Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of DC power supply technology, and more specifically to a DC power supply that is easy to clean of dust. Background Technology
[0002] A DC power supply system is a device that provides stable and reliable DC power to control, signal, protection, and automatic devices in substations, power plants, communication equipment rooms, and other locations. It plays a vital role in ensuring the normal operation of power systems and other important systems.
[0003] DC power supply panels are typically installed indoors, such as in the control room or communication room of a substation. Even so, dust may still accumulate inside. This dust can enter the DC power supply panel through ventilation openings, cabinet door gaps, etc. When dry air flows inside the DC power supply panel, the dust particles can easily become statically charged when they rub against the surfaces of charging modules, power distribution units, and other equipment. This static electricity can easily damage the battery pack, so it is necessary to clean the dust inside the DC power supply panel regularly.
[0004] However, in practice, it has been noted that the internal space of the DC power supply is relatively small. When cleaning the dust inside, cleaning tools need to be inserted into the DC power supply for cleaning. The small range of movement during cleaning can easily affect the cleaning effect. Incomplete cleaning can also cause dust to accumulate again, resulting in a greater risk of damage to the DC power supply during use. Utility Model Content
[0005] The purpose of this invention is to provide a DC power supply panel that facilitates dust removal. The sliding fit between the dovetail-shaped slide rail and the dovetail-shaped slide groove facilitates the removal of the battery pack. Furthermore, the rotating linkage bracket on the side of the fixed horizontal plate increases the distance between the two fixed horizontal plates, thereby facilitating the cleaning of dust deposited on the battery pack. This addresses the technical problems mentioned in the background section.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A DC power supply panel that is easy to clean dust includes a DC power supply panel frame, an electrical unit installed inside the DC power supply panel frame, a battery pack located below the electrical unit, and the battery pack being fixedly connected to a mounting bracket located inside the DC power supply panel frame.
[0008] The mounting bracket includes fixed horizontal plates arranged in a rectangular array, each of which is equipped with a battery pack. The battery pack has a battery arranged in a rectangular array. The bottom of the fixed horizontal plate is integrally provided with a reinforcing protrusion. The bottom of the fixed horizontal plate is fixedly connected with a dovetail-shaped slide groove arranged in a rectangular array. Each dovetail-shaped slide groove is slidably fitted with a dovetail-shaped slide rail.
[0009] Both sides of the fixed horizontal plate are fixedly connected to a central shaft, and both sides of the fixed horizontal plate are symmetrically provided with limit grooves.
[0010] As a further technical solution of this utility model, both sides of the fixed horizontal plate are movably connected to a rotating connecting rod frame, and the central shaft on the side of the fixed horizontal plate is movably connected to the rotating connecting rod frame.
[0011] As a further technical solution of this utility model, the rotating linkage frame has a central turntable, both ends of which are integrally provided with extension plates, and a rotating plate that intersects with the extension plates is provided on the side of the central turntable away from the fixed horizontal plate.
[0012] As a further technical solution of this utility model, the ends of the central shaft rods respectively penetrate the central shaft positions of the central turntable and the rotating plate, and the end of the extension plate away from the central turntable is fixedly connected to both ends of the rotating plate with T-shaped pin rods.
[0013] As a further technical solution of this utility model, the central turntable is provided with positioning through holes in a ring array, and a locking bolt is threadedly connected to the rotating plate, with the end of the locking bolt penetrating the rotating plate and engaging with the positioning through hole.
[0014] As a further technical solution of this utility model, the end of the T-shaped pin rod passes through the limiting slide groove, and the T-shaped pin rod and the limiting slide groove are in sliding fit.
[0015] As a further technical solution of this utility model, the dovetail slide rail is fixedly connected to the inner side of the DC power supply box frame, and both sides of the DC power supply box frame are fixedly connected to outer side plates, while a heat dissipation top plate is fixedly connected to the top of the outer side plates.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This utility model supports multiple layers of fixed horizontal plates by means of intersecting extension plates and rotating plates. By adjusting the angle between the extension plates and rotating plates, the spacing between the multiple fixed horizontal plates can be adjusted, thereby facilitating the cleaning of dust from the surface of the battery pack mounted on the fixed horizontal plates.
[0018] This utility model allows the mounting bracket and battery pack to be removed from the inside of the DC power supply box frame by sliding cooperation between the dovetail slide rail and the dovetail slide groove. This eliminates the need for workers to insert dust cleaning tools into the inside of the DC power supply box frame, increasing the cleaning space for dust and making it easier to clean the dust deposited on the battery pack.
[0019] This invention uses positioning through holes arranged in a ring on the central turntable and locking bolts on the rotating plate to adjust the angle between the extension plate and the rotating plate, and to fix the relative position between the extension plate and the rotating plate.

