Description

Technical Field

[0001] This utility model relates to the field of boat technology, and in particular to an installation and fixing device, and an all-terrain boat power system using the installation and fixing device. Background Technology

[0002] An all-terrain vehicle is a vehicle equipped with a power system and a steering system, capable of operating in various environments where conventional vehicles and boats cannot, such as water, snow, ice, desert, and swamp, utilizing aerodynamic principles. The power system of an all-terrain vehicle includes an engine and a propeller. The engine shaft is axially connected to the propeller, thus driving the propeller to propel the all-terrain vehicle.

[0003] Currently, all-terrain vessels are equipped with a separate engine room, with the engine located inside and fixed to the hull structure via an engine mount. This engine arrangement occupies a large amount of hull space and affects the overall layout. In addition, the propeller is housed in a fairing frame. While the propeller is axially fixed to the engine shaft, the fairing frame is also connected and fixed to the hull structure to ensure the reliability of the propeller's fixation. However, the presence of the fairing frame makes it difficult to disassemble and assemble the propeller, affecting the disassembly and assembly of the propeller during transportation and daily maintenance. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an installation and fixing device and an all-terrain boat power system that occupy little space and facilitates the disassembly and maintenance of the propeller.

[0005] The present invention adopts the following technical solution:

[0006] This utility model provides an installation and fixing device, including an engine frame and a propeller mounting bracket. The engine frame has an installation space inside for storing the engine, and an engine accommodating opening outside the engine frame that connects to the installation space. The engine frame is fixedly connected to the hull structure of the all-terrain vessel. The propeller mounting bracket has an installation slot for mounting the propeller, and the propeller mounting bracket is detachably connected to the engine frame.

[0007] Preferably, the engine frame is provided with mounting lugs within the mounting space for mounting and securing the engine.

[0008] Preferably, the engine frame is a rectangular frame structure, and the top surface and one side surface of the engine frame are provided with engine accommodating openings.

[0009] Preferably, connecting sleeves are fixed at the four corners of the bottom of the engine frame, and the four connecting sleeves are fitted and fixed to the hull structure of the all-terrain vessel.

[0010] Preferably, the bottom of the propeller mounting bracket is provided with a connecting base, and the propeller mounting bracket is threadedly connected to the engine frame through the connecting base.

[0011] Preferably, the propeller mounting bracket has multiple mounting slots, and the mounting space of the engine frame can accommodate an engine of equal size to the mounting slots.

[0012] This utility model also provides an all-terrain boat power system, including an engine, a propeller, and a mounting and fixing device for any of the above. The engine is installed in the mounting space of the engine frame, the propeller is rotatably mounted on the propeller base, the propeller base is located in the mounting groove of the propeller mounting bracket, and the engine shaft is drivenly connected to the propeller.

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

[0014] In use, the mounting and fixing device of this utility model allows the engine to be placed in the installation space through the engine accommodating port on the engine frame. The engine frame provides fixation and protection for the engine, eliminating the need for a dedicated engine room. Compared to the traditional method of setting up an engine base in the engine room, this effectively reduces the installation weight and space required for the engine. The propeller is directly mounted on the propeller mounting bracket through the mounting slot, eliminating the need for the traditional fairing frame. This shortens the propeller assembly and disassembly time and improves the maintenance and installation efficiency of the propeller. In addition, the engine frame and propeller mounting bracket adopt a combined installation structure design, which not only facilitates the transmission connection between the engine and propeller but also makes the power system layout more compact, saving ship space.

[0015] The all-terrain vehicle power system of this utility model naturally possesses the aforementioned beneficial effects due to the use of the above-mentioned installation and fixing device. Furthermore, since the propeller is mounted on the propeller mounting bracket via a propeller base, it not only ensures the rotation of the propeller but also shares the vibration of the propeller through the propeller mounting bracket, thereby improving the installation stability of the propeller and ensuring the high-speed navigation of the all-terrain vehicle.

[0029] See Figures 1 to 4This embodiment provides an installation and fixing device, including an engine frame 1 and a propeller mounting bracket 2. The engine frame 1 has an installation space 101 for storing the engine inside, and an engine accommodating opening 102 communicating with the installation space 101 on the outside of the engine frame 1. The engine frame 1 is fixedly connected to the hull structure of the all-terrain vessel. The propeller mounting bracket 2 has an installation slot 201 for mounting the propeller, and the propeller mounting bracket 2 is detachably connected to the engine frame 1.

[0030] In this embodiment, the engine can be stored in the installation space 101 through the engine accommodating port 102 on the engine frame 1. The engine frame 1 provides fixation and protection for the engine, eliminating the need for a dedicated engine room. Compared to the traditional method of setting up an engine base in the engine room, this effectively reduces the installation weight and space required for the engine. The propeller is directly mounted on the propeller mounting bracket 2 through the mounting slot 201, eliminating the need for the traditional fairing frame. This shortens the propeller assembly and disassembly time and improves the maintenance and installation efficiency of the propeller. In addition, the engine frame 1 and the propeller mounting bracket 2 adopt a combined installation structure design, which not only facilitates the transmission connection between the engine and the propeller but also makes the power system layout more compact and saves ship space.

[0031] Preferably, see Figure 1 The engine frame 1 has a mounting lug 103 within the mounting space 101 for mounting and securing the engine. In actual use, the engine is connected and secured to the mounting lug 103 by threaded fasteners.

[0032] Preferably, see Figure 3 The engine frame 1 is a rectangular frame structure, and the top surface and one side surface of the engine frame 1 are provided with engine receiving openings 102 to facilitate the installation and fixing of the engine.

[0033] Preferably, see Figure 1 and Figure 3 Connecting sleeves 104 are fixed at the four corners of the bottom of the engine frame 1, and the four connecting sleeves 104 are fitted and fixed to the hull structure of the all-terrain vessel.

[0034] Preferably, see Figure 1 and Figure 4 The propeller mounting bracket 2 has a connecting base 202 at its bottom, and the propeller mounting bracket 2 is threadedly connected to the engine frame 1 through the connecting base 202.

[0035] Preferably, the propeller mounting bracket 2 has multiple mounting slots 201, and the mounting space 101 of the engine frame 1 can accommodate an engine of the same size as the mounting slots 201.

[0036] It should be noted that since each mounting slot 201 can install one propeller, the setting of multiple mounting slots 201 means the existence of multiple propellers. Therefore, the mounting space 101 also needs to be able to set an equal number of engines so that the engines and propellers are connected in a one-to-one transmission.

[0037] This embodiment also provides an all-terrain boat power system, including an engine, a propeller and the aforementioned mounting and fixing device. The engine is installed in the mounting space 101 of the engine frame 1, the propeller is rotatably mounted on the propeller base, the propeller base is located in the mounting groove 201 of the propeller mounting bracket 2, and the engine shaft is connected to the propeller drive.

[0038] The all-terrain vehicle power system of this embodiment naturally possesses the aforementioned advantages due to the use of the above-mentioned mounting and fixing device. Since the propeller is mounted on the propeller mounting bracket 2 via the propeller base, the propeller vibration can be shared by the propeller mounting bracket 2 while ensuring propeller rotation, thereby improving the installation stability of the propeller and ensuring the high-speed navigation of the all-terrain vehicle.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
