DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.
[0021] The specific implementation process is as follows: Embodiment 1: See also Figure 1-7The present invention provides a technical solution: a suspended liner shock-absorbing water tank, the suspended liner shock-absorbing water tank comprises a box body 1, a buffer pad 2 is fixedly installed on the inner wall of the box body 1, a support device 3 is arranged inside the buffer pad 2, a limiting ring 4 is fixed on the upper side of the support device 3, a plurality of clamping devices 5 are symmetrically distributed on the side of the support device 3, an inner liner 6 is movably embedded in the support device 3, a placement groove 201 is opened on the inner wall of the buffer pad 2, a plurality of buffer grooves 202 are evenly distributed on the side of the placement groove 201, the function of the buffer groove 202 is to effectively buffer the external impact force when the water tank is vibrated, reduce the influence on the support device 3 and the inner liner 6, and play a preliminary shock-absorbing effect, the support device 3 comprises a support damping rod 301 fixedly installed in the middle of the placement groove 201, and the support damping rod 301 is fixedly installed in the middle of the placement groove 201. A support plate 302 is fixedly connected to the upper side of the damping rod 301, and a plurality of support slide plates 303 are evenly arranged on the side of the support plate 302. The inner wall of the support plate 302 is designed with an arc 304. When the weight of the inner liner 6 changes, the support damping rod 301 can make corresponding displacement adjustments according to the pressure change. The support plate 302 is used to carry the inner liner 6. The support slide plate 303 can slide in the buffer groove 202, and cooperate with the buffer groove 202 to further enhance the shock absorption performance. The arc 304 is consistent with the bottom shape of the inner liner 6, providing stable support for the inner liner 6. A plurality of limit grooves 401 are evenly arranged on the side of the limit ring 4. The limit grooves 401 are mainly used to install the clamping device 5, provide accurate positioning and necessary limit for the clamping device 5, and ensure its stability during operation. In order to ensure the safety and accuracy of the product, the clamping device 5 is composed of a clamping shaft 501 fixedly installed on the inner wall of the limiting groove 401, and a clamping arm 502 movably embedded in the surface of the clamping shaft 501. One end of the clamping arm 502 is movably connected with a first adjusting shaft 503. An adjusting rod 504 is fixedly provided on the surface of the first adjusting shaft 503. A clamping damping rod 505 is installed in the middle of the adjusting rod 504. A second adjusting shaft 506 is fixedly connected below the adjusting rod 504. The second adjusting shaft 506 is movably embedded in the upper part of the supporting slide plate 303. When the weight of the inner liner 6 increases and the supporting device 3 is displaced downward, the adjusting rod 504 is driven to rotate by the second adjusting shaft 506, and then the clamping arm 502 rotates around the clamping shaft 501 to achieve clamping of the inner liner 6. The clamping damping rod 505 is adjusted during the adjustment process. The swivel plate 507 is fixedly connected to the other end of the clamping arm 502, and a rotating shaft 508 is movably installed in the middle of the rotating plate 507. A friction plate 509 is fixedly provided on the surface of the rotating shaft 508, and a clamping ring 510 is fixedly connected to one side of the friction plate 509. As the clamping arm 502 rotates, the rotating plate 507 rotates around the rotating shaft 508, driving the clamping ring 510 to tightly clamp the inner liner 6. The existence of the friction plate 509 increases the friction force during the rotation process, so that the clamping ring 510 can provide corresponding and stable clamping force according to the weight change of the inner liner 6, ensuring that the inner liner 6 can be firmly fixed under different weight conditions. A plurality of clamping rings 101 are symmetrically arranged on the outer wall of the box body 1.The design of the clamp ring 101 facilitates the installation and fixation of the water tank. The user can pass a rope or other connecting parts through the clamp ring 101 to firmly install the water tank in the desired position, thereby improving the convenience and stability of the water tank installation. The buffer groove 202 is movably adapted to the supporting slide plate 303. This adaptation relationship enables the supporting slide plate 303 to slide flexibly in the buffer groove 202. When the water tank is vibrated or the weight of the inner tank 6 changes, the two cooperate with each other to effectively absorb and disperse energy, further improving the shock absorption performance of the water tank and ensuring the movement trajectory of the supporting device 3. The clamping ring 510 is adapted to contact with the outer wall of the inner tank 6, and the clamping ring 510 can fit tightly against the outer wall of the inner tank 6. According to the weight change of the inner tank 6, a proper clamping force is provided to ensure that the inner tank 6 remains stable in the water tank and will not be damaged due to shaking. A lifting shaft 511 is fixed on the rotating plate 507 and the friction plate 509. A lifting spring 512 is fixed on the surface of the lifting shaft 511. The lifting spring 512 assists the movement of the rotating plate 507 and the friction plate 509 to a certain extent. When the clamping device 5 needs to be adjusted, the elastic force provided