Description

Technical Field

[0001] This utility model relates to the field of rotor connection technology, and in particular to a rotor connection structure for amphibious equipment. Background Technology

[0002] The most widely recognized accurate flow measurement methods in the hydrological industry today are rotor current meters and mobile ADCP measurement methods. Other measurement methods are usually compared with these to verify the accuracy of the data. Among them, the most common are rotor current meter measurement and mobile ADCP measurement. However, neither of these methods is suitable for measuring water flow at medium and high water levels. Therefore, amphibious equipment is used for measurement. The rotor installation in traditional amphibious equipment usually adopts rigid installation or simple spring damping. Although the rigid installation structure can ensure transmission efficiency, it lacks buffer protection. When encountering sudden impacts such as wind and waves, the impact force will be directly transmitted to the precision transmission gears and motors without any attenuation, which can easily cause irreversible damage. Utility Model Content

[0003] The purpose of this invention is to provide a rotor connection structure for amphibious equipment to solve the problems mentioned in the background art.

[0004] The technical problem solved by this utility model is achieved through the following technical solution:

[0005] A rotor connection structure for amphibious equipment includes a middle sleeve and a top cover connection. A bidirectional power transmission unit is installed in the inner cavity of the middle sleeve. The power output ends of the upper and lower ends of the bidirectional power transmission unit are respectively connected to drive disks. A vertical movable component is provided between the top cover connection and the drive disks. Inner annular grooves are respectively provided at the upper and lower ends of the inner cavity of the middle sleeve. An elastic connection part is fixedly installed on the top cover connection part. The elastic connection part is slidably connected in the inner annular groove. An elastic buffer part is installed on the protruding part at the bottom edge of the elastic connection part. The top cover connection part can slide up and down while ensuring the transmission of rotational power through the vertical movable component, and the elastic buffer part provides buffer protection.

[0006] Preferably, the vertically movable component includes a raised ring fixedly mounted on the drive disk. A plurality of sliding grooves are evenly distributed in the inner cavity of the raised ring. A retaining ring is slidably mounted in the inner cavity of the raised ring. The protrusion of the retaining ring is slidably embedded in the corresponding sliding groove. A connecting part is fixedly mounted at the bottom of the top cover connecting part. The connecting part is fixedly connected to the retaining ring.

[0007] Preferably, the middle sleeve is provided with a connecting part, in which a power transmission shaft is installed. One end of the power transmission shaft is connected to the power input end of the bidirectional power transmission unit, and the other end is connected to the power source to realize power transmission.

[0008] Preferably, the elastic connection portion has a break in the middle, which divides the elastic connection portion into two parts.

[0009] Preferably, a rotor is fixedly connected to the top cover connecting part.

[0010] The advantages and positive effects of this utility model are:

[0011] This invention, through the synergistic effect of the vertically movable component and the elastic buffer, allows the rotor assembly to perform controllable upward displacement and sliding during the impact of wind and waves. This transforms the enormous rigid impact into the deformation of the elastic buffer to absorb and dissipate energy. This design effectively prevents the impact force from being directly transmitted to the core transmission system and power source, preventing damage to them. At the same time, the power transmission path remains engaged throughout the entire process, ensuring the equipment's emergency response capability. After the impact, the system can automatically reset without external intervention, significantly improving the equipment's reliability, survivability, and ease of maintenance in complex hydrological environments.

However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the utility model will be more thorough and complete.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of at least two components or the interaction relationship of at least two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. The embodiments of this invention are further described in detail below with reference to the accompanying drawings:

[0022] Please see Figure 1-5An embodiment of this utility model includes an amphibious equipment body 25, with power chambers 24 located at the four corners of the body 25. A rotor for takeoff is installed in each power chamber 24. The amphibious equipment body 25 includes a middle sleeve 12, a power transmission shaft 10, and a rotor 14. A bidirectional power transmission unit 16 is installed in the inner cavity of the middle sleeve 12. Drive disks 17 are connected to the upper and lower power output ends of the bidirectional power transmission unit 16. A vertical movable component is provided between the top cover connecting part 13 and the drive disk 17. Inner annular grooves 15 are provided at the upper and lower ends of the inner cavity of the middle sleeve 12. An elastic connecting part 21 is fixedly installed on the top cover connecting part 13. The connecting part 21 is slidably connected in the inner annular groove 15. An elastic buffer part 22 is installed on the protruding bottom edge of the elastic connecting part 21. The top cover connecting part 13 can slide up and down while ensuring the transmission of rotational power through the vertical movable component, and the elastic buffer part 22 provides buffer protection. A rotor 14 is fixedly connected to the top cover connecting part 13. A connecting part 11 is provided on the middle sleeve 12. The power transmission shaft 10 is installed in the connecting part 11. One end of the power transmission shaft 10 is connected to the power input end of the bidirectional power transmission part 16, and the other end is connected to the built-in power source of the amphibious equipment body 25 to realize power transmission.

[0023] In another embodiment, the vertically moving component includes a raised ring 18 fixedly mounted on the drive disk 17. A plurality of sliding grooves 20 are evenly distributed within the inner cavity of the raised ring 18. A retaining ring 19 is slidably mounted within the inner cavity of the raised ring 18, with its protrusion slidably embedded into the corresponding sliding groove 20. A connecting part is fixedly mounted at the bottom of the top cover connecting part 13, and the connecting part is fixedly connected to the retaining ring 19. This allows the top cover connecting part 13 to have a certain degree of mobility when encountering wind and waves, effectively protecting the rotor 14.

