Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings.

Referring to fig. 1, a semi-submersible culvert propeller 10 includes a driver 100 and a rotary paddle 200 disposed on the driver 100, a casing 300 is fixedly disposed on the periphery of the driver 100, a plurality of water inlet grooves 311 are disposed on the outer side wall of the casing 300, a culvert 321 communicated with the water inlet grooves 311 is disposed on one end of the casing 300 close to the rotary paddle 200, and when the driver 100 is used to drive the rotary paddle 200 to rotate, water flows into the casing 300 from the water inlet grooves 311 and flows out of the casing 300 through the culvert 321.

It should be noted that the driver 100 is fixedly installed in the housing 300, wherein the housing 300 is a cavity structure, and the driver 100 is installed in the cavity. The rotary paddle 200 is mounted on an output shaft of the driver 100, and the driver 100 drives the rotary paddle 200 to rotate continuously. In one embodiment, the driver 100 is a motor, and the motor drives the rotary paddle 200 to rotate continuously. In one embodiment, the rotor 200 includes a plurality of blades, such as three blades, each of which is configured in an inclined configuration such that when the rotor 200 rotates, the water flow can generate a counter-thrust on the blades. Further, a plurality of water inlet grooves 311 are formed on the outer side wall of the housing 300, and water flow can enter the cavity of the housing 300 through the water inlet grooves 311. The end of the housing 300 close to the rotor 200 is further opened with a duct 321, and the rotor 200 is located in the duct 321. Thus, when the driver 100 drives the rotary paddle 200 to rotate, under the thrust action of the paddle, the water flow entering the cavity through the water inlet tank 311 is pushed out from the duct 321, wherein the water flow beaten by the paddle 200 cannot be dispersed all around due to the limiting action of the water flow on the inner side wall of the duct 321, and only can flow out through the outlet of the duct 321, so that the water flow can be effectively prevented from being changed into dispersed spray, the thrust of the water flow in the duct 321 on the paddle is ensured to be maintained, and thus, the power of the driver 100 is prevented from being consumed, and the power efficiency is improved; and because rivers filter through the intake antrum 311, consequently can effectively avoid debris such as pasture and water, rubbish to pass through the commentaries on classics oar 200, consequently can effectively avoid the commentaries on classics oar 200 to be convoluteed by debris, and simultaneously, the protection is wrapped up to commentaries on classics oar 200 and driver 100 to shell 300, can effectively avoid driver 100 and commentaries on classics oar 200 to bump and damage.

Referring to fig. 1, in one embodiment, the housing 300 includes a shell 310 and a duct 320, the duct 320 is fixedly connected to one end of the shell 310, each water inlet tank 311 is located on an outer sidewall of the shell 310, and the duct 321 is located in the duct 320.

It should be noted that the housing 300 is formed by combining the housing 310 and the duct 320, thereby facilitating the mounting and fixing of the actuator 100. The inlet channels 311 are respectively located on the outer side walls of the periphery of the shell 310, the culvert 320 is installed on one end of the shell 310, wherein the culvert 320 is in a tubular structure, the inner cavity of the culvert is a culvert 321, and the culvert 321 is communicated with the cavity of the shell 310 and further communicated with the inlet channels 311. When the driver 100 and the paddles 200 are mounted and fixed on the culvert 320, the driver 100 is slid in along the hollow space of the housing 10, so that the housing 310 is fixed in contact with the culvert 320, and the driver 100 is finally located in the hollow space of the housing 310, and the paddles 200 are located at the position of the culvert 321.

Referring to fig. 2, in an embodiment, the housing 300 further includes a fastening assembly 330, the fastening assembly 330 includes a fastening block 331 and a plurality of connecting pieces 332, one end of each connecting piece 332 is fixedly connected to the fastening block 331, and the other end of each connecting piece 332 is fixedly connected to the inner sidewall of the duct 321.

Specifically, the plurality of connecting pieces 332 are fixedly provided at equal intervals on the duct 321 with the axial center of the duct 321 as the center, and each connecting piece 332 is fixedly connected to the fastening block 331 at the axial center position of the duct 321, so that the fastening block 331 is positioned at the axial center position of the duct 321 by each connecting piece 332, and the actuator 100 is mounted on the fastening block 331 so that the axial center of the output shaft of the actuator 100 coincides with the axial center of the duct 321. Thus, when the driver 100 drives the rotary oar 200 to rotate, the rotary oar 200 can rotate at the central position of the duct 321, and the water flow formed by flapping the blades of the rotary oar 200 has the same distance to each direction, so that the thrust direction generated by the propeller is the extending direction of the axis of the duct 321, and the thrust offset can be prevented. In one embodiment, the connecting pieces 332 are four, and the connecting pieces 332 are equally spaced around the fastening block 331. It should be noted that, the fastening block 331 and the connecting pieces 332 in the duct 321 reduce the cross-sectional area of the duct 321, so that when the rotating paddle 200 rotates in water to generate thrust, the water flow pushed by the rotating paddle 200 is left between the connecting pieces 332, and as the flow channel of the water flow is reduced, the blades of the rotating paddle 200 can better generate thrust to the flowing water.

In one embodiment, the driver 100 is fixedly disposed on the fastening block 331. For example, the driver 100 may be locked and fixed to the fastening block 331 using a locking member such as a screw, and thus, sufficient structural strength between the driver 100 and the fastening block 331 can be secured.

The duct 320, the fastening block 331, and the respective connecting pieces 332 are integrally formed, so that sufficient structural strength can be secured therebetween, and the actuator 100 mounted on the fastening block 331 can be reliably fixed. In one embodiment, the culvert pipe 320, the fastening block 331 and the connecting pieces 332 are made of plastic, and are integrally formed by injection molding.

Referring to fig. 3, in one embodiment, an end of the fastening block 331 away from the driver 100 is configured as a tapered structure. It should be noted that, the end of the fastening block 331 away from the driver 100 is a water flow outlet, which is configured in a cone-shaped structure, on one hand, the water flow outlet is facilitated due to the flow line structure, and on the other hand, the culvert 320 can be more beautiful.

Referring to fig. 1, in an embodiment, the water inlet tank 311 is a kidney-shaped tank structure. It should be noted that, the water inlet slot 311 is configured as a strip-shaped waist-shaped slot structure, rather than a common circular hole-shaped structure, which can improve the efficiency of the external water flow entering the cavity of the housing 310.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
