Description

Technical Field

[0001] The present invention relates to the technical field of shipwreck salvage engineering, and in particular to an expandable electromagnetic heating device for heating heavy oil in a shipwreck and a method of using the device. Background Art

[0002] The principle of electromagnetic induction heating is that the alternating current generated by the induction heating power supply passes through the inductor (i.e., coil) to generate an alternating magnetic field. A magnetic object placed in this field cuts the alternating magnetic lines of force, thereby generating alternating currents (i.e., eddy currents) within the object. The eddy currents cause the atoms inside the object to move at high speed and irregularly. The atoms collide and rub against each other, generating heat energy, which in turn heats the object. In other words, this is a heating method that converts electrical energy into magnetic energy, causing the heated steel object to sense the magnetic energy and generate heat.

[0003] After a ship sinks in a marine accident, fuel recovery is necessary to prevent secondary pollution of the marine environment. In winter, or when the heavy oil from a shipwreck is underwater at depths exceeding 80m, it becomes non-fluid. Therefore, the initial recovery phase requires heating the oil within the shipwreck's fuel tanks. Currently, steam heating is the most common heating method used both domestically and internationally. This involves installing multiple heating pipes in series within the tanks to heat the heavy oil at multiple points. The steam circulates within the pipes and returns to the heating boiler as warm water, or the steam is sprayed directly into the shipwreck's fuel tanks through steam lines. While existing technologies can heat and soften non-fluid heavy oil in these challenging environments, steam boilers are bulky, heavy, and require high maintenance. Furthermore, their heating pipes are subject to limitations such as depth limitations, high heat loss, difficulty for divers connecting the pipes underwater, and low heating efficiency. Summary of the Invention

[0004] In response to the above technical problems, an expandable electromagnetic heating device for heating heavy oil in a sunken ship and a method of using the same are provided.

[0005] The technical means adopted in the present invention are as follows:

[0006] An expandable electromagnetic heating device for heating heavy oil in a shipwreck comprises several steel heating chambers, a handle, a guide mechanism and a moving mechanism. The steel heating chambers are equipped with high-temperature resistant and waterproof insulated electric coils and temperature sensors. The steel heating chambers can be combined to form a complete tubular structure. The output end of the handle is connected to the guide mechanism, and the moving mechanism is connected to each steel heating chamber. The moving mechanism is arranged on the guide mechanism. Based on the rotation of the handle, the angle between each steel heating chamber is adjusted. The guide mechanism is provided with a connecting mechanism for connecting to the shipwreck interface of the heavy oil to be heated.

[0007] Furthermore, the number of the steel heating chambers is at least 3.

[0008] Furthermore, the middle and lower parts of the inner wall of the steel heating chamber are hinged to a connecting rod respectively, the top of the steel heating chamber is hinged to the transition connecting pipe, a flange is welded in the middle of the connecting pipe, and a screw rod is installed inside the connecting pipe passing through it. The screw rod can rotate in the connecting pipe and the top end of the screw rod extends upward and is fixedly installed with the handle. A nut is installed in the middle of the screw rod, and the nut is hinged to the connecting rod.

[0009] Furthermore, the lower 2 / 3 of the three steel heating chambers are connected to the nuts on the screw rods through connecting rods.

[0010] Furthermore, the connection terminal of the high-temperature resistant and waterproof insulated electric coil passes through a connecting pipe and reaches the surface construction vessel and is connected to the electromagnetic generator.

[0011] Furthermore, the connection terminal of the temperature sensor passes through the connecting pipe and reaches the surface construction ship to be connected to the temperature sensor display screen.

[0012] Furthermore, the connecting mechanism includes a flange welded in the middle of the connecting pipe, and the electromagnetic heating device is fixed to the outer plate of the oil tank of the sunken ship through the flange.

[0013] The present invention also provides a method for using an expandable electromagnetic heating device for heating heavy oil in a sunken ship, comprising the following steps:

[0014] S1: A penetration hole is opened on the steel plate of the heavy oil tank of the sunken ship, and the bottom of the expandable electromagnetic heating device for heating the heavy oil of the sunken ship is inserted into the heavy oil tank of the sunken ship through the penetration hole, and the flange is fixedly connected to the heavy oil tank of the sunken ship by bolts;

[0015] S2: The terminal of the high-temperature resistant and waterproof insulated electric coil and the terminal of the temperature sensor are connected to the electromagnetic generator and the temperature sensor display screen on the surface operation ship respectively;

[0016] S3: activating the electromagnetic generator, the high-temperature resistant and waterproof insulated electric coil generates a high-speed changing alternating magnetic field, and under the action of the magnetic field, the steel heating chamber generates heat, thereby heating the heavy oil in the heavy oil tank of the sunken ship;

[0017] S4: Turn the handle to heat and soften the heavy oil, and control the opening and closing of the heating chamber through the transmission sequence of handle-screw-nut-connecting rod-heating chamber, so that the heating chamber fits the unheated heavy oil.

[0018] Furthermore, in the step S3, during the heating process, the temperature sensor measures the heating temperature in real time, and stops the electromagnetic generator when the temperature exceeds 200°C.

