Description

Technical Field

[0001] This utility model relates to the field of solid oxide battery system technology, specifically a pipeline connection structure for a solid oxide battery system. Background Technology

[0002] Solid oxide fuel cell (SOFC) systems are high-efficiency energy systems that use solid oxides as electrolytes and achieve energy conversion through electrochemical reactions. They can be used as fuel cells to generate electricity (directly converting chemical energy into electrical energy) or as electrolyzers to produce hydrogen (converting electrical energy into chemical energy). They have significant advantages such as high efficiency, cleanliness, and wide fuel adaptability. They are a new type of energy conversion device that can be used to build distributed power generation systems and have great commercial application prospects.

[0003] Solid oxide fuel cell (SOFC) systems operate at high temperatures, typically between 700 and 850°C. Pipelines within these systems are usually connected using flanges and bolts. However, traditional bolts only have ordinary threads, resulting in insufficient friction. The nuts are prone to loosening and falling off due to vibration or inertia, leading to connection failure and inadequate shock resistance, posing safety hazards during operation. Furthermore, the connecting flanges cannot regulate internal flow. Therefore, we propose a new pipeline connection structure for solid oxide fuel cell systems to address these shortcomings.

An annular groove is provided on the opposite side of the first flange and the second flange. A sealing ring is installed inside the annular groove. An adjustment component is disposed on one side of the first flange.

[0008] The present invention is further configured such that the connecting assembly includes a bolt, a threaded portion, an opening, and abutment strips. The outer side of the bolt is inserted into the interior of the through hole, the threaded portion is located on the outer side of the bolt, the opening is located on the outer side of the bolt, and the opening divides one end of the bolt into several abutment strips.

[0009] The present invention is further configured such that the connecting assembly includes a nut and a screw, wherein the inner wall of the nut is threadedly connected to the outer side of the bolt through a threaded portion, and the outer side of the screw is threadedly connected to the inner wall of the bolt.

[0010] The present invention is further configured such that the connecting assembly includes an adjustment hole, an extrusion block, and a top cover. The adjustment hole is opened at one end of the bolt, one end of the extrusion block is fixedly connected to one end of the screw, and the extrusion block and the adjustment hole are truncated cones with a wider outer side and a narrower inner side. One side of the top cover is fixedly connected to the other end of the screw, and a screw groove is opened on the other side of the top cover.

[0011] The present invention is further configured such that the adjusting assembly includes a rotating rod, a disc, and a fixing ring, the outer side of the rotating rod is rotatably connected to one side of the first flange, the top end of the disc is fixedly connected to the bottom end of the rotating rod, and the inner wall of the fixing ring is fixedly connected to the outer side of the rotating rod.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-6 As shown, this utility model provides a technical solution: a pipeline connection structure for a solid oxide battery system, including a first flange 1 and a second flange 2. The first flange 1 and the second flange 2 are disc-shaped and arranged opposite to each other. An insulating ceramic sheet 3 is arranged between the first flange 1 and the second flange 2. A gas pipe 4 is fixedly connected inside the first flange 1 and the second flange 2. Through holes 5 are opened at the four outer corners of the first flange 1, the second flange 2 and the insulating ceramic sheet 3. A connecting component 6 is arranged inside the through holes 5. An annular groove 7 is opened on the opposite side of the first flange 1 and the second flange 2. A sealing ring 8 is installed inside the annular groove 7. An adjusting component 9 is arranged on one side of the first flange 1.

[0027] Two air pipes 4 are connected by a first flange 1 and a second flange 2. An insulating ceramic sheet 3 is provided between the first flange 1 and the second flange 2 to provide insulation. The first flange 1 and the second flange 2 can be connected and fixed by the connecting component 6. After connection, the sealing ring 8 is squeezed to provide a seal. The flow rate inside the flange can be adjusted by the adjusting component 9.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the connecting assembly 6 includes a bolt 601, a threaded portion 602, an opening 603, an abutment strip 604, a nut 605, a screw 606, an adjusting hole 607, a pressing block 608, and a top cover 609. The outer side of the bolt 601 is inserted into the through hole 5. The threaded portion 602 is located on the outer side of the bolt 601. The opening 603 is located on the outer side of the bolt 601, dividing one end of the bolt 601 into several abutment strips 604. The nut... The inner wall of 605 is threaded to the outer side of bolt 601 through threaded part 602. The outer side of screw 606 is threaded to the inner wall of bolt 601. Adjustment hole 607 is opened at one end of bolt 601. One end of extrusion block 608 is fixedly connected to one end of screw 606. The shape of extrusion block 608 and adjustment hole 607 is a frustum shape with a wider outer side and a narrower inner side. One side of top cover 609 is fixedly connected to the other end of screw 606. The other side of top cover 609 is provided with screw groove.

