Description

Technical Field

[0001] This invention relates to the field of architectural surveying equipment technology, and in particular to an on-site surveying device for architectural design and planning. Background Technology

[0002] In the early design, planning and construction process of building projects, on-site surveying is an indispensable and important procedure. The data collected during the survey, such as site dimensions, elevation differences, building boundaries, and terrain orientation, directly determine the accuracy of subsequent architectural drawings, unit planning, and site layout design.

[0003] Chinese invention patent CN121322799B discloses a design surveying device for building interior decoration, including an annular slide rail. A balance ring is rotatably connected to the inner wall of the annular slide rail. A surveying instrument body is located above the balance ring, and a gravity box is suspended below the balance ring by a chain. The device also includes a main shaft located on the upper surface of the gravity box for driving the surveying instrument body to slide intermittently along the annular slide rail, and a double-layer limiting plate installed at the bottom of the surveying instrument body to control the surveying instrument body to always be on the same horizontal plane at any position on the annular slide rail. A gear assembly is installed inside the gravity box, and a telescopic rod passes through one side of the main shaft. A guide mechanism for connecting the double-layer limiting plate and the telescopic rod is slidably connected to the upper part of the annular slide rail. The gear assembly includes a drive gear and a gear ring meshing with the drive gear. A first motor and a second motor are installed inside the gravity box, and the output shaft of the first motor is fixedly connected to the inner wall of the drive gear.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In the above-mentioned equipment, the first motor drives the active gear to mesh with the gear ring, driving the main shaft to rotate. Then, the power is transmitted through the telescopic rod and the guide mechanism, driving the surveying instrument body to move circumferentially along the annular slide rail, thereby changing different measurement positions. At the same time, the second motor drives the first rotating shaft to rotate, and the power is transmitted sequentially through the universal joint to the telescopic rod, the second rotating shaft and the connecting rod, driving the surveying instrument body to rotate and scan around its own vertical central axis. However, in actual construction site surveying, when facing uneven ground and work areas with large elevation differences, it is impossible to flexibly adjust the tilt angle of the surveying instrument body according to the changes in terrain. It can only maintain a fixed horizontal scanning state, which has weak adaptability to complex terrain conditions and poor measurement adaptability, thus reducing the overall accuracy of surveying. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a field surveying device for architectural design and planning.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a field surveying device for architectural design and planning, comprising a base, a plurality of support rods hinged to the bottom of the base, a rotating disk rotatably mounted on the top of the base, a fixed plate fixed to the top of the rotating disk, two rotating rods rotatably mounted on the outer wall of the fixed plate, the two rotating rods jointly fixing the rotating plate, two driving rods rotatably mounted on the side wall of the rotating plate, the two driving rods jointly fixing a rotating cover, a placement plate fixed to the top of the rotating cover, a surveying instrument body disposed on the top of the placement plate, a driving mechanism for driving the rotating plate or the rotating cover to rotate disposed on the rotating plate, and a control component disposed on the placement plate.

[0007] By adopting the above technical solution, the staff transported the device to the designated surveying location, and then pried open the support rods hinged at the bottom of the base to allow multiple support rods to spread out and support the ground, thus stabilizing the base on the work site and completing the overall support and fixation. The rotating plate drives the fixed plate and the entire surveying structure to rotate horizontally synchronously, adjusting the horizontal orientation of the surveying instrument body. Then, the control component controls the drive mechanism to drive the rotating plate to rotate. The rotating plate drives the drive rod, rotating cover, and placement plate to rotate synchronously, thereby causing the placement plate to tilt the surveying instrument body up and down. Then, the drive mechanism continues to drive the drive rod to rotate, which drives the rotating cover to rotate. The rotating cover causes the placement plate to rotate left and right, thereby causing the placement plate to finely adjust the left and right tilt angle of the surveying instrument body, so as to accurately align with the surveying point. After adjusting the surveying instrument body to the standard surveying angle and orientation, the drive mechanism is turned off to fix the current surveying posture and prevent the surveying instrument body from deviating and shaking during operation. Relying on the multi-angle adjustable structure, data such as the topography, dimensions, and location of the building site are collected on-site. This application changes the traditional technology where the surveying instrument itself cannot flexibly adjust its tilt angle according to changes in terrain, thus ensuring the overall accuracy of the surveying.

