Description

Technical Field

[0001] The present invention relates to the technical field of mechanical parking equipment, and specifically to an overhead three-dimensional parking unit module suitable for the reconstruction of old residential areas, which integrates photovoltaic power generation, ecological greening and intelligent control functions. Background Art

[0002] With the acceleration of urbanization, the problem of parking difficulties in old communities has become increasingly prominent. Since early planning did not fully consider the demand for the growth of motor vehicles, these communities generally have problems such as cramped space, lack of green space, and aging infrastructure. Traditional parking solutions are difficult to adapt to their special environment. The following analyzes the limitations of existing parking solutions from a technical perspective:

[0003] 1. Problems with traditional stereo garages

[0004] Poor spatial adaptability: Existing multi-story parking garages (such as lifting and transverse moving, aisle stacking) require a continuous and flat site (length × width ≥ 20m × 6m), while the distance between buildings in old residential areas is usually less than 10 meters and the shapes are irregular, resulting in a low equipment installation rate.

[0005] High energy consumption and high cost: Traditional equipment relies on high-power motors (above 7.5kW) to drive, with an average daily electricity consumption of 1.2-1.8kWh per parking space, and the steel structure usage is as high as 180-220kg per parking space. The construction cost is about 60,000-80,000 yuan per parking space, plus the subsequent maintenance costs, making the construction and operation costs relatively high.

[0006] Low ecological compatibility: On the one hand, the construction of a multi-story parking garage will occupy the existing activity and green space in the community. On the other hand, the metal structure will hinder ventilation and lighting. At the same time, the visual image of the garage is incompatible with the community environment.

[0007] Inconvenient parking: The structure and space size of ordinary stereo garages make it very inconvenient for vehicles to enter and exit the parking, which is very easy to cause scratches, seriously affecting safety and user experience. In addition, the conventional stereo garage's circular storage and retrieval method not only reduces efficiency, but is also prone to equipment failure.

[0008] 2. Disadvantages of ground parking lots

[0009] Low land utilization rate: Ground parking requires about 12-15 square meters per parking space, which will lead to the occupation of a large amount of green space, activity and walking space, reduce the quality of the original community environment, and fail to meet the requirement of "the greening rate of old district reconstruction should not be less than 25%" in the "Urban Residential Area Planning and Design Standard" (GB50180-2018).

[0010] Prominent safety hazards: ground vehicles parked on the road make the width of the fire passage seriously insufficient, resulting in obstruction of the passage of fire trucks and ambulances in emergency situations.

[0011] Extensive management: relying on manual registration or ground lock management, the parking space turnover rate is less than 2 times / day, and disputes frequently occur during peak hours.

[0012] 3. Deficiencies of existing intelligent parking systems

[0013] High dependence on energy: Automated garages (such as AGV robot parking) require continuous supply of city electricity, but the load capacity of the power grid in old residential areas is limited, and equipment operation can easily cause tripping.

[0014] Low degree of modularity: Most existing parking methods use fixed structures, which cannot dynamically adjust the parking height and number of floors according to the distance between buildings. In addition, they are not easy to install and connect with each other.

[0015] Lack of ecological integration: The three-dimensional parking function is single and is not combined with vertical greening, rainwater circulation and other systems, which not only affects the visual image of the community, but also lacks ecological benefits.

[0016] 4. Summary of technical pain points

[0017] The existing technology has the following core defects:

[0018] Poor layout flexibility: unable to adapt to the current situation of tight land use and large number of irregular spaces in old residential areas, large-scale demolition of existing facilities is required during renovation;

[0019] Unsustainable energy: There is a sharp contradiction between high-energy consumption equipment and the carrying capacity of the community power grid;

[0020] Single function: It only solves parking needs, without taking into account the optimization of community ecology and residents' activity space.

[0021] 5. Market demand and technology gap

[0022] There are about 170,000 old residential areas in China that need to be renovated, with a potential demand for more than 50 million parking spaces, but the adaptation rate of existing solutions is less than 15%. The market urgently needs a solution with the following features:

[0023] Strong spatial adaptability: small footprint, supports flexible and rapid deployment in irregular sites;

[0024] Energy self-circulation: The photovoltaic system meets most of the operating energy needs and reduces the cost of use;

[0025] Ecological integration: realize the multifunctional integration of parking, greening and ecological services;

[0026] Convenience of use: Vehicle parking and access are convenient and safe, reducing the possibility of scratches.

