Description

Technical Field

[0001] The utility model belongs to the technical field of protectors, and in particular relates to an intelligent photovoltaic protector. Background Art

[0002] An intelligent photovoltaic protector is a device used to protect photovoltaic power generation systems. It can monitor and control the operating status of the system to avoid equipment damage caused by abnormal conditions such as overvoltage, overcurrent, and short circuit, thereby ensuring the safe and stable operation of the photovoltaic power generation system. However, if the protector joints are loose or the joint process is not standardized, resulting in poor contact, when current passes through these joints, it will encounter a large resistance, thereby generating heat. When this heat accumulates to a certain extent, it may cause the wire joints to burn, forming a fire source. Since multiple groups of protectors are spliced together and do not have the isolation protection of a single protector, it is easy for other protectors to spread the fire source, increase the fire, and bring huge losses. At the same time, installing the protector on the installation track is relatively cumbersome and troublesome, which reduces the effectiveness of the device.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 1 As shown:

[0024] An intelligent photovoltaic protector comprises a mounting rail 1 made of iron metal and a protector body 2 arranged on one side of the mounting rail 1.

[0025] In this embodiment: In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the protector joints are loose or the joint process is not standardized, resulting in poor contact. When current passes through these joints, it will encounter a large resistance, thereby generating heat. When this heat accumulates to a certain extent, it may cause the wire joints to burn, forming a fire source. Since multiple groups of protectors are spliced together, they do not have the isolation protection of a single protector, and it is easy to involve other protectors to cause the spread of fire, increase the fire, and bring huge losses. At the same time, the installation of the protector on the installation track is relatively cumbersome and troublesome, which reduces the use effect of the device." In terms of use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, an isolation protection component 3 is added to the present application document.

[0026] More specifically:

[0027] like Figures 1-6 As shown:

[0028] An isolation protection assembly 3 is installed on the protector body 2. The isolation protection assembly 3 includes an isolation metal cover 301 arranged on the outside of the protector body 2, a metal cover plate 302 arranged at the open end of the isolation metal cover 301, and a strong magnetic strip 1 305 fixed on both sides of the isolation metal cover 301. A strong magnetic strip 2 306 is fixed on the side of the metal cover 302 near the strong magnetic strip 1 305. A wire threading hole 1 308 and a wire threading hole 2 309 are respectively opened on the upper and lower sides of the isolation metal cover 301 near the wiring terminals of the protector body 2. A strong magnetic sheet 304 is fixed on the side of the isolation metal cover 301 near the mounting guide rail 1.

[0029] A limiting groove 303 that is compatible with the mounting guide rail 1 is provided on the side of the surface of the isolation metal cover 301 close to the strong magnetic sheet 304. The strong magnetic sheet 304 is located inside the limiting groove 303. The strong magnetic strip 1 305 and the strong magnetic strip 2 306 have opposite magnetic poles. The protector body 2 is fixed to the inside of the isolation metal cover 301 by bolts.

[0030] In this embodiment: When the intelligent photovoltaic protector is in use, the magnetism generated by the strong magnetic sheet 304 is used to adsorb the isolation metal cover 301 on the surface of the installation guide rail 1 in cooperation with the strong magnetic sheet 304, thereby completing the installation of the isolation metal cover 301, and then completing the installation of the protector body 2, improving the installation efficiency of the protector body 2, and this operation is more practical and convenient. At the same time, the setting of the limit groove 303 makes the limit groove 303 stuck on the installation guide rail 1, thereby being able to play an upper and lower limit effect on the isolation metal cover 301, avoiding falling off, and further improving the use effect of the device. The metal cover 302 is isolated from the metal cover by the strong magnetic strip 1 305 and the strong magnetic strip 2 306. 301 is connected, so as to facilitate the opening and closing operation of the metal cover 302. Multiple sets of wires are respectively passed through the wire hole 1 308 and the wire hole 2 309 according to the connection situation and connected to the terminal of the protector body 2. Then the strong magnetic strip 2 306 on the metal cover 302 is adsorbed with the strong magnetic strip 1 305 to seal the isolation metal cover 301. When the wire connector at the terminal is in poor contact and the heat generated causes combustion and a fire source, in this process, the isolation metal cover 301 and the metal cover 302 are both made of metal, thereby avoiding involvement of other protector bodies 2, avoiding the spread of the fire source, reducing losses, further improving the use effect of the device, and meeting actual use needs.

[0031] Going further;

[0032] In an optional embodiment, a plurality of heat dissipation holes 307 arranged at equal intervals are formed on both sides of the isolation metal cover 301 .

[0033] In this embodiment, heat dissipation holes 307 are provided on both sides of the isolation metal cover 301, thereby achieving a heat dissipation effect and effectively preventing overheating from affecting the normal operation of the device.

[0034] Going further;

[0035] In an optional embodiment, an L-shaped metal baffle 310 is provided on one side of the isolation metal cover 301 near the heat dissipation hole 307, and symmetrically arranged telescopic rods 311 are fixed between the L-shaped metal baffle 310 and the isolation metal cover 301. A spring 312 is wound around the surface of the telescopic rod 311, and the two ends of the spring 312 are respectively fixedly connected to the isolation metal cover 301 and the L-shaped metal baffle 310. A contact rope 316 is fixed on one side of the isolation metal cover 301 near the threading hole 1 308 and the threading hole 2 309, respectively. A symmetrically arranged top rod 313 is fixed on the surface of the L-shaped metal baffle 310, and one end of the top rod 313 conflicts with the contact rope 316. A blade 315 is fixed to the surface of the top rod 313 near the contact rope 316 through a connecting rod.

