Technical Field

[0001] The invention relates to the technical field of geological surveying and mapping equipment, in particular to a surveying ruler for geological surveying and mapping and a use method thereof. Background Art

[0002] Geological surveying is the general term for all surveying and mapping work involved in geological investigation and mineral exploration and the preparation of their results maps. In the process of geological surveying, a surveying ruler is needed to measure the ground. The existing surveying rulers generally use tape measures, which are divided into leather tape measures and steel tape measures. Since the steel tape measure is made of metal and has a larger thickness, its total measuring length is generally smaller. Therefore, leather tape measures are generally used when conducting geological surveys.

[0003] Geological surveying and mapping are mostly field operations. When using a tape measure for measurement, the tape will be extended. In addition, due to the material of the tape, when the external wind flows through, the middle of the tape will be greatly offset, affecting the measurement accuracy of the tape. To address the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a surveying ruler for geological surveying, comprising a shell, a driving rod rotatably connected to the inner wall of the shell, a soft ruler fixedly wound around the outer wall of the driving rod, an expansion tube fixedly connected to the side wall of the soft ruler, and a turbine spring fixedly connected to the outer wall of the driving rod;

[0005] The positioning mechanism includes an air pressure box fixedly connected to the end of the soft ruler away from the driving rod, the top of the air pressure box is fixedly connected to a fixing frame, the end of the fixing frame away from the air pressure box is rotatably connected to a collecting wheel, a pulling line is fixedly wound around the inner wall of the collecting wheel, a turbine spring 2 is fixedly connected to the side wall of the collecting wheel, a ground insertion rod is fixedly connected to the bottom of the air pressure box, a control component is fixedly connected to the side wall of the fixing frame, and a blocking component is fixedly connected to the side wall of the fixing frame;

[0006] The air intake mechanism comprises a sliding bracket fixedly connected to the top of the fixed bracket, a sliding track is slidably connected to the inner wall of the sliding bracket, a roller is rotatably connected to the side wall of the collecting wheel, an air outlet is opened at the side wall of the air pressure box, an N-shaped rod is fixedly connected to the side wall of the sliding track, an air pressure cylinder is fixedly connected to the inner wall of the through hole of the air pressure box, a one-way air outlet valve is fixedly connected to the inner wall of the air pressure cylinder, a piston plate is slidably connected to the inner wall of the air pressure cylinder, an air outlet through hole is opened on the top of the piston plate, a sliding bracket is slidably connected to the inner wall of the air outlet through hole, and a blocking block is fixedly connected to the top of the sliding bracket. In order to solve the problem that the soft ruler will deviate when facing windflow, a positioning mechanism and an air intake mechanism are arranged inside the equipment. Before use, the ground insertion rod is inserted into the required position to ensure that the ground insertion rod is stable, and then the staff holds the shell away from the ground insertion rod. In this process, as the distance between the ground insertion rod and the shell increases, the soft ruler and the pulling line will be pulled outward and extended, and at the same time drive the collecting wheel and the driving rod to rotate. , and realize the basic measurement effect, and during the rotation of the collecting wheel, the collecting wheel drives the sliding track to move up and down along the inner wall of the sliding bracket through the roller, and when the sliding track moves up, the sliding track drives the blocking block to move up synchronously through the N-type rod, and the blocking block drives the piston plate to move upward through the sliding bracket. In this process, the gap between the air outlet hole and the sliding bracket will form an air inlet, so that the air at the top of the piston plate is transmitted to the bottom of the piston plate through the air inlet, and when the collecting wheel rotates downward, the N-type rod drives the blocking block to block the air outlet hole, so that the piston plate forms a sealing plate, which moves downward along the inner wall of the air pressure cylinder, forcing the air at the bottom of the piston plate to enter the interior of the air pressure box through the one-way air outlet valve, and the air inside the air pressure box enters the expansion tube through the air outlet, causing the expansion tube to expand, and the expanded expansion tube will provide a supporting force for the extended soft ruler. Through the application of the above components, the expansion tube provides a supporting force for the soft ruler, thereby reducing the error of the measurement data of the soft ruler under the influence of wind flow.

[0007] Preferably, the control assembly includes a roller rotatably connected to the side wall of the fixing frame, a gear is fixedly connected to the side wall of the roller, and a transmission belt is sleeved on the outer wall of the collecting wheel.

