Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, in particular to a safety power distribution cabinet with a monitoring function. Background Art

[0002] The distribution cabinet is an electrical device used for control, distribution, protection and monitoring. It can integrate and protect electrical equipment and electronic components. It mainly protects electrical equipment and ensures the reliable and stable operation of the power system. Most outdoor distribution cabinets mainly protect the internal electrical equipment and electronic components through the cabinet body. The distribution cabinet can monitor the internal electronic components in conjunction with monitoring equipment to avoid affecting normal operation due to high temperature and other conditions.

[0003] The utility model with announcement number CN218919675U discloses a safe distribution cabinet with monitoring function. The distribution switches in the cabinet cavity can be monitored by video through an industrial camera. The monitoring signal is transmitted to a monitor, and the monitoring screen can be displayed through the monitor. The safety of the distribution cabinet during use can be improved, and there is no need to open the cabinet door frequently. By driving the industrial camera to rise and fall in the cabinet, the monitoring range of the industrial camera can be expanded. Only one industrial camera is needed to monitor the cabinet cavity in all aspects.

[0004] The invention with announcement number CN117833046A discloses a distribution cabinet with a distribution cabinet monitoring terminal, wherein sealing rings are installed inside the mounting holes, an insulating shell is fixed inside the cabinet, a controller is installed on the inner wall of the insulating shell near the top, an annular sealing gasket is arranged inside the insulating shell near the exit, and two symmetrical electric push rods are installed on the rear surface of the cabinet door. By setting a protective mechanism, the emergency protection capability of the distribution cabinet can be improved, thereby improving the use effect of the distribution cabinet, that is, improving the use efficiency of the distribution cabinet.

[0005] However, the above-disclosed distribution cabinet with a monitoring mechanism still has the following problems during actual use: although a monitoring device is arranged inside the distribution cabinet to monitor the status of the internal electronic components in real time, monitoring alone cannot assist the electronic components to work better. During the heating process of the electronic components, the required heat dissipation mechanism needs to be equipped, and when the heat dissipation mechanism is running, the dust inhaled from the outside can easily block the heat dissipation area, thereby causing the heat to be unable to be exchanged, affecting the normal operation of the distribution cabinet.

[0006] Therefore, we propose a safe distribution cabinet with monitoring function to solve the above problems. Summary of the invention

[0010] Preferably, the dust removal mechanism includes a dust removal spray nozzle, and the dust removal spray nozzle is fixedly installed on the left and right sides of the bottom surface of the distribution cabinet body, and the symmetrically arranged dust removal spray nozzle is through-connected with the elastic airbag, and the symmetrically arranged dust removal spray nozzle is directly opposite to the bottom surface of the dust removal brush plate.

[0011] Preferably, the heat dissipation mechanism includes a driving shaft, and the driving shaft is rotatably arranged at the inner center position of the heat dissipation baffle through a bearing, and heat dissipation fan blades are fixedly arranged on the lower outer wall of the driving shaft, and the top end of the driving shaft is fixedly connected to the inner end of the elastic steel cable at an equal angle.

[0012] Preferably, the heat dissipation mechanism includes a heat dissipation ring groove, and the heat dissipation ring groove is opened inside the upper part of the heat dissipation baffle, and a guide slider is provided inside the heat dissipation ring groove for sliding at an equal angle, and the top end of the guide slider elastically slides inside the sealing arc plate.

[0013] Preferably, the top surface of the sealing arc plate included in the heat dissipation mechanism is fixedly connected to the outer end of the elastic steel cable, and the multiple sealing arc plates in the initial state form a complete circular structure, and the elastic steel cable is driven to rotate by the driving shaft included in the heat dissipation mechanism, so that the guide slider and the sealing arc plate follow the rotation in the heat dissipation ring groove.

[0014] Preferably, the rotating sealing arc plates are driven by centrifugal force to slide outward, so that the sealing arc plates arranged at equal angles are in an open state, thereby allowing external air to enter the upper interior of the distribution cabinet body through the heat dissipation mechanism.

[0015] Preferably, a monitoring mechanism is arranged on the upper part of the interior of the distribution cabinet body, and the monitoring mechanism includes a reciprocating threaded rod, and the rotation of the reciprocating threaded rod is arranged on the left and right sides of the interior of the distribution cabinet body, and the top ends of the symmetrically arranged reciprocating threaded rods are meshed and connected through a sprocket mechanism, and at the same time, the outer wall of the reciprocating threaded rod is threadedly connected to a bearing platform.

