According to the connecting structure, two driving wheels 53 are connected to the hull 1, and the conveying belt 51 is connected to the two driving wheels 53, so that the driving wheels 53 drive the conveying belt 51 to operate through rotation. Further, the driving wheel 53 may be a sprocket, the conveying belt 51 may be a chain, the conveying belt 51 is engaged with two driving wheels 53, and when the driving mechanism 3 drives one driving wheel 53 to rotate, the conveying belt 51 may be driven to rotate, and the other driving wheel 53 may be driven to rotate.
Referring again to fig. 4 and 5, the delivery mechanism further includes brackets 55, each bracket 55 being adapted to receive the header 2. One end of the bracket 55 is a connecting portion 552, and the other end of the bracket 55 is a placement ring 551. The connection portion 552 may be fixed to the conveyor belt 51, specifically, to a link of the conveyor belt 51 by riveting or direct welding, and a plurality of the brackets 55 are fixed to the conveyor belt 51 at equal intervals. The edge of the pipe orifice of the liquid collecting pipe 2 is bent outwards to form a limiting part 21, after the liquid collecting pipe 2 is placed into the placing ring 551 from top to bottom, the placing ring 551 blocks the limiting part 21, so that the placing ring 551 can support the limiting part 21, the liquid collecting pipe 2 is connected to a chain link of the conveying belt 51, after the liquid collecting pipe 2 is placed on each bracket 55, a structure of connecting a plurality of liquid collecting pipes 2 on the conveying belt 51 at equal intervals can be formed, and the liquid collecting pipes 2 can be sequentially conveyed to the position below the water outlet pipe 42 along with the operation of the conveying belt 51.
As shown in fig. 10 to 13, the driving mechanism includes a link 35, a driving motor 31, a sealing plate 33, a driving wheel 32, and a sheave 34. The grooved wheels 34 are annularly distributed with a plurality of embedded grooves 341, the driving wheel 32 is provided with a convex embedded pin 321 at an eccentric position, and the sealing plate 33 is in a fan-shaped structure. The connecting frame 35 is fixed to the hull 1, the sealing plate 33, the driving wheel 32 and the grooved wheel 34 are all arranged in the connecting frame 35, and the driving motor 31 is fixed to the connecting frame 35 to drive the driving wheel 32 and the grooved wheel 34 to rotate.
With continued reference to fig. 10-13, the sheave 34 is fixed to one of the drive shafts 52 such that each of the insert grooves 341 is annularly distributed about the drive shaft 52. The output shaft of the driving motor 31 is fixedly connected with a driving shaft 36, the driving shaft 36 penetrates into the connecting frame 35, the sealing plate 33 and the driving wheel 32 are fixed on the driving shaft 36 from top to bottom, the sealing plate 33 is located below the water outlet plane of the water outlet pipe 42, and the sealing plate 33 and the embedded pin 321 are located in opposite directions relative to the output shaft of the driving motor 31. In addition, the water outlet pipe 42 is further connected to the inside of the connecting frame 35, so that the sealing plate 33 can rotate to seal the water outlet of the water outlet pipe 42, and meanwhile, the connecting frame 35 is provided with a through hole 351 at a position corresponding to the water outlet of the water outlet pipe 42, so that the water of the water outlet pipe 42 can flow downwards into the liquid collecting pipe 2 below the water outlet pipe 42 through the through hole 351.
After the above structure is adopted, when the driving motor 31 drives the driving wheel 32 and the sealing plate 33 to rotate, in the process that the driving wheel 32 rotates until the embedded pin 321 is embedded in the embedded groove 341 of the grooved wheel 34, the embedded pin 321 can be driven to push the grooved wheel 34 to rotate in the embedded groove 341 along with the rotation of the driving wheel 32, and after the driving wheel 32 rotates until the embedded pin 321 is separated from the embedded groove 341, the grooved wheel 34 cannot rotate due to the loss of power, which is equivalent to the fact that the driving wheel 32 can drive the transmission shaft 52 to rotate through the grooved wheel 34 in the process that the driving wheel 32 rotates until the embedded groove 341 is embedded in the embedded groove 341, so as to drive the conveyer belt 51 to operate, and further, the distance between two adjacent liquid collecting pipes 2 on the conveyer belt 51 is the stroke that the embedded pin 321 enters into one embedded groove 341 to enable the driving wheel 53 to rotate so as to drive the conveyer belt 51 to move, and the interval is set so that the driving wheel 32 can drive the conveyer belt 51 to move to the water outlet pipe 42 below the conveyer belt 51 through the embedded pin 321.
