Description

Technical Field

[0001] The invention relates to the technical field of water quality detection, and in particular to a mobile sampling device based on aquaculture water quality detection. Background Art

[0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic plants and animals under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial feeding and management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture includes extensive farming, intensive farming and high-density intensive farming. Extensive farming is to release seedlings in medium and small natural waters and grow aquatic products completely relying on natural bait, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive farming is to grow aquatic products in smaller water bodies by feeding and fertilizing, such as pond fish farming, cage fish farming and fence farming. High-density intensive farming uses methods such as flowing water, temperature control, oxygenation and feeding high-quality bait to carry out high-density farming in small water bodies to obtain high yields, such as high-density flowing water farming of fish and shrimp.

[0003] For example, a Chinese patent for a real-time mobile water quality monitoring device based on aquaculture, publication number CN115184086B, is equipped with a regional adjustment component. When sampling the water area, the drive box can drive the worm to rotate so that the lifting frame moves up and down on the guide rod, and the lifting frame drives the sampling tube on the mobile sampling support block on the connecting rod to sample different depths of the water area, thereby increasing the diversity of the detection results and improving the accuracy of monitoring. At the same time, when it is necessary to sample two adjacent points, one of the drive boxes drives the corresponding lifting frame to move, so that the connecting rod drives the sampling tube on the mobile sampling support block to move on the same horizontal plane, and then the water is sampled, which is convenient for sampling water at two adjacent points and improves detection efficiency.

[0004] However, in this collection mode, first, if the sampling vessel is placed directly vertically in the water, the sampling vessel will be filled up quickly, resulting in a low sample distribution rate and the need for rapid recovery. If the sampling vessel is placed obliquely in the water, the sample in the vessel will continue to interact with the outside, resulting in chaotic sample distribution and reducing the objectivity of the sampling results.

DETAILED DESCRIPTION

[0026] 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 described embodiments 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 creative work are within the scope of protection of the present invention. Example 1

[0027] See also Figure 1-3 A mobile sampling device for aquaculture water quality detection includes a floating plate 1, a bracket 2 is provided at the bottom of the floating plate 1, a placement seat 3 is installed on the bracket 2, and the placement seat 3 is used to place a sampling vessel; The placement seat 3 is provided with a first sliding adjustment mechanism 4, and the placement seat 3 is connected to the bracket 2 through the first sliding adjustment mechanism 4; The first sliding adjustment mechanism 4 includes a first sliding groove 41 provided on the placement seat 3 , and a first sliding block 42 adapted to the first sliding groove 41 is installed on the bracket 2 . The first sliding block 42 is slidably disposed in the first sliding groove 41 .

[0028] In this embodiment: the traditional mobile sampling device is set on the water surface through a float plate, and collects samples according to the flow direction of the river. However, in this collection mode, first, if the sampling vessel is set directly and vertically in the water, the sampling vessel will be quickly filled, resulting in a low distribution rate of the sample and the need for rapid recovery. If the sampling vessel is set obliquely in the water, the sample in the vessel will continue to interact with the outside, resulting in chaotic sample distribution and reducing the objectivity of the sampling results.

[0029] The cam 3 is provided with a first sliding adjustment mechanism 4, and the cam 3 is connected with the bracket 2 and the first sliding adjustment mechanism 4 so as to slide and rotate. The first sliding adjustment mechanism 4 includes a first sliding groove 41 provided on the cam 3, and a first sliding block 42 is rotatably provided on the bracket 2. The first sliding block 42 is also provided in the first sliding groove 41. The cooperation between the first sliding groove 41 and the first sliding block 42 makes the cam 3 in the cam 3 gradually change from an inclined state to a vertical state during the sampling process. In this process, as the cam 3 gradually increases in weight, the cam 3 will also slide toward its bottom on the bracket 2, thereby avoiding jamming between the cam 3 and the bracket 2.

[0030] By movably setting the placement seat 3 on the bracket 2, the placement seat 3 can change its angle and height as its weight increases during the sampling process, while expanding the sample range and avoiding rapid recovery to a certain extent. At the same time, the number of sampling times can be reduced and the objectivity of the sample can be improved. Example 2

[0031] See also Figure 1-3 , a matching adjustment mechanism 5 is provided on the bracket 2, and the first slider 42 is provided on the bracket 2 through the matching adjustment mechanism 5; The matching adjustment mechanism 5 includes a moving groove 51 provided on the bracket 2 , a moving block 52 is slidably disposed in the moving groove 51 , and the first sliding block 42 is rotatably mounted on the moving block 52 .

