Description

Technical Field

[0001] The utility model belongs to the technical field of underwater jettisoning, and specifically relates to an improvement in the structure of an electromagnetic jettisoning device. Background Art

[0002] An underwater vehicle is a new type of marine monitoring device that is self-powered, self-propelled, and self-controlled, with the ability to operate underwater and sense the environment. It can operate independently away from the mother ship and has broad application prospects in military and civilian marine development. The jettisoning device is an important part of the underwater vehicle. Its main function is to jettison a certain weight of payload when the underwater vehicle encounters an emergency or malfunctions during underwater operations, thereby reducing the weight of the underwater vehicle itself and achieving an emergency ascent.

[0003] Currently, the most commonly used structure of the jettisoning device for underwater vehicles at home and abroad is mainly the electromagnetic adsorption type.

[0004] The electromagnetic adsorption type structure directly uses an electromagnet to adsorb the payload. Before jettisoning, the electromagnet is energized to adsorb the payload, and jettisoning can be achieved after power-off. However, continuous power supply is required, and the suction force of the electromagnet needs to increase with the increase in the weight of the payload, and the power also increases accordingly. When using a heavier payload, the energy consumption is relatively high.

[0005] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model

[0006] In view of the above technical problems existing in the electromagnetic jettisoning device in the prior art, the utility model proposes a new type of electromagnetic jettisoning device, which realizes a force reduction setting by adding a lever module.

[0007] To achieve the above utility model / design purpose, the utility model adopts the following technical solutions:

[0008] An electromagnetic jettisoning device, comprising:

[0009] A jettisoning base;

[0010] A lever module, comprising:

[0011] A force reduction lever, with hinge ends formed at both ends thereof, and the hinge ends are hinged to the jettisoning base;

[0012] An adsorption end, where an adsorption component is provided;

[0013] A hooking part, formed on the force reduction lever, located between the hinge end and the adsorption end and close to the hinge end, for hanging the payload;

[0014] An electromagnetic sealing module, including a magnetic conductive matrix, is assembled on the throwing matrix;

[0015] An electromagnetic adsorbing member is arranged inside the magnetic conductive matrix and can be switched between energized and de-energized states to separate from or engage with an adsorbing component.

[0016] Compared with the prior art, the advantages and positive effects of the present utility model are:

[0017] In the present utility model, a force-reducing lever is hinged on the throwing matrix, and an adsorbing component is arranged at the end position of the force-reducing lever to cooperate with the electromagnetic adsorbing member. The hook portion is connected to the carried object, and the weight on the carried object is transferred to the force-reducing lever. The force-reducing lever is used for bearing. According to the relationship between the force arm and the force, the acting force transmitted to the adsorbing component is greatly reduced, so that the acting force that the electromagnetic adsorbing member needs to bear for adsorption becomes smaller, and only a smaller power demand for the electromagnetic adsorbing member is correspondingly reduced, thereby reducing the energy consumption and the overall production and manufacturing cost.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

For example, it can be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. In the description of the embodiments, specific features, structures, materials, or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0030] The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0031] In some embodiments of the present application, an electromagnetic throwing device is proposed, including:

[0032] The jettisoning base 100 is used to form a supporting frame of the entire electromagnetic jettisoning device.

[0033] Lever module, used to achieve force reduction, including:

[0034] The force reducing lever 200 has hinged ends 210 formed at both ends thereof, and the hinged ends 210 are hingedly connected to the load-releasing base 100;

[0035] The adsorption end 220 is provided with an adsorption component 300;

[0036] The adsorption component 300 is a adsorption disk 310 .

[0037] The force reduction lever 200 is hinged to the jettisoning base 100 via a hinged end 210 , so that the force reduction lever 200 can rotate relative to the jettisoning base 100 to change its position.

[0038] If the force reducing lever 200 is not provided, the existing adsorption method is to directly adsorb to the load through the electromagnet, and the weight of the load is completely transferred to the electromagnet, and the load is carried by the adsorption force of the electromagnet. At this time, the power required by the electromagnet will be relatively large to ensure the adsorption of the load, which is costly.

[0039] By rotating the force reducing lever 200 connected to the dumping base 100, the weight of the carried object can be carried to reduce the force transmitted to the adsorption end 220, thereby achieving a force reducing effect.

