Description

Technical Field

[0001] The present invention relates to the technical field of polar ocean scientific research, and in particular to a retracting and deploying auxiliary device suitable for an under-the-ship probing device of an icebreaker and a use method thereof. Background Art

[0002] Scientific research vessels are often equipped with underwater omnidirectional sonar for detecting fishery resources, ultra-short baselines for underwater positioning and other down-penetrating equipment. When in use, such equipment is lowered to the position below the bottom of the ship through hydraulic or electric lifting rods for detection; when not in use, it is recovered into the hull through hydraulic or electric lifting rods. Some ships that transport oil, hazardous chemicals and sail in ice areas usually use a double-layer bottom structure to ensure maximum safety. This means that after the down-penetrating equipment is recovered into the hull, the distance from the second layer of the bottom is relatively large.

[0003] In the field of polar scientific research, icebreakers are equipped with diving equipment to detect the ocean. In polar floating ice areas, there are many problems with the use of diving equipment. Figure 1 As shown in the figure, in polar regions, after the diving equipment is recovered into the hull, when the icebreaker is breaking ice, floating ice will gather in the cylindrical cavity between the diving equipment and the second bottom of the ship, and large pieces of floating ice will hit the diving equipment, causing damage to the diving equipment. When the diving equipment descends to the lower part of the ship bottom through the hydraulic or electric lifting rod, it will also hit the floating ice first, causing damage. Figure 2 As shown, during the recovery process of the diving equipment, floating ice will enter the space area of ​​the cylindrical cavity from the gap between the lifting rod and the cylindrical cavity. After the floating ice gathers in the space area of ​​the cylindrical cavity, the lifting rod of the diving equipment will not be able to be recovered, and even the lower end of the diving equipment will be exposed outside the second layer of the bottom of the ship. In this case, the diving equipment is very likely to collide with floating ice and be damaged during subsequent voyages, or when docking at the dock, the icebreaker cannot dock normally due to water depth restrictions.

[0004] Therefore, it is urgent to invent an auxiliary equipment for the retrieval and deployment of the underwater exploration equipment of the icebreaker and a method for using the equipment to solve the above-mentioned technical problems. Summary of the invention

[0005] The present invention provides auxiliary equipment for the deployment and retrieval of a diving device on the bottom of an icebreaker and a method for using the equipment, so as to solve the problem that large pieces of floating ice and fine pieces of floating ice affect the safety of the equipment during the exploration and recovery of the diving device, and even cause the equipment to be unable to be recovered normally, thereby ensuring the safe use of the diving device and ensuring that the lifting rod is recovered in place without affecting subsequent icebreaking navigation and berthing.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A retractable auxiliary device for a bottom-reaching device of an icebreaker, comprising an air-water connection deicing module, an ice-blocking gate module, a lifting rod, a bottom-reaching device, an upper cylindrical cavity, and a lower cylindrical cavity; the upper cylindrical cavity, the lower cylindrical cavity, the ice-blocking gate module, and the air-water connection deicing module are arranged in sequence from top to bottom; the upper cylindrical cavity and the lower cylindrical cavity have the same radial dimensions, and the two together form a channel for the bottom-reaching device to be lowered and recovered; the air-water connection deicing module has an annular shell with a hollow annular inner cavity formed therein, and a compressed air channel, an ice-free seawater channel, and an air-water outlet of the module are arranged on the air-water connection deicing module; The annular inner cavity of the air-water connection deicing module is connected with the compressed air channel and the ice-free seawater channel. The compressed air channel is used to introduce compressed air into the annular inner cavity of the air-water connection deicing module, and the ice-free seawater channel is used to introduce ice-free seawater into the annular inner cavity of the air-water connection deicing module; multiple module air-water outlets are used for compressed air or ice-free seawater in the annular inner cavity to flow out to the lower cylindrical cavity; the ice-blocking gate module includes a gate module shell and a gate tongue; the gate tongue is arranged in the gate module shell, and the gate tongue can reciprocate in the gate module shell, thereby opening and closing the downward exploration and recovery channels formed by the upper cylindrical cavity and the lower cylindrical cavity.

[0008] Furthermore, the ice-blocking gate module and the air-water connection deicing module are arranged at positions substantially consistent with the sea level or higher than the sea level.

[0009] Furthermore, the radial dimensions of the air-water connection deicing module correspond to the radial dimensions of the upper cylindrical cavity and the lower cylindrical cavity, and the inner circle dimensions of the air-water connection deicing module can ensure smooth passage of the downward-probing equipment.