[0032] The matching adjustment mechanism 5 further includes a return spring 53 disposed on the moving block 52, and the moving block 52 is elastically connected to the bracket 2 via the return spring 53; A limited telescopic rod 54 is also provided on the bracket 2 , and the bracket 2 is also connected to the moving block 52 through the limited telescopic rod 54 , and the return spring 53 is sleeved on the outside of the limited telescopic rod 54 .

[0033] In the present embodiment: In order to enable the first slider 42 to rotate and slide on the bracket 2, a matching adjustment mechanism 5 is also provided on the bracket 2, and the matching adjustment mechanism 5 includes a moving groove 51 opened on the bracket 2, and a moving block 52 is slidingly provided in the moving groove 51, and the first slider 42 is rotatably provided on the moving block 52. By rotatably providing the first slider 42 on the moving block 52, the purpose of the placement seat 3 being able to slide on the bracket 2 and rotate on the bracket 2 through the cooperation of the first slider 42 and the moving block 52 is met.

[0034] At the same time, since the moving block 52 is also slidably arranged on the bracket 2 through the moving groove 51, the range in which the placement seat 3 can be adjusted on the bracket 2 is further increased, thereby avoiding jamming.

[0035] In order to provide a certain degree of support for the moving block 52 to prevent the moving block 52 from sliding too sensitively and causing the placement seat 3 to descend too deeply, a return spring 53 is also provided on the moving block 52, and the bracket 2 is also elastically connected to the bracket 2 via the return spring 53. The return spring 53 applies an elastic supporting force to the moving block 52 to prevent it from sliding easily.

[0036] In order to make the sliding of the moving block 52 more stable, a limiting telescopic rod 54 is also provided on the bracket 2, and 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 on the outside of the limiting telescopic rod 54. The limiting telescopic rod 54 limits the sliding of the moving block 52 and the elastic deformation of the return spring 53, thereby making the sliding of the moving block 52 more stable. Example 3

[0037] See also Figure 1-Figure 8 A clamp 7 is also provided on the bracket 2 , and two clamps 7 are symmetrically provided on the bracket 2 , and both of the clamps 7 are slidably provided on the bracket 2 .

[0038] An adaptive adjustment mechanism 8 is provided in the bracket 2, and the two clamps 7 are slidably arranged on the bracket 2 through the adaptive adjustment mechanism 8; The adaptive adjustment mechanism 8 includes a track groove 81 opened in the bracket 2 , a connecting block 82 is slidably arranged in the track groove 81 , and the clamp 7 is mounted on the connecting block 82 .

[0039] A second sliding adjustment mechanism 9 is also provided in the bracket 2, and the second sliding adjustment mechanism 9 is used to assist the connection block 82 in position adjustment; The second sliding adjustment mechanism 9 includes a second sliding groove 91 provided in the bracket 2 , a second sliding block 92 is slidably arranged in the second sliding groove 91 , a pressure spring 93 is arranged on the second sliding block 92 , and the second sliding block 92 is elastically connected to the connecting block 82 via the pressure spring 93 .

[0040] A guide rod 94 is also provided on the second sliding block 92 , and the connecting block 82 is slidably provided on the guide rod 94 .

[0041] In the present embodiment: in order to be able to seal the sampling vessel in time after it is vertically placed, thereby preventing the sample in the vessel from interacting with the outside world when the device is not immediately recovered, thereby causing the sample to become chaotic and lose objectivity, two clamps 7 are slidingly 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, and 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 flipped, thereby releasing the sealing plug to seal the vessel.

[0042] 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, and 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, thereby causing the distance between the two clamps 7 to increase accordingly, thereby allowing the sealing plug originally clamped by the two clamps 7 to cooperate with the vessel in the placement seat 3 to complete the sealing of the vessel.

[0043] In order to push the connecting blocks 82 away from each other during the sliding process, a second sliding adjustment mechanism 9 is further provided in the bracket 2. The second sliding adjustment mechanism 9 includes a second slide groove 91 opened in the bracket 2. The second slide groove 91 is connected to the track groove 81. A second slider 92 is slidingly provided in the second slide groove 91. A pressure spring 93 is provided on the second slider 92. The second slider 92 is elastically connected to the connecting block 82 through the pressure spring 93. By providing the pressure spring 93, the connecting blocks 82 will be affected by the elastic potential energy of the pressure spring 93 during the sliding process, thereby moving away from each other, and then the two clamps 7 are moved away from each other.

