Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of municipal engineering, in particular to a sports ground rapid drainage system. BACKGROUND

[0002] Sports ground is the activity site of athletes and activity personnel. Large sports ground is usually an open-air building and is often used for large activities such as sports events and social performances. The sports ground usually has a plastic track. However, the plastic track is prone to peeling and drumming after being soaked in rainwater for a long time. Therefore, it is particularly important to set a good drainage system for the sports ground.

[0003] The existing sports ground drainage system usually opens a drainage ditch on the surface of the soil layer of the sports ground and installs a well lid or a grid plate at the slot of the drainage ditch, so that the rainwater can flow to the drainage ditch through the well lid or the grid plate and be discharged outward through the drainage ditch, realizing the drainage effect of the sports ground. The well lid or the grid plate can block foreign matters on the sports ground from entering the drainage ditch, reducing the possibility that the drainage ditch is blocked by foreign matters and causes the rainwater to be unable to be discharged outward.

[0004] According to the technical scheme in the above, the inventor believes that the following defects exist: The size of the conventional well lid or grid plate drainage port is fixed, and the drainage capacity is limited. When it rains heavily, the well lid or grid plate is often not drained in time, causing rainwater to collect at the drainage port, and further causing the sports ground to be waterlogged. Therefore, it needs to be further improved. SUMMARY

DETAILED DESCRIPTION

[0041] The following will be described in detail with reference to the accompanying drawings. Figures 1-9 The application is further described in detail.

[0042] The embodiment of the application discloses a sports ground rapid drainage system.

[0043] Reference is made to Figure 1 A sports ground rapid drainage system, comprising a drainage ditch 1 arranged in a soil layer of a sports ground, a plurality of installation outer frames 2 are fixedly installed at the groove opening of the drainage ditch 1, and all the installation outer frames 2 are uniformly distributed along the length direction of the drainage ditch 1; in the embodiment, the installation outer frame 2 is arranged in a rectangular ring structure, and adjacent installation outer frames 2 are arranged in abutment.

[0044] Reference is made to Figure 2 , Figure 3 The groove opening of the drainage ditch 1 is provided with an installation sink 13, the installation outer frame 2 is installed in the installation sink 13, and the upper surface of the installation outer frame 2 is flush with the groove opening of the drainage ditch 1; in the embodiment, a plurality of countersunk bolts 22 are installed on the upper surface of the installation outer frame 2, all the countersunk bolts 22 are sequentially arranged in the bottom wall of the installation outer frame 2 and the installation sink 13 and are threadedly connected to the installation sink 13, and the installation outer frame 2 is detachably installed at the groove opening of the drainage ditch 1 through the countersunk bolts 22; in this way, after the installation outer frame 2 is installed in the installation sink 13, the upper surface of the installation outer frame 2 can be flush with the groove opening of the drainage ditch 1, so that the flatness of the overall structure is improved.

[0045] Reference is made to Figure 3 , Figure 4The inner side wall of each installation outer frame 2 is slidably installed with an installation inner frame 3, and the outer side wall of the installation inner frame 3 is kept in close contact with the inner side wall of the installation outer frame 2. In this embodiment, the upper surface of the installation inner frame 3 is kept flush with the upper surface of the installation outer frame 2, and the thickness of the installation inner frame 3 is greater than that of the installation outer frame 2. The bottom of the installation groove 13 is provided with a sliding groove 14 for the installation inner frame 3 to slide towards the bottom of the drainage ditch 1.

[0046] Referring to Figure 4 , Figure 5 , one end of the outer side wall of the installation inner frame 3 close to the bottom of the drainage ditch 1 is fixed with an installation plate 31. In this embodiment, the installation plate 31 is provided with two and symmetrically installed on the two opposite outer side walls of the installation inner frame 3. The installation plate 31 is located at the lower part of the installation outer frame 2, and a plurality of tension springs 32 are installed between the upper surface of the installation plate 31 and the lower surface of the installation outer frame 2. All the tension springs 32 are arranged along the length direction of the installation plate 31. The tension springs 32 normally keep the upper surface of the installation inner frame 3 flush with the upper surface of the installation outer frame 2. The installation inner frame 3 is slidably installed on the installation outer frame 2 through the tension springs 32.

[0047] Referring to Figure 2 , Figure 3 , a plurality of blocking plates 33 are installed in the installation inner frame 3. The two sides of the blocking plate 33 are respectively installed on the two opposite inner side walls of the installation inner frame 3, and there is a gap between adjacent blocking plates 33 for rainwater to enter the drainage ditch 1. In this way, rainwater can flow into the drainage ditch 1 through the gap between adjacent blocking plates 33 and be discharged outward. Foreign matters in the outside world can be blocked on the upper surface of the blocking plate 33, reducing the possibility of foreign matters falling into the drainage ditch 1 and causing the drainage ditch 1 to be blocked.

