Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and particularly to a power distribution cabinet with shock absorption and heat dissipation functions. Background Art

[0002] Multiple inverters are installed in the power distribution cabinet and placed outdoors. Subject to direct sunlight and relatively dense cabinets, the temperature inside the power distribution cabinet remains high, which affects the working life of the components inside the cabinet. The working temperature of the components can be guaranteed by the designed mechanical ventilation.

[0003] The patent with the publication number CN113054549B discloses a multi-dimensional shock-absorbing intelligent power distribution cabinet, including a cabinet body. A blower is provided on the lower end surface of the top plate of the cabinet body. First ventilation openings are opened at the upper ends of the left and right side plates of the cabinet body. Second ventilation openings are opened in the upper middle parts of the left and right side plates of the cabinet body. Third ventilation openings are opened at the lower ends of the left and right side plates of the cabinet body. Self-closing plugging mechanisms are arranged outside the second ventilation openings and the third ventilation openings. Sealing plate auxiliary switch mechanisms for pushing open the self-closing plugging mechanisms are arranged on the left and right sides of the inner cavity of the cabinet body. A driving mechanism for driving the sealing plate auxiliary switch mechanisms is arranged above the top plate of the cabinet body. Shock-absorbing seats are arranged at the lower end of the bottom plate of the cabinet body. The present invention has good heat dissipation effect, and can adjust the structure according to the internal temperature of the cabinet body and whether the external temperature drops, etc., and the seismic effect is also significantly improved.

[0004] However, there are still some deficiencies in the above during actual use: 1. During daily heat dissipation, external air enters from the third ventilation opening and exits from the second ventilation opening and the first ventilation opening. However, in extreme windy and rainy weather, after the second ventilation opening and the third ventilation opening are blocked, only the first ventilation opening plays a role in heat dissipation. Although the first ventilation opening is completely shielded by the rain cover on the top of the cabinet body and has the lowest probability of water ingress, the ventilation effect will be greatly reduced; 2. In extreme weather, the third ventilation opening is completely closed, and no cold air enters the power distribution cabinet, which greatly affects the heat dissipation effect. Therefore, a power distribution cabinet with shock absorption and heat dissipation functions is proposed to solve the above problems. Summary of the Invention

The inner wall of each dust collection chamber is fixedly connected with a ventilation hose. Ventilation holes are provided on both sides of each main intake net plate, and the ventilation holes are opened on the inner wall of the power distribution cabinet body. One end of each ventilation hose away from the dust collection chamber is communicated with the ventilation holes.

[0014] In the above-mentioned power distribution cabinet with shock absorption and heat dissipation functions, the bottom outer wall of each top sealing plate is fixedly connected with a scraper, the outer wall of each scraper is fixedly connected with a push rod, the outer walls on both sides of each intake chamber are fixedly connected with fixing frames, a sliding plate one is slidably connected to the outer wall of each fixing frame, and a spring one is fixedly connected between each fixing frame and the sliding plate one.

[0015] Compared with the existing technology, the advantages of the present power distribution cabinet with shock absorption and heat dissipation functions are as follows:

[0016] 1. When the two closing plates one are closed, the closing plate one forms a closure on the side of the intake chamber. At the same time, the second rack on the closing plate one drives the first gear to rotate, and the first gear drives the first rack to move, thereby driving the two top sealing plates to open, so that the intake channel changes from the side of the intake chamber to the upper part, better avoiding rainwater from entering the power distribution cabinet body;

[0017] 2. When the intake channel is switched, the rotation of the first gear will also drive the rotation of the first bevel gear and the second bevel gear, so that the second bevel gear drives the intake chamber to rotate through the second shaft rod and the first belt. The intake chamber drives the fourth gear to rotate through the second belt. The rotation of the fourth gear also drives the fourth rack and the connecting rod two to move downward, so that the telescopic rain shield extends, making the side wall of the intake hood longer and having a better wind and water protection effect;

[0018] 3. During the opening process of the top sealing plate, the connecting rod one will drive the dust collection chamber and the brush barrel to move to both sides. During the movement of the fixing rod two, it will rotate due to the meshing of the second gear and the third rack, so that the brush barrel can clean the dust attached to the top intake net plate. At the same time, since the ventilation hose is connected to the dust collection chamber, the dust on the brush barrel is scraped off by the dust collection chamber and adsorbed by the negative pressure of the ventilation hose. A filter screen is provided at the connection between the ventilation hose and the dust collection chamber to block dust from entering the inside of the ventilation hose. When the top sealing plate is completely opened, the top sealing plate will squeeze the ventilation hose against the inner wall of the intake hood, causing the airflow inside the ventilation hose to be interrupted. At the same time, the retraction of the closing plate one will contact the bottom plate, causing the lower part of the dust collection chamber to open, thus facilitating the discharge of the dust inside the dust collection chamber;

