Description

Technical Field

[0001] The utility model relates to the technical field of sports field design, in particular to a cage football field. Background Art

[0002] At present, when it rains, the ground of the open-air football field is slippery, which will affect the strength and accuracy of the players' passes to a certain extent, affecting the performance and training effect of the players. In addition, the small ground friction makes it easy to slip or difficult to control during the tackle operation, thus increasing the probability of players getting injured. Now, the method of building an indoor football field is often adopted to avoid rainwater directly falling on the field ground.

[0003] The top of the existing indoor football field is a fixed structure, and sunlight cannot shine into the field. Only indoor lights installed on the top can provide lighting. There are certain differences between the lighting of the lights and natural light. Moreover, the ventilation effect of the indoor football field is poor. Usually, there is no wind or very slow wind speed inside the field, which is quite different from the outdoor environment and cannot provide a field environment similar to the outdoor one, which will have a certain impact on the players' training and competition. In addition, due to the large span of the top of the existing indoor football field, it needs to bear a large load during rainfall. Therefore, a large amount of steel is usually required for support to ensure the strength of the field top, resulting in a high construction cost of the indoor field. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cage football field, which can prevent rainwater from falling into the sports field during rainfall, ensure ventilation on sunny days, and adapt to different weather conditions; and simplify the structure of the field top, reducing the construction cost.

[0005] To achieve the above object, the utility model provides a cage football field, which includes a sports field, a fence arranged around the sports field, and a ceiling covering above the sports field. The ceiling is arched and composed of a plurality of ceiling units spliced together. Each ceiling unit includes a waterproof membrane, a storage component and a stretching component arranged at both ends of the waterproof membrane.

[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", etc. in the description of the present utility model is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0022] AsFigures 1 - 3 As shown in the figure, a cage football field according to a preferred embodiment of the present utility model includes a sports field 1, a fence 2 provided around the sports field 1, and a ceiling 3 covering above the sports field 1. The ceiling 3 is arched and is formed by splicing a plurality of ceiling units 31; each ceiling unit 31 includes a waterproof membrane 4, a storage component 5 and a stretching component 6 provided at both ends of the waterproof membrane 4. The storage component 5 is used to store the waterproof membrane 4, and the stretching component 6 is used to unfold the waterproof membrane 4 to cover above the sports field 1; it further includes a rain sensor provided on the ceiling 3, and both the storage component 5 and the stretching component 6 are electrically connected to the rain sensor for controlling the movement of the storage component 5 and the stretching component 6 according to the rainfall situation.

[0023] Specifically, the sports field 1 includes basic facilities such as grass, goalposts, lighting fixtures and speakers. The fence 2 is arranged around the sports field 1 and encloses the sports field 1 in the middle, which can prevent the football from leaving the sports field 1 during the movement; the ceiling 3 is provided above the fence 2, and the ceiling 3 spans and covers directly above the sports field 1. The ceiling 3 is formed by splicing a plurality of ceiling units 31, and each ceiling unit 31 has a hollow structure in the middle; the waterproof membrane 4 covers the hollow part in the middle of the ceiling unit 31 to close the opening in the middle of the ceiling unit 31. The storage component 5 is arranged on one side of the ceiling unit 31 and can fold or wind the waterproof membrane 4 into the storage component 5; the stretching component 6 is arranged on the ceiling unit 31, and the stretching component 6 can unfold the waterproof membrane 4 to cover the middle of the ceiling unit; the rain sensor is arranged on the upper surface of the ceiling 3, which is convenient for direct contact with rainwater to accurately judge the rainfall situation. When rainfall is detected, the rain sensor sends signals to the storage component 5 and the stretching component 6, and the stretching component 6 starts to drive the waterproof membrane 4 to move and unfold. When the rainfall stops, the rain sensor sends signals to the storage component 5 and the stretching component 6, and the storage component 5 drives the waterproof membrane 4 to be recycled and stored.

