Description

Technical Field

[0001] This invention relates to a monitoring device for a storage device according to the appended claims, and a storage device including such a monitoring device. Furthermore, this invention relates to a method for installing such a monitoring device according to the appended claims. Background Technology

[0002] Large, elevated storage containers such as silos or hoppers typically require monitoring to ensure proper functioning and adequate access to their contents. By monitoring the weight of the container, an alert can be issued to the user when the weight indicates it's time to refill. Furthermore, weight monitoring can help mitigate uncertainty regarding animal feed availability in the silo, thereby optimizing feed ordering and silo refilling schedules. Various electronic devices have been developed for monitoring the weight of such containers. These devices may include a load cell positioned beneath the container, which monitors the level of contents within the container by measuring its weight.

[0003] A drawback of known monitoring systems for storage devices is the difficulty in retrofitting measuring equipment, such as load cells, to the storage device. Typically, such retrofitting requires heavy machinery, such as cranes, and manual labor to lift the storage device. Therefore, retrofitting storage devices is usually a very complex and expensive undertaking. Furthermore, the stresses generated by the heavy loads and torques applied by the storage device affect the monitoring system and shorten the lifespan of its components, increasing the need for replacement and maintenance.

[0004] Other solutions do not require heavy machinery to lift the storage unit. An example proposed in document US 2020 / 0323169 discloses a system comprising a load unit, a support plate, bolts, an inner leg mount mounted on the load unit, and an outer support. However, this system includes multiple components with complex connections, making it bulky, less stable, and complex to install.

[0005] Document WO 2020 / 024067 discloses a compression load unit and a load unit base support for holding the load unit on the ground. Both the load unit base and the load unit are located inside the support element, which makes the system compact but also complex to install.

[0006] Therefore, uncomplicated monitoring equipment is needed to retrofit existing storage devices. Furthermore, a compact, durable, and reliable storage device is required to withstand heavy loads and pressures. Summary of the Invention

[0007] Despite the existence of known solutions in the field, it is still desirable to develop a monitoring device that overcomes or mitigates at least some of the disadvantages of the prior art.

[0008] Therefore, one object of the present invention is to provide a monitoring device that provides reliable monitoring information, even when subjected to heavy loads and stresses.

[0009] Another objective of this invention is to provide a monitoring device that is not complex and can directly modify an existing storage device.

[0010] Another object of the present invention is to provide a monitoring device that is easy to install and maintain, while providing a compact and space-saving layout.

[0011] Another object of the present invention is to provide a monitoring device that is durable, robust and cost-effective.

[0012] Another object of the present invention is to provide a storage device and a method that achieves high reliability of monitoring while providing simple installation, reduced maintenance requirements, and optimized space utilization.

[0013] These objectives are achieved by the monitoring device, storage device, and method according to the appended claims.

[0014] Therefore, according to one aspect of the invention, a monitoring device for a reservoir having multiple support members is provided. The monitoring device includes: at least one load unit module having a base plate for attachment to a support surface and an elongated measuring device attached to the base plate; and at least one adapter unit configured to attach to a support member of the reservoir and rest on the measuring device; wherein the base plate of the at least one load unit module includes a recess that allows the base plate to at least partially circumferentially surround the support member during installation, and the measuring device is arranged on the base plate such that the measuring device extends at least partially above the recess. The monitoring device can be used to monitor the weight of the reservoir.

[0015] The use of monitoring devices for monitoring storage containers such as silos or hoppers provides the possibility of ensuring proper functioning of the container and adequate access to its contents. For example, in the case of a container containing animal feed, monitoring the container allows the user of the monitoring device to ensure that there is always sufficient feed for the animals. Furthermore, when the supply in the container is insufficient, an alarm can be issued to the user, allowing him / her to refill the container and / or order new feed in a timely manner. In addition, with the aid of monitoring devices such as those disclosed herein, food conversion rate can be monitored in real time. Food conversion rate provides an indication of how many units of animal meat are produced from each unit of animal feed, for example, how many kilograms of chicken meat are produced from one kilogram of chicken feed. Monitoring devices typically include electronic devices, such as load units, which help monitor the operation of the device by recording elastic deformation corresponding to the load from the container or the weight of the container. Based on the load / weight, the level of the contents in the container can be determined. The load unit is typically arranged below the support structure of the container and should be arranged in a stable manner, as the load unit bears the weight of the support structure and thereby supports at least a portion of the container. Therefore, the configuration of the monitoring equipment and the position of the load unit relative to the support structure of the storage device affect the overall stability of the storage device.

