Technical Field
[0001] The utility model relates to the technical field of bus ducts, in particular to a bus duct with adjustable length for a photovoltaic energy storage system. Background Art
[0002] Bus duct is a closed metal device composed of copper and aluminum busbars. It is used to distribute high power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.
[0003] Traditional bus ducts have poor heat dissipation capabilities. When high-power electrical appliances are used, the conductors easily heat up, posing a safety hazard and making installation and construction inconvenient.
[0004] For example, a heat dissipation bus duct disclosed in Chinese patent CN214707042U can start the motor to drive the second chain and the third chain to rotate, so that the electric fan on the side of the chain can follow the trajectory of the chain to better accelerate the air flow inside the bus duct and achieve the heat dissipation effect. The rotation of the fifth gear and the sixth gear can drive the fourth rotating shaft, the roller and the fourth gear to rotate, thereby driving the first chain, the third rotating shaft and the second baffle to rotate, which can effectively enhance the air flow near the second baffle and ventilate with the outside air, thereby improving the heat dissipation capacity of the bus duct and solving the problem of poor heat dissipation capacity of most bus ducts.
[0005] However, the bus duct does not have a length adjustment function. During the installation process, it is often necessary to fine-tune the length of the bus duct, which requires customization of the length specifications of the bus duct, increases costs, and is not convenient to use.
[0006] For this reason, we urgently need to provide a bus duct with adjustable length for a photovoltaic energy storage system. Utility Model Content
[0007] The purpose of the utility model is to provide a bus duct with adjustable length for a photovoltaic energy storage system, so as to solve the problem that the bus duct proposed in the above background technology does not have a length adjustment function. During the installation process, it is often necessary to fine-tune the length of the bus duct, which requires customization of the length specifications of the bus duct, increases costs, and is not convenient to use.
[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bus duct with adjustable length for a photovoltaic energy storage system, comprising a first bus duct body and a second bus duct body, wherein the second bus duct body is slidably connected to the outer sides of the left and right ends of the first bus duct body, and an adjustment mechanism is connected to the inner and outer ends of the first bus duct body and the second bus duct body, wherein the adjustment mechanism comprises a heat dissipation unit and an adjustment unit, wherein the heat dissipation unit is arranged at the front and rear ends of the first bus duct body, and the adjustment unit is arranged at the left and right ends of the first bus duct body.
[0009] The adjustment unit includes a slider, a second threaded rod and a rotating handle. The slider is fixedly connected to the front and rear of the left and right ends of the first bus duct body, the second threaded rod is connected to the inside of the slider, and the rotating handle is fixedly connected to one end of the second threaded rod located in the first bus duct body.
[0010] A further improvement is that a first threaded hole is provided in the middle of the slider, and the outer side of the second threaded rod is threadedly connected to the inner side of the first threaded hole, so that when the rotating handle is turned to drive the second threaded rod in the first threaded hole to rotate, the second threaded rod can move relative to the slider.
[0011] A further improvement is that a slide groove is provided at the middle position of the front and rear ends of the inner side of the second bus duct body, close to one end of the first bus duct body, and the outer side of the end of the slider away from the first bus duct body is slidably connected to the inner side of the slide groove. Thus, the second bus duct body slides along the outer side of the first bus duct body, so that the overall length of the first bus duct body and the second bus duct body is adjusted to the required length, and then the rotating handle is turned to drive the second threaded rod to rotate and move to the inner side of the contact slide groove, so that the second bus duct body can be fixed to the outer side of the first bus duct body, so that the overall length of the bus duct can be adjusted through the adjustment unit.
[0012] A further improvement is that the heat dissipation unit includes a fan, a first threaded rod, a ring, a fixed frame and a filter, the fan is fixedly connected to the middle position of the inner front end of the first bus duct body, the first threaded rod is fixedly connected to the rear side of the first bus duct body, the ring is connected to the outer side of the first threaded rod, the fixed frame is connected to the rear side of the first bus duct body, and the filter is fixedly connected to the inner side of the fixed frame.
[0013] A further improvement is that a through slot is provided at the middle position of the rear end of the first bus duct body, the first threaded rod is fixed to the rear side of the first bus duct body at the four corners of the through slot, the four corners of the interior of the fixing frame are provided with round holes, and the outer side of the first threaded rod is slidably connected to the inner side of the round hole. Therefore, when the fixing frame and the filter are placed on the rear side of the first bus duct body, the round holes at the four corners of the fixing frame will pass through the outer side of the first threaded rod, thereby limiting the movement of the fixing frame during assembly and disassembly.
[0014] A further improvement is that the inner side of the collar is provided with an internal thread, the outer side of the first threaded rod is threadedly connected to the inner side of the collar, and the front side of the collar abuts against the four corners of the rear side of the fixing frame. Thus, after the fixing frame is placed on the rear side of the first bus duct body and the round hole passes through the first threaded rod, the collar is threadedly connected to the outer side of the first threaded rod until the front side of the collar contacts the four corners of the rear side of the fixing frame, so that the fixing frame can be fixed to the middle position of the rear side of the first bus duct body, completing the installation of the filter.
[0015] A further improvement is that a rubber pad is fixedly connected to the front side of the fixing frame. Therefore, after the fixing frame is fixed to the rear side of the first bus duct body, the rubber pad on the front side of the fixing frame contacts the rear side of the first bus duct body, so that the contact between the rear side of the first bus duct body and the front side of the fixing frame can be kept sealed, and the air entering the first bus duct body can be completely filtered through the filter screen, preventing dust from entering the first bus duct body.
[0016] In summary, the present application discloses a bus duct with adjustable length for a photovoltaic energy storage system.
[0017] According to the technical solution, after the second bus duct body slides along the outer side of the first bus duct body, so that the overall length of the first bus duct body and the second bus duct body is adjusted to the required length, the rotating handle is turned to drive the second threaded rod to rotate while moving to the inner side of the contact slide groove, so that the second bus duct body can be fixed to the outer side of the first bus duct body, so that the overall length of the bus duct can be adjusted through the adjustment unit.
[0018] Furthermore, by starting the fan, external air can enter the first bus duct body from the filter through the through slot, so as to dissipate heat inside the first bus duct body. BRIEF DESCRIPTION OF THE DRAWINGS
