A mobile sampling device for aquaculture water quality detection

Abstract

The present invention discloses a mobile sampling device for aquaculture water quality detection, which relates to the technical field of water quality detection. In this mobile sampling device for aquaculture water quality detection, through the mutual cooperation of the first chute and the first slider, the utensil in the placement seat gradually changes from an inclined state to a vertical state during the sampling process. During this process, as the utensil gradually becomes heavier, the placement seat will also slide towards its bottom on the bracket, thereby avoiding jamming between the placement seat and the bracket. While expanding the sample range, to a certain extent, rapid recovery is avoided, the number of samplings can be reduced, and the objectivity of the sample can be improved. The adaptive adjustment mechanism can drive two clamps to slide on the bracket when the placement seat is flipped, so as to release the sealing plug to seal the utensil, thereby preventing the sample in the utensil from interacting with the outside world all the time when the device is not immediately recovered, which may lead to sample confusion and loss of objectivity.

Description

Technical Field

[0001] The present invention relates to the technical field of water quality detection, and particularly to a mobile sampling device for aquaculture water quality detection. Background Technique

[0002] Aquaculture is a production activity of artificially controlling the reproduction, cultivation, and harvesting of aquatic animals and plants. Generally, it includes the whole process of growing aquatic products from fry under artificial feeding and management. Broadly speaking, it can also include the enhancement of aquatic resources. Aquaculture has methods such as extensive culture, intensive culture, and high-density intensive culture. Extensive culture is to release fry in medium and small natural waters and rely entirely on natural bait to grow aquatic products, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive culture is to use methods of feeding and fertilizing to grow aquatic products in smaller water bodies, such as pond fish farming, cage fish farming, and enclosure culture. High-density intensive culture uses methods such as flowing water, temperature control, oxygenation, and feeding high-quality bait to conduct high-density farming in small water bodies to obtain high yields, such as high-density fish and shrimp farming in flowing water.

[0003] For example, a real-time mobile monitoring device for aquaculture water quality in a Chinese patent, with the publication number CN115184086B. This real-time mobile monitoring device for aquaculture water quality is provided with a regional adjustment component. When sampling a water area, the worm can be driven to rotate by the drive box, so that the lifting frame moves up and down on the guide rod. The sampling tube on the moving sampling support block on the connecting rod is driven by the lifting frame to sample different depths of the water area, increasing the diversification of the detection results and improving the accuracy of monitoring. At the same time, when sampling two adjacent points is required, one of the drive boxes drives the corresponding lifting frame to move, so that the connecting rod drives the sampling tube on the moving sampling support block to move on the same horizontal plane, and then samples the water, facilitating sampling of the water at two adjacent points and improving the detection efficiency.

[0004] However, in this sampling mode, first, if the sampling vessel is directly vertically arranged in the water, the sampling vessel will quickly be filled, resulting in a low distribution rate of the sample and the need for quick recovery. If the sampling vessel is inclined in the water, the sample in the vessel will always interact with the outside, resulting in chaotic sample distribution and reducing the objectivity of the sampling result.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0043] Please refer to Figures 1-3 , a mobile sampling device for aquaculture water quality detection, including a floating board 1. A bracket 2 is provided at the bottom of the floating board 1, and a placing seat 3 is installed on the bracket 2. The placing seat 3 is used to place the vessels for sampling;

[0044] A first sliding adjustment mechanism 4 is provided on the placing seat 3, and the placing seat 3 is connected to the bracket 2 through the first sliding adjustment mechanism 4;

[0045] The first sliding adjustment mechanism 4 includes a first chute 41 opened on the placing seat 3, and a first slider 42 adapted to the first chute 41 is installed on the bracket 2. The first slider 42 is slidably arranged in the first chute 41.

[0046] In this embodiment: For traditional mobile sampling devices, they are set on the water surface through a floating board and sample according to the flow direction of the river. However, in this sampling mode, first, if the sampling vessel is directly vertically arranged in the water, the sampling vessel will quickly be filled, resulting in a low distribution rate of the samples and the need for quick recovery. If the sampling vessel is inclined in the water, the samples in the vessel will always interact with the outside, resulting in chaotic sample distribution and reducing the objectivity of the sampling results.

