Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic running track technology, specifically a permeable plastic running track. Background Technology
[0002] Plastic running tracks, also known as all-weather athletic tracks, are composed of polyurethane prepolymer, mixed polyethers, waste tire rubber, EPDM rubber granules or PU particles, pigments, additives, and fillers. Plastic running tracks are characterized by good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. During exercise, the elasticity of the plastic flooring provides an invisible rebound force to the athlete's ankles, thereby reducing the risk of injury.
[0003] To effectively prevent surface water from seeping into the base layer, a waterproof layer is usually laid under the plastic layer. This makes it difficult for water to seep downwards during rainy or snowy weather, and water can easily accumulate on the plastic track. After prolonged soaking, the water accumulation can also affect the service life of the plastic track. Therefore, a permeable plastic track has been proposed. Utility Model Content

A winding rope is wound around the outer surface of the winding wheel, and a receiving box is fixedly connected to the other end of the winding rope.
[0006] Furthermore, the drainage layer includes two drainage boards located between the concrete layer and the permeable layer, respectively. A cavity is formed between the two drainage boards, and multiple reinforcing ribs are provided between the two drainage boards. Several permeable holes are opened on the outer surface of the upper drainage board.
[0007] Furthermore, the interior of the polyurethane surface layer has several water-permeable slits.
[0008] Furthermore, a support plate is fixedly connected inside the drainage ditch, and a rotating shaft is rotatably passed through the outer surface of the support plate.

[0011] Furthermore, the drainage layer is connected to the interior of the drainage ditch, and the connection is inclined.
[0012] Furthermore, the outer surface of the receiving box is provided with several drainage holes.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1:
[0022] Please refer to the following: Figures 1-4 This utility model provides a technical solution: a permeable plastic running track, including a base layer 1 and a drainage ditch 7. A concrete layer 2 is provided on top of the base layer 1, a drainage layer 3 is provided on top of the concrete layer 2, a polyurethane surface layer 5 is provided on top of the drainage layer 3, and a surface particle layer 6 is provided on top of the polyurethane surface layer 5. Two winding shafts 9 are rotatably connected inside the drainage ditch 7. A winding wheel 10 is fixedly fitted onto the outer surface of each of the two winding shafts 9, and a winding rope 11 is wound around the outer surface of the winding wheel 10. The other end is fixedly connected to a receiving box 12. Specifically, when water accumulates on the surface granular layer 6 of the plastic track, the water enters the drainage layer 3 through the drainage seam and the permeable layer 4, and is discharged into the drainage ditch 7 in the cavity 8. The receiving box 12 collects the debris. When it is necessary to clean the debris in the receiving box 12, the two winding shafts 9 rotate simultaneously, thereby driving the winding wheel 10 to rotate and winding the winding rope 11, thereby retracting the receiving box 12 and cleaning the impurities in the receiving box 12.
[0023] In this embodiment, the drainage layer 3 includes two drainage boards located between the concrete layer 2 and the permeable layer 4, respectively. The two drainage boards form a cavity 8, and multiple reinforcing ribs 18 are provided between the two drainage boards. Several permeable holes are opened on the outer surface of the upper drainage board. Specifically, when water flows through the drainage layer 3, it enters the cavity 8 through the permeable holes, and the stability of the drainage layer 3 is increased by the reinforcing ribs 18.
[0024] In this embodiment, a number of water-permeable slits are provided inside the polyurethane surface layer 5. Specifically, when water flows through the polyurethane surface layer 5, it is discharged through the water-permeable slits.
[0025] In this embodiment, a support plate is fixedly connected inside the drainage ditch 7. A rotating shaft rotatably passes through the outer surface of the support plate. A crank handle 15 is fixedly connected to the top outer surface of the rotating shaft, and a driving bevel gear 14 is fixedly connected to the bottom outer surface of the rotating shaft. A driven bevel gear 13 is fixedly sleeved on the outer surface of one of the winding shafts 9. The driving bevel gear 14 and the driven bevel gear 13 are movably meshed. Specifically, when the crank handle 15 is turned, the crank handle 15 drives the rotating shaft to rotate and causes the driving bevel gear 14 to rotate. The driving bevel gear 14 drives the driven bevel gear 13 to rotate, thereby causing the winding shaft 9 to rotate.
[0026] In this embodiment, sprockets 16 are fixedly sleeved on the outer surfaces of the two take-up shafts 9, and a chain 17 is wound between the two sprockets 16. Specifically, when the take-up shaft 9 rotates, it drives the sprockets 16 on it to rotate, and the chain 17 causes the other sprocket 16 to rotate, so that the two sprockets 16 rotate at the same time, driving the two take-up shafts 9 to rotate at the same time.
[0027] In this embodiment, a grate 19 is provided on the top outer surface of the drainage ditch 7. Specifically, by opening the grate 19, the receiving box 12 is lifted upwards to clean the debris inside the receiving box 12.
[0028] In this embodiment, the drainage layer 3 is internally connected to the drainage channel 7, and the connection is inclined. Specifically, the water in the drainage layer 3 flows into the drainage channel 7.
[0029] In this embodiment, the outer surface of the receiving box 12 is provided with a number of leakage holes. Specifically, by providing leakage holes, the water inside the receiving box 12 can be discharged through the leakage holes, so as to avoid the receiving box 12 accumulating too much water and becoming too heavy to lift.
[0030] Working principle: When water accumulates on the surface granular layer 6 of the plastic track during use, the water enters the drainage layer 3 through the drainage seam and permeable layer 4, and is discharged into the drainage ditch 7 in the cavity 8. The receiving box 12 collects the debris. When it is necessary to clean the debris in the receiving box 12, the crank handle 15 is turned. The crank handle 15 drives the active bevel gear 14 to rotate, which in turn drives the driven bevel gear 13 to rotate, causing one side of the winding shaft 9 to rotate, which in turn drives the sprocket 16 on it to rotate. Under the action of the chain 17, the other sprocket 16 is driven to rotate, causing both winding shafts 9 to rotate simultaneously, thereby driving the winding wheel 10 to rotate, winding the winding rope 11, thus retracting the receiving box 12 and cleaning the impurities in the receiving box 12.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
