Description

Technical Field

[0001] The utility model relates to the technical field of wire clamps, and particularly to an intelligent temperature measuring wire clamp. Background Art

[0002] Bolt-type special-shaped parallel groove wire clamps are widely used in line branches and substation drainage, and the parallel groove wire clamps and cable joints are the weakest links in the safe operation of distribution network lines. Due to poor construction technology, product quality, poor contact and high temperature, untimely inspection, inconsistent installation direction and other reasons, they lead to overheating, disconnection, short circuit and other faults, causing power outages and wildfires in the power supply system. It is necessary to use wire clamps with built-in early warning functions to improve power supply reliability. However, the existing temperature-sensitive wire clamps still use a parallel groove structure, which is easily affected by on-site construction and tidal direction. Therefore, it is urgent to provide a self-contained temperature-sensitive, remote left-right symmetrical T-structure wire clamp to promptly detect temperature anomalies and alarm functions at the T-junction to avoid failures and improve detection efficiency, power supply reliability and safety.

It will be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It should also be noted that, for ease of description, only the parts related to the relevant utility model are shown in the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0021] Reference Figure 1-Figure 3 The intelligent temperature measuring wire clamp includes a wire clamp body 1, a solar panel 2, a signal transceiver 3, a battery 4, a temperature measuring mechanism (not shown in the figure) and a single-chip microcomputer 5. The solar panel 2 is electrically connected to the battery 4 through a power management chip and a charging circuit, the power management chip is connected to the single-chip microcomputer 5, the signal transceiver 3 is electrically connected to the battery 4 through a communication module and a boost circuit, the communication module is connected to the single-chip microcomputer 5, the battery is connected to the single-chip microcomputer 5 through a voltage stabilizing circuit, and the temperature measuring mechanism is electrically connected to the single-chip microcomputer 5.

[0022] The present invention measures and collects the temperature of the wire clamp in real time through a temperature measuring mechanism, and sends the collected abnormal temperature data to a designated device through a signal transceiver 3, thereby eliminating the need for manual detection of the temperature of the wire clamps one by one, greatly improving the detection efficiency. In addition, the operation of the temperature measuring mechanism is provided by power generation through the solar panel 2, which is safe and environmentally friendly.

[0023] Among them, the solar panel 2 is used to generate electricity and store the generated electricity in the battery 4, providing power for the normal operation of the temperature measuring mechanism, the single-chip microcomputer 5 and the signal transceiver 3. The solar panel 2 can use 5V30mA polycrystalline solar cells, which can effectively convert sunlight into electrical energy. It can still provide good power supply capabilities in a cloudy environment. 8 hours of light a day is enough to provide power for the equipment for about a week, and the TP4056 power management chip is used to effectively manage the charging of the lithium-ion battery. The implementation method of the charging management belongs to conventional technical means and is not the object of protection of this application, so it will not be described in detail here. TP4056 is an excellent single-cell lithium-ion battery constant current / constant voltage linear charger.

[0024] In addition, in order to ensure the working stability of the signal transceiver device 3 , a signal power amplifier may be connected between the communication module and the signal transceiver device 3 .

[0025] Specifically: the solar panel 2 is fixed on the top of the outer shell of the wire clamp body 1; the temperature measuring mechanism is an NTC thermistor.

[0026] Among them, the signal transceiver 3 can use a LoRa module. The LoRa module is equipped with a PA signal amplification module, and the transmission power is increased to 30dBm. The communication distance in open areas reaches more than 11.5 kilometers, and the indoor environment can also reach an effective 3.5 kilometers. The receiving sensitivity reaches -139dBm, ensuring the data communication distance. The LoRa gateway device is inserted in the middle, and a star topology structure is adopted to centrally manage the sub-device nodes to achieve simultaneous communication of 200 nodes. The LoRa gateway uploads data to the cloud platform server through the 4G antenna.

[0027] The solar panel 2 is fixed on the top of the wire clamp body 1, which is more conducive to receiving sunlight and improving power generation efficiency. The temperature measurement mechanism uses an NTC thermistor, which is also called a negative temperature coefficient thermistor. It refers to a thermistor phenomenon and material with a negative temperature coefficient whose resistance decreases exponentially with increasing temperature. Its principle is to use the negative temperature system thermal property of the material. As the temperature increases, the number of carriers increases, so the resistance value decreases.

[0028] NTC thermistors have the following advantages:

[0029] 1. High temperature sensitivity: The resistance value of NTC thermistor changes with the temperature, and its temperature sensitivity is high. Generally speaking, the temperature coefficient of NTC thermistor is negative, that is, as the temperature increases, the resistance value shows a downward trend. This high temperature sensitivity makes NTC thermistor widely used in temperature measurement and control.

[0030] 2. Good stability: NTC thermistors have good stability. The range of its resistance value variation is relatively small, and the variation trend is relatively stable. This enables NTC thermistors to provide accurate and reliable data in temperature measurement and control.

[0031] 3. Fast thermal response: NTC thermistors have a fast thermal response speed. Due to their special structure, they can sense temperature changes in a short time and quickly reflect them in the resistance value. This fast thermal response characteristic enables NTC thermistors to play a timely response role in temperature control and protection circuits.

