Description

Technical Field

[0001] The invention belongs to the technical field of garage flood prevention, and particularly relates to a two-way passable underground garage water blocking device. Background Art

[0002] Since the underground garage is built underground, in rainy weather, it is prone to the phenomenon of the underground garage being flooded, causing serious property losses. Traditional garages do not have perfect waterproof devices. Most of them are connected to the groundwater channel through ground covering grid plates. However, in the case of heavy rain, the flood prevention effect of these devices is limited;

[0003] Chinese invention patent CN110578319B discloses an underground garage waterproof device, which includes a water blocking system arranged at the garage entrance / exit. The water blocking plate water blocking system includes a drainage groove, a locking type driving device, a lifting type water blocking device and a grid plate cover. The drainage groove is arranged underground, the locking type driving device and the lifting type water blocking device are arranged in the drainage groove. The locking type driving device is connected to the water blocking plate in the lifting type water blocking device through a transmission component, and the grid plate cover is fixed at the notch of the drainage groove; the locking type driving device can use the gravity of the vehicle to drive the water blocking plate to make a lifting action, and the water blocking plate in the lifting type water blocking device is used to block the rainwater at the grid plate cover from entering the garage; through the vehicle gravity and mechanical structure, automatic operation is realized, and by installing two groups of water blocking plates to work intermittently, the water blocking effect is realized while ensuring the vehicle passage.

[0004] However, the water blocking plate in this waterproof device can only be driven to lift in one direction. When the vehicle needs to reverse (in the case of damage to the opposite road, the opposite water blocking plate cannot be lowered, etc.), the water blocking plate cannot be lowered, resulting in the vehicle being unable to pass.

[0058] Advantageous effects:

[0059] (1) A two-way passable underground garage water blocking device provided by the present invention does not limit the incoming direction of the vehicle. When a vehicle in the garage needs to borrow the opposite side channel (such as when the current channel is damaged, the water blocking plate of the water blocking device in the current channel cannot be lowered, etc.), the vehicle gravity can still make the water blocking plate of the water blocking device on the opposite side channel move downward, and the vehicle can borrow the opposite side channel to pass, improving the reliability of the water blocking device and the passing efficiency of the vehicle.

[0060] (2) In the present invention, two or more water blocking devices can be installed at intervals on each channel on the ramp to ensure effective drainage of water and prevent water from entering the garage interior.

[0061] (3) In the present invention, the telescopic drive assembly adopts a telescopic pen mechanism, uses the telescopic pen mechanism to realize the telescopic and locking of the rack, and the transmission assembly is a one-way transmission, which can realize that when the pressing plate is pressed by the front wheels of the vehicle, the water blocking plate rises or falls, and when the pressing plate is pressed by the rear wheels of the vehicle, the water blocking plate does not move, improving the passing efficiency of the vehicle.

[0062] (4) In the present invention, the one-way rotation limiting assembly includes a first limit member and a third elastic member, with a simple structure, and can also realize the one-way rotation of the rotating shaft I.

[0063] (5) The present invention is also provided with a fixing member, and the setting of the fixing member can increase the reliability of the one-way rotation of the rotating shaft I, thereby increasing the reliability of the lifting and lowering of the water blocking plate.

[0064] (6) The present invention is also provided with an isolation component, which is used to isolate the transmission between the drive shafts Ⅰ of the two drive components through the corresponding bevel gears Ⅰ and bevel gears Ⅱ, preventing mutual interference between the drive components on both sides of the water baffle.

[0065] (7) The present invention is also provided with an automatic control component for lifting the water baffle, which can move the water baffle downward to the lowest position when the water baffle device does not need to work, so as to improve the vehicle passing efficiency.

[0066] (8) The present invention is also provided with a cutting structure. When the water baffle device does not need to work, the management personnel make the cutting mechanism work through the controller, reducing the height of the pressing plate above the surface of the garage ramp. While generating the effect of a speed bump, it reduces the bumps generated when the vehicle passes, improves comfort, and reduces the loss of the transmission mechanism. When the water baffle device needs to work, the management personnel make the cutting mechanism stop working through the controller, restoring the power transmission between the pressing plate and the sliding cylinder Ⅱ.

