Description

Technical Field

[0001] This utility model relates to the technical field of explosion-proof camera equipment, specifically an explosion-proof camera. Background Technology

[0002] To ensure safe monitoring of flammable and explosive locations, explosion-proof cameras are often required. Utility model patent application CN202122762797.7 discloses an explosion-proof camera. The camera body is used to install and connect components; a mounting slot facilitates the installation and fixation of the camera body; a protective component provides protection for the camera body; a heat dissipation component dissipates heat from the camera body; a wiper is used to clean the camera mounted on the front surface of the camera body; and a control unit controls the connected components. The system controls the windshield wipers to operate on a timer. Explosion-proof cameras offer strong protection and heat dissipation capabilities, maintaining good video quality. However, according to publicly available technical solutions, existing explosion-proof camera equipment has two main drawbacks. First, it cannot effectively monitor the camera's sealing in real time, allowing flammable gases to enter the camera's interior due to poor sealing, thus compromising the explosion-proof effect. Second, it cannot effectively monitor the camera's monitoring mechanism, making it difficult to monitor the camera's sealing performance due to malfunctions in the monitoring mechanism.

[0003] Therefore, how to design explosion-proof cameras has become a problem we need to solve. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an explosion-proof camera to solve the problems mentioned in the background. This utility model is reasonably designed, convenient to use, and suitable for monitoring flammable and explosive places.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof camera, comprising a support plate and an outer cover, wherein a drive assembly is mounted on the support plate, the drive assembly comprising a first motor and a second motor, a camera assembly is mounted on the first motor, the camera assembly comprising a camera and a bracket, a fixing assembly is mounted on the outer cover, the fixing assembly comprising a collar and a retaining ring, a sealing assembly is mounted on the collar, the sealing assembly comprising a first sealing ring and a second sealing ring, an air intake assembly is mounted on the support plate, the air intake assembly comprising an inlet and a connecting pipe, a pressure measuring assembly is mounted on the support plate, the pressure measuring assembly comprising a sleeve and a piston, a detection assembly is mounted on the sleeve, the detection assembly comprising a button and a spring.

[0006] Furthermore, the retaining ring is integrally formed on the top of the outer cover, the first sealing ring is wrapped around the outer side of the retaining ring, the top of the retaining ring is secured with a sealing ring, the top of the sealing ring is secured to the bottom of the support plate by a second sealing ring, the second sealing ring is bonded to the inner wall of the retaining ring and the sealing ring, and the collar is fitted on the outer side of the outer cover, the retaining ring and the sealing ring, the top of the collar is bonded to the bottom of the support plate with sealant.

[0007] Furthermore, the first motor is bolted to the bottom of the support plate, the top of the bracket is keyed to the output shaft of the first motor, the camera is mounted to the bottom of the bracket via a rotating shaft, the second motor is bolted to the outer side of the bracket, one side of the camera is keyed to the output shaft of the second motor, and the outer cover is fitted over the outside of the camera.

[0008] Furthermore, the inlet is welded to the bottom of one side of the support plate, the connecting pipe is opened on the inner side of the support plate, one end of the connecting pipe is equipped with a one-way valve, the other end of the connecting pipe is connected to the inner side of the outer cover, and the inlet is unidirectionally connected to the inner side of the outer cover through the one-way valve and the connecting pipe.

[0009] Furthermore, the sleeve is welded to the bottom of the other side of the support plate, the outer side of the piston is clamped on the inner wall of the sleeve, and the top of the piston is connected to the top of the sleeve by a spring.

[0010] Furthermore, the button is welded to the inner wall of the bottom of the sleeve, the bottom of the sleeve has an opening, and the inner side of the support plate has a thin tube.

[0011] Furthermore, a flexible tube is glued to the bottom of the support plate, a rubber sleeve is glued to the outer side of the collar, and the other end of the flexible tube is glued to the outer side of the rubber sleeve.

[0012] Furthermore, one end of the thin tube is connected to the top of the sleeve, and the other end of the thin tube is connected to the rubber sleeve through a flexible tube.

