Description

Technical Field

[0001] This utility model belongs to the field of solar energy utilization equipment, and in particular a light focusing and utilization device for concave curtain wall building plazas. Background Technology

[0002] In special architectural forms such as concave curtain walls, sunlight reflected from the curtain wall can be focused onto a specific area, causing the intensity of local light and heat radiation in that area to be several times to tens of times greater, significantly exceeding the surrounding environment, and leading to a rapid increase in local temperature. Prolonged heat focusing can severely impact people and objects in plaza areas, and may even trigger safety accidents such as fires. Current technologies are generally insufficient for effectively monitoring the degree of thermal damage to building materials and lack real-time early warning and intervention mechanisms. For example, when a part of a building is exposed to intense heat radiation, existing monitoring systems often fail to detect problems early and take appropriate protective measures, thus exacerbating the risk of thermal damage to the building.

[0003] CN201710252226.4 discloses an integrated solar energy building curtain wall application system, and CN201210023806.3 discloses a solar collector with an external parabolic reflector integrated with a building for sun tracking. By setting the building surface as a concave surface with a light-concentrating effect and installing solar collector tubes on the concave surface, solar energy can be fully utilized. However, this method has the following drawbacks:

[0004] 1. The solar collector is installed on the building surface, which makes construction difficult, especially when the building is tall. The installation of the solar collector requires working at height, which is costly and inconvenient for later maintenance.

[0005] 2. It can only be used for newly built concave curtain walls and cannot solve the defect of existing concave curtain walls causing excessively high local temperatures in the plaza due to the concentration of reflected light.

[0006] In addition to the aforementioned solar energy utilization facilities, there are various photovoltaic and solar thermal devices. These devices can adjust the angle of the heat collection elements or photovoltaic panels according to the angle of sunlight. However, they are fixed in place and cannot be moved. Furthermore, the location of the heat-gathering zone formed by the concave curtain wall reflecting sunlight changes in different seasons. Therefore, conventional photovoltaic and solar thermal devices cannot solve the problem of excessively high local temperatures in the plaza caused by the heat-gathering effect of the concave curtain wall. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a light focusing device for concave curtain wall building plazas, which can make full use of the sunlight reflected and focused by the concave curtain wall, and can move flexibly with the change of the heat gathering area to prevent the plaza material from being damaged due to excessive local temperature and reduce the risk of fire.

[0008] To solve the above problems, the technical solution adopted by this utility model is as follows: a light focusing and utilization device for concave curtain wall building plaza, including a mobile vehicle, a thermal radiation monitoring element and a controller. The mobile vehicle is equipped with a mounting frame, and a photovoltaic module is installed on the top of the mounting frame. The controller is installed on the mobile vehicle, and the thermal radiation monitoring element is connected to the controller.

[0009] Furthermore, the thermal radiation monitoring element includes an infrared imager, which is installed on buildings surrounding the plaza and wirelessly connected to the controller.

[0010] Furthermore, the square is provided with multiple parallel first reference lines and multiple parallel second reference lines. The first reference lines are perpendicular to the second reference lines, and the second reference lines form a reference grid. Each first reference line is marked with a first mark, and each second reference line is marked with a second mark. The mobile vehicle is provided with an identification mechanism for identifying the first and second marks.

[0011] Furthermore, the first marker is a number, and the second marker is a letter.

[0012] Furthermore, the identification mechanism is a camera element.

[0013] Furthermore, the first reference line and the second reference line are plastic films pasted on the ground.

[0014] Furthermore, the first reference line and the second reference line are layers of paint applied to the ground.

[0015] Furthermore, a photothermal assembly is provided on the top of the mounting bracket.

[0016] The beneficial effects of this invention are as follows: Throughout the day, the angle at which sunlight strikes the concave curtain wall changes continuously. Therefore, the area of ​​strongest radiation formed by the reflection and focusing of the concave curtain wall also moves constantly. This invention can utilize thermal radiation monitoring elements to monitor the area of ​​strongest radiation formed by the reflection and focusing of the concave curtain wall in real time. Based on the monitoring results, the mobile vehicle can be moved to the area of ​​strongest radiation in the plaza, allowing the photovoltaic modules on the mobile vehicle to receive the strongest radiation and convert solar energy into electrical energy, thus achieving effective utilization of high-intensity radiation. Simultaneously, after absorbing high-intensity radiation, the photovoltaic modules can prevent the radiation from directly affecting the plaza ground, preventing excessively high local temperatures that could damage plaza materials and reducing the risk of fire.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] This utility model relates to a light focusing device for concave curtain wall building plazas, such as... Figure 1 As shown, the device includes a mobile vehicle body 1, a thermal radiation monitoring element 4, and a controller 11. A mounting frame 10 is provided on the mobile vehicle body 1, and a photovoltaic module 2 is provided on the top of the mounting frame 10. The controller 11 is installed on the mobile vehicle body 1, and the thermal radiation monitoring element 4 is connected to the controller 11.

[0022] The thermal radiation monitoring element 4 is used to determine the location and variation pattern of the strongest radiation area formed by the reflection and focusing of sunlight from the concave curtain wall building on the plaza, in order to find the strong radiation area on the plaza and make use of solar radiation. In this utility model, the criterion for judging the strongest radiation area is: the area with radiation intensity significantly higher than other areas of the plaza. There are three types of radiation that the plaza may receive: the first is only direct sunlight, the second is only reflected light from the concave curtain wall 100, and the third is both direct sunlight and reflected light from the concave curtain wall 100.

