If a person touches the pins at this time, they will be electrocuted, so there is a risk of electric shock from the plug.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.
[0041] In order to reduce the risk of electric shock when the device connected to the plug is a power generation device, the embodiment of the present application provides an anti-electric shock plug, and its specific structure can be seen in Figure 1 ( Figure 1 Only two pins are used as an example for display), specifically including: a plug body 10, a detection device 20 and at least two pins 30; the connection relationship between the components is specifically described as follows:
[0042] For each pin 30, one end thereof is encapsulated inside the plug body 10, and the other end thereof is exposed outside the plug body 10. In other words, for all the pins 30, one end of each pin 30 is encapsulated inside the plug body 10, and the other end of each pin 30 is exposed outside the plug body 10.
[0043] In actual application, for each pin 30, one end thereof encapsulated inside the plug body 10 is electrically connected to the corresponding end of the power generation device 40 to which it is connected, for transmitting electrical energy; and one end thereof exposed outside the plug body 10 is inserted into the socket 01, for achieving connectivity between the corresponding end of the power generation device 40 to which it is connected and the socket 01.
[0044] The detection device 20 is connected to the controller 50, and the detection device 20 outputs a power-off signal; the controller 50 is connected to the power generation device 40 connected to the anti-electric shock plug.
[0045] The power-off signal is a signal output by the detection device 20 when the anti-electric shock plug is not inserted into the socket 01. In other words, when the detection device 20 detects that the anti-electric shock plug is not inserted into the socket 01, the power-off signal is output.
[0046] Optionally, a power-off signal can be output when the anti-electric shock plug suddenly falls off, or when the anti-electric shock plug has not been plugged in. No specific limitation is made here, and it can be determined according to the specific situation, all of which are within the protection scope of this application.
[0047] When the controller 50 receives the power-off signal, the controller 50 controls the power generating device 40 connected to the anti-electric shock plug to stop transmitting power to the anti-electric shock plug.
[0048] In addition, the power-off signal indicates that the anti-electric shock plug is not inserted into the socket 01.
[0049] In actual application, when the anti-electric shock plug is not inserted into the socket 01 , the controller 50 controls the power generation device 40 connected to the anti-electric shock plug to stop transmitting power to the anti-electric shock plug.
[0050] It should be noted that how the detection device 20 detects whether the anti-electric shock plug is not inserted into the socket 01 will be described in detail below and will not be repeated here.
[0051] In a specific example, if Figure 1 As shown, the detection device 20 is arranged inside the plug body 10 .
[0052] In another specific example, the detection device 20 is disposed on the surface of the plug body 10 .
[0053] The above examples only show two configuration methods of the detection device 20. In practical applications, including but not limited to these, no specific limitation is made here and it can be determined according to the specific situation, all of which are within the scope of protection of this application.
[0054] In a specific example, the connection between the detection device 20 and the controller 50 , and the connection between the anti-electric shock plug and the power generation device 40 share a common cable.
[0055] The connection between the electric shock protection plug and the power generation device 40 refers to the connection between each pin 30 and the power generation device 40 .
[0056] In another specific example, the connection between the detection device 20 and the controller 50 , and the connection between the anti-electric shock plug and the power generation device 40 , respectively use independent cables.
[0057] Since the method shown in the first example above can save cables, that is, can save costs, the cable shown in the first example is taken as a preferred implementation.
[0058] The above two examples only show two ways of using cables with different connections. No specific limitation is made here and the methods may be determined according to the specific circumstances and are all within the scope of protection of this application.
[0059] In the anti-electric shock plug, when the anti-electric shock plug is not inserted into the socket 01, the detection device 20 outputs a power-off signal to the controller 50. Since the power-off signal indicates that the anti-electric shock plug is not inserted into the socket, the controller 50 will control the above-mentioned power generation equipment 40 to stop supplying power to the anti-electric shock plug. Therefore, the pin 30 of the anti-electric shock plug is no longer energized. Therefore, the anti-electric shock plug provided in the present application can reduce the risk of electric shock of the plug when the device connected to the plug is a power generation equipment 40.
[0060] Another embodiment of the present application also provides an implementation of the detection device 20, and its specific structure can be seen in Figure 2 ( Figure 2 exist Figure 1 Based on the above, only one detection switch S is used as an example for demonstration), which specifically includes: at least one detection switch S; the connection relationship between the components is specifically described as follows:
[0061] For each detection switch S, two ends thereof are respectively connected to two interfaces of the input end of the controller 50, and the detection switch S includes two states.
[0062] For each detection switch S, its first state is the state in which the anti-electric shock plug is inserted into the socket 01 ; its second state is the state in which the anti-electric shock plug is not inserted into the socket 01 .
[0063] In a specific example, for each detection switch S, its first state is a normally open state, and its second state is a normally closed state, that is: when the anti-electric shock plug is not inserted into the socket 01, the detection switch S is in a normally closed state, and when the anti-electric shock plug is inserted into the socket 01, the detection switch S is in a normally open state.
