Description

Technical Field

[0001] This invention relates to the field of urban flood control technology, and in particular to an underground multi-level parking garage for flood prevention that can be used in both normal and emergency situations, and its control method. Background Technology

[0002] With the continued advancement of urbanization, the scarcity of land resources and the frequent occurrence of extreme weather events have become prominent contradictions restricting the sustainable development of cities. In the field of parking and disaster prevention, this contradiction manifests as a dual dilemma: on the one hand, traditional surface parking lots have a high land occupation ratio and are difficult to adapt to the parking needs of high-density urban areas. Although conventional multi-level parking garages improve utilization through space stacking, their functions are limited and they cannot cope with disaster scenarios such as urban flooding. On the other hand, existing underground parking garages generally have weak flood protection capabilities. During heavy rainfall, vehicles are easily flooded due to rainwater backflow, which has caused significant economic losses in recent years.

[0003] However, existing multi-level parking garage designs are mostly simple combinations of water storage tanks and parking garages, failing to effectively connect parking functions with rainwater storage functions, and the overall utilization efficiency of underground space is still insufficient.

[0004] Therefore, there is an urgent need to develop a comprehensive system that integrates multi-level parking, flood prevention, and rainwater resource utilization, so that it can not only meet daily parking needs, but also actively convert into a water storage facility during the flood season, while realizing rainwater purification and reuse, thereby improving urban resilience and the level of resource recycling. Summary of the Invention

[0005] To address the aforementioned shortcomings, this invention provides a dual-purpose underground parking garage for flood control and its control method, which solves the problems of insufficient parking space and flood storage space, poor functional integration of existing devices, and low utilization efficiency of underground space. It enables intelligent conversion between parking space and storage space, meets daily parking needs, and actively converts into water storage facilities during the flood season. At the same time, it achieves rainwater purification and reuse, thereby improving the city's flood control capabilities and resource recycling level.

[0006] In order to achieve the objectives of this invention, the following technologies are proposed: A dual-purpose underground multi-level parking garage for emergency and normal use, designed to prevent flooding, includes: The parking garage is partially or entirely located underground. The parking garage contains multiple parking levels arranged vertically. The parking levels include multiple regular parking levels at the bottom and multiple high-rise parking levels at the top. Each regular parking level has multiple parking spaces, each with a parking platform. Each regular parking level also has several horizontal guide rails. A water level sensor is installed on the inner wall of the uppermost regular parking level. The high-rise parking levels have multiple emergency parking spaces and several vehicle storage and retrieval spaces. Vehicle information reading devices are installed in the vehicle storage and retrieval spaces. Several vehicle transport units are located inside the parking box. Each vehicle transport unit includes four vertically arranged guide rails that pass through each parking level. A vehicle carrier is vertically slidably connected between the guide rails. Multiple sets of vehicle carriers, each set including multiple vehicle carriers installed in each parking level during use. All vehicle carriers have independent identification information. The vehicle carriers are used to transport vehicles into or out of the parking platform in a direction perpendicular to the transverse guide rail, and to engage or disengage from the vehicle carrier. The lower end of the vehicle carrier is equipped with a walking mechanism. The processing unit is preset with threshold and safety values, and is connected to the water level sensor, vehicle information reading device, and vehicle platform.

[0007] Furthermore, an electric safety door for storing and retrieving vehicles is installed at one end of the vehicle storage space.

[0008] Furthermore, each vehicle storage and retrieval space is equipped with a storage slot located on one side of any of the upper parking levels, where the vehicle platform is stored when not in use.

[0009] Furthermore, the vehicle carrier has vertical holes at its four corners that are fitted onto the vertical guide rails. The vehicle carrier unit also includes four drive mechanisms located on one side of each vertical guide rail. Each drive mechanism includes a drive gear, a driven gear located below the drive gear, and a chain connecting the drive gear and the driven gear. The vehicle carrier is rigidly connected between the four chains and is in a horizontal state during operation.

[0010] Furthermore, the parking platform is equipped with a vehicle platform moving groove and a vehicle platform fixing slot for fixing the vehicle platform.

