DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-6 , the utility model provides a technical solution:

[0029] A portable water quality detection structure for environmental monitoring comprises an airbag 1, a bracket 2 is fixedly connected to the outside of the airbag 1, a tether 3 is provided at the bottom of the bracket 2, a detection component 4 is provided at the outside of the tether 3, and an anchor 5 is fixedly connected to the bottom of the tether 3;

[0030] The detection component 4 includes a ballast chamber 401, a piston plate 402 is slidably connected to the inner side of the ballast chamber 401, an isolation plate 403 is fixedly connected to the inner side of the ballast chamber 401, a sealing shell 404 is fixedly connected to the inner side of the ballast chamber 401, an electrochemical sensor 405 is fixedly connected to the inner side of the sealing shell 404, an inner frame 406 is fixedly connected to the inner side of the ballast chamber 401, a limiting component 407 is fixedly connected to the inner side of the inner frame 406, a probe of the electrochemical sensor 405 extends out of the ballast chamber 401 and is fixedly connected to the ballast chamber 401 through a seal, and a flow groove is opened on the inner side of the ballast chamber 401.

[0031] In this embodiment: the airbag 1 is provided to provide buoyancy, so that the bottom structure can be connected through the bracket 2 or the connection of the ship carrier can be detected when necessary. After the anchor 5 is dropped, the position of the structure can be fixed in the detection area. After the ship moves away, the position of the structure can also be observed through the position of the airbag 1 for easy recovery. After the gas in the airbag 1 is discharged, the volume can be kept small to facilitate the structure to be carried. The detection component 4 can adjust the position of the piston plate 402 in the ballast chamber 401 to adjust the pressure difference between the inside and outside of the ballast chamber 401, and extract water in the detection environment from the circulation groove. When the amount of water in the ballast chamber 401 increases, the overall weight increases, so the buoyancy decreases, and sinking will occur at this time. Therefore, the water quality at different depths can be monitored by the electrochemical sensor 405. When the piston plate 402 is pushed down along the ballast chamber 401, the water will be discharged from the ballast chamber 401 to reduce the weight and increase the buoyancy, so that the entire detection component 4 moves up for easy recovery.

[0032] Specifically, Figure 4 As shown, the limiting assembly 407 includes an outer retaining wheel 407a and an inner retaining wheel 407b, the outer side of the inner retaining wheel 407b is in contact with the outer retaining wheel 407a, and the tether 3 is arranged between the inner retaining wheel 407b and the outer retaining wheel 407a.

[0033] Specifically, Figure 4 As shown, the inner sides of the outer clamping wheel 407a and the inner clamping wheel 407b are both rotatably connected with the wheel axle 407c.

[0034] Specifically, Figure 4 As shown, the outer side of the left wheel axle 407c is fixedly connected to a surrounding frame 407d, the left side of the surrounding frame 407d is fixedly connected to the inner frame 406, the inner side of the surrounding frame 407d is movably connected to a drawer 407e, and the drawer 407e is fixedly connected to the outer side of the right wheel axle 407c.

[0035] In this embodiment: by setting the outer retaining wheel 407a to cooperate with the inner retaining wheel 407b, when the detection component 4 produces a vertical displacement due to the change of its own buoyancy, the outer retaining wheel 407a and the inner retaining wheel 407b can be rotated on the outside of the tether 3 to limit it, so as to avoid the loss of the structure due to the water flow, and at the same time, the device can be moved relatively vertically along the tether 3. The outer retaining wheel 407a and the inner retaining wheel 407b can rotate smoothly through the wheel axle 407c, and the outer retaining wheel 407a and the inner retaining wheel 407b are firmly connected through the surrounding frame 407d and the drawer 407e. Moving the drawer 407e along the surrounding frame 407d can also facilitate the extension of the space between the outer retaining wheel 407a and the inner retaining wheel 407b, so as to facilitate the use with tethers 3 of different diameters.

