Description

Technical Field

[0001] The present invention relates to the technical field of cable processing and storage, in particular to a storage rack for electric wires and cables with a prolonged service life. Background Art

[0002] With the continuous entry of new brands into the cable market, more and more manufacturers focus on cable quality, taking the high-end quality route to ensure reliable quality and long service life. High-quality products also reduce common fault problems during use. Good acid and alkali anti-corrosion treatment can effectively prevent the insulation layer from being damaged, thereby achieving the effect of protecting the cable. Therefore, not only does the quality need to be improved during cable production, but the cable also needs to be protected during storage to ensure a longer service life and better performance.

[0003] The existing cable storage rack is set in the warehouse and is equipped with desiccant to prevent the cables from getting wet. However, the existing device still has the following defects when in use:

[0004] ① The desiccant installed during the initial storage phase needs to be manually checked regularly to ensure it is fully used. This requires manual inspection and replacement, which not only increases labor costs, but can also lead to the desiccant becoming saturated due to moisture absorption due to delayed manual inspections, thus affecting its effectiveness and causing the cable to become damp. Furthermore, manual inspection cannot ensure that the desiccant is fully utilized. Discarding the desiccant before maximizing its utilization will result in a waste of resources.

[0005] ② If the desiccant is left in the cable storage box for a long time without being replaced in time, moisture may gradually accumulate inside the cable, leading to increased humidity. This not only increases the risk of leakage and shortens the cable life, but also causes the insulation material in the cable to become uneven or lose its insulating ability, making the cable more susceptible to moisture and damage, and even causing safety hazards such as electric shock.

[0006] In view of this, the present invention proposes a storage rack for wires and cables that can extend the service life to compensate for and improve the shortcomings of the prior art. Summary of the Invention

[0007] In order to solve the above technical problems, the present invention provides a storage rack for wires and cables that can extend the service life, so as to solve the corresponding technical problems raised in the above background technology.

[0008] The top end of the motor is fixedly connected to the support rod, and the outer wall of the support rod is fixedly connected to the support rod, and one end of the support rod is screwed to the support rod, and the bottom end of the support rod is rotatably connected to the chassis. The top end face of said sliding panel also is provided with an interlocking structure, and the interlocking structures are pivotally connected to each other with a bolt, and the bolt has a round shank to contact with the interlocking structures.

[0009] As a preferred embodiment of the present invention, the rack rods are evenly and equidistantly distributed on the outer wall of the support rod, the box sleeve is a bilaterally symmetrical hinge structure, and the agent slide ladder is in the shape of an inclined rotating groove.

[0010] As a preferred embodiment of the present invention, the outer wall of the using cavity in the box sleeve is uniformly penetrated with dense small holes and the lower half of the using cavity is opened with a square hole. The using cavity in the box sleeve is filled with a desiccant, and the desiccant is preferably a limestone desiccant.

[0011] As a preferred embodiment of the present invention, teeth are distributed on the side of the lower end of the slide rod 1 close to the push rod 1, and teeth are distributed on the side of the lower end of the slide rod 2 close to the slide rod 1, and the teeth at the lower end of the slide rod are engaged with the teeth at the lower end of the slide rod 2.

[0012] As a preferred embodiment of the present invention, the heat conducting plate is preferably made of ceramic material, a spring is installed in the inner cavity of the heat conducting plate, and the spring is in a natural state, one end of the spring is fixedly connected to the heat conducting plate and the other end is fixedly connected to the push rod.

[0013] As a preferred embodiment of the present invention, the upper end of the ring rod is in a circular ring shape, and the ring rod is initially located on the left side of the horizontal push rod.

[0014] As a preferred embodiment of the present invention, the square slider is in the shape of a square sheet, and the width of the square slider is greater than the diameter of the circular ring at the upper end of the ring rod.

[0015] As a preferred embodiment of the present invention, the early warning mechanism includes an early warning device, a pressing rod, and a warning button. The early warning device is installed on the inner wall of the box sleeve. The side of the push rod 2 away from the horizontal push rod is fixedly connected to the pressing rod. The inner cavity of the box sleeve is provided with a warning button. The warning button is electrically connected to the early warning device, and the warning button is located on the movement trajectory of the pressing rod.

