Description

Technical Field

[0001] The invention relates to the technical field of image shooting, in particular to a camera. Background Art

[0002] Camera (CAMERA or WEBCAM), also known as computer camera, computer eye, electronic eye, etc., is a video input device that is widely used in video conferencing, telemedicine and real-time monitoring.

[0003] A camera generally has basic functions such as video recording / transmission and static image capture. After the lens captures the image, the photosensitive component circuit and control components in the camera process the image and convert it into a digital signal that can be recognized by the computer. It is then input into the computer through a parallel port or USB connection and the image is restored by the software.

[0004] Ordinary people can also use the camera to talk and communicate with each other on the Internet with images and sounds. In addition, people can also use it for various popular digital images, audio and video processing, etc.

[0021] The present invention provides a camera having the following beneficial effects:

[0022] 1. The camera is driven by the driving mechanism through the coordinated use of the driving mechanism, the automatic cleaning mechanism and the cleaning mechanism, and then the driving plate is driven to move. At the same time, the transmission gear rotates under the driving action of the toothed plate, thereby driving the worm to rotate. The worm drives the worm wheel to rotate to release the wiping cloth wrapped around the installation roller. When one side of the circular camera moves to the inner side of the long strip nozzle, one side of the moving plate contacts one end of the piston rod at this time, and the driving plate carries the camera base and the circular camera to move continuously. The piston rod will be pushed into the inner cavity of the piston cylinder to move, and the cleaning agent in the inner cavity of the piston cylinder is pushed into the long strip nozzle through the water pipe for spraying. In the spraying process, the circular camera is continuously moving, so that the cleaning agent can be evenly sprayed on the surface of the circular camera, and the driving motor is started to control the rotation of the bidirectional screw rod, thereby driving the two The pushing frames are close to each other to push the semicircular cleaning plate to move. The movement of the semicircular cleaning plate pushes the wiping cloth on both sides of the circular camera to wrap around the circular camera. The driving plate continues to move to push the passive plate to slide on the guide rod, and at the same time drives the top plate to move. The top plate drives the upper fixed plate and the lower mounting plate to move. When the upper fixed plate moves, the bevel gear and the helical racks on both sides of the bevel gear contact each other in turn, and the helical rack on the left side of the bevel gear rotates clockwise, and the helical rack on the right side of the bevel gear drives the bevel gear to rotate in the opposite direction, thereby driving the rotating column to drive the top plate to rotate repeatedly, so that the semicircular cleaning plate carries the wiping cloth to reciprocate on the circular camera to realize automatic wiping, and the wiping effect is good. The circular camera is stored in the inner cavity of the protective shell for protection while realizing self-cleaning, thereby improving the functionality of the equipment.

[0023] 2. The camera, through the use of a protective cutting mechanism, utilizes a driving motor to drive gear 1 to rotate and then drives the inner gear ring to rotate, and utilizes the inner gear ring to drive two sets of mounting rods to rotate. When the mounting rods rotate, one of the passive gears meshes with half gear ring 1, and the other passive gear meshes with half gear ring 2, which will drive the slider to rotate, and then cooperate with the reciprocating screw to push out the cleaning blade. When the cleaning blade is extended, the plastic bag or cloth can be scratched or pushed off. The two cleaning blades rotate to cut the plastic bag or cloth on the end of the external reinforcement tube, and automatic cleaning can be achieved.

[0024] 3. This camera, through the use of a transparent protection mechanism, when it is in a harsh environment or when the circular camera needs to be protected, when the conical electromagnet block contacts the circular camera on the inner side of the closed door, the conical electromagnet block generates a magnetic attraction, which is then adsorbed with the metal sheet on the inner wall of the inclined groove, and the closed door cannot be pushed to move to both sides. At this time, the electromagnet will not have a fixing effect on the transparent frame, so that the closed door and the transparent frame move with the camera base. The transparent frame and the closed door protect the circular camera without affecting the use of the circular camera. It can be used normally in some harsh environments, avoiding damage to the circular camera and improving the stability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] A driving motor 6 is installed at one end of the upper fixed plate 10, and the output shaft of the driving motor 6 is fixedly connected to one end of the bidirectional screw 7. A main motor 36 is fixedly installed outside the protective shell 1, and the output shaft of the main motor 36 is fixedly connected to the end of the driving screw 15.

