Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, in particular to a dust suppression device for water conservancy project construction. Background Art

[0002] During the construction of water conservancy projects, a large amount of dust will always be generated. Working in a dusty environment will greatly damage the health of workers, so dust reduction treatment is needed.

[0003] In the prior art, the liquid atomized by the spray head is sprayed out through the rapid airflow generated by the fan blades, thereby capturing the dust in the air and completing the dust reduction operation in the construction area. The height and the inclination angle of the first cylinder and the second cylinder can be adjusted through the cooperation of the hydraulic rod and the electric push rod. The spray area of ​​the device can be changed in conjunction with the rotating assembly to improve the spray efficiency of the device. In addition, the gathering and dispersion states of the multiple spray heads can be adjusted through the cooperation of the electric push rod and multiple adjustment rods. When the electric push rod is extended, on the one hand, it drives the first cylinder and the second cylinder to tilt upward, and at the same time adjusts the spray head to a gathering state, thereby realizing long-distance dust reduction of the dust reduction device. When the electric push rod is retracted, on the one hand, it drives the first cylinder and the second cylinder to tilt downward, and at the same time adjusts the spray head to a diffusion state, thereby realizing close-range and large-area dust reduction of the dust reduction device, reducing the density of local water mist, and preventing mud from appearing on the ground.

[0004] However, the existing technology is not convenient for automatically adjusting the convergence state of multiple spray heads according to the change of external wind direction. When the fan blades are in a headwind state, the fast airflow blown out by the fan becomes smaller due to the headwind, thereby shortening the distance of the spray dust reduction.

At this time, spraying is carried out. Since the spray heads are more gathered together, the density of the water mist will increase. Due to the increase in the density of the water mist, it can resist air resistance and spread farther, thereby achieving dust reduction at a longer distance, thereby compensating for the problem that the spray distance of the device becomes shorter due to the smaller wind force of the rapid airflow generated by the fan blades in the case of headwind, and the gathering and dispersion state of the multiple spray heads can be adaptively adjusted according to the wind force of the rapid airflow blown out by the fan blades, which is more convenient to use.

[0045] A connecting member 12, which is disposed in the fixed tube 4 and is connected to the slider 6 and the movable plate 10 respectively, and is used to connect the slider 6 and the movable plate 10;

[0046] An elastic pulling component 13, wherein the elastic pulling component 13 is disposed in the connecting frame 3 and connected to the slider 6, and is used to provide elastic pulling force for the slider 6;

[0047] A windward component 14, which is connected to the movable plate 10 and is used to bear the airflow blown by the fan blades 22. The windward component 14 includes a connecting rod 1401 connected to the movable plate 10, and one end of the connecting rod 1401 passing through the fixed tube 4 is equipped with a windward movable frame 1402 that is in contact with the outer wall of the fixed tube 4;

[0048] A regulating component 15, which is disposed between the fixed cylinder 4 and the windward movable frame 1402 and is used to actively control the position of the windward movable frame 1402;

[0049] A cleaning component 24, which is disposed in the support frame 18 and is used to clean dust on the surface of the filter screen 20;

[0053] The water supply assembly 28 is disposed on the rotating assembly 26 and is used to supply water to the spray head 8 .

