Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to a water quality detection water supply device and a using method thereof. Background Art

[0002] Water quality monitoring and treatment have become increasingly important in modern society. Especially in the context of water resource shortage and increasingly serious environmental pollution, the change of water quality not only affects the natural ecosystem, but also directly relates to human health and quality of life. Suspended solids, as one of the important indicators in water quality detection, have an important impact on the pollution degree and water quality cleanliness of water bodies. Suspended solids usually include sediment, algae, etc., which can significantly affect the transparency of water bodies, the solubility of oxygen, and the living environment of organisms in water;

[0003] Currently, water quality monitoring mostly relies on real-time monitoring equipment and chemical reagent analysis. Although these methods can provide relatively accurate water quality data, they often ignore the dynamic changes of suspended solids in water. Especially in an environment with large water quality fluctuations, traditional detection methods are difficult to meet the requirements of long-term stable monitoring. In order to better grasp the water quality status and its change trend, collecting suspended solids in water periodically has become an effective monitoring means.

[0004] Traditional methods for collecting suspended solids usually rely on manual sampling. Manual sampling usually requires operators to go to the site of water bodies such as pools and rivers to take samples in person. This not only consumes a large amount of time, but also requires specific environmental conditions. Especially in large-scale water bodies such as pools and reservoirs, the selection of sampling points is often restricted by manual evaluation and it is difficult to comprehensively reflect the water quality status at various positions in the water body. In addition, frequent on-site sampling operations increase the labor cost and time cost, and the safety is low. Summary of the Invention

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-8 , the present invention provides a technical solution for a water quality detection water supply device and a usage method. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0032] A water quality detection water supply device and its usage method, comprising: a main pipeline 1, two valves 2, a secondary pipeline 3, filter holes 31, a first drain hole 32, a second drain hole 33, a filter screen 4, a first drainage mechanism 6, a second drainage mechanism 7, an adjustment mechanism 8, a drive mechanism 9, a transmission shaft 10, an outer sleeve 11, an auxiliary sleeve 12, and a collection device 13; The main pipeline 1 is responsible for introducing water into the entire system, and the two valves 2 are used to control whether water flows into the secondary pipeline 3. They can be operated to open or close according to needs to adjust the water supply path. The setting of these two valves 2 ensures flexible control under different water flow requirements, improving the adjustability of the device. At the same time, by using structures such as pressure difference valves, not shown in the figure, the pressure difference between the secondary pipeline 3 and the main pipeline 1 can be controlled to ensure that water can flow into the secondary pipeline 3 according to a set ratio and return smoothly to the main pipeline 1. The two ends of the secondary pipeline 3 are connected to the main pipeline 1 through two valves 2. The secondary pipeline 3, as a branch of the main pipeline 1, is responsible for guiding water flow to subsequent filtration and suspended matter collection positions. The two ends of the secondary pipeline 3 are connected to the main pipeline 1 through two valves 2, and the opening and closing of the valves 2 control whether