TH47902A - Water-cooled power meter; no splashing or spraying. - Google Patents

Abstract

DC60 (09/05/44) The splash-proof mechanical power meter (Prony brake) described in this invention has a splash guard to prevent splashing onto nearby equipment, such as electrical systems. This splash guard is attached to the wheel axle but does not rotate with it. It is supported by a bearing, which is protected from water by a seal attached to the same axle. Furthermore, a cooling water flow system lubricates and cools the seal before transferring heat from the wheel and dissipating it. This results in a cost-effective splash-proof power meter compared to other types. This results in a waterproof, splash-proof power meter at an affordable price compared to other types.

Claims (1)

1. The water-cooled power meter consists of a wheel (5) which is a tube-shaped cylinder with one end closed. The other end of the wheel (5) has a ridge (26) that extends inward parallel to the other side of the wheel to prevent water from being trapped inside the wheel (5). The wheel (5) is attached to the rotating shaft (15) by a key (24), and on the side of the wheel (5) are caliper brakes (1,2) with a brake pad (11) attached to the caliper brake (1,2) making contact with the upper surface of the wheel (5) to create friction. The caliper brake (1,2) has a shaft (3) attached to the caliper brake support beam (4). The other end of the caliper brake has a vertical shaft (8) and a spring (16) to push the caliper so that the brake pad does not make contact with the surface of the wheel (5), and there is a screw (6) for adjusting the caliper to make contact with the wheel (5) when the caliper brake is needed. And there is a splash guard (20) mounted on a bearing mounted on the rotating shaft (15), which prevents it from rotating with the shaft (15), and on the top of the splash guard there is a water inlet (13) which is bent to allow water to flow through the shaft and seal (17) to the bottom of the wheel (5), where the water at the bottom of the wheel is scooped out of the wheel as the wheel rotates by an outlet (12) which has an inner end bent downwards in the opposite direction to the rotation of the wheel, and this outlet mounted on the splash guard. Specifically, the splash guard (20) is a circular plate covering the inner wall of the opening of the wheel (5), mounted on a bearing mounted on the rotating shaft (15), which prevents it from rotating with the shaft (15), where the edge of the splash guard (20) does not come into contact with the ridge of the edge (26), and on the inside between the rotating shaft and the splash guard there is a seal (17) to prevent water from reaching the bearing.
