[0001] The invention relates to a detection device, in particular to a high-voltage cable snow thickness detection device applied in the field of snow detection. Background Art

[0002] High-voltage cable is a type of power cable, mainly used to transmit electricity between 1kv-1000kv, and is mostly used in the main roads of power transmission and distribution.

[0003] High-voltage cables are usually installed in the air. During heavy snow, snow will accumulate on the high-voltage cables. When there is too much snow, that is, when the snow reaches a certain thickness, the weight and load of the high-voltage cables will be greatly increased, which may cause the cables to bend and sag, increasing the risk of cable breakage. At this time, the snow on the high-voltage cables needs to be cleared as soon as possible.

[0004] Cleaning snow on high-voltage cables is a difficult and dangerous task. In order to avoid unnecessary cleaning, it is necessary to detect the thickness of snow on the high-voltage cables, and then determine whether it is necessary to clean the snow on the high-voltage cables based on the detection results. Therefore, we propose a high-voltage cable snow thickness detection device. Summary of the invention

[0007] In the above-mentioned high-voltage cable snow thickness detection device, the staff can remotely control the simulated cable snow detection mechanism through the cable detection temperature sensor, so that the simulated cable snow detection mechanism can indirectly detect and calculate the thickness of snow on the high-voltage cable by detecting the snow on the simulated cable sleeve. The staff can determine whether it is necessary to clear the snow based on the detection results, which can prevent the cable from being damaged due to excessive snow accumulation and effectively avoid unnecessary cleaning.

[0010] As a further improvement of the present application, the heat transfer sleeve is slidingly and sealingly connected to the heat transfer rod, and the top end of the heat transfer rod is lower than the bottom end of the heat transfer core rod, so that the heat transfer rod and the heat transfer sleeve will not effectively support the simulated cable sleeve, thereby preventing the detection of snow thickness and weight from being affected. A cavity is opened inside the heat transfer core rod to reduce the weight of the heat transfer core rod and improve the accuracy of the detection.

[0011] As a further improvement of the present application, the outer surfaces of the heat transfer rod and the heat transfer sleeve are coated with heat insulating paint, and the support box and the partition are made of heat insulating material to reduce heat loss.

The simulated cable snow inspection mechanism can also monitor the weight of the snow on the high-voltage cable. When the weight of the snow reaches the warning value, the simulated cable snow inspection mechanism will also send an alarm to the interconnection terminal, prompting the relevant staff to take corresponding measures in time. , and because the detection is indirect detection, not direct detection of the high-voltage cable, on the one hand, it can prevent the cable from being damaged due to the detection, and on the other hand, the simulated cable snow detection mechanism can be at a certain distance from the high-voltage cable, thereby improving the safety of the detection device.

[0028] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0029] The first implementation method:

[0030] Figure 1-6A device for detecting snow thickness on a high-voltage cable is shown, comprising a quasi-cable snow inspection mechanism, an interconnection terminal, and a cable inspection temperature sensor for detecting the temperature of the high-voltage cable and having a wireless communication function. The quasi-cable snow inspection mechanism comprises a mounting plate 101 and a quasi-inspection component and a snow inspection intelligent controller 003 mounted on the mounting plate 101. The quasi-inspection component comprises a support box 201 fixedly mounted on the mounting plate 101, a partition 202 matching the support box 201 is fixedly mounted inside the support box 201, a pressure sensor 203 is fixedly mounted on the top of the partition 202, a quasi-cable sleeve 204 matching the high-voltage cable is arranged above the support box 201, a pressure transmission rod 205 is fixedly connected to the bottom end of the quasi-cable sleeve 204, the pressure transmission rod 205 penetrates the top outer wall of the support box 201 and extends to abut against the pressure sensor 203, and the pressure transmission rod 205 is slidably and sealingly connected to the top outer wall of the support box 201 Heat transfer plates 206 are embedded and penetrated on the outer walls of both sides of the support box 201, and semiconductor refrigerators 207 are fixedly installed on the two heat transfer plates 206. A cross plate 208 is fixedly installed on the pressure transfer rod 205, and a pseudo temperature sensor 209 for detecting the temperature of the pseudo cable sleeve 204 is fixedly installed on the top of the cross plate 208. L-shaped heat transfer rods 210 are penetrated on the outer walls of both sides of the support box 201, and a heat transfer sleeve 211 matching therewith is sleeved on one end of the heat transfer rod 210 away from the support box 201. A heat transfer core rod 212 matching therewith is sealed and fixedly connected to the inner side of the pseudo cable sleeve 204, and the top of the heat transfer sleeve 211 penetrates the outer wall of the bottom end of the pseudo cable sleeve 204 and extends to be fixedly connected to the heat transfer core rod 212. The snow detection intelligent controller 003 is provided with a temperature adjustment module, an analysis and calculation module, and a snow detection master control module with wireless communication function.

