Description

Technical Field

[0001] The invention relates to the technical field of communication engineering, in particular to an optical fiber exchange cabinet used in communication engineering. Background Art

[0002] Communication engineering, also known as telecommunication engineering, formerly known as long-distance communication engineering and weak current engineering, is an important branch of electronic engineering, a sub-major of electronic information, and also one of the basic disciplines. This discipline focuses on the principles and applications of information transmission and signal processing in the communication process. It has knowledge of communication systems and communication networks, and can engage in research, design, manufacturing, operation in the field of communication, and develop and apply communication technology and equipment in various sectors of the national economy and the defense industry. Communication engineering studies the generation of signals, the transmission, exchange and processing of information, as well as the theory and engineering application in computer communications, digital communications, satellite communications, fiber-optic communications, cellular communications, personal communications, stratospheric communications, multimedia technology, information highways, digital program-controlled switching, etc. However, the current fiber-optic switching devices will generate a lot of heat during operation. When the internal heat exceeds the adaptive heat of the working components, it will directly affect the working efficiency and service life of the fiber-optic switching device.

[0003] After searching, it is found that a fiber optic switch cabinet for computer communication engineering proposed in patent publication number CN109327743A includes a switch cabinet, a lower cabinet and an upper cabinet. The bottom of the switch cabinet is provided with a base, and the top of the switch cabinet is supported by a top plate through a support rod. The switch cabinet is divided into a lower cabinet and an upper cabinet, and the upper cabinet is located above the lower cabinet. A first electrical component fixing plate is provided inside the upper cabinet, a mesh layer is provided between the upper cabinet and the lower cabinet, and two sets of fans are installed on the inner top of the upper cabinet.

[0004] The optical fiber switch cabinet in the above patent uses a cooling fan to dissipate the heat inside the cabinet, introduces cold air from the outside, forms an air-cooled circulation system, and realizes efficient heat dissipation of the cabinet. However, in normal use, since the installation position of the cooling fan is relatively fixed, and the temperature of the electronic components in the cabinet is different at different working frequencies, if the cooling fan only blows on the electronic components with low frequency, it will easily cause the temperature inside the entire optical fiber switch cabinet to rise above the above level in the long run, thus having certain limitations. Therefore, there is an urgent need for an optical fiber switch cabinet for communication engineering to solve the above problems. Summary of the invention

When the blow box is located on the right side of the cabinet, a large amount of gas is blown out to the switch or gas storage element, ensuring that the dust removal and heat dissipation effect is achieved without damaging the installation stability, while the amount of gas blown out at the power supply is less (because the existing power supply technology is becoming mature and generally comes with a set of fans. If the amount of gas blown out is too large at this time, it will produce The convection or lateral airflow generated will affect the speed of the fan inside the power supply, thereby reducing its own heat dissipation effect). At the same time, the small amount of gas blown out can also remove dust from the surface of the power supply and electrical components to a certain extent, avoiding the accumulation of dust and affecting heat dissipation, thereby improving the practicality of the entire device; as the blowing box reciprocates on the side wall of the reciprocating threaded groove rod, high and low pressure chambers can be formed on both sides of the cabinet, and the pressure difference generates an airflow from right to left, realizing full circulation of the airflow inside the cabinet, thereby further improving the gas circulation between the components inside the entire cabinet and avoiding overheating.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-Figure 9 The present invention provides a technical solution of an optical fiber exchange cabinet for communication engineering: an optical fiber exchange cabinet for communication engineering, comprising a cabinet 1, and a side panel 2 detachably mounted on the side wall of the cabinet 1, a mainboard 3 and a hard disk mounting seat 4 are fixedly mounted on the rear side wall of the cabinet 1, a power supply box 5 is fixedly mounted on the left side wall of the cabinet 1, and further comprising:

[0042] A support base 6, the support base 6 is fixedly connected to the left and right sides of the top surface of the inner cavity of the cabinet 1;

[0043] The temperature control mechanism 7 is arranged on the right side of the top surface of the inner cavity of the cabinet 1, and the temperature control mechanism 7 is used to monitor the ambient temperature inside the cabinet 1;

[0044] A heat dissipation mechanism 8, which is disposed between the support seats 6 on both sides and is used to improve the heat dissipation of the cabinet 1 under overclocking operation;

[0045] The dust removal mechanism 9 is arranged between the support seats 6 on both sides, and the dust removal mechanism 9 is used to remove dust from components such as the switch in the cabinet 1.

