[0026] (1) Through the shock absorption mechanism in the shock absorption chamber, the present invention can perform shock absorption work. When moving, the mobile base may shake.

After connecting to the fixed teeth, drive the driving gear to rotate again. When rotating, it will drive the fixed column to descend through the fixed teeth, so that the limiting feet at the bottom of the fixed column extend out of the fixed feet, achieving the limiting effect.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0042] Please refer to Figures 1 - 10 As shown, the present application provides a geophysical exploration device for groundwater pollution investigation, including a mobile base 1, and further including:

[0043] A shock absorption mechanism 2, arranged on the mobile base 1, for placing the detector and realizing shock absorption of the detector;

[0045] A driving mechanism 4, connected to the fixing mechanism 3, for driving the fixing mechanism 3 to work;

[0046] Moving wheels 5, arranged at the bottom of the mobile base 1, for driving the mobile base 1 to move;

[0047] The shock absorption mechanism 2 includes a shock absorption chamber 21; the shock absorption chamber 21 is fixedly connected to the moving base 1; a telescopic groove 11 is formed in the middle of the moving base 1; a sliding column 12 is fixedly connected in the telescopic groove 11; a sliding block 14 is slidably connected to the sliding column 12; a side wall of the sliding block 14 is fixedly connected with a telescopic spring 13; one end of the telescopic spring 13 away from the sliding block 14 is fixedly connected to a side wall of the telescopic groove 11; there are two groups of the telescopic grooves 11; a hinge rod 15 is hinged to the sliding block 14; one end of the hinge rod 15 away from the sliding block 14 is hinged to a shock absorption plate 22; a shock absorption column 23 and a shock absorption spring 24 are fixedly connected to the bottom of the shock absorption plate 22; one ends of the shock absorption column 23 and the shock absorption spring 24 away from the shock absorption plate 22 are fixedly connected to the moving base 1; there are multiple groups of the shock absorption column 23 and the shock absorption spring 24;

[0048] During operation, in the prior art, when using a detection device, generally, the device is first moved to the place to be detected. When detecting outdoors, the detection device needs to be fixed before detection to avoid the device shifting or tipping during the detection process, which affects the final measurement. At the same time, according to the detection requirements, the device may detect while moving, but the movement will cause the device to shake. When shaking, the transmitting and receiving parts will vibrate. The greater the vibration, the lower the accuracy of the collected data. First, place the detector on the shock absorption plate 22 in the shock absorption chamber 21, then move the moving base 1 to the place where detection is required, and then use the fixing mechanism 3 to fix the moving base 1, and then start the detection work. At the same time, according to the detection requirements, when the moving base 1 needs to be moved, the shock absorption work can be carried out through the shock absorption mechanism 2 in the shock absorption chamber 21. When moving, the moving base 1 may shake. When shaking, the detector on the shock absorption plate 22 will shake. When shaking, the bottom telescopic spring 13 will be squeezed through the hinge rod 15, and at the same time, it will also be buffered by the shock absorption spring 24 and the shock absorption column 23. Through the settings of the telescopic spring 13 and the shock absorption spring 24, the shaking generated during movement can be greatly reduced, thereby protecting the detector from vibration and improving the detection accuracy.

[0049] Such as Figures 5 - 10As shown, the fixing mechanism 3 includes fixing feet 31; the fixing feet 31 are cylindrical; the inner wall of the fixing feet 31 is fixedly connected with a limiting bin 313; a limiting block 314 is slidably connected in the limiting bin 313; a fixing column 34 is slidably arranged inside the fixing feet 31; the side wall of the fixing column 34 is fixedly connected with the limiting block 314; the bottom of the fixing feet 31 is fixedly connected with a triangular block 32; one-way doors 33 are hinged to the side walls of the fixing feet 31 on both sides of the triangular block 32; the bottom of the fixing column 34 is hinged with limiting feet 35; there are two groups of limiting feet 35; a connecting groove 351 is formed in the side wall of the limiting feet 35; a connecting spring 352 is fixedly connected in the connecting groove 351; the limiting feet 35 are connected by the connecting spring 352;

[0050] During operation, when the moving base 1 moves to the target location, it is necessary to fix the moving base 1 to prevent the detector from moving during detection. When fixing, first drive the fixing feet 31 downward and insert the fixing feet 31 into the ground. Since it is for detecting groundwater, most of the detection sites are soil. After inserting the fixing feet 31 into the ground, then drive the fixing column 34 inside the fixing feet 31 to descend. When the fixing column 34 descends, it will drive the two groups of limiting feet 35 at the bottom to descend. When the limiting feet 35 descend, they will separate from the triangular block 32 inside the fixing feet 31, so that the limiting feet 35 move towards the one-way doors 33 on both sides and reach the outside of the fixing feet 31 as the fixing column 34 descends. The one-way doors 33 can only be opened from the inside of the fixing feet 31, and cannot be pushed from the outside, preventing soil from entering the fixing feet 31 through the one-way doors 33. When the limiting feet 35 extend out from the one-way doors 33, the limiting feet 35 will be inserted into the soil again, thereby limiting both sides of the fixing feet 31, thus strengthening the fixation of the fixing feet 31. When the limiting feet 35 are not needed for limiting, drive the fixing column 34 to rise. When rising, the limiting feet 35 retract into the fixing feet 31. During the retraction process, the connecting spring 352 rebounds to combine the two groups of limiting feet 35 for convenient storage.

