Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, and in particular to a low-voltage power distribution cabinet assembly. Background Art

[0002] The existing method for waterproofing the cabinet assembly of the low-voltage distribution cabinet is to place a hydraulic cylinder, a telescopic rod, a connecting rod, a water level sensor, an oil tank and an oil pump. When rain is generated near the device and the rain submerges the water level sensor, the water level sensor sends a signal to the KS02Y controller. After the KS02Y controller processes and analyzes the information, it starts the oil pump. The oil pump starts to extract the hydraulic oil in the oil tank and transports it to the hydraulic cylinder through the oil pipe. The piston in the hydraulic cylinder moves after being pushed by the hydraulic oil. The movement of the piston pushes the telescopic rod to move, thereby driving the cabinet to move, so that the equipment inside the cabinet will not be penetrated by water, thereby increasing the service life of the equipment, reducing losses, and reducing the cost of use.

[0003] The increase in the cabinet height in the above device can provide a certain degree of waterproof effect, because it can increase the difficulty of water entering the cabinet. However, even if the cabinet height is increased, if the water continues to rise, it will eventually penetrate through the joint between the cabinet and the cabinet door. This is mainly because water has a certain pressure. When the water pressure exceeds the sealing performance of the joint between the cabinet and the cabinet door, water will penetrate into the cabinet along these gaps. Therefore, a low-voltage distribution cabinet assembly is required. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The low-voltage distribution cabinet assembly refers to the main structural components of the low-voltage distribution cabinet, including the cabinet, cabinet door, internal partitions, connectors, etc. These components together form a complete low-voltage distribution cabinet, which is used to install, protect and connect distribution equipment such as circuit breakers, contactors, motor protectors, etc.

[0024] Example 1

[0025] In existing installations, the increase in cabinet height can provide a certain degree of waterproofing because it can increase the difficulty of water entering the cabinet. However, even if the cabinet height is increased, if the water continues to rise, it will eventually penetrate through the cabinet and the door. This is mainly because water has a certain pressure. When the water pressure exceeds the sealing performance of the cabinet and the door, it will cause water to penetrate into the cabinet through these gaps. Figure 1-Figure 4 The embodiment provides a low-voltage power distribution cabinet assembly, including a cabinet 1 and a cabinet door 2 that moves on the surface of the cabinet 1 through hinges, two ventilation windows 3 are symmetrically provided on both sides of the cabinet 1, a sealing ring 6 is fixedly connected to the surface of the cabinet 1, and the inside of the sealing ring 6 is hollow. A sealing groove 7 adapted to the sealing ring 6 is provided on the surface of the cabinet door 2, a mounting seat 4 is fixedly connected to the bottom of the cabinet 1, and an anti-seepage component 5 is provided inside the mounting seat 4 for controlling the expansion and contraction of the sealing ring 6 in the sealing groove 7 according to the water level.

[0026] refer to Figure 1 As shown, at the joint of the cabinet body 1 and the cabinet door 2, there is usually a certain sealing performance to prevent dust, moisture and other impurities from entering the interior of the cabinet body 1. However, even if these seals are good, it is difficult to completely prevent water from penetrating, especially when the water pressure is high. Water has pressure, which is due to the intermolecular interaction force and gravity of water. When water is subjected to external pressure, it will find a way to release the pressure. This means that if there are any tiny defects or pores, water will penetrate into the interior of the cabinet body 1 along these gaps. In order to increase the self-repairing protection function of the sealing ring 6, the following settings are made. The anti-seepage component 5 includes a floating plate 51 arranged inside the mounting seat 4. The bottom of the floating plate 51 is fixedly connected with a buoyancy bag 52. When the water level rises, the effect of buoyancy will also increase. According to the Archimedes principle, the magnitude of the buoyancy is equal to the weight corresponding to the volume displaced by the liquid, that is, the buoyancy is proportional to the volume of the liquid. Therefore, as the water level rises, the thrust of the liquid on the buoyancy bag 52 will also increase, and the buoyancy bag 52 will drive the floating plate 51 upward. Two slide plates 53 are symmetrically fixedly connected to the two ends of the floating plate 51, and the tops of the two slide plates 53 are fixedly connected with elastic air-filling bags 54. A floating groove is opened on the side of the mounting seat 4. The slide plate 53 is slidably sleeved inside the floating groove, and the two ends of the elastic air-filling bag 54 are respectively fixedly connected to the floating groove and the slide plate 53. The circumferential surface of the top of the elastic air-filling bag 54 is fixedly connected with an air-filling pipe 55 fixedly connected to the inside of the sealing ring 6. As the water level rises, the slide plate 53 moves up to squeeze the elastic air-filling bag 54. When the elastic air-filling bag 54 is squeezed, the gas inside it will be input into the sealing ring 6 from the air-filling pipe 55, causing it to expand and fit tightly with the inner cavity of the sealing groove 7. The more gas is filled in the sealing ring 6, the more the amount of gas filled in the sealing ring 6 is proportional to the water level, thereby providing a better waterproof effect, and a stronger sealing effect, further preventing water from seeping into the cabinet body 1 from the closing point of the cabinet body 1 and the cabinet door 2.

