Description

Technical Field

[0001] The invention belongs to the technical field of security monitoring cameras, and in particular relates to a miniature security monitoring electronic camera module. Background Art

[0002] Security cameras are a common device used to protect public safety and private property. They can be used in various places, such as stores, offices, schools, airports, banks, etc. Security cameras are mainly used to monitor and record the surrounding environment in real time, and provide video images for security personnel to observe and analyze. By installing cameras, you can improve safety awareness, prevent criminal behavior and track the process of incidents. At the same time, it also allows staff to better understand the situation at the work site and improve work efficiency.

[0003] Security monitoring electronic cameras are an important image monitoring equipment, widely used in various fields, providing us with convenience and safety. There are various types of security monitoring cameras on the market, but many security monitoring cameras still have many problems in actual use. During the operation, security monitoring cameras need to monitor the image information of the specified area in real time. In order to ensure the quality of the monitoring image, it is necessary to ensure the cleanliness of the monitoring lens. However, many micro-surveillance cameras do not have automatic cleaning functions. When they are installed and fixed on the wall or placed in a fixed position, as time goes by, a large amount of floating dust is easily attached to the surface of the lens. If the air in the installation area is relatively humid, dust will even solidify on the surface of the lens to form hard lumps. Once the surface of the lens is covered with floating dust, it will greatly affect the quality of the monitoring image. When the image data needs to be called, there will be certain defects, and it may even be unusable because the image data is relatively blurred; in addition, if the lens is cleaned manually on a regular basis, it will not only be time-consuming and labor-intensive, but also increase labor costs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a micro security monitoring electronic camera module.

[0005] The technical solution adopted to solve the above technical problems is: a micro security monitoring electronic camera module, including a bottom support mechanism, the top center of the bottom support mechanism is rotatably connected to a horizontal rotation mechanism, and the top of the horizontal rotation mechanism is fixedly connected to a rotation support mechanism;

[0006] The rotating support mechanism is rotatably connected with a mounting and positioning mechanism, a monitoring camera mechanism is installed in the mounting and positioning mechanism, and a second servo motor corresponding to the mounting and positioning mechanism is installed in the rotating support mechanism, and the mounting and positioning mechanism is driven by the second servo motor to rotate;

[0007] The horizontal rotating mechanism is also equipped with a main circuit board corresponding to the rotating support mechanism, the monitoring camera mechanism and the second servo motor;

[0008] A hard dust scraping mechanism corresponding to the mounting and positioning mechanism is fixedly installed at the top center of the rotating support mechanism, and the hard dust scraping mechanism is used to scrape hard dust attached to the surface of the mounting and positioning mechanism;

[0009] An automatic cleaning mechanism for cleaning dust on the surface of the mounting and positioning mechanism is installed at the rear center of the rotating support mechanism.

[0010] Furthermore, the bottom supporting mechanism includes a supporting base, an inner supporting frame is provided on the inner side of the supporting base, a rotating bearing is installed at the bottom of the inner wall of the inner supporting frame, a removable bottom cover plate is installed at the bottom of the supporting base, a plurality of bottom mounting holes are opened on the bottom periphery of the bottom cover plate, a magnetic ring is also installed at the bottom of the bottom cover plate, a silicone pad is also bonded to the bottom edge of the supporting base, and the bottom planes of the magnetic ring and the silicone pad are flush.

[0011] Through the above technical solution, the bottom support mechanism mainly plays a supporting role, and the bottom cover can be fixed to the support base by screws; in addition, a magnetic ring is installed at the bottom of the bottom cover, and when the camera needs to be installed on a metal body, it can be quickly installed and fixed by magnetic attraction; a silicone pad is also bonded to the bottom edge of the support base, and when the camera needs to be placed horizontally in a certain position, the silicone pad can play a certain anti-slip role to ensure stability during use, and will not shake violently even if it is collided.

[0012] Furthermore, the horizontal rotation mechanism includes a rotating seat installed between the inner support frame and the rotating bearing, a threading hole is opened at the center of the top of the rotating seat, a plurality of mounting columns are arranged on the circumferential side of the inner surface of the top of the rotating seat, a connecting part is installed at the bottom of the rotating seat, an integrated outer gear ring is arranged at the bottom of the connecting part, a mounting seat is also arranged on the inner support frame, a first servo motor is installed on the mounting seat, a driving gear meshing with the outer gear ring is installed on the output shaft of the first servo motor, and a plurality of heat dissipation holes are opened at the rear end of the rotating seat.

