Description

Technical Field

[0001] This utility model relates to the field of support structure technology, specifically a support structure for the cooling pipe of a range-extended marine hybrid engine. Background Technology

[0002] Range-extended marine hybrid power systems typically include an internal combustion engine (range extender), a generator, an electric motor, a power battery pack, and a complex cooling system. The cooling piping is responsible for thermal management of the engine, power electronic equipment (such as inverters and rectifiers), and the battery pack, and its stability and reliability are of paramount importance.

[0003] For example, patent publication number "CN220337634U", entitled "A Ship Refrigeration Pipe Support", includes an angle steel. A support column is fixedly connected to the middle of the top of the angle steel. A connecting seat is fixedly connected to the top of the support column. The connecting seat has a groove in the middle of its front end. A cover plate is fixedly connected to the middle of the front end of the connecting seat. The cover plate is used in conjunction with the groove. A spring is fixedly connected to the bottom of the groove. The top of the spring has a limiting structure. Through holes are opened on the upper parts of both sides of the connecting seat. The advantages of the above patent and existing technologies are: small size, low cost, easy replacement; adaptable to different specifications of refrigeration pipes; convenient for refrigeration pipe insulation cotton construction; effectively avoids refrigeration pipe wear problems, and is convenient and quick.

[0004] Because the water flow inside the cooling pipe causes vibration when it passes through, the vibration reduction structure of the above-mentioned patent is relatively simple and mainly relies on a single spring for vertical buffering. For the multi-directional and complex vibration generated by the cooling pipe, the internal moving parts wear down due to insufficient guidance, resulting in a reduction in the service life of the cooling pipe. Therefore, a cooling pipe support structure for range-extended marine hybrid engines is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a cooling pipe support structure for a range-extended marine hybrid engine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a range-extended marine hybrid engine cooling pipe support structure, including a base plate, a support column fixedly connected to the top of the base plate, a buffer assembly fixedly connected to the top of the support column, and a clamping assembly for clamping the cooling pipe installed at the top of the buffer assembly.

[0007] The buffer assembly includes a fixed frame, the bottom end of which is fixed to the top end of a support column. A movable plate is slidably connected inside the fixed frame. A first spring damper is fixedly connected to one side of the movable plate. A limiting plate is fixedly connected to the telescopic end of the first spring damper. A second spring damper is fixedly connected to the top end of the limiting plate. A sliding frame is fixedly connected to the telescopic end of the second spring damper. The top end of the sliding frame is fixed to the bottom end of a clamping assembly.

[0008] Preferably, the clamping assembly includes a bottom ring member, the bottom end of which is slidably connected to the top end of the sliding frame, and a top ring member is mounted on the top end of the bottom ring member via a connecting device.

[0009] Preferably, the connecting device includes a first bolt, the bottom end of which passes through the top ring and the bottom ring in sequence and is threaded to the inner wall of the first nut.

[0010] Preferably, the inner wall of the sliding frame and the outer wall of the limiting plate are slidably connected, and through holes are provided on both sides of the top ring, through which the bottom end of the No. 1 bolt passes through the through holes to penetrate the top ring.

[0011] Preferably, the bottom end of the limiting plate is fixedly connected to a caster wheel, and the bottom end of the caster wheel is in contact with the bottom end inside the fixing frame.

[0012] Preferably, the inner wall of the fixed frame is provided with a sliding groove, and one side of the movable plate is slidably connected to the inner wall of the fixed frame through the sliding groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The cooling pipe support structure of this range-extended marine hybrid engine securely clamps the cooling pipe through a clamping assembly, effectively absorbs vibration through a buffer assembly, mitigates vertical vibration through a second spring damper, and allows the extension and retraction of the first spring damper to extend and retract due to changes in the distance between the sliding frame and the limiting plate, thus achieving planar vibration reduction, reducing wear on the cooling pipe, and ensuring the stability and reliability of the cooling system.

[0015] Meanwhile, the clamping assembly, through the combination of the bottom ring and the top ring, can reliably clamp and fix the cooling pipe, and the connecting device facilitates installation and disassembly. The sliding connection between the sliding frame and the limiting plate, the cooperation between the moving plate and the inner wall of the fixed frame, and the setting of the casters together ensure the smoothness and stability of the component movement during the buffering process, avoiding stress concentration or component jamming caused by rigid constraints.

[0020] 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.

