Description

Technical Field

[0001] The utility model relates to a monitoring device, in particular to a gas cabinet piston tilt monitoring device. Background Art

[0002] A gas tank is a steel container for storing industrial and civilian gas. There are two types: wet gas tanks and dry gas tanks. A gas tank relies on the up and down movement of the piston to change the volume inside the tank. When the piston of the gas tank tilts during operation, the gas tank piston may get stuck, the pressure inside the tank may be over-pressured or under-pressured. In severe cases, the gas tank may cause the piston to hit the top, bottom out, or scratch the piston bladder, causing gas leakage, thereby causing a safety accident and causing heavy losses. Therefore, during the operation of the gas tank, it is necessary to closely monitor the inclination of the gas tank piston to ensure effective and safe production.

[0003] For example, a gas tank piston inclination measuring device disclosed in the Chinese patent publication number CN218494743U includes a gas tank device, the inclination detection component on the gas tank device monitors the inclination of the piston body in real time, and the support adjustment component on the inclination detection component supports and adjusts the inclination detection component. It is characterized in that the gas tank device includes a gas tank body, the piston body in the gas tank body is located on one side of the limit component, the setting of the limit component limits the piston body, the setting of the monitoring component on the gas tank body monitors the running state of the piston body in real time, and the inclination detection component includes an explosion-proof laser piston balance detector. The inclination measuring device of the gas tank piston is provided with a limit component and a monitoring component. When the pressure sensor reaches the set pressure value, the gas input is stopped to protect the gas tank body, and the running state of the piston body in the gas tank body is monitored with the assistance of the monitoring component.

[0004] Some problems were found during use of the above-mentioned existing gas tank piston inclination measuring device. A large number of sensors were used, resulting in a high cost. Secondly, a laser piston balance detector was used. The inclination of the piston would cause the reflector to shift. At this time, the laser reflection position would change, and the reflected laser could not be received again. Although the piston inclination could be known, the inclination angle of the piston could not be accurately known. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-4 The utility model provides a technical solution: a gas tank piston tilt monitoring device, including a gas tank body 1, a piston 101 is slidably installed in the gas tank body 1, a fixed plate 201 is fixedly connected to the piston 101, a multi-section telescopic rod 2 is fixedly connected to the fixed plate 201, a ball seat 204 is fixedly connected to the upper end of the multi-section telescopic rod 2, a rolling ball 205 is rotatably installed in the ball seat 204, a measuring plate 3 is fixedly connected to the top of the gas tank body 1 by bolts, and a plurality of extrusion rings 303 are arranged below the measuring plate 3.

[0022] In this embodiment, the ball 205 cooperates with the measuring disk 3. When the piston 101 is in a normal horizontal state, the multi-section telescopic rod 2 is in a vertical state, so that the up and down movement of the piston 101 will not drive the ball 205 to move. After the piston 101 tilts, the piston 101 will drive the multi-section telescopic rod 2 to tilt, so that the multi-section telescopic rod 2 will drive the ball 205 to deflect. The ball 205 deflects against the bottom surface of the measuring disk 3 and touches the extrusion ring 303. The extrusion ring 303 is compressed and sends a signal. At this time, the height of the piston 101 is detected to know the height X of the piston 101 and the measuring disk 3. The ball 205 touches the extrusion ring 303, and the radius of the extrusion ring 303 is Y. According to the trigonometric function TanA=Y / X, the offset angle of the piston 101 can be calculated.

[0023] Among them, in order to achieve the purpose of always keeping the rolling ball 205 under the measuring disk 3, the present device adopts the following technical solutions: the inner wall of the gas tank body 1 is fixedly connected to the limit block 102, the limit block 102 cooperates with the piston 101, the outer wall of the fixed disk 201 is fixedly connected to the position near the upper and lower end edges, and the fixed disk 201 is sleeved with a return spring 203, and the return spring 203 is located between the two spring pads 202.

[0024] The return spring 203 can provide a certain thrust for the spring pad 202. The spring pad 202 will drive the fixed plate 201 to extend due to the thrust, thereby driving the ball 205 to always be under the measuring plate 3. The fixed plate 201 can cooperate with bolts to fix the multi-section telescopic rod 2 on the piston 101. The limit block 102 cooperates with the piston 101 to prevent the piston 101 from moving up to the top of the gas tank body 1, thereby avoiding interference between the fixed plate 201 and the piston 101.

[0025] Among them, in order to achieve the purpose of monitoring the inclination of the piston 101, the present device adopts the following technical scheme: a fixed foot 301 is fixedly connected to the outer wall of the measuring disk 3, a central touch pressure switch 302 is fixedly connected to the center of the bottom of the measuring disk 3, a plurality of extrusion rings 303 with gradually increasing diameters are all sleeved around the central touch pressure switch 302, a detection touch pressure switch 304 is fixedly connected to the top of the extrusion ring 303, and the detection touch pressure switch 304 is embedded and installed under the measuring disk 3.

[0026] By opening an annular groove opposite to the squeezing ring 303 under the measuring disk 3, the detection touch pressure switch 304 is embedded and installed in the annular groove, the upper edge of the squeezing ring 303 is aligned with the measuring disk 3, and the lower edge of the squeezing ring 303 is rounded, so that the ball 205 can smoothly press the squeezing ring 303 to deviate outward, and the central touch pressure switch 302 cooperates with the ball 205. Under normal conditions, the ball 205 will always squeeze the central touch pressure switch 302. After the piston 101 deviates and drives the ball 205 to move, the center touch pressure switch 302 of the ball 205 displacement will lose the squeeze, thereby sending a signal alarm, indicating that the piston 101 has deviated. The detection touch pressure switch 304 connected to each squeezing ring 303 is separately connected to the control system. When the ball 205 touches different squeezing rings 303, the triggered squeezing ring 303 can be accurately known. By calling the radius of this squeezing ring 303, the inclination angle of the piston 101 can be known.

[0027] The working principle and use process of the utility model are as follows: when using the device, it is necessary to place the device in a suitable position. When the piston 101 is in a normal horizontal state, the multi-section telescopic rod 2 is in a vertical state, so that the up and down movement of the piston 101 will not drive the ball 205 to move, and the ball 205 will always be in contact with the central touch-and-pressure switch 302. After the piston 101 tilts, the piston 101 will drive the multi-section telescopic rod 2 to tilt, so that the multi-section telescopic rod 2 will drive the ball 205 to deflect, and the ball 205 will deflect against the bottom surface of the measuring disk 3 and will touch the extrusion ring 303. The extrusion ring 303 will be compressed and send a signal. At this time, the height of the piston 101 and the radius of the extrusion ring 303 that touches the extrusion ring 303 are detected, and the inclination angle of the piston 101 can be calculated according to the trigonometric function.
