Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for continuously measuring the water quality at a predetermined water depth at a fixed point, in particular, a measuring device is mounted and a part of the main body of a floating body is pulled into the water by a mooring line and tension is applied to the mooring line. The present invention relates to a buoy type measuring device that generates mooring and is moored (tension leg type).

[0002]

2. Description of the Related Art Recently, there are an increasing number of cases where water quality is regularly measured for pollution control, etc., but the conventional measurement method is to cross the jetty from the shore to the offshore, or to measure the point by ship. There is a method adopted such as going to the area, collecting water at a predetermined depth and analyzing it. In addition, although an observation room is also installed to install equipment, if the water depth is shallow, it can be installed at the observation point by a fixed system supported by stanchions. It is not possible to adopt this fixing method because it interferes with. Furthermore, if the water depth is several tens of meters or more, it is difficult to plant the pillars on the bottom of the water, and it is very difficult if the bottom of the water is composed of sludge deposits.

[0003]

There is a method of mooring a buoy equipped with various measuring devices in a swingable state for meteorological observation and tidal current observation. In this method, the buoy is floated on the water surface. However, it is unsuitable for collecting various data by obtaining samples from deep water, and only data at a very limited water depth can be obtained. In addition, this floating buoy swings greatly on the water surface,
Sampling and analysis are difficult with the performance of ordinary measuring instruments. Furthermore, it is not suitable to mount many measuring devices on the swinging floating body, and it is impossible to mount many measuring devices or generators on the swinging floating body.

On the other hand, in a large buoy, it is possible to install a generator as a power source. However, similarly to the above, the generator is easily affected by rocking, and when the generator is installed, the heat and vibrations of the generator may cause measurement equipment and transmitters. However, there is a problem that the measured value becomes inaccurate and the device is damaged. In view of the above problems, the present invention is to provide a mooring type measuring device capable of measuring the water quality and the like at a predetermined water depth in a deep water place far away from the shore without affecting the traveling vessel. .. Furthermore, the installed measuring devices and communication devices are not easily affected by the outside temperature, and even if devices such as generators that generate heat are installed, the effects of temperature, humidity, vibration, etc. on the measuring devices and transmitters, etc. An object of the present invention is to provide a mooring type measuring device capable of protecting easily-received devices from temperature, humidity, vibration and the like.

[0005]

Means for Solving the Problems A mooring type measuring apparatus according to the present invention for achieving the above object comprises a vertically long and cylindrical floating body, a ballast tank installed at the bottom of the floating body, and a water tank. The measuring equipment room containing the measuring equipment arranged below the line, the generator room containing the generator placed at a high place above the water line, and below the generator room and above the water line A measuring device consisting of a passenger compartment, a watertight door is provided at the entrance opened to the passenger compartment, the floating body is a mooring line fixed to a sinker installed on the bottom of the water,
The buoyancy of the floating body is utilized to moor the mooring line in a tensioned state.

The present invention provides a measuring device in which a part of the main body of the floating body is pulled into the water by a mooring line, that is, tensioned mooring, and a portion below the water line is easily affected by temperature, humidity, vibration and the like. It is characterized in that the generator is arranged on the water line where it is easy to take in and exhaust air and radiate heat, and the entrance is opened at a position closer to the water line and the entrance is closed by a watertight door.

[0007]

[Operation] Since the present invention has the above-mentioned structure, it can be installed in a deep water place and can continuously measure the water quality at a predetermined water depth. Further, since the measuring equipment is stored in the measuring equipment room below the water line, it is unlikely to be affected by heat and vibration of the generator stored in the generator room at a high place above the water line. Since the measuring equipment room is installed below the water line where the temperature is relatively stable rather than above the water line, it is possible to reduce the power consumption of the air conditioning equipment for temperature and humidity adjustment in the measuring equipment room, while the generator is Since it is housed in the generator room on the line, it is easy to inhale and exhaust and radiate heat.

Further, since the entrance / exit is provided in the passenger compartment near the water line, unlike a buoy in which the entrance / exit is usually provided at a high place,
It is very easy for people to come in and out, and it is easy to carry in and carry out luggage, maintain and inspect, etc. Moreover, since this entrance is a watertight door, it is excellent in watertightness, even in bad weather. It is possible to prevent the passenger room from being flooded.
