Description

Technical Field

[0001] This utility model relates to the field of seawater electrolysis technology, specifically to a device for measuring dissolved oxygen content before seawater electrolysis. Background Technology

[0002] In the field of seawater electrolysis, precise control of dissolved oxygen levels is crucial for electrolysis efficiency, equipment lifespan, and process stability. Typically, seawater requires pretreatment before electrolysis, followed by a check of dissolved oxygen levels. Currently, dissolved oxygen levels are often measured directly inside pipelines using probes. However, due to significant differences in light intensity, temperature, and biological activity at different depths, seawater exhibits marked stratification of dissolved oxygen levels, resulting in substantial variations in the dissolved oxygen content of extracted seawater.

[0003] Meanwhile, traditional devices have fixed probe positions that cannot be flexibly adjusted. Faced with seawater where dissolved oxygen levels are stratified and dynamically changing, fixed probes struggle to obtain comprehensive and accurate data, failing to meet the demands of precise monitoring. Furthermore, the probes, being immersed in seawater for extended periods, are prone to accumulating impurities, affecting detection accuracy. The fixed position also limits operating space during cleaning, increasing maintenance difficulty and raising operating costs and workload. Therefore, a dissolved oxygen measurement device before seawater electrolysis is proposed. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Please see Figure 1-5 A dissolved oxygen measuring device before seawater electrolysis includes a housing 1 for containing pretreated seawater; a venting component 2 and a support component 3 are provided on the housing 1, and a control panel 5 is installed on the outer wall of the housing 1; the venting component 2 is used to expel air from the housing 1 to ensure that the housing 1 is filled with seawater; the support component 3 includes a disc structure 301 disposed at the upper end of the housing 1, and a cylindrical structure 302 with external threads is fixedly connected to the bottom of the disc structure 301; a threaded hole is opened at the upper end of the housing 1, and the cylindrical structure 302 passes through the threaded hole and is threadedly connected to the housing 1; a detection component 4 is provided on the support component 3 for detecting the dissolved oxygen content of the seawater in the housing 1.

[0033] It should be noted that the support component 3 should be manufactured strictly in accordance with the technical requirements of the marine engineering field. For structures in contact with seawater, high-strength polymer materials, such as polyetheretherketone (PEEK), can be used, which is a common technology in this field. The main advantages of this material are its high strength and strong corrosion resistance, thereby enhancing the overall service life of the device.

[0034] It should be further noted that a sealing ring is provided at the threaded connection between the housing 1 and the cylindrical structure 302 of the support assembly 3 to further enhance the airtightness of the device.

[0035] In this embodiment, an inlet pipe 101 and an outlet pipe 102 are respectively provided on the bottom sides of the tank 1. The inlet pipe 101 is used to introduce pretreated seawater into the tank 1, and the outlet pipe 102 is used to discharge seawater from the tank 1 after the test is completed, realizing the circulation of seawater in and out, which facilitates multiple test operations. A graduated transparent observation window 103 is provided on one side wall of the tank 1. Through this observation window 103, the operator can intuitively observe the liquid level of the seawater in the tank 1. The graduations provide accurate liquid level data, thereby ensuring the accuracy of the test results.

[0036] In this embodiment, the venting component 2 includes a venting pipe 201 and a valve 202. The venting pipe 201 connects to one side of the upper end of the tank 1, and the valve 202 is disposed inside the venting pipe 201. When seawater is injected into the tank 1, the valve 202 is opened, allowing air inside the tank 1 to be discharged through the venting pipe 201, thereby ensuring that the tank 1 is filled with seawater and preventing residual air from interfering with the dissolved oxygen detection results. A liquid level sensor 203 is also disposed inside the venting pipe 201, located above the valve 202. When the seawater level rises to the position of the liquid level sensor 203, the liquid level sensor 203 will send a signal to prompt the operator to close the valve 202, preventing seawater from overflowing the venting pipe 201 and ensuring the normal operation of the device.

[0037] In this embodiment, the detection component 4 includes a detection box 401, a probe 402, and a wire 403. The detection box 401 is mounted on the upper end of the disc structure 301, and the probe 402 is connected to the detection box 401 via the wire 403. The detection box 401 is the core control part of the entire detection component 4, which can process and analyze the dissolved oxygen data of seawater collected by the probe 402. The probe 402 is in direct contact with the seawater to detect the dissolved oxygen level of the seawater in real time and transmits the detected signal to the detection box 401 via the wire 403. This design makes the structure of the detection component 4 clear, easy to install and maintain, and ensures the accuracy and timeliness of the detection data.

[0038] It should be noted that the wire 403 should be waterproofed during installation. The upper end of the wire 403 should pass through the disc structure 301 and the cylindrical structure 302 and be sealed. A certain length of the wire 403 inside the housing 1 should be reserved to ensure that the probe 402 will not pull the wire 403 and cause damage when it moves up and down.

[0039] In this embodiment, the support assembly 3 further includes a motor 303, a handle 304, a support box 305, a screw 306, and a clamping assembly 307. The motor 303 and the handle 304 are fixedly mounted on the upper end of the disc structure 301, and the support box 305 is vertically fixed to the lower end of the cylindrical structure 302. The motor 303 provides power for the up-and-down movement of the clamping assembly 307 and the probe 402. By controlling the forward and reverse rotation of the motor 303, the clamping assembly 307 and the probe 402 can slide up and down within the support box 305. The handle 304 facilitates manual rotation of the disc structure 301 by the operator, thereby facilitating the assembly and disassembly of the entire support assembly 3 and increasing the flexibility of the device. The support box 305 provides installation space for the screw 306 and the clamping assembly 307, ensuring their stable operation.

