Description

Technical Field

[0001] This invention belongs to the field of surveying and mapping devices, and specifically relates to a remote sensing and mapping device. Background Technology

[0002] Infrared remote sensing operates primarily in the wavelength range of 0.76–15.0 micrometers. It acquires infrared images through infrared sensing elements, and the main sensors include multispectral infrared scanners, infrared thermal imagers, and single-channel infrared radiometers.

[0003] The aforementioned multispectral infrared scanners and infrared thermal imagers are all mounted on tripods. For example, Chinese patent CN219453425U discloses an easily detachable and detachable 3D scanner assembly. This patent includes two sets of detachment / assembly components. When fixing the 3D scanner to the tripod using these components, during installation, a long rod needs to be rotated to overcome the torsion spring's torque, allowing the locking block to pass through the corresponding second limiting groove. Then, the long rod is released, and under the torsion of the torsion spring, the locking block engages with the upper surface of the first limiting block. Disassembly is the reverse process.

[0004] The patent includes two sets of disassembly and assembly components to increase the stability of the 3D scanner fixed on the tripod. If only a single disassembly and assembly component is used, the 3D scanner can rotate freely around the axis of the long rod of the single disassembly and assembly component, which will cause the 3D scanner to be loosely connected to the tripod.

[0005] However, because two disassembly and assembly components are set up, and the operator must operate the disassembly and assembly components simultaneously, when operating the two sets of disassembly and assembly components, the operator can only operate one disassembly and assembly component with one hand (i.e., rotate the long rod of one disassembly and assembly component with one hand). The two disassembly and assembly components require the operator to operate both hands at the same time. A single operator cannot completely detach the 3D scanner from the tripod. Two operators are required to work together to complete the disassembly and assembly of the 3D scanner using the patented disassembly and assembly components. This results in a waste of manpower and inconvenience in disassembly and assembly. Summary of the Invention

[0006] The present invention provides a remote sensing mapping device that, while possessing robust connection capabilities, allows for assembly and disassembly by a single operator.

[0007] To achieve the above objectives, the present invention provides a remote sensing mapping device, comprising a tripod assembly, characterized in that it further comprises a mounting plate, wherein the mounting plate has a vertically extending anti-mistake insertion hole penetrating the mounting plate, and an anti-mistake insertion rod is fixed to the outer shell of the remote sensing mapping instrument, the anti-mistake insertion rod being inserted into the anti-mistake insertion hole; a connecting plate is fixed to the lower end of the mounting plate, and a through hole is vertically extending through the connecting plate, the lower end of the anti-mistake insertion rod being inserted into the through hole; the axis of the through hole coincides with the axis of the anti-mistake insertion rod; and a [missing information - likely a design feature] is provided in the through hole. There are multiple limiting components, which are arranged in a circumferential array along the axis of the foolproof plug. Each limiting component includes: a limiting frame, which can slide radially along the foolproof plug and is a rectangular frame; located on the outside of the foolproof plug; the perpendicular bisector of the long side 'a' of the limiting frame passes through the center of the foolproof plug; a limiting rod, which is fixed to the side wall of the limiting frame closest to the foolproof plug; and a return spring, one end of which is fixed to the inner wall of the through hole, and the other end of which is fixedly connected to the side wall of the limiting frame away from the foolproof plug; the return spring is always in a compressed state. A limiting hole is formed on the peripheral wall of the foolproof rod; under the elastic force of the return spring, the return spring inserts the end of the limiting rod into the limiting hole through the limiting frame; it also includes an unlocking assembly, which includes: multiple unlocking posts with their axes parallel to the axis of the foolproof rod; the unlocking posts are set one-to-one with the limiting frame; the unlocking posts are located in the limiting frame and can move relative to the unlocking posts, with the peripheral wall of the unlocking posts abutting against the inner side wall of the limiting frame; each unlocking post is arranged in a circumferential array along the axis of the foolproof rod; a driven plate is rotatably connected to the inner wall of the through hole, and the axis of rotation of the driven plate coincides with the axis of the foolproof rod; each unlocking post is fixedly connected to the upper surface wall of the driven plate, and the mounting plate is connected to the tripod assembly through a height adjustment assembly, and neither the mounting plate nor the driven plate contacts the tripod assembly.