[0036] Specifically, Figure 5 As shown, a tension spring 6 is fixedly connected to the inner side of the surrounding frame 407d, and the tension spring 6 is fixedly connected to the inner side of the drawer frame 407e.

[0037] Specifically, Figure 3 As shown, the bottom of the ballast chamber 401 is fixedly connected with a secondary cable 7 , the bottom of the secondary cable 7 is fixedly connected with a counterweight 8 , and the counterweight 8 is arranged on the outside of the tether 3 .

[0038] In this embodiment: by setting a tension spring 6, the spring is stretched and deformed when the drawer 407e is pulled out along the surrounding frame 407d, and is reset when the pulling out stops, so that the drawer 407e and the surrounding frame 407d are always in a coordinated state. The auxiliary cable 7 is used to install the counterweight block 8, and the counterweight block 8 further limits the position of the detection component 4 relative to the tether rope 3, and lowers its center of gravity so that it can maintain a relatively horizontal state for lifting and lowering.

[0039] Specifically, Figure 2 As shown, a connecting buckle 9 is fixedly connected to the bottom of the bracket 2, a stabilizing rope 10 is fixedly connected to the bottom of the connecting buckle 9, and the bottom of the stabilizing rope 10 is fixedly connected to the tether rope 3.

[0040] Specifically, Figure 3As shown, the top of the ballast chamber 401 is fixedly connected to the top shell 11, the inner side of the top shell 11 is fixedly connected to the slide rod 12, the outer side of the slide rod 12 is slidably connected to the movable plate 13, the bottom of the movable plate 13 is fixedly connected to the control motor 14, the output end of the control motor 14 is fixedly connected to the screw rod 15, the outer side of the screw rod 15 is threadedly connected to the top of the ballast chamber 401, and the bottom of the screw rod 15 is rotatably connected to the piston plate 402 through a bearing.

[0041] In this embodiment: by setting a connecting buckle 9 in conjunction with a stabilizing rope 10, the structure can be easily connected. Multiple connection points at the bottom of the bracket 2 can also prevent the airbag 1 and the bracket 2 from overturning due to uneven force. The set slide rod 12 is used to install a control motor 14 in conjunction with the top shell 11 and the movable sheet 13. The control motor 14 provides power, and when the drive screw rod 15 rotates, the screw rod 15 pushes the piston plate 402 in the ballast chamber 401 to move, so as to drive the ballast chamber 401 to absorb and drain water.

[0042] Working principle: When in use, the airbag 1 can be inflated to provide buoyancy, and the anchor 5 can be dropped to the detection position. When detection is required, the electrochemical sensor 405 keeps detecting the water in contact with the probe. When the detection water depth needs to be changed, the start control motor 14 can control the screw rod 15 to rotate to drive the piston plate 402 connected thereto to move vertically, and adjust the position of the piston plate 402 in the ballast chamber 401 to adjust the pressure difference inside and outside the ballast chamber 401, and extract water from the detection environment from the circulation groove. When the amount of water in the ballast chamber 401 increases, the overall weight increases, so the buoyancy decreases, and sinking will occur at this time. Therefore, the water quality conditions at different depths can be monitored by the electrochemical sensor 405 In this case, when the detection component 4 produces a vertical displacement due to the change in its own buoyancy, the outer clamping wheel 407a and the inner clamping wheel 407b rotate on the outside of the tether 3 to limit it, thereby preventing the structure from being lost due to the water flow, and at the same time allowing the device to move relatively vertically along the tether 3. The outer clamping wheel 407a and the inner clamping wheel 407b can rotate smoothly through the wheel axle 407c. When the piston plate 402 is pushed down along the ballast chamber 401, water will be discharged from the ballast chamber 401 to reduce the weight and increase the buoyancy, so that the entire detection component 4 moves up for easy recovery. When it is necessary to recover the structure or change the detection position in a portable manner, the gas in the airbag 1 can be discharged to keep the volume small, which is convenient for the structure to be carried.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
