Description

Technical Field

[0001] The present invention relates to the technical field of substations, and specifically relates to a box-type substation with a heat dissipation device. Background Art

[0002] A box-type substation is a high-voltage switchgear, a distribution transformer, and a low-voltage distribution device, which are factory prefabricated indoor and outdoor compact distribution equipment arranged in a certain wiring scheme. During the operation of the box-type substation, a relatively high temperature will be generated, so heat dissipation and temperature reduction treatment are required. The Chinese patent with the publication number "CN113097873B" provides a heat dissipation system for a box-type substation. In this application, by setting a heat dissipation area, the fan in the heat dissipation area introduces external air into the frame, and takes out the heat inside the cabinet, so as to achieve the effect of cooling and heat dissipation. However, when the external environmental temperature is relatively high, the cooling and heat dissipation effect is poor. Moreover, the heat dissipation area is provided with structures such as electrical components, which occupy a large amount of space in the box-type substation. At the same time, the existing box-type substations are generally divided into two chambers, and this application cannot dissipate heat from the chamber with a relatively high temperature quickly and centrally, so that the temperature in this chamber remains relatively high. Summary of the Invention

[0003] The purpose of the present invention is to provide a box-type substation with a heat dissipation device to solve the problems raised in the above background art.

[0004] To achieve the above-mentioned invention purpose, the present invention adopts the following technical scheme:

[0005] A box-type substation with a heat dissipation device provided by the present invention includes a box body. The box body is provided with two chambers. A first partition board for separating the two chambers is fixedly connected inside the box body. An installation groove is opened on the first partition board. A distribution mechanism for controlling the passage of gas is fixedly connected in the installation groove. A refrigeration mechanism for refrigeration is fixedly connected to the outer wall of the box body. The output end of the refrigeration mechanism is connected to the distribution mechanism. The output ends of the distribution mechanism located in the two chambers are respectively fixedly connected with a cooling mechanism. The cooling mechanism is wrapped on the electrical components in the two chambers.

[0006] Further, the distribution mechanism includes a fixed pipe fixedly connected in the installation groove. One end of the fixed pipe is fixedly connected with a distribution pipe. Both ends of the distribution pipe penetrate through the first partition plate and extend into the chamber. A first rotating shaft is rotatably connected at the position where the distribution pipe is connected to the fixed pipe. One end of the first rotating shaft extending into the distribution pipe is fixedly connected with a partition block. Symmetrically fixed blocks are fixedly connected to the fixed pipe near the partition block. One end of the first rotating shaft extending outside the distribution pipe is fixedly connected with a connecting rod. One end of the connecting rod away from the first rotating shaft is fixedly connected with a pushing rod. Driving components are fixedly connected to one side of the first partition plate in both chambers, and the driving components are used to drive the pushing rod to move.

[0007] Further, the driving component includes an installation frame fixedly connected to the first partition plate. A sliding groove is formed at the position of the installation frame close to the first partition plate. An airbag is arranged in the installation frame. One end of the airbag close to the pushing rod is fixedly connected with a sliding plate. One end of the sliding plate away from the airbag is fixedly connected with an abutting rod. A limiting plate is fixedly connected to one end of the sliding plate located in the sliding groove. The abutting rod is hinged to the pushing rod.

[0008] Further, the cooling mechanism includes a connecting sleeve fixedly connected to the distribution pipe. One end of the connecting sleeve away from the distribution pipe is fixedly connected with a cooling pipe. A second partition plate is fixedly connected to the cooling pipe along the axial direction. A second rotating shaft is rotatably connected through the connecting sleeve. One end of the second rotating shaft located in the connecting sleeve is fixedly connected with a blocking block. One end of the second rotating shaft extending into the installation frame is fixedly connected with a pushing block. A torsion spring is sleeved on the second rotating shaft. One end of the torsion spring is fixedly connected with the connecting sleeve, and the other end of the torsion spring is fixedly connected with the second rotating shaft.

[0009] Further, the cooling pipe is wrapped on the electrical components in both chambers, and the cooling pipe is divided into two channels by the second partition plate.

[0010] Further, the blocking block is semicircular, and the blocking block is used to close one of the channels of the cooling pipe.

[0011] Further, the side of the pushing block close to the sliding plate is arc-shaped, and the pushing block abuts against the limiting plate.

[0012] Further, the abutting rod is hinged to the pushing rod.

[0013] Further, one end of the fixed pipe extending outside the box body is connected to the refrigeration mechanism.

[0014] Further, a storage cavity is opened at the lower side of the box body. A sponge is arranged in the storage cavity, and the storage cavity is communicated with one end of the cooling pipe away from the connecting sleeve.

