DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0029] As shown in the accompanying drawings Figure 1 - the accompanying drawings Figure 8 The multi-terrain tripod for geological exploration shown in the accompanying drawings is provided with a support assembly on the support seat 1. Air is filled into the air bag 25 through the conduit 13, the top plate 24 is pushed to move upward along the guide frame 23 until the height of the support point is balanced with other points, the air pressure is stabilized at a certain pressure, the pressure relief valve 9 is opened to release air if the air pressure of a certain air bag 25 is too high, the air pressure of the air bag 25 of each support assembly is consistent, the horizontal calibration of the tripod is realized, and the specific structural arrangement of the assembly is as follows.

[0030] The support assembly includes a hinge seat 2 mounted on a support base 1. A hinge frame 3 is hinged to one side of the hinge seat 2. A first hinge rod 4 is hinged to the hinge frame 3. A second hinge rod 5 is hinged to one end of the first hinge rod 4. A connecting block is hinged to one end of the second hinge rod 5. An adjusting block 6 is provided on one side of the connecting block. The end of the connecting block extends to one end of the hinge frame 3 and is hinged to the hinge frame 3. An elastic band 7 is provided at the bottom of the adjusting block 6, and the elastic band 7 is filled with a non-Newtonian fluid.

[0031] As attached Figure 3 , 5 As shown in Figures 6 and 7, the first hinge rod 4 deflects along the axis point where the first hinge rod 4 connects to the hinge frame 3, thereby changing the angle of the second hinge rod 5 on the hinge frame 3. When the second hinge rod 5 deflects, it drives the adjusting block 6 to rotate along the axis point where the connecting block connects to the hinge frame 3 through the connecting block, thereby realizing the function of adjusting the level of the adjusting block 6 so that the elastic band 7 can contact the ground. When the elastic band 7 is subjected to force, it will squeeze the non-Newtonian fluid inside. Under the static gravity of the non-Newtonian fluid, the shear rate of the fluid is extremely low, and its behavior is closer to that of ordinary liquid. It will flow downward naturally due to gravity, so that the bottom of the airbag contacts the ground and is deformed by pressure, thereby allowing the airbag to adapt to the shape of the ground and ensure the stability of the support.

[0032] The adjusting block 6 includes a guide frame 23 and a top plate 24. The connecting block is fixed on the top plate 24, and an airbag 25 is provided between the top plate 24 and the guide frame 23. A pressure sensor 8 is provided on the top plate 24, and a pressure relief valve 9 is provided on one side of the pressure sensor 8. Both the pressure sensor 8 and the pressure relief valve 9 pass through the top plate 24 and extend into the airbag 25.

[0033] As attached Figure 5 , 6 As shown in Figure 8, the pressure sensor 8 is used to detect the air pressure inside the airbag 25 so as to inject airflow into the airbag 25. At the same time, the pressure relief valve 9 is set to discharge excess air pressure inside the airbag 25, so as to ensure that the pressure inside the airbag 25 of each support component is the same and to ensure the stability of the horizontal support.

[0034] An air guide ring 10 is provided at the top of the inner cavity of the support base 1, and a conduit 13 is provided at the bottom of the air guide ring 10. One end of the conduit 13 passes through the top plate 24 and extends to the airbag 25. A solenoid valve is provided at the connection between the air guide ring 10 and the conduit 13.

[0035] As attached Figure 4 , 5As shown in Figures 6 and 8, after the airflow is gathered by the air guide ring 10, it is diverted through the duct 13. The duct 13 injects high-pressure airflow into the airbag 25, causing the airbag 25 to inflate. When the airbag 25 inflates, the top plate 24 extends out from the guide frame 23 along the guide frame 23. At the same time, by adjusting the pressure in each airbag 25, the height of each top plate 24 can be adjusted. When the top plate 24 is displaced, it drives the connecting block to move, making it easy to adjust horizontally. Furthermore, the guide frame 23 guides the top plate 24, which can effectively ensure the stability of the top plate 24 when it is displaced, and also ensure the stability of the subsequent support of the tripod.

[0036] A micro air pump 11 for guiding airflow is provided on the outer side of the air guide ring 10, and a processor 12 is provided on the top of the air guide ring 10. Both the processor 12 and the micro air pump 11 are embedded in the top of the inner cavity of the support base 1.

[0037] As attached Figure 4 As shown, the pressure sensor 8 detects the air pressure inside the airbag 25 and analyzes it through the processor 12 so that the processor 12 can control the operation of the micro air pump 11 to draw the airflow into the air guide ring 10, and inject it into the airbag 25 after being diverted by the solenoid valve and the conduit 13, so as to facilitate the adjustment of the air pressure inside each airbag 25.

[0038] A worm gear 14 is rotatably connected to the middle of the support base 1, and a first worm wheel 15 is rotatably connected to the hinge base 2. The first worm wheel 15 meshes with the worm gear 14, and a second motor 19 for driving the worm gear 14 to rotate is provided at the bottom of the processor 12.

[0039] As attached Figure 3 As shown, the worm gear 14 is driven to rotate by the second motor 19 so that the first worm wheel 15 can rotate when the worm gear 14 rotates.

[0040] A second worm gear 16 is fixedly provided at one end of the first hinge rod 4 facing the first worm gear 15. The second worm gear 16 meshes with the first worm gear 15. A crossbar 17 is rotatably connected to the middle of the second worm gear 16. The crossbar 17 is fixed at one end of the hinge frame 3, and a first motor 18 for driving the crossbar 17 to rotate is provided on the outside of the hinge seat 2.

