[0019] Reference Figure 1 to Figure 6, which is the first embodiment of the present invention, proposes an Internet of Things intelligent circuit breaker for electric vehicle charging facilities, including: a circuit breaker body 1, having a mounting groove 101; an air inlet member 5, arranged in the mounting groove 101, the air inlet member 5 is used to ventilate the circuit breaker body 1; an air inlet pipe 2 is arranged in the mounting groove 101, one end of the air inlet pipe 2 is connected to the outside, and the other end is connected to the air inlet member 5; an air intake treatment member 6 is arranged in the air intake pipe 2, the air intake treatment member 6 divides the air intake pipe 2 into a first air intake channel 203 and a second air intake channel 202, after the first air intake channel 203 is closed, the second air intake channel 202 is opened, the first air intake channel 203 is used to pass humid air, and the second air intake channel 202 is used to pass dry air; a branch pipe 3, one end of which is connected to the air inlet member 5, and the other end is connected to the first air intake channel 203, after the first air intake channel 203 is closed, the branch pipe 3 is used to blow hot air to the first air intake channel 203. In the above scheme, a mounting groove 101 is provided on the outside of the circuit breaker body 1 for mounting the air inlet member 5, the air inlet pipe 2 and related control components. The mounting groove 101 is located on the outside of the circuit breaker body 1, and the air inlet member 5, the air inlet pipe 2 and related control components do not affect the normal operation of the inside of the circuit breaker body 1 after installation. The circuit breaker body 1 has the basic functions of overload protection, short circuit protection and leakage protection of traditional circuit breakers, and integrates the Internet of Things module, which can realize functions such as remote monitoring, data collection and intelligent management.

[0020] The air inlet 5 is installed in the mounting groove 101, and its main function is to ventilate the circuit breaker body 1, which can quickly replace the internal hot air, achieve air cooling, and ensure that the internal electrical components can get good heat dissipation. The air inlet 5 can be a fan, and the specific selection should be determined according to the power and heat dissipation requirements of the circuit breaker. The air inlet 5 is connected to the air inlet pipe 2 and the branch pipe 3, and the air entering the circuit breaker body 1 is regulated by controlling the opening and closing of different channels. The air inlet pipe 2 is arranged in the mounting groove 101, one end is connected to the outside world, and the other end is connected to the air inlet 5. The function of the air inlet pipe 2 is to introduce the outside air into the circuit breaker body 1 to provide the electrical components with the air required for heat dissipation. An air intake processing part 6 is arranged in the air inlet pipe 2, which divides the air inlet pipe 2 into a first air inlet channel 203 and a second air inlet channel 202. When the external environment is humid or the air is humid, the first air inlet channel 203 is used to pass humid air and perform simple adsorption treatment on the water vapor in the air. The second air inlet channel 202 is used to pass dry air with a large air intake volume, which is suitable for situations where rapid heat dissipation is required.

[0021] Under different environmental conditions, the appropriate air intake channel can be selected by controlling the change of the air intake processing member 6. The air intake processing member 6 is installed in the air intake pipe 2, and its function is to divide the air intake pipe 2 into two independent air intake channels. By moving the air intake processing member 6, the opening and closing of different channels can be realized. When the external environment is humid, the first air intake channel 203 is opened and the second air intake channel 202 is closed. The humid air is processed by the first air intake channel 203 to ensure that the air entering the circuit breaker body 1 is dry.

[0022] Working principle: Under normal circumstances, when the external environment is dry, the air intake processing part 6 controls the first air intake channel 203 to be closed and the second air intake channel 202 to be opened. The outside air enters the air intake pipe 2 through the second air intake channel 202, and then enters the circuit breaker body 1 through the air intake part 5, providing the air required for heat dissipation for the electrical components. The air intake part 5 continuously ventilates the circuit breaker body 1 to ensure internal air circulation and take away the heat generated by the electrical components. At the same time, the Internet of Things module of the circuit breaker body 1 monitors the working status and environmental parameters of the circuit breaker in real time, and transmits the data to the remote monitoring center to realize the intelligent management of the charging facilities. When the external environment is humid, the air intake processing part 6 controls the first air intake channel 203 to be opened and the second air intake channel 202 to be closed. At the same time, the valve on the branch pipeline 3 is closed to prevent hot air from entering the first air intake channel 203. The humid air from the outside enters the circuit breaker body 1 after being processed by the first air intake channel 203.

