Description

Technical Field

[0001] This invention belongs to the technical field of electric meter box transportation, and specifically relates to a protective device for the production and operation of electric meter boxes. Background Technology

[0002] As the core carrier of electricity metering equipment, the meter box is manufactured using a resin-based composite material system, mainly comprising four basic materials: acrylonitrile-butadiene-styrene (ABS) engineering plastics, transparent polycarbonate (PC) materials, bulk molding compound (DMC), and sheet molding compound (SMC). These materials are manufactured through injection molding and hot pressing processes. In the industrial production process, the assembled meter boxes need to be transported to the terminal installation area. Because multiple sets of precision electrical connection components are pre-installed inside the box, special requirements are placed on the transportation protection system—a protective system with anti-tipping, impact resistance, and environmental isolation functions is necessary.

[0003] Current transport protection solutions mainly employ a rigid container with a binding strap fixing structure. This technology has significant application drawbacks: First, in bulk transport scenarios, operators need to perform complex spatial arrangement and multi-point binding operations, which takes a lot of time. Furthermore, disassembly requires the complete removal of all restraint devices. When unloading a single meter box in different installation areas, it may cause all the meter boxes to loosen their restraints, requiring staff to re-bind them, which severely restricts loading and unloading efficiency. Second, when the transport environment has high humidity, such as in typical high-humidity conditions like mountainous areas and coastal areas, existing containers lack an active dehumidification mechanism. The condensation effect caused by the temperature difference between the inside and outside of the container can cause moisture to penetrate to the electrical component connections, leading to equipment damage and reliability degradation, resulting in significant cost losses. In response, this design proposes a protective device for the production and operation of electric meter boxes to improve upon the aforementioned technical shortcomings. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a protection device for the production and operation of electric meter boxes, thereby resolving the issues raised in the background section.

The outer wall of one end of each second retaining shaft is inserted through the inner wall of each fixing piece. A through groove is provided on one side of the outer wall of each sleeve. A U-shaped fixing frame is rotatably connected at the middle position of the outer wall of each connecting rod. A third limiting slide groove is provided on one side of the inner wall of each sleeve, and the outer wall of one end of each second retaining shaft is slidably connected to the inner wall of each third limiting slide groove.

[0012] Preferably, the back of the transfer compartment is provided with multiple slots at equal intervals. A fixing plate is fixedly provided above each slot on the back of the transfer compartment. A pin is inserted and connected to the bottom of each fixing plate. A third spring is fixedly provided between the bottom of each fixing plate and the middle position of each pin. A handle is fixedly connected to the top of each pin through the top of each fixing plate. Second locking holes are provided on the upper and lower sides of each U-shaped fixing frame and on the upper and lower sides of each slot.

A rotary lock cylinder is installed at the upper edge on the other side of each protective compartment door.

