Description

A kind of hardware thermal insulation solar greenhouse

technical field

The invention relates to the technical field of greenhouses, in particular to a hardware heat preservation solar greenhouse.

Background technique

The solar greenhouse is a type of crop cultivation facility used in northern my country. It mainly relies on sunlight to obtain energy to maintain a certain indoor temperature level to meet the needs of crop growth.

The traditional solar greenhouse adopts a special-shaped curved surface structure, and the insulation covering materials are soft materials such as straw curtains and cold-proof quilts. During the process of rolling and unwinding the curtains, the movement track of the rolling curtains has not been fixed, and it is difficult to achieve uniform thermal insulation materials in the solar greenhouse. , Accurate coverage in the light-transmitting area of the greenhouse has become one of the main obstacles to the automatic control and modernization of solar greenhouses in my country. At the same time, the external straw curtains, cold-proof quilts and other thermal insulation materials are not only poor in rain, snow, wind and fire protection. , and the use of multi-layer block covering method leads to poor sealing and unstable thermal insulation effect, which reduces the production performance of traditional solar greenhouses.

In order to solve the problems existing in the traditional solar greenhouse, a new type of solar greenhouse has been introduced on the market. See the patent with the publication number CN201938144U, and the name is "sliding-covered thermal insulation shed". The sliding-covered thermal insulation shed is an arc-shaped shed The outer surface of the arc-shaped shed is provided with an inner sliding layer covering the front light-transmitting film of the arc-shaped shed and an outer sliding layer covering the top of the shed. The inner sliding layer passes through the inner and outer slides and the pull rope And the rotating shaft drives the outer sliding layer to realize the opening and covering of the sliding insulation layer. By replacing soft materials such as straw curtains and cold-proof quilts with the sliding insulation layer, the opening and covering of the sliding insulation layer can be precisely controlled and automated as long as it slides on the shed body.

However, the skeleton of the sliding covered insulation shed is composed of multiple trusses, and each truss is composed of a dynamic truss and a supporting truss. Since there is sliding friction between each truss and the sliding insulation layer, the total sliding friction of the entire skeleton is large, the noise is large, the power consumption is large, the wear is serious, and maintenance is inconvenient, which increases the operating cost. In addition, the rotating shaft is suspended on the inverted triangular steel structure, and the steel wire rope directly passes through the film from the upper part of the greenhouse to the track of the skeleton. Due to the heavy weight of the covering parts, the supporting steel structure and the rotating shaft of this design are prone to deformation, and the steel truss structure is not stable. At the same time, there are insurmountable air and rain leakages at the part where the wire ropes pass through the top of the greenhouse.

To sum up, how to reduce the operating noise, wear and power consumption of the solar greenhouse and reduce the operating cost under the premise of uniform and accurate covering and opening of the covering materials of the solar greenhouse, and at the same time, simplify the greenhouse skeleton structure and improve the solar greenhouse skeleton The speed of processing and installation and the reduction of greenhouse construction cost have become problems to be solved urgently by those skilled in the art.

In the above-mentioned hardware thermal insulation solar greenhouse, the sliding drive system drives the sliding of the hardware thermal insulation components on the frame 7 to realize the shading and light transmission, heat storage and heat preservation of the solar greenhouse, and achieve the basic functions of the solar greenhouse. Since the hard heat insulation component is a hard structure, and can slide on the skeleton 7 through the cooperation of the first slideway 101 and the second slideway, it can achieve more uniform heat preservation compared with existing soft heat preservation materials such as straw curtains. and more accurate coverage, improve the thermal insulation performance, and realize the automatic control of shading and light transmission in the solar greenhouse. At the same time, the main truss 1 and the auxiliary truss 2 are separate structures, and multiple adjacent main trusses 1 are arranged. The auxiliary truss 2 is composed of the main truss 1 and the auxiliary truss 2 to form the skeleton 7. Compared with the existing integrated structure of the dynamic truss and the supporting truss, the main truss is greatly reduced under the premise of ensuring sufficient bearing capacity. The number of 1 used simplifies the structure of the greenhouse skeleton and significantly reduces the construction cost of the greenhouse. At the same time, it also greatly reduces the friction contact between the skeleton 7 and the hardware insulation components, thereby reducing noise, power consumption and wear , only the main truss 1 needs to be repaired and replaced, the maintenance is convenient and the operating cost is reduced.

