Description

Technical Field

[0001] This application relates to the field of airship technology, and in particular to a ballast valve performance testing device and system. Background Technology

[0002] An airship is generally an aircraft that levitates in the air by filling its interior with a lightweight gas, relying on or primarily on atmospheric buoyancy. Airships are typically equipped with ballast, also known as a counterweight chamber. Ballast typically contains a high-density material, and releasing this material allows the airship to adjust its flight trajectory. Ballast valves are valves installed on the ballast chamber, and are generally closed most of the time. When a ballast valve is opened, the material inside the ballast chamber is released through it.

[0003] Therefore, the performance of ballast valves plays a crucial role in the safe and stable flight of airships. Related technologies typically test the performance of ballast valves by placing them in a simulated high-altitude laboratory environment and allowing materials to pass through the open valves. However, due to space limitations, the amount of material that can pass through the ballast valves is very limited, easily leading to test times that are far shorter than required, and consequently, inaccurate performance tests. Summary of the Invention

[0004] This application provides a ballast valve performance testing device and system to improve the accuracy of ballast valve performance testing.

[0005] In a first aspect, embodiments of this application provide a ballast valve performance testing device, including a storage box, a receiving box, and a driving assembly. The storage box has a first receiving cavity for containing material, and the first receiving cavity has an inlet and an outlet, with the outlet located below the inlet and used to house the ballast valve. The receiving box has a second receiving cavity with an opening located below the outlet, allowing material to enter the second receiving cavity through the outlet and the opening. The driving assembly drives the receiving box to move, causing the opening to move above the inlet, thereby allowing material in the second receiving cavity to enter the first receiving cavity through the inlet and the opening.

[0006] In some optional embodiments of this application, the feed inlet faces upward, and the driving component includes a first driving mechanism and a second driving mechanism. The first driving mechanism is fixed relative to the storage box, and the second driving mechanism is disposed at the output end of the first driving mechanism so that it can move relative to the storage box in a first direction. The receiving box is disposed at the output end of the second driving mechanism so that it can move relative to the output end of the first driving mechanism in a second direction. Of the first and second directions, one is a vertical direction so that the opening can move above the feed inlet, and the other is a horizontal direction so that the opening can be vertically opposite to the feed inlet, so that the material in the second receiving cavity can enter the first receiving cavity through the feed inlet and the opening.

[0007] In some optional embodiments of this application, the first driving mechanism is disposed at the lower end of the storage box and is arranged with the storage box along a third direction. The first direction is a horizontal direction, and both the first direction and the vertical direction are perpendicular to the third direction. The receiving box and the storage box are flush with each other in the third direction.

[0008] In some optional embodiments of this application, the receiving box and the storage box are arranged along a first direction.

[0009] In some optional embodiments of this application, the ballast valve testing device further includes a guide plate with the outlet facing downwards, the guide plate being located between the outlet and the opening, and the guide plate being offset from the receiving box in the vertical direction.

[0010] In some optional embodiments of this application, the opening faces upward, the receiving box is rotatably connected to the output end of the second drive mechanism, the axis of rotation of the receiving box relative to the second drive mechanism is parallel to a third direction, and the ballast valve performance testing device also includes a stop. During the process of the receiving box moving upward in the vertical direction, the stop can abut against the upper side of the receiving box, and the stop and the output end of the second drive mechanism are spaced apart in the first direction, so that the output end of the first drive mechanism can move in the first direction to make the receiving box rotate around the stop, thereby making the opening and the feed port face each other in the vertical direction.

[0011] In some optional embodiments of this application, the baffle extends along a first direction, with a first end of the baffle located at the middle of the feed inlet in the first direction and higher than the end wall of the feed inlet, and a second end of the baffle extending beyond the outer wall of the storage box in the first direction so as to abut against the upper side of the receiving box.

[0012] In some optional embodiments of this application, the second end of the stop is inclined downward in the vertical direction relative to the first end of the stop.

[0013] In some optional embodiments of this application, a protrusion is formed on the outer wall of the receiving box, the protrusion extends in a third direction, and during the process of the receiving box moving upward in the vertical direction, the stop abuts against the upper side of the protrusion to abut against the upper side of the receiving box.

[0014] In some optional embodiments of this application, there are multiple storage boxes and multiple receiving boxes. Each storage box has a discharge port. The multiple storage boxes and multiple receiving boxes are arranged in a one-to-one correspondence. The arrangement direction of the multiple storage boxes and the arrangement direction of the multiple receiving boxes are both third-party directions.

