Description

Technical Field

[0001] The present invention belongs to the technical field of storage boxes, and particularly relates to a multifunctional storage box for power logistics infrastructure projects. Background Art

[0002] Power logistics support work plays an important role in the normal operation of the power system. With the continuous increase of power logistics equipment and the increasing functional requirements, the storage box has also developed. It has an efficient power converter, a high-security power protection system, a ventilation system, a refrigeration system, and a safe protective shell inside the storage box, and can be transported over long distances by a vehicle, ready to use immediately, with high flexibility, which has good practicality for both power logistics and infrastructure projects. At the same time, the power equipment in the storage box can be reused repeatedly, and the overall movement is more convenient, which can effectively reduce the damage of power equipment.

[0003] The existing storage box has a relatively low degree of automation. There is no automation component between the power equipment inside the storage box and the storage box, resulting in poor automation effect between the power equipment and the storage box. The staff still needs to enter the storage box to manually adjust multiple power equipment, and there is no coordination effect between the two, which also increases the work content. At the same time, due to the strong professionalism of the power equipment in the storage box, professional power personnel are often required to operate and use it. Once the power personnel are not near the storage box, it is impossible to switch, debug, and operate the power equipment, and the degree of automation is not high;

[0004] At the same time, during the movement and handling of the storage box, since there is no limiting component between the storage box and the power equipment, once the storage box tilts, the internal power equipment will slide due to gravity, which is very likely to damage the internal power equipment, resulting in the power equipment being unusable, short circuit, etc., causing economic losses and reducing the service life of the power equipment. For this reason, we propose a multifunctional storage box for power logistics infrastructure projects. Summary of the Invention

[0005] The purpose of the present invention is to provide a multifunctional storage box for power logistics infrastructure projects to solve the problems raised in the above background art.

The power conversion device and the power protection device contain tightly packed components. Once they are damaged by collision, the storage box housing, the power conversion device, and the power protection device will not be able to be used normally. Therefore, they are clamped and limited by the clamping and fixing device.

An equally wide moving chute is formed between the plurality of limiting top plates. There are two layers on the top of the storage box housing, namely the storage box top plate and the protective top layer. A plurality of symmetrically distributed limiting top plates are provided in the middle of the storage box top plate, and the limiting top plates are fixed to the bottom wall of the protective top layer through a plurality of limiting connecting top columns, so that an equally wide moving chute is formed between two adjacent limiting top plates, and the stability of the limiting top plates is relatively high. Moreover, between the plurality of limiting top plates, the storage box top plate and the protective top layer, an insulating layer can also be formed to reduce the temperature inside the storage box housing.

A lengthened connecting rod is provided at the bottom of the second connecting bearing ring, and the bottom end of the lengthened connecting rod is connected with the top end of the height adjustment rod; when the rotatable support disk rotates, the number of rotation circles can be offset through the second connecting bearing ring, so that the second connecting bearing ring and the lengthened connecting rod are in a stationary state.

[0012] Preferably, a triple connecting column is provided in the middle of the top end of the protective outer cylinder. A gear ring column is provided on the top wall of the rotatable support disk. A rotating inner gear is rotatably connected through a bearing inside the inner circle of the gear ring column on the top of the rotatable support disk. Among them, a rotating inner motor is provided on the top of the rotating inner gear. When the rotating inner motor operates, the output shaft of the rotating inner motor can drive the rotating inner gear to rotate together. The rotating inner gear is meshed with the gear ring column, so the rotating inner gear can drive the gear ring column to rotate together. The gear ring column is welded to the rotatable support disk, so when the gear ring column rotates, it can drive the rotatable support disk to rotate together.

[0013] Preferably, four pairs of pulley connection seats are provided on the bottom wall of the rotatable support disk.

The pulley connection seat is welded to the bottom wall of the rotatable support disk. When the rotatable support disk rotates, multiple pulley connection seats on the bottom wall of the rotatable support disk rotate together.

