[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] Embodiment 1, as Figure 1 and Figure 2As shown, a geotechnical engineering monitoring device that is easy to adjust includes four legs 4 distributed in a rectangular shape, a monitoring instrument storage structure 3 is commonly provided at the upper ends of the four legs 4, a lifting structure 6 is provided at the lower part of the inner cavity of the monitoring instrument storage structure 3, a geotechnical monitoring instrument 5 is fixedly installed at the upper end of the lifting structure 6, a supporting structure 2 is symmetrically provided at the upper end of the monitoring instrument storage structure 3, and a shoulder strap 1 is commonly fixedly connected at one end of the two supporting structures 2 that are far away from each other.

[0038] It should be noted that the above-mentioned support structure 2 is a conventional geotechnical detection equipment with a surveying and mapping probe in the prior art. It is an advanced geotechnical engineering detection equipment that integrates surveying and mapping technology. It can accurately spatially locate and map the rock and soil layers while detecting the physical properties of the rock and soil. This structure has been widely used in the prior art. In the present invention, it is only used to realize the function of geotechnical data monitoring, and its internal structure, operating principle, wiring, and control method will not be described in detail.

[0039] The four legs 4 are all rotatably connected to the lower part of the monitor storage structure 3, and can be folded and stored in the lower part of the monitor storage structure 3, which is convenient for carrying with the shoulder strap 1. At the same time, the monitor storage structure 3 can be auxiliary supported before unfolding. After unfolding, due to the action of the support structure 2, the legs 4 will leave the ground and be suspended in the air.

[0040] Specifically, in order to provide an installation place for the geotechnical monitoring instrument 5, the lifting structure 6, and the support structure 2 and to store the geotechnical monitoring instrument 5 and the lifting structure 6 during the carrying process to avoid collisions therewith, refer to Figure 3 and Figure 4 The monitoring device storage structure 3 includes a storage box 31 rotatably connected to the upper ends of the plurality of legs 4. The inner surface of the storage box 31 is provided with four groups of straight slide grooves 36 in a rectangular distribution. Two straight slide grooves 36 in the same group are vertically distributed. The inner surfaces of the four vertical straight slide grooves 36 are provided with J-shaped slide grooves 37. The inner surfaces of the J-shaped slide grooves 37 and the straight slide grooves 36 are slidably connected to the lifting structure 6.

[0041] The monitoring instrument storage structure 3 also includes two U-shaped slides 32 that are slidably connected to the support structure 2 and are jointly opened at the upper end and left and right ends of the storage box 31. The two U-shaped slides 32 are symmetrically distributed front to back. The left and right ends of the storage box 31 are symmetrically fixedly connected with racks 34 front to back. The left and right ends of the storage box 31 are symmetrically fixedly connected with limiting teeth 35 located on the lower side of the rack 34 front to back. The horizontal parts of the two U-shaped slides 32 are symmetrically opened with notches 38 on the left and right sides. Four notches 33 are opened in a rectangular distribution on the upper end of the storage box 31. A lock hole 39 connected to the right end is opened on the upper left end of the storage box 31. The inner surface of the storage box 31 is rotatably connected with a plurality of elastic connecting rods rotatably connected to the support structure 2 in a rectangular distribution.

[0042] The slot 33 is used to place the telescopic rod when unfolding to avoid it getting stuck. The rack 34 is used to work with the support structure 2 to drive it to unfold. The limit tooth 35 limits the support structure 2 after it is in place to avoid shaking. The U-shaped slide 32 is used to limit the running trajectory of the support structure 2. At the same time, the U-shaped slide 32 and the lock hole 39 are used to limit the support structure 2 after unfolding; the straight slide 36 cooperates with the J-shaped slide 37 to work with the lifting structure 6 to drive its operation.

[0043] The telescopic rod used to connect the storage box 31 and the cover plate 21 is a conventional technical means in the prior art. A spring and a sliding piston rod are arranged inside the telescopic rod, which can provide an inward pulling force while being telescopic. It is a mature technical means, and its internal structure and details will not be displayed and explained in the present invention.

