[0002] Surveying and mapping equipment is an important tool for measuring and mapping spatial information such as terrain, landforms, and buildings. It uses different technologies and principles to obtain various measurement data of the target area with high precision, and converts it into graphics, images or digital information for subsequent analysis, design or planning. Among them, the outdoor remote sensing multifunctional surveying and mapping device is an advanced equipment that integrates remote sensing technology and multifunctional surveying and mapping functions. It is mainly used in outdoor environments to obtain spatial information such as terrain, landforms, and buildings through remote sensing means, and convert it into high-precision graphics, images or digital information for subsequent analysis, design or planning.

[0003] When existing surveying and mapping devices are used outdoors, they are mostly fixed by inserting a part of the device into the bottom of the soil, and then data is collected. However, when the surveying and mapping device is fixed outdoors by inserting it into the soil, due to the physical properties of the soil (such as water content, compactness, etc.) and external factors (such as people walking, equipment weight, etc.), it is inevitable that sinking and offset will occur, resulting in changes in the originally set measurement reference surface, which directly affects the accuracy and reliability of the surveying and mapping results.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] 1. The present invention can automatically complete the vertical and horizontal resetting of the surveying and mapping device when it is inserted into the bottom of the soil and fixed and sinks and deviates through the mutual cooperation of the control mechanism, the adjustment and fixing mechanism, the air supply mechanism, the driving mechanism and the auxiliary fixing mechanism. When the surveying and mapping device sinks and deviates greatly, the conical block of the surveying and mapping device that sinks and deviates can be quickly fixed in the soil to prevent it from continuing to sink and reduce the possibility of subsequent collapse due to sparse soil or external force. After the fixation is completed, the vertical and horizontal resetting is automatically completed, thereby effectively reducing the errors in the subsequent surveying and mapping process without manual adjustment, thereby effectively ensuring the accuracy and reliability of the surveying and mapping results while improving the overall efficiency of the surveying and mapping work.

[0022] 2. The present invention, through the mutual cooperation of the control mechanism, the adjusting and fixing mechanism and the air supply mechanism, can, when a certain fixed rod in the surveying and mapping device sinks and deviates, that is, when the support frame sinks and deviates, utilize the rolling of the metal ball in the control mechanism and the contact of the metal ball with the pressure sensor (the pressure sensor corresponds to the above-mentioned fixed rod) to start the electric push rod in the air supply mechanism, so that the push plate rises in the air groove and squeezes the air, and the squeezed air is sent into the corresponding first extrusion groove through the opening of the first bellows, the air pipe and the corresponding solenoid valve. At this time, the internal pressure of the first extrusion groove increases, so that the connecting rod rises, thereby completing the vertical resetting of the support frame, and then the support frame is in a horizontal state.

[0023] 3. The present invention can utilize the rising of the connecting rod to make the connecting plate rise and squeeze the air in the second extrusion groove by adjusting the cooperation between the fixing mechanism, the air supply mechanism and the driving mechanism. The squeezed air is transmitted to the inside of the docking block through the second bellows, and applies thrust to the slide plate, thereby moving the slide plate and the latching teeth on the slide plate, and then causing the gear meshing with the latching teeth to rotate counterclockwise. The rotation of the gear can cause the rotating shaft to rotate counterclockwise, thereby causing the connecting piece, the sliding rod and the connecting rod to rotate coaxially. The rotation of the sliding rod and the connecting rod can cause the support frame to move horizontally in the direction of the sinking deviation of the fixing rod, and then after completing the vertical resetting of the support frame, the horizontal resetting of the support frame can be completed immediately, thereby reducing the error in the subsequent surveying and mapping process and effectively ensuring the accuracy and reliability of the surveying and mapping results.

