Abstract

The utility model provides an underwater lamp mounting structure, which comprises a waterproof lamp, an expansion screw, a lamp shade hole, a waterproof wire, a galvanized steel pipe, a sealant, a junction box and a common wire, wherein the waterproof lamp is arranged on the lamp shade hole; the waterproof lamp is placed in the lamp shade hole and is fixed on the wall body from the front side of the wall body by adopting expansion screws; the galvanized steel pipe is pre-embedded in a path through which an electric wire passes in the wall body, one end of the waterproof electric wire is connected with the waterproof lamp, and the other end of the waterproof electric wire is connected with the junction box after penetrating through the galvanized steel pipe; the waterproof wire is sealed at the exposed part of the lampshade hole by adopting sealant to seal the opening of the galvanized steel pipe; the common electric wire and the waterproof electric wire are connected in the junction box; the junction box is higher than the highest water level. The lamp junction box has no water seepage threat and high reliability, and can supply power normally even if more water seepage exists in the lampshade hole; common wires can be adopted behind the junction box, so that the cost of the wires is reduced; the waterproof lamp is taken out, overhauled and replaced without dismounting the wire in water, and the operation is easy.

Description

Underwater lamp mounting structure

Technical Field

The utility model relates to the field of lamp installation, in particular to an underwater lamp installation structure.

Background

In reservoirs and hydropower stations, searchlights are arranged in water for observing foreign matters in water and observing the water quality. At present, waterproof lamps with higher protection level are generally adopted, however, electric leakage and short circuit faults often occur due to the fact that the installation process is not in place, the junction box is prone to water seepage and the like, and moreover, the underwater lamp is difficult to disassemble and maintain, and reliability and safety of the underwater lamp are also affected.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an underwater lamp mounting structure which improves the reliability of an underwater lamp and is convenient to disassemble. The utility model adopts the following technical scheme:

an underwater lamp mounting structure is characterized by comprising a waterproof lamp, an expansion screw, a lamp shade hole, a waterproof wire, a galvanized steel pipe, a sealant, a junction box and a common wire; the lampshade hole is arranged at the height of the wall body below the corresponding water surface, and the waterproof lamp is placed in the lampshade hole and is fixed on the wall body from the front side of the wall body by adopting an expansion screw; the galvanized steel pipe is pre-embedded in a path through which an electric wire passes in the wall body, one end of the waterproof electric wire is connected with the waterproof lamp, and the other end of the waterproof electric wire is connected with the junction box after penetrating through the galvanized steel pipe; the waterproof wire is sealed at the exposed part of the lampshade hole by adopting sealant to seal the opening of the galvanized steel pipe; the common electric wire and the waterproof electric wire are connected in the junction box; the junction box is higher than the highest water level.

Furthermore, the head of the waterproof lamp is provided with a flange edge, and the flange edge is pressed on the orifice wall of the lamp shade hole and is fixed on the wall from the front by adopting an expansion screw.

Further, the volume of the cavity of the lampshade hole meets the requirement that the length of the waterproof wire coiled in the lampshade hole can be larger than the installation depth H of the waterproof lamp, and is preferably larger than 1.5 times of the installation depth H of the waterproof lamp; the length of the waterproof wire coiled in the lampshade hole is larger than the installation depth H of the waterproof lamp, and preferably is larger than 1.5 times of the installation depth H of the waterproof lamp.

By adopting the technical scheme of the utility model, the junction box of the lamp has no water seepage threat and high reliability, and can normally supply power even if more water seepage exists in the holes of the lampshade; common wires can be adopted behind the junction box, so that the cost of the wires is reduced; the waterproof lamp is taken out, overhauled and replaced without dismounting the wire in water, and the operation is easy.
