Description

Technical Field

[0001] This utility model belongs to the field of support device technology, and relates to a liftable support device for an electrolytic cell. Background Technology

[0002] As the most commercially mature green hydrogen equipment manufacturing technology, alkaline water electrolyzers have seen significant development in all aspects in the past two years. Currently, cylindrical electrolyzers are the most commonly used commercially, secured with bolts. However, during horizontal or vertical installation, due to installation errors or prolonged horizontal placement, the significant weight of the electrolyzer can cause it to tilt or sink in different ways under the influence of gravity.

[0003] In general, electrolytic cells are placed horizontally during final use and transportation. As a piece of extremely heavy equipment, the electrolytic cell itself will sink in some areas under the influence of gravity. Therefore, it is necessary to provide support in appropriate locations during the assembly, horizontal transportation, and operation of the electrolytic cell.

[0004] The utility model patent with authorization announcement number CN201626992U discloses an electrolytic cell support foot. A support beam is connected to the lower part of the electrolytic cell body, a roller support is connected to the lower part of the support beam, and a support base is connected to the lower part of the roller support. This electrolytic cell support foot allows the electrolytic cell support beam to have horizontal displacement, which can greatly reduce the deformation of the support beam, and ultimately reduce the horizontal force of the electrolytic cell on the support base, preventing the support base from cracking.

[0005] During the actual transportation or installation of electrolytic cells, multiple fixed support points may be required, and the heights of these points may differ. Therefore, it is necessary to adjust the height of the electrolytic cell supports and perform secondary fine-tuning of the horizontal position to reduce the horizontal stress exerted by the electrolytic cell on the support base. Existing electrolytic cell support devices cannot be adjusted in height during transportation or assembly, and their excessive size makes them inconvenient to use. Utility Model Content

[0006] The purpose of this invention is to provide a liftable support device for an electrolytic cell, which solves the problem that the support height and position of the electrolytic cell cannot be flexibly changed in the prior art.

[0007] The technical solution adopted in this utility model is:

[0008] The liftable support device for the electrolytic cell includes a support base and an adjusting screw. The upper center of the support base has a threaded channel that mates with the adjusting screw. The upper side wall of the adjusting screw has an adjusting hole. The upper end of the adjusting screw is connected to a support cap. The bottom surface of the support cap has a groove that fits with the top surface of the adjusting screw. The upper surface of the support cap has two semi-cylindrical grooves that are parallel to each other and symmetrical with respect to the axis of symmetry of the support cap. An insulating support column is fixedly connected to the inner surface of each groove. A movable bracket is installed at the lower end of the support base.

[0009] The features of this utility model also include:

[0010] The upper end of the adjusting screw has a cylindrical step with an outer diameter larger than the adjusting screw itself, and adjusting holes are evenly distributed circumferentially on the side wall of the step. The adjusting holes are through holes perpendicular to the adjusting screw. An adjusting handle is inserted into the adjusting hole.

[0011] The support base includes a base plate, with a seamless tube fixed to the middle of the upper surface of the base plate, and a nut placed coaxially at the upper end of the seamless tube. Several mounting holes are evenly distributed on the base plate of the support base.

[0012] The movable support includes a connecting plate and a roller mechanism fixedly connected to the bottom surface of the connecting plate. The connecting plate has several mounting holes evenly distributed, and the positions of these holes correspond to those on the support base. The roller mechanism consists of two sets of connecting rods, each equipped with a pair of movable rollers, arranged side-by-side. The roller mechanism also includes several casters.

[0013] The beneficial effects of this utility model are:

[0014] The adjustable support device of this invention has an adjustable support height, a stable structure, adaptability to various sites, and compensation for uneven ground. In addition, it is small in size and can achieve multi-point support under the electrolytic cell. The support height can be adjusted and the horizontal position can be adjusted a second time to ensure the stability of the electrolytic cell and the uniform force distribution.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 As shown, this utility model relates to a liftable support device for an electrolytic cell, including a support base 1 and an adjusting screw 2. The upper middle part of the support base 1 has a threaded channel that mates with the adjusting screw 2. The upper side wall of the adjusting screw 2 has an adjusting hole 9. The upper end of the adjusting screw 2 is connected to a support cap 3. The bottom surface of the support cap 3 has a groove that fits with the top surface of the adjusting screw 2. The upper surface of the support cap 3 has two semi-cylindrical grooves that are parallel to each other and symmetrical with respect to the axis of symmetry of the support cap 3. An insulating support column 5 placed horizontally is fixedly connected to the inner surface of each groove. A movable bracket is installed at the lower end of the support base 1.

