At the same time, the foldable legs are a retractable structure, and are in a stowed state under normal conditions. The upper ends of the support legs 5 are circumferentially evenly distributed on the lower end of the turntable 4. The lower end of the turntable 4 is fixedly connected with a driving column 6 extending downward and coaxially arranged. A liftable driving sheet 7 is arranged in the driving column 6. A vertically arranged sliding groove 9 is provided on the inner side of the upper end of the support leg 5. An adjusting sheet 11 is vertically slidably connected in the sliding groove 9. The adjusting sheet 11 is connected to the corresponding position of the driving sheet 7 through an intermediate rod 12, so that each support leg 5 can be controlled to be unfolded when the driving sheet 7 is lifted or lowered. The turntable 4 is rotatably connected to the lower end of the support plate 2, and a worm 21 for driving is rotatably connected inside the turntable 4, and a rotating seat 3 is provided at the lower end of the support plate 2 inside the turntable 4. The worm 20 on the outer edge of the rotating seat 3 is connected to the worm shaft to control the stable rotation of the turntable 4. The upper end of the support plate 2 is connected to the support platform 1 through an inclination adjustment mechanism. The inclination adjustment mechanism is used to fine-tune the angle between the support platform 1 and the support plate 2, so that the upper end surface of the support platform 1 is always at the angle required for the working state. A fastening structure for connecting the detection equipment is provided on the support platform 1, and the detection equipment is fixed and replaced through the fastening structure.

[0032] The utility model comprises a support platform 1 for fixing the detection instrument, and the detection instrument is positioned by the fastening structure on the support platform 1, and it is convenient to replace after the positioning is completed; the upper end surface of the support platform 1 is fixedly connected with an upward positioning column 13, and a plurality of buckles 14 are evenly distributed on the outer circumference of the positioning column 13; the upper end of each buckle 14 extends with a guide bayonet toward the center of the positioning column 13, and the guide bayonet extends obliquely downward toward the inside, so that during installation, the detection instrument is pressed downward through the guide of the guide buckle 14, and the upper end of the buckle 14 is squeezed outward and buckled on the positioning column 13; and a reset spring 15 is provided between the outer side of each buckle 14 and the support platform 1, and the reset card of the reset spring 15 is connected to the detection instrument, so as to position the detection instrument and prevent the detection instrument from falling off; when the detection instrument needs to be replaced, the upper end of the buckle 14 is opened outward, and then the detection instrument that has lost its positioning is taken out and replaced.

[0033] An inclination adjustment mechanism is provided between the lower end of the support platform 1 and the support plate 2. When in use, the posture of the support plate 2 only needs to be positioned in a rough orientation, and then the upper end surface of the support platform 1 is finely adjusted through the inclination adjustment mechanism. The inclination adjustment mechanism includes a hinge ball 16 located in the middle of the lower end surface of the support platform 1 and the middle of the upper end surface of the support plate 2, and a plurality of symmetrically arranged adjustment springs 17 are provided on the outer side of the hinge ball 16.

The adjusting rope 18 is wound by the rope winder 19. Since the adjusting rope 18 is symmetrically arranged on the outside of the articulated ball 16, two symmetrically arranged rope winders 19 form a group. When one of the rope winders 19 is winding, the other rope winder 19 rotates in the opposite direction and releases the line, so that the support platform 1 rotates along the articulated ball 16. The rotation amplitude corresponds to the adjusting rope 18 wound by the winder. Furthermore, a spirit level is fixed on the support platform 1, and the data of the spirit level is corresponded to the winding length of each rope winder 19, so that the rope winder 19 is electrically controlled to automatically and accurately wind, so that the upper end surface of the support platform 1 can be more accurately rotated to the corresponding angle during operation.

[0034] A rotating seat 3 extending downward is fixedly connected to the lower end surface of the support plate 2, and an annularly arranged turbine 20 teeth are provided on the outer circumference of the rotating seat 3. A turntable 4 rotatably connected to the rotating seat 3 is sleeved on the rotating seat 3. A worm 21 arranged perpendicular to the axis of the turntable 4 is rotatably connected inside the turntable 4. The worm 21 cooperates with the turbine 20 teeth. A driving motor for driving the worm 21 to rotate is fixedly connected to the turntable 4. During the rotation of the driving motor, the rotating seat 3 and the turntable 4 are driven to rotate, thereby adjusting the orientation of the support plate 2.

[0035] A driving column 6 extending downward and coaxially arranged with the turntable 4 is fixedly connected to the lower end of the turntable 4. The driving column 6 is a hollow structure. A driving motor is fixedly connected to the lower end of the driving column 6. The driving motor shaft is coaxially arranged with the driving column 6 and extends upward. A driving piece 7 is vertically slidably connected in the driving column 6. The driving motor shaft passes through the driving piece 7 and is threadedly matched with the driving piece 7. The driving piece 7 is controlled to move up and down by rotating the driving motor shaft. A plurality of supporting legs 5 are rotatably connected to the lower end surface of the turntable 4 outside the driving column 6. The circumference of each supporting leg 5 is uniformly distributed on the outside of the driving column 6. Vertically arranged openings are respectively opened on the side surfaces of the outer side of the driving column 6 and corresponding to each supporting leg 5. Each supporting leg 5 The upper end is rotatably connected to the lower end surface of the turntable 4, the lower end of each supporting leg 5 is a telescopic rod, and the lower end of each supporting leg 5 is fixedly connected with a ground plug 23, and a vertically arranged sliding groove 9 is opened at the upper end of the supporting leg 5, and each sliding groove 9 has an opening facing the side of the driving column 6, and an adjusting threaded rod 10 is rotatably connected in each sliding groove 9, and an adjusting plate 11 is vertically slidably connected in each sliding groove 9, and the adjusting threaded rod 10 passes through the adjusting plate 11 and is threadedly connected with the adjusting plate 11, and an intermediate rod 12 is respectively provided between the driving plate 7 and each adjusting plate 11, and one end of each intermediate rod 12 is rotatably connected to the driving plate 7, and the other end is rotatably connected between the corresponding adjusting plates 11.