[0008] Preferably, the controlled component also includes a gear rod slidably connected to the inner wall of the fixed frame, a gear block is slidably connected to the inner wall of the gear rod, and a compression spring is fixedly connected to the top of the gear block.

[0009] Preferably, the control component also includes a blocking disk fixedly connected to the bottom of the gear rod, an exhaust port is opened at the bottom of the air pressure box, the other end of the compressed spring is fixedly connected to the inner wall of the gear rod, and the end of the transmission belt away from the collecting wheel is rotatably connected to the outer wall of the roller. Utilizing the characteristic that the collecting wheel rotates when pulled by the pulling line, a control component is arranged inside the equipment, and the collection wheel rotates through the transmission belt to drive the roller to rotate in the same direction, and the rotation of the roller drives the gear rod to slide downward along the inner wall of the fixed frame through the gear, and the gear rod drives the blocking disk to move downward and block the exhaust port, so that when the soft ruler and the pulling line extend outward, the blocking disk blocks the exhaust port, and the air pressure box forms a closed space, so that After the air enters the air pressure box through the one-way air outlet valve, it can enter the expansion tube through the air outlet. When the gear pushes the gear rod to move downward to the lowest point, the gear will contact the outer wall of the gear block, forcing the gear block to slide downward along the inner wall of the gear rod. In this process, the gear block forces the gear rod downward to generate pressure through the compressed spring, so that the blocking disk always blocks the exhaust port when the tape is extended outward. In addition, after completing the data measurement and recycling the tape, the turbine spring 2 will release mechanical power to force the collection wheel to rotate in the opposite direction. The collection wheel drives the gear to rotate in the opposite direction synchronously through the transmission belt. At this time, the gear will drive the blocking disk away from the exhaust port through the gear rod, forming a Figure 10 The high-pressure gas in the air pressure box and the expansion tube will be discharged outward through the exhaust port. Through the application of the above components, it is avoided that during recovery, there is residual air in the expansion tube, which affects the recovery efficiency of the expansion tube.

[0010] Preferably, the blocking assembly includes an L-shaped rod fixedly connected to the side wall of the fixing frame, a length detector 1 is fixedly connected to the top of the L-shaped rod, and a length detector 2 is fixedly connected to the side wall of the housing.

[0011] Preferably, the blocking component also includes a correction plate fixedly connected to the side wall of the shell, and a limiting frame is fixedly connected to the side wall of the correction plate. An extrusion wheel is rotatably connected to the inner wall of the limiting frame. Utilizing the characteristic that the above-mentioned soft ruler will contact the inner wall of the correction plate when pulled outward, an extrusion wheel is arranged inside the equipment. When the soft ruler is pulled outward, a plurality of extrusion wheels will squeeze the expansion tube, forcing the expansion tube to form a blockage state. Through the application of the above-mentioned components, when the air pressure box transmits high-pressure gas to the inside of the expansion tube, excess gas is affected by the extrusion wheel squeezing the expansion tube and cannot enter the inside of the shell, thereby preventing high-pressure gas from entering the inside of the shell through the expansion tube, forcing the expansion tube inside the shell to expand, and affecting the efficiency of pulling the soft ruler out; in addition, through the application of the extrusion wheel, when the subsequent turbine spring releases the pressure to collect the soft ruler and the expansion tube, the extrusion wheel will squeeze out excess air inside the expansion tube, thereby preventing air residue and affecting the collection efficiency.

[0012] Preferably, one end of the N-shaped rod away from the sliding track is fixedly connected to the top of the blocking block, one end of the expansion tube away from the driving rod is connected through the inner wall of the air outlet, the outer wall of the roller is slidably connected to the inner wall of the sliding track, one end of the turbine spring 2 away from the collecting wheel is fixedly connected to the side wall of the fixing frame, one end of the pulling wire away from the collecting wheel is fixedly connected to the outer wall of the shell, and one end of the turbine spring 1 away from the driving rod is fixedly connected to the inner wall of the shell. A length detector is provided inside the device by utilizing the characteristic that when the distance between the shell and the ground insertion rod is expanded, the length of the pulling wire and the soft ruler extending outward is equal. When the staff drives the shell to the specified position, the length detector one and the length detector two will record the length of the pull line and the tape measure extending outward. At this time, the two sets of data can be compared. If the length of the pull line is greater than the tape measure, the horizontal height of the shell will be lower than the air pressure box. When the length of the pull line is less than the tape measure, the horizontal height of the shell will be higher than the air pressure box. Through the application of the above components, it is ensured that when the equipment is in use, it is possible to clearly observe whether the air pressure box and the shell are in the same horizontal position, so as to avoid the height of the position affecting the measurement accuracy of the equipment.

