Description

Technical Field

[0001] This invention relates to the field of engineering surveying technology, specifically to a vertical surveying instrument for engineering surveying. Background Technology

[0002] With the advancement of science, new types of surveying instruments have gradually emerged in the construction industry. Simply put, these are instruments and devices designed and manufactured for data acquisition, processing, and output in surveying operations. They are various instruments used for orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry in the planning, design, construction, and management stages of engineering construction. Surveying instruments have made them more convenient for people to use.

[0003] However, in windy weather, existing surveying instruments are subject to significant lateral forces. If the center of gravity cannot be adjusted, the equipment is prone to swaying due to instability, which affects measurement accuracy. Furthermore, strong winds bring a large amount of dust, which contaminates the surveying instrument's lens. Dust can cause blurring on the lens surface, reducing image quality and affecting the measurement accuracy and precision of the surveying instrument. Summary of the Invention

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figures 1-9This technical solution provides a vertical surveying instrument for engineering surveying, specifically including a base plate 1. A first threaded rod 2 is rotatably mounted on the top of the base plate 1. A surveying mechanism 3 is mounted on the top of the first threaded rod 2. The surveying mechanism 3 includes a support plate 301, a surveying instrument 304, and a vertical plate 307. The support plate 301 is rotatably mounted on the top of the first threaded rod 2. A protective cover 302 is fixedly mounted on the top of the support plate 301. A mounting plate 303 is fixedly mounted on the top of the protective cover 302. The surveying instrument 304 is fixedly mounted on the top of the mounting plate 303. The surveying instrument 304 can perform surveying work on the entire engineering environment. A protective cover is fixedly mounted on the top of the mounting plate 303. The protective cover 305 has an observation window 306 fixedly opened at the front. A vertical plate 307 is fixedly installed inside the protective cover 302. The protective cover 305 protects the surveying instrument 304 from moisture corrosion in rainy or snowy weather, allowing the device to be used in such conditions without being affected by the weather, thus accelerating the work progress. The vertical plate 307 is fixedly connected to the support plate 301. A fixing plate 308 is fixedly installed on the top of the vertical plate 307. Two limit plates 309 are fixedly installed on the top of the base plate 1. Each limit plate 309 has a telescopic rod 310 fixedly installed on its top. The device is equipped with a first water tank 311, with a drain outlet 315 at its bottom. The first water tank 311 is threadedly connected to the first threaded rod 2. As the water inside the first water tank 311 gradually increases, it slides downwards on the surface of the first threaded rod 2 under the influence of gravity. As the water inside the first water tank 311 increases, its position moves further downwards, and the center of gravity of the entire device changes due to the gravity of the water itself. A rotating rod 312 is rotatably mounted on the top of the fixed plate 308, and an anemometer 313 is fixedly mounted on the top of the rotating rod 312. The bottom of the fixed plate 308... A wind speed sensor 314 is fixedly installed on the part, and the wind speed sensor 314 is connected to the rotating rod 312. An adjustment mechanism 4 is installed on the side of the vertical plate 307. When the staff are conducting surveying work, they often encounter strong winds and heavy rain in the field. In order not to affect the progress of the project, the staff need to conduct surveying work in the rain. In windy weather, the wind will blow the anemometer 313 to rotate. The speed of rotation of the anemometer 313 is related to the strength of the wind. The rotation of the anemometer 313 can act on the wind speed sensor 314. The wind speed sensor 314 can control other power devices according to the speed of rotation of the anemometer 313.

