Description

Technical Field

[0001] This application relates to the field of ex-situ conservation technology for wildlife, and in particular to enrichment devices for marine mammals. Background Technology

[0002] Enrichment refers to a series of measures taken in artificial conservation environments to enrich the lives of wild animals, meet their physiological and psychological needs, and encourage them to exhibit more natural behaviors.

[0003] In related technologies, by taking into account the habits, diets, and habitats of marine mammals, and starting from human experience, we provide marine mammals with the food or play facilities they need, thereby achieving enrichment for marine mammals living in artificial conservation environments.

[0004] However, providing food to artificially conserved marine mammals is merely a subjective act of providing food, resulting in a monotonous and repetitive feeding process. This does not meet the needs of marine mammals for prolonged foraging and skillful foraging in the wild, nor does it satisfy the daily play and interaction needs of highly intelligent cetaceans. Consequently, the enrichment effect on marine mammals is poor, further impacting the ex-situ conservation of national first-class protected animals such as the Yangtze finless porpoise and the Chinese white dolphin.

[0023] In some embodiments, the dimension of the discharge handle along the first direction is greater than the distance between the third and fourth openings.

[0024] In some embodiments, enrichment devices for marine mammals further include:

[0025] A connecting component, one end of which is connected to at least one of a first pipe assembly and a second pipe assembly;

[0026] In the first state, the other end of the connecting component is connected to an external fixed structure.

[0028] A plurality of first connectors, each first connector including a first end and a second end disposed opposite to each other; the first ends of the plurality of first connectors are all used to connect to a fixed structure, and the first ends of the plurality of first connectors are spaced apart from each other;

In a first state, the food moves through the fourth port along the second pipe assembly to the third port, then to the first port connected to the third port, and finally into the first pipe assembly. Because the angle between the discharge direction and the direction of gravity is between 90° and 180° in the first state, the food cannot actively exit through the second port to the outside of the first pipe assembly. Therefore, the animal needs to push the first pipe assembly to cause it to shake, allowing the food inside to be discharged, thus improving the enrichment effect for the animal.

[0052] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0053] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0054] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0055] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0056] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0057] It should be further clarified that the enrichment device for marine mammals in this application is used for enriching marine mammals. Of course, it is understood that the enrichment device for marine mammals in this application can be installed on land, i.e., it can enrich terrestrial animals; and it can be installed in water, i.e., it can enrich aquatic animals. This application does not limit the species or type of animals. The aquatic animals can be marine animals or freshwater animals, etc., and similarly, there are no restrictions on the species or type of aquatic animals here.

[0058] Exemplarily, this application uses an enrichment device for marine mammals as an example for enriching marine mammals. Specifically, this application uses the Indo-Pacific humpback dolphin as an example of a marine mammal.

[0059] The Indo-Pacific humpback dolphin is a medium-sized toothed whale belonging to the genus *Phallus* in the family Delphinidae. Adults of this species range in length from 2.0 to 2.8 meters and weigh 150 to 230 kilograms. Its prominent, triangular dorsal fin, located near the center, is one of the distinguishing features for individual identification. The pectoral fins are relatively rounded and broad at the base. The caudal fin is shovel-shaped and primarily used for propulsion and steering during swimming. It possesses 125 to 135 teeth. Skin coloration varies depending on region and population, often exhibiting a mottled gray-white hue with dark spots. The type specimen is from Chinese waters. Newborns in Chinese populations are dark gray, fading to a distinctive pinkish-white with age, making them quite visually appealing; some scholars believe this is a result of overheating. The Indo-Pacific humpback dolphin primarily inhabits shallow coastal waters and estuaries, widely distributed in the tropical and temperate coastal waters of the western Pacific and eastern Indian Oceans, and occasionally appears in freshwater, such as the Yangtze, Minjiang, Jiulongjiang, and Pearl Rivers.

[0060] Specifically, in the process of feeding marine mammals such as the Indo-Pacific humpback dolphin, food is simply provided subjectively, without altering their feeding process. This conventional feeding method makes the feeding process too monotonous for these marine mammals, failing to meet their needs for prolonged and skillful foraging in the wild, resulting in poor enrichment effects. Conservationists need to find ways to increase enrichment materials to achieve a more enriching experience for these marine mammals during feeding.

