Abstract
Description
Technical Field
[0001] The utility model relates to the field of hydrogen energy, in particular to a mobile hydrogen release device. Background Art
[0002] The hydrogen system will undergo an airtightness test before leaving the factory to ensure the safety of the hydrogen system after it is actually installed on the vehicle. During the actual vehicle road test, valve failures or pipeline problems may still occur, and the entire hydrogen system will need to be discharged. In addition, during the maintenance or regular inspection of the hydrogen system, the hydrogen in the system also needs to be discharged. Because the hydrogen system is installed in different positions on the vehicle, the location of the hydrogen discharge port is also different. Furthermore, adding a similar device to each hydrogen system will increase the cost of the entire hydrogen system. The separate system configuration of components that could have been shared leads to unnecessary cost increases for the hydrogen system.
[0003] In order to solve the above technical problems, the patent document with patent number 202123370320.0 discloses a portable hydrogen release device, wherein the release buffer mechanism includes a quick-connect connector, a metal hose, a vent hand valve, a one-way valve, a flame arrester and a dustproof connector connected in sequence by corresponding pipelines.
[0004] The above solution designs the discharge pipeline into a unitized structure, making it highly portable and highly efficient in assembly and disassembly. During the on-site discharge of hydrogen from the hydrogen system, hydrogen can be discharged centrally and safely, reducing installation and connection time and improving verification efficiency and safety.
[0005] However, this solution lacks a quick-connect mechanism when connecting to the hydrogen system pipeline and cannot guarantee airtightness, posing certain safety risks. Furthermore, due to its large number of components, it requires considerable time to assemble and inspect the airtightness of the connections.
[0006] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content
[0007] The purpose of the utility model is to provide a mobile hydrogen release device to solve the problems existing in the prior art.
[0008] The above technical objectives of the present invention are achieved through the following technical solutions:
[0009] A mobile hydrogen release device includes a fixed bracket, a plurality of pipeline fixing clamps are provided on the top of the fixed bracket, and a metal hose is set on the fixed bracket through the pipeline fixing clamps; one end of the metal hose is provided with a quick plug connector, and is connected to the pipeline of the hydrogen system through the quick plug connector; the metal hose is provided with a one-way valve for ensuring one-way discharge of hydrogen; the metal hose is externally connected to a vent hand valve for emptying; a flame arrester is provided at the other end of the metal hose, and a dustproof protective cover is provided at the metal hose port outside the flame arrester.
[0010] Furthermore, the fixing bracket is a segmented structure connected by threads, which includes an upper and a lower part, the one-way valve and the vent hand valve are arranged in the upper part, and the lower part is a supporting fixing device.
[0011] Furthermore, the supporting and fixing device is a tripod, the connection between the tripod and the fixing bracket is a movable connection, and the tripod can be unfolded or folded with the connection between the tripod and the fixing bracket as a fulcrum.
[0012] Furthermore, the quick-plug connector includes a quick-plug male connector and a quick-plug female connector. The quick-plug male connector is arranged at one end of the metal hose, and the quick-plug female connector is arranged on the pipeline of the hydrogen system.
[0013] Furthermore, two pipeline fixing clamps are provided and are located in the upper part of the fixing bracket.
[0014] In summary, the present invention has the following beneficial effects:
[0015] The structure is simple and the design is ingenious. By installing a quick-connect male connector and a quick-connect female connector on the discharge device and hydrogen system pipeline respectively, an airtight connection between the two can be quickly achieved. At the same time, by installing a one-way valve and an anti-aircraft hand valve on the metal hose, rapid release can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 It is a schematic diagram of the mobile hydrogen release device described in the present utility model. DETAILED DESCRIPTION
[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to illustrations and specific embodiments.
[0018] like Figure 1As shown, the present invention proposes a mobile hydrogen release device, including a fixed bracket 1, a plurality of pipeline fixing clamps 2 are provided on the top of the fixed bracket 1, and a metal hose 3 is set on the fixed bracket 1 through the pipeline fixing clamp 2; one end of the metal hose 3 is provided with a quick plug connector 4, and the pipeline of the hydrogen system is connected to the quick plug connector 4, a one-way valve 5 for ensuring one-way discharge of hydrogen is provided on the metal hose 3, and a vent hand valve 6 for emptying is externally connected to the metal hose 3, a flame arrester 7 is provided at the other end of the metal hose 3, and a dustproof protective cover 8 is provided at the end of the metal hose 3 outside the flame arrester 7.
[0019] The vent hand valve 6 is mainly used for exhaust. Because the location of the hand valve on the whole vehicle is not easy to operate at any time or is placed in the lower part of the whole vehicle, by connecting an external vent hand valve 6, the venting can be done directly through the hand valve on the discharge device, saving operation time. The one-way valve 5 is used to ensure the flow direction of hydrogen and is only used for discharge to prevent excessive air accumulation in the pipeline. The flame arrester 7 is a safety device that can prevent unexpected situations, such as abnormal fire, from burning directly along the pipeline and causing greater risks. The dust protection cover 8 is used to prevent rainwater or debris from entering the pipeline and causing blockage.
[0020] The fixed bracket 1 is a detachable, movable bracket, divided into two parts: the upper part is a device fixed to the valve member, and the lower part is a fixed device supported on the vehicle. The disassembled tripod can be closed to save space. The upper and lower parts of the fixed bracket are connected by threads to meet normal portability requirements. The supporting and fixing device is a tripod, and the connection between the tripod and the fixed bracket 1 is a movable connection. The tripod can be expanded or stored at the connection point with the fixed bracket 1.
[0021] The quick-connect connector 4 comprises a male quick-connect connector and a female quick-connect connector. The male quick-connect connector is located at one end of the metal hose 3, while the female quick-connect connector is located on the hydrogen system pipeline. The male quick-connect connector is designed to connect to the female quick-connect connector on the vehicle. It is simple and quick to disassemble and does not require rotation. The quick-connect connector is connected to the metal hose. Due to its high flexibility, it can be adjusted to different vehicle positions and different discharge angles. By adjusting the length of the horizontal pipeline, the height of the entire discharge system can be adjusted.
[0022] There are two pipeline fixing clamps 2 , which are located in the upper half of the fixing bracket 1 .
[0023] The working process of this utility model is as follows:
[0024] Unfold the tripod of the fixed support 1 and position the mobile hydrogen release device in the appropriate location. Connect the quick-connect male connector on the metal hose 3 to the quick-connect female connector on the hydrogen system pipeline and begin the release process. The check valve 5 ensures the flow of hydrogen and is only used during discharge to prevent excessive air accumulation in the pipeline. The vent valve 6 allows for direct discharge during evacuation, saving time.
