Description

Technical Field

[0001] The invention relates to the technical field of engineering surveying and mapping equipment, in particular to an instrument positioning structure for engineering surveying and mapping. Background Art

[0002] Surveying and mapping refers to the measurement, collection and drawing of the shape, size, spatial position and attributes of natural geographical elements or artificial facilities on the surface. With the continuous development of society, some surveying and mapping instruments have begun to appear. Surveying and mapping instruments, in simple terms, are instruments and devices designed and manufactured for surveying and mapping operations for data collection, processing, and output. Conventional measuring equipment mostly uses laser measuring devices or tape measures. Tape measures are divided into soft tape measures and steel tape measures. Due to the dusty engineering environment, laser measuring equipment will cause inaccurate measurements due to the cover of dust, and steel rulers are limited by their own material, and the length that can be measured is difficult to meet engineering needs.

[0003] Therefore, when laser measuring equipment cannot be used, a tape measure will be used instead of a measuring tool for detection. During this process, the wind flow inside the project will cause a large bend in the center of the tape measure, resulting in a large deviation in the measurement data. To address the above issues, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an engineering surveying and mapping instrument positioning structure, comprising a shell, a collecting wheel 1 is rotatably connected to the inner wall of the shell, a rotating disk is fixedly connected to the side wall of the collecting wheel 1, a measuring instrument 1 is fixedly connected to the top of the shell, and two rolling wheels are rotatably connected to the inner wall of the measuring instrument 1; The transmission mechanism includes an expansion pipe, a transmission pipe for penetrating and connecting the expansion pipe, and a gas outlet one-way valve, and an inflatable component for filling the expansion pipe; The inner wall of the collecting wheel 1 is fixedly connected to the outer wall of the expansion tube, the end of the expansion tube away from the collecting wheel 1 is fixedly connected to the outer wall of the transmission tube, and the end of the transmission tube away from the expansion tube is connected to the side wall of the gas outlet one-way valve; The power mechanism includes an air pressure box which is connected through the side wall of the air outlet one-way valve, a mounting plate is fixedly connected to the side wall of the air pressure box, a rotating column is rotatably connected to the inner wall of the mounting plate, an arc panel is fixedly connected to the side wall of the rotating column, and a collecting wheel 2 is fixedly connected to the end of the rotating column away from the arc panel, a steel wire is sleeved on the inner wall of the collecting wheel 2, an insertion rod is fixedly connected to the bottom of the mounting plate, and a correction assembly is fixedly connected to the side wall of the mounting plate. The expansion tube drives the rolling wheel to rotate, and a measuring instrument detects the rotating rolling wheel to complete the measurement. In this process, the rolling wheels clamped by each other will clamp one end of the expansion tube, so that when the expansion tube is inflated, the rolling wheel can prevent excess gas from entering the inside of the outer shell, causing the expansion tube inside the outer shell to expand, making it difficult to pull out the expansion tube inside the outer shell.

[0005] Preferably, the inflation component includes a sliding rod slidably connected to the top of the air pressure box, the top of the sliding rod is rotatably connected to a roller, the end of the sliding rod away from the roller is fixedly connected to a piston plate 1, the top of the piston plate 1 is fixedly connected to a spring 1, the bottom of the piston plate 1 is provided with an inclined groove, and a stabilizing component is fixedly connected to the inner wall of the air pressure box. Before use, the insertion rod is inserted into the soil at the desired position, and then the staff grasps the shell in their hands and moves it to the positioning position. As the distance between the shell and the insertion rod increases, the expansion tube will be pulled to extend outward, and the outwardly extended expansion tube will force the two rolling wheels to rotate, and at this time the measuring instrument detects the rolling wheels. The number of rotations is used to measure the distance between the outer shell and the insertion rod; as the distance between the outer shell and the insertion rod increases, the steel wire also forces the collecting wheel 2 to rotate, and the rotating collecting wheel 2 drives the arc panel to rotate synchronously through the rotating column. When the rotating arc panel rotates downward, it contacts the outer wall of the roller, forcing the roller to drive the piston plate 1 to slide downward along the inner wall of the air pressure box through the sliding rod, so that the gas at the bottom of the piston plate 1 is transmitted to the inside of the transmission pipe through the outlet one-way valve, and then transmitted from the inside of the transmission pipe to the inside of the expansion pipe, so that the expansion pipe expands, and the expanded expansion pipe will increase its own supporting force, reduce the expansion pipe under the influence of wind flow, and appear excessive bending arc, which affects the measurement data.

