Description

Technical Field

[0001] This utility model relates to the field of access control security and defense technology for hydropower stations, specifically to an outdoor access control card reader protection device, which is suitable for access control card reader protection in various complex outdoor environments (such as the emergency gate at the water intake of a hydropower station dam), especially for outdoor use scenarios that are susceptible to adverse conditions such as wind and rain erosion and mechanical collisions. Background Technology

[0002] Access control card readers are key devices in access control systems. They read information from access cards or other authorization credentials to verify user identity and permissions, thereby controlling the opening and closing of doors. Access control card readers are typically installed near outdoor gates. When an access card carrying a chip or magnetic stripe is brought close to the reader, the reader uses magnetic induction or other technologies to read the information on the card and transmits it to the access control controller, which then controls the opening or closing of the gate. Currently, outdoor access control cards are widely used in office buildings, residential communities, schools, and factories.

[0003] Traditional outdoor access control card readers typically have a shield installed on the top of the reader to prevent water from seeping into it during rain or snow and causing internal damage. However, this protective device, because the shield is usually only installed on top of the reader, can still allow rainwater to be blown onto it during rain or windy conditions. This water can then seep into the reader, causing short circuits in the internal electronic components or corrosion and reduced lifespan due to prolonged immersion. Utility Model Content

[0004] The purpose of this utility model is to provide an outdoor access control card reader protection device to address the aforementioned problems.

[0005] The technical solution of this utility model is as follows: An outdoor access control card reader protection device includes a card reader, a mounting plate, and a protective cover. The card reader is disposed between the mounting plate and the protective cover, and the mounting plate and the protective cover are fixedly connected. A power supply is provided inside the protective cover, and the power supply is electrically connected to an electric telescopic rod through a transmission line. One end of the electric telescopic rod is rotatably connected to the mounting plate, and the other end is rotatably connected to a slider. The slider is fixedly connected to a first baffle of the protective cover through a transmission block. The electric telescopic rod is extended or retracted by the power supply, which drives the slider, the transmission block, and the first baffle to move downward or upward.

[0006] With the above structure, the electric telescopic rod is extended or retracted by power supply, which drives the slider, transmission block and first baffle to move downward or upward, so as to realize the full enclosure of the card reader when it is not in use, completely isolating it from wind, rain, dust and mechanical collision.

[0007] The power supply and transmission lines are enclosed in protective covers to avoid direct exposure; electronic components are fully enclosed for protection, significantly reducing the risk of short circuits and corrosion.

[0008] Furthermore, limit blocks are fixedly provided on both sides of the slider, and the slider and limit blocks can slide up and down in the slide rail; the slide rail is fixedly provided on one inner side of the protective cover.

[0009] Through the above structure, the rigid guiding design of the slide rail and limit block ensures that the baffle is lifted and lowered without deviation or jamming, and adapts to outdoor temperature difference deformation and vibration environment.

[0010] Furthermore, both ends of the electric telescopic rod are rotatably connected to adapters; one adapter is fixedly mounted on the mounting plate, and the other adapter is connected to a slider.

[0011] The above structure illustrates in more detail how the electric telescopic pole rotates to connect the mounting plate and the slider, making the operation of the electric telescopic pole smoother and more unobstructed.

[0012] Furthermore, the protective cover also includes a second baffle, which is disposed at the bottom of the protective cover and the first baffle is disposed at the rear of the protective cover, and the first baffle and the second baffle are vertically connected.

[0013] With the above structure, the first and second baffles are raised and lowered by an electric telescopic rod, so that the card reader is fully enclosed when not in use, completely isolating it from wind, rain, dust and mechanical collisions.

[0014] Furthermore, silicone sealing strips are provided at the joints between other parts of the protective cover and the first and second baffles.

[0015] Through the above structure, the other parts of the protective cover form an elastic sealing interface with the first baffle and the second baffle, improving the waterproof rating to IP65 in the closed state and resisting strong winds and rain.

[0016] Furthermore, a bracket is fixedly installed at the upper end of the protective cover, and a proximity sensor is fixedly installed on the lower side of the bracket away from the protective cover. When the proximity sensor detects that an object is approaching the first baffle, it transmits information to the card reader, which controls the power supply to operate, thereby controlling the operation of the electric telescopic rod.

[0017] With the above structure, the barrier automatically opens when the proximity sensor detects a user approaching, without manual operation; it closes after a delay when the user leaves, balancing convenience and protection.

[0018] Furthermore, the proximity sensor is connected to the card reader via a signal line, and the surface of the proximity sensor is provided with a hydrophobic coating, while the signal line is a shielded cable.

[0019] The above structure improves the reliability of sensing in rainy and foggy weather and avoids interference from lightning strikes.

[0020] Furthermore, the card reader is equipped with two electric telescopic rods on both sides, that is, there are two electric telescopic rods, two sliders, two transmission blocks, and two slide rails.

[0021] With the above structure, two sets of drive mechanisms are set up to drive the lifting and lowering movements of the first baffle and the second baffle more stably during the operation of the device.