[0016] Preferably, a transmission shaft is arranged on the outer side of the top surface of the bearing platform included in the monitoring mechanism through a torsion spring, and the outer end of the transmission shaft and the reciprocating threaded rod are meshed with each other through an incomplete bevel gear group, and the reciprocating threaded rod and the incomplete bevel gear group are connected by sliding and rotating through a concave-convex fit.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the safe distribution cabinet with monitoring function can efficiently monitor the electronic components through the monitoring probe that can reciprocate and rise and fall inside the distribution cabinet, and the heat of the electronic components drives the air inlet grille to open, so that the sealing arc plate and the heat dissipation baffle can be opened by centrifugal force when the heat dissipation mechanism is working, and then the negative pressure is generated to enter the air to achieve heat dissipation, so as to improve the stability of the operation of the distribution cabinet body. The specific contents are as follows: 1. The heat dissipated by the electronic components can be transferred to the thermal copper sheet and transported to the air inside the elastic airbag to expand due to the heat. After the volume of the elastic airbag increases, it slides upward against the dust removal brush plate attached to the top, so that the dust removal brush plate can open the previously blocked air inlet grille, allowing air from outside the distribution cabinet body to enter, assisting the subsequent heat dissipation mechanism to exchange heat.

[0019] After the heat dissipation is completed, the elastic airbag returns to its original state, and the dust removal brush plate on the top of the elastic airbag slides downward after no longer interfering with it, and cleans and seals the air inlet grilles on the left and right sides to prevent external dust and dirt from entering the interior of the distribution cabinet body and affecting the working environment of electronic components.

[0020] 2. The driving shaft is driven by the driving motor at the bottom to rotate slowly, so that the driving shaft drives the external cooling fan blades to rotate, so that the cooling fan blades introduce air into the lower part of the distribution cabinet body through the opened air inlet grille in a negative pressure manner to perform heat dissipation.

[0021] The driving shaft drives the sealing arc plate through the elastic steel cable so that it rotates along the heat dissipation ring groove opened inside the heat dissipation baffle. The sealing arc plate slides outward through centrifugal force, so that the sealing arc plates at equal angles move away from each other to open the heat dissipation baffle, so that the external air enters the upper part of the distribution cabinet body after being filtered by the air inlet grille, so as to exchange heat with the electronic components and assist in heat dissipation.

[0022] 3. The rotating reciprocating threaded rod drives the transmission shaft to rotate through the incomplete bevel gear set. The traction cable is wound and loosened during the engagement and disengagement process so that the intermittent rack can move left and right, thereby driving the meshing drive gear and the monitoring probe to rotate back and forth, thereby improving the monitoring effect on electronic components.

[0025] 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 implementation regulations described 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.

[0026] See also Figure 1-Figure 13 , the present invention provides the following technical solutions: Embodiment 1: In order to solve the problems existing in the actual use of the existing distribution cabinet body 1, this embodiment adopts the following technical scheme: a safe distribution cabinet with a monitoring function, comprising a distribution cabinet body 1, and a security door body 2 hingedly installed on the front of the distribution cabinet body 1; air inlet grilles 3 are provided on the left and right sides of the outside below the distribution cabinet body 1; a dust removal mechanism is provided below the distribution cabinet body 1, and the dust removal mechanism includes a dust removal brush plate 4, and the dust removal brush plate 4 is slidably arranged on the left and right sides of the bottom of the distribution cabinet body 1, and the dust removal brush plate 4 slides in contact with the outside of the air inlet grille 3.

[0027] The dust removal mechanism includes an elastic airbag 7, and the elastic airbag 7 is fixedly installed at the lower back of the distribution cabinet body 1, and the dust removal mechanism includes a thermal conductive copper sheet 8, and the thermal conductive copper sheet 8 is fixedly installed at the upper inside of the distribution cabinet body 1, and the thermal conductive copper sheet 8 and the elastic airbag 7 are connected to each other; the dust removal mechanism includes a dust removal spray nozzle 9, and the dust removal spray nozzle 9 is fixedly installed on the left and right sides of the bottom surface of the distribution cabinet body 1, and the symmetrically arranged dust removal spray nozzle 9 is through-connected with the elastic airbag 7, and the symmetrically arranged dust removal spray nozzle 9 is directly opposite to the bottom surface of the dust removal brush plate 4.

[0028] like Figure 2-Figure 3 , Figure 5 As shown, the interior of the distribution cabinet body 1 is installed with protection for various electronic components. At the same time, the heat-conducting copper sheet 8 arranged at the rear of the distribution cabinet body 1 is located behind the electronic components, so that the heat generated by the electronic components during operation can be quickly transferred to the inside of the heat-conducting copper sheet 8, and the heat-conducting copper sheet 8 transfers the heat to the air inside the elastic airbag 7 and causes it to expand due to the heat. At this time, the elastic airbag 7 becomes larger in volume and slides upward against the dust removal brush plate 4 attached to the top, so that the dust removal brush plate 4 opens the previously blocked air inlet grille 3, so that the air outside the distribution cabinet body 1 can enter, assisting the subsequent heat dissipation mechanism to exchange heat.

[0029] Furthermore, after the heat dissipation inside the distribution cabinet body 1 is completed, the elastic airbag 7 returns to its original state, and the dust removal brush plate 4 on the top of the elastic airbag 7 slides downward after no longer being interfered with, and the air inlet grilles 3 on the left and right sides are cleaned and sealed to prevent external dust and dirt from entering the interior of the distribution cabinet body 1 and affecting the working environment of the electronic components.

