Description

Technical Field

[0001] This utility model belongs to the field of water supply and drainage technology, specifically relating to a stepped drop well with high energy dissipation efficiency. Background Technology

[0002] In drainage pipes, when the drop in elevation is significant and the normal pipe slope cannot meet design requirements, a manhole with an internal drop is constructed to satisfy the design. Because the water flow drops within the manhole, such a manhole is called a drop manhole. Compared to ordinary manholes, drop manholes need to eliminate the energy of the falling water to reduce the impact damage to the pipes and the manhole itself caused by the large drop.

[0003] For example, a stepped drop well provided by Chinese Patent Publication No. CN217759224U includes an inlet pipe, an outlet pipe, a water flow step, and a filter device. The water flow step has no less than two steps, and the two ends of the water flow step are respectively connected to the inlet pipe and the outlet pipe. The height of the inlet pipe is higher than that of the outlet pipe. This device uses the water flow step to buffer the impact force of the falling water in stages, thereby reducing the noise generated when the water flows down.

[0004] As described in the prior art of the aforementioned patent, although the energy dissipation of water flowing from a high place to a low place can be achieved through water steps, the energy dissipation effect is not obvious enough, and the overall structure of the device is relatively strong, making it difficult to repair damage caused by water flow after a long period of time. Utility Model Content

[0005] The purpose of this invention is to provide a stepped drop well with high energy dissipation efficiency, which can dissipate energy by the water flow impacting the stones in the sink basket. In each stage of the water tank, the water flow impacts the stones multiple times, which can perform multiple energy dissipation actions, thereby improving the energy dissipation effect of the water flow falling from a height.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] A stepped drop well with high energy dissipation efficiency includes a main body of the well. A water inlet pipe is installed at the upper end of one side of the main body of the well, and a drain pipe is installed at the lower end of the other side of the main body of the well. Water tanks are arranged in a stepped manner inside the main body of the well. A water basket is set in each water tank. Stones for energy dissipation of water are laid in the water basket. Drainage holes are opened at the bottom of each water tank and the bottom of the water basket. A water-flow ramp is set below each water tank to guide the water flow to the next water tank.

[0008] In a preferred embodiment, the number of water tanks arranged in a stepped manner is at least two sets.

[0009] In a preferred embodiment, an inspection port is provided at the upper end of the caisson body, and an end cap is engaged and connected inside the inspection port.

[0010] In a preferred embodiment, the inner wall of the caisson body is provided with a slot, and the slot extends upward to the top of the caisson body. A baffle plate is provided inside the caisson body near the water inlet pipe, and the baffle plate is engaged in the slot by a locking block.

[0011] In a preferred embodiment, the submerged basket and the water tank are detachable.

[0012] In a preferred embodiment, each submerged basket is provided with lifting rings at both ends.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model allows water flowing from a height to cascade through a series of stages in a water tank. As the water flows through each stage, it repeatedly impacts the stones in the sinking basket, dissipating the energy of the water flow and reducing the impact force when the water falls from a height. Furthermore, since the sinking basket is detachable from the water tank, it can be lifted out of the tank after prolonged use, and the stones inside can be replaced. This facilitates cleaning and maintenance of the cascade, extending its service life. Attached Figure Description

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0024] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0025] Please see the appendix Figure 1 and Figure 2 As shown, this utility model provides a stepped drop well with high energy dissipation efficiency, including a well body 1, an inlet pipe 2 installed at the upper end of one side of the well body 1, a drain pipe 3 installed at the lower end of the other side of the well body 1, water troughs 4 arranged in a stepped manner inside the well body 1, a sinking basket 5 set in each water trough 4, and stones for energy dissipation of water laid in the sinking basket 5, and a drain hole 7 opened at the bottom of each water trough 4 and the bottom of the sinking basket 5, and a water-following slope 6 set below each water trough 4 to guide the water flow to the next water trough 4;

