Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of aquaculture equipment, and particularly relates to a dispersing and cleaning structure of a work ship for offshore mussel harvesting. BACKGROUND

[0002] Mussel, commonly known as sea rainbow, is rich in nutritional value and is a high-protein food. The common cultivation method of mussel is offshore cultivation, i.e. the marine ranching mode. Generally, pile heads are first installed on the seabed, and then connecting ropes, floating ropes, lifting ropes and growing ropes are sequentially arranged, and finally mussels can be cultivated on the growing ropes. Among them, floating balls are generally arranged on the floating ropes, and reinforcing ropes are further arranged between the mutually parallel floating ropes.

[0003] On the other hand, the starting point of mussel harvesting operation is to lift the floating rope and release the growing rope from the lifting rope. The relatively traditional mussel harvesting method is to transport all the growing ropes back to the shore, and then perform subsequent operations such as unloading, cleaning, screening and bagging. This method has the problems of low efficiency and serious environmental pollution.

[0004] Therefore, more advanced and efficient work ships for offshore harvesting have appeared, which mainly include a rope pulling device, a separating device, a cleaning device, a screening device and a bagging device. Although the specific process steps are basically the same, the offshore, integrated and automated operation method is highly efficient, which is very critical for the concentrated harvesting period of mussels.

[0005] In addition, even in the above traditional mussel harvesting method, a cleaning structure is used, which has the basic function of dispersing the clustered mussels and cleaning each mussel as much as possible to remove the dirt and algae on the mussels.

[0006] For example, the Chinese utility model patent with the authorization announcement number CN216796352U and the authorization announcement date of June 24, 2022 discloses an environmentally friendly mussel rapid cleaning device, which includes a box body, a nozzle, and a cleaning assembly. The cleaning assembly includes a first cleaning box, a rotating shaft and a rotary driver. The first cleaning box is rotatably installed in the box body. A plurality of first cleaning boxes are arranged at equal distances on the first cleaning box. The first cleaning box is arrayed with mud permeable holes. The rotating shaft is rotatably installed on the box body. The first cleaning box is sleeved on the rotating shaft. The rotary driver is fixedly installed at the bottom of the box body. The driving end of the rotary driver is in transmission connection with the rotating shaft.

[0007] The mussel rapid cleaning device in the utility model patent has the following general advantages: the box body and the cleaning assembly achieve the purpose of rapidly cleaning mussels while ensuring that the mussels are not damaged.

[0008] However, the mussel rapid cleaning device has at least the following two deficiencies in actual use, which are also the technical problems to be solved by the present application, namely:

[0009] Firstly, the active cleaning intensity is relatively low, and only the bristles rotating with the first cleaning box can directly brush the mussels, which is far from enough, and it is more difficult to separate the mussels in groups;

[0010] Secondly, in order to clean the inner side of the box, the device is additionally equipped with a motor driver, which greatly increases the production and use cost of the device.

[0011] Therefore, in summary, there is an urgent need for a new cleaning device with relatively high cleaning intensity and simple and convenient cleaning method of the inner side itself, for use in dispersing and cleaning the mussels unloaded from the cultivation rope. SUMMARY

[0012] The present application provides a dispersing and cleaning structure of a work ship for offshore mussel harvesting, which can rotate the rotating column unit and the horizontal cylinder unit, so that the active cleaning intensity of the mussels is relatively large, the mussels can be dispersed and cleaned, and the rotating cover unit can be rotated to expose the inner side to be cleaned, so that the cleaning operation of the rotating cover unit is simple and convenient, and no additional electrical equipment is needed.

[0013] The technical scheme adopted by the present application to solve the above problems is: a dispersing and cleaning structure of a work ship for offshore mussel harvesting, comprising a fixed frame and a support column, a rotating column unit arranged on the fixed frame and used for vertically agitating mussels, a horizontal cylinder unit sleeved on the rotating column unit and used for loading mussels and discharging sewage, a rotating cover unit hingedly arranged on one side of the fixed frame and used for covering the horizontal cylinder unit, and a water pipe unit arranged on the fixed frame and used for flushing the mussels in the horizontal cylinder unit.

