Description

Technical Field

[0001] This utility model relates to the field of circuit detection technology, and in particular to a power transmission line fault detection device. Background Technology

[0002] Transmission lines are an important component of the power system. Once a fault occurs, it will seriously affect the safe and stable operation of the system. For example, the "8.14" blackout in the United States and Canada was caused by the lack of effective detection and control of potential faults in overhead transmission lines. Therefore, effective detection, management and maintenance of transmission lines are of great importance.

[0003] Circuit fault detection devices are mostly installed on outdoor poles and towers. When the weather is hot or cold, the equipment inside is easily affected by the ambient temperature, which can affect the normal use of the device. Utility Model Content

[0004] The purpose of this utility model is to provide a power transmission line fault detection device to solve the problem that most circuit fault detection devices are installed on outdoor poles and towers, and the internal equipment is easily affected by the ambient temperature when the weather is hot or cold, thus affecting the normal use of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power transmission line fault detection device, comprising a detection box, and further comprising:

[0006] A heat dissipation mechanism is installed inside the testing chamber and is used to dissipate heat and cool the testing chamber.

[0007] A closing mechanism is installed on the detection box, and the closing mechanism is used as a switch for water cooling.

[0008] A pressure relief mechanism is provided on the detection chamber and is used to release pressure from the gas inside the detection chamber.

[0009] Preferably, the heat dissipation mechanism includes a fan box fixedly installed inside the testing box, a drive shaft rotatably installed through the fan box, the front end of the drive shaft extending outside the testing box, a drive motor fixedly installed on the back of the fan box, the output shaft of the drive motor fixedly connected to the drive shaft, and a plurality of fan blades fixedly installed on the drive shaft.

[0010] Preferably, the front of the testing box has several oblique holes, and a T-shaped hollow box is fixedly installed on the inner wall of the front of the testing box, with the end of the T-shaped hollow box communicating with the bellows.

[0011] Preferably, a cleaning plate is fixedly mounted on the drive shaft, and the back of the cleaning plate is in contact with the detection box.

[0012] Preferably, the closing mechanism includes a temperature-controlled electric telescopic rod fixedly installed on the inner wall of the bottom of the detection box, a C-shaped frame fixedly installed on the output shaft of the temperature-controlled electric telescopic rod, an L-shaped block fixedly installed on the top of the C-shaped frame, a ventilation groove opened on the L-shaped block, and the L-shaped block slidingly penetrating through the T-shaped hollow box.

[0013] Preferably, a collection box is fixedly installed on the top of the detection box, a water outlet is provided on the front of the collection box, an inclined groove is provided on the top of the detection box, and the top of the L-shaped block extends into the collection box.

[0014] Preferably, the pressure relief mechanism includes a rectangular box that is fixedly installed through the detection box. The front of the rectangular box has several air inlets. A T-shaped hollow slider is slidably installed inside the rectangular box. The back of the T-shaped hollow slider extends to the outside of the rectangular box. A limiting spring is fixedly installed on the inner wall of the front of the rectangular box. The end of the limiting spring is fixedly connected to the T-shaped hollow slider. Air outlets are respectively opened at the top and bottom of the T-shaped hollow slider.

[0015] Preferably, a mounting base is fixedly installed at the bottom of the testing box, and a plurality of threaded pins are threaded through the mounting base.

[0016] The beneficial effects of this utility model are as follows:

[0017] In this utility model:

[0018] 1. In hot weather, when the temperature-controlled electric telescopic rod inside the testing chamber detects an excessively high temperature, it will activate the drive motor. The drive motor drives the drive shaft to rotate, which in turn drives several fan blades. These fan blades draw in outside air through the oblique holes and the T-shaped hollow box and blow it into the testing chamber. As air continues to enter the testing chamber, the air pressure increases. The air then enters the rectangular box through the air inlet and pushes the T-shaped hollow slider away from the rectangular box. At this time, the limit spring is stretched and deformed. When the air outlet on the T-shaped hollow slider leaves the rectangular box, the air that has entered the testing chamber will be expelled. To achieve heat dissipation, the drive shaft rotates, which in turn drives the cleaning plate to rotate. The cleaning plate cleans the dust on the surface of the inclined holes, preventing blockage and ensuring effective heat dissipation. Correspondingly, the temperature-controlled electric telescopic rod also drives the C-shaped frame to rise, which in turn drives the L-shaped block to rise. The ventilation slots on the L-shaped block allow air to enter the T-shaped hollow box, ensuring air circulation. Conversely, in colder weather, the temperature-controlled electric telescopic rod remains stationary, and the drive motor does not actively dissipate heat. In this case, the L-shaped block also blocks the T-shaped hollow box, keeping the testing box sealed and preventing the temperature inside the testing box from becoming too low and affecting the normal operation of the device.

