Description

Technical Field

[0001] The utility model relates to a safety warning device for water use. Background Art

[0002] In water transportation, in order to prevent ships from entering dangerous areas, such as shallow areas and reef areas, corresponding safety warning devices, such as navigation marks, need to be set up on the water surface.

[0003] Existing safety warning devices include a hollow floating platform with an anchor sunk to the bottom of the water underneath. The floating platform is connected to the anchor by a rope. By setting the floating platform in a conspicuous color, the floating platform is easy to observe, thereby preventing ships from entering dangerous areas. As a further optimization, a lighting system can also be set on the floating platform to use lights to send warning signals to ships at night.

[0004] The existing safety warning device has the following defects. The water surface height will change in different seasons and weather conditions. For example, in the river, the water depth in the dry season is completely different from that in the rainy season. For example, near the mouth of the Qiantang River, the water depth will change at any time due to the influence of the tide. This requires that the rope has a certain margin and cannot be tightened to ensure that the floating platform continues to remain above the water surface. However, this will cause the floating platform to drift and swing along the water surface with the anchor as the center. The range is large, which cannot accurately reflect the range of the dangerous area, and the use effect is poor. Utility Model Content

[0013] In the aforementioned water transport safety warning device, a steel protective cover is provided in the through hole.

[0014] Compared with the prior art, the utility model adds a rotating shaft to the floating platform on the basis of the existing safety warning device. The floating platform is connected to the anchor through the rotating shaft and the rope on the rotating shaft. The spring of the rotating shaft can tighten the rope at all times, so that a relatively constant tension can be established between the floating platform and the anchor. The drift range of the floating platform on the water surface is small, which can accurately reflect the range of the dangerous area and achieve better use effect. In addition, when the water surface height changes, the buoyancy of the floating platform will also change accordingly, driving the rope to automatically wind or loosen on the rotating shaft, so that the distance between the floating platform and the anchor can be automatically adjusted, ensuring that the floating platform is always above the water surface, and does not affect the function of the safety warning device. In summary, the utility model has the advantage of better use effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0019] Example. Water transport safety warning device, such as Figure 1 As shown, it includes a hollow floating platform 1. The buoyancy generated when the floating platform 1 is sunk into the water as a whole should be greater than 2000N. The floating platform 1 is formed by blow molding as a whole. An anchor 2 sunk to the bottom of the water is provided below the floating platform 1. The anchor 2 is a large-mass reinforced concrete prefabricated block. A rope 3 connected to the anchor 2 is provided on the floating platform 1. The rope is preferably made of a corrosion-resistant polymer material. A rotating shaft 4 made of stainless steel is provided on the floating platform 1. Two baffles 6 are provided on the rotating shaft 4. A rope groove 7 is formed between the two baffles 6. The upper end of the rope 3 is wound in the rope groove 7 of the rotating shaft 4. The rotating shaft 4 is provided with a spring 5 for tightening the rope 3.

[0020] The rotating shaft 4 is tubular, and a first plug 8 is provided at one end of the rotating shaft 4. The first plug 8 is connected to the floating platform 1 through a first bracket 9, and the first plug 8 is rotatably connected to the first bracket 9. A second plug 10 is provided at the other end of the rotating shaft 4, and the second plug 10 is connected to the floating platform 1 through a second bracket 11. The second plug 10 is fixed to the second bracket 11, and the second plug 10 is rotatably connected to the rotating shaft 4. The second plug 10 is connected to the first plug 8 through a spiral spring 5.

[0021] A first sleeve 12 fixed to the rotating shaft 4 is provided on the inner side of the first plug 8 , a first screw 13 is provided on the inner side of the first sleeve 12 , the outer end of the first screw 13 is fixed to the first plug 8 , and the inner end of the first screw 13 is fixed to the spring 5 .

[0022] A second sleeve 14 rotatably connected to the rotating shaft 4 is provided on the inner side of the second plug 10 , and a second screw 15 is provided on the inner side of the second sleeve 14 . The outer end of the second screw 15 is fixed to the second plug 10 , and the inner end of the second screw 15 is fixed to the spring 5 .

[0023] The top of the floating platform 1 is provided with a groove 16, and the rotating shaft 4 is located in the groove 16, so that the top of the floating platform 1 forms a flat installation surface, which is convenient for installing various lighting systems on the installation surface as needed, and at night, the light is used to send warning signals to ships.

[0024] A through hole 17 is provided on the bottom surface of the groove 16, and the through hole 17 is located below the rope groove 7. A steel protective cover 18 is provided in the through hole 17, and the rope 3 passes through the protective cover 18. The protective cover 18 is used to prevent the rope 3 from cutting the floating platform 1, prevent the floating platform 1 from sinking due to water ingress, and improve the service life.

[0025] Working principle: The anchor 2 determines the moving center of the floating platform 1, and at least one-third of the height of the floating platform 1 should be maintained above the water surface. The buoyancy of the water keeps the floating platform 1 above the water surface. The spring 5 has a preload force. The right end of the spring 5 is fixed on the second plug 10. The left end of the spring 5 provides a rotational torque and drives the rotating shaft 4 to rotate through the first plug 8, shrinking the rope 3 so that the rope 3 has a preload force, and the floating range of the floating platform 1 is small. When the water surface rises, the buoyancy of the floating platform 1 increases, overcoming the preload force of the spring 5, causing the rotating shaft 4 to rotate forward, loosening the rope 3, and ensuring that the floating platform 1 continues to remain on the water surface. When the water surface drops, the floating platform 1 drops in height, and the preload force of the spring 5 causes the rotating shaft 4 to rotate in the opposite direction, tightening the rope 3. There is still a preload force between the floating platform 1 and the anchor 2, and the floating range of the floating platform 1 continues to be kept small.
