Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices and equipment, in particular to a grain condition monitoring device for a granary using a gas sensor. Background Art

[0002] A gas sensor is a transducer that converts the volume fraction of a gas into a corresponding electrical signal. The detector head conditions the gas sample through the gas sensor, typically filtering out impurities and interfering gases, and drying or refrigerating the instrument display.

[0003] Application number CN201720413546.9 discloses a gas sensor assembly and a gas monitoring device including the gas sensor assembly, wherein the gas sensor assembly integrates multiple gas sensors. The gas monitoring device also includes one or more signal processing modules and a central controller. The number of the signal processing modules is equal to the number of gas sensors provided in the gas sensor assembly, and the signal processing modules are connected to the gas sensors one-to-one via signal lines. The signal processing modules are connected to the central controller via cables. The gas sensor assembly of the utility model integrates multiple gas sensors to achieve real-time monitoring of multiple gases within a limited space. This allows the gas monitoring device including the gas sensor assembly to monitor multiple gases, thereby improving the efficiency and versatility of the gas monitoring device. The gas monitoring device can be used in boilers or other gas containers in industries such as chemical, metallurgy, and heating to monitor the concentrations of various gases. Since multiple gases may be present in boilers or other monitored containers, the diversity of the monitored gases determines the complexity of the gas monitoring device.

[0004] The gas sensor assembly and the gas monitoring device containing the gas sensor assembly disclosed in the above document have the following defects: during the use of the monitoring device, since the air humidity at each height in the grain pile is different, the equipment can only monitor the humidity state at one height, cannot adjust the height, and lacks flexibility.

[0005] It can be seen from this that the existing gas sensor grain condition monitoring device for a grain silo does not have the function of adjusting the height of the sensor inside the grain pile. It is necessary to improve the existing deficiencies and provide a function that can adjust the height of the sensor inside the grain pile. Utility Model Content

When it is necessary to adjust the height of the device body, loosen the tightening screw, slide the anti-slip rod, and the anti-slip rod slides up and down in the sliding groove of the bottom rod. The anti-slip rod drives the fixed frame and the device body to adjust up and down to detect the humidity at different heights in the granary.

When it is necessary to disassemble the device body, unscrew the bolt to expand the opening of the top fixed frame, and take out the connecting rod in the anti-slip strip, thereby improving the flexibility of the monitoring equipment.

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1 - Figure 8As shown, the utility model is a grain condition monitoring device for a granary using a gas sensor, comprising a device body 1 and a shell cover 2, a rotating structure 3 and a lifting structure 4, the shell cover 2 is clamped on the outer wall of the device body 1, the device body 1 is plugged into the inner wall of the rotating structure 3, the rotating structure 3 is welded to the top of the lifting structure 4, the device body 1 comprises an outer shell 101, the rotating structure 3 comprises a movable block 303, a connecting rod 100 is welded to the lower surface of the outer shell 101, a rotating rod 304 is welded to the outer wall around the movable block 303, a fixing frame 301 is clamped on the outer wall of each two rotating rods 304, a circular groove 302 is opened on one side where the two fixing frames 301 are connected to the rotating rod 304, the rotating rod 304 is rotatably connected to the inner wall of the circular groove 302, and a plurality of anti-slip strips are welded on the inner wall of a fixing frame 301. 306, the connecting rod 100 is inserted into the inner wall of the anti-slip strip 306, and a circular groove 302 is opened on the outer wall of a fixing frame 301 near the anti-slip strip 306, and a bolt 305 is threadedly connected to the inner wall of the circular groove 302. The lower end of the other fixing frame 301 is welded with an anti-slip rod 404, and a bottom rod 401 is provided on the outside of the anti-slip rod 404. The bottom rod 401 is a sleeve-shaped structure, and a slide groove 403 is provided at the upper end of the bottom rod 401. The outer periphery of the anti-slip rod 404 slides with the inner wall of the slide groove. The upper end of the bottom rod 401 is also provided with a clamping ring 402 with an outer diameter smaller than the outer diameter of the bottom rod, and spline teeth 405 are provided on the inner wall of the clamping ring 402. The outer periphery of the anti-slip rod 404 is provided with a spline groove 407 adapted to the spline teeth 407, and the spline teeth 405 and the spline groove 407 slide in the axial direction of the bottom rod.

[0030] In addition, a tightening screw 406 is threadedly connected to the clamping ring 402, and the axial direction of the tightening screw 406 is consistent with the radial direction of the clamping ring. When tightening the tightening screw 406, the inner end of the tightening screw 406 can be tightened in the corresponding spline groove of the anti-slip rod 404, thereby fixing the position of the anti-slip rod 404. When the tightening screw 406 is loosened, the anti-slip rod 404 can slide along the axial direction of the bottom rod.

[0031] The clamping ring and the anti-slip rod are slidably fitted together by spline teeth and spline grooves, which can prevent the anti-slip rod 404 from rotating relative to the bottom rod, making the anti-slip rod more stable during the sliding adjustment process. In addition, compared with the fit between the optical axis and the optical hole, the spline teeth and the spline grooves have a larger contact area, so that before tightening the screws, when no axial force is applied to the anti-slip rod, the anti-slip rod will not move relative to the bottom rod due to its own weight, and the operator can easily tighten the tightening screws to fix the anti-slip rod and the bottom rod.

