Description

Technical Field

[0001] This utility model relates to the field of mine sensor installation technology, specifically a support mechanism for a level sensor used in mine settlement measurement. Background Technology

[0002] The primary function of a level sensor support mechanism is to provide stable physical support for the sensor, ensuring its reliability and accuracy in harsh mining environments. The support mechanism ensures stable operation of the sensor under ground subsidence, vibration, and other external disturbances caused by mining activities through physical support, reduction of external vibration impacts, and protective functions. The structure of this type of support mechanism generally includes components such as a support rod, base, connectors, and protective cover. The support rod is typically made of high-strength steel or aluminum alloy to ensure sufficient rigidity and strength to withstand potential external loads. The base, as the foundation of the support mechanism, is designed as a heavy-duty structure, usually made of concrete or metal, ensuring stable fixation of the sensor during subsidence or vibration. Connectors are used to firmly connect the various parts and are usually made of corrosion-resistant materials to cope with the corrosive environment of the mining site. However, currently, after the level sensor is assembled in the support mechanism, the operating height and angle of the level sensor are also determined, while the environmental conditions of the mining site are dynamically changing, including fluctuations in groundwater levels and changes in terrain. These changes may alter the optimal measurement height, and once the assembly is fixed at a certain height, it cannot adapt to changes in the environment, thus affecting the accuracy of the measurement. Utility Model Content

[0003] The purpose of this utility model is to provide a support mechanism for a level sensor used in mine settlement measurement. A Y-shaped arc-shaped fork is fixed on the plane to be installed, while a plate is slidably installed into the Y-shaped arc-shaped fork. The level sensor is threaded into the support base. The AC axis angles of the support arm, support base, and level sensor are adjusted by locking pins and rotating shafts, while the height of the level sensor is adjusted by a swing height adjustment structure, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a support mechanism for a level sensor used in mine settlement measurement, comprising a Y-shaped arc-shaped fork and a disc seat slidably installed inside the Y-shaped arc-shaped fork. Two symmetrical square protrusions are integrally formed on the outer wall of the disc seat on the side away from the Y-shaped arc-shaped fork. A rotating shaft is rotatably installed between the two square protrusions. A connecting block is fixed to one end of the rotating shaft. A swing height adjustment structure is provided on the outer wall of the connecting block on the side away from the rotating shaft. A support arm is installed at the movable end of the swing height adjustment structure, and a support seat is installed on one side of the top of the support arm.

[0005] Preferably, a vertical block is integrally formed on one side of the bottom end of the Y-shaped arc-shaped fork, and through holes are provided on both sides inside the vertical block.

[0006] Preferably, a locking pin is installed at the top of one of the square protrusions, and the bottom end of the locking pin extends through to the outside of the other square protrusion.

[0007] Preferably, the inner wall of the Y-shaped arc-shaped fork is provided with an inner edge, the outer peripheral surface of the disc base is provided with a groove that is interference-fitted and slidably inserted with the inner edge, the cross-sectional shape of the inner edge and the groove is trapezoidal, and a baffle is fixed on the upper surface of the disc base.

[0008] Preferably, the swing height adjustment structure includes an L-shaped foot fixed to one side of the outer wall of the connecting block, a U-shaped sleeve provided on one side of the surface of the L-shaped foot, the bottom end of the U-shaped sleeve being fixedly connected to one end of the support arm, a positioning bolt being installed on one end of the surface of the U-shaped sleeve, and one end of the positioning bolt penetrating to the outside of the L-shaped foot and being fitted with a nut.

[0009] Preferably, the support arm and the support base are made of stainless steel, and the support base has an internal threaded hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The support mechanism for a level sensor used in mine settlement measurement, through the design of a Y-shaped arc-shaped fork and a disc base, allows for flexible adjustment of the installation height and angle of the level sensor. This feature enables the sensor to quickly adapt to changes in different environmental conditions. Furthermore, the adjustment of the locking pin and rotating shaft can precisely adjust the installation angle of the level sensor, ensuring that it is perpendicular to the liquid level to be measured or maintained at the optimal measurement angle, reducing measurement errors caused by improper installation. When the water level in the mine area rises or falls rapidly, the height of the support arm, support base, and level sensor can be adjusted as needed through the swing height adjustment structure to keep the sensor in the optimal measurement range, ensuring the reliability of the data.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figure 1-5 An embodiment of this utility model provides a support mechanism for a level sensor used in mine settlement measurement, including a Y-shaped arc-shaped fork 1 and a disc base 2 slidably installed inside the Y-shaped arc-shaped fork 1. Two symmetrical square protrusions 3 are integrally formed on the outer wall of the disc base 2 away from the Y-shaped arc-shaped fork 1. A rotating shaft 5 is rotatably installed between the two square protrusions 3. A connecting block 6 is fixed to one end of the rotating shaft 5. A swing height adjustment structure 7 is provided on the outer wall of the connecting block 6 away from the rotating shaft 5. A support arm 8 is installed on the movable end of the swing height adjustment structure 7, and a support seat 9 is installed on one side of the top of the support arm 8. The support arm 8 and the support seat 9 are made of stainless steel. The support seat 9 has an internal threaded hole.

