Description

Technical Field

[0001] The present invention relates to the technical field of shipborne rocket deployment, and in particular to a multi-firing angle driving mechanism of a shipborne rocket deployment system. Background Art

[0002] With the development and utilization of marine resources in various countries around the world and the improvement of marine navigation safety technology, various types of special buoys have emerged, such as marine meteorological buoys, marine environment monitoring buoys, signal buoys and marine navigation buoys. The above buoys generally include two forms. One is fixed at a certain location for a long time. This type of buoy needs to carry out long-term data collection, navigation and other missions, and maintains its endurance through solar energy. It is generally large in size and weight and needs to be anchored to maintain a fixed position; the other is deployed at a certain location for emergency use, and completes data collection, signal navigation and positioning missions in a short time. The endurance is small and this type of buoy is generally light and small.

[0003] The deployment of large buoys often requires special construction vessels. After the construction vessel sails to the designated deployment point, the buoy is hoisted into the water by lifting equipment (such as a gantry crane) and released to complete the deployment of the buoy. The buoy is stabilized at the deployment point by its anchoring system. The deployment of small buoys is relatively simple, and general ships can meet the requirements. After the ship sails to the designated deployment point, the deployment can be completed with manual assistance. The deployment of such small buoys can also be implemented unmanned by unmanned boats.

[0004] The existing method of deploying small buoys requires the ship to sail to the designated point before the deployment can be completed. The main disadvantages are as follows: (1) High risk. When the sea conditions are poor, there is a great risk of navigation for small-tonnage deployment ships to reach the deployment point. When the bottom is complex, there is a great risk of large ships hitting the bottom when arriving at the deployment point. Therefore, there is a risk of damage to the ship and equipment when deploying buoys, and it may even cause casualties. (2) Low efficiency. Buoys are often present in a multi-point array, so multiple buoys need to be deployed. The existing deployment method requires that the construction ship needs to sail to another deployment point after completing the deployment at one deployment point, which is inefficient. Summary of the invention

[0005] In view of this, the present invention provides a multi-angle driving mechanism for a shipborne rocket deployment system, which can complete the deployment and navigation risks remotely and realize the simultaneous deployment of buoys at multiple different deployment points, thereby improving efficiency and accuracy.

[0006] The present invention is achieved through the following technical solutions: a multi-launch angle drive mechanism of a shipborne rocket deployment system, comprising a base, a drive device, a turbine worm pair, a transmission shaft, a plurality of gear pairs and a plurality of corresponding launch rails, wherein the launch rails are used to place rockets mounted with buoys; the drive device is fixed to the outside of the base, and the transmission shaft arranged in the base is rotated through the turbine worm pair, and the transmission shaft drives the corresponding plurality of launch rails to rotate through a plurality of gear pairs; each group of gear pairs has the same module and the same sum of the number of teeth, and the number of teeth of the driving gear is different, so that each launch rail rotates to form a different initial launch angle of the rocket.

[0007] Furthermore, several groups of gear pairs are respectively composed of driving gears 1a, 2a, 3a, ..., na, and corresponding driven gears 1b, 2b, 3b, ..., nb, and the number of teeth of the driving gears 1a, 2a, 3a, ..., na and the driven gears 1b, 2b, 3b, ..., nb are Z1a, Z2a, Z3a, ..., Zna and Z1b, Z2b, Z3b, ..., Znb respectively, and n is a positive integer; the relationship between the initial launching angles α1, α2, α3, ..., αn of several launching guides is α1: α2: α3: ...: αn = (Z1a / Z1b): (Z2a / Z2b): (Z3a / Z3b): ...: (Zna / Znb).

[0008] Furthermore, the driving device is connected to the worm of the worm gear pair through a flat key I, the worm is fixed to the outside of the base through a worm sleeve, and the worm and the worm sleeve are rotatably matched; the two ends of the transmission shaft are fixed to both sides of the base through transmission shaft sleeves, the transmission shaft and the transmission shaft sleeve are rotatably matched, and one end of the transmission shaft extends out of the base and is connected to the turbine of the worm gear pair through a flat key II.

