Abstract
The invention relates to a ship and boat detecting device, in particular to a sealing detection device of a glass reinforced plastic scientific investigation ship. The sealing detection device of the glass reinforced plastic scientific investigation ship is characterized by being provided with a detection sucking disc, an air outlet nozzle is arranged on the detection sucking disc, one end of a sucking tube is connected with the air outlet nozzle, and the other end of the sucking tube is connected with a negative pressure device. The sucking tube is provided with an air pressure gauge and a stop valve, and a round sealing band is arranged on the detection sucking disc so as to ensure the sealing performance of the detection sucking disc and improve the detection accuracy. When the sealing detection device is used, one end of a barrel-shaped channel traversing a ship body is sealed, the detection sucking disc is buckled at the other end of the barrel-shaped channel, then the stop valve is opened, the negative pressure device sucks out air in the barrel-shaped channel and forms negative pressure, and the air pressure gauge is observed. When the air pressure gauge reaches to a rated value, the stop valve is closed, and change of the air pressure gauge is observed. The pressure of the air pressure gauge does not change shows that the sealing performance of the barrel-shaped channel is good; and the pressure of the air pressure gauge changes shows that the air enters the barrel-shaped channel, the barrel-shaped channel is not sealed tightly, problems occur in the sailing process, and leakage points are required to find and maintain. The sealing detection device of the glass reinforced plastic scientific investigation ship has the advantages of being simple in operation, time-saving, labor-saving, high in detecting accuracy and the like.
Description
Technical field
The present invention relates to the pick-up unit of ships and light boats, specifically a kind of easy to operate, accurate fiberglass scientific surveying ship tightness detection apparatus of detection.
Background technology
We know, all to carry out sealing propertytest after glass fibre reinforced plastic ship makes at present, particularly be equipped with lateral thruster in, large-scale ships and light boats and fiberglass scientific investigation ship, lateral thruster is in order to improve the maneuvering performance of boats and ships, make the ferry glass reinforced plastic boat can be rapidly at water surface transverse moving left and right, can carry out quickly and easily location, displacement etc. on the water surface, so that exploration, investigate.At present the lateral thruster of fiberglass scientific investigation ship is to be provided with the cylindrical channel that traverses hull at hull, is provided with transmission shaft in the cylindrical channel, and the transmission shaft two ends are provided with the thruster screw propeller, and transmission shaft is connected with engine in the hull through side steering.Because during thruster spiral prize work, the hydraulic pressure utmost point in the cylindrical channel increases, be easy to produce drainage, so cylindrical channel is the emphasis of sealing detection, existing pick-up unit is to adopt hydraulic type, whether the pressure by water pressure gauge changes to detect sealing effectiveness, and the deficiency of this method is: the cylindrical channel two-port is difficult for sealing, troublesome poeration, wastes time and energy.When slight seepage appears in the sealing between lateral thruster and the cabin, in the process of trial voyage or flight, be difficult for being found, after coming into operation, be easy to so cause large-area leaking and the accident that meets accident.
Summary of the invention
The objective of the invention is to solve above-mentioned the deficiencies in the prior art, a kind of easy to operate, fiberglass scientific surveying ship tightness detection apparatus that whether accuracy of detection is high, result of use is good can just tightly detect sealing between lateral thruster and the cabin when shipbuilding is provided.
Of the present invention can reaching by following measure.
The present invention can reach by following measure.
A kind of fiberglass scientific surveying ship tightness detection apparatus is characterized in that being provided with the detection sucker, detects sucker and is provided with outlet nozzle, and suction pipe one end is connected with outlet nozzle, and the other end is connected with negtive-pressure implement, and suction pipe is provided with rain glass and stop valve.
Detection sucker of the present invention is provided with the circular seal band, to guarantee to detect the sealing of sucker, improves accuracy of detection.
When invention is used, the cylindrical channel one end sealing of hull will be traversed, detect the close cylindrical channel other end that is buckled in of sucker, then open stop valve, negtive-pressure implement is with the air sucking-off in the cylindrical channel and form negative pressure, observes rain glass, when rain glass reaches ratings, stop valve is closed, observe the variation of rain glass air pressure, if rain glass pressure does not change, the cylindrical channel good seal is described, as press barometric pressure to change, illustrating has gas to enter in the cylindrical channel, poorly sealed, can not go wrong during navigation, keep in repair after searching the leak point, have simple to operate, time saving and energy saving, the accuracy of detection advantages of higher.
Description of drawings
Fig. 1 is a kind of structural representation of invention.
Fig. 2 is that the A of Fig. 1 is to view.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in the figure, a kind of fiberglass scientific surveying ship tightness detection apparatus, be provided with and detect sucker 1, detect sucker 1 and be provided with outlet nozzle 2, suction pipe 3 one ends are connected with outlet nozzle 2, the other end is connected with negtive-pressure implement 4, suction pipe 3 is provided with rain glass 5 and stop valve 6, and described detection sucker 1 is provided with circular seal band 7, to guarantee to detect the sealing of sucker, improve accuracy of detection, during use, with traversing the cylindrical channel one end sealing of hull, detect the close cylindrical channel other end that is buckled in of sucker, then open stop valve, negtive-pressure implement is with the air sucking-off in the cylindrical channel and form negative pressure, observes rain glass, when rain glass reaches ratings, stop valve is closed, observe the variation of rain glass air pressure, if rain glass pressure does not change, the cylindrical channel good seal is described, as press barometric pressure to change, illustrating has gas to enter in the cylindrical channel, poorly sealed, can not go wrong during navigation, keep in repair after searching the leak point, the present invention has simple to operate, time saving and energy saving, the accuracy of detection advantages of higher.
