Description

Technical Field

[0001] This invention relates to the field of power distribution equipment technology, and in particular to a damp and heat protection device for power distribution automation terminals. Background Technology

[0002] Distribution automation terminals mainly include feeder terminals, substation terminals, and transformer terminals. They are capable of data acquisition, control, and communication, and are crucial equipment in urban power distribution systems. Widely used in power grid construction, distribution automation terminals generate massive amounts of data. Even low-probability potential hazards can trigger power outages and cause significant losses.

[0003] In some operating environments of distribution automation terminal equipment, factors such as high temperature, high humidity, and high radiation exist, making the equipment prone to failure and affecting the normal operation of the power supply system. The internal environmental regulation requirements of distribution automation terminal equipment vary under different environmental conditions. For example, in sunny weather with ample sunlight, moisture in the air inside the equipment cannot escape compared to the outside environment, easily resulting in higher humidity inside the equipment than outside. Conversely, in rainy weather, the outside air has higher humidity but lower temperature than the air inside the equipment, making the temperature inside the equipment higher than outside.

[0004] In existing technologies, ventilation devices and filters are generally installed to regulate the internal environment of equipment. However, due to long-term use and difficulty in cleaning, the temperature and humidity regulation capabilities of filters are weakened, and the regulation effect is reduced. This makes it impossible for the internal environment of the equipment to be effectively regulated according to the external environment, increasing the risk of affecting the stable operation of the power system. Summary of the Invention

[0005] The purpose of this invention is to provide a heat and humidity protection device for power distribution automation terminals, which can adjust the temperature and humidity inside the equipment according to different external environments, while keeping the filtration mechanism dry and optimizing the temperature and humidity regulation effect.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A damp heat protection device for power distribution automation terminals, comprising:

[0008] The main body of the equipment is equipped with an air inlet and an air outlet.

[0009] A blower mechanism can be connected to the air inlet of the main body to introduce external gas into the device body;

[0010] The exhaust mechanism can be connected to the air outlet of the main body to exhaust the gas inside the device body;

[0011] The filtration mechanism can selectively dry the gas input to or output to the device body;

[0012] The filtration mechanism has two interchangeable filter sections. On sunny days, one of the two filter sections can connect the exhaust mechanism to the air outlet of the main body, and the other can connect the blower mechanism to the atmosphere. On rainy days, one of the two filter sections can connect the blower mechanism to the air inlet of the main body, and the other can connect the filtered gas and discharge it into the atmosphere.

[0013] Optionally, the filtration mechanism includes a filter slide and a filter assembly, the filter assembly being slidably connected to the filter slide so that the filter assembly can be selectively connected to the blower mechanism or the exhaust mechanism, and gas can be input into or output from the filter assembly through a plurality of through holes provided on the filter assembly.

[0014] Optionally, the filter section includes an absorbent sponge, and the filter assembly includes a filter cylinder, with the absorbent sponge disposed inside the filter cylinder to absorb moisture from the gas entering the filter cylinder.

[0015] Optionally, the filter assembly further includes a base and a support member. The base is slidably connected to the filter slide, and the support member is fixed to the base. The filter cylinder has rotating shafts at both ends along the axial direction, and the rotating shafts are connected to the support member through bearings so that the filter cylinder can rotate around the axis.

[0016] Optionally, the filter section is disposed inside the filter cylinder, and the two filter sections are separated by a partition. The partition is disposed along the axial direction of the filter cylinder. By rotating the filter cylinder, the positions of the two filter sections can be changed, so that one of the two filter sections can filter water while the other can dry itself.

[0017] Optionally, the blower mechanism is connected to the air inlet of the main body through an air inlet pipe. The air inlet pipe includes an air inlet sliding pipe and is provided with an air inlet connection position. The filter assembly or the air inlet sliding pipe can selectively cooperate with the air inlet connection position to connect the air inlet pipe.

[0018] Optionally, the exhaust mechanism is connected to the air outlet of the main body through an air outlet duct. The air outlet duct includes an air outlet sliding duct and is provided with an air outlet connection position. The filter assembly or the air outlet sliding duct can selectively cooperate with the air outlet connection position to connect to the air outlet duct.

