Description
Technical field
The present invention relates to field of oil drilling, especially a kind of resistivity heater.
Background technology
At present, oil-well drilling equipment resistivity generally uses heat gun in maintenance, will be covered in resistivity antennae shell
Upper epoxy resin carries out cure package.In atmosphere, heat scatters and disappears comparatively fast, epoxy resin cure for exposure during due to heat gun operation
Package speed is slow, and is unable to reach cure package effect under cold operating environment, causes resistivity maintenance to there is hidden danger of quality.
The content of the invention
Thermal loss and the good resistivity use of heating effect are reduced the technical problem to be solved in the present invention is to provide a kind of
Heater.
In order to solve the above-mentioned technical problem, the present invention includes the round bar body being spliced by upper tube half and lower tube half, described
Several springs are provided between upper tube half and lower tube half, the upper tube half and lower tube half are also connected to by several sunk screws
Together, wherein sunk screw top is smooth shaft, and lower thread is connected in lower tube half, and the upper tube half can be along countersunk head spiral shell
The micro movement of smooth shaft in portion is nailed on, the upper tube half is one short semicanal and n a long semicanal, the lower half successively from left to right
Pipe is n long semicanals and a short semicanal successively from left to right, wherein short semicanal internal symmetry provided with two short grooves for
Shorter heat-generating pipe is placed, the long semicanal internal symmetry is provided with two long recess for the longer heat-generating pipe of placement.
The beneficial effects of the invention are as follows：The present invention it is safe and reliable, it is simple in construction, it is easy to assembly, can be to resistivity antennae outside
Shell epoxide-resin glue carries out cure package, can effectively play heat effect, it is possible to decrease the heat in heating process scatters and disappears.

Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description：
Referring to Fig. 1 to Fig. 5, resistivity of the invention includes the circle being spliced by upper tube half and lower tube half with heater
The body of rod, is provided with several springs 1, the upper tube half and lower tube half also pass through several countersunk heads between the upper tube half and lower tube half
Screw 2 is linked together, and wherein the top of sunk screw 2 is smooth shaft, and lower thread is connected in lower tube half, the upper tube half energy
Enough smooth shafts along the top of sunk screw 2 are micro to be moved, and the upper tube half is one short semicanal 3 and n successively from left to right
Long semicanal 4, the lower tube half is n long semicanals 4 and one short semicanal 3 successively from left to right, wherein the internal symmetry of short semicanal 3 is set
Have two short groove 31 to place shorter heat-generating pipe, the long internal symmetry of semicanal 4 provided with two long recess 41 with
In the longer heat-generating pipe of placement.
Long semicanal and short semicanal are staggeredly placed in the upper and lower semicanal of the present invention, and are fixed together by countersunk head screw；Will
Heat-generating pipe is placed in the long and short groove of long semicanal and short semicanal, spring be placed on above and below between two semicanals so that it is of the invention plus
Hot charging is equipped with certain stroke；Heater is put into resistivity hydrophthalmia, the stroke of heater diameter prevents resistance
Occur gap between rate hydrophthalmia and heater, reduce thermal loss, firing rate is faster, evenly.
In summary, present disclosure is not limited in the above embodiments, and those skilled in the art can be
Propose other embodiments within the technological guidance's thought of the present invention, but these embodiments be included in the scope of the present invention it
It is interior.
