Description
Technical Field
The utility model relates to a diving equipment field, specifically speaking, the utility model relates to an explosion-proof dive decompression chamber of malleation.
Background
The conventional diving system dives in air with compressed air as a breathing medium, and the decompression chamber is mainly used for fully decompressing in shallow diving operation of 60 meters; the device is used for water outlet and pressure reduction when a fault occurs in the diving operation process; for diver adaptive stress exercises; can be used for treating decompression sickness. The equipment should meet the following requirements of environmental conditions:
the Typha wind level: the working sea state is less than or equal to 5 grade and the storage sea state is less than or equal to 8 grade
Air temperature: -10 to 55 DEG C
Relative humidity: 95% air salt content: 1mg/m3
Tilting and rocking:
the working sea condition is as follows: roll plus or minus 22.5 degrees of transverse inclination plus or minus 15 degrees
Longitudinal shaking plus or minus 10 degrees and longitudinal inclination plus or minus 5 degrees
Explosive gas atmosphere zone 2, hazardous gas in the site: IIA, temperature group T3 (DNV 2.7-2.4.1.2)
The equipment has an explosive gas atmosphere 2 region under the environmental conditions, and dangerous gas exists in the place, so the decompression chamber of the conventional diving system needs to adopt a positive pressure explosion-proof type.
The positive pressure explosion-proof principle: the basic principle of positive pressure explosion prevention is that remote clean air is sent into a room through an air duct by a fan, indoor air is washed and kept at a certain differential pressure, outdoor combustible and dangerous gases are prevented from entering the room, the space in the positive pressure room is guaranteed to be a safe area, non-explosion-proof electricity can be powered in the positive pressure room for use, and the purpose of explosion prevention is achieved.
When the positive pressure explosion-proof and fire gas control system operates, the system automatically triggers alarm, fan stop, output power supply shutoff and non-explosion-proof electrical appliance power supply power loss under the conditions of fire alarm, high concentration alarm of combustible gas or toxic gas, fault alarm of a probe and a sensor, emergency shutoff alarm and system voltage loss overtime.
If the safety electrical equipment (also called weighing equipment) in the positive pressure explosion-proof room needs to be electrified to work before the positive pressure is built in the positive pressure room or after the positive pressure is lost (first-time electric equipment), the equipment must have independent explosion-proof design. For example, explosion-proof type, intrinsic safety type and the like, energy storage electrical equipment with non-explosion-proof design, such as batteries of UPS, interphones and the like, cannot be stored in the positive voltage room. If the electrical equipment is powered by the safety power supply output by the positive pressure explosion-proof control system (the electric equipment is obtained), the electrical equipment (the non-explosion-proof equipment) does not need to be provided with an independent explosion-proof design.
Disclosure of Invention
The utility model aims to solve the technical problem that a malleation explosion-proof dive decompression chamber is provided, changes the continuous circulation under-deck air of decompression chamber, prevents that harmful gas from accumulating the risk that produces the explosion in the decompression chamber.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides an explosion-proof conventional dive decompression chamber of malleation, includes the decompression chamber cabin body, a side of the decompression chamber cabin body sets up the fan pipeline entry, and the opposite side of the decompression chamber cabin body sets up the air outlet, sets up temperature sensing smoke detector, combustible gas probe and toxic gas probe on the decompression chamber cabin body.
Preferably, the audible and visual alarm is arranged on the inner wall of the decompression chamber body.
Adopt the technical scheme of the utility model, can obtain following beneficial effect:
the utility model discloses an explosion-proof dive decompression chamber of malleation carries out air cycle in the cabin is continuous, and the harmful gas in the discharge cabin can prevent like this that the harmful gas accumulation from producing the risk of explosion in the decompression chamber.
Drawings
The contents of the description and the references in the drawings are briefly described as follows:
FIG. 1 is a schematic view of the construction of the present decompression chamber;
the labels in the above figures are: 1. a decompression chamber body; 2. a fan duct inlet; 3. an air outlet; 4. a temperature and smoke sensing probe; 5. a combustible gas probe; 6. a toxic gas probe; 7. an audible and visual alarm.
Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings, in which the shapes, structures, mutual positions and connection relationships of the respective members, the functions of the respective portions, the operation principles, and the like of the respective members are described.
As shown in figure 1, the positive-pressure explosion-proof conventional diving decompression chamber comprises a decompression chamber body 1, wherein a fan pipeline inlet 2 is arranged on one side surface of the decompression chamber body 1, an air outlet 3 is arranged on the other side of the decompression chamber body 1, and a temperature-sensing smoke-sensing probe 4, a combustible gas probe 5, a toxic gas probe 6 and an audible and visual alarm 7 are arranged on the decompression chamber body 1. The air-blower passes through fan pipeline entry 2 and gives the cabin interior blast air, harmful gas in the decompression cabin body 1 or easily fire explosive gas are diluted by concentration under fresh air's dilution, gradually outside 3 discharge cabins by the air outlet, temperature and smog concentration in the storehouse can be surveyed to the temperature sensing smoke probe 4 that the internal setting of decompression cabin, combustible gas probe 5 can survey the under-deck combustible gas concentration, toxic gas probe 6 can survey the interior toxic gas concentration in the storehouse, above-mentioned probe all is through wire and external storehouse outer display, make things convenient for the staff to look over. The audible and visual alarm 7 arranged in the cabin can sense abnormal audible and visual signals in the cabin and send out an alarm for alarming the abnormal audible and visual signals in emergency.
The positive pressure explosion-proof diving decompression chamber continuously performs air circulation in the chamber to discharge harmful gas in the chamber, so that the risk of explosion generated by the accumulation of the harmful gas in the decompression chamber can be prevented. The safety of the decompression chamber body 1 is ensured by the arrangement of various sensors in the decompression chamber.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
