Description

Technical Field

[0001] This invention relates to the field of power cabinet technology, specifically an outdoor rainproof power cabinet. Background Technology

[0002] A power distribution cabinet is a device for centralized control and distribution of electricity. Its main function is to collect electrical energy from different power sources and distribute it to the equipment that needs power. Simultaneously, it isolates and protects different circuits to ensure the safe and stable operation of the power grid. Therefore, power distribution cabinets are widely used in large buildings, factories, power plants, and other similar locations.

[0003] For outdoor power distribution cabinets, good rainproof and heat dissipation functions are required to cope with harsh outdoor weather.

[0004] According to Chinese Patent Publication No. CN111817147B, an outdoor rainproof power cabinet utilizes airflow to drive a rotating impeller during wind and rain. This causes a vibrating block to move back and forth, continuously striking a generator plate. Under the piezoelectric effect, the generator plate vibrates and generates electricity, energizing an electromagnet and causing a sealing column to rotate. This blocks the cylindrical hole, preventing rainwater from entering the cabinet. When there is no rain, the electromagnet is de-energized, and the sealing column opens the cylindrical hole under the action of a torsion spring, allowing air to exchange between the inside and outside of the power cabinet, ensuring its heat dissipation performance. By using a closed coil instead of generator plate vibration to generate electricity, energy loss during impeller rotation is greatly reduced, improving energy conversion efficiency and enabling the electromagnet to generate stronger magnetism, thus improving the rainproof performance of the device. By incorporating components such as a pump cylinder, a second iron plate, and a one-way inlet and one-way return pipe, coolant can circulate unidirectionally along the one-way inlet and return pipes during impeller rotation, further improving the heat dissipation performance of the power cabinet.

[0005] While this patent achieves significant results in heat dissipation, its impeller design is essentially equivalent to a traditional cooling fan. However, this design is relatively simple and lacks the ability to adjust the airflow direction. Therefore, it cannot effectively change the direction of airflow, thus limiting the rapid dissipation of heat inside the cabinet. To further improve heat dissipation efficiency, it is necessary to improve the impeller structure to achieve flexible airflow control, thereby accelerating the heat dissipation process inside the cabinet.

[0006] Therefore, it is necessary to design a practical outdoor rainproof power cabinet. Summary of the Invention

[0007] The purpose of this invention is to provide an outdoor rainproof power cabinet to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an outdoor rainproof power cabinet, comprising: Cabinet; A heat dissipation component is installed inside the cabinet and is connected to the top of the inner wall of the cabinet. Adjustment components are installed between the top of the cabinet's inner wall and the heat dissipation components; An auxiliary component is installed inside the cabinet and is connected to the adjustment component. The rainproof component is located at the ventilation vent on the side of the cabinet.

[0009] According to the above technical solution, the cabinet is hinged to the front of the cabinet and a base is fixedly installed on the bottom of the cabinet. The base fixedly installed on the bottom of the cabinet can not only provide stable support for the cabinet, but also prevent the bottom of the cabinet from directly contacting the ground. This indirectly enables the bottom of the cabinet to effectively prevent moisture, thus preventing the electrical components inside the cabinet from getting damp and affecting their service life.

[0010] According to the above technical solution, a heat dissipation vent is provided on the side of the cabinet, and a dustproof frame is fixedly installed on the inner wall of the cabinet. The dustproof frame is positioned corresponding to the heat dissipation vent. The dustproof frame installed at the heat dissipation vent can effectively dissipate heat, allowing the heat generated by the electrical components inside the cabinet to dissipate from there.

[0011] According to the above technical solution, the heat dissipation component includes: The motor is fixedly installed on the top surface of the cabinet and the top of the inner wall of the cabinet. A connecting shaft is fixedly installed on the output end of the motor. A first connecting block and a second connecting block are connected by a pin. The top of the first connecting block is fixedly installed to the bottom of the connecting shaft. The mounting shaft is fixedly installed at its top end to the bottom of the second connecting block, and fan blades are fixedly installed on the outer wall of the lower end of the mounting shaft.

[0012] According to the above technical solution, the adjustment component includes: A cover is installed outside the motor, and the top of the cover is fixedly installed to the top of the inner wall of the cabinet; A circular plate, the outer wall of which is fixedly installed to the inner wall of the lower end of the cover, and the inner wall of the circular plate has an arc-shaped notch; An auxiliary plate is fixedly sleeved on the outer wall of the mounting shaft. The outer wall of the auxiliary plate has a protruding feature located within an arc-shaped notch.

