The utility model discloses an ecological vegetation restoration planting frame, which belongs to the technical field of ecological vegetation planting and comprises a frame body, a soil fixing net and a pipeline group. Wherein the frame body is provided with an upward opening, the non-opening surface of the frame body is provided with a channel for water and soil to pass through, the soil fixing net covers the channel, the pipeline group is buried in the frame body, the pipeline group comprises a main pipeline and an auxiliary pipeline, the main pipeline and the auxiliary pipeline are communicated with each other, and a plurality of uniformly distributed vent holes are formed in the main pipeline and the auxiliary pipeline. The utility model has the advantages that the soil fixation net can intercept silt to form preliminary filtration; the pipeline group forms an air gallery positioned in the frame body, so that root systems of plants planted in the planting frame can obtain good ventilation; the two are combined to realize efficient balance of water and soil conservation and root system ventilation.

This utility model discloses a layered tent, relating to the field of tent technology. It includes an inner tent fabric and an outer tent fabric. The bottom of the inner tent fabric is equipped with windproof fixing ropes, and an inflatable support column is added to the outside of the inner tent fabric. The upper end of the inflatable support column has an inflation port, and a Velcro surface is added to the outer side below the inflatable support column. An installation top post is provided at the upper outer end of the inner tent fabric, and the outer tent fabric is distributed above the inner tent fabric. A limiting installation top is added to the top of the outer tent fabric, and a Velcro hook surface is added to the lower inner side of the outer tent fabric. The lower inner end of the outer tent fabric is provided with a nylon base layer, and an antistatic polyester layer is provided above the nylon base layer. A polyester fiber abrasion-resistant layer is provided above the antistatic polyester layer. This layered tent allows for quick and easy installation of the inner and outer layers, reducing manual labor intensity. It is also easy to assemble and disassemble, increasing the overall practicality and efficiency of the layered tent.

The application belongs to the technical field of solar light utilization, and discloses a solar light energy optical fiber leading-in system with fixed lenses; the system comprises a lens mounting module, which is used for fixing and mounting convex lenses on the outer vertical wall surface of a building; and a sun position determining module, which is used for determining the real-time position of the sun through an astronomical algorithm; the application can flexibly select two kinds of focus-pursuing modes according to different situations, so as to ensure that the solar light energy is effectively and quickly led into the input end of the optical fiber, the optimal degree of freedom combination set of the mirror array corresponding to the real-time position of the sun is quickly determined, the fast focus-pursuing is realized, the focal point spots reflected by the mirrors are accurately superimposed on the input end of the optical fiber, and the focal point spot intensity of the input end of the optical fiber is maximized; the fast focus-pursuing of the input end of the optical fiber is also realized, the focus-pursuing time is reduced, the current optical fiber input end position which is not fixed is adjusted, and the solar light can be accurately led into the input end of the optical fiber.

The utility model discloses an explosion-proof antistatic fan, including main part, sealing mechanism, connecting subassembly and antistatic subassembly, the sealing mechanism includes mounting box, spring, push plate, sealing box, positioning frame and fixing piece, connecting subassembly includes external expansion piece, wiring box, plug and connecting line, antistatic subassembly includes bracing frame, contact block and lead, the connecting box includes the external expansion piece, wiring box, plug and connecting line, the antistatic subassembly includes the bracing frame, contact block and lead. Under the mutual cooperation of the above mechanisms, the sealed connection box can effectively prevent external dust, oil mist, moisture and other substances from entering the line connection box, so that electrical elements are prevented from being affected with damp or polluted, the risk of sparks caused by electrical short circuit is reduced, in addition, the contact area between the device and external air is increased, and the service life of the device is prolonged. The fan can dissipate heat more effectively, and faults caused by too high temperature are avoided.