[0010] Furthermore, the ice-blocking gate module also includes a transmission screw; the transmission screw is arranged on one side of the gate tongue body, and the gate tongue body is driven to reciprocate in the gate module housing through the rotation of the transmission screw.

[0011] Furthermore, the ice-blocking gate module also includes a movable ice-blocking rod and a rotating shaft; a movable ice-blocking rod storage groove is arranged on the gate tongue, and the movable ice-blocking rod is arranged in the movable ice-blocking rod storage groove through the rotating shaft.

[0012] Furthermore, in the process of the gate tongue entering the downward exploration and recovery channel formed by the upper cylindrical cavity and the lower cylindrical cavity to perform a closing action, the movable ice-blocking rod rotates downward along the rotating shaft under the action of gravity, thereby finally forming a state in which the movable ice-blocking rod extends obliquely downward into the lower cylindrical cavity; in the process of the gate tongue retracting into the gate module shell to realize the downward exploration and recovery channel formed by the upper cylindrical cavity and the lower cylindrical cavity to perform an opening action, due to the constraint of the gate module shell, the movable ice-blocking rod rotates upward along the rotating shaft and is recovered into the movable ice-blocking rod storage groove.

[0013] Furthermore, the movable ice-blocking rod is driven by a driving device to rotate along the rotating shaft; in the process of the gate tongue body entering the downward exploration and recovery channel formed by the upper cylindrical cavity and the lower cylindrical cavity to perform a closing action, the driving device drives the movable ice-blocking rod to rotate downward along the rotating shaft, thereby finally forming a state in which the movable ice-blocking rod extends obliquely downward into the lower cylindrical cavity; in the process of the gate tongue body retracting into the gate module shell to realize the downward exploration and recovery channel formed by the upper cylindrical cavity and the lower cylindrical cavity to perform an opening action, the driving device drives the movable ice-blocking rod to rotate upward along the rotating shaft and be recovered into the movable ice-blocking rod storage groove.

[0014] Furthermore, multiple module air-water outlets are evenly arranged on the annular shell of the air-water connection deicing module.

[0015] A method for using auxiliary equipment for retracting and deploying underwater exploration equipment on an icebreaker, comprising the following steps:

[0016] Step 1: After the icebreaker arrives at the scheduled operating waters, the propeller of the icebreaker reverses to create a water flow to blow away the large floating ice on the bottom of the ship;

[0017] Step 2: Compressed air is introduced into the compressed air channel on the air-water connection de-icing module, and the compressed air enters the lower cylindrical cavity from the air-water outlet of the module, with the gas at the top and the liquid at the bottom. Under the action of the air pressure, the ice-containing seawater in the lower cylindrical cavity overflows from the bottom opening of the lower cylindrical cavity, and the broken floating ice overflows from the bottom of the lower cylindrical cavity along with the water flow;

[0018] Step 3: The ice-free seawater channel is filled with ice-free seawater to prevent the gas in the lower cylindrical cavity from escaping and the seawater mixed with floating ice from surging back again;

[0019] Step 4: Open the ice-blocking gate module: the transmission screw rotates, and the gate tongue retracts in the gate module housing;

[0020] Step 5: The lifting rod moves downward, and the downward-reaching equipment passes through the ice-blocking gate module, the air-water connection deicing module, and the lower cylindrical cavity from the upper cylindrical cavity in sequence, and moves downward to the bottom of the ship;

[0021] Step 6: The downward-probing device starts the detection work until the detection work is completed;

[0022] Step 7: Compressed air is introduced into the compressed air channel, and the compressed air enters the lower cylindrical cavity from the air and water outlet of the module, with the gas at the top and the liquid at the bottom. Under the action of the air pressure, the seawater in the lower cylindrical cavity overflows from the bottom opening of the lower cylindrical cavity. During the operation of the down-going device, the broken floating ice that enters the lower cylindrical cavity with the water flow overflows from the bottom of the lower cylindrical cavity with the seawater.

[0023] Step 8: The ice-free seawater channel is filled with ice-free seawater to prevent the gas in the lower cylindrical cavity from escaping and the seawater mixed with floating ice from surging back again;

[0024] Step 9: Retract the lifting rod and the downward-reaching equipment;

[0025] Step 10: The lifting rod is retracted into place, and the downward-reaching device is completely returned to the upper cylindrical cavity;

[0026] Step 11: Close the ice-blocking gate module: the transmission screw rotates in the opposite direction, and the gate tongue extends from the gate module housing.

