Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

As shown in fig. 1 and fig. 2, the intelligent protection charging cabinet provided by this embodiment includes the charging cabinet body 1, and the cabinet body 1 can be provided with a plurality of battery charging bins 2, and the charging bins 2 can be spliced as required. At present, charging cabinets with 8, 10, 12 and 16 cabins can be spliced out as required. Other numbers of charging devices for charging the bins 2 can be provided according to the needs of the user. The device has the characteristics of simple installation and small occupied area, and is suitable for various environments such as open air, carport, indoor environment and the like.

The whole intelligent protection charging cabinet is externally composed of a plurality of battery charging bins 2 and at least one control room 3. The control room 3 may be located at the middle portion of the cabinet 2, or may be located at both sides of the cabinet 2. More often, the control room 3 is located at the top of the cabinet and has a flip-up top cover. The control room 3 is respectively connected with the plurality of charging bins 2 in a communication way. The upper part of the control room 3 can be provided with a touch display screen for user operation, and the card swiping device is arranged at the lower part of the display screen; canopy, lighting lamp house and surveillance camera head set up in the cabinet top that charges.

Each charging bin 2 is internally provided with charging facilities for charging batteries, and the charging facilities are connected with a power supply through a control room 3 and controlled by the control room 3.

Each charging bin 2 is a place where a user actually charges a battery, and is provided with not only a charging facility but also a lighting facility, a ventilation facility, a fire fighting facility, and the like.

The intelligent protection system 4 is connected with the main power supply of the charging cabinet in series to control the on-off of the power supply of the charging facilities in each charging bin 2. When the cabinet door of the charging bin 2 is opened, the charging power supply of the charging bin 2 is cut off for safety. If the charging bin 2 is also provided with other lighting power supplies, ventilation facilities, etc., the power supply may not be cut off.

The charging bin 2 is a metal closed space of a cuboid, the cabinet door adopts an electromagnetic door lock, the control door of the control system can be opened, the safety of the battery of the user electric bicycle placed in the box can be guaranteed, and the designed space size can meet various batteries of the electric bicycles on the market.

The electromagnetic door lock is matched with the grounding tripping module 6, so that the on-off of the charging power supply along with the opening and closing of the door can be realized. The state of the grounding tripping module 6 is switched to a tripping state when the cabinet door of the corresponding charging bin 2 is opened; and when the cabinet door of the charging bin 2 is closed, the cabinet door is switched to a closed state.

The whole intelligent protection system 4 can be a set of tripping system for controlling the on-off of the circuit according to the cabinet door of the charging bin 2. The trip unit is a device mechanically coupled to the circuit breaker for releasing the hold-down mechanism and automatically opening the circuit breaker. The grounding tripping module 6 may be a travel switch or a microswitch arranged on the cabinet door of the charging bin 2. The protection control module 5 may be a power contactor or a shunt release connected in series to a charging facility power circuit inside the charging bin 2.

The power supply contactor or the shunt release is controlled to carry out on-off setting on the power supply circuit through the state change of the travel switch or the micro switch when the cabinet door is opened or closed. The two are connected through communication connection or directly connected with a low-voltage circuit.

Taking the shunt release as an example, the shunt release is an accessory for remotely controlling the shunt. When the power supply voltage is equal to any voltage between 70% and 110% of the rated control power supply voltage, the circuit breaker can be reliably disconnected. The shunt release is a short-time working system, the energizing time of the coil generally cannot exceed 1S, otherwise the coil can be blown. The plastic shell circuit breaker is characterized in that a microswitch is connected in series with the shunt release for preventing the coil from being burnt, when the shunt release is attracted by the armature, the microswitch is switched from a closed state to an open state, and because a control circuit of a power supply of the shunt release is cut off, even if a button is manually pressed, the shunt coil is not electrified any more all the time, so that the coil burning loss is avoided. When the breaker is buckled and closed again, the micro switch returns to the closed position again. The shunt release is essentially a tripping coil plus release, and a specified voltage is applied to the shunt release coil, so that the circuit breaker is tripped and is switched off.

Specifically, the low-voltage circuit breaker generally comprises a release, a contact system, an arc extinguishing device, a transmission mechanism, a base frame, a shell and the like, when the low-voltage circuit breaker is put into operation, a main contact is closed, a free release mechanism locks the main contact at a closed position, and various releases enter an operating state. The release can include:

the electromagnetic release is connected in series with the protected circuit. When normal current passes through the circuit, the electromagnetic force generated by the electromagnet is smaller than the pulling force of the counterforce spring, the armature cannot be attracted by the electromagnet, and the circuit breaker normally operates. When the switch is closed or a short-circuit fault occurs in a circuit, the current exceeds a plurality of times of the normal current, the electromagnetic force generated by the electromagnet is larger than the acting force of the counterforce spring, and the armature is attracted by the electromagnet and pushes the free tripping mechanism to release the main contact through the transmission mechanism. The main contact is separated to cut off the circuit under the action of the opening spring to play a short-circuit protection role.

