[0002] In water conservancy projects, single or several different action, different types and different water structures are often used to regulate water flow to meet the needs of different departments for water resources. These buildings built for water conservancy and water damage control are called water structures, which play a role in controlling and regulating water flow, preventing water damage and developing and utilizing water resources, and are an important part of achieving the goals of water conservancy projects. When the water structure is constructed, a corresponding number of L-shaped settlement observation nails are arranged on the outer wall of the water structure as settlement observation points for settlement measurement of the water structure.

[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] This invention provides a device for measuring the settlement of hydraulic structures, such as... Figures 1-14As shown, the hydraulic structure settlement measurement device includes: a support 1 and a U-shaped clamp 75 mounted on the support 1 for holding a leveling rod 2; a threaded cylinder 3 rotatably mounted in the mounting groove of the support 1; a threaded rod 4 threadedly mounted on the threaded cylinder 3 for adjusting the height of the U-shaped clamp 75; a counterweight 39 mounted on one side of the U-shaped clamp 75 for adjusting the leveling rod 2 horizontally; a centering mechanism mounted on the support 1 for centering the leveling rod 2 directly above the observation nail, the centering mechanism including: a connecting plate 5 fixedly mounted on one side of the support 1; a rectangular gear ring 6 slidably mounted on one side of the connecting plate 5, one side of the rectangular gear ring 6 having a centering plate 8 for assisting in placing the support 1 and an extension plate 9 slidably mounted on the centering plate 8; a toothed gear 7 rotatably mounted on the connecting plate 5 for driving the rectangular gear ring 6 and the centering plate 8 to reciprocate left and right; and a drive mechanism mounted on the support 1 for driving the threaded cylinder 3 to rotate.

[0035] In this embodiment, the counterweight 39 uses gravity to drive the U-shaped clamp 75 to be placed horizontally, and then the leveling rod 2 is fixed on the U-shaped clamp 75 to achieve the initial horizontal setting of the leveling rod 2. The threaded cylinder 3 is driven to rotate by the drive mechanism. Since the threaded rod 4 is threaded on the threaded cylinder 3, the height of the threaded rod 4 and the U-shaped clamp 75 is adjusted so that the leveling rod 2 reaches a suitable height (higher than the observation nail on the wall).

[0036] Next, support 1 is placed on one side of the observation nail, so that the observation nail is located between the two supports 1. The drive mechanism is restarted, so that the leveling rod 2 slides down to contact the observation nail. At the same time, the toothed gear 7 rotates to drive the rectangular gear ring 6 and the centering plate 8 to move back and forth. A set of centering plates 8 and extension plates 9 move back and forth relative to each other, so that a set of centering plates 8 or extension plates 9 contact the observation nail. Then the position of support 1 is adjusted to ensure that the leveling rod 2 and the observation nail are on the same vertical axis. After the leveling rod 2 contacts the top of the observation nail, the drive mechanism is turned off. Then, a tripod and a level are set up to conduct settlement measurement. The leveling rod 2 is automatically placed horizontally by the counterweight 39, which overcomes the problem that it is difficult to ensure the leveling rod is horizontal when manually supported at high places. This effectively improves the accuracy of the settlement measurement of hydraulic structures. The height of the leveling rod 2 can be easily adjusted by using the drive mechanism, and the alignment of the leveling rod 2 and the observation nail can be achieved by the centering mechanism, which effectively improves the efficiency of the measurement work.

[0037] In a further preferred embodiment of the present invention, a connecting cylinder 11 is fixedly installed inside the base 10 of the support 1, and a connecting plate 12 is fixedly installed on one side of the other base 10. The connecting plate 12 is slidably connected to the connecting cylinder 11, and a screw rod 13 is threadedly installed on the connecting cylinder 11.

[0038] In this embodiment, when it is necessary to adjust the distance between the two supports 1, either support 1 can be pulled manually. Since the connecting plate 12 can slide within the connecting cylinder 11, the connecting plate 12 slides relative to the connecting cylinder 11, thereby achieving flexible adjustment of the distance between the two supports 1. After adjusting to a suitable distance, the connecting plate 12 is fixed in its current position by tightening the screw rod 13 to make it press against the connecting plate 12, preventing the two supports 1 from sliding relative to each other again and ensuring the stability of the device during use. The distance between the two supports 1 can be adjusted according to actual needs. This flexibility allows the device to adapt to the requirements of different specifications of observation nails and different measurement environments. After the measurement work is completed, the distance between the two supports 1 can be reduced by adjustment, which can effectively reduce the overall space occupied by the device, making it convenient to store and transport, reducing storage and transportation costs, and also making it easy to carry to different measurement locations.

