Description

Technical Field

[0001] The utility model relates to the field of water quality detection, in particular to a sampling instrument used for water quality detection. Background Art

[0002] In order to protect water resources and prevent water pollution, it is necessary to conduct regular water quality testing on rivers so as to detect pollution in time and take corresponding measures. Water quality testing requires sampling through a sampler. In order to avoid residual contamination from the previous sampling and ensure the accuracy of the test, the existing sampling container needs to be rinsed with sampling water 3-4 times before formal sampling, and the sample needs to be placed in a storage container after sampling, which is inconvenient to use. Utility Model Content

[0003] The utility model aims to overcome the deficiencies of the prior art and provide a sampling instrument for water quality detection.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a sampling instrument for water quality detection, comprising a telescopic rod body, a fixing clamp is arranged at the front end of the telescopic rod body, the fixing clamp comprises a fixing part and a movable part, the fixing part is fixedly connected to the telescopic rod body, the movable part is hinged to the fixing part, a torsion spring is arranged between the movable part and the fixing part, the lower parts of the movable part and the fixing part form a cylindrical clamping part, and a sampling storage bottle is clamped on the clamping part.

[0005] Furthermore, the middle of the clamping part is recessed inward to form a limiting groove, and the inner surfaces of the clamping part on the upper and lower sides of the limiting groove are covered with an anti-slip layer.

[0006] Furthermore, the upper portion of the sampling storage bottle contracts inwardly to form a bottleneck, the middle portion of the bottleneck protrudes outwardly to form a limiting ring matching the limiting groove, the bottleneck is placed in the clamping portion, and the limiting ring is placed in the limiting groove.

[0007] Furthermore, the telescopic rod includes a gripping rod and an extension rod. The gripping rod is hollow inside and open at one end, and a first threaded portion is provided on the inner surface of the opening. The extension rod is inserted into the gripping rod, and a second threaded portion matching the first threaded portion is provided at the bottom of the extension rod. The length of the extension rod is longer than that of the gripping rod.

[0008] Furthermore, a limiting plate is provided at the bottom of the extension rod, and the diameter of the limiting plate is larger than the diameter of the extension rod.

[0009] Furthermore, a connecting rod is hinged on the top of the extension rod, and the end of the connecting rod is fixedly connected to the fixing piece.

[0010] Furthermore, a strap is fixed on the gripping rod.

[0011] The beneficial effects of the utility model are as follows: by detachably clamping the sampling storage bottle on the clamping part as a sampling container, using a new sampling storage bottle when sampling not only avoids sampling contamination caused by the previous sampling, but also the sampling storage bottle can be directly removed after sampling as a storage container, without the need to pack the samples into storage containers, which is more convenient to use; in addition, the use of a telescopic rod body makes it easy to shrink and fold the rod body when not in use, making it easy to carry.

DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings.

[0018] A sampling instrument for water quality detection, comprising a telescopic rod body, a fixing clamp 4 is arranged at the front end of the telescopic rod body, the fixing clamp 4 comprises a fixing part 41 and a movable part 42, the fixing part 41 is fixedly connected to the telescopic rod body, the movable part 42 is hinged to the fixing part 41, a torsion spring 43 is arranged between the movable part 42 and the fixing part 41, the lower part of the movable part 42 and the fixing part 41 forms a cylindrical clamping part 46, the clamping part 46 clamps a sampling storage bottle 5, the sampling storage bottle 5 is placed in water through the telescopic rod body for sampling, and after taking water, the fixing clamp 4 is opened to put the sampling storage bottle 5 can be taken down for storage, and a new sampling storage bottle 5 can be replaced when sampling next time, so there will be no residual contamination due to the last sampling, and there is no need to rinse the sampling bottle multiple times before sampling; in addition, the sampling storage bottle 5 of suitable material can be replaced according to the test items, such as using glass sampling bottles when testing organic compound items, and using plastic sampling bottles when testing sodium, calcium, magnesium, silicon and other items, to avoid contamination of the sample by the sampling container, and the sampling storage bottle can be used as a storage container, without the need to select a suitable storage container for subpackaging and storage according to the test items after sampling, which is more convenient to use.

[0019] Furthermore, the middle of the clamping portion 46 is recessed inward to form a limiting groove 44, and the inner surfaces of the clamping portion 46 on the upper and lower sides of the limiting groove 44 are covered with a rubber anti-skid layer 45. The upper portion of the sampling storage bottle 5 shrinks inward to form a bottleneck 51. After installation, the anti-skid layer 45 squeezes the bottleneck 51 to prevent the bottle from shaking. The middle portion of the bottleneck 51 protrudes outward to form a limiting ring 52 matching the limiting groove 44. The bottleneck 51 is inserted into the clamping portion 46, and the limiting ring 52 is inserted into the limiting groove 44, which can prevent the sampling storage bottle 5 from sliding downward.

[0020] Furthermore, the telescopic rod includes a gripping rod 1 and an extension rod 2. The gripping rod 1 is hollow inside and open at one end, and a first threaded portion 11 is provided on the inner surface of the opening. The extension rod 2 is inserted into the gripping rod 1, and a second threaded portion 21 matching the first threaded portion 11 is provided at the bottom. The extension rod 2 is longer than the gripping rod 1, and the extension rod 2 can be retracted into the gripping rod 1 to reduce the overall length for easy storage.

[0021] Furthermore, a limiting plate 22 is provided at the bottom of the extension rod 2, and the diameter of the limiting plate 22 is larger than the diameter 2 of the extension rod. After the extension rod 2 is extended and the holding rod 1 is twisted to thread the holding rod 1 and the extension rod 2, the limiting plate 22 on the extension rod 2 will contact the bottom of the first threaded portion 11 of the holding rod 1, thereby limiting the extension rod 2 from continuing to move upward and preventing the extension rod 2 from being completely pulled out.

[0022] Furthermore, a connecting rod 3 is hinged at the top of the extension rod 2, and the end of the connecting rod 3 is fixedly connected to the fixing member 41. The connecting rod 3 can be folded inwards for easy storage and carrying.

[0023] Furthermore, a strap 6 is fixed to the holding rod 1, and a main body 61 of the strap is fixed to the holding rod. A male surface of Velcro is provided on the main body 61 of the strap, and a female surface of Velcro is provided on a tie strap 62 extending from one side of the main body. In the storage state, the connecting rod 3 and the holding rod 1 can be easily tied together by the strap 6 to prevent them from falling apart. When needed, the telescopic rod can be unfolded by tearing off the Velcro.
