Description

Technical Field

[0001] The utility model relates to the field of ship auxiliary equipment, in particular to a releaser for preventing freezing and related equipment. Background Art

[0002] Life rafts are life-saving equipment equipped on ships for emergency escape. Most of them are fixed to the ship through a life raft release device. When an emergency occurs, the life raft release device will operate to release the ship's fixation on the life raft, allowing the life raft to fall into the water for escape. The existing life raft release device can use hydrostatic pressure to automatically release the fixation of the life raft when the ship sinks and wades. Since ships are very likely to encounter extreme climates when sailing on sea routes, such as heavy snow, storms, etc., and the temperature is extremely low when sailing near the Arctic and Antarctic regions, the life raft release devices on the market do not have the function of ensuring that they continue to work in the polar regions. When ropes or cables are easily frozen in low temperature environments, it will affect the normal operation of the life raft release device. Therefore, a releaser is needed in the market to ensure that the release of the life valve will not be affected in the polar regions.

[0003] After investigation, the patent number CN202321605547.5 discloses a hydrostatic pressure release device, including a first connecting rope, a pressure releaser, a release hook, a second connecting rope, a head-throwing rope, a breakable ring and a raft frame for fixing a life raft, the pressure releaser is provided with a second connecting rope, and a blade is provided in the pressure releaser near the second connecting rope to cut off the second connecting rope when subjected to a certain pressure, the release hook is provided at the upper end of the pressure releaser and connected to the raft frame through the second connecting rope, one end of the first connecting rope is connected to the life raft, and the other end is connected to the release hook, one end of the head-throwing rope is connected to the inflatable component of the life raft, and the other end is connected to the raft frame through the breakable ring, and the characteristic is that the pressure releaser is provided with a pressure maintaining mechanism that can keep the gas pressure within a certain range when the gas pressure inside the pressure releaser is affected by temperature. The advantage is that the hydrostatic pressure release device can work normally when the temperature affects the pressure, that is, the life raft will not be released when the water depth does not reach a certain level, but there may be unexpected risks when working in a cold place.

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] Example 1

[0035] according to Figures 1 to 4 A release device for preventing freezing includes a box body 1, a box cover 2, and a release unit 3. The box cover 2 is fixed on the top of the box body 1, and the release unit 3 for cutting the cable 4 and the cable 5 is fixed in the box body 1. A hydrostatic pressure water inlet device 6 is fixed on the inner wall of the box body 1. The practical new type focuses on that at least part of the outer shell of the release unit 3 is made of metal material, which is used to fix the temperature-controlled electric heating element 7. In this embodiment, the power supply unit adopts a power supply processing unit 8, which processes the external power supply and supplies power to the electric heating element 7. The box body 1 is also provided with a thermostat 9 that controls whether the electric heating element 7 works or not according to the external temperature. Of course, the power supply unit can use a battery or a low-voltage power supply to directly supply power to the electric heating element 7.

[0036] The releaser unit 3 preferably uses the cover plate on the shell as the metal heat conducting plate 10, which is convenient for assembly and production. The top of the metal heat conducting plate 10 is fixed with a temperature-controlled electric heating element 7 to accurately control the temperature. The temperature-controlled electric heating element 7 includes an electric heater 13 and a high-temperature temperature control switch 14. When the temperature is detected to be too high above 30 degrees Celsius, the electric heater 13 will stop working. The high-temperature temperature control switch 14 adopts a normally closed 30-degree type switch. The thermostat 9 adopts a low-temperature temperature control switch. When the temperature outside the box 1 is too low to below 10 degrees Celsius, the thermostat 9 will control the temperature-controlled electric heating element 7 to heat up to prevent the outer wall of the cable 5 and the cable 4 from being frozen. The low-temperature temperature control switch adopts a normally open 10-degree type switch.

[0037] The power processing unit 8 includes a rectifier 15 , one end of the rectifier 15 is connected to an input wire 23 , and the other end of the rectifier 15 is used as an output end to supply power to each unit through a diode.

[0038] The releaser unit 3 includes a cable releaser unit 11 and a cable releaser unit 12. A cable 4 is fixed in the release hole of the cable releaser unit 11, and a cable 5 is fixed in the release hole of the cable releaser unit 12, so that double safety can be achieved. The releaser unit 3 is connected to a signal unit through a circuit, and cooperates with a remote controller to remotely start the release unit 3 through the remote controller. The structural principle of the releaser unit can refer to the previous patent technology of the applicant.

