Description

Technical Field

[0001] This utility model relates to the field of cement production and processing technology, specifically to a photovoltaic fence system and preheater for cement plants. Background Technology

[0002] Cement production, as a high-energy-consuming industry, requires a large amount of electricity and heat. Traditional cement plants mainly rely on coal or fossil fuels for power, resulting in high energy costs and significant emissions of pollutants such as carbon dioxide and sulfur oxides. With the advancement of global carbon reduction policies, the cement industry faces severe environmental pressure and the need for energy transition.

[0003] Photovoltaic power generation is a new energy-saving and consumption-reducing measure adopted by existing cement plants. As major electricity consumers, cement plants can achieve self-consumption of their electricity if they have the conditions to build a photovoltaic power generation system. However, there are several factors that restrict the construction of photovoltaic power stations in cement plants:

[0004] 1. Ground resources are scarce; if a large area of ​​ground resources is used for the deployment of photovoltaic systems, the output will be low.

[0005] 2. Cement plants contain tall buildings such as preheaters (over 100 meters high) and cement silos, which severely obstruct the roof and ground, greatly reducing the power generation efficiency of photovoltaic systems installed on the roof and ground.

[0006] Therefore, there is an urgent need to provide a photovoltaic fence system for cement plants to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to overcome the problems of inconvenience in deploying photovoltaic systems in cement plants and low output and power generation efficiency in existing technologies. It provides a photovoltaic fence system and preheater for cement plants. The photovoltaic fence system for cement plants has a simple structure, is easy to assemble and disassemble, can achieve high-efficiency power generation without obstruction, greatly improves the utilization rate of electrical energy, saves the factory's electricity costs, and contributes to environmental protection.

[0008] To achieve the above objectives, this utility model provides a photovoltaic fence system for cement plants. The photovoltaic fence system for cement plants includes a photovoltaic fence installed on the upper part and / or top of tall equipment in cement plants. The photovoltaic fence consists of multiple photovoltaic modules arranged in sequence, connected end to end, and set to face south or slightly south to receive sunlight. The photovoltaic modules are connected to the low-voltage switchgear of the power room of the tall equipment via an inverter.

[0009] Preferably, the photovoltaic fence is fixed to the structural platform or side wall of the tall equipment by steel beams and keels.

[0010] Preferably, the photovoltaic fence is provided with multiple diagonal braces that connect the structural platform or sidewalls evenly distributed along its length.

[0011] Preferably, each photovoltaic module is connected to the keel at the top and bottom by multiple edge clamps.

[0012] Preferably, the keel is also provided with a medium pressure block, which is configured to connect and fix two adjacent photovoltaic modules.

[0013] Preferably, the height of the photovoltaic fence is greater than or equal to 1.2 meters.

[0014] Preferably, the height of the photovoltaic fence is 1.2-1.5 meters.

[0015] The second aspect of this utility model provides a preheater, which includes a preheater body and a photovoltaic fence system for cement plants, as described above, disposed on a platform at a high position on the preheater body.

[0016] Preferably, the photovoltaic fence system for cement plants is connected to the low-voltage switchgear in the power room of the preheater body via an inverter.

[0017] According to the above technical solution, photovoltaic (PV) fences are installed on the upper part and / or top of tall equipment in cement plants. Due to the height of the equipment, multiple PV modules are arranged sequentially, connected end-to-end, and oriented towards the south or slightly south to receive sunlight. This allows the PV modules to generate electricity efficiently and without obstruction, maintaining a long-term power generation state. Simultaneously, the PV fences installed at high altitudes can also serve as fencing for the tall equipment, improving safety during manual maintenance work at heights. Furthermore, the PV modules can be connected to the low-voltage switchgear in the power room of the tall equipment via inverters for convenient power consumption. Attached Figure Description

[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "top," and "side" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0025] See Figure 1 This utility model provides a photovoltaic fence system for cement plants. The photovoltaic fence system for cement plants includes a photovoltaic fence 1 installed on the upper part and / or top of the tall equipment in the cement plant. The photovoltaic fence 1 consists of multiple photovoltaic modules 2 arranged in sequence, connected end to end, and set to face south or slightly south to receive sunlight. The photovoltaic modules 2 are connected to the low-voltage switchgear of the power room of the tall equipment through an inverter.

