Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-3 and Figure 6An environmental monitoring device includes a sampling bottle 10, the sampling bottle 10 is arranged on a sampling mechanism, the sampling mechanism includes a vertical driving module and a horizontal driving module, the vertical driving module is used to control the sampling bottle 10 to move in the vertical direction below the water surface, a leaf door 14 is rotatably connected inside the sampling bottle 10, and the horizontal driving module is used to drive the leaf door 14 to rotate inside the sampling bottle 10. When the leaf door 14 rotates inside the sampling bottle 10, the sampling bottle 10 can be controlled to switch back and forth between an open state and a closed state. When the horizontal driving module does not operate the leaf door 14, the leaf door 14 is in a closed state with the sampling bottle 10 in a natural state. When the vertical driving module controls the sampling bottle 10 to move downward and the horizontal driving module operates the sampling bottle 10, the leaf door 14 rotates and the sampling bottle 10 opens, so that the sampling bottle 10 can quickly collect water quality samples located in different water layers, which is convenient for subsequent monitoring and processing of water quality.

[0024] The vertical drive module includes three groups of drive units, each group of drive units includes a top plate 1, a motor 2, a base 3, a sleeve 4, a threaded sleeve 5 and a screw 6. A slide rod 32 is fixedly connected between the top plate 1 and the base 3, and the sleeve 4 is slidably sleeved on the slide rod 32. A screw 6 is also rotatably connected between the top plate 1 and the base 3. The screw 6 is fixedly connected to the output end of the motor 2, and the motor 2 is installed on the top plate 1. The threaded sleeve 5 and the screw 6 are threadedly connected. As shown in the figure, in order to improve the stability during implementation, the screw 6 is placed between the two slide rods 32. At the same time, the three groups of drive units are evenly arranged on the base 3. The sleeve 4 and the threaded sleeve 5 are movably connected. The sleeve 4 drives the horizontal drive module to operate through a connecting rod assembly.

[0025] The connecting rod assembly includes a first rotating rod 7, a second rotating rod 8 and a connecting disk 12. The first rotating rod 7 is rotatably connected to the sliding sleeve 4. The first rotating rod 7 is rotatably connected to the connecting disk 12 through the second rotating rod 8. The connecting disk 12 is located at the center of the three groups of driving units, and a horizontal driving module is arranged on one side of the connecting disk 12.

[0026] The horizontal driving module includes a driving nail 30, a slide rail 13, a resistance block 17, a vortex rod 18 and a fixing nail 19. The driving nail 30 is elastically connected to the connecting disk 12. A connecting plate 16 is arranged directly below the connecting disk 12. A plurality of slide rails 13 are evenly arranged on the connecting plate 16. The number of the slide rails 13 corresponds to the number of the driving units. In the present embodiment, the number of the slide rails 13 is three. The slide rails 13 are elastically slidably connected with the resistance block 17. The resistance block 17 is located on the moving stroke of the driving nail 30. The fixing nail 19 is fixedly connected to the resistance block 17. When the three motors 2 in the vertical driving module rotate asynchronously, the connecting disk 12 will be deflected under the action of the connecting rod assembly. The deflection trajectory is an arc. When the driving nail 30 hits the resistance block 17, the resistance block 17 will drive the fixing nail 19 to move. At the same time, the fixing nail 19 originally located in the vortex rod 18 drives the vortex rod 18 to rotate while making a linear movement, thereby opening the fan door 14, so that the external water flow can enter the sampling bottle 10, and the sampling bottles 10 corresponding in number to the slide rail 13 are fixedly connected below the connecting plate 16, and the sampling bottles 10 are rotatably connected with the fan door 14 through the vortex rod 18, and the vortex rod 18 is located on the moving stroke of the fixing nail 19, and the fan door 14 and the sampling bottle 10 are connected by a coil spring. After the sample is collected, the motor 2 is driven to operate, so that the sliding sleeve 4 in each group of driving units moves to the same horizontal plane, and the driving nail 30 and the resistance block 17 are separated. Under the action of the elastic force, the resistance block 17 brings the fixing nail 19 back to the vortex rod 18, and the fan door 14 is closed with the sampling bottle 10 again, completing the purpose of collecting water quality samples.

