Description

Technical Field

[0001] The invention relates to the technical field of water accumulation protection devices, and in particular to a water blocking device for parking lot entrances and exits. Background Art

[0002] With the acceleration of urbanization, underground parking lots are becoming more and more widely used. However, in extreme environments such as severe weather such as heavy rain and floods, the entrances and exits of parking lots can easily become the main channels for water accumulation, causing the underground parking lot to be soaked in water and vehicles and facilities to be damaged. Therefore, in order to protect the parking lot and its internal facilities, effective water blocking devices must be installed at the entrances and exits.

[0003] Existing parking lot water-blocking devices are mainly divided into two categories: one is manual water-blocking facilities, such as movable baffles or sandbags, and the other is automatic water-blocking facilities, such as waterproof rolling shutter doors or automatic lifting water-blocking boards.

[0024] In summary, the present invention mainly has the following beneficial effects:

[0025] 1. Dual function design to ensure comprehensive protection:

[0026] The present invention, through the combined design of the base and the water retaining plate, the boss on the base not only plays the role of a speed bump, but also cooperates with the rotation function of the water retaining plate to effectively block the influx of rainwater when there is too much rain, forming a double protection. The water retaining plate can prevent rainwater from flowing back, and can also block vehicles from entering when the accumulated water has not receded, ensuring the safety of the facilities in the parking lot.

[0028] In the present invention, when the water inflow exceeds the drainage capacity, the floating plate rises and drives the water retaining plate to rotate, automatically forming a waterproof barrier, and the locking device ensures that the water retaining plate will not be reset due to external interference before the accumulated water is drained. This design avoids the manual intervention of traditional manual water retaining facilities, improves the response speed, and plays a role quickly, especially during heavy rain.

[0029] 3. Automatic processing of foreign matter to ensure smooth drainage:

[0030] In daily use, the crushing rollers in the foreign body cavity are driven to rotate by the force of the vehicle rolling the boss, which can crush foreign objects such as leaves, mud and sand that enter with the water flow, prevent the drainage channel from being blocked, and ensure that the sewage can be discharged smoothly. This design greatly improves the reliability of the drainage system and is particularly suitable for handling large amounts of water during heavy rain.

[0031] 4. Intelligent management, automatic reset, easy operation:

[0032] In the present invention, the water retaining plate can be automatically reset after the water level drops through the design of the base, without the need for manual intervention. When the accumulated water is removed, when the vehicle is about to drive into the parking lot, the water retaining plate returns to its initial state, and the parking lot entrance and exit are reopened to ensure smooth passage of vehicles and pedestrians. This automatic reset function greatly improves the operational convenience and safety of the system.

[0033] 5. Adapt to extreme weather, the system is robust and reliable:

[0034] The present invention can continue to work effectively under extreme weather conditions, whether it is heavy rain or long-term water accumulation. The locking mechanism of the water retaining plate ensures its stability under high water pressure, avoiding the deformation or failure problem that the automatic water retaining facility may occur when dealing with high water pressure.

[0035] The above beneficial effects enable the present invention to have the advantages of high efficiency, intelligence and safety in the process of treating water accumulation in parking lots, and solve many shortcomings of traditional water blocking devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] refer to Figure 1-Figure 13 , a water blocking device for a parking lot entrance and exit, comprising:

[0058] A base 100, wherein a foreign body cavity 101 and a sewage cavity 102 are formed in the base 100, and a liquid outlet 103 is formed in the sewage cavity 102;

[0059] A liquid inlet 104 is provided on the base 100 and communicates with the foreign body cavity 101;

[0060] The floating plate 105 is arranged in the sewage chamber 102 and is located above the liquid outlet 103;

[0061] A water baffle 106 is disposed on the base 100, and the water baffle 106 is rotatably disposed on the base 100;

[0062] A boss 107 is provided on the base 100, and a plurality of crushing rollers 108 are provided in the foreign body chamber 101;

[0063] The water retaining member provided between the floating plate 105 and the water retaining plate 106 is used to rotate the position of the water retaining plate 106 when the floating plate 105 moves upward, and the water retaining plate 106 can be locked every time it rotates a predetermined angle;

