Description

Technical Field

[0001] This invention relates to the field of temperature control equipment technology, and more specifically, to an indoor temperature control device for a power distribution room. Background Technology

[0002] A power distribution room is a location in a power system where electrical energy is transmitted, distributed, and converted. It is primarily responsible for converting electrical energy from the power grid into voltage levels suitable for different electrical devices through transformers and other equipment, and then safely and reliably delivering it to various points of use. The power distribution room plays a crucial role in the power system, serving as a bridge connecting the power source and the electrical equipment. The electrical equipment inside the power distribution room needs to operate within a stable temperature range. High temperatures can accelerate the aging of internal components, while low temperatures can affect the start-up and operating efficiency of the equipment. The equipment in the power distribution room generates a large amount of heat during operation. If the ambient temperature is too high, it will affect the heat dissipation effect of the equipment, potentially leading to overheating and damage. Therefore, to prevent equipment failure or performance degradation due to excessively high or low temperatures, temperature and humidity monitoring systems are usually installed to monitor the indoor temperature and humidity in real time and issue timely alarms in case of abnormalities.

[0003] In related technologies, electrical equipment in power distribution rooms, such as high-voltage switchgear and low-voltage switchgear, are mostly kept in operation continuously for extended periods when no faults occur. When the load on the lines or equipment exceeds the rated value or the equipment's operational design capacity, overheating is likely to occur. Temperature monitoring systems are used to detect the indoor temperature of the power distribution room, and cooling devices are used to lower the indoor temperature and accelerate heat dissipation from the equipment. However, existing cooling methods are slow and cannot quickly reduce the operating temperature of overloaded equipment, and other equipment that is not overloaded is also susceptible to the effects of low temperatures. Summary of the Invention

[0011] Furthermore, the ventilation assembly includes multiple exhaust pipes, each with multiple air outlets. Each air outlet of the ventilation pipe corresponds to an exhaust pipe, and the multiple exhaust pipes are connected to the ventilation duct. Each exhaust pipe is equipped with a transmission assembly. A first driving member is rotatably mounted on the ventilation duct, and a reversing structure is provided on the outer wall of the ventilation duct so that the first driving member can be selectively driven to connect with a first rotating ring on one of the exhaust pipes.

[0040] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. 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.

[0041] like Figures 1 to 9 As shown, this embodiment of the invention provides an indoor temperature control device for a power distribution room. The device includes a cooling body 10, a ventilation assembly 20, a first driving component 30, and a transmission assembly 40. The cooling body 10 has a cold air outlet. The ventilation assembly 20 includes a ventilation duct 21 and an exhaust duct 22. The air inlet of the ventilation duct 21 is connected to the cold air outlet, and the air outlet of the ventilation duct 21 is connected to the air inlet of the exhaust duct 22. The air outlet of the exhaust duct 22 is oriented towards the equipment inside the power distribution room. The first driving component 30 is disposed within the ventilation duct. On the outer wall of 21, the transmission assembly 40 includes a first rotating ring 41 and a first wind-blocking mechanism 42. The first driving member 30 is driven to connect with the first rotating ring 41 so that the first rotating ring 41 is rotatably disposed at the end of the exhaust pipe 22. The inner hole of the first rotating ring 41 forms the air outlet of the exhaust pipe 22. The first rotating ring 41 is driven to cooperate with the first wind-blocking mechanism 42. The first wind-blocking mechanism 42 is movably disposed on the first rotating ring 41 and can extend into the air outlet of the exhaust pipe 22 to change the air outlet area of ​​the exhaust pipe 22.

