Description

Technical Field

[0001] The present invention relates to the technical field of power equipment, and in particular to a waterproof temperature-controlled power cabinet. Background Art

[0002] Distribution cabinets, as a common form of power infrastructure, integrate numerous electrical components, generating significant heat during operation. Existing technologies often dissipate heat by providing heat dissipation holes in the cabinet. However, when distribution cabinets are used outdoors, rainwater can easily seep in through the holes, potentially damaging electrical components and even causing short circuits or electrical leakage.

[0003] Regarding the power distribution cabinet with active heat dissipation function disclosed in the patent publication number "CN116845718B", a heat dissipation slot is controlled by setting a shield controlled by water level buoyancy. On rainy days, the shield will block the heat dissipation slot, although it can prevent rainwater from entering the equipment through the heat dissipation slot.

[0004] However, in actual use, when it rains, rainwater will not only penetrate through the heat dissipation holes, but also easily penetrate into the interior along the gaps on the outside of the cabinet, causing short circuits in electrical components and seriously affecting the safe operation of the equipment. Moreover, the device will not work until the rainwater accumulates to a certain amount, and there is obvious lag, which makes it impossible to block the rainwater intrusion path in time.

[0005] Based on this, the present application proposes a waterproof temperature-controlled power cabinet. Summary of the Invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a waterproof temperature-controlled power cabinet.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: A waterproof temperature-controlled power cabinet, comprising a cabinet body, a cabinet door, an air duct, two supports, two heat dissipation components, two air drying components, a rain shield and ventilation component, a flow guide component, and a transmission component. The cabinet body is used to accommodate various electrical components. The cabinet door is rotated to close or open the cabinet body. The air duct is provided above the cabinet body for ventilation and heat dissipation. The two supports support and install the rain shield and ventilation component. The two heat dissipation components are symmetrically arranged on both sides of the cabinet, and generate negative pressure through high-speed rotation to guide the hot air flow in the cabinet to be discharged. The two air drying components respectively receive signals and generate rotation movements, thereby guiding the hot air discharged by the heat dissipation components to dry the outside of the cabinet through a fixed path; The rainproof and ventilation components produce a sliding action by rotation to complete storage or expansion, so that the cabinet can be ventilated or a rainproof barrier is formed above both sides of the cabinet. The guide component accelerates the circulation of hot air in the cabinet by swinging back and forth in the cabinet, and ensures that rainwater cannot enter the interior of the cabinet through the air guide port by unified rotation and closure. The transmission component realizes synchronous operation by connecting the air-drying component, the windproof and ventilation component and the guide component.

[0008] Preferably, the two air-drying components are respectively arranged on both sides of the cabinet, and the air-drying components are composed of a guide part and a push part; The guide part changes the direction of hot air flow by rotating, so that the hot air is dried outside the cabinet through a preset path under the negative pressure generated by the heat dissipation component; The pushing part sends and receives signals when it rains, and pushes to generate a sliding rotation action, thereby causing the guide part to rotate.

[0009] Preferably, the rainproof and ventilation assembly is fixedly installed above the cabinet, and the rainproof and ventilation assembly consists of a storage portion and a rotating and sliding portion; The storage portion is stored by sliding horizontally inward, forming a ventilation space above the cabinet body to facilitate heat dissipation from the cabinet body. The storage portion is expanded by sliding horizontally to both sides, forming a rain shield above both sides of the cabinet body, thereby shielding both sides of the cabinet body from rain. The rotating sliding portion generates a sliding motion when rotating, thereby causing the storage portion to be stored or expanded.

[0010] Preferably, the air guide assembly is provided on the cabinet body, and is composed of a swinging portion and a reciprocating sliding portion. The swinging portion generates continuous swinging by reciprocating rotation at the air guide port, thereby accelerating the external airflow and the internal airflow to circulate through the air guide port. When the swinging portion is stationary, it can rotate and reset under the action of elasticity to close. The reciprocating sliding part rotates and then slides back and forth, thereby driving the swinging part to rotate back and forth at the air guide port, and a mounting part is provided on the outer side of the reciprocating swinging part.

[0011] Preferably, the reciprocating swinging part is fixedly mounted on the mounting part, and the mounting part slides downward after rotating, thereby releasing the control of the reciprocating sliding part on the swinging part and making the swinging part stationary.

[0012] Preferably, the transmission assembly includes a rotating part and a transmission part. The rotating part can start to rotate when driven by the pushing part, and the rotating part can drive the rotating sliding part and the mounting part to start working through rotation; the transmission part drives the rotating part through the pushing part, and in turn makes the rotating sliding part and the mounting part start working.