[0015] In some optional embodiments of this application, multiple receiving boxes are fixedly connected.

[0016] In some optional embodiments of this application, there are two driving components, multiple storage boxes are located between the two driving components along the third direction, and among the multiple receiving boxes, the receiving boxes located at both ends along the third direction are respectively disposed on the two second driving mechanisms of the two driving components.

[0017] Secondly, embodiments of this application provide a ballast valve performance testing system, including an environmental simulation chamber, a ballast valve, and a ballast valve performance testing device provided in the first aspect of this application. The interior of the environmental simulation chamber is used to simulate a high-altitude environment; the ballast valve performance testing device is disposed inside the environmental simulation chamber, and the ballast valve is disposed at the outlet.

[0018] The ballast valve performance testing device provided in this application embodiment drives the receiving box to move. This allows the receiving box to receive material released from the outlet of the storage box, and also allows the opening of the receiving box to move to a position corresponding to the inlet of the storage box, thus allowing material to be backfilled into the storage box through the opening and inlet. In this way, the material can be recycled and repeatedly passed through the ballast valve. Even with limitations in experimental space and a limited total material volume, the total time the material spends through the ballast valve is significantly increased, thereby improving the accuracy of the ballast valve performance testing.

Specifically, the use of the words "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0033] Please refer to Figure 1 and Figure 3 This application provides a ballast valve performance testing system, including an environmental simulation chamber, a ballast valve, and a ballast valve performance testing device. The interior of the environmental simulation chamber is used to simulate a high-altitude environment; the ballast valve performance testing device is located inside the environmental simulation chamber, and the ballast valve 2 is mounted on the ballast valve performance testing device.

[0034] Please refer to Figure 1 and Figure 3 In this embodiment, the ballast valve 2 is installed on a ballast valve performance testing device. The ballast valve performance testing device is used to convey material to the ballast valve 2, allowing the material to pass through the ballast valve 2, so as to test the performance of the ballast valve 2. The performance of the ballast valve 2 may include discharge speed or operational stability, etc.

[0035] Please refer to Figure 1 and Figure 3 The main working principle of ballast valve 2 is to release material in the ballast tank by opening and closing it, thereby reducing the weight of the ballast tank and the overall weight of the system. In this embodiment, ballast valve 2 is used on an aircraft. Performance testing of ballast valve 2 generally needs to be conducted in a simulated high-altitude environment within an environmental simulation chamber. A sealed space is formed inside the environmental simulation chamber, and ballast valve 2 is typically kept idle at a specified temperature and atmospheric pressure, with opening tests performed at fixed intervals. The high-altitude environment corresponds to the specific working environment of the aircraft. For example, taking a stratospheric airship, the high-altitude environment can be -50 degrees Celsius and an atmospheric density of 0 kPa. Of course, in some optional embodiments of this application, the ballast valve performance testing device may not be set up in an environmental simulation chamber, and the performance testing of ballast valve 2 may also be conducted at room temperature, depending on the type of aircraft.

[0036] Please refer to Figure 1 and Figure 3 In this embodiment, the type of aircraft to which the ballast valve 2 can be applied is not limited. For example, the aircraft can be a free balloon, a tethered balloon, an airship, a hot air balloon, or an airplane, etc. Free balloons are unpowered and drift freely with the wind; tethered balloons are unpowered and remain stationary in a predetermined position in the air via cables connected to ground facilities; while airships are powered aerostats that rely on their own power to achieve controllable maneuvering. Free balloons typically carry ballast of a certain weight inside and outside the pod. During ascent, ballast material can be thrown to accelerate the ascent speed, and during level flight, it can be thrown to increase the level flight altitude. For airships, the ballast is generally located on the belly of the airship near the bow and stern. During the ascent phase after airship launch, ballast material can be thrown to accelerate the ascent speed. During level flight, ballast material can be thrown to adjust the pitch angle or increase the level flight altitude. Airships generally include stratospheric airship ballast and low-to-medium altitude airship ballast. Ballast in stratospheric airships can adjust the airship's altitude, pitch attitude, and increase its takeoff speed; ballast in low- and medium-altitude airships plays a role in adjusting the airship's attitude.