[0046] Furthermore, the temperature control mechanism 7 includes a temperature-isolating box 71 fixedly connected to the right side of the top surface of the inner cavity of the cabinet 1, the inner cavity of the temperature-isolating box 71 is slidably connected to a slide-out seat 72, and the rear end surface of the slide-out seat 72 is fixedly connected to a contact plate 74;

[0047] The upper end surface of the slide-out seat 72 is fixedly connected with a return spring 73, and the other end of the return spring 73 is fixedly connected to the top surface of the inner cavity of the thermal insulation box 71. The slide-out seat 72 is hollow, and the top surface of the inner cavity of the slide-out seat 72 is fixedly connected with a heat-conducting block, which is used to introduce heat into the upper inner cavity of the thermal insulation box 71.

[0048] It should be noted that when the fiber optic switch cabinet is working in an overclocked state, the temperature inside the cabinet 1 will increase significantly. At this time, the high temperature of the environment will be transferred to the upper inner cavity of the insulation box 71 through the heat conduction block arranged on the top surface of the slide-out seat 72. As the air pressure in the upper inner cavity of the insulation box 71 increases, the gas expands. At this time, the pressure of the gas can stretch the reset spring 73, and finally the slide-out seat 72 will drive the contact plate 74 to move downward and against the piezoelectric switch 75. At this time, the servo motor 81 is started, thereby driving the front bidirectional threaded groove rod 82 to rotate. Since the cooling fan 83 is fixedly connected to the bidirectional threaded groove rod 82, the cooling fan 83 also rotates accordingly. At this time, under the position constraint limit of the two reciprocating threaded groove rods 82, the blowing box 93 will reciprocate left and right on the side wall of the reciprocating threaded groove rod 82, that is, the reciprocating threaded groove rod 82 on the rear side will also drive the cooling fan 83 to rotate accordingly. By adding two groups of cooling fans 83, the cooling effect of the entire device can be enhanced.

[0049] Furthermore, the heat dissipation mechanism 8 includes a reciprocating threaded groove rod 82 rotatably connected between the two side support seats 6, a heat dissipation fan 83 is fixedly connected to the left side of each reciprocating threaded groove rod 82, and an air guide cover 84 is fixedly connected to the upper left end surface of the cabinet 1;

[0050] The inner cavity of the air guide cover 84 is provided with a dust collection groove, which is used to collect dust inside the cabinet 1, so as to facilitate the user to uniformly handle it later;

[0051] A servo motor 81 is fixedly connected to the right end face of the support seat 6 located on the right side. The output shaft end of the servo motor 81 passes through the support seat 6 and is fixedly connected to the reciprocating threaded groove rod 82 on the front side. A piezoelectric switch 75 is provided on the servo motor 81, and the servo motor 81 is electrically connected to the power supply through a power cord.

[0052] It should be noted that when the blow box 93 moves from right to left, (such as Fig. 9As shown in the figure, due to the setting of the one-way air valves in two directions on both sides of the air inlet and the air outlet, the rated wind force blown out is the same, but there is a difference. When the blow box 93 is located on the right side, the air outlet time is longer, so that the air flow on the right side of the cabinet 1 is faster and the air pressure is stronger. When the blow box 93 is located on the left side, the air outlet time is shorter, and the air flow on the left side of the cabinet 1 is slower and the air pressure is stronger. Through the pressure difference of the air on both sides, an airflow from right to left will be generated. Combined with the blowing of the fan of the cabinet 1 itself, the air flow inside the cabinet 1 can be fully circulated, further improving the gas circulation between the various components inside the entire cabinet 1.