[0044] In order to make the connecting block 82 and the second slider 92 slide more stably when sliding synchronously, a guide rod 94 is further provided on the second slider 92, and the connecting block 82 is also slidably provided on the guide rod 94, and the sliding of the connecting block 82 is limited by the guide rod 94 to make its sliding more stable. Example 4

[0045] See also Figure 1-Figure 8 The bracket 2 is also provided with a pressing mechanism 11, which is used to limit the placement seat 3; The pressing mechanism 11 includes an arc-shaped sleeve 112 disposed on the bracket 2, an arc-shaped sleeve rod 111 is slidably disposed in the arc-shaped sleeve 112, and the arc-shaped sleeve rod 111 abuts against the placement seat 3; The arc-shaped sleeve rod 111 is also provided with a resistance ball 113 , which is used to limit the arc-shaped sleeve rod 111 .

[0046] A third sliding adjustment mechanism 13 is also provided in the bracket 2, and the arc sleeve 112 is slidably connected to the bracket 2 via the third sliding adjustment mechanism 13; The third sliding adjustment mechanism 13 includes a third sliding groove 131 provided on the bracket 2, and a third sliding block 132 adapted to the third sliding groove 131 is provided on the arc sleeve 112, and the third sliding block 132 is slidably provided in the third sliding groove 131; The third slider 132 is also provided with a connecting spring 133, and the third slider 132 is also elastically connected to the bracket 2 via the connecting spring 133; A limiting guide rod 134 is further disposed in the third sliding groove 131 , and the third sliding block 132 is slidably disposed on the limiting guide rod 134 .

[0047] An auxiliary rod 12 is also provided on the arc-shaped sleeve 112 , and the auxiliary rod 12 is used to cooperate with the placement seat 3 .

[0048] In this embodiment, in order to slow down the sensitivity of the placement seat 3 in angle adjustment to prevent it from flipping over too quickly, a pressing mechanism 11 is further provided on the bracket 2, which limits the placement seat 3. The pressing mechanism 11 includes an arc-shaped sleeve 112 arranged on the bracket 2, and an arc-shaped sleeve rod 111 is slidably arranged on the inner side of the arc-shaped sleeve 112, wherein one end of the arc-shaped sleeve rod 111 abuts against the placement seat 3, and the other end thereof is provided with a resistance ball 113. The resistance ball 113 is used to increase the resistance of the arc-shaped sleeve rod 111 and the arc-shaped sleeve 112, while also preventing the arc-shaped sleeve rod 111 from slipping out of the arc-shaped sleeve 112. By providing the pressing mechanism 11, the placement seat 3 is limited during the flipping process. Only when the force generated by the pressing mechanism overcomes the resistance between the resistance ball 113 and the inner wall of the arc-shaped sleeve 112, the placement seat 3 will rotate and push the arc-shaped sleeve rod 111 into the interior of the arc-shaped sleeve 112.

[0049] In order to align the placement seat 3 and the clamp 7 to facilitate sliding against the clamp 7, a third sliding adjustment mechanism 13 is also provided on the arc sleeve 112. The third sliding adjustment mechanism 13 is used to cooperate with the placement seat 3 so that the placement seat 3 is limited by the third sliding adjustment mechanism 13 after being flipped, thereby aligning the position of the clamp 7.

[0050] In order to prevent the telescopic distance between the arc sleeve rod 111 and the arc sleeve 112 from being insufficient to support the placement seat 3 to flip, a third sliding adjustment mechanism 13 is further provided on the bracket 2, and the arc sleeve 112 is slidably connected to the bracket 2 through the third sliding adjustment mechanism 13.

[0051] The third sliding adjustment mechanism 13 includes a third sliding groove 131 opened on the bracket 2, and a third slider 132 adapted to the third sliding groove 131 is arranged on the arc sleeve 112. The third slider 132 is slidably arranged in the third sliding groove 131. Through the cooperation of the third sliding groove 131 and the third slider 132, the arc sleeve 112 can slide a certain distance after being resisted by the placement seat 3, so as to adapt to the flipping of the placement seat 3 and the placement of the sealing plug by the clamp 7.

[0052] At the same time, in order to enable the arc sleeve 112 to automatically return to its original position after the device is removed, a connecting spring 133 is also provided on the third slider 132. The third slider 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 slider 132 can be pushed back to its initial position after the device is recovered.

[0053] In order to limit the sliding of the third slider 132 and the elastic deformation of the connecting spring 133, a limiting guide rod 134 is further provided in the third slide groove 131. The third slider 132 is slidably provided on the limiting guide rod 134 so that the third slider 132 can slide more stably in the third slide groove 131. The connecting spring 133 is sleeved on the outer side of the limiting guide rod 134 so that it will not bend when elastic deformation occurs, thereby hindering the sliding of the third slider 132.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
