Description

Technical Field

[0001] This utility model relates to the field of UAV oblique photogrammetry engineering surveying technology, specifically a UAV oblique photogrammetry engineering surveying device. Background Technology

[0002] UAV oblique photogrammetry is a new type of surveying technology that integrates UAV technology, oblique photogrammetry technology, and surveying data processing technology.

[0003] According to a public notice (Announcement No.: CN221189144U) of an UAV oblique photogrammetry engineering surveying device, the aforementioned application uses a connection and positioning mechanism to quickly connect and fix the mounting guide rail and the movable mounting block, thereby quickly connecting and fixing the movable surveying mechanism. This allows for stable installation and use of the movable surveying mechanism, which can perform tilting and other operations, facilitating surveying. However, the aforementioned fixing method relies solely on a pull rod to fix the movable surveying mechanism, resulting in poor fixing effectiveness. It is prone to loosening upon impact. To address this issue, we propose an UAV oblique photogrammetry engineering surveying device. Utility Model Content

[0004] The purpose of this invention is to provide an unmanned aerial vehicle (UAV) oblique photogrammetry engineering surveying device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drone oblique photogrammetry engineering surveying device, comprising a drone body, a frame fixedly mounted on the surface of the drone body, a guide rail fixedly mounted on the bottom of the drone body, the guide rail being slidably connected to a slide rail, the slide rail being fixedly mounted on the surface of a connecting frame, a camera being disposed at the bottom of the connecting frame, and a control component being disposed within the guide rail, the control component comprising:

[0006] A support rod, wherein a fixing block is provided at the front end of the support rod;

[0007] A movable rod, which is connected to a support rod via a torsion spring;

[0008] The fastener is used to connect the guide rail and the slide rail, thereby achieving the connection between the guide rail and the slide rail, enhancing the stability of the connection after the guide rail and the slide rail are connected, and preventing loosening due to impact.

[0009] Preferably, a fixing block is fixedly installed at the front end of the support rod, the surface of the support rod is hinged to the movable rod, the surface of the movable rod is fixedly connected to one side of the torsion spring, and the other side of the torsion spring is fixedly installed on the surface of the support rod. When the movable rod abuts against the surface of the through hole, it can be folded under the support of the torsion spring.

[0010] Preferably, the fixing component includes a cylinder with a through hole on its surface and a slot inside the cylinder. The movable rod can only be separated from the cylinder when the through hole on the surface of the cylinder is parallel to the movable rod.

[0011] Preferably, a threaded rod is fixedly installed on the surface of the cylinder. The threaded rod passes through the guide rail and is rotatably connected to the guide rail. The surface of the guide rail is rotatably connected to the circular plate. The surface of the circular plate is fixedly connected to the surface of the threaded rod. When the circular plate rotates, the threaded rod can drive the cylinder to perform circumferential motion within the guide rail.

[0012] Preferably, the inner wall of the circular plate is fixedly connected to one end of the spring, and the other end of the spring is fixedly installed on the surface of the pressure block. When the pressure block is no longer under force, it can bounce up under the support of the spring.

[0013] Preferably, the pressure block is fitted to the inner wall of the circular plate, and a limiting rod is fixedly installed on the surface of the pressure block. The limiting rod passes through the circular plate and is slidably connected to the circular plate. When the pressure block is subjected to a squeezing force, the limiting rod fixed on the surface of the pressure block can retract into the circular plate.

[0014] Preferably, a fixing ring is fixedly installed on the surface of the guide rail, and a retaining tooth is fixedly installed on the inner wall of the fixing ring. The retaining tooth in the fixing ring can limit the rotation of the limiting rod and the circular plate.

[0015] Compared with the prior art, this utility model provides an unmanned aerial vehicle (UAV) oblique photogrammetry engineering surveying device, which has the following beneficial effects:

[0016] 1. This UAV oblique photography engineering surveying device, through the setting of control components, inserts a slide rail into a guide rail. The support rod fixed on the surface of the slide rail moves into the cylinder. When the movable rod hinged to the surface of the support rod comes into contact with the through hole opened on the surface of the cylinder, the movable rod will bend under the support of the torsion spring and enter the slot in the cylinder from the through hole. When the force of contact is lost, it will bounce up under the support of the torsion spring and lock into the slot. The cylinder and the support rod are fixed by the fixing block, thereby achieving the connection between the guide rail and the slide rail, enhancing the stability of the connection between the guide rail and the slide rail, and avoiding loosening due to impact.

[0017] 2. This UAV oblique photography engineering surveying device, by setting a fixing component, allows the cylinder fixed to the surface of the threaded rod to rotate synchronously when the threaded rod rotates. Therefore, when the pressure block inside the circular plate is not subjected to compressive force, the limiting rod fixed to the surface of the pressure block will be locked into the two sets of locking teeth in the fixing ring. The locking teeth restrict the limiting rod, so the circular plate and the threaded rod cannot rotate, and the cylinder and the support rod cannot be separated. This method can enhance the stability of the guide rail and slide rail after connection and achieve the purpose of secondary restriction. Attached Figure Description

