Spot width on device, installs secondary reflection mirror simultaneously, poly- for the radiation secondary focusing being irradiated to heat dump entrance, improving
Light is heated to higher temperature than by collection thermal medium.
For ensureing the solar radiation entering heat dump opening is effectively converted into the heat of thermal-collecting tube internal flow medium,
Need the secondary reflection mirror to heat dump and thermal-collecting tube is carried out it is ensured that secondary reflection mirror has good reflectivity, thermal-collecting tube
Surface clean enough.
Compared with slot type photo-thermal power generation technology, the heat dump of linear Fresnel is highly of a relatively high, props up for reducing heat dump
Post intensity improves the stability of heat dump simultaneously, and heat dump column both sides are connected with ground using drag-line, and these drag-lines can be right
Near heat dump and drag-line, the cleaning of speculum brings obstruction.
Content of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of linear Fresnel thermal-arrest
Device heat dump fixed structure, solves linear Fresnel collecting system heat dump fixed structure to asking that cleaning is made troubles
Topic.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of linear Fresnel heat collector heat dump fixing means is it is characterised in that arrange adjacent two with trend
Heat collector is one group, is directly connected to by the drag-line perpendicular to heat collector length direction, one group of thermal-arrest in group between heat dump
The primary event mirror column of device both sides exceed primary event mirror rotating shaft plane certain distance and with close heat dump drag-line
Connect, form the complete drag-line from heat collector two heel post to heat dump, heat dump is fixed.
Wide interval is adopted between primary event mirror mirror field it is ensured that heat dump cleaning Vehicle 6, primary event mirror cleaning Vehicle 7 in group
And safeguard the current of vehicle, adopt narrow interval between mirror field between adjacent sets, to save space.
The utility model additionally provides a kind of linear Fresnel heat collector heat dump fixed structure, each heat collector bag
Include heat dump 1 and the primary event Jing Jingchang being made up of primary event mirror 3, heat dump 1 is located at the top of primary event Jing Jingchang
Central authorities, move towards heat collector is set to one group it is characterised in that fixed structure is included for connecting in group to adjacent two together
Drag-line 51 between the heat dump of the level perpendicular to heat collector length direction of heat dump 1, and be used for connecting heat dump 1 and be somebody's turn to do
The primary event mirror column drag-line 52 of a nearlyer heat dump in the primary event mirror column 4 of group heat collector both sides.
The described primary event mirror column 4 being connected with heat dump 1 exceeds primary event mirror 3 rotating shaft plane certain distance.
Walk below heat dump cleaning Vehicle 6 drag-line 51 between heat dump, stretch to the cleaning pipeline 61 not tension cable of heat dump 1
Hinder；By not inhaled when the height of primary event mirror column 4 ensures that primary event mirror cleaning Vehicle 7 is cleaned to primary event mirror 3
The obstruction of the primary event mirror column drag-line 52 of hot device.
Compared with prior art, the beneficial effects of the utility model are: by improving primary event mirror mirror field column drag-line
Fixing height is it is ensured that minute surface cleaning device can be carried out with the speculum row near column；Two heat dumps in group
Between adopt jump stay, it is to avoid the impact to cleaning Vehicle and the maintenance work safeguarding vehicle for the suspension cable；Adopt between adjacent sets
With narrow interval, improve land utilization ratio, reduce the land seizure of light thermo-power station.