[0008] Furthermore, the rotating plate has a through mounting groove, and the driving mechanism includes a transmission assembly. The transmission assembly includes a first fixed rod fixed to the inner wall of the fixed plate, a first conical friction wheel fixedly sleeved on the first fixed rod, a second fixed rod fixed to the inner wall of the mounting groove, a second conical friction wheel rotatably mounted on the second fixed rod and in close contact with the first conical friction wheel, a transmission motor slidably disposed between the inner walls of the mounting groove, and a third conical friction wheel fixedly sleeved on the output shaft of the transmission motor and in close contact with the second conical friction wheel. The driving mechanism also includes a driving component for driving the transmission motor to move.

[0009] Furthermore, the drive assembly includes a connecting plate fixed to the top of the transmission motor and a positioning plate fixed to the top of the rotating plate. Two positioning plates are provided. The drive assembly also includes a positioning rod fixed between the two positioning plates, an electric push rod fixed to the top of the rotating plate and driving the connecting plate to move, and a fourth conical friction wheel fixedly sleeved on the drive rod. One of the two drive rods passes through the rotating plate and extends into the mounting groove. The axis of the fourth conical friction wheel coincides with the axis of the second conical friction wheel.

[0010] By adopting the above technical solution, when the base is stably erected on the work site, the control component controls the electric push rod. The electric push rod starts and pulls the connecting plate fixed on the top of the transmission motor to slide along the positioning rod between the two positioning plates. The connecting plate drives the transmission motor to move closer to the second conical friction wheel. The transmission motor synchronously drives the third conical friction wheel to come into contact with and press against the second conical friction wheel. The control component controls the transmission motor to rotate forward or backward. The transmission motor drives the third conical friction wheel to rotate. The third conical friction wheel drives the second conical friction wheel that is pressed against it to rotate. When the second conical friction wheel rotates around its own axis, it will revolve around the circumference of the first conical friction wheel due to frictional engagement with the stationary first conical friction wheel. This will drive the entire rotating plate to rotate around the axis of the rotating rod. The rotating plate drives the drive rod, the rotating cover and the placement plate to rotate synchronously, so that the placement plate drives the surveying instrument body to tilt up and down. Subsequently, the control component manipulates the electric push rod to move the connecting plate away from the second conical friction wheel. The connecting plate drives the transmission motor to move, and the transmission motor synchronously drives the third and fourth conical friction wheels to come into contact and press against each other. The control component controls the transmission motor to rotate forward or backward, and the transmission motor drives the third conical friction wheel to rotate. The third conical friction wheel drives the fourth conical friction wheel, which is pressed against it, to rotate. The fourth conical friction wheel drives the drive rod to rotate around its own axis (the axis of the drive rod and the axis of the rotating rod are perpendicular to each other). The drive rod drives the rotating cover and the placement plate to deflect left and right around the axis of the drive rod. This allows the placement plate to drive the surveying instrument body to make slight adjustments to the left and right deflection angles, so that it can accurately align with the surveying points.

[0011] Furthermore, an L-shaped abutment plate is fixed to the side of the connecting plate near the fourth conical friction wheel, and the side wall of the L-shaped abutment plate abuts against the side wall of the fourth conical friction wheel.

[0012] By adopting the above technical solution, when the electric push rod drives the transmission motor to make the third conical friction wheel and the second conical friction wheel fully fit together, the transmission motor drives the L-shaped abutment plate to move synchronously, so that the side wall of the L-shaped abutment plate abuts against the side wall of the fourth conical friction wheel. This keeps the fourth conical friction wheel and the drive rod, rotating cover, placement plate and surveying instrument body fixedly connected to it absolutely stationary. They will not deflect left or right with the rotation of the second conical friction wheel, and can only be adjusted up and down tilt angle. When the electric push rod drives the transmission motor to make the third conical friction wheel and the fourth conical friction wheel fully fit together, the transmission motor drives the L-shaped abutment plate to move synchronously, which releases the abutment relationship between the side wall of the L-shaped abutment plate and the side wall of the fourth conical friction wheel.

