Abstract
Description
Technical Field
[0001] This utility model relates to the field of landscape water decoration technology, specifically a non-splashing rainwater chain drainer. Background Technology
[0002] Rain chains, also known as rain chains, originated in Japanese architecture and are part of the rainwater drainage system. They are mainly used to divert rainwater, protecting buildings from rainwater erosion and thus helping to protect the buildings. Rain chains also have a noble and elegant architectural decorative function, and are suitable for the decoration of the corridors of villas, courtyards, parks and other buildings. Traditionally, rain chains are decorative water guiding devices in building drainage systems, guiding rainwater from the roof to flow down naturally through the chain structure, combining functionality and aesthetics.
[0003] Traditional rain chains still have certain shortcomings in use: water is easily splashed outwards by wind or gravity when flowing through the chain links, resulting in slippery ground and damp surrounding walls. In addition, the rainwater is scattered and difficult to collect and reuse. Especially in heavy rain, the impact of the water flow exacerbates the splashing phenomenon, which may erode the foundation or damage green facilities. Existing improvement solutions mostly control the water flow by adding diversion channels or slow-descent structures, but gaps still exist at the joints between the chain links, making it difficult to completely suppress splashing. Moreover, the complex design weakens the decorative effect of the rain chain. Utility Model Content
[0004] The purpose of this utility model is to provide a non-splashing rainwater chain drain to solve the problems mentioned in the background art, where water is easily splashed outwards by wind or gravity when flowing through the chain links, resulting in slippery ground, damp surrounding walls, and scattered rainwater droplets that are difficult to collect and reuse. Especially in heavy rain, the impact force of the water flow exacerbates the splashing phenomenon, which may erode the foundation or damage green facilities. Existing improvement solutions mostly control the water flow by adding diversion channels or slow-descent structures, but gaps still exist at the joints between the chain links, making it difficult to completely suppress splashing. Moreover, the complex design weakens the decorative effect of the rainwater chain.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A non-splashing rainwater chain drainer includes a water guide cup, a support member at the top of the water guide cup, a threaded rod at the top of the support member, the threaded rod passing through the support member and extending into the water guide cup, the threaded rod being rotatably connected to the support member, a swivel nut and a fixing nut being threadedly connected to the top of the threaded rod respectively, the swivel nut being located at the top of the support member, the fixing nut being located at the bottom of the support member, a spherical structure being fixedly connected to the bottom of the spherical structure, the connecting nut being located at the bottom of the fixing nut, and the water guide cup consisting of an upper cylindrical structure.
[0007] As a preferred embodiment of the present utility model, an outer lining main body is provided at the bottom of the water guiding cup. An outer lining plate is fixedly connected to the side surface of the outer lining main body. An outer lining eaves surface is fixedly connected to the top of the outer lining plate. The water guiding cup extends into the outer lining main body and is snap-connected to the outer lining main body.
[0008] As a preferred embodiment of the present utility model, a water guiding buffer slope is fixedly connected to the bottom of the water guiding cup. A lower cylindrical structure is fixedly connected to the bottom of the water guiding buffer slope. The lower cylindrical structure, the water guiding buffer slope and the water guiding cup are interconnected.
[0009] As a preferred embodiment of the present utility model, a reinforcing plate is provided on the outer surface of the outer lining main body. The reinforcing plate is fixedly connected to the outer lining plate. The outer lining main body is in a conical structure, and the diameter of the upper water inlet end is larger than the diameter of the lower water outlet end.
[0010] As a preferred embodiment of the present utility model, the end of the threaded rod extends to the bottom of the lower cylindrical structure. The spherical structure is located at the bottom of the lower cylindrical structure.
[0011] As a preferred embodiment of the present utility model, the caliber of the upper cylindrical structure is larger than that of the lower cylindrical structure. The shapes of both the upper cylindrical structure and the lower cylindrical structure are conical.
[0012] As a preferred embodiment of the present utility model, the reinforcing plate is located at the bottom of the outer lining plate. The material of the reinforcing plate is brass.
[0013] As a preferred embodiment of the present utility model, the shape of the support member is U-shaped. The inner surfaces of the lower cylindrical structure, the water guiding buffer slope and the water guiding cup are coated with an anti-corrosion solution.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] 1. In the present utility model, by setting the combined use of the threaded rod, the羊角 nut (it should be noted that the Chinese term '羊角螺母' might be a specific name in the original text, and if there is a more accurate English equivalent, it can be replaced), the fixing nut, the spherical structure and the connecting nut, it is convenient to adjust the distance between the water outlet device and the rain chain, so as to reduce the outward splashing of water flow affected by wind due to the excessive distance between the two. The connecting nut is used to connect the rain chain structure, and its internal structure is a thread. The spherical structure is used to fix the connecting nut on the threaded rod. By adjusting the羊角 nut, the length of the entire rain chain can be realized, thereby achieving the overall fixation of the rain chain. By adjusting the羊角 nut, the distance between the water outlet device and the rain chain can be realized, reducing the water splashing situation.
