Description

Technical Field

[0001] The present invention relates to the technical field of optical cable distribution boxes, and particularly to an optical cable distribution box with a hierarchical heat dissipation function. Background Art

[0002] An optical cable distribution box is a connection device that provides optical cable termination and cross-connection for backbone optical cables and distribution optical cables. The optical cable distribution box is mainly used as an interface device at the junction of the backbone optical cable and the distribution optical cable in the optical cable access network. The structure of the optical cable distribution box mainly consists of a box body, internal metal parts, optical fiber active connectors, and equipment accessories. A large number of optical cables and optical devices are integrated inside the optical cable distribution box, and these devices will generate a large amount of heat during operation. If the heat cannot be dissipated in time, it will lead to a decline in equipment performance, and even cause failures, affecting the stability and reliability of the entire communication network.

[0003] The traditional heat dissipation method for optical cable distribution boxes is to use a heat dissipation fan or directly blow air into the box to achieve heat dissipation inside the entire optical cable distribution box. However, the air outlet and air outlet direction inside the optical cable distribution box are fixed and unchanged, and only local components or components close to the air outlet can be dissipated, while the heat dissipation effect of components far from the air outlet is poor; the internal environment ventilation is poor after some boxes are closed, and the direct blowing of air may cause hot air to stay inside and cannot effectively dissipate heat. Moreover, the traditional optical cable distribution box is not convenient for targeted heat dissipation for some compartments according to needs and cannot be flexibly adjusted according to actual requirements. Therefore, the existing heat dissipation methods for optical cable distribution boxes cannot meet the requirements and are not conducive to actual use. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is reasonably arranged and has strong functionality, and has the following advantages: 1. Wind blows into the air guiding pipeline along the air inlet pipe, enters the docking head along the air guiding pipeline and the docking pipe, the wind enters the inner cavity of the connecting pipe along the docking head. At this time, the conical plug is separated from the conical groove, and the wind passes through the rotating seat and the rotary joint along the connecting pipe and enters the inner cavity of the air outlet pipe. Then the wind blows downward along the air outlet and the sector-shaped opening, so as to dissipate heat from the components in the inner cavity of the optical cable cross-connect box.

[0015] 2. The driving mechanism makes the transmission mechanism move left and right reciprocally. The transmission mechanism makes the air outlet pipe swing left and right along the circular groove, causing the air outlet at the lower end of the air outlet pipe to swing left and right. Thus, the air can be blown out in a swinging manner along the air outlet, enabling the air to evenly dissipate heat from the components, and thereby greatly improving the heat dissipation effect on the components.

[0016] 3. Due to the suction force generated by the negative pressure pump, the heat dissipated by the components and the air blown over the components enter the main suction pipe along the suction branch pipes. At this time, the air in the main suction pipe is sucked away by the negative pressure pump along the suction pipe and the extension pipe. By using the combination of blowing and suction to form an efficient air duct, the components in the optical cable distribution box can be efficiently cooled, with the air intake slightly greater than the air exhaust to reduce dust accumulation.

[0017] 4. When components are installed below a certain air outlet mechanism, the adjusting mechanism drives the air outlet pipe to move forward, causing the conical plug to seal one end of the connecting pipe. At this time, the air will not enter the rotating seat along the connecting pipe, that is, the air outlet in this air outlet mechanism will not blow air downward. When the air outlet mechanism needs to blow air, the adjusting mechanism drives the air outlet pipe to move backward, causing the conical plug to release the seal of the connecting pipe. At this time, the air can enter the rotating seat along the connecting pipe, enabling the air outlet of the air outlet mechanism to blow air normally. By the cooperation of the provided adjusting mechanism and the sealing component, it is possible to adjust whether a certain air outlet mechanism can blow air according to the actual situation. When no components are installed below the air outlet mechanism, the air outlet mechanism does not blow air, improving the utilization rate of resources. BRIEF DESCRIPTION OF THE DRAWINGS

The driving mechanism is used to drive the transmission mechanism to move left and right reciprocally.

[0022] Please refer to Figure 2 and Figure 3 , a plurality of groups of guide rails 11 are fixedly installed in the inner cavity of the optical cable distribution box body 1. The number of groups of guide rails 11 is the same as the number of partition plates 3. The number of each group of guide rails 11 is two. The two guide rails 11 of each group are symmetrically distributed on both ends of the partition plate 3. Guide grooves 31 are symmetrically opened at both left and right ends of the partition plate 3. The rear end of the guide groove 31 penetrates through the partition plate 3 backward, and the front end of the guide groove 31 is a closed end. The guide groove 31 is movably inserted with the adjacent guide rail 11. The front end of the guide rail 11 and the partition plate 3 are fixedly connected through a locking screw 12. By setting the locking screw 12, the partition plate 3 and the guide rail 11 are relatively fixed, so that the partition plate 3 and the optical cable distribution box body 1 are relatively fixed, and the partition plate 3 is firmly installed in the inner cavity of the optical cable distribution box body 1.

