Detailed description of the invention
In conjunction with accompanying drawing 1 to 3, the utility model is further described:
A kind of ground temperature energy heat exchanger, including the heat exchanger tube passed in wellhole 10, heat exchanger tube is provided with media input and outlet, is injected with the concrete post 30 being made up of concrete in described wellhole 10, and described concrete post 30 is coated on outside heat exchanger tube pipe shaft.
Abandon in prior art, directly heat exchanger tube is passed into the mode of wellhole 10, the substitute is injection concrete in wellhole 10, concrete is made to be coated on the outer pipe shaft of heat exchanger tube, form, after concrete grout solidification, the concrete post 30 that structural strength is high, the external world is applied to the pressure of heat exchanger tube pipe shaft and all itself is undertaken by concrete post 30, after the heat exchanger tube of concrete post 30 cladding, comprcssive strength significantly improves, heat exchanger tube can be passed into deeper of position, underground, and then can further improve the heat exchange efficiency of heat exchanger, heat exchanger tube can adopt lower-cost material to make, also can reduce the cost of structure heat exchanger further.
As preferred side's scheme of the present utility model, described heat exchanger tube is connected with Grouting Pipe 40, and Grouting Pipe 40 constitutes detachable cooperation with heat exchanger tube. Owing to the hole depth of wellhole 10 is deeper, for guaranteeing the accuracy of Grouting Pipe 40 fall depth, concrete is avoided to smash Grouting Pipe 40, described Grouting Pipe 40 is connected with heat exchanger tube, and together down to the setting position of wellhole 10 so that Grouting Pipe 40 is connected with slip casting machine, and to wellhole 10 slip casting, along with the rising of grouting amount, Grouting Pipe 40 can rise therewith, until wellhole 10 stops slip casting after returning slurry.
Being provided with connection support 50 on described heat exchanger tube, the pipe shaft of described Grouting Pipe 40 constitutes threaded cooperation with being connected support 50. When heat exchanger tube drops to the appointment position of wellhole 10, Grouting Pipe 40 is disassembled from support 50, the upper pipe end of Grouting Pipe 40 is connected with slip casting machine, and the elevating mechanism on slip casting machine drives Grouting Pipe 40 to rise along with the rising of grouting amount, until wellhole 10 aperture is returned slurry and stopped slip casting.
Further, described heat exchanger tube includes the first vertical tube 21, the lower pipe end of the first vertical tube 21 is connected to tee T 22, one end mouth of pipe of tee T 22 extends straight down, the other end mouth of pipe bending of tee T 22 upwardly extends and connects with the lower end mouth of pipe of the second vertical tube 23, and the upper pipe end of first, second vertical tube 21,23 respectively constitutes entrance and the outlet of medium;
For guaranteeing that heat exchanger tube can pass into the position that underground is deeper smoothly, the tube chamber place of the mouth of pipe that described tee T 22 extends straight down is provided with plug 60, and plug 60 passes through tube chamber and the inwall with the mouth of pipe place of tee T 22 constitutes sealing and coordinates. When heat exchanger tube passes into deeper position, underground; water in wellhole 10, silt etc. are by tee T 22 and then heat exchanger tube; and then counteract the buoyancy that wellhole 10 is applied to the heat exchanger tube of closing; can ensure that heat exchanger tube is driven underground deeper position; it is driven underground behind deeper position, can extract by the water within heat exchanger tube and silt, and plug 60 is thrown in downwards by the first vertical tube 21 pipe end; and then heat exchanger tube is blocked so that heat exchanger tube forms a tubular structure closed.
Owing to heat exchanger tube is in actual use procedure, increase along with service life, the impurity such as the silt in the silt of the trace in wellhole 10 or medium own can be deposited on the crooked place place of the tee T 22 of heat exchanger tube, in the course of time heat exchanger tube is blocked, for improving the service life of heat exchanger tube, 22 times pipe ends of described tee T are extended precipitation tube 221, described plug 60 is positioned at the lower end tube chamber of precipitation tube 221 and arranges, all of silt impurity is all deposited in this precipitation tube 221, medium in tee T 22 is able to normal circulation, improve actual service life, reduce the maintenance period of heat exchanger tube, the development length of this precipitation tube 221 is at 1m to 1.5m.
The bore of the lower end tube chamber of the precipitation tube 221 cone tubular structure that generally caliber is gradually reduced from top to bottom, the lower nozzle closing in shape lumen wall close fit of the outer wall of described plug 60 and precipitation tube 221, described plug 60 is spherical or circular cone or truncated cone. The close fit that the shape that the shape of above-mentioned plug 60 setting is arranged with the tube chamber of the lower nozzle of precipitation tube 221 is constituted, it is simple to while plug 60 is automatically imported the lower nozzle tube chamber of precipitation tube 221, it is ensured that the sealing of precipitation tube 221.
Owing to heat exchanger tube is in the process passed into wellhole 10, the bottom hole location place of wellhole 10 or close on bottom hole location place and have substantial amounts of silt, for avoiding the hard things such as silt to run into or scratch heat exchanger tube, can pass through to reduce the speed of lower pipe, and the lower pipe end of described precipitation tube 221 is additionally provided with pillar 70, the closing in shape body that described pillar 70 is located at precipitation tube 221 is peripheral, and the lower vessel end closure of pillar 70 and pipe shaft offer connection tube chamber and extraneous through hole 71. Pillar 70 implements the protection of the lower pipe end to precipitation tube 221, and the water in wellhole 10 is entered in precipitation tube 221 by through hole 71, it is ensured that heat exchanger tube imports the position that wellhole 10 is deeper smoothly.
