Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cable insulation layer detection, in particular to an integrated thermal stress and deformation detection machine for cable insulation layers. Background Art
[0002] The cable insulation layer is a key material wrapped around the outside of the cable conductor (such as copper wire or aluminum wire). Its core function is to prevent current from flowing along unintended paths (that is, to prevent conduction between conductors or between the conductor and the ground), while protecting the conductor from environmental factors (such as moisture, chemicals, heat, and mechanical damage). The thermal stress test of the insulation layer is mainly thermal deformation testing, which is to place the insulation sample at a specified temperature and pressurize it to measure the thickness deformation rate of the insulation layer after being compressed. In addition, thermal deformation testing will also contact the sample through a probe to monitor dimensional changes under programmed heating conditions.
[0003] At present, the thermal stress deformation detection of cable insulation layer mainly changes the temperature and pressure conditions, and then uses laser scanning or probes to measure the deformation. Generally, the temperature rise of the cable during use is caused by the heat of the internal conductor. The heating position of the cable insulation layer is on the inside. In general thermal stress deformation detection, the heating position of the cable insulation layer is on the outside, which makes the heating position of the insulation layer different, resulting in different deformation effects.
[0004] In addition, since cables are mostly laid by lifting or laying in underground passages in real use environments, when lifted, the cables will be in a partially bent state. When laid underground, due to the influence of the cable connection points and the channel position, the cables will be partially bent and stretched. When testing the thermal stress deformation of the cable insulation layer, most of the time a section of cable is selected to be laid straight for testing, which is different from actual use. As a result, the measured thermal deformation values are somewhat different from the thermal deformation values in the real environment. Therefore, a detection device is needed to solve the problem. Summary of the Invention
[0005] The present invention provides an integrated thermal stress deformation detection machine for cable insulation layers, which utilizes a mechanism that simulates arc bending, folding, and lifting and bending to help perform thermal stress deformation detection on cables in a simulated real laying state. In addition, the two ends of the cable can be connected to realize power-on, allowing heat to be generated inside the cable, thereby increasing the temperature inside and outside the cable insulation layer, thereby solving the problems raised in the above-mentioned background technology.
[0006] In order to achieve the above-mentioned object, the present invention provides an integrated detection machine for thermal stress and deformation of cable insulation layer, comprising a lower box body and a detachable upper box body, the top of the upper box body is provided with a heating mechanism for heating, the bottom of the lower box body is provided with a pressurizing device for pressurizing, power-on devices are provided on both sides of the lower box body, partitions and sealing rubber sleeves are provided between the power-on devices and the lower box body, and the shapes of the partitions and sealing rubber sleeves are adapted to the edges of the upper box body to ensure the sealing of the edges when the upper box body and the lower box body are combined to form a sealed cylindrical detection box body, and also comprising a laying channel provided on the inside of the lower box body, the laying channel comprising an upper channel and a lower channel, the upper channel being concave for laying cables and having locking hoops at both ends, and the lower channel being in contact with the bottom wall of the lower box body; The upper channel is provided with a through slot and cable locking heads for connecting to powered equipment are provided at both ends; The shape adjustment mechanism includes an arc-shaped lifting block, a corner lifting block and a lifting simulation support block located below the through-groove. The top surface of the arc-shaped lifting block is a convex arc, which is used to make the cable in a bent state. The top of the corner lifting block is a sharp corner, which is used to make the cable in a bent state. The lifting simulation support block is a concave block, which is used to lift both ends of the cable and make the middle part droop to simulate a lifting state. The upper channel is provided with three through-grooves, which correspond to the lifting paths of the arc-shaped lifting block, the corner lifting block and the lifting simulation support block respectively. The driving assembly is an electric push rod vertically arranged on the lower channel, thereby driving the arc-shaped lifting block, the corner lifting block and the lifting simulation support block to pass through the through-grooves and invade the laying path of the upper channel respectively to adjust the cable shape; The detection probe system includes a side detection probe and an adjustable detection probe. The side detection probe is arranged on the side wall of the lower box body, facing the top of the laying channel to detect the flat cable. The adjustable detection probe is arranged below the shape adjustment mechanism to detect the cable after shape adjustment.
[0007] As a further improvement of the present technical solution, the arc-shaped jacking block, the corner jacking block and the lifting simulation support block are all provided with long grooves, and the adjustable detection probe includes a deformation detection probe and a jacking member for driving the deformation detection probe to rise and fall; The deformation detection probe passes through the long slot and contacts the cable to independently detect the deformation of the insulation layer under bending, folding and sagging.