[0014] Further preferred technical scheme is that the rotating column unit comprises a rotating horizontal shaft and a column body arranged on the rotating horizontal shaft and used for agitating mussels.

[0015] Further preferred technical scheme is that the horizontal cylinder unit comprises a support ring sleeved on the rotating horizontal shaft, a connecting column arranged on the support ring, a spacing rod body arranged on the connecting column and used for supporting mussels and discharging sewage, and a fixed ring arranged on the spacing rod body.

[0016] Further preferably, the lateral cylinder unit further comprises a one-way bearing arranged between the lateral rotating shaft and the supporting ring.

[0017] Further preferably, the rotating cover unit comprises a reversed U-shaped plate arranged on the fixed frame and having openings facing downward, and covering the lateral cylinder unit, and side edge hinges arranged on the fixed frame and the reversed U-shaped plate.

[0038] The following description is only a preferred embodiment of the application, and does not limit the scope of the application.

[0039] As shown in the accompanying drawings, Figures 1-8 A dispersing and cleaning structure of a work ship for offshore mussel harvesting, comprising a fixed frame 11 and a support column 12, further comprising a rotary column unit 1 arranged on the fixed frame 11 and used for vertically agitating mussels, a transverse cylinder unit 2 telescopically arranged on the rotary column unit 1 and used for loading mussels and discharging sewage, a rotary cover unit 3 hingedly arranged on one side of the fixed frame 11 and used for covering the transverse cylinder unit 2, and a water pipe unit 4 arranged on the fixed frame 11 and used for flushing mussels in the transverse cylinder unit 2.

[0040] In this embodiment, the fixed frame 11 and the support column 12 are generally not in contact with seawater, so their material is general 304 stainless steel, while the rotating column unit 1, the transverse cylinder unit 2, the rotating cover unit 3 and the water pipe unit 4 are directly in contact with seawater, so the main material of the four is 316 stainless steel with outstanding corrosion resistance.

[0041] The support column 12 is screwed with the hull deck, and a bottom rectangular frame is further arranged thereon, so that the installation structure of the fixed frame 11 has higher stability, and the scattering and cleaning structure is prevented from swinging greatly during normal use.

[0042] In addition, the scattering and cleaning structure is of a horizontal type, and its gravity center is relatively low, so it is more suitable for use on a ship. The rotating column unit 1 is horizontally arranged, and the rotating direction is vertical, which is used for scattering the clustered mussels and fully cleaning all the mussels.

[0043] The transverse cylinder unit 2 is also horizontally arranged, and the rotating shaft position of the rotating column unit 1 is the center axis position of the transverse cylinder unit 2. On the other hand, the transverse cylinder unit 2 can also rotate, which directly affects the turning of the mussels and indirectly affects the increase of the scattering and cleaning strength. The first mode of the rotation of the transverse cylinder unit 2 is external power input, including external driving belt or manual pushing.

[0044] The main function of the rotating cover unit 3 is to prevent water from splashing outward when the rotating column unit 1 is opened and rotated and the water pipe unit 4 is opened and flushed, otherwise a large amount of water will accumulate on the deck of the work ship, which is not conducive to the safety of the on-site operators. Correspondingly, the support column 12 is further provided with the water receiving groove 14, so that the sewage falling on the transverse cylinder unit 2 and the rotating cover unit 3 can be received and discharged into the sea in a centralized and orderly manner, avoiding the flow of sewage on the work ship.

[0045] On the other hand, the rotating cover unit 3 is installed in a mode of one-side hinging and the other-side direct placement. Therefore, it has the characteristics of convenient opening and the inner side being fully exposed upward, which facilitates the cleaning operation of the inner side without the need for additional electrification equipment, simplifies the scattering and cleaning structure, and reduces the production and use cost.

