Description

Technical Field

[0002] Water electrolysis is a chemical reaction process in which water molecules are decomposed into hydrogen and oxygen under the action of electric current. In this process, electric current is necessary, which provides the electrical energy required for electrolysis, and cables are often connected to electrodes to provide electrical energy for the electrodes. Since the electrolyte in this reaction is water, the cable needs to have corrosion resistance and high temperature resistance when providing electrical energy to the electrodes to cope with water corrosion and the heat generated during electrolysis. Good corrosion resistance enables the cable to be used in the deep sea.

[0003] The prior art still has the following disadvantages when connecting the cable to the electrode:

[0004] 1. When the cable is connected to the electrode, the wire core is often connected to the electrode by bolts and squeezed contact pieces. The installation requires corresponding tools, which is cumbersome.

[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0047] Example 1

[0048] Reference Figure 1-Figure 5 , cable, which is used in cable-related fields, the cable for electrolyzing water to obtain hydrogen is composed of the following layers from the outside to the inside:

[0049] Corrosion-resistant layer 1: As the outermost layer, it is made of corrosion-resistant materials, such as polyvinyl chloride or fluoroplastics, to resist corrosion factors in the external environment.

[0050] Wire mesh layer 2: Enhances the mechanical strength of the cable and protects the internal structure from external damage.

[0051] High temperature resistant layer 3: Made of high temperature resistant materials, such as polyimide, to ensure the stability of the cable in high temperature environments.

[0052] The first insulating layer 4 is an electrical insulating layer that prevents current leakage and is made of insulating material with high dielectric strength.

[0053] Inner sleeve 5: provides internal support and protection, usually made of high-strength plastic or metal.

[0054] Second insulating layer 6: further enhances the insulating effect and protects the cable core 7 from the external environment.

[0055] Cable core 7: It is composed of multiple copper wire cores and serves as the main channel for current transmission. One end of the cable core extends into the connector sleeve 8 and is fixedly connected to the connecting contact 10.

[0056] Reference Figure 1 and Figure 2 The connector sleeve 8 is fixedly mounted on the outer wall of the cable, and a sliding space and corresponding structure are designed inside to accommodate the extrusion sheet 16 and other connection components. The electrode 9 is fixed at one end of the cable, and a fixed contact sheet 11 is provided on the top thereof. The fixed contact sheet 11 extends into the connector sleeve 8 and is used to be electrically connected to the connection contact sheet 10. The connection contact sheet 10 is arranged at the bottom end of the cable, and cooperates with the fixed contact sheet 11, and a stable connection is achieved through the extrusion of the extrusion sheet 16.

[0057] Reference Figure 2-Figure 4 There are two circular holes 13 in each of the fixed contact piece 11 and the connecting contact piece 10, which are used to cooperate with the insertion rod 17 on the extrusion piece 16 to achieve limiting and fixing. Extrusion piece 16: Slidingly connected in the connector sleeve 8, two insertion rods 17 are fixed on one side. When the extrusion piece 16 moves, the insertion rod 17 is inserted into the circular hole 13 to complete the extrusion and fixing of the connecting contact piece 10.

[0058] Reference Figure 2-Figure 4 The extrusion structure includes a first slide bar 18, which is fixed on the side of the extrusion sheet 16 away from the connecting contact sheet 10, and one end of which slides and extends into the circular groove 20 on the side of the joint sleeve 8. A reset spring 19 is sleeved on the outer wall of the first slide bar 18, one end of which is fixedly connected to the extrusion sheet 16, and the other end of which is fixedly connected to the inner wall of one side of the joint sleeve 8, and is used to automatically reset the extrusion sheet 16 when not subjected to external force. A connector 21 is rotatably connected to one end of the first slide bar 18 and is located in the circular groove 20, and can release or restore the blocking relationship with the limit block 22 by rotation. The limit block 22 is fixed to the top and bottom inner walls of the circular groove 20, and is used to block the connector 21 and limit its rotation range. A paddle 23 is fixed to one side of the connector 21, and is used to manually pull the connector 21 to rotate, thereby changing its relative position with the limit block 22.

[0059] Specifically, when the cable needs to be connected, the connector 21 is first rotated by the paddle 23 to release the blocking relationship between the connector 21 and the stop block 22. Then, the first slide bar 18 and the extrusion sheet 16 are pulled outward, and the reset spring 19 is stretched. After the connecting contact sheet 10 is docked with the fixed contact sheet 11, the first slide bar 18 is released, and under the action of the reset spring 19, the extrusion sheet 16 moves inward, and the insertion rod 17 is inserted into the circular hole 13, completing the extrusion and fixation of the connecting contact sheet 10.

