Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping engineering technology, and in particular to an automatically rotating prism base. Background Technology

[0002] In the field of surveying and mapping engineering, accurately acquiring the angle, distance, and coordinate information of spatial points is a core requirement for scenarios such as topographic mapping, infrastructure construction, and geological disaster monitoring. Prisms, as key optical reflectors, work in conjunction with observation equipment such as total stations to form the basic technical framework for surveying operations. In actual operations, the total station plays a crucial role in data acquisition and control, emitting a detection signal of a specific wavelength (such as the commonly used red laser) towards the target direction. The prism, on its base, is stably mounted at the preset observation point to reflect the laser signal back to the total station. After receiving the reflected signal, the total station, combined with calculations from its internal distance and angle measurement modules, can quickly calculate key parameters such as the distance between the observation point and the station, the horizontal angle, and the vertical angle, ultimately generating surveying data that meets the required accuracy.

[0003] In actual surveying operations, especially in typical scenarios such as full-circle observation and simultaneous monitoring of multiple target points, it is often necessary to conduct sequential or cyclic observations of multiple discrete points around the same station to construct a complete spatial data network. However, the traditional prism bases commonly used in the industry today focus only on basic fixing and leveling functions. They typically consist of a base, leveling screws, and prism connectors, lacking automated components to drive the prisms for orientation adjustment. This means that prism alignment at each observation point requires manual intervention. Consequently, dedicated personnel must be stationed at each observation point in advance. After the total station is switched to the target point, the personnel must manually rotate the prism connectors, visually compare the laser landing point with the total station, and repeatedly adjust the prism orientation until the total station receives a stable reflected signal. This manual adjustment method not only significantly increases labor costs but also affects observation efficiency. Utility Model Content

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-3As shown, this utility model provides an automatically rotating prism base, including a base 5, a rotating seat 1, a rotation drive unit 4, and a lifting drive unit 6. The rotating seat 1 includes a circular seat body 11 and a prism mounting bracket 12 disposed on the circular seat body 11. A rotating disk 2 is fixedly mounted on the bottom of the circular seat body 11. The rotating disk 2 is provided with a toothed groove 21 along its circumference. A mounting disk 3 is provided on the bottom of the rotating disk 2. The rotating disk 2 is rotatably mounted on the mounting disk 3. The rotation drive unit 4 is disposed on the mounting disk 3. The rotating disk 2 is connected to the rotation drive unit 4 through a transmission. The rotating disk 2 is driven by the rotation drive unit 4 and can rotate on the mounting disk 3. A control unit 13 is disposed on the circular seat body 11. The control unit 13 is connected to the rotation drive unit 4 through a transmission.

[0024] Specifically, the base 5 is used for mounting the rotating seat 1 and the lifting drive unit 6. An adjustable leveling screw is provided at the bottom of the base 5, and a small bubble level is embedded in the top edge of the circular seat 11 to assist in calibrating the horizontal state of the rotating seat 1. The leveling screw and the small bubble level are common structures in the prior art and will not be described in detail. The rotating seat 1 includes a circular seat 11 and a prism mounting bracket 12. The size of the circular seat 11 is smaller than that of the base 5. The circular seat 11 is made of lightweight magnesium alloy to reduce the rotational load. The prism mounting bracket 12 is vertically fixed to the center of the top surface of the circular seat 11. The top of the bracket is provided with a standard screw hole, which is adapted to the mounting interface of the prism, so that different types of prisms can be mounted on the top of the bracket.

[0025] A rotating disk 2 is fixedly installed at the bottom of a circular base 11. The diameter of the rotating disk 2 is the same as that of the circular base 11. Gear grooves 21 are evenly distributed along the circumference of the rotating disk 2. The rotating disk 2 is rotatably mounted on a mounting plate 3. A rotating shaft 22 is located at the center of the rotating disk 2. A center seat is located on the mounting plate 3, and the rotating shaft 22 is rotatably mounted on the center seat. An annular side plate 23 is also provided at the bottom of the rotating disk 2, and an annular groove is provided on the mounting plate 3. The annular side plate 23 is rotatably connected within the annular groove, allowing the rotating disk 2 to rotate smoothly on the mounting plate 3. A rotation drive unit 4 is fixed to one side of the mounting plate 3. The rotation drive unit 4 consists of a drive motor 41 and a set of reduction gear grooves 42. The reduction gear grooves 42 mesh with the gear grooves 21 of the rotating disk 2. When the motor operates, it drives the rotating disk 2 to rotate.

[0026] A control unit 13 is provided on the circular base 11. The control unit 13 is connected to the rotation drive unit 4. The control unit 13 includes a microprocessor, a wireless communication module, a power supply module, and a motor drive circuit. The power supply module supplies power to the microprocessor, the wireless communication module, and the motor drive circuit. The position feedback module provides real-time feedback of the rotation angle. The position feedback module, the microprocessor, and the wireless communication module can be directly selected from relevant structures in the prior art, which will not be described in detail.

