BeschreibungDescription

Problemstellung: Die im Schutzanspruch beschriebenen Erdsondenköpfe (Fig.Problem: The geothermal probe heads described in the protection claim (Fig.

1 und Fig. 2) dienen zur besseren und in erster Linie zur zerstörungsfreien Einfuhrung von PE oder PP-Rohren in vorgebohrte Erdlöcher, welche gekoppelt mit einer Wärmepumpe für die Wärmeenergiegewinnung eingesetzt werden.1 and Fig. 2) serve for better and primarily non-destructive introduction of PE or PP pipes into pre-drilled holes in the ground, which are used in conjunction with a heat pump for the generation of thermal energy.

Akatherm Höhn hat für die Problemlösung die im Schutzanspruch beschriebenen Erdsondenköpfe (Fig. 1 und Fig. 2) entwickelt. Die Erdsondenköpfe bestehen aus vier oder mehreren PE oder PP-Rohren (1), die über eine 180° Rohrumlenkung paarweise miteinander durch Heizelementstumpfschweißnähte fest verbunden sind. Die einzelnen Rohrpaare werden in einem Winkel versetzt zueinander in ein Harz-Feinkies-Gemisch (2) eingebettet und dadurch in ihrer Lage fixiert. Die Spitze des Erdsondenkopfes ist konisch (4) ausgeführt. To solve the problem, Akatherm Höhn has developed the geothermal probe heads (Fig. 1 and Fig. 2) described in the protection claim. The geothermal probe heads consist of four or more PE or PP pipes (1) which are firmly connected to one another in pairs by means of heating element butt welds via a 180° pipe deflection. The individual pipe pairs are embedded in a resin-fine gravel mixture (2) at an angle to one another and are thereby fixed in position. The tip of the geothermal probe head is conical (4).

Dadurch, daß die Rohre in dem Harz-Feinkies-Gemisch (2) eingebettet und fest fixiert sind, schützen sie die medienführende Rohrleitungen beim Einführen in die Erdbohrungen vor Beschädigungen (z. B. Kratzer). Weiter wird das Einziehen der Rohre (1) in die Bohrlöcher erleichtert, da das Harz-Feinkies-Gemisch (2) das spezifische Eigengewicht der Rohre im Umlenkbereich erhöht wird. Dieses ist besonders bei anstehendem Grundwasser von Bedeutung.Because the pipes are embedded in the resin-fine gravel mixture (2) and firmly fixed, they protect the media-carrying pipelines from damage (e.g. scratches) when they are inserted into the boreholes. Furthermore, pulling the pipes (1) into the boreholes is made easier because the resin-fine gravel mixture (2) increases the specific weight of the pipes in the deflection area. This is particularly important when there is groundwater.

Weiter Ausführungsvarianten: Bei sehr hohem Grundwasserstand ist es von Vorteil, dieFurther design variants: If the groundwater level is very high, it is advantageous to

Erdsondenköpfe so wie in Bild (Fig. 2) dargestellt, auszuführen. Die Erdsondenköpfe werden in diesem Fall mittig mit einer Runden Aufnahme (10) für das Einstecken einer Führungsstange (11) versehen. Zusätzlich werden an zwei sich gegenüberliegenden Seiten gerade Flächen (12) geschaffen, die es der Flüssigkeit ermöglichen zwischen der Bohrlochwand und dem Erdsondenkopf nach oben zu strömen.Geothermal probe heads are designed as shown in the picture (Fig. 2). In this case, the geothermal probe heads are provided with a round holder (10) in the middle for inserting a guide rod (11). In addition, straight surfaces (12) are created on two opposite sides, which allow the liquid to flow upwards between the borehole wall and the geothermal probe head.

Claims (1)

Akatherm Höhn Erdsondenköpfe (Fig. 1 und Fig. 2) für Erdabsorberanlagen kennzeichnen sich dadurch, daß vier oder mehr PE oder PP-Rohre der Rohrkennzahl SDR 11 in verschiedenen Rohrdurchmessern, paarweise über 180° Rohrumlenkungen miteinander verbunden, und die Rohrpaare in einem Winkel zueinander versetzt angeordnet, in einem Schutzkörper aus einem Harz-Feinkies-Gemisch (2) eingebettet sind. Akatherm Höhn geothermal probe heads ( Fig. 1 and Fig. 2) for geothermal absorber systems are characterized by the fact that four or more PE or PP pipes of pipe code SDR 11 in different pipe diameters, connected in pairs via 180° pipe deflections, and the pipe pairs arranged offset at an angle to each other, are embedded in a protective body made of a resin-fine gravel mixture ( 2 ).
