Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring, and in particular to a device for monitoring water quality filtration in channels. Background Technology

[0002] In the daily operation and maintenance of waterways, floating debris, silt, and other impurities in the water can damage the normal water flow and related equipment. Currently common filtration methods often fail to effectively classify and filter impurities of different sizes, resulting in poor filtration performance. Furthermore, monitoring of filtration device blockage and water flow within the channel is not timely or accurate enough; blockages are often only discovered after they have severely affected water flow. When a filter becomes clogged, workers may need to disassemble the entire device to remove impurities and blockages. Excessive force during disassembly can deform filter components, shortening the filter's lifespan, increasing labor costs, and reducing overall system efficiency. This significantly impacts the normal operation of the channel, requiring substantial manpower and resources for cleaning and repair, thus increasing operating costs. Therefore, we propose a water quality filtration and monitoring device for waterways to address these issues. Utility Model Content

[0003] This utility model provides a channel water quality filtration and monitoring device, which solves the problem that it is impossible to effectively filter impurities of different sizes. Workers may need to disassemble the entire device to remove impurities and blockages from the filter. Excessive force during disassembly may cause deformation of filter components, thereby shortening the service life of the filtration device and increasing labor costs.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a channel water quality filtration and monitoring device, including a channel, a lifting filtration device on the channel, the filtration device including a first filter plate and a second filter plate, a dredging plate between the first filter plate and the second filter plate, two screws at both ends of the dredging plate, and two push frames on one side of the first filter plate, the push frames being connected to the screws.

[0005] In a preferred embodiment, the aperture of the first filter plate is larger than that of the second filter plate, the first filter plate has two first through holes on both sides, and the bottom of the first filter plate has a slag collection trough.

[0006] In the preferred embodiment, the second filter plate has second through holes on both sides, and a water pipe is provided on one side of the second filter plate, with a flow sensor installed on the water pipe.

[0007] In a preferred embodiment, the filtration device includes two U-shaped plates that abut against the ends of the first and second filter plates.

[0008] In the preferred embodiment, vertical sliding grooves are provided on both sides of the channel, and multiple guide wheels are provided on the U-shaped plate. The guide wheels abut against the vertical sliding grooves, and the two sides of the U-shaped plate abut against the vertical sliding grooves.

[0009] In the preferred embodiment, the drain plate includes a grid with multiple drain columns and two threaded holes at both ends, which are connected to screws.

[0010] In a preferred embodiment, the pusher frame includes a U-shaped frame with third through holes at both ends. The screw passes through the third through hole, and the screw also passes through the first through hole and the second through hole.

[0011] In the preferred embodiment, the push frame is provided with two nuts, which are connected to the screw, and a second nut is provided at the other end of the nuts.

[0012] In the preferred embodiment, a support is provided at the top of the channel, a winch is provided on the support, the winch is connected to the filter device via a steel cable, and an ultrasonic detector is provided on the filter device.

[0013] The beneficial effects of this invention are as follows: When the entire device is in operation, the winch is driven to rewind the filter, allowing it to slide along the vertical groove of the channel to the bottom. A flow sensor is installed on the water pipe of the second filter plate. The pore size of the first filter plate is larger than that of the second filter plate. The first filter plate is mainly used to intercept larger floating debris, while the second filter plate further filters out fine particles such as silt. The two filter screens form a graded filtration structure, improving the filtration effect and ensuring that the water entering the subsequent part of the channel is relatively clean.