[0008] The adjustable detection probe further includes a horizontal control member that drives the lifting member to move horizontally; The horizontal control member includes a horizontal adjustment control and a sliding block. The sliding block is installed to slide along the length direction of the lower channel. The horizontal adjustment control is set on the lower channel, and the output end is connected to the sliding block and drives the sliding block to slide. The lifting member is set on the sliding block, and the sliding block can be controlled to slide by the horizontal adjustment control, thereby adjusting the horizontal position of the lifting member and the deformation detection probe.
[0009] As a further improvement of the present technical solution, a plurality of side detection probes are provided on the side wall of the lower box body, and the side detection probes include a driving member and a probe body. The driving member passes through the side wall of the lower box body, and the probe body is provided on the output end of the driving member so as to drive the probe body to approach the paving path of the upper channel through the driving member. Among them, multiple side detection probes are spaced between the arc-shaped jacking block, the corner jacking block and the lifting simulation support block, and are used to detect the flat section of the cable that is not affected by the shape adjustment mechanism.

[0011] In this technical solution, the cable locking head uses an energized connector and an adjustable telescopic frame to pass current through both ends of the locked cable, causing the cable to self-heat internally. Combined with the sealed box, heating mechanism and pressurizing equipment, a dual real environment of internal heating and external heating and pressurization is formed, synchronously simulating the cable power-on condition and the environmental temperature and pressure load, improving the authenticity of the test data.
[0012] Compared with the prior art, the present invention provides an integrated thermal stress and deformation detection machine for cable insulation layers, which has the following beneficial effects: 1. This invention uses arc-shaped lifting blocks, corner lifting blocks, and lifting simulation support blocks, driven by electric push rods, to actively lift the cables on the upper channel. This allows the cables to form four realistic working conditions: flat, upwardly bent, upwardly bent, and lifted and bent downward. This integrates multi-form cable deformation simulation within a single device. 2. An adjustable detection probe is integrated under the shape adjustment mechanism. The horizontal control member drives the sliding block to move horizontally to accurately locate the detection point. The lifting member pushes the deformation detection probe vertically through the long slots of each lifting block, directly contacting the insulation layer of the curved and bent sections, achieving full coverage detection of flat and curved areas. 3. Through the active shape adjustment mechanism and dynamically adjustable detection probe system, the integrated detection of thermal stress and deformation of the cable insulation layer under multi-morphological real working conditions is realized in a heated and pressurized sealed space, providing high-confidence data support for cable reliability design, thus avoiding the problems of traditional methods such as single environment, shape limitations and large detection blind spots.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0016] Reference Figures 1 to 8 As shown, the present invention provides an integrated detection machine for thermal stress and deformation of cable insulation layer. In order to simulate the real environment and detect the thermal stress and deformation data of the cable under various conditions when detecting the thermal stress and deformation of the cable insulation layer, so as to make the thermal stress and deformation detection of the insulation layer more realistic, the device is provided with a lower box 1 and a detachable upper box 2, as shown in FIG. Figure 2As shown, the lower box body 1 and the upper box body 2 form a cylindrical detection box body, and a sealed rubber pad is provided at the edge of the lower box body 1 and the upper box body 2, and the lower box body 1 and the upper box body 2 are sealed and locked by a threaded locking structure at the edge, so that a sealed space is formed inside the two after they are merged. A heating mechanism 3 for heating is provided at the top of the upper box body 2, wherein the heating mechanism 3 can be a hot air drying mechanism, and the temperature can be ensured to reach 120±2℃. The sealed space can be heated by the heating mechanism 3, and a pressurizing device for pressurizing is provided at the bottom of the lower box body 1. Preparation 4, wherein the pressurizing device 4 can be specifically a booster pump, which can pressurize the sealed space, thereby completing the temperature and pressure control in the sealed space formed by the lower box body 1 and the upper box body 2, and facilitating the detection of thermal stress deformation of the insulation layer. Power-on devices 5 are provided on both sides of the lower box body 1, wherein the power-on devices 5 can be specifically power supplies, which energize the cable to obtain thermal stress detection data of the cable under energized conditions and normal conditions. During normal detection, a control group can be set to obtain thermal stress detection data when the cable is not energized, thereby reducing data errors; The integrated detection machine for thermal stress and deformation of cable insulation layer also includes a laying channel 6 and a shape adjustment mechanism arranged on the inner side of the lower box body 1. The laying channel 6 includes an upper channel 62 and a lower channel 63. The upper channel 62 is a long channel for laying cables, and the lower channel 63 fits the arc-shaped bottom wall of the lower box body 1. Locking hoops for locking cables are provided on both sides of the upper channel 62, which are used