DETAILED DESCRIPTION

[0040] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution 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.

[0041] like Figure 1 - Fig.12 As shown, in some embodiments of the present invention, a pressure vessel pressure detection device is provided, comprising a pressure sensor 1, the pressure sensor 1 is used to detect the pressure value inside the pressure vessel, so that the device can complete the pressure detection of the pressure vessel, and also includes:

[0042] The exhaust pipe 2 is provided with a shielding plate 3, and the exhaust pipe 2 is used to be inserted into the pressure vessel, and the shielding plate 3 is used to shield the opening of the pressure vessel. When in use, the pressure vessel is first opened, and then the exhaust pipe 2 is inserted into the pressure vessel, and the opening of the pressure vessel is shielded by the shielding plate 3, so that the interior of the pressure vessel is in a sealed state, and high-pressure gas is discharged into the pressure vessel through the exhaust pipe 2 by an air pump or other means, so that the pressure inside the pressure vessel increases;

[0043] The fixing member 4 is installed on the shielding plate 3. The fixing member 4 includes a clamping plate 401 rotatably installed on the shielding plate 3. The clamping plate 401 is used to clamp with the pressure vessel so that the tendency of the shielding plate 3 to move away from the pressure vessel is limited. When in use, the opening of the pressure vessel is mostly connected by a flange, and a drop is formed between the flange and the opening neck of the pressure vessel. After the shielding plate 3 is connected to the pressure vessel, the clamping plate 401 is rotated, and the clamping plate 401 conflicts with the above-mentioned drop. When the pressure on the inner wall of the pressure vessel increases, the shielding plate 3 tends to move away from the pressure vessel, and then the clamping plate 401 conflicts with the above-mentioned drop, further reducing the gap between the two, and preliminarily limiting the rotation of the clamping plate 401 through the conflict, thereby increasing the stability of the device when in use;

[0044] The detection member 5 is installed on the exhaust pipe 2. The detection member 5 includes a detection plate 501. The pressure sensor 1 is installed on the detection plate 501. The detection plate 501 is slidably connected to the exhaust pipe 2. The detection member 5 also includes a slide bar 502 slidably installed on the shielding plate 3. The slide bar 502 is connected to the detection plate 501. When the slide bar 502 slides, the detection plate 501 is driven to slide on the exhaust pipe 2 along the axial direction of the exhaust pipe 2. When the exhaust pipe 2 is inserted into the pressure vessel, the pressure sensor 1 is inserted into the pressure vessel together with the detection plate 501, and the pressure inside the pressure vessel is detected. By sliding the slide bar 502, the detection plate 501 slides in the pressure vessel, and the pressure of different depths in the pressure vessel can be detected, thereby increasing the accuracy of the detection;

[0045] A rubber sealing ring is installed at the sliding connection between the shielding plate 3 and the sliding rod 502 to reduce the possibility of gas leakage into the pressure vessel during use, thereby increasing the feasibility of the device;

[0046] Compared with the prior art, the exhaust pipe 2 is inserted into the pressure vessel, and then the detection plate 501 and the pressure sensor 1 located thereon are brought into the pressure vessel, and the tendency of the baffle plate 3 to move away from the pressure vessel is restricted by the clamping plate 401, so that the baffle plate 3 can block the opening of the pressure vessel to keep the interior sealed, and the exhaust pipe 2 is used to exhaust and pressurize the pressure vessel, and the pressure sensor 1 on the detection plate 501 is used to detect and record the internal pressure of the pressure vessel, which is convenient for testing the pressure resistance performance inside the pressure vessel and increases the testing effect of the pressure vessel.

[0047] like Figure 6 As shown, in some embodiments, a slide plate 503 is sleeved on the outer peripheral side of the slide bar 502, an extension plate 504 is installed at the end of the slide bar 502, the extension plate 504 is connected to the detection plate 501, the slide plate 503 is used to resist the extension plate 504, a plug rod 6 is installed on the slide plate 503, and a socket 7 for accommodating the plug rod 6 is provided on the card plate 401. The slide plate 503 includes a cylinder body and a plate body, the cylinder body is installed on the plate body, an annular plate is provided on the cylinder body, the cylinder body is slidably connected with the baffle plate 3, and the rubber sealing ring located on the baffle plate 3 contacts the cylinder body. When the slide plate 503 slides on the baffle plate 3, the annular plate contacts the baffle plate 3, and the sliding of the slide plate 503 is restricted, as shown in FIG. Figure 3 As shown, by setting the annular plate, the maximum sliding limit of the slide plate 503 on the shielding plate 3 is limited, so that Figure 1From the main perspective, the slide bar 502 and the slide plate 503 slide on the shielding plate 3 in the vertical direction. When the insertion rod 6 is inserted into the insertion hole 7, the inner wall of the insertion hole 7 is blocked and restricted by the insertion rod 6, thereby restricting the rotation of the card plate 401 on the shielding plate 3, thereby increasing the stability of the card plate 401 when in use;

