Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell structure, specifically a hydrogen-oxygen electrolytic cell structure. Background Technology

[0002] Hydrogen-oxygen electrolyzers primarily produce hydrogen and oxygen. During the electrolysis of water, water molecules undergo electrochemical reactions at the electrodes of the electrolyzer. When direct current passes through the electrolyzer, at the cathode, water molecules gain electrons and are reduced, reacting to produce hydrogen. At the anode, water molecules lose electrons and are oxidized, reacting to produce oxygen.

[0003] According to Chinese Patent No. CN222294214U, a hydrogen-oxygen electrolyzer structure is disclosed. In use, the pull rod is first held and rotated clockwise, causing the circular shaft and limiting plate to rotate 90 degrees. Next, the oxygen tube is installed at the top of the hydrogen-oxygen generator. Then, the limiting plate is pulled upwards and rotated counterclockwise 90 degrees, positioning the limiting plate at the top of the oxygen tube. Under the action of a first spring, the limiting plate will limit and press the oxygen tube. When the oxygen tube needs to be replaced or disassembled, the limiting plate is pulled upwards and rotated clockwise 90 degrees to disassemble the oxygen tube, thus enabling rapid disassembly and fixation of the oxygen tube.

[0004] Regarding the aforementioned patent content, the detachable oxygen tube facilitates its removal. However, while a sealing ring is provided at the connection between the oxygen tube and the electrolytic cell to improve the seal, the sealing ring may age or be damaged after prolonged use. This reduces the sealing effect, potentially causing oxygen to leak from the connection. Furthermore, it is difficult for staff to detect oxygen leaks in a timely manner, thus affecting the efficiency of oxygen discharge through the oxygen tube and reducing the effectiveness of the electrolytic cell. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a hydrogen-oxygen electrolyzer structure to solve the technical problem that it is difficult for staff to detect oxygen leakage in a timely manner when it occurs at the connection between the oxygen pipe and the electrolyzer.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydrogen-oxygen electrolyzer structure, comprising an electrolyzer body, an oxygen pipe, and a hydrogen pipe. A first fixed cover and a second fixed cover are installed on the top of the electrolyzer body. An electrochemical oxygen sensor is installed inside the first fixed cover, and a hydrogen sensor is installed inside the second fixed cover. Gaskets are installed on the outer walls of both the oxygen and hydrogen pipes. A slot is formed on one side of each gasket, and a retaining plate is inserted into the slot. A fixed frame is installed at the middle of the top of the electrolyzer body. A worm gear is connected to the inside of the fixed frame via a bearing, and a rotating shaft is also connected to the inside of the fixed frame via a bearing. Threaded holes are formed at both ends of the rotating shaft. A threaded rod penetrating the fixed frame is threaded into the inside of each threaded hole, and a worm wheel is installed on the outer wall of the threaded rod. Alarms are installed on both sides of the top of the electrolyzer body.

[0007] By adopting the above technical solution, when the worm gear rotates, it will drive the shaft to rotate, and the rotation of the shaft will drive the threaded hole to rotate, thereby causing the two threaded rods to move simultaneously, and then driving the clamping plate to move.

[0008] Furthermore, two mounting holes are respectively opened on the top of the electrolytic cell body, one of which is used to insert a hydrogen pipe and the other is used to insert an oxygen pipe.

[0009] By adopting the above technical solution, the installation hole is designed to facilitate the insertion of hydrogen and oxygen pipes and to connect the hydrogen and oxygen pipes to the main body of the electrolytic cell.

[0010] Furthermore, an anode is installed on one side of the interior of the electrolytic cell body, a cathode is installed on the other side of the interior of the electrolytic cell body, a diaphragm is installed in the middle of the interior of the electrolytic cell body, and liquid inlet pipes are connected to the upper sides of both sides of the electrolytic cell body.

[0011] By adopting the above technical solution, the design of the inlet pipe facilitates the entry of electrolyte into the interior of the electrolytic cell.

[0012] Furthermore, a first sealing ring is installed on the lower outer wall of both the oxygen tube and the hydrogen tube, with the outer wall of the first sealing ring fitting against the inner wall of the mounting hole. A second sealing ring is installed between the second fixing cover and the hydrogen tube, and between the first fixing cover and the oxygen tube.

