Description

Technical Field

[0001] This utility model relates to the field of ozone detection technology, specifically to an ozone detector with adjustable length. Background Technology

[0002] An ozone sensor is a chemical sensor that operates based on an electrochemical reaction. The sensor typically consists of two electrodes: a working electrode and a reference electrode. The working electrode is usually coated with a catalyst to promote the electrochemical reaction of ozone. When ozone is present in the water, ozone molecules undergo a redox reaction with the catalyst on the working electrode, generating electrons. By measuring the current on the working electrode, the ozone concentration can be obtained; the higher the ozone concentration, the higher the current. The sensor converts the measured current signal into a corresponding ozone concentration value and outputs it digitally. However, existing ozone detectors have a fixed probe length, making it impossible to retract the probe cable and measure ozone content at different depths. Therefore, we propose an ozone detector with an adjustable length. Utility Model Content

[0003] This invention provides an ozone detector with an adjustable length, which has the advantage that the detection length of the ozone detection probe can be changed as the winding and unwinding of the reel changes, thus solving the problems mentioned in the background art.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 5 This utility model provides a technical solution: an ozone detector with adjustable length, including a detector, which includes a first housing 2, one end of which is connected to a second housing 13. The first housing 2 contains a rechargeable battery 19 and a control main board 17 connected to the rechargeable battery 19. The surface of the second housing 13 is provided with a display screen 8, and the surface of the first housing 2 is provided with operation buttons 1. The operation buttons 1, the display screen 8, and the control main board 17 are connected.

[0023] like Figure 4 As shown, the charging interface of the rechargeable battery 19 is connected to the charging motherboard 18. The charging port on the charging motherboard 18 is located on the first housing 2, which facilitates charging of the rechargeable battery 19.

[0024] Furthermore, a winding housing 4 is located below the detector, and a wire outlet 6 is located on one side of the bottom of the winding housing 4. For example... Figure 1 As shown, the winding housing 4 is specifically positioned below the second housing 13, as follows: Figure 3 As shown, a winding shaft 15 is coaxially arranged inside the winding housing 4, and the two ends of the winding shaft 15 are rotatably connected to the winding housing 4.

[0025] A connecting wire 7 is wound on the spool 15. An ozone detection probe 10 is mounted on the free end of the connecting wire 7. The connecting wire 7 is an umbilical cable, but other wire harnesses are also acceptable. The connecting wire 7 contains multiple strands of wire. The bottom of the connecting wire 7 is connected to the sensor support 12. The ozone detection probe 10 is mounted on the sensor support 12, and the depth sensor 11 is also mounted on the sensor support 12, forming a single unit with the ozone detection probe 10, reducing size and preventing them from becoming scattered. Specifically, the depth sensor 11 and the ozone detection probe 10 are connected to the connecting wire 7, with each strand corresponding to a different wire within the connecting wire 7.

[0026] It should be noted that the sensor support 12 also has another function: counterweight. That is, the sensor support 12 has a certain weight, so that the sensor support 12, the depth sensor 11 and the ozone detection probe 10 can form a whole with a certain weight. This whole can drive the connecting wire 7 to automatically droop when the wire is unwound, so as to prevent the connecting wire 7 from getting tangled in the winding housing 4.

[0027] The end of the connecting wire 7 away from the ozone detection probe 10 is fixed to the winding spool 15, so that when the connecting wire 7 is wound or unwound, the connecting wire 7 can be stably on the winding spool 15 and will not slip.

[0028] Next, an electric slip ring 14 is coaxially provided on one side of the winding housing 4. The rotor of the electric slip ring 14 is connected to the end of the winding shaft 15. The rotor terminal of the electric slip ring 14 is connected to the connecting line 7. When the electric slip ring 14 is connected to the rotating shaft (i.e., the winding shaft 15), the wire is passed through the inside of the shaft. Therefore, the end of the connecting line 7 is passed into the winding shaft 15 and connected to the rotor, so that the signal transmitted by the connecting line 7 is transmitted outward through the electric slip ring 14.

[0029] like Figure 3 As shown, the end of the winding shaft 15 away from the slip ring 14 is connected to the drive motor 16. The drive motor 16 is used to drive the winding shaft 15 to rotate. When the winding shaft 15 rotates clockwise, the connecting wire 7 releases the wire. When the winding shaft 15 rotates counterclockwise, the connecting wire 7 retracts the wire.

[0030] Furthermore, to prevent the drive motor 16 and the slip ring 14 from being exposed, mounting housings 5 ​​are coaxially provided on both sides of the winding housing 4. The drive motor 16 and the slip ring 14 are respectively housed within the mounting housings 5. It should be noted that the rotor of the slip ring 14 rotates with the winding shaft 15; in fact, the stator of the slip ring 14 is installed within the mounting housing 5, thus fixing the slip ring 14 in place. The stator terminals of the slip ring 14 and the drive motor 16 are connected to the control main board 17 via wires, as shown in the diagram. Figure 3 The point indicated by the middle arrow A;

[0031] To avoid exposed wires, such as Figure 1 and Figure 2 As shown, a sealing cover 3 is provided between the mounting housing 5 and the second housing 13. The sealing cover 3 is connected to the side of the winding housing 4. The wires are respectively set inside the sealing cover 3, that is, the wires pass through the sealing cover 3 and enter the second housing 13 before connecting to the control main board 17.

[0032] Furthermore, such as Figure 1 As shown, a detachable sealing cover 9 is provided at the cable outlet 6. Specifically, the sealing cover 9 is connected to the cable outlet 6 via a locking mechanism. During use, when the connecting wire 7 is completely wound onto the winding shaft 15, as shown... Figure 5 As shown, the ozone detection probe 10 and the depth sensor 11 are placed inside the sealed cover 9, at which point they can be like... Figure 5 Place them on a flat surface, just like before.

[0033] Based on the above embodiments, when the ozone detector proposed in this application is in use, the control drive motor drives the connecting wire 7 to release the wire, and the sensor support 12 is placed in the water. At this time, the depth sensor 11 is used to monitor the water depth, and the ozone detection probe 10 is used to monitor the ozone content in the water at a certain depth. The ozone detection probe 10 and the depth sensor 11 transmit this information to the control motherboard 17 in real time. After analysis, the control motherboard 17 displays the data on the display screen 8.

[0034] Furthermore, the drive motor can be controlled to continue rotating, allowing the ozone detection probe 10 and depth sensor 11 to rise and fall in the water, thus monitoring the ozone content in water at different depths.

[0035] Based on the above embodiments, further optimization can be achieved by providing a power indicator light on the charging motherboard 18, which is installed on the first housing 2.

[0036] Based on the above embodiments, it should be further explained that the operation button 1 includes a power button, a button for controlling the forward and reverse rotation of the drive motor, a reset button, etc.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