[0060] Through the above-mentioned specific implementation methods, the cable for obtaining hydrogen by electrolysis of water achieves stable and reliable electrical connection, and at the same time has good corrosion resistance, high temperature resistance and mechanical strength characteristics, meeting the high requirements in the process of hydrogen production by electrolysis of water.

[0061] The cable for obtaining hydrogen by electrolyzing water in this embodiment has a rectangular hole 12 in its connecting contact piece 10. The top inner wall and the bottom inner wall of the rectangular hole 12 are firmly fixed with fixing blocks 14, which are respectively located at the upper and lower ends of the rectangular hole 12 to play a supporting and positioning role.

[0062] Reference Figure 2-Figure 4 Two spring contacts 15 are installed inside the rectangular hole 12. The two spring contacts 15 are elastic, and one side of them is respectively connected to one end of the two fixing blocks 14 by welding or other reliable fixing methods. Therefore, the spring contacts 15 can freely expand and contract in the rectangular hole 12 under the constraint of the fixing blocks 14.

[0063] Specifically, when the cable is connected to an external device, the extrusion sheet 16 applies an inward extrusion force to the connecting contact sheet 10. At this time, the fixed contact sheet 11 and the extrusion sheet 16 act on the two spring contacts 15 at the same time, causing them to deform. Due to the elastic properties of the spring contacts 15, they can fit tightly between the fixed contact sheet 11 and the extrusion sheet 16, thereby greatly increasing the contact area and reducing the contact resistance. This design effectively improves the conductive stability between the connecting contact sheet 10 and the fixed contact sheet 11, ensuring the smoothness and safety of current transmission.

[0064] Reference Figure 5 The corrosion-resistant layer 1 is made of polyvinyl chloride (PVC) material. Polyvinyl chloride has excellent corrosion resistance and can effectively resist the erosion of various corrosive substances that may be produced during the electrolysis of water, thereby extending the service life of the cable.

[0065] Reference Figure 5 The high temperature resistant layer 3 is made of polyimide PI material. Polyimide is a high-performance thermoplastic resin with extremely high temperature resistance. It can maintain stable physical and chemical properties in high temperature environments, ensuring the safety of the cable in high temperature working environments.

[0066] Reference Figure 5 The first insulating layer 4 and the second insulating layer 6 of the cable are also made of polyvinyl chloride (PVC) material. This is because polyvinyl chloride not only has good insulation properties, but also can effectively isolate the influence of the external environment on the internal structure of the cable and protect the normal operation of the cable.

[0067] In addition, in order to further enhance the conductivity and corrosion resistance of the connecting contact piece 10 , an iron sheet layer is fixedly embedded on one side of the connecting contact piece 10 close to the first sliding rod 18 .

[0068] Through the description of the above embodiments, it can be seen that the cable for obtaining hydrogen by electrolysis of water of the present invention has been optimized and innovated in the structure of the connecting contact piece 10 and the selection of cable materials, which greatly improves the conductive stability, corrosion resistance and high temperature resistance of the cable, and provides a more reliable and efficient power transmission solution for the hydrogen production technology by electrolysis of water.

[0069] Working principle: when connecting the cable to the electrode 9, the connector 21 is driven to rotate by the paddle 23 to release the blocking of the connector 21 by the limit block 22, and then the first slide bar 18 and the extrusion sheet 16 are pulled outward to insert the fixed contact sheet 11 into the connector sleeve 8, the connecting contact sheet 10 is in conflict with the fixed contact sheet 11, and the pulling of the first slide bar 18 is released. The first slide bar 18 is reset under the elastic force of the reset spring 19, and the extrusion sheet 16 pushes the connecting contact sheet 10 toward the fixed contact sheet 11, and preliminarily connects the connecting contact sheet 10 with the fixed contact sheet 11, and the extrusion sheet 16 drives the insertion rod 17 to move, and the insertion rod 17 passes through the circular holes 13 on the connecting contact sheet 10 and the fixed contact sheet 11, and further limits the connecting contact sheet 10 and the fixed contact sheet 11 to prevent the connecting contact sheet 10 and the fixed contact sheet 11 from being misaligned and falling off;

[0070] In addition, when the extrusion sheet 16 squeezes the connecting contact sheet 10, the fixed contact sheet 11 and the extrusion sheet 16 squeeze the two spring contacts 15 respectively, so that the conductive stability between the connecting contact sheet 10 and the fixed contact sheet 11 can be increased through the spring contacts 15. Then, the paddle 23 is rotated and braked by the limit block 22 to prevent the first slide bar 18 from moving toward the outside under external force.