[0036] During the initial adjustment, the position of the adjustment piece 11 in the sliding groove 9 remains unchanged, and the deployment action of each support leg 5 is adjusted by lifting and lowering the drive piece 7 located in the drive column 6. When the drive piece 7 is lifted and lowered by the rotation of the drive rod 8, the corresponding support legs 5 are synchronously deployed through the connection of the intermediate rods 12, and then the deployment amplitude is adjusted according to the terrain. When the deployment angle of a specific support leg 5 needs to be changed due to different terrains, it is driven by the adjustment threaded rod 10 on the corresponding support leg 5. When the adjustment threaded rod 10 rotates, the position of the adjustment piece 11 in the sliding groove 9 is driven to change. When the position of the adjustment piece 11 moves along the sliding groove 9, the deployment angle of the support leg 5 is changed, thereby completing the adjustment of the deployment angle of the specific support leg 5 after each support leg 5 is synchronously deployed.

[0037] At the lower end of each supporting leg 5 is a telescopic leg, which includes a plurality of telescopic rods. The outer side of the lower end of the supporting leg 5 and the outer side of the lower end of the telescopic rod are respectively provided with a tension knob 22 for positioning the telescopic rod after it is extended. The telescopic rod is positioned after it is extended by rotating the tension knob 22.

[0038] A ground plug 23 is provided at the lower end of the telescopic rod at the lowest end. The ground plug 23 is a columnar structure with a sharp lower end for easy insertion into the ground. A limit plate 24 is provided at the upper end of the ground plug 23 and is arranged perpendicular to the ground plug 23. The limit plate 24 is used to prevent the ground plug 23 from being inserted too deeply into the ground. At the same time, the insertion depth into the ground is unified according to the position of the limit plate 24. A columnar auxiliary fixing piece is provided between the upper end of the limit plate 24 and the lower end of the telescopic rod. The upper end of the auxiliary fixing piece and the lower end of the telescopic rod can be fixedly connected or rotatably connected. The auxiliary fixing piece is used to assist the ground plug 23 in being inserted into the ground and to assist in positioning the lower end of the support rod. A longitudinal through groove 26 is longitudinally penetrated on the auxiliary fixing piece, and a pressing auxiliary piece 27 and an arc-shaped support piece 28 are rotatably connected at both ends of the longitudinal through groove 26.

[0039] The pressing auxiliary piece 27 is used to assist in pressing when the ground plug 23 is inserted into the ground. The lower end of the pressing auxiliary piece 27 is rotatably connected to the lower end of the longitudinal through groove 26. The upper end of the pressing auxiliary piece 27 is hidden in the longitudinal through groove 26 when not in use. When in use, the upper end of the pressing auxiliary piece 27 is unfolded outward and is limited by the lower end surface of the longitudinal through groove 26 when it is perpendicular to the outer side surface of the auxiliary fixing part. At this time, when the ground plug 23 is inserted downward into the ground, the ground plug 23 is inserted into the ground by stepping on it or hammering it with a heavy object to provide stable support.

[0040] The arc-shaped support piece 28 is used in complex environments where support cannot be provided in woodlands or on the ground. The upper end of the arc-shaped support piece 28 is rotatably connected in the longitudinal through groove 26. The arc-shaped support piece 28 is an arc-shaped structure, and the concave side surface of the arc-shaped support surface extends inward. When it is impossible to find a suitable fulcrum on the ground in woodlands and other places and a stable measurement environment is required, unfold each support leg 5, unfold the upper end of the arc-shaped support piece 28 along the rotating connection part, and then support the arc-shaped support piece 28 on a tree trunk or rock in the forest as a fulcrum. Since the contact surface between the arc-shaped support piece 28 and the fulcrum is a concave arc, it can reduce slip resistance and avoid unstable support problems. The arc-shaped support piece 28 is also hidden in the longitudinal through groove 26 when not in use, avoiding the inconvenience of transportation caused by unfolding when not in use.

[0041] An adjusting threaded rod 10 is rotatably connected in the sliding groove 9 at the upper end of the supporting leg 5, and the lower end of the adjusting threaded rod 10 extends downwardly out of the sliding groove 9. A pinion 29 is fixedly connected to the part where the lower end of the adjusting threaded rod 10 extends out of the sliding groove 9, and an adjusting member 30 arranged parallel to the axis of the pinion 29 is rotatably connected at the corresponding position of the pinion 29 on the supporting leg 5. The adjusting member 30 includes a mating gear that cooperates with the pinion 29, and a toggle disk is provided on the side of the mating gear. The outer circumference of the toggle disk is evenly distributed with anti-slip grooves, and the outer side of the toggle disk extends to the side of the supporting leg 5, so that the toggle disk can be manually driven during use, thereby manually adjusting the position of the adjusting plate 11 in the sliding groove 9, and the adjusting plate 11 is connected to the driving plate 7 by an intermediate rod 12. The deployment angle of a single supporting leg 5 can be changed by changing the position of the adjusting plate 11, thereby adapting to different environments.

[0042] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