[0029] By rotating the top cover 609, the screw 606 is driven to rotate and move horizontally, which in turn drives the extrusion block 608 to move horizontally. During the movement, the extrusion block 608 expands the abutment strip 604, so that the abutment strip 604 abuts against the inner wall of the nut 605, tightening the nut 605 onto the bolt 601, which can improve the seismic performance between the two flanges.

[0030] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the adjusting assembly 9 includes a rotating rod 901, a disc 902, a fixing ring 903, a positioning groove 904, a sliding rod 905, a positioning rod 906, a spring 907, and a push plate 908. The outer side of the rotating rod 901 is rotatably connected to one side of the first flange 1. The top end of the disc 902 is fixedly connected to the bottom end of the rotating rod 901. The inner wall of the fixing ring 903 is fixedly connected to the outer side of the rotating rod 901. Several positioning grooves 904 are provided on the fixing ring 903. On the outside, the outer side of the sliding rod 905 is slidably connected to the outer side of the first flange 1, the outer side of the positioning rod 906 is fixedly connected to one end of the sliding rod 905, the positioning rod 906 is slidably inserted into the inside of one of the positioning grooves 904, the spring 907 is sleeved on the outer side of the sliding rod 905, one end of the spring 907 is fixedly connected to the outer side of the positioning rod 906, the other end of the spring 907 is fixedly connected to the inner wall of the first flange 1, and the outer side of the push plate 908 is fixedly connected to one end of the sliding rod 905.

[0031] By pulling the push plate 908 outward, the sliding rod 905 and the positioning rod 906 move horizontally, causing the spring 907 to be compressed. At the same time, one end of the positioning rod 906 disengages from the positioning groove 904, releasing the restriction on the fixed ring 903, and thus releasing the restriction on the rotating rod 901. Then, the operator can rotate the rotating rod 901, causing the disc 902 to rotate. The flow rate inside the flange can be adjusted by the rotation angle of the disc 902.

[0032] Working principle: In use, the two air pipes 4 are connected through the first flange 1 and the second flange 2. An insulating ceramic sheet 3 is set between the first flange 1 and the second flange 2 to provide insulation. One end of the bolt 601 is inserted into the through hole 5 in the first flange 1 and the second flange 2, and then the nut 605 is installed on one end of the bolt 601, so that one side of the nut 605 fits against the second flange 2, and the first flange 1 and the second flange 2 are initially fixed. Then, a screwdriver is inserted into the screw groove opened on one side of the top cover 609, and the top cover 609 is rotated by rotating the screwdriver, which in turn drives the screw rod 606 to rotate and move horizontally. At the same time, the pressing block 608 moves horizontally, so that the pressing block 608 expands the abutment strip 604 during the movement, so that the abutment strip 604 abuts against the inner wall of the nut 605, tightening the nut 605 on the bolt 601, which can improve the seismic performance between the two flanges.

[0033] After the first flange 1 and the second flange 2 are connected, the sealing ring 8 is compressed, which plays a sealing role. When it is necessary to adjust the internal flow rate, firstly, by pulling the push plate 908 outward, the sliding rod 905 and the positioning rod 906 are moved horizontally, causing the spring 907 to be compressed. At the same time, one end of the positioning rod 906 is disengaged from the positioning groove 904, releasing the restriction on the fixed ring 903, and then releasing the restriction on the rotating rod 901. Then, the operator can rotate the rotating rod 901 to drive the disc 902 to rotate. The flow rate inside the flange is adjusted by the rotation angle of the disc 902. After adjusting to the appropriate position, the push plate 908 is released. At this time, the spring 907 is reset due to the force, which drives the positioning rod 906 to re-insert into the corresponding positioning groove 904, fixing the position of the disc 902 and completing the adjustment operation. By setting multiple positioning grooves 904, the flow rate can be adjusted in multiple stages.

[0034] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
