The utility model relates to the field of experimental equipment, and discloses a device for simplifying the counting of seed germination experiments, which comprises a culture dish. A top cover is arranged on the top of the culture dish, a counting paper is arranged on the upper part of the top cover, a culture rack is placed in the middle of the culture dish, a filter paper is arranged in the middle of the culture rack, a positioning grid is arranged on the upper surface of the filter paper, a plurality of labels are arranged on the upper surface of the filter paper, a first arrow is arranged at the front part of the top surface of the filter paper, a counting grid is arranged on the upper surface of the counting paper, a second arrow is arranged at the front side of the top surface of the counting paper, and the size diameter of the counting paper is the same as that of the filter paper. In the utility model, through the mutual cooperation among components such as the culture dish, the top cover, the filter paper and the counting paper, the staff only needs to count the newly germinated seeds every day, which can greatly reduce the working time and workload and is more practical.

The utility model relates to the technical field of electric power engineering construction discloses a kind of line laying device for electric power construction, including pedestal, the tensioning mechanism includes two support columns, the bottom of two The support column is fixedly connected at the top of pedestal, and the external left side of one of the support column is fixedly connected with connecting thin rod, and the external of another The support column is fixedly connected with support rod, the external sliding connection of rotating shaft has support sleeve, the external of support sleeve is fixedly connected with multiple connecting plates.In the utility model, since the right side of each connecting card plate is buckled outside the turntable, since connecting card plate and connecting plate are rotatably connected by multiple connecting blocks, connecting card plate makes centripetal and centrifugal motion on turntable in the movement process of support sleeve, complete the support barrel of adaptation different radius, so that the complete storage effect of cable of different length and width is realized, and the internal stress of cable is reduced, and the service life of cable is prolonged.

This invention relates to a split-type sliding device and its method for translating heavy-duty silos. A chute is laid on a lower track beam; a sliding box is installed on the chute and can slide along it; a vertical lifting jack is installed inside the sliding box; after pulling the sliding box to the lifting point below the silo wall, the vertical lifting jack and the vertical load control box are connected; the vertical load control box is activated to complete the silo lifting and replacement and remove temporary supports; a horizontal traction jack and the traction load control box are installed; the horizontal traction device is connected to the anchor block at the end of the sliding box via the connecting steel bar, and the connecting steel bar passes through the concrete reaction pier and is anchored to the horizontal traction jack; the traction load control box is activated to realize the silo translation. A limiting device is set between the sliding box and the chute to prevent large swaying of the heavy-duty silo during translation. Connecting bolt anchor blocks are set at both the front and rear of the sliding box to ensure that multiple sliding boxes can be connected in series on the same sliding track. This invention uses a single-point support slide box and lightweight matching slide rails, which facilitates on-site implementation in areas with limited installation space and features a low coefficient of friction, reducing translational traction force and improving translational construction efficiency.

The utility model belongs to underwater cable technical field discloses a kind of bending-resistant underwater cables, including conductor, insulating layer, sheath layer and protective layer, conductor is formed by multiple copper wire strands multilayer complex twisting, and the complex twisting direction of each layer copper wire strand is same, copper wire strand is formed by multiple tinned copper wire bundle twisting, insulating layer is coated in the outer periphery of conductor, sheath layer is coated in the outer periphery of insulating layer, protective layer is coated in the outer periphery of sheath layer, the material of protective layer is polyether polyurethane elastomer, shore hardness is (A80-D70).The bending-resistant underwater cable provided by the utility model has pressure resistance and flexibility simultaneously, when bending laying, it can be quickly laid, reduce the degree of difficulty of laying, simultaneously, it can effectively reduce the degree of stress concentration at bending, the risk of fracture at bending is low, and it can stably transmit electric energy.

This utility model discloses an easily adjustable double-wall corrugated pipe. A connecting adjustment assembly is provided at the end of the corrugated pipe. A metal flexible tube is provided on one side of a multi-hole end ring. Connecting studs are uniformly welded to the outside of the connecting ring, and a connecting nut is threaded into the center of the connecting stud. A rotating ball is rotatably embedded inside the inner rotating cylinder. Two lead screws located on the same straight line are respectively threaded to both ends of the internally threaded pipe. A connecting protection assembly is installed on the outside. This utility model adjusts the distance between the lead screws at both ends of the internally threaded pipe, and continues to adjust the remaining internally threaded pipes. The adjustment range of each internally threaded pipe is different, thus causing the rotating ball at the end of the lead screw to rotate at different ranges within the inner rotating cylinder. The metal flexible tube bends, completing the operation of adjusting the angle of the double-wall corrugated pipe. This makes the laying of the double-wall corrugated pipe more convenient and prevents the problem of double-wall corrugated pipe breakage due to forced bending, greatly improving convenience.