[0040] In this embodiment, the clamping assembly 307 includes a slider 3071, an elastic sheet 3072, and at least two rollers 3073. The slider 3071 is located inside the support box 305 and is threadedly engaged with the screw 306. When the motor 303 drives the screw 306 to rotate, the slider 3071 moves up and down along the screw 306, thereby causing the clamping assembly 307 to slide up and down as a whole. An opening is provided on one side of the support box 305. The elastic sheet 3072 is located outside the support box 305 and has an arc-shaped sheet structure. One end of the slider 3071 passes through the opening and is fixedly connected to the elastic sheet 3072. The elastic sheet 3072 is elastic and can firmly clamp the probe 402, making its axis perpendicular to the bottom surface of the housing 1, thereby improving the accuracy of the detection. Rollers 3073 are horizontally rotatable at both ends of the elastic sheet 3072 along the height direction. During the installation and removal of the probe 402, the rollers 3073 reduce the frictional resistance between the probe 402 and the elastic sheet 3072 by rolling horizontally, facilitating the installation and removal of the probe 402. Anti-slip rings 3074 are fitted onto the surface of the rollers 3073, preventing slippage during rolling and avoiding damage to the probe 402 during vertical sliding.

[0041] It should be noted that the elastic sheet is made of special stainless steel, which is a well-known technology in this field, so it will not be elaborated here.

[0042] In this embodiment, the control panel 5 is electrically connected to valve 202, level sensor 203, motor 303, and detection box 401. The control panel 5 serves as the operation and control center of the entire device. Operators can use the control panel 5 to open and close valve 202, regulating the inflow and outflow of seawater; receive level signals from level sensor 203 to monitor the seawater level inside box 1; control the start, stop, forward and reverse rotation, and speed of motor 303 to precisely adjust the position of probe 402; and acquire, display, and store dissolved oxygen data processed by detection box 401. Unified control of all components through the control panel 5 makes the operation of the device more convenient and intelligent, improving detection efficiency and accuracy.

[0043] In summary, this dissolved oxygen measurement device before seawater electrolysis, by setting up a support component 3 with adjustable height, uses a motor 303 to drive the screw 306 to rotate, which in turn drives the clamping component 307 and the probe 402 to slide up and down. The position of the probe 402 can be flexibly adjusted according to the stratification of dissolved oxygen in seawater, thereby obtaining comprehensive and accurate data, meeting the needs of precise monitoring, and effectively solving the problem of inaccurate detection caused by the fixed probe 402 in traditional devices.

[0044] The dissolved oxygen measuring device before seawater electrolysis uses a clamping assembly 307 with an elastic sheet 3072 to hold the probe 402 and rollers 3073 at both ends. This ensures that the axis of the probe 402 is perpendicular to the bottom surface of the housing 1, reduces frictional resistance during disassembly and assembly, and facilitates cleaning and maintenance. Meanwhile, the control panel 5 controls all components in a unified manner, making operation convenient, reducing operating costs and maintenance workload, and improving the practicality and convenience of the device.

[0045] The working principle of this dissolved oxygen measurement device before seawater electrolysis is as follows:

[0046] First, pretreated seawater is introduced into tank 1 through inlet pipe 101. During the seawater injection process, valve 202 in venting assembly 2 is opened to allow air inside tank 1 to be discharged through venting pipe 201, ensuring that tank 1 is filled with seawater. When the seawater level rises to the position of level sensor 203 inside venting pipe 201, level sensor 203 sends a signal, and the operator closes valve 202 according to the signal to prevent seawater from overflowing.

[0047] Next, the motor 303 is started via the control panel 5. The motor 303 drives the screw 306 to rotate. Because the slider 3071 in the clamping assembly 307 is threadedly engaged with the screw 306, the slider 3071 moves up and down along the screw 306, thereby causing the clamping assembly 307 and the probe 402 to slide up and down. The operator can precisely adjust the position of the probe 402 via the control panel 5, enabling the probe 402 to measure seawater at different locations within the tank 1 and obtain comprehensive and accurate dissolved oxygen data. The probe 402 transmits the detected dissolved oxygen signal to the detection box 401 via the wire 403. After processing and analyzing the signal, the detection box 401 transmits the results to the control panel 5 for display and storage.

[0048] After the test is completed, open the outlet pipe 102 to drain the seawater from the tank 1. When cleaning and maintenance of the probe 402 are required, rotate the support assembly 3 by gripping the handle 304 to remove the detection assembly 4 from the support assembly 3. Then, use the rollers 3073 at both ends of the elastic plate 3072 in the clamping assembly 307 to easily remove the probe 402 from the clamping assembly 307 for cleaning. After cleaning, reinstall it. The entire device is controlled by the control panel 5, making operation convenient. It effectively solves the problems of inaccurate detection and difficult cleaning and maintenance of the probe 402 caused by the fixed probe 402 in traditional devices, improving the accuracy and convenience of seawater dissolved oxygen measurement and reducing operating costs and maintenance workload.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
