Description

Technical Field

[0001] This invention relates to the field of Stirling engine support technology, specifically to a positioning and support device for the heated end of a Stirling engine. Background Technology

[0002] With the continuous promotion of green hydrogen energy, Stirling engines, as external combustion engines that utilize thermoelectric power generation, are widely used in waste heat power generation scenarios of green hydrogen production. The heating end of the Stirling engine needs to receive an external heat source, and a matching support and positioning structure is required to ensure the installation stability of the heating end. To this end, we propose a new type of positioning and support device for the heating end of the Stirling engine.

[0003] The existing technology still has the following drawbacks in its use: Most existing Stirling engine heat-receiving end positioning and support devices are fixed-size integrated structures that cannot be adapted to different specifications of heat-receiving ends, resulting in poor positioning flexibility. The existing Stirling engine heating end positioning and support device is inadequate because the heating end of the Stirling engine generates high temperatures during operation. The existing support device lacks heat protection and guidance structures, which can easily lead to overall heat loss affecting power generation efficiency. It can also accelerate the aging of the device structure due to high temperatures, shortening the device's service life.

[0004] In view of this, we propose a positioning and support device for the heated end of a Stirling engine to solve the existing problems. Summary of the Invention

[0005] The purpose of this invention is to provide a positioning and support device for the heated end of a Stirling engine, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a positioning and support device for the heated end of a Stirling engine, comprising a clamping plate, a protective cover, a fixing ring and a fixing seat, wherein several brackets are fixedly installed on the left side of the fixing seat; A fixing ring is fixedly installed at the left end of the bracket. The fixing ring has a C-shaped ring structure and is connected to each other by bolts. Several telescopic rods are installed on the left side of the fixing ring, and the telescopic rods are rotatably connected to the fixing ring. A snap-fit ​​plate is installed at the left end of the telescopic rod, and an auxiliary plate is installed on the right side of the snap-fit ​​plate by bolts. The right side of the auxiliary plate is rotatably connected to the telescopic rod. A protective cover is fixedly installed between the fixing ring and the card plate.

[0007] Preferably, a controller is fixedly installed on the left side of the card plate, and the controller is electrically connected to several telescopic rods via wires.

[0008] Preferably, the inner diameter of the snap-fit ​​disc is the same as the outer diameter of the auxiliary disc, and the auxiliary disc has a fixing groove inside, and the snap-fit ​​disc and the auxiliary disc are provided with a snap-fit ​​groove.

[0009] Preferably, a telescopic cylinder is provided inside the protective cover near the left side, and the telescopic cylinder is made of a highly elastic, high-temperature resistant material, and the telescopic cylinder has a pleated structure.

[0010] Preferably, the protective cover has a plurality of vent holes inside, and the inner wall of the protective cover is provided with a reflective film, wherein the inner wall of the reflective film has a mirror surface.

[0011] Preferably, a metal washer is fixedly installed on the right side of the fixing seat, and the fixing seat has several threaded holes inside.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention uses several telescopic rods to connect the clamping plate and the fixing ring, and the position of the clamping plate can be flexibly adjusted by the telescopic rods, thereby realizing the position and angle adjustment of the heating end of the Stirling engine. It can adapt to the installation of heating ends of different specifications, improve the flexibility of device installation and positioning, and meet the usage needs of different scenarios.

[0013] This invention, by setting a reflective film on the inside of the protective cover, can reflect the heat emitted outward from the heated end back to the heated end area, reducing the overall heat loss of the device and improving the thermal energy utilization rate of the Stirling engine. At the same time, the telescopic cylinder and the high-temperature resistant protective cover structure can isolate high temperature, preventing other structures of the device from being affected by high temperature for a long time and aging faster, effectively extending the overall service life of the device.