The thermal trip is connected in series with the protected circuit. When normal current passes through the circuit, the heating element generates heat to enable the bimetallic strip to bend to a certain degree and just contact the transmission mechanism and reach a dynamic balance state, and the bimetallic strip does not continue to bend. If an overload phenomenon occurs or the switch is closed, the current in the circuit is increased, the bimetallic strip is continuously bent, the free tripping mechanism is pushed by the transmission mechanism to release the main contact, the main contact is separated under the action of the opening spring, and the cut-off circuit plays a role in overload protection.

The voltage-loss release is connected in parallel with the power supply of the circuit breaker and can play the role of undervoltage and zero-voltage protection. When the power supply voltage is normal, the operating handle is pulled, the normally open auxiliary contact of the circuit breaker is closed, the electromagnet is electrified, the armature is attracted by the electromagnet, the free tripping mechanism can lock the main contact at the switching-on position, and the circuit breaker is put into operation. When the power supply side is in power failure or the power supply voltage is too low, the electromagnetic force generated by the electromagnet is not enough to overcome the pulling force of the counterforce spring, the armature is pulled upwards, the free tripping mechanism is pushed by the transmission mechanism to enable the circuit breaker to be tripped, and the undervoltage and zero-voltage protection effects are achieved. Normally closed buttons connected in series in the solenoid loop of the no-voltage release can be used for opening the brake.

The shunt release is used for remotely operating the opening control of the low-voltage circuit breaker. The electromagnetic coil is connected in parallel with the power supply side of the low-voltage circuit breaker. When the switching-off operation is needed, the normally open button is pressed to enable the electromagnet of the shunt release to be electrified and attract the armature, and the free tripping mechanism is pushed through the transmission mechanism to enable the low-voltage circuit breaker to be switched off.

When two or more than two types of trippers are simultaneously installed on one low-voltage circuit breaker, the low-voltage circuit breaker is called to be provided with a compound tripper. In specific use, shunt tripping is mainly used for control, and voltage loss tripping is mainly used for protection.

In this embodiment, whether the tripper is tripped or not is controlled by the travel switch or the microswitch, so that when the cabinet door of the charging bin 2 is opened, the charging facility inside the charging bin 2 is powered off.

When the travel switch or the microswitch is connected with the release, a relay is generally required to be connected in series to protect a circuit.

In order to strengthen the protection of the whole charging cabinet, the intelligent protection charging cabinet also comprises a standby power supply for emergency power supply. Namely, when the power supply is in a problem, a standby power supply can be provided to continue the charging operation. Or, the standby power supply can be only used for supplying power to the control room 3, so that the normal work of the control system of the whole charging cabinet is ensured.

The intelligent protection charging cabinet further comprises an overload protector for protecting the battery from overload. Generally, the charging power source of the electric vehicle cannot provide overload protection, and thus it is required to provide overload protection at the charging facility of the charging bin 2 to effectively protect the battery of the user. The intelligent protection charging cabinet further comprises an overload protector for protecting the battery from overload.

Furthermore, the voltage, current, etc. of the battery charge need to be monitored to ensure that the voltage, current are within normal ranges. The intelligent protection charging cabinet also comprises a voltage/current monitoring device for monitoring the voltage/current in the charging process of the battery.

When monitoring that overload occurs or the voltage and the current are not in the normal range, the power supply of the charging facility of the corresponding charging bin 2 is cut off through the protection control module 5.

A system interface control board may be provided inside the control room 3. The system interface control board is connected with the electromagnetic lock and the charging socket control relay of each charging bin 2, controls the opening of the electromagnetic lock, and controls the opening and closing of the charging socket control relay. When the electromagnetic lock of the charging bin 2 is opened, the charging socket relay is disconnected, so that unnecessary charging danger is avoided.

And a fire-fighting interface, an electromagnetic valve, a connecting hose and a fire-extinguishing spray head are arranged in each charging bin 2 or the control room 3. The fire-fighting interface is connected with the special fire-fighting water source interface. The electromagnetic valve is used for controlling the opening or closing of the fire extinguishing spray header. When the electromagnetic valve is opened, the fire extinguishing spray header starts spraying. The connecting hose is used for connecting the fire extinguishing spray head and a fire fighting water source. The fire extinguishing spray headers are arranged inside each charging bin 2 and the control room 3 in groups, and fire in different charging bins can be treated respectively to perform different spraying.

In fact, the fire fighting water source can be connected to the spray header through the connecting hose, and when a fire occurs, the fire fighting spray header is opened through the control solenoid valve, and then the fire fighting water source is conveyed to the fire fighting spray header through the hose to be disposed.

Due to the particularity of electric appliance fire protection, a fire protection water source can be replaced by a special gas fire extinguisher, and the gas fire extinguisher or a gas storage tank is connected to a connecting hose to realize automatic control on/off.

To sum up, the utility model provides an intelligence protection cabinet that charges can conveniently carry out centralized management to electric bicycle's battery, can be to every storehouse of charging auto-power-off when opening the cabinet door, and the electric shock that probably causes when avoiding the user to charge is dangerous. The release can monitor the battery charging state simultaneously, is full of and does not transship, avoids unnecessary conflagration hidden danger and the harm to battery ben examination. Meanwhile, a standby battery is designed, and normal operation of the system can be guaranteed after power failure due to unknown reasons. In addition, by monitoring the voltage/current, illegal operation can be found in time, and a certain early warning effect is achieved.