[0051] As Figures 5 - 10As shown, the driving mechanism 4 includes a hexagonal column 41; a notch 17 is formed on the moving base 1; the hexagonal column 41 is rotatably connected in the notch 17; a driving gear 43 is sleeved on the hexagonal column 41; a lifting tooth 311 is fixedly connected to the side wall of the fixed foot 31; the driving gear 43 is meshed with the lifting tooth 311; a connecting disk 42 is also sleeved on the hexagonal column 41; a compression spring 421 is fixedly connected to the side wall of the connecting disk 42; one end of the compression spring 421 away from the connecting disk 42 is fixedly connected to the side wall of the notch 17; the connecting disk 42 is arranged on one side of the driving gear 43 and is slidably connected to the driving gear 43; a fixed tooth 341 is fixedly connected to the side wall of the fixed column 34; the fixed tooth 341 penetrates through the fixed foot 31 and is arranged parallel to the lifting tooth 311; a hand rocker 44 is rotatably connected to the side wall of the moving base 1; the output end of the hand rocker 44 is fixedly connected to the input end of the hexagonal column 41; a dial 441 is sleeved on the hand rocker 44; a pressing column 442 is fixedly connected to the side wall of the dial 441; the pressing column 442 penetrates through the notch 17; a ball 443 is rotatably arranged at one end of the pressing column 442 away from the dial 441; the ball 443 abuts against the driving gear 43; a pressing block 312 is fixedly connected to the top of the fixed foot 31;

[0052] When it is necessary to drive the fixed foot 31 to descend during operation, the operator can drive the hand crank to rotate. The hand crank drives the drive gear 43 on the hexagonal column 41 to rotate. When the drive gear 43 rotates, it drives the fixed foot 31 to descend through the lifting teeth 311. When fixing, first use the drive gear 43 to drive the fixed foot 31 to descend. When the fixed foot 31 descends to the maximum range of descent, the extrusion block 312 at the top of the fixed foot 31 will contact the drive gear 43 and extrude the drive gear 43, so that the drive gear 43 is extruded to be parallel to the fixed teeth 341, disconnecting the drive gear 43 from the lifting teeth 311 and connecting it to the fixed teeth 341. After connecting to the fixed teeth 341, drive the drive gear 43 to rotate again. When rotating, it will drive the fixed column 34 to descend through the fixed teeth 341, so that the limit feet 35 at the bottom of the fixed column 34 extend out of the fixed foot 31 to achieve the limiting effect. When canceling the fixation, reverse the drive gear 43, and then separate the extrusion block 312 from the drive gear 43. The extrusion spring 421 rebounds and springs the drive gear 43 back to a position parallel to the lifting teeth 311, and then the fixed foot 31 can be retracted. Moreover, the cooperation between the fixed foot 31 and the limit feet 35 can be adjusted according to the terrain. When the soil is shallow, the fixed foot 31 cannot reach the maximum range of descent. At this time, first lower the fixed foot 31 by a certain distance, and then press the paddle 441 on the hand rocker 44, so that the extrusion column 442 on the paddle 441 extrudes the drive gear 43 and extrudes it to be parallel to the fixed teeth 341, and then drive the fixed column 34 and the limit feet 35 to descend. At the same time, the end of the extrusion column 442 is provided with a ball 443, and the ball 443 also rotates when the drive gear 43 rotates.

[0053] As Figure 7 shown, a card slot 342 is formed on the side wall of the fixed column 34; a fixed bin 211 is fixedly connected to the side wall of the shock absorption bin 21; a fixed spring 212 is fixedly connected in the fixed bin 211; one end of the fixed spring 212 away from the fixed bin 211 is fixedly connected to a clamping block 213; the clamping block 213 is clamped in the card slot 342;

[0054] During operation, when the fixed foot 31 descends, the fixed column 34 will be clamped by the clamping block 213 in the fixed bin 211 to prevent the fixed column 34 from descending together with the fixed foot 31 when the fixed foot 31 descends. Moreover, the clamping block 213 is triangular. When the fixed foot 31 moves up and down, the clamping block 213 will be extruded into the fixed bin 211 and will be ejected by the fixed spring 212 to fix the fixed column 34 when it is parallel to the card slot 342.

[0055] As Figure 2 shown, two sets of universal wheels are provided and are respectively arranged on both sides of the moving base 1;

[0056] During operation, the moving base 1 and the detector can be moved through the universal wheels.