[0023] Since dry air flows through the second air inlet channel 202, the influence of humid air on the electrical components can be effectively avoided. When the first air inlet channel 203 needs to be dried, the air inlet processing component 6 controls the first air inlet channel 203 to be closed, and the second air inlet channel 202 is opened. At the same time, the valve on the branch pipe 3 is opened, the air inlet component 5 is reversed, and the air inlet component 5 blows hot air into the branch pipe 3. The hot air enters the first air inlet channel 203 through the branch pipe 3, and dries the humid first air inlet channel 203. The dried first air inlet channel 203 can be reopened when needed to provide the circuit breaker body 1 with the air required for heat dissipation.

[0024] The IoT smart circuit breaker for electric vehicle charging facilities should be installed in a suitable position of the charging facility to ensure that the air intake pipe 2 and the branch pipe 3 can be well connected with the external environment. At the same time, attention should be paid to the firmness and sealing of the installation to prevent external dust and moisture from entering the circuit breaker body 1. During the installation process, the various components should be correctly connected in accordance with the requirements of the instructions, and necessary debugging and testing should be carried out to ensure the normal operation of the circuit breaker. Regularly maintain and inspect the circuit breaker, including cleaning the air intake pipe 2, branch pipe 3 and air intake treatment part 6, checking the working status of the air intake part 5 and the valve, and ensuring the normal operation of each component. Regularly check the IoT module of the circuit breaker to ensure that it can transmit data and receive remote control instructions normally. If necessary, the IoT module can be upgraded and maintained to improve its performance and stability. In a humid environment, the monitoring and maintenance of the circuit breaker should be strengthened to promptly discover and deal with possible problems. If the first air intake channel 203 is found to be wet or blocked, it should be dried in time to ensure the normal operation of the circuit breaker.

[0025] In summary, this device can effectively solve the problem that electric vehicle charging facilities are affected by humidity and temperature changes in open air environments. The intelligent circuit breaker has functions such as remote monitoring, data collection and intelligent management, which can improve the safety and reliability of charging facilities and provide strong support for the popularization and development of electric vehicles.

[0026] Furthermore, the air intake treatment component 6 includes: a first opening and closing cylinder 601, which is arranged on one side of the air intake pipe 2; a second opening and closing cylinder 602, which is slidably arranged on the other side of the air intake pipe 2, and the first opening and closing cylinder 601 and the air intake pipe 2 are coaxially arranged; the first opening and closing cylinder 601 and the second opening and closing cylinder 602 respectively have a plurality of deflection plates 603, the number of the deflection plates 603 of the first opening and closing cylinder 601 and the number of the deflection plates 603 of the second opening and closing cylinder 602 are the same, and the deflection plates 603 of the first opening and closing cylinder 601 and the deflection plates 603 of the second opening and closing cylinder 602 are staggered; a treatment layer 604, which is arranged on the outer surface of the deflection plate 603 of the first opening and closing cylinder 601, and the treatment layer 604 is used for absorbing moisture and removing impurities.

[0027] In the above scheme, the first opening and closing cylinder 601 is arranged on one side of the air intake pipe 2 and is arranged coaxially with the air intake pipe 2 to ensure a stable position. It should be noted that the specifications of the first opening and closing cylinder 601 and the second opening and closing cylinder 602 are consistent and arranged relatively. When the first opening and closing cylinder 601 and the second opening and closing cylinder 602 are completely closed, the first opening and closing cylinder 601 and the second opening and closing cylinder 602 are both conical. When the first opening and closing cylinder 601 and the second opening and closing cylinder 602 are fully opened, they are cylindrical. When the first opening and closing cylinder 601 and the second opening and closing cylinder 602 are conical, the first air intake channel 203 is in an open state. When the first opening and closing cylinder 601 and the second opening and closing cylinder 602 are cylindrical, the second air intake channel 202 is in an open state. In addition, the first opening and closing cylinder 601 and the second opening and closing cylinder 602 are both connected to the inner wall of the air intake pipe 2 through a column, and the column does not affect the normal flow of air in the air intake pipe 2.

[0028] The second opening and closing cylinder 602 is slidably disposed on the other side of the air intake pipe 2, and the second opening and closing cylinder 602 can change its relative position with the first opening and closing cylinder 601 by sliding. The first opening and closing cylinder 601 and the second opening and closing cylinder 602 are respectively provided with a plurality of deflection plates 603, and the number of deflection plates 603 of the two are the same, but are arranged in a staggered manner. This staggered arrangement enables all the deflection plates to bite each other when the first opening and closing cylinder 601 and the second opening and closing cylinder 602 are close to each other, so as to form a complete cylindrical second air intake passage 202 with good sealing performance.

