Detailed implementation manners

[0037] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments can all be obtained from commercial channels unless otherwise specified.

[0038] Embodiment: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in the figure, a spraying device for construction safety engineering includes a protective shell 1. Inside the protective shell 1, there is a reciprocating sliding component and a secondary spraying component for spraying the mist up and down. Outside the reciprocating sliding component, there is a pressing and rebounding mechanism for changing the spraying angle. The reciprocating sliding component includes a sliding groove column 20 for rotation and an arc groove 21 for defining the sliding direction. The secondary spraying component includes a transmission column 7 for providing wind power drive and a spray fan 22 for collecting water mist and spraying it secondarily. The rotation of the transmission column 7 drives the spray fan 22 to rotate. The pressing and rebounding mechanism includes several pulleys 36 for sliding along the track of the arc groove 21. At the connection of the pulleys 36, there is a spraying component for expanding the spraying range. The spraying component includes several movable bases 49 for connecting with the pulleys 36 and movable arms 46 for driving the nozzle to move in a fan shape. At the bottom of the movable base 49, there is a rebounding component for driving the spraying component to move reciprocally. The rebounding component includes a second spring 39 for rebounding and resetting. When the movable base 49 moves downward, it squeezes the second spring 39, and the movable base 49 drives the movable arm 46 to move downward in a fan shape. When the second spring 39 rebounds, it drives the movable base 49 to move upward, and the movable base 49 drives the movable arm 46 to make a fan-shaped upward opening movement.

[0039] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown in the figure, during spraying, in the windy state and the operating state of the tower crane, the wind drives the transmission column 7 to rotate. The transmission column 7 drives the spray fan 22 to rotate. The rotation of the transmission column 7 drives the sliding groove column 20 and the arc groove 21 to rotate. The rotation of the sliding groove column 20 drives the arc groove 21 to rotate. The rotation of the arc groove 21 drives the pulley 36 to pull down along the track. The pulley 36 pulling down drives the movable base 49 to pull down. The movable base 49 pulling down drives the movable arm 46 to make a fan-shaped downward movement, so as to concentrate the discharge of the mist. When the pulley 36 pulls down to the rebounding groove on the arc groove 21, it rebounds, and the pulley 36 drives the movable base 49 to rebound and open, so as to expand the spraying area. At the same time, the wind generated by the wind and the rotation of the tower crane is used to change the position of the spray rack 42, solving the problem that the traditional spraying position is fixed and cannot spray in a large range, improving the spraying efficiency. At the same time, through the linked secondary spraying component, when the spray rack 42 contracts, the mist is collected. At the same time, due to the agitation of the spray fan 22, the water vapor collides and merges with each other. After the atomization particles become larger, they are concentrated and sprayed. While spraying in a large range, centralized spraying can be carried out, improving the utilization rate of the mist.

[0044] As Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11When the device is running, one side of the fixed clip 31 close to the protective shell 1 is fixedly connected to the movable base 49. A pressing component is provided at the top of the movable base 49. One side of the connecting column 32 close to the movable base 49 is fixedly connected to the fixed clip 31. One side of the pressing ring 33 close to the fixed clip 31 is fixedly connected to the connecting column 32. The sliding base 34 penetrates through the pressing ring 33 and is fixedly connected to the connecting column 32. One end of the sliding column 35 close to the pressing ring 33 is fixedly connected to the sliding base 34. One side of the pulley 36 close to the sliding base 34 is movably connected to the sliding column 35. During the operation of the device, the circumferential rotation of the chute column 20 drives the circumferential rotation of the arc-shaped groove 21. The circumferential rotation of the arc-shaped groove 21 drives the pulley 36 to slide along the arc-shaped groove 21. Due to the limitation of the arc-shaped groove 21, when driving the pulley 36 to rotate, the pulley 36 is driven to move horizontally downward under the influence of resistance.

At the same time, it is ensured that the pulley 36 will not deviate due to excessive wind force when being pulled down during operation, so that the pulley 36 slides out of the arc-shaped groove 21, resulting in the device being unable to operate. One side of the fixed column 23 away from the internal gear ring 15 is fixedly connected to the load-bearing ring 10. One side of the connecting plate 24 close to the load-bearing ring 10 is fixedly connected to the fixed column 23. The top of the pressing plate 25 is fixedly connected to the connecting plate 24. One side of the pressing chamber 26 close to the connecting plate 24 is fixedly connected to the pressing plate 25. One end of the pressing column 27 close to the pressing plate 25 is movably connected inside the pressing chamber 26. During the downward pulling of the pulley 36, the downward pulling trajectory is fixed, and at the same time, the stability during rebound is improved, avoiding deviation during operation and affecting the operation of the device. The pressing column 27 penetrates through the movable base 49, the load-bearing block 28, and the rebound base 29 and is movably connected to the chute column 20.