[0053] Furthermore, the dust removal mechanism 9 includes a screw rod 91 fixedly connected to the upper part of the support seats 6 on both sides, a cam 92 is threadedly connected to the middle part of the outer wall of the screw rod 91, a blow box 93 is slidably connected to the middle part of the outer wall of the reciprocating thread groove rod 82, a limit rod 821 is slidably connected to the inner cavity of the thread groove wall of the reciprocating thread groove rod 82, and a friction member 94 is fixedly connected to the front and rear sides of the upper end face of the blow box 93;

[0054] The thread lead angle of the screw rod 91 is greater than the equivalent friction angle of the cam 92. The inner walls of the support seat 6 on both sides are provided with a slide groove 61. The bottom surface of the slide groove 61 is fixedly connected with a compression spring 62. The other end of the compression spring 62 is fixedly connected with a conical column 63.

[0055] The conical column 63 slides in the inner cavity of the slide groove 61, the cam 92 fits the side wall of the conical column 63, the limit rod 821 is fixedly connected to the blow box 93, and the friction member 94 is slidably connected to the cam 92;

[0056] The inner cavity of the blowing box 93 is slidably connected with a compression plate 931, the upper end surface of the compression plate 931 is fixedly connected with a sliding column 932, the sliding column 932 is slidably connected with the conical column 63, the lower end surface of the blowing box 93 is provided with an air outlet, and the outlet of the air outlet is provided with a one-way air valve that opens to the outside of the blowing box 93, the left and right side walls of the blowing box 93 are provided with air inlets, and the entrance of the air inlet is provided with a one-way air valve that opens to the inside of the blowing box 93.

[0057] It should be noted that when the blow box 93 moves back and forth on the side wall of the reciprocating thread groove rod 82, under the constraint of the friction member 94 and the screw rod 91, the cam 92 will also move back and forth and rotate itself. Since the side wall of the cam 92 is always in contact with the side wall of the tapered column 63, the tapered column 63 will also drive the sliding column 932 to make the compression plate 931 slide back and forth in the inner cavity of the blow box 93 as the cam 92 rotates. When the inner cavity of the blow box 93 slides back and forth up and down, under the action of the one-way air valves in two directions on both sides of the air inlet and the air outlet, the blow box 93 can continuously receive and squeeze the gas and spray it out from the air outlet to achieve the function of removing dust from the surface of components such as storage hard disks. Due to the special conical shape of the tapered column 63, when the blow box 93 is at different positions on the side wall of the reciprocating thread groove rod 82, the range of the compression plate 931 moving up and down in the inner cavity of the blow box 93 will also be different (such as Figure 8 As shown), when the blow box 93 is at the rightmost side of the reciprocating threaded groove rod 82, the amount of gas blown out to the switch or memory element is relatively large, thereby ensuring good heat dissipation and dust removal effects without damaging the stability of its installation, while the amount of gas blown out at the power supply is relatively small, and at the same time, the small amount of gas blown out can also have a certain degree of dust removal effect on the surface of the power supply, so that the entire device can now realize the function of adaptive dust removal for different components, thereby improving the practicability of the entire device.

