[0030] As attached Figure 1 To be continued Figure 9 As shown:

[0031] Example 1:

[0032] This invention provides a security patrol device for power plants, comprising a patrol rail frame 2 fixedly mounted on a power plant building 1, and a patrol mechanism slidably mounted on the patrol rail frame 2 for conducting security patrols within the power plant. The patrol mechanism includes a movable base 7 slidably mounted on the patrol rail frame 2, with a patrol monitoring device 3 mounted on top of the movable base 7. A drive mechanism is mounted on the patrol rail frame 2 and the movable base 7, for driving the movable base 7 and the patrol monitoring device 3 to perform mobile patrols on the patrol rail frame 2. The drive mechanism includes a damping groove 10 formed on the top of the patrol rail frame 2, and a motor 12 is fixedly mounted inside the movable base 7, with a gear 13 fixedly mounted at the output end of the motor 12. Furthermore, gear 13 is in contact with the inner wall of damping groove 10; a charging mechanism is fixedly installed on the inspection rail frame 2 and is used to charge the inspection monitoring 3 and the mobile base 7. The charging mechanism includes a charging chamber 5 fixedly installed on the inspection rail frame 2. A lifting frame 18 is slidably installed on the top side inside the charging chamber 5. Several charging electrodes 19 are fixedly installed on the lifting frame 18. Several charging contacts 8 are fixedly installed on the top of the mobile base 7; a drying mechanism is installed inside the charging chamber 5 and is used to dry the top of the mobile base 7. The drying mechanism includes several fans 16 fixedly installed on the top side inside the charging chamber 5. Several heating plates 6 are fixedly installed on the top of the charging chamber 5.

[0033] Meanwhile, an inspection rail frame 2 is fixedly installed on the power plant building 1, allowing the movable base 7, which is slidably mounted on it, to drive the inspection monitoring 3 to move along the rail, thus achieving automatic inspection. The drive mechanism drives the gear 13 via the motor 12 to mesh with the cleat 14 on the inspection rail frame 2, and works with the limit slide 11 and ball bearings 15 to ensure smooth movement. The inspection monitoring 3 can adjust the monitoring angle via the monitoring support 9 to expand the monitoring range. The equipment is also equipped with a charging mechanism. After the inspection monitoring 3 moves to the charging compartment 5, it connects to the charging contact 8 via the charging electrode 19 on the lifting frame 18 for charging. At the same time, the drying mechanism dries and removes dust from the inspection monitoring 3 via the heating plate 6 and the fan 16 to ensure reliable charging contact. This equipment realizes automated inspection and intelligent charging of monitoring within the power plant, effectively solving the problem that traditional fixed monitoring cannot be moved for inspection, and improving inspection efficiency and equipment reliability.

[0034] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The inspection mechanism includes an inspection rail frame 2, an inspection monitoring system 3, a monitoring support base 9, a mobile base 7, and a mounting frame 4.

[0035] By fixing an inspection rail frame 2 to the side wall of the power plant building 1, several inspection monitoring devices 3 can be connected and limited on the inspection rail frame 2. This allows the inspection monitoring devices 3 to move and inspect along the side wall of the power plant building 1 via the inspection rail frame 2, thereby increasing the monitoring range of the inspection monitoring devices 3 and improving the security of the area around the power plant building 1. An installation frame 4 is fixedly connected to the bottom of the inspection rail frame 2, allowing the inspection rail frame 2 to be fixedly installed on the side wall of the power plant building 1 via several installation frames 4. Furthermore, multiple inspection rail frames 2 can be installed on the side of the inspection rail frame 2 via several installation frames 4, allowing several inspection monitoring devices 3 to be moved and supported on several inspection rail frames 2. This facilitates the combination of several inspection monitoring devices 3 and several inspection rail frames 2 to form multiple inspection lines, improving the inspection security of several inspection monitoring devices 3.

[0036] Meanwhile, a monitoring support base 9 is fixedly connected to the top of the mobile base 7, so that the mobile base 7 is movably connected to the inspection monitoring 3 through the monitoring support base 9. Thus, during use, the inspection monitoring 3 can be rotated on the top of the mobile base 7 to adjust the monitoring direction and the monitoring angle, thereby increasing the inspection monitoring range of the inspection monitoring 3 and facilitating flexible inspection use of the inspection monitoring 3.

[0037] Secondly, a control chip is fixedly installed inside the inspection monitoring 3 and the mobile base 7, so that during use, the inspection monitoring 3 and the mobile base 7 can perform inspection monitoring at a fixed time and speed along the inspection rail frame 2 according to the set program, and can also be remotely controlled by staff in the monitoring room through terminal equipment to perform mobile inspection, thereby improving the ease of use of the inspection monitoring 3.