[0006] Preferably, the inflation component also includes a fixed frame fixedly connected to the bottom of the piston plate 1, a blocking rod is slidably connected to the inner wall of the fixed frame, a spring 2 is fixedly connected to the outer wall of the blocking rod, an air inlet check valve is through-connected to the side wall of the air pressure box, and a blocking component is fixedly connected to the outer wall of the transmission pipe. The characteristic of the inflation component forcing the expansion tube to expand is utilized, and an air inlet check valve and a blocking rod are arranged inside the equipment. When the piston plate 1 slides downward, the air pressure box will draw external air into the top of the piston plate 1 through the air inlet check valve. After the arc panel is away from the outer wall of the roller, the spring 1 releases mechanical power, so that the piston plate 1 slides upward along the inner wall of the air pressure box. At this time, the gas at the top of the piston plate 1 will reach the bottom of the piston plate 1 through the gap between the blocking rod and the inclined groove. Subsequently, when the arc panel contacts the outer wall of the roller again, the piston plate 1 and the blocking rod will force the gas at the bottom of the piston plate 1 to be discharged outward through the air outlet check valve. Through the application of the above-mentioned components, it is ensured that as the length of the expansion tube increases, the total amount of gas that the air pressure box can provide also increases synchronously.

[0007] Preferably, the stabilizing assembly includes a rotating rod rotatably connected to the inner wall of the air pressure box, an arc spring is fixedly connected to the side wall of the rotating rod, a gear rod is slidably connected to the inner wall of the insertion rod, a right-angle groove is opened on the side wall of the rotating rod, a rotating contact plate is rotatably connected to the inner wall of the right-angle groove, an L-shaped arc sliding rod is slidably connected to the inner wall of the side through hole of the air pressure box, and a spring four is fixedly connected to the side wall of the L-shaped arc sliding rod, utilizing the characteristic of the above-mentioned piston plate one sliding up and down. A stabilizing component is provided inside the equipment. When the expansion tube moves downward, the bottom of the piston plate 1 will contact one end of the rotating rod, forcing the rotating rod to be centered at the connection point and forcing the other end to tilt upward. The tilted rotating rod drives the gear rod to slide upward along the inner wall of the air pressure box through the rotating contact plate. The upward gear rod drives the piston plate 2 to move upward along the liquid storage tank 1 through the moving rod, so that the liquid on the top of the piston plate 2 is transmitted to the inside of the liquid storage tank 2 through the transmission groove. As the solution inside the liquid storage tank 2 increases, the hydraulic telescopic rod will be forced to extend. The extended hydraulic telescopic rod will increase the contact area between the insertion rod and the soil. Through the application of the above components, it is avoided that as the length of the expansion tube increases, the pulling force on the insertion rod will also increase synchronously, causing the insertion rod to tilt and affecting the measurement accuracy of the equipment.

[0008] Preferably, the stabilizing assembly also includes a liquid storage tank 1 provided on the inner wall of the insertion rod, a moving rod is fixedly connected to the bottom of the gear rod, a piston plate 2 is fixedly connected to the end of the moving rod away from the gear rod, an outer wall of the piston plate 2 is slidably connected to the inner wall of the liquid storage tank 1, a transmission groove is provided on the inner wall of the insertion rod, a liquid storage tank 2 is provided at the end of the transmission groove away from the liquid storage tank 1, and a hydraulic telescopic rod is connected through the side wall of the insertion rod.

[0009] Preferably, the blocking assembly includes an exhaust port opened at the side wall of the transmission pipe, a fixing ring is fixedly connected to the outer wall of the transmission pipe, a spring five is slidably connected to the outer wall of the transmission pipe, and a sliding blocking ring is fixedly connected to the side wall of the spring five. After the equipment completes the measurement, the staff can push the spring five to make the spring five slide outward along the outer wall of the transmission pipe. Then, when the expansion tube is recovered by the rotating disk, the two rolling wheels will squeeze the expansion tube, so that the gas inside the expansion tube is ejected outward through the exhaust port, thereby avoiding the phenomenon that air remains inside the expansion tube and the expansion tube is difficult to be recovered into the inner part of the outer shell.

