[0022] 3.

Push the two sets of clamping blocks to move in opposite directions, and start squeezing the two sets of first compression springs while sliding in the slide, then place the component body on the waterproof board, and then release the push on the two sets of clamping blocks. When the first compression spring feels that the pressure disappears, it drives the two sets of clamping blocks to limit the component body. During the limiting process, it drives the insulating pad to limit the component body, which improves the casual installation effect of the control component. When a short circuit or other power outage occurs later, the clamping block can be directly pushed to remove the component, avoiding the problem of damage to the component due to power outage, and improving the use effect of the control component.

DETAILED DESCRIPTION

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0035] The embodiment of the present invention provides a motor controller with a temperature sensing component. It includes a control box component 1, for example, Figure 1 As shown, a quick-release assembly 2 is installed on the bottom inner wall of the control box assembly 1, and a constant temperature assembly 3 is clamped on the top, and a protective assembly 4 is installed on the bottom of the constant temperature assembly 3.

[0036] For example, Figure 2 As shown, the control box assembly 1 includes a control box body 101, two groups of snap-in holes 102 are symmetrically opened on the top of the control box body 101, two groups of first flow grooves 103 are symmetrically opened on the inner walls on both sides of the control box body 101, and a second flow groove 104 is opened on the bottom inner wall, the first flow groove 103 is connected to the second flow groove 104, a plurality of groups of threading holes 105 are opened at equal intervals on one side wall of the control box body 101, and two groups of first electromagnetic blocks 106 are symmetrically installed on one side wall, a noise sensor 107 is installed on the inner wall of the control box body 101, and a plurality of groups of water-absorbing pads 108 are symmetrically installed on the bottom inner wall.

[0037] For example, Figure 3 As shown, the quick-release assembly 2 includes an insulating plate 201, the bottom of which is mounted on the bottom inner wall of the control box body 101, a waterproof plate 202 is mounted on the top of the insulating plate 201, a slide 203 is provided on the top of the waterproof plate 202, two groups of fixing blocks 204 are symmetrically mounted on the top edge of the waterproof plate 202, one end of a group of first compression springs 205 is mounted on one side wall of each group of the fixing blocks 204, a group of clamping blocks 206 is mounted on the other end of each group of the first compression springs 205, each group of the clamping blocks 206 is slidably connected in the slide 203, a group of insulating pads 207 is mounted on one side wall of each group of the clamping blocks 206, an element body 208 is provided on the top of the waterproof plate 202, and a temperature sensing structure 209 is mounted on the outer wall of the element body 208.

[0038] The two groups of clamping blocks 206 are pushed to move in opposite directions, and the two groups of first compression springs 205 are squeezed while sliding in the slide 203, and then the component body 208 is placed on the waterproof board 202, and then the push on the two groups of clamping blocks 206 is released. When the first compression spring 205 feels that the pressure disappears, it drives the two groups of clamping blocks 206 to limit the component body 208. During the limiting process, the insulating pad layer 207 is driven to limit the component body 208, thereby improving the casual wearing effect of the control component. When a short circuit or other power outage occurs later, the clamping block 206 can be directly pushed to remove the component, thereby avoiding the problem of power outage damaging the component and improving the protection effect of the control component.

[0039] For example, Figure 4 and Figure 5As shown, the thermostatic component 3 includes a cover plate 301, and two groups of clamping rods 313 are symmetrically installed on the bottom edge of the cover plate 301, and the clamping rods 313 are movably clamped with the clamping holes 102, and one end of two groups of second compression springs 302 are symmetrically installed on the bottom of the cover plate 301, and a limiting plate 303 is connected between the other ends of the two groups of second compression springs 302, and the outer wall of the limiting plate 303 is slidably connected to the inner wall of the control box body 101, and two groups of second electromagnetic blocks 314 are symmetrically installed on the bottom edge of the limiting plate 303, and the first electromagnetic block 106 is magnetically connected to the second electromagnetic block 314, and an electric push rod 304 is installed on the bottom of the cover plate 301, and the output of the electric push rod 304 A push plate 305 is installed on the output end, and two groups of refrigeration box structures 306 are symmetrically installed on the top of the limit plate 303. Each group of the refrigeration box structures 306 is connected to a group of delivery pipes 307, and one end of each group of delivery pipes 307 is connected to a group of extrusion head structures 308. A group of electric ball valves 309 are installed between each group of the refrigeration box structures 306 and the delivery pipes 307. A group of push rods 310 are installed on the outer wall of each group of delivery pipes 307. Two groups of placement tubes 311 are symmetrically installed on the bottom of each group of the cover plates 301. The outer wall of each group of placement tubes 311 is connected to a group of injection tube structures 312, and the input end of each group of injection tube structures 312 is located directly above the push rod 310.

[0040] The temperature is monitored by the temperature sensing structure 209. When the component body 208 becomes uncontrollable and the temperature rises rapidly due to external conditions, the first electromagnetic block 106 and the second electromagnetic block 314 are separated from the magnetic connection state. Then, when the first compression spring 205 senses the disappearance of the pressure, it drives the limit plate 303 to rise. When the limit plate 303 rises, it drives several groups of limit rings 409 to rise. When the limit rings 409 rise, the connection line and the component body 208 are disconnected to avoid secondary damage to the structure caused by the line connection. Then, when the delivery tube 307 rises, it drives the push rod 310 to squeeze the injection tube structure. Structure 312, with the help of the rebound force of the first compression spring 205, drives the injection tube structure 312 to squeeze the sulfur hexafluoride gas in the placement tube 311. The sulfur hexafluoride gas can effectively prevent breakdown in electrical equipment due to its electrical insulation performance and arc extinguishing performance. The sulfur hexafluoride gas enters the second flow groove 104 along the first flow groove 103 with the cold air, and then quickly fills the sealed control box body 101. When the component body 208 produces abnormal noise during use, it can be monitored and protected by the noise sensor 107, thereby improving the structural temperature sensing protection effect while improving the working effect of the motor controller.