[0011] Furthermore, it also includes a rainwater transition chamber located at one end of the parking compartment. This chamber has a rectangular cavity structure, and a water level sensor is installed on the inner wall of the rainwater transition chamber. An external rainwater pipe is connected to the upper part of one side of the rainwater transition chamber, and an automatic water inlet gate is installed at the water inlet end. An emergency control gate is installed at the connection end between the external rainwater pipe and the rainwater transition chamber. A walkway is provided on the upper surface of the outer side of the rainwater transition chamber. Several rainwater grates are provided on the ground on one side of the walkway. The drain end of the rainwater grates is connected to the automatic water inlet gate. An initial rainwater pollution control pool is connected to the lower end of the rainwater transition chamber, and a sludge collection hopper is installed at the bottom of the pool. A submersible sewage pump is also installed in the pool, and the pump is connected to the urban drainage system through a sewage pressure pipe. A rainwater overflow weir extending to the parking compartment is provided on the other side of the rainwater transition chamber, and an overflow filter is installed inside the weir. A rainwater inlet and outlet, both equipped with valves, are provided on one end of the rainwater pollution control pool.

[0012] Furthermore, it also includes a rainwater purification and reuse unit, which includes a rainwater purification device located at the bottom of the high-rise parking level and a lift pump located at the bottom of the regular parking level. The lift pump lifts rainwater to the rainwater purification device through a lift pipe, and a rainwater pressure pipe connected to the municipal rainwater pipe is installed around the lift pipe.

[0013] A control method for a dual-purpose underground parking garage for flood prevention and control, comprising the following steps: S100: When parking begins, the processing unit assigns a vehicle carrier to the vehicle to be parked and obtains the vehicle carrier's identity information. S200: Within the vehicle storage and retrieval space, the vehicle carrier plate engages with the vehicle carrier of the vehicle transport unit. S300: After the vehicle to be stored arrives at the vehicle platform, the vehicle information reading device reads the vehicle information to obtain the vehicle information. S400: The processing unit associates the vehicle information with the identity information of the assigned vehicle platform, assigns a parking location information to the current vehicle platform, and then controls the vehicle carrier of the vehicle transport unit to transport the vehicle platform carrying the corresponding vehicle to the corresponding normal parking level along the vertical guide rail. S500: The vehicle carrier is separated from the vehicle carrier. The vehicle carrier moves along the transverse guide rail and then transports the vehicle into the parking platform at the corresponding parking position. S600: When the processing unit determines that the water level in the parking tank is higher than the threshold, the following operations are performed on the vehicles in the normal parking layer from the bottom up: the vehicles are transported out of the parking platform by the vehicle carrier, and then the vehicle carrier and its transport vehicle are moved along the transverse guide rail. Then the vehicle carrier carrying the corresponding vehicle is transported along the vertical guide rail to the high-level parking layer with available emergency parking spaces by the vehicle carrier. The vehicle is then transported to the emergency parking space by the vehicle carrier. S700: When the processing unit determines that the water level in the parking tank is lower than the safe value, it executes S200~S500 sequentially for the vehicles in the emergency parking space until all vehicles return to the parking platform.

[0014] Furthermore, vehicle retrieval is permitted during periods when no operations are being performed in the parking garage. The retrieval process includes: The processing unit receives a request from the vehicle owner, which includes at least the license plate information, and then obtains the associated vehicle board's identity information and current parking location information based on the license plate information. The vehicle carrier lifts the vehicle off the parking platform and positions it on the transverse guide rails. The vehicle carrier is controlled to move along the vertical guide rail to the parking level where the vehicle is located and to engage with the corresponding vehicle platform. The vehicle carrier transports the corresponding vehicle platform to the vehicle storage and retrieval space along the vertical guide rails. After the vehicle leaves the storage and retrieval space, the corresponding vehicle carrier plate will be separated from the vehicle carrier.

[0015] The beneficial effects of this technical solution are as follows: 1. By setting up multi-level parking garages combined with vehicle transport units that can move along vertical guide rails and vehicle platforms with walking mechanisms, the efficient use of multi-level parking space is achieved, effectively alleviating the problems of high land occupation rate of traditional ground parking lots and insufficient capacity of conventional multi-level parking garages.