the secondary pipeline 3 participates in the water flow cycle. The filter holes 31 are opened on the outer wall of the secondary pipeline 3 near the water outlet end. The filter holes 31 are located at the water outlet end of the secondary pipeline 3 and play a role in filtering suspended matter in the water. As the water flows, the suspended matter is intercepted by the filter holes 31, and the water flows back into the interior of the secondary pipeline 3 through the filter holes 31. The first drain hole 32 is circumferentially opened on the outer wall of the secondary pipeline 3 near the water inlet end. The second drain hole 33 is circumferentially opened on the secondary pipeline 3 and is located between the first drain hole 32 and the filter holes 31. The first drain hole 32 and the second drain hole 33 are set at different positions on the secondary pipeline 3 and are respectively used to discharge impurities and water flow accumulated in the filtration system. When the water pressure exceeds the set threshold, the first drain hole 32 and the second drain hole 33 will automatically open. The filter screen 4 is rotatably installed in the inner cavity of the secondary pipeline 3 through a shaft rod 5. The filter screen 4 is located between the filter holes 31 and the second drain hole 33. The two ends of the shaft rod 5 respectively extend out of the outer wall of the secondary pipeline 3. The first drainage mechanism 6 is installed on the outer wall of the secondary pipeline 3 and corresponds to the first drain hole 32. The second drainage mechanism 7 is installed on the outer wall of the secondary pipeline 3 and corresponds to the second drain hole 33. The first drainage mechanism 6 and the second drainage mechanism 7 are respectively connected to the first drain hole 32 and the second drain hole 33 of the secondary pipeline 3 and can automatically open when the water flow pressure reaches the set threshold. The automated design of the first drainage mechanism 6 and the second drainage mechanism 7 greatly reduces manual operation and improves the operating efficiency of the system. The adjustment mechanism 8 is set on the outer wall of the secondary pipeline 3, and the adjustment mechanism 8 is connected to one end of the shaft rod 5. The adjustment mechanism 8 can adjust the water flow direction in the drive mechanism 9 when the filter screen 4 rotates to change the rotation direction of the drive mechanism 9 driving the filter screen 4. The drive mechanism 9 is set on the outer wall of the secondary pipeline 3, and the drive mechanism 9 is connected to the other end of the shaft rod 5. The drive mechanism 9 can drive the filter screen 4 to rotate when the water pressure in the secondary pipeline 3 exceeds the threshold of the first drainage mechanism 6.The drive shaft 10 is radially arranged in the inner cavity of the auxiliary pipeline 3 along the radial direction of the auxiliary pipeline 3, and both ends of the drive shaft 10 are respectively connected to the adjusting mechanism 8 and the driving mechanism 9. The outer sleeve 11 is sleeved on the outside of the auxiliary pipeline 3. One end of the outer sleeve 11 pointing to the water inlet direction is of a variable diameter structure and is connected to the outer wall of the auxiliary pipeline 3. The other end of the outer sleeve 11 is of an open structure. The auxiliary sleeve 12 is arranged on the outside of the first drainage mechanism 6 and is connected to the auxiliary pipeline 3. A closed chamber is formed between the auxiliary sleeve 12 and the outer wall of the auxiliary pipeline 3. When the first drainage mechanism 6 is opened, the liquid will enter between the auxiliary sleeve 12 and the auxiliary pipeline 3. The collection device 13 is sleeved on the outer wall of the main pipeline 1 and is detachably connected to the outer sleeve 11, and can collect suspended matter for detecting the water quality by means of observation or inspection, etc.