[0029] By controlling the deflection and movement of the deflection piece 603, the opening and closing of different air intake channels in the air intake pipe 2 can be accurately controlled in different states. When the deflection pieces 603 of the two opening and closing cylinders are completely separated and each is closed in a conical shape, the second air intake channel 202 can be closed and the first air intake channel 203 can be opened at the same time; when the action is opposite, the second air intake channel 202 can be opened.

[0030] In addition, a treatment layer 604, such as a drying layer or a sponge layer, is provided on the outer surface of the deflection piece 603 of the first opening and closing cylinder 601, which is mainly used for dehumidification. However, it is found in practice that the rough surface of the treatment layer 604 and the necking section 201 with a special structure can also effectively remove dust. The treatment layer 604 has a powerful moisture absorption and impurity removal function. In a humid environment, the treatment layer 604 can effectively absorb moisture in the air, prevent humid air from entering the circuit breaker body 1 driven by the air inlet 5, and avoid damage to the internal electrical components. At the same time, the treatment layer 604 can also remove impurities in the air, such as dust, particulate matter, etc., to ensure that the air entering the circuit breaker body 1 is clean, thereby improving the working stability and service life of the electrical components.

[0031] First, through the sliding of the first opening and closing cylinder 601 and the second opening and closing cylinder 602 and the staggered arrangement of the deflection plate 603, the opening and closing of different air intake channels in the air intake pipe 2 can be controlled extremely accurately to meet the needs under different environmental conditions. Secondly, the efficient moisture absorption and impurity removal function of the treatment layer 604 can effectively protect the electrical components inside the circuit breaker body 1, greatly improving the reliability and stability of the charging facilities. Furthermore, the design of the entire air intake treatment part 6 enables the circuit breaker to flexibly adjust the air intake channel and air treatment method according to actual conditions to adapt to various working environments and needs. Whether in areas with large temperature differences between day and night or in areas with high humidity, this intelligent circuit breaker can effectively adjust the air entering the circuit breaker body 1 through the air intake treatment part 6, providing reliable protection for the stable operation of electric vehicle charging facilities.

[0032] Furthermore, the cross-section of the deflection plate 603 is triangular; the second air inlet channel 202 is cylindrical, and after the second opening and closing tube 602 approaches the first opening and closing tube 601, the deflection plate 603 of the first opening and closing tube 601 and the deflection plate 603 of the second opening and closing tube 602 engage with each other to form the second air inlet channel 202; after the second opening and closing tube 602 moves away from the first opening and closing tube 601, the first opening and closing tube 601 and the second opening and closing tube 602 are both closed, and the first opening and closing tube 601 and the second opening and closing tube 602 are both conical.

[0033] In the above scheme, when the second opening and closing cylinder 602 is away from the first opening and closing cylinder 601, the first opening and closing cylinder 601 and the second opening and closing cylinder 602 are both closed, and in the closed state, the first opening and closing cylinder 601 and the second opening and closing cylinder 602 are both conical. This conical design can not only better block the entry of external air in the closed state, but also has a certain stability in structure. At this time, the first air inlet channel 203 is opened, and the cooperation of the conical first opening and closing cylinder 601, the second opening and closing cylinder 602 and the inner wall of the air inlet pipe 2 can achieve the change of the air flow rate entering the air pipe. The first opening and closing cylinder 601 and the second opening and closing cylinder 602 are in a conical state, which can effectively protect the electrical components inside the circuit breaker body 1 and avoid being adversely affected by the external environment.

[0034] Furthermore, the inner wall of the intake pipe 2 near the inner wall of the intake processing component 6 has a plurality of necked sections 201, and the plurality of necked sections 201 are arranged at intervals, and a first intake channel 203 is formed between the outer wall of the first opening and closing cylinder 601, the outer wall of the second opening and closing cylinder 602 and the inner wall of the intake pipe 2.

