Abstract

This utility model discloses a foldable and portable UAV aerial survey phased-point ground marker, belonging to the field of UAV surveying technology. It includes a ground marker body with several movable hinges, two positioning slots, and two positioning plates fixedly installed at the bottom. Each positioning plate has two locking slots. This foldable and portable UAV aerial survey phased-point ground marker utilizes a mechanism where the locking blocks compress a telescopic rod and a spring, causing the spring to generate a restoring force. When the positioning plates are fully inserted into the positioning slots, the spring force causes the locking blocks to engage in the locking slots. Subsequently, an insert plate is inserted into a sliding groove, and a locking bolt is installed in the screw hole using a knob for subsequent transfer. This design prevents accidental disassembly due to vibration or collision during transport, improving the stability of the device during transport.

Description

Technical Field

[0001] This utility model belongs to the field of UAV surveying and mapping technology, specifically a UAV aerial survey phase control point ground marker that is easy to fold and carry. Background Technology

[0002] With the rapid development of surveying and mapping methods, UAV aerial surveying has gradually replaced traditional surveying and mapping methods in fields such as large-scale topographic mapping. UAV aerial surveying has the characteristics of being mobile and flexible, efficient and fast, precise and accurate, low operating cost, wide applicability, and short production cycle. As one of the most important field production activities in UAV aerial surveying, the standardization of control point production is particularly important.

[0003] Currently, existing aerial survey phased array ground markers, although they have achieved basic folding functionality, are prone to accidentally scattering due to vibration or collision during transport after folding. Staff need to repeatedly check and manually reinforce the connecting parts, which requires extra effort to maintain the folded state. Some designs rely on simple buckles or straps for fixation, which are not stable enough and pose a risk of separation during transportation, which is time-consuming and labor-intensive. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a UAV aerial survey phased control point ground marker that is easy to fold and carry. It solves the problem that although the existing aerial survey phased control point ground markers achieve basic folding function, the standard body is prone to accidentally falling apart due to vibration or collision during transportation after folding. Staff need to repeatedly check and manually reinforce the connection parts, which requires extra effort to maintain the folded state. The design that relies on simple buckles or straps for fixation is not stable enough and there is a risk of separation during transportation, which is time-consuming and laborious.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable and portable UAV aerial survey phased array ground marker, comprising a ground marker body, several movable hinges mounted on the ground marker body, two positioning slots formed on the ground marker body, two positioning plates fixedly mounted on the bottom of the ground marker body, two slots formed on the positioning plates, the positions of the positioning plates corresponding to the positioning slots, two telescopic rods mounted in the positioning slots, the ends of the telescopic rods mounted with locking blocks, the locking blocks slidably mounted in the positioning slots, corresponding sliding grooves formed on the ground marker body and the positioning plates, insert plates slidably mounted in the sliding grooves, corresponding screw holes formed on the insert plates and the ground marker body, the screw holes being threaded with locking bolts.

[0006] As a further embodiment of this utility model: a knob is installed at the end of the locking bolt, and a pinch plate is fixedly connected to the insert plate.

[0007] As a further embodiment of this utility model: the position of the locking block corresponds to the locking slot, and a spring is sleeved on the telescopic rod.

[0008] As a further embodiment of this utility model: the ground marker body is provided with a plurality of handle holes, and the handle holes are provided with threads.

[0009] As a further embodiment of this utility model: a rotating shaft is rotatably mounted on the ground marker body, and a connecting plate is rotatably mounted on the rotating shaft.

[0010] As a further embodiment of this utility model: two slots corresponding to different positions are provided on the connecting plate and the ground marker body, and a limit pin is slidably installed in the slot.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This foldable and portable UAV aerial survey phased array ground marker, equipped with a locking block, spring, telescopic rod, and insert plate, allows for easy transport during operation. When the ground marker needs to be moved, the marker is first folded, and then the handle is threaded into the handle hole. During this process, the positioning plate enters the positioning groove and presses against the locking block, causing it to move within the groove. This movement compresses the telescopic rod and spring, generating a restoring force. Once the positioning plate is fully inside the groove, the spring's force engages the locking block. The insert plate is then inserted into the sliding groove, and the locking bolt is tightened in the screw hole using a knob for subsequent transport. This design prevents the marker from accidentally disintegrating during transport due to vibration or collision, improving the device's stability during transport.