[0033] More specifically, the rotation angle range of the filter screen 4 is between ±180 degrees, and the rotation angle of the filter screen 4 is set to ±180 degrees, so that in each working cycle, the filter screen 4 can fully filter the water flow passing through the filter screen 4, avoiding an angle between the axis of the filter screen 4 and the axis of the auxiliary pipeline 3. At the same time, a spring reset boosting device (not shown in the figure) is arranged at the position of the shaft rod 5. When the shaft rod 5 rotates more than 90 degrees, the spring energy storage is released, automatically pushing the shaft rod 5 to continue rotating to 180 degrees.

[0034] More specifically, the inner cavity of the auxiliary pipeline 3 has an annular water flow guiding structure (not shown in the figure). The annular water flow guiding structure optimizes the flow direction of the water flow, enables the water flow to be evenly distributed in the auxiliary pipeline 3, and effectively avoids potential blockage or deposition caused by uneven water flow.

[0035] More specifically, the adjusting mechanism 8 includes: a first base 81, a first adjusting gear 82, a second adjusting gear 83, a second base 84, a third adjusting gear 85, a fourth adjusting gear 86, two swing arms 87 and a connecting arm 88; the first base 81 is arranged on the outer wall of the auxiliary pipeline 3, and the rotation of the drive shaft 10 penetrates through the end face of the first base 81. This base provides a fixed position for the rotation of the drive shaft 10, ensuring the stability and accuracy of the entire adjustment mechanism. The first adjusting gear 82 is arranged at the end of the drive shaft 10. The second adjusting gear 83 is rotatably arranged on the end face of the first base 81 and meshes with the first adjusting gear 82. The second base 84 is arranged on the outer wall of the auxiliary pipeline 3, and the shaft rod 5 rotates through the end face of the second base 84. The third adjusting gear 85 is arranged at the end of the shaft rod 5. The fourth adjusting gear 86 is rotatably arranged on the end face of the second base 84 and meshes with the third adjusting gear 85. One end of a swing arm 87 is connected to the second adjusting gear 83, and one end of the other swing arm 87 is connected to the fourth adjusting gear 86. The two ends of the connecting arm 88 are respectively connected to the two swing arms 87.

[0036] Further, the diameter of the fourth adjusting gear 86 is larger than that of the third adjusting gear 85, and the diameter of the second adjusting gear 83 is smaller than that of the first adjusting gear 82. When the filter screen 4 rotates within a range of ±180 degrees, the swing arm 87 connected to the fourth adjusting gear 86 rotates within a range of ±90 degrees, and at the same time, the rotation range of the other swing arm 87 is also within a range of ±90 degrees.

[0037] More specifically, the drive mechanism 9 includes: a third base 91, a two-way rotary valve 92, a water inlet pipe 93, two water outlet pipes 94, a fourth base 95, a first drive gear 96, a housing 97, a second drive gear 98, and an impeller 99; the third base 91 is disposed on the outer wall of the secondary pipeline 3, the two-way rotary valve 92 is disposed on the third base 91, the valve stem of the two-way rotary valve 92 is connected to the transmission shaft 10, the third base 91 provides stable support, and the connection between the two-way rotary valve 92 and the transmission shaft 10 enables two-way adjustment of the water flow. The two-way rotary valve 92 can control the water flow direction according to requirements. One end of the water inlet pipe 93 is connected to the water inlet of the two-way rotary valve 92, and the other end of the water inlet pipe 93 is connected to the auxiliary sleeve 12 and extends into the inner cavity of the auxiliary sleeve 12. The two water outlet pipes 94 are respectively connected to the two water outlet ends of the two-way rotary valve 92. The fourth base 95 is disposed on the outer wall of the secondary pipeline 3. The shaft rod 5 rotates through the end face of the fourth base 95. The first drive gear 96 is disposed at the end of the shaft rod 5. The housing 97 is disposed on the fourth base 95 at intervals through a bracket. The housing 97 is disposed between the two water outlet pipes 94. The second drive gear 98 is rotatably disposed on the fourth base 95. The impeller 99 is rotatably disposed in the housing 97, and the impeller 99 rotates synchronously with the second drive gear 98.

[0038] Further, the water outlet routes of the two water outlet pipes 94 in the housing 97 are parallel and symmetrically located on both sides of the axis of the housing 97. Through this parallel design, the forward or reverse rotation of the impeller 99 can be achieved by respectively controlling the opening and closing of the two water outlet pipes 94. When the first water outlet pipe 94 discharges water and the second water outlet pipe 94 does not discharge water, the impeller 99 rotates forward. When the second water outlet pipe 94 discharges water and the first water outlet pipe 94 does not discharge water, the impeller 99 rotates in reverse.

[0039] Further, both sides of the housing 97 are provided with two water inlets and two water outlets, and one-way valves are respectively provided, which can effectively prevent the backflow of water, ensure the unidirectional flow of water, and avoid unnecessary backflow problems.

[0040] More specifically, the collection device 13 includes: two collection covers 131 and a strap 132. The two collection covers 131 are two identical annular shells. The two collection covers 131 are symmetrically installed to form a complete annular structure. When it is necessary to collect and detect suspended matter, the detachable feature of the annular structure enables the entire device to be disassembled conveniently. Moreover, the side wall of the annular structure is an open structure, which can be detachably connected to the open structure of the outer sleeve 11. The suspended matter flowing between the outer sleeve 11 and the secondary pipeline 3 can enter this annular structure. The suspended matter is collected and detected by disassembling the annular structure. When the two collection covers 131 are installed on the outer sleeve 11, the strap 132 can be used to wind around the outer walls of the two collection covers 131. The use of the strap 132 can enhance the connection stability between the collection cover 131 and the outer sleeve 11, avoiding loosening or deformation under high water pressure or long-term use. The strap 132 can effectively fix the two collection covers 131, ensuring that they always maintain the correct position and angle during the collection process, improving the working efficiency and safety of the entire system. At the same time, the collection cover 131 is made of a transparent material, and the situation of the collected suspended matter can be observed visually.