[0042] The power distribution room indoor temperature control device provided in this embodiment includes a cooling body 10, a ventilation component 20, a first driving component 30, and a transmission component 40. The cooling body 10 has a cold air outlet, which connects to the air inlet of the ventilation duct 21, discharging the cold air into the ventilation duct 21. The air outlet of the ventilation duct 21 is connected to the air inlet of the exhaust duct 22, allowing the cold air to be discharged from the ventilation duct 21 into the exhaust duct 22. The air outlet of the exhaust duct 22 faces the equipment inside the power distribution room, facilitating the cooling of the equipment using the cold air from the cooling body 10. A first driving component 30 is provided on the outer wall of the ventilation duct 21, and the first driving component 30 is drivenly connected to a first rotating ring 41, enabling the first rotating ring 41 to be driven. The first rotating ring 41 is rotatably disposed at the end of the exhaust pipe 22. The inner hole of the first rotating ring 41 forms the air outlet of the exhaust pipe 22. The first rotating ring 41 can be driven to cooperate with the first wind-blocking mechanism 42, so that the first wind-blocking mechanism 42 is movably disposed on the first rotating ring 41 and can extend into the air outlet of the exhaust pipe 22 to change the air outlet area of ​​the exhaust pipe 22. This can increase or decrease the air outlet area of ​​the exhaust pipe 22. When rapid cooling of equipment is required, the first wind-blocking mechanism 42 can be controlled to extend into the air outlet of the exhaust pipe 22, thereby reducing the air outlet area of ​​the exhaust pipe 22 and increasing the flow rate of cold air. This can achieve rapid cooling of overloaded equipment and improve the practicality and structural reliability of the indoor temperature control device in the power distribution room.

[0043] It should be noted that the data range of the indoor temperature of the power distribution room is input into the system through the control panel or programming interface. The temperature control system detects the indoor temperature of the power distribution room in real time through temperature sensors such as thermistors and thermocouples distributed in the area, and feeds back the detected temperature data to the control center or processor of the temperature control system. The control center compares the feedback temperature data with the set target temperature to determine whether the current indoor temperature of the power distribution room is higher or lower than the target temperature. If the current temperature is higher or lower than the target temperature, it will issue a command to start the cooling unit 10 to lower or raise the area temperature.

[0044] like Figure 1 , Figure 3 , Figure 4 as well as Figure 6As shown, the first driving component 30 includes a first driving motor 31, and the transmission assembly 40 includes a second rotating ring 43. The first rotating ring 41 is rotatably disposed on the first end of the exhaust pipe 22, and the second rotating ring 43 is rotatably disposed on the second end of the exhaust pipe 22. The transmission assembly 40 also includes a second wind-blocking mechanism 44, which is movably disposed on the second rotating ring 43. A transmission structure 50 is provided between the first driving motor 31, the first rotating ring 41, and the second rotating ring 43, so that the first driving motor 31 is driven to connect with the transmission structure 50 and drive the first rotating ring 41 and the second rotating ring 43 to rotate synchronously, thereby changing the air outlet area of ​​the exhaust pipe 22. With the above structure, the first rotating ring 41 is rotatably mounted on the first end of the exhaust pipe 22, and the second rotating ring 43 is rotatably mounted on the second end of the exhaust pipe 22. The first drive motor 31 is connected to the transmission structure 50, which drives the first rotating ring 41 and the second rotating ring 43 to rotate synchronously through the transmission structure 50. The second baffle mechanism 44 is movably mounted on the second rotating ring 43, which changes the air outlet area of ​​the exhaust pipe 22 and increases the flow rate of the cold air through the first baffle mechanism 42 and the second baffle mechanism 44. This enables rapid cooling of overloaded equipment.

[0045] like Figures 4 to 9 As shown, the first wind-blocking mechanism 42 includes multiple first sector plates 421, and the second wind-blocking mechanism 44 includes multiple second sector plates 441. The multiple first sector plates 421 and multiple second sector plates 441 are arranged in a one-to-one correspondence. The transmission component 40 also includes multiple arc plates 45. The two ends of each arc plate 45 are respectively connected to the first sector plate 421 and the second sector plate 441. The space enclosed by the multiple arc plates 45 forms a flow channel 451 that connects the air inlet and air outlet of the exhaust pipe 22. With the above structure, the first sector plate 421 is movably disposed on the first end of the exhaust pipe 22, and the second sector plate 441 is movably disposed on the second end of the exhaust pipe 22. Multiple first sector plates 421 and multiple second sector plates 441 are arranged one-to-one, and multiple first sector plates 421 and multiple second sector plates 441 are connected by arc plates 45, so that the space enclosed by multiple arc plates 45 forms a flow channel 451 connecting the air inlet and air outlet of the exhaust pipe 22. When cold air is discharged into the exhaust pipe 22, the size of the space of the flow channel 451 needs to be changed, which can facilitate the change of the flow speed of cold air in the flow channel 451, thereby improving the practicality of the first wind-blocking mechanism 42 and the second wind-blocking mechanism 44.