[0041] As attached Figure 5 and 6 As shown, the first worm gear 15 and the second worm gear 16 mesh with each other so that when the first worm gear 15 rotates, it drives the second worm gear 16 to rotate, thereby allowing the first hinge rod 4 to deflect for angle adjustment. The crossbar 17 is fixed to the end of the hinge frame 3, so that the second motor 19 can drive the crossbar 17 to rotate the hinge frame 3, thereby changing the angle of the hinge frame 3. By changing the angle of the hinge frame 3, the deflection of the first hinge rod 4 can drive the second hinge rod 5 and the adjusting block 6 to deflect, so that the hinge frame 3 and the adjusting block 6 can be horizontal, ensuring support performance.

[0042] The top of the support base 1 is provided with a silk cylinder 20, a screw rod 21 is threadedly connected in the silk cylinder 20, and a supporting plate 22 is arranged at the top of the screw rod 21;

[0043] As shown in the accompanying drawings Figure 1 and 2 The surveying equipment can be placed on the supporting plate 22, the screw rod 21 is extended out of the silk cylinder 20 by rotating the screw rod 21 and the supporting plate 22, and the height of the supporting plate 22 is adjusted.

[0044] The top plate 24 is embedded in the guide frame 23 and is in sliding connection with the guide frame 23, and the vertical sectional shape of the adjusting block 6 is triangular.

[0045] As shown in the accompanying drawings Figure 8 The sliding connection between the top plate 24 and the guide frame 23 facilitates the upward displacement of the top plate 24 when the air bag 25 is inflated, and facilitates the upward displacement of the connecting block, the hinge frame 3, the first hinge rod 4, the second hinge rod 5 and the hinge base 2 when the top plate 24 is displaced upward, thereby adjusting the level of the support base 1.

[0046] The second worm gear 16 is embedded in the end of the first hinge rod 4, and the second worm gear 16, the cross rod 17 and the connection between the first hinge rod 4, the hinge frame 3 and the hinge base 2 are all in the same axial direction.

[0047] As shown in the accompanying drawings Figure 3 , 5 and 6, the first hinge rod 4 is rotated along the axial direction of the cross rod 17 through the second worm gear 16, and the hinge frame 3 is rotated along the axial direction of the connection between the cross rod 17 and the hinge base 2 through the cross rod 17, so as to adjust the angle between the hinge frame 3 and the first hinge rod 4.

[0048] The electromagnetic valve, the pressure sensor 8, the pressure relief valve 9 and the micro air pump 11 are all connected with the processor 12 through wires, and the output end of the micro air pump 11 is in communication with the air guide ring 10.

[0049] As shown in the accompanying drawings Figure 4 The output end of the micro air pump 11 is in communication with the air guide ring 10, which facilitates the air flow to be delivered into the air guide ring 10 by the micro air pump 11, and the electromagnetic valve is opened after the processor 12 adjusts the electromagnetic valve on each conduit 13, so that the air flow in the air guide ring 10 is delivered into the air bag 25 through the conduit 13.

[0050] Specific working principle as follows, when the tripod is placed on the ground, the first motor 18 drives the crossbar 17 to rotate, drive the hinge frame 3 around the hinge seat 2 rotation, so that the support assembly is radial expansion. At this time, the second motor 19 starts to drive the worm 14 rotation, through the meshing of the first worm gear 15 and the second worm gear 16 drive the first hinge rod 4 deflection, in turn push the second hinge rod 5 drive the adjusting block 6 to extend downward. The elastic belt 7 of the adjusting block 6 contacts the ground, the internal non-newtonian fluid fills the ground gap due to gravity, forming a flexible support surface.

[0051] The pressure sensor 8 real-time monitoring of the air pressure in the air bag 25, when a support point ground height is lower, the air bag 25 is pressed to reduce, the air pressure value is lower than the processor 12 preset threshold, the processor 12 trigger micro air pump 11 to inject gas flow to the guide air ring 10, the electromagnetic valve of the corresponding conduit 13 is opened, the gas flow is filled into the air bag 25 through the conduit 13, the top plate 24 is pushed along the guide frame 23 to move up, until the height of the support point is balanced with other points, so that the air pressure is stable at a certain pressure, if the air pressure of the air bag 25 is too high, the pressure relief valve 9 is opened to exhaust, to ensure that the air pressure of each support assembly is consistent, to realize the horizontal calibration of the tripod.

[0052] When it is necessary to adapt to the slope terrain, the processor 12 controls the second motor 19 to adjust the rotation of the worm 14, so that the first worm gear 15 drives the second worm gear 16 to rotate, and the angle between the first hinge rod 4 and the hinge frame 3 is changed. For example, on a 15° slope, the first hinge rod 4 of the left support assembly can be deflected by 20°, and the right side can be deflected by 10°, and the angle difference is used to compensate for the terrain inclination. At this time, the self-locking characteristics of each worm gear and the worm 14 can prevent the support assembly from retracting due to external force, and ensure the stability of the support;

[0053] And the surveying instrument is placed on the supporting plate 22, and the height can be adjusted by rotating the screw rod 21 in the rotating wire barrel 20. When fine adjustment of the instrument direction is needed, the processor controls the air pressure difference of the air bag of each support assembly, for example, the air inflation of the left air bag 25 is increased by 10kPa, and the right side is reduced by 10kPa, so that the support seat 1 produces a small inclination, and the mechanical angle adjustment is used to realize the attitude adjustment of the instrument in the horizontal direction ± 15°, without the need to move the tripod position, improving the convenience of installation and regulation.

[0054] The above is only the preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
