Description

Technical Field

[0001] This invention relates to the field of solar energy utilization equipment technology, specifically to a suspended grid structure solar vacuum collector matrix. Background Technology

[0002] In the fields of industry, agriculture, and animal husbandry, a large amount of low-temperature heat sources of 10-30℃ are required. There is a conflict between the space occupied by heat energy collection and building structures. Solar tubes are mature and inexpensive, and their availability depends on the area and quantity. Traditional solar vacuum collectors are limited by their installation methods and are mostly fixed on building roofs, making them unsuitable for large-span facilities such as vegetable greenhouses and biogas digesters. At the same time, agricultural and animal husbandry production often requires maintaining an ambient temperature of 10-35℃. In the traditional mode, external energy is needed for temperature and humidity regulation, which increases energy consumption and costs. Existing traditional solar vacuum collectors are installed on roofs, but they cannot be installed on large-span buildings such as vegetable greenhouses (glass houses) and biogas digesters, and external energy is needed to increase or decrease temperature and humidity. If installed directly on the ground or at low altitude, they will block natural sunlight and affect production and life below. If traditional brackets are used for high-altitude installation, there are problems such as complex structure, high cost, and difficult installation. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a suspended cable-stayed grid structure solar vacuum collector matrix to solve the problems mentioned in the background. The invention features a novel structure, utilizing a lattice frame structure built with steel strands and columns. This structure eliminates the need for building roofs or traditional supports, allowing direct installation above large-span facilities such as vegetable greenhouses and biogas digesters. The clearance height of over 6.5m avoids obstructing ground-level facilities and solves the technical pain point of traditional collectors being unable to adapt to large-span scenarios. It also meets the environmental temperature requirements of agriculture and animal husbandry (10-35℃) and can be seamlessly integrated with heat-using equipment such as biogas production and greenhouse cultivation. Its application scope covers multiple fields including agriculture, animal husbandry, and building energy conservation.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a suspended grid structure solar vacuum collector matrix, comprising columns, grid crossbars, steel strands, a collector net, collector tube seats, and a suspended basket. The columns on both sides are symmetrically and vertically installed on the ground. The grid crossbars on both sides are fixedly connected to the tops of the columns on both sides, connecting the columns on both sides into a whole. The sides of the columns are fixedly connected with inclined guy wires to enhance their stability. The collector net is suspended on the steel strands and arranged in series along the length of the steel strands. The collector tube seats are hung on the steel strands. The suspended basket is assembled on the steel strands. The interior of the suspended basket is equipped with a pulley mechanism and a motor drive mechanism.

[0005] Furthermore, one of the left and right columns is more than 100cm higher than the other, the clear distance between the top of the column 1 and the top of the ground object is greater than 6.5m, one end of the diagonal guy wire is fixedly connected to the side of the column, and the other end is anchored to a fixed foundation preset on the ground, and the diagonal guy wire, the column and the ground form a stable triangular support structure.

[0006] Furthermore, mounting positions are symmetrically and evenly distributed on the crossbars of the space frame on both sides, with a spacing of 10-50cm between two adjacent mounting positions. The two ends of the steel strand are installed on the mounting positions of the crossbars of the space frame on the left and right sides to form a radial support structure. A tensioning mechanism is provided between one end of the steel strand and the mounting position of one side of the space frame crossbar, and the other end is fixedly connected to the mounting position of the corresponding side of the space frame crossbar. The tensioning mechanism includes a screw fixedly connected to the mounting position on one side of the space frame crossbar and one end of the steel strand. An adjusting sleeve is provided between the two screws, and the two ends of the adjusting sleeve are threadedly engaged with the two screws respectively.

[0007] Furthermore, the solar collector network is formed by assembling solar vacuum collector tubes, with a distance of 5-15cm between the ends of two adjacent solar vacuum collector tubes, and connecting buckles that are snapped onto steel strands are fixedly connected to the upper sides of both ends of the solar vacuum collector tubes.

[0008] Furthermore, the heat collection network 4 is formed by a continuous heat collection pipeline combination.

