Most of drainage wells are low-point position settings of a pipeline system, the drainage wells are deeper, personnel are inconvenient to go up and down, a closed space in an inspection well is easy to poison harmful gas once ventilation is insufficient, so that choking accidents are caused, casualties caused by well operation account for more than 80% of casualties of a heating pipeline, and therefore underground operation seriously threatens the life safety of workers. In order to improve the safety of the operation of the drainage well, a main and auxiliary well structure is generally adopted, so that the drainage well has large occupied area and high manufacturing cost, and the waterproof and pipeline corrosion resistance in the well room are difficult problems, and the laying of other pipelines can be influenced under a relatively tense municipal road. An effective solution to the above problems is urgently needed.

In order to achieve the above purpose, the technical scheme adopted by the utility model is that the heat supply direct-buried pipeline water draining and discharging device comprises a heat distribution pipeline, a well chamber is arranged above the lowest point of the heat distribution pipeline, a well lid is arranged at the top of the well chamber, a water draining pipe is connected to the bottom of the heat distribution pipeline, the water draining pipe extends upwards into the well chamber, a first valve and a first flange plug are arranged at the end part of the water draining pipe, a cleaning pipe is connected to the top of the heat distribution pipeline, the cleaning pipe extends upwards into the well chamber, a second valve and a second flange plug are arranged at the end part of the cleaning pipe, and the first valve, the first flange plug, the second valve and the second flange plug are all positioned in the well chamber.

Preferably, the connection position of the cleaning pipe and the heating power pipeline is positioned right above the connection position of the drain pipe and the heating power pipeline.

Preferably, the well lid is flush with the ground, and the number of well lids is used for setting according to the occupation area and ventilation requirement of the well room.

Preferably, the water drain pipe is used for draining water, and when draining water, the first flange is opened for blocking, the first valve is opened for draining water by means of medium pressure of the heating power pipeline in the initial stage, and when the pressure is insufficient, the external water pump is connected for pressurizing and draining water in the heating power pipeline.

Preferably, the cleaning pipe is used for cleaning impurities in the heating power pipeline, and when the impurities block the water outlet, the second valve and the second flange are opened for blocking, and the impurities are cleaned in a mechanical or hydraulic mode.

Compared with the prior art, the utility model has the following technical effects: the utility model can thoroughly drain the water in the pipeline and clean the impurities in the pipeline, the drain well is shallow buried, the personnel operation is easy, the safety is high, the occupation of the well chamber is reduced, the investment is low, and the influence on other pipelines of municipal roads is small. The novel thermal water draining and discharging device has the advantages of high water draining speed, capability of thoroughly emptying the pipeline, simplicity in installation and convenience in operation, investment saving and high safety.