[0053] In summary, when the camera is in use, under normal use, the camera base 5 and the circular camera 44 are outside the protective housing 1. When the camera base 5 and the circular camera 44 need to be stored and cleaned, the main motor 36 is started to drive the driving screw 15 to rotate. At this time, the driving screw 15 drives the driving plate 14 to move. The driving plate 14 can move horizontally under the action of the two guide rods 49. At this time, the driving plate 14 moves toward the inner cavity of the worm 4. During the movement, the conical push block 42 contacts the inclined groove 56. Since the conical push block 42 is conical and fits the inner wall of the inclined groove 56, the two closed doors are closed. 55 is pushed to both sides, thereby separating the two closed doors 55, so that the camera base 5 and the circular camera 44 can smoothly enter the inner cavity of the protective shell 1. While the driving plate 14 moves, the transmission gear 2 rotates under the driving action of the toothed plate 41, thereby driving the worm 4 to rotate. The worm 4 drives the worm wheel 59 to rotate to release the wiping cloth 17 wound on the installation roller 16. At the same time, during the rotation of the driving screw 15, with the assistance of the guide rod 49, the moving plate 51 will also move to one side synchronously. After the camera base 5 and the circular camera 44 enter the inner cavity of the protective shell 1, the driving plate 14 is still moving. At this time, the wiping cloth 17 is The wiping cloth 17 is released for a section, and the transmission gear 2 moves to the tail end of the tooth plate 41 and separates from the tooth plate 41. At this time, the mounting roller 16 will not release the material. When one side of the circular camera 44 moves to the inner side of the long nozzle 19, one side of the moving plate 51 contacts one end of the piston rod 33, and the driving plate 14 brings the camera base 5 and the circular camera 44 to move continuously. The piston rod 33 will be pushed into the inner cavity of the piston cylinder 35 to move, and the cleaning agent in the inner cavity of the piston cylinder 35 will be pushed into the long nozzle 19 through the water pipe 34 for spraying. In the spraying process, the circular camera 44 is continuously moving, so that the cleaning agent can be evenly sprayed on the circular camera 44. The surface, with the continuous movement of the moving plate 51, will move to the smooth section at the end of the driving screw 15. At this time, the driving screw 15 can no longer drive the moving plate 51 to move. The driving plate 14 continues to move. A touch switch can be installed at the end of the driving plate 14. When the driving plate 14 contacts the passive plate 31, the circular camera 44 is just moved between the two semicircular cleaning plates 18. At this time, the driving motor 6 starts to control the two-way screw 7 to rotate, and then drives the two pushing frames 60 to move closer to each other to push the semicircular cleaning plates 18 to move. The movement of the semicircular cleaning plates 18 pushes the wiping cloths 17 on both sides of the circular camera 44 to wrap around the circular camera 44.

[0054] The driving plate 14 continues to move to push the passive plate 31 to slide on the guide rod 49, and at the same time drives the top plate 58 to move. The top plate 58 drives the upper fixed plate 10 and the lower mounting plate 9 to move. When the upper fixed plate 10 moves, the bevel gear 11 contacts the helical racks 12 on both sides of it in turn, and the helical rack 12 on the left side of the bevel gear 11 rotates clockwise, and the helical rack 12 on the right side of the bevel gear 11 drives the bevel gear 11 to rotate in the opposite direction, thereby driving the rotating column 13 to drive the top plate 58 to rotate repeatedly, thereby making the semicircular cleaning plate 18 carry the wiping cloth 17 to reciprocate on the circular camera 44 to achieve automatic wiping, and the wiping effect is good. The semicircular cleaning plate 18 will not contact the guide rod 49 when rotating, and the rotation range is limited, thereby storing the circular camera 44 in the inner cavity of the protective shell 1 for protection, and realizing self-cleaning at the same time. After cleaning, start the driving motor 6 to drive the bidirectional screw 7 to rotate, so that the two semicircular cleaning plates 18 can be separated;

[0055] Through the cooperation of the second spring 57 and the first push spring 54, when the driving plate 14, the camera base 5 and the circular camera 44 completely enter the inner cavity of the protective housing 1, the first push spring 54 pushes the closing door 55 to move, and the second spring 57 pushes the closing plate 20 to move, so as to close the inner cavity of the protective housing 1;

[0056] When the circular camera 44 needs to be protected in a harsh environment or the circular camera 44 must work, the driving screw 15 rotates in the opposite direction to drive the driving plate 14 to move outward. At this time, the driving plate 14 moves to the right, and the top plate 58 is also slowly reset under the action of the limiting telescopic rod 37 and the reset spring. The limiting telescopic rod 37 and the reset spring can not only realize the automatic reset of the cleaning mechanism, but also support and limit the position of the top plate 58.

