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 water quality at a predetermined depth at a fixed point, in particular, a measuring device is mounted, a part 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 measurement device that generates and moored (tension leg type).

[0002]

2. Description of the Related Art In recent years, the number of cases of periodically measuring water quality and the like for pollution control is increasing. However, the conventional measuring method is to cross a pier from a shore to an offshore or to measure at a measuring point by a ship. Or the like, where water is collected at predetermined water depths and analyzed. An observation room for installing equipment is also installed, but it can be installed at the observation point using a fixed method supported by supports in shallow places, but when the pier is extended to the offshore, the navigation of the ship This fixing method cannot be adopted because it is in the way. Further, when the water depth is several tens of meters or more, it is difficult to plant the columns on the bottom of the water, and when the bottom is composed of sludge sediment, it is very difficult.

[0003]

There is a method of mooring a buoy equipped with various measuring instruments in a swingable state for weather observation and tidal current observation. In this method, the buoy is floated on the water surface. However, it is unsuitable for collecting a variety of data by obtaining a sample from a deep place, and can obtain data only at a very limited depth. In addition, because this floating buoy swings greatly on the water surface,
Sampling and analysis are difficult with the performance of ordinary measuring instruments. Furthermore, it is inappropriate to mount a large number of measuring instruments on the oscillating floating body, and it is impossible to mount a large number of measuring instruments and generators on the actually oscillating floating body.

On the other hand, a large buoy can be provided with a generator as a power source. However, as described above, the generator is easily affected by swinging. And the like, which causes problems such as inaccurate measurement values and damage to equipment. The present invention has been made in view of the above-described problems, and has an object to provide a mooring type measurement device capable of measuring water quality at a predetermined depth in a deep place far away from a shore without affecting a navigating ship. . Furthermore, the installed measuring equipment and communication equipment are hardly affected by the outside temperature, and even if equipment with heat generation such as a generator is installed, the influence of temperature, humidity, vibration, etc. of the measuring equipment and transmitter etc. An object of the present invention is to provide a mooring type measuring device capable of protecting easily susceptible equipment from temperature, humidity, vibration and the like.

[0005]

In order to achieve the above object, a mooring type measuring device according to the present invention has a part against buoyancy.
With a floating body to be used while retracted into the water
A floating device body, a ballast tank installed at the bottom, a measuring equipment room accommodating measuring equipment arranged below the water line, and a generator arranged at a high place above the water line. together with a generator chamber housing to the universal joint and scan the mooring fixed to the installation and the sinker in water bottom
It is moored by weavers .

According to the present invention, there is provided a measuring device in which a part of the body of the floating body is pulled into the water by a mooring line, that is, the device is susceptible to temperature, humidity, vibration and the like in a portion below the water line. It is characterized in that it is arranged, the generator is arranged in a portion on the water line where air intake and exhaust and heat radiation are easy, and furthermore, an entrance is opened at a position near the water line, and this 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 place and can continuously measure the water quality at a predetermined depth. Further, since the measuring instruments are housed in the measuring instrument room below the water line, they are hardly affected by heat and vibration of the generator housed in the generator room at a high place above the water line. Since the measurement equipment room is installed below the water line where the temperature is relatively stable than above the water line, the power consumption of the air conditioning equipment for adjusting the temperature and humidity in the measurement equipment room can be reduced. Since it is housed in the generator room on the line, intake and exhaust and heat dissipation are easy.

Further, since the entrance is provided in the passenger compartment near the water line, unlike a buoy which has an entrance at a normal high place,
It is very easy for people to enter and exit, and it is easy to carry in / out cargo, maintain / check, etc. In addition, this entrance is a watertight door, so it is excellent in watertightness, even in bad weather. It is possible to prevent water from entering the boarding room.

And a part of the floating body 1a is drawn into the water.

In this embodiment, the number of the mooring lines 46 is one. However, when the direction of the floating body 1a needs to be fixed, or when the mooring line 46 has a large tension and there is a problem in strength with a single mooring line 46. Can be moored with a plurality of mooring lines 46. Further, a universal joint 45 is provided between the floating body 1a having the largest swing and the mooring line 46 in order to release the stress generated in the mooring line 46 and the joint due to the swinging of the floating body 1a.

It is transmitted from the telemeter antenna 8a of the top deck 7 using 8b. In addition, a generator 13 is provided in the uppermost generator room 2 in order to prevent an error in the measurement result of the water quality measuring device 27 in the lower measurement equipment room 5 so as to prevent heat, vibration and the like which may cause a measurement error. In addition to reducing the influence, the air conditioner indoor unit 9b installed in the lower measurement equipment room 5 and the air conditioner outdoor unit 9a installed in the top deck 7
And the temperature and humidity of the lower measuring instrument room 4 are kept constant. Since the lower measuring equipment room 5 is provided below the water surface where the temperature change is smaller than the water surface, the power consumption of the air conditioner can be reduced. In order to prevent the load applied to the generator 13 from changing due to the operation state of the air conditioner, and to prevent the voltage generated by the generator 13 from fluctuating, a dummy resistor 23 for load control is provided in the upper measuring instrument room 4. I have.

In addition, this watertight door can be made a double door as shown in this embodiment in order to maintain more complete watertightness. According to this method, the outer door is opened during a storm and the hatch portion is opened. Even if water enters, if the outer door is closed before the inner door is opened, the water does not enter the passenger compartment 3.

Furthermore, the protrusion 40 provided below the lower sensor 30b is inserted through the lattice of the buckling prevention support 37 in the form of a lattice supported by the anchor cable 36a tensioned by the weight 32b, so that the whirling can be prevented. Therefore, the support cable 31b and the signal cable 41 of the lower layer sensor 30b do not become entangled with the guide cable 39.
