Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mine environmental monitoring technology, and in particular relates to a mine vibration sensor angle adjustment device. Background Technology
[0002] In fields such as mining, geological exploration, and earthquake monitoring, the installation angle of vibration sensors (such as geophones) is crucial to signal reception accuracy. Traditional installation methods make it difficult to ensure the sensor is perfectly perpendicular, and the angle is difficult to adjust after installation, leading to increased signal reception errors and affecting data quality. Experiments show that when the geophone tilt angle is within 15°, the signal error can be controlled below 4%, and within 5°, the error is less than 0.4%, resulting in higher data reliability. Therefore, developing a device that can quickly and accurately adjust the sensor angle is of great significance for improving the accuracy and reliability of monitoring data.
[0003] Most current angle adjustment devices suffer from problems such as complex structure, inconvenient operation, and low adjustment accuracy, making them unsuitable for the rapid installation and high-precision adjustment requirements in complex environments such as mines. Furthermore, existing devices lack stability and durability, making them susceptible to external environmental influences, which can lead to decreased adjustment accuracy or device damage. Therefore, designing a simple, easy-to-operate, highly accurate, and stable angle adjustment device for mine vibration sensors is a pressing technical problem that needs to be solved.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with specific embodiments and the appendix, provides further details. Figure 1-8 The present invention will be described in further detail below. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the present invention.
[0026] A mine vibration sensor angle adjustment device achieves rapid coarse adjustment and high-precision fine adjustment of the sensor angle through the coordinated action of coarse adjustment component 3, fine adjustment component 2 and horizontal adjustment component 1.
[0027] The coarse adjustment component 3 includes a coarse adjustment base 38 and a coarse adjustment cover plate 33, which rotates under the action of the coarse adjustment rotating component. The coarse adjustment rotating component consists of a coarse adjustment shaft 37, a first coarse adjustment bevel gear 35, and a second coarse adjustment bevel gear 31. The second coarse adjustment bevel gear 31 is fixedly mounted on the coarse adjustment cover plate 33. The coarse adjustment shaft 37 is radially mounted on the coarse adjustment base 38 via bearings, and has rotating handles 36 at both ends. Rotating the handles 36 operates the coarse adjustment shaft 37, causing the first coarse adjustment bevel gear 35 to drive the second coarse adjustment bevel gear 31 to rotate, thereby causing the coarse adjustment cover plate 33 to rotate.
[0028] The coarse adjustment cover plate 33 is provided with an annular insertion groove, and the top of the coarse adjustment base 38 is embedded in the insertion groove. The top of the coarse adjustment base is provided with a ball bearing, and the bottom of the coarse adjustment cover plate 33 is provided with a ball bearing to improve the lubrication of rotation and reduce friction. The coarse adjustment cover plate 33 is provided with a plurality of fixing slots evenly distributed radially, and the side wall of the coarse adjustment base 38 is provided with a plurality of fixing holes corresponding to the fixing slots evenly distributed. Magnetic pins are inserted into at least two corresponding fixing slots and fixing holes. The magnetic pins are first inserted into the outer fixing slots and fixing holes and the inner fixing slots. The coarse adjustment base 38 and the coarse adjustment cover plate 33 are made of magnetically attracted material. Stable fixation after coarse adjustment is achieved by inserting and fixing with magnetic pins.
[0029] The coarse adjustment component 3 enables the sensor to quickly adjust its angle within a wide range, facilitating rapid positioning of the approximate monitoring direction under complex terrain conditions and greatly improving installation efficiency. Meanwhile, the magnetic pin 32 ensures stability after coarse adjustment, preventing angle shift due to external forces.
[0030] The fine-tuning component 2 is connected to the coarse-tuning cover plate 33 and includes a fine-tuning cover plate 27, a fine-tuning base 207, a fine-tuning shaft 22, a first fine-tuning bevel gear 206, a second fine-tuning bevel gear 204, an axial shaft 205, a constraint buckle 29, a first fine-tuning gear 201, a secondary gear 202, and a driven gear 203.
