Description

Technical Field

[0001] The present invention relates to the technical field of engineering construction, and in particular to an encrypted intelligent time-controlled electric tool charging cabinet. Background Art

[0002] At present, during the temporary power construction at the construction site, the construction unit provides power tool charging facilities, namely power tool charging cabinets, for the labor workers to ensure the safety and convenience of power use for the construction workers at the construction site.

[0003] The electric tool charging cabinets provided at the construction site generally use a system of one circuit breaker and one leakage protector as the electrical switch with a five-hole socket connected to connect the small electric tool charger. However, in actual use on site, labor workers often forget to charge the electric tools for other reasons, and long-term charging can cause the small charging tool battery to short-circuit and catch fire, posing a safety hazard of battery explosion and fire.

[0004] The invention patent with application number 201811282192.4 discloses a charging cabinet, which relates to the technical field of battery charging equipment. A charging cabinet, used for battery charging, comprises: a cabinet body and a plurality of battery charging compartments, wherein the plurality of battery charging compartments are arranged in the cabinet body; the battery can be placed in the battery charging compartment, and the battery can be taken out of the battery charging compartment; the battery can be connected to the charging terminal in the battery charging compartment to achieve charging. The purpose of the present invention is to provide a charging cabinet to alleviate the problem in the prior art that people's riding is affected by factors such as poor battery life, long charging time, and fast battery loss.

[0005] The above technology designs a charging cabinet for replacing rechargeable batteries to achieve the goal of increasing battery life, but it still does not cut off the power to the charged battery. That is, in actual use, long-term power connection may cause safety hazards. Now a technology is needed that can actively cut off the power to the charged power tool. Summary of the invention

[0006] The present invention provides an encrypted intelligent time-controlled electric tool charging cabinet, which can solve the problem that a fully charged electric tool cannot be automatically powered off.

[0007] In order to solve the above technical problems, the present application provides the following technical solutions: 1. An encrypted intelligent time-controlled electric tool charging cabinet, comprising:

[0008] Cabinet: The cabinet is divided into several compartments; each compartment is equipped with a cabinet door;

[0009] Charging circuit: installed in the cabinet, the charging circuit includes a power supply, a main circuit breaker, a main leakage protector, a time relay and a charging socket connected in series;

[0010] Control circuit: includes a PLC processing module, a password controller, a time relay, a buzzer and an electronic door lock connected in series in sequence; the electronic door lock is installed on the cabinet door and is used to receive control instructions from the PLC processing module to complete the opening or closing of the cabinet door; the buzzer makes a sound after the charging device is connected to the power and starts charging to remind the user that charging has started; the time relay is used to control the power-on time of the charging circuit.

[0011] The basic principle and beneficial effects of this solution: The charging cabinet is composed of a cabinet, switch components, PLC processing modules, etc. The cabinet is painted inside and outside. The charging circuit is output from the power supply through the main circuit breaker and the main leakage protector to the time relay and then leads to the five-hole socket; the control circuit is led from the password controller to the time relay control circuit, and then connected to the buzzer and electronic door lock. This product can effectively reduce the fire hazard caused by the charging of power tools. The project electrical engineer sets the password for supervision and standardizes the use and management of small-scale power tools on site. The charging circuit and the control circuit are both powered by the power supply, and the power supply selects the mains; the mains passes through the main circuit breaker and the main leakage protector, and then supplies power to the charging circuit and the control circuit respectively. The charging cabinet is divided into multiple compartments, each compartment is equipped with a cabinet door, and the cabinet door is equipped with an electronic door lock. The electronic door lock is controlled by the password controller. After the password is entered correctly, the corresponding cabinet door is opened. The buzzer mainly serves as a reminder. After the user connects the charging device to the socket, the buzzer sounds, prompting the user that charging has begun. This solution controls the charging time of the charging circuit through a time relay, which can prevent the socket from being connected to the power supply for a long time after the device is charged, causing the device to be in a charging state all the time; through the use of a time relay, the charging time is controlled, and on the basis of ensuring that charging is completed, it also avoids the charging device being in a power supply state for a long time.

[0012] Furthermore, the time relay is a digital display time relay, and is also used to set the power supply time. When the PLC processing module recognizes that there is no charging device in the compartment, if the electronic door lock on the cabinet door of the corresponding cabinet is unlocked, the charging socket in the cabinet is powered and a countdown is set. The power supply is stopped after the countdown.

[0013] Beneficial effect: The digital display time relay is mainly used to display the remaining charging time.

[0014] Furthermore, it also includes a trigger relay connected to the charging circuit; if there is a device being charged in the compartment, the trigger relay will disconnect the charging circuit from the power supply of the charging socket.

