Device for quickly descending U-shaped pipe of ground source hot well into well

Abstract

The invention discloses a device for quickly descending a ground source hot well U-shaped pipe into a well, a U head is integrally formed at the bottom end of a U-shaped pipe main body, a counterweight body is integrally formed on the bottom end face of the U head, and a connecting clamping groove is formed in one side of the counterweight body; the anti-drag angle body is integrally formed and arranged on one side of the connecting body, the other end of the connecting body is integrally formed and provided with the adapter clamping body, and the two ends of the adapter clamping body are symmetrically provided with locking clamping grooves; through the arrangement of the counter weight body and the resistance reduction angle body, when pipe descending construction is carried out, the pipe descending device has the main advantages that pipe descending is rapid, pipe descending time is saved, pipe descending is smoother, the damage rate is low, efficiency is high, and unnecessary economic losses are avoided; and through cooperative use of the locking assembly and the auxiliary assembly, the anti-drag angle body can be quickly disassembled and assembled, that is, the anti-drag angle body can be correspondingly regulated and controlled according to actual pipe descending construction requirements, the construction requirements are met, and the construction economic benefits are improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a device for quickly lowering a U-shaped tube in a ground source heat well. Background technique [0002] With the continuous development of the construction industry, improving the economics of projects has become the mainstream demand. During the construction of buildings, due to the characteristics of groundwater warm in winter and cool in summer, the groundwater ground source heat pump system has higher cooling / heating efficiency than conventional air conditioning systems. , is an energy-saving and environmentally friendly renewable energy technology; with the global energy crisis and the intensification of environmental problems, groundwater ground source heat pump technology has received more and more attention, and has been promoted and applied all over the world. One of the key points in ground source heat pump engineering. [0003] The depth of the lower p...

Problems solved by technology

[0003] The depth of the lower pipe determines how much heat is taken, so the depth of the lower pipe must be guaranteed, but in the actual construction process of the lower pipe, it will be affected by the buoyancy and the resistance of the pipe head, which will affect its first speed, and when the pipe head reaches the target position The stability is poor, which brings difficulty to the construction, affects the construction process, and reduces the economic benefits of construction
