Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a wall sprayer. Background Art

[0002] During the construction process, a large amount of dust will be generated at the construction site, which will have an impact on the environment. In order to meet environmental protection standards, it is usually necessary to build a wall in the construction area and then install a sprayer on the top of the wall to spray dust in the construction area.

[0003] The existing sprayer pumps out water through a high-pressure water pump, installs multiple atomizing nozzles on the top of the fence, and connects the water pump and the atomizing nozzles through water pipes. The nozzles are usually installed at intervals of 2-3 meters. When the fence is long and there are many nozzles, the water pressure of the nozzles far away from the water pump will be lower, affecting the dust reduction effect of the nozzles far away from the water pump. The existing solution usually installs the water pump in the middle of the water pipe, and the water flow will flow to both sides of the pipe, or adds a booster pump in the middle of the water pipe to increase the water pressure and ensure that the spray volume of multiple nozzles is relatively close. However, since the length of the construction fence is relatively long, the construction area is constantly advancing. If the water pump or booster pump is installed in the middle of the water pipe, then when the construction reaches the middle area of the water pipe, the construction will be stopped, and the water pump or booster pump will be moved or disassembled, affecting the construction of the construction site. For this reason, we propose a wall sprayer. Summary of the Invention

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-9 , the present invention provides a technical solution:

[0029] Example 1:

[0030] A wall sprayer, comprising:

[0031] Pipe 2, a plurality of nozzles 1 for spraying air outside the wall are provided at equal intervals on the outside of the pipe 2;

[0032] The regulating mechanism 3 is located between every two adjacent nozzles 1 and controls the water pressure and water volume of the water mist sprayed by the nozzles 1 .

[0033] The pipeline 2 includes multiple water pipe units 21 connected end to end in sequence, and the nozzle 1 is installed on one side of each water pipe unit 21 in sequence. One end of the water pipe unit 21 is provided with an external thread, and the side of the water pipe unit 21 away from the external thread is provided with an internal thread. The external thread and the internal thread of the pipeline 2 cooperate with each other, which can facilitate the docking between adjacent pipelines 2. The docking is relatively convenient and is convenient for straight walls in construction.

[0034] The adjusting mechanism 3 includes an adjusting plate 30 installed in the water pipe unit 21. The adjusting plate 30 is provided with a through hole 1 31 for water to flow through. The surface of the water pipe unit 21 is provided with a through hole 2 32 corresponding to the through hole 1 31. The nozzle 1 is installed on the outside of the through hole 2 32 of the water pipe unit 21. The nozzle 1 is fixedly connected to the water pipe unit 21. Both ends of the adjusting plate 30 are slidingly connected to the inner wall of the water pipe unit 21. One end of the adjusting plate 30 is fixedly connected to an extrusion ring 33. The extrusion ring 33 is located on the inner wall of the water pipe unit 21. The other end of the adjusting plate 30 is fixedly connected to a support ring 34. A push ring 35 is provided on one side of the support ring 34. A spring 1 36 is provided between the push ring 35 and the support ring 34. Both ends of the spring 1 36 are fixedly connected to the push ring 35 and the support ring 34 respectively. The extrusion ring 33 extends to the outside of the water pipe unit 21.

[0035] The outer side of the water pipe unit 21 on the side away from the water pump is threadedly connected to a sealing sleeve 37. The sealing sleeve 37 seals the end of the water pipe unit 21 on the side farthest from the water pump, thereby facilitating the sealing of the water pipe unit 21. The inner wall of the water pipe unit 21 close to the water pump is threadedly connected to an abutment ring 38. The abutment ring 38 contacts the outer side surface of the push ring 35, thereby limiting the movement of the push ring 35 when the next water pipe unit 21 is docked, thereby facilitating the next push ring 35 to push the previous extrusion ring 33.

