[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Please see Figures 1-6 This utility model provides a technical solution: a pressure switch pressure resistance monitoring device with explosion-proof protection, including a main body shell 1, a buffer chamber frame 2, a positioning base 3, a support platform 4, a protective door 5, a guide slide rail 6, a first limiting slide 7, a second limiting slide 8, a pressure application connector 9, a positioning plug 10, a pressure transmission pipeline 11, a pressure pump 12, a touch screen control terminal 13, and an explosion-proof protective window 14;
[0034] Among them, the main body shell 1 is the shell of the pressure resistance monitoring device. The bottom of the main body shell 1 is fixed with a positioning base 3, and a protective door 5 is snapped into the opening on the side wall of the main body shell 1. The main body shell 1 and the positioning base 3 form an independent pressure buffer space.
[0035] A buffer chamber frame 2 is installed on the inner wall of the main body shell 1 of the device, and a track is set on the outer wall of the main body shell 1 of the device. The track is slidably connected to the U-shaped structure of the buffer chamber frame 2. A support platform 4 is installed inside the buffer chamber frame 2. The support platform 4 is an L-shaped frame. The L-shaped structure of the support platform 4 slides with the upper end face of the positioning base 3. The top of the main body shell 1 of the device and the buffer chamber frame 2 are penetrated by an explosion-proof protective window 14. A sealing element is set at the connection between the buffer chamber frame 2 and the protective door 5. The protective door 5 is engaged with the support platform 4. Two guide slide rails 6 and limit slide 7 and limit slide 8 form a rectangular frame structure. The height of limit slide 7 is lower than the height of limit slide 8.
[0036] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the protective door 5 on the side wall of the main body shell 1 of the device is opened. Driven by the protective door 5, the support platform 4 slides along the positioning base 3, so that part of the support platform 4 extends out of the buffer chamber frame 2, providing operating space for placing the pressure switch. The pressure switch to be monitored is placed on the support platform 4. With the help of the two guide slide rails 6 on the support platform 4, the positions of the limiting slide 1 7 and the limiting slide 2 8 are adjusted. The rectangular frame formed by the two and the height difference are used to limit the pressure switch from different dimensions to ensure its initial fixation.
[0037] Connect the pressure application connector 9 to the interface of the pressure switch to further secure the pressure switch and prevent loosening or displacement during monitoring. Close the protective door 5 so that it engages with the main body shell 1 of the device. At this time, the seal at the connection between the buffer chamber frame 2 and the protective door 5 plays its role. Together with the main body shell 1, the positioning base 3 and the buffer chamber frame 2, they form a closed explosion-proof environment, completing the installation preparation.
[0038] Two guide rails 6 are installed on the surface of the support platform 4, and the two guide rails 6 are symmetrically arranged. The guide rails 6 are slidably connected to the limiting slide 7 and the limiting slide 8. The limiting slide 8 has two symmetrical through holes, and the positioning plug 10 is inserted into the through holes. The positioning plug 10 is penetrated by the pressure application connector 9 connected to one end of the pressure transmission pipeline 11, and the other end of the pressure transmission pipeline 11 is connected to the pressure pump 12. The surface of the limiting slide 8 is equipped with a winding roller, and the winding roller of the limiting slide 8 is slidably connected to the pressure transmission pipeline 11. The pressure transmission pipeline 11 penetrates the main body shell 1 of the device, and the connection between the pressure transmission pipeline 11 and the pressure application connector 9 is a threaded connection. The pressure pump 12 is installed on the upper end face of the main body shell 1 of the device, and a touch screen control terminal 13 is installed on the upper end of the main body shell 1 of the device. The touch screen control terminal 13 is electrically connected to the pressure pump 12.
[0039] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the operator issues a start command through the touch screen control terminal 13 on the upper end of the main body shell 1 of the device. Since the touch screen control terminal 13 is associated with the pressure pump 12, the command can drive the pressure pump 12 installed on the upper end of the main body shell 1 of the device to start. The pressure generated by the pressure pump 12 is transmitted through the pressure transmission pipeline 11 that penetrates the main body shell 1 of the device, and then transmitted to the pressure switch through the pressure application connector 9 to simulate the high pressure environment when the pressure switch is actually working.
[0040] During monitoring, operators can observe the status of the internal pressure switch in real time through the explosion-proof protective window 14 that runs through the top of the main body shell 1 and the buffer chamber frame 2. If it is necessary to adjust the pressure application position, the buffer chamber frame 2 can be slidably connected to the track on the outer wall of the main body shell 1 via its U-shaped structure to adjust its position within the main body shell 1, ensuring accurate pressure application. The touchscreen control terminal 13 receives and displays data such as the operating status and output pressure of the pressure pump 12 in real time. Operators use this data to determine the pressure resistance performance of the pressure switch. After monitoring is completed, the equipment is shut down via the touchscreen control terminal 13, ending the entire monitoring process.
[0041] Working principle: When using the pressure switch withstand pressure monitoring device with explosion protection, open the protective door 5 on the side wall of the main body shell 1 of the device, so that the support platform 4 slides along the positioning base 3 and extends part of it out of the buffer chamber frame 2 to facilitate the placement of the pressure switch. After placement, adjust the limiting slide 7 and limiting slide 8 through the two guide slides 6 on the support platform 4. Utilize the rectangular frame formed by the two and the height difference to limit the pressure switch from different dimensions. Then connect the pressure application connector 9 to the pressure switch interface for further fixation.
[0042] The protective door 5 is closed to engage with the main body shell 1. The seal at the connection between the buffer chamber frame 2 and the protective door 5, together with the main body shell 1, the positioning base 3, and the buffer chamber frame 2, forms a closed explosion-proof environment. During operation, the pressure pump 12 is started through the touch screen control terminal 13 at the top of the main body shell 1. The pressure is transmitted through the pressure transmission pipeline 11 that runs through the main body shell 1. The pressure application connector 9 is connected to the pressure switch to simulate a high-pressure environment. The operator can observe through the explosion-proof protective window 14 at the top. The buffer chamber frame 2 can slide and adjust its position along the track on the outer wall of the main body shell 1. The touch screen control terminal 13 displays the status of the pressure pump 12 and the pressure data in real time, thereby judging the pressure resistance of the pressure switch and completing the monitoring, which increases the overall practicality.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