[0015] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0016] Through the distribution mechanism provided in the present invention, the low-temperature air generated by the refrigeration mechanism is distributed, so that more low-temperature air flows to the cooling mechanism in the chamber with a relatively higher temperature, enabling the temperature of the electrical components in this chamber to drop faster. At the same time, the distribution mechanism conveys low-temperature air to the cooling mechanism in the chamber with a relatively lower temperature, preventing the electrical components in the chamber with a relatively lower temperature from being unable to dissipate heat, resulting in a continuous increase in the temperature of the electrical components in this chamber;

[0017] The provided cooling mechanism can wrap the electrical components in the two chambers, without occupying too much space in the box-type substation, and can be installed and modified on the original display substation, reducing the production and manufacturing time;

[0018] The provided second partition plate divides the cooling pipe into two channels. When one channel is blocked by the blocking block, the air flow speed in the other channel will be accelerated, and the heat exchange speed with the electrical components will be accelerated, so that the temperature of the electrical components in the chamber with a relatively higher temperature can drop more rapidly.

[0019] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0030] Please refer to Figures 1 to 6 , the present invention provides a box-type substation with a heat dissipation device, including a box body 1. The box body 1 is provided with two chambers. A first partition board 2 for separating the two chambers is fixedly connected inside the box body 1. An installation groove 3 is opened on the first partition board 2. A distribution mechanism 4 for controlling the passage of gas is fixedly connected in the installation groove 3. A refrigeration mechanism 5 for refrigeration is fixedly connected to the outer wall of the box body 1. The output end of the refrigeration mechanism 5 is connected to the distribution mechanism 4. The output ends of the distribution mechanism 4 located in the two chambers are respectively fixedly connected with a cooling mechanism 6. The cooling mechanism 6 is wrapped on the electrical components in the two chambers.

[0031] The provided refrigeration mechanism 5 is used to produce low-temperature air, which flows through the distribution mechanism 4 to the cooling mechanism 6 located in the two chambers of the box body 1. In the initial state, the distribution mechanism 4 evenly distributes the low-temperature air to the cooling mechanism 6 in the two chambers, thereby dissipating heat from the electrical components in the two chambers. Moreover, the cooling mechanism 6 is wrapped on the electrical components in the two chambers, and will not occupy too much space in the box-type substation. It can be retrofitted on the original box-type substation, reducing the corresponding production and manufacturing time. The distribution mechanism 4 can redistribute the low-temperature air when the temperature in one chamber is higher than that in the other chamber, and deliver more low-temperature air to the high-temperature chamber to make it dissipate heat faster.

[0032] Please refer to Figure 3 and Figure 4, the distribution mechanism 4 includes a fixed pipe 7 fixedly connected in the installation groove 3. One end of the fixed pipe 7 is fixedly connected with a distribution pipe 8. Both ends of the distribution pipe 8 penetrate through the first partition plate 2 and extend into the chamber. The position where the distribution pipe 8 is connected to the fixed pipe 7 is rotatably connected with a first rotating shaft 9. One end of the first rotating shaft 9 extending into the distribution pipe 8 is fixedly connected with a partition block 10. Symmetrically fixed to the position of the fixed pipe 7 close to the partition block 10 are limiting blocks 11. One end of the first rotating shaft 9 extending outside the distribution pipe 8 is fixedly connected with a connecting rod 12. One end of the connecting rod 12 far from the first rotating shaft 9 is fixedly connected with a push rod 13. On one side of the first partition plate 2 located in the two chambers, a driving component 14 is fixedly connected. The driving component 14 is used to drive the push rod 13 to move.

[0033] Please refer to Figure Figure 4 and Figure 5 , the driving component 14 includes a mounting frame 15 fixedly connected to the first partition plate 2. A sliding groove 16 is opened at the position of the mounting frame 15 close to the first partition plate 2. An airbag 17 is arranged in the mounting frame 15. One end of the airbag 17 close to the push rod 13 is fixedly connected with a sliding plate 18. One end of the sliding plate 18 far from the airbag 17 is fixedly connected with an abutting rod 19. One end of the sliding plate 18 located in the sliding groove 16 is fixedly connected with a limiting plate 20.

[0034] When the temperature in one of the chambers is relatively high, the airbag 17 in this chamber will expand to a larger volume. The airbag 17 will drive the sliding plate 18 to move. The movement of the sliding plate 18 drives the abutting rod 19 to move. The movement of the abutting rod 19 drives the push rod 13 to rotate around the first rotating shaft 9. The rotation of the push rod 13 drives the first rotating shaft 9 to rotate. The rotation of the first rotating shaft 9 drives the partition block 10 to rotate. The partition block 10 rotates away from the chamber with a relatively high temperature, increasing the space where the fixed pipe 7 and the distribution pipe 8 on the side close to the chamber with a relatively high temperature are connected. Thus, more low-temperature air can flow to the chamber with a higher temperature, thereby quickly dissipating heat from the electrical components therein and preventing damage caused by the continuous increase in the temperature of the electrical components. And when the partition block 10 rotates, the limiting block 11 limits the partition block 10 to prevent the partition block 10 from completely closing the partition block 10 on the side of the chamber with a lower temperature, avoiding the inability of the electrical components in the chamber with a lower temperature to dissipate heat and causing the continuous increase in the temperature of the electrical components in this chamber.

