Under the influence of gamma ray radiation, various electronic components of ordinary cameras will be quickly damaged and cannot be used for a long time.

[0020] In order to better understand the above-mentioned technical scheme, the technical scheme of the embodiments of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0021] The first embodiment of the present application provides a radiation-proof camera core 10, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the radiation-proof camera movement 10 includes: a shielding component 100 and a sensor 200. The shielding component 100 includes: a first shell 110, a driving module 120 and a baffle 130. A mounting cavity 111 is formed in the first shell 110. A light-transmitting port 112 is provided on the wall of the first shell 110. The driving module 120 is connected to the first shell 110. The baffle 130 is connected to the driving module 120. The driving module 120 is used to drive the baffle 130 to move. The sensor 200 is arranged in the mounting cavity 111. The sensor 200 is arranged opposite to the light-transmitting port 112. When the sensor 200 is in a non-working state, the baffle 130 blocks the light-transmitting port 112. When the sensor 200 is in a working state, the baffle 130 avoids the light-transmitting port 112.

[0022] In this embodiment, the first housing 110 and the baffle 130 are made of shielding material, and the shielding material can be lead metal by way of example. The first housing 110 provides shielding protection for the sensor 200, and the sensor 200 is disposed in the mounting cavity 111 of the first housing 110 and opposite to the light-transmitting opening 112 of the first housing 110. The driving module 120 is disposed on the first housing 110, and can drive the baffle 130 to move, thereby controlling the baffle 130 to block or avoid the light-transmitting opening 112.

[0023] like Figure 1 and Figure 4 As shown, when the camera is not in use, the sensor 200 is not in operation, and the driving module 120 drives the baffle 130 to block the light-transmitting opening 112, so that the light-transmitting opening 112 is in a closed state to shield radiation and weaken the gamma ray radiation received by the sensor 200. Figure 2 and Figure 3 As shown, when the camera is running, the sensor 200 is in working state, and the driving module 120 drives the baffle 130 to avoid the light-transmitting port 112, so that the light-transmitting port 112 is in an open state, and light can pass through the light-transmitting port 112 to illuminate the sensor 200 for imaging, thereby ensuring the normal operation of the camera function.

[0024] By controlling the movement of the baffle 130 through the driving module 120, the sensor 200 can be shielded and protected in a non-operating state, thereby reducing the radiation received by the sensor 200, increasing the service life of the sensor 200, and further increasing the service life of the radiation-proof camera. In addition, the shielding assembly 100 has a simple structure and a small volume, which reduces the space occupied by the radiation-proof camera core 10.

[0025] In some embodiments provided in this application, Figure 5 and Figure 6 As shown, optionally, the driving module 120 includes: a mounting frame 121, at least two electromagnets 122 and a slider 123, the mounting frame 121 is connected to the first shell 110, the baffle 130 is movably connected to the mounting frame 121, the two electromagnets 122 are respectively located at two ends of the mounting frame 121, the slider 123 is located between the two electromagnets 122, the slider 123 is slidably connected to the mounting frame 121, the magnetic force generated by the electromagnet 122 can drive the slider 123 to move, and the slider 123 is used to drive the baffle 130 to move.

[0026] In this embodiment, the mounting frame 121 is located on a side of the first housing 110 where the light-transmitting opening 112 is provided. Two electromagnets 122 are connected to the two ends of the mounting frame 121 respectively. Any electromagnet 122 can generate magnetic force when powered on. The slider 123 is made of metal material. The magnetic force can drive the middle slider 123 to slide along the mounting frame 121 in a direction close to the electromagnet 122. By controlling the power-on state of the electromagnets 122 at both ends, the direction of the magnetic force can be controlled, and then the movement direction of the slider 123 can be controlled, so that the slider 123 can drive the baffle 130 to follow the slider 123 during the sliding process, so that one end of the baffle 130 moves relative to the mounting frame 121, and the other end blocks or avoids the light-transmitting opening 112.

[0027] In a possible embodiment, the electromagnet 122 on one side generates magnetic force after being energized, so as to attract the slider 123 to move closer to the electromagnet 122 on the energized side.

[0028] In another possible embodiment, opposite magnetic poles are provided at both ends of the slider 123, and the electromagnets 122 at both ends are energized at the same time to generate magnetic poles in the same direction, which generate attraction on the corresponding magnetic poles of the slider 123. By switching the direction of the current flowing in the electromagnet 122, the magnetic poles of the electromagnet 122 are controlled, and then the magnetic driving direction of the electromagnet 122 on the slider 123 is controlled.