[0013] According to the above technical solution, the auxiliary component includes: The tube body is fixedly installed at one end to the inner wall of the cabinet. A piston is slidably provided on the inner wall of the tube body. A piston rod is fixedly installed on the side of the piston. The end of the piston rod away from the piston moves through the cover and the circular plate in sequence, extending into one of the arc-shaped notches. An arc-shaped block is fixedly installed on its outer wall to the end of the piston rod, and the inner surface of the arc-shaped block is pressed against the protrusion of the auxiliary plate. An L-shaped tube is provided, with one end connected to the outer wall of the tube body, and the outer wall of the lower end of the L-shaped tube has an upward-facing ventilation hole.

[0014] According to the above technical solution, a spring is installed inside the tube. One end of the spring is fixedly installed to the inner wall of the cabinet, and the other end of the spring is fixedly installed to the side of the piston. The spring, in conjunction with the heat dissipation component and the adjustment component, can drive the piston rod to move back and forth, thereby generating gas flow.

[0015] According to the above technical solution, the outer wall of the L-shaped tube is provided with a T-shaped tube, and the outer wall of the T-shaped tube has a ventilation opening facing the dustproof frame. This allows some airflow to pass through the T-shaped tube and blow towards the dustproof frame, avoiding dust blockage and affecting the heat dissipation effect of the dustproof frame.

[0016] According to the above technical solution, the rainproof component includes: A rain cover with ventilation holes on the bottom surface is fixedly installed on the side of the cabinet. A connecting rod is fixedly installed at one end to the side of the rain cover, and a retaining ring is fixedly installed at the other end of the connecting rod away from the rain cover. The first and second arc-shaped springs are positioned vertically and are fixedly installed on the inner wall of the heat dissipation vent. The sides of the first and second arc-shaped springs that are close to each other have a notch, which is engaged with a retaining ring.

[0017] According to the above technical solution, the retaining ring is made of spring material and has deformation properties, which allows the retaining ring to be easily inserted and removed between the first arc-shaped spring and the second arc-shaped spring.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. This invention effectively achieves heat dissipation inside the cabinet by setting up a heat dissipation component. In particular, by using a pin-connected connection between the first and second connecting blocks, the fan blades can undergo slight angle changes as the heat dissipation component rotates during operation. This optimizes the airflow path, accelerates the diffusion of airflow, and ensures that all corners inside the cabinet are cooled quickly and evenly. In this way, not only is the heat dissipation efficiency significantly improved, but the temperature inside the cabinet is also ensured to drop evenly, further enhancing the stability and reliability of the system.

[0019] 2. This invention, through the combination of a circular plate and an auxiliary plate, especially the auxiliary plate being embedded in the arc-shaped notch of the circular plate in a protruding shape, achieves an innovative structure that allows the auxiliary plate to effectively compress against the circular plate when the mounting shaft is driven to rotate. This mechanism not only significantly expands the angle adjustment range of the fan blades but also greatly promotes the efficiency and directionality of airflow by optimizing the windward angle of the fan blades, further accelerating heat dissipation. Therefore, this design not only enhances the performance of the heat dissipation components but also significantly improves the heat dissipation speed inside the cabinet, ensuring the efficient and stable operation of the equipment.

[0020] 3. This invention, through the extrusion and cooperation of the arc-shaped block and the convex auxiliary plate, can effectively drive the piston rod to move the piston back and forth within the tube. This process generates a directional airflow, which enters the L-shaped pipe and blows onto the surface of the electrical components through the ventilation holes. This design not only enhances the air convection effect but also ensures that the airflow can directly act on the heat-generating area of ​​the electrical components, greatly promoting the rapid dissipation of internal heat. With the synergistic effect of the heat dissipation components, this innovative design significantly accelerates the heat dissipation speed, effectively improves the working efficiency and stability of the electrical components, and provides a solid guarantee for the long-term reliable operation of the equipment.

