[0040] The end of the locking sleeve 206 close to the passive ring 208 is slidably provided with a plurality of locking blocks 207, the inside of the passive ring 208 is fixedly provided with a plurality of top blocks 209, and the top block 209 is arc-shaped and in contact with the outer surface of the locking block 207;

[0041] Specifically, when the rubber anti-skid sleeve of the locking block 207 is pressed tightly, the contact pressure is converted into a large friction force, so as to realize reliable locking. Therefore, the three inner protective shells 201 can realize height locking on a flat foundation and also realize height locking on an inclined foundation.

[0042] Example 2: please refer to Figure 4 、 Figure 5 、 Figure 8The application discloses a pile foundation pre-embedded part positioning device for mountain photovoltaic engineering, which is based on the foundation of the embodiment 1 and comprises a response sleeve 401, a connecting arm 102 is rotationally connected with the response sleeve 401 on the side away from the matching sleeve 101, so that the matching sleeve 101 moves upwards and drives the response sleeve 401 to move upwards through the connecting arm 102 during the upward movement of the matching sleeve 101, a buffer cylinder 402 is fixedly installed at the upper end of the response sleeve 401, a supporting frame 403 is detachably installed on the outer surface of the buffer cylinder 402, and a driven gear 404 is rotationally installed at the inner end of the supporting frame 403.

[0043] The driven gears 404 are divided into two groups, a plurality of water drop blocks 406 are rotationally installed at the ends close to each other of the two groups of driven gears 404, the water drop blocks 406 are arranged in a ring shape, a plurality of limiting blocks are arranged between the two groups of driven gears 404, the limiting blocks limit the rotation of the water drop blocks 406 within a limited angle range, a rack 204 is fixedly installed on the outer surface of the central pipe 202, the rack 204 is engaged with the water drop blocks 406 arranged in a ring shape, specifically, the rotation of the central pipe 202 can drive the rack 204 to rotate and disengage from the water drop blocks 406, to avoid interference, the rack 204 is designed not to be engaged with the driven gears 404, and the width of the rack 204 is smaller than that of the water drop blocks 406, so that the rotation is smooth.

[0044] The driven gears 404 and the supporting frame 403 are clamped through a reset torsion spring 405, when the buffer cylinder 402 moves upwards, the water drop blocks 406 are limited by the limiting blocks and cannot rotate, after being in contact with the rack 204, the linear motion is transmitted to the driven gears 404, so that the driven gears 404 are forced to rotate, the reset torsion spring 405 is charged when the driven gears 404 rotate, and the water drop blocks 406 move reversely in the release stage of the reset torsion spring 405, at this time, the swinging direction of the water drop blocks 406 is out of the action range of the limiting blocks, so the water drop blocks 406 are not limited by the limiting blocks, so that the driven gears 404 can be normally reset and rotated;

[0045] A transmission gear 407 is rotationally installed at the inner end of the supporting frame 403, the transmission gear 407 is engaged with the driven gears 404, an auxiliary wheel 409 is rotationally installed at the inner portion of the supporting frame 403, a driving wheel is fixedly installed on the surface of the transmission gear 407, and the driving wheel and the auxiliary wheel 409 are tightly sleeved through a transmission belt 408, specifically, a tensioner is arranged in the supporting frame 403, the tension of the transmission belt 408 can be automatically maintained, and the driving force of the driving wheel can be efficiently transmitted to the auxiliary wheel 409;

[0046] The outer surface of the auxiliary wheel 409 is fixedly installed with a power hammer 410, which uses rotational inertia to accumulate and provide the required potential energy. The buffer cylinder 402 falls with the rotation of the power hammer 410, and the self-locking of the clamping plate 103 on the positioning sign 2 directly converts this downward potential energy into driving force on the positioning sign 2. The downward pressure of the worker on the positioning sign 2 is combined with the auxiliary power of the power hammer 410 to make the positioning sign 2 penetrate deeper into the foundation, and the support frame 403 can be flexibly detached from the buffer cylinder 402, so that different weights of power hammers 410 can be replaced according to different terrains.

[0047] Please refer to Figure 5 、 Figures 9-12 The horizontal auxiliary device includes a connecting block 301 fixedly installed at the upper end of the outer shell 3, a pull ring 302 rotatably installed at the upper end of the connecting block 301 and fixedly connected with the central pipe 202, a rotating frame 306 rotatably installed at the inner end of the outer shell 3 and rotatably connected with the balance sleeve 4 at the free end of the rotating frame 306. Specifically, the rotating frame 306 is angularly self-locked through the built-in damping shaft, and the balance sleeve 4 connected therewith is freely rotatable.

[0048] The connecting block 301 is internally provided with a passive frame 304, the upper end of the passive frame 304 is slidably installed with an active column 303, and the active column 303 is connected with the connecting block 301 through a return spring 307. The outer surface of the pull ring 302 is provided with a notch, and when the notch on the surface of the pull ring 302 rotates to the position of the active column 303 during rotation, the active column 303 is embedded therein to realize positioning. The outer surface of the passive frame 304 is fixedly connected with a synchronous pipe 305, and the synchronous pipe 305 is internally provided in the active column 303.

