Description

Technical Field

[0001] This invention relates to the field of camera technology, and more specifically to a camera for data acquisition. Background Technology

[0002] There are many types of cameras, but their basic principle is the same: converting optical image signals into electrical signals for storage or transmission. When we photograph an object, the light reflected from that object is collected by the camera lens and focused onto the light-receiving surface of the imaging device (such as the target surface of a camera tube). The imaging device then converts the light into electrical energy, resulting in a "video signal." Since photoelectric signals are very weak, they need to be amplified by a preamplifier circuit, processed and adjusted by various circuits, and finally, the standard signal can be sent to a recording medium such as a video recorder for recording, or transmitted through a transmission system or displayed on a monitor.

[0003] Among them, data acquisition cameras are devices used to collect image and video data, and are widely used in many fields, such as industrial monitoring, scientific research, medical imaging and the Internet of Things.

[0004] Chinese patent document CN219268977U discloses a spherical camera, including a housing and a mounting plate, and further including: a mounting ring seat disposed at the lower end of the housing and integrally formed with the housing; a mounting base plate disposed inside the mounting ring seat and fixedly connected to the mounting ring seat; a second mounting bracket disposed below the mounting base plate and fixedly connected to the mounting base plate; a camera disposed below the second mounting bracket; a microprocessor device disposed above the mounting base plate and fixedly connected to the mounting base plate; and the camera being electrically connected to the microprocessor device.

[0005] A first mounting bracket is disposed on one side of the fixed plate and welded to the fixed plate. A first motor is disposed above the first mounting bracket and fixedly connected to the first mounting bracket. A connecting hole is provided at the upper end of the housing and rotatably connected to the first mounting bracket. A second connecting rod is disposed below the first motor, and one end of the second connecting rod is integrally connected to the output end of the first motor. The other end of the second connecting rod extends into the interior of the connecting hole and is engaged with the housing.

[0006] The second motor is located on one side of the second mounting bracket and is fixedly connected to the second mounting bracket. The camera has a first connecting rod on both sides and is fixedly connected to the camera. The first connecting rod is rotatably connected to the second mounting bracket. A bevel gear transmission mechanism is located below the second motor and is integrated with the output end of the second motor and one end of the first connecting rod.

[0007] When in operation, the camera captures images of the environment in front of it to achieve monitoring. The second motor is activated to drive the bevel gear transmission mechanism, which in turn drives the first connecting rod to rotate. As the first connecting rod rotates, the camera rotates, changing its orientation to achieve panoramic shooting. The first motor is activated to drive the second connecting rod to rotate, which in turn drives the main body of the spherical camera to rotate, changing the camera's angle.

[0008] The PTZ camera is rotatably connected to the second end of the main body. The PTZ camera contains a second lens. During operation, the camera's control system controls the first drive motor, which in turn drives the inner cover to rotate along the second axis. The inner cover, in turn, drives the PTZ camera to rotate along the second axis. When the first lens detects a location requiring special attention, the control system for image acquisition controls the PTZ camera to quickly rotate along the second axis to the corresponding position. The second lens in the PTZ camera then tracks and captures the image at that location. The PTZ camera can be connected to the second end of the inner cover via a main bracket, allowing it to rotate along a third axis on the main bracket.

[0009] In the above technology, the PTZ camera is connected to the second end of the inner cover through the main bracket. The main bracket and the main body are rotated together. During use, dust or rainwater can easily enter the main body through the gap between the main bracket and the main body, thereby affecting the shooting effect of the camera. Summary of the Invention

[0010] This invention provides a camera for data acquisition, aiming to solve the technical problem in the prior art where the PTZ camera is connected to the second end of the inner cover via a main bracket, and the main bracket and the main body are rotated together. During use, dust or rainwater can easily enter the main body through the gap between the main bracket and the main body, thus affecting the shooting effect of the camera.

