[0025] Secondly, the circumferential surfaces of the male head I and the female head are both knurled to increase the friction between the extension rod and the hand, facilitating the splicing of the extension rod;

[0026] Furthermore, the main rod I is made of hollow carbon fiber material, which not only ensures the stiffness and strength of the supporting rod and the hook rod, but also reduces the weight of the supporting rod and the hook rod, facilitating the use, holding and placing of the supporting rod and the hook rod.

[0027] 4. The male head of the present invention is composed of multiple parts. A blank with a relatively thin wall thickness can be selected, and less material needs to be machined and removed, which can save the waste of materials to the greatest extent and reduce the production cost. Moreover, separate processing can avoid the problems of large processing difficulty and easy deformation. Secondly, circumferential positioning is carried out through the positioning pin to prevent axial rotation, and at the same time, an adhesive is used for filling and bonding to ensure the reliable connection between the main rod and the male head I and the sealing performance of the supporting rod and the hook rod.

DETAILED DESCRIPTION OF THE INVENTION

[0034] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0035] The present invention provides a deployment and recovery auxiliary device suitable for underwater vehicles, comprising a support head 1, a hook head 4, an extension rod 2 and a tail rod 3. Figures 1 to 3 shown.

[0036] The support head 1 is connected to the extension rod 2 by threads, and the extension rod 2 is connected to the tail rod 3 by threads to form the support rod; the hook head 4 is connected to the extension rod 2 by threads, and the extension rod 2 is connected to the tail rod 3 by threads to form the hook rod. O-rings 13 are provided between the support head 1 and the extension rod 2, between the hook head 4 and the extension rod 2, and between the extension rod 2 and the tail rod 3 for sealing to prevent water from flowing into the extension rod 2 and the tail rod 3 and increasing the weight of the support rod.

[0037] The support head 1 of the support rod is made of metal material Ⅰ5 and vulcanized rubber Ⅰ6.

[0038] The hook head 4 of the hook rod is made of metal material II14 and vulcanized rubber II15.

[0039] like Figure 4 As shown, the extension rod 2 includes a male head Ⅰ7, a female head 9 and a main rod Ⅰ8; the main rod Ⅰ8 is a hollow structure and is made of carbon fiber material, which not only ensures the rigidity and strength of the support rod and the hook rod, but also reduces the weight; the circumferential surfaces of the male head Ⅰ7 and the female head 9 are knurled to increase the friction between the extension rod 2 and the hand and facilitate the splicing of the extension rod 2; the two ends of the main rod Ⅰ8 are fixedly connected to the male head Ⅰ7 and the female head 9 respectively, and the fixed connection of multiple main rods Ⅰ8 is achieved through the cooperation between the male head Ⅰ7 and the female head 9.

[0040] Specifically, Figure 5 As shown, the male head Ⅰ7 includes a male thread head 16, a male thread adapter seat 17, a male screw sleeve 18 and an adapter inner sleeve 20; the tail end of the male thread head 16 is connected to the male thread adapter seat 17 through a thread, and the outer wall surface of the tail end of the male thread head 16 and the inner wall surface of the front end of the male thread adapter seat 17 are provided with an annular groove, and the tail end of the male thread head 16 and the head of the male thread adapter seat 17 are provided with an inclined surface, which is connected with the annular groove through the inclined surface and welded at the joint of the inclined end surface; the male thread adapter seat 1 The tail end of 7 is connected to the male screw sleeve 18 through a thread, the head of the main rod I8 is bonded in the gap between the male thread adapter seat 17 and the male screw sleeve 18, the adapter inner sleeve 20 is bonded to the main rod I8 through an adhesive 19, and the head of the adapter inner sleeve 20 is interference fit with the male thread adapter seat 17; the outer circumference of the male screw sleeve 18 is provided with a positioning pin, which further plays a role in circumferential and axial positioning, and fixes the male thread adapter seat 17, the main rod I8, the male screw sleeve 18 and the adapter inner sleeve 20 together.

[0041] If the male-threaded head 16 and the male-threaded adapter seat 17 are processed as one part, the wall thickness of the corresponding blank is relatively thick, and more material needs to be removed during processing. Separating the processing of the male-threaded head 16 and the male-threaded adapter seat 17 allows for the selection of two blanks with relatively thin wall thicknesses, reducing the amount of material removed during processing and maximizing the savings in material waste and reducing production costs.