[0046] like Figures 1 to 3As shown, the transmission structure 50 includes a rotating rod 51, a rotating gear 52, a rack 53, and a connecting plate 54. The motor shaft of the first drive motor 31 is connected to the first end of the rotating rod 51. The rotating gear 52 is sleeved on the second end of the rotating rod 51. The rack 53 is disposed on the second rotating ring 43. The rotating gear 52 and the rack 53 mesh with each other. The first end of the connecting plate 54 is connected to the first rotating ring 41, and the second end of the connecting plate 54 is connected to the second rotating ring 43. With the above structure, by connecting the first end of the rotating rod 51 to the motor shaft of the first drive motor 31, the rotating rod 51 can be driven to rotate. The rotating gear 52 is sleeved on the second end of the rotating rod 51 and meshes with the rack 53 on the second rotating ring 43. This allows the rotating gear 52 to drive the second rotating ring 43 to rotate as the rotating rod 51 rotates. The first end of the connecting plate 54 is connected to the first rotating ring 41, and the second end of the connecting plate 54 is connected to the second rotating ring 43. Thus, when the second rotating ring 43 rotates, it can drive the first rotating ring 41 to rotate simultaneously. Under the combined action of the rotation of the first rotating ring 41 and the second rotating ring 43, the first windbreak mechanism 42 and the second windbreak mechanism 44 can be movably set, thereby changing the size of the flow channel 451 and thus changing the flow speed of the cold air.

[0047] like Figures 4 to 9As shown, each first sector plate 421 is provided with a first moving rod 422. Multiple first arc-shaped grooves 423 are spaced apart along the circumferential direction of the first rotating ring 41's central axis. Each first arc-shaped groove 423 contains a first moving rod 422. The end of the first arc-shaped groove 423 abuts against the first moving rod 422, thereby driving the first moving rod 422 and the first sector plate 421 connected to it to move towards or away from the central axis of the exhaust pipe 22, thus changing the flow passage 451 of the air inlet and outlet of the exhaust pipe 22. Each of the second sector plates 441 is provided with a second moving rod 442. The second rotating ring 43 is provided with multiple second arc-shaped grooves 443 spaced apart along its central axis in the circumferential direction. Each second arc-shaped groove 443 is provided with a second moving rod 442. The end of the second arc-shaped groove 443 abuts against the second moving rod 442 to drive the second moving rod 442 and the second sector plate 441 connected to the second moving rod 442 to move toward or away from the central axis of the exhaust pipe 22, so as to change the size of the flow passage 451 of the air inlet and air outlet of the exhaust pipe 22. With the above structure, each first sector plate 421 is provided with a first moving rod 422, and the first rotating ring 41 is provided with multiple first arc-shaped grooves 423 spaced apart along its central axis in the circumferential direction. Each first arc-shaped groove 423 is provided with a first moving rod 422. The first arc-shaped grooves 423 can abut against the first moving rods 422, which facilitates the movement of the first moving rods 422 and the first sector plate 421 connected to the first moving rods 422 toward the direction of approaching or moving away from the central axis of the exhaust pipe 22. Each second sector plate 441 is provided with a second moving rod 442. Multiple second arc-shaped grooves 443 are spaced apart along the circumferential direction of the rotating ring 43. Each second arc-shaped groove 443 is provided with a second moving rod 442. The end of the second arc-shaped groove 443 abuts against the second moving rod 442 to drive the second moving rod 442 and the second sector plate 441 connected to the second moving rod 442 to move toward or away from the central axis of the exhaust pipe 22. This can drive the first sector plate 421, the second sector plate 441 and the arc plate 45 to move along the central axis of the exhaust pipe 22, thereby changing the size of the flow channel 451.

