Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ventilation devices, in particular to a waterproof ventilation structure and a waterproof ventilation device. Background Art
[0002] Typically, a heat source is located within a non-enclosed housing with air inlet and outlet channels. Hot air tends to flow upward, so an air inlet is provided at the bottom of the housing and an air outlet at the top. This allows the use of air density and thermal pressure differences to expel hot air from the top outlet and draw in cool air from the bottom inlet, thereby lowering the temperature of the heat source within the housing. For ease of operation, non-enclosed housings are often installed outdoors. When the outdoor environment in which the housing is used is subject to harsh conditions such as typhoons and heavy rain, it is unavoidable for rain or other moisture to seep into the housing. Furthermore, because the external housings of existing heat sources are generally enclosed or semi-enclosed, their heat dissipation efficiency is poor, which can easily lead to excessive temperatures within the housing, potentially compromising the safety of the heat source.

[0035] In recent years, heavy rains have led to increasingly frequent urban flooding. In areas severely affected by flooding, dry-type transformers are often used in household power distribution rooms, often located in basements. These basement distribution transformers are often damaged by flooding, leading to power outages and difficulty in rapid replacement, resulting in significant economic losses. Furthermore, restoring power requires significant manpower and resources, severely impacting people's daily lives and production.
[0036] In view of this, the present invention provides a waterproof ventilation structure and a waterproof ventilation device. The waterproof ventilation structure includes a ventilation duct, a top cover, a rain shield, and a connecting structure. The top cover covers the top of the ventilation duct, the rain shield is located outside the ventilation duct and connected to the outer periphery of the top cover, and a cavity is formed between the rain shield and the ventilation duct. The cavity is used to allow liquid that leaks along the top cover to flow out of the waterproof ventilation structure. The bottom of the ventilation duct is provided with a connecting piece for connecting to a housing with air inlet and outlet channels. By combining the top cover and the rain shield, the present invention can effectively improve the wind and rainproof capabilities of the ventilation structure. Furthermore, the waterproof ventilation structure can be installed in a non-enclosed housing with an air inlet to accelerate the gas flow rate within the housing, thereby improving the heat dissipation efficiency within the housing.
[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0038] See also Figure 1This is a cross-sectional view of the waterproof ventilation structure provided by the embodiment of the utility model. Figure 1 As shown, the waterproof ventilation structure includes a ventilation duct 110, a top cover 120, and a rain cover 130, wherein the top cover 120 covers the top of the ventilation duct 110, the rain cover 130 is arranged on the outside of the ventilation duct 110 and is connected to the outer periphery of the top cover 120, and a cavity 140 is formed between the rain cover 130 and the ventilation duct 110.
[0039] In some embodiments, as Figure 2 and Figure 6 As shown, the top cover 120 is provided with studs 230, and the upper end of the rain cover 130 is provided with a reinforcement plate and mounting holes. The rain cover 130 can be installed through the mounting holes and studs 230, thereby assembling with the top cover 120. In the waterproof ventilation structure's wind and rain protection, the top cover 120 provides the primary wind and rain protection, while the rain cover 130 provides the secondary wind and rain protection. It is understood that wind and rain intrusion may cause water accumulation within the ventilation duct 110, increasing humidity within the duct, leading to corrosion and decay, thereby shortening the service life of the ventilation duct 110. Strong winds and heavy rain may also introduce a large amount of debris and contaminants into the ventilation duct 110, affecting the normal operation of the ventilation system and even clogging the ventilation duct 110, resulting in reduced or ineffective ventilation. By placing the top cover 120 on top of the ventilation duct 110, external wind, rain, debris, and contaminants can be effectively prevented from entering the ventilation duct 110, preventing clogging and water accumulation, thereby ensuring the ventilation efficiency and service life of the ventilation duct 110.
[0040] In some embodiments, when liquid flows into the waterproof ventilation structure, it can be discharged from the top cover 120, then enter the cavity 140, and flow out of the outside through the cavity 140. The top cover 120 can be composed of a horizontal surface and four trapezoidal dam bodies, such as Figure 1 As shown, the cross-section of top cover 120 is trapezoidal. This design effectively improves drainage efficiency. As can be understood, as water flows along an inclined surface, it is accelerated by gravity, thereby speeding up the drainage process. Furthermore, the trapezoidal structure reduces the likelihood of water stagnation during drainage, thus preventing water pollution and environmental issues caused by accumulated water. Furthermore, compared to conventional planar structures, the trapezoidal structure can reduce pipe size while maintaining the same drainage capacity, saving materials and costs.
[0041] In some embodiments, as Figure 6 As shown, a connection structure 610 can be provided at the bottom of the ventilation duct 110, and the connection structure 610 can be connected to a shell having an air inlet and outlet channel, utilizing the density difference and thermal pressure difference of the air to accelerate the gas flow speed in the shell.
[0042] In some embodiments, it is understood that when a heat source is within a non-enclosed housing having an air inlet and outlet, hot air will flow upward. Generally, an air inlet is provided at the bottom of the non-enclosed housing and an air outlet is provided at the top. This allows the use of air density differences and thermal pressure differences to expel hot air from the top outlet and draw in cool air from the bottom inlet, thereby reducing the temperature of the heat source within the housing. By arranging the waterproof ventilation structure above the non-enclosed housing having an air inlet, the upward flow of hot air can be utilized to accelerate the flow of gas within the housing by utilizing the air density differences and thermal pressure differences.
