Description

Technical Field

[0001] This solution belongs to the technical field of test tables, specifically involving a tank pressure fire safety inspection test table. Background Technology

[0002] Utility model patent CN210953610U discloses a pressure gauge for testing the strength of a pressure tank with a quick-connect structure. The gauge includes a fixed cylinder and a pressure gauge. A connecting cylinder is fixedly installed on the lower side of the outer wall of the pressure gauge. The inner wall of the fixed cylinder has symmetrically formed sliding grooves and an annular groove. A slider is symmetrically fixedly installed on the lower side of the outer wall of the connecting cylinder. A movable block is symmetrically inserted into the upper side of the outer wall of the connecting cylinder. An annular plate is fixedly installed on the upper side of the movable block, and a fixing ring is fixedly installed on the outer side of the annular plate. In this utility model, the slider is moved from the sliding groove into the annular groove and rotated 90 degrees. Then, the movable block can be inserted into the sliding groove to fix the position of the pressure gauge. This method is simple and convenient to operate, enabling quick installation and removal of the pressure gauge.

[0003] However, this device has certain shortcomings. When using the existing tank pressure fire safety inspection and test gauge, the device is not convenient to adjust and install on tanks with flanges of different diameters. At the same time, gas enters the pressure gauge and dust enters the device. Utility Model Content

[0004] The purpose of this solution is to provide a pressure fire safety inspection test gauge for tanks to address the problems of the device being inconvenient to adjust when installed on tanks with flanges of different diameters, and the possibility of gas entering the pressure gauge and dust entering the device's interior.

[0005] To achieve the above objectives, this solution provides a tank pressure fire safety inspection test gauge, including a base, a rubber pad bonded inside the base, a connecting pipe fixedly connected to the upper end of the base, a test gauge fixedly connected to the upper end of the connecting pipe, a pressure relief valve installed inside the connecting pipe, a filter mechanism installed inside the base, and a fixing mechanism installed on the connecting pipe.

[0006] The principle of this solution is as follows: During use, the device is moved to contact the flange and rubber gasket of the tank. During this process, the flange squeezes the clamping rod, causing the clamping rod to slide into the sliding sleeve, thus compressing the torsion spring. When the flange and the clamping rod are misaligned, the torsion spring returns to its original position, causing the clamping rod to extend out of the sliding sleeve and be positioned below the flange protrusion. Then, the screw ring is rotated, causing the clamping rod to extend and retract within the sliding sleeve. The rotation of the screw ring and the connecting pipe creates a threaded motion, which in turn causes the connecting rod to move the sliding sleeve. This allows the entire device to be easily fixed at flanges of tanks with different opening sizes. When the pressure relief valve is opened, the airflow drives the blades to rotate the support shaft, which in turn causes the square rod to rotate the sliding ring. This causes the scraper to slide on the filter screen surface, brushing the filter screen to prevent impurities from entering the connecting pipe and to prevent the filter screen from clogging, thus ensuring filtration efficiency.

[0007] The technical effect of this solution is that the airflow drives the blades to rotate the support shaft, which in turn causes the square rod to rotate the slip ring, which in turn causes the scraper to slide on the filter screen surface and brush the filter screen, preventing impurities from entering the connecting pipe and preventing the filter screen from clogging, thus ensuring filtration efficiency.

[0008] The device moves by extending and retracting within the sliding sleeve via a lever, and by rotating the screw ring and connecting pipe to create a threaded motion. This allows the connecting rod to move the sliding sleeve, making the entire device easy to fix at the flanges of tanks with different opening sizes.

[0009] Furthermore, the filtration mechanism includes a filter screen. The filter screen is connected to an internal sliding tube of the base. A spring is installed inside the base, with one end fixedly connected to the filter screen and the other end fixedly connected to the base. A support shaft is mounted inside the filter screen via a sealed bearing. A blade is fixedly connected to the outer side of the support shaft. A square rod is fixedly connected to the lower end of the support shaft. A baffle is fixedly connected to the lower end of the square rod. A slip ring is slidably connected to the outer side of the square rod, and a compression spring is provided thereon. A scraper is fixedly connected to the upper end of the slip ring, and the scraper is slidably connected to the filter screen. Airflow drives the blade to rotate the support shaft, which in turn causes the square rod to rotate the slip ring. This causes the scraper to slide on the surface of the filter screen, brushing it to prevent impurities from entering the connecting tube and to avoid clogging the filter screen, thus ensuring filtration efficiency.

[0010] Furthermore, a guide block is fixedly connected to the surface of the filter screen, and the guide block is slidably connected to the base. The guide block guides the movement of the filter screen.

[0011] Furthermore, one end of the compression spring is fixedly connected to the baffle, and the other end of the compression spring is fixedly connected to the slip ring. By setting the compression spring, the slip ring is elastically pushed upward.

[0012] Furthermore, the fixing mechanism includes a connecting ring, which is movably connected to the outer side of the connecting pipe. A threaded ring is threaded onto the outer side of the connecting pipe. A connecting rod is fixedly connected to the lower end of the connecting ring, and a sliding sleeve is fixedly connected to the lower end of the connecting rod. A locking rod is slidably connected inside the sliding sleeve, and a guide pin is fixedly connected to the lower end of the locking rod. The guide pin and the sliding sleeve are slidably connected, and a torsion spring is installed inside the sliding sleeve. By extending and retracting the locking rod within the sliding sleeve, and by rotating the threaded ring and connecting pipe, the connecting rod drives the sliding sleeve to move, making the entire device easy to fix at flanges of tanks with different opening sizes.

[0013] Furthermore, a slider is fixedly connected to the upper end of the screw ring, and the slider and the connecting ring are slidably connected. By setting the slider, the friction between the connecting ring and the screw ring is reduced.