[0048] When the device is in use, the slide plate 503 is first slid to make its cylinder contact with the expansion plate 504. At this time, the slide plate 503 and the expansion plate 504 move downward together, and drive the insertion rod 6 to be inserted into the insertion hole 7, so as to limit the rotation of the card plate 401, thereby increasing the stability of the card plate 401 when in use. When the annular plate on the slide plate 503 contacts the baffle plate 3, the sliding of the slide plate 503 is restricted, and the sliding rod 502 is used to drive the expansion plate 504 to continue to move downward, thereby driving the detection plate 501 to continue to move into the pressure vessel, so as to increase the detection effect of the device.

[0049] like Figure 2 , Figure 7 and Fig.13 As shown, in some embodiments, the fixing member 4 further includes a hook plate 402 slidably mounted on the shielding plate 3 to Figure 1 From the main viewing angle, the hook plate 402 is slidably installed on the shielding plate 3 in the horizontal direction. The shape of the hook plate 402 is as follows: Figure 7 As shown, when in use, the hook plate 402 is also used to interfere with the drop formed by the flange and the pressure vessel, further increasing the stability of the shielding plate 3 when in use;

[0050] The hook plate 402 is provided with an inclined block 403, the slide plate 503 is provided with a through groove 404 for accommodating the inclined block 403, a force-applying inclined surface is provided in the through groove 404, and a force-bearing inclined surface parallel to the force-applying inclined surface is provided on the inclined block 403. When the slide plate 503 contacts the inclined block 403, the hook plate 402 is locked with the pressure vessel by the guidance of the force-applying inclined surface and the force-bearing inclined surface. In the normal state, the hook plate 402 is in a state of being away from the pressure vessel.

[0051] When the device is in use, first slide the slide plate 503 to make it close to the baffle plate 3. When the baffle plate 3 drives the insertion rod 6 to be inserted into the insertion hole 7, the inclined block 403 is also accommodated through the through groove 404. During the process, the inner wall of the through groove 404 contacts the force-bearing inclined surface on the inclined block 403 through the force-applying inclined surface, and then the hook plate 402 slides in the direction close to the pressure vessel through the guidance of the two inclined surfaces, so that the hook plate 402 contacts the drop on the pressure vessel, which further increases the stability of the baffle plate 3 when in use.

[0052] like Figure 3 and Figure 4As shown, in some embodiments, a ring plate 505 is slidably mounted on the exhaust pipe 2, the expansion plate 504 is connected to the ring plate 505, a hinged rod 506 is hinged on the ring plate 505, a connecting ring 507 is slidably mounted on the exhaust pipe 2, the detection plate 501 is slidably matched with the connecting ring 507, the free end of the hinged rod 506 is hinged to the detection plate 501, and the ring plate 505 and the connecting ring 507 are both slidably mounted on the exhaust pipe 2 along the axial direction of the exhaust pipe 2, wherein the friction coefficient between the connecting ring 507 and the exhaust pipe 2 is greater than the friction coefficient between the ring plate 505 and the exhaust pipe 2, so that when the two are subjected to external force, the ring plate 505 will slide first, and when the force continues to increase, the two will slide at the same time;

[0053] A plate body is installed on the peripheral side of the connecting ring 507, and a groove body is opened on the plate body. The detection plate 501 is slidably connected with the groove body. Figure 3 As shown;

[0054] When the device is testing, the slide bar 502 pushes the ring plate 505 through the expansion plate 504, so that the ring plate 505 first slides in the direction close to the connecting ring 507. In the process, the hinged rod 506 is also driven to approach the connecting ring 507, and the length of the hinged rod 506 does not change. It can only slide and rotate in the direction away from the connecting ring 507 through the hinge point connected to the detection plate 501 to meet its own movement. Then, the hinged rod 506 pushes the detection plate 501 to move in the direction away from the connecting ring 507, and then the detection plate 501 can move in the direction close to the inner wall of the pressure vessel and contact with the inner wall, so that the pressure sensor 1 fits with the inner wall of the pressure vessel, so that the measured data is more in line with the pressure on the inner wall of the pressure vessel, and the accuracy of the device measurement is further increased.