[0015] Furthermore, it also includes a trigger relay connected to the charging circuit; if there is a device being charged in the compartment, the trigger relay will count down, and if the cabinet door is not closed within the threshold time, the charging circuit will disconnect the power supply of the charging socket.

[0016] Beneficial effects: Considering that in certain scenarios, such as when a tool that is being charged needs to be temporarily used, it is dangerous to open the door while the tool is still charging. In the face of such scenarios, the main solution is to install a relay with an automatic power-off function. Set the time relay to be linked with the door lock. When the door is opened, the time relay starts timing. Once it exceeds the set time and is not closed, the relay will cut off the power supply to achieve automatic power-off protection.

[0017] Furthermore, the electronic door lock includes a digital password input and a head portrait recognition input; and is used to open the corresponding cabinet door according to the input password or the recognized head portrait.

[0018] Beneficial effects: It is convenient to carry out hierarchical management. For example, when the users are workers, they can only open their own cabinet doors to charge. When the users are managers, they can open all cabinet doors for inspection through a unified password.

[0019] Furthermore, a visual window is provided on the cabinet door.

[0020] Beneficial effect: It is convenient to observe the charging status of the equipment in the cabinet from the outside.

[0021] Furthermore, the cabinet door is opened in a flat manner to open the compartment.

[0022] Beneficial effects: Considering the convenience of users charging and moving electric tools inside the charging compartment, the electric tool charging cabinet adopts a cabinet-type box with a flat door. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 This is a schematic diagram of the charging circuit and control circuit of the encrypted intelligent time-controlled electric tool charging cabinet. DETAILED DESCRIPTION

[0024] The following is further described in detail through specific implementation methods:

[0025] Embodiment 1 is as attached Figure 1 As shown,

[0026] Encrypted intelligent time-controlled electric tool charging cabinet, including:

[0027] Cabinet: The cabinet is divided into several compartments; each compartment is equipped with a cabinet door;

[0028] Charging circuit: installed in the cabinet, the charging circuit includes a power supply, a main circuit breaker, a main leakage protector, a time relay and a charging socket connected in series; the power transmission direction is DZ15-63A / 290 circuit breaker → 63A / 2P leakage short circuit breaker → 14-hole terminal block → 12 routes connected to DZ15L-32A / 2P leakage circuit breaker → DH48S digital display time relay (power transmission circuit) → 5-hole socket panel.

[0029] Control circuit: powered by a power supply, including a PLC processing module, a password controller, a time relay, a buzzer and an electronic door lock connected in series; the electronic door lock is installed on the cabinet door and is used to receive control instructions from the PLC processing module to open or close the cabinet door; the buzzer makes a sound to remind the user that charging has started after the charging device is connected to the power supply. The power transmission direction of the control circuit is: DZ15-63A / 290 circuit breaker → 63A / 2P leakage short circuit breaker → intelligent control module → password controller → 12 DH48S digital display time relays (control circuit) → buzzer → door lock switch (power off to open the door).

[0030] The time relay is a digital display time relay and is also used to set the power supply time. When the PLC processing module recognizes that there is no charging device in the compartment, if the electronic door lock on the cabinet door of the corresponding cabinet is unlocked, the charging socket in the cabinet is powered and a countdown is set. The power supply is stopped when the countdown is over.

[0031] It also includes a trigger relay connected to the charging circuit; if there is a device being charged in the compartment; the trigger relay will disconnect the charging circuit from the power supply of the charging socket. Considering the problem of charging small tools for labor workers at construction sites. Combined with the needs of the construction site, it is recommended to set it up in the outdoor area of ​​the workers' living area or the outdoor area of ​​the office area, and a dedicated person is responsible for management. The charging time can be customized as needed. This solution is customized for 2 hours; the box is made of 1.5MM thick galvanized iron sheet, which is sturdy, durable, and beautiful.

[0032] It also includes a trigger relay connected to the charging circuit; if there is a device being charged in the compartment; the trigger relay counts down, and if the cabinet door is not closed within the threshold time, the charging circuit will disconnect the power supply of the charging socket. Considering that in specific scenarios, such as when a tool being charged needs to be temporarily taken, the tool is still in the charging state when the door is opened at this time, which is dangerous. In the face of this scenario, it is mainly through the installation of a relay with an automatic power-off function, that is, the trigger relay immediately cuts off the power to the charging circuit or counts down for a period of time, for example, if the door is not closed for 1 minute, it will be powered off. Set the time relay to be linked with the door lock. When the door is opened, the time relay starts counting. Once it exceeds the set time and is not closed, the relay will cut off the power supply to achieve automatic power-off protection.

[0033] The electronic door lock includes a digital password input and a head portrait recognition input; it is used to open the corresponding cabinet door according to the input password or the recognition head portrait. The cabinet door is provided with a visual window. The cabinet door is opened in a flat opening manner to open the compartment.

