The edge of the nozzle 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 the chain link of the conveying belt 51, and after the liquid collecting pipe 2 is placed on each bracket 55, a structure that the conveying belt 51 is connected with a plurality of liquid collecting pipes 2 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 connecting frame 35, a driving motor 31, a sealing plate 33, a driving wheel 32 and a sheave 34. A plurality of embedded grooves 341 are annularly distributed on the grooved wheel 34, a convex embedded pin 321 is arranged on the eccentric position of the driving wheel 32, and the closing plate 33 is of a fan-shaped structure. The connecting frame 35 is fixed to the hull 1, the sealing plate 33, the driving wheel 32 and the sheave 34 are all disposed 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 sheave 34 to rotate.
With continued reference to fig. 10 to 13, the grooved pulley 34 is fixed to one of the transmission shafts 52 such that the insertion grooves 341 are annularly distributed around the transmission 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, so that the sealing plate 33 is positioned below the water outlet plane of the water outlet pipe 42, and the sealing plate 33 and the embedded pin 321 are positioned in two opposite directions relative to the output shaft of the driving motor 31. In addition, the outlet pipe 42 is further connected to the connecting frame 35, so that the sealing plate 33 can be rotated to seal the outlet of the outlet pipe 42, and the connecting frame 35 is provided with a through hole 351 at a position corresponding to the outlet of the outlet pipe 42, so that the water in the outlet pipe 42 can flow downwards into the liquid collecting pipe 2 below the outlet pipe 42 through the through hole 351.
With the above structure, when the driving motor 31 drives the driving wheel 32 and the closing plate 33 to rotate, in the process that the driving wheel 32 rotates until the inserting pin 321 is inserted into the inserting groove 341 of the grooved wheel 34, the inserting pin 321 can be driven to push the grooved wheel 34 to rotate in the inserting groove 341 along with the rotation of the driving wheel 32, and after the driving wheel 32 rotates until the inserting pin 321 is separated from the inserting groove 341, the grooved wheel 34 loses power and cannot rotate, which is equivalent to that the driving shaft 52 can be driven to rotate by the grooved wheel 34 in the process that the driving wheel 32 rotates until the inserting groove 341 is inserted into the inserting groove 341, so as to drive the conveying belt 51 to rotate, further, the distance between two adjacent liquid collecting pipes 2 on the conveying belt 51 is the stroke that the inserting pin 321 enters one inserting groove 341 to rotate the driving wheel 53 to drive the conveying belt 51 to move, the distance is set so that the driving wheel 32 can drive the conveying belt 51 to move to drive one liquid collecting pipe 2 to move below the water outlet pipe 42 through the embedded pin 321 every time the driving wheel rotates one circle.
When the driving wheel 32 rotates until the inserting pin 321 is inserted into the inserting groove 341 of the grooved wheel 34, the sealing plate 33 rotates to seal the water outlet of the water outlet pipe 42. As shown in fig. 11, when the inserting pin 321 is rotated to be inserted into one of the inserting grooves 341, the sealing plate 33 rotates toward the direction to seal the water outlet of the water outlet pipe 42; as shown in fig. 12, when the inserting pin 321 is rotated to be inserted into the inserting groove 341 to rotate the grooved pulley 34, the sealing plate 33 seals the water outlet of the water outlet pipe 42; as shown in fig. 13, when the inserting pin 321 is rotated to be separated from the inserting groove 341, the sealing plate 33 is rotated to be separated from the lower side of the water outlet pipe 42. It can be seen that when the sheave wheel 34 rotates, the sealing plate 33 is in a state of sealing the water outlet of the water outlet pipe 42, and when the sheave wheel 34 stops rotating, the sealing plate 33 does not seal the water outlet of the water outlet pipe 42. That is, when the sheave wheel 34 drives the conveyor belt 51 to operate and move the liquid collecting pipe 2, the liquid collecting pipe 2 is not arranged below 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 downwards, the seeped water is prevented from permeating into the hull 1, and the weight of the hull 1 is prevented from being increased due to the excessive seeped water; 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 water pumped by the water pump 41 can flow downwards into the liquid collecting pipe 2, so as to detect the water body of the recirculating aquaculture system.
