DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 5As shown, a cruise-type water quality detection device according to an embodiment of the present invention comprises two buoys 1, a fixing frame 2 is arranged between the two buoys 1, both sides of the fixing frame 2 are sleeved on the outside of the buoys 1 through collars, a navigation component 11 is arranged below one end of the buoy 1, the top of the navigation component 11 is fixedly connected to the outside of the collar of the fixing frame 2, a motor 23 is installed in the middle of the bottom end of the fixing frame 2, an output gear 21 is arranged in the middle of the top end of the fixing frame 2, the end of the rotating shaft of the motor 23 is fixedly connected to the bottom end of the output gear 21, a detection box 3 is arranged below the fixing frame 2, and the inner part of the detection box 3 A plurality of water quality detection sensors are installed in the part, two threaded rods 221 are fixed on the top of the detection box 3, the threaded rods 221 penetrate the interior of the fixing frame 2, gear sleeves 22 are arranged on both sides of the output gear 21, the gear sleeves 22 are meshed and connected with the output gear 21, the threaded rods 221 are threadedly connected with the gear sleeves 22, a plurality of upper support rods 4 are arranged at equal intervals below the detection box 3, a connecting column 42 is arranged at the bottom end of the detection box 3, a pressure sensor is installed at the top of the connecting column 42, the other end of the pressure sensor is fixedly connected with the bottom end of the detection box 3, and openings are opened at both ends of the detection box 3;

[0032] When testing the water quality of rivers and lakes, it is necessary to test the water quality of different waters, so it is necessary to use cruise-type water quality testing. When testing, the device is placed in the water. At this time, the float 1 floats on the water surface, the navigation component 11 is placed in the water, and the detection box 3 is also placed in the water. Then the navigation component 11 is controlled to operate by the remote control device. The rotation of the navigation component 11 can push the float 1 to move on the water surface. During the movement, the float 1 drives the fixed frame 2 to move, and the fixed frame 2 drives the detection box 3 to move in the water through the threaded rod 221. During the movement, water is poured into the interior of the detection box 3, and multiple water quality detection sensors inside the detection box 3 detect the poured water. The detection results are transmitted to the remote control device. During the detection process, water in different water layers needs to be detected. At this time, the motor 23 is started to drive the output gear 21 rotates, and when the output gear 21 rotates, it drives the gear sleeves 22 on both sides to rotate. When the gear sleeves 22 rotate, it drives the threaded rod 221 in the middle to move up and down. At this time, the threaded rod 221 drives the detection box 3 to move up and down to adjust its current depth in the water. After adjusting to different depths, the detection box 3 is filled with water from the water layer of the depth and detected by the water quality detection sensor, so that the water quality data of different water layers can be obtained. During the movement of the detection box 3, the connecting column 42 at the bottom thereof will be driven to move, and the connecting column 42 drives the upper support rod 4 to move. When the upper support rod 4 touches the bottom, it will push the connecting column 42, and the connecting column 42 pushes the pressure sensor. When the pressure reaches the preset value, the detection box 3 stops descending, and the detection box 3 is raised away from the silt area, so as to prevent the bottom silt from mixing into the water and affecting the accuracy of the detection data.

[0033] like Figures 1 to 7As shown, sealing balls 31 are provided at both ends of the detection box 3, the outer diameter of the sealing ball 31 is larger than the inner diameter of the openings at both ends of the detection box 3, a flip arm 312 is fixed on one side of the sealing ball 31 close to the detection box 3, and support blocks 33 are fixed on both sides of the top of the detection box 3, and the flip arm 312 is rotatably connected between the support blocks 33;

[0034] When the upper support rod 4 touches the bottom of the water, it will be pushed. At this time, the flip arm 312 rotates inside the support block 33, and the flip arm 312 drives the sealing ball 31 to move. At this time, the sealing ball 31 moves into the openings at both ends of the detection box 3. The sealing ball 31 can block the openings of the detection box 3. At this time, the interior of the detection box 3 can be isolated to prevent water mixed with silt from entering the interior of the detection box 3.

[0035] like Figures 1 to 4 As shown, a first connection seat 41 is fixed to the bottom end of the connection column 42, and the first connection seat 41 is rotatably connected to one end of the upper support rod 4;

[0036] The four upper support rods 4 can be connected together through the first connecting seat 41. When the upper support rods 4 touch the bottom of the water, the contact area and range are larger, which can make it easier for the upper support rods 4 to be supported on the bottom of the water.

