Technical Field
[0001] The utility model relates to the technical field of cameras, in particular to a high temperature resistant and explosion proof camera structure. Background Art
[0002] With the popularization of monitoring technology, monitoring technology is applied in more and more fields. Explosion-proof monitoring cameras belong to explosion-proof monitoring products and are the cross-product of the explosion-proof industry and the monitoring industry. For certain high-risk flammable and explosive environments, the high temperature generated during the use of conventional cameras and the short circuit of the internal circuit may become the ignition source, thereby causing an explosion. Therefore, this type of environment requires a camera that can monitor in a flammable and explosive environment.
[0003] Existing explosion-proof cameras are sealed in the shell and have poor heat dissipation capacity, so they cannot be used in high-temperature environments. Once a short circuit occurs, high temperature and high pressure will be generated, causing the insulating material to decompose and produce gas. Since the sealed gas cannot be discharged, the temperature inside the shell will rise, which is more dangerous. Utility Model Content
[0004] The technical problem to be solved by the utility model is that due to the sealing of the explosion-proof camera, the internal gas cannot be discharged, resulting in the temperature inside the shell rising, which is quite dangerous.
[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a high-temperature resistant and explosion-proof camera structure, including a camera body, the camera body including a shell and a camera head, the shell is provided with an exhaust assembly, the exhaust assembly includes a box body located above the shell, a movable plate located in the box body, a sliding rod passing through the movable plate, a spring connected to the movable plate, and a sealing ball located under the movable plate, an air intake pipe is connected to the bottom of the box body, the air intake pipe is plugged into the shell, and a cooling assembly is provided in the shell.
[0006] As a further solution of the utility model, the sliding rod is located in the box and two of them are symmetrically arranged. The sliding rod is slidably connected to the movable plate. The spring is sleeved on the sliding rod. The two ends of the spring are respectively fixedly connected to the movable plate and the top surface of the box.
[0007] As a further solution of the utility model, exhaust ports are provided on both sides of the box body.
[0008] As a further solution of the utility model, the cooling assembly includes a water inlet pipe, a water outlet pipe, and a U-shaped pipe. Three U-shaped pipes are provided and embedded in the shell. Several connecting pipes are provided between the U-shaped pipes. The water inlet pipe and the water outlet pipe are respectively connected to the two ends of the U-shaped pipe. The other ends of the water inlet pipe and the water outlet pipe extend out of the shell and are fixedly connected to the shell. A water pump is provided on the water inlet pipe.

[0010] As a further solution of the present invention, a buzzer electrically connected to the touch sensor is provided on the housing.
[0011] As a further solution of the utility model, the air intake pipe is sealedly connected to the housing, and an air circuit one-way valve is provided on the air intake pipe.
[0012] The advantage of the utility model over the prior art is that by arranging an exhaust assembly, when the interior of the shell is filled with high-temperature and high-pressure gas, the sealing ball will be pushed to move upward along the intake pipe, squeezing the movable plate and the spring at the same time until the sealing ball is separated from the intake pipe. At this time, the gas enters the box body and is discharged from the exhaust port, avoiding gas retention in the shell and improving safety. After the gas is discharged, the spring drives the sealing ball to reset and reseal. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0022] Combined with Figure 4 , Figure 5 A cooling assembly is provided in the shell 1, and the cooling assembly includes a water inlet pipe 9, a water outlet pipe 10, and a U-shaped pipe 11. Three U-shaped pipes 11 are provided and embedded in the shell 1. Several connecting pipes 12 are provided between the U-shaped pipes. The water inlet pipe 9 and the water outlet pipe 10 are respectively connected to the two ends of the U-shaped pipe 11. The other ends of the water inlet pipe 9 and the water outlet pipe 10 extend out of the shell 1 and are fixedly connected to the shell 1. A water pump is provided on the water inlet pipe 9.
