Description
Technical Field
[0001] This utility model relates to the field of water intake equipment technology, and in particular to a cascade sedimentation water intake device. Background Technology
[0002] A water intake device is a device or system used to extract water resources from natural or artificial water sources. It typically consists of a water intake, pipes, a pump, and control components. Driven by mechanical or electrical means, it transports water from the source to the target location. Depending on the application scenario, water intake devices can be divided into domestic, agricultural, and industrial types. Its core function is to ensure a stable and efficient supply of clean water to meet the needs of domestic and industrial water use. Some devices are also equipped with media filtration, ultrafiltration modules, or RO reverse osmosis modules to improve water quality.
[0003] In many fields such as daily life, industrial production, and agricultural irrigation, the requirements for water quality are increasing. Efficient and reliable water intake devices have become the key to ensuring water quality. However, existing water intake devices cannot effectively intercept organic impurities, bacteria, dissolved salt ions, and harmful heavy metal ions, resulting in unsatisfactory raw water quality, increasing the difficulty of downstream water treatment. Furthermore, as the usage time increases, a large number of impurities enter downstream equipment and pipe networks, gradually depositing on the pipe walls, severely reducing water flow velocity, and even causing complete blockage and damage to the system. At the same time, bacterial growth can cause serious deterioration of water quality. Utility Model Content

[0026] 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.
[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention 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 the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0028] 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 the present invention. The phrase "in one 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 excludes other embodiments.
[0029] Example 1:
[0030] Reference Figures 1-6 This is the first embodiment of the present utility model. This embodiment provides a stepped sedimentation and water intake device, including a support 1. A spiral water guide channel 2 is installed on the top of the support 1. A water guide cavity 3 is provided on the inner wall of the spiral water guide channel 2. The water guide cavity 3 has a gradually descending structure design. Multiple sets of flow buffer plates 4 are fixed on the inner wall of the water guide cavity 3. The height of the flow buffer plates 4 is lower than the height of the spiral water guide channel 2.
[0031] The support frame 1 serves as the supporting structure for the entire device, providing an installation foundation for other components, ensuring the stability and integrity of the device, and enabling the various components to be arranged and operated in an orderly and stable manner. The spiral water guide channel 2 is the main channel through which water flows and undergoes preliminary treatment. Its spiral shape extends the water flow path and increases the residence time of the water in the device, which is beneficial for subsequent filtration and sedimentation processes. Through the water guide cavity 3 set in its inner wall and its gradually descending structural design, the water can flow gradually downward along the water guide cavity 3 in the spiral water guide channel 2, forming an orderly water flow direction, which is convenient for controlling and treating the water flow. The flow slowing plate 4, by being lower than the height of the spiral water guide channel 2, can slow down the water flow speed, allowing impurities in the water to have more time to settle to the bottom of the spiral water guide channel 2, while avoiding excessive impact on the subsequent filtration structure due to excessively fast water flow, thus improving the filtration effect and the stability of the device.
[0032] The inner wall of the spiral water guide channel 2 is connected to the vertically arranged overflow pipe 5 and the filter cylinder 6 respectively. The height of the filter cylinder 6 is lower than the height of the spiral water guide channel 2. The inner wall of the filter cylinder 6 is provided with a filter screen 7. The bottom of the spiral water guide channel 2 is provided with a drainage component 8.
[0033] When the water level in the spiral water guide trough 2 is too high, the excess water can be discharged through the overflow pipe 5 to prevent water from overflowing the spiral water guide trough 2, ensuring the normal operation of the device and avoiding the impact of excessive water level on the operation of other components or the waste of water resources. The filter cylinder 6, with its height lower than that of the spiral water guide trough 2, can utilize gravity to allow the pre-treated water to flow naturally into the filter cylinder 6, preparing for subsequent deep filtration. The filter screen 7 can perform deep filtration on the water flowing into the filter cylinder 6, removing impurities from the water, further improving water quality, and meeting different water use needs.
[0034] The drainage assembly 8 includes a water pump 81 installed inside the bracket 1. The water inlet end of the water pump 81 is connected to a water guide pipe 82, and the other end of the water guide pipe 82 is connected to the inner wall of the filter cylinder 6. A first electric valve 83 is provided on the outside of the water guide pipe 82, and the water outlet end of the water pump 81 is connected to a drain pipe 84.
