[0003] Before conducting surveying work, the support of the surveying instrument will be unfolded to first construct a relatively flat horizontal support platform. In a special complex terrain environment, in the traditional technology, it is not easy to quickly construct a relatively flat horizontal support surface using the leg structure, and the operator needs to make multiple selections and adjustments. Although the total station itself has the ability to adjust horizontally, the adjustment range is limited. It is necessary to first adjust the legs to a relatively flat support surface and then make adjustments, which is not conducive to the rapid deployment of the equipment. Content of the Utility Model

It is necessary to first adjust the legs to a relatively flat support surface and then make adjustments. In complex terrains, the legs cannot quickly construct a relatively flat support surface, which is not conducive to the rapid deployment of the equipment.
[0005] The utility model is realized as follows. An adjustable surveying instrument for complex terrains includes:
[0006] A bearing platform, where the bearing platform includes a fixed plate and an adjustment plate. A total station for testing is arranged on the fixed plate; a deflection rod is arranged on the end face of the adjustment plate away from the fixed plate.

[0008] A bottom bracket, where the bottom bracket includes an outer support ring and a bearing. An embedding ring is arranged at the bottom of the support platform, and the embedding ring is connected to the outer support ring through the bearing.
[0009] The bearing platform can obtain a 360° rotation ability through the cooperation of the adjustment platform and the bottom bracket, and the deflection rod deflects through the action of the deflection assembly, thereby driving the bearing platform to tilt relative to the ground.

The rotating shaft is located in the rotating groove, and the deflection rod is fixed to the rotating shaft. One end of the rotating shaft is connected to the worm gear, and the worm and the worm gear are meshed; the worm and the worm gear adopt the transmission principle of a worm and worm gear, so that the rotating shaft will drive the deflection rod to deflect, achieving the purpose of deflection adjustment. The worm and worm gear structure has a self-locking function, reducing the design of the locking device.
[0011] Preferably, the support platform and the embedding ring are in a stepped structure, and the embedding ring is integrally inserted into the outer support ring.
[0012] Preferably, an equipment chamber is provided inside the support platform. The worm extends from the side of the support platform ring to the equipment chamber.

[0031] An embodiment of the present utility model provides an adjustable surveying instrument for complex terrains, such as Figures 1-6 shown. The adjustable surveying instrument for complex terrains includes:
[0032] A carrier platform 100, which includes a fixed plate 110 and an adjustment plate 130. A total station for testing is provided on the fixed plate 110; the fixed plate 110 and the adjustment plate 130 are connected by a connecting column 120; a deflection rod 140 is provided on the end face of the adjustment plate 130 away from the fixed plate 110;
[0033] An adjustment platform 300 and a bottom bracket 200. The adjustment platform 300 includes a support platform. A rotation groove 310 is provided at the center of the support platform. The deflection rod 140 extends into the rotation groove 310; a deflection assembly is provided on the support platform. The deflection assembly includes a rotating shaft 410, a worm 420, and a worm gear 430. The rotating shaft 410 is located in the rotation groove 310, and the deflection rod 140 is fixed on the rotating shaft 410. One end of the rotating shaft 410 extends into the interior of the support platform and is connected to the worm gear 430, and the worm 420 and the worm gear 430 are meshed and connected;
[0034] The bottom bracket 200 includes an outer support ring 210 and a bearing 220. An embedding ring 330 is provided at the bottom of the support platform. The embedding ring 330 is connected to the outer support ring 210 through the bearing 220; and a hinge seat 230 is provided on the outer ring side of the outer support ring 210. The hinge seat 230 is hinged to an adjustable leg (not shown in this application) in the prior art. Here, both the hinge seat 230 and the adjustable leg adopt the prior art and will not be elaborated in detail;
[0035] In this application, the carrier platform 100 is supported by the adjustment platform 300, and the carrier platform 100 is rotationally connected to the adjustment platform 300 to obtain the function of pitch adjustment. The rotational connection between the adjustment platform 300 and the bottom bracket 200 helps the carrier platform 100 obtain the orientation adjustment ability. In this way, the carrier platform 100 can obtain a 360° rotation ability, and the deflection rod 140 deflects through the action of the deflection assembly to drive the carrier platform 100 to tilt relative to the ground;
[0036] When the adjustable legs are initially fixed and there is still a large inclination between the carrier platform 100 and the ground, with the help of the deflection function of the deflection assembly and the horizontal adjustment function between the adjustment platform 300 and the bottom bracket 200, the carrier platform 100 can be kept in a horizontal state with the horizontal plane to the greatest extent by rotation and pitch deflection, thereby reducing the need for horizontal adjustment of the total station; the adjustable surveying instrument for complex terrains can achieve horizontal adjustment through multiple means, improve the operation approach of the equipment, and speed up the efficiency of horizontal calibration;
[0037] As a preferred implementation manner in this embodiment, the support platform and the embedding ring 330 are in a stepped structure, and the embedding ring 330 is integrally inserted into the inner part of the outer support ring 210; the outer support ring 210 holds up the support platform;
[0038] A magnetic ring 320 is further provided on the support platform. The magnetic ring 320 is located on the circumferential side of the embedding ring 330, and the magnetic ring 320 is in contact connection with the outer support ring 210; here, the outer support ring 210 is made of a steel material that can be magnetically adsorbed. After the adjustment is completed, the magnetic ring 320 is magnetically connected to the outer support ring 210 through magnetic attraction, increasing the resistance to relative rotation between the support platform and the outer support ring 210; generally speaking, the torque during the rotation of the total station equipment is small, and the magnetic attraction effect generated by the magnetic ring 320 can prevent the support platform and the outer support ring 210 from rotating;
[0039] As a preferred implementation manner in this embodiment, an equipment bin is provided inside the support platform. The worm 420 extends from the side of the support platform ring into the equipment bin. One end of the rotating shaft 410 extends from the rotating slot 310 into the equipment bin. The worm gear 430 is arranged on the part of the rotating shaft 410 extending into the equipment bin, and the worm 420 is meshed with the worm gear 430;
[0040] In this embodiment, the worm 420 and the worm gear 430 adopt the transmission principle of a worm and worm gear. Here, the rotation of the worm 420 drives the rotation of the worm gear 430, and the rotating shaft 410 will drive the deflection rod to deflect accordingly; to achieve the purpose of deflection adjustment. Here, the worm 420 and the worm gear 430 do not need to be precisely adjusted horizontally, but only through rotational cooperation, the bearing platform 100 can reach the best position to reduce the adjustment amount of the total station;