[0016] Compared with the prior art, the beneficial effects achieved by the technical solution of the present invention are:

[0017] (1) The heat released by the desiccant during use causes the memory metal to deform, thereby driving the plate to open and automatically replace the desiccant. This not only avoids the problem of the cable getting damp due to untimely replacement of the desiccant and affecting subsequent use, but also saves labor costs and extends the storage life of the cable. At the same time, automatic replacement of the desiccant can maximize the utilization rate of the desiccant, thereby saving resources and costs.

[0018] (2) By setting up an early warning device, not only is the real-time nature of replacing the desiccant enhanced, the time for manual observation of the desiccant usage status is reduced, thereby saving labor costs, but also the staff does not need to frequently open the cabinet door for inspection, which not only improves work efficiency but also avoids the phenomenon of moisture entering due to frequent opening of the cabinet door, which leads to the reduction of various physical properties of wires and cables, and the reduction of insulation performance of insulating materials, which causes short circuit of wires and cables. It can also prevent external acids, alkalis and corrosive substances from entering the cabinet body, which may damage the cable insulation layer, thereby achieving the effect of protecting the cable;

[0019] (3) The rotation of the support rod drives the rotation of the drying self-processing structure. Since the outer wall of the use cavity is provided with dense small holes, the desiccant installed in the use cavity can fully exert its use function due to its rotation, so that the moisture in the storage cabinet can be fully absorbed, ensuring the dryness of the cabinet body;

[0020] (4) Because the box sleeves are hinged to each other and fixed by a clamp, when the staff needs to add desiccant, they can loosen the clamp to open the box sleeve to complete the addition of desiccant and collect the waste desiccant, which reduces the trouble of the staff to change. In addition, the ring at the upper end of the pull rod can facilitate the staff to lift the square slider to restore it to its original state to ensure the next use.

[0038] The complete usage steps and working principle of the above embodiment are as follows:

[0039] The device is mainly used for: cable storage;

[0040] Initial state: The storage chamber 2101 contains limestone desiccant for replacing the use chamber 2102, the use chamber 2102 contains the desiccant being used, and the anti-drop sheet 1301 is sleeved on the end of the frame rod 13 away from the support rod 12;

[0041] First, the staff needs to open the door of the storage cabinet 1 and manually unscrew the anti-drop sheet 1301 to prepare for putting on the cable. After the rolled cable is put on, the anti-drop sheet 1301 needs to be re-screwed on the rack 13 to prevent the device from being thrown off due to rotation during dehumidification.

[0042] When in use: the staff needs to start the motor 11, at this time the motor 11 will drive the fixedly connected support rod 12 to rotate slowly. Since the support rod 12 is connected to the chassis 14 in rotation, when the support rod 12 rotates, it will drive the rack rod 13 fixedly connected to the support rod 12 to rotate slowly. When the staff has completed sheathing the cable and the anti-slip sheet 1301 on the rack rod 13 facing the cabinet door, because the motor 11 drives the rotation of the support rod 12, there is no need to manually rotate the rack rod 13 to face the cabinet door when sheathing the cable, and the cable on the next rack rod 13 can be completed. When all the rack rods 13 that can be stored in the storage cabinet 1 are sheathed and the anti-slip sheet 1301 for fixing is screwed on, the cabinet door can be closed.

[0043] At this time, the drying self-processing structure 2 is arranged under each layer of cables. When the support rod 12 rotates, the fixed sleeve 23 is fixedly connected to the outer wall of the support rod 12. At this time, the drying self-processing structure 2 is fixedly connected to the outer wall of the fixed sleeve 23. When the fixed sleeve 23 rotates, it will rotate along with it. When the drying self-processing structure 2 rotates, due to the dense small holes on the outer wall of the use cavity 2102, the desiccant installed in the use cavity 2102 will absorb moisture in the air, and the rotation drives the desiccant to move in the use cavity 2102, thereby more fully absorbing moisture.

[0044] When the outside air humidity is high or it is rainy season, the desiccant in the use cavity 2102 absorbs moisture in the air and reaches a saturated state. Due to its own structure, it reacts chemically with water molecules to release heat energy. The released heat energy will reach a certain temperature. In addition, since the use cavity 2102 is provided with a heat conducting sheet 211, and the heat conducting sheet 211 is made of ceramic material, it has the advantage of high thermal conductivity and does not contain insulating metal components, it will not damage the insulation layer outside the cable and cause problems such as line shortage.

