Description

Technical Field

[0001] This invention relates to the field of weighbridge equipment protection technology, specifically a weighbridge control device protection box with multiple protection functions. Background Technology

[0002] Weighbridges are widely used in chemical material settlement and production material accounting. Their junction boxes and weighing signal conditioning modules, as core components of the metering system, directly determine the reliability of the measurement data due to their operational stability. Distillation workshops are characterized by high humidity, corrosive volatile gases, and large amounts of dust, placing high demands on the corrosion resistance, tamper resistance, and cable protection performance of the weighbridge components' external protective housings.

[0003] Currently, the industry generally uses sheet metal or plastic enclosures to externally shield and protect the weighbridge components. Some standardized products use a single-layer stainless steel enclosure, equipped with a single external lock for locking, and have round holes on the side of the enclosure for cables to pass through directly. These enclosures are integrally opening and closing structures, without a separate visual observation area, and there is no matching sealing structure between the enclosure and the flip cover.

[0004] The existing protection solutions described above have the following drawbacks: they only have a single set of locks, resulting in a limited level of protection and a low threshold for forced entry, making it difficult to prevent tampering with weighing components; cables simply pass directly through pre-drilled holes in the casing, lacking dedicated limiting and fixing structures, making them highly susceptible to loosening due to long-term equipment vibration and external dragging, leading to interruptions in weighing signal transmission; the casing uses an overall opening and closing design, requiring complete unlocking and opening during inspections, posing a risk of accidental contact with internal components, and the opening process also disrupts the casing's sealed environment, allowing large amounts of dust and corrosive gases to enter. Therefore, there is an urgent need to develop a weighbridge control device protection box with multiple protection functions to overcome the shortcomings in current practical applications. Summary of the Invention

[0005] The purpose of this invention is to provide a protective box for a weighbridge control device with multiple protection functions, so as to solve the problems mentioned in the background art.

The independent locking structures of the locking assembly and the visual inspection assembly form a triple locking system of "external lock + anti-detachment pin + locking block," significantly improving resistance to forced entry and tampering. The control mechanism drives a piston via a first electric push rod, using hydraulic or pneumatic transmission to engage a rack and pinion, achieving automatic and smooth opening and closing of the top cover. Simultaneously, the control board moves, causing a sealing clamp to elastically hold the cable, effectively preventing it from loosening due to vibration or dragging, ensuring stable signal transmission. The visual inspection assembly allows operators to directly view the internal components through a transparent observation window without opening the main enclosure, avoiding the intrusion of dust and corrosive gases due to frequent opening and reducing the risk of accidental contact. Furthermore, the added purification mechanism circulates, dehumidifies, and removes dust from the air inside the enclosure, further improving the internal working environment and extending the lifespan of the components.

[0034] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0035] Please see Figures 1-3 In one embodiment of the present invention, a weighbridge control device protection box with multiple protection functions includes: a main box 1, a support frame 2 fixedly installed inside the main box 1, and a weighbridge controller 3 fixedly installed on the outer side of the top of the support frame 2; a flip-top protective cover structure, which is installed on the outer side of the top of the main box 1 to cooperate with the main box 1 to protect the weighbridge controller 3; and a control mechanism, which is connected to the main box 1 and the flip-top protective cover structure to cooperate with the main box 1 to realize the automatic opening and closing of the flip-top protective cover structure and to lock the cable 18; wherein, the flip-top protective cover structure includes: a top cover assembly, a visual inspection assembly, and a locking assembly. The top cover assembly is installed on the outer side of the top of the main box 1, one end of which is rotatably connected to the box wall of the main box 1 and connected to the control mechanism, and the other end of which is connected to the locking assembly installed on the outer side of the main box 1. The top cover assembly is provided with an openable and closable visual inspection assembly for visually viewing the operating status of the weighbridge controller 3 inside the main box 1.

[0036] Please see Figure 1 The top cover assembly includes a top cover 8 disposed on the outer side of the top of the main housing 1. A connecting rod 9 is fixedly disposed on the outer side of one end of the top cover 8. The connecting rod 9 is rotatably connected to a connecting seat fixedly disposed on the main housing 1. A gear 10 cooperating with a control mechanism is fixedly disposed on the outer side of the connecting rod 9. The other end of the top cover 8 is connected to a locking assembly disposed on the outer side of the main housing 1. In this embodiment, the control mechanism can cooperate with the gear 10 to realize the rotation of the connecting rod 9. The connecting rod 9 drives the top cover 8 to flip, realizing the automatic opening and closing of the top cover 8. When the top cover 8 is flipped onto the main housing 1, the locking assembly can lock the top cover 8. The visual inspection assembly disposed on the top cover 8 can be opened and closed independently.

[0037] Please see Figure 2 The locking assembly includes an anti-detachment pin 27 horizontally disposed on the outside of the main housing 1. The anti-detachment pin 27 is slidably connected to a limiting ring fixedly disposed on the outside of the main housing 1, and is inserted into the closed top cover 8. A locking ring is also fixedly disposed on the outside of the main housing 1, and the locking ring, in conjunction with an external padlock 28, locks the anti-detachment pin 27. After locking, the anti-detachment pin 27 restricts the opening of the top cover 8.