[0030] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figure 1-8 This utility model provides a DC power supply screen that is easy to clean dust, including a DC power supply screen frame 1, an electrical unit 3 installed on the inner side of the DC power supply screen frame 1, a battery pack 7 provided below the electrical unit 3, and the battery pack 7 is fixedly connected to the mounting bracket 6 located on the inner side of the DC power supply screen frame 1.
[0032] The mounting bracket 6 includes fixed horizontal plates 61 arranged in a rectangular array. Each fixed horizontal plate 61 is equipped with a battery pack 7, wherein the battery pack 7 has a battery arranged in a rectangular array. The bottom of the fixed horizontal plate 61 is integrally provided with a reinforcing protrusion 64. The bottom of the fixed horizontal plate 61 is fixedly connected with a dovetail-shaped slide groove 10 arranged in a rectangular array. Each dovetail-shaped slide groove 10 is slidably fitted with a dovetail-shaped slide rail 9.
[0033] Both sides of the fixed horizontal plate 61 are fixedly connected to the central shaft rod 63, and both sides of the fixed horizontal plate 61 are symmetrically provided with limit grooves 62.
[0034] In this embodiment, rotating linkages 8 are movably connected to both sides of the fixed horizontal plate 61, and the central shaft 63 on the side of the fixed horizontal plate 61 is movably connected to the rotating linkages 8.
[0035] In this embodiment, the rotating linkage frame 8 has a central turntable 81, with extension plates 83 integrally provided at both ends of the central turntable 81, and a rotating plate 84 intersecting with the extension plate 83 is provided on the side of the central turntable 81 away from the fixed horizontal plate 61.
[0036] Furthermore, the ends of the central shaft 63 pass through the central shaft positions of the central turntable 81 and the rotating plate 84, respectively, and the end of the extension plate 83 away from the central turntable 81 and both ends of the rotating plate 84 are fixedly connected with T-shaped pins 86.
[0037] Furthermore, the central turntable 81 is provided with positioning through holes 82 in a ring array, and the rotating plate 84 is threaded with locking bolts 85, the end of the locking bolts 85 passing through the rotating plate 84 and engaging with the positioning through holes 82.
[0038] Furthermore, the end of the T-shaped pin 86 passes through the limiting groove 62, and the T-shaped pin 86 and the limiting groove 62 are in sliding engagement.
[0039] In this embodiment, the dovetail slide rail 9 is fixedly connected to the inner side of the DC power supply box frame 1, and both sides of the DC power supply box frame 1 are fixedly connected to the outer side plate 2, while the top of the outer side plate 2 is fixedly connected to the heat dissipation top plate 5.
[0040] By adopting the above technical solution, the mounting bracket 6 and battery pack 7 are removed from the DC screen box frame 1 through the sliding fit between the dovetail slide rail 9 and the dovetail slide groove 10. Then, the locking bolt 85 is loosened, and the included angle between the extension plate 83 and the rotating plate 84 is adjusted to increase the spacing between the multiple fixed horizontal plates 61. Then, the locking bolt 85 is tightened until the end of the locking bolt 85 is inserted into the positioning through hole 82 in a suitable position, which facilitates the cleaning of the dust deposited on the battery pack 7.
[0041] In this embodiment, the electrical unit 3 has a charging module, a monitoring module, and a power distribution unit. AC mains power is input to the charging module of the electrical unit 3 in the DC power supply. After the charging module converts the AC power into DC power, it charges the battery on one hand and distributes the DC power to each load through the power distribution unit on the other hand.
[0042] More specifically, when the AC mains power is interrupted, the battery automatically supplies power to the load through the power distribution unit to ensure the normal operation of the load equipment.
[0043] Furthermore, both ends of the DC power supply frame 1 are movably connected to glass doors 4, and each glass door 4 is embedded with a glass observation window, which allows workers to easily view the inside of the DC power supply.
[0044] The working principle of this utility model is as follows: When it is necessary to clean the dust inside the DC screen, pull the mounting bracket 6 forward. The dovetail-shaped slide groove 10 and the dovetail-shaped slide rail 9 at the bottom of the mounting bracket 6 cooperate with each other to remove the mounting bracket 6 from the inside of the DC screen box frame 1. Then loosen the locking bolt 85 and adjust the included angle between the extension plate 83 and the rotating plate 84. Since both ends of the extension plate 83 and the rotating plate 84 are provided with T-shaped pins 86, the sliding cooperation between the T-shaped pins 86 and the limiting slide groove 62 causes multiple fixed horizontal plates 61 arranged in a rectangular array to move upward, increasing the distance between the two fixed horizontal plates 61, which facilitates the cleaning of the dust deposited on the battery pack 7. Then tighten the locking bolt 85 until the end of the locking bolt 85 is inserted into the positioning through hole 82 in a suitable position to prevent the multiple fixed horizontal plates 61 from sliding during dust cleaning.