[0045] Since a spring is installed in the inner cavity of the heat conducting plate 211, the spring material is nickel-titanium alloy memory metal, and the spring is in a natural state, one end of the spring is fixedly connected to the heat conducting plate 211 and the other end is fixedly connected to the push rod 1 210, so when the heat conduction temperature of the heat conducting plate 211 reaches its deformation temperature, the spring will contract and move the push rod 1 210 to the left. At this time, the slide rod 1 28 and the slide rod 2 29 are both connected to the two flat plates 27 through the shaft rotation. When the push rod 1 210 moves to one side, the teeth at the lower end of the slide rod 1 28 mesh with the teeth at the lower end of the slide rod 29, and the slide rod 2 29 is engaged. The two plates 27 sliding in the slotted plate 26 will be separated from each other by abutting against the slide bar 12, thereby opening the two plates 27. Since the lower half of the use chamber 2102 is provided with a square hole, when the plates 27 are opened, the rotation of the support rod 12 will drive the fixed sleeve 23 fixedly connected to the outside thereof to rotate, and the agent sliding ladder 24 fixedly connected to the outer wall of the fixed sleeve 23 will rotate accordingly. The used desiccant will then roll down the agent sliding ladder 24 to the waste chamber 2103 by the force of the rotation of the agent sliding ladder 24, and be used to collect the waste desiccant.

[0046] Since the ring rod 212 is fixedly connected to the upper surface of the first push rod 210, when the plate 27 is in the open state, the upper end of the ring rod 212 will slide on the outer wall of the horizontal push rod 213 and detach from the horizontal push rod 213. At this time, since the square slider 214 slides on the side of the ring rod 212 close to the second push rod 216, when the square slider 214 detaches from the horizontal push rod 213, it will slide downward to block one side of the ring rod 212.

[0047] When the used desiccant falls into the waste chamber 2103, the temperature in the use chamber 2102 will drop to normal room temperature. At this time, the memory metal will return to its initial state, and the ring rod 212 will move to the side close to the second push rod 216. Because the square slider 214 seals one side of the ring rod 212, the square slider 214 will use the horizontal push rod 213 to make the second push rod 216 move to the side close to the pressing rod 32. Because the mechanism on the upper surface of the use chamber 2102 is mirror-symmetrical with the mechanism on the lower surface, the two flat plates 27 on the lower surface of the use chamber 2102 are closed while the mechanism on its upper surface is in an open state. At this time, the unused desiccant in the storage chamber 2101 will rotate and fall into the use chamber 2102 through the agent body sliding ladder 24, so as to complete the automatic replacement of the desiccant. This not only avoids the problem that the cable is damp and affects the subsequent use due to untimely replacement of the desiccant, but also saves labor costs and extends the service life of the cable storage.

[0048] When the desiccant in the use chamber 2102 is completely replaced, the movement of the push rod 216 causes the pressing rod 32 fixedly connected to one side thereof to move toward the box sleeve 21. Since the warning button 33 is provided on the inner wall of the box sleeve 21 and is located on the movement trajectory of the pressing rod 32, the warning button 33 is electrically connected to the warning device 31. When the pressing rod 32 moves toward the box sleeve 21 and touches the warning button 33, the warning device 31 located on the upper surface of the box sleeve 21 is triggered. At this time, the warning device 31 emits a sound to remind the staff to dispose of the waste desiccant and add new spare desiccant to replace the used desiccant in the use chamber 2102. Since the box sleeve 21 is hinged to each other and fixed by the clamp 22, when the staff needs to add desiccant, they can loosen the clamp 22 to open the box sleeve 21 to complete the addition of desiccant and collect the waste desiccant.

[0049] In addition, the function of the pull rod 215 is to fix the square slider 214 in the required position so as to carry out relevant operations. The staff can lock or release the square slider 214 by pulling the pull rod 215. The square slider 214 will be located on one side of the ring rod 212 and stuck during use. At this time, the staff can manually pull up the square slider 214 to restore it to its original state for the next use. The purpose of setting the pull rod 215 is to facilitate the operation of the staff and ensure that the square slider 214 can be fixed in the required position, so as to facilitate relevant operations and avoid obstruction or jamming.

[0050] By setting up the early warning mechanism 3, not only the real-time performance of desiccant replacement is enhanced, the time for manual observation of the desiccant usage status is reduced, thereby saving labor costs, but also the staff does not need to frequently open the cabinet door for inspection, which not only improves work efficiency but also avoids moisture entering due to frequent opening of the cabinet door, thereby extending the storage and use period of the cable.

[0051] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
