[0021] Compared with the traditional water quality online detection equipment, the detection probe 5 is moved between the detection pipe 1 and the flushing pipe 6 through the moving frame 4 including the plugging disc one 401 and the plugging disc two 402, so that the flushing of a plurality of different detection probes 5 is facilitated, the residual of pollutants on the detection probe 5 is reduced, and the detection accuracy is improved.

[0022] Please refer to Figure 4 、 Figure 8 and Figure 13 , the radial power mechanism includes a plurality of sliding blocks 16 rotationally connected with the plug-in disc 405, the side wall of the sliding block 16 is fixedly connected with a sliding column 17, the sliding column 17 is slidingly connected with a groove cylinder 18, the groove cylinder 18 is rotationally sleeved outside the detection pipe 1, the inner wall of the groove cylinder 18 is fixedly connected with a gear ring 19, the gear ring 19 is engaged with a driving gear one 20, the output shaft of a first motor 21 is fixedly connected with the driving gear one 20, and the first motor 21 is fixedly connected with the outer wall of the detection pipe 1; the outer wall of the side of the groove cylinder 18 towards the sliding block 16 is provided with a guide groove 1801, when the groove cylinder 18 rotates, the guide groove 1801 pushes the sliding column 17 and the sliding block 16 to move radially, and the sliding block 16 drives the moving frame 4 to move radially.

[0023] Specifically, the first motor 21 drives the gear ring 19 to rotate through the driving gear one 20, the gear ring 19 drives the groove cylinder 18 to rotate, the guide groove 1801 pushes the sliding column 17 and the sliding block 16 to move radially, the sliding block 16 drives the moving frame 4 to move radially, the moving frame 4 drives the detection probe 5 to move radially, and then the detection end of the detection probe 5 moves to the communication position of the flushing pipe 6 and the radial pipe 3.

[0024] Please refer to Figure 10 , the guide groove 1801 includes an arc-shaped groove one 1802 close to the detection pipe 1 and an arc-shaped groove two 1803 located outside the arc-shaped groove one 1802, the arc-shaped groove two 1803 and the arc-shaped groove one 1802 are concentrically arranged and communicate with each other.

[0025] Specifically, when the sliding column 17 slides in the arc-shaped groove one 1802, the detection end of the detection probe 5 of the detection assembly 2 corresponding to the sliding column 17 is located in the detection pipe 1, when the sliding column 17 slides into the arc-shaped groove two 1803, the detection end of the detection probe 5 corresponding to the sliding column 17 is located in the flushing pipe 6; with the circumferential motion of the groove cylinder 18, the detection end of the detection probe 5 of each detection assembly 2 independently enters the flushing pipe 6, and the independent flushing of each detection probe 5 is realized.

[0026] Please refer to Figure 8 and Figure 14 The rotating mechanism for driving the rotation of the moving frame 4 is connected with the plug-in disc 405, and comprises a plurality of transmission shafts 22 arranged opposite to the plug-in disc 405. The upper part of each transmission shaft 22 is rotatably connected with a fixed cylinder 28 fixedly connected with the detection tube 1. The upper end of each transmission shaft 22 is fixedly connected with a driven gear 23. The driven gear 23 is engaged with a toothed cylinder 24 rotatably connected with the fixed cylinder 28. The end of the toothed cylinder 24 away from the driven gear 23 is engaged with a driving gear two 25. The output shaft of a second motor 26 is fixedly connected with the driving gear two 25. The second motor 26 is fixedly connected with the side wall of the fixed cylinder 28.

[0027] Specifically, when the sliding column 17 moves into the arc-shaped groove two 1803, the transmission shaft 22 is inserted into the plug-in disc 405. The second motor 26 drives the driving gear two 25 to rotate. The driving gear two 25 drives the driven gear 23 to rotate through the toothed cylinder 24. The driven gear 23 drives the plug-in disc 405 to rotate through the transmission shaft 22, thereby driving the moving frame 4 and the detection probe 5 thereon to rotate. When the detection probe 5 is flushed, the moving frame 4 drives the detection probe 5 to rotate, so that the water flow fully contacts each face of the detection end of the detection probe 5. The centrifugal force during the rotation of the detection probe 5 accelerates the separation of the pollutants from the detection probe 5, thereby improving the flushing and cleaning effect of the pollutants.

[0028] Please refer to Figure 4 and Figure 6 The outer end of the radial tube 3 away from the detection tube 1 is rotatably connected with a rotating disc 301. The detection probe 5 and the long rod 404 are both movably penetrated through the rotating disc 301.

[0029] Specifically, the rotating disc 301 improves the stability of the moving frame 4 during the radial movement and rotation of the moving frame 4.

[0030] Please refer to Figure 8 and Figure 9 The transmission shaft 22 comprises a prismatic shaft 2201 clamped with the plug-in disc 405. The outer side of the prismatic shaft 2201 is slidably sleeved with a prismatic cylinder 2202. The prismatic cylinder 2202 is internally provided with a spring one 2203 abutting against the end of the prismatic shaft 2201.

[0031] Specifically, the prismatic shaft 2201 is kept in the state of extending to the outside of the prismatic cylinder 2202 under the action of the spring one 2203, so as to facilitate the insertion of the prismatic shaft 2201 into the plug-in disc 405.

