Description

Technical Field

[0001] This invention relates to the technical field of metering and data acquisition equipment, specifically a multi-channel detection Internet of Things (IoT) metering and data acquisition device. Background Technology

[0002] Electricity meters are widely used in power systems as a type of electricity metering device. Each single-phase electricity meter has one live wire inlet and one live wire outlet. Both the inlet and outlet wires need to be connected to the corresponding internal components of the electricity meter via copper strips. Typically, one meter is used per household for electricity metering.

[0003] In existing technologies, the installation method of one meter per household is costly. In addition, when connecting the neutral and live wires to the electricity meter, one end of the neutral and live wires is usually inserted into the corresponding terminal block. The terminal block has a bolt inside, which is rotated downwards to fix the neutral and live wires. In a humid environment, the bolt is prone to rusting. At the same time, the bolt is prone to detaching from the terminal block during the rotation process, which can lead to the loss of bolt parts and affect the connection efficiency between the neutral or live wire and the electricity meter. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-channel detection IoT metering and acquisition device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-channel detection IoT metering and acquisition device includes a main body. A mounting groove is provided at one end of the top of the main body. Several evenly distributed terminal blocks are fixedly arranged in the mounting groove. An upper clamping plate is provided on the top of the terminal blocks. First slide rods are slidably sleeved inside both ends of the upper clamping plate. The first slide rods are fixedly arranged inside the terminal blocks. A return spring is sleeved on the outside of the first slide rods.

[0007] The top of the terminal block is provided with a clamping component. By operating the clamping component to move the upper clamping plate downward, the connecting wires inside the terminal block can be fixed.

[0008] The bottom of the terminal block is provided with a lower clamping plate, and both ends of the lower clamping plate are slidably fitted with second sliding rods. The second sliding rods are fixedly installed inside the terminal block. The upper clamping plate and the lower clamping plate have arc-shaped grooves on opposite sides. The terminal block is provided with an auxiliary component. When the clamping component moves the upper clamping plate downward, the auxiliary component pushes the lower clamping plate upward. The upper clamping plate and the lower clamping plate slide relative to each other at the same time to fix the connecting wire inside the terminal block.

[0009] The main body is internally provided with an adjustment component, which is used to operate the position of all adjusting clamping components, so that all clamping components can be reset, thereby causing all upper clamping plates to reset upward and no longer fix the connecting wires.

[0010] The clamping assembly includes a fixed rod fixedly mounted on the top of the terminal block. A sleeve is slidably fitted on the outside of the fixed rod. A clamping rod is rotatably fitted on the outside of the sleeve. A limit groove is formed at the end of the clamping rod away from the sleeve. Torsion springs are fitted on the outside of both ends of the sleeve. The main body has the same number of connecting rods as the terminal block inside. A limit rod that cooperates with the limit groove is fixedly mounted on one side of the connecting rod.

[0011] The auxiliary component consists of two first racks, two second racks, and two gears. The two first racks are fixedly disposed at both ends of the bottom of the upper clamping plate, and the two second racks are fixedly disposed at both ends of the top of the two lower clamping plates. The two gears are rotatably disposed between two adjacent first racks and second racks, and the gears mesh with the first racks and second racks.

[0012] As mentioned above: anti-slip pads are provided inside the arc-shaped grooves in the upper and lower clamping plates, and first grooves are provided at both ends of the upper clamping plate and both ends of the lower clamping plate, and the first grooves cooperate with the first and second racks.

[0013] Both the first rack and the second rack have slide bars fixedly installed on the side away from the gear, and the terminal block has a sliding groove inside that mates with the slide bars.

[0014] The top of the terminal block has a second groove, which cooperates with the clamping rod.

[0015] A handle is fixedly installed on the top of the clamping rod for the user to operate the clamping rod.

[0016] A protective cover is rotatably installed at one end of the main body near the mounting groove.

[0017] The adjusting assembly includes a threaded rod, the threaded rod having a number of movable blocks connected to its external thread as equal to the number of connecting rods. The side of the connecting rod away from the limiting rod is fixedly connected to the movable block. A protrusion is formed at the bottom of the movable block. Two crossbars are fixedly installed inside the main body, and a strip groove is formed between the two crossbars. The protrusion is located inside the strip groove.

