DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1, reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, provides a photovoltaic inverter safety test platform, which can realize the effect of automatically plugging and unplugging multiple test plugs 107 to improve the test efficiency, and includes a test component 100, including a support platform 101, a DC motor group 102 arranged on the left side of the support platform 101, an AC motor group 103 arranged on the right side of the support platform 101, an inverter body 104 arranged on the support platform 101, a plurality of female plugs 105 arranged on the inverter body 104, a plurality of wires 106 arranged on the DC motor group 102 and the AC motor group 103, and a plurality of wires 106 arranged on the plurality of wires 106. Test plug 107; plug-in component 200, including a positioning component 201 arranged on the support platform 101, a lifting component 202 arranged on the positioning component 201, a moving component 203 arranged on the positioning component 201, an adjusting component 204 arranged on the moving component 203, a locking component 205 arranged on the adjusting component 204, and an identification component 206 arranged on the moving component 203; a closing component 300, including a pushing component 301 arranged on the moving component 203, a guiding component 302 arranged on the pushing component 301, and a closing component 303 arranged on the moving component 203.

[0030] Specifically, the DC motor group 102 here can be connected to the solar panel, or directly simulate the DC power generated by the solar panel, and the AC motor group 103 can store and transmit AC power. The DC motor group 102 and the AC motor group 103 here are both existing technologies and will not be elaborated here. When in use, the test plug 107 of the wire 106 on the DC motor group 102 and the AC motor group 103 is simultaneously connected to the female plug 105 on the inverter body 104. It should be noted that the test plug 107 here is different from the male plug in that there is no shrapnel on the test plug 107 here, and the phenomenon that the test plug 107 cannot be separated from the female plug 105 will not occur.

[0031] Furthermore, the positioning assembly 201 includes a base plate 201a arranged on the support platform 101, two L-shaped plates 201b are arranged on the base plate 201a, side walls of the two L-shaped plates 201b are fixedly connected with side plates 201c, wing plates 201d are fixedly connected to the side plates 201c, two first electric slide rails 201e are arranged on the support platform 101, and the first electric slide rails 201e are slidably connected with a first slider 201f fixed to the L-shaped plate 201b; the lifting assembly 202 includes an installation groove 202a arranged on the support platform 101, the upper end and the right end of the installation groove 202a are open, the inner wall of the installation groove 202a is fixedly connected with a cylinder 202b, and the telescopic end of the cylinder 202b is fixedly connected to the base plate 201a.

[0032] Among them, the length of the bottom plate 201a here is smaller than the width of the opening 203d, so that a small part of the inverter body 104 extends to the outside of the bottom plate 201a, which is convenient for the test plug 107 to dock with the female plug 105 after the bottom plate 201a is raised or lowered. The bottom plate 201a here can be raised or lowered, so that the height of the female plug 105 can be adjusted, which is convenient for the test plug 107 to face the female plug 105.

[0033] Preferably, the moving assembly 203 includes a second electric slide rail 203a disposed on the support platform 101, a second slider 203b is slidably connected to the second electric slide rail 203a, a mounting plate 203c is fixedly connected to the second slider 203b, a plurality of openings 203d are provided on the mounting plate 203c, a plurality of test plugs 107 are all located in the openings 203d, a ring 203e is fixedly connected to the openings 203d, and the wire 106 passes through the ring 203e; the adjusting assembly 204 includes a fixed A push rod 204a is connected to the test plug 107, and a circular opening is provided on the circular ring 203e for the push rod 204a to pass through, and a push ring 204b is fixedly connected to the push rod 204a; the clamping assembly 205 includes a plurality of mounting tubes 205a with open ends rotatably connected to the mounting plate 203c, a transverse groove 205b is provided on the inner wall of the mounting tube 205a, and an arc groove 205c is connected to the transverse groove 205b, and a clamping block 205d that cooperates with the transverse groove 205b is fixedly connected to the push rod 204a.

[0034] It should be noted that the first electric slide rail 201e and the second electric slide rail 203a are perpendicular to each other. The thickness of the mounting plate 203c is greater than the length of the test plug 107, so that the test plug 107 can be completely placed in the opening 203d. The inner circle of the ring 203e is greater than the diameter of the wire 106, so that the wire 106 will not be unable to pass through the ring 203e. When the block 205d is facing the horizontal groove 205b, the push rod 204a can slide left and right without restriction.