[0009] Furthermore, the upper side of the heat collector tube base is fixedly connected with multiple evenly distributed mounting brackets, which are hung on the steel strand. The heat collector tube base and the steel strand are arranged perpendicularly in the horizontal direction, and the heat collector tube base is provided with a positioning groove that matches the end of the solar vacuum heat collector tube.

[0010] Furthermore, a heat-conducting pipe is fixedly connected inside the heat collector tube seat. The circulation pipeline of the heat-conducting pipe on the heat collector tube seat and the heat insulation shell form a latitudinal structure. The latitudinal structure and the warp steel strands together form a warp and weft grid structure. The heat-conducting pipe is made of corrosion-resistant and high-temperature resistant pipe material.

[0011] Furthermore, the steel strand is made of high-strength material. One end of the steel strand is fixedly connected to the installation position of the crossbar of the space frame, and the other end is fixedly connected to the installation position of the corresponding side crossbar of the space frame. The tension of the steel strand is adjusted by tooling and then tightened and locked.

[0012] Furthermore, the diameter of the solar vacuum collector tube is 47mm or more, and the net space distance between the bottom of the solar vacuum collector tube and the top of the ground object is greater than 6.5m.

[0013] Furthermore, the suspended platform is provided in multiple sets, and multiple sets of suspended platforms can be installed simultaneously in different sections of steel strand. The motor drive mechanism is equipped with a wireless control module, which can remotely control the direction of movement, speed of movement, and start / stop status of the suspended platform.

[0014] Furthermore, a method for installing a suspended grid structure solar vacuum collector matrix includes the following steps:

[0015] S1: Foundation construction and column fixing: Determine the specifications of the columns according to the height of the ground objects, ensure that the height difference between the left and right columns is not less than 100cm, mark the symmetrical installation positions and pre-embed anchor bolts; vertically hoist and fix the columns, and ensure vertical stability by tightening the anchor bolts.

[0016] S2: Support structure assembly: Install diagonal tie rods, with one end fixed to the side of the column and the other end anchored to the ground to form a triangular support; hoist the crossbars of the space frame to the top of the column and fix them, ensuring that the installation positions of the crossbars on both sides of the space frame are symmetrical, so that the columns are connected into an integral frame;

[0017] S3: Warp strand erection: Install the two ends of the high-strength steel strands on the installation positions of the crossbars on both sides of the grid. One end is tensioned and installed with the crossbar of the grid through a tensioning mechanism. The tensioning can be adjusted and locked to form a warp support structure, thus completing the installation of all steel strands.

[0018] S4: Installation of auxiliary and fixed components: Assemble multiple sets of suspended baskets to the steel strand, and debug the wirelessly controlled motor drive and pulley mechanism to ensure flexible movement; hang the heat collector tube base on the steel strand via the hanging frame through the suspended basket, keeping it perpendicular to the steel strand;

[0019] S5: The solar vacuum collector tubes are hoisted using a basket, and the steel strands are connected with connecting clips and embedded into the positioning grooves of the collector tube base. They are then installed in series with a 5-15cm end-to-end spacing to ensure a clearance distance of more than 6.5m. The heat-conducting pipes are connected to form a circulation pipeline, and the heat-insulating shell is wrapped to form a latitudinal structure, which together with the warp steel strands forms a warp and weft grid.

[0020] S6: Overall commissioning and acceptance: Check the stability and installation accuracy of each component, and test the operational flexibility using a suspended platform; start the system for trial operation to verify the heat collection and heat transfer effects, and complete the installation after confirming that there are no abnormalities.

[0021] The beneficial effects of this invention are:

[0022] 1. This type of suspended grid structure solar vacuum collector matrix adopts a high-altitude flexible suspension design. The warp and weft grid structure constructed by steel strands and columns does not rely on building roofs or traditional supports. It can be directly erected above large-span facilities such as vegetable greenhouses and biogas digesters. The clear height of more than 6.5m not only avoids obstructing ground facilities, but also solves the technical pain point that traditional collectors cannot adapt to large-span scenarios. At the same time, it is suitable for the environmental temperature requirements of agriculture and animal husbandry of 10-35℃. It can be seamlessly connected with heat-using equipment such as biogas production and greenhouse planting. Its application scope covers multiple fields such as agriculture, animal husbandry, and building energy conservation.

