Description

Technical Field

[0001] This utility model belongs to the technical field of insulator storage equipment, and particularly relates to a blank storage device for suspension insulator production. Background Technology

[0002] Suspension insulators are generally made of insulating components (such as porcelain or glass components) and metal accessories (such as steel feet, iron caps, flanges, etc.) glued together or mechanically clamped together. Before assembly, the blanks are usually stored in a storage device, and the storage environment needs to be kept dry to prevent the electrical performance and mechanical strength of the blanks from being affected. Common insulator blank storage devices are composed of storage boxes. For example, a blank storage device for the production of suspension insulators for lines disclosed in patent application number CN202022508343.2 includes a base plate, on which four sets of columns are fixedly installed. A first connecting rod is fixedly installed on one side of each column, and a second connecting rod is fixedly connected to one end of the first connecting rod. A third groove is opened on one side of each column, and the second connecting rod is fixedly installed inside the third groove by bolts. A tray is provided on the four sets of first connecting rods, and a protrusion is fixedly installed on the first connecting rod. A first groove is opened on one side of each tray, and the protrusion is engaged inside the first groove. A second groove is opened on the other side of each tray, and a slot is opened at the bottom of the second groove.

[0003] The existing storage device lacks active means to adjust the storage environment during use, which makes the storage of embryos susceptible to environmental changes and reduces the storage effect of the device. Therefore, it is necessary to make improvements. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a blank storage device for suspension insulator production, thereby effectively improving the storage efficiency of the blank storage device.

[0005] In view of this, the present invention provides a blank storage device for suspension insulator production, comprising:

[0006] A storage box, wherein the storage box is provided with a storage cavity and several trays;

[0007] A movable base is provided at the bottom of the storage box for moving the storage box;

[0008] Also includes:

[0009] A drying mechanism is installed in a storage box. The drying mechanism can drive the air in the storage box to circulate internally and dry the air in the internal circulation state.

[0010] The drying mechanism is controlled by a controller, and the tray has air circulation holes.

[0011] In this technical solution, when the humidity inside the storage tank exceeds a set threshold (e.g., 60%RH), the controller activates the drying mechanism. The drying mechanism circulates the air inside the storage tank, drying the air in this circulated state. As the circulation continues, the humidity inside the storage tank gradually decreases. When the humidity drops to a set lower limit (e.g., 40%RH), the controller stops the drying mechanism, ending the drying process. By configuring the drying mechanism, the air inside the storage tank can be circulated and dried, effectively controlling the humidity inside the storage tank and preventing the embryos from becoming damp, which could affect their electrical performance and mechanical strength, thus significantly improving the quality of embryo storage.

[0012] In the above technical solution, the drying mechanism further includes:

[0013] Air duct, which is installed on the top inner wall of the storage box;

[0014] A desiccant filter, wherein the desiccant filter is disposed in the air duct;

[0015] A fan, wherein the fan is installed in the duct and is located on one side of the desiccant filter;

[0016] An air inlet is provided at the left end of the duct to guide air into the duct.

[0017] An air outlet is provided at the right end of the duct to guide air out of the duct.

[0018] The fan can drive the air in the storage box to circulate internally. The air in the internal circulation state enters the air duct from the air inlet and returns to the storage box from the air outlet after passing through the desiccant filter.

[0019] Furthermore, the above technical solution also includes:

[0020] A heater, wherein the heater is disposed in the air duct and located between the air inlet and the desiccant filter;

[0021] The desiccant filter is a regenerable desiccant filter. The air inlet has two air inlets and one air outlet. The two air inlets are connected to the internal environment of the storage box and the external environment, respectively. The air outlet has two air outlets and one air outlet. The two air outlets are connected to the internal environment of the storage box and the external environment, respectively. The two air inlets and two air outlets are opened and closed by dampers.

[0022] Furthermore, the above technical solution also includes:

[0023] Anti-collision strips are installed on the outer surface of the storage box to reduce vibrations or impacts transmitted into the storage box.

[0024] In the above technical solution, the anti-collision strip further includes:

[0025] A connecting strip, wherein the inner end of the connecting strip is provided with a first elastic deformation cavity and the outer end of the connecting strip is provided with a slot;

[0026] The intermediate strip has an insert at its inner end that mates with a slot, a plurality of second elastic deformation cavities in its inner end, and a positioning protrusion at its outer end.

[0027] The contact strip has a positioning groove at its inner end that mates with the positioning protrusion.

[0028] The connecting strip, the intermediate strip, and the contact strip are interconnected, and the connecting strip is connected to the outer side of the storage box.

[0029] The beneficial effects of this utility model are:

[0030] 1. The drying mechanism enables the air inside the storage box to circulate and dry, effectively controlling the humidity inside the storage box and preventing the embryos from being affected by moisture, thus significantly improving the quality of embryo storage.

[0031] 2. The use of a regenerable desiccant filter, combined with a heater and a design that connects the air inlet and outlet to the external environment, enables desiccant regeneration, reduces the frequency of desiccant replacement, lowers operating costs, and improves the economic efficiency and environmental friendliness of the equipment.

