Description

Technical Field

[0001] This invention relates to the technical field of measuring equipment, and more particularly to a fixed-point surveying tool for architectural design and planning. Background Technology

[0002] Measuring equipment refers to devices used to measure various dimensions of buildings. Surveying instruments are a common type of measuring equipment, widely used in architectural design due to their high measurement precision. However, current surveying devices are susceptible to dust and moisture during the surveying process. Existing tools lack dustproof and waterproof designs, requiring manual wiping during surveying, reducing ease of use. Furthermore, workers must manually open and close the support frame to adjust support and height, which reduces efficiency. After surveying, the support frame needs to be secured again, which not only locks it in place but also prevents timely surveying, further reducing efficiency. Summary of the Invention

[0026] Reference Figures 1-5 The first embodiment of the present invention provides a surveying mechanism 100 and a shrinking mechanism 200, which facilitates the unfolding during surveying and the shrinking and transportation after surveying.

[0027] The surveying mechanism 100 includes a surveying platform 101. The bottom of the surveying platform 101 is movably connected to a support leg 102, and three support legs 102 are provided. A laser rangefinder 103 is fixedly connected to the top of the surveying platform 101. A reinforcing plate 104 is fixedly connected to the left side of the laser rangefinder 103. Three reinforcing plates 104 are provided and are evenly distributed. The bottom of the reinforcing plate 104 is fixedly connected to the left side of the top of the surveying platform 101.

[0028] The retraction mechanism 200 includes a motor 201. The top of the motor 201 is fixedly connected to the bottom of the surveying platform 101. A screw 202 is fixedly connected to the output end of the motor 201. A screw sleeve 203 is threadedly connected to the top surface of the screw 202. A first telescopic sleeve 204 is fixedly connected to the surface of the screw sleeve 203. Three first telescopic sleeves 204 are arranged in a ring and evenly distributed. A second telescopic sleeve 205 is slidably connected inside the first telescopic sleeve 204. A telescopic rod 206 is slidably connected inside the second telescopic sleeve 205. Springs 207 are fixedly connected to the left side of the telescopic rod 206 and the left side of the second telescopic sleeve 205. The right side of the telescopic rod 206 is movably connected to the inner side of the support leg 102. A limit groove 208 is opened on the inner side of the support leg 102. A limit block 209 is slidably connected inside the limit groove 208. The inner side of the limit block 209 is fixedly connected to the outer side of the telescopic rod 206.

[0029] Specifically, after reaching the designated surveying position, motor 201 drives the support leg 102 to move outwards downwards, ensuring that the support leg 102 opens outwards to a suitable angle with its connection point with the surveying platform 101 as the fulcrum, until the bottom of the support leg 102 is in close contact with the ground, forming a stable triangular support structure. This process eliminates the need for manual prying of the support leg 102, significantly improving support adjustment efficiency. Furthermore, the triangular support structure ensures stability during the surveying process, preventing instability from affecting surveying accuracy. Once the support leg 102 is stably deployed, the laser rangefinder 103 begins construction. In the fixed-point surveying work of architectural design and planning, the laser rangefinder 103 accurately measures the distance, position and other parameters of the designated point by emitting laser. After the fixed-point surveying work is completed, the tool needs to be retracted and transported. At this time, the motor 201 is started again, driving the support legs 102 to move inward until the three support legs 102 are retracted and attached to the bottom of the surveying table 101. At this time, the motor 201 is stopped, and the retraction of the support legs 102 is completed. There is no need to manually tie the support legs 102. The operation is simple and can be completed quickly, which is convenient for timely transport to the next surveying point and improves surveying efficiency.