[0023] 2. This suspended cable-stayed grid structure solar vacuum collector matrix suspends the collectors at high altitudes, without occupying ground-level production space. Below, normal production and living activities such as greenhouse cultivation, biogas digester maintenance, and agricultural machinery passage are possible, achieving the dual value of "aerial heat collection and ground utilization." Simultaneously, the reasonable clearance between the collector pipes and the ground ensures that natural ground lighting is not affected, making it particularly suitable for scenarios with high light requirements, such as vegetable greenhouses, guaranteeing crop photosynthesis and normal production processes, and solving the problem of traditional low-altitude collector installations blocking sunlight.

[0024] 3. This suspended grid structure solar vacuum collector matrix, through the height difference design of the two side columns and the linear series arrangement of the collector tubes, ensures that the collector network is always at the optimal light-receiving angle. Combined with mature vacuum collector technology, it ensures stable heat energy collection efficiency. The heat-conducting pipe's heat-insulating shell design reduces heat loss and improves heat energy utilization. In addition, this collector does not rely on external energy for temperature and humidity regulation and can directly provide stable heat energy to ground facilities, reducing the energy consumption cost of traditional heating and cooling methods and meeting the requirements of energy conservation and emission reduction.

[0025] 4. This type of suspended grid structure solar vacuum collector matrix fixes the columns to the ground with pre-embedded anchor bolts, and the triangular support structure formed by the inclined wires enhances the overall wind load resistance and overturning resistance. The steel strands are made of high-strength materials, and the precise matching of the collector tube seat and the collector tube, as well as the corrosion-resistant and high-temperature-resistant design of the heat conduction tube, all improve the stability and durability of the structure. It can adapt to long-term outdoor operation environment and extend the service life of the equipment. At the same time, the flexible mobility of the suspended platform provides convenience for later maintenance and reduces operation and maintenance costs and safety risks. Attached Figure Description

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] Please refer to Figures 1 to 7This invention provides a technical solution: a suspended grid structure solar vacuum collector matrix, including columns 1, grid crossbars 2, steel strands 3, collector nets 4, collector tube seats 5, and a suspended basket 6. The columns 1 on both sides are symmetrically and vertically installed on the ground. The grid crossbars 2 on both sides are respectively fixedly connected to the top of the columns 1 on both sides, connecting the columns 1 on both sides into a whole. The sides of the columns 1 are fixedly connected with inclined wires 7 to enhance their stability. The collector nets 4 are suspended on the steel strands 3 and arranged in series along the length of the steel strands 3. The collector tube seats 5 are hung on the steel strands 3. A heat-conducting pipe 8 is fixedly connected inside the collector tube seats 5. The suspended basket 6 is assembled on the steel strands 3. The interior of the suspended basket 6 is provided with a pulley mechanism 61 and a motor drive mechanism 62.

[0040] In this embodiment, one of the left and right columns 1 is more than 100cm higher than the other. The clear distance between the top of the column 1 and the top of the ground object is greater than 6.5m. The bottom of the column 1 is fixedly connected to the ground by pre-embedded anchor bolts to ensure the vertical stability of the column 1. The horizontal bars 2 on both sides of the space frame have symmetrically and evenly distributed installation positions 21, with a spacing of 10-50cm between two adjacent installation positions 21. The two ends of the steel strand 3 are installed on the installation positions 21 of the horizontal bars 2 on the left and right sides to form a radial support structure. A tensioning mechanism 9 is provided between one end of the steel strand 3 and the installation position 21 of one side of the space frame horizontal bar 2, and the other end is fixedly connected to the installation position 21 of the corresponding side of the space frame horizontal bar 2. The tensioning mechanism 9 includes... The system includes a screw 91 fixedly connected to a mounting position 21 on a crossbar 2 of a grid frame on one side and one end of a steel strand 3. An adjusting sleeve 92 is provided between the two screws 91, and the two ends of the adjusting sleeve 92 are threadedly engaged with the two screws 91 respectively. The heat collection network 4 is formed by assembling solar vacuum heat collection tubes 41. The distance between the ends of two adjacent solar vacuum heat collection tubes 41 is 5-15cm. The diameter of the solar vacuum heat collection tubes 41 is 47mm or more. The net space distance between the bottom of the solar vacuum heat collection tubes 41 and the top of the ground object is greater than 6.5m. Connecting buckles 42 that are snapped onto the steel strand 3 are fixedly connected to the upper side of both ends of the solar vacuum heat collection tubes 41. The heat collection network 4 is formed by assembling a continuous heat collection pipeline.