[0014] Furthermore, one end of the torsion spring is fixedly connected to the sliding sleeve, and the other end of the torsion spring is fixedly connected to the locking rod. By setting the torsion spring, the locking rod can be easily reset. Attached Figure Description

[0021] The implementation examples are basically as follows Figure 1 , Figure 2 As shown, this embodiment provides a tank pressure fire safety inspection test gauge, including a base 1, a rubber pad 2 bonded inside the base 1, a connecting pipe 3 fixedly connected to the upper end of the base 1, a test gauge 4 fixedly connected to the upper end of the connecting pipe 3, a pressure relief valve 5 installed inside the connecting pipe 3, a filter mechanism 6 installed inside the base 1, and a fixing mechanism 7 installed on the connecting pipe 3.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, the filter mechanism 6 includes a filter screen 61. The filter screen 61 is connected to an internal sliding tube in the base 1. A guide block 62 is fixedly connected to the surface of the filter screen 61, and the guide block 62 is slidably connected to the base 1. The guide block 62 guides the movement of the filter screen 61. A spring 63 is installed inside the base 1, with one end fixedly connected to the filter screen 61 and the other end fixedly connected to the base 1. A support shaft 64 is installed inside the filter screen 61 via a sealed bearing. A blade 65 is fixedly connected to the outer side of the support shaft 64. A square rod 66 is fixedly connected to the lower end of the support shaft 64, and a baffle 67 is fixedly connected to the lower end of the square rod 66. A slip ring 68 is slidably connected to the outer side of the square rod 66, and a compression spring 69 is provided on the outer side of the square rod 66. One end of the compression spring 69 is fixedly connected to the baffle 67, and the other end of the compression spring 69 is fixedly connected to the slip ring 68. By setting the compression spring 69, the slip ring 68 is elastically pushed upward. A scraper 610 is fixedly connected to the upper end of the slip ring 68. The scraper 610 is slidably connected to the filter screen 61. The airflow drives the blade 65 to drive the support shaft 64 to rotate, which in turn causes the square rod 66 to drive the slip ring 68 to rotate, which in turn causes the scraper 610 to slide on the surface of the filter screen 61 and brush the filter screen 61, preventing impurities from entering the connecting pipe 3 and preventing the filter screen 61 from clogging, thus ensuring filtration efficiency.

[0023] like Figure 1 , Figure 2 , Figure 4As shown, the fixing mechanism 7 includes a connecting ring 71. The connecting ring 71 is movably connected to the outside of the connecting pipe 3. A threaded ring 72 is threadedly connected to the outside of the connecting pipe 3. A slider 73 is fixedly connected to the upper end of the threaded ring 72. The slider 73 and the connecting ring 71 are slidably connected. By setting the slider 73, the friction between the connecting ring 71 and the threaded ring 72 is reduced. A connecting rod 74 is fixedly connected to the lower end of the connecting ring 71. A sliding sleeve 75 is fixedly connected to the lower end of the connecting rod 74. A locking rod 76 is slidably connected inside the sliding sleeve 75. The lower end of the locking rod 76 is fixedly connected to the lower end of the connecting rod 76. The device is fixedly connected by a guide pin 77, which is slidably connected to a sliding sleeve 75. A torsion spring 78 is installed inside the sliding sleeve 75. One end of the torsion spring 78 is fixedly connected to the sliding sleeve 75, and the other end of the torsion spring 78 is fixedly connected to a locking rod 76. By setting the torsion spring 78, the locking rod 76 can be easily reset. The locking rod 76 extends and retracts within the sliding sleeve 75, and the screw ring 72 and the connecting pipe 3 make threaded movements, thereby causing the connecting rod 74 to drive the sliding sleeve 75 to move. This makes it easy to fix the entire device at the flange of a tank with a different opening size.

[0024] The specific implementation process of this utility model is as follows: In use, the device is moved to contact the flange and rubber gasket 2 of the tank. During this process, the flange squeezes the locking rod 76, causing the locking rod 76 to slide into the sliding sleeve 75, which compresses the torsion spring 78. When the flange and the locking rod 76 are misaligned, the torsion spring 78 resets, causing the locking rod 76 to extend out of the sliding sleeve 75 and be positioned below the flange protrusion. Then, the screw ring 72 is rotated, and the locking rod 76 extends and retracts within the sliding sleeve 75. The screw ring 72 and the connecting pipe 3 are rotated to make threaded movements, which in turn causes the connecting rod 74 to move the sliding sleeve 75. This makes it easy to fix the entire device at the flange of tanks with different opening sizes. When the pressure relief valve 5 is opened, the airflow drives the blade 65 to rotate the support shaft 64, which in turn causes the square rod 66 to rotate the sliding ring 68. This causes the scraper 610 to slide on the surface of the filter screen 61, brushing the filter screen 61 to prevent impurities from entering the connecting pipe 3 and to prevent the filter screen 61 from clogging, thus ensuring filtration efficiency.

[0025] The airflow drives the blades 65 to rotate the support shaft 64, which in turn causes the square rod 66 to rotate the slip ring 68. This causes the scraper 610 to slide on the surface of the filter screen 61, brushing the filter screen 61 to prevent impurities from entering the connecting pipe 3 and to prevent the filter screen 61 from clogging, thus ensuring filtration efficiency.

[0026] The device moves by extending and retracting within the sliding sleeve 75 via the locking rod 76, and by rotating the screw ring 72 and the connecting pipe 3 to make threaded movements, thereby causing the connecting rod 74 to drive the sliding sleeve 75 to move, making the entire device easy to fix at the flange of tanks with different opening sizes.
