One side of the protective shell is fixedly connected with a plurality of telescopic columns 2, and the outer wall of the telescopic column 2 is provided with a spring 2, and one end of the telescopic column 2 is fixedly connected with an elastic plate. In the utility model, the pressure gauge is protected by the setting of the protective mechanism to increase its service life, and it is protected to a certain extent by the setting of the protective shell. By the coordinated setting of the spring 2, the telescopic rod 2 and the elastic plate, the external impact force is reduced to a certain extent, and the damage of the pressure gauge is avoided, which plays a safety protection effect on the pressure gauge.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] According to an embodiment of the utility model, an intelligent pressure monitoring support device for chemical safety evaluation is provided.

Figure 1-3 As shown, according to an embodiment of the utility model, an intelligent pressure monitoring bracket device for chemical safety evaluation includes a mounting bracket 1, a pressure gauge 2 is installed inside the mounting bracket 1, and the detection probe of the pressure gauge 2 passes through the mounting bracket 1 and is connected to a detection pipeline 3, a pipe clamp 4 is sleeved and installed on the surface of the detection pipeline 3, and the top of the pipe clamp 4 is fixedly connected to the bottom of the mounting bracket 1 by screws, a humidity sensor 9 is fixed at the corner inside the mounting bracket 1, and a PLC controller 10 is fixed to the side wall of the mounting bracket 1, an air inlet nozzle 5 is connected to the left side of the lower part of the mounting bracket 1, and an exhaust nozzle 7 is connected to the right side of the lower part of the mounting bracket, a blowing shell 6 is sleeved and installed at the port of the air inlet nozzle 5, and a blowing fan 16 is installed inside the blowing shell 6, an air inlet 20 is opened on the end face of the blowing shell 6, and a plurality of highly water-absorbent trees are bonded to the inner wall of the blowing shell 6 Grease 19, and an activated carbon adsorption plate 18 is provided in the blowing shell 6 corresponding to the impeller of the blowing fan 16, a movable plate 8 is hinged at the port of the exhaust nozzle 7, and the movable plate 8 is fitted with the port of the exhaust nozzle 7, and multiple surfaces inside the mounting bracket 1 are bonded with rubber buffers 11, and each rubber buffer 11 is against the side of the pressure gauge 2, the output end of the PLC controller 10 is electrically connected to the blowing fan 16, and the humidity sensor 9 is electrically connected to the PLC controller 10. Through the setting of the air inlet 20, it is convenient for the staff to reach into the blowing shell 6 to replace the super absorbent resin 19 to keep the air dry. The activated carbon adsorption plate 18 is on the left side of the impeller of the blowing fan 16, which is easy to absorb moisture in the air. The function of the movable plate 8 is to close naturally in the non-exhaust stage to prevent humid gas from entering the mounting bracket 1;

[0024] In one embodiment, a circular arc concave surface is provided at one end of the rubber buffer 11 facing the pressure gauge 2, and polyurethane foam 12 is filled in the middle position inside the rubber buffer 11, and vibration-damping springs 13 connected to the inner wall of the rubber buffer 11 are respectively provided on the left and right sides of the polyurethane foam 12, and a damper is installed inside the vibration-damping spring 13. When the vibration at the detection pipeline 3 acts on the pressure gauge 2, the multiple rubber buffers 11 inside the mounting bracket 1 can absorb kinetic energy through adaptive deformation and expansion and contraction of the built-in polyurethane foam 12 and vibration-damping spring 13, reduce the adverse effects of the vibration on the pressure gauge 2, and prevent the dial and pointer of the pressure gauge 2 from falling off due to vibration. The kinetic energy absorption structure of the device is based on the mounting bracket 1. Since the mounting bracket 1 is fixedly connected to the detection pipeline 3 by the pipe clamp 4, the installation of the pressure gauge 2 is reinforced. When the vibration at the detection pipeline 3 acts on the pressure gauge 2, the mounting bracket 1 keeps the pressure gauge 2 from falling off, and the rubber buffer 11 realizes kinetic energy absorption, which alleviates the damage to the pressure gauge 2 caused by the vibration.

[0025] In one embodiment, a connecting sleeve 17 is provided on the side of the blowing shell 6 facing away from the blowing port, and the connecting sleeve 17 is socketed with the outer surface of the port of the air inlet nozzle 5.

The setting of the viewing window 15 facilitates the assembly of the pressure gauge 2 and the reading of the value of the pressure gauge 2.

[0027] In one embodiment, a U-shaped opening 14 is provided on the bottom surface of the mounting bracket 1 corresponding to the detection probe of the pressure gauge 2, and an arc-shaped rubber gasket is provided at the arc portion of the U-shaped opening 14.

[0028] In one embodiment, the rubber buffer 11 is an isosceles trapezoidal structure as a whole, and two damping springs are provided. The two damping springs are arranged obliquely inside the rubber buffer 11. Through the arrangement of the damping springs, kinetic energy can be absorbed in an adaptive telescopic manner.

[0029] Working principle:

[0030] When in use, first install the pressure gauge 2 on the surface of the detection pipeline 3 on the chemical equipment, then cover the mounting bracket 1 to the outer periphery of the pressure gauge 2, and fix the mounting bracket 1 with a pipe clamp 4, and install a humidity sensor 9 in the box-type mounting bracket 1 corresponding to the pressure gauge 2, and set a PLC controller 10 and a blowing shell 6 for the humidity sensor 9. When the humidity data detected by the humidity sensor 9 is greater than the preset value of the PLC controller 10, the PLC controller 10 starts the blowing fan 16 inside the blowing shell 6. Due to the pressure difference between the inside and outside of the mounting bracket 1, the outside air is prompted to enter the blowing shell 6 from the air inlet 20, and is absorbed by the super absorbent resin 19 and the activated carbon adsorption plate 1 8 absorbs moisture in the air, so that dry air continuously enters the interior of the mounting bracket 1, and drives the humid gas to be discharged from the exhaust nozzle 7, and the movable plate 8 hinged at the port of the exhaust nozzle 7 can be opened in the exhaust stage and naturally closed in the non-exhaust stage, so as to maintain the dry environment inside the mounting bracket 1 and avoid damage to the pressure gauge 2 in a humid environment. When the vibration at the detection pipeline 3 acts on the pressure gauge 2, the multiple rubber buffers 11 inside the mounting bracket 1 can absorb the kinetic energy through the adaptive deformation and expansion of the built-in polyurethane foam 12 and the shock-absorbing spring 13, reduce the adverse effects of the vibration on the pressure gauge 2, and prevent the dial and pointer of the pressure gauge 2 from falling off due to vibration.