[0048] Referring to Figure 3 , Figure 6 , the side wall of each blocking plate 33 is provided with a sliding groove 331, and a sliding plate 34 is slidably installed in the sliding groove 331. In this embodiment, the sliding plate 34 is normally partially exposed from the slot of the sliding groove 331. The sliding plate 34 is provided with a pulling assembly 4. When the installation inner frame 3 moves towards the side close to the bottom of the drainage ditch 1, the pulling assembly 4 forces the sliding plate 34 to move into the sliding groove 331.

[0049] Referring to Figure 4 , Figure 6, the pulling assembly 4 comprises a pulling rope 41 and a second compression spring 42. One end of the pulling rope 41 is fixedly installed on the side wall of the sliding plate 34 close to the bottom of the sliding groove 331, and the other end passes through the side wall of the blocking plate 33, the side wall of the installation inner frame 3 and the inner side wall of the installation outer frame 2 in sequence and is fixedly connected to the inner side wall of the installation outer frame 2. The outer side wall of the installation inner frame 3 is provided with a second avoiding groove 38 for avoiding the pulling rope 41, and one end of the second avoiding groove 38 penetrates the upper surface of the installation inner frame 3. A plurality of second compression springs 42 are arranged in the sliding groove 331 and are arranged at intervals. One end of the second compression spring 42 is fixedly connected to the sliding plate 34, and the other end is fixedly connected to the sliding groove 331. The second compression spring 42 normally makes the sliding plate 34 partially exposed to the sliding groove 331.

[0050] When rainwater accumulates on the upper surface of the installation inner frame 3 and cannot be discharged into the drainage ditch 1 in time, as the amount of rainwater accumulates, the installation inner frame 3 is pressed by the rainwater and moves downward towards the bottom of the drainage ditch 1. During the downward movement of the installation inner frame 3, the pulling rope 41 can pull the sliding plate 34 and force the sliding plate 34 to move towards the side close to the bottom of the sliding groove 331, thereby expanding the gap between adjacent blocking plates 33 and increasing the discharge speed of the rainwater.

[0051] Referring to Figure 4 , Figure 5 , the side wall of each installation plate 31 away from the installation inner frame 3 is provided with a first clamping groove 311, and the two opposite side walls of the drainage ditch 1 are provided with a second clamping groove 11. In the embodiment, the second clamping groove 11 is spaced apart from the installation outer frame 2 and is located below the first clamping groove 311. Each first clamping groove 311 is provided with a fixing assembly 6. When the first clamping groove 311 moves to be opposite to the second clamping groove 11, the fixing assembly 6 is clamped in the corresponding second clamping groove 11.

[0052] Referring to Figure 5 , Figure 7 , the fixing assembly 6 comprises a clamping column 61 and a first compression spring 62. The clamping column 61 is slidingly installed in the first clamping groove 311, and the first compression spring 62 is installed in the first clamping groove 311. One end of the first compression spring 62 is fixedly connected to the clamping column 61, and the other end is fixedly connected to the bottom of the first clamping groove 311. When the first clamping groove 311 moves to be opposite to the second clamping groove 11, the first compression spring 62 normally clamps the clamping column 61 in the second clamping groove 11. In this way, when a large amount of rainwater accumulates on the upper surface of the installation inner frame 3 and forces the installation inner frame 3 to move towards the side close to the drainage ditch 1, the first clamping groove 311 can move to be opposite to the second clamping groove 11. At this time, the clamping column 61 is clamped in the second clamping groove 11 under the action of the first compression spring 62, thereby fixing the installation inner frame 3, making the sliding plate 34 slide and remain in the sliding groove, keeping the gap between adjacent blocking plates 33, and allowing rainwater to quickly discharge into the drainage ditch 1.

[0053] With reference to Figure 5 , Figure 7 , the top wall of the inner mounting frame 3 is provided with a movable slot 37, which is a circular slot in this embodiment. A through hole 372 is formed in the side wall of the movable slot 37 and is connected to the first clamping slot 311. An unlocking assembly 7 is mounted on the movable slot 37 and is used to separate the clamping column 61 from the second clamping slot 11. In this way, after the rainwater is drained, the clamping column 61 is forced to separate from the second clamping slot 11 by the unlocking assembly 7. The inner mounting frame 3 is moved to be flush with the outer mounting frame 2 under the action of the tension spring 32, which improves the flatness of the overall structure and reduces the possibility of the inner mounting frame 3 sinking and affecting the athlete's movement.

