Description

Technical Field

[0001] The utility model relates to the technical field of repeaters, and particularly relates to a intrinsically safe mine repeater. Background Art

[0002] A repeater (RP repeater) is a connection device operating at the physical layer, suitable for interconnecting two exactly the same networks. Its main function is to expand the network transmission distance by retransmitting or forwarding data signals.

[0003] The intrinsically safe repeater is a repeater applied to mining areas. Due to the relatively complex mining environment, there are usually many devices working simultaneously, which causes the intrinsically safe repeater to vibrate under the influence of other devices. Since most of these repeaters are connected to cables through threads, although the threaded connection is very convenient, it is easy to cause the connection to loosen or even fall off in case of frequent vibration. Therefore, an intrinsically safe mine repeater is proposed to solve the above-mentioned problems. Summary of the Utility Model

[0004] Based on the above description, the utility model provides an intrinsically safe mine repeater to solve the problem that the existing intrinsically safe repeater is prone to loosen when thread-connected to a cable under frequent vibration.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: An intrinsically safe mine repeater includes a repeater main body and a positioning and buffering member. The positioning and buffering member includes a fixed base, a cover plate, a positioning member, and a buffering member. The fixed base is arranged on the upper surface of the repeater main body and includes a first movable groove, a magnet groove, a permanent magnet, and a second movable groove. The permanent magnet is arranged inside the magnet groove. The cover plate is arranged at the top of the fixed base. The buffering member is arranged inside the first movable groove and extends above the cover plate, and includes a damping block, a winding cylinder, and a second spring. The positioning member is arranged inside the second movable groove and extends above the cover plate, and includes a vertical movable member, a clamping member, and a first spring.

[0006] On the basis of the above technical solution, the utility model can be further improved as follows.

[0007] Further, the fixed base includes a base block. The upper surface of the base block is provided with a first movable groove, a magnet groove, and a second movable groove. The magnet grooves are annularly and equidistantly distributed along the outer edge of the first movable groove. The inner wall of the second movable groove is provided with protrusions.

[0008] Further, the cover plate includes a plate. The upper surface of the plate is provided with a first through hole and a second through hole, which respectively correspond to the first movable groove and the second movable groove.

[0009] Furthermore, a contact sleeve is provided on the lower surface of the plate, and the contact sleeve corresponds to the first through hole.

[0010] Furthermore, the damping block includes a friction block which is arranged inside the first movable groove and penetrates through the first through hole.

[0011] Furthermore, a metal block is provided at the bottom end of the friction block, spaced openings are provided on the outer surface of the metal block, a vertical rod is provided at the top end of the friction block, and a second spring is provided between the metal block and the fixed base.

[0012] Furthermore, the winding cylinder includes a cylinder body which is arranged at the top end of the damping block by screws, and a winding groove is provided on the outer surface of the cylinder body.

[0013] Furthermore, the vertical movable member includes a movable plate which is arranged inside the second movable groove, a groove is provided on the outer surface of the movable plate, and a connecting column penetrating through the second through hole is provided at the top end of the movable plate.

[0014] Furthermore, the clamping member includes a clamping block, an inclined surface is provided on one side of the clamping block close to the winding cylinder, a U-shaped opening is provided on the surface of the clamping block, and the clamping block is arranged at the top end of the vertical movable member by screws.

[0015] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:

[0016] 1. By providing components such as a clamping member, a vertical movable member and a first spring, and through the mutual cooperation of the above three components, when the cable passes through the U-shaped opening and is threadedly connected to the repeater main body, the vertical movable member clamps the connector of the cable, so that there is no margin for the connector of the cable to move towards the winding cylinder direction, thereby preventing the connector from loosening or even detaching.

[0017] 2. By providing the damping block, the winding cylinder and the permanent magnet, it is realized that when the cable is connected to the repeater, a part of the cable can be wound inside the winding groove. When the cable is pulled by an external force, the cable drives the winding cylinder and the damping block to rotate under the action of the pulling force. At this time, the damping block generates a damping phenomenon under the action of the permanent magnet to consume the external pulling force, thereby preventing the cable and the repeater from being damaged by a sudden external pulling force.

It should also be understood that the terms "comprising" or "having" or the like specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0033] Please refer to Figures 1-4 , a intrinsically safe repeater for mining, comprising:

[0034] A repeater body 1;

[0035] A fixed base 2, which is arranged on the upper surface of the repeater body 1 and includes a first movable slot 22, a magnet slot 23, a permanent magnet 24 and a second movable slot 25;

[0036] The fixed base 2 includes a base block 21. The upper surface of the base block 21 is provided with a first movable slot 22, a magnet slot 23 and a second movable slot 25. The magnet slots 23 are annularly and equidistantly distributed along the outer edge of the first movable slot 22. The inner wall of the second movable slot 25 is provided with protrusions, and the permanent magnet 24 is arranged inside the magnet slot 23;

[0037] Based on the above, the permanent magnet 24 provides a magnetic field, causing a magnetic damping phenomenon when the damping block 4 rotates, thereby consuming and buffering external forces. The setting of the protrusions plays a limiting role on the vertical moving part 6, making the vertical moving part 6 only able to move vertically and unable to rotate.

