Description

Technical Field

[0001] This invention relates to the field of rocket launch technology, and in particular to a manual adjustment device for the diameter of a rocket launcher directional device for a manned rocket launcher. Background Technology

[0002] During weather modification operations, hail suppression and rain enhancement rocket launchers generally adopt a single-channel structure, meaning that only one type of rocket can be launched from one channel. When launching rockets of different diameters, this type of launcher requires different rocket launchers to be set up at the same location, which increases the cost and time of rocket launch.

[0003] Chinese invention application CN 211855057 U discloses an adaptive artificial rainmaking and hail suppression rocket launcher and control system. This launcher uses electric actuators to push connecting rods within two channels. These connecting rods drive a moving component to move up and down, thereby changing the envelope diameter of a U-shaped track. Displacement sensors arranged at the front and rear detect the distance between the U-shaped tracks, thus controlling the diameter of the U-shaped track's envelope. Decreasing or increasing the diameter of the U-shaped track's envelope is achieved by controlling the electric actuator's forward and reverse rotation. Adjusting the U-shaped track to the moving component's limit position avoids interference with the launch of an 88mm diameter rocket, and the launch of the 88mm diameter rocket is achieved via the U-shaped track.

[0004] The aforementioned invention patent relies on slide rails, electric actuators, displacement sensors, control boards, and control logic to enable the same rocket launcher to launch rockets of different diameters. However, the large number of slide rails in each channel results in high procurement costs, and the electric actuators, displacement sensors, control boards, and control logic required for control make the technology difficult to implement and hinder its widespread adoption.

[0071] To better understand the purpose, structure, and function of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. Embodiment 1

[0072] Refer to Figure 1-6 As shown in the figure, a manual diameter adjusting device for a directional device of a rocket launcher for cloud seeding in an embodiment of the present application is described, which includes a track assembly and a support and fixing assembly;

[0073] The support and fixing assembly includes a first track supporting frame 1, a second track supporting frame 2, a third track supporting frame 3, and a fourth track supporting frame 4 arranged in a straight line in sequence;

[0074] The first track supporting frame 1, the second track supporting frame 2, the third track supporting frame 3, and the fourth track supporting frame 4 have the same structure, and are all "day" - shaped frame structures placed horizontally; each "day" - shaped frame structure includes openings on both the left and right sides, and the openings on the left and right sides of the first track supporting frame 1, the second track supporting frame 2, the third track supporting frame 3, and the fourth track supporting frame 4 correspond to each other;

[0075] The track assembly includes a first U - shaped track group 5 and a second U - shaped track group 6 respectively inserted into the openings on the left and right sides of the support and fixing assembly. The openings on the left and right sides of the support and fixing assembly include the openings on the left and right sides of the first track supporting frame 1, the second track supporting frame 2, the third track supporting frame 3, and the fourth track supporting frame 4;

[0076] The first U - shaped track group 5 includes a first upper - side U - shaped large track 501, a first upper - side U - shaped small track 502, a first lower - side U - shaped large track 503, and a first lower - side U - shaped small track 504;

[0077] The first upper - side U - shaped large track 501 is arranged at the upper end of the left - hand opening of the support and fixing assembly with its opening facing downwards, and the first upper - side U - shaped small track 502 is arranged with its opening facing downwards and can move up and down inside the first upper - side U - shaped large track 501;

[0078] The first lower - side U - shaped large track 503 is arranged at the lower end of the left - hand opening of the support and fixing assembly with its opening facing upwards; the first lower - side U - shaped small track 504 is arranged with its opening facing upwards and can move up and down inside the first lower - side U - shaped large track 503;

[0079] The second U-shaped track group 6 has the same structure as the first U-shaped track group 5;

[0080] The second U-shaped track group 6 includes a second upper U-shaped large track, a second upper U-shaped small track, a second lower U-shaped large track, and a second lower U-shaped small track;

[0081] The first upper U-shaped small track 502 and the second upper U-shaped small track are linked by the first linkage rod 7; the first lower U-shaped small track 504 and the second lower U-shaped small track are linked by the second linkage rod 8.

