Description

Technical Field

[0001] This utility model relates to the field of water body detection, specifically a water body detection device. Background Technology

[0002] Water body testing refers to the process of qualitative or quantitative analysis of various pollutants and water quality indicators in water bodies using physical, chemical, and biological technologies. Its core purpose is to assess water quality, identify the causes of pollution, provide early warning of environmental risks, and ensure water safety. COD detectors are one type of testing instrument.

[0003] Water quality testing devices are used to detect and analyze pollutants in water, and COD analyzers are one such instrument. Generally, the hole for inserting the test tube containing the test sample into a COD analyzer is of a fixed size, which requires a test tube of a specific size to be inserted for testing. This has limitations. If a test tube smaller than the insertion hole is inserted, it will cause shaking and affect the test results. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, conventional COD detectors have a fixed-size hole for inserting the test tube containing the test sample, requiring the use of a test tube of a specific size, which has limitations. If a test tube smaller than the insertion hole is used, it will cause shaking and affect the test results. This utility model proposes a water body detection device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a water body detection device, including a COD detector body, the COD detector body including a detector, a control screen fixedly connected to the top of the detector, a fixing plate fixedly connected to the inner cavity of the detector, a comparison tube and an insertion tube fixedly connected to the bottom of the fixing plate, a rotating cover movably connected to the inner cavity of the detector through a rotating shaft, and an elastic clamping mechanism provided on the surface of the insertion tube;

[0006] The elastic clamping mechanism includes clamping blocks and mounting blocks. There are four clamping blocks and eight mounting blocks. The inner side of every two mounting blocks is movably connected to the surface of one clamping block. The surface of the clamping block is movably connected to the inner cavity of the insertion tube. A rubber ring is movably connected to the inner cavities of the four clamping blocks. The rubber ring is sleeved on the outside of the insertion tube.

[0007] Preferably, a support shaft is fixedly connected to the inner side of each pair of mounting blocks, and the surface of the support shaft is movably connected to the inner cavity of the clamping block.

[0008] Preferably, the surface of the clamping block is provided with a snap-fit ​​groove, and the inner cavity of the snap-fit ​​groove is movably connected to the surface of the rubber ring.

[0009] Preferably, each of the clamping blocks has two limiting blocks fixedly connected to its surface, and the surface of the limiting blocks is in contact with the surface of the insertion tube.

[0010] Preferably, the surface of the insertion tube is fixedly connected with four fixing blocks, and the inner cavities of the four fixing blocks are movably connected to the surface of the rubber ring.

[0011] Preferably, the clamping block has a clamping groove on its inner side, and the clamping groove is arc-shaped.

[0012] Preferably, an anti-slip pad is fixedly connected to the inner cavity of the clamping groove, and the anti-slip pad is made of rubber.

[0013] The advantages of this utility model are:

[0014] This invention utilizes a COD detector body and an elastic clamping mechanism. When a test tube slightly smaller than the diameter of the insertion tube is inserted, the tube wall exerts an outward pushing force on the clamping block, while the elasticity of the rubber ring exerts an inward pushing force on the clamping block. When the test tube is fully inserted, it is clamped tightly by the clamping block. This solves the problem that conventional COD detectors have a fixed-size insertion hole for test tubes containing test samples, requiring the use of test tubes of a specific size, which is limiting. Furthermore, inserting a test tube smaller than the insertion hole can cause shaking and affect the test results. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a water body detection device. (Refer to...) Figure 1 and Figure 5 A water body detection device includes a COD detector body 1, which includes a detector 101. A control screen 102 is fixedly connected to the top of the detector 101. A fixing plate 104 is fixedly connected to the inner cavity of the detector 101. A comparison tube 105 and an insertion tube 106 are fixedly connected to the bottom of the fixing plate 104. A rotating cover 103 is movably connected to the inner cavity of the detector 101 through a rotating shaft. An elastic clamping mechanism 2 is provided on the surface of the insertion tube 106.

[0025] The elastic clamping mechanism 2 includes clamping blocks 201 and mounting blocks 202. There are four clamping blocks 201 and eight mounting blocks 202. The inner side of every two mounting blocks 202 is movably connected to the surface of one clamping block 201. The surface of the clamping block 201 is movably connected to the inner cavity of the insertion tube 106. The inner cavities of the four clamping blocks 201 are movably connected to a rubber ring 205, which is sleeved on the outside of the insertion tube 106.

[0026] Reference Figure 5 A support shaft 208 is fixedly connected to the inner side of each pair of mounting blocks 202. The surface of the support shaft 208 is movably connected to the inner cavity of the clamping block 201. The support shaft 208 provides support for the rotation of the clamping block 201, thereby improving the stability of the clamping block 201 during rotation.

[0027] Reference Figure 5The surface of the clamping block 201 is provided with a snap-fit ​​groove 209. The inner cavity of the snap-fit ​​groove 209 is movably connected to the surface of the rubber ring 205. The snap-fit ​​groove 209 provides snap-fit ​​space for the rubber ring 205 to snap into the inner cavity of the clamping block 201, thereby improving the stability of the rubber ring 205 snapping into the inner cavity of the clamping block 201.

[0028] Reference Figure 4 Each clamping block 201 has two limiting blocks 203 fixedly connected to its surface. The surface of the limiting block 203 is in contact with the surface of the insertion tube 106. The limiting block 203 limits the clamping block 201 when it rotates into the inner cavity of the insertion tube 106, thus preventing the clamping block 201 from rotating excessively and losing contact with the inner cavity of the insertion tube 106, which would cause displacement.

[0029] Reference Figure 4 The surface of the insertion tube 106 is fixedly connected with four fixing blocks 204. The inner cavity of the four fixing blocks 204 is movably connected to the surface of the rubber ring 205. The fixing blocks 204 fix the rubber ring 205 and prevent the rubber ring 205 from displacing and leaving its original working position when deformed.

[0030] Reference Figure 5 The clamping block 201 has a clamping groove 207 on its inner side. The clamping groove 207 is arc-shaped. The arc shape of the clamping groove 207 can increase the contact area between the clamping block 201 and the test tube, thereby increasing the clamping effect.

[0031] Reference Figure 5 An anti-slip pad 206 is fixedly connected to the inner cavity of the clamping groove 207. The anti-slip pad 206 is made of rubber. By setting the anti-slip pad 206, the friction between the clamping block 201 and the test tube wall is increased, making the clamping block 201 more stable when clamping the test tube.

[0032] Working principle: When water quality needs to be tested, first open the rotating cap 103, and insert the prepared test tube containing the test sample into the inner cavity of the insertion tube 106. If the diameter of the test tube is slightly smaller than the diameter of the insertion tube 106, the tube wall will cause the clamping block 201 to rotate outward around the support shaft 208 until the test tube is inserted into the appropriate position in the insertion tube 106. The elasticity of the rubber ring 205 will cause the clamping block 201 to generate an inward rotational force, thus clamping the test tube. The anti-slip pad 206 increases the friction between the clamping block 201 and the test tube, improving the clamping effect. The stability of the holding block 201 in clamping the test tube is ensured. Then, the rotating cover 103 is closed, and the water quality in the test tube is detected by the touch control screen 102. The result is displayed on the control screen 102. When the test tube is pulled out from the insertion tube 106, the elasticity of the rubber ring 205 will cause the holding block 201 to rotate towards the inside of the insertion tube 106 until the holding block 201 drives the limiting block 203 to contact the surface of the insertion tube 106, thus limiting the holding block 201 and preventing it from rotating too far into the inner cavity of the insertion tube 106 and dislodging.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
