Description

Technical Field

[0001] This invention relates to the field of modular substation technology, and more specifically to a prefabricated modular substation with convenient ventilation. Background Technology

[0002] With the rapid development of the power industry, the demand for substation construction is constantly increasing. Traditional substation construction methods suffer from problems such as long construction cycles, serious resource waste, and poor environmental performance. To address these issues, prefabricated modular substations have emerged. These substations utilize factory processing, standardized production, modular assembly, and prefabricated construction concepts, offering advantages such as short construction cycles, high quality standards, and good environmental performance. This type of substation not only improves construction flexibility and site space utilization but also effectively shortens the construction period and reduces project costs.

[0003] For example, CN118315958B discloses a prefabricated modular substation, including a cabin body; a support plate fixedly connected to the bottom of the cabin body; a first wheel groove formed on the bottom of the cabin body; the first wheel groove is used to guide a trolley; and a fixing plate connected to the bottom of the electrical components. When installing the electrical components in the cabin body, the fixing plate at the bottom of the electrical components is placed on the trolley, pushing the trolley to slide in the first wheel groove to the inside of the cabin body, so that the electrical components are placed on the support plate inside the cabin body. The first wheel groove on the bottom of the cabin body is used to guide the trolley, and the trolley holds the fixing components with the fixing plate. The trolley is used to install the electrical components in the cabin body for easy installation. However, this modular substation is not conducive to long-term effective ventilation, and the installation of electrical components by guiding the trolley is prone to damage to the wheels due to compression.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Example 1

[0051] Please see Figures 1-14 As shown, the present invention is a prefabricated cabin substation with convenient ventilation, including a ventilation component 5. The ventilation component 5 is installed inside the cabin roof 2 and is used to ventilate the cabin 1.

[0052] Cleaning component 6, which consists of four sets arranged around the ventilation component 5, is used to clean the filter screen 504 in the ventilation component 5.

[0053] In this invention, preferably, the ventilation component 5 includes a ventilation channel 500 installed inside the cabin roof 2, and a large fan 501 is fixedly installed in the middle of the ventilation channel 500;

[0054] Small fan 502, two sets of small fan 502 are provided and installed on both sides of the ventilation channel 500 respectively;

[0055] Connecting frame 503, two sets of connecting frame 503 are provided and both slide on both sides of the ventilation channel 500, and filter screen 504 is placed inside the connecting frame 503;

[0056] Spring 506 is fixedly connected to a groove in the connecting frame 503 on one side, and a limiting plate 505 is fixedly connected to the other side of the spring 506, and the limiting plate 505 is slidably connected to one side of the connecting frame 503.

[0057] It should be noted that the limiting plate 505 effectively prevents the filter 504 from detaching from the connecting frame 503, and the ventilation channel 500 is hollow to facilitate airflow.

[0058] In this invention, preferably, the cleaning component 6 includes a second sliding block 609 that moves through a groove opened in the ventilation channel 500. Both ends of one side of the second sliding block 609 are fixedly connected to a second spring 602, and the second spring 602 is fixedly installed in the groove opened in the ventilation channel 500.

[0059] Connecting block 603 is fixed to one side of sliding block 2 609. A moving rod 604 is slidably connected inside the connecting block 603. A limiting post 1 605 is fixed inside the connecting block 603. The moving rod 604 slides on the limiting post 1 605, and a spring 3 606 is sleeved on the limiting post 1 605.

[0060] An electric actuator 600 is fixedly connected to the ventilation channel 500, and a push column 601 is fixedly connected to the output end of the electric actuator 600.

[0061] Positioning block 608 is fixed to the inside of electric push rod 600;

[0062] Connecting rod 607, one side of which is fixed to connecting block 603, and the other side of which is fixed to connecting frame 503.

[0063] It should be noted that one side of the push column 601 is arc-shaped so that the push column 601 can slide across the top of the positioning block 608 after pushing the moving rod 604.

[0064] In this invention, preferably, one side of the moving rod 604 and the positioning block 608 are both arranged in a semi-triangular shape, and one side of the moving rod 604 and the positioning block 608 can overlap when they are connected.

[0065] It should be noted that when one side of the moving rod 604 is connected to the positioning block 608, the inclined surface is in contact. The inclined surface of the moving rod 604 can move downward along the inclined surface of the positioning block 608, thereby causing the pushing column 601 to slide over the positioning block 608.

