Abstract
The invention discloses a kind of tensioning hydro-cylinder of improvement, it can strengthen the insulation class of whole cylinder, and the destruction to tensioning hydro-cylinder of effectively avoiding being struck by lightning guarantees the proper functioning of wind-power generating system to reduce cost of equipment maintenance.It comprises cylinder barrel and piston rod, described piston rod two ends are connected with piston head respectively and are connected support ring, described piston head end inserts described cylinder barrel inside, between described piston rod and the described cylinder barrel, be separately installed with black box between described piston head and the described cylinder barrel, it is characterized in that: in the described connection support ring dead ring is installed.
Description
(1) technical field
The present invention relates to be applied to the wind powered generator system field of components, be specially a kind of tensioning hydro-cylinder of improvement.
(2) background technique
Large-scale wind-driven generator is overhead high, be struck by lightning easily, see Fig. 1, its piston rod 2 two ends of common tensioning hydro-cylinder connect piston head 3 and support ring 4 respectively, support ring 4, piston rod 2, piston head 3, cylinder barrel 1 is conducting metal and makes, electric current can be along support ring 4 when wind-driven generator is struck by lightning, piston rod 2, piston head 3 transmits successively, because the gap between piston head 3 and cylinder barrel 1 inwall has only 0.1mm～0.2mm, electric discharge phenomena can appear between piston head 3 and the cylinder barrel 1, thereby the coating on cylinder barrel 1 inwall and piston head 3 surfaces is broken, make the crude out-of-flatness that becomes of the inwall of otherwise smooth, destroyed the necessary operating conditions of black box 5 proper functioning, make tensioning hydro-cylinder oil leakage phenomenon occur, also will destroy black box when serious, cause the interior leakage of oil of tensioning hydro-cylinder serious, cisco unity malfunction, the cost of raising m of e.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of tensioning hydro-cylinder of improvement, it can strengthen the insulation class of whole cylinder, and the destruction to tensioning hydro-cylinder of effectively avoiding being struck by lightning guarantees the proper functioning of wind-power generating system to reduce cost of equipment maintenance.
Its technological scheme is such: it comprises cylinder barrel and piston rod, described piston rod two ends are connected with piston head respectively and are connected support ring, described piston head end inserts described cylinder barrel inside, between described piston rod and the described cylinder barrel, be separately installed with black box between described piston head and the described cylinder barrel, it is characterized in that: in the described connection support ring dead ring is installed.
It is further characterized in that: described dead ring is an epoxy resin.
The tensioning hydro-cylinder of structure of the present invention, it is by installing dead ring additional, and electric current is to the transmission of tensioning hydro-cylinder during the blocking-up thunderbolt; avoided discharging between tensioning hydro-cylinder cylinder barrel and the piston head; thereby protect the safety of tensioning hydro-cylinder, prolonged the working life of tensioning hydro-cylinder, saved the maintaining cost.
(4) description of drawings
Fig. 1 is a common tension cylinder structure schematic representation;
Fig. 2 is a structural representation of the present invention.
(5) embodiment
See Fig. 2, the present invention includes cylinder barrel 1 and piston rod 2, piston rod 2 two ends are connected with piston head 3 respectively and are connected support ring 4, the piston head end of piston rod 2 inserts cylinder barrel 1 inside, between piston rod 2 and the cylinder barrel 1, be separately installed with black box 5 between piston head 3 and the cylinder barrel 1, connect in the support ring 4 dead ring 6 is installed; Dead ring 6 is an epoxy resin; Among Fig. 2,7 is gas port, and 8 is hydraulic fluid port.
Claims (2)
1. the tensioning hydro-cylinder of an improvement, it comprises cylinder barrel and piston rod, described piston rod two ends are connected with piston head respectively and are connected support ring, described piston head end inserts described cylinder barrel inside, between described piston rod and the described cylinder barrel, be separately installed with black box between described piston head and the described cylinder barrel, it is characterized in that: in the described connection support ring dead ring is installed.
