Description

Technical Field

[0001] This application relates to the field of electricity, specifically to socket technology. Background Art

[0002] The imbalance of power grid load over time is a major problem faced by the current power system.

[0003] To encourage staggering electricity usage times, the power grid system has introduced a time-of-use electricity price plan. By setting peak electricity prices and off-peak electricity prices, it guides electrical equipment to flexibly use electricity during periods with sufficient power supply.

[0004] However, some people are not sensitive to electricity prices. Therefore, the time-of-use electricity price plan has little effect on this part of the population.

[0005] Therefore, there is a need for an electricity usage technical solution that does not require users to actively intervene, can finely balance peaks and valleys in a timely manner for different areas and different minute time periods, and can also be controlled to turn on by a network.

[0006] And the socket is one of the most commonly used devices that electrical equipment can hardly do without. Therefore, changing the electricity usage time of the electrical equipment plugged into the socket by modifying the socket has become an urgent electrical technology problem to be solved. Utility Model Content

[0007] The purpose of this utility model is to provide an intelligent socket with intelligent power grid access function to solve at least one of the above technical problems.

[0008] The technical problems solved by this utility model can be realized by the following technical solutions:

[0009] An intelligent socket with intelligent power grid access function includes a socket connected to the mains interface. The socket has a housing and a panel, and socket jacks are arranged on the panel.

[0010] It also includes a power supply part, which is connected to the mains interface;

[0011] It further includes a timing switch system with at least one timing-on period. The timing switch system has a control system and a switching element;

[0012] The control system has a parameter input end for receiving parameter settings and a switch control output end for controlling the opening and closing of the switching element;

[0013] The switching element has a controlled input end that is controlled to be turned on;

[0014] The switch control output end of the control system is signal-connected to the controlled input end of the switching element;

[0015] The power supply part is power-supplied and connected to the control system;

[0016] The mains power interface is connected to the socket outlet through a switching element;

[0017] The timing switch system adopts a timing switch system with network control function. The timing switch system with network control function is provided with a network signal input terminal for setting the timing-on period;

[0018] The timing switch system is also provided with a manual input component for setting the timing-on period.

[0019] In the above design, a timing switch system is set on the socket. The on-period of the timing switch system is delayed to the low grid valley time period through the control system, so that the electrical equipment plugged into the socket can obtain mains power during the low grid valley time period. The beneficial effects of such a design are as follows. On the one hand, it can save the electricity cost because the electricity price in the low valley stage is cheaper than that in the peak stage. On the other hand, running the electrical equipment during the low electricity consumption period can balance the load of the power grid.

[0020] Furthermore, the manual input component includes a touch key device with at least two touch keys for increasing and decreasing numbers. The touch key device includes a digital output interface with BCD coding, and the digital output interface is signal-connected to the parameter input terminal of the control system.

[0021] The function of the touch key device is to manually set the operation time period of the timing switch system. By setting the operation time period to the low valley period, it can not only save the electricity cost but also help balance the idle load of the power grid.

[0022] For further optimization, a movable partition is also provided behind the socket outlet. Through holes corresponding to the socket outlet are provided on the partition. Under the action of its own weight or elastic parts, the through holes and the socket outlet are misaligned;

[0023] An electromagnetic telescopic rod is also provided in the housing. The electromagnetic telescopic rod is connected to the partition, and under the action of the electromagnetic telescopic rod, the through hole and the socket outlet are communicated;

[0024] A circuit board is also provided in the housing. The circuit board is provided with two switch position input terminals and one signal position output terminal. The two touch keys are respectively connected to the switch position input terminals of the circuit board, and the signal position output terminal of the circuit board is controllably connected to the electromagnetic telescopic rod.

[0025] In the above design, a partition for forming misaligned jacks is added behind the panel. Due to the existence of the misaligned through holes on the partition, if the socket is inserted wrongly, the misalignment will block the access to the mains power inside the socket, which can play a role in safety protection.

[0026] When an electrical device needs to be plugged into the socket, pressing two touch buttons simultaneously can trigger the electromagnetic telescopic rod to start and move the partition, so that the through hole and the socket outlet are directly connected, and the electrical plug of the electrical device can be inserted into the socket to make contact with the mains electricity.

[0027] Furthermore, the manual input component further includes a manual switch. One end of the manual switch is connected to the power supply part, and the other end is connected to the controlled input end of the switching element.

[0028] The beneficial effect of retaining the manual switch is that if the timing switch system has set the opening period, but it has not reached the opening period yet, and there is an urgent matter that needs to be started immediately, such as getting the news that the power grid is about to be maintained. At this time, it is necessary to run the electrical device immediately, and the manual switch can be used to handle this scenario. When the manual switch is pressed, the switching element is turned on, and the electrical device is immediately turned on.

[0029] Furthermore, the socket further includes a Wi-Fi connected networking module. The networking module is provided with a control signal output end, and the control signal output end is connected to the network signal input end of the timing switch system.

