[0002] A floating vehicle is an aircraft that relies on buoyancy to stay aloft, and its specific gravity is usually lighter than air. Based on whether there is power, the floating vehicle can be divided into two categories: airships and high-altitude balloons. Among them, the high-altitude balloon flies by using the buoyancy generated by the gas with a density less than air, without the need to provide power.

[0041] A lighter-than-air aircraft is an aircraft that relies on the lift of the surrounding air for lift. Lighter-than-air aircraft can be classified as either a dirigible or a high-altitude balloon. A high-altitude balloon is a low-dynamic aircraft in the near space that flies using the lift of a gas that is less dense than air. The high-altitude balloon has the characteristics of high flight altitude, low speed, and large load. The high-altitude balloon is usually used as a reliable platform for high-altitude scientific experiments. A dirigible is a lighter-than-air aircraft that usually includes a gondola, an energy system, a propulsion system, a payload cabin, a bow, a stern, a ballast structure, and a control system. The dirigible usually carries several tons of payload and has the ability of fixed-point control, active control, and maneuvering. The dirigible relies on static lift to stay in the air and is powered by solar energy. The flight altitude of the dirigible is usually between 20 km and 30 km.

[0042] In the related art, a ballast structure is usually arranged on the lighter-than-air aircraft. The ballast structure is usually arranged at the position close to the bow and the stern of the lighter-than-air aircraft in the abdomen of the lighter-than-air aircraft. The ballast structure stores a certain amount of material. During the flight of the lighter-than-air aircraft, the ballast structure can adjust the pitch angle of the lighter-than-air aircraft by discharging the material at the bow or the stern of the lighter-than-air aircraft. Before the ballast structure is put into use, the ballast structure needs to be tested. However, the ballast structure is prone to dumping during the test. Therefore, it is urgent to provide a ballast structure test tool to reduce the probability of dumping of the ballast structure during the test.

[0043] To solve the above problems, with reference to Figure 1 and Figure 2 the embodiment of the present application provides a ballast structure test tool. The ballast structure test tool includes a supporting assembly 1 and a side stop piece 2. The supporting assembly 1 includes a support structure 11 and a supporting piece 12 arranged on the support structure 11. The supporting piece 12 has a supporting part 121 for supporting the ballast structure 5. The side stop piece 2 is arranged on the supporting piece 12 and surrounds the circumference of the supporting part 121 to stop the ballast structure 5.

[0044] The ballast structure test tool provided in the embodiment of the present application comprises a supporting assembly 1 and a side stop 2, wherein the supporting assembly 1 comprises a supporting structure 11 and a supporting piece 12 arranged on the supporting structure 11, the supporting structure 11 provides support for the supporting piece 12, and the supporting piece 12 is provided with a supporting portion 121; the side stop 2 is arranged on the supporting piece 12 and surrounds the circumference of the supporting portion 121. When the ballast structure 5 is tested, the ballast structure 5 can be placed on the supporting portion 121 of the supporting piece 12, so that the supporting portion 121 can provide support for the ballast structure 5, and the side stop 2 can provide limiting for the ballast structure 5 in the circumferential direction of the supporting portion 121, thereby reducing the probability of the ballast structure 5 from falling down during the test. In summary, the ballast structure test tool provided in the embodiment of the present application can reduce the probability of the ballast structure 5 from falling down during the test.

[0045] In the embodiment of the present application, the side stop 2 provides limiting for the ballast structure 5 in the circumferential direction of the supporting portion 121, therefore, the structure design of the side stop 2 has multiple possibilities, for example, the side stop 2 can be a block structure, a rod structure or a plate structure, and the present application does not limit this.

[0046] With reference to Figure 7 In the embodiment of the present application, the ballast structure 5 comprises a storage tank 51 and a discharge assembly 52, in the height direction of the ballast structure 5, the storage tank 51 is formed by splicing a cylindrical tank body located at the upper portion and a conical tank body located at the lower portion, the discharge port of the storage tank 51 is located at the bottom of the conical tank body, and the discharge assembly 52 is arranged at the discharge port of the storage tank 51. The bottom of the conical tank body and the discharge assembly 52 jointly form a discharge portion of the ballast structure 5, and the remaining part of the storage tank 51 forms a storage portion of the ballast structure 5.