[0010] Preferably, the correction assembly includes an L-shaped rod fixedly connected to the side wall of the mounting plate, one end of the steel wire away from the second collecting wheel is fixedly connected to a connecting block, and the side wall of the connecting block is fixedly connected to the outer wall of the shell.

[0011] Preferably, the inner wall of the hydraulic telescopic rod is through-connected with the inner wall of the liquid storage tank 2, the end of the arc spring away from the rotating rod is fixedly connected to the inner wall of the air pressure box, and the end of the spring 1 away from the piston plate 1 is fixedly connected to the inner wall of the air pressure box. When the gear rod moves upward, the inner wall of the upwardly moved gear rod contacts the arc surface of the L-shaped arc sliding rod, forcing the L-shaped arc sliding rod to slide along the inner wall of the air pressure box, and when the rotating rod is reset by the arc spring, when the bottom of the rotating contact plate contacts the inner wall of the gear rod, the rotating contact plate will tilt upward, and the rotating contact plate will not move the gear rod at this time; after the equipment completes the measurement, the staff can press the roller and then rotate the arc panel to recover the steel wire.

[0012] The present invention has the following beneficial effects: (1) The present invention aims to solve the problem that a tape measure is prone to bending during measurement. An inflatable assembly and a power mechanism are arranged inside the device. Before use, the insertion rod is inserted into the soil at the desired position. As the distance between the outer shell and the insertion rod increases, the expansion tube is pulled and extends outward. As the distance between the outer shell and the insertion rod increases, the steel wire also forces the collecting wheel 2 to rotate, forcing the roller to drive the piston plate 1 to slide downward along the inner wall of the air pressure box through the sliding rod, so that the gas at the bottom of the piston plate 1 is transmitted to the inside of the expansion tube through the air outlet one-way valve, causing the expansion tube to expand. The expanded expansion tube will increase its own supporting force, thereby reducing the expansion tube from being excessively bent under the influence of wind flow, thereby affecting the measurement data.

[0013] (2) The present invention utilizes the characteristics of the inflation assembly to force the expansion tube to expand. An air inlet check valve and a blocking rod are provided inside the device. After the arc plate is away from the outer wall of the roller, the spring 1 releases the mechanical power, causing the piston plate 1 to slide upward along the inner wall of the air pressure box. Subsequently, when the arc plate contacts the outer wall of the roller again, the piston plate 1 and the blocking rod will force the gas at the bottom of the piston plate 1 to be discharged outward through the air outlet check valve. Through the application of the above-mentioned components, it is ensured that as the length of the expansion tube increases, the total amount of gas that the air pressure box can provide also increases synchronously.

[0014] (3) The present invention utilizes the characteristic of the piston plate 1 sliding up and down, and a stabilizing component is arranged inside the device. When the expansion tube moves downward, the bottom of the piston plate 1 will contact one end of the rotating rod, forcing the rotating rod to be centered on the connection point and the other end to bend upward. The upward-tilted rotating rod drives the gear rod to slide upward along the inner wall of the air pressure box through the rotating contact plate, so that the solution inside the liquid storage tank 2 increases, forcing the hydraulic telescopic rod to extend. Through the application of the above-mentioned component, it is avoided that the pulling force on the insertion rod increases synchronously with the increase of the length of the expansion tube, causing the insertion rod to tilt and affecting the measurement accuracy of the equipment.

[0015] (4) In the present invention, the expansion tube drives the rolling wheel to rotate, and the measuring instrument detects the rotating rolling wheel to complete the measurement. During this process, the rolling wheels clamped together will clamp one end of the expansion tube, so that when the expansion tube is inflated, the rolling wheel can prevent excess gas from entering the interior of the outer shell, causing the expansion tube inside the outer shell to expand, making it difficult to pull out the expansion tube inside the outer shell.

