参照图1所示，本发明的防漏液***包括散热装置和漏液检测装置，其中散热装置包括转接头1和循环液管2，转接头1的两侧分别设有一段循环液管2，用于实现循环液管2的衔接，构成整个散热***中的一个环节。Referring to Figure 1, the liquid leakage prevention system of the present invention comprises a heat dissipating device and a liquid leakage detecting device, wherein the heat dissipating device comprises a adapter 1 and a circulating liquid pipe 2, and a circulating liquid pipe 2 is respectively arranged on both sides of the adapter 1 It is used to realize the connection of the circulating liquid pipe 2, and constitutes a link in the entire heat dissipation system.
其中循环液管2包括***转接头的金属管21和抵接在转接头1上并与金属管21连通并套设在一起，实现循环液的循环的塑料管22，金属管21和塑料管22之间通过一个卡箍23固定。在工作状态下，循环液经过循环液管2流经转接头再次进入循环液管，其中转接头1与循环 液管2的衔接处则容易滴漏循环液。循环液可以为水，也可以为其他液体，在本实施方式中，为水。The circulating liquid pipe 2 includes a metal pipe 21 inserted into the adapter and a plastic pipe 22 abutting on the adapter 1 and communicating with the metal pipe 21 to realize circulation of the circulating liquid, the metal pipe 21 and the plastic pipe 22 It is fixed by a clamp 23 between them. In the working state, the circulating fluid flows through the circulating liquid pipe 2 through the adapter and enters the circulating liquid pipe again, wherein the junction of the adapter 1 and the circulating liquid pipe 2 is liable to drip the circulating fluid. The circulating liquid may be water or other liquid, and in the present embodiment, it is water.
在本实施方式中漏液检测装置包括包裹转接头1和转接头1与循环液管2连接处的吸水材料3，以及位于金属材料3两侧的电极A和电极B，吸水材料3内侧是探针pin，用于检测电极状态。优选的，在吸水材料3的外层，还包裹一层防水材料，用于避免渗漏。In the present embodiment, the liquid leakage detecting device includes the water absorbing material 3 at the junction of the package adapter 1 and the adapter 1 and the circulating liquid pipe 2, and the electrode A and the electrode B on both sides of the metal material 3, and the inside of the water absorbing material 3 is probed. A pin is used to detect the state of the electrode. Preferably, a waterproof material is also wrapped around the outer layer of the water absorbing material 3 for avoiding leakage.
在本实施方式中，电极A和电极B的形成方式为在吸水材料3的两端内部各绕一层带电的金属环5，进一步的，还设置有用于固定金属环的卡箍4。需要说明的是，上述为本发明的最优方式，实施上，金属环不一定要在吸水材料的两端，也可以为间隔地设置在分别与吸水材料相接处的任意位置，也是可以实施的。In the present embodiment, the electrode A and the electrode B are formed in such a manner that a metal ring 5 is wound around each other at both ends of the water absorbing material 3, and further, a clamp 4 for fixing the metal ring is further provided. It should be noted that the above is the best mode of the present invention. In practice, the metal ring does not have to be at both ends of the water absorbing material, and may be disposed at an arbitrary position at a position where the water absorbing material is respectively spaced apart, and may be implemented. of.
此外，前述的卡箍23和此处的卡箍4均为固定连接作用，其作用与结构完全相同，当然，也可以采用其他的固定方式进行替代，也是可以实施的。In addition, the aforementioned clamp 23 and the clamp 4 herein are all fixedly connected, and their functions and structures are completely the same. Of course, other fixing methods may be used instead, and it may be implemented.
具体在本实施方式中，两金属环各带有5V的电压。吸水材料3在正常状态下不导电，在吸水状态下导电，当产生漏液时，会在漏液处发生导电，连通两电机形成可以被检测的到的电平信号。Specifically, in the present embodiment, the two metal rings each have a voltage of 5V. The water absorbing material 3 is non-conductive under normal conditions and conducts electricity in a water absorbing state. When a liquid leakage occurs, conduction occurs at the liquid leakage, and the two motors are connected to form a level signal that can be detected.
