Description

Technical Field

[0001] The present invention relates to the technical field of monitoring cameras, in particular to a concealed security monitoring camera. Background Art

[0002] Security monitoring refers to collecting image information through surveillance cameras, transmitting video signals in a closed loop through optical fiber, coaxial cable or microwave, and displaying and recording the images obtained by the camera.

[0003] The patent with the patent announcement number CN210246864U discloses a concealed security monitoring camera, including a support column, a support plate is fixedly connected to the side wall of the support column near the upper end through two fixing cards, a carrier plate is fixedly connected to the lower end of the support plate away from the support column, a camera and a protective cover are fixedly connected to the upper end of the carrier plate, the camera is located in the protective cover, the upper end of the protective cover is covered with a transparent glass cover, a reflector is connected to the side wall of the support plate near the upper end through an adjustment mechanism, the reflector is located directly above the camera, and a cleaning device is installed on the side of the support plate near the support column. The patent makes the device have a good concealed device, which is not easy to be discovered or even destroyed by the camera target, and can adjust the shooting range.

[0004] However, the device still has some shortcomings: the device uses a reflector to avoid being discovered by the target, but the flat top surface of the glass cover makes it easy for it to absorb outdoor rain or dew, and it makes it difficult for water to flow quickly, so it accumulates on the top surface of the glass cover for a long time. When the water droplets on the surface of the glass cover are exposed to sunlight, the light source is easily refracted. At this time, the camera's recording image is disturbed by the light source, resulting in blurred exposure. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a concealed security monitoring camera, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the present invention is implemented through the following technical solutions: a concealed security monitoring camera, including several support columns, several circular holes are opened on the outer walls of several support columns, a receiving plate is fixedly installed on the top of the support column, and slide grooves are opened at the front and back edges of the receiving plate. A rotating component is arranged at the center of the top of the receiving plate, and a motor is built into the rotating component. A protective cover is arranged on the top of the motor output end, and a recording component is arranged inside the protective cover. The recording component transmits information through a built-in wireless module, and a stabilizing seat is arranged on the inner side of the support column, a slide groove is opened on the top of the stabilizing seat, and the stabilizing seat is located directly below the receiving plate. An electric push rod is fixedly installed at the center of the top of the stable seat, and an I-shaped plate is fixedly installed on the top of the telescopic end of the electric push rod. The outer wall of the I-shaped plate is slidably connected to the outer wall of the support column. Four transmission plates are hinged at the top edge of the I-shaped plate through a torsion spring. The four transmission plates are grouped in two, and the two groups of transmission plates are symmetrically distributed around the axis of the I-shaped plate. The transmission plate is located inside the receiving plate slide groove. A rainproof plate is hinged at the top of the transmission plate through a torsion spring. A number of water diversion channels are arranged on the outer wall of the rainproof plate, and the left and right sides of the rainproof plate use their own center as the hinge point. A hollow plate is fixedly installed between the bottom of the rainproof plate and the top edge of the receiving plate. The inner wall of the transmission plate is fixedly installed There is a fixed plate, and the inclined surface of the fixed plate away from the center of the receiving plate is hinged with a circular plate through a torsion spring. The bottom of the circular plate is hinged with a through plate, and the bottom of the through plate is equidistantly and fixedly installed with a number of deep blocks. The circular holes on the surface of the support column and the receiving plate can be inserted with camouflage objects of similar color to the surrounding environment, such as branches or grass, so as to integrate the video component with the surrounding environment. At the same time, when the video component is adjusted in angle, the rotating component is started, and the output end of the motor inside the rotating component rotates to drive the protective cover to adjust the angle within a certain range, and the protective cover drives the video component to move synchronously; in order to prevent the arrival of freezing rain in winter, the staff uses the wireless module to control the electric push when the video component is installed. The rod sends a signal source to prompt the electric push rod to start. At this time, the stable seat limits the electric push rod, and the telescopic end of the electric push rod pushes the I-shaped plate to move upward along the outer wall of the support column. The I-shaped plate drives the transmission plate to move synchronously inside the receiving plate slide groove. The transmission plate pushes the rain shield to generate an upward movement force. At this time, the rain shield is restricted by the hollow plate, so the hinge shaft between the transmission plate and the rain shield starts to rotate and the transmission plate pulls the rain shield with its own central hinge shaft as the center of the circle. The two sides of the rain shield are expanded upward in an arc-shaped trajectory. At this time, the rain shield shield blocks and protects the video recording component, and the rain shield absorbs the light source emitted by the video recording component. At the same time, the water diversion channel on the inclined surface of the outer wall of the rain shield guides the water flow;When the transmission plate moves in an arc track away from the center of the I-shaped plate, it drives the fixed plate to move synchronously, and the fixed plate drives the circular plate to move synchronously. The circular plate is resisted by the through-plate, causing the hinge shaft between itself and the fixed plate to start rotating. At this time, the circular plate pulls the through-plate to move toward the inner center of the stable seat, and the through-plate drives the deep-drilling block to rub against the ground. The deep-drilling block scrapes through the conical bottom and the inner wall with a smaller angle during the movement and gradually penetrates into the ground. ;