[0039] The hydrostatic pressure water inlet device 6 adopts a hollow metal column with an inverted T-shaped cross section, and a plurality of water inlet and outlet holes 16 are arranged on the outer wall of the metal column. The water inlet and outlet holes 16 include a water inlet hole 17 and a water outlet hole 18, and the position of the water outlet hole 18 is lower than the water inlet hole 17, so that when water enters the box body 1, the water is discharged from the water outlet hole 18 by gravity. A sponge membrane is fixed in the water inlet hole 17 to prevent rainwater from entering the box body 1, but when a large water pressure flows into the box body 1, it does not affect its water inlet, so that when the water pressure in the box body is too large, the large water pressure drives the release unit 3 to work, ensuring that the release unit 3 can also work automatically in the water. The temperature-controlled electric heating element 7 also adopts a spring-type coil 24, which is sleeved between the hollow metal column and the fixed column on the metal heat conductive plate 10, and can heat the hollow metal column and the metal heat conductive plate 1 to prevent the temperature from being too low and being frozen.

[0040] The bottom of the box body 1 is provided with a fixing groove 19, which matches the release unit 3 and realizes the function of fixing the release unit 3 on the fixing groove 19. The box cover 2 is made of transparent color, so that the user can directly observe the expiration date of the release unit 3 and the working conditions of various components in the box body 1 through the box cover 2. Nut grooves 20 are provided at the four corners of the box body 1, and corresponding fixing holes 21 are provided on the box cover 2. Screws pass through the fixing holes 21 to fix the box cover 2 to the box body 1. A sealing ring 22 is fixed between the box cover 2 and the box body 1 to prevent water seepage.

[0041] When the user needs to install and use this product, he only needs to insert the cable 4 and the cable 5 into the cable release unit 11 and the cable release unit 12 respectively, and insert the input wire 23 into the power socket to complete the preparation. When the thermostat 9 senses that the temperature outside the box 1 is lower than 10 degrees Celsius, it will control the temperature-controlled electric heating element 7 to heat up. When the high-temperature temperature control switch 14 on the metal heat-conducting plate 10 detects that the temperature is too high, the temperature-controlled electric heating element 7 stops heating to prevent the outer wall of the releaser unit 3, the cable 5 and the cable 4 from being frozen. The user can passively or actively use the remote control to start this device, so as to actively make the cable release unit 11 and the cable release unit 12 work, thereby completing the release work. When the user does not have time to actively operate the releaser and the releaser has entered the water, water will flow in from the water inlet hole 16 of the hydrostatic pressure water inlet device 6, and the releaser unit 3 will automatically cut off the cable and the cable.

[0042] Example 2

[0043] like Figure 5, which is different from Example 1, is a releaser to prevent freezing, which uses a single releaser unit 3. The releaser unit 3 preferably uses the cover plate on the shell as the metal heat conducting plate 10, which is convenient for assembly and production. The top of the metal heat conducting plate 10 is fixed with a temperature-controlled electric heating element 7 to control the temperature accurately. The temperature-controlled electric heating element 7 includes an electric heater 13 and a high-temperature temperature control switch 14 and a low-temperature temperature control switch 25, so that when the temperature is detected to be too high above 30 degrees Celsius, the electric heater 13 will stop working, and the high-temperature temperature control switch 14 uses a normally closed 30-degree type switch. When the ambient temperature is too low to below 10 degrees Celsius, the low-temperature temperature control switch 25 will control the temperature-controlled electric heating element 7 to heat up to prevent the outer wall of the cable 5 or the cable 4 from being frozen. The low-temperature temperature control switch 25 uses a normally open 10-degree type switch.

[0044] The power processing unit 8 includes a rectifier 15 , one end of the rectifier 15 is connected to an input wire 23 , and the other end of the rectifier 15 is used as an output end to supply power to each unit through a diode.

[0045] The releaser unit 3 can be a cable releaser unit 11 or a cable releaser unit 12. A cable 4 is fixed in the release hole of the cable releaser unit 11, and a cable 5 is fixed in the release hole of the cable releaser unit 12. The two can be selected according to the needs. The releaser unit 3 is connected to a signal unit through a circuit, and cooperates with a remote controller to realize remote activation of the release unit 3 through the remote controller. The structural principle of the releaser unit can refer to the previous patent technology of the applicant.
