This invention provides an outdoor energy storage battery cabinet, relating to the field of energy storage equipment technology. It includes a housing, a first elastic rope, a second elastic rope, and a tensioning assembly. The housing has a receiving cavity for accommodating the energy storage battery and a heat dissipation window communicating with the receiving cavity. Both the first and second elastic ropes are slidably connected to the housing and are retractable. The first and second elastic ropes are arranged crosswise at the heat dissipation window to divide the window into multiple heat dissipation holes. The tensioning assembly is connected to at least one of the first and second elastic ropes and can push and pull the first and / or second elastic ropes to extend or shorten them, thereby adjusting the diameter of the heat dissipation holes. This invention can dynamically adjust the heat dissipation capacity according to the battery's operating state and environmental conditions, solving the technical defects of fixed heat dissipation schemes such as unadjustable heat dissipation and poor environmental adaptability, thereby improving the operational safety and environmental adaptability of the energy storage system.

The invention discloses an imaging lens module which comprises an imaging lens, a variable light through hole module, a first spacer and a second spacer. The variable light through hole module is arranged between an object side lens group and an image side lens group of the imaging lens and comprises a light shielding sheet group, a plurality of fixed shafts, a movable piece and a driving mechanism. At least two anti-dazzling screens of the anti-dazzling screen group are stacked around the optical axis and form a light through hole. And the fixed shaft and the movable piece are respectively arranged corresponding to the anti-dazzling screen group. The driving mechanism is used for driving the movable piece to rotate in the circumferential direction, so that the anti-dazzling screen set can move relative to the fixed shaft, and the aperture size of the light through hole is adjusted. The fixing shaft is arranged on the first distance piece. The second spacer and the first spacer are correspondingly arranged and are coupled with each other to form an internal space for accommodating the variable light through hole module. The second spacer carries the object-side lens group and is in physical contact therewith. The invention further discloses a camera module with the imaging lens module and an electronic device with the camera module.

The utility model relates to the technical field of construction engineering, and discloses a lime pay-off device based on municipal construction engineering, which comprises a base, the upper surface of the base is fixedly connected with a charging barrel, the lower surface of the charging barrel is fixedly connected with a discharging pipe, one end of the discharging pipe penetrates through the surface of the base and extends to the outside, and the other end of the discharging pipe is fixedly connected with the base. The lower portion of the outer wall of the discharging pipe is rotationally connected with a fixing disc, and a sliding groove is formed in the surface of the fixing disc in the circumferential direction. The motor I is started to drive the rotating shaft to rotate, the rotating shaft drives the gear to rotate, the gear drives the gear ring to rotate, and under the matched use of the sliding groove, the sliding rod can slide in the sliding groove, the sliding rod drives the adjusting block to move, and the adjusting block slides on the lower surface of the discharging pipe, so that the adjusting block can rotate outwards at the same time to be opened; and the aperture size of the discharging pipe can be adjusted, so that the line width size of a white line can be adjusted, and the problem of resource waste is avoided.

This utility model provides a high-sealing junction box, belonging to the technical field of junction boxes. It includes a base plate, with two symmetrically fixed vertical sidewalls on both sides of the front of the base plate. A C-shaped frame is horizontally slidably installed between the two sidewalls, forming a box structure. Circular perforations are installed in the middle of the upper and lower ends of the C-shaped frame. Several arc-shaped blades are movably installed in the center of the perforations. A limiting bracket for retracting the arc-shaped blades is rotatably installed in the center of the perforations, forming a camera aperture structure. A sealing sleeve for fitting onto the cable is fitted at the opening of the perforations. The arc-shaped blades retract and abut against the outer edge of the sealing sleeve to form a seal. This utility model is flexible and convenient to use, can adapt to the sealing installation of cables of different specifications, and has good overall performance.

The utility model relates to the technical field of plastic recycling, and particularly discloses a plastic screening and recycling device which comprises a discharging frame, a vibration motor, two sets of screening frames and screening plates arranged in the screening frames, the bottoms of the screening plates are connected with baffles in a sliding mode, and adjusting assemblies used for adjusting the baffles to slide are arranged on the screening frames. By arranging the sieve plate, the baffle, the fixing block, the threaded rod, the sliding piece and the limiting piece, when the threaded rod is rotated, the fixing block drives the baffle to translate in the guide direction of the sliding piece, meanwhile, the limiting piece ensures the rotation positioning accuracy of the threaded rod, and by adjusting the relative position of the baffle and the sieve plate, the hole diameters of the baffle and the sieve plate are staggered; by means of the design, accurate adjustment can be conducted according to the processing requirements of plastic particles with different particle sizes, the adaptability of the production process is guaranteed, and the production efficiency and practicability are remarkably improved.