[0066] In this invention, preferably, two limiting blocks 9 are fixedly connected to the inner side of the cabin roof 2, and a motor 10 is fixedly connected to one side of one of the limiting blocks 9. At the same time, a threaded column 12 is fixedly connected to the output end of the motor 10, and a movable plate 11 is threadedly connected to the surface of the threaded column 12. The movable plate 11 slides through a groove opened in the cabin roof 2. A baffle 13 is fixedly connected to one side of the movable plate 11, and the baffle 13 is slidably connected inside the cabin roof 2. The threaded column 12 is movably connected to the middle of the two limiting blocks 9.

[0067] It should be noted that the area of ​​the baffle 13 is larger than the area of ​​the exposed large fan 501 on the roof 2, so that the baffle 13 can completely cover the exposed surface of the roof 2.

[0068] During implementation, when ventilation is required, motor 210 is installed. The output end of motor 210 rotates the threaded column 12 along the middle of the two limit blocks 9. The rotation of the threaded column 12 causes the moving plate 11 to move along the sliding groove opened between the threaded column 12 and the cabin roof 2. The moving plate 11, carrying the threaded column 12, moves along the cabin roof 2, thus ensuring that the large fan 501 is unobstructed. By controlling the large fan 501 and the two sets of small fans 502, the air in the cabin 1 is ventilated. After ventilation is completed, the filter screen 504 is in place. Dust easily accumulates at air vents during prolonged use, affecting ventilation. An electric push rod 600 is installed. The electric push rod 600 pulls the push column 601 backward, which in turn pushes the moving rod 604 and connecting block 603. The connecting block 603, along with the connecting rod 607, connecting frame 503, filter screen 504, and limiting plate 505, moves backward, compressing the second spring 602. When the inclined surface of the moving rod 604 contacts the inclined surface of the positioning block 608, the moving rod 604 moves along the path pushed by the push column 601. The limiting post 605 moves downward, thus pressing the spring 606. When the inclined surface of the moving rod 604 is fully engaged with the inclined surface of the positioning block 608, the pushing post 601 passes over the positioning block 608. The moving rod 604 has no pushing force and, through the counter-pushing force of the spring 602, propels the connecting block 603, connecting rod 607, connecting frame 503, filter screen 504, and limiting plate 505 forward. This causes the dust on the filter screen 504 to fall off after being pushed and ejected. Pressing the limiting plate 505... When spring 506 is compressed, limit plate 505 moves into connecting frame 503, pulling filter screen 504, making filter screen 504 easier to disassemble. After ventilation, it is easier to clean filter screen 504 in ventilation assembly 5, effectively preventing filter screen 504 from accumulating a lot of dust and affecting ventilation effect. It can effectively maintain the filtration effect of filter screen 504 during ventilation, and filter screen 504 is easier to disassemble and clean, effectively maintaining the air quality inside cabin 1.

[0069] Example 2

[0070] Preferably, the present invention also includes a cabin 1, two slide rails 7 are installed inside the cabin 1, and an installation limiting component 8 is slidably installed on the slide rails 7. A cooling component 3 is installed on one side of the cabin 1, and a blowing component 4 is installed inside the cabin 1.

[0071] It should be noted that doors are installed on both sides of the cabin 1, and each door is equipped with a pull handle to facilitate entry into the cabin 1.

[0072] In this invention, preferably, the installation limiting component 8 includes a slider 805 that slides within the slide rail 7. Limiting posts 810 are fixedly connected to the slide grooves on both sides of the slider 805, and a sliding plate 809 is slidably connected to the limiting posts 810. Meanwhile, a lifting block 806 is fixedly connected to one side of the sliding plate 809, and the lifting block 806 is slidably connected to one side of the slider 805.

[0073] Telescopic column 807, one side of telescopic column 807 is fixed inside slider 805, the other side of telescopic column 807 is fixed to the bottom of lifting block 806, and spring 808 is sleeved on telescopic column 807.

[0074] A connecting plate 800 is fixed to the top of the lifting block 806. Threaded screws 803 are movably installed on the middle of both sides of the connecting plate 800, and guide blocks 801 are threadedly connected to the surface of the threaded screws 803. Meanwhile, a docking plate 802 is fixedly connected to the guide blocks 801.

[0075] Knob 804 is fixed to one side of the threaded screw 803;

[0076] Limit pin 811 is movably installed on one side of connecting plate 800. Limit pin 811 is used for connection and limitation with the interior of cabin 1.