[0040] The hook portion 230 is formed on the force reducing lever 200 .

[0041] The hook portion 230 formed on the force reducing lever 200 can realize the mounting connection with the carried object.

[0042] After the hook portion 230 is connected to the load, the gravity of the load can be transmitted to the force reducing lever 200 .

[0043] In some embodiments, the hook portion 230 is disposed between the hinge end 210 and the suction end 220 and close to the hinge end 210 .

[0044] According to the force analysis based on the knowledge of mechanics, it can be known that: by setting the hook part 230 close to the hinge end 210, the weight of the load can be mainly transferred to the hinge end 210, and the load can be carried by the throwing base 100 to minimize the force transmitted to the adsorption component 300, so as to reduce the force required to adsorb the adsorption component 300.

[0045] The electromagnetic sealing module 400 includes a magnetic conductive base body 410, which is assembled on the throwing base body 100;

[0046] The magnetic conductive base body 410 serves as the base shell of the entire electromagnetic sealing module 400.

[0047] The electromagnetic adsorption member 420 is arranged inside the magnetic conductive base body and can be switched between on and off to separate from or attract the adsorption member 300.

[0048] In some embodiments, the adsorption member 300 is an iron adsorption disc 310 or a magnetic adsorption disc 310, which can be used to attract and fix the electromagnetic adsorption member 420.

[0049] When no throwing is carried out, the electromagnetic adsorption member 420 can attract and fix the adsorption member 300 by adsorbing on it, and at the same time attract and fix the force-reducing lever 200 connected to the adsorption member 300 and the payload mounted on the force-reducing lever 200.

[0050] When the payload needs to be discarded, the electromagnetic adsorption member 420 can be separated from the adsorption member 300. After the adsorption member 300 is separated from the electromagnetic adsorption member 420, under the pulling action of the weight of the payload, the force-reducing lever 200 will drive the adsorption member 300 to rotate downward along the throwing base body 100 to separate from the payload mounted above it, and finally the payload will automatically fall under its own gravity to achieve the deployment of the payload.

[0051] The separation or attraction of the electromagnetic adsorption member 420 and the adsorption member 300 can be achieved by the conversion of power on or off, which is convenient for operation.

[0052] In the embodiments of the present application, the force-reducing lever 200 is hinged on the throwing base body 100 and the adsorption member 300 is arranged at the end position of the force-reducing lever 200 to cooperate with the electromagnetic adsorption member 420. The hook portion 230 is connected to the payload, and the weight on the payload is transferred to the force-reducing lever 200. The force transmitted to the force-reducing lever 200 is greatly reduced after being calculated and distributed by the lever arm, so that the acting force that the electromagnetic adsorption member 420 needs to bear for adsorption becomes smaller, and only a smaller power demand for the electromagnetic adsorption member 420 is correspondingly smaller, reducing the overall production and manufacturing cost.

[0053] In some embodiments of the present application, the electromagnetic adsorption member 420 is a normally closed electromagnet, which attracts the adsorption member 300 when the normally closed electromagnet is powered off;

[0054] It separates from the adsorption member 300 when the normally closed electromagnet is powered on.

[0055] A normally closed electromagnet is adopted. It can always be in a power-off state and remain attracted to the adsorption component 300 during normal non-throwing. When powered on, it separates from the adsorption component 300 accordingly. When not throwing, the electromagnet does not need to be continuously powered on to maintain attraction, and only needs to be powered on when separating. Compared with the existing way of continuously powering on the electromagnet, it reduces energy consumption and realizes energy saving.

[0056] In some embodiments of the present application, two lever modules are provided and symmetrically connected to both sides of the throwing base 100.

[0057] By respectively arranging lever modules on both sides of the throwing base 100, the weight of the carried object can be evenly distributed to the two lever modules. By reducing the force through the two lever modules respectively, the force acting on the corresponding adsorption component 300 at each lever module is smaller, and the force reduction effect is better.

[0058] For easy understanding, in this embodiment, it is taken as an example that the length from the hook part 230 to the hinge end 210 is 20 cm, and the length from the hook part 230 to the adsorption end 220 is 40 cm for illustration.

[0059] The lever takes point A as the axis. Assuming the heavy object load is 10 kg, when evenly distributed to the two lever modules, it is 5 kg.

