Description

[0002] Geographical exploration and surveying devices are widely used in fields such as geographical information collection, measurement, mapping, and analysis, such as geographical exploration, civil engineering, environmental monitoring, map production, and land management. For example, the patent with the publication number CN211783463U introduces a support device for a geographical exploration and surveying instrument, including a placement box. One side and the top of the placement box are both open, and hanging grooves are provided at the tops of the two adjacent sides of the open side of the placement box. An L-shaped folding plate is rotatably installed on the open side of the placement box, a soft magnetic sheet is provided at the other end of the folding plate, and a telescopic rod is vertically and fixedly installed in the middle of the placement box. The upper part of the telescopic part of the telescopic rod is rotatably installed with a square block through a bearing, and a surveying and mapping instrument body is horizontally and fixedly installed at the top of the telescopic rod. This utility model places the surveying and mapping instrument and the support device in the placement box, which can not only be conveniently carried in the wild, but also the surveying and mapping instrument is very convenient to retrieve; However, during use, geographical exploration and surveying devices usually need to maintain a high degree of stability, and their measurement results depend on accurate data such as angles, distances, and positions.

[0012] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art: First, the drive shaft of the rotation driving member drives the lifting disc to reciprocate in the air injection barrel: when the lifting disc rises, compressed air is input into the airbag through the one-way pressure relief valve; when it descends, external air is inhaled through the one-way valve to realize continuous inflation and stable air pressure of the airbag. When the support sinks due to soft ground, the rotating backing plate slides up with the support, compressing the space of the corrugated expansion pipe, resulting in dynamic changes in the air pressure in the gas cylinder. The pressure detection element monitors the air pressure in real time and triggers the alarm at the corresponding position through the controller to accurately locate the support failure point. This design effectively identifies the support deviation or overall settlement through the air pressure feedback mechanism, ensuring the adaptive stability of the surveying device in complex terrains.

[0013] Second, the dust-proof protective cover divides the air flow into multiple paths through a shunt pipe, respectively flushing the dust on the surface of the protective glass and in the integrated groove. After the high-speed air flow removes the attachments on the lens, the dust is sucked into the dust collection box by negative pressure, and the clean air is discharged after being filtered by the filter cotton. The cooperative design of the conical collection box and the dust discharge port realizes the directional aggregation and cleaning of dust, avoiding secondary pollution. The protective glass adopts a clamping groove installation structure, which is convenient for quick replacement and maintenance. This component combines air flow circulation and physical filtration, significantly reducing the impact of dust on the survey accuracy, while reducing the manual cleaning frequency and meeting the needs of long-term field operations. At the same time, the air flow of the air injection component is guided to the nozzle through a shunt, continuously air-cooling and dissipating heat for the rotary drive component to avoid overheating and damage of the equipment.

Detailed Embodiment

[0017] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Embodiment: Refer to Figures 1 to 9 , a portable geological exploration and surveying and mapping device, comprising: A surveying and mapping component 1, a first rotating head 101 is rotatably installed on the lower end surface of the surveying and mapping component 1, a telescopic connecting rod 103 is fixedly installed on the lower end surface of the first rotating head 101, and a plurality of brackets 102 are rotatably installed on the outer wall of the first rotating head 101; An air injection assembly 2, the air injection assembly 2 includes an air injection barrel 201 arranged below the surveying and mapping component 1, a lifting disc 204 is arranged on the inner wall of the air injection barrel 201, the lifting disc 204 is driven to slide up and down airtightly on the inner wall of the air injection barrel 201, and a plurality of airbags 211 are arranged in a circumferential array on the outer wall of the air injection barrel 201; Support detection component 3, the support detection component 3 includes a rotating backing plate 305 slidably mounted on the outer wall of the bracket 102. A corrugated expansion tube 310 is provided at the upper end of the rotating backing plate 305. A plurality of gas cylinders 302 are provided below the air injection barrel 201. A pressure detection element is provided in the gas cylinder 302. The pressure detection element is an existing device, a sensor or device for measuring pressure changes in an object or environment, widely used in various industrial, experimental and automated systems. A capacitive pressure sensor can be used. The capacitive pressure sensor measures pressure by causing a change in capacitance due to pressure and is commonly used in measurement occasions with high precision requirements. The pressure detection element is electrically connected to a controller; The airbag 211 is communicated with the corrugated expansion tube 310 and the gas cylinder 302 through the air outlet pipe 206 and the air inlet pipe 304 respectively.

