Description

Technical Field

[0001] The present application belongs to the technical field of weighing instruments, and specifically relates to an anti-cheating weighing instrument device and an installation method thereof. Background Art

[0002] A scale uses the force of gravity acting on an object to convert its weight into an electrical signal proportional to it, thereby determining its mass. Electronic scales have become a crucial tool for automated weighing control and trade measurement, essential for modern development, and the primary weighing equipment used by factories, mines, and businesses for bulk cargo measurement. They are also crucial for businesses' external business settlements.

[0003] As metallurgical enterprises expand, the complexity and technical requirements of material measurement management continue to increase. Traditional material measurement management models suffer from issues such as dispersed weighing locations, ineffective vehicle control, low operational efficiency, and slow data transfer. Furthermore, with the advancement of automation and information technology, on-site measurement personnel have decreased, and measurement fraud has increased, leading to significant material losses in enterprises.

[0004] Existing technical solutions primarily include ground scales and deep pit in-ground scales. Ground scales have the disadvantage of exposed primary components, making them susceptible to damage and interference, and require the construction of longer approach roads, resulting in high civil engineering costs. Deep pit in-ground scales, while having their primary components located underground, are less susceptible to fraud, but they require a larger civil engineering component, increasing costs. Furthermore, the surface of the equipment is flush with the ground, which can lead to edge-pressing fraud during vehicle measurement. Summary of the Invention

[0013] In some embodiments, the bladder-type protective structure includes at least one protective surface, and the scale body is connected to the protective surface of the bladder-type protective structure.

[0014] In some embodiments, the bag-type protective structure includes two protective surfaces, and the two protective surfaces are respectively in contact with the balance body and the civil foundation.

[0015] In some embodiments, the side of the bladder-type protective structure facing away from the balance body is arc-shaped.

[0016] In some embodiments, the bladder-like protective structure protrudes out of the covering portion.

[0017] The technical solution adopted to achieve the purpose of this application is that, in the second aspect of this application, the present invention further discloses a method for installing the anti-cheating weighing device based on the first aspect, comprising the following steps:

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0035] The embodiment of the present invention discloses an anti-cheating weighing device, which can solve the technical problem of material measurement cheating existing in ground scales and deep pit underground scales, thereby improving management timeliness and data security and avoiding corruption risks.

[0036] The technical solution of this application is described in detail below through specific embodiments:

[0037] See Figure 1 and Figure 2 In a first embodiment of the present application, an anti-cheating weighing device is disclosed, comprising a support base 100, a sensor pre-embedded structure 200, a measuring element sensor 300, a weighing body 400, and a bladder-type protective structure 500. The sensor pre-embedded structure 200 is mounted on the support base 100, which is in turn mounted on the support base 100. The weighing body 400 is mounted above the measuring element sensor 300, and the bladder-type protective structure 500 is disposed around the weighing body 400.

[0038] The measuring element sensor 300 of the anti-cheating weighing device disclosed in this embodiment is located in a shallow foundation pit 610, making it difficult for unauthorized personnel to directly access the measuring element sensor 300, thereby preventing tampering with the measuring element sensor 300 or the installation of a wireless remote control device. Furthermore, the design of the bladder-like protective structure 500 not only creates a physical isolation layer, preventing damage to the measuring element sensor 300 or the installation of cheating devices, but also prevents the scale 400 from becoming stuck due to dropped foreign objects, thereby ensuring the accuracy of measurement data.

[0039] Compared to traditional deep pits (depth > 1.5m), this device's shallow foundation pit 610 is ≤ 50cm deep, reducing earthwork by approximately 65% ​​and concrete usage by 70%. The cover 420 of the scale body 400 extends beyond the shallow foundation pit 610, allowing vehicles to fully access the scale without requiring a long approach road. This shortens the approach road by 40%-60%, directly reducing road hardening and land occupation costs.

