Description

Technical Field

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

[0002] Water quality monitoring and treatment have become increasingly important in modern society, especially in the context of water shortage and increasingly serious environmental pollution. Changes in water quality not only affect the natural ecosystem, but are also directly related to human health and quality of life. Suspended matter, as one of the important indicators in water quality testing, has a significant impact on the degree of water pollution and water cleanliness. Suspended matter usually includes silt and algae, which can significantly affect the transparency of water, oxygen solubility, and the living environment of aquatic organisms. At present, 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 matter in the water. Especially in an environment with large fluctuations in water quality, traditional detection methods are difficult to meet the needs of long-term stable monitoring. In order to better understand the water quality status and its changing trends, periodic collection of suspended matter in water has become an effective monitoring method.

[0003] Traditional suspended matter collection methods usually rely on manual sampling, which usually requires operators to personally go to water bodies such as pools and rivers to collect samples, which not only consumes a lot of time but also requires specific environmental conditions. Especially in larger water bodies such as pools and reservoirs, the selection of sampling points is often limited by manual evaluation, making it difficult to fully reflect the water quality conditions at various locations in the water body. In addition, frequent on-site sampling operations increase labor and time costs, and have low safety. Summary of the invention

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 8 The present invention provides a water quality detection and water supply device and a technical solution for use. The detailed connection means are well known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0019] A water quality detection water supply device and a method of use, comprising: a main pipeline 1, two valves 2, a secondary pipeline 3, a filter hole 31, a first drainage hole 32, a second drainage hole 33, a filter screen 4, a first drainage mechanism 6, a second drainage mechanism 7, an adjustment mechanism 8, a driving mechanism 9, a transmission shaft 10, an outer sleeve 11, an auxiliary sleeve 12 and a collecting 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 the water flow enters the secondary pipeline 3, and can be switched on and off as needed to adjust the water supply path. The setting of the two valves 2 ensures that flexible control can be performed under different water flow requirements, thereby improving the adjustability of the device. At the same time, a pressure differential valve and other structures, not shown in the figure, can be used to control the pressure difference between the secondary pipeline 3 and the main pipeline 1 The pressure difference ensures that the water flow can flow into the auxiliary pipeline 3 according to the set ratio and return to the main pipeline 1 smoothly. The two ends of the auxiliary pipeline 3 are connected to the main pipeline 1 through two valves 2. The auxiliary pipeline 3 is a branch of the main pipeline 1 and is responsible for guiding the water flow to the subsequent filtration and suspended matter collection position. The two ends of the auxiliary pipeline 3 are connected to the main pipeline 1 through two valves 2. The switch of the valve 2 controls whether the auxiliary pipeline 3 participates in the water flow circulation. The filter hole 31 is opened on the outer wall of the auxiliary pipeline 3 near the water outlet end. The filter hole 31 is located near the water outlet end of the auxiliary pipeline 3 and plays a role in filtering suspended matter in the water. As the water flows, the suspended matter is intercepted by the filter hole 31, and the water flows back to the auxiliary pipeline 3 through the filter hole 31. The first drainage hole 32 is opened circumferentially on the outer wall of the auxiliary pipeline 3 near the water inlet end. The second drainage hole 33 is opened on the auxiliary pipeline 3 along the circumferential direction and is located between the first drainage hole 32 and the filter hole 31. The first drainage hole 32 and the second drainage hole 33 are arranged at different positions of the auxiliary pipeline 3, and are respectively used to discharge impurities and water accumulated in the filtration system. When the water pressure exceeds the set threshold, the first drainage hole 32 and the second drainage hole 33 will be automatically opened. The filter screen 4 is rotatably installed in the inner cavity of the auxiliary pipeline 3 through the shaft rod 5. The filter screen 4 is located between the filter hole 31 and the second drainage hole 33. The two ends of the shaft rod 5 extend out of the outer wall of the auxiliary pipeline 3 respectively. The first drainage mechanism 6 is installed on the outer wall of the auxiliary pipeline 3 and corresponds to the first drainage hole 32. The second drainage mechanism 7 is installed on the outer wall of the auxiliary pipeline 3 and corresponds to the second drainage hole 33. The first drainage mechanism 6 and the second drainage mechanism 7 are respectively connected to the first drainage hole 32 and the second drainage hole 33 of the auxiliary pipeline 3, and can be automatically opened when the water flow pressure reaches the set threshold value. The automated design of the first drainage mechanism 6 and the second drainage mechanism 7 greatly reduces manual operation and improves the operation efficiency of the system. The regulating mechanism 8 is arranged on the outer wall of the auxiliary pipeline 3, and the regulating mechanism 8 is connected to one end of the shaft 5. The regulating mechanism 8 can adjust the water flow direction in the driving mechanism 9 when the filter screen 4 rotates to change the rotation direction of the filter screen 4 driven by the driving mechanism 9. The driving mechanism 9 is arranged on the outer wall of the auxiliary pipeline 3, and the driving mechanism 9 is connected to the other end of the shaft 5. The driving mechanism 9 can drive the filter screen 4 to rotate when the water pressure in the auxiliary pipeline 3 exceeds the threshold value of the first drainage mechanism 6.The transmission shaft 10 is radially arranged in the inner cavity of the auxiliary pipeline 3, and the two ends of the transmission shaft 10 are respectively connected to the adjustment mechanism 8 and the driving mechanism 9. The outer sleeve 11 is sleeved on the outside of the auxiliary pipeline 3. The end of the outer sleeve 11 pointing to the water inlet direction is 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 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. It can collect suspended matter to detect the water quality by observation or inspection.