[0020] Refer to Figures 1 to 4The lower end of the telescopic connecting rod 103 is fixedly installed with a connecting plate 212, and a plurality of slide grooves are provided in the connecting plate 212, and the slide grooves cooperate with the bracket 102. A plurality of arc-shaped slide seats 209 are fixedly installed in a circumferential array on the upper end surface of the connecting plate 212, and an arc-shaped shift rod 210 is slidably installed in the arc-shaped slide seat 209. The gas injection barrel 201 is fixedly connected to the connecting plate 212, and at least one non-return valve 205 is embedded on the outer wall of the gas injection barrel 201 and above the lifting disc 204. The upper circumferential array is connected with a plurality of air outlet pipes 206, and a one-way pressure relief valve 207 is fixedly installed on the inner wall of the air outlet pipe 206. The one-way pressure relief valve 207 is an existing device, which mainly acts on the valve core to be pushed open when the fluid pressure exceeds the set value, allowing the excess fluid to be discharged in one direction through the pressure relief port. This can effectively prevent the lifting disc 204 from lifting slowly and entering the air bag 211. The air cannot provide enough air to enter the bellows telescopic tube 310 and the gas tank 302, causing a pressure difference inside them. At the same time, in the outdoor When the power supply is sufficient, the rotary drive member 202 is driven at a faster speed to make the lifting disc 204 rise and fall quickly to deliver the external air into the airbag 211. The air outlet pipe 206 is connected to the airbag 211. A plurality of support frames 208 are fixedly installed in a circular array on the lower end surface of the connecting disc 212. The lower end of the support frame 208 is fixedly connected to the gas injection barrel 201. The lower end surface of the gas injection barrel 201 is fixedly installed with a rotary drive member 202. The rotary drive member 202 can adopt a motor in the prior art. This is a mature existing technology. The technology is not elaborated in detail here. The rotating drive member 202 needs to be driven by an external power source. When in use, it is necessary to carry a portable power source, such as a portable battery pack or a portable generator. The output end of the rotating drive member 202 passes through the gas injection barrel 201 and is fixedly installed with a shaft 203. The shaft 203 is rotatably connected to the gas injection barrel 201. A reciprocating thread groove is provided on the peripheral side wall of the shaft 203. The inner wall of the lifting disc 204 is embedded with a vertex ball, and the lifting disc 204 is slidably connected to the reciprocating thread groove through the vertex ball.