[0020] The support cap 3 is fitted with the upper end of the adjusting screw 2 with a clearance, so that the adjustment screw 2 will not cause the support cap 3 to rotate at the same time, thus maintaining the relative stability of the position of the support cap 3.

[0021] The upper end of the adjusting screw 2 has a cylindrical step with an outer diameter larger than that of the adjusting screw 2, and adjusting holes 9 are evenly distributed around the side wall of the step. The adjusting holes 9 are through holes perpendicular to the adjusting screw 2. The adjusting handle 4 is inserted into the adjusting hole 9.

[0022] The support base 1 includes a base plate, on the upper surface of which a seamless tube is fixedly connected in the middle, and a nut placed coaxially is fixedly connected to the upper end of the seamless tube. Several mounting holes are evenly distributed on the base plate of the support base 1.

[0023] The movable support includes a connecting plate 6 and a roller mechanism fixedly connected to the bottom surface of the connecting plate 6. The connecting plate 6 has several mounting holes evenly distributed on it, and the positions of these mounting holes correspond to the mounting holes on the support base 1. The roller mechanism consists of two sets of connecting rods 7, each equipped with a pair of movable rollers 8, arranged side-by-side. The roller mechanism also includes several casters.

[0024] Working principle:

[0025] like Figure 2 As shown, when in use, several of the adjustable support devices of the electrolytic cell of this utility model are placed at the position of the electrolytic cell 10 that requires auxiliary support. The adjustment handle 4 or a screwdriver or other tools are inserted into the adjustment hole. The adjustment screw 2 is rotated, and the height of the support cap 3 moves up and down accordingly. After reaching the required height, the movable bracket at the lower end of the support base 1 is slightly moved to adjust the horizontal position a second time, thereby reducing the horizontal stress on the adjustment screw 2.

[0026] The electrolytic cell is similar to a cylinder weighing 70 tons. The adjusting screw 2 and the support cap 3 are designed with a clearance fit. This prevents the support cap 3 from moving when the height of the support cap 3 needs to be adjusted again after the relative positions of the electrolytic cell and the support cap have been adjusted, thus avoiding excessive deviation of the support cap 3 from its direction.

[0027] Example 1

[0028] In this embodiment, the liftable support device for the electrolytic cell includes a support base 1 and an adjusting screw 2. The upper center of the support base 1 has a threaded channel that mates with the adjusting screw 2. Rotating the adjusting screw 2 allows for vertical adjustment. The required load-bearing strength of the thread is calculated based on the weight of the electrolytic cell, thus allowing for the selection of a suitable thread.

[0029] The upper side wall of the adjusting screw 2 has an adjusting hole. By inserting a screwdriver or other tool into the adjusting hole, the adjusting screw 2 can be rotated. Lubricant can be applied to the threads during use to facilitate the rotation of the adjusting screw 2.

[0030] The upper end of the adjusting screw 2 is movably connected to the support cap 3. The bottom surface of the support cap 3 has a cylindrical groove that fits with the upper end of the adjusting screw 2 with a clearance. When the adjusting screw 2 rotates, the support cap 3 will not rotate at the same time, thus maintaining the relative stability of the position of the support cap 3.

[0031] The upper surface of the support cap 3 has two semi-cylindrical grooves. The two grooves are parallel to each other and symmetrically arranged with respect to the axis of symmetry of the support cap. An insulating support column 5 is fixedly connected to the inner surface of each groove, so that a through groove is formed between the two insulating support columns 5. The material of the insulating support column 5 is preferably nylon.

[0032] During operation, a significant voltage difference exists between the electrodes in an electrolytic cell. The insulating support column 5 effectively isolates the current conduction between the electrodes and the cell body, preventing energy loss and safety hazards caused by leakage. In some electrolytic processes with high requirements for energy efficiency, the excellent insulation performance of the insulating support column ensures that most of the electrical energy is used for the electrolytic reaction, thus improving energy utilization efficiency.

[0033] Compared to traditional sliding supports, the friction coefficient of the insulating support columns is significantly reduced. This greatly reduces mechanical wear caused by the support structure during electrolytic cell operation, thus extending the service life of the electrolytic cell.