The second spring 39 is movably sleeved inside the rebound chamber 30. The bottom end of the second spring 39 is fixedly connected to the extrusion round block 40. When the second spring 39 rebounds, when the spray rack 42 rebounds to the initial position and the movable card 41 collides with the movable card 41 due to the extrusion release of the second spring 39, the spray rack 42 vibrates due to the rebound collision with the movable card 41. The vibration of the spray rack 42 will vibrate and clean the scale and dust attached to the nozzle, solving the problem of nozzle blockage caused by dust and scale, and improving the service life of the device.

[0045] As Figure 12 and Figure 13As shown, the spraying assembly further includes several movable cards 41, several spraying frames 42, several nozzles 43, several movable columns 44, several movable rotating blocks 45, several tension columns 47 and several fixed round blocks 48; one side of the movable card 41 close to the protective shell 1 is fixedly connected to the load-bearing ring 10, one side of the spraying frame 42 close to the protective shell 1 is movably connected to the movable card 41, the bottom end of the nozzle 43 is fixedly connected to the spraying frame 42, the movable column 44 penetrates through the spraying frame 42 and is movably connected to the spraying frame 42, one side of the movable rotating block 45 close to the nozzle 43 is fixedly connected to the movable column 44, one side of the movable arm 46 close to the movable column 44 is fixedly connected to the movable rotating block 45, the tension column 47 penetrates through one end of the movable arm 46 far from the movable rotating block 45 and is movably connected to the movable arm 46, one side of the fixed round block 48 close to the movable arm 46 is fixedly connected to the tension column 47, and one side of the movable base 49 close to the tension column 47 is fixedly connected to the fixed round block 48;

[0046] As Figure 12 and Figure 13 shown, when the rebound bin 30 is pulled down during the operation of the device, it will drive the movable base 49 to be pulled down. The pulling down of the movable base 49 will drive the movable arm 46 to perform a fan-shaped contraction movement downward. The movable arm 46 will pull the spraying frame 42 to perform a fan-shaped contraction movement. The fan-shaped movement of the spraying frame 42 will drive the nozzle 43 to perform fan-shaped up-and-down spraying. When the rebound bin 30 rebounds, it will drive the movable base 49 to rebound. Through continuous up-and-down fan-shaped reciprocating opening and closing spraying, the spraying method is constantly changing. When opening upward from the bottom, a throwing force is applied to the spray, making the spraying range larger. At the same time, when pulled down, the spray will continuously collide and fuse to reduce dust on the low-lying dust.

[0047] Working principle:

[0048] First step: The worker installs the device on the tower crane, connects the water pipe and the device, then connects the equipped high-pressure pump and pipeline, adjusts the device to discharge water, and then connects the quick-release interface on the transmission column 7 to complete the preparation work of the device.

[0049] Second step: When the tower crane is running, the wind force will drive the fan blades 5 to rotate. The fan blades 5 drive the transmission column 7 to rotate. The rotation of the transmission column 7 drives the spraying fan 22 to rotate, avoiding the situation that the high-pressure spray can only change its position through the tower crane at high altitude. The transmission gear 13 is fixedly sleeved on the transmission column 7. The transmission column 7 drives the transmission gear 13 to rotate. The transmission gear 13 drives the first gear 11, the second gear 12 and the third gear 14 to rotate. While rotating, it drives the internal gear ring 15 to rotate. There is a rotating chute inside the protective shell 1. The internal gear ring 15 rotates in the chute, avoiding the loss of wind power transmission and driving the components inside the device more stably and precisely.

[0050] Step 3: The rotation of the internal gear ring 15 drives the rotation of the rotating base 17. The rotation of the rotating base 17 drives the rotation of the chute column 20. The chute column 20 on the chute column 20 drives the pulley 36 to be pulled downwards, causing the rebound bin 30 to move downwards. The downward movement of the rebound bin 30 drives the pressing column 27 to move downwards. The pressing column 27 squeezes the first spring 38 and the extrusion round block 40. When the chute column 20 drives the pulley 36 to be pulled down to the rebound groove on the arc groove 21, the first spring 38 and the extrusion round block 40 rebound to drive the rebound bin 30 to reset. The downward pull of the rebound bin 30 drives the movable base 49 to be pulled down. The downward pull of the movable base 49 drives the movable arm 46 to make a fan-shaped contraction movement downwards. The movable arm 46 pulls the spray rack 42 to make a fan-shaped contraction movement. The fan-shaped movement of the spray rack 42 drives the nozzle 43 to spray up and down in a fan shape. When the rebound bin 30 rebounds, it drives the movable base 49 to rebound and perform a reset spray.

Within the scope of knowledge possessed by those skilled in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention.