[0039] In a further preferred embodiment of the present invention, the driving mechanism includes: a rectangular telescopic rod 14 rotatably mounted on two supports 1; a mounting cavity opened in the support 1; bevel gears 15 respectively disposed on the mounting cavity and the threaded cylinder 3, the two bevel gears 15 meshing with each other; a connecting port opened at the bottom of the mounting cavity; a set of sprockets 16 respectively disposed on the connecting port and the rotating shaft of the bevel gears 15 located on one side of the mounting cavity, a chain 17 sleeved on the set of sprockets 16, and the sprockets 16 located in the connecting port being fixedly connected to the rotating shaft of the rectangular telescopic rod 14; and a motor 18 fixedly mounted in the mounting groove of the support 1 for driving the threaded cylinder 3 to rotate, the output shaft of the motor 18 being fixedly connected to the rotating shaft of the sprockets 16 located in the connecting port.

[0040] In this embodiment, when the motor 18 starts, the output shaft rotates, driving the sprocket 16 connected to it to rotate. Through the transmission action of the chain 17, the two sprockets 16 rotate synchronously, thereby driving the bevel gear 15 on one side of the mounting cavity to rotate. When the bevel gear 15 rotates, it will drive the bevel gear 15 on the threaded cylinder 3 to rotate. Since the transmission of the two sets of sprockets 16 on the two supports 1 is carried out through the rectangular telescopic rod 14, the threaded cylinder 3 on the two supports 1 can be rotated synchronously.

[0041] The function of the rectangular telescopic rod 14 is to ensure that the distance between the two supports 1 is adjustable while still transmitting power stably, so that the two threaded cylinders 3 keep moving synchronously. When the threaded cylinder 3 rotates, the threaded rod 4 will move up and down with the rotation of the threaded cylinder 3, thereby driving the U-shaped telescopic frame 19 to slide up and down. Through the combined transmission of the sprocket 16, chain 17 and bevel gear 15, the threaded cylinders 3 on the two supports 1 rotate synchronously, thereby driving the two threaded rods 4 to drive the related components (such as the U-shaped telescopic frame 19 and the leveling rod 2) to slide up and down synchronously.

[0042] In a further preferred embodiment of the present invention, the top end of the threaded rod 4 is provided with a sliding mechanism for driving a set of U-shaped clamps 75 to slide relative to each other. The sliding mechanism includes: a U-shaped telescopic frame 19 fixedly installed at the top end of the threaded rod 4; lead screws 20 rotatably installed on both sides of the inner wall of the U-shaped telescopic frame 19; a rectangular threaded sleeve 21 threaded onto the lead screws 20; a connecting box 22 rotatably installed on one side of the rectangular threaded sleeve 21, one side of the connecting box 22 being in contact with the U-shaped clamps 75; and a transmission mechanism provided on the U-shaped telescopic frame 19 for driving the two lead screws 20 to rotate.

[0043] In this embodiment, when the U-shaped clamp 75 is needed to clamp the leveling rod 2, the transmission mechanism starts to work, synchronously driving the two lead screws 20 to rotate. When the lead screws 20 rotate, the rectangular threaded sleeve 21 moves along the axial direction of the lead screws 20. As the rectangular threaded sleeve 21 moves to one side, the connecting box 22 also moves accordingly, thereby pushing the U-shaped clamp 75 to move. Under this driving action, the two U-shaped clamps 75 slide relative to each other, gradually approach each other, and finally clamp onto the leveling rod 2. In addition, an anti-slip pad is installed inside the U-shaped clamp 75. The anti-slip pad is in close contact with the leveling rod 2, increasing the friction. By synchronously driving the two lead screws 20 to rotate through the transmission mechanism, the precision of the lead screw transmission can enable the two U-shaped clamps 75 to slide relative to each other and accurately clamp onto the leveling rod 2 in the appropriate position, ensuring that the leveling rod 2 is fixed in position during the measurement process and will not shake or shift, thereby effectively improving the accuracy of settlement measurement.

[0044] In a further preferred embodiment of the present invention, the transmission mechanism includes: a rectangular telescopic rod 25 rotatably mounted on one side of the U-shaped telescopic frame 19; two sets of sprockets 26 respectively fixedly sleeved on both ends of the rectangular telescopic rod 25 and on two lead screws 20, each set of sprockets 26 being fitted with a chain 27; a handle 28 fixedly mounted on one end of the lead screw 20; and a telescopic protective cover 29 mounted on the U-shaped telescopic frame 19 for protecting the two sets of sprockets 26 and the chain 27.