[0060] According to the mechanical knowledge related to the lever length and the force application point: power × power arm = resistance × resistance arm, it is calculated that the force acting on the adsorption component 300 is only about 1.6 kg, realizing the force reduction effect.

[0061] In this way, the electromagnetic adsorber 420 used to adsorb the adsorption component 300 only needs a small power to meet the adsorption requirements, reducing the power requirement for the electromagnetic adsorber 420. By using an electromagnetic adsorber 420 with a smaller power, the large-gravity carrying requirement can be met.

[0062] In some embodiments of the present application, the hook part 230 is formed at the bottom position of the force-reducing lever 200, and the distance from it to the hinge end 210 is greater than the distance from it to the adsorption end 220. The weight on the carried object can be mainly transmitted to the hinge end 210 and carried by the throwing base 100 to minimize the force transmitted to the adsorption component 300 and reduce the force required to adsorb the adsorption component 300.

[0063] In some embodiments of the present application, a receiving cavity 411 is formed inside the magnetic conduction base 410, and an oil-filled sealing cavity 412 is formed around the receiving cavity 411. By filling oil in the oil-filled sealing cavity 412, the sealing of the magnetic conduction base 410 is realized.

[0064] A watertight connector 430 is inserted at the top of the magnetic conductive base body 410 and extends to the oil-filled sealing cavity 412.

[0065] The oil-filled sealing cavity 412 is sealed through the watertight connector 430. When filling oil, the watertight connector 430 can be pulled out, and after the oil filling is completed, the watertight connector 430 is inserted for sealing.

[0066] Part of the electromagnetic adsorption member 420 is located in the accommodation cavity 411, and part extends out of the accommodation cavity 411 through the oil-filled sealing cavity 412 to the inside of the wall of the magnetic conductive base body 410.

[0067] Specifically, the electromagnetic adsorption member 420 passes through the oil-filled sealing cavity 412 and extends to the bottom wall position of the magnetic conductive base body 410, corresponding to the adsorption member 300 arranged below it, so as to ensure that the electromagnetic adsorption member 420 is as close as possible to the adsorption member 300 and ensure the adsorption effect on the adsorption member 300.

[0068] In some embodiments of the present application, an insertion part 240 is formed at the adsorption end 220;

[0069] The adsorption member 300 includes an adsorption disc 310 and a convex part 320 protruding from the bottom of the adsorption disc 310, and a threaded part is formed on the convex part 320;

[0070] The adsorption member 300 is inserted into the insertion part 240 through the convex part 320 and locked and fixed by a nut 330, and the adsorption disc 310 is arranged to fit the top surface of the force-reducing lever 200.

[0071] By setting the adsorption member 300 in the structural form of the adsorption disc 310, the contact area between the adsorption member 300 and the electromagnetic adsorption member 420 can be increased, so as to ensure the adsorption firmness between the two, and further ensure the adsorption effect on the carried object, avoid the carried object from falling, and improve the reliability of the entire device.

[0072] In some embodiments of the present application,

[0073] The hooking part 230 is a hooking protrusion formed on the force-reducing lever 200, and a hooking hole with an opening on one side is formed on the hooking protrusion. The carried object can be hung in the hooking hole through the opening on one side to realize the carrying cooperation with the force-reducing lever 200.

[0076] and sub-body frames 120 arranged on both sides of the main body frame 110, and the lever modules are provided between the sub-body frames 120 and the main body frame 110 on both sides.

[0077] In some embodiments of the present application,

[0078] The sub-body frame 120 includes a sub-connector 121, which is vertically arranged and is hinged to the force-reducing lever 200 through a connecting shaft;

[0079] The electromagnetic sealing module 400 is assembled and fixed at a position on one side of the main body frame 110.

[0081] The anchor device includes: a connecting rod 510, one end of which is hinged to the anchor device 600, and an insertion pin is formed at one end, and the insertion pin is inserted into the hook portion 230;

[0082] An elastic tension member 520, one end of which is fixed to the anchor device 600 and the other end is hung on the insertion pin.

[0083] The elastic tension member 520 is a tension spring, and the connecting rod 510 can be tightened through the tension spring to ensure that the connecting rod 510 and the force-reducing lever 200 are firmly clamped and fixed, and are not easily detached.

[0084] In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0085] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, for those of ordinary skill in the art, it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions required to be protected by the present invention.