[0027] In this embodiment, the operation steps are as follows:

[0028] Step 1, Installation and Debugging: Place base 5 at the observation point, adjust the bottom leveling screw, and observe the small bubble level to keep the rotating disk 2 level;

[0029] The second step is control signal reception: Control unit 13 receives remote commands via a wireless communication module. The wireless communication module can receive signals via Bluetooth, 5G network, or other methods. After receiving the commands, the microprocessor of control unit 13 controls the motor of rotary drive unit 4, causing the motor to operate and thus rotating the rotary disk 2 and circular base 11 to a suitable angle, thereby rotating the prism to the appropriate angle. It then works in conjunction with the total station to perform measurement operations.

[0030] The automatic rotating prism base provided by this utility model includes a base 5, a rotating seat 1, a rotation drive unit 4, and a lifting drive unit 6. The rotating seat 1 includes a circular base 11 and a prism mounting bracket 12 disposed on the circular base 11. A rotating disk 2 is fixedly installed at the bottom of the circular base 11. The rotating disk 2 is provided with a toothed groove 21 along its circumference. A mounting plate 3 is provided at the bottom of the rotating disk 2. The rotating disk 2 is rotatably mounted on the mounting plate 3. The rotation drive unit 4 is disposed on the mounting plate 3. The rotating disk 2 is connected to the rotation drive unit 4 through transmission. A control unit 13 is provided on the circular base 11. During use, the control unit 13 receives control signals and can drive the rotation drive unit 4, thereby causing the rotating disk 2 to rotate to a suitable angle. This realizes the remote automatic rotation adjustment of the prism, effectively solving the problems of low efficiency and poor accuracy of traditional manual operation. It is suitable for surveying scenarios such as full-circle observation and multi-point synchronous monitoring.

[0031] In this embodiment, the lifting drive unit 6 is mounted on the base 5, and the mounting plate 3 is mounted on the lifting drive unit 6. The mounting plate 3 is driven by the lifting drive unit 6 and can move up and down. The lifting drive unit 6 is connected to the control unit 13. There are two lifting drive units 6, and the two lifting drive units 6 are symmetrically mounted on the base 5.

[0032] The lifting drive unit 6 adopts a structure of cylinder and piston rod cooperation, and the two lifting drive units 6 are installed symmetrically inside the base 5. The cylinder of each lifting drive unit 6 is fixed on the base 5, and the top of the piston rod is connected to the bottom of the mounting plate 3. The two cylinders are connected to a solenoid valve through an air pipe. The solenoid valve is then connected to an external air source or an internal air pump. The solenoid valve is connected to the control unit 13. A sensor for detecting height is installed on the outside of the cylinder, and the sensor signal line is also connected to the control unit 13 to realize real-time feedback of height information.

[0033] Before use, a gas source must be prepared to ensure stable air pressure. During operation, after receiving a remote lifting command, the control unit 13 obtains the current height of the cylinders on both sides through sensors, and then controls the solenoid valve to operate: when lifting is required, the gas source supplies air into the cylinder, pushing the piston rod to extend and causing the mounting plate 3 to rise; when lowering is required, the cylinder exhausts air, the piston rod retracts, and the mounting plate 3 lowers accordingly. After reaching the target height, the solenoid valve closes, and the cylinder maintains pressure and locks in position; if adjustment is needed, the command can be sent again to complete the action.

[0034] In this embodiment, preferably, the base 5 has an installation chamber inside, which includes a circular cavity 51 and a rectangular cavity 52 that are connected to each other. The circular cavity 51 is located directly above the rectangular cavity 52. ​​An installation plate 53 is provided inside the rectangular cavity 52. ​​The lifting drive unit 6 is fixedly installed on the installation plate 53. The lifting drive unit 6 is vertically fixedly installed on the installation plate 53.

[0035] In this embodiment, preferably, the mounting plate 3 is movably connected to the circular cavity 51. The circular cavity 51 is provided with a clearance groove corresponding to the rotary drive unit 4. The size of the circular cavity 51 is larger than the size of the mounting plate 3, providing sufficient space for the lifting and lowering movement of the mounting plate 3. The clearance groove prevents the rotary drive unit 4 from colliding with the wall of the circular cavity 51 when the mounting plate 3 drives the rotary drive unit 4 to lift and lower. The interior of the cylindrical body 54 is provided with a guide channel, and the bottom of the mounting plate 3 is provided with a guide rod 31. The guide rod 31 is slidably connected in the guide channel. When the mounting plate 3 moves up and down, the guide rod 31 at the bottom of the mounting plate 3 always slides in the guide channel of the cylindrical body 54, limiting the horizontal offset of the mounting plate 3 and ensuring that the mounting plate 3 remains horizontal during the lifting and lowering process, thereby ensuring the stability of the upper rotating seat 1 and the prism.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