[0064] The crushing component provided between the boss 107 and the crushing roller 108 is used to rotate the crushing roller 108 when the boss 107 moves downward. The crushing roller 108 rotates in only one direction. When the boss 107 moves downward, the angle of the water retaining plate 106 can also be unlocked;

[0065] When the boss 107 moves downward to a preset position, the foreign matter in the liquid inlet 104 can be transported into the foreign matter cavity 101;

[0066] By setting the base 100, when in use, the base 100 can be pre-buried at the entrance and exit of the parking lot, and the liquid outlet 103 is connected to the drainage channel. The multiple bosses 107 set on the base 100 can also act as speed bumps. When the parking lot encounters rain or water accumulation, rainwater first enters the base 100 through the liquid inlet 104. When the water intake is less than or equal to the drainage volume of the liquid outlet 103, the float 105 will not rise due to the increase in liquid. When the water intake is greater than the drainage volume of the liquid outlet 103, the rainwater in the liquid inlet 104 and the foreign body cavity 101 will push the float 105 to move upward. The rise of the float 105 drives the action of the water retaining component, causing the water retaining plate 106 to start rotating. When the float 105 rises to a certain height, the water baffle 106 rotates to a predetermined angle and is locked in this position, forming a waterproof barrier, effectively preventing more water from continuing to flow into the underground parking lot. The angle of the water baffle 106 is locked so that it is not affected by the surge of rainwater or external interference, preventing it from accidentally resetting due to vibration or fluctuation, and effectively preventing more rainwater from entering the parking lot. In addition, since the liquid inlet 104 is connected to the foreign body chamber 101, during daily use, foreign matter in the rainwater (such as leaves, mud, etc.) will flow into the foreign body chamber 101 with the water. In order to prevent foreign matter from clogging the drainage channel, a plurality of crushing rollers 108 are arranged in the foreign matter chamber 101. When a vehicle entering or leaving the parking lot runs over the boss 107, the boss 107 is forced to move downward, so as to drive the crushing rollers 108 to rotate through the crushing components. The crushing rollers 108 can crush larger foreign matter entering the chamber, ensuring that sewage can pass through the drainage system smoothly, so as to ensure that during heavy rains, the external accumulated water can smoothly pass through the liquid inlet and foreign matter chamber 101 into the sewage chamber 102. The entire system can maintain normal operation in extreme weather conditions by crushing foreign matter and adjusting the drainage volume, thus avoiding parking accidents. The facilities and vehicles in the parking lot are damaged by rainwater. Furthermore, during the period of water accumulation, even if a vehicle accidentally drives on the base 100, the water in the sewage chamber 102 has not been completely drained, that is, the angle of the current water retaining plate 106 is still in the rotated state. The water retaining plate 106 can protrude from the base 100 after rotation, and can also block cars from entering the parking lot, preventing vehicles from rashly driving in when the water level has not completely receded, causing damage to the vehicle or secondary damage to the facilities in the parking lot. The protruding design of the water retaining plate 106 can not only prevent rainwater from backflowing, but also has a certain physical blocking function, forming a double protection mechanism. On the one hand, it can block the water flow and prevent more rainwater from pouring in. On the other hand, it acts as a physical barrier to prevent vehicles or other objects from entering areas where the situation is not yet clear in extreme rainstorm weather.This design takes into account the emergencies under the conditions of heavy rain or water accumulation, making the parking lot management more intelligent and safer. When the rain stops and the water level begins to drop, the accumulated water can be discharged from the liquid outlet 103, while the angle of the water retaining plate 106 is still locked at this time. This locking mechanism ensures that the water retaining plate 106 will not be reset in advance due to slight fluctuations in the water level or external interference, thereby preventing any undischarged accumulated water from pouring into the parking lot. At this time, the water retaining system continues to effectively block the entry of residual water flow or foreign matter. After the accumulated water completely subsides, when the vehicle is about to enter the parking lot while driving on the base 100, the downward displacement of the boss 107 can unlock the angle lock of the water retaining plate 106. At this time, after the accumulated water in the sewage chamber 102 subsides, the floating plate 105 can completely fall back to the lowest point, and the water retaining plate 106 automatically resets to the initial state, and the entrance and exit of the parking lot are restored to the normal traffic state, ensuring that vehicles and pedestrians can enter and exit safely and smoothly. The entire system realizes automatic reset from water accumulation protection to drainage completion without human intervention, which greatly improves the convenience and safety of operation. In response to the technical problems of existing parking lot water-blocking devices, this device solves the problems of slow response speed and untimely deployment of traditional manual water-blocking facilities through innovative design, while avoiding the risk of failure of automatic water-blocking facilities when dealing with high water pressure or long-term water accumulation.

