Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.

Examples

The following is further described with reference to specific embodiments, and referring to fig. 1-2, the present embodiment is a water isolation device for underwater cable connection, which includes a tub body 1 for being placed in water, a waterproof joint 2 is installed at the bottom of the tub body 1, a cable extends into the tub body 1 through the waterproof joint 2, and a drainage assembly 3 for draining water accumulated in the tub body 1 is installed in the tub body 1; specifically, when the water-saving device is used, an operator moves the barrel body 1 to the corresponding tail end of the cable, the barrel body 1 is placed in water, water can slowly enter the barrel body 1 from the waterproof connector 2, the operator passes through the tail end of the cable from the waterproof connector 2 and inwards extends to the barrel body 1 to leave a section, then the waterproof connector 2 is screwed, the waterproof connector 2 and the cable are not fed with water into the barrel body 1, the water-draining assembly 3 is started to slowly pull out the water of the barrel body 1 from the outside of the barrel body 1, so that the operator can conduct extension wiring operation on the cable in a water-free environment inside the barrel body 1, and connection between the cable and a junction box is ensured.

Referring to fig. 1, the drainage assembly 3 used in this embodiment includes a micro water pump 31 and a water conduit 32, the micro water pump 31 is disposed outside the tub 1, one end of the water conduit 32 is connected to the micro water pump 31, and the other end of the water conduit 32 extends to the bottom end of the tub 1 to be tightly attached; the penstock 32 is made of a flexible transparent material; specifically, the configurable storage battery supplies power to the micro water pump 31, and because the hole of the waterproof connector 2 is smaller, when the cable passes through the waterproof connector 2, excessive water does not flow into the barrel body 1, and the front end of the drinking water pipe is tightly attached to the bottom of the barrel body 1, so that the water can be fully pumped out.
