Description

Technical Field

[0001] The utility model belongs to the field of explosion-proof camera, in particular to a mobile explosion-proof camera device with both intercom and fill-in light functions. Background Art

[0002] When conducting special operations such as inspection and maintenance in confined spaces in industries such as petroleum, chemical, smelting, and municipal administration, such as furnaces, tower kettles, tanks, warehouses, pools, tank trucks, pipelines, flues, etc., casualties often occur due to the closed and complex working environment. For example, poisoning caused by the leakage of toxic and harmful gases, spontaneous coma, and injuries caused by improper operation. Since most confined spaces are explosive environments, the equipment used is required to be explosion-proof. There are generally three existing solutions.

[0003] First, supervisors check the confined space entrance at different times or enter the confined space to check. A more primitive method is to confirm the safety of the operation by knocking on the pipe wall and shouting.

[0004] Second, a camera is installed in the confined space and connected to a host outside the confined space through wired or wireless means. Supervisors observe the operation process in the confined space through the screen of the host. Since confined spaces are closed environments, the light is dim, which makes the video surveillance image relatively blurry, making it difficult to detect danger in time.

[0005] Third, the safety of operations inside confined spaces is confirmed through walkie-talkies, but confined spaces are generally made of metal, which interferes with the transmission efficiency of the walkie-talkies and causes danger due to untimely information transmission.

[0006] In summary, no matter which of the above methods is adopted, there are potential dangers, so a device that can overcome the above shortcomings is particularly important. The present invention provides a mobile explosion-proof camera device with both intercom and fill light functions to make up for the above shortcomings. Summary of the invention

[0035] Referring to the accompanying drawings, this embodiment is described, a mobile explosion-proof camera device with both intercom and fill light functions, comprising:

[0036] The joint screw assembly 2 is sealed and connected to the explosion-proof flashlight assembly 1 at one end, and sealed and connected to the explosion-proof camera and speaker assembly 3 at the other end. The explosion-proof flashlight assembly 1 is provided with a light wick 1-12 and a reed switch 1-13, and the connection or disconnection of the light wick 1-12 power supply circuit is controlled by the reed switch 1-13; the reed switch 1-13 is also called a magnetic reed switch, and the magnetic control principle of the reed switch 1-13 is based on the characteristics of magnetic materials and electromagnetic induction. The core component of the reed switch is two or more magnetic reeds, which are usually made of soft magnetic materials. These reeds are encapsulated in a glass tube filled with inert gas or vacuum. One end of each reed is in contact to form a closed circuit, while the other end remains separated.

[0038] The cable introduction component 5 has an opening at one end which is sealed and connected to the explosion-proof camera and speaker component 3, and a rubber plug 5-3 is set in the opening at the other end. The rubber plug 5-3 is used to introduce the cable into the explosion-proof camera and speaker component 3 and keep the explosion-proof camera and speaker component 3 sealed; through the setting of the rubber plug 5-3, it can be ensured that the cable can enter the device for normal power supply while ensuring the sealing of the cable when it is introduced. The power supply end of the cable can use a mobile power supply or a fixed power supply point for power supply, which can be selected according to actual needs. The rubber plug 5-3 is installed in the introduction sleeve 5-4 through a flat washer 5-2. In the mode in which the device can be moved, the explosion-proof flashlight component 1 is set to be directly above the explosion-proof camera and speaker component 3, and the device can be moved by means of the explosion-proof flashlight component 1. The appearance design of the explosion-proof flashlight component 1 should be conducive to grasping and moving, so that the setting of a separate handle can be omitted, the complexity of the device can be reduced, and the convenience of movement can be improved.

[0039] The bracket assembly 6 has one end connected to the explosion-proof camera and speaker assembly 3 to support the speaker assembly 3 at different angles. The bracket assembly 6 is provided to facilitate the support of the explosion-proof camera and speaker assembly 3 at different angles when used in a fixed mode, so as to adjust according to the user's habits.