[0038] refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The drive mechanism includes a damping groove 10, a locking tooth 14, a motor 12, a gear 13, a limiting slide groove 11, and a ball bearing 15.

[0039] A damping groove 10 is provided at the top center of the inspection rail frame 2, and several locking teeth 14 are fixedly connected to both sides of the inner wall of the damping groove 10. The locking teeth 14 are arranged at equal intervals. In addition, a motor 12 is fixedly connected inside the movable base 7, and a gear 13 is fixedly connected to the output end of the motor 12. The side wall of the gear 13 is set to mesh with the locking teeth 14, so that when the motor 12 drives the gear 13 to rotate, the teeth on the side wall of the gear 13 can engage with the locking teeth 14. This allows the motor 12 to drive the gear 13 to rotate, and the gear 13 can drive the movable base 7 to move and inspect on the inspection rail frame 2.

[0040] Meanwhile, limit grooves 11 are provided on both sides of the side wall of the inspection rail frame 2, and several balls 15 are rolledly connected on both sides of the inner wall of the mobile base 7. Several balls 15 are respectively limited and slidably connected in the two limit grooves 11. When the motor 12 drives the mobile base 7 to move on the inspection rail frame 2, the several limit grooves 11 and balls 15 can assist the sliding of the mobile base 7, thereby improving the stability of the mobile base 7 and the inspection monitoring 3 during movement. When the mobile base 7 and the inspection monitoring 3 are in use, the several limit grooves 11 and balls 15 can limit the sliding of the mobile base 7, thereby preventing the mobile base 7 and the inspection monitoring 3 from tipping over during movement and inspection.

[0041] Secondly, when using the mobile base 7, motor 12, inspection rail 2 and gear 13, it is preferable to use materials with anti-rust function so that they can be used outdoors in rainy and snowy weather. Several drainage holes are provided on the inspection rail 2 to avoid the problem of water accumulation inside the damping groove 10.

[0042] Example 2:

[0043] refer to Figure 3 , Figure 7 and Figure 8The charging mechanism includes a charging chamber 5, an electric push rod 20, a lifting frame 18, charging electrodes 19, and charging contacts 8.

[0044] By fixing the charging compartment 5 to the inspection rail frame 2, and setting the connection point between the charging compartment 5 and the inspection rail frame 2 to be located below the limiting slide groove 11 on the side wall of the inspection rail frame 2, the charging compartment 5, when fixedly connected to the inspection rail frame 2, will not affect the mobile base 7 and the inspection monitoring 3's mobile inspection and monitoring work. Furthermore, positioning chips are fixedly installed inside both the charging compartment 5 and the inspection monitoring 3, allowing the positioning chips to control the movement position of the inspection monitoring 3 during use. When recharging is required, the charging compartment 5 can be moved along the inspection rail frame 2, and the usage angle of the inspection monitoring 3 can be adjusted. This facilitates the recharging of the inspection monitoring 3 and the mobile base 7 inside the charging compartment 5, enabling the inspection monitoring 3 and the mobile base 7 to perform automatic inspection and monitoring work for extended periods.

[0045] Meanwhile, a lifting frame 18 is slidably connected to the top side of the charging compartment 5, and two charging electrodes 19 are fixedly connected to the bottom of the lifting frame 18. Two charging contacts 8 are fixedly connected to the top of the inspection monitoring 3, and the two charging contacts 8 are set as positive and negative terminals respectively, so that the positive and negative terminals of the two charging electrodes 19 and the charging contacts 8 correspond respectively. This allows the inspection monitoring 3 and the mobile base 7 to move into the charging compartment 5 when they need to be recharged, and then be lowered by the lifting frame 18 so that the two charging electrodes 19 and the charging contacts 8 make corresponding contact, thereby facilitating the recharge of the batteries in the inspection monitoring 3 and the mobile base 7.

[0046] Meanwhile, when the charging contact 8 is in use, a charging control chip is installed inside the inspection and monitoring 3. When the inspection and monitoring 3 moves into the charging compartment 5, after the charging electrode 19 contacts the charging contact 8, the charging control chip controls the charging contact 8 to be energized, so that the charging electrode 19 can work with the charging contact 8 to charge the battery inside the inspection and monitoring 3 and the mobile base 7. When the mobile base 7 and the inspection and monitoring 3 are in use, the charging control chip inside the inspection and monitoring 3 controls the two charging contacts 8 on the top of the mobile base 7 to be in a de-energized state.

