Abstract

The utility model relates to a gathering pile for underground source, which comprises a concrete pipe pile of a building foundation. The utility model is characterized in that a U-shaped pipe is arranged in the concrete pipe pile, the upper end of the concrete pipe pile is provided with a concrete core filling cap, and the upper end of the U-shaped pipe penetrates out of the concrete core filling cap and is fixed by a fastening piece. The utility model can directly utilize concrete pipe piles popularized by building industry at present to carry out the installation of closed-loop system pipelines in ground source heat pump systems so as to avoid digging many deep holes which are of 20 to 100 meters deep in the ground and to increase the efficiency of construction. The utility model has the advantages of convenient construction and installation, short construction period, low construction cost, etc.; the utility model can be used for closed-loop system pipelines in ground source heat pump systems.

Description

A kind of underground energy resource collecting pile

(1) technical field

The utility model relates to earth-source hot-pump system, refers to the underground heat collecting pile in this system especially.

(2) background technology

Underground heat is the energy that obtains from earth interior, and the earth is a huge energy storage vault, and it can absorb 47% solar energy.Can there be bigger fluctuation in the temperature of earth surface with changes of seasons, and winter, ambient temperature was very low, and summer, ambient temperature was very high.And the subsurface temperature between surface soil layer 1.5-2 rice is annual constant about 10 ℃.

According to the data of world environments protection general administration, geothermal energy resources are the most efficient at present, environmental protection, and a kind of reliable energy that takes up an area of the space is saved in low energy consumption simultaneously again.It studies show that the ground heat-exchange system reduces emission of harmful substances when can reduce energy consumption significantly,, compare the pollution of environment as carbon dioxide and sulfur dioxide, removed the trouble of stacking coal from coal-burning boiler, compare with oil burning boiler, avoided the investment on oil storage tank to take up an area of again.Save operating cost about 75% with traditional comparing with the power consumption air-conditioning.

Earth-source hot-pump system is exactly according to remaining on the principle of these true geothermal energy of zone of constant temperature of 10 ℃ from the underground degree of depth below about 10 meters in the soil of the earth throughout the year, and the geothermal source (also claim ground can or geothermal energy) of utilizing the earth surface shallow-layer is as thermal source (or low-temperature receiver).One cover system designed and that implement can be realized heat supply in winter, can freeze and provide the system of health living water use again summer.

As high temperature heat source, the heat in the ground energy " is got " to come out to transmit in the building of transferring to the need heating in the winter time by source pump; Summer as cold temperature source, by source pump the heat in the building " is got " to come out to transfer in the earth soil, thereby realizes heat supply in winter, summer refrigeration.Earth source heat pump is realized the transfer of low level heat energy to high-order thermal source by input a spot of high-grade energy (as electric energy).In the winter time, earth source heat pump absorbs the underground energy and is used for constructure heating; Summer, process antithesis, heat pump absorbs heat in the building and it return is underground, has so promptly rationally utilized the underground energy, has kept underground heat again.Ground source heat pump technology has made full use of geothermal energy resources, and with the outstanding advantage of its energy-saving and environmental protection and sustainable development, as novel " green air conditioner ", has become the preferred version of cooling/warming system.

Existing earth-source hot-pump system all is the closed loop heat pumping system generally, and it is most widely used.Closed-loop system is to utilize the heat exchanger fluid be embedded in the underground pipeline and ground heat transfer medium (earth rock, underground water) to carry out interchange of heat and the energy that obtains is sent in the heat pump unit.Can be divided into horizontal closed-loop system and vertical closed-loop system according to the closed-loop system pipeline again in underground mode difference.Wherein perpendicular system is extensively adopted by various places always, its main cause is to extract institute's calorific requirement on limited land area to greatest extent, because it is that heat-exchange tube vertically is embedded in the deep hole about underground 20-100 rice that the pipeline of this system is installed, therefore construct bothers very much, and efficiency of construction is low, cost is high, labor operation intensity is big.Also take bigger ground area simultaneously, also improved construction cost simultaneously.

(3) summary of the invention

In order to solve the technical problem that above-mentioned prior art exists, the utility model provides a kind of concrete tubular pile of building foundation that can directly utilize to construct, easy construction, duration weak point, construction cost underground energy resource collecting pile low, not land occupation area.

The technical scheme that adopts is:

A kind of underground energy resource collecting pile of the present utility model, the concrete tubular pile that comprises a building foundation, it is characterized in that being provided with a U type pipe in the concrete tubular pile of described building, the upper end of concrete tubular pile is provided with concrete and fills out core cap, and the upper end of U type pipe passes concrete and fills out core cap.

The concrete tubular pile that the utility model can directly utilize present builing industry to promote carries out the installation of the closed-loop system pipeline in the earth-source hot-pump system, thereby can avoid digging on the ground the deep hole of many 20-100 rice, has improved efficiency of construction greatly.The utlity model has construction install convenience, advantage such as the construction period is short and construction cost is low, can be widely used in the closed-loop system pipeline in the earth-source hot-pump system.

Fig. 1 is the structural representation of a kind of embodiment of the utility model.

(5) specific embodiment

See also Fig. 1, a kind of underground heat of the present utility model is collected stake, the concrete tubular pile 1 that comprises a building foundation, be provided with a U type pipe 2 in the concrete tubular pile 1, U type pipe 2 is formed by connecting by a plurality of pipeline sections, and the upper end pouring of concrete tubular pile 1 has the concrete of burying reinforcing bar 6 underground to fill out core cap 3, and concrete is filled out and is reserved with two through holes 4 on the core cap 3, its technical essential is that U type pipe 2 upper ends pass through hole 4, and fixing with nut 5.The traversing through end of U type pipe 2 outwards is bent into right-angle elbow pipe.The utility model can connect into the closed-loop system pipeline by elbow and tube connector with the exit of a plurality of U type pipes, so that the energy of gathering is sent in the heat pump unit.
