Description

Technical Field

[0001] This invention relates to the field of prefabricated cabin technology, specifically to a prefabricated cabin that reduces energy consumption. Background Technology

[0002] Prefabricated modules are an important embodiment of new technologies, materials, and equipment in smart substations. They consist of a prefabricated module body, secondary equipment cabinets, and auxiliary facilities. Manufacturing, assembly, wiring, and commissioning are completed in the factory, and the modules are transported to the construction site as a whole, where they are installed on the foundation. Prefabricated modules and their internal secondary equipment allow for complete integration of the secondary equipment by the manufacturer, achieving factory processing, reducing on-site secondary wiring, design, construction, and commissioning workload, simplifying maintenance, and shortening the construction cycle. This effectively supports the rapid construction of the power grid. Existing prefabricated modules can effectively improve the wind and earthquake resistance of the modules.

[0003] For example, Chinese invention patent CN106836878B discloses a prefabricated cabin installation structure to reduce the amount of civil engineering work during the installation process and improve the wind and earthquake resistance of the prefabricated cabin. This invention also provides a prefabricated cabin. The prefabricated cabin installation structure includes a prefabricated cabin, which comprises a cabin body and a base. The structure also includes sleeper connectors and counterweight sleepers arranged side-by-side at intervals. The bottom of the base is detachably connected to the counterweight sleepers via sleeper connectors and supported on the counterweight sleepers. During on-site construction, the counterweight sleepers are laid as required. The base of the prefabricated cabin is detachably connected to the counterweight sleepers via sleeper connectors. The sleeper connectors located between the base and the counterweight sleepers also provide support. The gaps around and between the counterweight sleepers are filled with granite gravel, thus completing the installation. This significantly reduces the amount of on-site civil engineering work, and the counterweight sleepers act as a self-weighting foundation for the prefabricated cabin, effectively improving its wind and earthquake resistance.

[0004] For example, Chinese invention patent CN108493782B discloses a prefabricated cabin, which includes: a cable tray located below the floor of the prefabricated cabin for collecting wires in the prefabricated cabin; a first grounding structure located below the floor of the prefabricated cabin and distributed corresponding to the positions of at least two devices in the prefabricated cabin, for grounding the low-voltage ground wires of at least two devices in the cable tray; and a second grounding structure located below the floor of the prefabricated cabin and distributed corresponding to the positions of at least two devices in the prefabricated cabin, for grounding the high-voltage ground wires of at least two devices in the cable tray. Through the above method, the present invention simplifies the grounding operation.

[0005] The existing prefabricated modules still have the following problems;

[0006] 1. The various components are fixed together with screws, which makes the installation process cumbersome and inconvenient to assemble the components.

[0007] 2. After heat dissipation, the high-temperature gas enters the environment and is then drawn into the refrigeration unit through the gas pipe, increasing the workload of the refrigeration unit and thus increasing its energy consumption. Therefore, we propose a prefabricated cabin to reduce energy consumption in order to solve the problems mentioned above. Summary of the Invention

[0008] The purpose of this invention is to provide a prefabricated cabin with reduced energy consumption, in order to solve the problems mentioned in the background art, where the various components of the existing prefabricated cabin are fixedly connected by screws, making the installation operation cumbersome and inconvenient to assemble the various components. After heat dissipation, the high-temperature gas enters the environment and is then drawn into the refrigeration unit by the gas pipe, increasing the workload of the refrigeration unit and thus increasing its energy consumption.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated cabin for reducing energy consumption, comprising a base, an air pump, a refrigeration unit, and a maintenance door:

[0011] A heat-insulating support is fixed on the top of the base;

[0012] A heat-insulating enclosure is provided above the heat-insulating receiving seat. A connecting plate is fixed to the lower surface of the heat-insulating enclosure.

The refrigeration unit is fixed to the left side of the heat-insulating enclosure. A second air pipe is connected to the bottom pipe of the refrigeration unit through a flange. A third air pipe is fixed to the output end of the air pump. Conveying pipes are fixed to both the front and rear ends of the heat-insulating enclosure. Reinforcing rods are fixed to the outer side of the conveying pipes. An air outlet is opened inside the heat-insulating enclosure. An air outlet pipe passes through the right end of the heat-insulating enclosure. A fourth air pipe is fixedly connected to the bottom end of the air outlet pipe through a flange.

