Technical Field

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

[0002] In aquaculture, water quality testing is required, and sampling equipment is needed to extract water samples for subsequent testing.

[0003] While existing aquaculture water quality testing sampling equipment can meet basic sampling needs and obtain multiple water samples simultaneously, the position of the sampling structure is often not flexibly and conveniently adjustable. This means that users need to spend time and effort adjusting the insertion depth of the sampling structure in the aquaculture pond when they need to obtain water samples at different depths. Therefore, it cannot fully meet people's needs and also affects the overall sampling efficiency. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a sampling device for aquaculture water quality testing. It not only meets the basic requirements for sampling aquaculture ponds, but also allows for flexible and convenient adjustment of the vertical position of the sampling structure, thereby fully meeting the sampling requirements for obtaining water samples at different depths at one time.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a sampling device for aquaculture water quality testing, including a U-shaped mounting frame, multiple mounting sleeves slidably disposed on the mounting frame, a first locking bolt for fixing the mounting frame on the mounting sleeve, multiple sampling syringes disposed in the fixing sleeve, a first fixing bolt for fixing the sampling syringes on the fixing sleeve, a pull rod slidably disposed on the top of the mounting frame, a U-shaped fixing frame disposed on the lower end of the pull rod and disposed on the outside of the multiple sampling syringes, a fixing sleeve slidably disposed on the fixing frame, a second locking bolt for fixing the fixing frame on the fixing sleeve, and a second fixing bolt for fixing the handle of the sampling syringe on the fixing sleeve.

[0006] As a further improvement of this utility model, the side end of the mounting bracket is also provided with a receiving groove that is misaligned with the first locking bolt, and the side end of the fixing bracket is also provided with a scale located in the receiving groove. The scale allows workers to more conveniently and accurately adjust the height of the sampling syringe, and also allows workers to easily adjust the depth of the sampling device inserted into the aquaculture pond.

[0007] As a further improvement of this utility model, the side end of the sampling syringe is provided with a first threaded fixing hole for screwing into the first fixing bolt. Through the cooperation of the first fixing bolt and the first threaded fixing hole, the sampling syringe and the mounting sleeve can be flexibly fixed.

[0008] As a further improvement of this utility model, the handle of the sampling syringe is provided with a second threaded fixing hole that is screwed into the second fixing bolt. Through the cooperation of the second fixing bolt and the second threaded fixing hole, the handle of the sampling syringe can be flexibly fixed to the fixing sleeve.

[0009] As a further improvement of this utility model, the mounting sleeve is provided with a mounting sliding hole that slides to connect with the side end of the mounting bracket, and the mounting sleeve is also provided with a sleeve connection hole that fits into the side end of the sampling syringe. The mounting sliding hole enables a sliding connection between the mounting sleeve and the mounting bracket, and the sleeve connection hole enables a sliding connection between the mounting sleeve and the sampling syringe.

[0010] As a further improvement of this utility model, the fixing sleeve is provided with a fixing sliding hole that slides to the side end of the fixing frame, and the fixing sleeve is also provided with a snap-fit ​​groove that engages with the handle of the sampling syringe. The fixing sliding hole enables the fixing sleeve to slide to the fixing frame; the snap-fit ​​groove enables the fixing sleeve to engage with the handle of the sampling syringe.

[0011] As a further improvement of this utility model, a handle is also provided on the pull rod. The handle allows for convenient lifting of the pull rod.

[0012] As a further improvement of this utility model, the mounting bracket is also provided with a third locking bolt that can abut against the connecting rod to fix the connection between the mounting bracket and the tie rod.

[0013] As a further improvement of this utility model, the first locking bolt, the first fixing bolt, the second locking bolt, the second fixing bolt, and the third locking bolt are all hand-tightening bolts. Workers can easily adjust the first locking bolt, the first fixing bolt, the second locking bolt, the second fixing bolt, and the third locking bolt by hand.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] Firstly, by sliding multiple mounting sleeves on the U-shaped mounting frame and fixing their positions with the first locking bolt, the vertical position of the sampling syringe can be flexibly adjusted. Secondly, by adopting a design that combines a pull rod with a U-shaped fixing frame, the handle of the sampling syringe can be fixed and released by the second locking bolt and the second fixing bolt, thereby enabling the equipment to flexibly obtain water samples at different depths at one time, meeting the needs of stratified water quality testing in aquaculture ponds.

[0016] Secondly, the third locking bolt can lock and fix the connection between the mounting bracket and the pull rod, preventing the pull rod and the fixing bracket from moving vertically relative to the mounting bracket and the sampling syringe due to misoperation, which could cause the water sample in the sampling syringe to be accidentally squeezed out or spilled.

Detailed Implementation

[0024] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0025] like Figure 1 , 4As shown, a sampling device for aquaculture water quality testing includes a U-shaped mounting frame 101. Multiple mounting sleeves 102 are slidably disposed on the mounting frame 101. First locking bolts 103 are screwed onto the mounting sleeves 102, which abut against the outer wall of the mounting frame 101 to fix the connection between the mounting sleeve 102 and the mounting frame 101. Multiple sampling syringes 104 are sleeved in a fixing sleeve 108, and first fixing bolts 105 are screwed onto the fixing sleeve 108 to secure the sampling syringes 104. A pull rod is also slidably disposed on the top of the mounting frame 101. 106. The top of the mounting bracket 101 is provided with a through hole that is slidably connected to the pull rod 106. The lower end of the pull rod 106 is provided with a U-shaped fixing bracket 107 that is sleeved on the outside of multiple sampling syringes 104. A fixing sleeve 108 is slidably provided on the fixing bracket 107. A second locking bolt 109 is screwed onto the fixing sleeve 108, which can abut against the outer wall of the fixing bracket 107 to fix the connection between the fixing bracket 107 and the fixing sleeve 108. A second fixing bolt 110 is screwed onto the fixing sleeve 108 for screwing and fixing the handle of the sampling syringe 104.

