Description

Technical Field

[0001] The invention relates to an adaptive cooling distribution box, belonging to the technical field of distribution boxes. Background Art

[0002] A distribution box is a box used to install electrical components and make connections. It is a type of power equipment that is widely used in power transmission and distribution networks and plays a very important role. Electrical components such as switchgear, measuring instruments, protective devices, and other auxiliary equipment are assembled inside the distribution box in accordance with electrical wiring requirements to meet the requirements for normal operation of the power transmission and distribution network. Existing distribution boxes usually have a heat sink on their box to dissipate heat inside the box. However, for distribution boxes installed in outdoor environments, rainwater can easily splash into the box from the heat sink on rainy days, causing moisture inside the distribution box, which puts the electrical components in the distribution box at risk of moisture, short circuit, and damage.

[0003] A Chinese patent with announcement number CN115764627A discloses an outdoor distribution box with a rainproof structure. Rainwater flows down along the prismatic surface of the top cover, and the water retaining strip on the lower surface of the top cover effectively blocks the rainwater to prevent it from shrinking along the top cover. At the same time, the wind blown out by the blower mechanism will be discharged through two sets of ventilation slots and air inlet slots to prevent rainwater from entering. The outer air guide frame opens downward to prevent rainwater from entering the box through the ventilation slots. At the same time, the air inlet of the box can accelerate the circulation of airflow and improve the heat dissipation efficiency, thereby blowing and drying the box and improving the safety of electronic components and circuits inside the distribution box; the temperature and humidity in the box are detected by a temperature sensor and a humidity sensor, so as to control the operation of the blower mechanism and the heater, dissipate heat and dry the box, prevent snow from accumulating on the surface of the top cover, and ensure the internal temperature of the distribution box. Although it can prevent rainwater from entering on rainy days, it is impossible to switch the box to different heat dissipation states according to weather changes, resulting in limited waterproof and heating effects.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] See also Figure 1-10 A self-adaptive cooling distribution box comprises a box body 1, a box door 2 hinged to one side of the box body 1 and a frame 4 fixedly connected to the box body 1 for placing electrical components; a row of side heat dissipation grilles 11 are respectively provided on the surrounding sides of the box body 1. When the electrical components are in use, they will emit heat. The side heat dissipation grilles 11 are used to realize the flow and exchange of air inside and outside the box body 1, so as to dissipate heat in the box body 1; each side heat dissipation grille 11 is provided with a water retaining plate 5 matched therewith and arranged in the box body 1. On rainy days, the side heat dissipation grille 11 is shielded by the water retaining plate 5 to prevent rainwater from entering the box body 1 and causing the electrical components to be damp and damaged.

[0034] A water collecting tank 8 is arranged on the top of the box body 1, and an S-shaped water pipe 81 is arranged at the bottom of the water collecting tank 8 and is connected thereto. The free end of the S-shaped water pipe 81 extends into the box body 1 and passes through the adjacent side wall of the box body 1. The S-shaped water pipe 81 is placed between the frame 4 and the side heat dissipation grille 11 opposite to the Yuxiang door. In rainy weather, when the box body 1 is in a sealed state, the water collecting tank 8 collects rainwater, and the rainwater is guided by the S-shaped water pipe 81 to flow in the box body 1 and is discharged from the side wall of the box body 1. In the process of rainwater flowing, the heat generated by the operation of electrical components is taken away by heat exchange, thereby reducing the temperature of the box body 1.

[0035] A temperature sensor 31, a humidity sensor 32, a heater 33 and a controller 3 electrically connected to the three are arranged in the box 1. When the box 1 is in a sealed state, the controller 3 controls the operation of the heater 33 according to the signals transmitted by the temperature sensor 31 and the humidity sensor 32, so that the temperature and humidity in the box 1 are kept appropriate.

[0036] Furthermore, an upper heat sink 12 is provided on the top of the box body 1. When the electrical components generate heat during operation, the heat rises and is discharged from the upper heat sink 12, further enhancing the heat dissipation function of the box body 1; the upper heat sink 12 and the water collecting tank 8 are respectively arranged on both sides of the top of the box body 1, wherein the water collecting tank 8 is formed by the concave top surface of the box body 1, and its cross-section is arc-shaped, which increases the rainwater holding capacity and accelerates the speed at which rainwater converges to the S-shaped water pipe 81; a linear water retaining bar 9 is provided between the upper heat sink 12 and the water collecting tank 8 to separate the two, and the side of the water collecting tank 8 away from the linear water retaining bar 9 is lower than the side close to the linear water retaining bar 9, which can prevent overflowing rainwater from flowing to the upper heat sink 12; a shielding plate 6 is provided above the upper heat sink 12 to shield it, and on rainy days, the upper heat sink 12 is shielded by the shielding plate 6 to prevent rainwater from falling into the box body 1.

