[0020] Refer to Figures 1 to 7 , a geographic information measurement and positioning acquisition device, comprising an adjustable tripod 1, a support disk 2, a protective cylinder 3, a protective cover 4 and a cleaning mechanism 5; the lower end of the adjustable tripod 1 is detachably inserted into the ground, the support disk 2 is hingedly arranged at the upper end of the adjustable tripod 1 on the ground, a groove 21 is formed on the upper end surface of the support disk 2, the protective cylinder 3 is sleeved and rotatably arranged in the groove 21, the protective cover 4 is slidably penetrated through the protective cylinder 3, a probe for acquiring information and a central control unit are installed in the protective cover 4, and the protective cover 4 is configured to be made of a transparent material, and the cleaning mechanism 5 is arranged between the support disk 2 and the protective cylinder 3; Wherein, the cleaning mechanism 5 includes a rotating assembly 6 and a moving assembly 7, the rotating assembly 6 is arranged at the lower end of the protective cylinder 3, and the moving assembly 7 is arranged at the upper end of the protective cylinder 3.

[0021] Among them, the probe in the protective cover 4 can collect geographical information within a certain area and import the collected information into the central control unit. The central control unit integrates the data and transmits it to the ground display device so that the staff can observe the specific geographical information.

[0022] In addition, the adjustable tripod 1 can be automatically extended or shortened through manual control to adapt to different geographical areas. The adjustment principle of the adjustable tripod 1 is prior art and will not be elaborated here.

[0023] As a preferred embodiment, the rotating assembly 6 includes a motor box 61, a stepping motor 62, a screw 63, a clamping block 64, a first gear 65 and a T-shaped connecting rod 66; the motor box 61 is fixed at the center of the lower end of the support disk 2, the stepping motor 62 is fixedly installed on the inner wall of the bottom of the motor box 61, a threaded hole is opened in the center of the support disk 2, the screw 63 is threadedly connected to the threaded hole, and the protective cover 4 is fixedly installed at the upper end of the screw 63. A rectangular hole is opened in the lower end of the screw 63, a rectangular shaft is fixed to the output end of the stepping motor 62, and the rectangular shaft is slidably arranged in the rectangular hole. The clamping block 64 is fixed on the side wall of the screw 63 above the support disk 2. A clamping groove is opened in the first gear 65, the first gear 65 is slidably arranged on the screw 63, and the clamping block 64 is slidably arranged through the clamping groove. A T-shaped ring groove 22 is opened on the upper end surface of the support disk 2, one end of the T-shaped connecting rod 66 is fixed to the lower end surface of the first gear 65, and the other end is sleeved and rotatably arranged in the T-shaped ring groove 22.

[0024] For details, please refer to Figure 3 , when the stepping motor 62 is started, the stepping motor 62 will drive the rectangular shaft to rotate, and the rectangular shaft drives the screw 63 to rotate through the extrusion effect on the inner wall of the rectangular hole. When the screw 63 rotates, it cooperates with the threaded hole, so that the screw 63 will move spirally up and down, and then can drive the protective cover 4 to move spirally up and down synchronously. When the screw 63 rotates, it drives the first gear 65 to rotate through the clamping block 64, and when the first gear 65 rotates, the T-shaped connecting rod 66 has a limiting effect on the first gear 65 in the vertical direction to ensure that the first gear 65 only produces rotational motion.

[0025] It should be explained that when the screw 63 drives the protective cover 4 to enter and exit the protective cylinder 3, the clamping block 64 is always above the support disk 2.

[0026] Among them, when the protective cover 4 is moved out of the protective cylinder 3, it is in the information collection state, and when the protective cover 4 is moved into the protective cylinder 3, it is in the closed collection state, so as to avoid scratches on the protective cover 4 caused by tree branches during the movement of the whole device, resulting in refraction when the probe inside it receives the light source, and avoiding affecting the accuracy of the information collection image.

