Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to an outdoor operation distribution box. Background Art

[0002] With the development of power technology and the increase in electricity demand, the demand for the use of outdoor distribution boxes is also gradually increasing. Outdoor distribution boxes are distribution boxes installed outdoors to control the transmission of electricity. In traditional technology, in order to realize the output and input of electricity, it is necessary to directly open wire holes on the distribution box to allow the power lines to pass through the distribution box. However, rainwater can easily penetrate into the distribution box along the wires, causing the internal circuit of the distribution box to be affected by rainwater and malfunction. There is a problem of poor waterproof effect of the distribution box, and most distribution boxes have holes reserved during production. The number of holes is often greater than the usage demand. Water is also easy to enter the empty holes when it rains; and in the event of a malfunction, short circuit or even fire, the operator needs to open the front door to see the situation inside the distribution box, which poses certain safety risks.

[0025] See also Figure 1-Figure 3 As shown, the line-in device 7 includes several wire tubes 7-1, which are nested and movably installed. Several sealing rings 7-3 are provided on the inner side of each wire tube 7-1, and a blocking column 7-2 is movably inserted in the innermost wire tube 7-1; the end of the line-in device 7 located on the outer side of the box body 1 is installed with a downward tilt.

[0026] As an optimization scheme of the utility model, several wire tubes 7-1 of different diameters are provided and can be movably removed. A suitable wire tube 7-1 can be selected according to the thickness of the wire to be installed, and the wire can be installed by pulling out the extra wire tube 7-1 installed inside. The blocking column 7-2 is used to block when the wire is not installed to prevent water vapor from entering. The sealing ring 7-3 can ensure the air tightness of the wire feeder 7, and the wire feeder 7 is installed at an angle, so that water on the wire will automatically flow downward instead of entering the interior of the box 1.

[0027] See also Figure 1-Figure 5As shown, the waterproof ventilation structure includes a side baffle 5 obliquely arranged on the side of the box body 1, and baffles are connected between the two sides of the side baffle 5 and the box body 1, and a ventilation hole 14 is opened on the box body 1 below the installation position of the side baffle 5; the quick-change filter assembly includes a filter screen 10 arranged on the inner side of the side baffle 5, and the side of the filter screen 10 facing the side baffle 5 is provided with a plurality of plugs 11, and a plurality of slots 12 are opened in the side baffle 5, and the plugs 11 are movably arranged in the slots 12, and a plurality of "V"-shaped spring sheets 13 are provided on the box body 1, and the opening of the spring sheet 13 is arranged upward below the filter screen 10.

[0028] As an optimization solution of the utility model, an inclined side baffle 5 is provided, and a vent 14 is provided at an internal position thereof to prevent rainwater from entering, and one side of the filter 10 is fixed by inserting a plug 11 into a slot 12, and the other side presses a spring sheet 13 during installation, and when reaching above the spring sheet 13, the spring sheet 13 can automatically rebound, thereby fixing the filter 10 and facilitating replacement.

[0029] See also Figure 1-Figure 6 As shown, the observation window 3 includes a glass plate 1 3-1 and a glass plate 2 3-2 embedded in the box door 2, a gap is left between the glass plate 1 3-1 and the glass plate 2 3-2, and sealing strips 3-3 are provided around the glass plate 1 3-1 and the glass plate 2 3-2 and at the installation position of the box door 2.

[0030] As an optimization solution of the utility model, double-layer glass is set for observation, and air isolation exists between glass plate 1 3-1 and glass plate 2 3-2, which can reduce the heat transfer between the inside and the outside, thereby preventing fogging caused by temperature difference, and can also provide sound insulation.

[0031] The use process of this utility model:

[0032] First, install the distribution box in place. When it is necessary to install the wire, select the appropriate wire tube 7-1 in the incoming wire device 7 according to the diameter of the wire, and pull out the remaining wire tubes 7-1 and the blocking column 7-2 inside it, and then install the wire. The same operation can be performed to complete the installation of the wire in the outgoing wire device 8. When the outgoing wire device 8 is not needed, all the devices inside it can be installed in the outgoing wire device 8, so as to prevent moisture from entering from the outgoing wire device 8.

[0033] When the filter needs to be replaced, several spring sheets 13 are pressed inward at the same time, and the side of the filter 10 close to the spring sheet 13 loses support and automatically falls down, and then the filter 10 is pulled out, and the plug 11 of the new filter 10 is inserted into the slot 12, and then the other side of the filter 10 is pushed upward, and the filter 10 presses the spring sheet 13. After the filter 10 is pushed into place, the spring sheet 13 automatically rebounds and jams the filter 10;

[0034] When the heat generation is high, a cooling fan may be installed at any vent 14 to enhance air convection;

[0035] When a fault occurs, the operator does not need to open the box door 2, but observes from the observation window 3 first, determines the fault location and risk level, and then decides on the next operation. When opening the door through the insulating handle 9, the insulating handle 9 can also isolate the electricity, thereby ensuring their own safety.

[0036] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
