Description

Technical Field

[0001] The invention belongs to the technical field of power distribution cabinets, and in particular relates to a rainproof and heat-dissipating power distribution cabinet. Background Art

[0002] The power distribution cabinet is the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits. They distribute the power of a circuit of the upper-level power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. Since there are many circuits inside the power distribution cabinet, a large amount of heat will be generated during use. In order to avoid the safety accidents of the power distribution cabinet spontaneous combustion or even explosion due to excessive temperature, heat dissipation holes are usually set at the bottom of both sides of the cabinet. At the same time, in order to prevent the fallen leaves, plastic bags, etc. in the environment from entering the cabinet in windy weather when the outdoor power distribution cabinet is in use, in the existing related technologies, the heat dissipation holes are set as shutter-type structures or filters are set at the heat dissipation holes to prevent the fallen leaves, plastic bags, etc. from entering the cabinet in windy weather.

[0003] However, by providing a shutter structure or a filter at the heat dissipation holes, the heat dissipation holes can be sealed, so that in windy and rainy weather, raindrops in the environment will enter the inside of the cabinet with the action of wind. The raindrops entering the cabinet will not only easily increase the humidity in the cabinet, but also easily cause the metal of the electrical components in the cabinet to rust, and also easily cause some electrical components in the cabinet to get damp, resulting in short circuits and even fires.

DETAILED DESCRIPTION

[0019] 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.

[0020] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0021] See also Figure 1-7As shown, the present invention provides a rainproof and heat-dissipating power distribution cabinet, which can not only achieve heat dissipation and ventilation when in use, but also prevent rainwater from entering the inside of the power distribution cabinet body 1 when in use; the power distribution cabinet of the present invention comprises a power distribution cabinet body 1, and rectangular openings A10 are respectively provided on the two side panels of the power distribution cabinet body 1, and a rectangular frame 12 is provided on the outer side wall of the side panel at the rectangular opening A10, the inner bottom side surface of the rectangular frame 12 is lower than the bottom end surface of the rectangular opening A10, and a cover plate 13 is provided on the outer side wall of the rectangular frame 12, and a rectangular opening B is provided at the bottom of the cover plate 13 facing the rectangular opening 10, and a filter screen 14 is provided at the rectangular opening B, and the filter screen 14 is provided to protect the rectangular opening B for heat dissipation by using the setting of the filter screen 14, so as to prevent garbage such as fallen leaves in the environment that are easily blown out by strong wind from entering the inside of the power distribution cabinet body 1 through the rectangular opening B; At the same time, in order to prevent rainwater from entering the inside of the distribution cabinet body 1 during use, the present invention is provided with multiple sets of guide slots 16 on both sides of the rectangular frame 12, and the guide slots 16 are cooperated with rain shields 4 and rain shield mesh plates 3 that move up and down along the length direction of the guide slots 16. When in use, when it rains, by controlling the rain shield mesh plates 3 to fall, not only can part of the rainwater be prevented from entering the inside of the distribution cabinet body 1, but also because the rain shield mesh plates 3 have ventilation performance, the distribution cabinet can dissipate heat through the rain shield mesh plates 3, the rectangular opening A and the rectangular opening B; when it rains, when environmental rainwater enters the inside of the rectangular frame 12 through the filter screen 14, it is first blocked by the rain shield mesh plates 3. When it is determined that the rain shield mesh plates 3 cannot completely block the environmental rainwater, the rain shield plates 4 are controlled to fall, and the fallen rain shield plates 4 are used to block the rainwater entering the inside of the rectangular frame 12, so as to prevent rainwater from entering the inside of the distribution cabinet body 1 through the rectangular opening A10.

[0022] Specifically, in order to facilitate the discharge of rainwater entering the rectangular frame 12, a plurality of drainage holes 15 are provided at the bottom of the rectangular frame 12; at the same time, in order to facilitate the control of the rain shield 4 falling down according to needs during use, a detection mechanism A is provided on the rain shield mesh plate 3 to detect whether external rainwater enters the distribution cabinet body 1, and a control mechanism for controlling the up and down movements of the rain shield 4 and the rain shield mesh plate 3 is provided.