[0009] Furthermore, several driving gears are circumferentially fixed on the transmission shaft at the same intervals through flat key III, and are all axially fixed to the transmission shaft through fasteners; a rotating support shaft whose axis is parallel to the axis of the transmission shaft is also fixed on the base, and several launching guides are fixed to the same side of the corresponding driven gears through fasteners, and the rotating support shaft passes through several driven gears and launching guides, and the driven gears and launching guides can rotate relative to the rotating support shaft together.

[0010] Furthermore, gear washers are provided between the launching guide rail abutting against the base and the base, between the driven gear abutting against the base and the base, and between the driven gear and the adjacent launching guide rail not fixed thereto.

[0011] Furthermore, the driving device includes a motor and a reducer, and the motor outputs torque through the reducer to drive the worm gear pair to rotate the transmission shaft.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In the present invention, each group of gear pairs has the same module and the same sum of the number of teeth, and the number of teeth of the driving gear is different, so that each launching guide rail rotates to form a different initial launching angle, which can realize long-distance deployment in the air. There is no need to sail the ship to the deployment point. It is only necessary to obtain the distance between the berthing point and the deployment point, and calculate the initial launching angle to achieve deployment, which greatly reduces the risk of the impact of sea conditions on the ship's navigation process. Moreover, through different initial launching angles, buoys at deployment points at different distances in the same horizontal direction can be deployed simultaneously, which greatly improves the deployment efficiency.

[0014] 2. The driving gears in the gear pair of the present invention are all connected to the same transmission shaft through a flat key III, and the driven gears are respectively fixedly connected to the corresponding launch guide rails and can rotate around the same rotating support shaft; the structure is greatly simplified and the installation is convenient.

[0015] 3. The motor and reducer of the present invention drive the transmission shaft through the worm gear, and the transmission shaft drives the corresponding launch guide rail through the gear set, which can achieve both speed reduction and torque increase and self-locking of the launch guide rail.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] The shipborne rocket deployment system is often carried out by unguided rockets carrying light and small underwater structures such as buoys to the preset deployment points. The trajectory of the launch is affected by the initial launch angle, so its deployment distance mainly depends on the initial launch angle. The present invention provides a multi-launch angle drive mechanism for a shipborne rocket deployment system, which can realize that one motor drives multiple launch rails at the same time to form a variety of different initial launch angles, and a rocket with a buoy mounted on each launch rail is placed, thereby realizing multiple deployment points at different distances.

[0022] like Figure 1 As shown, the mechanism includes a base 16, a driving device, a turbine worm pair, a transmission shaft 5, several groups of gear pairs and several corresponding launch rails, and the launch rails are used to place the rocket carrying the buoy; the driving device is fixed to the right side of the base 16, and the transmission shaft 5 arranged in the base 16 is rotated through the turbine worm pair, and the transmission shaft 5 drives the corresponding several launch rails to rotate through several groups of gear pairs; each group of gear pairs has the same module and the same sum of the number of teeth, and the number of teeth of the driving gear is different, so that each launch rail rotates to form a different initial launch angle of the rocket, so as to realize the deployment of multiple different distances.

[0023] In this embodiment, the driving device includes a motor and a reducer connected thereto. The fixed ends of the motor and the reducer 1 are fastened to the base 16. The motor drives the worm gear pair through the output torque of the reducer to rotate the transmission shaft 5. Specifically, the output end of the reducer is connected to the worm 3 of the worm gear pair through a flat key Ⅰ2. The upper and lower ends of the worm 3 are provided with worm sleeves 8. The worm sleeves 8 are fixed to the right side of the base 16. The worm 3 rotates with the worm sleeves 8. The two ends of the transmission shaft 5 are provided with transmission shaft sleeves 17. The transmission shaft sleeves 17 are fixed to the base 16. The transmission shaft 5 rotates with the transmission shaft sleeves 17, and one end of the transmission shaft 5 extends out of the base 16 and is connected to the turbine 7 of the worm gear pair through a flat key Ⅱ6. The turbine 7 can be axially fixed to the transmission shaft 5 through the turbine retaining ring 4.