[0035] In the above scheme, the inner wall of the air inlet pipe 2 near the air inlet processing part 6 has several necking sections 201, and these necking sections 201 are arranged at intervals and arranged neatly. When the first opening and closing cylinder 601 and the second opening and closing cylinder 602 are in the closed position, the first air inlet channel 203 is formed between the outer wall of the first opening and closing cylinder 601, the outer wall of the second opening and closing cylinder 602 and the inner wall of the air inlet pipe 2. The existence of several necking sections 201 not only helps to clarify the boundary of the first air inlet channel 203, but also can adjust the flow speed and flow rate of air in the first air inlet channel 203 to a certain extent. When the first air inlet channel 203 is needed, the necking section 201 can play a certain role in guiding the air to enter the circuit breaker body 1 more smoothly. When the first air inlet channel 203 is closed, the necking section 201 can cooperate closely with the first opening and closing cylinder 601 and the second opening and closing cylinder 602 to effectively prevent air from entering the first air inlet channel 203.

[0036] Furthermore, it also includes: a deflection drive member 7, which has a plurality of deflection drive members 7, the number of which is the same as the number of deflection plates 603, each deflection drive member 7 corresponds to a deflection plate 603, and the deflection drive member 7 is used to drive the deflection plate 603 to deflect. The first opening and closing cylinder 601 also has a fixed ring, which is connected to the inner wall of the air intake pipe 2 through a column, and each deflection plate is hinged to the fixed ring, and each deflection drive member 7 includes: an arc guide rail, one end of which is arranged on the fixed ring, and the other end passes through and extends out of the deflection plate, and the deflection plate has a rotating wheel, which is slidably arranged in the arc guide rail; a driving motor, which is used to drive the rotating wheel to slide along the arc guide rail to realize the opening and closing of the deflection plate.

[0037] In the above scheme, the number of deflection drive members 7 is the same as the number of deflection plates 603, and each deflection drive member 7 corresponds to a deflection plate 603. The deflection drive member 7 can accurately drive the deflection plate 603 to deflect according to different environmental conditions and work requirements. When it is necessary to switch the air intake channel, the deflection drive member 7 can respond quickly, adjust the angle and position of the deflection plate 603, and realize the opening and closing switching of the first air intake channel 203 and the second air intake channel 202. For example, when the external environment is dry, the deflection drive member 7 will drive the deflection plate 603 to deflect, so that the first opening and closing cylinder 601 and the second opening and closing cylinder 602 cooperate with each other, close the first air intake channel 203, and open the second air intake channel 202 at the same time, to ensure that only dry air enters the circuit breaker body 1. The air intake processing system is made more intelligent and automated, and the air intake channel can be adjusted in real time according to actual conditions, providing more reliable protection for the stable operation of electric vehicle charging facilities. At the same time, the one-to-one correspondence between the multiple deflection driving members 7 and the deflection plates 603 also ensures that the movement of each deflection plate 603 is accurate and reliable, thereby improving the working efficiency and stability of the entire system.

[0038] Furthermore, it also includes: a moving driving member 8, which is arranged on the air inlet pipe 2, and the moving driving member 8 is transmission-connected with the second opening and closing cylinder 602, and the moving driving member 8 is used to drive the second opening and closing cylinder 602 to approach or move away from the first opening and closing cylinder 601. The moving driving member 8 includes: a lead screw, which is threadedly connected to the middle part of the second opening and closing cylinder 602, and the end of the lead screw is arranged on the first bevel gear, and also includes: a second bevel gear, which is driven to rotate by a driving motor to realize the forward and reverse rotation of the lead screw, thereby realizing the linear movement of the second opening and closing cylinder 602.

[0039] In the above solution, the mobile driving member 8 can accurately drive the second opening and closing cylinder 602 to approach or move away from the first opening and closing cylinder 601 according to different working requirements. When the air inlet channel needs to be switched, the mobile driving member 8 can respond quickly to control the position of the second opening and closing cylinder 602 to realize the opening and closing switching of the first air inlet channel 203 and the second air inlet channel 202.

[0040] Furthermore, it also includes: a heat sink 9, which has a plurality of heat sinks 9, which are arranged axially along the air inlet pipe 2, each heat sink 9 is wavy, one end of each heat sink 9 is arranged in the circuit breaker body 1, and the other end is arranged in the air inlet pipe 2, and the heat sink 9 is used to transfer the heat in the circuit breaker body 1 to the air inlet pipe 2.