[0013] A method for using a surveying ruler for geological surveying and mapping comprises the following steps:

[0014] S1: Determine the location;

[0015] S2: measure distance;

[0016] S3: Recycling equipment.

[0017] The present invention has the following beneficial effects:

[0018] (1) In order to solve the problem that the tape measure will deviate when facing wind, the present invention provides a positioning mechanism and an air intake mechanism inside the device. Before use, the ground rod is inserted into the required position. After ensuring that the ground rod is stable, the staff then holds the outer shell away from the ground rod. During this process, as the distance between the ground rod and the outer shell increases, the tape measure and the pulling line will be pulled outward and extend, while driving the collection wheel and the driving rod to rotate and achieve the basic measurement effect. During the rotation of the collection wheel, the collection wheel drives the sliding track to move up and down along the inner wall of the sliding bracket through the roller. When the sliding track moves up, the sliding track drives the blocking block to move up synchronously through the N-shaped rod, and the blocking block drives the piston plate through the sliding bracket. When the piston plate moves upward, during this process, the gap between the air outlet hole and the sliding frame will form an air inlet, so that the air on the top of the piston plate is transmitted to the bottom of the piston plate through the air inlet. When the collecting wheel rotates downward, the N-shaped rod drives the blocking block to block the air outlet hole, so that the piston plate forms a sealing plate. The sealing plate moves downward along the inner wall of the air pressure cylinder, forcing the air at the bottom of the piston plate to enter the air pressure box through the one-way air outlet valve, and the air inside the air pressure box enters the expansion tube through the air outlet, causing the expansion tube to expand. The expanded expansion tube will provide a supporting force for the extended soft ruler. Through the application of the above components, the expansion tube provides a supporting force for the soft ruler, thereby reducing the error of the measurement data of the soft ruler under the influence of wind flow.

[0019] (2) The present invention utilizes the characteristic that the above-mentioned flexible ruler will contact the inner wall of the correction plate when being pulled outward, and an extrusion wheel is arranged inside the equipment. When the flexible ruler is pulled outward, a plurality of extrusion wheels will squeeze the expansion tube, forcing the expansion tube to be blocked. Through the application of the above-mentioned components, when the air pressure box transmits high-pressure gas to the expansion tube, the excess gas is affected by the extrusion wheel squeezing the expansion tube and cannot enter the outer shell, thereby preventing the high-pressure gas from entering the outer shell through the expansion tube, forcing the expansion tube inside the outer shell to expand, and affecting the efficiency of pulling the flexible ruler outward. In addition, through the application of the extrusion wheel, when the subsequent turbine spring releases the pressure to collect the flexible ruler and the expansion tube, the extrusion wheel will squeeze out the excess air inside the expansion tube, thereby preventing air residue from affecting the collection efficiency.

[0020] (3) The present invention utilizes the characteristic that the collecting wheel rotates when pulled by the pulling line, and a control component is arranged inside the device. The collecting wheel rotates through the transmission belt to drive the roller to rotate in the same direction. The roller rotates through the gear to drive the gear rod to slide downward along the inner wall of the fixed frame. The gear rod drives the blocking disk to move downward and block the exhaust port, so that when the soft tape and the pulling line extend outward, the blocking disk blocks the exhaust port, and the air pressure box forms a closed space, so that after the air enters the air pressure box through the one-way air outlet valve, it can enter the expansion tube through the air outlet. Among them, when the gear pushes the gear rod to move downward to the lowest point, the gear will contact the outer wall of the gear block, forcing the gear block to slide downward along the inner wall of the gear rod. In this process, the gear block forces the gear rod downward to generate pressure through the compression spring, so that the blocking disk always blocks the exhaust port when the soft tape extends outward. In addition, when the data measurement is completed and the soft tape is recovered, the turbine spring 2 will release mechanical power to force the collecting wheel to rotate in the opposite direction. The collecting wheel drives the gear to rotate in the opposite direction synchronously through the transmission belt. At this time, the gear will drive the blocking disk away from the exhaust port through the gear rod, forming a closed space as shown in FIG. Figure 10 The high-pressure gas in the air pressure box and the expansion tube will be discharged outward through the exhaust port. Through the application of the above components, it is avoided that during recovery, there is residual air in the expansion tube, which affects the recovery efficiency of the expansion tube.