[0031] See also Figure 1-6 The material and diameter of the simulated cable sheath 204 are the same as those of the outermost sheath of the high-voltage cable. The interconnection terminal is a computer or mobile phone with wireless communication function. The heat transfer plate 206, the heat transfer rod 210, the heat transfer sleeve 211, and the heat transfer core rod 212 are all made of heat conductive materials. The cold end of one semiconductor refrigerator 207 is in contact with the corresponding heat transfer plate 206, and the hot end of the other semiconductor refrigerator 207 is in contact with the corresponding heat transfer plate 206. The interconnection terminal is connected to the snow detection master control module by wireless signals. The snow detection master control module is electrically connected to the pressure sensor 203 and the simulated temperature sensor 209. The pressure sensor 203 is electrically connected to the analysis and calculation module, the analysis and calculation module is electrically connected to the snow detection master control module, the snow detection master control module is connected to the cable detection temperature sensor by wireless signals, the simulated temperature sensor 209 is electrically connected to the isothermal adjustment module, the cable detection temperature sensor is connected to the isothermal adjustment module by wireless signals, and the isothermal adjustment module is electrically connected to both semiconductor refrigerators 207.

[0032] See also Figure 1-6, the relevant staff can install the simulated cable snow detection mechanism to a suitable position through the mounting plate 101 according to the actual situation, so that the simulated cable sleeve 204 and the high-voltage cable are at the same height and in the same weather environment. When it snows, the staff can issue an instruction to detect the thickness of snow to the snow detection master control module through the interconnection terminal. After receiving the instruction, the snow detection master control module will start the pressure sensor 203. When snow falls on the high-voltage cable, it will also fall on the simulated cable sleeve 204, that is, snow will accumulate on the simulated cable sleeve 204 and the high-voltage cable at the same time, so detecting the snow on the simulated cable sleeve 204 is equivalent to detecting the snow on the high-voltage cable. With the generation of snow, the pressure data detected by the pressure sensor 203 will gradually increase, and the pressure detected by the pressure sensor 203 will increase. The force data will be transmitted to the analysis and calculation module, which can calculate the weight of the snow on the simulated cable sleeve 204 by analyzing the changes in the pressure data, and then calculate the average thickness of the snow in combination with the snow density, the length of the simulated cable sleeve 204 and other data. The analysis and calculation module will perform analysis and calculation at regular intervals until the staff issues an instruction to stop detection to the snow inspection master control module through the interconnected terminal. Each time the analysis and calculation module calculates the result, it will immediately feed it back to the snow inspection master control module, which will then send it to the interconnected terminal for the staff to view. In addition, the staff can also reasonably set a weight warning threshold according to the actual situation and the relevant performance of the high-voltage cable. After the analysis and calculation module calculates the weight of the snow on the simulated cable sleeve 204, it can also The weight of the snow on the high-voltage cable can be calculated based on the length ratio between the simulated cable sleeve 204 and the high-voltage cable. Conversely, the analysis and calculation module can infer the corresponding pressure warning threshold based on the weight warning threshold. When the pressure data detected by the pressure sensor 203 reaches the pressure warning threshold, the analysis and calculation module will feedback to the snow detection master control module, and then the snow detection master control module will send an alarm to the interconnected terminal so that the staff can take corresponding measures in time. In addition, each time the analysis and calculation module calculates the thickness of the snow, it will also calculate the weight of the snow, and the calculation result will be sent to the interconnected terminal together with the calculation result of the snow thickness. When the staff determines whether the snow on the high-voltage cable needs to be cleared, they can combine the two sets of data to make a judgment, thereby improving the accuracy of the judgment. When the master control module starts the pressure sensor 203, it will also start the pseudo temperature sensor 209 and the cable temperature sensor. The cable temperature sensor is installed at the high-voltage cable and can detect the temperature of the high-voltage cable. The pseudo temperature sensor 209 can detect the temperature of the pseudo cable sheath 204. The temperature data detected by the pseudo temperature sensor 209 and the cable temperature sensor will be fed back to the temperature control module. Since the high-voltage cable will generate a certain amount of heat when transmitting electricity, the temperature of the high-voltage cable will usually be higher than the pseudo cable sheath 204. When the temperature of the high-voltage cable is higher than the pseudo cable sheath 204, the temperature control module starts the semiconductor refrigerator 207 with the hot end attached to the corresponding heat transfer plate 206. Under the heat conduction effect of the heat transfer rod 210, the heat transfer sleeve 211 and the heat transfer core rod 212,The temperature of the simulated cable sheath 204 can be increased. When the temperature of the high-voltage cable is lower than that of the simulated cable sheath 204, the isothermal adjustment module starts the semiconductor refrigerator 207 whose cold end is in contact with the corresponding heat transfer plate 206, which can reduce the temperature of the simulated cable sheath 204. The isothermal adjustment module will adjust the temperature of the simulated cable sheath 204 according to the temperature data detected by the simulated temperature sensor 209 and the cable temperature sensor, so as to keep the temperature of the simulated cable sheath 204 consistent with that of the high-voltage cable as much as possible, so as to make the snow accumulation conditions on the simulated cable sheath 204 and the high-voltage cable more consistent. Therefore, through the joint setting of the simulated cable snow detection mechanism, the interconnection terminal, etc., the staff can remotely control the simulated cable snow detection mechanism through the cable temperature sensor. The simulated cable snow detection mechanism can indirectly detect and calculate the thickness of snow on the high-voltage cable by detecting the snow on the simulated cable sleeve 204. The staff can judge whether the snow needs to be cleared according to the detection results, which can not only prevent the cable from being damaged by excessive snow accumulation, but also effectively avoid unnecessary cleaning. The simulated cable snow detection mechanism can also monitor the weight of snow on the high-voltage cable. When the weight of snow reaches the warning value, the simulated cable snow detection mechanism will also send an alarm to the interconnection terminal to prompt the relevant staff to take corresponding measures in time. In addition, the simulated cable detection mechanism can also adjust the temperature of the simulated cable sleeve 204 according to the cable temperature to improve the synchronization of the simulated cable sleeve 204 and the cable snow accumulation, thereby improving the accuracy of the detection.