[0055] When the device needs to be disassembled from the pressure vessel, pull the sliding rod 502 so that the expansion plate 504 pulls the ring plate 505 away from the connecting ring 507, and the hinge rod 506 pulls the detection plate 501 toward the connecting ring 507 until the maximum distance between the detection plates 501 is smaller than the opening of the pressure vessel, thereby facilitating the removal of the device.

[0056] like Fig. 9 and Fig.12As shown, in some embodiments, a connection shell 8 is installed on the peripheral side of the exhaust pipe 2, and a limiting block 10 is slidably installed on the connection shell 8 through a connecting spring 9. The limiting block 10 is provided with an inclined surface, and a through groove 11 is provided on the ring plate 505 and the connecting ring 507. The inner wall of the through groove 11 conflicts with or releases the conflict with the limiting block 10. When the device is in a normal state, the limiting block 10 conflicts with the inner wall of the through groove 11, thereby limiting the sliding of the connecting ring 507. When the device is detected, the expansion plate 504 conflicts with the ring plate 505 so that when the detection plate 501 conflicts with the pressure vessel, the sliding rod 502 is continuously pushed so that The connecting ring 507 contacts the limiting block 10 through the inner wall of the through groove 11, and then the limiting block 10 moves into the connecting shell 8 through the guidance of the inclined surface, so that the connecting spring 9 is deformed, and then the limiting block 10 releases the shielding of the connecting ring 507. The structure formed by the connecting shell 8, the connecting spring 9 and the limiting block 10 has multiple structures on the exhaust pipe 2, so that the sliding mode of the connecting ring 507 and the ring plate 505 on the exhaust pipe 2 is to slide a certain distance and be blocked by the limiting block 10 once, so that the detection plate 501 stays at different parts of the pressure vessel for a longer time, thereby increasing the accuracy of the detection;

[0057] When the device is in use, when the force applied by the slide rod 502 to the ring plate 505 and the connecting ring 507 is less than the force required for the connecting spring 9 to deform, at this time, only the ring plate 505 slides, and the connecting ring 507 does not slide. When the force applied to the slide rod 502 is greater than the force required for the connecting spring 9 to deform, at this time, the two can slide synchronously. By setting the limiting block 10, the ring plate 505 and the connecting ring 507 can slide successively or synchronously, wherein the inner diameter of the expansion plate 504 is greater than the maximum distance between the two limiting blocks 10, which reduces the possibility of being blocked by the limiting block 10 during sliding, thereby increasing the feasibility of the device.

[0058] like Figure 8 As shown, in some embodiments, a side plate 12 is mounted on the expansion plate 504, an arc groove is provided on the side plate 12, a backing plate 13 is slidably mounted on the side plate 12, an arc groove is also provided on the backing plate 13, when the side plate 12 is connected to the backing plate 13, the arc grooves on the two form a connecting hole 14, a connecting rod 15 for inserting into the connecting hole 14 is mounted on the ring plate 505, a connecting bolt 16 is rotatably mounted on the backing plate 13, the connecting bolt 16 is threadedly connected to the side plate 12, a plate body is mounted on the side wall of the ring plate 505, the connecting rod 15 is mounted on the plate body, the connecting rod 15 is L-shaped, the straight section of which is used to hinge the hinge rod 506 and the ring plate 505, and the arc section of which is used to be inserted into the connecting hole 14;

[0059] During use, when the device has been used for a long time, the detection plate 501 and the pressure sensor 1 will inevitably wear out. At this time, the connecting bolt 16 is rotated to release the connection between the pad 13 and the side plate 12, so that the connecting hole 14 is released, and then the expansion plate 504 and the ring plate 505 are released, so that the ring plate 505, the hinge rod 506, the connecting ring 507 and the detection plate 501 can be disassembled, which is convenient for replacement during maintenance, thereby increasing the practicality of the device.

[0060] like Figure 5 , Fig.10 and Fig.11 As shown, in some embodiments, the exhaust pipe 2 includes a main pipe 201 and an extension pipe 202, a groove 17 is provided on the free end of the main pipe 201, a resisting plate 19 is installed in the groove 17 via a resisting spring 18, a blocking block 20 is installed in the groove 17, an L-shaped rod 21 for being inserted into the groove 17 is installed on the extension pipe 202, the blocking block 20 is used to limit the tendency of the L-shaped rod 21 to be away from the groove 17, the width of the groove 17 is greater than or equal to twice the width of the L-shaped rod 21, and the width of the blocking block 20 is consistent with the width of the L-shaped rod 21;