[0071] Reference Figure 6-Figure 11 , manufacturing equipment, which is used in the field of cables, this embodiment provides a manufacturing equipment for preparing a connecting contact piece 10 in a cable for obtaining hydrogen by electrolyzing water, and its structure mainly includes the following parts:

[0072] The workbench 24 is firmly set on the ground to support the operation of the entire equipment. A gantry 25 is fixedly installed on the top of the workbench 24, and the gantry 25 spans the workbench 24 to provide a stable support frame. A cylinder 26 is fixed through the gantry 25, and the output shaft of the cylinder 26 is vertically downward and fixedly connected to a punching plate 27. The punching plate 27 is used to perform the punching action.

[0073] Reference Figure 6 and Figure 7 Two circular dies 29 are fixed at the bottom of the punching plate 27 for punching the circular holes 13 on the connecting contact sheet 10. At the same time, a rectangular die 30 is also fixed at the bottom of the punching plate 27 for punching the rectangular holes 12. To ensure stability during the punching process, two second slide bars 28 are fixed at the top of the punching plate 27. The top ends of the two second slide bars 28 slide through the gantry 25 to provide guidance and limit functions.

[0074] Reference Figure 6 , Figure 8 and Fig.10Two fixed platforms 32 are fixedly installed on the top of the workbench 24, and a placement frame 33 is fixed on the top of the two fixed platforms 32 for placing the connecting contacts 10 to be punched.

[0075] Reference Figure 6 and Fig. 9 In order to remove the burrs on the bottom of the contact piece 10 after stamping, the equipment also includes a grinding disc 40 arranged above the workbench 24.

[0076] Reference Figure 7 and Fig. 9 The grinding structure specifically includes: a rotating rod 41 and a screw rod 36 which are rotatably connected to the top of the workbench 24 through a base plate, and the screw rod 36 is located between the two fixed platforms 32. The rotating rod 41 and the screw rod 36 are connected by two sets of transmission components consisting of synchronous wheels and synchronous belts. A one-way bearing 42 is provided on the outer wall of the rotating rod 41, and a gear 43 is fixed to the outer ring of the one-way bearing 42, and the gear 43 is meshed with a rack 31 fixed on one side of the stamping plate 27. A guide rod 37 is also fixed to the top of the workbench 24, and the guide rod 37 is located below the screw rod 36. A moving block 38 is provided on the outer wall sliding sleeve of the guide rod 37, and the moving block 38 is threadedly connected to the screw rod 36. A driving motor 39 is fixed to the top of the moving block 38 through a frame, and the output shaft of the driving motor 39 is fixedly connected to the bottom of the grinding disc 40.

[0077] Specifically, when the stamping plate 27 drives the rack 31 to move upward, the rack 31 drives the rotating rod 41 to rotate counterclockwise through the gear 43 and the one-way bearing 42, and then drives the screw 36 to rotate through the transmission assembly, so that the moving block 38 moves to one side, and at the same time the driving motor 39 is started to drive the grinding disc 40 to rotate, thereby completing the burr removal at the bottom of the contact piece 10.

[0078] Reference Fig.10 and Fig.11 In order to facilitate the removal of the processed connection contact sheet 10, a lifting structure is provided in the two fixed platforms 32, and the lifting structure includes a sliding groove 44 provided on the top of the two fixed platforms 32, and a push rod 45 is slidably connected in the sliding groove 44. A first tension spring 46 is fixed to the bottom of the push rod 45, and the bottom end of the first tension spring 46 is fixedly connected to the bottom inner wall of the sliding groove 44 to provide a reset force for the push rod 45. Both sides of the push rod 45 are rotatably connected with connecting rods 48, and the top ends of the two connecting rods 48 on the same side are rotatably connected to the same U-shaped plate 47. The U-shaped plate 47 slides and extends to one side of the fixed platform 32, and cooperates with the moving block 38.

[0079] Specifically, when the moving block 38 moves outward, it pushes the U-shaped plate 47 to move outward, and then drives the ejector rod 45 to move upward through the connecting rod 48, and ejects the stamped connecting contact piece 10 from the placement frame 33, making it convenient for the staff to take it out.

[0080] Through the coordinated work of the above structures, the manufacturing equipment provided in this embodiment can efficiently and accurately complete the punching and burr removal of the connecting contact piece 10, while facilitating the removal of the product, thereby improving production efficiency and product quality.