[0013] The present invention has the following beneficial effects: The air drying component, under the negative pressure of the heat dissipation component, directs airflow along a pre-set path through the cabinet exterior. When it rains, the pusher receives a signal to activate the guide, allowing airflow to quickly remove moisture from the cabinet surface. This continuous air circulation accelerates evaporation of moisture from the cabinet exterior, preventing moisture from accumulating and seeping into the cabinet interior or adhering to electrical components, potentially causing short circuit damage.

[0014] When the rain shield and ventilation assembly's storage section slides inward, a ventilation channel is formed above the cabinet, promoting the natural exhaust of heat from the cabinet. When it slides outward, a rain shield is formed above the cabinet on both sides, preventing rain from splashing onto the outside. The rotating sliding section automatically switches between ventilation and rain shielding by rotating and sliding, maintaining heat dissipation and ventilation in calm weather while quickly protecting the cabinet's sides during rainfall, preventing rain from entering through gaps in the cabinet's sides.

[0015] The swinging portion of the air guide assembly reciprocates at the air vents, accelerating air exchange between the cabinet interior and exterior through the vents. When stationary, the vents are closed by elastic return, preventing rainwater from entering the cabinet through the vents. Furthermore, the swinging portion enhances the efficiency of heat removal from the cabinet during periods of low rainfall. By controlling the opening and closing of the vents and guiding airflow, the cabinet's heat dissipation requirements and the roof's waterproof performance are balanced, ensuring a safe operating environment for the electrical components within the cabinet.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1:

[0019] Reference Figures 1-3 and Figure 12 A waterproof temperature-controlled power cabinet includes a cabinet body 1, a cabinet door 8, an air duct 26, two supports 20, two heat dissipation components, two air drying components, a rain shield and ventilation component, a guide component and a transmission component. The cabinet body 1 is used to accommodate various electrical components. The cabinet door 8 closes or opens the cabinet body 1 by rotation. The air duct 26 is provided above the cabinet body 1 for ventilation and heat dissipation. The two supports 20 support and install the rain shield and ventilation components.

[0020] The two heat dissipation components are symmetrically arranged on both sides of the cabinet 1. They generate negative pressure through high-speed rotation, guiding the hot air flow inside the cabinet 1 to be discharged. The two air drying components receive signals and generate rotation movements, thereby guiding the hot air discharged from the heat dissipation components to dry the outside of the cabinet 1 through a fixed path; The rainproof and ventilation components produce a sliding motion through rotation to complete storage or expansion, so that the cabinet 1 is ventilated or both sides of the cabinet 1 are shielded from rain. The guide component accelerates the circulation of hot air in the cabinet 1 by swinging back and forth in the cabinet 1, and ensures that rainwater cannot enter the interior of the cabinet 1 through the air guide port 26 by unified rotation and closure. The transmission component realizes synchronous operation by connecting the air-drying component, the windproof and ventilation component and the guide component.

[0021] Two air-drying components are respectively arranged on both sides of the cabinet 1, and the air-drying components are composed of a guide part and a push part; The guide part changes the direction of hot air flow by rotating, so that the hot air dries the outside of the cabinet 1 through a preset path under the negative pressure generated by the heat dissipation component; The pushing part sends and receives signals when it rains, and pushes to generate a sliding rotation action, thereby causing the guide part to rotate.

[0022] In this embodiment, refer to Figure 1 and Figure 12 The specific structural implementation scheme of the heat dissipation component is as follows: The heat dissipation component consists of a fan 9 and a heat dissipation port 7. The heat dissipation port 7 is provided on the cabinet 1. The hot air flow inside the cabinet 1 is discharged outward through the heat dissipation port 7. The fan 9 is installed on the heat dissipation port 7. A motor is provided inside the fan 9 to drive the fan 9 to rotate at high speed. The negative pressure generated discharges the hot air flow in the cabinet 1 through the heat dissipation port 7.

