Description

Technical Field

[0001] The utility model relates to the technical field of water quality sampling inspection, in particular to a water quality sampling inspection tank. Background Technique

[0002] When conducting water quality detection, it is necessary to sample the water source. Due to the complex water quality environment during sampling, if irrelevant impurities cannot be filtered during sampling, the sampling and detection results will be affected. Therefore, some sampling devices generally have built-in filters for filtration. However, during actual sampling, some relatively large impurities such as algae may enter through the water inlet and block the filter holes, which requires manual cleaning after sampling, otherwise it will affect the next use, which is very troublesome; among them, some sundries such as algae float on the water surface or in the water. When sampling, placing the sampling device from the water surface into the water will be affected by sundries such as algae, and the sampling device needs to be manually closed to complete sampling. It is relatively complicated to manually close the operation while excluding the influence of sundries such as algae, and the sampling efficiency is low. At the same time, the current tubular sampling device has a small sampling volume.

[0003] Therefore, we propose a water quality sampling inspection tank to solve the above problems. Content of the Utility Model

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The sampling inspection tank adopts a groove body structure, and the sampling amount is larger than that of the existing sampling tube. When the sampling inspection tank is in use, it is slowly immersed from the water surface, and the water sample enters the groove body through a plurality of filter holes. The large filtering surface can avoid the situation of all blockages, and it can be directly cleaned by flushing after use, which is convenient for operation; after a certain amount of water sample enters, the restriction is released by floating the floating block, and the cover drives the three sealing plates to synchronously fall to close a plurality of filter holes to complete sampling; overall, when sampling and inspecting, it can ensure the quickness and effectiveness of taking water samples, is simple to operate, convenient to carry, and has a large sampling amount.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Referring to Figures 1 - 3 a water quality sampling inspection tank shown, including:

[0020] A tank 1 for sampling and holding water samples. The design of the tank 1 has a larger capacity compared to existing sampling tubes. A cover 2 is provided on the upper side of the tank 1 to seal the tank 1. A number of filter holes are provided on several side walls of the tank 1. When the tank 1 is slowly lowered into the water surface, the water sample enters the tank 1 through the several filter holes. The filter holes have a large area, are not easily blocked, and can be directly flushed and cleaned later. After sampling, it is necessary to seal the several filter holes to preserve the water sample. For this purpose, a sealing plate 3 corresponding to the several filter holes is provided in the tank 1. The several sealing plates 3 are all fixedly connected to the cover 2. The cover 2 is connected to the tank 1 through several connecting members to ensure the movement trajectory of the cover 2. Among them, the connecting member includes a moving strip 4 fixedly connected to the cover 2. A limiting hoop 5 is sleeved on the moving strip 4 and the limiting hoop 5 is fixedly connected to the inner wall of the tank 1, which can ensure the linear movement of the cover 2 and the sealing plate 3.

[0021] A limiting component for restricting the moving strip 4 is provided on the tank 1. The limiting component includes an L-shaped hook 9 rotatably provided on the inner wall of the tank 1. An open mouth for inserting the L-shaped hook 9 is provided on the side wall of the limiting hoop 5. A number of limiting grooves corresponding to the L-shaped hook 9 are evenly provided on the side wall of the moving strip 4. By inserting the L-shaped hook 9 into the open mouth and the limiting grooves, the moving strip 4 can be limited. At the same time, a torsion spring 10 for limiting is provided between the L-shaped hook 9 and the tank 1 to move the L-shaped hook 9 out of the open mouth. In order to ensure the limiting effect of the L-shaped hook 9 on the moving strip 4, a U-shaped bolt 11 is slidably provided on the side wall of the tank 1. A jack corresponding to the U-shaped bolt 11 is provided on the L-shaped hook 9, which can limit the position of the L-shaped hook 9 to ensure its limiting effect on the moving strip 4. At the same time, a floating block 12 is fixedly connected to the end of the U-shaped bolt 11 away from the L-shaped hook 9. After a certain amount of water sample is taken, the floating block 12 can be floated to drive the U-shaped bolt 11, releasing the restriction on the L-shaped hook 9, so that the cover 2 automatically falls to achieve the sealing effect, which is convenient for operation.

[0022] To facilitate the export of the sample, an open mouth is provided on the cover 2, and a sealing rotary cover 6 is fitted in the open mouth. The sealing rotary cover 6 is made transparent.

[0023] At the same time, after sampling, in order to ensure the sealing stability, a number of locking components 7 for fixing it to the tank 1 are evenly and fixedly provided on the side wall of the cover 2. Existing technologies can be used to fix the cover 2 on the tank 1.

[0024] The cover 2 needs to fall to achieve sealing. In order to ensure smooth falling, an annular counterweight 8 is fixedly provided on the upper end surface of the cover 2. At the same time, an inverted U-shaped handle 13 is fixedly provided at the upper end of the tank 1 to facilitate the holding operation of the whole device.

[0025] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
