Description

Technical Field

[0001] This invention relates to the field of rainwater storage and treatment technology, specifically a sports field that combines storage and water treatment functions. Background Technology

[0002] With the acceleration of urbanization, stormwater runoff management has become a crucial issue in urban infrastructure planning. Traditional stormwater storage tanks effectively alleviate pressure on drainage networks, reduce flood risks, and control initial stormwater pollution by collecting and temporarily storing peak stormwater flows. However, traditional storage tanks require independent construction, and their high land acquisition costs, construction expenses, and subsequent maintenance investment severely restrict their widespread adoption and application in urban areas. This is especially true in core urban areas where land resources are scarce, further exacerbating the difficulties in implementing such facilities.

[0003] Meanwhile, sports fields widely distributed in cities (such as football fields and basketball courts) are often idle during off-peak hours or the rainy season, and their spatial resources are not fully utilized. If the functionality of sports fields could be expanded into composite facilities that combine rainwater storage and treatment, it would not only significantly reduce the construction cost of traditional rainwater storage tanks but also improve the overall utilization rate of urban public facilities. Furthermore, long-term stagnation of stored rainwater can easily lead to water quality deterioration, and direct discharge may cause secondary pollution to receiving water bodies. Therefore, appropriate treatment of stored rainwater is necessary to meet discharge requirements. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and propose a sports field that combines water storage and water treatment functions to solve the aforementioned problems.

[0005] The objective of this invention is achieved through the following technical solution: a sports field that combines water storage and water treatment functions, comprising a field body set on the ground and a foundation pit opened at the top and around the perimeter of the field body. A lifting baffle is installed in the foundation pit and slidably sealed to its opening. Multiple aeration nozzles are installed on the surface of the field body. A screw, an energy storage component, and an aeration fan are installed in the foundation pit. The screw is rotatably mounted on the inner wall of the foundation pit and its end is drivenly connected to the input end of the energy storage component. A nut is connected to the lifting baffle and is threadedly fitted onto the screw. The output end of the energy storage component is drivenly connected to the input end of the aeration fan, and the output end of the aeration fan is connected to the aeration nozzles.

[0006] The lifting baffle includes a mother plate fixedly installed with the bottom wall of the pit and a daughter plate slidably sleeved on the upper part of the mother plate. A motor is slidably installed inside the mother plate, and a lead screw is installed at the output end of the motor. The end of the lead screw rotatably passes through one end of the mother plate and is rotatably connected to the inner wall of the daughter plate. The daughter plate is connected to a nut.

[0007] A switching wheel is provided between one end of the screw and the input end of the energy storage component, with two sides connected to both. A rotating groove is provided at the center of one side of the switching wheel, and a turntable is rotatably arranged in the rotating groove. Multiple grooves are evenly arranged around the turntable, and a first wedge block is slidably arranged on the groove. A return spring is arranged in the groove, and the two ends of the return spring are respectively connected to the first wedge block and the inner wall of the groove. A second wedge block is arranged on the inner wall of the rotating groove, which corresponds to the position and number of the first wedge block.

[0008] The energy storage component includes a worm gear, a ratchet that is driven and connected to the aeration blower, and a limiting member for limiting the rotation of the ratchet. The worm gear and the ratchet are arranged opposite to each other. One side of the worm gear is engaged with a worm that is driven and connected to a screw. A torsion spring with both ends connected to the worm gear and the ratchet is provided between the worm gear and the ratchet.

[0009] The ratchet has an annular groove centered on its center on the side near the worm gear. The worm gear has at least one connecting rod that is slidably connected to the annular groove. The limiting member is a telescopic rod located next to the ratchet, and the end of the telescopic rod has a pawl that matches the ratchet.

[0010] The surface of the site is planted with one or more of the following: Hollow Lotus, Bellows Tree, Cattail, and Canna.

[0011] The beneficial effects of this invention are: (1) By setting up a lifting baffle, the lifting baffle can be activated and cooperate with the sports field to form a water storage tank with adjustable volume in rainy weather, thereby greatly reducing the drainage pressure of the sewer network during the rainy season. There is no need to set up an additional rainwater storage tank, which greatly reduces the cost of rainwater storage.

[0012] (2) By setting up aeration blowers and aeration nozzles, and planting some amphibious plants with water purification functions on the surface of the site as needed, the rainwater on the site can be purified before being discharged into the sewer network when the rainy season is too long and the rainwater has been sitting for too long.

[0013] (3) By setting nuts, screws, switching wheels, first wedge blocks and second wedge blocks, when the lifting baffle rises, the screw drives the switching wheel to rotate; when the lifting baffle falls, the screw cannot drive the switching wheel to rotate, thus avoiding motion interference.

[0014] (4) Through the worm gear, ratchet and telescopic rod, the energy storage of the torsion spring is realized through the self-locking performance of the worm gear and worm. Through the cooperation of the ratchet, pawl and telescopic rod, when the aeration blower needs to be started, the telescopic rod retracts to separate the pawl from the ratchet, and the restoring force of the torsion spring drives the ratchet to rotate, thereby starting the aeration blower.

[0016] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0017] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here.