[0023] The partition plate 3 is horizontally inserted into the inner cavity of the optical cable cross-connect box body 1, so that the two guiding grooves 31 on the left and right sides of the partition plate 3 are stuck on the two guide rails 11, and the partition plate 3 is inserted backward along the guide rails 11 until the front end of the guide rail 11 abuts against the closed end of the guiding groove 31.

The lower end of the strip-shaped groove 36 is communicated with the circular groove 33 through a communication groove; The docking mechanism is installed in the installation groove 32, the air outlet mechanism is installed in the circular groove 33, and the transmission mechanism is installed in the strip-shaped groove 36; The docking mechanism includes a connecting pipe 5 fixedly installed in the installation groove 32. One end of the connecting pipe 5 close to the recessed groove is fixedly connected with a docking head 51, the other end of the connecting pipe 5 is fixedly connected with a rotating seat 52. The docking head 51 is inserted into the docking pipe 22. A rubber sleeve is fixedly installed in the inner cavity of the docking pipe 22. The docking head 51 is inserted into the inner cavity of the rubber sleeve. Through the arranged rubber sleeve, the docking head 51 is hermetically connected with the docking pipe 22. The two ends of the connecting pipe 5 are respectively communicated with the inner cavities of the docking head 51 and the rotating seat 52, and a closing assembly is installed in the inner cavity of the connecting pipe 5.

[0025] When the partition plate 3 moves backward, it drives the docking mechanism to move backward synchronously until the rear side of the partition plate 3 contacts the side surface of the air guide pipe 21, so that the docking pipe 22 is inserted into the recessed groove, and at the same time, the docking head 51 of the docking mechanism is inserted into the docking pipe 22.

[0026] The closing assembly includes a positioning frame 53 fixedly connected to the inner cavity of the connecting pipe 5. A polygonal groove is penetrated through the side surface of the positioning frame 53. A polygonal column 54 is slidably inserted into the inner side of the polygonal groove.

A conical groove is arranged at one end of the connecting pipe 5 close to the rotating seat 52, and the conical groove matches with the conical plug 55.

[0027] When the closing assembly seals the connecting pipe 5, under the action of the elastic force of the return spring 56, the conical plug 55 is inserted into the conical groove, and the conical groove is sealed by the conical plug 55, so as to seal one end of the connecting pipe 5 close to the rotating seat 52, and prevent air from entering the rotating seat 52 along the connecting pipe 5.

[0028] The air outlet mechanism includes an air outlet pipe 4 movably installed in the circular groove 33. The air outlet pipe 4 can slide back and forth and rotate along the circular groove 33. A plurality of air outlet openings 41 are equidistantly arranged at the lower end of the air outlet pipe 4. The air outlet openings 41 communicate with the fan-shaped opening 34. One end of the air outlet pipe 4 close to the rotary seat 52 is fixedly connected with a rotary joint 42. The rotary joint 42 is inserted into the inner cavity of the rotary seat 52. The inner side of the rotary joint 42 is fixedly connected with a push rod 57 through a connecting block. One end of the push rod 57 passes through the rotary joint 42 and extends to the outside.

[0029] When the rotary joint 42 is inserted into the rotary seat 52, at this time, the rotary joint 42 drives the push rod 57 to insert into the inner cavity of the connecting pipe 5. By pushing the push rod 57, the tapered plug 55 moves away from the tapered groove until the tapered plug 55 moves away from the tapered groove, so that the tapered plug 55 releases the seal of the tapered groove. At this time, the air can enter the rotary seat 52 along the connecting pipe 5, then enter the rotary joint 42 along the rotary seat 52, then enter the inner cavity of the air outlet pipe 4 along the rotary joint 42, and the air blows downward along the air outlet openings 41 and the fan-shaped opening 34, so as to dissipate heat from the components in the inner cavity of the optical cable cross-connect box 1.

The front end of the round rod is fixedly connected with a knob 61. The knob 61 is rotatably installed in the knob groove. A rectangular seat 62 is slidably installed back and forth in the rectangular groove 35. A threaded hole 63 is formed through the side surface of the rectangular seat 62. The adjusting screw rod 6 is threadedly connected with the threaded hole 63; On the rear side of the rectangular seat 62, sector-shaped side plates 64 are symmetrically fixedly connected left and right. Sector-shaped grooves 65 are formed on the inner sides of the two sector-shaped side plates 64. An annular plate 66 is rotatably installed between the two sector-shaped grooves 65. The annular plate 66 is fixedly sleeved on the outer side of the air outlet pipe 4.

