Description

Technical Field

[0001] This invention relates to the field of artificial turf technology, and in particular to a self-cooling intelligent artificial turf. Background Technology

[0002] Artificial turf originated in the United States in the 1960s. It is a type of artificial turf made from non-living plastic fibers using artificial methods. Unlike natural grass, it does not require the fertilizers and water necessary for its growth. It can withstand the demands of high-intensity sports activities 24 hours a day, and is easy to maintain, drains quickly, and provides excellent surface flatness. Artificial turf is widely used in dedicated playing fields for hockey, baseball, and rugby, public practice fields for sports such as soccer, tennis, and golf, and as ground coverings to beautify indoor environments.

[0003] Artificial turf was first introduced to China in the late 1980s, but it wasn't widely adopted until the mid-to-late 1990s. Along with synthetic running tracks, it became the standard model for school sports field construction, replacing a large number of sports fields that were originally planted with natural grass. Although the application of artificial turf has been limited to some extent due to factors such as sports safety, field characteristics, and public awareness, the production technology of artificial turf has been continuously innovated and improved with technological advancements.

[0004] In current technology, artificial turf is laid directly on the ground, isolating the area beneath and above the ground. In hot summers, the surface temperature of the turf can reach 65-75 degrees Celsius. Therefore, additional cooling equipment is needed. Current technology typically uses artificial ventilation to cool the field, but this method is not very effective for the entire sports field. Summary of the Invention

Detailed Implementation

[0018] 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, and 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.

[0019] Example This invention provides a self-cooling smart artificial turf, see [link / reference]. Figures 1-3 The system includes a base layer 100 placed above the original ground layer, a gravel layer 200 placed above the base layer 100, a buffer layer 300 placed above the gravel layer 200, and an artificial turf layer 400 placed above the buffer layer 300. A water-cooling component 500 is placed between the base layer 100 and the buffer layer 300. A blower component 600 is installed within the base layer 100 to blow air onto the buffer layer 300. After installation, the water-cooling component 500 and the blower component 600 work together to cool the area above the 420 slabs of artificial turf, thus regulating the ambient temperature of the 420 slabs of artificial turf and its area above it within a certain range while still providing the function of a lawn.

[0020] The water-cooling component 500 includes a waterproof layer 510 located below and around the gravel layer 200, forming a cooling pool 520 inside the waterproof layer 510. The gravel layer 200 is located within the cooling pool 520. Multiple inlet pipes 530, multiple drain pipes 540, a main water supply pipe 550, and a main discharge pipe 560 are arranged around the outer side of the cooling pool 520. One end of each inlet pipe 530 and drain pipe 540 is connected to the cooling pool 520, and the other end of all inlet pipes 530 is connected to the main water supply pipe 550, which is equipped with a control valve. The other end of each drain pipe 540 is connected to the main discharge pipe 560. The drain pipes 540 are higher than the inlet pipes 530. During operation, water is supplied through the water supply pipes and through the inlet pipes 530 to the cooling pool 520, allowing the cooling pool 520 to quickly fill with water. When it rains or there is too much water, drainage is carried out through the drainage pipe 540. In this process, the water volume can be prevented from being too high, and the water on the lawn can be drained in time to prevent rainwater from accumulating.

[0021] After water accumulates in the cooling pool 520, when the temperature rises at the artificial turf 420 square meters, cooling can be achieved from below through the cooling pool 520. Simultaneously, the evaporated water vapor can enter the air above the artificial turf 420 square meters, maintaining air humidity. During this process, the blower assembly 600 can further increase the speed of water vapor diffusion, thereby further enhancing the cooling effect.

[0022] Multiple water-resistant pipes 570 are fixedly installed at equal intervals in the middle of the waterproof layer 510. One end of each water-resistant pipe 570 is connected to the buffer layer 300, and the other end is connected to the bottom of the waterproof layer 510. One end of the air blowing assembly 600 is connected to the buffer layer 300 through the water-resistant pipes 570. The water-resistant pipes 570 are made of heat-conducting material. When the air blowing assembly 600 blows air, the air passing through the water-resistant pipes 570 is cooled and kept at a low temperature. When the low-temperature air enters the artificial turf 420 square meters and above it, it can be cooled down quickly.

[0023] A filter screen 580 is installed at one end of the water inlet pipe 530 and the drain pipe 540 near the cooling pool 520. The filter screen 580 can prevent sand and gravel from entering the water inlet pipe 530 or the drain pipe 540.

[0024] In one embodiment, the gravel layer 200 includes a first gravel layer 210 near the base layer 100, a second gravel layer 220 near the buffer layer 300, and a third gravel layer 230 located between the first gravel layer 210 and the second gravel layer 220. The gravel diameter of the first gravel layer 210 and the second gravel layer 220 is 5mm-10mm, and the gravel diameter of the third gravel layer 230 is 20mm-30mm. The smaller diameter gravel on the upper and lower sides allows for better contact with the upper buffer layer 300 and the lower waterproof layer 510. Meanwhile, the relatively larger diameter gravel in the middle creates a relatively large gap space within the gravel layer 200, providing ample space for cooling water. Sufficient cooling water can improve the self-cooling effect of the artificial turf 420 sq m.