[0013] Through the above technical solution, the horizontal rotation mechanism is used to drive the camera to rotate 360 ​​degrees in a horizontal state. When the first servo motor is started, the output shaft of the first servo motor can drive the driving gear to rotate synchronously, and then drive the connecting part and the rotating seat to rotate through the engagement between the gears, so that the camera can adjust the monitoring angle of 360 degrees according to actual monitoring needs, avoiding the existence of monitoring blind spots.

[0014] Furthermore, the rotating support mechanism includes a supporting shell fixed to the top of the rotating seat, positioning shells are provided on both sides of the outer wall of the supporting shell, end covers are buckled on the outer sides of the two positioning shells, wiring grooves that are connected to the positioning shells are opened on both sides of the inner wall of the supporting shell, and a through hole is opened in the center of the rear end of the supporting shell.

[0015] Through the above technical solution, the rotating support mechanism can play a role of rotating support for the installation and positioning mechanism. The installation and positioning mechanism can rotate 360 ​​degrees in the vertical direction on the supporting shell, which not only increases the monitoring area of ​​the camera, but also facilitates the automatic cleaning of the monitoring lens through rotation.

[0016] Furthermore, the installation and positioning mechanism includes a spherical shell, and positioning shafts are provided in the center of both sides of the outer wall of the spherical shell. The two positioning shafts are respectively rotatably connected to the corresponding positioning shells, and the second servo motor is installed in one of the positioning shells, and the output end of the second servo motor is fixed to the positioning shaft at the corresponding position, and the front end of the inner wall of the spherical shell is also fixedly connected to a positioning seat.

[0017] Through the above technical solution, the spherical shell serves as an installation and positioning structure, mainly as an installation carrier, which can play a role in installing and positioning the surveillance camera mechanism. At the same time, the spherical shell can rotate freely between the positioning shells through two positioning shafts. Driven by the second servo motor, the spherical shell can rotate 360 ​​degrees in the vertical direction with the two positioning shafts as fulcrums, thereby driving the surveillance camera mechanism to rotate synchronously.

[0018] Furthermore, the monitoring camera mechanism includes a probe module installed in a positioning seat, and a connecting wire electrically connected to the main circuit board is connected to the rear end of the probe module.

[0019] Through the above technical solution, the probe module can perform normal monitoring during the working process, and convert the monitored image information into electrical signals, which are transmitted to the main circuit board through connecting wires. After the signal is processed by the main circuit board, it is transmitted to the computer display terminal through external wires. Its principle is the same as the working principle of existing conventional surveillance cameras.

[0020] Furthermore, the hard dust scraping mechanism includes an arc-shaped mounting frame fixed on a supporting shell, a spherical shovel is provided on the inner wall of the arc-shaped mounting frame, the cross-section of the spherical shovel is designed as a shovel-shaped structure, and the bottom of the spherical shovel is tightly fitted with the outer surface of the spherical shell.

[0021] Through the above technical solution, a large amount of floating dust will adhere to the outer surface of the spherical shell during the long-term use of the camera. When the air humidity in the area is high, some of the floating dust will solidify on the outer surface of the spherical shell due to moisture. The solidified dust has stronger adhesion and is therefore difficult to be directly cleaned by an automatic cleaning mechanism. Therefore, an arc-shaped mounting frame is provided on the support shell, and a spherical shovel is arranged on the arc-shaped mounting frame. Since the bottom of the spherical shovel fits tightly with the outer surface of the spherical shell, the spherical shovel with a shovel-shaped structure can easily remove the dust solidified on the surface of the spherical shell when the spherical shell is directional rotated, thereby achieving pre-cleaning, so as to facilitate the subsequent automatic cleaning mechanism to further wipe and clean the floating dust on its surface, so as to ensure the cleanliness of the spherical shell surface.

