Description

Technical Field

[0001] The present invention relates to the technical field of water surface garbage cleaning, and in particular to a water surface garbage cleaning vessel capable of purifying water quality and a cleaning method thereof. Background Art

[0002] In order to keep the sea surface environment clean, it is usually necessary to manually salvage surface garbage from the water surface and then clean up the surface garbage. In order to improve the efficiency of garbage cleaning, surface garbage cleaning ships are used.

[0003] Surface garbage cleaning boats are mainly used to collect floating garbage on the surface of water bodies. For example, the Chinese invention patent with announcement number CN109501974B provides a surface garbage cleaning boat that collects garbage into a garbage storage box through brushes and steel mesh. The garbage storage box uses a grid box with a drainage effect.

[0004] However, existing surface garbage cleaning ships will collect large-volume garbage while the sewage collected with the garbage will flow back into the water body, causing water pollution. They are also unable to effectively clean up tiny pollutants such as microplastics and suspended particles in the sewage. Some improvement plans have attempted to add filters or adsorption modules, but they are often difficult to put into practical use due to complex structures, clogged filter holes or excessive energy consumption.

[0005] Existing technologies cannot simultaneously address the dual needs of garbage salvage and water purification, especially in ecologically sensitive waters.

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] Example 1 refer to Figure 1 The present invention provides a surface garbage cleaning ship capable of purifying water quality, comprising a hull 100, a garbage cleaning device, a garbage compression unit 200 and a sewage separation unit 300. The garbage cleaning device comprises a garbage salvaging unit 400 and two salvaging baffles 500; the two salvaging baffles 500 are respectively arranged on the left and right sides of the front end of the hull 100 and are movably connected to the hull 100, the garbage salvaging unit 400 is arranged between the two salvaging baffles 500 and is connected to the hull 100, the input end of the garbage salvaging unit 400 is close to the bottom of the hull 100 and extends into the water body, the output end of the garbage salvaging unit 400 is located above the garbage compression unit 200, and the garbage salvaging unit 400 is provided with a plurality of garbage compressing units 200, and the garbage compressing units 200 are provided with a plurality of garbage compressing units 200. 400 is tilted, and the garbage compression unit 200 is arranged on the hull 100 and is located at the rear end of the hull 100. It is used to salvage surface garbage during transmission and then transport it to the garbage compression unit 200 for compression and collection. The two salvage baffles 500 are used to adjust the deflection angle to increase the garbage salvage and collection range, thereby realizing the cleaning of solid garbage; the sewage separation unit 300 arranged on the hull 100 extracts sewage containing suspended matter, microplastics and other small-volume pollutants through the water inlet end, and then filters and removes the pollutants through the sewage separation unit 300, discharges the purified water back into the water body, and injects the sewage containing pollutants into the hull 100 for storage.

[0025] Example 2 refer to Figure 2 Based on Example 1, this embodiment provides a surface garbage cleaning ship that can purify water quality. The hull 100 includes a load-bearing ship plate 110, a truss 120 and two load-bearing ships 130. The two load-bearing ships 130 are arranged in the same direction on the left and right sides of the load-bearing ship plate 110. The load-bearing ship plate 110 is connected to the load-bearing ships 130 through the truss 120. A gap is reserved between the two load-bearing ships 130. Preferably, a reserved opening for accommodating a garbage compression unit 200 is opened on the load-bearing ship plate 110 and the truss 120 to increase the volume of the garbage compression unit 200.

[0026] For further explanation, see Figure 3The carrier ship 130 includes a hull 140, a cabin cover 141, a propeller 142, a propulsion motor 143, a rear cabin battery 144 and a front cabin battery 145. The interior of the carrier ship 130 is provided with a blade drive cabin 131, a power cabin 132 and a sewage collection cabin 133. The hull 140 is streamlined, and the hull 140 and the cabin cover 141 are made of TPX material. At this time, the weight of the carrier ship 130 can be selected as 0.78 kg, and the weight of the cabin cover 141 can be selected as 0.34 kg.