[0082] A linkage plate 9 is provided between the first U-shaped track group 5 and the second U-shaped track group 6. A first inclined groove 901 and a second inclined groove 902 are provided on the side wall of the linkage plate 9. The inclined directions of the first inclined groove 901 and the second inclined groove 902 are mirror images of each other.

[0083] The first linkage rod 7 and the second linkage rod 8 pass through the first inclined groove 901 and the second inclined groove 902, respectively.

[0084] Specifically, the first linkage rod 7 enables the same-direction movement linkage between the first upper U-shaped small track 502 and the second upper U-shaped small track, and the second linkage rod 8 enables the same-direction movement linkage between the first lower U-shaped small track 504 and the second lower U-shaped small track.

[0085] The first linkage 7 and the second linkage 8 pass through the first inclined groove 901 and the second inclined groove 902, respectively. Since their inclined directions are mirror-image, when the linkage plate 9 moves back and forth, the first linkage 7 and the second linkage 8, passing through the first inclined groove 901 and the second inclined groove 902, will rise or fall along the directions of the first inclined groove 901 and the second inclined groove 902, respectively. When the first linkage 7 rises, the second linkage 8 will fall; when the first linkage 7 falls, the second linkage 8 will rise, causing the upper and lower U-shaped small tracks of the two sets of U-shaped track groups to move in opposite directions or in the same direction. When the upper and lower U-shaped tracks move in opposite directions to their extreme positions, they will retract into the interior of the upper and lower U-shaped tracks, respectively. At this point, the U-shaped track can accommodate rockets with the largest diameter, and it carries the rocket. Conversely, when the upper and lower U-shaped tracks move in the same direction to their extreme positions, they will be located outside the upper and lower U-shaped tracks, respectively. At this point, the U-shaped track can accommodate rockets with the smallest diameter, and it carries the rocket.

[0086] The U-shaped track and the linkage rod can be connected in the following way:

[0087] First lifting support seats 10 are provided on the horizontal plates of the first upper U-shaped small track 502 and the second upper U-shaped small track. First lifting support seat holes are opened on the horizontal plates of the first upper U-shaped large track 501 and the second upper U-shaped large track. The upper ends of the two first lifting support seats 10 pass through the two first lifting support seat holes respectively and are connected to the two ends of the first linkage rod 7 respectively.

[0088] The first lower U-shaped small track 504 and the second lower U-shaped small track are each provided with a second lifting support seat 11 on their horizontal plates. The first lower U-shaped large track 503 and the second lower U-shaped large track are each provided with a second lifting support seat hole. The lower ends of the two second lifting support seats 11 pass through the two second lifting support seat holes and are respectively connected to the two ends of the second linkage rod 8.

[0089] Specifically, by setting up lifting support seats on the horizontal plate of the U-shaped small track and drilling holes in the U-shaped large track, the stability of the connection between the U-shaped small track and the linkage rod can be ensured, and the U-shaped large track can be guaranteed not to be affected, thus ensuring that the U-shaped small track can move up and down within the U-shaped large track. Example 2

[0090] See Figure 2 , Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that a tie rod 12 is slidably passed through the support assembly, and the tie rod 12 passes through the center of the first rail frame 1, the second rail frame 2, the third rail frame 3 and the fourth rail frame 4 in sequence.

[0091] The pull rod 12 also passes through the linkage plate 9 and is fixedly connected to the linkage plate 9;

[0092] The two ends of the pull rod 12 are located on the opposite outer sides of the first rail frame 1 and the fourth rail frame 4, respectively;

[0093] A limit block 13 is provided at one end of the pull rod 12 near the fourth rail frame 4; a handle 14 is provided at the one end of the pull rod 12 near the first rail frame 1.

[0094] Specifically, the linkage plate 9 is moved back and forth by the pull rod 12, and is located at the center of the first support frame 1, the second support frame 2, the third support frame 3 and the fourth support frame 4. This provides further support for the linkage plate 9, and makes it easier and faster to move the linkage plate 9. It ensures that the movement direction is a straight line and prevents deviation. The handle 14 is easy to grip, and the limit block 13 can prevent the pull rod 12 from being pulled out of place.