[0057] As Figure 2 shown, there are two sets of the telescopic grooves 11; sliding columns 12 are arranged in both of the two sets of telescopic grooves 11;

[0058] During operation, the telescopic springs 13 in the two sets of telescopic grooves 11 can greatly reduce the shaking caused during movement.

[0059] As Figure 1 shown, a handle 16 is fixedly connected to the side wall of the moving base 1;

[0060] During operation, the moving base 1 can be pushed through the handle 16.

[0061] Please refer to Figures 1 - 10 shown, the present application provides a geophysical detection method for groundwater pollution investigation, including the following steps:

[0062] S1. First, place the physical detector on the moving base 1, then move the moving base 1 and the detector to the point to be detected, and then adjust the parameters of the detector according to the detection requirements. After the adjustment is completed, fix the detector;

[0063] S2. When fixing, first insert the fixing feet 31 on the moving base 1 into the ground, and then use the limiting feet 35 inside the fixing feet 31 to fix the fixing feet 31 to prevent the fixing feet 31 from moving and affecting the detection;

[0064] S3. When mobile detection is required, retract the fixing feet 31, then move the moving base 1. During the movement, shock absorption work on the detector is performed through the shock absorption plate 22 inside to avoid large vibrations;

[0065] During operation, first place the physical detector on the moving base 1, then move the moving base 1 and the detector to the point to be detected, and then adjust the parameters of the detector according to the detection requirements. After the adjustment is completed, fix the detector. When fixing, first insert the fixing feet 31 on the moving base 1 into the ground, and then use the limiting feet 35 inside the fixing feet 31 to fix the fixing feet 31 to prevent the fixing feet 31 from moving and affecting the detection. When mobile detection is required, retract the fixing feet 31, then move the moving base 1. During the movement, shock absorption work on the detector is performed through the shock absorption plate 22 inside to avoid large vibrations.

[0066] Working principle of the present invention: In the prior art, when using a detection device, generally, the device is first moved to the place to be detected. When detecting outdoors, the detection device needs to be fixed before detection to avoid the device shifting or toppling during the detection process, which affects the final measurement. At the same time, according to the detection requirements, the device may detect while moving, but the movement will cause the device to shake. When shaking, the transmitting and receiving parts will vibrate. The greater the vibration, the lower the accuracy of the collected data. First, place the detector on the shock-absorbing plate 22 in the shock-absorbing chamber 21. Then, move the mobile base 1 to the place where detection is required, and then use the fixing mechanism 3 to fix the mobile base 1. Immediately start the detection work. At the same time, when it is necessary to move the mobile base 1 according to the detection requirements, the shock-absorbing mechanism 2 in the shock-absorbing chamber 21 can perform shock-absorbing work. When moving, the mobile base 1 may shake. When shaking, the detector on the shock-absorbing plate 22 will shake. When shaking, it will squeeze the telescopic spring 13 at the bottom through the hinge rod 15, and at the same time, it will also be buffered by the shock-absorbing spring 24 and the shock-absorbing column 23. Through the setting of the telescopic spring 13 and the shock-absorbing spring 24, the shaking generated during movement can be greatly reduced, thereby protecting the detector from vibrating and improving the detection accuracy.

[0067] When it is necessary to drive the fixed foot 31 to descend, the staff can drive the hand crank to rotate, and use the hand crank to drive the driving gear 43 on the hexagonal column 41 to rotate. When the driving gear 43 rotates, it drives the fixed foot 31 to descend through the lifting teeth 311. When fixing, first use the driving gear 43 to drive the fixed foot 31 to descend. When the fixed foot 31 descends to the maximum of the descendable range, the extrusion block 312 at the top of the fixed foot 31 will contact the driving gear 43 and extrude the driving gear 43, so that the driving gear 43 is extruded to be parallel to the fixed teeth 341, disconnecting the driving gear 43 from the lifting teeth 311 and connecting it to the fixed teeth 341. After connecting to the fixed teeth 341, drive the driving gear 43 to rotate again. When rotating, it will drive the fixed column 34 to descend through the fixed teeth 341, so that the limiting foot 35 at the bottom of the fixed column 34 extends out of the fixed foot 31 to achieve the limiting effect. When canceling the fixation, reverse the driving gear 43, and then disconnect the extrusion block 312 from the driving gear 43. The extrusion spring 421 rebounds to spring the driving gear 43 back to the position parallel to the lifting teeth 311, and then the fixed foot 31 can be retracted. Moreover, the cooperation between the fixed foot 31 and the limiting foot 35 can be adjusted according to the terrain. When the soil is shallow, the fixed foot 31 cannot reach the maximum of the descendable range. At this time, first lower the fixed foot 31 by a certain distance, and then press the paddle 441 on the hand rocker 44, so that the extrusion column 442 on the paddle 441 extrudes the driving gear 43 to make it parallel to the fixed teeth 341, and then drive the fixed column 34 and the limiting foot 35 to descend. At the same time, the end of the extrusion column 442 is provided with a ball 443, and the ball 443 also rotates when the driving gear 43 rotates.

[0068] The above has described an embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
