Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen production electrolytic cells, and specifically relates to an electrolytic hydrogen production device with a water leakage alarm. Background Art

[0002] The alkaline electrolytic cell is the main device for industrial hydrogen production. When it works, direct current is introduced. That is, when direct current passes through the electrolytic cell, an oxidation reaction occurs at the anode and solution interface, and a reduction reaction occurs at the cathode and solution interface to produce the required products.

[0003] The tank body of the alkaline electrolytic cell includes a plurality of gaskets and electrode plates. Adjacent layers are sealed by gaskets. However, the gaskets will age after long-term use. Therefore, water leakage may occur after the tank body is used for a long time. If water leakage occurs, hydrogen leakage and other situations may occur, leading to dangerous situations. For this reason, we propose an electrolytic hydrogen production device with a water leakage alarm. Content of the Utility Model

[0004] Aiming at the deficiency that the existing hydrogen production electrolytic cell cannot be detected in time after water leakage, the utility model provides an electrolytic hydrogen production device with a water leakage alarm, which has the advantages of gathering the leaked water, lifting the floating liquid level switch to conduct when the water gathers to a certain height, and making the alarm give an alarm, thus solving the problems put forward in the above background art.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0006] Design an electrolytic hydrogen production device with a water leakage alarm, including an electrolytic cell. The tank body in the middle of the electrolytic cell is placed in a cylindrical protective shell, and there is a certain distance between the protective shell and the tank body;

[0007] Both ends of the protective shell are connected to the supports at both ends of the electrolytic cell. A floating liquid level switch is installed at the bottom of the protective shell. The floating liquid level switch is connected to the alarm. When the tank body leaks water, the water will gather at the bottom of the protective shell. The floating liquid level switch is turned on as the liquid level rises, causing the alarm to give an alarm.

[0008] Preferably, the protective shell includes an upper protective cover and a lower protective cover, and the tank body is located between the upper protective cover and the lower protective cover.

[0009] Preferably, second connecting flanges are provided on the sides of the upper protective cover and the lower protective cover that are close to each other. First connecting flanges are provided at both ends of the upper protective cover and the lower protective cover. The first connecting flanges are detachably connected to the supports, and the second connecting flanges are detachably connected to each other.

[0010] Preferably, air flow channels are provided at both ends of the upper protective cover, and a fan is installed in each air flow channel. One fan blows air into the protective shell, and the other fan exhausts air towards the outside of the protective shell.

[0011] Preferably, a plurality of wire grooves for wire threading are provided on the side surface of the lower protective cover.

[0012] Preferably, protective nets are provided at the top of the air flow channels.

[0013] Preferably, the bottom of the lower protective cover is an inclined surface that slopes downward, and at the bottom of the inclined surface is a horizontal water collecting area, and the floating liquid level switch is arranged at the horizontal water collecting area.

Therefore, when the tank body leaks, it can be quickly detected. Description of the Drawings

Detailed Embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: an electrolytic hydrogen production device with leakage alarm, including an electrolytic cell, and the tank body 7 in the middle of the electrolytic cell is placed in a cylindrical protective housing. As Figure 1As shown in the figure, the protective housing includes an upper protective cover 1 and a lower protective cover 3. The groove body 7 is located between the upper protective cover 1 and the lower protective cover 3. Both ends of the protective housing are respectively connected to the supports 4 at both ends of the electrolytic cell. That is, connection mechanisms for connecting with the groove body are provided at both ends of the upper protective cover 1 and the lower protective cover 3. The specific structure of the connection mechanism includes a second connection flange 5 on the side of the upper protective cover 1 and the lower protective cover 3 that are close to each other, and first connection flanges 2 are provided at both ends of the upper protective cover 1 and the lower protective cover 3. The first connection flange 2 is detachably connected to the support 4, and the second connection flanges 5 are detachably connected to each other. That is, both between the first connection flange 2 and the support 4 and between the second connection flanges 5 are fixed by bolts.

[0022] There is a certain distance between the upper protective cover 1, the lower protective cover 3 and the groove body 7 respectively, so that the groove body and the protective cover do not contact. When the groove body leaks water after long-term use, the water will gather inside the protective housing and flow downward along the inside of the protective housing, and finally will gather in the lower protective cover 3.

[0023] A floating liquid level switch 10 is installed at the bottom of the protective housing. The floating liquid level switch 10 is connected to an alarm 11. The alarm 11 can be set on the side of the support 4 or on the side of the protective housing. The specific process is that when the groove body 7 leaks water, it will gather at the bottom of the protective housing (that is, inside the lower protective cover 3). When the water level reaches the preset height, the floating liquid level switch 10 is turned on as the liquid level rises to make the alarm 11 give an alarm. The alarm 11 can be an audible and visual alarm.

[0024] Furthermore, in order to enable the groove body to dissipate heat better, as Figure 1 shown, air flow channels 6 are respectively provided at both ends of the upper protective cover 1. A fan is installed in each air flow channel 6, or each air flow channel 6 is respectively connected to a fan through a pipe. One fan blows air into the protective housing, and the other fan exhausts air towards the outside of the protective housing. After the fan blows air into the protective housing, the flowing air flows from one end of the groove body to the other end, so that the air flows rapidly around the groove body, and finally the air is discharged from the other exhaust fan. This method can make the outside cold air flow rapidly around the groove body, and can quickly disperse the heat on the surface of the groove body. A protective net is provided at the top of the air flow channel 6 or at the end of the pipe.

[0025] Furthermore, a plurality of wire grooves 12 for wire threading are provided on the side of the lower protective cover 3. Because in the actual operation process, the electrode plates in the groove body need to be connected to an external power supply through wires, and the wires can pass through the wire grooves 12.

[0026] Furthermore, as Figure 1 and Figure 3As shown in the figure, the bottom of the lower protective cover 3 is an inclined surface 8 that slopes downward. At the bottom of the inclined surface 8 is a horizontal water collecting area 9. The floating liquid level switch 10 is arranged at the horizontal water collecting area 9. The arranged inclined surface 8 can make the water flowing in the protective shell quickly flow into the horizontal water collecting area 9, allowing the water to quickly gather;

[0027] The floating liquid level switch 10 is installed on the top of the bracket 13. The bracket is arranged on the horizontal water collecting area 9. By arranging the floating liquid level switch 10 at a high position in the horizontal water collecting area 9, the floating ball of the floating liquid level switch 10 is placed on the horizontal water collecting area 9. When the floating ball contacts the water, it can be lifted.

[0028] In summary, the water flowing out of the tank will flow out from the gap. Because there is a certain water pressure in the tank, when there is a gap in the tank, the water will shoot out. The water that shoots out will be blocked by the protective cover. If the water seeps out, it will also be blocked by the protective cover. Therefore, the water will flow through the inclined surface 8 into the horizontal water collecting area 9, allowing the water to quickly gather and thus lift the floating liquid level switch 10, enabling the alarm to be turned on for alarm.