[0021] Reference Figures 4 to 7, two chutes 318 are symmetrically arranged on the outer wall of the support 102. Two chucks 306 are symmetrically and rotatably installed on the inner wall of the rotating cushion plate 305. The chucks 306 are slidably connected to the chutes 318. A sleeve 307 is fixedly installed on the inner wall of the rotating cushion plate 305 at a position corresponding to the chuck 306. A coil spring 308 is arranged in the sleeve 307. The coil spring 308 is a spiral torsion spring, which is used to provide a reset torque between the rotating cushion plate 305 and the support 102. The inner and outer ends of the coil spring 308 are respectively fixedly connected to the chuck 306 and the sleeve 307. When the support 102 is inserted into the soil, the rotating cushion plate 305 is flipped so that its lower end surface contacts the ground. During the process of flipping the rotating cushion plate 305, the coil spring 308 will be wound up, so that the rotating cushion plate 305 contacts the soil surface. A fixed seat 309 is fixedly installed on the upper end surface of the rotating cushion plate 305. A first ventilation groove is opened in the fixed seat 309. The upper end surface of the fixed seat 309 is fixedly connected to a corrugated expansion pipe 310. An upper joint 311 is fixedly installed on the upper end surface of the corrugated expansion pipe 310. A second ventilation groove is opened in the upper joint 311. The first ventilation groove and the second ventilation groove are respectively communicated with the corrugated expansion pipe 310. When the corrugated expansion pipe 310 is not compressed, the space inside it is relatively large, and air will evenly input air into the corrugated expansion pipe 310 and the air tank 302 through the air bag 211. When the corrugated expansion pipe 310 is compressed, the space inside the corrugated expansion pipe 310 decreases, the volume of the gas shrinks, resulting in an increase in gas pressure. The pressure of the internal gas rises, and the air bag 211 will output more air flow to the air tank 302 through the air inlet pipe 304 to balance the pressure. The air flow of the air bag 211 will increase the air pressure in the air tank 302. When the air pressure change in the air tank 302 exceeds the set threshold (±5%), the controller triggers the alarm 312. The threshold is preset through experiments according to the ground hardness. It should be noted that the diameter of the connecting pipe 314 is small, and when the corrugated expansion pipe 310 is compressed, although air will flow in the connecting pipe 314, the discharged amount is small, resulting in an increase in air pressure inside the corrugated expansion pipe 310, causing an air pressure difference between the corrugated expansion pipe 310 and the air tank 302. Thus, the air in the corrugated expansion pipe 310 will flow back into the air tank 302, and at the same time, more air in the air bag 211 will enter the air tank 302, increasing the air pressure in the air tank 302 to balance the air pressure difference between the corrugated expansion pipe 310 and the air tank 302. The increase in the internal air pressure of the air tank 302 further controls the alarm 312 to give an alarm through the pressure detection element. A sliding sleeve 313 is slidably sleeved on the outer wall of the support 102 above the rotating cushion plate 305. A screw is threadedly installed on the outer wall of the sliding sleeve 313. The sliding sleeve 313 is fixedly connected to the upper joint 311. An alarm 312 is fixedly installed on the upper end surface of the upper joint 311. The alarm 312 is an existing buzzer alarm device, and its working principle is to drive the built-in oscillator through current or voltage changes, thereby generating sound. The alarm 312 is electrically connected to the controller,One side of the upper joint 311 is fixedly connected to the air outlet pipe 206 at a position corresponding to the second ventilation groove. The lower end surface of the support frame 208 is fixedly installed with a bottom support frame 301. The lower end surface of the bottom support frame 301 is fixedly installed with a gas collecting pipe 303. The upper end surface of the gas collecting pipe 303 is communicated with a ventilation pipe, and the ventilation pipe penetrates through the bottom support frame 301 and is communicated with each gas tank 302. The inner diameter of the ventilation pipe is smaller than the inner diameter of the air inlet pipe 304. A plurality of connecting pipes 314 are circumferentially arrayed and communicated with the outer wall of the gas collecting pipe 303. The inner diameter of the connecting pipe 314 is smaller than the inner diameter of the air outlet pipe 206. The connecting pipe 314 is fixedly connected to the rotating backing plate 305. The outer wall of the gas collecting pipe 303 is communicated with an external connecting pipe 315. The lower end surface of one of the support frames 208 is fixedly installed with a flow divider 316. The flow divider 316 is communicated with the external connecting pipe 315. A plurality of spray pipes 317 are communicated with one side of the flow divider 316 close to the rotary drive member 202.,

[0022] Referring to Figure 8 It further includes a dust cleaning assembly 4. The dust cleaning assembly 4 includes a dust-proof protective cover 401 fixedly installed on one side of the surveying member 1. A circular hole is opened in the dust-proof protective cover 401. A clamping groove 406 is fixedly installed in the circular hole. A protective glass is embedded in the clamping groove 406. A plurality of air inlet grooves 405 are opened above the circular hole in the dust-proof protective cover 401. A flow dividing pipe 403 is arranged above the dust-proof protective cover 401. The flow dividing pipe 403 has three communication ports and an input port. A second rotating head 404 is rotatably installed on the outer wall of the output port. The second rotating head 404 is communicated with the external connecting pipe 315 through a hose. One of the communication ports is communicated with an air inlet cover 402. The air inlet cover 402 is fixedly connected to the dust-proof protective cover 401. The other two communication ports are communicated with an air inlet box 411. The air inlet box 411 is fixedly connected to both sides of the dust-proof protective cover 401; An integration groove 407 is opened below the circular hole inside the dust-proof protective cover 401. A conical collection box 408 is fixedly installed in the integration groove 407. An exhaust groove 409 is opened on the inner wall of the integration groove 407 below the conical collection box 408. A dust discharge port 410 is fixedly installed in the exhaust groove 409. The dust discharge port 410 is communicated with the air inlet box 411. A dust discharge pipe is communicated with the lower end surface of the air inlet box 411. The lower end of the dust discharge pipe is communicated with a dust collection box 412. An air outlet is opened on the lower end surface of the dust collection box 412. A filter cotton is fixedly installed in the dust collection box 412. The filter cotton arranged in the dust collection box 412 can be replaced by removing the dust collection box 412 and taking out the filter cotton from the air outlet. Moreover, the above-mentioned air outlet pipe 206 and the external connecting pipe 315 are both made of rubber material, having certain elasticity and softness and being able to bend arbitrarily.,