[0044] Further, in order to provide protection for the geotechnical monitoring instrument 5 when carried and to provide support for the equipment when deployed, refer to Figure 2 and Figure 5 The support structure 2 includes a cover plate 21 located at the upper end of the storage box 31, a lifting assembly 22 is provided at the upper end of the cover plate 21, a storage box 23 is fixedly connected to the upper inner surface of the cover plate 21, and a support assembly 24 is fixedly connected to the lower inner surface of the cover plate 21.

[0045] The cover 21 is equivalent to a box cover, which is used to protect the geotechnical monitor 5 when carrying and storing to prevent damage to the equipment. The storage box 23 can store some regular documents, accessories, auxiliary equipment and other equipment required for monitoring. When unfolded, the lifting component 22 cooperates with the lock hole 39 to lock the position of the cover 21 to prevent the cover 21 from sliding.

[0046] Further, in order to guide the running track of the cover plate 21 and guide the support structure 2 to run along the L-shaped folding line track when unfolding, refer to Figure 6 and Figure 7 The end of the cover plate 21 close to the opposite cover plate 21 is symmetrically slidably connected with a connecting wheel 26, and the ends of the two connecting wheels 26 away from the opposite cover plate 21 are fixedly connected with a compression spring 261 fixedly connected to the cover plate 21. The connecting wheel 26 is adapted to the shape of the notch 38. The lower end of the cover plate 21 close to the opposite cover plate 21 is symmetrically rotatably connected to the limiting block 25. The connecting groove between the limiting block 25 and the cover plate 21 is symmetrically fixedly connected with rubber particles 251. The outer surface of the limiting block 25 is slidably connected to the inner surface of the U-shaped slide 32.

[0047] The lower limit block 25 can cooperate with the U-shaped slide 32 to guide the support structure 2 to slide along the L-shaped track on the upper end and the side of the monitor storage structure 3. During this process, the limit block 25 is first in a vertical state. At this time, it is located in the horizontal part of the U-shaped slide 32 and slides on the horizontal part of the U-shaped slide 32. When the limit block 25 passes the turning part, it will pass over the rubber particles 251 and rotate to a horizontal state. The rubber particles 251 are elastic particles that can block the rotation of the limit block 25 under a small force. However, when the force is greater than its bearing range, the limit block 25 can compress the rubber particles 251 to deform and rotate to a horizontal state. The vertical to horizontal state conversion is similar.

[0048] At this time, the limit block 25 is in the vertical part of the U-shaped slide 32 and continues to slide in the vertical part of the U-shaped slide 32, thereby driving the cover plate 21 to slide downward along the side of the storage box 31 until the lifting assembly 22 is engaged with the lock hole 39 to lock the cover plate 21;

[0049] Furthermore, in the initial state, the connecting wheel 26 will be pressed into the interior of the cover plate 21 due to the closure of the two side covers 21. At this time, the compression spring 261 is compressed. When the two side covers 21 are separated, the connecting wheel 26 slides out from the interior of the cover plate 21 under the action of the compression spring 261. When the cover plate 21 slides downward along the side of the storage box 31, the connecting wheel 26 is above the notch 38 and can enter the vertical part of the U-shaped slide 32 through the notch 38, thereby assisting the U-shaped slide 32 to position the cover plate 21.

[0050] During the operation of this embodiment, the lifting assembly 22 is first used to pull the cover plate 21 to slide along the track of the U-shaped slide 32 above the storage box 31, and at the same time, the travel path of the support structure 2 is limited by the cooperation of the limit block 25 and the U-shaped slide 32, thereby realizing the expansion of the cover plate 21 to both sides of the storage box 31, and the support structure 2 is driven to expand by the cooperation of the support assembly 24, the rack 34, and the limit tooth 35, thereby realizing the support of the storage box 31, and the cover plate 21 is locked by the cooperation of the lock hole 39 and the lifting assembly 22 to ensure the stability of the support, and the geotechnical monitor 5 is driven to rise to the predetermined height for detection by the cooperation of the lifting structure 6 and the monitor storage structure 3, and the support assembly 24 is synchronously driven to extend when the lifting structure 6 drives the geotechnical monitor 5 to rise, so as to adjust the height of the equipment.

