Description
Technical field
The utility model relates to a kind of mining from releasing icy cabinet from releasing under the icy cabinet, particularly a kind of coal mine the urgent danger prevention facility.
Background technology
Refuge chamber is when in the down-hole accident taking place, for the hedging personnel provide act of rescue place.Enter the existence cabin of refuge chamber the inside as the personnel of taking refuge after, refuge chamber will be guaranteed to provide comfortable living environment for the personnel of taking refuge, after entering the existence cabin, the personnel of taking refuge close sealed door, personnel concentrate in the less relatively confined space, the existence interior temperature can be constantly soaring, in order to reduce the indoor temperature of existence, generally is to adopt the ice-reserving cabinet in chamber, the ice-reserving cabinet uses blower fan as releasing cold power mostly, and blower fan is divided into pneumatic and electronic.The pneumatic type blower fan need be laid in and compressed-air actuated compressed air bottle is housed in a large number as the power that drives, and a large amount of compressed air bottles can increase dangerous coefficient, increases the cost of chamber self and installing engineering; The electrodynamic type blower fan needs the 24V dc source as power, also need increase simultaneously the amount of battery, normal power supply after the power failure externally, and this kind use electric equipment can reduce safety factor, increases power consumption simultaneously, increases cost; Use pneumatic very big with the electric fan noise.
The utility model content
The purpose of this utility model is to provide under a kind of coal mine the urgent danger prevention facility mining from releasing icy cabinet, solves the ice-reserving cabinet and uses blower fan as releasing the problem that cold power cost is too high, security performance is low, energy consumption is big mostly.
The purpose of this utility model is achieved in that from releasing icy cabinet cabinet, there is the refrigerator lid upper end of cabinet, the side of cabinet release unexpected winner and on pipeline pipe and ShiShimonoseki pipe, in cabinet, be penetrated with the refrigeration air channel, refrigeration air channel inclination arranged crosswise, the two ends in refrigeration air channel are positioned at the cabinet both sides, and the end is for releasing unexpected winner; Being positioned at zone all around, refrigeration air channel in the cabinet is the ice-reserving chamber, and ice-reserving is provided with refrigerator pipes in the chamber, and refrigerator pipes is connected with the refrigeration pipe of outside, and the cabinet wall is provided with insulation layer, and inner refrigerator pipes uses copper pipe to connect.
Beneficial effect owing to adopted such scheme, runs through being provided with the refrigeration air channel in the cabinet, refrigeration air channel inclination arranged crosswise is convenient to evenly release cold in cabinet, and the two ends in refrigeration air channel are positioned at the cabinet both sides, and the end is for releasing unexpected winner; When not using, seal with releasing unexpected winner, being positioned at zone all around, refrigeration air channel in the cabinet is the ice-reserving chamber, and ice-reserving is provided with refrigerator pipes in the chamber, and refrigerator pipes is connected with the refrigeration pipe of outside, thereby cold-producing medium circulates in refrigerator pipes the water in the ice-reserving chamber is become ice, and keeps solid-state always.By the structure in ice-reserving cabinet refrigeration air channel, utilize the interior gas-circulating system of cross-ventilation and chamber to release cold cooling automatically, always have four and release unexpected winner, the oblique angle is corresponding one by one, and the selectable unexpected winner of releasing of opening corresponding angles is released cold.The cold power of releasing of ice-reserving cabinet by the pneumatic or electronic air force that is converted into, is positioned in the refuge chamber, determines usage quantity according to number.Utilize the self-loopa function of air, namely warm air rises, and the principle that cold air descends is carried out self adjusting according to variation of temperature in the chamber, and temperature is more high in the chamber, and the convection velocity of air speeds, and temperature reduces in the chamber, and cross-ventilation speed reduces.Solve the ice-reserving cabinet and used blower fan as releasing the problem that cold power cost is too high, security performance is low, energy consumption is big mostly, reached the purpose of this utility model.
Advantage:
1, cooling-down effect, refuge chamber existence chamber is an independent airtight space taking place after the mine disaster, during owing to blast or other reasons initiation mine disaster, instantaneous temperature can raise rapidly, so the fast-refrigerating of shelter is very crucial.Utilize cross-ventilation to carry out to carry out the automatic adjusting of temperature from releasing coldly from releasing cold ice-reserving cabinet.
2, the take refuge construction cost of facility is low, saves and drops into, and than the pneumatic type power mode, has saved a large amount of air bottles and connector; Compare the electric type power mode, reduced the reserve battery use amount; Reduced first current cost.
3, energy-saving safety.Utilize the interior gas-circulating system of cross-ventilation and chamber to release cold cooling automatically, saved the compressed air consumption of using pneumatic blower fan or the energy consumption of using electric fan, increased safety.
