Description

Technical Field

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

[0002] Construction is a critical stage in engineering construction, involving the actual construction process of various types of buildings. This process is often accompanied by a large amount of dust, and dust pollution needs to be controlled with the help of spraying devices. Although the existing dust control technology adopts a multi-angle spraying design to improve the coverage range, it still has significant defects: on the one hand, the traditional water pump directly connected to the water pipe sprinkler mode has a small coverage area, and it takes too long to complete the dust reduction of the entire site, which not only slows down the construction pace, but also affects the overall progress of the project; on the other hand, the current spraying equipment has a rigid structure and cannot flexibly adjust the spray angle and range, making it difficult to adapt to the needs of different construction scenarios. This structural limitation seriously restricts the dust reduction efficiency, and it is especially difficult to meet the high-standard dust prevention requirements of modern large-scale construction sites. Therefore, optimizing the adjustability and coverage capacity of the spraying device has become a key breakthrough in improving the dust reduction efficiency of construction.

[0003] For example, the patent document with the authorization publication number CN221580105U in the prior art provides a construction spraying device; the device is equipped with an adjustment component, a water pump, a guide pipe and a diversion pipe, which can spray out clean water in atomized form for dust removal, with higher dust removal efficiency. The spraying position can be adjusted according to demand, and starting the second motor can drive the threaded rod to move up and down, thereby adjusting the upper and lower positions of the spray. The horizontal rotation of the spray can be adjusted by starting the first motor to increase the spraying range.

[0004] However, the device still has the following problems: While it effectively delivers water through an external flow pipe connecting the water tank, water pump, and rotating block, it also suffers from significant design flaws. When movable components like the movable plate are raised or lowered, the exposed piping is susceptible to tangling, bending, and even pulling and deforming. This not only affects the normal operation and stability of the equipment but can also accelerate pipe aging and damage, ultimately reducing the reliability and service life of the sprinkler. This exposed piping layout urgently needs to be optimized and improved. Summary of the Invention

[0030] A limited rotating seat 54 is fixedly installed in the movable ring 53, and the middle part of the movable rod 42 is rotatably connected to the limited rotating seat 54. An electric push rod 51 is fixedly installed on the upper end of the movable frame 3, and a limited rotating ring 52 is fixedly installed on the upper end of the electric push rod 51 through its output shaft. The movable ring 53 is rotatably installed in the limited rotating ring 52.

[0031] The specific working principle and method of use of the present invention are explained in detail below: When the angle of the rotating block 21 needs to be adjusted, the electric push rod 51 is started, and the movable ring 53 and the movable rod 42 are driven to move upward through its output shaft, so that the first gear block 43 and the first gear sleeve 431 are plugged into each other, and the second gear block 44 and the second gear sleeve 441 are separated from each other. At this time, the second driving motor 4 is started, and the rotating disk 222 is driven to rotate through the plug-in connection between its output shaft and the driving plug rod 45 and the movable rod 42. Under the limitation of the movement direction of the limit slider 221 by the sliding connection between the limit slide rail 22 and the limit slider 221, the rotating rotating disk 222 can be driven to move through the sliding connection between the arc slide groove 223 and the limit slide shaft 224, and then cooperate with the support rod 225 to adjust the angle of the rotating block 21.

[0032] When it is necessary to drive the rotating block 21 to move back and forth, the electric push rod 51 is started, and the movable ring 53 and the movable rod 42 are driven downward by its output shaft, so that the first tooth block 43 and the first gear sleeve 431 are separated from each other, and the second tooth block 44 and the second gear sleeve 441 are plugged into each other. At this time, the second drive motor 4 is started, and the first rotating sleeve 31 and the groove cam 33 are driven to rotate through the plug-in connection between its output shaft and the driving plug rod 45 and the movable rod 42. With the help of the spring 38, the fitting effect between the movable shaft 35 and the inner wall of the groove cam 33 can drive the rack 34 to move back and forth in a straight line, and then the meshing connection between the rack 34 and the second driven gear 36 can drive the second rotating sleeve 32 to rotate back and forth, and then the hollow flow channel plate 2 and the rotating block 21 can be driven to move back and forth.

[0033] When the height of the rotating block 21 needs to be adjusted, the first drive motor 16 is started, and the threaded ring 15 is driven to rotate through the meshing connection between its output shaft and the first driving gear 17 and the first driven gear 18. The limiting tube 13 is connected to the threaded tube 14 through the plug-in connection between the limiting tube 13 and the threaded tube 14 to limit the movement direction of the threaded tube 14. The rotating threaded ring 15 can drive the threaded tube 14 to move up and down through the threaded connection between the limiting tube 13 and the threaded tube 14, thereby achieving the effect of adjusting the height of the hollow flow channel plate 2 and the rotating block 21.

[0034] When water needs to be sprayed, the water pump 12 is started to guide the water inside the water tank 11 into the limiting pipe 13, and then the water is injected into the hollow flow channel plate 2 through the threaded pipe 14, the first rotating sleeve 31, the second rotating sleeve 32 and the movable ring 53 in sequence. Since the hollow flow channel plate 2 is connected to the rotating block 21 through the through hole 214, the hollow flow channel plate 2 can inject water into the rotating block 21, and finally spray it out through the nozzle 210; Among them, sealing gaskets are provided between the limiting tube 13 and the threaded tube 14, between the movable frame 3 and the first rotating sleeve 31, between the first rotating sleeve 31 and the second rotating sleeve 32, between the second rotating sleeve 32 and the movable ring 53, between the hollow flow channel plate 2 and the rotating disk 222, and between the limiting rotating shaft 213 and the limiting rotating hole 212, which can effectively prevent moisture from overflowing.

[0035] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0036] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
