Description

Technical Field

[0001] This utility model relates to the field of wind and sand protection structure technology, specifically a wind and sand protection structure for charging piles in plateau areas. Background Technology

[0002] High-altitude regions have harsh climates with strong winds and frequent sandstorms. Sand and dust can easily penetrate outdoor equipment, causing malfunctions or shortening its lifespan. Charging stations, as essential components for electric vehicles, are typically equipped with ventilation and heat dissipation structures to ensure their normal operation. However, traditional ventilation designs often lack effective measures to prevent sand and dust from entering the equipment through the air inlets, accumulating on critical components such as circuits and radiators. This severely affects heat dissipation efficiency and can even lead to safety hazards such as short circuits and overheating.

[0003] Currently, most common sand-proof structures on the market use a single filter or simple louvers, which have limited interception efficiency in strong wind and sand environments, are prone to clogging, and are inconvenient to clean and maintain. Especially in high-altitude, windy and sandy environments, existing structures are unable to effectively filter fine particles and cannot adapt to changes in airflow speed during strong winds. There is an urgent need for a sand-proof structure that can intercept multiple layers, is easy to clean, and does not affect heat dissipation requirements.

[0004] Therefore, a wind and sand-proof structure for charging piles in plateau areas is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wind and sand resistant structure for charging piles in plateau areas, with the aim of solving the aforementioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A wind and sand protection structure for charging piles in high-altitude areas includes:

[0008] Several air boxes are provided, and the interior of each air box is equipped with several baffles that can guide the airflow. One side of each air box is an air outlet, and the other side is fixed with a convection frame. The convection frame has a two-layer sand-proof component for secondary blocking of wind and sand. A collection box is slidably installed at the bottom of each air box.

[0009] Preferably, the baffles are staggered and inclined inside the air box, and the airflow is guided in a wave-like manner.

[0010] Preferably, the interior of the air box is provided with a dust inlet at each of the lower baffles. The dust inlet is located on the side of the baffle away from the air outlet of the air box. When the collection box and the air box are connected, the air box is connected to the collection box through the dust inlet.

[0011] Preferably, the collection box is fixed with support plates at both ends, and the bottom of the air box is fixed with a support frame with a first groove at each end of the support plate. The support plate is slidably connected to the support frame through the first groove and is supported by the first groove.

[0012] Preferably, the sand-proof component further includes a first sand-proof plate and a second sand-proof plate snapped into place inside the convection frame. The first sand-proof plate is located on the side closer to the air box, and the second sand-proof plate is located on the side farther from the air box. Both the first and second sand-proof plates have built-in filters, and the mesh size of the filter corresponding to the first sand-proof plate is larger than that of the filter corresponding to the second sand-proof plate.

[0013] Preferably, the outer edge of the second sandproof plate near the first sandproof plate is fixed with an outer frame. When the sandproof component is fully installed inside the convection frame, the second sandproof plate presses against the first sandproof plate through the outer frame, and a gap is left between the first sandproof plate and the second sandproof plate.

[0014] Preferably, the barrier plate is snapped onto the inner wall of the air box by inserts, and a baffle is detachably installed on one side of the air box.

[0015] Preferably, the side of the support plate away from the collection box is provided with several automatically pop-out protrusions, and the inner wall of the support plate is provided with a second sliding groove corresponding to each protrusion. The protrusion is slidably connected to the second sliding groove by a limiting piece, and a reset spring is built into the second sliding groove, which presses the limiting piece against the groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This utility model provides a wind and sand protection structure for charging piles in plateau areas. By setting up multiple layers of staggered and inclined baffles, a wave-shaped airflow channel is formed, which effectively slows down the airflow speed, enhances the settling and interception effect of sand and dust particles, and reduces the probability of sand and dust entering the charging pile.

[0018] The design features a double-layer sand-proof board. The first sand-proof board intercepts larger particles, while the second sand-proof board filters fine particles, achieving secondary barrier and further enhancing the wind and sand protection performance.