[0026] In this embodiment, the fixing bracket 107 is also slidably connected to the mounting sleeve 102, and the fixing sleeve 108 has a through hole 117 that is slidably connected to the side end of the fixing bracket 107. In another embodiment, the fixing bracket 107 is sleeved on the outside of the mounting sleeve 102. For example, the mounting bracket 101 and the mounting sleeve 102 are distributed in the left-right direction, and the fixing bracket 107 is distributed in the front-back direction. This will not be described in detail here.

[0027] like Figure 3 As shown, the sampling syringe 104 has a first threaded fixing hole 111 on its side end that is screwed into the first fixing bolt 105.

[0028] like Figure 3 As shown, the handle of the sampling syringe 104 has a second threaded fixing hole 112 that is screwed into the second fixing bolt 110.

[0029] The worker can fit the sampling syringe 104 into the mounting sleeve 102, then drive the first fixing bolt 105 through the side wall of the mounting sleeve 102 and screw it into the first threaded fixing hole 111 to fix the mounting sleeve 102 and the sampling syringe 104 together. Then loosen the first locking bolt 103, adjust the vertical position of the mounting sleeve 102 and the sampling syringe 104, and then drive the first locking bolt 103 through the side wall of the mounting sleeve 102 and abut against the mounting bracket 101 to complete the vertical position adjustment of the sampling syringe 104.

[0030] Then loosen the second locking bolt 109 and slide the fixed sleeve 108 until the fixed sleeve 108 is engaged with the handle of the sampling syringe 104. Then drive the second locking bolt through the side wall of the fixed sleeve 108 and abut against the fixed frame 107 to complete the vertical position adjustment of the fixed sleeve 108. Then drive the second fixing bolt 110 through the side wall of the fixed sleeve 108 and screw it into the second threaded fixing hole 112 to fix the fixed sleeve 108 with the handle of the sampling syringe 104.

[0031] Then, the mounting bracket 101, the fixing bracket 107, and multiple sampling syringes 104 can be inserted into the corresponding depth in the aquaculture pond. Then, the lever 106 can be pulled upward to drive the handles of the fixing bracket 107, the fixing sleeve 108, and the sampling syringes 104 to move upward, so that aquaculture water at different depths can enter the sampling syringes 104 to complete the sampling.

[0032] The device is then removed from the aquaculture pond. Next, the first fixing bolt 105 is separated from the first threaded fixing hole 111, releasing the fixation at the connection between the sampling syringe 104 and the mounting sleeve 102. The second fixing bolt 110 is separated from the second threaded fixing hole 112, releasing the fixation at the connection between the fixing sleeve 108 and the handle of the sampling syringe 104. The second locking bolt 109 is then loosened, releasing the fixation at the connection between the fixing sleeve 108 and the fixing frame 107. After that, the fixing sleeve 108 can be separated from the sampling syringe 104, and the sampling syringe 104 can be removed from the mounting sleeve 102. The water sample in the sampling syringe 104 can then be used for testing.

[0033] According to another embodiment of the present invention, such as Figure 1 As shown, the side end of the mounting bracket 101 is also provided with a receiving groove 201 that is misaligned with the first locking bolt 103, and the side end of the fixing bracket 107 is also equipped with a scale 202 located in the receiving groove. The scale 202 allows workers to more conveniently and accurately adjust the height of the sampling syringe 104, and also allows workers to conveniently adjust the depth of the sampling device inserted into the aquaculture pond.

[0034] According to another embodiment of the present invention, such as Figure 4 As shown, the mounting sleeve 102 has a mounting sliding hole 113 that slides to the side end of the mounting bracket 101, and a sleeve hole 114 that fits into the side end of the sampling syringe 104. The mounting sliding hole 113 enables the mounting sleeve 102 to slide to the mounting bracket 101, and the sleeve hole 114 enables the mounting sleeve 102 to slide to the sampling syringe 104.

[0035] According to another embodiment of the present invention, such as Figure 5As shown, the fixing sleeve 108 has a fixing sliding hole 115 that slides to the side end of the fixing frame 107, and the fixing sleeve 108 also has a locking groove 116 that engages with the handle of the sampling syringe 104. The fixing sliding hole 115 enables the fixing sleeve 108 to slide with the fixing frame 107; the locking groove 116 enables the fixing sleeve 108 to engage with the handle of the sampling syringe 104.

[0036] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, a handle 203 is also fixed to the pull rod 106. The handle 203 is a rectangular frame. The pull rod 106 can be easily pulled by using the handle 203.

[0037] According to another embodiment of the present invention, such as Figure 1 As shown, a third locking bolt 204 is also screwed onto the mounting bracket 101 to secure the connection between the mounting bracket 101 and the pull rod 106 by contacting the connecting rod. After the sampling syringe 104 completes sampling of the aquaculture water by the vertical movement of the pull rod 106, the third locking bolt 204 can be tightened, driving the third locking bolt 204 to pass through the side wall of the mounting bracket 101 and contact the pull rod 106, thereby securing the connection between the mounting bracket 101 and the pull rod 106. This prevents the water sample from being squeezed out due to accidental movement of the handle of the sampling syringe 104 caused by misoperation of the pull rod 106 or the fixing bracket 107.

[0038] According to another embodiment of this utility model, the first locking bolt 103, the first fixing bolt 105, the second locking bolt 109, the second fixing bolt 110, and the third locking bolt 204 are all hand-tightening bolts. Workers can easily adjust the first locking bolt, the first fixing bolt 105, the second locking bolt 109, the second fixing bolt 110, and the third locking bolt 204 by hand.

[0039] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