[0031] The fine-tuning component 2 includes a fine-tuning cover plate 27 and a fine-tuning base 207 rotatably embedded in the fine-tuning cover plate 27. The fine-tuning base 207 is rotatably equipped with a fine-tuning shaft 22 via a bearing 208. Handles are provided at both ends of the fine-tuning shaft 22 extending out of the fine-tuning base 207. A first fine-tuning bevel gear 206 is fixedly mounted on the fine-tuning shaft 22. An axial shaft 205 is rotatably mounted at the center of the fine-tuning base 207. The axial shaft 205 rotatably passes through the fine-tuning cover plate 27 and connects to a constraint buckle 29. A second fine-tuning bevel gear 204, which meshes with the first fine-tuning bevel gear 206, is fixedly mounted on the rotating shaft 205. A constraint plate 28 is radially mounted on the fine-tuning cover plate 27. A first fine-tuning gear 201 is mounted on the axial rotating shaft 205. The first fine-tuning gear 201 is located between the fine-tuning cover plate 27 and the constraint plate 28. The first fine-tuning gear 201 is driven by a driven gear 203 on the fine-tuning cover plate 27 through a secondary gear 202. The fine-tuning cover plate 27 and the fine-tuning base 207 are connected by a fine-tuning fixing member.
[0032] The fine-tuning shaft 22 is mounted on the fine-tuning base 207 via bearings, and has handles at both ends for fine-tuning operation. The first fine-tuning bevel gear 206 on the fine-tuning shaft 22 meshes with the second fine-tuning bevel gear 204 on the axial shaft 205, driving the axial shaft 205 to rotate. The axial shaft 205 passes through the fine-tuning cover plate 27 and is connected to the constraint buckle 29. The constraint plate 28 is fixed to the fine-tuning cover plate 27. The first fine-tuning gear 201 is mounted on the axial shaft 205 and is driven by the intermediate gear 202 and the driven gear 203 to achieve the fine-tuning function.
[0033] The fine-tuning fastener includes at least two fixing hooks 24 evenly arranged on the fine-tuning cover plate 27. The fine-tuning base 207 is welded to the outside with a hook frame 23. The hook frame 23 is evenly provided with a plurality of lifting holes 231. The lifting holes 231 are provided in at least two rows and are staggered. The fixing hooks 24 include rubber belts.
[0034] The fine-tuning fixture includes a fixing hook fixed to the fine-tuning cover plate and a hook bracket welded to the outside of the fine-tuning base. The hook bracket has staggered lifting holes, and the fixing hook is connected by a rubber belt made of a high-elasticity material. This fine-tuning design further improves the accuracy of angle adjustment. Through fine adjustment of the fine-tuning components, the sensor angle can be accurate to a very small range, ensuring the sensitivity and accuracy of signal reception, thereby improving the quality of monitoring data. At the same time, the flexible connection of the rubber belt ensures the stability of the fine-tuning components while allowing a certain degree of fine-tuning movement, avoiding damage to the device due to excessive rigidity.
[0035] The leveling component 1 is mounted on the upper end of the fine-tuning component 2 and connected to the fine-tuning component 2 via a mounting threaded seat 26. The leveling component 1 includes a leveling housing 14, a first leveling shaft 18, a second leveling shaft 11, a third leveling shaft 17, a worm gear 16, a worm wheel 15, and a leveling bevel gear. The first leveling shaft 14 is radially inserted into the leveling housing 14, and bubble level gauges 12 are provided at both ends. Each bubble level gauge 12 includes a fixing plate 13 fixedly mounted at the end of the first leveling shaft 14, and a short anchor rod 12 is mounted on the fixing plate 13 for connecting an external detector. A level gauge 19 is provided at the connection between the fixing plate 13 and the first leveling shaft 18 for monitoring the level status.
[0036] The second horizontal rotating shaft 11 rotates on the horizontal adjustment housing 14 and is equipped with a worm gear 16, which meshes with a worm wheel 15. The worm wheel 15 is fixedly mounted on the third horizontal rotating shaft 17. The third horizontal rotating shaft 17 is radially rotatably mounted on the horizontal adjustment housing 14 via bearings. A horizontal bevel gear is fixed on the shaft and meshes with the bevel gear rod on the first horizontal rotating shaft. Through the rotation function of the horizontal adjustment component, the bubble level can rotate around the central axis of the first horizontal rotating shaft to achieve horizontal calibration of the sensor. The fixing plate of the bubble level adopts a leaf-shaped design. This shape is not only aesthetically pleasing but also effectively reduces air resistance, ensuring stability even in complex environments such as light winds. Through the adjustment of the horizontal adjustment component, the sensor can always maintain the optimal horizontal receiving state, further optimizing the signal reception effect.
[0037] In use, the sensor is first roughly adjusted to the target direction using the coarse adjustment component, then the fine adjustment component is used for precise angle adjustment, and finally the leveling component is used to calibrate the sensor's horizontal state. This step-by-step adjustment method ensures both speed and accuracy. With this device, the sensor's installation angle can be effectively controlled within 15°, significantly reducing signal reception errors and greatly improving data quality. Furthermore, the device's compact overall design makes it easy to carry and install, suitable for long-term monitoring in complex environments such as mines.
