Description

Technical Field

[0001] The utility model relates to the field of distribution boxes, in particular to a distribution box for electrical engineering. Background Art

[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.

[0003] However, the box of the outdoor distribution box is usually made of metal, which has a small specific heat capacity and is easy to absorb heat. In hot weather, the temperature of the side wall of the box is too high, which in turn causes the temperature inside the box to rise, affecting the operation of electrical equipment. Therefore, those skilled in the art provide a distribution box for electrical engineering to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a distribution box for electrical engineering, including a distribution box, three sides of the side of the distribution box are mounting plates, the other side of the side of the distribution box is a box door, the mounting plate is fixedly connected to a connecting cover, the upper and lower parts of the mounting plate are respectively connected to a water inlet pipe and a drain pipe, and a cavity is provided between the mounting plate and the connecting cover.

[0005] Preferably: the mounting plate is plugged with an external thread, and the external thread is threadably connected to the distribution box.

[0006] Preferably, the box door is equipped with a door lock, and a plurality of ventilation holes are provided at the lower part of the box door.

[0007] Preferably: the mounting plate is provided with a groove, a sealing strip is provided in the groove, and the connecting cover is inserted into the groove.

[0008] Preferably: a plurality of side wings are fixedly connected to the edge of the connecting cover, the side wings are interspersed with internal bolts, and the internal bolts are threadedly connected to the mounting plate.

[0009] Preferably: the water inlet pipe and the drain pipe are both equipped with covers.

[0010] Technical effects and advantages of the utility model:

[0011] 1. There is water or coolant inside the three side walls of the distribution box. When the outdoor temperature is too high, the specific heat capacity of water or coolant is greater than that of metal, so that water or coolant can absorb a lot of heat, which prevents the temperature of the outer wall of the distribution box from rising due to sunlight, and thus prevents the temperature inside the distribution box from rising due to the influence of the side walls, ensuring that the temperature inside the distribution box is appropriate, so as to be suitable for the normal operation of electrical equipment;

[0012] 2. A sealing strip is provided at the connection between the mounting plate and the connection cover to form a closed space in the cavity to prevent liquid from leaking from the gap. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0022] See also Figures 1 to 4 In this embodiment, a distribution box for electrical engineering is provided, including a distribution box 1, three sides of the side of the distribution box 1 are mounting plates 2, the other side of the side of the distribution box 1 is a box door 7, the mounting plate 2 is plugged with an external thread 3, the external thread 3 is threadedly connected to the distribution box 1, the box door 7 is installed with a door lock 9, and a plurality of ventilation holes 8 are opened at the bottom of the box door 7;

[0023] The mounting plate 3 is fixedly connected with a connecting cover 10, the mounting plate 3 is provided with a groove, a sealing strip 11 is provided in the groove, the connecting cover 10 is inserted into the groove, a plurality of side wings 12 are fixedly connected to the edge of the connecting cover 10, the side wings 12 are inserted with internal bolts 13, the internal bolts 13 are threadedly connected to the mounting plate 2, the upper and lower parts of the mounting plate 2 are respectively connected with a water inlet pipe 4 and a drain pipe 5, the water inlet pipe 4 and the drain pipe 5 are both installed with sealing covers, and a cavity 14 is provided between the mounting plate 2 and the connecting cover 10.

[0024] The working principle of the utility model is:
