Description

Technical Field

[0001] The utility model relates to the field of engineering safety monitoring, and particularly relates to a drying structure for a hydraulic monitoring cable. Background Art

[0002] At present, a large number of monitoring instrument devices are installed in the high-pressure tunnels and dams of each hydropower station, including monitoring instruments of vibrating wire type, differential resistance type, etc. The supporting or extended high-pressure-resistant hydraulic cables of the monitoring instrument sensors are led out of the hydraulic structure, gathered at the observation station, connected to the manual measurement集线箱 or the automatic acquisition box, and the original observation data of the monitoring instrument is collected through the multi-core wires of the hydraulic cable.

[0003] Usually, the embedded monitoring instrument has a water pressure resistance performance of several MPa, but due to reasons such as the damage of the embedded hydraulic cable, the water ingress of the monitoring instrument defect, and the long-term high-pressure damage of the instrument sealing performance, the internal water in the hydraulic structure seeps into the defect of the hydraulic cable, and then water seeps out at the cable end and enters the集线箱 or the automatic measurement box. There are usually storage batteries, measurement modules, control circuits, heating devices, etc. in the automatic measurement box. Excessive water seepage will cause the environment in the measurement box to be humid and water to accumulate, which will affect the normal operation of the equipment.

[0004] At present, the common method for dealing with the water seepage at the wire end is to remove the cable with the water seepage problem, not connect it to the automatic measurement module of the measurement box, and collect manual data outside the measurement box. Summary of the Invention

[0005] The purpose of the present invention is to provide a drying device for filtering water before the hydraulic monitoring cable enters the measurement box in view of the problem of water seepage of the cable in the measurement box.

[0006] Technical Solution of the Present Invention A drying device for the core wires of a hydraulic monitoring cable. The hydraulic monitoring cable is formed by bundling multiple core wires. First, a middle section of the hydraulic monitoring cable is stripped of the protective outer sheath, and only the middle core wires of the cable are retained to form an exposed core wire stripping section. The core wire stripping section is divided into bundles by a wire divider. The surface of the wire divider has multiple parallel core wire grooves, and each core wire is respectively embedded in a core wire groove and forms a downward bending section.

[0007] A fan is provided on the side of the wire divider.

[0008] The hydraulic monitoring cable is fixed under the top plate of the drying device through a cable fixing bayonet, and a drain port is provided on the bottom plate of the drying device.

[0009] The upper surface of the bottom plate of the drying device is two inclined planes, and a drain port is provided at the junction of the lowest points of the two inclined planes.

[0010] The wire divider is integrally a semi-cylindrical body, and the wire divider is fixed under the top plate of the drying device.

[0011] After passing through the splitter, the core wires are pulled a certain distance by the core wire fixing clips before being bundled together.

[0012] The hydraulic monitoring cable passes through a drying device before entering the measuring box.

[0013] There is a wire holder on each side of the splitter, which holds the wires on both sides of the splitter in place. The beneficial effects of this invention are: The drainage device of this invention can treat the monitoring instrument cable for water seepage before it enters the junction box, ensuring that the cable connected to the junction box is dry and free of water seepage, and maintaining automated observation for monitoring instruments that only leak water but whose sensors can still work normally.

[0016] Example 1: like Figure 1 The drying device is a box-shaped structure. A semi-cylindrical hub 5 is installed on the top plate of the box. The hub 5 has multiple parallel core grooves on its cylindrical surface. The hydraulic monitoring cable 2 is fixed to the underside of the top plate by cable fixing clips 3. A section of the outer shell of the hydraulic monitoring cable 2 is peeled off, exposing the multiple strands of wire 4 in the middle; this section is called the core stripping section. The core stripping section passes through the hub 5, where core wire brackets 7 on both sides of the hub press down on each core. Each core 4 is embedded in a core groove, forming a downward bend in the core under the action of the cylindrical structure. If water seeps after passing through the downward bend, it will drip down the distributor and drain out of the device through the lower drain outlet 9. The upper surface of the device's bottom plate has two slopes, with the lowest point being the intersection of the two slopes, where the drain outlet 9 is located.

[0017] Furthermore, a fan 8 is arranged at the end of the splitter 5 for ventilation and dehumidification inside the device.

[0018] Furthermore, after passing through the splitter 5, the core wire 4 continues to be pulled through the core wire fixing buckle 6. There are three sets of core wire fixing buckles 6 in the figure to ensure that the core wire 4 is dry. Finally, the device is led out into each test box.