[0081] Reference Figure 8 and Fig. 9 Inside the workbench 24, we carefully designed two through holes 35, which are cleverly located on both sides of the screw 36. This layout not only optimizes the equipment structure, but also ensures that the debris generated during the stamping process can be smoothly discharged through these through holes 35, avoiding the impact of debris accumulation on the workbench 24 and subsequent processes.

[0082] Reference Fig. 9 and Fig.10 , we have fixedly embedded magnets 34 on the top of each fixing table 32. These magnets 34 interact with the iron layer on the surface of the connecting contact piece 10 through their strong magnetic attraction, so that the connecting contact piece 10 is firmly adsorbed in the placement frame 33. Especially in the process of removing burrs, the magnetic attraction of the magnets 34 can ensure that the connecting contact piece 10 remains stable on the top of the fixing table 32, providing strong support for the precise operation of the grinding disc 40, and greatly improving the efficiency and quality of removing burrs.

[0083] Example 2

[0084] refer to Fig.12 , improved on the basis of Example 1: In order to further improve the accuracy and stability of the stamping operation, two clearance grooves 49 are designed at the bottom of the stamping plate 27. These two clearance grooves 49 not only optimize the structure of the stamping plate 27, but also provide sufficient room for movement of the components below it. On the top inner wall of each clearance groove 49, we slide a third slide bar 50 through. A rubber pressure block 51 is fixedly connected to the bottom of the third slide bar 50. When the stamping plate 27 is in a non-working state, the rubber pressure block 51 can be stored in the clearance groove 49 to avoid interference with other components of the equipment.

[0085] refer to Fig.12, we have sleeved a second tension spring 52 on the outer wall of each third slide bar 50. The top ends of these second tension springs 52 are fixedly connected to the top of the stamping plate 27, and the bottom ends are fixedly connected to the outer wall of the third slide bar 50. When the stamping plate 27 starts to move downward, the rubber pressing block 51 will first contact the connecting contact piece 10. As the stamping plate 27 continues to press downward, the second tension spring 52 will be stretched and generate a reaction force, which is transmitted to the rubber pressing block 51 through the third slide bar 50, thereby squeezing and fixing the connecting contact piece 10. This design can not only effectively prevent the displacement or falling off of the connecting contact piece 10 during the stamping process, but also improve the accuracy and stability of the stamping operation.

[0086] Through the above specific implementation methods, we have successfully transformed the technical solutions in the claims into practical structures that are feasible and operable, providing strong support for the optimization and upgrading of manufacturing equipment.

[0087] The method for using the manufacturing device comprises the following steps:

[0088] S1. Place the connection contact piece 10 to be processed in the placement frame 33. The output shaft of the cylinder 26 pushes the stamping plate 27 downward, and the stamping plate 27 drives the rack 31 downward. The rack 31 is meshed with the gear 43. The gear 43 drives the one-way bearing 42 to rotate clockwise. At this time, the one-way bearing 42 and the rotating rod 41 are in an active state. As the stamping plate 27 continues to move downward, the rubber pressing block 51 first contacts the connection contact piece 10, and the connection contact piece 10 is squeezed and fixed under the action of the second tension spring 52. Then the stamping plate 27 completes the stamping operation of the circular hole 13 and the rectangular hole 12 through the circular die head 29 and the rectangular die head 30.

[0089] S2. After stamping, burrs appear at the bottom of the connecting contact piece 10, which need to be removed at this time; specifically, the stamping plate 27 drives the rack 31 to move upward, the rack 31 drives the gear 43 and the one-way bearing 42 to rotate counterclockwise, the one-way bearing 42 drives the rotating rod 41 to rotate counterclockwise, the rotating rod 41 drives the screw rod 36 to rotate through the synchronous wheel and the synchronous belt, the screw rod 36 drives the moving block 38 to move to one side, and the driving motor 39 drives the grinding disc 40 to rotate. At this time, the cooperation between the moving block 38 and the grinding disc 40 can remove the burrs at the bottom of the connecting contact piece 10;

[0090] S3. When removing burrs, the magnetic attraction force generated by the magnet 34 on the connecting contact piece 10 can firmly adsorb the connecting contact piece 10 on the top of the fixed platform 32, which is convenient for the grinding disc 40 to remove burrs. After the burr removal is completed, the moving block 38 continues to move, and the moving block 38 pushes the U-shaped plate 47 to move outward. The U-shaped plate 47 drives the push rod 45 to move upward through the connecting rod 48. The push rod 45 pushes the stamped connecting contact piece 10 out of the placement frame 33, which is convenient for the staff to take out. The stamping and deburring operations of the connecting contact piece 10 are completed at one time, and the operation is extremely simple.

[0091] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive motor 39 and the cylinder 26 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0092] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
