[0024] Example 1

[0025] Reference Figure 1 , which is the first embodiment of the present invention, provides a method for preventing small animals from invading a cable trench in a substation, characterized in that:

[0026] S1: Through the monitoring module 100, including a box 101, a control module 102 fixedly connected to the inside of the box 101, an image monitoring module 103 connected to the input end of the control module 102, a gas monitoring module 104 connected to the input end of the control module 102, an infrared sensing module 105 connected to the input end of the control module 102, a power module 106 fixedly connected to the inside of the box 101, the power module 106 electrically connected to the control module 102, and a wireless communication module 107 fixedly connected to the inside of the control module 102;

[0027] The driving module 200 includes a water tank module 201 fixedly connected to the inside of the box body 101 , a sound playing module 202 fixedly connected to the water tank module 201 , and a laser module 203 fixedly connected to the inner wall of the water tank module 201 .

[0028] The gas monitoring module 104 includes a nano material coating 104a, which includes nano titanium dioxide 104a-a, nano zinc oxide 104a-b and nano silicon dioxide 104a-c. The nano titanium dioxide 104a-a has a particle size of 20 nanometers.

[0029] Furthermore, the nano material coating 104a comprises nano titanium dioxide 104a-a 80%, nano zinc oxide 104a-b 10% and nano silicon dioxide 104a-c 10%.

[0030] Furthermore, the nano material coating 104a is applied to the detection layer of the sensor inside the gas monitoring module 104 and is covered with a porous silicon film protection layer.

[0031] Preferably, the particle size is selected to be 20 nanometers, which can provide a large surface area and maintain the stability of the particles to a certain extent to avoid agglomeration. Nano zinc oxide has a high surface area and good gas adsorption performance, nano silicon dioxide has good stability and heat resistance, and nano titanium dioxide has a high surface area, which can enhance the gas adsorption capacity. Photocatalytic performance: Nano titanium dioxide has excellent photocatalytic performance, can decompose harmful gases under light conditions, and improve detection sensitivity and response speed. Stability: Nano titanium dioxide has good chemical stability and heat resistance, and can maintain stable detection performance under high temperature and harsh environment. By selecting and optimizing a functional material in the nanomaterial coating formula, nano titanium dioxide is determined to be the optimal implementation method, which solves the contradiction between sensitivity and stability in the prior art and significantly improves the overall performance of gas detection. This choice is not only not easy to be thought of by technicians in this field, but also shows outstanding performance advantages in practical applications, proving its technical innovation and practicality.

[0032] S2: After the image monitoring module 103 captures the small animal, the image is input to the control module 102 through the input terminal.

[0033] S3: After the infrared sensing module 105 senses the small animal, the infrared sensing module 105 inputs a signal to the control module 102 through the input terminal.

[0034] S4: The control module 102 sends a signal to the laser module 203 through the output terminal, driving the laser module 203 to emit laser to drive away small animals.

[0035] S5: The control module 102 sends a signal to the water tank module 201 through the output terminal, and the water tank module 201 sprays acetic acid mist to drive away small animals.

[0036] S6: The control module 102 sends a signal to the sound playing module 202 through the output terminal, and the sound playing module 202 emits a pre-recorded sound to drive away small animals.

[0037] Furthermore, the power module 106 is electrically connected to the control module 102 , the image monitoring module 103 , the gas monitoring module 104 , the infrared sensing module 105 , the water tank module 201 , the sound playing module 202 and the laser module 203 .

[0038] Example 2

[0039] Reference Figure 1 , which is the second embodiment of the present invention, provides a method for preventing small animals from invading a cable trench in a substation, characterized in that:

[0040] The gas monitoring module 104 includes a nano material coating 104a, which includes nano titanium dioxide 104a-a, nano zinc oxide 104a-b and nano silicon dioxide 104a-c. The nano titanium dioxide 104a-a has a particle size of 20 nanometers.

[0041] Furthermore, the nano material coating 104a comprises nano titanium dioxide 104a-a 80%, nano zinc oxide 104a-b 10% and nano silicon dioxide 104a-c 10%.

[0042] Furthermore, the nano material coating 104a is applied to the detection layer of the sensor inside the gas monitoring module 104 and is covered with a porous silicon film protection layer.

[0043] Among them, nano zinc oxide has a higher specific surface area and can provide more active sites for the adsorption of gas molecules. Specifically, the structure of nano zinc oxide makes its surface activity higher and its adsorption capacity stronger. Adsorption mechanism: When nano zinc oxide adsorbs gas molecules, it mainly uses two mechanisms: physical adsorption and chemical adsorption. The former depends on van der Waals force, while the latter is related to oxygen vacancies and lattice defects on the surface of zinc oxide. It also has strong photocatalytic activity and can generate electron-hole pairs under ultraviolet light, participating in redox reactions to decompose organic matter and harmful gases.

[0044] Nano-silicon dioxide has extremely high chemical stability and heat resistance, and is not easy to react with other chemicals, ensuring the stability of the coating under various environmental conditions. The nanostructure of nano-silicon dioxide has excellent mechanical strength and crack resistance, and can maintain integrity in coating applications;

[0045] Nano-TiO2: At a particle size of 20 nanometers, the sensitivity reached a maximum of 120% (relative to the benchmark).

[0046] Nano zinc oxide: At 10 nanometer particle size, the sensitivity is 100%, but drops to 70% in high humidity environments.

[0047] Nano-silica: The sensitivity is lower at 80%, but it remains stable in high temperature environments.

[0048] To make the nanomaterial coating 104a, nano titanium dioxide, nano titanium dioxide and nano zinc oxide are proportioned, the materials are weighed, the powders are dissolved or dispersed in a suitable organic solution to form a uniform suspension, and mixed using a mixing device. In order to improve the dispersibility and stability of the nanoparticles, an appropriate amount of surfactant can be added. After mixing, a suitable coating technology is selected, such as dip coating, spray coating, spin coating, etc., to evenly coat the coating precursor on the surface of the gas monitoring module 104. After the coating is applied, it needs to be cured at a temperature of about 45° to 60° for 10min to 15min.

[0049] Comparative Example 1

[0050] The difference between this comparative example and Example 1 is that the polydimethylsiloxane coating is composed of methylsiloxane as its basic constituent unit, usually composed of a plurality of such units connected by silicon-oxygen bonds, which is completely different from the material in the present invention.

[0051] Taking nano-titanium dioxide particle size as a variable, 20 sets of comparative experimental data will cover the sensitivity, response time, stability under different particle sizes and detection performance under different gas concentrations.

[0052] The experimental data table is as follows:

[0053]

[0054]

[0055] The gas monitoring modules prepared in Example 1 and Comparative Example 1 were subjected to wear evaluation tests, and the results are shown in Table 2:

[0056] Table 2: Comparison of wear resistance of gas monitoring modules prepared under different formulations

[0057]

[0058]

[0059] The test method is to place the coated gas monitoring module 104 on the sand surface, and adjust the wind speed to make the sand polish the surface of the gas monitoring module 104. The test time is 24 hours. After 24 hours, observe the cable surface. Each cable is tested 100 times and the average value is taken.

[0060] By selecting and optimizing a functional material in the nanomaterial coating formula, nano-titanium dioxide was determined to be the optimal implementation method, which solved the contradiction between sensitivity and stability in the existing technology, significantly improved the overall performance of gas detection, and demonstrated outstanding performance advantages in practical applications.