When the pulley power motor operates, the four moving pulleys can move forward in the same direction. The movement is more labor-saving, rapid, and stable.

[0014] Preferably, the key adjustment mechanism includes a key rotation motor, which is located at the position of the bottom side wall of the connecting vertical rod. The output shaft of the key rotation motor is connected to a linkage disk in the direction. One end of the linkage disk is connected to a linkage outer ring. At least two arc-shaped clamping blocks are connected to the inner wall of the linkage outer ring through a clamping key rod. When the key adjustment mechanism moves to a position close to the adjustment knob through the displacement adjustment mechanism, the linkage outer ring is sleeved on the outer ring of the adjustment knob, and then the clamping key rod is operated, so that the clamping key rod operates simultaneously, driving the arc-shaped clamping blocks to move, so that the multiple arc-shaped clamping blocks clamp and fix the adjustment knob. At this time, the key rotation motor is operated, so that the output shaft of the key rotation motor drives the linkage disk and the linkage outer ring to rotate together, and the adjustment knob clamped by the arc-shaped clamping blocks can be rotated together, thus achieving the effect of automatically rotating the adjustment knob.

[0015] Preferably, a motor limit base is provided at the bottom of the key rotation motor. A second anti-collision camera is provided on the bottom wall of one side of the motor limit base. A key adjustment telescopic column is provided on the side wall of the motor limit base, and the motor limit base is connected to the side wall of the connecting vertical rod through the key adjustment telescopic column. The key adjustment telescopic column can achieve the effect of integrally moving the motor limit base and the linkage outer ring, further improving the flexibility.

[0016] Preferably, rubber keys for pressing buttons are provided on the side walls of the arc-shaped clamping blocks. The length of the rubber keys for pressing buttons is greater than two centimeters. When automatic rotation of the adjustment knob is required, the arc-shaped clamping blocks can be used to clamp and fix for driving rotation. When the adjustment button needs to be switched, only the rubber keys for pressing buttons and the button adjustment telescopic column are needed. After the button adjustment telescopic column moves, the surface of the rubber key for pressing buttons first contacts the surface of the adjustment button. At this time, the button adjustment telescopic column can be continuously operated, so that the button adjustment telescopic column drives the rubber key for pressing buttons to move towards the adjustment button. The rubber key for pressing buttons exerts a force on the adjustment button, and then the effect of switching the adjustment button can be achieved. Moreover, the material of the rubber key for pressing buttons is rubber, which will not damage the adjustment button.

A plurality of symmetrically arranged limiting inner screw holes are formed on the surface of the limiting inner plates; the limiting inner screw holes are threaded holes.

[0018] Preferably, the clamping and fixing device includes an L-shaped limiting seat. One side of the L-shaped limiting seat is rotatably connected to a limiting screw through a limiting bearing ring, and the limiting screw is used in cooperation with the limiting inner screw hole. When the clamping and fixing device needs to be used, only the limiting screw on one side of the clamping and fixing device needs to be aligned with the position of the limiting inner screw hole, and the limiting bearing ring is rotated, so that the limiting screw rotates together with the limiting bearing ring, and the limiting screw is threadedly rotated and fixed with the limiting inner screw hole.

[0019] Preferably, a storage side groove is formed on the surface of the L-shaped limiting seat. A transverse connecting block is movably connected in the storage side groove. A clamping side plate is provided on one side of the transverse connecting block. The other side of the transverse connecting block is connected to a clamping telescopic inner rod, and the clamping telescopic inner rod is located at the position of the storage side groove; the clamping and fixing device can adaptively adjust the width according to the widths of the power conversion device and the power protection device to achieve a clamping effect. The clamping telescopic inner rod can be operated to drive the clamping side plate to move together. The limiting protrusion moves in the limiting track, which can achieve the effect of increasing stability. Then, the distance between the clamping side plate and the end of the L-shaped limiting seat is changed, and the flexibility is relatively high, achieving the effect of clamping power conversion devices of different sizes.

