Technical Field
[0001] The utility model belongs to the technical field of construction electricity, and in particular relates to an intelligent distribution box for electricity used on construction sites. Background Art
[0002] In the construction site operations such as shipbuilding and offshore oil platforms, welding, lighting, grinding and other operations are involved. These operations all require electricity as a power source. In order to meet the construction needs, a large number of distribution boxes need to be deployed on site to provide the necessary power source for on-site construction. Traditional distribution boxes only provide circuit distribution, overload and leakage protection functions, and do not have the capabilities of on-off control, data recording, remote management, etc. In the context of cost reduction, efficiency improvement, energy conservation and emission reduction, they have restricted the management of the site. For example, there is no one working on the site, but due to negligence, there are still electrical equipment working on the site, such as welding machines, lighting fixtures, etc., which often cause waste of electricity because they do not have the ability to on-off and detect. In the context of energy conservation and emission reduction, there is obviously room for improvement; the construction site is flexible and changeable, and the power supply is mainly open supply. There is a lack of power monitoring capabilities, which affects the feedback and allocation of the power system, resulting in uneven distribution of distribution boxes, and is not conducive to the statistics and control of the power cost of the project.
[0003] At the same time, the traditional distribution box is large in size, with low internal space utilization, and it also occupies the only space on the construction site, causing waste. At the same time, the large size of the distribution box is not conducive to on-site deployment and movement, which has caused certain difficulties for on-site construction. When the 220V power supply is used, workers directly operate the leakage protector by hand. There is dust and moisture on site, which is very likely to cause the risk of electric shock. At the same time, the power cord enters and exits from the bottom of the distribution box, and the wiring is chaotic, which is quite inconvenient to use. The door of the traditional distribution box is in the form of a double door, which is easy to be not closed. It is easy to be blown open by the wind during on-site use, causing rain and dust to enter and cause power safety.
[0004] Therefore, it is urgent to design an intelligent distribution box for electricity use on the construction site to solve the above-mentioned problems. Utility Model Content

For example, in the claims, any one of the claimed embodiments may be used in any combination.
[0026] Please refer to the attached Figure 1 To Attachment Figure 4 The utility model describes an intelligent power distribution box for electricity used on a construction site.
[0027] At present, the traditional distribution box is large in size, with low internal space utilization, and also occupies the only space on the construction site, causing waste. At the same time, the large size of the distribution box is not conducive to on-site deployment and movement, causing certain difficulties for on-site construction; when the 220V power supply is used, workers directly operate the leakage protector by hand, and there is dust and humidity on site, which is very likely to cause the risk of electric shock. At the same time, the power cord enters and exits from the bottom of the distribution box, and the wiring is chaotic, which is quite inconvenient to use. The door of the traditional distribution box is in the form of a double door, which is easy to be not closed. It is easy to be blown open by the wind during on-site use, causing rain and dust to enter and cause power safety.
[0028] Therefore, the distribution box includes a box body 1, a power supply socket 2 is provided on the box body 1, and the power supply socket 2 can be plugged with an external power supply plug, and a power supply wire management groove 22 is provided on the power supply socket 2. The cable of the external power supply plug is plugged into the power supply wire management groove 22, and the cable of the external power supply plug extends to the outside of the distribution box through the power supply wire management groove 22. A power supply cover plate 21 is provided on the box body 1, and the power supply cover plate 21 can rotate relative to the power supply socket 2. The power supply cover plate 21 has an installation state and a use state; when the power supply cover plate 21 is in the installation state, the power supply cover plate 2 1 is rotated to the outside of the power socket 2 so that the external power plug can be installed or removed; when the power cover 21 is in use, the power cover 21 covers the power plug, so that the power plug and the power socket 2 are protected, and rainwater is prevented from entering the power plug and the power socket 2, and the power cover 21 is fitted with the open end of the power cable groove 22 to limit the cable of the power plug, avoid the cable of the power plug from being squeezed and running around, and the wiring is beautiful, and at the same time, it is prevented from entering the distribution box along the cable of the power plug when it rains.
[0029] Preferably, a pin is fixedly connected to the power supply cover 21, and the power supply cover 21 is hinged to the box body 1 through the pin. In other embodiments of the utility model, a rotating shaft, a rotating rod, etc. can also be used as long as the power supply cover 21 can rotate relative to the box body 1.
[0030] The box body 1 is provided with a lighting interface 4 , and a lighting cable management groove 42 is provided on the lighting interface 4 . An external lighting cable can be plugged into the lighting cable management groove 42 , so that the external lighting cable is connected to the lighting unit in the box body 1 through the lighting cable management groove 42 .
[0031] A lighting cover 41 is provided on the lighting interface 4, and the lighting cover 41 is hinged to the box body 1 through a pin shaft. The lighting cover 41 can rotate relative to the lighting interface 4. The rotation of the lighting cover 41 can control whether the opening end of the lighting cable management groove 42 is opened or closed. After the lighting cover 41 is opened, the external lighting cables are passed into the box body 1 through the lighting cable management groove 42. After the lighting cover 41 is closed, the lighting cover 41 limits the lighting cables to avoid squeezing and running of the lighting cables, making the wiring beautiful. At the same time, it also prevents rainwater from entering the distribution box along the lighting cables when it rains.
