DETAILED DESCRIPTION

[0032] See also Figure 1 In an embodiment of the present invention, a survey vehicle for assisting geological radar detection includes a frame 1, wheels are connected to the frame around the frame, symmetrical frames 2 are fixedly connected to both sides of the upper end of the frame 1, handles are fixedly connected to the upper ends of the symmetrical frames 2, and a placement plate 4 is fixedly connected to the middle of the handle. The placement plate 4 is used to place a radar display screen, which is convenient for users to view the detection data of the radar in real time. A substrate 6 is clamped in the inner cavity of the frame 1, and a positioning mechanism for clamping and fixing the radar is provided in the middle of the upper end of the substrate 6. The positioning mechanism includes a turntable 10, a symmetrical slide groove 9 is slidably connected to the middle of the upper end of the substrate 6, and a clamping plate 8 is slidably connected to the inner cavity of the slide groove 9. The lower part of the clamping plate 8 is elastically connected to the inner cavity side wall of the slide groove 9 by a spring. When the turntable 10 rotates clockwise, the symmetrical clamping plates 8 are away from the center position of the turntable 10, and when the turntable 10 moves vertically downward, the symmetrical clamping plates 8 are close to the center position of the turntable 10.

[0033] See also Figure 2 , Figure 4and Figure 5 A mounting groove 11 is provided in the middle of the upper end of the base plate 6, and a rotating rod 12 is rotatably connected to the inner cavity of the mounting groove 11. A driven rod 101 is vertically slidably connected to the middle of the upper end of the rotating rod 12. The driven rod 101 is elastically connected to the bottom of the inner cavity of the rotating rod 12 through a spring. The upper end of the driven rod 101 is fixedly connected to the turntable 10, and a gear 13 is fixedly connected to the outer wall of the rotating rod 12. When the turntable 10 rotates, the rotating rod 12 will be driven to rotate through the driven rod 101, and then the gear 13 will be driven to rotate synchronously. The outer wall of the gear 13 is provided with two groups of racks 18 that are centrally symmetrical about the center position of the rotating rod 12. A push rod 19 is fixedly connected to the side of the rack 18 close to the splint 8. The rack 18 and the push rod 19 are both slidably connected to the inner cavity of the base plate 6, and the rack 18 and the gear 13 are meshed with each other. The two groups The rack 18 is only different in its position. The plane where the top of the rack 18 located at the top coincides with the upper end face of the gear 13, and the plane where the lower end of the rack 18 located at the bottom coincides with the lower end face of the gear 13. When the gear 13 rotates clockwise, it will drive the rack 18 to continuously move away from the position where the center of the circle of the rotating rod 12 is located. When the gear 13 has not yet rotated, the side of the push rod 19 away from the rotating rod 12 is in contact with the side wall of the splint 8, that is, the push rod 19 will only push the splint 8 away from the rotating rod 12, and will not drive the splint 8 close to the rotating rod 12. As the gear 13 rotates clockwise, the splint 8 will be pushed by the push rod 19 to continuously move away from the position of the rotating rod 12 in the inner cavity of the slide groove 9. By changing the spacing between the symmetrical splints 8, geological detection radars of different sizes can be adapted.