[0038] As Figures 2-6 shown, a cover plate 3, which is arranged at the top of the fixed base 2. The cover plate 3 includes a plate 31. The upper surface of the plate 31 is provided with a first through hole 32 and a second through hole 34. The first through hole 32 and the second through hole 34 respectively correspond to the first movable slot 22 and the second movable slot 25. The lower surface of the plate 31 is provided with a contact sleeve 33, and the contact sleeve 33 corresponds to the first through hole 32;

[0039] Based on the above, the cover plate 3 plays a role in closing the fixed base 2, preventing the permanent magnet 24, the positioning part and the buffer part from detaching from the fixed base 2.

[0040] As Figure 2 ,Figure 3 , Figure 7 and Figure 8 As shown in Figure 3 , Figure 7 and Figure 8 , the buffer member is disposed inside the first movable slot 22, extends above the cover plate 3, and includes a damping block 4, a winding cylinder 5 and a second spring 9;

[0041] The damping block 4 includes a friction block 41 which is disposed inside the first movable slot 22, penetrates through the first through hole 32. A metal block 42 is provided at the bottom end of the friction block 41, spaced openings 43 are provided on the outer surface of the metal block 42, a vertical rod 44 is provided at the top end of the friction block 41, and a second spring 9 is provided between the metal block 42 and the fixed base 2;

[0042] The winding cylinder 5 includes a cylinder body 51 which is disposed at the top end of the damping block 4 by screws, and a winding groove 52 is provided on the outer surface of the cylinder body 51;

[0043] Based on the above, the friction block 41 is in contact with the inner wall of the contact sleeve 33 under the upward elastic force of the second spring 9 to provide friction, so that the buffer member is not easy to rotate. The metal block 42 and the spaced openings 43 are provided so that the damping block 4 can generate a magnetic damping phenomenon when rotating inside the permanent magnet 24 to buffer and consume external forces. The winding groove 52 is provided so that the cable can be wound on the outer surface of the winding cylinder 5, and the winding cylinder 5 can be driven to rotate when the cable is pulled by an external force.

[0044] As Figure 2 , Figure 3 , Figure 9 and Figure 10 As shown in Figure 2 , Figure 3 , Figure 9 and Figure 10 , the positioning member is disposed inside the second movable slot 25, extends above the cover plate 3, and includes a vertical movable member 6, a clamping member 7 and a first spring 8;

[0045] The vertical movable member 6 includes a movable plate 61 which is disposed inside the second movable slot 25. Grooves 62 are provided on the outer surface of the movable plate 61, and a connecting column 63 penetrating through the second through hole 34 is provided at the top end of the movable plate 61;

[0046] The clamping member 7 includes a clamping block 71. An inclined surface 72 is provided on one side of the clamping block 71 close to the winding cylinder 5. A U-shaped opening 73 is provided on the surface of the clamping block 71, and the clamping block 71 is disposed at the top end of the vertical movable member 6 by screws;

[0047] Based on the above, the vertical moving part 6 and the second moving slot 25 cooperate with each other, enabling the vertical moving part 6 to move only vertically. The U-shaped opening 73 allows the cable to pass through the clamping part 7. When the cable connectors are squeezed by the clamping part 7, the clamping part 7 moves downward under the action of the inclined surface 72, enabling the cable to pass through the clamping part 7 normally and then connect to the connection part of the repeater body 1. After the connection is completed, the clamping part 7 resets under the action of the first spring 8, achieving the effect of limiting the connection part.

[0048] When the present utility model is actually used, by providing a buffer part, the cable can be wound inside the winding slot 52 when connecting to the repeater body 1. On the one hand, a margin is preset for the cable, enabling the cable to stretch normally when subjected to an external pulling force. On the other hand, in cooperation with the winding slot 52, the cable can drive the winding cylinder 5 to rotate when being pulled;

[0049] When the winding cylinder 5 rotates, it drives the damping block 4 to rotate together. Since the damping block 4 needs to overcome the friction force between it and the contact sleeve 33 when rotating, a relatively large external force is required to pull it. When the damping block 4 rotates, the metal block 42 rotates inside the permanent magnet 24, and the external force is consumed under the action of the magnetic damping phenomenon. Here, the metal block 42 is preferably made of a metal that cannot be magnetized, such as aluminum;

[0050] The U-shaped opening 73 allows the cable to pass through the clamping part 7. When the cable connectors are squeezed by the clamping part 7, the clamping part 7 moves downward under the action of the inclined surface 72, enabling the cable to pass through the clamping part 7 normally and then connect to the connection part of the repeater body 1. After the connection is completed, the clamping part 7 resets under the action of the first spring 8, achieving the effect of limiting the connection part. When the connector loosens under the action of vibration, due to the lack of movement margin, the movement of the connector is blocked, enhancing the connection effect;

[0051] By providing a clamping part 7 at the connection between the repeater and the cable, the device prevents the connector from loosening, achieving the effect of enhancing the connection. And the cable is protected by the buffer part to avoid damage to the cable and the repeater body 1 when suddenly pulled by an external force.

[0052] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