[0019] Compared to existing technologies, this invention offers the following advantages: This expandable electromagnetic heating device for heating heavy oil from sunken ships aims to change traditional heating methods. By combining electromagnetic heating tubes to heat softened heavy oil, the expandable heating chamber increases the heating range, improving the efficiency of the heavy oil recovery and heating process. Its compact size and light weight facilitate underwater installation by divers and portability into the engine room, improving underwater installation and operational efficiency compared to traditional steam heating methods.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0032] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values ​​described in these embodiments do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0033] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

[0036] like Figures 1 to 7 As shown, an embodiment of the present invention discloses an expandable electromagnetic heating device for heating heavy oil in a shipwreck, comprising a plurality of steel heating chambers 2, a handle 7, a guide mechanism and a moving mechanism. The steel heating chambers are equipped with high-temperature resistant and waterproof insulated electric coils 8 and temperature sensors 9. The steel heating chambers can be combined to form a complete tubular structure. The output end of the handle is connected to the guide mechanism, and the moving mechanism is connected to each steel heating chamber. The moving mechanism is arranged on the guide mechanism, and the angle between each steel heating chamber is adjusted based on the rotation of the handle. A connecting mechanism is provided on the guide mechanism for connecting to the shipwreck interface of the heavy oil to be heated.

[0037] Furthermore, the number of the steel heating chambers is at least 3.

[0038] As an optional embodiment, the guide mechanism and the moving mechanism are specifically composed as follows: the middle and lower portions of the inner wall of the steel heating chamber are respectively hinged to a connecting rod 3 via a hinged lug 2.2 in the middle of the heating chamber. The top of the steel heating chamber is hinged to a transition connecting pipe 6 via a hinged lug 2.1 at the top of the heating chamber and a hinged lug 6.1 on the connecting pipe. A flange 1 is welded to the middle of the connecting pipe. A screw 5 is installed inside the connecting pipe and passes through it. The screw can rotate within the connecting pipe, and the top of the screw extends upward and is fixedly mounted with the handle. A nut 4 is installed in the middle of the screw, and the nut is hinged to the connecting rod via a nut hinged lug 4.1. When the handle is rotated to drive the screw, the nut moves axially along the screw, controlling the opening or closing of the heating chamber through the connecting rod.

[0039] Furthermore, the lower 2 / 3 of the three steel heating chambers are connected to the nuts on the screw rods through connecting rods.

[0040] Furthermore, the connection terminal of the high-temperature resistant and waterproof insulated electric coil passes through the insulating wire 11 through the connecting pipe and reaches the surface construction ship and is connected to the electromagnetic generator.

[0041] Furthermore, the connection terminal of the temperature sensor passes through the connecting pipe and reaches the surface construction ship through the temperature sensor line 10 to be connected to the temperature sensor display screen.

[0042] The above-mentioned circuit is wound on a high-temperature resistant plastic winding support plate 12.

[0043] Furthermore, the connection mechanism includes a flange welded to the middle of the connecting pipe, which secures the electromagnetic heating device to the outer plating of the sunken ship's oil tank. A rubber ring is installed in the opening at the upper end of the flange, through which the terminals of the high-temperature, waterproof, insulated coil and the temperature sensor are inserted into the steel heating chamber.

[0044] The present invention also provides a method for using an expandable electromagnetic heating device for heating heavy oil in a sunken ship, comprising the following steps:

[0045] S1: A penetration hole is opened on the steel plate of the heavy oil tank of the sunken ship, and the bottom of the expandable electromagnetic heating device for heating the heavy oil of the sunken ship is inserted into the heavy oil tank of the sunken ship through the penetration hole, and the flange is fixedly connected to the heavy oil tank of the sunken ship by bolts;

[0046] S2: The terminal of the high-temperature resistant and waterproof insulated electric coil and the terminal of the temperature sensor are connected to the electromagnetic generator and the temperature sensor display screen on the surface operation ship respectively;

[0047] S3: activating the electromagnetic generator, the high-temperature resistant and waterproof insulated electric coil generates a high-speed changing alternating magnetic field, and under the action of the magnetic field, the steel heating chamber generates heat, thereby heating the heavy oil in the heavy oil tank of the sunken ship;

[0048] S4: Turn the handle to heat and soften the heavy oil, and control the opening and closing of the heating chamber through the transmission sequence of handle-screw-nut-connecting rod-heating chamber, so that the heating chamber fits the unheated heavy oil.

[0049] Furthermore, in the step S3, during the heating process, the temperature sensor measures the heating temperature in real time, and stops the electromagnetic generator when the temperature exceeds 200°C.

[0050] This invention uses electromagnetic heating to heat low-temperature heavy oil within a sunken ship. The heating chamber can be opened and closed with a handle, effectively increasing the contact area between the heating chamber and the heavy oil, creating a single-point, multi-point heating operation. This improves the efficiency of heating the low-temperature heavy oil within the shipwreck, thereby enhancing the efficiency of heavy oil recovery operations within the shipwreck. Its small size and light weight make it easy for divers to install underwater, and it improves the efficiency of underwater heavy oil heating operations compared to traditional single-point heating rods.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
