Description

Technical Field

[0001] The utility model relates to the field of mining sensor installation equipment, in particular to an adjustable mine wind speed sensor hanger. Background Art

[0002] The underground wind speed sensor is a device used to measure the size of the wind force underground. It can monitor the wind speed in the ventilation system and transmit the data to the monitoring equipment for analysis and processing. By monitoring the wind speed, miners can be helped to detect changes in harmful substances such as coal dust and methane in a timely manner, and take early warning and preventive measures in time to avoid possible disasters. At the same time, it ensures that miners have sufficient oxygen supply when working and guarantees the quality of the air underground. At present, the wind speed sensor is usually fixed on the top surface of the mine tunnel by means of a bracket and other devices, but the position of the bracket is often easily deviated during construction, resulting in the wind speed sensor fixed on the frame not being able to face the wind flow direction well, making it difficult for the air inlet of the wind speed sensor to be aligned with the wind flow direction, resulting in a large deviation in the test results.

[0017] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0018] For the convenience of description, if the words "up", "down", "left" and "right" appear in the utility model, they only indicate that they are consistent with the up, down, left and right directions of the drawings themselves, and do not limit the structure. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the equipment or components referred to need to have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the utility model. Now, the technical solution of the utility model is further explained in conjunction with the drawings of the specification.

[0019] refer to Figure 1 and Figure 2 , an adjustable underground wind speed sensor bracket is exemplified, comprising: a fixed plate 1, a connecting rod 2, a rotating sleeve 3, a first limit block 4, a fastening bolt 5, a cross bar 6, a support arm 7, a mounting plate 8 and a telescopic device. Specifically: the fixed plate 1 is arranged horizontally, the connecting rod 2 is arranged vertically, and its upper end is fixed on the lower surface of the fixed plate 1. The rotating sleeve 3 is sleeved on the lower end of the connecting rod 2, and the inner cavity diameter of the rotating sleeve 3 is larger than the diameter of the connecting rod 2, so that the rotating sleeve 3 can rotate relative to the connecting rod 2.

[0020] The first stopper 4 is fixed on the side wall of the connecting rod 2 and is located above the rotating sleeve 3. The fastening bolt 5 is threadedly connected to the screw hole on the lower end surface of the connecting rod 2, and the rotating sleeve 3 is fastened between the first stopper 4 and the fastening bolt 5. At this time, the upper and lower ends of the rotating sleeve 3 are respectively in contact with the first stopper 4 and the fastening bolt 5. When the fastening bolt 5 is loosened, the rotating sleeve 3 can rotate relative to the connecting rod 2.

[0021] The cross bar 6 is arranged horizontally, and its left end is fixed on the outer wall of the rotating sleeve 3. The support arm 7 is arranged obliquely upward, and its lower end is rotatably connected to the right end of the cross bar 6 through a pin shaft, and the back of the mounting plate 8 is rotatably connected to the upper end of the support arm 7. The telescopic device includes a first screw rod 9, a second screw rod 10 and an adjustment ring 11. Among them: the lower end of the first screw rod 9 is rotatably connected to the cross bar 6, the upper end of the second screw rod 10 is rotatably connected to the back of the mounting plate 8, and the first screw rod 9 and the second screw rod 10 are symmetrically distributed on both sides of the adjustment ring 11. The upper end of the first screw rod 9 and the lower end of the second screw rod 10 are both threadedly connected to the adjustment ring 11, and the thread rotation direction of the first screw rod 9 and the adjustment ring 11 is opposite to the thread rotation direction of the second screw rod 10 and the adjustment ring 11. When the adjustment ring 11 is rotated, the first screw rod 9 and the second screw rod 10 can be moved closer to or away from each other, so that the mounting plate 8 rotates.

[0022] When in use, the fixing plate 1 is fixed on the top wall of the tunnel of the mine. Due to the inevitable existence of construction errors, the fixing plate 1 is easily deflected. In addition, in many cases, the top wall of the tunnel cannot be guaranteed to be in a flat state, which will also cause the fixing plate 1 and the connecting rod 2 to be in an inclined state. At this time, if the wind speed sensor fixed on the connecting rod 2 cannot be adjusted, once the air inlet of the wind speed sensor cannot be well consistent with the wind flow direction, it will affect the accuracy of the wind speed measurement result. In this embodiment, the mounting plate 8 can be rotated in the horizontal direction by rotating the rotating sleeve 3 connected to the connecting rod 2. At the same time, the mounting plate 8 can be rotated at a certain angle in the vertical direction through the cooperation between the cross bar 6, the support arm 7 and the telescopic device. Through the adjustment in the above two directions, the air inlet of the wind speed sensor installed on the mounting plate 8 can be kept consistent with the wind flow direction as much as possible, reducing the measurement error.

[0023] In another embodiment, reference Figure 1 In the above embodiment, a rubber gasket 12 is provided between the fastening bolt 5 of the adjustable underground wind speed sensor bracket and the bottom surface of the rotating sleeve 3, and the rubber gasket 12 is sleeved on the fastening bolt 5. The friction between the fastening bolt 5 and the rotating sleeve 3 can be increased by the rubber gasket 12, so that the rotating sleeve 3 can be better fixed on the connecting rod 2 to prevent rotation.

[0024] In another embodiment, reference Figure 1 The adjustable underground mine wind speed sensor bracket of the above embodiment further includes an inclined support rod 13, the lower end of the support rod 13 is fixedly connected to the rotating sleeve 3, and the upper end of the support rod 13 is fixedly connected to the cross bar 6. The support rod 13 can support the cross bar 6 and increase the supporting force of the cross bar 6.

[0025] In another embodiment, reference Figure 1 and Figure 2 The adjustable underground mine wind speed sensor rack of the above embodiment further includes a water retaining shed 14, which is fixed on the connecting rod 2 and located above the mounting plate 8. The water retaining shed 14 helps to prevent the wind speed sensor on the mounting plate 8 from being damaged when water leaks from the top wall of the tunnel.

[0026] In another embodiment, reference Figure 1 and Figure 2 The top surface of the water retaining shed 14 of the adjustable underground wind speed sensor bracket of the above embodiment is provided with a fixing pipe 15, the connecting rod 2 passes through the fixing pipe 15 and the water retaining shed 14, and the side wall of the fixing pipe 15 is provided with a screw hole, in which a bolt is connected and the fixing pipe 15 and the connecting rod 2 are fastened together, so that the water retaining shed 14 can be detachably fixed on the connecting rod 2. A second limit block 16 can also be provided on the side wall of the connecting rod 2, and the water retaining shed 14 is supported on the second limit block 16.

[0027] Finally, it should be noted that any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model. Although the above describes the specific implementation of the utility model in conjunction with the drawings, it is not a limitation on the protection scope of the utility model. Those skilled in the art should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by those skilled in the art without creative labor are still within the protection scope of the utility model.