[0101] The present invention will be described in detail below with reference to the accompanying drawings and by way of examples.

[0102] This embodiment provides a water - blocking device for an underground garage that can allow two - way passage, which is arranged on a slope. Refer to the attached Figure 1-4 , and the device includes a water - blocking plate 1, a pressing plate 2, a rotating cylinder 3, a sliding cylinder I 4, and a transmission assembly 5;

[0103] Two pressing plates 2 are respectively arranged on both sides of the water baffle 1. The pressing plates 2 and the water baffle 1 are both slidably connected to the slope along the up and down directions. And a first elastic member 72 is arranged between the pressing plate 2 and the slope for resetting the pressing plate 2.

[0104] The sliding cylinder I 4 is located inside the slope and is fixedly connected to the lower part of the water baffle 1. The top hole of the rotating cylinder 3 is in shaft fit with the inside of the sliding cylinder I 4.

[0105] See Appendix Figure 5 and Appendix Figure 6 As shown in Appendix and Appendix, a driving slider 41 is arranged on the inner wall of the sliding cylinder I 4. The outer wall of the rotating cylinder 3 is provided with a driving groove 31 that is connected end to end along the circumference. The driving groove 31 includes more than one wave crest and more than one wave valley. The driving slider 41 is located in the driving groove 31. And when the water baffle 1 is at the highest position, the driving slider 41 is at the wave crest. When the water baffle 1 is at the lowest position, the driving slider 41 is at the wave valley.

[0106] Each pressing plate 2 is driven by a transmission assembly 5 between it and the rotating cylinder 3.

[0107] When the pressing plate 2 is pressed down by the front wheel of the car, the pressing plate 2 drives the rotating cylinder 3 to rotate by an angle θ through the transmission assembly 5. The angle θ is the central angle between adjacent wave crest and wave valley of the driving groove 31. In a specific embodiment, θ is 180°.

[0108] When the pressing plate 2 is pressed down by the rear wheel of the car, the pressing plate 2 does not drive the rotating cylinder 3 to rotate through the transmission assembly.

[0109] A drain groove 73 is provided on the garage slope, and the drain groove 73 is arranged on the upper side of the water baffle 1.

[0110] The two-way passable underground garage water blocking device provided in this embodiment does not limit the incoming direction of the vehicle. When a car in the garage needs to borrow the opposite side channel (such as when the current channel is damaged, the water baffle 1 of the water blocking device in the current channel cannot be lowered, etc.), the gravity of the car can still make the water baffle 1 of the water blocking device on the opposite side channel move downward, and the car can borrow the opposite side channel to pass, improving the reliability of the water blocking device and the passing efficiency of the car.

[0111] Furthermore, more than two water blocking devices can be installed at intervals on each channel of the slope, and the drain grooves 73 are correspondingly arranged on the upper sides of the water baffles 1 of the corresponding water blocking devices. For example, two water blocking devices are installed at intervals on a one-way channel, and two water blocking devices are installed at intervals on each channel of a two-way channel, further reliably preventing water from entering the garage interior.

[0112] During the process of the vehicle entering the underground garage, the gravity of the front wheels of the vehicle causes the upper water baffle 1 to move to the lowest position. At this time, water may enter between two adjacent water baffles 1. As the vehicle continues to move, after the vehicle passes over the upper water baffle 1, the gravity of the front wheels of the vehicle causes the upper water baffle 1 to move to the highest position, continuing to block water. The water that enters between the two water baffles 1 enters the drainage groove 73 on the upper side of the next water baffle and is discharged through the drainage groove 73. As the vehicle continues to move, the gravity of the front wheels of the vehicle causes the lower water baffle 1 to move to the lowest position. As the vehicle continues to move, after the vehicle passes over the lower water baffle 1, the gravity of the front wheels of the vehicle causes the lower water baffle 1 to move to the highest position. To ensure that water can be effectively discharged and prevent water from entering the interior of the garage.