[0040] The anti-cheating weighing device disclosed in this embodiment achieves the triple goals of preventing cheating, reducing costs, and improving accuracy through structural innovation (capsule-type protective structure 500 + shallow foundation pit 610) and data fusion (pressure distribution monitoring). It is particularly suitable for unattended measurement scenarios in industries such as metallurgy and energy, and has significant economic benefits and social value.

[0041] In one embodiment, the scale 400 includes a connecting portion 410 and a covering portion 420 . The connecting portion 410 is connected to the measuring element sensor 300 . The covering portion 420 is located on a side of the connecting portion 410 facing away from the measuring element sensor 300 , and the area of ​​the covering portion 420 is larger than that of the connecting portion 410 .

[0042] On the one hand, the extended cover 420 effectively prevents foreign matter from falling into the gap between the connecting portion 410 and the shallow foundation pit 610, thereby preventing the scale 400 from getting stuck and ensuring the accuracy of the measured data. On the other hand, the extended cover 420 can guide rain and snow, preventing them from entering the shallow foundation pit 610 directly through the gap between the connecting portion 410 and the shallow foundation pit 610, thereby reducing maintenance difficulties.

[0043] In one embodiment, a guide groove (slope ≥ 15°) is provided at the connection between the connecting portion 410 and the covering portion 420. The guide groove can guide foreign objects such as rain, snow, or gravel more quickly, thereby preventing these foreign objects from accumulating in large quantities on the scale body 400.

[0044] In one embodiment, a pressure sensor is provided within the bladder-type protective structure 500 .

[0045] The covering portion 420 is larger than the connecting portion 410 (a recommended difference of 30% or greater), forming an "outward-expanding load-bearing platform." When a vehicle tire attempts to press against its edge, pressure sensors at the edge of the covering portion 420 detect abnormal pressure distribution (via the pressure array integrated into the bladder-type protective structure 500), and the system immediately identifies cheating behavior.

[0046] In one embodiment, the bladder-type protective structure 500 includes at least one protective surface, and the scale body 400 is connected to the protective surface of the bladder-type protective structure 500 .

[0047] The design of the connection surface can make the connection between the bag-type protective structure 500 and the scale body 400 more firmly, thereby making it more difficult for illegal personnel to pry open the bag-type protective structure 500 and reducing the possibility of the bag-type protective structure 500 being pried open.

[0048] In one embodiment, the connecting portion 410 utilizes a composite "wave-flat" structure, providing multi-point support on the contact surface of the scale body 400. When a vehicle is mounted on the scale, the air pressure within the bladder automatically adjusts (perhaps with an integrated micro-pump, for example), ensuring a gap of 0.5 mm or less between the protective surface and the scale body 400, completely preventing the insertion of cheating tools such as wires and hooks.

[0049] In one embodiment, the bag-type protective structure 500 includes two protective surfaces, which are respectively in contact with the scale body 400 and the civil foundation 600 .

[0050] When the bag-type protective structure 500 has two protective surfaces, its side protective surfaces are connected to the scale body 400, and its bottom protective surface is connected to the civil engineering foundation 600. When the bag-type protective structure 500 has only one protective surface, that protective surface can be directly connected to the side wall of the connecting portion 410. When the bag-type protective structure 500 has three protective surfaces, its top protective surface can be connected to the bottom wall of the covering portion 420, its side protective surfaces can be connected to the side wall of the connecting portion 410, and its bottom protective surface can be connected to the civil engineering foundation 600.

[0051] In one embodiment, the side of the bladder-type protective structure 500 facing away from the balance body 400 is arc-shaped.

[0052] The curved surface distributes concentrated loads over a larger area, reducing the maximum stress by 40%. Compared with flat structures, it has better impact resistance.

[0053] A matte texture coating can also be sprayed on the curved surface to form a diffuse reflection with the surrounding environment, reducing the accuracy of cheaters in judging the sensor position through light and shadow.