[0020] Preferably, limiting protrusions are symmetrically arranged at the top and bottom of the transverse connection block. Limiting tracks are provided on the top wall and bottom wall of the storage side groove, and the limiting protrusions are located within the limiting tracks. The distance between the end of the L-shaped limiting seat and the clamping side plate is greater than the widths of the power conversion device and the power protection device respectively. Protective rubber layers are provided on the opposite surfaces of the end of the L-shaped limiting seat and the clamping side plate. The protective rubber layers on the clamping side plate and the end of the L-shaped limiting seat can reduce friction and damage to the surface of the power conversion device. Compared with fixing the power conversion device and the power protection device with ropes, the overall clamping and fixing device is more stable, not easy to shake, firm during fixing, convenient to operate, and can ensure a more significant gap between the power conversion device, the power protection device and the inner wall of the storage box shell, will not trip staff, and is more convenient to use.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

Power personnel can realize remote operation control through the automatic operation component, improving flexibility while ensuring the normal operation of the storage box.

[0023] Multiple arc-shaped clamping blocks can clamp the adjustment knob. After it is clamped and fixed, the adjustment knob, the arc-shaped clamping blocks, and the linkage disc can all be rotated by the key rotation motor. It is not only convenient to use, but also the parts used are relatively common, and it is easy to control the cost. Moreover, it can be used in other fields and other equipment. The surface of the arc-shaped clamping block is provided with a key pressing rubber key. The key pressing rubber key can realize the opening and closing of the button as it moves with the key adjustment telescopic column, and the overall functionality is strong and the degree of automation is high.

[0024] The clamping and fixing device can firmly fix the power equipment in the storage box. At the same time, the clamping and fixing device is suitable for power equipment of various sizes. After the power equipment is placed in the storage box, the clamping and fixing device can clamp the power equipment, allowing the power equipment to be clamped by the clamping side plate and the L-shaped limiting seat, and then the clamping and fixing device is fixed to the inner wall of the storage box, so that multiple power equipment are fixed in the storage box through the clamping and fixing device. The whole is relatively stable, and at the same time, it will not damage the paint surface of the power equipment. The volume of the clamping and fixing device is large, and the fixed height can also be changed according to needs.

The inner wall of the linkage outer ring 610 is connected with at least two arc-shaped clamping blocks 612 through a clamping key rod 609. When the key adjustment mechanism 601 moves to a position close to the adjustment knob 32 through the displacement adjustment mechanism 630, the linkage outer ring 610 is sleeved on the outer ring of the adjustment knob 32, and then the clamping key rod 609 is operated, so that the clamping key rod 609 operates simultaneously, driving the arc-shaped clamping blocks 612 to move, and enabling the multiple arc-shaped clamping blocks 612 to clamp and fix the adjustment knob 32. At this time, the key rotation motor 607 is operated, so that the output shaft of the key rotation motor 607 drives the linkage disk 608 and the linkage outer ring 610 to rotate together, and the adjustment knob 32 clamped by the arc-shaped clamping blocks 612 can be rotated together, thus achieving the effect of automatically rotating the adjustment knob 32.

The length of the button-pressing rubber keys 611 is greater than two centimeters. When it is necessary to automatically rotate and adjust the knob 32, it can be clamped and fixed by the arc-shaped clamping blocks 612 to drive the rotation. And when it is necessary to switch the adjustment button 31, only the button-pressing rubber keys 611 and the button-adjusting telescopic column 606 are needed. When the button-adjusting telescopic column 606 moves, the surface of the button-pressing rubber key 611 first contacts the surface of the adjustment button 31. At this time, the button-adjusting telescopic column 606 can be continuously operated, so that the button-adjusting telescopic column 606 drives the button-pressing rubber key 611 to move in the direction of the adjustment button 31.