[0020] More specifically, the rotation angle range of the filter 4 is between ±180 degrees. The rotation angle of the filter 4 is set to ±180 degrees, so that in each working cycle, the filter 4 can fully filter the water flowing through the filter 4 to avoid the occurrence of an angle between the axis of the filter 4 and the axis of the auxiliary pipeline 3. At the same time, a spring return booster device is provided at the position of the shaft 5, which is not shown in the figure. When the shaft 5 rotates more than 90 degrees, the spring energy storage is released, automatically pushing the shaft 5 to continue to rotate to 180 degrees.

[0021] More specifically, the inner cavity of the auxiliary pipeline 3 has an annular water flow guiding structure, which is not shown in the figure. The annular water flow guiding structure optimizes the flow direction of the water flow, so that the water flow can be evenly distributed in the auxiliary pipeline 3, and effectively avoids potential blockage or deposition caused by uneven water flow.

[0022] More specifically, the adjustment mechanism 8 includes: a first base 81, a first adjustment gear 82, a second adjustment gear 83, a second base 84, a third adjustment gear 85, a fourth adjustment 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 transmission shaft 10 passes through the end surface of the first base 81. This base provides a fixed position for the rotation of the transmission shaft 10, ensuring the stability and accuracy of the entire adjustment mechanism. The first adjustment gear 82 is arranged at the end of the transmission shaft 10, and the second adjustment gear 83 rotates. The first base 81 is rotatably arranged on the end surface 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. The shaft rod 5 rotates and passes through the end surface of the second base 84. The third adjusting gear 85 is arranged on the end of the shaft rod 5. The fourth adjusting gear 86 is rotatably arranged on the end surface 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.

[0023] Furthermore, the diameter of the fourth adjusting gear 86 is larger than the diameter of the third adjusting gear 85, and the diameter of the second adjusting gear 83 is smaller than the diameter of the first adjusting gear 82, so that when the filter 4 rotates within the range of ±180 degrees, the rotation range of the swing arm 87 connected to the fourth adjusting gear 86 is within ±90 degrees, and the rotation range of the other swing arm 87 is also within the range of ±90 degrees.