[0057] Since a one-way bearing is provided between the worm 4 and the transmission gear 2, when the tooth plate 41 is reset, the one-way bearing rotates, and the worm wheel 59 will not be driven to rotate, and the installation roller 16 will not run, so that the installation roller 16 is prevented from rolling up the dirty wiping cloth 17, thereby improving stability;

[0058] At this time, the electromagnet 48 is turned off and the conical electromagnet block 43 is turned on. When the conical electromagnet block 43 contacts the circular camera 44 on the inner side of the closed door 55, the conical electromagnet block 43 generates a magnetic attraction, which is then adsorbed with the metal sheet on the inner wall of the inclined groove 56, and the closed door 55 cannot be pushed to move to the sides. At this time, the electromagnet 48 will not have a fixing effect on the transparent frame 47, so that the closed door 55 and the transparent frame 47 move with the camera base 5. Since the transparent frame 47 and the closed door 55 are basically made of transparent materials, the camera requirements of the circular camera 44 can be greatly met. Although there is partial obstruction, the impact is not significant. The transparent frame 47 and the closed door 55 are used to protect the circular camera 44, and at the same time, the use of the circular camera 44 is not affected. It can be used normally in some harsh environments to avoid damage to the circular camera 44.

[0059] At the same time, during the outward movement of the driving plate 14, the traction belt 50 on one side of the push plate 40 will be initially straightened. When it is stretched to the limit, the traction belt 50 will pull the movable plate 51 to move to the right, and then it will re-match with the thread on the driving screw 15. At this time, the movable plate 51 and the push plate 40 move synchronously, and the traction belt 50 on the left side of the movable plate 51 will be initially straightened and then pull the piston rod 33 to move to the right. At this time, the liquid in the inner cavity of the water tank 32 will be pumped into the inner cavity of the piston cylinder 35 through the water pipe 34. The one-way valve close to the water tank 32 can only allow the liquid to enter the inner cavity of the piston cylinder 35 from the water pipe 34, while the one-way valve close to the long strip nozzle 19 can only release water but not let in water, thereby realizing automatic absorption and automatic spraying of the cleaning agent;

[0060] When some plastic bags or bags used by illegal personnel are put on the external reinforcement tube 3, making the circular camera 44 unable to take pictures, the driving motor 29 can be started to drive the gear 1 22 to rotate and then drive the inner gear ring 23 to rotate, and the inner gear ring 23 is used to drive the two sets of mounting rods 25 to rotate. When the mounting rods 25 rotate, one of the passive gears 28 is meshed with the half gear ring 1 39, and the other passive gear 28 is meshed with the half gear ring 2 8, which will drive the slider 24 to rotate, and then cooperate with the reciprocating screw rod 26 to push the cleaning blade 27 out;

[0061] Since the half gear ring 1 39 and the half gear ring 2 8 are two opposite half gear rings, when the driven gear 28 and the half gear ring 2 8 move halfway along the inner wall of the half gear ring 1 39 and the half gear ring 2 8, the cleaning blade 27 is pushed out to the limit position, and the slider 24 is at the end of the reciprocating screw rod 26. When the rotation continues, the two driven gears 28 contact the half gear ring 1 39 and the half gear ring 2 8 without teeth. The driven gear 28 will not continue to rotate, but the two cleaning blades 27 rotate half a circle respectively, which is a total rotation of one circle. The plastic bag and cloth sleeved on the end of the external reinforcement tube 3 can be cut, and the cleaning blade 27 can also scratch or push off the plastic bag and cloth when it is extended, so that automatic cleaning can be achieved. After the inner gear ring 23 rotates one circle, the passive gear 28 continues to mesh with the teeth on the half gear ring 1 39 and the half gear ring 2 8, and the inner gear ring 23 rotates another circle to make the slider 24 continue to rotate. Since the reciprocating screw 26 is a reciprocating screw, the cleaning blade 27 is retracted into the inner cavity of the mounting rod 25 to form a reset. The inner gear ring 23 needs to rotate at least two circles for each use.
