[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a pressure sensor signal acquisition device, comprising: an acquisition device body 1, a protective component 2 is fixedly connected to the right surface of the acquisition device body 1, and a heat dissipation component 3 is fixedly connected to the bottom of the acquisition device body 1; the protective component 2 comprises two rectangular blocks 205, a bidirectional screw rod 206 is movably penetrated at the bottom of one of the rectangular blocks 205, a clamping block 201 is symmetrically threadedly connected to the outer surface of the bidirectional screw rod 206, a rubber pad 202 is fixedly connected to the adjacent sides of the outer surfaces of the two clamping blocks 201, a guide rod 203 is movably penetrated between the outer surfaces of the two clamping blocks 201, both ends of the guide rod 203 are fixedly connected to the fixed block 204, the top of the bidirectional screw rod 206 is rotatably connected to the bottom of the other rectangular block 205, and the bottom of the bidirectional screw rod 206 is fixedly connected to the handle 207. The left surfaces of the two rectangular blocks 205 are fixedly connected to the right surface of the acquisition device body 1, and the left surfaces of the two fixed blocks 204 are fixedly connected to the right surface of the acquisition device body 1.

[0023] The effect achieved by the entire embodiment 1 is that after the output end of the external pressure sensor is plugged into the access end on the right side of the acquisition device body 1, the handle 207 can be turned to make the bidirectional screw rod 206 rotate on the two rectangular blocks 205, so that the two clamping blocks 201 are driven to move synchronously relative to each other through the rotation of the bidirectional screw rod 206, and the movement of the clamping blocks 201 is more stable with the cooperation of the guide rod 203 and the fixed block 204, so that the input end of the pressure sensor is clamped and fixed by the two clamping blocks 201, and the clamping effect of the clamping blocks 201 on the input end can be increased with the cooperation of the two rubber pads 202, so as to avoid the phenomenon that the input end and the access end of the acquisition device body 1 become loose due to external pulling, thereby ensuring the stability of the connection, and then The signal conditioning circuit on the acquisition device body 1 amplifies the weak signal output by the pressure sensor, filters out noise, and performs necessary signal conversion. The data acquisition module converts the conditioned analog signal into a digital signal. The data processing unit processes the collected digital signal, extracts effective information, and stores it in the built-in memory. The processed data is transmitted to an external display device or computer through the wireless communication module for real-time display and further analysis. When the acquisition device body 1 is not in use, the handle 207 can be rotated to drive the clamping block 201 to move, so that the two rubber pads 202 are fitted together, so that the access end of the acquisition device body 1 can be blocked by the two clamping blocks 201 to reduce the entry of external dust and avoid subsequent poor contact.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, the heat dissipation assembly 3 includes a base 301, a plurality of dampers 304 are evenly fixedly connected to the top of the base 301, the outer surfaces of the plurality of dampers 304 are sleeved with springs 302, the top of the base 301 near the four corners are fixedly connected to support rods 303, a top plate 305 is fixedly connected between the tops of the plurality of support rods 303, a protective net 306 is fixedly connected to the top of the top plate 305, a support frame 308 is fixedly connected to the inner surface of the top plate 305, a fan 307 is fixedly connected to the bottom of the support frame 308, the position of the fan 307 matches the position of the protective net 306, and the tops of the plurality of dampers 304 are fixedly connected to the bottom of the collection device body 1.

[0025] The effect achieved by the entire embodiment 2 is that the collection device body 1 is placed by the base 301, so that when the collection device body 1 is in use, through the cooperation of the damper 304 and the spring 302, when external vibration is transmitted to the collection device body 1, the spring 302 will first absorb the vibration energy and deform, and then convert part of the energy into heat energy or other forms of energy dissipation through the damper 304, effectively reducing the impact of external vibration on the collection device body 1 and protecting internal precision components. At the same time, a certain degree of protection can be provided by the support rod 303 and the top plate 305, and during use, the fan 307 can be started and the auxiliary protection net 306 can be used to increase the air flow outside the collection device body 1, dissipate heat for the collection device body 1, and ensure the stability of the collection device body 1 when in use.

[0026] Working principle: After plugging the output end of the external pressure sensor with the access end on the right side of the acquisition device body 1, the handle 207 can be turned to make the bidirectional screw rod 206 rotate on the two rectangular blocks 205, so that the two clamping blocks 201 are driven to move relative to each other synchronously through the rotation of the bidirectional screw rod 206, and the movement of the clamping blocks 201 is more stable with the cooperation of the guide rod 203 and the fixed block 204, so that the input end of the pressure sensor is clamped and fixed by the two clamping blocks 201, and the clamping effect of the clamping blocks 201 on the input end can be increased with the cooperation of the two rubber pads 202, so as to avoid the phenomenon that the input end and the access end of the acquisition device body 1 become loose due to external force, thereby ensuring the stability of the connection, and then the pressure sensor data is collected through the acquisition device body 1.

[0027] During use, with the cooperation of the damper 304 and the spring 302, when external vibration is transmitted to the collection device body 1, the spring 302 will first absorb the vibration energy and deform, and then convert part of the energy into heat or other forms of energy through the damper 304, effectively reducing the impact of external vibration on the collection device body 1 and protecting the internal precision components. At the same time, a certain degree of protection can be provided through the support rod 303 and the top plate 305. During use, the fan 307 can be started and the auxiliary protection net 306 can be used to increase the air flow outside the collection device body 1, dissipate heat for the collection device body 1, and ensure the stability of the collection device body 1 during use. When the collection device body 1 is not in use, the handle 207 can be rotated to drive the clamping block 201 to move, so that the two rubber pads 202 are fitted together, so that the access end of the collection device body 1 can be blocked by the two clamping blocks 201, reducing the entry of external dust and avoiding subsequent poor contact.

[0028] The wiring diagram of the collection device body 1 in the present invention belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the collection device body 1 are not explained in detail.