[0019] A stand block 101 is integrally formed on one side of the bottom end of the Y-shaped arc-shaped fork 1. Both sides of the stand block 101 are provided with through holes 102. The Y-shaped arc-shaped fork 1 is fixed to the mounting plane through the two through holes 102 inside the stand block 101 and bolts to ensure that it does not shift during subsequent operation.

[0020] One of the square protrusions 3 has a locking pin 4 installed at its top. The bottom end of the locking pin 4 extends through to the outside of the other square protrusion 3. The operator manually rotates the shaft 5 to make the shaft 5 rotate, thereby adjusting the AC axis angle of the connecting block 6, the swing height adjustment structure 7, the support arm 8, the support base 9, and other components. Then, the locking pin 4 is used to continuously tighten the two square protrusions 3, thereby fixing the shaft 5 and maintaining the angle of the level sensor.

[0021] The inner wall of the Y-shaped arc-shaped fork 1 is provided with an inner edge 103, and the outer peripheral surface of the disc base 2 is provided with a groove that is interference-fitted with the inner edge 103. The cross-sectional shape of the inner edge 103 and the groove is trapezoidal. A baffle 201 is fixed on the upper surface of the disc base 2. When the Y-shaped arc-shaped fork 1 and the disc base 2 are assembled, the inner edge 103 on the inside of the Y-shaped arc-shaped fork 1 is interference-fitted with the groove on the outer peripheral surface of the disc base 2. At this time, the lower surface of the baffle 201 contacts the upper surface of the Y-shaped arc-shaped fork 1, so that the Y-shaped arc-shaped fork 1 and the disc base 2 are connected. Its detachable structure allows the level sensor and the support mechanism to be separated from the mounting plane together for maintenance, repair and replacement.

[0022] The swing height adjustment structure 7 includes an L-shaped foot 701 fixed on one side of the outer wall of the connecting block 6, and a U-shaped sleeve 702 set on one side of the surface of the L-shaped foot 701. The bottom end of the U-shaped sleeve 702 is fixedly connected to one end of the support arm 8. A positioning bolt 703 is installed on one end of the surface of the U-shaped sleeve 702. One end of the positioning bolt 703 passes through the outside of the L-shaped foot 701 and is fitted with a nut. When adjusting the height of the support arm 8 and the support base 9, the user manually swings the support arm 8 up or down, so that the support arm 8 and the U-shaped sleeve 702 rotate around the positioning bolt 703. After the level sensor is adjusted, the positioning bolt 703 and the nut are used to lock the U-shaped sleeve 702 and the L-shaped foot 701.

[0023] In this embodiment, the operator first needs to select a flat and stable installation location. This location should be close to the liquid to be measured in the mining area to improve the accuracy and timeliness of the measurement. Then, the Y-shaped arc-shaped fork 1 is fixed on the installation surface. The Y-shaped arc-shaped fork 1 serves as the foundation of the entire support structure, and its stability directly affects the working effect of the level sensor. After the Y-shaped arc-shaped fork 1 is fixed, the disc base 2 needs to be slid into the Y-shaped arc-shaped fork 1 until the two are stably assembled. Align the level sensor with the threaded hole of the support base 9, gently rotate and tighten to ensure a secure connection. During this process, avoid excessive force to prevent damage. The sensor structure is now complete, connecting the mechanism to the mounting plane and the level sensor. Operators use locking pin 4 and rotating shaft 5 to adjust the connecting block 6, the swing height adjustment structure 7, the support arm 8, the support base 9, and the AC axis angle of the level sensor. This ensures the level sensor points at the optimal angle to the surface of the liquid being measured. Locking pin 4 ensures the rotating shaft 5 and support arm 8 remain at the set angle during subsequent measurements. The swing height adjustment structure 7 allows for height adjustment of the level sensor, moving it up and down to ensure it is within the optimal measurement range for the liquid. After all installation and adjustments are complete, the entire mechanism should be inspected to ensure all connections are secure and without looseness.
