Description

Technical Field

[0001] This utility model relates to the field of cable monitoring technology, and in particular to a real-time cable status monitoring device. Background Technology

[0002] To ensure the safety of cable operation, temperature sensors are used in related technologies to monitor the cable temperature in real time, thereby reducing the risk of the cable overheating.

[0003] The patent document with publication number CN219736620U discloses a cable temperature monitoring device. This cable temperature monitoring device uses a screw to connect the cable connector to the cable. After the cable and the cable connector are connected, if the cable expands due to heat, there may be excessive pressure between the bolt and the cable, which may damage the cable and / or the temperature sensor. If the cable contracts due to cold, the bolt and the cable will loosen, causing the cable to separate from the temperature sensor, affecting the detection results and resulting in low reliability. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a highly reliable real-time cable condition monitoring device.

[0005] A real-time cable status monitoring device according to some embodiments of the present invention includes: a cable clamp defining a cable penetration area for cable penetration, and the cable clamp having a mounting hole communicating with the cable penetration area; a temperature monitoring component including a temperature detection probe, an elastic element, and a limiting element, at least a portion of the limiting element passing through the mounting hole at one end away from the cable penetration area, the elastic element being disposed within the mounting hole, and one end of the elastic element being connected to the limiting element, the temperature detection probe being movably passing through the mounting hole at one end away from the limiting element, and the end of the elastic element away from the limiting element being connected to the temperature detection probe, wherein at least a portion of the temperature detection probe extends into the cable penetration area.

[0007] In the real-time cable condition monitoring device of this utility model, at least a portion of the limiting member passes through the mounting hole at the end away from the cable penetration area. The limiting member is fixedly connected to the cable clamp and serves to limit and support the elastic member. At least a portion of the temperature detection probe passes through the mounting hole at the end away from the limiting member, and the temperature detection probe can move along the axial direction of the mounting hole. The elastic member is disposed in the mounting hole and connected between the limiting member and the temperature detection probe. The elastic member serves to connect the temperature detection probe and prevent it from sliding out of the mounting hole. On the other hand, when the cable passes through the cable penetration area of ​​the cable clamp, the cable will abut against the temperature detection probe, so that the temperature detection probe is subjected to a force toward the limiting member. At this time, the elastic member will be compressed and apply an elastic force to the temperature detection probe, thereby keeping the temperature detection probe pressed against the cable, thus improving the accuracy of the detection results. In addition, by using elastic elements to keep the temperature detection probe and the cable in close contact, the position of the temperature detection probe can be adaptively adjusted when the size of the cable changes due to thermal expansion and contraction, ensuring that the temperature detection probe and the cable are always in close contact, thereby improving the accuracy of the detection results and ensuring the reliability of the equipment operation.

[0008] According to some embodiments of the present invention, the limiting member is provided with a wire passage, one end of the wire passage faces the temperature detection probe, and the other end penetrates the outer surface of the limiting member;

[0009] The end of the temperature detection probe near the limiting member is connected to a signal line, which passes through the wire passage.

[0010] According to some embodiments of this utility model, the elastic element is a spring, and the signal line also passes through the spring.

[0011] According to some embodiments of this utility model, the limiting member is provided with an external thread, and the wall of the mounting hole at the end away from the cable passage area is provided with an internal thread, and the external thread is connected to the internal thread.

[0012] According to some embodiments of the present invention, a sealing suction cup is sleeved on the outer side of the end of the temperature detection probe away from the limiting member.

[0013] According to some embodiments of the present invention, the sealing suction cup includes a sleeve portion fitted onto the limiting member and a suction cup body connected to the sleeve portion. The outer diameter of the sleeve portion is smaller than the diameter of the mounting hole, and the sleeve portion is configured to extend into the mounting hole as the temperature detection probe moves.

[0014] According to some embodiments of the present invention, the cable clamp includes a first clamping part and a second clamping part connected to the first clamping part, wherein the first clamping part and the second clamping part are movable relative to each other to change the maximum diameter of the cable passage area.

[0015] According to some embodiments of the present invention, one end of the first clamping part is elastically connected to one end of the second clamping part, and the other end of the first clamping part is detachably connected to the other end of the second clamping part.

[0016] According to some embodiments of the present invention, the other end of the first clamping part is provided with a docking groove, and the other end of the second clamping part is provided with a docking strip, the docking strip being inserted into the docking groove.

[0017] According to some embodiments of the present invention, the groove wall of the docking groove is provided with a first docking tooth, and the docking strip is provided with a second docking tooth that meshes with the first docking tooth.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figure 1 , Figure 2 As shown, an embodiment of the present invention provides a real-time cable status monitoring device, which includes a cable clamp 100 and a temperature monitoring component 200, wherein the cable clamp 100 is used to clamp the cable and the temperature monitoring component 200 is used to monitor the temperature of the cable.