[0021] like Figure 1 - Figure 3 As shown, this utility model provides a technical solution: a range-extended marine hybrid engine cooling pipe support structure, including a base plate 1, a support column 2 fixedly connected to the top of the base plate 1, a buffer assembly 3 fixedly connected to the top of the support column 2, and a clamping assembly 4 for clamping the cooling pipe installed at the top of the buffer assembly 3.

[0022] The buffer assembly 3 includes a fixed frame 301, the bottom end of which is fixed to the top end of the support column 2. A movable plate 302 is slidably connected inside the fixed frame 301. A first spring damper 303 is fixedly connected to one side of the movable plate 302. A limiting plate 304 is fixedly connected to the telescopic end of the first spring damper 303. A second spring damper 305 is fixedly connected to the top end of the limiting plate 304. A sliding frame 306 is fixedly connected to the telescopic end of the second spring damper 305. The top end of the sliding frame 306 is fixed to the bottom end of the clamping assembly 4.

[0023] The clamping assembly 4 includes a bottom ring 401, the bottom end of which is slidably connected to the top end of the sliding frame 306, and a top ring 402 is mounted on the top end of the bottom ring 401 via a connecting device.

[0024] The connecting device includes a No. 1 bolt, the bottom end of which passes through the top ring 402 and the bottom ring 401 in sequence and is threaded to the inner wall of the No. 1 nut.

[0025] The inner wall of the sliding frame 306 and the outer wall of the limiting plate 304 are slidably connected. The top ring 402 has through holes on both sides, and the bottom end of the No. 1 bolt passes through the through holes to penetrate the top ring 402.

[0026] A caster wheel is fixedly connected to the bottom end of the limiting plate 304, and the bottom end of the caster wheel is in contact with the bottom end inside the fixing frame 301.

[0027] The inner wall of the fixed frame 301 is provided with a sliding groove, and one side of the movable plate 302 is slidably connected to the inner wall of the fixed frame 301 through the sliding groove.

[0028] The clamping component 4 is used to clamp and fix the position of the cooling pipe. During the cooling pipe transportation process, water flows through the cooling pipe. The flow of water during the cooling process will cause the cooling pipe to vibrate. The buffer component 3 is used to detect the connection between the fixing frame 301 and the clamping component 4. The buffer component 3 can avoid the wear of the cooling pipe caused by the clamping component 4 under vibration, thereby ensuring the service life of the cooling pipe.

[0029] The cooling pipe is placed in the groove on the bottom ring 401, and then the top ring 402 is installed. The bottom ring 401 and top ring 402 are installed using bolt and nut No. 1, thus clamping and restricting the position of the cooling pipe. During use, the vibration generated by the water flow is transmitted to the clamping assembly 4. The second spring damper 305 can buffer the vertical vibration. The distance between the sliding frame 306 and the limiting plate 304 changes, and simultaneously the distance between the limiting plate 304 and the fixed frame 301 changes, causing the extension end of the first spring damper 303 to change, thereby achieving vibration reduction on the plane. Through the cooperation between the first spring damper 303 and the second spring damper 305, spatial vibration reduction is achieved. During vibration reduction, the relative position between the moving plate 302 and the fixed frame 301 changes. The arrangement of the moving plate 302 and the fixed frame 301 facilitates the movement of the first spring damper. The installation of 303 enables the first spring damper 303 to achieve planar vibration reduction. The bottom end of the caster wheel contacts the bottom end inside the fixed frame 301, facilitating the movement of the limiting plate 304 within the fixed frame 301. The cooling pipe is securely clamped by the clamping assembly 4, and the buffer assembly 3 effectively absorbs vibration. The second spring damper 305 mitigates vertical vibration. The change in the distance between the sliding frame 306 and the limiting plate 304 allows the telescopic end of the first spring damper 303 to extend and retract, achieving planar vibration reduction. Reduced wear on cooling pipes ensures the stability and reliability of the cooling system. The clamping assembly 4, through the combination of the bottom ring 401 and the top ring 402, can reliably clamp and fix the cooling pipes. The connecting device facilitates installation and disassembly. The sliding connection between the sliding frame 306 and the limiting plate 304, the cooperation between the moving plate 302 and the inner wall groove of the fixed frame 301, and the setting of the casters together ensure the smoothness and stability of the component movement during the buffering process, avoiding stress concentration or component jamming caused by rigid constraints.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