[0016] (5) After the equipment completes the measurement, the staff can push the spring five to make it slide outward along the outer wall of the transmission pipe. Then, when the expansion tube is recovered by the rotating disk, the two rolling wheels will squeeze the expansion tube, so that the gas inside the expansion tube will be ejected outward through the exhaust port, thereby avoiding the phenomenon that air remains inside the expansion tube and the expansion tube is difficult to be recovered into the shell.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] For example, see Figure 1 - Figure 4 The present invention is an instrument positioning structure for engineering surveying and mapping, comprising a housing 1, a collecting wheel 11 is rotatably connected to the inner wall of the housing 1, a rotating disk 13 is fixedly connected to the side wall of the collecting wheel 11, a measuring instrument 14 is fixedly connected to the top of the housing 1, and two rolling wheels 15 are rotatably connected to the inner wall of the measuring instrument 14; The transmission mechanism 2 includes an expansion pipe 23, a transmission pipe 21 connected to the expansion pipe 23, and a gas outlet check valve 22, and an inflatable component 3 for filling the expansion pipe 23; The inner wall of the collecting wheel 11 is fixedly connected to the outer wall of the expansion pipe 23, the end of the expansion pipe 23 away from the collecting wheel 11 is fixedly connected to the outer wall of the transmission pipe 21, and the end of the transmission pipe 21 away from the expansion pipe 23 is connected to the side wall of the gas outlet check valve 22; The power mechanism 4 includes an air pressure box 31 which is connected to the side wall of the air outlet check valve 22. A mounting plate 41 is fixedly connected to the side wall of the air pressure box 31. A rotating column 42 is rotatably connected to the inner wall of the mounting plate 41. An arc panel 43 is fixedly connected to the side wall of the rotating column 42. A collecting wheel 2 44 is fixedly connected to one end of the rotating column 42 away from the arc panel 43. A steel wire 46 is sleeved on the inner wall of the collecting wheel 2 44. An insertion rod 45 is fixedly connected to the bottom of the mounting plate 41. A correction assembly 7 is fixedly connected to the side wall of the mounting plate 41. When the expansion tube 23 drives the rolling wheel 15 to rotate, the measuring instrument 14 detects the rotating rolling wheel 15 to complete the measurement. During this process, the rolling wheels 15 clamped against each other will clamp one end of the expansion tube 23, so that when the expansion tube 23 is inflated, the rolling wheel 15 can prevent excess gas from entering the interior of the outer shell 1, causing the expansion tube 23 inside the outer shell 1 to expand, making it difficult to pull out the expansion tube 23 inside the outer shell 1.

[0022] For example 2, please refer to Figure 5 - Figure 8 The present invention is a positioning structure for an engineering surveying instrument. On the basis of the first embodiment, the inflatable component 3 includes a sliding rod 32 slidably connected to the top of the air pressure box 31, the top of the sliding rod 32 is rotatably connected to the roller 33, the end of the sliding rod 32 away from the roller 33 is fixedly connected to a piston plate 34, the top of the piston plate 34 is fixedly connected to a spring 35, the bottom of the piston plate 34 is provided with an inclined groove 36, and the inner wall of the air pressure box 31 is fixedly connected to a stabilizing component 5. Before use, the insertion rod 45 is inserted into the soil at the desired position, and then the staff grasps the shell 1 in their hands and moves it to the positioning position. As the distance between the shell 1 and the insertion rod 45 increases, the expansion tube 23 is pulled to extend outward, and the outwardly extended expansion tube 23 will force the two rolling wheels 15 to rotate, and at this time the measuring instrument 1 14 measures the distance between the outer shell 1 and the insertion rod 45 by detecting the number of rotations of the rolling wheel 15; and as the distance between the outer shell 1 and the insertion rod 45 increases, the steel wire 46 also forces the collecting wheel 2 44 to rotate, and the rotating collecting wheel 2 44 drives the arc panel 43 to rotate synchronously through the rotating column 42. When the rotating arc panel 43 rotates downward, it contacts the outer wall of the roller 33, forcing the roller 33 to drive the piston plate 1 34 to slide downward along the inner wall of the air pressure box 31 through the sliding rod 32, so that the gas at the bottom of the piston plate 1 34 is transmitted to the inside of the transmission pipe 21 through the exhaust one-way valve 22, and then transmitted from the inside of the transmission pipe 21 to the inside of the expansion pipe 23, so that the expansion pipe 23 expands, and the expanded expansion pipe 23 will increase its own supporting force, reduce the expansion pipe 23 under the influence of wind flow, and appear too large bending arc, affecting the measurement data.