[0032] 4. Small size: NTC thermistors are relatively small and light. This small feature makes them widely used in various electronic devices. Whether it is mobile phones, computers, home appliances or automotive electronics, NTC thermistors can be seen.

[0033] 5. High reliability: NTC thermistor has high reliability. It has a simple structure and no mechanical moving parts, so it is not easily disturbed by the outside world during use. At the same time, the operating temperature range of NTC thermistor is wide, which can adapt to the working requirements under various environmental conditions.

[0034] Specifically: it also includes an insulating plate 6 fixed to the back of the wire clamp body 1 and a cover 7 arranged on the back of the insulating plate 6, a component cavity is formed between the insulating plate 6 and the cover 7, and the battery 4, the single-chip computer 5, the thermistor and the signal transceiver 3 are arranged in the component cavity; the bottom of the signal transceiver 3 is fixedly arranged in the component cavity, and the top of the signal transceiver 3 partially extends out from the mounting hole 8 on the cover 7.

[0035] In the above technical solution, each component is installed in the component cavity to protect it from wind and rain, thereby increasing its service life. At the same time, the component cavity and the wire clamp body 1 are separated by an insulating plate 6 to ensure the insulation performance of the wire clamp.

[0036] Specifically: a through hole 9 for installing the temperature measuring mechanism is provided on the back of the wire clamp body 1 and the insulating plate 6, wherein the through hole 9 on the back of the wire clamp body 1 is filled with thermal conductive silicone gel.

[0037] In the above technical solution, by providing through holes 9 on the back of the wire clamp body 1 and the insulating plate 6, the temperature measuring mechanism is more closely fitted to the wire clamp body 1, thereby improving the accuracy of temperature measurement.

[0038] The temperature measuring mechanism is connected via the back side of the heat-conducting silicone gel wire clip body 1, which ensures stable and reliable heat conduction while playing a good insulation role, and can prevent the temperature measuring mechanism from being broken down by high voltage.

[0039] Thermally conductive silicone gel is a single-component silicone-based thermally conductive gel. It is soft and does not require curing. It is used in various gaps between electronic components that require low mechanical pressure. It has good thermal conductivity and gap-filling capabilities, and excellent rheological properties, which allows the material to be dispensed under less pressure. Thermally conductive silicone gel has almost no hardness, soft texture, and strong surface affinity. It can be compressed into various very thin shapes and spread on the surface of various non-smooth electronic components, significantly improving the heat transfer efficiency of electronic components. Thermally conductive silicone gel has viscosity and adhesion, is not greasy or dry, has a small reaction force on the device, is easy to compress, is electrically insulating, has low thermal resistance, and has very superior reliability.

[0040] Specifically: the wire clamp body 1 is a "T"-shaped wire clamp. The wire clamp body 1 is provided with an open main line slot 10 and a through hole 9-type branch line slot hole 11, and "Ω"-shaped slide grooves 1313 are provided on both sides of the opening of the main line slot 10. A sealing plate 14 is slidably connected to the "Ω"-shaped slide groove 13, and both sides of the sealing plate 14 have "Ω"-shaped connecting sections 15 that slide in cooperation with the above-mentioned "Ω"-shaped slide groove 13. A wire pressing assembly is connected to the sealing plate 14 and the side wall of the branch line slot hole 11; the wire pressing assembly includes a pressing plate 16, a torque bolt 17 rotatably connected to the pressing plate 16, and a locking nut 1818 threadedly connected to the screw of the torque bolt 17, and the screw portion of the locking nut 18 is threadedly connected to the sealing plate 14 or the side wall of the branch line slot hole 11.

[0041] The wire clamp of the present application adopts a T-shaped structure, which evenly guides currents in different directions, effectively solving the influence of different current directions on the line.

[0042] In addition, the main line duct 10 of the main line part adopts an open design, and the sealing plate 14 on the opening slides with the opening, which can quickly improve the installation efficiency of the construction personnel and can complete the installation within 30 seconds, greatly reducing labor costs and construction pressure.

[0043] The straight part adopts a slot design with one end closed, and an independent pressure plate 16 contact structure can maximize the torque applied to the wire, which can significantly reduce the contact resistance.

[0044] Among them, the anti-loosening nut 18 is made of stainless steel 304 to prevent the wire clamp from being affected by wind swing, vibration and other factors during use, which may reduce the clamping force of the wire clamp, thereby greatly extending the service life of the product.

[0045] Among them, the wire clamp torque bolt 17 is made of high-strength aluminum alloy. After a special heat treatment process, the stability of the torque is guaranteed. The tightening torque is controllable and consistent, ensuring full contact with the cable.

[0046] Specifically: the single chip computer 5 at least includes a timer module, an RTC module and a storage module.

[0047] The timer module is used to trigger the scheduled transmission and transmit the collected temperature data at the specified time, such as sending the scheduled data once or multiple times in a certain time period every day; the RTC module is used to wake up the ultra-low power mode and re-enter the data collection step; the storage module is used to store the collected data.

[0048] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