[0031] Reference Figures 1-9Based on the same concept as Embodiment 1 above, this embodiment also proposes an adjustment mechanism 4 including a motor 401. The motor 401 is controlled by a wind speed sensor 314. The greater the wind speed, the faster the output end of the motor 401 rotates, and vice versa. The motor 401 is fixedly installed on the side of the vertical plate 307, and the output end of the motor 401 extends through the side of the vertical plate 307. A rotating shaft 402 is fixedly installed on the output end of the motor 401, and the motor 401 can drive the rotating shaft 402 to rotate. A toggle lever 403 is fixedly installed on the side of the rotating shaft 402, and the rotation of the rotating shaft 402 can drive the toggle lever 403 to rotate. The vertical plate 307 is rotatably mounted with a rotating cylinder 404 inside. A connecting plate 405 is fixedly mounted on the side of the rotating cylinder 404, and a stop bar 406 is fixedly mounted on the side of the connecting plate 405. When the actuating rod 403 rotates, the rotating actuating rod 403 can move the stop bar 406, thereby driving the connecting plate 405 and the rotating cylinder 404 to rotate. A connecting rod 407 is rotatably mounted at the end of the connecting plate 405, and a second threaded rod 408 is rotatably mounted at the bottom of the connecting rod 407. Horizontal plates 409 are fixedly mounted on both sides of the vertical plate 307, and the second threaded rod 408 passes through to the bottom of the horizontal plate 409. The connecting plate 405 is slidably connected to the horizontal plate 409. The rotation of the connecting plate 405 can drive the second threaded rod 408 to slide up and down inside the horizontal plate 409. The speed at which the second threaded rod 408 moves up and down is related to the wind speed. A first pulley 410 is rotatably mounted on the top of the horizontal plate 409. The first pulley 410 is threadedly connected to the second threaded rod 408. Under the drive of the second threaded rod 408, the first pulley 410 rotates. A sliding cylinder 411 is fixedly mounted on the bottom of the horizontal plate 409. A circular plate 412 is fixedly mounted on the bottom of the second threaded rod 408. A first... Spring 413 is disposed between the inner wall of the circular plate 412 and the sliding cylinder 411. A sliding rod 414 is fixedly installed at the bottom of the circular plate 412. A first toothed plate 415 is fixedly installed on both sides of the sliding rod 414. When the second threaded rod 408 moves upward, it will compress the first spring 413. When the second threaded rod 408 moves downward, the first spring 413 will release elastic potential energy, pulling the second threaded rod 408 downward, increasing the downward force of the second threaded rod 408. When the second threaded rod 408 moves up and down, it will also drive the first toothed plate 415 to move up and down.

[0032] Reference Figures 1-9Based on the same concept as Embodiment 1 above, this embodiment also proposes that a first threaded cylinder 416 is slidably installed inside the vertical plate 307. Two first threaded cylinders 416 are provided, and a third threaded rod 417 is threadedly installed inside each of the two first threaded cylinders 416. A first gear 418 is fixedly installed at the end of the third threaded rod 417. The first gear 418 meshes with a first toothed plate 415. The up and down movement of the first toothed plate 415 can drive the first gear 418 to reciprocate, which in turn can drive the third threaded rod 417 to reciprocate. Therefore, the first threaded cylinder 416 can reciprocate and slide on the vertical plate 307. The side of the vertical plate 307 is fixed. A main cylinder 419 is installed, and a piston 420 is slidably installed inside the main cylinder 419. A first limiting rod 424 is slidably installed inside the piston 420. A connecting column 421 is fixedly installed on the side of the piston 420. The connecting column 421 is fixedly connected to a first threaded cylinder 416. When the first threaded cylinder 416 slides inside the vertical plate 307, it can drive the connecting column 421 to move back and forth inside the main cylinder 419, thereby driving the piston 420 to reciprocate. The first limiting rod 424 can prevent the first threaded cylinder 416 from rotating with the third threaded rod 417. A second water tank 422 is fixedly installed on the side of the vertical plate 307. The second water tank 422 is connected to the main cylinder 419 via a connecting rod 421. The water pipe is connected to the main cylinder 419. A telescopic hose 423 is fixedly installed at the bottom of the support plate 301. The telescopic hose 423 is connected to the main cylinder 419 through the water pipe. The joints of the telescopic hose 423 and the water pipe are staggered. When the piston 420 moves to the joint of the telescopic hose 423, water from the second water tank 422 can enter the first water tank 311 through the telescopic hose 423, increasing the weight of the first water tank 311. A dustproof mechanism 5 is installed inside the observation window 306. The dustproof mechanism 5 includes a second pulley 501, which is rotatably mounted on the top of the horizontal plate 409. The second pulley 501 is connected to the first pulley 410 through a belt. When the first pulley 410 rotates, it can drive the second pulley 501 to rotate. A vertical cylinder 502 is fixedly installed at the bottom of the horizontal plate 409. A fourth threaded rod 503 is slidably installed inside the vertical cylinder 502. The fourth threaded rod 503 passes through to the top of the vertical cylinder 502 and is threadedly connected to the second pulley 501. A second limiting rod 504 is slidably installed inside the horizontal plate 409. The second limiting rod 504 is fixedly connected to the fourth threaded rod 503. The rotation of the second pulley 501 can drive the fourth threaded rod 503 to move up and down inside the vertical cylinder 502, thereby drawing water from the second water tank 422 into the vertical cylinder 502.

