Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, a rainfall simulation device includes a support plate 1, on which a water storage tank 5 is fixedly mounted. The lower part of the water storage tank 5 is connected to a transition water tank 8 via a water supply pipe 6, and a water pump 7 is mounted on the water supply pipe 6. The top of the transition water tank 8 is connected to multiple upward-extending diversion pipes 10. The end of the diversion pipe 10 away from the transition water tank 8 is connected to a flexible water outlet pipe 16. A pressure plate 15 is also raised and lowered above the transition water tank 8. During the raising and lowering process, the pressure plate 15 can press the flexible water outlet pipe 16 to change the outlet direction of the flexible water outlet pipe 16.

[0023] When simulating rainfall using this invention, the supporting plate 1 is first moved to the target position. Then, the water in the storage tank 5 is pumped by the water pump 7 through the water pipe 6 to the transition tank 8. The water then flows through the diversion pipe 10 to form multiple streams, which are finally sprayed out through the flexible outlet pipe 16, creating simulated rainfall around the device. When it is necessary to change the outlet direction of the flexible outlet pipe 16 to adjust the simulated rainfall, the height of the pressure plate 15 can be changed. During its descent, the pressure plate 15 contacts the flexible outlet pipe 16 and pushes its outlet downwards, gradually lowering the outlet direction and thus changing the direction of the water flow to adjust the simulated rainfall. Conversely, moving the pressure plate 15 upwards gradually releases the pressure on the flexible outlet pipe 16. Under the combined action of its own elasticity and the water flow, the outlet of the flexible outlet pipe 16 rotates upwards, gradually raising the outlet direction. By adjusting the water outlet direction of the flexible water outlet pipe 16, the coverage area of ​​simulated rainfall can be changed, and only the lifting pressure plate 15 is needed, which is simple and convenient.

[0024] It should also be noted that a nozzle can be installed at the outlet of the flexible water outlet pipe 16 to change the shape of the sprayed water flow, thereby better simulating rainfall. The nozzle is a conventional technology, and the appropriate type and model can be selected according to actual needs.

[0025] To facilitate the installation of the diversion pipe 10, a diversion plate 9 is fixedly installed on the top of the transition water tank 8. The diversion plate 9 has multiple through holes evenly distributed along the circumference. The diversion pipe 10 passes through the corresponding through holes and is fixedly connected to the diversion plate 9. The diversion plate 9 and the through holes can fully fix the diversion pipe 10, ensuring that the water flow in the transition water tank 8 can be transported to the flexible outlet pipe 16 through the diversion pipe 10.

[0026] Furthermore, the transition water tank 8 is fixedly connected to a top plate 13 via multiple connecting rods 12. The top plate 13 is located above and parallel to the diversion plate 9, with a distance between the top plate 13 and the diversion plate 9 forming an adjustment space 14. The diversion pipe 10 passes upward through the top plate 13 and connects to the flexible water outlet pipe 16. A valve 11 is installed on the portion of the diversion pipe 10 located in the adjustment space 14. When it is only necessary to generate simulated rainfall in a certain area around the device, the on / off state of the diversion pipe 10 can be changed by the valve 11, so that a portion of the flexible water outlet pipe 16 can spray water, while the remaining flexible water outlet pipe 16 is cut off, thereby achieving the effect of controlling the coverage area of ​​simulated rainfall.

[0027] The pressure plate 13 is specifically configured as follows: an adjusting bolt 19 passes through the top plate 13 and also through the pressure plate 15. A spring 20 is installed between the pressure plate 15 and the top plate 13. By rotating the adjusting bolt 19, its height can be changed. During the downward movement of the adjusting bolt 19, its head pushes the pressure plate 15 downward, compressing the spring 20. Conversely, during the upward movement of the adjusting bolt 19, the spring 20 rebounds and drives the pressure plate 15 upward. Throughout this process, the pressure plate 15 remains in contact with the head of the adjusting bolt 19, allowing for subsequent downward movement of the pressure plate 15 using the head of the adjusting bolt 19. With this structure, the pressure plate 15 can be adjusted up and down simply by rotating the adjusting bolt 19, making operation simple and quick.

[0028] To ensure the stability of the position of the spring 20 and to ensure that the spring 20 can stably push the pressure plate 15 upward, the spring 20 is sleeved on the adjusting bolt 19. The adjusting bolt 19 is used to restrict the spring 20, so as to prevent the spring 20 from being deflected and causing the pushing force direction to be deflected when pushing the pressure plate 15, which would result in the pressure plate 15 not being able to move smoothly.

[0029] To create simulated rainfall around the device, the outlet of the flexible water outlet pipe 16 needs to be angled upwards. Furthermore, to ensure the pressure plate 15 can smoothly change the direction of the outlet of the flexible water outlet pipe 16, an inverted conical guide block 18 is fixedly connected to the lower surface of the pressure plate 15. During the lifting and lowering of the pressure plate 15, the conical surface of the guide block 18 presses against the flexible water outlet pipe 16. By utilizing the contact between the peripheral sidewall of the guide block 18 and the flexible water outlet pipe 16, the contact area can be increased, allowing for better adjustment of the direction of the flexible water outlet pipe 16.

[0030] Considering that the flexible outlet pipe 16 may vibrate during water flow, potentially causing instability in the outlet direction and affecting the simulated rainfall, a friction sleeve 17 is fixedly fitted onto the flexible outlet pipe 16 to prevent this. A friction layer that mates with the friction sleeve 17 is provided on the conical surface of the guide block 18. The cooperation between the friction sleeve 17 and the friction layer enhances the stability of the outlet position of the flexible outlet pipe 16, preventing outlet vibration from causing confusion in the simulated rainfall direction. Both the friction sleeve 17 and the friction layer can be made of a rough-surfaced silicon carbide material.

[0031] To facilitate the movement of the entire device, a number of casters 2 are connected to the lower surface of the support plate 1, and a pushing assembly is provided on the upper surface of the support plate 1. The water storage tank 5 is located between the transition water tank 8 and the pushing assembly. The pushing assembly includes at least one pushing rod 3 that is inclined and fixed on the support plate 1 and at least one handle 4 that is correspondingly fixed to the top of the pushing rod 3.

[0032] Finally, it should be noted that, in order to ensure greater clarity in the attached diagrams and to better illustrate the structure of the diversion pipe 10 and the flexible outlet pipe 16, the attached diagrams are slightly modified. Figure 1 and 2 The diagram only shows one diversion pipe 10 and one soft water outlet pipe 16, which does not mean that this utility model only uses one diversion pipe 10 and one soft water outlet pipe 16.

[0033] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0034] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