[0007] According to the above technical solution, one end of the penetration plate close to the center of the receiving plate is penetrated by a spring and slidably installed inside the stabilizing seat. The bottoms of several of the penetration blocks are conical, and the angle of the penetration blocks decreases from the edge of the penetration plate to the center. An anti-freezing device is provided under the I-shaped plate to prevent the lubricating oil inside the rotating component from solidifying at low temperatures, making it difficult to adjust the angle of the recording component.

[0008] According to the above technical scheme, the anti-freeze device includes a vertical rod, a heating assembly and a plurality of heat conducting plates, the bottom of the vertical rod is fixedly installed at the top edge of the I-shaped plate, the top of the vertical rod passes through the inside of the receiving plate, the bottom of the heating assembly is fixedly installed on the top of the vertical rod, and the heating assembly is located at the periphery of the rotating assembly. The bottoms of the plurality of heat conducting plates are hinged to the top of the heating assembly through a torsion spring, and the top of the heat conducting plate is in contact with the outer wall of the rotating assembly. In the process of regularly shaking off the debris accumulated on the inclined surface of the outer wall of the rainproof plate to prevent the debris from intercepting rainwater and causing freezing, the telescopic end of the electric push rod drives the I-shaped plate to move reciprocatingly upward and reset, at which time the I-shaped plate drives the vertical rod to move synchronously, the vertical rod drives the heating assembly to move synchronously, the heating assembly drives the heat conducting plate to slide upward and reset along the outer wall of the rotating assembly, and at the same time the heat conducting plate contacts the outer wall of the rotating assembly to generate a resistance force, at which time the heat conducting plate starts to rotate with its own hinge axis as the center, thereby adjusting the sliding angle to avoid sliding obstruction.

[0009] The top of the L-shaped plate is fixedly mounted on the outer wall surface of the vertical rod, the top of the sliding ring is fixedly mounted on the bottom of the L-shaped plate, the outer wall of the telescopic rod is located inside the sliding ring, and the limit plate is fixedly mounted on the outer wall of the electric push rod at one end close to the center of the I-shaped plate, and the top of the ice-breaking cone is fixedly mounted on the bottom of the telescopic end of the telescopic rod. The vertical rod drives the L-shaped plate to move upward and reset, and the L-shaped plate drives the sliding ring to slide upward and reset along the non-self-locking spiral on the outer wall of the fixed end of the telescopic rod, and the built-in clamping block of the sliding ring is in continuous contact with the inner wall of the spiral groove, causing the telescopic rod to generate a rotating force and start to rotate. When the telescopic rod rotates inside the limit plate, it drives the ice-breaking cone to rotate. Before the equipment is debugged, the ice-breaking cone contacts the ground and generates a resistance force. The ice-breaking cone drives the telescopic end of the telescopic rod to shrink toward its own fixed end, and the built-in spring of the telescopic rod buffers the rotation and grinding of the ice-breaking cone.

[0010] According to the above technical solution, the telescopic rod is composed of a fixed end and a telescopic end, a spring is arranged between the fixed end and the telescopic end of the telescopic rod, and a spiral groove is opened on the outer wall of the fixed end of the telescopic rod. The inner part of the limiting plate passes through the outer wall of the fixed end of the telescopic rod, and the outer periphery of the limiting plate is provided with an anti-bacterial device for eliminating bacteria left after animals are attracted to stay after the heating component emits heat to avoid infection of maintenance personnel.

