DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Combine the following Figure 1-Figure 6 The invention describes a high-altitude balloon launching device and a control method.

[0026] like Figure 1 As shown, in an embodiment of the present invention, the high-altitude balloon launching device includes: a first base 101, a roller 2, a locking and releasing mechanism 3, a flipping mechanism 5 and a tilt adjustment mechanism 6. The two ends of the roller 2 are respectively connected to the locking and releasing mechanism 3 and the flipping mechanism 5, and the roller 2 is located above the first base 101. The tilt adjustment mechanism 6 includes: a first rotating shaft 601, a first bracket 602, a second bracket 603 and a tilt adjustment assembly. The first bracket 602 is arranged opposite to the second bracket 603, and is rotatably connected to the first rotating shaft 601, and the first rotating shaft 601 is arranged on the first base 101. The first bracket 602 is connected to the locking and releasing mechanism 3, the second bracket 603 is connected to the flipping mechanism 5, and the tilt adjustment assembly is connected to the first bracket 602, and the tilt adjustment assembly is used to drive the first bracket 602 to rotate, thereby driving the roller 2 to rotate.

[0027] Specifically, if Figure 5As shown, the drum 2 includes: a cylinder 201, a third rotating shaft 202 and a bearing 203. The cylinder 201 is connected to the third rotating shaft 202 through the bearing 203, and the cylinder 201 can rotate relative to the third rotating shaft 202. One end of the third rotating shaft 202 is movably connected to the locking and releasing mechanism 3, and the other end of the third rotating shaft 202 is fixedly connected to the flipping mechanism 5. A pair of fourth brackets 102 are provided on the first base 101, and the two ends of the first rotating shaft 601 are rotatably connected to the pair of fourth brackets 102 respectively. When the inclination adjustment component is actuated, it can drive the first bracket 602 to rotate relative to the first rotating shaft 601, and when the first bracket 602 rotates, it can drive the cylinder 201 to rotate. In this embodiment, the inclination adjustment of the drum 2 refers to: adjusting the direction of the bisector of the angle formed by the longitudinal axis of the high-altitude balloon 8 and the uninflated part of the balloon, so that it is located in the plane when the drum 2 is flipped. Specifically, as Figure 2 As shown, the solid line with arrows represents the bisector of the angle formed by the longitudinal axis of the high-altitude balloon 8 and the uninflated part of the balloon, and the dotted line with arrows represents the plane where the drum 2 is turned over. The purpose of adjusting the inclination of the drum 2 is to make the dotted line coincide with the solid line. When the high-altitude balloon 8 is released, the locking and releasing mechanism 3 is opened, the drum 2 is separated from the locking and releasing mechanism 3, and the drum 2 is turned over by the combined action of the turning mechanism 5 and the buoyancy of the high-altitude balloon 8 to release the high-altitude balloon 8.

[0028] The high-altitude balloon launching device provided in the embodiment of the present invention can actively adjust the launching inclination of the roller by providing an inclination adjustment mechanism, thereby achieving adaptation to different inclinations of the roller, reducing the launching risk caused by inclination mismatch, and ensuring the safe launching of high-altitude balloons.

[0029] like Figure 2 As shown, in an embodiment of the present invention, the inclination adjustment assembly includes: a first damper 604, a first slider 605, a first lead screw 606 and a first driver 607. The two ends of the first damper 604 are respectively connected to the first bracket 602 and the first slider 605, the first slider 605 is slidably connected to the first lead screw 606, and the first driver 607 is connected to the first lead screw 606. When the first driver 607 is in motion, it can drive the first lead screw 606 to rotate, and then drive the first slider 605 to slide along the first lead screw 606. When the first slider 605 slides, it can drive the first damper 604 to rotate, so as to drive the first bracket 602 to rotate, and then drive the drum 2 to rotate, so as to achieve the inclination adjustment of the drum 2.

[0030] Optionally, in the embodiment of the present invention, the first driver 607 may be a rocker or a rotary motor.

[0031] In the embodiment of the present invention, the flip mechanism 5 includes: a first flip mechanism and a second flip mechanism, the first flip mechanism is used to drive the roller 2 to flip when releasing the high-altitude balloon 8, and the second flip mechanism is used to drive the roller 2 to reset after the high-altitude balloon 8 is released. When the high-altitude balloon 8 is released, the first flip mechanism is activated, and the second flip mechanism is not activated.

[0032] like Figure 3 As shown, in the embodiment of the present invention, the first flipping mechanism includes: a second rotating shaft 501, a mounting seat 502, a first wheel body 504, a traction rope 505 and a driving assembly. The mounting seat 502 is sleeved on the outside of the second rotating shaft 501, the mounting seat 502 is connected to the drum 2, the first wheel body 504 is sleeved on the outside of the second rotating shaft 501, and the two ends of the traction rope 505 are respectively connected to the first wheel body 504 and the driving assembly.

