Description

Technical Field

[0001] The utility model relates to the technical field of mine slope settlement monitoring. Background Art

[0002] In mine safety, for the settlement monitoring technology of mine slope settlement, that is, the vertical displacement monitoring of the slope, it is necessary to regularly measure the elevation change of the working point in the deformation monitoring.

[0003] With the development of science and technology, the methods of mine slope settlement monitoring are also changing with each passing day. For example, the leveling measurement technology is to use the horizontal line of sight provided by the level to measure the height difference between two points on the ground, and then calculate the elevation of another point based on the elevation of the known point. Through this method, the settlement of the slope can be monitored.

[0004] For another example, the trigonometric leveling measurement technology is an indirect elevation measurement method that uses a rangefinder to measure the distance between two points and, based on the principle of similar triangles, sets up a measuring station at one point to observe the vertical angle or zenith distance to the other point to solve the height difference between the two points.

[0005] The above two technical routes have their own advantages and disadvantages. Based on the current situation of the requirements for mine slope settlement monitoring, the utility model provides a mine slope settlement monitoring device with a new structure. Summary of the Utility Model

[0006] In order to solve the deficiencies of the prior art, the utility model provides a mine slope settlement monitoring device to solve the problem that there is a lack of a monitoring device based on vision technology in the existing settlement monitoring technical route.

[0007] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0008] The mine slope settlement monitoring device includes a top pile, a bottom pile, a steel strand, an observation pile, a fixed piece and a movable piece. Among them, the top pile and the bottom pile are respectively installed at the top and bottom of the slope, the top pile and the bottom pile are connected by a steel strand, a fixed piece is installed on the steel strand, an observation pile is fixedly installed on the slope below the fixed piece, a movable piece is arranged at the top of the observation pile, different colors are set on the upper surfaces of the fixed piece and the movable piece for distinction, and the movable piece and the fixed piece are in an overlapping state in the initial state.

[0009] The observation pile is preferably a screw pile, and a movable piece is formed at the top of the observation pile by welding a circular stainless steel sheet.

[0010] The observation pile is perpendicular to the slope.

[0011] The steel strand includes two vertical and one horizontal steel strands, forming an H-shaped arrangement.

[0012] The stationary plate is a stainless steel plate with a thickness of not less than 1 mm.

[0013] The top pile and the bottom pile are reinforced by stay cables.

[0014] The top pile and the bottom pile are bored cast-in-place piles, which have sufficient stability.

[0015] The stationary plate and the moving plate have a circular contour, and four steel strand fixing holes are arranged around the stationary plate to facilitate the installation and positioning of the stationary plate.

[0016] The stationary plate is set to be black, and the moving plate is set to be red, with an obvious color difference between the two.

[0017] It also includes a photoelectric alarm module fixed on the upper surface of the stationary plate.

[0018] The photoelectric alarm module includes a photovoltaic power generation panel, a micro lithium battery, a circuit board, and LED lamp beads. Among them, a magnetic normally open switch is arranged in the circuit board, and a strong magnetic block is arranged on the moving plate. When the overlapping area of the stationary plate and the moving plate meets the set requirements, the photoelectric alarm module will not give an audible or visual alarm. When the overlapping area of the stationary plate and the moving plate exceeds the set requirements, the magnetic normally open switch in the photoelectric alarm module closes and gives an audible and visual alarm synchronously.

[0019] Preferably, the diameter of the stationary plate is significantly larger than that of the moving plate, so that the moving plate has a complete covering effect in the initial state, that is, in the front view, the moving plate is completely covered under the stationary plate.

[0020] The penetration depth of the observation pile is 0.5 m to 1 m.

[0021] The penetration depth of the top pile and the bottom pile is not less than 10 m to maintain sufficient fixing force, thus ensuring the relative stability of the steel strand and the stationary plate.

[0022] The beneficial effects of the present utility model are:

[0023] By arranging the stationary plate and the moving plate with contrasting colors on the slope surface, the local sliding condition of the slope surface can be quickly detected. Among them, the moving plate represents the stability condition of the slope surface, and the stationary plate provides an observation reference, and this reference is connected to the top pile and the bottom pile through steel strands, which has a higher reference significance.

[0024] With visual observation elements, combined with manual inspection and drone inspection, this device can quickly and efficiently conduct settlement observation and collect relevant data to provide technical guidance for mine safety. Description of the Drawings

[0033] Refer to Figures 1 to 2 , the mine slope settlement monitoring device, which includes a top pile 01, a bottom pile 02, a steel strand 03, an observation pile 04, a fixed piece 05, a moving piece 06, and a photoelectric alarm module 07. Among them, the top pile and the bottom pile are respectively installed at the top and bottom of the slope 00 and are reinforced with stay cables. The above-mentioned top pile and bottom pile are bored cast-in-place piles and have sufficient stability. A steel strand 03 is used to connect between the top pile 01 and the bottom pile 02, and a plurality of fixed pieces 05 are serially installed on the steel strand. The fixed piece 05 is an independent module and is made of stainless steel stamping steel plate. Specifically, the fixed piece is made of stainless steel plate with a thickness of not less than 1 mm. The fixed piece 05 is fixed on the steel strand through fasteners. To prevent the fixed piece 05 from flipping, adjacent fixed pieces in the horizontal direction are connected by wires or steel strands. In this embodiment, the numbers of the top pile 01 and the bottom pile 02 are two respectively, that is, two top piles are located at the top of the slope, and two bottom piles are located at the bottom of the slope. The above-mentioned steel strand includes two vertical ones and one horizontal steel strand, forming an H-shaped layout. And five fixed pieces 05 are distributed on the H-shaped steel strand.

