Description

Technical Field

[0001] This application relates to the field of fencing technology, and in particular to an industrial fence. Background Technology

[0002] Industrial fencing includes factory fencing and commercial site fencing. Aluminum alloy fencing and zinc-coated steel fencing are the most common and widely used types. The main function of industrial fencing is to protect a specific area and provides a certain degree of anti-theft protection.

[0003] Common factory fences mainly consist of several horizontally arranged beams and multiple vertically spaced posts. To save materials and achieve a lightweight design, the beams and posts are usually hollow and vertically welded together.

[0004] Regarding the aforementioned technologies, a large number of large trucks frequently travel near the factory area. When loading and unloading goods, these trucks often reverse into the factory area, which can easily cause them to collide with the fence. This can result in dents on the surface of the posts or even bending of the posts themselves, increasing the distance between adjacent posts and thus reducing the anti-theft performance of the factory fence. Because the factory area is large, the fence is widely distributed, and there are many entrances for trucks to load and unload goods. A single worker cannot quickly identify areas of the fence with lower anti-theft performance simply by observation. Summary of the Invention

[0005] To address the issue of low anti-theft performance in factory fences where a single worker cannot quickly identify the location, this application provides an industrial fence.

[0006] The industrial fence provided in this application adopts the following technical solution:

[0007] An industrial fence includes several hollow beams and multiple cylindrical posts. The beams are vertically connected to the posts. The inner walls of the posts are smooth. A water bladder filled with liquid is raised and lowered inside the posts. A lifting assembly for driving the water bladder to move up and down is provided in the beams. An overflow hole is provided at the top of the water bladder. A recognition device for identifying the liquid level in the water bladder is also provided at the top of the water bladder.

[0008] By adopting the above technical solution, a lifting component is used to drive the water bladder to slide up and down within the column. When the column is deformed, such as dented or bent, the water bladder will be squeezed during the lifting process, causing the liquid level inside the bladder to rise. When the column is severely deformed, the liquid inside the water bladder will overflow from the overflow hole. The identification device can identify the liquid level in the water bladder, quickly and effectively detecting deformed columns, thereby quickly and accurately identifying columns with low anti-theft performance in the factory fence.

[0009] Optionally, the identification device includes an overflow pipe, multiple photoresistors, a light source, and an alarm element. The overflow pipe is vertically installed on the top of the water bladder and is connected to the water bladder through the overflow hole. The multiple photoresistors are vertically spaced inside the overflow pipe. The light source is located in the column. The alarm element is electrically connected to the photoresistors. The liquid in the water bladder is a solution with light-blocking properties.

[0010] By adopting the above technical solution, when the water bladder moves to the deformed part of the column, the water bladder is squeezed, and the liquid in the water bladder is squeezed into the overflow pipe. The more severe the deformation of the column, the higher the liquid level in the overflow pipe. Because the liquid in the water bladder has light-blocking properties, the liquid can submerge the photoresistors in the overflow pipe. The light emitted by the light source cannot be received by the photoresistors under the liquid surface, thus reducing the number of photoresistors connected to the alarm control. When the number of photoresistors connected to the alarm control is less than the set value, it indicates that the column at this point is severely deformed and has poor anti-theft performance. At this time, the alarm can sound an alarm to remind staff to replace the column at this point.

[0011] Optionally, a support rod is vertically installed inside the overflow pipe, the photoresistor is mounted on the support rod, a light-transmitting anti-stick layer is provided on the support rod, and the photoresistor is located between the anti-stick layer and the support rod.

[0012] By adopting the above technical solution, the photoresistor is installed inside the overflow pipe via a support rod. This allows the liquid entering the overflow pipe to fully submerge and shield the photoresistor, effectively preventing light emitted from the light source from shining onto the photoresistor through the overflow pipe wall, thus improving the accuracy of the identification device. Simultaneously, the anti-stick layer ensures that after one measurement of the column is completed, the water bladder resets, and the liquid in the overflow pipe flows back into the water bladder. At this point, the amount of liquid adhering to the photoresistor is minimal, which helps the identification device maintain high accuracy even when reused.

[0013] Optionally, a flexible support plate is provided on the top of the water bag, and the light source is located on the side of the support plate close to the photoresistor.

[0014] By adopting the above technical solution, the light source is mounted on top of the water bladder via a support plate, allowing the light emitted by the light source to be received by a photoresistor. Simultaneously, as the water bladder moves the light source up and down within the column, the light emitted by the light source illuminates the inner wall of the column. At night, when the column is corroded, holes will form in some locations. The light emitted by the light source can pass through these holes, allowing workers to quickly identify severely corroded columns and replace them.

[0015] Optionally, a cross-shaped valve is provided at the overflow orifice.

[0016] By adopting the above technical solution, the cross valve can prevent liquid from entering the overflow pipe without being squeezed due to the shaking of the water bladder, which helps to further improve the detection accuracy of the identification device.

[0017] Optionally, the lifting assembly includes a rotating rod rotatably disposed in the crossbeam, a plurality of suspension ropes connected one-to-one with the plurality of water bladders, and a driving component for driving the rotating rod to rotate, wherein one end of the suspension rope away from the water bladder is wound around the rotating rod.