[0022] Furthermore, the automatic cleaning mechanism includes an installation shell fixed on the rear end surface of the supporting shell, and both sides of the inner wall of the installation shell are provided with limit slide grooves, a detachable installation frame is slidably connected in the installation shell, and both sides of the outer wall of the detachable installation frame are fixedly connected with limit sliders, and the limit sliders are slidably limited in the corresponding limit slide grooves, and the two sides of the detachable installation frame near the front end are respectively rotatably connected with a first drum-shaped rotating bracket and a second drum-shaped rotating bracket, and the detachable installation frame is also rotatably connected with a cloth placing roller and a cloth collecting roller near the middle position. The outer wall of the cloth-releasing roller is wrapped with clean non-woven fabric. During use, one end of the non-woven fabric passes around the first drum-shaped rotating bracket and the second drum-shaped rotating bracket, and is wrapped and fixed on the cloth-collecting roller. A detachable first cover plate is installed at the rear end of the installation shell, and an extrusion block is also installed on the inner wall of the front end of the first cover plate. The extrusion block is used to squeeze the non-woven fabric to ensure the tension of the non-woven fabric during the releasing process. The bottom of the installation shell is fixedly connected to a bottom shell, and a winding motor connected to the cloth-collecting roller is installed in the bottom shell, and a detachable second cover plate is installed at the bottom of the bottom shell.

[0023] Through the above technical solution, when the spherical shell needs to be rotated to clean the floating dust, the spherical shell will rotate autonomously under the drive of the second servo motor. Since the detachable mounting frame is equipped with a non-woven fabric that can be automatically adjusted and retracted, and the non-woven fabric is tightly fitted with the surface of the spherical shell, the surface of the spherical shell can generate friction with the non-woven fabric during the rotation process, so that the floating dust attached to the surface of the spherical shell can be wiped off with the non-woven fabric, thereby achieving the purpose of automatic cleaning of the lens; further, since the bottom end of the cloth-collecting roller is connected to the output shaft of the winding motor, during the automatic wiping and cleaning process of the lens, the winding motor can drive the cloth-collecting roller to rotate, and then can pull the cloth-collecting roller to rotate. The non-woven fabric on the cloth-feeding roller is constantly moved and released, so that the monitoring lens part on the surface of the spherical shell can be better wiped; in addition, an extrusion block is also installed on the inner wall of the front end of the first cover plate, and the extrusion block can continuously squeeze the non-woven fabric wrapped around the outer wall of the cloth-feeding roller, so that the non-woven fabric can have a certain tension during the release process, and maintain a certain tension state, so as to prevent the spherical shell from causing the non-woven fabric to be too loose during the rotating wiping process, thereby affecting the wiping and cleaning effect; the extrusion block is made of elastic material, and it can produce a certain deformation itself, and exert a certain pressure on the wrapped non-woven fabric, and its material can be various types of elastic sponges.

[0024] Furthermore, during use, the non-woven fabric is deformed by contact with the spherical shell and fits tightly with the surface of the spherical shell.

[0025] Through the above technical solution, the non-woven fabric can be better fitted with the spherical shell, thereby achieving a better wiping and cleaning effect, and further ensuring the cleanliness of the surface of the spherical shell.

[0026] Furthermore, it also includes a detachable auxiliary mounting structure, which includes a mounting plate that can be installed and fixed to the bottom cover plate, and a plurality of inner mounting holes corresponding to the bottom mounting holes are opened at the bottom of the mounting plate, and a plurality of evenly distributed outer mounting holes are also opened at the edge of the mounting plate.

[0027] Through the above technical solution, when the camera module needs to be installed and fixed on the wall, the mounting plate can be first connected to the bottom cover plate through multiple fixing screws, and then installed and fixed on the wall through screws and multiple external mounting holes.

[0028] The beneficial effects of the present invention are as follows: (1) The present invention can quickly and automatically clean hard lumps and floating dust attached to the surface of the monitoring lens by designing a hard dust scraping mechanism and an automatic cleaning mechanism, which not only improves the cleaning efficiency and saves labor costs, but also ensures the clarity and quality of the monitoring image; (2) The present invention can easily scrape away the dust solidified on the surface of the spherical shell by designing a hard dust scraping mechanism, so as to achieve pre-cleaning, so as to facilitate the subsequent automatic cleaning mechanism to further wipe and clean the floating dust on the surface, thereby ensuring the cleanliness of the spherical shell surface; (3) The present invention can use non-woven fabric to wipe off the floating dust attached to the surface of the spherical shell by designing an automatic cleaning mechanism, thereby achieving the purpose of automatic lens cleaning and ensuring the cleanliness of the monitoring lens.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0049] like Figure 1-Figure 7 As shown, a micro security monitoring electronic camera module of this embodiment includes a bottom support mechanism 1, the bottom support mechanism 1 includes a support base 101, an inner support frame 102 is provided inside the support base 101, a rotating bearing 103 is installed at the bottom of the inner wall of the inner support frame 102, a removable bottom cover plate 104 is installed at the bottom of the support base 101, a plurality of bottom mounting holes 105 are opened on the bottom peripheral side of the bottom of the bottom cover plate 104, a magnetic ring 106 is also installed at the bottom of the bottom cover plate 104, a silicone pad 107 is also bonded to the bottom edge of the support base 101, and the magnetic ring 106 and The bottom plane of the silicone pad 107 is flat, and the bottom supporting mechanism 1 mainly plays a supporting role. The bottom cover 104 can be fixed to the supporting base 101 by screws; in addition, a magnetic ring 106 is installed at the bottom of the bottom cover 104. When the camera needs to be installed on a metal body, it can be quickly installed and fixed by magnetic attraction; a silicone pad 107 is also bonded to the bottom edge of the supporting base 101. When the camera needs to be placed horizontally in a certain position, the silicone pad 107 can play a certain anti-slip role to ensure stability during use, and will not shake violently even if it is hit.

