[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings:

[0026] Reference Figure 1 This invention discloses an integrated ultra-large aperture butterfly solar concentrator processing equipment, comprising:

[0027] Inflatable membrane room 1. In order to show the internal structure, the inflatable membrane room 1 is not enclosed in the figure. The inflatable membrane room 1 replaces the steel structure factory building, which is more convenient and can be used for on-site processing.

[0028] Inflatable mold core 2 is installed inside the inflatable membrane room 1;

[0029] The spraying device 3 is installed on the inflatable mold core 2; and

[0030] Drive device 4 that drives the spraying device 3 to move on the inflatable mold core 2;

[0031] The inflatable mold core includes a base plate 21, an annular pressure plate 22, and a mold core body 23. The base plate 21 is disposed on the ground of the inflatable membrane room 1, and the annular pressure plate 22 is disposed on the base plate 21. The mold core body 23 has the same shape as the condenser lens to be processed and is a tensioned membrane. The concave surface of the mold core body 23 faces downward and its edge is fixedly connected to the annular pressure plate 22. The spraying device 3 includes a working platform 31 and a paint tank 32 and a fabric rack 33 disposed on the working platform 31. The fabric on the fabric rack 33 is laid onto the mold core body 23 through the paint in the paint tank 32. One end of the paint tank 32 passes through the working platform 31 and a spray nozzle 321 is opened on the end face.

[0032] In this embodiment, the work platform 31 is also equipped with a fabric guide for pulling the fabric.

[0033] Specifically, to construct the inflatable membrane room 1, the site must first be leveled and the ground hardened. The inflatable membrane room 1 is then installed on the ground and cleaned. A core body 23 of the corresponding size is selected based on the diameter of the condenser lens, and the core body 23 is fixedly connected using an annular pressure plate 22. To ensure the annular pressure plate 22 is flat, a base plate 21 is provided on its bottom surface. The annular pressure plate 22 has a layered structure, formed by multiple annular pressure blocks. During fixing, the core body 23 is placed at the connection point of the annular pressure plate 22's layers, and the annular pressure blocks are connected using screws, bolts, etc. To ensure a seal, the interfaces of the upper and lower annular blocks are staggered during installation.

[0034] Furthermore, based on the design of the condenser lens, the opening diameter is generally between 3-20 meters, the opening depth is 3-5 meters, and the inflation pressure of the mold core body 23 is between 15-50 kPa. This means that a constant pressure controller is installed inside the mold core body 23. To monitor the air pressure and ensure its stability, a pressure sensor 6 is installed in the mold core body 23. To ensure machining accuracy, a laser rangefinder 7 is installed in the mold core body 23 to monitor changes in its dimensions in real time and ensure machining precision.

[0035] Reference Figure 2 The drive unit 4 includes a truss 41 spanning above the main body 23 of the mold core, a first track 42 mounted on the truss 41, and a work vehicle 47 connected to the first track 42. The work platform 31 is fixedly connected to the work vehicle 47 via a connector, allowing the work platform to move with the work vehicle 47. The wheels of the work vehicle 47 are connected to the first track 42.

[0036] In this embodiment, the work vehicle 47 contains a drive motor that moves the wheels. The truss 41 is semi-circular, meaning that the spraying device 3 can move along the truss 41.

[0037] Reference Figure 3 The drive device 4 also includes a base 43 located at both ends of the truss 41 and an annular drive track 45 connected to the base 43.

[0038] Furthermore, the annular drive track 45 includes an annular seat 451 and a second track 452 sleeved on the outside of the annular seat 451. A roller 44 cooperating with the second track 452 is provided on the opposite side of the base 43. A driver for driving the roller 44 is provided inside the base 43. The drive device 4 also includes an annular track 46 located below the base 43, and wheels cooperating with the annular track 46 are also provided below the base 43. This arrangement allows the truss 41 to rotate 360°, ensuring that the spraying device 3 can perfectly cover the mold core body 23.

[0039] In this embodiment, the first track 42, the second track 452, and the circular track 46 can be other transmission tracks such as chains and racks, and the corresponding wheels and rollers can be other transmission wheels such as sprockets and gears.

[0040] The processing method of this processing equipment includes:

[0041] Install the mold core body 23 onto the annular pressure plate 22, start the constant pressure controller, and monitor the size of the mold core body 23 according to the laser rangefinder;

[0042] Clean the surface of the mold core body 23 and apply a release agent to the surface of the mold core body 23;

[0043] Then the paint (which can be resin) in the paint can 32 is applied to the surface of the mold core body 23 through the spray nozzle 321;

[0044] Spread the fiberglass cloth on the cloth rack 53 evenly onto the surface of the mold core body 23;

[0045] After laying one layer, the coating and fabric spreading steps are repeated so that at least two layers of fabric are laid on the surface of the core body 23;

[0046] Electric heating elements are evenly installed in the fiberglass fabric;

[0047] After installation, spread the fiberglass cloth evenly on the electric heating belt, and lay at least two layers.

[0048] During the laying process, a connecting seat is installed at a pre-set position on the main body 23 of the mold core;

[0049] After the laying is completed, connect the umbrella-shaped warp frame to the connecting seat with bolts, and install the circumferential weft frame on the umbrella-shaped warp frame;

[0050] Tensile membrane material is stretched onto a warp and weft skeleton;

[0051] The core body 23 and the tensioned membrane material are connected and fixed by bolts and adhesive, and the gaps are filled with lightweight adhesive.

[0052] The inflatable mold core 23 is lifted and flipped so that the concave surface faces upward.

[0053] clean;

[0054] Spray-coating the core body 23;

[0055] Drying complete.

[0056] In this embodiment, in order to accelerate the laying process, an annular hot air pipe 5 is provided inside the core body 23. The hot air pipe 5 is used to generate hot air at 35-40°C to accelerate the curing speed of the coating.

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art.