[0013] Beneficial effects: 1. When in use, motor one drives the camera to rotate horizontally via the bracket, while motor two drives the camera to tilt up and down, allowing for multi-angle monitoring. The top of the outer casing is sealed to the bottom of the sealing ring via a retaining ring, and the top of the sealing ring is sealed to the bottom of the support plate via a second sealing ring, and further sealed and fixed by a collar, ensuring the airtightness of the outer casing. This effectively prevents flammable and explosive gases and dust from entering the inner side of the outer casing, and also effectively prevents electric arcs and localized high temperatures generated during circuit operation from interacting with flammable and explosive materials. When the device comes into contact with explosive gases or dust, inert gas is introduced into the outer casing through the inlet, making the air pressure inside the casing greater than the outside air pressure. This causes the piston to be pushed upward by the inert gas pressure, compressing the spring and separating it from the button. The button is then connected to an alarm located outside the flammable and explosive area via a wire. If a leak occurs in the sealing structure between the top of the outer casing and the support plate, the air pressure inside the casing drops, causing the spring to push the piston to press the button, thus triggering an alarm. This alerts personnel to replenish inert gas into the outer casing and strengthen its sealing, improving the explosion-proof effect of the camera.

[0014] 2. When the explosion-proof camera is in use, if the piston wears down due to prolonged fixation, the inert gas inside the outer casing will flow through the gap between the piston and the sleeve to the top of the sleeve, then through a thin tube into a flexible hose, and finally into the inside of the rubber sleeve. This will cause the rubber sleeve to expand. Personnel can observe the size of the rubber sleeve to determine whether the sleeve and piston are maintaining a sealed state, so that maintenance work can be carried out in a timely manner. This effectively ensures the reliability of the air pressure monitoring work inside the outer casing and reduces false alarms.

[0015] 3. This explosion-proof camera is reasonably designed, highly efficient and convenient to use, and suitable for monitoring flammable and explosive environments. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: an explosion-proof camera, including a support plate 1 and an outer cover 2. A driving assembly is mounted on the support plate 1, the driving assembly including a first motor 10 and a second motor 11. A camera assembly is mounted on the first motor 10, the camera assembly including a camera 8 and a bracket 9. A fixing assembly is mounted on the outer cover 2, the fixing assembly including a collar 3 and a retaining ring 5. A sealing assembly is mounted on the collar 3, the sealing assembly including a first sealing ring 6 and a second sealing ring 7. The support plate 1 is equipped with... The system is equipped with an air intake assembly, which includes an inlet 12 and a connecting pipe 13. A pressure testing assembly, comprising a sleeve 15 and a piston 16, is mounted on the support plate 1. A detection assembly, including a button 18 and a spring 17, is mounted on the sleeve 15. A retaining ring 5 is integrally formed on the top of the outer cover 2. A first sealing ring 6 wraps around the outer side of the retaining ring 5. A sealing ring 4 is secured to the top of the retaining ring 5. The top of the sealing ring 4 is secured to the bottom of the support plate 1 by a second sealing ring 7. The second sealing ring 7 is bonded... On the inner walls of the retaining ring 5 and the sealing ring 4, the collar 3 is fitted around the outer side of the outer cover 2, the retaining ring 5, and the sealing ring 4. The top of the collar 3 is glued to the bottom of the support plate 1 with sealant. A flexible tube 21 is glued to the bottom of the support plate 1. A rubber sleeve 20 is glued to the outer side of the collar 3. The other end of the flexible tube 21 is glued to the outer side of the rubber sleeve 20. One end of the thin tube 19 is connected to the top of the sleeve 15, and the other end of the thin tube 19 is connected to the rubber sleeve 20 through the flexible tube 21. When the piston 16 is long... When wear occurs due to the fixed connection between the piston 16 and the sleeve 15, the inert gas inside the outer casing 2 flows through the gap between the piston 16 and the sleeve 15 to the top of the sleeve 15, then through the thin tube 19 into the hose 21, and then into the inside of the rubber sleeve 20, causing the rubber sleeve 20 to expand. Personnel can observe the size of the rubber sleeve 20 to determine whether the sleeve 15 and the piston 16 are in a sealed state, so that maintenance work can be carried out in a timely manner, thereby effectively ensuring the reliability of the air pressure monitoring work inside the outer casing 2 and reducing false alarms.

