5results about How to "Smooth maintenance" patented technology

The present application belongs to the technical field of photovoltaic support deformation detection, and particularly relates to a detection device for preventing photovoltaic support deformation, which comprises a base, a sliding groove column is fixedly connected to one side of the upper end face of the base, a detection box is slidingly connected to the sliding groove of the sliding groove column, and a track display mechanism for recording the deformation position number and deformation degree of the photovoltaic support is further arranged on the detection box. The deformation position of the photovoltaic support can be marked by means of attaching adhesive tape through the attaching mechanism, and the deformation position of the photovoltaic support can be directly observed during subsequent maintenance and other work on the photovoltaic support, so that the process of searching for the deformation position of the photovoltaic support again by personnel is saved, time and labor are saved, and the subsequent maintenance and other work on the photovoltaic support can be smoothly performed.

This invention discloses a wall tie for non-removable external scaffolding, relating to the field of building technology. The wall tie includes a wall-connecting plate in a herringbone shape. A fixing block is fixedly connected to the left side of the wall-connecting plate. Two symmetrical support frames are arranged on the side of the fixing block away from the wall-connecting plate. The two support frames have identical structures and are U-shaped. This wall tie for non-removable external scaffolding avoids safety hazards through installation and does not hinder subsequent construction processes. It effectively prevents workers from removing the wall tie during later wall construction and kitchen / bathroom waterproofing, ensuring a sufficient number and reasonable distribution of wall ties. It also eliminates the common quality problem of sealing wall openings. Traditional wall tie structures require pre-reserved openings during wall construction, leading to high costs and poor results in sealing these openings later, and even causing wall leakage.

The utility model relates to a down -the -hole impactor maintenance technical field especially relates to a kind of fixing device for down -the -hole impactor maintenance.A kind of fixing device for down -the -hole impactor maintenance, including bottom plate etc., two risers are fixedly connected with bottom plate top interval, the upper side of two risers is rotatably provided with short shaft, two short shafts are fixedly connected with U-shaped beam between, two reinforcing plates are fixedly connected with U-shaped beam middle interval, still including clamping assembly, pushing assembly and limiting component.The utility model can be completed to the clamping fixation of impactor simultaneously by rotating long shaft, save time and effort, reduce the degree of operation complexity, improve maintenance efficiency, applicability aspect, because adjacent clamping plate spacing is adjustable, can adapt to different diameter model impactor, in addition, with angle adjusting function, can rotate U-shaped beam adjustment impactor inclination angle, it is convenient to observe and maintain, and angle limit can be realized by block and gear engagement, guarantee maintenance smoothly.

The invention relates to the technical field of ship distribution boxes, in particular to a ship cabin low-voltage direct-current explosion-proof distribution box which comprises a main box body, a mounting chamber used for mounting an electric switch is arranged in the main box body, a handle is fixedly mounted on the main box body, and a supporting device is arranged in the main box body. A supporting device is arranged in the main box body, a supporting rod used for supporting the hand of an operator for operating the electric appliance switch is arranged in the supporting device, an operating device is arranged in the main box body, an operating rod which moves along the supporting rod and is used for operating the electric appliance switch is arranged in the operating device, and the supporting device comprises a mounting cavity formed in the main box body; and two sliding grooves are symmetrically formed in the side wall of the mounting cavity. The ship power distribution cabinet solves the problem that an existing ship power distribution cabinet is difficult to provide stable support for the hand of an operator used for operating an electric appliance switch, so that the risk that the operator mistakenly touches the electric appliance switch due to ship shaking is reduced.

This utility model belongs to the field of kelp technology, specifically disclosing a rapid draining device for salted kelp based on centrifugal dehydration. It includes a support frame, a box fixedly connected to the top of the support frame, a guide plate fixedly connected inside the box, a connecting shaft rotatably connected inside the guide plate, a placement frame fixedly connected to the top of the connecting shaft, a centrifugal drum housed inside the placement frame, a cleaning plate fixedly connected to the outer surface of the connecting shaft, and a brush at the bottom of the cleaning plate. Mesh holes are provided in the centrifugal drum, placement frame, and guide plate. This rapid draining device for salted kelp based on centrifugal dehydration is operated by a worker who starts a motor, causing the motor to rotate the connecting shaft. The connecting shaft, through the placement frame, rotates the centrifugal drum, causing the centrifugal drum to spin-dry the kelp using centrifugal force. The water drained from the kelp is collected and discharged through a drain pipe.