[0024] The waterproof membrane 4 is in a stored state when there is no rainfall. When it rains, the rain sensor detects the rainfall and sends signals to the storage component 5 and the stretching component 6. The stretching component 6 starts to act, and the waterproof membranes 4 of each ceiling unit 31 move and unfold until the waterproof membranes 4 in all ceiling units 31 are completely unfolded. At this time, the sports field 1 is covered by the waterproof membrane 4 above, and rainwater cannot fall into the sports field 1, achieving the purpose of rain shelter and waterproofing; the ceiling 3 is an arched structure, and there is a height difference between the middle and both sides of the ceiling 3. The rainwater falling on the ceiling 3 will flow along the ceiling 3 to both sides and drain out, avoiding the accumulation of rainwater on the waterproof membrane 4 and causing greater pressure; when the rainfall stops, the rain sensor sends a rain stop signal, and the storage component 5 starts to act to re-store the waterproof membrane 4 into the storage component 5. At this time, there is no waterproof membrane 4 blocking above the sports field 1, which is equivalent to an outdoor football field and is convenient for athletes to use.

[0025] Preferably, the waterproof membrane 4 is made of PTFE membrane and ETFE membrane, which are characterized by light weight and high strength, and have good light transmittance, so that sunlight can also shine into the interior of the sports field 1 when it is unfolded.

[0026] By providing the retractable waterproof membrane 4, the upper part of the sports field 1 is enclosed during rainfall for rain shelter. When there is no rainfall, the waterproof membrane 4 is stored in the storage assembly 5, which does not affect the lighting and ventilation effects, making the sports field 1 the same as outdoor conditions and facilitating the use of athletes. The arched structure can drain water in time, effectively reducing the load on the waterproof membrane 4 during rainfall, and simplifying the top structure, reducing the construction cost of the sports field 1. The overall structure is simple, easy to maintain, and can be automatically controlled, making it simple and convenient to use.

[0027] Preferably, the ceiling 3 further includes a first cross beam 32 laid on the tops of both sides of the fence 2, and a second cross beam 33 arranged between the two first cross beams 32. The second cross beam 33 is located above the first cross beam 32 and parallel to the first cross beam 32. The two ends of the ceiling unit 31 are respectively connected to one of the first cross beams 32 and the second cross beam 33.

[0028] Specifically, the first cross beam 32 is arranged along the length direction of the sports field 1 and laid on the tops of the opposite sides of the fence 2. The second cross beam 33 is arranged in the middle position between the two first cross beams 32 and parallel to the first cross beam 32. The two ends of the ceiling unit 31 are respectively connected to one of the first cross beams 32 and the second cross beam 33. The waterproof membrane 4 moves telescopically between the first cross beam 32 and the second cross beam 33 to cover the middle part of the ceiling unit 31. The ceiling unit 31 is spliced with the first cross beam 32 and the second cross beam 33 to form the ceiling 3.

[0029] Preferably, the ceiling unit 31 further includes a plurality of arc-shaped support rods 34 connecting the first cross beam 32 and the second cross beam 33. The storage assembly 5 is arranged at one end of the support rod 34, and the stretching assembly 6 moves along the support rod 34 to realize the unfolding or storage of the waterproof membrane 4.

[0030] Specifically, the support rods 34 are respectively arranged on both sides of the second cross beam 33 and arranged along the width direction of the sports field 1. The support rods 34 on the same side of the second cross beam 33 are arranged parallel to each other. The first cross beam 32 and the second cross beam 33 are fixedly connected by the support rods 34. Two adjacent support rods 34 on the same side of the second cross beam 33, the second cross beam 33, and the first cross beam 32 enclose a frame structure member, and the projection of the frame structure member on the ground is a rectangle. Preferably, two adjacent spliced frame structure members share the middle support rod 34. The storage assembly 5 is arranged at one end of the support rod 34, and the waterproof membrane 4 and the stretching assembly 6 are arranged between two adjacent support rods 34.

[0031] In addition, on the basis of ensuring the support strength, the cross-sectional areas of the second cross beam 33, the support rod 34, and the first cross beam 32 can be appropriately reduced to reduce the sunlight shielding of the ceiling 3 structure.

[0032] Preferably, the storage assembly 5 includes a reel tube 51 provided on the first cross beam 32 or the second cross beam 33 and a first motor 52 connected to the reel tube 51. The reel tube 51 is connected to the storage end of the waterproof membrane 4, and the waterproof membrane 4 is wound around the outer periphery of the reel tube 51. The first motor 52 drives the reel tube 51 to rotate.