[0026] Through the above technical solution, the photovoltaic fence 1 is installed on the upper part and / or top of the tall equipment in the cement plant. Due to the height of the equipment, multiple photovoltaic modules 2 are arranged sequentially, connected end to end, and oriented towards the south or slightly south to receive sunlight. In this way, the photovoltaic modules 2 can generate electricity efficiently and without obstruction, maintaining a long-term power generation state. At the same time, the photovoltaic fence 1, installed at a high position, can also be used as a fence for the tall equipment, improving the safety of manual maintenance work at height. Furthermore, the photovoltaic modules 2 can be connected to the low-voltage switchgear in the power room of the tall equipment via an inverter for easy power consumption.

[0027] In this embodiment, when setting up the photovoltaic fence system for the cement plant, in order to take into account the requirements of stability, wind pressure resistance, corrosion resistance and convenient installation, it is preferable to fix the photovoltaic fence 1 to the structural platform or side wall of the tall equipment through steel beams and keels.

[0028] In practical use, photovoltaic panels generate enormous lateral thrust under strong winds. To disperse and transfer the wind force to the main beam and foundation, and to prevent the support structure from twisting or overturning, preferably, multiple diagonal braces 3 (see [reference]) are evenly distributed along the length of the photovoltaic fence 1 to connect the structural platform or sidewalls. Figure 2 Thus, when the longitudinal or transverse span of the photovoltaic array is large, the main beam and column may buckle due to their own weight or snow load. However, the diagonal brace 3 can significantly improve the geometric invariance of the structure. The diagonal brace 3 connects the main beam and the column, reduces the bending moment stress at the connection, and avoids bolt loosening or weld cracking.

[0029] In this embodiment, preferably, such as Figure 3As shown, each photovoltaic module 2 is connected to the keel via multiple edge clamping blocks 4 at its top and bottom. More preferably, the keel also has a central clamping block 5, which is configured to connect and fix two adjacent photovoltaic modules 2. The clamping blocks evenly press the photovoltaic module frame, avoiding localized stress concentration and preventing microcracks in the glass or cells. Simultaneously, the clamping blocks, once locked to the keel, form a rigid connection, resisting the negative pressure suction of strong winds and preventing the modules from being overturned. Furthermore, compared to bolt-drilled fixation, the clamping blocks allow for slight displacement, effectively mitigating mechanical stress caused by vibration.

[0030] In this embodiment, based on considerations of personnel safety, it is preferred that the height of the photovoltaic fence 1 is greater than or equal to 1.2 meters.

[0031] Furthermore, to avoid the overall height of the photovoltaic fence system used in the cement plant being too high, which would obstruct the observation of the operation of the tall equipment from the ground and facilitate the early detection of machine failures and potential fire hazards, the height of the photovoltaic fence 1 is preferably 1.2-1.5 meters.

[0032] Another aspect of this utility model provides a preheater, which includes a preheater body and the aforementioned photovoltaic fence system for cement plants, mounted on a platform high above the preheater body. Specifically, the photovoltaic fence system for cement plants is connected to the low-voltage switchgear in the power room of the preheater body via an inverter. Thus, utilizing the steel platform high above the preheater, a photovoltaic fence is installed on the south or slightly south side of the platform, allowing the photovoltaic modules 2 to generate electricity unobstructed, while also serving as a fence for the preheater. The preheater fence is fixed to the original structural platform using steel beams and keel components. Furthermore, the photovoltaic modules 2 can be transported upwards via the preheater's elevator, facilitating transportation and installation. Simultaneously, the photovoltaic modules 2 can be connected to the low-voltage switchgear in the preheater's power room via the inverter for convenient power consumption.

[0033] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
