Description

Technical Field

[0001] This utility model relates to the field of urban renewal technology, and in particular to a drone device for high-density urban data collection. Background Technology

[0002] Obtaining urban data before urban redevelopment is crucial and necessary. This data provides a comprehensive and scientific basis for redevelopment planning, design, implementation, and evaluation, ensuring that redevelopment projects better meet residents' needs, enhance urban functions, optimize the environment, and achieve sustainable development.

[0003] Therefore, a data acquisition device for UAV mapping, with announcement number CN222742924U, involves pushing a slider backward into a groove during installation. When fully inserted, the locking plate aligns with the groove. Rotating the threaded rod via the handwheel moves the left movable plate inward, causing the left toothed plate to move to the right. The left toothed plate then rotates the gear clockwise, causing the right toothed plate and movable plate to move to the left. This drives the two movable plates and locking plate to approach and engage in the corresponding grooves, thus securing the slider and the mapping device body. After complete engagement, the screw aligns perfectly with the threaded groove. Finally, tightening the screw locks the handwheel into the threaded groove.

[0004] However, the handwheel is locked in position by connecting the screw to the threaded groove. But because the screw and the threaded groove are connected by threads, the screw may still loosen during use due to vibrations during the drone's flight, thus losing its fixation on the handwheel. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a drone device for high-density urban data collection.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a drone device for high-density urban data collection, comprising a drone body, a connecting seat on the lower surface of the drone body, a socket for installing a surveying device body inserted into the bottom surface of the connecting seat, a pressure plate for pressing the upper surface of the socket rotatably connected to the connecting seat near the bottom edge of the inner wall, a slot is provided on both sides of the upper surface of the pressure plate at the swing edge, and a connecting shell is fixedly installed through the connecting seat near the bottom edge of the outer wall facing each other, the openings of the two connecting shells are opposite each other and respectively near the two slots on the pressure plate in a horizontal state, a wedge is inserted into the opening of each of the two connecting shells, a horizontally arranged spring rod is provided between the opposite sides of the two wedges and the inner wall of the connecting shell, the upper surfaces of the two wedges are inclined and the bottom surface is flat, the inclined sides of the wedges are used to slide with the side of the pressure plate and the bottom surface of the wedges is used to fit with the bottom of the slot.

[0007] Preferably, the pressure plate has a horizontal groove on one side of the slot, which is parallel to the swing edge of the pressure plate. A double gear shaft is rotatably connected to the bottom of the horizontal groove, and racks are inserted into the two inner groove walls that are parallel to the swing edge of the pressure plate. The two racks have one end that passes through the inner wall of the horizontal groove and extends into the two slots respectively.

[0008] Preferably, a push plate is fixedly installed on one side of the rack extending into the slot. The push plate is slidably connected to the bottom of the slot and is used to push the wedge block to move. The tooth surfaces of the two racks mesh with the tooth surfaces above the double gear shaft.

[0009] Preferably, the upper and lower tooth surfaces of the dual gear shaft have spur teeth and chain teeth, respectively. The pressure plate is located on one side of the slot and has a longitudinal groove that is perpendicular to the swing edge of the pressure plate and communicates with the transverse groove. A sprocket is rotatably connected to the bottom of the longitudinal groove away from the transverse groove. The sprocket is connected to the chain tooth portion of the dual gear shaft by a chain.

[0010] Preferably, the sprocket is connected to the bottom of the longitudinal groove by a spring, and the chain on the sprocket and the rack in the transverse groove are staggered vertically.

[0011] Preferably, a glass cover for covering the body of the surveying device is installed on the lower surface of the socket, and an arc-shaped scraper is slidably installed on the outer wall of the glass cover.