[0011] A camera for data acquisition according to the present invention includes a mounting frame, a fixed housing disposed on the mounting frame, a rotating frame rotatably fitted on the fixed housing, and a camera head mounted on the rotating frame. A sealing device is provided between the fixed housing and the rotating frame. The sealing device includes a sealing component disposed inside the fixed housing and a sealing block slidably fitted on the rotating frame. The sealing component includes multiple sealing plates, which are evenly disposed on the inner wall of the fixed housing. One end of each sealing plate is connected to the inner wall of the fixed housing. The sealing block slides into the fixed housing, pressing against the multiple sealing plates. The ends of the multiple sealing plates facing away from the inner wall of the fixed housing are folded upwards. The multiple sealing plates are pressed and located between the inner wall of the fixed housing and the outer peripheral surface of the sealing block, for sealing the gap between the fixed housing and the rotating frame.

[0012] Beneficial effects: By setting up a sealing device, when the sealing block slides into the fixed housing, it can squeeze multiple sealing sheets. The ends of the multiple sealing sheets away from the inner wall of the fixed housing are folded upwards. The multiple sealing sheets are squeezed and located between the inner wall of the fixed housing and the outer peripheral surface of the sealing block, thereby achieving the sealing of the gap between the fixed housing and the rotating frame, which can improve the shooting effect of the camera.

[0013] Preferably, the rotating frame is provided with a sliding groove, and the sealing block is provided with a slider that is adapted to the sliding groove, and the slider slides in the sliding groove.

[0014] Preferably, the rotating frame is provided with a driving device, which includes a driving component installed in the rotating frame and a screw installed on the output shaft of the driving component. The screw is threadedly engaged with the sealing block.

[0015] Beneficial effects: By setting up the drive device, starting the drive component can drive the screw to rotate, which in turn drives the sealing block to slide, thereby realizing convenient adjustment of the sealing block.

[0016] Preferably, the sealing sheet includes a fixing part installed on the fixed shell and a folding part disposed on the fixing part. In the initial state, a plurality of the folding parts are horizontally arranged and abut together to seal the fixed shell.

[0017] Beneficial effects: The fixed part enables the installation of the folding part, making the installation of the folding part within the fixed housing more stable. When multiple folding parts fold upwards at the ends facing away from the inner wall of the fixed housing, they are compressed and positioned between the inner wall of the fixed housing and the outer circumference of the sealing block, thus sealing the gap between the fixed housing and the rotating frame. When the multiple folding parts return to their original position and rotate to a horizontal state, they seal the fixed housing. Simultaneously, with the sealing block away from the fixed housing, the rotation of the rotating frame and the camera head prevents the sealing block from rotating, thus avoiding friction between the sealing block and the multiple sealing plates, which could easily damage the sealing plates.

[0018] Preferably, the sealing block is configured as a frustum-shaped block, with the top end of the sealing block being the small end and the bottom end being the large end, and a clamping sleeve for squeezing the sealing sheet is provided inside the fixing shell.

[0019] Beneficial effects: By setting up the compression sleeve, multiple sealing plates can be squeezed, thereby enabling the multiple sealing plates to better fit onto the sealing block, achieving a good seal between the fixed shell and the rotating frame.

[0020] Preferably, the fixed shell is provided with a sliding groove, and the clamping sleeve is provided with a sliding block adapted to the sliding groove, the sliding block being slidably engaged with the sliding groove.

[0021] Preferably, the clamping sleeve is provided with a linkage device, which includes a lifting frame for driving the clamping sleeve to slide and a linkage component for driving the lifting frame to move.

[0022] Beneficial effects: By setting up a linkage device, when the linkage component moves, it can drive the lifting frame to move, and then drive the pressing sleeve to move through the lifting frame, so as to realize convenient adjustment of the pressing sleeve.

[0023] Preferably, the linkage assembly includes a linkage rod connected to the first screw and a second screw disposed on the linkage rod. The second screw is threadedly engaged with the lifting frame, and the threads of the second screw and the first screw have opposite directions.

[0024] Preferably, the clamping sleeve has an installation groove, and a pushing device is provided in the installation groove for pushing the sealing sheet to flip down and reset.

[0025] Preferably, the pushing device includes a pushing plate that is installed and fitted into the mounting groove for pushing the sealing sheet and a torsion spring for driving the pushing plate to rotate to a horizontal state. One end of the torsion spring is connected to the clamping sleeve and the other end is connected to the pushing plate. When the pushing plate rotates from a vertical state to a horizontal state, the pushing plate pushes the sealing sheet.