[0030] Embodiment 2: In order to solve the problems existing in the actual use of the existing distribution cabinet body 1, this embodiment adopts the following technical scheme: a heat dissipation mechanism is arranged at the lower part of the interior of the distribution cabinet body 1, and the heat dissipation mechanism includes a heat dissipation baffle 5, and the heat dissipation baffle 5 is fixedly installed at the lower part of the interior of the distribution cabinet body 1, and a sealing arc plate 6 is slidably arranged at an equal angle on the top surface of the heat dissipation baffle 5; the heat dissipation mechanism includes a driving shaft 10, and the driving shaft 10 is rotatably arranged at the inner center position of the heat dissipation baffle 5 through a bearing, and a heat dissipation fan blade 11 is fixedly arranged on the lower outer wall of the driving shaft 10, and the top end of the driving shaft 10 is fixedly connected to the inner end of the elastic steel cable 12 at an equal angle.

[0032] like Figure 3-Figure 4 , Figure 6-Figure 10As shown, when the power distribution cabinet body 1 performs heat dissipation work, the driving shaft 10 included in the heat dissipation mechanism is driven by the driving motor at its bottom to rotate slowly, so that the driving shaft 10 drives the external heat dissipation fan blades 11 to rotate, so that the heat dissipation fan blades 11 introduce air into the lower part of the power distribution cabinet body 1 through the opened air inlet grille 3 in a negative pressure manner to perform heat dissipation work.

[0033] At the same time, the rotating driving shaft 10 drives the elastic steel cable 12 at the outer end to drive the fixedly connected sealing arc plate 6, so that the sealing arc plate 6 drives the internally slidably connected guide slider 14 to rotate along the heat dissipation ring groove 13 opened inside the heat dissipation baffle 5. At the same time, during the rotation process, the sealing arc plate 6 slides outward by centrifugal force and is limited and stretched by the elastic steel cable 12, so that the sealing arc plates 6 at equal angles move away from each other to open the heat dissipation baffle 5, so that the external air enters the upper part of the distribution cabinet body 1 after being filtered by the air inlet grille 3, so as to exchange heat with the electronic components and assist in heat dissipation.

[0034] Embodiment 3: In order to solve the problems existing in the actual use of the existing distribution cabinet body 1, this embodiment adopts the following technical scheme: a monitoring mechanism is arranged on the upper part of the interior of the distribution cabinet body 1, and the monitoring mechanism includes a reciprocating threaded rod 16, and the rotation of the reciprocating threaded rod 16 is arranged on the left and right sides of the interior of the distribution cabinet body 1, and the top ends of the symmetrically arranged reciprocating threaded rods 16 are meshed and connected through a sprocket mechanism 17, and at the same time, the outer wall of the reciprocating threaded rod 16 is threadedly connected to a bearing platform 18; a transmission shaft 19 is arranged on the outer side of the top surface of the bearing platform 18 included in the monitoring mechanism through a torsion spring rotation, and the outer end of the transmission shaft 19 is meshed with the reciprocating threaded rod 16 through an incomplete bevel gear group 20, and the reciprocating threaded rod 16 and the incomplete bevel gear group 20 are connected by sliding and rotating through a concave-convex fit.

[0035] The monitoring mechanism includes a monitoring probe 21, and the monitoring probe 21 is rotatably arranged on the top surface of the supporting platform 18 at equal distances through bearings, and a driving gear 22 is fixedly arranged on the bottom end of the monitoring probe 21, and an intermittent rack 23 meshing with the driving gear 22 is elastically slidably arranged on the bottom surface of the supporting platform 18, and a traction steel cable 15 is fixedly connected to the outer side of the intermittent rack 23, and the outer end of the traction steel cable 15 is wound around the outer wall of the transmission shaft 19.

[0036] like Figure 1 , Figure 11-13 As shown, the driving motor installed inside the distribution cabinet body 1 drives the reciprocating threaded rod 16 connected to the sprocket mechanism 17 to rotate, and then the reciprocating threaded rod 16 drives the supporting platform 18 to reciprocate in the up and down directions, so as to increase the monitoring range of the monitoring probes 21 arranged at equal distances on the top surface of the supporting platform 18.

[0037] At the same time, the reciprocating threaded rod 16 drives the transmission shaft 19 to rotate through the incomplete bevel gear group 20 matched with the external concave-convex structure. At the same time, the transmission shaft 19 drives the intermittent rack 23 on the bottom surface to move after winding the traction cable 15, so as to engage the drive gear 22 and the monitoring probe 21 to rotate. At the same time, when the incomplete bevel gear group 20 is not engaged, the elastically arranged transmission shaft 19 loosens the traction cable 15, so that the elastically connected intermittent rack 23 drives the drive gear 22 to rotate and reset, so that the monitoring probe 21 can realize monitoring in another direction after rotating in the opposite direction, thereby improving the monitoring effect on electronic components.
