[0032] Example 1

[0033] Reference Figures 1-4This invention provides an embodiment of a power transmission and transformation engineering monitoring device that is easy to maintain. It adopts a modular design, eliminating the need for complete disassembly and significantly shortening the maintenance cycle. The device includes:

[0034] The modular main unit 100 includes a three-dimensional frame 101. The interior of the three-dimensional frame 101 is provided with multiple partitions 102, which divide the interior of the three-dimensional frame 101 into multiple independent cavities 103. Different functional compartments 104 are provided in the cavities 103 respectively, and the bottom of each functional compartment 104 is slidably connected to the cavity 103 through a sliding component 105.

[0035] The coupling unit 200 is disposed on the three-dimensional frame 101. It includes an elastic contact terminal group 201 disposed on the back of the functional compartment 104 and a female contact group 202 disposed inside the cavity 103 corresponding to the elastic contact terminal group 201. The elastic contact terminal group 201 and the female contact group 202 form elastic contact and conduction when the functional compartment 104 is inserted into the cavity 103.

[0036] Functional compartment 104 includes power supply compartment 106, communication compartment 107, and sensor compartment 108. Power supply compartment 106 has a built-in power supply module that provides power support for the entire monitoring equipment and is the power source for the normal operation of the equipment. Communication compartment 107 integrates a wireless communication module, which is responsible for transmitting the data collected by the sensors to the outside, realizing remote data transmission and monitoring. Sensor compartment 108 is equipped with multiple types of sensors for real-time monitoring of various operating parameters of power transmission and transformation projects, such as voltage, current, and temperature.

[0037] During equipment installation, the three-dimensional frame 101 is first fixed in a suitable position, and the partition 102 is used to divide the space into independent cavities 103. Then, the different functional compartments 104 (power supply compartment 106, communication compartment 107, and sensor compartment 108) are connected to the cavities 103 via sliding components 105. The power supply module in the power supply compartment 106 starts to supply power to the entire equipment, the various types of sensors in the sensor compartment 108 collect the operating parameters of the power transmission and transformation project in real time, and the wireless communication module integrated in the communication compartment 107 transmits these data to an external monitoring center to realize real-time monitoring of the power transmission and transformation project.

[0038] This modular design simplifies and facilitates the installation and initial commissioning of the equipment. Each functional compartment 104 is set up independently, which facilitates subsequent maintenance and expansion. When a functional compartment 104 malfunctions, it can be inspected and repaired specifically without affecting the normal operation of other functional compartments 104.

[0039] Example 2

[0040] Reference Figures 1 to 3This is the second embodiment of the present invention. Unlike the previous embodiment, the sliding component 105 includes a bracket 105a, on which sliders 105b are symmetrically arranged. The inner wall of the cavity 103 is provided with a guide rail 105c that slides with the sliders 105b. The interior of the three-dimensional frame 101 is provided with a positioning structure for fixing the sliders 105b.

[0041] The positioning structure includes a protruding plate 105d fixedly mounted on a three-dimensional frame 101, a push rod 105e slidingly passing through the protruding plate 105d, a slot 105f with a shape matching the end of the push rod 105e being opened at the top of the slider 105b, a vertically arranged through hole 105g being opened on the side wall of the three-dimensional frame 101, a lever 105h being fixedly connected to the push rod 105e and located below the protruding plate 105d, one end of the lever 105h passing through the through hole 105g and extending to the outside of the three-dimensional frame 101, a compression spring 105i being sleeved on the outer periphery of the push rod 105e, the two ends of the compression spring 105i being in contact with the protruding plate 105d and the lever 105h respectively, and the compression spring 105i being used to apply a downward preload to the push rod 105e.

[0042] The bottom of the functional compartment 104 is provided with a mounting side plate 111 with an irregular anti-fool hole 109, and the bracket 105a is provided with an anti-fool boss 110. The anti-fool hole 109 and the anti-fool boss 110 form a unique plug-in matching structure to prevent the functional compartment 104 from being installed incorrectly and to ensure that the functional compartment 104 is correctly installed into the corresponding cavity 103.

[0043] The flexible contact terminal group 201 includes a first PCB board 201a and a flexible probe contact 201b disposed thereon. The female contact group 202 includes a second PCB board 202a and a planar pad contact 202b disposed thereon. The flexible probe contact 201b and the planar pad contact 202b form a three-point contact structure. An elastic connector is provided between the first PCB board 201a and the back of the functional compartment 104.

[0044] The elastic connector includes a guide rod 203, and a guide groove 204 is provided on the first PCB board 201a to slide with the guide rod 203. A spring sheet 205 is fixedly connected between the first PCB board 201a and the back of the functional compartment 104. This design enables reliable elastic contact conduction when the functional compartment 104 is inserted into the cavity 103, ensuring the stability of signal transmission.

[0045] When installing the functional compartment 104, align the irregular anti-foolproof hole 109 on the bottom mounting plate 111 of the functional compartment 104 with the anti-foolproof boss 110 on the bracket 105a to ensure the correct installation orientation of the functional compartment 104. Then, by cooperating with the guide rail 105c on the inner wall of the cavity 103 via the slider 105b on the bracket 105a, the functional compartment 104 is slowly pushed into the cavity 103. When the functional compartment 104 is pushed to the appropriate position, the compression spring 105i pushes the push rod 105e to insert into the slot 105f on the top of the slider 105b, thereby positioning the functional compartment 104. At this time, the elastic contact terminal group 201 on the back of the functional compartment 104 and the female contact group 202 inside the cavity 103 form elastic contact and conduction, completing the electrical connection.

[0046] When disassembling the functional compartment 104, push the lever 105h upwards to make the push rod 105e move upwards against the preload of the compression spring 105i, disengaging from the slot 105f at the top of the slider 105b. Then, slowly pull the functional compartment 104 out of the cavity 103 along the guide rail 105c.

[0047] By optimizing the sliding assembly 105 and the positioning structure, the convenience and accuracy of installing and removing the functional compartment 104 are further improved. The design of the irregularly shaped anti-fool hole 109 and the anti-fool boss 110 avoids installation errors, and the reliable connection of the elastic contact terminal group 201 and the female contact group 202 ensures the stability of signal transmission, thereby improving the reliability and maintenance efficiency of the equipment.

[0048] Example 3

[0049] Reference Figures 1 to 3 This is the third embodiment of the present invention. Unlike the previous embodiment, a storage door 300 is hinged to the three-dimensional frame 101. The storage door 300 is provided with a double-layer sealing structure. The outer layer is a silicone sealing strip 301, and the inner layer is conductive foam 302. Four permanent magnets 303 are evenly distributed on the edge of the storage door 300 frame. The three-dimensional frame 101 is provided with a corresponding magnetic metal adsorption strip 304.

[0050] When the door 300 is opened, the attraction force between the permanent magnet 303 and the magnetically conductive metal adsorption strip 304 is overcome, and the door 300 is pulled outward. At this time, the functional compartment 104 inside the equipment can be installed, disassembled, or repaired. When the door 300 is closed, the door 300 is aligned with the three-dimensional frame 101, and the permanent magnet 303 and the magnetically conductive metal adsorption strip 304 attract each other, making the door 300 tightly closed. The double-layer sealing structure (outer silicone sealing strip 301, inner conductive foam 302) plays a sealing role, preventing dust, moisture, etc. from entering the equipment.

[0051] The design of the door 300 and the double-layer sealing structure improves the equipment's protective performance, effectively preventing dust, moisture and electromagnetic interference from affecting the internal functional compartment 104, extending the equipment's service life and ensuring stable operation in harsh environments.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