探针pin探测的是低电平；当吸水材料吸水后特质改变可以导电，此时金属环上的电压由于吸水材料导电，导致探针检测到高电平。The probe pin detects a low level; when the water absorbing material absorbs water, the characteristic change can be conductive, and the voltage on the metal ring is electrically conductive, so that the probe detects a high level.
如图2和图3所示，在电极A和电极B两端各放置四根金属探针并用导线引出来，两端的探针摆放位置互相错开，电极的四根金属探针导线连接到控制芯片PA口的四个pin(PA0～PA3)，当水管不漏水时，控制芯片MCU的四个pin(PA0～PA3)检测到的都是低电平。当其中某一部分发生漏液时，则漏液处相应的探针检测到高电平，其余检测到低电平。As shown in Fig. 2 and Fig. 3, four metal probes are placed on both ends of the electrode A and the electrode B, and are led out by the wires. The probe positions at both ends are staggered from each other, and the four metal probe wires of the electrodes are connected to the control. The four pins (PA0~PA3) of the PA port of the chip, when the water pipe does not leak, the four pins (PA0~PA3) of the control chip MCU detect low level. When a leak occurs in one of the sections, the corresponding probe at the leak detects a high level and the rest detects a low level.
当金属块接头与循环液管的连接处有循环液渗出时，循环液立即被吸水材料吸收并向两个方向扩散，当液体扩散到两个金属环端时，由于金属环带了5V的电压，此时该吸水材料也将带电，金属环与内侧放置探针导通，那么四根金属探针引出来导线将被检测到有电平信号，其中电平大小示下拉电阻和吸水材料阻抗等决定，该信号可作为一个反馈信 号。When the circulating fluid leaks out at the joint between the metal block joint and the circulating liquid pipe, the circulating liquid is immediately absorbed by the water absorbing material and diffuses in two directions. When the liquid diffuses to the two metal ring ends, the metal ring carries 5V. Voltage, at this time, the water absorbing material will also be charged, and the metal ring and the inner side of the probe are turned on, then the four metal probes lead out the wire will be detected with a level signal, wherein the level indicates the pull-down resistance and the water absorbing material impedance It is decided that this signal can be used as a feedback signal.
由于循环液在该吸水材料内扩散的方向和快慢都不能确定，假设循环液先渗到了探针a的位置且还没渗到了b，c，d的探针处，那么控制芯片PA0脚检测到一个电平，PA1，PA2，PA3检测到的是低电平，此时控制芯片MCU经过初步计算，此时该吸水材料里面的含水量约为1/4＝25％。Since the direction and speed of the circulating fluid in the water absorbing material cannot be determined, it is assumed that the circulating fluid first penetrates the position of the probe a and has not penetrated the probe of b, c, d, then the control chip PA0 is detected. A level, PA1, PA2, PA3 detects a low level. At this time, the control chip MCU undergoes preliminary calculation, and the water content in the water absorbing material is about 1/4=25%.
依次类推，假设在吸水材料两端各放置n根探针并引出来，然后分别接到控制芯片的(PA0～PAn)pin脚，当水渗到了m根导线的探针处时，那么最终检测出来的吸水材料里面的含水量约为(m/n)*100％。控制芯片MCU将此计算结果发送给显示模块并显示出来。By analogy, it is assumed that n probes are placed at both ends of the water absorbing material and are taken out, and then respectively connected to the (PA0~PAn) pin of the control chip. When the water seeps into the probe of the m wire, the final detection is performed. The water content of the resulting water absorbing material is about (m/n)*100%. The control chip MCU sends the result of the calculation to the display module and displays it.
在工作时，相关工作人员在定期检查过程中可以根据显示模块显示水的含量来判断漏水的严重性，若将70％含水量作为一个预警值，当显示的含水量达到70％时，则工作人员可提前将电源切断，避免危险情况发生。而假如当显示的水含量到达100％时，而工作人员不在现场时，当MCU会立即向电源模块发送一个power off的命令，整个设备的电源模块停止供电。During the work, the relevant staff can judge the seriousness of the water leakage according to the water content displayed by the display module during the regular inspection. If the 70% water content is used as an early warning value, when the displayed water content reaches 70%, it will work. Personnel can cut off the power in advance to avoid dangerous situations. If the displayed water content reaches 100% and the worker is not in the field, the MCU will immediately send a power off command to the power module, and the power module of the entire device stops supplying power.