[0019] Optionally, it also includes a circulation pipe, which includes a first circulation pipe and a second circulation pipe, wherein the first circulation pipe is used to connect the blower mechanism and the exhaust mechanism, and the second circulation pipe is used to connect the blower mechanism and the atmosphere.

[0020] Optionally, the first circulation pipe includes a circulation sliding pipe, the first circulation pipe is provided with a first connection position, and the filter assembly or the circulation sliding pipe can selectively cooperate with the first connection position.

[0021] Optionally, the first circulation pipe further includes a circulation baffle, and the first circulation pipe is also provided with a second connection position, wherein the filter assembly or the circulation baffle can selectively cooperate with the second connection position.

[0022] Optionally, the second circulation pipe is provided with a third connection position, and the filter assembly can selectively cooperate with the third connection position.

[0023] Optionally, the air inlet sliding pipe, the air outlet sliding pipe, the circulation sliding pipe, and the circulation baffle are all provided with sliding seats, which are slidably mounted on the filter slide.

[0024] Optionally, each sliding seat is provided with a spring, one end of which is fixed to the filter slide, and the other end is connected to the air inlet sliding pipe, the air outlet sliding pipe, the circulation sliding pipe, or the circulation baffle, so that the air inlet sliding pipe, the air outlet sliding pipe, the circulation sliding pipe, and the circulation baffle can be reset.

[0025] Beneficial effects:

[0026] This invention provides a heat and humidity protection device for a power distribution automation terminal. On sunny days, the ambient air is dry, and due to the high ambient temperature, the humidity inside the relatively enclosed equipment increases. A blower mechanism draws air from the outside environment into the equipment through its air inlet, replacing the high-humidity air inside. The high-humidity air is then discharged into the atmosphere through the exhaust outlet. Meanwhile, a filtration mechanism dries the air exiting the equipment. One of the two filtration sections is located between the exhaust mechanism and the exhaust outlet to reduce the humidity of the discharged air, while the other section connects the blower mechanism to the atmosphere to maintain its own humidity level. Maintaining dryness: During rainy weather, the external environment is humid but cold, while the internal temperature of the equipment is high. In this situation, the filtration mechanism dries the gas entering the equipment. One of the two filter sections connects to the blower mechanism and the air inlet of the equipment, reducing the humidity of the incoming gas and using the low-temperature gas to cool the interior of the equipment. The other filter section connects to the filtered gas and discharges it into the atmosphere to accelerate its own drying. The high-temperature gas inside the equipment is discharged through the air outlet by the exhaust mechanism. Because the two filter sections can be interchanged, when the filtration performance of one decreases, it can be replaced by the other to continue filtration, thus maintaining a high-efficiency filtration effect. This power distribution automation terminal's anti-humidity and heat device can adjust the internal temperature and humidity of the equipment according to different external environments, while keeping the filtration mechanism dry and optimizing the temperature and humidity regulation effect.

[0046] Example 1

[0047] like Figures 1-4 As shown, this embodiment provides a power distribution automation terminal damp heat protection device (hereinafter referred to as "damp heat protection device"), including a device body 1, a blower mechanism 2, an exhaust mechanism 3 and a filter mechanism 4, which is used to solve the problem of high temperature or high humidity in the internal gas of the device body 1 under different environmental conditions, and avoid affecting the normal operation of the internal structure of the device body 1.

[0048] The equipment body 1 is provided with an air inlet 11 and an air outlet 12; the blower mechanism 2 can be connected to the air inlet 11 to introduce external gas into the equipment body 1; the exhaust mechanism 3 can be connected to the air outlet 12 to exhaust the gas inside the equipment body 1; the filter mechanism 4 can selectively dry the gas entering or leaving the equipment body 1; the filter mechanism 4 is provided with two filter sections that can be interchanged. On sunny days, one of the two filter sections can be connected to the exhaust mechanism 3 and the air outlet 12, and the other can be connected to the blower mechanism 2 and the atmosphere; on rainy days, one of the two filter sections can be connected to the blower mechanism 2 and the air inlet 11, and the other can be connected to the filtered gas and discharged into the atmosphere.

