DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] like Figure 1 、 2 As shown, a water quality sampler for convenient sampling includes an inner cylinder 1 and an outer cylinder 2 which are arranged inside and outside and rotatably connected. The inner cylinder 1 has a closed chamber, in which a plurality of partitions 14 are arranged from top to bottom. The plurality of partitions 14 divide the closed chamber into a plurality of water storage chambers 13, and a water inlet 15 is provided on the side wall of each water storage chamber 13; the outer cylinder 2 is provided with a water inlet slot 22 which cooperates with each water inlet 15, and the water inlet slot 22 is communicated with the outside world; when in use, the outer cylinder 2 and the inner cylinder 1 rotate relative to each other so that each water inlet slot 22 is communicated with the corresponding water inlet 15, so that the water inlet 15 is communicated with the outside world, or each water inlet slot 22 and the corresponding water inlet 15 are staggered so that each water inlet 15 is closed.

[0031] It can be understood that the inner cylinder 1 and the outer cylinder 2 need to be rotatably arranged, and the corresponding inner cylinder 1 and the outer cylinder 2 are in a pipe structure, so that the inner cylinder 1 and the outer cylinder 2 can be sleeved, and the outer cylinder 2 and the inner cylinder 1 can rotate relative to each other. At the same time, the inner cylinder 1 of the present application is in a tubular structure arranged with upper and lower seals, so as to form a sealed chamber. Since a plurality of partitions 14 are arranged in the sealed chamber, the plurality of partitions 14 can separate the inner cylinder 1 into a plurality of water storage cavities 13. In the present application, the inner cylinder 1 is separated into five water storage cavities 13 by four horizontally arranged partitions 14, and the five water storage cavities 13 are arranged from top to bottom. The height of each water storage cavity 13 can be set according to the requirements, for example, the water sample to be sampled is at a depth of 50-60 cm below the water surface, and the height of each water storage cavity 13 can be set to 10 cm. When the inner cylinder 1 is lowered to about 60 cm below the water surface, the water storage cavity 13 located at the lowermost part can collect the water sample at a depth of 50-60 cm below the water surface. In order to achieve the purpose of water collection of the water storage cavity 13, each water storage cavity 13 in the present application is provided with a water inlet 15 on the side wall (the side wall of the inner cylinder 1), and a water inlet groove 22 cooperating with each water inlet 15 is arranged on the side wall of the outer cylinder 2. The water inlet groove 22 is communicated with the outside. And based on the close rotation of the inner cylinder 1 and the outer cylinder 2, when taking water, the water sampler is inserted into the water area to a predetermined depth, the inner cylinder 1 and the outer cylinder 2 are rotated relative to each other, and each water storage cavity 13 can guide the water body at different depths. Reverse rotation of the inner cylinder 1 or the outer cylinder 2, closing of each water inlet 15, and taking out of the water sampler from the water area can realize sampling of the water quality at the target depth of the water area, so as to improve the sampling accuracy of the target water quality and further improve the accuracy of water quality detection.

[0032] Since the rotation of the outer cylinder 2 can achieve the shielding of the water inlet 15, thereby achieving the closure of the water inlet 15, in order to avoid the water sample entering each water storage cavity 13 from the gap between the outer cylinder 2 and the inner cylinder 1 as much as possible, the inner wall of the outer cylinder 2 and the outer wall of the inner cylinder 1 are rotatably attached in the present application, so as to realize the rotation of the outer cylinder 2 and the inner cylinder 1 while avoiding the water quality entering the water storage cavity 13 from the gap as much as possible. Of course, the bottom of the outer cylinder 2 can also be sealed and attached to the outer bottom of the inner cylinder 1 to avoid water entering each water storage cavity 13 from the gap between the outer cylinder 2 and the inner cylinder 1 as much as possible.

[0033] In order to facilitate the relative rotation of the inner cylinder 1 and the outer cylinder 2, the inner cylinder 1 is provided with a rotating handle 11, and the outer cylinder 2 is provided with a rotating handle 21. Figure 1As shown, the present application is provided with a handle 12 vertically arranged on the upper end of the inner cylinder 1, the handle 12 is in a cylindrical structure, a rotating cylinder 21 is arranged on the upper end of the outer cylinder 2 and sleeved on the handle 12, the rotating cylinder 21 is in a hollow cylindrical structure, and the upper end of the handle 12 extends out of the upper end of the rotating cylinder 21. In use, the inner cylinder 1 is placed at the target depth under water, then an operator fixes the handle 12 with one hand and applies an external force on the rotating cylinder 21 with the other hand, the rotating cylinder 21 rotates to drive the outer cylinder 2 to rotate, so that the water inlet 15 and the corresponding water inlet slot 22 are opposite to each other, the water quality at the target depth is sampled by the water storage cavity 13, after sampling is completed, the rotating cylinder 21 is rotated in the opposite direction, the water inlet slot 22 on the outer cylinder 2 is misaligned with the corresponding water inlet 15, the water inlet 15 is closed, and then the water sampler is taken out of the water, and the water sampling operation is completed.