[0037] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 The ballast valve performance testing device provided in this application includes a storage box 1, a receiving box 3, and a driving assembly 4. The storage box 1 has a first receiving cavity 11 for containing materials. The first receiving cavity 11 has an inlet 111 and an outlet, with the outlet located below the inlet 111. The outlet is used to house the ballast valve 2. The receiving box 3 has a second receiving cavity 31 with an opening 311 located below the outlet, allowing materials to enter the second receiving cavity 31 through the outlet and the opening 311. The driving assembly 4 drives the receiving box 3 to move, causing the opening 311 to move above the inlet 111, thereby allowing materials in the second receiving cavity 31 to enter the first receiving cavity 11 through the inlet 111 and the opening 311. This structural design allows the drive component 4 to move the receiving box 3. On one hand, the receiving box 3 can receive material released from the outlet of the storage box 1; on the other hand, it allows the opening 311 of the receiving box 3 to move to a position corresponding to the inlet 111 of the storage box 1, thus allowing material to be backfilled into the storage box 1 through the opening 311 and the inlet 111. In this way, the material can be recycled and repeatedly passed through the ballast valve 2. Even with limitations in experimental space and a limited total amount of material, the total time the material spends passing through the ballast valve 2 is greatly increased, improving the accuracy of performance testing of the ballast valve 2.

[0038] It is understood that the ballast valve performance testing device in this application embodiment has at least two states. Figure 1 This is a first-view structural schematic diagram of the ballast valve performance testing device in a first state in some embodiments of this application. Figure 3 This is a second-view structural schematic diagram of the ballast valve performance testing device in a first state in some embodiments of this application. Figure 5 This is a first-view structural schematic diagram of the ballast valve performance testing device in a second state in some embodiments of this application. Figure 7 This is a second-view structural schematic diagram of the ballast valve performance testing device in a second state according to some embodiments of this application. In the first state, the opening 311 is located below the discharge port, allowing material to enter the second receiving cavity 31 through the discharge port and the opening 311. In the second state, the opening 311 is located above the inlet 111, allowing material to enter the first receiving cavity 11 through the opening 311 and the inlet 111.

[0039] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 Generally, in the embodiments of this application, the opening 311 is located below the discharge port, allowing material to enter the second receiving cavity 31 through the discharge port and the opening 311. This means that the material enters the opening 311 from the discharge port under the action of gravity. The opening 311 can move to the upper side of the inlet 111, thereby allowing material in the second receiving cavity 31 to enter the first receiving cavity 11 through the inlet 111 and the opening 311. This means that the material enters the inlet 111 from the opening 311 under the action of gravity. Of course, in some optional embodiments of this application, a power mechanism, such as an impeller, can also be installed in the first receiving cavity 11 and / or the second receiving cavity 31 to provide power for the release of material.

[0040] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7In this application embodiment, the material entering the second receiving cavity 31 through the discharge port and opening 311 can be implemented in various ways. For example, in some optional embodiments of this application, the discharge port and opening 311 may be opposite each other, so that the material released from the discharge port enters the opening 311 and then enters the second receiving cavity 31. In other optional embodiments of this application, the discharge port and opening 311 may not be opposite each other, and a guide or similar component may be provided between the discharge port and opening 311, so that the material released from the discharge port is guided into the opening 311 by the guide component and then enters the second receiving cavity 31. The same principle applies to the material in the second receiving cavity 31 entering the first receiving cavity 11 through the inlet 111 and opening 311.

[0041] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 In some optional embodiments of the present invention, the opening 311 may include a first opening and a second opening. The first opening is located above the second opening, and the second opening has an opening and closing cover. When the ballast valve performance testing device is in the first state, the opening and closing cover is closed, and the first opening is located below the discharge port, allowing the material to enter the second receiving cavity 31 through the discharge port and the first opening. When the ballast valve performance testing device is in the second state, the opening and closing cover is open, and the second opening 311 is located above the feed inlet 111, allowing the material to enter the first receiving cavity 11 through the feed inlet 111 and the second opening.

[0042] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 It should be explained that in this embodiment of the application, the discharge port is located below the inlet 111, so that the material can flow from the inlet 111 to the discharge port under the action of gravity.

[0043] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 The materials used in the embodiments of this application can take many forms. For example, in some optional embodiments of this application, the materials can be iron powder or lead pellets, or liquids such as water or brine. Generally, in some optional embodiments of this application, the ballast valve 2 is used in a stratospheric airship, and the material can be iron powder.