这样，不仅可以避免漏液的水电接触而产生的安全隐患，同时也监控了循环液的总容量，有效避免了因漏液过多导致循环液不足干烧的风险。In this way, not only the safety hazard caused by the leakage of water and electricity can be avoided, but also the total capacity of the circulating fluid is monitored, thereby effectively avoiding the risk of the circulating fluid being insufficiently dry due to excessive leakage.
实施例二 Embodiment 2
本实施方式，与第一种实施方式大体相同，原理相同，包括散热装置和漏液检测装置，散热装置包括转接头1和循环液管2；漏液检测装置包括包裹转接头1和转接头1与循环液管2连接处的吸水材料3，以及位于金属材料3两侧的电极A和电极B。区别仅在于，在本实施方式中，吸水材料为高吸水性树脂，这种材料吸水性强及渗水均匀。The embodiment is substantially the same as the first embodiment, and has the same principle, including a heat sink and a liquid leakage detecting device. The heat sink includes a joint 1 and a circulating liquid pipe 2; the liquid leakage detecting device includes a package adapter 1 and a joint 1 The water absorbing material 3 at the junction with the circulating liquid pipe 2, and the electrode A and the electrode B on both sides of the metal material 3. The only difference is that in the present embodiment, the water absorbing material is a highly water-absorbent resin, and the material has high water absorption and uniform water permeability.
与实施例一相似，在高吸水性树脂两端各放置n根金属探针。当有漏水现象时，探针位置都同时接触水分而感测到电压，但是针对吸水材料吸水的比重不一样，金属环A,B与金属探针间的阻抗RL也不一样。若吸水材料吸水量与RL有一定的线性关系：Similar to Example 1, n metal probes were placed on both ends of the superabsorbent resin. When there is water leakage, the probe position is exposed to moisture at the same time and the voltage is sensed, but the specific gravity of the water absorption material is different, and the impedance RL between the metal rings A, B and the metal probe is also different. If the water absorption of the water absorbing material has a certain linear relationship with RL:
RL＝x％KMRL=x%KM
其中RL为金属环与金属探针间的阻抗，x％为吸水材料的含水量，KM为吸水材料吸水阻抗系数。Where RL is the impedance between the metal ring and the metal probe, x% is the water content of the water absorbing material, and KM is the water absorption resistance coefficient of the water absorbing material.
从而相应探针检测的电平也随吸水材料的吸水量成线性关系。Therefore, the level detected by the corresponding probe is also linear with the water absorption of the water absorbing material.
控制芯片MCU的每个PA口都将根据吸水量呈现出对应电平，因此可以方便地判断出吸水材料承接水量，分析结果发送给显示模块并显示出来。Each PA port of the control chip MCU will display a corresponding level according to the amount of water absorption, so that it is convenient to judge the amount of water received by the water absorbing material, and the analysis result is sent to the display module and displayed.
检测方案如下：The detection scheme is as follows:
假设当漏水时，某一时刻T时水均匀地渗透到吸水材料的各个部分，设每根探针导线输出的电平值分别为V1,V2,V3……Vn，则当这些电平信号传输给控制芯片MCU时，MCU计算出其平均值Va1＝(V1+V2+V3+…Vn)/n。经过时间T+t(t可以任意设置)后，设每根探针导线输出的电平值分别为V＇1,V＇2,V＇3……V＇n，则当这些电平信号传输给控制芯片MCU时，MCU计算出其平均值Va2＝(V＇1+V＇2+V＇3+…V＇n)/n。It is assumed that when water leaks, water is evenly infiltrated into various parts of the water absorbing material at a certain time T, and the level values of the output of each probe wire are V1, V2, V3, ..., Vn, respectively. When the control chip MCU is given, the MCU calculates its average value Va1 = (V1 + V2 + V3 + ... Vn) / n. After the elapse of time T+t (t can be arbitrarily set), set the level value of each probe wire output to V'1, V'2, V'3...V'n, then when these level signals are transmitted When the control chip MCU is given, the MCU calculates its average value Va2 = (V'1 + V'2 + V'3 + ... V'n) / n.
