Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic cable temperature monitoring, specifically to a temperature monitoring device for photovoltaic cables. Background Technology
[0002] Photovoltaic cables are an important medium for connecting solar panels and inverters, responsible for transmitting electrical energy to the power grid or energy storage systems. Therefore, they are often used in photovoltaic power station systems. However, during the actual operation of photovoltaic power stations, faults such as loose connections and arcing sometimes occur at cable joints. Therefore, in order to ensure the safety of the overall line, temperature monitoring equipment is installed at the joints. Temperature sensors, along with controllers and wireless communication modules, are used to transmit temperature data to the monitoring terminal, enabling monitoring of the temperature at the joints and ensuring timely response in case of faults.
[0003] However, existing temperature monitoring equipment lacks protection between the cable connectors and the internal components during operation. When the connectors malfunction, high temperatures can be generated, even leading to fires. These high temperatures can damage the internal components of the monitoring equipment, especially since some monitoring devices contain lithium batteries for power supply, which can easily cause more serious accidents. Therefore, this type of temperature monitoring equipment has certain safety hazards in its structural design. Utility Model Content
[0004] Based on the above description, this utility model provides a temperature monitoring device for photovoltaic cables to solve the problem that existing photovoltaic cable temperature monitoring devices do not provide sufficient protection for their internal components.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a temperature monitoring device for photovoltaic cables, including a device body and a temperature sensor, wherein the temperature sensor is installed on the inner wall of the device body;
[0006] The inner cavity of the main body of the equipment is equipped with a protective component, which includes a protective plate, a limiting groove and a support plate. The protective plate is fixedly installed in the inner cavity of the main body of the equipment and is designed as a rectangle. The limiting groove is opened on the side wall of the protective plate. The support plate is fixedly installed on the inner wall of the protective plate. A protective part is installed on one side of the protective plate.
[0007] A cover plate is movably connected to one side of the main body of the equipment via a hinge. An installation groove is provided on the side wall of the main body of the equipment. A cable is installed inside the installation groove, and the connector of the cable is located in the inner cavity of the protective plate.
[0008] Furthermore, there are two limiting grooves, which are symmetrically distributed on the side wall of the protective plate, and the two ends of the cable pass through the limiting grooves on both sides respectively.
[0009] Based on the above technical solution, the present invention can be further improved as follows.
[0010] Furthermore, a detection hole is provided on one side of the protective plate, and the detection end of the temperature sensor passes through the detection hole and enters the inner cavity of the protective plate.
[0011] Furthermore, a sealing block is fixedly installed on one side of the cover plate. There are four sealing blocks, and the four sealing blocks enter the interior of the mounting groove and the limiting groove as the cover plate is flipped.
[0012] Furthermore, the protective part includes a vertical plate, a slot, a first connecting plate, a second connecting plate, and a baffle. The slot is formed at the top of the vertical plate, the bottom of the vertical plate is fixedly connected to the top of the first connecting plate, and the end of the first connecting plate away from the vertical plate is fixedly connected to the side wall of the support plate.
[0013] Furthermore, one end of the second connecting plate is fixedly connected to one side of the vertical plate, and the end of the second connecting plate away from the vertical plate is fixedly connected to one end of the baffle.
[0014] Furthermore, the baffle is designed in a U-shape, and the temperature sensor passes through one end of the detection hole and then enters the inner cavity of the slot, with the inner wall of the slot fitting against the side wall of the temperature sensor.
[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0016] 1. This utility model sets up a protective component inside the main body of the equipment, and with the cable passing through the limiting groove, the cable is placed in the inner cavity of the protective plate. This can use the protective plate to isolate the cable from other components inside the main body of the equipment, and prevent damage to the internal components of the main body of the equipment in the event of high temperature or fire.
[0017] 2. By opening a detection hole in the protective plate and having the detection end of the temperature sensor pass through the detection hole, the distance between the detection end of the temperature sensor and the cable can be brought closer, resulting in more accurate temperature detection. At the same time, for the safety of the temperature sensor, a protective part is added to the support plate. The U-shaped baffle in the protective part provides protection for the detection end of the temperature sensor, preventing the fire from directly contacting the detection end of the temperature sensor in the event of a fire.