[0037] like Figures 1 to 4 As shown, the other end of the upper support rod 4 is hinged with a lower support rod 43 through a connecting block, and the other end of the lower support rod 43 is rotatably connected to a lower connecting seat 432, and a telescopic column 433 is fixed to the top of the lower connecting seat 432, and the telescopic column 433 runs through the interior of the first connecting seat 41, and a telescopic hole 421 is provided in the interior of the connecting column 42, and the top of the lower support rod 43 is inserted in the telescopic hole 421, and a pull rope 434 is fixed on both sides of the top of the telescopic column 433, and holes for the pull rope 434 to be telescoped are provided on both sides of the connecting column 42, and the other end of the pull rope 434 is fixedly connected to the end of the sealing ball 31 away from the flip arm 312;

[0038] When the upper support rod 4 contacts the bottom of the water downward, the bottom of the water pushes the lower connecting seat 432 and the lower supporting rod 43, and the lower supporting rod 43 drives the upper supporting rod 4 to rotate at the same time. At this time, the lower connecting seat 432 is pushed close to the first connecting seat 41, and the lower connecting seat 432 pushes the telescopic column 433 to telescope inside the telescopic hole 421. At this time, the telescopic column 433 pulls the pull rope 434 into the telescopic hole 421. When the pull rope 434 is pulled, it will also pull the sealing ball 31, and the sealing ball 31 will be moved in the flip arm 3 12 and the support block 33, it will move toward the two ends of the detection box 3. When the telescopic column 433 reaches the top of the telescopic hole 421, the sealing ball 31 is pulled into the interior of the openings at both ends of the detection box 3. At this time, the interior of the detection box 3 can be sealed to prevent water mixed with silt from entering the interior of the detection box 3. When the upper support rod 4 and the lower support rod 43 leave the bottom of the water, the lower connecting seat 432 can drive the telescopic column 433 to return to its original position under the action of gravity. At this time, the sealing ball 31 will automatically reset due to buoyancy.

[0039] like Figures 1 to 4 As shown, movable columns 413 are fixed on both sides of the upper support rod 4 near one end of the first connecting seat 41, an upper limit block 411 is arranged above the movable column 413, and a lower limit block 412 is arranged below the movable column 413, and both the upper limit block 411 and the lower limit block 412 are fixedly connected to the first connecting seat 41;

[0040] When the upper support rod 4 rotates outside the first connecting seat 41, the movable column 413 moves between the upper limit block 411 and the lower limit block 412. The upper limit block 411 can limit the upward moving range of the movable column 413, and the lower limit block 412 can limit the downward moving range of the movable column 413, which can prevent the upper support rod 4 from moving too much and making it inconvenient to support the bottom of the water.

[0041] like Figures 1 to 4 As shown, a cutter 431 is fixed to the top of the cutter 431, and a cut groove 44 is provided at the bottom end of the upper support rod 4, and the cutter 431 and the cut groove 44 can be engaged with each other;

[0042] After the upper support rod 4 touches the bottom of the water, it may be entangled by long objects. After the lower support rod 43 is supported by the bottom of the water, the space between the lower support rod 43 and the upper support rod 4 will be closed. At this time, the cutter 431 and the cutting groove 44 can cut off the long objects entangled on the outside of the upper support rod 4 or the lower support rod 43. The long objects entangled on the outside of the upper support rod 4 and the lower support rod 43 will be driven by the opening process of the upper support rod 4 and the lower support rod 43 during the rising process of the upper support rod 4 and the lower support rod 43, so that they will fall off from the outside of the upper support rod 4 and the lower support rod 43, which can prevent the outside of the upper support rod 4 and the lower support rod 43 from being entangled by long objects.

[0043] like Figures 1 to 6As shown, a vent hole 311 is provided at the bottom end of the sealing ball 31, a one-way valve is installed inside the vent hole 311, an air supply pipe 313 is provided above the flip arm 312, one end of the air supply pipe 313 is connected to the inside of the sealing ball 31, and a plurality of drainage holes 32 are provided at the bottom end of the detection box 3, and a one-way valve is installed inside the drainage hole 32;

[0044] During the process of the detection box 3 moving up and down to adjust the depth, water of a certain previous depth will be retained inside the detection box 3, which will cause inaccurate detection data. Therefore, during the lifting process, the sealing ball 31 is used to block the openings at both ends of the detection box 3, and then air is input into the sealing ball 31 through the air supply pipe 313. The one-way valve plate inside the exhaust hole 311 will be pushed open by the gas inside the sealing ball 31. At this time, the gas enters the interior of the detection box 3 through the exhaust hole 311, and the gas pushes the water inside the detection box 3. At this time, the one-way valve plate inside the drainage hole 32 is pushed open by the water, and the water inside the detection box 3 can be discharged to the outside. When the detection box 3 stops moving, the air supply pipe 313 stops supplying gas. At this time, the one-way valve plate of the exhaust hole 311 is closed, and the sealing ball 31 will rise and reset due to buoyancy, so that the inside of the detection box 3 can be drained.