[0021] 4. This invention effectively provides rain protection by using a rain cover, ensuring that rainwater cannot penetrate the cabinet interior, thus avoiding damage or performance degradation of electrical components caused by rainwater. In addition, the combination of a retaining ring and a first and second arc-shaped spring greatly facilitates the installation and removal of the rain cover. This design not only simplifies the installation and disassembly process but also ensures a stable connection between the rain cover and the cabinet, making maintenance or replacement of the rain cover exceptionally easy and quick, greatly improving the convenience and efficiency of operation.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figure 1-8 The present invention provides a technical solution: an outdoor rainproof power cabinet, comprising: Cabinet 1; The cabinet 1 has a hinged door 2 on the front and a base 3 fixedly installed on the bottom. The base 3 fixedly installed on the bottom of the cabinet 1 can not only provide stable support for the cabinet 1, but also prevent the bottom of the cabinet 1 from directly contacting the ground. This indirectly enables the bottom of the cabinet 1 to effectively prevent moisture, thus preventing the electrical components inside the cabinet 1 from getting damp and affecting their service life. The side of the cabinet 1 is provided with a heat dissipation vent 4, and a dustproof frame 5 is fixedly installed on the inner wall of the cabinet 1. The dustproof frame 5 is set in a position corresponding to the heat dissipation vent 4. The dustproof frame 5 installed at the heat dissipation vent 4 can play an effective heat dissipation role, so that the heat generated by the electrical components inside the cabinet 1 can be dissipated from there. A heat dissipation component 61 is installed inside the cabinet 1, and the heat dissipation component 61 is connected to the top of the inner wall of the cabinet 1. Adjustment component 7 is installed between the top of the inner wall of cabinet 1 and heat dissipation component 61; Auxiliary component 8 is installed inside cabinet 1, and is connected to adjustment component 7; Rainproof component 9 is located at the ventilation opening 4 on the side of cabinet 1.

[0026] Heat dissipation component 6 includes: The top surface of the motor 61 is fixedly installed on the top of the inner wall of the cabinet 1, and the output end of the motor 61 is fixedly installed with a connecting shaft 62. The first connecting block 63 and the second connecting block 64 are connected by a pin. The top of the first connecting block 63 is fixedly installed to the bottom of the connecting shaft 62. The mounting shaft 65 is fixedly installed at its top end to the bottom of the second connecting block 64, and a fan blade 66 is fixedly installed on the outer wall of the lower end of the mounting shaft 65.

[0027] In the specific implementation process, starting the motor 61 can make the connecting shaft 62 rotate. Due to the first connecting block 63 and the second connecting block 64, the mounting shaft 65 can rotate during the rotation of the connecting shaft 62. The fan blade 66 can rotate under the rotation of the mounting shaft 65 to achieve the purpose of heat dissipation. Here, since the first connecting block 63 and the second connecting block 64 are connected by a pin, there is a slight deflection during the rotation of the mounting shaft 65. This can make the fan blade 66 have a slight angle change, which speeds up the speed at which the air diffuses to various parts of the cabinet.

[0028] Example 2: Based on the above implementation scheme, the adjustment component 7 includes: The cover 71 is located outside the motor 61, and the top of the cover 71 is fixedly installed to the top of the inner wall of the cabinet 1. The outer wall of the circular plate 72 is fixedly installed to the inner wall of the lower end of the cover 71, and the inner wall of the circular plate 72 has an arc-shaped notch 74. The auxiliary plate 73 is fixedly sleeved on the outer wall of the mounting shaft 65. The outer wall of the auxiliary plate 73 has a protrusion, which is located in the arc-shaped notch 74.

[0029] In the specific implementation process, the auxiliary plate 73 can be rotated together when the mounting shaft 65 rotates. Since the auxiliary plate 73 is convexly set in the arc-shaped notch 74 of the circular plate 72, it can be squeezed against the inner wall of the arc-shaped notch 74 during the rotation of the auxiliary plate 73. Then the angle between the first connecting block 63 and the second connecting block 64 can be increased, and finally the angle range of the fan blade 66 can be increased, thereby accelerating the heat dissipation speed again.

[0030] Example 3: Based on the above implementation scheme, auxiliary component 8 includes: The tube body 81 is fixedly installed at one end to the inner wall of the cabinet 1. A piston 84 is slidably installed on the inner wall of the tube body 81. A piston rod 82 is fixedly installed on the side of the piston 84. The end of the piston rod 82 away from the piston 84 moves through the cover body 71 and the circular plate 72 in sequence, and extends into one of the arc-shaped notches 74. The tube body 81 is equipped with a spring 85. One end of the spring 85 is fixedly installed to the inner wall of the cabinet 1, and the other end of the spring 85 is fixedly installed to the side of the piston 84. The spring 85, together with the heat dissipation component 6 and the adjustment component 7, can drive the piston rod 82 to move the piston 84 back and forth, thereby generating gas flow. The outer wall of the arc-shaped block 83 is fixedly installed to the end of the piston rod 82, and the inner surface of the arc-shaped block 83 is pressed against the protrusion of the auxiliary plate 73. The L-shaped tube 86 is connected at one end to the outer wall of the tube body 81, and the outer wall of the lower end of the L-shaped tube 86 has an upward-facing ventilation hole.