[0014] The technical effects and advantages of this invention are as follows: 1. This invention, through the establishment of a meter box transfer protection mechanism, allows for the transfer and unloading of meter boxes. By pulling out support frames from the side of the transfer compartment, each support frame is separated by a partition, allowing meter boxes to be placed on both sides of the inner wall of the support frame for separate protection against impact and wear. Simultaneously, rotating the support bar rotates the limiting cylinder to both sides of the meter box, compressing the protective pad to compress the second spring and thus securing the meter box. The limiting cylinder's position is fixed by engaging the first locking shaft with the first locking hole. During transfer, the support frame carrying the meter box is installed inside the transfer compartment, ensuring the stability of the meter box. Qualitatively, when unloading and installing designated meter boxes in different areas, it is only necessary to open the loading and unloading slot on the side where the designated meter box is installed, pull out the support frame in that area to expose it, and then remove the meter box at the top. This design eliminates the need for staff to perform complex spatial arrangements and multi-point binding when transporting and protecting the meter box. The support frame design allows staff to easily pull out the support frame from the side of the transport compartment to achieve rapid loading and unloading of the meter box. Furthermore, through the design of the limiting cylinder, the first locking shaft, and the protective pad, the meter box is effectively fixed during the transport process, avoiding damage caused by bumps or impacts. 2. This invention, by incorporating a moisture-proof component, powers a fan via a built-in battery when transporting the meter box in humid conditions. Simultaneously, airflow is introduced into the ventilation duct via an external duct and discharged through an outlet pipe connected to the bottom of the ventilation duct. This maintains a relatively dry environment inside the transfer compartment. Furthermore, the outlet pipe is angled inwards towards the support frame, directing airflow towards the meter box and preventing moisture from seeping in and damaging circuit components. This invention is suitable for high-humidity environments such as mountainous and coastal areas, improving the meter box's environmental adaptability during transport and reducing losses caused by environmental factors. 3. This invention, through the setting of a fixing mechanism, allows the meter box to be installed inside the transfer chamber. By pushing the U-shaped fixing frame, the connecting rod extends and pushes the second locking shaft into the fixing plate. Simultaneously, pulling the handle raises the pin. When the U-shaped fixing frame is fully inserted into the slot, releasing the handle allows the pin to be stably inserted into the second locking hole on the U-shaped fixing frame and the slot under the action of the third spring, thus maintaining the stability of the fixing mechanism. By locking the fixing plate, the support frame is stably fixed inside the transfer chamber. Moreover, all fixing operations are performed outside the transfer chamber, simplifying the operation process and improving work efficiency.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides, for example Figure 1-11 The device shown is a protective device for the production and transfer of an electric meter box, including a transfer chamber 1. The upper end of the transfer chamber 1 is provided with an electric meter box transfer protection mechanism 2, a fixing mechanism 8, and a moisture-proof component 13. The electric meter box transfer protection mechanism 2 and the moisture-proof component 13 are both installed inside the transfer chamber 1, and the fixing mechanism 8 is installed on the back of the transfer chamber 1. The meter box transfer protection mechanism 2 includes multiple support frames 201 that are equidistantly installed inside the transfer compartment 1. A partition 202 is fixedly installed in the middle of the inner wall of each support frame 201. Support bars 203 are rotatably connected to both ends of the inner wall of each support frame 201 and both ends of both sides of each partition 202. A limit cylinder 204 is fixedly connected to one end of every two support bars 203. A first limit groove 205 is provided on one side of each limit cylinder 204. First retaining shafts 206 are inserted through both ends of the inner wall of each limit cylinder 204. The outer wall of one end of every two first retaining shafts 206 is slidably connected to the inner walls of both ends of one of the first limit grooves 205. A first spring 207 is fixedly installed in the middle of the inner wall of each limit cylinder 204. Both ends of each first spring 207 are fixedly connected to one end of each first retaining shaft 206. Multiple second springs 208 are fixedly installed on one side of each limit cylinder 204. Protective pads 209 are provided on the outer edge of one side of 204, and one side of each protective pad 209 is fixedly connected to one end of multiple second springs 208. A connecting block 210 is fixedly provided on one side of each first locking shaft 206. First locking holes 211 are opened at both ends of the inner wall of each support frame 201 and at both ends of each partition 202. The outer wall of one end of each first locking shaft 206 is inserted and connected to the inner wall of each first locking hole 211. The conventional size of the meter box is 600mm×400mm×150mm. The height and front and rear width of the support frame 201 in this design scheme are specifically designed according to the conventional size of the meter box, so that a conventional size meter box can be placed on both sides of the partition 202. When the limiting cylinder 204 is locked in the first locking hole 211 by the first locking shaft 206, the distance between the protective pads 209 on both sides can be maintained between 38mm and 44mm when the spring is compressed. Moisture-proof component 13 includes two ventilation pipes 1301 installed on the top of transfer chamber 1, multiple air outlet pipes 1302, two external air ducts 1303, and two fans 1304, and the external air ducts 1303 are as shown in the instruction manual. Figure 1 and 10 As shown, it is curved and the open end faces downwards, so that rainwater is not easy to enter the transfer chamber 1 from the external air duct 1303 when it is transferred in rainy weather. In use, the transfer compartment 1 is installed on the transfer truck and secured. After opening all the protective doors 14 on the transfer compartment 1, the support frame 201 is pulled out through the loading and unloading slot 11, exposing the area where the meter box is loaded. Then, the operator pinches the two connecting blocks 210 on the outside of each limiting cylinder 204 and squeezes them together, causing the first locking shaft 206 in the inner wall of the limiting cylinder 204 to retract inside the limiting cylinder 204, disengaging it from the first locking hole 211. At this time, the support bar 203 can be rotated. The limiting cylinder 204 is rotated and lowered. After the limiting cylinder 204 is lowered, the operator can place the meter box on both sides of the partition 202 on the inner wall of each support frame 201. Then, the support bar 203 is rotated again to make the limiting cylinder 204 rotate and lift, pressing against both sides of the meter box. The protective pad 209 on the outer surface of the limiting cylinder 204 contacts and presses against it. During the pressing, the protective pad 209 compresses the second spring 208 to buffer the pressure and prevent excessive pressure from damaging the outer wall of the meter box. When the 09 is pressed against both sides of the meter box, the limiting cylinder 204 is pushed so that the first locking shafts 206 at both ends compress the first springs 207 inside and squeeze them into the first locking holes 211 on both sides of the support frame 201 and the partition 202, thereby fixing the meter box. Finally, the support frame 201 is slid into the transfer chamber 1 and the protective chamber door 14 is closed. During unloading, when unloading and installing designated meter boxes in different installation areas, it is only necessary to open the corresponding protective chamber door 14 and slide out the support frame 201. By rotating and lowering the limiting cylinder 204 during loading, the designated meter box can be unloaded and installed. There is no need to release all the meter boxes. This transfer protection device does not require the staff to make complicated spatial arrangements when loading and unloading meter boxes, making unloading more convenient. It can be loaded and unloaded individually. When transporting in some high humidity environments, the moisture-proof component 13 exhausts the moisture inside the transfer chamber 1 to keep it dry and prevent the meter box from being damaged by moisture, thus reducing the risk of cost loss.