As shown in FIGS. 1-4 , this embodiment provides a solar greenhouse with hardware heat preservation, wherein the hardware heat preservation component includes a fixed hardware heat preservation component 3 and a sliding hardware heat preservation component 4 . The arc-shaped structure of the fixed hardware heat preservation part 3 matches the skeleton 7, and is fixed on the backlight side of the skeleton 7 (the working position of the hardware heat preservation solar greenhouse in this embodiment is to sit north and face south, and the backlight side is the north of the skeleton 7. side, the light-facing side is the south side of the framework 7, for the convenience of description, the position is limited by the south side and the north side in the text), and cannot slide; the inner side of the sliding hardware insulation component 4 and the fixed hardware insulation component The outer shape is consistent, and the whole is also an arc-shaped structure. There is a second slideway that is slidably matched with the first slideway 101. The sliding drive system is connected with the sliding hardware heat preservation component. Sliding on the truss, through the sliding of the sliding hardware insulation components, the opening and covering of the greenhouse are realized for light transmission and shading, heat storage and heat preservation.

As shown in Figure 3 and Figure 4, in this implementation, a specific sliding drive system is provided, which is located on the outside of the skeleton 7, including a first drive rod 10, a second drive rod 11 and a telescopic drive 12; wherein, The outer surface of the sliding hardware heat preservation component 4 is provided with a drive rod slideway 9, and one end of the first drive rod 10 is slidingly connected with the drive rod slideway 9, and the first drive rod 10 can drive the sliding hardware heat preservation component 4 on the main truss 1 Sliding up; the second driving rod 11 is hinged with the first driving rod 10, and one end of the second driving rod 11 away from the hinge point is hinged and fixed; the two ends of the telescopic driver 12 are respectively connected with the first driving rod 10 and the second driving rod 11, For driving the relative rotation of the first driving rod 10 and the second driving rod 11, the telescopic driver 12 can be a hydraulic driver or a pneumatic driver. turn.

The working principle and working process of the hardware thermal insulation solar greenhouse with the above-mentioned sliding drive system are as follows: Referring to Figure 3 and Figure 4, when the sliding hardware thermal insulation component 4 covers the south side of the frame 7, that is, when the solar greenhouse is opaque, Telescopic driver 12 is in stretched state, and its state is as shown in Figure 3, if will open sliding hardware insulation assembly 4, when carrying out the light transmission of solar greenhouse, start telescopic driver 12, telescopic driver 12 shrinks, because the second driving rod 11 One end of the hinge is fixed, the first driving rod 10 rotates relative to the second driving rod 11 around the point hinged with the second driving rod 11, and the first driving rod 10 rotates around the fixed hinged end, and in the process, the first driving rod One end of 10 pulls the sliding hardware heat preservation component 4 to slide toward the north side of the skeleton 7. When the center of the sliding hardware heat preservation component 4 moves to the north-south middle position of the skeleton 7, due to the gravity of the sliding hardware heat preservation component 4, the sliding hardware The heat preservation component 4 continues to move downward, at this moment, the sliding connection end of the first drive rod 10 can slowly move from point A to point B along the drive rod slideway 9, and at the same time, the stable operation of the sliding hardware heat preservation component 4 can be ensured . When it is necessary to close the sliding hardware thermal insulation assembly 4, that is, when the solar greenhouse is shaded, the telescopic driver 12 is extended and the opposite movement to the above can be realized.

Due to the adoption of the external sliding drive system, compared with the existing drive device arranged inside the greenhouse and suspended on the top of the greenhouse, the sliding drive system of the present invention will not generate loads on the skeleton 7, thereby reducing the skeleton The load of 7 ensures the structural stability of the skeleton 7, and compared with the existing steel wire rope directly passing through the film from the upper part of the greenhouse to the track of the skeleton 7, which causes insurmountable air leakage and rain leakage on the top of the greenhouse, this The invented sliding drive system does not cause air leakage and rain leakage in the greenhouse, thereby ensuring the thermal insulation performance and working reliability of the greenhouse, and reducing maintenance costs.

