[0003] The patent with the patent announcement number CN204702313U relates to the technical fields of territorial space planning and hydrographic surveying. This patent discloses a geological radar antenna rail traction device for slope detection, including a track, a trolley, and a traction component. The track is fixed on the slope to be detected, and the radar antenna is arranged on the trolley. The traction device includes a roller, a bracket, and a traction rope. The bracket is fixedly arranged at the top of the slope, the roller is rotatably arranged on the bracket, the traction rope is wound around the roller, and the roller pulls the trolley to travel along the track through the traction rope. The trolley travels on the track, improving the driving environment, reducing resistance, enhancing the stability of vehicle operation, and reducing the wear of the slope on the antenna.

However, the current device has the following problems: unstable movement during measurement may lead to repetition or omission of the measurement route, and additional time is required for route correction and re-measurement. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a self-propelled slope track surveying device dedicated to territorial space hydrographic surveying, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A self-propelled slope track measuring device dedicated to national land space hydrological measurement, including a ramp and a tripod. The tripod is arranged above the ramp. A lifting mechanism is arranged on the surface of the tripod. A plumb line is arranged on the circumferential surface of the tripod. A slide rail is arranged on the surface of the ramp. A measuring device is also included. Among them, the measuring device includes a measuring vehicle, a sealed box, a hollow block, a mounting rod, a first spring, a clamping block, and a rotating frame. The measuring vehicle is arranged at the connecting end of the lifting mechanism. A clamping groove is opened at the wheel of the measuring vehicle. The sealed box is slidably installed on the inner wall of the measuring vehicle. One side of the hollow block is slidably installed on the inner wall of the slide rail. The mounting rod is slidably installed in the inner wall of the hollow block. The side of the mounting rod close to the clamping groove is set as an inclined surface. The first spring is arranged between the mounting rod and the hollow block. The first spring drives the mounting rod to reset. The clamping block is fixedly installed on the circumferential surface of the mounting rod. The rotating frame is rotatably installed on the outer wall of the hollow block. A measuring instrument is arranged inside the sealed box. A first torsion spring is arranged between the clamping block and the hollow block. The first torsion spring drives the clamping block to reset. After the tripod is placed at the horizontal position of the ramp 1 and installed, the plumb line is used to measure whether the tripod is installed stably. After installation is stable, the measuring vehicle is moved to contact the slide rail through the lifting mechanism; Among them, a clearance removing device for removing obstacles when the measuring instrument moves and a protection device for protecting the measuring instrument are arranged on the front side of the measuring vehicle.

[0007] According to the above technical solution, the measuring device further includes a servo motor and a threaded rod. The fixed end of the servo motor is fixedly installed on the surface of the slide rail. The threaded rod is fixedly installed at the output end of the servo motor. The other side of the hollow block is threadedly installed on the circumferential surface of the threaded rod. A docking groove is opened on the surface of the sealed box. The output end of the servo motor rotates to drive the threaded rod to rotate. The rotation of the threaded rod causes the hollow block to move downward. The movement of the hollow block drives the measuring vehicle to move. The movement of the measuring vehicle drives the sealed box to move, that is, drives the measuring instrument to move underwater. A water quality sensor and a depth sensor are arranged in the measuring instrument, which is convenient for measuring relevant hydrological parameters.

[0008] According to the above technical solution, the clearance removing device includes a shovel plate and a diversion block. The shovel plate is fixedly installed on the front side of the measuring vehicle. The diversion block is fixedly installed on the surface of the shovel plate. The shovel plate contacts the slide rail. The movement of the measuring vehicle drives the shovel plate to move. The movement of the shovel plate drives the diversion block to move. The shovel plate removes the sediment in the slide rail and discharges it through the diversion block.

