Description

Technical Field

[0001] This utility model belongs to the field of cable trough technology, specifically relating to a cable trough for photovoltaic power generation. Background Technology

[0002] Cable trays are channel devices used to organize and fix wires and cables. They are mainly divided into two categories according to their materials: plastic cable trays (such as PVC and PPO) and metal cable trays (such as aluminum alloy and stainless steel). Common types include: insulated cable trays: suitable for low-voltage power distribution scenarios, with flame-retardant properties; partitioned cable trays: use partitions to separate strong and weak currents to prevent signal interference; and floor-protected cable trays: made of thickened rubber or PVC material, suitable for temporary wiring scenarios.

[0003] Currently, when cables are in operation, due to the current flowing inside and the cable's inherent resistance, the cable itself generates heat. Prolonged exposure to this high-temperature environment can cause the insulation layer to become brittle, crack, or break, leading to spontaneous combustion. Since current cable troughs generally lack flame-retardant structures, when a cable catches fire, the fire can spread, and the resulting smoke can corrode unburned cables, causing significant losses. Therefore, this paper proposes a cable trough for photovoltaic power generation. Utility Model Content

[0004] The purpose of this invention is to provide a simple and reasonably designed cable trough for photovoltaic power generation in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A cable trough for photovoltaic power generation includes a trough body and a plug-in socket fixedly connected to one end of the trough body. Multiple sets of limiting rods are fixedly connected inside the trough body. Fireproof components are attached to the inner side of adjacent sides of each set of limiting rods. A trough cover is connected to the top of the trough body through a plug-in assembly. A heat dissipation hole is opened on one side of the trough body. A baffle is fixedly connected to one side of the trough body. The baffle is located at one end of the heat dissipation hole.

[0007] As a further optimization of this utility model, the fireproof component includes two fireproof partitions that are attached to the adjacent sides of each set of limiting rods, and fireproof bags are attached to the adjacent sides of the two fireproof partitions. Organic sealing material is fixedly connected to the inner surface of the fireproof bags.

[0008] As a further optimization of this utility model, the fireproof partition is provided with a through hole for the cable to pass through, the organic sealant is tightly wrapped around the outer surface of the cable, and the outer surface of the fireproof partition and the fireproof bag is in contact with the inner surface of the trough.

[0009] As a further optimization of this utility model, the plug-in assembly includes a plug-in groove formed on the top of the groove body, and a plug-in rod is fixedly connected to the bottom of the groove cover. The plug-in rod is plugged into the plug-in groove, and the plug-in rod is set to a "convex" shape, while the plug-in groove is set to a "concave" shape.

[0010] As a further optimization of this utility model, a drainage groove is provided at the bottom of the tank, and one side of the drainage groove is inclined.

[0011] As a further optimization of this utility model, the bottom of the groove is inclined, and the plug-in seat is adapted to the other end of the groove.

[0012] The beneficial effects of this utility model are as follows: By using fireproof partitions, fireproof bags, and organic sealant in combination, the organic sealant tightly wrapped around the outer surface of the cable can form a physical barrier to prevent moisture, dust, corrosive gases, etc. from penetrating the cable surface, avoiding moisture aging of the insulation layer or oxidation and corrosion of the metal conductor, thus extending the service life of the cable. The fireproof partitions and fireproof bags can prevent the spread of fire and the corrosion of other parts of the cable by the smoke generated by the fire when the cable catches fire, thus providing good protection for the cable.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a cable trough for photovoltaic power generation includes a trough body 1 and a plug-in socket 2 fixedly connected to one end of the trough body 1. The bottom of the trough body 1 is inclined. The plug-in socket 2 is adapted to the other end of the trough body 1. The top of the trough body 1 is connected to a trough cover 3 via a plug-in assembly. The plug-in assembly includes a plug-in groove 5 opened on the top of the trough body 1. A plug-in rod 4 is fixedly connected to the bottom of the trough cover 3. The plug-in rod 4 is plugged into the plug-in groove 5, and the plug-in rod 4 is convex, while the plug-in groove 5 is concave. A heat dissipation hole 6 is opened on one side of the trough body 1. The heat dissipation hole 6 is inclined, with the end inside the trough body 1 being the high end and the end outside the trough body 1 being the low end. To prevent water from entering the tank 1 from the external environment, the ventilation holes 6 allow for air exchange in the tank 1, preventing heat buildup inside. A baffle 7 is fixedly connected to one side of the tank 1. The baffle 7 is arc-shaped to prevent water from the environment in which the cable trough is located from entering the cable trough. The baffle 7 is located at one end of the ventilation holes 6. A drainage trough 12 is provided at the bottom of the tank 1. One side of the drainage trough 12 is inclined and higher. The inclined bottom of the tank 1 facilitates the drainage of water inside the tank 1 through the drainage trough 12. Multiple sets of limiting rods 8 are fixedly connected inside the tank 1. Fireproof components are attached to the inner sides of the adjacent sides of each set of limiting rods 8.

[0023] In use, first connect multiple slots 1 through plug-in sockets 2, then fix the multiple slots 1 together with bolts. At this time, install the fireproof component on the cable 13, and then insert the fireproof component into multiple sets of limit rods 8. Then the slot cover 3 can be connected to the slot 1 through plug-in rods 4 and plug-in slots 5.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the fireproof component includes two fireproof partitions 9 that are attached to the adjacent sides of each set of limiting rods 8. Fireproof bags 10 are attached to the adjacent sides of the two fireproof partitions 9. Organic sealant 11 is fixedly connected to the inner surface of the fireproof bag 10. The fireproof partitions 9 have through holes for the cable 13 to pass through. The organic sealant 11 is tightly wrapped around the outer surface of the cable 13. The outer surfaces of the fireproof partitions 9 and the fireproof bags 10 are attached to the inner surface of the tank 1.

[0025] During use, the organic sealant 11 tightly wrapped around the outer surface of the cable 13 forms a physical barrier to prevent moisture, dust, corrosive gases, etc. from penetrating the surface of the cable 13, avoiding moisture aging of the insulation layer or oxidation and corrosion of the metal conductor, and extending the service life of the cable 13. The fireproof partition 9 and fireproof bag 10 can prevent the spread of fire and the corrosion of other parts of the cable 13 by the smoke generated by the fire when the cable 13 catches fire, thus providing good protection for the cable 13. In addition, since the organic sealant 11 is located inside the fireproof partition 9 and the position of the fireproof partition 9 is limited by the limiting rod 8, it can reduce the displacement friction of the cable 13 during vibration or thermal expansion and contraction, and prevent the insulation layer from wearing and cracking. At the same time, the flexible wrapping can absorb some of the external impact force and reduce the probability of mechanical damage.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
