Description

Technical Field

[0001] The present invention relates to the technical field of power detection devices, and in particular to a power detection device with good heat dissipation effect. Background Art

[0002] Power detection devices are key equipment for ensuring the safe and stable operation of power systems. They are primarily used to monitor system parameters such as voltage, current, power, and power quality in real time, and to provide early warnings of potential faults. Their operating principle is to collect power signals through sensors such as current transformers and voltage transformers. After signal conditioning and analog-to-digital conversion, the data is analyzed and processed using digital signal processing technology, and the results are ultimately displayed or uploaded to a monitoring system. In practical applications, these devices are widely deployed in substations, distribution rooms, and industrial power equipment. Operations and maintenance personnel can obtain power parameters through the device panel or remote monitoring platform, allowing them to promptly identify and resolve power anomalies.

[0014] The beneficial effects are: 1. The power detection device with good heat dissipation effect, through the cooperation of the air cooling component and the heat dissipation component, enables the fan to promote the circulation of air inside the shell. After the heat is absorbed by multiple fixed plates, the air discharges the heat from the shell through contact with the air; through the arrangement of multiple pairs of swinging plates, the multiple pairs of swinging plates can absorb part of the heat of the fixed plates connected to them, and promote the dissipation of heat through opening and closing movements.

[0020] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other implementations obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0021] Example 1 See also Figure 1 - Figure 6, an electric power detection device with good heat dissipation effect, includes a shell 1 and a detector 2 installed therein, and also includes: an air cooling component 4 for air cooling and heat dissipation; the air cooling component 4 includes a motor 41, which is installed in the shell 1, and the output end of the motor 41 is fixedly connected to a transmission wheel 42, and a mounting seat 44 is fixedly installed in the shell 1. The inner wall of the mounting seat 44 is rotatably connected to a fan 45, and a belt 43 is connected between the fan 45 and the transmission wheel 42. Heat dissipation ports 3 are respectively installed on both sides of the shell 1. After the motor 41 is started, it drives the transmission wheel 42 to rotate. The transmission wheel 42 drives the fan 45 to rotate on the mounting seat 44 through the belt 43. When the fan 45 rotates, it can drive air flow, so that the air enters from the heat dissipation port 3 close to the fan 45 and is discharged through the heat dissipation port 3 far away from the fan 45, so that the external air continuously passes through the inside of the shell 1, thereby taking away the heat inside the shell 1, achieving the effect of air cooling and cooling.

[0022] Furthermore, the heat dissipation component 5 is used to accelerate the heat dissipation of the detector 2; the heat dissipation component 5 includes a heat conducting plate 51, which is fixedly connected to the bottom of the detector 2, and two groups of fixing plates 52 are fixedly connected to the heat conducting plate 51, and one group of fixing plates 52 includes multiple pairs of fixing plates 52, and multiple pairs of fixing plates 52 are respectively rotatably connected to multiple pairs of swinging plates 510. The heat conducting plate 51 can absorb the heat inside the detector 2, and the heat conducting plate 51, the fixing plates 52 and the swinging plates 510 are all made of materials with high thermal conductivity. The two groups of fixing plates 52 can absorb the heat of the heat conducting plate 51, and there are gaps between the multiple pairs of fixing plates 52. When air flows over the surface of the two groups of fixing plates 52, it can contact the multiple pairs of fixing plates 52 and take away the heat emitted by the fixing plates 52, thereby accelerating the heat dissipation efficiency of the detector 2.