[0009] According to the above technical solution, the obstacle clearing device also includes an electric push rod, a connecting button, a connecting rod and a fixed block. The fixed end of the electric push rod is fixedly mounted on the surface of the measuring vehicle, the connecting button is fixedly mounted on the output end of the electric push rod, one side of the connecting rod is rotatably mounted on the inner wall of the connecting button, and the fixed block is fixedly mounted on the top of the measuring vehicle. The output end of the electric push rod extends forward to drive the connecting button to move, and the movement of the connecting button causes the connecting rod to rotate.

[0010] According to the above technical solution, the obstacle clearing device also includes a rotating plate and a push plate. The rotating plate is rotatably mounted on the surface of the fixed block, the other side of the connecting rod is rotatably mounted on the inner wall of the rotating plate, and the push plate is fixedly mounted on the front side of the connecting button. The movement of the connecting button drives the push plate to move at the same time. When the rotating plate temporarily leaves, an obstacle will enter the middle area, and it will be pushed out by the push plate.

[0011] According to the above technical solution, the obstacle clearing device also includes a fixed cylinder and a protective plate. The fixed cylinder is fixedly installed on the front side of the sealing box, and the protective plate is slidably installed on the inner wall of the fixed cylinder. When an obstacle hits the measuring instrument, it is protected by the protective plate.

[0012] According to the above technical solution, the protective device includes an ejection airbag, a trigger plate and an L-shaped push rod. The ejection airbag is arranged inside a sealed box, the trigger plate is rotatably installed at the bottom of the sealed box, and the L-shaped push rod is fixedly installed at the bottom of the protective plate. A No. 2 torsion spring is arranged between the trigger plate and the sealed box, and the trigger plate is reset by the No. 2 torsion spring. When the protective plate is subjected to a severe impact, the trigger plate rotates to open the ejection airbag, and the sealed box gradually floats to the surface under the buoyancy of the formed ejection airbag.

[0013] According to the above technical solution, the protective device also includes a limit block, a right-angle plate, a support plate and a No. 2 spring. The limit block is slidably installed on the inner wall of the measuring vehicle, the right-angle plate is fixedly installed on the bottom of the limit block, the top of the limit block is set as an inclined surface, the support plate is fixedly installed on the right side of the limit block, and the No. 2 spring is set between the right-angle plate and the measuring vehicle. The right-angle plate is reset by the set No. 2 spring, the L-shaped push rod contacts the right-angle plate, and the movement of the right-angle plate drives the limit block to move. The limit block moves to disengage itself from the docking groove. At this time, the sealing box can slide freely on the inner wall of the measuring vehicle.

[0014] The present invention provides a self-propelled slope track measuring device specially used for land space hydrological survey. It has the following beneficial effects: (1) The invention, through the setting of the measuring device, places the tripod at the level of the ramp and completes the installation. Then, the plumb line is used to measure whether the tripod is installed stably. After the installation is stable, the measuring vehicle is moved to contact the slide rail by the lifting mechanism. The hollow block is connected to the measuring vehicle by the installation rod and the No. 1 spring. When the connection needs to be released, the installation rod is pulled to the right to disengage the slot. The measuring vehicle is driven to move along the slide rail by the servo motor and the threaded rod. The ramp is measured by the measuring instrument. In this way, the measuring vehicle moves at a constant speed. The constant speed movement can avoid the measurement error caused by the speed change. In the underwater environment, the water flow, water pressure and other factors may affect the measurement results. The constant speed movement helps to reduce the interference of these external factors and make the measurement data more accurate and reliable. When the measuring vehicle moves underwater, it is unknown whether there are any interference objects underwater. After the measuring vehicle and the hollow block are installed, the connection between the two may be disconnected due to the accidental contact of these interference objects, resulting in the loss of power source of the measuring vehicle. The rotating frame and the blocking block are used to prevent the interference objects from being touched accidentally.