[0045] In this embodiment, when the leveling rod 2 needs to be clamped, the operator rotates the handle 28 to drive the lead screw 20 to rotate. When one of the lead screws 20 rotates, the sprocket 26 will rotate accordingly. Through the transmission action of the chain 27, the rectangular telescopic rod 25 will rotate. The rotation of the rectangular telescopic rod 25 will drive the sprocket 26 at its other end to rotate. Then, through the chain 27 at that end, the rotational force will be transmitted to the sprocket 26 on the other lead screw 20, so that the two lead screws 20 will rotate synchronously. The synchronous rotation of the two lead screws 20 will drive the rectangular threaded sleeve 21 threaded on them to move, thereby driving the U-shaped clamp 75 to slide relative to each other to clamp the leveling rod 2. In addition, the telescopic protective cover 29 can protect the two sets of sprockets 26 and chains 27, preventing external debris, dust and other objects from entering and affecting the normal operation of the transmission mechanism. At the same time, it can also prevent the operator from accidentally contacting the transmission components and getting injured during operation.

[0046] In a further preferred embodiment of the present invention, a slide rod 23 is fixedly installed inside the connecting box 22, and a slider 24 is slidably installed on the slide rod 23. One side of the slider 24 is fixedly connected to the U-shaped clamp 75. A switch device 43 for turning off the motor 18 is fixedly installed on the top of the inner wall of the connecting box 22, and a contact rod 44 for turning the switch device 43 on and off is fixedly installed on one side of the slider 24.

[0047] In this embodiment, when the entire device performs a settlement measurement operation, the threaded rod 4 continues to descend under the drive mechanism, which in turn drives the U-shaped telescopic frame 19 to descend, and the U-shaped clamp 75 descends accordingly. As the threaded rod 4 continues to descend, the leveling rod 2 gradually approaches and eventually contacts the observation nail. At this time, the threaded rod 4 will continue to descend due to inertia or the drive mechanism not stopping in time, causing the connecting box 22 to continue to descend as well. During the descent of the connecting box 22, the contact rod 44 on the slider 24 will gradually approach and eventually contact the switching device 43. Once the contact rod 44 contacts the switching device 43, the switching device... When the backup mechanism 43 is triggered, it sends a command to shut down motor 18, causing the entire drive mechanism to stop. At this time, the U-shaped clamp 75 stops moving, and the leveling rod 2 is stably fixed on the observation nail for subsequent settlement measurement. Through the ingenious design of the slider 24, the contact rod 44, and the switch device 43, the function of automatically shutting down motor 18 after the leveling rod 2 contacts the observation nail is realized. This automatic control method avoids the reaction delay or operation error that may occur in manual operation, and can accurately stop the drive mechanism when the leveling rod 2 reaches the appropriate position, ensuring that the leveling rod 2 is accurately fixed on the observation nail.

[0048] In a further preferred embodiment of the present invention, a fixing cylinder 30 is fixedly installed on one side of the centering plate 8, and a fixing rod 31 is fixedly installed on one side of the rectangular toothed ring 6. The fixing rod 31 is slidably connected to the fixing cylinder 30, and a buffer spring 32 is fixedly installed inside the fixing cylinder 30. One end of the buffer spring 32 is fixedly connected to the fixing rod 31.

[0049] In this embodiment, when the centering plate 8 or the extension plate 9 is reciprocating, if it comes into contact with the observation nail, at the moment of contact, the centering plate 8 or the extension plate 9 is blocked by the observation nail, and its movement trend is suppressed. At this time, the fixing rod 31 will slide relative to the fixing cylinder 30 and compress the buffer spring 32. After being compressed, the buffer spring 32 will undergo elastic deformation. According to the elastic characteristics of the spring, it will generate a spring force opposite to the compression direction. This spring force will react on the fixing rod 31, thereby buffering the centering plate 8 or the extension plate 9 and preventing the centering plate 8 or the extension plate 9 from directly colliding with the observation nail.

[0050] In a further preferred embodiment of the present invention, an elastic band 33 is detachably installed on one side of the centering plate 8, the bottom end of the elastic band 33 is detachably connected to the extension plate 9, and a support wheel 40 for supporting and limiting the rectangular threaded sleeve 21 is fixedly installed on one side of the inner wall of the U-shaped telescopic frame 19.