[0013] A heat-insulating top cover is provided above the heat-insulating enclosure, and a hollow box is fixed on the lower surface of the heat-insulating top cover. Both the heat-insulating support and the hollow box are equipped with limiting mechanisms, and both the heat-insulating support and the hollow box are fixed with rectangular plates.

[0014] The insulated enclosure panel has a maintenance door installed on the right end via a hinge.

[0015] By adopting the above technical solution, the rollers and positioning rods facilitate movement and positioning, and the limiting mechanism facilitates the assembly of various parts of the prefabricated cabin. Burying the second and fourth air pipes in the soil can reduce the energy consumption of the refrigeration unit, improve the heat dissipation efficiency of electrical components, and reduce the energy consumption of the refrigeration unit.

[0016] As a preferred embodiment of the present invention, the limiting mechanism includes a servo motor, a toothed roller, a first limiting frame, and a second limiting frame. The heat-insulating receiving seat and the front end of the hollow box are both fixed with servo motors, and the output end of the servo motor is fixed with a toothed roller. The top end of the toothed roller is engaged with the first limiting frame, and the bottom end of the toothed roller is engaged with the second limiting frame.

[0017] By adopting the above technical solution, the limiting mechanism facilitates a stable connection of the various components.

[0018] As a preferred embodiment of the present invention, the first limiting frame and the second limiting frame form a sliding structure with the rectangular plate.

[0019] By adopting the above technical solution, the first limiting frame and the second limiting frame can slide stably.

[0020] As a preferred embodiment of the present invention, the connection between the first limiting frame and the second limiting frame and the connecting plate, as well as the connection between the first limiting frame and the second limiting frame and the heat insulation enclosure plate, are all snap-fit ​​connections.

[0021] By adopting the above technical solution, it is convenient to combine the first limiting frame and the connecting plate, as well as the second limiting frame and the heat insulation enclosure plate, and to facilitate the assembly of each component.

[0022] As a preferred embodiment of the present invention, both the second and fourth trachea are buried in the soil.

[0023] By adopting the above technical solution, the second and fourth air pipes are buried in the soil to facilitate heat dissipation.

[0024] As a preferred embodiment of the present invention, the wear-resistant roller has equally spaced circular holes inside, and the wear-resistant roller is confined within the base by a positioning rod.

[0025] By adopting the above technical solution, the wear-resistant rollers are positioned using positioning rods, which facilitates the definition of the prefabricated compartment.

[0026] As a preferred embodiment of the present invention, the third air pipe is fixedly connected to the delivery pipe, and the delivery pipe has a zigzag structure, and the holes on the delivery pipe are aligned with the air outlet.

[0027] By adopting the above technical solution, the low-temperature gas is evenly distributed in the prefabricated cabin by using the evenly arranged gas outlets.

[0028] As a preferred embodiment of the present invention, the connection between the connecting plate and the heat insulation support is a snap-fit ​​connection.

[0029] By adopting the above technical solution, it is convenient to combine the connecting plate and the heat insulation support.

[0030] Compared with the prior art, the beneficial effects of the present invention are: the energy-saving prefabricated cabin is easy to move and position by setting rollers and positioning rods, and the various parts of the prefabricated cabin can be easily combined by using a limiting mechanism. Burying the second and fourth air pipes in the soil can reduce the energy consumption of the refrigeration unit, improve the heat dissipation efficiency of electrical components, and reduce the energy consumption of the refrigeration unit.

[0031] 1. It is equipped with a base, wear-resistant rollers and positioning rods. The wear-resistant rollers are rotatably installed in the base. The wear-resistant rollers facilitate the movement of the prefabricated cabin. The positioning rod is inserted into the wear-resistant rollers to position the prefabricated cabin.

[0032] 2. It is equipped with a heat-insulating receiving seat, a heat-insulating enclosure plate and a heat-insulating top cover. The servo motor inside the limiting mechanism drives the first limiting frame and the second limiting frame to move through the toothed roller, controlling the position of the first limiting frame and the second limiting frame relative to the connecting plate and the heat-insulating enclosure plate. The limiting mechanism fixes the heat-insulating receiving seat to the heat-insulating enclosure plate and the heat-insulating enclosure plate to the heat-insulating top cover, which facilitates the assembly and disassembly of the prefabricated cabin.