[0019] 2. In hot weather, rain may occur. As the L-shaped baffle rises, it blocks the water outlet, and the rainwater flows into the collection box for collection. The rainwater stored in the collection box absorbs heat through heat transfer between the detection box and the collection box, thereby enhancing the heat dissipation effect inside the detection box. When the temperature is too low, the temperature-controlled electric telescopic rod drives the L-shaped baffle to descend. At this time, the water outlet opens, and the rainwater flows out from the water outlet along the inclined channel. The rainwater flows through several inclined holes to wash away the dust remaining on the cleaning plate, improving the cleaning effect of the cleaning plate. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figure 1-5The transmission line fault detection device shown includes a detection box 1, and further includes: a heat dissipation mechanism disposed inside the detection box 1 for cooling the detection box 1; a closing mechanism disposed on the detection box 1 for switching on water cooling; and a pressure relief mechanism disposed on the detection box 1 for releasing pressure from the gas inside the detection box 1. The heat dissipation mechanism includes a fan box 101 fixedly installed inside the detection box 1, a drive shaft 102 rotatably mounted through the fan box 101, the front end of the drive shaft 102 extending outside the detection box 1, a drive motor 103 fixedly mounted on the back of the fan box 101, the output shaft of the drive motor 103 fixedly connected to the drive shaft 102, and several fan blades 104 fixedly mounted on the drive shaft 102. Several oblique holes 105 are opened on the front of the detection box 1, and a T-shaped hollow box 106 is fixedly mounted on the inner wall of the front of the detection box 1, the end of the T-shaped hollow box 106 communicating with the fan box 101. A cleaning plate 107 is fixedly mounted on the drive shaft 102, and the back of the cleaning plate 107 is in contact with the detection box 1;

[0028] In hot weather, when the temperature-controlled electric telescopic rod 108 inside the detection chamber 1 detects an excessively high temperature, it activates the drive motor 103. The drive motor 103 drives the drive shaft 102 to rotate, which in turn drives several fan blades 104 to rotate. The fan blades 104 draw in outside air through the oblique hole 105 and the T-shaped hollow box 106 and blow it into the detection chamber 1. As air is continuously input into the detection chamber 1, the air pressure increases. The air enters the rectangular box 203 through the air inlet 204 and slides away from the rectangular box 203, pushing against the T-shaped hollow slider 205. At this time, the limit spring 206 is stretched and deformed. When the air outlet 207 on the T-shaped hollow slider 205 leaves the rectangular box 203, the air entering the detection chamber 1... The cooling effect is achieved by discharging the dust. During the rotation of the drive shaft 102, the cleaning plate 107 will rotate, and the cleaning plate 107 will clean the dust on the surface of the inclined hole 105 to prevent the inclined hole 105 from being blocked and affecting the cooling effect. Correspondingly, the temperature-controlled electric telescopic rod 108 will also drive the C-shaped frame 109 to rise, and the C-shaped frame 109 will drive the L-shaped stop 110 to rise. The ventilation slot on the L-shaped stop 110 will enter the T-shaped hollow box 106 to ensure air circulation. Conversely, in colder weather, the temperature-controlled electric telescopic rod 108 will remain stationary. At this time, the drive motor 103 will not actively dissipate heat. At this time, the L-shaped stop 110 will also block the T-shaped hollow box 106 to keep the detection box 1 in a sealed state, so as to prevent the temperature inside the detection box 1 from being too low and affecting the normal operation of the device.