[0042] If the male-threaded adapter seat 17 and the adapter inner lining sleeve 20 are processed as one part, similar to the description above, the cost is high, and the length of the adapter inner lining sleeve 20 is relatively long, resulting in a relatively deep overall boring depth, making the processing difficult and prone to deformation. Separating the processing can avoid the problems of difficult processing and easy deformation.

[0043] Using the adapter inner lining sleeve 20 can increase the bonding area between the metal part of the male head 7 and the main rod 8, improving the reliability of the bonding.

[0044] Preferably, the head of the adapter inner lining sleeve 20 is a variable-diameter section, which can accommodate more adhesive 19 and is more conducive to the adhesion of the adhesive 19; there is a gap between the outer wall of the middle part of the adapter inner lining sleeve 20 and the inner wall of the main rod 8, and the tail of the adapter inner lining sleeve 20 is an expansion section until it contacts the inner wall of the main rod 8, facilitating the insertion of the main rod 8 and enabling radial positioning, improving the coaxiality of the male-threaded head 16 and the main rod 8, and ensuring the coaxiality after the extension rod 2 is connected.

[0045] The installation method of the male head 7 is as follows:

[0046] Step 1, the tail end of the male-threaded head 16 is threadedly connected inside the male-threaded adapter seat 17, and the connection end faces of the two are welded.

[0047] Step 2, the tail end of the male-threaded adapter seat 17 is threadedly connected inside the male-threaded sleeve 18, and the head of the adapter inner lining sleeve 20 is in interference fit with the male-threaded adapter seat 17, thus completing the connection of the male-threaded head 16, the male-threaded adapter seat 17, the male-threaded sleeve 18, and the adapter inner lining sleeve 20.

[0048] Step 3, apply the adhesive 19 to the outer circumferential surface of the adapter inner lining sleeve 20, and insert the main rod 8 into the gap between the male-threaded adapter seat 17 and the male-threaded sleeve 18 through the guidance of the adapter inner lining sleeve 20.

[0049] Step 4, after the adhesive 19 solidifies, install the positioning pin in the circumferential direction of the male-threaded sleeve 18 using the riveting process to fix the male-threaded adapter seat 17, the main rod 8, the male-threaded sleeve 18, and the adapter inner lining sleeve 20 together.

[0050] The tail rod 3 includes a male head II 10, a tail cover 12, and a main rod II 11; the main rod II 11 is a hollow structure made of carbon fiber material, which not only ensures the stiffness and strength of the support rod and the hook rod, but also reduces the weight; the circumferential surface of the male head II 10 is knurled to increase the friction between the tail rod 3 and the hand, facilitating the splicing of the extension rod 2 and the tail rod 3; the two ends of the main rod II 11 are fixedly connected to the male head II 10 and the tail cover 12 respectively. The tail cover 12 is made of non-metallic material, which reduces the weight of the support rod and the hook rod and also prevents water from flowing into the extension rod 2 and the tail rod 3.

[0051] The structure of the male head II 10 is the same as that of the male head I 7, and the connection method between the male head II 10 and the main rod II 11 is the same as that between the male head I 7 and the main rod I 8.

[0052] When the underwater vehicle is deployed and recovered, with the assistance of the support rod, it can prevent the underwater vehicle from colliding with the dock; with the assistance of the hook rod, it can prevent the underwater vehicle from drifting away with the waves; with the assistance of the support rod and the hook rod together, it can prevent the underwater vehicle from being affected by environmental factors such as surface waves and wind, which increases the difficulty of hooking and unhooking the lifting hook.

[0053] When the underwater vehicle is deployed and recovered, according to the vertical distance from the operation dock to the water surface and the deployment and recovery environment, multiple extension rods 2 can be spliced together to extend the operation range of the support rod and the hook rod.

[0054] The device has a simple structure, mature technology, and reliable materials. When the underwater vehicle is deployed and recovered under complex and harsh environmental conditions, it can complete the operation tasks safely, reliably, and quickly, greatly improving the combat effectiveness of the underwater vehicle.

[0055] In summary, the above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
