Detailed Implementation

[0025] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] See also Figures 1-5 This utility model provides a voltage signal remote data acquisition device, including a voltage data acquisition unit 1, on which a communication antenna 2 is provided.

[0027] Voltage data acquisition device 1 is used to collect voltage signal data during the operation of electromechanical equipment. Since voltage data acquisition device 1 is a publicly available and mature technology, it will not be described in detail here. Communication antenna 2 can provide wireless communication capability for voltage data acquisition device 1.

[0028] In this embodiment: A wiring groove 3 is provided on one side of the voltage data acquisition device 1. A wire pressing block 4 and a core pressing block 5 are provided in the wiring groove 3. The number of wire pressing blocks 4 and core pressing blocks 5 is a pair.

[0029] The wire clamping block 4 provides wire sheath clamping for the wires connected to the voltage data acquisition device 1, while the core clamping block 5 provides wire core clamping for the wires connected to the voltage data acquisition device 1. In this application, the wire clamping block 4 can be made of insulating material, while the core clamping block 5 can be made of metal conductor material.

[0030] In this embodiment: the wire pressing block 4 is provided with a wire sheath groove 41, and the core pressing block 5 is provided with a core groove 51. The size of the core groove 51 is smaller than the size of the wire sheath groove 41.

[0031] The advantage of the size design is that, since the wire sheath size is larger than the wire core size, the wire clamping block 4 can simultaneously clamp the wire sheath and core through the wire sheath groove 41 and the core clamping block 5 through the wire core groove 51.

[0032] In this embodiment: the wire clamping block 4 is located near the opening of the wiring trough 3. The wire clamping block 4 is located on one side of the clamping core block 5. The wire clamping block 4 and the clamping core block 5 at the bottom are both fixedly connected in the wiring trough 3. The width of the wire clamping block 4 and the clamping core block 5 at the bottom is the same as the width of the wiring trough 3, while the width of the wire clamping block 4 and the clamping core block 5 at the top is smaller than the width of the wiring trough 3.

[0033] The advantage of using different widths for the upper and lower distributed pressure blocks 4 and pressure core blocks 5 is that, since the pressure blocks 4 and pressure core blocks 5 at the bottom are fixed to the wiring trough 3, the matching width can avoid connection gaps. On the other hand, since the pressure blocks 4 and pressure core blocks 5 at the top are movable, the width is smaller than that of the wiring trough 3, which can reduce the resistance of movement friction.

[0034] In this embodiment: A lifting assembly 6 is provided on the voltage data acquisition unit 1. The lifting assembly 6 extends into the voltage data acquisition unit 1. A lifting groove 8 connected to the wiring groove 3 is provided inside the voltage data acquisition unit 1. The lifting assembly 6 includes a screw 61, which is threadedly connected to the voltage data acquisition unit 1. One end of the screw 61 extends into the lifting groove 8. A lifting plate 62 is rotatably connected to the bottom end of the screw 61. The pressure block 4 and the pressure core block 5 located at the top are both fixedly connected to the bottom of the lifting plate 62.

[0035] In use, by using a tool to rotate the screw 61, the threaded movement of the screw 61 on the voltage data acquisition unit 1 can cause the lifting plate 62 to move up and down in the wiring trough 3 and the lifting groove 8. In this way, the lifting plate 62 can drive the top pressure block 4 and the core pressure block 5 to approach the bottom pressure block 4 and the core pressure block 5, so as to press the sheath and core of the wire inserted in the wiring trough 3.

[0036] In this embodiment: a sealing gasket 10 is sleeved on the screw 61, and the sealing gasket 10 is in active contact with the upper surface of the voltage data acquisition device 1.

[0037] After the screw 61 is fully tightened, the sealing gasket 10 can be pressed and fixed on the top of the voltage data acquisition unit 1, so that the sealing gasket 10 can increase the sealing performance of the screw 61 at the screw groove position.

[0038] In this embodiment: the lifting assembly 6 is provided with a sealing baffle 7 for sealing the wiring trough 3. The sealing baffle 7 can be made of rubber. The sealing baffle 7 is fixedly connected to one side of the lifting plate 62. The inner wall of the wiring trough 3 is provided with a sliding groove 9. The sliding groove 9 extends to the lifting groove 8. The sealing baffle 7 is slidably connected in the sliding groove 9. When the sealing baffle 7 slides to the inner bottom of the sliding groove 9, the sealing baffle 7 is in close contact with the side of a pair of wire pressing blocks 4.

[0039] During use, while the wire clamping blocks 4 and core clamping blocks 5 are distributed in pairs to clamp the wires, the lifting plate 62 also moves the sealing baffle 7 in the sliding groove 9. At this time, the sealing baffle 7 can provide a moving guide for the lifting plate 62. Since the sealing baffle 7 is made of rubber, the sliding connection between the sealing baffle 7 and the sliding groove 9 has a certain tightness. After the wire clamping blocks 4 are clamped on the wires, the sealing baffle 7 will also press against the wire sheath. At the same time, the side of the sealing baffle 7 will be in close contact with the pair of wire clamping blocks 4. In this way, the sealing baffle 7 can seal the local position of the wiring trough 3 and block the connection of the pair of wire clamping blocks 4. Thus, the groove opening of the wiring trough 3 can achieve a sealing effect to prevent dust accumulation and water ingress at the wire core position.

[0040] In this embodiment: a wire groove 71 is provided on the sealing baffle 7, and the wire groove 71 is arranged in a "door" shape.

[0041] The groove size at the top of the second wire groove 71 is the same as that of the first wire groove 41. The second wire groove 71 is designed to allow the sealing baffle 7 to pass over the wire and move to the wire pressing block 4 at the bottom, so that the sealing baffle 7 can effectively seal the connection of a pair of wire pressing blocks 4.