[0034] See also Figure 6, because a spring is arranged between the splint 8 and the inner cavity side wall of the slide groove 9, when the splint 8 moves away from the rotating rod 12, the spring is compressed, thereby applying an elastic force to the splint 8 in the direction of the rotating rod 12. In order to avoid that the splint 8 is automatically reset due to the elastic force after the rotating disk 10 drives the splint 8 away from the rotating rod 12, a circular plate 15 is fixedly connected to the middle part of the lower end of the rotating rod 12, and a plurality of clamping grooves 17 are opened on the outer wall of the circular plate 15. A symmetrical clamping block 16 is slidably connected to the bottom of the inner cavity of the mounting groove 11, and one end of the clamping block 16 close to the circular plate 15 is clamped in the inner cavity of the clamping groove 17, and the end of the clamping block 16 away from the circular plate 15 is elastically connected to the inner cavity side wall of the mounting groove 11 through a spring, and the side wall and the upper end of the clamping block 16 close to the circular plate 15 are both provided with inclined surfaces, so that when the circular plate 15 rotates clockwise with the rotating rod 12, the clamping groove 17 will engage with the clamping block The inclined surface on the lower side of 16 contacts, thereby pushing the block 16 to move horizontally in the direction away from the circular plate 15. During this process, the block 16 elastically engages the circular plate 15, so that the circular plate 15 can rotate clockwise. When the turntable 10 stops rotating, the splint 8 is subjected to the elastic force toward the position of the turntable 10, and the elastic force drives the splint 8 to reset. At this time, the splint 8 pushes the push rod 19 and the rack 18 to reset, thereby driving the rotating rod 12 to rotate counterclockwise through the gear 13. At this time, the inner cavity of the slot 17 will contact the side wall of the block 16 away from the lower inclined surface. At this time, the inner cavity side wall of the slot 17 and the side wall of the block 16 abut against each other, so that the block 16 will engage and limit the slot 17, thereby avoiding that the splint 8 is immediately reset after the turntable 10 stops rotating clockwise, resulting in insufficient time to place the geological detection radar above the substrate 6.

[0035] See also Figure 5 The lower end of the driven rod 101 is fixedly connected with a symmetrical connecting rod 14, and the connecting rod 14 is slidably connected to the lower part of the inner cavity of the rotating rod 12. The symmetrical connecting rod 14 is fixedly connected with a ring at one end away from the driven rod 101. The diameter of the ring is greater than the diameter of the rotating rod 12. An arc surface is provided on the side of the lower end of the ring away from the rotating rod 12. When the rotating disk 10 drives the driven rod 101 to move downward, the outer wall of the lower end of the ring will approach the position of the block 16. At this time, the arc surface will contact the upper end inclined surface of the block 16, thereby squeezing the block 16 away from the circular plate 15. direction, and then separate from the slot 17, releasing the limiting effect on the circular plate 15 so that the circular plate 15 and the rotating rod 12 can rotate in the counterclockwise direction, so that the symmetrical clamping plate 8 is reset under the action of elastic force, that is, when the geological detection radar is placed on the top of the substrate 6, the lower end face of the geological detection radar will press the turntable 10 downward, thereby driving the circular ring to push the card block 16 away from the inner cavity of the slot 17, so that when the geological detection radar is placed on the upper end face of the substrate 6, the clamping plate 8 will automatically reset and clamp the geological detection radar in position.

[0036] See also Figure 7-8 The upper end of the base plate 6 is fixedly connected with a symmetrical guide plate 20, which is located above the base plate 6 and close to the side of the frame 2. The outer walls of the symmetrical guide plates 20 are slidably connected with a cross plate 7. The lower end of the cross plate 7 is provided with a symmetrical adapting groove 23. The position and size of the adapting groove 23 correspond to the slide groove 9. A reset plate 24 is vertically slidably connected to the middle of the inner cavity of the adapting groove 23. The upper end surface of the reset plate 24 is elastically connected to the top of the inner cavity of the adapting groove 23 through a symmetrical spring. A plurality of slide plates 25 are vertically slidably connected to the lower part of the inner cavity of the adapting groove 23. The plurality of slide plates 25 fit each other and can only move in the vertical direction. The upper end of the slide plate 25 The surface fits with the lower end surface of the reset plate 24. After the symmetrical clamping plates 8 elastically clamp and position the geological detection radar, the cross plate 7 is pressed downward to drive the slide plate 25 close to the position of the clamping plate 8. After the clamping plate 8 contacts the slide plate 25 corresponding to its position, it will relatively push the slide plate 25 of this part to move upward. At this time, the reset plate 24 will also be lifted up by the upward slide plate 25, and the remaining slide plates 25 will remain in the initial position and limit the clamping plate 8 in the horizontal direction, so as to avoid the clamping plate 8 from shaking due to bumps during the movement of the measuring vehicle, which will cause the geological detection radar to detach from the top of the base plate 6 due to the bumps of the measuring vehicle.