[0034] Furthermore, the above-mentioned fixed piece has a circular contour, and four steel strand fixing holes are provided around the fixed piece to facilitate the installation and positioning of the fixed piece.

[0035] Refer to Figure 3, an observation pile 04 is fixedly driven into the slope below each fixed piece 05, and the observation pile 04 is preferably a spiral pile, and a moving piece 06 is set on the top of the observation pile, for example, a moving piece is formed on the top of the observation pile 04 by welding a circular stainless steel sheet. The so-called moving piece means that the moving piece 06 is vertically welded on the top of the observation pile. During construction, the observation pile 04 is driven into the slope, and the observation pile and the slope are kept in a vertical relationship, that is, the moving piece and the slope are kept in a parallel relationship. When the slope is disturbed and the position is shifted, the moving piece 06 will shift with the displacement of the observation pile. The above-mentioned moving piece and fixed piece are in an overlapping state in the initial state, for example, a circular fixed piece and a moving piece with a diameter of 20 cm. When the slope near the observation pile undergoes local settlement or sliding, the moving piece and the fixed piece no longer overlap, that is, a relative shift occurs. Preferably, the upper surfaces of the fixed piece and the moving piece are set to different colors, for example, the fixed piece is set to black and the moving piece is set to red, and there is an obvious color difference between the two.

[0036] Preferably, the diameter of the stator is significantly larger than the diameter of the moving plate, so that the moving plate is completely covered in the initial state, that is, the moving plate is completely covered under the stator when viewed from the front.

[0037] The above-mentioned observation pile 04 is buried shallowly, preferably 0.5 to 1 meter, so that the observation pile can follow the slope gravel or soil layer. The above-mentioned top pile and bottom pile are buried in the ground using cast-in-place piles, and the burial depth is not less than 10 meters to maintain sufficient stability, thereby ensuring the relative stability of the steel strand and the stator.

[0038] Preferably, the above-mentioned fixed plate 05 is integrated with a photoelectric alarm module 07, which includes a photovoltaic power generation panel, a micro lithium battery, a circuit board, and LED lamp beads, and forms a complete set of visual alarm circuits. Specifically, a magnetic normally open switch is arranged in the circuit board, and a strong magnetic block is arranged on the movable plate. When the overlapping area of ​​the fixed plate and the movable plate meets the set requirements, the photoelectric alarm module 07 will not generate sound and light alarms. When the overlapping area of ​​the fixed plate and the movable plate exceeds the set requirements, for example, the threshold is set to a gap of greater than or equal to 2 cm between the movable plate and the fixed plate in the horizontal direction. When a gap of greater than 2 cm is generated between the movable plate and the fixed plate in the horizontal direction, the magnetic normally open switch in the photoelectric alarm module 07 is closed, and sound and light alarms are synchronously emitted. The photoelectric alarm module is fixed on the fixed plate, and the black color of the photovoltaic power generation panel itself is used to form an identification color.

[0039] This technology is used to observe the deformation of the slope surface of the mine. It is the simplest and most direct macro-monitoring method. The monitoring base points of the device are selected at the top and bottom of the slope and are relatively stable in combination with cast-in-place piles. It is directly related to the accuracy of the monitoring results.

[0040] This technology can quickly detect local shape changes of slopes by comparing the stationary and moving plates of different colors, transforming the imperceptible changes into perceptible visual changes, and can monitor the slope body well.

[0041] The inspection plan for this device is as follows:

[0042] Manual inspection. Manual inspection is a regular task. People are arranged to conduct inspections every day. During the inspection, observe the overlapping degree between the stationary and moving plates. Theoretically, within a range of 100 meters, if red cannot be visually observed, it means that the coincidence degree of the moving and stationary plates is good. Refer to Figure 4 , and it is in a non-landslide state. If a circular red moving plate is observed, it means that a small local landslide is likely to occur. Refer to Figure 5 , and a more detailed inspection should be carried out. If a large area of red moving plates is observed, and at the same time, individual optoelectronic alarm modules 07 give audible and visual alarms. Refer to Figure 6 , it means that the landslide risk coefficient is very high, and it is necessary to report to the superior unit and formulate strategies. Therefore, analyze the deformation and failure trend of the slope body by observing the overlapping degree and change law of the moving and stationary plates.

[0043] Inspection by drone 08. Different from manual inspection, use the 3D vision recognition system on the drone for observation. Fly the drone directly above the slope and use the photo-taking function. The overlapping degree and change law of the moving and stationary plates can be obtained through artificial intelligence. Through data processing and analysis, analyze the geometric appearance changes between multiple observation points on the slope surface, draw the horizontal and vertical displacement changes of each point on the slope surface, understand the sliding range and sliding conditions of the slope, and provide early warning information.

[0044] The above-described embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those skilled in the relevant art to the present invention should fall within the protection scope determined by the claims of the present invention.