by the lifting spring 512 can make the operation easier and more convenient. At the same time, it also helps to maintain the stability of the clamping device 5 under different working conditions, ensuring that the rotating plate 507 and the friction plate 509 will not naturally sag due to gravity and affect the placement of the inner tank 6; The specific implementation process is as follows: The box body 1 serves as the outer shell of the entire water tank, protecting the internal structure and accommodating the inner tank 6. The symmetrically arranged snap rings 101 on the outer wall provide convenience for the installation and fixation of the water tank. In practical applications, the snap rings 101 can be passed through ropes or other connecting parts to firmly install the water tank on the corresponding bracket, wall or transportation equipment, ensuring that the water tank can maintain a stable position in different environments. The placement groove 201 on the inner wall of the buffer pad 2 is used to place the support device 3 to provide a stable foundation for it. When the water tank is subjected to external vibration, the buffer groove 202 can play a key buffering role. The external vibration energy will first be transmitted to the buffer pad 2, and the buffer groove 202 absorbs and disperses the energy through its own elastic deformation, reducing the vibration to the support device 3 and the inner tank. 6, thereby achieving a preliminary shock-absorbing effect. The support damping rod 301, as the core component of the support device 3, will undergo corresponding displacement when subjected to the pressure generated by the weight change of the inner tank 6. When the weight of the water-filled inner tank 6 increases and the pressure increases, the support damping rod 301 will be compressed downward, driving the support plate 302 and the support slide plate 303 to descend together. The support plate 302 provides a direct support surface for the inner tank 6, and the curvature 304 of its inner wall is adapted to the bottom shape of the inner tank 6, which can better disperse the weight of the inner tank 6 and ensure the stability of the placement of the inner tank 6. The sliding of the support slide plate 303 in the buffer groove 202 can, on the one hand, adjust the support position as the weight of the inner tank 6 changes, and on the other hand, cooperate with the buffer groove 202 when the water tank is vibrated, further Absorb and disperse vibration energy and enhance shock absorption effect. The limiting groove 401 on the limiting ring 4 accurately defines the installation position and range of motion of the clamping device 5. In the entire system, the limiting ring 4 plays a role of positioning and restraint, ensuring that the clamping device 5 can accurately clamp the inner liner 6 during operation and maintain a stable working state under various conditions without deviation or shaking, thereby ensuring the reliability of the fixation of the inner liner 6. When the weight of the inner liner 6 increases and causes the support device 3 to move downward, the second adjustment shaft 506 will move with the descent of the supporting slide plate 303, thereby driving the adjustment rod 504 to rotate. The adjustment rod 504 causes the clamping arm 502 to rotate around the clamping shaft 501 through the first adjustment shaft 503, and begins to clamp the inner liner 6. During this process, the clamping damping rod 505 plays a role of buffering and stabilizing adjustment, avoiding the clamping process from being too stiff and ensuring that the clamping force is uniform and stable. As the weight of the inner tank 6 increases further, the rotating plate 507 rotates around the rotating shaft 508, driving the clamping ring 510 to gradually tighten, and providing corresponding clamping force according to the weight change of the inner tank 6. The friction plate 509 increases the friction force during the rotation process, making the clamping of the clamping ring 510 more stable and reliable, ensuring that the inner tank 6 can be firmly fixed in the water tank under different weight conditions. In addition, the lifting shaft 511 and the lifting spring 512 provide assistance for the movement of the rotating plate 507 and the friction plate 509. When it is necessary to adjust the clamping device 5, the elastic force of the lifting spring 512 can make the operation easier and more convenient.At the same time, it also helps to maintain the stability of the clamping device 5 in different working states. The inner tank 6 is the core component of the water tank for storing water. During the water filling process, as the amount of water increases, the weight of the inner tank 6 gradually increases, which produces greater pressure on the supporting device 3, thereby triggering a series of adjustment actions of the supporting device 3 and the clamping device 5 to ensure that the inner tank 6 is always in a stable state. When the water tank is vibrated, the above-mentioned shock-absorbing structure will work together to protect the inner tank 6 from excessive vibration and ensure its sealing and service life.

When the impact height reaches a certain height, the water source will fall under the influence of gravity. At this time, part of the water splashes will pass through the conical plate 704, and then the water will flow out through the notch 705 of the conical plate 704 and impact the transmission water wheel 707 to rotate. The transmission water wheel 707 drives the first bevel gear 708 to rotate, and then drives the transmission rod 710 to rotate through the second bevel gear 709, driving the generator 711 to generate electricity, and the generated electricity is stored in the storage tank.
