Description of the drawings
Fig. 1 is the structural schematic diagram of one embodiment of the thermal insulation casing of the utility model.
Specific implementation mode
The embodiment of the thermal insulation casing component of the utility model：
The thermal insulation casing component of the utility model includes at least two thermal insulation casings being vertically superimposed, the tool of thermal insulation casing
Body structure is as shown in Figure 1, including the columned sleeve body 1 that axis vertically extends, sleeve body 1 is by length
The seamless steel pipe of 600-12000mm is made, and the internal diameter of seamless steel pipe is 200mm ~ 1500mm.It is set on the peripheral surface of sleeve body 1
It is equipped with insulating layer 2, the material of insulating layer is fiberglass reinforced plastics.
The thermal coefficient of fiberglass reinforced plastics is small, and the 1% of insufficient steel, meet underground coal mine cooling requirement of engineering.Simultaneously
It is difficult that thermal insulation casing overall weight, project cost and operation can be greatly lowered in the 1/4 of fiberglass reinforced plastics degree deficiency steel
Degree.Fiberglass reinforced plastics has excellent heat-insulating property and tension, compression strength, and set is molded over using pressure stochastic distribution
The middle part of tube body 1, more so that insulating layer 2 and the combined strength bination of sleeve body 1 are higher.
The insulating layer made of fiberglass reinforced plastics can not only meet the heat preservation demand of casing, also while have knot
The advantage that structure is simple, compression strength is high, the insulating layer of lightweight further avoid that thermal insulation casing weight is excessive to be set beyond drilling well
The problem of standby bearing capacity, conducive to being normally carried out for heavy caliber deep-well construction is ensured.
For ease of the connection of multiple thermal insulation casings, insulating layer 2, two thermal insulation casings are stretched out in the axial both ends of sleeve body 1
End by accordingly stretching out insulating layer is welded and fixed together.Specifically, lower section guarantor is close in the lower face of top thermal insulation casing
The upper surface of warm sleeve, then the corresponding end of two thermal insulation casing middle sleeve ontologies 1 is welded and fixed.
In the present embodiment, the upper end of sleeve body 1 stretches out insulating layer 800mm and forms external part 21, sleeve body 1
Lower end stretch out insulating layer 200mm and form lower external part 22.Perforation casing sheet in left-right direction is provided on upper external part 21
The through-hole 23 of 1 wall thickness of body.When assembling thermal insulation casing, supporting rod is installed in through-hole 23 to facilitate the assembling of thermal insulation casing.
Specifically, supporting rod is installed in through-hole 23, is hung thermal insulation casing on the well head edge of construction by supporting rod
It goes up and external part 21 is made to expose well head, reuse the end that loop wheel machine slings another thermal insulation casing, and keeps two thermal insulation casings opposite
To just, being subjected to again later.One section of one section of ground will be welded thermal insulation casing to thermal insulation casing by top in this way
Length meet the requirements.So this upper end stretches out heat preservation layer height and is more than the setting form that heat preservation layer height is stretched out in lower end,
On the basis of ensure that thermal insulation casing convenient for assembling, the setting area of insulating layer 2 ensure that the maximum extent.
After the completion of welding, welding is needed to fill the through-hole 23, and live heat preservation is carried out to the naked pipe section for stretching out insulating layer 2
Processing.The concrete operations of live isothermal holding are as follows：The brush epoxy resin on the peripheral surface of naked pipe section part, then in the outer of naked pipe
All surface buckles set prefabricated fiberglass reinforced plastics hemizygous pipe, are fixed on fiberglass reinforced plastics hemizygous pipe using steel band
After in sleeve body 1, the glass wool cloth finally impregnated through epoxy resin in outermost layer winding is completed to thermal insulation casing component
It makes.Thermal insulation casing component after completing can be in tripping in drilling to assemble another thermal insulation casing above it.
Fiberglass reinforced plastics hemizygous pipe has the medial surface of at least two, and at least two hemizygous pipes that can surround and naked pipe
Peripheral surface shape coincide adaptation cylinder.
In other embodiments, the size of sleeve body can also be other values；Insulating layer can also be by other thermal insulating materials
Material is made；When sleeve body size is smaller, it is adjacent that sleeve body both ends can also process the realization of the connection structures such as screw thread, buckle
The connection of two thermal insulation casings.