[0013] Furthermore, the rotating disk is provided with a support assembly for supporting the placement plate. The support assembly is provided in multiple sets. Each set of the support assembly includes a lower U-shaped block slidably disposed on the top of the rotating disk, a sleeve hinged to the lower U-shaped block, a sliding rod slidably disposed inside the sleeve, a spring fixed inside the sleeve, and an upper U-shaped block hinged to the side of the sliding rod away from the sleeve. The rotating disk is provided with a lower arc-shaped groove for the lower U-shaped block to slide, and the side wall of the placement plate is provided with an upper arc-shaped groove for the upper U-shaped block to slide. The two ends of the spring are fixedly connected to the inner wall of the sleeve and the side wall of the sliding rod, respectively.

[0014] By adopting the above technical solution, when the placement plate rotates up and down around the axis of the rotating rod with the rotating plate, the lower U-shaped block slides circumferentially along the lower arc groove on the rotating disk, automatically following the up and down rotation trajectory of the placement plate. The upper U-shaped block slides slightly along the upper arc groove on the side wall of the placement plate. At the same time, the hinge structure between the upper U-shaped block and the sliding rod, and between the lower U-shaped block and the sleeve, automatically adjusts the support angle. The sliding rod slides inside the sleeve, and the spring extends or compresses accordingly, automatically compensating for the change in support length during the up and down rotation. When the placement plate deflects left and right around the axis of the driving rod with the rotating cover, the upper U-shaped block slides circumferentially along the upper arc groove on the side wall of the placement plate, automatically following the left and right deflection trajectory of the placement plate. The lower U-shaped block slides slightly along the lower arc groove on the rotating disk. At the same time, the upper and lower hinge structures automatically adjust the support angle. The sliding rod slides inside the sleeve, and the spring extends or retracts accordingly, automatically compensating for the change in support length during the left and right deflection, maintaining the overall support balance.

[0015] Furthermore, the control components include a tilt sensor disposed on the top of the placement plate and a controller disposed on the top of the placement plate. A power motor for driving the rotating disk is fixed at the bottom of the base. The transmission motor, the power motor, and the electric push rod are all electrically connected to the controller.

[0016] By adopting the above technical solution, the tilt sensor simultaneously and accurately measures the vertical pitch angle (around the axis of the rotating rod) and the horizontal tilt angle (around the axis of the drive rod) of the placement plate. The target horizontal azimuth angle is input, and the controller drives the power motor to rotate the rotating disk. The rotating disk synchronously drives the surveying instrument body to rotate. After the surveying instrument body reaches the target azimuth, it automatically stops and locks. When the tilt sensor detects the vertical pitch angle and horizontal tilt angle deviation of the placement plate, the tilt sensor transmits the detection signal to the controller. The controller controls the electric push rod to move the drive motor in the form of an electrical signal and controls the drive motor to start. Finally, the vertical pitch angle and horizontal tilt angle of the surveying instrument body can be adjusted by the contact and tightness between the third conical friction wheel and the second conical friction wheel, and the contact and tightness between the third conical friction wheel and the fourth conical friction wheel.

[0017] Furthermore, a fixed cover is fixed to the top of the rotating disk, and the inner diameter of the fixed cover is larger than the outer diameter of the rotating cover.

[0018] By adopting the above technical solution, the fixed cover completely covers all transmission components between the rotating disk and the placement plate, preventing sand and gravel from entering the interior of the fixed cover and damaging the transmission components of the drive mechanism, thus ensuring the stability of the transmission.

[0019] Furthermore, the fixing cover has multiple through holes.

[0020] By adopting the above technical solution, multiple evenly distributed through holes form a natural convection heat dissipation channel. External cold air enters through the through holes, and internal hot air is discharged through the through holes, continuously carrying away the heat energy of the internal transmission components of the drive mechanism and ensuring the stability of the transmission.