[0035] The water pump 81 is configured to provide power to extract the filtered water from the filter cartridge 6 and transport it to the required location through the drain pipe 84, thereby realizing the functions of water extraction and transportation. The water guide pipe 82 serves as a channel for water to flow from the filter cartridge 6 into the water pump 81. The first electric valve 83 is configured to control the opening and closing of the water guide pipe 82, thereby controlling the water intake of the water pump 81. The water extraction and stopping can be flexibly adjusted according to actual needs. The drain pipe 84 is configured to transport the water extracted by the water pump 81 to a designated location to complete the water discharge or utilization.
[0036] Example 2:
[0037] This is the second embodiment of the present invention, which is based on the previous embodiment.
[0038] Specifically, the bottom of the spiral water guide channel 2 is connected to multiple sets of slag discharge pipes 9, and the positions of the multiple sets of slag discharge pipes 9 correspond to the positions of the multiple sets of flow slowing plates 4. The bottom end of the slag discharge pipe 9 is fitted with a sleeve 10, and two sets of clamping blocks 11 with left and right symmetrical design are provided on the outside of the sleeve 10.
[0039] The slag discharge pipe 9, connected to the bottom of the spiral water guide trough 2, is used to discharge impurities and dirt that have settled in the spiral water guide trough 2, keeping the spiral water guide trough 2 clean and ensuring the long-term stable operation and filtration effect of the device. The sleeve 10 serves as a transition component connecting the slag discharge pipe 9 and the material guide pipe 14, and also provides an installation position for the clamping block 11, the snap-fit seat 12, etc., to facilitate the control and management of the slag discharge process. The clamping block 11 is used to fix and support the snap-fit seat 12, and also provides a stable structural foundation for the installation and snap-fit of the clamp 13.
[0040] Specifically, each of the two sets of clamping blocks 11 has a locking seat 12 fixed on its outer side, and a clamp 13 is rotatably connected to the inner wall of the locking seat 12. The inner walls of the two sets of clamps 13 are respectively locked to the outer sides of the two sets of locking seats 12.
[0041] The clamp seat 12 can connect and fix the sleeve 10 and the guide pipe 14 by cooperating with the clamp 13. Through the clamping action of the clamp 13, the sleeve 10 and the guide pipe 14 are firmly connected together to prevent leakage during the slag discharge process and ensure the smooth progress of the slag discharge process.
[0042] Specifically, the inner wall of the sleeve 10 is connected to the guide pipe 14, and the outer side of the guide pipe 14 is provided with a second electric valve 15.
[0043] The guide pipe 14 serves as a channel for impurities to enter the discharge pipe 16 after being discharged from the slag discharge pipe 9. It is used to guide the impurities to the designated discharge position. The second electric valve 15 is used to control the opening and closing of the guide pipe 14, thereby controlling the discharge of impurities. The discharge time and flow rate can be flexibly adjusted according to the actual situation, which facilitates the automatic control of the discharge process.
[0044] Specifically, the bracket 1 has a horizontally installed discharge pipe 16 inside, and the inner wall of the discharge pipe 16 is connected to the end of the guide pipe 14 away from the sleeve 10. A flange 17 is provided at one end of the discharge pipe 16.
[0045] The discharge pipe 16 serves as a centralized channel for discharging impurities, collecting the impurities discharged from each slag discharge pipe 9 and discharging them from the device, facilitating unified treatment of the impurities. The flange 17 is used to connect other pipes or equipment, making it convenient to transport the impurities in the discharge pipe 16 to subsequent processing systems or storage devices, thereby improving the expandability and compatibility of the device.
[0046] Example 3:
[0047] This is the third embodiment of the present invention, which is based on the first two embodiments.
[0048] Specifically, the inlet of the spiral water guide channel 2 is connected to the water inlet hopper 18, and the inner wall of the water inlet hopper 18 is fixed with a filter plate 19.
