Description
A BIPV parking garage with heat insulation effect Technical Field
[0001] This utility model relates to the fields of building engineering and renewable energy technology, specifically to a BIPV parking garage with heat insulation effect. Background Technology
[0002] With the increasing global emphasis on renewable energy and the ever-increasing requirements for building energy conservation, building-integrated photovoltaics (BIPV) technology has emerged and been widely used. BIPV organically combines solar photovoltaic power generation systems with buildings, installing photovoltaic modules on the roof, walls and other parts of the building. It can generate clean energy and replace traditional building materials, achieving the dual benefits of building function and energy production.
[0003] Traditional outdoor parking garages generally use simple roof structures with poor heat insulation performance, making it difficult to effectively block solar radiation and heat transfer. This deficiency is particularly noticeable in summer, often causing the interior temperature of the car to rise sharply, forcing car owners to frequently use air conditioning to maintain a comfortable environment, thereby significantly increasing energy consumption and operating costs. In addition, the widespread use of air conditioning equipment has exacerbated greenhouse gas emissions, posing a significant negative impact on the environment. Furthermore, traditional outdoor parking garages have large unused areas on the roof and inside, resulting in very low space utilization. Utility Model Content
[0004] The purpose of this invention is to provide a BIPV parking garage with heat insulation effect to overcome the shortcomings of the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A BIPV parking garage with heat insulation effect includes a steel structure frame, a vehicle-carrying assembly, a lifting assembly, a guiding assembly, and an energy storage device. The steel structure frame is divided into three or more layers (upper, middle, and lower). The top of each steel structure frame is fixedly connected to the bottom of a first BIPV panel. A second BIPV panel is fixedly installed on the front side of the steel structure frame. The energy storage device is located on the left side of the left steel structure frame. Both the first and second BIPV panels are electrically connected to the energy storage device via charging cables. A discharge line is fixedly installed on the top of the energy storage device.

[0010] The outer sides of the drums on the same side are wound with steel wire ropes that pass through two guide pulleys on the same side and extend downwards. The bottom of the steel wire ropes is fixed to the top of the lifting platform by fasteners.
[0011] The beneficial effects of this utility model are as follows: By installing BIPV panels on the top and front of the steel structure frame, they can serve as building materials, providing structural support for the entire parking garage, and also provide shade from sunlight on the top and front of the parking garage, thus providing heat insulation and reducing the internal temperature of the parking garage. With the synergistic effect of the energy storage device, the renewable energy converted from the BIPV panels can also be collected for the parking garage to consume, thereby reducing energy expenditure. In addition, with the help of the three-layer steel structure frame, more parking areas can be planned inside, improving the space utilization efficiency.

Couplings are fixedly installed on both sides of the drive shaft, and drum shafts are fixedly installed on the opposite sides of the two couplings. Two drums are respectively sleeved on the outside of the two drum shafts. Drum hubs located on the left and right sides of the same-side drums are fixedly installed on the outside of the two drum shafts.

[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0030] Example 1, as shown in Figures 1 to 6, is a BIPV parking garage with heat insulation effect, including a steel structure frame 1, a vehicle carrying assembly 2, a lifting assembly 3, a guiding assembly 4, and an energy storage device 5. The steel structure frame 1 is divided into three layers: upper, middle, and lower. The top of the steel structure frame 1 is fixedly connected to the bottom of the first BIPV panel 6. A second BIPV panel 7 is fixedly installed on the front side of the steel structure frame 1. The energy storage device 5 is located on the left side of the left steel structure frame 1. The first BIPV panel 6 and the second BIPV panel 7 are both electrically connected to the energy storage device 5 through charging cables 8. A discharge line 9 is fixedly installed on the top of the energy storage device 5. A parking and retrieval control panel 10 is fixedly installed on the front side of the steel structure frame 1.
[0031] The vehicle carrier assembly 2 includes a lower vehicle carrier platform 201 that moves horizontally, a middle vehicle carrier platform 202 that moves horizontally, and a vehicle carrier platform 203 that moves vertically.