[0033] 3. A second and a fourth gas pipe are provided. When gas enters the second gas pipe, the gas temperature is reduced by the soil because the second gas pipe is buried in the soil. When gas flows out of the fourth gas pipe, the gas temperature is reduced by the soil because the fourth gas pipe is buried in the soil. This prevents the high-temperature air after heat exchange from entering the environment and increasing the workload of the refrigeration unit. Burying the second and fourth gas pipes in the soil can reduce the energy consumption of the refrigeration unit.

[0034] 4. It is equipped with a heat insulation enclosure, a conveying pipe and an air outlet. Low-temperature gas flows from the conveying pipe and the air outlet into the interior of the heat insulation enclosure, so that the low-temperature gas is evenly distributed inside the heat insulation enclosure, thereby improving the heat dissipation efficiency of electrical components.

[0043] 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.

[0044] Please see Figure 1-7 The present invention provides a technical solution: a prefabricated cabin with reduced energy consumption, comprising a base 1, wear-resistant rollers 2, positioning rods 3, heat-insulating support seats 4, heat-insulating enclosure plates 5, connecting plates 6, an air pump 7, a first air pipe 8, a refrigeration unit 9, a second air pipe 10, a third air pipe 11, a conveying pipe 12, a reinforcing rod 13, an air outlet 14, an air outlet pipe 15, a fourth air pipe 16, a heat-insulating top cover 17, a hollow box 18, a servo motor 19, a toothed roller 20, a first limiting frame 21, a second limiting frame 22, a rectangular plate 23, and a maintenance door 24. The wear-resistant rollers 2 are rotatably connected at equal intervals inside the base 1, and the positioning rods 3 are provided at the outer ends of the wear-resistant rollers 2.

[0045] A heat-insulating support seat 4 is fixed on the top of the base 1;

[0046] A heat insulation enclosure plate 5 is installed above the heat insulation receiving seat 4. A connecting plate 6 is fixed to the lower surface of the heat insulation enclosure plate 5. A vacuum pump 7 is fixed to the left side of the heat insulation enclosure plate 5. A first air pipe 8 is fixed to the input end of the vacuum pump 7. A refrigeration unit 9 is installed below the vacuum pump 7. The refrigeration unit 9 is fixed to the left side of the heat insulation enclosure plate 5. A second air pipe 10 is connected to the pipe at the bottom end of the refrigeration unit 9 through a flange. A third air pipe 11 is fixed to the output end of the vacuum pump 7. A conveying pipe 12 is fixed to both the front and rear ends of the heat insulation enclosure plate 5. A reinforcing rod 13 is fixed to the outer side of the conveying pipe 12. An air outlet 14 is opened inside the heat insulation enclosure plate 5. An air outlet pipe 15 passes through the right end of the heat insulation enclosure plate 5. A fourth air pipe 16 is fixedly connected to the bottom end of the air outlet pipe 15 through a flange.

[0047] A heat insulation top cover 17 is provided above the heat insulation enclosure 5, and a hollow box 18 is fixed on the lower surface of the heat insulation top cover 17. Both the heat insulation support 4 and the hollow box 18 are equipped with limiting mechanisms, and both the heat insulation support 4 and the hollow box 18 are fixed with rectangular plates 23.

[0048] The heat-insulating enclosure panel 5 is fitted with a maintenance door 24 on the right end via a hinge;

[0049] like Figure 1 and Figure 2 In the middle, the limiting mechanism includes a servo motor 19, a toothed roller 20, a first limiting frame 21 and a second limiting frame 22. The servo motor 19 is fixed inside the front end of the heat insulation receiving seat 4 and the hollow box 18, and the toothed roller 20 is fixed at the output end of the servo motor 19. The top end of the toothed roller 20 is engaged with the first limiting frame 21, and the bottom end of the toothed roller 20 is engaged with the second limiting frame 22. The limiting mechanism facilitates the stable connection of various components.

[0050] like Figure 1 In the middle, the first limiting frame 21 and the second limiting frame 22 form a sliding structure with the rectangular plate 23. The rectangular plate 23 supports the first limiting frame 21 and the second limiting frame 22, so that the first limiting frame 21 and the second limiting frame 22 can slide stably.

[0051] like Figure 1 In the process, the connection between the first limiting frame 21 and the second limiting frame 22 and the connecting plate 6, as well as the connection between the first limiting frame 21 and the second limiting frame 22 and the heat insulation enclosure plate 5, are all snap-fit ​​connections, which facilitates the combination of the first limiting frame 21 and the connecting plate 6, and the second limiting frame 22 and the heat insulation enclosure plate 5, and makes it easy to assemble each component.

