Description

Technical Field

[0001] The present invention relates to the technical field of security equipment, and in particular to an Internet of Things operation and maintenance monitoring camera device. Background Art

[0002] A surveillance camera is a device used in the security field. It is a semiconductor imaging device and is mainly used for recording videos and capturing images. Its principle is: after the surveillance camera captures images and sounds, the optical fiber transceiver converts the electrical signal on the surveillance camera at the transmitting end (TX) into an optical signal, and transmits it to the receiving end (RX) through the optical fiber. The receiving end (RX) converts the optical signal back into an electrical signal for display and storage on the surveillance device. In order to expand the monitoring range of the surveillance camera, the surveillance camera usually has a steering function. During the steering process, the surveillance camera will pull the connection between the surveillance camera and the optical fiber, which is prone to poor contact.

[0003] Chinese patent CN218162620U announced an IoT security protection monitoring camera device, including an installation box, a camera body, an IoT control system and a cooling component; a temperature sensor is provided in the installation box; the cooling component includes a water spray structure, which is provided on the upper side of the installation box, and the water spray structure includes a first driving member, a nozzle, a connecting pipe and a water pipe, one side of the connecting pipe is connected to the nozzle, and the other side of the connecting pipe is rotatably connected to the water pipe; the water pipe is connected to an external water source, and a solenoid valve is provided on the connecting pipe, and the temperature sensor, the first driving member and the solenoid valve are electrically connected to the IoT control system respectively; the first driving member is used to drive the nozzle to rotate, and the rotation center of the connecting pipe coincides with the rotation center of the first driving member. The temperature in the installation box is monitored by the temperature sensor, and when the temperature is too high, the cooling component is started, and the water spray structure sprays water to the top of the installation box, thereby achieving cooling.

[0004] At present, most of the monitoring camera equipment mentioned in the prior art have been improved in aspects such as dirt removal and heat dissipation, but the problem of poor contact between the monitoring camera and the optical fiber connection due to wear has been ignored. Most monitoring camera devices have a steering function. During the steering process of the monitoring camera, there will be shear force at the connection between the monitoring camera and the optical fiber, which causes the optical fiber connector to constantly shake at the connection during the steering process. The existing solution is to install a fixed sleeve at the connection to limit the shaking of the optical fiber connector. Although this method can alleviate the shaking problem, after the monitoring camera has been rotated for a long time, the fixed sleeve will be worn and aged, and the optical fiber connector will continue to shake at the connection, resulting in poor contact, which will lead to interruption of the monitoring picture or unclear monitoring picture, affecting the normal use of the monitoring equipment and easily missing important information.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In order to solve the technical problem that after the monitoring camera 2 rotates for a long time, the connector 62 on the optical fiber 6 will shake inside the slot 42, resulting in poor contact, which will cause the monitoring picture to be interrupted or unclear, such as Figure 1 - Fig.14 As shown, the following preferred technical solutions are provided: An Internet of Things operation and maintenance monitoring camera device comprises a mounting frame 1 and a monitoring camera 2 movably mounted on the mounting frame 1. The mounting frame 1 is used to mount the monitoring camera 2 at a specified position. The monitoring camera 2 is used to perform video recording and picture capture. A mounting plate 3 is fixedly arranged on the back of the monitoring camera 2. The mounting plate 3 can support and fix many components. A wiring assembly 4 is fixedly arranged on the outer wall of the mounting plate 3. An optical fiber 6 is plugged into the wiring assembly 4. A protective cover 5 is fixedly arranged on the outer wall of the mounting plate 3 to protect the components inside the protective cover 5 and extend the service life of the monitoring camera device. A fixing sleeve 7 is sleeved on the optical fiber 6. A plurality of adsorption components 30 are arranged inside the fixing sleeve 7, and the adsorption components 30 can be adsorbed on the outer wall of the wiring assembly 4. When the optical fiber 6 is inserted into the wiring assembly 4, the fixing sleeve 7 is fitted on the outer wall of the wiring assembly 4, and then the adsorption component 30 is started to adsorb the fixing sleeve 7 on the outer wall of the wiring assembly 4, so as to enhance the connection stability between the wiring assembly 4 and the optical fiber 6. A driving component 8 and a rotating component 9 are also arranged on the outer wall of the mounting plate 3, respectively. The driving component 8 and the rotating component 9 are meshedly connected. A pressing component 10 is fixedly installed on the outer wall of the rotating component 9, and a plurality of pushing components 20 are fixedly arranged on the outer peripheral wall of the wiring assembly 4.