[0046] The water pipe unit 4 uses seawater, and its function is to separate the cleaning dirt and the mussels as soon as possible and thoroughly.

[0047] Finally, the support column 12 is further provided with the discharging groove 13, and the mussels falling thereon meet the requirements of the screening operation and do not appear the phenomenon of multiple mussels being combined into a cluster.

[0048] The rotating column unit 1 comprises a rotating horizontal shaft 101 and a column 102 arranged on the rotating horizontal shaft 101 and used for stirring mussels.

[0049] In the embodiment, the rotating horizontal shaft 101 and the column 102 are fixed and perpendicular to each other, and the column 102 is used for directly stirring mussels.

[0050] Specifically, 3-5 groups of the columns 102 are arranged on the rotating horizontal shaft 101 in length, and each group comprises 3-4 columns 102, and the columns in different groups and the columns in the same group are arranged at uniform intervals.

[0051] The horizontal cylinder unit 2 comprises a support ring 201 arranged on the rotating horizontal shaft 101 in a sleeved manner, a connecting column 202 arranged on the support ring 201, a spacing rod 203 arranged on the connecting column 202 and used for supporting mussels and discharging sewage, and a fixed ring 204 arranged on the spacing rod 203.

[0052] In the embodiment, the cleaning sewage falls and is discharged between any two adjacent spacing rods 203. The number of the fixed rings 204 is 3-8, each of the fixed rings 204 connects all the spacing rods 203, and the cylindrical structure of the horizontal cylinder unit 2 is ensured to be stably and rotationally operated. The connecting mode between the spacing rod 203 and the fixed ring 204 is welding, or welding plus insertion, or welding plus clamping connection.

[0053] In addition, 3-5 groups of the connecting columns 202 are arranged on the rotating horizontal shaft 101 in length, and each group comprises 3-4 connecting columns 202, so that the horizontal cylinder unit 2 is relatively immobile in vertical and horizontal positions compared with the rotating horizontal shaft 101, and the horizontal cylinder unit 2 can only rotate.

[0054] The horizontal cylinder unit 2 further comprises a one-way bearing arranged between the rotating horizontal shaft 101 and the support ring 201.

[0055] In the embodiment, the second mode of self-rotation of the horizontal cylinder unit 2 is that, by means of the one-way bearing and the function that the rotating horizontal shaft 101 can rotate in forward and reverse directions, when the rotating horizontal shaft 101 rotates in one direction, the rotating horizontal shaft 101 and the support ring 201 are disconnected, and the two are “offline”, and when the rotating horizontal shaft 101 rotates in the reverse direction, the one-way bearing is connected, and the horizontal cylinder unit 2 can rotate like the column 102.

[0056] Generally, the first rotation direction is the normal operation of the rotating horizontal shaft 101, and the duration of the reverse rotation operation is short, so that the mussel stirring cleaning effect is mainly achieved by the column 102 and supplemented by the horizontal cylinder unit 2.

[0057] On the other hand, after the one-way bearing is installed, the horizontal cylinder unit 2 can still be rotated by external power or manually as needed for quick discharge of accumulated sewage inside and on the horizontal cylinder unit 2.

[0058] The rotating cover unit 3 includes a reversed U-shaped plate 301 with both ends arranged on the fixed frame 11 and opening downward, and used to cover the horizontal cylinder unit 2, and a side edge hinge 302 arranged on the fixed frame 11 and the reversed U-shaped plate 301.

[0059] In this embodiment, the reversed U-shaped plate 301 has its opening downward during normal use, and its vertical projection covers the entire horizontal cylinder unit 2, ensuring that at least the sewage splashed on the horizontal cylinder unit 2 above the fixed frame 11 is completely blocked by the reversed U-shaped plate 301, avoiding pollution of the operating environment of the workboat.

