DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figure 1-Figure 8 A hinged beam with a pressure relief overflow alarm function comprises a beam body 1, a pressure channel 2 for fluid to pass through is vertically arranged on the surface of the beam body 1, a liquid outlet pipe 3 is fixedly installed at the bottom of the pressure channel 2, a liquid inlet pipe 4 is fixedly installed on the side wall at the top of the pressure channel 2, a through hole 5 communicating with the interior of the pressure channel 2 is vertically opened on the upper surface of the pressure channel 2, a piston block 6 is inserted in the through hole 5 for sliding sealing, an overflow port 7 is horizontally opened on the side wall at the top of the pressure channel 2, an overflow pipe 8 for covering the overflow port 7 is fixedly installed on the side wall at the top of the pressure channel 2, a placement plate 28 is fixedly installed on the surface of the pressure channel 2, a liquid storage box 9 is fixedly installed on the upper surface of the placement plate 28, and the overflow pipe 8 is connected to the liquid storage box 9.

[0033] A threaded rod 10 is vertically rotatably installed at the top of the pressure channel 2, and a slide plate 11 is threadedly sleeved on the threaded rod 10. A first telescopic spring 12 is fixedly installed on the lower surface of the slide plate 11. The two ends of the first telescopic spring 12 are fixedly connected to the lower surface of the slide plate 11 and the upper surface of the piston block 6 respectively. The slide plate 11 is limited in rotation by a limiting component. The limiting component includes a plurality of limiting rods 14 vertically fixedly installed on the upper surface of the pressure channel 2. The slide plate 11 is slidably sleeved on the plurality of limiting rods 14. A limiting component is provided on the top of the pressure channel 2. The limiting component is used to limit the moving distance of the piston block 6. The limiting component includes an L-shaped limiting rod 15 fixedly installed on the upper surface of the pressure channel 2. A sliding groove 16 is vertically opened on the side wall of the piston block 6. One end of the limiting rod 15 is slidably configured in the sliding groove 16. A pressure sensor is provided in the pressure channel 2 (not shown, and the pressure sensor is a prior art, and its working principle is not described in detail here). An alarm 13 electrically connected to the pressure sensor is provided on the upper surface of the beam body 1.

[0034] In the initial state, the top wall of the slide groove 16 opened on the side wall of the piston block 6 will be against the upper surface of the limit rod 15 under the elastic potential energy of the first telescopic spring 12. At this time, the piston block 6 will block the overflow port 7, and then pass the liquid from the liquid inlet pipe 4 into the pressure channel 2. If the pressure in the pressure channel 2 is relatively large, the piston block 6 will gradually move upward under the action of the pressure, and the first telescopic spring 12 will gradually shrink until the piston block 6 moves up to no longer block the overflow port 7. The overflow port 7 will be in an open state, and part of the liquid in the pressure channel 2 will enter the overflow pipe 8 from the overflow port 7, and finally flow into the liquid storage box 9, thereby achieving the effect of pressure relief overflow and avoiding damage to the equipment due to excessive pressure.

[0035] As the pressure decreases, the pressure on the piston block 6 will gradually weaken, and the piston block 6 will quickly move down and reset under the elastic potential energy of the first telescopic spring 12, and the piston block 6 will block the overflow port 7 again.

[0036] At the same time, when the threaded rod 10 is rotated, the slide plate 11 threadedly connected to the threaded rod 10 will move vertically under the limiting action of the multiple limiting rods 14. Since the piston block 6 cannot move downward due to the limiting action of the limited displacement rods 15, the first telescopic spring 12 will shrink and deform. The deformation of the first telescopic spring 12 will change, and its elastic potential energy will also change. The larger the deformation, the greater the elastic potential energy, so that the piston block 6 can move under the required pressure, thereby improving practicality.

[0037] The pressure sensor can monitor the pressure in the pressure channel 2 in real time. When the pressure sensor detects that the pressure exceeds the set dangerous pressure value, it will trigger the alarm 13 to send out an audible and visual alarm signal to remind the operator to take timely measures. The alarm 13 uses high-brightness lights and loud sounds to ensure that it can be clearly perceived even in a noisy working environment.

[0038] A turntable 17 is fixedly mounted on the top of the threaded rod 10 through a plurality of connecting rods 29 , and the surface of the turntable 17 is provided with anti-skid patterns.

[0039] The threaded rod 10 can be controlled to rotate by rotating the turntable 17, making the rotation of the threaded rod 10 more convenient. The anti-skid pattern can increase the friction between the contact surface of the turntable 17 and the operator's palm to prevent the operator from slipping out of the hand.

