Description
Technical Field
[0001] The utility model relates to the technical field of safety facilities, and more specifically, to a locking device for a protective net door of a cooling tower. Background Art
[0002] As a key device for reducing water temperature, cooling towers play a vital role in the hot summer. As the temperature rises, cooling towers need to operate continuously and efficiently to ensure the normal operation of various equipment. However, this continuous operation will also make it easy for dust and debris to accumulate inside the cooling tower, which will affect its cooling effect and operating efficiency. Therefore, it is particularly important to clean and maintain the cooling tower regularly.
[0003] In the past, the surrounding of the cooling tower usually adopts a closed and sealed design, and uses screws and other fixings to tightly connect with other parts of the cooling tower frame. Although this design ensures the integrity and sealing of the cooling tower, it brings considerable trouble when cleaning and maintaining it. The staff needs to spend a lot of time and energy to remove the protective baffles in order to enter the cooling tower for operation. This not only increases the working time, but also increases the difficulty and complexity of the operation, and reduces the work efficiency. In order to solve this problem, a solution is proposed to add protective doors and door locks to the north and south sides of the cooling tower. This design not only retains the original sealing and integrity of the cooling tower, but also makes cleaning and maintenance work more convenient and efficient. When the cooling tower needs to be cleaned or maintained, the staff only needs to open the protective doors on the north and south sides to easily enter the cooling tower, without spending a lot of time removing the protective baffles, which greatly reduces the working time, improves the work efficiency, and makes the cleaning and maintenance of the cooling tower easier and simpler. In addition, the installation of door locks can further increase the safety of the cooling tower. Only authorized personnel can open the protective doors to enter the cooling tower, effectively preventing unauthorized personnel from breaking in and destroying it. This helps protect the equipment and facilities inside the cooling tower and ensures its safe and stable operation. Utility Model Content
