Description

A water-blocking device for a two-way passage underground parking garage Technical Field

[0001] This invention belongs to the field of garage flood control technology, specifically relating to a water-blocking device for an underground garage that allows bidirectional passage. Background Technology

[0002] Because underground parking garages are built underground, they are prone to flooding during heavy rain, causing serious property damage. Traditional parking garages do not have a complete waterproofing system and most of them are connected to underground waterways by ground-covered gratings. However, these systems have limited flood protection capabilities during heavy rain.

[0003] Chinese invention patent CN110578319B discloses a waterproofing device for an underground garage, including a water-blocking system installed at the garage entrance / exit. The water-blocking system includes a drainage channel, a locking drive device, a lifting water-blocking device, and a grating cover. The drainage channel is located underground, and the locking drive device and the lifting water-blocking device are installed inside the drainage channel. The locking drive device is connected to the water-blocking plate in the lifting water-blocking device through a transmission component, and the grating cover is fixed at the opening of the drainage channel. The locking drive device can use the weight of the vehicle to drive the water-blocking plate to move up and down. The water-blocking plate in the lifting water-blocking device is used to prevent rainwater from entering the garage through the grating cover. The device achieves automated operation through vehicle weight and mechanical structure. By installing two sets of water-blocking plates that work intermittently, it can achieve the function of blocking water while ensuring vehicle passage.

[0004] However, the water deflector in this waterproofing device can only be raised and lowered in one direction. When a vehicle needs to travel in the opposite direction (due to damage to the road on the other side, the water deflector on the other side being unable to lower, etc.), the water deflector cannot be lowered, making it impossible for the vehicle to pass. Summary of the Invention

[0005] In view of this, the present invention provides a water-blocking device for underground parking garages that allows two-way traffic, thereby improving the traffic efficiency of underground parking garage exits.

[0058] Beneficial effects:

[0059] (1) The present invention provides a water barrier device for underground garages that allows bidirectional passage. It does not restrict the direction of vehicle travel. When a car in the garage needs to use the opposite passage (such as when the current passage is damaged or the water barrier of the current passage cannot be lowered), the car's weight can still cause the water barrier of the opposite passage to move downward, allowing the car to use the opposite passage for passage, thereby improving the reliability of the water barrier device and the passage efficiency of the car.

[0060] (2) In this invention, two or more water-blocking devices can be installed at intervals on each passage on the slope to ensure that water can be effectively discharged and prevent water from entering the garage.

[0061] (3) In this invention, the telescopic drive component adopts a telescopic pen mechanism to realize the extension and locking of the rack and pinion. The transmission component is unidirectional, which can realize that when the pressure plate is pressed down by the front wheel of the car, the water deflector rises or falls, and when the pressure plate is pressed down by the rear wheel of the car, the water deflector does not move, thus improving the traffic efficiency of the car.

[0062] (4) The unidirectional rotation limiting component in this invention includes a first limiting member and a third elastic member. It has a simple structure and can also realize the unidirectional rotation of the rotating shaft I.

[0063] (5) The present invention is also provided with a fixing component, which can increase the reliability of the unidirectional rotation of the rotating shaft I, thereby increasing the reliability of the water baffle lifting.

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

[0065] (7) The present invention is also provided with an automatic control component for raising and lowering the water deflector, which can move the water deflector down to the lowest position when the water deflector is not required to work, so as to improve the efficiency of vehicle traffic.

[0066] (8) The present invention also includes a cutting structure. When the water-blocking device is not required, the operator can activate the cutting mechanism via the controller to lower the height of the pressure plate above the garage ramp surface. This creates a speed bump effect while reducing the bumps caused by vehicles passing over it, improving comfort, and reducing the wear and tear on the transmission mechanism. When the water-blocking device is required, the operator can activate the cutting mechanism via the controller to stop the operation and restore the power transmission between the pressure plate and the sliding cylinder II.

[0100] 91-Seal I, 92-Seal II. Detailed Implementation

[0101] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0102] This embodiment provides a water-blocking device for a bidirectional underground garage, which is installed on a slope. See Figures 1-4. The device includes a water-blocking plate 1, a pressure plate 2, a rotating cylinder 3, a sliding cylinder I 4, and a transmission assembly 5.