[0032] The lifting assembly 3 includes a support base 301, a lifting motor 302, a small sprocket 303, a large sprocket 304, a drive shaft 305, and a drum 306. There are two drums 306, which are symmetrically distributed from left to right.
[0033] The guide component 4 includes four guide pulleys 401 arranged in pairs and symmetrically distributed on the left and right sides. The two sets of guide pulleys 401 are located on the front side of the two drums 306 and their centers are collinear.
[0034] On the same side, the outer side of the drum 306 is wound with steel wire rope 11 that passes through the two guide pulleys 401 on the same side and extends downward. The bottom of the steel wire rope 11 is fixed to the top of the lifting vehicle plate 203 by fasteners.
[0035] Both the first BIPV panel 6 and the second BIPV panel 7 are electrically connected to the energy storage device 5 via charging cables 8, and can store electrical energy (converting solar energy into electrical energy for storage is a conventional technical means in this field, so it will not be described in detail). The cooperation of the first BIPV panel 6 and the second BIPV panel 7 blocks sunlight from the top and front, reducing direct sunlight on vehicles in the outdoor parking garage and preventing the temperature inside the vehicle from rising. The discharge line 9 can supply power to the lifting assembly 3 and the parking and retrieval control panel 10. The lifting platform 203 is lifted by four steel wire ropes 11, forming a rectangle to ensure stability during the lifting process. This allows vehicles to be parked in three layers (upper, middle, and lower) within the steel structure frame 1, making great use of the space in the entire outdoor parking garage. The operation of the lifting assembly 3 is controlled by the parking and retrieval control panel 10.
[0036] Example 2 is a further improvement on Example 1, specifically as follows: The lifting motor 302 is fixedly mounted on the top of the support base 301. The small sprocket 303 is fixedly connected to the outside of the left output shaft of the lifting motor 302. The large sprocket 304 is located below the small sprocket 303. A chain drive is formed between the small sprocket 303 and the large sprocket 304. The drive shaft 305 is fixedly connected inside the large sprocket 304. The right side of the drive shaft 305 extends through and to the right side of the support base 301. Couplings 307 are fixedly mounted on both the left and right sides of the drive shaft 305. A drum shaft 308 is fixedly installed on the opposite sides of the shaft assembly 307. Two drums 306 are respectively sleeved on the outside of the two drum shafts 308. Drum hubs 309 located on the left and right sides of the drums 306 on the same side are fixedly installed on the outside of the two drum shafts 308. A first support frame 310 is provided on the opposite sides of the two drum shafts 308. A second support frame 311 is provided on the opposite sides of the two drums 306. The opposite sides of the two drum shafts 308 are rotatably connected to the opposite sides of the two first support frames 310 through bearings. The two drum shafts 308 are rotatably installed inside the second support frame 311 on the same side through bearings.
[0037] When the lifting motor 302 starts, it drives the small sprocket 303 to rotate via the output shaft. This, in turn, drives the large sprocket 304 to rotate during chain transmission. The rotation of the large sprocket 304 then drives the drive shaft 305 to rotate. Under the action of the couplings 307 on both sides of the drive shaft 305, the drum shafts 308 on both sides rotate. With the cooperation of the first support frame 310 and the second support frame 311, the drum shafts 308 are made more stable during rotation, making the drum 306 rotate more stably during the winding of the wire rope 11, thus ensuring normal operation.
[0038] Example 3 is a further improvement based on Example 1, and it is as follows: The steel structure frame 1 is assembled from steel structure columns 101 and steel structure beams 102. Hot-rolled angle steel 12 is fixedly installed on the left, right and rear sides of the steel structure frame 1.
[0039] The outdoor parking garage is assembled from multiple steel structural columns 101 and steel structural beams 102, forming a three-story structure. The stability of the entire steel structure frame 1 is enhanced by the action of hot-rolled angle steel 12.
