DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] For example, see Figure 1-5A water quality detection and water intake device comprises a water intake cylinder 1, a water inlet 2 is fixedly installed on the side of the water intake cylinder 1, a sealing cover 3 is movably connected to the top of the water intake cylinder 1, a lead block 14 is fixedly installed on the bottom of the water intake cylinder 1, a spiral torsion rod 4 is threadedly connected to the sealing cover 3, a sliding column 15 is fixedly installed on the bottom of the water intake cylinder 1, a cone head 6 is slidably sleeved on the sliding column 15, a touch switch 17 is fixedly installed on the bottom of the water intake cylinder 1, a motor 12 is embedded on the side of the water intake cylinder 1, the touch switch 17 is electrically connected to the motor 12, an ordinary gear 22 is fixedly installed on the output shaft of the motor 12, a control water outlet 13 is fixedly installed on one end of the water inlet 2 located inside the water intake cylinder 1, two slide plates 18 are slidably connected to the side of the control water outlet 13, and cylinders 19 are fixedly installed on the sides of the two slide plates 18, and the cylinders 19 are rotatably and slidably connected with a rotating gear 20, the rotating gear 20 is rotatably connected to the control water outlet 13, the rotating gear 20 is meshed with the ordinary gear 22, and the rotating gear 20 is fixedly installed on the side The through hole 21, a partition 10 is fixedly installed inside the water-taking cylinder 1, and the partition 10 and the through hole 21 are rotatably connected. A rubber piston 9 is fixedly installed at the bottom of the spiral torsion bar 4, a spring 16 is wound around the outside of the sliding column 15, and a sealing ring is fixedly installed on the upper side of the sealing cover 3 and the contact part of the spiral torsion bar 4. Two arc-shaped grooves with central symmetry are opened on the rotating gear 20. The motor 12 is a bidirectional asynchronous motor and has a built-in timing program. The motor 12 can be reversely turned on by the timing program after the water is taken, so as to seal the inside of the water-taking cylinder 1. The device is arranged by the cooperation of the spiral torsion bar 4 and the sealing cover 3. When the spiral torsion bar 4 is rotated, the rubber piston 9 is driven to move upward at a uniform speed. At this time, negative pressure is formed inside the water-taking cylinder 1. Putting the device into the water area to be taken can make water enter the water-taking cylinder 1 under the influence of negative pressure, thereby avoiding the influence of internal air on water. At the same time, through the cooperation of the cone head 6 and the touch switch 17, the device automatically starts to take water after touching the bottom, without excessive human intervention, which saves time.

[0024] When in use, the initial position of the rubber piston 9 is located at the lowest end of the water intake cylinder 1. The spiral torsion rod 4 is rotated to make the spiral torsion rod 4 withdrawn from the sealing cover 3, and at the same time, the rubber piston 9 is driven to move upward at a uniform speed. At this time, negative pressure is formed inside the water intake cylinder 1, and the device is placed in the water area to be taken. Because the cone head 6 and the lead block 14 at the bottom of the device have a large gravity, the device sinks vertically to the bottom of the water. The cone head 6 enables the device to be inserted into the muddy area at the bottom of the water area. At the same time, due to the gravity of the lead block 14, after the cone head 6 stops moving, the lead block 14 will continue to move downward due to inertia, and the inertia is greater than the elastic potential energy of the spring 16, so that the lead block 14 moves downward and moves downward along the sliding column 15. At this time, the lead block 14 contacts the cone head 6, triggering the touch switch 17. The touch switch 17 causes the output shaft of the motor 12 to rotate counterclockwise, driving the general The through gear 22 rotates counterclockwise, and drives the rotating gear 20 to rotate clockwise through gear meshing. The initial positions of the slide plates 18 are close to each other. At this time, the cylinder 19 is located at one end of the arc groove opened on the rotating gear 20 close to the through hole 21. When the rotating gear 20 rotates clockwise, the cylinder 19 moves away from the through hole 21 along the arc groove, so that the slide plate 18 is no longer close to each other, and the water outlet 13 is controlled to lose the restriction of the slide plate 18. At the same time, because the inside of the water intake cylinder 1 is in a negative pressure state, the water from the external water area enters the water intake cylinder 1 through the water inlet 2. The motor 12 is set with a timer, and after the specified time is reached, the output shaft of the motor 12 rotates clockwise, and the rotating gear 20 rotates counterclockwise through the cooperation of the ordinary gear 22, so that the slide plates 18 are close to each other until they are closed, and the collected water is retained in the water intake cylinder 1.

