Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic greenhouses for growing vegetables and fruits, namely a greenhouse with a heat preservation and shade screen. The temperature in the greenhouse is maintained in winter, and it has a shade function in summer, which can effectively adjust the summer temperature. Background Art
[0002] In the prior art, fruit thinning plastic greenhouses are more suitable for off-season planting in the north, and can be used to grow vegetables and fruits. Most greenhouses in the Northeast are mainly steel structures, and quilts are used to wrap the outside of the steel structure for insulation. However, the Northeast has a high latitude and low temperatures in winter, so the insulation effect of a single-layer insulation quilt in the Northeast is not very ideal. Most greenhouses need to add heating facilities to increase the temperature inside the greenhouse. In order to maintain the temperature inside the greenhouse, there are currently double-layer steel frames and double-layer quilts. However, the double-layer steel frame and double-layer quilt increase the cost of the greenhouse, and a layer of quilt inside the greenhouse also blocks most of the light, so there is a situation where insufficient light leads to poor growth of crops, and because the double-layer frame structure also leads to a reduction in the original planting area. At present, the heating of fruit thinning plastic greenhouses is to use the sun-facing plastic shed surface for lighting and heating, and the second is to set a heating furnace in the shed for heating. The disadvantages are waste of fuel energy, uneven heating, and environmental pollution. Utility Model Content
[0003] The utility model aims to provide a greenhouse with a heat preservation and shade screen, which can improve the heat preservation and shade effect, save energy and clean the environment, in view of the above-mentioned shortcomings.
[0004] The technical solution of the utility model is: a greenhouse with a heat-insulating shade screen, comprising a shed body, characterized in that an integral heat-insulating shade screen is laid flat in the air inside the shed body, and the integral heat-insulating shade screen is provided with folds at intervals along the width direction of the shed body; the rear end of the integral heat-insulating shade screen is fixed to the shed body, and the front end of the integral heat-insulating shade screen is connected to a traction rope that can be pulled backward, a plurality of traction ropes are arranged at intervals along the length direction of the shed body, and the rear end of each traction rope is connected to a traction motor through a left pulley; a plurality of lifting ropes with both ends fixed are provided under the integral heat-insulating shade screen.
[0005] The above scheme also includes:
[0006] Both ends of the traction motor are connected to a long output shaft, and the corresponding traction ropes on the long output shaft are equipped with multiple rope winders. After each traction rope is connected to the rope winder, it is pulled out to bypass the guide pulley under the integral thermal insulation shade screen and is connected to the right pulley opposite the shed body, and finally connected to the traction rope at the front end of the integral thermal insulation shade screen.
[0007] There is an acrylic plate under the right pulley.
[0008] The lifting ropes are stretched along the width direction of the shed body and arranged at intervals along the length direction.
[0009] The integral heat-insulating shade screen is set in the middle of the air of the shed or at a height of 2-2.5 meters from the ground.
[0010] An inclined integral thermal insulation shade screen is arranged between the lower part of the integral thermal insulation shade screen on the front slope of the shed body and the bottom of the shed, and the inclined integral thermal insulation shade screen is provided with folds at intervals along the direction of the bottom of the shed; the lower end of the inclined integral thermal insulation shade screen is fixed to the shed body, and the upper end of the inclined integral thermal insulation shade screen is connected to a second traction rope that can be pulled downward, and a plurality of second traction ropes are arranged at intervals along the length direction of the shed body, and the lower end of each second traction rope is connected to the second traction motor through a lower pulley.
[0011] Another long output shaft is connected at both ends of the second traction motor, and the long output shaft is equipped with multiple second rope winders. After each second traction rope is connected to the second rope winder, it is pulled out to bypass the second guide pulley under the inclined integral thermal insulation shade screen and the upper pulley on the inclined integral thermal insulation shade screen, and finally connected to the second traction rope at the front end of the inclined integral thermal insulation shade screen.
[0012] The advantages of the utility model are as follows: 1. An integral heat-insulating shade screen is laid flat in the air in the greenhouse, and an integral heat-insulating shade screen is laid obliquely in the lower front part of the greenhouse. In winter, the interior of the greenhouse is insulated twice, and the heat stored during the day is effectively maintained to maintain the temperature inside the greenhouse. In summer, the temperature inside the greenhouse can be adjusted by shading. In the absence of heating facilities in the greenhouse, the average temperature in the greenhouse reaches 10°C in winter (excluding very few continuous cloudy days or extremely cold weather), which not only meets the needs of fruit thinning growth, but also does not require heating facilities to be installed in the greenhouse in winter, which is energy-saving and environmentally friendly. 2. The integral heat-insulating shade screen is used, which is laid without gaps, and the heat-insulating shade is better. 3. The integral heat-insulating shade screen has a folding structure, which does not take up space, does not block light, is conducive to fruit thinning and light, and increases yield.

[0021] See also Figure 1 -7, the names of the parts are as follows: integral thermal insulation shade screen 1, fold 2, traction rope 3, left pulley 4, traction motor 5, lifting rope 6, shed body 7, rope reel 8, guide pulley 9, right pulley 10, acrylic plate 11, inclined integral thermal insulation shade screen 12, second traction rope 13, lower pulley 14, second traction motor 15, front slope 16, second rope reel 17, second guide pulley 18, upper pulley 19, cold-proof blanket 20, long output shaft 21.
[0022] See also Figure 1 -7, the greenhouse with heat preservation and shade screen is mainly composed of steel frame shed 7, with plastic shed film and roll-up cold-proof blanket 20 on the outer shed surface of shed 7. The right side of shed 7 is the front, which is the sunny side, and the left side of shed 7 is the back. There is a door on one end of shed 7 (omitted in the figure). The length and width of shed 7 are 130×14 meters, the length of shed is L, and the width of shed is L1 (see Figure 7 ).