[0029] A collection box 2 is fixedly installed on the top of the testing box 1. A water outlet 201 is provided on the front of the collection box 2. A sloping groove 202 is provided on the top of the testing box 1. The top of the L-shaped baffle 110 extends into the collection box 2. The pressure relief mechanism includes a rectangular box 203 fixedly installed through the testing box 1. Several air inlets 204 are provided on the front of the rectangular box 203. A T-shaped hollow slider 205 is slidably installed inside the rectangular box 203. The back of the T-shaped hollow slider 205 extends outside the rectangular box 203. A limiting spring 206 is fixedly installed on the inner wall of the front of the rectangular box 203. The end of the limiting spring 206 is fixedly connected to the T-shaped hollow slider 205. Air outlets 207 are provided at the top and bottom of the T-shaped hollow slider 205. A mounting base 208 is fixedly installed at the bottom of the testing box 1. Several threaded nails 209 are threaded through the mounting base 208.

[0030] In hot weather, rain may occur. As the L-shaped baffle 110 rises, it blocks the water outlet 201, and the rainwater flows into the collection box 2 for collection. The rainwater stored in the collection box 2 absorbs heat through heat transfer between the detection box 1 and the collection box 2, thereby enhancing the heat dissipation effect inside the detection box 1. When the temperature is too low, the temperature-controlled electric telescopic rod 108 drives the L-shaped baffle 110 to descend. At this time, the water outlet 201 opens, and the rainwater flows out from the water outlet 201 along the inclined groove 202. The rainwater flows through several inclined holes 105 to wash away the dust remaining on the cleaning plate 107, improving the cleaning effect of the cleaning plate 107.

[0031] The working principle of the power transmission line fault detection device provided by this utility model is as follows:

[0032] In hot weather, when the temperature-controlled electric telescopic rod 108 inside the detection chamber 1 detects an excessively high temperature, it activates the drive motor 103. The drive motor 103 drives the drive shaft 102 to rotate, which in turn drives several fan blades 104 to rotate. The fan blades 104 draw in outside air through the oblique hole 105 and the T-shaped hollow box 106 and blow it into the detection chamber 1. As air is continuously input into the detection chamber 1, the air pressure increases. The air enters the rectangular box 203 through the air inlet 204 and slides away from the rectangular box 203, pushing against the T-shaped hollow slider 205. At this time, the limit spring 206 is stretched and deformed. When the air outlet 207 on the T-shaped hollow slider 205 leaves the rectangular box 203, the air entering the detection chamber 1... The cooling effect is achieved by discharging the dust. During the rotation of the drive shaft 102, the cleaning plate 107 will rotate, and the cleaning plate 107 will clean the dust on the surface of the inclined hole 105 to prevent the inclined hole 105 from being blocked and affecting the cooling effect. Correspondingly, the temperature-controlled electric telescopic rod 108 will also drive the C-shaped frame 109 to rise, and the C-shaped frame 109 will drive the L-shaped stop 110 to rise. The ventilation slot on the L-shaped stop 110 will enter the T-shaped hollow box 106 to ensure air circulation. Conversely, in colder weather, the temperature-controlled electric telescopic rod 108 will remain stationary. At this time, the drive motor 103 will not actively dissipate heat. At this time, the L-shaped stop 110 will also block the T-shaped hollow box 106 to keep the detection box 1 in a sealed state, so as to prevent the temperature inside the detection box 1 from being too low and affecting the normal operation of the device.

[0033] In hot weather, rain may occur. As the L-shaped baffle 110 rises, it blocks the water outlet 201, and the rainwater flows into the collection box 2 for collection. The rainwater stored in the collection box 2 absorbs heat through heat transfer between the detection box 1 and the collection box 2, thereby enhancing the heat dissipation effect inside the detection box 1. When the temperature is too low, the temperature-controlled electric telescopic rod 108 drives the L-shaped baffle 110 to descend. At this time, the water outlet 201 opens, and the rainwater flows out from the water outlet 201 along the inclined groove 202. The rainwater flows through several inclined holes 105 to wash away the dust remaining on the cleaning plate 107, improving the cleaning effect of the cleaning plate 107.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