[0016] 2. This invention does not adopt a simple combination of a water storage tank and a parking garage. Instead, it achieves intelligent vehicle storage and retrieval management by linking vehicle information and vehicle platform identity information through a processing unit. It also uses a water level sensor to monitor the emergency water level in real time. When the water level reaches a threshold, it can automatically control the vehicle transport unit to quickly move vehicles from the lowest parking level to the higher parking level, dynamically freeing up the bottom space to form an effective volume for storing rainwater. This realizes an active and intelligent connection between daily parking functions and rainwater storage functions during the flood season, greatly improving the comprehensive utilization efficiency of underground space and the city's vehicle protection and rainwater storage capacity in response to urban flooding.

[0026] The present application will be further described below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1-7 The underground multi-level parking garage shown is designed for both emergency and normal use to prevent urban flooding. It includes a parking box 1, a vehicle transport unit, a vehicle platform 27, a rainwater transition chamber 8, a rainwater purification and reuse unit, and a treatment unit.

[0028] The parking garage 1 is partially or entirely underground. It contains multiple vertically arranged parking levels, including several regular parking levels at the bottom and several upper parking levels above them. Each regular parking level has multiple parking spaces arranged along two parallel straight lines, each with a parking platform 2. Each regular parking level also has several transverse guide rails 4, specifically two rails per level, providing path support for the lateral movement of the vehicle platform 27. A water level sensor 5 is installed on the inner wall of the uppermost regular parking level to monitor emergency water level information related to the parking garage 1. The upper parking levels have multiple emergency parking spaces 7 and several vehicle retrieval spaces 21. Each emergency parking space 7 has independent coded information. When the processing unit determines that the water level has reached a threshold and moves the vehicle to an emergency parking space 7, it will... The encoded information is assigned to the vehicle carrier 27 that moves the vehicle. One end of the storage space 21 is equipped with a storage electric safety door 20. After the storage electric safety door 20 is opened, the vehicle can drive into the storage space 21 from the outside and drive out of the storage space 21. The storage space 21 is equipped with a vehicle information reading device 19, which is used to obtain the vehicle information of the vehicle to be stored by taking pictures or recording videos when the vehicle storage begins. The vehicle information includes at least the license plate information and the owner's communication information. Specifically, the vehicle information reading device 19 reads the license plate information. In this embodiment, the vehicle information reading device 19 adopts a high-definition camera. The vehicle information reading device 19 can also be set as an information receiving unit, which can receive the license plate information entered by the user after scanning the QR code. Each storage space 21 has a storage slot 22 located in any high-rise parking level on one side.

[0029] The vehicle transport units are arranged in several units within the parking compartment 1. Each vehicle transport unit includes four vertically arranged guide rails 3 that pass through each parking level, focusing on realizing vertical transportation across parking levels. The vertical guide rails 3 can reach each parking level. Each vertical guide rail 3 is located at one of the four corners of a rectangle on the horizontal plane. A vehicle carrier 33 is vertically slidably connected between each vertical guide rail 3. Specifically, the four corners of the vehicle carrier 33 are provided with vertical holes that fit into the vertical guide rails 3. The vehicle transport unit also includes four drive mechanisms located on one side of each vertical guide rail 3. The drive mechanism includes a drive gear 30, a driven gear 31 located below the drive gear 30, and a chain 32 connecting the drive gear 30 and the driven gear 31. The vehicle carrier 33 is rigidly connected between the four chains 32 and is in a horizontal state during operation, forming a linkage transmission system of "gear-chain-vehicle carrier".

[0030] The drive gear 30 is directly connected to the motor output shaft. When the motor is running stably, it drives the drive gear 30 to rotate, which in turn drives the driven gear 31 to rotate synchronously through the meshing transmission of the chain 32. Four drive gears 30 are located in the top area of ​​the parking garage 1, and four driven gears 31 are arranged vertically corresponding to the positions of the four drive gears 30 in the lowest parking level area of ​​the parking garage 1. This vertical alignment allows the chain 32 to vertically penetrate all parking levels of the parking garage 1, forming a transmission path covering the entire floor. Furthermore, the vehicle carrier 33 slides with the vertical guide rail 3, providing precise guidance for the vertical movement of the vehicle carrier 33, preventing vehicle swaying, and ensuring stability and safety during movement. When the motor drives the drive gear 30 to rotate, the chain 32 will circulate along the drive gear 30 and the driven gear 31, thereby driving the vehicle carrier 33 fixed to the chain 32 to move stably along the vertical guide rail 3, realizing the vertical cross-level transportation of the vehicle carrier 33 between various parking levels, providing reliable power transmission guarantee for efficient vehicle storage and retrieval and rapid vehicle relocation in emergency situations.