[0026] Beneficial effects: With the setting of the pushing device, when the sealing block is inserted into the fixed shell, the pushing plate is squeezed and the torsion spring is compressed. When the sealing block descends, the torsion spring can drive the pushing plate to rotate from the vertical state to the horizontal state. The pushing plate pushes the sealing sheet, so that the sealing sheet can be quickly reset.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. In this invention, by setting up a sealing device, when the sealing block slides into the fixed shell, it can squeeze multiple sealing sheets. The ends of the multiple sealing sheets away from the inner wall of the fixed shell are folded upwards. The multiple sealing sheets are squeezed and located between the inner wall of the fixed shell and the outer peripheral surface of the sealing block, thereby achieving the sealing of the gap between the fixed shell and the rotating frame, which can improve the shooting effect of the camera.

[0029] 2. In this invention, the installation of the folding parts is achieved by setting the fixing part, making the installation of the folding parts in the fixing shell more stable. By setting the folding parts, when the ends of multiple folding parts away from the inner wall of the fixing shell are folded upward, multiple folding parts are squeezed and located between the inner wall of the fixing shell and the outer peripheral surface of the sealing block, the gap between the fixing shell and the rotating frame can be sealed. When multiple folding parts are reset and rotated to a horizontal state, multiple folding parts can seal the fixing shell. At the same time, after the sealing block is away from the fixing shell, it can avoid the phenomenon that the sealing block will rotate during the rotation of the rotating frame driving the shooting head, and the sealing block will rub against multiple sealing pieces, causing the sealing pieces to be easily damaged.

[0030] 3. In this invention, by setting the compression sleeve, multiple sealing sheets can be squeezed, thereby enabling the multiple sealing sheets to better fit onto the sealing block, achieving a good seal between the fixed shell and the rotating frame.

[0031] 4. In this invention, by setting up a pushing device, when the sealing block is inserted into the fixed shell, the pushing plate is squeezed and the torsion spring is compressed. When the sealing block descends, the torsion spring can drive the pushing plate to rotate from a vertical state to a horizontal state. The pushing plate pushes the sealing sheet, so that the sealing sheet can be quickly reset. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0043] Reference Figures 1-8 The present invention discloses a camera for data acquisition, comprising a mounting frame 1, a fixed housing 2 disposed on the mounting frame 1, a rotating frame 3 rotatably fitted on the fixed housing 2, and a camera head 4 mounted on the rotating frame 3. The mounting frame 1 is used to mount the camera, and the camera head 4 is rotatably fitted on the rotating frame 3. When the camera needs to be used, it is first mounted on the mounting frame 1, and then the camera head 4 is used to capture data. Furthermore, by rotating the camera head 4, the rotation angle of the camera head 4 can be adjusted, thereby enabling shooting operations at different positions.

[0044] Among them, reference Figures 2-5 A sealing device 5 is provided between the fixed shell 2 and the rotating frame 3. The sealing device 5 is used to seal the gap between the fixed shell 2 and the rotating frame 3. The sealing device 5 includes a sealing component 51 disposed in the fixed shell 2 and a sealing block 52 slidably fitted on the rotating frame 3. The sealing component 51 includes a plurality of sealing pieces 511. The plurality of sealing pieces 511 are evenly disposed on the inner wall of the fixed shell 2. The sealing pieces 511 are made of elastic rubber material. One end of the sealing piece 511 is connected to the inner wall of the fixed shell 2. The sealing piece 511 includes a fixing part 512 fixedly installed on the fixed shell 2 and a folding part 513 fixedly disposed on the fixing part 512. The plurality of fixing parts 512 are fixedly connected and have a ring structure. The folding part 513 has a fan-shaped structure. In the initial state, the plurality of folding parts 513 are horizontally disposed and abut together to seal the fixed shell 2.

[0045] Reference Figures 2-6The sealing block 52 is configured as a frustum-shaped block, with the top end of the sealing block 52 being the small end and the bottom end being the large end. A sliding groove 31 is provided on the rotating frame 3, and the sliding groove 31 is vertically arranged. A slider 521 adapted to the sliding groove 31 is fixedly provided on the sealing block 52, and the slider 521 slides in the sliding groove 31. The sealing block 52 slides into the fixed shell 2, pressing the folded portions 513 of the multiple sealing pieces 511. The ends of the multiple folded portions 513 that are away from the inner wall of the fixed shell 2 are folded upwards. The multiple folded portions 513 are pressed and located between the inner wall of the fixed shell 2 and the outer peripheral surface of the sealing block 52, which is used to seal the gap between the fixed shell 2 and the rotating frame 3.