[0023] The working principle of the present invention is as follows: 1. Fix the surveying member 1: By rotating each support 102, insert each support 102 into the soil (for attachment Figure 1For example, there are three brackets 102 set. Inserting the three brackets 102 into the soil can support the surveying and mapping piece 1 and keep it balanced. By turning the screw, the sliding sleeve 313 can freely slide on the outer wall of the bracket 102. When the bracket 102 is inserted into the soil, rotate the rotating cushion plate 305 so that its lower end surface contacts the soil surface. The sliding sleeve 313 slides on the outer wall of the bracket 102 and stretches the corrugated expansion pipe 310 through the upper joint 311, so that the corrugated expansion pipe 310 extends between the rotating cushion plate 305 and the upper joint 311. During the process of the rotating cushion plate 305 contacting the soil surface, the rotating cushion plate 305 will wind up the coil spring 308, so that the rotating cushion plate 305 presses against the soil surface. In this way, when each bracket 102 is inserted into the soil, the set rotating cushion plate 305 will press down on the soil on the outer wall of the bracket 102, so that the lower end surface of the surveying and mapping piece 1 is kept horizontally perpendicular to the soil surface; Through the set telescopic connecting rod 103, the connecting disk 212 can freely lift and lower along the telescopic connecting rod 103 below the surveying and mapping piece 1. By turning on the rotary drive 202 to drive the shaft rod 203 to rotate, the rotating shaft rod 203 will drive the lifting disk 204 to reciprocate up and down on the inner wall of the air injection barrel 201. During the process of the lifting disk 204 rising in the air injection barrel 201, it will squeeze the air in the air injection barrel 201. The squeezed air will enter the airbag 211 through the one-way pressure relief valve 207 and the air outlet pipe 206, so that the airbag 211 expands. During the process of the lifting disk 204 descending in the air injection barrel 201, it will draw in the external air through the one-way valve 205 into the air injection barrel 201. In this way, the external air is reciprocally drawn in and the external air is squeezed and discharged into the airbag 211. The air entering the airbag 211 will be transported to the corrugated expansion pipe 310 and the air tank 302 respectively through the air outlet pipe 206 and the air inlet pipe 304; It should be noted that the set second ventilation groove can effectively allow air to enter the corrugated expansion pipe 310. When the air enters the corrugated expansion pipe 310, it will flow into the connecting pipe 314 through the first ventilation groove, and then flow into the collecting pipe 303 through the connecting pipe 314. The inner diameter of the connecting pipe 314 is smaller than the inner diameter of the air outlet pipe 206. Therefore, the air transported into the corrugated expansion pipe 310 will form a gas volume difference during the process of being discharged through the connecting pipe 314, and the air in the corrugated expansion pipe 310 will be in a high-pressure state through the gas volume difference; The air entering the air tank 302 through the air inlet pipe 304 will be transported into the collecting pipe 303 through the ventilation pipe. The inner diameter of the ventilation pipe is smaller than the inner diameter of the air inlet pipe 304. When the air entering the air tank 302 is discharged into the collecting pipe 303 through the ventilation pipe, a gas volume difference will be formed, and the air in the air tank 302 will be in a high-pressure state through the gas volume difference; Generally speaking, when the air entering the corrugated expansion pipe 310 and the air tank 302 is discharged slowly due to the difference in air volume, the air continuously delivered from the air injection barrel 201 into the airbag 211 will also continuously increase, enabling the air in the airbag 211 to accumulate to a certain flow rate, and continuously delivering air into the corrugated expansion pipe 310 and the air tank 302 evenly through the air outlet pipe 206 and the air inlet pipe 304. This ensures that the air delivered into the corrugated expansion pipe 310 and the air tank 302 can maintain a certain air pressure through the air volume difference during discharge. The pressure detection element installed in the air tank 302 can detect the air pressure value in the air tank 302, and synchronously generate corresponding electrical signals when the air pressure in the air tank 302 increases or decreases. When the pressure detection element detects the air pressure in the air tank 302, it needs