[0050] like Figure 1-Figure 13 As shown, the top center of the bottom support mechanism 1 is rotatably connected to a horizontal rotation mechanism 2, and the horizontal rotation mechanism 2 includes a rotating seat 201 installed between the inner support frame 102 and the rotating bearing 103, a threading hole 202 is opened at the top center of the rotating seat 201, and a plurality of mounting columns 203 are arranged on the circumferential side of the inner surface of the top of the rotating seat 201, a connecting portion 204 is installed at the bottom of the rotating seat 201, and an integrated outer gear ring 205 is arranged at the bottom of the connecting portion 204, and a mounting seat 206 is also arranged on the inner support frame 102, and a first servo motor 207 is installed on the mounting seat 206, and the first servo motor A driving gear 208 meshing with the outer gear ring 205 is installed on the output shaft of 207, and a plurality of heat dissipation holes 209 are provided at the rear end of the rotating seat 201. The horizontal rotating mechanism 2 is used to drive the camera to rotate 360 ​​degrees in a horizontal state. When the first servo motor 207 is started, the output shaft of the first servo motor 207 can drive the driving gear 208 to rotate synchronously, and then the connecting part 204 and the rotating seat 201 can be driven to rotate through the meshing between the gears, so that the camera can adjust the monitoring angle 360 ​​degrees according to the actual monitoring needs, avoiding the existence of monitoring blind spots.

[0051] like Figure 12-13As shown, a rotating support mechanism 3 is fixedly connected to the top of the horizontal rotating mechanism 2, and the rotating support mechanism 3 includes a supporting shell 301 fixed to the top of the rotating seat 201, and positioning shells 302 are arranged on both sides of the outer wall of the supporting shell 301, and end covers 303 are buckled on the outer sides of the two positioning shells 302, and wiring grooves 304 that are connected to the positioning shells 302 are opened on both sides of the inner wall of the supporting shell 301, and a through hole 305 is opened at the rear end center of the supporting shell 301. The rotating support mechanism 3 can play a role of rotating support for the installation positioning mechanism 4, and the installation positioning mechanism 4 can be rotated 360 degrees in the vertical direction on the supporting shell 301, which not only increases the monitoring area of ​​the camera, but also facilitates the automatic cleaning of the monitoring lens through rotation.

[0052] like Figure 3-Figure 13 As shown, the rotating support mechanism 3 is rotatably connected with an installation and positioning mechanism 4, and the installation and positioning mechanism 4 includes a spherical shell 401. The centers of both sides of the outer wall of the spherical shell 401 are provided with positioning shafts 402. The two positioning shafts 402 are rotatably connected to the corresponding positioning shells 302 respectively. The second servo motor 6 is installed in one of the positioning shells 302, and the output end of the second servo motor 6 is fixed to the positioning shaft 402 at the corresponding position. The front end of the inner wall of the spherical shell 401 is also fixedly connected with a positioning seat 403. The spherical shell 401 serves as an installation and positioning structure, mainly as an installation carrier, which can play a role in installing and positioning the monitoring camera mechanism 5. At the same time, the spherical shell 401 can rotate freely between the positioning shells 302 through the two positioning shafts 402. Under the drive of the second servo motor 6, the spherical shell 401 can rotate 360 ​​degrees in the vertical direction with the two positioning shafts 402 as fulcrums, thereby driving the monitoring camera mechanism 5 to rotate synchronously.