[0023] The inflation component 3 also includes a fixing frame 37 fixedly connected to the bottom of the piston plate 34, a blocking rod 38 is slidably connected to the inner wall of the fixing frame 37, a spring 39 is fixedly connected to the outer wall of the blocking rod 38, an air intake check valve 310 is connected through the side wall of the air pressure box 31, and a blocking component 6 is fixedly connected to the outer wall of the transmission pipe 21. By utilizing the characteristic of the inflation component 3 forcing the expansion pipe 23 to expand, an air intake check valve 310 and a blocking rod 38 are arranged inside the equipment. When the piston plate 34 slides downward, the air pressure box 31 will draw external air into the top of the piston plate 34 through the air intake check valve 310, and After the arc plate 43 moves away from the outer wall of the roller 33, the spring 35 releases the mechanical power, causing the piston plate 34 to slide upward along the inner wall of the air pressure box 31. At this time, the gas at the top of the piston plate 34 will reach the bottom of the piston plate 34 through the gap between the blocking rod 38 and the inclined groove 36. Subsequently, when the arc plate 43 contacts the outer wall of the roller 33 again, the piston plate 34 and the blocking rod 38 will force the gas at the bottom of the piston plate 34 to be discharged outward through the air outlet check valve 22. Through the application of the above-mentioned components, it is ensured that as the length of the expansion tube 23 increases, the total amount of gas that the air pressure box 31 can provide also increases synchronously.

[0024] The stabilizing assembly 5 includes a rotating rod 51 rotatably connected to the inner wall of the air pressure box 31, an arc spring 52 is fixedly connected to the side wall of the rotating rod 51, a gear rod 53 is slidably connected to the inner wall of the insertion rod 45, a right-angle groove 54 is opened on the side wall of the rotating rod 51, a rotating contact plate 55 is rotatably connected to the inner wall of the right-angle groove 54, an L-shaped arc surface slide rod 56 is slidably connected to the inner wall of the side through hole of the air pressure box 31, and a spring 457 is fixedly connected to the side wall of the L-shaped arc surface slide rod 56, and the above-mentioned piston plate 34 slides up and down. The stabilizing assembly 5 is arranged inside the device. When the expansion tube 23 moves downward, the bottom of the piston plate 34 will contact one end of the rotating rod 51, forcing the rotating rod 51 to be centered at the connection point and forcing the other end to tilt upward, presenting a state as shown in FIG. Figure 6 The upward rotating rod 51 drives the gear rod 53 to slide upward along the inner wall of the air pressure box 31 by rotating the contact plate 55. The upward gear rod 53 drives the piston plate 2 510 to move upward along the liquid storage tank 1 58 through the moving rod 59, so that the liquid on the top of the piston plate 2 510 is transmitted to the inside of the liquid storage tank 2 512 through the transmission groove 511. As the solution inside the liquid storage tank 2 512 increases, the hydraulic telescopic rod 513 will be forced to extend. The extended hydraulic telescopic rod 513 will increase the contact area between the insertion rod 45 and the soil. Figure 6As shown, due to the presence of an arc surface at the bottom of the L-shaped arc sliding rod 56, when the gear rod 53 moves up, the L-shaped arc sliding rod 56 will move to the right. At this time, the spring four 57 will extend and accumulate mechanical power. After the gear rod 53 moves up one gear, the spring four 57 will pull the L-shaped arc sliding rod 56 to insert into the internal gap of the gear rod 53 again, so as to avoid the gear rod 53 from moving downward and shrinking due to the large resistance of the bottom hydraulic telescopic rod 513 inserted into the soil after each upward movement due to the limitation of the bottom resistance, thereby affecting the efficiency of the hydraulic telescopic rod 513 inserted into the soil. Through the application of the above-mentioned components, it is avoided that as the length of the expansion tube 23 increases, the pulling force on the insertion rod 45 also increases synchronously, causing the insertion rod 45 to tilt and affecting the measurement accuracy of the equipment.