[0013] Preferably, the two rack teeth are L-shaped when they are inserted into the inner wall of the transverse groove.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the relative position in the left-right and front-back directions can be fixed by plugging the socket and the connector. The relative position in the up-down direction can be achieved by swinging the pressure plate down to a horizontal state and pressing the upper surface of the socket in conjunction with the connector restricting the bottom surface of the socket. The wedge is pushed out of the connector shell by the elastic push of the spring rod and the bottom plane of the wedge is attached to the upper surface of the pressure plate. The position of the pressure plate can be fixed by the wedge, and the position of the socket can be fixed by fixing the position of the pressure plate. The elastic push of the spring rod ensures that the wedge is always above the pressure plate when the drone body vibrates, thus achieving the pressing and limiting of the swinging edge of the pressure plate.

[0015] 2. In this utility model, the sprocket is rotated by shaking the handwheel, and the double gear shaft is rotated under the connection of the chain. This allows the two racks to move towards each other, so that the push plate pushes the wedge block to overcome the thrust of the spring rod and is stored in the connecting shell. This achieves the misalignment of the wedge block and the slot, which makes it easy for the pressure plate to get away from the upper surface of the socket and for the socket to be removed.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] like Figures 1-4 As shown, a drone device for high-density urban data collection includes a drone body 1. A connecting seat 2 is provided on the lower surface of the drone body 1. A socket 3 for installing a surveying device body is inserted into the bottom surface of the connecting seat 2. The surveying device body can be a common camera on the market, which collects images of the urban area and analyzes them to obtain data. A pressure plate 5 for pressing the upper surface of the socket 3 is rotatably connected to the connecting seat 2 near the bottom edge of the inner wall. Under normal circumstances, the relative position in the left, right and front-back directions can be fixed by inserting the socket 3 into the connecting seat 2. The relative position in the up and down directions can be achieved by swinging the pressure plate 5 down to a horizontal state and pressing the upper surface of the socket 3 in conjunction with the restriction of the bottom surface of the socket 3 by the connecting seat 2. To fix the position of the pressure plate 5, slots 11 are provided on both sides of the upper surface of the pressure plate 5 at the swing edge. Connecting shells 4 are fixedly installed through the outer walls of the connecting seats 2 near the bottom edge. The openings of the two connecting shells 4 are opposite each other and are respectively set near the two slots 11 on the pressure plate 5 in the horizontal state. Wedges 12 are inserted into the openings of the two connecting shells 4. A horizontally set spring rod 14 is set between the opposite sides of the two wedges 12 and the inner wall of the connecting shell 4. The upper surfaces of the two wedges 12 are set with opposite sides and beveled, and the bottom surface is flat. The beveled sides of the wedges 12 are used to slide with the side of the pressure plate 5, and the bottom surface of the wedges 12 is used to fit with the bottom of the slot 11. The pressure plate 5 swings down. When the pressure plate 5 contacts the inclined edge of the upper surface of the wedge 12, the wedge 12 is forced to overcome the thrust of the spring rod 14 and be retracted into the connecting shell 4 until the pressure plate 5 is completely horizontal and fits against the upper surface of the socket 3. At this time, the pressure plate 5 and the wedge 12 are misaligned, and the elastic push of the spring rod 14 causes the wedge 12 to extend out of the connecting shell 4 and the flat surface of the bottom of the wedge 12 to fit against the upper surface of the pressure plate 5. The wedge 12 can be used to fix the position of the pressure plate 5, and the position of the socket 3 can be fixed by fixing the position of the pressure plate 5. The elastic push of the spring rod 14 ensures that the wedge 12 is always above the pressure plate 5 when the drone body 1 vibrates, thus achieving the pressing and limiting of the swing edge of the pressure plate 5.