[0023] Furthermore, the heat dissipation assembly 5 also includes a slider 54, which is slidably installed in the housing 1. A slot rod 55 is fixedly connected to the slider 54, a cam 53 is fixedly connected to the transmission wheel 42, a slide 56 is slidably connected to the heat conducting plate 51, a slide groove is provided on the slot rod 55, and a roller is provided on the cam 53. The roller of the cam 53 is slidably connected to the slide groove of the slot rod 55. When the cam 53 rotates, the roller can convert the rotation into reciprocating motion by cooperating with the slide groove. The slide 56 is fixedly connected to the slider 54. When the cam 53 rotates, the slot rod 55 is driven to move back and forth through the roller. The slot rod 55 drives the slide 56 to move back and forth through the slider 54. A second connecting rod 59 is hinged on the swinging piece 510, and a sliding column 58 is hinged between the second connecting rods 59 on a pair of swinging pieces 510. The sliding column 58 is limited It can only slide left and right. The sliding column 58 is slidably connected to the heat conducting plate 51. A first connecting rod 57 is hinged on the sliding column 58. The first connecting rod 57 is hinged to the slide 56. Taking one pair of swinging plates 510 as an example, the sliding column 58 can drive the two swinging plates 510 to swing back and forth through the two second connecting rods 59 when moving back and forth left and right, so that the two swinging plates 510 can continuously open and close, so that the multiple pairs of swinging plates 510 under the heat conducting plate 51 can continuously open and close. The multiple pairs of swinging plates 510 can absorb part of the heat from the fixed plates 52 connected thereto, and promote the dissipation of heat through the opening and closing movement. The multiple pairs of swinging plates 510 can also continuously fan the air near the multiple fixed plates 52 when performing the opening and closing movement, thereby increasing the contact area between the fixed plates 52 and the air, thereby promoting the dissipation of heat at the fixed plates 52 and accelerating the heat dissipation efficiency.

[0024] Also, see Figure 4 - Figure 7 The heat dissipation assembly 5 also includes two spoilers 511 and two triangular blocks 512. The two spoilers 511 are hinged in the shell 1. The two spoilers 511 are mirror-imaged. The two triangular blocks 512 are fixedly connected to the slide 56. The two triangular blocks 512 slide in contact with the two spoilers 511 respectively during movement. When the two triangular blocks 512 slide in contact with the two spoilers 511, the two spoilers 511 are lifted up by their inclined surfaces. When the two triangular blocks 512 are not in contact with the two spoilers 511, the two spoilers 511 are reset by gravity, causing the two spoilers 511 to swing back and forth up and down, thereby promoting the longitudinal flow of air in the shell 1, so that the air in the shell 1 can contact various parts of the interior of the shell 1 more evenly during circulation, thereby bringing out the heat from various parts of the shell 1.

[0025] It is worth noting that see Figure 2 、 Figure 8 - Figure 12, the water-cooling assembly 6 is used to further improve the heat dissipation effect of the air-cooling assembly 4; the water-cooling assembly 6 includes a first liquid pipe 61, a heat dissipation pipe group 62, a second liquid pipe 63, an elastic pipe 64 and a third liquid pipe 65. The first liquid pipe 61, the heat dissipation pipe group 62, the second liquid pipe 63 and the third liquid pipe 65 are all fixedly installed in the housing 1 through mounting parts. The elastic pipe 64 is fixedly connected between the second liquid pipe 63 and the third liquid pipe 65. The heat dissipation pipe group 62 is provided with an inlet and an outlet. One end of the first liquid pipe 61 is connected to the mounting seat 44. The first liquid pipe 61 is connected to the mounting seat 44. The other end of the second liquid pipe 61 is connected to the inlet of the heat dissipation tube group 62, the end of the second liquid pipe 63 away from the elastic tube 64 is connected to the outlet of the heat dissipation tube group 62, and the end of the third liquid pipe 65 away from the elastic tube 64 is rotatably connected to the fan 45 through a connecting piece. Cooling liquid is filled in the first liquid pipe 61, the heat dissipation tube group 62, the second liquid pipe 63, the elastic tube 64, the third liquid pipe 65, the first flow channel 66 and the second flow channel 67. The heat dissipation tube group 62 is provided with a plurality of serpentine heat dissipation pipes, which can promote the coolant therein to dissipate heat, thereby reducing the temperature of the coolant.