[0061] See Figure 1 As shown. An embodiment of this application provides an enrichment device 1 for marine mammals, including a first pipe assembly 11 and a second pipe assembly 12. The first pipe assembly 11 includes a first port 11a and a second port 11b that are connected; the first port 11a and the second port 11b have different orientations; the second port 11b has a discharge direction. The second pipe assembly 12 includes a third port 12a and a fourth port 12b that are connected; the third port 12a is connected to the first port 11a; the direction of the fourth port 12b to the third port 12a intersects with the direction of the fourth port 12b to the first port 11a; the fourth port 12b is used to place food. The enrichment device 1 for marine mammals includes a first state. In the first state, food moves along the fourth port 12b into the first pipe assembly 11, and the angle between the discharge direction and the direction of gravity is in the range of 90°-180°.

[0062] It should be noted that the discharge direction of the second nozzle 11b is... Figure 1 The X-direction in the equation is the direction of gravity. Figure 1 in the Y direction.

[0063] Both the first pipe assembly 11 and the second pipe assembly 12 are used to transport food. The first port 11a of the first pipe assembly 11 and the third port 12a of the second pipe assembly 12 are connected, and food is placed in the fourth port 12b. Since the direction from the fourth port 12b to the third port 12a intersects the direction from the fourth port 12b to the first port 11a, the second pipe assembly 12 can be tilted relative to the first pipe assembly 11. Therefore, in a first state, food can move along the second pipe assembly 12 through the fourth port 12b to the third port 12a, then to the first port 11a connected to the third port 12a, and finally into the first pipe assembly 11.

[0064] It should be added that, during the actual use of the enrichment device 1 for marine mammals by the operator, the relative position and tilt angle of the first pipe assembly 11 and the second pipe assembly 12 can be reasonably set or adjusted by external force according to the actual needs. As long as the angle between the discharge direction and the gravity direction is within the range of 90°-180° in the first state, it is acceptable.

[0065] Furthermore, in the first state, the angle between the discharge direction and the direction of gravity ranges from 90° to 180°, meaning the first pipe assembly 11 near the second opening 11b forms a bent structure. This prevents food from actively being discharged through the second opening 11b to the outside of the first pipe assembly 11. At this time, animals cannot directly access the food. If an animal wants to access the food in this area, it needs to push the first pipe assembly 11 to cause it to shake, allowing the food inside to fall out or be discharged, thus improving the enrichment effect for the animal.

[0066] Based on the above description, since animals need to push the first pipe assembly 11 to make it shake so that food inside the first pipe assembly 11 can fall out or be discharged in order to obtain food, this can improve the animal's physical adaptability and coordination, and also provide mental exercise for the animal. At the same time, it can increase interaction between animal groups and improve their coordination and cooperation. In addition, this enrichment device 1 for marine mammals can also be used to better train animals, thereby increasing the animals' visibility in public.

[0067] In addition, the animal needs to constantly push the first tube component 11 to get food during the feeding process, which can increase the entertainment value of the animal during the feeding process and thus reduce the animal's stress.

[0068] In some embodiments, see Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the first pipe assembly 11 includes a first pipe 111 and a first adapter 112. One end of the first pipe 111 is configured as a first port 11a; at least a portion of the first pipe 111 is designed for placement in water. The first adapter 112 includes a plurality of interconnected connectors 112a; one of the connectors 112a of the first adapter 112 connects to the end of the first pipe 111 away from the first port 11a; at least one of the remaining connectors 112a of the first adapter 112 is configured as a second port 11b; the first adapter 112 is designed for placement in water.

[0069] Thus, since one end of the first pipe 111 is configured as a first port 11a; at least a portion of the first pipe 111 is used in water, one of the adapter ports 112a of the first adapter 112 connects to the end of the first pipe 111 away from the first port 11a; at least one of the remaining adapter ports 112a of the first adapter 112 is configured as a second port 11b; the first adapter 112 is used in water, so that by connecting and cooperating the first pipe 111 and the first adapter 112, it can be formed to face different first ports 11a and second ports 11b, thereby facilitating the manufacturing process of the first pipe assembly 11.

