[0017] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0018] This invention provides, for example Figure 1 and Figure 2 The self-balancing surveying device shown includes a surveying machine body 1 and a tripod. The surveying machine body 1 is mounted on the tripod. The tripod includes a fixed part 2 and a movable part 3. An end cap 6 is provided at one end of the fixed part 2, and a clamping plate 5 is provided at one end of the movable part 3. A coarse adjustment mechanism 4 is provided on the end cap 6. The coarse adjustment mechanism 4 is used to adjust the extension and retraction of the movable part 3 of the tripod.
[0019] like Figure 3 As shown, the coarse adjustment mechanism 4 includes a transmission mechanism 41, a coarse adjustment drive motor 42, a lead screw 43, and a nut 44. The coarse adjustment drive motor 42 is located at the input end of the transmission mechanism 41, the lead screw 43 is located at the output end of the transmission mechanism 41, and the nut 44 is located on the lead screw 43 and connected to the clamping plate 5. The coarse adjustment drive motor 42 is driven by the transmission mechanism 41 to rotate the lead screw 43. By acting on the nut 44, the clamping plate 5 and the movable part 3 move together to perform adjustment.
[0020] like Figure 6 and Figure 7 As shown, a coarse level 17 is installed on the main body 1 of the surveying machine. The coarse level 17 is a circular level and includes a level housing, a top cover 171, a wire 172, and conductive liquid droplets 174. The wire 172 is mounted on the top cover 171, and the conductive liquid droplets 174 are located inside the level housing. The level housing is also filled with an insulating liquid with a density greater than that of the conductive liquid droplets 174, allowing the conductive liquid droplets 174 to float on the insulating liquid. The top cover 171 is configured with three control areas, namely areas I, II, and III. The wires 172 for the three control areas... The coarse adjustment mechanism 4 controls one leg. The adjacent wires 172 in each area contact the conductive liquid droplets 174 to realize the passage of the coarse adjustment mechanism 4. The conductive liquid droplets 174 are used to indicate the horizontal state and connect the wires 172. In this application, it is assumed that after the wires 172 are connected, the coarse adjustment mechanism 4 controls the movable part 3 to retract. That is, when the conductive liquid droplets 174 of the coarse adjustment level 17 are biased to one side, it indicates that the biased side is higher. At this time, the wires 172 on that side are connected, causing the corresponding movable part 3 to retract, so that side is lowered, until the conductive liquid droplets 174 move to the middle circular area, and the coarse adjustment is completed.
[0021] like Figure 6 As shown, the surveying machine body 1 is equipped with a fine-tuning knob 13, and a fine-tuning gear 15 is mounted on the knob 13. The fine-tuning gear 15 is connected to a fine-tuning drive motor 16. The fine-tuning knob 13 passes through and is screwed onto a fine-tuning screw 14. The lower end of the fine-tuning screw 14 is rotatably connected to the lower fine-tuning seat 11, and the upper end of the screw 14 passes through and is screwed onto the upper fine-tuning seat 12. The fine-tuning drive motor 16 drives the fine-tuning gear 15 to rotate, causing the fine-tuning screw 14 to rotate, thereby adjusting the height of the upper fine-tuning seat 12 on that side for horizontal fine-tuning of the surveying machine body 1. The surveying machine body 1 is equipped with a fine-tuning level 18, such as... Figure 8 The fine-tuning level 18 is a square level. It has two control areas, left and right, for controlling the fine-tuning drive motor 16. Several wires 172 are also provided in these two areas. The circuit is connected when adjacent wires 172 contact conductive liquid droplets 174. The fine-tuning upper seat 12 of the surveying machine body 1 has contacts 19 corresponding to the number of fine-tuning drive motors 16. Contacts 21 are provided on the edge of the turntable 20 of the surveying machine body 1. Contacts 19 are electrically connected to the fine-tuning drive motors 16, and contacts 21 are electrically connected to the control areas of the fine-tuning level 18. The contacts 19 are spaced evenly. When contacts 21 contact contacts 19, the conductive liquid droplets 174 in the corresponding control areas connect to the wires 172, thereby controlling the fine-tuning drive motor 16. Specifically, such as Figure 9 As shown, contact 19 includes contact 191, contact 192, and contact 193, and contact 21 includes contact 211, contact 212, and contact 213. During fine adjustment, the turntable 20 is rotated so that contact 191 contacts contact 211 and contact 292 contacts contact 212. At this time, the fine adjustment drive motor 16 at the position of contact 191 is connected to the wire 172 of the left area of the corresponding fine adjustment level 18, and the fine adjustment drive motor 16 at the position of contact 292 is connected to the wire 172 of the corresponding fine adjustment level 18. When the conductive liquid droplet 174 is located in the left area, the wire 172 in the left area is connected, and the fine adjustment drive motor 16 at the position of contact 191 rotates. The rotation of the fine-tuning screw 14 causes the fine-tuning upper seat 12 on that side to lower until the conductive liquid droplet 174 moves to the middle area of the fine-tuning level 18. Then, the surveying machine body 1 rotates 90°, so that the contact 3 213 contacts the contact 3 193. At this time, the fine-tuning drive motor 16 at the location of the contact 3 193 is connected to the wires 172 on the left and right sides of the corresponding fine-tuning level 18. When the circuit is connected, the fine-tuning upper seat 12 rises and connects to the right side. When the circuit is connected, the fine-tuning upper seat 12 falls. The specific raising and lowering can be achieved by controlling the forward and reverse rotation of the fine-tuning drive motor 16 at the location of the contact 3 193. At this point, the fine-tuning is completed, and the level can be automatically adjusted when an abnormality occurs during use.