[0053] like Figure 4 As shown, a monitoring camera mechanism 5 is installed in the installation positioning mechanism 4, and the monitoring camera mechanism 5 includes a probe module 501 installed in the positioning seat 403. The rear end of the probe module 501 is connected to a connecting wire 502 electrically connected to the main circuit board 7. The probe module 501 can perform normal monitoring during operation and convert the monitored image information into an electrical signal, which is transmitted to the main circuit board 7 through the connecting wire 502. After the signal is processed by the main circuit board 7, it is transmitted to the computer display terminal through an external wire. Its principle is the same as the working principle of an existing conventional monitoring camera.

[0054] A second servo motor 6 corresponding to the mounting and positioning mechanism 4 is installed in the rotation support mechanism 3 , and the mounting and positioning mechanism 4 is driven by the second servo motor 6 to rotate.

[0055] A main circuit board 7 corresponding to the rotation support mechanism 3 , the monitoring camera mechanism 5 and the second servo motor 6 is also installed in the horizontal rotation mechanism 2 .

[0056] like Figure 4-Figure 8 As shown, a hard dust scraping mechanism 8 corresponding to the mounting and positioning mechanism 4 is fixedly installed at the top center position of the rotating support mechanism 3. The hard dust scraping mechanism 8 is used to scrape off the hard dust attached to the surface of the mounting and positioning mechanism 4. The hard dust scraping mechanism 8 includes an arc-shaped mounting frame 801 fixed on the supporting shell 301. A spherical shovel 802 is provided on the inner wall of the arc-shaped mounting frame 801. The cross-section of the spherical shovel 802 is designed in a shovel-shaped structure, and the bottom of the spherical shovel 802 is tightly fitted with the outer surface of the spherical shell 401. During the long-term use of the camera, a large amount of floating dust will be attached to the outer surface of the spherical shell 401. When the air humidity in this area is high, some of the floating dust will be affected by moisture. The dust solidified on the outer surface of the spherical shell 401 has stronger adhesion and is therefore difficult to be cleaned directly by the automatic cleaning mechanism 9. Therefore, an arc-shaped mounting frame 801 is provided on the support shell 301, and a spherical shovel 802 is arranged on the arc-shaped mounting frame 801. Since the bottom of the spherical shovel 802 fits tightly with the outer surface of the spherical shell 401, the spherical shovel 802 with a shovel-shaped structure can easily remove the dust solidified on the surface of the spherical shell 401 when the spherical shell 401 is directional rotated, thereby achieving pre-cleaning, so as to facilitate the subsequent automatic cleaning mechanism 9 to further wipe and clean the floating dust on its surface, so as to ensure the cleanliness of the surface of the spherical shell 401.

[0057] like Figure 11-Figure 16As shown, an automatic cleaning mechanism 9 for cleaning dust on the surface of the mounting and positioning mechanism 4 is installed at the rear center of the rotating support mechanism 3. The automatic cleaning mechanism 9 includes a mounting shell 901 fixed on the rear end surface of the supporting shell 301. Both sides of the inner wall of the mounting shell 901 are provided with limit slide grooves 902. A detachable mounting frame 903 is slidably connected in the mounting shell 901. Both sides of the outer wall of the detachable mounting frame 903 are fixedly connected with limit slide blocks 904. The limit slide blocks 904 are slidably limited to the corresponding limit slide grooves 90 2, the two sides of the detachable mounting frame 903 near the front end are rotatably connected with the first drum-shaped rotating bracket 905 and the second drum-shaped rotating bracket 906 respectively, and the cloth-releasing roller shaft 907 and the cloth-collecting roller shaft 908 are rotatably connected near the middle position of the detachable mounting frame 903 respectively, and the outer wall of the cloth-releasing roller shaft 907 is wound with a clean non-woven fabric 909. During use, one end of the non-woven fabric 909 passes around the first drum-shaped rotating bracket 905 and the second drum-shaped rotating bracket 906, and is wound and fixed on the cloth-collecting roller shaft 908. A detachable first cover plate 910 is installed at the rear end of the installation shell 901, and an extrusion block 911 is also installed on the inner wall of the front end of the first cover plate 910. The extrusion block 911 is used to squeeze the non-woven fabric 909 to ensure the tension of the non-woven fabric 909 during the release process. A bottom shell 912 is fixedly connected to the bottom of the installation shell 901, and a winding motor 913 connected to the cloth collection roller 908 is installed in the bottom shell 912. A detachable second cover plate 914 is installed at the bottom of the bottom shell 912. When the spherical shell 401 needs to be When rotating to clean the floating dust, the spherical shell 401 will rotate autonomously under the drive of the second servo motor 6. Since the detachable mounting frame 903 is equipped with a non-woven fabric 909 that can be automatically adjusted and retracted, and the non-woven fabric 909 is tightly fitted with the surface of the spherical shell 401, the surface of the spherical shell 401 can generate friction with the non-woven fabric 909 during the rotation process, so that the non-woven fabric 909 can be used to wipe off the floating dust attached to the surface of the spherical shell 401, thereby achieving the purpose of automatic cleaning of the lens.

