Abstract
Description
Technical Field
[0001] This utility model relates to the field of radar detection technology, and in particular to a radar exploration airspace positioning support device. Background Technology
[0002] Ground-penetrating radar (GPR) uses ultra-high frequency electromagnetic waves to detect the distribution of underground media. Its basic principle is as follows: a transmitter emits a pulsed electromagnetic wave signal with a center frequency of 12.5 MHz to 1200 MHz and a wavelength of 0.1 ns through a transmitting antenna. When this signal encounters a target in the rock strata, it generates a reflected signal. The direct and reflected signals are input to the receiver through a receiving antenna, amplified, and displayed on an oscilloscope. The presence or absence of a reflected signal indicates the presence of the target; the distance to the target can be roughly calculated based on the arrival time lag of the reflected signal and the average reflected wave velocity of the target object.
[0003] When using radar to conduct geological exploration of coal mine goaf areas, it is necessary to support and reinforce the goaf areas to prevent them from collapsing before radar exploration can be carried out.
[0004] A search revealed Chinese Patent Publication No. CN220059605U, which discloses a hydraulic support device for coal mining. The device includes a support roof plate, electric hydraulic cylinders, a base plate, side support components, a top support component, a servo motor, and positioning holes. Electric hydraulic cylinders are installed at both ends of the bottom of the support roof plate and are connected to the servo motor. The base plate is installed at the bottom of the electric hydraulic cylinders and has multiple positioning holes. Side support components are located at both ends of the support roof plate, and a top support component is also installed above the support roof plate. This device can effectively support weak parts of the coal mine sidewalls, improving the safety of the coal mine tunnel, and can also effectively reduce the noise generated by the support equipment. However, in actual use, due to the pressure on the top of the coal mine being affected by the rock strata, the pressure distribution in different parts is uneven. Therefore, this device can only provide support and cannot provide additional support for areas under strong local pressure, reducing its practicality. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a radar exploration airspace positioning support device, comprising a support plate 1 and two bases 5. The support plate 1, as an important component of the entire support equipment, connects to the top plate 3 and transmits the pressure borne by the top plate 3 to the supporting structure below. The top of the support plate 1 is fixedly connected to the top plate 3, directly contacting the top plate 3 of the mining face and bearing the pressure transmitted from the top plate 3. The top of the top plate 3 has multiple seepage holes 4, allowing water seeping from the top of the mining roadway to flow downwards through these holes. The tops of the two bases 5 are each fixedly connected to a hydraulic rod 6, which can be extended and retracted according to the actual roadway height and the condition of the top plate 3 to adapt to different working environments. The tops of the two hydraulic rods 6 are fixedly connected to support seats 7, providing a support platform for the support plate 1, and the height can be adjusted by extending and retracting the hydraulic rods 6. The bottom left and right sides of the support plate 1 are each fixedly connected to two T-shaped rods 8. The tops of the two support seats 7 are each provided with T-shaped grooves 9, which cooperate with the T-shaped grooves 9 on the top of the support seats 7 to achieve the horizontal adjustability of the support plate 1. The multiple T-shaped rods 8 Each support plate 7 is slidably connected to its corresponding T-slot 9. Two bolts 10 are threaded onto the front side of the outer wall of each support plate 7. Multiple bolts 10 are threaded onto their respective T-shaped rods 8. After the support plate 1 is positioned, it is securely fixed. Limiting plates 12 are fixedly connected to the front and rear sides of the bottom of the support plate 1, providing sliding limits for the reinforcing plate 13. Reinforcing plates 13 are slidably connected to the left and right sides of adjacent limiting plates 12. When the mining face is under strong local pressure, this enhances the local bearing capacity of the support plate 1. Reinforcing plates 13 are slidably connected to adjacent sides of the two support plates 7. A rotating seat 11 is fixedly connected to provide a rotating connection point for the hydraulic cylinder 14. The inner walls of the two rotating seats 11 are rotatably connected to the hydraulic cylinder 14, which can be extended and retracted according to the pressure to provide support for the reinforcing plate 13. The top rod ends of the two hydraulic cylinders 14 are respectively hinged to the lower end face of the corresponding reinforcing plate 13, so that the hydraulic cylinder 14 can effectively transmit the supporting force to the reinforcing plate 13. A radar 23 is fixed to the lower end face of one of the reinforcing plates 13. A drainage mechanism 2 is provided at the bottom of the support plate 1. The drainage mechanism 2 is used to drain the seepage water in the goaf.