[0021] Furthermore, the support rod is provided with a placement assembly, and there are multiple sets of placement assemblies, each corresponding to one of the multiple support rods. Each set of placement assemblies includes a U-shaped handle fixed to the side wall of the support rod, an arc-shaped rod fixed to the lower end of the support rod, a conical column fixed to the lower end of the arc-shaped rod, and a foot pedal fixed to the side wall of the arc-shaped rod.

[0022] By adopting the above technical solution, the worker holds the U-shaped handle on the side wall of the support rod. The U-shaped handle drives the support rod to swing outward around the hinge point, completing the unfolding of a single support rod. The worker then steps down on the foot pedal on the side wall of the arc rod, using the weight of the human body to press the conical column vertically into the ground until the lower end of the arc rod is in close contact with the ground, thus completing the fixation of the entire device.

[0023] Furthermore, a support plate for supporting the drive motor is fixed at the bottom of the rotating plate.

[0024] By adopting the above technical solution, the support plate supports the drive motor from the bottom, forming a symmetrical double support system with the top positioning rod, which evenly distributes the weight of the drive motor to the top positioning rod and the bottom support plate, eliminating the sagging deformation of the drive motor caused by its own weight.

[0025] In summary, the present invention has the following beneficial effects: Workers move the device to the designated surveying location, pry open the support rods hinged at the bottom of the base to allow multiple support rods to spread and support the ground, thus stably setting up the base on the work site and completing the overall support and fixation. The control component controls the power motor to drive the top rotating disk to rotate, which in turn drives the fixed plate and the entire surveying structure to rotate horizontally synchronously, adjusting the horizontal orientation of the surveying instrument body. Subsequently, the control component again controls the drive mechanism to drive the rotating rod to rotate around the outer wall of the fixed plate, which in turn drives the rotating plate to rotate. The rotating plate then drives the drive rod, rotating cover, and placement plate to rotate synchronously. The device is flipped so that the placement plate tilts the surveyor body up and down. Then, the drive mechanism drives the drive rod perpendicular to the axis of the rotating rod to rotate. The drive rod drives the rotating cover to rotate, and the rotating cover drives the placement plate to rotate left and right. This allows the placement plate to finely adjust the left and right tilt angle of the surveyor body, so that it can be accurately aligned with the surveying points. After the surveyor body is adjusted to the standard surveying angle and orientation, the drive mechanism is turned off to fix the current surveying posture and prevent the surveyor body from deviating and shaking during operation. Relying on the multi-angle adjustable structure, data such as the topography, dimensions and points of the building site are collected on site. Attached Figure Description

Detailed Implementation

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-9 As shown in the illustration, this application discloses an on-site surveying device for architectural design and planning, comprising a base 1, support rods 11, a rotating disk 12, a fixed plate 14, rotating rods 15, a rotating plate 16, a drive rod 17, a rotating cover 18, a placement plate 19, a surveying instrument body 2, a drive mechanism 3, and a control assembly 4. Multiple support rods 11 are hinged to the bottom of the base 1. The rotating disk 12 is rotatably mounted on the top of the base 1, the fixed plate 14 is fixed to the top of the rotating disk 12, and two rotating rods 15 are rotatably mounted on the outer wall of the fixed plate 14. The rotating rods 15 are arranged in a symmetrical manner. The rotating plate 16 is fixed to the two rotating rods 15, and two drive rods 17 are rotatably mounted on the side wall of the rotating plate 16. The axes of the drive rods 17 and the axes of the rotating rods 15 are perpendicular to each other. The rotating cover 18 is fixed to the two drive rods 17, the placement plate 19 is fixed to the top of the rotating cover 18, and the surveying instrument body 2 is placed on the top of the placement plate 19. The drive mechanism 3 is located in the mounting slot 161. The drive mechanism 3 is used to drive the rotating plate 16 and the drive rod 17 to rotate. The control component 4 is located on the placement plate 19.