[0011] According to the above technical scheme, the anti-bacterial device includes a U-shaped frame, a transmission rod and a friction plate. The U-shaped frame is fixedly installed on the outer wall of the L-shaped plate at one end close to the center of the stable seat. The top of the transmission rod is hinged to the bottom of the U-shaped frame through a torsion spring. The friction plate is hinged to the outer wall of the stable seat at one end away from the center of the I-shaped plate through a torsion spring. The top of the friction plate is hinged to the bottom of the transmission rod. When the L-shaped plate moves upward and resets, it drives the U-shaped frame to move synchronously. The U-shaped frame pulls the transmission rod to move synchronously. The hinge shaft between the transmission rod and the U-shaped frame starts to rotate, prompting the transmission rod to pull the friction plate to move toward the stable seat. When the U-shaped frame is reset, the friction plate is automatically reset by the torsion spring and drives the transmission rod to reset. This reciprocating process causes the friction plate to reciprocate and rub against the ice surface with cracks formed by the rotation of the ice-breaking cone.

[0012] According to the above technical scheme, the anti-bacterial device also includes a through column and an ultraviolet lamp assembly, wherein the through column penetrates at one end close to the center of the I-shaped plate and is slidably installed inside the slide groove of the stable seat, one end of the outer wall of the through column is hinged to the inclined surface of the inner wall of the friction plate, and the ultraviolet lamp assembly is hinged at the end of the through column close to the center of the I-shaped plate on the side away from the center of the stable seat, and the outer wall of the ultraviolet lamp assembly is in contact with the inner wall of the slide groove of the stable seat. When the friction plate swings, it drives the through column to move back and forth inside the slide groove of the stable seat, and the through column drives the ultraviolet lamp assembly to slide synchronously along the inner wall of the slide groove. When the two ultraviolet lamp assemblies slide close to the center direction of the stable seat at the same time, the resisting spring piece is deformed.

[0013] According to the above technical solution, the anti-bacterial device also includes a spring piece, a cross bar and a refraction plate. The spring piece is fixedly installed on one side of the ultraviolet lamp assembly close to the center of the stable seat, the front and back ends of the cross bar are fixedly installed inside the U-shaped frame, the bottom of the refraction plate is fixedly installed on the top of the spring piece, and the outer wall of the cross bar moves through the inside of the refraction plate. When the spring piece is deformed, the refraction plate is pushed to move horizontally and vertically upward along the outer wall of the cross bar. When the spring piece is reset, the refraction plate is reset synchronously. Therefore, when the ultraviolet lamp assembly slides back and forth to irradiate and disinfect the equipment, the refraction plate expands the coverage of the ultraviolet light through its own mirror.

[0014] The present invention provides a concealed security monitoring camera. It has the following beneficial effects:

[0015] (1) The present invention cooperates with a stabilizing seat, an electric push rod, an I-shaped plate, a transmission plate, a rainproof plate, a hollow plate, a fixed plate, a circular plate, a through plate and a deep-drilling block, so that when the camera assembly is illuminated for supplementary lighting, the light source will not be scattered, further improving the security and concealment of the camera assembly. At the same time, water flows quickly through the water channel on the inclined surface of the outer wall of the rainproof plate and will not accumulate above the camera assembly, thereby preventing the light source from being refracted when water droplets are exposed to sunlight, causing the camera assembly lens to be exposed due to interference from the light source, resulting in blurred recorded images; and the circular plate forms a triangular support with an angle opposite to that of the transmission plate and the deep-drilling block sinks into the ground, thereby improving the stability of the camera assembly for long-term outdoor use and preventing the camera assembly from tilting and collapsing due to strong winds.

[0016] (2) The present invention sets an anti-freezing device, and cooperates with the I-shaped plate, vertical rod, heating component, heat conduction plate, L-shaped plate, sliding ring, telescopic rod, limit plate and ice breaker to enable the heat conduction plate to evenly conduct the heat emitted by the heating component to the inside of the rotating component, so as to prevent the engine oil or lubricating oil in the rotating component from solidifying at low temperature, causing the motor to be unable to rotate or increase the rotation resistance, and prevent the camera component from being unable to adjust the angle or increasing the friction when adjusting the angle, thereby increasing the wear; and the ice breaker is rotated to drill a hole in the frozen ground, and at the same time, the sliding ring is reset to enable the telescopic rod to drive the ice breaker to reverse and twist the hole to cause cracks in the ice surface, and then the frozen surface is broken under the overall gravity pressure of the equipment to ensure that the stable seat and the support column are in contact with the ground, so as to prevent the frozen ground from collapsing easily after thawing, causing the camera image to shake and affect security monitoring.