[0058] Furthermore, since the bottom end of the cloth collecting roller 908 is connected to the output shaft of the winding motor 913, during the automatic wiping and cleaning process of the lens, the winding motor 913 can drive the cloth collecting roller 908 to rotate, and then can pull the non-woven fabric 909 on the cloth placing roller 907 to continuously move and release, so that the monitoring lens part on the surface of the spherical shell 401 can be better wiped; in addition, an extrusion block 911 is also installed on the inner wall of the front end of the first cover plate 910, and the extrusion block 911 can continuously squeeze the non-woven fabric 909 wrapped around the outer wall of the cloth placing roller 907, so that the non-woven fabric 909 can have a certain tension during the release process and maintain a certain tension state, so as to prevent the spherical shell 401 from causing the non-woven fabric 909 to be too loose during the rotating wiping process, thereby affecting the wiping and cleaning effect; the extrusion block 911 is made of elastic material, and it can produce a certain deformation itself and exert a certain pressure on the non-woven fabric 909 in a wound state, and its material can be various types of elastic sponges.

[0059] During use, the non-woven fabric 909 is deformed by contact with the spherical shell 401 and fits tightly with the surface of the spherical shell 401, so that the non-woven fabric 909 can fit better with the spherical shell 401, thereby achieving a better wiping and cleaning effect, and further ensuring the cleanliness of the surface of the spherical shell 401.

[0060] Furthermore, the internal structure of the automatic cleaning mechanism 9 adopts a detachable structure design. When the non-woven fabric 909 inside is consumed, it can be disassembled and replaced according to actual usage.

[0061] like Figure 17-Figure 18 As shown, the camera module is also designed with a matching auxiliary mounting structure 10, and the auxiliary mounting structure 10 includes a mounting plate 1001 that can be installed and fixed with the bottom cover plate 104, and a plurality of inner mounting holes 1002 corresponding to the bottom mounting holes 105 are provided at the bottom of the mounting plate 1001, and a plurality of evenly distributed outer mounting holes 1003 are also provided at the edge of the mounting plate 1001. By designing a detachable auxiliary mounting structure 10, when the camera module needs to be installed and fixed on a wall, the mounting plate 1001 can be first connected to the bottom cover plate 104 through a plurality of fixing screws, and then installed and fixed on the wall through screws and a plurality of outer mounting holes 1003.

[0062] The working principle of this embodiment is as follows: the camera module can be placed in a fixed position for use, or it can be installed and fixed on a wall through an auxiliary mounting structure 10 for use. After the line connection is completed, it can be put into normal use;

[0063] When a large amount of floating dust or solidified floating dust adheres to the outer surface of the spherical shell 401 and needs to be cleaned, the spherical shell 401 can rotate in the vertical direction with the two positioning shafts 402 as fulcrums under the drive of the second servo motor 6, thereby driving the monitoring camera mechanism 5 to rotate synchronously. An arc-shaped mounting frame 801 is installed on the support shell 301, and a spherical shovel 802 is provided on the arc-shaped mounting frame 801. Since the bottom of the spherical shovel 802 is tightly fitted with the outer surface of the spherical shell 401, the spherical shovel 802 with a shovel-shaped structure can easily remove the dust solidified on the surface of the spherical shell 401 when the spherical shell 401 is directional rotated, thereby achieving pre-cleaning;

[0064] When the spherical shell 401 continues to rotate under the drive of the second servo motor 6, the lens part located at the front end of the spherical shell 401 will rotate to the position of the automatic cleaning mechanism 9 at the rear. Since the detachable mounting frame 903 is equipped with a non-woven fabric 909 that can be automatically adjusted and retracted, and the non-woven fabric 909 is tightly fitted with the surface of the spherical shell 401, the surface of the spherical shell 401 can generate friction with the non-woven fabric 909 during the rotation process, so that the non-woven fabric 909 can be used to wipe off the floating dust attached to the surface of the spherical shell 401, thereby achieving the purpose of automatic cleaning of the lens, and after cleaning is completed, the spherical shell 401 will automatically reset for normal monitoring.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