[0103] Two pressure plates 2 are respectively set on both sides of the baffle plate 1. Both the pressure plate 2 and the baffle plate 1 are slidably connected to the ramp edge; and a first elastic element 72 is provided between the pressure plate 2 and the ramp for the pressure plate 2 to be reset.

[0104] The sliding cylinder I4 is located inside the slope and is fixedly connected to the bottom of the baffle plate 1. The top hole of the rotating cylinder 3 is fitted into the sliding cylinder I4.

[0105] Referring to Figures 5 and 6, the inner wall of the sliding cylinder I4 is provided with a driving slider 41, and the outer wall of the rotating cylinder 3 is provided with a driving groove 31 connected end to end along the circumference. The driving groove 31 includes one or more crests and one or more troughs. The driving slider 41 is located inside the driving groove 31. When the baffle plate 1 is at its highest position, the driving slider 41 is located at the crest; when the baffle plate 1 is at its lowest position, the driving slider 41 is located at the trough.

[0106] Each pressure plate 2 is connected to the rotating cylinder 3 via a transmission assembly 5;

[0107] When the pressure plate 2 is pressed down by the front wheel of the car, the pressure 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 crests and troughs of the drive groove 31; in a specific embodiment, θ is 180°.

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

[0109] A drainage channel 73 is provided on the garage slope, and the drainage channel 73 is located on the upper side of the water baffle 1.

[0110] This embodiment provides a bidirectional water barrier device for underground parking garages that does not restrict the direction of vehicle travel. When a car in the garage needs to use the opposite passage (e.g., if the current passage is damaged or the water barrier 1 of the current passage cannot be lowered), the car's weight can still cause the water barrier 1 of the opposite passage to move downwards, allowing the car to use the opposite passage for passage, thus improving the reliability of the water barrier device and the efficiency of vehicle passage.

[0111] Furthermore, two or more water-blocking devices can be installed at intervals on each passage of the slope, and drainage channels 73 are set one-to-one on the upper side of the water-blocking plate 1 of the corresponding water-blocking device; for example, two water-blocking devices are installed at intervals on a one-way passage, and two water-blocking devices are installed at intervals on each passage of a two-way passage, so as to further reliably prevent water from entering the garage.

[0112] As the car enters the underground parking garage, the weight of its front wheels causes the upper flood barrier 1 to move to its lowest position. At this point, water may enter between two adjacent flood barriers 1. As the car continues to move and passes the upper flood barrier 1, the weight of its front wheels causes the upper flood barrier 1 to move to its highest position, continuing to block the water. Water that has entered between two flood barriers 1 flows into the drainage channel 73 located above the next flood barrier 1 and is discharged through the drainage channel 73. As the car continues to move, the weight of its front wheels causes the lower flood barrier 1 to move to its lowest position. As the car continues to move and passes the lower flood barrier 1, the weight of its front wheels causes the lower flood barrier 1 to move to its highest position. This ensures that water can be effectively discharged and prevents water from entering the garage.

[0113] Furthermore, a vertical mounting groove 71 is provided on the slope of the water-retaining garage; the vertical mounting groove 71 is spaced apart along the long side of the water-retaining pressure plate; a first elastic member 72 is provided in the vertical mounting groove 71, the lower end of the first elastic member 72 abuts against the bottom surface of the vertical mounting groove 71; the upper end of the first elastic member 72 abuts against the bottom surface of the pressure plate 2.

[0114] Referring to Figures 1, 2, 7 and 8, each transmission assembly 5 includes a telescopic drive assembly 51, a rack 52, a gear set, a rotating shaft I 55, a bevel gear I 59 and a one-way rotation limit assembly;

[0115] The telescopic drive assembly 51 adopts a telescopic pen mechanism. The upper end of the telescopic drive assembly is fixedly connected to the pressure plate 2. When the pressure plate 2 is pressed, the lower end of the telescopic drive assembly can extend and lock.

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

[0117] During the downward extension and locking of rack 52, rotating shaft I 55 rotates in the forward direction, driving bevel gear I 59 and bevel gear II 32 to rotate.