[0113] Further, vertical installation grooves 71 are provided on the garage ramp of the water baffle; the vertical installation grooves 71 are arranged at intervals along the long side direction of the water baffle pressing plate; the first elastic member 72 is arranged in the vertical installation groove 71, and the lower end of the first elastic member 72 abuts against the bottom surface of the vertical installation groove 71; the upper end of the first elastic member 72 abuts against the bottom surface of the pressing plate 2.

[0115] The telescopic drive assembly 51 adopts a telescopic pen mechanism. The upper end of the telescopic drive assembly is fixedly connected to the pressing plate 2. When the pressing plate 2 is pressed, the lower end of the telescopic drive assembly can be telescoped and locked;

[0116] The rack 52 is arranged at the lower end of the telescopic drive assembly. The rack 52 is driven by a gear set between the rotating shaft I 55; the bevel gear I 59 is arranged on the rotating shaft I 55, and a bevel gear II 32 is fixedly connected to the rotating cylinder 3. The bevel gear I 59 meshes with the bevel gear II 32;

[0117] During the process of the rack 52 extending downward and locking, the rotating shaft I 55 rotates forward, driving the bevel gear I 59 and the bevel gear II 32 to rotate;

[0118] The one-way rotation limiting assembly is arranged between the rotating shaft I 55 and the gear set. When the rack 52 retracts upward and locks, the one-way rotation limiting assembly restricts the reverse rotation of the rotating shaft I 55, and the bevel gear I 59 and the bevel gear II 32 do not move.

[0119] See Appendix Figure 9-11 The telescopic drive assembly 51 includes a fixed cylinder II 515, a sliding cylinder II 516, a rotating member 514, a transmission rod 512, a second elastic member 513 and a fixed cylinder I 511;

[0123] A second slope structure 5152 is arranged at each part of the lower end of the fixed cylinder II 515 between the shallow sliding groove 5153 and the deep sliding groove 5151;

[0124] The columnar structures I 5141 can extend into the deep sliding grooves 5151 of the fixed cylinder II 515 one by one, and the ends of the columnar structures I 5141 can extend into the shallow sliding grooves 5153 of the fixed cylinder II 515 one by one; the third slope structure 5162 of the sliding cylinder II can be in surface contact with the first slope structure at the upper end of the rotating member 514; the second slope structure 5152 of the fixed cylinder II 515 can also be in surface contact with the first slope structure at the upper end of the rotating member 514;

[0125] The fixed cylinder I 511 is fixed to the ramp and is coaxially located below the fixed cylinder II 515. The top end of the transmission rod 512 abuts against the lower end of the rotating member 514 through the connecting structure I 5121. The bottom end of the transmission rod 512 passes through the fixed cylinder I 511. The second elastic member 513 is coaxially sleeved on the outer circumference of the transmission rod 512, and the top end abuts against the connecting structure I 5121, and the bottom end abuts against the fixed cylinder II 515.

[0126] See attached Figure 7 and 8 Specifically, the gear set includes a first gear 54, a second gear 53 and a third gear 56;

[0127] The rack 52 is arranged at the lower end of the transmission rod 512. The second gear 53 is rotatably connected to the garage ramp. The first gear 54 is coaxially and fixedly connected to the second gear 53, and the first gear 54 meshes with the rack 52.

[0128] The rotating shaft I 55 is rotatably connected inside the garage ramp. The third gear 56 is in hole-shaft fit connection with one end of the rotating shaft I 55. The bevel gear I 59 is coaxially arranged at the other end of the rotating shaft I 55.

[0129] The third gear 56 meshes with the first gear 54. When the rack 52 reciprocates, it drives the first gear 54 and the second gear to rotate synchronously and bidirectionally, driving the third gear 56 to rotate bidirectionally.

[0130] See the appendix Figure 13 The one-way rotation limiting assembly includes a first limiting member 57 and a third elastic member 58.

[0131] A plurality of first limiting grooves 561 are arranged at intervals on the third gear 56. The first limiting grooves 561 are wedge-shaped. A first installation groove 551 is arranged on the rotating shaft I 55. The first limiting member 57 is slidably arranged in the first installation groove 551. One end of the first limiting member 57 is provided with a first limiting structure 571. The end of the first limiting structure 571 is wedge-shaped, and the first limiting structure 571 is fitted and abutted in one of the first limiting grooves 561. The third elastic member 58 is located at the other end of the first limiting member 57. One end of the third elastic member 58 abuts on the first limiting member 57, and the other end abuts on the side wall of the first installation groove 551.