[0033] Specifically, the reel tube 51 is provided on the second cross beam 33 or the first cross beam 32, or the reel tube 51 is provided on both the second cross beam 33 and the first cross beam 32; the reel tube 51 is fixedly connected to one end of the waterproof membrane 4 to prevent the waterproof membrane 4 from detaching from the reel tube 51. The length direction of the waterproof membrane 4 is perpendicular to the length direction of the reel tube 51. The first motor 52 drives the reel tube 51 to rotate around its own central axis. When the reel tube 51 rotates, it can pull the waterproof membrane 4 to be wound around the outer periphery of the reel tube 51 for storage.

[0034] In addition, structures such as baffles and bearings are provided at both ends of the reel tube 51 to limit the position of the reel tube 51 while the reel tube 51 rotates and prevent the reel tube 51 from moving horizontally and falling off; a protective tube can be sleeved outside the reel tube 51 to prevent the reel tube 51 from being damaged by external impacts. A through hole for the waterproof membrane 4 to pass through needs to be opened on the protective tube.

[0035] Preferably, the stretching assembly 6 includes a traction rod 61 connected to the stretching end of the waterproof membrane 4. The traction rod 61 is arranged perpendicular to the length direction of the waterproof membrane 4. Pulleys 62 are provided at both ends of the traction rod 61, and a second motor 63 for driving the pulley 62 is provided on the pulley 62; it also includes a slide rail 64 arranged along the length direction of the support rod 34 on the support rod 34. The pulley 62 is clamped in the slide rail 64 and drives the traction rod 61 to move along the slide rail 64.

[0036] Specifically, the traction rod 61 is fixedly connected to the other end of the waterproof membrane 4, and the traction rod 61 is arranged perpendicular to the length direction of the waterproof membrane 4; pulleys 62 are provided at both ends of the traction rod 61; slide rails 64 arranged along the length direction of the support rod 34 are provided on the side surfaces of the support rods 34 on both sides of the waterproof membrane 4. The pulley 62 is clamped in the slide rail 64, and the second motor 63 drives the pulley 62 to drive the traction rod 61 to move along the slide rail 64, and at the same time pulls the waterproof membrane 4 to unfold along the support rod 34 direction.

[0037] In addition, when it is necessary to unfold the waterproof film 4, the storage component 5 can also be started to rotate in the reverse direction, cooperating with the stretching component 6 to make the waterproof film 4 unfold more quickly and avoid the waterproof film 4 from being subjected to excessive tensile force. Similarly, when it is necessary to store the waterproof film 4, the stretching component 6 can be started to move in the reverse direction, cooperating with the storage component 5 to make the waterproof film 4 unfold more quickly and avoid the waterproof film 4 from being subjected to excessive tensile force. Limiters or limit protrusions can be provided on both sides of the support rod 34 to prevent the traction rod 61 from moving out of the slide rail 64 during movement and causing inability to recover.

[0038] Preferably, a plurality of hanging rods 41 are fixedly arranged at equal intervals along the length direction of the waterproof film 4. The self-length of the hanging rod 41 is arranged along the width direction of the waterproof film 4. Both ends of the hanging rod 41 are slidably connected to the support rod 34.

[0039] Specifically, the hanging rods 41 are fixedly arranged at equal intervals on the lower surface of the waterproof film 4, and the hanging rods 41 move synchronously with the telescopic movement of the waterproof film 4. When the waterproof film 4 unfolds, the waterproof film 4 moves along the support rod 34. After the hanging rods 41 leave the outer periphery of the storage component 5, due to the action of gravity, both ends of the hanging rods 41 come into contact with the support rod 34. The hanging rods 41 move with the waterproof film 4 to the opposite side until the waterproof film 4 is completely unfolded. At this time, multiple hanging rods 41 are sequentially abutted against the support rods 34 on both sides of the waterproof film 4. The support rods 34 and the hanging rods 41 provide uniform support for the waterproof film 4, greatly improving the stability of the waterproof film 4 and the load it can bear and making the unfolded waterproof film 4 not easily deformed. The hanging rods 41 are stretched and stored synchronously with the waterproof film 4, without affecting the telescopic movement of the waterproof film 4.

[0040] In addition, the hanging rods 41 can also move along the slide rail 64 in the slide rail 64 together with the above-mentioned traction rod 61. A communication groove for the hanging rods 41 and the waterproof film 4 to enter the slide rail 64 is provided at the connection between the support rod 34 and the storage component 5, so that the hanging rods 41 and the waterproof film 4 can enter the slide rail 64 for movement. Pulleys can also be provided at both ends of the hanging rods 41 to make the movement of the hanging rods 41 in the slide rail 64 smoother.