[0016] 2. In this utility model, by using a combination of a water guide cup, a water guide buffer slope, a lower cylindrical structure, an upper cylindrical structure, a support member, and a reinforcing plate, splashing during the use of the rain chain drain can be effectively prevented. The design of the water guide cup can collect and guide the water flow. The bottom diameter of the upper cylindrical structure is directly larger than the bottom diameter of the lower cylindrical structure. This structure, which is larger at the top and smaller at the bottom, is more conducive to the concentrated downward flow of water. The water guide buffer slope can slow down the water flow speed. The support member is used to fix and strengthen the structure of the entire drain, ensuring that the drain will not shake or fall off during use. The reinforcing plate further enhances the load-bearing capacity of the drain, enabling it to withstand greater water flow impact. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] For examples, please refer to Figures 1-3 This utility model provides a technical solution:
[0023] A non-splashing rainwater chain drainer includes a water guide cup 3, a support member 7 on the top of the water guide cup 3, a threaded rod 4 on the top of the support member 7, the threaded rod 4 passing through the support member 7 and extending into the water guide cup 3, the threaded rod 4 being rotatably connected to the support member 7, a horn nut 5 and a fixing nut 6 being threadedly connected to the top of the threaded rod 4 respectively, the horn nut 5 being located at the top of the support member 7, the fixing nut 6 being located at the bottom of the support member 7, a spherical structure 9 being fixedly connected to the bottom of the spherical structure 9, a connecting nut 8 being fixedly connected to the bottom of the fixing nut 6, the water guide cup 3 being composed of an upper cylindrical structure 14, an outer liner body 13 being provided at the bottom of the water guide cup 3, an outer liner plate 2 being fixedly connected to the side of the outer liner body 13, an outer liner eaves surface 12 being fixedly connected to the top of the outer liner plate 2, and the water guide cup 3 extending into the outer liner body 13 and engaging with the outer liner body 13.
[0024] The rainwater is guided by the water-guiding buffer slope 10 and flows slowly down to the lower cylindrical structure 11, effectively reducing the impact of the water flow and preventing water from splashing out.
[0025] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, a water-guiding buffer slope 10 is fixedly connected to the bottom of the water-guiding cup 3. A lower cylindrical structure 11 is fixedly connected to the bottom of the water-guiding buffer slope 10. The lower cylindrical structure 11, the water-guiding buffer slope 10, and the water-guiding cup 3 are connected. A reinforcing plate 1 is provided on the outer surface of the outer liner body 13. The reinforcing plate 1 is fixedly connected to the outer liner plate 2. The outer liner body 13 has a conical structure. The diameter of the upper water inlet end is larger than the diameter of the lower water outlet end. The end of the threaded rod 4 extends to... At the bottom of the lower cylindrical structure 11, the spherical structure 9 is located at the bottom of the lower cylindrical structure 11. The diameter of the upper cylindrical structure 14 is larger than that of the lower cylindrical structure 11. Both the upper cylindrical structure 14 and the lower cylindrical structure 11 are conical in shape. The reinforcing plate 1 is located at the bottom of the outer liner plate 2. The reinforcing plate 1 is made of brass. The support 7 is shaped like a "Z". The inner walls of the lower cylindrical structure 11, the water-guiding buffer slope 10, and the water-guiding cup 3 are coated with an anti-corrosion solution.
[0026] The design of the water guide cup 3 can collect and guide the water flow. The bottom of the upper cylindrical structure 14 is directly larger than the bottom diameter of the lower cylindrical structure 11. This structure, which is larger at the top and smaller at the bottom, is more conducive to the concentrated downward flow of water. The water guide buffer slope 10 can slow down the water flow speed.
[0027] The working process of this utility model is as follows: When using the non-splashing rainwater chain drainer designed in this solution, first check whether the drainer is working properly, then install the device in a suitable working area. Rainwater then flows through the rainwater chain into the water guide cup 3. Inside the water guide cup 3, the rainwater is guided by the water-guiding buffer slope 10 and flows slowly down to the lower cylindrical structure 11, effectively reducing the impact force of the water flow and preventing splashing. Simultaneously, the design of the outer lining eaves 12 further ensures that water will not splash outside the device, keeping the surrounding environment dry. As the rainwater continues to flow in and pass through the upper cylindrical structure 14, it is finally discharged smoothly into the predetermined drainage area. Throughout the entire process, components such as reinforcing plate 1, outer liner plate 2, threaded rod 4, ram's nut 5, fixing nut 6, support 7, connecting nut 8, and spherical structure 9 work together to ensure the stability and durability of the drain. The design of the water guide cup 3 can collect and guide the water flow. The bottom diameter of the upper cylindrical structure 14 is directly larger than the bottom diameter of the lower cylindrical structure 11. This structure, which is larger at the top and smaller at the bottom, is more conducive to the concentrated downward flow of water. The water guide buffer slope 10 can slow down the water flow speed, so that the non-splashing rainwater chain drain of this utility model can effectively complete its design function.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