[0132] When the water baffle 1 is at the highest or lowest position, the first limiting structure 571 is fitted and abutted in the corresponding first limiting groove 561.

[0133] The setting of the one-way rotation limiting assembly enables the third gear 56 and the rotating shaft I 55 to only rotate synchronously in one direction. For example, Figure 13 when the direction in the figure is the rotation direction of the third gear 56, the third gear 56 and the rotating shaft I 55 can rotate synchronously. When the third gear 56 rotates in the opposite direction, the wedge-shaped end of the first limiting structure 571 will disengage from the corresponding first limiting groove 561, and the third gear 56 and the rotating shaft I 55 cannot rotate synchronously.

[0134] Specifically, two first limiting grooves 561 are arranged on the third gear 56, and the two first limiting grooves 561 are spaced 180°.

[0135] Furthermore, see the appendix Figure 14 Each transmission assembly 5 further includes a fixing member 63.

[0136] The fixing member 63 is fixedly arranged on the garage ramp, and the rotating shaft I 55 is arranged through the fixing member 63; the outer wall of the rotating shaft I 55 is provided with third limiting grooves 553 with arc-shaped surfaces at intervals; the fixing member 63 is provided with a third installation groove 631; a sliding plate I 64 is slidably connected in the third installation groove 631; a third limiting member 65 is arranged at one end of the sliding plate I 64, and the third limiting member 65 is cooperatively abutted in one of the third limiting grooves 553; a fifth elastic member 66 is arranged at the other end of the sliding plate I 64; one end of the fifth elastic member 66 can be abutted against the bottom surface of the third installation groove 631; the other end of the fifth elastic member 66 is abutted against the sliding plate I 64.

[0137] When the third gear 56 and the rotating shaft I 55 rotate synchronously, under the rotation action of the rotating shaft I 55, the third limiting member 65 of the fixing member 63 disengages from the third limiting groove 553, enabling the rotating shaft I 55 to rotate smoothly in one direction; after the rotating shaft I 55 rotates in place, the third limiting member 65 enters another third limiting groove 553 under the elastic action of the fifth elastic member 66;

[0138] When the third gear 56 and the rotating shaft I 55 do not need to rotate synchronously, the third limiting member 65 of the fixing member 63 is clamped in the third limiting groove 553 to limit the rotation of the rotating shaft I 55;

[0139] The setting of the fixing member can increase the reliability of the one-way rotation of the rotating shaft I 55, thereby increasing the reliability of the lifting of the water baffle.

[0140] Further, referring to the appendix Figure 15 and 16 each transmission assembly 5 further includes an isolation assembly for isolating the transmission between the transmission shafts I 55 between two transmission assemblies 5 through the corresponding transmission between the bevel gear I 59 and the bevel gear II 32;

[0141] The isolation assembly includes a second limiting member 61 and a fourth elastic member 62;

[0142] The bevel gear I 59 is provided with second limiting grooves 591 at intervals, and the second limiting grooves 591 are wedge-shaped; the rotating shaft I 55 is provided with a second installation groove 552; a second limiting member 61 is slidably connected in the second installation groove 552; a second limiting structure 611 is arranged at one end of the second limiting member 61; the end of the second limiting structure 611 is wedge-shaped, and the second limiting structure 611 is cooperatively abutted in one of the second limiting grooves 591; the fourth elastic member 62 is arranged at the other end of the second limiting member 61; one end of the fourth elastic member 62 is abutted against the second limiting member 61; the other end of the second limiting member 61 is abutted against the wall surface of the second installation groove 552.