[0118] A one-way rotation limit component is set between the rotating shaft I 55 and the gear set. When the rack 52 retracts upward and locks, the one-way rotation limit component restricts the rotating shaft I 55 from rotating in the opposite direction, and the bevel gear I 59 and bevel gear II 32 remain stationary.

[0119] Referring to Figures 9-11, the telescopic drive assembly 51 includes a fixed cylinder II 515, a sliding cylinder II 516, a rotating component 514, a transmission rod 512, a second elastic component 513, and a fixed cylinder I 511;

The guide block extends out of the guide groove 5163 and is fixed to the garage slope. The guide block 5155 can slide up and down along the guide groove 5163, so that sliding cylinder II can slide up and down relative to fixed cylinder II 515 without rotating.

[0121] The bottom end of the sliding cylinder II is provided with a plurality of columnar structures II5161 evenly spaced; the lower end of each columnar structure II5161 is provided with a third inclined structure 5162; the side wall of the fixed cylinder II515 is evenly provided with a plurality of deep sliding grooves 5151 and a plurality of shallow sliding grooves 5153, the deep sliding grooves 5151 and the shallow sliding grooves 5153 are alternately arranged; at least one columnar structure II5161 and a deep sliding groove 5151 are located at the same central angle, and at least one columnar structure II5161 and a shallow sliding groove 5153 are located at the same central angle.

[0122] The rotating component 514 is coaxially located below the sliding cylinder II. The rotating component 514 is provided with columnar structures I 5141 evenly spaced on it, and the upper end of the columnar structure I 5141 is provided with a first inclined structure.

[0123] The lower end of the fixed cylinder II 515 is provided with a second ramp structure 5152 in each portion located between the shallow sliding groove 5153 and the deep sliding groove 5151;

[0124] The columnar structure I 5141 can be inserted into the deep sliding groove 5151 of the fixed cylinder II 515, and the ends of the columnar structure I 5141 can be inserted into the shallow sliding groove 5153 of the fixed cylinder II 515. The third slope structure 5162 of the sliding cylinder II can contact the first slope structure surface at the upper end of the rotating part 514. The second slope structure 5152 of the fixed cylinder II 515 can also contact the first slope structure surface at the upper end of the rotating part 514.

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

[0126] Referring to Figures 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 located 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 fixedly connected to the second gear 53, and the first gear 54 meshes with the rack 52;

[0128] Rotary shaft I55 is rotatably connected to the garage ramp. The third gear 56 is connected to the shaft hole at one end of rotary shaft I55. The bevel gear I59 is coaxially set at the other end of rotary shaft I55.

[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 in both directions, and drives the third gear 56 to rotate in both directions.

[0130] Referring to Figure 13, the unidirectional rotation limiting assembly includes a first limiting member 57 and a third elastic member 58;

[0131] The third gear 56 is provided with a plurality of first limiting grooves 561 spaced apart, and the first limiting grooves 561 are wedge-shaped; the rotating shaft I 55 is provided with a first mounting groove 551; the first limiting member 57 is slidably disposed in the first mounting groove 551, and 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 abuts against 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 against the first limiting member 57, and the other end abuts against the side wall of the first mounting groove 551;

[0132] When the baffle plate 1 is at its highest or lowest position, the first limiting structure 571 is engaged in abutting against the corresponding first limiting groove 561.

[0133] The unidirectional rotation limiting component ensures that the third gear 56 and the rotating shaft I 55 can only rotate synchronously in one direction. When the direction shown in Figure 13 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 will not be able to rotate synchronously.

[0134] Specifically, the third gear 56 is provided with two first limiting grooves 561, which are spaced 180° apart.

[0135] Furthermore, referring to Figure 14, each transmission assembly 5 also includes a fixing member 63;

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

[0137] When the third gear 56 and the rotating shaft I 55 rotate synchronously, the third limiting member 65 of the fixing member 63 disengages from the third limiting groove 553 under the rotation action of the rotating shaft I 55, so that the rotating shaft I 55 can rotate smoothly in one direction; after the rotating shaft I 55 rotates to the position, 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 locked in the third limiting groove 553 to limit the rotation of the rotating shaft I 55.

[0139] The installation of the fixing component can increase the reliability of the unidirectional rotation of the rotating shaft I55, thereby increasing the reliability of the water baffle lifting and lowering.

