As an embodiment of the present invention, the longitudinal sunshade tube 41 is disposed in an inclined manner, and two sides of the longitudinal sunshade tube 41 are provided with grooves 411;
when the greenhouse is in operation, when the temperature in the greenhouse is higher than the outside temperature in the night environment, a certain amount of water drops are generated on the film 3 due to the difference between the inside temperature and the outside temperature, at the moment, the water drops on the film 3 slide along the inner wall of the film 3 under the action of self gravity, at the moment, the longitudinal sun shading pipe 41 is integrally arranged in an inclined manner and forms an angle of 30-45 degrees with the horizontal plane, so that the water drops accumulated on the inner wall of the film 3 contact the side surface of the longitudinal sun shading pipe 41 in the sliding process along the film 3, the water drops contact the groove 411 on the side surface of the longitudinal sun shading pipe 41, the water drops slide into the groove 411 and continue to slide in the groove 411 and do not slide towards the two sides of the greenhouse along the groove 411, and the problem that the water drops accumulated on the inner wall of the film 3 possibly drop downwards onto crops due to the increase of the volume of the water drops are avoided, meanwhile, the influence of water drops formed on the inner wall of the film 3 on the light transmittance of external illumination is avoided, the temperature of the greenhouse can be lower than the temperature expected to be adjusted, and the growth and development of crops are retarded or even not developed.
As an embodiment of the present invention, the groove 411 is close to one side of the inner wall of the film 3, and the width of the groove 411 is smaller than that of the cavity 43;
in operation, because the width of recess 411 is less than the width of cavity 43, and recess 411 is close to in the film 3 inner wall, consequently after water droplet drippage on the film 3 inner wall in recess 411, the water droplet can not contact with the black solution outside pipe wall that flows in the vertical sun tube 41 when flowing in recess 411, thereby avoided the water droplet that flows in recess 411 to vertically shelter from the heat that flows in the sun tube 41 and absorb in the black solution, and then the heat that stores in the black solution that makes the vertical sun tube 41 that shelters from and flow is not enough, lead to the big-arch shelter night condition under because the heat that vertically shelters from sun tube 41 and flow in the black solution in the reservoir is not enough, the heat that releases also appears falling night, thereby be less than the suitable growing temperature of crops when leading to the inside temperature of big-arch shelter night, be not convenient for the growth of crops.
As an embodiment of the present invention, the transverse sunshade tube 42 and the longitudinal sunshade tube 41 are both made of an elastic transparent material;
when the greenhouse is in work, when the external illumination intensity is different, the external illumination has different influences on the temperature in the greenhouse, when the temperature in the greenhouse needs to be reduced, the black solution is pumped into the transverse sun shading pipe 42 and the longitudinal sun shading pipe 41 through the water suction pump, at this time, because the transverse sun shading pipe 42 and the longitudinal sun shading pipe 41 are both made of elastic transparent materials, and the transverse sun shading pipe 42 and the longitudinal sun shading pipe 41 are in a flat bonding state when air and the black solution are not introduced, when the black solution and the air with different volumes are conveyed between the transverse sun shading pipe 42 and the longitudinal sun shading pipe 41 according to the change of the external illumination intensity, because the volume of the black solution conveyed into the transverse sun shading pipe 42 and the longitudinal sun shading pipe 41 is constant, the pressure in the transverse sun shading pipe 42 and the longitudinal sun shading pipe 41 is changed because the water suction pump conveys the black solution inwards, therefore, the expansion degree of the greenhouse is changed to a certain extent, the section height of the black solution in the transverse sunshade tube 42 and the section height of the black solution in the longitudinal sunshade tube 41 are changed, the effect of the sunshade pipe network formed between the transverse sunshade tube 42 and the longitudinal sunshade tube 41 on absorbing external sunlight is changed, sunshade with different intensities is carried out on the greenhouse according to different external illumination intensities, the temperature in the greenhouse is always at the temperature suitable for growth of crops, and the condition that the temperature in the greenhouse is lower than the temperature suitable for growth and development of the crops in the environment with poor external illumination intensity due to the fact that the sunshade tubes completely shade the external sunlight is also avoided.
As an embodiment of the invention, a glass tube 21 is fixedly installed in the arch center 2, the glass tube 21 is positioned at the top end of the arch center 2, a black heat absorption film is plated outside the glass tube 21, and the glass tube 21 is communicated with an external water source;
during operation, because fixed mounting has glass pipe 21 in the bow member 2, and glass pipe 21 is located the 2 tops of bow member, consequently be in when hot house in winter under the environment that external light source intensity is not high, because glass pipe 21 has plated the black heat-absorbing film outward and can constantly absorb external solar energy medium heat radiation, draw external rivers suction into glass pipe 21 through the suction pump this moment in, and heat and keep warm through the rivers that the absorbed solar energy radiation of black heat-absorbing film flows in glass pipe 21, later control the rivers that store in the glass pipe 21 flow to the big-arch shelter once more in, heat up to the temperature in the big-arch shelter, thereby make the temperature keep in the big-arch shelter the temperature that crops grow and develop in the suitable big-arch shelter.
As an embodiment of the present invention, a U-shaped groove is formed in the top end of the arch frame 2, the glass tube 21 is located in the U-shaped groove, and the depth of the U-shaped groove is smaller than the radius of the glass tube 21;
the during operation, because the U-shaped groove has been seted up on 2 tops of bow member, and glass pipe 21 is located the U-shaped inslot, consequently glass pipe 21 receives the fixed in U-shaped groove in bow member 2, thereby can take place certain rocking along with bow member 2 together under the strong wind weather when having avoided glass pipe 21 direct mount to be inside in bow member 2, thereby lead to glass pipe 21 and bow member 2 to bump, lead to glass pipe 21 to take place to damage, unable work, and then influence the temperature cycle in the big-arch shelter, lead to the temperature in the big-arch shelter to be less than the suitable growing temperature of crops in the big-arch shelter when illumination intensity is not enough, make crops grow slowly.