[0017] (3) The present invention sets an anti-bacteria device, and cooperates with an L-shaped plate, a U-shaped frame, a transmission rod, a friction plate, a through column, an ultraviolet lamp assembly, a spring, a cross bar and a refraction plate, so that the friction plate accelerates the breaking speed of the ice surface and pushes the broken ice to move away from the stable seat, thereby preventing the thawed ice from forming a flow to the bottom of the stable seat, increasing the muddy and soft collapse of the ground, and slowing down the oxidation rate of the bottom of the stable seat; and eliminating bacteria left behind by animals attracted to stay within the equipment due to the heat radiation of the heating component, thereby preventing uninformed maintenance personnel from directly touching the equipment with their bare hands and being infected with bacteria and viruses, providing a safe working environment for the staff and ensuring the health of the staff.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] See also Figure 1-Figure 8One embodiment of the present invention is: a concealed security monitoring camera, including a plurality of support columns 1, the outer walls of the plurality of support columns 1 are provided with a plurality of round holes, a receiving plate 2 is fixedly installed on the top of the support column 1, and a slide groove is provided at the front and back edges of the receiving plate 2, a rotating component 3 is arranged at the center of the top of the receiving plate 2, the rotating component 3 has a built-in motor, a protective cover 31 is arranged at the top of the motor output end, a video recording component 32 is arranged inside the protective cover 31, and the video recording component 32 transmits information through a built-in wireless module, and a stable The top of the stable seat 6 is provided with a slide groove, and the stable seat 6 is located directly below the receiving plate 2. An electric push rod 7 is fixedly installed at the center of the top of the stable seat 6. An I-shaped plate 8 is fixedly installed on the top of the telescopic end of the electric push rod 7. The outer wall of the I-shaped plate 8 is slidably connected to the outer wall of the support column 1. Four transmission plates 9 are hinged at the top edge of the I-shaped plate 8 through a torsion spring. The four transmission plates 9 are grouped in two, and the two groups of transmission plates 9 are symmetrically distributed around the axis of the I-shaped plate 8. The transmission plates 9 are located inside the slide groove of the receiving plate 2. The top of the transmission plates 9 is hinged with a rainproof plate 10 through a torsion spring. The rainproof plate The outer wall of the transmission plate 9 is provided with a plurality of water channels, and the left and right sides of the rainproof plate 10 are hinged at their own centers, a hollow plate 11 is fixedly installed between the bottom of the rainproof plate 10 and the top edge of the receiving plate 2, a fixed plate 12 is fixedly installed on the inner wall of the transmission plate 9, and a beveled surface of the fixed plate 12 away from the center of the receiving plate 2 is hinged with a circular plate 13 through a torsion spring, and a through plate 14 is hinged at the bottom of the circular plate 13, and a plurality of deep blocks 15 are fixedly installed at the bottom of the through plate 14 at equal distances. Through the above cooperation, the light source will not be scattered when the camera assembly 32 is lit to further improve the camera The security and concealment of the recording component 32 is improved, and at the same time, water flows quickly through the water diversion channel on the inclined surface of the outer wall of the rainproof plate 10 without being accumulated above the recording component 32, thereby preventing the water droplets from being refracted by the light source when exposed to sunlight, causing the lens of the recording component 32 to be exposed due to interference from the light source, resulting in blurred recording images; through the above cooperation, the circular plate 13 forms a triangular support with an angle opposite to that of the transmission plate 9, and the deep-drilling block 15 sinks into the ground, thereby improving the stability of the recording component 32 for long-term outdoor use and preventing the recording component 32 from tilting and collapsing due to strong winds.

[0029] The through plate 14 is penetrated by a spring at one end near the center of the receiving plate 2 and is slidably installed inside the stabilizing seat 6. The bottoms of the plurality of penetration blocks 15 are all conical, and the angle of the penetration blocks 15 decreases from the edge of the through plate 14 toward the center. An anti-freezing device 4 is provided below the I-shaped plate 8 to prevent the lubricating oil inside the rotating component 3 from solidifying at low temperatures, making it difficult to adjust the angle of the recording component 32.