[0016] By means of a recess in the base plate of the at least one load unit module that allows the base plate to at least partially circumferentially surround the support member, the monitoring device according to this disclosure provides a stable, compact, and space-saving device. The fact that the base plate at least partially circumferentially surrounds the support member increases the stability of the base plate, and the recess in the base plate means that less material can be used and the base plate covers a smaller area. Furthermore, the measuring device is arranged such that it extends at least partially above the recess, thereby allowing the measuring device to deform under the load of the reservoir. The existing shape of the base plate ensures resistance to tilting and also allows the measuring device to be positioned closer to the center of gravity of the support member without any loss of stability to the reservoir and the monitoring device. Therefore, by means of the recess in the base plate, the fulcrum of the measuring device can be positioned closer to the center of gravity of the support member to which the measuring device is connected. This reduces the stress applied to the measuring device, thereby making the measuring device more durable and longer-lasting. Furthermore, this configuration increases safety by preventing the support members from bending, and it is beneficial because the location of the measuring device mitigates the potential consequences of component failure caused by the high mechanical stress applied to the support members of the reservoir.

[0017] Furthermore, the monitoring device, which includes an elongated measuring device attached to the base plate and an adapter unit configured to be attached to the storage device and resting on the measuring device, provides a robust solution for generating reliable monitoring information, and this solution is easier to modify for existing storage devices.

[0018] The at least one adapter unit can be configured to attach within a cavity of the support member, and the at least one load unit module can be configured to be arranged such that the measuring device extends into the cavity. In this way, the adapter unit is protected within the cavity, and a robust and space-saving monitoring device is achieved.

[0019] The monitoring device may further include at least one load support element configured to be disposed between the at least one adapter unit and the measuring device of the at least one load unit module, wherein the at least one load support element includes a curved surface. The at least one load support element may be disposed on the measuring device, and the at least one load unit module may be configured such that the at least one adapter unit abuts against the curved surface of the load support element during installation. The load support element is configured to compensate for any angular displacement between the load unit module and the adapter unit by means of the curved surface.

[0020] The at least one load unit module may include a sensor device arranged in the measuring device for sensing deformation of the measuring device, the sensor device being operatively connected to the control unit.

[0021] The measuring device and the at least one adapter unit can be configured to be connected to each other by means of fasteners extending through the measuring device and the at least one adapter unit. For connection by means of fasteners, the at least one adapter unit may include a first through-hole having a first diameter, and the measuring device may include a second through-hole having a second diameter, wherein the first diameter is larger than the second diameter. When the monitoring device includes a load support element, the measuring device and the adapter unit of the monitoring device can be configured to be connected to each other by means of fasteners extending through the adapter unit, the load support element, and the measuring device. When the load support element is arranged on the measuring device, the second through-hole having the second diameter can extend through the load support element and the measuring device. When the load support element is arranged on the adapter unit, the first through-hole having the first diameter can extend through the adapter unit and the load support element. The second through-hole in the measuring device is suitably threaded, and therefore the fastener can be rigidly connected to the measuring device by means of the threads. The first diameter of the first through-hole in the adapter unit may be larger than the diameter of the fastener.

[0022] By applying through holes of different sizes in the adapter unit and the measuring device respectively, movement between the components can be achieved when the measuring device deforms. Therefore, this connection configuration between the measuring device and the adapter unit provides a clearance fit between the components, resulting in a more durable connection. Thus, for example, when subjected to heavy loads from the weight of the reservoir and / or vibrations caused by filling or emptying the reservoir, the connection is not at risk of breakage or tearing due to excessive rigidity. The connection between the adapter unit and the measuring device via a load-bearing support element can also be referred to as a bolted connection, which can serve as a support-type joint, thereby allowing movement between the adapter unit rigidly attached to the support member and the measuring device rigidly attached to the base plate. Thus, the monitoring device according to this disclosure not only increases the technical life of the components in the monitoring device but also provides greater installation tolerances.

[0023] The monitoring device may also include at least one spring washer configured to surround a fastener at the at least one adapter unit. The spring washer increases the durability of the connection between the adapter unit and the measuring device by providing vibration resistance while maintaining resistance to rotation of the fastener. Furthermore, arranging the spring washer around the fastener allows for some vertical movement between the adapter unit and the measuring device without compromising the stability of the connection.

[0024] The monitoring device may further include a control unit operably coupled to the at least one load unit module. More specifically, the control unit may be operably coupled to a sensor device of the at least one load unit module. When the monitoring device includes multiple load unit modules, the weight of the storage device will be distributed across all load unit modules. Therefore, the control unit will be configured to receive electrical signals from all load unit modules and determine the total weight of the storage device based on these signals.

[0025] The monitoring equipment may also include a lifting device configured for use during installation at a support member of the storage unit. The lifting device includes a lifting adapter and a lifter. The lifting adapter is configured to attach to the support member, and the lifter is configured to interact with the lifting adapter to lift the support member above the support surface. The lifting device provides favorable assembly / installation conditions, facilitating the retrofitting of currently used storage units. Installation can be completed by a single person using the lifting device. Therefore, it facilitates installation, saving both resources and costs.

[0026] According to another aspect of the invention, a reservoir having a plurality of support members is provided. The reservoir includes a monitoring device as disclosed herein, wherein at least one adapter unit of the monitoring device is attached to a support member of the reservoir, and at least one load unit module is arranged such that a base plate at least partially surrounds the support member and such that the at least one adapter unit rests on a measuring device.