[0067] As a further solution of the present invention, the water retaining member includes a first traction rope 200 connected to the bottom of the floating plate 105, a traction shaft 201 is connected to the water retaining plate 106, one end of the first traction rope 200 is wound around the traction shaft 201, a first spring 202 is connected between the floating plate 105 and the sewage chamber 102, a groove 203 is opened on the base 100, and the water retaining plate 106 is rotatably connected in the groove 203;

[0068] By setting the first traction rope 200, when the water inflow increases, the liquid level in the sewage chamber 102 rises, and the floating plate 105 gradually moves upward under the buoyancy of the water. As the floating plate 105 rises, the first traction rope 200 connected to the bottom of the floating plate 105 is tightened, and the first traction rope 200 is wound on the traction shaft 201, thereby driving the traction shaft 201 to rotate. The rotation of the traction shaft 201 is transmitted to the water retaining plate 106 through the mechanical structure, causing the water retaining plate 106 to start rotating around its axis point. When the float 105 rises to a certain height, the traction shaft 201 drives the water baffle 106 to rotate to a predetermined angle, forming an effective waterproof barrier to prevent external rainwater from continuing to flow into the parking lot. In addition, the water baffle 106 is arranged in the groove 203. When the first traction rope 200 is provided to tow the water baffle 106 to rotate, the water baffle 106 can still be in the groove 203 even after rotation. The cooperation between the water baffle 106 and the groove 203 can prevent the accumulated water from flowing out of the first traction rope 200 and the groove 203 of the water baffle 106.

[0069] As a further solution of the present invention, a locking strip 204 is slidably connected in the groove 203, and locking blocks 205 are respectively connected to the inner sides of the locking strip 204, and the bottom of the water baffle 106 is rotatably connected to a connecting rod 206, and the bottom of the connecting rod 206 is rotatably connected to a connecting shaft 207, and the two ends of the connecting shaft 207 are respectively slidably connected to locking convex strips 208, and a second spring 209 is connected between the locking convex strip 208 and the connecting shaft 207, and a spring telescopic rod 210 is connected in the groove 203, and the connecting shaft 207 is rotatably connected to the telescopic shaft of the spring telescopic rod 210;

[0070] By setting the spring telescopic rod 210, the spring telescopic rod 210 can limit the position of the connecting shaft 207 to ensure the position of the connecting rod 206. When the water baffle 106 rotates, one end of the connecting rod 206 and the connecting shaft 207 can move along the path of the locking strip 204 and compress the spring telescopic rod 210 to generate potential energy. When the connecting shaft 207 moves, the provided locking block 205 can press the locking convex strip 208 and compress the second spring 209 to generate potential energy. After the locking convex strip 208 leaves a locking block 205, the locking boss 107 can be reset to limit the current position of the connecting shaft 207. The first spring 202 is in the position to ensure that the water baffle 106 will not reset. When the float 105 moves upward to the limit position or the sewage is not enough to overcome the force of the first spring 202 to allow the float 105 to continue to rise, or when sludge accumulates on the float 105 and the buoyancy of the float 105 is not enough to overcome the pressure of the sludge and continue to rise, when the accumulated water ripples and impacts the water baffle 106, the water baffle 106 can also rotate clockwise to ensure that the water baffle 106 can rotate to the limit angle. Through this design, the water baffle 106 can not only automatically adjust to the appropriate angle during normal operation, but also maintain its function and prevent water from flowing back into the parking lot when encountering sudden water flow impact.