[0031] The number of vehicle carriers 27 is in multiple sets, each set including multiple vehicle carriers 27 installed in each parking level during use. Each vehicle carrier 27 has independent identification information. When parking a vehicle, each vehicle to be parked is assigned a vehicle carrier 27. The processing unit associates the vehicle information of the currently parked vehicle with the identification information of the assigned vehicle carrier 27 and assigns a parking position information to the current vehicle carrier 27. The vehicle carrier 27 is used to transport vehicles into or out of the parking platform 2 in a direction perpendicular to the transverse guide rail 4, and to engage or disengage from the vehicle carrier 33. The vehicle carrier 27 in non-use state is stored in the storage slot 22. The lower end of the vehicle carrier 27 is provided with a walking mechanism. Specifically, the walking mechanism includes multiple drive motors, and each drive motor output end is equipped with a roller. The parking platform 2 is a stainless steel structure, and is provided with a vehicle carrier moving slot and a vehicle carrier fixing slot for fixing the vehicle carrier 27.

[0032] Regarding the storage and retrieval of the vehicle carrier 27, corresponding to the vehicle storage and retrieval space 21, multiple vehicle carriers 27 are placed in the storage slot 22 in a vertically stacked manner. The vehicle carrier plate 27 can be configured for top-down storage and retrieval. A pusher device can be installed corresponding to the storage slot 22. When the vehicle carrier plate 27 needs to be engaged with the vehicle carrier 33, the vehicle carrier can be moved to a position that matches the current stacking height of the vehicle carrier plate 27 in the storage slot 22. Then, the pusher device pushes the vehicle carrier plate 27 to the engagement position with the vehicle carrier 33. The engagement of the vehicle carrier plate 27 with the vehicle carrier 33 is then achieved through the quick-connect mechanical structure and electronic or magnetic control, as described above. When the vehicle is removed, the vehicle carrier 33, still with the vehicle carrier plate 27 engaged, can be moved to a position slightly higher than the current stacking height of the vehicle carrier plate 27 in the storage slot 22. Then, the quick-connect mechanical structure is released via magnetic or electronic control, thereby detaching the vehicle carrier plate 27 from the vehicle carrier 33. At this point, the pusher device on the other side can push the vehicle carrier plate 27 into the storage slot 22, thus storing the vehicle carrier plate 27.

[0033] The vehicle platform 27 is also equipped with a route planning unit. The route planning unit is used to plan a path based on the current location information of the vehicle platform 27 and the code information of the emergency parking space it is assigned after the vehicle platform 27 is transported to the high parking level. It can also control the walking mechanism to walk along the planned path so that the vehicle platform 27 can enter the corresponding emergency parking space 7.

[0034] By setting up an emergency parking area 6 and coded emergency parking spaces 7 on the top outer platform of the parking box 1, and combining the route planning unit and walking mechanism of the vehicle carrier 27, the vehicle carrier 27 can autonomously and accurately enter the designated emergency parking space 7 in an emergency, thereby improving the efficiency and safety of vehicle transfer and parking during the flood season.

[0035] By setting up multi-level parking garages 1, combined with vehicle transport units that can move along vertical guide rails 3 and vehicle carriers 27 with walking mechanisms, the efficient utilization of three-dimensional parking space is achieved. Specifically, the vehicle transporter 33 is responsible for cross-level transport along the vertical guide rails 3, and the vehicle carrier 27, after detaching from the transporter, moves independently to the parking position along the horizontal guide rails 4 via the walking mechanism. This significantly increases the parking capacity per unit area and effectively alleviates the problem of high land occupation and difficulty in adapting to the parking needs of high-density urban areas in traditional ground parking lots. At the same time, the design of allowing the vehicle carrier 27 to be joined and detached from the vehicle transporter 33 enables the vehicle carrier 27 to be reused, ensuring the stability of vehicle transfer and improving equipment utilization efficiency.

