[0020] As Figures 1-6 shown, the present invention discloses a technical solution: a DC simulator capable of assisting heat dissipation, including a DC simulator body 1, heat dissipation holes 2 are opened on the front surface of the DC simulator body 1, an operating table 3 is fixed on the front surface of the DC simulator body 1, a lifting handle 4 is fixed on the side wall of the DC simulator body 1, a protective shell 5 slides on the outer wall of the DC simulator body 1, the protective shell 5 is provided with a moving device 6 for conveniently carrying and moving the DC simulator body 1, the moving device 6 is provided with a protective device 7 for protecting the front surface of the DC simulator body 1, the protective shell 5 is provided with a heat dissipation device 8 for assisting heat dissipation, and the protective shell 5 is provided with a cleaning device 9 for conveniently cleaning the heat dissipation holes 2.
[0021] The above-mentioned mobile device 6 includes a support base 61, a first rotating shaft 62, a rotating handle 63, a first bevel gear 64, a fixing plate 65, a second bevel gear 66, a threaded rod 67, a bottom plate 68 and a universal wheel 69. The support base 61 is fixedly installed on the bottom surface of the protective shell 5. The first rotating shaft 62 penetrates through the support base 61 and is rotatably connected at the penetration point. The rotating handle 63 is fixedly installed at the right end of the first rotating shaft 62. When it is necessary to move the DC simulator, the operator can manually rotate the rotating handle 63. When the rotating handle 63 rotates under force, it will drive the connected first rotating shaft 62 to rotate accordingly. A first bevel gear 64 is fixed to the left end of the first rotating shaft 62. The rotation of the first rotating shaft 62 will drive the first bevel gear 64 installed on it to start rotating. A fixing plate 65 is fixed inside the support base 61. A cylinder protrudes from the upper surface of the fixing plate 65. The cylinder penetrates through the second bevel gear 66 and is rotatably connected at the penetration point. The first bevel gear 64 and the second bevel gear 66 are meshed. The rotation of the first bevel gear 64 will drive the second bevel gear 66 to rotate accordingly. A threaded rod 67 is fixed to the upper surface of the second bevel gear 66. The rotation of the second bevel gear 66 will drive the connected threaded rod 67 to rotate. The threaded rod 67 penetrates through the bottom plate 68 and is threadedly connected at the penetration point. The heat conduction plate 81 above the bottom plate 68 will be restricted so that it can only slide up and down. The heat conduction plate 81 plays a guiding role for the bottom plate 68 in this process. Therefore, when the threaded rod 67 rotates, it drives the bottom plate 68 to move up and down along a predetermined direction. The universal wheel 69 is fixed to the bottom surface of the bottom plate 68. The up and down movement of the bottom plate 68 will drive the universal wheel 69 installed below it to move down together. The mobile device 6 can drive the bottom plate 68 to gradually rise or fall by manually rotating the rotating handle 63, changing the support method at the bottom of the DC simulator, making it more convenient to move the DC simulator or providing stable support during use, ensuring that during subsequent use of the DC simulator to carry out related work or operations, it will not move easily due to some slight external forces and other situations, providing great convenience for the position transfer of the equipment while ensuring the stability and safety during use.
[0022] The above-mentioned protection device 7 includes a protective cover 71, a limit post 72 and a hinge rod 73. The bottom end of the protective cover 71 is hinged to the bottom surface of the protective shell 5. The side wall of the bottom plate 68 is fixed with a limit post 72. When the bottom plate 68 moves up and down, the connected limit post 72 will move up and down synchronously under the driving of the bottom plate 68. The limit post 72 penetrates through the hinge rod 73 and is rotatably connected at the penetration point. During the movement of the limit post 72, it will drive the hinge rod 73 rotatably connected to it to move up and down. A cylinder protrudes from the side wall of the hinge rod 73, and the cylinder slides in the groove on the side wall of the protective cover 71. Also, because the side walls of the hinge rod 73 and the protective cover 71 are assembled in a sliding connection manner, this end of the hinge rod 73 can only move on the specific sliding route set by the protective cover 71 and cannot change the trajectory at will. With the up and down movement of the hinge rod 73 and the sliding along the established route, it will exert a corresponding force on the protective cover 71, thereby driving the protective cover 71 to start rotating up or down around its specific rotation point. The protection device 7 can raise the protective cover 71 synchronously with the movement of the DC simulator, effectively protecting the DC simulator, preventing some external dust, debris or other factors that may damage it from affecting the normal state of the DC simulator, and lowering the protective cover 71 synchronously and fixedly with the DC simulator, which is convenient for the operator to perform various operations and normal use of the DC simulator during use, ensuring the convenience and efficiency of the use process.