[0140] Furthermore, referring to Figures 15 and 16, each transmission assembly 5 also includes an isolation assembly for isolating the transmission between the transmission shafts I 55 of the two transmission assemblies 5 via the corresponding bevel gears I 59 and II 32;

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

[0142] The bevel gear I59 is provided with a second limiting groove 591 at intervals, and the second limiting groove 591 is wedge-shaped; the rotating shaft I55 is provided with a second mounting groove 552; a second limiting member 61 is slidably connected in the second mounting groove 552; a second limiting structure 61 is provided 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 abuts against one of the second limiting grooves 591; a fourth elastic member 62 is provided at the other end of the second limiting member 61; one end of the fourth elastic member 62 abuts against the second limiting member 61; the other end of the second limiting member 61 abuts against the wall surface of the second mounting groove 552.

[0143] When the baffle plate is raised to the highest position and lowered to the lowest position, all the second limiting structures 611 abut against the corresponding second limiting grooves 591;

[0144] Let the two sides of the baffle be the first side and the second side, respectively. When the rotating shaft I55 on the first side of the 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 I59 to rotate synchronously, driving the bevel gear II32 to rotate. The bevel gear II32 drives the bevel gear I59 on the second side of the baffle to rotate. At this time, the bevel gears I59 on both sides of the baffle rotate in opposite directions. Under the limiting action of the second side fixing member, the second limiting member 61 in the rotating shaft I55 on the second side of the baffle is disengaged from the second limiting groove 59 under the action of the wedge-shaped second limiting groove 59, so that the rotating shaft I55 on the second side of the baffle does not rotate.

[0145] Working principle of water blocking device:

[0146] During operation, when the front wheels of the car press on a pressure plate 2 on one side of the baffle 1, the car's weight resists the elastic force of the first elastic element 72, causing the pressure plate 2 to move downwards. This movement is then transmitted through the transmission assembly 5 to the rotating cylinder 3. As the rotating cylinder 3 rotates, the side wall of the drive groove 31 exerts a thrust on the drive slider 41, causing the drive slider 41 to move downwards. This, in turn, causes the sliding cylinder 1 4 to move downwards, which in turn causes the baffle 1 to move downwards. When the rotating cylinder 3 rotates at an angle θ, the drive slider 41 moves to the trough of the two drive grooves 31. At this point, the baffle 1 is at its lowest position. Furthermore, when the pressure plate 2 is pressed down by the rear wheels of the car, the pressure plate 2 does not drive the rotating cylinder 3 to rotate through the transmission assembly, and the baffle 1 remains at its lowest position, allowing the car to pass over the baffle 1.

[0147] When the car completely passes over the floodgate 1 and the front wheels press on a pressure plate 2 on the other side of the floodgate 1, the car's gravity resists the elastic force of the first elastic element 72, causing the pressure plate 2 to move downwards. This movement is then transmitted through the transmission assembly 5 to the rotating cylinder 3, which rotates again. As the rotating cylinder 3 rotates, the side wall of the drive groove 31 exerts a thrust on the drive slider 41, causing the drive slider 41 to move upwards. This, in turn, causes the sliding cylinder 1 4 to move upwards, and the floodgate 1 to move upwards. When the rotating cylinder 3 rotates by an angle θ, the drive slider 41 moves to the crest of the two drive grooves 31, at which point the floodgate 1 moves to its highest position.

[0148] Transmission component 5: Transmission principle:

[0149] Taking the example of a car passing over a pressure plate 2 on one side of the water deflector 1, causing the water deflector 1 to descend from its highest position to its lowest position:

[0150] In the initial state, the columnar structure Ⅰ5141 of the rotating component 514 is located in the deep sliding groove 5151 of the fixed cylinder Ⅱ515, the first limiting structure 571 of the unidirectional rotation limiting assembly is located in a first limiting groove 561, and the driving slider 41 is located at the crest of the driving groove 31.