[0013] By adopting the above technical solution, the setting of the first sealing ring can improve the sealing performance between the oxygen pipe and the hydrogen pipe and the main body of the electrolytic cell.

[0014] Furthermore, the inner walls of the two second sealing rings are respectively attached to the outer walls of the hydrogen pipe and the oxygen pipe, and an exhaust pipe is connected to one side of both the first and second fixed covers, and a valve is installed on the exhaust pipe.

[0015] By adopting the above technical solution, oxygen can be discharged through an oxygen pipe, while hydrogen can be discharged through a hydrogen pipe.

[0016] Furthermore, one end of the threaded rod is fixedly connected to the clamping plate, and the threads of the two threaded holes are in opposite directions.

[0017] By adopting the above technical solution, when the threaded rod moves, it will drive the clamping plate to move. After the clamping plate moves into the groove, it can clamp and limit the position of the washer ring.

[0018] Furthermore, a guide rod is installed at the top of the threaded rod, extending into the interior of the fixed frame.

[0019] By adopting the above technical solution, the guide rod can guide the threaded rod, prevent the threaded rod from rotating, and make the threaded rod only able to move laterally.

[0020] Furthermore, a control panel is installed on the outer surface of the electrolytic cell body, and the control panel is electrically connected to the electrochemical oxygen sensor, hydrogen sensor, alarm, cathode and anode respectively.

[0021] By adopting the above technical solution, the electrochemical oxygen sensor, hydrogen sensor, alarm, cathode, and anode can be started or stopped via the control panel.

[0022] Furthermore, both the first and second fixing covers have positioning grooves on their top sides, and positioning blocks are inserted into the positioning grooves. The top of the positioning blocks is fixedly connected to the bottom of the gasket ring.

[0023] By adopting the above technical solution, when installing oxygen and hydrogen pipes, workers can insert positioning blocks into the positioning grooves to position the oxygen and hydrogen pipes.

[0024] Furthermore, the worm gear meshes with the worm, and a handle is installed at the top of the worm.

[0025] By adopting the above technical solution, it is convenient for workers to rotate the worm gear by turning the handle, and the rotation of the worm gear will drive the worm wheel to rotate.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model is equipped with a first fixed cover, a second fixed cover, a hydrogen sensor, an electrochemical oxygen sensor, and an alarm. When oxygen leaks at the connection between the oxygen pipe and the main body of the electrolytic cell, the leaked oxygen will enter the first fixed cover, where the electrochemical oxygen sensor will detect the oxygen. Conversely, if hydrogen leaks at the connection between the hydrogen pipe and the main body of the electrolytic cell, hydrogen will enter the second fixed cover, where the hydrogen sensor will detect the hydrogen. This causes either the electrochemical oxygen sensor or the hydrogen sensor to transmit a signal to the control panel. Upon receiving the signal, the control panel will activate the alarm, which will sound an alarm to alert nearby personnel that there is a hydrogen or oxygen leak. This allows personnel to detect the leak promptly, preventing it from continuing undetected and improving the efficiency of the electrolytic cell.

[0028] 2. This utility model improves the sealing between the oxygen pipe and the first fixing cover and the hydrogen pipe and the second fixing cover by providing a second sealing ring, preventing oxygen from escaping from the gap between the first fixing cover and the oxygen pipe 9, and also preventing oxygen from escaping from the gap between the second fixing cover and the hydrogen pipe. It also provides a gasket, a positioning block and a positioning groove so that when installing the oxygen pipe or hydrogen pipe, the positioning block can be inserted into the positioning groove, thereby positioning the oxygen pipe or hydrogen pipe.

[0029] 3. This utility model, by comprising a worm gear, a worm wheel, a rotating shaft, a threaded hole, a threaded rod, a slot, and a locking plate, allows the operator to rotate the worm gear after the hydrogen or oxygen tube is inserted into the electrolytic cell and the slot aligns with the locking plate. The rotation of the worm gear drives the worm wheel to rotate, which in turn drives the rotating shaft. The rotating shaft then drives the threaded hole to rotate, causing the threaded rod to move. The threaded rod then moves the locking plate, causing it to engage with the slot and secure the gasket, thus limiting the movement of the oxygen or hydrogen tube. This completes the installation of the hydrogen or oxygen tube while improving its stability and preventing movement. A guide rod is also included to guide the threaded rod, further enhancing its stability during movement. Attached Figure Description

Detailed Implementation

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of this utility model will be described below based on its overall structure.