[0012] 2. This foldable and portable UAV aerial survey phased array ground marker, through the setting of a pivot, connecting plate, and limiting pin, allows for easy deployment. When using the ground marker body, first unfold the ground marker body and place it on the ground. Then rotate the connecting plate around the pivot until the slot on the connecting plate aligns with the slot on the ground marker body. Then, insert the limiting pin into the slot. The limiting pin prevents the ground marker body from folding due to accident, improving the stability of the device during operation. Attached Figure Description

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-5 As shown, this utility model provides a technical solution: a foldable and portable UAV aerial survey phased-point ground marker, including a ground marker body 1, a rotating shaft 10 rotatably mounted on the ground marker body 1, a connecting plate 4 rotatably mounted on the rotating shaft 10, and two slots 12 corresponding to each other on the connecting plate 4 and the ground marker body 1. A limiting pin 5 is slidably installed in the slot 12. Because of the limiting pin 5, after the ground marker body 1 is placed on the ground, the connecting plate 4 is rotated until the slot 12 on the connecting plate 4 corresponds to the slot 12 on the ground marker body 1. Then the limiting pin 5 can be inserted into the slot 12. The limiting pin 5 can prevent the ground marker body 1 from folding up due to accident, thus improving the stability of the device during operation.

[0021] The ground marker body 1 has several handle holes 2, and the handle holes 2 have threads 14. Because of the threads 14, when the ground marker body 1 needs to be moved, the ground marker body 1 is first folded, and then the handle can be quickly installed in the handle hole 2 through the threads 14, which improves the efficiency of the transfer work.

[0022] Several movable hinges 9 are installed on the ground sign body 1. Two positioning grooves 7 are opened on the ground sign body 1. Two positioning plates 3 are fixedly installed at the bottom of the ground sign body 1. Two slots 20 are opened on the positioning plates 3. The position of the positioning plates 3 corresponds to the positioning grooves 7. Two telescopic rods 15 are installed in the positioning grooves 7. The ends of the telescopic rods 15 are equipped with locking blocks 17. The position of the locking blocks 17 corresponds to the slots 20. A spring 16 is sleeved on the telescopic rods 15. Because of the spring 16, when the locking blocks 17 move in the positioning grooves 7, the locking blocks 17 will compress the telescopic rods 15 and the springs 16, so that the springs 16 will generate a restoring elastic force. When the positioning plates 3 are fully inserted into the positioning grooves 7, the elastic force generated by the springs 16 will drive the locking blocks 17 to engage in the slots 20, which facilitates the subsequent transportation work.

[0023] The locking block 17 is slidably installed in the positioning groove 7. The ground marker body 1 and the positioning plate 3 are provided with corresponding sliding grooves 13. The insert plate 18 is slidably installed in the sliding groove 13. The insert plate 18 and the ground marker body 1 are provided with corresponding screw holes 11. The screw holes 11 are threaded with locking bolts 19. The end of the locking bolts 19 is equipped with a knob 6. The insert plate 18 is fixedly connected with a pinch plate 8. Because of the knob 6, after the positioning plate 3 is fully inserted into the positioning groove 7, the insert plate 18 is inserted into the sliding groove 13. Then, the locking bolts 19 are installed in the screw holes 11 by the knob 6, and the subsequent transfer can be carried out. This can prevent the device from accidentally breaking apart due to vibration or collision during the transfer process, and improve the stability of the device during the transfer.

[0024] The working principle of this utility model is as follows: When the ground marker body 1 needs to be moved during operation, the ground marker body 1 is first folded, and then the handle is installed in the handle hole 2 through the thread 14. During this process, the positioning plate 3 enters the positioning groove 7, and at the same time, the positioning plate 3 presses against the locking block 17, causing the locking block 17 to move within the positioning groove 7. The movement of the locking block 17 compresses the telescopic rod 15 and the spring 16, causing the spring 16 to generate a restoring elastic force. When the positioning plate 3 is fully inserted into the positioning groove 7, the spring 16... The elastic force generated by 6 will cause the locking block 17 to engage in the slot 20. Then, the insert plate 18 is inserted into the slide 13. Then, the locking bolt 19 is installed in the screw hole 11 by the knob 6 to carry out the subsequent transfer. When using the ground sign body 1, first unfold the ground sign body 1 and place it on the ground. Then rotate the connecting plate 4. The connecting plate 4 rotates around the rotating shaft 10 until the slot 12 opened on the connecting plate 4 corresponds to the slot 12 opened on the ground sign body 1. Then, the limiting pin 5 can be inserted into the slot 12.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