[0070] Furthermore, since at least one of the remaining adapter ports 112a of the first adapter 112 is configured as a second port 11b, multiple second ports 11b can be provided on the first adapter 112, which can further improve the enrichment effect during animal feeding. At the same time, since at least a portion of the first pipe 111 is designed to be submerged in water, while the second pipe assembly 12 does not need to be submerged, operators can feed aquatic animals without entering the water, facilitating operator convenience.

[0071] In some embodiments, the plurality of adapters 112a include a first adapter 112b, a second adapter 112c, and a third adapter 112d; the first adapter 112b connects to the end of the first pipe 111 away from the first port 11a; the second adapter 112c and the third adapter 112d are both configured as second ports 11b. The angle between the discharge direction of the second adapter 112c and the direction of gravity is 90°, and the angle between the discharge direction of the third adapter 112d and the direction of gravity is 90°.

[0072] Thus, since the angle between the discharge direction of the second adapter 112c and the direction of gravity is 90°, and the angle between the discharge direction of the third adapter 112d and the direction of gravity is 90°, it can be ensured that when food enters the first pipe assembly 11 through the fourth port 12b, food is prevented from being discharged directly through the second adapter 112c or the third adapter 112d.

[0073] Furthermore, since both the second adapter 112c and the third adapter 112d are configured as the second port 11b, food can be discharged through the second adapter 112c or the third adapter 112d while the animal is pushing the first pipe 111, thus making the discharge position of the food uncertain and further improving the enrichment effect of the animal during feeding.

[0074] It should be further explained that, for aquatic animals, the first adapter 112 is located in the water. During the process of the aquatic animals pushing the first pipe 111, the food in the first pipe assembly 11 will be subjected to the combined effects of the impact force and resistance of the water flow, thus providing more uncertainty for the location of the food discharge, which can further improve the enrichment effect of aquatic animals during the feeding process.

[0075] In some embodiments, the second pipe assembly 12 includes a second pipe 121 and a second adapter 122. One end of the second pipe 121 is configured as a fourth port 12b. The second adapter 122 includes a first connecting segment 1221 and a second connecting segment 1222 that are in communication with each other. The end of the first connecting segment 1221 away from the second connecting segment 1222 is in communication with the end of the second pipe 121 away from the fourth port 12b. The end of the first connecting segment 1221 near the second connecting segment 1222 is configured as a third port 12a. The extension direction of the first connecting segment 1221 intersects the extension direction of the second connecting segment 1222, and the extension direction of the second connecting segment 1222 is the same as the extension direction of the first pipe 121.

[0076] Thus, since the second pipe assembly 12 is composed of the second pipe 121 and the second adapter 122, the connection between the second pipe 121 and the first pipe 111 can be achieved through the second adapter 122. Furthermore, since the second adapter 122 includes a first connecting section 1221 and a second connecting section 1222 that are interconnected, and the extension direction of the first connecting section 1221 intersects the extension direction of the second connecting section 1222, and the extension direction of the second connecting section 1222 is the same as the extension direction of the first pipe 111, the extension direction of the first pipe 111 and the extension direction of the second pipe 121 can be different through the second adapter 122, meaning the second pipe 121 is inclined relative to the first pipe 111. This allows the operator to adjust the position and angle of the second pipe 121 and the first pipe 111 according to actual usage needs, facilitating the transfer of food through the fourth port 12b.

[0077] Meanwhile, since the second pipe assembly 12 is formed by connecting and cooperating the second pipe 121 and the second adapter 122, the manufacturing process of the second pipe assembly 12 can be facilitated.

[0078] In some embodiments, the angle between the extending direction of the first connecting segment 1221 and the extending direction of the second connecting segment 1222 is 30°-60°.

[0079] Thus, since the angle between the extension direction of the first connecting segment 1221 and the extension direction of the second connecting segment 1222 is 30°-60°, it avoids the situation where the angle between the extension directions of the first connecting segment 1221 and the second connecting segment 1222 is too small, making it difficult for food to pass through the second pipe assembly 12 into the first pipe assembly 11, thereby affecting the normal food transmission process. At the same time, it avoids the situation where the angle between the extension directions of the first connecting segment 1221 and the second connecting segment 1222 is too large, causing the food to pass through the second pipe assembly 12 into the first pipe assembly 11 at too high a speed, resulting in excessive impact force on the final landing position of the food in the first pipe assembly 11, thus preventing damage to the first pipe assembly 11. Based on the above explanation, since the angle between the extension directions of the first connecting segment 1221 and the second connecting segment 1222 is 30°-60°, the service life of the enrichment device 1 for marine mammals can be improved while ensuring smooth food transmission.