[0031] In the specific implementation process, the arc-shaped block 83 and the auxiliary plate 73 are squeezed together in a raised shape. During the rotation of the auxiliary plate 73, the arc-shaped block 83 is squeezed together, which then drives the piston rod 82 to move, so that the piston 84 moves in the tube body 81 and generates airflow. This airflow enters the L-shaped tube 86 and finally blows out of the ventilation hole to the electrical components, accelerating the heat dissipation inside the electrical components. In conjunction with the heat dissipation component 6, the heat dissipation speed is accelerated.

[0032] In this embodiment, the outer wall of the L-shaped tube 86 is provided with a T-shaped tube 87. The outer wall of the T-shaped tube 87 has a ventilation opening facing the dustproof frame 5. This allows some airflow to pass through the T-shaped tube 87 and be blown toward the dustproof frame 5, preventing dust from clogging the frame and affecting its heat dissipation.

[0033] Example 4: Based on the above implementation scheme, the rainproof component 9 includes: Rain cover 91 has ventilation holes on the bottom surface and is fixedly installed on the side of cabinet 1. One end of the connecting rod 92 is fixedly installed to the side of the rain cover 91, and the other end of the connecting rod 92 away from the rain cover 91 is fixedly installed with a retaining ring 93. The first arc-shaped spring piece 94 and the second arc-shaped spring piece 95 are positioned vertically, and both the first arc-shaped spring piece 94 and the second arc-shaped spring piece 95 are fixedly installed on the inner wall of the heat dissipation port 4. The side of the first arc-shaped spring piece 94 and the second arc-shaped spring piece 95 that are close to each other have a notch, which is engaged with the retaining ring 93.

[0034] In the specific implementation process, the rain cover 91 can achieve the function of rain protection, preventing rainwater from entering the cabinet 1 and affecting the use of electrical components. At the same time, the setting of the retaining ring 93 and the first arc-shaped spring 94 and the second arc-shaped spring 95 can facilitate the installation and removal of the rain cover 91, which is extremely convenient.

[0035] In this embodiment, the retaining ring 93 is made of a spring material with deformation properties, which allows the retaining ring 93 to be easily inserted into and removed between the first arc-shaped spring 94 and the second arc-shaped spring 95.

[0036] Working principle: After starting the motor 61, the connecting shaft 62 rotates accordingly. The rotation of the connecting shaft 62 causes the first connecting block 63 to rotate, which in turn causes the second connecting block 64 to rotate. The rotation of the second connecting block 64 then rotates the mounting shaft 65, thereby driving the fan blades 66 to rotate, achieving a heat dissipation effect. Specifically, the first connecting block 63 and the second connecting block 64 are connected by a pin, allowing the mounting shaft 65 to produce a slight offset during rotation. This design gives the fan blades 66 the ability to change angle slightly, accelerating the diffusion speed of air within the cabinet 1 and ensuring a more uniform heat dissipation effect. Simultaneously, the rotation of the mounting shaft 65 also drives the auxiliary plate 73 to rotate synchronously. Because the auxiliary plate 73 is protruding and embedded in the arc-shaped notch 74 of the circular plate 72, during rotation, the auxiliary plate 73 and the inner wall of the arc-shaped notch 74 are pressed together. This interaction further increases the pressure between the first connecting block 63 and the second connecting block 64. The angle between the fan blades 66 and the auxiliary plate 73 is increased, thus expanding the angle adjustment range of the fan blades 66 and further improving the heat dissipation efficiency. More ingeniously, the squeezing action between the arc-shaped block 83 and the protruding part of the auxiliary plate 73 during the rotation of the auxiliary plate 73 will squeeze the arc-shaped block 83, thereby pushing the piston rod 82 to move, so that the piston 84 reciprocates within the tube body 81. The setting of the spring 85, together with the heat dissipation component 6 and the adjustment component 7, ensures that the piston rod 82 can stably drive the piston 84 to reciprocate, thereby generating a continuous airflow. This airflow is guided into the L-shaped tube 86 and finally blown directionally from the ventilation hole to the electrical components, greatly promoting the dissipation of heat inside the electrical components. With the combined action of the heat dissipation component 6, this innovative design not only significantly accelerates the heat dissipation speed, but also ensures that the electrical components can operate in a more stable and efficient environment. At the same time, some airflow will enter the T-shaped tube 87 and finally blow onto the dust frame 5 to prevent dust from clogging it and affecting the heat dissipation effect.