[0151] When the front wheels of the car press on the pressure plate 2, they resist the elastic force of the first elastic element 72, causing the pressure plate 2 to move downwards. As the pressure plate 2 moves downwards, it drives the columnar structure II 5161 of the sliding cylinder II 516 to move downwards, causing the third ramp structure 5162 of the columnar structure II 5161 to abut against the first ramp structure of the columnar structure I 5141 of the rotating element 514, pushing the rotating element 514 downwards. Simultaneously, the transmission rod 512 moves downwards under the push of the rotating element 514, driving the rack 52 downwards. The first gear 54, meshing with the rack 52, rotates, driving the second gear 53 to rotate synchronously. The third gear 56, meshing with the second gear 53, rotates. The third gear 56... Under the limiting position of the one-way rotation limiting component, the rotating shaft I55 rotates synchronously, which in turn drives the bevel gear I59 at the other end of the rotating shaft I55 to rotate synchronously, which in turn drives the bevel gear II32 meshing with the bevel gear I59 to rotate, which in turn drives the rotating cylinder 3 to rotate. When the rotating cylinder 3 rotates, the side wall of the drive groove 31 generates a thrust on the drive slider 41, which drives the drive slider 41 to move downward, which in turn drives the sliding cylinder I4 to move downward, which in turn drives the baffle plate 1 to move downward. The rotating cylinder 3 rotates by an angle θ (at this time, the first limiting structure 571 of the one-way rotation limiting component is located in a first limiting groove 561), and the drive slider 41 moves to the trough of the drive groove 31. At this time, the baffle plate 1 moves to the lowest position. On the other hand, the first ramp structure of the rotating member 514 moves downward. When the first ramp structure disengages from the deep sliding groove 5151, the rotating member 514 rotates under the action of the horizontal component force of the third ramp structure 5162 on the first ramp structure and the elastic force of the second elastic member 513, causing the first ramp structure to collide with the second ramp structure 5152. At this time, the rack 52 disengages from the first gear 54.

[0152] When the front wheels of the car leave the pressure plate 2, the elastic force of the first elastic element 72 causes the pressure plate 2 to move upward, which in turn drives the sliding cylinder II 516 and its third ramp structure 5162 to move upward. The rotating element 514 rotates under the action of the horizontal component of the second ramp structure 5152 on the first ramp structure and the elastic force of the second elastic element 513, causing the first ramp to enter the adjacent shallow sliding groove 5153 along the second ramp structure 5152 and move upward in the shallow sliding groove 5153 until it abuts against the wall of the shallow sliding groove 5153. At this time, the rotating element 514 is locked, and the rack 52 is still disengaged from the first gear 54.

[0153] When the rear wheel of the car presses on the pressure plate 2, it resists the elastic force of the first elastic element 72, causing the pressure plate 2 to move downward. When the pressure plate 2 moves downward, it drives the columnar structure II 5161 of the sliding cylinder II 516 to move downward, causing the third ramp structure 5162 of the columnar structure II 5161 to abut against the first ramp structure of the columnar structure I 5141 of the rotating element 514, pushing the rotating element 514 to move downward. Since the rack 52 and the first gear 54 are not meshed at this time, the first gear 54 does not rotate. The first ramp structure of the rotating element 514 moves downward and compresses the second elastic element 513. When the first ramp structure disengages from the shallow sliding groove 5153, the rotating element 514 rotates under the combined action of the horizontal component force of the third ramp structure 5162 on the first ramp structure and the elastic force of the second elastic element 513. When the pressure plate 2 moves to the lowest position, the first ramp structure moves below the second ramp structure 5152.

[0154] When the rear wheel of the car leaves the pressure plate 2, under the action of the horizontal component force of the second ramp structure 5152 on the first ramp structure and the elastic force of the second elastic member 513, the first ramp structure enters the adjacent deep sliding groove 5151 along the second ramp structure 5152. The rotating member 514 and the transmission rod 512 move upward. The rack 52 contacts and meshes 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 limit component, the wedge-shaped first limit groove 561 interacts with the wedge-shaped first limit structure 571, pushing the first limit structure 571 out of the first limit groove 561. The rotating shaft I 55 does not rotate synchronously with the third gear 56, so the bevel gear I 59, bevel gear II 32 and rotating cylinder 3 do not rotate.

[0155] Example 2:

[0156] Based on Embodiment 1, this embodiment of the water-blocking device further includes an automatic control component for lifting and lowering the water-blocking plate. Referring to Figure 17, the automatic control component for lifting and lowering the water-blocking plate includes a rotary motor 34, a rotating shaft II 35, a fourth limiting member 352, a sixth elastic member 353, and a cutting mechanism 8.