[0041] More specifically, the first drainage mechanism 6 and the second drainage mechanism 7 have the same structure, and both are composed of a fixed ring 61, a flip cover 62 and a reed 63. Through grooves are formed on the annular outer wall of the fixed ring 61, corresponding to the first drainage hole 32 and the second drainage hole 33 respectively. One end of the flip cover 62 is hinged to one side of the through groove. One end of the reed 63 is arranged on the outer wall of the flip cover 62. The other end of the reed 63 in the first drainage mechanism 6 is arranged on the inner wall of the outer sleeve 11, and the other end of the reed 63 in the second drainage mechanism 7 is arranged on the inner wall of the auxiliary sleeve 12. Moreover, the elastic coefficient of the reed 63 in the first drainage mechanism 6 is greater than that of the reed 63 in the second drainage mechanism 7. The same structure of the first drainage mechanism 6 and the second drainage mechanism 7 ensures the interchangeability and consistency of the two drainage mechanisms, making the entire device highly repeatable and stable in function.

[0042] More specifically, a cleaning device 14 is also provided on the secondary pipeline 3. The cleaning device 14 includes: a power ring 141, a scraper 142, a base 143, a first cleaning gear 144, a second cleaning gear 145, and a paddle 146. The power ring 141 is rotatably arranged on the outer wall of the secondary pipeline 3, and the axis of the power ring 141 is collinear with the axis of the secondary pipeline 3. The scraper 142 is arranged on the power ring 141, and the edge of the scraper 142 fits against the outer wall of the secondary pipeline 3 and corresponds to the position of the filter holes 31. By using the rotation of the power ring 141 to drive the scraper 142 to rotate on the outer wall of the secondary pipeline 3, the suspended matter on the filter holes 31 is scraped off, and at the same time, the suspended matter is pushed towards the collection mechanism, prompting the suspended matter to move into the collection mechanism. The base 143 is arranged at the bottom end of the inner wall of the secondary pipeline 3, and the shape of the base 143 meets the requirement of reducing water resistance. The first cleaning gear 144 and the second cleaning gear 145 are respectively rotatably arranged on the base 143 and are meshed with each other. The second cleaning gear 145 penetrates the outer wall of the secondary pipeline 3 and is meshed with the inner wall of the power ring 141. The paddle 146 is installed on the first cleaning gear 144, and the axis of the paddle 146 is parallel to the axis of the secondary pipeline 3. The paddle 146 is driven by the water flow, and through the transmission of the first cleaning gear 144 and the second cleaning gear 145, the rotation of the scraper 142 is driven. At the same time, the diameter of the first cleaning gear 144 is smaller than that of the second cleaning gear 145 to provide a larger torque.

[0043] S1. Open the two valves 2 so that part of the water flow in the main pipeline 1 flows through the secondary pipeline 3.

[0044] S2. The initial water flow flows back into the main pipeline 1 through the filter screen 4. As the filter screen 4 is gradually blocked, the water pressure between the filter screen 4 and the water inlet end of the secondary pipeline 3 gradually increases.

[0045] S3. When the water pressure exceeds the threshold of the second drainage mechanism 7, the second drainage mechanism 7 opens, and the water flow flows between the outer sleeve 11 and the secondary pipeline 3. The suspended matter is between the outer sleeve 11 and the secondary pipeline 3 and moves into the collection device 13 under the action of the water flow. The water flow flows back into the inner cavity of the secondary pipeline 3 through the filter holes 31.