[0024] In this embodiment, three groups of gear pairs are provided, which are respectively composed of a driving gear 1a9, a driving gear 2a12, a driving gear 3a14 and corresponding driven gears 1b11, 2b13 and 3b15. The three groups of gear pairs have the same module, and the total number of teeth of each group of gear pairs is the same. The number of teeth of the driving gear 1a9, the driving gear 2a12 and the driving gear 3a14 is different, so the number of teeth of the driven gear 1b11, the driven gear 2b13 and the driven gear 3b15 is different. The number of teeth of the driving gear and the driven gear are Z1a, Z2a, Z3a, Z1b, Z2b and Z3b respectively. The driving gear 1a9, the driving gear 2a12 and the driving gear 3a14 are fixed on the transmission shaft 5 circumferentially by the flat key III10 in sequence from right to left with the same spacing, and are all fixed on the transmission shaft 5 axially by the set screws. The turbine 7 rotates to drive the transmission shaft 5 to drive the driving gear 1a9, the driving gear 2a12 and the driving gear 3a14 to rotate relative to the transmission shaft sleeve 17.

[0025] A rotating support shaft 19 whose axis is parallel to the axis of the transmission shaft 5 is also fixed on the base 16. The three launch rails (launch rail I 22, launch rail II 21, launch rail III 20) are all fixedly connected to the left side of their corresponding driven gears by screws; the rotating support shaft 19 passes through the driven gear 1b11, the driven gear 2b13, the driven gear 3b15 and the launch rail I 22, the launch rail II 21, and the launch rail III 20, corresponding to the three driving gears, the driven gear 1b11, the driven gear 2b13, the driven gear 3b15 and the launch rail are arranged from right to left in sequence with the same spacing, the driven gear and the launch rail can rotate relative to the rotating support shaft 19 together, and the three groups of rockets and buoys are placed on the three launch rails respectively to achieve three different initial launch angles. The motor and the reducer 1 drive the transmission shaft 5 through the worm gear pair, and the transmission shaft 5 drives the corresponding launch rail through the gear pair, which can achieve both deceleration and torque increase and self-locking of the launch rail.

[0026] A gear washer 18 is provided between the launching guide rail abutting against the base 16 and the base 16, a gear washer 18 is provided between the driven gear abutting against the base 16 and the base 16, and a gear washer 18 is provided between the driven gear and the adjacent launching guide rail that is not fixed thereto; in the present embodiment, gear washers 18 are provided between the launching guide rail III 20 and the left side of the base 16, between the launching guide rail II 21 and the driven gear 3b15, between the launching guide rail I 22 and the driven gear 2b13, and between the driven gear 1b11 and the right side of the base 16.

[0027] The working principle of this mechanism is as follows: the motor and reducer 1 output torque, and drive the transmission shaft 5 after deceleration and torque increase through the turbine 7 and the worm 3, and the transmission shaft 5 drives the driving gear 1a9, the driving gear 2a12, and the driving gear 3a14 to rotate at the same time, and the driving gear 1a9, the driving gear 2a12, and the driving gear 3a14 drive the launch guide rails I, II, and III to rotate through the corresponding driven gears 1b11, 2b13, and 3b15. The modules of the three sets of gear pairs are the same, and the relationship of the number of teeth is: (Z1a+Z1b)=(Z2a+Z2b)=(Z3a+Z3b), and Z1a, Z2a, and Z3a are different from each other, so that the launch guide rails I22, II21, and III20 rotate by angles α1, α2, and α3 respectively, that is, three initial launch angles α1, α2, and α3 are achieved. The relationship between the initial launch angles α1, α2 and α3 of the three groups of launch rails is α1:α2:α3=(Z1a / Z1b):(Z2a / Z2b):(Z3a / Z3b).

[0028] The present invention can realize that one motor drives three launch rails to form three different initial launch angles at the same time, thereby realizing three deployment points at different distances. When deployment is required, the launch level is modulated to a predetermined direction, the motor is started, the three launch rails are driven to a preset launch angle, and ignited and launched at the same time to complete the deployment. The three buoys are deployed at the same time, so the deployment direction is the same and is less affected by the swaying of the ship. It has the advantages of simple system, easy use, high safety and efficient deployment.

[0029] In other embodiments, more gear pairs and corresponding launching rails can be provided according to the space and deployment point array requirements to achieve more initial launching angles, so that buoys at more deployment points can be deployed at the same time, thereby greatly increasing the deployment efficiency.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