[0051] In this embodiment, when the leveling rod 2 descends and contacts the extension plate 9, since an elastic band 33 is detachably installed on one side of the centering plate 8 and the bottom end of the elastic band 33 is detachably connected to the extension plate 9, the elastic band 33 will be subjected to tension. The elastic band 33 itself has a certain elasticity and will undergo elastic deformation under tension, generating a downward elastic force. This elastic force will be transmitted to the extension plate 9, so that the extension plate 9 can slide down simultaneously with the leveling rod 2, avoiding the extension plate 9 from hindering the descent of the leveling rod 2, ensuring that the leveling rod 2 can descend smoothly to the appropriate position for measurement. The support wheel 40 plays a supporting and limiting role on the rectangular threaded sleeve 21, so that the rectangular threaded sleeve 21 can move smoothly and horizontally.

[0052] In a further preferred embodiment of the present invention, the toothed gear 7 and the threaded cylinder 3 are provided with a linkage mechanism for synchronously driving the threaded cylinder 3 and the toothed gear 7 to rotate. The linkage mechanism includes: a fixed cover mounted on the support 1, the fixed cover covering the threaded cylinder 3; a set of sprockets 34 disposed on the fixed cover and the threaded cylinder 3, a chain 35 sleeved on the set of sprockets 34; a sprocket 4 36 rotatably mounted on one side of the connecting plate 5 and the support 1, a chain 4 37 sleeved on the set of sprockets 4 36; and bevel gears 2 38 respectively fixedly mounted on the rotating shaft of any of the chain 4 37 and the rotating shaft of the sprocket 34 located on the fixed cover, the two bevel gears 2 38 meshing with each other.

[0053] In this embodiment, when the threaded cylinder 3 starts to rotate, the toothed gear 7 is synchronously driven to rotate through the linkage mechanism. When the threaded cylinder 3 rotates, it drives the sprocket 34 on it to rotate. The sprocket 34 transmits power to the chain 35, causing the sprocket 34 on the fixed cover to rotate as well. When the shaft of the sprocket 34 on the fixed cover rotates, it drives the bevel gear 38 fixedly mounted on that shaft to rotate. Through the meshing of the two bevel gears 38, power is transmitted to the shaft of the chain 37, causing the chain 37 to drive the other connected sprockets 36 to rotate, thus transmitting the rotational force to the toothed gear 7, thereby achieving synchronous rotation of the toothed gear 7. The linkage mechanism, through the combination of sprockets, chains, and bevel gears, can accurately and synchronously transmit the rotational power of the threaded cylinder 3 to the toothed gear 7, ensuring that the toothed gear 7 and the threaded cylinder 3 rotate synchronously according to a predetermined transmission ratio.

[0054] In a further preferred embodiment of the present invention, a limiting cylinder 41 is fixedly installed on one side of the support 1, a limiting rod 42 for guiding the threaded rod 4 is fixedly installed on the support plate of the support wheel 40, and a storage box 45 for storing the counterweight 39 is fixedly installed on one side of the support 1.

[0055] In this embodiment, the sliding of the limiting rod 42 along the limiting cylinder 41 plays a crucial role in ensuring the smooth movement of the threaded rod 4. When the threaded rod 4 rises and drives the leveling rod 2 to move, the smooth movement ensures that the leveling rod 2 can accurately reach the designated position for measurement, avoiding positional deviation of the leveling rod 2 caused by the shaking of the threaded rod 4. The counterweight 39 is stored in the storage box 45 for easy subsequent transportation of this equipment.

[0056] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments:

[0057] In another embodiment of the present invention, a partition 46 is fixedly installed inside the storage box 45, the partition 46 divides the storage box 45 into a storage cavity and an installation cavity, a telescopic cover 47 is provided on the top of the storage box 45, a heater 48 for outdoor heating in winter is provided inside the telescopic cover 47, a battery 49 for supplying power to the heater 48 is installed in the installation cavity, a solar panel 50 is fixedly installed on the top of the telescopic cover 47, and a controller 51 is fixedly installed on one side of the storage box 45.

[0058] In this embodiment, when conducting settlement measurement work for hydraulic engineering outdoors in winter, if the operator needs to keep warm, the heater 48 installed in the telescopic cover 47 can be activated by the controller 51. The heater 48 generates heat to provide warmth for the operator working in the cold environment. The installation of the curtain 52 in the operating opening of the telescopic cover 47 can not only ensure that the heater 48 dissipates heat normally, but also block the cold air from the outside to a certain extent, thereby improving the heating effect.