[0049] The balance sleeve 4 is internally fixedly installed with a float 310, the float 310 is internally filled with a liquid, the upper end of the float 310 is detachably installed with a sealing cover 308, the sealing cover 308 is fixedly connected with the synchronous pipe 305, the sealing cover 308 is internally provided with a passive plug 311, the bottom end of the passive plug 311 is fixedly installed with a protrusion, the inner end of the float 310 is fixedly installed with a stabilizing ring 309, the inner end of the stabilizing ring 309 is provided with a top rod 312, the stabilizing ring 309 only limits the active area of the top rod 312, the top rod 312 can be deflected at any angle, the upper end of the top rod 312 is in contact with the protrusion at the bottom end of the passive plug 311, and the end of the top rod 312 away from the stabilizing ring 309 is fixedly connected with a floating ring 313.

[0050] Specifically, the density of the floating ring 313 is smaller than the liquid in the buoy 310, and the liquid in the buoy 310 only submerges half of the height of the floating ring 313, the bottom end of the sealing cover 308 is bowl-shaped, and therefore the top rod 312 always maintains the upward moving force under the action of the buoyancy of the floating ring 313, and only when the buoy 310 is in the vertical state, the top rod 312 pushes the passive plug 311 upward;

[0051] It is worth noting that the sealing cover 308 is provided with a limiting block, which can prevent the protrusion at the bottom end of the passive plug 311 from being completely retracted into the sealing cover 308, and the diameter of the top rod 312 is greater than the protrusion at the bottom end of the passive plug 311;

[0052] The buoyancy of the liquid in the buoy 310 on the floating ring 313 is greater than the total mass of the movable column 303 and the passive frame 304.

[0053] The working principle of the application is as follows:

[0054] When in use, the outer shell 3 is unfolded, and the unfolding angle of the outer shell 3 is limited to ensure that the response sleeve 401 can smoothly descend, guarantee its function is not affected, and pull out the inner shell 201 from it, if the ground is flat, after the inner shell 201 is pulled out, the driving ring 302 is directly rotated, the driving ring 302 drives the adapter rod 203 to rotate through the central pipe 202, then the adapter rod 203 drives the passive ring 208 to rotate through the central rod 205, when the passive ring 208 rotates, the outer surface of the top block 209 will extrude and push the locking block 207, so that the locking block 207 moves towards the direction of the central rod 205, and finally contacts with the outer surface of the central rod 205, and realizes the locking of the central rod 205, so that the inner shell 201 no longer continues to move;

[0055] If the ground is inclined, after fixing the positions of two inner shells 201, the balance sleeve 4 on the side without the fixed inner shell 201 is pulled out, at this time, the passive frame 304 moves downward under the action of gravity, then, the outer shell 3 on the locking side of the inner shell 201 can be slowly rotated, when the outer shell 3 is tentatively rotated, the floating ring 313 in the buoy 310 always remains horizontal, the top end of the top rod 312 is gradually pushed to the protrusion at the bottom end of the passive plug 311, until the protrusion is contacted and pushed upward, then the passive plug 311 moves upward and is transmitted to the inside of the movable column 303 through the synchronous pipe 305, so that the movable column 303 moves upward, at this time, the worker observes that the movable column 303 moves, and starts to rotate the last driving ring 302 to lock the height of the last inner shell 201, in the process of rotating the central pipe 202, the rack 204 is engaged with the water drop block 406;

[0056] At this time, the device has completed automatic leveling on the inclined foundation and stabilized in a horizontal state. Then the positioning pin 2 is inserted from the positioning cylinder 1 and through the inside of the matching sleeve 101. As the positioning pin 2 penetrates into the foundation, if it continues to penetrate, the matching sleeve 101 moves under the action of the clamping plate 103 as the positioning pin 2 is pulled out. As the matching sleeve 101 moves upward, the response sleeve 401 is driven to move by the connecting arm 102. At this time, the water droplet block 406 drives the passive gear 404 to rotate under the meshing action of the rack 204. When the passive gear 404 rotates, the reset torsional spring 405 is energized;

[0057] Then the positioning pin 2 is pressed again. At this time, the reset torsional spring 405 is no longer stressed, and it begins to release the elastic force, which drives the passive gear 404 to rotate. At this time, the transmission gear 407 rotates under the meshing action of the passive gear 404, and drives the auxiliary wheel 409 to rotate through the transmission belt 408. The buffer cylinder 402 falls as the power hammer 410 rotates. The self-locking of the clamping plate 103 on the positioning pin 2 directly converts this downstroke potential energy into driving force on the positioning pin 2. The worker's pressing force on the positioning pin 2 and the auxiliary power of the power hammer 410 work together to make the positioning pin 2 penetrate deeper into the foundation. This reciprocation continues until the positioning pin 2 penetrates to a satisfactory depth.

[0058] When the work is completed, the knob 302 is rotated to end the height locking of the inner shell 201, and the balance sleeve 4 is retracted into the outer shell 3. The inner shell 201 is pushed back into the outer shell 3 to complete the storage.

[0059] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent substitutions or changes within the scope of the disclosed technology and according to the technical solution and inventive concept of the present application, which should be covered within the protection scope of the present application.
