Technical Field
[0001] The utility model relates to the technical field of switch cabinets, and particularly to an intelligent low-voltage switch cabinet. Background Technique
[0002] An intelligent low-voltage switch cabinet is a kind of power equipment, which mainly controls and protects the low-voltage circuit by controlling components such as switches, transformers, power supplies, and signal protections; various electrical equipment and intelligent control systems are installed in the intelligent low-voltage switch cabinet, and these devices are very sensitive to moisture. Without a good waterproof design, it is very likely to cause equipment short circuits, damage, or even failures.
[0003] The Chinese utility model patent with the publication number CN219371727U discloses an intelligent low-voltage switch cabinet, including a waterproof mechanism. The waterproof layer in the waterproof bottom plate of the waterproof mechanism isolates moisture to a certain extent, and at the same time, the adsorption sponge layer quickly adsorbs moisture to achieve a waterproof effect. However, in some areas during the rainy season, the rainfall is relatively large and water accumulation is likely to occur. Although the waterproof bottom plate and the adsorption sponge layer can achieve a certain waterproof effect, when there is a lot of rain, the rainfall accumulation is very easy to overflow the waterproof bottom plate and enter the equipment interior along the heat dissipation holes, making the adsorption sponge layer reach saturation, thereby affecting the normal operation of the equipment. Summary of the Utility Model
[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and provide an intelligent low-voltage switch cabinet.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] An intelligent low-voltage switch cabinet includes a cabinet body. Ventilation channels are opened on two opposite side walls of the cabinet body, and a waterproof mechanism is arranged in the ventilation channels to prevent rainwater from entering.
[0007] The waterproof mechanism includes a first waterproof plate, which is arranged in the ventilation channel. A second waterproof plate with the function of sliding up and down is arranged on one side of the first waterproof plate. The second waterproof plate and the first waterproof plate are communicated through a number of ventilation components. The number of ventilation components is divided into multiple rows and distributed from top to bottom in sequence, dividing the surfaces of the first waterproof plate and the second waterproof plate into multiple ventilation areas and sealing areas. The ventilation areas and the sealing areas are staggered. The width of the ventilation area is smaller than the width of the sealing area between two adjacent ventilation areas, so that the second waterproof plate uses its own sealing area to seal the ventilation area on the first waterproof plate, playing the role of closing the ventilation components.
[0008] The waterproof mechanism also includes a detection component for detecting the moving distance of the second waterproof plate.
[0009] Further, the ventilation component includes a first ventilation hole distributed on the first waterproof plate for communicating with opposite sides of the first waterproof plate;
[0010] The ventilation component further includes a second ventilation hole distributed on the second waterproof plate for communicating with opposite sides of the second waterproof plate. The diameter of one side of the second ventilation hole is the same as that of one side of the first ventilation hole, and one end of the second ventilation hole is communicated with one end of the first ventilation hole.
[0011] Further, the first ventilation hole is inclinedly distributed, and the highest point of the first ventilation hole facing the outside of the cabinet is lower than the lowest point of the first ventilation hole facing the inside of the cabinet.
[0012] Further, a liquid level sensor is installed at the bottom of the cabinet; a rain drop induction sensor is installed at the top of the cabinet, and both the liquid level sensor and the rain drop induction sensor are communicatively connected to the control system of the cabinet.
[0013] Further, the ventilation channel includes two groups of symmetrically arranged ventilation openings opened on the side wall of the cabinet.

[0017] The bottom of the driving component is connected to the side wall of the positioning frame, and the top of the driving component is connected to the side wall of the second waterproof plate.
[0018] Further, a mounting bottom plate is installed in the cabinet, and there is a gap between the bottom plate and the bottom of the cabinet, so that a closed cavity is formed at the bottom of the cabinet. An air vent valve is arranged on the side wall of the cavity, and a dehumidification component is installed in the cavity. The input end and the output end of the dehumidification component are both communicated above the bottom plate for dehumidifying the inside of the cabinet.
