Abstract
The utility model relates to a waterproof junction box, comprising an upper shell, a transparent observation window which is sealed and embedded in the upper shell, a ventilating port which is arranged under the observation window in the upper shell, and a water incoming detection apparatus which is installed in the upper shell and above the ventilating port. If the junction box loses sealing property and water or moisture invades the junction box, the detection apparatus can detect and send warning information, a maintainer can observe the state of the water incoming detection apparatus timely through the observation window to timely know that whether water enters the junction box or not, and if waterproof performance fails, replacement and maintenance can be carried out early, and thus power utilization safety under mines is ensured.
Description
Technical field
The utility model relates to a kind of electric product, is specifically related to a kind of terminal box.
Background technology
As everyone knows, mining terminal box not only requires it to have good explosion-proof performance, also requires it to have favorable waterproof property.Air humidity in going down into a mine in particular is big, and the water resistance of butted line box proposes higher requirement more.Owing to when terminal box discharges water the performance timeliness after, can cause its interior metal corrosion, exist open circuit, potential safety hazard such as short circuit, so the sealing of terminal box whether qualified needs are checked at any time, singly existing terminal box can not learn but whether its sealing property good.
Summary of the invention
The utility model provides a kind of waterproof junction box that can learn its sealing at any time in order to overcome the deficiency of above technology.
The technical scheme that its technical problem that overcomes the utility model adopts is:
This waterproof junction box comprises upper shell, also comprises the transparent observation window of closed set on upper shell, and the below that described upper shell is equipped with observation window is provided with ventilation mouth, in the housing of described ventilation mouth top into water checkout gear is installed.
Above-mentioned water inlet checkout gear is a water sensitive label.
Above-mentioned observation window adopts polymethyl methacrylate to make.
The beneficial effects of the utility model are: if the sealing property timeliness of terminal box water inlet or enter steam after, checkout gear can detect learns and sends information warning, the maintainer can in time observe the state of water inlet checkout gear by the perspective window, learn in time whether this terminal box intakes, as the repair and replacement early of waterproof timeliness, guarantee Electrical Safety under the ore deposit.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 be among Fig. 1 A-A to cross-sectional view;
Among the figure, 1. upper shell 2. is had an X-rayed windows 3. water sensitive labels 4. ventilation mouths
Embodiment
Be described further below in conjunction with accompanying drawing 1,2 pairs of the utility model of accompanying drawing.
This waterproof junction box comprises upper shell 1, also comprises the transparent observation window 2 of closed set on upper shell 1, and the below that described upper shell 1 is equipped with observation window 2 is provided with ventilation mouth 4, in the housing 1 of described ventilation mouth 4 tops into water checkout gear is installed.If the sealing property timeliness of terminal box water inlet or enter steam after, checkout gear can detect learns and sends information warning, the maintainer can in time observe the state of water inlet checkout gear by perspective window 2, learn in time whether this terminal box intakes, as the repair and replacement early of waterproof timeliness, guarantee Electrical Safety under the ore deposit.
Above-mentioned water inlet checkout gear is a water sensitive label 3.If after the water inlet, steam can contact water sensitive label 3 variable colors by ventilation mouth 4 with water sensitive label 3 in the water terminal box.If the maintainer observes by perspective window 2 and promptly knows terminal box its sealing property timeliness of intaking after water sensitive label 3 variable colors, be replaceable maintenance this moment.
Above-mentioned observation window 2 adopts polymethyl methacrylate to make.Polymethyl methacrylate has fabulous light transmission, can see through the sunlight more than 92%, and ultraviolet ray reaches 73.5%; Mechanical strength is higher, and certain heat-resisting cold resistance is arranged, and corrosion-resistant, insulation property are good, and dimensionally stable is easy to moulding.Be processed into the situation that perspective window 2 can conveniently be observed water sensitive label, make simply with low cost.
Claims (3)
1. waterproof junction box, comprise upper shell (1), it is characterized in that: also comprise the transparent observation window (2) of closed set on upper shell (1), the below that described upper shell (1) is equipped with observation window (2) is provided with ventilation mouth (4), in the upper shell (1) of described ventilation mouth (4) top into water checkout gear is installed.
2. waterproof junction box according to claim 1 is characterized in that: described water inlet checkout gear is water sensitive label (3).
3. waterproof junction box according to claim 1 and 2 is characterized in that: described observation window (2) adopts polymethyl methacrylate to make.