[0026] It is worth mentioning that the fan 45 includes a central axis, a plurality of blades and an annular ring. The plurality of blades are mounted on the central axis. The annular ring is connected to one end of the plurality of blades away from the central axis. A first flow channel 66 is provided between the central axis, the plurality of blades and the annular ring. The first flow channel 66 is communicated with the interior of the third liquid pipe 65. A second flow channel 67 is provided in the mounting seat 44. The second flow channel 67 is communicated with the first flow channel 66. The second flow channel 67 is also communicated with the interior of the first liquid pipe 61. The air entering the housing 1 first contacts the fan 45. The fan 45 uses the coolant inside it to absorb heat in the air and cool the air. It is worth noting that the water cooling assembly 6 also includes a mounting frame 68, two support rods 69, a push roller 610 and a curved surface block 611. The mounting frame 68 is fixedly mounted on the slider 54. The two support rods 69 are hinged on the mounting frame 68. The push roller 610 is rotatably mounted between the two support rods 69. A ratchet and pawl mechanism is provided inside the connection between the push roller 610 and the two support rods 69. The push roller 610 is unidirectionally limited by the ratchet and pawl. The ratchet and pawl are conventional unidirectional rotation limiting structures. The specific principle and structure are not described in detail. The arc block 611 is fixedly connected to the slider 54. The elastic tube 64 is located between the push roller 610 and the arc block 611. There is a large friction between the push roller 610 and the elastic tube 64. A spring 612 is connected between the support rod 69 and the mounting bracket 68. The elastic tube 64 is elastic. The springs 612 on the two support rods 69 can keep the push roller 610 in contact with the elastic tube 64. When the push roller 610 moves closer to the third liquid pipe 65, the push roller 610 is pushed. The roller 610 cannot rotate, and the two support rods 69 swing downward due to the friction between the push roller 610 and the elastic tube 64, so that the two support rods 69 support the push roller 610 downward. The push roller 610 squeezes the elastic tube 64 to deform the elastic tube 64. During this process, the arc block 611 presses below the deformation position of the elastic tube 64, thereby achieving the effect of flattening the contact area between the elastic tube 64 and the push roller 610. When the push roller 610 moves close to the third liquid tube 65, the push roller 610 pushes the coolant in the elastic tube 64 into the third liquid tube 65. When the push roller 610 moves close to the second liquid tube 63, the push roller 610 can roll along the outer wall of the elastic tube 64. The push roller 610 does not cause the elastic tube 64 to deform, thereby achieving the technical effect of allowing the coolant to circulate in the first liquid tube 61, the heat dissipation tube group 62, the second liquid tube 63, the elastic tube 64, the third liquid tube 65, the first flow channel 66, and the second flow channel 67.

[0027] With the above structure, the working principle of this case is that after the motor 41 is started, it drives the transmission wheel 42 to rotate. The transmission wheel 42 drives the fan 45 to rotate on the mounting base 44 through the belt 43. When the fan 45 rotates, it can drive the air flow, so that the air enters from the heat dissipation port 3 close to the fan 45, and then is discharged through the heat dissipation port 3 away from the fan 45, so that the external air continuously passes through the inside of the shell 1, thereby taking away the heat inside the shell 1, achieving the effect of air cooling. The heat conducting plate 51 can absorb the heat inside the detector 2. The heat conducting plate 51, the fixed plate 52 and the swing plate 510 are all made of high thermal conductivity materials. The two groups of fixed plates 52 can absorb the heat of the heat conducting plate 51, and there are gaps between multiple pairs of fixed plates 52. When the air flows through the surface of the two groups of fixed plates 52, it can contact multiple pairs of fixed plates 52 and take away the heat emitted by the fixed plates 52, thereby accelerating the heat dissipation efficiency of the detector 2.

[0028] When the transmission wheel 42 rotates, it drives the cam 53 to rotate. When the cam 53 rotates, the roller can convert the rotation into reciprocating motion by cooperating with the slide groove, so that when the cam 53 rotates, the groove rod 55 is driven by the roller to move back and forth, the groove rod 55 drives the slider 54 to move back and forth, and the slider 54 drives the slide 56 to move back and forth. The slide post 58 is limited and can only slide left and right. When the slide 56 moves back and forth, it can drive multiple slide posts 58 to move horizontally through multiple first connecting rods 57. The slide 56 is located between the two rows of fixed plates 52. The multiple slide posts 58 are respectively located on the side of the multiple pairs of fixed plates 52 close to the slide 56, with one of them Taking the swinging piece 510 as an example, when the sliding column 58 moves back and forth left and right, it can drive the two swinging pieces 510 to swing back and forth through the two second connecting rods 59, so that the two swinging pieces 510 can continuously open and close, so that the multiple pairs of swinging pieces 510 under the heat conduction plate 51 can continuously open and close. The multiple pairs of swinging pieces 510 can absorb part of the heat of the fixed piece 52 connected to it, and promote the dissipation of heat through opening and closing movement. When the multiple pairs of swinging pieces 510 open and close, they can also continuously fan the air near the multiple fixed pieces 52, increase the contact area between the fixed piece 52 and the air, thereby promoting the dissipation of heat at the fixed piece 52 and accelerating the heat dissipation efficiency.