[0044] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7In some optional embodiments of this application, the feed inlet 111 faces upward, and an observation window 12 is formed on the storage box 1. The orientation of the observation window 12 forms an angle with the vertical direction. Optionally, the orientation of the observation window 12 can be perpendicular to the vertical direction. This structural form facilitates the observation of materials inside the storage box 1 by the staff.

[0045] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 In some optional embodiments of this application, the ballast valve performance testing device further includes a valve support 8, with the ballast valve 2 disposed between the valve support 8 and the discharge port. This structural form facilitates the stable installation of the valve support 8.

[0046] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 In some optional embodiments of this application, the ballast valve performance testing device further includes a base 7, on which the storage box 1, valve support 8, and driving assembly 4 are all fixed. The base 7 is used to fix the device to the ground. With this structure, the storage box 1, valve support 8, driving assembly 4, and receiving box 3 form a whole, facilitating the movement of the ballast valve performance testing device by personnel. In some optional embodiments of this application, a handle 71 is also provided on the base 7, which further improves the ease of moving the ballast valve performance testing device. In some optional embodiments of this application, rollers or similar materials can also be provided at the bottom of the base 7 to facilitate the movement of the ballast valve performance testing device by personnel.

[0047] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 In some optional embodiments of this application, the base 7 is made of stainless steel, while the storage box 1 and the receiving box 3 are made of aluminum alloy. This structural design, where the main load-bearing components of the ballast valve performance testing device are made of stainless steel, and the less load-bearing components are made of aluminum alloy, helps to reduce weight while ensuring overall strength and reliability, and facilitates the movement of the ballast valve performance testing device.

[0048] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7In some optional embodiments of this application, the ballast valve performance testing device further includes a receiving box bracket 9, which is fixed to the base 7. With the opening 311 located below the discharge port, allowing material to enter the second receiving cavity 31 through the discharge port and opening 311, the lower side of the receiving box 3 is supported on the receiving box bracket 9. This mechanism reduces the load on the driving component 4, thus improving its lifespan. The material is typically iron powder or lead shot, which is relatively heavy, and its weight is transferred to the driving component 4 through the receiving box 3. To prevent the driving component 4 from constantly bearing a large load, the receiving box bracket 9 supports the receiving box 3, significantly improving the fatigue reliability of the driving component 4. In some optional embodiments of this application, the receiving box bracket 9 forms a receiving space, and the receiving box 3 is accommodated within this space when the receiving box bracket 9 supports the receiving box 3.

[0049] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 The driving component 4 in this application embodiment can be implemented in various forms. For example, in some optional embodiments of this application, the receiving box 3 can be mounted on a robotic arm, and the robotic arm can drive the receiving box 3 to move, so that the opening 311 moves to the upper side of the feed inlet 111, etc. Alternatively, in some optional embodiments of this application, the receiving box 3 can be mounted on a flipping mechanism. The flipping mechanism includes a driving member and a flipping rod. One end of the flipping rod is fixedly connected to the output end of the driving member, and the other end is fixedly connected to the receiving box 3. The driving member is used to drive the flipping rod to rotate. The axis of rotation of the flipping rod forms an angle with the axial direction of the flipping rod and also forms an angle with the vertical direction, so that the flipping rod can drive the opening 311 of the receiving box 3 to move to the upper side of the feed inlet 111.

[0050] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7In some optional embodiments of this application, the driving component 4 includes a first driving mechanism 41 and a second driving mechanism 42. The receiving box 3 is driven by the first driving mechanism 41 and the second driving mechanism 42, causing the opening 311 to move to the upper side of the feed port 111. Specifically, the feed inlet 111 faces upwards. The driving component 4 includes a first driving mechanism 41 and a second driving mechanism 42. The first driving mechanism 41 is fixed relative to the storage box 1. The second driving mechanism 42 is located at the output end of the first driving mechanism 41, allowing it to move relative to the storage box 1 along a first direction a. The receiving box 3 is located at the output end of the second driving mechanism 42, allowing it to move relative to the output end of the first driving mechanism 41 along a second direction b. Of the first direction a and the second direction b, one is a vertical direction, allowing the opening 311 to move above the feed inlet 111, and the other is a horizontal direction, allowing the opening 311 to be vertically aligned with the feed inlet 111, so that the material in the second receiving cavity 31 can enter the first receiving cavity 11 through the feed inlet 111 and the opening 311. With this structure, the driving component 4 can be implemented using the first driving mechanism 41 and the second driving mechanism 42. The structure of the driving component 4 is relatively simple, highly reliable, and low in cost. The feed inlet 111 faces upward, which makes it easier for the material to enter the first receiving cavity 11 through the opening 311 and the feed inlet 111. It also makes it less likely that the material will fall outside the feed inlet 111 during the process of releasing the material from the second receiving cavity 31.