[0019] Compared with the prior art, the intelligent low-voltage switch cabinet has the following beneficial effects:
[0020] 1. The utility model solves the problem that when there is a lot of rain, the rainwater accumulation is very easy to overflow the waterproof bottom plate and enter the equipment through the heat dissipation holes, thus affecting the normal operation of the equipment.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0029] Such as Figures 1-5As shown in the figure, the utility model provides a technical solution: an intelligent low-voltage switch cabinet, which includes a cabinet body 1. Ventilation channels are provided on two opposite side walls of the cabinet body 1, and a waterproof mechanism is arranged in the ventilation channels to prevent rainwater from entering. The waterproof mechanism includes a first waterproof plate 6, which is arranged in the ventilation channel. A second waterproof plate 7 with the function of sliding up and down is arranged on one side of the first waterproof plate 6. The second waterproof plate 7 and the first waterproof plate 6 are communicated through a number of ventilation components. The number of ventilation components is divided into multiple rows and distributed from top to bottom in sequence, dividing the surfaces of the first waterproof plate 6 and the second waterproof plate 7 into multiple ventilation areas and sealing areas. The ventilation areas and the sealing areas are staggered. The width of the ventilation area is smaller than the width of the sealing area between two adjacent ventilation areas, so that the second waterproof plate 7 uses its own sealing area to seal the ventilation area on the first waterproof plate 6, playing a role in closing the ventilation components. The waterproof mechanism also includes a detection component for detecting the moving distance of the second waterproof plate 7.
[0030] During use, the detection component is an infrared laser distance sensor, and the sensor is communicatively connected to the control system in the cabinet body 1 for collecting data on the moving distance of the second waterproof plate 7. The first waterproof plate 6 and the second waterproof plate 7 form ventilation areas and sealing areas under the opening of a number of ventilation components, and the first waterproof plate 6 and the second waterproof plate 7 are in close contact with each other. When the external rainfall is large, the second waterproof plate 7 is controlled to move upward, so that the sealing area on the second waterproof plate 7 moves upward, and the ventilation areas on the first waterproof plate 6 and the second waterproof plate 7 are staggered, thereby sealing the ventilation areas on the first waterproof plate 6 and the second waterproof plate 7 and completely closing the ventilation channel to prevent rainwater from entering. When the rainfall is small, by controlling the second waterproof plate 7 to move upward, the second waterproof plate 7 moves upward, making the sealing area of the second waterproof plate 7 rise higher than the bottom edge part of the ventilation area on the first waterproof plate 6, forming a shielding effect on one side of the first waterproof plate 6 with the second waterproof plate 7, reducing the effective size of the ventilation channel and preventing rainwater from flowing into the interior of the cabinet body 1.
[0031] The ventilation component includes a first ventilation hole 8 which is distributed on the first waterproof plate 6 and is used to connect the two opposite sides of the first waterproof plate 6; the ventilation component further includes a second ventilation hole 9 which is distributed on the second waterproof plate 7 and is used to connect the two opposite sides of the second waterproof plate 7. The diameter of one side of the second ventilation hole 9 is the same as that of one side of the first ventilation hole 8, and one end of the second ventilation hole 9 is connected to one end of the first ventilation hole 8; during use, the shapes of the first ventilation hole 8 and the second ventilation hole 9 can be circular, square, etc., and the shapes and sizes of the corresponding sides of the first ventilation hole 8 and the second ventilation hole 9 are the same; the first ventilation hole 8 is inclinedly distributed, and the highest point of the first ventilation hole 8 on the side facing the outside of the cabinet 1 is lower than the lowest point of the first ventilation hole 8 on the side facing the inside of the cabinet 1; during use, the inclined first ventilation hole 8 is used to prevent the inclined rainwater from pouring into the second through hole through the first ventilation hole 8, further achieving the effect of rain prevention.
[0032] A liquid level sensor is installed at the bottom of the cabinet 1 for detecting the height of the accumulated water level. The liquid level sensor can adopt a capacitive sensor or an ultrasonic sensor; a rain drop induction sensor is installed at the top of the cabinet 1 for detecting whether it is raining outside the cabinet 1. The rain drop induction sensor can also adopt a microwave radar sensor. Both the liquid level sensor and the rain drop induction sensor are communicatively connected to the control system of the cabinet 1.
[0033] During use, first, the rain drop induction sensor is used to collect information on whether it is raining, and then the liquid level sensor is used to detect the height of the accumulated water level below the cabinet 1, so that when phenomena such as the rapid rise of the accumulated water occur within a certain period of time, the control system of the cabinet 1 issues an intelligent instruction to make the second waterproof plate 7 move upward to close or narrow the ventilation channel to prevent rainwater from entering.
[0034] The ventilation channel includes two groups of symmetrically arranged ventilation openings which are opened on the side wall of the cabinet 1. Positioning frames 13 are detachably installed in the ventilation openings, and the inner side of the positioning frame 13 is detachably installed with the first waterproof plate 6; a fan 10 is installed on one side of one group of positioning frames 13, and the fan 10 is located inside the cabinet 1; a humidity sensor 11 is installed on the inner wall of the cabinet 1, and the humidity sensor 11 is communicatively connected to the control system of the cabinet 1.