[0041] In this embodiment, multiple evenly distributed mounting brackets 51 are fixedly connected to the upper side of the heat collector tube base 5. The mounting brackets 51 are hung on the steel strands 3. The heat collector tube base 5 and the steel strands 3 are vertically arranged in the horizontal direction. The heat collector tube base 5 has a positioning groove 52 that matches the end of the solar vacuum heat collector tube 41. The circulation pipeline of the heat conduction tube 8 and the heat insulation shell on the heat collector tube base 5 form a latitudinal structure. The latitudinal structure and the warp steel strands 3 together form a warp and weft grid structure. The heat conduction tube 8 is made of corrosion-resistant and high-temperature resistant tubing. The steel strands 3 are made of high-strength material. One end of the steel strands 3 is connected to the grid crossbar. The installation position 21 of the 2 is fixedly connected, and the other end is fixedly connected to the installation position 21 of the corresponding side frame crossbar 2. The tension of the steel strand 3 is adjusted by tooling and then tightened and locked. The suspended basket 6 is provided in multiple sets, and multiple sets of the suspended basket 6 can work simultaneously in different sections of the steel strand 3. The motor drive mechanism 62 is equipped with a wireless control module, which can remotely control the direction of movement, speed of movement and start and stop status of the suspended basket 6. One end of the inclined cable 7 is fixedly connected to the side of the column 1, and the other end is anchored to the fixed foundation preset on the ground. The inclined cable 7, the column 1 and the ground form a stable triangular support structure.

[0042] Specifically, the symmetrically installed vertical columns 1 on both sides serve as the core support components. Their bottoms are fixed to the ground by pre-embedded anchor bolts. Combined with the stable triangular support structure formed by the side diagonal bracing 7 and the ground, the vertical stability of the columns and their resistance to wind loads and overturning are ensured. The height difference of more than 100cm between the two columns 1 provides the best lighting angle for the heat collection network 4 and, together with the top grid crossbars 2, forms the overall frame. The evenly distributed installation positions 21 (spaced 10-50cm apart) on the crossbar 2 of the grid structure provide fixed support points for the steel strands 3. After the steel strands 3 are tensioned by tooling, they form a radial support structure, which uses the high-strength material properties to support the weight of the solar collector tubes and related components, achieving flexible high-altitude installation. The solar vacuum collector tubes 41 are connected to the steel strands 3 by the connecting buckles 41 on the upper side of the end, and are arranged in series along the length of the steel strands (the distance between the beginning and end of adjacent tubes is 5-15cm). The diameter is selected from mature specifications of 47mm and above, and a clearance distance of more than 6.5m is maintained from ground objects to ensure that solar radiation energy is fully received and converted into heat energy. The collector tube seat 5 is hung on the steel strands 3 by the upper mounting bracket 51 and is set perpendicular to the steel strands. The heat conduction tube 8 inside is precisely matched with the end of the solar vacuum collector tube 41 through the positioning groove 52 to form a closed heat conduction channel. The heat conduction pipe 8 is made of corrosion-resistant and high-temperature resistant tubing, and is equipped with an external insulation shell to reduce heat loss. At the same time, the heat conduction pipe and the insulation shell form a latitudinal structure, which together with the warp steel strands 3 forms a warp and latitudinal grid structure to achieve concentrated heat conduction and efficient heat retention. Multiple sets of suspended baskets 6 are assembled on the steel strands 3. Their internal pulley mechanism 61 works in conjunction with the motor drive mechanism 62 to move flexibly along the steel strands. The wireless control module equipped with the motor drive mechanism 62 supports remote control of the movement direction, speed and start / stop status. Multiple sets of suspended baskets can work simultaneously in different steel strand sections, providing efficient assistance for processes such as heat collector pipe installation, heat collector pipe hoisting, and pipeline maintenance, reducing the difficulty and cost of high-altitude operations.