[0037] A U-shaped water retaining strip 10 is arranged on the side of the upper heat dissipation grille 12 away from the water collecting tank 8. The U-shaped water retaining strip 10 and the straight water retaining strip 9 are both fixedly connected to the top of the box body 1, and the U-shaped water retaining strip 10 and the straight water retaining strip 9 cooperate to enclose the upper heat dissipation grille 12; when the shielding plate 6 shields the upper heat dissipation grille 12, the bottom surface of the shielding plate 6 is in contact with the top surfaces of the U-shaped water retaining strip 10 and the straight water retaining strip 9, and the periphery of the shielding plate 6 covers the U-shaped water retaining strip 10 and the straight water retaining strip 9, so that rainwater cannot penetrate into the gap between the shielding plate 6 and the U-shaped water retaining strip 10 and the straight water retaining strip 9.

[0038] Furthermore, the shielding plate 6 can be displaced laterally along the width direction of the box body 1 to adjust the two modes of shielding the upper heat dissipation grille 12 and shielding the water collecting tank 8, and cooperate with the opening and closing of the side heat dissipation grille 11 to enable the box body 1 to switch between a full heat dissipation state, a partial heat dissipation state, and a sealed state to adapt to different weather conditions.

[0039] The top surface of the box body 1 is also provided with two slide rails 13 which are arranged on both sides of the upper heat dissipation grille 12. On sunny days, the slide rails 13 can also be used as heat dissipation channels; the two slide rails 13 are arranged along the width direction of the box body 1 and are placed in the area enclosed by the U-shaped water retaining strip 10 and the linear water retaining strip 9. A connecting column 14 is vertically arranged in each slide rail 13. The upper part of the connecting column 14 is fixedly connected to the shielding plate 6, and the lower part of the connecting column 14 extends into the box body 1 and is connected to a transmission structure 7 that drives it to reciprocate laterally along the slide rail 13. The lower part of the transmission structure 7 is connected to the adjacent water retaining plate 5; a rotating structure 7' connected to the water retaining plate 5 opposite to the box door 2 is provided above the water retaining plate 5, and the rotating structure 7' is connected to the box body 1.

[0040] The controller 3 controls the transmission mechanism to rotate synchronously in the same direction, driving the shielding plate 6 to adjust its shielding mode while driving the water baffle 5 connected thereto to move vertically to open and close the adjacent side radiator grille 11; the controller 3 controls the rotating structure 7' to rotate and drive the water baffle 5 connected thereto to move vertically to open and close the adjacent side radiator grille 11.

[0041] In order to further enhance the smooth and stable movement of the shielding plate 6, balls 101 are embedded on both sides of the connecting column 14 and the top surfaces of both sides of the U-shaped water retaining strip 10, and ball grooves that cooperate with adjacent balls 101 are provided on the inner wall of the slide rail 13 and the bottom surface of the shielding plate 6.

[0042] The top of the shielding plate 6 is tilted, and the side of the shielding plate 6 away from the water collecting tank 8 is higher than the side close to the water collecting tank 8. On rainy days, rainwater falling on the shielding plate 6 can flow into the water collecting tank 8, thereby improving its water storage efficiency.

[0043] Furthermore, the transmission structure 7 and the rotating structure 7' both include a wheel disc 71, an eccentric arc plate 72 fixedly connected to the side of the wheel disc 71 away from the box body 1, and the arc surface of the eccentric arc plate 72 is placed on the outer periphery of the wheel disc 71; the wheel disc 71 is rotatably connected to the adjacent side wall of the box body 1 through a rotating shaft, and the controller 3 controls the rotation of the rotating shaft through a through-hole rotating shaft motor 73.

[0044] The two ends of the top of each water baffle plate 5 are connected to the top of the box body 1 through a spring 51, and the middle part of the top surface of the water baffle plate 5 is concave to form an arc groove 52. When the arc groove 52 abuts against the eccentric arc plate 72, the transverse groove 53 on the water baffle plate 5 corresponds to the position of the side heat dissipation grille 11, and the side heat dissipation grille 11 is in an open state; when the shaft motor 73 drives the wheel disc 71 to rotate, the eccentric arc plate 72 rotates away from the adjacent arc groove 52, and the water baffle plate 5 moves upward under the action of elastic force until the arc groove 52 abuts against the wheel disc 71. At this time, the transverse groove 53 on the water baffle plate 5 and the side heat dissipation grille 11 are misaligned with each other, and the side heat dissipation grille 11 is in a closed state.

[0045] Furthermore, each transmission structure 7 also includes a gear 74 fixedly connected to the side of the wheel disc 71 close to the adjacent side wall of the box body 1. The gear 74 is concentrically arranged and fixedly connected to the adjacent rotating shaft, and the diameter of the gear 74 is smaller than the diameter of the wheel disc 71.