[0054] When in use, the base 1 can be fixed at a specific position or on a transport vehicle. No further details are given here. When spray dust reduction is required, the entire device is powered on first, and the second drive member 23 is started so that the rotating shaft 21 can drive the fan blades 22 to rotate, thereby generating an outward rapid airflow, and the water supply component 28 supplies water to the spray head 8 so that the spray head 8 can atomize and spray the liquid. The rapid airflow generated by the fan blades 22 can spray the atomized liquid, which can then combine with the dust in the air to complete the dust reduction operation in the construction area of ​​the water conservancy project. In addition, the fast airflow generated by the fan blades 22 will blow the atomized liquid while also blowing the windward movable frame 1402. The windward movable frame 1402 will be pushed by the fast airflow, and then the movable plate 10 will be pushed to slide in the inner cavity 9 through the connecting rod 1401 until the movable plate 10 moves to its extreme position. In this process, under the pulling action of the elastic pulling component 13 and in cooperation with the connecting piece 12, the slider 6 will slide along the slide groove 5 toward the inner wall of the cylinder 2, and will slide from the end close to the fixed cylinder 4 to the other end of the slide groove 5, thereby changing the position of the spray head 8 and moving the spray head 8 to its initial working position. At this time, the width of the device that can spray dust is the largest, and the fast airflow blown by the fan blades 22 can achieve spray dust at a corresponding distance. When a headwind occurs, the fast airflow blown by the fan blades 22 is affected by the headwind, resulting in a smaller wind force, thereby causing the windward movable frame 1402 to be affected. When the thrust becomes smaller, the windward movable frame 1402 will move to the side away from the fixed cylinder 4 under the action of the first elastic member 11, and the connecting rod 1401 will also drive the movable plate 10 to move, so that the movable plate 10 will slide a certain distance along the inner cavity 9 toward the side of the windward movable frame 1402, and then the slider 6 can be driven by the connecting member 12 to slide a certain distance along the slide groove 5 toward the side of the fixed cylinder 4, so that the multiple spray heads 8 are slightly gathered together. At this time, spraying is carried out. Since the spray heads 8 are more gathered together, the density of the water mist will increase. Due to the increase in the density of the water mist, it can resist the air resistance and spread farther, thereby achieving dust reduction at a longer distance, thereby compensating for the problem that the spray distance of the device becomes shorter due to the smaller wind force of the fast airflow generated by the fan blades 22 in the case of headwind, and the gathering and dispersion state of the multiple spray heads 8 can be adaptively adjusted according to the wind force of the fast airflow blown out by the fan blades 22, which is more convenient to use.

[0055] In one case of this embodiment, the connecting member 12 includes a first connecting rope 1201, the two ends of which are respectively connected to the movable plate 10 and the slider 6, the fixing cylinder 4 is provided with a connecting channel 1202 for the first connecting rope 1201 to move, and a guide wheel 1203 that contacts the first connecting rope 1201 is rotatably arranged in the connecting channel 1202. The elastic pulling assembly 13 includes a cavity 1302 opened in the connecting frame 3 and close to the slide 5, and a second elastic member 1303 is arranged in the cavity 1302. Preferably, the second elastic member 1303 is set as a spring, and the second elastic member 1303 is connected to the second connecting rope 1301, and the second connecting rope 1301 is connected to the slider 6.

[0056] Wherein, due to the functions of the connecting channel 1202 and the guide wheel 1203, the first connecting rope 1201 is L-shaped.

[0057] In the initial state, under the action of the first elastic member 11, an elastic force is applied to the movable plate 10 toward the side of the windward movable frame 1402, so that the movable plate 10 is pressed against the end of the inner cavity 9 close to the windward movable frame 1402, and under the elastic pulling force of the second elastic member 1303 on the second connecting rope 1301, and in cooperation with the first connecting rope 1201, the position of the slider 6 in the slide groove 5 can be limited, and when the windward movable frame 1402 is pushed by the fast airflow blown out by the fan blades 22, the windward movable frame 1402 will drive the connecting rod 1401 to push the movable plate 10 to slide toward the other end of the inner cavity 9, and under the elastic pulling force of the second elastic member 1303 on the second connecting rope 1301, the slider 6 slides along the slide groove 5 toward the side away from the fixed cylinder 4, thereby changing the position of the multiple spray heads 8, wherein the elastic thrust of the first elastic member 11 is greater than the elastic pulling force of the second elastic member 1303.

[0058] In one case of the present embodiment, the regulating component 15 includes a fixed plate 1501 installed on both sides of the fixed cylinder 4, and a first telescopic member 1502 is installed on the fixed plate 1501. Preferably, the first telescopic member 1502 is set as a hydraulic rod, and the first telescopic member 1502 is fixedly connected to the movable outer frame 1503. The two ends of the movable outer frame 1503 are installed with a first driving member 1504. Preferably, the first driving member 1504 is set as a servo motor, and the first driving member 1504 is connected with a clamping block 1505. Two limit blocks 1506 corresponding to the clamping block 1505 are installed on the side of the windward movable frame 1402 close to the fixed cylinder 4, and a clamping slot 1507 is opened in the limit block 1506, and the clamping slot 1507 is T-shaped.