[0041] Preferably, drainage grooves are provided on both sides of the ceiling 3.

[0042] Specifically, the drainage grooves are arranged along the length direction of the first cross beam 32, and the drainage grooves can be fixed on the first cross beam 32. The drainage grooves are arranged on the side of the storage component 5 away from the ceiling 3 or below the storage component 5, so that the rainwater on the surface of the waterproof film 4 can flow along the waterproof film 4 into the drainage grooves. The drainage grooves are communicated with the underground drainage system, and finally the rainwater on the waterproof film 4 and the support rod 34 is discharged into the underground drainage system, improving the drainage efficiency during rainfall.

[0043] Furthermore, when the rainfall is excessive, rainwater may flow along the waterproof membrane 4 to both sides of the waterproof membrane 4 and enter the slide rail 64. Preferably, the drainage groove is communicated with the slide rail 64. Since the slide rail 64 is also an arc-shaped structure, the rainwater entering the slide rail 64 will flow along the slide rail 64 to the lower drainage groove, which can quickly and effectively drain the rainwater falling on the ceiling 3. Therefore, the track groove of the slide rail 64 can be set wider and higher to improve the drainage performance of the slide rail 64. In addition, the waterproof membrane 4 and the slide rail 64 can be tightly connected to reduce the amount of rainwater entering the slide rail 64. The surface of the waterproof membrane 4 is relatively smooth, so the tight connection between the waterproof membrane 4 and the slide rail 64 groove does not affect the smooth movement of the waterproof membrane 4.

[0044] Preferably, the cage football field further includes a handle (not shown in the figure) respectively connected to the storage assembly 5 and the stretching assembly 6 for manually driving the storage assembly 5 and the stretching assembly 6 to move.

[0045] Specifically, gears are provided on the drive shafts of the storage assembly 5 and the stretching assembly 6. The handle is a manually driven gear set, and the gear set meshes with the drive shafts of the storage assembly 5 and the stretching assembly 6 to drive the storage assembly 5 and the stretching assembly 6 to move in a specified direction by rotating the handle, so as to stretch and contract the waterproof membrane 4. It can be manually operated when the rain sensor or the storage assembly 5 or the stretching assembly 6 fails to complete the stretching and contraction of the waterproof membrane 4 and avoid the stadium being unusable due to failure. The handle can extend to the ground for easy operation by the operator.

[0046] In addition, the handle can also be a detachable gear structure. When manually adjusting the storage assembly 5 or the stretching assembly 6, the handle is connected to the storage assembly 5 or the stretching assembly 6 through gear meshing for operation. After the operation is completed, the handle is disassembled and recycled, which can improve the practicality of the handle.

[0047] Preferably, it further includes a power storage device (not shown in the figure) and a solar panel 7 provided above the ceiling 3. The solar panel 7 is electrically connected to the power storage device, and the rain sensor, the storage assembly 5, the stretching assembly 6 and the facilities of the sports field are electrically connected to the solar panel 7 and / or the power storage device.

[0048] Specifically, the solar panel 7 is provided above the ceiling 3 through a connecting rod, so that the solar panel 7 is not easily blocked. The power storage device can be installed in the machine room for storing the electric energy generated by the solar panel 7. The solar panel 7 and the power storage device can supply power to the rain sensor, the storage assembly 5, the stretching assembly 6 and the facilities in the sports field 1, enabling the above devices to work normally, saving energy and being environmentally friendly. In addition, the rain sensor, the storage assembly 5, the stretching assembly 6 and the facilities in the sports field 1 are also connected to the commercial power, so as to ensure the normal use of the stadium when the solar panel 7 and the power storage device cannot provide effective electric energy.

[0049] Preferably, the cage football field further includes a control system, which is electrically connected to the storage component 5, the stretching component 6 and the facilities of the sports field 1.

[0050] Specifically, an operation machine room can be set around the cage football field. The control system is set in the operation machine room to remotely control the storage component 5 and the stretching component 6 through the operating system to complete the telescopic operation of the waterproof membrane 4; the control system controls the switch and brightness of the lighting lamps and the switch and volume of the sound in the sports field 1, improving the practicability of the cage football field and facilitating its use.

[0051] Preferably, the fence 2 includes a plurality of support rods 21 arranged in sequence. The ceiling 3 is supported on the support rods 21. A net is provided between two adjacent support rods 21, and the distance between two adjacent support rods 21 is 1.8 meters to 3 meters.

