[0005] Second, the nozzle is set at a high place, and the pumped clean water needs to be pressurized to transport the clean water to the nozzle above. When the water pressure is not up to standard, the atomization effect of the nozzle spraying clean water is poor. Summary of the invention

[0006] The object of the present invention is to provide a rotary water spray dust reduction device for construction engineering management to solve the existing problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: A rotary water spray dust suppression device for construction engineering management, comprising a connecting rod, a high rod hinged on the upper end of the connecting rod, the connecting rod comprising a first support rod and a first connecting block, the first connecting block is fixed to the upper end of the first support rod, a bearing is embedded in the first connecting block, the high rod comprises a supporting long rod and a second connecting block, the second connecting block is fixed to the lower end of the supporting long rod, a connecting shaft is fixed in the second connecting block, the connecting shaft is sleeved in the bearing, a snap-on ring is slidably sleeved on the high rod, a pressure limiting pipe is fixed to the upper end of the supporting long rod, a drainage head is fixed on the pressure limiting pipe, the other end of the drainage head is fixed to a rotary sealing joint, a spray head is fixed on the rotary sealing joint, and atomizing nozzles are fixed obliquely around the spray head.

[0008] Preferably, a base is fixedly connected to the lower end of the first support rod.

[0009] Preferably, a support seat is fixedly connected to an outer wall of one side of the first connecting block, a worm is rotatably mounted on the support seat via a bearing seat, and one end of the worm is fixedly connected to a rotating disk.

[0010] Preferably, a worm wheel is fixedly connected to one end of the connecting shaft, and the worm wheel and the worm are meshed with each other.

[0011] Preferably, a limiting hole is provided on one side of the first connecting block near the upper edge.

[0012] Preferably, a threaded sleeve block is embedded in the clamping ring, a fixing bolt is installed in the inner thread of the threaded sleeve block, and the fixing bolt cooperates with the limiting hole.

[0013] Preferably, a limiting groove is provided on an outer wall of one side of the high rod, a limiting protrusion is fixedly connected to the inner wall of the clamping ring, and the limiting protrusion is slidably matched with the limiting groove.

[0014] Preferably, a connector is fixedly connected to the bottom of the pressure-limiting tube, a pumping hose is fixedly connected to the other end of the connector, buckles are fixedly connected to the high rod and the connecting rod, and the pumping hose is clamped in the buckle.

[0019] 2. By setting a piston, the internal passage of the pressure-limiting tube can be blocked. When the water pressure of the clean water is insufficient, the piston cannot be pushed to the left side of the discharge head. When the water pressure is sufficient, the clean water can move the piston to the left side of the discharge head, and then flow into the rotary sealing joint through the discharge head, avoiding the problem of insufficient water pressure being delivered to the atomizing nozzle and failing to atomize and spray the clean water.

[0020] 3. The limiting protrusion and the limiting groove slide together to limit the clamping ring to move up and down, so as to avoid the problem that the position of the threaded sleeve and the limiting hole are misaligned due to the rotation of the clamping ring, making it difficult for the end of the fixing bolt to be screwed into the limiting hole.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1-5 As shown, the present invention has the following specific embodiments.

[0029] Example 1

[0030] A rotary water spray dust suppression device for construction engineering management comprises a connecting rod 1, the upper end of which is hinged with a high rod 2, the connecting rod 1 comprises a first support rod 101 and a first connecting block 102, the first connecting block 102 is fixed to the upper end of the first support rod 101, a bearing 108 is embedded in the first connecting block 102, the high rod 2 comprises a supporting long rod 201 and a second connecting block 202, the second connecting block 202 is fixed to the lower end of the supporting long rod 201, a connecting shaft 203 is fixedly connected in the second connecting block 202, the connecting shaft 203 is sleeved in the bearing 108, a snap-on sleeve 3 is slidably sleeved on the high rod 2, a pressure limiting pipe 4 is fixedly connected to the upper end of the supporting long rod 201, a liquid discharge head 402 is fixedly connected to the pressure limiting pipe 4, the other end of the liquid discharge head 402 is fixedly connected to a rotary sealing joint 502, a nozzle 5 is fixedly connected to the rotary sealing joint 502, and an atomizing nozzle 501 is fixedly connected to the nozzle 5 at an angle around it.

[0031] In this embodiment, the connecting shaft 203 cooperates with the bearing 108 to rotatably connect the long support rod 201 and the first support rod 101, so that the high rod 2 can rotate a certain angle relative to the connecting rod 1. When the spray head and other spray components at the upper end of the high rod 2 are damaged, the high rod 2 can be rotated to lower the height of its end. At this time, the maintenance personnel can repair and replace the damaged components on the ground. The clamping ring 3 is slidably sleeved on the high rod 2. When the high rod 2 is in the vertical state, the clamping ring 3 can slide down to the connection between the long support rod 201 and the first support rod 101. At this time, the clamping ring 3 will clamp the long support rod 201 and the first support rod 101, limiting The high pole 2 rotates to keep the high pole 2 in a vertical state, and the clean water is pumped to the pressure-limiting pipe 4 through a pipeline. The pressure-limiting pipe 4 can transport the clean water to the nozzle 5 through a rotating sealing joint 502. The rotating sealing joint 502 is a common pipeline connection rotating connector, and the upper and lower ends can rotate relative to each other. Two atomizing nozzles 501 are provided, which are fixed on the outer wall of the nozzle 5 along the tangent method of the nozzle 5. The clean water inside the nozzle 5 will be sprayed to the outside through the atomizing nozzle 501. Since there will be a certain reverse thrust when the clean water is sprayed out, the atomizing nozzle 501 will be driven by the reverse thrust to rotate the nozzle 5, so that the device can rotate to spray atomized clean water to reduce dust in the surrounding air.

