TECHNICAL FIELD

[0001] The utility model relates to seawater detection technical field, concretely is a kind of pH detector for seawater detection. BACKGROUND

[0002] Seawater pH detection refers to the process of measuring the concentration of hydrogen ions (H+) in seawater, and the result is usually expressed in terms of pH value, which is a dimensionless number used to quantify the acid-base properties of a solution, with a range of 0 to 14. Ocean pH is an important parameter in marine ecosystems, and has a significant impact on the survival and reproduction of marine organisms. Changes in ocean pH can affect the solubility of calcium carbonate in the ocean, which in turn affects the growth and shell formation of organisms such as corals and shellfish. Changes in ocean pH can also affect the way certain sound frequencies propagate in water, affecting the communication and navigation behaviors of marine organisms.

[0003] Current seawater collection techniques rely heavily on manual operation, with a complex process and safety risks. Specifically, the sampling personnel need to directly throw the collector into the sea on the ship, and then pull the filled seawater collection tank back through the pull rope connected to the collection tank, to complete the water sample collection at a single location. In order to improve the accuracy and reliability of the detection results, multiple point sampling is usually required, which means that the sampling personnel must repeatedly perform the above complex and time-consuming steps. This operation method not only has low efficiency, but also increases the operation difficulty and safety hazards, especially when trying to collect water samples at different depths. SUMMARY

[0010] Further, two sliding grooves are provided on the outside of the circular tube along the Z-axis direction, and the two sliding grooves are symmetrically distributed left and right.

[0011] Further, the transmission plate is slidingly connected in the inside of the two sliding grooves, and a certain movement space is reserved between the transmission plate and the inner top wall and the inner bottom wall of the sliding grooves.

[0012] Further, the closing cover is in the shape of a hollow rectangular parallelepiped with the side facing the storage bin missing.

[0013] Further, the length and width of the inner wall of the closing cover on the XY plane are respectively matched with the length and width of the outside of the storage bin on the XY plane.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figure 1 The pH detector for seawater detection in the embodiment is used for detecting the pH of seawater at different depths at the same time.

[0024] Specifically, it comprises a round pipe 1, a counterweight 2 and a detection assembly 3. The counterweight 2 is arranged at the bottom end of the round pipe 1, and the detection assembly 3 is arranged on the round pipe 1.

[0025] In actual arrangement, the counterweight 2 is arranged at the bottom end of the round pipe 1, so that the round pipe 1 can drive the detection assembly 3 to quickly extend into seawater, and the pH of seawater at different depths is detected by the detection assembly 3.

[0026] Please refer to Figures 2-3 In order to detect the pH of seawater at different depths, the detection assembly 3 in the embodiment comprises at least three storage bins 301 arranged in an up-down interval on the outer side of the round pipe 1, and the storage bin 301 is in the shape of a hollow long cuboid with a missing lower end face. At least three collars 302 are movably arranged on the outer side of the round pipe 1, and a connecting plate 303 is installed on the outer side of the collar 302. The connecting plate 303 is provided with a closure cover 304 at the end away from the collar 302.

[0027] The at least three closure covers 304 are respectively located below the at least three storage bins 301. A test paper box 305 is installed on the inner bottom wall of the closure cover 304. Part of the top of the test paper box 305 extends into the interior of the storage bin 301, and the end of the test paper box 305 away from the round pipe 1 is missing.

[0028] It should be noted that the distance between the adjacent two test paper boxes 305 is fifty centimeters.

[0029] A transmission plate 306 is slidably connected inside the circular tube 1, and at least three sets of rings 302 are in transmission connection with the transmission plate 306. An electric push rod 307 is installed at the top of the circular tube 1, and the output end of the electric push rod 307 is in transmission connection with the transmission plate 306.

[0030] In actual use, the circular tube 1 is placed in a detection area, and the circular tube 1 is moved downward by the addition of the counterweight 2. When the circular tube 1 falls to an appropriate depth, the output end of the electric push rod 307 is extended to push the transmission plate 306 to move downward, and the transmission plate 306 drives the rings 302 and the test paper box 305 in transmission with it to move downward during the downward movement, so that seawater enters the inside of the test paper box 305, and the test paper in the test paper box 305 detects the seawater.

[0031] In addition, after the seawater enters the inside of the test paper box 305, the output end of the electric push rod 307 is retracted to drive the closure cover 304 and the test paper box 305 to move upward, and the storage compartment 301 is closed by the closure cover 304 to prevent other depths of seawater from entering the inside of the storage compartment 301 and affecting the accuracy of the detection result.

The test paper in the test paper box 305 at different heights is used to detect seawater at different depths.

[0033] It should be noted that before detection, unused test paper is sequentially placed in the inside of the five test paper boxes 305.

[0034] Further, in order to ensure that the transmission plate 306 can effectively drive the rings 302, two sliding grooves are provided on the outside of the circular tube 1 in the Z-axis direction in the embodiment, the two sliding grooves are symmetrically distributed left and right, the transmission plate 306 is slidably connected inside the two sliding grooves, and a certain movement space is reserved between the transmission plate 306 and the inner top wall and the inner bottom wall of the sliding groove.

[0036] In actual setting, in order to effectively close the storage compartment 301 and ensure the sealing effect between the storage compartment 301 and the closure cover 304, the closure cover 304 in the embodiment is a hollow long rectangular solid with a missing side facing the storage compartment 301. The length and width of the inner wall of the closure cover 304 on the XY plane are respectively matched with the length and width of the outside of the storage compartment 301 on the XY plane.
