[0001] This utility model relates to the field of detection instrument technology, and more specifically, to an intelligent string detector with a dustproof sealing mechanism. Background Technology

[0002] Intelligent string detectors are smart devices installed in photovoltaic power plants to monitor, collect, and transmit electrical parameters and status information at the photovoltaic string level in real time. They are a key component of the digital and intelligent operation and maintenance of photovoltaic power plants. However, after prolonged use, existing intelligent string detectors may experience loosening at structural connections, leading to unstable connections and rendering the tests ineffective. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an intelligent string detector with a dustproof sealing mechanism, which has the advantage that the interface will not fall off.

[0010] As a preferred embodiment of this utility model, there are multiple connection ports, which are equidistantly distributed on the left and right sides of the chassis. There are multiple connection components, each corresponding to one of the multiple connection ports.

[0011] As a preferred embodiment of this utility model, there are multiple locking rods, locking slots, and MC interfaces, and the multiple locking rods are respectively engaged with the multiple locking slots.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model features a groove inside a fixed block, a slider slidably connected inside the groove, a connecting block fixedly installed on the outside of the slider, and a fixed plate fixedly installed at the end of the fixed block away from the chassis.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides an intelligent string detector with a dustproof sealing mechanism, including a chassis 1. A connection port 2 is fixedly installed inside the chassis 1. A slot 5 is opened inside the connection port 2. A locking rod 4 is locked inside the slot 5. A connecting component 3 is fixedly installed on the outside of the locking rod 4. An MC interface 6 is fixedly installed on the outside of the connecting component 3.

[0023] By inserting the external line into the MC interface 6, the connecting component 3 is installed with the connecting port 2 through the snap-fit ​​action of the lever 4 and the slot 5, so that the line is connected in series. At this time, the device can detect the line of each component in real time, which facilitates the normal operation of each component. If a fault occurs, it is convenient for the staff to carry out timely maintenance.

[0024] Among them, a fixing block 7 is fixedly installed on the outside of the chassis 1, a sliding groove 8 is opened inside the fixing block 7, a slider 9 is slidably connected inside the sliding groove 8, a connecting block 10 is fixedly installed on the outside of the inside of the slider 9, a fixing plate 12 is fixedly installed at the end of the fixing block 7 away from the chassis 1, a telescopic rod 13 is fixedly installed inside the fixing plate 12, and a spring 14 is sleeved on the outside of the telescopic rod 13.

[0025] When connecting the circuit, insert the circuit into the limiting rod 11. At this time, the spring 14 will provide elastic force to push the connecting block 10 towards the chassis 1, so that the connecting block 10 moves through the sliding connection between the slider 9 and the slide groove 8. Since the slider 9 and the limiting rod 11 are fixedly connected, the chassis 1 will squeeze the MC interface 6 towards the connection port 2, so that the circuit connection always remains stable and will not loosen.

[0026] Among them, PG-1115 is fixedly installed on the outside of chassis 1. PG-1115 is located at the bottom of connection port 2 and on the right side of chassis 1.

[0027] The main function of PG-1115 is to keep the cable connection sealed, preventing moisture or dust from entering the interior of the chassis 1 and reducing the lifespan of the components.

[0028] The chassis 1 has a fuse bracket 16 and a base plate 19 fixedly installed inside. The fuse bracket 16 has a PCB mounting plate 17 and an electrical mounting rail 18 fixedly installed in front of it. The base plate 19 has a circuit board 20 fixedly installed in front of it.

[0029] The main function of the circuit board 20 is to work with the fuse bracket 16 and the PCB mounting plate 17 to facilitate the normal connection of the internal circuit and ensure the normal use of the detection function.

[0030] Among them, wall-penetrating terminal 1 21 and wall-penetrating terminal 22 are fixedly installed on the outside of the chassis 1, and both wall-penetrating terminal 1 21 and wall-penetrating terminal 22 are located on the left side of the chassis 1.

