Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0035] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0036] In the related art, when photovoltaic modules are installed on site, it is only necessary to build a mounting frame on site, then fix the photovoltaic modules on the mounting frame, and then reasonably arrange the lines of the photovoltaic modules and some electronic devices so that the generated electricity can be stored or transported out in time.

[0037] However, when there is a large current during a thunderstorm or due to a short circuit in the photovoltaic module circuit, it is easy to cause the diodes in a series of electronic devices to break down, making the electronic devices unable to be used normally afterwards. In serious cases, the fault point cannot be removed in time, and discharge continues in the circuit, which may cause a fire and cause further losses.

[0038] Therefore, the embodiment of the present application provides a circuit fuse device, which is connected to the circuit of the photovoltaic module through a connecting line by setting a protective part and a fuse inside the protective part; when a large current appears in thunderstorm weather or the photovoltaic module circuit is short-circuited, the fuse will fuse before the electronic device is damaged, so that the photovoltaic module circuit is in an open circuit state, thereby having a better protection effect on the circuit and reducing the possibility of damage to the electronic device; and, during subsequent maintenance, it is only necessary to check the location of the fuse and replace the fuse to promptly eliminate the fault point and restore the normal operation of the photovoltaic module; at the same time, the protective part has a better protective effect on the fuse, which can reduce the possibility of the fuse being affected by external force or moisture during use, improve the safety of the use of the fuse, extend the service life, and solve the problem of poor use effect of the photovoltaic module circuit in the prior art.

[0039] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0040] An embodiment of the present application provides a line protection device.

[0041] Embodiment 1:

[0042] like Figure 1 As shown, a line safety device includes a safety component 100, a protective component 200 and a connecting component 300; the protective component 200 has an installation cavity, the safety component 100 is detachably arranged inside the installation cavity, and the protective component 200 is used to protect the safety component 100; the connecting component 300 includes at least two connecting wires 320, each connecting wire 320 is respectively connected to the two ends of the safety component 100, and the connecting wire 320 is also used to connect to the line of the equipment to connect the safety component 100 to the line.

[0043] Specifically, the safety element 100 is set as a fuse, which can be in the shape of a wire, a sheet, a tube or other shapes, and there is no limitation on this; the safety element 100 can be made of a lead-antimony alloy or a lead-tin alloy. The safety element 100 is set in the installation cavity of the protective element 200, so that the protective element 200 has a better protective effect on the safety element 100.

[0044] In addition, in the embodiment of the present application, the connecting wire 320 is specifically configured as two, and the two connecting wires are respectively connected to the two ends of the safety component 100, and the end of the connecting wire 320 away from the safety component 100 passes through the outside of the protective component 200 to be used to connect to the circuit of the photovoltaic component or other equipment, so that the safety component 100 is connected to the circuit.

[0045] In other embodiments, the number of connecting lines 320 may also be set to other numbers according to actual needs, and there is no limitation to this.

[0046] When in use, the insurance component 100 is connected to the circuit of the photovoltaic module through the connecting line 320. When there is a large current in thunderstorm weather or the photovoltaic module circuit is short-circuited, the insurance component 100 will fuse before the electronic device is damaged, so that the photovoltaic module circuit is in an open circuit state, thereby having a better protection effect on the circuit and reducing the possibility of damage to the electronic device; and, during subsequent maintenance, it is only necessary to check the location of the insurance component 100 and replace the insurance component 100 to eliminate the fault point in time and restore the normal operation of the photovoltaic module; at the same time, the protective component 200 has a better protective effect on the insurance component 100, which can reduce the possibility of the insurance component 100 being affected by external force or moisture interference during use, thereby improving the safety of the insurance component 100 and extending its service life, thereby solving the problem of poor use effect of the photovoltaic module circuit in the prior art.

[0047] Of course, this line protection device can also be used in the lines of other equipment, such as the main lines of buildings, household appliances such as air conditioners and refrigerators, and lamps such as street lamps and household electric lamps, to protect the lines of other equipment.