[0023] The mobile vehicle body 1 is a freely movable vehicle body, which can adopt various existing automated moving robots or vehicle structures. The photovoltaic module 2 converts solar energy into electrical energy to power surrounding electrical equipment. Simultaneously, a solar thermal module 3 is installed on the top of the mounting frame 10. The solar thermal module 3 converts solar energy into heat energy, which can heat cold water and provide hot water to surrounding buildings. This utility model combines the photovoltaic module 2 and the solar thermal module 3 to fully utilize solar energy. Some plazas will have food stalls offering snacks, drinks, and other goods to nearby people. This utility model can also use the mobile vehicle body 1 as a food cart, selling snacks and drinks while simultaneously generating electricity and producing hot water using solar energy.

[0024] The controller 11 can use existing technologies such as conventional PLCs, and can receive the detection signal from the thermal radiation monitoring element 4 and control the mobile vehicle 1 to automatically move to the strong radiation area.

[0025] This invention can monitor the radiation intensity of each area of ​​the plaza in real time, flexibly adjust the position of the mobile vehicle 1 to ensure that the mobile vehicle 1 is always in the strongest radiation area, improve the power generation of the photovoltaic module 2 and the hot water supply of the solar thermal module 3, and at the same time avoid the reflected light from the concave curtain wall from directly acting on the plaza ground, which would cause the local temperature of the plaza ground to be too high, prevent damage to the plaza ground material, and reduce the risk of fire.

[0026] A solar radiation tracking and analysis system can employ components such as light sensors, but these sensors can only detect localized light intensity. To achieve large-scale monitoring of the plaza, the thermal radiation monitoring element 4 of this invention includes an infrared imager. The infrared imager is installed on buildings surrounding the plaza and wirelessly connected to the controller 11. The infrared imager can capture thermal radiation images of various areas of the plaza to obtain the temperature distribution in different areas. Installed on buildings around the plaza at a suitable height, the infrared imager covers a wide detection area. Setting up 1 to 4 infrared imagers 4 around each plaza allows for monitoring of the entire plaza and enables remote monitoring. The infrared imager 4 acquires infrared images within its monitoring range and transmits them to the controller 11. Based on the infrared images of the plaza, the controller 11 can determine the area with the highest ground temperature within the monitoring area, identifying the area with a significantly higher temperature than the surrounding area as the strongest radiation zone.

[0027] To facilitate the stable movement of the mobile vehicle 1 to the area of ​​strongest radiation, it can be mounted on a pair of transverse tracks, allowing it to move along them. The ends of the transverse tracks are mounted on longitudinal tracks, which are fixed to the ground and perpendicular to the transverse tracks. The transverse tracks are connected to a displacement drive mechanism that propels them along the longitudinal tracks. However, this method requires track construction, which damages the plaza surface, resulting in high construction costs and requiring a significant amount of plaza space. Furthermore, due to the large area of ​​the plaza, it is difficult to accurately calculate the relative position of the mobile vehicle 1 to the area of ​​strongest radiation without a reference point, making it difficult to move the mobile vehicle 1 accurately and quickly to the area of ​​strongest radiation.

[0028] like Figure 2 As shown, this utility model sets up multiple parallel first reference lines 5 and multiple parallel second reference lines 6 on the square. The first reference lines 5 are perpendicular to the second reference lines 6, and the second reference lines 6 and the second reference lines 6 form a reference grid. Each first reference line 5 is provided with a first mark 7, and each second reference line 6 is provided with a second mark 8. The mobile vehicle body 1 is provided with an identification mechanism 9 for identifying the first mark 7 and the second mark 8.

[0029] The first mark 7 on different first reference lines 5 is different, and the second mark 8 on different second reference lines 6 is different, making each first reference line 5 and each second reference line 6 a unique reference line. Specifically, the first reference lines 5 and the second reference lines 6 can be made of a plastic film of a certain width, or the plastic film can be pasted on the ground; alternatively, they can be obtained by painting or drawing lines on the ground with paint. The construction is simple, low-cost, does not damage the ground, and does not hinder pedestrians from walking normally.

[0030] The first mark 7 and the second mark 8 can be sequentially arranged. For example, the first mark 7 can be a number, and the second mark 8 can be a letter. Starting from 1, the first reference lines 5 can be sequentially labeled as 1, 2, 3... and starting from A, the second reference lines 6 can be sequentially labeled as A, B, C, D... The first mark 7 and the second mark 8 can be printed or painted onto the first reference lines 5 and the second reference lines 6. The colors of the first mark 7 and the second mark 8 are different from the colors of the first reference lines 5 and the second reference lines 6.

[0031] The identification mechanism 9 can be a camera element, which can quickly identify the marks on the first reference line 5 and the second reference line 6. Multiple identification mechanisms 9 can be installed at the front, rear, left, and right edges of the moving vehicle 1. The coordinates of the moving vehicle 1 are determined based on the identification results. For example, if the identification mechanism 9 identifies the moving vehicle 1 as being between the first reference line 5 marked 3 and 4, and simultaneously between the second reference line 6 marked C and D, then the position of the moving vehicle 1 in the reference grid is determined. Simultaneously with the installation of the infrared imager 4, a camera can be installed. The camera's shooting range and angle are the same as those of the infrared imager 4. This allows for the acquisition of both infrared images and photographs of the plaza 200. The photograph of the plaza 200 includes the first reference line 5 and the second reference line 6. By overlaying the infrared image and the photograph of the plaza 200, the position of the strongest radiation area in the reference grid can be determined. Both the identification mechanism 9 and the camera are connected to the control system 22. After the signal is transmitted to the control system 22, it is processed by the control system 22. Based on the strongest radiation area and the position of the mobile vehicle 1 in the reference grid, the control system 22 plans the travel route of the mobile vehicle 1, so that the mobile vehicle 1 can move quickly and accurately to the strongest radiation area.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