[0052] Specifically, the support rod 21 is a telescopic structure and is hollowed out inside. The middle part is a cross-shaped steel structure. The hollow structure can be used to place relevant control elements; the distance between the support rods 21 is set to 1.8 meters to 3 meters, which can make the fence 2 not easily deformed by external force impact and can provide a relatively uniform and stable support for the ceiling 3.

[0053] In addition, when the storage components 5 are arranged on both the first cross beam 32 and the second cross beam 33, two stretching components 6 are provided on the two side support rods 34 of the ceiling unit 31. The two stretching components 6 are respectively arranged corresponding to the two storage components 5; when it rains, the stretching components 6 on both sides of the ceiling unit 31 both pull the waterproof membrane 4 to move towards the opposite side of the support rod 34, and the stretching components 6 on both sides finally abut against each other in the middle of the support rod 34 to complete the covering of the ceiling unit 31. A buckle or other structure is provided between the abutted waterproof membranes 4 to ensure the sealing performance; the above method can improve the unfolding efficiency of the waterproof membrane 4 and avoid the waterproof membrane 4 taking too long to close due to the too large span of the stadium, resulting in rainwater falling into the stadium; when the waterproof membrane 4 is stored, it also contracts towards both sides of the ceiling unit 31 to complete the storage.

[0054] The working process of the present utility model is as follows: When it does not rain, the waterproof membrane 4 is in a stored state, wound around the outer periphery of the winding tube 51, and there is no waterproof membrane 4 covering above the sports field 1; when it rains, the rain sensor detects the rain and sends a signal. The second motor 63 starts, drives the pulley 62 to rotate and drives the traction rod 61 to move along the slide rail 64 to pull out the waterproof membrane 4 to cover the middle part of the ceiling unit 31. At the same time, the first motor 52 drives the winding tube 51 to rotate to send out the waterproof membrane 4, and the hanging rod 41 moves with the waterproof membrane 4 and contacts the support rod 34 in sequence. The support rod 34 supports the hanging rod 41 and thus supports the waterproof membrane 4, making the waterproof membrane 4 not easily deformed. When the waterproof membrane 4 is completely unfolded to completely cover above the sports field 1, the storage component 5 and the stretching component 6 stop working; the rainwater drains along the waterproof membrane 4 and the drain trough, and the rainwater cannot fall into the sports field 1.

[0055] When the rainfall stops, the rain sensor emits a signal. The first motor 52 drives the winding tube 51 to rotate in the reverse direction to pull the waterproof film 4 around the outer periphery of the winding tube 51. At the same time, the second motor 63 rotates in the reverse direction to cooperate with the recovery of the waterproof film 4. When the waterproof film 4 is completely recovered to the winding tube 51, the traction rod 61 abuts against the limiting member or the limiting protrusion, and the first motor 52 and the second motor 63 stop working. There is no waterproof film 4 covering above the sports field 1, improving the light transmission and ventilation effects.

[0056] The above operations can be performed through the control system or the handle according to the actual situation, directly controlling the deployment or storage of the waterproof film 4, avoiding the waterproof film 4 being unable to work properly due to component failures.

[0057] This cage football field is powered by the solar panel 7. The electricity storage device is used to store the electric energy generated by the solar panel 7 for subsequent use. When the solar panel 7 or the electricity storage device cannot provide effective electric energy, it can be powered by the commercial power to ensure the normal use of this cage football field.

[0058] In summary, the embodiment of the present utility model provides a cage football field, which covers the sports field with a retractable waterproof film 4 during rainfall to prevent rainwater from falling into the sports field 1 and affecting the use of athletes; when there is no rainfall, the waterproof film 4 is stored in the storage assembly 5, so that there is no waterproof film 4 blocking above the sports field 1, sunlight can shine into the sports field 1, and the ventilation effect is good, being able to be consistent with the outdoor environment, facilitating the use of athletes; on this basis, the waterproof film 4 can be automatically activated according to the rainfall situation to take shelter from the rain, which is simple and convenient to use, and manual operation can also be selected, effectively avoiding being unable to be used due to structural failures; the overall structure is simple, easy to maintain, and can reduce the construction cost; it uses solar power generation, which is energy-saving and environmentally friendly.

[0059] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present utility model.