[0030] The staff moved the device to the designated surveying location, and pried open the support rods 11 hinged at the bottom of the base 1 to spread them out and support the ground, thus stabilizing the base 1 on the work site and completing the overall support and fixation. The rotating plate 12 drives the fixing plate 14 and the entire surveying structure to rotate horizontally synchronously, adjusting the horizontal orientation of the surveying instrument body 2. Then, the control component 4 controls the drive mechanism 3 to drive the rotating plate 16 to rotate. The rotating plate 16 drives the drive rod 17, the rotating cover 18, and the placement plate 19 to rotate synchronously, thereby causing the placement plate 19 to tilt the surveying instrument body 2 up and down. The angle is then adjusted, and the drive mechanism 3 drives the drive rod 17, which is perpendicular to the axis of the rotating rod 15, to rotate. The drive rod 17 drives the rotating cover 18 to rotate, and the rotating cover 18 drives the placement plate 19 to rotate left and right. This allows the placement plate 19 to drive the surveying instrument body 2 to make slight adjustments to the left and right deflection angles, so as to accurately align with the surveying points. After adjusting the surveying instrument body 2 to the standard surveying angle and orientation, the drive mechanism 3 is turned off to fix the current surveying posture and prevent the surveying instrument body 2 from deviating and shaking during operation. Relying on the multi-angle adjustable structure, data such as the topography, dimensions, and locations of the building site are collected on-site.

[0031] The drive mechanism 3 includes a transmission assembly 31 and a drive assembly 32. The transmission assembly 31 includes a first fixed rod 311, a first conical friction wheel 312, a second fixed rod 313, a second conical friction wheel 314, a drive motor 315, and a third conical friction wheel 316. A mounting groove 161 is provided through the rotating plate 16. The first fixed rod 311 is fixed to the inner wall of the fixed plate 14, and the first conical friction wheel 312 is fixedly sleeved on the first fixed rod 311. The second fixed rod 313 is fixed to the inner wall of the mounting groove 161, and the second conical friction wheel 314 is rotatably mounted on the second fixed rod 313, with the second conical friction wheel 314 and the first conical friction wheel 312 in close contact. The drive motor 315 is slidably disposed between the inner walls of the mounting groove 161, and the third conical friction wheel 316 is fixedly sleeved on the output shaft of the drive motor 315, with the third conical friction wheel 316 in close contact with the second conical friction wheel 314.

[0032] The drive assembly 32 is used to drive the transmission motor 315 to move. The drive assembly 32 includes a connecting plate 321, a positioning plate 322, a positioning rod 323, an electric push rod 324, and a fourth conical friction wheel 325. The connecting plate 321 is fixed to the top of the transmission motor 315, and the positioning plate 322 is fixed to the top of the rotating plate 16. There are two positioning plates 322. The positioning rod 323 is fixed between the two positioning plates 322, and the electric push rod 324 is fixed to the top of the rotating plate 16. The electric push rod 324 drives the connecting plate 321 to move. The fourth conical friction wheel 325 is fixedly sleeved on the drive rod 17. One of the two drive rods 17 passes through the rotating plate 16 and extends into the mounting groove 161. The axis of the fourth conical friction wheel 325 coincides with the axis of the second conical friction wheel 314.

[0033] When the base 1 is stably erected on the work site, the control component 4 controls the electric push rod 324. The electric push rod 324 starts and pulls the connecting plate 321 fixed to the top of the drive motor 315 to slide along the positioning rod 323 between the two positioning plates 322. The connecting plate 321 drives the drive motor 315 to move closer to the second conical friction wheel 314. The drive motor 315 simultaneously drives the third conical friction wheel 316 to come into contact with and press against the second conical friction wheel 314. The control component 4 controls the drive motor 315 to rotate forward or backward. The third conical friction wheel 316 is driven to rotate, and the third conical friction wheel 316 drives the second conical friction wheel 314, which is pressed against it, to rotate. When the second conical friction wheel 314 rotates around its own axis, it will revolve around the circumference of the first conical friction wheel 312 due to frictional engagement with the stationary first conical friction wheel 312. This will drive the entire rotating plate 16 to rotate around the axis of the rotating rod 15. The rotating plate 16 drives the drive rod 17, the rotating cover 18 and the placement plate 19 to rotate synchronously, so that the placement plate 19 drives the surveying instrument body 2 to tilt up and down. Subsequently, the control component 4 manipulates the electric push rod 324 to push the connecting plate 321 away from the second conical friction wheel 314. The connecting plate 321 drives the transmission motor 315 to move. The transmission motor 315 simultaneously drives the third conical friction wheel 316 to come into contact with and press against the fourth conical friction wheel 325. The control component 4 controls the transmission motor 315 to rotate forward or backward. The transmission motor 315 drives the third conical friction wheel 316 to rotate. The third conical friction wheel 316 drives the fourth conical friction wheel 325, which is pressed against it, to rotate. The fourth conical friction wheel 325 drives the drive rod 17 to rotate around its own axis (the axis of the drive rod 17 is perpendicular to the axis of the rotating rod 15). The drive rod 17 drives the rotating cover 18 and the placement plate 19 to deflect left and right around the axis of the drive rod 17. This allows the placement plate 19 to drive the surveying instrument body 2 to finely adjust the left and right deflection angle, so as to accurately align with the surveying point.