[0024] More specifically, the driving 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 driving gear 96, a housing 97, a second driving gear 98 and an impeller 99; the third base 91 is arranged on the outer wall of the auxiliary pipeline 3, the two-way rotary valve 92 is arranged 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 two-way rotary valve 92 is connected to the transmission shaft 10, which can realize two-way regulation of water flow, and the two-way rotary valve 92 can control the flow direction of water according to demand, and one end of the water inlet pipe 93 is connected to the two-way rotary valve The second water outlet pipe 94 is connected to the water inlet of the auxiliary sleeve 12, and the other end of the water inlet pipe 93 is connected to the auxiliary sleeve 12 and extends to 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 arranged on the outer wall of the auxiliary pipeline 3. The shaft rod 5 rotates and passes through the end face of the fourth base 95. The first driving gear 96 is arranged at the end of the shaft rod 5. The shell 97 is arranged on the fourth base 95 through the bracket interval. The shell 97 is arranged between the two water outlet pipes 94. The second driving gear 98 is rotatably arranged on the fourth base 95. The impeller 99 is rotatably arranged in the shell 97, and the impeller 99 rotates synchronously with the second driving gear 98.

[0025] Furthermore, the water outlet routes of the two water outlet pipes 94 in the shell 97 are parallel and symmetrically located on both sides of the axis of the shell 97. Through this parallel design, the forward or reverse rotation of the impeller 99 can be achieved by separately controlling the opening and closing of the two water outlet pipes 94, so that 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, and when the second water outlet pipe 94 discharges water and the first water outlet pipe 94 does not discharge water, the impeller 99 reverses.

[0026] Furthermore, the shell 97 has two water inlets and two water outlets on both sides, and each is provided with a one-way valve, which can effectively prevent the water from flowing back, ensure the one-way flow of the water, and avoid unnecessary backflow problems.

[0027] More specifically, the collecting device 13 includes: two collecting covers 131 and a binding belt 132. The two collecting covers 131 are two identical annular shells. The two collecting 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 allows the entire device to be easily disassembled. 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. Suspended matter flowing between the outer sleeve 11 and the auxiliary pipeline 3 can enter the annular structure, and the suspended matter can be removed by disassembling the annular structure. Collection and detection, when the two collecting hoods 131 are installed on the outer sleeve 11, the straps 132 can be used to wrap around the outer walls of the two collecting hoods 131. The use of the straps 132 can enhance the connection stability between the collecting hoods 131 and the outer sleeve 11 to avoid loosening or deformation under high water pressure or long-term use. The straps 132 can effectively fix the two collecting hoods 131 to ensure that they always maintain the correct position and angle during the collection process, thereby improving the work efficiency and safety of the entire system. At the same time, the collecting hoods 131 are made of transparent material, and the collected suspended matter can be visually observed.

[0028] More specifically, the first drainage mechanism 6 and the second drainage mechanism 7 have the same structure, both of which are composed of a fixing ring 61, a flap 62 and a reed 63. A through groove is opened on the annular outer wall of the fixing ring 61, which corresponds to the first drainage hole 32 and the second drainage hole 33 respectively. One end of the flap 62 is hinged to one side of the through groove, one end of the reed 63 is arranged on the outer wall of the flap 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 of the second drainage mechanism 7 is arranged on the inner wall of the auxiliary sleeve 12, and 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 first drainage mechanism 6 and the second drainage mechanism 7 have the same structure, which ensures the interchangeability and consistency of the two drainage mechanisms, so that the entire device has a high degree of repeatability and stability in function.

[0029] More specifically, a cleaning device 14 is also provided on the auxiliary pipeline 3, and 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 provided on the outer wall of the auxiliary pipeline 3, and the axis of the power ring 141 is colinear with the axis of the auxiliary pipeline 3, and the scraper 142 is provided on the power ring 141, and the edge of the scraper 142 is attached to the outer wall of the auxiliary pipeline 3 and corresponds to the position of the filter hole 31. The rotation of the power ring 141 drives the scraper 142 to rotate on the outer wall of the auxiliary pipeline 3, so as to scrape off the suspended matter on the filter hole 31, and at the same time push the suspended matter to move toward the collecting mechanism, so as to cause the suspended matter to move to the collecting mechanism. In the collecting mechanism, the base 143 is arranged at the bottom end of the inner wall of the auxiliary pipeline 3. 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 rotatably arranged on the base 143 respectively and mesh with each other. The second cleaning gear 145 penetrates the outer wall of the auxiliary pipeline 3 and meshes with the inner wall of the power ring 141. The paddle 146 is installed on the first cleaning gear 144. The axis of the paddle 146 is parallel to the axis of the auxiliary pipeline 3. The paddle 146 is driven by the water flow, and the rotation of the scraper 142 is driven by the transmission of the first cleaning gear 144 and the second cleaning gear 145. 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.