[0040] Example 1:

[0041] A hydrogen-oxygen electrolyzer structure, such as Figures 1-7 As shown, the electrolytic cell body 1 includes an oxygen pipe 9 and a hydrogen pipe 8. The top of the electrolytic cell body 1 is also equipped with a first fixing cover 11 and a second fixing cover 16. An electrochemical oxygen sensor 12 is installed inside the first fixing cover 11, and a hydrogen sensor 15 is installed inside the second fixing cover 16. The hydrogen sensor 15 is a PDM300 type hydrogen sensor. Gaskets 19 are installed on the outer walls of both the oxygen pipe 9 and the hydrogen pipe 8. A slot 20 is opened on one side of the gasket 19, and a retaining plate 28 is inserted into the slot 20. A fixing frame 23 is installed at the middle position of the top of the electrolytic cell body 1. A worm gear 24 is connected to the inside of the fixing frame 23 through a bearing. A rotating shaft 26 is also connected to the inside of the fixing frame 23 through a bearing. Threaded holes 27 are opened at both ends of the rotating shaft 26. A threaded rod 21 that passes through the fixing frame 23 is threadedly connected inside the threaded holes 27, and a worm wheel 25 is installed on the outer wall of the threaded rod 21.

[0042] Specifically, alarms 6 are installed on both sides of the top of the electrolytic cell body 1. When the worm gear 25 rotates, it drives the shaft 26 to rotate. The rotation of the shaft 26 drives the threaded hole 27 to rotate, which in turn causes the two threaded rods 21 to move simultaneously, and then drives the clamping plate 28 to move. One side of the first fixed cover 11 and the second fixed cover 16 are connected to the exhaust pipe 13, and the exhaust pipe 13 is equipped with a valve 14. Oxygen can be discharged through the oxygen pipe 9, and hydrogen can be discharged through the hydrogen pipe 8. One end of the threaded rod 21 is fixedly connected to the clamping plate 28. The threads of the two threaded holes 27 are opposite. The clamping plate 28 is adapted to the clamping groove 20. When the threaded rod 21 moves, it drives the clamping plate 28 to move. After the clamping plate 28 moves into the clamping groove 20, it can clamp and limit the washer 19. The worm gear 25 meshes with the worm 24. A handle is installed at the top of the worm 24, which makes it convenient for the operator to rotate the worm 24 through the handle. The rotation of the worm 24 will drive the worm gear 25 to rotate.

[0043] See Figures 1-5 Two mounting holes 7 are respectively opened on the top of the electrolytic cell body 1. A hydrogen pipe 8 is inserted into one mounting hole 7 and an oxygen pipe 9 is inserted into the other mounting hole 7. The mounting holes 7 are set to facilitate the insertion of the hydrogen pipe 8 and oxygen pipe 9 and to connect the hydrogen pipe 8 and oxygen pipe 9 to the electrolytic cell body 1. Both the hydrogen pipe 8 and oxygen pipe 9 are detachably connected to the electrolytic cell body 1. An anode 5 is installed on one side of the inside of the electrolytic cell body 1, and a cathode 2 is installed on the other side of the inside of the electrolytic cell body 1. A diaphragm 3 is installed in the middle of the inside of the electrolytic cell body 1. Liquid inlet pipes 4 are connected to the upper sides of the electrolytic cell body 1. The liquid inlet pipes 4 are set to facilitate the electrolyte to enter the inside of the electrolytic cell body 1. A control panel 17 is installed on the upper surface of the outer surface of the electrolytic cell body 1. The control panel 17 is electrically connected to the electrochemical oxygen sensor 12, hydrogen sensor 15, alarm 6, cathode 2 and anode 5 respectively, so that the electrochemical oxygen sensor 12, hydrogen sensor 15, alarm 6, cathode 2 and anode 5 can be started or stopped through the control panel 17.

[0044] Example 2:

[0045] Based on the above embodiment 1, in order to improve the sealing between the oxygen pipe 9 and the first fixed cover 11 and the hydrogen pipe 8 and the second fixed cover 16, the following structure will be provided.