[0038] Please see Figure 1 and Figure 4 The visual inspection component includes a trapezoidal flip-top protective cover 4 disposed on the outside of the top cover 8. The trapezoidal flip-top protective cover 4 is provided with a transparent observation window 6 for observation. A rotating rod 5 is fixedly disposed on the outside of the trapezoidal flip-top protective cover 4. The rotating rod 5 is rotatably connected to a fixed seat 7 fixedly disposed on the top cover 8. A connecting slide plate 30 is slidably disposed on the inner side of the shell wall of the top cover 8. A transmission control frame 31 is fixedly disposed on the outside of the connecting slide plate 30. The transmission control frame 31 is connected to a second electric push rod 29 fixedly disposed on the inner side of the top cover 8. A locking plug 32 is also fixedly disposed on the outside of the connecting slide plate 30 to cooperate with the extension and retraction of the second electric push rod 29 to complete the opening and closing of the trapezoidal flip-top protective cover 4.

[0039] In this embodiment, by opening and closing the trapezoidal flip-top protective cover 4, independent control of each weighbridge operator 3 can be achieved. After the trapezoidal flip-top protective cover 4 is flipped, the second electric push rod 29 drives the connecting slide plate 30 to move through the transmission frame 31. The connecting slide plate 30 drives the locking block 32 to lock the trapezoidal flip-top protective cover 4, thereby cooperating with the locking component to complete multiple locking of the equipment.

[0040] Please see Figure 1 and Figure 5 The control mechanism includes a movable block 12 disposed on the outside of the main housing 1. The movable block 12 is slidably connected to a guide frame 13 fixedly disposed on the main housing 1. A rack 11 that meshes with a gear 10 is fixedly disposed on the outside of the movable block 12. A transmission box 14 fixedly connected to the main housing 1 is disposed on the outside of the movable block 12. A transmission tube 15 is fixedly disposed on the transmission box 14. A control piston is fixedly disposed on the outer wall of the other end of the transmission tube 15. The control piston is slidably connected to a control groove disposed on the inside of the movable block 12. A piston tube 16 is also fixedly disposed on the transmission box 14. A piston component 17 is slidably disposed on the inside of the piston tube 16. The piston component 17 is fixedly connected to a control plate 19 disposed on the inside of the main housing 1. A first electric push rod 21 is fixedly disposed between the control plate 19 and the main housing 1. In this embodiment, the piston component 17 includes a driving piston slidably disposed inside the piston tube 16 and a driving rod fixedly connected to the driving piston. The other end of the driving rod is fixedly connected to the control plate 19. The first electric push rod 21 drives the piston component 17 to move inside the piston tube 18 through the control plate 19, thereby realizing the flow of the transmission medium inside the transmission box 14. The transmission medium enters and exits the control groove along the transmission tube 15. In conjunction with the control piston, the movable block 12 is driven to move up and down along the guide frame 13. The movable block 12, through the rack 11 and gear 10, realizes the automatic opening and closing of the top cover 8.

[0041] Please see Figure 1The control mechanism also includes a sealing clamp 20 that is slidably disposed on the inner side of the bottom wall of the main housing 1. The sealing clamp 20 is slidably connected to the control plate 19. A spring is fixedly disposed between the control plate 19 and the sealing clamp 20. A rubber pad is fixedly disposed on the outer side of the sealing clamp 20 to cooperate with the lateral movement of the control plate 19 to complete the clamping and locking of the cable 18.

[0042] Please see Figure 1 The system also includes a purification mechanism, which is located inside the main housing 1 and is used to dehumidify and remove dust from the air inside the main housing 1. The purification mechanism includes a purification chamber 22 fixedly installed at the bottom of the main housing 1. An air pump 23 is installed inside the purification chamber 22. The input end of the air pump 23 is connected to the purification chamber 22 via a suction pipe 24, and the output end of the air pump 23 is connected to a processing chamber 25 located inside the purification chamber 22. A filter and desiccant are installed inside the processing chamber 25, and the output end of the processing chamber 25 is connected to an exhaust plate 26 located at the top of the purification chamber 22. Several exhaust pipes are fixedly installed on the top wall of the exhaust plate 26. In this embodiment, by setting up the purification mechanism, the air pump 23 can draw air from inside the main housing 1, and the air is sent into the processing chamber 25. The processing chamber 25 removes dust and dehumidifies the air, and the treated air is sent into the exhaust plate 26 and evenly discharged back into the main housing 1 through the exhaust plate 26.

[0043] The bottom of the main box 1 is fixedly connected to a metal support bracket by welding or bolts. The metal support bracket is a four-legged bracket structure made of angle steel, and has mounting holes at the bottom. It can be fixed to the weighbridge base or concrete ground platform by expansion bolts.

[0044] The working principle of this invention is as follows: In the normal locked state, the top cover 8 is closed onto the main housing 1, and the anti-detachment pin 27 passes through the end of the top cover 8 and is locked by the external padlock 28; at the same time, the trapezoidal flip-top protective cover 4 is closed onto the opening of the top cover 8, and the second electric push rod 29 drives the locking block 32 to insert into the side of the trapezoidal flip-top protective cover 4 through the connecting slide plate 30, forming a second locking. When inspection is required, there is no need to open the top cover 8, and the display status of the weighbridge controller 3 can be directly observed through the transparent observation window 6. When individual maintenance is required, simply unlock the locking block 32 by using the second electric push rod 29 and flip the trapezoidal flip-top protective cover 4 open. When overall maintenance or wiring is required, first open the external padlock 28 and pull out the anti-detachment pin 27. Activate the first electric push rod 21, which pushes the control plate 19 to move. The control plate 19, through the piston 17 and transmission medium, drives the movable block 12 to slide along the guide frame 13. The rack 11 on the movable block 12 drives the gear 10 to rotate, thereby causing the connecting rod 9 to automatically flip and open the top cover 8. Simultaneously, the movement of the control plate 19 drives the sealing clamp 20 via a spring, clamping or releasing the cable 18. The purification mechanism continues to operate, circulating, dehumidifying, and removing dust from the air inside the chamber to ensure a stable internal environment.

[0045] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
