Detailed Description
Fig. 1 is a schematic structural view of an airbag of a gas holder according to an embodiment of the present invention; fig. 2 is a schematic structural diagram of the gas holder airbag inclination measuring apparatus when inclined. As shown in fig. 1 and 2, the gas chamber airbag inclination measuring device provided by the present embodiment includes a measuring cylinder 20 and a distance meter 10, wherein a plurality of measuring cylinders 20 are configured to be installed on a gas chamber airbag top platform, each measuring cylinder 20 is used for being filled with a measuring liquid 40, the measuring liquids 40 in the respective measuring cylinders 20 are communicated through a communication device, the distance meter 10 is installed on the top of each measuring cylinder 20, and the distance meter 10 is used for detecting the liquid level of the measuring liquid 40 in the measuring cylinder 20.
It should be noted that the measuring liquid 40 in the measuring cylinder 20 is necessarily located in the lower part of the measuring cylinder 20, i.e. the measuring liquid 40 is located below the remaining space outside the space occupied by the measuring liquid 40. The distance meter 10 then measures the distance of the level of the measurement liquid 40 from the distance meter 10, in fact the length of the remaining space, i.e. the level of the measurement liquid 40 in the measuring cylinder 20 is detected.
Specifically, the measuring cylinder 20 is a cylinder, and the top of the measuring cylinder 20 is provided with a mounting flange 12 for mounting the distance measuring device 10. In addition, the present application also does not limit the distance meter 10 to be installed inside or outside the measuring cylinder 20, as long as the distance meter 10 can accurately measure the liquid level of the measuring liquid 40. Specifically, in the present embodiment, the top of the measuring cylinder 20 is not sealed, the distance measuring device 10 is mounted outside the measuring cylinder 20 through a mounting flange 12, and the top of the distance measuring device 10 is provided with a cable through hole 11 for a cable of the distance measuring device 10 to pass through.
The height of the measuring liquid 40 injected into the measuring cylinder 20 is half of the height of the internal space of the measuring cylinder 20. The height of the measuring liquid 40 is measured, and no matter which direction the gas chamber airbag top platform inclines, half of the height of the measuring cylinder 20 in the measuring cylinder 20 can be used for floating of the liquid level, so that the height of the measuring cylinder 20 is effectively utilized.
The plurality of measuring cylinders 20 which can be installed on the top platform of the gas chamber air bag are arranged, the measuring cylinders 20 are filled with the measuring liquid 40, and the measuring cylinders 20 are communicated through the communication device, so that the measuring liquid 40 can flow in each measuring cylinder 20. When the gas chamber air bag inclines, the measuring liquid 40 flows from the upper measuring cylinder 20 to the lower measuring cylinder 20, so that the height of the residual space in each measuring cylinder 20 changes, and the inclination direction and the inclination angle of the gas chamber air bag can be judged by using the length change value of the residual space in each measuring cylinder 20. This gas chamber gasbag slope measuring device adopts indirect non-contact measurement, has avoided sheltering from or the skew is to measuring the hindrance that causes, can effective continuous measurement.
As shown in fig. 1 and 2, it is preferable that a float 30 is further included, and a float 30 is provided in each of the cartridges 20, and the float 30 is configured to float on the surface of the measurement liquid 40.
Although the electromagnetic waves are directly emitted towards the measurement liquid 40 and the echoes are also reflected from the liquid level, the resulting inclination of the gas chamber bladder is not too great, otherwise the echoes directly reflected from the liquid level may not be directly received by the rangefinder 10 and may cause measurement errors. By providing the float 30, the roughness of the surface measured by the distance meter 10 can be properly increased, and even if the electromagnetic wave is not incident perpendicularly along the upper surface of the float 30, because of the diffuse reflection effect of the upper surface of the float 30, the electromagnetic wave can be reflected back to the distance meter 10, thereby facilitating the direct reflection of the electromagnetic wave emitted by the distance meter 10 back to the distance meter 10, and improving the measurement accuracy of the distance meter 10.
As shown in fig. 1 and 2, it is preferable that the float 30 is a sheet-shaped plastic product, and the diameter of the float 30 is smaller than the inner diameter of the measuring cylinder 20.
