Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving and environmentally friendly box-type substations, and in particular to an energy-saving and environmentally friendly box-type substation. Background Art

[0002] A box-type substation, also known as a prefabricated substation or prefabricated substation, is a factory-fabricated indoor or outdoor compact distribution device that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution equipment according to a specific wiring scheme. This organically combines the functions of transformer step-down and low-voltage distribution, making it particularly suitable for urban grid construction and renovation. It is a new type of substation that has emerged after civil substations. Power transmission refers to the method of transmitting power from a power plant or power source to another. Due to the immaturity of early technology, power transmission mostly used direct current (DC) transmission, which later evolved into alternating current (AC). AC transmission has many advantages, including reduced losses and increased speed and transmission distance. Fixed box-type substations are one of the most important distribution equipment in power transmission projects.

[0003] In the prior art, a heat dissipation structure of a box-type substation and a box-type substation with publication number "CN113572064A" include a substation body, a sealed door, a transparent observation window, a heat dissipation mechanism, a recoil dust removal mechanism and a movable waterproof mechanism. The sealed door is symmetrically connected to both sides of the substation body through a hinge, and the transparent observation window is embedded in one side of the substation body. The heat dissipation mechanism is arranged on the outer wall of the substation body for dissipating heat inside the substation body. The recoil dust removal mechanism is fixed at one end of the heat dissipation mechanism for removing dust from the air inlet end of the heat dissipation mechanism to ensure that the heat dissipation mechanism always operates stably. The waterproof mechanism is rotatably connected to one side of the substation body for waterproofing the heat dissipation mechanism.

[0004] In the above technology, the heat dissipation structure cools the substation only through simple air circulation. When the external temperature is hot and close to the temperature inside the substation, this simple air circulation is difficult to cause a large change in the temperature inside and outside the substation, and thus it is difficult to cool the temperature inside the substation to a suitable temperature only through air circulation, which reduces the heat dissipation effect. Moreover, when sunlight shines on the metal substation, the interior of the substation cannot be quickly cooled down by air circulation alone, which reduces the cooling efficiency. Summary of the Invention

[0005] The present invention proposes an energy-saving and environmentally friendly box-type substation, which increases the heat dissipation effect and improves the heat dissipation efficiency, and at the same time recycles rainwater, embodying the effects of energy saving and environmental protection.

[0012] One end of each driving column away from the first gear is fixedly connected to a support plate, and one side of each support plate away from the limit cover is connected to an extraction component for extracting flowing water in the heat dissipation block to the upper side of the water flow plate.

[0013] Furthermore, the extraction assembly includes a plurality of first limiting plates, each of which is fixedly connected to the inner wall of the dust cover, each of which is rotatably connected to a screw column, and each of which is rotatably connected to a second limiting plate at one end away from the first limiting plate, and each of which is fixedly connected to the inner wall of the heat dissipation block;

[0032] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, this embodiment provides an energy-saving and environmentally friendly box-type substation, including a substation body 11, a cover 12 that seals the upper side of the substation body 11, and a plurality of sliding doors 13 for workers to enter and exit the substation body 11. The cover 12 is connected to the upper side of the substation body 11, and each sliding door 13 is slidably connected to the substation body 11.

[0034] The water flow plate 14 is fixedly connected to the upper side of the substation body 11, the dust cover 15 is fixedly connected to the upper side of the water flow plate 14, the dust cover 15 is fixedly connected to the lower side of the cover 12, the heat sink 16 is fixedly connected to the outer side of the water flow plate 14, the water collecting tray 17 is fixedly connected to the outer ring of the heat sink 16, and the two water collecting bins 18 are fixedly connected to the lower side of the water collecting tray 17, and the downward end of each water collecting bin 18 is fixedly connected to the heat sink 16 and communicates;

[0035] When the sun shines directly on the cover 12, the temperature of the surface of the cover 12 will rise sharply. After the secondary heat conduction through the dust cover 15, it will be transferred to the water flow plate 14, so that the external heat will not directly affect the surface temperature of the water flow plate 14. In addition, there is also fast-flowing air between the cover 12 and the water flow plate 14 as a conduction medium, which makes the surface temperature of the water flow plate 14 tend to be stable. As a result, the temperature of the water flowing through the surface of the water flow plate 14 will not be affected by the water flow plate 14, so that the water temperature can always be lower than the air temperature, thereby ensuring the water cooling effect.