[0035] When in use, firstly, the inverter body 104 is placed on the two L-shaped plates 201b. When the inverter body 104 is placed on the L-shaped plates 201b, the side walls of the inverter body 104 are abutted against the vertical sides of the L-shaped plates 201b. The arrangement of the wing plates 201d here can guide the inverter body 104 when the inverter body 104 is placed on the L-shaped plates 201b. When the inverter body 104 is placed on the L-shaped plates 201b, the first electric slide rail 201e is started, so that the two first slide plates move toward the middle, thereby the two L-shaped plates 201b move toward the middle, so that the two side plates 201c move toward the middle, and the inverter body 104 is clamped between the two side plates 201c. At the same time, the vertical side wall of the L-shaped plate 201b is against the front end of the inverter. Then, according to the model of the inverter body 104, the required test plug 107 is selected. When pushing out the test plug 107, it is only necessary to press the ring 203e to make the ring 203e move toward the mounting plate 203c. At this time, the push rod 204a pushes the test plug 107 to move, so that the test plug 107 is pushed out of the opening 203d. When the push rod 204a moves, the block 205d moves. At this time, the horizontal groove 205b is opposite to the block 205d, and the movement of the block 205d is not affected. When the test plug 107 is completely pushed out, the block 205d enters the arc groove 205c. At this time, the mounting cylinder 205 is rotated. a, so that the transverse groove 205b and the block 205d are misaligned, the block 205d can be prevented from automatically resetting, and the push rod 204a can be prevented from automatically resetting, ensuring that the test plug 107 is outside the opening 203d (there is friction between the block 205d and the inner wall of the arc groove 205c here, thereby preventing the block 205d from sliding by itself and ensuring the stability of the block 205d). After all the required test plugs 107 are pushed out, if the test plug 107 and the female plug 105 still do not correspond, the cylinder 202b is started to lift the bottom plate 201a, driving the inverter body 104 to lift, thereby adjusting the height of the inverter body 104 and the height of the female plug 105. After the test plug 107 is aligned with the female plug 105, the second electric slide rail 203a is started to make the second slider 203b move toward the inverter body 104. At this time, the mounting plate 203c moves toward the inverter body 104, so that the test plug 107 is plugged into the female plug 105. At this time, the DC motor group 102 and the AC motor group 103 are started to test the inverter body 104. When the test shows normal, it means that there is no short circuit or false connection, indicating that the inverter is safe. Then the second electric slide rail 203a is started to reset the second slider 203b, driving the mounting plate 203c to reset, thereby resetting multiple test plugs 107 and completing the safety test of a single inverter body 104.

[0036] In summary, by setting the timing component and the plug-in component 200, when the internal short circuit and false connection of the inverter body 104 are carried out, multiple test plugs 107 can be automatically plugged in and out, without the need to manually plug multiple test plugs 107, thus avoiding the worker's hand pain from pressing the spring piece, and simultaneously plugging and unplugging multiple test plugs 107 increases the testing time.

[0037] Example 2, reference Figure 1 to Figure 4 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an identification component 206 of a photovoltaic inverter safety test platform, which solves the problem of how to correctly select a test plug 107 according to different models of inverter bodies 104. It includes an identification component 206, including multiple frame selection areas 206a arranged on a mounting plate 203c, the multiple frame selection areas 206a divide the multiple openings 203d into multiple areas, the edges of the multiple frame selection areas 206a are provided with grooves 206b, and the multiple grooves 206b are filled with fluorescent layers 206c of different colors. An identification plate 206d is provided in the frame selection area 206a, where the identification plate 206d displays the model. According to the cooperation between the identification plate 206d and the frame selection area 206a, the area where the test plug 107 needs to be pushed out can be correctly selected, making it easier to use (here it means that there is no need to specifically find the corresponding wire 106, and the test plug 107 can be quickly pushed out).

