[0021] The implementation details of the technical solution of the embodiment of the present application are described in detail below:

[0022] First of all, it should be noted that the automatic cable retraction device proposed in the present application can be applied to the technical field of dry gas tanks. For example, the cables used to connect the top of the dry gas tank and the equipment on the piston often cause safety problems due to the problem of scattering. Therefore, automatic cable retraction is particularly important.

[0023] According to one aspect of the present application, there is provided an automatic cable retracting and releasing device. Figure 1 This is a schematic diagram of the structure of an automatic cable retracting and releasing device according to an embodiment of the present application, which is described in detail as follows:

[0024] Please refer to Figure 1 A device for automatically retracting and releasing a cable 50 includes a wire reel 10, a wire drum 40, an energy storage assembly 30, and a retractor 20. The wire reel 10 is a container with an opening at one end. The wire drum 40 is fixed in the wire reel 10. A wire retracting cavity is formed between the wire reel 10 and the wire drum 40. The energy storage assembly 30 is arranged on the wire drum 40. When the energy storage assembly 30 rotates in one direction, potential energy can be stored. When the energy storage assembly 30 rotates in the opposite direction, potential energy can be released. The retractor 20 is connected to the energy storage assembly 30. The retractor 20 is provided with a first threading hole 26 and a second threading hole 26. There are two threading holes 27, the axis of the first threading hole 26 and the axis of the second threading hole 27 are not on the same vertical line, and a preset height difference is set between the first threading hole 26 and the second threading hole 27. One end of the cable 50 is fixed to the cabinet top of the dry gas cabinet, and the other end of the cable 50 passes through the first threading hole 26 and the second threading hole 27 and is arranged in the wire taking-up cavity and connected to the electrical equipment. When the cable 50 is stretched and unfolded, the retractor 20 rotates, and the energy storage component 30 stores potential energy. When the cable 50 is stored, the energy storage component 30 releases the potential energy to store the cable 50 in the wire taking-up cavity.

[0025] In the present application, the cable 50 is used to connect the working box on the top of the dry gas cabinet and the equipment on the piston. Since the distance between the piston and the top of the dry gas cabinet changes during the process of storing and releasing gas, the required length of the cable 50 also changes.

[0026] When the piston moves away from the top of the dry gas tank, the length of the cable 50 required between the piston and the top of the dry gas tank needs to be extended, and the cable 50 is stretched. During the process of pulling the cable 50 outward, since the axes of the first threading hole 26 and the second threading hole 27 are not on the same vertical line, during the process of the cable 50 being stretched outward, the cable 50 drives the retractor 20 to rotate, and the retractor 20 drives the energy storage assembly 30 to rotate. At this time, the energy storage assembly 30 converts kinetic energy into elastic potential energy for storage.

[0027] When the piston moves toward the top of the dry gas tank, the length of the cable 50 required between the piston and the top of the dry gas tank needs to be shortened, the force of the piston pulling the cable 50 is released, and the energy storage component 30 rotates in the opposite direction of energy storage. The energy storage component 30 rotates, driving the retractor 20 to rotate, and the cable 50 is retracted into the retracting cavity. The extension and storage of the cable 50 are automatically balanced by the pulling force between the energy storage component 30 and the piston on the cable 50, realizing the automatic mechanized storage and extension of the cable 50.

[0028] In one embodiment of the present application, the wire drum 40 is conical, and the diameter of the wire drum 40 gradually increases from the opening to the bottom of the wire take-up drum 10 .

[0029] In the present application, the cable drum 40 is conical in shape, which is beneficial for storing and unfolding the cable 50 .

[0030] In one embodiment of the present application, the energy storage assembly 30 includes an energy storage spring 32 and a rotating shaft 31. The spring 32 is arranged on the wire drum 40. The inner side of the spring 32 is fixed to the rotating shaft 31. One end of the rotating shaft 31 is fixed to the retractor 20. When the retractor 20 rotates, the rotating shaft 31 is driven to rotate.

[0031] In the present application, the mainspring 32 can store kinetic energy as elastic potential energy, and can also convert elastic potential energy into kinetic energy.

[0032] In one embodiment of the present application, the distance between the axes of the first threading hole 26 and the second threading hole 27 is 50-70 mm.

[0033] In the present application, the distance between the axes of the first threading hole 26 and the second threading hole 27 is 50-70 mm. When the cable 50 is unfolded and moved, an eccentric force is formed between the first threading hole 26 and the second threading hole 27, so that the cable 50 drives the retractor 20 to rotate.

[0034] In one embodiment of the present application, the height difference between the first threading hole 26 and the second threading hole 27 is 20-30 mm.

[0035] In the present application, when the height difference between the first threading hole 26 and the second threading hole 27 is within this range, the cable 50 can move more smoothly from the first threading hole 26 to the second threading hole 27 .

[0036] In one embodiment of the present application, the retractor 20 includes a first fixing portion 211, a second fixing portion 23, a third fixing portion 25, a first connecting portion 22 and a second connecting portion 24. The first fixing portion 211 and the second fixing portion 23 are connected via the first connecting portion 22, and the second fixing portion 23 and the third fixing portion 25 are connected via the second connecting portion 24. The first fixing portion 211, the second fixing portion 23 and the third fixing portion 25 are parallel to each other.

[0037] The first threading hole 26 is disposed on the first fixing portion 211 , the second threading hole 27 is disposed on the third fixing portion 25 , and the rotating shaft 31 is connected to the second fixing portion 23 .

[0038] In the present application, the retractor 20 is a sheet-like structure with a thickness of 5-10 mm, which can effectively ensure the overall working strength. The first fixing part 211 and the second fixing part 23 are parallel, and the rotating shaft 31 is fixed to the second fixing part 23, and the rotating shaft 31 is fixed to the second fixing part 23 vertically.

[0039] In one embodiment of the present application, the axis of the second threading hole 27 and the axis of the rotating shaft 31 are on the same vertical line.

[0040] In the present application, the axis of the second threading hole 27 is on the same vertical line as the axis of the shaft 31 , and the rotation axis of the shaft 31 is consistent with the rotation axis of the retractor 20 , thereby reducing the resistance of the cable 50 to the rotation of the retractor 20 .

[0041] In the technical solution of the embodiment of the present application, when the piston of the dry gas tank descends, that is, when the chemical gas such as coal gas is discharged, the piston is away from the top of the dry gas tank, and the cable 50 is extended and unfolded. During the pulling process of the cable 50, the first threading hole 26 and the second threading hole 27 form an eccentric hole, which causes the retractor 20 to rotate during the pulling process of the cable 50. The cable 50 pulls up the retractor 20 and drives the energy storage component 30 to rotate. At this time, the energy storage component 30 stores potential energy. When the piston approaches the top of the dry gas tank, the distance between the piston and the top of the dry gas tank becomes shorter, and the lifting force of the piston cable 50 decreases. At this time, the energy storage component 30 releases potential energy, drives the rotating shaft 31 to rotate, and the retractor 20 rotates with the rotating shaft 31, so that the cable 50 is stored in the retracting cavity formed between the retracting barrel 10 and the coiling barrel 40, so as to realize the storage of the cable 50. The length of the cable 50 can be automatically released and stored according to actual usage, which effectively protects the cable 50 and prevents the cable 50 from being scattered and tangled or hanging on other components, thereby improving the overall operating stability and overall safety performance.

[0042] It should be understood that the present application is not limited to the precise structures that have been described above and shown in the drawings, and that various modifications and changes may be performed without departing from the scope thereof. The scope of the present application is limited only by the appended claims.