[0027] Further, in step 4, during the process of the gate tongue retracting in the gate module housing, the movable ice-blocking rod rotates along the rotating shaft and returns to the movable ice-blocking rod storage groove; in step 11, during the process of the gate tongue extending from the gate module housing, the movable ice-blocking rod rotates downward along the rotating shaft and rotates out of the movable ice-blocking rod storage groove; until the ice-blocking gate module is completely closed, the movable ice-blocking rod forms a blocking mode in the lower cylindrical cavity to prevent large pieces of floating ice from entering the lower cylindrical cavity.

[0028] Compared with the prior art, the present invention has the following advantages and technical effects:

[0029] (1) The auxiliary equipment for deploying and retracting the diving equipment under the icebreaker of the present invention has an air-water connection de-icing module, which can effectively prevent the equipment from being damaged by the broken floating ice in the cylindrical cavity during the diving process of the diving equipment; at the same time, when the diving equipment is recovered, it can prevent the floating ice from entering the cylindrical cavity from the gap between the lifting rod and the cylindrical cavity, ensuring that the lifting rod is recovered in place without affecting the subsequent icebreaking navigation and berthing.

Example

[0061] Figure 1 The overall structure diagram of the present invention is a schematic diagram of the auxiliary equipment for retracting and deploying the under-the-bottom exploration equipment of an icebreaker. Figure 1 As shown, the retractable auxiliary equipment 100 of the present invention mainly includes an air-water connection deicing module 10, an ice-blocking gate module 20, a lifting rod 30, a downward-exploring device 40, an upper cylindrical cavity 50, and a lower cylindrical cavity 51. The upper cylindrical cavity 50, the lower cylindrical cavity 51, the ice-blocking gate module 20, and the air-water connection deicing module 10 are arranged in sequence from top to bottom, and the ice-blocking gate module 20 and the air-water connection deicing module 10 are located between the upper cylindrical cavity 50 and the lower cylindrical cavity 51. The ice-blocking gate module 20 and the air-water connection deicing module 10 are arranged at positions substantially consistent with the sea level, or above the sea level. The upper cylindrical cavity 50 and the lower cylindrical cavity 51 have the same radial dimensions, and the two together form a channel for the downward-exploring device 40 to explore and recover.

[0062] like Figure 4 and 5 As shown, the air-water connection deicing module 10 has an annular shell with a hollow annular inner cavity formed inside. Its radial dimensions correspond to the radial dimensions of the upper cylindrical cavity 50 and the lower cylindrical cavity 51, and the inner circle dimensions of the air-water connection deicing module 10 can ensure the smooth passage of the downward-probing equipment 40.

[0063] The air-water connection deicing module 10 is provided with: a compressed air channel 11, an ice-free seawater channel 12, and a plurality of module air-water outlets 13. The annular inner cavity of the air-water connection deicing module 10 is connected with the compressed air channel 11 and the ice-free seawater channel 12. The compressed air channel 11 is used to introduce compressed air into the annular inner cavity of the air-water connection deicing module 10, and the ice-free seawater channel 12 is used to introduce ice-free seawater into the annular inner cavity of the air-water connection deicing module 10. The plurality of module air-water outlets 13 are evenly arranged on the annular shell of the air-water connection deicing module 10, and are used for the compressed air or ice-free seawater in the annular inner cavity to evenly flow out to the lower cylindrical cavity 51.

[0064] like Figure 6As shown, the ice-blocking gate module 20 includes: a gate module housing 21, a gate tongue 22, a movable ice-blocking rod 23, a rotating shaft 24, and a transmission screw 25. The gate tongue 22 is arranged in the gate module housing 21, and a transmission screw 25 is arranged on one side of the gate tongue 22. The gate tongue 22 can be driven to reciprocate in the gate module housing 21 by the rotation of the transmission screw 25, so as to open and close the downward exploration and recovery channel formed by the upper cylindrical cavity 50 and the lower cylindrical cavity 51. The gate tongue 22 is provided with a movable ice-blocking rod storage groove 26, and the movable ice-blocking rod 23 is arranged in the movable ice-blocking rod storage groove 26 through the rotating shaft 24.