[0060] When the dispersing and cleaning structure is idle, the side of the reversed U-shaped plate 301 without the side edge hinge 302 is lifted upward, and the opening of the former faces upward, exposing the inner side to be cleaned. Washing the inner side and orderly discharging the cleaning sewage can make the cleaning effect of the rotating cover unit 3 simple and efficient without the need for additional electrical equipment.

[0061] On the other hand, the rotating cover unit 3 has the structural feature of "dividing the whole into parts", which includes 2-3 reversed U-shaped plates 301, so that the rotating cover unit 3 can both completely cover the horizontal cylinder unit 2 and reduce the weight of a single reversed U-shaped plate 301, making the manual rotation operation of the reversed U-shaped plate 301 relatively labor-saving.

[0062] The water pipe unit 4 includes a horizontal pipe 401 arranged on the support column 12 and located outside the horizontal cylinder unit 2, and a nozzle 402 arranged on the horizontal pipe 401.

[0063] In this embodiment, the height of the horizontal pipe 401 is lower than that of the fixed frame 11 and higher than that of the water trough body 14. In addition, most of the horizontal cylinder unit 2 is located above the fixed frame 11, but the small part located below the fixed frame 11 is the main position for holding mussels and discharging sewage. At least one row of nozzles 402 can perform efficient and targeted washing operations on the above-mentioned main position.

[0064] In addition, the transverse pipe 401 is externally connected with a water pump, and a switch valve is arranged on the water pump as needed.

[0065] The water pipe unit 4 further comprises a vertical pipe 403 arranged on the transverse pipe 401, a transversely extending pipe 404 arranged on the vertical pipe 403, and an inclined flushing pipe 405 arranged on the transversely extending pipe 404 and extending into the transverse cylinder unit 2.

[0066] In the embodiment, the nozzles 402 are outside the transverse cylinder unit 2, and the main flushing object is the transverse cylinder unit 2. The inclined flushing pipe 405 extends into the transverse cylinder unit 2, and the main flushing object is the mussels, so that the dispersing and cleaning effect of the water pipe unit 4 is more thorough.

[0067] The number of the inclined flushing pipes 405 is two, which are respectively arranged at the left and right opening positions of the transverse cylinder unit 2, and the flushing outlets thereof are downward, for directly dispersing and cleaning the mussels.

[0068] The water pipe unit 4 further comprises rotatable pipe joints 406 arranged at the two end positions of the transversely extending pipe 404 respectively, and the transversely extending pipe 404 and the inclined flushing pipe 405 are rotated by the rotatable pipe joints 406, for flushing the inner side of the inverted U-shaped plate 301 which has been rotated to be open.

[0069] In the embodiment, the two rotatable pipe joints 406 are used in combination, and the functions are as follows:

[0070] Firstly, the transversely extending pipe 404 can be transversely rotated, that is, the inclined flushing pipe 405 can enter and exit the transverse cylinder unit 2.

[0071] Secondly, the inclined flushing pipe 405 can be vertically rotated, and the relatively central position inside the transverse cylinder unit 2 can also be flushed.

[0072] More importantly, the dispersing and cleaning structure is idle, that is, when the rotating column unit 1 is stopped, the inverted U-shaped plate 301 is rotated upward to the inner side thereof being upward, and the two rotatable pipe joints 406 are rotated, so that the inclined flushing pipe 405 is directed to the inverted U-shaped plate 301, and the end and middle of the inner side of the inverted U-shaped plate 301 can be flushed, so that the cleaning operation of the inner side of the inverted U-shaped plate 301 is ensured, and the water pipe does not need to be additionally used, which is very simple and efficient.

[0073] After the cleaning of the inverted U-shaped plate 301 is completed, the transversely extending pipe 404 and the inclined flushing pipe 405 are rotated again, and the latter is located in the transverse cylinder unit 2.