[0043] In some embodiments, the waterproof ventilation structure can also help optimize the heat dissipation of the transformer and maintain its normal operating temperature. Typically, transformers are designed with vents and ventilation slots located at the bottom and top of the transformer, allowing ambient air to naturally circulate inside the transformer and remove heat. Installing the waterproof ventilation structure at the transformer's vents can accelerate the flow of air within the transformer, effectively dissipating heat and maintaining an appropriate operating temperature. This, in turn, extends the life of the equipment and ensures its reliability and safety.
[0044] In some embodiments, as Figure 2 As shown, the ventilation duct 110 includes multiple sub-ducts 210, and the multiple sub-ducts 210 can be stacked to form the ventilation duct 110. Since the ventilation duct 110 is a multi-section stacked structure, during actual use, the ventilation duct 110 can be stacked to the required height according to actual needs.
[0045] In some embodiments, as Figure 2 As shown, a flange structure 220 can be provided on the outer periphery of the pipe mouth of the sub-pipe 210. Since each section of the sub-pipe 210 is provided with a waterproof flange structure 220, after the pipes are stacked, it can effectively prevent outdoor wind and rain from splashing into the interior of the ventilation duct 110.
[0046] In some embodiments, the upper end of the ventilation duct 110 is provided with a ventilation port 150, specifically, as shown in FIG. Figure 1 As shown, a vent 150 is provided at the upper end of the topmost pipe of the ventilation duct 110, and hot air can be emitted into the external environment through the vent 150.
[0047] In some embodiments, vents 150 can be set around the upper end of the topmost pipe of the ventilation duct 110. By setting vents 150 on all four sides of the upper end of the pipe, fresh air can be effectively introduced and heat can be discharged, avoiding the formation of dead corners between the vents, hindering air flow, and ensuring the overall ventilation effect.
[0048] In some embodiments, as Figure 1 and Figure 3 As shown, a mesh structure 310 is provided below the periphery of the top cover 120. By providing the mesh structure 310, while ensuring ventilation and heat dissipation, it can also prevent dust layers, small animals and other debris or pollutants from the external environment from entering the waterproof ventilation structure.
[0049] In some embodiments, as Figure 4 As shown, a fixing element 410 can be provided on the topmost section of the ventilation duct 110, and the ventilation duct 110 and the mesh structure 310 can be assembled through the fixing element 410. For example, a flange can be provided on the topmost section of the ventilation duct 110, and the ventilation duct 110 can be assembled with the mesh structure 310 through the flange.
[0050] In some embodiments, as Figure 1 and Figure 5 As shown, a waterproof baffle 160 is provided circumferentially on the outer wall of the ventilation duct 110. The waterproof baffle 160 is prism-shaped, with a larger upper part and a smaller lower part, which can effectively prevent outdoor wind and rain from splashing onto the mesh structure (i.e., the hot air exhaust outlet).
[0051] In some embodiments, as Figure 5 As shown, the lower end of the waterproof baffle 160 is also provided with a drain outlet 510. When rainwater flows downward from the top of the ventilation structure into the waterproof baffle 160, the drain outlet 510 can discharge the rainwater from the bottom in time, so that the rainwater will not accumulate, thereby extending the service life of the structure.
[0052] In some embodiments, the waterproof ventilation structure is further provided with a first connecting plate 170, such as Figure 1 As shown, a first connecting plate 170 is provided on the outer periphery of the topmost pipe of the ventilation duct 110 , and the first connecting plate 170 can be connected and fixed to the waterproof baffle 160 .
[0053] See also Figure 5 ,exist Figure 5 In the embodiment, the first connecting plate 170 includes a plurality of connecting pieces, which are distributed around the duct. One end of each connecting piece is connected to the upper portion of the waterproof baffle 160, and the other end is connected to the outer wall of the ventilation duct 110, which helps to improve the overall strength of the waterproof ventilation structure.
[0054] In some embodiments, the waterproof ventilation structure is further provided with a second connecting plate 180, such as Figure 1 As shown, a second connecting plate 180 is provided on the outer periphery of the bottom of the ventilation duct 110. The second connecting plate 180 can be connected and fixed to the rain cover 130, thereby improving the overall strength of the waterproof ventilation structure.
[0055] See also Figure 5-6 ,exist Figure 5-6In the embodiment, the second connecting plate 180 includes a plurality of connecting pieces, which are distributed around the pipe and connected to the lower end of the rain cover 130, which is beneficial to improving the overall strength of the waterproof ventilation structure.
[0056] In addition, the utility model also provides a waterproof ventilation device, such as Figure 7 As shown, the waterproof ventilation device includes a waterproof ventilation structure 710 and a shell 720. It should be noted that the shell 720 is provided with air inlet and outlet channels. By installing the waterproof ventilation structure 710 at the upper end of the air inlet and outlet channels of the shell 720, the gas flow rate in the shell can be increased. When there are electrical components inside the shell 720 and the electrical components generate a large amount of heat during operation, the waterproof ventilation structure 710 can be provided to enable the components inside the shell 720 to effectively dissipate heat during operation and maintain an appropriate operating temperature, thereby extending the service life of the equipment and ensuring the reliability and safety of the equipment.
[0057] The preferred embodiments of the present invention are described above with reference to the accompanying drawings, but are not intended to limit the scope of the present invention. Any modifications, equivalent substitutions, and improvements made by those skilled in the art without departing from the scope and essence of the present invention should be within the scope of the present invention.