[0032] The cable clamp 100 defines a cable penetration area 101 for cable penetration.

[0033] Specifically, the cable clamp 100 is used to clamp the cable. When the cable clamp 100 clamps the cable, the cable passes through the cable passage area 101 defined by the cable clamp 100.

[0034] Furthermore, the cable clamp 100 is provided with a mounting hole 102 that communicates with the cable passage area 101. Specifically, one end of the mounting hole 102 communicates with the cable passage area 101, and the other end penetrates the outer surface of the cable clamp 100.

[0035] Combination Figure 2 and Figure 3 The temperature monitoring component 200 includes a temperature detection probe 210, an elastic element 220, and a limiting element 230. At least a portion of the limiting element 230 passes through the mounting hole 102 at one end away from the cable passage area 101. The elastic element 220 is disposed within the mounting hole 102, and one end of the elastic element 220 is connected to the limiting element 230. The temperature detection probe 210 is movably passed through the mounting hole 102 at one end away from the limiting element 230, and the temperature detection probe 210 is connected to the end of the elastic element 220 away from the limiting element 230. At least a portion of the temperature detection probe 210 extends into the cable passage area 101.

[0036] Specifically, at least a portion of the limiting member 230 passes through the mounting hole 102 at the end away from the cable passage area 101. The limiting member 230 is fixedly connected to the cable clamp 100. The limiting member 230 is used to limit and support the elastic member 220. At least a portion of the temperature detection probe 210 passes through the mounting hole 102 at the end away from the limiting member 230. The temperature detection probe 210 is movable along the axial direction of the mounting hole 102. The elastic member 220 is disposed in the mounting hole 102 and connected to the limiting member 230 and the temperature detection probe. Between 210, the elastic element 220 serves to connect the temperature detection probe 210, preventing the temperature detection probe 210 from sliding out of the mounting hole 102. On the other hand, when the cable passes through the cable passage area 101 of the cable clamp 100, the cable will abut against the temperature detection probe 210, so that the temperature detection probe 210 is subjected to a force toward the limiting element 230. At this time, the elastic element 220 will be compressed and apply an elastic force to the temperature detection probe 210, thereby keeping the temperature detection probe 210 pressed against the cable, thereby improving the accuracy of the detection results.

[0037] It should be noted that in the real-time cable status monitoring device of this utility model, the elastic element 220 is used to make the temperature detection probe 210 press against the cable. The position of the temperature detection probe 210 can be adaptively adjusted when the size of the cable changes due to thermal expansion and contraction, so as to ensure that the temperature detection probe 210 and the cable are always pressed against each other, thereby improving the accuracy of the detection results.

[0038] In addition, when the ambient temperature near the cable decreases and the diameter of the cable decreases, the temperature detection probe 210 will still hold the cable in place under the action of the elastic member 220, thereby preventing the cable from loosening; when the ambient temperature near the cable increases and the diameter of the cable increases, the temperature detection probe 210 will also move toward the limiting member 230, reducing the risk of the temperature detection probe 210 and / or the cable being damaged due to excessive pressure between the temperature detection probe 210 and the cable.

[0039] like Figures 3 to 5 As shown, in some embodiments, the limiting member 230 is provided with a wire passage 231, one end of which faces the temperature detection probe 210 and the other end penetrates the outer surface of the limiting member 230; a signal line 240 is connected to one end of the temperature detection probe 210 near the limiting member 230, and the signal line 240 passes through the wire passage 231.

[0040] Understandably, signal line 240 is used to connect temperature sensing probe 210 to a corresponding computer device, which can display the temperature value of the cable read by temperature sensing probe 210.

[0041] Furthermore, the elastic element 220 is a spring, and the signal line 240 also passes through the spring.

[0042] It should be noted that the two ends of the spring can be welded or glued to the limiting component 230 and the temperature detection probe 210 respectively.

[0043] In some embodiments, the limiting member 230 is provided with an external thread, and the wall of the mounting hole 102 at one end away from the cable passage area 101 is provided with an internal thread, and the external thread is connected to the internal thread.

[0044] It is understandable that the limiting member 230 is threadedly connected to the cable clamp 100. In addition, after the cable is clamped by the cable clamp 100, the pressure between the temperature detection probe 210 and the cable can be adjusted by rotating the limiting member 230 to ensure that the pressure between the temperature detection probe 210 and the cable is within a suitable range.

[0045] Specifically, the limiting member 230 includes a limiting head 232 and a threaded section 233 connected to the limiting head 232. The threaded section 233 has external threads and passes through the mounting hole 102. The size of the limiting head 232 is larger than the size of the mounting hole 102, and the limiting head 232 is located outside the mounting hole 102. The setting of the limiting head 232 can prevent the entire limiting member 230 from passing through the mounting hole 102, which would make it difficult for the limiting member 230 to be operated and rotate.