[0021] Furthermore, as per the instruction manual... Figure 9-10 As shown, two ventilation pipes 1301 are fixedly installed on both sides of the top of the transfer chamber 1. Each air outlet pipe 1302 is installed at equal intervals at the bottom of the two ventilation pipes 1301, and one end of each air outlet pipe 1302 is inserted and connected to the inner wall of the transfer chamber 1. Each air outlet pipe 1302 is as shown in the attached instruction manual. Figure 9 The air outlets are all inclined toward the inside of the support frame 201 installed inside the transfer chamber 1, and are arc-shaped as shown.

[0022] Two external air ducts 1303 are respectively installed at the upper edges of both ends of the side of the transfer chamber 1, and the inner walls of one end of the two external air ducts 1303 and the inner walls of one end of each air outlet duct 1302 are respectively connected to the inner walls of the two ventilation ducts 1301. Two fans 1304 are respectively installed at the edges of the inner walls of the two external air ducts 1303, and the transfer chamber 1 is equipped with a built-in battery. The two fans 1304 are electrically connected to the built-in battery. When the transfer chamber 1 transports the meter box to mountainous areas and other areas... In humid areas, during transportation, the built-in battery powers the fan 1304, starting the fan 1304 and connecting it to the ventilation pipe 1301 via the external air duct 1303. This directs airflow into the ventilation pipe 1301, while the ventilation pipe 1301 blows airflow through each outlet pipe 1302 towards the installation area of ​​the internal support frame 201 of the transfer chamber 1, achieving internal drying, reducing the probability of moisture in the transfer chamber 1, and improving the protection of the internal components of the meter box.

