Description
Technical field
The present invention relates to bus crest slab technical field more particularly to a kind of solar energies having thermal insulation protection to natural gas bottle
Lie prostrate solar panel bus crest slab.
Background technology
Sui the growth of energy demand and the continuous deterioration of environmental pollution, is polluted to air using clean energy resource reduction
New-energy automobile become development of automobile important directions.
Clean energy resource includes solar energy, natural gas.Solar energy resources are abundant, not only can freely use, but also without transport, to ring
Border is that country calls the regenerative resource used energetically without any pollution.But it is less efficient due to solar cell, while
The limited area of photovoltaic cell is installed on car, institute's generated energy cannot fully meet demand of the vehicle to electric power, so purely with
Solar energy is that the automobile of power hardly enters practical application, can only be used as a kind of supplementary energy on automobile；Natural gas
It is a kind of clean energy resource, opposite gasoline, burning is more complete, and generated harmful exhaust is low more than gasoline after burning, uses day
Right gas can meet the needs of vehicle power is to the energy, in addition use cost is low, so natural gas bus has become car development
Important directions.Ensureing that natural gas bus can continuously drive for a long time, the gas cylinder volume of natural gas-storing is generally large, in order to
It is unlikely to reduce effective use space of natural gas bus, natural gas bottle is typically mounted on bus crest slab, however bus crest slab
It is expose to sunlight most places and the summer complete highest place of vehicle temperature, causes to be mounted on natural on bus crest slab
Gas cylinder and the gas transmission system being connected in above work at high temperature in summer back warp Chang Lianxu, will be to natural gas bottle and natural gas bus
Safety have an adverse effect, therefore gas cannot fill too full in natural gas bottle, and air pressure cannot be too high, this has become restriction
The major reason of natural gas bus mileages of continuation.How to make to be mounted on natural gas bottle on bus crest slab to lead from summer sunlight
Cause high temperature influence, improve natural gas bottle in natural gas effective charge weight, increase the mileages of continuation of natural gas bus, at
For bus industry problem anxious to be resolved.
Invention content
The present invention is intended to provide a kind of solar photovoltaic cell panel bus crest slab having thermal insulation protection to natural gas bottle, with solution
Problem certainly set forth above.
A kind of solar photovoltaic cell panel car having thermal insulation protection to natural gas bottle is provided in the embodiment of the present invention
Ceiling, the ceiling by solar photovoltaic cell panel, lithium battery group, natural gas bottle, protective plate, bus crest slab holder, car outside
Shell is formed；Fixed natural gas bottle is installed on bus crest slab holder and lithium battery group, natural gas bottle are completely isolated with lithium battery group
It opens；Protective plate is installed on natural gas bottle and lithium battery group, bus crest slab shell is covered on protective plate, in bus crest slab shell
Upper installation solar photovoltaic cell panel；The solar photovoltaic cell panel uses dye-sensitized solar cells, in configuration aspects,
It includes light anode, to electrode and electrolyte, wherein light anode and is oppositely arranged to electrode, is sandwiched between liquid electrolyte；It should
Light anode includes FTO substrates, and TiO is equipped in FTO substrate surfaces2Laminated film；The TiO2Laminated film includes BaTiO3/
MoS2/TiO2Nanometer sheet heterojunction structure and TiO2Nano particle；The TiO2What laminated film was formed by：By in FTO substrates
Surface screen-printed TiO2Composite mortar, to form the TiO2Laminated film.
The technical solution that the embodiment of the present invention provides can include the following benefits：
The present invention is by solar photovoltaic cell panel, lithium battery group and natural gas bottle reasonable Arrangement in natural gas bus ceiling
On, solar photovoltaic cell panel is converted into electric energy by the solar energy for being emitted onto above, and effective protection is arranged in passenger-car roof
Natural gas bottle on canopy is influenced from the heat radiation of sunlight, improves the safety of natural gas bottle and gas transmission system work.This
Outside, the electric energy that solar photovoltaic cell panel is sent out can enter lithium battery group, the illumination for car and air-conditioning, become natural gas visitor
Therefore the solar energy supplementary energy of vehicle, natural gas bus also become natural gas --- solar hybrid car.
The present invention provides a kind of effective thermal insulation protection pattern for the natural gas bottle on natural gas bus ceiling.
The present invention is suitable for natural gas bus or natural gas --- solar hybrid car.
The additional aspect of the present invention and advantage will be set forth in part in the description, and will partly become from the following description
Obviously, or practice through the invention is recognized.It should be understood that above general description and following detailed description are only
It is exemplary and explanatory, the present invention can not be limited.

Ultra-pure water and ethyl alcohol eccentric cleaning obtain product drying at 70 DEG C and for 24 hours, obtain the TiO2Nanometer sheet；By the molybdic acid of 0.3g
The oxalic acid of sodium, the thioacetamide of 0.4g and 0.5g is dissolved in respectively in 20ml deionized waters, magnetic agitation 15min, respectively shape
At homogeneous solution；Then, the thioacetyl amine aqueous solution of 20ml is poured slowly into the sodium molybdate solution of 20ml, while magnetic agitation
10min forms mixed solution A, then mixes the oxalic acid solution of 20ml and mixed solution A, and ultrasonic 20min keeps solution abundant
Reaction forms mixed solution B；Mixed solution B is transferred in 100ml autoclaves and intact sealing, reaction kettle is put into
30h is kept the temperature at a temperature of 200 DEG C；It waits for that the sediment generated in reaction kettle is collected by centrifugation after reaction, after cleaning, then true
Dry 10h will be deposited at 60 DEG C in empty drying box, and then under protection of argon gas, 630 DEG C of annealing 75min obtain MoS2；By hydrogen
Barium monoxide is completely dissolved in ultra-pure water, is configured to the solution of a concentration of 14mM, 60ml, is then added into reaction kettle, presses
According to molar ratio, TiO obtained above is added into reaction kettle2Nanometer sheet and MoS2, after magnetic agitation 50min, then 210 DEG C of guarantors
Warm 35h waits for that cooled to room temperature after completion of the reaction, products therefrom are washed repeatedly with the hydrochloric acid solution of 0.1M and deionized water,
Then it is dried to obtain the BaTiO3/MoS2/TiO2Nanometer sheet heterojunction structure；By BaTiO3/MoS2/TiO2Nanometer sheet hetero-junctions
Structure and TiO2Nano particle is configured to TiO2Composite mortar；Light anode substrate is FTO substrates, is cut, is cleaned up, then
Configure the TiCl of 0.04M4The FTO substrates cleaned up are put into TiCl by aqueous solution4In aqueous solution, 1h is kept at 80 DEG C, is taken
Go out, rinsed with deionized water, FTO substrates are put into Muffle furnace repeatedly then, anneal 1h at 400 DEG C；Using silk screen print method
By TiO2Composite mortar is coated in processed FTO substrates, and after reaching required thickness, the FTO substrates of the good slurry of spin coating are existed
Then 260 DEG C of dry 5h calcine 40min, 310 DEG C of calcining 15min, 360 DEG C of calcining 50min, 450 DEG C of calcinings at 290 DEG C
30min, 500 DEG C of calcining 20min；FTO substrates after calcining are immersed in the acetonitrile of 0.05mM dyestuffs N-719 and the tert-butyl alcohol mixes
In solution, acetonitrile and tert-butyl alcohol volume ratio are 1:1, it stops for 24 hours, is dried after taking-up, obtain the light anode；
Step 2, it prepares to electrode；
Step 3, it encapsulates.
