DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides a technical solution: a dust suppression device for construction engineering, comprising a base 1, a water storage mechanism 4 and a lifting mechanism 7, a roller 2 is installed under the base 1, and a handrail 3 is connected to the base 1, a water storage mechanism 4 is installed on the base 1, and a hose 5 is connected to the water storage mechanism 4, a support column 6 is installed on the right side of the water storage mechanism 4, and a lifting mechanism 7 is installed on the support column 6, an angle adjustment mechanism 8 is installed on the lifting mechanism 7, and a nozzle 9 is connected to the angle adjustment mechanism 8.

[0022] The water storage mechanism 4 consists of a water tank 401, a water inlet 402 and a water outlet 403. The water tank 401 is a rectangular hollow structure, and the water inlet 402 is installed on one side of the top of the water tank 401, the water outlet 403 is installed on the right side of the water inlet 402, and a hose 5 is connected to the water outlet 403. The installation of the water storage mechanism 4 ensures sufficient water source during dust reduction.

[0023] The lifting mechanism 7 is composed of a supporting shell 701, a handle 702, a first rotating shaft 703, a first bevel gear 704, a second bevel gear 705 and a threaded rod 706. The supporting shell 701 is installed on the outside of the supporting column 6, and the shape of the supporting shell 701 is opposite to that of the supporting column 6. A handle 702 is installed on the outside of the supporting shell 701, and the handle 702 passes through the supporting shell 701 and is connected to the first rotating shaft 703 to form a rotating structure. The handle 702 allows the lifting mechanism 7 to be manually adjusted, thereby making it more energy-efficient to adjust the height during dust reduction.

[0024] A first bevel gear 704 is installed on the first rotating shaft 703 in the lifting mechanism 7, and the first bevel gear 704 is laterally meshed with the second bevel gear 705 at the bottom. A threaded rod 706 is connected to the second bevel gear 705 at the bottom, and the threaded rod 706 is threadedly connected to the threaded sleeve installed inside the support column 6. The threaded rod 706 is connected to the first bevel gear 704 through the second bevel gear 705 to form a rotating structure. The installation of the lifting mechanism 7 can adjust the height when dust reduction is performed, which is convenient for dust reduction in different environments and improves the dust reduction efficiency.

[0025] The angle adjustment mechanism 8 is composed of a connecting plate 801, a second rotating shaft 802, a gear 803, a cylinder 804 and a rack 805. The connecting plate 801 is installed at the top of the supporting shell 701, and the connecting plate 801 is installed symmetrically up and down. The second rotating shaft 802 is installed at the center of the connecting plate 801, and a gear 803 is installed in the middle of the second rotating shaft 802 to form a rotating structure. The cylinder 804 is installed at one side of the gear 803, and the cylinder 804 is fixedly installed on the connecting plate 801. A rack 805 is connected to the front of the cylinder 804 to form a telescopic structure, and the rack 805 is meshed with the gear 803 to form a rotating structure. The angle adjustment mechanism 8 can adjust the angle change of the nozzle 9.

[0026] Working principle: When using the dust suppression device for construction projects, the staff first holds the handrail 3 and uses the roller 2 to move the dust suppression device to the position where dust suppression is required, and then uses the hose 5 in the water outlet 403 to send water from the nozzle 9 to suppress dust. When the height of dust suppression needs to change, turn the handle 702, and the rotation of the handle 702 drives the first rotating shaft 703 to rotate. Since the first bevel gear 704 is installed on the first rotating shaft 703, and the first bevel gear 704 rotates and meshes with the second bevel gear 705, when the first rotating shaft 703 is rotated, the first bevel gear 704 rotates and meshes with the second bevel gear 705. When the shaft 703 rotates, it will drive the first bevel gear 704 to rotate at the same time, and then the first bevel gear 704 will drive the second bevel gear 705 to rotate. Since the second bevel gear 705 is connected to the threaded rod 706, and the threaded rod 706 is threadedly connected to the threaded sleeve in the support column 6, when the second bevel gear 705 drives the threaded rod 706 to rotate, the threaded rod 706 and the threaded sleeve are threadedly slid, so that the threaded rod 706 drives the support shell 701 to move upward, and then the nozzle 9 installed on the support shell 701 can complete the height adjustment.

[0027] When the angle of the nozzle 9 needs to be adjusted, the cylinder 804 is started. Since the rack 805 is connected to the front of the cylinder 804, when the rack 805 moves with the cylinder 804, the rack 805 engages with the gear 803 installed on the second rotating shaft 802, so that the second rotating shaft 802 rotates. Since the second rotating shaft 802 is connected to the connecting plate 801 above and below, and the nozzle 9 is installed on the top connecting plate 801, when the second rotating shaft 802 drives the connecting plate 801 to rotate, it will also drive the nozzle 9 to rotate, thereby making the nozzle 9 complete the angle change. Since the connecting plate 801 connected by the bearing below the second rotating shaft 802 is fixedly connected to the top of the supporting shell 701, the second rotating shaft 802 only drives the connecting plate 801 installed on the top to rotate. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