[0034] The control component 4 includes a tilt sensor 41 and a controller 42. The tilt sensor 41 is located on the top of the placement plate 19, and the controller 42 is located on the top of the placement plate 19. A power motor 13 is fixed to the bottom of the base 1. The power motor 13 is used to drive the rotating disk 12 to rotate. The transmission motor 315, the power motor 13, and the electric push rod 324 are all electrically connected to the controller 42.

[0035] The tilt sensor 41 simultaneously and accurately measures the vertical pitch angle (around the axis of the rotating rod 15) and the horizontal tilt angle (around the axis of the drive rod 17) of the placement plate 19. The target horizontal azimuth angle is input, and the controller 42 drives the power motor 13 to rotate the rotating disk 12. The rotating disk 12 synchronously drives the surveying instrument body 2 to rotate. After the surveying instrument body 2 reaches the target azimuth, it automatically stops and locks. When the tilt sensor 41 detects the vertical pitch angle and the horizontal tilt angle deviation of the placement plate 19, the tilt sensor 41 transmits the detection signal to the controller 42. The controller 42 controls the electric push rod 324 to move the drive motor 315 in the form of an electrical signal and controls the drive motor 315 to start. Finally, the vertical pitch angle and the horizontal tilt angle of the surveying instrument body 2 can be adjusted by the contact and tightness between the third conical friction wheel 316 and the second conical friction wheel 314 and the third conical friction wheel 316 and the fourth conical friction wheel 325.

[0036] In this embodiment, an L-shaped abutment plate 5 is fixed on the side of the connecting plate 321 near the fourth conical friction wheel 325, and the side wall of the L-shaped abutment plate 5 abuts against the side wall of the fourth conical friction wheel 325. When the electric push rod 324 drives the transmission motor 315 to make the third conical friction wheel 316 and the second conical friction wheel 314 fully fit together, the transmission motor 315 drives the L-shaped abutment plate 5 to move synchronously, so that the side wall of the L-shaped abutment plate 5 abuts against the side wall of the fourth conical friction wheel 325. This keeps the fourth conical friction wheel 325 and the drive rod 17, rotating cover 18, placement plate 19 and surveying instrument body 2 fixedly connected to it absolutely stationary. They will not deflect left or right with the rotation of the second conical friction wheel 314. They can only adjust the pitch angle. When the electric push rod 324 drives the transmission motor 315 to make the third conical friction wheel 316 and the fourth conical friction wheel 325 fully fit together, the transmission motor 315 drives the L-shaped abutment plate 5 to move synchronously, which releases the abutment relationship between the side wall of the L-shaped abutment plate 5 and the side wall of the fourth conical friction wheel 325.

