Benefits of technology

0015] It is another objective of this invention to provide a non-contact signal relay for use in a reel structure to facilitate transmitting electric signals from an electric information source attached to the reel structure to a monitoring station without a rotational intervention.
0016] In accordance with an aspect of the present invention, a water-monitoring apparatus includes a frame installed on a well or a bank by water. A reel is mounted on the frame. A constant torque device is used to exert a constant torque on the reel. A cable including a lower end and an upper end is wound on the reel. A buoy is connected with the cable. A detecting device includes at least one sensor. The detecting device is carried via the buoy and electrically connected with the lower end of the cable. The detecting device is used for detecting at least one water quality parameter. A signal relay is electrically connected with the upper end of the cable for receiving an electric signal from the detecting device.

Problems solved by technology

While developing, the world is encountering a more and more serious problem of pollution.
Such pollutants may be released into water directly, or may be washed into the water by rain.
Once introduced into the water, such pollutants inevitably increase costs in treating the water and very often harm human bodies, life stock and aquatic lives.
Some water analyses are performed manually, however they are cumbersome.
It, however, is found difficult to have the pipes catch up with the water level changing vigorously from season to season.
When the water level becomes too low for the pipes ...

second embodiment

[0038] Referring to FIG. 4, the present invention is shown.

[0039] The embodiment of FIG. 4 is identical to that of FIGS. 1 to 3 except for including a level-determining device for determining the water level. The level-determining device includes a pulley 40 mounted on the frame 19. A length of the cable 15 is wound on the pulley 40 so that the cable 15 rotates the pulley 40 as the buoy 30 rises or falls together with the water level. A number of magnets 41 are evenly arranged near or on the periphery of the pulley 40. A magnetic detector 45 is mounted on the frame 19 for detecting each magnet 41 passing by. When the water level changes, the buoy 30 moves up or down, thus causing the pulley 40 to rotate counter-clockwise or clockwise and the magnets 41 to move. The magnetic detector 45 detects how many magnets 41 pass by and in what direction in order to determine how much the water level rises or falls. The cable 15 is further wound on a pulley 42 mounted on the frame 19. Thus, the...

third embodiment

[0040] Referring to FIG. 5, the present invention is shown. A constant torque spring assembly 50 is used in the embodiment of FIG. 5 in order to substitute for the coil spring 13 of the embodiment of FIGS. 1 to 3. The constant torque spring assembly 50 includes an axle 51 mounted on the frame 19 by means of a bearing 52. The axle 51 is connected with the reel 10 so that they are allowed to rotate together. Furthermore, the axle 51 is connected with one of two drums 53 of the constant torque spring assembly 50. Thus, the constant torque spring assembly 50 exerts a constant torque on the reel 10 through the axle 51. The constant torque spring assembly 50 is known in the art and will not be described in further detail.

Abstract

A water-monitoring apparatus includes a frame installed by water. A reel is mounted on the frame. A cable including lower and upper ends is wound on the reel. A buoy is connected with the cable. At least one sensor is used to detect a water quality parameter and to produce a signal representative of the water quality parameter. The at least one sensor is carried via the buoy and electrically connected with the lower end of the cable. The reel can be rotated to adjust a length of the cable extending from the reel so that the at least one sensor can always be immersed in the water. A signal relay includes a first block electrically connected with the at least one sensor and a second block electrically connected with a monitoring station wherein the first and second blocks are connected with each other in a non-contact electric manner.

Description

BACKGROUND OF INVENTION[0001] 1. Field of Invention[0002] The present invention is directed to monitor water quality and, more particularly, to a water-monitoring apparatus for detecting water quality parameters at constant depths.[0003] 2. Related Prior Art[0004] While developing, the world is encountering a more and more serious problem of pollution. Water pollution could be the worst among all kinds of pollution. More and more pollutants are dumped to reservoirs and open channels from fixed sources, e.g., factories and farms, or from mobile sources, e.g., vehicles. Such pollutants may be released into water directly, or may be washed into the water by rain. Once introduced into the water, such pollutants inevitably increase costs in treating the water and very often harm human bodies, life stock and aquatic lives.[0005] Before any proper measure can be taken to solve the problem of water pollution, by what pollutants and to what extent the water is polluted must be figured out. I...
