Description
Technical field
This utility model belongs to field of electrical equipment, relates to a kind of electric meter installation box, especially a kind of new waterproof electric meter installation box body.
Background technology
Electric meter installation box or electric meter installation box body are a kind of power system auxiliary equipments for installing ammeter.Under normal circumstances, electric meter installation box is arranged at open air, and when running into rainy weather, rainwater is easily by penetrating in casing so that the environment in casing becomes moist through, and affects the normal work of ammeter.
Raise additionally, sweltering heat in summer is easily caused case body temperature, there is the possibility burning out ammeter.And, electric meter installation box of the prior art is easily hit by thunder and lightning and damages.In place of this is the deficiencies in the prior art.
Therefore, for defect of the prior art, it is provided that a kind of new waterproof electric meter installation box body of design, to solve above-mentioned technical problem, it is necessary.
Utility model content
The purpose of this utility model is, the defect existed for above-mentioned prior art, it is provided that a kind of new waterproof electric meter installation box body of design, to solve above-mentioned technical problem.
For achieving the above object, this utility model provides techniques below scheme:
A kind of new waterproof electric meter installation box body, described casing is provided with chamber door；It is characterized in that: described chamber door inner peripheries is provided with rubber seal；Being provided with temperature sensor and humidity sensor in described casing, described temperature sensor and humidity sensor are all connected to microcontroller, and the outfan of described microcontroller connects electromagnetic relay；
Drain blower fan it is also equipped with in described casing, described drain blower fan is communicated to the external world by drainage pipe, being disposed with check valve and layer of silica gel along drain wind direction in described drainage pipe, the port, one end that described drainage pipe contacts with the external world is provided with drainage screen；Described drain blower fan is connected to power supply by electromagnetic relay；
Described box bottom is connected with the earth also by earth resistance.
The beneficial effects of the utility model are, by arranging rubber seal at chamber door inner peripheries, it is possible to avoid extraneous rainwater to penetrate in casing；By arranging temperature sensor and humidity sensor in casing, temperature value in vasculum body and humidity value, and the temperature value collected and humidity value are sent to microcontroller, if temperature value or humidity value exceed preset value, microprocessor controls electromagnetic relay turns on, drain blower fan is made to obtain electric work, by the heat in casing or dampness outside drainage pipe is rejected to casing；By arranging check valve in drainage pipe, it is achieved the one-way flow of air-flow in drainage pipe, it is to avoid the air-flow in external environment is in drainage pipe enters casing；By arranging layer of silica gel in drainage pipe, it is possible to fully absorbed by the moisture got rid of to extraneous air-flow through drainage pipe, avoid outside moisture to enter in casing simultaneously；By arranging earth resistance at box bottom, it is possible to avoid the situation that casing is struck by lightning.Additionally, this utility model design principle is reliable, simple in construction, there is application prospect widely.
As can be seen here, this utility model compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent from.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of new waterproof electric meter installation box body that this utility model provides.
Fig. 2 is the control principle drawing of a kind of new waterproof electric meter installation box body that this utility model provides.
Wherein, 1-chamber door, 2-rubber seal, 3-temperature sensor, 4-humidity sensor, 5-microcontroller, 6-electromagnetic relay, 7-drain blower fan, 8-drainage pipe, 9-check valve, 10-layer of silica gel, 11-power supply, 12-earth resistance, 13-drainage screen.
Detailed description of the invention
The utility model is elaborated below in conjunction with the accompanying drawings and by specific embodiment, and following example are to explanation of the present utility model, and this utility model is not limited to implementation below.
As illustrated in fig. 1 and 2, a kind of new waterproof electric meter installation box body that this utility model provides, described casing is provided with chamber door 1；Described chamber door 1 inner peripheries is provided with rubber seal 2；Being provided with temperature sensor 3 and humidity sensor 4 in described casing, described temperature sensor 3 and humidity sensor 4 are all connected to microcontroller 5, and the outfan of described microcontroller 5 connects electromagnetic relay 6；
Drain blower fan 7 it is also equipped with in described casing, described drain blower fan 7 is communicated to the external world by drainage pipe 8, being disposed with check valve 9 and layer of silica gel 10 along drain wind direction in described drainage pipe 8, the port, one end that described drainage pipe 8 contacts with the external world is provided with drainage screen 13；Described drain blower fan 7 is connected to power supply 11 by electromagnetic relay 6；
Described box bottom is connected with the earth also by earth resistance 12.
By arranging rubber seal 2 at chamber door 1 inner peripheries, it is possible to avoid extraneous rainwater to penetrate in casing；By arranging temperature sensor 3 and humidity sensor 4 in casing, temperature value in vasculum body and humidity value, and the temperature value collected and humidity value are sent to microcontroller 5, if temperature value or humidity value exceed preset value, microcontroller 5 controls electromagnetic relay 6 and turns on, make drain blower fan 7 obtain electric work, the heat in casing or dampness are rejected to outside casing through drainage pipe 8；By arranging check valve 9 in drainage pipe 8, it is achieved the one-way flow of air-flow in drainage pipe 8, it is to avoid the air-flow in external environment enters in casing through drainage pipe 8；By arranging layer of silica gel 10 in drainage pipe 8, it is possible to fully absorbed by the moisture got rid of to extraneous air-flow through drainage pipe 8, avoid outside moisture to enter in casing simultaneously；By arranging earth resistance 12 at box bottom, it is possible to avoid the situation that casing is struck by lightning.
Only preferred implementation of the present utility model disclosed above; but this utility model is not limited to this; what any those skilled in the art can think does not has creative change; and the some improvements and modifications made under without departing from this utility model principle premise, all should fall in protection domain of the present utility model.
