Description

Technical Field

[0001] The utility model relates to the technical field of cameras, in particular to a radiation-resistant camera. Background Art

[0002] Radiation-resistant cameras are primarily used for nuclear reconnaissance missions in nuclear-contaminated environments. They can transmit images of contaminated areas to command personnel, enabling them to formulate timely response strategies. Traditional dome cameras are directly exposed to nuclear radiation during nuclear reconnaissance missions. They lack the ability to withstand strong ionizing radiation, making component damage more likely. This leads to short lifespans and high failure rates. Furthermore, existing radiation-resistant cameras lack a rotational field of view, limiting their observation range to a fixed direction, making them inconvenient to use. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a radiation-resistant camera to solve the problems of poor radiation resistance and inconvenience in use in the prior art.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: a radiation-resistant camera, comprising a radiation-resistant lower shell and an upper shell, a camera installed in the lower shell, a radiation-resistant light-transmitting portion provided on the upper shell, and a reflective lens installed in the upper shell, so that light passing through the light-transmitting portion and entering the upper shell can be reflected by the reflective lens and enter the camera.

[0005] As an optimization, a shielding cylinder is vertically arranged in the lower shell, and the camera is installed in the shielding cylinder, wherein the lens of the camera faces upward and the optical axis of the lens is vertically arranged.

[0006] As an optimization, the upper shell is rotatably mounted on the upper end of the lower shell and is driven by a first driving device so that it can rotate around the optical axis of the camera lens.

A second gear meshing with the first gear is mounted on the servo shaft of the first servo. The first servo drives the second gear to rotate, and under the action of the reaction force, the first servo drives the upper shell to rotate.

[0008] As an optimization, the reflective lens is tilted in the length direction so that its front side can reflect the light that passes through the light-transmitting portion and enters the upper shell to the camera, and its two sides in the width direction are rotatably mounted on the inner wall of the upper shell through a rotating shaft.

[0009] As an optimization, a second servo is installed on the back of the reflective lens, and a rotating disk is installed on the servo shaft of the second servo, and an eccentric shaft is installed on the rotating disk, and a sliding block or a rolling block is provided at the end of the eccentric shaft. Correspondingly, a guide groove is opened on the inner wall of the upper shell corresponding to one side of the rotating shaft, and the sliding block or the rolling block slides or rolls in the guide groove. The rotation of the servo shaft of the second servo can make the sliding block or the rolling block move along the guide groove, and the second servo drives the reflective lens to rotate around its rotating shaft through the reaction force.

[0010] As an optimization, the light-transmitting portion includes a light-transmitting hole opened on the side wall of the upper shell, and lead glass is installed in the light-transmitting hole.

[0018] Example: See Figure 1-Figure 2 A radiation-resistant camera includes a radiation-resistant lower shell 1 and an upper shell 2, wherein a camera 3 is installed in the lower shell 1, and a radiation-resistant light-transmitting portion is provided on the upper shell 2, wherein the light-transmitting portion includes a light-transmitting hole opened on the side wall of the upper shell 2, and lead glass 14 is installed in the light-transmitting hole, which has a good radiation shielding ability. A reflective lens 4 is installed in the upper shell 2, and the light that passes through the light-transmitting portion and enters the upper shell 2 can enter the camera 3 after being reflected by the reflective lens 4. Specifically, a shielding tube 5 is vertically arranged in the lower shell 1, and the camera 3 is installed in the shielding tube 5, wherein the lens of the camera 3 faces upward and the optical axis of the lens is arranged vertically, and the shielding tube 5 is made of a lead plate of a certain thickness. Of course, the upper shell 2 and the lower shell 1 can also use radiation-resistant materials such as lead plates.

