[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting a first judgment component, uses a first pressure sensor and a second pressure sensor to detect the pressure change before and after the filter plate. As the filter plate is used for longer, impurities will gradually accumulate on the filter plate, resulting in an increase in the pressure difference before and after the filter plate. By monitoring this pressure difference in real time, the degree of clogging of the filter plate can be accurately determined, providing a key basis for whether the filter plate needs to be replaced.

When the filter plate is damaged or its filtration performance declines, the content of impurities and harmful substances in the water will change. The water quality sensor can monitor these changes in real time. Compared with relying solely on pressure difference for judgment, it adds another dimension to the judgment, making the judgment on whether the filter plate needs to be replaced more accurate and comprehensive, and reducing misjudgments.

[0017] 3. This utility model, by setting up an alarm component, when the controller receives an abnormal signal from the first pressure sensor, the second pressure sensor, or the water quality sensor, and determines that the filter plate needs to be replaced, the controller sends an electrical signal to the indicator light. After receiving the signal, the indicator light lights up, using a conspicuous light signal to remind the staff that the filter plate may need to be replaced. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4 As shown, this utility model provides a filter pipe for water conservancy projects, including a main filter box 1, a connecting pipe 2, a filter plate 3, a slot 4, a cover plate 5, and a mounting block 6. The connecting pipe 2 connects the left and right sides of the main filter box 1. The filter plate 3 is disposed inside the main filter box. The cover plate 5 is fixedly installed on the top of the main filter box 1. The slot 4 is opened on the top of the cover plate 5. The mounting block 6 is fixedly installed on the top of the cover plate 5. The bottom of the mounting block 6 is fixedly installed to the top of the filter plate 3 through the slot 4. A first judgment component 7 is provided on the left and right sides of the bottom front of the main filter box 1. The first judgment component 7 includes a first mounting hole 71, a second... A mounting hole 71 is provided on the left and right sides of the bottom front of the main filter box 1. A first pressure sensor 72 is installed inside the first mounting hole 71 on the left side, and a second pressure sensor 73 is installed inside the first mounting hole 71 on the right side. The detection ends of the first pressure sensor 72 and the second pressure sensor 73 are located inside the main filter box 1. A controller 74 is provided on the back of the main filter box 1. The controller 74 is electrically connected to the first pressure sensor 72 and the second pressure sensor 73 through wires. A second judgment component 8 is provided at the bottom right side of the main filter box 1. A warning component 9 is fixedly installed on the front of the main filter box 1.

[0025] refer to Figure 3The second judgment component 8 includes a second mounting hole 81, which is located at the bottom right side of the main filter box 1. A water quality sensor 82 is installed inside the second mounting hole 81. The detection end of the water quality sensor 82 is located inside the main filter box 1. The water quality sensor 82 is electrically connected to the controller 74 through a wire.

[0026] As a technical optimization of this utility model, by setting a second judgment component 8 and adding a water quality sensor 82, the filtration effect of the filter plate 3 can be directly reflected from the perspective of water quality. When the filter plate 3 is damaged or its filtration performance declines, the content of impurities and harmful substances in the water will change. The water quality sensor 82 can monitor these changes in real time. Compared with judging solely by pressure difference, this adds another judgment dimension, making the judgment on whether the filter plate 3 needs to be replaced more accurate and comprehensive, and reducing misjudgments.

[0027] refer to Figure 1 The warning component 9 includes a mounting plate 91, which is fixedly installed on the top of the front of the main filter box 1. Indicator lights 92 are fixedly installed on the left and right sides of the top of the mounting plate 91. The indicator lights 92 are electrically connected to the controller 74 through wires.

[0028] As a technical optimization of this utility model, by setting an alarm component 9, when the controller 74 receives an abnormal signal from the first pressure sensor 72, the second pressure sensor 73 or the water quality sensor 82 and determines that the filter plate 3 needs to be replaced, the controller 74 sends an electrical signal to the indicator light 92. After receiving the signal, the indicator light 92 lights up, using a conspicuous light signal to remind the staff that the filter plate 3 may need to be replaced.

[0029] refer to Figure 4 The second judgment component 8 includes a second mounting hole 81, which is located at the bottom right side of the main filter box 1. A water quality sensor 82 is installed inside the second mounting hole 81. The detection end of the water quality sensor 82 is located inside the main filter box 1. The water quality sensor 82 is electrically connected to the controller 74 via a wire. A fixing block 14 is fixedly installed on the surface of the first pressure sensor 72, the second pressure sensor 73, and the water quality sensor 82. The side of the fixing block 14 away from the first pressure sensor 72, the second pressure sensor 73, and the water quality sensor 82 is fixedly connected to the main filter box 1.

[0030] As a technical optimization of this utility model, a fixing block 14 is set to stabilize the first pressure sensor 72, the second pressure sensor 73 and the water quality sensor 82, so as to prevent the sensors from shifting or shaking under the influence of water flow impact, pipeline vibration and other conditions, and to ensure that the detection data is stable and reliable.

