[0002] The distribution box is an electrical equipment with the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint and environmental protection. By setting cable interfaces and functional modules for collecting power consumption data inside the distribution box, an intelligent distribution cabinet for power consumption information collection is formed. In actual use, the cable interfaces set inside the distribution box are connected to the signal cables for data collection, and different functional modules are used to maintain the normal operation of the distribution box, so as to collect power consumption information.

The intelligent distribution box for collecting electricity information pushes the dehumidification seat into the interior of the distribution box body through the baffle. At this time, the movement of the dehumidification seat drives the filter and the desiccant particles to move until the dehumidification seat is located inside the distribution box body. The movement of the baffle drives the fixed sleeve to the surface of the positioning column, and then the position of the fixed sleeve is fixed by the threaded column, which can achieve the dehumidification effect, prevent the internal components of the distribution box from getting damp, and ensure the service life of the internal components of the distribution box.

[0004] Based on the above, it is found that the distribution box has a relatively simple treatment for moisture in the body and is unable to discharge the moisture in the body as much as possible. When there is a large amount of moisture in the body, the distribution box and the circuit will become damp, which may cause a short circuit in the circuit. Utility Model Content

[0018] Compared with the prior art, the advantages of the utility model are:

[0019] The utility model discloses a safe low-voltage distribution box. Through the arrangement of a blower mechanism and a dehumidification mechanism, the calcium chloride particles in the dehumidification mechanism absorb water molecules in a machine body. The water molecules absorbed by the calcium chloride particles can flow into a shell body through a water filter hole and be discharged from the machine body through a water outlet pipe. When the calcium chloride particles are saturated, a motor starts to drive fan blades to perform a blow process. A heating wire is arranged in front of the fan blades. The wind blown out by the fan blades becomes hot water. While dehumidifying the machine body, the calcium chloride particles are also dried. After the drying process of the calcium chloride particles is completed, the calcium chloride particles can be used again. This solves the problem that the dehumidification process in the distribution box is not in place, which may cause the circuit to be damp and cause a short circuit. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in 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 in 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. Example

[0028] See also Figure 1-6 A safe low-voltage distribution box includes a body 1, a bracket 2, a door panel 3, and a ventilation mechanism 4. The bracket 2 is fixed at the lower end of the body 1, the door panel 3 is installed on the body 1, and ventilation mechanisms 4 are provided on both sides of the body 1. The body 1 includes a back plate 11, electrical components 12, a partition 13, a blower mechanism 14, and a dehumidification mechanism 15. The back plate 11 is fixed in the body 1, and the electrical components 12 are evenly distributed on the back plate 11. The partition 13 is fixed in the body 1, and the blower mechanism 14 is installed on the partition 13. The inner bottom surface of the body 1 is provided with a dehumidification mechanism 15.

[0029] By disposing the dehumidification mechanism 15, a better dehumidification effect can be achieved in the machine body 1, and the wind blown out by the blowing mechanism 14 is hot wind, which can also perform dehumidification.

[0030] In this embodiment, the dehumidification mechanism 15 includes a filter plate 51, a shell 52, a moisture-absorbing paper 53, a placement plate 54, and a water outlet pipe 55. The shell 52 is fixed to the inner bottom surface of the body 1, and the filter plate 51 is fixed on the shell 52. The shell 52 is provided with moisture-absorbing paper 53 in contact with the filter plate 51, and a placement plate 54 is provided under the moisture-absorbing paper 53. The shell 52 is provided with a water outlet pipe 55 that passes through the body 1.

[0031] The filter plate 51 is provided to prevent dust from falling directly onto the moisture-absorbing paper 53 , and calcium chloride particles are placed between the moisture-absorbing paper 53 and the placement plate 54 .

[0032] In this embodiment, the placement plate 54 is in an inverted triangle shape, and a water filtering hole 051 is provided on the placement plate 54 .

[0033] The above-mentioned placement plate 54 is set, and the calcium chloride particles on the placement plate 54 can absorb water molecules in the air. When the calcium chloride particles absorb the water molecules in the air, water droplets will be formed on the placement plate 54, and the water droplets will flow into the shell 52 through the water filter hole 051.