[0048] like Figure 1 As shown, in some embodiments, the protective member 200 includes two interconnected shells 210, the shells 210 have openings and the openings of the two shells 210 are opposite to each other, and the internal spaces of the two shells 210 together constitute an installation cavity; at least one connecting line 320 is arranged on one of the shells 210, and at least one connecting line 320 is arranged on the other shell 210, and the two ends of the safety member 100 are respectively inserted into the two shells 210 and connected to the connecting lines 320.

[0049] In the embodiment of the present application, the shell 210 is hollow inside and has an open structure at one end, so that when the two shells 210 are connected to each other, the open ends of the two shells 210 cover each other, and the internal areas of the two shells 210 together constitute the installation cavity inside the protective member 200 as a whole.

[0050] In the embodiment of the present application, two connecting wires 320 are respectively disposed on the two housings 210 and penetrate the end of the housing 210 away from the opening of the housing 210. The safety member 100 is located inside the two housings 210 at the same time, and the two ends of the safety member 100 extend into the two housings 210 respectively, and the ends of the safety member 100 are connected to the connecting wires 320.

[0051] During installation, the insurance component 100 is placed inside the two housings 210 so that the ends of the insurance component 100 face the connecting wires 320, and then the two housings 210 are covered with each other so that the two connecting wires 320 are simultaneously connected to the two ends of the insurance component 100, thereby achieving the installation of the insurance component 100. Finally, the connecting wires 320 are connected to the circuits of the photovoltaic module or other equipment, making the installation process of the insurance component 100 more convenient.

[0052] Furthermore, a partial area of ​​at least one housing 210 is configured as a transparent structure, and the area of ​​the transparent structure corresponds to the location of the safety element 100 .

[0053] In the embodiment of the present application, the sides of the two housings 210 are provided with transparent structures, so that the working condition of the safety member 100 of the housing 210 can be directly observed from the transparent area, so as to timely know whether the safety member 100 needs to be replaced; specifically, the transparent structure can be in the shape of a long strip, or can be extended along the circumference of the housing 210, or in other shapes, which are not limited to this. Of course, the transparent structure can also be provided on only one of the housings 210.

[0054] like Figure 1 As shown, in some embodiments, the connector 300 also includes a connecting base 310, which is disposed in the shell 210, and the end of the safety member 100 is detachably connected to the connecting base 310, and one end of the connecting wire 320 is connected to the connecting base 310, and the other end extends to the outside of the shell 210 and is used to connect to the circuit of the device.

[0055] In the embodiment of the present application, the connection base 310 is disposed inside the housing 210, and the connection base 310 can be fixed to the inner wall of the housing 210 by bonding, screwing, welding, clamping or other forms, without limitation. At this time, a side wall of the housing 210 is provided with an escape hole, so that the connection line 320 can pass through the escape hole, one end of the connection line 320 is located inside the housing 210 and connected to the connection base 310, and the other end extends to the outside of the housing 210.

[0056] Therefore, after the two shells 210 are covered with each other, the two ends of the safety component 100 can be detachably connected to the two connecting bases 310 respectively, and then connected to the circuit of the photovoltaic module or other equipment through the connecting line 320 to achieve the installation of the safety component 100.

[0057] like Figure 1 As shown, in some embodiments, the connection base 310 has a connection portion 311 , and the end of the safety member 100 is matched with the connection portion 311 , so that the safety member 100 can be detachably connected to the connection base 310 .

[0058] Specifically, the connecting portion 311 can be a connecting groove opened on the connecting base 310, and the groove direction of the connecting groove is consistent with the opening direction of the shell 210, so that the two ends of the safety component 100 can be respectively plugged into and matched with the connecting portions 311 on the two connecting bases 310, thereby realizing the connection between the safety component 100 and the connecting base 310, and making the installation process of the safety component 100 more convenient.

