Description

Technical Field

[0001] This application relates to the technical field of support equipment, and particularly relates to an electrolyzer support device. Background Art

[0002] The electrolytic hydrogen production technology is a process of decomposing water into hydrogen and oxygen by electrolysis. The existing hydrogen production technology routes mainly include: alkaline water electrolysis for hydrogen production, PEM water electrolysis for hydrogen production, anion exchange membrane electrolysis for hydrogen production, solid oxide water electrolysis for hydrogen production, etc. Among them, the alkaline water electrolysis for hydrogen production has developed relatively maturely and has become a relatively widely used hydrogen production method at present.

[0003] The electrolyzer is the most core equipment in the alkaline water electrolysis for hydrogen production method. It consists of 200 - 400 electrolytic cells, a fastening system, and end plates. Its aspect ratio is too large. Taking the electrolyzer for hydrogen production with a water production rate of 1000 Nm 3 / h as an example, its length is generally 6m, its diameter is generally 2m, and its weight is close to 60 tons. Only a dozen tie bolts and end plates are used to fasten hundreds of electrolytic cells, and the central part of the electrolyzer is insufficiently supported. It is extremely easy for the central part to sag due to temperature rise during the operation of the electrolyzer, which will seriously cause the sealing gasket of the electrolyzer to fail and leak, and then lead to the shutdown of the electrolyzer.

[0004] To avoid the occurrence of the above-mentioned adverse consequences, the existing method is to set a support device at the bottom of the electrolyzer to directly support the electrolyzer, or to set a cross beam along the length direction of the electrolyzer at the bottom of the electrolyzer, and then use a support device to indirectly support the electrolyzer by supporting the cross beam. The above indirect support method is used more because it can support the whole electrolyzer. However, due to the large overall weight of the electrolyzer, the support structure mostly uses metals or masonry with high strength and large thickness, but this will make the support structure heavy, difficult to move, and difficult to adjust the support height. Utility Model Content

[0005] This application provides an electrolyzer support device to solve the problem that the support structure for supporting the electrolyzer mostly uses metal structures with high strength and large thickness, resulting in a heavy support structure, difficult to move, and difficult to adjust the support height.

[0006] This application provides an electrolyzer support device, including:

[0007] A mobile trolley, on which a bottom plate is arranged, and a support plate is arranged on the bottom plate. The support plate is rotatably connected to the bottom plate;

[0008] A telescopic structure, which is arranged on the support plate, and the upper end of the telescopic structure is connected to a load-bearing plate;

[0009] The receiving part is matched and linked with the slide rail on the load-bearing plate, and a groove is penetrated through the receiving part for matching the shape of the bottom cross beam of the electrolytic cell.

[0010] Mounting holes are respectively arranged at the positions on both sides of the groove of the receiving part for mounting insulating blocks.

[0011] Optionally, the longitudinal section of the receiving part along the groove is composed of two symmetrical clamping blocks;

[0012] The mounting holes are respectively arranged at the tops of each clamping block;

[0013] The two clamping blocks are connected by an adjusting bolt and at least one fastening bolt;

[0014] The adjusting bolt and the fastening bolt are arranged between the bottom of the groove opened on the clamping block and the bottom of the clamping block.

[0015] Optionally, the spiral directions of the threads of the adjusting bolt that match the two clamping blocks are opposite.

[0016] Optionally, an even number of telescopic structures are symmetrically arranged, and the load-bearing plate is composed of two symmetrical unit plates;

[0017] Each unit plate is supported by the same number of telescopic structures;

[0018] The two unit plates are connected by fasteners.

[0019] Optionally, supports for supporting the telescopic structures are respectively arranged at both ends of the upper part of the mobile trolley;

[0020] The bottom of one side of the telescopic structure close to the support is hinged to the support plate.

[0021] Optionally, clamping grooves are opened at the tops of the two clamping blocks for matching with the telescopic structure after being turned over and laid flat.