[0036] The above embodiment has the following implementation process. When the staff needs to install the pipe 2 on the wall, the staff will connect the multiple water pipes front and back in sequence, and the external thread of the previous pipe 2 is threadedly connected with the internal thread of the next pipe 2. At this time, the next pushing ring 35 will squeeze the previous squeezing ring 33. When the squeezing ring 33 is squeezed, it will push the adjusting plate 30 to move backward, and then the through hole 1 31 and the through hole 2 32 are misaligned. The overlapping area of the through hole 1 31 and the through hole 2 32 is reduced, and the amount of water entering the sprinkler 1 can be reduced, so that the water pressure and water volume of the water flow in the multiple sprinkler heads 1 are adjusted to be close to each other, and the sprinkler heads 1 of the entire wall can spray atomized water vapor more evenly. In addition, when the wall is extended, it can be directly Connecting the subsequent water pipe unit 21 at the tail is relatively simple to operate. When the spraying position of the fence needs to be changed due to the extension of the fence, it is only necessary to remove the water pipe unit 21 connected to the water pump and install it at the tail, and then use a longer hose 45 to directly connect it to the water pipe unit 21 closest to the water pump, thereby facilitating the spraying of the entire fence. In addition, there is no need to add a pressure pump in the middle of the pipeline 2, nor is there any need to move the water pump to the middle of the pipeline 2, which saves manpower, does not hinder construction, and is convenient for use on construction sites. When a water pipe unit 21 is not connected, the flow area of the water flow between the through hole 1 31 and the through hole 2 32 of all water pipe units 21 is automatically adjusted relatively, thereby ensuring that the injection pressure of multiple nozzles 1 is relatively close.

[0037] According to the above embodiment, embodiment 2,

[0038] The regulating mechanism 3 includes a connecting cover 51 connected between the nozzle 1 and the pipe 2. The connecting cover 51 is hollow and connects the pipe 2 and the nozzle 1. The interior of the connecting cover 51 is slidably connected to a sealing plate 1 52. The interior of the connecting cover 51 is fixedly connected to a sealing plate 2 53 that fits the sealing plate 1 52. A rack 1 54 is provided on the top of the sealing plate 1 52. The rack 1 54 is fixedly connected to the sealing plate 1 52. A gear 1 55 is provided on the top of the rack 1 54. The gear 1 55 is fixedly connected to the sealing plate 1 52. The outer side is connected to gear 2 56 through a rotating shaft, and the rotating shaft is rotatably connected to the connecting cover 51. The two ends of the rotating shaft are fixedly connected to gear 1 55 and gear 2 56 respectively. A rack 2 57 is provided at the bottom of gear 2 56. Rack 2 57 is slidably connected to the connecting cover 51. One side of rack 2 57 is connected to the connecting cover 51 through spring 2 58. The two ends of spring 2 58 are fixedly connected to rack 2 57 and the connecting cover 51 respectively. A wire rope 59 is connected between two adjacent racks 2 57.

[0039] One end of the rack 2 57 is fixedly connected to the wire rope 59 , and the end of the wire rope 59 is fixedly connected to a hook 6 . The other end of the rack 2 57 is fixedly connected to a hanging ring 7 , and the hook 6 can be hooked on the hanging ring 7 .