[0047] With reference to Figure 1 and Figure 6 In the embodiment of the present application, the supporting piece 12 is further provided with an avoiding portion 122, the avoiding portion 122 is used for avoiding the discharge portion on the ballast structure 5, the supporting structure 11 is provided with an accommodating space, and in the gravity direction, the accommodating space is arranged in position with the avoiding portion 122, so as to accommodate the discharge portion on the ballast structure 5. In this way, with reference to Figure 7 When the ballast structure 5 is placed on the supporting portion 121 of the supporting piece 12, the supporting piece 12 can provide support for the storage portion of the ballast structure 5, the discharge portion on the ballast structure 5 can pass through the avoiding portion 122 on the supporting piece 12 and enter the accommodating space on the supporting structure 11, so that the discharge portion on the ballast structure 5 is arranged lower than the supporting portion 121, the height of the ballast structure 5 when placed on the supporting piece 12 is reduced, the center of gravity of the ballast structure 5 and the ballast structure test tool as a whole is lowered, and the probability of the ballast structure 5 from falling down during the test is further reduced.

[0048] In the embodiment, the structure of the supporting part 121 has multiple possibilities. For example, the supporting part 121 can include a supporting fulcrum, and when the ballast structure 5 is placed on the supporting part 121, the supporting fulcrum can be in point contact with the ballast structure 5. For example, the supporting part 121 can include a supporting surface, and when the ballast structure 5 is placed on the supporting part 121, the supporting surface can be in surface contact with the ballast structure 5. Figure 1 Figure 6 In an implementation provided by the embodiment, the supporting part 121 is a supporting surface, and the supporting surface surrounds the avoiding part 122. Here, the supporting part 121 is a supporting surface, which can increase the contact area between the supporting part 121 and the ballast structure 5, thereby reducing the risk of damage to the ballast structure 5 due to excessive local stress. The supporting surface surrounds the avoiding part 122, so that the supporting surface can provide support for the ballast structure 5 in the circumferential direction of the avoiding part 122, thereby enhancing the stability of the ballast structure 5 at the supporting part 121.

[0049] In the embodiment, the structure of the supporting surface has multiple possibilities. For example, the supporting surface can be a plane, or an arc surface, which is not limited in the embodiment. For example, the supporting surface can be a plane, and when the ballast structure 5 is placed on the supporting part 121, the supporting surface can be in surface contact with the ballast structure 5. Figure 1 Figure 6 In an implementation provided by the embodiment, the supporting surface is a tapered surface, and in the direction of gravity, the radial dimension of the supporting surface gradually decreases. For example, the supporting surface can be a tapered surface, and in the direction of gravity, the radial dimension of the supporting surface gradually decreases. Figure 7 The tank body below the storage part of the storage tank 51 is conical. Here, the supporting surface is designed as a tapered surface, which can make the supporting surface completely fit the outer wall surface of the storage part of the storage tank 51 when the ballast structure 5 is placed on the supporting part 121. In this way, the supporting surface can provide a limit for the storage tank 51 in the circumferential direction, thereby further enhancing the stability of the ballast structure 5 at the supporting part 121.

[0050] For example, the supporting part 121 can include a supporting surface, and when the ballast structure 5 is placed on the supporting part 121, the supporting surface can be in surface contact with the ballast structure 5. Figure 1 Figure 6 In the embodiment, the supporting part 121 is provided with a cable avoiding opening 123, and the cable avoiding opening 123 is used to avoid the cables on the ballast structure 5. In this way, when the ballast structure 5 is placed on the supporting part 121 of the supporting member 12, the cables on the outer surface of the ballast structure 5 can be arranged through the cable avoiding opening 123, thereby avoiding damage to the cables on the outer surface of the ballast structure 5 due to extrusion.

[0051] In the embodiment, the supporting structure 11 is used to provide support for the supporting member 12, and therefore, the structure of the supporting structure 11 has multiple possibilities. For example, the supporting structure 11 can include a supporting block, and one side of the supporting block has a fixing position for fixing the supporting member 12, and the supporting member 12 is fixed at the fixing position. Meanwhile, the inside of the supporting block can be processed to form an accommodating cavity, and the accommodating cavity forms an accommodating space for accommodating the discharge part on the ballast structure 5. Figure 1 ​​​In an implementation provided by the embodiment of the present application, the support structure 11 comprises at least three support members 111, the at least three support members 111 are fixedly connected with the supporting member 12, and the at least three support members 111 are arranged at intervals in the circumferential direction of the supporting member 12. Here, the support structure 11 comprises at least three support members 111, so that the structure of the support structure 11 can be simplified, and the weight of the support structure 11 can be reduced, thereby facilitating the processing and movement of the ballast structure test tool. The at least three support members 111 are fixedly connected with the supporting member 12, and the at least three support members 111 are arranged at intervals in the circumferential direction of the supporting member 12. In this way, in the circumferential direction of the supporting member 12, the support members 111 can provide reliable support for the supporting member 12, thereby improving the reliability of the ballast structure test tool in use. In addition, the accommodation cavity can be collectively surrounded by the support members 111, so that the accommodation cavity does not need to be independently processed on the support structure 11, thereby reducing the production process of the support structure 11, and thereby reducing the production cost of the support structure 11.