[0025] The stabilizing assembly 5 also includes a liquid reservoir 1 58 provided on the inner wall of the insertion rod 45, a moving rod 59 is fixedly connected to the bottom of the gear rod 53, a piston plate 2 510 is fixedly connected to the end of the moving rod 59 away from the gear rod 53, an outer wall of the piston plate 2 510 is slidably connected to the inner wall of the liquid reservoir 1 58, a transmission groove 511 is provided on the inner wall of the insertion rod 45, a liquid reservoir 2 512 is provided on the end of the transmission groove 511 away from the liquid reservoir 1 58, and a hydraulic telescopic rod 513 is connected through the side wall of the insertion rod 45. The blocking assembly 6 includes an exhaust port 61 opened at the side wall of the transmission pipe 21, a fixing ring 62 is fixedly connected to the outer wall of the transmission pipe 21, a spring 5 63 is slidably connected to the outer wall of the transmission pipe 21, and a sliding blocking ring 64 is fixedly connected to the side wall of the spring 5 63. After the device completes the measurement, the staff can push the spring 5 63 to make the spring 5 63 slide outward along the outer wall of the transmission pipe 21, presenting as shown in the figure. Figure 7 state, and then when the expansion tube 23 is recovered by the rotating disk 13, the two crushing wheels 15 will squeeze the expansion tube 23, so that the internal gas of the expansion tube 23 will be ejected outward through the exhaust port 61, thereby avoiding the phenomenon that the air inside the expansion tube 23 remains and the expansion tube 23 is difficult to be recovered into the shell 1.

[0026] The correction assembly 7 includes an L-shaped rod 72 fixedly connected to the side wall of the mounting plate 41 , and one end of the steel wire 46 away from the collecting wheel 2 44 is fixedly connected to a connecting block 71 , and the side wall of the connecting block 71 is fixedly connected to the outer wall of the housing 1 .

[0027] The inner wall of the hydraulic telescopic rod 513 is through-connected with the inner wall of the liquid storage tank 2 512, the end of the arc spring 52 away from the rotating rod 51 is fixedly connected to the inner wall of the air pressure box 31, and the end of the spring 1 35 away from the piston plate 1 34 is fixedly connected to the inner wall of the air pressure box 31. When the gear rod 53 moves upward, the inner wall of the upwardly moved gear rod 53 contacts the arc surface of the L-shaped arc surface slide rod 56, forcing the L-shaped arc surface slide rod 56 to slide along the inner wall of the air pressure box 31. When the rotating rod 51 is reset by the arc spring 52, the bottom of the rotating contact plate 55 contacts the inner wall of the gear rod 53, and the rotating contact plate 55 will tilt upward. At this time, the rotating contact plate 55 does not move the gear rod 53. After the equipment completes the measurement, the staff can press the roller 33 and then rotate the arc panel 43 to recover the steel wire 46.

[0028] A specific application of this embodiment is: before use, the insertion rod 45 is inserted into the soil at the desired position, and then the staff grasps the shell 1 in their hands and moves it to the positioning position. As the distance between the shell 1 and the insertion rod 45 increases, the expansion tube 23 is pulled to extend outward, and the expansion tube 23 extending outward will force the two rolling wheels 15 to rotate. At this time, the measuring instrument 14 measures the distance between the shell 1 and the insertion rod 45 by detecting the number of rotations of the rolling wheels 15; and as the distance between the shell 1 and the insertion rod 45 increases, the steel wire 46 also forces the collecting wheel 2 44 to rotate, and the rotating The collecting wheel 2 44 drives the arc panel 43 to rotate synchronously through the rotating column 42. When the rotating arc panel 43 rotates downward, it contacts the outer wall of the roller 33, forcing the roller 33 to drive the piston plate 1 34 to slide downward along the inner wall of the air pressure box 31 through the sliding rod 32, so that the gas at the bottom of the piston plate 1 34 is transmitted to the inside of the transmission pipe 21 through the gas outlet one-way valve 22, and then transmitted from the inside of the transmission pipe 21 to the inside of the expansion pipe 23, so that the expansion pipe 23 expands, and the expanded expansion pipe 23 will increase its own supporting force, thereby reducing the excessive bending arc of the expansion pipe 23 under the influence of wind flow, thereby affecting the measurement data.

