The utility model relates to the technical field of water pump installation, and discloses a water pump installation structure and a water pump thereof. A support plate; the adjusting assembly comprises a vertical shaft, a limiting ring, thrust protrusions and limiting grooves, the vertical shaft is fixedly connected with the supporting plate and rotationally connected with the bottom plate, the limiting grooves are formed in the top of the bottom plate, the thrust protrusions are fixedly arranged at the bottom of the limiting ring and can be clamped into the limiting grooves to lock the position of the vertical shaft, and the limiting ring is elastically connected with the vertical shaft. The limiting ring is pushed upwards, the limiting ring slides along the vertical shaft, the protruding block on the inner ring of the vertical shaft slides along the vertical groove, then the thrust protrusion is separated from the limiting groove, the position of the supporting plate can be adjusted by rotating the supporting plate, the position of the water pump water opening fixedly formed in the top of the supporting plate can be adjusted, then butt joint of the water pump water opening and a pipeline is facilitated, adjustability is high, and practicability is high. And the installation adaptation degree is higher.

The invention discloses an existing building outer wall in-situ reinforcing and repairing method, belongs to the technical field of existing building outer wall repairing, and aims to overcome the defect that an existing existing building outer wall in-situ repairing method is poor in anchoring effect. According to the fixing pin with the knocking expansion and grouting functions, connection between the fixing pin and a wall is tighter and firmer through outward expansion of the bent portion of the expansion pipe and grouting operation, the tensile bearing capacity standard value of the fixing pin with the knocking expansion and grouting functions is effectively increased through the reinforcing fixing structure at the inner end, and the problem that the tensile bearing capacity standard value is low in the prior art is solved.

The utility model discloses a kind of driving device for pipeline detection, it is related to pipeline detection technical field, including connecting disc, the surface of connecting disc is provided with power mechanism, the power mechanism includes the fixed cover fixedly connected with connecting disc, the middle part of the fixed cover is rotatably connected with transmission gear, the middle part of transmission gear is connected with support mechanism, this driving device for pipeline detection, by bolt, connecting disc is fixedly installed in pipeline detection tail part, by pressure pipe, support rod is provided with pulling force, make power wheel and pipeline inner wall closely resist and touch, rotate by first sprocket control power wheel, power wheel and pipeline inner wall friction generates thrust, drive pipeline detection device to move forward, when meeting elbow, by transmission gear control support plate rotation, make support rod drive fixed shell rotation, adjust the position of power wheel and pipeline resist and touch, make power wheel and elbow outermost circle inner wall resist and touch, improve the stability of driving detection device movement.

The utility model belongs to the technical field of blackboard cleaning, and particularly relates to an automatic blackboard cleaning device which comprises a blackboard body, a tray fixedly installed at the bottom of the blackboard body, a fixing sleeve fixedly installed on one side of the blackboard body, a motor fixedly installed at the bottom of the fixing sleeve, a threaded rod arranged at one end of the motor and a sliding block arranged on the threaded rod. A mounting plate is fixedly connected to one side of each sliding block, a cleaning mechanism is arranged at the top of the blackboard body, the motors are electrically connected with an external power source through wires, the motors are fixedly mounted at the bottoms of the fixing sleeves through bolts, threaded through holes are formed in the sliding blocks, and the sliding blocks are in threaded sliding connection with the threaded rods through the threaded through holes. The movable groove and the compression spring are arranged in the mounting plate, the cleaning brush plate is movably sleeved with the movable groove, the cleaning brush plate can tightly abut against the surface of the blackboard body by pushing the cleaning brush plate through the compression spring, the cleaning effect can be improved, and better work and use are facilitated.

The utility model relates to the technical field of hose joints, in particular to a non-leakage hose joint for connecting different pipe diameters, which comprises a first butt joint, the first butt joint is connected with a second butt joint through a fixing structure, the first butt joint is rotatably connected with a rotating ring, the rotating ring is fixedly connected with four buckles, and the first butt joint is connected with the second butt joint. Four protruding blocks are fixedly connected to the second butt joint, the buckles abut against the protruding blocks, the first butt joint abuts against the second butt joint, the two ends of each protruding block are of an inclined face structure, a groove is formed in the first butt joint, a second sealing ring is installed on the second butt joint, and the second sealing ring is clamped with the groove. A first hose is mounted on the first butt joint through one mounting structure, a second hose is mounted on the second butt joint through the other mounting structure, and the pipe diameter of the first hose is larger than that of the second hose; the water pipe can be prevented from being twisted and deformed due to the fact that the connectors drive the water pipe to rotate, so that smoothness of water flow is guaranteed, and stability of connection of the two connectors is enhanced.

The invention discloses a detachable telescopic rod specially used for fire detection. The structure of the telescopic rod comprises a cylinder, a telescopic rod and a disassembly detection mechanism. The lower end of the telescopic rod is installed inside the cylinder by a clearance fit, and the top of the telescopic rod is provided with a disassembly detection mechanism. The opening and closing piece is squeezed by an electric wire, and the electric wire enters the inside of a shrinking plate individually, and then the outer side of the electric wire contacts the contact piece. At this time, a sliding shaft at the inner end of the fixed rod slides on the right end of the contact piece, so that the size of the openings at the left ends of the upper and lower contact pieces is adjusted to ensure that the outer side of the electric wire is tightly contacted, so that effective time-length contact detection is performed on the individual electric wires. The plate body is driven by the telescopic hose to perform elastic squeezing, so that the plate body and the elastic pull rope support the other electric wires except the electric wire to be tested, so as to avoid a plurality of electric wires being gathered together and improve the accuracy of the detection data.