[0018] A sports field that combines water storage and water treatment functions, see reference. Figures 1-4 The site includes a main body 2 located on the ground and a foundation pit 1 located around the perimeter of the main body 2. Multiple lifting baffles 3 are installed within the foundation pit 1. The lifting baffles 3 are sequentially and sealed together, and are slidably sealed to the upper opening of the foundation pit 1. Multiple drain outlets and aeration nozzles 21 connected to the drainage network are installed on the upper surface of the main body 2. Canna lilies are planted on the upper surface of the main body 2, which can absorb pollutants such as nitrogen, phosphorus, and sulfur dioxide.

[0019] The lifting baffle 3 includes a hollow mother plate 31 fixedly mounted on the inner wall of the pit 1. A hollow daughter plate 32 is slidably fitted onto the upper end of the mother plate 31. The daughter plate 32 matches the size of the opening at the upper end of the pit 1 and is slidably sealed. A motor 33 is slidably mounted inside the mother plate 31, and a lead screw 34 is provided at the output end of the motor 33. The upper end of the lead screw 34 rotatably passes through the upper end of the mother plate 31 and is rotatably connected to the upper end of the daughter plate 32. Ventilation holes are provided on the upper side of the daughter plate 32, the upper side of the mother plate 31, and the lower side of the mother plate 31.

[0020] A screw 4, an energy storage assembly 5, and an aerator 6 are sequentially arranged inside the pit 1. The screw 4 is rotatably mounted on the inner wall of the pit 1. The output end of the energy storage assembly 5 is connected to the input end of the aerator 6 (the energy storage assembly 5 serves as the drive motor for the aerator 6 in existing technology, which will not be described in detail here). A nut 41 is threaded onto the screw 4. The nut 41 is fixedly connected to the sub-plate 32. A switching wheel 7 is provided at the lower end of the screw 4. The lower side of the switching wheel 7 is connected to the input end of the energy storage assembly 5.

[0021] A rotating groove 72 is provided at the center of the upper side of the switching wheel 7. A turntable 73 is rotatably mounted on the rotating groove 72. The turntable 73 is fixedly connected to the screw 4. Multiple grooves 77 are provided around the turntable 73. A first wedge block 74 matching its size and shape is slidably mounted on the groove 77. A return spring 75 is provided on the inner wall of the groove 77, and the return spring 75 is connected to the first wedge block 74. A second wedge block 76 matching the first wedge block 74 is provided on the inner wall of the rotating groove 72.

[0022] When the subplate 32 rises, it moves the nut 41 upwards, causing the screw 4 to rotate in the forward direction, which in turn drives the switching wheel 7 to rotate, storing energy in the energy storage assembly 5. When the subplate 32 falls, it moves the nut 41 downwards, causing the screw 4 to rotate in the reverse direction, while the switching wheel 7 remains stationary.

[0023] The energy storage assembly 5 includes a worm gear 51 and a ratchet 52 arranged parallel to each other. A torsion spring 54 is provided between the worm gear 51 and the ratchet 52, with both ends connected to them. The ratchet 52 has an annular groove 55 centered on the worm gear 51. Two connecting rods 56 are provided on the worm gear 51, and the connecting rods 56 are slidably mounted on the annular groove 55. A worm 53 is engaged on one side of the worm gear 51. The worm 53 is drivenly connected to the switching wheel 7. For those skilled in the art, the drive connection between the worm 53 and the switching wheel 7 can be achieved by using a transmission rod and transmission gear, combined according to actual conditions. Since this is prior art, it will not be described in detail here. A telescopic rod 57 is provided next to the ratchet 52. The end of the telescopic rod 57 is provided with a pawl 58 that matches the ratchet 52, thereby restricting the ratchet 52 from rotating to one side. For those skilled in the art, the ratchet 52 and pawl 58 working together to prevent the ratchet 52 from rotating to one side is a very existing technology. This can be achieved by setting a torsion spring connected to the pawl 58 at the end of the telescopic rod 57, which will not be described in detail here. The ratchet 52 is connected to the input end of the aeration blower 6.

[0024] When a heavy rain begins and the drainage network near site 2 is under immense pressure, the connection between the drain outlets inside site 2 and the drainage network is closed (this is prior art for those skilled in the art, and the structure is similar to a spillway valve on a dam). The sub-plate 32 rises, thus working with site 2 to store rainwater. When the heavy rain ends and the drainage network near site 2 is no longer under immense pressure, the connection between the drain outlets of site 2 and the drainage network is opened, allowing the rising baffle 3 and the rainwater inside site 2 to drain into the drainage network. The rising baffle 3 then descends to its original position. When rainwater in the lifting baffle 3 and the site body 2 has been stagnant for too long and needs to be treated simply before being discharged into the sewer network, the telescopic rod 57 retracts, the pawl 58 no longer abuts against the ratchet 52, and the ratchet 52 is no longer restricted. Under the action of the restoring force of the torsion spring 54, the ratchet 52 rotates, thereby driving the aeration blower 6 to work and generate aeration, which is sprayed out from the aeration nozzle 21, and works with the canna lily to treat the water to a certain extent.

[0025] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above description or related technical or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
