Description

Technical Field

[0001] This utility model relates to the field of mine surveying, and in particular to a mine safety surveying device. Background Technology

[0002] In mining operations, ventilation systems play a crucial role in ensuring the safety of underground workers and maintaining normal production order. In poorly ventilated areas, such as dead-end tunnels, blind tunnels, and areas near goaf, local ventilation fans can effectively deliver fresh air to these areas. As a key piece of equipment in the mine ventilation system, the operating status of local ventilation fans directly affects the air quality and ventilation effect in local underground areas.

[0003] Accurately measuring the wind speed of local ventilation fans is crucial for ensuring the stable operation of ventilation systems and for promptly identifying and eliminating safety hazards. Currently, wind speed measurements of local ventilation fans in mines primarily rely on existing anemometers, and a large number of non-standard ventilation fans used in mines have diameter variations exceeding ±15%.

[0004] Existing anemometers cannot be flexibly fixed inside local ventilation fans of different sizes, making it impossible to conduct effective measurements. They are generally suspended inside the fan using brackets, but this causes the anemometer to be unstable during measurement, affecting the accuracy and timeliness of the wind speed measurement data.

[0025] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0026] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0027] Reference Figures 1-5 A mine safety measuring device includes: an anemometer 200, which is installed at the air outlet of a ventilator; a support arm 300, one end of which is connected to the anemometer 200; and a positioning seat 400, which is installed at the other end of the support arm 300 and is configured to be closer to or further away from the support arm 300, wherein the positioning seat 400 is installed at the edge of the ventilator.

[0028] In this embodiment, the anemometer 200 is fixed to the air outlet of the ventilator by the support arm 300, and the positioning seat 400 is installed on the edge of the ventilator to provide stable support for the entire device. The adjustable structure of the support arm 300 and the positioning seat 400 allows the measuring device to adapt to ventilators of different sizes.

[0029] The support arm 300 includes: an adjustment groove 301, which is formed at one end of the support arm 300; an adjustment arm 302, which is installed in the adjustment groove 301, and a positioning seat 400 is installed at one end of the adjustment arm 302; and a first lead screw 303, which is connected at one end to the adjustment arm 302 and at the other end passes through the inner wall of the adjustment groove 301.

[0030] By rotating the first lead screw 303, the adjusting arm 302 can be driven to move within the adjusting groove 301, thereby achieving precise adjustment of the length of the support arm 300. The first lead screw 303 and the adjusting arm 302 are connected by a thread, which has a self-locking function and can ensure the stability of the length of the support arm 300 after adjustment.

[0031] The wind speed measuring instrument 200 includes: a mounting frame 100, in which the wind speed measuring instrument 200 is mounted; an adjusting plate 102, sleeved on the mounting frame 100, with one end of the support arm 300 mounted on the adjusting plate 102; a first gear 101, mounted on the mounting frame 100, with a groove on the inner ring of the adjusting plate 102, and a second gear 305 disposed in the groove, the second gear 305 meshing with the first gear 101; a first bevel gear 304, disposed in the groove, with one end of the first lead screw 303 connected to the first bevel gear 304; and a second bevel gear 306, mounted on the second gear 305, with the first bevel gear 304 meshing with the first bevel gear 304.

[0032] The aforementioned mounting bracket 100 provides a stable installation environment for the anemometer 200. When the adjusting plate 102 is rotated, the adjusting plate 102 rotates on the mounting bracket 100, and the adjusting plate 102 also drives the second gear 305 to mesh and rotate on the first gear 101. The second gear 305 drives the second bevel gear 306 to rotate, and the second bevel gear 306 drives the first bevel gear 304 and the first lead screw 303 to rotate. The first lead screw 303 can drive the adjusting arm 302 to move, and the adjusting arm 302 drives the positioning seat 400 to move, so as to adjust the position of the positioning seat 400.

[0033] The positioning seat 400 includes: a positioning groove 401, formed on one side of the positioning seat 400; a first clamping head 402, installed on the bottom wall of the positioning groove 401; a second clamping head 404, disposed on the top wall of the positioning groove 401, the second clamping head 404 being configured to move closer to or further away from the first clamping head 402; a moving groove 403, formed on the top wall of the positioning groove 401, the second clamping head 404 being connected to the moving groove 403; a second lead screw 405, one end of which is connected to the second clamping head 404, and the other end of which passes through the inner wall of the moving groove 403; and a knob 406, installed on one end of the second lead screw 405.

[0034] The aforementioned positioning groove 401 enables the positioning seat 400 to accurately align with the edge of the ventilator, improving the accuracy of device installation. By adjusting the position of the second clamping head 404, the edge of the ventilator can be clamped or released, thereby firmly installing the positioning seat 400 on the ventilator. By rotating the knob 406, the knob 406 drives the second lead screw 405 to rotate, which can drive the second clamping head 404 to move within the moving groove 403, thereby adjusting the clamping force on the edge of the ventilator. The range of motion of the second clamping head 404 can adapt to ventilator housings of different thicknesses.

[0035] The number of support arms 300 is at least two, providing stable support for the anemometer 200. Multiple support arms 300, in conjunction with an adjustable positioning seat 400, can securely fix the device to the ventilator.

[0036] During use, when the adjusting plate 102 is rotated, it rotates on the mounting bracket 100. The adjusting plate 102 also drives the second gear 305 to mesh and rotate with the first gear 101. The second gear 305 drives the second bevel gear 306 to rotate, which in turn drives the first bevel gear 304 and the first lead screw 303 to rotate. The first lead screw 303 can move the adjusting arm 302, which in turn moves the positioning seat 400, adjusting it to a position close to the size of the ventilator. The positioning seat 400 is then placed at the edge of the ventilator, so that the edge of the ventilator is embedded in the positioning groove 401 on one side of the positioning seat 400. The design of the positioning groove 401 allows the positioning seat 400 to accurately align with the edge of the ventilator, improving installation accuracy. Operating the knob 406 rotates the second lead screw 405. One end of the second lead screw 405 is connected to the second clamping head 404, and the other end passes through the inner wall of the moving groove 403. The second clamping head 404 is connected inside the moving groove 403. As the second lead screw 405 rotates, it drives the second clamping head 404 to move closer to the first clamping head 402 inside the moving groove 403, thereby clamping the edge of the ventilator and firmly installing the positioning seat 400 on the ventilator. At the same time, the clamping force can be adjusted by rotating the knob 406. After completing the above installation and adjustment work, the anemometer 200 starts to work and measures the wind speed at the ventilator outlet in real time. Due to the adjustable structure of the support arm 300 and the positioning seat 400, as well as the flexible adjustment of the angle of the anemometer 200, the measuring device can adapt to ventilators of different sizes and keep the anemometer 200 in the optimal measuring position and angle, thereby obtaining accurate and reliable wind speed data.

[0037] In summary, compared with existing technologies, it has the following beneficial effects:

[0038] Through the adjustable structure of the support arm 300, rotating the first lead screw 303 can drive the adjusting arm 302 to move within the adjusting groove 301, thereby achieving precise adjustment of the length of the support arm 300. The second clamping head 404 on the positioning seat 400 can drive the second lead screw 405 to rotate by rotating the knob 406, and move within the moving groove 403, thereby achieving adjustment of the clamping force on the edge of the ventilator, so that the measuring device can flexibly adapt to local ventilators of different diameters.

[0039] By rotating the knob 406, the second clamping head 404 can be driven to move within the moving slot 403, thereby adjusting the clamping force on the edge of the ventilator. The range of movement of the second clamping head 404 can adapt to ventilator housings of different thicknesses.