[0022] Optionally, an anti-slip layer is fixed on the inner wall of the groove penetrated through the receiving part.

[0023] For the electrolytic cell support device provided by the present application, by using a mobile trolley as an overall support and moving mechanism, mobility is provided for the device. At the same time, telescopic structures are arranged to realize the adjustment of the height of the receiving part, and mounting holes are opened at the top of the receiving part to mount insulating blocks as direct contact components with the cross beam, which can prevent the safety risk caused by electric leakage of the electrolytic cell while providing support. Through the combined use of the above structures, the support device of the present application realizes the support of the electrolytic cell, overcoming the disadvantages that the support structures for supporting the electrolytic cell mostly use metals or masonry with high strength and large thickness, resulting in large weight of the support structure, inconvenient movement, and difficulty in adjusting the support height.

Detailed implementation manners

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be described clearly and completely below. Apparently, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts also belong to the scope of protection of this application.

[0038] As Figure 1 and Figure 2 shown, this application provides an electrolytic cell support device, including:

[0039] A moving trolley 1, on which a bottom plate 11 is provided, and a support plate 12 is provided on the bottom plate 11. The support plate 12 is rotatably connected to the bottom plate 11;

[0040] A telescopic structure 2, which is provided on the support plate 12, and the upper end of the telescopic structure 2 is connected to a load-bearing plate 21;

[0041] A receiving member 3, which is matched and connected with the slide rail 211 on the load-bearing plate 21. A groove 100 is provided through the receiving member 3 for matching the shape of the bottom cross beam of the electrolytic cell;

[0042] Mounting holes 101 are respectively provided at the positions on both sides of the groove 100 of the receiving member 3 for mounting insulating blocks 30.

[0043] In this application, the structure of the moving trolley 1 is similar to that of a tank carrier. The rotatable connection between the support plate 12 and the bottom plate 11 can be realized through Figure 3 a structure. Specifically, the rotating structure includes an outer tube and an inner tube arranged coaxially, and the two are rotatably connected (for example, realized by a structure similar to a bearing). The outer tube is fixedly connected to the moving trolley 1. The length of the inner tube is longer than that of the outer tube (that is, it extends out of the bottom plate 11 of the moving trolley 1), and the top of the inner tube is fixedly connected to the lower surface of the support plate 12. In the figure, for clearly showing each structure, the insulating block 30 is only shown in the mounting hole 101 on one side.

[0044] As Figure 4 and Figure 5 shown, the insulating block 30 can be a trapezoidal block with an inclined upper surface, or a shape with a semi-circular top, or other shapes suitable for support.

[0045] In this application, during use, the receiving member 3 is matingly connected with the slide rail 211 on the load-bearing plate 21, the insulating block 30 is installed in the mounting hole 101, and then the mobile trolley 1 is moved under the cross beam to be supported (the ground should be as flat as possible). Rotate the support plate 12 to adjust the direction of the body of the mobile trolley 1 so that the extending direction of the supported device is perpendicular to the traveling direction of the mobile trolley 1 to prevent the support device from slipping during use. Then, adjust the height of the receiving member 3 by adjusting the telescopic structure 2 (a hydraulic cylinder or an electric cylinder in this application) so that the insulating block 30 approaches the bottom of the cross beam to be supported and the bottom of the insulating block 30 closely adheres to the outer periphery of the cross beam to be supported, thereby achieving the support of the cross beam.

[0046] This application provides an electrolytic cell support device. By using the mobile trolley 1 as the overall support and moving mechanism, mobility is provided for this device. At the same time, the telescopic structure 2 is provided to adjust the height of the receiving member 3, and the insulating block 30 is installed in the mounting hole 101 opened at the top of the receiving member 3 as the direct contact component with the cross beam. While providing support, it can also prevent the safety risk brought by the leakage of electricity from the electrolytic cell. The support device of this application realizes the support of the electrolytic cell through the combined use of the above structures, overcoming the disadvantages that the support structures for supporting electrolytic cells mostly use metals or masonry with high strength and large thickness, resulting in large weight of the support structure, inconvenient movement, and difficulty in adjusting the support height.