[0027] It should be understood that the monitoring equipment disclosed herein may include multiple load unit modules and adapter units, and suitably, each support member for the storage device to be monitored includes a load unit module and an adapter unit.

[0028] The support member of the reservoir can be shaped to form a cavity into which the adapter unit can be inserted and attached. This cavity can also be referred to as a chamber, space, or opening. For example, the support member can have a generally U-shaped, Ω-shaped, or C-shaped profile or cross-section.

[0029] According to another aspect of the invention, a method is provided for mounting a monitoring device as disclosed herein at a reservoir having a plurality of support members. The method includes: attaching at least one adapter unit to a support member; raising the support member above a support surface; positioning at least one load unit module such that a base plate at least partially surrounds the support member circumferentially; and positioning the support member such that the at least one adapter unit rests on a measuring device of the at least one load unit module. It should be understood that the features and advantages mentioned with respect to the monitoring device disclosed herein are also applicable to this method. The method can be a modification method, and the monitoring device can therefore be mounted at a reservoir already in use. Alternatively, the monitoring device is mounted simultaneously with the reservoir.

[0030] The steps of lifting the support member may include: attaching a lifting adapter to the support member; and lifting the support member above the support surface by means of a lifter that interacts with the lifting adapter.

[0031] The step of positioning at least one load cell module may include positioning the at least one load cell module such that the measuring device extends into a cavity formed by the profile shape of the support member.

[0032] Attaching a lifting adapter may include attaching the lifting adapter to the side of the support member opposite to the adapter unit by using fasteners for attaching the adapter unit.

[0033] The load element module can be a strain gauge module, such as a bending beam load element module. The measuring device of the load element module can therefore be called a bending beam load element. This load element undergoes elastic deformation under stress, thus indicating the weight of the measured entity. The characteristics and functions of the load element are considered common knowledge, and therefore specific details of the measuring device will not be discussed herein. Using the monitoring equipment disclosed herein, the adapter unit is placed on the measuring device of the load element module, and the weight / load of the supporting member / reservoir is thus applied to the measuring device. The measuring device will therefore elastically deform, i.e., bend, under the weight of the reservoir. Therefore, the deformation can correspond to the weight of the reservoir, which can give an indication of the amount of material in the reservoir. The load element module is therefore configured to detect the deformation of the measuring device.

[0034] An elevated storage container with multiple supporting members can be positioned on a concrete slab, platform, or foundation. In other examples, the supporting members of the storage container can rest on a floor in a warehouse, for example, made of a material other than concrete. Therefore, it should be understood that a base plate configured to attach to a supporting surface includes a base plate configured to attach to a concrete base, mounting platform, floor, or any supporting surface for the storage container.

[0035] Other objects, advantages, and novel features of the invention will become apparent to those skilled in the art from the following details and by practicing the invention. Although the invention is described below, it is apparent that the invention may not be limited to the specific details described. Those skilled in the art, upon contact with the teachings herein, will recognize that other applications, modifications, and combinations in other fields are within the scope of the invention.

[0045] Figure 1a and Figure 1b The illustration schematically depicts details of a monitoring device 1 for a storage device according to an example. The storage device can be as follows: Figure 4 The structure is as disclosed herein. Monitoring device 1 includes... Figure 1a and Figure 1b The load unit module 3 shown is included. The load unit module 3 includes a base plate 31 for attachment to a support surface, such as a floor, concrete base, or ground. Figure 1a and Figure 1b The load unit module 3 shown is constructed in a similar manner, but the dimensions of the base plate 31 are different. The load unit module 3 also includes an elongated measuring device 37 attached to the base plate 31. Figure 2a , Figure 2b and Figure 3 As shown, the monitoring device 1 also includes an adapter unit 4, which is configured to attach to a support member of the storage container and rest on the measuring device 37. The support member of the storage container may be... Figures 2a to 5 The type shown is not described, but variations are possible within the scope of the invention. The base plate 31 of the load unit module 3 includes a recess 32 that allows the base plate 31 to at least partially circumferentially surround the support member during installation. A measuring device 37 is arranged on the base plate 31 such that the measuring device 37 extends at least partially above the recess 32 and thus allows the measuring device 37 to deform.

[0046] The load unit module 3 can be a strain gauge module, such as a bending beam load unit module. The measuring device 37 of the load unit module 3 can therefore be referred to as a bending beam load unit. The measuring device 37 can undergo elastic deformation under the load of the supporting member, thereby indicating the weight of the reservoir.

[0047] The recess 32 of the base plate 31 allows the base plate 31 to at least partially surround the support member of the reservoir in the circumferential direction. When installed, the edge of the recess 32 extends at least partially along the circumference / periphery of the support member. The support member, including any support plate associated with it, can have a variety of cross-sectional shapes and sizes, and therefore the recess 32 can be shaped to mate with the cross-section of the support member. In these examples, the recess 32 has a substantially rectangular shape, but it can also have a substantially circular, square, or similar shape. The recess 32 can be formed in the base plate 31 such that the base plate 31 is substantially U-shaped.