[0014] An ultrasonic detector and a flow sensor are installed on the filter unit. The ultrasonic detector accurately measures the thickness of the sediment on the filter plate by emitting and receiving ultrasonic signals. The flow sensor monitors the water flow rate through the water pipe in real time. When the filter unit is used for a period of time for regular maintenance or when the flow sensor reading is below the threshold, the winch is activated to lift the filter unit. The second nut is rotated to move it away from the second filter plate, pulling the two pushers to move the cleaning plate relative to the first filter plate, allowing the cleaning column to penetrate the filter holes on the first filter plate. After the first filter plate is cleaned, the nut is rotated to move it away from the first filter plate, pushing the pushers to allow the cleaning column to penetrate the filter holes on the second filter plate. After the first filter plate is cleaned, the pushers are moved to reset the cleaning plate. The nut and the second nut are rotated to reset them, fixing the cleaning plate in place. After the entire device is cleaned, the winch is activated to position the filter unit at the bottom of the channel. The overall structure is simple, enabling quick and effective unclogging of the first and second filter plates, preventing blockages. During unclogging, workers do not need to disassemble the entire device, avoiding excessive force that could deform filter components and shorten the filter's lifespan. Unclogging only requires adjusting the nut, the second nut, and the pusher frame, making it simple, quick, practical, and cost-effective. It avoids the need for extensive manpower and resources for cleaning and maintenance during filter unclogging, making it highly valuable for widespread adoption. Attached Figure Description

Detailed Implementation

[0026] Example 1:

[0027] like Figure 1-9 The device for monitoring and filtering water quality in a channel includes a channel 14. A lifting filter device 1 is installed on the channel 14. The filter device 1 includes a first filter plate 2 and a second filter plate 3. A clearing plate 4 is located between the first filter plate 2 and the second filter plate 3. Two screws 7 are located at both ends of the clearing plate 4. Two push frames 6 are located on one side of the first filter plate 2, and the push frames 6 are connected to the screws 7. With this structure, when the entire device is in operation, a winch 13 is driven to rewind the filter device 1, allowing it to slide along the vertical groove of the channel 14 to the bottom of the channel 14. A flow sensor 10 is installed on the water pipe 302 on the second filter plate 3. The pore size of the first filter plate 2 is larger than that of the second filter plate 3. The first filter plate 2 is mainly used to intercept larger floating debris, while the second filter plate 3 further filters fine particles such as silt. The two filter screens form a graded filtration structure, improving the filtration effect and ensuring that the water entering the subsequent part of the channel is relatively clean.

[0028] An ultrasonic detector 11 and a flow sensor 10 are installed on the filter device 1. The ultrasonic detector 11 can accurately measure the thickness of the sediment on the filter plate by emitting and receiving ultrasonic signals. The flow sensor 10 monitors the water flow rate through the water pipe 302 in real time. When the filter device 1 is used for a period of time for regular maintenance or when the value of the flow sensor 10 is less than the threshold, the winch 13 is driven to lift the filter device 1. The second nut 15 is rotated to move the second nut 15 away from the second filter plate 3, and the two pushers 6 are pulled to move the unclogging plate 4 relative to the first filter plate 2, so that the unclogging column 402 passes through the filter holes on the first filter plate 2. After the first filter plate 2 is cleaned. Rotate nut 8 to move it away from the first filter plate 2, and push the pusher 6 to allow the unblocking column 402 to pass through the filter holes on the second filter plate 3. After the first filter plate 2 is cleaned, move the pusher 6 to reset the unblocking plate 4. Rotate nut 8 and the second nut 15 to reset them and fix the unblocking plate 4. After the entire device is cleaned, drive the winch 13 to position the filter device 1 at the bottom of the channel 14. The overall structure is simple and can quickly and effectively unclog the first filter plate 2 and the second filter plate 3, preventing blockage. During the unblocking process, the operator does not need to disassemble the entire device, avoiding excessive force during disassembly or deformation of filter components, which could shorten the service life of the filter device. During the unblocking process, only nut 8, the second nut 15, and the pusher 6 need to be adjusted. The operation is simple and quick, highly practical, and has low labor costs, avoiding the need for a lot of manpower and resources to clean and maintain the filter device 1.

[0029] In the preferred embodiment, the aperture of the first filter plate 2 is larger than that of the second filter plate 3. The first filter plate 2 has two first through holes 201 on both sides, and a sludge collection trough 202 at its bottom. With this structure, the sludge collection trough 202 at the bottom of the first filter plate 2 is used to collect larger volume floating debris. When the filter device 1 is lifted, the floating debris blocked by the first filter plate 2 collects on the sludge collection trough 202. Workers then clean the floating debris on the sludge collection trough 202 to ensure the clarity of the water quality in the later stages.