[0027] The propeller 142 is arranged on the outside of the tail of the hull 140, and the propulsion motor 143 is arranged in the blade drive compartment 131 and is transmission-connected to the propeller 142. There are two power compartments 132, one power compartment 132 is close to the front end of the hull 140, and the other power compartment 132 is located between the sewage collection compartment 133 and the power compartment 132. The rear compartment battery 144 and the front compartment battery 145 are respectively arranged in the corresponding power compartments 132 for powering the entire ship; the sewage collection compartment 133 is located between the two power compartments 132.

[0028] The cabin cover 141 covers the top of the hull 140, and the propeller drive compartment 131, the power compartment 132 and the sewage collection compartment 133 are all connected by partitions between the cabin cover 141 and the hull 140 to form a sealed space.

[0029] Among them, the sewage collecting cabin 133 is preferably divided into a sewage storage chamber 133a and a collection cavity 133b by an internally arranged water storage baffle 134. The sewage storage chamber 133a is close to the front cabin battery 145. The cross-sectional area of the sewage storage chamber 133a increases from bottom to top. The sewage outlet end of the sewage separation unit 300 passes through the collection cavity 133b and is connected to the sewage storage chamber 133a. A sewage outlet 135 is provided at the bottom of the hull 140, and the sewage outlet 135 is connected to the sewage storage chamber 133a.

[0030] By optimizing the shape of the sewage storage chamber 133a, the center of gravity of the hull 100 can be kept basically balanced when loading garbage of different weights and purified sewage of different volumes.

[0031] refer to Figure 4 , with reference to the coordinate system zox, when the depth of purified sewage is 40mm, the depth of compressed garbage is 40mm, and the x, y, z coordinates of the center of gravity are 3.935, 0.813, 62.320); when the depth of purified sewage is 80mm, the depth of compressed garbage is 80mm, and the x, y, z coordinates of the center of gravity are 3.571, -0.788, 60.752); when the depth of purified sewage is 180mm, the depth of compressed garbage is 180mm, and the device reaches the maximum load, and the x, y, z coordinates of its center of gravity are 5.516, -0.709, 56.447).

[0032] Refer to Table 1 for the center of gravity position at different garbage loads and purified sewage depths.

[0033] Table 1 Center of gravity of the hull under different loads and depths of purified sewage

[0034] When the garbage load depth is 20mm and the purified sewage depth is 40mm, the center of gravity decreases by 0.505mm in the x-axis direction and by 0.889mm in the z-direction compared to a zero load. As the garbage load depth and purified sewage depth increase, the center of gravity gradually shifts leftward and decreases. When the garbage load depth reaches 60mm and the sewage depth reaches 80mm, the center of gravity shifts to the left to its maximum. As more garbage and purified sewage are added, the center of gravity gradually shifts forward and to the right. This is because the small volume at the bottom of sewage storage chamber 133a cannot fully offset the weight of the garbage. As the depth of sewage storage chamber 133a increases, it gradually offsets the weight of the compressed garbage.

[0035] Refer to Table 2 for the center of gravity position table under the same garbage load and purified sewage depth.

[0036] Table 2 Center of gravity position under the same load and purified sewage depth

[0037] When the depth is 40 mm, the center of gravity shifts to the left by 1.575 mm and drops by 0.986 mm. When the depth is 80 mm, the center of gravity shifts to the left, reaching a maximum of 1.939 mm. As the depth increases, the center of gravity shifts to the right and gradually returns to its original position. At a depth of 180 mm, the center of gravity shifts by 0.006 mm in the x-direction, 0.123 mm in the y-direction, and 0.123 mm in the z-direction compared to the zero-load center of gravity. During this process, the center of gravity gradually decreases. As can be seen from the above, by controlling the amount of purified wastewater in the wastewater storage chamber 133a, the center of gravity of the hull 100 can be adjusted to ensure the stability of the hull 100 in the water.
