Description

Technical Field

[0001] This utility model relates to the field of cable production equipment technology, and in particular to a monitoring system for ultraviolet crosslinking equipment used in the production of new energy cables. Background Technology

[0002] With the rapid development of the new energy industry, the performance requirements of new energy cables, as key components for power transmission and distribution, are increasingly stringent. Ultraviolet (UV) crosslinking technology, as a highly efficient and environmentally friendly cable production process, is widely used in the production of new energy cables. UV crosslinking causes a crosslinking reaction in the cable insulation material through UV irradiation, thereby improving the cable's heat resistance, mechanical strength, and electrical performance. However, in actual production, especially in the production of new energy cables, the operating environment is more demanding, thus requiring higher standards for the crosslinking process. Current UV crosslinking equipment faces the following technical challenges: 1. UV irradiation uniformity: The effectiveness of UV crosslinking is highly dependent on the uniformity of UV irradiation. If the UV light is unevenly distributed on the cable surface, it can lead to over- or under-crosslinking in some areas, affecting the overall performance of the cable. Traditional UV crosslinking equipment lacks real-time monitoring methods for UV light uniformity, relying mainly on manual experience to adjust the light source position and power, making it difficult to guarantee irradiation uniformity. 2. Online detection of crosslinking effect: The evaluation of the crosslinking effect usually requires laboratory testing after production, making real-time monitoring impossible. This lag means that process parameters cannot be adjusted in a timely manner during production, which may result in a large number of defective products. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a monitoring system for ultraviolet crosslinking equipment in the production of new energy cables, which can monitor the uniformity of ultraviolet irradiation in real time and detect the crosslinking effect online, so as to improve the quality and efficiency of new energy cable production.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A monitoring system for ultraviolet crosslinking equipment used in the production of new energy cables includes an ultraviolet crosslinking device. The ultraviolet crosslinking device is equipped with a crosslinking cable pipe for the cable to pass through and crosslink. The crosslinking cable pipe has a crosslinking open area in the crosslinking region of the ultraviolet crosslinking device. Multiple ultraviolet lamps are arranged around the crosslinking open area of ​​the crosslinking cable pipe. Multiple ultraviolet light sensors are arranged around the axis of the pipe in the crosslinking open area. The ultraviolet light sensors are used to detect the ultraviolet light intensity at different positions of the cable.

[0006] The aforementioned ultraviolet light sensor is electrically connected to the transmitter, the transmitter is electrically connected to the input terminal of the analog quantity module, and the analog quantity module is communicatively connected to the crosslinking controller.

[0007] The output of the aforementioned analog module is electrically connected to the UV lamp control driver, and the UV lamp control driver is electrically connected to the UV lamp tube.

[0008] The aforementioned ultraviolet light sensors are installed at multiple locations along the axis of the cross-linked cable conduit.

[0009] The outlet end of the aforementioned cross-linked cable duct is equipped with a monitoring pipe rack, which is equipped with an infrared spectral detector.

[0010] The aforementioned infrared spectral detectors are installed in multiple locations along the cable axis on the monitoring pipe rack.

[0011] The aforementioned infrared spectral detector is connected to the spectral processor, which in turn is connected to the crosslinking controller.

[0012] The aforementioned cross-linked cable conduits are made of quartz.

[0013] This utility model provides a monitoring system for ultraviolet crosslinking equipment used in the production of new energy cables, which has the following beneficial effects:

[0014] 1. Improve the uniformity of ultraviolet light irradiation and ensure product quality; real-time monitoring of ultraviolet light intensity distribution through multi-point ultraviolet light sensors ensures that the ultraviolet light intensity received by each area of ​​the cable surface is uniform, and the power of the ultraviolet light source is automatically adjusted to avoid the problem of excessive or insufficient cross-linking caused by uneven irradiation. The multi-point monitoring technology generates an ultraviolet light intensity distribution map, which intuitively reflects the uniformity of irradiation.

[0015] 2. Real-time online detection of cross-linking effect to improve production efficiency; Real-time detection of chemical bond changes or temperature distribution on cable surface using infrared spectrometer or thermal imager to evaluate cross-linking effect. Online detection avoids the lag of traditional laboratory testing and can promptly identify and correct problems in production.

