Example 1:
as shown in figure 1, the invention provides a water quality detection device for inland lakes, which comprises a suspension detection platform 1 and a separation sampling structure 2 arranged on the suspension detection platform 1, wherein the separation sampling structure 2 is used for sampling after isolating aquatic plants;
the separation sampling structure 2 comprises an external expansion type separation device 201 arranged on the water body contact surface of the suspension detection platform 1 and a built-in sampling component 202 arranged in the external expansion type separation device 201, the external expansion type separation device 201 increases an internal sampling space through an external expansion mode to separate aquatic plants from the outside, and the built-in sampling component 202 removes limitation when the internal space of the external expansion type separation device 201 is expanded and performs static sampling after adapting to the water body flow direction.
When the device is used, the suspension detection platform 1 is used for providing a fixed sampling position for the separation sampling structure 2, maintaining the operation stability of the separation sampling device 2, and meanwhile, a simple device for automatically detecting a water body sample can be arranged, such as a sensor for detecting the water quality of a water body.
The separation sampling structure 2 is used for amplifying the internal sampling space through the external expansion type separation device 201 when a water body is sampled, and separating and driving the aquatic plants away from the built-in sampling component 202 while amplifying the internal sampling space, so that the problem that the aquatic plants are wound to block the built-in sampling component to influence water and soil sampling and normal water quality detection is avoided.
Meanwhile, the internal sampling space amplification avoids the interference of taking samples by the built-in sampling component 202, ensures the normal collection of water body samples, and reduces the disturbance to water body components by adapting to the horizontal flow direction to influence the accuracy of detection results.
After the sample collection is completed, the external expansion type separation device 201 is reset, the built-in sampling component 202 can be coated and limited again, the aquatic plants are prevented from being wound and attached, the aquatic plants attached to the surface can be torn through the external expansion of the external expansion type separation device 201, and the interference of the aquatic plants is further avoided.