[0058] Working principle:

[0059] When the fiber optic switch cabinet is working in an overclocked state, the temperature in the cabinet 1 will increase significantly. At this time, the high temperature of the environment will be transferred to the upper inner cavity of the insulation box 71 through the heat conduction block arranged on the top surface of the slide-out seat 72. As the air pressure in the upper inner cavity of the insulation box 71 increases, the gas expands. At this time, the pressure of the gas can stretch the reset spring 73, and finally the slide-out seat 72 will drive the contact plate 74 to move downward and against the piezoelectric switch 75. At this time, the servo motor 81 is started, thereby driving the bidirectional threaded groove rod 82 on the front side to rotate. Since the cooling fan 83 is fixedly connected to the bidirectional threaded groove rod 82, the cooling fan 83 also rotates accordingly. At this time, at the position of the two reciprocating threaded groove rods 82 Under the constraint limit, the blowing box 93 will reciprocate left and right on the side wall of the reciprocating threaded groove rod 82, that is, the reciprocating threaded groove rod 82 on the rear side will also drive the cooling fan 83 to rotate accordingly. By adding two sets of cooling fans 83, the cooling effect of the entire device will also be enhanced, and the heat dissipation can be adaptively adjusted according to different working temperatures in the cabinet. At the same time, the cooling fan 83 drives the airflow flowing toward the rear of the cabinet 1 to make the dust scattered in the cabinet 1 pass through the air guide cover 84. Through the setting of the dust accumulation groove, part of the dust can be retained in the dust accumulation groove, so as to facilitate the uniform collection of dust by workers, ensure the cleanliness of the interior of the cabinet 1, and thus improve the service life of components such as hard disks stored in the cabinet 1;

[0060] When the blow box 93 moves back and forth on the side wall of the reciprocating thread groove rod 82, under the constraint of the friction member 94 and the screw rod 91, the cam 92 will also move back and forth and rotate itself at the same time. Since the side wall of the cam 92 is always in contact with the side wall of the tapered column 63, the tapered column 63 will also drive the sliding column 932 to make the compression plate 931 slide back and forth in the inner cavity of the blow box 93 as the cam 92 rotates. When the compression plate 931 slides back and forth in the inner cavity of the blow box 93, under the action of the one-way air valves in two directions on both sides of the air inlet and the air outlet, the blow box 93 can continuously receive the squeezed gas and spray it from the air outlet, so as to realize the function of removing dust on the surface of components such as storage hard disks.

[0061] Due to the special conical shape of the conical column 63, when the blow box 93 is at different positions on the side wall of the reciprocating thread groove rod 82, the range of movement of the compression plate 931 in the inner cavity of the blow box 93 will also be different (such as Figure 8As shown), when the blow box 93 is at the rightmost side of the reciprocating threaded groove rod 82, the amount of gas blown out to the switch or memory element is relatively large, ensuring its good heat dissipation and dust removal effect without damaging its installation stability, while the amount of gas blown out at the power supply is relatively small (because the existing power supply technology is becoming mature, and generally comes with a set of fans. If the amount of gas blown out is too large at this time, the convection or lateral airflow generated will affect the speed of the fan inside the power supply, thereby reducing its own heat dissipation effect). At the same time, the small amount of gas blown out can also have a certain degree of dust removal effect on the surface of the power supply, so that the entire device can realize the function of adaptive dust removal for different components at this time, thereby improving the practicality of the entire device;

[0062] It should be noted that when the blow box 93 moves from right to left, (such as Fig. 9 As shown) Due to the setting of the one-way air valves in two directions on both sides of the air inlet and the air outlet, the rated wind force blown out is the same, but there is a difference. When the blow box 93 is located on the right side, the air outlet time is longer, so that the air flow on the right side of the cabinet 1 is faster and the air pressure is stronger. When the blow box 93 is located on the left side, the air outlet time is shorter, and the air flow on the left side of the cabinet 1 is slower and the air pressure is stronger. Through the pressure difference of the air on both sides, an airflow from right to left will be generated. Combined with the blowing of the fan of the cabinet 1 itself, the air flow inside the cabinet 1 can be fully circulated, and the gas circulation between the components inside the entire cabinet 1 can be further improved to avoid overheating (it should be noted that when the blow box 93 moves from left to right, the reverse airflow formed is not enough to offset the airflow generated by the cooling fan of the cabinet 1 itself, and will not affect the heat dissipation effect inside the cabinet 1).

[0063] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
