For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The following is a further description with reference to the accompanying drawings and specific embodiments: Example 1

[0025] like Figure 1 , Figure 2 , Figure 5 , Figure 7As shown, a dust suppression device for construction that is easy to move and use includes a water storage base 1 and a spraying assembly 2. The water storage base 1 is set as a cylindrical structure, and the upper end is set to be open, so that spray water can be contained in the water storage base 1. At least four universal wheels 12 are set at the lower end of the water storage base 1, and the universal wheels 12 are evenly distributed along the circumference direction of the water storage base 1. At the same time, a push handle is set at the upper end of the water storage base 1, and the water storage base 1 can be controlled to move to any position of the construction site under the push of the staff. The spraying assembly 2 includes a submersible pump 21, an infusion tube 22, a first motor 23, a telescopic device 3 and a spraying mechanism 5. The lower end of the telescopic device 3 is set on the horizontal plate 11 in the middle of the upper end of the water storage base 1, and its own height can be changed according to needs. The first motor 23 is set above the horizontal plate 11 and contacts the telescopic device 3, and can control the regular forward and reverse rotation of the telescopic device 3. The infusion pipe 22 is relatively long and is arranged through the telescopic device 3. The lower end is connected to the submersible pump 21 and the upper end is connected to the spraying mechanism 5. At the same time, the submersible pump 21 is immersed in the spraying water of the water storage base 1. Therefore, under the operation of the submersible pump 21, the spraying water can be delivered to the spraying mechanism 5. The spraying mechanism 5 includes a main pipe 51 and a plurality of nozzles 53 of different lengths. The main pipe 51 is arranged vertically. The plurality of nozzles 53 are arranged on the same side of the main pipe 51 and arranged along the height direction of the main pipe 51. At the same time, the lengths of the plurality of nozzles 53 increase from bottom to top. The type of nozzle 53 can be selected according to actual needs, such as a high-pressure nozzle 53. When the spraying water is delivered to the main pipe 51, it is output from the plurality of nozzles 53. Because the lengths of the plurality of nozzles 53 are different, the spraying water output with the same initial velocity will form a plurality of spray trajectories on the vertical surface. Therefore, a spraying water curtain is formed, that is, the spraying area is increased. Then, the first motor 23 is used to control the telescopic device 3 to drive the spraying mechanism 5 to rotate around the vertical axis, so that dust can be removed by spraying over a larger range. Since the device is easy to assemble and has low cost, multiple devices can be deployed in the same construction site. When dust is raised in a certain area of ​​the site, multiple devices are moved to the area and distributed in different positions. At the same time, multiple devices are continuously supplied with spray water, so that dust removal can be effectively achieved, which changes the current situation of poor mobility of existing dust removal equipment, poor dust removal effect, and increased construction costs.

The sleeve 52 is fixedly connected to the main tube 51, and a second convex plate is provided on the side. A threaded rod 24 is provided through the second convex plate through a bearing connection. The upper end of the threaded rod 24 is connected to the output shaft of the second motor. The threaded rod 24 is threaded through the first convex plate 34. When the second motor is working, the threaded rod 24 can be controlled to rotate. Since the threaded rod 24 is threaded through the first convex plate 34, the lifting tube 32 can be driven to rise and fall, so as to adjust the length of the telescopic device 3 and adjust the height of the spraying mechanism 5, thereby providing convenience for adapting to different working environments and improving the practicality of the device. In order to stably connect the sleeve 52 to the lifting tube 32, a clamping groove 33 is provided at the upper end of the lifting tube 32, and a clamping column is provided in the sleeve 52. The clamping column is located in the clamping groove 33, which enhances the connection strength between the sleeve 52 and the lifting tube 32. At the same time, a through hole is provided at the top of the sleeve 52, and the infusion tube 22 can pass through the through hole to communicate with the main tube 51.

A driving gear is provided on the output shaft of the first motor 23, and a circle of teeth is provided at the lower end of the side wall of the bottom tube 31. The driving gear passes through the notch 19 and meshes with the teeth. When the first motor 23 rotates forward and reverse regularly, the driving gear can control the regular forward and reverse rotation of the bottom tube 31 to provide support for spraying and dust reduction over a larger range.

