Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically to a sampling device for water quality testing in aquaculture. Background Technology

[0002] Aquaculture generally refers to the cultivation of aquatic animals and plants, such as fish, shrimp, crabs, shellfish, and algae, based on the ecological habits and aquatic environmental requirements of the farmed species, using aquaculture technology and facilities. Water quality control is crucial in aquaculture. Low oxygen levels in the water lead to reduced feeding by fish, and pH levels deviating from the normal range can disrupt cell osmotic pressure, hindering fish growth and increasing the risk of disease. To improve the economic benefits of aquaculture, regular water quality testing is necessary. A common method is for personnel to directly sample from the pond, but the sampling location is not fixed and is affected by oxygen levels and microorganisms at different depths. This sampling method has significant errors and is not conducive to timely adjustments based on water quality changes, thus presenting shortcomings. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a water quality testing and sampling device for aquaculture. It can sample aquaculture water at different depths according to the testing requirements. During the sampling process, the aquaculture water can be reduced to avoid errors in water quality testing caused by changes in oxygen content due to water flow. At the same time, the sampling device can be positioned well during the sampling process, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for water quality testing in aquaculture, comprising a positioning cylinder and a collection box, wherein a sampling box is slidably installed inside the positioning cylinder, a communication port is provided on the side of the positioning cylinder, a sampling port is provided on the side of the sampling box, a connecting pipe is fixedly installed on the upper side of the sampling box, and the upper end of the connecting pipe extends to the outside of the positioning cylinder, the connecting pipe is made of rigid material, and a guide pipe communicating with the inner cavity of the collection box is provided at the end of the connecting pipe, and a positioning component is slidably arranged on the outside of the positioning cylinder.

[0005] As a preferred technical solution of this utility model, the positioning component includes a mounting cylinder sleeved on the outside of the positioning cylinder, a buoyancy plate is fixed on the lower side of the mounting cylinder, and scale lines are provided on the outside of the positioning cylinder along its length.

[0006] As a preferred embodiment of this utility model, a mounting base is fixed to the side of the mounting cylinder, and a positioning screw for positioning the mounting cylinder is provided inside the mounting base.

[0007] As a preferred technical solution of this utility model, a limiting plate is fixed at the upper end of the connecting pipe, one end of the guide pipe is fixed on the limiting plate and communicates with the inner cavity of the connecting pipe, and a slot is provided on the side of the buoyancy plate, which is matched with the guide pipe.

[0008] As a preferred embodiment of this utility model, a piston is slidably disposed inside the collection box, a positioning rod is slidably disposed on the upper side of the collection box, the bottom end of the positioning rod is connected and fixed to the middle of the side of the piston, a handle is fixed to the top of the positioning rod, a connecting pipe communicating with the inner cavity is installed on the lower side of the collection box, and the end of the guide pipe away from the connecting pipe is snapped into the connecting pipe.

[0009] As a preferred embodiment of this utility model, a valve is installed on the connecting pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. The sampling device for water quality testing in aquaculture according to this utility model involves inserting a positioning cylinder into the water when sampling aquaculture water. Then, the position of the sampling box is adjusted according to the sampling depth. During adjustment, the sampling box is moved inside the positioning cylinder by the connecting pipe. The positioning cylinder limits the movement of the sampling box to prevent the sampling box from being unable to reach the sampling depth due to buoyancy. The positioning cylinder also acts as a barrier to reduce disturbance to the aquaculture water during the movement of the sampling box, facilitating the sampling and testing of aquaculture water at different depths at that location.

[0011] 2. The aquaculture water quality testing and sampling device of this utility model involves inserting a guide tube into a connecting tube to connect the sampling box and the collection box. By pulling the positioning rod with a handle, the piston moves upward. During the piston movement, the collection box draws water from the sampling box through the guide tube in the connecting tube, facilitating the sampling of aquaculture water. After sampling, the valve on the connecting tube is closed, and then the guide tube is pulled out of the connecting tube. The valve seals the connecting tube, preventing the sampled aquaculture water from flowing out of the collection box.