[0032] Please see Figure 1 and Figure 2 A temperature monitoring device for photovoltaic cables includes a device body 1 and a temperature sensor 9. The temperature sensor 9 is installed on the inner wall of the device body 1 and is used to detect the temperature inside the device body 1. When the temperature is detected to be too high, it will transmit a signal to the controller inside the device body 1 to activate the alarm light.
[0033] The inner cavity of the main body 1 is equipped with a protective component 5. The protective component 5 includes a protective plate 501, a limiting groove 502 and a support plate 503. The protective plate 501 is fixedly installed in the inner cavity of the main body 1 and the protective plate 501 is designed as a rectangle. The limiting groove 502 is opened on the side wall of the protective plate 501. The support plate 503 is fixedly installed on the inner wall of the protective plate 501. A protective part 7 is installed on one side of the protective plate 501. The protective plate 501 is a fireproof plate.

An installation groove 3 is provided on the side wall of the main body 1. A cable 4 is installed inside the installation groove 3. The connector of the cable 4 is located in the inner cavity of the protective plate 501. By placing the connector of the cable 4 in the inner cavity of the protective plate 501, the protective plate 501, together with the cover plate 2, can achieve temperature isolation. At the same time, in the event of a fire, it can also protect other components inside the main body 1, preventing damage to other components caused by the fire.
[0035] Please see Figure 2 and Figure 4 In this embodiment, there are two limiting grooves 502. The two limiting grooves 502 are symmetrically distributed on the side wall of the protective plate 501, and the two ends of the cable 4 pass through the limiting grooves 502 on both sides respectively.
[0036] Please see Figure 2 and Figure 4 In this embodiment, a detection hole 6 is provided on one side of the protective plate 501. The detection end of the temperature sensor 9 passes through the detection hole 6 and enters the inner cavity of the protective plate 501. The detection hole 6 on the protective plate 501 makes it easier for the temperature sensor 9 to be close to the cable 4, so as to avoid the temperature detection being inaccurate due to the isolation of the protective plate 501.
[0037] Please see Figure 2 and Figure 4 In this embodiment, a sealing block 8 is fixedly installed on one side of the cover plate 2. There are four sealing blocks 8. As the cover plate 2 is flipped, the four sealing blocks 8 enter the interior of the mounting groove 3 and the limiting groove 502.
[0038] After flipping the cover plate 2, the sealing block 8 on the cover plate 2 enters the interior of the mounting groove 3 and the limiting groove 502 to limit and fix the cable 4.
[0039] Please see Figure 2 and Figure 3 The protective part 7 in this embodiment includes a vertical plate 701, a slot 702, a first connecting plate 703, a second connecting plate 704, and a baffle 705. The slot 702 is formed on the top of the vertical plate 701. The bottom of the vertical plate 701 is fixedly connected to the top of the first connecting plate 703. The end of the first connecting plate 703 away from the vertical plate 701 is fixedly connected to the side wall of the support plate 503.
[0040] The first connecting plate 703 and the vertical plate 701 will contact the detection end of the temperature sensor 9 to provide support for the detection end of the temperature sensor 9.
[0041] Please see Figure 2 and Figure 3 In this embodiment, one end of the second connecting plate 704 is fixedly connected to one side of the vertical plate 701, and the end of the second connecting plate 704 away from the vertical plate 701 is fixedly connected to one end of the baffle 705.
[0042] The second connecting plate 704 is used to connect the first connecting plate 701 and the baffle 705, providing support for the baffle 705, while the baffle 705 is used to provide barrier protection for the detection end of the temperature sensor.
[0043] Please see Figure 2 and Figure 3 In this embodiment, the baffle 705 is designed in the shape of a U-shape, and the temperature sensor 9 passes through one end of the detection hole 6 and then enters the inner cavity of the slot 702. The inner wall of the slot 702 is in contact with the side wall of the temperature sensor 9.
[0044] After passing through the slot 702, the temperature sensor 9 is protected by the baffle 705. In the event of a fire, the U-shaped baffle 705 can block the fire and prevent the fire from directly contacting the detection end of the temperature sensor 9.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