[0040] Example 4 is a further improvement based on Example 3, and its specific details are as follows: There are five lifting components 3 arranged in a three-upper-two-lower configuration inside the steel structure frame 1. The upper support base 301, the first support frame 310 and the second support frame 311 are all fixedly installed to the top of the upper steel structure beam 102 by fasteners. The middle support base 301, the first support frame 310 and the second support frame 311 are all fixedly connected to the top of the translational middle vehicle platform 202.
[0041] Multiple lifting components 3 at different locations enhance the adjustability of vehicle lifting in the entire parking garage, and also make it easier to select a suitable parking position according to the actual situation.
[0042] Example 5 is a further improvement based on Example 1, and it is as follows: There are five guide components 4 arranged in a three-upper-two-lower configuration inside the steel frame 1, and there are two guide pulleys 401 inside the middle guide component 4 arranged symmetrically from left to right.
[0043] The middle layer lifting component 3 extends downwards from the outside of the drum 306, and the steel wire rope 11, together with the steel wire rope 11 passing through the guide pulley 401 on the front side, also forms a rectangular distribution pattern, which facilitates the subsequent lifting of the lifting platform 203.
[0044] Example 6 is a further improvement based on Example 3, and is as follows: Two placement seats 13 are fixedly installed on the opposite sides of the upper adjacent steel structure beams 102 and are symmetrically distributed front and back. The upper guide pulleys 401 are fixedly installed on the top of the corresponding placement seats 13, and the middle guide pulleys 401 are fixedly installed on the top of the translational middle vehicle plate 202.
[0045] The upper guide pulley 401 is installed on the placement seat 13 to ensure that the center of the guide pulley 401 and the drum 306 are collinear, so that the guide pulley 401 remains stable during the lifting process of the wire rope 11. The middle guide pulley 401 is installed on the top of the translation middle layer vehicle plate 202 to ensure that the center of the drum 306 at the corresponding position in the middle layer is collinear with the center of the middle layer vehicle plate 202.
[0046] Example 7 is a further improvement based on Example 4, and it is as follows: There are two lower-level vehicle carriers 201 and two middle-level vehicle carriers 202, which are respectively distributed on the upper and middle sides of the steel structure frame 1. There are five lifting vehicle carriers 203, which are respectively located below the five lifting components 3.
[0047] It can be adapted to the use of multiple lifting components 3 to improve the utilization rate of the internal space of the entire steel structure frame 1.
[0048] Example 8 is a further improvement based on Example 2, and its specific details are as follows: An elastic washer 14 located outside the drive shaft 305 is fixedly installed on the left side of the large sprocket 304.
[0049] The elastic washer 14 can provide a certain buffering and clamping effect on the connection between the large sprocket 304 and the drive shaft 305 through its elasticity, thereby helping to prevent chain bite problems caused by excessive slack or vibration during the transmission process and ensuring the smooth operation of the chain drive system.
[0050] Working principle:
[0051] Steel structural columns 101 are first installed on the front and rear sides, and then connected by steel structural beams 102 to form a steel structural frame 1. The rear steel structural column 101 is higher than the front steel structural column 101, which facilitates the inclined installation of the first BIPV panel 6, enhances the solar energy conversion of the first BIPV panel 6, and improves the stability of the entire steel structural frame 1 in conjunction with the second BIPV panel 7 on the front side and the hot-rolled angle steel 12 on the left, right and rear sides. When it is necessary to stop, the lifting components 3 at different positions are controlled according to the actual situation, and the lifting motor 302 is started, which drives the small sprocket 303 to rotate through the output shaft. During chain drive, the large sprocket 304 rotates, which in turn drives the drive shaft 305 to rotate. Under the action of the couplings 307 on both sides of the drive shaft 305, the drum shafts 308 on both sides rotate. With the cooperation of the first support frame 310 and the second support frame 311, the drum shafts 308 are more stable during rotation, making the drum 306 rotate more stably during the winding of the wire rope 11, maintaining normal use. The winding of the wire rope 11 drives the lifting platform 203 to rise and fall, thereby driving the vehicle located on the lifting platform 203 to rise and fall, thus making use of the space, or directly stopping below.
[0052] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