[0054] In one embodiment, the curvature radius R of the side of the bladder-type protective structure 500 is 300 mm. This allows the bladder-type protective structure 500 to have a larger curvature on the side facing away from the balance body 400, increasing the elasticity of the bladder-type protective structure 500 and enabling it to better adapt to the shape changes and slight deformations of the balance body 400 under different working conditions.

[0055] In one embodiment, the bladder-type protective structure 500 protrudes beyond the covering portion 420. This expands the coverage of the bladder-type protective structure 500. The protruding portion of the bladder-type protective structure 500 can more effectively protect the scale body from external impact, foreign object intrusion, and environmental factors (such as rain and dust). The expanded coverage helps reduce the risk of damage to the scale body and improves the durability and lifespan of the equipment.

[0056] In one embodiment, the bladder-type protective structure 500 is made of rubber. The rubber bladder has elastic properties and does not affect the measurement accuracy while providing effective protection.

[0057] In one embodiment, the cross section of the bladder-type protective structure 500 located on one side of the scale body 400 is semicircular, and the cross section of the bladder-type protective structure 500 located on the other side of the scale body 400 is triangular.

[0058] The bladder-type protective structure 500 features different cross-sectional shapes on both sides of the scale body 400, allowing it to adapt to different operating conditions and stresses. A semicircular cross-section is suitable for applications requiring better adaptation to the shape and deformation of the scale body 400, while a triangular cross-section is suitable for applications requiring greater stability and strength. This design enhances the flexibility and durability of the device.

[0059] Through the above embodiments, the present application has at least the following beneficial effects or advantages: the anti-cheating weighing device disclosed in the present application effectively solves the cheating risks and high construction costs of traditional weighing equipment through the collaborative innovation of the shallow foundation pit 610, the capsule-type protective structure 500 and the extended design of the weighing body 400, significantly improves the safety, accuracy and economic benefits of the measurement system, and provides key technical support for intelligent measurement in the metallurgical industry.

[0060] See Figure 3 Based on the same inventive concept, a second embodiment of the present application discloses a control method for an anti-cheating weighing device based on any embodiment of the first aspect, which comprises the following steps:

[0061] S1: A shallow foundation pit 610 is reserved in the civil foundation 600;

[0062] S2: The support base 100, the sensor embedded structure 200, and the measuring element sensor 300 are embedded in the shallow foundation pit 610 in sequence, and then the scale body 400 is covered on the measuring element sensor 300, and the scale body 400 is higher than the surface of the civil engineering foundation 600;

[0063] S3: Arrange a bag-type protective structure 500 around the scale body 400 to close the gap between the scale body 400 and the shallow foundation pit 610.

[0064] The control method of the anti-cheating weighing device disclosed in this embodiment makes the foundation of the entire weighing device more stable by reserving a shallow foundation pit 610 in the civil engineering foundation 600, and pre-buries the support base 100, the sensor pre-buried structure 200 and the measuring element sensor 300 in the shallow foundation pit 610 in sequence. The weighing body 400 is higher than the surface of the civil engineering foundation 600, which reduces the area of ​​direct contact with the ground, helps to prevent the impact of ground settlement or deformation on the weighing device, and improves the durability of the equipment. A bladder-type protective structure 500 is arranged around the weighing body 400 to close the gap between the weighing body 400 and the shallow foundation pit 610. This design effectively prevents illegal personnel from cheating or interfering with the measuring element sensor 300 through the gap, thereby improving the anti-cheating ability of the equipment. The bladder-type protective structure 500 has elastic properties and can adapt to the shape and deformation of the weighing body 400 while maintaining a close fit with the weighing body 400, further enhancing the anti-cheating effect.

[0065] The bladder-type protective structure 500 is also relatively simple to deploy, requiring only a closed perimeter around the scale body 400, making it easy to maintain and inspect. If repairs or component replacements are required, the bladder-type protective structure 500 can be opened, reducing maintenance effort and costs. Compared to traditional deep pit underground scale installation methods, this method eliminates the need for large-scale civil engineering work, thereby reducing construction costs.

