However, due to the needs of modern logistics, there are requirements for ships to sail across the three water systems of river, river and sea. The height of the mast is required not only to meet the observation at sea, but also to meet the restrictions on the height of the mast by the bridges and other facilities on the river when the ship enters the river. Similarly, the height of the water level also changes at any time, so the existing fixed-height masts are difficult to meet the requirements of ships sailing across the three water systems of rivers, rivers and seas.

Embodiment Construction
[0035] The present invention will be further described below in conjunction with the accompanying drawings.
[0036] Such as figure 1 , 2 , The marine telescopic mast shown in 3 and 4 is composed of two identical and oppositely arranged telescopic joint groups 1, two power bodies 2, a bridging body 3, and a vertical pole 4:
[0037] Each telescopic joint group 1 has at least 3 mast joints that are sequentially guided and slidably combined in the length direction, and a traction piece is connected between the front mast joint and the rear mast joint adjacent to a certain middle mast joint. The traction member bypasses the rotating member arranged at the top of the middle mast section and one end thereof is connected to the lower part of the rear mast section;
[0038] Such as Figure 8 , 9 As shown, it is a telescopic section group composed of 3 mast sections, the first mast section 11 (i.e. at the front mast section) and the third section mast section 13 (i.e. at the rear ...

The invention relates to a ship used retractable mast, and belongs to the ship construction. The prior mast with fixed height is unlikely to meet the requirements for ships navigating across three water systems of rivers, streams and seas. The retractable mast includes two identical retractable segment groups arranged in the same direction, two drivers respectively collocated to the two retractable segment groups and respectively positioned inside the two retractable segments in such a state that the two drivers can move on the drive-corresponding second mast segment in the vertical direction;a bridge connection body bonded with the tail mast segments is arranged between the two tail mast segments of the two retractable segment groups; and a vertical pole is connected with the bridge connection body. The two retractable segments can retract at the same time under the action of the drivers to lift the bridge connection body and the vertical pole, thus achieving retraction of the entiremast and adjusting the height of the mast to meet the requirement for ships navigating across three water systems of rivers, streams and seas.
Description
technical field [0001] The invention belongs to ship structure, in particular to a ship telescopic mast. Background technique [0002] The height of the existing marine mast is basically fixed. However, due to the needs of modern logistics, there are requirements for ships to sail across the three water systems of river, river and sea. The height of the mast is required not only to meet the observation at sea, but also to meet the restrictions on the height of the mast by the bridges and other facilities on the river when the ship enters the river. The same, the height of water level also changes at any time, so the mast of existing fixed height is difficult to satisfy the requirement that ship crosses three kinds of water systems of river, river and sea. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to overcome the defect that existing fixed-height masts cannot meet the requirements of ...
