Device for measuring the content of pressure vessels

Field of technique

The technical solution falls into the field of gas quantity determination and refers to devices for measuring the content of pressure vessels, especially in mobile living spaces, especially in caravans and motorhomes.

Current state of the art

In the area of mobile accommodation, in particular caravans and motorhomes, there are a number of systems that inform the user of the status of installed devices, such as lighting, water heating, battery status, heating or air conditioning control and security, which also allows setting other parameters.

The components of mobile accommodation are also pressure receptacles, for which it is essential to determine the amount of gas contained in these containers. For the measurement of the contents of pressure receptacles, solutions are known, for example, described in GB2126342, VVO2012113776 and US9222825B2, which indicate various constructional performances of devices using different intensities in the propagation of ultrasound in the liquid and gas media, thus permitting the level of the level of the liquid phase in pressure vessels. All these devices, however, require the various meters attached to the wall of the vessel to determine the level of the level of the liquid share, and therefore do not allow continuous information, not the state of the gas, or the connection with the remote control device.

Another option is to determine the amount of gas by weighing, where we can use scales of different constructions, for example, spring hanging scales or techniques for measuring the tension in rigid bodies. With this method, the container must be disconnected from the wiring system, weighed it, and then reconnected backwards, which means that it is demanding manipulation, but it does not allow continuous monitoring of the quantity of gas in the container. The US9404790B2 document describes a device representing a weight sensor of a container or soda that automatically or continuously determines the weight of an installed soda or container intended for a longer-term load. This device, however, is not equipped with a wireless connection to a remote control device, nor to a common control system, nor is it resistant to vibration or transverse acceleration that operates on the device while driving * the mobile space. The US201613175A1 document describes a device that contains a gravity sensor for continuous determination of the weight of gas pressure vessels placed on it, a gas leak sensor, a processor for processing the measured data, and a wireless connection to the receiver at a distance. This device, however, is not resistant to shaking and horizontally acting forces or transverse acceleration, and therefore can not be used for the permanent installation of gas containers in mobile accommodation such as trailers or motorhomes, even while driving. The device is not an integral part of the control system of this facility.

There is no other device that continuously monitors the quantity of gas in the pressure vessel and informs the user about it via the remote device, and at the same time be an integral part of the control system of this facility, which would be waterproof and useful for the continuous installation of gas containers during driving.

The aim of this technical solution is to present the device for the continuous monitoring of the condition of pressure vessels, which is permanently connected to gas containers, as well as to the control system of this facility, while at the same time it enables safe attachment of the vessel, together with the resistance to shaking and the operation of horizontal forces to which comes in while driving.

The essence of the technical solution

A specific goal will be achieved through a technical solution, which is a device for measuring the content of pressure vessels, especially in mobile living spaces. This device consists of a tension measuring instrument in rigid bodies, which has a supporting element and base where the battery box is equipped with a battery pack, an electronic box, which is equipped with an electronic module and a tensometer sensor. The essence of the solution is that the carrier element is in the form of a hollow bottom open container, consisting of a bearing surface and an outer jacket which is vertically exceeded by the supporting plate, and thus creates an elevated edge above it, where in the interior space of the support element there is a symmetrically mounted base , which is in the form of a hollow upper open hull with a higher height than the height of the carrier element. Above the upper edges of the base, anti-vibration washers are mounted on the base surface, and the tensometer sensor is symmetrically inserted inside the base of the base, which can be detachably attached both from below to the supporting surface as well as to the base, the distance between the upper edges of the base and ·· · «anti-vibration washers the difference in the vertical (vertical) dimensions of the tensometer sensor without load and when the load balance is measured in the rigid bodies, the weight is within the range of 1.0 to 1.5 times the maximum weight of the pressure vessel. The battery pack is waterproofly inserted into the battery box and the electronic module is waterproofly inserted into the electronic box. The electronic module is equipped with an implemented wireless communication technology through which it is connected to the central control unit of the control system of this facility and / or to the display device remotely. In a suitable embodiment, the tensometer sensor is at the point of contact with the support surface protruded in the upper mounting bracket, which is located below in the support surface, and at the point of contact with the base, it is counterpropagated in the lower fixing bay located at the bottom of the base. In another suitable embodiment, a wireless communication technology of the type Bluetooth or the type of radio link in the ISM frequency is implemented in the electronic module.

