Description

Technical Field

[0001] The present invention relates to the technical field of power cabinets, in particular to a power cabinet that facilitates heat dissipation. Background Art

[0002] As the name suggests, a power cabinet refers to an object used to contain and protect electrical equipment. In modern power grids, electrical equipment is an important component of the grid. Therefore, a large number of power cabinets are needed to contain and protect the electrical equipment throughout the grid. When the power cabinet is in use, the electronic components inside it generate a large amount of heat. If the heat is not dissipated inside the power cabinet, it is easy for the heat to accumulate and damage the electronic components. In the prior art, power cabinets usually use cooling fans to draw external air into the inner cavity of the power cabinet to dissipate heat from the heat-generating components inside the power cabinet. However, the internal space of the power cabinet is usually large, and the airflow drawn into the inner cavity of the power cabinet by the cooling fan gradually disperses in all directions. This makes the drawn airflow unable to act well on the main heat-generating components, thereby limiting the heat dissipation efficiency of the cooling fan for the main heat-generating components. In addition, the inner cavity of the power cabinet lacks a complete airflow path, making it difficult for the airflow carrying the heat of the main heat-generating components to be evacuated to the outside of the power cabinet, which can easily cause heat accumulation in the main heat-generating components. Therefore, the present invention provides a power cabinet that is easy to dissipate heat. Summary of the Invention

By connecting the action of the staff closing the cabinet door 2 with the telescopic movement of the outer sleeve 10, when the cabinet door 2 is completely closed, the inner sleeve 11 is close to the main heating device. Under the action of the heat dissipation fan 17, the external airflow directly acts on the main heating device in a direct blowing manner, which makes the inhaled airflow very It has a good effect on the main heating components; in addition, when the cabinet door 2 is opened, the inner sleeve 11 is retracted into the outer sleeve 10 under the action of the elastic force of the telescopic component 5 itself, which is convenient for subsequent staff to inspect and repair the components inside the cabinet 1; in addition, under the action of the auxiliary heat dissipation component 19, a complete air flow path is formed inside the cabinet 1, and the air flow carrying the heat of the main heating components is quickly evacuated to the outside of the cabinet 1 along the air flow path, which reduces the residence time of heat inside the cabinet 1, thereby making it less likely for heat from the main heating components to accumulate.

[0030] Furthermore, the telescopic assembly 5 includes a sliding rod 51 slidably arranged on the side wall of the shell 4, and the sliding rod 51 is located on one side of the inner cavity of the shell 4 and is fixedly connected to a circular plate 52. A spring 53 is wound around the rod body of the sliding rod 51, and the spring 53 is connected between the circular plate 52 and the side wall of the inner cavity of the shell 4. When the staff closes the cabinet door 2, the side of the sliding rod 51 away from the cabinet door 2 abuts against the baffle 3. As the cabinet door 2 continues to close, the side of the sliding rod 51 away from the cabinet door 2 continuously moves toward the inner cavity of the shell 4 under the action of the baffle 3, so that the sliding rod 51 drives the circular plate 52 to move, and the circular plate 52 drives the rack 6 to move.

[0032] Furthermore, the transmission assembly 2 8 includes a transmission rod 2 81 rotatably connected to one side of the bottom of the shell 4, and a gear 3 82 meshing with the gear 2 73 is fixedly connected to the rod body of the transmission rod 2 81, and a first bevel gear 83 is fixedly connected to the bottom of the transmission rod 2 81. The rotating gear 2 73 drives the gear 3 82 to rotate, and the set gear 3 82 drives the transmission rod 2 81 to rotate, and the set transmission rod 2 81 drives the first bevel gear 83 to rotate.

[0033] Among them, the number of gears of gear 2 73 is greater than the number of gears of gear 3 82 , which enables gear 2 73 to drive gear 3 82 to accelerate.

[0034] Furthermore, the linkage assembly 9 includes a worm 91 rotatably connected to the side wall of the cabinet 1, and a second bevel gear 92 meshing with the first bevel gear 83 is fixedly connected to the rod body of the worm 91. The rotating first bevel gear 83 drives the second bevel gear 92 to rotate, and the set second bevel gear 92 drives the worm 91 to rotate.