[0051] Embodiment 2. Based on Embodiment 1, this embodiment drives the movement of the connecting rod 2 66 through the action of the threaded rod 2 63 and the slider 62, and pushes the lifting assembly 61 to move along the trajectory defined by the monitor storage structure 3 and the J-shaped slide groove 37 in the vertical direction through the connecting rod 2 66. Simultaneously, the cooperation of the lifting assembly 61 and the J-shaped slide groove 37 prompts the lifting assembly 61 to continue to push the geotechnical monitor 5 upward after the connecting rod 2 66 is at the maximum stroke, thereby realizing the pushing of the geotechnical monitor 5 out of the storage box 31 to facilitate the monitoring of the external geotechnical environment.

[0052] Specifically, in order to achieve the purpose of driving the rock and soil monitoring instrument 5 to rise to a predetermined height, refer to Figure 3 The lifting structure 6 includes a threaded rod 63 rotatably connected to the bottom wall of the inner cavity of the storage box 31 through a left-right symmetrical bearing bracket and a driving motor 64 installed on the bottom wall of the inner cavity of the storage box 31 through a motor bracket. The left and right ends of the threaded rod 63 are fixedly connected to a magnetic coupling 65 that is transmission-connected to the support structure 2. The outer surface of the threaded rod 63 is symmetrically threaded with a slider 62. The front and rear ends of the two sliders 62 are rotatably connected to a roller rod 67 that is slidably connected to the inner surface of the horizontal notch 38. The outer surfaces of several roller rods 67 are rotatably connected to connecting rods 66. The ends of several connecting rods 66 away from the roller rod 67 are commonly provided with a lifting component 61 that is slidably connected to the inner surface of the vertical notch 38. The upper end of the lifting component 61 is fixedly connected to the lower end of the geotechnical monitoring instrument 5, and the output end of the driving motor 64 is transmission-connected to the threaded rod 63 through a coupling.

[0053] The driving motor 64 drives the threaded rod 2 63 to rotate at the bottom of the inner cavity of the storage box 31 through the coupling. During the rotation of the threaded rod 2 63, due to the action of the thread and the limitation of the bottom wall of the storage box 31, the slider 62 will slide on the bottom wall of the inner cavity of the lifting assembly 61, and its movement trend is to approach or move away from each other. When the sliders 62 approach each other, they will push the connecting rod 2 66 to move along the internal path of the two notches 38 on the same side, that is, the connecting rod 2 66 is transformed from a nearly horizontal inclined state to a vertical state. At this time, one end of the connecting rod 2 66 in the vertical straight slide groove 36 will gradually move upward, thereby pushing the lifting assembly 61 to move upward along the path of the straight slide groove 36 and the J-shaped slide groove 37, thereby driving the lifting assembly 61 and the geotechnical monitoring instrument 5 to rise.

[0054] Further, in order to realize the continuous upward movement of the rock and soil monitoring instrument 5 during the operation of the driving motor 64, refer to Figure 8The lifting assembly 61 includes a plurality of linearly distributed rectangular frames 611, and the ends of the two rectangular frames 611 located at the upper and lower parts that are close to each other are symmetrically connected to short rods 612 for rotation. The inner surfaces of the plurality of rectangular frames 611 located in the middle part are rotatably connected to levers 613. The levers 613 on the two adjacent rectangular frames 611 are rotatably connected through limit bolts. The two levers 613 close to the short rods 612 are rotatably connected to the short rods 612 through limit bolts. The upper end of the short rod 612 located at the lower part is fixedly connected to a round rod 614 that is slidably connected to the inner surfaces of the two J-shaped slide grooves 37 on the same side. The front and rear ends of the rectangular frame 611 located at the lower part are symmetrically fixedly connected to roller rods 615 that are slidably connected to the inner surfaces of the adjacent vertical straight slide grooves 36.