[0036] After the vehicle information reading device accurately acquires vehicle information, the processing unit associates the vehicle information with the independent identity information of the vehicle carrier 27 and allocates parking positions to achieve intelligent management of vehicle storage, improving the efficiency and accuracy of vehicle storage and retrieval. Crucially, the water level sensor 5 monitors the emergency water level in real time. When the threshold is reached, the processing unit can quickly control the vehicle transport unit to move the vehicle carrier 27 (including the vehicle) from the lowest parking level to a higher parking level, dynamically freeing up the bottom space to form a water storage volume. This breaks away from the existing simple "water storage tank superimposed on parking garage" model, achieving proactive and intelligent integration of daily parking and rainwater storage during the flood season, significantly improving the comprehensive utilization efficiency of underground space and the city's flood prevention capabilities.

[0037] A rainwater transition chamber 8 is located at one end of the parking compartment 1. The rainwater transition chamber 8 has a rectangular cavity structure, and the upper and lower ends of the cuboid are respectively at the same horizontal level as the upper and lower ends of the normal parking level. To achieve precise control of rainwater storage, a water level sensor 5 is also installed on the inner wall of the rainwater transition chamber 8. An external rainwater pipe 9 is connected to the upper part of one side of the rainwater transition chamber 8, and an automatic water inlet gate 10 is provided at its inlet end. An emergency control gate 11 is provided at the connection end between the external rainwater pipe 9 and the rainwater transition chamber 8. The automatic water inlet gate 10... The coordinated opening and closing of the emergency control gate 11 allows for flexible adjustment of rainwater inflow based on water level changes and emergency needs, ensuring the controllability of the rainwater storage process. A walkway 28 is provided on the upper outer surface of the rainwater transition chamber 8, enabling multi-functional use of space. Several rainwater grates 29 are installed on one side of the walkway 28 to systematically introduce external rainwater into the rainwater transition chamber 8, providing initial storage space for rainwater storage during the flood season. The drain ends of the rainwater grates 29 are connected to the automatic inlet gate 10, and the lower end of the rainwater transition chamber 8 is connected to an initial rainwater drainage system. The initial rainwater pollution control tank 23 has a sludge collection hopper 12 installed at its bottom. The sludge collection hopper 12 has a slope of not less than 20%, and the bottom slope of the initial rainwater pollution control tank 23 is not less than 5%. This stepped slope design efficiently guides the silt and impurities carried by rainwater to collect and settle in the sludge collection hopper 12, effectively reducing rainwater pollution. The rainwater pollution control tank 23 also contains a submersible sewage pump 24, which is connected to the urban drainage system via a sewage pressure pipe 25, facilitating the centralized cleaning and discharge of deposited impurities. On the other side of the transition chamber 8, a rainwater overflow weir 13 is provided, extending to the parking space 1, forming a controllable channel for rainwater to flow from the transition chamber to the parking space. To further improve the rainwater purification effect, an overflow filter 14 is built into the rainwater overflow weir 13, which can perform secondary filtration on the rainwater overflowing from the rainwater transition chamber 8, effectively intercepting unsettled impurities, reducing pollution to the parking space of the parking space 1, and ensuring the cleanliness of the water storage area. One end of the rainwater pollution control pool 23 is provided with a rainwater inlet 81 and a rainwater outlet 82, both equipped with valves. Among them, the rainwater in the rainwater transition chamber 8, after sedimentation treatment, can enter the initial rainwater pollution control pool 23 through the rainwater inlet 81 for deep purification treatment. After purification to meet the standards, it is discharged through the rainwater outlet 82, providing a guarantee for subsequent rainwater resource reuse or safe discharge.

[0038] The rainwater purification and reuse unit includes a rainwater purification device 16 located at the bottom of the high-rise parking level and a lift pump 15 located at the bottom of the regular parking level. The lift pump 15 lifts rainwater to the rainwater purification device 16 through a lift pipe 17. A rainwater pressure pipe 18 connected to the municipal rainwater pipe is installed around the lift pipe 17. Specifically, a pipe pressure detector located below the rainwater pressure pipe 18 is also installed around the lift pipe 17. A solenoid valve is provided at the inlet end of the rainwater pressure pipe 18. When the pipe pressure detector detects a water pressure higher than a predetermined pressure, the solenoid valve opens and discharges some rainwater.

