Description

Technical Field

[0001] The present invention relates to the technical field of water quality monitoring equipment, and more specifically to a multi-depth water quality monitoring device based on satellite remote sensing. Background Art

[0002] With the progress of society and the continuous development of industrial production, a large amount of industrial pollution will be caused, including industrial waste gas, industrial waste water, etc. The direct discharge of industrial waste gas or industrial waste water will cause damage to the environment and affect people's health. When discharging industrial waste water, some illegal companies will directly discharge the waste water into the river. Since industrial waste water contains more heavy metals or other pollutants, when industrial waste water flows in the river, it is at a lower position below the water surface in the river, so it cannot be directly detected, affecting the ecological environment.

[0003] In the prior art, satellite remote sensing technology can be used to monitor whether there is pollution in the water area. The satellite transmits signals and remotely controls the water below the river to be pumped into a water quality detector for testing. When taking water, the pumping pipe is first fixed at a position below the water surface in the river, and then the pump is started to pump out the river water for testing, and the monitoring results are transmitted via satellite signals. However, there are some problems in its use. It is impossible to sample river water at different depths in the river. When industrial wastewater flows in the river, it will mix with the river water, resulting in differences in the number and weight of pollutants in the river water at different depths. The samples obtained are small, which will affect the test results, making the test results inaccurate, and thus it is impossible to accurately judge whether there is more serious pollution in the river.

The above-mentioned belong to the prior art and will not be described in detail here. The first fixed shaft 5 is placed above the first fixed platform 4, and the through hole 77 is concentrically corresponding to the threaded hole 78. The lower end of the bolt is passed through the through hole 77 and screwed into the threaded hole 78 to fix the first fixed shaft 5. The second fixed shaft 14 is placed above the second fixed platform 13, and the through hole 77 is concentrically corresponding to the threaded hole 78.

[0046] The second gear 7 and the eccentric wheel 8 are installed on the first fixed shaft 5 through the first rolling bearing 6, so that when the second gear 7 and the eccentric wheel 8 rotate, they will not drive the first fixed shaft 5 to rotate. The third gear 16 and the first bevel gear 17 are installed on the second fixed shaft 14 through the second rolling bearing 15, so that when the third gear 16 and the first bevel gear 17 rotate, they will not drive the second fixed shaft 14 to rotate. Starting the speed regulating motor 2 to reverse can drive the first gear 3 to rotate. The first gear 3 is respectively engaged with the second gear 7 and the third gear 16, which can drive The second gear 7 and the third gear 16 are driven to rotate. When the speed regulating motor 2 reverses to drive the second gear 7 and the third gear 16 to rotate, the first spring ejector pin 11 on the second gear 7 causes the first universal ball 12 to enter the lower end of the first arcuate serrated groove 10 under the action of its own elastic force. When the second gear 7 rotates, the lower end of the first spring ejector pin 11 moves toward the lower end in the first arcuate serrated groove 10 and is intercepted by another higher first arcuate serrated groove 10, thereby driving the first annular interception platform 9 to rotate, driving the eccentric wheel 8 to rotate. When the speed regulating motor 2 reverses and drives the second gear 7 and the third gear 16 to rotate, the second spring ejector pin 20 on the third gear 16 pushes the second universal ball 21 into the lower end of the second arc-shaped sawtooth groove 19 under the action of its own elastic force. When the third gear 16 rotates, the lower end of the second spring ejector pin 20 moves from the lower end to the higher end in the second arc-shaped sawtooth groove 19, thereby compressing the second spring ejector pin 20. When the lower end of the second spring ejector pin 20 passes the highest point of the second arc-shaped sawtooth groove 19, it falls into the lower The lower end of the second arc-shaped sawtooth groove 19 will not drive the second annular interception platform 18 to rotate, and the first bevel gear 17 will not rotate. The rotation of the first universal ball 12 and the second universal ball 21 can reduce the friction between the first spring thimble 11 and the second spring thimble 20 when they move. Therefore, when the speed regulating motor 2 is reversed, the eccentric wheel 8 can be driven to rotate, and the first bevel gear 17 will not rotate. Similarly, when the speed regulating motor 2 is forward, the first bevel gear 17 can be driven to rotate, and the eccentric wheel 8 will not rotate.

[0047] When the speed regulating motor 2 is started to reverse and drive the eccentric wheel 8 to rotate, when the end of the outer side of the eccentric wheel 8 farthest from the center of the cross section of the first fixed axis 5 rotates to the top, the lifting platform 22 will be pushed up to the highest point. The moving direction of the lifting platform 22 can be guaranteed by the guide column 26 and the guide hole 25. The multiple pulleys 24 on the side surface of the eccentric wheel 8 and the arc-shaped groove 23 on the lower surface of the lifting platform 22 can reduce the friction between the eccentric wheel 8 and the lifting platform 22. When the end of the outer side of the eccentric wheel 8 closest to the center of the cross section of the first fixed axis 5 rotates to the bottom, the lifting platform 22 moves downward under the action of gravity, thereby lowering its own position. The continuous rotation of the eccentric wheel 8 can make the lifting platform 22 rise and fall continuously. When the lifting platform 22 rises and falls, the limit platform 2 The limiting groove 28 on 7 can move the lifting gear 36, and the lifting gear 36 is sleeved on the square connecting shaft 33 through the square through hole 37, so that the lifting gear 36 can be lifted and lowered on the square connecting shaft 33. The height of the lifting platform 22 is detected by the infrared rangefinder 76, and the lifting gear 36 is adjusted to a position meshing with the second output gear 42. When the reduction motor 2 reverses to drive the eccentric wheel 8 to rotate, it will drive the ratchet 55 to rotate. At this time, the pawl 56 will not exert a force on the ratchet 55. When the reduction motor 2 is turned off or rotated forward, the eccentric wheel 8 will rotate under the action of its own gravity and a small amount of friction force given to the first annular interception platform 9 by the first universal ball 12 when the reduction motor 2 rotates forward. At this time, the ratchet 55 is intercepted by the pawl 56 to prevent the eccentric wheel 8 from reversing.