[0047] Therefore, in order to improve the effectiveness of the samples and avoid too low a sample distribution rate, it is necessary to repeat and carry out a large number of collection operations. A bracket 2 is provided under the floating board 1, and a placement seat 3 is installed on the bracket 2. The placement seat 3 is used to place the utensils for sampling. At the same time, a first sliding adjustment mechanism 4 is provided between the bracket 2 and the placement seat 3. The placement seat 3 is connected to the bracket 2 through the first sliding adjustment mechanism 4 to perform sliding and rotation. The first sliding adjustment mechanism 4 includes a first sliding groove 41 opened on the placement seat 3. A first slider 42 is rotatably provided on the bracket 2, and at the same time, the first slider 42 is also arranged in the first sliding groove 41. Through the mutual cooperation of the first sliding groove 41 and the first slider 42, the utensils in the placement seat 3 gradually change from an inclined state to a vertical state during the sampling process. During this process, as the utensils gradually gain weight, the placement seat 3 will also slide on the bracket 2 towards its bottom, thereby avoiding jamming between the placement seat 3 and the bracket 2.

[0048] By movably arranging the placement seat 3 on the bracket 2, the placement seat 3 can change its angle and height during the sampling process as its weight increases, while expanding the sample range, to a certain extent avoiding rapid recovery, reducing the sampling times, and improving the objectivity of the samples. Embodiment 2

[0049] Please refer to Figures 1-3 , a cooperation adjustment mechanism 5 is provided on the bracket 2, and the first slider 42 is arranged on the bracket 2 through the cooperation adjustment mechanism 5;

[0050] The cooperation adjustment mechanism 5 includes a moving groove 51 opened on the bracket 2. A moving block 52 is slidably arranged in the moving groove 51, and the first slider 42 is rotatably installed on the moving block 52.

[0051] The cooperation adjustment mechanism 5 further includes a return spring 53 arranged on the moving block 52. The moving block 52 is elastically connected to the bracket 2 through the return spring 53;

[0052] A limit telescopic rod 54 is further provided on the bracket 2. The bracket 2 is also connected to the moving block 52 through the limit telescopic rod 54, and the return spring 53 is sleeved outside the limit telescopic rod 54.

[0053] In this embodiment: In order to enable the first slider 42 to rotate and slide on the bracket 2 at the same time, a cooperation adjustment mechanism 5 is further provided on the bracket 2. The cooperation adjustment mechanism 5 includes a moving groove 51 opened on the bracket 2. A moving block 52 is slidably arranged in the moving groove 51, and the first slider 42 is rotatably arranged on the moving block 52. By rotatably arranging the first slider 42 on the moving block 52, the purpose that the placement seat 3 can slide on the bracket 2 and can also rotate on the bracket 2 through the cooperation of the first slider 42 and the moving block 52 is achieved.

[0054] Meanwhile, since the moving block 52 is also slidably arranged on the bracket 2 through the moving groove 51, the adjustable range of the placing seat 3 on the bracket 2 is further improved, thus avoiding jamming.

[0055] In order to support the moving block 52 to a certain extent to prevent the moving block 52 from sliding too sensitively and causing the placing seat 3 to drop too deeply, a return spring 53 is also arranged on the moving block 52, and the bracket 2 is also elastically connected to the bracket 2 through the return spring 53. An elastic supporting force is applied to the moving block 52 through the return spring 53, so that it will not slide easily.

[0056] In order to make the moving block 52 slide more stably, a limiting telescopic rod 54 is also arranged on the bracket 2. The limiting telescopic rod 54 is arranged in the moving groove 51. At the same time, the moving block 52 is also connected to the bracket 2 through the limiting telescopic rod 54, and the return spring 53 is sleeved outside the limiting telescopic rod 54. The sliding of the moving block 52 and the elastic deformation of the return spring 53 are limited by the limiting telescopic rod 54, so that the moving block 52 slides more stably. Embodiment 3

[0057] Please refer to Figures 1-8 , two clamps 7 are also arranged on the bracket 2. The two clamps 7 are symmetrically arranged on the bracket 2, and both of the two clamps 7 are slidably arranged on the bracket 2.

