Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ship capacity measurement, in particular to a device for measuring the ship cabin capacity. Background Art
[0002] The ship's capacity is a general term for the ship's cabin volume and deck area, which includes the space inside the ship that can be used to load cargo, oil, water, mechanical equipment, and arrange various working cabins and living cabins. The ship's volume is usually divided into concepts such as gross volume, net volume and deadweight. The gross volume refers to the size of the total space inside the ship, including cargo holds, cabins, engine rooms, decks, etc. The net volume refers to the size of the space inside the ship that can be used for cargo storage, minus the space occupied by obstacles and equipment inside the ship.
[0003] Traditional measurement methods include geometric measurement, capacity comparison, mixed measurement, and automatic measuring devices.
[0004] Geometric measurement method: For a regularly shaped cabin, its capacity can be directly calculated by measuring its geometric dimensions such as length, width and height. The geometric dimensions of the cabin can be accurately measured using tools such as laser rangefinders; Capacity comparison method: The capacity comparison method mainly relies on standard metal measuring instruments to measure the capacity of the cabin by injecting water or other media into the cabin. This method has high measurement accuracy, but the operation is time-consuming and consumes a lot of manpower, especially for large-capacity cabins; Mixed measurement method: The mixed measurement method combines the geometric measurement method and the capacity comparison method. It is suitable for measuring the capacity of large irregular ship cabins. For the irregular part of the bottom of the cabin, the capacity comparison method is used for measurement; and the regular part above the cabin is measured by the geometric measurement method; Automatic measuring device: Modern ships also use automated measuring devices, such as ultrasonic flow meters, liquid level sensors, etc., to achieve automatic measurement of cabin capacity.
[0005] However, traditional measurement methods, such as those based on geometric measurement, have the problems of low measurement accuracy and low efficiency. For large ship cabins, whether regular or irregular, the ship cabin capacity is generally calculated by the liquid level difference between the hull and the horizontal plane, but it is inconvenient to read the hull liquid level value. These methods also have the problems of complex operation and low efficiency. Utility Model Content
[0006] Based on this, the purpose of the utility model is to provide a measuring device for the ship's cabin capacity to solve the problems of low measurement accuracy and low efficiency in traditional measurement methods, such as methods based on geometric measurement. For large ship cabins, whether regular or irregular, the ship's cabin capacity is generally calculated by the liquid level difference between the hull and the horizontal plane, but it is inconvenient to read the hull liquid level value. These methods also have technical problems of complex operation and low efficiency.

The measurement value, secondly, through the cooperation between the slider, the slide bar, the float and the scale, it can be determined whether there is an imbalance in the cargo loading in the hull, so that it can be adjusted in time according to the actual situation. This structure can solve the problems of low measurement accuracy and low efficiency in traditional measurement methods. For large ship cabins, whether regular or irregular, the ship's cabin capacity is generally calculated by the liquid level difference between the hull and the horizontal plane, but it is inconvenient to read the hull liquid level value. These methods also have the technical problems of complex operation and low efficiency, which improves the practicability of the entire ship cabin capacity measuring device.
[0009] The utility model is further configured that a second protrusion is symmetrically arranged on the inner side of the fixing block, and first sliding grooves cooperating with the second protrusion are provided on both sides of the scale.
[0010] By adopting the above technical solution, the second protrusion cooperates with the first sliding groove, so that the scale can slide smoothly in the fixed block.
[0011] The utility model is further configured that a clamping block and a limiting block are arranged on both sides of the guide rail, the clamping block is located on the outside of the hull, and the limiting block is located on the inside of the hull.
[0012] By adopting the above technical solution, the mutual cooperation between the provided clamping block and the limiting block can enable the guide rail to be stably connected and fixed to the hull.
[0013] The utility model is further configured that a first protrusion is arranged on the top of the guide rail, and a second sliding groove used to cooperate with the first protrusion is opened on the inner side of the sliding block.
[0014] By adopting the above technical solution, the cooperation between the first protrusion and the second slide groove can enable the slider to slide on the hull more smoothly.
[0015] The utility model is further configured that the bottom of the sliding rod is fixedly connected to a limiting ring, and the length of the sliding rod and the scale is consistent with the height of the hull.
[0016] By adopting the above technical solution, the set limit ring can limit the floating block, preventing the floating block from detaching from the sliding rod during use and affecting the staff's reading of the hull liquid level value. Secondly, when the length of the scale and the sliding rod is consistent with the hull height, the error can be reduced and the measurement accuracy can be improved.
[0017] The utility model is further configured that the measuring instrument is located inside the sliding block, the infrared device is located below the measuring instrument, and the measuring instrument is a laser measuring instrument.
[0018] By adopting the above technical solution, when the measuring instrument is a laser measuring instrument, the dimensions inside the hull can be measured in conjunction with an infrared device.
[0019] The utility model is further configured that a slot for matching with the scale is provided on the inner side of the fixing block, and the scale is in a vertical state with the top of the sliding block.
[0020] By adopting the above technical solution, the slots are arranged to facilitate quick reading of values, and when the scale and the slider are in a vertical state, it can assist professionals to quickly and accurately read the values on the scale.

Through the cooperation between the buoyancy and the float block, the float block will float upward, thereby driving the scale to move upward at the same time, and then read the scale. The value on the scale at this time is the hull liquid level value. At the same time, through the cooperation between the measuring instrument and the infrared device, the size of the hull is measured, and the calculation is combined with the value on the scale to obtain the ship's cabin capacity value. Secondly, through the cooperation between the slider, the slide bar, the float and the scale, it can be judged whether there is an imbalance in the cargo loading in the hull, so as to adjust it in time according to the actual situation. This structure can solve the problems of low measurement accuracy and low efficiency of traditional measurement methods. For large ship cabins, whether regular or irregular, the ship cabin capacity is generally calculated by the liquid level difference between the hull and the horizontal plane, but it is inconvenient to read the hull liquid level value.