[0037] See also Figure 9-10In order to place the geological detection radar before the upper end surface of the substrate 6, the cross plate 7 keeps a position away from the substrate 6, so a plurality of symmetrical positioning grooves 21 are provided on the side wall of the guide plate 20, and a positioning rod 28 is slidably connected to the inner cavity of the side of the cross plate 7 close to the guide plate 20, and the positioning rod 28 is snap-fitted with the positioning groove 21, and the side of the positioning rod 28 away from the guide plate 20 is elastically connected to the inner cavity of the cross plate 7 through a spring, and a fixing rod 29 is fixedly connected to the middle of the end of the positioning rod 28 away from the guide plate 20, and a slider 30 is fixedly connected to the symmetrical fixing rods 29 at one end away from the guide plate 20, and a through groove 26 is provided in the middle of the upper end of the cross plate 7, and a touch rod 22 is vertically slidably connected to the bottom of the inner cavity of the through groove 26, and a T-shaped circular plate 31 is vertically slidably connected to the upper end of the touch rod 22, and the T-shaped circular plate The upper end surface of the T-shaped circular plate 31 is elastically connected to the top of the inner cavity of the through groove 26 by a spring. The spring makes the touch rod 22 located at the top of the inner cavity of the through groove 26, and also makes the T-shaped circular plate 31 and the touch rod 22 fit each other. There is a gap between the T-shaped circular plate 31 and the touch rod 22. When the lower end surface of the touch rod 22 and the top of the driving rod 33 are lower than the lower end surface of the slider 30, the T-shaped circular plate 31 will not affect the movement state of the slider 30. When the cross plate 7 is pressed at this time, the positioning rod 28 and the positioning groove 21 are elastically engaged, that is, the engagement of the positioning rod 28 and the positioning groove 21 will not affect the movement state of the cross plate 7, and the cross plate 7 can be kept at a certain height.

[0038] After the geological detection radar is clamped by the clamping plate 8, pressing the cross plate 7 downward can make the upper end of the clamping plate 8 enter the inner cavity of the adapter groove 23 and engage with the slide plate 25, thereby limiting the horizontal position of the clamping plate 8. When the lower end surface of the cross plate 7 approaches the geological detection radar, the feeler rod 22 will be relatively squeezed and moved upward by the geological detection radar, thereby driving the T-shaped circular plate 31 to move upward synchronously, and when the lower end surface of the cross plate 7 is in contact with the upper end surface of the geological detection radar, the outer wall of the T-shaped circular plate 31 contacts the end of the slider 30 away from the fixed rod 29, thereby limiting the movement of the positioning rod 28, the fixed rod 29 and the slider 30, so that the positioning rod 28 and the positioning groove 21 are fixedly engaged, so that the position of the cross plate 7 in the vertical direction is fixed, and the geological detection radar is further limited in the vertical direction, so that during the movement of the measuring vehicle, even if the vehicle body itself occurs The position of the geological detection radar can also be stably fixed when the vehicle is bumpy. There is no need to worry that the geological detection radar will be detached from the top of the substrate 6 due to the vibration caused by the bumps when the vehicle moves quickly. When the geological detection radar needs to be disassembled, pull the traction rod 27 upward to drive the T-shaped circular plate 31 to move up. At this time, the outside of the T-shaped circular plate 31 is separated from the slider 30, that is, the positioning rod 28, the fixing rod 29 and the slider 30 restore the ability to move in the horizontal direction. At this time, continue to pull the traction rod 27 to make the cross plate 7 away from the position of the substrate 6, and then separate the slide plate 25 from the splint 8. After the slide plate 25 is separated from the splint 8, the reset plate 24 will push the slide plate 25 to reset under the action of elastic force. After the cross plate 7 is separated from the geological detection radar, pull the geological detection radar upward to separate it from the substrate 6, thereby completing the disassembly.