[0008] Furthermore, the tripod assembly includes: a fixed base, horizontally arranged; multiple connecting rods, arranged in a circumferential array along the axis of the fixed base; the upper end of the connecting rod is hinged to the peripheral wall of the fixed base; and multiple sleeves, corresponding one-to-one with the connecting rods, and sleeved on the lower end of the connecting rods.

[0009] It serves a leveling function, allowing remote sensing and mapping instruments to be placed even in complex terrains.

[0010] Furthermore, the height adjustment assembly includes: a long screw threadedly connected to the fixed base, with its axis arranged vertically and its upper end rotatably connected to the mounting plate; and a guide rod with its axis arranged vertically, passing through the fixed base, capable of moving vertically relative to the fixed base, and its upper end fixed to the mounting plate.

[0011] It not only serves to adjust the height of instruments used for remote sensing mapping, but also ensures that there is always a certain gap between the lower end of the mounting plate and the upper end of the fixed base, so that the user can easily rotate the driven plate.

[0012] Furthermore, the surveying device also includes a shielding assembly, which comprises: two baffles rotatably connected to the mounting plate, the two baffles being symmetrically arranged along the vertical plane passing through the center of the remote sensing surveying instrument lens and perpendicular to the lens; a slot, formed on the side wall of the mounting plate; a locking plate, movably locked in the slot, the locking plate being able to move vertically relative to the slot; two locking rods, both fixed to the upper end of the locking plate, the axes of the locking rods being arranged vertically; two connecting slots, corresponding one-to-one with the locking rods, formed on the upper surface wall of the slot, the locking rods being able to be inserted into the connecting slots accordingly; the upper end of the connecting slot extends to the upper surface wall of the mounting plate, the upper end of the locking rod can protrude through the connecting slot; a limiting spring, located in the slot, one end fixedly connected to the lower end of the locking plate, the other end fixedly connected to the bottom wall of the slot; the limiting spring is always in a compressed state; two locking holes, corresponding one-to-one with the connecting slots, respectively formed on the corresponding two baffles; the portion of the locking rod protruding from the connecting slot can be inserted into the locking hole.

[0013] By using a shielding component, the lens of the remote sensing and mapping instrument can be shielded. When the lens of the remote sensing and mapping instrument is not in use, the shielding component can provide a certain degree of protection for the lens.

[0014] Furthermore, a turntable is fixed to the lower end of the driven plate, and the axis of the turntable coincides with the axis of the driven plate.

[0015] The driven plate is rotated by a turntable, making it more convenient to use.

[0016] Furthermore, both the driven plate and the turntable are transparent.

[0017] Through the transparent driven plate and turntable, the position of the limit rod in the through hole can be directly observed, making it convenient for the operator to observe whether the limit rod has disengaged from the limit hole.

[0018] Furthermore, when the lower end of the anti-foolproof plug abuts against the upper end of the driven plate, the axis of the limiting hole coincides with the axis of the corresponding limiting rod.

[0019] The anti-foolproof plug acts as a limiter for the downward travel of the plug. As long as the anti-foolproof plug touches the upper surface of the driven plate, the limit rod can be inserted into the limit hole. The operator no longer needs to observe the position of the anti-foolproof plug or make the axis of the limit hole coincide with the axis of the limit rod. Beneficial effects

[0020] 1. In use, the operator rotates the turntable with one hand while inserting the foolproof locking rod from the remote sensing and mapping instrument into the foolproof locking hole with the other hand. When the axis of the limiting hole and the limiting rod aligns, the turntable is released. Under the action of the return spring, the limiting rod engages with the limiting hole, completing the installation operation. Conversely, rotating the turntable pulls the foolproof locking rod out of the foolproof locking hole, completing the disassembly operation. The entire process requires only one operator using both hands simultaneously.