[0030] In a preferred embodiment, the second filter plate 3 has second through holes 301 on both sides, and a water pipe 302 is provided on one side of the second filter plate 3. A flow sensor 10 is installed on the water pipe 302. With this structure, an ultrasonic detector 11 and a flow sensor 10 are installed on the filter device 1. The ultrasonic detector 11 can accurately measure the thickness of the sediment on the filter plate by emitting and receiving ultrasonic signals. The flow sensor 10 monitors the water flow rate through the water pipe 302 in real time. When the filter device 1 is used for a period of time for regular maintenance, or when the value of the flow sensor 10 is less than a threshold, the winch 13 is driven to lift the filter device 1 to clear any blockages.

[0031] In a preferred embodiment, the filter device 1 includes two U-shaped plates 5, which abut against the two ends of the first filter plate 2 and the second filter plate 3. With this structure, the two U-shaped plates 5 clamp the first filter plate 2 and the second filter plate 3, and the two ends of the first filter plate 2 and the second filter plate 3 are respectively connected to two different U-shaped plates 5.

[0032] In the preferred embodiment, vertical sliding grooves are provided on both sides of the channel 14, and multiple guide wheels 9 are provided on the U-shaped plate 5. The guide wheels 9 abut against the vertical sliding grooves, and both sides of the U-shaped plate 5 abut against the vertical sliding grooves. With this structure, when the entire device is working, the winch 13 is driven to rewind, so that the filter device 1 slides along the vertical sliding grooves of the channel 14 to the bottom of the channel 14. A flow sensor 10 is installed on the water pipe 302 on the second filter plate 3. The filter aperture of the first filter plate 2 is larger than that of the second filter plate 3. The first filter plate 2 is mainly used to intercept larger floating debris, and the second filter plate 3 further filters fine particles such as silt. The two filter screens form a graded filtration structure, which improves the filtration effect and ensures that the water entering the subsequent part of the channel is relatively clean.

[0033] In a preferred embodiment, the unblocking plate 4 includes a grid 401 with multiple unblocking posts 402. Two threaded holes 403 are located at both ends of the grid 401, and these threaded holes 403 are connected to a screw 7. With this structure, the grid 401 has multiple unblocking posts 402. One unblocking post 402 on one side of the grid 401 is used to unblock the first filter plate 2, and the other unblocking post 402 on the other side of the grid 401 is used to unblock the second filter plate 3.

[0034] In a preferred embodiment, the pusher frame 6 includes a U-shaped frame 601 with third through holes 602 at both ends. A screw 7 passes through the third through hole 602, and also passes through the first through hole 201 and the second through hole 301. With this structure, rotating the second nut 15 away from the second filter plate 3 pulls the two pushers 6, causing the unclogging plate 4 to move relative to the first filter plate 2, allowing the unclogging column 402 to pass through the filter holes on the first filter plate 2. After the first filter plate 2 is cleaned, rotating the nut 8 away from the first filter plate 2 pushes the pusher frame 6, causing the unclogging column 402 to pass through the filter holes on the second filter plate 3. After the first filter plate 2 is cleaned, moving the pusher frame 6 resets the unclogging plate 4, and rotating the nut 8 and the second nut 15 resets the unclogging plate 4, thus fixing it in place.

[0035] In the preferred embodiment, the push frame 6 is provided with two nuts 8, which are connected to the screw 7, and the other end of the nut 8 is provided with a second nut 15.

[0036] In a preferred embodiment, a support 12 is provided at the top of the channel 14, and a winch 13 is mounted on the support 12. The winch 13 is connected to the filter device 1 via a steel cable, and an ultrasonic detector 11 is mounted on the filter device 1. With this structure,

[0037] The filter device 1 is equipped with an alarm device connected to the ultrasonic detector 11 and the flow sensor 10. When the ultrasonic detector 11 detects that the thickness of the sediment on the two filter plates exceeds a certain level, indicating that the filter plates may be clogged, and at the same time the flow sensor 10 detects that the water flow is too low, the alarm device generates a warning signal when both conditions are met. The warning signal is an audible and visual alarm. The flow sensor 10 monitors the water flow through the water pipe 302 in real time.

[0038] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
