[0002] A lightning arrester is a device used for overvoltage protection. When a lightning-induced overvoltage or a switching-operation-induced overvoltage occurs, the lightning arrester diverts the current to the ground for discharge, limits the amplitude of the overvoltage on the protected device, and prevents electrical equipment from being damaged or punctured. During the production of lightning arresters, the resistor chips are stacked and placed on a core board for winding and fixing, and then they are piled up and placed in an oven for drying. Since the lengths of core bodies with different specifications are different and the positions of the heating tubes are fixed, the core bodies are prone to uneven heating and deformation when heated by the heating tubes, thereby affecting the production quality of the lightning arresters.

Detailed implementation manner

[0025] The following are specific embodiments of the present utility model and in combination with the accompanying drawings, the technical solutions of the present utility model will be further described.

[0026] As Figures 1-4 shown, a drying device for an arrester core body includes:

[0027] A machine housing 3, on which support plates 1 are symmetrically arranged, a sprocket set 28 is rotatably arranged on the support plates 1, and a chain 29 is arranged on the sprocket set 28;

[0028] A transmission unit 2, which is arranged on the support plate 1, the transmission unit 2 includes a motor 21 and a first rotating shaft 25 arranged at the output end of the motor 21, and the first rotating shaft 25 is matched with the sprocket set 28;

[0029] A clamping unit 6, which is linearly arranged between the two chains 29, the clamping unit 6 includes a base plate 65 and a first clamping rod 61 and a second clamping rod 62 symmetrically slid between the base plates 65, and first sliders 651 and second sliders 652 are respectively arranged at the ends of the first clamping rod 61 and the second clamping rod 62;

[0030] The base plate 65 is respectively rotatably provided with a first screw 653 and a second screw 656, the first screw 653 is threadedly connected with the first slider 651, and the second screw 656 is threadedly connected with the second slider 652;

[0031] A heat lamp 5, which is arranged between the support plates 1, and the heat lamp 5 irradiates towards the clamping unit 6.

[0032] Specifically, support plates 1 are clamped on both sides of the casing 3. The support plates 1 are used to support the sprocket set 28, the chain 29, and the heat lamp 5. At least three heat lamps 5 are provided, two of which are arranged on one side close to the motor 21, and the other is located at the baffle 4. The transmission unit 2 is arranged on the support plate 1. The transmission unit 2 includes a motor 21 and a first rotating shaft 25 arranged at the output end of the motor 21. The first rotating shaft 25 is matched with the sprocket set 28. The clamping units 6 are multiple and evenly distributed on the chain 29. The more clamping units 6 there are, the more cores can be dried correspondingly. When the cores need to be dried, the first screw rod 653 and the second screw rod 656 are rotated according to the model and size of the cores, so as to control the distance between the two first clamping rods 61 and the two second clamping rods 62. When the cores are placed on the clamping units 6, the shaking phenomenon during the drying process is reduced. Then, the motor 21 is used to control the sprocket set 28 to engage the chain 29 to move, so that the heat lamp 5 can evenly dry each part of the cores, improving the drying effect on the cores.

[0033] As a further embodiment provided by the present utility model, the transmission unit 2 further includes a bracket 22 fixed on the support plate 1. The bracket 22 is matched with the motor 21. A coupling 23 that is engaged with the first rotating shaft 25 is arranged at the output end of the motor 21. The model of the motor 21 is MHMF042L1U2M2. The bracket 22 supports the motor 21 to make its output more stable. One end of the coupling 23 is clamped on the output shaft of the motor 21, and a serrated part is arranged at the other end. The serrated part is attached to the first rotating shaft 25 to improve the transmission effect of the coupling 23.

[0034] As a further embodiment provided by the present utility model, the chain 29 is composed of multiple chain links. A support block 64 is arranged on the chain link. A support rod 63 that is matched with the bottom plate 65 is rotatably arranged on the support block 64. The bottom plate 65 is rotatably connected to the support block 64 through the support rod 63. In this way, the bottom plate 65 is always perpendicular to the ground under its own gravity, enabling the heat lamp 5 to better heat the cores.

[0035] As a further embodiment provided by the present utility model, a clamping block 632 that is matched with the support block 64 is slidably arranged on the support rod 63. A spring 631 is arranged between the clamping block 632 and the support rod 63. The clamping block 632 is pressed to make it snap into the support block 64, so as to limit the bottom plate 65 and prevent the bottom plate 65 from shaking on the support block 64, facilitating the installation of the cores onto the clamping units 6.

[0036] As a further embodiment provided by the present utility model, knobs 654 are arranged on both the first screw rod 653 and the second screw rod 656. By respectively rotating the knobs 654, the rotation of the first screw rod 653 and the second screw rod 656 can be controlled, thereby controlling the sliding of the first clamping rod 61 or the second clamping rod 62 on the bottom plate 65, and adjusting the distance between the two first clamping rods 61 and the two second clamping rods 62 to adapt to cores of different specifications and sizes.

[0037] As a further embodiment provided by the present utility model, clamping blocks 71 are symmetrically arranged on the second clamping rod 62. A locking sleeve 73 that cooperates with the second clamping rod 62 is clamped on the clamping blocks 71. A lever 72 is threadedly connected to the locking sleeve 73. When the core is placed on the second clamping rod 62, by moving the clamping blocks 71 to fit against the core and swinging the lever 72, the core can be fixed to the center of the second clamping rod 62 through the two locking sleeves 73.

[0038] As a further embodiment provided by the present utility model, an observation plate 31 is arranged on the machine shell 3. The observation plate 31 is a transparent plate. When drying the core, the drying process of the core can be observed through the observation plate 31.

[0039] As a further embodiment provided by the present utility model, the sprocket group 28 includes sprockets. A second rotating shaft 26 is arranged at the axis center of the sprocket. A bearing 27 that is clamped on the support plate 1 is arranged at the end of the second rotating shaft 26. The use of the bearing 27 improves the rotation effect of the second rotating shaft 26 and makes the transmission of the sprocket group 28 more stable.

[0040] As a further embodiment provided by the present utility model, a chute is formed on the support plate 1. A baffle 4 is slidably arranged in the chute. Push blocks 41 are symmetrically arranged on the baffle 4. A rubber strip is arranged along the edge of the baffle 4. When the baffle 4 is slid away from the machine shell 3, it is for installing the core for drying, and when the baffle 4 is in contact with the machine shell 3, it is for preventing the heat inside the machine shell 3 from dissipating and reducing energy consumption.

[0041] Working principle: First, slide the baffle plate 4 along the support plate 1 to expose the clamping unit 6 inside the casing 3. According to the length and size of the core body in advance, rotate the knob 654 to control the rotation of the first screw rod 653 and the second screw rod 656 respectively, so that the first clamping rod 61 and the second clamping rod 62 slide relatively to adjust their spacing, so as to adapt to core bodies of different specifications. Then, place the core body on the first clamping rod 61 and the second clamping rod 62, push the clamping blocks 71 at both ends of the second clamping rod 62 to slide and fit the core body, and rotate the lever 72 to fix the core body at the central position of the clamping unit 6 through the locking sleeve 73, so that it can cooperate better with the heat lamp 5. Then, control the sprocket group 28 to engage the chain 29 to move through the motor 21, so as to fix the core bodies on the clamping unit 6 one by one. Then, push the baffle plate 4 to fit the casing 3, and the chain 29 drives the core bodies on the clamping unit 6 to move, so as to uniformly dry the core bodies up, down, left and right through the heat lamp 5, improving the drying effect of the core bodies.