[0035] Please refer to Figure 1 , Figure 5 and Figure 6, the temperature reduction mechanism 6 includes a connecting sleeve 21 fixedly connected to the distribution pipe 8. One end of the connecting sleeve 21 away from the distribution pipe 8 is fixedly connected with a cooling pipe 22. A second partition plate 23 is fixedly connected to the cooling pipe 22 along the axial direction. A second rotating shaft 24 is rotatably connected through the connecting sleeve 21. One end of the second rotating shaft 24 located inside the connecting sleeve 21 is fixedly connected with a blocking block 25. One end of the second rotating shaft 24 extending into the installation frame 15 is fixedly connected with a pushing block 26. A torsion spring 27 is sleeved on the second rotating shaft 24. One end of the torsion spring 27 is fixedly connected with the connecting sleeve 21, and the other end of the torsion spring 27 is fixedly connected with the second rotating shaft 24.

[0036] In the initial state, under the action of the torsion spring 27, the blocking block 25 is in a position parallel to the axis of the connecting sleeve 21. When the temperature in one of the chambers rises to a certain height, the airbag 17 will expand, driving the sliding plate 18 to move. The movement of the sliding plate 18 drives the limiting plate 20 to move. The movement of the limiting plate 20 abuts against the pushing block 26. When the limiting plate 20 continues to move, it will cause the pushing block 26 to rotate against the force of the torsion spring 27. The rotation of the pushing block 26 drives the second rotating shaft 24 to rotate. The rotation of the second rotating shaft 24 drives the blocking block 25 to rotate. The rotation of the blocking block 25 will close half of the cavity of the cooling pipe 22, so that the low-temperature gas flowing into the cooling pipe 22 can generate a faster flow rate, increasing the heat exchange rate with the electrical components in this chamber, and further enabling the temperature of the electrical components in the relatively higher-temperature chamber to drop more quickly.

[0037] Please refer to Figure 1 and Figure 6 , the cooling pipe 22 is wrapped around the electrical components in the two chambers. The cooling pipe 22 is divided into two channels by the second partition plate 23. When the blocking block 25 closes one of the channels, the flow rate of the low-temperature gas in the other channel is accelerated, and the heat exchange rate with the electrical components is accelerated, so as to transfer the heat on the electrical components more quickly and complete the rapid heat dissipation process.

[0038] Please refer to Figure 6 , the blocking block 25 is semicircular. The blocking block 25 is used to close one of the channels of the cooling pipe 22. The semicircular blocking block 25 can only close one of the channels of the cooling pipe 22 when rotating, increasing the flow rate of the low-temperature gas flowing in the cooling pipe 22.

[0039] Please refer to Figure 5 and Figure 6 , one side of the pushing block 26 close to the sliding plate 18 is arc-shaped. The pushing block 26 abuts against the limiting plate 20. The side of the pushing block 26 in contact with the sliding plate 18 is arc-shaped, preventing the side of the pushing block 26 from abutting against the limiting plate 20 when the limiting plate 20 returns and causing the limiting plate 20 to get stuck in the sliding groove 16.

[0040] Please refer to Figure 4 , the abutting rod 19 is hinged to the pushing rod 13, and the movement of the abutting rod 19 can drive the pushing rod 13 to rotate around the first rotating shaft 9.

[0041] Please refer to Figure 2 and Figure 3 , one end of the fixed pipe 7 extending outside the box body 1 is connected to the refrigeration mechanism 5, so that the low-temperature gas generated by the refrigeration mechanism 5 is distributed through the fixed pipe 7 and flows into the cooling pipes 22 in the two chambers.

[0042] Please refer to Figure 1 , a storage cavity 28 is formed on the lower side of the box body 1, a sponge is arranged in the storage cavity 28, the storage cavity 28 is communicated with one end of the cooling pipe 22 far away from the connecting sleeve 21, the sponge can adsorb moisture, the air in the cooling pipe 22 at the end far away from the connecting sleeve 21 exchanges heat with the electrical components, and the air temperature at this place is relatively high, so that the air entering the storage cavity 28 has a relatively high temperature, enabling the sponge that adsorbs moisture to dry faster, adsorb moisture again, and maintain a dry environment inside the box body 1.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