[0023] Based on the above, during use, when the raindrop sensor arranged on the top of the distribution cabinet body 1 detects rain, the rain shield mesh plate 3 is first controlled by the control mechanism to move downward to form a preliminary rain shield; then the detection mechanism A arranged on the rain shield mesh plate 3 is used for detection. When it is judged that a large amount of rainwater will pass through the rain shield mesh plate 3 and enter the interior of the distribution cabinet body 1, the rain shield mesh plate 3 is moved downward again through the control mechanism.

[0024] It can be known that in order to facilitate the use of the detection mechanism A for detection, in a specific manner that can be implemented, such as Figure 8-9 The detection mechanism A provided by the present invention includes a plurality of bell mouths 31 arranged on one side of the rain shield mesh plate 3, the narrow end of the bell mouth 31 is connected with a vertical drain pipe A32, the bottom ends of the plurality of drain pipes A32 are connected with a horizontal detection tube 33, one side of the detection tube 33 is connected with a drain pipe B34, and a liquid level sensor is arranged in the drain pipe B34; the wide end of the bell mouth 31 is directly opposite to one side of the filter screen 14; and a drain valve is arranged at the bottom end of the drain pipe B34; through the arrangement of the bell mouth 31, part of the rainwater entering the rectangular frame 12 area through the filter screen 14 is collected when in use, and the collected rainwater is gathered through the drain pipe A32, and then gathered again through the detection tube 33 and flows into the drain pipe B34 for collection; when it is determined that the total amount of collected rainwater reaches the preset value, it is determined that the rain shield 4 needs to be controlled to fall; then the drain valve arranged at the bottom end of the drain pipe B34 is controlled to discharge the rainwater stored in the drain pipe B34.

[0025] Specifically, in order to prevent rainwater entering the rectangular frame 12 from overflowing into the distribution cabinet body 1 during use, an upwardly protruding water retaining edge 11 is provided on the bottom side of the rectangular frame 12 located between the drainage hole 15 and the rectangular opening A10; and the rain shield mesh plate 3 is located between the rain shield plate 4 and the filter screen 14; and the rain shield mesh plate 3 and the rain shield plate 4 are both located between the water retaining edge 11 and the filter screen 14.

[0026] At the same time, during use, with long-term use, garbage such as fallen leaves floating in the air and dust will adhere to the filter 14. If they are not cleaned for a long time, it will affect the ventilation performance of the filter 14. During use, in order to facilitate the cleaning of dust and the like attached to the filter 14, a filter cleaning structure 2 that can move up and down along the length direction of the guide slot 16 is provided between the cover plate 13 and the rain shield mesh plate 3. When cleaning, the filter cleaning structure 2 is controlled to move up and down along the length direction of the guide slot 16, and then the filter 14 is cleaned by the filter cleaning structure 2.

[0027] It can be known that in order to conveniently control the filter cleaning structure 2, the rain screen plate 3 and the rain screen plate 4 to move up and down along the length direction of the guide chute 16 during use, the present invention provides the following two methods: Method 1: The control mechanism includes three sets of multi-section telescopic cylinders vertically installed on the inner top side of the rectangular frame 12, and the ends of the multi-section telescopic cylinders are connected to the top of the filter cleaning structure 2, the rain shield mesh plate 3 and the rain shield plate 4. When in use, the movement of the multi-section telescopic cylinders is controlled to control the filter cleaning structure 2, the rain shield mesh plate 3 and the rain shield plate 4 to move up and down as needed.

[0028] Method 2, the control mechanism includes three sets of linear modules installed on the two vertical side walls of the rectangular frame 12, and the slider of the linear module is connected to one side of the filter cleaning structure 2, the rain shield mesh plate 3 or the rain shield plate 4 through an L-shaped connecting frame, that is, when in use, the movement of the slider on the linear module drives the filter cleaning structure 2, the rain shield mesh plate 3 or the rain shield plate 4 to move up and down as needed.