[0023] The above-mentioned heat dissipation device 8 includes a heat conduction plate 81, a cooling pipe 82, a one-way valve pump 83, a heat conduction fin 84, an energy conversion device 85, a support rod 86, an AC motor 87, a second rotating shaft 88 and a fan blade 89. The heat conduction plate 81 is fixedly installed on the upper surface of the bottom plate 68. The heat conduction plate 81 penetrates through the bottom surface of the protective shell 5, and the penetration part is slidably connected. The inner wall of the protective shell 5 is fixed with a cooling pipe 82. The cooling pipe 82 can help the DC simulator body 1 to dissipate heat effectively under the premise of the heat conduction plate 81 conducting heat. There is a coolant flowing in the cooling pipe 82. The outer wall of the protective shell 5 is fixed with a one-way valve pump 83. The one-way valve pump 83 is communicated with the cooling pipe 82. Under the action of the one-way valve pump 83, the coolant in the cooling pipe 82 will always remain in a flowing state. In this process, the coolant will continuously absorb the heat emitted by the DC simulator body 1 and carry this heat to circulate along the cooling pipe 82. The upper surface of the one-way valve pump 83 is fixed with a heat conduction fin 84. The heat conduction fin 84 installed above the one-way valve pump 83 will receive the heat carried out by the coolant. The outer wall of the protective shell 5 is fixed with an energy conversion device 85. The bottom surface of the energy conversion device 85 is fixedly connected to the heat conduction fin 84. The heat conduction fin 84 transfers this heat into the connected energy conversion device 85. The energy conversion device 85 can convert the received thermal energy into electrical energy. The upper surface of the energy conversion device 85 is fixed with a support rod 86. The inner wall of the support rod 86 is fixed with an electric wire. One end of the support rod 86 far away from the energy conversion device 85 is fixed with an AC motor 87. The converted electrical energy will be conducted along the electric wire pre-laid inside the support rod 86 and finally transferred into the AC motor 87. The output end of the AC motor 87 is fixed with a second rotating shaft 88. After receiving the electrical energy, the AC motor 87 will immediately start to operate, driving the connected second rotating shaft 88 to rotate. The outer wall of the second rotating shaft 88 is fixed with a fan blade 89. The rotation of the second rotating shaft 88 will further drive the fan blade 89 installed on its outer wall to start rotating. The fan blade 89 will accelerate the flow rate of the surrounding air, enabling the hot air to be taken away faster and the cold air to be supplemented more quickly. This heat dissipation device 8 can greatly enhance the overall heat dissipation effect, ensure that the DC simulator body 1 can operate stably in a suitable temperature environment, and the existence of the energy conversion device 85 can save more electrical energy and reduce energy consumption.
[0024] The above cleaning device 9 includes a spur gear 91, a guide plate 92, a saw blade 93 and a cleaning sponge 94. A second rotating shaft 88 passes through the spur gear 91 and is fixedly connected at the passing-through part. The rotation of the second rotating shaft 88 will drive the spur gear 91 to rotate together. The guide plate 92 is fixed on the upper surface of the protective shell 5. The guide plate 92 passes through the saw blade 93 and is slidably connected at the passing-through part. The saw blade 93 is restricted by the guide plate 92, so that the saw blade 93 can only slide left and right along the direction defined by the guide plate 92. The saw blade 93 meshes with the spur gear 91. During the rotation of the spur gear 91, it will drive the saw blade 93 to move. The cleaning sponge 94 is fixed to the bottom surface of the saw blade 93. As the saw blade 93 slides left and right, the cleaning sponge 94 fixedly connected to the saw blade 93 will also move left and right together. The cleaning sponge 94 is soft in texture and has good adsorption and cleaning capabilities. During the left and right movement, it will continuously contact the surface of the heat dissipation holes 2, adsorb or wipe off all the dust, debris, etc. accumulated around and inside the heat dissipation holes 2. The cleaning device 9 can effectively clean the heat dissipation holes 2 comprehensively and meticulously, ensuring that the heat dissipation holes 2 are always unobstructed, so as to better play its heat dissipation function and maintain the overall good heat dissipation performance of the DC simulator.
[0025] Working principle: When it is necessary to move the DC simulator, the operator can manually rotate the rotating handle 63. When the rotating handle 63 is forced to rotate, it will drive the connected first rotating shaft 62 to rotate accordingly. The rotation of the first rotating shaft 62 will further drive the first bevel gear 64 mounted on it to start rotating. Since the first bevel gear 64 and the second bevel gear 66 are in a meshing structural relationship, the rotation of the first bevel gear 64 will drive the second bevel gear 66 to rotate. The rotation of the second bevel gear 66 will drive the threaded rod 67 connected to it to rotate. At this time, the heat conduction plate 81 above the bottom plate 68 will be restricted, so that it can only slide up and down. The heat conduction plate 81 plays a guiding role for the bottom plate 68 in this process. Therefore, when the threaded rod 67 rotates, it drives the bottom plate 68 to move up and down along the established direction. The up and down movement of the bottom plate 68 will drive the universal wheels 69 mounted below it to move downward together until the universal wheels 69 contact the ground. Then, the universal wheels 69 effectively support the DC simulator, enabling the DC simulator to be easily moved. When the DC simulator is moved to the designated position and the moving operation is completed and it needs to be used normally, the operator can also manually rotate the rotating handle 63 and drive the bottom plate 68 to gradually rise in the reverse transmission sequence described above. As the bottom plate 68 rises, the universal wheels 69 will slowly leave the ground. Eventually, the DC simulator is stably supported by the originally designed support seat 61, ensuring that during the subsequent use of the DC simulator to carry out related work or operations, it will not move easily due to some slight external forces or other situations.
