Technical Field

[0001] The utility model belongs to the technical field of water rescue equipment and relates to a water rescue flying wing. Background Art

[0002] The water rescue flying wing, also known as the intelligent power lifebuoy, is a lifebuoy with a power system. The rescue flying wing is controlled by a remote control device to sail to the vicinity of the person who falls into the water. The person who falls into the water can float on the water surface through the buoyancy of the rescue flying wing, and the rescue flying wing can be remotely controlled to bring the person who falls into the water back to a safe place.

[0003] The current water rescue flying wing takes in water through the bottom, and then sprays water out from the tail through the impeller to propel itself to move. In rivers with relatively complex environments, there may be debris such as aquatic plants, mud and domestic garbage. A filter is installed at the water inlet of the impeller, but some long strips of aquatic plants or other debris may enter the impeller through the filter and wrap around the impeller, affecting the normal rotation of the impeller. Utility Model Content

[0004] In view of the above problems, the present invention proposes a water rescue flying wing, which effectively solves the problems in the prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0006] A water rescue flying wing, comprising:

[0007] The body comprises a shell, a driver is installed in the shell, and an impeller is rotatably installed at the tail of the shell;

[0008] The filter screen is circular and is installed below the tail of the shell;

[0009] A gearbox, wherein the gearbox is fixedly installed in the housing, the output end of the driver is fixedly connected to the input end of the gearbox, the gearbox is provided with two output ends, and the impeller is connected to the first output end of the gearbox;

[0010] A dividing blade is rotatably mounted on the housing at the filter screen position, and the dividing blade is fixedly connected to the second output end of the gear box.

[0012] Optionally, two filters and dividing blades are provided at the rear of the shell in a mirror-symmetrical manner, and both dividing blades are fixedly connected to the gear box.

[0013] Optionally, the filter is bolted to the housing, the dividing blade is plugged into the output end of the gear box, and the dividing blade is key-connected to the output end of the gear box.

[0014] Optionally, a water outlet net is fixedly mounted at the rear end of the shell, the first output end of the gear box is rotatably pressed against the center of the water outlet net, and a bearing is provided between the first output end of the gear box and the water outlet net.

[0015] Optionally, the impeller includes a shuttle-shaped shaft, a plurality of blades are arranged on the outer circumference of the shuttle-shaped shaft, and the first output end of the gearbox is fixedly connected to the shuttle-shaped shaft.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting the filter and the dividing blade, the filter can filter out larger debris. When strip-shaped debris is sucked into the filter, the rotating dividing blade will crush the debris, reducing the possibility of it being entangled in the impeller and affecting the rotation of the impeller;

[0018] 2. During the cutting process, the object being cut will exert a tangential reaction force on the cutting blade. By setting the cutting blade away from the gearbox and connected to the middle of the filter, the radial support of the cutting blade is increased, and the possibility of the drive shaft bending during the cutting process is reduced.

[0019] 3. By arranging the first output end of the gear box to rotatably abut against the center of the water outlet network, the water outlet network supports the drive shaft of the impeller, reducing the number of supporting parts between the gear box and the water outlet network, further reducing the obstruction to the incoming debris, and the possibility that the debris will remain in the shell and affect the rotation of the impeller.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1 and Figure 2 , which is a water rescue flying wing disclosed in an embodiment of the utility model, includes a main body 1, the main body 1 includes a shell 11, a driver is installed in the shell 11, an impeller 12 is rotatably installed at the tail of the shell 11, a filter screen 2 is installed below the tail of the shell 11, the filter screen 2 is circular, a gear box 3 is fixedly installed in the shell 11, the output end of the driver is fixedly connected to the input end of the gear box 3, the gear box 3 is provided with two output ends, the impeller 12 is connected to the first output end of the gear box 3, the shell 11 is rotatably installed on the dividing blade 4 at the position of the filter screen 2, and the dividing blade 4 is fixedly connected to the second output end of the gear box 3.

[0029] Specifically, a circular filter screen 2 is installed at the water inlet position of the housing 11, and a dividing blade 4 is provided at the filter screen 2 position. The dividing blade 4 is connected to the driver driving the impeller 12 through the gear box 3. When the impeller 12 rotates, the dividing blade 4 rotates accordingly.

[0030] In this way, by setting the filter screen 2 and the dividing blade 4, the filter screen 2 filters larger debris. When strip-shaped debris is sucked into the filter screen 2, the rotating dividing blade 4 breaks the debris into pieces, reducing the possibility of the debris being entangled in the impeller 12 and affecting the rotation of the impeller 12.