[0030] Furthermore, upon reaching the designated surveying position, the motor 201 in the retraction mechanism 200 is activated. The output of the motor 201 drives the screw 202 to rotate counterclockwise (the screw sleeve 203 is initially positioned above the screw 202). Under the action of the rotation of the screw 202, the screw sleeve 203, initially positioned above, moves downward along the screw 202, thereby driving the three annularly distributed first telescopic sleeves 204 to move downward synchronously (the screw sleeve 203 is fixedly connected to the three first telescopic sleeves 204, and the screw 202 and the screw sleeve 203 are threaded together). (Connection to ensure synchronized movement) When the first telescopic sleeve 204 moves downward, the second telescopic sleeve 205 inside it extends outward under the elastic force of the spring 207. During the extension of the second telescopic sleeve 205, the telescopic rod 206 inside it also extends further outward under the elastic force of the spring 207. The right side of the telescopic rod 206 is movably connected to the inner side of the support leg 102, and the limiting block 209 on the outer side of the telescopic rod 206 slides in the limiting groove 208 on the inner side of the support leg 102, playing a limiting and guiding role to prevent the telescopic rod 206 from sliding outward. As the telescopic rod 206 extends, it pushes the support leg 102 downwards and outwards, ensuring that the support leg 102 opens outwards to a suitable angle with its connection point with the surveying platform 101 as the fulcrum, until the bottom of the support leg 102 is in close contact with the ground, forming a stable triangular support structure. At this point, the motor 201 stops operating, and the surveying platform 101 remains horizontal, providing stable support for subsequent surveying work. This process eliminates the need for manual prying apart of the support leg 102, significantly improving support adjustment efficiency, and the triangular support structure... To ensure stability during the surveying process and avoid affecting surveying accuracy due to unstable support, after the support leg 102 is deployed and stabilized, the laser rangefinder 103 begins to perform fixed-point surveying work for architectural design planning. The laser rangefinder 103 accurately measures parameters such as distance and position of designated points by emitting lasers. The three equally spaced reinforcing plates 104 on its left side further enhance the connection stability between the laser rangefinder 103 and the surveying platform 101, preventing the laser rangefinder 103 from shaking during the surveying process and ensuring the accuracy of the surveying data.

[0031] After the fixed-point surveying work is completed, the tools need to be retracted and moved. At this time, the motor 201 is restarted, and the output end of the motor 201 drives the screw 202 to rotate counterclockwise. The rotation of the screw 202 drives the screw sleeve 203 to move downward along the screw 202. The screw sleeve 203 drives the three first telescopic sleeves 204 to move downward synchronously. When the first telescopic sleeves 204 move downward, they apply an inward pulling force to the second telescopic sleeves 205, overcoming the elastic force of the spring 207, so that the second telescopic sleeves 205 retract to the first telescopic sleeves 204. Inside, the second telescopic sleeve 205 simultaneously applies an inward pulling force to the telescopic rod 206, causing the telescopic rod 206 to retract into the second telescopic sleeve 205. During the retraction of the telescopic rod 206, it drives the support legs 102 to close inward until the three support legs 102 retract to fit against the bottom of the surveying platform 101. At this point, the motor 201 stops running, completing the retraction of the support legs 102. There is no need for manual binding of the support legs 102, making the operation simple and quick. This facilitates timely transport to the next surveying point and improves surveying efficiency. Example 2

[0032] Reference Figures 1-5 In the second embodiment of the present invention, a protective mechanism 300 is provided to protect and clean the detection area and provide sunshade during use.