[0046] See Figures 2-5A first sealing ring 10 is installed on the lower outer wall of both the oxygen pipe 9 and the hydrogen pipe 8. The outer wall of the first sealing ring 10 fits against the inner wall of the mounting hole 7. The first sealing ring 10 can improve the sealing between the oxygen pipe 9 and the hydrogen pipe 8 and the electrolytic cell body 1. A second sealing ring 18 is installed between the second fixing cover 16 and the hydrogen pipe 8 and between the first fixing cover 11 and the oxygen pipe 9. The inner walls of the two second sealing rings 18 fit against the outer walls of the hydrogen pipe 8 and the oxygen pipe 9, respectively.

[0047] Example 3:

[0048] Based on the above embodiment 1, in order to improve the stability of the threaded rod 21 when it moves, it is necessary to guide the threaded rod 21, so the following structure will be set.

[0049] Specifically, a guide rod 22 is installed at the top of the threaded rod 21, which extends into the interior of the fixed frame 23. The guide rod 22 can guide the threaded rod 21, prevent the threaded rod 21 from rotating, and allow the threaded rod 21 to move only laterally.

[0050] Example 4:

[0051] Based on the above embodiment one, in order to facilitate the installation of oxygen pipe 9 and hydrogen pipe 8, the following structure will be set up to position oxygen pipe 9 and hydrogen pipe 8.

[0052] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The first fixing cover 11 and the second fixing cover 16 are both provided with positioning grooves 30 on one side of the top, and positioning blocks 29 are inserted into the positioning grooves 30. The top of the positioning block 29 is fixedly connected to the bottom of the gasket 19. When installing the oxygen tube 9 and the hydrogen tube 8, the operator can insert the positioning block 29 into the positioning groove 30 to position the oxygen tube 9 and the hydrogen tube 8, and make the slot 20 aligned with the card plate 28, so that the card plate 28 can be inserted into the slot 20 later.

[0053] The working principle of this utility model is as follows: First, during use, the operator installs the hydrogen pipe 8 and oxygen pipe 9 onto the main body 1 of the electrolytic cell. The installation process involves inserting the hydrogen pipe 8 and oxygen pipe 9 into the two mounting holes 7 respectively, so that the gasket 19 on the oxygen pipe 9 is in contact with the top of the first fixing cover 11, and at the same time, the gasket 19 on the hydrogen pipe 8 is in contact with the top of the second fixing cover 16, and the positioning block 29 at the bottom of the gasket 19 is inserted into the positioning groove 30. At this time, the retaining plate 28 is aligned with the retaining groove 20. Then... The operator can rotate the worm gear 24. When the worm gear 24 rotates, it will drive the worm wheel 25 to rotate, which in turn drives the rotating shaft 26 to rotate. The rotating shaft 26 will drive the threaded hole 27 to rotate, which will cause the threaded rod 21 to move. The threaded rod 21 will drive the clamping plate 28 to move, so that the clamping plate 28 can be inserted into the groove 20, which can then clamp and limit the washer 19. In this way, the installation of the hydrogen pipe 8 and the oxygen pipe 9 can be completed. At the same time, the first sealing ring 10 below the outer wall of the hydrogen pipe 8 and the oxygen pipe 9 will fit against the inner wall of the installation hole 7.

[0054] After installation, the power can be connected, and the electrolyte can enter the electrolytic cell body 1 through the inlet pipe 4. Then, the electrolytic cell is started to electrolyze the electrolyte. During the electrolysis process, the oxygen produced is discharged through the oxygen pipe 9, and the hydrogen is discharged through the hydrogen pipe 8. When oxygen leaks at the connection between the oxygen pipe 9 and the electrolytic cell body 1, the leaked oxygen will enter the first fixed cover 11. At this time, the electrochemical oxygen sensor 12 will detect the oxygen. If hydrogen leaks at the connection between the hydrogen pipe 8 and the electrolytic cell body 1, the hydrogen will enter the second fixed cover 16. At this time, the hydrogen sensor 15 will detect the hydrogen. At this time, the electrochemical oxygen sensor 12 or the hydrogen sensor 15 will transmit a signal to the control panel 17. After receiving the signal, the control panel 17 will activate the alarm 6, which will sound an alarm to alert the surrounding staff that there is a hydrogen or oxygen leak, so that the staff can discover it in time.
