Abstract
Description
Technical Field
[0001] This utility model relates to the field of substation technology, and in particular to a ventilated and stable box-type substation. Background Technology
[0002] Prefabricated substations have replaced traditional civil engineering power distribution rooms and substations, becoming a new type of complete power distribution device. They are suitable for residential communities, urban public utilities, bustling city centers, construction power supplies, mines, factories, oil and gas fields, and wind power stations. Users can choose prefabricated substations according to different usage conditions and load levels.
[0003] The exterior of the prefabricated substation is equipped with ventilation windows, and the ventilation windows are equipped with blade structures. The blade structures can play a role in dust and water protection. However, when the equipment has been running for a long time, dust is easy to accumulate on the blades. Dust accumulation will seriously affect the ventilation effect, reduce heat dissipation efficiency, and threaten the stable operation of internal electrical equipment. Since the blade structure is mostly an integrated design and cannot be disassembled separately, it is extremely inconvenient to clean and replace the blades. Summary of the Invention
[0004] To address the aforementioned problems, this utility model proposes a ventilated and stable box-type substation to overcome the shortcomings of existing systems.
[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a ventilated and stable box-type substation, including a box body, an eave at the top of the box body, and multiple ventilation windows on the outside of the box body;
[0006] The ventilation window is equipped with multiple tilted blades. One end of each blade is equipped with a first pivot, which is rotatably connected to the ventilation window. The other end of each blade is equipped with a second pivot, which is rotatably connected to the ventilation window. The blades are detachably connected to the first and second pivots via a snap-fit structure.
[0007] A first frame is provided on one side of the ventilation window, and a second frame is provided on the other side of the ventilation window. Both the first and second frames are fixedly connected to the ventilation window. The first frame is provided with a damping structure to increase the rotational resistance of the first rotating shaft, and the second frame is provided with a connecting rod structure to enable each second rotating shaft to rotate in coordination.
[0008] The further improvement lies in the fact that the tilt angle of each blade is the same.
[0009] A further improvement is that the damping structure includes a rubber ring and a second spring disposed within the first frame. The rubber ring is sleeved on the outside of the first rotating shaft and is slidably connected to the first rotating shaft. One side of the rubber ring contacts the outer wall of the vent window, and the other side of the rubber ring is fixedly connected to the second spring. The end of the second spring away from the rubber ring is fixedly connected to the first rotating shaft.
[0010] A further improvement is that the connecting rod structure includes a connecting plate and a tie rod disposed within the second frame. One end of the connecting plate is fixedly connected to the end of the second rotating shaft away from the blade plate, and the other end of each connecting plate is hinged to the tie rod via a cylindrical pin.
[0011] A further improvement is that the buckle structure includes a mounting block, which is fixedly connected to the opposite sides of the first and second rotating shafts. A slot is provided at one end of the mounting block near the blade, and the left and right ends of the blade are inserted into the slot. The blade is slidably connected to the slot, and an elastic locking pin is provided inside the slot for fixing the blade.
[0012] A further improvement is that the elastic locking pin includes a pin groove formed inside the slot, a pin body is provided in the pin groove, the pin body is slidably connected to the pin groove, the pin body is movably engaged with a pin hole formed on the outside of the blade plate, a first spring is provided in the pin groove to support the pin body, the first spring is fixedly connected to the pin body, and an adjustment device is provided on the outside of the mounting block to adjust the support force of the first spring.
[0013] A further improvement is that the adjusting device includes an adjusting bolt, which is assembled on the outside of the mounting block. The adjusting bolt is screwed into the pin groove and threadedly connected to the pin groove. A rotating ring is provided at the end of the first spring away from the pin body. The rotating ring is fixedly connected to the first spring and rotatably connected to the adjusting bolt.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] When the blade is moved, the linkage structure will drive other blades to open and close synchronously to adjust the ventilation volume. It is highly flexible, and the damping structure in the first frame can ensure that the blade will not bounce back after adjustment, which is stable. In addition, the blade is fixed to two rotating shafts by a snap-fit structure, which makes it easy for staff to clean and replace it. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0025] according to Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this embodiment proposes a ventilated and stable box-type substation, including a box body 2, an eaves 1 at the top of the box body 2, and multiple ventilation windows 3 on the outside of the box body 2.
[0026] When a substation is in operation, the electrical equipment such as transformers inside will generate a lot of heat. Multiple ventilation windows 3 are installed on the outside of the enclosure 2 to form an air convection channel, allowing cold air from the outside to enter and hot air to be discharged, ensuring that the electrical equipment inside the enclosure 2 can operate at a suitable temperature and preventing performance from being affected, lifespan from being shortened, or even failures from being caused by overheating.
[0027] The ventilation window 3 is equipped with multiple tilted blades 4. One end of the blade 4 is equipped with a first rotating shaft 6, which is rotatably connected to the ventilation window 3. The other end of the blade 4 is equipped with a second rotating shaft 8, which is rotatably connected to the ventilation window 3. The blade 4 is detachably connected to the first rotating shaft 6 and the second rotating shaft 8 through a snap-fit structure. The blade 4 is fixed to the first rotating shaft 6 and the second rotating shaft 8 through the snap-fit structure, which facilitates cleaning and replacement by staff.
[0028] A first frame 5 is provided on one side of the ventilation window 3, and a second frame 7 is provided on the other side of the ventilation window 3. Both the first frame 5 and the second frame 7 are fixedly connected to the ventilation window 3. The first frame 5 is provided with a damping structure to increase the rotational resistance of the first rotating shaft 6, and the second frame 7 is provided with a connecting rod structure to make each second rotating shaft 8 rotate in coordination.