[0043] When using the device, firstly, the symmetrical columns 1 on both sides are vertically fixed to the ground using pre-embedded anchor bolts. The diagonal bracing 7 on the sides of the columns forms a triangular support structure with the ground to enhance stability. One column is at least 100cm higher than the other to create the optimal lighting angle. Then, the crossbars 2 of the grid frame are fixed to the top of the columns. Using the symmetrical installation positions 21 spaced 10-50cm apart on the crossbars, the ends of the high-strength steel strands 3 are installed and tensioned using tooling to form a radial support structure. Next, the installation is assisted by the suspended platform 6. Using the pulley mechanism 61 inside the platform and the motor drive mechanism 62 with a wireless control module, multiple platforms are remotely controlled to move synchronously in different sections of the steel strands. The solar vacuum collector tube 41 can be placed inside the suspended platform 6. The suspended platform 6 is installed on the steel strands 3 and needs to be removed later. The solar vacuum collector tube 41 and collector tube base 5 are transported via the suspended platform 6 and hung on the steel strands 3 using the mounting bracket 51. Next, the solar vacuum collector tube 41 is snapped onto the steel strand using end connectors 41 and arranged in series along the length of the steel strand (with a spacing of 5-15cm between the beginning and end of adjacent tubes). This ensures that the end of the collector tube precisely matches the positioning groove 52 of the collector tube seat, guaranteeing that the collector tube diameter is 47mm or larger and that there is a clearance distance of more than 6.5m from ground objects. Then, the corrosion-resistant and high-temperature resistant heat-conducting pipe 8 inside the collector tube seat forms a closed channel with the collector tube. The heat-conducting pipe 8 and the outer insulation shell constitute a latitudinal structure, which together with the longitudinal steel strands forms a warp and weft grid structure. After the solar vacuum collector tube 41 receives solar radiation energy and converts it into heat energy, it is efficiently conducted through the heat-conducting pipe 8 and the insulation shell reduces losses. During daily operation, the collector continuously and stably collects heat and provides heat energy to the vegetable greenhouse, biogas digester, and other facilities below. During later maintenance, the basket can be moved remotely to inspect and repair components such as the collector tube and heat-conducting pipe without affecting normal production and life below.

[0044] In this embodiment, a suspended grid structure solar vacuum collector matrix is ​​installed using the following steps:

[0045] S1: Foundation construction and column fixing: Determine the specifications of column 1 according to the height of the ground objects, ensure that the height difference between the left and right columns is not less than 100cm, mark the symmetrical installation positions and pre-embed anchor bolts; vertically hoist and fix column 1, and ensure vertical stability by tightening the anchor bolts.

[0046] S2: Support structure assembly: Install the diagonal cable 7, with one end fixed to the side of the column 1 and the other end anchored to the ground to form a triangular support; hoist the grid crossbar 2 to the top of the column 1 and fix it, ensuring that the installation positions 21 of the grid crossbar 2 on both sides are symmetrical, so that the columns 1 are connected into an integral frame.

[0047] S3: Warp steel strand erection: Install the two ends of the high-strength steel strand 3 on the mounting positions 21 of the crossbars 2 on both sides of the grid. One end is tensioned and installed with the crossbar 2 of the grid through the tensioning mechanism 9. The tensioning can be adjusted and locked to form a warp support structure, thus completing the installation of all steel strands 3.