[0018] Both ends of the threaded rod are rotatably equipped with mounting blocks, and the mounting blocks are fixedly connected to the main body by bolts.

[0019] Compared with the prior art, the beneficial effects of the present invention are: by setting a plurality of terminals, not less than eight, with the two terminals in the middle being the main port for live wire inlet and the main port for neutral wire inlet respectively, and the terminals on the other two sides being the branch ports for live wire outlet and the branch ports for neutral wire outlet respectively, the effect of one energy meter being able to detect electricity consumption through multiple channels is achieved, reducing production costs;

[0020] When fixing the neutral and live wires, the neutral and live wires are inserted into the corresponding terminals respectively. Then, by operating the clamping assembly, the upper clamping plate moves downward along the first slide bar. At this time, the return spring extends, and the upper clamping plate can fix the neutral or live wire, completing the quick connection between the main body and the neutral or live wire. This replaces the existing technology of using a bolt to fix the neutral and live wires, avoiding the problem of missing parts, and improving the connection efficiency between the neutral or live wire and the electricity meter.

[0021] With the help of the auxiliary components, when the upper clamping plate moves downward, the lower clamping plate moves relative to the upper clamping plate at the same time under the action of the auxiliary components, and clamps and fixes the neutral wire or live wire, thereby improving the firmness of the connection between the neutral wire or live wire and the main body.

[0022] With the adjustable components, when the main body is damaged and needs to be replaced, all neutral and live wires need to be separated from the main body. By operating the adjustable components, the positions of all clamping components can be adjusted at the same time, so that the top of the upper clamping plate is not under force. All the upper clamping plates move upward and reset under the action of the return spring, so as to simultaneously release the fixation of all neutral and live wires. The neutral and live wires are separated from the main body at the same time, eliminating the need for individual operation and making it convenient for staff to use. Attached Figure Description

[0034] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0035] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0036] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0037] Please see Figure 1-10In this embodiment of the invention, a multi-channel detection IoT metering and acquisition device includes a main body 1. One end of the top of the main body 1 is provided with an installation groove 2. Several evenly distributed terminal blocks 3 are fixedly arranged in the installation groove 2. A protective cover 17 is rotatably arranged at the end of the main body 1 near the installation groove 2. The protective cover 17 can protect all parts inside the installation groove 2 and prevent foreign objects from entering the installation groove 2. By opening the protective cover 17, the parts inside the installation groove 2 can be operated. The top of the terminal block 3 is provided with an upper clamping plate 4. The interior of both ends of the upper clamping plate 4 is slidably fitted with a first sliding rod 5. The first sliding rod 5 is fixedly arranged inside the terminal block 3. A return spring 6 is sleeved on the outside of the first sliding rod 5.

[0038] The top of the terminal block 3 is provided with a clamping component 7. By operating the clamping component 7, the upper clamping plate 4 can be moved downward, thereby fixing the connecting wires inside the terminal block 3.

[0039] The bottom of the terminal block 3 is provided with a lower clamping plate 8. Both ends of the lower clamping plate 8 are slidably fitted with second slide rods 9. The second slide rods 9 are fixedly installed inside the terminal block 3. The upper clamping plate 4 and the lower clamping plate 8 form arc-shaped grooves on opposite sides. The terminal block 3 is provided with an auxiliary component 10. When the pressing component 7 moves the upper clamping plate 4 downward, the auxiliary component 10 pushes the lower clamping plate 8 upward. The upper clamping plate 4 and the lower clamping plate 8 slide relative to each other at the same time to fix the connecting wire inside the terminal block 3.

[0040] The main body 1 is equipped with an adjustment component 11. The adjustment component 11 is used to operate the position of all clamping components 7, so that all clamping components 7 can be reset, thereby causing all upper clamping plates 4 to be reset upward and no longer fix the connecting wire.

[0041] There are multiple terminals 3, and no fewer than eight. The two terminals 3 in the middle are the main port for live wire inlet and the main port for neutral wire inlet, respectively. The terminals on the other two sides are the branch ports for live wire outlet and the branch ports for neutral wire outlet, respectively. This achieves the effect of one energy meter being able to detect multiple power consumption channels, thus reducing production costs.