[0143] When the water baffle rises to the highest position and descends to the lowest position, all the second limiting structures 611 are abutted in the corresponding second limiting grooves 591;

[0144] Let the two sides of the water baffle be the first side and the second side respectively. When the rotating shaft Ⅰ 55 on the first side of the water baffle rotates, it drives the corresponding second limiting member 61 to rotate synchronously. At this time, the second limiting structure 611 abuts against the second limiting groove 591, driving the bevel gear Ⅰ 59 to rotate synchronously, driving the bevel gear Ⅱ 32 to rotate. The bevel gear Ⅱ 32 drives the bevel gear Ⅰ 59 on the second side of the water baffle to rotate. At this time, the rotation directions of the bevel gears Ⅰ 59 on both sides of the water baffle are opposite. Under the limiting action of the second side fixing member, the second limiting member 61 in the rotating shaft Ⅰ 55 on the second side of the water baffle disengages from the second limiting groove 59 under the action of the wedge-shaped second limiting groove 59, so that the rotating shaft Ⅰ 55 on the second side of the water baffle does not rotate.

[0145] Working principle of the water retaining device:

[0146] During operation, when the front wheel of the vehicle presses on a pressing plate 2 on one side of the water baffle 1, the gravity of the vehicle resists the elastic force of the first elastic member 72, driving the pressing plate 2 to move downward, and driving the rotating cylinder 3 to rotate through the transmission assembly 5. When the rotating cylinder 3 rotates, the side wall of the driving groove 31 generates a thrust on the driving slider 41, driving the driving slider 41 to move downward, driving the sliding cylinder Ⅰ 4 to move downward, and further driving the water baffle 1 to move downward. When the rotating cylinder 3 rotates by an angle θ, the driving slider 41 moves to the trough of the two driving grooves 31. At this time, the water baffle 1 moves to the lowest position. And when the pressing plate 2 is pressed down by the rear wheel of the vehicle, the pressing plate 2 does not drive the rotating cylinder 3 to rotate through the transmission assembly, and the water baffle 1 remains at the lowest position, facilitating the vehicle to pass over the water baffle 1.

[0147] When the vehicle completely crosses the water baffle 1 and the front wheel presses on a pressing plate 2 on the other side of the water baffle 1, the gravity of the vehicle resists the elastic force of the first elastic member 72, driving the pressing plate 2 to move downward, and driving the rotating cylinder 3 to rotate again through the transmission assembly 5. When the rotating cylinder 3 rotates, the side wall of the driving groove 31 generates a thrust on the driving slider 41, driving the driving slider 41 to move upward, driving the sliding cylinder Ⅰ 4 to move upward, driving the water baffle 1 to move upward. When the rotating cylinder 3 rotates by an angle θ, the driving slider 41 moves to the peak of the two driving grooves 31. At this time, the water baffle 1 moves to the highest position.

[0148] Transmission principle of the transmission assembly 5:

[0149] Taking the vehicle passing through a pressing plate 2 on one side of the water baffle 1 and lowering the water baffle 1 from the highest position to the lowest position as an example:

[0150] In the initial state, the columnar structure I 5141 of the rotating member 514 is located in the deep sliding groove 5151 of the fixed cylinder II 515, the first limiting structure 571 of the one-way rotation limiting assembly is located in a first limiting groove 561, and the driving slider 41 is located at the peak of the driving groove 31;

[0151] When the front wheel of the vehicle presses on the pressing plate 2, it resists the elastic force of the first elastic member 72 and causes the pressing plate 2 to move downward. When the pressing plate 2 moves downward, it drives the columnar structure II 5161 of the sliding cylinder II 516 to move downward, so that the third slope structure 5162 of the columnar structure II 5161 abuts against the first slope structure of the columnar structure I 5141 of the rotating member 514, and pushes the rotating member 514 downward; on the one hand, the transmission rod 512 moves downward under the push of the rotating member 514, drives the rack 52 to move downward, the first gear 54 meshing with the rack 52 rotates, drives the second gear 53 to rotate synchronously, the third gear 56 meshing with the second gear 53 rotates, and the third gear 56 drives the rotating shaft I 55 to rotate synchronously under the limitation of the one-way rotation limiting assembly, drives the bevel gear I 59 at the other end of the rotating shaft I 55 to rotate synchronously, drives the bevel gear II 32 meshing with the bevel gear I 59 to rotate, and drives the rotating cylinder 3 to rotate; when the rotating cylinder 3 rotates, the side wall of the driving groove 31 generates a thrust on the driving slider 41, drives the driving slider 41 to move downward, drives the sliding cylinder I 4 to move downward, and further drives the water blocking plate 1 to move downward. When the rotating cylinder 3 rotates by an angle θ (at this time, the first limiting structure 571 of the one-way rotation limiting assembly is located in a first limiting groove 561), the driving slider 41 moves to the trough of the driving groove 31, and at this time the water blocking plate 1 moves to the lowest position. On the other hand, the first slope structure of the rotating member 514 moves downward. When the first slope structure disengages from the deep sliding groove 5151, the rotating member 514 rotates under the action of the horizontal component force of the third slope structure 5162 on the first slope structure and the elastic force of the second elastic member 513, so that the first slope structure abuts against the second slope structure 5152, and at this time the rack 52 disengages from the engagement with the first gear 54;