[0034] In this embodiment, the water outlet pipe 55 includes a tube body 61, a circular plate 62, a round rod 63, an arc groove 64, a spring 65, and a fixing part 66. The tube body 61 passes through the body 1 and is fixed to the shell 52. An arc groove 64 is provided in the tube body 61, and a circular plate 62 movable with the tube body 61 is provided on the arc groove 64. A round rod 63 is fixed under the circular plate 62, and a spring 65 is fixed under the round rod 63. The other end of the spring 65 is provided with a fixing part 66 fixed to the tube body 61.

[0035] By setting the above-mentioned water outlet pipe 55, when the water storage in the shell 52 reaches a certain amount, the water pressure will press the circular plate 62, and the circular plate 62 will move downward. When the circular plate 62 moves to the position of the arc groove 64, the water flow can be discharged from the water outlet pipe 55. When the water pressure decreases and is not enough to press the circular plate 62, the spring 65 fixed on the round rod 63 will lift the circular plate 62 again, and close the channel of the water outlet pipe 55 again to prevent moisture on the ground from entering the body 1.

[0036] In this embodiment, the hair dryer mechanism 14 includes a motor 21, fan blades 22, a ring 23, and a heating wire 24. The motor 21 is fixed on the partition 13, the fan blades 22 are fixed on the output shaft of the motor 21, the ring 23 is fixed under the partition 13, and the heating wire 24 is installed on the ring 23.

[0037] By setting the heating wire 24 as mentioned above, when the calcium chloride particles in the shell 52 are saturated, they can no longer absorb the water molecules in the body 1. At this time, when the humidity sensor in the body 1 senses that the humidity in the body 1 is too high, the motor 21 will start, driving the fan blades 22 to rotate and blow air, and a heating wire 24 is provided in front of the fan blades 22. The heating wire 24 converts the wind blown out by the fan blades 22 into hot air, which is more conducive to dehumidification. The calcium chloride particles in the shell 52 can be dried under the drying of the hot air. After the calcium chloride particles are dried, they can be reused to absorb the water molecules in the body 1 again, forming a virtuous circle.

[0038] In this embodiment, the ventilation mechanism 4 includes a ventilation groove 41, an inclined plate 42, a dustproof plate 43, and a water baffle 44. The ventilation groove 41 is provided in the body 1, the inclined plate 42 is fixed in the ventilation groove 41, a dustproof plate 43 is installed on one side of the ventilation groove 41, and a water baffle 44 is fixed on the dustproof plate 43.

[0039] The above-mentioned water retaining plate 44 is set at a 45-degree angle downward to prevent rainwater from entering the ventilation slot 41. Even if some rainwater enters, an inclined plate 42 is fixed in the ventilation slot 41, and the inclined plate 42 is set at a 45-degree angle upward, so that when rainwater flies in, it will be blocked by the inclined plate 42 and slide out along the inclined plate 42.

[0040] Working principle:

[0041] Through the setting of the dehumidification mechanism, the setting of the filter plate 51 is to prevent dust from falling directly on the moisture-absorbing paper 53, and calcium chloride particles are placed between the moisture-absorbing paper 53 and the placement plate 54. The calcium chloride particles can absorb water molecules in the air. When the calcium chloride particles absorb water molecules in the air, water droplets will form on the placement plate 54, and the water droplets will flow into the shell 52 through the water filter hole 051. When the water storage in the shell 52 reaches a certain amount, the water pressure will press the circular plate 62, and the circular plate 62 moves downward. When the circular plate 62 moves to the position of the arc groove 64, the water flow can be discharged from the water outlet pipe 55. When the water pressure decreases and is not enough to press the circular plate 62, the spring 65 fixed on the round rod 63 will re-press the circular plate 62. The plate 62 is lifted up to close the passage of the water outlet pipe 55 again to prevent moisture on the ground from entering the body 1. When the calcium chloride particles in the shell 52 are saturated, they can no longer absorb the water molecules in the body 1. At this time, when the humidity sensor in the body 1 senses that the humidity in the body 1 is too high, the motor 21 will start to drive the fan blades 22 to rotate and blow air. A heating wire 24 is provided in front of the fan blades 22. The heating wire 24 converts the wind blown out by the fan blades 22 into hot air, which is more conducive to dehumidification. The calcium chloride particles in the shell 52 can be dried under the drying of the hot air. After the calcium chloride particles are dried, they can be reused to absorb the water molecules in the body 1 again, forming a virtuous circle.

[0042] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
