[0002] In existing technologies, such as the Chinese patent CN218381453U entitled "A Hydrogen Leakage Alarm Device for a Hydrogen Storage Tank," a hydrogen storage tank is included. A tank base is located at the bottom of the tank, and a connecting seat is located on one side of the tank base. A quick-connect assembly is located at the end of the connecting seat near the hydrogen filling port of the storage tank. A connecting rod is located at the end of the quick-connect assembly away from the connecting seat, and the end of the connecting rod away from the quick-connect assembly extends to the side of the hydrogen filling port of the storage tank and is connected to a hydrogen detection mechanism. This invention offers high stability in use, is suitable for detecting hydrogen concentration in hydrogen storage tanks, and can promptly detect hydrogen leaks, thus triggering an alarm.
[0003] The mounting plate in this device is fixed by several bolts, which is cumbersome to operate and difficult to remove. In addition, the quick-connect assembly has an opening in the cylinder, which limits the material of the quick-connect assembly. It is not convenient to use harder materials such as aluminum alloy, and harder materials would make the connecting rod more secure. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the use of multiple bolts for fixing, which is cumbersome and difficult to disassemble, and the limited material availability of quick-connect components. This invention provides a gas leak detection device for hydrogen storage tanks.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gas leak detection device for a hydrogen storage tank, comprising a storage tank, a support base fixedly connected to the bottom of the storage tank, a clamping plate engaged with the surface of the support base, a support plate fixedly connected to one side of the clamping plate, and a connecting assembly provided on the other side of the clamping plate. The connecting assembly includes a mounting block, a slot provided on one side of the mounting block, a fixing plate provided on the top of the slot, and a fixed connection on one side of the fixing plate.
[0006] The mounting block is equipped with a push plate, and a movable slot is provided on the outer surface of the mounting block. A connecting rod is provided on one side of the mounting block, and a detection mechanism is fixedly connected to the top of the connecting rod. A threaded cap is provided on the outer surface of the support plate, and a support hoop is fixedly connected to one side of the threaded cap. A threaded rod is slidably connected to the outer surface of the support plate through a through hole. A connecting frame is fixedly connected to the outer surface of the support plate, and a plug is fixedly connected to the top of the connecting rod. A locking hole is provided on the outer surface of the plug.
[0007] In a preferred embodiment, a top plate is attached to one side of the push plate, and a spring is fixedly connected to the outer surface of the top plate.
[0008] In a preferred embodiment, the two sides of the top plate and the inner wall of the movable slot are slidably connected.
[0009] In a preferred embodiment, one side of the mounting block is fixedly connected to the outer surface of the clamping plate.
[0010] In a preferred embodiment, the inner wall of the support hoop is rotatably connected to the outer surface of the connecting frame via a bearing.
[0011] In a preferred embodiment, the inner wall of the slot and the outer surface of the plug are engaged, and the two sides of the push plate are slidably connected to the inner wall of the movable slot.
[0012] In a preferred embodiment, the top of the connecting rod is fixedly connected to one side of the mounting block by a plug.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] This invention features a support plate that allows for the placement of a threaded rod on one side. The rotation of the threaded rod causes it to press tightly against the inner wall of the support base, enabling the clamping plate to be securely engaged with the support base surface. A support hoop and connecting frame support the rotation of the threaded cap on one side of the support plate, thereby driving the threaded rod to move back and forth. This eliminates the need for multiple bolts used in previous technologies, reducing the complexity of the installation process. Furthermore, the connecting assembly makes the connection between the connecting rod and the clamping plate more convenient and ensures a more secure fixation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0023] As shown in Figures 1-5, this utility model provides a technical solution: a gas leak detection device for a hydrogen storage tank, including a storage tank 1, a support base 2 fixedly connected to the bottom of the storage tank 1, a clamping plate 3 engaged with the surface of the support base 2, a support plate 4 fixedly connected to one side of the clamping plate 3, and a connecting component 5 provided on the other side of the clamping plate 3. The connecting component 5 includes a mounting block 51, one side of the mounting block 51 fixedly connected to the outer surface of the clamping plate 3, and a slot 52 formed on one side of the mounting block 51. The inner wall of the slot 52 and...