[0018] By adopting the above technical solution, when it is necessary to inspect the column, the drive unit is activated, which drives the rotating rod to rotate. The rotating rod synchronously winds multiple suspension ropes, and the multiple suspension ropes pull the corresponding water bags to rise inside the column, thereby achieving the purpose of synchronously inspecting multiple columns and saving energy.

[0019] Optionally, a brush is provided at the end of the water bladder, and the brush abuts against the inner wall of the column.

[0020] By adopting the above technical solution, when the water bag rises and falls inside the column, the brush can scrape the inner wall of the column to clean the dust from the rusted areas, further improving the light transmittance of the severely rusted areas of the column, which helps staff to quickly identify and replace severely rusted columns.

[0021] Optionally, the water bladder is provided with a counterweight.

[0022] By adopting the above technical solution, after the inspection of the column is completed, the drive unit is activated, which drives the rotating rod to rotate, thereby unwinding the hoisting rope. The counterweight can accelerate the water bag to fall back to the bottom of the column, which helps to detect and identify the deformation and corrosion of the column in the next inspection.

[0023] Optionally, a solar panel is provided on the column / beam, and the solar panel is electrically connected to the light source.

[0024] By adopting the above technical solution, solar panels can convert solar energy into electrical energy, thereby powering the light source and achieving energy-saving and environmentally friendly effects.

[0025] Optionally, the column is provided with a maintenance window for inspecting the identification device.

[0026] By adopting the above technical solution, the installation of the inspection window allows staff to quickly remove the identification device from the post for repair and maintenance without damaging the fence.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the water bladder moves to the deformed part of the column, the water bladder is squeezed, and the liquid in the water bladder is squeezed into the overflow pipe. The liquid can submerge the photoresistor in the overflow pipe, and the light emitted by the light source cannot be received by the photoresistor under the liquid surface, which reduces the number of photoresistors connected to the alarm control. When the number of photoresistors connected to the alarm control is less than the set value, it indicates that the column is severely deformed and has poor anti-theft performance. At this time, the alarm can sound an alarm to remind the staff to replace the column at this location.

[0029] 2. The anti-stick layer ensures that after one measurement of the column is completed, the water bladder resets and the liquid in the overflow pipe flows back into the water bladder. At this time, the amount of liquid adhering to the periphery of the photoresistor is small, which helps the recognition device to maintain high accuracy when it is reused.

[0030] 3. When the water bag moves the light source up and down inside the column, the light emitted by the light source can shine on the inner wall of the column. At night, when the column is corroded, holes will be generated in some places. The light emitted by the light source can pass through the holes, allowing the staff to quickly identify the severely corroded column and replace it. Attached Figure Description

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0036] This application discloses an industrial fence. (Refer to...) Figure 1 and Figure 2An industrial fence includes several hollow crossbeams 1 and multiple cylindrical posts 2. In this embodiment, one crossbeam 1 is provided and is horizontally installed on top of multiple posts 2. The multiple posts 2 are vertically spaced along the length of the crossbeams 1, and all posts 2 are welded to the crossbeams 1. To slow down the wear rate of the outer wall of the posts 2, in this embodiment, the posts 2 are cylindrical, and the inner wall of the posts 2 is smooth. A water bladder 3 containing liquid is installed vertically inside the posts 2. The liquid in the water bladder 3 is a solution with light-blocking properties. In this embodiment, the liquid in the water bladder 3 is ink. The crossbeam 1 is equipped with a lifting assembly for driving the water bladder 3 to move up and down. The top of the water bladder 3 is provided with an overflow hole 5. The top of the water bladder 3 is also provided with an identification device for identifying the liquid level in the water bladder 3. The side wall of the column 2 is provided with an inspection window 14 for inspecting the identification device. The inspection window 14 is located at the bottom of the column 2, and a cover plate is provided on the column 2 at the inspection window 14.

[0037] The lifting assembly drives the water bladder 3 to slide up and down within the column 2. When the column 2 is deformed, such as dented or bent, the water bladder 3 will be squeezed during the lifting process, causing the liquid level in the water bladder 3 to rise. When the column 2 is severely deformed, the liquid in the water bladder 3 will overflow from the overflow hole 5. The identification device can identify the liquid level in the water bladder 3, quickly and effectively detecting deformed columns 2, thereby quickly and accurately identifying columns 2 with low anti-theft performance in the factory fence.

[0038] Reference Figure 1 and Figure 2 The lifting assembly includes a rotating rod 41, multiple lifting ropes 42, and a drive unit 43 for rotating the rotating rod 41. The rotating rod 41 is arranged parallel to the crossbeam 1 and is rotatably mounted in the crossbeam 1 via a rotating bearing. The number of lifting ropes 42 is the same as the number of columns 2, and each of the multiple lifting ropes 42 corresponds one-to-one with a multiple of the columns 2. A flexible support plate 9 is installed on the top of the water bladder 3. The support plate 9 is circular. One end of the lifting rope 42 is tied to the support plate 9, and the other end is wound around the rotating rod 41. The position where the lifting rope 42 is tied to the support plate 9 is located at the center of gravity of the support plate 9. The drive unit 43 is specifically a servo motor. The servo motor is mounted on the crossbeam 1, and the output end of the servo motor extends into the crossbeam 1 and is fixedly connected to the end of the rotating rod 41 coaxially via a coupling.