[0030] In the above design, a Wi-Fi connected networking module is provided in the socket. The networking module can receive an opening instruction for the socket from the network, such as remotely controlling the socket through a mobile phone APP.

[0031] For further expansion, the socket can be plugged into a charging pile system. The charging pile system includes a voltage conversion and rectification device that converts mains electricity into direct current, and also includes a charging control module. The charging control module is a control device that regulates the direct current. The regulated direct current is transmitted to the electric vehicle through the charging socket;

[0032] The charging control module is also provided with an input interface for setting the charging completion time limit, and a manual setting device adapted to the input interface;

[0033] The networking module also has a parameter output interface for remotely setting the charging completion time limit, and the parameter output interface is connected to the input interface of the charging control module.

[0034] In the above design, the socket can control the charging pile system to start during the low valley period, and the charging control module can adjust the starting power according to the starting time and the charging completion time limit to balance the power grid.

[0035] Grid balance means that the supply-demand relationship of the power grid approaches a stable state, that is, the power generation and power consumption in the power system are roughly equal, or the system can quickly respond to any minor supply-demand mismatch to ensure the stable operation of the power system. When the power grid tends to be balanced, it can guarantee the continuity, reliability and safety of power supply, so as to meet the electricity demand of users.

[0036] An electricity consumption scenario involves a charging pile system for charging an electric vehicle. The electric vehicle is connected to the charging pile system at 6 p.m. Without the intervention of a timing switch system, the charging pile system starts charging immediately after being plugged in until it is fully charged. At this time, it is still during the peak period, and nearly 6 hours are using peak electricity prices. Since it takes approximately 8 hours to fully charge an electric vehicle, the time using off-peak electricity prices is less than 2 hours. Nearly 75% of the time occupies peak electricity consumption and pays peak electricity prices.

[0037] When the timing switch system of the socket intervenes in the charging pile system, it can avoid peak periods and start charging during off-peak periods. Therefore, low-cost off-peak electricity can be used throughout the process, which not only saves electricity costs but also greatly improves the smoothness of the power grid supply.

[0038] In another electricity consumption scenario, when the power grid issues a maintenance notice, the socket can be remotely controlled through a mobile APP to avoid losses caused by the power grid maintenance time. Before the expected power grid maintenance time, remotely start the charging pile to complete the charging of the electric vehicle before the power grid maintenance time.

[0039] Furthermore, the socket can be plugged into a refrigerator. The refrigerator includes a temperature control system and a compressor. The temperature control system has a temperature input interface for receiving temperature settings; the networking module also has a parameter output interface for remotely setting the temperature, and the parameter output interface is connected to the temperature input interface.

[0040] In the above design, in the extended electricity consumption scenario where the socket is connected to the Wi-Fi networking module, when the power grid issues a maintenance notice, through the Wi-Fi networking module, the socket can remotely receive control instructions sent by the mobile APP to avoid losses caused by power grid maintenance:

[0041] If the electrical device is a refrigerator, before the expected power grid maintenance time, use the mobile APP to start the refrigerator, perform a forced cooling on the freezing area once, and then let the compressor enter the sleep state to avoid the reverse current generated by the inductance effect of the compressor from damaging the refrigerator itself or even impacting the power grid.

[0042] If the electrical device is an air conditioning system, before the expected power grid maintenance time, use the mobile APP to start the air conditioner. For the heating function, increase the heating temperature; for the cooling function, lower the cooling temperature. Then, before the power grid maintenance time, let the compressor enter the sleep state in advance to avoid the reverse current generated by the inductance effect of the compressor from damaging the air conditioning system or even impacting the power grid.

[0043] If the electrical device is a fish pond oxygenation system, before the expected power grid maintenance time, use the mobile APP to start the oxygenator and perform a strong oxygen supply to the fish pond to prevent the fish population from dying due to lack of oxygen.

[0044] Furthermore, the switching element uses an Insulated Gate Bipolar Transistor (IGBT) G4PH50UD.

[0045] An Insulated Gate Bipolar Transistor (IGBT) is a semiconductor device that can withstand high voltages and high currents, especially with a switching speed reaching the microsecond level.

[0046] The maximum voltage withstand of G4PH50UD is 1500V, and the maximum current can reach 40A, which can meet the power consumption requirements of the above-mentioned charging piles, refrigerators, air conditioners and other devices.

[0047] The socket of the present utility model delays the running time of the electrical equipment inserted into the socket to the low grid valley time period set in advance through the timing switch system. Its beneficial effects are as follows: on the one hand, the electricity price in the low valley stage is cheap, which can save the electricity cost; on the other hand, running the electrical equipment during the low electricity consumption valley period can balance the load of the power grid and is beneficial to the stable operation of the power system.

[0066] In this embodiment, a timing switch system is provided on the socket, and the opening period of the timing switch system is delayed to the grid low valley time period through the control system 4, so that the electrical equipment plugged into the socket can obtain the mains power during the grid low valley time period. The beneficial effect of such a design is that, on the one hand, the electricity cost can be saved because the electricity price in the low valley stage is cheaper than that in the peak stage; on the other hand, operating the electrical equipment during the low electricity consumption valley period can balance the load of the power grid.