[0071] As a further solution of the present invention, the crushing component includes a connecting plate 300 connected to the foreign body chamber 101, the crushing roller 108 is rotatably connected to the connecting plate 300 and protrudes from the connecting plate 300, the crushing roller 108 is connected to a gear 301, the boss 107 is connected to a rack 302 meshing with the gear 301, and a first chain transmission mechanism 303 is connected between every two crushing rollers 108;

[0072] By providing a rack 302, the rack 302 meshes with the gear 301 on the crushing roller 108, so that the crushing roller 108 can be rotated. When the vehicle passes through the boss 107 of the base 100, the rack 302 on the boss 107 will mesh with the gear 301 on the crushing roller 108, thereby driving the crushing roller 108 to rotate. This meshing mechanism of the rack 302 and the gear 301 can convert the driving pressure of the vehicle into the rotation force of the crushing roller 108, ensuring that the crushing roller 108 can operate effectively. The crushing roller 108 can crush larger foreign objects in the foreign object chamber 101, such as leaves, mud and sand, etc., during the rotation process. These foreign bodies are crushed by the crushing rollers 108 when entering the foreign body chamber 101, and the crushed foreign bodies can be discharged smoothly. The first chain transmission mechanism 303 connects the movements between the crushing rollers 108 to ensure that all crushing rollers 108 can operate synchronously, thereby improving the crushing efficiency and the overall stability of the system. Through this design, the system can effectively handle various large foreign bodies flowing into the foreign body chamber 101 and keep the drainage channel unobstructed. The efficient operation of the entire mechanism not only enhances the drainage capacity of the parking lot, but also improves the reliability and durability of the waterproof system.

[0073] As a further solution of the present invention, a connection port 304 is provided on the base 100, the boss 107 is slidably connected in the connection port 304, and a third spring 305 is connected between the boss 107 and the connection port 304;

[0074] By setting the third spring 305, the sliding connection between the boss 107 and the connection port 304 can be effectively supported and buffered. The function of the third spring 305 is to maintain the stable position of the boss 107 in the connection port 304 and absorb the impact caused by the vehicle rolling or other external forces. The third spring 305 can automatically adjust the position of the boss 107 according to the change of the external force, ensuring that the boss 107 always remains within the predetermined working range. When the vehicle passes the boss 107 on the base 100, the third spring 305 will compress according to the weight and movement of the vehicle, so that the boss 107 slides smoothly in the connection port 304, while alleviating the instantaneous impact force caused by the vehicle rolling on the system. The elasticity of the spring can also help the boss 107 to return to the original position quickly, and the elastic force of the third spring 305 can help the boss 107 to return quickly after the operation is completed. Especially after handling the foreign matter, the third spring 305 can pull the boss 107 back to the original position to ensure the normal operation of the system and prepare for the next operation cycle.

[0075] As a further solution of the present invention, a ratchet mechanism 306 is connected between the gear 301 and the crushing roller 108;

[0076] By providing the ratchet mechanism 306, the transmission between the gear 301 and the crushing roller 108 can realize unidirectional movement, thereby ensuring that the rotation direction of the crushing roller 108 remains consistent. The ratchet mechanism 306 can allow the gear 301 to rotate freely in one direction, while being locked in the opposite direction, thereby preventing the crushing roller 108 from moving in the reverse direction in which rotation is not required, thereby preventing foreign matter from wandering in the foreign matter chamber 101, thereby ensuring the stability and efficiency of the crushing function.