[0031] Specifically, two bases 5 are placed on the ground to provide stable support for the equipment. The hydraulic rods 6 on top are telescopic, allowing the support base 7 to be adjusted to a suitable position according to the tunnel height and roof condition 3, providing support for the support plate 1. The T-shaped rods 8 on the left and right sides of the bottom of the support plate 1 are slidably connected to the T-shaped grooves 9 on the top of the support base 7, facilitating installation and fine-tuning. Then, the bolts 10 threaded to the front of the outer wall of the support base 7 are tightened to the T-shaped rods 8 to fix the support plate 1 and prevent displacement. The roof 3 at the top of the support plate 1 has seepage holes 4 that allow tunnel seepage water to flow into the support plate 1 and then be discharged through the drainage mechanism 2. Mechanism 2 is responsible for draining seepage water from the roadway and ensuring a stable support environment. The limiting plates 12 on the front and rear sides of the bottom of the support plate 1 cooperate with the reinforcing plate 13 that is slidably connected in the middle. When the local pressure is strong, the hydraulic cylinder 14 rotatably connected in the rotating seat 11 on the adjacent side of the support seat 7 extends and retracts according to the pressure. Its top end is rotatably connected to the reinforcing plate 13 to provide support for the reinforcing plate 13, enhance the local load-bearing capacity of the support plate 1, solve the problem that the existing technology cannot provide additional support for local high-pressure areas, improve the practicality of the device, and achieve effective support and drainage for the mining face by the cooperation of all components, ensuring mining safety.
[0032] Reference Figure 4 and Figure 5 The drainage mechanism 2 includes two water tanks 201 to temporarily store seepage water flowing down from the support plate 1. The tops of the two water tanks 201 are fixedly connected to the front and rear sides of the bottom of the support plate 1, respectively. Multiple drainage outlets 202 are provided on the front and rear sides of the bottom of the inner wall of the support plate 1 to provide a channel for seepage water in the support plate 1, so that the seepage water can flow into the water tanks 201. Filter screens 203 are fixedly connected to the inner walls of the two water tanks 201 to filter the seepage water flowing into the water tanks 201 and intercept impurities in the water. Drainage pipes 204 are connected to the left and right sides of the bottom of the two water tanks 201 to discharge the filtered water from the water tanks 201. Control valves 205 are provided on the outer walls of the multiple drainage pipes 204 so that the operator can adjust the drainage according to the actual situation, such as the water accumulation in the tunnel and the drainage needs.
[0033] Specifically, the tops of the two water tanks 201 are fixed to the front and rear sides of the bottom of the support plate 1, respectively, to collect the seepage water flowing down from the support plate 1. Multiple drain outlets 202 on the front and rear sides of the bottom of the inner wall of the support plate 1 provide channels for the seepage water to flow smoothly into the water tanks 201. The filter screen 203 on the inner wall of the water tank 201 can filter the seepage water, intercepting impurities and particles that may be carried in the water, preventing them from clogging the subsequent drain pipe 204 or damaging related equipment. The drain pipes 204 connected to the left and right sides of the bottom of the water tank 201 are responsible for discharging the filtered water. The control valve 205 installed on the outer wall of the drain pipe 204 gives the operator the ability to flexibly control the drainage. The operator can adjust the outflow speed and flow rate of the water through the control valve 205 according to the actual situation such as the water accumulation in the tunnel and the drainage needs, so as to achieve precise control of the drainage process. All components work closely together to complete a series of processes from collecting seepage water and filtering impurities to controlled discharge, effectively ensuring that the environment around the mine face support equipment is dry and ensuring the stable operation of the equipment.
[0034] Reference Figure 1 , Figure 2 and Figure 5 The inner wall of the support plate 1 is fixedly connected with multiple reinforcing ribs 15, and the top of each reinforcing rib 15 is fixedly connected to the top plate 3, which enhances the overall structural strength of the support plate 1 and the top plate 3 and improves the load-bearing capacity. The top of the top plate 3 is fixedly connected with multiple tapered rods 16, which are inserted into the rock above the top plate 3 to increase friction and stability. The spacing between adjacent tapered rods 16 is equal. The bottom of each of the two bases 5 is fixedly connected with anti-slip pads 17 to increase friction with the ground. The front and rear sides of the top of each of the two bases 5 are threaded with multiple fixing bolts 18. The bottom ends of the multiple fixing bolts 18 pass through the corresponding anti-slip pads 17 and are inserted into the ground to further fix the equipment and prevent it from shifting during mining.