[0031] By rotating the knob 61 clockwise or counterclockwise, the knob 61 drives the adjusting screw rod 6 to rotate through the round rod. The adjusting screw rod 6 rotates along the threaded hole 63, so that the rectangular seat 62 moves forward or backward along the rectangular groove 35. The rectangular seat 62 drives the annular plate 66 to move forward or backward synchronously through the sector-shaped side plates 64. The annular plate 66 drives the air outlet pipe 4 to move forward or backward along the circular groove 33.

[0032] When the air outlet pipe 4 moves forward, the air outlet pipe 4 drives the rotary joint 42 to slowly separate from the rotary seat 52. At this time, the rotary joint 42 drives the push rod 57 to move out of the inner cavity of the connecting pipe 5, so that the push rod 57 releases the push on the tapered plug 55. Under the action of the elastic force of the return spring 56, the tapered plug 55 seals one end of the connecting pipe 5.

[0033] When the air outlet pipe 4 moves backward, the air outlet pipe 4 drives the rotary joint 42 to be inserted into the rotary seat 52 slowly. At this time, the rotary joint 42 drives the push rod 57 to insert into the inner cavity of the connecting pipe 5, so that the push rod 57 pushes the tapered plug 55 to separate from the tapered groove, and the tapered plug 55 releases the seal on the connecting pipe 5.

[0034] Please refer to Figure 5 、 Figure 6 、 Figure 10 and Figure 11 As shown in, the transmission mechanism includes a strip plate 7 slidably mounted left and right in the strip groove 36.

A through groove is formed outward at the innermost end of the limiting groove. The L-shaped clamping plate 74 is slidably connected left and right with the through groove.

[0035] When the partition plate 3 is disassembled and installed, one end of the strip plate 7 is flush with one end of the strip groove 36 at this time, and at the same time, the L-shaped clamping plate 74 is outside the strip groove 36. At this time, the L-shaped clamping plate 74 can slide back and forth along the limiting groove, so that the L-shaped clamping plate 74 will not hinder the disassembly and installation of the partition plate 3.

[0036] By driving the strip plate 7 to slide left and right along the strip groove 36 through the L-shaped clamping plate 74, the strip plate 7 drives the toothed plate 72 to move left and right synchronously. The toothed plate 72 drives the semi-circular gear 73 to swing left and right. The semi-circular gear 73 drives the air outlet pipe 4 to swing left and right along the circular groove 33, so that the air outlet 41 at the lower end of the air outlet pipe 4 swings left and right. Thus, the air can be blown out along the swinging air outlet 41 left and right, and the air can evenly dissipate heat from the components.

[0037] When the air outlet pipe 4 swings back and forth left and right, the air outlet pipe 4 drives the annular plate 66 to rotate along the fan-shaped groove 65 of the fan-shaped side plate 64.

[0038] When the adjusting mechanism drives the air outlet pipe 4 to move forward, at this time, the air outlet pipe 4 drives the semi-circular gear 73 to move forward, and the semi-circular gear 73 is always not separated from the toothed plate 72.

One end of the transmission plate 92 close to the driving rod 86 is fixedly connected to a shaking plate 9. A shaking groove 91 is formed through the side of the shaking plate 9, and the driving rod 86 is slidably connected to the shaking groove 91. A slot 93 is formed at the top of one end of the transmission plate 92 close to the L-shaped clamping plate 74, and the L-shaped clamping plate 74 is clamped with the slot 93.

[0041] When the partition plate 3 is installed, one end of the transmission plate 92 is in the through groove. At this time, the L-shaped clamping plate 74 is inserted along the through groove. When the transmission plate 92 contacts the L-shaped clamping plate 74, the downward protruding end of the L-shaped clamping plate 74 is clamped into the slot 93, thereby completing the docking of the transmission plate 92 and the L-shaped clamping plate 74.

[0042] The motor shaft of the servo motor drives the driving bevel gear 81 to rotate. The driving bevel gear 81 drives the transmission bevel gear 84 to rotate. The transmission bevel gear 84 drives the circular plate 85 to rotate through the rotating shaft 83. The circular plate 85 drives the driving rod 86 to slide along the shaking groove 91. At the same time, the driving rod 86 drives the shaking plate 9 to move left and right reciprocally. The shaking plate 9 drives the transmission plate 92 to slide left and right reciprocally along the through groove. At the same time, the transmission plate 92 drives the L-shaped clamping plate 74 to slide left and right reciprocally. The L-shaped clamping plate 74 drives the strip plate 7 to slide left and right reciprocally along the strip groove 36.

