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

Abstract

The invention discloses a mine explosion-proof searchlight, which includes a lamp cap. A motor is fixedly connected to one side of the outer wall of the lamp cap through bolts. One end of the motor is connected to a gear through a rotating shaft. One side of the outer wall of the lamp cap is connected to the gear. An internal gear ring is slidably connected to the top of the internal gear ring through a slider and a chute. The internal gear ring and the gear are connected through gear teeth, and an arc-shaped brush rod is embedded in the outer wall of the side of the internal gear ring away from the motor. The present invention uses the gear It is meshed with the internal gear ring. The motor drives the gear to rotate through the rotating shaft. The internal gear ring rotates on the lamp head. The arc-shaped brush rod rotates with the rotation of the internal gear ring. The arc-shaped brush rod brushes off dust and water droplets on the lampshade. , on the one hand, it prevents dust accumulation from affecting the penetration of light and reduces the effect of light illumination, which seriously affects the clarity of vision in the mine tunnel and easily causes safety accidents. On the other hand, it prevents water vapor in the mine tunnel from condensing on the lampshade, affecting the lighting effects.

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...
