[0045] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] like Figures 1 to 5 As shown, the first embodiment of the present invention provides a dust suppression and dust reduction device, which includes a support base 10, a movable structure 20, a spraying member 30, and a lifting drive structure 40. The support base 10 has a support space 11. One end of the movable structure 20 is movably disposed in the support space 11, and the other end of the movable structure 20 extends out of the support space 11. The spraying member 30 is connected to the other end of the movable structure 20. The lifting drive structure 40 includes a water pipe structure 41 and a control valve structure 42 disposed on the water pipe structure 41. The control valve structure 42 is openable and closable. The water pipe structure 41 has a water inlet state for allowing water to enter the support space 11, a disconnection state for disconnecting from the support space 11, and a drainage state for allowing water in the support space 11 to flow out through the water pipe structure 41. Among them, when the water pipe structure 41 is in the water inlet state, the water in the water pipe structure 41 flows into the support space 11 and pushes the movable structure 20 to move upward; when the water pipe structure 41 is in the drainage state, the water in the support space 11 flows out through the water pipe structure 41 and allows the movable structure 20 to have movable space for downward movement.

[0047] By using the dust suppression and dust reduction device provided in this embodiment, the upper and lower positions of the movable structure 20, that is, the height, can be adjusted by adjusting the water inlet and drainage states of the water pipe structure 41. This allows the height of the spray element 30 to be adjusted, making it easier to adaptively adjust the height of the spray element 30 according to the actual height of the dust suppression and dust reduction or the height of the underground tunnel. The above adjustment method is simple, requiring only adaptive adjustment of the control valve structure 42 to switch the water pipe structure 41 to the water inlet state or the drainage state, thereby improving the convenience of height adjustment. Therefore, the technical solution provided by the utility model can solve the technical problem of the inconvenience of adjusting the height of the dust suppression and dust reduction device in the prior art.

[0048] In this embodiment, the water pipe structure 41 includes an inlet branch pipe 411 and an outlet branch pipe 412, both of which are connected to the support base 10; the control valve structure 42 includes an inlet control valve 421 and an outlet control valve 422, the inlet control valve 421 being arranged on the inlet branch pipe 411, and the outlet control valve 422 being arranged on the outlet branch pipe 412, both of which are openable and closable. When the water pipe structure 41 is in the water inlet state, the inlet control valve 421 is open and the outlet control valve 422 is closed; when the water pipe structure 41 is in the water discharge state, the inlet control valve 421 is closed and the outlet control valve 422 is open. The dust suppression and reduction device provided in this embodiment does not require the use of a wrench, and can easily control the water inlet control valve 421 and the water outlet control valve 422 to achieve switching of the water inlet state and the water outlet state of the water pipe structure 41. It is simple to operate, convenient to control, and has strong operational flexibility.

[0049] Specifically, the movable structure 20 includes a partition 21 and a movable rod 22 that are connected to each other. The partition 21 is adapted to the inner peripheral wall of the support space 11. The partition 21 is used to divide the support space 11 into a water inlet chamber 111 and a movable chamber 112 that are isolated from each other. The water inlet chamber 111 is located below the movable chamber 112. The water pipe structure 41 is used to connect or disconnect with the water inlet chamber 111. The periphery of the movable rod 22 is spaced apart from the inner peripheral wall of the support space 11. The movable rod 22 is movably arranged in the movable chamber 112. One end of the movable rod 22 away from the partition 21 forms the other end of the movable structure 20. With such a structural arrangement, it is easy to form the water inlet chamber 111 and the movable chamber 112 that are isolated from each other, so as to better drive the partition 21 and the movable rod 22 to move through the water inlet chamber 111. In addition, the above arrangement can also enable the movable rod 22 to be raised and lowered smoothly, thereby avoiding shaking during the spraying process and improving the dust reduction effect.

[0050] Specifically, a connecting sleeve 221 is provided on the movable rod 22 , and the spraying element is installed in the connecting sleeve 221 .

[0051] In this embodiment, the movable structure 20 further includes a seal 50, which is mounted on the partition 21 and located between the partition 21 and the inner peripheral wall of the support space 11. This facilitates better separation of the water inlet chamber 111 and the movable chamber 112, so that the water in the water inlet chamber 111 can stably drive the partition 21 to move.

[0052] Specifically, the sealing member 50 is a sealing ring with a simple structure and good sealing stability.

