Description

Technical Field

[0001] The utility model relates to the technical field of thrusters, in particular to a double-blade electric thruster. Background Art

[0002] A thruster is a device that converts any form of energy into mechanical energy. It generates thrust by rotating blades or jetting air (water). It can be used to drive a vehicle forward or as a power source for other devices such as a generator.

[0003] For most existing double-blade electric thrusters, the power component and the external housing are usually fixed by bolts. When the power component fails and needs to be disassembled and repaired later, it takes a lot of time to disassemble and assemble it, resulting in low efficiency of disassembly and repair. Therefore, we propose a double-blade electric thruster. Content of the Utility Model

[0004] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Simplifications or omissions may be made in this part, as well as in the abstract and the title of the application, to avoid obscuring the purpose of this part, the abstract and the title, and such simplifications or omissions shall not be used to limit the scope of the utility model.

[0005] In view of the above and / or problems existing in the existing double-blade electric thrusters, the present utility model is proposed.

[0006] Therefore, the purpose of the present utility model is to provide a double-blade electric thruster. By providing external threads on the outer wall of the cover plate and internal threads on the inner wall of the housing, the housing is threadedly installed on the cover plate. When it is necessary to repair the power component inside the housing, the operator can directly rotate the housing to remove it from the cover plate, exposing the power component inside the housing, thereby facilitating the repair and improving the disassembly and repair efficiency.

[0012] Preferably, a fixing plate is fixed to the outside of the cover plate near the mounting plate end, and mounting bolts are arranged on the fixing plate. The mounting bolts penetrate through the fixing plate and into the mounting plate. Under the action of the fixing plate, the cover plate is mounted on the mounting plate through the mounting bolts. Later, the operator can remove the cover plate from the mounting plate by removing the mounting bolts, which is convenient for disassembly, assembly and replacement of the cover plate.

[0013] Preferably, the mounting bolts penetrate through the entire mounting plate. The mounting bolts penetrating through the entire mounting plate not only mount the cover plate on the mounting plate, but also mount the mounting plate together with the entire electric propulsion assembly at a specified position.

[0027] The present utility model provides a double - blade electric thruster. By providing an external thread on the outer wall of the cover plate and an internal thread on the inner wall of the housing, the housing is threadedly mounted on the cover plate. When it is necessary to repair the power assembly inside the housing, the operator can directly rotate the housing to remove it from the cover plate, exposing the power assembly inside the housing, thereby facilitating the repair of it and improving the disassembly, assembly and repair efficiency.

[0028] Figures 1 - 3 Shown is a schematic structure diagram of an embodiment of a double - blade electric thruster of the present utility model. Please refer to Figures 1 - 3 , A double - blade electric thruster in this embodiment, its main part includes a mounting plate 100 and an electric propulsion assembly 200.

[0029] Mounting plate 100. Preferably, in this embodiment, a protective pad 101 is fixed to the other side of the mounting plate 100. The protective pad 101 is made of rubber. The protective pad 101 fixed on the mounting plate 100 plays a protective role for the mounting plate 100, preventing the mounting plate 100 from being worn. The provided protective pad 101 effectively extends the service life of the mounting plate 100.

[0030] There are two electric propulsion components 200, and the two electric propulsion components 200 are symmetrically arranged on one side of the mounting plate 100. The electric propulsion component 200 includes a cover plate 210 mounted on one side of the mounting plate 100, a motor 220 fixed in the middle of the cover plate 210, a propulsion blade 230 mounted on the output end of the motor 220, and a housing 240 mounted outside the cover plate 210. An external thread 211 is provided on the outer wall of the cover plate 210, and an internal thread 241 is provided on the inner wall of the housing 240. The housing 240 and the cover plate 210 are threadedly connected. Preferably, in this embodiment, a fixing plate 212 is fixed to the outside of the end of the cover plate 210 close to the mounting plate 100. An installation bolt 213 is provided on the fixing plate 212. The installation bolt 213 penetrates through the fixing plate 212 into the mounting plate 100. Under the action of the fixing plate 212, the cover plate 210 is mounted on the mounting plate 100 through the installation bolt 213. In the later stage, the operator can remove the cover plate 210 from the mounting plate 100 by removing the installation bolt 213, which is convenient for disassembling, assembling and replacing the cover plate 210. The installation bolt 213 penetrates through the entire mounting plate 100. The installation bolt 213 penetrating through the entire mounting plate 100 mounts the cover plate 210 on the mounting plate 100 on the one hand, and mounts the mounting plate 100 together with the entire electric propulsion component 200 at a specified position on the other hand. The installation bolt 213 is a wing bolt. The installation bolt 213 being a wing bolt is convenient for the operator to disassemble and assemble it, saving time. A plurality of through holes 214 are provided on the cover plate 210. The plurality of through holes 214 are evenly and equidistantly arranged on the cover plate 210. The through holes 214 evenly and equidistantly arranged on the cover plate 210 reduce the weight of the cover plate 210 and indirectly enhance the propulsion force of the electric propulsion component 200.

[0031] Combined Figures 1 - 3 , a double-blade electric thruster in this embodiment is specifically used as follows: The operator mounts the mounting plate 100 together with the electric propulsion component 200 at a specified position through the installation bolt 213. During actual use, the output end is driven to rotate by the motor 220, and the rotating output end drives the propulsion blade 230 to rotate. The rotating propulsion blade 230 generates a thrust to drive the vehicle forward. When the motor 220 (power component) inside the housing 240 fails and needs to be repaired, the operator can directly rotate the housing 240 to remove it from the cover plate 210, so that the motor 220 (power component) located inside the housing 240 is exposed, thereby facilitating the repair of it and improving its disassembly, assembly and repair efficiency.

[0032] Although the present utility model has been described above with reference to the embodiments, various modifications can be made thereto and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed by the present utility model can be combined with each other in any way, and the exhaustive description of these combinations is not given in this specification only for the sake of saving space and resources.