[0048] The base plate 31 may include a central portion 33 and two protrusions 35 extending substantially perpendicularly from the central portion 33. The two protrusions 35 may be positioned at opposite ends of the central portion 33. The two protrusions 35 may be configured to extend along a portion of the circumference of the support member. The length of the two protrusions 35 may be adjusted to fit the intended support member. As an example, Figure 1b The protrusion shown is 35 times larger than Figure 1a The protrusions shown extend further from the central portion 33. Although not shown in the figure, these two protrusions 35 can be arranged at an angle relative to the central portion 33 to properly engage with the support member, wherein the angle is greater than 90 degrees. Therefore, the two protrusions 35 can be separated in a direction away from the central portion 33.

[0049] The central portion 33 may include at least one attachment point 34 for attaching the base plate 31 to a support surface on which the reservoir is disposed. The attachment point 34 may be configured as a through-hole in the base plate 31 adapted to receive fasteners, such as screws or bolts. The central portion 33 may include multiple attachment points 34, and in these examples, the central portion 33 includes two attachment points 34. The protrusion 35 may also include at least one attachment point 36, each attachment point 36 for attaching the base plate 31 to the support surface. The attachment point 36 on the protrusion 35 may be configured as a through-hole in the base plate 31 adapted to receive fasteners, such as screws or bolts. Arranging both attachment points 34 and 36 of the base plate 31 in the central portion 33 and the protrusion 35 results in a stable base plate 31 that is securely attached to the support surface and prevented from tilting.

[0050] An elongated measuring device 37 is arranged on the base plate 31 such that it extends above the recess 32. The recess 32 allows the measuring device 37 to deform / bend downwards due to a load applied to it without contacting the base plate 31 or the ground. Typically, the measuring device 37 is attached to the central portion 33 of the base plate 31. Therefore, the measuring device 37 can extend parallel to the protrusion 35 of the base plate 31.

[0051] The load unit module 3 of the monitoring device 1 also includes a sensor device 38, which is arranged in the measuring device 37 for sensing the deformation of the measuring device 37. The sensor device 38 is operatively connected to the control unit (71, see...) Figure 3 Sensor device 38 may include a strain gauge or the like. Sensor device 38 may be configured to convert detected deformation into an electrical signal and transmit the electrical signal to control unit 71. Sensor device 38 may include a transmitter or be electrically connected to a transmitter to transmit data to control unit 71.

[0052] The monitoring device 1 may also include a load support element 5 configured to be disposed between the measuring device 37 and the adapter unit 4. (Refer to...) Figure 2b The load support element 5 is described further.

[0053] Figures 2a to 2b The front view and cross-sectional view of the monitoring device 1 according to the example are schematically illustrated, respectively. In these figures, the monitoring device 1 is mounted on the support member 21 of the storage container. Figure 2a An adapter unit 4 of the monitoring device 1 is shown, which is attached to the support member 21 within a cavity 23 formed by the contour shape of the support member 21. Thus, the load unit module 3 is arranged such that the measuring device 37 extends into the cavity 23. The cavity 23 may also be referred to as a chamber, space, or opening. The support member 21 may include a rear wall 22 and two side walls 24 extending away from the rear wall 22. The side walls 24 may form a short end of the support member 21, and the rear wall 22 may form a long end of the support member 21; alternatively, the side walls 24 may form a long end of the support member 21, and the rear wall 22 may form a short end of the support member 21. The cavity 23 is formed between the rear wall 22 and the side walls 24. In this example, the adapter unit 4 of the monitoring device 1 is attached to the rear wall 22 of the support member 21 within the cavity 23.

[0054] The recess 32 of the base plate 31 is adapted to the shape of the support plate 25 of the support member 21. The load unit module 3 of the monitoring device 1 is arranged such that the central portion 33 of the base plate 31 extends along the opening of the cavity 23 and the two protrusions 35 of the base plate 31 extend at least partially along the side wall 24 of the support member 21.

[0055] like Figure 2a As shown, the adapter unit 4 may include a bracket 41. The bracket 41 may be L-shaped and include two legs 42, 44 arranged substantially perpendicular to each other. These two legs may be referred to as the vertical leg 42 and the horizontal leg 44. The vertical leg 42 of the bracket 41 is attached to the rear wall 22 of the support member 21. The horizontal leg 44 extends substantially parallel to the ground or floor surface and is connected to the measuring device 37. The horizontal leg 44 may be shorter than the vertical leg 42. The vertical leg 42 of the bracket 41 includes at least one attachment point 43 or aperture for attachment to the support member 21 by means of a fastener. The horizontal leg 44 of the bracket 41 includes at least one attachment point 45 for attachment to the measuring device 37 by means of a fastener 8. The attachment points 43, 45 may be through holes.