[0046] S4. When the blocked area of the filter screen 4 is too large and the water pressure between the filter screen 4 and the water inlet end of the secondary pipeline 3 gradually increases and exceeds the threshold of the first drainage mechanism 6, the first drainage mechanism 6 opens, and part of the water flow enters the driving mechanism 9 to drive the filter screen 4 to rotate 180 degrees.

[0047] S5. At this time, under the action of the water pressure, the impurities on the filter screen 4 are removed, the water pressure between the filter screen 4 and the water inlet end of the secondary pipeline 3 is lower than the threshold of the first drainage mechanism 6, the first drainage mechanism 6 closes, and at the same time, under the action of the adjusting mechanism 8, the next driving direction of the driving mechanism 9 is changed, completing a working cycle.

[0048] The specific working principle is as follows:

[0049] If no detection is carried out, the valve between the main pipeline 1 and the auxiliary pipeline 3 is closed, and the water flow will be entirely discharged from the main pipeline 1.

[0050] When detection is required, the two valves 2 are opened, and part of the water flow will flow into the auxiliary pipeline 3. The water flow flows through the filter screen 4 in the auxiliary pipeline 3 and then returns to the main pipeline 1. During this process, if the water quality is good, no suspended matter will be collected in the long-term collection device 13 for a long time. If the water quality is poor, more suspended matter will appear in the short-term collection device 13, and the preliminary detection result can be achieved by observing the structure periodically.

[0051] When the water quality is poor, the suspended matter gradually clogs the filter screen 4, the resistance of the water flow through it becomes larger, and the water pressure between the filter screen 4 and the water inlet end of the auxiliary pipeline 3 gradually increases. When the water pressure exceeds the threshold of the second drainage mechanism 7, the flap 62 of the second drainage mechanism 7 opens, and the corresponding reed 63 is compressed. At this time, part of the water flow enters the interlayer between the outer sleeve 11 and the auxiliary pipeline 3 through the second drainage hole 33, and part of the water flow returns to the main pipeline 1 through the auxiliary pipeline 3. The water flow passing through the interlayer returns to the auxiliary pipeline 3 through the filter holes 31, and the suspended matter is filtered in the interlayer. This process repeats. At the same time, the paddle 146 is driven to rotate by the water flow passing through the auxiliary pipeline 3, and drives the scraper 142 to rotate around the auxiliary pipeline 3 to scrape the suspended matter filtered at the position of the filter holes 31 and push it into the collection device 13. When the filter screen 4 is gradually blocked more and more severely, and the water pressure between the filter screen 4 and the water inlet end of the auxiliary pipeline 3 exceeds the first drainage mechanism 6, the flap 62 of the first drainage mechanism 6 opens, and the corresponding reed 63 is compressed. At this time, the water flow will enter the inner cavity of the auxiliary sleeve 12, and enter a water outlet pipe 94 through the water inlet pipe 93 and the bidirectional rotary valve 92, and enter the housing 97 to drive the impeller 99 to rotate forward. Through the transmission of the first driving gear 96 and the second driving gear 98, the shaft rod 5 is driven to rotate until the filter screen 4 rotates 180 degrees. At this time, the side of the filter screen 4 blocked by the suspended matter rotates to the downstream direction. Under the impact of the water pressure, the suspended matter is washed off. At this time, the water pressure between the filter screen 4 and the water inlet end of the auxiliary pipeline 3 returns to normal, and both the first drainage mechanism 6 and the second drainage mechanism 7 are closed. At the same time, the shaft rod 5 rotates 180 degrees. Through the cooperation of the first adjusting gear 82, the second adjusting gear 83, the third adjusting gear 85, the fourth adjusting gear 86, the two swing arms 87 and the connecting arm 88, the drive transmission shaft 10 is rotated, thereby adjusting the bidirectional rotary valve 92, so that the water flow is drained through the other water outlet pipe 94 next time, and the filter screen 4 rotates 180 degrees in the reverse direction. The water discharged from the water outlet pipe 94 can be discharged to the outside, or a separate water collecting bucket can be set up to complete a single operation.
