Embodiment Construction

[0008] See figure 1 , the refilling water enters the refilling water pipe 1 at a certain flow rate and speed, and its static pressure energy acts on the inner wall of the static and dynamic pressure energy converter. When the water flows out from the small hole 2 on the radially outer surface, Most of the static pressure energy is converted into the dynamic pressure energy of water, which impacts the gravel 3 around it, and automatically forms a drainage channel. Since the conditions of the position of the static and dynamic pressure energy changer are artificially selected, it is easy to Create drainage channels. Therefore, the recharge water is continuously recharged from the ground back to the ground, and the recharge drainage channel becomes smoother and smoother under the action of the dynamic pressure energy of the recharge water and the washing of the water, and there is no need for deliberate maintenance at all. .

Abstract

The invention relates to a novel structure recharge device and an implementation method, which can guarantee that water after heat exchange with a water source heat pump is permanently, reliably and completely recharged to the underground. The recharge principle of the invention is accurate and mature; the structure of the recharge device is simple; the implementation method is easy; the investment is small; the recharge effect is good. The invention comprises a recharge water pipe and a dynamic and static pressure energy converter which is arranged on the tail of the recharge water pipe. The invention is characterized in that: the recharge dynamic and static pressure energy converter is arranged on the tail of the recharge water pipe and takes the structure of a container; the lower part of the dynamic and static pressure energy converter is a closed structure which is provided with a plurality of water outlet eyelets in the radial direction; the sum total of the section area of the eyelets is smaller than the section area of the recharge water pipe; the upper part of the dynamic and static pressure energy converter takes the structure of an opening which is connected with the tail of the recharge water pipe; and outsides of sections provided with eyelets are covered with filter screens. In a newly-built recharge water project, the novel structure recharge device is descended into a drilled vertical shaft and the dynamic and static pressure energy converter is arranged on a geological stratification position with the best recharge water effect, and then gravels are filled in gaps between the shaft wall and the outside diameter of the dynamic and static pressure energy converter. Materials such as sands or cement mortars and so on are filled in gaps between the recharge water pipe and the shaft wall; in a recharge water project of the prior 'recharge well'.

Description

technical field [0001] The invention belongs to a device for refilling water underground, in particular to a refilling device with a brand-new structure capable of long-term, reliable and economical water refilling underground and an implementation method. It is suitable for any project that recharges the water on the ground back to the ground, especially for the recharge water project of the water source heat pump. Background technique [0002] In the past, the water on the ground was recharged back to the ground, and the recharge well was generally used. The structure of the recharge well is similar to that of the water extraction well. The recharge methods are basically: natural static pressure recharge, vacuum recharge, and pressure recharge. There are disadvantages such as small amount of reinjection water, short service life of reinjection well and high maintenance cost. Contents of the invention [0003] The object of the present invention is to provide a rechargin...
