Technical Field

The invention relates to the technical field of valve explosion-proof motors, in particular to an explosion-proof energy-saving direct current motor.

Background

The motor is commonly called as a motor, and is an electromagnetic device for realizing electric energy conversion or transmission according to the law of electromagnetic induction, the motor is represented by a letter M in a circuit, the motor mainly has the function of generating driving torque and is used as a power source of electrical appliances or various machines, the motor types are divided according to the types of working power supplies and can be divided into a direct current motor and an alternating current motor, and the direct current motor has the advantages of good speed regulation performance, easiness in starting, capability of carrying and starting and the like, and is widely applied.

When the existing direct current motor, particularly a small direct current motor, is used, the phenomena of heating and scalding can occur after the existing direct current motor, particularly a small direct current motor, is used for a long time due to the fact that a heat dissipation structure is not available generally, and the existing direct current motor is cooled through an external fan so as to be explosion-proof.

Disclosure of Invention

The invention aims to solve the problems that a direct current motor in the prior art is poor in heat dissipation effect and does not have an explosion-proof function, and provides an explosion-proof energy-saving direct current motor.

In order to achieve the purpose, the invention adopts the following technical scheme: an explosion-proof energy-saving direct current motor comprises a shell and an output shaft, wherein a containing groove is formed in one side, connected with the output shaft, of the shell and is fixedly connected with an output element;

the accommodating groove is positioned at the bottom of the output element and is fixedly connected with a first resistance layer, the bottom of the accommodating groove is fixedly connected with a second resistance layer, a conductor sliding block is connected in a sealing and sliding manner in the space between the first resistance layer and the second resistance layer, one side of the conductor sliding block is fixedly connected with a spring capable of conducting electricity, the fixed end of the spring is fixedly connected with the side wall of the accommodating groove, and one end of the air hole, which is far away from the liquid cavity, is communicated with the space between the first resistance layer and the second resistance layer;

one end of the spring, which is far away from the conductor sliding block, is electrically connected with a rotating plate positioned in the liquid cavity through a lead, the side wall of the liquid cavity is fixedly connected with a conductor layer, and the conductor layer is electrically connected with a dry battery.

In the above explosion-proof energy-saving direct current motor, the liquid chamber is of a ring column structure, the upper side and the lower side of the liquid chamber are hermetically connected with two air holes through breathable films, the breathable films are made of intelligent high polymer gel materials, the first resistance layer is electrically connected with the output element, the conductor slide block is electrically connected with the dry battery, and the liquid chamber is filled with ionic liquid.

Compared with the prior art, the invention has the advantages that:

1. according to the invention, the liquid cavity is arranged in the shell and filled with liquid, so that the absorption of heat emitted by the output element during working is realized, wherein the liquid is ionic liquid and has the advantages of non-volatility, high heat resistance and non-flammability, so that a larger air pressure cannot be generated due to volatilization in the heat exchange process, and the two ends of the liquid cavity are provided with the breathable films which can convey gas to enter and exit, so that the heat exchange between the liquid in the liquid cavity and the outside is improved, and the heat absorption capacity generated by the direct current motor is increased;

2. in the invention, the direct current motor is powered by a battery and is connected with the two resistance layers through the conductor sliding block, when the direct current motor is in a normal state, the first resistance layer connected with the output element is completely connected, and at the moment, two ends of the dry point battery are equivalent to two ends of the output element which are directly connected, so that the output rotation with the maximized power is realized;

3. meanwhile, the temperature in the ionic liquid is low, so that the rotating plate made of the memory metal material cannot be bent and connected with the conductor layer, the spring is in an original long state without receiving the effect of current, and after the temperature of the ionic liquid rises to the metamorphosis temperature of the memory metal material after absorbing heat, the rotating plate is bent due to the property of the rotating plate and is contacted with the conductor layer, so that two ends of the spring are connected with the battery in parallel;

4. meanwhile, negative pressure is input into the liquid cavity under the action of air pressure when the conductor sliding block moves, the liquid cavity is filled with liquid, the two ends of the liquid cavity are sealed by the breathable films, so that external gas is introduced into the breathable films, moves in the liquid cavity and finally enters the accommodating groove, and meanwhile, air on the other side of the conductor sliding block is compressed into the liquid cavity, so that the airflow flux of the liquid cavity is increased, the temperature of the liquid taken away by the external air is facilitated, and the heat exchange efficiency with the outside is improved;

5. after the rotating plate is connected with the conductor layer, the spring is in a reciprocating motion state under the action of a magnetic field generated by the spring elasticity and the spiral current in a period of time, so that the air is always in the liquid cavity in the period of time, the heat exchange effect is realized, and the balance is finally kept.
