5results about How to "For convenience" patented technology

The utility model belongs to the technical field of hydraulic engineering construction, and particularly relates to a hydraulic engineering construction channel side wall supporting device which comprises a bottom plate. A plurality of electric push rods are fixedly connected to the side wall of the bottom plate; the electric push rods are uniformly distributed on the side wall of the bottom plate and have the same structure; the end part of the electric push rod is fixedly connected with a mounting plate; by rotating a first screw rod, an ejector rod can push a sliding block to slide in a guide rail, a connecting arm can be driven to move, so that the angle of the connecting arm can be adjusted, an electric push rod can push a mounting plate to move, supporting plates on the two sides get close to and apply pressure to the side wall of a channel, and the defects that an existing supporting device is usually fixedly arranged and cannot be used for supporting the channel are overcome. The angle of the supporting plate is adjusted by rotating the first screw rod, so that the supporting angle of the supporting plate is inconvenient to adjust, the supporting effect on the side walls of the channels with different inclination angles is difficult, at the moment, the angle of the supporting plate is adjusted by rotating the first screw rod, the supporting effect of the supporting plate on the side walls of the channels with different inclination angles is achieved, and the practicability of the supporting plate is improved.

The utility model belongs to the technical field of manual stop valve, specifically is a kind of manual stop valve, including manual stop valve body;Manual stop valve body lateral wall is equipped with protective shell;The inboard wall of the protective shell is fixedly connected with drive motor;The output end of the drive motor is fixedly connected with fan blade;Drive motor is rotated to produce airflow with fan blade, airflow passes heating wire at this time, using the air flow of guide plate can be drained, it is dispersed, the dry effect when manual stop valve body is used in humid environment is played, reduce the humidity long time adhesion and cause the rust of manual stop valve body, to improve the service life of manual stop valve body, the contact area of airflow and manual stop valve body can be increased simultaneously using flow guide pipe and guide plate, increase drying speed, and also using protective shell can increase the safety of drive motor when using.

The utility model belongs to the technical field of power distribution cabinets, and particularly relates to a power distribution cabinet convenient to maintain, which comprises a power distribution cabinet body. A mounting plate is arranged on the inner side wall of the power distribution cabinet body; the inner side wall of the power distribution cabinet body is fixedly connected with a pair of guide rails; the guide rails are symmetrically arranged on the two sides of the power distribution cabinet body and are of the same structure. By holding and rotating the screw rod, the mounting plate can be gradually moved out of the power distribution cabinet body at the moment, the inner side wall of the power distribution cabinet body can be cleaned through full contact between the cleaning brush and the inner side wall of the power distribution cabinet body, and in the process, the space in the power distribution cabinet body can be reduced to be narrow, so that the power distribution cabinet is convenient to clean. When the power distribution cabinet body is damaged and needs to be maintained, the maintenance process is relatively tedious, and a certain workload is increased, at the moment, the installation plate is moved out of the power distribution cabinet body, so that convenience is brought to maintenance of the lines in the power distribution cabinet body, and the maintenance efficiency is improved. And meanwhile, dust and impurities falling into the power distribution cabinet body can be cleaned through the cleaning brush.

The utility model relates to the technical field of engines, and discloses an upper frame structure of a general type engine installation vehicle, which comprises a winch, the front side of the winch is fixedly connected with a support frame, the left end and the right end of the support frame are fixedly connected with support pieces, and the bottoms of the support pieces are fixedly connected with bearing shafts. And spherical supports are fixedly connected to the left end and the right end of the winch, placing grooves are formed in the spherical supports, and clamping plates are fixedly connected to the inner walls of the placing grooves. The winch is of a box type structure and is installed at the rear end of the frame, the worm gear, the worm and the gear are used for transmission, the transmission ratio of the worm gear to the worm is 60 degrees, and a good self-locking effect is achieved. And the clamping plate at the lower end can clamp the ball head of the electric cylinder, so that the upper frame does not displace in the horizontal direction, and the stability when the connecting assembly is installed and fixed is improved.

The utility model belongs to water treatment technical field, concretely is a kind of industrial wastewater zero discharge concentrated water recycling device, including wastewater treatment equipment ontology;The wastewater treatment equipment ontology lateral wall is fixedly connected with a pair of electric push rod;The electric push rod is symmetrically arranged on the both sides of wastewater treatment equipment ontology and same structure;Start electric push rod, until universal wheel and ground contact and lift wastewater treatment equipment ontology, when equipment moves to target position, control electric push rod shrink, utilize spring rod elastic push fixed seat and move downwards, equipment can be easily moved, need not manual handling, reduce operator's labor intensity, and universal wheel can flexible steering, adapt to complex site moving demand, the combination of spring rod, fixed seat and fixed tooth, can be inserted into ground by fixed tooth and enhance the adhesion of equipment and ground, avoid equipment to shift in the working process, while spring rod can buffer the vibration when equipment runs, improve equipment stability.