……….........
依次类推当经过时间T+tn后,MCU计算出其平均值Van。After analogy, after the elapse of time T+tn, the MCU calculates its average value Van.
由于不同时间点情况下，吸水材料的含水量不同，时间越久，吸水材料的含水量越大，因此吸水材料此时的阻抗也越小，其导电性能也越好，那么控制芯片MCU所检测并计算出的探针导线输出电压平均值也越高。将吸水材料含水量(kg)和MCU所检测并计算出的导线输出电压平均值(V)列出一个对于关系：Since the water content of the water absorbing material is different at different time points, the longer the time, the larger the water content of the water absorbing material, so the lower the impedance of the water absorbing material at this time, the better the electrical conductivity, then the control chip MCU detects and The calculated average value of the probe lead output voltage is also higher. The water content (kg) of the water absorbing material and the average value (V) of the wire output voltage detected and calculated by the MCU are listed as a relationship:
M1(kg)……………….Va1(v)M1(kg)...................Va1(v)
M2(kg)……………….Va2(v)M2(kg)...................Va2(v)
M3(kg)……………….Va3(v)M3(kg)...................Va3(v)
Mn(kg)……………….Van(v)Mn(kg)...................Van(v)
其中：Mn>Mn+1>…M3>M2>M1，Van>V an+1>…Va3>Va2>Va1。Wherein: Mn>Mn+1>...M3>M2>M1, Van>V an+1>...Va3>Va2>Va1.
将以上数据统计并记录在相应表格类，然后推算出导线输出电压平均值和吸水材料含水量之间的线性关系，V＝K*M，K为比例常数，将该 关系式写成相应的程序并烧入到MCU中。The above data is statistically recorded and recorded in the corresponding table class, and then the linear relationship between the average value of the wire output voltage and the water content of the water absorbing material is derived, V=K*M, and K is a proportional constant, and the relationship is written into a corresponding program. Burn into the MCU.
假设该吸水材料的含水量饱和值为Mi，其对应导线输出电压平均值Vi，当MCU检测到导线输出电压平均值为Vx时，MCU此时可计算出吸水材料当前的含水量占总含水量饱和值的百分比，即(Vx/Vi)*100％，MCU将此计算结果发送给显示模块并显示出来。则相关工作人员在定期检查过程中可以根据显示模块显示水的含量来判断漏水的严重性，从而做出相应的措施。It is assumed that the water content saturation value of the water absorbing material is Mi, which corresponds to the average value of the output voltage of the wire Vi. When the MCU detects that the average value of the wire output voltage is Vx, the MCU can calculate the current water content of the water absorbing material as a percentage of the total water content. The percentage of the saturation value, ie (Vx/Vi)*100%, the MCU sends the result of the calculation to the display module and displays it. The relevant staff can judge the severity of the water leakage according to the water content of the display module during the regular inspection process, and accordingly take corresponding measures.

If necessary, a Led lamp is built in the relevant area to facilitate the image capturing of the camera, and it is used for real-time monitoring of the discoloration phenomenon of the water absorbing material according to the water absorption.
具体的，本实施方式根据相应吸水材料吸水量不同呈现的颜色建立一个模型，即：整合为一个图形库。并把相应参数加载到图像采集处理芯片内，方便其通过实时监控的图像与图形库里的参数作为比对，进而量化吸水材料的吸水量，进而与饱和状态吸水量比对，生成材料吸水量百分比。Specifically, the present embodiment establishes a model according to the color presented by the water absorption amount of the corresponding water absorbing material, that is, integrates into a graphic library. And the corresponding parameters are loaded into the image acquisition and processing chip, so that it can be compared by the real-time monitoring image and the parameters in the graphic library, thereby quantifying the water absorption amount of the water absorbing material, and then comparing with the water absorption amount in the saturated state to generate the water absorption amount of the material. percentage.
