Description

Technical Field

[0001] This utility model relates to the field of water supply technology, and in particular to a water supply system based on river water intake. Background Technology

[0002] In river-based water supply systems, the water typically contains impurities such as silt and suspended solids. These impurities, after settling in sedimentation tanks, easily lead to siltation at the bottom, affecting sedimentation efficiency and water quality. Traditional cleaning methods rely heavily on manual dredging or external powered machinery, resulting in low efficiency, high maintenance costs, and high energy consumption. While some existing technologies employ mechanical cleaning equipment, these often require additional power sources, such as motors or hydraulic systems, increasing system complexity and operating costs. Furthermore, incomplete cleaning in some systems can easily cause blockages in the sedimentation tanks, affecting the continuity of water supply. Utility Model Content

[0008] To address the issue of impurities being dispersed at the bottom of the sedimentation tank, which hinders transportation, the sedimentation tank is further equipped with a guide surface that slopes downwards from the outer periphery towards the center.

[0009] To address the problem of dispersed impurities at the bottom of the sedimentation tank hindering transport, a further improvement is made by providing a collection chamber at the bottom of the sedimentation tank to accommodate the bottom of the transport compartment and collect impurities.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention. Example 1:

[0015] like Figure 1 This is a schematic diagram of the structure of this utility model, a water supply system based on river water intake, including a water intake pipe 1, a sedimentation tank 2, a water pump 3, a sand separator 4, and a storage tank 5. The input end of the water intake pipe 1 is located in the river channel, the output end of the water intake pipe 1 is connected to the input end of the sedimentation tank 2, the output end of the sedimentation tank 2 is connected to the input end of the water pump 3, the output end of the water pump 3 is connected to the input end of the sand separator 4, and the output end of the sand separator 4 is connected to the input end of the storage tank 5. like Figure 2 , 3 As shown, a cleaning mechanism 6 is arranged inside the settling tank 2. The cleaning mechanism 6 is used to remove impurities settled at the bottom of the settling tank 2. The cleaning mechanism 6 includes a water wheel 61, a transmission assembly 62, a conveying chamber 63, and a screw conveyor 64. The water wheel 61 is rotatably connected to the settling tank 2 and is located at the input port of the settling tank 2. The water wheel 61 is driven by the water flow entering from the input port of the settling tank 2. The water wheel 61 is connected to the transmission assembly 62 and the screw conveyor 64 through transmission. The conveying chamber 63 is fixedly connected to the settling tank 2, and the bottom end of the conveying chamber 63 extends into the settling tank. 2. The bottom of the conveying chamber 63 extends into the sedimentation tank 2. The bottom of the conveying chamber 63 is provided with an inlet 631 and the top of the conveying chamber 63 is provided with an outlet 632. The spiral conveying rod 64 is rotatably connected to the conveying chamber 63 and is located inside the conveying chamber 63. The cleaning mechanism 6 operates synchronously with the water flow to achieve continuous or semi-continuous removal of impurities, effectively preventing sedimentation in the sedimentation tank and ensuring water supply stability. The water flow drives the water wheel 61, which can automatically clean the impurities at the bottom of the sedimentation tank 2 without external energy, reducing energy consumption and maintenance costs.

[0016] The cleaning mechanism 6 includes a fixed box 65, which is connected to the sedimentation tank 2 via a transmission mechanism. The fixed box 65 is used to cover the transmission component 62. Covering the transmission component 62 with the fixed box 65 prevents external impurities from entering, reduces wear, and ensures stable and reliable transmission.

[0017] like Figure 2 , 3 As shown, the transmission assembly 62 includes a first connecting shaft 621, a first bevel gear 622, a second bevel gear 623, a second connecting shaft 624, a first transmission gear 625, a second transmission gear 626, and a third transmission gear 627. The first connecting shaft 621 is rotatably connected to the sedimentation tank 2. The water wheel 61 is mounted on the first connecting shaft 621. The first bevel gear 622 is arranged on the first connecting shaft 621. The axes of the first connecting shaft 621 and the second connecting shaft 624 are perpendicular to each other. The second bevel gear 623 and the first transmission gear 625 are both mounted on the second connecting shaft 624. The first bevel gear 622 and the second bevel gear 623 mesh. The third transmission gear 627 is mounted on the screw conveyor rod 64. The second transmission gear 626 is rotatably connected to the fixed box 65.

Through the combination of bevel gears and transmission gears, vertical power transmission is achieved. The structure is robust and the transmission efficiency is high.

[0018] The sedimentation tank 2 has a guide surface 21 that slopes downward from the outer periphery to the center. The guide surface 21 is designed to allow impurities to flow towards the center, making it easier for the cleaning mechanism 6 to handle them centrally and improving cleaning efficiency.

[0019] The bottom of the settling tank 2 is provided with a collection chamber 22 for accommodating the bottom of the conveying chamber 63 and collecting impurities. The collection chamber 22 accommodates the bottom of the conveying chamber and collects impurities, thereby enhancing the impurity capture capability and improving the thoroughness of cleaning.

[0020] Work process: River water flows into sedimentation tank 2 through water intake pipe 1. The water flow velocity decreases, and impurities such as silt settle to the bottom of the tank under gravity. The water flow entering sedimentation tank 2 impacts water wheel 61, causing it to rotate. The power of the water wheel is transmitted through transmission component 62 (such as gears or synchronous belts). Transmission component 62 drives screw conveyor 64 to rotate. Screw conveyor 64 sucks in impurities from the bottom of sedimentation tank 2 through inlet 631 of conveying bin 63 and conveys them upward along conveying bin 63, finally discharging them from outlet 632 of sedimentation tank 2. The settled water is pumped by water pump 3 to sand separator 4 for fine sand removal, and then enters storage tank 5 for storage and use by users. The entire process is automated and operates continuously. Example 2:

[0021] The technical feature that distinguishes Example 2 from Example 1 is: the transmission component. The transmission assembly 62 includes a first connecting shaft 621, a first bevel gear 622, a second bevel gear 623, a second connecting shaft 624, and a synchronous belt. The first connecting shaft 621 is rotatably connected to the sedimentation tank 2. The water wheel 61 is mounted on the first connecting shaft 621. The first bevel gear 622 is arranged on the first connecting shaft 621. The axes of the first connecting shaft 621 and the second connecting shaft 624 are perpendicular to each other. The second bevel gear 623 is mounted on the second connecting shaft 624. The first bevel gear 622 and the second bevel gear 623 mesh. The synchronous belt passes through the second connecting shaft 624 and the screw conveyor 64 and is connected end to end. The use of synchronous belt transmission reduces the use of gears, lowers noise and manufacturing costs, and is flexible in installation and easy to maintain.

[0022] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