Adopt slice plastic products, can realize the diffuse reflection to the electromagnetic wave of distancer 10 transmission, even when measuring a section of thick bamboo 20 and take place the slope, slice plastic products also can reflect the electromagnetic wave back to the position at distancer 10 place to make distancer 10 can the accurate height of measuring the remaining space in a measuring section of thick bamboo 20. In addition, the diameter of the float 30 is smaller than the diameter of the measuring cylinder 20, which is advantageous in that the height position of the float 30 relative to the measuring cylinder 20 can be changed rapidly according to the level change of the measuring liquid 40, and the float 30 is prevented from being stuck in the measuring cylinder 20. The response speed of the measuring device is improved, and the measuring reliability is also improved.
Preferably, the measuring liquid 40 is silicone oil.
Silicon oil is used as the measuring liquid 40, the chemical property of the silicon oil is stable, the silicon oil is not easy to volatilize, and after a long time, more measuring liquid 40 still exists in the measuring cylinder 20, so that the long-term use of the gas chamber air bag inclination measuring device is favorably maintained, and meanwhile, the influence on the distance measuring instrument 10 is reduced.
As shown in fig. 1 and 2, it is preferable that the mounting position of each measuring cylinder 20 on the gas tank airbag deck is different from the mounting positions of the other measuring cylinders 20 on the gas tank airbag deck.
The position of each measuring cylinder 20 is different from the positions of the other measuring cylinders 20, so that the transverse distance between the measuring cylinders 20 can be increased, and when the gas chamber air bag inclines, the liquid level height variation of each measuring cylinder 20 can be increased, and more accurate calculation results can be obtained.
In another embodiment, different cartridges 20 may be installed at the same position, for example, a group of two cartridges 20 having a V-shape in side view may be installed at a position, and the two cartridges 20 are connected to each other at the bottom of the V-shape. When the gas chamber air bag is inclined, as long as the inclination direction is not completely vertical to the plane of the V shape, the angles of the two measuring cylinders 20 are changed, and the liquid level of the measuring liquid 40 is also changed. Furthermore, the inclination angle or the inclination distance of the gas tank airbag can be known by measuring the change of the liquid level.
In addition, even if two measuring cylinders 20 are completely installed side by side, the positions of the two measuring cylinders 20 are different, and when the gas tank air bag is inclined, the liquid level of the measuring liquid 40 is different between the two measuring cylinders, but the difference is small, and a distance measuring instrument 10 with higher sensitivity is needed for detection.
As shown in fig. 1 and 2, preferably, the number of the measuring cylinders 20 is four, the four measuring cylinders 20 are uniformly distributed on the gas chamber airbag top platform along an annular shape, and when the gas chamber airbag top platform is in a horizontal posture, each measuring cylinder 20 is vertically arranged.
Specifically, each measuring cylinder 20 may be disposed as close to the edge of the gas chamber airbag top platform as possible, so as to facilitate more directly obtaining the maximum height of inclination of the gas chamber airbag top platform.
The four measuring cylinders 20 are uniformly distributed on the gas chamber air bag top platform, the height difference in one horizontal direction can be obtained by measuring the two measuring cylinders 20 on the diagonal, the height difference in the other horizontal direction can be obtained by using the other pair of measuring cylinders 20 on the diagonal, and the inclined maximum height of the gas chamber air bag top platform is convenient to obtain so as to be beneficial to ensuring the production safety. Moreover, each measuring cylinder 20 is vertically arranged when the gas chamber air bag top platform is in a horizontal state, and the length change of the residual space in the measuring cylinder 20 can be regarded as the height change of the liquid level, so that the measurement precision is improved.
In another implementation, when the gas chamber airbag top platform is in a horizontal posture, each measuring cylinder 20 is not vertically arranged, and the length of the remaining space of the measuring cylinder 20 or the liquid level of the measuring liquid 40 can be measured. For example, when the measuring cylinder 20 is disposed at an angle of 60 ° to the horizontal, the length of the remaining space changes by 1mm, and the level of the measuring liquid 40 changes by 0.866 mm. However, this leads to a complex calculation and/or a reduced accuracy of the measurement, so that the measuring cylinder 20 is preferably arranged vertically.
The number of cartridges 20 illustrated in this embodiment is four and the diagonal lines are perpendicular in order to allow for the convenience of obtaining the maximum height of the gas cabinet airbag top platform tilt from two same directional level changes. In practice, the number of cartridges 20 may be other than a plurality, for example, 2, 3 or 6, and the function of determining the tilt of the cartridge 20 may be implemented. For example, when the number of cartridges 20 is 2, the tilt in other directions can be sensed, in addition to the tilt perpendicular to the line connecting the two cartridges 20 being not sensed. As long as the number of the measuring cylinders 20 is equal to or greater than three, and the measuring cylinders 20 are not arranged in a collinear manner, the inclination in each direction can be sensed, but the method for calculating the maximum inclination height of the gas tank airbag top platform is slightly complicated.
