Example Embodiment

[0020] Specific embodiment one: combination Figure 7 ~ Figure 10 To illustrate this embodiment, a quasi-flexible squid-like pulse jet thruster of this embodiment includes a silicone funnel 2, a squid-like mantle 3, and a cabin body 4. The squid-like mantle 3 is composed of a plurality of shape memory alloy wires 5, The silicone flexible body 6 is composed of a plurality of ribs 7, and the large diameter end of the silicone funnel 2 is connected to the inner wall of the open end of the cuttlefish mantle 3, and the cabin body 4 is arranged in the cuttlefish mantle 3. The multiple ribs 7 are evenly embedded in the cuttlefish mantle 3 along the circumferential direction of the cuttlefish mantle 3, each rib 7 is arranged along the generatrix direction of the cuttlefish mantle 3, and two adjacent ribs 7 They are connected by a shape memory alloy wire 5, and the shape memory alloy wire 5 is embedded in the cuttlefish mantle 3. See Figure 7 , The cabin 4 is equipped with a control de...

Example Embodiment

[0023] Specific implementation manner two: combination Picture 9 To describe this embodiment, the shape memory alloy wires 5 between two adjacent ribs 7 in this embodiment are arranged in a V shape. With this arrangement, the oblique wire cloth method at a certain angle to the rib 7 increases the length of the SMA wire, thereby increasing the relative movement distance between the two ribs 7. The two ends of the V-shaped arrangement of the shape memory alloy wires 5 are fixed on one rib 7, and the midpoint of the V-shaped arrangement of the shape memory alloy wires 5 is fixed on the other rib 7. The other composition and connection relationship are the same as in the first embodiment.

Example Embodiment

[0024] Specific implementation mode three: combination Figure 7 with Figure 8 To explain this embodiment, the pulse thruster of this embodiment also adds an underwater vector thrust nozzle 1 driven by a shape memory alloy. The underwater vector thrust nozzle 1 driven by the shape memory alloy is fixed on the small diameter end of the silicone funnel 2. on. With this setting, vector propulsion is realized. The shape memory alloy driven underwater vector thrust nozzle 1 adopts the vector thrust nozzle disclosed in the patent number ZL200610010360.5. Other components and connection relationships are the same as those in the first or second embodiment.

Abstract

The invention discloses a quasi-plastic cuttlefish-imitating pulse jet propeller and relates to a cuttlefish-imitating pulse jet propeller. The cuttlefish-imitating pulse jet propeller solves the problems that the existing pulse jet propeller has little thrust, low propelling speed, large noise and poor bionic effect. The large-diameter end of the silica gel hopper (2) is connected with the innerwall of an opened end of a cuttlefish-imitating outer sleeve film (3); the bin body (4) is arranged in the cuttlefish-imitating outer sleeve film (3); a plurality of bars (7) are respectively embeddedin the cuttlefish-imitating outer sleeve film (3) along the peripheral direction of the cuttlefish-imitating outer sleeve film (3); all the bars (7) are respectively arranged along the bus directionof the cuttlefish-imitating outer sleeve film (3); and two adjacent bars (7) are connected by a shape memory alloy wire (5) or the front ends and the rear ends of a plurality of bars (7) are connectedby two shape memory alloy wires (5). The quasi-plastic cuttlefish-imitating pulse jet propeller has little resistance at the outer wall when in propelling, realizes deeper submergence, has simple structure, realizes silent propelling and has fast propelling speed.

Description

technical field [0001] The invention relates to a squid-like pulse jet propeller. Background technique [0002] Most small underwater robots now use propellers driven by electric motors for propulsion. Propeller propulsion has the advantages of small size and easy installation, but it also has disadvantages such as loud noise, cavitation, easy damage to underwater organisms, damage to the underwater environment, and easy entanglement by seaweed. Therefore, propeller propulsion is not suitable for occasions that require quietness, concealment and environmental protection, such as scientific observation, military investigation, and deep-sea exploration. [0003] Researchers have studied the propulsion methods of marine organisms to find viable alternatives. The propulsion methods of aquatic organisms can be divided into three types: wave propulsion (such as fish), pulse jet propulsion (such as squid) and flagella / cilia propulsion (such as paramecium). The first two propulsi...