[0035] Specifically, the reinforcing ribs 15 on the inner wall of the support plate 1 are connected to the top plate 3 to enhance the overall structural strength of the support plate 1 and the top plate 3 and improve the load-bearing capacity. The tapered rods 16 at equal intervals on the top of the top plate 3 are inserted into the rock mass above the top plate 3 to increase friction and stability. The anti-slip pads 17 at the bottom of the base 5 increase the friction with the ground. The fixing bolts 18 with threads on the top of the base 5 penetrate the anti-slip pads 17 and are inserted into the ground to further fix the equipment and prevent it from shifting during mining.
[0036] Reference Figure 1 , Figure 2 and Figure 3Each of the two hydraulic rods 6 on the left and the two hydraulic rods 6 on the right is fixedly connected to a lamp holder 19 to support the lighting lamp 20. Multiple lighting lamps 20 are fixedly connected to the inner walls of the two lamp holders 19 to illuminate the mining face and facilitate operation. A vibration detector 21 is fixedly connected to the bottom left of the support plate 1 to monitor the vibration of the equipment. An alarm 22 is fixedly connected to the bottom right of the support plate 1 to issue an alarm. The vibration detector 21 and the alarm 22 are electrically connected.
[0037] Specifically, the lamp holders 19 on the adjacent sides of the hydraulic rods 6 on the left and right sides provide support for the lighting lamps 20. Multiple lighting lamps 20 illuminate the mining face to facilitate operation. The vibration detector 21 on the bottom left of the support plate 1 monitors the vibration of the equipment. Once an abnormal vibration is detected, it immediately transmits the signal to the alarm 22 electrically connected on the right side to issue an alarm.
[0038] Working Principle: In the mining roadway, the equipment is first placed on the ground via two bases 5, providing a stable support foundation for the entire device. The hydraulic rods 6 on the top of the bases 5 can be extended and retracted according to the actual roadway height and roof conditions 3 to adapt to different working environments. The support base 7 is adjusted to a suitable height to provide reliable support for the support plate 1. The T-shaped rods 8 on the left and right sides of the bottom of the support plate 1 are slidably connected to the T-shaped grooves 9 on the top of the support base 7. This design allows the support plate 1 to have a certain degree of horizontal adjustability, facilitating equipment installation and fine-tuning. After installation, the bolts 10 on the front of the outer wall of the support base 7 are tightened to connect with the corresponding T-shaped rods 8, thus firmly fixing the support plate 1 to the support base 7 and preventing it from slipping during operation. When displacement occurs, the top plate 3 is fixed to the top of the support plate 1. Multiple seepage holes 4 opened on its top allow seepage water from the top of the roadway to flow through these holes onto the support plate 1, and then flow to the drainage mechanism 2. The drainage mechanism 2 can effectively drain the seepage water in the roadway, avoid the impact of water accumulation on the support, and ensure the stability of the support environment. When the mining face is under strong local pressure, the reinforcing plate 13 between the limiting plates 12 on the front and rear sides of the bottom of the support plate 1 plays a role. The hydraulic cylinder 14 is rotatably connected in the rotating seat 11 on the adjacent side of the two support seats 7. Its top end is rotatably connected to the reinforcing plate 13. The hydraulic cylinder 14 can be extended and retracted according to the pressure, providing support for the reinforcing plate 13, thereby enhancing the local bearing capacity of the support plate 1 and providing additional support for the parts under strong local pressure.
[0039] During the mining process, water seepage from the support face in the roadway flows downwards through seepage openings 4 at the top of the roof 3, eventually entering the support plate 1. Multiple drainage outlets 202 on the front and rear sides of the bottom of the inner wall of the support plate 1 provide channels for the water entering the support plate 1, allowing it to flow into two water tanks 201 located on the front and rear sides of the bottom of the support plate 1. The water tanks 201 temporarily store and further treat the water during the drainage process. A filter screen 203 fixedly connected to the inner wall of the water tank 201 filters the water flowing into it. The filtration system effectively intercepts these impurities, ensuring that the outflowing water is relatively clean. The filtered water flows out from the drain pipes 204 connected to the left and right sides of the bottom of the water tank 201. Each drain pipe 204 is equipped with a control valve 205 on its outer wall. The control valve 205 provides flexible control for the entire drainage process. Operators can control the outflow speed and flow rate of the water in the water tank 201 by operating the control valve 205 according to the actual situation, such as the water accumulation in the tunnel and the drainage needs. This effectively realizes the collection, filtration and discharge control of seepage water in the tunnel, ensuring the dryness and stability of the working environment of the mine face support equipment.