[0040] The above embodiment has the following working process. When the wall is bent, at this time, the pipe 2 directly adopts the hose 45, and the nozzle 1 is directly fixedly connected to the pipe 2. After the pipe 2 and the nozzle 1 are installed on the wall, at this time, the nozzle 1 close to the water pump is set as the previous nozzle 1, and the next nozzle 1 close to the water pump nozzle 1 is set as the next nozzle 1. After pulling the wire rope 59 of the previous nozzle 1, the wire rope 59 of the next nozzle 1 is hung on the hanging ring 7 of the next nozzle 1. At this time, the wire rope 59 will pull the rack 2 57 to move, the spring 2 58 will stretch, and the rack 2 57 will drive Gear 2 56 rotates, and when it rotates, gear 1 55 is pulled to rotate. Gear 1 55 pulls sealing plate 1 52 to move through rack 1 54. Sealing plate 1 52 reduces the area of water flowing through the interior of connecting cover 51, thereby reducing the amount of water flowing into connecting cover 51, thereby reducing the injection speed and injection amount of the previous nozzle 1. Sealing plate 1 52 of the next nozzle 1 abuts against the inner wall of connecting cover 51. The pipe 2 between the previous nozzle 1 and the next nozzle 1 generates resistance to the water flow. The water flow area in the protective cover of the next nozzle 1 is increased, which makes it easier for the water to flow from the next nozzle. The water flows out of the nozzle 1, thereby reducing the influence of resistance on the nozzle 1. The soft pipe 2 is more convenient for construction workers to use. When encountering a bend in the pipe 2, the construction workers can be more aware of the angle of the bend of the pipe 2, so as to wrap the wire rope 59 at the bend around the outside of the pipe 2 and then connect the hook 6. Since the pipe 2 is in a bent state, the water flow in the pipe 2 at the bend is subject to greater resistance, which can be further offset by winding the wire rope 59, thereby making it convenient to control the water spraying speed and amount of multiple nozzles 1. In addition, during construction, the workers' construction position The placement is gradually advanced. For example, road construction is completed in sections, and buildings are also demolished in sections. Therefore, the amount of dust at different positions of the wall is different. The staff can be more aware of the construction position, so as to remove the wire rope 59 at the construction position from the hanging ring 7, and wrap the wire rope 59 in the unused area around the pipe 2 half a circle, thereby making the area of the sealing plate 52 and the protective cover in the construction area larger, and the water flow will be concentrated at the nozzle 1 in the construction area, and the water mist spraying is more concentrated, which is convenient for timely removal of dust in the air and more convenient for the construction.

[0041] According to the above embodiment, embodiment three,

[0042] A compensation mechanism 4 for adjusting the pressure of the regulating mechanism 3 is provided on the outside of the connecting cover 51 near the water pump. The compensation mechanism 4 includes a compensation cylinder 41 installed on the outside of the connecting cover 51. A piston 42 is provided in the compensation cylinder 41. The piston 42 is slidably connected to the compensation cylinder 41. The end of the piston 42 is fixedly connected to an extrusion rod 43. A spring 44 is provided between the piston 42 and the compensation cylinder 41. The two ends of the spring 44 are fixedly connected to the piston 42 and the compensation cylinder 41 respectively. The compensation cylinder 41 is connected to the pipeline 2 through a hose 45.

[0043] A trigger switch 46 is fixedly connected to one side of the compensation cylinder 41 , and the trigger switch 46 is located on one side of the piston 42 .

[0044] The above embodiment has the following implementation process. When the indoor voltage is unstable or the water pump fails, the water pressure pumped out by the water pump is relatively high. At this time, the high pressure will be directly transmitted to the water flow in the pipe 2. The water flows directly into the compensation cylinder 41 through the hose 45. The pressure in the compensation cylinder 41 increases, and the piston 42 in the compensation cylinder 41 will pull the spring three 44 to stretch. The piston 42 will move toward the trigger switch 46. When the water pressure of the water pump is greater than the limit value that the nozzle 1 and the pipe 2 can withstand or when the water pump is overloaded under high voltage, the piston 42 will squeeze the trigger switch 46, thereby stopping the water pump and causing the distribution box to alarm, requiring staff to come and troubleshoot the problem. It is more intelligent and convenient for the safe use of the entire sprayer.

[0045] When the voltage in the urban area is changed or the water pump is blocked by an obstruction, the water pressure of the water pump is insufficient, the water pressure in the hose 45 connecting the compensation cylinder 41 and the pipe 2 is reduced, and the spring three 44 will recover. When recovering, the spring three 44 will push the piston 42 to move, and the piston 42 drives the extrusion rod 43 to move. The extrusion rod 43 will squeeze the rack two 57, and then the sealing plate one 52 will reduce the area of the water flow through the protective cover, thereby ensuring the water pressure in the entire pipe 2, thereby ensuring that the nozzle 1 can spray mist, ensuring the normal use of the nozzle 1, and reducing the possibility of the nozzle 1 dripping due to insufficient water pressure or the nozzle 1 being covered and blocked by dust in the environment.