to lock the two ends of the cable laid on the upper channel 62. Cable locking heads 61 for connecting to the power-on device 5 are provided at both ends of the upper channel 62. When the cable is laid on the upper channel 62, the cable can be connected through the cable locking heads 61 on both sides, so that during the detection process, the cable is energized and the cable can be heated from the inside, thereby simulating the thermal deformation of the insulation layer of the cable when it is energized in actual use and obtaining relevant data. The upper channel 62 is provided with a through groove; like Figure 6 and Figure 7 As shown, the shape adjustment mechanism includes an arc-shaped lifting block 7, a corner lifting block 8, and a lifting simulation support block 9. The arc-shaped lifting block 7, the corner lifting block 8, and the lifting simulation support block 9 are all driven to rise and fall by a driving assembly 10. The arc-shaped lifting block 7, the corner lifting block 8, and the lifting simulation support block 9 can invade into the upper channel 62 to lift the cables laid on the upper channel 62 and complete the shape adjustment. The upper channel 62 and the lower channel 63 are both long arc-shaped channels, and the concave portion of the upper channel 62 is adapted for the placement of cables. Three through-grooves are provided at the bottom of the upper channel 62, corresponding to the positions of the arc-shaped jacking block 7, the corner jacking block 8, and the lifting simulation support block 9. Among them, the driving component 10 is an electric push rod, and is vertically arranged on the lower channel 63. The arc-shaped jacking block 7, the corner jacking block 8 and the lifting simulation support block 9 are respectively arranged on the output end of a driving component 10 to realize the lifting and lowering drive of the arc-shaped jacking block 7, the corner jacking block 8 and the lifting simulation support block 9, so that the arc-shaped jacking block 7, the corner jacking block 8 and the lifting simulation support block 9 are controlled to rise respectively, pass through the through groove and invade into the paving path of the upper channel 62.
[0017] It also includes side detection probes 11 and adjustable detection probes 12. The side detection probes 11 are arranged on both sides of the lower box body 1, and the side detection probes 11 are directly above the laying channel 6. The side detection probes 11 can be used to perform deformation detection on the outer insulation layer of the cable laid flat on the upper channel 62.
[0018] like Figure 6 and Figure 8 The arc-shaped lifting block 7 is a convex arc-shaped block on the top surface, the top of the corner lifting block 8 is a sharp corner, the lifting simulation support block 9 is a concave block, and the arc-shaped lifting block 7, the corner lifting block 8 and the lifting simulation support block 9 are all provided with long grooves, and the adjustable detection probe 12 is arranged under the arc-shaped lifting block 7, the corner lifting block 8 and the lifting simulation support block 9, and the detection end of the adjustable detection probe 12 passes through the corresponding long groove, so that after the arc-shaped lifting block 7, the corner lifting block 8 and the lifting simulation support block 9 complete the shape adjustment of the cable on the upper channel 62, the adjustable detection probe 12 is used to complete the thermal stress deformation detection of the cable insulation layer; like Figure 7 As shown, the adjustable detection probe 12 is arranged below the arc jacking block 7, the corner jacking block 8 and the lifting simulation support block 9. The adjustable detection probe 12 includes a deformation detection probe 1201, a jacking member 1202 and a horizontal control member 13. The horizontal control member 13 includes a horizontal adjustment control 1301 and a sliding block 1302. The sliding block 1302 is slidably installed on the lower channel 63, and the sliding direction is the same as the length direction of the laying channel 6. The horizontal adjustment control 1301 is arranged on the lower channel 63, and the output end of the horizontal adjustment control 1301 is connected to the sliding block 1302, so that the horizontal adjustment control 1301 can control the sliding block 1302 to slide horizontally. The jacking member 1202 is arranged on the sliding block 1302 in the vertical direction. The deformation detection probe 1201 is arranged at the jacking end of the jacking member 1202, and the end of the deformation detection probe 1201 passes through the long slot and faces the cable on the upper channel 62. The horizontal adjustment control 1301 can control the horizontal sliding of the sliding block 1302, thereby adjusting the position of the deformation detection probe 1201 under the arc-shaped lifting block 7, the corner lifting block 8 and the lifting simulation support block 9. After the arc-shaped lifting block 7, the corner lifting block 8 and the lifting simulation support block 9 complete the shape adjustment of the cable, the deformation detection probe 1201 is used for detection.
[0019] It should be clarified that when the arc-shaped lifting block 7, the corner lifting block 8 and the lifting simulation support block 9 pass through the through groove and invade the laying path of the upper channel 62, the cable laid flat on the upper channel 62 will be supported. At this time, the cable will be in a bent state on the arc-shaped lifting block 7, and in a bent state lifted by the conical corner on the corner lifting block 8. At the lifting simulation support block 9, both ends of the cable will be lifted by the concave lifting simulation support block 9. At this time, the part of the cable located in the middle of the lifting simulation support block 9 will bend down under the action of gravity, simulating the bending state of the cable under gravity when being lifted. At this time, the deformation detection probe 1201 can be used to perform thermal stress deformation detection on the cable insulation layer in these states to help obtain real data.