[0048] like Figures 4 to 9As shown, the exhaust pipe 22 is provided with a first fixing ring 221, and the first fixing ring 221 is provided with a plurality of first radial sliding grooves 222. A plurality of first moving rods 422 are provided in a one-to-one correspondence with the plurality of first radial sliding grooves 222. The first end of the first moving rod 422 is slidably disposed in the first radial sliding groove 222 along the extension direction of the first radial sliding groove 222. The exhaust pipe 22 is provided with a second fixing ring 223, and the second fixing ring 223 is provided with a plurality of second radial sliding grooves. A plurality of second moving rods 442 are provided in a one-to-one correspondence with the plurality of second radial sliding grooves. The second end of the second moving rod 442 is slidably disposed in the second radial sliding groove along the extension direction of the second radial sliding groove. With the above structure, the first fixing ring 221 is disposed on the first end of the exhaust pipe 22, and the second fixing ring 223 is disposed on the second end of the exhaust pipe 22. The first fixing ring 221 is provided with a first radial sliding groove 222, and the first moving rod 422 is slidably disposed in the first radial sliding groove 222. The second fixing ring 223 is provided with a second radial sliding groove, and the second moving rod 442 is slidably disposed in the second radial sliding groove. The first moving rod 422 is connected to the first sector plate 421. When the first moving rod 422 moves along the first radial sliding groove 222, it can drive the first sector plate 421 to move. When the second moving rod 442 moves along the second radial sliding groove, it can drive the second sector plate 441 to move. This makes it easy to change the size of the flow channel 451.

[0049] like Figure 1 and Figure 10As shown, the ventilation assembly 20 includes multiple exhaust pipes 22, and multiple air outlets are provided on the ventilation pipes 21. Each air outlet of the ventilation pipe 21 is correspondingly provided with an exhaust pipe 22. The multiple exhaust pipes 22 are all connected to the ventilation pipes 21. Each exhaust pipe 22 is provided with a transmission assembly 40. A first driving member 30 is rotatably provided on the ventilation pipe 21. A reversing structure 60 is provided on the outer wall of the ventilation pipe 21 so that the first driving member 30 can be selectively driven to connect with a first rotating ring 41 on one of the exhaust pipes 22. With the above structure, multiple exhaust pipes 22 are provided, and multiple air outlets are provided on the ventilation pipes 21. Each air outlet of the ventilation pipe 21 is correspondingly provided with an exhaust pipe 22, and each exhaust pipe 22 is provided with a transmission component 40. Thus, the first driving member 30 can be rotatably mounted on the ventilation pipe 21. Under the action of the reversing structure 60, the first driving member 30 can be selectively driven to connect with the first rotating ring 41 on one of the exhaust pipes 22, thereby driving the transmission component 40 on one of the exhaust pipes 22. This facilitates the selection of a suitable exhaust pipe 22 according to the location of the equipment in the power distribution room, and the first driving member 30 can be rotated and reversed to the corresponding exhaust pipe 22 by the reversing structure 60, thereby ensuring that the air outlet area on each exhaust pipe 22 can be changed.

[0050] like Figure 1 , Figure 11 as well as Figure 12As shown, the reversing structure 60 includes a mounting bracket 61, a first slide 62, a second slide 63, a second drive member 64, a reversing gear 65, and a transmission rod 66. The mounting bracket 61 is slidably mounted on the ventilation duct 21. The first slide 62 has a first arc-shaped groove 621, and the first end of the mounting bracket 61 is slidably mounted on the first arc-shaped groove 621. The second slide 63 has a second arc-shaped groove 631, and the second end of the mounting bracket 61 is slidably mounted on the second arc-shaped groove 631. The first arc-shaped groove 621 and the second arc-shaped groove 631 are concentrically arranged. A reversing rack 67 is provided on the side wall of the frame 63. A second driving member 64 is provided on the mounting frame 61. The rotation axis of the reversing gear 65 extends vertically. The second driving member 64 is driven to connect with the reversing gear 65. The reversing gear 65 meshes with the reversing rack 67 so that the mounting frame 61 slides in the first arc-shaped slide groove 621 and the second arc-shaped slide groove 631. The transmission rod 66 is rotatably provided on the mounting frame 61. The motor shaft of the first driving member 30 is driven to connect with the first end of the transmission rod 66. The second end of the transmission rod 66 is driven to engage with one of the first rotating rings 41. With the above structure, the first end of the mounting bracket 61 is slidably mounted on the first arc-shaped groove 621 of the first slide 62, and the second end of the mounting bracket 61 is slidably mounted on the second arc-shaped groove 631 of the second slide 63. A reversing rack 67 is provided on the second slide 63, and a reversing gear 65 is driven to rotate by the second driving member 64. The reversing gear 65 meshes with the reversing rack 67, which facilitates the sliding of the mounting bracket 61 within the first arc-shaped groove 621 and the second arc-shaped groove 631. Furthermore, a transmission rod 66 is provided on the mounting bracket 61, which can rotate with the mounting bracket 61. The motor shaft of the first driving member 30 is drivenly connected to the first end of the transmission rod 66, and the second end of the transmission rod 66 is drivenly engaged with one of the first rotating rings 41, making the transmission structure simple.