[0027] Example 2

[0028] Based on Example 1, Figure 1-Figure 4, usually, the ventilation windows 3 on the side of the cabinet 1 in the prior art are designed to prevent water from directly pouring in. These windows are usually designed with small holes or partitions to allow air to flow freely while preventing water or other liquids from entering. However, in order to prevent the ventilation windows 3 from being damaged and causing water to enter the interior of the cabinet 1 through the windows, the following protective measures are specially provided. Two ends of the two slides 53 opposite to each other are symmetrically provided with two window closing assemblies 8 for simultaneously closing the two ventilation windows 3 under the synchronous drive of the anti-seepage assembly 5. The window closing assembly 8 includes a connecting rod 81 fixed to the top of the slide 53, and a window closing plate 82 is fixedly connected to the top of the connecting rod 81. The size of the window closing plate 82 is larger than the size of the ventilation window 3, and the window closing plate 82 is tightly attached to the side opposite to the cabinet 1. When the slide 53 moves up, it will drive the connecting rod 81 and the window closing plate 82 on its top to move up, and gradually seal the ventilation window 3 according to the height of the water level, so as to prevent water from entering the interior of the cabinet 1 through the ventilation window 3, causing the interior of the cabinet 1 to be damp, corroded or even damaged, thereby affecting the service life and safety of the cabinet 1.

[0029] refer to Figure 1-Figure 2 As shown, the electronic equipment inside the cabinet 1 usually generates a certain amount of heat, which needs to be dissipated during normal operation to maintain a stable working temperature. When the ventilation window 3 is sealed, the air flow is blocked, resulting in the restriction of air circulation inside the cabinet 1, so that the heat cannot be effectively dissipated, resulting in an increase in the temperature inside the cabinet 1, which will affect the performance and life of the equipment. In order to maintain a good heat dissipation effect inside the cabinet 1, the following settings are made: two skylights 31 are symmetrically opened from left to right on the top of the cabinet 1, and a ventilation component 83 is provided on the top of the cabinet 1 for opening the two skylights 31 at the same time to cool down the temperature inside the cabinet 1 under the synchronous drive of the window closing component 8. The ventilation component 83 includes a fan fixed on the window closing component 8. The lifting plate 831 on the surface of the plate 82, the side of the top of the lifting plate 831 is movably connected with a movable plate 832, the end of the movable plate 832 away from the lifting plate 831 is movably connected with a top sealing plate 833, the bottom of the top sealing plate 833 is fixedly connected to a limiting block, and the top of the cabinet 1 is provided with a limiting groove for the horizontal sliding of the limiting block, the bottom of the top sealing plate 833 is in close contact with the top of the cabinet 1, and the upward movement of the window closing plate 82 will drive the lifting plate 831 to move upward, and the upward movement of the lifting plate 831 will cause the movable plate 832 to push the top sealing plate 833 to slide, and then gradually open the skylight 31 on the top of the cabinet 1 to achieve ventilation and heat dissipation, so that the opening degree of the skylight 31 is proportional to the closing degree of the ventilation window 3, thereby maintaining the original heat dissipation effect.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