[0066] In one embodiment, the bottom of the connecting portion 410 is located inside the shallow foundation pit 610 , and the top of the connecting portion 410 is located outside the shallow foundation pit 610 .

[0067] The connecting portion 410 serves as a transitional structure between the shallow foundation pit 610 and the ground, providing important support and fixation. Its bottom lies within the shallow foundation pit 610, completely enclosing the measuring element sensor 300, thereby reducing the risk of fraud. Its top lies outside the shallow foundation pit 610, allowing the scale 400 to move up and down. This structure also ensures that the covering portion 420 is elevated above the foundation 600, preventing edge compression during vehicle measurement.

[0068] The presence of the connecting portion 410 makes the gap between the shallow foundation pit 610 and the ground or the scale body 400 smaller, which helps prevent external substances such as dust and moisture from entering the interior of the scale.

[0069] In one embodiment, the area of ​​the connecting portion 410 is smaller than the area of ​​the shallow foundation pit 610, allowing more space for adjustment and fixation of the connecting portion 410 within the shallow foundation pit 610. This facilitates equipment installation and allows the connecting portion 410 to more accurately connect with the support base 100, sensor embedded structure 200, and other components within the shallow foundation pit 610, thereby improving installation efficiency and accuracy.

[0070] The area of ​​cover 420 is larger than that of shallow pit 610, allowing it to completely cover shallow pit 610 and provide additional protection. This helps prevent foreign matter (such as rainwater and dust) from entering shallow pit 610, protecting delicate components such as internal sensors from contamination and corrosion. Furthermore, the extended portion of cover 420 serves as an anti-cheating measure, preventing unauthorized individuals from cheating or interfering through the gap between cover 420 and shallow pit 610.

[0071] The area of ​​the cover 420 is larger than that of the shallow foundation pit 610, allowing it to extend outward, creating a larger support surface. This design helps disperse external shock and vibration, improving the structural stability of the equipment. Especially in large-scale equipment, the extended portion of the cover 420 can serve as an additional support point, enhancing the overall stability of the equipment.

[0072] The design of connecting portion 410 being smaller than shallow pit 610 and covering portion 420 being larger optimizes space utilization. Connecting portion 410 only occupies a portion of the space within shallow pit 610, leaving more room for the installation and securing of other components. The extended portion of covering portion 420 fully utilizes the space outside shallow pit 610, providing greater coverage and protection.

[0073] In one embodiment, the bladder-type protective structure 500 located on one side of the scale body 400 has a semicircular cross-section. This allows it to better adapt to the shape and deformation of the scale body 400, resulting in a tighter fit between the bladder-type protective structure 500 and the scale body 400. This tight fit helps prevent foreign matter (such as rainwater and dust) from entering the interior of the scale, protecting delicate components such as internal sensors from contamination and corrosion.

[0074] The bladder-type protective structure 500, located on the other side of the scale body 400, has a triangular cross-section. This triangular structure provides greater stability and strength, effectively dissipating external shocks and vibrations. This design helps reduce deformation or damage caused by external forces and improves the structural stability of the equipment.

[0075] The bladder-type protective structure 500 features different cross-sectional shapes on both sides of the scale body 400, allowing it to adapt to different operating conditions and stresses. A semicircular cross-section is suitable for applications requiring better adaptation to the shape and deformation of the scale body 400, while a triangular cross-section is suitable for applications requiring greater stability and strength. This design enhances the flexibility and durability of the device.

[0076] In one embodiment, the outer side of the triangular cross-section bladder-like protective structure 500 is concave inwardly into an arc. In an anti-cheating weighing device, the design of the bladder-like protective structure 500 can also serve as part of an anti-cheating measure. The triangular, inwardly concave outer side of the bladder-like protective structure 500 makes it more difficult for unauthorized individuals to cheat by damaging or interfering with the bladder-like protective structure 500, thereby enhancing the device's anti-cheating capabilities.