[0034] In the above operation, in order for the rotating angle of the outer cylinder 2 to realize the relative position of the water inlet 15 and the corresponding water inlet slot 22, an identification picture or an identification font can be arranged on the rotating cylinder 21, and an indication mark is arranged on the handle 12, the indication mark and the identification picture at different positions are opposite to each other, so as to determine the relative position of the water inlet 15 and the water inlet slot 22, and realize the water inlet or water storage of the water storage cavity 13.

[0035] During the water sampling process of the inner cylinder 1, if the inner cylinder 1 is arranged obliquely, the water introduced into each water storage cavity 13 and the water quality at the target depth will be deviated, in order to reduce the deviation, the inner cylinder 1 is provided with a plurality of water storage cavities 13 arranged in parallel and arranged in the same direction, and the water storage cavities 13 are arranged in the same direction. Figure 1 As shown, the present application is provided with a positioning cone 11 vertically arranged on the lower end of the inner cylinder 1, the positioning cone 11 is in a downward conical structure, and the positioning cone 11 is coaxially arranged with the inner cylinder 1 and the handle 12, and the bottom of the outer cylinder 2 is provided with a through hole for the positioning cone 11 to pass through. In use, the inner cylinder 1 is placed under water, the positioning cone 11 is inserted into the riverbed bottom (or other water bottom that can be inserted), and then the outer cylinder 2 is rotated to sample water and store water. The arrangement of the positioning cone 11 can ensure that the inner cylinder 1 is vertically arranged below the water surface as much as possible during water inlet, and reduce the deviation of the water quality sampling at the target depth caused by the inclination of the inner cylinder 1.

[0036] Since the water storage cavity 13 is only provided with one water inlet 15, when the water inlet 15 is communicated with the outside, the water inlet 15 needs to introduce water and discharge the air in the water storage cavity 13. In theory, the air pressure in the water storage cavity 13 is not enough to block the water from entering the water storage cavity 13, even if the water cannot fill the water storage cavity 13, part of the water can enter the water storage cavity 13, and the sampling purpose can be achieved.

[0037] In order to avoid the influence of the air pressure in the water storage cavity 13 on water sampling, the water storage cavity 13 is provided with a water inlet 15 and a water outlet 16 arranged on the same side of the water storage cavity 13. Figure 1 , 2As shown, the water outlet 16 is arranged on the side wall of the water storage cavity 13 (the inner wall of the inner cylinder 1), and each water outlet 16 is located below the corresponding water inlet 15. Meanwhile, the outer cylinder 2 is provided with a water outlet groove 23 matched with each water outlet 16, and the water outlet groove 23 is communicated with the outside. When each water inlet 15 is communicated with the outside, each water outlet 16 is communicated with the outside. When each water inlet 15 is closed, each water outlet 16 is closed. In use, the cooperation of the water outlet 16 and the water outlet groove 23 can increase a channel for the water storage cavity 13 to communicate with the outside. When the water storage cavity 13 is used to take water, the water inlet 15 and the water outlet 16 are both communicated with the outside, which is beneficial to the water entering the water storage cavity 13 and the air in the water storage cavity 13 being discharged, and is more beneficial to the water smoothly entering the water storage cavity 13 to achieve the goal of taking water.

[0038] In order to facilitate the flow of water in the water taking device, the water taking device is provided with a water inlet groove 22 on the outer side of each water inlet 15, and each water inlet groove 22 extends outwardly away from the outer cylinder 2. Figure 1 As shown, the water outlet 16 is arranged on the side wall of the water storage cavity 13 (the inner wall of the inner cylinder 1), and each water outlet 16 is located below the corresponding water inlet 15. Meanwhile, the outer cylinder 2 is provided with a water outlet groove 23 matched with each water outlet 16, and the water outlet groove 23 is communicated with the outside. When each water inlet 15 is communicated with the outside, each water outlet 16 is communicated with the outside. When each water inlet 15 is closed, each water outlet 16 is closed. In use, the cooperation of the water outlet 16 and the water outlet groove 23 can increase a channel for the water storage cavity 13 to communicate with the outside. When the water storage cavity 13 is used to take water, the water inlet 15 and the water outlet 16 are both communicated with the outside, which is beneficial to the water entering the water storage cavity 13 and the air in the water storage cavity 13 being discharged, and is more beneficial to the water smoothly entering the water storage cavity 13 to achieve the goal of taking water.

