Description

Technical Field

[0001] The utility model relates to the technical field of spraying dust reduction, in particular to a spraying device. Background Art

[0002] A large amount of dust and particulate matter is often generated during construction, which will cause serious pollution to the surrounding residential environment. In order to reduce the impact on air quality, high-pressure mist piles are used during construction to evenly spray water mist into the air, thereby effectively absorbing and precipitating dust and particulate matter.

[0003] At present, in order to ensure the spraying range, high-pressure mist piles are usually set relatively high. After the high-pressure mist piles have been used for a period of time, they are easily affected by water quality and cause the atomizing nozzles to be blocked. Since the atomizing nozzles are set at the top of the mist piles, the staff need to use scaffolding and other lifting tools to inspect the atomizing nozzles. The whole inspection process is cumbersome and will increase the safety risks of maintenance workers. Therefore, we propose a spray device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A spray device includes a column 1, a support column 2 is arranged above the column 1, and a spray head 3 is installed at the end of the support column 2. The connection mode between the spray head 3 and the water pipe 4 and the spray distance are prior art, which will not be described in detail here. The water pipe 4 is connected to the bottom of the spray head 3, and a receiving groove adapted to the water pipe 4 is opened inside the support column 2. A connecting shaft 5 is fixedly inserted at the bottom end of the support column 2, and the connecting shaft 5 is movably inserted inside the supporting plate 6. The bottom end of the supporting plate 6 is connected to the outer wall of the top end of the column 1, and the two ends of the connecting shaft 5 are symmetrically sleeved with rotating rings 8, and A fixed ring 9 is sleeved on the outer side of the rotating ring 8. When the support column 2 rotates, the connecting shaft 5 and the rotating ring 8 can rotate simultaneously. The outer side of the rotating ring 8 and the inner side of the fixed ring 9 are evenly provided with fixed teeth. Therefore, when the fixed ring 9 is sleeved on the outer periphery of the rotating ring 8, the connecting shaft 5 can be limited. When the fixed ring 9 is no longer sleeved on the outer side of the rotating ring 8, the limitation of the connecting shaft 5 can be released. The side of the fixed ring 9 is connected to a connecting rod 10, and the bottom end of the connecting rod 10 is connected to a slider. The slider is engaged in the inside of the fixed plate 11, and the side of the fixed plate 11 is fixedly connected to the column 1.

[0023] Further, see Figure 4 It can be known that an annular groove is opened inside the support plate 6, and a connecting ring 7 is engaged inside the annular groove. The connecting ring 7 is fixedly sleeved on the outside of the connecting shaft 5. Through the mutual cooperation between the annular groove and the connecting ring 7, the stability of the connecting shaft 5 during rotation can be further guaranteed.

[0024] Further, see Figure 4 It can be known that a cylinder 13 is installed inside the column 1, and the top end of the cylinder 13 is connected through a push plate 14 and a reinforcing rib 15. Connecting grooves are respectively provided at the bottom end of the support column 2 and at positions corresponding to the reinforcing rib 15. The telescopic principle of the cylinder 13 is a prior art and will not be described in detail here. During the spraying process of the sprinkler head 3, the cylinder 13 is able to push the push plate 14 and the reinforcing rib 15 upward so that the top end of the reinforcing rib 15 is embedded in the plug-in groove to realize the reinforcement operation of the column 1 and the support column 2. When the sprinkler head 3 needs to be repaired, the setting of the cylinder 13 can drive the push plate 14 and the reinforcing rib 15 to be lifted down and embedded in the top position of the column 1 to realize the storage of the push plate 14 and the reinforcing rib 15.

[0025] Further, see Figure 4It can be seen that the bottom end of the push plate 14 is symmetrically distributed with guide rods 16, and the interior of the column 1 is provided with a movable groove adapted to the guide rods 16. Through the mutual cooperation of the guide rods 16 and the movable groove, the push plate 14 can be guided to ensure the stability of the push plate 14 during the lifting and lowering process.

[0026] Further, see Figure 4 It can be known that a sliding groove adapted to the slider is opened inside the fixed plate 11, and a spring 12 is connected to the inner wall of the sliding groove, and the other end of the spring 12 is fixedly connected to the slider. When in use, the spring 12 connected inside the sliding groove can effectively ensure the tightness of the fixed ring 9 on the outer periphery of the rotating ring 8.

[0027] Further, see Figure 4 It can be seen that the top of the reinforcing rib 15 is connected to a rubber column, and the top of the rubber column is set as an arc structure. The rubber column set by the arc structure can effectively prevent the top of the reinforcing rib 15 from directly and rigidly contacting the plug-in slot, so as to achieve protection of the reinforcing rib 15.

[0028] Further, see Figure 2 and Figure 3 It can be seen that two groups of connecting rods 10 are distributed on the side of the fixed ring 9, and the two groups of connecting rods 10 are symmetrically distributed about the central axis of the fixed ring 9. Since two groups of connecting rods 10 are distributed on the side of the fixed ring 9, when the fixed ring 9 translates, the sliders connected to the bottom ends of the two groups of connecting rods 10 can slide in the slide grooves inside the fixed plate 11 at the same time, thereby effectively ensuring the smooth movement of the fixed ring 9.

[0029] Working principle: When the utility model is used, the staff can first install the device at a suitable position on the construction site, and then connect the water pipe 4 to the external water supply equipment, so that water can be transported to the inside of the sprinkler head 3 for spraying. When the sprinkler head 3 fails in the spraying state, the staff can first drive the push plate 14 and the reinforcing ribs 15 to move downward as a whole through the cylinder 13, so that the multiple groups of reinforcing ribs 15 are stored in the inside of the column 1. At this time, the staff can pull the two groups of fixing rings 9, so that the slider connected to the bottom end of the connecting rod 10 is inside the fixing plate 11. When the fixing ring 9 is no longer sleeved on the outer side of the rotating ring 8, the restriction on the connecting shaft 5 can be released. At this time, the staff can push the support column 2, so that the connecting shaft 5 connected to the bottom end thereof is forced to rotate inside the support plate 6. After the support plate 6 is rotated 90 degrees, the staff can stop pulling the two sets of fixing rings 9, so that they are again engaged with the outer periphery of the rotating ring 8 through the elastic force of the spring 12, and the rotating ring 8 is limited to fix the connecting shaft 5. Since the height of the rotating sprinkler head 3 is relatively low, it is convenient for the staff to carry out maintenance;

[0030] After the inspection is completed, the staff can pull the two sets of fixing rings 9 again, so that the connecting shaft 5 rotates again and drives the support column 2 to be vertical. At this time, by starting the cylinder 13, multiple sets of reinforcing ribs 15 can be driven to be lifted up and inserted into the plug-in grooves opened inside the support column 2, thereby realizing the reinforcement of the connection process between the column 1 and the support column 2. The above is the entire working principle of the utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0032] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
