Description

Technical Field

[0001] This utility model belongs to the technical field of camera protection devices, specifically, it relates to a constant temperature protective cover for anti-fog cameras used in broadcasting ice and snow sports events. Background Technology

[0002] In broadcasting winter sports events, cameras need to operate in harsh environments with low temperatures and high humidity. Therefore, protective covers are usually used to protect the cameras. However, current camera protective covers on the market cannot effectively solve the problem of lens fogging in these environments. Due to the large temperature difference between the inside and outside of the protective cover, moisture easily condenses on the lens surface, severely affecting the clarity and quality of the captured images. Furthermore, ordinary protective covers cannot maintain a constant internal temperature, causing the camera to operate in low-temperature environments for extended periods. This can lead to a decline in the performance of its electronic components, or even malfunctions, affecting the smooth operation of the broadcast.

[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0005] A constant-temperature protective cover for an anti-fog camera used in broadcasting ice and snow sports events includes a front cover, a rear cover, and a camera. The rear cover is connected to the front cover. The camera is installed inside the front and rear covers. A lens mounting hole is provided on one side of the front cover. A sealing ring is provided on the inner wall of the lens mounting hole. The camera lens is installed inside the lens mounting hole. A mounting groove is provided around the inner wall of the front cover, and an electric heating wire is installed in the mounting groove. The electric heating wire is arranged around the camera lens. A humidity sensor is installed inside the front cover and is electrically connected to the electric heating wire. A thermoelectric cooler and a temperature sensor are installed inside the rear cover, and the temperature sensor is electrically connected to the thermoelectric cooler.

[0006] In a preferred embodiment of this utility model, the bottom of the front cover and the rear cover are detachably mounted with a base by screws.

[0007] In a preferred embodiment of this utility model, a U-shaped plate is fixedly provided at the end of the front cover, and a symmetrically arranged limiting groove is provided on the opposite side of the U-shaped plate. A symmetrically arranged limiting plate is fixedly connected to both sides of the rear cover, and the limiting plate is connected to the limiting groove.

[0008] In a preferred embodiment of this utility model, a movable groove is provided on one side of the inner wall of the limiting groove, and a wedge-shaped positioning block is slidably provided on the inner wall of the movable groove. A positioning groove is provided on one side of the limiting plate, and the positioning block is connected to the positioning groove.

[0009] In a preferred embodiment of this utility model, a spring is installed on the inner wall of one side of the movable groove, and one end of the spring is connected to the outer wall of one side of the positioning block.

[0010] In a preferred embodiment of this utility model, the symmetrically arranged movable openings are provided on both sides of the U-shaped plate. The movable openings are connected to the movable grooves. A connecting block is slidably arranged on the inner wall of the movable opening.

[0011] In a preferred embodiment of this utility model, the symmetrically arranged connecting grooves are provided on opposite sides of the U-shaped plate, and symmetrically arranged connecting plates are fixedly connected to both sides of the rear cover, with the connecting plates connected to the connecting grooves.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This invention employs a design where a heating wire surrounds the camera lens. When the camera is working, the heating wire generates heat, raising the temperature around the lens and effectively preventing moisture from condensing into fog on the lens surface. Simultaneously, a humidity sensor is installed inside the protective housing to monitor the internal humidity in real time. When the humidity exceeds a set threshold, the heating wire is automatically activated to ensure that the lens remains clear even in high humidity environments.

[0014] This invention uses a temperature sensor installed inside the protective housing to monitor the temperature around the camera in real time. When the temperature is lower than the lower limit of the set constant temperature range, the semiconductor cooling chip automatically switches to heating mode to provide heat to the camera and maintain a stable internal temperature. When the temperature is higher than the upper limit of the set value, the semiconductor cooling chip switches to cooling mode to reduce the internal temperature of the protective housing. This keeps the internal environment of the protective housing at a constant temperature, ensuring that the camera always works in a suitable temperature environment, thus improving the camera's working stability and reliability.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0025] like Figures 1 to 6 As shown

[0026] A constant-temperature protective cover for an anti-fog camera used in broadcasting ice and snow sports events includes a front cover 1, a rear cover 2, and a camera 3. The rear cover 2 is connected to the front cover 1, and the front cover 1 and rear cover 2 form a single protective cover. The rear cover 2 has ventilation holes and cable inlets / outlets. The ventilation holes ensure airflow inside the protective cover and prevent overheating due to heat accumulation. The cable inlets / outlets use waterproof connectors to ensure a tight connection. A base 8 is detachably mounted on the bottom of the front cover 1 and the rear cover 2 via screws. The camera 3 is mounted inside the front cover 1 and the rear cover 2. A lens mounting hole 7 is provided on one side of the front cover 1, and a sealing ring is provided on the inner wall of the lens mounting hole 7. The camera 3... The lens is installed inside the lens mounting hole 7. During installation, pay attention to the installation position of the sealing ring at the lens mounting hole 7 to ensure a good seal. The inner wall of the front cover 1 has a circumferential mounting groove, and an electric heating wire 9 is installed in the mounting groove. The electric heating wire 9 is arranged around the lens of the camera 3 and is powered by an external power supply. A humidity sensor 10 is installed inside the front cover 1 and is electrically connected to the electric heating wire 9. When the camera 3 is working, the humidity sensor 10 monitors the humidity inside the protective cover in real time. When the humidity sensor 10 detects that the humidity exceeds the set anti-fog threshold, the control system automatically... When the heating wire 9 is activated, it begins to heat up, raising the temperature around the lens of the camera 3. This effectively prevents moisture from condensing on the lens surface, ensuring the camera 3 maintains a clear lens even in high humidity environments. A semiconductor cooling chip 12 and a temperature sensor 11 are installed inside the rear cover 2. The temperature sensor 11 is electrically connected to the semiconductor cooling chip 12. By changing the polarity of the direct current, the cooling or heating function is switched on the same semiconductor cooling chip 12. When the camera 3 is operating, the temperature sensor 11 monitors the temperature inside the protective cover in real time and transmits the detected temperature data to... The control system switches the thermoelectric cooler 12 to heating mode when the temperature is below the lower limit of the constant temperature setting, releasing heat into the protective cover. When the temperature is above the upper limit, the thermoelectric cooler 12 switches to cooling mode to reduce the internal temperature of the protective cover, thereby keeping the internal environment of the protective cover in a constant temperature state, which is beneficial to maintaining the constant temperature of the environment around the camera 3. (The thermoelectric cooler 12 is based on the Peltier effect. When a direct current passes through a thermocouple composed of N-type and P-type semiconductor materials, heat will be transferred from one end to the other end. By reversing the current direction, the functions of the cold end and the hot end can be interchanged, thereby achieving the heating effect.)