[0049] The water inlet 18 serves as the water inlet of the device, connecting to the water inlet of the spiral water guide trough 2, facilitating the introduction of external water sources into the device. At the same time, its large opening area helps to improve the water intake efficiency. The filter plate 19 is used to perform preliminary filtration on the water source entering the device, intercepting larger particulate impurities, floating objects, etc., preventing these impurities from entering the spiral water guide trough 2 and affecting the normal operation and service life of the subsequent filtration structure, thus protecting the internal components of the device.
[0050] Specifically, a base 20 is provided on the outside of the bracket 1, and two sets of uprights 21 are installed on the top of the base 20. A solar panel 22 is installed on the top of the uprights 21.
[0051] The base 20 is set up to provide an installation foundation for the pole 21 and solar panel 22, ensuring the stable installation of the solar panel 22. At the same time, it arranges the components such as the solar panel 22 with the main body of the device in a reasonable manner. The pole 21 is set up to support the solar panel 22 and adjust the height and angle of the solar panel 22 so that it can better receive sunlight and improve the solar energy collection efficiency. The solar panel 22 is set up to convert solar energy into electrical energy, providing power support for electrical equipment such as the water pump 81, the first electric valve 83, and the second electric valve 15 in the device, so as to realize the energy-saving operation of the device.
[0052] Specifically, a sleeve 23 is installed at one end of the water pipe 82 away from the water pump 81 via a connecting flange, and multiple sets of RO permeation membranes 24 are provided on the inner wall of the sleeve 23.
[0053] The sleeve 23 provides installation space for multiple sets of ultrafiltration membranes or RO reverse osmosis membranes 24. Simultaneously, the connection flanges facilitate the removal of the fine filter cartridge 23 along with the ultrafiltration membranes or RO reverse osmosis membranes 24 mounted on its inner wall. This allows for easy cleaning or replacement of the ultrafiltration membranes or RO reverse osmosis membranes 24. The ultrafiltration membranes or RO reverse osmosis membranes enable deep filtration of the water flowing into the water pipe 82, removing organic impurities, bacteria, dissolved salt ions, harmful heavy metal ions, and other impurities, further improving water quality and meeting different water usage needs, such as drinking water and industrial water applications with high water quality requirements. It should be noted that sealing gaskets are installed between the connecting flanges to prevent leakage of filtered water during the process.
[0054] Working Principle: When this cascade sedimentation and water intake device is working, the water source first enters the inlet hopper 18, where it undergoes preliminary filtration through the filter plate 19 on its inner wall. This filters out larger particles and floating debris, preventing them from entering subsequent structures and affecting operation. The pre-filtered water flows into the spiral guide channel 2 and then along the guide cavity 3, which descends gradually along its inner wall. Multiple sets of flow-damping plates 4, fixed within the guide cavity 3, are lower than the spiral guide channel 2, slowing the water flow and allowing impurities more time to settle to the bottom of the spiral guide channel 2. The settled impurities are discharged through the slag discharge pipe 9, corresponding to the position of the flow-damping plate 4. The sleeve 10 at the bottom of the slag discharge pipe 9 is securely connected by a clamping block 11, a snap-fit seat 12, and a clamp 13. The guide pipe 14, connected to the inner wall of the sleeve 10, guides the impurities into the discharge pipe 16 under the control of the second electric valve 15, discharging them from the device. When the water level in the spiral guide channel 2 is too high, excess water is discharged. Water flows out through overflow pipe 5 to prevent overflow. The treated water flows naturally into filter cylinder 6 because the height of filter cylinder 6 is lower than that of spiral water guide channel 2. The filter screen 7 in the filter cylinder 6 performs deep filtration to remove impurities from the water. When water needs to be drawn, the first electric valve 83 is opened and the water pump 81 starts to work. The filtered water in filter cylinder 6 is drawn out through water guide pipe 82. At the same time, the water in water guide pipe 82 undergoes deep filtration through RO permeation membrane 24 in sleeve 23 to remove organic impurities, bacteria, dissolved salt ions, harmful heavy metal ions and other impurities from the water, further improving the water quality. The water is then transported to the designated location through drain pipe 84. In addition, the solar panel 22 installed on the top of the pole 21 on the outer base 20 of bracket 1 can convert solar energy into electrical energy to power the water pump 81, the first electric valve 83, the second electric valve 15 and other electrical equipment, realizing green electricity operation.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
