A water brake is a type of fluid coupling used to absorb mechanical energy and usually consists of a turbine or propeller mounted in an enclosure filled with water. As the turbine or propeller turns, mechanical energy is transferred to the water due to turbulence and friction. The shock caused by the acceleration of the water as it passes from pockets in the stator to the pockets in the spinning rotor requires energy. That energy heats the water due to the friction as the water moves through the water brake. Almost all of the horsepower of the system turning the rotor (usually an internal combustion engine) is converted into a temperature change of the water. A very small amount of energy is taken by the bearings and seals within the unit. Therefore, water must constantly move through the device at a rate proportional to the horse power that is being absorbed. Water temperature exiting the unit must be kept under 120-160F (50-70 °C) to prevent scale formation and cavitation. The water enters in the center of the device and after passing through the pockets in the stator and rotor exits the outside of the housing though a controlled orifice. The amount of loading is dependent on the level of water inside the housing. Some water brakes vary the load by controlling the inlet water volume only and have a set outlet orifice size depending on the desired hp to be absorbed and some control both input and output orifices at the same time which allows greater control over outlet water temperatures. The housing is vented to the outside to allow air to displace the water as the water level in the unit rises and falls.

Gate with crushing function
The utility model discloses a gate with a crushing function, which relates to the technical field of water gates and comprises a gate frame and a gate body slidably mounted on the gate frame, and a crushing device is fixedly mounted on one side of the upstream of the gate body on the gate frame. The crushing device comprises a crushing rack mounted on the gate frame and two crushing rollers rotationally mounted on the crushing rack side by side, the two crushing rollers rotate in opposite directions and rotate relatively, and a rotation driving device for driving the two crushing rollers to rotate is fixed to the top of the crushing rack; a filter screen is fixedly installed in the area between the smashing roller and the smashing frame and prevents solid waste from entering the space between the smashing roller and the smashing frame. The crushing device is arranged on the upstream of the gate, so that the upstream solid waste is crushed, and the gate is prevented from being blocked by the solid waste or adverse effects on power generation equipment are avoided.

Nondestructive testing probe for thickness of anticorrosive coating of water gate
The utility model relates to the technical field of water gate detection, in particular to a nondestructive detection probe for the thickness of an anticorrosive coating of a water gate. The detection mechanism comprises a mounting plate detachably mounted in the middle of the top face of the gate body, a lifting plate located below the mounting plate and located on the left side of the gate body, and an electric cylinder with a cylinder body mounted on the top face, close to the left end, of the mounting plate. A piston rod of the electric cylinder penetrates through the top face of the mounting plate and extends to the position above the transverse plate end of the lifting plate. According to the utility model, the thickness of the anticorrosive coating of the gate body can be detected through the detection mechanism, the transverse position of the ultrasonic probe body can be adjusted through the design of the detection mechanism, and meanwhile, the height position of the ultrasonic probe body can be adjusted according to detection requirements; therefore, the anti-corrosion layers at different positions on the outer wall of the brake body can be conveniently detected, the position of the ultrasonic probe body does not need to be manually adjusted to carry out detection work, and time and labor are saved.