[0058] An adaptive adjustment mechanism 8 is arranged in the bracket 2, and both of the two clamps 7 are slidably arranged on the bracket 2 through the adaptive adjustment mechanism 8;

[0059] The adaptive adjustment mechanism 8 includes an orbital groove 81 opened in the bracket 2. A connecting block 82 is slidably arranged in the orbital groove 81, and the clamp 7 is installed on the connecting block 82.

[0060] A second sliding adjustment mechanism 9 is also arranged in the bracket 2. The second sliding adjustment mechanism 9 is used to assist the connecting block 82 in position adjustment;

[0061] The second sliding adjustment mechanism 9 includes a second sliding groove 91 opened in the bracket 2. A second slider 92 is slidably arranged in the second sliding groove 91. A pressure spring 93 is arranged on the second slider 92, and the second slider 92 is elastically connected to the connecting block 82 through the pressure spring 93.

[0062] A guide rod 94 is also arranged on the second slider 92, and the connecting block 82 is slidably arranged on the guide rod 94.

[0063] In this embodiment: In order to be able to seal the sampling vessel in time after it is vertical, so as to avoid the sample in the vessel interacting with the outside world all the time when the device is not immediately recovered, resulting in the sample being chaotic and losing objectivity, two clamps 7 are also slidably arranged on the bracket 2, and the two clamps 7 are symmetrically arranged on the bracket 2. The two clamps 7 cooperate with each other to clamp the sealing plug of the sealed vessel. An adaptive adjustment mechanism 8 is also arranged in the bracket 2. The adaptive adjustment mechanism 8 can drive the two clamps 7 to slide on the bracket 2 when the placement seat 3 is turned over, so as to release the sealing plug to seal the vessel.

[0064] The adaptive adjustment mechanism 8 includes a track groove 81 opened on the bracket 2. The track groove 81 is trapezoidal, and the inner diameter of the track groove 81 gradually increases from one side to the other side. A connecting block 82 is slidably arranged in the track groove 81. The clamp 7 is installed on the connecting block 82. When the connecting block 82 slides in the track groove 81, the distance between the two connecting blocks 82 will gradually increase, resulting in the distance between the two clamps 7 also increasing accordingly. Furthermore, the sealing plug originally clamped by the two clamps 7 can cooperate with the vessel in the placement seat 3 to complete the sealing of the vessel.

[0065] In order to be able to push the connecting blocks 82 away from each other during the sliding process, a second sliding adjustment mechanism 9 is also arranged in the bracket 2. The second sliding adjustment mechanism 9 includes a second sliding groove 91 opened in the bracket 2. The second sliding groove 91 is communicated with the track groove 81. A second slider 92 is slidably arranged in the second sliding groove 91. A pressure spring 93 is arranged on the second slider 92. The second slider 92 is elastically connected to the connecting block 82 through the pressure spring 93. By setting the pressure spring 93, when the connecting block 82 slides, it will be affected by the elastic potential energy of the pressure spring 93, so as to move away from each other, and further make the two clamps 7 move away from each other.

[0066] In order to make the connecting block 82 and the second slider 92 slide more stably when sliding synchronously, a guide rod 94 is also arranged on the second slider 92. The connecting block 82 is also slidably arranged on the guide rod 94. The sliding of the connecting block 82 is limited by the guide rod 94 to make it slide more stably. Embodiment 4

[0067] Please refer to Figures 1-8 , a pressing mechanism 11 is also arranged on the bracket 2. The pressing mechanism 11 is used to provide a limit to the placement seat 3;

[0068] The pressing mechanism 11 includes an arc-shaped sleeve 112 arranged on the bracket 2. An arc-shaped sleeve rod 111 is slidably arranged in the arc-shaped sleeve 112. The arc-shaped sleeve rod 111 abuts against the placement seat 3;

[0069] The arc-shaped sleeve rod 111 is further provided with a contact ball 113, and the contact ball 113 is used to limit the arc-shaped sleeve rod 111.

