Description

Technical Field

[0001] The present invention relates to the technical field of photothermal power generation, and in particular to a distributed modular heating device. Background Art

[0002] Solar energy technology not only has broad prospects in solar thermal power generation, but also has great potential in the heating market. However, at present, the domestic main technologies used are trough and distributed Fresnel technologies to provide engineering heating project solutions, which require prior planning or modification of the application scenarios. Therefore, the cycle is long and the operation is relatively troublesome. Moreover, if the project is small, the overall cost is relatively high. In order to meet the different heating needs and usage requirements of customers, mature Fresnel solar thermal technology or other solar thermal technologies (such as small trough, etc.) are used to provide engineering solar thermal heating. However, the current solar thermal heating equipment uses the method of manufacturing parts first and then installing, constructing and debugging on site, which makes it inconvenient to use. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention provides a distributed modular heating equipment, which has the advantage of being easy to use and solves the problem that the current solar thermal heating equipment adopts the method of first manufacturing parts and then installing, constructing and debugging on site, which makes it inconvenient to use.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a distributed modular heating equipment, comprising a middle module, a left module and a right module, the left module is hinged on the left side of the middle module, the right module is hinged on the right side of the middle module, the front and rear sides of the top of the middle module are movably connected with adjustable steel cable locks, the left and right sides of the bottom of the middle module are movably connected with electric push rods, the output ends of the two electric push rods are movably connected to the inner sides of the left module and the right module respectively, the top of the right module is rotatably connected with a secondary reflection system and a heat collecting tube, the adjustable steel cable lock is provided with a steel cable pulley mechanism, and the output ends of the steel cable pulley mechanism are fixedly connected to the tops of the left module and the right module respectively;

[0005] The primary reflection system and tracking system are fixed on the middle module, the left module and the right module. The middle module is fixed with a liftable secondary reflection system and a heat collecting tube. The secondary reflection system and the heat collecting tube can be automatically lifted and lowered through steel cables and movable pulleys as the left module and the right module are flipped. Photovoltaic systems are fixedly installed on both sides of the left module and the right module to provide power to the equipment.

[0006] Furthermore, a fixed pull rod is fixedly connected between the left module, the right module and the middle module. The fixed pull rod is arranged horizontally to prevent deformation and displacement of the equipment during transportation and needs to be removed when flipping the left module and the right module.

[0007] Furthermore, both sides of the top of the middle module are fixedly connected with middle pull rods, and the shape of the middle pull rods is an inverted V shape. The two ends of the bottom of the middle pull rods are respectively fixedly connected to the top of the left module and the right module to prevent deformation and displacement of the equipment during transportation, and need to be removed when flipping the left module and the right module.

[0008] Furthermore, the tops of the left module and the right module are fixedly connected with a first cover shell and a second cover shell respectively.

[0009] Furthermore, the reflector systems on the left module and the right module are respectively located inside the first cover shell and the second cover shell.

[0010] Furthermore, the middle module, the left module and the right module are fixedly connected to a reflection system and a tracking system.

[0011] Furthermore, the left module and the right module are fixedly connected to a photovoltaic system on both sides to automatically provide power to the equipment.

[0012] Furthermore, the intermediate module is fixedly connected to the liftable secondary reflection system and the heat collecting tube.

[0013] Furthermore, the first cover and the second cover on both sides of the middle module are equipped with torsion bar springs, and the torque generated by the torsion bar springs is used to balance the gravity torque generated when most of the left and right modules are flipped left and right, so as to reduce the external power required for flipping.

[0014] When in use, after the equipment is transported to the site, first find the north-south direction and place the equipment on the ground, then adjust the foot-type equipment to a horizontal state or have a certain inclination as required, and fix the equipment.

