The barrel 1 is used for being sleeved on the outer side of the optical cable 5; the clamping assembly 2 is arranged on the inner wall of the barrel 1 and used for clamping and fixing the optical cable 5 in the barrel 1; the plurality of support rods 3 are arranged on the outer wall of the barrel 1 along the circumferential direction of the barrel 1, and the support rods 3 have freedom degree of movement along the radial direction of the barrel 1; the first elastic reset piece 4 is arranged between the outer wall of the cylinder body 1 and the support rod 3.
Compared with the prior art, the optical cable protection device provided by the invention has the advantages that the optical cable 5 is fixed in the cylinder body 1 by the clamping component 2, and the plurality of support rods 3 play a supporting role in the cylinder body 1; after the cable explodes, barrel 1 removes under the effect of shock wave, and bracing piece 3 bumps with the wall of channel, and first elasticity resets 4 and takes place elastic deformation under the effect of bracing piece 3, has avoided taking place rigid collision between barrel 1 and the channel, has played the cushioning effect to barrel 1, and then has improved barrel 1 to the protection effect of optical cable 5.
In this embodiment, because there is undulation in the ground in the channel, so the PVC sleeve pipe can have unsettled phenomenon, and the local of PVC sleeve pipe can lead to buckling or even breaking owing to unsettled for a long time, can't play the guard action to optical cable 5. By adopting the optical cable protection device, the cylinder body 1 can be prevented from being suspended under the action of the support rod 3 and the first elastic reset piece 4; when a small amount of accumulated water exists in the channel, the supporting rod 3 enables the barrel 1 to be located above the accumulated water level by supporting the barrel 1 to a certain height, so that water is prevented from entering the barrel 1, and the optical cable 5 is protected.
As a specific embodiment of the optical cable protection device provided by the present invention, please refer to fig. 1 and fig. 2, an outer guide support 101 slidably engaged with a support rod 3 is disposed on an outer wall of a cylinder 1, an accommodating cavity is disposed inside the outer guide support 101, a first elastic reset piece 4 is located in the accommodating cavity, one end of the support rod 3 penetrates through a side wall of the accommodating cavity and extends into the accommodating cavity, and the first elastic reset piece 4 abuts against an end surface of the support rod 3. In this embodiment, the outer guide support 101 supports and limits the support rod 3, and ensures the stability of the support rod 3 in the movement process. The outer guide support 101 is fixed with the cylinder 1 by welding. The first elastic return member 4 is a compression spring. Two ends of the compression spring are respectively propped against the end surface of the support rod 3 and the outer wall of the cylinder body 1. The compression spring is always in a compressed state, and exerts an acting force outwards along the radial direction of the cylinder body 1 on the support rod 3. When the support rod 3 is not acted by external force, the support rod 3 is kept relatively stable with the outer guide support 101 under the action of the compression spring. The holding cavity is a closed cavity, the outer guide support 101 separates the compression spring from the outside, the compression spring is protected, and the service life of the compression spring is prolonged.
Referring to fig. 1, 2 and 6, a first air bag 102 is disposed on an outer wall of a cylinder 1, the first air bag 102 is sleeved on an outer guide support 101, and a fixing block 103 for compressing and fixing the first air bag 102 is correspondingly disposed on the outer guide support 101. In this embodiment, when the ponding water level in the channel is higher, first gasbag 102 has increased this optical cable protector's buoyancy to make this optical cable protector float, avoided this optical cable protector to be soaked by ponding completely, reduced this optical cable protector's the possibility of intaking. The first air bag 102 is a ring-shaped member, and is fitted over the outer guide support 101.

In this embodiment, the inner guide support 107 is fixed to the inner wall of the cylinder 1 by welding. The clamping plate 202 is an arc-shaped plate 106, and the telescopic rod 201 is located at the center of the clamping plate 202. The quantity of telescopic link 201 is two at least, and the grip block 202 cooperation on a plurality of telescopic links 201 carries out the centre gripping to optical cable 5 fixed, makes to leave certain clearance between the inner wall of optical cable 5 and barrel 1, even there is a small amount of ponding to enter into the inside of barrel 1, also can be under the effect of gravity, assembles the bottom to barrel 1 along the inner wall of barrel 1, can not exert an influence to optical cable 5. The inner guide support 107 plays a role in guiding and limiting the telescopic rod 201, and the stability of the telescopic rod 201 in the motion process is ensured. The second elastic reset piece 203 is a compression spring, the compression spring is sleeved on the telescopic rod 201, and two ends of the compression spring are respectively abutted against the end surfaces of the inner guide support 107 and the clamping plate 202. The clamping space for accommodating the optical cable 5 is formed by enclosing the plurality of clamping plates 202, and the size of the clamping space can be freely adjusted due to the fact that the compression spring is arranged on one side of each clamping plate 202, so that the optical cables 5 with different radial sizes can be fixed. In the process of cable explosion, the first elastic reset piece 4 has a buffering effect on the cylinder body 1, so that the cylinder body 1 is prevented from shaking violently in the explosion process, and the shock resistance of the cylinder body 1 is improved; owing to set up second elasticity piece 203 that resets between barrel 1 and grip block 202, so even barrel 1 produces rocking of certain range relative optical cable 5, second elasticity piece 203 that resets also can effectively absorb barrel 1's kinetic energy, turns into its elastic deformation to avoid optical cable 5 to rock along with barrel 1, further reduced the impact that causes optical cable 5. The first elastic reset piece 4 is used as a primary buffer, and the second elastic reset piece 203 is used as a secondary buffer, so that the impact on the optical cable 5 in the cable explosion process is reduced to the maximum extent.

In this embodiment, the connecting rod 204 and the telescopic rod 201 form an included angle, and the connecting rod 204 provides an auxiliary supporting effect for the clamping plate 202, so as to prevent the clamping plate 202 from being unstable in stress. The third elastic restoring member 205 is a tension spring. When barrel 1 is impacted by external force and is rocked, telescopic link 201 slides along the direction that is close to the barrel 1 inner wall on direction support 107 including the inertial action, the second elasticity resets and takes place to warp 203 this moment by compressing, and two connecting rods 204 swing to both sides under the drive effect of grip block 202, the third elasticity resets and applies the pulling force to connecting rod 204, can enough guarantee that connecting rod 204 keeps in contact with the inner wall of barrel 1 all the time in the motion process, the biggest swing angle of connecting rod 204 has been restricted again, avoid taking place to break away from with barrel 1 because of connecting rod 204 swing angle is too big. After the connecting rod 204 swings to the maximum included angle, the third elastic resetting piece 205 drives the connecting rod 204 to reset under the action of self elastic force, and the two connecting rods 204 and the second elastic resetting piece 203 exert the action of direction on the clamping plate 202 at the same time, so that the clamping plate 202 and the cylinder 1 move relatively, and the clamping plate 202 is reset. After the elasticity of the second elastic resetting piece 203 fails, the telescopic rod 201 can still realize the telescopic motion on the inner guide support 107 under the action of the connecting rod 204 and the third elastic resetting piece 205, so as to achieve the purpose of buffering the optical cable 5.