[0021] In existing patents, both disassembly and assembly components require the operator to use both hands simultaneously, leaving no extra hand for detaching the 3D scanner from the tripod. Therefore, existing patents require at least two operators working together. This solution, therefore, saves manpower during disassembly and assembly. 2. This solution connects the mounting plate to the foolproof insertion rod by having four limiting components simultaneously engage with the limiting holes of the foolproof insertion rod; existing patents rely on two disassembly and assembly components. In terms of sheer quantity, this solution does not reduce the connection's strength. In summary, this solution facilitates disassembly and installation without compromising strength.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] See Figure 1 A remote sensing mapping device includes a tripod assembly, the tripod assembly comprising: Fixing base 1 is horizontally arranged; in this embodiment, fixing base 1 is a disc. Multiple support legs are hinged to the peripheral wall of the fixed base 1. Each support leg is arranged in a circular array around the axis of the disk, and the axis of rotation of the support leg is set in the horizontal direction.

[0026] The support leg includes a connecting rod 2, the upper end of which is hinged to the peripheral wall of the fixed base 1; a sleeve 3 is fitted on the connecting rod 2, the upper end of which is fitted on the lower end of the connecting rod 2, and the lower end of the sleeve abuts against the ground. The sleeve 3 can slide along the length of the connecting rod 2. After the sleeve 3 slides to a suitable position, it is fixedly connected to the connecting rod with bolts.

[0027] A mounting plate 4 is provided above the fixed base 1. The mounting plate 4 is horizontally positioned and does not contact the fixed base 1. A foolproof insertion hole is vertically formed along the upper edge of the mounting plate 4. The axis of the foolproof insertion hole is vertically aligned and passes through the mounting plate 4. A foolproof insertion rod 6 is fixed to the lower end of the housing of the remote sensing and mapping instrument 5 (one of a multispectral infrared scanner or an infrared thermal imager, etc.). The axis of the foolproof insertion rod 6 is vertically aligned and engages with the foolproof insertion hole. The remote sensing and mapping instrument 5, along with the foolproof insertion rod 6, cannot rotate around the axis of the foolproof insertion hole. The foolproof insertion hole consists of a protrusion on its side wall, and a groove on the foolproof insertion rod 6 that mates with the protrusion. The foolproof insertion rod 6 can only be inserted into the foolproof insertion hole at a specific angle; at other angles, the foolproof insertion rod 6 cannot be inserted into the foolproof insertion hole.

[0028] See Figure 1 and Figure 2A connecting plate 7 is fixed to the lower surface of the mounting plate 4. The connecting plate 7 has a vertically oriented through hole 8 that penetrates the connecting plate 7. The axis of the through hole 8 coincides with the axis of the anti-foolproof insertion hole. In this embodiment, the through hole 8 is circular when viewed along the axis of the anti-foolproof insertion hole, and the lower end of the aforementioned anti-foolproof rod 6 is inserted into the through hole 8. Four limiting blocks 9 are fixed to the inner wall of the through hole 8, arranged in a circumferential array along the axis of the through hole 8. A set of limiting components is provided between two adjacent limiting blocks 9 when viewed along the axis of the through hole 8, for a total of four sets of limiting components, used to prevent the anti-foolproof rod 6 from detaching from the anti-foolproof insertion hole and the through hole 8; each limiting component is arranged in a circumferential array along the axis of the through hole 8, and the limiting components include: The limiting frame 10 is movably mounted on two adjacent limiting blocks 9 and can slide along the limiting blocks 9 in the radial direction of the anti-foolproof rod 6. In this embodiment, the limiting frame 10 is a rectangular frame when viewed along the axis of the through hole 8. The limiting frame 10 is located outside the anti-foolproof rod 6. Let the long side of the limiting frame 10 be a, and the perpendicular bisector of the long side a passes through the center of the anti-foolproof rod 6.

[0029] The axis of the limiting rod 11, when viewed along the axis of the through hole 8, coincides with the perpendicular bisector of the long side a. The limiting rod 11 is fixed on the limiting frame 10, and the limiting rod 11 is located on the side wall of the limiting frame 10 near the anti-foolproof insert 6.

[0030] The return spring 12 is fixed at one end to the inner wall of the through hole 8 and at the other end to the outer wall of the limiting frame 10 away from the anti-fooling rod 6. The return spring 12 is always in a compressed state. The return spring 12 applies force to the limiting frame 10 and the limiting rod 11, causing the limiting rod 11 to move closer to the anti-fooling rod 6. The direction of the force is parallel to the axis of the limiting rod 11. Four limiting holes are provided on the peripheral wall of the anti-foolproof insertion rod 6. The axis of each limiting hole coincides with the axis of the corresponding limiting rod 11. Under the elastic force of the return spring 12, the ends of multiple limiting rods 11 are inserted into the corresponding limiting holes.

