Description
Technical Field
The utility model relates to a vertical U-shaped buried pipe joint device of a ground source heat pump. Is suitable for the field of civil engineering and construction.
Background
In the civil engineering building field of today, because the house building that adopts the heating of ground source heat pump can often be met to the consideration of environmental protection, because the U type joint that two traditional vertical buried pipes of ground source heat pump adopted when the low pipe only the tip links to each other by an iron wire, the wholeness is relatively poor, and U type joint produces great friction with the vertical wall of a well easily in the lower pipe work progress, can lead to the U type joint to drop sometimes, from leading to whole U type pipe to scrap, cause the material loss, consequences such as time limit for a project delay, if insert the horizontal pipe after the constructor does not check out vertical buried pipe pressure is unusual at that time, still can lead to more serious consequences such as follow-up heating effect is unusual.
At present, the U-shaped joint of the vertical buried pipe is mainly connected with two U-shaped pipes by a method of binding iron wires through the holes of the protruding part at the front end of the U-shaped joint, and the U-shaped pipes are also simply and directly bound at the groove of the U-shaped joint by the iron wires.
Disclosure of Invention
The technical problem to be solved by the utility model is as follows: aiming at the existing problems, the vertical U-shaped buried pipe joint device of the ground source heat pump is provided.
The technical scheme adopted by the utility model is as follows: the vertical U-shaped buried pipe joint device of the ground source heat pump is characterized in that: the joint device comprises a columnar joint main body and a joint front end which is arranged at the lower end of the joint main body and can reduce friction resistance;
a plurality of U-shaped channels are formed in the connector device, and holes at two end ports of the U-shaped channels are located on the upper end face of the connector main body.
The connector main body is a cylinder, and the front end of the connector is hemispherical.
The diameter of the joint main body is 110mm, and the length of the joint main body is 80 mm; the diameter of the front end of the joint is 110 mm.
The diameter of the port hole of the U-shaped channel is 25 mm.
The distance between the circle center of the port hole of the U-shaped channel on the upper end surface of the connector main body and the circle center of the other adjacent port hole is 50 mm.
The upper end face of the head main body is provided with a groove which can be connected with the lower pipe auxiliary rod.
The utility model has the beneficial effects that: the connector device is internally provided with n (n is more than or equal to 2) U-shaped channels which can be connected with 2n PE pipes to form n U-shaped pipes, meanwhile, the connector device is an integral body and has better integrity, the lower end of the connector device is provided with a connector front end capable of reducing friction resistance, the connector is not easy to damage during pipe laying, the pipe laying resistance is small, and the connector device is not easy to fall off due to the connection of the 2n PE pipes.
The joint device can be connected with at least 4 PE pipes, so that the joints can be effectively prevented from falling off, the U-shaped channels are all positioned on the inner wall of the joint device, a certain distance is reserved between the U-shaped channels and the outer wall of the joint device, the U-shaped channels are protected from being damaged, and the risk of pipe laying failure is greatly reduced.

Detailed Description
The embodiment is a vertical U-shaped buried pipe joint device of a ground source heat pump, which is used for being connected with a PE pipe to form a U-shaped pipe. The joint device in this example has a cylindrical joint body and a hemispherical joint tip formed at the lower end of the joint body, which can reduce frictional resistance between the joint and the hole wall when the pipe is being laid down, and has a thickness to prevent the joint from being broken when the pipe is being laid down.
In this example, 2U-shaped channels are formed in the connector device, the port holes at both ends of the U-shaped channels are located on the upper end surface of the connector main body, and the four port holes of the two U-shaped channels are uniformly distributed on the upper end surface of the connector main body.
In this embodiment U type passageway comprises the circular arc section and two straightway that connect in the circular arc section both ends, and the passageway internal diameter and PE outside of tubes footpath looks adaptation, straightway ensure to have sufficient length in the U type passageway and make PE pipe hot melt firm in connection.
In the embodiment, the diameter of the cylindrical joint main body is 110mm, and the length is 80 mm; the diameter of the front end of the hemispherical joint is 110 mm; the inner diameters of the U-shaped channel and the port holes are both 25mm, and the distance between the adjacent port holes (between the centers of the two holes) on the upper end face of the joint main body is 50 mm. The embodiment ensures that a certain thickness exists between the outside of the U-shaped channel inside the joint device and the outer wall of the joint device, and prevents the joint from being damaged when the pipe is put down.
In this example, a groove is formed on the upper end surface of the joint main body, and the pipe is lowered by inserting the pipe-lowering auxiliary rod into the groove on the joint device, so that the pipe is manually lowered by a machine.
The above-mentioned embodiments are only used for explaining the inventive concept of the present invention, and not for limiting the protection of the claims of the present invention, and all the insubstantial modifications of the present invention using this concept shall fall within the protection scope of the present invention.