[0047] As Figure 6 shown, optionally, the receiving member 3 is composed of two symmetric clamping blocks 31 along the longitudinal section of the groove 100;

[0048] The mounting holes 101 are respectively opened at the top of each clamping block 31;

[0049] The two clamping blocks 31 are connected by an adjusting bolt 32 and at least one fastening bolt 33;

[0050] The adjusting bolt 32 and the fastening bolt 33 are arranged between the bottom of the groove 100 opened on the clamping block 31 and the bottom of the clamping block 31.

[0051] In this application, during use, the insulating block 30 is installed in the mounting hole 101, and then the distance between the two clamping blocks 31 is adjusted by screwing the adjusting bolt 32 to ensure that the distance of the insulating block 30 is smaller than the outer diameter of the cross beam to be supported. Then, the height of the receiving member 3 is adjusted by adjusting the telescopic structure 2 (a hydraulic cylinder or an electric cylinder in this application) so that the insulating block 30 approaches the bottom of the cross beam to be supported, and then the fastening bolt 33 is screwed to make the insulating block 30 tightly support the cross beam.

[0052] In another achievable manner, if the cross beam is relatively thin such that the distance between the insulating blocks 30 is greater than the outer diameter of the cross beam no matter how it is adjusted, the support plate 12 can be rotated at this time so that the line connecting the insulating blocks 30 on both sides is parallel to the line where the cross beam is located.

[0053] The cross beam can also be supported by the groove 100. At this time, the adjustment method is to adjust the distance between the two clamping blocks 31 by screwing the adjustment bolt 32 so that the groove 100 formed by combining the two clamping blocks 31 closely adheres to the outer circumference of the cross beam to be supported to support the cross beam.

[0054] Such as Figure 6 shown, optionally, the spiral directions of the threads on the adjustment bolt 32 that match the two clamping blocks 31 are opposite.

[0055] In this application, the spiral directions of the threads on the adjustment bolt 32 that match the two clamping blocks 31 are opposite. This setting enables the two clamping blocks 31 to move towards each other or away from each other simultaneously to ensure the synchronism of their movement.

[0056] Such as Figure 7 shown, optionally, an even number of telescopic structures 2 are symmetrically arranged, and the bearing plate 21 is composed of two symmetrical unit plates 212;

[0057] Each unit plate 212 is supported by the same number of telescopic structures 2;

[0058] The two unit plates 212 are connected by fasteners 213.

[0059] During use, the two unit plates 212 are assembled into the bearing plate 21 through the fasteners 213, and the receiving member 3 is connected in a matching manner with the slide rail 211 on the bearing plate 21 for use. In this application, the fasteners 213 include a pair of fixing screws respectively arranged on one side of the same vertical plane of the two unit plates 212. The pair of fixing screws are connected by a connecting rib, and through holes matching the outer diameter of the fixing screws are arranged at both ends of the connecting rib. During use, the pair of fixing screws are respectively passed through the through holes at both ends of the connecting rib and connected to the unit plate 212 to achieve the assembly of the unit plate 212. In specific use, other parts that can achieve the functions of the fasteners 213 can also be selected according to actual situations.

[0060] Such as Figure 8 shown, optionally, support frames 13 for supporting the telescopic structures 2 are respectively arranged at both ends of the upper part of the mobile trolley 1;

[0061] The bottom of one side of the telescopic structure 2 close to the support frame 13 is hinged to the support plate 12.

[0062] In this application, the bottom of one side of the telescopic structure 2 close to the support frame 13 is hinged to the support plate 12, so that it can be horizontally placed through the hinge to achieve folding and reduce space.

[0063] As Figure 8 and Figure 9 shown, optionally, the tops of the two clamping blocks 31 are provided with clamping grooves for matching with the telescopic structure 2 after being turned over and laid flat.

