Description

Technical Field

[0001] This utility model relates to the field of East Wind Snail farming technology, and in particular to a sampling device for East Wind Snail farming water quality. Background Technology

[0002] Conch farming is a high-efficiency aquaculture model with a short farming cycle and high profits, but it requires meticulous management of water quality, feed and disease prevention. The main farming techniques include pond farming, cage farming and harbor enclosure farming.

[0003] The East Wind Snail is highly sensitive to changes in water quality. The selection of its breeding area is a prerequisite for successful breeding, and water quality management is an important measure in the breeding process. It is necessary to start from multiple parameters such as water temperature, salinity, dissolved oxygen, pH value, ammonia nitrogen and nitrite to ensure that the water quality is stable, clean and suitable, so as to effectively improve the growth rate and survival rate of the East Wind Snail. Therefore, real-time collection of water samples and monitoring of water quality can help ensure breeding benefits and is an indispensable part of modern precision breeding.

[0004] A search revealed that Chinese utility model patent CN218524406U discloses a sampling device for testing water in sea grape aquaculture, comprising a top rod, a connecting rod, a sampling mechanism, and a water flow generating mechanism. The sampling mechanism includes a lifting motor, a lifting rod, a piston, a sampling cylinder, and a water inlet. The connecting rod connects the bottom surface of the top rod to the side wall of the sampling cylinder. The lifting motor is located on the bottom surface of the top rod, and its output shaft is connected to the top of the lifting rod. The bottom end of the lifting rod is connected to the piston, which is located inside the sampling cylinder. The water inlet is located on the bottom surface of the sampling cylinder. This application samples the aquaculture water using negative pressure suction; however, this sampling method has low consistency, and because the sample is obtained from a single location, it is difficult to guarantee that the water sample represents the overall water quality. Utility Model Content

[0005] In view of the above-mentioned prior art, the present invention provides a sampling device for the water quality of conch farming, and the main technical problem to be solved is how to improve the continuity and representativeness of water sampling.

[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows: A sampling device for water quality in the cultivation of Conch robin includes a feed cylinder, which is equipped with a collection mechanism, a drive mechanism, and a spiral blade for sampling. The drive mechanism draws water from the cultivation into the feed cylinder by driving the spiral blade to rotate. The collection mechanism includes a tray for loading sampling containers. The tray is used to adjust the alignment of different sampling containers with the feed cylinder to hold water samples.

[0007] Furthermore, the material cylinder is tilted, and a mesh cylinder is fixedly connected to one side of the lower end of the material cylinder. The material cylinder and the mesh cylinder are rotatably connected by the same central shaft.

[0008] Furthermore, the spiral blades are fixedly connected to the outside of the central shaft, and a bracket is fixedly connected to the bottom of the mesh cylinder, with a ball foot fixedly connected to the bottom of the bracket.

[0009] Furthermore, a housing is fixedly connected to the high end of the barrel, and the drive mechanism includes a motor fixedly connected in the housing, with one end of the motor's output shaft fixedly connected to the central shaft.

[0010] Furthermore, a swing arm is rotatably connected to one side of the bottom of the casing via a damping shaft, a support plate is rotatably connected to the bottom of the swing arm, and a water outlet is provided at the bottom of the high end of the barrel.

[0011] Furthermore, a collar is fitted on the outer side of the housing, and support rods are rotatably connected to both sides of the bottom end of the collar, with rollers rotatably connected to the bottom ends of the two support rods.

[0012] Furthermore, a screw is rotatably connected to the middle of the bottom end of the collar, a knob is fixedly connected to the bottom end of the screw, and a threaded sleeve is threadedly connected to the outer side of the screw.

[0013] Furthermore, connecting rods are rotatably connected between the threaded sleeve and both support rods.

[0014] Furthermore, a water outlet pipe is fixedly connected to the bottom end of the barrel at the water outlet, and the water outlet pipe is made of a metal shaped flexible hose.

[0015] The beneficial effects of this utility model are as follows: 1. This application uses the rotation of the spiral blades to first extract the water used for the cultivation of the conch and then discharge it back. During this process, since the water is continuously flowing, water samples can be collected from different locations in the cultivation pond through multiple samplings to ensure the representativeness of the samples. At the same time, several sampling bottles can be placed on the rotating tray, so sampling can be carried out continuously by rotating the tray, thus ensuring convenient sampling. 2. By setting up threaded rods and support rods, and using the threaded rods to drive the threaded sleeves to move, the connecting rods can be pushed and pulled to deflect the support rods, thereby adjusting the height of the collar and the inclination angle of the material cylinder, so that the device can be adapted to sampling water bodies of different depths for the cultivation of East Wind Snails. 3. By setting up a water outlet pipe made of a metal-shaped flexible tube, the drop point of the aquaculture water after it is drawn out can be adjusted to ensure that it can accurately enter the sampling bottle and avoid splashing that would cause water sample loss.

[0018] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the utility model.