[0036] When rainwater appears outside, some rainwater can be collected by the water collecting tray 17, and then flow into the heat sink 16 through the water collecting tank 18 for collection. Because the specific heat capacity of water is much higher than that of air, the cooling effect of the water circulation is better than the simple air cooling effect. Then, in conjunction with the air cooling, the hot air passing through the air cooling is quickly taken away by the water, which ensures that the components installed in the substation body 11 can be better cooled. In addition, the water also has the characteristic of preventing overheating, so that the heat inside the substation body 11 will not be too high, and the components are prevented from being damaged by overheating. By collecting and reusing rainwater, rainwater is also added to the heat dissipation work, which reflects the effect of energy saving and environmental protection.

[0037] The heat dissipation component 2 for improving the heat dissipation effect is connected between the water flow plate 14 and the heat dissipation block 16. The heat dissipation component 2 adopts a combination of air cooling and water cooling, so that the wind passing through the substation body 11 is further cooled. In combination with the flowing water, the cooling effect inside the substation body 11 is improved.

[0038] The driving motor 19 for driving the heat dissipation assembly 2 is fixedly connected to the upper side of the cover 12 .

[0039] like Figures 2 to 5 As shown, the heat dissipation assembly 2 includes a limit cover 21, which is fixedly connected to the water flow plate 14, two drive columns 22 are rotatably connected to the limit cover 21, one end of each drive column 22 is fixedly connected to the first gear 23, the second gear 24 is meshed between the two first gears 23, the second gear 24 is fixedly connected to the linkage column 25, the first fan 26 is connected to the lower end of the linkage column 25, the first fan 26 is fixedly connected to the lower side of the water flow plate 14, the upper end of the linkage column 25 is fixedly connected to the drive shaft of the drive motor 19, a second fan 27 is connected to the linkage column 25, and the second fan 27 is fixedly connected to the upper side of the limit cover 21, two support plates 28 are respectively fixedly connected to one end of each drive column 22 away from the first gear 23, and the side of each support plate 28 away from the limit cover 21 is connected to the extraction component that draws the flowing water in the heat dissipation block 16 to the upper side of the water flow plate 14;

[0040] When the weather is hot outside the substation body 11, the ground surface temperature will rise due to the solar radiation received by the ground and the surrounding thermal radiation. Even in the shade, the ground will still absorb some heat from the surrounding environment, so the temperature at a higher position from the ground will be lower than the temperature close to the ground. Therefore, the air around the dust cover 15 is a wind with a lower temperature than the air close to the ground, and it is far away from the ground, so that the wind will not carry too much sand and gravel. Through the extraction of the second fan 27, these relatively low-temperature gases are sucked into the cavity between the cover 12 and the water flow plate 14 through the dust cover 15, and then retained in the cavity. This part of the hot air flow will continuously exchange heat with the flowing water on the water flow plate 14. Because the specific heat capacity of water is much higher than that of air, the hot air flow will quickly exchange heat when it encounters the flowing water, that is, further reducing the temperature of this part of the air, and then part of it will quickly pass through the ventilation slot 141 and be attracted by the second fan 27, and then this part of the cooled gas will cool the various components in the substation body 11, thereby increasing the cooling effect.

[0041] like Figures 5 and 6 As shown, the extraction assembly includes a plurality of first limiting plates 31, each of which is fixedly connected to the inner wall of the dust cover 15, and an auger column 32 is rotatably connected to the first limiting plate 31. An end of each auger column 32 away from the first limiting plate 31 is rotatably connected to a second limiting plate 33, and each second limiting plate 33 is fixedly connected to the inner wall of the heat sink 16;

[0042] One end of each auger column 32 facing the first limit plate 31 is fixedly connected to the third gear 34, and the fourth gear 35 is engaged between the two third gears 34 on the same side. Each fourth gear 35 is fixedly connected to one end of the adjacent driving column 22. Through the rotation of the driving column 22, each auger column 32 is driven to rotate synchronously, so that air cooling and water cooling are carried out synchronously, thereby improving the cooling effect.

[0043] like Figures 5 and 6 As shown, the wind gathering ring 29 is fixedly connected to the water flow plate 14, and the wind gathering ring 29 is arranged between the water flow plate 14 and the limit cover 21. The wind gathering ring 29 is concentric with the first fan 26, and several ventilation slots 141 are opened on the water flow plate 14. Several filter screens 211 are fixedly connected to the limit cover 21. The first fan 26 blows the cooled cold air on the water flow plate 14 into the substation body 11 through the ventilation slots 141, and then cools the components arranged in the substation body 11. The wind gathering ring 29 guides the wind generated by the first fan 26, so that the wind passing through the wind gathering ring 29 can flow to the lower side of the water flow plate 14 more quickly, thereby further increasing the cooling effect.

