Description

Technical Field

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

[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control. It generally includes the entire process from seedling to aquatic product under artificial feeding and management. In a broader sense, it can also include the enhancement of aquatic resources. Water quality testing is required in aquaculture, and sampling equipment is needed for water quality testing.

[0003] Currently, sampling is generally done by staff using bottles to take samples directly. However, since the bottles are open when inserted into the water, water can easily get in, making it impossible to sample deep water. This reduces the accuracy of the test and causes great inconvenience to the testing work. Utility Model Content

[0004] The purpose of this invention is to provide a sampler for aquaculture water quality testing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sampler for aquaculture water quality testing, comprising:

[0006] The grip has a sampling bottle at its bottom and a cap at its top. The cap has a sealing gasket on its bottom wall. An L-shaped bracket is fixedly attached to the sampling bottle. A pull rod is fixedly attached to the center of the top wall of the cap. The pull rod is slidably connected to the L-shaped bracket. A spring is fitted on the pull rod. The two ends of the spring are fixedly connected to the cap and the L-shaped bracket, respectively. A lanyard hole is provided at the top of the pull rod, and a pull rope is attached to the lanyard hole.

[0007] Preferably, a connecting seat is fixedly bonded to the side wall of the sampling bottle, the connecting seat has a through hole, the bottom end of the handle has a threaded groove, a stud is threadedly connected to the threaded groove, the connecting seat is sleeved on the stud through the through hole, and a knob is fixedly bonded to the bottom end of the stud.

[0008] Preferably, the grip is a multi-stage telescopic bar, which allows the grip to be adjusted in length as needed.

[0009] Preferably, the grip bar is provided with scale lines.

[0010] Preferably, the bottom of the sampling bottle is cone-shaped.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The cap of the sampling bottle of this utility model is sealed to the mouth of the sampling bottle by the elastic pressure of the set elastic spring. Driven by the adjustable length handle, it can be inserted into water at various depths and maintain a seal. After reaching the required depth, the cap can be opened by pulling the pull rope to facilitate water to enter the sampling bottle. After sampling is completed, the cap can be automatically pressed and sealed, so that the sampler can easily sample water quality at various depths.

[0013] 2. The sampling bottle of this utility model is fixedly installed at the bottom of the handle by the cooperation of the connecting seat, through hole, stud and knob, which facilitates the disassembly and assembly of the sampling bottle and makes it easy to pour out the sampled water for testing after the sampling bottle is removed, thus improving the convenience of use.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a sampler for aquaculture water quality testing, comprising:

[0020] The grip 1 has a sampling bottle 2 at its bottom and a cap 3 at its top. A sealing gasket 4 is provided on the bottom wall of the cap 3. An L-shaped fixing bracket 5 is fixedly attached to the sampling bottle 2. A pull rod 6 is fixedly attached to the center of the top wall of the cap 3. The pull rod 6 is slidably connected to the L-shaped fixing bracket 5. A spring 7 is sleeved on the pull rod 6. The two ends of the spring 7 are fixedly connected to the cap 3 and the L-shaped fixing bracket 5, respectively. A rope hole 8 is provided at the top of the pull rod 6, and a pull rope 9 is attached to the rope hole 8.

[0021] A connecting seat 10 is fixedly bonded to the side wall of the sampling bottle 2. The connecting seat 10 has a through hole 11. A threaded groove 12 is provided at the bottom end of the handle 1. A stud 13 is threadedly connected to the threaded groove 12. The connecting seat 10 is sleeved on the stud 13 through the through hole 11. A knob 14 is fixedly bonded to the bottom end of the stud 13. The sampling bottle 2 is fixedly installed at the bottom end of the handle 1 through the cooperation of the connecting seat 10, the through hole 11, the stud 13, and the knob 14, which facilitates the disassembly and assembly of the sampling bottle 2 and makes it easy to pour out the sampled water for testing after removing the sampling bottle 2.

[0022] The grip 1 is a multi-stage telescopic bar, which allows the grip 1 to be adjusted in length as needed.

[0023] The handle 1 is provided with a scale line 15, which makes it easy to observe the descent depth of the sampling bottle 2.

[0024] The bottom of the sampling bottle 2 is set in a cone shape. The cone shape design can reduce the disturbance to the water when the sampling bottle 2 descends, thereby improving the sampling accuracy.

[0025] Working principle: When using this utility model, first adjust the handle 1 to the required length, then use the handle 1 to lower the sampling bottle 2 to the required water depth. When the sampling bottle 2 descends to the required depth, pull the pull rope 9 upwards, causing the pull rod 6 to slide upwards on the L-shaped fixing frame 5. This causes the bottle cap 3 to detach from the bottle mouth of the sampling bottle 2, while simultaneously compressing the elastic spring 7. Water enters the sampling bottle 2 through the bottle mouth. Then, release the pull rope 9, allowing the bottle cap 3 to be pressed against the bottle mouth of the sampling bottle 2 under the elastic force of the compressed elastic spring 7, thus sealing the sampling bottle 2. Finally, the sampling bottle 2 can be removed.