[0033] The protective mechanism 300 includes a cover assembly 301, a sunshade assembly 302, and a cleaning assembly 303. The cover assembly 301 includes an upper cover 301a, the left side of which is fixedly connected to the top right side of the laser rangefinder 103. A lower cover 301b is provided at the bottom of the upper cover 301a, and a transmission rod 301c is fixedly connected to the bottom of the lower cover 301b. A movable groove 301d is provided on the right side of the top of the surveying platform 101. The bottom of the transmission rod 301c is fixedly connected to the top of the right-side first telescopic sleeve 204 through the movable groove 301d. The sunshade assembly 302 includes a sunshade half... A lifting rod 302b is fixedly connected to the right side of the lower cover 301b, and the top of the lifting rod 302b contacts the top of the inner wall of the sunshade half-cover 302a. Limiting sleeves 302c are fixedly connected to both the front and back of the sunshade half-cover 302a. A support plate 302d is provided at the bottom of the limiting sleeve 302c. The left side of the support plate 302d is fixedly connected to the right side of the laser rangefinder 103. A limiting rod 302e is connected to the top of the support plate 302d. The top of the limiting rod 302e extends through to the top of the limiting sleeve 302c and slides in connection with the limiting sleeve 302c, thus limiting the movement of the sunshade half-cover 302a. A limiting disc 302f is fixedly connected to the top of rod 302e. The diameter of the limiting disc 302f is larger than the diameter of the inner wall of the limiting sleeve 302c. A tension spring 302g is fixedly connected to the bottom of the limiting sleeve 302c. The other end of the tension spring 302g is fixedly connected to the top of the support plate 302d. The tension spring 302g is sleeved on the surface of the limiting rod 302e. The cleaning component 303 includes an airbag 303a. The bottom of the airbag 303a is fixedly connected to the top of the sunshade half-sleeve 302a. A mounting plate 303b is fixedly connected to the top of the airbag 303a. The mounting plate 303b is connected to the laser rangefinder 1. 03 Fixed connection, the upper cover 301a is hollow and the inner wall of the upper cover 301a has an exhaust hole 303c. The right side of the inner wall of the lower cover 301b is fixedly connected to a wiping cotton 303d. The bottom of the airbag 303a is connected to a hose 303e. The other end of the hose 303e is connected to an exhaust one-way valve 303f. The exhaust one-way valve 303f is connected to the lower cover 301b. The top of the mounting plate 303b is fixedly connected to an air intake one-way valve 303g. Several air intake one-way valves 303g are provided and are evenly distributed. The air intake one-way valves 303g are connected to the airbag 303a.

[0034] Specifically, when the screw sleeve 203 moves downward driven by the screw 202, the sunshade half-sleeve 302a moves to a suitable lower position. At this time, the sunshade half-sleeve 302a has a sunshade effect, providing sun protection for the detection end of the laser rangefinder 103, preventing direct sunlight from hitting the laser detection end and causing a decrease in mapping accuracy, ensuring that mapping work can be carried out normally under different lighting conditions. At the same time, the airbag 303a returns to its natural inflated state. During the retraction of the support leg 102, the first telescopic sleeve 204 moves downward, driving the transmission rod 301c to move downward synchronously. The transmission rod 301c drives the lower cover 301b to move downward. When the lower cover 301b moves downward, the pushing force of the lifting rod 302b on the sunshade half-sleeve 302a gradually decreases. Under the tension of the tension spring 302g, the sunshade half-sleeve 302a moves downward along the limiting rod 302e until it returns to the initial low position (i.e., the upper position that was lifted up), canceling the sunshade effect. As the sunshade half-cover 302a moves downwards, the pressure on the airbag 303a disappears, and the airbag 303a expands under its own elasticity. At this time, the intake one-way valve 303g opens and the exhaust one-way valve 303f closes, allowing outside air to enter the airbag 303a through the intake one-way valve 303g, causing the airbag 303a to return to its natural expanded state, preparing it for the next cleaning operation. As the lower cover 301b moves downwards, the wiping cotton 303d on its inner wall contacts and slides against the detection end of the laser rangefinder 103 again, performing a secondary wiping and cleaning. At the same time, the lower cover 301b and the upper cover 301a work together to form a complete protective enclosure for the detection end of the laser rangefinder 103, preventing dust, moisture, and other impurities from contaminating the detection end during transportation. It also prevents the detection end from being damaged by collisions during transportation, providing good protection and ensuring the tool's service life and the accuracy of the next survey.