[0054] With reference to Figure 5 , Figure 7 , the unlocking assembly 7 includes a movable rod 71 and a connecting rope 72. The movable rod 71 is vertically inserted into the movable slot 37 and is slidingly mounted on the movable slot 37. One end of the connecting rope 72 is fixedly connected to the clamping column 61, and the other end is inserted into the through hole 372 and fixedly connected to the movable rod 71. A lifting ring 711 for lifting the movable rod 71 is fixedly installed on the top wall of the inner mounting frame 3. In this way, pulling the movable rod 71 upwards forces the movable rod 71 to slide along the axial direction of the movable slot 37, which can pull the connecting rope 72 and force the clamping column 61 to separate from the second clamping slot 11, so that the upper surface of the inner mounting frame 3 can be moved to be flush with the upper surface of the outer mounting frame 2.

[0055] With reference to Figure 7 , in this embodiment, there is a gap between the top wall of the movable rod 71 and the top wall of the inner mounting frame 3 to form a mounting space for the lifting ring 711. The lifting ring 711 of the movable rod 71 is normally below the upper surface of the inner mounting frame 3, which ensures the flatness of the upper surface of the inner mounting frame 3.

[0056] With reference to Figure 4 , Figure 7 , in this embodiment, the movable rod 71 is slidingly and rotationally connected to the movable slot 37. A abutting plate 712 is fixedly installed on the outer peripheral wall of the movable rod 71. A first avoiding slot 371 is formed in the inner peripheral wall of the movable slot 37 for the abutting plate 712 to slide. The first avoiding slot 371 penetrates through the side wall of the inner mounting frame 3 close to the outer mounting frame 2. The side wall of the outer mounting frame 2 close to the first avoiding slot 371 is provided with an abutting slot 21. When the top wall of the inner mounting frame 3 is flush with the top wall of the outer mounting frame 2, the abutting plate 712 is directly opposite the abutting slot 21. In this way, on sunny days, rotating the movable rod 71 forces the abutting plate 712 to rotate and abut against the abutting slot 21, thereby fixing the inner mounting frame 3 to the outer mounting frame 2, which reduces the possibility of the inner mounting frame 3 sinking and affecting the athlete's movement when the athlete steps on the inner mounting frame 3.

[0057] With reference to Figure 6 ,Figure 8 The rotation rod 332 is fixed to one side of the blocking plate 33 away from the sliding plate 34, and is rotationally connected to two opposite inner side walls of the mounting inner frame 3. Each blocking plate 33 is rotationally connected to the mounting inner frame 3 through the rotation rod 332. The blocking plate 33 is normally in a horizontal state. The pull rope 41 passes through the side wall of the blocking plate 33 and the rotation rod 332 in sequence and is connected to the mounting outer frame 2.

[0058] With reference to Figure 7 , Figure 8 The bottom wall of the mounting inner frame 3 is provided with a mounting groove 35. One end of each rotation rod 332 away from the blocking plate 33 passes through the side wall of the mounting inner frame 3 and extends into the mounting groove 35. The side wall of the mounting groove 35 is rotationally provided with a rotation shaft 351. The outer circumferential wall of the rotation shaft 351 is coaxially fixed with a driving pulley 352. The outer circumferential wall of the rotation rod 332 is coaxially fixed with a driven pulley 353. In this embodiment, a plurality of driven pulleys 353 are provided, and all the driven pulleys 353 are correspondingly arranged with all the blocking plates 33. Each driven pulley 353 is coaxially fixed to the outer circumferential wall of the rotation rod 332 corresponding to the blocking plate 33. A belt 354 is wound between the driving pulley 352 and all the driven pulleys 353. The belt 354 is used to drive the driving pulley 352 and all the driven pulleys 353 to rotate synchronously.

[0059] With reference to Figure 8 , Figure 9 The mounting groove 35 is fixedly provided with a sliding seat 36. In this embodiment, two groups of sliding seats 36 are symmetrically arranged below the two sides of the rotation shaft 351. A sliding strip 362 is slidingly arranged between the two groups of sliding seats 36. The sliding direction of the sliding strip 362 is perpendicular to the axial direction of the rotation shaft 351. The rotation shaft 351 is provided with a rotation assembly 5 for driving the rotation rod 332 to rotate. When the first clamping groove 311 moves to the opposite side of the second clamping groove 11, the rotation assembly 5 drives the rotation rod 332 to rotate. In this way, the blocking plate 33 is driven to rotate by the rotation assembly 5. The rotated blocking plate 33 can further increase the gap between adjacent blocking plates 33, thereby further increasing the drainage speed of the rainwater.