[0049] The air inlet 11 and air outlet 12 of the main body can be located on the same side of the main body 1 to make reasonable use of space and avoid excessive space occupation when setting up the blower mechanism 2 and the exhaust mechanism 3. The blower mechanism 2 is provided with a blower inlet 22 to draw in air from the outside environment. The blower mechanism 2 is also provided with a first blower outlet 23, which is connected to the main body air outlet 12 to deliver air to the main body 1. The exhaust mechanism 3 is provided with a first exhaust inlet 23, which is connected to the main body air outlet 12 to deliver air from the main body 1 to the exhaust mechanism 3. The exhaust mechanism 3 is also provided with an exhaust outlet 32 ​​to discharge the air in the main body 1 into the atmosphere.

[0050] The position of the filter mechanism 4 is adjustable, making it suitable for regulating the temperature and humidity inside the equipment body 1 under different external environmental conditions. In sunny environments with high temperatures and low humidity, the external air is dry, and the high temperature can easily increase the temperature and humidity of the gas inside the relatively enclosed equipment body 1. In this case, the filter mechanism 4 is used to dry the gas output from the equipment body 1. One filter section of the filter mechanism 4 is positioned between the exhaust mechanism 3 and the air outlet 12 of the equipment body, allowing the gas to be discharged from the equipment body 1 through the air inlet 11, the filter mechanism 4, and the exhaust mechanism 3 into the atmosphere. This reduces the humidity of the discharged gas, accelerates gas discharge, and improves the efficiency of temperature and humidity regulation inside the equipment body 1. Simultaneously, the other filter section of the filter mechanism 4 is connected to the blower mechanism 2 and the atmosphere. Through the flow of dry gas, it maintains its own dryness, so that when the absorbency of the filter section used for filtering moisture decreases, the drier filter section can be repositioned to perform filtration, ensuring that the filter mechanism 4 maintains good absorbency and optimizes the filtration effect. Preferably, the filter section can directly discharge the gas input by the blower mechanism 2 to the atmosphere, or it can discharge the gas to the atmosphere after passing through the exhaust mechanism 3.

[0051] In environments with low temperatures but high humidity, such as rainy days, the temperature and humidity inside the equipment body 1 are both high. In this case, the filtration mechanism 4 is used to dry the gas entering the equipment body 1. The filtration mechanism 4 connects the blower mechanism 2 and the air inlet 11 of the equipment body. External gas flows sequentially through the blower inlet 22, the blower mechanism 2, the filtration mechanism 4, and the air inlet 11 before entering the equipment body 1. Because one of the filtration sections of the filtration mechanism 4 absorbs moisture from the gas, the humidity of the gas entering the equipment body 1 is reduced, and the low temperature of the gas can also cool the interior of the equipment body 1. Simultaneously, the other filtration section of the filtration mechanism 4 connects the filtered gas to the atmosphere, accelerating the drying process through the flow of the dried gas after moisture filtration, thus maintaining a high filtration efficiency. The high-temperature gas inside the equipment body 1 is discharged from the air outlet 12 by the exhaust mechanism 3. The simultaneous installation of the blower mechanism 2 and the exhaust mechanism 3 increases the gas flow rate, thereby promoting the replacement of gas inside the equipment body 1 and optimizing the temperature and humidity regulation effect within the equipment body 1. This heat and humidity protection device can adjust the temperature and humidity inside the equipment according to different external environments, while keeping the filter mechanism 4 dry and optimizing the temperature and humidity regulation effect inside the equipment body 1.

[0052] Optionally, such as Figures 1-9 As shown, the filter mechanism 4 includes a filter slide 41 and a filter assembly 42. The blower mechanism 2 is connected to the air inlet 11 of the main body through an air inlet pipe 21. The air inlet pipe 21 includes an air inlet sliding pipe 211. The air inlet pipe 21 is provided with an air inlet connection position. The filter assembly 42 or the air inlet sliding pipe 211 can selectively cooperate with the air inlet connection position to connect the air inlet pipe 21.

