Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal rainwater engineering, in particular to a rainwater pipeline end storage device. Background Art
[0002] With the wide application of sponge city technology, related sponge city products have entered the actual application stage. At the same time, the defects and deficiencies of the products are also revealed in practical use. One of the problems is that at present, due to the too low greening area of the plot, the plot cannot store enough runoff rainwater in accordance with relevant specifications and requirements by using the green space. Therefore, a large number of water storage modules are built during the construction process to store rainwater. The construction of water storage modules not only increases the cost of sponge construction of the plot, but also occupies a large area and has cumbersome later maintenance. At present, many water storage modules no longer have the function of rainwater storage and reuse due to improper maintenance. Due to the loss of their use functions, some water storage modules have been filled with silt and garbage, while another part has serious blackening and odor due to the long-term storage of rainwater inside. Even more seriously, some water storage modules have collapsed, seriously affecting the use safety of the plot. Therefore, there is an urgent need for a device that can effectively store rainwater underground, has the ability to discharge rainwater, can be used stably for a long time, and reduces the maintenance cost. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art, aiming to provide a device that can effectively store rainwater underground, has the ability to discharge rainwater, can be used stably for a long time, and reduces the maintenance cost.
[0004] To achieve the above purpose, the utility model is realized by the following technical solutions:
[0005] A rainwater pipeline end storage device includes a main body. The main body is a cylindrical structure with a closed bottom and an open top. The outer wall of the main body is sequentially provided with a drain port, a water inlet, and a sludge discharge port from top to bottom. The top of the main body is flush with the outdoor ground level. The drain port is connected to the municipal rainwater drainage pipeline, the water inlet is connected to the end of the rainwater pipe network, and a gate valve is arranged at the rear end of the sludge discharge port.
[0006] Further, the main body structure is a cylinder or a cuboid.
[0007] Compared with the prior art, the utility model has the following beneficial effects:
[0008] The utility model is easy to maintain. The sludge is discharged by means of gravity flow. Through hydraulic calculation, during the process of rainwater discharge, the dirt suspended in the rainwater will be directly discharged into the municipal rainwater pipeline through the overflowing rainwater. The sludge with larger particles, such as sludge and stones, will be deposited at the bottom of the device, which is convenient for regularly opening the gate valve to discharge the sludge. Compared with the water storage module, it saves material costs, reduces excavation costs, and the small volume of the device also reduces the land use cost of the construction unit. Moreover, there is no need to build a rainwater reuse pipeline, so the corresponding supporting equipment construction cost is also reduced, and the cost of sponge city construction is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 2 is a top view of the utility model.
[0011] Reference numerals:
[0012] 1 - water inlet, 2 - drain outlet, 3 - sludge discharge port, 4 - main body. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0013] The utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.
[0014] As Figure 1 and Figure 2 shown, a rainwater pipeline end storage device includes a main body 4. The main body 4 is a cylindrical structure with a closed bottom and an open top. The outer wall of the main body 4 is sequentially provided with a drain outlet 2, a water inlet 1 and a sludge discharge port 3 from top to bottom. The top of the main body 4 is flush with the outdoor ground level. The drain outlet 2 is communicated with the municipal rainwater drainage pipeline, the water inlet 1 is communicated with the end of the rainwater pipe network, and a gate valve is arranged at the rear end of the sludge discharge port 3.
[0015] Among them, the structure of the main body 4 is a cylinder or a cuboid. The columnar structure can facilitate the main body 4 to play the role of water storage. The drain outlet 2, the water inlet 1 and the sludge discharge port 3 arranged from top to bottom can be in the form of reserved holes or reserved connecting pipes, which is convenient for docking with the corresponding rainwater pipes in the later stage.
[0016] The main body 4 of this device is installed at the end of the plot rainwater pipe network. The inlet 1 is connected to the end of the plot rainwater pipe network, and the drain outlet 2 is connected to the municipal rainwater drainage pipeline outside the plot. The top of the main body 4 is flush with the outdoor ground level, and the upper part is closed by an inspection well cover or other covering methods for easy maintenance. Since the elevation of the drain outlet 2 is higher than that of the inlet 1, during rainfall, the rainwater in the rainwater pipe network that does not exceed the elevation of the drain outlet 2 will be stored in the entire rainwater pipeline, while the rainwater that exceeds the elevation of the drain outlet 2 will overflow into the municipal rainwater pipeline and be discharged, so as to realize the rainwater storage function of the rainwater pipe network.
[0017] Due to the elevation difference between the inlet 1 and the bottom surface of the main body 4, during the initial rainfall, the rainwater will wash the sundries originally deposited in the pipeline into the space below the inlet 1. Suppose the rear end of the sludge discharge port 3 is connected to a gate valve, and the rear end of the gate valve is connected to the municipal rainwater pipe network or a sludge well. When the rainwater pipeline needs to be dredged, the gate valve is opened, and the silt can be smoothly discharged into the municipal rainwater inspection well or the sludge well. If it is discharged into the sludge well, the sludge can be discharged to the corresponding discharge pipeline through the sludge lifting equipment.
[0018] After the rainfall stops, a mobile lift pump can be used to recycle the rainwater. Since the rainwater pipe network stores rainwater and the rainwater pipe network is evenly distributed within the plot, if rainwater needs to be recycled at any point, directly open the rainwater well cover at the corresponding point and place the mobile lift pump into it, then the recycling of rainwater can be achieved without constructing a separate rainwater recycling pipe network. That is, when recycling, open any inspection well of the rainwater pipeline, place the lift pump at the bottom of the rainwater inspection well, and the rainwater stored in the rainwater pipeline can be lifted for use.
[0019] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