[0031] Through-wall terminal 1 21 and through-wall terminal 2 22 are available in different models. Their main function is to enable safe and reliable transmission of current or signals from the outside to the inside of the equipment, while ensuring the equipment's airtightness.

[0032] Among them, a fuse-type isolator 23 is fixedly installed in front of the electrical installation rail 18, and the fuse-type isolator 23 has an installation hole 24 inside.

[0033] There are multiple mounting holes 24, which are located inside the chassis 1. Their main function is to allow personnel to clearly see that the circuit has been isolated during equipment maintenance, repair, or debugging, thereby preventing accidental closure and ensuring personal safety. This is its most important safety function.

[0034] There are multiple connection ports 2, which are distributed at equal intervals on the left and right sides of the chassis 1. There are multiple connection components 3, which correspond to multiple connection ports 2 respectively.

[0035] Multiple connecting components 3 drive multiple MC interfaces 6 to connect to the connection port 2 through the snapping action of multiple clamps 4 and multiple slots 5. At the same time, since there are many devices after the photovoltaic panels are laid, they are connected to multiple connection ports 2 through different lines, so that the device can test different components at the same time, improving the testing effect. Also, since the connection points of multiple connection ports 2 are relatively far apart, the lines can be sorted in advance when connecting the lines to prevent them from getting tangled.

[0036] There are multiple locking rods 4, locking slots 5 and MC interfaces 6, with multiple locking rods 4 engaging with multiple locking slots 5 respectively.

[0037] Multiple MC interfaces 6 are driven by multiple levers 4 to engage with multiple slots 5, enabling the internal circuitry of the MC interface 6 to connect with the connection port 2 and quickly connect with the components inside the chassis 1, thus improving the stability of the connection.

[0038] Working principle and usage process of this utility model:

[0039] Firstly, a slot 5 is provided inside the connection port 2, and a lever 4 is engaged inside the slot 5. A connecting component 3 is fixedly installed on the outside of the lever 4, and an MC interface 6 is fixedly installed on the outside of the connecting component 3. By inserting the external line into the MC interface 6, the connecting component 3 is installed in the connection port 2 through the engagement of the lever 4 and the slot 5, so that the line is connected in series. At this time, the device can detect the line of each component in real time, which facilitates the normal operation of each component. If a fault occurs, it is convenient for the staff to carry out timely maintenance.

[0040] Secondly, a sliding groove 8 is provided inside the fixed block 7, and a slider 9 is slidably connected inside the sliding groove 8. A connecting block 10 is fixedly installed inside and outside the slider 9. A fixed plate 12 is fixedly installed at the end of the fixed block 7 away from the chassis 1. A telescopic rod 13 is fixedly installed inside the fixed plate 12, and a spring 14 is sleeved on the outside of the telescopic rod 13. When the circuit is connected, the circuit is inserted into the limiting rod 11. At this time, the spring 14 will provide elastic force to push the connecting block 10 towards the chassis 1, so that the connecting block 10 moves through the sliding connection between the slider 9 and the sliding groove 8. Since the slider 9 and the limiting rod 11 are fixedly connected, the chassis 1 will squeeze the MC interface 6 towards the connection port 2, so that the circuit connection always remains stable and will not loosen.

[0041] Finally, multiple connection ports 2 are fixedly installed on the outside of the chassis 1, and these multiple connection ports 2 are evenly distributed on the left and right sides of the chassis 1. There are also multiple connection components 3, each corresponding to a different connection port 2. The multiple connection components 3 drive multiple MC interfaces 6 to connect with the connection ports 2 through the snapping action of multiple levers 4 and multiple slots 5. At the same time, since there are many devices after the photovoltaic panels are laid, they are connected to multiple connection ports 2 through different lines, so that the device can simultaneously detect different components, improving the detection effect. Also, since the connection points of the multiple connection ports 2 are relatively far apart, the lines can be pre-organized during the connection process to prevent the lines from getting tangled.