[0052] like Figure 1 In the middle, the second trachea 10 and the fourth trachea 16 are both buried in the soil to facilitate heat dissipation.

[0053] like Figure 1 and Figure 6In the middle, the wear-resistant roller 2 has round holes at equal intervals inside, and the wear-resistant roller 2 is limited in the base 1 by the positioning rod 3. The positioning rod 3 is used to position the wear-resistant roller 2, which is convenient for limiting the prefabricated compartment.

[0054] like Figure 1 and Figure 5 In the middle, the third gas pipe 11 is fixedly connected to the delivery pipe 12, and the delivery pipe 12 has a zigzag structure. The holes on the delivery pipe 12 are aligned with the gas outlet 14. The uniformly arranged gas outlets 14 make the low temperature gas evenly distributed in the prefabricated chamber.

[0055] like Figure 1 and Figure 7 In the middle, the connection method between the connecting plate 6 and the heat insulation support 4 is a snap-fit ​​connection, which facilitates the combination of the connecting plate 6 and the heat insulation support 4.

[0056] During assembly, the worker places the heat insulation enclosure 5 on the heat insulation support 4, and the connecting plate 6 on the heat insulation enclosure 5 is inserted into the heat insulation support 4. The servo motor 19 of the internal limiting structure of the heat insulation support 4 is opened, and the servo motor 19 drives the toothed roller 20 to rotate counterclockwise. As a result, the first limiting frame 21, which is engaged with the toothed roller 20, moves to the left, and the second limiting frame 22, which is engaged with the toothed roller 20, moves to the right. This causes the first limiting frame 21 and the second limiting frame 22 to be inserted into the connecting plate 6, thereby fixing the heat insulation enclosure 5 on the heat insulation support 4.

[0057] After the staff installs the electrical components on the inside of the heat insulation enclosure 5, they clip the heat insulation top cover 17 onto the top of the heat insulation enclosure 5, open the servo motor 19 inside the hollow box 18, and the servo motor 19 drives the toothed roller 20 to rotate counterclockwise. As the toothed roller 20 rotates counterclockwise, the first limiting frame 21 moves to the left and the second limiting frame 22 moves to the right. That is, the rotation of the servo motor 19 and the toothed roller 20 drives the first limiting frame 21 and the second limiting frame 22 to move outward, so that the first limiting frame 21 and the second limiting frame 22 are clipped into the inside top of the heat insulation enclosure 5, thereby limiting the heat insulation top cover 17 to the heat insulation enclosure 5.

[0058] like Figure 1 As shown, wear-resistant rollers 2 are rotatably installed at equal intervals inside the base 1, which push the energy-saving prefabricated cabin. Under the action of the wear-resistant rollers 2, the energy-saving prefabricated cabin moves. When positioning is required, the wear-resistant rollers 2 have round holes at equal angles inside. The positioning rod 3 is inserted through the base 1 into the corresponding round hole of the wear-resistant roller 2 to limit the wear-resistant roller 2, thereby positioning the energy-saving prefabricated cabin.

[0059] The second air pipe 10 and the fourth air pipe 16 are connected to the refrigeration unit 9 and the air outlet pipe 15 via flanges. After the prefabricated cabin is moved to its destination, a foundation pit is dug on the side of the prefabricated cabin, and then the second air pipe 10 and the fourth air pipe 16 are buried in the soil. When it is necessary to dissipate heat for the electrical components inside the heat insulation enclosure 5, the air pump 7 is turned on. Under the action of the air pump 7, the outside air enters the interior of the refrigeration unit 9 through the second air pipe 10, and then flows through the first air pipe 8 to the air pump 7 and the third air pipe 11. It flows through the third air pipe 11 to the delivery pipe 12, and then the low-temperature gas flows out from the air outlet 14. The air after heat exchange flows from the air outlet pipe 15 to the fourth air pipe 16. After being cooled by the soil, the air flows back into the air. The air is cooled by the soil, which prevents the high-temperature air after heat exchange from entering the environment and reduces the energy consumption of the refrigeration unit 9. When the air flows inside the second air pipe 10, it is cooled by the soil, which reduces the burden on the refrigeration unit 9.

[0060] When electrical components need to be repaired, open the maintenance door 24 and enter the installation environment consisting of the heat-insulating support 4, the heat-insulating enclosure 5, and the heat-insulating top cover 17 to perform maintenance on the electrical components.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