[0159] The cutting mechanism 8 is located between the pressure plate 2 and the transmission assembly 5, and is used to cut off the power transmission between the pressure plate 2 and the transmission assembly 5.

[0160] Referring to Figures 1, 2, and 10-23, the cutting mechanism 8 includes a sliding plate II 81, a fifth limiting member 82, a seventh elastic member 83, and a cutting drive assembly 84;

[0161] Referring to Figures 18 and 19, the pressure plate 2 is a split structure; the pressure plate 2 includes a bottom plate 21, a top plate 22, and a support plate 23;

[0162] The upper end of the first elastic element 72 abuts against the base plate 21; the top plate 22 is slidably connected to the base plate 21, and the top plate 22 can slide up and down relative to the base plate 21. The base plate 21 is provided with a sliding groove Y211; two support plates 23 are arranged in parallel, and the lower end of each support plate 23 is provided with a sliding structure 231. The sliding structure 231 is engaged with the sliding groove Y211 on the base plate 21, and the support plate 23 can slide along the lateral direction of the base plate 21; the bottom surface of the top plate 22 is provided with a through groove along the length direction, and the side wall of the through groove is an outwardly flared slope; support structures 221 are symmetrically provided on both sides of the lateral direction of the through groove;

[0163] Two sliding plates II 81 are symmetrically arranged on both sides of the pressure 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 where the sliding plates II 81 are connected to the pressure plate 2; each connecting structure II 811 is provided with a fifth mounting groove 8111; fifth limiting members 82 are slidably arranged in the fifth mounting groove 8111, one end of the fifth limiting member 82 is provided with a fourth limiting structure 821; the other end of the fifth limiting member 82 is provided with a seventh elastic member 83; 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 of the fifth mounting groove 8111;

[0164] The sliding groove Y211 of the base plate 21 has openings on both sides in the lateral direction, and the sliding structure of the support plate 23 is provided with a plug groove 2311. The two side walls of the plug groove 2311 are provided with a fifth limiting groove 2312.

[0165] Each side of the sliding plate II 81 can extend into the side opening of the corresponding side sliding groove Y 2 1 1 and into the insertion groove 2 3 1 1 2 3 4 5 6 7 8 ...

[0166] The connection between the drive assembly 84 and the sliding plate II 81 is cut off, which is used to drive the two sliding plates II 81 to move closer or further apart from each other;

[0167] The cutting drive assembly 84 includes a threaded shaft 841, a drive shaft 842, a transmission component 843, and a motor X844; the threaded shaft 841 is threadedly connected to the sliding plate II 81 and rotatably connected to the garage ramp; the motor X844 is fixedly installed inside 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 transmitted through the transmission component 843.

[0168] Automatic lifting principle of water baffle 1:

[0169] When the water-blocking device is not needed, the operator activates the cutting mechanism 8 via the controller. The cutting mechanism 8 disconnects the power transmission between the pressure plate 2 and the sliding cylinder II 516, keeping the sliding cylinder II 516 stationary. Simultaneously, the operator activates the angle motor 34 via the controller, causing the shaft of the angle motor 34 to rotate in the forward direction (as shown by the arrow in Figure 17). This drives the fourth limiting member 352 to rotate with the rotating shaft II 35. At this time, the third limiting structure 3521 abuts against the fourth limiting groove 33. The third limiting structure 3521 drives the rotating cylinder 3 to rotate in the forward direction, causing the rotating cylinder 3 to rotate by an angle θ. This moves the drive slider 41 down to the lowest position, and the water-blocking plate 1 down to the lowest position, thereby improving the efficiency of vehicle passage.