[0152] When the front wheel of the vehicle leaves the pressing plate 2, the elastic force of the first elastic member 72 causes the pressing plate 2 to move upward, drives the sliding cylinder II 516 and its third slope structure 5162 to move upward, and the rotating member 514 rotates under the action of the horizontal component force of the second slope structure 5152 on the first slope structure and the elastic force of the second elastic member 513, so that the first slope enters the adjacent shallow sliding groove 5153 along the second slope structure 5152 and moves upward in the shallow sliding groove 5153 until it abuts against the wall surface of the shallow sliding groove 5153. At this time, the rotating member 514 is locked, and the rack 52 still disengages from the engagement with the first gear 54;

[0153] When the rear wheel of the vehicle presses on the pressing plate 2, it resists the elastic force of the first elastic member 72 and causes the pressing plate 2 to move downward. When the pressing plate 2 moves downward, it drives the columnar structure Ⅱ5161 of the sliding cylinder Ⅱ516 to move downward, so that the third slope structure 5162 of the columnar structure Ⅱ5161 abuts against the first slope structure of the columnar structure Ⅰ5141 of the rotating member 514, and pushes the rotating member 514 to move downward. Since the rack 52 and the first gear 54 are not engaged at this time, the first gear 54 does not rotate; the first slope structure of the rotating member 514 moves downward and compresses the second elastic member 513. When the first slope structure disengages from the shallow sliding groove 5153, the rotating member 514 rotates under the combined action of the horizontal component force of the third slope structure 5162 on the first slope structure and the elastic force of the second elastic member 513. When the pressing plate 2 moves to the lowest position, the first slope structure moves below the second slope structure 5152;

[0154] When the rear wheel of the vehicle leaves the pressing plate 2, under the action of the horizontal component force of the second slope structure 5152 on the first slope structure and the elastic force of the second elastic member 513, the first slope structure enters the adjacent deep sliding groove 5151 along the second slope structure 5152, and the rotating member 514 and the transmission rod 512 move upward. The rack 52 contacts and engages with the first gear 54, driving the first gear 54 to rotate, driving the second gear 53 to rotate, and driving the third gear 56 to rotate. However, due to the setting of the one-way rotation limiting component, the wedge-shaped first limiting groove 561 and the wedge-shaped first limiting structure 571 interact with each other, pushing the first limiting structure 571 out of the first limiting groove 561, and the rotating shaft Ⅰ55 does not rotate synchronously with the third gear 56, so the bevel gear Ⅰ59, the bevel gear Ⅱ32, and the rotating cylinder 3 do not rotate.

[0163] Two sliding plates II 81 are symmetrically arranged on both sides of the pressing plate 2, and the sliding plates II 81 are slidably connected to the garage ramp; two connecting structures II 811 are provided on the side of the sliding plate II 81 connected to the pressing plate 2; a fifth installation groove 8111 is provided on each connecting structure II 811; the fifth limiting members 82 are slidably arranged in the fifth installation grooves 8111 one by one. A fourth limiting structure 821 is provided at one end of the fifth limiting member 82; a seventh elastic member 83 is provided at the other end of the fifth limiting member 82; one end of the seventh elastic member 83 abuts against the fifth limiting member 82; the other end of the seventh elastic member 83 abuts against the wall surface of the fifth installation groove 8111;