[0028] like Figure 3 , Figure 5 , Figure 6 , Figure 8 As shown, in order to stably place the bottom tube 31 relative to the limiting tube 17, a first ring plate 18 is provided at the upper end of the limiting tube 17, and a second ring plate 35 is provided at the lower end of the bottom tube 31, the second ring plate 35 is located above the first ring plate 18, and a thrust bearing is provided between the second ring plate 35 and the first ring plate 18, and a fastening mechanism 4 is provided on the outer sides of the first ring plate 18 and the second ring plate 35, and the fastening mechanism 4 includes two groups of limiting frames connected by connecting bolts, each group of limiting frames includes an arc plate 41 connected up and down, and the side walls of the two arc plates 41 close to each other are inlaid with balls 42, and the balls 42 are in rolling contact with the sides of the second ring plate 35 and the first ring plate 18 away from each other. This arrangement can make the bottom tube 31 and the limiting tube 17 stably and movably connected, and at the same time provide convenience for disassembling the bottom tube 31 according to needs, thereby improving the flexibility of the device.

[0029] like Figure 1 , Figure 2 As shown, in order to effectively control the operation of the device, a control box is provided on the water storage base 1, and the control box is electrically connected to the motor. The staff can press the button of the control box to control the forward and reverse rotation of the motor. Example 2

[0030] like Figure 1 , Figure 2 , Figure 5 , Figure 7 As shown, a dust suppression device for construction that is easy to move and use includes a water storage base 1 and a spraying assembly 2. The water storage base 1 is set as a cylindrical structure, and the upper end is set to be open, so that spray water can be contained in the water storage base 1. At least four universal wheels 12 are set at the lower end of the water storage base 1, and the universal wheels 12 are evenly distributed along the circumference direction of the water storage base 1. At the same time, a push handle is set at the upper end of the water storage base 1, and the water storage base 1 can be controlled to move to any position of the construction site under the push of the staff. The spraying assembly 2 includes a submersible pump 21, an infusion tube 22, a first motor 23, a telescopic device 3 and a spraying mechanism 5. The lower end of the telescopic device 3 is set on the horizontal plate 11 in the middle of the upper end of the water storage base 1, and its own height can be changed according to needs. The first motor 23 is set above the horizontal plate 11 and contacts the telescopic device 3, and can control the regular forward and reverse rotation of the telescopic device 3. The infusion pipe 22 is relatively long and is arranged through the telescopic device 3. The lower end is connected to the submersible pump 21 and the upper end is connected to the spraying mechanism 5. At the same time, the submersible pump 21 is immersed in the spraying water of the water storage base 1. Therefore, under the operation of the submersible pump 21, the spraying water can be delivered to the spraying mechanism 5. The spraying mechanism 5 includes a main pipe 51 and a plurality of nozzles 53 of different lengths. The main pipe 51 is arranged vertically. The plurality of nozzles 53 are arranged on the same side of the main pipe 51 and arranged along the height direction of the main pipe 51. At the same time, the lengths of the plurality of nozzles 53 increase from bottom to top. The type of nozzle 53 can be selected according to actual needs, such as a high-pressure nozzle 53. When the spraying water is delivered to the main pipe 51, it is output from the plurality of nozzles 53. Because the lengths of the plurality of nozzles 53 are different, the spraying water output with the same initial velocity will form a plurality of spray trajectories on the vertical surface. Therefore, a spraying water curtain is formed, that is, the spraying area is increased. Then, the first motor 23 is used to control the telescopic device 3 to drive the spraying mechanism 5 to rotate around the vertical axis, so that dust can be removed by spraying over a larger range. Since the device is easy to assemble and has low cost, multiple devices can be deployed in the same construction site. When dust is raised in a certain area of ​​the site, multiple devices are moved to the area and distributed in different positions. At the same time, multiple devices are continuously supplied with spray water, so that dust removal can be effectively achieved, which changes the current situation of poor mobility of existing dust removal equipment, poor dust removal effect, and increased construction costs.

The lower end of the lifting tube 32 is inserted into the bottom tube 31. The upper end of the lifting tube 32 is provided with a sleeve 52 through a connecting bolt connection sleeve. The sleeve 52 is fixedly connected to the main tube 51, and a second convex plate is provided on the side. A threaded rod 24 is provided through the second convex plate through a bearing connection. The upper end of the threaded rod 24 is connected to the output shaft of the second motor. The threaded rod 24 is threaded through the first convex plate 34. When the second motor is working, the threaded rod 24 can be controlled to rotate. Since the threaded rod 24 is threaded through the first convex plate 34, the lifting tube 32 can be driven to rise and fall, so as to adjust the length of the telescopic device 3 and adjust the height of the spraying mechanism 5, thereby providing convenience for adapting to different working environments and improving the practicality of the device. In order to stably connect the sleeve 52 to the lifting tube 32, a clamping groove 33 is provided at the upper end of the lifting tube 32, and a clamping column is provided in the sleeve 52. The clamping column is located in the clamping groove 33, which enhances the connection strength between the sleeve 52 and the lifting tube 32.