[0019] The bottom is equipped with a sliding and detachable collection box, which makes it easy to clean up the deposited sand and dust, reducing the frequency and difficulty of maintenance;

[0020] Both the barrier panels and sand-proof panels are installed using a snap-fit ​​method, with a modular structure that facilitates replacement and cleaning, extending their service life. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 and Figure 2 The embodiments proposed in this application include: a windproof and sandproof structure for charging piles in plateau areas, comprising several air boxes 10, with several baffles 30 inside the air boxes 10 to regulate the airflow inside the air boxes 10. One side of the air box 10 is an air outlet, through which airflow enters or exits. A convection frame 20 is fixed on the other side of the air box 10. The windproof and sandproof structure is connected to the air inlet and outlet of the charging pile through the convection frame 20. An installation frame 21 is fixedly provided at the outer end of the convection frame 20. The installation frame 21 can be installed and fixed to the outer wall of the charging pile by fasteners such as bolts. During installation, a sealing gasket can be provided between the convection frame 20 and the charging pile to enhance the sealing between the convection frame 20 and the charging pile and prevent sand particles from entering through the gap between the convection frame 20 and the charging pile. The convection frame 20 has a two-layer sandproof component 50 built in, which provides secondary protection against wind and sand. A collection box 40 is slidably provided at the bottom of the air box 10 to collect sand particles.

[0030] Specifically, such as Figure 2 and Figure 3 The baffles 30 are staggered inside the air box 10, and each baffle 30 is inclined, so that the airflow will come into contact with the baffles 30 as it enters and exits inside the air box 10. During this process, the baffle plate 30 blocks the dust and dirt carried in the airflow, causing the dust particles to fall downwards and making it difficult for them to follow the airflow through the baffle plate 30 into the interior of the charging pile, thus playing a role in preventing wind and sand. The setting of multiple baffle plates 30 can block the dust particles in the airflow multiple times, further improving the wind and sand prevention effect. As the airflow enters and exits within the air box 10, the multiple blocking of the wind and sand in the airflow by several baffle plates 30 makes the airflow wave-shaped during its entry and exit within the air box 10, thereby slowing down the airflow speed within the air box 10. At the same time, because this wind and sand prevention structure is connected to the air inlet and outlet of the charging pile through the connection of one end of the convection frame 20, the setting of several baffle plates 30 and the wave-shaped airflow can slow down the airflow speed when entering the air box 10 in windy and strong wind weather, thereby slowing down the airflow speed from the air inlet into the charging pile in windy and strong wind weather, further reducing the wind and sand intrusion at the air inlet of the charging pile.

[0031] like Figure 3 and Figure 4 Inside the air box 10, a dust inlet 11 is provided at each of the lower baffle plates 30. The dust inlet 11 is located on the side of the baffle plate 30 away from the air outlet of the air box 10. When the collection box 40 is connected to the air box 10, the air box 10 is connected to the collection box 40 through the dust inlet 11, so that the sand and dust particles blocked by the baffle plates 30 fall into the collection box 40 and are collected by the collection box 40. The two ends of the collection box 40 are respectively A support plate 41 is fixedly installed. At the bottom of the air box 10, a support frame 13 with a first sliding groove is fixedly installed at both ends of the support plate 41. The support plate 41 can be slidably connected to the support frame 13 through the first sliding groove, and the support plate 41 is supported through the first sliding groove, thereby supporting the collection box 40 located at the bottom of the air box 10, so that the collection box 40 can slide at the bottom of the air box 10, which facilitates the disassembly and assembly of the collection box 40 and the air box 10, and cleans the sand and dust particles collected in the collection box 40.

[0032] like Figure 4 and Figure 6The sand-proof component 50 includes a first sand-proof plate 51 and a second sand-proof plate 52 snapped into the convection frame 20. The sand-proof component 50 primarily provides further dust protection for the airflow entering the barrier plate 30 and the charging pile. The first sand-proof plate 51 is located closer to the air box 10, and the second sand-proof plate 52 is located further away from the air box 10. Both the first sand-proof plate 51 and the second sand-proof plate 52 have built-in filters. The mesh size of the filter on the first sand-proof plate 51 is larger than that on the second sand-proof plate 52, allowing airflow to pass through the convection frame 20 and enter the charging pile after entering the air box 10. During the process, the first sand-proof plate 51 blocks relatively large particles in the airflow, and the second sand-proof plate 52 blocks relatively small particles in the airflow. The outer edge of the side of the second sand-proof plate 52 closest to the first sand-proof plate 51 is fixed with an outer frame 521. When the sand-proof component 50 is fully installed inside the convection frame 20, the second sand-proof plate 52 presses against the first sand-proof plate 51 through the outer frame 521, so that the sand-proof component 50 can be snapped and firmly attached inside the convection frame 20, while a partial gap can be left between the first sand-proof plate 51 and the second sand-proof plate 52. Similarly, in this state, the other side of the second sand-proof plate 52 is pressed against the outer wall of the charging pile.