[0022] As the surveillance camera 2 rotates, shear force will be generated between the wiring assembly 4 and the optical fiber 6. Although the fixing sleeve 7 limits the shaking of the optical fiber 6, after the surveillance camera device has been used for a long time, the fixing sleeve 7 will be worn and aged, and the optical fiber 6 and the wiring assembly 4 will still shake, resulting in poor contact, which will lead to the problem that the surveillance image cannot be displayed normally. At this time, the adsorption assembly 30 is closed so that the fixing sleeve 7 is no longer adsorbed on the outer wall of the wiring assembly 4, and then the driving assembly 8 is started. Since the driving assembly 8 and the rotating assembly 9 are meshed and connected, the driving assembly 8 will drive the rotating assembly 9 to rotate synchronously during the rotation process. At this time, the pressing assembly 10 is started to slide in the direction close to the propulsion assembly 20. When the pressing assembly 10 contacts the propulsion assembly 20, the pressing assembly 10 continues to slide and applies pressure to the propulsion assembly 20, so that the propulsion assembly 20 and the outer wall of the fixed sleeve 7 are in contact. The outer wall of the wiring assembly 4 contacts each other and applies pressure to the fixing sleeve 7. Since the adsorption component 30 is closed, the fixing sleeve 7 is no longer adsorbed on the outer wall of the wiring assembly 4. Then, after the fixing sleeve 7 is subjected to the pressure of the pushing component 20, it will translate on the outer wall of the wiring assembly 4. During the translation of the fixing sleeve 7, the optical fiber 6 will be driven to shake inside the wiring assembly 4, and the plugging angle of the optical fiber 6 inside the wiring assembly 4 will be adjusted until the plugging angle of the optical fiber 6 and the wiring assembly 4 is adjusted to a good contact and the monitoring screen is restored to normal. At this time, the adsorption component 30 is started to adsorb the fixing sleeve 7 on the outer wall of the wiring assembly 4 to fix the adjusted plugging angle to maintain a good contact effect in the future. Moreover, the pressing component 10 can rotate with the rotating component 9, which enables the pressing component 10 to adjust the plugging angle of the optical fiber 6 at multiple angles through the pushing component 20 and the fixing sleeve 7, thereby enhancing the convenience and flexibility of use.

[0023] Several plug-in assemblies 40 and compression assemblies 50 are fixedly arranged inside the wiring assembly 4, and the plug-in assemblies 40 and the compression assemblies 50 are fixedly connected. When the monitoring screen still cannot be displayed normally after the plug-in angle of the optical fiber 6 inside the wiring assembly 4 is adjusted, the adsorption assembly 30 is closed again so that the fixed sleeve 7 is no longer adsorbed on the outer wall of the wiring assembly 4, and the pressing assembly 10 and the pushing assembly 20 are restored to their original positions, and then the plug-in assembly 40 is started to pull out the optical fiber 6 from the inside of the wiring assembly 4. During the operation, the plug-in assembly 40 will drive the compression assembly 50 to compress the gas. When the plug-in assembly 40 pulls out the optical fiber 6 from the inside of the wiring assembly 4, the compressed gas of the compression assembly 50 is released, and the optical fiber 6 and the inside of the wiring assembly 4 are cleaned by air blowing to prevent poor contact caused by dust. After the air blowing cleaning is completed, the plug-in assembly 40 drives the optical fiber 6 to be inserted into the inside of the wiring assembly 4, and then the plug-in angle of the optical fiber 6 inside the wiring assembly 4 is adjusted until the monitoring screen is adjusted to normal.

[0024] The wiring assembly 4 includes a connector 41 fixedly mounted on the outer wall of the mounting plate 3, a slot 42 is provided on the outer wall of the connector 41, a first contact 43 is fixedly mounted on the inner wall of the slot 42, a pair of square slots 44 are also provided on the outer wall of the connector 41, the two square slots 44 are arranged on the sides of the slot 42, and the two square slots 44 are arranged in symmetrical positions, the plug-in assembly 40 is embedded and fixedly mounted in the inner cavity of the square slot 44, an air duct 45 is also provided inside the connector 41, the air outlet end of the air duct 45 is connected and fixedly mounted with a first air valve 46, the air duct 45 and the slot 42 are connected via the first air valve 46, and the air inlet end of the air duct 45 is connected to the air outlet end of the compression assembly 50.

