3results about How to "Less maintenance hassle" patented technology

The utility model relates to the technical field of road cleaning, and discloses a road sweeping device which comprises a water tank, a dust collection fan is fixedly installed on one side of the water tank, a supporting frame is arranged on one side of the water tank, a sweeping motor is fixedly installed at the lower end of the supporting frame, a servo motor is fixedly installed at the upper end of the water tank, and a transmission rod is installed at the output end of the servo motor. According to the technical scheme, the winding reel on the transmission rod can wind the first pull rope and the second pull rope at the same time, the first pull rope drives the supporting frame to rotate upwards, the supporting frame makes contact with the abutting plate, and therefore a worker can conveniently maintain the cleaning motor and the cleaning brush on the supporting frame, and the cleaning efficiency is improved. The trouble that a worker stoops and creeps for maintenance is avoided, in the rolling process of a second pull rope, the second pull rope drives a scraping plate to move leftwards, the scraping plate scrapes dust deposited at the bottom of the water tank, dust is conveniently discharged from a blow-down valve, and the trouble of maintenance of the worker is further saved.

The utility model relates to building steel technology field discloses a kind of corrosion-resistant building steel structure connecting nodes, including support column, the middle part of the outer wall of support column is provided with connecting mechanism, the connecting mechanism includes connecting seat, the outer wall of the periphery of connecting seat is all set with multiple installation clamping groove, the outer wall of the periphery of connecting seat is all clamped with connecting block, the outer wall of connecting block side close to connecting seat is fixedly connected with reinforcing plate, the outer wall of reinforcing plate side close to connecting seat is fixedly connected with multiple installation clamping block, the periphery of connecting mechanism is all provided with positioning mechanism, and the positioning mechanism includes locating slot and mounting plate. In the utility model, the node is provided with connecting mechanism, and is connected by clamping limit and the mode of threaded fixing, so that user can replace the connecting block used for too long or damaged according to needs, so as to reduce the trouble of the node maintenance and improve the service life of node use.

The utility model relates to the field of sewage treatment, and discloses an oil separation and slag removal device which comprises a base, one side of the upper surface of the base is fixedly connected with a bottom tank body, the upper end of the outer wall of the bottom tank body is fixedly connected with a first flange, and the periphery of the upper surface of the bottom tank body is fixedly connected with a first sealing clamping block; an upper tank body is fixedly connected to the upper surface of the bottom tank body, a second flange is fixedly connected to the lower end of the outer wall of the upper tank body, and a first sealing clamping groove is formed in the periphery of the lower surface of the upper tank body. Compared with most traditional oil separation and slag removal devices, the oil separation and slag removal device has the advantages that the filter screen arranged on the oil separation and slag removal device is fixed in the filter box in a clamping manner, and a user can conveniently take and place the filter screen, so that the filter screen can be conveniently cleaned or replaced; and therefore, the convenience in maintenance of the filter box is improved, the time for replacing the filter screen when the device is shut down is shortened, and the working efficiency of the device is improved.