[0052] In the embodiment of the present application, the arrangement mode of the support member 111 has multiple possibilities, for example, the support member 111 can be arranged vertically along the direction of gravity. Referring to Figure 1 、 Figure 2 and Figure 6 In an implementation provided by the embodiment of the present application, the support member 111 has oppositely arranged connecting end 1111 and support end 1112, the connecting end 1111 is fixedly connected with the supporting member 12, and in the direction of gravity, the at least three support members 111 are all arranged obliquely, so that the support ends 1112 on the at least three support members 111 are away from each other. Here, the support member 111 has oppositely arranged connecting end 1111 and support end 1112, the connecting end 1111 is fixedly connected with the supporting member 12, so that the support member 111 provides support for the supporting member 12. In the direction of gravity, the at least three support members 111 are all arranged obliquely, so that the support ends 1112 on the at least three support members 111 are away from each other. In this way, the height of the supporting member 12 can be reduced. When the ballast structure 5 is placed on the supporting member 12, the center of gravity of the ballast structure 5 and the ballast structure test tool as a whole can be further reduced, thereby reducing the probability of the ballast structure 5 falling during the test process.

[0053] In the embodiment of the present application, the number of support members 111 has multiple possibilities, for example, the number of support members 111 can be three, four or six, and the embodiment of the present application does not limit this. Referring to Figure 1 、 Figure 2 and Figure 6 In an implementation provided by the embodiment of the present application, the number of support members 111 is four.

[0054] In the embodiments of the present application, the side stopper 2 can be arranged on the supporting member 12 in various ways. For example, the side stopper 2 can be directly arranged on the supporting member 12. Referring to Figure 1 , Figure 2 and Figure 6 In an implementation provided by the embodiments of the present application, the side stopper 2 is formed by extending the connecting end 1111 of the support member 111, and the side stopper 2 is indirectly arranged on the supporting member 12 through the support member 111. In this way, the production process of the ballast structure test tool can be further reduced, thereby reducing the production cost of the ballast structure test tool.

[0055] In the embodiments of the present application, the ballast structure test tool further comprises a locking structure arranged on the supporting assembly 1 to fix the ballast structure 5. In this way, when the ballast structure 5 is placed on the supporting portion 121 of the supporting member 12, the ballast structure 5 can be fixed by the locking structure to avoid falling off the supporting member 12, thereby further improving the reliability of the ballast structure test tool in use.

[0056] In the embodiments of the present application, the locking structure is used to fix the ballast structure 5, and therefore the locking structure can have various structural forms. For example, the locking structure can comprise a clamping hook, and the outer wall surface of the ballast structure 5 is provided with a clamping groove matched with the clamping hook. When the ballast structure 5 is placed on the supporting portion 121 of the supporting member 12, the clamping hook can be engaged with the clamping groove on the ballast structure 5 to fix the ballast structure 5. Alternatively, the locking structure can comprise a locking hole and a locking pin, and the outer wall surface of the ballast structure 5 is provided with a fixing member having a fixing hole. When the ballast structure 5 is placed on the supporting portion 121 of the supporting member 12, the fixing hole on the ballast structure 5 can be aligned with the locking hole on the supporting assembly 1, and the locking pin can pass through the fixing hole and the locking hole in sequence to fix the ballast structure 5.

[0057] In the embodiments of the present application, the locking structure can be arranged on the supporting structure 11 or the supporting member 12, and the embodiments of the present application do not limit the arrangement position of the locking structure on the supporting assembly 1.