[0033] Reference Figures 1-9Based on the same concept as Embodiment 1 above, this embodiment also proposes that a secondary cylinder 505 is fixedly installed inside the protective cover 302. The secondary cylinder 505 is connected to the vertical cylinder 502 and extends through to the outside of the protective cover 302. Water inside the vertical cylinder 502 can enter the interior of the secondary cylinder 505. A sliding groove 506 is provided on the surface of the protective cover 302. A sliding plate 507 is slidably installed inside the sliding groove 506. A water receiving groove 508 is fixedly installed on the side of the sliding plate 507. Water flowing out of the secondary cylinder 505 can flow into the water receiving groove 508. The weight of the water receiving tank 508 is increased, allowing it to slide inside the sliding groove 506. A connecting rod 509 is fixedly installed on the top of the sliding plate 507, and a second toothed plate 510 is fixedly installed on the top of the connecting rod 509. When the water receiving tank 508 moves up and down, it can drive the connecting rod 509 to move up and down, which in turn can drive the second toothed plate 510 to move up and down. A support 511 is fixedly installed on the side of the protective cover 302, and a toothed rod 512 is rotatably installed inside the support 511. The toothed rod 512 and... The second toothed plate 510 meshes with the toothed rod 512. When the second toothed plate 510 moves up and down, it can drive the toothed rod 512 to rotate inside the support 511. A mounting bracket 513 is slidably mounted on the surface of the connecting rod 509. A third toothed plate 514 is fixedly mounted on the side of the mounting bracket 513. The third toothed plate 514 meshes with the toothed rod 512. The rotation of the toothed rod 512 can drive the third toothed plate 514 to move up and down. A dustproof plate 515 is fixedly mounted on the top of the third toothed plate 514. The dustproof plate 515 extends into the interior of the observation window 306. A water tank 50 is also present. A damping rod 516 is fixedly installed at the bottom of the 8. There are two damping rods 516, and a second spring 517 is sleeved on the surface of the two damping rods 516. The up and down movement of the third toothed plate 514 can drive the dustproof plate 515 to move, so that in windy and rainy weather, the dustproof plate 515 can prevent rainwater and dust from entering the interior of the protective cover 305. The dustproof plate 515 is made of high light transmittance glass, which can not obstruct the view, but also prevent dust from damaging the lens of the surveying instrument 304 and extend the service life of the lens of the surveying instrument 304.

