Detailed implementation manners

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0050] Embodiment 1

[0051] Please refer to Figures 1 - 14 as shown. The present invention is a prefabricated cabin type substation convenient for ventilation, including a ventilation component 5. The ventilation component 5 is installed inside the cabin ceiling 2, and the ventilation component 5 is used for ventilating and replacing the air in the cabin body 1;

[0052] a cleaning component 6. There are four groups of cleaning components 6 and they are arranged around the inside of the ventilation component 5. The cleaning component 6 is used for cleaning the filter screen 504 in the ventilation component 5.

[0053] In the present invention, preferably, the ventilation assembly 5 includes a ventilation passage 500 installed inside the cabin ceiling 2, and a large fan 501 is fixedly installed in the middle of the ventilation passage 500;

[0054] There are two small fans 502, which are respectively installed on both sides inside the ventilation passage 500;

[0055] There are two connection frames 503, both of which slide on both sides inside the ventilation passage 500, and a filter net 504 is placed inside the connection frame 503;

[0056] A first spring 506, one side of the first spring 506 is fixedly connected to a groove formed in the connection frame 503, the other side of the first spring 506 is fixedly connected to a limiting plate 505, and the limiting plate 505 is slidably connected to one side of the connection frame 503.

[0057] It should be noted that the setting of the limiting plate 505 can effectively prevent the filter net 504 from detaching from the connection frame 503, and the ventilation passage 500 is hollow to facilitate air flow.

[0058] In the present invention, preferably, the cleaning assembly 6 includes a second sliding block 609 that moves through a chute formed in the ventilation passage 500. Both ends on one side of the second sliding block 609 are fixedly connected to second springs 602, and the second springs 602 are fixedly installed in the chute formed in the ventilation passage 500;

[0059] A connection block 603 is fixedly connected to one side of the second sliding block 609. A moving rod 604 is slidably connected inside the connection block 603. A first limiting post 605 is fixedly connected inside the connection block 603. The moving rod 604 slides on the first limiting post 605, and a third spring 606 is sleeved on the first limiting post 605;

[0060] An electric push rod 600 is fixedly connected inside the ventilation passage 500, and a push column 601 is fixedly connected to the output end of the electric push rod 600;

[0061] A positioning block 608 is fixedly connected to the inner side of the electric push rod 600;

[0062] A connecting rod 607, one side of the connecting rod 607 is fixedly connected to the connection block 603, and the other side of the connecting rod 607 is fixedly connected to the connection 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 the present invention, preferably, one side of the moving rod 604 and the positioning block 608 are both semi-triangularly arranged, and one side of the moving rod 604 can be overlapped with the positioning block 608 when they are butted.

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

[0066] In the present invention, preferably, two limiting blocks 9 are fixedly connected to the inner side of the cabin ceiling 2, and a second motor 10 is fixedly connected to one side of one of the limiting blocks 9. At the same time, the output end of the second motor 10 is fixedly connected to a threaded column 12, and a moving plate 11 is threadedly connected to the surface of the threaded column 12. The moving plate 11 slides through a sliding groove opened in the cabin ceiling 2. A baffle 13 is fixedly connected to one side of the moving plate 11, and the baffle 13 is slidably connected in the cabin ceiling 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 cabin ceiling 2 exposing the large blower 501, so that the baffle 13 can completely cover the exposed surface of the cabin ceiling 2.

[0068] Implementation process: When ventilation is required, the second motor 10 is set. The output end of the second motor 10 drives the threaded column 12 to rotate 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 threaded column 12 and the chute opened in the cabin ceiling 2. The moving plate 11 drives the threaded column 12 to move along the cabin ceiling 2, so that the large air blower 501 is unobstructed. The air in the cabin 1 is ventilated and exchanged by controlling the large air blower 501 and the two groups of small air blowers 502. After ventilation is completed, since the filter screen 504 is prone to dust accumulation at the air outlet during long-term use, which affects the ventilation effect, the electric push rod 600 is set. The electric push rod 600 drives the push column 601 to pull backward. The push column 601 pushes the moving rod 604 and the connecting block 603. The connecting block 603 drives the connecting rod 607, the connecting frame 503, the filter screen 504, and the limiting plate 505 to move backward and squeeze 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 downward along the first limiting column 605 under the push of the push column 601 and further squeezes the third spring 606. When the inclined surface of the moving rod 604 is completely fitted with the inclined surface of the positioning block 608, the push column 601 passes through above the positioning block 608. The moving rod 604 has no driving force and is elastically ejected forward with the connecting block 603, the connecting rod 607, the connecting frame 503, the filter screen 504, and the limiting plate 505 through the reaction force of the second spring 602, so that the dust on the filter screen 504 falls off after being pushed and ejected. Press the limiting plate 505, and the limiting plate 505 squeezes the first spring 506. The limiting plate 505 moves into the connecting frame 503. Pull the filter screen 504 to make the filter screen 504 easier to disassemble. After ventilation and air exchange in the cabin 1, it is more convenient to clean the filter screen 504 in the ventilation component 5, which can effectively prevent the filter screen 504 from accumulating a large amount of dust and affecting the ventilation effect, can effectively maintain the filtering effect of the filter screen 504 during ventilation, and the filter screen 504 is more convenient to disassemble and clean, and can effectively maintain the air quality of ventilation in the cabin 1.