[0048] After the lifting gear 36 is meshed with the second output gear 42, the speed regulating motor 2 is started to rotate forward. At this time, the first bevel gear 17 will be driven to rotate. The first bevel gear 17 is meshed with the second bevel gear 35, which can drive the square connecting shaft 33 and the cylindrical connecting shaft 34 to rotate between the third rolling bearing 30 and the fourth rolling bearing 32. The square connecting shaft 33 will drive the lifting gear 36 to rotate. When the lifting gear 36 rotates, the friction between the lifting gear 36 and the limit platform 27 can be reduced by the third universal ball 29. At this time, the lifting gear 36 is meshed with the second output gear 42, and the second output gear 42 is meshed with the fourth gear 48, thereby driving the lead screw 47 to rotate forward. The lead screw 47 is sleeved with a lifting block 52 through a threaded connection. One end of the lifting block 52 extends into the guide groove 53. When the lead screw 47 rotates, the lifting block 52 can be moved upward, and the floating ball on the floating ball liquid level sensor 54 is driven to move by the lifting block 52. The water level depth is detected by the floating ball liquid level sensor 54. When the first transmission wheel 49 rotates, it will drive the first transmission wheel 49 to rotate. The first transmission wheel 49 drives the second transmission wheel 50 to rotate through the transmission belt 51, thereby driving the second transmission wheel 50 and the third output gear 43 to rotate. Since the fourth gear 48 and the first transmission wheel 49 are both mounted on the lead screw 47, the angular velocity of the two rotations is the same. The fourth gear 48 and the second output gear 42 are of the same model and meshed. The second transmission wheel 50 is mounted on the third output gear 43. The second transmission wheel 50 and the first transmission wheel 49 have the same outer diameter. When the second output gear 42 rotates a certain number of circles, the third output gear 43 rotates the same number of circles. After adjusting the lifting block 52 to a suitable position, the rotation of the speed regulating motor 2 is reduced. When the infrared transmitter 74 under the second bevel gear 35 rotates to the top of the infrared receiver 75 and sends an infrared signal that is received by the infrared receiver 75, the speed regulating motor 2 is turned off, thereby positioning the lifting gear 36, the second output gear 42, and the third output gear 43.

[0049] When it is necessary to lower the position of the lifting block 52, the speed regulating motor 2 is started to reverse and drive the eccentric wheel 8 to rotate, so as to lower the position of the lifting platform 22. The distance is detected by the infrared rangefinder 76, and the lifting gear 36 is adjusted to a position that meshes with the third output gear 43. The speed regulating motor 2 is started to rotate forward and drive the third output gear 43 to rotate. The second transmission wheel 50 under the third gear 43 drives the first transmission wheel 49 to rotate through the conveyor belt 51, so that the lead screw 47 is reversed, and the position of the lifting block 52 is lowered, so as to adjust the height of the water intake. When the first output gear 41, the second output gear 42, and the third output gear 43 are installed, they are all in a position that can mesh with the lifting gear The first output gear 41, the second output gear 42 and the third output gear 43 are driven to rotate by the rotation of the lifting gear 36. When the lifting gear 36 stops rotating, the infrared transmitter 74 is above the infrared receiver 75, which can ensure that the first output gear 41, the second output gear 42 and the third output gear 43 are always in a position where they can be engaged with the lifting gear 36. The first output gear 41, the second output gear 42 and the third output gear 43 can not rotate when the lifting gear 36 does not rotate through the resistance connected with other gears.

[0050] When it is necessary to draw water, the speed regulating motor 2 is started to reverse, driving the eccentric wheel 8 to rotate, adjusting the lifting gear 36 to a position meshing with the first output gear 41, the first output gear 41 meshes with the fifth gear 68, and the speed regulating motor 2 is started to rotate forward, which can drive the fifth gear 68 and the transmission shaft 66 to rotate between the two seventh rolling bearings 65, and drive the fourth bevel gear 67 to rotate, the fourth bevel gear 67 meshes with the third bevel gear 63, and can drive the rotating shaft 61 to rotate between the two waterproof bearings 60. An impeller 62 is installed at one end of the rotating shaft 61, so that the impeller 62 can be driven to rotate in the water intake pipe 58, and water can be extracted through the water intake pipe 58 and the telescopic hose 59. The protective cover on the telescopic hose 59 The net 79 can prevent larger impurities such as leaves and plastic from entering and clogging it. When the lifting block 52 is lifted or lowered, it can drive the inlet end of the telescopic hose 59 to lift or lower below the water surface, so that water at different water levels can be extracted. The water in the water intake pipe 58 flows into the water container 70 through the outlet pipe 71 and is discharged through the drain pipe 72. The water outlet speed of the outlet pipe 71 is greater than the water outlet speed of the drain pipe 72. When a certain amount of water is placed in the water container 70, the water quality detector 69 is started. The water quality can be monitored by placing a probe of the water quality detector 69 in the water container 70. When the water quality is poor, an alarm is sounded through the water quality detector 69, and relevant personnel are sent to handle it, thereby protecting the natural environment.

Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
