Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to an on-line water pollution source detection device. Background Technique

[0002] With the development of social economy, scientific progress and the improvement of people's living standards, people's requirements for the water quality of domestic drinking water are constantly increasing, and the drinking water quality standards are also constantly developing and improving accordingly. Therefore, it is necessary to detect water to ensure its drinking safety.

[0003] The existing on-line water pollution source detection device can refer to the utility model patent with the Chinese patent publication number of CN220357051U. It discloses an on-line water pollution source detection device, including a support block. An fixing plate is arranged on the support block. The fixing plate is connected with a baffle. A water quality detector body is installed on the fixing plate below the baffle. The water quality detector body is electrically connected with a water quality detection probe; a protection mechanism is arranged on the fixing plate. The protection mechanism includes a protection frame and a lead screw. The lead screw is installed at the top end of the fixing plate. The protection frame is rotationally installed at the front end of the fixing plate through the lead screw. Fixed springs are arranged on both sides of the protection frame.

[0004] Although this device is convenient for isolation protection, is beneficial to increasing the service life and is convenient for increasing the detection accuracy; however, the frame plate in its protection mechanism is a rotating plate rotatably connected with the support block, lacking a fixing mechanism. Therefore, in the case of large water waves, it is easy to wash open the frame plate. At the same time, its bottom is hollow without a protection structure, and water can pass through here to affect the water quality detector. Summary of the Utility Model

A water quality detector is provided on the inner wall of the protection box 301; a positioning groove 303 is formed on one side of the protection box 301 close to the protection cover 302, a circular groove 304 is formed on the side of the protection cover 302 away from the protection box 301, and a positioning pin 305 is clamped on the inner wall of the positioning groove 303;

[0032] One side of the positioning pin 305 away from the circular groove 304 is fixedly connected to the protection cover 302. A spring 306 providing elastic force is fixedly assembled on the inner wall of the circular groove 304, and a pressing block 310 is fixedly assembled at one end of the spring 306 away from the circular groove 304;

[0033] One side of the pressing block 310 close to the spring 306 is fixedly assembled with a moving shaft 307. An annular groove 308 is formed on the outer wall of the moving shaft 307, a ball 309 abuts against the outer wall of the moving shaft 307, and the ball 309 is clamped with the inner wall of the positioning groove 303;

[0034] A groove 311 is formed on one side of the protection box 301 close to the protection cover 302, and a sealing ring 312 is clamped on the inner wall of the groove 311. One side of the sealing ring 312 away from the protection box 301 is fixedly connected to the protection cover 302. By providing the groove 311 and the sealing ring 312, it is beneficial to improve the sealing performance at the connection between the protection box 301 and the protection cover 302.

[0035] As Figure 1 Figure 2 and Figure 3 shown, the fixed frame 1 includes a motor 201 installed on the top of the fixed frame 1. The end of the output shaft of the motor 201 is fixedly assembled with a lead screw 202. A moving ring 203 is threadedly connected to the outer wall of the lead screw 202, and a positioning plate 204 is fixedly assembled on the outer wall of the moving ring 203;

[0036] A water level sensor 205 is fixedly assembled on the top of the positioning plate 204. The water level sensor 205 is electrically connected to the motor 201. Water quality detection probes 206 are fixedly assembled on both sides of the positioning plate 204. Scale lines 207 are provided on the outer wall of the fixed frame 1;

[0037] The water level is monitored by the water level sensor 205. When the water level changes, the water level sensor 205 sends a signal to the motor 201, and the motor 201 drives the lead screw 202 to rotate, thereby driving the moving ring 203 and the positioning plate 204 to move longitudinally, so that the positioning plate 204 and the water quality detection probes 206 can change in time following the change of the water level, which is beneficial to improving the adaptability of the device and the accuracy of the detection effect of the device.

[0038] As Figure 1As shown, a fixing plate 4 is fixedly assembled at the bottom of the fixing frame 1, and a fixing hole 5 is formed at the top of the fixing plate 4. By providing the fixing plate 4 and the fixing hole 5, it is beneficial to facilitate the fixing of the device through the fixing hole 5 and improve the stability of the device during use.

[0039] As Figure 2 and Figure 4 shown, an observation port 313 is formed on the outer wall of the protective cover 302, and an observation window 314 is fixedly assembled on the inner wall of the observation port 313.

By limiting the number and positions of the springs 306, moving shafts 307 and pressing blocks 310, it is beneficial to improve the firmness when the protective box 301 is connected to the protective cover 302.

[0041] During work, by inserting the positioning pin 305 on the protective cover 302 into the positioning groove 303, and then pressing the pressing block 310, the ball 309 is driven to move during the movement of the moving shaft 307. At this time, the ball 309 is located inside the annular groove 308. When moving to the clamping position in the circular groove 304, the ball 309 rolls towards the clamping position, and then the pressing block 310 is released. The spring 306 pushes the moving shaft 307 towards the position of the pressing block 310. At this time, the moving shaft 307 presses the ball 309 at the clamping position, and finally the connection and fixation of the protective cover 302 and the protective box 301 are completed. Repeating the above steps can remove the protective cover 302;

[0042] The water level is monitored by the water level sensor 205. When the water level changes, the water level sensor 205 sends a signal to the motor 201, and the motor 201 drives the lead screw 202 to rotate, thereby driving the moving ring 203 and the positioning plate 204 to move longitudinally, so that the positioning plate 204 and the water quality detection probe 206 can change in time following the change of the water level, which is beneficial to improve the adaptability of the device and the accuracy of the detection effect of the device.
