Description

Technical Field

[0001] This utility model relates to the field of power supply harness technology for grain warehouses, specifically a low-voltage DC power supply harness for grain warehouses. Background Technology

[0002] The dedicated low-voltage DC power supply harness for grain silos is a power supply system component specially designed for the grain silo environment. It uses low-voltage DC power transmission to ensure electrical safety under complex grain silo conditions such as humidity and dust. This harness possesses excellent corrosion and abrasion resistance, adapting to the chemical substances and physical wear that may be present inside the grain silo, extending its service life. Its insulation materials meet high safety standards, effectively preventing electrical accidents such as leakage and short circuits, ensuring the safety of grain silo personnel and equipment. Furthermore, the harness has a rational design and clear layout, facilitating installation and maintenance, and can stably support the normal operation of various low-voltage DC equipment within the grain silo, such as lighting and monitoring systems, helping to achieve efficient, safe, and intelligent management of the grain silo.

[0003] Currently, low-voltage DC power supply harnesses used in environments such as grain silos typically employ a single connector for their main line. However, this design often necessitates the use of multiple connectors during main line installation to accommodate varying lengths and layouts.

[0004] However, since these main line connectors are generally placed inside the toolbox, workers need to find the appropriate connector one by one during the installation process. This is not only time-consuming and labor-intensive, but also makes the installation of the wire harness inefficient and affects the overall installation efficiency. Therefore, a special low-voltage DC power supply wire harness for grain warehouses is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a low-voltage DC power supply harness specifically for grain warehouses. It has advantages such as improved ease of installation of main line connectors and solves the problem that existing main line connectors are placed individually inside a toolbox, requiring workers to search for suitable connectors one by one during installation, which is not only time-consuming and labor-intensive but also results in low installation efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A low-voltage DC power supply harness for grain storage includes a female connector, three main line bodies, and nine branch line bodies. The left side of the female connector is provided with an installation structure for connecting and installing the main line bodies.

[0008] The mounting structure includes a main line connector plugged into the right side of the main line body, a branch line connector plugged into the top of the branch line body, a power connection wire plugged into the left side of the branch line connector, a mounting base fixedly connected to the top of the main line connector, a mounting tube fixedly connected to the right side of the mounting base, an adjusting rod slidably connected inside the mounting tube, a first threaded rod fixedly connected to the top of the mounting tube, a threaded cap threadedly connected to the outer peripheral wall of the first threaded rod, a second threaded rod fixedly installed on the outer peripheral wall of the adjusting rod, a support ring fixedly connected to the outer peripheral wall of the second threaded rod, a limit plate slidably connected to the outer peripheral wall of the second threaded rod, and a nut threadedly connected to the outer peripheral wall of the limit plate.

[0009] Furthermore, a limiting ring is fixedly connected to the outer peripheral wall of the adjusting rod, and the limiting ring is slidably connected to the inner peripheral wall of the mounting tube.

[0010] Furthermore, the right ends of the two adjusting rods are respectively fixedly connected to the left side of the two mounting seats on the right side.

[0011] Furthermore, there are three main line connectors, and the three main line bodies are respectively plugged into the left side of the three main line connectors. The first power connector is fixedly connected inside the left main line body, and the second power connector is fixedly connected inside the left main line body.

[0012] Furthermore, the top three branch line bodies are fixedly connected to the bottom of the three main line connectors. There are nine branch line connectors in total. The top of each branch line body is inserted into the bottom of the branch line connector, and the female connector is inserted into the right side of the main line connector.

[0013] Furthermore, the limiting plate is movably connected to the top of the support ring, and the nut is movably connected to the top of the limiting plate.

[0014] Furthermore, the limiting plate has a through hole inside, and the second threaded rod is slidably connected inside the through hole, with the size of the second threaded rod matching that of the through hole.

[0015] Furthermore, the limiting plate has a sliding groove inside, the first threaded rod is slidably connected inside the sliding groove, the size of the first threaded rod is adapted to the sliding groove, the threaded cap is movably connected to the top of the limiting plate, and the limiting plate is slidably connected to the top of the mounting tube.

[0016] Compared with the prior art, this utility model provides a low-voltage DC power supply harness specifically for grain silos, which has the following beneficial effects:

[0017] 1. This special low-voltage DC power supply harness for grain silos connects and installs three main line connectors through two power connection lines, two mounting tubes, and an adjusting rod. The adjusting rod can be adjusted and slid inside the mounting tube to adjust the distance between the three main line connectors to accommodate main line bodies of different lengths. The adjusting rod is limited by the action of a limiting plate, a first threaded rod, and a threaded cap, thereby fixing the three main line connectors after adjustment.

[0018] 2. This grain silo-specific low-voltage DC power supply harness requires only one power source per harness. It features low power consumption, a small number of harnesses, and low line loss. Moreover, one harness can simultaneously meet the different voltage requirements of multiple sets of equipment without affecting the overall output, resulting in significant energy savings. The harness adopts a modular design, consisting of four parts: main line, branch line, terminal, and voltage regulator. In case of a fault, it can be tested in sections without the need for complete replacement, simplifying maintenance and reducing costs. Attached Figure Description

The top of the branch line body 3 is plugged into the bottom of the branch line connector 5 in this embodiment, and the female connector 1 is plugged into the right side of the main line connector 4.

[0026] It should be noted that the main line connector 4 and the branch line connector 5 are used to connect and fix the main line body 2 and the branch line body 3.

[0027] In this embodiment, a branch connector 5 is inserted into the top of the branch body 3, a power connection wire 8 is inserted into the left side of the branch connector 5, a mounting base 9 is fixedly connected to the top of the main connector 4, a mounting tube 10 is fixedly connected to the right side of the mounting base 9, an adjusting rod 11 is slidably connected inside the mounting tube 10, and the right ends of the two adjusting rods 11 are respectively fixedly connected to the left side of the two mounting bases 9 on the right side.

[0028] It should be noted that the distance between two adjacent main line connectors 4 is adjusted by adjusting rod 11.

[0029] In this embodiment, a first threaded rod 12 is fixedly connected to the top of the mounting tube 10, and a threaded cap 13 is threadedly connected to the outer peripheral wall of the first threaded rod 12.

Then push the three main line connectors 4 to the right and insert them into the main line body 2. After the main line connectors 4 are inserted and fixed with the main line body 2, thread the threaded cap 13 to the outer peripheral wall of the first threaded rod 12 and fix the limiting plate 16 by friction. Then insert the branch line body 3 into the bottom of the main line connector 4. Finally, insert the branch line connector 5 into the bottom of the branch line body 3. Then insert the branch line connector 5 and the branch line body 3 one by one.