[0095] In addition, four rod holes 15 are opened along the length of the rod at one end of the rod 12 near the first support frame 1;

[0096] A positioning plate 16 is provided on the side of the first support frame 1. The positioning plate 16 has an "L" shaped structure and is located above the tie rod 12. A tie rod positioning hole 17 is opened on the horizontal plate of the positioning plate 16, and a limit pin 18 is inserted into the tie rod positioning hole 17.

[0097] Specifically, the four pull rod holes 15 can be set sequentially as 44mm diameter pull rod hole, 56mm diameter pull rod hole, 66mm diameter pull rod hole and 88mm diameter pull rod hole in the direction from handle 14 to limit block 13.

[0098] When the 44mm diameter pull rod hole is directly below the pull rod positioning hole 17, the pull rod 12 is pulled out to its minimum. The first linkage rod 7 and the second linkage rod 8 are at their closest distance under the constraints of the first inclined groove 901 and the second inclined groove 902, respectively. That is, the first upper U-shaped small track 502 and the second upper U-shaped small track 502 will be at their lowest relative positions, and the first lower U-shaped small track 504 and the second lower U-shaped small track will be at their highest relative positions. At this time, the diameter of the envelope circle formed between the first upper U-shaped small track 502 and the first lower U-shaped small track 504 is the smallest, which can accommodate a rocket with a diameter of 44mm. The same applies to the second upper U-shaped small track and the second lower U-shaped small track. At this time, the limiting pin 18 is inserted into the pull rod positioning hole 17 and the 44mm diameter pull rod hole in sequence to lock the pull rod 12 so that it cannot slide, ensuring that the diameter of the envelope circle formed between the U-shaped small tracks cannot be changed when the next 44mm rocket is launched.

[0099] Correspondingly, when it is necessary to launch a 56mm diameter rocket, simply pull out the limiting pin 18 again, move the 56mm diameter pull rod hole to the bottom of the pull rod positioning hole 17, and then reinsert the limiting pin 18 into the pull rod positioning hole 17 and the 56mm diameter pull rod hole. The same adjustment method is used to launch 66mm or 88mm diameter rockets. Example 3

[0100] See Figure 2 , Figure 4 As shown, the difference between this embodiment and embodiment two is that a positioning block 19 is provided on the side of the second rail frame 2, and the positioning block 19 is located above the first upper U-shaped large rail 501.

[0101] The positioning block 19 is provided with a fourth step 20, a third step 21, a second step 22 and a first step 23 arranged sequentially from bottom to top and from longest to shortest;

[0102] A positioning hole is provided at the top of the fourth step 20, the third step 21, the second step 22 and the first step 23; a positioning seat 24 is provided on the horizontal plate of the first upper U-shaped small track 502, and a positioning seat hole is provided on the horizontal plate of the first upper U-shaped large track 501. The top of the positioning seat 24 passes through the positioning seat hole and is slidably connected to the positioning pin 25. The positioning pin 25 is adapted to all four positioning holes. A positioning baffle 26 is provided at the end of the positioning pin 25 near the positioning hole. A positioning spring 26 is sleeved on the positioning pin 25 between the positioning baffle 26 and the positioning seat 24.

[0103] The height spacing between two adjacent positioning holes on the fourth step 20, the third step 21, the second step 22 and the first step 23 are respectively adapted to the length spacing between two adjacent tie rod holes 15;

[0104] Specifically, the heights of the positioning holes of the fourth step 20, the third step 21, the second step 22, and the first step 23 correspond to the launch of rockets with diameters of 44mm, 56mm, 66mm, and 88mm, respectively.

