Description

Technical Field

[0001] This utility model relates to the field of surface monitoring technology, and in particular to a surface deformation monitoring device for coal mine subsidence areas. Background Technology

[0002] During coal mining, after the underground coal seam is extracted, the rock strata and surface above the goaf gradually move and deform, forming a subsidence area. Accurate monitoring of surface deformation in coal mine subsidence areas is crucial for ensuring the safety of surrounding buildings and infrastructure, as well as for rational land use planning. Currently, GPS positioning technology, with its advantages of high precision, all-weather operation, and real-time performance, has become one of the main methods for monitoring surface deformation in coal mine subsidence areas. In practical applications, the antenna of the GPS positioning device, as a key component for receiving satellite signals, directly affects the accuracy and reliability of the monitoring data.

[0003] However, the antenna is susceptible to environmental factors such as dust, snow, and ice. Dust can adhere to the antenna surface, reducing signal reception sensitivity; snow can obstruct the antenna, hindering normal signal transmission; and ice can alter the antenna's physical structure and electrical performance, leading to increased signal reception errors or even signal interruption. Most existing GPS positioning devices lack effective protection and cleaning mechanisms. When faced with these environmental problems, manual cleaning and maintenance are often required periodically. However, manual cleaning is not only inefficient and costly, but also poses significant safety risks under some severe weather conditions, making it difficult to guarantee the continuity and stability of monitoring work. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a surface deformation monitoring device for coal mine subsidence areas. This device can remove dust, snow, and ice from the antenna of the GPS locator, thus avoiding the impact of environmental factors on the detection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A surface deformation monitoring device for coal mine subsidence areas includes a frame, a U-shaped support plate fixedly connected to the upper side wall of the frame, an antenna mounted on the upper horizontal part of the U-shaped support plate, a control box mounted on one side of the frame, and a GPS locator installed inside the control box; a cleaning mechanism, the cleaning mechanism including a hollow ring disposed outside the antenna, an annular groove formed on the inner side wall of the hollow ring, an electric telescopic rod fixedly connected to the lower horizontal part of the U-shaped support plate, the telescopic end of the electric telescopic rod passing through the upper horizontal part of the U-shaped support plate and fixedly connected to the lower end of the hollow ring, an adjustable hot air fan fixedly connected to the lower end of the U-shaped support plate, the air outlet of the adjustable hot air fan being connected to a second branch pipe, and the other end of the second branch pipe being connected to the hollow ring.

[0006] Preferably, the second branch pipe is a flexible pipe.

[0007] Preferably, solar panels are installed on the upper part of the side wall of the frame.

[0008] Preferably, the solar panel is installed at an angle, a hollow strip is fixedly connected to the right side of the solar panel, a strip groove is provided on the left side of the hollow strip, the air outlet of the adjustable hot air blower is connected to a first branch pipe, and the other end of the first branch pipe is connected to the interior of the hollow strip.

[0009] Preferably, the GPS locator is electrically connected to the antenna.

[0010] Preferably, a power module is installed inside the control box, and the power module is electrically connected to the solar panel.

[0011] Compared with the prior art, the advantages of this utility model are as follows: 1. The solar panels installed at an angle on the frame absorb solar energy and convert it into electrical energy, which is then transmitted to a power module consisting of a battery and a rectifier and voltage regulator circuit for storage, thus powering the device. This saves energy, is environmentally friendly, and reduces operating costs.

[0012] 2. When the adjustable hot air blower is blowing air at room temperature, the air passes through the first branch pipe, hollow strip, and strip groove to clean the solar panel; the electric telescopic rod drives the hollow ring to move, and the air passes through the second branch pipe to blow the antenna out of the annular groove, which is clean and efficient.

[0013] 3.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-4 A surface deformation monitoring device for coal mine subsidence areas includes a frame 1, a U-shaped support plate 6 fixedly connected to the upper side wall of the frame 1, an antenna 7 installed at the upper horizontal part of the U-shaped support plate 6, a control box 2 installed on one side of the frame 1, and a GPS positioning device 3 installed inside the control box 2. Using the GPS positioning device 3 to measure surface subsidence is a commonly used measurement method. The core principle is to use satellite signals to determine the location of the receiver and analyze the location changes through long-term continuous observation. The system also includes a cleaning mechanism, which includes a hollow ring 8 located outside the antenna 7. The inner wall of the hollow ring 8 has an annular groove 13. An electric telescopic rod 9 is fixedly connected to the lower horizontal part of the U-shaped support plate 6. The telescopic end of the electric telescopic rod 9 passes through the upper horizontal part of the U-shaped support plate 6 and is fixedly connected to the lower end of the hollow ring 8. An adjustable hot air blower 10 is fixedly connected to the lower end of the U-shaped support plate 6. The adjustable hot air blower 10 is a blower with an electric heating wire and can be selected to be either heated or at room temperature. The air outlet of the adjustable hot air blower 10 is connected to a second branch pipe 12. The other end of the second branch pipe 12 is connected to the hollow ring 8. The second branch pipe 12 is a soft pipe with a certain length. The GPS locator 3 is electrically connected to the antenna 7. The frame 1 has a solar panel 4 installed on the upper side wall. The solar panel 4 is installed at an angle. A hollow strip 5 is fixedly connected to the right side of the solar panel 4. A strip groove 14 is provided on the left side of the hollow strip 5. The air outlet of the adjustable hot air blower 10 is connected to a first branch pipe 11. The other end of the first branch pipe 11 is connected to the inside of the hollow strip 5. A power module is installed inside the control box 2. The power module is electrically connected to the solar panel 4. The power module consists of a battery and a rectifier and voltage regulator circuit module, which can store solar energy. It should be noted that a controller is also provided to control the above-mentioned components.

[0018] In this invention, the GPS locator 3 inside the control box 2 receives satellite signals via antenna 7, uses these signals to determine the receiver's location, and analyzes position changes through long-term continuous observation to measure surface subsidence. Solar panels 4, installed at an angle on the upper side wall of the frame 1, absorb solar energy and convert it into electrical energy, which is then transmitted to the power module inside the control box 2. The power module consists of a battery and rectifier / voltage regulator circuit modules, storing electrical energy and supplying power to the electrical components of the entire device.

[0019] When cleaning the solar panel 4 or antenna 7 is required, the adjustable hot air blower 10 is set to normal temperature blowing mode. The air generated by the blower enters the hollow strip 5 through the first branch pipe 11 and then blows out from the strip groove 14 on the left side of the hollow strip 5 to clean the surface of the solar panel 4, removing dust and other impurities. At the same time, the electric telescopic rod 9, which is fixedly connected to the horizontal part below the U-shaped support plate 6, is activated and extends once. Its telescopic end extends upward, driving the hollow ring 8 to move upward, so that the antenna 7 is located in the annular groove 13 opened on the inner side wall of the hollow ring 8. The air generated by the telescopic rod enters the hollow ring 8 through the second branch pipe 12 and blows out from the annular groove 13 to clean the surface of the antenna 7. After cleaning, the telescopic end of the electric telescopic rod 9 is retracted, driving the hollow ring 8 back to its initial position. It should be noted that if de-icing or snow removal is required for the antenna 7 and solar panel 4, the hot air mode can be selected when blowing air.