[0046] Reference Figure 5 and Figure 6 A drive device 6 is installed inside the rotating frame 3. The drive device 6 includes a drive component 61 fixedly installed inside the rotating frame 3 and a screw 62 fixedly installed on the output shaft of the drive component 61. The drive component 61 is directly powered by an electric motor. The housing of the drive component 61 is fixedly connected to the rotating frame 3. The screw 62 is vertically arranged. A plate (not shown in the figure) for supporting the rotation of the screw 62 can be installed inside the rotating frame 3. The screw 62 is threadedly engaged with the sealing block 52. When the drive component 61 is started, it can drive the screw 62 to rotate. When the screw 62 rotates, it drives the sealing block 52 to rise and fall. The sealing block 52 drives the slider 521 to slide within the slide groove 31.

[0047] Reference Figure 2 , Figure 3 and Figure 6 The fixed housing 2 is provided with a pressing sleeve 7 for pressing the sealing sheet 511. The pressing sleeve 7 can be made of rubber material. The inner wall of the pressing sleeve 7 is provided with an inclined surface, and the inclined surface is inclined inward from the inside of the fixed housing 2 along the vertical upward direction. The fixed housing 2 is provided with a sliding groove 21, which is vertically arranged. A sliding block 71 adapted to the sliding groove 21 is fixedly provided on the pressing sleeve 7. The sliding block 71 is slidably engaged with the sliding groove 21.

[0048] Reference Figure 2 and Figure 5The clamping sleeve 7 is equipped with a linkage device 8, which includes a lifting frame 81 for sliding the clamping sleeve 7 and a linkage assembly 82 for moving the lifting frame 81. The lifting frame 81 has a U-shaped structure, and its bottom end is fixedly connected to the clamping sleeve 7. The linkage assembly 82 includes a linkage rod 821 fixedly connected to the first screw 62 and a second screw 822 fixedly mounted on the linkage rod 821. The second screw 822 and the linkage rod 821 are vertically arranged. The moving rod 821 is an active telescopic rod. The bottom end of the linkage rod 821 is a fixed rod, and the top end is a telescopic rod. The bottom of the screw 822 can be provided with a linkage groove (not shown in the figure). After the top end of the linkage rod 821 is inserted into the linkage groove of the screw 822, when the linkage rod 821 rotates, it can drive the screw 822 to rotate. The fixed shell 2 supports the rotation of the screw 822. The screw 822 is threadedly engaged with the lifting frame 81. The threads of the screw 822 and the screw 62 are opposite in direction.

[0049] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 When screw 62 rotates, it drives linkage rod 821 to rotate, which in turn drives screw 822 to rotate. When screw 822 rotates, it drives lifting frame 81 to rise and fall. Lifting frame 81 drives pressing sleeve 7 to rise and fall. At the same time, pressing sleeve 7 drives sliding block 71 to slide in sliding groove 21. When sealing block 52 slides into fixed shell 2 and rises, pressing sleeve 7 descends simultaneously. When the multiple folds 513 of sealing block 52 are squeezed, they can push the multiple folds 513 to fold upward. After the folds 513 are folded, pressing sleeve 7 is located between folds 513 and fixed part 512. At this time, sealing block 52 and sealing sheet 511 seal the space between fixed shell 2 and rotating frame 3 (its state is as follows). Figure 5 (As shown); When screw 62 rotates, it drives the sealing block 52 to slide downwards towards the outside of the fixed shell 2. At the same time, the clamping sleeve 7 rises. The sealing block 52 no longer presses against the multiple folds 513. The multiple folds 513 fold downwards to reset. After the sealing block 52 resets, the clamping sleeve 7 also resets, and the clamping sleeve 7 no longer contacts the sealing plate 511. At this time, the multiple folds 513 are in a horizontal state (their state is as shown). Figure 4 As shown, when the camera head 4 rotates, it drives the rotating frame 3 to rotate. When the rotating frame 3 rotates, it drives the sealing block 52 to rotate. The sealing block 52 no longer contacts the folding part 513, which can avoid the phenomenon that the folding part 513 is easily worn when the sealing block 52 rotates, resulting in low efficiency of the folding part 513.

