Description

Technical Field

[0001] The utility model belongs to the field of construction site dust reduction equipment, in particular to a fog cannon machine for green construction. Background Art

[0002] A large amount of dust is generated during the construction process at the construction site, and a large number of construction sites are located near residential areas. The dust on the ground is blown into the atmosphere by wind, human and other forces, which is an open pollution source and will form an important part of the total suspended particulate matter in the ambient air, causing serious impact on the surrounding environment. At present, fog cannons are often used for dust reduction at construction sites. The tiny artificial fog particles sprayed by the fog cannon can float in the air for a long time. The fog produced by a single nozzle can reach a length of 3-5 meters and a width of 1-2 meters. The dust particles in the urban atmosphere and factory buildings can be reduced by gravity. The fog particles formed by artificial fog are covered, and the particles fall due to their own weight and cannot be raised again. At the same time, the humidity in the air can be guaranteed without stagnating water, creating a healthy and pleasant living environment, and ensuring that people breathe fresh and pure air during their work and life. When the existing fog cannon moves on the construction site, due to the unevenness of the construction site, the lower surface of the fog cannon is easy to conflict with the ground, and the universal wheels on the lower surface of the fog cannon cannot move.

[0003] The Chinese utility model patent with the publication number CN214513471U discloses a fog cannon for green construction. The fog cannon body is installed on the base by setting a base. A mounting column is fixedly connected to both ends of the side walls of the base. A mounting hole is provided on the lower surface of the mounting column. A mounting rod is slidably connected in the mounting hole. A universal wheel is fixedly connected to one end of the mounting rod. A positioning mechanism for positioning the mounting rod in the mounting hole is provided on the mounting column. A supporting mechanism for facilitating the operator to support the base is provided on the end surfaces at both ends of the base. The base is supported by the supporting mechanism, and the mounting rod slides out of the mounting rod. The mounting rod is positioned in the mounting hole by the positioning mechanism. The universal wheel is pressed against the ground. With such a setting, the structure is simple and the operation is convenient, which facilitates the operator to move the fog cannon on the construction site. However, the device still has some other problems, for example, the working range of the fog cannon is small and the practicality is low. Utility Model Content

[0070] In the present technical solution, in order to facilitate the support of the fog cannon body 300, a support structure 200 is arranged on the mounting base 100, and the support frame 210 of the support structure 200 is fixedly arranged on both sides of the upper surface of the mounting base 100, and a fixed shaft 220 is arranged on the side where the two support frames 210 are close to each other, and an arc plate 230 is arranged between the two fixed shafts 220, and the arc plate 230 is hinged to the fixed shaft 220. The fog cannon body 300 is installed on the arc plate 230, and an adjustment mechanism 240 is arranged below the fog cannon body 300. The height of the fog cannon body 300 can be changed by adjusting the structure, so that the hinge between the arc plate 230 and the fixed shaft 220 can change the angle of the fog cannon body 300, thereby changing the spray angle of the fog cannon body 300.

[0071] This embodiment provides a fog cannon for green construction, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0072] like Figure 1-Figure 4 As shown, in this embodiment, the adjustment mechanism 240 includes:

[0073] The cylinder 241 is fixedly mounted on the upper surface of the mounting base 100;

[0074] A connecting rod 242 is disposed on the output shaft of the cylinder 241;

[0075] A connecting shaft 243 is disposed transversely at the top of the connecting rod 242;

[0076] The connecting plate 244 is fixedly disposed below the fog cannon body 300;

[0077] The rotating seat 245 is fixedly disposed on a side of the connecting plate 244 close to the mounting base 100 , and the connecting shaft 243 is hinged inside the rotating seat 245 .

[0078] In the present technical solution, in order to facilitate changing the angle of the fog cannon body 300, an adjustment mechanism 240 is provided for this purpose. The cylinder 241 of the adjustment mechanism 240 is fixedly mounted on the mounting base 100. A connecting rod 242 is fixedly connected to the output shaft of the cylinder 241. A connecting shaft 243 is fixedly arranged above the connecting rod 242. A rotating seat 245 is hingedly connected to the connecting shaft 243. The rotating seat 245 is fixedly arranged on a connecting plate 244. The connecting plate 244 is fixedly connected to the bottom of the fog cannon body 300. In this way, the height of the connecting rod 242 is driven by the cylinder 241, so that the connecting plate 244 can be driven to change the height of one end of the fog cannon body 300, so that the angle between the fog cannon body 300 and the mounting base 100 is further changed by hinged connection between the fixed shaft 220 and the arc plate 230, and finally the spray angle of the fog cannon body 300 can be changed.

[0079] This embodiment provides a fog cannon for green construction, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0081] In the present technical solution, in order to facilitate the coordinated use between the sliding plate 470, the elastic rope 460 and the elastic cloth 440, the depth of the sliding groove 310 is extended to the position of the elastic cloth 440, and the elastic rope 460 is set at a distance of 3-5CM from the elastic cloth 440. In this way, when the sliding plate 470 slides to the bottom of the sliding groove 310, the elastic rope 460 can be fixed on the side of the sliding plate 470 away from the elastic cloth 440, so that when the sliding plate 470 changes its position, it can drive the elastic rope 460 to deform. Finally, after the elastic rope 460 is pulled to a certain position, it detaches from the gap of the sliding plate 470, so that the elastic rope 460 can generate elastic force on the elastic cloth 440, so that the elastic cloth 440 can be cyclically thrust, thereby continuously extending the range of the fog cannon body 300.

At the same time, a water inlet hole 110 is opened on the mounting base 100 close to the adjusting mechanism 240, and a plug 120 is arranged on the water inlet hole 110. Water can be injected into the cavity in the mounting base 100 through the water inlet hole 110, thereby providing a continuous water source to the fog cannon body 300.
