Abstract
Description
Technical Field
[0001] This utility model relates to the field of microgrid terminal box technology, and in particular to a microgrid terminal box that is easy to install. Background Technology
[0002] A microgrid is a small-scale power generation and distribution system comprised of distributed power sources, energy storage devices, energy conversion devices, related loads, and monitoring and protection devices. The power sources in a microgrid are mostly small-capacity distributed power sources, i.e., small units with power electronic interfaces, including micro gas turbines, fuel cells, photovoltaic cells, small wind turbines, and energy storage devices such as supercapacitors, flywheels, and batteries. A smart microgrid is a small-scale, decentralized, independent system capable of self-control, protection, and management. It can operate with the external power grid or in isolation. It integrates distributed power sources, energy storage devices, energy conversion devices, related loads, and monitoring and protection devices into a single enclosure. By distributing central processing unit modules, digital input modules, digital output modules, power acquisition modules, bus expansion terminal modules, and power supply modules within the enclosure, it automatically coordinates and centrally controls the system based on the collected data.
[0003] In the existing technology, sometimes it is necessary to fix the terminal box to a pole (such as a utility pole). The most common connecting part is the clamp. Different sizes of utility poles require different models of clamps. However, the terminal box is generally not equipped with clamps when it leaves the factory, and some poles are not standard parts. This makes it necessary for assembly workers to modify the clamps themselves, which brings inconvenience to the installation. Utility Model Content
[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a microgrid terminal box that is easy to install.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A microgrid terminal box that is easy to install includes a terminal box body. The front of the terminal box body is provided with a door. The interior of the terminal box body is provided with a vertically mounted mounting plate. The back of the terminal box body is provided with multiple pairs of C-shaped guide rails spaced apart along the height direction of the terminal box body. Each pair of C-shaped guide rails is arranged in a "V" shape. Bolts are slidably connected inside the C-shaped guide rails. A clamping plate is sleeved on two bolts located in the same pair of C-shaped guide rails. The clamping plate has a strip-shaped hole for the bolts to pass through. A nut is threaded onto the bolt. The clamping plate is located between the nut and the C-shaped guide rail.
[0007] Furthermore, the strip hole is in the shape of an inverted "V".
[0008] Furthermore, side heat dissipation holes are provided on both the left and right side panels of the terminal box, and water baffles are connected to the inner walls of the left and right side panels of the terminal box corresponding to the side heat dissipation holes. Ventilation holes are provided on the water baffles, and the ventilation holes are staggered with the side heat dissipation holes.
[0009] Furthermore, the bottom side panel of the terminal housing is provided with bottom heat dissipation holes and wiring holes.
[0010] Furthermore, a wiring board is connected to the inner wall of the right side panel of the terminal housing.
[0011] The beneficial effects of this utility model are as follows: When installing the terminal box onto the upright, first, the C-shaped guide rail abuts against the side of the upright, then the bolts are inserted into the C-shaped guide rail. Under the action of gravity, the two bolts in the same pair of C-shaped guide rails will automatically abut against the surface of the upright. Then, the clamping plate is fitted onto the bolts, and finally the nut is tightened. The C-shaped guide rail, the two bolts, and the clamping plate clamp the upright from the front, left, right, and rear sides, respectively, providing excellent stability. Furthermore, the distance between the clamping plate and the C-shaped guide rail, as well as the two oppositely arranged bolts, can be adjusted to accommodate uprights of various sizes, providing excellent adaptability and facilitating the installation of the terminal box.

[0017] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0018] like Figures 1-4 As shown, a microgrid terminal box that is easy to install includes a terminal box body 1, which is rectangular in shape. The front end of the terminal box body 1 is open. A door 2 is hinged to the right side of the open end of the terminal box body 1. A door lock 21 is provided on the left side of the door 2. When the door 2 is closed, the door lock 21 can fix the door 2 and the terminal box body 1 together. A mounting plate 3 is fixed to the inner wall of the rear side panel of the terminal box body 1. The mounting plate 3 has mounting holes 31 for mounting electronic components. Two mounting holes are spaced apart along the height direction of the terminal box body 1 on the back side. For the C-shaped guide rail 4, each pair of C-shaped guide rails 4 is arranged in a "V" shape. Bolts 5 are slidably connected inside the C-shaped guide rail 4. Specifically, the bolts 5 are set perpendicular to the C-shaped guide rail 4, and the head of the bolt 5 is slidably connected inside the C-shaped guide rail 4. The shank of the bolt 5 extends out from the opening side of the C-shaped guide rail 4. A clamping plate 6 is sleeved on the two bolts 5 located in the same pair of C-shaped guide rails 4. The clamping plate 6 has a strip hole 61 for the bolt 5 to pass through. The strip hole 61 is in the shape of an inverted "V". A nut 7 is threaded onto the bolt 5. The clamping plate 6 is located between the nut 7 and the C-shaped guide rail 4.
[0019] In actual installation, first, the C-shaped guide rail 4 is placed against the side of the upright. Then, the head of the bolt 5 is inserted into the C-shaped guide rail 4. Under the action of gravity, the two bolts 5 in the same pair of C-shaped guide rails 4 will automatically abut against the surface of the upright. Then, the clamping plate 6 is fitted onto the bolt 5. Since the strip hole 61 on the clamping plate 6 can effectively limit the bolt 5, it prevents the distance between the two bolts 5 from increasing. Finally, tighten the nut 7. The C-shaped guide rail 4, the two bolts 5, and the clamping plate 6 clamp the upright from the front, left, right, and rear sides, respectively, which has excellent stability. Moreover, the distance between the clamping plate 6 and the C-shaped guide rail 4, as well as the two bolts 5, can be adjusted to adapt to uprights of various sizes, which has good adaptability and facilitates the installation of the terminal box 1.
[0020] In this embodiment, side heat dissipation holes 11 are provided on both the left and right side panels of the terminal housing 1. Water baffles 8 are connected to the inner walls of the left and right side panels of the terminal housing 1 corresponding to the side heat dissipation holes 11. Ventilation holes 81 are provided on the water baffles 8. The ventilation holes 81 are staggered with the side heat dissipation holes 11. The water baffles 8 can not only effectively prevent external rainwater from entering the interior of the terminal housing 1, but the ventilation holes 81 staggered with the side heat dissipation holes 11 can also enhance the breathability.
[0021] In this embodiment, the bottom side panel of the terminal housing 1 is provided with bottom heat dissipation holes 12 and wiring holes 13 to facilitate bottom heat dissipation and wiring.
[0022] In this embodiment, a wiring board 9 is connected to the inner wall of the right side panel of the terminal housing 1 to facilitate wiring inside the terminal housing 1.
[0023] 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., within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