[0050] Reference Figure 5 , Figure 7 and Figure 8The clamping sleeve 7 has an installation groove 72, which is an arc-shaped groove. A pushing device 9 is installed within the installation groove 72 to push the sealing sheet 511 downwards and reset it. The pushing device 9 includes a pushing plate 91 installed in the installation groove 72 and used to push the sealing sheet 511, and a torsion spring 92 used to rotate the pushing plate 91 to a horizontal position. The pushing plate 91 is an arc-shaped plate, with rotating rods fixedly installed at both ends. The rotating rods are rotatably engaged with the clamping sleeve 7. One end of the torsion spring 92 is fixedly connected to the clamping sleeve 7, and the other end is fixedly connected to the pushing plate 91. When the sealing block 52 is inserted into the fixed housing 2 and multiple sealing sheets 511 are compressed, the pushing plate 91 is located within the installation groove 72, and the side of the pushing plate 91 facing away from the inner wall of the fixed housing 2 abuts against the side of the folded part 513 (its state is as follows). Figure 7 As shown), at this time, the torsion spring 92 is in a compressed state. When the sealing block 52 slides to the outside of the fixed shell 2, the sealing block 52 no longer squeezes the folding part 513 and the push plate 91. The torsion spring 92 releases its elastic restoring force, which drives the push plate 91 to rotate. When the push plate 91 rotates from the vertical state to the horizontal state, the push plate 91 pushes the sealing piece 511 to reset.

[0051] The implementation principle of the camera for data acquisition according to the present invention is as follows: When the camera needs to be used, it is first installed through the mounting bracket 1. The linkage rod 821 is activated, and the top end of the linkage rod 821 is inserted into the linkage groove of the second screw 822. The linkage rod 821 is connected to the second screw 822. Then, the drive component 61 is activated, which can drive the first screw 62 to rotate. When the first screw 62 rotates, it drives the sealing block 52 to rise and fall. The sealing block 52 drives the slider 521 to slide in the sliding groove 31. At the same time, the first screw 62 drives the linkage rod 821 and the second screw 822 to rotate. When the sealing block 52 moves into the fixed shell 2... As the sliding part rises, the clamping sleeve 7 descends simultaneously. The sealing block 52 presses against multiple folding parts 513, which can push the multiple folding parts 513 to fold upward. After the folding parts 513 are folded, the clamping sleeve 7 is located between the folding parts 513 and the fixed part 512. At this time, the sealing block 52 and the sealing plate 511 seal between the fixed shell 2 and the rotating frame 3. The push plate 91 is located in the mounting groove 72. The side of the push plate 91 away from the inner wall of the fixed shell 2 abuts against the side of the folding part 513, and the torsion spring 92 is in a compressed state. Then, the camera head 4 takes pictures to collect data.

[0052] When the camera head 4 needs to be rotated and adjusted for shooting at different positions, the drive unit 61 is activated, which drives the screw 62 to rotate. When the screw 62 rotates, it drives the sealing block 52 to slide down towards the outside of the fixed shell 2. At the same time, the clamping sleeve 7 rises. The sealing block 52 no longer presses against the multiple folds 513. The multiple folds 513 fold down to reset. After the sealing block 52 resets, the clamping sleeve 7 also resets, and the clamping sleeve 7 no longer contacts the sealing plate 511. At this time, the multiple folds 513 are in a horizontal state. At the same time, when the sealing block 52 slides towards the outside of the fixed shell 2, the sealing block 52 no longer presses against the folds 513 and the push plate 91. The torsion spring 92 releases its elastic restoring force, driving the push plate 91 to rotate. When the push plate 91 rotates from a vertical state to a horizontal state, the push plate 91 pushes the sealing plate 511 to reset.

[0053] When the camera head 4 rotates, the linkage rod 821 works first. The top of the linkage rod 821 slides out of the linkage groove of the screw 822. The linkage rod 821 and the screw 822 are no longer connected. The camera head 4 drives the rotating frame 3 to rotate. When the rotating frame 3 rotates, it drives the sealing block 52 to rotate. The sealing block 52 no longer contacts the folding part 513, thus realizing the efficient shooting operation of the camera.