[0021] (4) The present invention utilizes the characteristic that when the distance between the above-mentioned shell and the ground rod increases, the length of the pull line and the tape measure extending outward are equal. A length detector 1 and a length detector 2 are arranged inside the device. When the staff drives the shell to the specified position, the length detector 1 and the length detector 2 will record the length of the pull line and the tape measure extending outward. At this time, by comparing the two sets of data, if the length of the pull line is greater than the tape measure, the horizontal height of the shell will be lower than the air pressure box, and when the length of the pull line is less than the tape measure, the horizontal height of the shell will be higher than the air pressure box. Through the application of the above-mentioned components, it is ensured that when the device is in use, it is possible to clearly observe whether the air pressure box and the shell are in the same horizontal position, so as to avoid the height of the position affecting the measurement accuracy of the device.

[0039] 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.

[0040] For example, see Figure 1 - Figure 8 The present invention is a surveying ruler for geological surveying, comprising a housing 1, a driving rod 11 is rotatably connected to the inner wall of the housing 1, a flexible ruler 12 is fixedly wound around the outer wall of the driving rod 11, an expansion tube 13 is fixedly connected to the side wall of the flexible ruler 12, and a turbine spring 14 is fixedly connected to the outer wall of the driving rod 11;

[0041] The positioning mechanism 2 includes an air pressure box 21 fixedly connected to the end of the tape measure 12 away from the driving rod 11, a fixing frame 22 is fixedly connected to the top of the air pressure box 21, a collecting wheel 23 is rotatably connected to the end of the fixing frame 22 away from the air pressure box 21, a pulling line 24 is fixedly wound around the inner wall of the collecting wheel 23, a turbine spring 25 is fixedly connected to the side wall of the collecting wheel 23, a ground insertion rod 26 is fixedly connected to the bottom of the air pressure box 21, a control component 4 is fixedly connected to the side wall of the fixing frame 22, and a blocking component 5 is fixedly connected to the side wall of the fixing frame 22;

[0042] The air intake mechanism 3 includes a sliding bracket 31 fixedly connected to the top of the fixed frame 22, a sliding track 32 is slidably connected to the inner wall of the sliding bracket 31, a roller 33 is rotatably connected to the side wall of the collecting wheel 23, an air outlet 34 is provided on the side wall of the air pressure box 21, an N-shaped rod 35 is fixedly connected to the side wall of the sliding track 32, an air pressure cylinder 36 is fixedly connected to the inner wall of the through hole of the air pressure box 21, a one-way air outlet valve 37 is fixedly connected to the inner wall of the air pressure cylinder 36, a piston plate 38 is slidably connected to the inner wall of the air pressure cylinder 36, and an air outlet through hole 39 is provided on the top of the piston plate 38. A sliding frame 310 is slidably connected to the inner wall of the through hole 39, and a blocking block 311 is fixedly connected to the top of the sliding frame 310. In order to solve the problem that the soft ruler 12 will deviate when facing wind flow, a positioning mechanism 2 and an air intake mechanism 3 are arranged inside the device. Before use, the ground insertion rod 26 is inserted into the required position to ensure that the ground insertion rod 26 is stable, and then the staff holds the shell 1 away from the ground insertion rod 26. In this process, as the distance between the ground insertion rod 26 and the shell 1 increases, the soft ruler 12 and the pulling line 24 will be pulled outward and extended, and at the same time drive the collection wheel 23 and the driving rod 11 to rotate. And realize the basic measurement effect, while in the process of the collection wheel 23 rotating, the collection wheel 23 drives the sliding track 32 to move up and down along the inner wall of the sliding bracket 31 through the roller 33, when the sliding track 32 moves up, the sliding track 32 drives the blocking block 311 to move up synchronously through the N-shaped rod 35, and the blocking block 311 drives the piston plate 38 to move upward through the sliding bracket 310. In this process, the gap between the air outlet hole 39 and the sliding bracket 310 will form an air inlet, so that the air at the top of the piston plate 38 is transmitted to the bottom of the piston plate 38 through the air inlet, and when the collection wheel 23 rotates downward, the N-shaped rod 3 The blocking block 311 is driven to block the air outlet hole 39, so that the piston plate 38 forms a sealing plate. The sealing plate moves downward along the inner wall of the air pressure cylinder 36, forcing the air at the bottom of the piston plate 38 to enter the air pressure box 21 through the one-way air outlet valve 37, and the air inside the air pressure box 21 enters the expansion tube 13 through the air outlet 34, so that the expansion tube 13 expands, and the expanded expansion tube 13 will provide a supporting force for the extended soft ruler 12. Through the application of the above components, the expansion tube 13 provides a supporting force for the soft ruler 12, thereby reducing the error of the measurement data of the soft ruler 12 under the influence of wind flow.

