Abstract
Description
Technical Field
[0001] This invention relates to the field of electric heater technology, specifically to electric heaters for large cruise ships. Background Technology
[0002] The batteries in the battery room and the crankshaft in the bow thruster of large cruise ships have high temperature requirements because low winter temperatures can cause battery failure and crankshaft deformation. In addition, since the battery room and the bow thruster are large in volume and are only used under specific conditions, providing air conditioning heating to the two cabins would waste a lot of energy. Therefore, in order to reduce the number of outfitting components such as air ducts and energy consumption, a certain number of marine electric heaters are installed in the two cabins to ensure the normal operation of the equipment in the cabins when the ambient temperature is too low.
[0003] Electric heaters installed in large cruise ship cabins generally need to be removed when the ambient temperature rises. Furthermore, the heaters operate at consistently high temperatures, making their wiring prone to aging and requiring frequent shutdowns and replacements. However, current technology suffers from small air outlets in electric heaters, requiring a considerable amount of time to raise the cabin temperature. This prolonged heating time is particularly problematic in large battery storage areas with numerous devices. After shutdown and maintenance, rapid heating is not achieved, impacting the normal operation of the battery storage areas. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] Please see Figure 1-11 A large cruise ship electric heater includes: a base frame 1, a side support 2 on the side of the base frame 1, a pushing mechanism 3 installed on the side of the side support 2 away from the base frame 1, a support frame 4 installed on the top of the base frame 1, the support frame 4 having a frame structure, a first heater body 6 placed inside the support frame 4, a second heater body 7 hinged to the top of the first heater body 6, a transfer bracket 8 installed inside the base frame 1, a shaft 10 rotatably mounted at the bottom of the transfer bracket 8, worm gears 12 fixedly sleeved on the surfaces of the shaft 10 near both ends, a lead screw 9 rotatably connected to the top of the base frame 1, the top of the lead screw 9 rotatably connected to the support frame 4, the bottom of the lead screw 9 penetrating the base frame 1 and fixedly sleeved with a worm wheel 11, the outer edge of the worm wheel 11 meshing with the worm gear 12, one end of the shaft 10 penetrating the side support 2 and mounted with a hand control panel 13, a lifting platform 14 threadedly connected to the surface of the lead screw 9, the lifting platform 14 overlapping the bottom of the first heater body 6, and a sliding sleeve mechanism 5 slidably sleeved on the surface of the support frame 4.
[0032] The first heater body 6 and the second heater body 7 are both single-sided open box-shaped structures. The open surfaces of the first heater body 6 and the second heater body 7 are hinged. Junction boxes 16 are installed on the sides of both the first heater body 6 and the second heater body 7. The two junction boxes 16 are connected by wires, such as... Figure 6 As shown, during use, the first heater body 6 and the second heater body 7 can be flipped and straightened by using the hinge, which can fully expose the open surface, thereby maximizing the heating surface of the electric heater and rapidly raising the temperature inside the cabin.
[0033] In this design, heating tubes 17 are installed inside both the first heater body 6 and the second heater body 7 via junction boxes 16. Guardrails 18 are installed on the inner walls of the first heater body 6 and the second heater body 7 near their open surfaces. Baffles 19 are installed on the inner walls of the first heater body 6 and the second heater body 7. The baffles 19 are located behind the heating tubes 17 and have several through holes on their surface. By setting up guardrails 18 to block the heating tubes 17 inside the first heater body 6 and the second heater body 7, the operators are protected from accidental burns. Furthermore, the baffles 19 separate the interiors of the first heater body 6 and the second heater body 7, allowing the air entering them to be diverted by the baffles 19, increasing the heat dissipation surface, and thus improving the heating effect.
[0034] The first heater body 6 has a fan 20 mounted on its back. Ventilation openings are provided at the top of the first heater body 6 and the ends of the second heater body 7, and the positions of the ventilation openings on the surfaces of the first heater body 6 and the second heater body 7 correspond to each other. Figure 7 As shown, the baffle 19 is used to block the wind blown in by the fan 20 within a certain range, so that the wind force is diverted, and the diverted wind can enter the second heater body 7 through the vent, thereby increasing the blowing area.