[0029] In some embodiments provided in this application, Figure 6 As shown, optionally, the driving module 120 further includes: a rack 124 and a gear 125 , the rack 124 is connected to the slider 123 , the gear 125 is connected to the end of the baffle 130 , and the gear 125 is meshedly connected to the rack 124 .

[0030] In this embodiment, the gear 125 is meshed with the rack 124 for transmission, and the baffle 130 is rotatably connected to the mounting frame 121. When the slider 123 slides, the rack 124 follows the slider 123 to move in a straight line, and drives the gear 125 located at the end of the baffle 130 to rotate, so that one end of the baffle 130 follows the gear 125 to rotate, and the other end blocks or avoids the light-transmitting opening 112, so that the slider 123 drives the baffle 130 to rotate through the rack 124 and the gear 125.

[0031] In some embodiments provided in the present application, optionally, the blocking piece 130 is slidably connected to the mounting frame 121 , and the slider 123 is connected to the end of the blocking piece 130 .

[0032] In this embodiment, the baffle 130 is slidably connected to the mounting frame 121, and the slider 123 is connected to the end of the baffle 130. When the slider 123 slides, one end of the baffle 130 follows the slider 123 to slide, and the other end blocks or avoids the light-transmitting opening 112, so that the slider 123 drives the baffle 130 to slide.

[0033] In some embodiments provided in this application, Figure 5 and Figure 6 As shown, optionally, the blocking piece 130 includes: a pull rod 131 and a shielding body 132 , one end of the pull rod 131 is movably connected to the mounting frame 121 and connected to the slider 123 , and the shielding body 132 is connected to the other end of the pull rod 131 .

[0034] In this embodiment, the two ends of the tie rod 131 are respectively connected to the mounting frame 121 and the shielding body 132, so that when the slider 123 drives one end of the tie rod 131 to move, the other end of the tie rod 131 can drive the shielding body 132 to move, so that the shielding body 132 can block or avoid the light-transmitting opening 112. In the radial direction of the tie rod 131, the diameter of the tie rod 131 is smaller than the outer dimensions of the shielding body 132, which reduces the size and weight of the baffle 130, improves the flexibility of the movement of the baffle 130, realizes the lightweight of the shielding assembly 100, saves shielding materials, and reduces the cost of the baffle 130.

[0035] Exemplarily, the shielding body 132 may be cylindrical, the light transmission opening 112 may be circular, and the cross-sectional size of the shielding body 132 matches the size of the light transmission opening 112 , so that the diameter of the shielding body 132 is slightly larger than the diameter of the light transmission opening.

[0036] In some embodiments provided in this application, Figure 3 and Figure 4 As shown, optionally, an avoidance groove 113 is provided on the first shell 110 , and the blocking piece 130 can move in the avoidance groove 113 .

[0037] In this embodiment, the blocking piece 130 is located in the avoidance groove 113 of the first shell 110, which reduces the thickness of the shielding assembly 100, and the side wall of the avoidance groove 113 can limit the blocking piece 130, and the movement range of the blocking piece 130 can be limited by the avoidance groove 113.

[0038] In some embodiments provided in this application, Figure 3 and Figure 4 As shown, optionally, the blocking piece 130 is rotatably connected to the first shell 110 , and a curved surface 114 is provided on the side wall of the avoidance groove 113 , and the blocking piece 130 can rotate along the curved surface 114 .

[0039] In this embodiment, the slider 123 can drive the baffle 130 to rotate, and the end of the baffle 130 rotates along the arc-shaped side wall of the avoidance groove 113, so that the avoidance groove 113 is adapted to the movement path of the baffle 130, thereby preventing the avoidance groove 113 from hindering the rotation of the baffle 130. The baffle 130 can swing in the avoidance groove 113, thereby improving the smoothness of the rotation of the baffle 130.

[0040] In some embodiments provided in this application, Figure 1 and Figure 2 As shown, optionally, the radiation-proof camera movement 10 also includes: a second shell 300 and a lens module 400, the second shell 300 is connected to the first shell 110, a accommodating cavity 310 is formed in the second shell 300, the lens module 400 is arranged in the accommodating cavity 310, and the lens module 400 is arranged opposite to the light-transmitting port 112.

