Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a water-saving and recyclable construction site dust suppression spraying device. Background Art

[0002] At present, there are many kinds of dust suppression measures for construction sites. Most of them use closed windbreak walls on the periphery or spray water on vehicles entering and leaving. However, the current water spraying and dust suppression devices simply spray water mist through water guns, and do not make targeted water spraying and dust suppression measures according to the size and loading conditions of the vehicles. It also brings about the problem of waste of water resources.

[0003] For example, in patent CN208792225U, a track-type dust suppression device for construction sites is disclosed, which includes a track, a base, a support frame and a swing mechanism. The dust suppression device is moved quickly and automatically through a PLC controller and a first motor on the surface of the base, and a swing mechanism is provided between the rotating plate and the dust suppression frame to increase the dust suppression area and reduce the labor intensity of the operator. Although the convenience of the dust suppression device is improved, the problem of water resource recovery is also not considered, and its spraying method is also relatively simple.

[0013] Furthermore, the outer wall of the threaded sleeve is smooth and is rotatably connected to the inside of the column.

[0014] Description: Through the stable rotation setting of the threaded sleeve rod, when it rotates relative to the threaded inner rod, it drives the threaded inner rod to slide up and down.

[0015] Furthermore, a sliding block is respectively provided on both sides of the lifting nozzle, and the two sliding blocks are slidably connected to the sliding rails provided inside the two sides of the slot in a one-to-one corresponding manner.

[0016] Note: The setting of the slider ensures the stability of the lifting nozzle during the rising and falling process.

[0017] Furthermore, the rotation range of the rotating nozzle is 90°~120°, and the lifting range of the lifting nozzle is 20~40cm.

By optimizing and adjusting the lifting range of the lifting nozzle, it is ensured that it can repeatedly clean the parts of the vehicle tires where mud is seriously attached.

[0019] Furthermore, the distance between two of the columns is 3-3.5 m.

[0020] Description: By optimizing and adjusting the distance between the two columns, it is ensured that various vehicles can pass between the two columns, thereby completing dust suppression for vehicles entering and leaving the construction site.

[0026] like Figure 1 As shown, a water-saving and recyclable construction site dust suppression spraying device comprises two symmetrically arranged columns 1, a lifting nozzle 2 located in the middle of the column 1, and a rotating nozzle 3 located at the top of the column 1, 6 atomizing nozzles 31 are arranged on the front of the rotating nozzle 3, and a water storage tank 4 is arranged inside the ground outside the bottom of the two columns 1, and the lifting nozzle 2, the rotating nozzle 3 and the atomizing nozzle 31 are all commercially available products;

[0027] like Figure 1 and 2As shown, a slot 11 is provided in the middle of the column 1, and the lifting nozzle 2 slides up and down along the slot 11. A slider 21 is provided on both sides of the lifting nozzle 2, and the two sliders 21 are slidably connected with the slide rails 12 provided inside the two sides of the slot 11 in a one-to-one correspondence. A servo motor 5 is provided on the top of the rotating nozzle 3. The servo motor 5 is a commercially available servo motor. The output shaft at the bottom of the servo motor 5 is connected to the top of the rotating nozzle 3. The two sides of the servo motor 5 are respectively fixedly connected to the top of the column 1 through an L-shaped fixing rod 51. A threaded sleeve rod 6 is provided at the bottom of the rotating nozzle 3. The threaded sleeve rod 6 passes through the column 1 and then extends to the inside of the slot 11. The outer wall of the threaded sleeve rod 6 is smooth and rotatably connected to the inside of the column 1. The outer wall of the threaded inner rod 7 rotatably connected to the top of the lifting nozzle 2 is threadedly rotatably connected to the inner wall of the threaded sleeve rod 6.

[0028] like Figure 1 As shown, the back of the lifting nozzle 2 is connected to the external water source through the first hose 8, a water pump 41 is provided at the bottom of the water storage tank 4, and the backs of the two rotating nozzles 3 are respectively connected to a nearby water pump 41 through a second hose 9. The rotation amplitude of the rotating nozzle 3 is 105°, the lifting amplitude of the lifting nozzle 2 is 30cm, and the distance between the two columns 1 is 3.3m. Example

[0029] The difference between this embodiment and embodiment 1 is that:

[0030] Five atomizing nozzles 31 are arranged on the front of the rotating nozzle 3. The rotation range of the rotating nozzle 3 is 90°. The lifting range of the lifting nozzle 2 is 20 cm. The distance between the two columns 1 is 3 m. Example

[0031] The front of the rotating nozzle 3 is provided with 8 atomizing nozzles 31, the rotation range of the rotating nozzle 3 is 120°, the lifting range of the lifting nozzle 2 is 40cm, and the distance between the two columns 1 is 3.5m;

[0032] A drainage cover plate is provided on the surface of the water storage tank 4.

[0033] Working principle:

[0034] When using the water-saving and recyclable construction site dust suppression spraying device of the utility model, it is generally installed at the gate of the construction site to suppress dust and clean vehicles entering and leaving. When vehicles enter and exit, it is necessary to spray the top of the vehicle with atomization to suppress dust. The water pump 41 is turned on to guide the water in the water reservoir 4 into the rotating nozzle 3 through the second hose 9 and spray it through the atomizing nozzle 31. At the same time, the servo motor 5 is turned on to drive the rotating nozzle 3 to rotate continuously to increase the swing spraying range and improve the dust suppression effect.

[0035] At the same time, the threaded sleeve rod 6 synchronously rotates back and forth and rotates relative to the threaded inner rod 7, driving the threaded inner rod 7 to reciprocate up and down, thereby driving the lifting nozzle 2 to reciprocate up and down. Since the lifting nozzle 2 is rotatably connected to the threaded inner rod 7, when the threaded inner rod 7 rotates and the lifting nozzle 2 moves up and down, the water spraying direction of the lifting nozzle 2 always points to the same direction, that is, the water spraying directions of the two lifting nozzles 2 are opposite, and the slider 21 slides inside the slide rail 12 to keep the lifting nozzle 2 stable, so as to focus on cleaning the parts of the vehicle tires with more mud. When the slider 21 contacts the bottom of the slide rail 12, the threaded inner rod 7 reaches the maximum extension length;

[0036] Since part of the water sprayed by the lifting nozzle 2 does not flush the vehicle tires but directly flows into the water reservoir 4 corresponding to the opposite column 1, the relatively clear water is collected by the water reservoir 4 so as to be stored as water used by the rotating nozzle 3.
