Description

Geothermal wellhead cable waterproof device

Technical Field

The utility model belongs to geothermol power well head device watertight fittings, the mainly used geothermal water pressurization recharge and malleation well head cable pass through a kind of geothermal well head cable watertight fittings of waterproof use in the pit.

Background

Geothermal energy heating projects are more and more widely developed, geothermal water is used as a heating source, and the geothermal energy heating project has the advantages of economy, environmental protection and energy conservation. According to the national management policy of mineral resources, tail water after geothermal water conservancy is used up needs to be recharged to the corresponding water taking stratum, recharging adopts multiple modes, pressurization recharging is taken as the main mode, a geothermal well head device is a connector of a geothermal well, a ground pipeline and a power distribution facility after the geothermal well drilling is completed, when water pressure in the geothermal well is positive pressure, all connectors of the well head device need to be sealed and pressure-resistant, particularly in the well head device in a pressurization recharging system, the pressure-resistant pressure is up to 1.6MPa, and the connectors and the sealing of the connectors of the well head device need to adapt to corresponding high pressure. The cable penetrating port of the general wellhead device adopts a packing type sealing mode similar to that of a submersible pump cable, when the temperature change of the wellhead is large and the pressure is large, the packing easily generates expansion with heat and contraction with cold, the sealing effect cannot be achieved, the wellhead device needs to be detached in secondary maintenance, and the wellhead device is connected with the submersible pump, so that the detaching work is very troublesome. The geothermal well mouth device is a connector of a geothermal well, a ground pipeline and a power distribution facility after the completion of the drilling of the geothermal well, when the water pressure in the geothermal well is positive pressure, all connectors of the geothermal well mouth device need to be sealed and withstand voltage, and particularly in the wellhead device in a pressurizing recharge system, the withstand voltage is up to 1.6MPa.

SUMMERY OF THE UTILITY MODEL

To the problem that the above-mentioned background art expounded, the utility model aims to solve the technical problem that a geothermal well head cable watertight fittings is provided.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a geothermal wellhead cable watertight fittings, includes wellhead cable, internal thread base, connects to silk, retaining member, presss from both sides tight claw, presss from both sides tight rubber circle, wellhead cable passes the internal thread base, the internal thread base is connected to the silk with being connected, it is located between retaining member and the tight rubber circle of clamp to press from both sides tight claw.

In the technical scheme, the clamping rubber ring is connected with a wellhead cable.

The utility model discloses it is sealed to pass the mouth with the well head cable and adopt retaining member locking, the locking cable need not move the wellhead assembly, even the rubber circle uses ageing needs to be changed for a long time, only need pull down the switch board cable head, with the retaining member, clamp jaw and clamp rubber circle are unloaded from the cable, the accessory of renewing again can, the device simple to operate, seal with clamp rubber circle the cable, lock with retaining member and clamp jaw, the locking dynamics is controllable, can protect the cable can not be harmd when waterproof, it is convenient to have the installation and change, and sealed effectual characteristics.