[0105] In addition, a steel wire rope 28 is connected to the end of the positioning pin 25 that is away from the positioning block;

[0106] like Figure 2 , Figure 5 As shown, a sliding bolt seat 29 is provided above the first upper U-shaped large track 501. The sliding bolt seat 29 has a cavity inside. A long strip-shaped main through groove 30 is provided on the upper surface of the sliding bolt seat 29. A first secondary through groove 31, a second secondary through groove 32, a third secondary through groove 33 and a fourth secondary through groove 34 are provided on the left and right sides of the main through groove 30. The first secondary through groove 31, the second secondary through groove 32, the third secondary through groove 33 and the fourth secondary through groove 34 are arranged alternately in sequence.

[0107] The length distance between two adjacent secondary channels 31, 32, 33 and 34 of the first secondary channel 31 and the second secondary channel 32 is adapted to the length distance between two adjacent steps on the fourth step 20, the third step 21, the second step 22 and the first step 23, respectively.

[0108] Specifically, the first auxiliary through slot 31, the second auxiliary through slot 32, the third auxiliary through slot 33 and the fourth auxiliary through slot 34 correspond to rockets with diameters of 44mm, 56mm, 66mm and 88mm, respectively.

[0109] The words "44 bullet", "56 bullet", "66 bullet" and "88 bullet" can be written near the first auxiliary through slot 31, the second auxiliary through slot 32, the third auxiliary through slot 33 and the fourth auxiliary through slot 34 respectively. The word "fixed position" can be written near the top of the main through slot 30 for the convenience of operators.

[0110] A sliding bolt 35 is movably provided inside the sliding bolt seat 29. The sliding bolt has an "L" shaped structure, and the vertical rod of the sliding bolt 35 passes through the main through groove 30 and extends out of the sliding bolt seat 29, located outside the sliding bolt seat 29.

[0111] One end of the wire rope 28 is connected to the positioning pin 25, and the other end of the wire rope 28 is connected to the horizontal bar of the sliding bolt 35.

[0112] Specifically, when it is necessary to adjust the diameter of the projectile launched from the launcher, the sliding bolt 35 is pulled in the main through groove 30, which in turn pulls the positioning pin 25 through the transmission of the wire rope 28. This causes the positioning pin 25, which is inserted into the positioning hole, to be pulled out. During the adjustment of the projectile diameter by pulling the lever 12, the positioning pin 25 moves up and down with the up and down movement of the first upper U-shaped small track 502. After the adjustment is completed, the sliding bolt 35 can be released. Under the action of the positioning spring 27, the positioning pin 25 extends back into the corresponding positioning hole, further enhancing the stability of the launcher after the projectile diameter adjustment is completed. With the double locking of the positioning pin 25 and the limiting pin 18, it is ensured that the diameter of the envelope circle formed between the U-shaped small tracks of the same U-shaped track group cannot be changed due to vibration when the next rocket launch operation is carried out.

[0113] The launcher can be further optimized, such as:

[0114] The first U-shaped track group 5 is also equipped with a reset mechanism, which includes a top reset plate 36 on the top left side of the second track frame 2 and a bottom reset plate 39 on the bottom left side.

[0115] A top reset hole is provided on the top reset plate 36, and a top reset spring seat 37 is slidably connected in the top reset hole. One end of the top reset spring seat 37 passes through the top reset hole.

[0116] A top spring hole is provided on the horizontal plate of the first upper U-shaped large track 501, and the other end of the top reset spring seat 37 passes through the top spring hole and connects to the horizontal plate of the first upper U-shaped small track 502.

[0117] A top reset spring 38 is fitted on the outer surface of the top reset spring seat 37 between the horizontal plate of the first upper U-shaped small track 502 and the top reset plate 36.

[0118] A bottom reset hole is provided on the bottom reset plate 39, and a bottom reset spring seat 40 is slidably connected in the bottom reset hole. One end of the bottom reset spring seat 40 passes through the bottom reset hole.

[0119] A bottom spring hole is provided on the horizontal plate of the first lower U-shaped large track 503, and the other end of the bottom reset spring seat 40 passes through the bottom spring hole and connects to the horizontal plate of the first lower U-shaped small track 504.

