[0003] High-temperature solid electrolyte phosphorus determination probes are key detection components, but they face the technical bottleneck of inconvenient replacement. Traditional phosphorus determination probes adopt an integrated structure. In alloy melts above 1600℃, the electrolyte is prone to aging and the electrodes are prone to wear. The service life is usually only 4-8 hours, and frequent replacement is required to maintain detection accuracy. However, due to its deep coupling with the sealing structure of the melting furnace, replacement requires disassembling complex flanges, cleaning high-temperature residues, and recalibrating, which makes the operation cumbersome.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1, by Figure 1 This invention relates to an online monitoring system for alloy composition with precise phosphorus content control. It includes a laser-induced breakdown spectroscopy detection unit 1 and a high-temperature solid electrolyte phosphorus determination probe. The high-temperature solid electrolyte phosphorus determination probe includes a signal transmission section 3, an electrolyte section 4, and an electrode section 5. The electrolyte section 4 is fixed to the bottom end of the signal transmission section 3, and the electrode section 5 is located at the bottom end of the electrolyte section 4. A connecting mechanism 2 is provided between the electrode section 5 and the electrolyte section 4. The laser-induced breakdown spectroscopy detection unit 1 is arranged next to the alloy melting furnace. Its high-energy laser emitter emits pulsed laser light onto the surface of the molten metal. The laser interacts with the melt to generate high-temperature plasma. When the plasma de-excites, it releases... The characteristic spectra of the emitted phosphorus are acquired by a fiber optic spectrometer. By analyzing the intensity distribution of the characteristic spectral lines of phosphorus, and combining it with a partial least squares calibration model, the phosphorus content of the melt is inverted in real time. At the same time, a high-temperature solid electrolyte phosphorus determination probe is used. It adopts a sandwich structure of ZrO2-based composite electrolyte and 4CaO·P2O5 phosphorus ion conductive layer. After being inserted into the melt, it forms an electrochemical cell. Based on the Nernst equation, the phosphorus activity is calculated in real time and converted into mass fraction by measuring the potential difference between the reference electrode and the working electrode. It forms a dual-redundant sensing architecture with LIBS detection data. The data is fused by Kalman filtering algorithm to control the detection uncertainty within ±0.0015%.

[0024] Specifically, by Figure 2-4 The connecting mechanism 2 includes an outer disk 201 fixed to the outside of the electrolyte section 4, and an outer disk 204 fixedly mounted on the outside of the electrode section 5. Two side grooves 206 are symmetrically arranged on the outer disk 204. Inner shafts 2014 are rotatably connected to the inner sides of both side grooves 206. Rotating plates 208 are fixedly sleeved on the outer sides of both inner shafts 2014. Side blocks 2012 are fixedly connected to the sides of the two rotating plates 208 that are close to each other. Slots 2011 are provided at the bottom of both side blocks 2012. A fixing ring 209 located above the outer disk 201 is fixedly sleeved on the outside of the electrolyte section 4. A lifting ring 2010 is provided between the fixing ring 209 and the outer disk 201. A cylinder 2015 is fixedly mounted between the lifting ring 2010 and the fixing ring 209. Located between two rotating plates 208, and with the lifting ring 2010 located at the bottom of two side blocks 2012, two insert blocks 2016 are symmetrically fixedly connected to the top of the lifting ring 2010. The two insert blocks 2016 are respectively inserted into two slots 2011. Two columns 2021 are symmetrically fixedly connected between the fixing ring 209 and the outer plate 201. The lifting ring 2010 is movably sleeved on the outside of the two columns 2021. Two side grooves 207 are symmetrically provided on the outer plate 201. The two rotating plates 208 are respectively inserted into the two side grooves 207. Two positioning blocks 203 are symmetrically fixedly connected to the outside of the outer plate 204. Two positioning rods 202 are symmetrically fixedly connected to the bottom of the outer plate 201. The two positioning blocks 203 are respectively sleeved on the outside of the two positioning rods 202.

[0025] In use, first place electrode segment 5 at the bottom of electrolyte segment 4, so that the two positioning blocks 203 are respectively fitted onto the outside of the two positioning rods 202. Then rotate the two rotating plates 208 until the two rotating plates 208 are respectively inserted into the two side slots 207. At this time, the two insert blocks 2016 are respectively located directly below the two slots 2011. Then start the cylinder 2015 to drive the lifting ring 2010 to slide upward along the two columns 2021 and drive the two insert blocks 2016 to rise until the lifting ring 2010 abuts against the two side blocks 2012. At the same time, the two insert blocks 2016 are respectively inserted into the two slots 2011, fixing the outer disk 204 and the outer disk 1 201, and fixing the electrode segment 5 and electrolyte segment 4. When the two insert blocks 2016 descend and are removed from the two slots 2011, the fixing of the outer disk 204 and the outer disk 1 201 can be released, and finally the electrode segment 5 can be quickly replaced.

[0026] Specifically, by Figure 4As shown, the top of the outer disk 201 is symmetrically and fixedly connected to two L-shaped round rods 2018, and a sliding plate 2019 is movably sleeved between the two L-shaped round rods 2018. The top of the sliding plate 2019 is symmetrically and rotatably connected to two movable rods 2020, and the top of the two movable rods 2020 is rotatably connected to the lifting ring 2010. The top of the sliding plate 2019 is symmetrically and fixedly connected to two limiting rods 2017, and the top of the outer disk 201 is symmetrically and fixedly connected to two limiting cylinders 205. Two rotating plates 208 abut against the two limiting cylinders 205 respectively. Both rotating plates 208 are provided with through holes 2013. The two limiting rods 2017 pass through the two through holes 2013 respectively, and the two through holes 2013 are inserted into the two limiting cylinders 205 respectively.

[0027] In operation, when the cylinder 2015 drives the lifting ring 2010 to slide upward along the two columns 2021, the two movable rods 2020 drive the slide plate 2019 to slide along the two L-shaped round rods 2018, and drive the two limiting rods 2017 to move, so that the two limiting rods 2017 pass through the two through holes 2013 respectively. When the two inserts 2016 are inserted into the two slots 2011 respectively, the two limiting rods 2017 are inserted into the two limiting cylinders 205 respectively, limiting the two rotating plates 208, so that the outer disk 204 is fixedly connected to the outer disk 1 201, and finally ensuring the stability of the electrode segment 5 after installation.