[0024] 4. The present invention can increase the force of the metal ball in the control mechanism contacting the pressure sensor when a certain fixed rod in the surveying and mapping device has a large sinking deviation through the mutual cooperation of the control mechanism and the auxiliary fixing mechanism. When the pressure sensor senses that the pressure has reached a certain value, the electromagnetic block will be activated, so that the strong magnetic block squeezes the spring and slides along the inner wall of the fixed rod toward the electromagnetic block, thereby releasing the limit on the pressure block and causing it to fall. The falling of the pressure block can enable the extrusion plate to squeeze the polyurethane foam, and the arrangement of the nozzle, the extrusion groove and the connecting groove can be used to spray the squeezed polyurethane foam to the outside of the conical block. At this time, the polyurethane foam will solidify rapidly under the action of air, thereby causing the polyurethane foam to squeeze the soil outside the conical block, increasing the soil density outside the conical block, so that the conical block can be fixed in the soil before the reset operation is performed to prevent it from continuing to sink and reduce the possibility of subsequent collapse due to sparse soil or external force, thereby providing a strong guarantee for the subsequent reset operation.

DETAILED DESCRIPTION

Pressure sensors 33 are installed on the end side walls. The directions of the other ends of the three groups of slide grooves 31 correspond to the positions of the three groups of connecting frames 13, and metal balls 32 are placed at the connection of the three groups of slide grooves 31. The diameter of the metal ball 32 is slightly smaller than the diameter of the slide groove 31. The bottom ends of the three groups of connecting frames 13 are provided with adjustment and fixing mechanisms for fixing the entire device horizontally in the soil. The adjustment and fixing mechanisms include a connecting rod 4. A first extrusion groove 42 is penetrated at the bottom end of the connecting rod 4. A sliding rod 5 is slidably connected in the first extrusion groove 42. A connecting piece 52 is fixedly connected to the bottom end of the sliding rod 5. A rotating shaft 54 ​​is installed at the bottom end of the connecting piece 52. The connecting piece 52 is rotatably connected to a docking block 6 through the rotating shaft 54. The interior of the docking block 6 is hollow. The rotating shaft 54 ​​is located inside the docking block 6. The bottom end of the docking block 6 is fixedly connected to a fixing rod 7, and the bottom end of the fixing rod 7 is fixedly connected to a conical block 78.

[0040] When surveying is required, the distance between the connecting rod 4 and the sliding rod 5 is adjusted, and then the three sets of fixing rods 7 are made to form a triangle and fixed. At this time, the surveying position of the surveying instrument 12 set on the adjustment module 11 can be adjusted by remote sensing equipment.

[0041] Reference Figures 2 to 6 The fixed block 2, the cover shell 21 and the connecting rod 4 are jointly provided with an air supply mechanism for injecting air into the first extrusion groove 42. The air supply mechanism includes an electric push rod 23 and an air groove 25. The electric push rod 23 is fixedly installed inside the cover shell 21. The air groove 25 is opened in the fixed block 2. The output end of the electric push rod 23 passes through the bottom wall of the fixed block 2 and is fixedly connected with a push plate 24. The push plate 24 is sealingly and slidably connected in the air groove 25. A cavity is opened inside the connecting rod 4. The cavity is located above the first extrusion groove 42, and an air pipe 41 is installed in the cavity. An electromagnetic valve 411 is installed on the air pipe 41, and one end of the air pipe 41 is connected with the inside of the first extrusion groove 42. A through hole is opened at the inner side wall of the air groove 25 near the top position, and a first bellows 26 is installed on the through hole. The end of the first bellows 26 away from the through hole passes through the outer wall of the connecting rod 4 and is connected to the other end of the air pipe 41. The first bellows 26 is a hose.