[0030] When in use, the circular holes on the surfaces of the support column 1 and the receiving plate 2 can be inserted with camouflage objects of similar color to the surrounding environment, such as branches or grass, so as to integrate the video recording component 32 with the surrounding environment. At the same time, when the video recording component 32 is adjusted in angle, the rotating component 3 is started, and the output end of the motor inside the rotating component 3 rotates to drive the protective cover 31 to adjust the angle within a certain range, and the protective cover 31 drives the video recording component 32 to move synchronously; in order to prevent the coming of freezing rain in winter, when the video recording component 32 is installed, the staff sends a signal source to the electric push rod 7 through the wireless module to prompt the electric push rod 7 to start, and at this time the stabilizing seat 6 drives the electric push rod 7 The electric push rod 7 pushes the I-shaped plate 8 to move upward along the outer wall of the support column 1, and the I-shaped plate 8 drives the transmission plate 9 to move synchronously inside the slide groove of the receiving plate 2. The transmission plate 9 pushes the rainproof plate 10 to generate an upward movement force. At this time, the rainproof plate 10 is restricted by the hollow plate 11. Therefore, the hinge axis between the transmission plate 9 and the rainproof plate 10 begins to rotate and the transmission plate 9 pulls the rainproof plate 10 with its own central hinge axis as the center of the circle. The two sides of the rainproof plate 10 are expanded upward in an arc-shaped trajectory. At this time, the rainproof plate 10 blocks and protects the video recording component 32, and the rainproof plate 10 absorbs the light source emitted by the video recording component 32. The water channel on the outer wall slope of the rainproof plate 10 guides the water flow. Through the above cooperation, the light source will not be scattered when the camera assembly 32 is lit, further improving the security and concealment of the camera assembly 32. At the same time, the water flows quickly through the water channel on the outer wall slope of the rainproof plate 10 and will not accumulate above the camera assembly 32, avoiding the refraction of the light source when the water droplets are exposed to the sun, causing the camera assembly 32 lens to be exposed due to the interference of the light source, resulting in blurred recording images; when the transmission plate 9 moves in an arc trajectory away from the center of the I-shaped plate 8, it drives the fixed plate 12 to move synchronously, and the fixed plate 12 drives the circular plate 13 to move synchronously, and the circular plate 13 moves synchronously. The circular plate 13 is resisted by the through plate 14, causing the hinge axis between itself and the fixed plate 12 to start rotating. At this time, the circular plate 13 pulls the through plate 14 to move toward the inner center direction of the stable seat 6. The through plate 14 drives the penetrating block 15 to rub against the ground. The penetrating block 15 scrapes and gradually penetrates into the ground during the movement through the conical bottom and the inner wall with a smaller angle. Through the above cooperation, the circular plate 13 forms a triangular support with an opposite angle to the transmission plate 9 and the penetrating block 15 sinks into the ground, thereby improving the stability of the recording assembly 32 for long-term outdoor use and preventing the recording assembly 32 from tilting and collapsing due to strong winds.

[0031] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-freezing device 4;

[0032] The anti-freeze device 4 includes a vertical rod 41, a heating component 42 and a plurality of heat conducting plates 43. The bottom of the vertical rod 41 is fixedly installed at the top edge of the I-shaped plate 8, the top of the vertical rod 41 passes through the inside of the receiving plate 2, the bottom of the heating component 42 is fixedly installed on the top of the vertical rod 41, the heating component 42 is located at the periphery of the rotating component 3, and the bottoms of the plurality of heat conducting plates 43 are hinged to the top of the heating component 42 through a torsion spring, and the top of the heat conducting plate 43 contacts the outer wall of the rotating component 3. Through the above cooperation, the heat conducting plate 43 is enabled to evenly conduct the heat emitted by the heating component 42 to the inside of the rotating component 3, so as to avoid the solidification of the engine oil or lubricating oil in the rotating component 3 at low temperature, resulting in the motor being unable to rotate or the rotation resistance being increased, and to prevent the recording component 32 from being unable to adjust the angle or the friction increasing when adjusting the angle, thereby increasing the wear.

