Abstract

[0002] Proportional valve cards are mainly used for closed-loop control of nuclear power high-pressure regulating valves. They are dedicated key components of nuclear power steam turbine control systems. The function of proportional valve cards is that the control device must be able to control valves with two-stage valve core feedback, namely the main stage and the pilot stage. PWM (pulse width modulation wave) is used for drive control to achieve fully digital integrated circuit design and Ethernet data communication.
[0003] At present, the data collection of proportional valve cards requires the use of portable industrial computers, which have the advantages of small size, light weight, easy installation, simple operation and maintenance. At the same time, the program can be debugged through the industrial computer, but the industrial computer generally adopts two installation methods: embedded and wall-mounted. After the industrial computer is installed, it will not move for a long time, resulting in a lot of dust accumulation on the top of the industrial computer. At the same time, the gap between the heat sink on the top of the industrial computer is small, making it difficult for the staff to clean. When the dust accumulates too much, it will greatly affect the heat dissipation efficiency of the heat sink. Summary of the invention

[0021] The present application is further described in detail below with reference to the accompanying drawings and embodiments.
[0022] like Figure 1As shown, the present application provides a portable proportional valve card industrial computer, comprising: an industrial computer body 1, mounting ears 2, a docking port 3, a heat sink 4, and a fixing block 5; the mounting ears 2 are connected to both sides of the bottom end of the industrial computer body 1, the docking port 3 is connected to the front end of the industrial computer body 1, the heat sink 4 is connected to the top of the industrial computer body 1, and fixing blocks 5 are installed on the top of the industrial computer body 1 and on both sides of the heat sink 4, a cleaning component is arranged between the two fixing blocks 5, and a fixing component is arranged inside the fixing block 5.
[0023] like Figure 1-3 As shown, the cleaning assembly includes a cross bar 6, a cleaning brush 7, a chute 9 and a slider 10. The cross bar 6 is horizontally arranged between the fixed blocks 5, the cleaning brush 7 is installed at the bottom end of the cross bar 6, the chute 9 is opened inside the fixed block 5, the slider 10 is adapted to the chute 9, and is slidably connected inside the chute 9. The two ends of the cross bar 6 are respectively connected to the outer side walls of the slider 10, and the cross bar 6 is slidably connected to the chute 9 through the slider 10. Through the use of the cleaning assembly, the cleaning assembly cleans the dust between the top of the industrial computer body 1 and the gap between the heat sink 4, thereby achieving the purpose of facilitating dust cleaning and reducing the impact of dust on heat dissipation efficiency.
[0024] like Figure 1-3 As shown, the screw 8 is threadedly connected to the top of the cross bar 6, and the cleaning brush 7 is fixedly connected to the cross bar 6 through the screw 8, and is detachably connected to the cross bar 6 through the screw 8. The fixed and detachable connection between the cleaning brush 7 and the cross bar 6 is formed by the screw 8, so that the cleaning brush 7 can be removed and reinstalled through the screw 8 after being worn, thereby avoiding the situation where the cleaning brush 7 is damaged and the cleaning effect is reduced.
[0025] like Figure 1-3 As shown, the slider 10 is T-shaped, and a sliding connection is formed between the cross bar 6 and the slider 10 and the slide groove 9, so that the cross bar 6 moves smoothly along the slide groove 9 with the slider 10. At the same time, the slider 10 is T-shaped to prevent the slider 10 from sliding away from the slide groove 9.
[0026] like Figure 1 , 3 As shown in Figure 4, the fixing assembly includes a spring piece 11, a limiting block 12 and a limiting groove 13. The spring piece 11 is installed inside the fixing block 5, the limiting block 12 is connected to one end of the spring piece 11, and the limiting groove 13 is opened on the side wall of the slider 10. The limiting block 12 is adapted to the limiting groove 13. By using the fixing assembly, the cleaning brush 7 is fixed by the fixing assembly after use to avoid automatic sliding.
[0027] like Figure 1 , 3As shown in FIG. 4 , the spring piece 11 is installed in an inclined shape inside the fixed block 5 . The spring piece 11 is made of flexible metal. Through the use of the spring piece 11 , the limit block 12 is quickly clamped in the limit groove 13 through the elastic force of the spring piece 11 , while not affecting the sliding of the slider 10 .
[0028] like Figure 1 , 3 As shown in Figures 4, the limit block 12 is elastically connected to the slider 10 through the spring sheet 11, and the limit block 12, the spring sheet 11 and the slider 10 are elastically connected, so that the limit block 12 can be quickly clamped in the limit groove 13 to fix the slider 10 through the elasticity of the spring sheet 11.
[0029] Specific working principle: Figure 1-4 As shown, when using the portable proportional valve card industrial computer, first, the proportional valve card is connected to the industrial computer body 1 through the Ethernet communication connection mode, and the docking end of the proportional valve card is docked with the docking interface 3 at the front end of the industrial computer body 1 through the network cable. Then the industrial computer body 1 collects data from the proportional valve card, and at the same time, the program can be debugged through the industrial computer body 1. Then, the industrial computer body 1 is fixed through the mounting ears 2 on both sides. Then, after dust accumulates on the top of the industrial computer body 1, the cross bar 6 is pushed forward and backward to allow the cleaning brush 7 to remove the dust accumulated between the top of the industrial computer body 1 and the gap between the heat sink 4. At this time, the cross bar 6 drives the slider 10 to slide along the slide groove 9, and then the slider 1 0 The limiting groove 13 on the side wall squeezes the limiting block 12, and then the limiting block 12 is squeezed to drive the spring piece 11 to shrink and deform. At this time, the limiting block 12 moves out of the limiting groove 13, and then the cleaning brush 7 connected to the bottom end of the cross bar 6 removes the dust accumulated between the top of the industrial computer body 1 and the gap between the heat sink 4, so that the dust will not affect the heat dissipation, so as to facilitate the cleaning of dust and reduce the impact of dust on the heat dissipation efficiency. At the same time, after the cleaning brush 7 is worn out after long-term use, the screw 8 is rotated to release the fixation between the cleaning brush 7, so as to replace the new cleaning brush 7 for installation, thereby avoiding the situation where the cleaning brush 7 is damaged and the cleaning effect is reduced. This is the characteristic of the portable proportional valve card industrial computer.
[0030] The present application is described in detail above in conjunction with the accompanying drawings and embodiments, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of ordinary technicians in the field without departing from the purpose of the present application. Any content not described in detail in the present application can adopt the existing technology.