[0023] Furthermore, as per the instruction manual... Figure 3 As shown, each support frame 201 has a second limiting groove 212 at the bottom of its inner wall on both sides of each partition 202. Each second limiting groove 212 has a clamping plate 213 slidably connected to both ends of its inner wall. The clamping plate 213 is slidably installed in the inner wall of the second limiting groove 212 and is located at the bottom of the inner wall of the support frame 201.

[0024] Each second limiting slide groove 212 has a bidirectional screw 214 rotatably connected to its inner wall. The outer walls of both ends of each bidirectional screw 214 are threaded to the inner wall of each clamping plate 213. One end of each pair of bidirectional screws 214 located on the same support frame 201 is fixedly connected to each other. When the meter box is placed inside the support frame 201, it is pressed and fixed on both sides by the limiting cylinder 204 and the protective pad 209. Then, the external movable sleeve is inserted into the docking sleeve shaft 4 on one side of the support frame 201. After rotating the docking sleeve shaft 4, the two bidirectional screws 214 on the inner wall of the support frame 201 are fixed at their ends. After rotating the docking sleeve shaft 4, the two bidirectional screws 214 rotate together and move the clamping plates 213 on both sides of the partition 202 to each other until the lower edges of the meter box installed on both sides of the partition 202 are pressed to achieve a reinforcement effect. This makes it more stable during transportation and less prone to large-scale shaking and impact from bumps, thus avoiding collisions and wear. Each support frame 201 has a first groove 3 at the lower edge of both sides of its inner wall and at the lower edge of both sides of each partition 202. The outer wall of each clamp 213 is inserted and connected to the inner wall of each first groove 3. Each support frame 201 has a connecting sleeve shaft 4 inserted and connected to one side. One end of each connecting sleeve shaft 4 passes through the inner wall of one side of each support frame 201 and is fixedly connected to one end of one double-acting screw 214. When not in use, the clamp 213 is rotated and moved into the first groove 3 on both sides by the double-acting screw 214, so that its side is flush with the side of the support frame 201 and the partition 202, so as not to obstruct the placement and installation of the meter box. Furthermore, as per the instruction manual... Figure 5 As shown, each support frame 201 has a fixing plate 5 fixed at both ends on the other side, and rollers 6 are rotatably connected to both ends on one side of the bottom of each support frame 201. An L-shaped clamping plate 7 is fixed at the middle position on one side of the bottom of each support frame 201. When loading and unloading the meter box, the support frame 201 is pulled out from the loading and unloading slot 11. However, the support frame 201 is not completely pulled out of the loading and unloading slot, and its side is still located inside the loading and unloading slot 11. The L-shaped clamping plate 7 at the bottom of the support frame 201... During the sliding process in the second groove 9, as the support frame 201 is pulled out of the loading and unloading groove 11, its outer wall is locked into the limiting groove 10, thereby locking the support frame 201 so that it will not tilt and fall due to the pressure of the weight of the meter box when loading and unloading the meter box. At the same time, when the meter box is loaded and unloaded, when the support frame 201 is pulled out in the loading and unloading groove 11, the roller 6 at the bottom of the support frame 201 rolls in the second groove 9, making the pulling out smoother. Furthermore, as per the instruction manual... Figure 6-8 As shown, the fixing mechanism 8 includes multiple sleeves 801 fixed at equal intervals to the back of the transfer chamber 1. A second retaining shaft 802 is inserted through the inner wall of each sleeve 801, and a connecting rod 803 is rotatably connected between every two second retaining shafts 802. The outer wall of one end of each second retaining shaft 802 is inserted through the inner wall of each fixing piece 5. A through groove 804 is provided on one side of the outer wall of each sleeve 801. A U-shaped fixing bracket 805 is rotatably connected to the middle position of the outer wall of each connecting rod 803. A first retaining shaft 804 is provided on one side of the inner wall of each sleeve 801. The sleeve 801 has three limiting grooves 806, and the outer wall of one end of each second locking shaft 802 is slidably connected to the inner wall of each third limiting groove 806. A through groove 804 is provided at one end of the sleeve 801 to facilitate the buffering of the connecting rod 803 when it is folded, so as to avoid the connecting rod 803 from colliding with the inner wall of the sleeve 801 and causing motion interference. The second locking shaft 802 slides in the sleeve 801 through the sliding limit of the third limiting groove 806 on one side of the inner wall of the sleeve 801, so that the second locking shaft 802 cannot be disengaged from the sleeve 801.