[0164] The transverse sides of the sliding groove Y211 of the bottom plate 21 are open. The sliding structure of the support plate 23 is provided with a plug-in groove 2311, and fifth limiting grooves 2312 are provided on the two side walls of the plug-in groove 2311;

[0165] The connection structure II 811 on each side of the sliding plate II 81 can extend into the side opening of the corresponding side sliding groove Y211 and into the plug-in groove 2311. The fourth limiting structure 821 of the fifth limiting member 82 in the connection structure II 811 can enter the fifth limiting groove 2312 one by one under the action of the seventh elastic member 83;

[0166] The cutting drive assembly 84 is connected to the sliding plate II 81 and is used to drive the two sliding plates II 81 to approach or move away from each other;

[0167] The cutting drive assembly 84 includes a threaded shaft 841, a drive shaft 842, a transmission member 843, and a motor X844; the threaded shaft 841 is in threaded connection with the sliding plate II 81, and the threaded shaft 841 is rotatably connected to the garage ramp; the motor X844 is fixedly arranged in the ramp, the drive shaft 842 is fixedly connected to the output shaft of the motor X844, and the drive shaft 842 and the threaded shaft 841 are connected and driven through the transmission member 843.

[0168] The automatic lifting principle of the water baffle 1:

[0169] When the water blocking device is not required to work, the management personnel make the cutting mechanism 8 work through the controller. The cutting mechanism 8 disconnects the power transmission between the pressing plate 2 and the sliding cylinder II 516, so that the sliding cylinder II 516 remains stationary; at the same time, the management personnel make the corner motor 34 work through the controller, so that the rotating shaft of the corner motor 34 rotates forward (such as Figure 17 the arrow direction in the figure), driving the fourth limiting member 352 to rotate along with the rotating shaft II 35. At this time, the third limiting structure 3521 abuts against the fourth limiting groove 33, and drives the rotating cylinder 3 to rotate forward through the third limiting structure 3521, so that the rotating cylinder 3 rotates forward by an angle θ, so that the driving slider 41 moves down to the lowest position, and the water baffle 1 moves down to the lowest position to improve the vehicle passing efficiency.

[0170] When the water retaining device needs to work (the management personnel judge whether the water retaining device needs to work according to the weather conditions or the actual rainfall conditions), the management personnel make the cutting mechanism 8 stop working through the controller, and resume the power transmission between the pressing plate 2 and the sliding cylinder II 516. At the same time, the management personnel make the corner motor 34 work through the controller, make the rotating shaft of the corner motor 34 rotate forward by an angle θ, drive the rotating shaft II 35 to rotate forward, drive the fourth limiting member 352 to rotate along with the rotating shaft II 35. At this time, the third limiting structure 3521 abuts against the fourth limiting groove 33 and drives the rotating cylinder 3 to rotate forward through the third limiting structure 3521, so that the rotating cylinder 3 rotates forward by an angle θ, and the driving slider 41 moves upward to the highest position to block the water. At this time, when the wheel presses the pressing plate 2 and the transmission assembly 5 drives the rotating cylinder 3 to rotate (as shown by the arrow direction in Figure 17 ), the side wall of the fourth limiting groove 33 generates a thrust on the third limiting structure 3521, overcomes the elastic force of the sixth elastic member 353, and makes the third limiting structure 3521 disengage from the fourth limiting groove 33, so that the rotating cylinder 3 forms a rotating connection with the rotating shaft II 35, ensuring the reliable rotation of the rotating cylinder 3.

[0171] Furthermore, a seal I 91 and a seal II 92 are fixedly connected to the garage slope; the seal I 91 is used to seal the gap between the side wall of the top plate 22 and the garage slope; the seal II 92 is used to seal the gap between the side wall of the water retaining plate 1 and the garage slope.