[0035] Furthermore, as the screw sleeve 203 moves downward under the drive of the screw 202, the lower cover 301b moves downward under the action of the first telescopic sleeve 204. Simultaneously, the lifting rod 302b on the right side of the lower cover 301b moves downward. The pushing force of the lifting rod 302b on the sunshade half-sleeve 302a gradually decreases. Under the tension of the tension spring 302g, the sunshade half-sleeve 302a moves downward along the limiting rod 302e. The limiting sleeves 302c on both sides of the sunshade half-sleeve 302a slide downward simultaneously along the limiting rod 302e. The limiting plate at the top of the limiting rod 302e... 302f prevents the limiting sleeve 302c from falling off the top of the limiting rod 302e, thus acting as a limiter until the sunshade half-sleeve 302a moves to the appropriate lower position. At this point, the sunshade half-sleeve 302a provides sunshade protection for the detection end of the laser rangefinder 103, preventing direct sunlight from affecting the laser detection end and causing a decrease in surveying accuracy. This ensures that surveying work can be carried out normally under different lighting conditions. During the surveying process, if the detection end of the laser rangefinder 103 becomes contaminated with dust, moisture, or other impurities, the cleaning component 303 can simultaneously perform cleaning operations. When the screw sleeve 203 resets (equivalent to retracting the support leg 102), the sunshade half-sleeve 302a will be lifted upward by the lifting rod 302b, and its top will contact the bottom of the airbag 303a and apply an upward compressive force to the airbag 303a. After the airbag 303a is compressed, the gas inside is compressed. Since the exhaust one-way valve 303f is open and the intake one-way valve 303g is closed, the compressed gas in the airbag 303a enters the exhaust one-way valve 303f through the hose 303e, and is then transported to the interior of the lower cover 301b by the exhaust one-way valve 303f. The gas inside the lower cover 301b is discharged through the exhaust hole 303c on the inner wall of the upper cover 301a. The discharged gas can clean the detection end of the laser rangefinder 103 by blowing air, removing dust and impurities from the surface. At the same time, as the lower cover 301b moves upward, the wiping cotton 303d on the right side of its inner wall contacts and slides relative to the surface of the detection end of the laser rangefinder 103, further wiping and cleaning the detection end to ensure its cleanliness, avoid impurities from affecting laser transmission, and ensure mapping accuracy. No manual wiping is required, which improves the ease of use.

[0036] During the retraction of the support leg 102, the first telescopic sleeve 204 moves downward, causing the transmission rod 301c to move downward synchronously. The transmission rod 301c causes the lower cover 301b to move downward. As the lower cover 301b moves downward, the pushing force of the lifting rod 302b on the sunshade half-sleeve 302a gradually decreases. Under the tension of the tension spring 302g, the sunshade half-sleeve 302a moves downward along the limiting rod 302e until it returns to its initial low position (i.e., the upper position that was lifted up, thus canceling the sunshade effect). At the same time, as the sunshade half-sleeve 302a moves downward, the squeezing force on the airbag 303a disappears, and the airbag 303a expands under its own elasticity. At this time, the intake one-way valve 303g opens, and the exhaust one-way valve opens. When valve 303f is closed, outside air enters the airbag 303a through the one-way air inlet valve 303g, causing the airbag 303a to return to its natural inflated state, preparing it for the next cleaning operation. As the lower cover 301b moves downward, the wiping cotton 303d on its inner wall comes into contact with the detection end of the laser rangefinder 103 again and slides to perform a secondary wiping and cleaning. At the same time, the lower cover 301b and the upper cover 301a work together to form a complete protective enclosure for the detection end of the laser rangefinder 103, preventing dust, moisture and other impurities from contaminating the detection end during transportation. It also prevents the detection end from being damaged by collisions during transportation, providing good protection and ensuring the service life of the tool and the accuracy of the next survey.

[0037] The remaining structure is the same as that in Example 1. Example 3

[0038] Reference Figures 1-5 This is the third embodiment of the present invention, which differs from the second embodiment in that it provides a fixed-point surveying tool for architectural design and planning.