[0032] Please refer to Figure 5 and Figure 9The sliding block 16 is a square block with an isosceles trapezoidal cross section, the prism shaft 2201 has a pointed end close to one end of the plug-in disc 405, and the pointed end surface is fixedly connected with a plurality of plug-in pieces 2204 uniformly distributed in a circle, and the plug-in disc 405 is provided with a plug-in cavity 406 matched with the pointed end of the prism shaft 2201.

[0033] Specifically, in the process that the sliding column 17 slides from the arc-shaped slot one 1802 to the arc-shaped slot two 1803, the prism shaft 2201 is extended outward under the action of the spring one 2203, slides along the surface of the sliding block 16, and then is inserted into the plug-in cavity 406 of the plug-in disc 405, so as to realize the clamping of the prism shaft 2201 and the plug-in disc 405. With the rotation of the groove cylinder 18, the clamping and disengagement of the plug-in disc 405 and each detection assembly 2 are realized.

[0034] The second embodiment is as follows: Figure 4 , Figure 6 , Figure 7 , Figure 10 , Figure 15 The pure water quality on-line detection equipment is shown, and on the basis of the first embodiment, the radial pipe 3 is fixedly connected with a calibration pipe 9 away from one end of the flushing pipe 6, the right end of the calibration pipe 9 is communicated with the water injection cylinder 12, and the two communication positions are fixedly connected with the electromagnetic valve two 10, the left end of the calibration pipe 9 is fixedly communicated with the water discharge cylinder 13, and the two communication positions are fixedly communicated with the one-way valve two 11, and the electromagnetic valve one 7, the electromagnetic valve two 10, the detection probe 5, the first motor 21 and the second motor 26 are electrically connected with the same controller.

[0035] Specifically, after the detection of the detection probe 5 ends in the flushing pipe 6, the detection probe 5 is moved into the calibration pipe 9 through the radial power mechanism, then the standard solution is injected into the calibration pipe 9 through the external water supply mechanism, and the standard solution injected into the calibration pipe 9 is detected by the detection probe 5. When the difference between the detection value and the actual value of the standard solution (the pure water with known parameters) is greater than the set difference threshold value, the controller issues an alarm to remind the operator to repair. It should be noted that the controller is connected with the computer in the remote control room, and the alarm is prior art, which will not be described herein. In addition, it should be particularly noted that the actual value of the standard solution is known, and the reason why the detection value detected by the detection probe 5 is greatly different from the actual value is multifaceted, including but not limited to damage of the detection probe 5 or failure of the flushing mode to clean the stubborn residual pollutants on the surface of the detection probe 5, so manual inspection is required. In addition, the detection of the detection probe 5 in the calibration pipe 9 is to exclude the possibility that residual pollutants in the flushing pipe 6 affect the detection result.

[0036] Compared with the traditional water quality on-line detection device, the calibration pipe 9 arranged outside the flushing pipe 6 is arranged, the detection probe 5 after flushing is calibrated and detected, when the real-time detection value and the actual value of the standard solution are greatly different, an alarm is given, the operator is reminded to timely repair, and the detection accuracy of the on-line detector and the timeliness of maintenance are improved.

[0037] Please refer to Figure 10 The guide groove 1801 further comprises an arc-shaped groove three 1804 concentrically arranged outside the arc-shaped groove two 1803, and the arc-shaped groove three 1804 is in communication with the arc-shaped groove two 1803 and the arc-shaped groove one 1802 at both ends.

[0038] Specifically, when the sliding column 17 moves into the arc-shaped groove three 1804, the detection end of the detection probe 5 of the detection assembly 2 corresponding to the sliding column 17 moves into the calibration pipe 9.

[0039] Please refer to Figure 4 and Figure 6 The end of the radial pipe 3 in the detection pipe 1 is sleeved with an elastic cover 27, the elastic cover 27 comprises an open cover 2701 sleeved outside the inner end of the radial pipe 3, the open cover 2701 is in a cylindrical shape with an open outer end, and an arc-shaped through groove 2702 is formed in the circumferential side wall of the open cover 2701, the inner side of the open cover 2701 is in abutment with a spring two 2703, and the inner end of the spring two 2703 is in abutment with a protruding ring 302 fixedly connected with the outer wall of the radial pipe 3.

[0040] Specifically, in the process that the detection probe 5 extends into the detection pipe 1, the sealing disc one 401 extrudes the open cover 2701, so that the spring two 2703 is compressed, until the arc-shaped through groove 2702 on the open cover 2701 is in communication with the inner cavity of the detection pipe 1, and the detection water sample flows through the detection end of the detection probe 5 after passing through the arc-shaped through groove 2702; when flushing and calibration detection are performed, the inner end of the radial pipe 3 is sealed by the open cover 2701 under the action of the spring two 2703, so that the detection water sample is prevented from entering the radial pipe 3 and polluting the flushing pipe 6.

[0041] In combination with the current actual demand, the above-mentioned embodiments adopted by the present application are not limited to this, various changes made within the knowledge range of those skilled in the art without departing from the concept of the present application still fall within the protection range of the present application.