[0056] The support 41 may also include two parallel sidewalls 46 connected to the vertical leg 42 and the horizontal leg 44. The sidewalls 46 may extend substantially perpendicular to the vertical leg 42 and the horizontal leg 44. The sidewalls 46 may be substantially triangular in shape, such that the sidewalls 46 taper along the length of the vertical leg 42 in the direction of the horizontal leg 44.

[0057] The measuring device 37 of the load unit module 3 can be attached to the base plate 31 at one end and extend to the cavity 23 formed by the contour shape of the support member 21 at the other end. In this way, the measuring device 37 is connected to the adapter unit 4 in the cavity 23.

[0058] like Figure 2a As shown, the load unit module 3 may also include a ground wire 39, which may also be referred to as a ground cable, grounding wire, grounding wire, grounding cable, etc. The ground wire 39 may be arranged to connect the base plate 31 and the adapter unit 4. The ground wire 39 is configured to transfer electricity from the storage structure to the ground.

[0059] like Figure 2b As shown, the adapter unit 4 can be attached to the support member 21 by means of fasteners such as screws or bolts. The fasteners can be inserted into one or more attachment points 43 of the adapter unit 4 and pass through the rear wall 22 of the support member 21. The monitoring device 1 may also include a back plate 47 configured to be arranged on the side of the support member 21 opposite to the adapter unit 4. Thus, the fasteners can extend through the adapter unit 4, the rear wall 22 of the support member 21, and the back plate 47. The back plate 47 can serve as a reinforcement for the rear wall 22 of the support member 21, thereby strengthening the connection between the adapter unit 4 and the support member 21. The back plate 47 can also provide structural stability because the back plate 47 attached to the rear wall 22 adds stiffness to the support member 21.

[0060] like Figure 2bAs shown, the monitoring device 1 may further include a load support element 5 configured to be disposed between the measuring device 37 of the load unit module 3 and the adapter unit 4. The load support element 5 includes a curved surface 51. The load support element 5 is configured to compensate for any angular displacement between the load unit module 3 and the adapter unit 4 by means of the curved surface 51. The load support element 5 may be substantially hemispherical or spherical.

[0061] In this example, the load support element 5 is arranged on the measuring device 37, and the load unit module 3 is arranged such that the adapter unit 4 abuts against the curved surface 51 of the load support element 5. However, it should be understood that the load support element 5 can be attached to the adapter unit 4, and the curved surface 51 of the load support element 5 can abut against the measuring device 37.

[0062] like Figure 2b As shown, the measuring device 37 and the adapter unit 4 of the monitoring device 1 can be connected to each other by means of a fastener 8 extending through the adapter unit 4, the load support element 5, and the measuring device 37. For this purpose, the adapter unit 4 may include a first through-hole 61 at an attachment point 45 in the horizontal leg 44 of the bracket 41. The first through-hole 61 may have a first diameter. The load support element 5 and the measuring device 37 may include a second through-hole 62 having a second diameter, wherein the first diameter is larger than the second diameter. The first through-hole 61, with a diameter larger than the second through-hole 62, allows movement between the adapter unit 4 and the measuring device 37. The connection between the adapter unit 4, the load support element 5, and the measuring device 37 restricts lateral movement of these components relative to each other by the shank of the fastener 8 supported on the sides of the through-holes 61, 62. However, the gap between the fastener 8 and the first through-hole 61 in the adapter unit 4 allows some lateral movement to occur.

[0063] The monitoring device 1 may also include a spring washer 9 configured to surround the fastener 8 that connects the adapter unit 4 and the measuring device 37. The spring washer 9 may also be referred to as a split-lock washer. The spring washer 9 is arranged around the fastener 8 at the adapter unit 4. The spring washer 9 provides vibration resistance while maintaining resistance to rotation of the fastener 8. Furthermore, the arrangement of the spring washer 9 around the fastener 8 allows for some vertical movement between the adapter unit 4 and the measuring device 37 without compromising the stability of the connection.

[0064] Figure 3 A monitoring device 1 for a storage device 2 is schematically illustrated according to an example. The monitoring device 1 can be as follows: Figure 1a , Figure 1b , Figure 2a or Figure 2bThe device is constructed as disclosed herein, and the monitoring device 1 also includes a control unit 71, which is operatively connected to the load unit module 3.

[0065] The control unit 71 can be configured to receive an electrical signal corresponding to the elastic deformation of the measuring device 37 from the sensor device 38 of the load unit module 3 and determine the current weight of the storage device based on the electrical signal. The determined weight of the storage device can be stored in the memory of the control unit 71 or in an external memory. The control unit 71 can also be configured to estimate the volume of the contents in the storage device based on the determined weight of the storage device. The control unit 71 or the monitoring device 1 may include a data processing unit. The control unit 71 can be configured to send the determined weight or volume of the contents in the storage device to a second control unit, to a node in a communication network such as a cloud or server, and / or to a user device associated with the user monitoring the storage device using the monitoring device 1, such as a computer, smartphone, tablet, etc.

