[0029] like Figure 4 and Figure 5 As shown, a spirit level 10 for assisting leveling is provided on the adjustment seat 2 .

[0030] like Figure 4 and Figure 5As shown, the power device is a motor 3 , and the motor 3 is electrically connected to the battery 12 .

[0031] like Figure 1 、 Figure 4 and Figure 6 As shown, the tripod 1 is a retractable tripod 1 .

[0032] Principle and operation process

[0033] After the instrument is set up, the controller 11 first operates the array of motors 3, lowering the adjustment base 2 to a position close to the battery 12 for subsequent lifting and leveling operations. If the adjustment base 2 is not level, the controller 11 selects one set of motors 3 and places them in standby mode, while the remaining motors 3 remain deactivated. At this point, the metal ball 6 within the movable slot 5 begins rolling under the influence of gravity, with its rolling position information transmitted via the contacts it contacts. When the metal ball 6 rolls to either side of the movable slot 5's length and contacts the slider 72 and second contact 8, two scenarios exist: First, the adjustment base 2 is tilted. Contact with the slider 72 exerts pressure, forcing it to slide within the contact slot 71, thereby bringing it into contact with the first contact 7. Because the distance from the second contact 8 to the side of the first contact 7 is equal to the radius of the metal ball 6, the metal ball 6 also contacts the second contact 8. In this way, the first contact 7 and the second contact 8 will receive signals simultaneously, indicating that the adjustment base 2 is not horizontal. At this time, the motor 3 on the side where the metal ball 6 is located will start, driving that side upward; secondly, the adjustment base 2 is in a horizontal state. Although the metal ball 6 contacts the second contact 8, it does not push the slider 72 to contact the first contact 7. In this case, the metal ball 6 may have moved toward this side due to inertia during the lifting process of the other side. This means that the automatic adjustment of that position has been completed. When the automatic adjustment of one position is completed, the controller 11 controls the other adjacent group of motors 3 to enter the standby state and repeat the above steps until the metal balls 6 in all movable slots 5 in the array no longer trigger the first contact 7. This indicates that the adjustment base 2 has reached a horizontal state. If neither the first contact 7 nor the second contact 8 triggers, it also indicates that leveling is complete. At this point, the spirit level 10 installed on the adjustment base 2 can be used for auxiliary verification. In addition, a limit ring is provided at the bottom end of the adjustment nut to effectively prevent the adjustment bolt 4 from falling off during the adjustment process. The contact slot 71, spring 73, and slider 72 at first contact point 7 ensure that when metal ball 6 strikes first contact point 7, slider 72 slides within contact slot 71. Spring 73 acts as a buffer, mitigating potential errors in information transmission caused by continued forward movement of metal ball 6 due to inertia, thereby ensuring leveling accuracy. The rotating disk 21 on adjustment base 2 is connected to compass 9, allowing for easy rotation of compass 9 during forestry surveys, enabling convenient measurement of different directions.

[0034] Specific operation method: Open the retractable tripod 1. Adjust the tripod 1 to the appropriate height based on the actual measurement environment and needs, and ensure it is firmly placed on the ground. The base 101 on the tripod 1 supports the entire automatic leveling mechanism and compass 9. After confirming that the battery 12 is properly connected to the motor 3 and other equipment, turn on the power switch. The controller 11, contacts, motor 3, and other components will enter a ready state. After the power is turned on, the automatic leveling mechanism automatically begins to operate. The metal ball 6 begins to roll within the movable groove 5 according to the tilt of the adjustment base 2. When the metal ball 6 contacts the first contact 7 or the second contact 8, the contacts transmit a signal to the controller 11. After receiving the signal from the contacts, the controller 11 activates the motor 3 according to a preset program. The motor 3 drives the adjustment bolt 4 to thread into the threaded hole of the base 101, thereby adjusting the horizontal angle of the adjustment base 2. During this process, the metal ball 6 continuously changes position as the adjustment base 2 is adjusted until the first contact 7 is no longer triggered. After automatic leveling is complete, observe the spirit level 10 on the adjustment base 2. If it indicates that the adjustment base 2 is completely level, proceed to the next step. If it still isn't completely level, check the stability of the tripod 1 or manually operate the controller 11 to control one of the motors 3 to bring the adjustment base 2 to a completely level state. After the adjustment base 2 is leveled, rotate the compass 9 using the rotary dial 21 to adjust it to the desired orientation. Then, read the data from the compass 9 and record and analyze it according to the specific needs of the forestry survey.

[0035] Although the above describes the specific implementation methods of the present invention in conjunction with the accompanying drawings, it does not limit the scope of protection of the present invention. On the basis of the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