[0053] When the filter assembly 42 is connected to the exhaust mechanism 3 for drying the gas output from the main body 1, the inlet sliding pipe 211 is located at the inlet connection position, allowing the inlet pipe 21 to connect the blower mechanism 2 and the main body air inlet 11, ensuring gas input. When the filter assembly 42 is connected to the blower mechanism 2 for drying the gas input to the main body 1, the inlet sliding pipe 211 moves away from the inlet connection position (not shown in the figure). At this time, the filter assembly 42 is located at the inlet connection position to connect the blower mechanism 2 and the main body air inlet 11, allowing the gas to pass through the filtration effect of the filter mechanism 4 before entering the main body 1, reducing the gas humidity.

[0054] Optionally, the exhaust mechanism 3 is connected to the air outlet 12 of the main body through an air outlet duct 31. The air outlet duct 31 includes an air outlet sliding duct 311 and is provided with an air outlet connection position. The filter assembly 42 or the air outlet sliding duct 311 can selectively cooperate with the air outlet connection position to connect the air outlet duct 31.

[0055] When the filter assembly 42 is connected to the blower mechanism 2 to dry the gas input to the device body 1, the outlet sliding pipe 311 is located at the outlet connection position, allowing the outlet pipe 31 to connect the exhaust mechanism 3 and the main body outlet 12, ensuring gas output. When the filter assembly 42 is connected to the exhaust mechanism 3 to dry the gas output to the device body 1, the outlet sliding pipe 311 moves away from the outlet connection position (not shown in the figure). At this time, the filter assembly 42 is located at the outlet connection position to connect the exhaust mechanism 3 and the main body outlet 12, allowing gas to be output to the device body 1.

[0056] Optionally, the heat and humidity protection device further includes a circulation pipe 5, which includes a first circulation pipe 51 and a second circulation pipe 52. The first circulation pipe 51 is used to connect the blower mechanism 2 and the exhaust mechanism 3, and the second circulation pipe 52 is used to connect the blower mechanism 2 and the atmosphere.

[0057] The air inlet 11 and air outlet 12 are spaced apart on the main body 1, so that there is enough space between the air inlet pipe 21 and the air outlet pipe 31 to install the circulation pipe 5, thus optimizing space utilization.

[0058] Optionally, the first circulation pipe 51 includes a circulation sliding pipe 511, which is provided with a first connection position, and the filter assembly 42 or the circulation sliding pipe 511 can selectively cooperate with the first connection position.

[0059] Optionally, the first circulation pipe 51 further includes a circulation baffle 521, and the first circulation pipe 51 is provided with a second connection position, which the filter assembly 42 or the circulation baffle 521 can selectively cooperate with.

[0060] Optionally, the second circulation pipe 52 is provided with a third connection position, and the filter assembly 42 can selectively cooperate with the third connection position.

[0061] The blower mechanism 2 also has a second blower outlet 24. When the filter assembly 42 is connected to the blower mechanism 2 to dry the gas entering the device body 1, the circulating sliding pipe 511 moves away from the first connection position (not shown in the figure), and the filter assembly 42 is located at the first connection position. At this time, the first blower outlet 23 of the blower mechanism 2 is connected to the air inlet pipe 21 through the filter assembly 42, and the gas is delivered to the device body 1. The second blower outlet 24 is connected to the first circulating pipe 51 and then to the filter assembly 42. Since the filter assembly 42 is also engaged with the third connection position to connect to the second circulating pipe 52, the gas entering the filter assembly 42 can be delivered to the atmosphere through the second circulating pipe 52 to accelerate the gas flow in the filter assembly 42, so that the absorbent sponge 422 can dry quickly and optimize the dehumidification performance of the gas entering the device body 1. At the same time, when the filter assembly 42 is connected to the blower mechanism 2, the circulating baffle 521 engages with the second connection position.

[0062] The exhaust mechanism 3 is provided with a first exhaust inlet 33 and a second exhaust inlet 34. When the filter assembly 42 is connected to the exhaust mechanism 3 to dry the gas output from the main body 1, the circulating sliding pipe 511 can cooperate with the first connection position. At this time, the gas in the main body 1 is delivered from the exhaust pipe 31 through the filter assembly 42 to the second exhaust inlet 34; the circulating sliding pipe 511 is connected to the first circulating pipe 51, and the circulating baffle 521 moves away from the second connection position (not shown in the figure). The gas from the second blower outlet 24 of the blower mechanism 2 is delivered from the first circulating pipe 51 through the filter assembly 42 to the first exhaust inlet 33, accelerating the gas flow in the filter assembly 42.

