[0025] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0026] Reference Figure 1-5 As shown, a stable and intelligent dual-axis turntable for radar includes a bottom plate 1, two first side plates 2 are fixedly installed on the upper surface of the bottom plate 1, and the two first side plates 2 are symmetrically distributed about the center line of the bottom plate 1. A circular plate 3 is arranged between the two first side plates 2, and a rotating shaft 4 is fixedly installed on the outer surface of the circular plate 3 corresponding to the two first side plates 2. The rotating shaft 4 is externally connected to a power source, and the rotating shaft 4 is rotatably connected to the two first side plates 2. A buffer component 5 is arranged above the circular plate 3, and a fixed plate 501 and a top plate 504 are arranged inside the buffer component 5. The fixed plate 501 It is connected to the circular plate 3 through a connecting rod, and the connecting rod is connected to an external power source. A plurality of fixing components 6 are fixedly installed on the upper surface of the top plate 504, and the plurality of fixing components 6 are distributed circumferentially about the center line of the top plate 504. The staff aligns the holes of the radar base with the fixing components 6, and the staff can quickly disassemble and assemble the radar through the fixing components 6. When the radar is fixed to the surface of the top plate 504, the buffer component 5 buffers the radar to prevent the radar from being damaged due to rigid impact during installation. The connecting rod and the rotating shaft 4 realize dual-axis control of the radar.

[0027] like Figure 2 As shown, the outer surface of the base plate 1 is sleeved with a protective tube 7, and through grooves 8 are formed all around the protective tube 7. A rack 9 is fixedly installed on the inner wall of the through groove 8. A gear 10 is arranged under the base plate 1 corresponding to the rack 9, and the gear 10 is meshed and connected with the rack 9. The gear 10 is connected to an external power source. Support plates 11 are arranged on both sides of the gear 10. The two support plates 11 are rotatably connected to the gear 10, and the support plates 11 are fixedly connected to the bottom surface of the base plate 1. The gear 10 rotates to make the base plate 1 move up and down as a whole along the edge direction of the rack 9. The protective tube 7 provides a solid outer protective shell for the entire turntable, which not only enhances the overall structural strength of the turntable, but also improves its ability to resist external shocks and vibrations.

[0028] like Figure 2-3As shown, a fixing rod 12 is arranged between the support plate 11 and the inner wall of the through groove 8, one end of the fixing rod 12 is rotatably connected to the support plate 11, a first connecting plate 13 is fixedly installed on the bottom surface of the bottom plate 1 corresponding to the fixing rod 12, a first rotating rod 14 is rotatably installed inside the first connecting plate 13, second side plates 15 are fixedly installed at both ends of the rotating rod, a second connecting plate 16 is fixedly installed on the side of the second side plate 15 away from the rotating rod, an electric push rod 17 is fixedly installed on the side of the second connecting plate 16 away from the first connecting plate 13, a third connecting plate 18 is fixedly installed on one end of the electric push rod 17 away from the second connecting plate 16, third side plates 19 are fixedly installed on both sides of the third connecting plate 18, and the two third side plates 19 A second rotating rod 20 is fixedly installed therebetween, and a fourth connecting plate 21 corresponding to the third side plate 19 is sleeved on the outer surface of the second rotating rod 20, and the fourth connecting plate 21 is fixedly connected to the side surface of the fixing rod 12. When the position of the base plate 1 is fixed, the components of the base plate 1 exert pressure on the fixing rod 12 under the action of gravity. Since the other end of the fixing rod 12 abuts against the inner wall of the tooth groove in the rack 9, the fixing rod 12, the rack 9 and the base plate 1 form a triangle, so that the base plate 1 is fixed in a suitable position. When the base plate 1 needs to move, the gear 10 first rotates upward to disengage the fixing rod 12 from the tooth groove, and at the same time the electric push rod 17 contracts to make the fixing rod 12 away from the tooth groove, and the gear 10 moves the base plate 1 to a suitable position by rotating.

[0029] like Figure 4 As shown, the buffer assembly 5 includes a fixed plate 501, the upper surface of the fixed plate 501 is provided with a groove 502, and a plurality of pneumatic telescopic rods 503 are fixedly installed inside the groove 502, and the plurality of pneumatic telescopic rods 503 are evenly distributed about the bottom of the inner wall of the groove 502, and a top plate 504 corresponding to the groove 502 is arranged above the fixed plate 501, and the top plate 504 is fixedly connected to the ends of the plurality of pneumatic telescopic rods 503, and the outer surface of the pneumatic telescopic rod 503 is sleeved with a first spring 505, and the two ends of the first spring 505 are respectively fixedly connected to the inner wall of the groove 502 and the bottom surface of the top plate 504. When the radar is placed in the device Under the action of gravity, the radar applies pressure to the top plate 504, and the top plate 504 pushes the pneumatic telescopic rod 503 to contract. At the same time, the first spring 505 is deformed to provide buffering. The first spring 505 can absorb and store energy. When the radar is taken out, the first spring 505 releases the stored energy to help the top plate 504 return to its original position. At the same time, the pneumatic telescopic rod 503 not only has a buffering effect, but can also be telescopically adjusted through pneumatic control. When necessary, the height and position of the top plate 504 can be fine-tuned by adjusting the telescopic amount of the pneumatic telescopic rod 503, thereby meeting the needs of radar equipment in different working environments.