[0025] The optical fiber 6 includes a cable 61, one end of which is fixedly connected to a connector 62, and a second contact 63 is fixedly installed on the outer wall of the connector 62. The connector 62 can be inserted into the inner cavity of the slot 42. When the connector 62 is inserted into the inner cavity of the slot 42, the first contact 43 contacts the second contact 63, thereby realizing signal transmission.

[0026] The driving assembly 8 includes a motor 81 fixedly mounted on the outer side wall of the mounting plate 3 , and an output end of the motor 81 is fixedly connected to a driving gear 82 .

[0027] The rotating assembly 9 includes a support ring 91 fixedly mounted on the outer wall of the mounting plate 3, on which a driven gear 92 is rotatably mounted, and the driving gear 82 is meshedly connected with the driven gear 92. The motor 81 can drive the driven gear 92 to rotate synchronously through the driving gear 82.

[0028] The pressing assembly 10 includes a connecting plate 101 fixedly mounted on the outer wall of the driven gear 92, a first slide groove 102 is opened on the outer wall of the connecting plate 101, a slide plate 103 is slidably mounted in the inner cavity of the first slide groove 102, a pressing wheel 104 is rotatably mounted on the outer wall of the slide plate 103, the bottom surface of the slide plate 103 and the bottom wall of the inner cavity of the first slide groove 102 are fixedly connected via a buffer 105, the buffer 105 can play a buffering role during the movement of the slide plate 103 to prevent the slide plate 103 from colliding with the inner wall of the first slide groove 102 and causing damage to the equipment, a permanent magnet 107 is fixedly mounted on the top surface of the slide plate 103, an electromagnet 106 is fixedly mounted on the top wall of the inner cavity of the first slide groove 102, and the permanent magnet 107 and the electromagnet 106 are arranged in an aligned position.

[0029] The propulsion assembly 20 includes a support rod 201 fixedly mounted on the outer peripheral wall of the connecting member 41, and a second slide groove 202 is provided at one end of the support rod 201 away from the connecting member 41. A slider 203 is slidably mounted in the inner cavity of the second slide groove 202, and the side wall of the slider 203 is elastically connected to the side wall of the inner cavity of the second slide groove 202 by a first spring 204. A push rod 205 is slidably mounted on the slider 203, and the top of the push rod 205 is elastically connected to the top surface of the slider 203 by a second spring 206.

[0030] Specifically, during the rotation of the surveillance camera 2, a shear force will be generated between the connecting piece 41 and the connector 62, causing the connector 62 to tend to shake in the inner cavity of the slot 42. Although the fixing sleeve 7 limits the shaking of the connector 62, after the surveillance camera device has been used for a long time, the fixing sleeve 7 will be worn and aged, and there will be a wear gap between the fixing sleeve 7 and the connector 62. The connector 62 will still shake in the inner cavity of the slot 42, causing the first contact 43 and the second contact 63 to be misaligned, so that the first contact 43 and the second contact 63 cannot be fully contacted, resulting in poor contact, which will lead to the problem that the surveillance screen cannot be displayed normally. At this time, the adsorption component 30 is closed so that the fixing sleeve 7 is no longer adsorbed on the outer wall of the wiring component 4, and then the motor 81 is started. The motor 81 drives the driven gear 92 to rotate synchronously on the support ring 91 through the driving gear 82.

[0031] When the driven gear 92 is rotating, the pressing component 10 will rotate synchronously with the driven gear 92. At this time, the electromagnet 106 is energized, so that the magnetism of the electromagnet 106 and the permanent magnet 107 are opposite, thereby pushing the slide plate 103 to slide with the pressure wheel 104 in the direction close to the push rod 205. When the pressure wheel 104 contacts the top of the push rod 205, the slide plate 103 continues to slide with the pressure wheel 104, and the pressure wheel 104 applies pressure to the top of the push rod 205, so that the push rod 205 slides on the slider 203 in the direction close to the fixed sleeve 7. When the push rod 205 contacts the outer peripheral wall of the fixed sleeve 7 and applies pressure to the fixed sleeve 7, the adsorption component 30 is closed, so that the fixed sleeve 7 is no longer adsorbed on the outer wall of the wiring component 4. Then, after the fixed sleeve 7 is pressed by the push rod 205, , will translate on the outer wall of the connecting piece 41. Due to the wear gap between the fixing sleeve 7 and the joint 62, the fixing sleeve 7 will drive the joint 62 to shake slightly in the inner cavity of the slot 42 during the translation process, and the plug-in angle of the joint 62 will be fine-tuned. Since the pressing component 10 can rotate with the driven gear 92, the pressing wheel 104 can continuously apply pressure to different ejector rods 205, so as to adjust the plug-in angle of the joint 62 in the inner cavity of the slot 42 at multiple angles, until the first contact 43 and the second contact 63 are restored from the misaligned state to the fully contacted state, and the monitoring screen can be restored to normal. At this time, the adsorption component 30 is started to adsorb the fixing sleeve 7 on the outer wall of the connecting piece 41 to fix the adjusted plug-in angle to maintain a good contact effect in the future.

