Description

Automatic measuring equipment for fishing boat inclination test
Technical Field
The invention relates to a measuring device for an inclination test of a ship, in particular to an automatic measuring device for an inclination test of a fishing boat.
Background
After the fishing boat is newly built and the boat body is significantly reformed, an inclination test is required to be carried out so as to determine the weight and the gravity center of the fishing boat, and the completion stability calculation is carried out on the basis of the weight and the gravity center. It is conventional practice to estimate the weight of 4 or 6 sets of moving weights and carry them by a carrier. And two groups of pendulums are arranged at proper positions on the ship, the pendulums are placed in the water tank, and technicians manually read the swing amplitude.
Because fishing boats are smaller in size than commercial boats, the weight of the moving weight required for the inclination test is lighter, and the excessive weight on the boat can have adverse effects on the test result. Each group of the moving weights of the inland river fishing vessel with smaller scale is even less than 80kg, and a carrier is required to descend when the swing amplitude of the pendulum bob is read for reducing test errors. But the traditional method at least needs two persons to read the swing amplitude data of the pendulum on the ship. The weight of a group of moving weights was already approached, calculated as an average of 75kg per person weight, and the person's center of gravity could not be accurately determined, meaning that the accuracy of the test was inaccurate. The final inclination test result will cause a certain error and affect the stability calculation of the whole fishing boat, and a certain margin is usually added in the calculation.
According to the specification requirement, even if the mode of adopting the U-shaped pipe reads the roll value of the fishing boat, a group of pendulum bob is still needed for measurement. According to the requirement, the cycloid length of the pendulum bob needs to reach 3 meters, and the support is usually assembled by using local materials on site, so that time and labor are wasted, and the standard is difficult to reach.

Detailed Description
The following describes embodiments of the present invention in detail, and the embodiments are developed based on the technical solutions of the present invention, and provide detailed implementation manners and specific operation procedures.
According to the inclination test regulation, a movable heavy object is arranged at a proper position on the fishing boat, water tanks 4 are arranged at the positions of the bow and the stern, the water tanks 4 are formed by welding stainless steel, and two groups are arranged. The proportional telescopic rod 1 is opened and fixed with the bracket mounting slot through the bolt base, and the pendulum bob 6 is positioned. The pendulum weight 6 is submerged by adding water into the water tank. According to the inclination test rule of the fishing boat, the weight is moved for 8 times, and the initial state is added, so that the invention is adopted to measure 9 groups of states.
① start collection, test state is ready, collection is started by clicking a button in a corresponding PC terminal or a mobile phone terminal APP, the device automatically collects the left and right swing amplitude data of the pendulum bob and synchronously sends the data to the terminal, the number of groups for recording swing amplitude can be set at the terminal, the left maximum value and the right maximum value of the same swing frequency are one group, and the default is 20 groups.
② data are read and sent, when the pendulum bob 6 swings, the gravity acceleration sensor in the pendulum bob 6 tests the gravity acceleration of the pendulum bob when the pendulum bob swings vertically and in the left-right maximum amplitude, the displacement sensor tests the amplitude of the pendulum bob, and the WIFI module transmits the test data to the PC terminal or the mobile phone terminal APP.
③ moving the heavy objects, which need not be too heavy for the fishing boat to discharge water and have small main dimension, can be moved by manual or crane, and can be moved from one side to another side at a time.
④, the measurement is continued, each time the moving weight is carried out, the personnel returns to the initial position, the tester continues to click the start button in the PC terminal or the mobile phone terminal APP to start to collect a new set of swing amplitude data.
