Description

Technical Field

[0001] The present invention relates to the technical field of water quality detection, and in particular to a water quality detection device for a water supply pipeline. Background Art

[0002] In the process of piped water supply, it is necessary to detect the water quality therein, such as the pH value, turbidity, etc. The current detection method is to insert the detector directly into the water supply pipe and perform corresponding detection. The overall operation is simple, but in the actual detection process, the flowing water and impurities in the water come into contact with the detector, which will cause the detector to move relative to the pipe and cause great damage to the detector, thereby reducing the service life of the detector. In addition, in the detection process, impurities in the water are mostly accumulated on the lower side of the pipe, and the detection water is not in a balanced state, resulting in large errors in the detection of water turbidity and inaccurate detection results. In the actual detection process, the detector is in the detection water for a long time. When impurities stick to the detector, the subsequent detection results of the detector will be less accurate. In addition, the traditional detection device can only complete the water quality detection operation and cannot detect whether the pipe is leaking. Therefore, a water quality detection device for water supply pipes is provided. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a water quality detection device for water supply pipelines.

[0004] The present invention adopts the following technical solutions: A water quality detection device for water supply pipelines comprises a mounting pipe, a fixed pipe is fixedly sleeved on the outer side of the mounting pipe, a fixed plate is fixedly connected to the upper side of the fixed pipe via a connecting rod, a control assembly is installed on the upper side of the fixed plate, a hydraulic rod is fixedly connected to the lower side of the fixed plate, a mounting ring is slidably sleeved on the outer side of the hydraulic rod, a plurality of detectors are fixedly installed on the lower side of the mounting ring, a plurality of moving rods are fixedly connected to the lower side of the hydraulic rod, a same piston plate is fixedly connected to the lower side of the plurality of moving rods, the piston plate is slidably connected to the fixed pipe, and a plurality of discharge pipes are opened on the side wall of the fixed pipe.

[0005] Preferably, a wiping assembly for wiping the side wall of the detector is installed on the upper side of the piston plate, and the wiping assembly includes a slide plate fixedly installed on the lower side of the detector, and a sleeve is slidably sleeved on the outer side of the slide plate. The sleeve is located on the upper side of the piston plate and fixedly connected to the piston plate. The detector is located in the sleeve and is slidably sleeved with a wiping ring, and the wiping ring is fixedly connected to the inner wall of the sleeve.

[0006] Preferably, a stirring assembly for stirring the test water is installed on the lower side of the piston plate, and the stirring assembly includes a threaded rod fixedly installed on the lower side of the piston plate, a threaded barrel is threadedly sleeved on the outer side of the threaded rod, and the threaded barrel is rotatably connected to the inner wall of the mounting tube, and multiple groups of stirring rods are circumferentially fixedly connected to the outer side of the threaded barrel.

[0007] Preferably, a detection component for detecting water capacity is installed in the hydraulic rod, and the detection component includes a cavity opened in the hydraulic rod, a pressure sensor is slidably sleeved in the cavity, a spring is fixedly connected between the pressure sensor and the side wall of the cavity, a control rod is fixedly connected to the output end of the pressure sensor, the control rod passes through the cavity and is slidably connected to the cavity, and a foam plate is fixedly connected to the lower side of the control rod.

In addition, during the testing process, the segmented testing can compare and analyze the results of the tests in different time periods, thereby improving the testing effect. In the process of testing the water quality in the pipeline, the test water inside the installation pipe can be stirred to make the tested water in a more balanced state, thereby improving the accuracy of the test results; In the process of segmented detection, the detector can be wiped by the sleeve and the wiping ring to keep the detector clean and thus maintain the detection effect of the detector. After the detector is wiped, it will not be affected by the water of the last detection, further ensuring the accuracy of the detection result. When testing the water quality, the flow rate of the test water entering the fixed pipe each time can also be tested.