[0077] As a further solution of the present invention, a plurality of conveying shafts 400 are rotatably connected in the liquid inlet 104, a rotating shaft 401 is connected to the lowest conveying shaft 400, a connecting rod 402 is connected to the bottom of the boss 107, a connecting channel 403 is opened between the liquid inlet 104 and the connecting port 304, a second traction rope 404 is wound on the rotating shaft 401, the second traction rope 404 extends into the connecting channel 403 and is connected to the connecting rod 402, a second chain transmission mechanism 405 is connected between every two adjacent conveying shafts 400, and a connecting rod is connected between the locking bar 204 and an adjacent connecting rod 402;

[0078] By setting up a second traction rope 404, when a vehicle rolls over the boss 107, the boss 107 will be displaced downward, and the connecting rod 402 converts this displacement into a pulling action on the conveying shaft 400 through the second traction rope 404, driving the conveying shaft 400 to rotate, and every two adjacent conveying shafts 400 are connected by a second chain transmission mechanism 405, so that multiple conveying shafts 400 can achieve synchronous rotation driven by the second traction rope 404. This design ensures that the power distribution inside the system is uniform. When the conveying shaft 400 rotates, the foreign matter in the liquid inlet 104 can be transported to the foreign matter chamber 101 by the rotation of the conveying shaft 400. This design ensures that when a vehicle passes through the system, the foreign matter can be effectively transferred from the liquid inlet 104 to the foreign matter chamber 101 and processed, thereby ensuring the smooth flow of the drainage system and avoiding the problem of poor drainage caused by foreign matter blockage. In addition, the connecting bar is set, and when the water recedes and the vehicle travels on the base 100, the boss 107 is forced to move downward, which can pass The rack 302 and the gear 301 allow the multiple crushing rollers 108 to rotate, and the rotation of the crushing rollers 108 can allow the multiple crushing rollers to rotate synchronously through the first chain transmission mechanism 303. At this time, the multiple bosses 107 move downward synchronously, and one of the connecting rods 402 is connected to the locking bar 204 through a connecting rod, which can ensure that when the vehicle travels on the base 100, the locking bar 204 can move downward to allow the locking block 205 to leave the locking convex strip 208. At this time, the spring telescopic rod 210 can reset the position of the connecting rod 206 to allow the water retaining plate 106 to reset and rotate without affecting the passage of the vehicle.

[0079] As a further solution of the present invention, a side opening 500 is provided in the liquid inlet 104, a push plate 501 is slidably connected in the side opening 500, a connecting tube 502 slidably connected to the connecting channel 403 is connected to one side of the push plate 501, a third traction rope 503 is connected to the connecting rod 402, the third traction rope 503 is connected to the connecting tube 502, the second traction rope 404 is connected to the connecting tube 502, and a fourth spring 504 is connected between the push plate 501 and the side opening 500;

[0080] By setting the third traction rope 503, when the connecting rod 402 moves downward following the boss 107, the third traction rope 503 can be pulled, and the push plate 501 can be moved through the connecting tube 502. At the same time, the second traction rope 404 can pull the conveying shaft 400 to rotate. After moving, the push plate 501 can push the foreign matter in the liquid inlet 104 to increase the friction between the foreign matter and the conveying shaft 400, so as to ensure that when the conveying shaft 400 rotates, the foreign matter can be effectively transmitted to the foreign matter cavity 101.

[0081] As a further solution of the present invention, a connecting ring 505 is connected inside the liquid inlet 104, and a fifth spring 506 is connected between the connecting ring 505 and the rotating shaft 401;

[0082] By providing the fifth spring 506 , when the boss 107 performs the reset motion, the fifth spring 506 releases potential energy, so that the rotating shaft 401 can reset and rotate, and wind the second traction rope 404 again, so as to prepare for the next rotation of the conveying shaft 400 .

[0083] As a further solution of the present invention, a ratchet mechanism 306 is also provided between the rotating shaft 401 and the conveying shaft 400;

[0084] By setting up the ratchet mechanism 306, when the second traction rope 404 pulls the rotating shaft 401, the rotating shaft 401 can rotate the conveying shaft 400 through the ratchet mechanism 306. When the rotating shaft 401 is reset and rotated around the second traction rope 404 by the force of the fifth spring 506, the rotating shaft 401 can idle outside the conveying shaft 400, avoiding the conveying shaft 400 from rotating in the opposite direction, allowing foreign matter to wander in the liquid inlet 104 and making it difficult to enter the foreign matter cavity 101.

[0085] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