[0070] A third sliding adjustment mechanism 13 is further provided inside the bracket 2, and the arc-shaped sleeve 112 is slidably connected to the bracket 2 through the third sliding adjustment mechanism 13;

[0071] The third sliding adjustment mechanism 13 includes a third chute 131 opened on the bracket 2, a third slider 132 adapted to the third chute 131 is provided on the arc-shaped sleeve 112, and the third slider 132 is slidably arranged in the third chute 131;

[0072] A connecting spring 133 is further provided on the third slider 132, and the third slider 132 is elastically connected to the bracket 2 through the connecting spring 133;

[0073] A limiting guide rod 134 is further provided in the third chute 131, and the third slider 132 is slidably arranged on the limiting guide rod 134.

[0074] An auxiliary rod 12 is further provided on the arc-shaped sleeve 112, and the auxiliary rod 12 is used to cooperate with the placing seat 3.

[0075] In this embodiment: In order to slow down the sensitivity of the placing seat 3 for angle adjustment to prevent it from flipping too quickly, a pressing mechanism 11 is further provided on the bracket 2. The pressing mechanism 11 limits the placing seat 3. The pressing mechanism 11 includes an arc-shaped sleeve 112 provided on the bracket 2. An arc-shaped sleeve rod 111 is slidably arranged inside the arc-shaped sleeve 112. One end of the arc-shaped sleeve rod 111 abuts against the placing seat 3, and a contact ball 113 is provided at the other end. The contact ball 113 is used to increase the resistance between the arc-shaped sleeve rod 111 and the arc-shaped sleeve 112, and can also prevent the arc-shaped sleeve rod 111 from sliding out of the arc-shaped sleeve 112. By providing the pressing mechanism 11, the placing seat 3 is limited during the flipping process. Only when the force generated by it overcomes the resistance between the contact ball 113 and the inner wall of the arc-shaped sleeve 112, the placing seat 3 will rotate and push the arc-shaped sleeve rod 111 into the arc-shaped sleeve 112.

[0076] In order to align the placing seat 3 with the fixture 7 to facilitate the sliding of the abutting fixture 7, a third sliding adjustment mechanism 13 is further provided on the arc-shaped sleeve 112. The third sliding adjustment mechanism 13 is used to cooperate with the placing seat 3, so that the placing seat 3 is limited by the third sliding adjustment mechanism 13 after flipping, so as to align the position of the fixture 7.

[0077] In order to prevent the telescopic distance between the arc-shaped sleeve rod 111 and the arc-shaped sleeve 112 from being insufficient to support the flipping of the placing seat 3, a third sliding adjustment mechanism 13 is further provided on the bracket 2, and the arc-shaped sleeve 112 is slidably connected to the bracket 2 through the third sliding adjustment mechanism 13.

[0078] The third sliding adjustment mechanism 13 includes a third sliding groove 131 formed in the bracket 2, and a third sliding block 132 adapted to the third sliding groove 131 is provided on the arc-shaped sleeve 112. The third sliding block 132 is slidably arranged in the third sliding groove 131. Through the cooperation of the third sliding groove 131 and the third sliding block 132, the arc-shaped sleeve 112 can slide a certain distance after being abutted by the placing seat 3, so as to adapt to the flipping of the placing seat 3 and the feeding of the sealing plug by the fixture 7.

[0079] Meanwhile, in order to enable the arc-shaped sleeve 112 to automatically reset to the original position after the device is removed, a connecting spring 133 is further provided on the third sliding block 132. The third sliding block 132 is elastically connected to the bracket 2 through the connecting spring 133. Through the elastic potential energy of the connecting spring 133, the third sliding block 132 can be pushed back to the initial position after the device is recycled.

[0080] In order to limit the sliding of the third sliding block 132 and the elastic deformation of the connecting spring 133, a limiting guide rod 134 is further provided in the third sliding groove 131. The third sliding block 132 is slidably arranged on the limiting guide rod 134 so that the third sliding block 132 slides more stably in the third sliding groove 131, and the connecting spring 133 is sleeved outside the limiting guide rod 134, so that it will not be bent when undergoing elastic deformation, thus preventing the sliding of the third sliding block 132.

[0081] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