[0059] In other embodiments, the connection portion 311 may also be a clamping screw threadedly connected to one of the connection bases 310, so that one end of the safety member 100 is fastened to one of the connection bases 310 by the clamping screw, and the other end of the safety member 100 abuts against the other connection base 310. In this case, the connection base 310 without the clamping screw may also be provided with an elastic contact paddle, so that the contact paddle can elastically contact the safety member 100, while reducing the squeezing force on the safety member 100.

[0060] like Figure 1 As shown, in some embodiments, at least one connecting base 310 is provided with a movable contact 312, the connecting portion 311 is provided on the movable contact 312, the movable contact 312 is provided with a connecting rod 313, the connecting rod 313 is threadedly connected to the connecting base 310, and the length direction of the connecting rod 313 is consistent with the distribution direction of the two connecting bases 310.

[0061] In the embodiment of the present application, one of the connection bases 310 is provided with a movable contact 312 and a connection rod 313, one end of the connection rod 313 is threadedly connected to the connection base 310, and the movable contact 312 is connected to the other end of the connection rod 313. Specifically, the movable contact 312 can be fixed to the connection rod 313 by welding, screwing or other methods. At this time, the connection portion 311 on the connection base 310 is provided on the movable contact 312.

[0062] In other embodiments, both connection bases 310 may be provided with movable contacts 312 and connection rods 313 .

[0063] When in use, the connecting rod 313 can be rotated to adjust the relative position between the movable contact 312 and the connecting base 310, thereby adjusting the distance between the two connecting parts 311, thereby facilitating the installation of safety components 100 of different lengths and improving the installation effect of the safety components 100.

[0064] like Figure 1 As shown, further, in order to improve the stability of the movable contact 312 after adjustment. For example, in the embodiment of the present application, a stress spring 314 is also sleeved on the connecting rod 313, and the two ends of the stress spring 314 respectively abut the movable contact 312 and the connecting base 310. When the connecting rod 313 stays at any position, the stress spring 314 has a certain thrust on the movable contact 312 and the connecting rod 313, so that the connecting rod 313 is not easy to loosen, ensuring the stability of the safety member 100 in the connection part 311 during use.

[0065] like Figure 1 and Figure 2 As shown, in some embodiments, the protective member 200 is provided with at least one locking assembly 400, and the locking assembly 400 includes a locking member 410 and a snap-fitting portion 420, the snap-fitting portion 420 is arranged on one of the shells 210, and the locking member 410 is arranged on the other shell 210; the locking member 410 is used to cooperate with the snap-fitting portion 420 to fasten the two shells 210 together.

[0066] In the embodiment of the present application, the protective member 200 is provided with two locking assemblies 400, and the two locking assemblies 400 are respectively located on both sides of the protective member 200. The buckle portion 420 can be a block structure and fixed to the outer wall of the shell 210. The buckle portion 420 can be welded or bonded to the outer wall of the shell 210, or can be integrally formed by the shell 210, which is not limited. The locking member 410 can be a U-shaped rod structure, in which case the open end of the U-shaped rod is hinged to the outer wall of the shell 210.

[0067] During installation, the U-shaped rod can be rotated to make the movable end of the U-shaped rod buckle on the buckling portion 420 , thereby fastening the two housings 210 together to ensure the protective effect of the safety element 100 .

[0068] In other embodiments, the buckle portion 420 may also be in other shapes or be an embedding groove provided on the outer wall of the housing 210. The lock member 410 may also be a swing block integrally formed by the housing 210, the swing block can rotate relative to the housing 210, and a buckle strip is provided on the swing block, so that the buckle strip can be buckled on the buckle portion 420 by rotating the swing block, thereby realizing the buckling effect of the lock assembly 400.

[0069] like Figure 1 and Figure 3As shown, in some embodiments, a plug-in flange 211 is provided on the opening edge of one shell 210, and the plug-in flange 211 is in a closed-loop structure and is consistent with the extension direction of the opening edge of the shell 210, and a slot 212 is provided on the opening edge of the other shell 210; when the two shells 210 are connected to each other, the plug-in flange 211 is plugged into the slot 212.