[0032] During the use of the monitoring device, the anti-slip strip 306 increases the friction force on the connecting rod 100 to reinforce the connection of the outer shell 101 in the fixed frame 301, and the bottom rod 401 is vertically fixed on the ground of the granary. When the height of the device body 1 needs to be adjusted, the anti-slip rod 404 is slid, and the anti-slip rod 404 slides up and down in the slide groove 403 of the bottom rod 401. The sliding cooperation between the spline teeth on the clamping ring and the spline groove on the anti-slip rod helps to improve the sliding stability of the anti-slip rod. The anti-slip rod 404 drives the fixed frame 301 and the device body 1 to adjust up and down to detect the humidity at different heights in the granary. When the anti-slip rod is adjusted to the specified height, the tightening screw is tightened to fix the height position of the anti-slip rod.

[0033] When the angle of the device body 1 needs to be adjusted for detection, the top fixing frame 301 is rotated, and the fixing frame 301 drives the movable block 303 and the rotating rod 304 to rotate and adjust in the circular groove 302 at the bottom. When the device body 1 needs to be disassembled, the bolt 305 is unscrewed to expand the opening of the top fixing frame 301, and the connecting rod 100 in the anti-slip strip 306 can be taken out, thereby improving the flexibility of the monitoring device.

[0034] A second circuit board 109 is welded to the bottom inner wall of the housing 101. An electrical board 115 is welded to the upper surface of the second circuit board 109.

A circuit board 108 is welded to the lower surface of the conductive block 111. An induction light 113 is welded to the outer wall of the circuit board 108 near the conductive block 111. Three cables 114 are welded to the outer wall of the induction light 113. A speaker 116 is welded to the other ends of the three cables 114. The purpose of this arrangement is that when the monitoring device is in use, the switch key 106 is pressed, the switch key 106 controls the conductive block 111 to turn on, the conductive block 111 controls the circuit board 108 to be in a power supply state, the sensor light 113 on the circuit board 108 lights up to indicate the monitoring status of the gas in the air by the sensor 112, and the conductive block 111 simultaneously powers the speaker 116 through three cables 114. When the gas concentration is too high, the sensor 112 responds to the conductive block 111, and the conductive block 111 responds to the speaker 116 through the cable 114. Finally, the speaker 116 issues an alarm through the sound playback slot 105, thereby enhancing the practicality of the device.

[0035] A limit block 107 is welded to the bottom inner wall of the housing 101 near the sound emitter 116. A sound emission slot 105 is provided on the outer wall of the housing 101 near the sound emitter 116. This arrangement ensures that during use of the monitoring device, the sensor 112 reacts to the conductive block 111, which in turn reacts to the sound emitter 116 via the cable 114. Ultimately, the sound emitter 116 generates an alarm through the sound emission slot 105.

[0036] Clamps 110 are welded to the bottom inner wall of housing 101, near circuit board 108. Circuit board 108 is clamped between clamps 110 and housing 101. Sensors 112 are welded to the upper surface of circuit board 108, near conductive block 111. This arrangement ensures that clamps 110 secure circuit board 108 within housing 101 during use. When components on circuit board 108 need to be removed for maintenance, the three clamps 110 can be moved outward to free circuit board 108 from its restraints.

[0037] The lower surface of the housing 101 is provided with an energy storage slot 102, with a retaining spring 103 welded to one inner wall of the energy storage slot 102. This arrangement allows the battery 104 to be installed in the energy storage slot 102 via the retaining spring 103 during use of the monitoring device, and the electrical board 115 is connected to the battery 104 to provide power to the conductive block 111 and the circuit board 108.

[0038] Battery 104 is secured to the retaining spring 103 of energy storage tank 102, located directly below electrical plate 115. An on / off switch 106 is located on the lower surface of housing 101, near conductive block 111. This ensures that, during use of the monitoring device, electrical plate 115 connects to battery 104 to power conductive block 111 and circuit board 1 108. Pressing on on / off switch 106 activates conductive block 111, which in turn powers circuit board 108.

[0039] The outer wall of the housing 101 is fitted with a cover 201. Several ventilation grooves 202 are defined along the perimeter of the cover 201, and a snap-fitting slot 203 is defined on the bottom inner wall of the cover 201. The top of the housing 101 snaps into the snap-fitting slot 203 of the cover 201. This arrangement ensures that, during use, gas flows inward through the ventilation grooves 202, where it is sensed and identified by the sensor 112. The housing 101 is then snapped onto the inner wall of the cover 201, making disassembly very convenient.

[0040] When the height of the device body 1 needs to be adjusted, the anti-slip bar 404 is slid, and the anti-slip bar 404 slides up and down in the sliding groove 403 of the bottom bar 401, and the clamping ring 402 limits and fixes the anti-slip bar 404 so that it is not easy to slide down. The anti-slip bar 404 drives the fixing frame 301 and the device body 1 to adjust up and down to detect the humidity at different heights in the granary. When the angle of the device body 1 needs to be adjusted for detection, the top fixing frame 301 is rotated, and the fixing frame 301 drives the movable block 303 and the rotating rod 304 to rotate and adjust in the circular groove 302 at the bottom. When the device body 1 needs to be disassembled, the bolt 305 is unscrewed to expand the opening of the top fixing frame 301, and the connecting rod 100 in the anti-slip bar 306 can be taken out, thereby improving the flexibility of the monitoring equipment.