[0030] S1. Open the two valves 2 to allow part of the water flow in the main pipeline 1 to flow through the secondary pipeline 3; S2. The initial water flows back to the main pipeline 1 through the filter 4. As the filter 4 is gradually blocked, the water pressure between the filter 4 and the water inlet end of the auxiliary pipeline 3 gradually increases; S3. When the water pressure exceeds the threshold of the second drainage mechanism 7, the second drainage mechanism 7 is opened, the water flows between the outer casing 11 and the auxiliary pipeline 3, the suspended matter is located between the outer casing 11 and the auxiliary pipeline 3, and moves to the collecting device 13 under the action of the water flow, and the water flows back to the inner cavity of the auxiliary pipeline 3 through the filter hole 31; S4. When the blockage area of ​​the filter 4 is too large, the water pressure between the filter 4 and the water inlet end of the auxiliary pipeline 3 gradually increases, and when it exceeds the threshold of the first drainage mechanism 6, the first drainage mechanism 6 opens, and part of the water flows into the driving mechanism 9, driving the filter 4 to rotate 180 degrees; S5. At this time, under the action of water pressure, the impurities on the filter 4 are removed, and the water pressure between the filter 4 and the water inlet end of the auxiliary pipeline 3 is lower than the threshold of the first drainage mechanism 6. The first drainage mechanism 6 is closed, and at the same time, under the action of the adjustment mechanism 8, the next driving direction of the driving mechanism 9 is changed to complete a working cycle.

[0031] The specific working principle is as follows: If no test is performed, close the valve between the main pipeline 1 and the auxiliary pipeline 3, and the water will be discharged from the main pipeline 1; When testing is required, open the two valves 2 and part of the water will flow into the auxiliary pipeline 3. The water will flow through the filter screen 4 in the auxiliary pipeline 3 and flow back to the main pipeline 1. In this process, if the water quality is good, no suspended matter will be collected in the collection device 13 for a long time. If the water quality is poor, more suspended matter will appear in the collection device 13 in a short time. The preliminary test results can be achieved through the periodic observation structure. When the water quality is poor, the suspended matter gradually blocks the filter screen 4, the resistance of water flow increases, 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 flows into the interlayer between the outer sleeve 11 and the auxiliary pipeline 3 through the second drainage hole 33, and part of the water flows back to the main pipeline 1 through the auxiliary pipeline 3. The water flowing through the interlayer flows back to the auxiliary pipeline 3 through the filter hole 31, and the suspended matter The water in the filter screen 4 is filtered in the interlayer, and the paddle 146 is driven to rotate by the water flowing through the auxiliary pipeline 3, and the scraper 142 is driven to rotate around the auxiliary pipeline 3 to scrape off the suspended matter filtered at the filter hole 31 and push it into the collecting device 13. When the filter screen 4 is gradually blocked more and more seriously, 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 is opened, and the corresponding reed 63 is compressed. At this time, the water will enter the auxiliary sleeve 12. The inner cavity of the filter screen 4 is filled with water, and enters a water outlet pipe 94 through the water inlet pipe 93 and the two-way rotary valve 92, and enters the housing 97 to drive the impeller 99 to rotate forward, and through the transmission of the first drive gear 96 and the second drive gear 98, the shaft 5 is driven to rotate until the filter screen 4 rotates 180 degrees. At this time, the side of the filter screen 4 that blocks the suspended matter rotates to the downstream direction. Under the impact of water pressure, the suspended matter is washed away.