When the driving wheel 32 rotates until the insert pin 321 is inserted into the insert groove 341 of the sheave 34, the sealing plate 33 rotates to seal the water outlet of the water outlet pipe 42. As shown in fig. 11, when the insert pin 321 rotates to be inserted into one of the insert grooves 341, the sealing plate 33 rotates toward the water outlet direction of the water outlet pipe 42; as shown in fig. 12, when the insert pin 321 rotates to insert the insert groove 341 to rotate the sheave 34, the sealing plate 33 seals the water outlet of the water outlet pipe 42; as shown in fig. 13, when the insert pin 321 is rotated to be out of the insert groove 341, the closing plate 33 is rotated to be away from the water outlet of the water outlet pipe 42 below. It can be seen that the sealing plate 33 is in a state of sealing the water outlet of the water outlet pipe 42 when the sheave 34 rotates, and the sealing plate 33 does not seal the water outlet of the water outlet pipe 42 when the sheave 34 stops rotating. That is, when the grooved wheel 34 drives the conveyer belt 51 to move the collector tube 2, the collector tube 2 is not under the water outlet pipe 42, and the water outlet pipe 42 is sealed, so that the water pumped by the water pump 41 cannot fall into the hull 1, the accumulated water can be prevented from penetrating into the hull 1, and the weight of the hull 1 can be prevented from being increased due to excessive accumulated water; and when the grooved wheel 34 drives one of the liquid collecting pipes 2 to move below the water outlet pipe 42, the water outlet of the water outlet pipe 42 is not closed, so that the water pumped by the water pump 41 can flow downwards into the liquid collecting pipe 2, and the water body of the circulating water culture system can be conveniently detected.
Preferably, as shown in fig. 6, a water tank 4 is also fixed on the hull 1, the water pump 41 is fixed in the water tank 4, the water inlet pipe penetrates out of the water tank 4 and extends downwards from the side surface of the hull 1 into the water body, and the water outlet pipe 42 is connected with the water tank 4. In the working process, when the hull 1 moves on the water surface of the cultivation system, the water pump 41 pumps the water of the water body into the water tank 4, and when the liquid level is higher than the water outlet pipe 42, the water flows downwards from the water outlet pipe 42. In this process, the water tank 4 may form a transition space for temporarily storing the water sample, so as to prevent the water pump 41 from still pumping water, which causes excessive water pressure in the water pump 41 and the water outlet pipe 42 to affect the service life of the water pump 41, when the water outlet of the water outlet pipe 42 is sealed by the water tank 33. Further, a drain pipe 45 may be provided above the water tank 4, the drain pipe 45 extending outside the hull 1, and if the water level in the water tank 4 rises to the drain pipe 45, the surplus water may be discharged from the drain pipe 45.
As shown in fig. 8 and 9, a spring 43 is further fixed on the outlet pipe 42 at one end near the water outlet, the spring 43 is fixedly connected with a sealing ring 44 at a position below the water outlet, and the elastic force of the stretching of the spring 43 pushes the sealing ring 44 downwards, so that a gap exists between the sealing ring 44 and the pipe orifice of the outlet pipe 42. The seal ring 44 is preferably made of rubber, and a chamfer structure is further provided on the outer edge of the bottom of the seal ring 44, and the chamfer structure forms a guiding inclined plane 441. When the sealing plate 33 rotates to the sealing ring 44, the edge of the upper surface of the sealing plate 33 moves along the guiding inclined plane of the sealing ring, so as to push the sealing ring 44 to move upwards, so that the sealing plate 33 pushes the sealing ring 44 upwards to seal the water outlet edge of the water outlet pipe 42. The seal ring 44 is configured to effectively seal the gap between the sealing plate 33 and the water outlet of the water outlet pipe 42, so as to prevent water from flowing out. Meanwhile, because the water outlets of the water outlet pipe 42 are required to be sealed by the sealing plate 33, a small gap is required, and when the sealing plate 33 rotates to the water outlet pipe 42, the sealing plate 33 is blocked at the edge of the water outlet pipe 42 and cannot move, and the driving motor 31 is blocked and cannot rotate seriously, so that the driving motor 31 is burnt out. Therefore, the spring 43 and the sealing ring 44 can form a certain buffer gap, so as to prevent the sealing plate 33 from being blocked by the bottom side surface of the water outlet pipe 42.
As shown in fig. 1 and 2, a fixing plate 11 is further fixed to the hull 1. The fixing manner of the fixing plate 11 may be as shown in fig. 7, the hull 1 is fixed with a fixing column 12, the upper end surface of the fixing column 12 is provided with a recessed threaded hole 121, the threaded hole is in threaded connection with a fixing bolt 13, and the fixing plate 11 is provided with a fixing hole 111. When the fixing plate 11 is mounted, the fixing bolt 13 is screwed to be fastened with the screw hole 121 of the fixing post 12 after passing through the fixing hole 111, so that the fixing bolt 13 presses and fixes the fixing plate 11 to the fixing post 12. And the height of the fixing column 12 is slightly higher than the pipe orifice of the liquid collecting pipe 2 placed on the bracket 55, so that the fixing plate 11 can seal the pipe orifice of each liquid collecting pipe 2, and meanwhile, the liquid collecting pipe 2 is limited on the placing ring 551 of the bracket 55, so that the liquid collecting pipe 2 is prevented from falling down due to shaking of the ship body 1. In addition, one end of the fixing plate 11 is further provided with a relief port 112, and after the fixing plate 11 is fixed on the fixing column 12 of the hull 1, the relief port 112 is adapted to be clamped outside the connecting frame 35. This structure makes it possible to achieve vertical upward removal of the fixing plate 11 when detached, thereby facilitating placement of the liquid collecting tube 2, and vertical downward placement when the fixing plate 11 is installed, which is quite convenient.
