The invention discloses a manual wheel type steel rail ultrasonic flaw detection car. The manual wheel type steel rail ultrasonic flaw detection car comprises a wheel underframe, a wheel type probe mounted between front and rear guide wheels of the wheel underframe, and an ultrasonic flaw detector mounted on the flaw detection car. A wheel axle between each guide wheel and the wheel underframe is sheathed with a spring; the wheel axles connected at two ends of the wheel type probe are mounted in axle holes formed in a probe fixing block and a probe adjusting block on two sides of the wheel underframe, the probe adjusting block is provided with a rectangular axle hole and a kidney-shaped mounting hole, the rectangular axle hole is adaptive to a flat wheel axle at one end of the wheel probe inserted into the axle hole, the probe adjusting block under the rectangular axle hole is provided with a threaded hole, two sides of the wheel underframe are respectively connected with a lateral plate inclined backwards from bottom to top through a lateral plate fixing block, and a water brush under the wheel underframe is connected with a water tank through a water pipe; and an ultrasonic flaw detector inclining platform is fixed between the two lateral plates above the water tank by screws, and the end parts of the two lateral plates are provided with hand rails of push hands in a penetration manner.

The invention discloses a concrete central protection fence, and relates to the technical field of public facilities. The device comprises a base, stand columns and a guardrail, wherein the base is abase composed of concrete, the stand columns are arranged on the base at intervals; the guardrail comprises an upper cross rod, a lower cross rod and a vertical rod; the two ends of the upper cross rod are fixed at the upper ends of two adjacent stand columns, and the two ends of the lower cross rod are fixed at the lower ends of the two adjacent stand columns, the vertical rod is arranged betweenthe upper cross rod and the lower cross rod, one end of the vertical rod is fixed on the upper cross rod, and the other end of the vertical rod is fixed on the lower transverse rod. The concrete central protection fence has the advantages that the structure is simple, the anti-collision effect is good, the appearance is delicate and attractive.

The invention discloses a concrete protective fence, and relates to the technical field of public facilities. The device comprises a base, stand columns, a transverse rod and a stand rod, wherein thebase is a base composed of concrete, a connecting plate is fixedly arranged on the base, and a mounting hole used for fixing and mounting the stand columns is formed in the connecting plate, the standcolumns are fixedly arranged on the base at intervals, through holes are formed in the upper ends of the stand columns, and the cross bar penetrates through the through holes of the stand columns andis connected between two adjacent stand columns, the stand rod is arranged between the connecting plate and the transverse rod, the upper end of the vertical rod is fixed on the transverse rod, and the lower end of the vertical rod is fixed on the connecting plate. The concrete protective fence has the advantages that the structure is simple, the anti-collision effect is good, the appearance is delicate and attractive.

The invention relates to a novel cover plate for a cable trench. The novel cover plate comprises a cover plate body; the front end of the cover plate body has a convex arc shape, while the rear end has a concave arc shape; a hasp which has a convex arc shape is arranged in the middle of the front end; a rear hasp beam which has a concave arc shape is arranged at the rear end; a rear gap which hasa concave arc shape is formed between the rear hasp beam and the cover plate body; and the hasp is matched with the rear hasp beam, and the length of the rear hasp beam is greater than that of the hasp. A side hasp beam which has a concave arc shape is arranged in the middle of two sides of the cover plate body; a side gap which has a concave arc shape is formed between the side hasp beam and thecover plate body; and the length of the side hasp beam is equal to or greater than that of the hasp. Compared with the prior art, the cover plate has the advantages that: the cable cover plates can be randomly connected with each other horizontally or longitudinally; the cover plates are integrated into a whole after completely paved, so the entire compressive strength of the cover plates is improved and the damage of external force to the cable is reduced; and moreover, the pavement requirements on future increase of cable branches and the turning direction of the cable trench can be met.

The invention discloses a robotic fish with an independent chain-shaped tail support and a snorkeling method of the robotic fish. The robotic fish with the independent chain-shaped support comprises a head, a middle supporting plate, a tail, a pectoral fin and a tail fin. The head comprises a left head shell, a right head shell, a trapezoid partitioning plate, a pectoral fin rudder support, a pectoral fin rudder, a planar double-rocking-bar mechanism, a pectoral fin shaft, a pectoral fin shaft supporting pat, a battery and a circuit board, and the tail comprises the chain-shaped tail support, a fish skin, a first joint, a second joint, a third joint, a first linkage disc, a second linkage disc, a rudder fixing part and a tail fin clamp. The tail fin comprises a tail fin piece and a tail fin insertion part. The pectoral fin comprises a left pectoral fin piece and a right pectoral fin piece. The robotic fish is beautiful, exquisite and vivid in shape and can be kept in a reasonable form when swimming and turning. The independent chain-shaped tail support is compact in structure, convenient to machine and low in cost and allowed to be independently detached and can keep the robotic fish in the form well when swimming underwater.
