Description

Technical Field

[0001] The utility model relates to the technical field of seawater aquaculture, in particular to a seawater sterilization device for seawater aquaculture. Background Art

[0002] Mariculture is an important part of marine fisheries and is of great significance in promoting the sustainable development of the fishery economy, enriching the market supply of aquatic products, and increasing the income of fishermen. At the same time, with the increasing demand for healthy food, the market demand for mariculture products is also expanding. Marine fish are raised in circulating water through land-based aquaculture ponds or seawater controllers. This method requires the use of a pump to draw seawater into the pool, then clean and disinfect it through a filtration system, and finally discharge it back into the ocean or recycle it.

[0003] A seawater sterilization device for seawater aquaculture is a seawater disinfection device, which uses aeration technology and ultraviolet sterilization devices as sterilization devices in seawater aquaculture. The aeration device mainly achieves the purpose of sterilization and improving water quality by increasing the dissolved oxygen content in the water body and stirring the water body. Ultraviolet sterilization is instant, that is, when seawater flows through the sterilization pipe, ultraviolet light can immediately kill the bacteria it contacts.

[0004] The ultraviolet sterilization devices in the existing technology mainly rely on ultraviolet light to directly irradiate the surface of bacteria and destroy their DNA or RNA structure to achieve a sterilization effect. However, this sterilization method is only effective in areas where ultraviolet light can directly irradiate. For shadow areas in seawater, dead corners of water flow, or deep areas where bacteria gather, ultraviolet light may not be able to fully irradiate, resulting in unsatisfactory sterilization effect. Therefore, a seawater sterilization device for seawater aquaculture is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem raised in the background technology, the present invention proposes a seawater sterilization device for seawater aquaculture.

[0008] Preferably, a plurality of connecting columns are installed on the driving shaft; and three stirring rods are installed on the connecting columns.

[0009] Preferably, support plates are fixedly connected on both sides of the bottom of the base plate; an adjustment component is installed at the bottom of the support plate; the adjustment component includes a threaded sleeve, and the top of the threaded sleeve is rotatably connected to the bottom of the support plate; the threaded sleeve is internally threaded with a screw rod 1; the bottom of the screw rod 1 is fixedly connected to the support base.

[0010] Preferably, a motor protection shell is detachably mounted on the bottom plate, and the driving motor is arranged in the motor protection shell.

[0011] Preferably, three snap-fitting slots are provided in the blower, and filter plates are slidably connected in two of the snap-fitting slots.

[0012] Preferably, an ultraviolet lamp is installed on the outer side of the support plate; and two floating blocks are installed on the bottom of the base plate.

[0013] The utility model is beneficial in that:

[0014] 1. The utility model discloses a seawater sterilization device for seawater aquaculture. When the aeration sterilization effect is not good, the device can switch to the ozone sterilization mode. Ozone is a strong oxidant that can quickly destroy the cell walls and DNA of bacteria, thereby achieving the purpose of efficient sterilization. Compared with single ultraviolet sterilization, ozone sterilization has a wider sterilization spectrum and stronger sterilization ability.

[0015] 2. The utility model describes a seawater sterilization device for seawater aquaculture, which combines the two functions of aeration oxygenation and ozone sterilization to form a multiple sterilization barrier. During the aeration process, although the main purpose is to increase oxygen, it can also stir the water to a certain extent, so that bacteria can come into more complete contact with oxygen or ozone, thereby improving the sterilization effect. At the same time, ozone sterilization, as an auxiliary means, can make up for the shortcomings of aeration sterilization and ensure that pathogens in seawater are effectively controlled.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-5As shown, a seawater sterilization device for seawater aquaculture includes a base plate 1; the characteristics are: the base plate 1 is provided with an aeration assembly 3; the aeration assembly 3 includes a hydraulic rod 31; two hydraulic rods 31 are provided, and the top of the hydraulic rod 31 is fixedly connected to the bottom of the base plate 1; two groups of connecting square rods 32 are fixedly connected to the bottom of the hydraulic rod 31, and each group of connecting square rods 32 is provided with two; an aeration pipe 33 is installed at the bottom of the connecting square rod 32; a plurality of aeration heads 34 are provided on the aeration pipe 33; one of the connecting square rods 32 is connected to a connecting bellows 35; the top of the connecting bellows 35 passes through the end of the base plate 1 and is connected to a blower 36; the blower 36 is connected to an ozone generator 38; a stirring assembly 4 is provided on the base plate 1; During operation, the blower 36 injects oxygen from the air into the connecting bellows 35, which is then transferred to the connecting square rod 32. The oxygen is then transferred to the aeration pipe 33 by the connecting square rod 32, and then injected into the seawater through the aeration head 34 on the aeration pipe 33, thereby increasing the dissolved oxygen content in the water body. The hydraulic rod 31 then drives the aeration pipe 33 connected to the connecting square rod 32 to move up and down, so that the aeration head 34 on the aeration pipe 33 can supply oxygen to water surfaces at different heights. The hydraulic rod 31 enables the aeration pipe 33 to move up and down, thereby supplying oxygen and ozone to water surfaces at different heights. This flexibility ensures that the device can adapt to aquaculture ponds of different depths and provide uniform oxygen and sterilization effects for the entire water body.

[0025] When the aeration sterilization effect is not good, the ozone gas produced is transmitted to the blower 36 through the ozone generator 38, and then the blower 36 sends the produced ozone gas into the connecting bellows 35, and then blown into the aeration pipe 33 by the connecting square rod 32 connected to the connecting bellows 35, and then sprayed out by the aeration head 34 on the aeration pipe 33, thereby sterilizing the seawater with ozone; when the aeration sterilization effect is not good, the device can switch to the ozone sterilization mode. Ozone is a strong oxidant that can quickly destroy the cell walls and DNA of bacteria, thereby achieving the purpose of efficient sterilization. Compared with single ultraviolet sterilization, ozone sterilization has a wider sterilization spectrum and stronger sterilization ability.