[0027] The door 14 is fixedly connected with a gear 27, and the sampling bottle 10 is rotatably connected with a gear 28. The gear 27 and the gear 28 are meshed and transmitted. A rotating cylinder 29 is fixedly connected to the upper part of the gear 28, and a plurality of barbs are fixedly connected to the rotating cylinder 29. The barbs can be used to collect water plants in the water during the opening of the sampling bottle 10 and the door 14. The barbs play a role of winding up during the rotation of the door 14 and the sampling bottle 10. When the door 14 and the sampling bottle 10 are closed, the water plants will be cut off by the sampling bottle 10 and the door 14, or in other words, after the door 14 and the sampling bottle 10 clamp the water plants, the water plants will be pulled off during the rising process of the sampling bottle 10. The type of water plants is also an indispensable factor for analyzing water quality.

[0028] Embodiment 2

[0029] See also Figure 1 , Figure 4 and Figure 5On the basis of the above embodiment, the sliding sleeve 4 and the threaded sleeve 5 below the top plate 1 are magnetically attracted to each other, a stop block 20 is fixedly connected to the sliding rod 32, a piston rod 21 is sleeved on the screw rod 6, and a piston plate 31 is fixedly connected to one end of the piston rod 21 passing through the base 3. The piston plate 31 is fitted and slidably connected to the first column 22 located in the base 3. When the screw rod 6 drives the sliding sleeve 4 and the threaded sleeve 5 to move downward continuously, the sliding sleeve 4 and the stop block 20 conflict with each other because of the continuous rotation of the screw rod 6, which makes the sliding sleeve 4 and the threaded sleeve 5 overcome the magnetic force, so that the threaded sleeve 5 continues to move downward. A second column 23 is also provided in the base 3, and the second column 2 3 is provided with a connecting shaft 24, which is connected to the sampling bottle 10 through the chassis 15, one end of the connecting shaft 24 is fixedly connected to the chassis 15 and the other end is elastically connected to the second column 23, a storage cavity is provided in the second column 23, one side of the storage cavity is fixedly connected to an elastic capsule 26, the purpose of the elastic capsule 26 is to controllably adjust the size of the space in the storage cavity under the action of air pressure, so that the biological sand in the storage cavity can be pressed into the first column 22 to the maximum extent, the storage cavity is connected to the first column 22 through the first pipe, the first column 22 is connected to the outside through the second pipe, and a one-way valve is installed in the first pipe and the second pipe. The gas in the first column 22 is gradually squeezed by the piston rod 21, so that the space in the first column 22 is compressed, and then under the action of the two one-way valves, the biological sand in the storage cavity is sprayed into the water, thereby achieving the purpose of controllable rapid artificial water purification, and the piston plate 31 is used to compress the air in the first column 22.

[0030] Biological sand is cultivated through screening with dozens of culture media. Biological sand is in a state of growth and reproduction for a long time, becoming a natural biological filter bed under the pond. The microorganisms attached to the surface of the sand can effectively decompose the leftover bait, fish feces and other decaying materials in the water, forming gaseous substances such as nitrogen dioxide, hydrogen sulfide and nitrogen that are discharged into the water body, automatically purifying the water body. The selected bacteria are beneficial to fish and can promote fish growth.

[0031] The top plate 1 is provided with a feed hole 11, which is connected to the storage chamber through a connecting pipe 25. The biosand can be injected into the feed hole 11 at an appropriate time to achieve the purpose of rapid filling of the biosand. It is known that the feed hole 11 can be sealed with a plug or the like when necessary.

[0032] The connecting disk 12 below the top plate 1 is rotatably connected with the fan blade 9. By reasonably controlling the rotation speed of the motor 2, the connecting disk 12 drives the fan blade 9 in the process of rising or falling, so that the fan blade 9 and the water flow interact with each other. The rotation speed of the fan blade 9 is related to the speed of its movement, so as to realize the rotation of the fan blade 9. When the fan blade 9 rotates, the biological sand ejected from the first column 22 can be driven to a farther water area, thereby improving the water purification ability of the design.