[0023] Reference Figures 1-3 , the air-drying component can be implemented as follows: The air-drying assembly is composed of a guide part and a pushing part. The guide part is composed of an air guide box 4, a guide plate 6 and a drying cylinder 3. The air guide box 4 is arranged on the outside of the heat dissipation port 7. The air guide box 4 is fixedly connected to the cabinet 1. The guide plate 6 can rotate on the air guide box 4 to open and close the air guide box 4. One end of the drying cylinder 3 is connected to the bottom of the air guide box 4, and the other end is arranged on the outside of the cabinet 1. When the guide plate 6 rotates to close the air guide box 4, the hot air flow out of the heat dissipation port 7 enters the air guide box 4. Under the action of the fan 9, the hot air flow passes through the air guide box 4 and enters the drying cylinder 3, and finally is ejected from the drying cylinder 3, thereby quickly taking away the dew on the surface of the cabinet 1. The continuous air flow circulation accelerates the evaporation of moisture on the outside of the cabinet 1 to prevent the accumulation of dew from penetrating into the interior of the cabinet 1 or adhering to electrical components, causing short circuit damage to the electrical components. The pushing part is composed of a rain sensor 10, a first gear 16, a first rack 17, an electric telescopic rod 18 and a first slide rail 19. The first gear 16 is rotatably connected to the air guide box 4. The first gear 16 can drive the guide plate 6 to rotate. The first slide rail 19 is fixed to the outside of the air guide box 4. The first rack 17 can slide in the first slide rail 19. The first gear 16 is meshed with the first rack 17. The rain sensor 10 is arranged above the cabinet 1 for monitoring whether it is raining. The electric telescopic rod 18 is fixedly installed in the first slide rail 19. The output end of the electric telescopic rod 18 is fixedly connected to the first rack 17. When the rain sensor 10 detects rain, it will immediately send a signal to the control system, so that the electric telescopic rod 18 drives the first rack 17 to slide upward, and then the first gear 16 drives the guide plate 6 to rotate, so that the air guide box 4 is closed, and then the guide part enters the working state. Example 2:

[0024] The difference from the first embodiment is that, referring to Figure 1 and Figure 4 - Figure 7 , this embodiment also has the following further contents: The rainproof and ventilation assembly is fixedly installed above the cabinet 1, and the rainproof and ventilation assembly consists of a storage part and a rotating and sliding part; The storage part is stored by sliding horizontally inward, forming a ventilation space above the cabinet body 1 to facilitate heat dissipation from the cabinet body 1. The storage part is expanded by sliding horizontally to both sides, forming a rain barrier above both sides of the cabinet body 1, thereby protecting both sides of the cabinet body 1 from rain. The rotary sliding portion generates a sliding motion when rotated, thereby causing the storage portion to be stored or expanded.

[0025] In this embodiment, refer to Figure 1 and Figure 4 - Figure 7 The rainproof and ventilation components can be implemented in the following specific structural implementation plans: The rainproof ventilation assembly is composed of a storage portion and a rotating sliding portion. The storage portion is composed of a cabinet eaves 2, two slides 12 and two slide grooves 24. The cabinet eaves 2 is fixedly mounted on two supports 20. The cabinet eaves 2 is provided with an opening corresponding to the position of the air guide 26 above and below. The two slide grooves 24 are respectively arranged under the cabinet eaves 2. The two slides 12 are respectively slidably connected to the cabinet eaves 2. A plurality of ventilation holes are provided on one side of the slide 12. When the storage portion is in a normal storage state, one side of the ventilation hole of the slide 12 is arranged on the opening of the cabinet eaves 2, which can maintain the heat dissipation and ventilation of the cabinet body 1 and avoid the closed environment above the cabinet body 1 causing the heat of the cabinet body 1 to be difficult to volatilize. When the two slides 12 slide outwards respectively, the ventilation hole sides of the two slides 12 will be stored in the cabinet eaves 2, and the other side of the slide 12 will be unfolded above both sides of the cabinet body 1, forming protection for both sides of the cabinet body 1 to prevent rainwater from invading the interior through the side gaps of the cabinet body 1; The rotating sliding part is composed of two second racks 23 and two second gears 22. The two second gears 22 can rotate on the two supports 20 respectively, and the two second racks 23 can slide on the two slide grooves 24 respectively. When the two second racks 23 slide, they can drive the slide 12 to slide in the cabinet eaves 2. The two second gears 22 are respectively engaged with the two second racks 23. When the second gears 22 rotate, they can drive the second racks 23 to slide, thereby causing the slide 12 to slide to expand or retract. Example 3:

[0026] Reference Figure 2 and Figures 8-12 Compared with the first and second embodiments, in this embodiment: The air guide assembly is provided on the cabinet 1 and is composed of a swinging portion and a reciprocating sliding portion. The swinging portion generates continuous swinging by reciprocating rotation at the air guide port 26, thereby accelerating the external airflow and the internal airflow to circulate through the air guide port 26. When the swinging portion is stationary, it can rotate and reset under the action of elasticity to close. The reciprocating sliding portion rotates and then slides back and forth, thereby driving the swinging portion to rotate back and forth at the air guide port 26 , and a mounting portion is provided on the outer side of the reciprocating swinging portion.

[0027] The reciprocating swinging part is fixedly mounted on the mounting part. The mounting part slides downward after rotating, thereby releasing the control of the reciprocating sliding part on the swinging part and making the swinging part stationary.

[0028] The transmission assembly includes a rotating part and a transmission part. The rotating part can start to rotate under the drive of the pushing part, and the rotating part can drive the sliding rotating part and the installation part to start working through rotation; the transmission part drives the rotating part through the pushing part, and in turn makes the sliding rotating part and the installation part start working.

