Multiple support components are arranged along the length of the first protective tube at its bottom. A bracket is provided at one end of the top of each support component, and the second protective tube is positioned on top of the bracket. Each bracket corresponds to one of the support components, and joints are provided at both ends of the second protective tube. The parallel arrangement of the first and second protective tubes allows for the addition of cables within the first protective tube. Since it is difficult to add new cables within the first protective tube when multiple cables are already installed, the newly added cables can be threaded into the second protective tube, improving threading efficiency. Furthermore, the joints at both ends of the first protective tube allow for flexible extension of the second protective tube's length, providing greater flexibility. The support components at the bottom of the first protective tube and the bracket at the bottom of the second protective tube enhance the stability of the first and second protective tubes.

[0004] The device is equipped with a structure to increase the stability of the cable connection, but it does not have a vibration damping structure. The underground environment of coal mines is complex and contains various vibration sources, such as the vibration of drilling rigs, the flow of groundwater, and earthquakes. These vibrations may damage the cables, such as squeezing, twisting, or breaking.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing structure of underground cable protection devices in coal mines. Utility Model Content

[0010] Preferably, the shock absorption assembly further includes a support rod, which is rotatably connected to the outside of the sliding block, and the upper end of the support rod is rotatably connected to the bottom of the storage frame; this structure allows the sliding block to slide left and right inside the groove by rotating the support rod.

[0011] Preferably, the support rods are arranged in two sets symmetrically about the midpoint of the storage frame; this structure, with two sets of support rods symmetrically about the midpoint of the storage frame, can support the upper storage frame.

[0012] Preferably, the protective assembly includes a concentric shaft, a protective cover, and a gasket. The concentric shaft is fixedly installed on the outside of the storage frame, and the protective cover is rotatably connected to the outside of the concentric shaft. A gasket is fixedly installed on the inside of the protective cover. This structure allows the protective cover to rotate via the concentric shaft, thus protecting the outside of the cable body.

[0013] Preferably, the protective component further includes a slot, which is formed inside the protective cover; this structure can be engaged with the tail end of the lever through a snap-fit ​​mechanism.

[0014] Preferably, the protective assembly further includes a fixing plate, a telescopic spring, and a locking rod. The fixing plate is fixedly installed on the outside of the storage frame, and a telescopic spring is fixedly connected to the outside of the fixing plate. A locking rod is fixedly connected to the tail end of the telescopic spring, and the locking rod passes through the inside of the fixing plate. The tail end of the locking rod is engaged with the inside of the slot. This structure can fix the protective cover to the upper end of the storage frame through the engagement of the slot and the tail end of the locking rod.

[0015] Compared with the prior art, the beneficial effect of this utility model is that the underground cable protection device in the coal mine is equipped with:

[0016] 1. Vibration damping structure: When strong vibrations occur in the coal mine, the frame will sway up and down, which will drive the support rod at the lower end to rotate. The rotation of the support rod will drive the sliding blocks on both sides to slide along the inner side of the slide groove, thereby squeezing the damping spring. At this time, the damping spring is responsible for bearing the load and transmitting pressure, while the damper connected to it reduces vibration and impact by consuming energy, thus effectively absorbing and dispersing these vibration energies, thereby protecting the cable from damage.

[0017] 2. Protective Structure: After the cable body is laid, manually pull the lever, and then rotate the protective cover through the concentric shaft to make the protective cover fit against the upper end of the cable body, protecting the upper end of the cable body and preventing leakage caused by compression or wear on the outside of the cable body. After fitting, release the lever, and the lever will reset by the elastic force of the telescopic spring, thereby engaging with the corresponding slot on the inside of the protective cover. The engagement of the lever and the slot will fix the protective cover. Attached Figure Description

The protective component 5 also includes a fixing plate 505, a telescopic spring 506 and a locking rod 507. The fixing plate 505 is fixedly installed on the outside of the storage frame 2, and the telescopic spring 506 is fixedly connected to the outside of the fixing plate 505. The locking rod 507 is fixedly connected to the tail end of the telescopic spring 506, and the locking rod 507 passes through the inside of the fixing plate 505. The tail end of the locking rod 507 is engaged with the inside of the slot 504.

[0030] After the cable body 3 is laid, manually pull the lever 507, and then rotate the protective cover 502 through the concentric shaft 501 so that the protective cover 502 fits against the upper end of the cable body 3, protecting the upper end of the cable body 3 and preventing leakage caused by compression or wear on the outside of the cable body 3. After fitting, release the lever 507, and the lever 507 will be reset by the elastic force of the telescopic spring 506, thereby engaging with the corresponding slot 504 on the inner side of the protective cover 502. The engagement of the lever 507 with the slot 504 fixes the protective cover 502.
