Ground-embedded waterproof optical cable cross-connecting box

Abstract

The invention discloses a ground-embedded waterproof optical cable cross-connecting box which comprises a housing, a middle layer, a waterproof layer and a screw rod. The bottom of the housing is fixed to the middle layer. The middle layer is placed on the waterproof layer. The middle layer is connected with the screw rod. The bottom of the screw rod is rotatably connected with a fixed base through a bearing. The upper end of the screw rod is connected with a servo motor. A box door is slidably arranged on one sidewall of the housing. The chute on the housing is internally provided with a sealing gasket. An air suction pump is mounted in the middle layer. An air suction nozzle and an air discharging nozzle of the air suction pump are respectively connected with a flexible pipe. The two flexible pipes are grounded and are connected with a filtering pipe. The waterproof layer is internally provided with a water pump and a water level switch. According to the ground-embedded waterproof optical cable cross-connecting box, no high requirement for sealing performance of the device is realized in operation, and therefore production difficulty of a device structure is reduced and a good waterproof and moistureproof effect is realized. Furthermore infestation by insects and mice does not easily occur in a long-time use process. Furthermore relatively long effective use period of the components is realized, and maintenance frequency is reduced.

Description

technical field [0001] The invention belongs to the technical field of optical communication equipment, and in particular relates to an underground waterproof optical cable transfer box. Background technique [0002] The optical cable transfer box is an interface device at the junction of the backbone optical cable and the distribution optical cable in the optical cable access network. After the optical cable is connected to the optical cable transfer box, it is fixed, terminated, and distributed. With the continuous growth of information transmission volume and broadband service demand and the demand for fiber-to-the-home construction, the laying area of ​​optical fiber communication lines is becoming more and more extensive, which directly leads to the handover of optical fiber connection and positioning. The box equipment is used in a large amount and has a wide range of applications. [0003] The buried optical cable transfer box can save a lot of urban space. When addi...

Problems solved by technology

[0003] The buried optical cable transfer box can save a lot of urban space. When adding or expanding the volume of the transfer box, it is not necessary to change the buildings or greening of the nearby cities. , due to underground moisture, it is necessary to do a good job of sealing and moisture-proofing the buried optical cable transfer box, but the movable sealing structure such as the sealing door will be not tightly sealed after long-term use, which will lead to accelerated corrosion of the internal components of the transfer box. And it is easy to be infested by insects and rats. When a complete sealing structure is adopted, the gaps at the joints of the various parts of the transfer box are completely sealed by welding or other methods. However, this structure is not conducive to the later expansion and maintenance of the transfer box. At the same time, the traditional When the buried optical cable transfer box is buried underground, it is inconvenient to check and maintain. In order to provide a buried waterproof and moisture-proof optical cable transfer box that is easy to install and maintain, the present invention provides the following technical solutions