[0065] Preferably, in the process of the gate tongue 22 entering the downward exploration and recovery channel formed by the upper cylindrical cavity 50 and the lower cylindrical cavity 51 to perform the closing action, the movable ice-blocking rod 23 can rotate downward along the rotating shaft 24 under the action of gravity, so as to finally form a state in which the movable ice-blocking rod 23 extends obliquely downward into the lower cylindrical cavity 51. Since the movable ice-blocking rod 23 extends obliquely downward into the lower cylindrical cavity 51, large pieces of floating ice can be prevented from entering the lower cylindrical cavity 51 during the navigation of the icebreaker. In the process of the gate tongue 22 retracting into the gate module housing 21 to realize the downward exploration and recovery channel formed by the upper cylindrical cavity 50 and the lower cylindrical cavity 51 to perform the opening action, due to the constraint of the gate module housing 21, the movable ice-blocking rod 23 can be rotated upward along the rotating shaft 24 and recovered into the movable ice-blocking rod storage groove 26.

[0066] Furthermore, the movable ice-blocking rod 23 can also be driven by a driving device to rotate along the rotating shaft 24. In the process of the gate tongue 22 entering the downward exploration and recovery channel formed by the upper cylindrical cavity 50 and the lower cylindrical cavity 51 to perform a closing action, the driving device drives the movable ice-blocking rod 23 to rotate downward along the rotating shaft 24, thereby finally forming a state in which the movable ice-blocking rod 23 extends obliquely downward into the lower cylindrical cavity 51. Since the movable ice-blocking rod 23 extends obliquely downward into the lower cylindrical cavity 51, large pieces of floating ice can be prevented from entering the lower cylindrical cavity 51 during the navigation of the icebreaker. In the process of the gate tongue 22 retracting into the gate module housing 21 to realize the downward exploration and recovery channel formed by the upper cylindrical cavity 50 and the lower cylindrical cavity 51 to perform an opening action, the driving device drives the movable ice-blocking rod 23 to rotate upward along the rotating shaft 24 and be recovered into the movable ice-blocking rod storage groove 26. Example

[0067] The present invention provides a method for using auxiliary equipment for retracting and deploying under-the-bottom exploration equipment of an icebreaker, which specifically comprises the following steps:

[0068] Step 1: After the icebreaker arrives at the scheduled operating waters, the propeller of the icebreaker reverses to create a water flow to blow away the large floating ice on the bottom of the ship;

[0069] Step 2: Compressed air is introduced into the compressed air channel 11 on the air-water connection de-icing module 10, and the compressed air enters the lower cylindrical cavity 51 from the module air-water outlet 13, with the gas at the top and the liquid at the bottom. Under the action of the air pressure, the ice-containing seawater in the lower cylindrical cavity 51 overflows from the bottom opening of the lower cylindrical cavity 51, and the broken floating ice overflows from the bottom of the lower cylindrical cavity 51 along with the water flow;

[0070] Step 3: ice-free seawater is introduced into the ice-free seawater channel 12 to prevent the seawater mixed with floating ice from flowing back again after the gas in the lower cylindrical cavity 51 escapes;

[0071] Step 4: Open the ice-blocking gate module 20: The transmission screw 25 rotates, and the gate tongue 22 retracts in the gate module housing 21; during this process, the movable ice-blocking rod 23 is constrained by the gate module housing 21, and moves along the rotating shaft 24 and returns to the movable ice-blocking rod storage groove 26;

[0072] Step 5: The lifting rod 30 moves downward, and the downward-moving device 40 passes through the ice-blocking gate module 20, the air-water connection deicing module 10, and the lower cylindrical cavity 51 from the upper cylindrical cavity 50 in sequence, and moves downward to the bottom of the ship;

[0073] Step 6: The downward probe device 40 starts the detection work until the detection work is completed;

[0074] Step 7: Compressed air is introduced into the compressed air channel 11, and the compressed air enters the lower cylindrical cavity 51 from the module air-water outlet 13, with the gas at the top and the liquid at the bottom. Under the action of the air pressure, the seawater in the lower cylindrical cavity 51 overflows from the bottom opening of the lower cylindrical cavity 51, and during the operation of the down-going device 40, the broken floating ice entering the lower cylindrical cavity 51 with the water flow overflows from the bottom of the lower cylindrical cavity 51 with the seawater;

[0075] Step 8: The ice-free seawater channel 12 is fed with ice-free seawater to prevent the seawater mixed with floating ice from flowing back again after the gas in the lower cylindrical cavity 51 escapes;