[0022] Specifically, a positioning plate 45 is provided at one end of the lead screw 43. The positioning plate 45 is located inside the movable part 3 and is used to limit one end of the lead screw 43 inside the movable part 3 so that it will not shake randomly.
[0023] Specifically, several branch lines 173 are provided on the conductor 172, and the branch lines 173 of adjacent conductors 172 are alternately arranged to increase the density and facilitate contact with the conductive liquid droplets 174 to achieve energization.
[0024] The present invention also provides an embodiment, such as Figure 4 and Figure 5 As shown, the transmission mechanism 41 includes a transmission mechanism housing 411, a lead screw end gear 412, a switching gear 413, a connecting rod 414, a motor end gear 415, a hand-cranked gear 416, a hand-cranked transmission gear 417, a hand-cranked lever end gear 418, and a hand-cranked lever 419. The lead screw end gear 412 is located at one end of the lead screw 43, the motor end gear 415 is located at one end of the coarse adjustment drive motor 42, the hand-cranked gear 416 is located above the motor end gear 415, the hand-cranked transmission gear 417 is located above the hand-cranked gear 416, the hand-cranked lever end gear 418 is located at one end of the hand-cranked lever 419 and meshes with the hand-cranked transmission gear 417, the switching gear 413 is located between the lead screw end gear 412 and the motor end gear 415, and the switching gear 413 is connected to the connecting rod 414. The connecting rod 414 moves up and down to connect the switching gear 413 to the motor end gear 415 and the hand-cranked gear 416 respectively. An extension shell 421 is provided on the outer casing 411 of the mechanism. An adjusting nut 420 is rotatably mounted on the extension shell 421. One end of the connecting rod 414 is connected to the adjusting screw 423. The adjusting screw 423 is connected to the adjusting nut 420. When the coarse adjustment drive motor 42 is used for driving adjustment, the coarse adjustment drive motor 42 drives the motor end gear 415 to rotate. Through the switching gear 413, it drives the lead screw end gear 412 to rotate, thereby driving the lead screw 43 to rotate for adjustment. When manual adjustment is used, the adjusting nut 420 is rotated, causing the adjusting screw 423 to drive the switching gear 413 to rise. The switching gear 413 disengages from the motor end gear 415 and engages with the hand crank gear 416. At this time, the hand crank 419 is rotated. Through the hand crank end gear 418, it drives the hand crank transmission gear 417 to rotate. Then, through the hand crank gear 416, the switching gear 413, and the lead screw end gear 412, it drives the lead screw 43 to rotate for manual adjustment.
[0025] Specifically, a guide post 422 is also provided inside the housing 411 of the transmission mechanism. The guide post 422 extends into the connecting rod 414 and serves to fix the switching gear 413.
[0026] Specifically, a locking lever 424 is provided inside the adjusting screw 423. One end of the locking lever 424 extends to one side of the switching gear 413. When the locking lever 424 is pressed, one end of the locking lever 424 is locked between the teeth of the switching gear 413, fixing the switching gear 413 so that the switching gear 413 will not rotate arbitrarily, thus playing a locking role.
[0027] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