[0027] As a preferred embodiment, the rotating assembly 6 further includes an internal gear 67, a first sleeve rod 68, a second gear 69, a double-toothed ring 601, a second sleeve rod 602, a third gear 603, a fourth gear 604, a linkage rod 605 and a pinion gear 606; the internal gear 67 is fixed inside the lower end of the protective cylinder 3, the first sleeve rod 68 is sleeved and rotatably arranged inside the upper end of the support disk 2, the second gear 69 is fixed on the first sleeve rod 68, and the second gear 69 meshes with the first gear 65 and the internal gear 67 respectively. A gear groove 31 is formed on the inner wall of the protective cylinder 3.

The second sleeve rod 602 is sleeved and rotatably arranged inside the upper end of the support disk 2. The third gear 603 is fixed on the second sleeve rod 602, and the third gear 603 meshes with the second gear 69. The fourth gear 604 is fixed on the second sleeve rod 602, and the fourth gear 604 meshes with the inner tooth ring of the double-toothed ring 601. A plurality of cylindrical grooves are formed in the inner circumference of the side wall of the protective cylinder 3, and the cylindrical grooves communicate with the gear groove 31. A plurality of linkage rods 605 are provided, and are respectively rotatably arranged in the plurality of cylindrical grooves. A plurality of pinion gears 606 are arranged on the circumference, and are respectively fixed to the lower ends of the plurality of linkage rods 605, and the plurality of pinion gears 606 all mesh with the outer tooth ring of the double-toothed ring 601.

[0028] For details, please refer to Figure 3 , the rotation of the first gear 65 will drive the rotation of the second gear 69, thereby driving the rotation of the internal gear 67, further driving the rotation of the protective cylinder 3, and the rotation direction of the protective cover 4 is the same as that of the first gear 65, while the rotation direction of the protective cylinder 3 is the same as that of the internal gear 67. Therefore, the rotation direction of the protective cylinder 3 is opposite to that of the protective cover 4. When the second gear 69 rotates, it will drive the rotation of the third gear 603. The rotation of the third gear 603 will drive the rotation of the second sleeve rod 602, thereby driving the rotation of the fourth gear 604. The fourth gear 604 will drive the rotation of the double-toothed ring 601, and the double-toothed ring 601 meshes with the plurality of pinion gears 606 to drive the synchronous rotation of the plurality of linkage rods 605. That is to say, when the protective cylinder 3 is revolving, the plurality of linkage rods 605 inside the protective cylinder 3 will rotate synchronously.

[0029] As a preferred embodiment, the moving component 7 includes a first bevel gear 71, a sleeve shaft 72, a second bevel gear 73, a T-shaped column 74, a guide block 75, a rotating shaft 76, a cleaning roller 77 and a return spring 78; a plurality of rectangular through holes are circumferentially formed on the upper side wall of the protective cylinder 3, a T-shaped guide groove is formed on the inner wall of the upper end of the rectangular through hole, and the rectangular through hole communicates with the cylindrical groove. A plurality of first bevel gears 71 are circumferentially arranged and are respectively fixed to the upper ends of a plurality of linkage rods 605. A plurality of sleeve shafts 72 are arranged and are respectively sleeved and rotatably arranged on one side wall of the rectangular through hole. A plurality of second bevel gears 73 are arranged and are respectively fixed to the plurality of sleeve shafts 72, and the first bevel gear 71 meshes with the second bevel gear 73. A plurality of T-shaped columns 74 are respectively slidably penetrated and arranged in a plurality of T-shaped guide grooves. A plurality of guide blocks 75 are arranged and are respectively fixed to the lower ends of the plurality of T-shaped columns 74. Extension blocks 751 are fixed to both sides of one end where the plurality of guide blocks 75 are close to each other. A plurality of rotating shafts 76 are rotatably penetrated and arranged in the two extension blocks 751. A plurality of cleaning rollers 77 are respectively fixed to the plurality of rotating shafts 76. A wiping cotton is arranged on the outer surface of the cleaning roller 77. A straight slot 752 is formed in the guide block 75, the sleeve shaft 72 is slidably arranged in the straight slot 752, a slider 753 is slidably arranged in the straight slot 752, and the slider 753 is in movable contact with the sleeve shaft 72. The return spring 78 is connected between the slider 753 and the inner wall of the straight slot 752.