[0016] 3. Optimize production processes and reduce scrap rate; by real-time monitoring of UV light uniformity and cross-linking effect, automatically adjust process parameters (such as UV light intensity, irradiation time, cable conveying speed, etc.) to ensure that the cross-linking effect of each cable section meets the standard, reduce scrap caused by improper process parameters, and lower production costs.

Detailed Implementation

[0024] Example 1:

[0025] like Figure 1-5 As shown, a monitoring system for ultraviolet crosslinking equipment used in the production of new energy cables includes an ultraviolet crosslinking device 1. The ultraviolet crosslinking device 1 is provided with a crosslinking cable pipe 4 for the cable to pass through and crosslink. The crosslinking cable pipe 4 has a crosslinking opening area 5 in the crosslinking area of ​​the ultraviolet crosslinking device 1. Multiple ultraviolet lamps 6 are arranged around the crosslinking opening area 5 of the crosslinking cable pipe 4. Multiple ultraviolet light sensors 7 are arranged around the pipe axis in the crosslinking opening area 5. The ultraviolet light sensors 7 are used to detect the ultraviolet light intensity at different positions of the cable.

[0026] Multiple high-precision ultraviolet light sensors are arranged within the irradiation area of ​​the ultraviolet crosslinking equipment to monitor the ultraviolet light intensity at different locations in real time. An ultraviolet light intensity distribution map is generated through the sensor network to ensure that the ultraviolet light intensity received by each area on the cable surface is uniform.

[0027] The aforementioned ultraviolet light sensor 7 is electrically connected to the transmitter 10, the transmitter 10 is electrically connected to the input terminal of the analog quantity module 11, and the analog quantity module 11 is communicatively connected to the crosslinking controller 9.

[0028] The output terminal of the aforementioned analog module 11 is electrically connected to the ultraviolet lamp control driver 12, and the ultraviolet lamp control driver 12 is electrically connected to the ultraviolet lamp tube 6.

[0029] The detection signal from the ultraviolet light sensor 7 is converted by the transmitter 10 and then sent to the analog module 11. The analog module 11 converts the analog signal of ultraviolet light intensity into a digital signal that can be recognized by the crosslinking controller 9. The ultraviolet light intensity of the cable in different directions is detected by multiple ultraviolet light sensors 7 at different positions and an ultraviolet light intensity distribution map is generated. The crosslinking controller 9 controls the power of the ultraviolet lamps 6 at different positions according to the ultraviolet light distribution to ensure and monitor the uniformity of ultraviolet light in the crosslinking of the cable.

[0030] The aforementioned ultraviolet light sensor 7 is installed at multiple locations along the axis of the cross-linked cable conduit 4.

[0031] By setting up multiple ultraviolet detectors along the axis, a more detailed and accurate ultraviolet intensity distribution map of the cross-linked region can be generated.

[0032] The outlet end of the aforementioned cross-linked cable conduit 4 is equipped with a monitoring pipe rack 2, and the monitoring pipe rack 2 is equipped with an infrared spectral detector 3.

[0033] By installing an infrared spectroscopy detection device at the outlet of the cross-linked cable conduit 4, the changes in chemical bonds on the cable surface can be detected in real time. By analyzing the infrared spectral data, it can be determined whether the degree of cross-linking meets the requirements.

[0034] The aforementioned infrared spectral detectors 3 are provided in multiple locations along the cable axis on the monitoring tube rack 2.

[0035] The infrared spectral detector 3 is connected to the spectral processor 8, and the spectral processor 8 is communicatively connected to the crosslinking controller 9.

[0036] By installing multiple infrared spectral detectors 3 on the outside of the cable and processing the spectral detection signals through a spectral processor 8, the cross-linking status of the cable's outer surface can be comprehensively monitored. The monitoring signals are then transmitted to the cross-linking controller 9, which combines ultraviolet light uniformity monitoring with online detection of cross-linking effects to build an integrated monitoring system. Through multi-point ultraviolet light sensors and infrared spectrometers, the uniformity of ultraviolet light irradiation and the cross-linking effect can be monitored in real time.

[0037] The aforementioned cross-linked cable conduit 4 is made of quartz.

[0038] Quartz tubing is stable and insensitive to light, providing an excellent cross-linking environment for cables.