[0059] In the present invention, in addition to adaptively adjusting the wind force of the airflow blown out by the fan blades 22, the convergence and divergence state of the multiple spray heads 8 can also be actively controlled by the regulating component 15. When it is necessary to actively control the convergence and divergence state of the multiple spray heads 8, the first telescopic member 1502 is activated by the external controller so that the first telescopic member 1502 can drive the movable outer frame 1503 to move toward the windward movable frame 1402 until the block 1505 can enter the slot 1507 of the limit block 1506, and then the first drive is activated. Part 1504, the first driving part 1504 drives the card block 1505 to rotate 90 degrees, so that the card block 1505 is completely stuck in the card slot 1507 of the limit block 1506, and then by adjusting the telescopic length of the first telescopic part 1502, the position of the windward movable frame 1402 can be actively changed, that is, the position of the movable plate 10 in the inner cavity 9 can be changed, so that the positions of the multiple spray heads 8 in the slide groove 5 can also be actively changed, so that the gathering and dispersion states of the multiple spray heads 8 can be actively controlled, and automatic and manual dual control can be realized.

[0060] In one case of this embodiment, a protective cover 16 is installed at one end of the connecting frame 3 close to the fixing tube 4 , and an entrance port 17 is opened at a side of the protective cover 16 away from the fixing tube 4 .

[0061] In the initial state, that is, the windward movable frame 1402 is not pushed by the fast airflow generated by the fan, the spray head 8 is located in the protective cover 16. When the windward movable frame 1402 is pushed by the fast airflow, the slider 6 will slide along the slide groove 5 to one side of the inner wall of the cylinder 2, and then can be moved out of the protective cover 16 from the entrance port 17. When the device is shut down, the windward movable frame 1402 will gradually reset, so that the slider 6 will slide along the slide groove 5 to the end close to the fixed cylinder 4 until the spray head 8 enters the protective cover 16 through the entrance port 17, so that when the device is shut down, the spray head 8 can be protected to prevent the spray head 8 from being exposed and damaged.

[0062] Example 2

[0063] See also Figure 1-Figure 14The other contents of this embodiment are the same as those of embodiment 1, except that: the cleaning component 24 includes a movable cavity 2401 opened in the support frame 18, a movable plate 2402 is slidably arranged in the movable cavity 2401, a plurality of movable rods 2403 passing through the support frame 18 are installed on the movable plate 2402, a knocking block 2404 is installed at one end of the movable rod 2403 away from the movable plate 2402, and the movable plate 2402 is connected to one end of the movable cavity 2401 close to the filter screen 20 through a third elastic member 2405. Preferably, the third elastic member 2405 is configured as a spring. The control component 25 includes a conductive block 2501 installed at one end of the inner cavity 9 away from the connecting frame 3, a conductive slider 2502 is installed on the side of the movable plate 10 close to the conductive block 2501, a permanent magnet 2503 is installed on the movable plate 2402, and an electromagnet 2504 is installed at one end of the movable cavity 2401 away from the filter 20, wherein the conductive block 2501, the conductive slider 2502, the electromagnet 2504 and the external power supply device are electrically connected.

[0064] When the device is powered on, under the action of the first elastic member 11, the movable plate 10 is pressed against one end of the inner cavity 9 close to the windward movable frame 1402. At this time, the conductive slider 2502 and the conductive block 2501 are in contact, so that the electromagnet 2504 is powered on to generate magnetism. Due to the elastic force of the third elastic member 2405, the permanent magnet 2503 on the movable plate 2402 fits with the electromagnet 2504. Therefore, when the electromagnet 2504 is powered on, the magnetism of the electromagnet 2504 and the permanent magnet 2503 near the end is the same. The magnetism generated by the electromagnet 2504 pushes the movable plate 2402 connected to the permanent magnet 2503 to move toward one end of the filter 20, so that the knocking block 2404 at the end of the movable rod 2403 knocks the tail of the filter 20. The upper mounting frame 19 causes the filter 20 on the rear mounting frame 19 to vibrate, thereby shaking off the dust and impurities on the filter 20, thereby avoiding the blockage of the filter 20 during the operation of the device and affecting the normal entry of air into the cylinder 2. In addition, after the device is used up and the power is cut off, the movable plate 10 will also be reset under the action of the first elastic member 11. At this time, the conductive slider 2502 and the conductive block 2501 will also contact again, and then the permanent magnet 2503 will be energized again, and the above operation will be repeated, so that the knocking block 2404 will knock the rear mounting frame 19 again, causing the filter 20 to vibrate, thereby shaking off the dust and impurities filtered on the filter 20 during the use of the device, avoiding the dust and impurities attached to the filter 20 due to failure to clean in time, which will make subsequent cleaning difficult.

[0065] In one case of this embodiment, the rotating assembly 26 includes a movable shaft 2601 rotatably set on the base 1, and a rotating frame 2602 in contact with the surface of the base 1 is installed on the movable shaft 2601.