[0022] Furthermore, the electric telescopic rod is an IP67 waterproof electric push rod, and a rotary sealing ring is provided at the connection between the adapter and the electric telescopic rod.

[0023] The above structure prevents rainwater from seeping in along the shaft and causing motor failure.

[0024] Furthermore, a sealing gasket is fixedly provided on the side of the mounting plate away from the card reader.

[0025] Through the above structure, the cover and the baffle form a double-layer protective structure. Combined with the sealing gasket on the back of the mounting plate, it provides multi-directional sealing to prevent rainwater from seeping in (especially solving the problem of lateral wind and rain intrusion).

[0026] Compared with existing technologies, the beneficial effects of this utility model are: When the card reader is not in use, it can be wrapped for protection, which reduces the risk of rainwater intrusion caused by rain and wind, thereby improving the protection of the card reader and effectively extending its service life.

[0034] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0035] Please see Figure 1-5 An outdoor access control card reader protection device, such as Figure 1 and Figure 2 As shown, the device includes a card reader 11, a mounting plate 1, and a protective cover 12. The card reader 11 is disposed between the mounting plate 1 and the protective cover 12, and the mounting plate 1 and the protective cover 12 are fixedly connected. Figure 3 and Figure 4 As shown, a power supply 21 is installed inside the protective cover 12. The power supply 21 is electrically connected to the electric telescopic rod 24 through a transmission line 22. One end of the electric telescopic rod 24 is rotatably connected to the mounting plate 1, and the other end is rotatably connected to a slider 25. The slider 25 is fixedly connected to the first baffle 29 of the protective cover 12 through a transmission block 26. The electric telescopic rod 24 is extended or retracted by the power supply 21, which drives the slider 25, the transmission block 26, and the first baffle 29 to move downward or upward. Electric telescopic rods 24 are provided on both sides of the card reader 11, that is, there are two electric telescopic rods 24, two sliders 25, two transmission blocks 26, and two slide rails 28.

[0036] When the card reader is not in use, it can be wrapped for protection, which reduces the risk of rainwater intrusion caused by rain and wind, thereby improving the protection of the card reader and effectively extending its service life.

[0037] like Figure 5As shown, limit blocks 27 are fixedly installed on both sides of the slider 25, and the slider 25 and the limit blocks 27 can slide up and down in the slide rail 28; the slide rail 28 is fixedly installed on one inner side of the protective cover 12. Both ends of the electric telescopic rod 24 are rotatably connected to adapters 23; one adapter 23 is fixedly installed on the mounting plate 1, and the other adapter 23 is connected to the slider 25.

[0038] The protective cover 12 also includes a second baffle 210, which is disposed at the bottom of the protective cover 12. The first baffle 29 is disposed at the rear of the protective cover 12, and the first baffle 29 and the second baffle 210 are vertically connected. Silicone sealing strips are provided at the joints between other parts of the protective cover 12 and the first baffle 29 and the second baffle 210.

[0039] The bottom of the protective cover 12 may also be equipped with a concealed drainage groove (not shown in the cross-sectional view), and a hydrophobic membrane can be installed inside the groove to further improve the waterproof performance of the device. The first baffle 29 can be made of 304 stainless steel by stamping, and anti-pry steel plates can be embedded inside the slide rail 28 to improve the impact resistance of the device.

[0040] A bracket 211 is fixedly mounted on the upper end of the protective cover 12, and a proximity sensor 212 is fixedly mounted on the lower side of the end of the bracket 211 away from the protective cover 12. When the proximity sensor 212 detects an object approaching the first baffle 29, it transmits information to the card reader 11. The card reader 11 controls the power supply 21 to operate, thereby controlling the operation of the electric telescopic rod 24. The proximity sensor 212 is connected to the card reader 11 via a signal line, and the surface of the proximity sensor 212 is coated with a hydrophobic coating. The signal line is a shielded cable.

[0041] Furthermore, a hydrophobic nano-coating (such as NeverWet) can be applied to the surface of the proximity sensor 212 to prevent water film from obscuring the optical window. The sensor cable interface uses a potted sealant connector (such as an M12 connector with an IP69K protection rating). The circuit design can include a delayed shutdown module (such as closing the baffle 5 seconds after the user leaves) to avoid frequent start-stop cycles. At the software level, secondary confirmation logic is implemented (such as triggering only after continuous object detection for ≥0.5 seconds).

[0042] The proximity sensor 212 can be implemented using existing sensors, such as Turck, Omron industrial series (e.g., Omron E2E-X series), Pepperl+Fuchs capacitive sensors (e.g., QC series) or Banner outdoor-specific types (e.g., Q45 series).

[0043] The electric telescopic rod 24 is an IP67 waterproof electric push rod, and a rotary sealing ring is provided at the connection between the adapter 23 and the electric telescopic rod 24.

[0044] A sealing gasket 13 is fixedly installed on the side of the mounting plate 1 away from the card reader 11.

[0045] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