[0015] (2) This invention, through the setting of the obstacle-clearing device, if the precipitation is too heavy, the lower part of the slide rail may be submerged. At this time, under the scouring of the water flow, some mud and sand may enter the slide rail, thereby affecting the normal movement of the measuring vehicle. The mud and sand in the slide rail are shoveled out by the shovel plate and the guide block, and discharged by the guide block to prevent the mud and sand from accumulating on the surface of the shovel plate and causing blockage in the absence of the guide block. When the measuring vehicle moves underwater, there may be floating objects blocking the front. The electric push rod, the connecting button, the connecting rod, and the rotating plate are used to remove the obstacles in front. When the rotating plate is temporarily left, the obstacles will enter the middle area. At this time, the push plate will push it out. The above methods prevent floating objects or sediments in the water from directly hitting the measuring vehicle. When the obstacles hit the measuring instrument, the protective plate is used to protect it.

[0016] (3) This invention, through the setting of the protective device, when the protective plate is subjected to a severe impact, the ejection airbag is opened by means of the L-shaped push rod, the right-angle plate, the second spring, the limit block, the support plate, and the trigger plate. The buoyancy of the ejection airbag after molding causes the sealed box to gradually float to the surface of the water. If the measuring instrument continues to work after the impact, it may record inaccurate data. After the measuring instrument is released to the water surface, it is easier to be discovered and recovered, thereby reducing the risk of equipment loss. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 5, an embodiment of the present invention is: a self-propelled slope track measuring device dedicated to national land space hydrological measurement, including a ramp 1 and a tripod 2. The tripod 2 is arranged above the ramp 1. A lifting mechanism 4 is arranged on the surface of the tripod 2. A plumb line 5 is arranged on the circumferential surface of the tripod 2. A slide rail 7 is arranged on the surface of the ramp 1. It also includes a measuring device. Among them, the measuring device includes a measuring vehicle 8, a sealed box 801, a hollow block 9, a mounting rod 10, a first spring 11, a clamping block 12 and a rotating frame 13. The measuring vehicle 8 is arranged at the connecting end of the lifting mechanism 4. A clamping groove is opened at the wheel of the measuring vehicle 8. The sealed box 801 is slidably installed on the inner wall of the measuring vehicle 8. One side of the hollow block 9 is slidably installed on the inner wall of the slide rail 7. The mounting rod 10 is slidably installed on the inner wall of the hollow block 9. The side of the mounting rod 10 close to the clamping groove is set as an inclined surface. The first spring 11 is arranged between the mounting rod 10 and the hollow block 9. The first spring 11 drives the mounting rod 10 to reset. The clamping block 12 is fixedly installed on the circumferential surface of the mounting rod 10. The rotating frame 13 is rotatably installed on the outer wall of the hollow block 9. A measuring instrument is arranged inside the sealed box 801. A first torsion spring is arranged between the clamping block 12 and the hollow block 9. By moving the rotating frame 13 to the right side of the clamping block 12, the clamping block 12 is limited, that is, the mounting rod 10 cannot be pulled. In this way, false touch caused by touching interference objects is prevented. The first torsion spring drives the clamping block 12 to reset.

[0021] The measuring device further includes a servo motor 14 and a threaded rod 15. The fixed end of the servo motor 14 is fixedly installed on the surface of the slide rail 7. The threaded rod 15 is fixedly installed on the output end of the servo motor 14. The other side of the hollow block 9 is threadedly installed on the circumferential surface of the threaded rod 15. A docking groove is opened on the surface of the sealed box 801, so that the measuring vehicle 8 moves at a constant speed. Moving at a constant speed can avoid measurement errors caused by speed changes. In an underwater environment, factors such as water flow and water pressure may affect the measurement results. Moving at a constant speed helps to reduce the interference of these external factors and makes the measurement data more accurate and reliable.