[0064] In another specific example, for each detection switch S, its first state is a normally closed state, and its second state is a normally open state; that is, when the anti-electric shock plug is not inserted into the socket 01, the detection switch S is in a normally open state, and when the anti-electric shock plug is inserted into the socket 01, the detection switch S is in a normally closed state.
[0065] The above two examples only show two implementation methods of detecting the state of the switch S. In practical applications, including but not limited to these, no specific limitation is made here and it may be determined according to the specific circumstances, all of which are within the scope of protection of this application.
[0066] In a specific example, for each detection switch S, the detection switch S may be a switch whose state changes due to a change in position.
[0067] Optionally, for each detection switch S, the detection switch S can be a limit switch, a button switch, or a proximity switch. In practical applications, this includes but is not limited to these. No specific limitations are made here and it may depend on the specific circumstances. All are within the scope of protection of this application.
[0068] In a specific example, the detection switch S is disposed on a non-metallic part of the plug; for example, Figure 2 As shown, the electric shock protection plug includes two pins 30 , and the detection device 20 includes a detection switch S, which is arranged at an empty space on one side of one pin 30 .
[0069] The above example only shows one setting method of the detection switch S. In practical applications, including but not limited to this, no specific limitation is made here and it can be determined according to the specific situation, all of which are within the scope of protection of this application.
[0070] The above is only one implementation of the detection device 20. In practical applications, including but not limited to this, no specific limitation is made here and it can be determined according to the specific situation, all of which are within the protection scope of this application.
[0071] Another embodiment of the present application provides a power generation system, whose specific structure is as follows: Figure 2 As shown, it specifically includes: a power generation device 40, a controller 50 and an anti-electric shock plug as provided in the above embodiment; the connection relationship between the various components is specifically described as follows:
[0072] The power generation device 40 is connected to the controller 50; the power generation device 40 is connected to the anti-electric shock plug.
[0073] Optionally, the controller may be independently provided or may be provided in the power generation device 40, which is not specifically limited here and may be determined according to specific circumstances, all of which are within the protection scope of the present application.
[0074] It should be noted that the specific connection relationship between the power generation device 40 and the anti-electric shock plug has been described in detail in the above embodiment and will not be repeated here.
[0075] In a specific example, the power generation equipment 40 may be at least one of the following: photovoltaic power generation equipment, wind power generation equipment, diesel power generation equipment, fuel cell equipment, or energy storage equipment.
[0076] The above examples only illustrate various implementations of the power generation device 40. In practical applications, including but not limited to these, no specific limitations are made here and may be determined according to specific circumstances, all of which are within the scope of protection of this application.
[0077] This embodiment also provides a specific implementation of the power generation device 40, and its specific structure can be seen in Figure 3 ( Figure 3 Only in Figure 2Based on the example of the power generation equipment including both the power electronic switch 42 and the grid-connected switch 43, it is specifically shown that: the power generation source 41, and the power electronic switch 42 and / or the grid-connected switch 43; the connection relationship between the various devices is specifically described as follows:
[0078] The poles of the output end of the generator 41 are respectively connected to the pins 30 in the anti-electric shock plug in a one-to-one correspondence; the power electronic switch 42 is connected in series between the output end of the generator 41 and the anti-electric shock plug; the grid-connected switch 43 is connected in series between the output end of the generator 41 and the anti-electric shock plug; the generator 41, the power electronic switch 42 and the grid-connected switch 43 are all controlled by the controller 50.
[0079] When the controller 50 receives a power-off signal, if the power generation equipment 40 only includes a power electronic switch, the power electronic switch 42 is controlled to be disconnected; if the power generation equipment 40 only includes a grid-connected switch 43, the grid-connected switch 43 is controlled to be disconnected; if the power generation equipment 40 includes a power electronic switch 42 and a grid-connected switch 43, at least one of the power electronic switch 42 and the grid-connected switch 43 is controlled to be disconnected.
[0080] In a specific example, see Figure 4 ( Figure 4 Only in Figure 3 The controller 50 includes: a control module 51 and a digital quantity detection circuit 52, the input end of the control module 51 is connected to the output end of the digital quantity detection circuit 52, and the input end of the digital quantity detection circuit 52 is connected to the detection device 20 in the anti-electric shock plug.
[0081] The digital quantity detection circuit 52 is used to determine whether the received signal is a power-off signal; for example, the first state of the detection switch S is a normally open state and the second state is a normally closed state. When the digital quantity detection circuit 52 detects that the detection switch S is in the second state, it notifies the control module 51 that a power-off signal has been received.
[0082] The above example only shows one implementation of the controller 50. In practical applications, including but not limited to this, no specific limitation is made here and it may be determined according to the specific circumstances, all of which are within the scope of protection of this application.
[0083] The above is only one implementation of the power generation device 40. In practical applications, including but not limited to this, no specific limitation is made here and it may be determined according to the specific situation, all of which are within the protection scope of this application.