[0042] When one of the three groups of fixed rods 7 sinks and deviates, the support frame 1 will tilt. At this time, the support frame 1 will drive the calibration block 3 to move synchronously, and the metal ball 32 will roll from the inside to the outside along the inner wall of the slide groove 31 corresponding to the fixed rod 7 that has sunk and deviated under the action of gravity until the metal ball 32 contacts the pressure sensor 33. Then the pressure sensor 33 will generate an electrical signal and send it to the controller 22. At this time, the controller 22 will start the electric push rod 23, and the electric push rod 23 will make the push plate 24 slide upward along the inner wall of the air groove 25 opened inside the fixed block 2. The push plate 2 The sliding movement of the connecting rod 4 will squeeze the air in the air groove 25, so that the gas in the air groove 25 enters the air pipe 41 through the first bellows 26. At this time, the controller 22 will synchronously start the electromagnetic valve 411 corresponding to the fixed rod 7 that has sunk and deviated. When the electromagnetic valve 411 is opened, the air will enter the first extrusion groove 42 through the air pipe 41. At this time, the internal pressure of the first extrusion groove 42 increases, so that the connecting rod 4 slides upward along the outer wall of the sliding rod 5. Therefore, when the support frame 1 sinks and deviates, it is compensated by the sliding of the connecting rod 4, so that the support frame 1 can be kept horizontal again.

[0043] Reference Figures 2 to 8 , a driving mechanism is provided on the connecting rod 4, the sliding rod 5 and the docking block 6 for driving the rotating shaft 54 ​​to rotate, the driving mechanism includes a blowing assembly and a slide plate 61, the slide plate 61 is slidably connected to the inner bottom wall of the docking block 6, a through groove is penetrated on one side of the docking block 6, and a long strip-shaped latching tooth 62 is fixedly connected to the side of the slide plate 61 away from the through groove, a gear 55 is installed on the rotating shaft 54, the gear 55 is located above the latching tooth 62, and the gear 55 and the latching tooth 62 are meshed with each other, the blowing assembly is arranged on the connecting rod 4 and the sliding rod 5, and is used to apply a thrust to the slide plate 61, the blowing assembly includes a second extrusion groove 51 and a lifting component, the second extrusion groove 51 is opened inside the sliding rod 5, and the second extrusion groove 51 is sealed and slidably connected with the connecting plate 44, the inner wall of the second extrusion groove 51 is penetrated with a through opening near the top position, and a through opening is penetrated on the connecting rod 4 The corresponding movable groove is arranged in a vertical strip shape, and a second bellows 53 is installed in the through-port. The end of the second bellows 53 away from the through-port passes through the movable groove and is fixedly connected to the through-port on the docking block 6. The second bellows 53 is a hose. The lifting component is arranged inside the sliding rod 5, and the lifting component is located below the second extrusion groove 51, which is used to move the connecting plate 44 upward. The lifting component includes a sliding cavity, which is opened inside the sliding rod 5, and a connecting block 43 is slidably connected in the sliding cavity. Two groups of protrusions are symmetrically installed on the connecting block 43. Two groups of openings for the two groups of protrusions to pass through and lift are opened on the inner wall of the sliding cavity. The outward ends of the two groups of protrusions pass through the two groups of openings respectively and are fixedly connected to the inner wall of the first extrusion groove 42. A connecting column is installed on the top of the connecting block 43. The top of the connecting column passes through the top wall of the sliding cavity and is fixedly connected to the connecting plate 44.