[0026] Further, such as Figure 1-3As shown, the stirring assembly 4 includes a drive motor 41; the output shaft of the drive motor 41 is fixedly connected to the drive shaft 42, and the top end of the drive shaft 42 is rotatably connected to the bottom plate 1; the bottom end of the drive shaft 42 is slidably connected to the connecting square rod 32; a plurality of connecting columns 43 are installed on the drive shaft 42; and three stirring rods 44 are installed on the connecting column 43; when working, the drive motor 41 drives the drive shaft 42 to rotate, the drive shaft 42 drives the connecting column 43 to rotate, and the connecting column 43 drives the stirring rod 44 connected thereto to rotate, thereby stirring the seawater, thereby improving its sterilization effect during aeration sterilization; the stirring assembly 4 drives the drive shaft 42 to rotate through the drive motor 41, thereby driving the connecting column 43 and the stirring rod 44 to rotate in the seawater. This stirring action can effectively stir the water body, so that the oxygen or ozone gas ejected by the aeration head 34 can be more evenly distributed throughout the water body, reducing the problem of excessive oxygen or ozone concentration in local areas and insufficient concentration in other areas, thereby improving the uniformity and effect of aeration sterilization.

[0027] Further, such as Figure 1 、 5 As shown, the bottom sides of the bottom of the bottom plate 1 are fixedly connected to the support plates 2; the bottom of the support plate 2 is installed with an adjustment component 7; the adjustment component 7 includes a threaded sleeve 71, and the top of the threaded sleeve 71 is rotatably connected to the bottom of the support plate 2; the threaded sleeve 71 is internally threaded with a screw 1 72; the bottom of the screw 1 72 is fixedly connected to a support base 73; when working, the threaded sleeve 71 is rotated, and the threaded sleeve 71 rotates at the bottom of the support plate 2, and then rotates on the screw 1 72, thereby adjusting the overall height of the device. By rotating the threaded sleeve 71, due to its threaded connection relationship with the screw 1 72, the overall height of the device can be easily adjusted. This enables the device to adapt to the needs of different water depths and aquaculture environments, thereby improving the adaptability and flexibility of the device.

[0028] Further, such as Figure 1 、 2 As shown, a motor protection shell 8 is detachably mounted on the base plate 1 , and the drive motor 41 is arranged in the motor protection shell 8 ; during operation, the motor protection shell 8 can reduce water vapor erosion of the drive motor 41 and cause damage to the drive motor 41 .

[0029] Further, such as Figure 1 、 4 As shown, three snap-in slots 9 are provided in the blower 36, and filter plates 37 are slidably connected in two of the snap-in slots 9; when working, the filter plates 37 can filter the air blown out of the blower 36, thereby reducing the dust from entering the aeration head 34 and clogging the aeration head 34. The snap-in slots 9 can snap the filter plates 37, and when replacing, the filter plates 37 can be snapped into the snap-in slots 9 to replace the filter plates 37.

[0030] Further, such as Figure 1 、 2 As shown, an ultraviolet lamp 5 is installed on the outer side of the support plate 2; two floating blocks 6 are installed at the bottom of the base plate 1; when working, the ultraviolet lamp 5 assists the aeration component 3 in sterilization to improve the sterilization effect, and the floating blocks 6 can make the device float when encountering a water level higher than the device, reducing the impact of water vapor on internal components.

[0031] Working principle: when working, the blower 36 injects oxygen in the air into the connecting bellows 35, which is then transmitted to the connecting square rod 32 by the connecting bellows 35, and then transmitted to the aeration pipe 33 by the connecting square rod 32, and then the oxygen in the air is injected into the seawater through the aeration head 34 on the aeration pipe 33, thereby increasing the dissolved oxygen content in the water body, and then the hydraulic rod 31 drives the aeration pipe 33 connected to the connecting square rod 32 to move up and down, so that the aeration head 34 on the aeration pipe 33 can supply oxygen to water surfaces at different heights, and the hydraulic rod 31 enables the aeration pipe 33 to move up and down, thereby supplying oxygen and ozone to water surfaces at different heights. This flexibility ensures that the device can adapt to aquaculture ponds of different depths and provide uniform oxygen and sterilization effect for the entire water body; when the aeration sterilization effect is not good, the ozone gas produced by the ozone generator 38 is transmitted to the blower 36, and then the blower 36 sends the produced ozone gas into the connecting bellows 35, and then the connecting bellows The connecting square rod 32 connected to the tube 35 blows into the aeration pipe 33, and then is sprayed out by the aeration head 34 on the aeration pipe 33, thereby sterilizing the seawater with ozone; when the aeration sterilization effect is not good, the device can switch to the ozone sterilization mode. Ozone is a strong oxidant that can quickly destroy the cell walls and DNA of bacteria, thereby achieving the purpose of efficient sterilization. Compared with single ultraviolet sterilization, ozone sterilization has a wider sterilization spectrum and stronger sterilization ability; when working, the drive motor 41 drives the drive shaft 42 to rotate, the drive shaft 42 drives the connecting column 43 to rotate, and the connecting column 43 drives the stirring rod 44 connected thereto to rotate, thereby stirring the seawater, thereby improving its sterilization effect during aeration sterilization; when working, the threaded sleeve 71 is rotated, and the threaded sleeve 71 rotates at the bottom of the support plate 2, and then rotates on the screw 1 72, thereby adjusting the overall height of the device. By rotating the threaded sleeve 71, due to its threaded connection relationship with the screw 1 72, the overall height of the device can be conveniently adjusted.