[0041] In the above scheme, a number of heat sinks 9 are also provided in the IoT intelligent circuit breaker for electric vehicle charging facilities. These heat sinks 9 are arranged axially along the air inlet pipe 2, and each heat sink 9 is wavy. This shape design can increase the surface area of ​​the heat sink 9 and improve the heat dissipation efficiency. One end of each heat sink 9 is arranged in the circuit breaker body 1, and the other end is arranged in the air inlet pipe 2. Through this connection method, the heat sink 9 can effectively transfer the heat in the circuit breaker body 1 to the air inlet pipe 2. For example, in winter, the outside air is cold. When the air enters the circuit breaker body 1 through the air inlet pipe 2, it will take away the heat on the heat sink 9, and will also simply preheat the incoming air to ensure that the temperature inside the circuit breaker fluctuates within a smaller range, prevent the components inside the circuit breaker from being frozen, and also achieve heat dissipation of the circuit breaker.

[0042] The wavy heat sink 9 increases the contact area with the air, so that the heat can be dissipated more quickly. Secondly, the heat sink 9 transfers the heat in the circuit breaker body 1 to the air inlet pipe 2, and uses the air flow in the air inlet pipe 2 to dissipate heat, thereby improving the heat dissipation effect. Furthermore, the arrangement of multiple heat sinks 9 can distribute the heat more evenly, avoid local overheating, and ensure the stable operation of the circuit breaker.

[0043] Furthermore, it also includes: a sensor 13, which has a plurality of sensors 13, and the plurality of sensors 13 are all arranged on the intake pipe 2, and the sensors 13 are used to monitor the temperature and humidity of the external environment.

[0044] In the above scheme, the sensor 13 can accurately monitor the temperature and humidity of the external environment. For electric vehicle charging facilities, changes in the temperature and humidity of the external environment have a significant impact on its internal electrical components, especially circuit breakers. By real-time monitoring of the temperature and humidity of the external environment, the intelligent circuit breaker can adjust the air intake processing method in time according to actual conditions to better protect the internal electrical components. When the sensor 13 detects that the temperature of the external environment is too high or the humidity is too high, the intelligent circuit breaker can automatically start the corresponding protection measures.

[0045] The arrangement of several sensors 13 can more comprehensively monitor the environmental conditions around the intake pipe 2, and improve the accuracy and reliability of monitoring. At the same time, the sensor 13 is connected to the control system of the intelligent circuit breaker, and can transmit the monitored data to the control system in real time, so that the control system can make fast and accurate decisions, and realize the intelligent management of the electric vehicle charging facilities.

[0046] Furthermore, it also includes: a controller 12, which is arranged on the intake pipe 2, and the controller 12 is connected to the sensor 13, the deflection drive component 7 and the movement drive component 8. The controller 12 is used to further include: an electromagnetic valve 4, which is arranged on the branch pipe 3, and the electromagnetic valve 4 is used to control the opening and closing of the branch pipe 3.

[0047] In the above scheme, in the IoT intelligent circuit breaker for electric vehicle charging facilities, the setting of the controller 12 plays a key regulatory role. The controller 12 is arranged on the air inlet pipe 2, and is connected to the sensor 13, the deflection drive 7 and the mobile drive 8. The sensor 13 transmits the monitored external environmental temperature and humidity data to the controller 12. The controller 12 analyzes and judges based on these data, and then issues corresponding instructions to the deflection drive 7 and the mobile drive 8. For example, when the external humidity is too high, the controller 12 controls the mobile drive 8 to drive the second opening and closing cylinder 602 away from the first opening and closing cylinder 601, closes the second air inlet channel 202, and controls the deflection drive 7 to adjust the position of the deflection plate 603 to ensure the smooth flow of the first air inlet channel 203, so that dry air can enter the circuit breaker body 1. This can effectively prevent the damage of humid air to electrical components.

[0048] Through the coordinated control of the sensor 13, the deflection drive 7, the mobile drive 8 and the electromagnetic valve 4 by the controller 12, the intelligent circuit breaker can achieve precise management of the air intake channel and rapid response to environmental changes, greatly improving the reliability and stability of the electric vehicle charging facilities.

[0049] Secondly, when the outside temperature is suitable, the air intake part is backblown, at this time the electromagnetic valve 4 is opened, the first air intake channel 203 is closed, and it also includes the spiral flow channel 10 and the air hole 11. The air flow is connected to the first air intake channel 203. The branch pipe 3 can transfer the heat in the circuit breaker to the surface of the treatment layer 604 to achieve drying of the treatment layer 604.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