[0029] In order to utilize the characteristic of the inflation component 3 to force the expansion tube 23 to expand, an air inlet check valve 310 and a blocking rod 38 are arranged inside the device. When the piston plate 34 slides downward, the air pressure box 31 will draw external air into the top of the piston plate 34 through the air inlet check valve 310. After the arc panel 43 is away from the outer wall of the roller 33, the spring 35 releases the mechanical power, so that the piston plate 34 slides upward along the inner wall of the air pressure box 31. At this time, the gas at the top of the piston plate 34 will reach the bottom of the piston plate 34 through the gap between the blocking rod 38 and the inclined groove 36. Subsequently, when the arc panel 43 contacts the outer wall of the roller 33 again, the piston plate 34 and the blocking rod 38 will force the gas at the bottom of the piston plate 34 to be discharged outward through the air outlet check valve 22. Through the application of the above-mentioned components, it is ensured that as the length of the expansion tube 23 increases, the total amount of gas that the air pressure box 31 can provide also increases synchronously.

[0030] By utilizing the characteristics of the piston plate 34 sliding up and down, a stabilizing assembly 5 is provided inside the device. When the expansion tube 23 moves downward, the bottom of the piston plate 34 will contact one end of the rotating rod 51, forcing the rotating rod 51 to tilt upward with the connection point as the center, presenting a Figure 6 state, and the upward rotating rod 51 drives the gear rod 53 to slide upward along the inner wall of the air pressure box 31 through the rotating contact plate 55, and the upward gear rod 53 drives the piston plate 2 510 to move upward along the liquid storage tank 1 58 through the moving rod 59, so that the liquid on the top of the piston plate 2 510 is transmitted to the inside of the liquid storage tank 2 512 through the transmission groove 511. As the solution inside the liquid storage tank 2 512 increases, the hydraulic telescopic rod 513 will be forced to extend, and the extended hydraulic telescopic rod 513 will increase the contact area between the insertion rod 45 and the soil. Through the application of the above components, it is avoided that as the length of the expansion tube 23 increases, the pulling force on the insertion rod 45 is also increased synchronously, causing the insertion rod 45 to tilt, affecting the measurement accuracy of the equipment.

[0031] When the expansion tube 23 drives the rolling wheel 15 to rotate, the measuring instrument 14 detects the rotating rolling wheel 15 to complete the measurement. In this process, the rolling wheels 15 clamped together will clamp one end of the expansion tube 23, so that when the expansion tube 23 is inflated, the rolling wheel 15 can prevent excess gas from entering the shell 1, causing the expansion tube 23 inside the shell 1 to expand, making it difficult to pull out the expansion tube 23 inside the shell 1; in addition, after the equipment completes the measurement, the staff can push the spring five 63 to make the spring five 63 slide outward along the outer wall of the transmission tube 21, presenting a Figure 7 state, and then when the expansion tube 23 is recovered by the rotating disk 13, the two crushing wheels 15 will squeeze the expansion tube 23, so that the internal gas of the expansion tube 23 will be ejected outward through the exhaust port 61, thereby avoiding the phenomenon that the air inside the expansion tube 23 remains and the expansion tube 23 is difficult to be recovered into the shell 1.

[0032] When the gear rod 53 moves upward, the inner wall of the upward gear rod 53 contacts the arc surface of the L-shaped arc slide rod 56, forcing the L-shaped arc slide rod 56 to slide along the inner wall of the air pressure box 31. When the rotating rod 51 is reset by the arc spring 52, the bottom of the rotating contact plate 55 contacts the inner wall of the gear rod 53, and the rotating contact plate 55 will tilt upward. At this time, the rotating contact plate 55 does not move the gear rod 53. After the equipment completes the measurement, the staff can press the roller 33 and then rotate the arc panel 43 to recover the steel wire 46.