[0172] By sealing the gap between the side wall of the top plate 22 and the garage slope with the seal I 91, the probability of water flowing downward along the side wall of the top plate 22 is reduced, the probability of rusting of the support plate 23, the bottom plate 21, etc. is reduced, and at the same time, the probability of water entering the interior of the garage slope along the side wall of the top plate 22 is reduced, and the probability of damage to the garage slope is reduced;

[0173] By sealing the gap between the side wall of the water retaining plate 1 and the garage slope with the seal II 92, the probability of water flowing downward along the side wall of the water retaining plate 1 is reduced, the probability of rusting of the rotating cylinder 3, the bevel gear II 32, etc. is reduced, and at the same time, the probability of water entering the interior of the garage slope along the side wall of the water retaining plate 1 is reduced, and the probability of damage to the garage slope is reduced.

[0174] Cutting principle of the cutting mechanism 8:

[0175] When the water retaining device does not need to work, the management personnel make the cutting drive assembly 84 work through the controller. The cutting drive assembly 84 drives two sliding plates II 81 to approach each other, so that the sliding plates II 81 extend into the sliding groove Y211, prevent the bottom plate 21 from generating vertical sliding, and disconnect the power transmission between the bottom plate 21 and the sliding cylinder II 516;

[0176] When the water retaining device needs to work, the manager operates the controller to activate the cutting drive assembly 84. The cutting drive assembly 84 drives the two sliding plates II 81 to move away from each other, causing the ends of the sliding plates II 81 to disengage from the sliding slots Y211, restoring the sliding state of the bottom plate 21, and restoring the power transmission between the bottom plate 21 and the sliding cylinder II 516.

[0177] When the two sliding plates II 81 move closer to each other, the connecting structure II 811 of the sliding plate II 81 first extends into the sliding slot Y211, and then into the insertion slot 2311 of the support plate 23 until the fourth limiting structure 821 of the fifth limiting member 82 in the connecting structure II 811 abuts against the sliding structure 231 of the support plate 23 (i.e., both sides of the insertion slot 2311). The sliding plate II 81 continues to move, generating a thrust on the sliding structure 231, driving the two support plates 23 to move closer to each other. When the two support plates 23 abut against each other, the elastic force of the seventh elastic member 83 causes the fourth limiting structure 821 to abut against the fifth limiting slot 2312. At this time, the top plate 22 moves downward under the action of gravity. The top of the support plate 23 enters the through slot of the top plate, and the support structure 221 abuts against the bottom plate 21. While cutting off the power transmission between the bottom plate 21 and the sliding cylinder II 516, the height of the top plate 22 above the surface of the garage ramp can be reduced. While generating the effect of a speed bump, the jolts generated when the vehicle passes can be reduced, improving comfort.

[0178] When the two sliding plates II 81 move away from each other, they drive the fourth limiting structure 821 to move. Since the fourth limiting structure 821 abuts against the fifth limiting slot 2312, the fourth limiting structure 821 drives the sliding structure 231 to move, causing the two support plates 23 to move away from each other (when the distance between the two support plates 23 is the largest, the fourth limiting structure 821 disengages from the fifth limiting slot 2312). Under the action of the inclined plane of the through slot of the top plate 22, the support plate 23 moves to the lower end of the support structure 221, increasing the distance between the top plate 22 and the bottom plate 21. When the wheel drives the top plate 22 to move downward, it drives the support plate 23 and the bottom plate 21 to move downward, driving the water retaining plate 1 to move, ensuring that the vehicle can pass while blocking water.

[0179] Control principle of the cutting drive assembly 84:

[0180] When the water retaining device does not need to work, the manager operates the controller to activate the motor X844, causing the rotating shaft of the motor X844 to rotate forward. Through the transmission member 843, the threaded shaft 841 is driven to rotate, driving the two sliding plates II 81 to move closer to each other, causing the sliding plates II 81 to abut against the sliding slots Y211, preventing the bottom plate 21 from sliding vertically, and fixing the bottom plate 21.

[0181] When the water retaining device needs to work, the manager operates the motor X844 through the controller, causing the rotating shaft of the motor X844 to rotate in the reverse direction. The threaded shaft 841 is driven to rotate in the reverse direction through the transmission member 843, driving the two sliding plates II 81 to move away from each other, so that the end of the sliding plate II 81 disengages from the sliding groove Y211, releasing the fixation of the bottom plate 21.

[0182] In summary, the above are only the preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