[0031] See Figure 2 , Figure 3 and Figure 5 It also includes an unlocking assembly for disengaging the limiting rod 11 from the limiting hole, the unlocking assembly comprising: Multiple unlocking posts 14 are arranged one-to-one with the limiting frame 10. The axis of the unlocking post 14 is parallel to the axis of the foolproof rod 6. In this embodiment, there are four unlocking posts 14, which are respectively inserted into the limiting frame 10. The unlocking post 14 can move relative to the limiting frame 10 along the long side a of the limiting frame 10, and the peripheral wall of the unlocking post 14 abuts against the inner surface wall of the limiting frame 10. The unlocking posts 14 are arranged in an array along the axis of the foolproof rod 6. Figure 2In the initial state (in this state, the limit frame 10 moves to the end of the limit block 9 under the action of the reset spring 12 and cannot continue to move towards the anti-foolproof plug 6), at this time, each unlocking post 14 is located at the end of the long side of the limit, and the limit rod 11 is inserted into the corresponding limit hole.

[0032] The driven plate 15, in this embodiment, is a circular plate. Its peripheral wall is rotatably connected to the peripheral wall of the through hole 8, and the axis of rotation of the driven plate 15 coincides with the axis of the through hole 8. The lower surface of the anti-fooling rod 6 abuts against the upper surface of the driven plate 15. Only when the lower surface of the anti-fooling rod 6 abuts against the upper surface of the driven plate 15 does it indicate that the anti-fooling rod 6 is fully inserted into the anti-fooling hole, and only then can the aforementioned limiting component be used. All the aforementioned unlocking pins 14 are fixed to the upper surface of the driven plate 15.

[0033] A turntable 16 is fixed to the lower surface wall of the driven plate 15. In this embodiment, the turntable 16 is a disc, and its axis coincides with the axis of the driven plate 15. The turntable 16 is located outside the through hole 8 and is used by the operator to rotate it, thereby causing the driven plate 15 and all the unlocking pins 14 to rotate around the axis of the turntable 16. The turntable 16 is located above the fixed base 1, and it does not abut against the surface wall of the fixed base 1, leaving a gap to facilitate the operator's rotation of the turntable 16.

[0034] Will Figure 2 Viewed along the axis of the foolproof locking rod 6, if the user rotates the turntable 16, the driven plate 15 will rotate with the turntable 16, and then the four unlocking pins 14 will also rotate with the driven plate 15. Specifically, with Figure 2 The unlocking post 14, as shown in the diagram, is the initial point X. During the user's clockwise rotation of the dial 16 (i.e., as the unlocking post 14 moves from the left end of the limiting frame 10 towards the center point G of the limiting frame 10), since the limiting frame 10 is a rectangle... Figure 2 In this case, the distance from the central position point G in the rectangular frame to the axis of the anti-foolproof rod 6 is less than the distance from the initial point X to the axis of the anti-foolproof rod 6. However, during the rotation of the unlocking post 14, the distance between the initial block and the anti-foolproof rod 6 must always remain a constant value (i.e., the distance from the initial point X of the unlocking post 14 to the axis of the anti-foolproof rod 6). Therefore, during the rotation of each unlocking post 14, the return spring 12 will be compressed through the limit frame 10, and finally the limit rod 11 will disengage from the limit hole on the anti-foolproof rod 6.

[0035] See Figure 1 and Figure 3 It also includes a height adjustment assembly for adjusting the height of the instrument 5 used for remote sensing mapping relative to the tripod, the height adjustment assembly including: The guide rod 17 is vertically oriented and passes through the fixed base 1. The upper end of the guide rod 17 is fixed to the mounting plate 4. The guide rod 17 can move relative to the fixed base 1. The long screw 18 has its axis set vertically and is threadedly connected to the fixed base 1. The upper end of the long screw 18 is rotatably connected to the mounting plate 4.

[0036] When users adjust the height, they only need to rotate the long screw 18, and the mounting plate 4, guide rod 17, and remote sensing and mapping instrument 5 connected to the mounting plate 4 can all be raised or lowered.