[0034] Insulating support columns can evenly distribute the weight of the electrolytic cell across multiple support points, avoiding structural deformation and wear caused by excessive local stress. This uniform stress distribution is especially important for large electrolytic cells, ensuring that the electrolytic cell maintains a stable structure and performance during long-term use.

[0035] When the device supports the electrolytic cell, the insulating support column 5 is deformed due to the pressure of the electrolytic cell, and there is a through groove between the two insulating support columns 5, which can improve the stability of the support action and play an insulating role.

[0036] During electrolysis, a large amount of heat is generated, causing the temperature around the electrolytic cell to rise. The insulating support columns are usually made of high-temperature resistant materials, which can maintain good insulation and mechanical properties in high-temperature environments, ensuring the normal operation of the electrolytic cell. The electrolyte used in the electrolytic cell is usually corrosive. The insulating support columns are made of specially treated or corrosion-resistant materials, which can resist the corrosion of the electrolyte and ensure long-term use in harsh chemical environments.

[0037] The lower end of the support base 1 is equipped with a movable bracket, which is connected by detachable means such as snap-fit ​​connection, bolt connection, or plug-in connection, or by fixed connection such as welding or riveting. This allows the movable bracket to be adjusted horizontally a second time after the device has been adjusted to the height, reducing the stress on the adjusting screw and increasing the service life of the adjusting screw.

[0038] In use, place several of the adjustable support devices of the electrolytic cell of this utility model at the position of the electrolytic cell 10 that requires auxiliary support, insert a screwdriver or other tools into the adjustment hole, rotate the adjustment screw 2, and the height of the support cap 3 will move up and down accordingly. After reaching the required height, slightly move the movable bracket at the lower end of the support base 1 to adjust the horizontal position a second time and reduce the horizontal stress on the adjustment screw 2.

[0039] Example 2

[0040] In this embodiment, the liftable support device for the electrolytic cell includes a support base 1 and an adjusting screw 2. The upper middle part of the support base 1 has a threaded channel that mates with the adjusting screw 2. The upper side wall of the adjusting screw 2 has an adjusting hole 9. The upper end of the adjusting screw 2 is connected to a support cap 3. The bottom surface of the support cap 3 has a groove that fits with the top surface of the adjusting screw 2. The upper surface of the support cap 3 has two semi-cylindrical grooves that are parallel to each other and symmetrical with respect to the axis of symmetry of the support cap 3. An insulating support column 5 is fixedly connected to the inner surface of each groove. A movable bracket is installed at the lower end of the support base 1.

[0041] The support base 1 includes a base plate, on the upper surface of which a seamless tube is welded in the middle, and a nut placed coaxially is welded to the upper end of the seamless tube.

[0042] The base plate effectively increases the bearing area of ​​the support base 1, making the base more stable in supporting the electrolytic cell. The seamless tube provides the internal space required for the adjustment screw 2 to move up and down, ensuring support while reducing the overall weight of the base due to its structural characteristics. The nut on the support mainly serves to cooperate with the screw, enabling the support to have a lifting function. Directly welding the nut replaces the thread machining step, simplifying the base machining difficulty and reducing machining costs.

[0043] In use, place several of the adjustable support devices of the electrolytic cell of this utility model at the position of the electrolytic cell 10 that requires auxiliary support, insert a screwdriver or other tools into the adjustment hole, rotate the adjustment screw 2, the adjustment screw 2 moves up and down in the seamless tube of the base, and the height of the support cap 3 moves up and down accordingly. After reaching the required height, slightly move the movable bracket at the lower end of the support base 1 to adjust the horizontal position a second time and reduce the horizontal stress on the adjustment screw 2.

[0044] Example 3

[0045] In this embodiment, the liftable support device for the electrolytic cell includes a support base 1 and an adjusting screw 2. The upper middle part of the support base 1 has a threaded channel that mates with the adjusting screw 2. The upper side wall of the adjusting screw 2 has an adjusting hole 9. The upper end of the adjusting screw 2 is connected to a support cap 3. The bottom surface of the support cap 3 has a groove that fits with the top surface of the adjusting screw 2. The upper surface of the support cap 3 has two semi-cylindrical grooves that are parallel to each other and symmetrical with respect to the axis of symmetry of the support cap 3. An insulating support column 5 is fixedly connected to the inner surface of each groove. A movable bracket is installed at the lower end of the support base 1.