[0037] In this embodiment, a support assembly 6 is provided on the rotating disk 12 to support the placement plate 19. Multiple sets of support assemblies 6 are provided, each set including a lower U-shaped block 61, a sleeve 62, a sliding rod 63, a spring 64, and an upper U-shaped block 65. The lower U-shaped block 61 is slidably disposed on the top of the rotating disk 12, and the sleeve 62 is hinged to the lower U-shaped block 61. The sliding rod 63 is slidably disposed inside the sleeve 62, and the spring 64 is fixed inside the sleeve 62. Both ends of the spring 64 are fixedly connected to the inner wall of the sleeve 62 and the side wall of the sliding rod 63, respectively. The upper U-shaped block 65 is hinged to the side of the sliding rod 63 away from the sleeve 62. A lower arc-shaped groove 121 is provided on the rotating disk 12 for the lower U-shaped block 61 to slide. An upper arc-shaped groove 191 is provided on the side wall of the placement plate 19 for the upper U-shaped block 65 to slide.

[0038] When the placement plate 19 tilts up and down with the rotating plate 16 around the axis of the rotating rod 15, the lower U-shaped block 61 slides circumferentially along the lower arc groove 121 on the rotating disk 12, automatically following the tilting trajectory of the placement plate 19. The upper U-shaped block 65 slides slightly along the upper arc groove 191 on the side wall of the placement plate 19. At the same time, the hinge structure between the upper U-shaped block 65 and the slide rod 63, and between the lower U-shaped block 61 and the sleeve 62, automatically adjusts the support angle. The slide rod 63 slides inside the sleeve 62, and the spring 64 extends or compresses accordingly, automatically compensating for the change in support length during the tilting rotation. When the placement plate 19 rotates left and right around the axis of the drive rod 17 with the rotating cover 18, the upper U-shaped block 65 slides circumferentially along the upper arc groove 191 on the side wall of the placement plate 19, automatically following the left and right lateral rotation trajectory of the placement plate 19. The lower U-shaped block 61 slides slightly along the lower arc groove 121 on the rotating disk 12. At the same time, the upper and lower hinge structures automatically adjust the support angle, the slide rod 63 slides inside the sleeve 62, and the spring 64 extends and retracts accordingly, automatically compensating for the change in support length during the left and right lateral rotation, and maintaining the overall support balance.

[0039] In this embodiment, a fixed cover 7 is fixed to the top of the rotating disk 12, and the inner diameter of the fixed cover 7 is larger than the outer diameter of the rotating cover 18. The fixed cover 7 completely covers all transmission components between the rotating disk 12 and the placement plate 19, preventing sand and gravel from entering the interior of the fixed cover 7 and damaging the transmission components of the drive mechanism 3, thus ensuring the stability of the transmission.

[0040] In this embodiment, a through hole 71 is provided through the fixed cover 7, and multiple through holes 71 are provided. Multiple evenly distributed through holes 71 form a natural convection heat dissipation channel. External cold air enters through the through holes 71, and internal hot air is discharged through the through holes 71, continuously carrying away the heat energy of the internal transmission components of the drive mechanism 3, ensuring the stability of the transmission.

[0041] In this embodiment, a placement assembly 8 is provided on the support rod 11. Multiple placement assemblies 8 are provided, each corresponding to one of the support rods 11. Each placement assembly 8 includes a U-shaped handle 81, an arc-shaped rod 82, a conical column 83, and a foot pedal 84. The U-shaped handle 81 is fixed to the side wall of the support rod 11, and the arc-shaped rod 82 is fixed to the lower end of the support rod 11. The conical column 83 is fixed to the lower end of the arc-shaped rod 82, and the foot pedal 84 is fixed to the side wall of the arc-shaped rod 82. The operator holds the U-shaped handle 81 on the side wall of the support rod 11, causing the support rod 11 to swing outwards around the hinge point, thus unfolding a single support rod 11. The operator then steps on the foot pedal 84 on the side wall of the arc-shaped rod 82, using their own weight to press the conical column 83 vertically into the ground until the lower end of the arc-shaped rod 82 is in close contact with the ground, thus securing the entire device.

[0042] In this embodiment, a support plate 9 is fixed to the bottom of the rotating plate 16. The support plate 9 is used to support the drive motor 315. The support plate 9 supports the drive motor 315 from the bottom and forms a symmetrical double support system with the top positioning rod 323. This system evenly distributes the weight of the drive motor 315 onto the top positioning rod 323 and the bottom support plate 9, eliminating the sagging deformation of the drive motor 315 caused by its own weight.
