Description

Take boats and ships pressure type draft remote measurement system of pipeline function of blowing through

Technical Field

The utility model relates to a take pipeline to blow through boats and ships pressure type draft remote measurement system of function belongs to the marine system field.

Background

Various ships are provided with a draft remote measuring system for monitoring the draft state of the ships. The type of the draft remote measuring system is divided into an air blowing type and a pressure type. The pressure type draft remote measuring system is characterized in that a pressure sensor is installed on a short pipe at a side opening, the pressure value of seawater in the side pipe is obtained through the pressure sensor to obtain the height of the seawater at the side opening, and the draft of the ship can be obtained after correction according to the height of the side opening.

However, in many types of ships, such as crane ships, due to the large amount of ballast water, ballast tanks are arranged on the side of the ship, so that the ships can be protected in midship while the required ballast tank capacity is provided for the ships.

In this case, it is common practice for the pressure-type draft telemetry system to have the sensors mounted on the wall of the ballast tank near the midship and arranged outside the ballast tank in a location where the sensors communicate with the side by means of a side spool through the ballast tank. Or the pressure sensor is arranged in the ballast tank and is directly arranged on the side short pipe.

The sensor is mounted on the wall of the ballast tank near the midship, so that the sensor can be mounted in a dry cabin, which is convenient for maintenance and is beneficial to prolonging the service life of the sensor. But the side spool runs through the entire ballast tank, and if the ballast tank is larger, the spool length may be longer. This leads to the nozzle stub probably to be blockked up by the silt and the foreign matter of topside inflow, and in case the pipeline blocks up will lead to the measuring value of sensor inaccurate, leads to the unable accurate current draft state of understanding boats and ships of crew, brings the hidden danger for the operation of boats and ships. Meanwhile, once the pipeline is blocked, the whole section of the pipeline can be only disassembled to be cleaned, and the workload is large.

If the draft sensor is directly mounted on the side short pipe in the cabin, the sensor needs to be immersed in the ballast tank and submerged by seawater. Therefore, a protection pipe needs to be arranged for the cable of the sensor, the cable is isolated from direct contact with seawater, and arrangement and installation are difficult. Meanwhile, the sensor body is continuously immersed in seawater, so that the damage of the sensor is easily accelerated. Personnel still need to enter the cabin to maintain and replace after the damage, and the maintenance workload is relatively large.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is when boats and ships are equipped with the topside ballast tank, when pressure type draft remote measurement system's draft sensor was installed in the ballast tank, the difficulty was arranged to the system, and the sensor fragile and maintenance difficulty.

The draft sensor is arranged on a bulkhead of the ballast cabin close to the midship and is arranged in a place outside the ballast cabin, and the sensor is connected with the shipboard open hole through a long short pipe to acquire the outboard seawater pressure. The pipeline is easily blocked by silt and foreign matters, and the normal operation of the system is influenced after the pipeline is blocked. And the workload of dredging the pipeline again after the pipeline is blocked is also larger.

In order to solve the technical problem, the technical scheme of the utility model is to provide a pressure type draft remote measuring system with a pipeline blow-through function, which is characterized by comprising a sensor maintenance ball valve, wherein one side of the sensor maintenance ball valve is provided with a pressure sensor, and the other side of the sensor maintenance ball valve is connected with a three-way short pipe; the other two sides of the three-way short pipe are respectively connected with a compressed air supply stop check valve and a communicating pipe; the compressed air supply stop check valve is connected to the compressed air system through a compressed air supply pipe; the other end of the communicating pipe is connected with the pressure stabilizing cylinder; the pressure stabilizing cylinder is a three-way pipe, and the other two sides of the pressure stabilizing cylinder are respectively connected with a vent pipe and a side valve; the tail end of the vent pipe is provided with a vent pipe shut-off valve.

Preferably, the side valve is mounted on a side seat plate.

Preferably, the sensor maintenance ball valve, the compressed air supply stop check valve, the side valve and the ventilation pipeline stop valve are made of seawater corrosion resistant materials.

Preferably, the pipeline material that the system used is resistant sea water corrosion steel pipe.

Preferably, the pressure sensor is arranged on a cabin wall of the ballast cabin close to a midship, and is arranged in a place outside the cabin, and the environment of the place is dry and stable, so that the service life of the sensor is prolonged.

Preferably, the compressed air system provides compressed air for blowing, and the compressed air is compressed air with the pressure of 0.8MPa

The system has a blowing-through function, can regularly blow through the short pipe connecting the sensor and the side, prevents the pipeline from being blocked, maintains the long-term stable operation of the system, and reduces the workload of maintenance.

The utility model provides a take pipeline to blow through boats and ships pressure type draft remote measurement system of function, it blows through the function step as follows:

step 1: and closing the sensor maintenance ball valve and closing the valve by the vent pipe.

Step 2: and opening a compressed air supply stop check valve to blow through the pipeline.

And step 3: and observing whether bubbles appear on the side, wherein if the bubbles continuously appear on the water surface, the pipeline is blown through.

And 4, step 4: and after the blowing-in is finished, closing the compressed air supply stop check valve, opening the sensor maintenance ball valve, closing the vent pipe stop valve, and recovering the normal operation of the system.

The beneficial effects of the utility model reside in that, compare in conventional pressure type draft sensor installation pattern, remaining with the sensor install under the prerequisite of the advantage in the under-deck, can reduce the risk of system's trouble through simple operation, the cycle that the extension system overhauld.