[0012] 3. The aquaculture water quality testing and sampling device of this utility model allows the sliding installation cylinder to move outside the positioning cylinder according to the required sampling depth range before sampling, thereby adjusting the position of the buoyancy plate. During use, the buoyancy plate causes the sampling device to float on the water surface, facilitating its setup. The scale lines are used to control the sampling depth, making it easier to obtain water quality information at the sampling depth. After adjusting the position of the installation cylinder, its position can be fixed by tightening the positioning screw to prevent the installation cylinder from moving outside the positioning cylinder and affecting the use of the sampling device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a sampling device for water quality testing in aquaculture, comprising a positioning cylinder 1 and a collection box 9. A sampling box 2 is slidably installed inside the positioning cylinder 1. It should be noted that the positioning cylinder 1 has an elongated structure, and the sampling box 2 has a cylindrical structure. The outer side of the sampling box 2 contacts the inner side of the positioning cylinder 1. A connecting port is provided on the side of the positioning cylinder 1, and a sampling port is provided on the side of the sampling box 2. During sampling, the sampling port on the side of the sampling box 2 draws aquaculture water from the outside through the connecting port. A connecting pipe 3 is fixedly installed on the upper side of the sampling box 2. The upper end of the 3 extends to the outside of the positioning tube 1. The connecting tube 3 is made of rigid material. When sampling aquaculture water, the positioning tube 1 is inserted into the water. Then, the position of the sampling box 2 is adjusted according to the sampling depth. During the adjustment, the connecting tube 3 drives the sampling box 2 to move inside the positioning tube 1. The positioning tube 1 limits the movement of the sampling box 2 to prevent the sampling box 2 from being unable to reach the sampling depth due to buoyancy. The positioning tube 1 also acts as a barrier to reduce the disturbance to the aquaculture water during the movement of the sampling box 2, which facilitates the sampling and testing of aquaculture water at different depths at this location.

The end of the guide tube 5 away from the connecting pipe 3 is snapped into the connecting pipe 10. When sampling, the guide tube 5 is inserted into the connecting pipe 10 to realize the connection between the sampling box 2 and the collection box 9. The piston 12 is moved upward by pulling the positioning rod 13 with the handle 14. During the movement of the piston 12, the collection box 9 draws water from the sampling box 2 through the guide tube 5 in the connecting pipe 10, which facilitates the sampling of aquaculture water.

[0018] A valve 11 is installed on the connecting pipe 10. After sampling is completed, the valve 11 on the connecting pipe 10 is closed. Then the guide pipe 5 is pulled out from the connecting pipe 10. The valve 11 seals the connecting pipe 10 to prevent the sampled aquaculture water from flowing out of the collection box 9.

The positioning component includes an installation cylinder 6 sleeved on the outside of the positioning cylinder 1. A buoyancy plate 7 is fixed to the lower side of the installation cylinder 6. Before sampling, the installation cylinder 6 is slidably moved outside the positioning cylinder 1 according to the required sampling depth range to adjust the position of the buoyancy plate 7. During use, the buoyancy plate 7 is buoyed so that the sampling device floats on the water surface, which is convenient for setting up the sampling device. After the positioning cylinder 1 is inserted into the water, it can be left to stand for a period of time. After the water surface is calm, the aquaculture water can be sampled and tested through the sampling device. A scale line is set on the outside of the positioning cylinder 1 along its length. The scale line is used to control the setting depth of the sampling device to facilitate the acquisition of water quality information at the sampling depth.

[0020] A mounting base is fixed to the side of the mounting cylinder 6. A positioning screw 8 is provided inside the mounting base to position the mounting cylinder 6. After the position of the mounting cylinder 6 is adjusted, the positioning screw 8 can be tightened to position it, preventing the mounting cylinder 6 from moving outside the positioning cylinder 1 and affecting the use of this sampling device.

[0021] A limiting plate 4 is fixed to the upper end of the connecting pipe 3. The limiting plate 4 allows personnel to adjust the setting depth of the sampling box 2 through the connecting pipe 3. One end of the guide pipe 5 is fixed to the limiting plate 4 and communicates with the inner cavity of the connecting pipe 3. A slot is provided on the side of the buoyancy plate 7. The slot is matched with the guide pipe 5. After the sampling device is used, the guide pipe 5 is locked in the slot on the side of the buoyancy plate 7 for easy storage of the sampling device.

[0022] This aquaculture water quality testing and sampling device can sample aquaculture water at different depths according to testing needs.