DETAILED DESCRIPTION

[0014] See also Figure 1-Figure 8 , a water quality detection device for water supply pipeline, including a mounting pipe 1, such as Figure 1 , Figure 2 , Figure 3 , Figure 4The outer side of the mounting tube 1 is fixedly sleeved with a fixed tube 2, and the upper side of the fixed tube 2 is fixedly connected with a fixed plate 3 through a connecting rod 6. A control component 4 is installed on the upper side of the fixed plate 3, and a hydraulic rod 5 is fixedly connected to the lower side of the fixed plate 3. A mounting ring 7 is slidably sleeved on the outer side of the hydraulic rod 5. Multiple groups of detectors 13 are fixedly installed on the lower side of the mounting ring 7. Multiple groups of moving rods 14 are fixedly connected to the lower side of the hydraulic rod 5. The lower sides of the multiple groups of moving rods 14 are fixedly connected with the same piston plate 15. The piston plate 15 is slidably connected to the fixed tube 2. Multiple groups of discharge pipes 25 are opened on the side wall of the fixed tube 2. Multiple groups of single-way control valves 17 are fixedly connected to the lower side of the fixed tube 2 in a circumferential direction. The multiple groups of single-way control valves 17 are communicated with the discharge pipe 25. Under the action of the single-way control valve 17, when the detection water flows in the mounting tube 1, the detection water will not enter the fixed tube 2 through the discharge pipe 25. The detection water can only flow from the fixed tube 2 to the mounting tube 1 to prevent the occurrence of backflow. First, the control component 4 includes a display screen and multiple groups of buttons matching the display screen. The display screen can not only complete the switch control operation of the hydraulic rod 5, but also control the up and down movement rate of the hydraulic rod 5. Secondly, the number of detectors 13 is multiple groups, and the multiple groups of detectors 13 can detect the pH value, turbidity, etc. of water quality. When the detector 13 is located in the test water, the detection operation can be completed, and the detected data can be displayed on the display screen. The above are all existing technologies and no unnecessary details are given. When it is necessary to perform a detection operation on the pipeline water quality, the installation pipe 1 and the water supply pipe are threaded together, and the hydraulic rod 5 is started by the control component to move the hydraulic rod 5 up and down. The hydraulic rod 5 drives the piston plate 15 up and down through the moving rod 14. When the piston plate 15 is moved out of the fixed pipe 2, the installation pipe 1 and the fixed pipe 2 are in a connected state, and the test water to be detected in the installation pipe 1 enters the fixed pipe 2 (in the actual water supply system, a certain pressure will be applied to the water through the corresponding pressure pump, In this way, water can be quickly moved along the pipeline to achieve a water supply effect. Therefore, when the installation pipe 1 and the fixed pipe 2 are connected, the clean water inside the installation pipe 1 will enter the fixed pipe 2), and then when the piston plate 15 moves upward, the fixed pipe 2 and the installation pipe 1 will be disconnected again, and the fixed pipe 2 and the installation pipe 1 are not in a connected state. At this time, there will be a certain amount of test water in the fixed pipe 2. At this time, the water quality of the test water can be detected by the detector 13, and then in the process of the piston plate 15 continuing to move upward, the liquid level of the test water inside the fixed pipe 2 moves upward with the piston plate 15. When the liquid level of the test water passes the discharge pipe 25, the test water inside the fixed pipe 2 is discharged into the installation pipe 1 through the discharge pipe 25 until the piston plate 15 moves to the uppermost side, and then when the piston plate 15 moves downward again, the device as a whole repeats the above operation, thereby achieving a segmented detection operation of the water quality, and the detector 13 is less impacted by the test water, thereby ensuring the service life of the detector 13.

[0015] like Figure 5 A wiping assembly for wiping the side wall of the detector 13 is installed on the upper side of the piston plate 15. The wiping assembly includes a slide plate 24 fixedly installed on the lower side of the detector 13. The outer side of the slide plate 24 is slidably sleeved with a sleeve 16. The sleeve 16 is located on the upper side of the piston plate 15 and is fixedly connected to the piston plate 15. The detector 13 is located in the sleeve 16 and is slidably sleeved with a wiping ring 23. The wiping ring 23 is fixedly connected to the inner wall of the sleeve 16; In the process of the piston plate 15 moving up and down, the piston plate 15 drives the sleeve 16 to move up and down, and the sleeve 16 drives the wiping ring 23 to move up and down. A towel is fixedly sleeved inside the wiping ring 23. When the detector 13 detects the water quality, the piston plate 15 drives the sleeve 16 to move upward, and the sleeve 16 drives the wiping ring 23 to move upward, forming a wiping operation on the detector 13, until the sleeve 16 and the mounting ring 7 are abutted. At this time, the piston plate 15 moves to the uppermost side. In this process, under the action of the discharge pipe 25, a part of the detection water inside the fixed tube 2 is discharged. When the piston plate 15 is located at the uppermost side, the liquid level of the detection water inside the fixed tube 2 is lower than the highest point of the sleeve 16. Therefore, in the process of the piston plate 15 moving downward, the detector 13 does not contact the detection water and will not perform the detection operation until the piston plate 15 is removed from the fixed tube 2 and the detection water enters the fixed tube 2 again. At this time, the liquid level of the detection water rises again, and the detector 13 enters the detection water again to perform the detection operation again.

