Description

Technical Field

[0001] This application relates to the field of heat dissipation testing technology for distribution boxes, and in particular to an automated testing device for distribution boxes. Background Technology

[0002] A distribution box, also known as a distribution cabinet, electrical distribution box, or power distribution box, is a device in a power system used to distribute and protect electrical energy. It distributes power from the power source to various electrical devices or loads. Distribution boxes are widely used in industrial, commercial, and residential buildings to ensure a safe and stable power supply and improve electrical safety through equipped protective devices. During use, due to the large number of electronic components inside the distribution box, its internal temperature can become high over time, necessitating the use of cooling devices to dissipate heat.

[0003] During the development of heat sinks, it is impossible to accurately and comprehensively test their heat dissipation performance, resulting in heat sinks failing to meet the actual heat dissipation requirements of equipment such as servers. Currently, it is difficult to test the heat dissipation performance of power distribution boxes, making it difficult to ensure that the internal temperature of the power distribution box remains below the set temperature during prolonged use. This can easily lead to damage to the electronic components inside the power distribution cabinet, and therefore needs to be improved. Utility Model Content

[0004] In order to test the heat dissipation performance of the accessory box radiator, this application provides an automated testing device for distribution boxes.

[0005] The automated testing device for distribution boxes provided in this application adopts the following technical solution:

[0006] An automated testing device for a distribution box includes a housing and a testing mechanism. Two support plates are fixedly connected to the front of the housing. Two electric heating rods are fixedly connected to the side of the two support plates that are close to each other. The testing mechanism is located outside the housing and includes two mounting brackets respectively installed on the left and right sides of the housing. A control rod is slidably connected to the inner wall of each mounting bracket. A set of positioning holes is formed on the side of the two control rods that are far apart from each other. Threaded holes are formed on the side of the two mounting brackets that are far apart from each other. A threaded positioning rod is threadedly connected to the inner wall of each threaded hole. The ends of the two threaded positioning rods that are close to each other extend into the interior of two of the positioning holes. A temperature sensor is fixedly connected to the top of each control rod. A controller and an alarm are fixedly connected to the inner wall of the housing.

[0007] By adopting the above technical solution, the electric heating rod can be controlled by a controller and an alarm, enabling it to heat up and raise the internal temperature of the distribution box. This simulates the internal temperature of the distribution box, and a temperature sensor can detect changes in the internal temperature. The temperature is monitored as the heat dissipation mechanism of the distribution box dissipates heat, and the controller can record the rate of temperature drop. This allows for testing the heat dissipation performance of the distribution box, ensuring that the electronic components inside the distribution box are kept at a suitable temperature and preventing damage to the electronic components due to high temperatures.

[0008] Optionally, a first limiting block is fixedly connected to the bottom surface of each control lever, and a second limiting block is fixedly connected to the front surface of each control lever.

[0009] By adopting the above technical solution, the cooperation between the first limit block and the second limit block limits the control rod and prevents the control rod from separating from the card seat.

[0010] Optionally, two baffles are fixedly connected to each of the left and right sides of the housing, and the sides of the two sets of baffles that are close to each other are fixedly connected to the front and back of the control lever, respectively.

[0012] Optionally, a protective bend plate is fixedly connected to the front of the housing, and the front of the protective bend plate has two sets of through holes arranged at equal intervals.

[0013] By adopting the above technical solution, the protective bend plate isolates the electric heating rod, preventing workers from accidentally touching the heat source, and the through hole allows heat to be discharged outward.

[0014] Optionally, a U-shaped plate is fixedly connected to the bottom surface of the protective bend plate, and the side of the U-shaped plate away from the protective bend plate is fixedly connected to the bottom surface of the housing.

[0015] By adopting the above technical solution, the U-shaped plate supports the protective bend plate, increasing the stability of the protective bend plate.

[0016] Optionally, a handle is provided on the top of the housing, and the bottom surface of the handle is fixedly connected to the upper surface of the housing.

[0017] By adopting the above technical solution, the handle makes it easy for staff to carry the device, making it convenient to transport.

[0018] Optionally, a mounting plate is fixedly connected to the upper surface of the housing, and two mounting holes are fixedly opened on the front side of the mounting plate.

[0019] By adopting the above technical solution, the casing is installed through the mounting plate and mounting holes to prevent the casing from shaking.

[0020] Optionally, the front of the housing is fixedly connected to two mounting bases, and the sides of the two mounting bases that are close to each other are fixedly connected to the sides of the two support plates that are far from each other.

[0021] By adopting the above technical solution, the fixing seat reinforces the support plate, improves the stability of the fixing seat, and prevents the fixing seat from becoming loose.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The electric heating rod can be controlled by a controller and an alarm to heat up the distribution box, simulating the internal temperature. A temperature sensor detects temperature changes within the distribution box, monitoring the temperature as the heat dissipation mechanism expels heat.

This ensures that the internal electronic components are kept at a suitable temperature, preventing damage due to overheating.