[0044] like Figures 5 and 6As shown, two inclined water grooves 142 are symmetrically opened on the water flow plate 14 with the axis of the driving column 22 as the center, and the inclined water grooves 142 are inclined downward in the direction away from the limit cover 21. The water accumulation groove 161 is opened in the heat dissipation block 16, and the water accumulation groove 161 is used to collect the collected rainwater. A number of heat dissipation holes 162 are opened between the lowest point of each inclined water groove 142 and the water accumulation groove 161, and a number of water guide blocks 143 are fixedly connected to the inner wall of the inclined water groove 142, so that the water is drawn upward from the water accumulation groove 161 to the water flow plate 14 through the auger column 32, and then the water slides to both sides along the inclined water groove 142, and then the water is dispersed when passing through the water guide blocks 143, increasing the contact area between the water and the inner wall of the inclined water groove 142, so that the water can take away the heat on the water flow plate 14 as much as possible, thereby removing the heat above the water flow plate 14.

[0045] like Figures 7 and 8 As shown, a plurality of heat sinks 163 are fixedly connected to the inner wall of the water trough 161, which increases the contact area between the heat sink 16 and the flowing water, so that the flowing water can take away the heat from the heat sink 16 as much as possible, thereby improving the heat dissipation effect.

[0046] like Figures 1 to 3 As shown, the protective cover 110 is fixedly connected to the cover 12, and the drive motor 19 is arranged between the cover 12 and the protective cover 110. The protective cover 110 protects the drive motor 19 and also makes it convenient for workers to repair the drive motor 19. The drive motor 19 can be repaired by simply removing the protective cover 110 from the cover 12.

[0047] like Figure 1 As shown, the drain trough 181 is opened on the water collecting tank 18, and the excess rainwater is collected by the water collecting tray 17 and then flows into the water collecting tank 18. The excess rainwater can flow out from the drain trough 181, preventing the excess rainwater from increasing the load of the substation body 11 and ensuring that the substation body 11 can be used for a long time.

[0048] The principle of this embodiment is:

[0049] When the user needs to use it normally:

[0050] When it rains outside, rainwater flows through the cover 12 and then flows down to the water collecting plate 17, and finally flows through the water collecting tank 18 into the water sump 161 in the heat dissipation block 16 for storage. When the stored rainwater is too much, the rainwater will overflow from the drain trough 181 to the outside. At this time, the temperature outside the substation is low, which will cause the temperature difference between the inside and outside of the substation to become larger. Then, the heat dissipation effect brought by the rotation of the first fan 26 and the second fan 27 alone can offset the heat generated by the components in the substation, thereby achieving a continuous heat dissipation effect.

[0051] When the weather outside is hot, the temperature in the air is lower than that near the ground due to the radiation of heat sources. The first fan 26 and the second fan 27 are started. The second fan 27 extracts the relatively low-temperature air in the air through the dust cover 15, and accelerates this part of the airflow to reduce the temperature of the airflow. Then, several auger columns 32 rotate with the rotation of the second fan 27, and continuously extract the rainwater in the water trough 161 onto the water flow plate 14. Then, the water flows to a lower place due to gravity, and will flow through the water troughs 142 on both sides to the lowest point of the water trough 142. During the flow, part of the water will be guided by the water guide block 143, so that the water will flow into the water trough 142 as much as possible. The wall is covered, so that the flowing water can take away the heat on the water flow plate 14 during the flow, and then the flowing water will also exchange heat with the air flow drawn in by the second fan 27 during the flow. Because the specific heat capacity of water is much higher than that of air, the air flow will further reduce the temperature under the action of the water flow. At this time, some of the sand and gravel carried by the air flow will also be taken away by the water flow, and then the air flow passes through the filter 211 and moves into the limit cover 21. The first fan 26 rotates and passes through the wind gathering ring 29 to guide the air flow through the wind gathering ring 29 and then accelerate the flow rate of the air flow, further reducing the temperature of the air flow, and increasing the blowing distance of the air flow to the space inside the substation body 11, thereby improving the cooling effect and the heat dissipation effect, so that the heat inside the substation body 11 is quickly taken away.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