[0074] In addition, the height of the transverse extension pipe 404 and the inclined flushing pipe 405 is higher than the height of the bottom edge of the transverse barrel unit 2, so that the mussels cleaned will not bump into the above-mentioned two pipe bodies when discharging. At the feeding end of the transverse barrel unit 2, the positions of the transverse extension pipe 404 and the inclined flushing pipe 405 are relatively close to the edge, so that the mussels to be dispersed and cleaned will not bump into the above-mentioned two pipe bodies when adding the feed. For details, please refer to the attached drawings. Figure 5 .

[0075] The transverse barrel unit 2 further comprises a reinforcing plate 205 arranged at the end of the connecting column 202 and used for connecting the spacing rod body 203 and the fixed ring 204, and a ring-shaped connecting protrusion 206 arranged on the spacing rod body 203.

[0076] In the embodiment, the main function of the reinforcing plate 205 is to reinforce the connection of all the fixed rings 204 and the adjacent spacing rod bodies 203 in the length direction of the transverse barrel unit 2.

[0077] The main function of the ring-shaped connecting protrusion 206 is to connect and reinforce the adjacent 2-3 spacing rod bodies 203 in a “point-like” manner in the ring direction of the transverse barrel unit 2.

[0078] On the other hand, the reinforcing plate 205 and the ring-shaped connecting protrusion 206 have the following secondary functions: relative to a ring of the spacing rod bodies 203, they are protruded and can improve the stirring intensity of the mussels, and finally improve the dispersion and cleaning effect of the mussels.

[0079] The rotating column unit 1 further comprises a barrel length direction connecting plate 103 arranged at the end of the column body 102 and used for stirring the mussels and pushing the reinforcing plate 205 in the ring direction, and a stepping motor 104 arranged on the rotating transverse shaft 101.

[0080] In the embodiment, the third rotating mode of the transverse barrel unit 2 is that the rotating area of the barrel length direction connecting plate 103 and the reinforcing plate 205 partially overlaps, that is, they can properly resist, collide and push each other, so that the stepping motor 104 can indirectly drive the transverse barrel unit 2 to rotate, which is finally beneficial to the dispersion and cleaning effect of the mussels.

[0081] The position relationship and function between the barrel length direction connecting plate 103 and the reinforcing plate 205 do not conflict with the one-way bearing, and both can be arranged and used.

[0082] Finally, it should be noted that:

[0083] First, two ends of the rotating horizontal shaft 101 are connected with the step motor 104 and the mounting bearing 105 respectively, and the latter two are mounted on two wide side plates of the rectangular fixed frame 11 respectively;

[0084] Second, the rotating horizontal shaft 101 and the horizontal cylinder unit 2 are parallel to each other and are both inclined, the inclined upper end of the latter is the mussel feeding position, and the inclined lower end of the latter is the mussel discharging position, and the discharging groove body 13 is mounted on the side of the discharging position;

[0085] Third, the outer side of the inverted U-shaped plate 301 is further provided with the rotating handle 303;

[0086] Fourth, both ends of the inverted U-shaped plate 301 are provided with the water blocking side plate 304, the shape of the water blocking side plate 304 is semicircular or U-shaped, and the secondary function is to block the accidental splashing of sewage during scattering and cleaning, and the main function is:

[0087] When the inner side of the inverted U-shaped plate 301 faces upwards and is cleaned, the cleaning water is retained in the inverted U-shaped plate 301, that is, the water body is blocked by the two water blocking side plates 304, at this time, the inverted U-shaped plate 301 is relatively rotated and reset, so that the above-mentioned cleaning water is poured into the water receiving groove 14, which saves an additional cleaning water collecting and discharging structure, or makes the above-mentioned cleaning water which is originally randomly discharged be collected and orderly discharged, avoiding pollution of the work ship, which is very ingenious and practical.

[0088] The embodiments of the application are described in detail above in combination with the drawings, but the application is not limited to the above-mentioned embodiments, and various modifications can be made within the knowledge of ordinary skilled in the art without departing from the purpose of the application. These are not creative modifications, and as long as they are within the scope of the claims of the application, they are protected by the patent law.
