The invention provides a dry-soil-removed reinforced concrete screw pile forming device. The dry-soil-removed reinforced concrete screw pile forming device comprises a steel mould pipe, wherein the steel mould pipe penetrates through a base of a piling machine, and is provided with an external helicoid, a rotating power head is arranged at the upper end of the steel mould pipe, a cross-shaped connector is arranged at the lower part of the steel mould pipe, a steel hoop is welded to the top end of the steel mould pipe, a notch is formed at one end of the steel hoop, and is matched with the cross-shaped connector, clamps are arranged between the steel hoop and a base of the rotating power head, and can be connected with each other to form a whole, and an auxiliary rotating power device is arranged at the middle part of the steel mould pipe. A pile forming method comprises the following steps of: firstly, arranging the steel mould pipe in place, starting the power head to screw the steel mould pipe into a soil layer, starting the auxiliary rotating power device to a designed elevation in the case that the steel mould pipe enters a hard soil layer, completely removing soil in the steel mould pipe, putting a reinforcing cage into the steel mould pipe, grouting and filling concrete into the steel mould pipe, and inversely rotating the power head to check height of the concrete in the steel mould pipe so as to ensure dimension of the external helicoids of the pile until the steel mould pipe gets away from the soil layer, so that a screw pile is formed. The dry-soil-removed reinforced concrete screw pile forming device and the pile forming method provided by the invention have the advantages of high bearing capacity, high pile forming quality, environment friendliness and energy-saving performance, and is particularly applicable to a deep soft soil layer and a flat-bottomed screw pile.

The invention discloses a vacuum low-temperature drying method for bovine bone glue, which comprises the following steps: 1) raw material preparation step: loading the concentrated bovine bone glue extract into a container, wherein the volume of the concentrated bovine bone glue extract is V1, and the container The volume is V2, V1: V2≤20%; 2) vacuum drying step: first the container of step 1) is put into microwave vacuum drying equipment and heated, so that the bovine bone glue extract concentrate is in a low-temperature boiling state; water vapor and The acetic acid vapor is sucked away by a vacuum pump, and the bovine bone glue extract is concentrated and dried to obtain the bovine bone glue. The vacuum low-temperature drying method of the invention has the characteristics of low acetic acid content, low energy consumption, short drying time, high product yield and high production efficiency.

The invention relates to the technical field of football cleaning, in particular to a high-efficiency scrubbing and drying device for footballs used in competitions. The technical problem to be solved by the present invention is that it is difficult to clean the seams of the skin by manual scrubbing, the cleaning effect is poor, and the water consumption is easy to increase. In order to solve the above-mentioned technical problems, the present invention provides a high-efficiency scrubbing and drying device for soccer balls used in competitions. The present invention consists of a coarse cleaning mechanism outside the box and a cleaning mechanism inside the box. The football is initially cleaned by airflow, which facilitates subsequent cleaning. , effectively reduces cleaning water, is more environmentally friendly, improves the frequency and intensity of football activities in the cleaning box, and further improves the effect of rinsing by bumping the football against each other and the cleaning box, and can effectively remove the stains in the seams of its skin Vibrating out, at the same time, it can also remove water by bumping and rolling the football. The wind rough cleaning process is incorporated into the cleaning box, and the high-speed airflow is effectively used to further remove the moisture on the surface of the football.

The invention relates to a breeding wastewater treatment process, which specifically includes the following process: S1. The breeding wastewater is collected into a sediment tank through a sewage pipe, and the solid feces residue is removed through a solid-liquid separator, and the liquid enters a black film biogas tank; S2. The water flow well measures the influent water entering the black film biogas digester, and distributes the water to the black film biogas digester to remove organic matter in the water; S3, the biogas slurry generated by the black film biogas digester is distributed to the algae purification tank through the lift pump, and put into the immobilized algae The reaction group removes nitrogen, phosphorus nutrients, heavy metals and refractory organic matter in the water body; S4, the effluent from the algae purification tank enters the intermediate sedimentation tank, realizes the separation of algae and water according to the action of gravity, and the sediment flows back to the algae purification tank; S5, the intermediate sedimentation tank The effluent water enters the aerated biological tank, and a microbial generator is installed in the tank to rapidly degrade the organic matter and biochemical sludge in the water through the generated microbial flora; S6, the clarified water from the aerated biological tank enters the storage tank.

The present invention provides a sensor cleaning method, a device, an unmanned vehicle for mining, and a readable storage medium, which are applied to the unmanned vehicle for mining. equal to the preset value; when it is determined that the dirt detection value is greater than or equal to the preset value, control the mining unmanned vehicle to decelerate to stop, and detect the current rainfall; The sensor is cleaned by preset cleaning logic corresponding to the rainfall. In the sensor cleaning method of the present invention, after the unmanned mining vehicle detects that the contamination detection value of the sensor reaches the preset value, it can stop driving to perform rainfall detection, and then select the corresponding cleaning logic in combination with the rainfall to clean the sensor, thereby Improve the efficiency of sensor self-cleaning and save cleaning water.

The invention discloses a photovoltaic module self-cleaning system, which belongs to the field of photovoltaic module cleaning. The photovoltaic module self-cleaning system of the present invention comprises a cleaning module arranged at the upper end of the photovoltaic module, a sewage suction module and a control module arranged at the lower end of the photovoltaic module, the sewage suction nozzle of the sewage suction module is connected with the water suction pump through the sewage suction pipe, and A rotating brush is arranged on the upper part of the suction nozzle. The surface of the inclined photovoltaic module is rinsed from top to bottom through the cleaning module with spray flushing function, and the flushing sewage is sucked out through the sewage suction module with active suction function, and at the same time, it cooperates with the rotation of the sewage suction nozzle The brush cleans the bottom, so that the entire photovoltaic module can be cleaned from top to bottom, and effectively prevents the deposition of dust on the bottom of the photovoltaic module, improving the overall cleaning effect of the photovoltaic module.