[0016] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 - Figure 6 As shown, the present invention proposes a positioning and support device for the heated end of a Stirling engine, including a snap-fit ​​plate 1, a protective cover 2, a fixing ring 3 and a fixing seat 4. Several brackets 401 are fixedly installed on the left side of the fixing seat 4. The fixing seat 4 can be fixedly installed in a designated position, thereby providing a fixed base for the entire device. The brackets 401 can fix the fixing seat 4 and the fixing ring 3 to facilitate the further installation of surrounding components through the fixing ring 3. A fixing ring 3 is fixedly installed on the left end of the bracket 401. The fixing ring 3 has a C-shaped ring structure and is connected to each other by bolts. Several telescopic rods 301 are installed on the left side of the fixing ring 3. The telescopic rods 301 are rotatably connected to the fixing ring 3. The C-shaped fixing ring 3 can be snapped on the outside of the end of the heated end. The telescopic rod 301 can adjust its length by extending and retracting, thereby adjusting the distance between the snap-fit ​​plate 1 and the fixing ring 3. With the rotatable connection structure at both ends of the telescopic rod 301, the installation angle and position of the snap-fit ​​plate 1 can be adjusted. A snap-fit ​​plate 1 is installed on the left end of the telescopic rod 301, and an auxiliary plate 104 is installed on the right side of the snap-fit ​​plate 1 by bolts. The right side of the auxiliary plate 104 is rotatably connected to the telescopic rod 301. The snap-fit ​​plate 1 can cooperate with the auxiliary plate 104 to snap and fix the outer edge of the heated end. With the adjustment of the telescopic rod 301, the positioning and clamping of heated ends of different specifications can be realized. A protective cover 2 is fixedly installed between the fixing ring 3 and the clamping plate 1. The protective cover 2 can protect and isolate the outer structure of the heated end, preventing heat from spreading directly to the outside.

[0018] Furthermore, a controller 101 is fixedly installed on the left side of the clamping plate 1, and the controller 101 is electrically connected to several telescopic rods 301 through wires. The controller 101 can simultaneously control the extension and retraction of multiple telescopic rods 301, thereby ensuring that the clamping plate 1 is evenly stressed when clamping the heated end. It can also automatically adjust the positioning position of the heated end according to the installation requirements without manual adjustment, thus improving the convenience of device adjustment.

[0019] Furthermore, the inner diameter of the snap-fit ​​plate 1 is the same as the outer diameter of the auxiliary plate 104, and the auxiliary plate 104 has a fixing groove 103 inside. The snap-fit ​​plate 1 and the auxiliary plate 104 are provided with a snap-fit ​​groove 102. The snap-fit ​​groove 102 can snap and fix the end snap-fit ​​plate of the heated end, and the fixing groove 103 can position and support the body of the heated end to ensure the structural stability of the heated end after installation.

[0020] Furthermore, a telescopic cylinder 201 is provided inside the protective cover 2 near the left side. The telescopic cylinder 201 is made of a highly elastic and high-temperature resistant material. The telescopic cylinder 201 has a pleated structure. The pleated telescopic cylinder 201 can elastically extend and retract in accordance with the length change of the telescopic rod 301 and the position adjustment of the clamping plate 1, so as to always maintain the protective cover 2 to seal the periphery of the heated end and avoid gaps in the protection.

[0021] Furthermore, the protective cover 2 has several exhaust holes 202 inside, and the inner wall of the protective cover 2 is provided with a reflective film 203, and the inner wall of the reflective film 203 is a mirror surface. The exhaust holes 202 can maintain the stability of the air pressure inside the protective cover 2. The mirror structure of the reflective film 203 can reflect the heat radiated outward from the heated end back to the heated end, reduce the heat loss outward, improve the heat energy utilization rate, and at the same time, it can also isolate the high temperature from being conducted outward, and slow down the aging speed of other structures of the device.

[0022] Furthermore, a metal washer 402 is fixedly installed on the right side of the mounting base 4, and several threaded holes are opened inside the mounting base 4. The metal washer 402 can increase the structural friction of the mounting base 4 after installation, ensuring that the mounting base 4 will not easily shift or loosen after installation. With the help of the threaded holes, the mounting base 4 can be easily fixedly installed in the designated position of the Stirling engine.

[0023] Working principle: After the device is assembled, the Stirling engine is fixedly installed between the mounting plate 1 and the auxiliary plate 104, with the heated end of the Stirling engine facing the fixed base 4. The entire device is then fixedly installed at the designated position on the Stirling engine body via the fixed base 4. Subsequently, the controller 101 can control the synchronous extension and retraction of multiple telescopic rods 301. The position and angle of the mounting plate 1 are adjusted in conjunction with the rotation structure at both ends of the telescopic rods 301, thereby adjusting the positioning and installation posture of the heated end to adapt to the installation and positioning requirements of heated ends of different specifications. During operation, the reflective film 203 on the inner side of the protective cover 2 can reflect the heat radiated outward from the heated end back to the heated end area, reducing heat loss and improving the utilization rate of thermal energy. At the same time, the high-temperature resistant protective cover 2 and the telescopic cylinder 201 can isolate the high temperature, preventing the other structures of the device from being affected by the high temperature for a long time and accelerating aging, thus extending the overall service life of the device. The pleated telescopic cylinder 201 can adjust its elastic extension and contraction according to the length change of the telescopic rod 301 and the position of the clamping plate 1, always maintaining the closed protection of the heated end by the protective cover 2 and maintaining a stable protection effect.

[0024] The above specific embodiments are merely several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