[0022] When this embodiment works, after the tripod 2 is placed and installed at the horizontal position of the ramp 1, the plumb line 5 is used to measure whether the tripod 2 is installed stably. After the installation is stable, the measuring vehicle 8 is moved to contact the slide rail 7 through the lifting mechanism 4. At this time, the wheels of the measuring vehicle 8 will contact the inclined surface of the mounting rod 10, causing the mounting rod 10 to move to the right and compress the first spring 11 at the same time. When the card slot overlaps with the mounting rod 10, the first spring 11 is released at this time and drives the mounting rod 10 to insert into the card slot. At this time, the position of the measuring vehicle 8 is fixed. When it is necessary to release the fixation, the mounting rod 10 is pulled to the right to disengage from the card slot. At this time, the output end of the servo motor 14 rotates to drive the threaded rod 15 to rotate. The rotation of the threaded rod 15 causes the hollow block 9 to move downward. The movement of the hollow block 9 drives the measuring vehicle 8 to move. The movement of the measuring vehicle 8 drives the sealed box 801 to move, that is, drives the measuring instrument to move underwater. A water quality sensor and a depth sensor are provided in the measuring instrument, which is convenient for measuring relevant hydrological parameters. The measurement is carried out through the measuring instrument. In this way, the measuring vehicle 8 moves at a constant speed. The constant speed movement can avoid measurement errors caused by speed changes. In the underwater environment, factors such as water flow and water pressure may affect the measurement results. The constant speed movement helps to reduce the interference of these external factors and make the measurement data more accurate and reliable. When the measuring vehicle 8 moves underwater, because it is unknown whether there are interfering objects underwater, after the measuring vehicle 8 and the hollow block 9 are installed, the connection between the two may be disconnected by accidentally touching these interfering objects, resulting in the measuring vehicle 8 losing the power source. At this time, the rotating frame 13 is moved to the right side of the clamping block 12, so that the clamping block 12 is limited, that is, the mounting rod 10 cannot be pulled. In this way, anti-mis-touch of the touch by interfering objects is realized.

[0023] Please refer to Figures 1 - 8 , on the basis of the above embodiment, in another embodiment of the present invention, a clearance device for clearing obstacles when the measuring instrument moves and a protection device for protecting the measuring instrument are provided on the front side of the measuring vehicle 8. The clearance device includes a shovel plate 20 and a diversion block 21. The shovel plate 20 is fixedly installed on the front side of the measuring vehicle 8, and the diversion block 21 is fixedly installed on the surface of the shovel plate 20. The shovel plate 20 contacts the slide rail 7. The sediment in the slide rail 7 is removed by the shovel plate 20 and discharged through the diversion block 21 to prevent accumulation on the surface of the shovel plate 20 without the diversion block 21 and cause blockage.

[0024] The clearance device further includes an electric push rod 22, a connection button 23, a connecting rod 24 and a fixed block 25. The fixed end of the electric push rod 22 is fixedly installed on the surface of the measuring vehicle 8, the connection button 23 is fixedly installed on the output end of the electric push rod 22, one side of the connecting rod 24 is rotatably installed on the inner wall of the connection button 23, and the fixed block 25 is fixedly installed on the top of the measuring vehicle 8. When the measuring vehicle 8 moves underwater, there may be floating objects blocking in front. At this time, the output end of the electric push rod 22 extends forward to drive the connection button 23 to move.

[0025] The obstacle removal device also includes a rotating plate 26 and a push plate 27. The rotating plate 26 is rotatably mounted on the surface of the fixed block 25. The other side of the connecting rod 24 is rotatably mounted on the inner wall of the rotating plate 26. The push plate 27 is fixedly mounted on the front side of the connecting button 23. The rotating plate 26 is rotated to remove the front obstacle. When the rotating plate 26 is temporarily left, the obstacle will enter the middle area. At this time, it will be pushed out by the push plate 27. The above method prevents floating objects or sediments in the water from directly hitting the measuring vehicle 8.

[0026] The obstacle removal device also includes a fixed cylinder 28 and a protective plate 29. The fixed cylinder 28 is fixedly installed on the front side of the sealing box 801, and the protective plate 29 is slidably installed on the inner wall of the fixed cylinder 28. When an obstacle hits the measuring instrument, it is protected by the protective plate 29.