[0019] 4. During the switching of the air intake channel, the movement of the top sealing plate will drive the scraper to clean the dust on one side of the main air intake mesh plate. When the push rod moves to the edge, the door plate can be pushed open to facilitate the discharge of dust on the scraper. Cold air can enter the power distribution cabinet body faster from the top air intake mesh plate and the main air intake mesh plate;

[0020] To summarize, the present invention can change the air intake channel in bad weather by adjusting the air intake mechanism, and increase the side wall length of the air intake hood to make it have better windproof and waterproof effects. At the same time, the brush barrel can clean the dust attached to the top air intake mesh plate, and store the dust and then discharge it, while driving the scraper to clean the dust on one side of the main air intake mesh plate. Cold air can enter the distribution cabinet body from the top air intake mesh plate and the main air intake mesh plate faster. The air outlet mechanism is adjusted in a linked manner so that the air baffle and the side baffle cover the air outlet cover to avoid splashing of rainwater. There is no need to set up additional air outlets, thereby ensuring the heat dissipation effect on rainy days. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The specific working principle and use method of the present invention are explained in detail below: when in use, the motor 9 is turned on to drive the fan blades 8 to rotate, and cold air enters from the air inlet hood 3 and is discharged from the air outlet 7, thereby taking away the heat in the distribution cabinet body 1. A rain sensor is arranged on the top of the top cover 5. When the rain sensor detects rain, the two telescopic rods 26 inside will retract, so that the two sliders 24 slide along the inclined surface of the inclined slide plate 25, and then the two sliders 24 drive the sealing plate 23 to close, and the two sealing plates 23 drive the two sliding baffles 18 to close through the connecting plate 22, so that the side of the air inlet hood 3 is composed of the fixed plate 3 17 and the sliding baffle 18 to form a complete baffle, and at the same time, the closing of the sliding baffle 18 will pull the traction rope 13 on the connecting block 19, and the traction rope 13 will pull the air outlet baffle 4, so that the air outlet baffle 4 and the side baffles 14 cover the air outlet 7 to avoid splashing of rainwater. On sunny days, the opening of the air outlet baffle 4 can make the gas emitted from the air outlet 7 escape better.

[0049] When the two sealing plates 23 are closed, the sealing plates 23 seal the side of the air inlet chamber 30, and at the same time, the second rack 64 on the sealing plate 23 drives the first gear 44 to rotate, and the first gear 44 drives the first rack 32 to move, thereby driving the two top sealing plates 31 to open, so that the air inlet channel changes from the side of the air inlet chamber 30 to the top, which better prevents rainwater from entering the distribution cabinet body 1. At the same time, in the process of opening the top sealing plate 31, the connecting rod 43 will drive the dust collecting chamber 48 and the brush cylinder 54 to move to both sides, and the fixed rod 2 53 will rotate during the movement due to the meshing of the second gear 55 and the third rack 56, so that The brush barrel 54 can clean the dust attached to the top air inlet mesh plate 33. At the same time, since the ventilation hose 37 is connected to the dust collecting chamber 48, the dust on the brush barrel 54 is scraped off by the dust collecting chamber 48 and then absorbed by the negative pressure of the ventilation hose 37. A filter is provided at the connection between the ventilation hose 37 and the dust collecting chamber 48 to prevent dust from entering the interior of the ventilation hose 37. When the top sealing plate 31 is fully opened, the top sealing plate 31 will squeeze the ventilation hose 37 with the inner wall of the air inlet hood 3, so that the air flow inside the ventilation hose 37 is interrupted. At the same time, the sealing plate 23 retracts to contact the bottom plate 59, so that the bottom of the dust collecting chamber 48 is opened, thereby facilitating the discharge of dust inside the dust collecting chamber 48.

[0050] While the intake passage is being switched, the rotation of the first gear 44 also drives the rotation of the first bevel gear 45 and the second bevel gear 46, causing the second bevel gear 46 to drive the rotation of the intake chamber 30 through the second shaft rod 47 and the first belt 40. The intake chamber 30 drives the rotation of the fourth gear 62 through the second belt 63. The rotation of the fourth gear 62 also drives the fourth rack 61 and the second connecting rod 34 to move downward, thereby causing the telescopic rain shield 16 to extend, making the side wall of the intake hood 3 longer and having a better wind and waterproof effect. At the same time, during the process of switching the intake passage, the movement of the top sealing plate 31 drives the scraper 49 to clean the dust on one side of the main intake mesh plate 35. When the push rod 51 moves to the edge, it can push open the door panel 2, facilitating the discharge of the dust on the scraper 49. Cold air can enter the power distribution cabinet body 1 more quickly from the top intake mesh plate 33 and the main intake mesh plate 35. Also, the telescopic rod 26 can be controlled to expand and contract to achieve the effect of regularly cleaning the main intake mesh plate 35.

[0051] Further explanation: For the above fixed connection, unless otherwise clearly specified and limited, it should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0052] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