[0019] In order to adjust the viewing angle of the camera 3, the upper shell 2 is rotatably mounted on the upper end of the lower shell 1 and driven by a first driving device so that it can rotate around the optical axis of the camera 3 lens. Specifically, an annular track is formed at the upper end of the lower shell 1, and a corresponding annular groove is provided at the bottom end of the upper shell 2. The upper shell 2 is buckled on the annular track through the annular groove so that the upper shell 2 can be rotatably mounted on the lower shell 1. A through hole is also provided at the bottom end of the lower shell 1, which is opposite to the lens of the camera 3, so that light can enter the lens of the camera 3 smoothly to complete shooting or recording. Limit blocks can also be provided on the upper shell 2 or the lower shell 1 to limit the rotation angle, so that the maximum angle of one-way horizontal rotation is slightly greater than 360 degrees.

[0020] Specifically, the first drive device includes a first gear 6 fixed to the upper end of the lower housing 1 and coaxial with the optical axis of the camera lens 3, and a first servo 7 fixedly mounted on the inner wall of the upper housing 2. A second gear 8 meshing with the first gear 6 is mounted on the servo shaft of the first servo 7. The first servo 7 drives the second gear 8 to rotate, and under the action of the reaction force, the first servo 7 drives the upper housing 2 to rotate. During use, the servo shaft of the first servo 7 rotates, causing the second gear 8 to rotate. Since the first gear 6 is fixed, the second gear 8 rotates around the first gear 6, thereby driving the entire upper housing 2 to rotate through the first servo 7 to adjust the orientation of the light-transmitting portion and thus change the observation direction.

[0021] In order to adjust the reflection angle of the reflective lens 4 according to actual needs, in this embodiment, the reflective lens 4 is tilted in the length direction so that its front side can reflect the light passing through the light-transmitting portion and entering the upper shell 2 to the camera 3, and its two sides in the width direction are rotatably mounted on the inner wall of the upper shell 2 through the rotating shaft 9. Specifically, the two sides in the horizontal direction of the reflective lens 4 are rotatably mounted on the inner wall of the upper shell 2 through the rotating shaft 9, so that the reflective lens 4 can rotate in the vertical plane. Specifically, a second servo 10 is installed on the back of the reflective lens 4, and a rotating disk 11 is installed on the servo shaft of the second servo 10, and an eccentric shaft 12 is installed on the rotating disk 11. A sliding block or a rolling block is provided at the end of the eccentric shaft 12. Correspondingly, a guide groove 13 is opened on the inner wall of the upper shell 2 corresponding to the rotating shaft 9 on one side. The guide groove 13 has a certain inclination angle, and the sliding block or rolling block slides or rolls in the guide groove 13. The rotation of the servo shaft of the second servo 10 can cause the sliding block or rolling block to move along the guide groove 13, and the second servo 10 drives the reflective lens 4 to rotate around its rotating shaft 9 through the reaction force. During use, the servo shaft of the second servo 10 drives the rotating disk 11 to continuously rotate, causing the eccentric shaft 12 on the rotating disk 11 to rotate. Since the guide groove 13 restricts the sliding block or rolling block on the eccentric shaft 12, the sliding block or rolling block can only move repeatedly along the length direction of the guide groove 13. Therefore, under the action of the reaction force, the second servo 10 drives the reflective lens 4 to rotate around the rotating shaft 9, thereby adjusting the angle of the reflective lens 4.

[0022] Therefore, the utility model

[0023] 1. It has radiation resistance; 2. It can provide a field of view of 360 degrees horizontal rotation and 30 degrees vertical pitch; 3. It has certain waterproof and dustproof capabilities; 4. The internal shielding layer is easy to replace; 5. It can be used indoors and outdoors and can be fixed on a mobile platform.

[0024] In summary, the utility model installs the camera in a radiation-resistant lower shell, so that external light can only enter the camera through the light-transmitting part and the reflective lens, and the external radiation can be shielded by the radiation-resistant upper shell and the light-transmitting part, thereby reducing the radiation entering the camera and improving the camera's radiation resistance.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the present invention that do not depart from the purpose and scope of the technical solution of the present invention should be included in the scope of the claims of the present invention.
