The mouth that pumps up water, exhaust port and pressure instruction interface, the exhaust port outside are equipped with go back at the top of described device lid It is equipped with exhaust apparatus, is equipped with pressure-indication means on the outside of the pressure instruction interface.

The recharge mouth of a river and cable interface are symmetrical on the device housing.

The water fender is curved panel or V-type panel, water fender top and bottom end respectively with described device inner walls It is connected and fixed, is opening between water fender two sides and described device inner walls.

Mouthful outer openings of pumping up water for described time raise piping connection with returning, and return to raise pipeline and be equipped with back and raise switching valve body.

Raise the blowoff line for being additionally provided with and communicating therewith on pipeline for described time, and blowoff line is equipped with scum cock valve body.

Recharge mouth of a river outer openings and recharge piping connection, and recharge pipeline is equipped with recharge switching valve body.

The beneficial effects of the utility model are: it is reasonable in design, each structure is respectively assembled at device housing and device On lid, keep each device assembly space sufficient, later maintenance working space is sufficient, and by the setting of water fender, avoids Recharge water washes away cable, well casing inner wall and device inner wall, improves service using life.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is the system attachment structure schematic diagram of the utility model.

In figure: 1 time mouth that pumps up water, 2 water fenders, the 3 recharge mouths of a river, 4 cable interfaces, 5 cable blind plates, 6 exhaust ports, 7 pressure Instruction interface, raises pipeline for 10 times, 11 blowoff lines, 12 scum cock valve bodies, raises switch 13 times 8 exhaust blind plate, 9 recharge pipelines Valve body, 14 recharge switching valve bodies, 15 exhaust apparatus, 16 pressure-indication means, 17 device lids, 18 device housings.

Specific embodiment

The embodiments of the present invention is illustrated by particular specific embodiment below, those skilled in the art can be by this Content disclosed by specification understands other advantages and effect of the utility model easily.

With reference to the accompanying drawings shown in 1,2: a kind of underground heat well head waterproof flushing device, including device housing 18 and device lid 17, dress Setting shell 18 is the shell that a section is rectangle structure, and the open outer side at 18 top of device housing is fixed equipped with being connected thereto Described device lid 17, in which:

18 bottom end of described device shell is fixed on well casing top, and 3 He of the recharge mouth of a river is respectively equipped on 18 side wall of device housing Cable interface 4, the recharge mouth of a river 3 and cable interface 4 are symmetrical, and the recharge mouth of a river 3 and cable interface 4 shift on device lid 17 Machine-shaping on to device housing 18 greatly reduces the component count on device lid 17, sets inside described device shell 18 There is a water fender 2 being correspondingly arranged with end opening in the recharge mouth of a river 3, water fender 2 is V-type panel, 2 top of water fender and bottom End is connected and fixed with 18 inner wall of described device shell respectively, is opening between 18 inner wall of 2 two sides of water fender and described device shell, So that recharge water contacts after entering device housing 18 with water fender 2, and fallen into well casing at both-side opening, avoids recharge water Cable, well casing inner wall and device inner wall are washed away；

Above-mentioned cable interface 4 uses flange-interface, and cable blind plate 5, cable blind plate 5 has also been bolted in its outside Middle part processes the through-hole for wearing payout, ensures the sealing effect of cable interface 4；
