The invention discloses a fixing protective cover for a sensor. The fixing protective cover comprises a base plate. Fixing screw holes are formed inside the base plate; one fixed plate is arranged onthe top of the base plate and a limit rod is arranged at one side of the fixed plate; springs are arranged at the bottom of the limit rod, a clamping plate is arranged at one side of the springs, a sealing ring is arranged at one side of the clamping plate, a guard plate is arranged at one side of the sealing ring, and a protective layer is arranged at the bottom of the guard plate. With arrangement of the limit rod, the springs, the guard plate and the clamping plate, compression of the springs is facilitated, the guard plate can be removed so that the sensor can be removed for maintenance conveniently, and use is facilitated; with the fixing screw holes, the protective cover can be fixed conveniently; with the sealing ring, water can be prevented from entering effectively; with the protective layer, the sensor can be protected well.

The invention discloses an elevator integrated roller guide shoe bracket, which comprises a shoe seat, two sets of left and right mounting seats and a rectangular frame. The inner two sides of the shoe seat are provided with vertical clamps for clamping the upper and lower two sets of rectangular cross bars The middle parts of the rear ends of the upper and lower two groups of rectangular cross bars are connected by a fixing plate, and a first roller is movably connected between the two groups of the connecting plates; the rear end of the mounting seat is provided with a rectangular sleeve, and the rectangular sleeve The cylinder is sleeved on the two ends of the corresponding rectangular crossbar, the interior of the rectangular frame is movably installed with two sets of upper and lower second rollers, and the upper and lower two sets of connecting blocks at the rear end of the rectangular frame are fixed to the positioning grooves on the inner side of the mounting seat. The mounting seat is fixed on the inner side of the shoe seat by a first bolt. The rectangular frame, the mounting seat and the fixing plate of the present invention are convenient for initial positioning and installation, and also convenient for subsequent overall removal and maintenance; the rectangular frame and the mounting seat are easily fixed, installed and disassembled, and the overall assembly is firm and stable.

The invention relates to municipal engineering, in particular to a river channel diverting and blocking device for water conservancy engineering and a method for using the same. Adjust according to the water level demand, and then control the water storage capacity. After the dam body is raised, it is supported by the dam body support device, and a gap is formed between the river bed and the lower end of the dam body. The pressure of the water flow increases, which in turn leads to an increase in the speed of the water flow, which can achieve a good dredging effect. The bottom of the dam body and the river bed are not fixed, which is convenient for removal and maintenance. The dam body includes a support tube, and there is a filling core in the support tube. By controlling the weight of the filling core , can control the difference between buoyancy and gravity, and then control the stability of the dam body, set up a corrosion-resistant layer and a waterproof layer, which has a good waterproof and anti-corrosion effect and a long service life.

The invention discloses an energy-saving transformer with a high-stability wall-mounted component, which belongs to the technical field of transformers and includes a transformer body. The upper and lower sides of the transformer body are provided with heat dissipation mechanisms, and the left and right sides of the transformer body are provided with driving mechanisms. , the upper and lower ends of the driving mechanism are respectively fixedly connected to the opposite surfaces of the two heat dissipation mechanisms. In the present invention, by setting the heat dissipation mechanism, when the pressure plate moves close to the transformer body, it can squeeze the air bag, and the air in the air bag can be sprayed out through a plurality of nozzles, and the nozzles blow cold air into the inside of the transformer body. The side airbags can spray air at the same time. At this time, the air blown into the transformer body can form convection, absorb heat and squeeze each other. Finally, the hot air is evenly sprayed out through the multiple heat dissipation holes on the left and right sides of the transformer body to achieve the best cooling effect on the transformer body. The effect of internal heat dissipation.