[0043] For example 2, please refer to Fig. 9 - Fig.14 The present invention is a surveying ruler for geological surveying. Based on the first embodiment, the control component 4 includes a roller 41 rotatably connected to the side wall of the fixed frame 22, a gear 42 is fixedly connected to the side wall of the roller 41, and a transmission belt 43 is sleeved on the outer wall of the collecting wheel 23.

[0044] The controlled component 4 further comprises a gear rod 44 slidably connected to the inner wall of the fixing frame 22 , a gear block 45 is slidably connected to the inner wall of the gear rod 44 , and a compression spring 46 is fixedly connected to the top of the gear block 45 .

[0045] The control assembly 4 also includes a blocking disk 48 fixedly connected to the bottom of the gear rod 44. An exhaust port 47 is provided at the bottom of the air pressure box 21. The other end of the compressed spring 46 is fixedly connected to the inner wall of the gear rod 44. The end of the conveyor belt 43 away from the collecting wheel 23 is rotatably connected to the outer wall of the roller 41. By utilizing the characteristic that the collecting wheel 23 rotates when pulled by the pulling line 24, a control assembly 4 is arranged inside the device. The collecting wheel 23 rotates through the conveyor belt 43 to drive the roller 41 to rotate in the same direction. The roller 41 rotates through the gear 42 to drive the gear rod 44 to slide downward along the inner wall of the fixed frame 22. The gear rod 44 drives the blocking disk 48 to move downward and block the exhaust port 47. When the soft ruler 12 and the pulling line 24 extend outward, the blocking disk 48 blocks the exhaust port 47. The air pressure box 21 forms a closed space, so that the air After the air enters the air pressure box 21 through the one-way air outlet valve 37, it can enter the expansion tube 13 through the air outlet 34. When the gear 42 pushes the gear rod 44 to move downward to the lowest point, the gear 42 will contact the outer wall of the tooth block 45, forcing the tooth block 45 to slide downward along the inner wall of the gear rod 44. In this process, the tooth block 45 forces the gear rod 44 to generate pressure downward through the compression spring 46, so that the blocking disk 48 always blocks the exhaust port 47 when the flexible tape 12 extends outward. In addition, when the data measurement is completed and the flexible tape 12 is recovered, the turbine spring 25 will release mechanical power, forcing the collection wheel 23 to rotate in the opposite direction. The collection wheel 23 drives the gear 42 to rotate in the opposite direction synchronously through the transmission belt 43. At this time, the gear 42 will drive the blocking disk 48 away from the exhaust port 47 through the gear rod 44, forming a Figure 10 The high-pressure gas in the air pressure box 21 and the expansion tube 13 will be discharged outward through the exhaust port 47. Through the application of the above components, it is avoided that during recovery, there is residual air in the expansion tube 13, which affects the recovery efficiency of the expansion tube 13.

[0046] The blocking assembly 5 includes an L-shaped rod 51 fixedly connected to the side wall of the fixing frame 22 , a length detector 1 52 is fixedly connected to the top of the L-shaped rod 51 , and a length detector 2 53 is fixedly connected to the side wall of the housing 1 .

