This utility model discloses a photovoltaic-thermal module for an evaporator, including a photovoltaic module, a heat absorber plate, a heat absorption channel, and a frame. A junction box is provided inside the photovoltaic module. The heat absorber plate is fixedly connected to the back of the photovoltaic module, and the heat absorption channel is fixedly connected to the heat absorber plate. Refrigerant circulates within the heat absorption channel. The heat absorption channel includes a manifold and branch pipes. The manifold has a closed design at both ends and is connected to a connecting pipe. The branch pipes are internally threaded thin tubes with a diameter of 3-10 mm. Both ends of the branch pipes are connected to the manifold, and one or more semi-circular bends are provided along the length of the same branch pipe. Using this photovoltaic-thermal module significantly reduces the risk of photovoltaic panel deformation and microcracks in the solar cells, simplifies the manufacturing process, reduces costs, and optimizes heat exchange efficiency.

The utility model discloses a cutting device for power cable processing, which comprises a working table, a first chute is arranged at the top of the working table in a penetrating manner, a driving assembly is arranged at the bottom of the working table, a first screw rod is arranged at the bottom of the working table through the driving assembly, and the surface of the first screw rod is rotatably connected with a fixing plate. The fixing plate is fixedly connected with the workbench, the surface of the first screw rod is in threaded connection with a first moving plate, a clamping assembly is arranged at the top of the first moving plate, an adjusting assembly is arranged at the top of the workbench, a moving frame is arranged at the top of the workbench through the adjusting assembly, and a lifting assembly is arranged at the top of the moving frame. A second moving plate is arranged in the moving frame through a lifting assembly, and a cutting assembly is arranged on the second moving plate. And the cable is cut after being tightened, so that the cable can be kept in a linear state, and the length measurement error caused by bending or loosening of the cable in the cutting process is avoided.

The utility model relates to the technical field of batteries, and discloses a separated assembled pole structure which comprises a top cover plate, a pole upper section and a pole lower section, and the pole upper section and the pole lower section are formed in a split manner; the post terminal lower section penetrates through the top cover plate and is provided with an upper part extending above the top cover plate, the post terminal upper section is connected with the upper part, the post terminal lower section is provided with a lower part located below the top cover plate, and the post terminal upper section and the post terminal lower section are connected to form a post terminal; the separated assembled pole structure provided by the utility model has the following advantages: 1) the pole upper sections and the pole lower sections are formed in a split manner and are connected to form the pole, so that the assembling technology is simple, the assembling efficiency is high, and the surface is not damaged; (2) the quality of the pole is easier to guarantee; 3) the poles are assembled in a separated manner, the error-tolerant rate is higher, and when the over-current capability needs to be changed, only the width size or the length size of the upper sections of the poles needs to be changed; and 4) the polar column structure adopts a single polar column arrangement, so that the flatness of the polar column is easier to control.

The application discloses a prefabricated beam shared steel pedestal based on a standardized segment combination and a construction method, and relates to the technical field of bridge engineering prefabricated beam production. The application comprises a foundation support, a main frame and a top surface support. The foundation support is installed on a concrete cushion layer. The main frame is installed on the foundation support. The top surface support is installed on the main frame. The main frame comprises a T-beam pedestal and a box girder pedestal. The T-beam pedestal is connected with the box girder pedestal through flanges. The T-beam pedestal is used as a steel pedestal for T-beam prefabrication. The T-beam pedestal and the box girder pedestal are combined to be used as a steel pedestal for box girder prefabrication. The main frame is arranged to be the T-beam pedestal that can be used for T-beam prefabrication alone and the box girder pedestal that can be combined with the T-beam pedestal for box girder prefabrication. Therefore, the same set of steel pedestal systems can meet the prefabrication requirements of both T-beams and box girders, the versatility and adaptability of the pedestal are improved significantly, and the need for setting special pedestals for different beam types is reduced.