[0033] Specifically, the third rotating shaft 202 of the drum 2 is connected to the second rotating shaft 501 through the mounting seat 502. One end of the traction rope 505 is wound around the first wheel body 504, and the other end is connected to the driving assembly. When the driving assembly is in operation, the traction rope 505 is pulled, thereby pulling the first wheel body 504 to rotate, and the first wheel body 504 drives the second rotating shaft 501 to rotate, so that the drum 2 is turned over.

[0034] like Figure 4 As shown, the driving assembly includes: an elastic member 506, a moving seat 507, a second lead screw 508, a plurality of second wheels 509, and a second driver. The two ends of the elastic member 506 are respectively connected to the moving seat 507 and the traction rope 505, the traction rope 505 passes through the plurality of second wheels 509 and is connected to the first wheel 504, the moving seat 507 is slidably connected to the second lead screw 508, and the second driver is connected to the second lead screw 508.

[0035] Specifically, one end of the traction rope 505 is wound around the first wheel body 504, and the other end of the traction rope 505 is connected to the elastic member 506 after being guided by a plurality of second wheels 509. When the second driver drives the second lead screw 508 to rotate, the moving seat 507 can slide along the second lead screw 508, thereby driving the elastic member 506 to extend, and the elastic member 506 drives the second rotating shaft 501 to rotate through the traction rope 505, so that the drum 2 is turned over.

[0036] In this embodiment, the elastic member 506 can store energy. For some heavy drums 2, simply relying on the buoyancy of the high-altitude balloon 8 when it is released cannot drive the drum 2 to flip. By providing the elastic member 506, when the elongation of the elastic member 506 is changed, the flipping force of the flipping mechanism 5 is different, so that the heavier drum 2 can be driven to flip.

[0037] Furthermore, in order to increase the turning force when the drum 2 is turned over, the number of the first adjustment mechanism can be a pair, that is, a pair of first wheel bodies 504 are respectively arranged on both sides of the mounting seat 502, and each first wheel body 504 is driven by a driving component. When the two driving components are in operation, the two first wheel bodies 504 simultaneously drive the second rotating shaft 501 to rotate, thereby increasing the turning force when the drum 2 is turned over.

[0038] The high-altitude balloon launching device provided in the embodiment of the present invention can assist the roller in turning over by providing two first adjustment mechanisms, and can adjust the energy storage size to adapt to loads of different sizes, thereby ensuring the normal launch of the high-altitude balloon.

[0039] Optionally, in an embodiment of the present invention, the second driver may also be a rocker or a rotary motor.

[0040] like Figure 4 As shown, in the embodiment of the present invention, the second flipping mechanism includes: a gear 510, a second slider 511, a reducer 512 and a third driver 513. The gear 510 is sleeved on the outside of the second rotating shaft 501, and the second slider 511 is slidably connected to the reducer 512. The second slider 511 is provided with teeth inside so that the second slider 511 can be sleeved and meshed with the gear 510.

[0041] Specifically, after the drum 2 is turned over, the second slider 511 slides and is sleeved on the outside of the gear 510. Since the second slider 511 is provided with teeth, when the second slider 511 and the gear 510 are sleeved, the teeth mesh with the gear 510. When the third driver 513 drives the reducer 512 to rotate, the reducer 512 drives the second slider 511 to rotate, and then drives the second rotating shaft 501 to rotate, so that the drum 2 is reset to the initial position.

[0042] In this embodiment, when the high-altitude balloon 8 is released, the second slider 511 is separated from the gear 510, and the drum 2 can be turned over normally under the drive of the elastic member 506; after the high-altitude balloon 8 is released, the second slider 511 is sleeved and meshed with the gear 510.

[0043] Optionally, in the embodiment of the present invention, the third driver 513 may be a rotary motor.

[0044] like Figure 1 As shown, in an embodiment of the present invention, the high-altitude balloon launching device further includes a buffer mechanism 4, which is connected to the second rotating shaft 501. The buffer mechanism 4 is used for buffering during the turning process of the drum 2 to reduce the shaking of the drum 2 when it turns over.

[0045] like Figure 4As shown, in the embodiment of the present invention, the buffer mechanism 4 includes: a third bracket 401, a flexible member 402 and a pair of second dampers 403. The third bracket 401 is rotatably connected to the second rotating shaft 501, the flexible member 402 is arranged on the third bracket 401, and a pair of second dampers 403 are relatively arranged on both sides of the third bracket 401, and the two ends of each second damper 403 are respectively connected to the third bracket 401 and the first base 101, so that the drum 2 can abut against the flexible member 402 when turning over.