[0027] Conclusion: Due to structural, energy and ecological compatibility defects, the existing technology is difficult to meet the needs of three-dimensional parking renovation in old communities. This invention specifically proposes a three-dimensional parking unit module solution, which fills the above technical gaps through overhead structure design, photovoltaic energy storage integration and intelligent dynamic regulation, and provides an innovative parking path for the renovation of high-density old communities. Summary of the invention

[0028] Purpose of the Invention

[0032] Support column assembly: It consists of two groups of steel structure columns, each group is divided into two columns, the left and right spacing (short axis direction) of the two columns is 800-1200mm, and the spacing between the long sides (long axis direction) of the groups is 5100-5400mm, which meets the length dimension requirements of small motor vehicles. The left and right gaps between the two columns are equipped with cable channels and vertical lifting systems (including brushless motors, Kevlar cables and gravity balance weights); 4 vertical slide rails are arranged on the inner side of the columns to meet the vertical movement of the control lifting platform system; the installation base is set 3000mm from the ground to the left and right of the columns to connect with the parking unit system to meet the installation requirements of the parking space; the top of the column is equipped with a folded line or curved photovoltaic roof and battery to solve the energy supply and top shape problems when storing and retrieving vehicles; the height of the column is related to the size of the site space, but it should be at least 8m to meet the needs of two-story parking.

[0033] Parking unit system: includes parking platform and vertical greening troughs around it; the surface of the parking platform is equipped with anti-skid coating, tire limiter and PSD position sensor to determine the vehicle position and prevent the vehicle from sliding; the parking platform adopts steel structure and is connected to the steel structure column mounting base by welding or bolts; the short side width of the parking platform is at least 2400mm, and the long side is flush with the long axis direction of the steel structure column to meet the parking needs of motor vehicles.

[0034] Intelligent lifting platform system: including lifting platform, horizontal moving carrier platform, horizontal moving track and laser positioning target; the width of the lifting platform is 2100mm, and the length is adapted to the long axis direction of the steel structure column; the horizontal moving carrier platform is connected to the lifting platform through a retractable horizontal moving track and can slide left and right; the horizontal moving carrier platform has a dynamic lifting function, and a hydraulic support is installed at the connection between the platform and the horizontal moving track, which can automatically adjust the height of the hydraulic support according to the height of the chassis of the parked vehicle (adjustment range 0-200mm). The lifting platform is equipped with an anti-skid coating and a tire limiter to prevent the vehicle from sliding; the ground vehicle is parked on one side of the steel structure column so that its long side is parallel to the long side of the lifting platform; the horizontal moving track drives the horizontal moving carrier platform to extend and move to the lower part of the vehicle, and then the hydraulic support is lifted, so that the horizontal moving carrier platform can lift the lower steel beam of the vehicle, so that the vehicle is transferred to the horizontal moving carrier platform, and the horizontal moving track drives the carrier platform and the vehicle to retract to the lifting platform, and then the hydraulic support is lowered, and the vehicle is parked on the lifting platform. The lifting load-bearing platform is lifted and driven to the height of each parking platform through the vertical lifting system. Just like transferring vehicles on the ground, the horizontal moving carrier platform extends left and right to transport the vehicles to each parking platform.

[0035] Operation control system: including lifting control module, which is installed on the steel structure column and has functions such as storage, access and stop to facilitate personnel to operate and control the vertical-horizontal coordinated movement of the vehicle; safety protection module, which is installed on the top of the steel structure column space, monitors the cable tension, structural stress and wind speed in real time, and triggers three-level braking; energy management module is combined with battery pack and set at the top of the steel structure column space to control photovoltaic power generation and energy storage; laser radar module is set at the bottom of the photovoltaic roof to control the vehicle positioning position on the intelligent lifting platform system.

[0036] Core innovations:

[0037] Modular overhead structure: The overhead structure on both sides not only reduces the ground space occupied, but also makes vehicle storage more convenient and safer. In addition, the number of parking floors (2-6 floors) and the combination of modules can be dynamically adjusted according to the size of the site.

[0038] Photovoltaic-energy storage integration: Flexible CIGS batteries generate an average of 18-25kWh of electricity per day, meeting 75% of the equipment's energy consumption needs.

[0039] Low-power lifting system: The counterweight (about 0.8 times the vehicle mass) reduces the motor load and reduces energy consumption by 40% compared to traditional equipment.

[0040] Beneficial effects:

[0041] Space efficiency: The overhead structure makes a single parking space occupy only 2.5-4.0㎡, saving 80% of the space compared with ordinary ground parking spaces.

[0042] Safe use: When the vehicle is parked, only one side is against the steel structure column, which greatly reduces the risk of scratches. At the same time, the overhead setting allows the ground space to still be used for transportation or activities.

[0043] Ecological benefits: The vertical greening system fixes 1.2 tons of carbon per unit annually, while improving the quality of life and visual image of the community.

[0044] Economic benefits: Installing a photovoltaic system and adding a counterweight to the lifting device can greatly reduce electricity consumption. BRIEF DESCRIPTION OF THE DRAWINGS
