Description
The present invention relates to an end protection cover of an underground heat exchanger, and more particularly, it is possible to effectively protect the end of the underground heat exchanger during the shredding removal work of the upper concrete, the underground which can be installed and dismantled very simply and quickly A protective cover for an end portion of a heat exchanger.
Recent economic growth in China and India has led to a surge in demand for petroleum and an unstable political situation in oil-producing countries, leading to more interest in new energy sources to replace fossil fuels than ever before.
As a new alternative energy source, researches on solar heat, wind power, and geothermal heat are being conducted. These energy sources have the advantage of obtaining energy with little influence on air pollution and climate change, but have a very low energy density. There is also.
In particular, in order to obtain sufficient energy by using wind and solar heat, it is necessary to secure a large installation area, and due to environmental variability such as uneven wind speed or sunshine, energy production is not constant and costs are considerable for maintenance. There is a limit.
Therefore, there is a high interest in geothermal energy, which can always obtain a constant energy, and relatively low cost for maintenance.
In general, a geothermal air-conditioning apparatus using geothermal energy is an underground heat exchanger for cooling refrigerant and connected to the ground heat exchanger, and a heat pump and a heat pump connected to the underground heat exchanger to circulate the refrigerant and transfer the recovered ground heat to a required place. It is composed of a control unit for controlling the.
As such, in order to use geothermal energy, the installation hole must be drilled into the ground and an underground heat exchanger must be inserted into the ground. Therefore, the initial construction time and cost are high.
In order to solve this drawback, in recent years, a method of constructing an underground heat exchanger with other civil structures has been studied. An example of this is a method of constructing an underground heat exchanger when constructing a slurry wall continuously in the ground using a high density stabilizer.
The sequence of construction of the slurry wall and the heat exchanger is as follows.
First, the excavation part is excavated to form an excavation portion, and the excavation portion is filled with a stabilizer so as not to collapse. After installing the underground heat exchanger and the reinforcing bar at the excavation section, the slurry wall is formed by filling and curing concrete at the excavation section while recovering the stabilizer.
At this time, the upper end concrete of the slurry wall is formed, since the strength is lowered while mixing the impurities such as the stabilizer and the suspended solids, the upper concrete is crushed and removed, and then the concrete is poured again.
However, when the upper concrete is crushed and removed as described above, there is a problem that the end of the underground heat exchanger protruding from the upper concrete is damaged by being impacted by the crusher. If the end of the underground heat exchanger is broken, it must be repaired or rebuilt, which is very serious because it takes a lot of time and money.
In order to solve this problem, the end of the ground heat exchanger was cut to a suitable size by wrapping the end of the underground heat exchanger and temporarily fixing it with a tape or a band to prevent the end of the ground heat exchanger. It takes a lot of time to install and dismantle, not only the fixing of the cushioning material is not robust, but also has the disadvantage of very cumbersome work.
In this way, the direct contact between the end of the underground heat exchanger and the crusher can be blocked, but due to the vibration or shock transmitted from the crusher, the pair of heat exchanger tubes at the end of the underground heat exchanger come into contact with and impact each other. There is a limit that damage cannot be completely prevented.
In order to solve the problems as described above, the present invention can mitigate the shock transmitted to the heat exchanger tube while keeping the pair of heat exchanger tubes at the end of the underground heat exchanger end from being damaged by impacting each other, the underground heat exchanger It is an object of the present invention to provide an end protection cover of an underground heat exchanger that can be fixed to an end and can be easily adjusted in its installation position.
In order to solve the problems as described above, the end protection cover of the underground heat exchanger according to the present invention is temporarily installed at the end of the underground heat exchanger, the end of the underground heat exchanger during the shredding removal operation of the upper concrete mixed with impurities A cover that protects from damage, the cover is provided between the pair of heat exchanger tube of the underground heat exchanger end to maintain the pair of heat exchanger tube spaced apart from each other; It is made of a material having elasticity and provided in the shape of a sleeve formed with an opening in the longitudinal direction, it is delivered to the pair of heat exchanger tube wrapped around the pair of heat exchanger tube and the spacer inserted to extend the opening Shock absorbers; And a fixing part for fixing the buffer body so as not to be separated while surrounding the pair of heat exchange tubes and the spacer.
The spacer may include a pair of grooves into which the pair of heat exchange tubes are inserted, respectively, and may be made of an elastic material to mitigate an impact.
The fixing part may include a cover body provided in a sleeve shape having an opening formed along a longitudinal direction corresponding to the shock absorber and fixed to an outer circumferential surface of the shock absorber, and the opening may expand as the opening is expanded; And fastening members installed on both sides of the opening of the cover body to fix the opening so as not to expand so that the cover body can be fixed in a state of pressing the outer circumferential surface of the buffer body.
The fastening member may include: a first fastening member rotatably installed at one side of the opening of the cover body and having a predetermined locking hole; And a second fastening member provided at the other side of the opening of the cover body and having a locking protrusion inserted into and fixed to the locking hole.
The cover body, the support pillar is fixed in the longitudinal direction to the buffer to support the buffer not to bend along the longitudinal direction; And a pair of casings formed of an elastic material so as to be provided at both ends of the support pillar in the width direction, respectively, to form the opening between the ends thereof, and to be bent with respect to the support pillar.
According to the cover for protecting the end of the underground heat exchanger of the present invention, a pair of heat exchanger tube of the underground heat exchanger end is delivered to the heat exchanger tube wrapped around the spacer and the end of the underground heat exchanger to be spaced apart at regular intervals so as not to damage each other. A shock absorber is provided to absorb and mitigate the impact that can be effectively protected at the end of the underground heat exchanger during the shredding removal of the upper concrete.
In addition, the buffer body is formed with an expandable opening for easily inserting a pair of heat exchange tubes, and has an opening corresponding to the opening for simply fixing or releasing the buffer to the end of the underground heat exchanger. By providing a fixing portion formed in a shape surrounding the buffer body, the fixing portion can be installed and dismantled very easily and quickly at the end of the underground heat exchanger.
In addition, since the fixing part includes a cover body including a support column for supporting the buffer body not to bend, the mounting position can be stably adjusted by holding and transporting the cover body in a state of being installed at the end of the underground heat exchanger. Its installation is easier.