[0067] Embodiment 1:

[0069] In this embodiment, the function of the touch button device 3 is to manually set the operation time period of the timing switch system. By setting the operation time period to the low valley period, both the electricity cost can be saved and the idle load of the power grid can be balanced.

[0070] Referring to Figure 3 As shown, a movable partition 10 is further provided behind the socket jack 7. The partition 10 is provided with through holes corresponding to the socket jack 7.

[0073] In this embodiment, a partition 10 for forming misaligned jacks is added behind the socket jack 7 on the panel 9. Due to the existence of the misaligned through holes on the partition 10, if the jack is misinserted, the misalignment will block the access to the mains power inside the socket, which can play a role in safety protection.

[0074] When the electrical equipment needs to be plugged into the socket, the two touch buttons are pressed simultaneously, which can trigger the electromagnetic telescopic rod to start and move the partition 10, so that the through holes and the socket jack 7 are directly connected, and the electrical plug of the electrical equipment can be inserted into the socket to contact the mains power.

[0077] In this embodiment, the beneficial effect of retaining the manual switch 6 is that if the timing switch system has set the opening period, but it has not reached the opening period yet, and there is an urgent matter that needs to be started immediately, such as getting the news that the power grid is about to be maintained. At this time, it is necessary to immediately operate the electrical equipment, and the manual switch 6 can be used to handle this scenario. When the manual switch 6 is pressed, the switching element 5 is turned on, and the electrical equipment is immediately turned on.

[0078] Embodiment 3:

[0079] The socket further includes a Wi-Fi connected networking module. The networking module is provided with a control signal output end, and the control signal output end is connected to the network signal input end of the timing switch system.

[0080] In this embodiment, a Wi-Fi connected networking module is provided in the socket. The networking module can receive the opening instruction for the socket from the network, such as remotely controlling the socket through a mobile phone APP.

[0081] Further expanded, the socket can be plugged into a charging pile system. The charging pile system includes a step-down and rectifying device that converts commercial power into direct current, and also includes a charging control module. The charging control module is a control device that regulates the direct current. The regulated direct current is transmitted to the electric vehicle through the charging socket;

[0082] The charging control module is further provided with an input interface for setting the charging completion time limit, and a manual setting device adapted to the input interface;

[0083] The networking module also has a parameter output interface for remotely setting the charging completion time limit, and the parameter output interface is connected to the input interface of the charging control module.

[0084] In this embodiment, the socket can control the charging pile system to start during the low valley period, and the charging control module can adjust the starting power according to the starting time and the charging completion time limit to balance the power grid.

[0085] Grid balance means that the supply-demand relationship of the power grid approaches a stable state, that is, the power generation and power consumption in the power system are roughly equal, or the system can quickly respond to any minor supply-demand mismatch to ensure the stable operation of the power system. When the power grid tends to be balanced, it can ensure the continuity, reliability and safety of power supply, so as to meet the power consumption needs of users.

[0086] An electricity consumption scenario involves a charging pile system for charging an electric vehicle. The electric vehicle is connected to the charging pile system at 6 p.m. Without the intervention of a timing switch system, the charging pile system starts charging immediately after being plugged in until it is fully charged. At this time, it is still during the peak period, and there are nearly 6 hours of peak electricity prices being used. Since it takes approximately 8 hours to fully charge an electric vehicle, the time using off-peak electricity prices is less than 2 hours. Nearly 75% of the time, peak electricity is consumed and peak electricity prices are paid.

[0087] When the timing switch system of the socket intervenes in the charging pile system, it can avoid peak hours and start charging during off-peak hours. Therefore, low-cost off-peak electricity can be used throughout the process, which not only saves electricity costs but also greatly improves the smoothness of the power grid's power supply.

[0090] In this embodiment, in the extended electricity consumption scenario where the socket is connected to the Wi-Fi networking module, when the power grid issues a maintenance notice, through the Wi-Fi networking module, the socket can remotely receive control instructions sent by the mobile phone APP to avoid losses caused by power grid maintenance:

[0091] If the electrical appliance is a refrigerator, the refrigerator can be started with the mobile phone APP before the expected power grid maintenance time to perform a forced cooling of the freezing area once, and then let the compressor enter the sleep state to avoid the reverse current generated by the inductance effect of the compressor from damaging the refrigerator itself or even impacting the power grid.

[0092] If the electrical appliance is an air conditioning system, the air conditioner can be started with the mobile phone APP before the expected power grid maintenance time. For the heating function, increase the heating temperature; for the cooling function, lower the cooling temperature. Then, before the power grid maintenance time, let the compressor enter the sleep state in advance to avoid the reverse current generated by the inductance effect of the compressor from damaging the air conditioning system or even impacting the power grid.