[0020] like Figure 6 and Figure 7 As shown, the side detection probe 11 includes a driving member 111 arranged through the side wall of the lower box body 1 and a probe body 112 arranged at the end of the driving member 111, and the probe body 112 is facing the cable laying position of the upper channel 62, so that the lateral thermal stress deformation detection of the laid cable can be performed. A plurality of side detection probes 11 are arranged on the side wall of the lower box body 1, and are spaced apart from the arc-shaped lifting block 7, the corner lifting block 8 and the lifting simulation support block 9, so that the side detection probe 11 can detect the part of the cable whose shape is not affected by the arc-shaped lifting block 7, the corner lifting block 8 and the lifting simulation support block 9.
[0021] It should be made clear that if Figure 8 As shown, when the arc-shaped lifting block 7, the corner lifting block 8 and the lifting simulation support block 9 respectively lift part of the cable, the cable will form four states, namely, the flat state, the upward bending state, the upward bending state and the lifting and bending state. The two sides of the cable and the lifting part remain in a flat state, and the side detection probe 11 corresponds to detecting the cable in the flat state.
[0022] like Figure 5 As shown, the cable locking head 61 includes an electric connector 611 and an adjustable telescopic bracket 612. The adjustable telescopic bracket 612 is arranged on one side of the upper channel 62. The electric connector 611 is arranged at the telescopic end of the adjustable telescopic bracket 612, and the electric connector 611 is directly opposite to the side of the upper channel 62. The electric connector 611 is connected to the power supply device 5 through a line, so that when the cable is placed on the upper channel 62, it can be controlled by the adjustable telescopic bracket 612 on both sides of the upper channel 62 to control the electric connectors 611 on both sides to approach and connect to the two sides of the cable, so that current passes through the cable, causing the cable to self-heat, so that the outer insulation layer of the cable can form a dual heating state inside and outside.
[0023] like Figure 5As shown, the power connector 611 is a circular connector and fits the arc surface of the upper channel 62. When the cable is laid flat on the upper channel 62, the power connector 611 will fit the arc surface when it is close to the end of the cable, so that the power connectors 611 at both ends form a similar opposite clamping effect on the cable. At the same time, the power connector 611 will fit tightly to the wire at the end of the cable, so that the cable, the power connector 611 and the power device 5 form an electrical path, thereby achieving power-on heating of the cable.
[0024] Working principle: Separate the upper box body 2 and lay the cable to be tested in the upper channel 62. At this time, the driving component 10 can be started. The driving component 10 drives the arc-shaped lifting block 7, the corner lifting block 8 and the lifting simulation support block 9 to move upward through the through slot, lifting the cable, so that the cable forms bending, bending and downward bending shapes on the upper channel 62, simulating various forms of current in actual use. Then the two ends of the cable are locked by the locking clamp. At this time, by adjusting the adjustable telescopic frame 612, the power connector 611 is connected to both sides of the cable respectively. At this time, the power-on device 5 is started to allow the current to flow through the power connector 611 through the cable to form a power-on use state. The upper box body 2 is closed to form a sealed space between the lower box body 1 and the upper box body 2. At this time, the heating mechanism 3 and the pressurizing device 4 are started to heat and pressurize the sealed space, so that the cable insulation layer is subjected to thermal stress deformation when the cable is energized. At this time, the thermal stress of the cable in the flat state can be completed by the side detection probe 11. Deformation detection. In addition, the horizontal adjustment control 1301 can be started to control the sliding block 1302 to slide horizontally, thereby adjusting the position of the deformation detection probe 1201 under the arc lifting block 7, the corner lifting block 8 and the lifting simulation support block 9 respectively, and starting the lifting part 1202 to allow the deformation detection probe 1201 to move upward through the long slot and contact the bent, folded and bent cables respectively, thereby detecting the thermal stress deformation data of the cable in the upward bending state, the upward bending state and the lifting and bending state. In addition, two groups of control groups can be set during the detection. One group is the cable in the energized state but the heating mechanism 3 is not working, and the heat data generated internally when the cable itself is working is obtained. The other group is in the power-off state, and the heating mechanism 3 works to obtain the thermal stress deformation data of the cable itself under normal conditions, further enhancing the accuracy of the data, and combining multiple groups of detection data to comprehensively evaluate the thermal stress deformation of the cable insulation layer, while facilitating the acquisition of thermal stress deformation data of the cable under different forms.