[0029] Method 3: If Figure 4-5 The control mechanism includes a rotating shaft 72 installed between the front plate and the back plate of the distribution cabinet body 1, a gear A71 is arranged on the rotating shaft 72, a motor 7 is arranged on the inner wall of the distribution cabinet body 1 located on one side of the rotating shaft 72, and a gear B702 meshing with the gear A71 is installed at the output end of the motor 7; two winding reel groups are installed on the rotating shaft 72, and the winding reel group includes a winding reel A73, a winding reel B75 and a winding reel C74 installed on the rotating shaft 72, and the winding reel A73 and the winding reel B75 are respectively fixed with a traction rope A40 and a traction rope B30, and the ends of the traction rope A40 and the traction rope B30 are respectively connected to the top of the rain shield 4 and the rain shield mesh plate 3; and the winding reel C74 includes A disk body 740 is in the shape of an "I" character; a traction rope C20 is connected between the tops of the two filter cleaning structures 2, and the traction rope C20 passes through one side of the winding disk C74; a first component and a second component that cooperate with each other are respectively arranged between the opposite side walls of the disk body 740 to form a blocking rod. When in use, when the first component and the second component are extended and docked, the traction rope C20 passes through the channel formed by the winding disk C74 and the blocking rod. At this time, when the control motor 7 drives the winding disk C74 to rotate, the winding disk C74 rotates and drives the traction rope C20 to be wound around the winding disk C74; in a natural state, the filter cleaning structure 2 is at the bottom of the rectangular frame 12.

[0030] On the basis of the above, if Figure 10-11 The first component and the second component provided by the present invention both include a conical platform 741 respectively arranged on the two inner side walls of the disk body 740, and an installation cavity 742 is arranged at the bottom end of the conical platform 741, and a telescopic motor 743 is installed in the installation cavity 742, and a penetrating sliding cavity 744 is arranged in the conical platform 741, and active columns A745 and active columns B746 that slide along their axial directions are arranged in the two sliding cavities 744, and mutually matching slots 747 and plug columns 748 are arranged at the opposite ends of the active columns A745 and B746; at the same time, the output end of the telescopic motor 743 is magnetically connected to the active columns A745 and B746.

[0031] Specifically, in a specific embodiment, the filter cleaning structure 2 provided by the present invention includes a rectangular rod 21 with both ends respectively stuck in the guide slide groove 16, and a cleaning brush 22 is provided on one side of the rectangular rod 21. At this time, the two ends of the traction rope C20 are respectively connected to one side of the rectangular rod 21, and then when in use, the traction rope C20 is driven by the rotation of the winding drum C74 to drive the winding drum C74, or released from the winding drum C74, so that it is convenient to control the rectangular rod 21 to move up and down along the length direction of the guide slide groove 16.

[0032] It can be known that, in the process of controlling the up and down movement of the rain shielding mesh plate 3 and the rain shielding plate 4, only when the rain shielding mesh plate 3 is in a completely falling state, the rain shielding plate 4 can be controlled to fall; and only when the rain shielding plate 4 is in a raised state, the rain shielding mesh plate 3 can be controlled to rise. The present invention provides a limiting mechanism on both side walls of the rectangular frame 12 located between the rain shielding mesh plate 3 and the rain shielding plate 4; Figure 7 The limiting mechanism includes a fixed shaft 171 fixed on the side wall of the rectangular frame 12, and a limiting plate 17 is rotatably mounted on the fixed shaft 171.

[0033] Then, when the limiting plate 17 is horizontal, the two ends of the limiting plate 17 are respectively located directly below the rain shield mesh plate 3 and the rain shield plate 4; at the same time, a limiting protrusion 18 is arranged above the limiting plate 17 located between the fixed shaft 171 and the rain shield mesh plate 3; an elastic limiting support 19 is arranged below the limiting plate 17 located between the fixed shaft 171 and the rain shield plate 4; and a protrusion 35 protruding toward one side of the rain shield plate 4 is arranged on the top of the rain shield mesh plate 3.