[0032] By adjusting the insertion angle of the connector 62 in the inner cavity of the slot 42 at multiple angles, it is possible to achieve a troubleshooting effect. When the image of the monitoring device is interrupted or unclear, maintenance personnel can remotely determine whether it is due to shaking between the connector 62 and the slot 42, resulting in poor contact between the first contact 43 and the second contact 63, which in turn causes the monitoring image to fail to display normally. In addition, through the above-mentioned settings, when the monitoring image is unclear or interrupted, there is no need for maintenance personnel to immediately go to the site for maintenance, and the angle can be adjusted remotely, which greatly saves outdoor maintenance time. There is no need for maintenance personnel to climb to a high place for adjustment and maintenance, thereby reducing the risk of injury to maintenance personnel.

[0033] In order to solve the technical problem that after the angle adjustment of the connector 62 in the slot 42 is completed, the angle positioning cannot be achieved, and the connector 62 still shakes inside the slot 42 when the surveillance camera 2 rotates, as shown in FIG. Figure 3 - Figure 4 and Fig.14 As shown, the following preferred technical solutions are provided: The fixing sleeve 7 includes a sleeve 71 sleeved on the joint 62 , and a pair of circular grooves 72 are formed on the side wall of the sleeve 71 facing the connecting member 41 .

[0034] The adsorption assembly 30 includes an electric telescopic column 301 fixedly mounted on the inner wall of the circular groove 72, an air cylinder 302 fixedly mounted on the peripheral wall of the inner cavity of the circular groove 72, a first piston 303 slidably mounted inside the air cylinder 302, the first piston 303 is fixedly connected to the output end of the electric telescopic column 301, and a suction cup 304 is fixedly mounted on the outer wall of the air cylinder 302.

[0035] Specifically, after the connector 62 is inserted into the slot 42, the electric telescopic column 301 is started to drive the first piston 303 to retract into the circular groove 72. When the first piston 303 slides inside the air cylinder 302, the air in the suction cup 304 is sucked out, so that the inside of the suction cup 304 is in a negative pressure state, thereby making the sleeve 71 firmly adsorbed on the outer wall of the connector 41, so as to enhance the connection stability between the connector 62 and the slot 42; in addition, when the maintenance personnel adjust the insertion angle of the connector 62 in the slot 42 through the driving component 8, the rotating component 9, the pressing component 10 and the pushing component 20, the electric telescopic column 301 is started to drive the first piston 303 to retract into the circular groove 72. A piston 303 extends outward from the circular groove 72, canceling the negative pressure environment in the suction cup 304, allowing the sleeve 71 to slide on the outer wall of the connector 41, thereby enabling the adjustment of the plug-in angle of the connector 62. When the plug-in angle of the connector 62 is adjusted, the electric telescopic column 301 is started again to drive the first piston 303 to retract toward the inside of the circular groove 72, turning the inside of the magnetic suction cup 304 into a negative pressure state, and firmly adsorbing the sleeve 71 on the outer wall of the connector 41 again, so as to fix the adjusted plug-in angle, prevent poor contact from occurring again during the rotation of the surveillance camera 2, and ensure the operating stability of the adjusted surveillance device.

[0036] In order to solve the technical problem that the first contact 43 and the second contact 63 are in poor contact due to dust, thereby causing the monitoring image to be interrupted or the image to be unclear, as shown in FIG. Figure 7 - Figure 8 and Fig.12 - Fig.13 As shown, the following preferred technical solutions are provided: The plug-in assembly 40 includes a telescopic rod 401 embedded and fixedly installed on the side wall of the inner cavity of the square groove 44, an electric push rod 402 is fixedly installed on the side wall of the telescopic rod 401 facing the sleeve 71, and the output end of the electric push rod 402 is movably connected with a clamping plate 403, and a pressure sensor 404 is provided on the side wall of the clamping plate 403 facing the sleeve 71. When the clamping plate 403 passes through the side wall of the sleeve 71, there is enough gap between the clamping plate 403 and the side wall of the sleeve 71, so that when the insertion angle of the connector 62 inside the slot 42 is adjusted, the normal sliding of the sleeve 71 on the outer wall of the connecting piece 41 will not be restricted.