[0030] For details, please refer to Figure 4 , when the protective cover 4 moves upward, the plurality of cleaning rollers 77 will push the guide block 75 to move synchronously toward the outside of the protective cylinder 3 under the extrusion force of the protective cover 4. When the protective cover 4 moves downward, it will move synchronously toward the inside of the protective cylinder 3 under the elastic force of the return spring 78. That is to say, the plurality of cleaning rollers 77 are always in a movable contact state with the surface of the protective cover 4.

[0031] As a preferred embodiment, the moving component 7 further includes a driving wheel 79, a connecting roller 80, a first tension wheel 81, a second tension wheel 82 and a track wheel 83; a plurality of driving wheels 79 are arranged and are respectively fixed to one end of the plurality of sleeve shafts 72 away from the second bevel gear 73. A plurality of connecting rollers 80 are arranged and are respectively fixed to one end of the plurality of guide blocks 75 away from the rotating shaft 76. A plurality of second tension wheels 82 are arranged and are respectively fixed to the plurality of rotating shafts 76. Among them, a triangle is formed among the driving wheel 79, the first tension wheel 81 and the second tension wheel 82. A plurality of track wheels 83 are arranged and are respectively meshed with the plurality of driving wheels 79, the first tension wheel 81 and the second tension wheel 82.

[0032] For details, please refer to Figures 5 to 6, when the linkage rod 605 rotates, it will drive the sleeve shaft 72 to rotate through the meshing of the first bevel gear 71 and the second bevel gear 73, thereby driving the driving wheel 79 to rotate. The driving wheel 79 drives the track wheel 83 to rotate by meshing with the track wheel 83, thereby driving the two tension wheels to rotate. The second tension wheel 82 can drive the rotating shaft 76 to rotate, thereby driving the cleaning roller 77 to rotate.

[0033] Specifically, please refer to Figure 5 , when the driving wheel 79 rotates quickly clockwise along with the sleeve shaft 72, the guide block 75 moves slowly to the left, and the first tension wheel 81 and the second tension wheel 82 will move to the left synchronously. During this process, the driving wheel 79 is always in a state of rotating quickly clockwise. It should be noted here that due to the fast rotation speed of the driving wheel 79 and the slow moving speed of the track wheel 83, the driving wheel 79 can accelerate the clockwise rotation of the track wheel 83, so as to drive the two tension wheels to rotate clockwise. Moreover, during the above process, the track wheel 83 on the right side of the driving wheel 79 bears the tight side, and the track wheel 83 on the left side of the driving wheel 79 bears the loose side. Therefore, during the slow leftward movement of the guide block 75, the track wheel 83 can drive stably clockwise.

[0034] When the driving wheel 79 rotates quickly counterclockwise along with the sleeve shaft 72, the guide block 75 will move slowly to the right, and the first tension wheel 81 and the second tension wheel 82 will move to the right synchronously. During this process, the driving wheel 79 is always in a state of rotating quickly counterclockwise. Similarly, due to the fast rotation speed of the driving wheel 79 and the slow moving speed of the track wheel 83, the driving wheel 79 can accelerate the counterclockwise rotation of the track wheel 83, so as to drive the two tension wheels to rotate counterclockwise. Moreover, during the above process, the track wheel 83 on the left side of the driving wheel 79 bears the tight side, and the track wheel 83 on the right side of the driving wheel 79 bears the loose side. Therefore, during the slow rightward movement of the guide block 75, the track wheel 83 can drive stably counterclockwise.

[0035] Specifically, when the protective cover 4 spirally moves upward clockwise from inside the protective cylinder 3, the cleaning roller 77 will rotate counterclockwise along with the protective cylinder 3, and at the same time, multiple cleaning rollers 77 will rotate synchronously toward the inner side of the protective cylinder 3. Similarly, when the protective cover 4 spirally moves downward counterclockwise from outside the protective cylinder 3, the cleaning roller 77 will rotate clockwise along with the protective cylinder 3, and at the same time, multiple cleaning rollers 77 will rotate synchronously toward the outer side of the protective cylinder 3. Therefore, whether the protective cover 4 moves upward or downward, multiple protective covers 4 can perform counter-flushing friction cleaning on the surface of the protective cover 4 in the circumferential and vertical directions, thereby increasing the relative rotation speed. Furthermore, the contact times between the same point of the cleaning roller 77 and the protective cover 4 increase, and the cleaning is more thorough.