[0039] The surveying tool is moved to the designated surveying location required for architectural design and planning. At this time, the support leg 102 is in a retracted and closed state, which is convenient for handling and moving, avoiding the problem of the traditional surveying tool support leg 102 being scattered and difficult to move. At the same time, the lower cover 301b in the protective mechanism 300 is in a retracted state, and the sunshade half-set 302a is in a lifted state (in the upper position, canceling the sunshade effect), which does not affect the surveying field of the laser rangefinder 103. The wiping cotton 303d does not contact the detection end of the laser rangefinder 103, the airbag 303a is in a naturally inflated state, the air intake one-way valve 303g remains open, and the exhaust one-way valve 303f remains closed, ensuring that the airbag 303a can take in air normally. Only when the surveying work begins will the sunshade half-set 302a descend to the lower position to exert the sunshade effect and prepare for the surveying work.

[0040] Upon reaching the designated surveying position, the motor 201 in the retraction mechanism 200 is activated. The output of the motor 201 drives the screw 202 to rotate counterclockwise (the screw sleeve 203 is initially positioned above the screw 202). Under the rotation of the screw 202, the screw sleeve 203, initially positioned above, moves downward along the screw 202, thereby causing the three annularly distributed first telescopic sleeves 204 to move downward synchronously (the screw sleeve 203 is fixedly connected to the three first telescopic sleeves 204, and the screw 202 is threadedly connected to the screw sleeve 203 to ensure synchronous movement). When the first telescopic sleeve 204 moves downward, the second telescopic sleeve 205 inside it extends outward under the elastic force of the spring 207. During the extension of the second telescopic sleeve 205, the telescopic rod 206 inside it also extends further outward under the elastic force of the spring 207. The right side of the telescopic rod 206 is movably connected to the inner side of the support leg 102, and the limiting block 209 on the outer side of the telescopic rod 206 slides in the limiting groove 208 on the inner side of the support leg 102, which plays a limiting and guiding role to prevent the telescopic rod 206 from deviating. As the telescopic rod 206 extends, it pushes the support leg 102 downward to move outward, ensuring that the support leg 102 opens outward to a suitable unfolding angle with the connection point with the surveying table 101 as the fulcrum, until the bottom of the support leg 102 is in close contact with the ground, forming a stable triangular support structure. At this time, the motor 201 stops running, and the surveying table 101 remains in a horizontal state, providing stable support for subsequent surveying work. This process does not require manual prying of the support leg 102, which greatly improves the efficiency of support adjustment, and the triangular support structure ensures the stability during the surveying process, avoiding the impact of unstable support on the surveying accuracy.

[0041] After the support leg 102 is deployed and stabilized, the laser rangefinder 103 begins to perform fixed-point surveying work for architectural design planning. The laser rangefinder 103 accurately measures parameters such as distance and position of designated points by emitting lasers. The three equally spaced reinforcing plates 104 on its left side further enhance the connection stability between the laser rangefinder 103 and the surveying platform 101, preventing the laser rangefinder 103 from shaking during the surveying process and ensuring the accuracy of the surveying data.

[0042] When the screw sleeve 203 moves downward under the drive of the screw 202, as the lower cover 301b moves downward under the action of the first telescopic sleeve 204, the lifting rod 302b on the right side of the lower cover 301b moves downward synchronously. The pushing force of the lifting rod 302b on the sunshade half-sleeve 302a gradually decreases. Under the tension of the tension spring 302g, the sunshade half-sleeve 302a moves downward along the limiting rod 302e. The limiting sleeves 302c on both sides of the sunshade half-sleeve 302a slide downward synchronously along the limiting rod 302e. The limiting plate 302 at the top of the limiting rod 302e... f can prevent the limiting sleeve 302c from falling off the top of the limiting rod 302e, thus playing a limiting role until the sunshade half sleeve 302a moves to the appropriate position below. At this time, the sunshade half sleeve 302a has a sunshade effect, providing sun protection for the detection end of the laser rangefinder 103, avoiding direct sunlight on the laser detection end and causing a decrease in mapping accuracy, ensuring that the mapping work can be carried out normally under different lighting conditions. During the mapping process, if the detection end of the laser rangefinder 103 becomes contaminated with dust, water vapor, or other impurities, the cleaning component 303 can simultaneously perform cleaning operations. When 203 is reset (equivalent to retracting the support leg 102), the sunshade half-cover 302a will be lifted upward by the lifting rod 302b, and its top will contact the bottom of the airbag 303a and apply an upward compressive force to the airbag 303a. After the airbag 303a is compressed, the gas inside is compressed. Due to the opening of the exhaust one-way valve 303f and the closing of the intake one-way valve 303g, the compressed gas in the airbag 303a enters the exhaust one-way valve 303f through the hose 303e, and is then transported to the interior of the lower cover 301b by the exhaust one-way valve 303f. The gas inside the cover 301b is discharged through the exhaust hole 303c on the inner wall of the upper cover 301a. The discharged gas can clean the detection end of the laser rangefinder 103 by blowing air, removing dust and impurities from the surface. At the same time, as the lower cover 301b moves upward, the wiping cotton 303d on the right side of its inner wall contacts and slides relative to the surface of the detection end of the laser rangefinder 103, further wiping and cleaning the detection end to ensure its cleanliness, avoid impurities from affecting laser transmission, and ensure mapping accuracy. No manual wiping is required, which improves the ease of use.