[0120] A bottom reset spring 41 is fitted on the outer surface of the bottom reset spring seat 40 between the horizontal plate of the first lower U-shaped small track 504 and the bottom reset plate 39.

[0121] The second U-shaped track group 6 is also equipped with the same reset mechanism as the second U-shaped track group 5.

[0122] It should be noted that multiple reset mechanisms can be set, such as reset mechanisms being set on the third rail frame 3 and the fourth rail frame 4.

[0123] It should be noted that the top return spring 38 and the bottom return spring 41 are always in a compressed state.

[0124] The function of the reset mechanism is mainly reflected in the process of adjusting the launcher from a large projectile diameter to a small projectile diameter. When the positioning pin 25 is pulled out of the positioning hole, the top reset spring 38, which is in a pressed state, will drive the upper U-shaped small track to move downward, and the bottom reset spring 51 will drive the lower U-shaped small track to move upward, thereby reducing the distance between the upper and lower U-shaped small tracks. This allows the projectile diameter adjustment to be completed more quickly, eliminating the need for manual pulling of the lever 12 for adjustment. It is quick, convenient, and saves manpower.

[0125] It should be noted that the horizontal plate of the first upper U-shaped track 501 is provided with a first wire rope mounting seat 42 and a second wire rope mounting seat hole;

[0126] A second wire rope mounting seat 43 is connected to the horizontal plate of the first upper U-shaped small track 502. The end of the second wire rope mounting seat 43 away from the first upper U-shaped small track 502 passes through the second wire rope mounting seat hole.

[0127] The horizontal rod end of the sliding bolt 35 is connected to the first wire rope joint 44, the end of the positioning pin 25 away from the positioning block 19 is connected to the second wire rope joint 45, and the two ends of the wire rope 28 are respectively connected to the first wire rope joint 42 and the second wire rope joint 43.

[0128] The top of the first wire rope mounting base 42 and the second wire rope mounting base 43 are respectively provided with a first wire rope limiting groove and a second wire rope limiting groove, and the wire rope 28 passes through the first wire rope limiting groove and the second wire rope limiting groove respectively.

[0129] The outer surface of the wire rope 28 is covered with a rubber protective sleeve 46, and the wire rope 28 can slide inside the rubber protective sleeve 46.

[0130] The rubber protective sleeve 46 can protect the wire rope 28 and prevent the wire rope 28 from wearing out and aging prematurely; the first wire rope mounting seat 42 and the second wire rope mounting seat 43 can guide and fix the position of the wire rope 28 and prevent the wire rope 28 from bending.

[0131] It should be noted that the first wire rope port 47 is connected to the wire rope 28 on the side of the first wire rope mounting base 42 away from the sliding bolt seat 29, and the second wire rope port 48 is connected to the wire rope 28 on the side of the second wire rope mounting base 43 away from the positioning block 19.

[0132] The adjustment process from a large-diameter bullet to a small-diameter bullet is as follows (taking the adjustment from a 66mm bullet diameter to a 56mm bullet diameter as an example):

[0133] At this time, the rocket launcher is in the 66mm rocket launch position. The vertical spacing of the U-shaped small track is suitable for launching 66mm diameter rockets. At this time, the positioning pin 25 is located in the positioning hole at the top of the second step 22, the sliding bolt 35 is located in the "fixed position", and the limiting pin 18 is inserted into the third pull rod hole of the pull rod 12 (i.e., the 66mm diameter pull rod hole).

[0134] Pull out the limiting pin 18 inserted in the pull rod hole 15, and pull the sliding bolt 35 backward until it reaches the "56 spring" (i.e. the second through groove 32). When the sliding bolt 35 moves backward, it pulls the wire rope 28 backward, which in turn drives the positioning pin 25 to move backward by the same distance. Move the sliding bolt 35 so that it is locked into the "56 spring" (i.e. the second through groove 32). At this time, the positioning pin 25 is located above the top of the third step 21, and the pin head of the positioning pin 25 has passed above the top of the second step 22. Under the action of the return spring, the first upper U-shaped small rail 502 and the second upper U-shaped small rail both move downward, and the first lower U-shaped small rail 504 and the second lower U-shaped small rail both move upward. The first upper U-shaped small rail 502 and the first lower U-shaped small rail 504 move closer to each other, and the second upper U-shaped small rail and the second lower U-shaped small rail also move closer to each other. The first linkage rod 7 and the second linkage rod 8 together drive the linkage plate 9 to move backward, and the linkage plate 9 drives the pull rod 12 to move backward.