[0060] With reference to Figure 8 , Figure 9 The rotation assembly 5 includes a gear 51, a rack 52, and a driving member 53. The gear 51 is coaxially fixed to the outer circumferential wall of the rotation shaft 351. The rack 52 is fixedly installed on the upper surface of the sliding strip 362 and is in meshing transmission with the gear 51. The length direction of the rack 52 is consistent with the length direction of the sliding strip 362. The rack 52 is slidingly installed on the sliding seat 36 through the sliding strip 362.

[0061] With reference to Figure 7 , Figure 9The bottom of the sliding sink 14 is provided with a receiving groove 15. In this embodiment, the driving component 53 is a linear motor, which is fixedly installed in the receiving groove 15. The linear motor is slidably installed with a second docking block 55. The second docking block 55 is partially exposed in the receiving groove 15. The side wall of the second docking block 55 near the rack 52 is provided with a docking groove 551. The side wall of the sliding bar 362 away from the rack 52 is fixedly installed with a first docking block 54. The shape of the first docking block 54 is adapted to the shape of the docking groove 551. When the first locking groove 311 moves to be opposite to the second locking groove 11, the first docking block 54 is inserted into the docking groove 551.

[0062] When a large amount of rainwater compresses the inner frame 3 and moves it downward, causing the first locking groove 311 to move opposite the second locking groove 11, the first docking block 54 is inserted into the docking groove 551 and the locking post 61 is locked into the second locking groove 11. Then, the linear motor is started to drive the second docking block 55 to slide. Under the meshing transmission of the gear 51 and rack 52, and the meshing transmission of the driving pulley 352 and driven pulley 353, all the blocking plates 33 are driven to rotate, thereby increasing the distance between adjacent blocking plates 33 so that rainwater can pass through quickly. On the other hand, when foreign objects are blocked between adjacent blocking plates 33, the linear motor drives the rack 52 to slide back and forth, which can drive the blocking plates 33 to rotate back and forth, thereby agitating the foreign objects in the inner frame 3 and reducing the possibility of the inner frame 3 being blocked by foreign objects.

[0063] Reference Figure 8 , Figure 9 A first limiting groove 521 is provided on the side wall of the sliding strip 362 near the sliding seat 36, and a second limiting groove 361 is provided on the side wall of the sliding seat 36 near the sliding strip 362, penetrating the sliding seat 36. The first limiting groove 521 is normally positioned opposite to the second limiting groove 361. A limiting post 56 is slidably installed in the first limiting groove 521, and one end of the limiting post 56 is inserted into the second limiting groove 361. With this design, when the top wall of the inner frame 3 is flush with the top wall of the outer frame 2, the limiting post 56 is inserted into the second limiting groove 361, thereby fixing the rack 52 and restricting the rotation of the blocking plate 33. This reduces the possibility of the blocking plate 33 rotating and causing ankle sprains when people step on it.

[0064] Reference Figure 8 , Figure 9, the groove bottom of the sliding groove 14 is fixedly installed with a top post 12, the top post 12 is coaxially arranged with the second limiting groove 361, when the first clamping groove 311 moves to be opposite to the second clamping groove 11, the top post 12 is inserted into the second limiting groove 361 and forces the limiting post 56 to be separated from the second limiting groove 361; in this way, when the rainwater presses the first clamping groove 311 to be opposite to the second clamping groove 11 in a heavy rain day, the top post 12 is inserted into the second limiting groove 361, thereby the limiting post 56 is ejected to be separated from the fixing effect on the rack 52, the linear motor is started to drive the baffle 33 to rotate, so as to quickly drain water.

[0065] The implementation principle of the sports ground quick drainage system in the embodiment of the application is as follows: in a heavy rain day, rainwater is quickly collected above the drainage ditch 1, when the rainwater accumulates a certain amount, the weight of the rainwater moves the installation inner frame 3 towards the ditch bottom of the drainage ditch 1, during the movement of the installation inner frame 3, the pull rope 41 can pull the sliding plate 34 to move into the sliding groove 331, so as to increase the gap between the adjacent baffles 33 and improve the drainage speed of the rainwater; when the rainwater is too much to force the installation inner frame 3 to continue to move towards the ditch bottom of the drainage ditch 1, at this time, the first clamping groove 311 moves to the second clamping groove 11, the clamping post 61 is clamped in the second clamping groove 11 under the action of the first compression spring 62, thereby the relative position of the installation inner frame 3 is fixedly installed, at the same time, the top post 12 is inserted into the second limiting groove 361 to release the fixing effect of the limiting post 56 on the rack 52, the linear motor is started to drive the baffle 33 to rotate, thereby the gap between the adjacent baffles 33 is further enlarged, the drainage speed of the rainwater is accelerated, and the possibility of waterlogging caused by untimely drainage of the sports ground is reduced.

[0066] The above is the preferred embodiment of the application, which does not limit the protection scope of the application, therefore: all equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