[0051] like Figures 11 to 15 As shown, a fitting boss 661 is provided on the second end of the transmission rod 66, and a fitting groove 411 is provided on the first rotating ring 41. The fitting boss 661 extends into the fitting groove 411 so that the transmission rod 66 and the first rotating ring 41 can be driven together. With the above structure, the fitting boss 661 is provided on the second end of the transmission rod 66, and the fitting boss 661 can extend into the fitting groove 411, so that the transmission rod 66 and the first rotating ring 41 can be driven together.

[0052] like Figure 12As shown, the rotation axis of the motor shaft of the second drive member 64 extends horizontally. The indoor temperature control device of the power distribution room also includes a first transmission gear 71, a second transmission gear 72, and a connecting shaft 73. The first transmission gear 71 is sleeved on the motor shaft of the second drive member 64. The first end of the connecting shaft 73 passes upward through the mounting bracket 61. The second transmission gear 72 is sleeved on the first end of the connecting shaft 73. The reversing gear 65 is sleeved on the second end of the connecting shaft 73 and is located below the mounting bracket 61. With the above structure, the first transmission gear 71 is sleeved on the motor shaft of the second drive member 64, the first end of the connecting shaft 73 is inserted upward through the mounting bracket 61, the second transmission gear 72 is sleeved on the first end of the connecting shaft 73, and the reversing gear 65 is sleeved on the second end of the connecting shaft 73 and located below the mounting bracket 61. The motor shaft of the second drive member 64 can drive the first transmission gear 71 to rotate. The first transmission gear 71 and the second transmission gear 72 mesh with each other, thereby driving the connecting shaft 73 to rotate. The rotation of the connecting shaft 73 can drive the reversing gear 65 to rotate and mesh with the reversing rack 67.

[0053] like Figure 1 and Figure 10 As shown, the ventilation duct 21 is equipped with multiple third driving components 74 and multiple baffles 75, which are arranged in a one-to-one correspondence. The third driving components 74 are driven to connect with the baffles 75, so that the baffles 75 can be opened and closed at the air outlet of the ventilation duct 21. With the above structure, the baffles 75 are driven to move by the third driving components 74, which allows the baffles 75 to be opened and closed at the air outlet of the ventilation duct 21, thereby enabling the multiple air outlets of the ventilation duct 21 to be opened or closed according to the heat dissipation situation.

[0054] like Figure 13 and Figure 14 As shown, a mounting groove 751 is provided on the baffle 75. When two adjacent baffles 75 are both at the air outlet position of the closed ventilation duct 21, one baffle 75 can extend into the mounting groove 751 of the other baffle 75. With the above structure, by providing a mounting groove 751 on the baffle 75, when two adjacent baffles 75 are both at the air outlet position of the closed ventilation duct 21, one baffle 75 can be embedded into the mounting groove 751 of the other baffle 75, achieving a wind-blocking effect, improving the sealing performance, and thus preventing sharp noise from being generated when airflow passes through gaps.

[0055] It should be noted that by using temperature sensors distributed in different areas of the power distribution room, the specific area where the temperature rises can be identified and the electrical equipment in the area can be locked. At this time, the control baffle 75 is activated, causing the motor shaft of the third drive unit 74 to drive the baffle 75 to rotate and cooperate with the inner wall of the ventilation duct 21 to block any two of the three air outlets. This causes the cooling body 10 to generate cold air, which passes through the unblocked air outlets on the ventilation duct 21 to the exhaust duct 22, and then reaches the area where the temperature rises. This achieves rapid cooling of the electrical equipment in the area where the temperature rises, thereby preventing equipment damage caused by prolonged overload and overheating. At the same time, other equipment that has not been overloaded will not be affected.

[0056] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0057] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0058] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0059] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0060] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.