[0046] The bottom of the connecting column 14 is fixedly connected with a rack 15 parallel to the slide rail 13, and the rack 15 is meshed with an adjacent gear 74. The wheel plate 71 and the eccentric arc plate 72 are both placed on the side of the rack 15 away from the box body 1. When the gear 74 rotates, the connecting column 14 is driven to move laterally along the slide rail 13 and the eccentric arc plate 72 adjacent to it is driven to rotate.

[0047] Among them, the gears 74 in the two transmission structures 7 are connected by the same rotating shaft, so as to realize the synchronous and unidirectional rotation of the two transmission structures 7, improve the stability of the movement of the shielding plate 6, and improve the synchronization of the state of the switching side heat dissipation grille 11 of the two water retaining plates 5 connected to the transmission structure 7.

[0048] In order to ensure that the water baffle 5 remains in contact with the adjacent side wall of the box body 1 and does not shake during the vertical movement, limit grooves 54 are respectively provided at the upper and lower ends of the water baffle 5, and the limit grooves 54 are parallel to the slide rails 13. Limit blocks 16 corresponding to and matching the positions of the adjacent limit grooves 54 are respectively fixedly connected to the side walls of the box body 1, and the height of the limit blocks 16 is less than the height of the guide groove; when the arc groove 52 abuts against the eccentric arc plate 72, each limit block 16 abuts against its corresponding upper wall of the guide groove; when the arc groove 52 abuts against the wheel plate 71, each limit block 16 abuts against the corresponding lower wall of the guide groove.

[0049] Furthermore, the side heat dissipation grille 11 opposite to the box door 2 and the transverse groove 53 on the water retaining plate 5 are both arranged to be inclined downward, so that rainwater is not easy to fall into the box body 1 through them even on rainy days.

[0050] The top surface of the shielding plate 6 is fixedly connected to the rain sensor 61. The controller 3 controls the rotation of the rotating structure 7', the transmission structure 7 and the operation of the heater 33 respectively through the signals transmitted by the rain sensor 61, the temperature sensor 31 and the humidity sensor 32, thereby adjusting the different heat dissipation states of the box body 1 to adapt to different weather conditions.

[0051] Working principle of the present invention:

[0052] See also Figure 1-10 On sunny days, the box body 1 is in a full heat dissipation state. At this time, the upper heat dissipation grille 12 is exposed, the shielding plate 6 shields the water collecting tank 8, and a gap is left between the shielding plate 6 and the water collecting tank 8. Each eccentric arc plate 72 is respectively abutted against the arc groove 52 of the adjacent water retaining plate 5, so that the side heat dissipation grilles 11 are all in an open state, and the air inside and outside the box body 1 flows and exchanges through the three sides and the top of the box body 1, and the heat dissipation effect is the strongest.

[0053] On rainy days, the rain sensor 61 detects the rainfall, and the controller 3 starts the shaft motor 73 in the transmission mechanism 7 according to the signal transmitted by the rain sensor 61. The gear 74 rotates, driving the connecting column 14 to move away from the water collecting box 8, so that the shielding plate 6 shields the upper heat dissipation grille 12, and at the same time, the eccentric arc plate 72 rotates to separate from the arc groove 52 of the adjacent water baffle 5. Under the action of elastic force, through the cooperation of the limit groove 54 and the limit block 16, the water baffle 5 moves vertically upward until the arc groove 52 abuts against the wheel 71, that is, the side heat dissipation grille 11 adjacent to the water baffle 5 is closed. At this time, the side heat dissipation grille 11 opposite to the box door 2 is still in an open state, that is, the box body 1 is in a partial heat dissipation state; at the same time, the wind outside the box body 1 enters the box body 1 through the side heat dissipation grille 11 opposite to the box door 2, and the rainwater collected in the water collecting box 8 continuously flows and is discharged in the box body 1 through the guidance of the S-shaped water pipe 81, and heat exchange is continuously performed in the box body 1 to dissipate heat.

[0054] When encountering heavy rainfall, or low temperature affecting the operation of electrical components, or too high humidity in the box body 1 easily causing electrical components to be damaged by moisture, the controller 3 starts the shaft motor 73 in the rotating mechanism 7' according to the signals transmitted by the rain sensor 61, the temperature sensor 31, and the humidity sensor 32, and the wheel disc 71 opposite to the box door 2 rotates, and the eccentric arc plate 72 connected to the wheel disc 71 rotates away from the adjacent arc groove 52. At the same time, the water retaining plate 5 opposite to the box door 2 moves up to the arc groove 52 at its top under the action of elastic force and abuts against the wheel disc 71, that is, the side heat dissipation grille 11 opposite to the box door 2 is closed. At this time, the upper heat dissipation grille 12 on the top of the box body 1 and the side heat dissipation grille 11 on the side of the box body 1 are all closed, that is, the box body 1 is in a sealed state. At the same time, the controller 3 starts the heater 33 to heat the temperature in the box body 1 to maintain it at a suitable temperature and humidity for the electrical components to work normally.

[0055] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
