Technical Field

The invention relates to the technical field of well construction engineering, in particular to a special well for an underground water source heat pump.

Background

Nowadays, a water source heat pump system can heat in winter due to high efficiency and energy conservation, and gradually replaces an air conditioning system with a function of refrigerating in summer, and particularly, the water source heat pump system has more obvious energy-saving effect and gradually becomes standard configuration of high-density building groups such as homes, schools, hospitals, office buildings and the like. The water source heat pump needs to draw underground water as a basic temperature medium for temperature exchange; because the temperature of the underground water foundation is constant, the heat of the underground water displaced in winter is led into the room for heating; in summer, the cold energy of the replaced underground water is led into the room for refrigeration.

The existing underground water source well generally utilizes a water taking well and a water returning well; after the water in the water taking well is extracted, the cold water or hot water generated after the exchange of the water source heat pump compressor is introduced into the backwater well for recharging or is introduced into a sewer. This can cause water loss, or return water temperature loss, resulting in waste. For example, the groundwater extracted in winter is changed into cold water after heat extraction and flows back to a backwater well or a sewer, so that cold loss is caused; the underground water extracted in summer is changed into hot water after being extracted by cold energy and flows back to a backwater well or a sewer, so that heat loss is caused; moreover, the cost of drilling two wells increases. Therefore, it is particularly necessary to prepare an integrated well which can draw water and return water and can store cold or heat.

Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

As shown in fig. 1, the segment vacuum well of the present embodiment is composed of a well body 1, an internal pipe 2, a conical screw 3, a conical nut 4, and a well lid 5, and is characterized in that: the middle part of the well body 1 is provided with a conical nut 4; the inner pipe 2 is divided into an upper inner pipe 21 and a lower inner pipe 22; the conical screw 3 is fixed in the middle of the lower built-in pipe 22, the conical screw 3 is meshed with the conical nut 4, and the upper built-in pipe 21 is positioned above the conical nut 4 and the conical screw 3; the well lid 5 is assembled at the upper end of the well body 1 in a sealing mode, the upper built-in pipe 21 and the lower built-in pipe 22 lead out of the well lid 5, and the upper built-in pipe 21, the lower built-in pipe 22 and the well lid 5 are processed in a sealing mode. The well body 1 consists of a water seepage pipe 11 and a non-water seepage pipe 12; the upper part and the lower part of the well body 1 are provided with water seepage pipes 11, and the middle part is provided with a non-water seepage pipe 12; the water seepage pipe 11 is densely distributed with water seepage holes, and water can freely pass through the water seepage holes; the non-permeable pipe 12 has a compact structure and water cannot pass through. The inner pipe 2 belongs to a common water guide pipe. The conical screw 3 and the conical nut 4 can be screwed tightly and engaged into a whole.

The lower built-in pipe 22 is arranged in the well body 1 with a conical screw 3 and is tightly screwed with a conical nut 4 preset in the middle of the well body 1; thus, the well body 1 is separated into an upper part and a lower part; the upper space of the well body 1 is communicated with an upper underground water system through an upper water seepage pipe 11, and the lower space of the well body 1 is communicated with a lower underground water system through a lower water seepage pipe 11.

In winter, water is taken by using the upper built-in pipe 21, the temperature of return water is reduced to be cold water after the heat is absorbed by the water source heat pump system, and then the cold water is guided into the space at the lower part of the well body 1 by the lower built-in pipe 22; the water enters the water system at the lower part of the well body 1 through the wall of the water seepage pipe 11, so that the temperature of the water system and soil around the lower part of the well body 1 is reduced, a cold area is formed, the water base temperature of the cold area is low, and the water base is stored for being drawn and utilized in summer, so that the aim of saving more energy is fulfilled.

In summer, the lower built-in pipe 22 is used for taking water, the temperature of return water is raised to be changed into hot water after the cold energy is absorbed by the water source heat pump system, and then the hot water is guided into the upper space of the well body 1 through the upper built-in pipe 21; the water enters the water system at the upper part of the well body 1 through the wall of the water seepage pipe 11, so that the temperature of the water system and soil around the upper part of the well body 1 is increased, a hot zone is formed, the water base temperature of the hot zone is high, the water is ready for being drawn and utilized in winter, and the aim of saving more energy is fulfilled.

Due to the sealing effect of the well cover 5, the overflow phenomenon caused by slow backwater at the upper part of the well body 1 in summer is avoided.