[0024] In another embodiment, the elastic connecting part 21 is provided with a break in the middle, which divides the elastic connecting part 21 into two parts, thereby facilitating the installation of the elastic connecting part 21 into the inner ring groove 15 and making it easy to disassemble. It can be installed into the inner ring groove 15 simply by squeezing and deforming the two sides of the elastic connecting part 21 towards the middle.

[0025] In practice, the amphibious equipment was tasked with collecting hydrological data on a wide river with a fast current and occasional waves. The equipment took off from the shore, flew to the predetermined flow measurement section, landed on the water, and switched to the water operation mode. At this time, the rotor stopped working and retracted into the power chamber 24. The equipment floated with the water flow and carried out measurements. During the measurement process, a strong gust of wind stirred up a wave, which directly hit the top cover (i.e., the top cover connection part 13) of the power chamber 24 on one side of the equipment (e.g., the left front side), causing a violent upward impact on the rotor 14 assembly at that location.

[0026] The impact force of the wave acts directly on the top cover connection part 13 of the left front power chamber. The huge upward impact force is instantly transmitted through the top cover connection part 13 to the connection part fixedly connected to its bottom, thereby pushing the retaining ring 19.

[0027] The protrusion on the retaining ring 19 slides rapidly upward along the track of the groove 20 in the protruding ring portion 18. This causes the entire top cover connecting portion 13 and the rotor 14 fixed thereto to overcome the initial preload of the elastic buffer portion 22 and begin to move upward as a whole.

[0028] This is the most critical first-level energy absorption protection. The entire mechanism does not choose to "toughen" the impact force, but allows it to undergo controllable displacement. If it were designed as a completely rigid connection, the huge impact force would be directly transmitted to the bidirectional power transmission unit 16, the power transmission shaft 10, and even the core power source inside the machine body, which could easily lead to gear breakage, shaft bending, or motor damage. This step releases most of the direct impact energy by "yielding", protecting the core transmission system and power source.

[0029] Because the retaining ring 19 engages with the drive disc 17 via the groove 20, the rotational power of the drive disc 17 can still be transmitted to the top cover connection 13 and the rotor 14 even during the upward sliding process. This means that if the equipment needs to take off urgently after being impacted, the power transmission is not interrupted (although the rotor may not be in its original working position at this time).

[0030] As the top cover connecting part 13 moves upward, the elastic connecting part 21 fixed thereon also slides upward in the inner ring groove 15. When the displacement reaches a certain range, the elastic buffer part 22 (which can be understood as a buffer ring / pad made of high-performance rubber or polyurethane material) installed on the bottom edge protrusion of the elastic connecting part 21 is violently squeezed against the upper wall of the inner ring groove 15 or the structural base, resulting in significant deformation.

[0031] The elastic buffer 22 is compressed forcefully, like a flattened spring, absorbing and dissipating impact energy through its own elastic deformation.

[0032] This is the second level of energy absorption protection. The elastic buffer 22 converts the remaining impact kinetic energy into its own elastic potential energy and ultimately dissipates it in the form of heat. This process greatly mitigates the sharpness of the impact, transforming the huge instantaneous impact force into a relatively gentle and slow force, thus preventing the entire system from generating destructive resonance or high-frequency vibration.

[0033] The compression limit of the elastic buffer 22 also serves as a mechanical limit, preventing the top cover connection 13 from excessively surging upwards and completely detaching from or impacting other critical components. When the impact force weakens or disappears, the elastic potential energy stored in the elastic buffer 22 will be released, pushing the top cover connection 13 downwards to reset, preparing for the next possible impact.

[0034] The impact of the wave is instantaneous. After the brief impact passes, the upward force acting on the top cover connection 13 disappears. At this time, the compressed elastic buffer 22 begins to rebound, releasing elastic potential energy and smoothly pushing the entire top cover connection 13 (including the rotor 14) down along the track of the slide groove 20 until it returns to its original default working position that is tightly fitted with the drive disc 17.

[0035] The entire protection process is completely passive and adaptive, requiring no sensor or electronic control intervention. Once the impact ends, the system automatically and quickly returns to its initial design position, ensuring that rotor 14 is in optimal operating condition. This is crucial for equipment operating in complex hydrological environments, guaranteeing its responsiveness and mission continuity.

[0036] If the elastic buffer 22 is permanently damaged or excessively worn due to an extremely severe impact (far exceeding the design limit), maintenance personnel can easily remove it from the inner ring groove 15 and replace it by squeezing the broken end of the elastic connection 21, which greatly reduces the difficulty and cost of maintenance.

[0037] Through the ingenious mechanical design of "controllable displacement + elastic energy absorption", the rotor protection system forms a highly efficient, reliable and completely passive two-stage buffer protection mechanism. Its operation process perfectly transforms the devastating rigid impact into manageable elastic deformation while ensuring uninterrupted power transmission, greatly improving the survivability and operational reliability of amphibious equipment in harsh wind and wave environments.

[0038] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