[0046] Combination Figure 2 and Figure 3In some embodiments, a sealing suction cup 250 is fitted onto the outer side of the end of the temperature detection probe 210 away from the limiting member 230.

[0047] Understandably, when the cable comes into contact with the temperature detection probe 210, the sealing suction cup 250 can hold the cable, thereby sealing the end of the temperature detection probe 210 near the cable. This can serve to prevent water and dust from entering the device, thus preventing the end of the temperature detection probe 210 near the cable from failing due to premature rusting.

[0048] Combination Figure 3 and Figure 5 The sealing suction cup 250 includes a sleeve portion 251 fitted onto the limiting member 230 and a suction cup body 252 connected to the sleeve portion 251. The outer diameter of the sleeve portion 251 is smaller than the diameter of the mounting hole 102, and the sleeve portion 251 is configured to extend into the mounting hole 102 as the temperature sensing probe 210 moves. Thus, the sealing suction cup 250 will not interfere with the movement of the temperature sensing probe 210.

[0049] Of course, in other embodiments, the length of the socket 251 can be short so that even if the cable expands to its maximum size, the socket 251 will not extend into the mounting hole 102.

[0050] Combination Figure 1 and Figure 2 In some embodiments, the cable clamp 100 includes a first clamping portion 110 and a second clamping portion 120 connected to the first clamping portion 110. The first clamping portion 110 and the second clamping portion 120 enclose a cable passage area 101. The first clamping portion 110 and the second clamping portion 120 are movable relative to each other to change the maximum diameter of the cable passage area 101. Thus, the real-time cable status monitoring device of this invention can adapt to cables of different diameters.

[0051] Specifically, one end of the first clamping part 110 is elastically connected to one end of the second clamping part 120, and the other end of the first clamping part 110 is detachably connected to the other end of the second clamping part 120.

[0052] It should be noted that the entire cable clamp 100 is made of plastic components and is elastic. Although one end of the first clamping part 110 and one end of the second clamping part 120 are integrally connected, by applying force to the first clamping part 110 and the second clamping part 120, the first clamping part 110 and the second clamping part 120 can rotate relative to each other.

[0053] Furthermore, the other end of the first clamping part 110 is provided with a docking groove 121, and the other end of the second clamping part 120 is provided with a docking strip 111, which is inserted into the docking groove 121.

[0054] Furthermore, the groove wall of the mating groove 121 is provided with first mating teeth, and the mating bar 111 is provided with second mating teeth that mesh with the first mating teeth. The length of the mating bar 111 extending into the mating groove 121 can be adjusted, thereby allowing the cable clamp 100 to be adjusted based on the diameter of the cable, thus ensuring that the cable clamp 100 clamps the cable tightly.

[0055] It should be noted that before the cable clamp 100 of this utility model clamps the cable, the mating bar 111 does not extend into the mating groove 121, and the other end of the first clamping part 110 and the other end of the second clamping part 120 can be separated, so that the cable clamp 100 can be easily sleeved on the outside of the cable.

[0056] Understandably, by moving the wall of the mating groove 121, the mating groove 121 can be enlarged, thereby allowing the mating strip 111 to be pulled out from the mating groove 121.

[0057] In the real-time cable condition monitoring device of this utility model, at least a portion of the limiting member 230 passes through the mounting hole 102 at one end away from the cable penetration area 101. The limiting member 230 is fixedly connected to the cable clamp 100. The limiting member 230 is used to limit and support the elastic member 220. At least a portion of the temperature detection probe 210 passes through the mounting hole 102 at one end away from the limiting member 230. The temperature detection probe 210 can move along the axial direction of the mounting hole 102. The elastic member 220 is disposed in the mounting hole 102 and connected to the limiting member 230. Between the temperature detection probe 210 and the cable clamp 100, the elastic element 220 serves to connect the temperature detection probe 210, preventing it from slipping out of the mounting hole 102. On the other hand, when the cable passes through the cable penetration area 101 of the cable clamp 100, the cable abuts against the temperature detection probe 210, subjecting it to a force towards the limiting element 230. At this time, the elastic element 220 is compressed, applying an elastic force to the temperature detection probe 210, thus keeping it pressed against the cable and improving the accuracy of the detection results. Furthermore, by using the elastic element 220 to press the temperature detection probe 210 against the cable, the position of the temperature detection probe 210 can be adaptively adjusted when the cable size changes due to thermal expansion and contraction, ensuring that the temperature detection probe 210 and the cable remain pressed at all times, thereby improving the accuracy of the detection results and ensuring the reliability of equipment operation.