[0039] The rainwater purification device 16 is equipped with a filtration and disinfection treatment device. After filtration and disinfection, the rainwater can be treated to meet the standards for municipal miscellaneous water use. In this embodiment, a rainwater utilization device 26 can also be set up and connected to the rainwater purification device 16. Specifically, the rainwater utilization device 26 is an automatic car wash device or an automatic sprinkler device, which can directly use the rainwater purified by the rainwater purification device 16 for vehicle washing or green plant irrigation, realizing the efficient reuse of rainwater resources; excess rainwater is discharged to the municipal rainwater pipe through the rainwater pressure pipe 18.

[0040] The processing unit is preset with thresholds and safety values. It is connected to the water level sensor 5, vehicle information reading device 19, vehicle carrier 27, automatic water inlet gate 10, emergency control gate 11, submersible pump 24, lift pump 15, pipeline pressure detector, and solenoid valve. The processing unit is also connected to a communication unit. When the vehicle carrier is moved to the upper parking level, the processing unit controls the communication unit to send vehicle movement information to the owner's mobile phone based on the acquired owner's communication information, allowing the owner to quickly know the vehicle's movement status. The processing unit can be configured as a central processing unit, possessing calculation and processing functions, and can be implemented using existing known CPU chips, which will not be elaborated further here. In this embodiment, the processing unit and communication unit are physically located within the uppermost high-level parking level.

[0041] like Figure 8 As shown, a control method for a dual-purpose underground parking garage for flood prevention and control is used to control the aforementioned dual-purpose underground parking garage for flood prevention and control. The method operates according to the following steps: S100: When parking begins, the processing unit assigns a vehicle carrier 27 to the vehicle to be parked and obtains the identity information of the vehicle carrier 27. S200: Within the vehicle storage and retrieval space 21, the vehicle carrier 27 engages with the vehicle carrier 33 of the vehicle transport unit. S300: After the vehicle to be stored arrives at the vehicle carrier 27, the vehicle information is read by the vehicle information reading device to obtain the vehicle information; S400: The processing unit associates the vehicle information with the identity information of the assigned vehicle platform 27, assigns a parking location information to the current vehicle platform 27, and then controls the vehicle carrier 33 of the vehicle transport unit to transport the vehicle platform 27 carrying the corresponding vehicle to the corresponding normal parking level along the vertical guide rail 3. S500: The vehicle carrier 27 is separated from the vehicle carrier 33. The vehicle carrier 27 moves along the transverse guide rail 4 through its own walking mechanism and then transports the vehicle into the parking platform 2 of the corresponding parking position. S600: When the processing unit determines that the water level in the parking box 1 is higher than the threshold, the following operations are performed on the vehicles in the normal parking layer from the bottom to the top: the vehicles are transported out of the parking platform 2 by the vehicle carrier 27, and then the vehicle carrier 27 and the transported vehicles are moved along the transverse guide rail 4. Then the vehicle carrier 33 is used to transport the vehicle carrier 27 carrying the corresponding vehicle along the vertical guide rail 3 to the high-rise parking layer with available emergency parking space 7, and then the vehicle carrier 27 is used to transport the vehicle to the emergency parking space 7. The S600 design allows for the entry of external water bodies. S700: When the processing unit determines that the water level in the parking tank 1 is lower than the safe value, it executes S200~S500 sequentially for the vehicles in the emergency parking space 7 until all vehicles return to the parking platform 2.

[0042] Specifically, the parking garage allows vehicle retrieval during periods when no operations are being performed, such as... Figure 9 As shown, the steps to retrieve the car include: The processing unit receives a request from the vehicle owner, which includes at least the license plate information, and then obtains the identity information and current parking location information of the associated vehicle board 27 based on the license plate information. The vehicle carrier 27 transports the vehicle out of the parking platform 2 and positions the vehicle on the transverse guide rail 4; The vehicle carrier 33 is controlled to move along the vertical guide rail 3 to the parking level where the vehicle is located, and to engage with the corresponding vehicle carrier 27. The vehicle carrier 33 transports the corresponding vehicle platform 27 carrying the vehicle to the vehicle storage and retrieval space 21 along the vertical guide rail 3. After the vehicle leaves the storage and retrieval space 21, the corresponding vehicle carrier 27 is separated from the vehicle carrier 33 and stored in the storage slot 22 for the next use.

[0043] The above are only some of the embodiments listed in this application and are not intended to limit this application.