[0059] When an external power source is available, the battery 49 can be charged to store sufficient electrical energy. When outdoors without an external power source, the battery 49 releases the stored electrical energy to power the heater 48, ensuring its continuous operation. The solar panel 50 converts solar energy into electrical energy during the day when there is sunlight. This electrical energy can directly charge the battery 49 or be stored for later use. The charging function of the solar panel 50 allows renewable energy to replenish the battery 49, reducing reliance on traditional external power sources and improving the device's endurance in the field. Operators can control the heater 48's on / off state, adjust its power output, and monitor the battery 49's charge level in real time via the controller 51, facilitating the management and operation of the device's heating and power supply functions.

[0060] In another embodiment of the present invention, the telescopic cover 47 and the storage box 45 are provided with a height adjustment mechanism for adjusting the height of the telescopic cover 47. The height adjustment mechanism includes: two threaded cylinders 53 fixedly installed on the top of the storage box 45; two threaded rods 54 rotatably installed on the top of the inner wall of the telescopic cover 47, the threaded rods 54 being threadedly connected to the threaded cylinders 53; a drive wheel 55 fixedly sleeved on the two threaded rods 54, and a belt 56 sleeved on the two drive wheels 55; a motor 57 fixedly installed inside the telescopic cover 47 for driving the rotation of the threaded rods 54; and bevel gears 58 fixedly sleeved on the output shaft of either threaded rod 54 and the motor 57, the two bevel gears 58 meshing with each other.

[0061] In this embodiment, when the telescopic cover 47 is retracted, the second motor 57 is started, and the output shaft of the second motor 57 begins to rotate. The rotation of the output shaft of the second motor 57 will drive the threaded rod 54 connected to it to rotate synchronously. According to the principle of belt drive, the first belt 56 will transmit power to the drive wheel 55 on the other threaded rod 54, thereby driving the other threaded rod 54 to rotate as well, so as to realize the synchronous rotation of the two threaded rods 54.

[0062] When the threaded rod 54 rotates, according to the characteristics of the threaded drive, the threaded rod 54 will move in a straight line along the threaded cylinder 53. Since the threaded cylinder 53 is fixed on the storage box 45, the threaded rod 54 actually drives the telescopic cover 47 to move up and down relative to the storage box 45. When the threaded rod 54 rotates in the forward direction, the telescopic cover 47 slides up along the storage box 45, and the height increases; when the threaded rod 54 rotates in the reverse direction, the telescopic cover 47 slides down, and the height decreases to store the heater 48.

[0063] In another embodiment of the present invention, the telescopic cover 47 is provided with a storage mechanism for storing the heater 48. The storage mechanism includes: a mounting block fixedly installed on the top of the inner wall of the telescopic cover 47; a one-way screw 59 rotatably installed on the mounting block; a fixing block 60 threadedly sleeved on the one-way screw 59, the fixing block 60 being hinged to the top of the heater 48; two drive wheels 61 respectively provided on the telescopic cover 47 and the threaded rod 54, with belts 62 sleeved on the two drive wheels 61; bevel gears 63 respectively fixedly sleeved on the shaft of the drive wheels 61 located on the telescopic cover 47 and on the one-way screw 59, the two bevel gears 63 meshing with each other; and an angle adjustment mechanism provided on one side of the one-way screw 59 for driving the heater 48 to rotate.

[0064] In this embodiment, when the heater 48 is finished being used and needs to be stored, the second motor 57 is started. The second motor 57 drives the threaded rod 54, which is connected to it through the bevel gear 3 58, to rotate. The rotation of the threaded rod 54 will drive the drive wheel 61 located on the telescopic cover 47 to rotate through the belt 62. The rotation of the drive wheel 61 will drive the one-way screw 59 to rotate.

[0065] When the one-way screw 59 rotates, the fixed block 60 will move in a straight line along the one-way screw 59. Since the fixed block 60 is hinged to the top of the heater 48, the fixed block 60 will drive the heater 48 to move to one side. After the second motor 57 is started, the second threaded rod 54 rotates. At the same time, the second threaded rod 54 is threadedly connected to the second threaded cylinder 53. According to the principle of the height adjustment mechanism, the telescopic cover 47 will move downward to cooperate with the storage of the heater 48. As the heater 48 moves to one side, the angle adjustment mechanism located on one side of the one-way screw 59 starts to work. The angle adjustment mechanism applies a force to the heater 48, causing the heater 48 to rotate around its hinge point with the fixed block 60, gradually rotating from a vertical state to a horizontal state, and finally completing the storage. Using a motor 57 as a power source, the transmission system consisting of a drive wheel 61, a belt 62, and a bevel gear 63 realizes the rotation of the one-way screw 59, which in turn drives the fixed block 60 to move the heater 48. At the same time, combined with the downward movement of the telescopic cover 47 and the adjustment of the angle of the heater 48 by the angle adjustment mechanism, the entire storage process can be completed in one continuous motion.