[0044] When the connecting rod 4 slides, it will drive the connecting block 43 to move synchronously, and the movement of the connecting block 43 will drive the connecting plate 44 to move synchronously. At this time, the connecting plate 44 will slide upward along the inner wall of the second extrusion groove 51 opened inside the slide rod 5, so that the connecting plate 44 will squeeze the air inside the second extrusion groove 51, so that the air inside the second extrusion groove 51 enters the interior of the docking block 6 through the second bellows 53. At this time, the air will generate a thrust on the slide plate 61 inside the docking block 6, so that the slide plate 61 slides from the outside to the inside along the inner wall of the docking block 6. Since the latch teeth 62 on the slide plate 61 are engaged with the gear 55, the sliding of the slide plate 61 will cause the gear 55 to rotate, thereby driving the rotating shaft 54 ​​to rotate counterclockwise along the inner wall of the docking block 6. The rotation of the rotating shaft 54 ​​will cause the connecting member 52 to rotate coaxially, and the connecting member 52 will pass The sliding rod 5 and the connecting rod 4 drive the connecting frame 13 to rotate along the inner wall of the support frame 1. When the fixed rod 7 sinks and deviates, although the support frame 1 can be in a horizontal state by moving the connecting rod 4 upward, this method can only change the inclination angle of the support frame 1 relative to the ground, and does not change the deviation of its overall position. The rotation of the sliding rod 5 and the connecting rod 4 can make the support frame 1 move horizontally along the direction of the sinking deviation of the fixed rod 7, so that the support frame 1 can completely return to the position when the fixed rod 7 has not sunk and deviated through compensation in the vertical and horizontal directions. Further, when a group of fixed rods 7 sink and deviate, the support frame 1 and the surveying instrument 12 on the support frame 1 can be reset by compensation, thereby reducing errors in subsequent surveying and mapping processes and effectively ensuring the accuracy and reliability of the surveying and mapping results.

[0045] Reference Figures 9 to 12The fixing rod 7 and the conical block 78 are provided with an auxiliary fixing mechanism for quickly fixing the conical block 78 that has sunk and deviated in the soil. The auxiliary fixing mechanism includes a liquid reservoir 76 and an extrusion assembly. The liquid reservoir 76 is provided inside the fixing rod 7, and polyurethane foam is provided inside the liquid reservoir 76. An extrusion groove is provided at the center of the bottom end of the conical block 78, and the extrusion groove is connected to the inside of the liquid reservoir 76. A nozzle 77 is installed at the connection between the liquid reservoir 76 and the extrusion groove, and a uniformly penetrating nozzle 77 is provided on the inner wall of the extrusion groove. A plurality of connecting grooves 79 are provided, and an extrusion assembly is arranged inside the fixed rod 7, and is used to downwardly squeeze the polyurethane foam inside the liquid storage tank 76. The extrusion assembly includes a drop groove and a force-applying component. The drop groove is opened inside the fixed rod 7, and the drop groove is located above the liquid storage tank 76. A pressure plate 75 is sealed and slidably connected in the drop groove. A plug rod is installed at the bottom end of the pressure plate 75. The bottom end of the plug rod passes through the bottom wall of the drop groove and is fixedly connected with an extrusion plate. The extrusion plate is located inside the liquid storage tank 76, and the extrusion plate is located above the polyurethane foam. The force component is arranged in the drop groove, and the force-applying component is located above the pressure plate 75, and is used to apply pressure to the pressure plate 75. The force-applying component includes a mounting frame, which is fixedly mounted on the fixing rod 7, and the interior of the mounting frame is connected to the interior of the drop groove. Two groups of electromagnetic blocks 71 are symmetrically mounted on the inner wall of the mounting frame, and the opposite ends of the two groups of electromagnetic blocks 71 are fixedly connected with springs 73, and the two groups of electromagnetic blocks 71 are fixedly connected with strong magnetic blocks 72 through springs 73. The two groups of strong magnetic blocks 72 jointly clamp and fix a pressure block 74, and the pressure block 74 is located in the drop groove. The fixing rod 7 and the conical block 78 are made of stainless steel. Since polyurethane foam has a certain degree of corrosiveness, and stainless steel has good durability and corrosion resistance, the service life of the fixing rod 7 and the conical block 78 is effectively ensured. Moreover, since the stainless steel material also has the characteristics of high strength, the conical block 78 can be better inserted into the soil, and at the same time, it can adapt to different types of soil conditions, effectively improving the wide adaptability of the conical block 78.