Preferably, as shown in fig. 6, a water tank 4 is further 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 to the water tank 4. In the working process, when the ship body 1 moves on the water surface of the culture system, the water pump 41 pumps water of a 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 the process, the water tank 4 can form a transition space for temporarily storing water samples, so that when the water outlet of the water outlet pipe 42 is sealed by the water pump 33, the water pump 41 still pumps water to cause overlarge water pressure in the water pump 41 and the water outlet pipe 42, and the service life of the water pump 41 is prevented from being influenced. Further, a drain pipe 45 may be further provided above the water tank 4, the drain pipe 45 extending to the outside of the hull 1, and if the water level in the water tank 4 rises to the drain pipe 45, the excess water may be discharged from the drain pipe 45.
As shown in fig. 8 and 9, a spring 43 is further fixed on the end of the water outlet pipe 42 close to the water outlet, a sealing ring 44 is fixedly connected to the spring 43 at a position below the water outlet, and the elastic force of the extension of the spring 43 pushes the sealing ring 44 downwards, so that a gap is formed between the sealing ring 44 and the nozzle of the water outlet pipe 42. The sealing ring 44 is preferably made of rubber, and the bottom outer edge of the sealing ring 44 is further provided with a chamfer structure, and the chamfer structure forms a guide inclined surface 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, and pushes the sealing ring 44 to move upwards, so that the sealing plate 33 pushes the sealing ring 44 upwards to seal the edge of the water outlet pipe 42. The sealing ring 44 can effectively seal the gap between the sealing plate 33 and the water outlet of the water outlet pipe 42, and prevent water from flowing out. Meanwhile, the smaller gap is needed between the two water outlets of the water outlet pipe 42 sealed by the sealing plate 33, and the designed small gap may cause the sealing plate 33 to be clamped at the edge of the water outlet pipe 42 and not move when rotating to the water outlet pipe 42, and may cause the driving motor 31 to be clamped and not rotate seriously, so that the driving motor 31 is burnt out. Therefore, the spring 43 and the sealing ring 44 are configured to form a certain buffering gap, so as to prevent the sealing plate 33 from being blocked by the bottom side of the water outlet pipe 42.
As shown in fig. 1 and 2, a fixing plate 11 is further fixed on the hull 1. As shown in fig. 7, the fixing manner of the fixing plate 11 may be that a fixing column 12 is fixed on the hull 1, a recessed threaded hole 121 is formed in an upper end surface of the fixing column 12, the threaded hole is in threaded connection with a fixing bolt 13, and a fixing hole 111 is formed in the fixing plate 11. When the fixing plate 11 is installed, the fixing bolt 13 is threaded and fastened with the threaded 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 on the fixing post 12. And the height of the fixing column 12 is slightly higher than the nozzle of the liquid collecting pipe 2 placed on the bracket 55, so that the fixing plate 11 can seal the nozzle of each liquid collecting pipe 2, and simultaneously the liquid collecting pipe 2 is limited on the placing ring 551 of the bracket 55, and the liquid collecting pipe 2 is prevented from falling off due to the shaking of the ship body 1. In addition, a position-giving opening 112 is further formed in one end of the fixing plate 11, and after the fixing plate 11 is fixed to the fixing column 12 of the ship body 1, the position-giving opening 112 is clamped outside the connecting frame 35 in a matched mode. This structure makes the fixed plate 11 can realize taking out vertically upwards when dismantling to be convenient for place of collector tube 2, and when installing then can place vertically downwards when fixed plate 11, convenience very.

During detection, the liquid collecting tube 2 can be taken out of the bracket 55, the detection probe 75 is extended into the liquid collecting tube 2 to contact with a water sample, the detection probe 75 detects the water sample in the liquid collecting tube 2, and then a detection result is displayed through the display screen 72.
