Description

Technical Field

[0001] The present invention relates to the technical field of electric meter boxes, in particular to a multifunctional electric meter box. Background Art

[0002] The meter box is a device used to store electric meters. The material used to manufacture the low-voltage cable branch box is a resin-based composite material. The main components of the box are ABS engineering plastics, polycarbonate transparent PC material, DMC, and SMC, which are injection molded and pressed.

[0003] The outside of the meter box is usually provided with slots for ventilation and heat dissipation. In order to obtain a better heat dissipation effect, some meter boxes will choose to enlarge the opening of the heat dissipation slot or increase the number of heat dissipation slots. As a result, when the meter box is used for a long time, especially when used outdoors, pollutants may enter the meter box through the heat dissipation slots, causing damage to the components inside the meter box and shortening the service life of the meter box. In addition, some meter boxes use heat dissipation slots for passive heat dissipation, and the heat dissipation efficiency is relatively limited. Summary of the Invention

[0004] The object of the present invention is to provide a multifunctional electric meter box to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention adopts the following technical solution: a multifunctional electric meter box, comprising a supporting base column, a group of electric meter boxes connected to the top of the supporting base column, a heat dissipation net provided on the rear end surface of the electric meter box, an opening and closing mechanism provided at the rear end of the electric meter box near the heat dissipation net, and a heat dissipation mechanism connected to the bottom end of the electric meter box;

[0006] The opening and closing mechanism includes an unfolding mechanism, a front layer, a side layer and a covering layer. The unfolding mechanism is provided at the rear end of the meter box near the heat dissipation network. The front top of the unfolding mechanism is connected to the front layer, the left and right tops are both provided with side layers, and the rear end is connected to the covering layer.

[0007] By adopting the above technical solution, the heat dissipation net and the opening and closing mechanism can work together. When heat dissipation is not required, the covering layer of the opening and closing mechanism automatically covers the heat dissipation net, which can effectively block the entry of external pollutants and extend the service life of the meter box. When heat dissipation is required, the heat dissipation net is unfolded through the opening and closing mechanism to ensure air circulation inside the meter box and prevent the equipment from overheating. It also cooperates with the heat dissipation mechanism at the bottom of the meter box to improve the internal air circulation effect of the meter box and enhance the heat dissipation efficiency.

[0008] Preferably, the unfolding mechanism includes opening and closing parts, which are provided in two groups, upper and lower, in a mirror-image arrangement; a group of connecting frames are provided at both left and right ends of the bottom surface of the lower opening and closing parts, and a group of rollers are provided between the two groups of connecting frames.

[0009] By adopting the above technical solution, the upper and lower sets of opening and closing parts arranged in a mirrored manner can ensure synchronous movement through mechanical linkage, thereby achieving smooth expansion or closing of the covering surface layer to avoid unilateral jamming. The expansion mechanism can be quickly and symmetrically expanded or retracted to enhance overall rigidity and coordinate movements. The roller can recycle the front layer to avoid the front layer occupying the internal space of the meter box.

[0010] Preferably, a group of slide grooves are provided at the middle ends of the two groups of opening and closing parts, and a group of sliders are connected to the slide grooves. The front end surface of the slider at the lower end is connected to the front bottom end of the opening and closing part at the lower end through an electric push rod. The rear ends of the two groups of sliders are provided with a group of movable plates, and the left and right positions of the rear end surfaces of the two groups of opening and closing parts are connected to a group of gears. The upper and lower groups of gears are connected by two groups of connecting arms, and the opposite ends of the upper and lower groups of connecting arms are hinged to each other.

[0011] By adopting the above technical solution, the electric push rod pushes the lower end slider to slide in the slide groove, thereby driving the movable plate and the two sets of connecting arms at the lower end to move, and linking the upper end opening and closing parts to move upward, so as to achieve accurate and stable deployment of the deployment mechanism. The electric push rod provides linear motion, which can avoid mechanical shock and extend the service life. It has high-precision, strong synchronization and low failure rate opening and closing functions, which is suitable for outdoor meter box protection scenarios that require frequent adjustment or intelligent response, while taking into account structural strength and energy saving requirements.

[0012] Preferably, the heat dissipation mechanism includes a connecting sleeve, a driving motor, a movable disk and a fan. A group of connecting sleeves is connected to the top of the supporting base column. The bottom end of the connecting sleeve is connected to the top of the supporting base column. A group of driving motors is provided at the rear end, and a group of movable disks is connected to the top of the connecting sleeve. A group of fans are provided at the left and right ends of the top surface of the movable disk.