[0043] After the fixed-point surveying work is completed, the tools need to be retracted and moved. At this time, the motor 201 is restarted, and the output end of the motor 201 drives the screw 202 to rotate counterclockwise. The rotation of the screw 202 causes the screw sleeve 203 to move downward along the screw 202. The screw sleeve 203 drives the three first telescopic sleeves 204 to move downward synchronously. When the first telescopic sleeves 204 move downward, they apply an inward pulling force to the second telescopic sleeves 205, overcoming the elastic force of the spring 207, causing the second telescopic sleeves 205 to retract into the first telescopic sleeves 204. At the same time, the second telescopic sleeves 205 apply an inward pulling force to the telescopic rod 206, making... The telescopic rod 206 retracts into the second telescopic sleeve 205. During the retraction of the telescopic rod 206, it drives the support legs 102 to move inward until all three support legs 102 are retracted and flush with the bottom of the surveying platform 101. At this point, the motor 201 stops running, completing the retraction of the support legs 102. No manual binding of the support legs 102 is required; the operation is simple and quick, facilitating timely transport to the next surveying point and improving surveying efficiency. During the retraction of the support legs 102, the first telescopic sleeve 204 moves downward, causing the transmission rod 301c to move downward synchronously. The transmission rod 301c drives the lower cover 301b to move... As the lower cover 301b moves downward, the pushing force of the lifting rod 302b on the sunshade half-sleeve 302a gradually decreases. Under the tension of the tension spring 302g, the sunshade half-sleeve 302a moves downward along the limiting rod 302e until it returns to its initial low position (i.e., the lifted upper position, canceling the sunshade effect). At the same time, as the sunshade half-sleeve 302a moves downward, the compressive force on the airbag 303a disappears, and the airbag 303a inflates under its own elasticity. At this time, the intake one-way valve 303g opens and the exhaust one-way valve 303f closes, allowing outside air to enter the airbag 302a through the intake one-way valve 303g. Inside 3a, the airbag 303a returns to its natural inflated state, preparing for the next cleaning operation. As the lower cover 301b moves downward, the wiping cotton 303d on its inner wall comes into contact with the detection end of the laser rangefinder 103 again and slides to perform a second wiping and cleaning. At the same time, the lower cover 301b and the upper cover 301a work together to form a complete protective enclosure for the detection end of the laser rangefinder 103, preventing dust, moisture and other impurities from contaminating the detection end during transportation. It can also prevent the detection end from being damaged by collisions during transportation, playing a good protective role and ensuring the service life of the tool and the accuracy of the next survey.

[0044] In summary, when using the surveying agency 100 for surveying, the support of the surveying agency 100 is retracted by the retraction mechanism 200 upon completion of the survey, thus eliminating the need for binding and facilitating timely transportation. After the retraction mechanism 200 completes its retraction, it will also drive the protective mechanism 300 to provide a protective cover, and the inspection area can also be cleaned at the same time.