It is also advantageous that the battery box and the electronic box are inserted at the sides of the tensometer sensor, where the battery box is in the form of a hollow upper open square that forms the inner chamber in which the battery pack is inserted, the battery box from the bottom is waterproofly removable attached to the load surface where an opening is made at a point above the battery box which dimensically corresponds to the inner chamber of the battery box and is equipped with doors which are waterproofly closed and have an opening option, which, depending on the dimension and shape, correspond to that opening, and are precisely locked into it in such a way that the bearing surface is not interrupted and where the electronic box is in the form of a hollow, from the lower open square, which creates an inner cavity where the electronic module is stored, the electronic box being detachably attached to the supporting surface, and its inner cavity is provided with a waterproof closing cap from below. In an optimal embodiment, the tensometer sensor with electronic conductors is serial connected to an electronic module, which is then connected to the battery pack, whereby the tensometer sensor, battery box and electronic box together with electric conductors are watered with a waterproof gratings. With a new technical solution, a better effect will be achieved in such a way that the device will be useful for the permanent installation of gas containers in mobile accommodation, and also during driving. It will be able to continuously measure the state of the gas in gas containers with the displayed state of the display device remotely and is currently connected via a central unit with the entire control system ** of this facility, where it is resistant to vibration and water.

An example of a technical solution

The device for measuring the content of pressure vessels is realized as a voltage measuring instrument in rigid bodies 1 wirelessly connected to the central control unit 3 of the undeniable control system of this object, and preferably also to the remote display device 4. The weight measuring instrument in rigid bodies 1 comprises a load bearing an element 11 which is in the form of a hollow cylindrical bottom open cylinder and which consists of an outer casing 115 and a bearing surface 111 which creates the upper 112 and the lower surface 113. In the interior space of the carrier element 11, a base 12 is formed symmetrically in the form of a hollow low , an upper open hull, preferably a prism, where the side walls 121 form the upper edges 122 of the base 12 that almost touch the bearing surface 111 of the support element 11 with its lower surface 113 which is equipped with anti-vibration washers at the point of contact 114, the height of the carrier element 11 is smaller than the height of the base 12. The outer casing 1 15 of the support element 11 extends beyond the vertical upper part 112 of the bearing surface 111 and thus creates an elevated edge 119 above it. The side walls 121 of the base 12 have in their upper section 123 an unlabeled ventilation opening. In the interior space of the base 12, tensometer sensor 13 is symmetrically inserted, the lower ** contact surface 132 snapping into the lower fixing bearing 126, which is formed by a base 12 on the bottom 124, which is disassembled between them, where its upper touch surface 131 it locks into the upper mounting bracket 116 which is composed of the bearing surface 111 in the lower part 113, which is also removably fastened to one another, thereby preventing the possible movement or rotational movement of the tensometer sensor 13 towards the carrier element 11 and / or the base 12.

At the sides of the tensometer sensor 13, there is a battery box 14 and an electronic box 15. In the inner space of the base 12, the battery box 14 is in the form of a hollow upper open square that creates an internal chamber 141 into which the battery pack 142 is inserted. The battery box 14 is from below the waterproofly dismountable attachment to the lower part 113 of the bearing surface 111 where, at a point above the battery box 14, an aperture 117, the dimensions of which correspond to the internal chambers 141, are provided with doors which are waterproofly closed and have a possibility of opening 118 from above, and the shape of the apertures correspond to the openings 117 and clamp into it precisely so that the upper part 112 of the support surface 111 is not disturbed.

The electronic box 15 is in the form of a hollow from the bottom open square, which creates an inner cavity 151 for inserting the electronic module 153 and is dismountably fixed to the lower part 113 of the supporting surface 111 from below, and its inner cavity 151 is waterproofly closed by the cover 152.

Tensometer sensor 13 is coupled with non-repelled waterproof conductors electrically connected to the electronic module 153, which is equipped with an implemented wireless communication technology, with suitable radio transmission in the ISM frequency or Bluetooth technology, and which is also connected to unshielded waterproof electrical conductors, a battery pack 142, as well as through the implemented wireless communication technology to the central control unit 3 of the unmanaged control system of this object. In an appropriate embodiment, the electronic module 153 via the implemented wireless communication technology is also connected to the display device at a distance 4.

Tensometer sensor 13, battery box 14 and electronic box 15 together with ** non-scaled electronic conductors are waterproofed with a non-repelled waterproof gratings.

The distance from the upper edge of the upper edges 122 of the base 12 to the anti-vibration washers 114 corresponds to the difference in the vertical dimension of the tensometer sensor 13 without load and when weighing the balance 1 with a weight within the limits of 1.0 to 1.5 times the maximum weight of the pressure vessel. At this load, the wearing surface 111 touches the upper edges 122 of the base 12 via the washers 114, thereby preventing possible deformation damages of the tensometer sensor 13 with a higher load, while protecting the resilience of the anti-vibration scale 1.

The inner diameter of the carrying surface 111, bounded by the elevated edge 119, corresponds to the diameter of the unpressed pressure vessel mounted on the carrier element 11 of the balance 1, thereby achieving resistance to horizontally acting forces and transverse acceleration.

The total height of the instrument for measuring the voltage in rigid bodies 1 is a maximum of 45 mm.

Industrial use

The device for measuring the content of pressure vessels is used in caravans, motorhomes, etc., for continuous monitoring of the weight of pressure vessels and their fixed attachment while driving the object.