[0039] The outer cylinder 2 and the inner cylinder 1 are matched and rotated. In theory, the outer cylinder 2 and the inner cylinder 1 can be damped and rotated. However, even if the outer cylinder 2 and the inner cylinder 1 are damped and rotated, the outer cylinder 2 is easy to rotate along the inner cylinder 1 when the outer cylinder 2 is subjected to an external force. In order to avoid the relative rotation of the inner cylinder 1 and the outer cylinder 2 in the non-use state, as shown in Figure 3 、 4 As shown, the water taking device is provided with a limiting assembly 3 between the handle 12 and the rotating cylinder 21, and the limiting assembly 3 includes at least one limiting clamping groove 31 and at least one limiting clamping tooth 32. The limiting clamping groove 31 is selectively arranged on the handle 12 or the rotating cylinder 21, and the limiting clamping tooth 32 is located on the rotating cylinder 21 or the handle 12. The limiting clamping tooth 32 is arranged in an extension mode, so that the limiting clamping tooth 32 and the limiting clamping groove 31 are inserted or unlocked. The insertion of the limiting clamping tooth 32 and the limiting clamping groove 31 can lock the handle 12 and the rotating cylinder 21, so that the outer cylinder 2 and the inner cylinder 1 can be locked, and the relative rotation of the inner cylinder 1 and the outer cylinder 2 in the non-use state can be avoided. The separation of the limiting clamping tooth 32 and the limiting clamping groove 31 can unlock the outer cylinder 2 and the inner cylinder 1, and the outer cylinder 2 can be rotated under the driving of the rotating cylinder 21, which is convenient for the use of the water taking device.

[0040] In the application, the limiting clamping groove 31 is arranged on the inner wall of the rotating drum 21. When the outer drum 2 rotates along the inner drum 1, there are only two states, that is, the water inlet 15 is communicated with the outside and the water inlet 15 is closed. Therefore, it can be understood that the outer drum 2 has two stop positions along the rotating drum 21 of the inner drum 1, as shown in Figure 3 、 4 The application sets two limiting clamping grooves 31, which are arranged at intervals along the inner wall of the rotating drum 21, and the slot of the limiting clamping groove 31 is opposite to the handle 12. When the outer drum 2 and the inner drum 1 rotate relative to each other, the limiting clamping teeth 32 are inserted into any limiting clamping groove 31, so that the outer drum 2 has two stop positions relative to the inner drum 1, which is convenient for the use of the water taking device.

[0041] In order to facilitate the expansion and contraction of the limiting clamping groove 31, as shown in Figure 3 、 4 The application is provided with a mounting groove 121 on the handle 12, and the limiting clamping teeth 32 are embedded in the mounting groove 121, and a expansion spring 122 is arranged between the limiting clamping teeth 32 and the mounting groove 121. The limiting clamping teeth 32 need to expand and contract along the mounting groove 121, so external force is needed to drive the limiting clamping teeth 32 to retract in the mounting groove 121, so as to realize the separation of the limiting clamping teeth 32 and the limiting clamping groove 31. At this time, an action block can be arranged on the limiting clamping teeth 32, and a sliding groove for the action block to slide can be arranged in the mounting groove 121. Then, by applying external force to the action block, the limiting clamping teeth 32 can be retracted in the mounting groove 121, so as to realize the separation of the limiting clamping teeth 32 and the limiting clamping groove 31.

[0042] Of course, in order to facilitate the expansion and contraction of the limiting clamping teeth 32, and also realize the insertion and limiting of the limiting clamping teeth 32 and the limiting clamping groove 31, as shown in Figure 3 、 4 The application has a wedge-shaped insertion part 321 on the limiting clamping teeth 32, and an insertion groove is arranged in the limiting clamping groove 31 to cooperate with the insertion part 321. The insertion part 321 moves relative to the insertion groove to drive the limiting clamping teeth 32 to expand and contract. Due to the structure of the insertion part 321, when the external force applied to the rotating drum 21 is large enough (overcoming the elastic force of the expansion spring 122), the rotating drum 21 rotates to drive the insertion groove to rotate, and then the insertion part 321 is compressed under the action of the insertion groove to retract into the mounting groove 121, until the insertion part 321 and the insertion groove are separated, realizing the unlocking of the rotating drum 21 and the handle 12, and facilitating the water taking or water guiding of the water taking device.

[0043] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