[0042] When fixing the neutral wire and the live wire, insert the neutral wire and the live wire into the corresponding terminal block 3 respectively. Then, by operating the clamping component 7, the upper clamping plate 4 moves downward along the first slide bar 5. At this time, the return spring 6 extends, and the upper clamping plate 4 can fix the neutral wire or the live wire, completing the quick connection between the main body 1 and the neutral wire or the live wire. This replaces the method of fixing the neutral wire and the live wire with a bolt in the prior art, and will not cause the problem of missing parts. At the same time, it improves the connection efficiency between the neutral wire or the live wire and the electricity meter.

[0043] With the help of the auxiliary component 10, when the upper clamping plate 4 moves downward, the lower clamping plate 8 moves upward along the second slide bar 9 under the action of the auxiliary component 10. The lower clamping plate 8 and the upper clamping plate 4 move relative to each other at the same time, and clamp and fix the neutral wire or the live wire at the same time, which improves the firmness of the connection between the neutral wire or the live wire and the main body 1.

[0044] When the main body 1 is damaged and needs to be replaced, all neutral and live wires need to be separated from the main body 1 by adjusting the component 11. By operating the adjusting component 11, the position of all clamping components 7 can be adjusted at the same time, so that the top of the upper clamping plate 4 is not under force. All the upper clamping plates 4 move upward and reset under the action of the reset spring 6, so as to release the fixation of all neutral and live wires at the same time. The neutral and live wires are separated from the main body at the same time, without the need for operation one by one, which is convenient for the staff to use.

[0045] Please see Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 as well as Figure 10 The clamping assembly 7 includes a fixing rod 701 fixedly mounted on the top of the terminal block 3. A sleeve 702 is slidably sleeved on the outside of the fixing rod 701. A clamping rod 703 is rotatably sleeved on the outside of the sleeve 702. A limiting groove 704 is opened at the end of the clamping rod 703 away from the sleeve 702. Torsion springs 705 are sleeved on the outside of both ends of the sleeve 702. The main body 1 is provided with the same number of connecting rods 706 as the terminal block 3. A limiting rod 707 that cooperates with the limiting groove 704 is fixedly mounted on one side of the connecting rod 706.

[0046] The top of the terminal block 3 is provided with a second groove 15, which cooperates with the clamping rod 703;

[0047] A handle 16 is fixedly provided on the top of the clamping rod 703 for the user to operate the clamping rod 703, making it convenient for the user to operate;

[0048] When fixing the connecting wire inside the terminal block 3, the clamping rod 703 is rotated upwards towards one side of the clamping plate 4 using the handle 16. At this time, the torsion spring 705 deforms, and the clamping rod 703 rotates along the sleeve 702, so that the bottom end of the clamping rod 703 is located inside the second groove 15. The cross-section of the fixing rod 701 is rectangular, so that the sleeve 702 can only slide along the fixing rod 701 and will not rotate. When rotating the clamping rod 703, the clamping rod 703 will only rotate along the sleeve 702, thus ensuring the effectiveness of the torsion spring 705. As the clamping rod 703 moves downwards, the pressure... The clamping rod 703 applies pressure to the upper clamping plate 4, causing the upper clamping plate 4 to move downwards. When the clamping rod 703 rotates to its limit position, the sleeve 702 and the clamping rod 703 slide towards the side close to the connecting rod 706. The sleeve 702 slides outside the fixed rod 701 until the limiting rod 707 is inserted into the limiting groove 704, limiting the position of the clamping rod 703. This ensures that the clamping rod 703 always acts on the upper clamping plate 4. Pulling the clamping rod 703 causes the limiting rod 707 to disengage from the limiting groove 704. The clamping rod 703 can then automatically reset under the torsion spring 705, facilitating user operation.

[0049] Please see Figures 7-10 The auxiliary component 10 consists of two first racks 1001, two second racks 1002, and two gears 1003. The two first racks 1001 are fixedly disposed at both ends of the bottom of the upper clamping plate 4, and the two second racks 1002 are fixedly disposed at both ends of the top of the two lower clamping plates 8. The two gears 1003 are rotatably disposed between two adjacent first racks 1001 and second racks 1002, and the gears 1003 mesh with the first racks 1001 and the second racks 1002.