[0032] 3. The multi-segment structure design of the anti-collision strip and the setting of the elastic deformation cavity can effectively absorb and reduce the vibration and collision impact transmitted from the outside to the storage box, avoid damage to the embryo due to vibration or collision, and improve the safety of the storage process.

PTC heater 4 features rapid heating and stable temperature control, meeting the temperature requirements for desiccant regeneration.

[0055] Anti-collision strip

[0056] The anti-collision strip 5 is made of EVA material, which has good elasticity and cushioning performance. The anti-collision strip 5 is arranged on the side walls of the left and right sides of the storage box 1 and the outer wall of the box door. The length of each anti-collision strip 5 is adapted to the height of the corresponding side of the storage box 1.

[0057] The connecting strip 50 is 1200mm long, 50mm wide, and 10mm thick. The first elastic deformation cavity 51 at the inner end is a long, narrow cavity extending along the length of the connecting strip 50. The slot 52 at the outer end is a T-shaped groove with a width of 20mm and a depth of 15mm, extending along the length of the connecting strip 50, open at both ends, with the outer end also open. The connecting strip 50 has two 8mm diameter holes spaced 300mm apart for bolt connection.

[0058] The intermediate strip 53 has the same length as the connecting strip 50, a width of 40mm, and a thickness of 10mm.

The connecting strip 50, the intermediate strip 53, and the contact strip 57 are initially connected and positioned by the engagement of the insert 54 with the slot 52, and the positioning protrusion 56 with the positioning groove 58. Then, M6 bolts are passed through the holes and connected and fixed to the screw holes on the outer side of the storage box 1.

[0060] Controllers and sensors

[0061] The controller employs an STM32 series embedded microcontroller, specifically the STM32F103C8T6, which features abundant I / O interfaces and excellent control performance. The controller is housed in a control box on the side of storage tank 1. The control box surface includes a display screen and operation buttons. The display screen shows the real-time temperature and humidity parameters within storage tank 1 and the device's operating status. The operation buttons are used to manually set operating parameters and control modes. The temperature and humidity sensor is a model SHT30, offering high-precision temperature and humidity measurement capabilities. Its measurement range is 0-100%RH for humidity and -40-125℃ for temperature, with an accuracy of ±2%RH for humidity and ±0.3℃ for temperature. The sensor is installed in the center of storage tank 1 and near the desiccant filter 31, respectively, to monitor the ambient humidity within storage tank 1 and the temperature during regeneration, transmitting the data to the controller in real time.

[0062] Work process

[0063] Drying Mode: When the humidity inside storage tank 1 exceeds a set threshold (e.g., 60%RH), the controller receives a signal from the temperature and humidity sensor and activates the drying mode. At this time, the air inlet 330 damper 35, which connects the air inlet 33 to the internal environment of storage tank 1, opens, while the air inlet 330 damper 35, which connects to the external environment, closes. Similarly, the air outlet 340 damper 35, which connects the air outlet 34 to the internal environment of storage tank 1, opens, while the air outlet 340 damper 35, which connects to the external environment, closes. The fan 32 starts, and under its influence, air from storage tank 1 enters the duct 30 through the internal air inlet 330 of the air inlet 33. The air first passes through the heater 4 (which is not operating at this time, only in regeneration mode), then flows through the desiccant filter 31. Moisture in the air is absorbed by the desiccant, and the dried air is discharged from the internal air outlet 340 of the air outlet 34, returning to storage tank 1, forming an internal air circulation. As the cycle continues, the humidity inside storage box 1 gradually decreases. When the humidity drops to the set lower limit (e.g., 40%RH), the controller shuts off the fan 32, and the drying mode stops.

[0064] Desiccant Regeneration Mode: When the desiccant reaches saturation due to moisture adsorption (this can be determined by observing the color change of the silica gel or by the controller based on the running time), regeneration is required. At this time, the controller activates the regeneration mode. The air inlet 330 damper 35, connecting the air inlet 33 to the external environment, opens, while the air inlet 330 damper 35, connecting the air inlet 330 to the internal environment of the storage tank 1, closes. Similarly, the air outlet 340 damper 35, connecting the air outlet 34 to the external environment, opens, while the air outlet 340 damper 35, connecting the air outlet 340 to the internal environment of the storage tank 1, closes. Simultaneously, the heater 4 and fan 32 start. External air enters the duct 30 from the external air inlet 330 of the air inlet 33. After being heated by the heater 4, the high-temperature air flows through the desiccant filter 31, causing the moisture in the desiccant to evaporate. The evaporated humid air is then discharged to the external environment from the external air outlet 340 of the air outlet 34. During the regeneration process, the controller monitors the temperature sensor signal near the desiccant filter 31 and controls the power of the heater 4 to maintain the temperature within a suitable range, ensuring effective regeneration. After regeneration is complete, the controller shuts off heater 4 and fan 32, closes external air inlet 330 and air outlet 340 damper 35, and opens internal air inlet 330 and air outlet 340 damper 35, and the device returns to the drying state.