As shown in fig. 1 and 2, it is preferable that the communication means includes a connection pipe connecting the adjacent measuring cartridges 20 and a control valve 53 provided at the connection pipe connecting the adjacent two measuring cartridges 20.
The adjacent measuring cylinders 20 are connected through the connecting pipe, and the control valve 53 is arranged, so that when the measuring liquid 40 is injected into the measuring cylinder 20, the control valve 53 between the measuring cylinders 20 can be opened, the flow of the measuring liquid 40 can be realized through the connecting pipe, and the liquid level between the measuring cylinders 20 is the same when the gas chamber air bag top platform is in a horizontal posture. Of course, when the gas chamber airbag inclination measuring device is used normally, the control valve 53 is also in a conducting state. When one of the measuring cartridges 20 needs to be replaced and maintained, the control valve 53 between the measuring cartridge 20 and the adjacent measuring cartridge 20 can be closed, so that the measuring cartridge 20 can be replaced or maintained conveniently without emptying the measuring liquid 40 between all the measuring cartridges 20 and the connecting pipe, and the convenience of maintenance and replacement is improved.
Specifically, the connection pipe includes a middle connection pipe 52 and an end connection pipe 51, and the end connection pipe 51 is fixedly connected to the bottom of the measuring cylinder 20 and is communicated with the inside of the measuring cylinder 20. The middle connection pipe 52 is connected to the end connection pipe 51 through a connection pipe quick coupling 54, and the connection pipe quick coupling 54 can be a quick plug coupling so as to achieve boundary detachment of the middle connection pipe 52. Wherein the control valve 53 is further installed on the end connection pipe 51, and when the control valve 53 is in a closed state, the measurement liquid 40 does not leak from the connection pipe quick coupling 54.
Preferably, the rangefinder 10 is a laser rangefinder.
The laser range finder is adopted for measurement, so that the emission direction of electromagnetic waves is convenient to control, the scattering of the electromagnetic waves is reduced, and the interference of echo waves of the electromagnetic waves which are not directed to the liquid level or the floater 30 is reduced.
In another implementation, rangefinder 10 may also employ a radar rangefinder, which may be a guided wave radar or a pulse radar with a frequency above 80 GHz. Otherwise, the frequency of the electromagnetic wave is too low, the wavelength is large, and the measurement accuracy is reduced.
As shown in fig. 1 and 2, preferably, the top of the measuring cylinder 20 is further provided with a waterproof vent 21.
By providing the waterproof airing hole 21, the remaining space in the measuring cylinder 20 can communicate with the space outside the measuring cylinder 20. When the gas chamber air bag is inclined, when the liquid level of the measuring liquid 40 in the measuring cylinder 20 is raised or lowered, the residual space in the measuring cylinder 20 can be supplemented with air from the outside of the measuring cylinder 20 or the air can be discharged out of the measuring cylinder 20 in time, so that the influence of the air pressure on the free flow of the measuring liquid 40 is avoided.
The installation process of this embodiment is as follows:
firstly, the measuring cylinder 20 is vertically fixed on a T-shaped baffle plate of a platform at the top of the piston airbag, and the vertical distance from the bottom end of the measuring cylinder 20 to the top of the airbag of the gas chamber is not required so as to be suitable for installation. It should be noted that the four mounting points of the measuring cylinder 20 are located on the same horizontal plane, and the four mounting points are connected to form a square. Next, referring to fig. 1, the connection pipe is fixed below the measuring cylinder 20 through the connection pipe quick coupling 54, the control valve 53 is closed, the measuring liquid 40 is injected into the measuring cylinder 20 to a position of one-half height of the measuring cylinder 20, and then the liquid level of the measuring liquid 40 in each measuring cylinder 20 can be adjusted by the control valve 53 below the measuring cylinder 20. Finally, the distance measuring device 10 is fixed directly above the measuring cylinder 20 via the mounting flange 12.
The measurement principle measured with this embodiment is as follows:
during normal use, the measuring cylinder 20 will tilt to the same height as the gas holder airbag tilts. Referring to fig. 2, for convenience of description, the rightmost measuring cylinder 20 in the drawing is defined as an east measuring cylinder, and the other three measuring cylinders 20 are sequentially a south measuring cylinder, a west measuring cylinder, and a north measuring cylinder in the counterclockwise direction.