When the sliding hardware thermal insulation assembly 4 is covered on the skeleton 7, the inner layer thermal insulation part 402 is located at the southernmost side of the skeleton 7, and the outer layer thermal insulation part 401 is located in the middle of the skeleton 7; when the sliding hardware thermal insulation assembly 4 needs to be opened, Pull the outer heat preservation part 401 to move to the north side through the sliding drive system, and the outer heat preservation part 401 pulls the inner heat preservation part 402 to move to the north side of the skeleton. When the outer heat preservation part 401 slides to the northernmost side of the skeleton 7, the inner layer The thermal insulation part 402 slides to the northernmost side of the skeleton 7 under the action of its own gravity. At this time, the outer layer thermal insulation part 401, the inner layer thermal insulation part 402 and the fixed hardware thermal insulation part 3 overlap and are located on the north side of the skeleton 7, so that the sliding The hardware heat preservation assembly 4 is fully opened, as shown in FIG. 6 . When closing the sliding hardware heat preservation assembly 4, it can be completed by making the sliding drive system run in reverse.

Further, in this embodiment, as shown in Fig. 5 and Fig. 6, the inner layer insulation 402, the outer layer insulation 401 and the fixed hardware insulation 3 can respectively cover one-third of the arc section of the skeleton 7, then When the sliding hardware thermal insulation assembly 4 is fully opened, 2/3 of the area of the solar greenhouse can be light-transmitting, and this three-stage thermal insulation structure can meet the requirements of crops with relatively high light requirements. Of course, the coverage ratios of the inner layer thermal insulation 402, the outer layer thermal insulation 401 and the fixed hardware thermal insulation 3 can take other values, as long as the requirements of the crops for light can be met.

As shown in Figures 7 to 10, the embodiment of the present invention provides a third type of hardware heat preservation solar greenhouse. The thermal insulation part and several outer sliding thermal insulation parts, each inner sliding thermal insulation part is slidingly connected with the main truss 1; the outer layer sliding thermal insulation part is slidingly connected to the outside of the inner layer sliding thermal insulation part, and the outer layer sliding thermal insulation part can be slid with the inner layer for thermal insulation The number of parts is the same, and one to one correspondence, also can be different in number, the number of outer layer sliding heat preservation parts is smaller than the number of inner layer sliding heat preservation parts. The hardware thermal insulation component can also be of multi-layer structure, as long as it can slide mutually to realize covering and opening of the greenhouse.

This design has completely changed the traditional building structure and characteristics of the solar greenhouse in my country, which is facing south and east-west. Therefore, it is possible to build a multi-stage hard-insulated solar greenhouse in any direction, so that the construction of the solar greenhouse is not restricted by the location of the land. , significantly improving land use efficiency.

The outer side of the first layer sliding thermal insulation 14, meanwhile, the second inner sliding thermal insulation 15 and the second outer sliding thermal insulation 17 slide to the west side of the skeleton 7, and sunlight shines into the greenhouse from the east side of the greenhouse; at noon, the second Inner sliding thermal insulation 15 and second outer sliding thermal insulation 17 slide to the east side of skeleton 7, and second outer sliding thermal insulation 17 covers the outer side of second inner sliding thermal insulation 15. At this time, the sunlight from the greenhouse In the afternoon, the first inner sliding thermal insulation 14 and the first outer sliding thermal insulation 16 slide to the east side of the frame 7, and the first outer sliding thermal insulation 16 covers the first inner sliding Insulation part 14 outside, at this moment, sunlight shines into the interior of the greenhouse from the west side of the greenhouse; at night, the first inner layer sliding insulation part 14 and the first outer layer sliding insulation part 16 slide to the west side of the skeleton 7, and the first Outer layer sliding insulation part 16 is launched from the first inner layer sliding insulation part 14, and the second outer layer sliding insulation part 17 is launched from the second inner layer sliding insulation part 15, so that the second outer layer sliding insulation part 17 and the first The outer layer sliding thermal insulation member 16 is positioned on the top of the greenhouse, thereby completely covering the greenhouse to realize shading and heat preservation of the greenhouse. Similarly, if it is a five-stage, six-stage or more hard insulation structure, as the sun moves from east to west in the morning, each section of hard insulation can gradually slide from west to east until all the hard insulation The thermal insulation slides to the east side of the greenhouse to meet the needs of crop growth for light. At night, the hard thermal insulation on the west side returns to achieve full shading and thermal insulation coverage. Among them, there are many transmission structures of each segment of the hardware heat preservation part, and the patent documents with publication numbers CN203661717U and CN203523431U can be referred to, and no specific introduction and limitation are made here.

