[0023] The technical solutions in the application will be described in detail below with reference to the drawings. In the description of the embodiments of the application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B: the "and / or" in the text only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone. In addition, in the description of the embodiments of the application, "multiple" means two or more than two.

[0024] Hereinafter, the terms "first" and "second" are only used for description purposes, and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more features.

[0025] In the electrolytic cell, the electrolytic cell main pipeline gas source is controlled by a ball valve, and the ball valve is closed during daily production and maintenance, but the phenomenon of forgetting to open the ball valve often occurs, which affects the safe use of the electrolytic cell.

[0026] Therefore, the valve closing alarm device for the electrolytic cell provided in the embodiments of the present application can avoid single-cell gas stop caused by forgetting to open the valve to a certain extent, and effectively improves the use safety of the electrolytic cell.

[0027] The embodiments of the present application will be described in detail below with reference to the drawings and specific embodiments.

[0028] Please refer to Figure 1 , Figure 1 The structure diagram of the valve closing alarm device for the electrolytic cell provided in the embodiments of the present application is shown in the figure. The valve closing alarm device for the electrolytic cell comprises an electrolytic cell, a ball valve 1, an induction switch 2, a gas control cabinet 3, a power supply 4 and an alarm lamp 5, and the electrolytic cell has a main pipeline 6; the ball valve 1 is installed on the main pipeline 6 and has a handle 11; the induction switch 2 has a driving rod 21, and when the ball valve 1 is closed, the handle 11 contacts the driving rod 21 to close the induction switch 2; the gas control cabinet 3 is electrically connected with the induction switch 2, and the main pipeline 6 is in communication with the gas control cabinet 3; the power supply 4 and the alarm lamp 5 are both electrically connected with the gas control cabinet 3.

[0029] In this way, when the ball valve 1 is closed, the handle 11 contacts the driving rod 21 to close the induction switch 2, and then the circuit between the induction switch 2 and the gas control cabinet 3 is conducted, at this time, the alarm lamp 5 flashes and emits an alarm sound, so as to remind the staff to open the ball valve 1, so that the electrolytic cell can be used normally.

[0030] It should be noted that the power supply 4 is used to supply power to the gas control cabinet 3, and can also supply power to the alarm lamp 5. In this regard, the specific power supply mode of the power supply 4 is not limited.

[0031] Please refer to Figure 2 , Figure 2 The structure diagram of the ball valve in the valve closing alarm device for the electrolytic cell provided in the embodiments of the present application is shown in the figure, Figure 3 is Figure 2 the enlarged diagram of the local structure at A in the figure. In some specific embodiments, the handle 11 comprises a main body part 111 and a matching part 112 formed on the main body part 111; the matching part 112 abuts against the driving rod 21, and the shape of the matching part 112 is adapted to the contour shape of the induction switch 2. In this way, by providing the matching part 112, the handle 11 can effectively abut against the driving rod 21 to effectively close the induction switch 2.

[0032] In order to avoid abrasion caused by hard collision when the matching portion 112 abuts against the driving rod 21, in some embodiments, a flexible pad 7 is arranged on the matching portion 112 and abuts against the driving rod 21. In this way, the flexible pad 7 abuts against the driving rod 21, so that the hard collision between the matching portion 112 and the driving rod 21 can be avoided to some extent, so as to avoid abrasion between the handle 11 and the driving rod 21 to some extent.

[0033] In actual use, the handle 11 can sense the induction switch 2.

[0034] It can be understood that, in the process of closing the ball valve 1, the handle 11 needs to be rotated from the vertical state to the horizontal state, that is, the handle 11 has a certain kinetic energy during rotation, and when abutting against the driving rod 21, a certain impact will be generated. In order to avoid that the impact is too large to have a substantial impact on the structure of the handle 11 or the induction switch 2, in some optional embodiments, the flexible pad 7 is elastic. In this way, when the handle 11 collides with the driving rod 21, a certain buffering effect can be achieved to avoid having a substantial impact on the structure of the handle 11 or the induction switch 2.

[0035] The flexible pad 7 can be a rubber pad. Here, the material of the flexible pad 7 is not limited.

[0036] Since the entire matching portion 112 will abut against the driving rod 21, in order to avoid hard collision between the local area on the matching portion 112 and the driving rod 21 to some extent, in some embodiments, the flexible pad 7 covers the matching portion 112. In this way, when the matching portion 112 contacts the driving rod 21, it is flexible contact, so as to avoid having an impact on the structure of the handle 11 and the induction switch 2 to some extent.

[0037] In some embodiments, in order to improve the connection reliability between the flexible pad 7 and the handle 11, the flexible pad 7 can extend to the main body portion 111. In this way, the contact area between the flexible pad 7 and the handle 11 can be increased, so as to improve the connection reliability between the flexible pad 7 and the handle 11.

[0038] It is not difficult to understand that, in use, the flexible pad 7 will also be abraded, therefore, in order to be able to replace the flexible pad 7 and ensure the connection reliability between the flexible pad 7 and the matching portion 112, the flexible pad 7 is bonded to the matching portion 112. In this way, when the flexible pad 7 is abraded, the flexible pad 7 can be torn off for replacement, and the bonding connection mode is relatively firm, so as to avoid the flexible pad 7 from falling off the matching portion 112 to some extent.

[0039] When the flexible pad 7 is bonded to the fitting portion 112, the flexible pad 7 can be bonded to the fitting portion 112 by an adhesive, or the flexible pad 7 can be provided with the adhesive. The adhesive can be an adhesive or the like, and the type of the adhesive is not limited herein.

[0040] In order to improve the bonding reliability of the flexible pad 7, in the present embodiment, the adhesive covers the surface of the flexible pad 7 in contact with the fitting portion 112. In this way, the adhesive is present at each position of the flexible pad 7 in contact with the fitting portion 112, and the connection reliability between the flexible pad 7 and the fitting portion 112 can be improved.