[0037] The compression assembly 50 includes a compression cylinder 501 fixedly mounted on the inner cavity side wall of the square groove 44, a compression member 502 is slidably arranged in the inner cavity of the compression cylinder 501, the top end of the compression member 502 is fixedly connected to the bottom surface of the extended end of the telescopic rod 401, and a one-way air inlet valve 503 and a one-way air outlet valve 504 are respectively fixedly mounted on the top surface of the compression cylinder 501, a second air valve 506 is fixedly mounted on the inner cavity side wall of the square groove 44, the one-way air outlet valve 504 and the second air valve 506 are connected via an air pipe 505, and the air inlet end of the airway 45 and the second air valve 506 are connected.

[0038] Specifically, when the monitoring screen still cannot be displayed normally after adjusting the insertion angle of the joint 62 in the slot 42, the electric telescopic column 301 is started to drive the first piston 303 to extend toward the outside of the circular groove 72, canceling the negative pressure environment in the suction cup 304, so that the suction cup 304 is no longer adsorbed on the outer wall of the connecting piece 41, and the pressing component 10 and the pushing component 20 are restored to their original positions, and then the electric push rods 402 on both sides are started to move the clamping plate 403 toward the direction close to the joint 62 until the clamping plate 403 clamps the joint 62 and applies pressure to the joint 62, so that the joint 62 and The clamping relationship between the slots 42 is released. During this process, the clamping force is monitored by the pressure sensor 404 to prevent the clamping force from being too large and damaging the joint 62. After the clamping plate 403 clamps the joint 62, the telescopic rod 401 begins to extend and pulls the joint 62 out of the slot 42. During the operation, the telescopic rod 401 drives the compression member 502 to slide inside the compression cylinder 501 to compress the gas inside the compression cylinder 501. When the joint 62 is pulled out from the slot 42, the one-way air outlet valve 504, the second air valve 506 and the first air valve 46 are opened, and the compressed gas inside the compression cylinder 501 is compressed. The air is released into the air passage 45 through the one-way air outlet valve 504, the air pipe 505 and the second air valve 506, and then discharged from the first air valve 46 at the air outlet end of the air passage 45, and the second contact 63 on the connector 62 and the first contact 43 inside the slot 42 are cleaned by air blowing to prevent the first contact 43 and the second contact 63 from poor contact due to dust. After the air blowing cleaning is completed, the telescopic rod 401 begins to retract, and synchronously drives the connector 62 to be inserted into the slot 42, and restores the card connection relationship between the connector 62 and the slot 42. The card connection principle between the connector 62 and the slot 42 is consistent with the card connection principle between the computer and the network cable. This will not be elaborated in detail. During the retraction of the telescopic rod 401, the compression member 502 will be driven to slide in the opposite direction inside the compression cylinder 501, and the outside air will be sucked into the interior of the compression cylinder 501 through the one-way air inlet valve 503, so as to be used for the next air blowing cleaning. When the connector 62 is inserted into the slot 42, the electric push rod 402 moves with the clamping plate 403 in the direction away from the connector 62, losing the clamping effect on the connector 62, and then the insertion angle of the optical fiber 6 inside the wiring assembly 4 is adjusted by the driving assembly 8, the rotating assembly 9, the pressing assembly 10 and the pushing assembly 20 until the monitoring screen is adjusted to normal.

[0039] Through the above-mentioned arrangement, after adjusting the insertion angle of the connector 62 in the slot 42, if the monitoring screen still cannot be displayed normally, the connector 62 is pulled out from the inside of the slot 42 through the plug-in assembly 40, and then the second contact 63 on the connector 62 and the first contact 43 in the slot 42 are blown clean by the high-pressure gas generated by the compression assembly 50. After cleaning, the connector 62 is plugged into the inside of the slot 42 through the plug-in assembly 40. Such operation can prevent poor contact between the first contact 43 and the second contact 63 caused by dust. In addition, maintenance personnel can immediately perform plug-in and pull-out operations and air blow cleaning operations on the connector 62 remotely, which can not only eliminate the fault, but also eliminate the need for maintenance personnel to rush to the site for debugging immediately, thereby achieving the purpose of saving time and effort, and the troubleshooting efficiency of the sending end of the monitoring camera device is high.