the right-angle sides of the four right-angle external expansion plates 205 form a square space together, the built-in sampling component 202 is arranged in the square space and connected with the external expansion connecting plate 203, each right-angle external expansion plate 205 moves along the diagonal of the horizontal section of the square space through the cross external expansion structure 204 to expand the internal volume, and the telescopic separation net 206 adapts to the size change of the square space 206 to limit aquatic plants from entering the square space.
When the external expansion type separation device 201 is used, the right-angle sides of the plurality of right-angle external expansion plates 205 jointly form a square space, namely, a sampling space, and the square space is wrapped by the built-in sampling component 202 to limit the external aquatic plants to enter and climb, so that the influence on water sampling is avoided.
The cross-shaped external expansion structure 204 drives the plurality of right-angle external expansion plates 205 to move along the diagonal direction of the horizontal section of the square space, a gap is formed between every two adjacent right-angle external expansion plates 205 and is blocked by the telescopic separation net 206, so that aquatic plants are limited from entering the square space, and the problem that the built-in sampling part 202 is blocked by the aquatic plants in the sampling process in the square space is solved.
Secondly, the square space formed by the right-angle external expansion plate 205 protects the built-in sampling component 202, and the problem that the built-in sampling component 202 cannot be blocked due to aquatic plants climbing when the built-in sampling component is not used is avoided.
The cross outward-expanding structure 204 comprises two first linear grooves 207 arranged on the outward-expanding connecting plate 203 in parallel and a first bidirectional screw 208 arranged in the first linear grooves 207, two middle connecting plates 209 connected with the outward-expanding connecting plate 203 in a sliding manner are arranged on the two first bidirectional screws 208 by taking a midpoint position connection line as a symmetry center, two second linear grooves 210 are arranged on the middle connecting plates 209 along a direction perpendicular to the axis of the first bidirectional screw 208, a second bidirectional screw 211 connected with a corresponding right-angle outward-expanding plate 205 is arranged in each second linear groove 210, and the right-angle outward-expanding plates 205 expand the volume of a square space under the common driving of the first bidirectional screw 208 and the second bidirectional screw 211 to separate aquatic plants from the built-in sampling part 202.
When the cross-shaped external expansion structure 204 drives the right-angle external expansion plate 205 to move, the two first bidirectional screws 208 and the two second bidirectional screws 211 are driven to rotate simultaneously by the driving device, the first bidirectional screws 208 drive the two middle connecting plates 209 to move back to back at the same speed, and the second bidirectional screws 211 drive the two corresponding right-angles external expansion plates 205 to move back to back, so that the right-angle external expansion plate 205 moves along two mutually-perpendicular directions simultaneously, and the combined movement direction is along the diagonal direction of the horizontal section of the square space.
Gaps are reserved between the right-angle outer expansion plates 205 moving along the diagonal direction for water to pass through, and meanwhile, the aquatic plants are isolated to the outside of the square space by the telescopic separation net 206, so that interference of the aquatic plants on the built-in sampling components 205 is avoided.
Secondly, the first linear groove 207 and the second linear groove 210 are used for placing and installing the first bidirectional screw 208 and the second bidirectional screw 211, and the interference of the first bidirectional screw 208 and the second bidirectional screw 211 on the installation position of the built-in sampling component 202 is avoided.
The outer wall of the right-angle expanding plate 205, which deviates from the center of the square space, is provided with a reinforcing rib 212 which is in sliding connection with the expanding connecting plate 203, and the sliding track of the reinforcing rib 212 is the same as the motion track of the right-angle expanding plate 205.
Because the right-angle outward-expanding plate 205 goes deep into the water body and is driven to reciprocate by the cross outward-expanding structure 204, water flow greatly hinders the right-angle outward-expanding plate 205, so that the right-angle outward-expanding plate 205 is poor in stability, the loads of the first bidirectional screw 208 and the second bidirectional screw 211 are large and easy to damage, and the reinforcing rib 212 is arranged to assist in supporting the right-angle outward-expanding plate 205, so that the stability of the right-angle outward-expanding plate 205 in the moving process is improved.
The telescopic separation net 206 comprises a winding groove 213 which is arranged on the contact surface of the right-angle outward expansion plate 205 and the adjacent right-angle outward expansion plate 205 along the vertical direction and a winding roller 214 which is arranged in the winding groove 213 through a torsion spring, the winding roller 214 is wound with a separation net 215 which is connected with one side of the corresponding right-angle outward expansion plate 205 in a winding manner, and the separation net 215 expands the area for separating aquatic plants through the movement release of the right-angle outward expansion plate 205 and is automatically wound through the torsion spring.
The telescopic separation net 206 is used to separate aquatic plants to the outside of the square space.
When the right-angle expanding plate 205 expands the internal sampling space, the right-angle expanding plate 206 pulls the corresponding isolation net 215 to move synchronously, and the isolation net 215 is released synchronously through the take-up roller 214 to ensure the isolation of the sampling space.
The isolation net 215 is kept tight under the elastic force action of the torsion spring, and the problem that the isolation net 215 is contacted with the built-in sampling component 202 due to looseness and is further contacted with the built-in sampling component 202 to cause blockage is avoided.
Secondly, through the elastic force of the torsion spring, when the plurality of right-angle outer expanding plates 205 are reset, the isolation net 215 is reeled on the reeling roller 214 again under the elastic force, so as to avoid the interference of resetting the right-angle outer expanding plates 205 and ensure the coating protection of the built-in sampling component 202 when the sampling component is not in use.
A plurality of spurs 216 are arranged at the notch of the winding groove 213 at equal intervals along the length direction, a plurality of thorn-shaped protrusions 217 are arranged on the surface of each spur 216, and the plurality of spurs 216 scrape off the attached aquatic plants when the separation net 215 is reset and carry out auxiliary adhesion removal through the thorn-shaped protrusions 217.
Considering that the separation net 215 has the problem of aquatic plants climbing in the using process, the synchronous motion in the winding process of the separation net 215 causes the blockage faults of the winding groove 213 and the winding roller 214, the burs 216 are arranged at the notches of the winding groove 213, the aquatic plants are scraped and cleaned through the burs when entering the winding groove 213, meanwhile, the scraping effect on the aquatic plants is increased through the bur-shaped protrusions 217 on the burs 216, and the cleaning effect on the aquatic plants is further improved.
Furthermore, the burs 216 may be made of an elastic material and have a certain elastic deformation capability, so that the burs 216 may directly contact with the separation net 215, and the burs 216 may be deformed by interference between the separation net 215 and the burs 216, and the burs 216 may clean the aquatic plants on the separation net 215 by the elastic force generated by the deformation, thereby improving the cleaning effect.
The built-in sampling component 202 comprises two strip-shaped plates 218 which are arranged on the outer expansion connecting plate 203 in parallel along the vertical direction and a plurality of sampling connecting plates 219 which are arranged between the two strip-shaped plates 218 at equal intervals along the vertical direction, one side, far away from the outer expansion connecting plate 203, of each sampling connecting plate 219 is provided with a sampling connecting rod 220 along the vertical direction, the end part of each sampling connecting rod 220 is movably connected with an adaptive sampling port 221, and the adaptive sampling port 221 is used for extracting a water flow sample through a pump body after adapting to the water flow direction for detection.
When the built-in sampling component 202 samples the water body, the sampling depth is determined, after the external expansion type separation device 201 completes the amplification of the sampling space, the position is adjusted by the adaptive sampling port 221 under the action of the flow direction of the water body, and then the water body sample is extracted through the pump body.
Through the adaptation between adaptive sampling mouth 221 and the water flow direction, reduce the interference to rivers before the sample, avoid the change of water composition and content in the sample space part, promote the accuracy of testing result.
Secondly, a plurality of adaptability sample connection 221 that equidistant setting can take a sample by the water of many different degree of depth, has enlarged the scope of water sample, can carry out water quality testing to the water of the different degree of depth, has further promoted water quality testing's accuracy.

wherein, the rotating seat 222 is connected to the outer wall of the sampling tube 223 at a position close to the end, and the connecting position of the rotating seat 224 and the sampling tube 223 is far away from the concave arc-shaped wall 224.
When the adaptive sampling port 221 is used, water flow acts on the concave arc-shaped wall 224, so that the sampling cylinder rotates around the rotating seat 222 until the direction of the sampling cylinder is the same as the direction of the water flow, and the influence on the distribution of components in the water body due to large interference on the water body flow is avoided.

The length of the sampling tube 223 is equal to the width of the strip-shaped plate 218 and the distance between the two strip-shaped plates 218, and the width of the strip-shaped plate 218 is equal to the distance between the inner walls of the two corresponding right-angle outer expanding plates 205.
In the whole sample collecting process, the sampling cylinder 223 should be located in the space formed by the two strip-shaped plates 218 all the time in the adjusting and steering process, so that the problems that the aquatic plant card is arranged in a gap between the two right-angle outer expanding plates 205 due to interference when the right-angle outer expanding plates 205 are reset and the flow direction of water and the distribution of water components when samples are collected are further influenced are avoided, and the length of the sampling cylinder 223 is limited.