[0046] The adjustment hole is a through hole perpendicular to the adjustment screw 2.

[0047] Through holes provide a direct operating channel for adjusting tools. Compared to closed adjustment holes, through holes can accommodate a wider variety of tools and ensure that the tools have sufficient room to move during operation.

[0048] Over time, dust and debris may enter the regulating orifice. The open-hole design makes cleaning easier. A compressed air spray gun or small cleaning tools can be used to remove debris directly through the orifice. In contrast, a closed regulating orifice may allow debris to accumulate inside, making it difficult to clean and increasing the risk of wear and jamming of the regulating components.

[0049] In use, place several of the adjustable support devices of the electrolytic cell of this utility model at the position of the electrolytic cell 10 that requires auxiliary support, insert a long rod or other tool through the adjustment hole, and push one or both ends of the long rod to rotate the adjustment screw 2, so that the adjustment screw 2 moves up and down, and the height of the support cap 3 moves up and down accordingly. After reaching the required height, slightly move the movable bracket at the lower end of the support base 1 to adjust the horizontal position a second time, thereby reducing the horizontal stress on the adjustment screw 2.

[0050] Example 4

[0051] In this embodiment, the liftable support device for the electrolytic cell includes a support base 1 and an adjusting screw 2. The upper middle part of the support base 1 has a threaded channel that mates with the adjusting screw 2. The upper side wall of the adjusting screw 2 has an adjusting hole 9. The upper end of the adjusting screw 2 is connected to a support cap 3. The bottom surface of the support cap 3 has a groove that fits with the top surface of the adjusting screw 2. The upper surface of the support cap 3 has two semi-cylindrical grooves that are parallel to each other and symmetrical with respect to the axis of symmetry of the support cap 3. An insulating support column 5 is fixedly connected to the inner surface of each groove. A movable bracket is installed at the lower end of the support base 1.

[0052] The upper end of the adjusting screw 2 has a cylindrical step with an outer diameter larger than that of the adjusting screw 2, and adjusting holes 9 are evenly distributed around the side wall of the step. Adjusting handles 4 are inserted into the adjusting holes, and there may be one or two symmetrical adjusting handles 4.

[0053] The protruding step increases the diameter of the upper cylinder of the adjusting screw 2, which increases the torque when the adjusting screw 2 is rotated by the adjusting handle 4. Inserting two symmetrical adjusting handles 4 can further increase the torque and facilitate the rotation of the adjusting screw 2.

[0054] Increasing the torque of the adjusting handle makes it easier for operators to turn it during operations such as adjusting the height of the electrolytic cell support frame. According to the lever principle, during adjustment, for the same resistance, increasing the torque reduces the force required. This is highly advantageous for situations requiring frequent adjustments to the support frame height or those requiring significant force. It also reduces the physical burden on operators in cases where the support frame has been left unadjusted for a long time, leading to rust or jamming.

[0055] In use, place several of the adjustable support devices of the electrolytic cell of this utility model at the position of the electrolytic cell 10 that requires auxiliary support, insert the adjustment handle 4 or a screwdriver into the adjustment hole, rotate the adjustment screw 2, and the height of the support cap 3 will move up and down accordingly. After reaching the required height, slightly move the movable bracket at the lower end of the support base 1 to adjust the horizontal position a second time and reduce the horizontal stress on the adjustment screw 2.

An insulating support column 5 is fixedly connected to the inner surface of each groove. A movable bracket is installed at the lower end of the support base 1.

[0058] The support base 1 includes a base plate, on the upper surface of which a seamless tube is welded in the middle. A nut placed coaxially is welded to the upper end of the seamless tube. Several mounting holes are evenly distributed on the base plate of the support base 1.

The connecting plate 6 is connected to the base plate using bolts and nuts. The roller mechanism consists of two connecting rods 7, each equipped with two movable rollers 8, arranged side-by-side.

[0060] Common roller materials include steel, nylon, and polyurethane. Steel rollers are strong but may generate noise and cause wear on the ground. Nylon and polyurethane rollers are relatively lightweight, quieter, and offer better protection for the ground. The appropriate roller material and size should be selected based on the total weight of the electrolytic cell and its supporting device.

[0061] Brakes or braking mechanisms can be added to the rollers to quickly lock them in place when fixed support is required.