[0039] To achieve automatic power supply to the servo motor, refer to Figure 1 and Figure 2 A solar panel 13 is provided on the column 2 / beam 1. In this embodiment, the solar panel 13 is installed and fixed on the upper surface of the beam 1, and the solar panel 13 is electrically connected to the servo motor.

[0040] When multiple columns 2 need to be tested synchronously and quickly, the servo motor can be started. The servo motor drives the rotating rod 41 to rotate. The rotating rod 41 synchronously winds multiple suspension ropes 42. The multiple suspension ropes 42 pull the corresponding water bags 3 to rise inside the columns 2, thereby achieving the purpose of synchronous testing of multiple columns 2.

[0041] After the inspection is completed, the servo motor is started, which drives the rotating rod 41 to rotate, thereby unwinding the suspension rope 42. To ensure that the water bladder 3 quickly falls back to the bottom of the column 2, refer to... Figure 2 The water bladder 3 is provided with a counterweight 12, which can be a sandbag or a stone. In this embodiment, the counterweight 12 is set as a sandbag.

[0042] To achieve accurate detection of the deformation degree of column 2, refer to Figure 2 and Figure 3 The identification device includes a transparent overflow tube 61, multiple photoresistors 62, and a light source 63. The overflow tube 61 is vertically installed on the top of the water bladder 3. One end of the overflow tube 61 is fixedly bonded to the support plate 9, and the other end is fixedly bonded to the water bladder 3. The overflow tube 61 is connected to the water bladder 3 through an overflow hole 5. A cross-shaped valve 10 is bonded to the water bladder 3 at the overflow hole 5 with waterproof adhesive. The cross-shaped valve 10 can prevent liquid from entering the overflow tube 61 without compression due to the shaking of the water bladder 3. When the suspension rope 42 stably suspends the water bladder 3, the support plate 9 is horizontally set, and the overflow tube 61 is vertically set.

[0043] Reference Figure 2 and Figure 3 The light source 63 includes multiple LEDs, which are evenly installed on the side of the support plate 9 near the photoresistor 62. All LEDs are located outside the overflow pipe 61 and are electrically connected to the solar panel 13. A brush 11 is provided at the end of the water bladder 3. To reduce the problem of the brush 11 blocking the light emitted by the LEDs, in this embodiment, the brush 11 is located at the bottom of the water bladder 3 and abuts against the inner wall of the column 2.

[0044] Reference Figure 2 and Figure 3 A support rod 7 is vertically installed inside the overflow pipe 61. The support rod 7 is fixedly mounted on the support plate 9 and is coaxial with the overflow pipe 61. Multiple photoresistors 62 are vertically spaced on the support rod 7. To minimize the risk of ink adhering to the photoresistors 62 and affecting their subsequent use, a light-transmitting anti-stick layer 8 is provided on the support rod 7. The anti-stick layer 8 can be a transparent hydrophobic coating, a transparent hydrophobic film, or a hydrophobic glass cover. In this embodiment, the anti-stick layer 8 is a hydrophobic glass cover, which is fitted onto the support rod 7. The photoresistors 62 are located between the hydrophobic glass cover and the support rod 7.

[0045] To further facilitate staff in quickly identifying poles with poor anti-theft performance, refer to Figure 1 and Figure 2 The identification device also includes an alarm element 64, which is specifically an alarm light. Multiple alarm lights are provided, and each alarm light corresponds to a pole. The alarm lights are installed and fixed on the top of the pole, and the alarm lights are electrically connected to the photoresistor 62.

[0046] The implementation principle of an industrial fence according to an embodiment of this application is as follows: a lifting assembly is used to drive the water bag 3 to slide up and down in the column 2. The water bag 3 drives the light source 63 to slide up and down in the column 2 through the bearing plate. At night, when the column 2 is corroded, holes will be generated in some places. The light emitted by the light source 63 can pass through the holes, so that the staff can quickly identify the severely corroded column 2 and replace the column 2.

[0047] When the column 2 is deformed, such as dented or bent, the water bladder 3 will be squeezed during the lifting and lowering process. The liquid in the water bladder 3 will be squeezed into the overflow pipe 61. The more severe the deformation of the column 2, the higher the liquid level in the overflow pipe 61 will be. Because the liquid in the water bladder 3 has light-blocking properties, the liquid can submerge the photoresistor 62 in the overflow pipe 61. The light emitted by the light source 63 cannot be received by the photoresistor 62 under the liquid surface, resulting in a decrease in the number of photoresistors connected to the alarm light control. When the number of photoresistors 62 connected to the alarm light control is less than the set value, it indicates that the column 2 at this location is severely deformed and has poor anti-theft performance. At this time, the alarm light can sound an alarm to remind the staff to replace the column 2 at this location.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
