Embodiment 1

[0030] A method for preparing a corrosion-resistant and heat-dissipating material with a micro-arc oxidation / graphene composite coating, comprising the following steps:

[0031] Step 1. Select Mg-Zn-Ca-Sm-Be alloy as the substrate, polish the surface with 600, 800, 1000 and 1200# sandpaper in turn, and then use acetone and alcohol to ultrasonically clean it for 15 minutes;

[0032] Step 2, with NaAlO 2 :2g / L,NaOH:3g / L,nano-Al 2 o 3 :lg / L and sodium dodecylbenzenesulfonate SDBS:lg / L ratio

[0033] Example mixing, mechanical stirring, prepared nano-Al 2 o 3 Modified micro-arc oxidation electrolyte;

[0034] Step 3. Use the stainless steel plate of the electrolytic cell as the cathode, and the Mg-Zn-Ca-Sm-Be alloy as the anode, use the micro-arc oxidation electrolyte prepared in the above steps, and then use the pulse power supply as the power supply, and apply The voltage of 300V, and under the condition of voltage of 300V, temperature lower than 50℃ and stirring, the oxid...

Embodiment 2

[0042] Step 2, with NaAlO 2 :1g / L,NaOH:3g / L,nano-Al 2 o 3 :lg / L and sodium dodecylbenzenesulfonate SDBS:lg / L ratio

[0043] Example mixing, mechanical stirring, prepared nano-Al 2 o 3 Modified micro-arc oxidation electrolyte; other preparations are the same as in Example 1.

Embodiment 3

[0045] Step 2, with NaAlO 2 :2g / L,NaOH:3g / L,nano-Al 2 o 3 :lg / L and sodium dodecylbenzenesulfonate SDBS:lg / L ratio

[0046] Example mixing, mechanical stirring, prepared nano-Al 2 o 3 Modified micro-arc oxidation electrolyte; other preparations are the same as in Example 1.

Abstract

The invention discloses a mining flame-proof type searchlight which comprises a light cap. The outer wall of one side of the light cap is fixedly connected with a motor through a bolt, and one end ofthe motor is rotationally connected with a gear through a rotary shaft, and the outer wall of the other side of the light cap is in sliding connection with an inner gear ring through a sliding block and a sliding groove. The inner gear ring and a gear are in engaged connection through gear teeth, and an arc-shaped brush rod is embedded into the outer wall of the side, away from the motor, of the inner gear ring. According to the mining flame-proof type searchlight, through engaged connection of the gear and the inner gear ring, the motor drives the gear to rotate through the rotary shaft, theinner gear ring rotates on the light cap, the arc-shaped brush rod rotates along with rotation of the inner gear ring, and dust and water drops on a light shape are brushed off through the arc-shapedbrush rod. On one hand, the situation that the dust is accumulated to influence transmission of light, the radiation effect of the light is reduced, the clarity of the view field in a mineral drive isseriously influenced, and safety accidents are likely to be caused is avoided; and on the other hand, the situation that water vapor in the mineral drive is condensed on the light cover, the illuminating effect is influenced is avoided.

Description

technical field [0001] The invention belongs to the technical field of searchlights, and in particular relates to a mine-used explosion-proof searchlight. Background technique [0002] A searchlight is a device with a powerful light source and a concave mirror that can concentrate and project the light in a specific direction. It is used for long-distance lighting and search purposes. In order to obtain greater light intensity, considering the size, weight and easy operation of the device, most searchlights are equipped with tripods or movable vehicles, and large searchlights even have special trucks as vehicles. [0003] However, the dust and water vapor in the mine tunnel will be adsorbed and accumulated on the lampshade of the searchlight during the use of the existing flameproof searchlight in the market, which will affect the penetration rate of the light and reduce the clarity of lighting and vision. In addition, the existing searchlight The irradiation angle of the s...