[0055] First, when the angle of one side of the lever 613 between the rectangular frames 611 changes, the angle of the other side will change accordingly, and because their distribution is bilaterally symmetrical, the levers 613 on both sides will limit the movement direction of the rectangular frame 611, so that it can only move up and down;

[0056] Under this premise, when the connecting rod 2 66 pushes the rectangular frame 611 upward through the roller rod 1 615, the round rod 614 will first slide in the vertical part of the J-shaped slide 37. At this time, the distance between each rectangular frame 611 remains unchanged, and the geotechnical monitor 5 rises following the rising speed of the connecting rod 2 66 until the geotechnical monitor 5 begins to exceed the upper end of the storage box 31. At this time, the round rod 614 will enter the arc part of the J-shaped slide 37. At this time, the relative position of the round rod 614 changes, thereby driving the two short rods 612 at the bottom to be converted from the inclined state of being close to each other at the upper part to a vertical state. Due to the change in the angle of the short rod 612, the angle of the lever 613 connected thereto will also change relatively. At this time, since the lever 613 is of fixed length, the angle change will cause the distance between the rectangular frames 611 on both sides of the same lever 613 to change, until the lever 613 is completely vertical and the distance between the rectangular frames 611 is the largest. After the cooperation of multiple levers 613 and rectangular frames 611, the geotechnical monitor 5 is completely withdrawn from the storage box 31, and the external geotechnical environment can be monitored.

[0057] Embodiment 3: Based on Embodiment 2, this embodiment further locks the cover plate 21 after the cover plate 21 is unfolded to the side of the U-shaped slide 32 through the cooperation between the lock tongue 225 and the lock hole 39, so as to prevent the cover plate 21 from being offset due to gravity and thus affecting the stability of the device. In addition, the connection shaft 244 is driven to rotate through the cooperation between the spur gear 245 and the rack 34 in the support assembly 24, and the support assembly 24 is driven to convert from a horizontal state to a vertical state during the rotation of the connection shaft 244, thereby providing support to the device through the support component 243;

[0058] Synchronously, the transmission action of the magnetic coupling 1 65 and the magnetic coupling 2 242 is utilized to drive the magnetic coupling 2 242 to rotate, thereby driving the transmission rod 2431 to rotate, and the transmission action of the threaded ring 2433 on the transmission rod 2431 drives the threaded rod 1 2434 to rotate, and the action of the threaded rod 1 2434 and the threaded ring 2433 causes the support rod 2436 to extend from the connecting rod 1 2435, and the height of the geotechnical monitoring instrument 5 is adjusted by changing the overall length of the support component 243.

[0059] Specifically, in order to lock the position of the cover plate 21 to avoid shaking and ensure the stability of the support, refer to Figure 5 and Fig.10 The lifting assembly 22 includes a handle 221 fixedly connected to the upper end of the cover plate 21, a cable 223 fixedly connected to the lower end of the horizontal part of the handle 221, a movable block 222 located at the lower part of the horizontal part of the handle 221 fixedly connected to the outer surface of the cable 223, an end of the movable block 222 away from the handle 221 is fixedly connected to a locking tongue 225 slidably connected to the inner cavity of the cover plate 21, and an end of the locking tongue 225 close to the handle 221 is fixedly connected to a compression spring 224 fixedly connected to the inner cavity of the cover plate 21.

[0060] Similar to the connecting wheel 26, when the cover plates 21 on both sides are brought together, the cover plates 21 are tightly fitted together and locked due to the lock buckle on the upper side. At this time, the lock tongue 225 is inside the cover plate 21, and the compression spring 1 224 is compressed.

[0061] When the cover 21 is pulled to both sides by holding the handle 221 and the movable block 222, the locking tongue 225 will not pop out due to the traction of the handle 221 and the movable block 222. When the cover 21 reaches the side of the storage box 31, the movable block 222 is released and the locking tongue 225 enters the locking hole 39, thereby locking the position of the cover 21. When resetting, it is only necessary to hold the cable 223 and hook the movable block 222 upwards to detach it from the locking hole 39 by pulling the cable 223.

