DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 and Figure 2 As shown, the embodiment of the utility model proposes a compressed air pipeline pressure low limit alarm device, including a protection frame 1, an alarm 2, an abnormal alarm component and a protection adjustment component: the abnormal alarm component includes a partition 3 fixedly connected to the inside of the protection frame 1, a pressure transmitter 4 is fixedly connected to the partition 3, the alarm 2 is fixedly connected to the top of the pressure transmitter 4, and the alarm 2 is electrically connected to the pressure transmitter 4, a high-precision pressure gauge 5 is installed on the inner wall of the protection frame 1, and the high-precision pressure gauge 5 is electrically connected to the pressure transmitter 4;

[0025] The high-precision pressure gauge 5 can transmit an abnormal signal to the alarm 2 through the pressure transmitter 4, so that the alarm 2 generates an audible and visual alarm in time to inform the operator of the abnormal situation in time, so as to facilitate rapid judgment of the operating status of the pneumatic equipment.

[0026] like Figure 1 and Figure 2 As shown, the high-precision pressure gauge 5 adopts a pointer-type remote transmission precision pressure gauge, and the high-precision pressure gauge 5 is connected to a gas pressure transmission pipe 13, and the gas pressure transmission pipe 13 is connected to an external pipeline;

[0027] The high-precision pressure gauge 5 can monitor the high-precision value of the internal pressure of the compressed air transmission pipeline in real time, which is convenient for confirming the detailed value of the pressure in the pipeline.

[0028] like Figure 1 , Figure 2 and Figure 4As shown, the protection adjustment assembly includes a support rail 6 fixedly connected to the top of the protection frame 1, a plurality of limit rods 7 are slidably connected in the support rail 6, a bearing is arranged at the end of the limit rod 7, the bearing fits the inner surface of the support rail 6, a folding baffle 8 is rotatably connected between the plurality of limit rods 7, a driving component is arranged inside the protection frame 1, the driving component includes a rotary motor 9 fixedly connected to the inner wall of the protection frame 1, a lifting screw 10 is fixedly connected to the output end of the rotary motor 9 through a coupling, a slider 11 is threadedly connected to the lifting screw 10, a T-shaped connecting rod 12 is fixedly connected to the slider 11, and the upper end of the T-shaped connecting rod 12 is rotatably connected to the end of the limit rod 7;

[0029] Start the rotary motor 9, and drive the lifting screw 10 to rotate through the rotary motor 9, so that the slider 11 starts to move downward, and then the slider 11 can drive the limit rod 7 to move downward through the T-shaped connecting rod 12, so that the limit rod 7 slides downward in the supporting slide rail 6 and the folding baffle 8 starts to fold, thereby increasing the exposure and brightness of the alarm 2, avoiding excessive blocking of the light alarm of the alarm 2 by the protective device, and ensuring that the operator can perceive the abnormal pressure alarm in time.

In addition, the high-precision pressure gauge 5 can monitor the high-precision value of the internal pressure of the compressed air transmission pipeline in real time, which is convenient for confirming the detailed value of the pressure in the pipeline;

[0036] 2. When the high-precision pressure gauge 5 detects abnormal pressure inside the compressed air transmission pipeline, that is, the alarm 2 starts to generate sound and light alarms, the pressure transmitter 4 can synchronously transmit a control signal to the rotary motor 9 to start the rotary motor 9, and the rotary motor 9 drives the lifting screw 10 to rotate, so that the slider 11 starts to move downward, and then the slider 11 can drive the limit rod 7 to move downward through the T-shaped connecting rod 12, so that the limit rod 7 slides downward in the supporting slide rail 6 and the folding baffle 8 starts to fold, thereby increasing the exposure and brightness of the alarm 2, avoiding excessive blocking of the bright alarm of the alarm 2 by the protective device, and ensuring that the operator can perceive the abnormal pressure alarm in time.