[0058] Referring to Figure 1 , Figure 2 and Figure 6In the embodiment, the ballast structure test tool further comprises a test structure 3 arranged on the supporting assembly 1. The test structure 3 comprises a material collecting member 31 for collecting the material discharged from the ballast structure 5. In this way, after the ballast structure 5 is placed on the supporting part 121 of the supporting member 12, the material discharging part on the ballast structure 5 can be opened, and the material collecting member 31 can be used to collect the material discharged from the ballast structure 5, so as to test whether the material of the ballast structure 5 is discharged smoothly. In addition, the test structure 3 is arranged on the supporting assembly 1, so that the test structure 3 can move synchronously with the ballast structure 5, the probability of the test structure 3 being overturned due to the change of the posture of the ballast structure 5 is reduced, the test process of the ballast structure 5 is not easily interrupted, and the continuity of the test of the ballast structure 5 is facilitated.

[0059] In the embodiment, the test structure 3 further comprises at least one of a weighing unit 32 and a flow rate test unit. The weighing unit 32 is used to measure the weight of the material in the material collecting member 31, and the flow rate test unit is used to detect the flow rate of the material discharged from the ballast structure 5. In this way, when the ballast structure 5 is tested whether the material is discharged smoothly, the weighing unit 32 can be used to measure the weight of the material in the material collecting member 31 in real time, and the flow rate test unit can be used to detect the flow rate of the material discharged from the ballast structure 5 in real time, so as to achieve the purpose of measuring whether the ballast structure 5 works normally and whether the performance index meets the standard.

[0060] In the embodiment, the flow rate test unit is used to detect the flow rate of the material discharged from the ballast structure 5, and therefore, the structure of the flow rate test unit has multiple possibilities. For example, the flow rate test unit can be a velocity measuring tube, a orifice flowmeter, or a laser speedometer, and the embodiment is not limited in this regard.

[0061] In the embodiment, the weighing unit 32 is used to measure the weight of the material in the material collecting member 31, and therefore, the structure of the weighing unit 32 has multiple possibilities. For example, the weighing unit 32 can be a pressure device, a force sensor, or a capacitive sensor, and the embodiment is not limited in this regard.

[0062] In the embodiment, the structure of the test structure 3 has multiple possibilities. For example, the test structure 3 can only comprise the weighing unit 32, or only comprise the flow rate test unit, or simultaneously comprise the weighing unit 32 and the flow rate test unit, and the embodiment is not limited in this regard. For example, Figure 3 and Figure 5 In a possible embodiment of the application, the test structure 3 simultaneously comprises the weighing unit 32 and the flow rate test unit (not shown in the figure).

[0063] For example, Figure 3 and Figure 4In the embodiment, the material collecting member 31 comprises a material storage box 311 and a cover plate 312. The material storage box 311 has a material storage cavity for accommodating material. The cover plate 312 has a feeding port 3121, and the cover plate 312 is arranged on the material storage box 311. When the material collecting member 31 collects material, the cover plate 312 can shield the splashed material to prevent the splashed material from flying out of the material storage cavity, thereby improving the test accuracy of the test structure 3.

[0064] With reference to Figure 3 and Figure 5 In the embodiment, the test structure 3 further comprises a measurement base 33. The measurement base 33 has an installation cavity. The bottom of the installation cavity is provided with a guide hole 331. The material collecting member 31 is installed in the installation cavity, and the bottom of the material collecting member 31 is provided with a guide column 313 which is movably connected with the guide hole 331. The weighing unit 32 is arranged at the bottom of the installation cavity to measure the weight of the material in the material collecting member 31. In addition, in order to intuitively display the test results, the test structure 3 can comprise a processor 34 and a display screen 35. The processor 34 is arranged at the bottom of the installation cavity. The weighing unit 32 and the flow rate test unit are electrically connected with the processor 34 to respectively transmit test data to the processor 34. After the processor 34 processes the test data, the processor 34 transmits the test results of the weighing unit 32 and the flow rate test unit to the display screen 35 for display. Figure 5 In the embodiment, the test structure 3 can be arranged on the support assembly 1 in various ways. For example, the support assembly 1 can comprise a mounting shell which is fixedly arranged on the support structure 11. The mounting shell has an installation cavity in which the test structure 3 is arranged. Figure 1 and Figure 6 In one implementation provided in the embodiment, the support assembly 1 can comprise a mounting bracket 13 and a mounting plate 14. The mounting bracket 13 comprises mounting rods which are arranged in a staggered manner. The ends of the mounting rods are fixedly connected with the support member 111. The mounting plate 14 is fixed on the mounting bracket 13 and has mounting positions for placing the test structure 3. In this way, the mounting bracket 13 can support the mounting plate 14 and enhance the structural strength of the support structure 11, thereby improving the reliability of the ballast structure test tool in use. The mounting plate 14 is fixed on the mounting bracket 13 and has mounting positions for placing the test structure 3.