[0039] See also Figure 3 In the process of detection by the survey vehicle equipped with geological detection radar, with the continuous movement of the survey vehicle, bumps and vibrations are inevitable, and excessive vibrations will cause the electromagnetic waves emitted by the geological radar to scatter and reflect, thereby affecting the accuracy of the data. Therefore, in order to ensure the accuracy of the detection results of the geological detection radar, the shock absorption of the survey vehicle is necessary. In order to reduce the vibration of the geological detection radar caused by the survey vehicle when it moves, elastic components such as springs are usually provided to reduce the vibration. Symmetrical fixing plates 5 are fixedly connected to the four corners of the inner cavity of the frame 1, and elastic rods 3 are fixedly connected between the symmetrical fixing plates 5. The substrate 6 is slidably matched with the outer wall of the elastic rod 3. The fixing plate 5 and the substrate 6 are elastically connected by a spring, and the spring is sleeved on the outer wall of the elastic rod 3. That is, the vibration generated by the survey vehicle will be transmitted to the substrate 6, and the substrate 6 will be offset in the vertical or horizontal direction due to the vibration, and the vibration is offset by the deformation of the spring and the elastic rod 3, and the geological detection radar will be offset synchronously with the substrate 6, thereby reducing the vibration of the geological detection radar during the movement of the survey vehicle.

[0040] See also Figure 11-12The vibration of the geological detection radar can be reduced by the elastic component, but when fixing the geological detection radar, the substrate 6 will inevitably be subjected to external force. For example, when placing the radar, one side of the radar first contacts the substrate 6, and then the radar is pushed to move on the upper end surface of the substrate 6. External force will be applied to the substrate 6, which will cause the substrate 6 to deviate, resulting in the need to apply additional force to keep the substrate 6 stable when fixing the radar, thereby complicating the fixing process of the radar. In order to avoid this situation, in this solution, a rod 34 is provided in the middle part of the inner cavity of the slide groove 9, and the outer wall of the rod 34 is slidably connected to the inner cavity of the substrate 6, and the outer wall of the rod 34 is slidably connected to the middle part of the lower side of the splint 8. Then, a groove 32 is provided in the middle part of the side of the splint 8 close to the rotating rod 12, and a driving rod 33 is rotatably connected to the inner cavity of the groove 32 close to the rotating rod 12. The side of the upper end of the driving rod 33 away from the rotating rod 12 is elastically connected to the inner cavity side wall of the groove 32 by a spring. The spring makes the upper end of the driving rod 33 located outside the groove 32, and when the upper end of the driving rod 33 is located outside the groove 32, the lower end of the driving rod 33 is higher than the upper end of the insertion rod 34, and a driven block 35 is fixedly connected to the middle part of the upper end of the insertion rod 34, and in the process of the splint 8 driving the driving rod 33 away from the rotating rod 12, the lower end of the driving rod 33 is always higher than the upper end of the insertion rod 34, so the driving rod 33 will not contact the driven block 35.

[0041] When the clamping plate 8 approaches the geological detection radar and contacts it, the upper end of the driving rod 33 will rotate relative to the inner cavity of the groove 32 after contacting the radar. At this time, the lower end of the driving rod 33 will contact the driven block 35 during the rotation process, pushing the driven block 35 to move toward the position of the rotating rod 12, thereby driving the insertion rod 34 to move horizontally toward the position of the rotating rod 12. The end of the insertion rod 34 close to the rotating rod 12 is elastically connected to the inner cavity side wall of the substrate 6 through a spring. A slot 36 that is engaged with the insertion rod 34 is provided in the middle of the inner cavity of the frame 1. When the driving rod 33 does not rotate, the insertion rod 34 and the driven block 35 maintain their initial The initial position, that is, the insertion rod 34 is clamped in the slot 36, so that the substrate 6 is clamped and fixed to the frame 1 through the insertion rod 34, so that when the geological detection radar is placed on the substrate 6, the substrate 6 will not be offset due to the contact with the geological detection radar. The insertion rod 34 will not be separated from the slot 36 until the splint 8 is in close contact with the geological detection radar, so that the substrate 6 and the frame 1 can maintain independent movement states. That is, after the splint 8 fixes the radar, the shock-absorbing effect of the elastic rod 3 and the spring will be reflected, which is convenient for fixing the radar, and also reduces the vibration of the radar when it moves with the measuring vehicle.