[0026] In this embodiment, when the drop well is in operation, water flows into the main body 1 of the caisson through the inlet pipe 2. Within the main body 1, the water flows sequentially from high to low through each stepped water trough 4. As the water flows through each water trough 4, it impacts the stones in the sink basket 5, thereby dissipating energy. Furthermore, as the water flows downwards from the upper right in each water trough 4, it exits from the drain hole 7 at the bottom of the water trough 4 to the corresponding downstream slope 6, and then flows down the downstream slope 6 into the next water trough 4. This process allows for the gradual dissipation of energy from the water flow. The device uses a stepped energy dissipation system, where water flowing from a height flows through a stepped water tank 4 in stages. During each stage of the water tank 4, the water flow is repeatedly impacted by stones in the sinking basket 5, thus reducing the impact force generated when the water falls from a height. Furthermore, since the sinking basket 5 is detachable from the water tank 4, it can be lifted out of the water tank 4 after prolonged use, and the stones in the sinking basket 5 can be replaced. This facilitates cleaning and maintenance of the water drop well, extending its service life.

[0027] It is worth noting that the size of the stones in the sinking basket 5 should be appropriate, neither too large nor too small. The size should be about the same as that of a basketball. They should be laid in multiple layers in the sinking basket 5, with gaps between each stone to facilitate the downward flow of water. The diameter of the drain hole 7 at the bottom of the sinking basket 5 and the water tank 4 should be much smaller than the diameter of the stones.

[0028] In this embodiment, there are at least two sets of water tanks 4 arranged in a stepped manner. Setting multiple sets of water tanks 4 and submerged baskets 5 can improve the energy dissipation effect of water flow.

[0029] Please see Figure 2 and Figure 3 As shown, an inspection port 11 is provided at the upper end of the caisson body 1. An end cover 13 is fitted inside the inspection port 11. When maintenance is required inside the caisson body 1, the end cover 13 can be lifted and the water basket 5 inside can be hoisted or cleaned through the inspection port 11. When maintenance is not required, the inspection port 11 can be covered by the end cover 13.

[0030] In this embodiment, please refer to Figures 1 to 2 Figure 3 As shown, a slot 12 is provided on the inner wall of the caisson body 1, and the slot 12 extends upward to the top of the caisson body 1. A baffle 8 is provided inside the caisson body 1 near the water inlet pipe 2. The baffle 8 is engaged and connected in the slot 12 by a locking block 81.

[0031] To prevent the water flowing out of the inlet pipe 2 from being too fast and spraying too far, causing the water to directly pass over the water tank 4 and the sink basket 5 and fail to achieve the energy dissipation effect, a baffle plate 8 is installed at the outlet of the inlet pipe 2. The baffle plate 8 blocks the water flow to prevent it from spraying too far, so that the water in the inlet pipe 2 flows through the highest level water tank 4 step by step to dissipate energy. In addition, the baffle plate 8 is connected to the slot 12 on the inner wall of the caisson body 1 by the locking block 81, so that the baffle plate 8 can be disassembled, replaced and repaired.

[0032] Please see Figure 3 and Figure 4 As shown, the submerged basket 5 and the water tank 4 are detachable, and each submerged basket 5 is provided with a lifting ring 51 at both ends;

[0033] In this embodiment, since the sinking basket 5 and the water tank 4 are detachable, the sinking basket 5 can be lifted out of the water tank 4 after the drop well has been used for a long time, and the stones in the sinking basket 5 can be replaced, which facilitates the cleaning and maintenance of the drop well and improves its service life. When hoisting the sinking basket 5, the rope can be tied to the lifting ring 51 and connected to the sinking basket 5 for easy lifting.

[0034] The working principle of this utility model is as follows: When the drop well is in operation, the water flows into the main body 1 of the caisson through the inlet pipe 2. Inside the main body 1, the water flows from high to low through each stepped water trough 4. When the water flows in each water trough 4, it impacts the stones in the sink basket 5, thereby dissipating the energy of the water flow. When the water flows downward from the upper right in each water trough 4, it flows out from the drain hole 7 at the bottom of the water trough 4 to the corresponding downhill slope 6 at the bottom of the water trough 4, and then flows along the downhill slope 6 to the next water trough 4. This process can dissipate the energy of the water flow step by step.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
