Description

Technical Field

[0001] The utility model relates to the technical field of water circulation in hydrogen stations, in particular to circulating water equipment in hydrogen stations. Background Art

[0002] The circulating water equipment of hydrogen stations plays a vital role in hydrogen stations. Its main function is to circulate and cool various equipment and systems in hydrogen stations. This equipment usually includes key components such as circulating water pumps, coolers, filters and water tanks.

[0003] First, the circulating water pump draws water from the water tank and delivers it to the equipment and systems that need to be cooled through pipes. During this process, the circulating water absorbs the heat generated by the equipment and systems, causing the water temperature to rise. In order to maintain the cooling effect of the circulating water, the cooler is responsible for lowering the temperature of the circulating water. In this way, the cooled circulating water can be delivered to the equipment and systems that need to be cooled again, forming a continuous circulation process.

[0004] However, during the installation of hydrogen stations, especially in narrow and long areas, the installation of circulating water equipment may face some challenges. Due to space constraints, the size and weight of the equipment may make installation very difficult. In addition, complex geographical environments, such as undulating terrain and high groundwater levels, may further increase the difficulty and cost of installation.

[0005] In addition to installation issues, the cooling effect of circulating water equipment in narrow and long areas may also be affected. Due to spatial layout restrictions, it may be difficult to effectively arrange cooling pipes and equipment, thus affecting the normal operation of electrical equipment. At the same time, if the geographical environment is not conducive to water circulation, such as insufficient water sources or poor water quality, the cooling effect of circulating water equipment may also be reduced.

[0006] Therefore, during the planning and construction of hydrogen stations, it is necessary to fully consider the installation and operating environment of circulating water equipment to ensure that it can play its greatest role and provide strong support for the normal operation of hydrogen stations. Utility Model Content

[0007] The main purpose of the utility model is to provide a hydrogen station circulating water device, which can effectively solve the problems raised in the background technology.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] A hydrogen station circulating water device comprises a base, a support frame, a water circulation pipe and a circulation pipe control valve, wherein the water circulation pipe is installed on the base through a plurality of support frames, and the circulation pipe control valve is installed on the water circulation pipe;

[0010] The tail of the water circulation pipe is connected with a mounting pipe, and a circulation pump is installed on the mounting pipe through a docking pipe. The mounting pipe is connected with a fixing seat through a vertical frame, and the fixing seat is installed on the base through fasteners;

[0011] A plurality of first meters are installed on the water circulation pipe to detect the flow rate and water temperature by using different first meters. Branches and second meters are installed on different docking pipes. The water flow of the water circulation pipe is extended to the electrical equipment end of the hydrogen station through the branches for heat and cold exchange. Different second meters detect the flow rate and water temperature at the mounting pipe and the docking pipe. The mounting pipe and the docking pipe are vertically distributed in a narrow area through the vertical frame and are reasonably distributed in the hydrogen station.

[0012] As a preferred solution of the present application, the cross-section of the water circulation pipe is designed in a "mouth" shape. Four support frames are distributed at the four corners of the water circulation pipe. The support frames are installed on the water circulation pipe through clamps, and a rubber sleeve is provided at the connection between the water circulation pipe and the clamp;

[0013] As a preferred solution of the present application, a plurality of circulation pipeline control valves are distributed at the inlet and outlet of the water circulation pipe. The mounting pipe and the water circulation pipe are connected through flanges and bolts, and a rubber ring is provided at the connection. The docking pipe and the mounting pipe are fixed through flanges and bolts;

[0014] As a preferred solution of the present application, the circulation pump is fixed on the docking pipe through flanges and bolts, and the circulation pump is installed on the vertical frame through a bracket;

[0015] As a preferred solution of the present application, the cross-section of the fixing seat is designed in a "day" shape, and the fixing seat is fixed on the base through bolts. A plurality of vertical frames are distributed at the corners of the fixing seat. The cross-section of the vertical frame is designed in an "L" shape, and the vertical frame fixes the mounting pipe and the docking pipe through a clamp;

[0016] As a preferred solution of the present application, the second meter and the branch pipe are hermetically connected to the docking pipe, and the first meter and the circulation pipeline control valve are hermetically connected to the water circulation pipe.

[0017] Compared with the prior art, the present utility model has the following beneficial effects:

[0018] In the present utility model, in order to better adapt to the layout and space limitation inside the hydrogen station, we installed the mounting pipe and the branch pipe. This design is particularly suitable for narrow areas. Through reasonable pipeline layout, we have successfully achieved efficient water circulation and cooling effects in a limited space.

[0019] The design of the mounting pipe not only helps to improve the efficiency of water circulation, but also ensures the smooth flow of water during the circulation process. By guiding the water to the circulation pump, we reduce the energy loss and frictional resistance, thereby improving the overall working efficiency.

[0020] The installation of branch pipes enables the circulating water to be more evenly distributed to the electrical equipment end of the hydrogen station, ensuring that each part can be adequately cooled. This uniform distribution helps reduce equipment failures caused by local overheating, thereby improving the stability and reliability of the system.

[0021] In addition, the layout design of the additional pipes and branch pipes also brings convenience to the maintenance and management of the equipment. In narrow and long areas, through reasonable pipeline layout and clear markings, we can more easily identify and solve problems, thereby reducing maintenance time and costs.