[0035] Furthermore, the threaded assembly 14 includes a threaded rod 141 rotatably connected to the side wall of the cabinet body 1, a worm wheel 142 meshing with the worm 91 is fixedly connected to the rod body of the threaded rod 141, an internal threaded barrel 143 is threadedly connected to the rod body of the threaded rod 141, and the side of the internal threaded barrel 143 away from the cabinet door 2 is fixedly connected to the side wall of the mounting plate 12, the rotating worm 91 drives the worm wheel 142 to rotate, the set worm wheel 142 drives the threaded rod 141 to rotate, and the set internal threaded barrel 143 moves along the thread direction of the threaded rod 141; because the side of the internal threaded barrel 143 away from the cabinet door 2 is fixedly connected to the side wall of the mounting plate 12, and the mounting plate 12 is fixedly connected At the upper part of the inner sleeve 11, this action causes the internal threaded tube 143 to push the inner sleeve 11 toward the main heating device inside the cabinet 1, so that the inner sleeve 11 is close to the main heating device; when the cabinet door 2 is completely closed, the provided cooling fan 17 draws the external airflow into the inner cavity of the cabinet 1, and the external airflow passes through the air inlet duct 16, the outer sleeve 10 and the inner sleeve 11 in turn into the inner cavity of the cabinet 1. Since the outer sleeve 10 is close to the main heating device, this action allows the external airflow to directly act on the main heating device in a direct blowing manner, which allows the inhaled airflow to act well on the main heating device, thereby improving the heat dissipation efficiency of the cooling fan 17 on the main heating device.

[0036] Furthermore, the auxiliary heat dissipation component 19 includes an air collecting hood 191 fixedly mounted on the rear side wall of the inner cavity of the cabinet 1, and a second cooling fan 192 is arranged on the inside of the air collecting hood 191. The two ends of the air collecting hood 191 are symmetrically connected with an air outlet duct 193, and the air outlet duct 193 extends to the side wall surface of the cabinet 1 away from the air collecting hood 191. The cooling fan 2 192 is arranged to operate synchronously with the cooling fan 1 17, and the air flow carrying the heat of the main heating device passes through the air collecting hood 191 and the air outlet duct 193 in turn to be evacuated to the outside of the cabinet 1. Under the action of the cooling fan 2 192, the air collecting hood 191 and the air outlet duct 193, a complete air flow path is formed inside the cabinet 1, and the air flow carrying the heat of the main heating device is quickly evacuated to the outside of the cabinet 1 along the air flow path, which is not easy to cause heat accumulation of the main heating device.

[0037] Working principle: When in use: when the staff closes the cabinet door 2, the side of the sliding rod 51 away from the cabinet door 2 abuts against the baffle 3. As the cabinet door 2 continues to close, the side of the sliding rod 51 away from the cabinet door 2 continues to move toward the inner cavity of the shell 4 under the action of the baffle 3, thereby causing the sliding rod 51 to drive the circular plate 52 to move, and the circular plate 52 drives the rack 6 to move. In this process, the spring 53 is stretched under force; due to the meshing relationship between the rack 6 and the gear 1 72, the rack 6 will drive the gear 1 72 to rotate during the movement, and the gear 1 72 drives the transmission rod 1 71 to rotate, and the transmission rod 1 71 drives the gear 2 73 to rotate. The rotating gear 2 73 drives the gear 3 82 to rotate. The gear 3 82 drives the transmission rod 2 81 to rotate. The transmission rod 2 81 drives the first bevel gear 83 to rotate. The rotating first bevel gear 83 drives the second bevel gear 92 to rotate. The second bevel gear 92 drives the worm 91 to rotate. The rotating worm 91 drives the worm wheel 142 to rotate, and the worm wheel 142 drives the threaded rod 141 to rotate, and the internal threaded barrel 143 moves along the thread direction of the threaded rod 141; because the side of the internal threaded barrel 143 away from the cabinet door 2 is fixedly connected to the side wall of the mounting plate 12, and the mounting plate 12 is fixedly connected to the upper part of the inner sleeve 11, this move causes the internal threaded barrel 143 to push the inner sleeve 11 toward the main heating device inside the cabinet 1, so that the inner sleeve 11 is close to the main Heating device; When the cabinet door 2 is completely closed, the cooling fan 17 is provided to suck the external airflow into the inner cavity of the cabinet 1. The external airflow passes through the air inlet duct 16, the outer sleeve 10 and the inner sleeve 11 in sequence and enters the inner cavity of the cabinet 1. Since the outer sleeve 10 is close to the main heating device, the external airflow directly acts on the main heating device in a direct blowing manner. This makes the inhaled airflow act well on the main heating device, thereby improving the heat dissipation efficiency of the cooling fan 17 on the main heating device;

[0038] In addition, when the cabinet door 2 is opened, the inner sleeve 11 is retracted into the outer sleeve 10 under the elastic force of the spring 53, thereby reducing the space occupied by the inner sleeve 11 and making it easier for subsequent staff to inspect and repair the components inside the cabinet 1;

[0039] In addition, the cooling fan 2 192 is set to operate synchronously with the cooling fan 1 17, and the air flow carrying the heat of the main heating components is evacuated to the outside of the cabinet 1 through the wind collecting hood 191 and the air outlet duct 193 in turn. Under the action of the cooling fan 2 192, the wind collecting hood 191 and the air outlet duct 193, a complete air flow path is formed inside the cabinet 1, and the air flow carrying the heat of the main heating components is quickly evacuated to the outside of the cabinet 1 along the air flow path. This reduces the residence time of heat inside the cabinet 1, and makes it less likely that the heat of the main heating components will accumulate.