[0030] like Figure 5As shown, the fixing assembly 6 includes a round rod 601, a plurality of movable grooves 602 are provided inside the round rod 601, and the plurality of movable grooves 602 are distributed circumferentially about the center line of the round rod 601, a guide rod 603 is fixedly installed on the inner wall of the movable groove 602, a movable plate 604 is provided inside the movable groove 602, a limiting plate 605 is provided on the side of the movable plate 604 away from the guide rod 603, a second spring 606 is sleeved on the outer surface of the guide rod 603, and the two ends of the second spring 606 are respectively fixedly connected to the inner wall of the movable groove 602 and the side of the movable plate 604, after the round rod 601 enters the hole in the radar base, the radar base squeezes the limiting plate 605 along the surface of the limiting plate 605, so that the limiting plate 605 shrinks into the movable groove 602, and after the base moves to below the limiting plate 605, the second spring 606 pushes the limiting plate 605 on the movable plate 604 to quickly reset, thereby realizing the fixing of the limiting plate 605 to the bottom plate 1.

[0031] like Figure 5 As shown, the shape of the limit plate 605 is a truncated cone, and the outer surface of the limit plate 605 is provided with rounded corners. The limit plate 605 adopts a truncated cone design, which can more effectively disperse the pressure generated by the radar equipment during the fixing process. When the radar equipment is fixed in the fixing component 6, the limit plate 605 serves as a direct contact point, and its truncated cone design enables the pressure to be more evenly distributed over a larger contact area, thereby avoiding damage or deformation of the equipment caused by excessive local pressure. At the same time, the truncated cone shape makes it easier for the radar base to apply thrust to the limit plate 605. The rounded corner design of the outer surface of the limit plate 605 greatly reduces the stress concentration phenomenon when in contact with the radar equipment. The rounded corner can smoothly transition the contact force and avoid scratches or indentations that may be caused by sharp edges, thereby protecting the integrity and appearance of the radar equipment.

[0032] like Figure 5 As shown, a plurality of slide grooves 607 are provided on the outer surface of the round rod 601 corresponding to the movable groove 602, and the plurality of slide grooves 607 are distributed circumferentially about the center line of the round rod 601. A sleeve 608 is sleeved on the outer surface of the round rod 601, and a slide plate 609 corresponding to the slide groove 607 is fixedly installed on the inner wall of the sleeve 608. A guide rod 610 is fixedly installed on the inner wall of the movable groove 602, and the guide rod 610 is slidably connected with the slide plate 609. A third spring 611 is sleeved on the outer surface of the guide rod 610, and two ends of the third spring 611 are respectively fixedly connected with the inner wall of the movable groove 602 and the surface of the slide plate 609. When removing quickly, the staff pushes the sleeve 608 downward, and the sleeve 608 contracts the limiting plate 605. The staff can quickly remove the radar by using tools, and then the third spring 611 pushes the slide plate 609 to reset.

[0033] like Figure 4As shown, a circular ring 22 is fixedly installed on the upper surface of the top plate 504 corresponding to the fixing assembly 6, and the axis of the circular ring 22 coincides with the axis of the round rod 601. After the radar base enters the limiting plate 605, the staff fine-tunes the radar base so that the axis of the circular ring 22 coincides with the axis of the hole of the radar base. The circular ring 22 limits the horizontal direction of the radar base and facilitates the rapid removal of the radar base.

[0034] like Figure 4 As shown, a buffer plate 23 is fixedly installed on the upper surface of the top plate 504. The buffer plate 23 serves as a direct contact layer between the top plate 504 and the radar equipment, and can further absorb and disperse the vibration and impact force encountered by the radar equipment during operation. It works together with the top plate 504 and the buffer component 5 below to form a multi-layer shock absorbing system, which further improves the seismic performance of the radar equipment. The buffer plate 23 has a certain elasticity and flexibility and can fit tightly to the bottom surface of the radar equipment. Even on an uneven installation surface or one with slight differences, it can ensure a stable connection between the radar equipment and the top plate 504.

[0035] A method for using a stable and intelligent dual-axis turntable for radar comprises the following steps: S1: When the base plate 1 is raised or lowered, the gear 10 rotates to move the base plate 1 as a whole along the edge direction of the rack 9. When the gear 10 moves to a suitable position, the electric push rod 17 unfolds to allow one end of the fixed rod 12 to enter the tooth groove.