[0047] The blocking assembly 5 also includes a correction plate 54 fixedly connected to the side wall of the housing 1, a limiting frame 55 fixedly connected to the side wall of the correction plate 54, and an extrusion wheel 56 rotatably connected to the inner wall of the limiting frame 55. When the soft ruler 12 is pulled outward, it will contact the inner wall of the correction plate 54. The extrusion wheel 56 is arranged inside the device. When the soft ruler 12 is pulled outward, multiple extrusion wheels 56 will squeeze the expansion tube 13, forcing the expansion tube 13 to form a blocking state. Through the application of the above-mentioned components, the air pressure box 21 is pushed toward the expansion tube 1 When the high-pressure gas is transmitted inside, the excess gas is affected by the squeezing wheel 56 squeezing the expansion tube 13 and cannot enter the inside of the housing 1, so as to prevent the high-pressure gas from entering the inside of the housing 1 through the expansion tube 13, forcing the expansion tube 13 inside the housing 1 to expand, thereby affecting the efficiency of pulling the flexible tape 12 outward; in addition, through the use of the squeezing wheel 56, when the turbine spring 14 is released to collect the pressure of the flexible tape 12 and the expansion tube 13, the squeezing wheel 56 will squeeze out the excess air inside the expansion tube 13, thereby preventing air from remaining and affecting the collection efficiency.

[0048] One end of the N-shaped rod 35 away from the sliding track 32 is fixedly connected to the top of the blocking block 311, one end of the expansion tube 13 away from the driving rod 11 is connected to the inner wall of the air outlet 34, the outer wall of the roller 33 is slidably connected to the inner wall of the sliding track 32, one end of the turbine spring 25 away from the collecting wheel 23 is fixedly connected to the side wall of the fixing frame 22, one end of the pulling wire 24 away from the collecting wheel 23 is fixedly connected to the outer wall of the shell 1, and one end of the turbine spring 14 away from the driving rod 11 is fixedly connected to the inner wall of the shell 1. When the distance between the above-mentioned shell 1 and the ground insertion rod 26 is expanded, the pulling wire 24 and the soft ruler 12 are extended outward by the same length, and a length is set inside the equipment. When the staff drives the shell 1 to the specified position, the length detector 1 52 and the length detector 2 53 will record the length of the pull line 24 and the tape measure 12 extending outward. At this time, by comparing the two sets of data, if the length of the pull line 24 is greater than the tape measure 12, the horizontal height of the shell 1 will be lower than the air pressure box 21, and when the length of the pull line 24 is less than the tape measure 12, the horizontal height of the shell 1 will be higher than the air pressure box 21. Through the application of the above components, it is ensured that when the equipment is in use, it is possible to clearly observe whether the air pressure box 21 and the shell 1 are in the same horizontal position, so as to avoid the height of the position affecting the measurement accuracy of the equipment.

[0049] The method of using the measuring ruler includes the following steps:

[0050] S1: Determine the location;

[0051] S2: measure distance;

[0052] S3: Recycling equipment.

[0053] A specific application of this embodiment is: before use, the ground rod 26 is inserted into the required position. After ensuring that the ground rod 26 is stable, the staff then holds the shell 1 away from the ground rod 26. During this process, as the distance between the ground rod 26 and the shell 1 increases, the tape measure 12 and the pulling line 24 will be pulled outward to extend, while driving the collection wheel 23 and the driving rod 11 to rotate, and achieve a basic measurement effect. During the rotation of the collection wheel 23, the collection wheel 23 drives the sliding track 32 to move up and down along the inner wall of the sliding bracket 31 through the roller 33. When the sliding track 32 moves up, the sliding track 32 drives the blocking block 311 to move up synchronously through the N-shaped rod 35. The blocking block 311 drives the piston plate 38 to move upward through the sliding bracket 310. During this process, the air outlet hole 3 9 and the sliding frame 310 will form an air inlet, so that the air on the top of the piston plate 38 is transmitted to the bottom of the piston plate 38 through the air inlet. When the collecting wheel 23 rotates downward, the N-shaped rod 35 drives the blocking block 311 to block the air outlet hole 39, so that the piston plate 38 forms a sealing plate, and the sealing plate moves downward along the inner wall of the air pressure cylinder 36, forcing the air at the bottom of the piston plate 38 to enter the air pressure box 21 through the one-way air outlet valve 37, and the air inside the air pressure box 21 enters the expansion tube 13 through the air outlet 34, so that the expansion tube 13 expands, and the expanded expansion tube 13 will provide a supporting force for the extended soft ruler 12. Through the application of the above-mentioned components, the expansion tube 13 provides a supporting force for the soft ruler 12, thereby reducing the error of the measurement data of the soft ruler 12 under the influence of wind flow.