[0034] In order to meet the needs of various construction site workers to charge small power tools. There are 10 charging ports, that is, 10 compartments, each with a size of 250*350*350, which basically meets the charging needs of all types of small construction tools. The top of the box is waterproof, so it can be placed indoors and outdoors; the electronic door lock design ensures that small power tools will not be taken wrong or lost during storage and retrieval; the buzzer reminder can also inform the user whether the charging action of the device has started.

[0035] The product made by this solution is originally an ordinary small electric tool charging cabinet with moderate cost. Some required components are added on the original basis. The cabinet is sturdy and durable, can be used for multiple projects, and old parts can be replaced separately after long-term use. The product has high efficiency. In addition, it can meet the project safety and green construction standards in terms of appearance and usage functions.

[0036] Embodiment 2

[0037] The difference between the second embodiment and the first embodiment is that: the electric tool is a drill, and a charging mold for the drill is also provided in the compartment. The shape of the charging mold matches the drill, and a temperature sensor is provided at the body of the mold and the position where the battery is placed, for capturing the temperature of the body and the battery; a fan is also provided in the compartment, and the fan parameters are adaptively selected according to actual usage; the fan faces the cabinet door, wherein the fan, the body, the battery, and the cabinet door are in the same straight line; the PLC processing module is also used to control the issuance of control instructions to control the start and stop of the fan; each compartment is provided with two temperature control switches, one of which is connected in series with the circuit where the single compartment is located (i.e. Figure 1 W1-W12 shown in the figure), another temperature control switch is connected in series in the main circuit (i.e. Figure 1), when the PLC processing module identifies that the temperature of the body exceeds the threshold, it starts the fan to cool it down. When the temperature drops below the threshold, it connects the power supply of the compartment to charge. During the charging process, if the battery heats up, the battery temperature gradually rises. At this time, the PLC data processing module controls the fan to start, and cools the battery during the charging process. If the temperature continues to rise and exceeds the threshold, the temperature control switch of the compartment is disconnected, and the charging is disconnected. When the temperature drops to normal temperature, the charging is resumed. After the charging is resumed, the fan is started synchronously. If the temperature exceeds the threshold again after charging for a period of time, the temperature control switch of the compartment is disconnected, and a repair signal is issued for maintenance personnel to inspect. If it is found that the temperature of multiple (3 or more) compartments exceeds the threshold at the same time, the temperature control switch of the main line is disconnected, and the power supply to the charging cabinet is stopped.

[0038] This solution can directly obtain the temperature of the drilling rig in the charging state by detecting the temperature of the machine body and the battery, and at the same time avoid directly charging the drilling rig at high temperature after it has just been processed, which may easily damage the battery. The fan can be set to cool down the fan. At the same time, blowing air towards the door can also gather dust and other impurities in the compartment to the door, which is convenient for subsequent cleaning and avoids dust flying around in the compartment. During the charging process, if the battery temperature gradually rises from normal temperature, for example, it rises by 5°C, the fan is started to cool it down. This process can effectively control the temperature of the battery to prevent it from rising sharply, and can also stabilize the charging efficiency of the battery and protect the battery life. When the charging temperature of a single compartment exceeds the threshold, the power supply of the corresponding compartment is disconnected. When the temperature in multiple compartments exceeds the threshold at the same time, there may be a problem with the power supply, so the main line power supply is disconnected to prevent circuit problems.

[0039] Embodiment 3

[0040] The difference between Example 3 and Example 2 is that the PLC data processor is also used to obtain the power status of the sockets in each compartment (an ammeter can be connected to the circuit in each compartment, and the PLC data processor obtains the value of the ammeter to determine whether the socket is powered on). When the door of the empty compartment is opened, the staff plugs in the power supply to charge the drilling rig. If the compartment is powered on normally (but charging has not officially started, it is necessary to judge the battery and body temperature and then confirm whether it is powered on by the temperature control switch), the buzzer will start to sound to prompt that the charging circuit is normal, and the staff can close the door and leave normally. Subsequently, when the temperature reaches the standard, the temperature control switch controls the socket to power on, and then starts charging the drilling rig.

[0041] This solution is more sensitive in reminding the staff of the charging status of the drilling rig on the basis of the first embodiment. The difference is that this solution actually reminds the power connection status of the compartment. If the compartment is powered, the staff will not supply power immediately after plugging in the charging plug of the drilling rig, but will first detect the temperature; but at this time, the compartment is in the power connection state, and the buzzer will sound to remind the staff that the power connection is successful, and they can directly close the door and leave. At this time, it is safer that the drilling rig has not started to be charged, but the staff has not received the instruction to enter the charging state. Different from the first embodiment in which charging starts and then reminding the staff to leave, it can better ensure the safety of the staff and the safety of the charging status of the drilling rig.