[0046] Specifically, the mounting seat 502 is located between the third brackets 401, and the flexible member 402 is opposite to the flipping direction of the drum 2. When the drum 2 flips, it can touch the flexible member 402, and the flexible member 402 performs a primary energy absorption buffering on the drum 2. When the drum 2 collides with the flexible member 402, the flexible member 402 drives the third bracket 401 to rotate, and the third bracket 401 squeezes the second damper 403 to achieve secondary energy absorption buffering.

[0047] Furthermore, if Figure 4 As shown, the buffer mechanism 4 further includes a third damper 404, which is disposed on the third bracket 401 and is located between the mounting seat 502 and the flexible member 402. The mounting seat 502 is provided with a protrusion 503, and during the turning process of the drum 2, the protrusion 503 collides with the third damper 404 to achieve three times of energy absorption and buffering, thereby ensuring that the drum 2 turns smoothly.

[0048] Optionally, in an embodiment of the present invention, the flexible member 402 is a cushioning cotton.

[0049] The high-altitude balloon launching device provided in the embodiment of the present invention can realize three energy absorption buffers during the roller flipping process by providing a buffer mechanism, thereby reducing the shaking of the roller when flipping and ensuring the smooth flipping of the roller.

[0050] like Figure 6 As shown, the high-altitude balloon launching device also includes a traction mechanism 1, which includes: a first base 101, a pair of fourth brackets 102, a traction joint 103, a plurality of wheels 104, a plurality of legs 105 and a turntable bearing 106. The traction joint 103 is connected to the first base 101, and the traction joint 103 is used to connect to the traction device. The bottom surface of the first base 101 is provided with a plurality of wheels 104 and a plurality of legs 105.

[0051] Furthermore, the high-altitude balloon launching device further comprises a second base 7, which is connected to the first base 101 via a turntable bearing 106. A pair of fourth brackets 102 are disposed on the second base 7, the second base 7 is located below the drum 2, and one end of the second damper 403 is connected to the second base 7.

[0052] The embodiment of the present invention also provides a control method for a high-altitude balloon launching device, comprising the following steps: Step 01: Obtain the direction of the bisector of the angle formed by the longitudinal axis of the spherical bubble and the uninflated part of the sphere; Step 02: Control the action of the inclination adjustment component so that the direction of the bisector is within the flipping plane of the drum 2; Step 03: Control the action of the first flipping mechanism based on the buoyancy of the high-altitude balloon 8; Step 04: Control the locking release mechanism 3 to release the drum 2; Step 05: Control the action of the second flipping mechanism to drive the drum 2 to reset.

[0053] Specifically, the drum 2 is towed to the target site by the traction mechanism 1; the multiple legs 105 of the traction mechanism 1 are propped up; the drum 2 is rotated to a direction in which the axis of the drum body 201 is parallel to the axis of the wheel 104; the inclination adjustment mechanism is adjusted according to the direction of the bisector of the angle formed by the designed longitudinal axis of the spherical bubble and the uninflated part of the sphere, so that the direction of the above-mentioned bisector is on the open plane of the drum 2 in the natural state; the second drive rotates to adjust the energy storage size of the elastic member 506 according to the buoyancy of the high-altitude balloon 8; the membrane of the high-altitude balloon 8 is passed through the drum 2 from the bottom of the drum 2 to inflate the high-altitude balloon 8; during the inflation process, check and confirm that the second slider 511 is disengaged from the gear 510; as needed, the locking release mechanism 3 is opened, and the drum 2 is quickly flipped under the combined action of the buoyancy of the high-altitude balloon 8 and the pulling force of the elastic member 506 to complete the release of the ball.

[0054] The drum 2 achieves the first energy absorption buffering when it touches the flexible member 402, and the flexible member 402 drives the third bracket 401 to rotate, compressing the second damper 403 to achieve the second energy absorption buffering. When the drum 2 flips to the specified position, the protrusion 503 collides with the third damper 404 to achieve the third energy absorption buffering.

[0055] The second slider 511 is moved so that the second slider 511 is sleeved with the gear 510, and the third driver 513 rotates, driving the reducer 512 to rotate, and then driving the second rotating shaft 501 to rotate until the drum 2 returns to the pre-release position, and the locking release mechanism is operated to lock the drum 2, and the drum 2 is rotated and reset.

[0056] The control method of the high-altitude balloon launching device provided in the embodiment of the present invention can actively adjust the launching inclination angle of the roller, thereby adapting to different inclination angles of the roller, reducing the launching risk caused by inclination mismatch, and ensuring the safe launching of high-altitude balloons.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