[0033] See also Figure 3-5 The heat transfer sleeve 211 is slidably and sealedly connected to the heat transfer rod 210. The top end of the heat transfer rod 210 is lower than the bottom end of the heat transfer core rod 212, so that the heat transfer rod 210 and the heat transfer sleeve 211 will not effectively support the pseudo-cable sleeve 204, thereby preventing the detection of the thickness and weight of the snow from being affected. A cavity is provided inside the heat transfer core rod 212 to reduce the dead weight of the heat transfer core rod 212 and improve the accuracy of the detection. The outer surfaces of the heat transfer rod 210 and the heat transfer sleeve 211 are coated with heat insulation paint. The support box 201 and the partition 202 are made of heat insulation materials to reduce heat loss.

[0034] The second implementation method:

[0035] Figure 7-10A high-voltage cable snow thickness detection device is shown. Different from the first embodiment, the simulated cable snow detection mechanism also includes a freezing detection component, which includes a sealing cylinder 401 fixedly mounted on the mounting plate 101, an electromagnet 402 fixedly mounted in the sealing cylinder 401, a piston plate 403 slidably sealed and connected to the sealing cylinder 401 is arranged above the electromagnet 402, a linkage magnet 404 is fixedly connected to the top of the piston plate 403, an air guide tube 405 is connected to the top of the sealing cylinder 401, a distance sensor 408 is fixedly mounted on the inner wall of the top of the sealing cylinder 401, and the freezing detection component also includes a freezing detection hole 406 opened on the outer wall of the top of the simulated cable sleeve 204, and a freezing detection elastic membrane 406 matching with it is sealed and fixedly connected to the inner wall of the freezing detection hole 406. 07, the top of the air guide pipe 405 passes through the heat transfer core rod 212 and extends to communicate with the frost detection hole 406, the snow detection master control module is electrically connected to the electromagnet 402 and the distance sensor 408, and the snow detection intelligent controller 003 is also provided with a frost detection analysis module, the distance sensor 408 is electrically connected to the frost detection analysis module, and the frost detection analysis module is electrically connected to the snow detection master control module. The staff can also issue an instruction to the snow detection master control module to detect whether the snow is frozen through the interconnection terminal. After receiving the instruction, the snow detection master control module will start the electromagnet 402 and the distance sensor 408. After the electromagnet 402 is started, it will repel the linkage magnet 404. Under the action of the magnetic repulsion, the piston plate 403 will move upward, so that the air above the piston plate 403 will be squeezed and passed through the air guide pipe 4 05 flows into the freezing detection hole 406, causing the air pressure in the freezing detection hole 406 to increase. Under the action of the air pressure, the freezing detection elastic membrane 407 will have a tendency to bulge upward. If the snow is not frozen, the loose snow will not cause too much resistance to the upward bulge deformation of the freezing detection elastic membrane 407, and thus will not cause too much resistance to the upward movement of the piston plate 403, so that the piston plate 403 will move upward to a relatively high position. On the contrary, if the snow is frozen, the resistance to the upward bulge of the freezing detection elastic membrane 407 will increase significantly, and the upward movement of the piston plate 403 will also be hindered, so that the piston plate 403 will stay at a relatively low position. The distance sensor 408 can detect the distance between it and the piston plate 403, and the detection result will be fed back to the freezing detection Analysis module, the freezing detection analysis module can calculate the final upward moving distance of the piston plate 403 through the distance data detected by the distance sensor 408, and then determine whether the snow is frozen. The judgment result will be transmitted to the snow detection master control module, and then sent to the interconnection terminal by the snow detection master control module. After receiving the judgment result, the snow detection master control module will turn off the electromagnet 402 and the distance sensor 408. Since the snow accumulation on the simulated cable sleeve 204 and the high-voltage cable is almost synchronous and consistent, whether the snow on the simulated cable sleeve 204 is frozen also represents whether the snow on the cable is frozen. Therefore, through the setting of the freezing detection component, the simulated cable snow detection mechanism can also detect and determine whether the snow on the high-voltage cable is frozen. If the snow is frozen, it can prompt the staff to take corresponding measures in time.To prevent the cable from being damaged by snow and ice, the air guide tube 405 is a plastic hose to prevent it from affecting the detection of snow thickness and weight.

[0036] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