[0070] In the present invention, preferably, it further includes a cabin 1. Two slide rails 7 are installed in the cabin 1, and an installation limiting component 8 is slidably installed on the slide rails 7. A refrigeration component 3 is installed on one side of the cabin 1, and a blowing component 4 is installed in the cabin 1.

[0071] It should be noted that doors are installed on both sides of the cabin 1, and pulling handles are installed on the doors to facilitate entry into the interior of the cabin 1.

[0072] In the present invention, preferably, the installation limiting component 8 includes a slider 805 that slides within the slide rail 7. Limiting posts II 810 are fixedly connected to the inner sides of the sliding grooves formed on both sides of the slider 805. A sliding plate 809 is slidably connected to the limiting posts II 810. At the same time, 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] A telescopic column 807, one side of the telescopic column 807 is fixedly connected to the inside of the slider 805, the other side of the telescopic column 807 is fixedly connected to the bottom of the lifting block 806, and a spring IV 808 is sleeved on the telescopic column 807;

[0074] A connecting plate 800, the connecting plate 800 is fixedly connected to the top of the lifting block 806. Threaded lead screws 803 are movably installed in the middle of both sides of the connecting plate 800. A guiding block 801 is threadedly connected to the surface of the threaded lead screw 803. At the same time, a docking plate 802 is fixedly connected to the guiding block 801;

[0075] A knob 804, the knob 804 is fixedly connected to one side of the threaded lead screw 803;

[0076] A limit pin 811, the limit pin 811 is movably installed on one side of the connecting plate 800, and the limit pin 811 is used for connecting and limiting with the inside of the cabin body 1.

[0077] It should be noted that the slide rail 7 extends to the outside of the cabin body 1. Multiple connecting grooves are provided inside the cabin body 1 to facilitate connection and positioning with the limit pin 811.

[0079] During the implementation process, first, slide the two installation limiting components 8 along the slide rail 7 at the end outside the cabin body 1 through the sliders 805, adjust the distance between the two installation limiting components 8, suspend the power station box to be installed on the four docking plates 802 through an external lifting tool, rotate the knob 804, the knob 804 drives the threaded lead screw 803 to rotate, the rotation of the threaded lead screw 803 causes the guiding block 801 to move inward along the threaded lead screw 803 and the chute, the guiding block 801 drives the docking plate 802 to move inward, making the docking plate 802 fit more closely to the corners of the power station box, loosen the lifting tool so that the power station box completely falls onto the docking plate 802, and fix and install the power station box on the docking plate 802 through the connection holes on the docking plate 802. When the power station box falls onto the docking plate 802, it generates a large pressure, causing the docking plate 802 to squeeze the guiding block 801 and the connecting plate 800, and the connecting plate 800 squeezes the lifting block 806. The lifting block 806 moves downward along the limiting column two 810 through the sliding plates 809 on both sides and is buffered by the telescopic column 807 and the spring four 808. Push the power station box so that the power station box moves into the cabin body 1 along the slide rail 7 through the slider 805. Insert the limit pin 811 through the connecting plate 800 and place it in the connection slot inside the cabin body 1 for positioning, making it more convenient to install the power station box on the cabin body 1, avoiding inconvenience in installation due to the small internal space of the cabin body 1, and being able to adjust according to the size of the power station box to ensure stability during installation. After the power station box is installed, it can be buffered and decompressed, effectively avoiding the collapse of the inside of the cabin body 1 caused by the overweight of the power station box, thereby improving the convenience of installing the power station box on the cabin body 1.

The delivery pump 302 transports the cold air flow inside the gas storage tank 300 through the transmission pipe 303. When the cold air flow in the transmission pipe 303 passes through the inside of the cabin body 1, it cools the inside of the cabin body 1 and finally returns to the gas storage tank 300 to repeat this process. A blowing row group 404 is provided. The blowing row group 404 blows the cold air passing through the inside of the cabin body 1 by the transmission pipe 303 to the power station box to achieve the effect of cooling. A first motor 400 is provided. The output end of the first motor 400 drives the reciprocating lead screw 401 to rotate. The rotation of the reciprocating lead screw 401 makes the first sliding block 402 reciprocate along the reciprocating lead screw 401 and the chute opened in the cabin body 1. The first sliding block 402 drives the blowing row group 404 to reciprocate, so that the blowing row group 404 reciprocates along the arrangement direction of the transmission pipe 303, enabling the cold air flow generated on the surface of the transmission pipe 303 to reciprocally blow towards the power station box, ensuring that each power station box can be evenly blown, thereby improving the cooling effect.
