[0044] An arm-lifting mechanism is arranged on the mounting plate 2, the arm-lifting mechanism can drive the mounting base 9 to ascend or descend, and the movement track of the arm-lifting mechanism is arc-shaped.

[0045] A lifting mechanism is arranged on the mounting plate 2, the lifting mechanism can drive the mounting base 9 to move away from or close to the mounting plate 2 when the arm-lifting mechanism is actuated, so as to drive the water faucet 17 to move away from or close to the mounting plate 2.

[0046] A rotating wheel mechanism is further arranged on the mounting plate 2, the rotating wheel mechanism is fixedly connected with the water faucet 17 through a water pipe, and the rotating wheel mechanism can control the water pipe to elongate or shorten when the lifting mechanism is actuated.

[0047] In this embodiment, the mounting plate 2 is moved by moving the transport vehicle 1, so as to move the spraying dust-settling device to the position below the bent cap that needs dust-settling. The arm-lifting mechanism drives the mounting base 9 to ascend along the arc-shaped track, at the same time, the arm-lifting mechanism drives the lifting mechanism to actuate, and the lifting mechanism drives the mounting base 9 to move away from the mounting plate 2. The height of the water faucet 17 and the angle during spraying can be adjusted through the cooperation of the arm-lifting mechanism and the lifting mechanism, so that the range of the water faucet 17 is completely covered to the bent cap.

[0048] In the process of the faucet 17 rising, the rotating wheel mechanism is driven by the lifting mechanism to extend the length of the water pipe, so that the stable connection between the water pipe and the faucet 17 can be avoided from being damaged due to the pulling force caused by the faucet 17 rising.

[0049] As a further scheme of the utility model, the second rotating shaft 12 and the fourth rotating shaft 15 are rotatably installed on the mounting plate 2, the second telescopic sleeve column 8 is rotatably installed on the second rotating shaft 12, and the second telescopic column 801 is slidably embedded in the second telescopic sleeve column 8; the first telescopic sleeve column 7 is rotatably installed on the fourth rotating shaft 15, and the first telescopic column 701 is slidably embedded in the first telescopic sleeve column 7; the first telescopic column 701 and the second telescopic column 801 are fixedly connected with the mounting base 9.

[0050] In this embodiment, the first telescopic sleeve column 7 can rotate on the fourth rotating shaft 15, and the second telescopic sleeve column 8 can rotate on the second rotating shaft 12; when the first telescopic sleeve column 7 is rotated, the mounting base 9 is driven to rotate by the first telescopic column 701, so that the second telescopic column 801 is driven to rotate, so that the second telescopic sleeve column 8 is rotated, that is, the first telescopic sleeve column 7 and the second telescopic sleeve column 8 are synchronously rotated.

[0051] When the second telescopic column 801 slides in the second telescopic sleeve column 8, the first telescopic column 701 is synchronously slid in the first telescopic sleeve column 7 by the mounting base 9.

[0052] As a further scheme of the utility model, the lifting arm mechanism comprises a motor 3 fixedly installed on the mounting plate 2, an output end of the motor 3 is fixedly connected with a main rotating shaft 4, and the main rotating shaft 4 is rotatably installed on the mounting plate 2; a screw rod column 401 is fixedly installed on the main rotating shaft 4, and an internally-threaded sleeve 5 is threadedly connected with the screw rod column 401; a connecting rod 6 is rotatably installed on the first telescopic sleeve column 7 at an end away from the internally-threaded sleeve 5.

[0053] In this embodiment, when the motor 3 is started, the main rotating shaft 4 is driven to rotate, so that the screw rod column 401 is driven to rotate; through the thread cooperation between the screw rod column 401 and the internally-threaded sleeve 5, the internally-threaded sleeve 5 is driven to move close to or away from the first telescopic sleeve column 7.

[0054] When the internally-threaded sleeve 5 moves close to the first telescopic sleeve column 7, the internally-threaded sleeve 5 pushes the first telescopic sleeve column 7 to rotate through the connecting rod 6. The included angle between the connecting rod 6 and the internally-threaded sleeve 5 gradually increases, and the included angle between the connecting rod 6 and the first telescopic sleeve column 7 gradually decreases. The first telescopic sleeve column 7 is pushed to rotate to drive the second telescopic sleeve column 8 to synchronously rotate, so that the mounting base 9 is lifted along an arc-shaped track.

