An accommodating arc groove 14 is provided at the upper end of each pressure plate 10 and between the two magnets 16. An extrusion arc groove 13 is provided at the lower end of each pressure plate 10 and between the two magnets 16. The extrusion arc groove 13 and the accommodating arc groove 14 are connected. The inner side of the extrusion arc groove 13 is respectively in contact with the mechanical joint 6 and the sealing soft ring 8, and the inner side of the accommodating arc groove 14 is in contact with the detection probe 7.

[0030] The pressure detection device provided by the present invention is designed with an overall structural coordination so that when the detection probe 7 passes through the mechanical joint 6 and extends to the inner side of the pipe body 2, the sealing soft ring 8 is fitted with the mechanical joint 6, and the two closed pressure plates 10 are used to facilitate the extrusion and limiting of the sealing soft ring 8, thereby achieving a sealing effect at the connection, effectively avoiding leakage and ensuring detection accuracy.

[0031] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0033] Example 1:

[0034] Please refer to Figure 1-5 A pressure detection device includes two pipeline supports 1, a pipeline body 2 is fixed at the upper end of the two pipeline supports 1, a detection support 3 is fixed on the outside of the pipeline body 2 and located between the two pipeline supports 1, a pressure sensor body 5 is provided at the upper end of the inner side of the detection support 3, and a detection probe 7 is provided at the lower end of the pressure sensor body 5 to connect the pressure sensor body 5 with the pipeline body 2 to facilitate pressure detection.

The lower end of the detection probe 7 passes through the mechanical joint 6 and extends to the inner side of the pipeline body 2;

[0035] In order to seal the connection between the pressure sensor body 5 and the pipeline body 2, a sealing soft ring 8 is provided on the outer side of the detection probe 7 and at the upper end of the mechanical joint 6. In order to squeeze the sealing soft ring 8 to limit it and ensure the sealing effect, a pressure plate 10 is symmetrically provided on the inner side of the detection bracket 3 and on the outer side of the sealing soft ring 8. An accommodating arc groove 14 is provided at the upper end of each pressure plate 10 and between the two magnets 16.

[0036] Furthermore, when the two pressing plates 10 are attached to each other, the mechanical joint 6, the detection probe 7 and the sealing soft ring 8 are all attached and limited between the two pressing plates 10, which facilitates the compression of the mechanical joint 6, the detection probe 7 and the sealing soft ring 8 to achieve a sealing effect.

[0038] In order to facilitate flipping open or closing of the pressure plate 10, a hinge 11 is provided between the upper end of each pressure plate 10 away from the sealing soft ring 8 and the detection bracket 3. When the two pressure plates 10 are flipped open by the hinge 11, the magnet 16 and the detection bracket 3 are attached to facilitate adsorption of the pressure plate 10 and the detection bracket 3, thereby achieving fixation of the pressure plate 10;

[0039] When the two pressure plates 10 are opened, it is convenient to inspect the connection. When the two pressure plates 10 are closed and fit together, in order to further press the two pressure plates 10, so as to facilitate the interception of the impact force generated by the crushing of the connection, through grooves 9 are provided inside the two sides of the detection bracket 3 and at the upper ends of the pressure plates 10. Limiting columns 17 are symmetrically provided on the inside of each through groove 9. The limiting columns 17 are fixed to the detection bracket 3.

The lower ends of the two L-shaped pressing frames 18 are fit with the pressure plates 10.

[0043] The use process of the pressure detection device provided by the present invention is as follows: after the detection probe 7 is extended to the inner side of the pipe body 2 through the mechanical joint 6, the connection between the pressure sensor body 5 and the pipe body 2 is completed to facilitate pressure detection of the pipe body 2. At this time, the two pressure plates 10 are flipped and closed by the hinge 11, and the extrusion arc groove 13 and the receiving arc groove 14 are used to facilitate the limited compression of the mechanical joint 6, the detection probe 7 and the sealing soft ring 8, thereby improving the sealing effect. The arrangement of the magnet 16 makes it difficult for the two pressure plates 10 to separate;

[0044] In order to further improve the impact resistance of the two pressure plates 10, the reduction motor 23 is started to drive the second flat gear 24 to rotate, and the bidirectional screw 21 is driven to rotate through the engagement of the second flat gear 24 and the first flat gear 22, thereby driving the two L-shaped pressure frames 18 to approach each other through the guidance of the guide column 20 and the limit column 17, and pressing the two pressure plates 10, so that the impact force can be easily blocked by the two pressure plates 10.