[0077] It should be noted that its slide rail 7 extends to the outside of the cabin 1, and the cabin 1 is provided with multiple sets of connecting grooves to facilitate connection with the limit pin 811 for positioning. The docking plate 802 is provided with mounting holes to facilitate secure connection with the power station box by bolts. The two mounting limit components 8 are grouped together to facilitate adjustment of the distance between them.

[0078] In this invention, preferably, the guide block 801 moves through the grooves opened on both sides of the connecting plate 800, and the threaded screw 803 is installed in the grooves opened in the connecting plate 800.

[0079] In the implementation process, firstly, the two installation limiting components 8 are slidably installed from the end of the slide rail 7 extending to the outside of the cabin 1 via the slider 805. The distance between the two installation limiting components 8 is adjusted. The power station box to be installed is then suspended on the four docking plates 802 using an external lifting device. The knob 804 is rotated, causing the threaded screw 803 to rotate. The rotation of the threaded screw 803 moves the guide block 801 inward along the threaded screw 803 and the slide groove. The guide block 801 moves the docking plate 802 inward, making the docking plate 802 fit more closely to the edges and corners of the power station box. The lifting device is then released, allowing the power station box to fall completely onto the docking plate 802. The power station box is then fixed onto the docking plate 802 through the connecting holes on the docking plate 802. When the power station box falls onto the docking plate 802, significant pressure is generated, causing the docking plate 802 to... 2. The guide block 801 and the connecting plate 800 are pressed together, and the connecting plate 800 presses the lifting block 806. The lifting block 806 moves downward along the limit post 810 through the sliding plates 809 on both sides, and is then buffered by the action of the telescopic post 807 and the spring 808. The power station box is pushed so that it moves into the cabin 1 along the slide rail 7 through the slider 805. The limit pin 811 is placed in the connecting groove in the cabin 1 through the connecting plate 800 for positioning. This makes it easier to install the power station box in the cabin 1, avoiding the inconvenience of installation due to the small internal space of the cabin 1. It can also be adjusted according to the size of the power station box to ensure the stability during installation. After the power station box is installed, it can be buffered and depressurized, which can effectively prevent the power station box from being too heavy and causing the cabin 1 to collapse. This improves the convenience of installing the power station box in the cabin 1.

[0080] Example 3

[0081] In this invention, preferably, the refrigeration component 3 includes a gas storage tank 300 for storing gas. The gas storage tank 300 is fixed to one side of the outside of the cabin 1. A cooler 301 is installed on the gas storage tank 300. A delivery pump 302 is installed on one side of the gas storage tank 300, and the output end of the delivery pump 302 is connected to a transmission pipe 303. At the same time, the other side of the transmission pipe 303 is connected to the interior of the gas storage tank 300.

[0082] It should be noted that the refrigerator 301 is equipped with a controller (not shown) that can control the temperature of the refrigerator 301. Half of its transmission pipe 303 is located inside the chamber 1, and the other half of the transmission pipe 303 is exposed outside the chamber 1.

[0083] In this invention, preferably, the blowing assembly 4 includes a sliding block 402 that moves through a groove opened in the chamber 1, a pin block 403 is engaged on the sliding block 402, and a blowing assembly 404 is fixedly connected to one side of the pin block 403.

[0084] It should be noted that a blower is installed on the blower assembly 404.

[0085] Motor 400 is fixedly installed in the slide groove opened in the cabin 1. The output end of motor 400 is fixedly connected to a reciprocating lead screw 401, and the surface of the reciprocating lead screw 401 is threadedly connected to a sliding block 402.

[0086] In the implementation process, the controller controls the cooler 301, which cools the interior of the gas storage tank 300. A transfer pump 302 transports the cold air from inside the gas storage tank 300 through a transmission pipe 303. This cold air passes through the interior of the cabin 1, cooling its interior, and then returns to the gas storage tank 300, repeating this process. A blowing assembly 404 circulates the cold air from the transmission pipe 303 through the cabin 1 to cool the power station box, achieving the desired cooling effect. The effect is achieved by setting up a motor 400, whose output end drives the reciprocating screw 401 to rotate. The rotation of the reciprocating screw 401 causes the sliding block 402 to move back and forth along the sliding groove opened in the compartment 1. The sliding block 402 drives the blowing assembly 404 to move back and forth, which in turn causes the blowing assembly 404 to move back and forth along the direction of the transmission pipe 303. This allows the cold airflow generated on the surface of the transmission pipe 303 to be blown back and forth towards the power station box, so that each power station box can receive uniform blowing, thereby improving the cooling effect.

[0087] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