Example 2, as shown in fig. 15, the water quality detecting apparatus may be fixed to the bottom inside the header pipe 2, wherein the display screen 72 is embedded in the surface of the header pipe 2, and the detection probe 75 vertically extends upward into the header pipe 2 to directly contact the water sample. The structure of the water quality detection device installed in each liquid collecting pipe 2 can enable the water quality detection device to directly detect water samples, is more convenient, and can more visually observe the detection conditions of the water samples in each liquid collecting pipe 2 so as to facilitate comparison.
In addition, the present invention may further include a control system, which may be a single chip controller, for controlling the operations of the driving motor 31 and the water pump 41, and controlling the movement of the hull 1, specifically, the detection method of the present invention includes the following steps:
placing the ship body on a water body of a circulating water culture system to move, starting the driving motor 31 and the water pump 41, enabling the driving motor 31 to drive the driving wheel 32 and the sealing plate 33 to rotate, and pumping water in the water body to the water outlet pipe 42 by the water pump 41;
when the driving wheel 32 rotates to the position where the embedding pin 321 is to be embedded into one of the embedding grooves 341, the sealing plate 33 rotates towards the direction where the water outlet of the water outlet pipe 42 is to be sealed, 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 inserting pin 321 is rotated to be inserted into the inserting groove 341 to push the grooved pulley 34 to rotate, the sealing plate 33 seals the water outlet of the water outlet pipe 42, and at this time, the grooved pulley 34 rotates to drive the conveying belt 51 to rotate, 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 at this time, the sheave 34 loses the power pushed by the embedded pin 321 and cannot rotate, so that the water collecting pipe 2 is fixed below the water outlet pipe 42, and a water sample pumped by the water pump 41 can flow downwards into the water collecting pipe 2, so as to complete water sample collection of the water collecting pipe 2;
after the driving mechanism 3 is driven to drive the conveying belt 51 to run to each liquid collecting pipe 2 and water samples are collected, the ship body 1 is withdrawn, and the water samples collected in each liquid collecting pipe 2 can be detected through the water quality detection device. It should be noted that, each time the driving wheel 32 makes one turn, the embedded pin 321 may drive the conveying belt 51 to move to drive one liquid collecting tube 2 to move to the lower portion of the water outlet pipe 42 for collecting water samples, so that the time for completing the water sample collection of all the liquid collecting tubes 2 can be determined according to the number of the liquid collecting tubes 2 on the ship body 1, and after the time, the ship body 1 may be retracted, and the retracting manner may be that a hauling rope (not shown in the drawings) is configured on the ship body 1, the ship body 1 is pulled back by pulling the hauling rope, or the ship body 1 is controlled and driven to turn by a remote control system so as to realize that the ship body 1 automatically drives back to the original position.
In summary, the driving mechanism 3 drives the liquid collecting tube 2 to move, and the opening and closing of the water outlet tube 42 can be controlled. Specifically, when the sheave wheel 34 stops rotating, the conveyor belt stops running, so that the liquid collecting pipe 2 stops below the water outlet pipe 42, and at this time, the sealing plate 33 does not seal the water outlet of the water outlet pipe 42, so that the water pumped by the water pump 41 can flow downwards into the liquid collecting pipe 2, and the collection of the water sample by the liquid collecting pipe 2 is completed; when the driving wheel 32 drives the grooved pulley 34 to rotate, the grooved pulley 34 drives the conveying belt 51 to rotate at the same time to move the liquid collecting pipe 2, and at this time, 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 pouring onto the ship body 1, accumulated water can be prevented from permeating into the ship body 1, and the weight of the ship body 1 can be prevented from being increased due to excessive accumulated water. In addition, the conveying belt 51 is driven to move by the structure of the driving mechanism 3, so that the liquid collecting pipe 2 is driven to move to the water outlet pipe 42 and then to pause moving, compared with a mode of collecting water samples by an induction device, the mode of collecting the water samples can effectively reduce the failure rate, and the phenomenon that the ship body 1 returns without work after collecting the water samples on the water surface of the recirculating aquaculture system can be avoided.