[0019] Example 1 See attached document Figure 1-2 This application provides a sampling device for the water quality of conch aquaculture, including a feed cylinder 1. The feed cylinder 1 is equipped with a collection mechanism, a driving mechanism, and a spiral blade 12 for sampling. The driving mechanism drives the spiral blade 12 to rotate to draw aquaculture water into the feed cylinder 1. The collection mechanism includes a tray 6 for loading sampling containers. The tray 6 is used to adjust the alignment of different sampling containers with the feed cylinder 1 to hold water samples, thus enabling continuous sampling. Since continuous sampling is carried out by rotating the tray 6, it is only necessary to control the rotation speed of the tray 6 to obtain water samples from different flow sections, so as to ensure that the monitoring results of the water samples can reflect the overall water quality of the aquaculture water.

[0020] When using this device to sample water quality for monitoring the culture of Oriental whelks, the lower end of the device can be placed in the culture water, with the swing arm 5 positioned at the edge of the water body. Then, the motor 2 is connected to an external power source and started.

[0021] Preferably, the feed cylinder 1 is tilted, and the feed cylinder 1 and the mesh cylinder 11 are rotatably connected to the same central shaft 13. The spiral blades 12 are fixedly connected to the outside of the central shaft 13. Although this device does not move in the aquaculture water, the continuous operation of the spiral blades 12 allows the water to flow in the feed cylinder 1. Therefore, by collecting water samples from different flow sections, the effect of collecting water samples from different locations can be achieved.

[0022] The motor 2 drives the spiral blades 12 to rotate through the central shaft 13, thus drawing the aquaculture water into the feed cylinder 1 and conveying it from bottom to top to the outlet for discharge, and then it flows back to the aquaculture pond, thereby allowing the aquaculture water to flow in the feed cylinder 1.

[0023] Preferably, a swing arm 5 is rotatably connected to one side of the bottom of the housing 4 via a damping shaft, and a tray 6 is rotatably connected to the bottom of the swing arm 5. A water outlet is provided at the bottom of the high end of the material cylinder 1. The swing arm 5 can be used to adjust the deflection of the tray 6 so that the tray 6 can be stored when no sample is being taken, thus avoiding continuous splashing of water due to water flow impacting the tray 6 and causing water sample waste.

[0024] Once the device is operational, several sampling bottles can be placed on the tray 6. By rotating the tray 6, the sampling bottles can be aligned with the water outlet in sequence to obtain the aquaculture water in a flowing state. By simply slowing down the rotation speed of the tray 6, different sampling bottles can collect water from different locations to ensure the representativeness of the water samples.

[0025] Preferably, a net cylinder 11 is fixedly connected to one of the lower ends of the feed cylinder 1, a bracket 10 is fixedly connected to the bottom end of the net cylinder 11, and a ball foot 9 is fixedly connected to the bottom end of the bracket 10. The ball foot 9 can still provide support for the bottom end of the feed cylinder 1 when it is deflected and adjusted, so as to ensure the stability of the feed cylinder 1. In addition, the bracket 10 is triangular, so it can ensure the stability between the ball foot 9 and the feed cylinder 1.

[0026] In addition, the presence of the net tube 11 can separate the spiral blades 12 while ensuring water permeability, so as to prevent the continuous rotation of the spiral blades 12 from accidentally injuring the snails and affecting the aquaculture benefits.

[0027] Preferably, a collar 3 is fitted onto the outer side of the housing 4. Support rods 7 are rotatably connected to both sides of the bottom end of the collar 3, and rollers 8 are rotatably connected to the bottom ends of both support rods 7. A screw 14 is rotatably connected to the middle of the bottom end of the collar 3. A knob 16 is fixedly connected to the bottom end of the screw 14, and a threaded sleeve 17 is threadedly connected to the outer side of the screw 14. A connecting rod 15 is rotatably connected between the threaded sleeve 17 and both support rods 7.

[0028] When there are aquaculture water bodies of different depths, the upper end of the feed cylinder 1 can be raised, with the roller 8 suspended in the air. The knob 16 can be turned, and the knob 16 can drive the screw 14 to rotate, which can cause the threaded sleeve 17 to move in the vertical direction. The movement of the threaded sleeve 17 can push and pull the support rod 7 through the connecting rod 15 to produce deflection. By deflecting the two support rods 7, the height of the collar 3 can be changed. Therefore, after the feed cylinder 1 is lowered and placed back on the ground, the tilt angle of the feed cylinder 1 will also change. Thus, by turning the knob 16, the upward and downward tilt of the feed cylinder 1 can be adjusted to adapt to aquaculture water bodies of different depths.

[0029] Example 2 See attached document Figure 3 This application provides a sampling device for the water quality of conch farming. Compared with embodiment 1, in order to ensure accurate sampling, a water outlet pipe 18 is fixedly connected to the bottom end of the feed cylinder 1 at the water outlet. The water outlet pipe 18 is made of a metal shaped flexible tube.

[0030] When placing the sampling bottle on the tray 6 to collect water samples, the water outlet pipe 18, made of a metal shaped flexible tube, can be bent to accurately align it with the sampling bottle, thereby ensuring that the water can flow accurately into the sampling bottle and avoiding splashing that could lead to water sample loss.

[0031] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model shall be determined by the protection scope of the claims.