[0066] The control unit 71 can also be configured to perform appropriate actions based on the determined weight. Appropriate actions may include controlling the flow from the reservoir, ordering more feed, or similar actions. According to an example, the control unit 71 can be configured to provide an alarm based on the determined weight, enabling the operator to perform appropriate actions. The alarm or warning can be provided audibly and / or visually. The alarm or warning may be displayed on a monitor. The alarm or warning may be sent to a control center and / or to an operator center for the reservoir.

[0067] Figure 4 A storage container 2 with multiple support members 21 is schematically illustrated according to an example. Only a portion of the storage container 2 is shown in the figure. The storage container 2 can be a silo, tank, hopper, or any other type of storage container 2, which rests on the support members 21. The storage container 2 can be used to store and distribute particles or liquids, such as grains, sand, pellets, or milk, wine, oil, etc. The support members 21 can also be referred to as legs. The weight of the storage container 2 is distributed on the support members 21. Depending on the configuration and placement of the storage container 2, the storage container 2 can have at least two support members 21. The support members 21 of the storage container 2 can be as follows: Figure 2a The structure is as disclosed in the document.

[0068] Storage 2 includes, for example Figure 1a , Figure 1b , Figure 2a , Figure 2b or Figure 3The monitoring device 1 disclosed herein. In this example, the monitoring device 1 includes four load unit modules 3 and four adapter units 4, with one load unit module 3 and one adapter unit 4 at each support member 21 of the storage unit 2. The adapter unit 4 is attached to the corresponding support member 21, and the load unit module 3 is arranged such that the base plate 31 at least partially surrounds the support member 21 circumferentially and the adapter unit 4 rests on the measuring device 37.

[0069] Figure 5 A monitoring device 1 for a reservoir 2 having multiple support members 21 is schematically illustrated according to an example. The monitoring device 1 can be as follows: Figure 1a , Figure 1b , Figure 2a , Figure 2b or Figure 3 The device is constructed as disclosed herein, and the monitoring device 1 also includes a lifting device 11 configured for use during installation at the support member 21 of the storage device 2.

[0070] The lifting device 11 includes a lifting adapter 12 and a lifter 13. The lifting adapter 12 is configured to attach to the support member 21, and the lifter 13 is configured to interact with the lifting adapter 12 to lift the support member 21 above the support surface during installation of the load unit module 3. The lifting adapter 12 may include an L-shaped bracket 14, which includes two legs 15, 16 arranged at a substantially 90-degree angle. These two legs 15, 16 may be referred to as a vertical leg 15 and a horizontal leg 16. The vertical leg 15 is attached to the support member 21. Specifically, the vertical leg 15 is attached to the rear wall 22 of the support member 21. Therefore, the vertical leg 15 may include a plurality of attachment points 17 or orifices for attachment to the support member 21 by means of fasteners.

[0071] The lifting adapter 12 can be configured to attach to the side of the support member 21 opposite to the adapter unit 4. The lifting adapter 12 can be attached to the support member 21 such that it abuts against the backplate 47 of the monitoring device. The lifting adapter 12 can be configured to be attached to the support member 21 using at least one of the fasteners used to attach the adapter unit 4 to the support member 21. The fasteners attaching the adapter unit 4 to the support member 21 can protrude through the support member 21 on the opposite side of the rear wall 22. Therefore, the lifting adapter 12 can be mounted on the fasteners protruding through the rear wall 22 and can be secured by means of end nuts on the fasteners. The lifting adapter 12 may also include two parallel sidewalls 18 connected to the vertical leg 15 and the horizontal leg 16. The sidewalls 18 can extend substantially perpendicular to the vertical leg 15 and the horizontal leg 16. The sidewalls 18 can be substantially triangular in shape, such that they taper from the direction of the horizontal leg 16 along the length of the vertical leg 15. Each of the sidewalls 18 may include a hollow section.

[0072] The lifter 13 can be any suitable lifting device, such as a mechanical, hydraulic, or pneumatic jack. The lifter 13 is configured to interact with the lifting adapter 12 to lift the support member 21 above the ground. More specifically, the lifter 13 can be configured to interact with the horizontal outriggers 16 of the L-shaped support 14 of the lifting adapter 12.

[0073] The monitoring device 1 may also include a template drill plate, which can be used to mark the attachment points of the adapter unit 4 on the support member 21. Such a template drill plate or drill guide (not shown) indicating proper drilling positioning may be provided to the installer as part of the monitoring device 1 to facilitate the installation of fasteners and ensure their proper positioning. The monitoring device 1 may also include any suitable fastening devices, such as screws, bolts, and nuts, used during the installation of the different components of the monitoring device 1.

