Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, and in particular to a water quality detection and sampling device for a fish pond. Background Art

[0002] The existing device for testing the water quality of the fish pond takes samples through a water intake pipe entering the shallow water tank in the sampling chamber. When sampling of deep water is required, the motor is first turned on to generate power to drive the transmission rod to rotate. At this time, the transmission rod drives the gear to rotate the rotating column, and the rotation of the rotating column drives the moving column to move downward, so that the water intake pipe enters the deep water tank in the sampling chamber through the changing groove. The downward movement of the moving column causes the filter device to move downward into the deep water layer to collect deep water samples.

[0003] The above-mentioned device cannot sample the deep water layer when sampling the shallow water layer, and two operations are required to collect shallow and deep water samples. However, when the collection chamber is used for sampling the deep water layer after sampling from the shallow water layer, cross-contamination will occur, thereby introducing analysis errors, which in turn affects the analysis results of the deep water samples. Therefore, a fish pond water quality detection sampling device is needed. Utility Model Content

[0022] The following will be combined with 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.

[0023] Fish pond water sampling devices generally refer to equipment used to collect water samples from fish ponds or water bodies for water quality testing. These devices are designed to conveniently and accurately obtain water samples while maintaining representativeness for subsequent water quality analysis or monitoring.

[0024] Existing devices cannot sample the deep water layer when sampling the shallow water layer, requiring two operations to collect shallow and deep water samples. However, when the collection chamber is used to sample the deep water layer after sampling from the shallow water layer, cross contamination will occur, which will introduce analytical errors and affect the analytical results of the deep water samples. Figure 1-Figure 4 The embodiment provides a fish pond water quality detection sampling device, including a sampler 1 and a shallow water chamber 11 and a deep water chamber 12 opened inside the sampler 1.

[0025] The bottom of the sampler 1 is fixedly connected to a base 14, and the inside of the base 14 is fixedly connected to a gravity block 4 to reduce the interference of buoyancy in the water on the sampler 1 when collecting liquid. By adding the gravity block 4 at the bottom of the sampler 1, the total weight of the sampler 1 can be effectively increased, thereby reducing the interference of buoyancy on the sampler 1, making it easier for the sampler 1 to sink to the required depth, and collecting water samples more stably, ensuring the accuracy and reliability of water sample collection.

[0026] refer to Figure 2-Figure 3As shown, after the collection chamber is used for sampling from the shallow water layer and then for sampling from the deep water layer, cross contamination will occur, which will introduce analysis errors and further affect the analysis results of the deep water samples. In order to improve the reliability of the water sample analysis results, the following settings are made. The top of the sampler 1 is provided with a sampling mechanism 2 for simultaneously sampling liquid from the shallow water layer and the deep water layer. The sampling mechanism 2 includes a pull plate 21 provided on the top of the sampler 1. The bottom of the pull plate 21 is fixedly connected to the connecting rod 22. The outer wall of the connecting rod 22 is fixedly connected with two pistons 23 from top to bottom. The two pistons 23 are respectively sleeved on the inside of the shallow water chamber 11 and the deep water chamber 12. The sampler 1 is fixedly connected with a one-way suction pipe 24 and a one-way drainage pipe 25 that are fixedly connected to the inside of the shallow water chamber 11 and the deep water chamber 12. The one-way drainage One end of the water pipe 25 away from the sampler 1 is fixedly connected to a liquid collecting cylinder 26, and the other end of the liquid collecting cylinder 26 away from the sampler 1 is fixedly connected to a drainage pipe 27. After the sampler 1 is placed in the water and stabilized, sampling begins. The user pulls up the pull plate 21, so that the connecting rod 22 drives the two pistons 23 to move upward inside the shallow water chamber 11 and the deep water chamber 12. The negative pressure generated during the upward movement can suck the shallow water layer and the deep water layer liquid into the shallow water chamber 11 and the deep water chamber 12 respectively. When the user pushes down the pull plate 21, the connecting rod 22 drives the two pistons 23 to move downward inside the shallow water chamber 11 and the deep water chamber 12, thereby discharging the sucked liquid into the liquid collecting cylinder 26 respectively. After sampling is completed, the sampler 1 is stacked out of the water, and the valve of the drainage pipe 27 is opened to discharge the liquid into the test bottle for testing.

[0027] refer to Figure 2-Figure 4As shown, the one-way drainage pipe 25 fixedly connected to the inner cavity of the deep water chamber 12 contacts the shallow water layer during movement, which will cause the water in the shallow water layer to be partially sucked into the one-way water suction pipe 25 in some cases. This situation will affect the accuracy of the sample, especially when a pure deep water layer water sample is required. In order to further improve the accuracy of the sample, the following settings are made: the one-way water suction pipe 24 is provided with a sealing plate 241 at the end away from the sampler 1, and a sealing groove is provided at the end of the one-way water suction pipe 24 close to the sealing plate 241. A sealing ring adapted to the sealing groove is fixedly connected to the top of the sealing plate 241. The circumferential surface of the sampler 1 is fixedly connected to the side security plate 13. The top of the side security plate 13 is provided with an open pipe mechanism 3 for opening the pipe by synchronously driving the sampling mechanism 2 to make the sealing plate 241 away from the one-way water suction pipe 24. The open pipe mechanism 3 includes a sealing ring fixed at the top. The folding rod on the side of the pull plate 21 is rotatably connected to the power rod 31 at one end of the folding rod away from the pull plate 21. The thread on the outer wall of the power rod 31 is a specific angle thread, and the spacing between the threads is large. The inner wall of the side security plate 13 is fixedly connected to the driving ring 32 threadedly connected to the power rod 31. The outer wall of the power rod 31 is sleeved with a rotating cylinder 33 rotatably connected to the inner top wall of the side security plate 13, and a rotating groove is vertically opened on the inner wall of the rotating cylinder 33. The outer wall of the rotating cylinder 33 is threadedly connected to the rotating block slidably connected to the rotating groove, and the outer wall of the rotating cylinder 33 is threadedly connected to the reciprocating cylinder 34. The circumferential surface of the top of the reciprocating cylinder 34 is fixedly connected to the limited displacement block, and the inner side wall of the side security plate 13 is provided with a limiting groove for the vertical sliding of the limited displacement block, and the circumferential surface of the bottom end of the reciprocating cylinder 34 is fixedly connected to the connecting plate rod 35 fixedly connected to the circumference of the sealing tube plate 241. When the user pulls up the pull plate 21, the power rod 31 will move up synchronously and be threadedly connected to the drive ring 32 to drive the power rod 31 to rotate. The power rod 31 moves up and rotates to make the rotating cylinder 33 rotate in place. The rotation of the rotating cylinder 33 causes the reciprocating cylinder 34 to drive the connecting plate rod 35 to move down, thereby making the sealing tube plate 241 away from the one-way water suction pipe 24, so that the sample water can smoothly enter the shallow water chamber 11 and the deep water chamber 12, thereby improving the reliability of deep water layer water sample extraction.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