[0015] After connecting the electric push rod to the external power supply, remove the fixed pull rod and the middle pull rod, and control the electric push rod through the switch to push the left module and the right module to flip horizontally. The left module and the right module are simultaneously subjected to three torques: the torque caused by the gravity of the left module and the right module, the reverse deformation torque of the built-in torsion bar spring in the left module and the right module, and the thrust or tension torque of the electric push rod. The torque required for the total thrust or tension of the electric push rod is the difference between the torque caused by the gravity of the left module and the right module and the reverse deformation torque of the built-in torsion bar spring. During the horizontal flipping of the left module and the right module, the secondary reflection system and the collector tube are automatically lifted synchronously through the cable pulley mechanism.

[0016] When the left module and the right module are on the same plane as the middle module, the secondary reflection system and the heat collecting tube are also lifted to a predetermined height, and then the secondary reflection system and the heat collecting tube are locked by pins, thus forming a Fresnel solar thermal collector.

[0017] Connect the customer's input and output pipes to the secondary reflection system and the input and output ports of the collector tube through flanges respectively, check the status of each part, and then operate the photovoltaic system first. When the batteries in the photovoltaic systems in the left and right modules reach the specified capacity, operate the solar thermal system for heating.

[0018] When the equipment needs to be moved to other places, the working process is reversed: first, shut down all control systems and stop running, disassemble the inlet and outlet flange connections, pull out the locking pins, connect the electric push rod external power supply, flip the left module and the right module upwards, and at the same time, the secondary reflection system and the heat collecting tube automatically descend as the left module and the right module flip upwards. When the left module and the right module reach the position, use the fixed pull rod and the middle pull rod to connect the left module and the right module, and the equipment can be dismantled for handling and transportation.

[0019] By means of the above technical solution, the present invention provides a distributed modular heating device, which has at least the following beneficial effects:

[0020] This distributed modular heating equipment adopts a distributed modular container structure. After the equipment is transported to the site, the left module and the right module can automatically flip 90 degrees and be on the same horizontal plane as the middle module. The secondary reflection system and the collector tube of the collector system are automatically lifted to the designed position as the left module and the right module flip, forming a Fresnel solar thermal heating system. The operation of the solar thermal system for heating realizes modularization and equipmentization, and has broad application prospects for small and medium-sized solar heating.

[0026] See also Figure 1-2 A distributed modular heating equipment comprises a middle module 1, a left module 2 and a right module 3, wherein the left module 2 is hinged on the left side of the middle module 1, and the right module 3 is hinged on the right side of the middle module 1. The front and rear sides of the top of the middle module 1 are both movably connected with adjustable steel cable lock buckles 4, and the left and right sides of the bottom of the middle module 1 are both movably connected with electric push rods 5, and the output ends of the two electric push rods 5 are respectively movably connected to the inner sides of the left module 2 and the right module 3, and the top of the right module 3 is rotatably connected with a secondary reflection system and a heat collecting tube 10, and the adjustable steel cable lock buckle 4 is provided with a steel cable pulley mechanism 11, and the output ends of the steel cable pulley mechanism 11 are respectively fixedly connected to the tops of the left module 2 and the right module 3;

[0027] The primary reflection system and tracking system are fixed on the middle module 1, the left module 2 and the right module 3. The middle module 1 is fixed with a liftable secondary reflection system and a heat collecting tube 10. The secondary reflection system and the heat collecting tube 10 can be automatically lifted and lowered through steel cables and movable pulleys as the left module 2 and the right module 3 are flipped. Photovoltaic systems are fixedly installed on both sides of the left module 2 and the right module 3 to provide power to the equipment.

[0028] A fixed pull rod 8 is fixedly connected between the left module 2 and the right module 3 and the middle module 1 , and the fixed pull rod 8 is arranged in a transverse direction.

[0029] Both sides of the top of the middle module 1 are fixedly connected with middle pull rods 9, and the shape of the middle pull rod 9 is an inverted V shape. The two ends of the bottom of the middle pull rod 9 are fixedly connected to the top of the left module 2 and the right module 3 respectively.

