This paper analyzes the relevant research on push-button quick-release latch, and presents the dynamic model of a typical push-button latch based on a planar four-bar linkage mechanism. ADAMS software was used to simulate the opening and closing performance of the typical push-button latch. The influence of push angle, push position, push speed and push acceleration on the actual opening force measurement of the product was analyzed, as well as the preload test method of the push-button latch, and the sensor method was recommended to measure the preload force, and tested by experiments. Moreover, this paper analyzes the durability test method of push-button latch, uses the sensor to detect the change of opening and closing force in the process of durability test and studies the durability test of typical products.

Under the call of ecological civilization construction, the internal provincial evaluation of power companies has also been gradually advanced. Taking into account the vast territory of my country, the large-scale power system, and the complex structure, power grids at all levels have differences in areas such as jurisdiction area, climatic conditions, power grid scale, and technical level. Under this premise, if a reasonable index system and evaluation method are not formulated, and a unified evaluation index system is adopted for each region, it may not be possible to achieve a relatively fair evaluation of the regional power grid. Under this condition, it is difficult to exert the guidance of the evaluation method on the green development of the power grid. In this paper, taking into account the differences that exist between all levels of power grids in our country, the hierarchical cluster method is used to cluster them.

With the development of ecological civilization construction and regional coordinated development strategy in China, to adapt to the development trend of urban agglomeration, the energy structure will be adjusted and upgraded accordingly. The energy structure has gradually changed from fossil energy to diversified supply mode. The integrated energy system of urban agglomeration will coordinate with energy planning, operation, management and other links, and realize the linkage and complementarity of multiple energy sources. In this context, it is necessary to carry out a systematic analysis of the comprehensive energy system of urban agglomerations. This paper analyzes the connotation, characteristics and function mechanism of comprehensive energy system of urban agglomeration, and constructs a set of evaluation index system. These research ideas and methods can be applied to the scenarios of energy development, utilization and management that adapt to the development of urban agglomeration, and provide scientific analysis tools for energy system management and evaluation.

This study compares and analyzes the environmental management cases of well-known foreign energy and power companies, and investigates their environmental management operation modes, environmental protection measures and environmental management performance. Based on the survey data, this paper puts forward the main problems existing in the environmental management of China’s energy and power enterprises. The results show that the world-famous energy and power companies have clear environmental protection strategic goals, first-class environmental protection talents and continuous environmental protection technology. Innovative environment protection abilities include extending the pollution prevention chain, innovation waste recycling and reusing methods, carrying out the research of carbon capture and storage technology, and focusing on protecting biodiversity. In contrast, the environmental management systems of some domestic power enterprises are not compatible with the rapid development of productivity, therefore, an innovative environmental management model is needed.

Coal-fired thermal power units emit a large amount of air pollutants, which has aggravated air pollution in China and seriously affected people’s life and health. Therefore, it is necessary to formulate more reasonable emission reduction plans for thermal power units in China, so as to reduce air pollution. In order to maximize the comprehensive benefit of thermal power emission reduction, this paper put forward a method of optimizing the emission reduction scheme of thermal power units based on linear programming, and calculated the emission reductions in future.
