Description

Technical Field

[0001] The utility model relates to the field of electromechanical technology, and in particular to a multi-purpose propulsion motor for UUVs. Background Art

[0002] Unmanned underwater vehicles (UUVs) first appeared in the 1960s. In the early stages of their development, UUVs were mainly used in civil fields such as deep-water exploration, shipwreck salvage, underwater cable laying and maintenance, and later gradually expanded to military activities such as underwater sound source detection, assisting submarines in avoiding mines, and conducting port tactical reconnaissance. In recent years, with the development of underwater platforms, propulsion, navigation and control systems, and sensor technologies, the application of UUVs in underwater reconnaissance, underwater communications, anti-submarine warfare, mine warfare, information warfare, and other fields has achieved unprecedented development.

[0003] According to the different navigation control methods, UUVs can be divided into two categories: one is a cabled UUV, also known as an underwater remotely operated vehicle (ROV); the other is a cable-free UUV, also known as an underwater autonomous unmanned vehicle (AUV). At present, AUV is the fastest-growing, and its overall technology represents the main development direction of UUV.

[0004] Traditional permanent magnet motors are often used in combination with propellers and other components as propellers. However, for different spectrums of UUVs (including ROVs and AUVs), for permanent magnet motors with the same shaft output power, in the UUV spectrum, they can be used as one or more of the main propulsion motors, vertical propulsion motors, and lateral propulsion motors.

[0005] The installation positions of propulsion motors are also different for AUV and ROV. For example, on AUV, the main propulsion motor is usually installed in the stern submerged fairing through the rear end cover flange and the AUV rear end cover; on ROV, the main propulsion motor is usually installed on both sides of the ROV midships in a cantilevered manner.

[0006] Existing propulsion motor products cannot simultaneously meet the installation requirements of different types of vehicles under the UUV spectrum, and when used as vertical propulsion motors or lateral propulsion motors, existing propulsion motors need to be installed in the UUV groove by means of a clamp encircling the surface of the motor casing. The use of a clamp installation method will increase the water retaining area in the radial direction and reduce the open water efficiency of the propeller. Utility Model Content

[0007] In view of this, the utility model designs a UUV multi-purpose propulsion motor, so that the motor installation place of different types of vehicles under the UUV spectrum has a flow-facing structure, thereby improving the open water efficiency of the propeller.

[0013] A flow-incoming component is provided on the dynamic sealing structure and the front end cover, and the flow-incoming component cooperates with the frustum section of the dynamic sealing structure to form a flow-incoming structure.

[0019] On the basis of the above scheme, further, when the propulsion motor is fixed to the ROV midship housing, a propeller and a hub cap are installed on the shaft extension;

[0020] On the outer circumference of the cylindrical section of the dynamic sealing structure, a guide tube B and a hoop B are sequentially sleeved as a flow component.

[0021] The front end of the conduit B is connected to the frustum section, the rear end of the conduit B is butted against the front end of the hoop B, and the rear end of the hoop B is connected to the front end cover.

[0022] The structure formed by the conduit B and the hoop B coincides with the generatrix of the frustum section, so that the conduit B, the hoop B and the dynamic sealing structure form a flow-incoming structure;

[0023] The rear end cover is provided with a hoop A;

[0024] The hoop B and the hoop A fix the propulsion motor on the ROV midship housing.

[0025] On the basis of the above scheme, further, when the propulsion motor is fixed in the UUV channel, a propeller and a hub cap are installed on the shaft extension;