[0047] Secondly, when in use, the charging compartment 5 is electrically connected to an external power source via a wire, so that the charging electrode 19 can charge the inspection monitoring 3 and the mobile base 7.

[0048] Example 3:

[0049] refer to Figure 3 and Figure 8 The drying mechanism includes a fan 16, a heating plate 6, and an air inlet 17;

[0050] Several heating plates 6 are fixedly connected to the top of the charging compartment 5, and heating wires are fixedly connected inside the heating plates 6. Several fans 16 are fixedly connected to the top side of the inside of the charging compartment 5, and the heating plates 6 and fans 16 are aligned and connected internally. In addition, several air inlets 17 are opened on the top side of the inside of the charging compartment 5, and the air inlets 17 are also connected to the fans 16 and the movable base 7. Thus, when the inspection monitoring 3 and the movable base 7 need to be recharged, the charging compartment 5 can move along the inspection rail 2 to the inside of the charging compartment 5. At this time, the fans 16 provide power to the inspection monitoring 3. 3. Air is blown from the top, and the heating wire inside the heating plate 6 is heated. The air inlet 17, which is connected to the heating plate 6 and the fan 16, can introduce outside air into the heating plate 6, where it is heated by the heating wire. The air is then blown by the fan 16 to the top of the inspection monitoring 3, which helps to dry the top of the inspection monitoring 3 and the charging contacts 8. It can also blow away the dust on the top of the inspection monitoring 3. Then, the lifting frame 18 and the charging electrode 19 are raised and lowered to charge the inspection monitoring 3 and the mobile base 7. This avoids water accumulation in the charging contacts 8, which could cause poor charging contact between the charging contacts 8 and the charging electrode 19.

[0051] Meanwhile, a filter screen is fixedly connected inside the air inlet 17, so that when the fan 16 is in use, the impurities in the air introduced by the air inlet 17 will be blocked by the filter screen installed inside the air inlet 17, thereby preventing the impurities in the air from affecting the fan 16 and the heating wire in the heating plate 6.

[0052] Working Principle: First, the entire device is installed on the side wall of the power plant building 1. The inspection rail frame 2 is fixed to the building surface via the mounting bracket 4 at the bottom. The inspection monitoring 3 is movably mounted on the inspection rail frame 2 via the movable base 7 and the monitoring support 9 on top. During the regular inspection phase, the motor 12 starts and drives the gear 13 to rotate. The gear 13 meshes with the teeth 14 on both sides of the inner wall of the damping groove 10 on the top of the inspection rail frame 2, thereby driving the movable base 7 and the inspection monitoring 3 on it to move smoothly along the inspection rail frame 2. During this process, the ball bearings 15 on both sides of the inner wall of the movable base 7 roll along the limiting grooves 11 on both sides of the outer wall of the inspection rail frame 2, which serves as a guide and prevents tipping. The inspection monitoring 3 can be rotated and its angle adjusted via the monitoring support 9, thereby enabling multi-angle and large-area dynamic monitoring of the area around the power plant building 1. The monitoring data can be transmitted to the control center in real time. When the device's power is insufficient or it enters the charging period according to the preset program, the movable base 7 carrying the inspection monitoring 3 automatically moves along the inspection rail frame 2. The inspection rail 2 moves into the charging compartment 5 fixed to the side wall of the rail. At this time, the heating plate 6 on the top of the charging compartment 5 is activated, and the heating wire inside heats the air. At the same time, the fan 16 runs, blowing the filtered warm air introduced through the air inlet 17 onto the top of the inspection monitoring 3 to dry and remove dust from the charging contacts 8 and the surface of the equipment, ensuring that the contact area is clean and dry. Subsequently, the electric push rod 20 in the charging compartment 5 pushes the lifting frame 18 down, so that the charging electrode 19 fixed on the lifting frame 18 connects with the charging contacts 8 on the top of the inspection monitoring 3. After the positive and negative terminals are connected, the battery inside the inspection monitoring 3 and the mobile base 7 begins to charge. After charging is completed, the electric push rod 20 drives the lifting frame 18 to rise and separate. The inspection monitoring 3 and the mobile base 7 move out of the charging compartment 5 along the inspection rail 2 again to continue to perform the inspection task. The whole process can realize fully automated mobile inspection, intelligent return charging and maintenance guarantee, which significantly improves the continuity, coverage and equipment reliability of power plant security monitoring.

[0053] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