[0030] The tops of the left module 2 and the right module 3 are fixedly connected with a first cover shell 6 and a second cover shell 7 respectively.

[0031] The reflector systems on the left module 2 and the right module 3 are located inside the first cover 6 and the second cover 7 respectively.

[0032] Torsion bar springs are installed in the first cover shell 6 and the second cover shell 7 on both sides of the middle module 1. The torque generated by the torsion bar springs is used to balance the gravity torque generated when most of the left and right modules are flipped left and right, so as to reduce the external power required for flipping.

[0033] The distributed modular heating equipment is not only applicable to Fresnel solar thermal systems, but also to different types of solar thermal systems such as small trough solar thermal systems.

[0034] The distributed modular heating equipment can automatically lift the secondary reflection system and the heat collecting tube 10 through the steel cable pulley mechanism 11 when the left and right modules are flipped. When in use, after the equipment is transported to the site, first find the north-south direction and place the equipment on the ground, then adjust the foot-type equipment to a horizontal state or have a certain inclination as required, and fix the equipment.

[0035] After connecting the electric push rod 5 to the external power supply, remove the fixed pull rod 8 and the middle pull rod 9, and control the electric push rod 5 through the switch to push the left module 2 and the right module 3 to flip horizontally. The left module 2 and the right module 3 are simultaneously subjected to three torques: the torque caused by the gravity of the left module 2 and the right module 3, the reverse deformation torque of the built-in torsion bar spring in the left module 2 and the right module 3, and the thrust or tension torque of the electric push rod 5. The torque required for the total thrust or tension of the electric push rod 5 is the difference between the torque caused by the gravity of the left module 2 and the right module 3 and the reverse deformation torque of the built-in torsion bar spring. During the horizontal flipping process of the left module 2 and the right module 3, the secondary reflection system and the heat collecting tube 10 are automatically lifted synchronously through the cable pulley mechanism 11.

[0036] When the left module 2 and the right module 3 are on the same plane as the middle module 1, the secondary reflection system and the heat collecting tube 10 are also lifted to a predetermined height, and then the secondary reflection system and the heat collecting tube 10 are locked by pins, thus forming a Fresnel solar thermal collector.

[0037] Connect the customer's input and output pipes to the secondary reflection system and the input and output ports of the heat collecting tube 10 through flanges respectively, check the status of each part, and then operate the photovoltaic system first. When the batteries in the photovoltaic systems in the left module 2 and the right module 3 reach the specified capacity, operate the solar thermal system for heating.

[0038] When the equipment needs to be moved to other places, the working process is reversed: first, shut down all control systems and stop operation, disassemble the inlet and outlet flange connections, pull out the locking pins, connect the electric push rod 5 to the external power supply, flip the left module 2 and the right module 3 upward by 90°, and at the same time, the secondary reflection system and the heat collecting tube 10 automatically descend as the left module 2 and the right module 3 are flipped upward. When the left module 2 and the right module 3 reach the position, use the fixed pull rod 8 and the middle pull rod 9 to connect the left module 2 and the right module 3, and the equipment can be dismantled for handling and transportation.

[0039] The function of the adjustable steel cable lock 4 is to adjust the length of each steel cable when assembling the equipment, eliminate manufacturing and assembly errors, and make the left module 2 and the right module 3 synchronized with the secondary reflection system and the heat collecting tube 10.

[0040] The distributed modular heating equipment adopts a distributed modular container structure. After the equipment is transported to the site, the left module 2 and the right module 3 can automatically flip ninety degrees and be on the same horizontal plane as the middle module 1. The secondary reflection system and the heat collecting tube of the heat collecting system are automatically lifted to the designed position as the left module 2 and the right module 3 are flipped, forming a Fresnel solar thermal heating system. The operation of the solar thermal system for heating realizes modularization and equipmentization, and has broad application prospects for small and medium-sized solar heating.