[0016] A stirring assembly for stirring the test water is installed at the lower side of the piston plate 15, and the stirring assembly includes a threaded rod 8 fixedly installed at the lower side of the piston plate 15, a threaded barrel 9 is threadedly sleeved on the outer side of the threaded rod 8, and the inner wall of the mounting tube 1 is rotatably connected in the threaded barrel 9, and multiple groups of stirring rods 10 are fixedly connected to the outer side of the threaded barrel 9 in a circumferential direction; During the up and down movement of the piston plate 15, the piston plate 15 drives the threaded rod 8 to move up and down. Since the threaded rod 8 and the threaded tube 9 are threadedly connected, during the up and down movement of the threaded rod 8, the threaded rod 8 drives the threaded tube 9 to rotate, and the threaded tube 9 drives the stirring rod 10 to rotate, thereby stirring the test water inside the installation tube 1, so as to keep the test water in a balanced state as much as possible, thereby improving the accuracy of the detection effect.

[0017] like Figure 8 A detection assembly for detecting water capacity is installed in the hydraulic rod 5, and the detection assembly includes a cavity 18 opened in the hydraulic rod 5, a pressure sensor 19 is slidably sleeved in the cavity 18, a spring 20 is fixedly connected between the pressure sensor 19 and the side wall of the cavity 18, a control rod 21 is fixedly connected to the output end of the pressure sensor 19, the control rod 21 penetrates the cavity 18 and is slidably connected to the cavity 18, and a foam plate 22 is fixedly connected to the lower side of the control rod 21; First, the pressure sensor 19 is a device or apparatus that can sense pressure signals and convert pressure signals into usable output electrical signals according to certain rules. Secondly, the density of the foam board 22 is low and it can float on the water surface. Secondly, in the process of the piston plate 15 moving upward, the liquid level inside the fixed pipe 2 moves upward with the piston plate 15. Before the liquid level inside the fixed pipe 2 moves to the position of the discharge pipe 25, the foam board 22 and the liquid level are offset. At this time, under the action of buoyancy, the foam board 22 is driven to move upward, and the foam board 22 drives the pressure sensor 19 to move upward. While the pressure sensor 19 compresses the spring 20, it releases an electrical signal and transmits this electrical signal to the display screen. Each time the test water is tested, the flow rate of the test water entering the fixed pipe 2 is within a certain range. If there is a leak in the pipeline, the pressure on the water in the pipeline decreases, which leads to a decrease in the volume of the test water entering the fixed pipe 2. The electrical signal emitted by the pressure sensor 19 changes significantly, thereby reminding the corresponding staff that there is a leak in the water supply pipeline and timely detection and maintenance are required.

[0018] like Figure 6 , Figure 7 A threaded ring 11 is fixedly sleeved on the outer side of the mounting ring 7, the threaded ring 11 is located in the fixed tube 2 and is threadedly connected to the fixed tube 2, a fixed ring 12 is fixedly sleeved in the fixed tube 2, the threaded ring 11 is located on the upper side of the fixed ring 12 and abuts against the fixed ring 12; During the water quality detection operation, if the detector 13 is damaged, the threaded ring 11 can be screwed out of the fixed pipe 2 and the detector 13 can be repaired.

