[0006] To achieve the above objectives, this utility model provides the following technical solution: a distributed load monitoring sampling device, comprising a housing A, a housing B hinged to the side edge of housing A, U-shaped grooves formed on the inner walls of both housing A and housing B, a sensing module disposed inside the U-shaped grooves, and positioning components disposed at the top and bottom of both housing A and housing B; the positioning component comprises a semi-circular plate, a threaded hole formed in the middle of the side of the semi-circular plate, a threaded rod threadedly connected inside the threaded hole, a positioning plate disposed at one end of the threaded rod, and several sliding bearings disposed on the surface of the positioning plate; an elastic card disposed on the other side edge of housing A, a slot formed at one end of the elastic card, and a card block adapted to the slot disposed on the other side edge of housing B.

[0007] In one specific embodiment, a device compartment is formed on the surface of the B housing, and a battery module is disposed inside the device compartment. The battery module is electrically connected to the sensing module through wires.

[0008] In one specific embodiment, the semicircular plates at the top and bottom of the A and B housings are distributed opposite to each other, and the inner arc surface of the semicircular plates is in contact with the outer surface of the cable.

[0009] In one specific embodiment, the sliding bearings on the surface of the positioning plate are arranged in a ring array, and the rolling direction of the sliding bearings is perpendicular to the axial direction of the threaded rod.

[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] Figures 1-4 In one embodiment of this utility model, a distributed load monitoring sampling device includes a housing A 1, a housing B 2 hinged to the side edge of housing A 1, a U-shaped groove 3 formed on the inner wall of both housing A 1 and housing B 2, a sensing module 4 disposed inside the U-shaped groove 3, and positioning components 5 disposed at the top and bottom of both housing A 1 and housing B 2.

[0022] The specific problem addressed in this embodiment is: during power system load monitoring sampling, due to the long length of cables in the power system, friction between the cable sheath and the device during monitoring location changes can cause cable damage. This invention achieves non-destructive cable movement and adjustment through the linkage design of the sliding bearing 55 and the threaded rod 53 in the positioning component 5. When the rotating threaded rod 53 pushes the positioning plate 54 to clamp the cable, the rolling direction of the sliding bearing 55 is perpendicular to the axis of the threaded rod 53, reducing friction between the device and the cable during movement. This solves the problem of traditional clamping structures easily scratching cables, improving the convenience and safety of device movement.

[0023] Sensing module 4 uses a low-power digital sensor (such as the DS18B20 temperature sensor, ACS712 current sensor, or HX711 voltage sensor) via SPI / I 2 The C-communication protocol is connected to the built-in signal processing circuit; the battery module 9 uses a lithium polymer battery (such as model 603450, 3.7V / 2000mAh) and outputs 5V DC power through the TPS61090 boost regulator chip, which powers the sensor module 4 through the LTC1472 low-power power management chip. It also integrates the TP4056 charging management circuit to support Type-C interface charging; the wireless transmission unit of the sensor module 4 (such as the ESP32-C3 Wi-Fi / Bluetooth dual-mode chip) is linked with the battery module 9 through dynamic power consumption adjustment, and automatically switches to sleep mode during non-sampling periods to reduce energy consumption, achieving continuous monitoring battery life ≥72 hours.

[0024] The positioning component 5 includes a semi-circular plate 51. A threaded hole 52 is provided in the middle of the side of the semi-circular plate 51. A threaded rod 53 is threadedly connected inside the threaded hole 52. A positioning plate 54 is provided at one end of the threaded rod 53. Several sliding bearings 55 are provided on the surface of the positioning plate 54. In this specific embodiment, an elastic card 6 is provided on the other side edge of the A housing 1. A slot 7 is provided at one end of the elastic card 6. A block that matches the slot 7 is provided on the other side edge of the B housing 2. The A housing 1 and the B housing 2 are hinged to open and close to wrap the cable. The sensing module 4 in the U-shaped groove 3 collects the cable load data. The threaded rod 53 of the rotating positioning component 5 pushes the positioning plate 54 to clamp the cable, and the sliding bearings 55 contact the cable surface. After the housing is closed, the slot 7 of the elastic card 6 and the block of the B housing 2 are elastically engaged and locked. The sliding bearings 55 reduce movement friction, and the elastic card 6 quickly locks the housing, solving the problem of cable damage and improving the protection and movement efficiency of the device.

[0025] In this specific embodiment, a device compartment 8 is provided on the surface of the housing 2 (B), and a battery module 9 is provided inside the device compartment 8. The battery module 9 is electrically connected to the sensing module 4 through wires.

[0026] The equipment compartment 8 is embedded in the shell 2 of the B housing. The battery module 9 is connected to the sensing module 4 of the U-shaped groove 3 through wires to continuously power the temperature, current and other sensors. The integrated battery module 9 realizes wireless external power supply, solves the power supply problem in complex environments and improves the applicability of the device.

[0027] In this specific embodiment, the semicircular plates 51 at the top and bottom of housing A 1 and housing B 2 are distributed opposite to each other, and the inner arc surface of the semicircular plate 51 is in contact with the outer surface of the cable.

[0028] The semicircular plates 51 at the top and bottom of housing A 1 and housing B 2 are distributed opposite each other. The rotating threaded rod 53 makes the inner arc surface of the semicircular plate 51 fit against the outer wall of the cable, forming a ring clamp. The semicircular plate 51 adapts to the curvature of the cable, evenly distributes the clamping pressure, avoids cable deformation, and improves the accuracy of monitoring data.

[0029] In this specific embodiment, the sliding bearings 55 on the surface of the positioning plate 54 are arranged in a ring array, and the rolling direction of the sliding bearings 55 is perpendicular to the axial direction of the threaded rod 53.

[0030] The sliding bearings 55 on the surface of the positioning plate 54 are arranged in a ring array. When the device moves, the sliding bearings 55 roll vertically along the axial direction of the threaded rod 53, reducing the sliding resistance with the cable. The multi-directional rolling bearings 55 reduce frictional damage to the cable surface, enabling the device to move smoothly on the cable and improving the ease of operation.

[0031] In this specific embodiment, the elastic card 6 is made of spring steel, and the depth of the card slot 7 is greater than half the height of the card block;

[0032] The elastic card 6 is made of spring steel. When the housing is closed, the card block is inserted into the card slot 7. The elastic deformation of the spring steel generates a locking force. The depth of the card slot 7 is greater than half the height of the card block to ensure a secure lock. The spring steel elastic card 6 provides a reliable closing force to prevent the housing from opening accidentally and enhances the stability of the device in a vibration environment.

[0033] In this specific embodiment, the inner wall of the U-shaped groove 3 is provided with an insulating layer, the thickness of which is less than one-third of the depth of the U-shaped groove 3;

[0034] An insulating layer is installed on the inner wall of the U-shaped groove 3. The cable and the sensing module 4 are isolated by the insulating layer. The thickness of the insulating layer is less than one-third of the depth of the U-shaped groove 3 to balance insulation and signal sensitivity. The insulating layer blocks the current leakage path of the cable, avoids signal interference, and ensures the accuracy of monitoring data and operational safety.

[0035] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0036] Working principle: The cable is wrapped by closing housing A1 and housing B2 through hinges. Rotating threaded rod 53 pushes positioning plate 54 to clamp the cable. Sliding bearing 55 reduces moving friction. Elastic card 6 and card block fasten and lock the housing. Sensing module 4 in U-shaped groove 3 monitors load data. Battery module 9 in equipment compartment 8 provides power.
