[0002] In architectural design and geological survey, surveying equipment is a key equipment to ensure project quality and design accuracy. In actual operation, especially in complex and changeable construction sites, the installation and leveling process of surveying equipment is particularly cumbersome, time-consuming, and difficult to ensure the accuracy of surveying results. When setting up traditional surveying equipment, it is usually necessary to manually adjust screws and other methods to ensure that the horizontal bubble of the surveying equipment is in the center. This process requires not only precise operating skills, but also repeated observation and adjustment until the ideal horizontal state is achieved. However, on uneven and irregular ground, due to the ups and downs and irregular shapes of the ground, traditional leveling methods often fail to achieve the desired effect, and may even lead to inaccurate surveying data.

[0003] Therefore, there is an urgent need for a special-shaped ground frame for surveying and mapping, which can quickly provide a horizontal base for the surveying and mapping device. Summary of the invention

[0033] A solar photovoltaic panel 6 is installed at the edge of the upper surface of the platform 1 , and the solar photovoltaic panel 6 is electrically connected to the battery 16 through an inverter.

[0034] The hydraulic cylinder 4 is hinged on the lower surface of the platform 1, and the hydraulic cylinder 4 can be rotated to achieve unfolding or folding.

[0035] An upper articulated seat 8 is fixedly mounted on the lower surface of the platform 1 , an upper articulated head 20 is provided at the end of the hydraulic cylinder 4 , the upper articulated head 20 is hinged on the upper articulated seat 8 , and an unfolding limiting seat 19 and a folding limiting seat 18 are provided on the upper articulated seat 8 .

[0036] The folding limiting seat 18 and the unfolding limiting seat 19 are made of permanent magnets, and the upper hinged head 20 is made of magnetic attraction material.

[0037] A lower hinged joint 21 is provided at the end of the telescopic rod 5 , and the lower hinged joint 21 is hinged to the ground contact seat 7 .

[0038] Anti-slip teeth 22 are provided on the contact surface between the ground contact seat 7 and the ground.

[0039] Working principle of this embodiment:

[0040] When this embodiment is working, first place the platform on the ground, then press the switch button 3 for automatic leveling, and place the surveying device on the platform 1 after the leveling is completed. After starting, the horizontal sensor 15 immediately starts working to detect the current tilt state of the platform 1. The sensor can accurately measure the tilt angle of the platform in all directions and transmit these data to the control mainboard 17. After receiving the data from the horizontal sensor 15, the control mainboard 17 performs a quick analysis and calculates the length that each hydraulic cylinder 4 needs to be extended or shortened to achieve the ideal horizontal state. Subsequently, the control mainboard 17 sends an opening or closing signal to the corresponding solenoid valve 11. According to the instructions of the control mainboard 17, the solenoid valve 11 controls the flow direction of the hydraulic oil in the oil distribution pipe 10, thereby driving the telescopic rod 5 in the hydraulic cylinder 4 to extend or shorten. This process is dynamically adjusted, that is, as the platform 1 gradually tends to be horizontal, the horizontal sensor 15 continues to feedback data, and the control mainboard 17 continuously corrects the instructions until the platform reaches a completely horizontal state. Once the platform 1 reaches a horizontal state, the control main board 17 will maintain the current state of the solenoid valve 11 to ensure that the hydraulic cylinder 4 is locked in the correct position, thereby maintaining the stability of the platform.

[0041] This embodiment realizes the rapid automatic leveling of the surveying and mapping device by combining the electronic control system with the hydraulic system, greatly shortens the time for erection and leveling, and improves work efficiency. The precise coordination between the level sensor 15 and the control main board 17 ensures that the platform 1 can achieve very high horizontal accuracy, and can ensure the accuracy of the surveying and mapping data even on uneven and irregular ground. Due to the use of multiple hydraulic cylinders 4 for independent adjustment, the device can adapt well to various complex terrains, and can achieve effective leveling regardless of whether it is undulating or irregularly shaped ground. The user only needs to operate the switch to start the entire leveling process, without the need for professional operating skills, which reduces the difficulty of operation and improves the convenience of use. The locking function of the hydraulic cylinder 4 ensures that the platform 1 can remain stable after leveling, and will not easily change the horizontal state due to external factors such as wind, vibration, etc., further ensuring the reliability of the surveying and mapping data.

[0042] Level 2 is a bubble level that uses the principle of gravity. When platform 1 is in a horizontal state, the bubble will be located within the central scale line of the level. If the platform tilts, the bubble will move accordingly, indicating the direction and degree of the tilt. This provides the user with an intuitive visual feedback to help determine whether the platform has reached a horizontal state.

[0043] The solar photovoltaic panel 6 captures sunlight and converts it into electrical energy. This electrical energy is converted into direct current suitable for charging the battery 16 through an inverter. The inverter ensures that the unstable alternating current output from the photovoltaic panel is converted into stable direct current, which is then stored in the battery 16 for use by the surveying and mapping special-shaped ground frame when needed. This method reduces dependence on traditional power sources and improves the self-sufficiency of the equipment.

[0044] The hydraulic cylinder 4 is hinged to the upper hinge seat 8 on the lower surface of the platform 1 through the upper hinge head 20 at its upper end, so as to realize the function of unfolding or folding. When it is needed, the hydraulic cylinder is unfolded to support the platform 1 through the telescopic rod 5 and the ground contact seat 7; when it is not needed, the hydraulic cylinder can be folded and folded to reduce the size of the equipment and facilitate carrying and storage.

[0045] The expansion limiting seat 19 and the stowage limiting seat 18 are used to provide positioning when the hydraulic cylinder is expanded and stowed, respectively. They are made of permanent magnets, and the upper hinge head 20 is made of magnetic material. When the hydraulic cylinder rotates to a predetermined expansion position or stowage position, the upper hinge head 20 will be attracted and fixed by the corresponding limiting seat 19 or 18, thereby ensuring the stability and accuracy of the hydraulic cylinder, simplifying the positioning process of the hydraulic cylinder, and improving the reliability and ease of use of the equipment.

[0046] The end of the telescopic rod 5 is provided with a lower hinge joint 21, which is hinged to the ground contact seat 7, allowing the ground contact seat to rotate relative to the telescopic rod within a certain range to adapt to different ground inclination angles and shapes. The contact surface between the ground contact seat 7 and the ground is provided with anti-skid teeth 22, which can increase the friction with the ground, prevent the equipment from sliding or shifting during use, and ensure the accuracy and safety of surveying and mapping.