[0045] like Figures 1 to 8 As shown, both sides of the top of the detection box 3 are fixed with an air guide shell 34, a piston 342 is arranged inside the air guide shell 34, an air outlet 341 is fixed on the top of the air guide shell 34, a one-way valve is installed inside the air outlet 341, a push column 343 is fixed on the end of the piston 342 close to the air outlet 341, the push column 343 runs through one side of the air guide shell 34, a push block 345 is fixed on the end of the push column 343 away from the piston 342, the outer side of the push block 345 is rotatably connected to a push arm 346, and the other end of the push arm 346 The end is rotatably connected with the end of the flip arm 312 away from the sealing ball 31, and a transmission gear 24 is arranged on the side of the floating ball 1 close to the fixed frame 2. The transmission gear 24 is rotatably connected to the top of the fixed frame 2, and the transmission gear 24 is meshed and connected with the output gear 21. The top of the transmission gear 24 is rotatably connected with a connecting arm 241, and the other end of the connecting arm 241 is rotatably connected with an inflatable cylinder 242. The bottom end of the inflatable cylinder 242 is fixedly connected with the fixed frame 2, and the inflatable cylinder 242 and the air guide shell 34 are connected through an air guide pipe 243.

[0046] When the output gear 21 drives the gear sleeve 22 to rotate, the detection box 3 can be raised and lowered. At this time, the output gear 21 drives the transmission gear 24 to rotate at the same time. The rotation of the transmission gear 24 drives the inflation cylinder 242 to pump air. The inflation cylinder 242 pumps the gas into the interior of the gas guide shell 34 through the air guide pipe 243. At this time, the piston 342 is pushed by the gas, and the piston 342 pushes the push column 343 to drive the push block 345. The push block 345 pushes the push arm 346 to enable the flip arm 312 to drive the sealing ball 31 to rotate. When the sealing ball 31 rotates 90°, the opening of the detection box 3 can be blocked. When the sealing ball 31 rotates 90°, the piston 342 moves to the rear of the air outlet 341. At this time, the interior of the air outlet 341 can be ventilated, and the air outlet 341 inputs the gas into the interior of the sealing ball 31 through the air supply pipe 313. At this time, the sealing ball 31 can input gas into the interior of the detection box 3 through the exhaust hole 311, and the internal drainage of the detection box 3 can be completed automatically.

[0047] like Figures 1 to 8 As shown, a spring 344 is sleeved on the outside of the push column 343, one end of the spring 344 is fixedly connected to one end of the piston 342 close to the air outlet 341, and the other end of the spring 344 is fixedly connected to the inner side of the air guide housing 34;

[0048] After adjustment, the output gear 21 stops rotating, and the transmission gear 24 stops rotating. The elastic force of the spring 344 pushes the piston 342 to reset. Meanwhile, the buoyancy of the sealing ball 31 assists the sealing ball 31 to reset. At this time, water can be restored to both ends of the detection box 3.

[0049] like Figures 1 to 8 As shown, a gas storage bottle 244 is provided between the air guide tube 243 and the gas cylinder 242, the top end of the gas storage bottle 244 is fixedly connected to the gas cylinder 242, and the bottom end of the gas storage bottle 244 is fixedly connected to the air guide tube 243;

[0050] The inflator 242 pumps air once every time the transmission gear 24 rotates one circle. In order to prevent the sealing ball 31 from being reset due to lack of gas during the intermediate rotation of the transmission gear 24, a gas storage bottle 244 is provided. The gas storage bottle 244 can temporarily store the gas pumped out by the inflator 242, and input the gas into the air guide tube 243 through the gas storage bottle 244. The gas stored in the gas storage bottle 244 can be supplied to the air guide tube 243 during the process of the inflator 242 being evacuated, which can prevent the sealing ball 31 from being reset due to gas interruption when the inflator 242 is evacuated.