[0074] Figure 6 A flowchart illustrating a method for mounting monitoring device 1 on support member 21 of storage device 2, according to an example, is shown. Monitoring device 1 can be mounted as follows: Figure 1a , Figure 1b , Figure 2a , Figure 2b , Figure 3 or Figure 5 Constructed as disclosed herein. This method can be achieved by using, as... Figure 5The lifting device 11 shown is used to perform this. The method includes: attaching at least one adapter unit 4 to the support member 21 s101; lifting the support member 21 above the support surface 100 s102; positioning at least one load unit module 3 s103 such that the base plate 31 at least partially surrounds the support member 21 circumferentially; and positioning the support member 21 s104 such that the at least one adapter unit 4 rests on the measuring device 37 of the load unit module 3. In this way, the monitoring device 1 disclosed herein can be easily installed at the storage unit 2 without the need for expensive equipment such as lifting cranes. This method can be a modification method, and therefore the monitoring device 1 can be installed at a storage unit 2 that is already in use. Advantageously, the load unit module 3 and the adapter unit 4 are installed at each support member 21 of the storage unit 2, and therefore the method is repeated for each support member 21. The load unit module 3 and the adapter unit 4 can be installed sequentially, one after another, for example in a clockwise direction at each support member 21.

[0075] Attaching the adapter unit 4 to the support member 21 may include drilling multiple holes in the support member 21 and attaching the adapter unit 4 by means of fasteners arranged through these holes. The adapter unit 4 may be attached to the support member 21 at a predetermined height such that when the monitoring device 1 is installed, the adapter unit 4 can rest on the measuring device 37. Therefore, attaching the adapter unit 4 to the support member 21 at a predetermined height ensures that when the adapter unit 4 rests on the measuring device 37, the support member 21 does not contact the support surface 100.

[0076] The step of attaching the adapter unit 4 to the support member 21 may include using a template drilling plate that indicates where holes should be drilled on the support member 21 for attaching the adapter unit 4.

[0077] The step of attaching the adapter unit 4 to the support member 21 may include: arranging the adapter unit 4 on a first side of the support member 21 and arranging the back plate 47 on the opposite side of the support member 21, and attaching the adapter unit 4, the support member 21, and the back plate 47 by means of fasteners extending through the adapter unit 4, the support member 21, and the back plate 47. In one example, attaching the adapter unit 4 to the support member 21 includes arranging the adapter unit 4 in a cavity 23 formed by the contour shape of the support member 21.

[0078] The step of lifting the support member 21 s102 may include: attaching the lifting adapter 12 to the support member 21; and lifting the support member 21 above the ground by means of a lifter 13 that interacts with the lifting adapter 12. Therefore, lifting the support member 21 s102 may include: arranging the lifter 13 below the lifting adapter 12 and operating the lifter 13 such that the lifter 13 abuts against the lifting adapter 12 and ultimately lifts the support member 21 from the ground. The lifter 13 thus applies a lifting force to the lifting adapter 12. By using this lifting device 11, the installation of the monitoring device 1 can be completed by one person without the need for a lifting crane or other expensive equipment. Attaching the lifting adapter 12 to the support member 21 may include temporarily attaching the lifting adapter 12. Therefore, the lifting adapter 12 can be removably attached to the support member 21. In this way, the same lifting adapter 12 can be used to install multiple load unit modules 3 and adapter units 4 on all the support members 21 of the storage unit 2.

[0079] The step of lifting the support member 21 s102 may include attaching the lifting adapter 12 to the side of the support member 21 opposite to the adapter unit 4 by using fasteners for attaching the adapter unit 4. Thus, the lifting adapter 12 and the adapter unit 4 are attached to the support member 21 by means of at least one common fastener. This eliminates the need for a separate attachment device for the lifting adapter 12 and facilitates the installation of the monitoring device 1. By using the same fasteners to attach the adapter unit 4 and the lifting adapter 12 to opposite sides of the support member 21, the number of through holes required in the support member 21 can be reduced. Therefore, a robust and easy-to-install lifting device 11 is achieved.

[0080] When performing this method to retrofit the monitoring device 1 at the storage container 2, the step of lifting the support member 21 s102 may further include removing the support member 21 from the support surface 100 before lifting it. Therefore, if the storage container 2 is positioned on the platform and the support members 21 are attached to the platform by means of fasteners, each support member 21 should be removed from the platform before attempting to lift it. The support member 21 can be removed from the support surface by unscrewing the fasteners or by cutting the fasteners, so that the support member 21 is no longer attached.

[0081] Positioning the load unit module 3 s103 such that the base plate 31 at least partially surrounds the support member 21 may include positioning the load unit module 3 such that at least a portion of the measuring device 37 is arranged below and aligned with the adapter unit 4 on the support member 21.

[0082] The step of positioning the support member 21 in position s104 such that the adapter unit 4 rests on the measuring device 37 of the load unit module 3 may include lowering the support member 21 by means of the lifter 13. Once the support member 21 has been positioned such that it rests on the measuring device 37, the lifter 13 can be removed from below the lifting adapter 12, and the lifting adapter 12 can be removed / disassembled from the support member 21. The lifter 13 and the lifting adapter 12 can then be used on another support member 21 to mount another load unit module 3.