[0170] When the water-blocking device needs to operate (managers determine whether the water-blocking device needs to operate based on weather conditions or actual rainfall), the manager stops the cutting mechanism 8 via the controller, restoring the power transmission between the pressure plate 2 and the sliding cylinder II 516. Simultaneously, the manager activates the angle motor 34 via the controller, causing its shaft to rotate forward by an angle θ, which in turn drives the rotating shaft II 35 to rotate forward. This causes 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, driving the rotating cylinder 3 to rotate forward by an angle θ, thus moving the drive slider 41 upward to its highest position to block the water. At this time, when the wheel presses the pressure plate 2 and the transmission component 5 drives the rotating cylinder 3 to rotate (as shown by the arrow in Figure 17), the side wall of the fourth limiting groove 33 generates a thrust on the third limiting structure 3521, which overcomes the elastic force of the sixth elastic element 353, causing the third limiting structure 3521 to disengage from the fourth limiting groove 33, so that the rotating cylinder 3 and the rotating shaft II 35 form a rotating connection, ensuring that the rotating cylinder 3 rotates reliably.

[0171] Furthermore, sealing element I91 and sealing element II92 are fixedly connected to the garage ramp; sealing element I91 is used to seal the gap between the side wall of the top plate 22 and the garage ramp; sealing element II92 is used to seal the gap between the side wall of the water baffle 1 and the garage ramp.

[0172] By sealing the gap between the side wall of the top plate 22 and the garage slope through the sealing component I91, the probability of water flowing down the side wall of the top plate 22 is reduced, the probability of corrosion of the support plate 23, the bottom plate 21, etc. is reduced, and the probability of water entering the garage slope along the side wall of the top plate 22 is reduced, thus reducing the probability of damage to the garage slope.

[0173] By sealing the gap between the side wall of the baffle plate 1 and the garage ramp with sealing component II92, the probability of water flowing down the side wall of the baffle plate 1 is reduced, the chance of corrosion of rotating cylinder 3, bevel gear II32, etc. is reduced, and the probability of water entering the garage ramp along the side wall of the baffle plate 1 is reduced, thus reducing the probability of damage to the garage ramp.

[0174] Cutting mechanism 8 cutting principle:

[0175] When the water-blocking device is not required to work, the manager can activate the cut-off drive assembly 84 through the controller. The cut-off drive assembly 84 drives the two sliding plates II 81 to move closer to each other, so that the sliding plates II 81 extend into the sliding groove Y211, preventing the bottom plate 21 from sliding vertically and disconnecting the power transmission between the bottom plate 21 and the sliding cylinder II 516.

[0176] When the water-blocking device needs to work, the manager activates the cut-off drive assembly 84 through the controller. The cut-off 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 groove Y211, thus restoring the bottom plate 21 to its sliding state and restoring the power transmission between the bottom plate 21 and the sliding cylinder II 516.

[0177] When the two sliding plates II81 approach each other, the connecting structure II811 of the sliding plate II81 first extends into the sliding groove Y211, and then into the insertion groove 2311 of the support plate 23, until the fourth limiting structure 821 of the fifth limiting member 82 in the connecting structure II811 abuts against the sliding structure 231 of the support plate 23 (i.e., both sides of the insertion groove 2311). The sliding plate II81 continues to move, generating a pushing force on the sliding structure 231, which drives the two support plates 23 to approach each other. When the two support plates 23 abut against each other... When they come into contact, the elastic force of the seventh elastic element 83 causes the fourth limiting structure 821 to abut against the fifth limiting groove 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 groove 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 slope can be reduced. While generating a speed bump effect, it reduces the bumps generated when the car passes by and improves 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 groove 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 groove 2312). Under the action of the inclined surface of the through groove 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 baffle 1 to move, ensuring the passage of the car while blocking the water.

[0179] Control principle of cut-off drive component 84:

[0180] When the water-blocking device is not required, the manager can activate the motor X844 through the controller, causing the motor X844 shaft to rotate in the forward direction. This, in turn, drives the threaded shaft 841 to rotate through the transmission component 843, causing the two sliding plates II 81 to move closer to each other. This causes the sliding plates II 81 to abut against the sliding groove Y211, preventing the base plate 21 from sliding vertically and thus fixing the base plate 21.

[0181] When the water-blocking device needs to work, the manager uses the controller to make the motor X844 work, so that the shaft of the motor X844 rotates in the opposite direction. Through the transmission component 843, the threaded shaft 841 rotates in the opposite direction, causing the two sliding plates II 81 to move away from each other, so that the ends of the sliding plates II 81 are disengaged from the sliding groove Y211, and the fixation on the base plate 21 is released.

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