[0019] In the present invention, the control component 4 includes a display screen and a plurality of groups of buttons matching the display screen. The display screen can not only complete the switch control operation of the hydraulic rod 5, but also control the up and down movement rate of the hydraulic rod 5. Secondly, the number of detectors 13 is multiple groups, and the multiple groups of detectors 13 can detect the pH value, turbidity, etc. of water quality. When the detector 13 is located in the test water, the detection operation can be completed, and the data obtained by the detection can be displayed on the display screen. The above are all prior arts and no unnecessary details are given. When it is necessary to detect the water quality of the pipeline, the installation pipe 1 and the water supply pipeline are threaded together, and the hydraulic rod 5 is started by the control component to move the hydraulic rod 5 up and down. The hydraulic rod 5 drives the piston plate 15 to move up and down through the moving rod 14. When the piston plate 15 is moved out of the fixed pipe 2, the installation pipe 1 and the fixed pipe 2 are in a connected state, and the test water to be tested in the installation pipe 1 enters the fixed pipe 2 (in the actual water supply system, a certain pressure will be applied to the water through the corresponding pressure pump, so that the water can move quickly along the pipeline to achieve the water supply effect. Therefore, when the installation pipe 1 and the fixed pipe 2 are connected, the clean water inside the installation pipe 1 will enter the fixed pipe 2). Then, when the piston plate 15 moves upward, the fixed pipe 2 and the installation pipe 1 will be disconnected again, and the fixed pipe 2 and the installation pipe 1 are not in a connected state. At this time, there will be a certain amount of test water in the fixed pipe 2. At this time, the water quality of the test water can be tested through the detector 13, and then the piston plate 15 continues to move upward. During the movement, the liquid level of the test water inside the fixed tube 2 moves upward with the piston plate 15. When the liquid level of the test water exceeds the discharge pipe 25, the test water inside the fixed tube 2 is discharged into the mounting tube 1 through the discharge pipe 25 until the piston plate 15 moves to the uppermost side. Then, when the piston plate 15 moves downward again, the device as a whole repeats the above operation, thereby achieving segmented detection of water quality, and the detector 13 is less impacted by the test water, thereby ensuring the service life of the detector 13. During the up and down movement of the piston plate 15, the piston plate 15 drives the sleeve 16 to move up and down, and the sleeve 16 drives the wiping ring 23 to move up and down. A towel is fixedly sleeved inside the wiping ring 23. When the detector 13 is detecting the water quality, the piston plate 1 5 drives the sleeve 16 to move upward, and the sleeve 16 drives the wiping ring 23 to move upward, forming a wiping operation on the detector 13, until the sleeve 16 and the mounting ring 7 are in contact with each other, at which time the piston plate 15 moves to the uppermost side. In this process, under the action of the discharge pipe 25, a part of the detection water inside the fixed tube 2 is discharged. When the piston plate 15 is located at the uppermost side, the liquid level of the detection water inside the fixed tube 2 is lower than the highest point of the sleeve 16. Therefore, during the downward movement of the piston plate 15, the detector 13 does not contact the detection water and does not perform the detection operation until the piston plate 15 is moved out of the fixed tube 2 and the detection water enters the fixed tube 2 again. At this time, the liquid level of the detection water rises again, and the detector 13 enters the detection water again to perform the detection operation again.During the up and down movement of the piston plate 15, the piston plate 15 drives the threaded rod 8 to move up and down. Since the threaded rod 8 and the threaded barrel 9 are threadedly connected, during the up and down movement of the threaded rod 8, the threaded rod 8 drives the threaded barrel 9 to rotate, and the threaded barrel 9 drives the stirring rod 10 to rotate, so as to stir the test water inside the installation tube 1, so as to make the test water in a balanced state as much as possible, thereby improving the accuracy of the detection effect. The pressure sensor 19 is a device or apparatus that can sense the pressure signal and convert the pressure signal into a usable output electrical signal according to a certain rule. Secondly, the density of the foam board 22 is low and it can float on the water surface. Secondly, during the upward movement of the piston plate 15, the liquid level inside the fixed tube 2 moves upward with the piston plate 15. Before the liquid level inside the fixed tube 2 moves to the position of the discharge pipe 25, the foam board 22 The foam plate 22 and the liquid surface are against each other. At this time, under the action of buoyancy, the foam plate 22 is driven to move upward, and the foam plate 22 drives the pressure sensor 19 to move upward. While the pressure sensor 19 compresses the spring 20, it releases an electrical signal and transmits this electrical signal to the display screen. Every time the test water is tested, the flow rate of the test water entering the fixed pipe 2 is within a certain range. If there is a leak in the pipeline, the pressure on the water in the pipeline becomes smaller, which leads to a decrease in the volume of the test water entering the fixed pipe 2. The electrical signal emitted by the pressure sensor 19 changes significantly, which reminds the corresponding staff that the water supply pipeline has a leak and needs to be tested and repaired in time. During the water quality testing operation, if the detector 13 is damaged, the threaded ring 11 can be unscrewed from the fixed pipe 2, and the detector 13 can be repaired.
