The invention discloses a full-process management platform suitable for welding training examination, relates to the technical field of welding examination training, and solves the technical problems that in the prior art, data acquisition and analysis cannot be carried out on a welding process, and score addition and score reduction cannot be carried out according to whole-process analysis. Specifically, a welding machine operation analysis unit analyzes welding machine operation regulation and control in the checking process; the process evaluation and analysis unit performs welding process evaluation on an examiner, collects a welding depth parameter and a welding deviation parameter, generates a process evaluation and analysis abnormal signal or a process evaluation and analysis normal signal according to parameter analysis, and sends the signal to the full-process management platform; and the full-process management platform performs score addition and score subtraction on the assessor according to the type of the received signal, and performs score setting according to the corresponding process execution degree.

The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device for environmental protection engineering. Comprising a shell, a first cushion block and a second cushion block are fixedly connected in the shell, a first cavity and a second cavity are formed in the shell, the first cushion block is located in the first cavity, the second cushion block is located in the second cavity, and the first cavity is communicated with the second cavity through a connecting hole; the bubble generator is arranged on the shell, and release holes are formed in the bubble generator; the filtering plate is fixedly connected to the shell, and filtering holes are formed in the filtering plate. Impurities are prevented from getting close to release holes of the bubble generator through the filter plate, so that the situation that the impurities are deposited on the lower side of the bubble generator, microbubbles cannot be attached to the impurities sinking to the bottom when moving upwards, the impurities are gradually accumulated in the second cavity, and then the release holes of the bubble generator are blocked is avoided. And the use efficiency of the air flotation machine is influenced.

The utility model discloses a cooling tower water replenishing system which comprises a cooling tower, a condensate pipe, a first water replenishing pump, a clear water tank and a recycling pipe, and the two ends of the recycling pipe are connected to the bottom of the condensate pipe and the cooling tower respectively and communicated with the condensate pipe and a water collecting disc of the cooling tower. And an inlet and an outlet of the first make-up pump are respectively connected to the clear water tank and the cooling tower and are communicated with the clear water tank and a water collecting tray of the cooling tower. According to the water replenishing system of the cooling tower, the originally discarded condensate water can be used as one of water replenishing sources of the cooling tower, so that the use amount of tap water is reduced, a large amount of water resources are saved, and the electric energy for lifting and discharging the condensate water and the electric energy for lifting and supplying the tap water are saved; and in summer, the temperature of condensate water reaching the water collecting tray is slightly lower than the water replenishing temperature of tap water, so that adverse effects on the efficiency of the refrigerating unit are avoided.

The utility model discloses a kind of ultrafiltration water treatment devices, including frame and the filter being arranged in its inside, the filter is equipped with several groups, the lower end of each group filter is communicated with inlet pipe, the upper end of each group filter is communicated with outlet pipe, the frame is opposite with the inlet pipe and is equipped with flow pipe, transfer pipe is arranged between the inlet pipe and the flow pipe, filter screen is arranged in the transfer pipe, the inlet pipe and the flow pipe opposite end on each other are communicated with branch pipe by reversing valve, and two groups of branch pipes are oppositely arranged, and two groups of branch pipes are also arranged with transfer pipe with filter screen between, filter screen in filter needs to be replaced periodically in traditional, located in filter inside, personnel replacement is time-consuming and laborious, not enough convenient, also need to stop overall filtration work in replacement process, increase overall maintenance time, affect overall filtration efficiency, the utility model can avoid replacing filter screen when affecting overall filtration effect.

The invention relates to a light-transmitting film photovoltaic module and a preparation method thereof. The light-transmitting film photovoltaic module comprises a glass substrate, a transparent front electrode layer, a battery layer, a back contact layer and a transparent back electrode layer which are stacked in sequence. Each dead zone comprises a P1 laser groove, a P2 laser groove and a P3 laser groove; the P1 laser groove penetrates through the transparent front electrode layer, the battery layer and the back contact layer; the P2 laser groove penetrates through the battery layer and the back contact layer; the P3 laser groove penetrates through the battery layer, the back contact layer and the transparent back electrode layer; wherein the P1 laser groove, the P2 laser groove and the P3 laser groove are all light-transmitting areas; the distance between the P1 laser groove and the P2 laser groove is 0; and the distance between the P2 laser groove and the P3 laser groove is 0. According to the light-transmitting film photovoltaic module provided by the invention, the light-transmitting uniformity and the light-transmitting effect of the module can be improved, the appearance yield can be improved, the process time of the module can be shortened, the process cost can be reduced, and the efficiency of the module can be improved.