[0029] When the slide 56 moves back and forth, it drives the two triangular blocks 512 to move back and forth. During the movement, the two triangular blocks 512 respectively come into sliding contact with the bottom of the two spoilers 511, so that the two triangular blocks 512 use their inclined surfaces to lift the two spoilers 511. When the two triangular blocks 512 are not in contact with the two spoilers 511, the two spoilers 511 are reset by gravity, so that when the slide 56 moves back and forth, it can also use the two triangular blocks 512 to drive the two spoilers 511 to swing back and forth. The opening and closing movement of multiple pairs of swinging pieces 510 can promote the horizontal flow of air in the shell 1, while the up and down reciprocating swing of the two spoilers 511 can promote the longitudinal flow of air in the shell 1, so that the air in the shell 1 can more evenly contact various parts of the interior of the shell 1 during circulation, thereby bringing out heat from various parts of the shell 1.

[0030] The first liquid pipe 61, the heat dissipation pipe group 62, the second liquid pipe 63, the elastic pipe 64, the third liquid pipe 65, the first flow channel 66 and the second flow channel 67 are filled with cooling liquid. When the slider 54 moves back and forth, it drives the mounting frame 68 to move back and forth. The mounting frame 68 drives the push roller 610 to move back and forth through two support rods 69. The springs 612 on the two support rods 69 can keep the push roller 610 in contact with the elastic pipe 64. The elasticity of the spring 612 is relatively small, so that the push roller 610 only keeps in contact with the elastic pipe 64 without causing the elastic pipe 64 to deform. When the push roller 610 moves back and forth, the push roller 610 is limited in one direction by the ratchet pawl, and the push roller 610 There is a large friction force between the push roller 610 and the elastic tube 64. Therefore, when the push roller 610 moves toward the second liquid pipe 63, the push roller 610 can roll along the outer wall of the elastic tube 64, and the push roller 610 does not cause the elastic tube 64 to deform. When the push roller 610 moves toward the third liquid pipe 65, the push roller 610 cannot rotate, and the two support rods 69 are affected by the friction force between the push roller 610 and the elastic tube 64 and swing downward, so that the two support rods 69 support the push roller 610 downward, and the push roller 610 squeezes the elastic tube 64 to deform the elastic tube 64. In this process, the arc block 611 presses against the bottom of the deformation position of the elastic tube 64, thereby achieving elastic The contact portion between the tube 64 and the pushing roller 610 is flattened. When the pushing roller 610 moves close to the third liquid tube 65, the pushing roller 610 pushes the coolant in the elastic tube 64 to the third liquid tube 65. When the pushing roller 610 moves close to the second liquid tube 63 again, the pushing roller 610 rolls again, and the two support rods 69 no longer support the pushing roller 610 downward. The elastic tube 64 is reset by its own elastic force. When the pushing roller 610 moves close to the second liquid tube 63, the coolant in the elastic tube 64 does not flow, thereby achieving the goal of the coolant being able to flow through the first liquid tube 61, the heat dissipation tube group 62, the second liquid tube 63, the elastic tube 64, the third liquid tube 65, the first flow channel 66 and the second liquid tube 65. The technical effect of the circulation flow in the second flow channel 67 is that the air entering the shell 1 first contacts the fan 45. The fan 45 uses the coolant inside it to absorb the heat in the air and cool the air, so that the air can absorb more heat after entering the shell 1. When the coolant flows through the heat dissipation pipe group 62, the heat dissipation pipe group 62 is provided with a plurality of serpentine heat dissipation pipes, which can promote the coolant inside it to dissipate heat, thereby reducing the temperature of the coolant and maintaining the heat exchange effect of the coolant, avoiding the situation where the temperature of the air entering the shell 1 is high due to the high external air temperature when used in a high temperature environment, thereby affecting the discharge of heat and causing poor heat dissipation effect.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