[0031] In some feasible embodiments, the main body 1 is partly based on prior art and will not be described in detail here. The gearbox 3 includes a rectangular housing, in which a driving bevel gear is installed. The driving bevel gear is connected to the output shaft of the driver. The output shaft of the driver passes through the rectangular housing and is connected to the impeller 12. The driving bevel gear is meshed with a driven bevel gear. The driven bevel gear is installed on the side of the housing near the filter 2. The driven bevel gear is connected to the dividing blade 4 via a shaft. The dividing blade 4 is used to cut debris entering the filter 2. The rectangular housing is fixedly connected to the housing 11 by bolts, and the filter 2 is set to a circular shape that rotates in conjunction with the dividing blade 4, so that all debris entering the filter 2 passes through the dividing blade 4.

[0032] In some feasible embodiments, the tail of the shell 11 is mostly cylindrical, the filter screen 2 is a circular screen with an arc in the diameter direction, and the blade of the dividing blade 4 can also be set to a shape with an arc in the diameter direction of the rotating surface, so as to be closer to the filter screen 2 and cut the incoming debris.

[0033] As a specific embodiment of a water rescue flying wing provided in the application, a support tube is fixedly installed in the middle of the filter screen 2, and a support column is fixedly provided at one end of the dividing blade 4 away from the gear box 3, and the support column is rotatably installed on the support tube.

[0034] Generally speaking, during the cutting process of the dividing blade 4, the object being cut will give the dividing blade 4 a tangential reaction force. By setting the dividing blade 4 away from the end of the gear box 3 and connected to the middle of the filter screen 2, the radial support of the dividing blade 4 is increased and the possibility of the transmission shaft bending during the cutting process of the dividing blade 4 is reduced.

[0035] Furthermore, two filter screens 2 and dividing blades 4 are provided at the rear of the housing 11 in a mirror-symmetrical manner, and both dividing blades 4 are fixedly connected to the gear box 3 .

[0036] It should be understood that the rescue wing may be flipped over by wind and waves when operating in water. By providing two filters 2 and a dividing blade 4, that is, providing water inlets on both sides of the rear end of the housing 11, the rescue wing can still operate even if it is flipped over by wind and waves. At the same time, the gear box 3 is supported at both ends by support tubes and support columns, which facilitates the formation of a more stable support for the gear box 3.

[0037] In some feasible methods, the filter 2 is bolted to the housing 11, the dividing blade 4 is plugged into the output end of the gear box 3, and the dividing blade 4 is key-connected to the output end of the gear box 3. By setting a detachable filter 2 and dividing blade 4, they can be cleaned and maintained.

[0038] As another specific embodiment of a water rescue flying wing provided in the application, a water outlet net 5 is fixedly installed at the rear end of the shell 11, the first output end of the gear box 3 can be rotatably pressed against the center of the water outlet net 5, and a bearing is provided between the first output end of the gear box 3 and the water outlet net 5.

[0039] In combination with specific usage scenarios, by setting the first output end of the gear box 3 to rotatably abut the center of the water outlet network 5, the water outlet network 5 supports the drive shaft of the impeller 12, reducing the number of support parts between the gear box 3 and the water outlet network 5, and further reducing the obstruction to the incoming debris, so that the debris remains in the shell 11 and may affect the rotation of the impeller 12.

[0040] Furthermore, the impeller 12 includes a shuttle-shaped shaft 121 , and a plurality of blades are arranged on the outer circumference of the shuttle-shaped shaft 121 . The first output end of the gear box 3 is fixedly connected to the shuttle-shaped shaft 121 .

[0041] It should be understood that by providing the shuttle-shaped shaft 121 , the two ends of the middle portion of the impeller 12 are made into a cone shape, which further reduces the possibility of obstruction to the discharge of the incoming debris.

[0042] In some feasible embodiments, the outlet network 5 includes a connecting ring 51, which is bolted or threaded to the rear end of the housing 11. A plurality of radially arranged support bars 52 are mounted in a circumferential array on the inner side of the connecting ring 51. A plurality of concentric rings 53 are disposed on the inner side of the connecting ring 51. The concentric rings 53 and the support bars 52 together form the mesh surface of the outlet network 5. Gaps are provided between the concentric rings 53 near the sidewalls of the housing 11 and the sidewalls. As the impeller 12 rotates, the water flow follows the rotation. Due to its high density, sediment is mostly located on the inner sidewalls of the housing 11. The gaps between the concentric rings 53 and the sidewalls facilitate the discharge of sediment.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