[0055] As a further scheme of the utility model, the lifting mechanism comprises a first rotating shaft 11 rotatably installed on the mounting plate 2; a worm wheel 10 is fixedly installed on the first rotating shaft 11; a worm 402 matched with the worm wheel 10 is fixedly installed on the end of the screw column 401 away from the motor 3; the first rotating shaft 11 and the second rotating shaft 12 are connected through a belt; a third rotating shaft 13 is rotatably installed on the second telescopic sleeve column 8; the third rotating shaft 13 and the second rotating shaft 12 are connected through a belt; a gear 14 is fixedly installed on the third rotating shaft 13; a rack groove 802 engaged with the gear 14 is formed in the second telescopic column 801.

[0056] In this embodiment, when the main rotating shaft 4 drives the screw column 401 to rotate, the screw column 401 drives the worm 402 to rotate, and through the engagement of the worm 402 and the worm wheel 10, the worm wheel 10 is driven to rotate, thereby driving the first rotating shaft 11 to rotate. The first rotating shaft 11 rotates to drive the second rotating shaft 12 to rotate through the belt. Similarly, the third rotating shaft 13 also rotates, thereby driving the gear 14 to rotate.

[0057] When the gear 14 rotates, the second telescopic column 801 is driven to slide in the second telescopic sleeve column 8 through the engagement with the rack groove 802, thereby driving the first telescopic column 701 to slide in the first telescopic sleeve column 7, so as to drive the mounting base 9 to move away from or close to the mounting plate 2, so that the faucet 17 moves away from or close to the mounting plate 2.

[0058] As a further scheme of the utility model, the rotating wheel mechanism comprises a water pipe wheel 16 rotatably installed on the fourth rotating shaft 15, and the fourth rotating shaft 15 and the first rotating shaft 11 are connected through a belt.

[0059] In this embodiment, when the telescopic mechanism drives the faucet 17 to rise, the water pipe connected between the faucet 17 and the water pipe wheel 16 is pulled tight and straight. In order to avoid damage to the connection or the water pipe, the rotating wheel mechanism is driven to move synchronously by the lifting mechanism to offset the pulling force.

[0060] The first rotating shaft 11 rotates to drive the fourth rotating shaft 15 to rotate through the belt, thereby driving the water pipe wheel 16 to rotate. After the water pipe wheel 16 rotates, the water pipe wound thereon is released, so that the length of the water pipe between the faucet 17 and the water pipe wheel 16 becomes longer, thereby offsetting the pulling force in the rising process.

[0061] The first telescopic column 701 and the second telescopic column 801 are driven to rotate by the arm lifting mechanism, the mounting base 9 is driven to rotate, the water outlet angle of the water faucet 17 is adjusted, the first telescopic column 701 and the second telescopic column 801 are driven to slide outwards in the first telescopic sleeve column 7 and the second telescopic sleeve column 8 by the lifting mechanism, the water outlet height of the water faucet 17 is adjusted, and the water pipe length is adjusted by the rotating wheel mechanism.

[0062] As a further scheme of the utility model, the mounting plate 2 is fixedly provided with a mounting frame, and the mounting frame is fixedly provided with a support plate in sliding fit with the inner threaded sleeve 5.

[0063] In the embodiment, the inner threaded sleeve 5 is given a support force by the support plate to support the main rotating shaft 4, so that the main rotating shaft 4, the screw rod column 401 and the worm 402 are prevented from deforming during operation of the device, thereby improving the service life and stability of the device.

[0064] As a further scheme of the utility model, the water faucet 17 is provided with a fan, and the fan can blow the liquid water into mist water.

[0065] In the embodiment, the liquid water is blown into mist water by the fan, and the mist water has a better dust-settling and temperature-lowering effect, so that the dust-settling and temperature-lowering effects of the device are improved.

[0066] The above embodiments are exemplary but not restrictive, and the technical scheme of the utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the utility model, and all the technical schemes are included in the utility model.