In order to improve the light transmittance, the light-transmitting film 6 preferably adopts a single-layer light-transmitting film, and the light transmittance reaches more than 85%. , which can solve the problem that the fixed gable wall affects the growth of crops due to shading.

The working process of the above-mentioned gable 5 is: as shown in Figure 7 and Figure 8, in the morning, the moving gable 502 located on the east side of the solar greenhouse is moved to the north side of the frame 7, and the morning light enters the interior of the greenhouse through the light-transmitting film 6 on the east side of the frame 7 , compared with the existing non-movable gables, the utilization rate of daylight is greatly improved. After noon, the moving gable 502 on the east side is moved back to the south side of the skeleton 7, and the gable 502 on the east side is closed for heat preservation. At the same time, the The moving gable 502 on the west side of the solar greenhouse moves to the north side of the skeleton 7, and the sunlight in the afternoon enters the interior of the greenhouse through the light-transmitting film 6 on the west side of the skeleton, making full use of the sunlight. Moreover, compared with the simple gable without shading, the movable gable can not only effectively insulate, but also fully irradiate the sun, ensure the temperature balance of the greenhouse, and ensure the normal growth of crops at both ends of the east and west gables in the greenhouse.

After the control system receives the indoor and outdoor temperature information, it compares it with the preset set temperature value. When the outdoor temperature is higher than the set temperature value, the control system controls the driving device to drive the moving gable 502 on the east side to move from the south side to the north side; or the daylight sensor detects the sunshine intensity, sends the sunshine intensity information to the control system, and the control system accepts After the sunlight intensity information, it is compared with the preset sunlight intensity value, and when the sunlight intensity is higher than the preset sunlight intensity value, the control system controls the driving device to drive the east side moving gable 502 to move from the south side to the north side; or when When the indoor and outdoor temperature and sunlight intensity both reach the preset value, the control system controls the driving device to act.

When the indoor and outdoor temperature and/or sunlight intensity is lower than the preset value, the control system controls the driving device to drive the moving gable 502 on the east side to return to the south side. The motion of the gable wall 502 on the west side is the same as that on the east side, and will not be repeated here.

Wherein, the set temperature value and the set sunlight intensity value are adjusted according to different regions and seasons, and are not specifically limited here.

Preferably, the driving device includes a driving motor 8, a driving belt and a guide rail, and the moving gable 502 moves along the guide rail under the driving and transmission of the driving motor 8 and the driving belt, so as to realize opening and closing of the moving gable 502.

In the embodiment of the present invention, the fixed hardware thermal insulation component 3, the sliding hardware thermal insulation component 4 and the gable wall 5 are all composed of a frame, a waterproof layer, a thermal insulation layer and a long-wave radiation layer: the frame is made of light steel to ensure its hardness. and structural strength, the waterproof layer, heat insulation layer and long-wave radiation layer are arranged in the frame from outside to inside in sequence. The length of the frame is the same as the length of the greenhouse. It is made of light steel materials such as steel pipes and steel bars. The thickness of the frame is determined according to the thickness of the heat insulation material required for the lowest temperature in each place; the waterproof layer is mainly made of color steel plate, sunshine board, endurance board, glass steel board, or asbestos board and other hard materials with rainproof, snowproof, fireproof and windproof functions; the heat insulation layer filled inside is mainly composed of rock wool, glass wool, flame-retardant benzene board, spray glued cotton, hot-melt cotton, Or cotton felt and other materials; the lower long-wave radiation layer is mainly composed of tinfoil, reflective film, etc. Compared with soft covering materials such as straw curtains and cold-proof quilts, the thermal insulation performance and the ability to resist natural disasters are greatly enhanced.