[0083] The step of positioning the load unit module 3 s103 may include positioning the load unit module 3 such that the measuring device 37 extends into the cavity 23 formed by the contour shape of the support member 21. When the adapter unit 4 is attached to the support member 21 within the cavity 23, the load unit module 3 should be positioned such that the measuring device 37 extends into the cavity 23, allowing the adapter unit 4 to rest on the measuring device 37. Furthermore, when the monitoring device 1 includes a load support element 5, the load unit module 3 having the load support element 5 should be positioned such that the load support element 5 is arranged below and aligned with the adapter unit 4 on the support member 21. The step of positioning the support member 21 s104 such that the adapter unit 4 rests on the measuring device 37 of the load unit module 3 may include positioning the support member 21 such that the support member 21 abuts against the load support element 5. The step of positioning the load unit module 3 s103 may include positioning the load unit module 3 such that the load support element 5 is arranged between the adapter unit 4 and the measuring device 37.

[0084] Figure 7 A monitoring device 1 for a storage device 2 is schematically illustrated according to an example. The monitoring device 1 can be as follows: Figure 1a , Figure 1b , Figure 2a , Figure 2b , Figure 3 or Figure 5 The structure is as disclosed in the document. Therefore, the monitoring device 1 includes a load unit module 3 having a base plate 31 and an elongated measuring device 37 attached to the base plate 31. The load unit module 3 of the monitoring device 1 also includes a sensor device 38 arranged in the measuring device 37 for sensing deformation of the measuring device 37. The monitoring device 1 also includes at least one adapter unit 4 configured to attach to the support member 21 of the storage unit 2 and rest on the measuring device 37.

[0085] The figure illustrates a monitoring device 1 including a cable 300, which is used to operatively connect a measuring device 37 to a control device 71, for example... Figure 3 As disclosed in the figure, cable 300 can be arranged to connect measuring device 37 to junction box (not shown), which is in turn operatively connected to control device 71. Thus, sensor device 38 of measuring device 37 can be operatively connected to control device 71 via junction box arranged at storage unit 2. It should be understood that monitoring device 1, as illustrated in the previous figures, typically also includes cable 300, although cable 300 is not shown in the figures. Cable 300 protrudes from measuring device 37 at connection point 370. Connection point 370 is located at the short end of measuring device 37 and thus away from support member 21 and adapter unit 4. Therefore, a portion of cable 300 protrudes away from base plate 31 (beyond base plate 31) before bending towards and onto base plate 31. With this arrangement of cable 300, there is a risk that cable 300 may be damaged, and data transmission from measuring device 37 to control device 71 may be disrupted as a result.

[0086] Therefore, the monitoring device 1 includes a cable protector 310. The cable protector 310 may include a bent metal plate and can be connected to the measuring device 37 to hold it in place. The cable protector 310 can be connected to the measuring device 37 using the same fasteners used to connect the measuring device 37 to the base plate 31. Therefore, the cable protector 310 may have a C-shaped or U-shaped form, with one leg connected to the measuring device 37 and the other leg resting on a support surface 100 adjacent to the base plate 31. Thus, the cable protector 310 is configured to at least surround the protruding portion of the cable 300 and protect it from physical impact / damage. The cable 300 can also be connected to the base plate 31 by means of a cable retainer 320. It should be noted that although the cable 300 is illustrated as terminating in a straight line with the recess 32 of the base plate 31, the cable 300 is actually quite long and typically connects to a junction box.

[0087] Figure 8 A monitoring device 1 for a storage device 2 is schematically illustrated according to an example. The monitoring device 1 can be as follows: Figure 1a , Figure 1b , Figure 2a , Figure 2b , Figure 3 or Figure 5 The device is constructed as disclosed herein. In this example, the monitoring device 1 includes a cable 300 for operatively connecting the measuring device 37 to the control device 71, as shown in the diagram. Figure 3As disclosed herein. The cable 300 can be arranged to connect the measuring device 37 to a junction box (not shown), which is in turn operatively connected to the control device 71. Thus, the sensor device 38 of the measuring device 37 can be operatively connected to the control device 71 via the junction box located at the storage container 2. The cable 300 protrudes from the measuring device 37 at a connection point 370. Here, the connection point 370 is located on the long side of the elongated measuring device 37. Therefore, the cable 300 protrudes away from the long side of the measuring device 37, appropriately crossing the base plate 31 or the recess 32 of the base plate 31, and then bends upward along the support member 21 of the storage container 2. With this configuration in which the cable 300 protrudes from the measuring device 37 closer to the support member 21, the cable 300 will not protrude beyond the base plate 31, and the cable 300 will be less likely to be damaged. This achieves a safe and reliable connection between the measuring device 37 and the control device 71.