[0036] In this embodiment, when a fire source appears at a certain port of the protector body 2, one of the groups of resistance ropes 316 will be burned off, and the obstruction of the two groups of top rods 313 will be released. When the obstruction of the two groups of top rods 313 is released, the other group of resistance ropes 316 will find it difficult to support the rebound force of the spring 312 and cannot withstand the thrust of the top rod 313. At this time, the blades 315 on the other two groups of top rods 313 will contact the other group of unbroken resistance ropes 316 to cut the other group of unbroken resistance ropes 316. The two sets of resistance ropes 316 are disconnected at this time, and then the spring 312 rebounds and drives the L-shaped metal baffle 310 to move. At the same time, the setting of the telescopic rod 311 can make the L-shaped metal baffle 310 more stable during the movement. As the top rod 313 moves, the heat dissipation hole 307 is blocked, so that the isolation metal cover 301, the metal cover plate 302 and the L-shaped metal baffle 310 form a sealed space, thereby reducing air entry and achieving a rapid fire extinguishing effect.

[0037] Going further;

[0038] In an optional embodiment, a slot 314 is provided at one end of the push rod 313 near the side of the interference rope 316 , and the push rod 313 is clamped on the surface of the interference rope 316 through the slot 314 .

[0039] In this embodiment, the locking groove 314 provided on the top rod 313 can better lock onto the interference rope 316 , thereby preventing the interference rope 316 from being separated from one end of the top rod 313 .

[0040] Going further;

[0041] In an optional embodiment, an alarm 317 is fixed to the inner wall of the isolation metal cover 301 .

[0042] In this embodiment: after the fire source is extinguished, smoke will be generated. At this time, the smoke sensor (not shown in the figure) inside the alarm 317 sends a signal to the alarm 317 to control the alarm 317 to start, thereby reminding the staff to handle it, further improving the use effect of the device.

[0043] It should be noted that a smoke sensor is installed inside the alarm 317, which can monitor the smoke inside the isolation metal cover 301 in real time at all times.

[0044] The working principle and use process of the present invention are as follows: when the intelligent photovoltaic protector is in use, the magnetism generated by the strong magnetic sheet 304 adsorbs the isolation metal cover 301 on the surface of the installation guide rail 1 with the cooperation of the strong magnetic sheet 304, thereby completing the installation of the isolation metal cover 301 and then completing the installation of the protector body 2, thereby improving the installation efficiency of the protector body 2. This operation is more practical and convenient. At the same time, the setting of the limiting groove 303 makes the limiting groove 303 stuck on the installation guide rail 1, thereby being able to play an upper and lower limit effect on the isolation metal cover 301 to avoid falling off, thereby further improving the use effect of the device. The metal cover 302 is connected to the isolation metal cover 301 through the strong magnetic strip 1 305 and the strong magnetic strip 2 306. The metal cover 302 is convenient to open and close. A plurality of wires are passed through the wire hole 1 308 and the wire hole 2 309 according to the connection situation and connected to the terminal of the protector body 2. Then the strong magnetic strip 2 306 on the metal cover 302 is adsorbed with the strong magnetic strip 1 305 to seal the isolation metal cover 301. When the heat generated by the poor contact of the terminal wire connector causes combustion and a fire source occurs, in this process, the isolation metal cover 301 and the metal cover 302 are both made of metal, thereby avoiding involving other protector bodies 2, avoiding the spread of the fire source, reducing losses, further improving the use effect of the device, and meeting actual use needs. Heat dissipation holes 307 are provided on both sides of the isolation metal cover 301, which can When the fire source appears at a certain port of the protector body 2, one of the groups of resistance ropes 316 will burn out, and the obstruction of the two groups of top rods 313 will be released. Since the card slots 314 on the top rods 313 can better be stuck on the resistance ropes 316, the resistance ropes 316 will not be separated from one end of the top rods 313. When the obstruction of the two groups of top rods 313 is released, the other group of resistance ropes 316 will find it difficult to support the rebound force of the spring 312 and cannot withstand the thrust of the top rod 313. At this time, the blades 315 on the other two groups of top rods 313 will contact the other group of unbroken resistance ropes 316 to cut the other group of unbroken resistance ropes 316. At this time, the two groups of resistance ropes 316 are In the disconnected state, the spring 312 rebounds and drives the L-shaped metal baffle 310 to move. At the same time, the setting of the telescopic rod 311 can make the L-shaped metal baffle 310 more stable during movement. As the top rod 313 moves, the heat dissipation hole 307 is blocked, so that the isolation metal cover 301, the metal cover plate 302 and the L-shaped metal baffle 310 form a sealed space, thereby reducing air entry and achieving a rapid fire extinguishing effect. When the fire source is extinguished, smoke will be generated. At this time, the smoke sensor inside the alarm 317 (not shown in the figure) sends a signal to the alarm 317 to control the alarm 317 to start, thereby reminding the staff to handle it, further improving the use effect of the device.
