Abstract

The utility model relates to a heat conductive protection device. The heat conductive protection device 1 is a cube with four arc corners; the four corners of the heat conductive protection device 1 is provided with a through hole 2; in the construction of the ground source pump vertically burying pipes, the heat conductive pipe protection device 1 is sleeved with the heat conductive pipe 3 to make the heat conductive pipe protection device be blocked at the connection between a dual-U head 4 and the heat conductive pipe3; the internal side of the four heat conductive pipe 3 is a cylindrical space, the size of which meets the requirements of the drilling head and the drilling head can be propped in the space; the utility model makes the heat conductive pipe protection device be tightly blocked and matched with the dual-U joint and does not drop; meanwhile, makes the drilling head always act in the positive middle of the dual-U head, which is not easy to damage the connection between the dual-U head and the heat conductive pipe; meanwhile, the utility model has simple process and low cost; the utility model is suitable for the construction of that the ground source heat pump vertically buries the pipes.

Description

The heat conductive tube preventer

Technical field the utility model relates to a kind of pipeline construction accessory, a kind of heat conductive tube preventer in specifically a kind of earth source heat pump engineering ground pipe laying process.

Technical background

In the prior art, in the vertical buried pipe construction process of earth source heat pump, especially in the vertical buried pipe construction process with the double-H groove weld head, traditional method is the centre that drill bit is withstood on the double-H groove weld head, source, ground underground pipe is headed into underground because vertically pipe laying is generally darker, be difficult in the well-digging process guarantee wellhole fully straight down, descend the pipe process can cause the borehole wall unbalanced to the friction of pipe like this, because wellhole is darker, water can not be ignored the buoyancy that the double-H groove weld head produces simultaneously.Under the influence of above two kinds of factors, the drill bit of rig is difficult to guarantee all to withstand on the middle of double-H groove weld head in the whole process of following pipe, and the double-H groove weld head is that hot melt connects with being connected of heat conductive tube, because the bad situation in the drilled crown, hot melt joint can appear in this deviation.

The model utility content

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of simple in structure, low price, the heat conductive tube preventer of easy processing.

The technical solution adopted in the utility model is: a kind of heat conductive tube preventer is characterized in that: the heat conductive tube preventer is the square body of four arc round angles, is provided with through hole at four angles of heat conductive tube preventer.

The beneficial effects of the utility model are: owing to adopt above-mentioned structure, the heat conductive tube preventer can be closely cooperated with double-U-shaped joint clamping not to come off, make drill bit act on the middle of double-H groove weld head all the time simultaneously, the joint of survivable double-H groove weld head and heat conductive tube, the utility model technology is simple simultaneously, cost is low; The utility model is applicable to the construction of the vertical buried pipe process of earth source heat pump.

Description of drawings

Fig. 1 is a plan view organigram of the present utility model;

Fig. 2 is the plan view of Fig. 1;

Fig. 3 is the organigram of the utility model and heat conductive tube assembling.

The embodiment Figure of description is the optimal way that the utility model is implemented, and below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 1, 2: heat conductive tube preventer 1 of the present utility model is the square body of four arc round angles, is provided with through hole 2 at four angles of heat conductive tube preventer 1.

Fig. 3 is the organigram of the utility model and heat conductive tube assembling, in the construction of the vertical buried pipe process of earth source heat pump, heat conductive tube preventer 1 is sleeved on the heat conductive tube 3, make it to be stuck in the joint of double-H groove weld head 4 and heat conductive tube 3, four heat conductive tube 3 inboards are column type space, garden, size meets the drill bit requirement, and drill bit can be withstood on wherein.

It is raw material that product of the present utility model adopts plastics, by the moulding of mould pressing one-time, high about 20 centimetres, earlier the heat conductive tube preventer is stuck in the joint of double-H groove weld head and heat conductive tube during use, then drill bit is withstood in the middle of the heat conductive tube preventer, can descend pipe, the utility model can be tight with drill bit and the combination of double-H groove weld head like this, difficult drop-off has also improved the efficient and the quality of construction simultaneously greatly.

More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limit practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