[0025] For example 2, please refer to Figure 4-6On the basis of the first embodiment, the sealing cover 3 is embedded with a compressed air bag 5, the bottom of the compressed air bag 5 is clamped and connected with a compressed air tank 24, the connection between the compressed air tank 24 and the compressed air bag 5 is slidably connected with a plug plate 30, a plurality of ratchet claws 25 are fixedly installed on the output shaft of the motor 12, a rotating ring 26 is rotatably connected to the side of the motor 12 close to the ratchet claw 25, a plurality of movable claws 27 are rotatably connected to the rotating ring 26, a rotating disk 23 is rotatably connected to the inner wall side of the water taking cylinder 1, the rotating disk 23 and the rotating ring 26 are connected by a transmission belt 28, the rotating disk 23 is rotatably connected with a transmission rod 29, and the end of the transmission rod 29 away from the rotating disk 23 is rotatably connected to the plug plate 30, when the output of the motor 12 drives the ratchet claw 25 to rotate counterclockwise, the ratchet claw 2 5 will not engage with the movable claw 27. Only when the pawl 25 rotates clockwise can the movable claw 27 be driven to rotate. The pawl 25 is in contact with the movable claw 27 but not connected. The maximum rotation angle of the movable claw 27 is sixty degrees. The width of the plug plate 30 is greater than the diameter of the air outlet pipe of the compressed gas tank 24. The plug plate 30 completely blocks the air outlet of the compressed gas tank 24. When the plug plate 30 moves, the high-pressure gas inside the compressed gas tank 24 will enter the compressed air bag 5, and the output shaft of the motor 12 drives the pawl 25 to rotate, so that the pawl 25 is engaged with the movable claw 27 when it rotates clockwise, driving the rotating disk 23 to rotate, thereby pulling out the plug plate 30, realizing the automatic inflation of the compressed air bag 5, and the buoyancy of the compressed air bag 5 drives the entire device to float upward, which is convenient for users to recover.

[0026] During use, based on the first embodiment, when the output shaft of the motor 12 rotates clockwise, the pawl 25 on the output shaft rotates clockwise, so that the pawl 25 and the movable pawl 27 are engaged with each other, so that the pawl 25 drives the rotating ring 26 to rotate clockwise. When the output shaft of the motor 12 drives the pawl 25 to rotate counterclockwise, the pawl 25 will not be engaged with the movable pawl 27. Only when the pawl 25 rotates clockwise can it drive the movable pawl 27 to rotate. The rotating disk 23 is rotated by the transmission of the transmission belt 28. When the rotating disk 23 rotates, it drives the transmission rod 29 to rotate. During the rotation of the transmission rod 29, the plug plate 30 is driven away from the compressed gas tank 24, so that the outlet at the top of the compressed gas tank 24 is unrestricted, and the high-pressure gas inside the compressed gas tank 24 enters the compressed air bag 5. The compressed air bag 5 expands upward and thus detaches from the sealing cover 3. Driven by the buoyancy of the compressed air bag 5, the entire device floats upward, which is convenient for users to recover.

[0027] For example 3, please refer to Figure 1-7On the basis of the first embodiment, an upper collar 7 is fixedly installed on the lower part of the side of the water intake cylinder 1, a lower collar 8 is fixedly installed on the outer side of the cone head 6 close to the water intake cylinder 1, an elastic fastener 31 is fixedly installed on the bottom of the upper collar 7, and a clamp 32 is fixedly installed on the top of the lower collar 8. The elastic fastener 31 and the clamp 32 correspond to each other and are movably connected. A rubber inflation tube 33 is fixedly installed on the top of the lower collar 8, and an extrusion gas chamber 11 is fixedly installed on the upper part of one side of the partition 10 close to the spiral torsion rod 4. The extrusion gas chamber 11 and the rubber inflation tube 33 are connected through a connecting pipe. The elastic fastener 31 and the clamp 32 connect the upper collar 7 and the lower collar 8 to each other, so that the upper collar 7 and the lower collar 8 protect the connecting part of the water intake cylinder 1 and the cone head 6. A raised block is fixedly installed on the side of the rubber inflation tube 33. The raised block is located on the side of the clamp 32 close to the elastic fastener 31 and contacts the elastic fastener 31. When the rubber inflation tube 33 expands, it drives the raised block on the side to push out inward, pushing out the elastic fastener 31, so that the elastic fastener 31 and the clamp 32 are separated. The device protects the connecting part of the water intake cylinder 1 and the cone head 6 through the upper ring 7 and the lower ring 8 to avoid damage to the slide column 15 when the device is not in use. At the same time, it can also effectively prevent the water intake cylinder 1 and the cone head 6 from touching each other, and avoid accidentally touching the touch switch 17. When it is needed, the spiral torsion rod 4 is rotated upward to compress and squeeze the air chamber 11, so that the elastic fastener 31 and the clamp 32 are separated. At this time, the device can be used normally.

[0028] When in use, based on the first embodiment, in the initial state, the elastic fastener 31 and the clamping member 32 are clamped with each other, so that the upper ring 7 and the lower ring 8 are connected to each other, so that the upper ring 7 and the lower ring 8 protect the connecting part of the water intake tube 1 and the cone head 6, and at the same time prevent the water intake tube 1 and the cone head 6 from touching each other, and avoid accidentally touching the touch switch 17. When the device needs to be used, the spiral torsion rod 4 is first rotated to drive the rubber piston 9 to move upward. When it moves to a certain distance, it will squeeze the extrusion gas chamber 11, so that the gas in the extrusion gas chamber 11 enters the rubber inflation tube 33 through the connecting tube, so that the rubber inflation tube 33 expands and drives the convex block on the side to push out inward, pushing out the elastic fastener 31, so that the elastic fastener 31 and the clamping member 32 are separated. At this time, the upper ring 7 and the lower ring 8 are no longer connected, and the water intake tube 1 and the cone head 6 move away from each other under the action of the spring 16. At this time, the water intake tube 1 and the cone head 6 can slide through the sliding column 15, which is convenient for triggering the touch switch 17.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