[0041] In this embodiment, the second housing 300 is made of shielding material, and the second housing 300 is connected to the first housing 110 and the lens module 400 respectively by screws. The second housing 300 is located at one end of the first housing 110 provided with a light-transmitting port 112, and the lens module 400 is located in the accommodating cavity 310 of the second housing 300 and is arranged opposite to the light-transmitting port 112. The second housing 300 provides protection for the lens module 400. Specifically, the lens module 400 includes: optical glass, a module bracket and a motor. After the light passes through the optical glass of the lens module 400, it can enter the first housing 110 through the light-transmitting port 112, thereby focusing the light on the sensor 200, and the sensor 200 receives the light for imaging.

[0042] In some embodiments provided in this application, Figure 1 and Figure 2 As shown, optionally, the radiation proof camera movement 10 further includes: a third shell 500 and a circuit board 600, the third shell 500 is connected to the first shell 110, a shielding cavity 510 is formed in the third shell 500, the circuit board 600 is arranged in the shielding cavity 510, and the circuit board 600 is electrically connected to the lens module 400, the sensor 200 and the driving module 120.

[0043] In this embodiment, the third housing 500 is made of shielding material. The third housing 500 is connected to the first housing 110 and the lens module 400 respectively by screws. The first housing 110 is located between the third housing 500 and the second housing 300. The third housing 500 wraps the circuit board 600 in the shielding cavity 510, and the circuit board 600 is connected to the lens module 400, the sensor 200 and the driving module 120 by cables to realize the control and communication connection of related electronic components. The third housing 500 provides shielding protection for the circuit board 600 to prevent the circuit board 600 from being affected by radiation. The third housing 500, the first housing 110 and the baffle 130 together enclose a closed shielding space to shield the components inside the space.

[0044] A second embodiment of the present application provides a radiation-proof camera, which includes the radiation-proof camera movement 10 provided by any one of the first embodiments described above.

[0045] In this embodiment, it should be noted that the radiation-proof camera includes the radiation-proof camera movement 10 provided by any of the above embodiments, and thus has all the beneficial technical effects of the above radiation-proof camera movement 10, which will not be described here to avoid repetition.

[0046] In a specific embodiment, a radiation-proof camera core module radiation-proof reinforcement device (i.e., radiation-proof camera core 10) is provided. The radiation-proof camera core 10 mainly includes a PCB (Printed Circuit Board) control board, a sensor board, a first housing 110, a second housing 300, a third housing 500, a lens module 400, an electromagnetic shielding controller, etc. The PCB control board is wrapped in a separate space by the third housing 500.

[0047] The sensor board is fixed on the first shell 110, and then the electromagnetic drive controller is fixed on the first shell 110 by screws, wherein the electromagnetic shielding drive controller is mainly composed of a drive module 120 and a shielding baffle 130. A feature similar to a runway circle is designed on the first shell 110, and the shielding baffle 130 can swing in the runway circle.

[0048] The present invention designs an electromagnetic shielding drive controller device on the first shell 110, and optimizes the design without affecting the overall size of the movement. The electromagnetic shielding controller can protect the sensor board and other components when the camera is not in use. The direction of the output force is controlled by converting the positive and negative poles of the current in the drive module 120, that is, the shielding baffle 130 can move along a trajectory within a certain range through the drive module 120. When the camera is running, the drive module 120 is controlled to rotate the shielding baffle 130 to the uppermost side and is in the open state. At this time, light can enter the sensor through the lens to form an image. During the entire process of the camera being turned on, the shielding baffle 130 is in the open state to ensure the normal operation of the camera function.

[0049] When the camera is in the installation process, the camera function is not needed, the control current is reversed, and the shielding baffle 130 is rotated to the bottom by the force in the opposite direction. The light-transmitting port 112 is closed to block the light from entering, that is, the closed state. The shielding baffle 130 can not only block the light from entering, but also attenuate the radiation of gamma rays, fully protecting the components from use in a non-working state. At this time, the sensor board and other components are protected in the closed cavity formed by the third shell 500, the first shell 110, and the shielding baffle 130, which greatly reduces the radiation damage of gamma rays to the sensor board and its components.

[0050] This solution uses the motion control of the electromagnetic shield to shield and protect the sensor board, electronic circuit board and other components when the camera is not in operation, thereby increasing the effective service life of the camera. The anti-radiation reinforcement device for the core module has a small structure and does not affect the size of the original core. The anti-radiation reinforcement device for the core module can be operated through the camera power switch, which is simple and easy.