[0051] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 To facilitate understanding, the movement process of the receiving box 3 driven by the first drive mechanism 41 and the second drive mechanism 42 is described below. During the movement of the receiving box 3 driven by the drive assembly 4, the drive assembly 4 can first drive the receiving box 3 to move vertically, allowing the opening 311 to move above the feed inlet 111; then, the drive assembly 4 drives the receiving box 3 to move horizontally, so that the feed inlet 111 and the opening 311 are vertically aligned. This allows for a more streamlined structure of the drive assembly 4, higher reliability, and lower cost.

[0052] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7The first drive mechanism 41 and the second drive mechanism 42 in this application can be implemented in various ways. For example, in some optional embodiments of this application, the first drive mechanism 41 and / or the second drive mechanism 42 can be implemented as a worm gear mechanism. Exemplarily, the first drive mechanism 41 is a worm gear mechanism, where the worm's axis can be horizontal or vertical. The worm is the output end of the first drive mechanism 41, and the second drive mechanism 42 is fixed to the worm. The worm gear mechanism has a large transmission ratio and is suitable for scenarios with large loads. The receiving box 3 contains materials with high density, typically weighing around 20 kilograms. Therefore, using a worm gear mechanism to drive the movement of the receiving box 3 is quite suitable.

[0053] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 For example, in some optional embodiments of this application, the first drive mechanism 41 and / or the second drive mechanism 42 can also be implemented by a belt drive mechanism. The movement of the belt drive mechanism is relatively smooth, which is beneficial to reduce vibration. Under large load, reducing vibration can significantly improve the reliability of the structure.

[0054] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 For example, in some optional embodiments of this application, the first drive mechanism 41 and / or the second drive mechanism 42 can be implemented using a lead screw and nut mechanism. Exemplarily, the first drive mechanism 41 is a lead screw and nut mechanism, where the axis of the lead screw can be horizontal or vertical, the nut is the output end of the first drive mechanism 41, and the nut is helically connected to the lead screw. The second drive mechanism 42 is fixed to the nut. The lead screw and nut mechanism provides relatively smooth movement, strong load capacity, and relatively low cost, making it suitable for driving the material receiving box 3. Of course, in some other optional embodiments of this application, the first drive mechanism 41 and / or the second drive mechanism 42 can be implemented using a linkage slider mechanism, a gear and rack mechanism, or a chain drive mechanism, etc.

[0055] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7In some optional embodiments of this application, the first drive mechanism 41 is disposed at the lower end of the storage box 1 and arranged along a third direction c with the storage box 1. The first direction a is horizontal, and both the first direction a and the vertical direction are perpendicular to the third direction c. The receiving box 3 is flush with the storage box 1 along the third direction c. In this structural form, the first direction a is horizontal, which is conducive to the stable installation of the first drive mechanism 41 and makes the load-bearing capacity of the drive component 4 on the discharge box more stable. The flush arrangement of the receiving box 3 and the storage box 1 along the third direction c helps to improve the compactness of the structure and reduce the space occupied by the ballast valve performance testing device.

[0056] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 It should be explained that the receiving box 3 and the storage box 1 are flush in the third direction c: the opening 311 is located below the discharge port, so that the material can enter the second receiving cavity 31 through the discharge port and the opening 311. In this case, the receiving box 3 and the storage box 1 are flush in the third direction c.

[0057] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 Of course, in some other optional embodiments of this application, the first direction a may be vertical. Specifically, the first driving mechanism 41 is disposed at the lower end of the storage box 1 and is arranged with the storage box 1 along the third direction c. The first direction a is vertical, and the second direction b is perpendicular to both the vertical direction and the third direction c. The receiving box 3 is flush with the storage box 1 along the third direction c.

[0058] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 In some optional embodiments of this application, the receiving box 3 and the storage box 1 are arranged along the first direction a. With this structure, when the receiving box 3 moves vertically under the driving force of the driving component 4, the receiving box 3 will not interfere with the storage box 1. This simplifies the movement process of the receiving box 3 and simplifies the structure of the first driving mechanism 41 and the second driving mechanism 42.