[0027] In a specific embodiment, the U-shaped plate 4 has symmetrically arranged connecting grooves 13 on opposite sides. Symmetrically arranged connecting plates 6 are fixedly connected to both sides of the rear cover 2, and the connecting plates 6 are connected to the connecting grooves 13. The front cover 1 has a U-shaped plate 4 fixedly installed at its end. A symmetrically arranged limiting groove 14 is opened on opposite sides of the U-shaped plate 4. Symmetrically arranged limiting plates 5 are fixedly connected to both sides of the rear cover 2, and the limiting plates 5 are connected to the limiting grooves 14. A movable groove 16 is opened on one side of the inner wall of the limiting groove 14. A wedge-shaped positioning block 15 is slidably arranged on the inner wall of the movable groove 16. A positioning groove 17 is opened on one side of the limiting plate 5, and the positioning block 15 is connected to the positioning groove 17. A spring 18 is installed on one side of the inner wall of the movable groove 16, and one end of the spring 18 is connected to the outer wall of one side of the positioning block 15. After the front end of the camera 3 is installed inside the front cover 1, the rear cover 2 is connected to the front cover 1. During the connection process, the limiting plate 5 is inserted into the limiting groove 14, and the connecting plate 6 is inserted into the connecting groove 13. When the limiting plate 5 moves in the limiting groove 14, it squeezes the positioning block 15 into the movable groove 16 until the positioning groove 17 opened on one side of the limiting plate 5 moves to the side of the positioning block 15. At this time, under the action of the spring 18, the positioning block 15 can be pushed into the positioning groove 17 to achieve the limiting effect of the limiting plate 5. After the connection between the rear cover 2 and the front cover 1 is completed, the rear end of the camera 3 is located inside the rear cover 2, so that the front cover 1 and the rear cover 2 form an integral protective cover to achieve the protection of the camera 3. The U-shaped plate 4 has symmetrically arranged movable openings 19 on both sides. The movable openings 19 are connected to the movable groove 16. The inner wall of the movable opening 19 is slidably provided with a connecting block 20. The connecting block 20 is fixedly connected to the side position of the positioning block 15.

[0028] The implementation principle of the constant temperature protective cover for an anti-fog camera used in ice and snow sports broadcasting in this embodiment is as follows:

[0029] In practical use, the front end of the camera 3 is installed inside the front cover 1, so that the lens of the camera 3 is installed in the lens mounting hole 7. During the installation process, pay attention to the installation position of the sealing ring at the lens mounting hole 7 to ensure a good seal. Then, connect the rear cover 2 to the front cover 1. During the connection process, the limiting plate 5 is inserted into the limiting groove 14, and the connecting plate 6 is inserted into the connecting groove 13. When the limiting plate 5 moves in the limiting groove 14, it presses the positioning block 15 into the movable groove 16 until the positioning groove 17 on one side of the limiting plate 5 moves to the side of the positioning block 15. At this time, under the action of the spring 18, the positioning block 15 can be pushed into the positioning groove 17, realizing the limiting effect of the limiting plate 5. After the connection between the rear cover 2 and the front cover 1 is completed, the rear end of the camera 3 is located inside the rear cover 2, realizing the protection of the camera 3. After the rear cover 2 and the front cover 1 are connected together, the base 8 and the camera are connected together. The equipment bracket is fixedly connected to complete the installation of the protective cover. When the camera 3 is working, the humidity sensor 10 monitors the humidity inside the protective cover in real time. When the humidity sensor 10 detects that the humidity exceeds the set anti-fog threshold, the control system automatically starts the heating wire 9. The heating wire 9 starts to heat up, raising the temperature around the lens of the camera 3, effectively preventing water vapor from condensing into fog on the lens surface. At the same time, the temperature sensor 11 monitors the temperature inside the protective cover in real time and transmits the detected temperature data to the control system. When the temperature is lower than the set lower limit of the constant temperature, the semiconductor cooling chip 12 switches to heating mode and releases heat into the protective cover. When the temperature is higher than the upper limit, the semiconductor cooling chip 12 switches to cooling mode and lowers the internal temperature of the protective cover, thereby keeping the internal environment of the protective cover in a constant temperature state, which is beneficial to maintaining a constant temperature around the camera 3.