[0024] The outer surface of the plug 12 is engaged. A fixing plate 53 is provided on the top of the slot 52. A push plate 54 is fixedly connected to one side of the fixing plate 53. The two sides of the push plate 54 are slidably connected to the inner wall of the moving slot 57. The outer surface of the mounting block 51 is provided with a moving slot 57. A connecting rod 6 is provided on one side of the mounting block 51. The top of the connecting rod 6 is fixedly connected to one side of the mounting block 51 through the plug 12. A detection mechanism 7 is fixedly connected to the top of the connecting rod 6. A threaded cap 8 is provided on the outer surface of the support plate 4. A support hoop 9 is fixedly connected to one side of the threaded cap 8. The inner wall of the support hoop 9 is rotatably connected to the outer surface of the connecting frame 11 through a bearing. A threaded rod 10 is slidably connected to the outer surface of the support plate 4 through a through hole. A connecting frame 11 is fixedly connected to the outer surface of the support plate 4. The top of the connecting rod 6 is fixedly connected to the plug 12. The outer surface of the plug 12 is provided with an engaging hole 13.
[0025] In this embodiment, by setting a support plate 4, a threaded rod 10 can be installed on one side. The rotation of the threaded rod 10 allows it to fit tightly against the inner wall of the support base 2, enabling the clamping plate 3 to be tightly engaged with the surface of the support base 2. A support hoop 9 and a connecting frame 11 are provided to support the rotation of the threaded cap 8 on one side of the support plate 4, thereby driving the threaded rod 10 to move back and forth. This eliminates the need for multiple bolts in the original technology, reducing the complexity of the installation process. The connection component 5 makes the connection between the connecting rod 6 and the clamping plate 3 more convenient and secure. During installation, the push plate 54 is pulled to move the fixing plate 53 away from the slot 52. A simple connection is then established by the engagement of the insert 12 and the slot 52. The fixing plate 53 is then rotated into the engagement hole 13 to secure the insert 12 and the slot 52. Additionally, a moving groove is provided at the bottom of the moving slot 57 to facilitate the movement of the fixing plate 53 and the push plate 54. Moving backward, the detection mechanism 7 is the structure of the original technology, which will not be explained in detail here. Example
[0026] like Figure 4 As shown, a top plate 55 is attached to one side of the push plate 54, and a spring 56 is fixedly connected to the outer surface of the top plate 55. The two sides of the top plate 55 are slidably connected to the inner wall of the moving slot 57.
[0027] In this embodiment, a top plate 55 and two springs 56 are provided. The initial state of the springs 56 is to push the top plate 55 against the outer surface of the push plate 54, and to push the fixing plate 53 against the slot 52.
[0028] Therefore, when the fixing plate 53 is used to fix the insertion rod 12 and the slot 52, the top plate 55 and the spring 56 can prevent the push plate 54 and the fixing plate 53 from becoming loose. The spring 56 is provided with a telescopic groove, which can accommodate the top plate 55 after the spring 56 is compressed.
[0029] Working principle:
[0030] As shown in Figures 1-5, during installation, the support hoop 9 and connecting frame 11 allow the support thread cap 8 to rotate on one side of the support plate 4, causing the top of the threaded rod 10 to press tightly against the inner wall of the support base 2, and the clamping plate 3 to snap tightly onto the surface of the support base 2. Then, to fix the connecting rod 6, the push plate 54 is pulled, causing the fixing plate 53 to move away from the slot 52. The spring 56 is compressed in the telescopic groove, and the top plate 55 is housed in the telescopic groove. A simple connection is then established through the engagement between the insert 12 and the slot 52. The fixing plate 53 is then rotated into the engagement hole 13 to achieve fixation between the insert 12 and the slot 52. Simultaneously, the top plate 55 is pushed against the outer surface of the push plate 54 by the rebound of the spring 56.
[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