[0048] S4: Installation of auxiliary and fixed components: Assemble multiple sets of suspended baskets 6 to steel strands 3, and debug the wireless control motor drive and pulley mechanism to ensure flexible movement; hang the heat collection tube base 5 on the steel strands 3 via the hanging frame 51 through the suspended basket 6, keeping it perpendicular to the steel strands 3.

[0049] S5: The solar vacuum collector tube 41 is hoisted by the basket 6, the steel strand 3 is clamped by the connecting buckle 42 and embedded in the positioning groove 52 of the collector tube seat 5, and installed in series at a beginning-to-end spacing of 5-15cm to ensure that the clearance distance is greater than 6.5m; the heat conduction tube 8 is connected to form a circulation pipeline, and the heat insulation shell is wrapped to form a latitudinal structure, which forms a warp and weft grid with the warp steel strand 3;

[0050] S6: Overall commissioning and acceptance: Check the stability and installation accuracy of each component, and test the operational flexibility through the suspended platform 6; start the system for trial operation to verify the heat collection and heat transfer effects, and complete the installation after confirming that there are no abnormalities.

[0051] Please refer to Figure 8 A solar vacuum collector matrix with a suspension grid structure suitable for vegetable greenhouses:

[0052] This embodiment is designed for a vegetable greenhouse scenario at a facility agriculture base in northern China. The base currently has 10 standardized glass vegetable greenhouses, each 80 meters long and 15 meters wide, with the highest point of the greenhouse roof 4.2 meters above the ground. The greenhouses are used to grow warm-season crops such as tomatoes and cucumbers, requiring the internal temperature to be maintained between 15-30℃ (within the target temperature range of 10-35℃ for agriculture and animal husbandry), while ensuring sufficient natural sunlight to meet the crop's photosynthetic needs. This embodiment uses a suspension network structure to install a solar vacuum collector matrix above the greenhouses, achieving coordinated operation of solar heating and greenhouse production. Planting, irrigation, and harvesting activities can be carried out normally in the greenhouses below the collector matrix.

[0053] During winter operation, the collector array can reach a water temperature of 45-55℃ at the outlet of the collector tubes. It provides heat energy to the heating system inside the greenhouse through the circulation pipeline, maintaining the temperature inside the greenhouse at 18-25℃. This eliminates the need for additional fossil fuel consumption and saves on heating costs every day. In summer, the heat exchange system removes excess heat, which can lower the temperature inside the greenhouse by 3-5℃ and improve the crop growing environment. The net clearance between the collector array and the top of the greenhouse is 7 meters (greater than the requirement of 6.5 meters). The greenhouse below can carry out normal production activities such as planting, irrigation, fertilization, and harvesting. Large agricultural machinery (such as tractors and irrigation vehicles) can pass freely without affecting the original production process.

[0054] Please refer to Figure 9 A suspended grid structure solar vacuum collector matrix adapted for red mud biogas digesters:

[0055] This embodiment is applied to the biogas digester system of a livestock and poultry breeding base in southern China. The base currently has three cylindrical biogas digesters, each with a diameter of 12 meters and a height of 5 meters. The biogas digesters need to maintain an internal temperature of 25-35℃ (within the target environmental temperature range for agriculture and animal husbandry) to ensure stable biogas production. In this embodiment, a solar vacuum collector matrix is ​​installed above the three biogas digesters using a suspension net frame structure to achieve solar heating and insulation. Normal feeding, discharging, and maintenance operations of the biogas digesters can be carried out below the collector matrix.

[0056] After the solar collector matrix is ​​put into operation, the temperature inside the biogas digester is stably maintained at 28-32℃, and the biogas production is increased by 15%-20% compared with the traditional heating method. There are no pollutant emissions, which meets environmental protection requirements. The clearance under the solar collector matrix is ​​greater than 6.5 meters, allowing the biogas digester's feeding vehicle and maintenance equipment to enter and exit normally without affecting the daily operation of the biogas digester. After long-term monitoring, the solar collector structure is stable, the heat collection efficiency is stable and reliable, and it is suitable for the special use scenarios of biogas digesters.