[0024] 2. The cooperation of the first and second limit blocks limits the control lever to prevent it from separating from the card seat;

[0025] 3. The protective bend plate isolates the electric heating rod to prevent workers from accidentally touching the heat source, and the through holes allow heat to escape. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses an automated testing device for distribution boxes. (Refer to...) Figure 1 and Figure 2 An automated testing device for a distribution box includes a housing 1. Two support plates 101 are fixedly connected to the front of the housing 1. Two electric heating rods 102 are fixedly connected to the side of the two support plates 101 that are close to each other. Two fixing seats 3 are fixedly connected to the front of the housing 1. The side of the two fixing seats 3 that are close to each other is fixedly connected to the side of the two support plates 101 that are far apart from each other. The fixing seats 3 can reinforce the support plates 101, improve the stability of the fixing seats 3, and prevent the fixing seats 3 from loosening. A mounting plate 6 is fixedly connected to the upper surface of the housing 1. Two mounting holes 601 are fixedly opened on the front of the mounting plate 6. The housing 1 can be installed through the mounting plate 6 and the mounting holes 601 to prevent the housing 1 from shaking.

[0033] Reference Figure 2 and Figure 4 A testing mechanism 2 is installed on the exterior of the housing 1. The testing mechanism 2 includes two mounting bases 201 respectively installed on the left and right sides of the housing 1. A control rod 202 is slidably connected to the inner wall of each mounting base 201. A set of positioning holes 203 is provided on the side of each control rod 202 that is far apart from each other. Threaded holes 204 are provided on the side of each mounting base 201 that is far apart from each other. A threaded positioning rod 205 is threadedly connected to the inner wall of each threaded hole 204. The ends of the two threaded positioning rods 205 that are close to each other extend into the interior of two of the positioning holes 203.

[0034] Reference Figure 2 and Figure 3 A temperature sensor 206 is fixedly connected to the top of each control lever 202, a controller 210 is fixedly connected to the inner wall of the housing 1, and an alarm 209 is fixedly connected to the inner wall of the housing 1.

[0035] In use, first move the device inside the distribution box, then fix it with the mounting plate 6 to prevent it from shaking. Next, rotate the threaded positioning rod 205 to move it out of the positioning hole 203, and push the control rod 202 upward to move the temperature sensor 206 to the top of the distribution box. Rotate the threaded positioning rod 205 again to re-enter the positioning hole 203 through the threaded hole 204, thus positioning the control rod 202.

[0036] The controller 210 activates the electric heating rod 102, heating the surrounding area and simulating a high internal temperature within the distribution box. Simultaneously, the temperature sensor 206 monitors the internal temperature. When the set temperature is reached, the controller 210 shuts off the electric heating rod 102 and activates the distribution box's cooling mechanism to dissipate heat. The temperature sensor 206 monitors the temperature; if it falls below the set temperature, a signal is sent to the controller 210, which records the time the electric heating rod 102 is shut off and the time the temperature remains below the set value. If the time exceeds the set duration, the alarm 209 is activated to alert personnel that the distribution box's cooling performance is inadequate.

[0037] Reference Figure 1 Each control lever 202 has a first limiting block 207 fixedly connected to its bottom surface, and a second limiting block 208 fixedly connected to its front surface. Through the cooperation of the first limiting block 207 and the second limiting block 208, the control lever 202 can be limited to prevent it from separating from the card holder 201.

[0038] Reference Figure 1 and Figure 2 Two retaining strips 4 are fixedly connected to both the left and right sides of the housing 1. The sides of the two sets of retaining strips 4 that are close to each other are fixedly connected to the front and back of the control lever 202, respectively. The retaining strips 4 can limit the control lever 202 and prevent it from shaking during use.

[0039] Reference Figure 1 and Figure 2 A protective bend plate 5 is fixedly connected to the front of the housing 1. The protective bend plate 5 has two sets of through holes 501 arranged at equal intervals on its front. The protective bend plate 5 and the through holes 501 can isolate the electric heating rod 102 to prevent workers from accidentally touching the heat source, and the through holes 501 can allow heat to be discharged to the outside.

[0040] Reference Figure 1 and Figure 3A U-shaped plate 502 is fixedly connected to the bottom surface of the protective bending plate 5. The side of the U-shaped plate 502 away from the protective bending plate 5 is fixedly connected to the bottom surface of the housing 1. The U-shaped plate 502 can support the protective bending plate 5 and increase the stability of the protective bending plate 5.

[0041] Reference Figure 1 and Figure 2 A handle 7 is provided on the top of the housing 1. The bottom surface of the handle 7 is fixedly connected to the upper surface of the housing 1. The handle 7 makes it convenient for staff to carry the device, making it easy to carry.

[0042] The implementation principle of the automated testing device for a distribution box according to this application embodiment is as follows: First, the device is moved inside the distribution box and then fixed by the mounting plate 6 to prevent shaking. Next, by rotating the threaded positioning rod 205, it moves out of the positioning hole 203, pushing the control rod 202 upwards, causing the temperature sensor 206 to move upwards to the top of the distribution box. Rotating the threaded positioning rod 205 again allows it to re-enter the positioning hole 203 through the threaded hole 204, positioning the control rod 202. Then, the controller 210 activates the electric heating rod 102, heating the surrounding area and raising the internal temperature of the distribution box, simulating the high temperature inside the distribution box. Simultaneously, temperature sensor 206 senses the internal temperature of the distribution cabinet. When the temperature reaches the set temperature, controller 210 shuts off the electric heating rod 102 and then activates the heat dissipation mechanism of the distribution box to cool the interior. Temperature sensor 206 senses the temperature, and when the temperature falls below the set temperature, a signal is sent to controller 210, which records the time the electric heating rod 102 is shut off and the time the temperature falls below the set value. If the time exceeds the set duration, alarm 209 is activated to alert personnel that the heat dissipation performance of the distribution box is substandard.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
