The application provides a water lens heater for warming and heat preservation of a mariculture pond and a use method, and relates to the technical field of seawater heating. The heater comprises a water lens unit and at least one heat preservation unit, the water lens unit and the heat preservation unit form a stacked structure distributed in an up-down mode, the water lens unit is located below the heater, and the heat preservation unit is stacked above the water lens unit; a water injection cavity for water injection is formed in the water lens unit, and an air cavity for air injection is formed in the heat preservation unit; the water lens unit and the heat preservation unit are both made of a light-transmitting film. The heater can effectively shorten the warming period of the mariculture pond through the synergistic effect of the three mechanisms of heat locking through the greenhouse effect, light concentration and efficiency increase through the lens, and multi-layer air heat insulation, can raise low-temperature seawater to a suitable temperature for breeding in several hours or 1-2 days, and greatly improves fattening efficiency and production rhythm.

The invention relates to the technical field of mine ventilation, and provides a mine ventilation device facilitating pipeline arrangement, which comprises a barrel, a rotating rod is rotatably connected in the barrel, the rotating rod is driven by a driving assembly to rotate, and an exhaust fan mounted on the inner wall of the barrel is driven by the rotating rod to perform exhaust work; and fresh air is conveyed into the first connecting pipe, the rear side of the barrel is fixedly connected with a dust blocking plate used for blocking dust, and a cleaning brush used for cleaning dust accumulated on the surface of the dust blocking plate is arranged on the rear side of the dust blocking plate. Due to the modular split type design of the pipeline part, the pipeline can be laid more flexibly, the problem that the structure is too short or too long is reduced, splicing or cutting off is not needed, the integrity of the pipeline is guaranteed, the reusability is improved, when a certain position of the pipeline part is damaged, only the corresponding part needs to be replaced and maintained, and the cost is reduced. The influence on other pipelines is eliminated, and the pipeline replacement and maintenance cost is reduced.

The utility model relates to mining air purification and dust removal equipment which comprises a water storage tank, a water pump, a water supply pipeline and a plurality of spraying and dust falling mechanisms, the water pump is installed on the side wall of the water storage tank and connected with the spraying and dust falling mechanisms through the water supply pipeline, and each spraying and dust falling mechanism comprises a supporting seat. A plurality of supporting legs are installed on the bottom side of the supporting base, and a rotating disc is rotationally installed on the top side of the supporting base. According to the on-site dust falling and suppression requirements, a water supply pipeline and a spraying dust falling mechanism can be flexibly laid, when rocks are blasted or stones are loaded and transported in a mine, a water pump is started to achieve fixed-point spraying dust falling, operation is easy and convenient, remote control is achieved, and safety and reliability are achieved; and therefore, 360-degree dead-corner-free spraying and dust falling are realized, the wide spraying range is ensured, and the dust falling effect is improved.

The invention relates to the technical field of pipeline laying, and discloses a pipeline laying device for a power grid distribution network and a pipeline bending method for the power grid distribution network. The pipeline laying device for the power grid distribution network comprises a bottom plate and a flexible insulation wire fixing plate located above the bottom plate, and one end of the flexible insulation wire fixing plate is fixedly connected with the bottom plate through a first fixing piece; the heating assembly is arranged on the flexible insulation wire fixing plate and makes contact with the outer wall of the pipeline, and the heating assembly is selectively connected with the power source; the driving mechanism is mounted on the bottom plate and is connected with one end, far away from the first fixing piece, of the flexible insulating wire fixing plate; the locking piece is positioned above the bottom plate; when the heating assembly is connected with the power source, the driving mechanism can drive the flexible insulation wire fixing plate to drive the pipeline to be bent, and the bent pipeline is fixed to the bottom plate through the locking piece. According to the pipeline laying device for the power grid distribution network, the pipeline can be bent after being preheated and softened, so that the pipeline is prevented from being broken due to stress concentration at the corner, and the safety and reliability of pipeline laying are improved.