[0037] See Figure 1 and Figure 4 It also includes a shielding assembly for shielding the lens of instrument 5 used for remote sensing mapping, the shielding assembly including: Two baffles 19 are rotatably connected to the mounting plate 4; the two baffles 19 are symmetrically arranged along the center of the lens of the remote sensing and mapping instrument 5 and perpendicular to the vertical plane of the lens of the remote sensing and mapping instrument 5. The axis of rotation of the baffles 19 is parallel to the axis of rotation of the lens of the remote sensing and mapping instrument 5; Figure 1 Viewed from the perspective of the lens axis of the remote sensing and mapping instrument 5, when the lens of the remote sensing and mapping instrument 5 is symmetrical with respect to the seam of the two baffles 19, the two baffles 19 can just block the lens of the remote sensing and mapping instrument 5. Viewed from the perspective of the lens axis of the remote sensing and mapping instrument 5, the two baffles 19 can completely cover the lens of the remote sensing and mapping instrument 5.

[0038] Card slot 20 is provided on the side wall of mounting plate 4; The card plate 22 is movably mounted in the card slot 20, and the card plate 22 can move vertically relative to the card slot 20; Both clamping rods 23 are fixed to the upper end of the clamping plate 22, and the axis of the clamping rods 23 is set vertically; Two connecting slots 25 are provided one-to-one with the locking rods 23 and are opened on the upper surface of the locking slots 20. The locking rods 23 can be inserted into the connecting slots 25 accordingly. The upper end of the connecting slots 25 extends to the upper surface of the mounting plate 4, and the upper end of the locking rods 23 can pass through the connecting slots 25. The limiting spring 21 is located in the slot 20 and is used to push the card plate 22 upward; one end is fixedly connected to the lower end of the card plate 22 and the other end is fixedly connected to the bottom wall of the slot 20; the limiting spring 21 is always in a compressed state. Two locking holes 24 are provided one-to-one with the connecting grooves 25, and are respectively opened on the two corresponding baffles 19; the part of the locking rod 23 that extends out of the connecting groove 25 can be inserted into the locking hole 24.

[0039] When the two baffles 19 are completely assembled into a whole (i.e., when the lens of the aforementioned remote sensing and mapping instrument 5 is symmetrical with respect to the splice seam of the two baffles 19), under the elastic force of the limiting spring 21, the limiting spring 21 pushes the locking plate 22 and the locking rod 23 to slide as a whole, so that the upper ends of the two locking rods 23 pass through the connecting groove 25, and the upper ends of the two locking rods 23 are respectively inserted into the two locking holes 24, thereby restricting the rotation of the baffles 19. The baffles 19 can keep blocking the lens of the remote sensing and mapping instrument 5, and play a protective role for the lens. The lens surface and the baffles 19 maintain only a very small distance.

[0040] Installation and disassembly process: S1: The user rotates the turntable 16 clockwise with one hand to move the limit rod 11 away from the axis of the anti-foolproof plug 6, ensuring that the limit rod 11 is moved to a position that will not affect the insertion of the anti-foolproof plug 6 into the anti-foolproof hole. For easy observation, the driven plate 15 and the turntable 16 can be made transparent to facilitate observation of the position of the limit rod 11 in the through hole 8. S2: With the other hand, insert the foolproof plug 6 on the remote sensing and mapping instrument 5 into the foolproof plug hole on the mounting plate 4; when the hand feels the bottom end of the foolproof plug 6 against the upper surface of the driven plate 15, it indicates that it has been inserted into the correct position. S3: Release the turntable 16. Under the action of the return spring 12, the limit rod 11 is inserted into the limit hole of the anti-foolproof plug 6; installation is complete. The disassembly process is the complete opposite of the installation process described above, and will not be repeated here.

[0041] In this solution, the user can complete the assembly and disassembly with just two hands, saving labor compared to existing patents that require two people. Furthermore, this solution connects the foolproof insertion rod 6 (including the remote sensing and mapping instrument 5) via four limiting rods 11 inserted into limiting holes, while existing patents use two assembly and disassembly components. Therefore, this solution does not compromise the connection's strength. In summary, this solution allows a single user to assemble and disassemble the remote sensing and mapping instrument 5 without compromising connection strength.

[0042] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