[0032] Example 2

[0033] like Figure 1 , 2As shown in , 4, a base 103 is fixedly connected to the lower end of the first support rod 101, a support seat 104 is fixedly connected to the outer wall of one side of the first connecting block 102, a worm 105 is rotatably installed on the support seat 104 through a bearing seat, one end of the worm 105 is fixedly connected to a rotating disk 106, one end of the connecting shaft 203 is fixedly connected to a worm wheel 204, the worm wheel 204 and the worm 105 are meshed with each other, a limiting hole 107 is provided at a position near the upper end edge of one side of the first connecting block 102, a threaded sleeve block 302 is embedded in the clamping ring 3, a fixing bolt 303 is installed on the inner thread of the threaded sleeve block 302, the fixing bolt 303 and the limiting hole 107 cooperate with each other, a limiting groove 205 is provided on the outer wall of one side of the high rod 2, a limiting protrusion 301 is fixedly connected to the inner wall of the clamping ring 3, and the limiting protrusion 301 and the limiting groove 205 are slidably matched.

[0034] In this embodiment, the base 103 can be used to fix the device on the ground with a pin, and the rotating disk 106 can be used to drive the worm 105 to rotate. The worm 105 and the worm wheel 204 are meshed with each other, so that the rotation of the worm 105 can drive the worm wheel 204 to rotate. The worm wheel 204 can drive the high pole 2 to rotate through the connecting shaft 203, so as to adjust the angle of the high pole 2. The limiting protrusion 301 and the limiting groove 205 are slidably matched to limit the clamping ring 3 to only move up and down, so as to prevent the rotation of the clamping ring 3 from causing the threaded block 302 and the limiting hole 107 to be misaligned. Tightening the fixing bolt 303 so that its end is screwed into the limiting hole 107 can fix the position of the clamping ring 3, and clamp the supporting long rod 201 and the first support rod 101 together.

[0035] Example 3

[0036] like Figure 1 , 2 As shown in Figures 5 and 6, a connector 401 is fixedly connected to the bottom of the pressure-limiting tube 4, a pumping hose 7 is fixedly connected to the other end of the connector 401, buckles 6 are fixedly connected to the high rod 2 and the connecting rod 1, the pumping hose 7 is clamped in the buckle 6, a telescopic connecting rod 404 is fixedly connected to the pressure-limiting tube 4, a piston 405 is fixedly connected to one end of the telescopic connecting rod 404, a return spring 406 is sleeved on the telescopic connecting rod 404, a convex ring 403 is fixedly connected to the inner wall of the pressure-limiting tube 4, and the convex ring 403 and the piston 405 cooperate with each other.

[0037] In this embodiment, a water pump can be connected through the pumping hose 7 to transport clean water to the connecting head 401, and then the clean water is transported to the inside of the pressure limiting tube 4. The clean water will then squeeze the piston 405 and push the piston 405 to the left. The convex ring 403 cooperates with the piston 405 to limit the movement of the piston 405 to the right side of the connecting head 401, and move the piston 405 to the left side of the drainage head 402. At this time, there is no blockage of the piston 405, and the clean water can flow into the drainage head 402 through the pressure limiting tube 4, and then be transported to the nozzle 5. When the water pressure of the clean water is insufficient, the piston 405 cannot be pushed to the left side of the drainage head 402. At this time, the piston 405 is blocked in the pressure limiting tube 4, and the clean water cannot enter the drainage head 402, thereby avoiding the problem of insufficient water pressure when transported to the atomizing nozzle 501 and the inability to atomize the clean water.

[0038] The working principle and use process of the present invention are as follows: when using the device, it is necessary to place the device in a suitable position, connect the pumping hose 7 to the clean water pumping equipment, and use the pumping hose 7 to pump the clean water into the pressure limiting pipe 4. After the water pressure reaches the standard, the clean water will move the piston 405 to the left side of the liquid discharge head 402, and then use the liquid discharge head 402 to transport the clean water to the nozzle 5 through the rotating sealing joint 502, and then use the atomizing nozzle 501 to spray it to the surrounding area. The atomizing nozzle 501 will be subject to a certain reaction when spraying the clean water. The force drives the nozzle 5 to rotate, so that the atomizing nozzle 501 can rotate to spray clean water. When the component at the upper end of the high pole 2 is damaged and needs maintenance, the fixing bolt 303 can be unscrewed to release the restriction on the clamping ring 3, and the clamping ring 3 can be moved to the supporting long pole 201. At this time, the rotating disk 106 can be used to drive the worm 105 to rotate. The rotation of the worm 105 can drive the high pole 2 to rotate and tilt, so that the height of the upper end of the high pole 2 is reduced, so that the operator can perform replacement and maintenance operations directly on the ground.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