[0029] In this embodiment, refer to Figures 8-12 The specific structural implementation scheme of the flow guide component is as follows: The guide assembly is composed of a swinging part and a reciprocating sliding part. The swinging part is composed of three fourth gears 30 and three guide plates 27. The three fourth gears 30 can rotate outside the cabinet 1 respectively. The three fourth gears 30 are connected to the cabinet 1 with torsion springs. The three guide plates 27 are provided with waterproof strips on the upper, lower, left and right sides. The three guide plates 27 can rotate at the air guide port 26 respectively. When the three fourth gears 30 rotate back and forth, they can drive the three guide plates 27 to rotate back and forth respectively, so that the guide plates 27 are at the air guide port. The gears 26 are constantly swinging, thereby accelerating the air exchange between the inside and outside of the cabinet 1 through the air guide 26, and enhancing the efficiency of the hot air flow discharge in the cabinet 1. When the three fourth gears 30 are not affected by external force transmission and stop reciprocating rotation, the three guide plates 27 will rotate under the action of the torsion spring and rotate uniformly into a horizontal arrangement. Under the action of the waterproof strips on the guide plates 27, the air guide 26 is completely sealed and blocked, which can effectively prevent rainwater from entering the interior of the cabinet 1 through the air guide 26, ensuring a safe operating environment for the electrical components in the cabinet 1. The reciprocating sliding part is composed of a motor 5, a reciprocating screw rod 11, a slide 31, a fourth rack 32 and a second slide rail 33. The slide 31 is arranged on one side of the cabinet 1, and the motor 5 is fixedly mounted on the slide 31. One end of the reciprocating screw rod 11 is fixedly connected to the transmission shaft of the motor 5, and the other end is rotatably connected to the slide 31. The second slide rail 33 is fixed on the slide 31. The fourth rack 32 can slide on the second slide rail 33. The fourth rack 32 is threadedly connected to the reciprocating screw rod 11. The fourth rack 32 is meshed with the three fourth gears 30. Starting the motor 5 drives the reciprocating screw rod 11 to rotate, so that the fourth rack 32 slides back and forth on the reciprocating screw rod 11 and the second slide rail 33, thereby driving the three fourth gears 30 to rotate reciprocally. When the slide 31 slides downward, it can drive the fourth rack 32 downward, so that the fourth rack 32 disengages from the fourth gear 30, thereby releasing the transmission influence on the fourth gear 30.

[0030] Reference Figure 9 , the installation part can be implemented in the following specific structures: The mounting portion consists of a mounting frame 13, two third racks 34 and two third gears 29. The mounting frame 13 is fixed to the outside of the cabinet 1, and the slide 31 can slide on the mounting frame 13. The two third racks 34 can slide on both sides of the mounting frame 13 respectively. The two third racks 34 are respectively fixed on both sides of the slide 31. The two third gears 29 are respectively arranged on both sides of the mounting frame 13. The two third gears 29 are respectively engaged with the two third racks 34. When the two third gears 29 rotate, they can respectively drive the two third racks 34 to slide downward, thereby causing the mounting frame 13 to drive the reciprocating sliding portion to slide downward.

[0031] Reference Figure 2 、 Figure 3 、 Figure 5 、 Figure 8 andFigure 11 The transmission assembly can be implemented in the following specific structural manner: The transmission assembly consists of a rotating part and a transmission part. The rotating part consists of two first transmission wheels 15, two second transmission wheels 21 and two third transmission wheels 25. The two first transmission wheels 15 are respectively fixed on the two first gears 16, and the two second transmission wheels 21 are respectively fixed on the two second gears 22. The two third transmission wheels 25 can rotate on the cabinet 1. The two third transmission wheels 25 are respectively fixedly connected to the two third gears 29. When the first gear 16 rotates under the push of the first rack 17, it can drive the first transmission wheel 15 to rotate. When the second transmission wheel 21 rotates, it can drive the second gear 22 to rotate. When the third transmission wheel 25 rotates, it can drive the third gear 29 to rotate, thereby causing the third rack 34 to slide.

[0032] The transmission part consists of two first belts 14 and two second belts 28. The first belt 14 is wound around the outside of the first transmission wheel 15 and the second transmission wheel 21, and the second belt 28 is wound around the outside of the first transmission wheel 15 and the third transmission wheel 25. When the first transmission wheel 15 rotates under the rotation of the first gear 16, the second transmission wheel 21 can be driven to rotate through the first belt 14, thereby rotating the second gear 22. At the same time, the third transmission wheel 25 is driven to rotate through the second belt 28, and the third transmission wheel 25 drives the third gear 29 to rotate.

[0033] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