[0032] A power switch 3 and a power indicator light are provided on the distribution box. The power switch 3 indirectly realizes connection control of the power socket 2 through a controller, so as to control whether the power socket 2 is powered by the power switch 3. The controller is electrically connected to the power indicator light, so that when the power socket 2 is powered, the power indicator light is on, and when the power socket 2 is powered off, the power indicator light is off. By setting the power switch 3, whether the power socket 2 is powered can be manually controlled, and by setting the controller, the strong current of the power supply circuit can be converted into weak current, thereby protecting the operator.
[0033] The distribution box is provided with a lighting switch 31 and a lighting indicator light. The lighting switch 31 indirectly realizes the connection control of the lighting unit through the controller, so as to control whether the lighting unit is powered by the lighting switch 31. The controller is electrically connected to the lighting indicator light, so that when the lighting unit is powered, the lighting indicator light is on, and when the lighting unit cancels the power supply, the lighting indicator light is off. By setting the lighting switch 31, it is possible to manually control whether the lighting unit is powered, and by setting the controller, the strong current of the lighting circuit is converted into weak current, thereby protecting the operator.
[0034] The box body 1 is fixedly connected with a supporting leg 11 , and the supporting leg 11 is fixedly connected with a roller to facilitate the movement of the box body 1 .
[0035] The specific number of rollers is four, and every two rollers are located at one end of the box body 1. The rollers at both ends of the box body 1 are perpendicular to each other, so that the box body 1 can be self-locking. Therefore, when moving the distribution box, one end of the distribution box is lifted so that the two rollers located in the same direction are in contact with the ground, and then the distribution box is moved. After placing the distribution box, the four rollers are perpendicular to each other in pairs, so that the rollers are automatically locked and fixed, preventing the distribution box from shifting.
[0036] In the implementation mode of the utility model, the intelligent distribution box is first deployed to the construction site, the corresponding main cable is connected to the power inlet, and each intelligent distribution box is assigned a fixed digital address.
[0037] Install the terminal controller at the entrance of the construction site, connect the power supply, turn on the control terminal, and set the power statistics and on / off time period control parameters on the control terminal.
[0038] The digital address of the distribution box deployed on site is input into the control terminal, and the control terminal sends data instructions to the designated intelligent distribution box through the wireless network to complete the working parameter configuration. The intelligent distribution box sets its own working parameters according to the configuration parameters.
[0039] After the designated intelligent distribution box receives the data, it will feedback the status of the equipment according to the data instructions, and the intelligent distribution box will be successfully added to the control terminal platform.
[0040] Join all the smart distribution boxes deployed at the construction site in turn to complete the networking of multiple smart distribution boxes.
[0041] The control terminal collects data such as voltage, current, power, temperature, switch status, etc. of each intelligent distribution box one by one in a polling manner. The status and switch control of the specified distribution box can also be viewed through the touch screen.
[0042] The intelligent distribution box automatically enters the management state after power-on, collecting data such as the working current, temperature, and voltage of each line. When the system detects that the working current is zero or unchanged for a long time, it determines that no power supply is needed on site. In order to save power resources, the power output port of the equipment will be closed; the lighting output interface will automatically switch on and off according to the set time period.
[0043] Users can connect their own electrical equipment, such as grinders, cutting machines, etc., to the power output port according to their needs. Connect lighting equipment, such as light strips, LED bulbs, etc., to the lighting interface 4. Users can turn on the power output and the lighting interface 4 output through the control button on the key panel of the smart distribution box. The corresponding indicator lights up, indicating that the corresponding output circuit is turned on, which is no different from the use of a conventional distribution box.
[0044] In abnormal state: when the temperature inside the distribution box exceeds the set temperature, all outputs will be shut down to prevent electrical equipment from burning or people from getting electric shock. When a short circuit, leakage, or overload occurs, the control switch will automatically trip as usual, but the current sensor will be able to collect current changes and infer the fault type, and display the fault on the control terminal to help workers quickly find the cause of the fault.
[0045] The multiple intelligent distribution boxes deployed on site communicate with the control terminal through the wireless network to form a network and accept the control of the terminal controller. Users can manage the on-site distribution boxes through the intelligent distribution boxes and the control terminal, and can also query the status, power, current change and other data of each distribution box on the construction site through the control terminal.
[0046] Compared with conventional distribution boxes, the utility model adds sensor detection, logic switch control and wireless communication capabilities on the basis of the original short-circuit protection and leakage protection, and then realizes multiple functions through data collection, such as remote switch, current, voltage and power statistics, transient current recording, temperature detection, timer switch, etc. While giving the distribution box functions, the size and internal layout of the distribution box are improved, which has the advantages of small size, easy movement, dedicated interface and safe control.
[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