[0080] In some embodiments, see Figure 2 and Figure 3 As shown, the enrichment device 1 for marine mammals also includes a feeding assembly 13. The feeding assembly 13 includes a feeding handle 131 and a feeding head 132; one end of the feeding head 132 is connected to one end of the feeding handle 131; the feeding handle 131 extends along a first direction, and the projection of the feeding handle 131 is located within the projection of the feeding head 132 along the first direction; the feeding head 132 is used to place food, and the feeding handle 131 is used to transfer the food on the feeding head 132 to the fourth port 12b.

[0081] It should be noted that the first direction in this application is... Figure 2 The Z direction in the equation.

[0082] Thus, since the feeding assembly 13 includes a feeding handle 131 and a feeding head 132, the feeding head 132 is used to place food, and the feeding handle 131 is used to transfer the food on the feeding head 132 to the fourth port 12b, the operator can place the food on the feeding head 132 and transfer the food directly to the fourth port 12b through the feeding handle 131 at a convenient feeding location according to the actual feeding process. This makes the feeding point location flexible, which on the one hand can achieve diversification of feeding locations, and on the other hand can facilitate the feeding process for the operator.

[0083] Furthermore, since the projection of the feeding handle 131 is located within the projection of the feeding head 132 along the first direction, that is, the cross-sectional area of ​​the feeding head 132 along the first direction is larger than the cross-sectional area of ​​the feeding handle 131 along the first direction, more food can be placed on the feeding head 132, which facilitates the feeding process for operators.

[0084] It should be noted that the shape of the feeding head 132 can be triangular, circular, elliptical, rectangular, or irregular. When the feeding head 132 is triangular, the feeding component 13 is formed as a structure similar to a "shovel"; when the feeding head 132 is elliptical, the feeding component 13 is formed as a structure similar to a "spoon". This application does not limit or elaborate on the specific shape and structure of the feeding head 132.

[0085] Of course, to facilitate the operation of the operator, the operator can also use local materials. For example, a waste water bottle can be used. Part of the water bottle can be cut off and used as a feeding head 132. The water bottle part is connected to the feeding handle 131. The operator can place the food directly on the surface of the water bottle, thereby transferring the food to the fourth pipe opening 12b, which can facilitate the operation process of the operator.

[0086] In some embodiments, the dimension of the discharge handle 131 along the first direction is greater than the distance between the third port 12a and the fourth port 12b.

[0087] Thus, since the dimension of the discharge handle 131 along the first direction is greater than the distance between the third port 12a and the fourth port 12b, the operator is not limited by the feeding location. On the one hand, the feeding location can be further diversified; on the other hand, the feeding process can be further facilitated.

[0088] In some embodiments, see Figure 6 As shown, the enrichment device 1 for marine mammals also includes a connecting component 14. One end of the connecting component 14 is connected to at least one of the first pipe assembly 11 and the second pipe assembly 12. In a first state, the other end of the connecting component 14 is connected to an external fixing structure 2.

[0089] Thus, in the first state, one end of the connecting component 14 is connected to at least one of the first pipe assembly 11 and the second pipe assembly 12, and the other end of the connecting component 14 is connected to the fixed structure 2, thereby allowing the first pipe assembly 11 and the second pipe assembly 12 to be in a movable state. As a result, when the animal pushes the first pipe assembly 11, the first pipe assembly 11 can sway relative to the fixed structure 2, which can ensure that the food is smoothly discharged during the animal's pushing process.

[0090] In some embodiments, the connecting assembly 14 includes a plurality of first connectors 141 and second connectors 142. Each first connector 141 includes a first end and a second end disposed opposite to each other; the first ends of each plurality of first connectors 141 are all used to connect to the fixing structure 2, and the first ends of the plurality of first connectors 141 are spaced apart. The second ends of each plurality of first connectors 141 are all connected to one end of a second connector 142, and the end of a second connector 142 away from the plurality of first connectors 141 is connected to at least one of a first pipe assembly 11 and a second pipe assembly 12.