[0034] Specifically, when the rain shield mesh plate 3 drops to the lowest height, the protrusion 35 abuts against one end of the limit plate 17 and drives one end of the limit plate 17 to tilt up and control the rain shield plate 4 to move upward until the end of the limit plate 17 close to the rain shield plate 4 abuts against one side of the rain shield plate 4, that is, at this time, the limit plate 17 loses its blocking effect on the downward movement of the rain shield plate 4; when the rain shield plate 4 is completely dropped, at this time, under the action of the elastic limit support 19 and the limit protrusion 18, the end of the limit plate 17 close to the rain shield mesh plate 3 is located directly above the rain shield mesh plate 3, and the other end is located directly above the rain shield plate 4, thereby avoiding directly controlling the upward movement of the rain shield mesh plate 3 at this time, and at this time, the rain shield mesh plate 3 can be controlled to move upward only after the rain shield plate 4 is controlled to be raised above until its bottom end is higher than the limit plate 17.

[0035] Specifically, the elastic limiting support member 19 includes a sleeve and a movable rod which are sleeved and matched with each other, a spring is connected between the sleeve and the movable rod, and a spherical structure is arranged at the end of the movable rod.

[0036] In order to guide the traction rope A40, traction rope B30 and traction rope C20 during use, a guide mechanism for guiding the traction rope A40, traction rope B30 and traction rope C20 is provided between the two side plates located between the rotating shaft 72 and the distribution cabinet body 1, and a guide structure 6 for guiding the traction rope A40, traction rope B30 and traction rope C20 is provided on the top side surface of the rectangular frame 12 directly above the filter cleaning structure 2, the rain shield mesh plate 3 and the rain shield plate 4.

[0039] When in use, when the control motor 7 is rotated to drive the rotating shaft 72 to rotate, the traction rope A40 and the traction rope B30 can be conveniently controlled to be wound or released.

[0040] Specifically, a vertical tube 5 is provided in the distribution cabinet body 1 between the guide rod A101 and the guide rod B102; Figure 12-13 , openings C for the nylon rope to pass through are respectively provided on both sides of the tube body 5, and a weight ring 51 is provided inside the tube body 5 and is sleeved on the nylon rope, and an induction structure is provided inside the tube body 5 directly below the weight ring 51; the induction structure includes a convex ring 50 provided inside the tube body 5, the upper surface of the convex ring 50 is connected to a movable plate 53 through a spring B52, a through hole 54 is provided in the middle of the movable plate 53, and the bottom side surface of the movable plate 53 located at the through hole 54 is connected to a base plate A5 through a spring C541 5. The upper surface of the base plate A55 is connected to a mounting plate 56 through a spring D551, and a pressure sensor 561 is arranged on the upper surface of the mounting plate 56; the bottom side surface of the movable plate 53 is connected to a threaded ring 57 through a spring E571, and a threaded rod 58 is connected to the threaded ring 57, and the top of the threaded rod 58 passes through a through hole 54 and is installed with a bearing plate 59; under the action of the gravity of the counterweight ring 51, the bearing plate 59 abuts against the upper surface of the base plate A55, and the bottom end of the threaded rod 58 abuts against the pressure sensor 561.

[0041] Based on the setting of the tube body 5, when in use, it can store the traction rope A40 and the traction rope B30 released from the winding drum A73 and the winding drum B75 to avoid controlling the rain shield mesh plate 3 to fall. When the rain shield plate 4 has not fallen, the traction rope A40 released from the winding drum A73 is in a relaxed state, that is, the traction rope A40 is controlled by the counterweight ring 51 to be stored in a tensioned state in the tube body; at the same time, when the control motor 7 rotates to drive the rotating shaft 72 to rotate, the rain shield plate 4 is driven to fall, and the traction rope B30 released from the winding drum B75 is in a relaxed state, that is, the traction rope B30 is controlled by the counterweight ring 51 to be stored in a tensioned state in the tube body.