[0063] Optionally, continue to refer to Figures 1-9 The filter mechanism 4 includes a filter slide 41 and a filter assembly 42. The filter assembly 42 is slidably connected to the filter slide 41 so that the filter assembly 42 can be selectively connected to the blower mechanism 2 or the exhaust mechanism 3. Gas can be input into or output from the filter assembly 42 through multiple through holes provided on the filter assembly 42.

[0064] Preferably, the filter assembly 42 includes a filter housing 427, which has multiple through holes. The positions of the multiple through holes can meet the connection needs under different usage conditions. Specifically, in this embodiment, the filter housing 427 has five through holes.

[0065] Optionally, the filter section includes an absorbent sponge 422, and the filter assembly 42 includes a filter cylinder 421. The absorbent sponge 422 is disposed inside the filter cylinder 421 to absorb moisture from the gas entering the filter cylinder 421.

[0066] The filter cartridge 421 is disposed inside the filter housing 427, and gas is allowed to enter or exit the filter assembly 42 through multiple through holes. The gas is dried as it flows through the absorbent sponge 422. Preferably, the filter cartridge 421 is a cylindrical structure with open ends; the filter part can be the absorbent sponge 422, or other structures capable of absorbing water.

[0067] Optionally, the filter assembly 42 further includes a base 423 and a support 424. The base 423 is slidably connected to the filter slide 41, and the support 424 is fixedly mounted on the base 423. The filter cylinder 421 has rotating shafts 426 at both ends along the axial direction. The rotating shafts 426 are connected to the support 424 through bearings so that the filter cylinder 421 can rotate around the axis. A motor 425 can be installed on the rotating shaft 426 to drive the filter cylinder 421 to rotate.

[0068] Optionally, the filter section is disposed inside the filter cylinder 421, and the two filter sections are separated by a partition 4211. The partition 4211 is disposed along the axial direction of the filter cylinder 421. By rotating the filter cylinder 421, the positions of the two filter sections can be changed so that one of the two filter sections can filter water while the other can dry itself.

[0069] After the filter mechanism 4 has been used for a period of time, the filter cylinder 421 can be rotated by the motor 425 to change the position of the two filter parts, so that the two filter parts can be alternately located in the water absorption position, so that part of the filter cylinder 421 absorbs water and the other part can be dried by high temperature or dry gas, thus ensuring the filtration capacity of the filter assembly 42.

[0070] Optionally, the air inlet sliding duct 211, the air outlet sliding duct 311, the circulation sliding duct 511 and the circulation baffle 521 are all provided with sliding seats 53, which are slidably mounted on the filter slide 41.

[0071] The filter slide 41 can be set to multiple segments, which can be connected or spaced out, etc., to meet the movement needs of the air inlet slide duct 211, air outlet slide duct 311, circulation slide duct 511, circulation baffle 521 and base 423 respectively.

[0072] Optionally, each sliding seat 53 is provided with a spring 54. One end of the spring 54 is fixed to the filter slide 41, and the other end is connected to the air inlet sliding pipe 211, the air outlet sliding pipe 311, the circulation sliding pipe 511, and the circulation baffle 521, so that the air inlet sliding pipe 211, the air outlet sliding pipe 311, the circulation sliding pipe 511, or the circulation baffle 521 can be reset.

[0073] One end of the spring 54 can be mounted on a fixed seat 55 on the filter slide 41 to fix one end of the spring 54. The other end of the spring 54 is connected to a sliding seat 53, which slides within the filter slide 41. Support structures or limiting structures can also be provided on the filter slide 41 or the sliding seat 53 for position adjustment or positioning. Resetting can also be achieved through other mechanisms, such as elastic telescopic rods. Specifically, the specific structures of the sliding seats 53 connected to the inlet sliding pipe 211, the outlet sliding pipe 311, the circulation sliding pipe 511, and the circulation baffle 521 can be different, as long as a sliding connection is achieved, allowing the pipes or baffles mounted on them to be in preset positions without interfering with each other. This heat and humidity protection device can also include a control component and a weather detection component. By monitoring weather information, the control component controls the filter mechanism 4 to be in different positions. Through a certain connection structure, the air inlet sliding pipe 211, the air outlet sliding pipe 311, the circulation sliding pipe 511 and the circulation baffle 521 can be set to be linked and moved by the filter component 42 to realize the change of different connection states.