[0053] Specifically, a mounting groove adapted to the sealing member 50 is provided at the periphery of the partition 21, and the sealing member 50 is mounted in the mounting groove, thereby facilitating the improvement of the mounting stability of the sealing member 50.

[0054] In this embodiment, the support base 10 is provided with a guide hole 113 that communicates with the support space 11. The guide hole 113 is adapted to the shape of the movable rod 22, so that the movable rod 22 can be movably inserted into the guide hole 113. This facilitates smooth and stable guidance of the movement of the movable rod 22, ensures the linear movement of the movable rod 22, avoids deviation and jamming of the movable rod 22, improves the accuracy of the spraying, and effectively suppresses dust.

[0055] Specifically, the guide through hole 113 is a square hole. In this way, the movable rod 22 can be prevented from rotating when it is lifted or lowered in the guide through hole 113, so as to ensure smoothness in guiding the up and down movement of the movable rod 22.

[0056] Specifically, the inner peripheral wall of the support space 11 is an arc-shaped wall, so that the partition 21 can be easily matched with the inner peripheral wall and avoid the situation where the partition 21 has a large friction when moving up and down relative to the inner peripheral wall.

[0057] In this embodiment, the dust suppression and reduction device further includes a water supply pipe 60 and a connecting pipe 70. The water supply pipe 60 is connected to at least a portion of the water pipe structure 41. One end of the connecting pipe 70 is connected to the water supply pipe 60, and the other end of the connecting pipe 70 is connected to the spray element 30. The connecting pipe 70 is provided with an on / off control valve 80, which can be opened and closed. In this way, a single water supply pipe 60 can provide water to both the water pipe structure 41 and the spray element 30, facilitating water supply operations and simplifying the piping structure.

[0058] In this embodiment, the dust suppression and dust reduction device also includes a support plate 90 and at least two support columns 100, and the support base 10 and the water supply pipe 60 are both mounted on the support plate 90. At least two support columns 100 are connected to the support plate 90, and at least two support columns 100 are spaced apart below the support plate 90, and the end of each support column 100 away from the support plate 90 is a conical structure. With such a structural arrangement, the design of the conical support column 100 enables the device to be stably placed on uneven ground, thereby expanding its scope of application and being suitable for environments with complex terrain, such as underground construction in coal mines. In underground construction operations in coal mines, the ground conditions are complex and changeable. The conical support column 100 can ensure that the dust suppression and dust reduction device is stably placed on various terrains, thereby improving the adaptability and stability of the device. In addition, it can effectively reduce dust pollution during the construction process, while also providing a healthier working environment for construction workers.

[0059] Specifically, the support column 100 can be a steel chisel.

[0060] Specifically, the support plate 90 includes a first plate body 91 and a second plate body 92 connected to each other, the first plate body 91 and the second plate body 92 being connected at a preset angle, the second plate body 92 being connected to the middle portion of the first plate body 91, three support columns 100 being provided, two support columns 100 being located at either end of the first plate body 91, and another support column 100 being located at an end of the second plate body 92 away from the first plate body 91, and at least two support seats 10 being provided, spaced apart along the extension direction of the first plate body 91. Specifically, this design not only improves the structural stability of the device, but also enhances its flexibility and adaptability, making it suitable for scenarios requiring spraying at different locations and improving the dust suppression and reduction effect.

[0061] Specifically, the support plate 90 is a T-shaped plate structure.

[0062] Specifically, the connecting pipe 70 is a hose. Through the hose connection, the spraying member 30 can be flexibly adjusted in position according to actual needs, further improving the practicality and dust reduction effect of the device.

[0063] Specifically, a mounting hole is provided at the other end of the movable structure 20 , and the spraying member 30 is installed in the mounting hole to improve the installation stability of the spraying member 30 so that the height of the spraying member 30 can be flexibly adjusted.

[0064] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the dust suppression and dust reduction device of the present application realizes automatic adjustment of the spray height through hydraulic drive, which not only reduces the operating cost and improves the stability and safety of the system, but also enhances the adaptability and flexibility of the device through its structural design and component optimization, and is suitable for various dust-raising environments and scenarios, such as underground coal mine operations. The device can not only effectively improve the dust reduction efficiency and coverage, but also flexibly adjust the spray height and position according to actual needs to meet the dust reduction needs in different environments, showing a wide range of market application prospects and environmental protection value.