[0050] Slide bars 13 are fixedly provided on the side of the first rack 1001 and the second rack 1002 away from the gear 1003. The terminal block 3 has a groove 14 inside that cooperates with the slide bar 13. When the first rack 1001 and the second rack 1002 move up and down, the slide bar 13 is driven to slide along the groove 14, thereby improving the stability of the first rack 1001 and the second rack 1002 when they move up and down, ensuring the meshing effect between the first rack 1001, the second rack 1002 and the gear 1003, and enabling the auxiliary component 10 to operate normally.

[0051] When the upper clamping plate 4 moves the first rack 1001 downward, the second rack 1002 moves the lower clamping plate 8 upward under the action of the gear 1003. The upper clamping plate 4 and the lower clamping plate 8 move relative to each other at the same time, thereby achieving the effect of clamping and fixing the live wire and the neutral wire at the same time. When the upper clamping plate 4 moves upward, the first rack 1001 moves upward, and the second rack 1002 moves the lower clamping plate 8 downward. The upper clamping plate 4 and the lower clamping plate 8 are simultaneously disengaged from the neutral wire and the live wire. Under the action of the auxiliary component 10, the clamping component 7 can operate the upper clamping plate 4 and the lower clamping plate 8 at the same time. The lower clamping plate 8 can move synchronously with the upper clamping plate 4. The user does not need to operate the lower clamping plate 8 separately, which provides certain convenience for the user.

[0052] Anti-slip pads are provided inside the arc-shaped grooves in the upper clamping plate 4 and the lower clamping plate 8. First grooves 12 are provided at both ends of the upper clamping plate 4 and the lower clamping plate 8, and the first grooves 12 cooperate with the first rack 1001 and the second rack 1002.

[0053] By providing anti-slip pads inside the arc-shaped grooves in the upper clamping plate 4 and the lower clamping plate 8, the clamping effect of the upper clamping plate 4 and the lower clamping plate 8 on the live wire and the neutral wire is improved, and the live wire and the neutral wire are not easy to detach from the upper clamping plate 4 and the lower clamping plate 8. Through the first groove 12, the first rack 1001 and the second rack 1002 can pass through the first groove 12 to continue moving during the up and down movement, so as to avoid the upper clamping plate 4 and the lower clamping plate 8 affecting the movement of the first rack 1001 and the second rack 1002.

[0054] Please see Figure 1 and Figure 3 The adjusting component 11 includes a threaded rod 1101, and the threaded rod 1101 is externally threaded with a number of movable blocks 1102 equal to the number of connecting rods 706. The side of the connecting rod 706 away from the limiting rod 707 is fixedly connected to the movable block 1102. A protrusion 1103 is formed at the bottom of the movable block 1102. Two crossbars 1104 are fixedly arranged inside the main body 1. A strip groove is formed between the two crossbars 1104. The protrusion 1103 is disposed inside the strip groove.

[0055] Both ends of the threaded rod 1101 are rotatably equipped with mounting blocks, and the mounting blocks are fixedly connected to the main body 1 by bolts;

[0056] When the main body 1 is damaged and needs to be replaced, all neutral and live wires need to be separated from the main body 1. At this time, the threaded rod 1101 can be rotated. Under the action of the protrusion 1103 and the slot, the moving block 1102 is limited. The moving block 1102 on the threaded rod 1101 can then drive all the connecting rods 706 and the limiting rods 707 to slide, moving the connecting rods 706 and the limiting rods 707 away from the pressing rod 703, so that the limiting rod 707 is disengaged from the limiting groove 704. At this time, the pressing rod 703 is reset under the action of the torsion spring 705, thereby preventing the upper clamping plate 4 and the lower clamping plate 8 from fixing the neutral and live wires, thus achieving the simultaneous removal of all neutral and live wires. The effect of separating the thread from the main body 1 is achieved. At the same time, since both ends of the threaded rod 1101 are fixed to the main body 1 through the cooperation of the mounting block and bolts, and the end of the main body 1 is provided with a mounting groove that cooperates with the mounting block, when the threaded rod 1101 rusts, the bolts between the mounting block and the main body 1 are removed, so that the threaded rod 1101 can be disassembled and separated from the main body 1. The user can then replace the threaded rod 1101. The new threaded rod 1101 is then placed into the main body 1 from top to bottom. After the mounting block and the mounting groove are aligned, the protrusion 1103 at the bottom of the moving block 1102 is inserted into the strip groove between the two crossbars 1104. Then the adjustment component 11 can be reused.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0058] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