[0036] As a preferred embodiment, an L-shaped hole 9 is formed in the T-shaped column 74 and the guide block 75. A pressing block 91 is hermetically and slidably penetrated through the inner side of the L-shaped hole 9 close to the protective cylinder 3. A damping spring 92 is connected between the pressing block 91 and the inner wall of the L-shaped hole 9. A blocking block 93 is rotatably arranged in the inner side of the L-shaped hole 9 far from the protective cylinder 3. A steering column 94 is fixed to the upper end of the blocking block 93. The steering column 94 is sleeved and rotatably arranged in the side wall of the L-shaped hole 9. A compression spring 95 is connected between the side wall of the L-shaped hole 9 and the steering column 94. A cleaning liquid is arranged in the L-shaped hole 9 between the blocking block 93 and the pressing block 91.

[0037] That is to say, when the guide block 75 moves, the inner wall of the T-shaped guide groove of the protective cylinder 3 will squeeze the pressing block 91, and the cleaning liquid in the L-shaped hole 9 can be extruded and sprayed onto the cleaning cotton on the cleaning roller 77. That is to say, when the cleaning cotton is cleaning the protective cover 4, it always remains in a wet state, so as to improve the cleaning effect.

[0038] In summary, through the drive of the stepping motor 62, the present application can not only move the probe in the protective cylinder 3, but also drive a plurality of cleaning rollers 77 to fit the surface of the protective cover 4 and perform circumferential and vertical counterflush wiping and cleaning during the movement of the protective cylinder 3, improving the automatic cleaning ability and the cleaning effect on the protective cover 4. Moreover, during the cleaning process, the cleaning cotton can be sprayed with liquid to keep the cleaning cotton always in a wet state, thereby further improving the cleaning effect on the protective cover 4.

[0039] As a preferred embodiment, a feed hole is formed in the L-shaped hole 9, and a cover 96 is detachably and hermetically arranged on the feed hole. That is to say, when the cleaning liquid in the L-shaped hole 9 is used up, the cover 96 is opened, the cleaning liquid is added, and then the cover 96 is covered.

[0040] Specifically, during implementation, first, the adjustable tripod 1 is fixedly installed on the ground, and then the length of the adjustable tripod 1 is adjusted so that the probe adapts to different geographical regions. Subsequently, the stepping motor 62 is started forward. The stepping motor 62 can drive the probe to spiral upward from the protective cylinder 3. Moreover, while driving the rotation of multiple guide blocks 75, it can drive multiple cleaning rollers 77 to rotate synchronously inward. Thus, during the outward movement of the protective cover 4, a one-time counter-flush wiping and cleaning can be completed, thereby ensuring that the light transmittance of the protective cover 4 remains in the best state during the information collection process. During the wiping process, the pressing block 91 will be pressed once, so that the cleaning cotton always remains moist during rotation, improving the cleaning efficiency. When the protective cover 4 moves to the target position, the stepping motor 62 is turned off. After the collection work is completed, the stepping motor 62 is started in reverse. By the same token, the stepping motor 62 can drive the probe to spiral downward from the protective cylinder 3. Moreover, while driving the rotation of multiple guide blocks 75, it can drive multiple cleaning rollers 77 to rotate synchronously outward. Thus, during the inward movement of the protective cover 4, another one-time counter-flush wiping and cleaning can be completed to ensure that the surface of the protective cover 4 remains clean when it moves into the protective cylinder 3, avoiding the hardening of debris on the surface of the protective cover 4 after entering the protective cylinder 3 during the collection process, and avoiding difficulty in cleaning during the second use. When the protective cover 4 completely enters the protective cylinder 3, the stepping motor 62 is turned off. Subsequently, the adjustable tripod 1 is removed, and thus a one-time information collection is completed.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