[0059] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7To facilitate understanding, the movement process of the receiving box 3 driven by the driving component 4 is described below. During this movement, the driving component 4 first moves the receiving box 3 vertically, allowing the opening 311 to move above the feed inlet 111. Since the receiving box 3 and the storage box 1 are arranged along the first direction a, the receiving box 3 will not interfere with the storage box 1 during its vertical movement driven by the driving component 4. Then, the driving component 4 moves the receiving box 3 horizontally, bringing the feed inlet 111 and the opening 311 vertically opposite each other. This design allows for a more streamlined structure, higher reliability, and lower cost for the driving component 4.

[0060] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 It should be explained that the arrangement of receiving box 3 and storage box 1 along the first direction a means that: when the opening 311 is located below the discharge port, so that the material can enter the second receiving cavity 31 through the discharge port and the opening 311, the receiving box 3 and storage box 1 are arranged along the first direction a.

[0061] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 Based on the arrangement of the receiving box 3 and the storage box 1 along the first direction a, in some optional embodiments of this application, the ballast valve 2 performance testing device further includes a guide plate 5. The discharge port faces downward, and the guide plate 5 is located between the discharge port and the opening 311, and the guide plate 5 is vertically offset from the receiving box 3. With this structure, based on the arrangement of the receiving box 3 and the storage box 1 along the first direction a, the material released from the discharge port can smoothly enter the second receiving cavity 31 through the opening 311, and the structure is relatively simple and easy to install. The vertical offset of the guide plate 5 from the receiving box 3 ensures that the guide plate 5 will not interfere with the receiving box 3 during its upward vertical movement. Understandably, in order to ensure that the material released from the discharge port smoothly enters the second receiving cavity 31 through the opening 311, the first end of the guide plate 5 is disposed at the lower end of the discharge port and is disposed opposite to the discharge port in the vertical direction, and the second end is disposed close to the opening 311 and is inclined downward in the vertical direction relative to the first end. In some optional embodiments of this application, in order to facilitate the smooth passage of material through the opening 311 into the second receiving cavity 31, the second end of the guide plate 5 is higher than or flush with the opening 311 in the vertical direction.

[0062] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7It should be explained that the guide plate 5 being located between the discharge port and the opening 311 means that the opening 311 is located below the discharge port, and the guide plate 5 is located between the discharge port and the opening 311 to allow the material to enter the second receiving cavity 31 through the discharge port and the opening 311.

[0063] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 Of course, in some alternative embodiments of this application, the receiving box 3 and the storage box 1 may not be arranged along the first direction a. The receiving box 3 may be located below the storage box 1 in the vertical direction so that the material released from the outlet can enter the opening 311 and then enter the second receiving cavity 31. During the process of the driving component 4 driving the receiving box 3 to move, the first driving mechanism 41 first drives the receiving box 3 to move, so that the receiving box 3 and the storage box 1 are arranged along the first direction a. Then, the second driving mechanism 42 drives the receiving box 3 to move upward to above the inlet 111. In this way, the receiving box 3 and the storage box 1 will not interfere with each other in the vertical direction. Finally, the first driving mechanism 41 drives the receiving box 3 to move in the opposite direction, so that the receiving box 3 is close to the storage box 1, so that the material released from the opening 311 can smoothly enter the inlet 111 and then smoothly enter the first receiving cavity 11.

[0064] Please refer to Figure 2 , Figure 4 and Figure 6In some optional embodiments of this application, the opening 311 faces upward, the receiving box 3 is rotatably connected to the output end of the second drive mechanism 42, and the axis of rotation of the receiving box 3 relative to the second drive mechanism 42 is parallel to the third direction c. The ballast valve performance testing device also includes a stop 6. During the upward movement of the receiving box 3 in the vertical direction, the stop 6 can abut against the upper side of the receiving box 3, and the stop 6 and the output end of the second drive mechanism 42 are spaced apart in the first direction a, so that the movement of the output end of the first drive mechanism 41 in the first direction a can cause the receiving box 3 to rotate around the stop 6, thereby making the opening 311 and the feed inlet 111 vertically opposite each other. In some other optional embodiments of this application, the position where the receiving box 3 is rotatably connected to the output end of the second drive mechanism 42 is located at the middle of the opening 311 along the first direction a. With this structural form, during the movement of the receiving box 3 driven by the driving component 4, one end abuts against the stop 6 and rotates, so that the opening 311 and the feed inlet 111 are vertically aligned. This is relatively convenient and does not require an additional rotary drive mechanism such as a rotary motor, which simplifies the structure of the driving component 4. Moreover, since the receiving box 3 contains materials and has a large load, the rotation caused by abutting against the stop 6 ensures high reliability. In some other optional embodiments of this application, the receiving box 3 can also be driven to rotate relative to the second drive mechanism 42 by a rotary drive component such as a rotary motor, so that the opening 311 and the feed inlet 111 are vertically aligned.