[0023] In this embodiment, the first motor 10 is bolted to the bottom of the support plate 1, the top of the bracket 9 is keyed to the output shaft of the first motor 10, the camera 8 is mounted to the bottom of the bracket 9 via a rotating shaft, the second motor 11 is bolted to the outer side of the bracket 9, one side of the camera 8 is keyed to the output shaft of the second motor 11, the outer cover 2 is located on the outside of the camera 8, the inlet 12 is welded to the bottom of one side of the support plate 1, the connecting pipe 13 is opened on the inner side of the support plate 1, one end of the connecting pipe 13 is equipped with a one-way valve 14, and the other end of the connecting pipe 13... One end is connected to the inside of the outer casing 2. The inlet 12 is connected to the inside of the outer casing 2 in one direction through a one-way valve 14 and a connecting pipe 13. The sleeve 15 is welded to the bottom of the other side of the support plate 1. The outer side of the piston 16 is stuck on the inner wall of the sleeve 15. The top of the piston 16 is connected to the top of the sleeve 15 through a spring 17. The button 18 is welded to the inner wall of the bottom of the sleeve 15. The bottom of the sleeve 15 has an opening. The inner side of the support plate 1 has a thin tube 19. In use, the motor 10 drives the camera 8 to rotate horizontally through the bracket 9. The second 11 rotates the camera 8 up and down, allowing it to monitor from multiple angles. The top of the outer casing 2 is sealed to the bottom of the sealing ring 4 by the sealing ring 6 on the retaining ring 5. The top of the sealing ring 4 is sealed to the bottom of the support plate 1 by the sealing ring 7, and then sealed and fixed by the collar 3, ensuring the airtightness of the outer casing 2. This effectively prevents flammable and explosive gases and dust from entering the inner side of the outer casing 2, and also effectively prevents the electric arc and local high temperature generated by the circuit from coming into contact with flammable and explosive gases and dust. Inlet 12 allows air to flow into the outer casing 2. Inert gas is used to make the air pressure inside the outer casing 2 greater than the outside air pressure. This causes the piston 16 to be pushed upward by the inert gas pressure. The piston 16 compresses the spring 17 and separates it from the button 18. The button 18 is then connected to an alarm located outside a flammable and explosive area via a wire. If a leak occurs in the sealing structure between the top of the outer casing 2 and the support plate 1, the air pressure inside the outer casing 2 will drop. The spring 17 will push the piston 16 to squeeze the button 18, thereby triggering an alarm. This alerts personnel to replenish the inert gas inside the outer casing 2 in time and strengthen the sealing of the outer casing 2, thereby improving the explosion-proof effect of the camera 8.

[0024] This explosion-proof camera provides power to all electrical equipment via an external power supply. During operation, motor 10 drives camera 8 to rotate horizontally via bracket 9, while motor 2 drives camera 8 to rotate vertically, allowing for multi-angle monitoring. The top of the outer casing 2 is sealed to the bottom of sealing ring 4 via sealing ring 1 6 on retaining ring 5. The top of sealing ring 4 is sealed to the bottom of support plate 1 via sealing ring 2 7, and further sealed and fixed by collar 3, ensuring the airtightness of the outer casing 2. This effectively prevents flammable and explosive gases and dust from entering the inner side of the outer casing 2, and also effectively prevents the electric arc and localized high temperatures generated during circuit operation from contacting flammable and explosive gases and dust. Inert gas is introduced into the outer casing 2 through inlet 12, making the pressure inside the outer casing 2 greater than the external pressure. This causes piston 16 to be pushed upwards by the inert gas pressure, compressing spring 17 and separating it from button 18. Button 18 is connected to an alarm located outside of flammable and explosive areas via a wire. If a leak occurs in the sealing structure between the top of the outer casing 2 and the support plate 1, the air pressure inside the outer casing 2 drops. Spring 17 pushes piston 16 to press button 18, thereby triggering an alarm. This prompts personnel to replenish inert gas into the outer casing 2 and strengthen its sealing, improving the explosion-proof effect of camera 8. When piston 16 wears due to prolonged fixation, the inert gas inside the outer casing 2 flows through the gap between piston 16 and sleeve 15 to the top of sleeve 15, then through thin tube 19 into hose 21, and then into the inside of rubber sleeve 20, causing rubber sleeve 20 to expand. Personnel can observe the size of rubber sleeve 20 to determine whether sleeve 15 and piston 16 are in a sealed state, enabling timely maintenance and effectively ensuring the reliability of air pressure monitoring inside the outer casing 2, reducing false alarms.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