[0035] The second heater body 7 has a positioning hook 21 installed on its back, and the top of the support frame 4 has a positioning groove 15. The size of the positioning groove 15 and the inner wall of the second heater body 7 are both adapted to the diameter of the U-shaped frame rotatably mounted on the surface of the sliding sleeve mechanism 5, and their positions correspond to the sliding of the sliding sleeve mechanism 5. Figure 1 and Figure 8 As shown, the fixed position of the sliding sleeve mechanism 5 varies depending on the state of the electric heater during its movement and heating. The sliding sleeve mechanism 5 can be adjusted according to the different states of the electric heater, so that the electric heater can be stably placed on the base frame 1.
[0036] The pushing mechanism 3 includes a guide block 31, with a limiting groove 32 at its bottom. A support rod 34 is slidably mounted on the inner wall of the limiting groove 32, and a roller 36 is rotatably mounted on the bottom of the support rod 34. There are four pushing mechanisms 3. The roller 36 between two pushing mechanisms 3 located at the same end of the base frame 1 has a single integral round rod as its pivot. Figure 1 and Figure 8 As shown, depending on the different usage requirements of the electric heater, simply lift one end of the base frame 1 and use the foot pedal to push the linkage rod of the moving mechanism 3 to automatically switch between the support state and the moving state.
[0037] Among them, the surface of the guide block 31 is provided with a guide groove 33, and the inner wall of the guide groove 33 is slidably connected with a guide rod 39. The guide rod 39 is integrally set on the surface of the support rod 34 near the top. The inner wall of the limiting groove 32 near the bottom is provided with a notch. The surface of the support rod 34 overlaps with the inner wall of the notch of the limiting groove 32. The guide groove 33 is used to restrict the movement of the support rod 34, so that one end is always located inside the limiting groove 32.
[0038] Among them, a first round shaft 35 is provided on one end of the roller 36 rotating shaft, and a second round shaft 37 is installed on the surface of the guide block 31 near the top. A tension spring 38 is provided between the first round shaft 35 and the second round shaft 37. The top and bottom of the tension spring 38 are respectively equipped with components that are rotatably connected to the second round shaft 37 and the first round shaft 35. The tension of the tension spring 38 is used to maintain the endurance of the state after the push mechanism 3 is switched. At the same time, when the linkage rod of the push mechanism 3 is stepped on, the push mechanism 3 can automatically bend or automatically retract into the limiting groove 32 after the support rod 34 pops out due to the influence of the tension spring 38.
[0039] The sliding sleeve mechanism 5 includes a positioning sleeve 51, a railing 52 rotatably mounted on the side of the positioning sleeve 51, an externally threaded cylinder 53 integrally mounted on the bottom of the positioning sleeve 51, a groove 54 formed at the bottom of the externally threaded cylinder 53, a brake block 55 rotatably mounted inside the groove 54, and a pressure-receiving cylinder 56 threadedly fitted onto the surface of the externally threaded cylinder 53. Figure 10 and Figure 11 As shown, after the electric heater is stabilized by the railing 52, the sliding sleeve mechanism 5 can be automatically fixed on the support frame 4 to prevent the railing 52 from falling off, thereby further improving the stability of the electric heater.
[0040] Among them, the bottom of the brake block 55 is wedge-shaped, one side of the brake block 55 is in contact with the surface of the frame column of the handrail 4, the inside of the pressure cylinder 56 near the bottom is funnel-shaped, and the inclination angle of the funnel-shaped inner wall of the pressure cylinder 56 corresponds to the slope of the surface of the brake block 55. When the pressure cylinder 56 is turned, the upward force of the pressure cylinder 56 is used to compress the distance between the brake block 55 and the frame column of the handrail 4, thereby achieving the effect of fixing the position of the sliding sleeve mechanism 5.
[0041] Working principle: When using electric heaters to heat the cabins of large cruise ships, first push the electric heater into the predetermined position in the cabin, then lift one end of the base frame 1 and use the foot pedal to push the linkage rod of the moving mechanism 3 to automatically switch its support state. Then, loosen the fixing of the sliding sleeve mechanism 5, flip the second heater body 7 upward, and then rotate the hand control panel 13 to use the lifting platform 14 to drive the first heater body 6 and the second heater body 7 to lower their height. Then, slide the sliding sleeve mechanism 5 and hang it in the positioning groove 15 and tighten it to block the lower middle position of the second heater body 7, thereby achieving a stabilizing effect. Finally, connect the circuit, start the fan 20, and the air blown into the first heater body 6 and the second heater body 7 is diverted by the partition 19 to increase the heat dissipation area. When the electric heater needs to be repaired, simply fold the electric heater and the base frame 1 into the original position suitable for pushing by following the reverse steps above.
[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
