Embodiment 1

[0038] A waterproof distribution box, including a box body, such as figure 1 As shown, the box includes a ventilated lower box 1 and a sealed upper box 2 placed on the top of the ventilated lower box 1 .

[0039] The above-mentioned ventilated lower box body 1 and sealed upper box body 2 are shells with one side opening, and the opening sides of the ventilated lower box body 1 and the sealed upper box body 2 are respectively provided with a ventilated box door 3 and a sealed box door. The airtight box door comprises inner door 4 and outer glass door 5 again.

[0040] A first sealing strip 6 is provided between the above-mentioned inner door 4, the outer glass door 5 and the door frame of the sealed upper box body 2, and a second sealing strip is arranged between the above-mentioned ventilated box door 3 and the door frame of the ventilated lower box body 1 7; In addition, in this embodiment, the first sealing strip 6 includes interconnected clamping parts and sealing bubbles 6....

Embodiment 2

[0044] This embodiment is basically the same as Embodiment 1, the difference is:

[0045] The length and width of the above-mentioned water retaining body 8 are respectively greater than the maximum length and maximum width of the box;

[0046] A first temperature sensor and a first humidity sensor are provided inside the sealed upper box 2 , and a second temperature sensor and a second humidity sensor are provided inside the ventilated lower box 1 .

Embodiment 3

[0048] This embodiment is basically the same as Embodiment 1, the difference is:

[0049] In order to further enhance the waterproof performance of the distribution box, a water-absorbing resin layer 14 is provided between the sealed upper box body 2 and the ventilated lower box body 1 in this embodiment.

Abstract

Disclosed in the invention is a waterproof distribution box comprising a box body including a lower ventilation box body and an upper sealing box body. A ventilation box door and a sealing box door are respectively arranged at opening sides of the lower ventilation box body and the upper sealing box body. The sealing box door includes an inner side door and an outer side glass door. First sealing strips are arranged between the inner side door, the outer side glass door and the door frame of the upper sealing box body. A water blocking structure is arranged at the top of the upper sealing box body and contains a water blocking body; at least one horizontal drainage slot is formed in the water blocking body; and a first water blocking plate and a second water blocking plate are arranged at the front end and the rear end of the water blocking body obliquely. Besides, an air inlet fan and an exhaust fan are respectively arranged at the left side wall and the right side wall of the lower ventilation box body. According to the waterproof distribution box, the rainproof and waterproof performances are good; the insulation strength inside the distribution box can be maintained and the short-circuit phenomenon in the distribution box is prevented; the safety factor is high; and the service life of the box is prolonged.

Description

technical field [0001] The invention relates to the field of distribution boxes, in particular to a waterproof distribution box. Background technique [0002] Distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution equipment, can connect with manual or automatic switch during normal operation. Make or break a circuit. [0003] The existing distribution boxes are generally installed outdoors, and their rainproof and waterproof performance is poor, and there are inevitably some gaps on the box body. Such defects further weaken the rainproof and waterproof performance of the distribution box. The internal insulation strength leaves a potential safety hazard. In severe cases, it may cause a short circuit in the circuit in the distribution box, causing a power outage and affecting the normal work and life of t...