[0034] Reference Figures 1-9Based on the same concept as Embodiment 1 above, this embodiment also proposes that a cleaning mechanism 6 is installed inside the observation window 306. The cleaning mechanism 6 includes a mounting groove 601, which is opened on both sides of the observation window 306. A fifth threaded rod 602 is rotatably installed inside the left mounting groove 601, and a sliding rod 603 is fixedly installed inside the right mounting groove 601. A cleaning plate 604 is threadedly installed on the surface of the fifth threaded rod 602. The cleaning plate 604 is slidably connected to the sliding rod 603. The fifth threaded rod 602 extends to the bottom of the mounting plate 303. A third pulley 605 is fixedly installed at the end of the fifth threaded rod 602. A fourth pulley 606 is rotatably installed at the bottom of the mounting plate 303. The fourth pulley 606 and the third pulley 605 are connected by a belt. The connection is as follows: a second threaded cylinder 607 is fixedly installed at the bottom of the fourth pulley 606. A sixth threaded rod 608 is installed on the internal thread of the second threaded cylinder 607. The sixth threaded rod 608 is fixedly connected to the second threaded rod 408. When the second threaded rod 408 moves up and down, it can drive the sixth threaded rod 608 to move. The up and down movement of the sixth threaded rod 608 can drive the second threaded cylinder 607 to rotate, which can drive the fourth pulley 606 to rotate, which in turn can drive the third pulley 605 to rotate, which in turn can drive the fifth threaded rod 602 to rotate. This allows the cleaning plate 604 to slide on the surface of the dustproof plate 515 to clean the surface of the dustproof plate 515 and prevent dust and rainwater from obstructing the view.

[0035] Specifically, the working process or principle of this vertical surveying instrument for engineering surveying is as follows: First, in windy weather, the wind will cause the anemometer 313 to rotate. The speed of rotation of the anemometer 313 is related to the wind force. The rotation of the anemometer 313 can act on the wind speed sensor 314. The greater the wind speed, the faster the output end of the motor 401 rotates, and vice versa. The motor 401 can drive the rotating shaft 402 to rotate. The rotation of the rotating shaft 402 can drive the actuating lever 403 to rotate. When the actuating lever 403 rotates, it can move the stop lever 406, which in turn can drive the connecting plate 405 and the rotating cylinder 404 to rotate. The rotation of the connecting plate 405 can drive the second threaded rod 408 to slide up and down inside the horizontal plate 409. When the second threaded rod 408 moves up and down, it will also drive the first tooth. The plate 415 moves up and down, and the up and down movement of the first toothed plate 415 can drive the first gear 418 to reciprocate, which in turn can drive the third threaded rod 417 to reciprocate. Therefore, the first threaded cylinder 416 can slide back and forth on the vertical plate 307. When the first threaded cylinder 416 slides inside the vertical plate 307, it can drive the connecting column 421 to move back and forth inside the main cylinder 419, which can drive the piston 420 to reciprocate. When the piston 420 moves to the joint of the telescopic hose 423, the water inside the second water tank 422 can enter the first water tank 311 through the telescopic hose 423, increasing the weight of the first water tank 311. As more and more water is added to the first water tank 311, the position of the first water tank 311 is closer to the bottom, and under the influence of the gravity of the water itself, the center of gravity of the entire device changes.

[0036] The rotation of the second pulley 501 drives the fourth threaded rod 503 to move up and down inside the vertical cylinder 502, thereby drawing water from the second water tank 422 into the vertical cylinder 502. Water flowing out of the auxiliary cylinder 505 flows into the water receiving trough 508, increasing its weight and allowing it to slide within the sliding groove 506. The up-and-down movement of the water receiving trough 508 drives the connecting rod 509 to move up and down, which in turn drives the second toothed plate 510 to move up and down. This movement of the second toothed plate 510 drives the toothed rod 512 to rotate inside the support 511. The rotation of the toothed rod 512 then drives the third toothed plate 514 to move up and down. The up-and-down movement of the third toothed plate 514 can move the dustproof plate 515, allowing rainwater and dust to enter the interior of the protective cover 305 during windy and rainy weather. When the second threaded rod 408 moves up and down, it can move the sixth threaded rod 608. The up-and-down movement of the sixth threaded rod 608 can drive the second threaded cylinder 607 to rotate, which in turn drives the fourth pulley 606 to rotate, which in turn drives the third pulley 605 to rotate, which in turn drives the fifth threaded rod 602 to rotate, allowing the cleaning plate 604 to slide on the surface of the dustproof plate 515 to clean the surface of the dustproof plate 515 and prevent dust and rainwater from obstructing the view.