Preferably, as shown in fig. 14 and 15, the present invention further includes a water quality detecting device including a storage battery 73, a detecting unit 74, a detecting probe 75 and a display screen 72. The display screen 72 and the detection probe 75 are electrically connected to the detection unit 74, the detection probe 75 contacts with the water sample in the liquid collecting tube 2 to detect the water sample, signals are sent to the detection unit 74, and the detection unit 74 processes the signals and sends the processed signals to the display screen 72 for display.

The structure of the water quality detection device is arranged in each liquid collecting pipe 2, so that the water quality detection device can directly detect a water sample, the water quality detection device is more convenient, and the water sample detection condition in each liquid collecting pipe 2 can be more intuitively observed, so that the comparison is convenient.
In addition, the invention may further comprise a control system, which may be a single-chip microcomputer controller, for controlling the operation of the driving motor 31 and the water pump 41, and simultaneously controlling the movement of the hull 1, and specifically, the detection method of the invention comprises the following steps:
The ship body is placed on a water body of a circulating water culture system to move, the driving motor 31 and the water pump 41 are started, the driving motor 31 drives the driving wheel 32 and the sealing plate 33 to rotate, and the water pump 41 pumps water in the water body to the water outlet pipe 42;
When the driving wheel 32 rotates to the position where the embedding pin 321 is about to be embedded into one of the embedding grooves 341, the sealing plate 33 rotates towards the direction of the water outlet pipe 42, and at this time, the water collecting pipe 2 is arranged below the water outlet pipe 42, so that the water sample pumped by the water pump 41 can flow downwards into the water collecting pipe 2;
when the embedding pin 321 rotates to be embedded in the embedding groove 341 to push the grooved wheel 34 to rotate, the sealing plate 33 seals the water outlet of the water outlet pipe 42, and at this time, the grooved wheel 34 rotates to drive the conveying belt 51 to operate, so that the conveying belt 51 conveys the next liquid collecting pipe 2 to the position below the water outlet pipe 42;
when the embedded pin 321 rotates to be separated from the embedded groove 341, the sealing plate 33 rotates to be separated from the lower part of the water outlet pipe 42, and the power of the grooved wheel 34 pushed by the embedded pin 321 is lost, so that the liquid collecting pipe 2 is fixed below the water outlet pipe 42, and the water sample extracted by the water pump 41 can flow downwards into the liquid collecting pipe 2, thereby completing the water sample collection of the liquid collecting pipe 2;
After the driving mechanism 3 drives the conveyer belt 51 to operate until water samples are collected on the liquid collecting pipes 2, the ship body 1 is retracted, and the water samples collected in the liquid collecting pipes 2 can be detected through a water quality detection device. It should be noted that, the driving wheel 32 may drive the conveyer belt 51 to move to drive one of the liquid collecting pipes 2 to move to the lower side of the water outlet pipe 42 through the embedded pin 321 after one turn, so that the time for completing the water sample collection of all the liquid collecting pipes 2 can be determined according to the number of the liquid collecting pipes 2 on the hull 1, and the hull 1 can be retracted after the time, and the retraction mode may be that a traction rope (not shown in the drawing) is configured on the hull 1, the hull 1 is pulled back through the traction rope, or the hull 1 is driven to turn through the control of the remote control system so as to realize the automatic driving of the hull 1.
In summary, the present invention can control the opening and closing of the water outlet pipe 42 while driving the liquid collecting pipe 2 to move by the driving mechanism 3. Specifically, when the sheave 34 stops rotating, the conveyor belt pauses to stop the liquid collecting pipe 2 below the water outlet pipe 42, and the sealing plate 33 does not seal the water outlet of the water outlet pipe 42 at this time, so that the water pumped by the water pump 41 can flow downwards into the liquid collecting pipe 2 to complete the collection of the water sample by the liquid collecting pipe 2; when the driving wheel 32 drives the sheave 34 to rotate, the sheave 34 simultaneously drives the conveyor belt 51 to rotate so as to move the liquid collecting tube 2, and the sealing plate 33 is in a state of sealing the water outlet of the water outlet pipe 42, so that water pumped by the water pump 41 can be prevented from being poured onto the hull 1, seeper into the hull 1 can be prevented, and excessive seeper can be prevented from increasing the weight of the hull 1. In addition, the invention drives the conveyer belt 51 to move through the structure of the driving mechanism 3, drives the liquid collecting pipe 2 to move to the water outlet pipe 42 and then stops moving, and compared with the mode realized through the sensing device, the invention can effectively reduce the failure rate, and can avoid the phenomenon that the ship body 1 returns without work after collecting the water sample on the water surface of the circulating water culture system.
The foregoing is merely illustrative of specific embodiments of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modification of the present invention by using the design concept shall fall within the scope of the present invention.