[0038] During use, when the test plug 107 needs to be pushed out, first observe the identification plate 206d to find the area corresponding to the model of the inverter body 104, and then push out the test plug 107 in the area corresponding to the identification plate 206d. The setting of the fluorescent layer 206c here facilitates the distinction of the area boundaries, and when there is an intersection between the areas, the test plug 107 in the corresponding area can also be accurately found.

[0039] In summary, by setting the identification component 206, when pushing out the test plug 107, you only need to find the identification plate 206d corresponding to the inverter body 104 model, and then push out the test plug 107 in the area corresponding to the identification plate 206d, so that the test plug 107 can be correctly pushed out, making the operation simpler.

[0040] Example 3, reference Figures 1 to 10, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a closed component 300 of a photovoltaic inverter safety test platform, which solves the problem of how to prevent dust from entering the unused test plug 107 and affecting subsequent detection. It includes a pushing component 301, including a plurality of supporting cavities 301a arranged on the mounting plate 203c, a sliding rod 301b is slidably connected in the supporting cavity 301a, the sliding rod 301b penetrates the supporting cavity 301a and is fixedly connected to the push ring 204b, and a guide component 302 includes a rotating drum 302a rotatably connected to the inner wall of the supporting cavity 301a, and a threaded groove 302b is provided on the inner wall of the rotating drum 302a. The left and right ends of the groove 302b are connected with straight grooves 302c, and the straight groove 302c at the right end passes through the rotating cylinder 302a. The slide rod 301b is fixedly connected with a guide ball 302d that cooperates with the straight groove 302c and the threaded groove 302b; the closing component 303 includes a gear 303a fixedly connected to the side wall of the rotating cylinder 302a, and the mounting plate 203c is provided with a plurality of expansion grooves 303b connected with the opening 203d, and two closing plates 303c are slidably connected in the expansion grooves 303b, and the closing plate 303c is fixedly connected with an L-shaped bar 303d, and the L-shaped bar 303d is fixedly connected with a tooth plate 303e that meshes with the gear 303a.

[0041] Specifically, the distance between the expansion slot 303b and the ring 203e is greater than the length of the test plug 107, so that there is a gap between the expansion slot 303b and the test plug 107, ensuring that there is enough distance for the closing plate 303c to be stuck, thereby avoiding collision between the test plug 107 and the closing plate 303c. Here, the two tooth plates 303e are respectively located at the upper and lower ends of the gear 303a, so that when the gear 303a rotates, the two tooth plates 303e move in opposite directions (that is, the two closing plates 303c move toward the middle or to both sides at the same time).

[0042] It should be explained that when the test plug 107 is not in use (especially when testing a batch of inverters, which may take several days), dust will inevitably enter the opening 203d. After the dust enters the opening 203d, it is easy for the dust to enter the test plug 107, which may easily cause static dust and affect the test results.

[0043] When in use, first, the test plug 107 is placed in the opening 203d, and the two closing plates 303c are fitted together to close the opening 203d. At this time, the test plug 107 can be dustproof. An elastic plug can be provided on the inner wall of the ring 203e to prevent dust from entering through the gap between the ring 203e and the wire 106. When the ring 203e is pushed, the push rod 204a moves, and at the same time, the slide bar 301b is driven to move. When the slide bar 301b moves, the guide ball 302d on the slide bar 301b moves from the straight groove 302c to the threaded groove 302b. When the guide ball 302d moves to the threaded groove 302e, 02b, there is still a gap between the test plug 107 and the closing plate 303c, and then with the movement of the slide bar 301b, the guide ball 302d cooperates with the threaded groove 302b to drive the rotating drum 302a to rotate, so that the gear 303a rotates, driving the two toothed plates 303e to move to both ends, thereby driving the two closing plates 303c to open, and the test plug 107 can move to the outside of the opening 203d. When the opening 203d is opened, the guide ball 302d moves into the straight groove 302c, and the rotating drum 302a does not rotate, so that the gear 303a and the toothed plate 303e will not be de-toothed.

[0044] In summary, by setting up a closing component, when the test plug 107 is not in use, the closing plate 303c closes the opening 203d to prevent dust from entering the test plug 107. During testing, only the ring 203e needs to be pushed to open the opening 203d first and then the test plug 107, thereby protecting the test plug 107 and facilitating use.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