[0025] The blower assembly 600 includes a main air supply duct 610, horizontal air supply ducts 620, and vertical air supply ducts 630 embedded in the foundation layer 100. One end of the main air supply duct 610 is located on the outside and connected to a blower. The horizontal air supply ducts 620 are perpendicular to the length of the main air supply duct 610 and are spaced apart along the length of the main air supply duct 610. Multiple vertical air supply ducts 630 are fixedly installed on each horizontal air supply duct 620, and the vertical air supply ducts 630 are detachably and fixedly connected to the water-resistant pipe 570. Specifically, an annular step 571 is formed on the inner side of the lower end of the water-resistant pipe 570, and the upper end of the vertical air supply duct 630 is inserted into the annular step 571 and is interference-fitted through the pipe section of the annular step 571.

[0026] An air outlet duct fitting 700 is detachably installed at the upper end of the water-proof pipe 570; the air outlet duct fitting 700 is located inside the buffer layer 300. When supplying air, the air can pass through the water-proof pipe 570, and can exchange heat with the water outside the water-proof pipe 570.

[0027] The artificial turf layer 400 includes a bottom mat 410 and artificial turf 420 on top of the mat 410; the mat 410 is a breathable material that allows water and air to pass through. Thus, during use, rainwater can penetrate downwards, while cooling air and water vapor below can spread upwards.

[0028] Even better, a first rubber layer 430 is laid on the upper side of the mat 410 and around the artificial turf 420. The first rubber layer 430 can further improve the comfort of the artificial turf 420 slab.

[0029] A cooling hole 310 is vertically formed within the buffer layer 300; an air outlet duct 700 is located within the cooling hole 310, and a second rubber layer 320 is provided within the cooling hole 310 and at the end of the air outlet duct 700 near the artificial turf layer 400. Both the first rubber layer 430 and the second rubber layer 320 are granular rubber layers. This serves both as a buffer and to prevent slipping, without clogging the cooling hole 310.

[0030] The air outlet duct 700 includes a support pipe 710. A limiting ring 720 is provided on the outside of the support pipe 710. The limiting ring 720 divides the support pipe 710 into a first pipe segment 711 and a second pipe segment 712. The first pipe segment 711 is located at the end close to the water-proof pipe 570, and the second pipe segment 712 is located at the end away from the water-proof pipe 570. The first pipe segment 711 is slidably inserted into the water-proof pipe 570. A plurality of air outlet holes 7121 are spaced apart on the outer side wall of the second pipe segment 712. A protective cover 713 is fixed at the end of the second pipe segment 712 away from the first pipe segment 711. The protective cover 713 covers the air outlet holes 7121 and forms an opening at the end close to the first pipe segment 711. Among them, there is a small gap between the outer circumference of the protective cover 713 and the inner wall of the cooling hole 310. This gap allows gas to flow upward, but the size of the gap is smaller than the size of the rubber block of the second rubber layer 320. During use, the rubber of the second rubber layer 320 will not fall down through this gap.

[0031] An elastic sealing component 730 is provided between the limiting retaining ring 720 and the end of the water-proof pipe 570. This elastic sealing component 730 allows the air duct component 700 to elastically recover during movement, thus creating a buffer at that location and improving the comfort of the artificial turf 420 square meters. It should be noted that the diameter of each cooling hole 310 is between 10mm and 30mm. Therefore, when a person walks or runs on the artificial turf 420 square meters, the elastic sealing component 730 further reduces the impact of the cooling holes 310 on the soles of the feet. This improves the comfort of the artificial turf 420 square meters while achieving self-cooling.

[0032] The resilient sealing assembly 730 includes a retaining ring 732, a compression spring 733, and a resilient cloth sleeve 731.

[0033] The retaining ring 732 is threadedly connected to the outer wall of the riser pipe 570; the elastic cloth sleeve 731 has a cylindrical structure. One end of the elastic fabric sleeve 731 is fixedly connected to the limiting ring 720, and the other end is integrally formed with the fixing ring 732. A compression spring 733 is sleeved on the outside of the first pipe section 711, with its two ends abutting against the limiting ring 720 and the fixing ring 732, respectively. The compression spring 733 is located inside the elastic fabric sleeve 731. Furthermore, the compression spring 733 provides elastic force to the upper second pipe section 712, and the outer elastic fabric sleeve 731 creates a sealing effect, ensuring a buffering effect for the artificial turf layer 400 at the cooling hole 310 during use.

[0034] This invention provides a self-cooling intelligent artificial turf 420 sq m. Through a buffer layer 300, a gravel layer 200, and an artificial turf layer 400 disposed on the upper side of the base layer 100, while fulfilling the basic functions of a turf, a water-cooling component 500 and a blowing component 600 are installed within the gravel layer 200 and the base layer 100. This allows for airflow, humidification, and cooling of the entire sports field from within the artificial turf 420 sq m. It enables the regulation of the sports field's air temperature from within the artificial turf 420 sq m, achieving the purpose of self-regulating the field temperature. Simultaneously, during the rainy season, rainwater above the artificial turf 420 sq m can be collected and drained, preventing rainwater accumulation on the surface of the artificial turf 420 sq m.