to detect that the air pressure in the air tank 302 exceeds the set specified value before controlling the alarm 312 to beep through the controller; 2. Detection of deviation: When the soil where one of the brackets 102 is inserted becomes loose, the bracket 102 will sink. Refer to Figure 9 (Points B, C, and D are the grounding positions of the bracket 102, used to indicate the deflection state when the three-point support fails). Assume that the positions where each bracket 102 is inserted into the soil are point B, point C, and point D respectively. When the soil at point D becomes loose, the bracket 102 at point D will sink, causing the surveying component 1 to deflect away from points B and C. The lower end surface of the surveying component 1 will no longer be horizontally perpendicular to the soil surface. When the bracket 102 at point D sinks into the soil, the rotating cushion plate 305 will slide and rise in the chute 318 through the chuck 306, driving the fixed seat 309 to rise and continuously compress the corrugated expansion pipe 310, reducing the space inside the corrugated expansion pipe 310. The air in the airbag 211 will then be delivered into the air tank 302 through the air inlet pipe 304, increasing the air pressure in the air tank 302. The installed pressure detection element will detect the increase in air pressure in the air tank 302 and generate an electrical signal corresponding to the air pressure. The controller will then control the voltage input to the alarm 312 installed at the sunken position through the generated electrical signal, causing the alarm 312 to beep. Personnel can then judge which point has sunk by observing the alarm of the alarm 312 and find a hard soil area to re-fix, so as to avoid the surveying component 1 being deflected due to the sinking of one of the brackets 102; Similarly, when the supports 102 at points B, C, and D sink synchronously, the rotating backing plate 305 will also slide upward on the outer wall of the support 102 to compress the corrugated expansion pipe 310, reducing the space inside the corrugated expansion pipe 310. The air in the airbag 211 will be transported through the air inlet pipe 304 to the air tank 302, increasing the air pressure in the air tank 302. Then, it is detected by the pressure detection element and an alarm is issued through the alarm 312, enabling the determination that the soil into which the support 102 is inserted is loose, resulting in the subsidence of the surveying component 1. 3. Dust cleaning: The air transported by the connecting pipe 314 and the ventilation pipe into the collecting pipe 303 will be transported to the diverter 316 through the external connecting pipe 315 and then sprayed out by the spray pipe 317 to cool the rotary drive member 202, preventing the rotary drive member 202 from overheating due to long-term operation and avoiding the aging of insulating materials caused by excessive temperature. Part of the air entering the external connecting pipe 315 will be transported into the shunt pipe 403 through the hose. The air entering the shunt pipe 403 will be transported to the air inlet hood 402 and the air inlet box 411 respectively. The air entering the air inlet hood 402 will be sprayed onto the protective glass through the air inlet groove 405, causing the dust attached to the protective glass to flow into the integrated groove 407 (the dust attached to the protective glass may be static electricity or dust left by personnel touching the protective glass), and will be concentrated at the inner bottom end of the integrated groove 407 through the conical collection box 408. The air entering the air inlet box 411 will enter the dust collection box 412 through the dust discharge pipe. The dust that enters the inner bottom end of the integrated groove 407 and accumulates will enter the air inlet box 411 through the dust discharge port 410. As the air circulates in the air inlet box 411, it will be discharged into the dust collection box 412 together. The dust will be filtered by the filter cotton (the filter cotton is made of polyester fiber), and the filtered air can be discharged through the air outlet. This can effectively prevent dust during exploration and excessive dust attached to the lens of the surveying component 1 from affecting the exploration effect. At the same time, collecting dust can effectively prevent excessive dust from floating in the air and being inhaled by personnel, affecting their health. After the exploration technology, by sliding the support 102 into the chute and pushing the arc-shaped lever to slide within the arc-shaped slide seat, the support 102 can be clamped in the chute to prevent the support 102 from swinging, facilitating the portability of subsequent transfer.