[0064] In this application, the tops of the two clamping blocks 31 are provided with clamping grooves to facilitate their matching with the telescopic structure 2 after being turned over and laid flat, so as to realize the folding of the device and reduce the occupied space.

[0065] As Figure 10 shown, optionally, an anti-slip layer 22 is fixed to the inner wall of the groove 100 penetrating through the receiving member 3.

[0066] In this application, the anti-slip layer 22 can be made of an insulating material with high friction such as rubber, so as to increase its manufacturing stability.

[0067] Embodiment 1

[0068] An electrolytic cell support device works as follows:

[0069] During use, the receiving member 3 is connected in a matching manner with the slide rail 211 on the load-bearing plate 21, the insulating block 30 is installed in the installation hole 101, and then the mobile trolley 1 is moved under the cross beam to be supported (the ground is preferably horizontal). Rotate the support plate 12 to adjust the direction of the body of the mobile trolley 1 so that the extending direction of the supported equipment is perpendicular to the traveling direction of the mobile trolley 1 to prevent the support device from slipping during use; then adjust the distance between the two clamping blocks 31 by screwing the adjusting bolt 32 to ensure that the distance between the insulating blocks 30 is smaller than the outer peripheral shape of the supported cross beam. Then adjust the height of the receiving member 3 by adjusting the telescopic structure 2 (a hydraulic cylinder or an electric cylinder in this application) so that the groove 100 opened on the receiving member 3 is close to the bottom of the cross beam to be supported. Then screw the adjusting bolt 32 to adjust the distance between the two clamping blocks 31 so that the insulating block 30 is close to the bottom of the cross beam to be supported. Then screw the fastening bolt 33 to make the insulating block 30 tightly support the cross beam.

[0070] If the cross beam is so thin that the distance between the insulating blocks 30 cannot be adjusted to be smaller than the outer diameter of the cross beam anyway, at this time, the support plate 12 can be rotated so that the connection line between the insulating blocks 30 on both sides is parallel to the straight line where the cross beam is located to achieve the support of the cross beam.

[0071] The crossbeam can also be supported by the groove 100. At this time, the adjustment method is to adjust the distance between the two clamping blocks 31 by screwing the adjustment bolt 32, so that the groove 100 formed by the combination of the two clamping blocks 31 closely adheres to the outer periphery of the crossbeam to be supported to support the crossbeam.

[0072] Embodiment 2

[0073] An electrolytic cell support device has the following working process:

[0074] When in use, rotate the telescopic structure 2 around the hinge to the upright state, then fasten the two unit plates 212 together to form the load-bearing plate 21 through the fastener 213, connect the receiving member 3 to match the slide rail 211 on the load-bearing plate 21, install the insulating block 30 in the mounting hole 101, then move the mobile trolley 1 under the crossbeam to be supported, and rotate the support plate 12 to adjust the body direction of the mobile trolley 1 to prevent the support device from slipping during use; then adjust the distance between the two clamping blocks 31 by screwing the adjustment bolt 32 to ensure that the distance between the insulating blocks 30 is less than the outer diameter of the crossbeam to be supported, and then synchronously adjust the telescopic structure 2 (a hydraulic cylinder or an electric cylinder in this application) to make the two unit plates 212 rise and fall synchronously, so as to adjust the height of the receiving member 3, make the insulating block 30 close to the bottom of the crossbeam to be supported, and then screw the fastening bolt 33 to make the insulating block 30 tightly support the crossbeam.

[0075] When it is necessary to disassemble the support device for easy storage, take out the insulating block 30, remove the receiving member 3 from one side along the slide rail 211, then release the connection of the fastener 213 to the two unit plates 212, then retract the telescopic structure 2, and rotate the telescopic structure 2 along its hinge to the horizontal state, so that the horizontally placed telescopic structure 2 can be placed on the support frame 13. Then turn the receiving member 3 so that the card slot opened at its top is in clamping match with the horizontally placed telescopic structure 2, thereby realizing the folding of the support device to reduce its occupied space.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