[0070] After the two shells 210 are covered with each other, the opening edge of one of the shells 210 will be matched with the opening edge of the other shell 210 through the plug-in flange 211, thereby reducing the gap at the opening edges of the two shells 210, improving the sealing effect of the gap, reducing the possibility of moisture intruding into the safety component 100 through the gap, and further improving the safety of the safety component 100 during use.

[0071] In summary, Example 1 of the present application provides a circuit fuse device, in which the fuse 100 is connected to the circuit of the photovoltaic module through the connecting line 320. When there is a large current in thunderstorm weather or the photovoltaic module circuit is short-circuited, the fuse 100 will fuse before the electronic device is damaged, so that the photovoltaic module circuit is in an open circuit state, thereby having a better protection effect on the circuit and reducing the possibility of damage to the electronic device; and, during subsequent maintenance, it is only necessary to check the location of the fuse 100 and replace the fuse 100 to promptly eliminate the fault point and restore the normal operation of the photovoltaic module; at the same time, the protective member 200 has a better protective effect on the fuse 100, which can reduce the possibility of the fuse 100 being affected by external force or moisture during use, thereby improving the safety of the use of the fuse 100, extending the service life, and solving the problem of poor use effect of the photovoltaic module circuit in the prior art.

[0072] Embodiment 2:

[0073] like Figure 4 As shown, the difference between this embodiment and embodiment 1 is that the protective member 200 is configured as a protective box, the installation cavity is located in the protective box, the safety member 100 is detachably connected to the protective box, and the connecting line 320 is disposed on the protective box.

[0074] Exemplarily, the protective box includes a box body with an opening at one end and a box cover covering the box body opening, the box cover is hinged to the opening edge of the box body, and the box cover can also be slidably set on the opening edge of the box body. The protective box can also be of other shapes. The safety member 100 is detachably connected to the inner side of the box body by bolts or clips, so that the protective member 200 as a whole has a better protective effect on the safety member 100.

[0075] The connecting wire 320 connects the protection member 200 to the circuit of the photovoltaic module, and is also applicable to the circuit of other devices. One end of the connecting wire 320 is connected to the insurance member 100, and the other end passes through the outside of the protection member 200 and is connected to the circuit of the photovoltaic module.

[0076] like Figure 4 As shown, further, the protective box is provided with a data acquisition module 500 electrically connected to the safety component 100 and a display screen 600 electrically connected to the data acquisition module 500. The data acquisition module 500 is used to detect data of the circuit where the safety component 100 is located, and display the detected data through the display screen 600.

[0077] Specifically, the data acquisition module 500 can be a detection device such as a voltmeter or an ammeter, and the data acquisition module 500 is electrically connected to the circuit where the insurance part 100 is located; the display screen 600 is fixed to the outer wall of the protective part 200 by bonding, clamping, screwing, welding or other means, which is not limited. Then, the voltage, current and other parameters of the circuit where the insurance part 100 is located can be detected by the data acquisition module 500; and the detected data is displayed on the display screen 600, so that the staff can know the situation of the circuit where the insurance part 100 is located in time when on site, and then make a decision whether to replace the insurance part 100.

[0078] Of course, in order to further improve the convenience of on-site control for staff, for example, a wireless transmission module can be added to the data acquisition module 500 or the display screen 600 to facilitate remote observation or viewing of data detected on-site, further facilitating line management.

[0079] In summary, Example 2 of the present application provides a line safety device, which protects the safety component 100 inside the protection box to ensure the safety of the safety component 100 during use; in addition, the data of the line where the safety component 100 is located is detected by the data acquisition module 500, and the detected data is displayed on the display screen 600, so that the staff can know the situation of the line where the safety component 100 is located in time when they are on site.