[0065] In some optional embodiments of this application, the baffle 6 extends along the first direction a, with its first end located at the center of the feed inlet 111 in the first direction a and higher than the end wall of the feed inlet 111. The second end of the baffle 6 extends beyond the outer wall of the storage box 1 in the first direction a, so as to abut against the upper side of the receiving box 3. This structure facilitates the smooth passage of material through the opening 311 into the first receiving cavity 11 during the rotation of the receiving box 3 relative to the second drive mechanism 42.

[0066] In some optional embodiments of this application, the second end of the stop 6 is inclined downward in the vertical direction relative to the first end of the stop 6. With this structure, as the receiving box 3 moves upward, the stop 6 guides the movement of the receiving box 3, causing the receiving box 3 to move in the first direction a toward the storage box 1.

[0067] In some optional embodiments of this application, a protrusion 32 is formed on the outer wall of the receiving box 3. The protrusion 32 extends along a third direction c. During the upward movement of the receiving box 3 in the vertical direction, the stop 6 abuts against the upper side of the protrusion 32, thereby abutting against the upper side of the receiving box 3. With this structure, the receiving box 3 abuts against the stop 6 through the protrusion 32 extending along the third direction c. During the rotation of the receiving box 3 around the stop 6, the abutment between the protrusion 32 and the stop 6 will be relatively tight. In some optional embodiments of this application, the protrusion 32 and the feed inlet 111 are arranged along the third direction c. Based on this, in some optional embodiments of this application, the protrusion 32 is located at the end of the feed inlet 111 along the first direction a.

[0068] In some optional embodiments of this application, the stop 6 includes a first bent portion 61 and a second bent portion 62. The first bent portion 61 is formed on the side wall of the feed inlet 111, and the second bent portion 62 is formed at the end of the first bent portion 61. This structural form facilitates the processing and manufacturing of the stop 6.

[0069] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 In some optional embodiments of this application, there are multiple storage boxes 1 and multiple receiving boxes 3. Each storage box 1 has a discharge port, and the multiple storage boxes 1 and multiple receiving boxes 3 are arranged in a one-to-one correspondence. The arrangement direction of the multiple storage boxes 1 and the arrangement direction of the multiple receiving boxes 3 are both in the third direction c. With this structural form, the ballast valve performance testing device can test multiple ballast valves 2 independently and simultaneously without interference, which can greatly improve the testing efficiency. The arrangement direction of the multiple storage boxes 1 and the arrangement direction of the multiple receiving boxes 3 in the third direction c is conducive to a more compact structure and reduces the space occupied.

[0070] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 In some optional embodiments of this application, the ballast performance testing device includes a receiving box and multiple partitions. The partitions are all disposed within the inner cavity of the receiving box and are spaced apart along a third direction c to divide the inner cavity of the receiving box into multiple first receiving cavities 11 or second receiving cavities 31. This structural configuration makes it convenient to implement multiple storage boxes 1 or receiving boxes 3, resulting in a more compact structure.

[0071] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7In some optional embodiments of this application, multiple receiving boxes 3 are fixedly connected. There are two driving components 4. Along the third direction c, multiple storage boxes 1 are located between the two driving components 4. Among the multiple receiving boxes 3, the receiving boxes 3 located at both ends along the third direction c are respectively disposed on the two second driving mechanisms 42 of the two driving components 4. With this structural configuration, multiple storage boxes 1 are fixed together and moved by the two driving components 4. The structure of the driving components 4 is relatively simple, has low implementation cost, and high reliability.

[0072] Furthermore, since the first drive mechanism 41 is a lead screw and nut mechanism, the two drive components 4 are arranged along the third direction c, which can also prevent the storage box 1 from rotating with the lead screw. This eliminates the need for additional guide rails or similar components that extend along the lead screw axis, making the structure of the drive component 4 more streamlined.

[0073] The above are merely preferred embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