[0021] The pressure plate 5 has a horizontal groove 6 on one side of the slot 11, which is parallel to the swinging edge of the pressure plate 5. A double gear shaft 8 is rotatably connected to the bottom of the horizontal groove 6. Two racks 10 are inserted into the two inner groove walls of the horizontal groove 6, which are parallel to the swinging edge of the pressure plate 5. The backs of the two racks 10 are L-shaped when inserted into the inner wall of the horizontal groove 6. The two racks 10 have one end facing each other, which passes through the inner wall of the horizontal groove 6 and extends into the two slots 11 respectively. A push plate 13 is fixedly installed on one side of the rack 10 extending into the slot 11. The push plate 13 slides against the bottom of the slot 11. The two racks 10 are connected and used to push the wedge 12 to move. The tooth surfaces of the two racks 10 mesh with the tooth surfaces above the double gear shaft 8. In actual use, by driving the double gear shaft 8 to rotate, the two racks 10 can move towards each other. The movement of the two racks 10 towards each other forces the two push plates 13 to move towards each other, pushing the wedge 12 in the corresponding slot 11 to overcome the thrust of the spring rod 14 and be stored in the connecting shell 4. This achieves the misalignment of the wedge 12 and the slot 11, which makes it easy for the pressure plate 5 to get away from the upper surface of the socket 3 and for the socket 3 to be removed.

[0022] The upper and lower tooth surfaces of the double gear shaft 8 have spur teeth and chain teeth, respectively. Specifically, the upper part of the double gear shaft 8 has spur teeth that mesh with two racks 10, while the lower part is a disc-shaped sprocket 7. The pressure plate 5, located on one side of the slot 11, also has a longitudinal groove 19 perpendicular to the swing edge of the pressure plate 5 and communicating with the transverse groove 6. The sprocket 7 is rotatably connected to the bottom of the longitudinal groove 19, away from the transverse groove 6. The chain teeth of the sprocket 7 are connected to the chain teeth of the double gear shaft 8 via a chain 9. The sprocket 7 is connected to the bottom of the longitudinal groove 19 via a spring, and the chain 9 on the sprocket 7 is staggered vertically with the racks 10 in the transverse groove 6. Figure 3 As shown, a handwheel is installed on the end face of the sprocket 7. Therefore, by turning the handwheel, the sprocket 7 rotates, and under the connecting action of the chain 9, the double gear shaft 8 rotates. This causes the two racks 10 to move towards each other, enabling the push plate 13 to push the wedge block 12. When the sprocket 7 rotates, the corresponding spring is wound. Therefore, after releasing the handwheel, the spring unwinds the force, causing the sprocket 7 to reverse, which in turn causes the double gear shaft 8 to reverse, resetting the racks 10 and driving the push plate 13 to return to its original position. Figure 2 The state shown.

[0023] A glass cover 15 for covering the main body of the surveying device is installed on the lower surface of the socket 3. An arc-shaped scraper 16 is slidably installed on the outer wall of the glass cover 15. A toothed ring 18 coaxial with and rotatably connected to the top edge of the outer wall of the glass cover 15 is fixedly installed at the top of the handle of the arc-shaped scraper 16. A spur gear 17 meshes with the toothed ring 18 on the bottom surface of the socket 3. In actual use, the spur gear 17 is driven to rotate by installing a motor on the socket 3, so that the meshing toothed ring 18 can rotate around the central axis of the glass cover 15. During the rotation of the toothed ring 18, the arc-shaped scraper 16 is driven to revolve around the central axis of the glass cover 15 to clean the outer wall of the glass cover 15.

[0024] The method of using this utility model is as follows: During installation, insert the socket 3 into the connector 2. The socket 3 and the connector 2 can be plugged in to fix the relative position in the left, right and front and back directions. Then, the pressure plate 5 is swung down. The contact between the side of the pressure plate 5 and the inclined edge of the upper surface of the wedge 12 forces the wedge 12 to overcome the pushing force of the spring rod 14 and be stored in the connecting shell 4 until the pressure plate 5 is completely horizontal and fits against the upper surface of the socket 3. At this time, the pressure plate 5 and the wedge 12 are misaligned. The elasticity of the spring rod 14 pushes the wedge 12 out of the connecting shell 4 and the flat surface of the bottom of the wedge 12 fits against the upper surface of the pressure plate 5. The position of the pressure plate 5 can be fixed by the wedge 12.

[0025] The wiring diagrams of the UAV body 1 and the motor in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the UAV body 1 and the motor will be explained in more detail.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
