Description

Technical Field

[0001] The invention relates to the technical field of water pollution detection, in particular to a sewage detection method for extinguishing a burning cable. Background Art

[0002] Cable fire is a serious fire accident, which will not only cause property loss, but also have a serious impact on the environment. After the cable catches fire, one of the common ways to extinguish the fire is to use water to extinguish it. However, since cables are usually made of a variety of materials, including metal conductors, insulation layers, sheaths, etc., these materials will release a large amount of harmful substances during the combustion process, such as heavy metals, toxic smoke, etc. When the fire-extinguishing water is mixed with these burning substances, sewage containing various toxic substances will be formed. If these sewage is discharged directly into the environment without treatment, it will cause serious pollution to the atmosphere, water bodies and soil. Therefore, when water is used to extinguish the fire after the cable catches fire, the sewage generated must be sampled and tested to assess its degree of harm to the environment.

[0003] However, cable fires do not happen often, and the conditions for sampling sewage are not sufficient. Therefore, a method is needed to simulate the situation of cable fire and then extinguish it to sample sewage. This method is not only safe, but also has high sampling efficiency.

[0004] Application number CN202020949198.9 discloses a fixing frame for cable fire resistance testing, comprising a base, a bracket is provided on the base, a plurality of support rings for placing cables are provided on the bracket, and a cable clamping device is provided on at least two of the support rings; the cable clamping device comprises a round tube, and a clamping screw is provided on the upper part of the round tube, which passes through the side wall of the round tube and is threadedly connected to the round tube; by providing a fixing frame for cable fire resistance testing, the level of the cable can be ensured and the cable can be clamped.

[0005] The number of cables placed in the above patent is limited and the clamping method is relatively cumbersome; in addition, in order to simulate the burning and carbonization of the cable in an actual open flame, it is necessary to energize both ends of the tested cable and then burn it. The traditional energization is done by manually connecting the cable cores using screws and electrode plates, which makes cable loading and unloading time-consuming and troublesome, and makes subsequent sewage sampling troublesome and inconvenient.

[0048] See also Figure 1-Figure 11 As shown, the present invention provides a sewage detection method for extinguishing a burning cable, comprising the following steps:

[0049] S1. First, cut the ends of several cable bodies 130, and then insert them one by one between each pair of bayonet holes 212 of two rotating disks 210;

[0050] S2, rotating the rotating disk 210 to rotate one of the cable bodies 130 to the top, and at the same time, the linkage block 214 below the cable body 130 squeezes the toggle member 340 to drive the power-on sleeve 330 to slide toward the cable body 130 and sleeve and fit to connect the power;

[0052] S4, after the test time of the cable body 130 in S3 is over, continue to rotate the turntable 210 to turn the next adjacent cable body 130 to the top, and then the power is turned on;

[0053] S5, continue to burn the plurality of cable bodies 130 in sequence according to the operations of S2-S4 until carbonization occurs;

[0054] S6. Then, several cable bodies 130 are removed for extinguishing, and sewage is collected for testing of water quality. Chemical testing is performed using total organic carbon analysis, and material composition and material concentration are determined using spectroscopy. Total organic carbon analysis is used to determine the content of total organic carbon in water or soil. Spectral analysis includes ultraviolet-visible spectroscopy, fluorescence spectroscopy, infrared spectroscopy, nuclear magnetic resonance spectroscopy, and Raman spectroscopy.

[0055] Total organic carbon analysis is one of the important indicators for evaluating the degree of organic pollution in water and soil.

The interior of the power supply sleeve 330 is divided into a plurality of cavities at equal intervals in a ring shape, and each cavity is sleeved with a copper sleeve 331, so that the cable body 130 is conductive.

[0067] The number of cavities inside the power-carrying sleeve 330 and the number of battery cells in the power-carrying cable 310 are matched and replaced according to the number of battery cells in the cable body 130, so that each battery cell of the cable body 130 is connected to the positive and negative ends of the power-carrying cable 310, thereby forming a power-carrying circuit, thereby simulating the fire resistance of the cable body 130 when encountering open flames in actual use.

[0068] Specifically, the toggle member 340 includes a ball sleeve and a sliding rod 341 sleeved therein. In order to smoothly slide and contact with the linkage block 214, the ball shell of the ball sleeve squeezes the toggle member 340 downward to drive the power sleeve 330 to slide toward the cable body 130 and match the sleeve to conduct electricity.