[0036] S3: After the gear 10 stops rotating, the bottom plate 1 applies pressure to the fixing rod 12 under the action of gravity, and the fixing rod 12, the rack 9 and the bottom plate 1 form a triangle, so that the bottom plate 1 is fixed in a suitable position.

[0037] S4: When the bottom plate 1 needs to move downward, the gear 10 first rotates upward to disengage the fixing rod 12 from the tooth groove, and at the same time the electric push rod 17 contracts to move the fixing rod 12 away from the tooth groove, and the gear 10 rotates to move the bottom plate 1.

[0038] S5: When fixing the radar, after the round rod 601 enters the hole in the radar base, the radar base presses the limiting plate 605 along the surface of the limiting plate 605 , so that the limiting plate 605 shrinks into the moving groove 602 .

[0039] S6: After the base moves to below the limiting plate 605 , the second spring 606 pushes the limiting plate 605 on the movable plate 604 to quickly reset, thereby fixing the limiting plate 605 to the bottom plate 1 .

[0040] S7: Fine-tune the radar base according to the ring 22 to ensure that the axis of the ring 22 coincides with the axis of the hole of the radar base.

[0041] S8: When removing the radar, the staff pushes the sleeve 608 downward, and the sleeve 608 contracts the limiting plate 605. The staff can quickly remove the radar using tools, and then the third spring 611 pushes the slide plate 609 to return to its original position.

[0042] Working principle: When the bottom plate 1 is raised or lowered, the gear 10 rotates to move the bottom plate 1 as a whole along the edge direction of the rack 9. When the gear 10 moves to a suitable position, the electric push rod 17 expands to allow one end of the fixed rod 12 to enter the tooth groove. After the gear 10 stops rotating, the bottom plate 1 applies pressure to the fixed rod 12 under the action of gravity. The fixed rod 12, the rack 9 and the bottom plate 1 form a triangle, so that the bottom plate 1 is fixed in a suitable position. When the bottom plate 1 needs to move downward, the gear 10 first rotates upward to disengage the fixed rod 12 from the tooth groove. At the same time, the electric push rod 17 contracts to make the fixed rod 12 away from the tooth groove. The gear 10 rotates to move the bottom plate 1; when fixing the radar, the round rod 60 After entering the hole in the radar base, the radar base presses the limiting plate 605 along the surface of the limiting plate 605, so that the limiting plate 605 shrinks into the moving groove 602. After the base moves to the bottom of the limiting plate 605, the second spring 606 pushes the limiting plate 605 on the moving plate 604 to quickly reset, thereby fixing the limiting plate 605 to the bottom plate 1, and fine-tuning the radar base according to the ring 22 to ensure that the axis of the ring 22 coincides with the axis of the hole in the radar base. When removing the radar, the staff pushes the sleeve 608 downward, and the sleeve 608 shrinks the limiting plate 605. The staff can quickly remove the radar by using tools, and then the third spring 611 pushes the slide plate 609 to reset.

9. The stable and intelligent dual-axis turntable for radar according to claim 2, characterized in that: A buffer plate (23) is fixedly mounted on the upper surface of the top plate (504).

10. A method for using a stable and intelligent dual-axis turntable for radar, used to implement a stable and intelligent dual-axis turntable for radar as claimed in claims 1-9, characterized in that: include: S1: When the base plate (1) is raised or lowered, the gear (10) rotates so that the base plate (1) as a whole moves along the edge direction of the rack (9). When the gear (10) moves to a suitable position, the electric push rod (17) unfolds so that one end of the fixed rod (12) enters the tooth groove; S3: After the gear (10) stops rotating, the bottom plate (1) exerts pressure on the fixed rod (12) under the action of gravity, and the fixed rod (12), the rack (9) and the bottom plate (1) form a triangle, so that the bottom plate (1) is fixed in a suitable position; S4: When the bottom plate (1) needs to move downward, the gear (10) first rotates upward, causing the fixing rod (12) to disengage from the tooth groove. At the same time, the electric push rod (17) contracts, causing the fixing rod (12) to move away from the tooth groove. The gear (10) rotates to move the bottom plate (1); S5: When fixing the radar, after the round rod (601) enters the hole in the radar base, the radar base presses the limiting plate (605) along the surface of the limiting plate (605), so that the limiting plate (605) shrinks into the moving groove (602); S6: After the base moves to below the limiting plate (605), the second spring (606) pushes the upper limiting plate (605) of the movable plate (604) to quickly reset, thereby achieving the fixing of the limiting plate (605) to the bottom plate (1); S7: fine-tune the radar base according to the ring (22) to ensure that the axis of the ring (22) coincides with the axis of the hole in the radar base; S8: When removing the radar, the staff pushes the sleeve (608) downward, and the sleeve (608) contracts the limiting plate (605). The staff can quickly remove the radar by using a tool, and then the third spring (611) pushes the slide plate (609) to reset.
