Detailed Implementation
[0053] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0054] This utility model provides an improved online monitoring and early warning device for reservoir water quality. The technical solution of this utility model is as follows:
[0055] like Figures 1-6 As shown, a reservoir water quality online monitoring and early warning device includes:
[0056] The plate body 1 has a support 3 on its top and a winding assembly fixed on the side wall of the support 3.
[0057] Cable 9, cable 9 and winding assembly are connected;
[0058] Sampling tube 11 is fixed to the bottom end of cable 9, and a counterweight 12 is fixed to the bottom of sampling tube 11.
[0059] Box 4 is fixed to the top of bracket 3, and an air pump is installed inside box 4;
[0060] The first hose 5 is connected to the output end of the air pump, and the first hose 5 is connected to the sampling tube 11.
[0061] The first solenoid valve 14 is disposed through the top of the sampling tube 11;
[0062] Two detection components are fixed to the two side walls of plate 1;
[0063] The detection components include:
[0064] Recycling bin 31 is fixed to the top of plate 1;
[0065] Multiple detection units, all of which are fixed to plate 1;
[0066] Connecting seat 15, connecting seat 15 is connected to multiple detection units;
[0067] The second hose 13 is connected to the connecting seat 15, and the second hose 13 is disposed through the bottom of the sampling tube 11.
[0068] The height of the sampling tube 11 is adjusted by the winding assembly and the counterweight 12 to achieve water sample collection at different depths. After the sampling tube 11 reaches the appropriate depth, the first solenoid valve 14 is turned on. After the first solenoid valve 14 is turned on, water enters the sampling tube 11 through the first solenoid valve 14 to achieve water sample collection.
[0069] Furthermore, the detection unit includes:
[0070] Fixing plate 16, fixing plate 16 is fixed to the side wall of plate body 1;
[0071] The detection tank 17 and the reagent tank 18 are both fixed to the fixing plate 16;
[0072] The drug delivery tube 24 penetrates the bottom of the medicine tank 18;
[0073] Liquid supply assembly is installed inside the detection tank 17 and is connected to the drug delivery pipe 24;
[0074] The connecting pipe 20 is designed to pass through the top of the detection tank 17, and the connecting pipe 20 is connected to the connecting seat 15;
[0075] The second solenoid valve 26 is installed through the top of the detection tank 17. One end of the second solenoid valve 26 is fixed with a pipe body 19, and the pipe body 19 is connected to the recovery box 31.
[0076] The third hose 32 is connected to the other end of the second solenoid valve 26. A counterweight ring is provided at the bottom of the third hose 32, and multiple protrusions are provided at the bottom of the counterweight ring.
[0077] Furthermore, the liquid supply assembly includes:
[0078] Fixing bracket 23 is fixed inside the testing tank 17;
[0079] Sleeve 22 is fixed to the top of the fixing bracket 23;
[0080] The second piston 28 is slidably disposed inside the sleeve 22;
[0081] The second check valve 29 is disposed through the top of the second piston 28;
[0082] Hollow tube 27 is disposed on the top of the second one-way valve 29 and penetrates the top of the sliding sleeve 22;
[0083] Spring 30 is fixed on the inner wall of sleeve 22, and spring 30 is also fixed to the second piston 28.
[0084] Furthermore, it also includes:
[0085] The first one-way valve 25 is disposed through the side wall of the sleeve 22 and is connected to the drug delivery tube 24.
[0086] Furthermore, it also includes:
[0087] The first piston 21 is slidably disposed inside the detection tank 17, and the hollow tube 27 passes through the top of the first piston 21.
[0088] The counterweight ring ensures that the bottom of the third hose 32 is always at a suitable distance from the first piston 21. Even if the counterweight ring comes into contact with the first piston 21, the liquid in the detection tank 17 can still be output through the third hose 32, the second solenoid valve 26 and the tube body 19 under the action of the protrusion.
[0089] Furthermore, the winding component includes:
[0090] Motor 6 is fixed to the side wall of bracket 3;
[0091] The take-up reel 7 is rotatably connected to the bracket 3, and the output end of the motor 6 is fixed to the take-up reel 7;
[0092] Angle sensor 8 is fixed on the side wall of bracket 3, and the input end of angle sensor 8 is fixed to the take-up reel 7.
[0093] When the switch of motor 6 is turned on, motor 6 drives the winding reel 7 to rotate, thereby releasing the cable 9 on the winding reel 7. Under the gravity of the counterweight 12, the sampling tube 11 is lowered. During this process, the rotation angle of the winding reel 7 is recorded by the angle sensor 8, thereby recording the descent distance of the sampling tube 11, so as to record the sampling depth of the water sample.
[0094] Furthermore, an annular airbag 2 is provided at the bottom of the plate 1, and two guide wheels 10 are provided at the top of the plate 1, with the cable 9 passing between the two guide wheels 10.
[0095] Specifically, the working principle is as follows: Before use, various reagents for testing are first placed into each reagent tank 18. Then, a certain amount of gas is injected into the reagent tank 18 so that part of the reagent in the reagent tank 18 enters the sleeve 22 through the drug delivery pipe 24 and the first one-way valve 25 and is located in the space below the second piston 28. Then, the device is placed on the water surface, and the device floats on the water surface due to the buoyancy of the annular airbag 2.
[0096] When conducting water quality monitoring, the switch of motor 6 is turned on. When motor 6 is working, it drives the winding reel 7 to rotate, thereby releasing the cable 9 on the winding reel 7. Under the gravity of the counterweight 12, the sampling tube 11 is lowered. During this process, the rotation angle of the winding reel 7 is recorded by the angle sensor 8, thereby recording the descent distance of the sampling tube 11, so as to record the sampling depth of the water sample.
[0097] After the sampling tube 11 descends to the sampling depth, the switch of the first solenoid valve 14 is turned on. After the first solenoid valve 14 is turned on, water enters the sampling tube 11 through the first solenoid valve 14 to collect water samples.
[0098] After sampling, the first solenoid valve 14 is closed, and the air pump is switched on. When the air pump is working, gas is continuously injected into the sampling tube 11 through the first hose 5, so that the water sample in the sampling tube 11 enters the connecting seat 15 through the second hose 13, and then enters each detection tank 17 through the connecting pipes 20 on the connecting seat 15. When the water sample enters the detection tank 17, it pushes the first piston 21 to move downward, and then pushes the second piston 28 down through the hollow tube 27 and the second one-way valve 29. This allows the reagent in the sleeve 22 below the second piston 28 to be injected into the area above the first piston 21 through the second one-way valve 29 and the hollow tube 27 to mix with the water sample. At the same time, the spring 30 is compressed. After the water sample and reagent in the detection tank 17 are mixed and react for a period of time, the detection results can be recorded by the sensor set in the sampling tube 11 and sent to the monitoring center through the data network.
[0099] After the test is completed, the air pump is turned on again, so that the water in the sampling tube 11 is continuously injected into the test tank 17. During this process, the second solenoid valve 26 is turned on so that the water in the test tank 17 can enter the recovery box 31 through the third hose 32, the second solenoid valve 26 and the tube body 19 for storage, so as to prevent the test reagent from contaminating the reservoir water source.
[0100] After the second solenoid valve 26 is turned on, the water in the detection tank 17 can be output, and under the action of the spring 30, the second piston 28 is pushed to rise and reset. During the reset process of the second piston 28, the medicine in the medicine tank 18 enters the space below the second piston 28 in the sleeve 22 through the medicine delivery pipe 24 and the first one-way valve 25, in preparation for the next detection work.