[0091] Thus, since the second ends of the multiple first connectors 141 are all connected to one end of the second connector 142, and the end of the second connector 142 away from the multiple first connectors 141 is connected to at least one of the first pipe assembly 11 and the second pipe assembly 12, the connection between the multiple first connectors 141, the second connector 142, and the fixed structure 2 can ensure the stability and reliability of the connection between the second connector 142 and the fixed structure 2, thereby ensuring the overall stability and reliability of the enrichment device 1 for marine mammals. Furthermore, since the second ends of the multiple first connectors 141 are all connected to one end of the second connector 142, the connection between one first connector 141 and at least one of the first pipe assembly 11 and the second pipe assembly 12 can ensure that the first pipe assembly 11 can sway relative to the fixed structure 2 during the process of the animal pushing it, ensuring smooth food discharge during the animal's pushing process.

[0092] Optionally, the second connector 142 has a snap-fit ​​unit at one end near one end of the plurality of first connectors 141, and the second ends of the plurality of first connectors 141 are all connected to the snap-fit ​​unit of the second connector 142. According to actual usage needs, when it is necessary to connect the first connectors 141 and the second connector 142, the operator only needs to snap the second end of the first connector 141 into the snap-fit ​​unit of the second connector 142; when it is not necessary to connect the first connectors 141 and the second connector 142, the operator only needs to detach the second end of the first connector 141 from the snap-fit ​​unit of the second connector 142, thus facilitating the connection process of the first connectors 141 and the second connector 142.

[0093] Furthermore, the snap-fit ​​unit of the second connector 142 can be configured as a collar. When it is necessary to connect the first connector 141 and the second connector 142, it is only necessary to pass the second end of the first connector 141 through the collar of the snap-fit ​​unit, which can further facilitate the operator to connect the first connector 141 and the second connector 142.

[0094] Of course, the first connector 141 and the second connector 142 can also adopt other connection methods. Here, the specific connection methods of the first connector 141 and the second connector 142 will not be limited or described in detail.

[0095] In some embodiments, the first pipe assembly 11 is a one-piece molded structure.

[0096] Thus, because the first pipe assembly 11 is a one-piece molded structure, on the one hand, it eliminates gaps in splicing or welding, resulting in a more continuous and uniform overall structure. This allows it to withstand higher pressures and external forces, reducing the risk of breakage or leakage due to weak connections, and improving the reliability and safety of the first pipe assembly 11. On the other hand, the one-piece molding process is simpler, reducing the need for separate processing, assembly, and connection of multiple components. This significantly shortens the production cycle of the first pipe assembly 11, improves production efficiency, and reduces production costs.

[0097] In some embodiments, the second pipe assembly 12 is a one-piece molded structure.

[0098] Thus, because the second pipe assembly 12 is a one-piece molded structure, on the one hand, it eliminates gaps in splicing or welding, resulting in a more continuous and uniform overall structure. This allows it to withstand higher pressures and external forces, reducing the risk of breakage or leakage due to weak connections, and improving the reliability and safety of the second pipe assembly 12. On the other hand, the one-piece molding process is simpler, reducing the need for separate processing, assembly, and connection of multiple components. This significantly shortens the production cycle of the second pipe assembly 12, improves production efficiency, and reduces production costs.

[0099] In some embodiments, the first pipe assembly 11 and the second pipe assembly 12 are integrally formed.

[0100] Thus, since the first pipe assembly 11 and the second pipe assembly 12 are integrally molded, on the one hand, there are no gaps between the first pipe assembly 11 and the second pipe assembly 12, making the overall structure more continuous and uniform, capable of withstanding higher pressure and external forces, reducing the risk of cracking or leakage due to weak connection points, and improving the reliability and safety of the first pipe assembly 11 and the second pipe assembly 12. On the other hand, the integral molding manufacturing process is simpler, reducing the steps of processing, assembling, and connecting multiple parts separately, which can greatly shorten the production cycle between the first pipe assembly 11 and the second pipe assembly 12, improve production efficiency, and reduce production costs.

[0101] Optionally, the first pipe assembly 11 can be formed by adhesive bonding, and the second pipe assembly 12 can also be formed by adhesive bonding. The first pipe assembly 11 and the second pipe assembly 12 can also be formed by adhesive bonding. Here, the specific connection methods of the first pipe assembly 11 and the second pipe assembly 12 are defined and described in detail.

[0102] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0103] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