[0054] Taking advantage of the fact that the flexible ruler 12 will contact the inner wall of the correction plate 54 when being pulled outward, a squeezing wheel 56 is arranged inside the device. When the flexible ruler 12 is pulled outward, a plurality of squeezing wheels 56 will squeeze the expansion tube 13, forcing the expansion tube 13 to form a blocked state. By using the above-mentioned components, when the air pressure box 21 transmits high-pressure gas to the expansion tube 13, the excess gas is affected by the squeezing wheel 56 squeezing the expansion tube 13 and cannot enter the shell 1, thereby preventing the high-pressure gas from entering the shell 1 through the expansion tube 13, forcing the outside to be blocked. The expansion tube 13 inside the shell 1 expands, affecting the efficiency of pulling the tape measure 12 outward; in addition, through the use of the extrusion wheel 56, when the subsequent turbine spring 14 releases the pressure to collect the tape measure 12 and the expansion tube 13, the extrusion wheel 56 will squeeze out the excess air inside the expansion tube 13 to avoid air residue and affect the collection efficiency. Utilizing the characteristic that the collection wheel 23 rotates when pulled by the pulling line 24, a control component 4 is arranged inside the device, and the collection wheel 23 rotates through the transmission belt 43 to drive the roller 41 to rotate in the same direction, and the roller The gear 41 rotates through the gear 42 to drive the gear rod 44 to slide downward along the inner wall of the fixing frame 22, and the gear rod 44 drives the blocking plate 48 to move downward and block the exhaust port 47, so that when the soft ruler 12 and the pulling line 24 extend outward, the blocking plate 48 blocks the exhaust port 47, and the air pressure box 21 forms a closed space, so that after the air enters the air pressure box 21 through the one-way air outlet valve 37, it can enter the expansion tube 13 through the air outlet 34. Among them, when the gear 42 pushes the gear rod 44 to move downward to the lowest point, the gear 42 will contact the outer wall of the tooth block 45, forcing the tooth block 45 slides downward along the inner wall of the gear rod 44. During this process, the gear block 45 forces the gear rod 44 to generate pressure downward through the compression spring 46, so that the blocking disk 48 always blocks the exhaust port 47 when the flexible tape 12 extends outward. In addition, when the data measurement is completed and the flexible tape 12 is recovered, the turbine spring 25 will release the mechanical power to force the collection wheel 23 to rotate in the opposite direction. The collection wheel 23 drives the gear 42 to rotate in the opposite direction synchronously through the transmission belt 43. At this time, the gear 42 will drive the blocking disk 48 away from the exhaust port 47 through the gear rod 44, forming a Figure 10 The high-pressure gas in the air pressure box 21 and the expansion tube 13 will be discharged outward through the exhaust port 47. Through the application of the above components, it is avoided that during recovery, there is residual air in the expansion tube 13, which affects the recovery efficiency of the expansion tube 13.

[0055] Taking advantage of the fact that when the distance between the shell 1 and the ground rod 26 is enlarged, the length of the pull line 24 and the tape measure 12 extending outward are equal, a length detector 1 52 and a length detector 2 53 are arranged inside the device. When the staff drives the shell 1 to the specified position, the length detector 1 52 and the length detector 2 53 will record the length of the pull line 24 and the tape measure 12 extending outward. At this time, by comparing the two sets of data, if the length of the pull line 24 is greater than the tape measure 12, the horizontal height of the shell 1 will be lower than the air pressure box 21, and when the length of the pull line 24 is less than the tape measure 12, the horizontal height of the shell 1 will be higher than the air pressure box 21. Through the application of the above components, it is ensured that when the equipment is in use, it is possible to clearly observe whether the air pressure box 21 and the shell 1 are in the same horizontal position, so as to avoid the height of the position affecting the measurement accuracy of the equipment.