[0061] When in use, align the L-shaped rod 21 with the side of the groove 17 where the blocking block 20 is not installed, and then rotate the extension tube 202 so that the L-shaped rod 21 moves to the position where the blocking block 20 is installed, so that the tendency of the L-shaped rod 21 to move away from the groove 17 is limited by the blocking block 20, and during the insertion process, the top of the L-shaped rod 21 contacts the contact plate 19, so that the contact spring 18 is compressed, so that the contact plate 19 exerts a force on the L-shaped rod 21 to move away from the groove 17, thereby reducing the distance between the L-shaped rod 21 and the groove 17, thereby increasing the connection strength between the main pipe 201 and the extension pipe 202, and detachably connecting the main pipe 201 and the extension pipe 202, firstly, reduces the overall length of the device, which is convenient for transportation of the device, and secondly, when different pressure vessels need to be tested, by installing extension pipes 202 of different lengths, the device can detect pressure vessels of different depths, thereby increasing the practicality of the device.

[0062] like Figure 2 and Figure 7As shown, in some embodiments, there are two hook plates 402, one of which is provided with a clamping cavity 22, and the other hook plate 402 is provided with a clamping plate 23 for being inserted into the clamping cavity 22, and a return spring 24 is installed between the hook plates 402. When in use, the two hook plates 402 are connected to the pressure vessel, which further increases the stability of the baffle plate 3 when in use, and when the hook plate 402 slides, the side wall of the clamping plate 23 is restricted by the inner wall of the clamping cavity 22, thereby increasing the stability of the hook plate 402 when sliding, and a return spring 24 is installed between the two hook plates 402. When the device is released, the slide plate 503 moves away from the baffle plate 3 so that the interference between the through groove 404 and the inclined block 403 is released, and at this time, the return spring 24 is reset, pushing the two hook plates 402 away from each other, releasing the contact with the pressure vessel, facilitating the disassembly of the device, and increasing the practicality of the device.

[0063] like Figure 1 and Figure 6 As shown, in some embodiments, a rubber pad 25 is installed on the baffle plate 3, and the baffle plate 3 is in contact with the pressure vessel through the rubber pad 25. When in use, the baffle plate 3 is in flexibly contact with the pressure vessel through the rubber pad 25, so that when the two are connected, the wear at the baffle plate 3 and the opening of the pressure vessel is reduced, and the deformation compensation of the rubber pad 25 is further used to further increase the sealing effect of the baffle plate 3, thereby increasing the durability of the device.

[0064] like Figure 4 As shown, in some embodiments, a ball 26 is rollingly mounted on the detection plate 501, and the ball 26 rolls with the inner wall of the pressure vessel. When the detection plate 501 is performing detection, it contacts the inner wall of the pressure vessel through the ball 26. When the sliding rod 502 pushes the connecting ring 507 to slide, the rolling of the ball 26 reduces the friction between the two, thereby facilitating driving the sliding of the connecting ring 507.

[0065] When assembling the device, the connecting ring 507 and the ring plate 505 are sleeved onto the exhaust pipe 2, and then the detection plate 501 is installed, the limiting block 10 is pressed to avoid, and the connecting ring 507 is slid to make it close to the expansion plate 504, the connecting rod 15 is moved to be released from the side plate 12, and then the pad 13 is installed through the connecting bolt 16 to connect the ring plate 505 with the expansion plate 504, and then the L-shaped rod 21 is aligned with the groove 17, and the extension pipe 202 is rotated to connect the main pipe 201 with the extension pipe 202;

[0066] When the device is used, the exhaust pipe 2 is inserted into the pressure vessel, the clamping plate 401 is rotated to make it contact with the pressure vessel, and then the slide plate 503 is slid to limit the rotation of the clamping plate 401. At the same time, the hook plate 402 is also in contact with the pressure vessel through the inner wall of the through groove 404. At this time, high-pressure gas is injected into the exhaust pipe 2 to make it enter the pressure vessel. At this time, the slide bar 502 is slid downward to make the ring plate 505 slide in the direction close to the connecting ring 507, thereby making the detection plate 501 move in the direction close to the inner wall of the pressure chamber. After a period of detection, continue Slide the slide bar 502 to continue pushing the detection plate 501 downward. When the connecting ring 507 passes the limiting block 10, it will give the operator an obvious feedback. At this time, stop pushing so that the detection plate 501 can be detected at this height. This cycle is repeated until the detection plate 501 moves to the deepest part of the pressure vessel. After the detection is completed, the slide bar 502 is pulled upward again. When it is pulled to the highest point, continue to pull it so that the hinged rod 506 pulls the detection plate 501 close to the connecting ring 507, so that the maximum diameter of the entire device is smaller than the opening of the pressure vessel, it can be taken out and completed use.