[0025] Multiple slots 807 are fixedly provided at equal intervals on the back of the transfer compartment 1. A fixing plate 808 is fixedly provided above each slot 807 on the back of the transfer compartment 1. A pin 809 is inserted and connected to the bottom of each fixing plate 808. A third spring 810 is fixedly provided between the bottom of each fixing plate 808 and the middle position of each pin 809. A handle 811 is fixedly connected to the top of each pin 809 through the top of each fixing plate 808. The upper and lower sides of each U-shaped fixing bracket 805 and each slot are also fixedly provided. The upper and lower sides of 807 are provided with second locking holes 812, and the outer wall of one end of each pin 809 is respectively inserted and connected to the inner wall of four of the second locking holes 812. When the support frame 201 is loaded with the meter box and slidably stored in the transfer chamber 1 for transfer protection, two fixing plates 5 on one side of the support frame 201 move with it and pass through the connecting groove 12 on one side of the inner wall of the transfer chamber 1. The inserted fixing plates 5 are located on both sides of each set of fixing mechanisms 8. The staff can directly access the transfer chamber 1 from the outside through the connection groove 12 as shown in the instruction manual. Figure 7 Pushing the handle on one side of the U-shaped fixing bracket 805 moves the U-shaped fixing bracket 805 towards one side of the transfer chamber 1. Simultaneously, the connecting rod 803 extends, causing the second retaining shafts 802 inside the sleeves 801 on both sides to slide and extend until the second retaining shafts 802 at both ends engage with the inner walls of the fixing plates 5 on both sides. At the same time, one end of the U-shaped fixing bracket 805 also engages with the retaining groove 807 on the back of the transfer chamber 1. Then, pull the upper handle 811 to move the pin 809 upwards, as shown in the instruction manual. Figure 8 As shown, after the pin 809 is pulled up, the U-shaped fixing bracket 805 is pushed to continue to be inserted into the slot 807. After the two second locking holes 812 on the U-shaped fixing bracket 805 are aligned with the two second locking holes 812 on the slot 807, the handle 811 is released. Under the elastic action of the third spring 810, the pin 809 is inserted into the four corresponding second locking holes 812 below it, thereby fixing the positions of the second locking shafts 802 at both ends. The second locking shafts 802 are inserted into the fixing plate 5, thereby fixing the support frame 201 and preventing it from swaying left and right during transportation, which would cause the meter box inside to shake and fall. At the same time, the fixing mechanism 8 is easy to operate, and the staff can operate and fix it from outside the transfer chamber 1, which improves the convenience of using the device. Furthermore, as per the instruction manual... Figure 2 , 9As shown in Figure 11, multiple second grooves 9 are evenly spaced at the bottom of the inner wall of the transfer chamber 1. Each second groove 9 has a limiting groove 10 on one side of its inner wall. Multiple loading / unloading slots 11 are evenly spaced on one side of the transfer chamber 1. The outer wall of each support frame 201 is interlocked with the inner wall of each loading / unloading slot 11. Multiple connecting slots 12 are evenly spaced on the back of the transfer chamber 1. The outer wall of each fixing piece 5 is interlocked with the inner wall of each connecting slot 12. The outer wall of each L-shaped clamp 7 is interlocked with the inner wall of each limiting groove 10. A protective door 14 is hinged to the inner wall of each loading / unloading slot 11. Each protective door...