[0026] When the bottom plate 68 starts to move downward, the associated limit post 72 will move downward synchronously under the driving action of the bottom plate 68. During the movement of the limit post 72, it will drive the hinged rod 73 rotatably connected thereto to move downward as well. The hinged rod 73 has a special connection structure, and the other end thereof is assembled with the side wall of the protective cover 71 in a sliding connection manner. Therefore, this end of the hinged rod 73 can only move on the specific sliding route set by the protective cover 71 and cannot change the trajectory arbitrarily. With the downward movement of the hinged rod 73 and the sliding along the established route, it will exert a corresponding force on the protective cover 71, thereby driving the protective cover 71 to start rotating and rising around its specific rotation point. After the protective cover 71 rises, it can well cover the front of the DC simulator and play an effective protective role for the DC simulator. On the contrary, when the bottom plate 68 moves upward, under the linkage of the corresponding connection structure, it will also drive the protective cover 71 to rotate and lower in the opposite direction, so that the DC simulator is no longer blocked by the protective cover 71, facilitating the operator to perform various operations and normal use on the DC simulator.
[0027] On the inner wall of the protective shell 5, a cooling pipe 82 is laid. Its original design intention was to help the DC simulator body 1 dissipate heat effectively. However, the DC simulator body 1 has a unique outer shape structure, with its lower half being relatively narrow. As a result, it cannot directly contact the cooling pipe 82. In the actual heat dissipation process, this situation greatly reduces the heat dissipation effect of the lower half of the DC simulator body 1 and fails to achieve an ideal heat dissipation state. However, when the bottom plate 68 starts to move upward under relevant operations, the heat conduction plate 81 closely connected to it will also rise synchronously with the bottom plate 68. After rising to a certain position, it can contact both the lower half of the DC simulator body 1 and the cooling pipe 82 at the same time, enabling the heat of the DC simulator body 1 to be conducted to the cooling pipe 82, thus greatly enhancing the overall heat dissipation effect. At the same time, the coolant in the cooling pipe 82 will always remain in a flowing state under the action of the one-way valve pump 83. During this process, the coolant will continuously absorb the heat emitted by the DC simulator body 1 and carry this heat along the cooling pipe 82 in a cycle. The heat conduction fin 84 installed above the one-way valve pump 83 will receive the heat carried out by the coolant and then transfer this heat to the energy conversion device 85 connected to it. The energy conversion device 85 can convert the received thermal energy into electrical energy. The converted electrical energy will be conducted along the wires pre-laid inside the support rod 86 and finally transferred to the AC motor 87. When the AC motor 87 receives this electrical energy, it will immediately start to operate, driving the second rotating shaft 88 connected to it to rotate. The rotation of the second rotating shaft 88 will further drive the fan blade 89 installed on its outer wall to start rotating. The fan blade 89 will accelerate the flow rate of the surrounding air, allowing the hot air to be taken away faster and the cold air to be supplemented more quickly.
[0028] When the second rotating shaft 88 starts to rotate, due to its close connection with the spur gear 91, the rotation of the second rotating shaft 88 will directly drive the spur gear 91 to rotate together. During the rotation of the spur gear 91, it will transmit the power of this rotation through the corresponding meshing components, thereby driving the saw blade 93 to start moving. The saw blade 93 is restricted by the guide plate 92, so that the saw blade 93 can only slide left and right along the direction defined by the guide plate 92. As the saw blade 93 slides left and right, the cleaning sponge 94 fixedly connected to the saw blade 93 will also move left and right together. The cleaning sponge 94 is soft in texture and has good adsorption and cleaning capabilities. During the left and right movement, it will continuously contact the surface of the heat dissipation holes 2, adsorbing or wiping off all the dust, debris, etc. accumulated around and inside the heat dissipation holes 2.
[0029] The above has generally described the disclosure of the present invention in detail. However, based on the disclosure of the present invention, some modifications or improvements can be made thereto, which are obvious to those of ordinary skill in the art. Therefore, any modifications or improvements made without departing from the spirit and idea of the disclosure of the present invention are within the scope of protection of the disclosure of the present invention.
