It should be noted that the embodiments and features of the embodiments of the present invention may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0027] Example 1

[0028] like Figure 1 As shown, a joint provided in this embodiment includes a connecting air cylinder 2, an air flow main cylinder 3, a first universal tube 5, and a first air nozzle 6.

[0029] The connecting air duct 2 is a flexible tube made of polyethylene. One end of the connecting air duct 2 is provided with an interface 1 for connecting with the main air duct 10 (such as Figure 2 The other end of the connecting air cylinder 2 is connected to the air flow main cylinder 3, the first universal tube 5 and the first air nozzle 6 in sequence.

[0030] The wind main tube 3 is made of inorganic glass fiber reinforced plastic. A support ring 4 is provided on its upper side wall. During installation, nails can be driven into the rock wall, and the support ring 4 is hung on the nails.

[0031] The first universal tube 5 is a corrugated tube made of PVC material, which can be bent to adjust the position and direction of the first air nozzle 6, so that the airflow can reach the actual air-needing point in the working surface more directly, thereby improving the airflow utilization rate.

[0032] The first air nozzle 6 is a conical tube, with the end connected to the first universal tube 5 being the large-diameter end. Two, three, or more air dampers can be arranged circumferentially within the first air nozzle 6, with the center of the air damper being a rotating shaft. By rotating the rotating shaft, the air damper opening can be adjusted to adjust the air supply volume.

[0033] Example 2

[0034] like Figure 1 、 Figure 2 As shown, the first embodiment is repeated, except that, in this embodiment, the joint further includes a diverter plate 7, a second universal tube 8 and a second air nozzle 9.

[0035] An opening 31 is provided on the side wall of the main air flow cylinder 3. The diverter plate 7 includes a vertical plate 71 and a horizontal plate 72. The vertical plate 71 is arranged vertically and adjacent to the opening 31. The lower end of the vertical plate 71 is connected to the main air flow cylinder 3. The upper end of the vertical plate 71 is connected to the horizontal plate 72 arranged horizontally. The horizontal plate 72 is located above the opening 31, and a diverter port 32 is formed between the horizontal plate 72 and the inner wall of the main air flow cylinder 3. The two ends of the vertical plate 71 and the horizontal plate 72 are connected to the inner wall of the main air flow cylinder 3 (as shown in FIG. Figure 2 shown).

[0036] One end of the second universal tube 8 is connected to the opening 31, and the other end of the second universal tube 8 is connected to the second air nozzle 9. The structure of the second universal tube 8 is the same as that of the first universal tube 5, both utilizing a PVC bellows structure to achieve universal adjustment. The structure of the second air nozzle 9 is the same as that of the first air nozzle 6. In this embodiment, a support ring 4 is provided at each end of the outer wall of the main airflow tube 3 forming the opening 31.

[0037] Example 3

[0038] like Figure 3 As shown, this embodiment provides a cooling air duct device, comprising a main air duct 10 and the connector of Embodiment 1 or Embodiment 2. One end of the main air duct 10 is an air outlet 101, and the interface 1 of the connector interfaces with the air outlet 101. The other end of the main air duct 10 is connected to a fan. Alternatively, an exhaust fan may be connected to the other end of the main air duct 10 to extract exhaust gas from underground equipment.

[0039] The arrangement method of the cooling air duct device comprises the following steps:

[0040] S1, install the production requirements and the spacing of the support ring 4, and set the corresponding nails on the wellbore support;

[0041] S2, connect the main air duct 10 to the interface 1;

[0042] S3, hang the joint on the nail through the bracket ring 4;

[0043] S4, bending the first universal tube 5 and / or the second universal tube 8 according to the air-needed point, so that the first air nozzle 6 and / or the second air nozzle 9 are directed toward the operator and the equipment to perform cooling.

[0044] The currently commonly used underground main air duct is close to the rock wall, and the low-temperature clean fresh air flow cannot be effectively utilized. The utility model adjusts the air flow direction through the first universal tube and the second universal tube to make the air flow more directly reach the actual air-needing points in the working face, and the air flow utilization rate is high.

[0045] The high temperature and high humidity underground environment will affect the work efficiency of the operators. The traditional main air duct cannot provide a comfortable working environment for the operators on the working face due to the lack of concentrated cooling source, scattered airflow, and untimely heat dissipation of the operating equipment. The utility model can quickly improve the physical comfort of the operators by adjusting the angle and wind speed of the air duct.

[0046] In addition, the utility model can be used as both an air inlet duct and an air return duct. The combination of extraction and pressure on the working face can cover the air inlet and return needs of four different areas, and can fully meet the needs of air inlet and return on the working face, air use for personnel and heat dissipation of equipment.

[0047] The connector of the utility model is used in the same way as an ordinary main air duct and can be directly connected to an existing main air duct underground. It is lightweight and has a simple hanging method, and can effectively fit the actual air duct operation process on site.

[0048] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
