Description
Technical Field
The invention relates to the technical field of power distribution cabinets, in particular to outdoor protection equipment for a power distribution cabinet based on a gas law.
Background
The switch board is distribution system's final stage equipment, we discover in box switch board heat dissipation technical research process, inside the box, the switch board body surface has set up the fin and has promoted the heat-sinking capability, but the heat that the fin gived off piles up inside the box in a large number, only lean on natural heat dissipation hardly immediately to discharge, even set up the fan and take inside steam out, also because the fan takes the convulsions direction of position single out, it is poor to cause the heat extraction effect, inside dead angle is too much can not play radiating effect, in addition switch board in use, often can send the very irritated humming noise of making people and accompany the vibration, this kind of noise not only can influence work and rest in people's daily life, more serious, can cause the resident neurasthenia who lives in near.
In addition, the heat dissipation system in the prior art has poor heat dissipation performance for elements on an internal main board, heat is easily accumulated in the heat dissipation system, short circuit spontaneous combustion of internal components is easily caused due to overhigh internal heat, spontaneous combustion generally occurs under a continuous high-temperature condition, namely when a certain component is always in a high-temperature state, if the component is not subjected to heat dissipation, the situation of spontaneous combustion is likely to occur next, an alarm system is arranged in the prior art to detect the problem of spontaneous combustion, but the alarm can only inform of ignition, and the fire source cannot be blocked at the first time.
The switch board is mostly installed on specific platform in open air mounting means, and the platform is nearer apart from ground, considers the complexity of outdoor weather, and in overcast and rainy weather, when the area water is too much, can make the inside intaking of switch board, leads to the damage of inside components and parts, consequently a switch board outdoor protection equipment based on gas law takes place at the right moment.
Disclosure of Invention
In order to realize the purposes of silencing, automatically alarming when overheating and improving the heat dissipation efficiency when the heat is dissipated, and automatically lifting the cabinet body before the cabinet body is submerged, the invention provides the following technical scheme: the utility model provides an outdoor protection equipment of switch board based on gas law, includes the casing, the bottom fixedly connected with rising mechanism of casing, the inside fixedly connected with support frame of casing, the thermovent has been seted up on the surface of support frame, and the gas vent has been seted up to the bottom of support frame, and there is the acoustical panel in the inside of support frame through moving mechanism swing joint, and the moving mechanism was kept away from to the inside of support frame and lie in the acoustical panel one side fixedly connected with cavity passageway, moving mechanism includes the inflation ball, and one side swing joint that the acoustical panel was kept away from to the inflation ball has the stripper bar, and the one end swing joint that the inflation ball was kept away from to the stripper bar has.
The invention has the beneficial effects that:
1. through installing the support frame at electronic components back, electronic components carries out the during operation and can give off certain heat, and thermovent heat-sinking capability is limited, and the heat just can be piled up in casing inside, according to gas law: the ideal gas state equation pv ═ nRT, where p refers to the pressure of the ideal gas, v is the volume of the ideal gas, n represents the amount of gas species, and T represents the thermodynamic temperature of the ideal gas, and R is the gas constant; from this law, when the volume of gas and the amount of substance are constant values, the pressure of the gas is proportional to the temperature; the pressure inside the shell is increased due to the temperature rise, and the air flow flows to the part with high pressure and the part with low pressure according to the relation between the pressure and the air flow, so that the heat dissipation effect inside the shell is improved.
2. When the electronic element works, micro-vibration is generated, the micro-vibration is a source of noise generated by the power distribution cabinet, the noise has propagation property and is influenced by foreign objects, after the noise collides with the silencing plate, the original first forward-propagated sound wave returns to the original point and is retraced and propagated forwards again, the point is converged with the second forward-propagated sound wave which is not reflected, the two sound waves are equal in amplitude and have a difference of 180 degrees in phase by odd multiples, and therefore the two sound waves interfere with each other and are counteracted, and the silencing effect is achieved;
3. through the aforesaid when the inside accumulational heat of casing is too much and the short time can't reduce, inflation ball thermal expansion extrusion chain, make the rotatory second acoustical panel that promotes of gear, make its and first acoustical panel between the distance enlarge, enlarge the heat dissipation range, if the temperature does not obviously reduce, inflation ball can continue grow and extrude the chain, until with chain extrusion fracture, the chain fracture breaks away from the gear surface, make the second acoustical panel on gear surface drop, the amortization structure of constituteing with first acoustical panel has been destroyed, the noise can not be eliminated, meanwhile, the thermovent is thoroughly opened, the radiating efficiency is improved once more, thereby alarm and radiating effect have been reached.
4. When the pipeline of ventilating has been flooded in surface gathered water and water yield through rising mechanism, pipeline of ventilating is blockked up, makes the inside radiating efficiency of casing slow down, is the novel material of light because of support frame and casing, and inside heat is too much can produce ascending buoyancy, and this buoyancy pulling risees board and spring, makes casing rebound one end distance to the effect that has reached the cabinet body and has risen its automation before being flooded.
Preferably, the surface of the spring of the lifting mechanism is sleeved with a lifting plate, the inner part of the lifting plate and the right side of the spring are provided with vent pipes, and the joint of the spring and the lifting plate is provided with an air hole.
Preferably, the sound-absorbing plate comprises a first sound-absorbing plate, and a second sound-absorbing plate is movably connected to one side, far away from the supporting frame, of the first sound-absorbing plate.