[0041] For example, Figure 6 and Figure 7As shown, the protective component 4 includes an electric slide 401, the top of the electric slide 401 is installed on the bottom of the limit plate 303, and the output end of the electric slide 401 is transmission-connected with a transmission plate 402, and a sliding cavity 403 is opened on the bottom of the transmission plate 402, and a plurality of groups of sliding blocks 404 are slidingly connected in the sliding cavity 403, and each group of sliding blocks 404 is rotatably connected to a group of rotating rods 405, and the outer wall of the rotating rods 405 is connected to a connecting plate 406, and a rotating column 407 is installed on the bottom of the connecting plate 406, and a fixed plate 408 is rotatably connected on the outer wall of the rotating column 407, and a limiting ring 409 is installed on the bottom of the fixed plate 408, and an inflatable bag structure 410 is installed on the inner wall of the limiting ring 409, and an air pump 411 is installed on the outer wall of the fixed plate 408, and the output end of the air pump 411 is connected to the input end of the inflatable bag structure 410.

[0042] The connection line of the motor passes through the threading hole 105 and then through the limiting ring 409, and is then electrically connected to the component body 208, and then drives the clamping rod 313 to engage with the clamping hole 102, so that the control box body 101 is a closed space, and then the electric push rod 304 is started to drive the push plate 305 to descend. When the push plate 305 descends, it drives the limiting plate 303 to slide and descend on the inner wall of the control box body 101, and then starts to pull the second compression spring 302. When the limiting plate 303 descends to the specified position, it drives the second electromagnetic block 314 to be magnetically connected with the first electromagnetic block 106. At this time, the two sets of extruder head structures 30 The output end of 8 is in the output state inside the first flow groove 103, and the electric ball valve 309 is opened, so that the cold air of the refrigeration box structure 306 enters the first flow groove 103 through the delivery pipe 307, and then enters the second flow groove 104 from the first flow groove 103, gathering the cold air in a specific area, improving the cold air utilization effect while improving the cooling effect of the structure. At this time, a water-absorbing pad layer 108 is provided on the inner wall of the bottom of the control box body 101, and the moisture generated will enter the water-absorbing pad layer 108 and will not cause damage to the component body 208, thereby improving the cold air utilization effect while improving the protection effect of the structure.

[0043] Start the air pump 411 to fill the inflatable bag structure 410, so that the inflatable bag structure 410 expands and wraps the connecting line to limit the position. In the subsequent use process, it will automatically drive the sliding block 404 to slide in the sliding cavity 403 according to the shaking, and at the same time drive the rotating column 407 to rotate by itself. In order to prevent the line from falling off, it will naturally drive the rotating rod 405 to rotate the angle to relieve the pain, breaking away from the commonly used power structure limit drive, and using the most flexible limit structure to wrap and protect the line, thereby improving the dispersed wrapping effect of the line.

[0044] Temperature monitoring is performed through the temperature sensing structure 209, and the limit ring 409 rises to disconnect the connecting line from the component body 208, thereby avoiding secondary damage to the structure caused by the line connection. The rebound force of the first compression spring 205 drives the injection tube structure 312 to squeeze the sulfur hexafluoride gas in the placement tube 311, so that the sulfur hexafluoride gas with electrical insulation and arc extinguishing properties is quickly filled in the sealed control box body 101. When the component body 208 produces abnormal noise during use, it is monitored and protected by the noise sensor 107, thereby improving the structural temperature sensing protection effect and the working effect of the motor controller.

[0045] Start the air pump 411 to fill the inflatable bag structure 410, so that the inflatable bag structure 410 expands and wraps the connecting line to limit the position. In the subsequent use process, it will automatically drive the sliding block 404 to slide in the sliding cavity 403 according to the shaking, and at the same time drive the rotating column 407 to rotate by itself. In order to prevent the line from falling off, it will naturally drive the rotating rod 405 to rotate the angle to relieve the pain, breaking away from the commonly used power structure limit drive, and using the most flexible limit structure to wrap and protect the line, thereby improving the dispersed wrapping effect of the line.

[0046] Open the electric ball valve 309, so that the cold air of the refrigeration box structure 306 enters the first flow groove 103 through the delivery pipe 307, and then enters the second flow groove 104 from the first flow groove 103, gathering the cold air in a specific area, thereby improving the cold air utilization effect while improving the cooling effect of the structure. At this time, a water-absorbing pad layer 108 is provided on the inner wall of the bottom of the control box body 101. The moisture generated will enter the water-absorbing pad layer 108 and will not cause damage to the component body 208, thereby improving the cold air utilization effect while improving the protection effect of the structure.

[0047] Push the two groups of clamping blocks 206 to move in opposite directions, and start squeezing the two groups of first compression springs 205 while sliding in the slide 203, then place the component body 208 on the waterproof board 202, and then release the push on the two groups of clamping blocks 206. When the first compression spring 205 feels that the pressure disappears, it drives the two groups of clamping blocks 206 to limit the component body 208. During the limiting process, it drives the insulating pad 207 to limit the component body 208, thereby improving the casual wearing effect of the control component. When a short circuit or other power outage occurs later, the clamping block 206 can be directly pushed to remove the component, avoiding the problem of power outage damaging the component and improving the use effect of the control component.
