Specific implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Please refer to Figures 1 to 7 , a water quality stability detection device for steelmaking, including a detector 1, a signal wire 3 is arranged on the detector 1, the other end of the signal wire 3 is provided with a probe 4, and the length of the signal wire 3 can be adjusted according to actual needs. By putting the probe 4 into the water, rapid detection of water quality can be achieved;

[0028] As a preference, a weight device can be arranged on the probe 4 to ensure that the probe 4 can reach the specified depth smoothly.

[0029] A protection cylinder 5 is fixedly installed on the probe 4, a filter cartridge 6 is slidably installed on the protection cylinder 5, and a bottom plate 7 is fixedly installed at the end of the filter cartridge 6 away from the protection cylinder 5;

[0030] Put the whole device into the water. At this time, the filter cartridge 6 is in a closed state. Through the cooperation of the protection cylinder 5 and the bottom plate 7, the water body can be prevented from entering in advance. The protection cylinder 5 and the filter cartridge 6 descend together until the predetermined detection depth is reached.

[0031] Inside the protective cylinder 5, a telescopic rod 10 is provided, and the other end of the telescopic rod 10 is fixedly installed on the filter cylinder 6; when the device reaches the designated depth, the filter cylinder 6 is lowered through the telescopic rod 10, and then part of the filter cylinder 6 is separated from the protective cylinder 5, allowing water to enter the filter cylinder 6. The filter cylinder 6 can block particles and algae, preventing them from directly contacting the probe 4 and affecting subsequent use. The water entering the filter cylinder 6 will contact the probe 4, and the probe 4 starts to detect water quality parameters. The data detected by the probe 4 is transmitted to the detector 1 through the signal line 3, and the detector 1 processes the data and displays various indicators of the water quality.

[0032] A scraper 11 is inlaid and installed on the protective cylinder 5, and the scraper 11 is in direct contact with the filter cylinder 6.

[0033] When the filter cylinder 6 moves, the scraper 11 will move relative to the filter cylinder 6, and the scraper 11 can block the impurities attached to the filter cylinder 6, thus facilitating subsequent use activities.

[0034] A sealing ring 12 is inlaid and installed on the periphery of the bottom plate 7, and the sealing ring 12 is in interference fit with the inner wall of the protective cylinder 5.

[0035] In this process, the sealing ring 12 on the bottom plate 7 ensures a tight fit between the filter cylinder 6 and the protective cylinder 5, preventing water from seeping in, thereby ensuring the accuracy of the measurement data.

[0036] An accommodation cavity 13 for accommodating the probe 4 is provided inside the protective cylinder 5, and the detection end of the probe 4 is inside the accommodation cavity 13.

[0037] A wire storage bin 2 is fixedly installed on the detector 1. Inside the wire storage bin 2, a rotating shaft 9 is rotatably installed. A wire winding roller 14 is fixedly installed on the rotating shaft 9. The wire winding roller 14 can wind the signal line 3, and one end of the rotating shaft 9 penetrates through the wire storage bin 2 and is fixedly installed with a rotating block 8.

[0038] By rotating the rotating block 8, the rotating shaft 9 can be rotated, thereby achieving the effect of storing or releasing the signal line 3. The function of automatically storing the signal line 3 not only simplifies the management of the signal line 3 but also reduces the risk of damage to the signal line 3 due to clutter.

[0039] A limiting rod 16 is slidably installed on the rotating block 8. On one side of the wire storage bin 2 facing the limiting rod 16, limiting holes 15 adapted to the limiting rod 16 are evenly opened at equal intervals in corresponding positions.

[0040] By adjusting the position of the limiting rod 16 and inserting it into a suitable limiting hole 15, the rotating shaft 9 can be prevented from rotating, and thus the length of the signal line 3 extending out can be stably controlled, facilitating detection activities at the same depth in different positions.

[0041] The working process of the present utility model: First, check whether components such as the detector 1, signal line 3, and probe 4 are in good condition. Adjust the length of the signal line 3 according to actual needs and fix it through the limit rod 16 and limit hole 15, so that the extended length of the signal line 3 remains at the required length. Ensure that the filter cartridge 6 is in a closed state, and the protection cylinder 5 and the filter cartridge 6 are closely attached through the sealing ring 12.

[0042] Slowly lower the entire device into the water. At this time, the filter cartridge 6 is in a closed state to prevent water from entering in advance. The protection cylinder 5 and the filter cartridge 6 descend together, and the signal line 3 is gradually pulled out as the device sinks until the predetermined detection depth is reached.

[0043] When the device reaches the specified depth, through the action of the telescopic rod 10, the filter cartridge 6 descends, and part of the filter cartridge 6 separates from the protection cylinder 5, allowing water to enter the filter cartridge 6. After the water enters the filter cartridge 6, due to the blocking effect of the filter cartridge 6, particles and algae are prevented from directly contacting the probe 4. The probe 4 starts to detect the water body and transmits the data through the signal line 3 to the detector 1. The detector 1 processes the data from the probe 4 and displays various indicators of the water quality.

[0044] After the detection is completed, lift the device out of the water. Before the lifting process, the telescopic rod 10 makes the filter cartridge 6 close again to prevent the water sample from overflowing, facilitating subsequent activities such as colorimetry.

[0045] By rotating the rotating block 8, retract the signal line 3 and fix it with the limit rod 16 to complete the storage of the signal line 3, and then collect the water sample.

[0046] When the filter cartridge 6 moves, the scraper 11 will move relative to the filter cartridge 6. The scraper 11 can block the impurities attached to the filter cartridge 6, thus facilitating subsequent use activities.

[0047] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