[0074] like Figure 2 As shown, on a sunny day, the air in the external environment is dry. The filter mechanism 4 is used to dry the air output from the main body of the device 1. The filter assembly 42 is located between the exhaust mechanism 3 and the air outlet 12 of the main body. At this time, the inlet sliding pipe 211 is located at the inlet connection position to connect with the inlet pipe 21, and the circulation sliding pipe 511 is located at the first connection position; the outlet sliding pipe 311 moves away from the outlet connection position, and the circulation baffle 521 moves away from the second connection position (not shown in the figure).

[0075] Outside air enters the blower mechanism 2 through the blower inlet 22. After exiting the blower mechanism 2, one route is transported through the first blower outlet 23 and the air inlet duct 21 to the main body air inlet 11, which then enters the equipment body 1. This allows the humid air in the equipment body 1 to be transported through the main body air outlet 12 and the air outlet duct 31 to the filter assembly 42. After being filtered by one of the filter sections in the filter assembly 42, the air is transported through the air outlet duct 31 to the second exhaust inlet 34, and then enters the exhaust mechanism 3 and is discharged into the atmosphere through the exhaust outlet 32, thereby reducing the humidity inside the equipment body 1. The other route is output through the second blower outlet 24, passing through the first circulation duct 51, which includes the circulation sliding duct 511 and the filter assembly 42, and is transported to the atmosphere or the first exhaust inlet 33, so that the other filter section of the filter assembly 42 can be dried.

[0076] like Figure 3 As shown, during rainy weather, the air in the external environment is humid but the temperature is low. The filter mechanism 4 is used to dry the air input to the main body 1. The filter assembly 42 is located between the blower mechanism 2 and the main body air inlet 11. At this time, the outlet sliding pipe 311 is located at the outlet connection position to connect the outlet pipe 31, and the circulation baffle 521 is located at the second connection position; the inlet sliding pipe 211 moves away from the inlet connection position, and the circulation sliding pipe 511 moves away from the first connection position (not shown in the figure).

[0077] Outside gas enters the blower mechanism 2 through the blower inlet 22 and exits from the blower mechanism 2. It is then transported to the equipment body 1 through the first blower outlet 23, the air inlet pipe 21, and a filter section of the filter assembly 42 connected to it. Due to the filtration effect of the filter section, the gas entering the equipment body 1 is a relatively dry and low-temperature gas. The original high-temperature gas in the equipment body 1 can be output through the air outlet 12 to reduce the temperature inside the equipment body 1. The gas in the equipment body 1 is transported to the second exhaust inlet 34 through the air outlet 12 and the exhaust pipe 31 connected to the exhaust sliding pipe 311, and then discharged through the exhaust outlet 32 ​​via the exhaust mechanism 3. Another path involves the humid gas flowing through one of the filter sections in the filter assembly 42, then flowing through the second circulation pipe 52 to another filter section before being discharged into the atmosphere. The dry gas that has already filtered out the moisture dries the other filter section, ensuring that at least one filter section in the filter assembly 42 is always dry. When the water absorption performance of the filter section used for filtering moisture decreases, the other filter section can be replaced to ensure the filtration effect.

[0078] Example 2

[0079] This embodiment provides a power distribution automation terminal damp heat protection device, which is basically the same as the power distribution automation terminal damp heat protection device in Embodiment 1, except that the overall arrangement is different.

[0080] The heat and humidity protection device can be installed inside the main body 1. To reduce space occupation, the circulation pipe 5 can be arranged vertically with the air inlet pipe 21 and the air outlet pipe 31. Since the air inlet sliding pipe 211 and the circulation sliding pipe 511 have similar movement directions and timing, they can be arranged vertically and connected in parallel with the filter assembly 42 so that they can be moved by the filter assembly 42 and avoid interference problems.

[0081] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