[0062] Further, in order to realize the coordination between the rack 34 and the limiting tooth 35, the support assembly 24 is unfolded to support the device, see Fig.10 and Fig.11The support assembly 24 includes a mounting box 241 fixedly connected to the inner cavity of the cover plate 21, and the inner surface of the mounting box 241 is symmetrically rotatably connected with a connecting shaft 244. The outer surfaces of the two connecting shafts 244 are linearly distributed and fixedly connected with a plurality of supporting components 243, and the plurality of supporting components 243 are staggered. One end of the two connecting shafts 244 close to the opposite side cover plate 21 penetrates the inner surface of the mounting box 241 and extends to the outer surface of the mounting box 241 and is fixedly connected with a spur gear 245. The spur gear 245 corresponds to the position of the rack 34. The front part of the inner cavity of the mounting box 241 corresponds to the position of the magnetic coupling 1 65 and is rotatably connected with a magnetic coupling 2 242 that is transmission-connected to the support component 243.

[0063] First of all, it should be specially explained that the connection between the connecting shaft 244 and the inner wall of the installation box 241 is connected through a damping ring. Without being subjected to a large external force, it will not produce autonomous rotation or offset rotation due to a slight touch.

[0064] Under this premise, when the spur gear 245 passes through the rack 34, the strong force of the meshing exceeds the resistance of the connecting shaft 244 and the mounting box 241, which can drive the connecting shaft 244 to rotate, and the transmission ratio of the spur gear 245 and the rack 34 can just drive the connecting shaft 244 to rotate 90 degrees, thereby driving the supporting component 243 to change from a horizontal state to a vertical state.

[0065] Further, in order to achieve the process of driving the lifting structure 6 to drive the geotechnical monitoring instrument 5 to rise and fall, the support assembly 24 is simultaneously driven to extend to adjust the height of the equipment, see Fig.11 The supporting component 243 includes a connecting rod 2435 fixedly connected to the outer surface of the connecting shaft 244, a supporting rod 2436 is slidably connected to the inner surface of the connecting rod 2435, a threaded ring 2433 is fixedly connected to the side of the inner surface of the support rod 2436 close to the connecting shaft 244, a threaded rod 2434 is threadedly connected to the inner surface of the threaded ring 2433, and an end of the threaded rod 2434 close to the connecting shaft 244 passes through the connecting rod 2435 and the connecting shaft 244, extends to the inner cavity of the connecting shaft 244 and is transmission-connected to a bevel gear set 2432 fixedly connected to the inner cavity of the connecting shaft 244, and a plurality of input gears of the bevel gear set 2432 are transmission-connected together to a transmission rod 2431 connected to the magnetic coupling 2 242 through a belt drive.

[0066] After the cover plate 21 is in place, the magnetic poles of the magnetic coupling 1 65 and the magnetic coupling 2 242 coincide with each other, and the magnetic coupling 2 242 can be driven to rotate by electromagnetic action, so that the transmission rod 2431 is driven to rotate by the belt, and the rotation of the transmission rod 2431 can be transmitted to the threaded rod 1 2434 through the bevel gear action in the bevel gear set 2432, and the support rod 2436 is driven to move downward through the threaded action of the threaded rod 1 2434 and the threaded ring 2433. At this time, the support rod 2436 extends from the connecting rod 1 2435 to lift the equipment and adjust the monitoring height of the equipment;

[0067] It should be specially noted that the above-mentioned drive motor 64 and magnetic coupling 242 are electromagnetic couplers in the prior art, which are conventional couplers that utilize strong magnetic interaction to transmit rotational power. They can utilize magnetism to transmit power across the air at a small distance, which is a conventional technical means in the prior art. They are often used in stirring equipment that requires strict sealing, and have been widely used in the field of modern technology. In the present invention, only the functions of transmission across the air and free separation are utilized, and their internal structure and specific operating principle are no longer displayed or elaborated.

[0068] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