[0135] When the first upper U-shaped small track 502 drives the positioning pin 25 to contact the upper surface of the third step 21, the positioning pin 25 plays a limiting role on the first upper U-shaped small track 502, the first upper U-shaped small track 502 stops moving, the pull rod 12 stops moving, and at this time the second pull rod hole (i.e. the 56mm spring diameter pull rod hole) corresponds to the pull rod positioning hole 17.

[0136] Move the sliding bolt 35 back into the main channel 30, and slightly push the handle 14. The positioning pin 25 is inserted into the positioning hole at the top of the third step 21 under the action of the positioning spring 27. Insert the limit pin 18 into the pull rod positioning hole 17 and the second pull rod hole (i.e., the 56mm diameter pull rod hole) to lock the pull rod 12. At this time, the rocket launcher is adjusted to the 56mm diameter rocket launch state.

[0137] The adjustment process from 88mm to 66mm, 88mm to 56mm, 88mm to 44mm, 66mm to 44mm, and 56mm to 44mm is similar to the adjustment process described above.

[0138] The adjustment process from a small-diameter bullet to a large-diameter bullet is as follows (taking the adjustment from a 56mm bullet diameter to a 66mm bullet diameter as an example):

[0139] At this time, the rocket launcher is in the 56mm rocket launch position. The vertical spacing of the U-shaped small track is suitable for launching 56mm diameter rockets. At this time, the positioning pin 25 is located in the positioning hole at the top of the third step 21, the sliding bolt 35 is located in the "fixed position", and the limiting pin 18 is inserted into the second pull rod hole (i.e. the pull rod hole for 56mm diameter rockets).

[0140] Pull the sliding bolt 35 backward until it reaches the "44 spring" (i.e., the first through groove 31). The sliding bolt 35 pulls the wire rope 28 backward, which in turn moves the positioning pin 25 backward by the same distance. Move the sliding bolt 35 so that it is locked into the "44 spring" (i.e., the first through groove 31). At this time, the positioning pin 25 is located above the top of the fourth step 20, and the pin head of the positioning pin 25 has passed above the top of the third step 21. Pull the lever 12 backward slightly by the handle 14 to pull out the limiting pin 18 inserted in the second lever hole (i.e., the 56mm spring diameter lever hole).

[0141] Then, by pulling the lever 12 through the handle 14, the lever 12 simultaneously drags the linkage plate 9 forward. The first linkage rod 7 and the second linkage rod 8 slide in the first inclined groove 901 and the second inclined groove 902 respectively. The first linkage rod 7 drives the first upper U-shaped small track 502 and the second upper U-shaped small track to move upward together through the first lifting support seat 10. The second linkage rod 8 drives the first lower U-shaped small track 504 and the second lower U-shaped small track to move downward together through the second lifting support seat 11 until the third lever hole (i.e., the lever hole with a spring diameter of 66mm) is aligned with the lever positioning hole 17.

[0142] Move the sliding bolt 35 back into the main channel 30. Under the action of the positioning spring 27, the positioning pin 25 is inserted into the positioning hole at the top of the second step 22. The sliding bolt 35 moves back to the "fixed position". Insert the limit pin 18 into the pull rod positioning hole 17 and the third pull rod hole (i.e., the 66mm diameter pull rod hole) to lock the pull rod 12. At this time, the rocket launcher is adjusted to the 66mm diameter rocket launch state.

[0143] The adjustment process from 44mm to 56mm, 44mm to 66mm, 44mm to 88mm, 56mm to 88mm, and 66mm to 88mm is similar to the adjustment process described above.