[0046] When a group of fixed rods 7 undergoes a large downward displacement, the metal ball 32 will roll faster along the slide groove 31, thereby increasing the force exerted by the metal ball 32 on the pressure sensor 33. When the pressure sensor 33 senses that the pressure has reached a certain value, the pressure sensor 33 will send a signal to the controller 22. At this time, the controller 22 will start the electromagnetic block 71, so that the electromagnetic block 71 will generate suction to the strong magnetic block 72, so that the strong magnetic block 72 squeezes the spring 73 and slides along the inner wall of the fixed rod 7 toward the electromagnetic block 71. At this time, the two groups of strong magnetic blocks 72 will release the limit on the pressure block 74, and then the pressure block 74 will fall downward under the action of gravity until the pressure block 74 contacts the pressure plate 75. At this time, the pressure block 74 will generate an impact force on the pressure plate 75, so that the extrusion plate slides downward along the inner wall of the liquid storage tank 76 and squeezes the polyurethane foam, thereby causing the liquid storage tank 76 to be filled with water. The polyurethane foam is sprayed by the nozzle 77 into the extrusion groove and the multiple connecting grooves 79 opened inside the conical block 78, and then the polyurethane foam will be sprayed along the extrusion groove and the connecting groove 79 to the outside of the conical block 78. At this time, the polyurethane foam will solidify rapidly under the action of the air, so that the polyurethane foam will squeeze the soil outside the conical block 78, so that the soil density outside the conical block 78 is increased, so that the conical block 78 can be fixed in the soil, avoiding it from continuing to sink and reducing the possibility of subsequent collapse due to sparse soil or external force. After completing the fixation of the sunken conical block 78, the controller 22 will start the electric push rod 23 and repeat the above operation, so that the support frame 1 completes automatic resetting, ensuring that the surveying and mapping instrument 12 is in a horizontal and stable state without manual adjustment, thereby effectively ensuring the accuracy and reliability of the surveying and mapping results while improving the overall efficiency of the surveying and mapping work.

[0047] In the present invention, when surveying is required, the distance between the connecting rod 4 and the sliding rod 5 is adjusted, and then the three groups of fixing rods 7 are made to form a triangle and fixed. At this time, the surveying orientation of the surveying instrument 12 set on the adjustment module 11 can be adjusted by remote sensing equipment.

[0048] Since the surveying and mapping devices are often fixed outdoors, when the surveying and mapping devices are inserted into the bottom of the soil and fixed, it is inevitable that sinking and offset will occur, which will affect the accuracy of the surveying and mapping. When one of the three groups of fixed rods 7 sinks and deviates, the support frame 1 will tilt. At this time, the support frame 1 will drive the calibration block 3 to move synchronously, and the metal ball 32 will be affected by gravity and roll from the inside to the outside along the inner wall of the slide groove 31 corresponding to the fixed rod 7 that has sunk and deviated, until the metal ball 32 contacts the pressure sensor 33. After that, the pressure sensor 33 will generate an electrical signal and send it to the controller 22. At this time, the controller 22 will start the electric push rod 23, and the electric push rod 23 will cause the push plate 24 to slide upward along the inner wall of the air groove 25 opened inside the fixed block 2. The push plate 2 The sliding movement of the connecting rod 4 will squeeze the air in the air groove 25, so that the gas in the air groove 25 enters the air pipe 41 through the first bellows 26. At this time, the controller 22 will synchronously start the electromagnetic valve 411 corresponding to the fixed rod 7 that has sunk and deviated. When the electromagnetic valve 411 is opened, the air will enter the first extrusion groove 42 through the air pipe 41. At this time, the internal pressure of the first extrusion groove 42 increases, so that the connecting rod 4 slides upward along the outer wall of the sliding rod 5. Therefore, when the support frame 1 sinks and deviates, it is compensated by the sliding of the connecting rod 4, so that the support frame 1 can be kept horizontal again.