[0076] Step 9: Recover the lifting rod 30, and the downward-reaching device 40 is also recovered;

[0077] Step 10: The lifting rod 30 is recovered and the downward-probing device 40 is completely returned to the upper cylindrical cavity 50;

[0078] Step 11: Close the ice-blocking gate module 20: The transmission screw 25 rotates in the opposite direction, and the gate tongue 22 extends from the gate module housing 21; during this process, the movable ice-blocking rod 23 disengages from the movable ice-blocking rod storage groove 26, leaves the constraint of the gate module housing 21, and falls along the rotating shaft 24; until the ice-blocking gate module 20 is completely closed, the movable ice-blocking rod 23 forms a supporting mode in the lower cylindrical cavity 51 to prevent large pieces of floating ice from entering the lower cylindrical cavity 51.

[0079] Further, in step 4 , during the process of the gate tongue 22 retracting in the gate module housing 21 , the movable ice-blocking rod 23 rotates along the rotating shaft 24 and returns to the movable ice-blocking rod storage groove 26 .

[0080] Further, in step 11, while the gate tongue 22 is extending from the gate module housing 21, the movable ice-blocking rod 23 rotates downward along the rotating shaft 24 and rotates out from the movable ice-blocking rod storage groove 26; until the ice-blocking gate module 20 is completely closed, the movable ice-blocking rod 23 forms a blocking mode in the lower cylindrical cavity 51 to prevent large pieces of floating ice from entering the lower cylindrical cavity 51.

[0081] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.

8. The auxiliary equipment for retracting and deploying the under-the-ship exploration equipment of an icebreaker according to claim 1, characterized in that: A plurality of module air-water outlets (13) are evenly arranged on the annular shell of the air-water connection deicing module (10).

9. A method for using the auxiliary equipment for deploying and retracting under-the-bottom exploration equipment of an icebreaker according to any one of claims 1 to 6, characterized in that: The method specifically comprises the following steps: step 1: after the icebreaker arrives at the predetermined operating waters, the propeller of the icebreaker is reversed to create a water flow to blow away the large floating ice on the bottom of the ship; step 2: compressed air is introduced into the compressed air channel (11) on the air-water connection de-icing module (10), and the compressed air enters the lower cylindrical cavity (51) from the module air-water outlet (13), with the gas at the top and the liquid at the bottom. Under the action of the air pressure, the ice-containing seawater in the lower cylindrical cavity (51) overflows from the bottom opening of the lower cylindrical cavity (51), and the fine floating ice is blown out from the lower cylindrical cavity (51) along with the water flow. The bottom of the cavity (51) overflows; step 3: the ice-free seawater channel (12) is introduced into the ice-free seawater channel to prevent the seawater mixed with floating ice from flowing back again after the gas in the lower cylindrical cavity (51) also escapes; step 4: opening the ice-blocking gate module (20): the transmission screw (25) rotates, and the gate tongue (22) retracts in the gate module housing (21); step 5: the lifting rod (30) moves downward, and the downward-probing device (40) then passes through the ice-blocking gate module (20), the air-water connection deicing module (10), the lower cylindrical cavity ( 51), and probe to the bottom of the ship; step 6: the probe device (40) starts the detection work until the detection work is completed; step 7: compressed air is introduced into the compressed air channel (11), and the compressed air enters the lower cylindrical cavity (51) from the module air and water outlet (13), with the gas at the top and the liquid at the bottom. Under the action of the air pressure, the seawater in the lower cylindrical cavity (51) overflows from the bottom opening of the lower cylindrical cavity (51), and the fine floating ice that enters the lower cylindrical cavity (51) with the water flow is discharged from the lower cylindrical cavity (51) along with the seawater during the operation of the probe device (40). The bottom of the cavity (51) overflows; step 8: the ice-free seawater channel (12) is introduced with ice-free seawater to prevent the gas in the lower cylindrical cavity (51) from escaping and the seawater mixed with floating ice from flowing back again; step 9: the lifting rod (30) is recovered, and the downward-exploring device (40) is also recovered; step 10: the lifting rod (30) is recovered in place, and the downward-exploring device (40) is completely returned to the upper cylindrical cavity (50); step 11: closing the ice-blocking gate module (20): the transmission screw (25) rotates in the opposite direction, and the gate tongue (22) extends out of the gate module housing (21).