[0013] By adopting the above technical solution, the connecting sleeve is fixed to the top of the supporting base column, which can serve as the bearing frame of the heat dissipation mechanism and form an integrated structure with the meter box, saving space and facilitating maintenance. The two sets of fans are symmetrically arranged on the top surface of the movable disk and extend to the inner end of the meter box. The fans can directly blow air into the meter box, thereby accelerating the air flow inside the meter box and accelerating the discharge of heat from the meter box.

[0014] Preferably, a group of notches is provided at the middle end of the connecting sleeve, and a group of filling plates is connected to the outer front end of the connecting sleeve through a connecting plate, and the filling plates are located in the center of the notches.

[0015] Preferably, the bottom end of the movable disk is connected to a group of movable inner cylinders, the front middle end of the movable inner cylinder is provided with a group of fixed shafts, the rear end of the movable inner cylinder is connected to a group of rotating shafts, the front end of the rotating shaft is provided with a group of linkage frames, and the front upper and lower ends of the linkage frames are both provided with a group of limiting rods.

[0016] By adopting the above technical solution, the rotation of the rotating shaft can drive the fixed shaft and the movable inner cylinder to move in the connecting sleeve through the linkage frame and the limit rod. A sliding fit can be formed between the movable inner cylinder and the inner wall of the connecting sleeve to reduce wear and perform low-friction rotation. The two sets of limit rods and the fixed shaft can prevent the movable disk from tilting or getting stuck due to the weight imbalance of the fan, thereby achieving stable rotation and precise limiting of the movable disk.

[0017] Preferably, the front end of the fixed shaft extends through the notch, and the rear end is located between the two sets of limiting rods.

[0018] By adopting the above technical solution, the fixed shaft can move along the inner side of the notch through the rotation of the two sets of limit rods.

[0019] Preferably, the front end of the driving shaft of the driving motor extends through the connecting sleeve and is connected to the rear end of the rotating shaft.

[0020] By adopting the above technical solution, the driving motor drives the shaft to rotate, thereby driving the rotating shaft to rotate.

[0021] Preferably, the outer side of the movable inner cylinder is hollowed out.

[0022] By adopting the above technical solution, the weight can be effectively reduced and the stability of the movable disk during movement can be improved.

[0023] Preferably, a through groove in the shape of a square is formed between the notch and the filling plate, and the front end of the fixed shaft can move along the through groove.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention uses an opening and closing mechanism disposed at the rear end of the electric meter box. The opening and closing mechanism includes an expansion mechanism, a front layer, a side layer, and a covering surface layer. The opening and closing mechanism cooperates with the covering surface layer to open or close the heat dissipation net. Thus, when the electric meter box does not need to dissipate heat, the heat dissipation net can be sealed and covered. This can effectively prevent external contaminants from entering the electric meter box through the heat dissipation net, effectively extending the service life of the electric meter box.

[0026] 2. The present invention uses a heat dissipation mechanism disposed at the bottom of the meter box. The heat dissipation mechanism includes a connecting sleeve, a drive motor, a movable plate, and a fan. Both sets of fans extend to the bottom of the meter box to drive air flow inside, achieving active exhaust and heat dissipation of the meter box. This can effectively improve the heat dissipation effect of the meter box, enhance the internal air circulation effect of the meter box, and enhance the heat dissipation efficiency.

[0027] 3. The present invention cooperates with other components such as the movable inner cylinder, fixed shaft, rotating shaft, linkage frame and limit rod arranged at the bottom of the movable disk. The driving motor can drive the rotating shaft, linkage frame and limit rod to rotate, thereby driving the movable inner cylinder, fixed shaft and the fan on the top surface of the movable disk to rotate back and forth up and down, adjusting the air supply angle, effectively covering the area inside the meter box, further enhancing the internal air flow effect of the meter box, strengthening the heat dissipation effect of high-temperature parts, and higher heat dissipation efficiency.

When the unfolding mechanism 41 is retracted, the side layers 43 can be retracted by compressing the pleats to avoid occupying the internal space of the electric meter box 2. The rear end of the unfolding mechanism 41 is fixedly connected to the covering layer 44 that can cover the heat dissipation net 3.

[0041] Specifically, the heat dissipation net 3 and the opening and closing mechanism 4 can work together.

[0045] Specifically, the electric push rod 4113 pushes the lower slider 4112 to slide in the slide groove 4111, thereby driving the movable plate 4114 and the two sets of connecting arms 4116 at the lower end to move, and linking the upper opening and closing part 411 to move upward, so as to realize the precise and stable expansion of the expansion mechanism 41. The electric push rod 4113 provides linear motion to avoid mechanical shock and extend the service life.