[0027] The protective device includes an ejection airbag 30, a trigger plate 31 and an L-shaped push rod 32. The ejection airbag 30 is arranged inside the sealed box 801. The trigger plate 31 is rotatably installed at the bottom of the sealed box 801. The L-shaped push rod 32 is fixedly installed at the bottom of the protective plate 29. A No. 2 torsion spring is arranged between the trigger plate 31 and the sealed box 801. The trigger plate 31 is reset by the No. 2 torsion spring. The sealed box 801 gradually floats to the surface under the buoyancy of the formed ejection airbag 30. If the measuring instrument continues to work after the impact, inaccurate data may be recorded. After the measuring instrument is released to the water surface, it is easier to be discovered and recovered, thereby reducing the risk of equipment loss.

[0028] The protective device also includes a limit block 33, a right-angle plate 34, a support plate 35 and a No. 2 spring 36. The limit block 33 is slidably installed on the inner wall of the measuring vehicle 8, the right-angle plate 34 is fixedly installed at the bottom of the limit block 33, the top of the limit block 33 is set as an inclined surface, the support plate 35 is fixedly installed on the right side of the limit block 33, and the No. 2 spring 36 is set between the right-angle plate 34 and the measuring vehicle 8. The No. 2 spring 36 drives the right-angle plate 34 to reset, and the L-shaped push rod 32 contacts the right-angle plate 34, so that it is separated from the docking groove. At this time, the sealing box 801 can slide freely on the inner wall of the measuring vehicle 8.

[0029] When the embodiment is working, if the precipitation is too large, the lower part of the slide rail 7 may be submerged. At this time, the water flow may cause some mud and sand to enter the slide rail 7, thereby affecting the normal movement of the measuring vehicle 8. At this time, the movement of the measuring vehicle 8 drives the shovel plate 20 to move, and the movement of the shovel plate 20 drives the movement of the guide block 21. The shovel plate 20 removes the mud and sand in the slide rail 7 and discharges it through the guide block 21 to prevent the mud and sand from accumulating on the surface of the shovel plate 20 and causing blockage in the absence of the guide block 21. When the measuring vehicle 8 moves underwater, there may be floating objects blocking the front. At this time, the output end of the electric push rod 22 extends forward to drive the connection button 23 to move, and the movement of the connection button 23 causes the connection rod 24 to rotate. The rotation of the connection rod 24 causes the rotating plate 26 to rotate outward, and the front obstacle is removed by rotating the rotating plate 26. The movement of the connection button 23 drives the push plate 27 to move. When the rotating plate 26 temporarily leaves, the obstacle will enter the middle area, and the push plate 27 will push it out. In this way, floating objects or sediments in the water are prevented from directly hitting the measuring vehicle 8. When the obstacle hits the measuring instrument, it is protected by the protective plate 29; The initial state of the trigger plate 31 is the compressed state of the No. 2 torsion spring, and it is limited by the support plate 35. When the protective plate 29 is hit violently, the protective plate 29 moves backward to drive the L-shaped push rod 32 to move. The movement of the L-shaped push rod 32 will contact the inclined surface of the right-angle plate 34, so that the right-angle plate 34 moves to the right and compresses the No. 2 spring 36. The movement of the right-angle plate 34 drives the limit block 33 to move. The limit block 33 moves to make itself out of the docking groove. At this time, the sealing box 801 can slide freely on the inner wall of the measuring vehicle 8. When the limit block 33 moves, it also drives the support plate 35 to move. The movement of the support plate 35 makes it free from the limit on the trigger plate 31. At this time, the No. 2 torsion spring is released and drives the trigger plate 31 to rotate. The rotation of the trigger plate 31 causes the ejection airbag 30 to be opened. The buoyancy of the formed ejection airbag 30 causes the sealed box 801 to gradually float to the surface. If the measuring instrument continues to work after the impact, inaccurate data may be recorded. After the measuring instrument is released to the water surface, it is easier to be discovered and recovered, reducing the risk of equipment loss.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