[0035] During use, a dust-proof net 17 is detachably installed on one side of the positioning frame 13 outside the cabinet body 1, which has a dust-proof effect on the flowing air. There are four ventilation openings. The first opening 2 and the second opening 3 are symmetrically distributed, and the third opening 4 and the fourth opening 5 are symmetrically distributed. The first opening 2 and the second opening 3 are located below the third opening 4 and the fourth opening 5, and fans 10 are provided at the first opening 2 and the second opening 3 to introduce external air into the cabinet body 1. There are four groups of humidity sensors 11, which divide the interior of the cabinet body 1 into four areas and collect temperature data in the four areas. The four areas are the first area near the first opening 2, the second area near the second opening 3, the third area near the third opening 4, and the fourth area at the fourth opening 5. When it does not rain, when the humidity in the first area or the second area reaches the threshold, the second waterproof plate 7 is driven to move downward, so that the ventilation component is connected, and the ventilation volume in the ventilation opening reaches the maximum, improving the air interaction between the interior and the exterior of the cabinet body 1 and removing the moisture inside the cabinet body 1. Further, when the humidity in the third area is relatively high, first adjust the ventilation volume of the first opening 2 and the second opening 3 to the maximum, and then appropriately drive the second waterproof plate 7 at the fourth area to move upward, reducing the air outlet volume at the fourth opening 5, so that most of the air is discharged through the third opening 4 in the third area, thereby dehumidifying the third area. When the humidity in the fourth area is relatively high, it is the opposite of the third area, guiding the air to be discharged in the fourth area, realizing ventilation and dehumidification inside the cabinet body 1.
[0036] Driving components 12 are installed on both opposite sides of the second waterproof plate 7 for driving the second waterproof plate 7 to move. The bottom of the driving component 12 is connected to the side wall of the positioning frame 13, and the top of the driving component 12 is connected to the side wall of the second waterproof plate 7. During use, the driving component 12 can adopt an electric hydraulic push rod to drive the second waterproof plate 7 to move up and down, adjusting the relative position between the first waterproof plate 6 and the second waterproof plate 7. A sliding groove is provided on the positioning frame 13, and the two opposite side edges of the second waterproof plate 7 are slidably connected to the sliding groove, improving the stability of the up and down sliding of the second waterproof plate 7.
[0037] A bottom plate 14 is installed inside the cabinet body 1. There is a gap between the bottom plate 14 and the bottom of the cabinet body 1, so that a closed cavity is formed at the bottom of the cabinet body 1. An air vent valve 15 is provided on the side wall of the cavity. A dehumidification component is installed in the cavity. Both the input end and the output end of the dehumidification component communicate with the upper part of the bottom plate 14, and are used for dehumidifying the inside of the cabinet body 1. When in use, the dehumidification component can adopt a condensation dryer. When it is detected that the humidity exceeds the threshold in all four regions in the rainy or non-rainy state, the air inside the cabinet body 1 is pumped into the device through the condensation dryer, and after drying treatment, it is discharged into the cabinet body 1 to play a role in drying the air. At the same time, the air vent valve 15 can adopt a solenoid valve, which is communicatively connected to the control system of the cabinet body 1. When it rains, the air vent valve 15 is controlled to close to prevent external rainwater from entering, while the side wall of the cavity and the outside of the cabinet body 1 exchange heat to achieve a heat dissipation effect.
[0038] On the side where the first waterproof plate 6 is in contact with the second waterproof plate 7, a sealing strip 16 is provided. The sealing strip 16 is in contact with the second waterproof plate 7. There are several sealing strips 16, and a sealing strip 16 is provided on both the upper and lower sides of the first ventilation hole 8 to improve the sealing effect between the first waterproof plate 6 and the second waterproof plate 7. When in use, the device first detects whether it is raining through the corresponding sensor. In the non-rainy state, the inside of the cabinet body 1 is divided into multiple regions by the internal humidity sensor 11 for intelligent ventilation and dehumidification of the inside of the cabinet body 1. Secondly, when the rainfall is small, the ventilation volume is appropriately reduced, and the ventilation channels communicating with the outside are blocked to prevent rainwater from entering and also reduce the entry of external humidity. At the same time, the internal drying equipment is controlled to dry. Then, when the rainfall is large, the ventilation channels are closed, and only the internal drying equipment is used for drying, so as to seal the internal water ingress and strengthen the waterproof effect.