[0023] The air in the shed 7 is also paved with an additional integral heat-insulating and shade-shielding screen 1 ( Figure 1 The screen is pulled to the left to show the folded state). The front of the shed 7 at the lower part of the integral heat-insulating shade screen 1 is obliquely laid with an integral heat-insulating shade screen 12. Under the action of the traction rope 3 (plastic-coated steel strand), the left pulley 4, the traction motor 5, the reducer, the guide pulley 9, and the right pulley 10, the integral heat-insulating shade screen 1 can be pulled to the left (back) and folded when not in use, without blocking light; when heat preservation and sunshade are needed, the whole is stretched flat and spread out. Similarly (see Figure 1 , 3 4) The inclined integral heat-insulating shade screen 12 can be pulled downward and folded when not in use under the action of the second traction rope 13, the lower pulley 14, the second traction motor 15, the reducer, the second guide pulley 18 and the upper pulley 19, so as not to block light; when heat preservation and sunshade are needed, the whole is pulled up and spread out obliquely to connect with the integral heat-insulating shade screen 1 to achieve full coverage.
[0024] Specifically: See Figure 1 , 25. The greenhouse with heat preservation and shade screen has an integral heat preservation and shade screen 1 laid flat in the air inside the shed 7. The integral heat preservation and shade screen 1 is a whole piece, which covers the length and width of the shed 7 as a whole, and has better heat preservation and shade screen effects. The integral heat preservation and shade screen 1 is provided with folds 2 at intervals along the width direction of the shed 7. The integral heat preservation and shade screen 1 is set in the middle of the air of the shed 7 or at a height of 2-2.5 meters from the ground. The integral heat preservation and shade screen 1 is made of EPE cloth (ethylene-vinyl acetate copolymer foam cotton), 2cm thick, with fold intervals of 15cm. For the integral heat preservation and shade screen 1 with a width of 11.45m, it is within 1 meter after folding backwards, so that the structure is compact and does not block light after folding. The rear end of the integral thermal insulation shade screen 1 is fixed to the shed body 7, and the front end of the integral thermal insulation shade screen 1 is connected to a traction rope 3 that can be pulled backward. A plurality of traction ropes 3 are arranged at intervals along the length direction of the shed body 7, such as one at an interval of 3 meters. The rear end of each traction rope 3 is connected to the traction motor 5 through the left pulley 4; there are a plurality of lifting ropes 6 (plastic steel wires) with both ends fixed under the integral thermal insulation shade screen 1. The lifting ropes 6 are stretched along the width direction of the shed body 7 and are arranged at intervals along the length direction.
[0025] A traction motor 5 is connected to a long output shaft 21 at both ends. The long output shaft 21 is arranged along the length direction of the shed body 7, and there are spaced supports on it. The long output shaft 21 is provided with multiple rope reels 8 (drums) corresponding to the traction rope 3. After each traction rope 3 is connected to the rope reel 8, it is pulled out to bypass the guide pulley 9 under the integral heat preservation shade screen 1 and is wound around the right pulley 10 opposite the shed body 7, and finally connected to the traction rope 3 at the front end of the integral heat preservation shade screen 1. The right pulley 10 is in contact with an acrylic plate 11 below, which supports multiple right pulleys 10 on the same plane. The acrylic plate 11 is transparent and does not block light, and connects the integral heat preservation shade screen 1 and the inclined integral heat preservation shade screen 12. The traction motor 5 rotates forward, and at the same time drives multiple traction ropes 3 to pull the integral heat preservation shade screen 1 backward at the same time, and finally folds it within a range of one meter. Conversely, the traction motor 5 reverses, and at the same time drives multiple traction ropes 3 to pull the integral heat preservation shade screen 1 forward at the same time, so as to achieve flat laying.
[0026] See also Figure 1 , 3 4. An inclined integral thermal insulation shade screen 12 is arranged between the lower part of the integral thermal insulation shade screen 1 on the front slope surface 16 inside the shed body 7 and the bottom of the shed. The inclined integral thermal insulation shade screen 12 is provided with folds at intervals along the direction of the bottom of the shed; the lower end of the inclined integral thermal insulation shade screen 12 is fixed to the shed body 7, and the upper end of the inclined integral thermal insulation shade screen 12 is connected to a second traction rope 13 that can be pulled downward. A plurality of second traction ropes 13 are arranged at intervals along the length direction of the shed body 7, and the lower end of each second traction rope 13 is connected to a second traction motor 15 through a lower pulley 14.
[0027] A second traction motor 15 is connected at both ends to another long output shaft, and the long output shaft is provided with multiple second rope winders 17. After each second traction rope 13 is connected to the second rope winder 17, it is pulled out to pass around the second guide pulley 18 under the inclined integral thermal insulation shade screen 12 and the upper pulley 19 on the inclined integral thermal insulation shade screen 12, and finally connected to the second traction rope 13 at the front end of the inclined integral thermal insulation shade screen 12.
[0028] See also Figure 1 , 3 7. There are 50 cm wide translucent acrylic plates 11 at the junction of the integral thermal insulation shade screen 1 and the inclined integral thermal insulation shade screen 12 and at the gable of the greenhouse. They can be sealed when overlapped to improve the thermal insulation effect and can achieve the effect of not blocking sunlight when the thermal insulation shade screen is not in use.
[0029] The traction motor 5 and the second traction motor 15 can be intelligently controlled, and can automatically open and close the integral heat-insulating shade screen 1 and the inclined integral heat-insulating shade screen 12 according to the internal temperature of the greenhouse body 7, so as to ensure that the internal temperature of the greenhouse maintains the optimal temperature for plant growth, but is not limited to this.