[0040] An adsorption assembly is provided on the threaded rod 10, and the adsorption assembly is used to lock the threaded rod 10. The adsorption assembly includes a mounting plate 18 fixedly sleeved on the threaded rod 10, a moving rod 19 and a suction cup 20 fixedly installed at the bottom end of the moving rod 19. A through hole is opened on the surface of the mounting plate 18, and the moving rod 19 is vertically slidably inserted in the through hole. A rubber ring 30 is bonded to the wall of the through hole, and the surface of the moving rod 19 is in sliding contact with the inner ring wall of the rubber ring 30.

[0041] The rubber ring 30 has certain viscosity and elasticity, so that it can form a certain elastic clamping on the moving rod 19. When the suction cup 20 is not in contact with anything else, the moving rod 19 will not move vertically under the elastic clamping of the rubber ring 30. When the threaded rod 10 is rotated until the first telescopic spring 12 is stretched to a suitable state, the moving rod 19 can be controlled to move downward with the suction cup 20, so that the suction cup 20 is tightly pressed against the upper surface of the pressure channel 2. The suction cup 20 will be deformed by the pressing force, and the gas in the suction cup 20 will slip out from the gap between itself and the contact surface of the pressure channel 2, thereby completing the adsorption, which can limit the rotation of the threaded rod 10 and prevent the threaded rod 10 from rotating due to the influence of external forces, thereby causing the telescopic state of the first telescopic spring 12 to change.

[0042] A hollow rod 21 with a closed top is vertically fixedly installed on the inner top wall of the liquid storage box 9, a piston rod 22 is vertically slidably and sealably inserted in the hollow rod 21, a liquid passage tube 23 is fixedly installed on the top of the hollow rod 21, the top of the liquid passage tube 23 passes through the liquid storage box 9, and a transparent spherical shell 24 is fixedly installed, a telescopic component is provided in the hollow rod 21, and is filled with brightly colored and eye-catching pigments, the telescopic component includes a second telescopic spring 25, the two ends of the second telescopic spring 25 are respectively fixedly connected to the top of the piston rod 22 and the inner top wall of the hollow rod 21, the piston rod 22 is controlled to move upward by a floating assembly, and the floating assembly includes a floating plate 26 that can float on the liquid surface, the floating plate 26 is located below the piston rod 22, and a plurality of liquid passages 27 for the passage of liquid are opened on the surface.

[0043] In the initial state, the piston rod 22 will be at the bottom due to the elastic potential energy of the second telescopic spring 25. At this time, the space volume between the top of the piston rod 22 and the top wall of the hollow rod 21 is the largest and the pressure is the smallest. The pigment will be located in this space, and the liquid entering the liquid storage box 9 from the overflow pipe 8 will gradually increase, the liquid level will gradually rise, and the floating plate 26 will also move up with the liquid level. When the floating plate 26 moves up to a certain height, the upper surface of the floating plate 26 will be against the bottom of the piston rod 22 and push the piston rod 22 to move up. When the piston rod 22 moves up, the second telescopic spring 25 will contract, the space volume will become smaller, and the pressure will increase. The pigment located in the space volume will enter the transparent spherical shell 24 from the liquid passing pipe 23. When the spherical shell 24 is filled with pigment, it means that the amount of liquid that the liquid storage box 9 can collect is about to reach the maximum amount, thereby reminding the operator to deal with the liquid in the liquid storage box 9 in time.

[0044] In the present invention, in the initial state, the piston block 6 will block the overflow port 7, and then the liquid will be passed from the liquid inlet pipe 4 into the pressure channel 2. If the pressure in the pressure channel 2 is relatively high, the piston block 6 will gradually move up under the action of the pressure, and the first telescopic spring 12 will gradually shrink until the piston block 6 moves up to no longer block the overflow port 7. The overflow port 7 will be in an open state, and part of the liquid in the pressure channel 2 will enter the overflow pipe 8 from the overflow port 7 and finally flow into the liquid storage box 9, thereby achieving the effect of pressure relief and overflow, avoiding damage to the equipment due to excessive pressure. As the pressure decreases, the pressure on the piston block 6 will gradually weaken, and the piston block 6 will quickly move down and reset under the elastic potential energy of the first telescopic spring 12, and the piston block 6 will block the overflow port 7 again. At the same time, when When the threaded rod 10 is rotated, the slide plate 11 threadedly connected to the threaded rod 10 will move vertically under the restriction of the restriction component, and the first telescopic spring 12 will shrink and deform, and the deformation of the first telescopic spring 12 will change, and its elastic potential energy will also change. The larger the deformation, the greater the elastic potential energy, so that the piston block 6 can move under the required pressure, which improves practicality. The pressure sensor can monitor the pressure in the pressure channel 2 in real time. When the pressure sensor detects that the pressure exceeds the set dangerous pressure value, it will trigger the alarm 13 to send out an audible and visual alarm signal to remind the operator to take timely measures. The alarm 13 uses high-brightness lights and loud sounds to ensure that it can be clearly perceived even in a noisy working environment.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