[0025] like Figures 1-6 As shown, this utility model provides a technical solution: a drone oblique photogrammetry engineering surveying device, including a drone body 1, a frame 2 fixedly mounted on the surface of the drone body 1, a guide rail 3 fixedly mounted on the bottom of the drone body 1, the guide rail 3 slidably connected to a slide rail 4, the slide rail 4 fixedly mounted on the surface of a connecting frame 5, a camera 6 disposed at the bottom of the connecting frame 5, and a control component 7 disposed inside the guide rail 3. The control component 7 includes: a support rod 71, a movable rod 72, a fixing block 73, a torsion spring 74, and a fixing member 75, the fixing member 75 being used to secure the guide rail 3 and the slide rail 4. When the movable rod 72, hinged to the surface of the support rod 71, comes into contact with the through hole 752 on the surface of the cylinder 751, the movable rod 72 will fold under the support of the torsion spring 74 and enter the slot 753 inside the cylinder 751 through the through hole 752. When the force of contact is lost, it will spring up under the support of the torsion spring 74 and lock into the slot 753. The cylinder 751 and the support rod 71 are fixed by the fixing block 73, thereby achieving the connection between the guide rail 3 and the slide rail 4, enhancing the stability of the connection between the guide rail 3 and the slide rail 4, and preventing loosening due to impact.

[0026] A fixing block 73 is fixedly installed at the front end of the support rod 71. The surface of the support rod 71 is hinged to the movable rod 72. The surface of the movable rod 72 is fixedly connected to one side of the torsion spring 74, and the other side of the torsion spring 74 is fixedly installed on the surface of the support rod 71. When the movable rod 72 abuts against the surface of the through hole 752, it can be folded under the support of the torsion spring 74. The fixing member 75 includes a cylinder 751. The surface of the cylinder 751 has a through hole 752, and the inside of the cylinder 751 has a slot 753. The movable rod 72 can only be separated from the cylinder 751 when the through hole 752 on the surface of the cylinder 751 is parallel to the movable rod 72. A threaded rod 754 is fixedly installed on the surface of the cylinder 751. The threaded rod 754 passes through the guide rail 3 and is rotatably connected to the guide rail 3. The surface of the guide rail 3 is rotatably connected to the circular plate 755. The surface of the circular plate 755 is fixedly connected to the surface of the threaded rod 754. When the circular plate 755 rotates, the threaded rod 754 can drive the cylinder 751 to perform circular motion within the guide rail 3. The inner wall of the circular plate 755 is fixedly connected to one end of the spring 756. The other end of the spring 756 is fixedly installed on the surface of the pressure block 757. When the pressure block 757 is no longer under force, it can spring up under the support of the spring 756. The pressure block 757 fits against the inner wall of the circular plate 755. A limit rod 758 is fixedly installed on the surface of the pressure block 757. The limit rod 758 passes through the circular plate 755 and is slidably connected to the circular plate 755. When the pressure block 757 is subjected to a compressive force, the limit rod 758 fixed on the surface of the pressure block 757 can retract into the circular plate 755. A retaining ring 759 is fixedly installed on the surface of the guide rail 3. A retaining tooth 750 is fixedly installed on the inner wall of the retaining ring 759. The retaining tooth 750 in the retaining ring 759 can limit the rotation of the limiting rod 758 and the circular plate 755.

[0027] In this utility model, when it is necessary to use the UAV body 1 to complete the camera engineering survey, the slide rail 4 fixed on the surface of the connecting frame 5 is inserted into the guide rail 3 at the bottom of the UAV body 1. After insertion, the support rod 71 fixed on the surface of the slide rail 4 will be inserted into the cylinder 751. When the support rod 71 fixed on the surface of the slide rail 4 moves into the cylinder 751, the movable rod 72 hinged to the surface of the support rod 71 will contact the through hole 752 opened on the surface of the cylinder 751, and the movable rod 72 will... 2. Supported by the torsion spring 74, it folds over and enters the slot 753 inside the cylinder 751 through the through hole 752. When the resistance is lost, it bounces up under the support of the torsion spring 74 and locks into the slot 753. The cylinder 751 and the support rod 71 are fixed by the fixing block 73, thereby connecting the guide rail 3 and the slide rail 4, enhancing the stability of the connection between the guide rail 3 and the slide rail 4, and preventing loosening due to impact. After connection, the drone body 1 is started to drive the connection. The frame 5 is raised. When the connecting frame 5 is raised, the camera 6 at the bottom of the connecting frame 5 can measure the flight distance. After the measurement is completed, the drone body 1 is lowered to the ground. Then, the pressure block 757 is pressed on the surface of the guide rail 3. When the pressure block 757 is subjected to the squeezing force, the limiting rod 758 fixed on the surface of the pressure block 757 will move out from the gap between the two sets of teeth 750 in the fixing ring 759. After it moves out, the pressing force is maintained, and the circular plate 75 is moved on the surface of the guide rail 3. 5. When the circular plate 755 rotates, the threaded rod 754 fixed on the surface of the circular plate 755 can drive the cylinder 751 to rotate synchronously. When the cylinder 751 rotates, the through hole 752 opened on the surface of the cylinder 751 will gradually become parallel to the movable rod 72. After becoming parallel, the support rod 71 and the movable rod 72 can be moved out from the through hole 752, thereby releasing the fixation on the guide rail 3 and the slide rail 4. Then the guide rail 3 and the slide rail 4 can be separated, and the connecting frame 5 can be separated from the UAV body 1.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