[0033] The anti-freeze device 4 also includes an L-shaped plate 44, a sliding ring 45, a telescopic rod 46, a limit plate 47 and an ice-breaking cone 48. The top of the L-shaped plate 44 is fixedly mounted on the outer wall surface of the vertical rod 41, the top of the sliding ring 45 is fixedly mounted on the bottom of the L-shaped plate 44, the outer wall of the telescopic rod 46 is located inside the sliding ring 45, and the limit plate 47 is fixedly mounted on the outer wall of the electric push rod 7 at one end close to the center of the I-shaped plate 8. The top of the ice-breaking cone 48 is fixedly mounted on the bottom of the telescopic end of the telescopic rod 46. Through the above cooperation, the ice-breaking cone 48 is driven to rotate and drill a hole in the frozen ground. At the same time, the sliding ring 45 is reset to cause the telescopic rod 46 to drive the ice-breaking cone 48 to reverse and twist the hole to cause cracks in the ice surface. After that, the frozen surface is broken under the overall gravity pressure of the equipment to ensure that the stable seat 6 and the support column 1 are in contact with the ground, so as to prevent the frozen ground from collapsing easily after thawing, causing the recorded image to shake and affect security monitoring.

[0034] The telescopic rod 46 consists of a fixed end and a telescopic end, a spring is arranged between the fixed end and the telescopic end of the telescopic rod 46, and a spiral groove is opened on the outer wall of the fixed end of the telescopic rod 46. The inner part of the limiting plate 47 passes through the outer wall of the fixed end of the telescopic rod 46, and the outer periphery of the limiting plate 47 is provided with an anti-bacterial device 5 for eliminating bacteria left after the heating component 42 attracts animals to stay there due to the heat dissipation to avoid infection of maintenance personnel.

[0035] When in use, the sundries accumulated on the inclined surface of the outer wall of the rainproof plate 10 are shaken off regularly to prevent the sundries from intercepting rainwater and causing ice. During the process, the telescopic end of the electric push rod 7 drives the I-shaped plate 8 to move reciprocatingly upward and reset. At this time, the I-shaped plate 8 drives the vertical rod 41 to move synchronously, and the vertical rod 41 pushes the heating component 42 to move synchronously. The heating component 42 drives the heat conducting plate 43 to slide upward along the outer wall of the rotating component 3 and reset. At the same time, the heat conducting plate 43 contacts the outer wall of the rotating component 3 to generate a resistance force. At this time, the heat conducting plate 43 starts to rotate with its own hinge axis as the center of the circle, so as to adjust the sliding angle and avoid sliding obstruction. Through the above cooperation, the heat conducting plate 43 is prompted to evenly conduct the heat emitted by the heating component 42 to the inside of the rotating component 3, so as to prevent the internal oil or lubricating oil of the rotating component 3 from solidifying at low temperature, causing the motor to be unable to rotate or the rotation resistance to increase, so as to prevent the recording component 32 from being unable to adjust the angle or the friction force increases when the angle is adjusted, thereby increasing wear; the vertical rod 41 drives the L-shaped plate 44 to move upward and reset The L-shaped plate 44 drives the sliding ring 45 to slide upward and reset along the non-self-locking spiral on the outer wall of the fixed end of the telescopic rod 46, and the built-in block of the sliding ring 45 is in continuous contact with the inner wall of the spiral groove, causing the telescopic rod 46 to generate a rotating force and start to rotate. When the telescopic rod 46 rotates inside the limit plate 47, it drives the ice breaker cone 48 to rotate. Before the equipment is debugged, the ice breaker cone 48 contacts the ground and generates a resistance force. The ice breaker cone 48 pushes the telescopic end of the telescopic rod 46 to retract towards the inside of its own fixed end, and the built-in spring of the telescopic rod 46 buffers the rotation and grinding of the ice breaker cone 48. Through the above cooperation, the ice breaker cone 48 is caused to rotate and drill a hole in the frozen ground. At the same time, the sliding ring 45 is reset, causing the telescopic rod 46 to drive the ice breaker cone 48 to reverse and twist the hole to cause cracks in the ice surface. Afterwards, the frozen surface is broken under the pressure of the overall gravity of the equipment to ensure that the stable seat 6 and the support column 1 are in contact with the ground, so as to prevent the frozen ground from collapsing easily after thawing, causing the recorded image to shake and affect security monitoring.

