Ground source heat pump hole well construction device with residual material collecting function

Abstract

The invention discloses a ground source heat pump hole well construction device with a residual material collecting function. The ground source heat pump hole well construction device comprises a positioner, a power frame, a base and a protective cover, the base and the protective cover are both fixedly installed on the ground, the positioner comprises a positioning ring and a fixing seat, the fixing seat is fixedly installed above the protective cover, the positioning ring is installed above the fixing seat in a sliding mode, coils are fixedly installed at the front end and the rear end of the interior of the positioning ring, compared with a current construction device, the poisoner, a shock absorber, a collecting box, a cleaner and the protective cover are additionally arranged, the trouble that a constructor manually supports a drill rod is avoided through the positioner, the vibration amplitude of the drill rod can be effectively reduced through the shock absorber, the phenomenon of muddy water turbulence can be greatly avoided through cooperation of the protective cover and the collecting box, waste generated in the construction process is collected and treated in a unified mode, and the surface of the drill rod can be cleaned through the cleaner.

Description

technical field [0001] The invention relates to the technical field of geothermal utilization, in particular to a geothermal heat pump well construction device with the function of collecting residual materials. Background technique [0002] With the development of society, there are more and more new energy sources that are both environmentally friendly and energy-saving. Among them, ground source heat pumps, as the most efficient household heating and cooling systems, will have broad application and development prospects in China. , but the principle of ground source heat pumps is to obtain low-grade heat from natural air, water or soil, and output available high-grade heat energy through electricity. Therefore, ground source heat pumps are mainly carried out underground, and must be drilled to It can carry out heat transfer. In order to ensure the quality of the well, a large number of ground source heat pump well construction devices have appeared on the market. [0003...

AI Technical Summary

Problems solved by technology

[0003] Therefore, the existing ground source heat pump well construction devices usually do not have the function of collecting waste materials, and a large amount of residual materials will be generated during the drilling construction process, so that the muddy water will flow turbulently, and finally the entire working environment will become extremely dirty. On the one hand, it affects the construction of the staff, and on the other hand, it increases the difficulty of subsequent cleaning. At the same time, the current ground source heat pump well construction device has great deficiencies in the positioning and connection of drill pipes. For example, "CN201420149941. Rod device ground source heat pump drilling equipment", which discloses a technology for automatically replacing drill pipes, but although this device solves the troublesome problem of rod replacement, it is not suitable for small and medium-sized construction drilling teams because of its high cost. In pursuit of practicality and cost-effectiveness, most small and medium-sized construction drilling teams still use old-fashioned drilling devices during the construction of ground source heat pump wells. However, the current old-fashioned drilling devices basically do not have automatic positioning functions, and they need to manually move the two sets of drills. The rods are aligned, and then one group of drill rods is driven to rotate through the power device, so as to achieve the purpose of connecting the two groups of drill rods. This connection method not only reduces the work efficiency, but also increases the labor load of the staff.

[0004] In addition, the current ground source heat pump well construction device often vibrates during the working process, which may reduce the quality of the well and the life of the drill pipe. At the same time, the drill pipe needs to go deep underground tens of meters or even 100 meters, this depth may cause a certain amount of bending of the drill pipe, which will cause the actual verticality of the hole to be different from the predicted verticality