[0031] refer to Figure 4A sealing ring 10 is provided inside the first mounting hole 71 and the second mounting hole 81. The sealing ring 10 is sleeved on the surface of the first pressure sensor 72, the second pressure sensor 73 and the water quality sensor 82.

[0032] As a technical optimization of this utility model, a sealing ring 10 is set and fitted on the surface of the sensor, filling the gap between the sensor and the mounting hole. Under the pressure of water, the sealing ring 10 undergoes elastic deformation, tightly adhering to the sensor and the inner wall of the mounting hole, forming a sealing barrier to prevent water leakage. This ensures that the water in the main filter box 1 can only flow along the designed path, guaranteeing that the normal working environment of the sensor is not affected by water leakage.

[0033] refer to Figure 2 A control box 11 is fixedly installed on the back of the main filter box 1, and a controller 74 is fixedly installed inside the controller 74.

[0034] As a technical optimization of this utility model, by setting up a control box 11, the control box 11 provides protection for the controller 74, preventing the controller 74 from being directly exposed to the external environment. The control box 11 can block harmful substances from the outside, protect the controller 74 to operate stably, and improve the reliability and stability of the entire judgment system.

[0035] refer to Figure 2 Buzzers 12 are fixedly installed on the top and bottom of the left side of the control box 11. The buzzers 12 are electrically connected to the controller 74 through wires.

[0036] As a technical optimization of this utility model, a buzzer 12 is set up, which works in conjunction with an indicator light 92 to supplement the light signal with a sound signal. In a noisy water conservancy project site, a loud sound is emitted, which can alert the staff by hearing and ensure that the staff can receive the warning information that the filter plate 3 needs to be replaced in a timely manner even in a complex environment.

[0037] refer to Figure 1 The front of the main filter box 1 is inlaid with an observation window 13 through a through groove. The observation window 13 is made of transparent acrylic.

[0038] As a technical optimization of this utility model, by setting an observation window 13, it is convenient for staff to directly observe the status of the filter plate 3. During the use of the filter plate 3, the observation window 13 can be used to check whether the filter plate 3 is damaged, clogged, or otherwise visually affected.

[0039] The working principle and usage process of this utility model are as follows: During use, the main filter box 1 is installed in a suitable location in the water conservancy project, ensuring a stable connection with upstream and downstream pipelines to guarantee smooth water flow through the main filter box 1. The connecting pipe 2 is accurately connected to the left and right sides of the main filter box 1 to facilitate water inflow and outflow. The filter plate 3 is fixed to the cover plate 5 via the slot 4 and mounting block 6. The cover plate 5 is then installed on the top of the main filter box 1, ensuring the filter plate 3 is securely installed and well-sealed to prevent water bypass. The filter plate 3 is located on the left and right sides of the bottom front of the main filter box 1. A first pressure sensor 72 and a second pressure sensor 73 are installed in mounting hole 71, respectively. A water quality sensor 82 is installed in the second mounting hole 81 at the bottom right side of the main filter box 1. During installation, the sensor is secured with fixing block 14, and sealing ring 10 is used to ensure stable installation and prevent leakage. The first pressure sensor 72, the second pressure sensor 73, and the water quality sensor 82 are connected to the controller 74 using wires. The indicator light 92, buzzer 12, and other warning components 9 are also connected to the controller 74 to ensure correct electrical connections. The system is stable. Water flows into the main filter box 1 through the connecting pipe 2. When the water flows through the filter plate 3, the filter plate 3 intercepts impurities in the water, achieving water filtration. The first pressure sensor 72 and the second pressure sensor 73 monitor the pressure before and after the filter plate 3 in real time, and the water quality sensor 82 monitors the water quality after filtration in real time. These sensors convert the detected pressure and water quality data into electrical signals and transmit them to the controller 74. After receiving the signals from the sensors, the controller 74 compares the pressure difference data with the preset pressure difference threshold and the water quality data with the preset water quality standard. When the impurities on the filter plate 3 accumulate more, the resistance of the water flow through the filter plate 3 increases, the pressure before the filter plate 3 will rise, and the pressure after the filter plate 3 will decrease, resulting in an increase in the pressure difference. When the pressure difference exceeds the preset threshold of the controller 74, it indicates that the filter plate 3 is seriously blocked. The controller 74 determines that the filter plate 3 may need to be replaced. When the controller 74 determines that the filter plate 3 needs to be replaced, it will send a signal to the indicator light 92 and the buzzer 12. The indicator light 92 lights up, and the buzzer 12 sounds, reminding the staff in a way that combines light and sound.

[0040] In summary, this water conservancy engineering filter pipe, by setting a first judgment component 7, uses a first pressure sensor 72 and a second pressure sensor 73 to detect pressure changes before and after the filter plate 3. As the filter plate 3 is used for longer periods, impurities will gradually accumulate on the filter plate 3, causing the pressure difference before and after the filter plate 3 to increase. By monitoring this pressure difference in real time, the degree of blockage of the filter plate 3 can be accurately determined, providing a key basis for whether the filter plate 3 needs to be replaced, and solving the problem in the prior art that the actual filtration status of the filter plate cannot be known in a timely manner.