[0033] Furthermore, the baffle plate 30 is snapped onto the inner wall of the air box 10 via the insert 31. This snap-fit ​​method allows the baffle plate 30 to be easily removed from the air box 10 in case the insert 31 is damaged or aged. A baffle plate 12 is installed on one side of the air box 10. The baffle plate 12 is fixed to the air box 10 with fasteners such as bolts, which facilitates the removal and installation of the baffle plate 12 from the air box 10. When the baffle plate 12 is connected to the air box 10, a sealing gasket can be placed between the baffle plate 12 and the air box 10 to improve the sealing effect between the baffle plate 12 and the air box 10 and prevent sand and dust particles from entering the air box 10 through the gap between the baffle plate 12 and the air box 10.

[0034] Further, such as Figure 3 , Figure 4 and Figure 5A number of protrusions 60 are slidably connected to the side of the support plate 41 away from the collection box 40. A second sliding groove is provided on the inner wall of the support plate 41 corresponding to each protrusion 60. The protrusion 60 is slidably connected to the second sliding groove by a limiting piece 61. A return spring 62 is built into the second sliding groove. The return spring 62 presses against the limiting piece 61, so that the protrusion 60 can automatically slide outward from the support plate 41 without external force. At the same time, a slot corresponding to the protrusion 60 is provided on the inner side of the support frame 13 near the corresponding support plate 41. When the collection box 40 and the air box 10 are in a fully connected state, the protrusion 60 automatically pops outward from the support plate 41 and engages with the corresponding slot, so that the collection box 40 is difficult to slide out from the bottom of the air box 10 without human intervention.

[0035] Working principle: This windproof and sandproof structure is mainly used for outdoor charging poles in high-altitude areas. After the convection frame 20 of the windproof and sandproof component is connected to the wind outlet of the charging pile, the mounting frame 21 can be installed and fixed to the charging pile by fasteners such as bolts, thus completing the installation between the windproof and sandproof structure and the charging pile.

[0036] When sandstorms occur, the airflow carrying sand and dust enters the air box 10. After entering the air box 10, the airflow is guided by several staggered baffles 30, which reduce the flow velocity and intercept most of the sand and dust particles in the airflow. The intercepted sand and dust particles fall into the collection box 40. After the airflow passes through the air box 10 and enters the convection frame 20, the sand and dust are intercepted a second time by the sand-proof component 50. In this process, the first sand-proof plate 51 intercepts the relatively large sand and dust particles remaining in the airflow, and the second sand-proof plate 52 intercepts the very few and trace small sand and dust particles remaining. Finally, the airflow that has undergone multiple dust removals enters the air outlet of the charging pile.

[0037] The sand-proof structure collects sand particles through the collection box 40. The collection box 40 needs to be slid out from the bottom of the wind box 10 periodically to empty and clean the sand collected inside. At the same time, there is also a possibility that a small amount of sand may remain in the space between the first sand-proof plate 51 and the second sand-proof plate 52. Similarly, the convection frame 20 should be removed from the charging pile periodically to clean the sand and dust remaining between the first sand-proof plate 51 and the second sand-proof plate 52. Since the amount of sand and dust accumulated between the first sand-proof plate 51 and the second sand-proof plate 52 is relatively smaller than that collected in the collection box 40 in the same unit of time, the cleaning frequency between the first sand-proof plate 51 and the second sand-proof plate 52 can be less than the cleaning frequency of the collection box 40. In addition, the cleaning frequency of the two should be increased during periods of more frequent windy and sandy weather.

[0038] The windproof and sandproof structure uses several baffles 30 to block sand and dust in the airflow. However, the multiple baffles 30 may reduce the airflow at the charging pile's air inlet, thus affecting the heat dissipation of the charging pile itself. Therefore, several windproof and sandproof structures are installed between the charging pile and the charging pile. Multiple air inlets can be opened on the outer wall of the charging pile to increase the overall airflow and maintain the original heat dissipation effect of the charging pile.