As an embodiment of the present invention, the inner walls of the space where the liquid flows in the transverse sunshade tube 42 and the longitudinal sunshade tube 41 are coated with a hydrophobic coating;
when the shading tube works, when the black solution flows in the shading tube, as the hydrophobic coating made of the silicon dioxide nano material is directly introduced on the inner wall of the space of the flowing liquid in the shading tube, and the hydrophobic coating is uniformly contacted with the inner wall of the space of the flowing liquid in the sunshade tube and then is solidified on the inner wall to form a hydrophobic coating, so that the inner wall of the space for flowing liquid in the sunshade tube is uniformly coated with the hydrophobic coating made of the silicon dioxide nano particles, and therefore, when the black solution flows in the sunshade tube, the black solution cannot be adhered to the inner wall of the sunshade tube, thereby ensuring that the black solution can not be adhered to the inner wall of the sun-shading pipe when flowing in the sun-shading pipe, avoiding the black solution adhered to the inner wall of the sun-shading pipe when the illumination intensity in the greenhouse needs to be improved, therefore, the illumination intensity is insufficient, the temperature in the greenhouse cannot reach the proper temperature, and the growth and development of crops in the greenhouse are not facilitated.
The specific working process is as follows:
when the greenhouse is in an environment with high illumination intensity on fine days, the external sunlight directly irradiates on the greenhouse and irradiates on crops in the greenhouse through the plastic film 3, the temperature sensor is arranged in the greenhouse and detects the temperature in the greenhouse, when the temperature in the greenhouse is higher than the proper growth temperature of the crops, the temperature sensor transmits temperature information to the water pump, the black solution in the water storage tank flows into the transverse sun shielding pipe 42 and the longitudinal sun shielding pipe 41 by controlling the water pump, so that the sun shielding unit is changed from a transparent state to a black state, the light transmittance of the greenhouse is reduced, the illumination of the external sunlight which irradiates into the greenhouse is weakened, the temperature in the greenhouse is further reduced to the proper growth temperature of the crops, when the temperature in the greenhouse detected by the temperature sensor is lower than the proper growth temperature of the crops, the temperature sensor transmits information to the water pump, the water pump is controlled to stop working, no black solution is conveyed into the sun shading unit, at the moment, the black solution in the sun shading unit flows back into the water storage tank, meanwhile, the black solution in the sun shading unit absorbs enough heat under sufficient illumination, therefore, the black solution in the sun shading unit flowing back into the water storage tank releases certain heat in the water storage tank, and flows in the greenhouse through air, so that the temperature in the greenhouse is increased, the transverse sun shading pipe 42 and the longitudinal sun shading pipe 41 are both flat pipelines, at the moment, when the external sunlight intensity is too strong, as the sun shading pipe is flat, the area of a pipe network formed between the transverse sun shading pipe 42 and the longitudinal sun shading pipe 41 is increased, so that the shading area of the sun shading pipe to the external sunlight is larger, the shading effect is better, the sun shading pipe is provided with a cavity 43, and the cavity 43 is communicated with an external air conveying device, therefore, when the black solution is conveyed into the sun shading pipe by the water suction pump, the air is synchronously conveyed into the sun shading pipe by the external air conveying device, so that a closed heat insulation cavity is formed in the sun shading pipe, when the temperature in the greenhouse is higher than the external temperature under the regulation of the regulating device in the night environment, certain water drops are generated on the film 3 due to the difference between the internal temperature and the external temperature, at the moment, the grooves 411 are formed in the two sides of the longitudinal sun shading pipe 41, so that the water drops formed in the film 3 can be contacted with the grooves 411 on the two sides of the longitudinal sun shading pipe 41 when dropping downwards and flow out to the two sides along the longitudinal sun shading pipe 41 in the grooves 411, the depth of the grooves 411 is not more than the position of the cavity 43 in the sun shading pipe, so that the water flow collected in the grooves 411 is not contacted with the black solution layer flowing in the sun shading pipe, and the heat in the black solution flowing in the sun shading pipe is prevented from being absorbed when the water drops on the film 3 flow in the grooves 411, when the temperature in the greenhouse needs to be reduced, the black solution is pumped into the sun-shading pipe through the water suction pump, and the capacity of the water suction pump for conveying the black solution into the sun-shading pipe is controlled according to the change of the external illumination intensity, so that the volume of the solution in the sun-shading pipe changes, because the glass pipe 21 is fixedly arranged in the arch frame 2 and the glass pipe 21 is positioned at the top end of the arch frame 2, when the plastic greenhouse is in an environment with low external light source intensity in winter, the glass pipe 21 can continuously absorb heat radiation in external solar energy, heat the water flow in the pipe is heated and preserved through solar radiation, and then the water flow stored in the glass pipe 21 is controlled to flow into the greenhouse again to heat the temperature in the greenhouse, therefore, the temperature in the greenhouse is kept at the temperature suitable for the growth and development of crops in the greenhouse, the top end of the arch frame 2 is provided with the U-shaped groove, and the glass tube 21 is positioned in the U-shaped groove, so that the glass tube 21 is fixed in the arch frame 2 by the U-shaped groove, and when the black solution flows in the sun-shading tube, the black solution flowing in the inner wall of the sun-shading tube cannot be adhered to the inner wall of the sun-shading tube because the hydrophobic coating is coated on the inner wall of the sun-shading tube.