[0029] The blade 4 is rotatably mounted inside the ventilation window 3 via the first rotating shaft 6 and the second rotating shaft 8, which can prevent rainwater and dust from directly entering the box. When the blade 4 is turned, the linkage structure in the second frame 7 will drive each of the second rotating shafts 8 to rotate in tandem. The other blades 4 in the ventilation window 3 will adjust their opening and closing angles at the same time, thereby controlling the ventilation area of the window and adjusting the ventilation volume. It has high flexibility. The damping structure in the first frame 5 can increase the damping of the first rotating shaft 6 when it rotates from the other side of the blade 4, ensuring that the blade 4 will not bounce back after adjustment, and has better stability.
[0030] It should be noted that all blades 4 have the same tilt angle. After the blades 4 are turned, they will rotate synchronously with the help of the linkage structure. Since the tilt angles of all blades 4 are the same, the blades 4 will not collide with the adjacent blades 4 when they rotate.
[0031] Regarding damping structures:
[0032] The damping structure includes a rubber ring 18 and a second spring 17 disposed within the first frame 5. The rubber ring 18 is fitted around the outside of the first rotating shaft 6 and is slidably connected to the first rotating shaft 6. One side of the rubber ring 18 contacts the outer wall of the vent 3, and the other side of the rubber ring 18 is fixedly connected to the second spring 17. The end of the second spring 17 away from the rubber ring 18 is fixedly connected to the first rotating shaft 6. The end of the second spring 17 is fixed to the first rotating shaft 6. With the support of the second spring 17, the rubber ring 18 is in contact with the outer wall of the vent 3, increasing the friction between the rubber ring 18 and the vent 3. When the blade 4 is lifted upward, the blade 4 will not fall back under the action of friction.
[0033] Regarding the linkage structure:
[0034] The linkage structure includes a connecting plate 15 and a pull rod 16 disposed within the second frame 7. One end of the connecting plate 15 is fixedly connected to the end of the second rotating shaft 8 away from the blade 4, and the other end of each connecting plate 15 is hinged to the pull rod 16 via a cylindrical pin. When one of the second rotating shafts 8 rotates, the second rotating shaft 8 pulls the pull rod 16 through the connecting plate 15, and then synchronously pulls each blade 4 through the other connecting plates 15.
[0035] Regarding the snap-fit structure:
[0036] The snap-fit structure includes a mounting block 9, which is fixedly connected to the facing sides of the first rotating shaft 6 and the second rotating shaft 8. A slot 10 is provided at one end of the mounting block 9 near the blade 4. Both ends of the blade 4 are inserted into the slot 10, and the blade 4 is slidably connected to the slot 10. An elastic locking pin is provided inside the slot 10 to secure the blade 4. During installation, the left and right ends of the blade 4 are aligned with the slots 10 at the ends of the mounting block 9, and then simultaneously inserted into the two slots 10 for assembly. After insertion, the elastic locking pin locks the blade 4 in place.
[0037] It is worth explaining in detail that the elastic locking pin includes a pin groove 11 formed inside the slot 10, a pin body 13 is provided in the pin groove 11, the pin body 13 is slidably connected to the pin groove 11, and the pin body 13 is movably engaged with a pin hole formed on the outside of the blade plate 4. A first spring 14 is provided in the pin groove 11 to support the pin body 13, and the first spring 14 is fixedly connected to the pin body 13. An adjustment device is provided on the outside of the mounting block 9 to adjust the supporting force of the first spring 14. When the blade plate 4 is inserted into the slot 10, under the support of the first spring 14 in the pin groove 11, the pin body 13 will pop out from the pin groove 11 into the slot 10 until it is engaged in the pin hole formed on the outside of the blade plate 4. The pin body 13 limits the blade plate 4 by engaging with the pin.
[0038] To prevent the first spring 14 from loosening due to prolonged use, the adjustment device includes an adjusting bolt 12. The adjusting bolt 12 is mounted on the outside of the mounting block 9, screwed into the pin groove 11, and threadedly connected to it. A rotating ring is located at the end of the first spring 14 furthest from the pin body 13. The rotating ring is fixedly connected to the first spring 14 and rotatably connected to the adjusting bolt 12. When the pin body 13 becomes loose, the adjusting bolt 12 can be rotated and screwed into the pin groove 11. The adjusting bolt 12 will compress the first spring 14, increasing the elastic support force of the first spring 14 on the pin body 13, ensuring a stable fit between the pin body 13 and the blade 4.
[0039] How this application works:
[0040] The blade 4 is rotatably mounted inside the ventilation window 3 via the first rotating shaft 6 and the second rotating shaft 8, preventing rainwater and dust from directly entering the chamber. When the blade 4 is moved, the linkage structure within the second frame 7 drives each of the second rotating shafts 8 to rotate in tandem. Simultaneously, the other blades 4 within the ventilation window 3 adjust their opening angles, thereby controlling the ventilation area and regulating the ventilation volume with high flexibility. The damping structure within the first frame 5 increases the damping of the first rotating shaft 6 from the other side of the blade 4, ensuring that the blade 4 does not spring back after adjustment, resulting in better stability. The blade 4 is fixed to the first rotating shaft 6 and the second rotating shaft 8 via a snap-fit structure, facilitating cleaning and replacement by staff.