[0049] When the connecting rod 4 slides, it will drive the connecting block 43 to move synchronously, and the movement of the connecting block 43 will drive the connecting plate 44 to move synchronously. At this time, the connecting plate 44 will slide upward along the inner wall of the second extrusion groove 51 opened in the sliding rod 5, so that the connecting plate 44 will squeeze the air inside the second extrusion groove 51, so that the air inside the second extrusion groove 51 enters the interior of the docking block 6 through the second bellows 53. At this time, the air will generate a thrust on the slide plate 61 inside the docking block 6, so that the slide plate 61 slides from the outside to the inside along the inner wall of the docking block 6. Since the latch teeth 62 on the slide plate 61 are engaged with the gear 55, the sliding of the slide plate 61 will cause the gear 55 to rotate, thereby driving the rotating shaft 54 ​​to rotate counterclockwise along the inner wall of the docking block 6. The rotation of the rotating shaft 54 ​​will cause the connecting piece 52 to rotate coaxially, and the connecting rod 4 will slide upward along the inner wall of the second extrusion groove 51. The connector 52 will drive the connecting frame 13 to rotate along the inner wall of the support frame 1 through the sliding rod 5 and the connecting rod 4. When the fixed rod 7 sinks and deviates, although the support frame 1 can be placed in a horizontal state by moving the connecting rod 4 upward, this method can only change the inclination angle of the support frame 1 relative to the ground, and does not change the deviation of its overall position. The rotation of the sliding rod 5 and the connecting rod 4 can make the support frame 1 move horizontally along the direction of the sinking deviation of the fixed rod 7, so that the support frame 1 can completely return to the position when the fixed rod 7 has not sunk and deviated through compensation in the vertical and horizontal directions, and then when a group of fixed rods 7 sink and deviate, the surveying instrument 12 can be reset by compensation, thereby reducing errors in subsequent surveying and mapping processes and effectively ensuring the accuracy and reliability of the surveying and mapping results.

[0050] When a group of fixed rods 7 undergoes a large downward displacement, the metal ball 32 will roll faster along the slide groove 31, thereby increasing the force exerted by the metal ball 32 on the pressure sensor 33. When the pressure sensor 33 senses that the pressure has reached a certain value, the pressure sensor 33 will send a signal to the controller 22. At this time, the controller 22 will start the electromagnetic block 71, so that the electromagnetic block 71 will generate suction to the strong magnetic block 72, so that the strong magnetic block 72 squeezes the spring 73 and slides along the inner wall of the fixed rod 7 toward the electromagnetic block 71. At this time, the two groups of strong magnetic blocks 72 will release the limit on the pressure block 74, and then the pressure block 74 will fall downward under the action of gravity until the pressure block 74 contacts the pressure plate 75. At this time, the pressure block 74 will generate an impact force on the pressure plate 75, so that the extrusion plate slides downward along the inner wall of the liquid storage tank 76 and squeezes the polyurethane foam, thereby causing the liquid storage tank 76 to be filled with water. The polyurethane foam is sprayed by the nozzle 77 into the extrusion groove and the multiple connecting grooves 79 opened inside the conical block 78, and then the polyurethane foam will be sprayed along the extrusion groove and the connecting groove 79 to the outside of the conical block 78. At this time, the polyurethane foam will solidify rapidly under the action of the air, so that the polyurethane foam will squeeze the soil outside the conical block 78, so that the soil density outside the conical block 78 is increased, so that the conical block 78 can be fixed in the soil, avoiding it from continuing to sink and reducing the possibility of subsequent collapse due to sparse soil or external force. After completing the fixation of the sunken conical block 78, the controller 22 will start the electric push rod 23 and repeat the above operation, so that the support frame 1 completes automatic resetting, ensuring that the surveying and mapping instrument 12 is in a horizontal and stable state without manual adjustment, thereby effectively ensuring the accuracy and reliability of the surveying and mapping results while improving the overall efficiency of the surveying and mapping work.