[0066] In another embodiment of the present invention, the angle adjustment mechanism includes: a rotating drum 64 rotatably mounted on the top of the inner wall of the telescopic cover 47; a pull rope 65 wound around the rotating drum 64, one end of the pull rope 65 being fixedly connected to the bottom end of the heater 48; drive wheels 66 respectively disposed on one side of the one-way screw 59 and the mounting block, and belts 67 being sleeved on the two drive wheels 66; and bevel gears 68 respectively fixedly sleeved on the shafts of the drive wheels 66 and the rotating drum 64 located on the mounting block, the two bevel gears 68 meshing with each other.

[0067] In this embodiment, when the one-way screw 59 rotates under the drive of the second motor 57, it will drive the third belt 67 to move, thereby causing the third drive wheel 66 to rotate. The rotation of the third drive wheel 66 will drive the rotating shaft of the rotating drum 64 to rotate, thereby causing the rotating drum 64 to rotate. When the rotating drum 64 rotates, the pull rope 65 wound on the rotating drum 64 will be wound up as the rotating drum 64 rotates. As the pull rope 65 is continuously wound up, the pull rope 65 will apply a leftward pulling force to the bottom end of the heater 48. Under the action of the leftward pulling force of the pull rope 65, the heater 48 will rotate to the left around its hinge point with the fixed block 60, thereby realizing the adjustment of the heater 48 from a vertical state to a horizontal state, and completing the angle adjustment.

[0068] In another embodiment of the present invention, the U-shaped telescopic frame 19 is provided with a limiting mechanism for fixing the support 1 to the tripod. The limiting mechanism includes: a mounting plate 69 fixedly installed on one side of the U-shaped telescopic frame 19; a slide block 70 slidably disposed in the fixing groove of the mounting plate 69; a limiting seat 71 fixedly installed at one end of the slide block 70 and adapted to the threaded opening of the tripod; a return spring 72 fixedly installed in the fixing groove and at one end of the slide block 70; and a top rod 73 fixedly installed on one side of the support 1, the top rod 73 contacting the legs of the tripod.

[0069] In this embodiment, when it is necessary to perform measurement work at the next observation point, after the equipment on the support 1 is stored, the device is fixed to the tripod of the level instrument by the strap 74. At the same time, it is ensured that the position of the mounting plate 69 is higher than the platform of the tripod to provide suitable space and position conditions for subsequent limiting operations. Then, the operator manually pulls the slide 70 to make it slide in the fixing groove of the mounting plate 69. Since the limiting seat 71 is fixedly installed at one end of the slide 70, the limiting seat 71 also moves with the slide 70. At the same time, during the process of pulling the slide 70, the return spring 72 is stretched, producing elastic deformation and storing elastic potential. Yes, when the slide 70 is pulled to the appropriate position, aligning the limit seat 71 with the threaded opening of the tripod platform, and the limit seat 71 is inserted into the threaded opening, releasing the slide 70 will cause the return spring 72 to attempt to return to its original natural state, generating a reverse pulling force on the slide 70. This will cause the slide 70 to tightly engage the limit seat 71 within the threaded opening, thus limiting the movement of the equipment and securing it firmly to the tripod. Through the engagement of the limit seat 71 with the threaded opening of the tripod platform, and the elastic action of the return spring 72, the equipment is securely fixed to the tripod. Even during tripod movement, including bumps and shaking, the equipment can be effectively prevented from detaching from the tripod, avoiding damage and ensuring the smooth progress of the measurement work.

[0070] In summary, compared with related technologies, the automatic horizontal placement of the leveling rod by using counterweights overcomes the difficulty of ensuring the leveling rod is horizontal at a high position when manually supported, effectively improving measurement accuracy. At the same time, the height of the leveling rod can be easily adjusted using the drive mechanism, and the centering mechanism ensures that the leveling rod and the observation nail are accurately aligned, greatly improving the efficiency of measurement work.