[0043] Working principle: When the partition plate 3 is assembled with the optical cable cross-connect box body 1, the partition plate 3 is horizontally inserted into the inner cavity of the optical cable cross-connect box body 1. The two guiding grooves 31 on the left and right sides of the partition plate 3 are stuck on the two guide rails 11. The partition plate 3 is inserted backward along the guide rails 11 until the front end of the guide rail 11 abuts against the closed end of the guiding groove 31, and then the partition plate 3 and the guide rail 11 are locked through the locking screw 12; At this time, the rear side of the partition plate 3 contacts the side surface of the air guide duct 21, and at the same time, the docking head 51 of the docking mechanism is inserted into the docking pipe 22, thus completing the installation of the partition plate 3.

[0044] During operation, the wind blows into the air guide duct 21 along the air inlet pipe 2, enters the docking head 51 along the air guide duct 21 and the docking pipe 22, and the wind enters the inner cavity of the connecting pipe 5 along the docking head 51. At this time, the conical plug 55 is separated from the conical groove, and the wind passes through the rotating seat 52 and the rotary joint 42 along the connecting pipe 5 and enters the inner cavity of the air outlet pipe 4. Then the wind blows downward along the air outlet 41 and the fan-shaped opening 34, so as to dissipate heat from the components in the inner cavity of the optical cable cross-connect box body 1.

[0045] At this time, the motor shaft of the servo motor drives the driving bevel gear 81 to rotate, so that the driven bevel gear 84 drives the circular plate 85 to rotate through the rotating shaft 83. The circular plate 85 drives the driving rod 86 to slide along the shaking groove 91. At the same time, the driving rod 86 drives the shaking plate 9 to move left and right reciprocally. The shaking plate 9 drives the L-shaped clamping plate 74 to slide left and right reciprocally through the transmission plate 92. The L-shaped clamping plate 74 drives the strip plate 7 to slide left and right reciprocally along the strip groove 36. The strip plate 7 drives the semi-circular gear 73 to swing left and right through the toothed plate 72. The semi-circular gear 73 drives the air outlet pipe 4 to swing left and right along the circular groove 33, so that the air outlet 41 at the lower end of the air outlet pipe 4 swings left and right, so that the wind can blow out swingingly along the air outlet 41, so that the wind can evenly dissipate heat from the components, and thus greatly improves the heat dissipation effect on the components.

[0046] Through the suction force generated by the negative pressure pump, the heat dissipated by the components and the wind blowing over the components enter the suction main pipe 23 along the suction branch pipe 24. At this time, the wind is sucked away by the negative pressure pump along the suction main pipe 23, the suction pipe and the extension pipe. By using blowing and suction in combination to form an efficient air duct, the components in the optical cable cross-connect box can be efficiently dissipated heat, so that the air inflow is slightly greater than the air exhaust volume, reducing dust accumulation.

[0047] When components are installed below a certain air outlet mechanism, the air outlet pipe 4 is driven to move forward by the adjusting mechanism. The air outlet pipe 4 drives the rotary joint 42 to slowly separate from the rotating seat 52. At this time, the rotary joint 42 drives the push rod 57 to move out of the inner cavity of the connecting pipe 5, so that the push rod 57 releases the push on the conical plug 55. Under the action of the elastic force of the return spring 56, the conical plug 55 seals one end of the connecting pipe 5. At this time, the wind will not enter the rotating seat 52 along the connecting pipe 5, that is, the air outlet 41 in this air outlet mechanism will not blow out downward.

[0048] When the air outlet mechanism needs to blow air, the air outlet pipe 4 is driven to move backward by the adjustment mechanism. The air outlet pipe 4 drives the rotary joint 42 to be slowly inserted into the rotary seat 52. At this time, the rotary joint 42 drives the push rod 57 to be inserted into the inner cavity of the connecting pipe 5, so that the push rod 57 pushes the tapered plug 55 to separate from the tapered groove, and the tapered plug 55 releases the seal of the connecting pipe 5. At this time, the air can enter the rotary seat 52 along the connecting pipe 5, enabling the air outlet 41 of the air outlet mechanism to blow air normally.

[0049] Through the cooperation of the provided adjustment mechanism and the sealing component, it is possible to adjust whether a certain air outlet mechanism can blow air according to the actual situation. When no components are installed below the air outlet mechanism, the air outlet mechanism does not blow air, improving the utilization rate of resources.

[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