[0036] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-bacteria device 5;

[0037] The anti-bacteria device 5 includes a U-shaped frame 51, a transmission rod 52 and a friction plate 53. The U-shaped frame 51 is fixedly installed at the outer wall of the L-shaped plate 44 at one end close to the center of the stable seat 6. The top of the transmission rod 52 is hinged to the bottom of the U-shaped frame 51 through a torsion spring. The end of the friction plate 53 away from the center of the I-shaped plate 8 is hinged to the outer wall of the stable seat 6 through a torsion spring. The top of the friction plate 53 is hinged to the bottom of the transmission rod 52. The above cooperation of the friction plate 53 accelerates the crushing speed of the ice surface and pushes the crushed ice to move away from the stable seat 6, preventing the thawed ice from forming water flow to the bottom of the stable seat 6 to increase the muddy and soft collapse of the ground, and slowing down the oxidation speed of the bottom of the stable seat 6.

[0038] The anti-bacterial device 5 also includes a through column 54 and an ultraviolet lamp assembly 55. The through column 54 passes through and is slidably installed in the slide groove of the stable seat 6 at one end close to the center of the I-shaped plate 8. One end of the outer wall of the through column 54 is hinged to the inclined surface of the inner wall of the friction plate 53. The ultraviolet lamp assembly 55 is hinged to the end of the through column 54 close to the center of the I-shaped plate 8 on the side away from the center of the stable seat 6, and the outer wall of the ultraviolet lamp assembly 55 is in contact with the inner wall of the slide groove of the stable seat 6.

[0039] The anti-bacterial device 5 also includes a spring piece 56, a cross bar 57 and a refraction plate 58. The spring piece 56 is fixedly installed on one side of the ultraviolet lamp assembly 55 near the center of the stable seat 6. Both the front and back ends of the cross bar 57 are fixedly installed inside the U-shaped frame 51. The bottom of the refraction plate 58 is fixedly installed on the top of the spring piece 56. The outer wall of the cross bar 57 movably penetrates the inside of the refraction plate 58. Through the above cooperation, the bacteria left after the animals are attracted to stay inside the equipment due to the heat radiation of the heating component 42 are eliminated, and it is prevented that the uninformed maintenance personnel directly touch the equipment with bare hands and are infected with bacteria and viruses, thereby providing a safe working environment for the staff and ensuring the health of the staff.

[0040] When in use, the L-shaped plate 44 moves upward and resets, driving the U-shaped frame 51 to move synchronously, and the U-shaped frame 51 pulls the transmission rod 52 to move synchronously. The hinge shaft between the transmission rod 52 and the U-shaped frame 51 starts to rotate, prompting the transmission rod 52 to pull the friction plate 53 to move in the direction close to the stable seat 6. When the U-shaped frame 51 is reset, the friction plate 53 is automatically reset by the torsion spring and drives the transmission rod 52 to reset. This reciprocating process causes the friction plate 53 to reciprocate and rub against the ice surface with cracks formed by the rotation of the ice-breaking cone 48. Through the above cooperation, the friction plate 53 accelerates the breaking speed of the ice surface and pushes the broken ice to move away from the stable seat 6, preventing the thawed ice from forming a water flow to the bottom of the stable seat 6 to increase the muddy and soft collapse of the ground, and slowing down the oxidation speed of the bottom of the stable seat 6; when the friction plate 53 swings, it drives the through column 54 to slide on the stable seat 6 The through column 54 drives the ultraviolet lamp assembly 55 to slide synchronously along the inner wall of the slide groove when the two ultraviolet lamp assemblies 55 slide close to the center direction of the stable seat 6 at the same time, and the spring piece 56 is deformed. When the spring piece 56 is deformed, the refraction plate 58 is pushed to move horizontally and vertically upward along the outer wall of the cross bar 57. When the spring piece 56 is reset, the refraction plate 58 is reset synchronously. Therefore, when the ultraviolet lamp assembly 55 slides back and forth to irradiate and disinfect the equipment, the refraction plate 58 expands the coverage of the ultraviolet light through its own mirror surface. The above cooperation eliminates the bacteria left after the animals are attracted to stay in the internal range of the equipment due to the heat radiation of the heating assembly 42, and avoids the uninformed maintenance personnel from directly touching the equipment with bare hands and being infected with bacteria and viruses, thereby providing a safe working environment for the staff and ensuring the health of the staff.
