Description

Technical Field

[0001] This utility model relates to the field of power distribution room equipment technology, specifically to an early warning detection device for the ambient temperature of a power distribution room. Background Technology

[0002] As a key node connecting the power grid and the user side, the power distribution room is an important part of the power grid operation and maintenance. The traditional operation and maintenance management model of the power distribution room can no longer meet the needs of users and the requirements of lean management of the power grid. Its shortcomings are mainly reflected in the working environment, operation and maintenance mode, and monitoring methods. The working environment of the traditional power distribution room is complex, and environmental factors can easily cause abnormal equipment operation. For example, the power distribution room may have problems such as high temperature, static electricity, humidity, condensation, water immersion, water accumulation, and theft, which can easily cause equipment aging and damage, leading to insulation breakdown, partial discharge and short circuit, which pose a serious threat to the safe operation of equipment and personal safety.

[0003] Existing temperature monitoring equipment in power distribution rooms is fixed in location after installation, and its monitoring range is also fixed. This leads to an increase in the blind spot during monitoring, affecting the quality of temperature monitoring in the power distribution room. Therefore, a new technical solution needs to be designed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an early warning detection device for the ambient temperature of a power distribution room. This device addresses the technical problem that current power distribution room temperature monitoring equipment is fixed in position after installation, and the monitoring range is fixed, which increases the blind zone of temperature monitoring and affects the quality of temperature monitoring in the power distribution room.

[0005] To achieve the objective of this utility model, the technical solution adopted is as follows: A pre-warning detection device for the ambient temperature of a power distribution room is designed, comprising:

[0006] A moving mechanism, located at the top center of the internal cavity of the power distribution room, comprises:

[0007] A fixed plate has a groove on the side facing the electrical equipment inside the power distribution room. A slider is slidably connected in the groove. An infrared thermal imager is installed at the bottom of the slider. The infrared thermal imager is electrically connected to an external alarm after the signal is processed by a control processor of existing technology through a wire.

[0008] A horizontal moving component is disposed between the slider and the slide groove, and is used to drive the slider to slide back and forth along the slide groove so as to realize the infrared thermal imager to scan and detect the temperature field in the power distribution room in all directions.

[0009] The cable management mechanism, located between the cable and the fixed plate, is used to prevent the cable from getting tangled and affecting the horizontal movement of the infrared thermal imager.

[0010] Preferably, the cable management mechanism includes movable slots symmetrically opened at both ends of the fixed plate, a plurality of movable blocks are slidably connected in the movable slots, and a U-shaped frame is fixedly connected between two corresponding movable blocks on both sides of the fixed plate. The wires are sequentially passed through the plurality of U-shaped frames and fixed, and are distributed in an S-shape to guide the wires as they move with the slider.

[0011] Preferably, the horizontal movement component includes:

[0012] The lead screw is rotatably connected between the two ends of the inner cavity of the slide groove via bearings, and the slider sleeve is threaded on the outside of the lead screw;

[0013] A drive motor is fixedly connected to one end of a fixed plate. The drive end of the drive motor is connected to a bidirectional lead screw via a coupling to drive the bidirectional lead screw to rotate and drive the slider to reciprocate along the slide groove.

[0014] Preferably, a traction rope is fixedly connected to one end of the slider near the U-shaped frame, and the traction rope is sequentially threaded through and fixed to multiple U-shaped frames in an S-shaped distribution.

[0015] Preferably, the length of the traction rope between two adjacent U-shaped frames is less than the length of the conductor between two adjacent U-shaped frames.

[0016] Preferably, the infrared thermal imager is fixedly connected to a mounting plate at one end near the slider, and a fixing bolt passes through the mounting plate and is threadedly connected to the surface of the slider.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. Full-area temperature field monitoring: The infrared thermal imager is driven to slide back and forth along the slide groove by the horizontal moving component, thereby realizing a full horizontal scan of the top of the power distribution room, increasing the temperature monitoring area inside the power distribution room and avoiding the monitoring blind spots caused by the traditional fixed temperature monitoring method.

[0019] 2. Real-time dynamic detection: The infrared thermal imager continuously collects temperature data as the slider moves, and the signal is processed in real time by the control processor. When overheating of electrical equipment or cables is detected, an alarm is triggered in time.

[0020] 3. Stable equipment operation: The cable management mechanism guides the cable to be distributed in an S-shaped trajectory. When the moving block slides with the slider, the U-shaped frame pulls the cable to form a retractable S-shaped bend, avoiding the infrared thermal imager from jamming or breaking due to cable entanglement and pulling, and ensuring that the infrared thermal imager maintains stable signal transmission during reciprocating movement.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: An early warning detection device for ambient temperature in a power distribution room, see [link to example]. Figures 1 to 3 ,include:

[0027] A moving mechanism is located at the top center of the inner cavity of the power distribution room body 1. The moving mechanism includes:

[0028] The fixed plate 2 has a groove 22 on the side facing the electrical equipment inside the power distribution room body 1. The slider 23 is slidably connected in the groove 22. An infrared thermal imager 3 is installed at the bottom of the slider 23. The infrared thermal imager 3 is electrically connected to an external alarm (not shown) after the signal is processed by a control processor of the prior art through a wire 41.

[0029] A horizontal moving component is provided between the slider 23 and the slide groove 22 to drive the slider 23 to slide back and forth along the slide groove 22, so as to realize the infrared thermal imager 3 to scan and detect the temperature field in the power distribution room in all directions.

[0030] A cable management mechanism is located between the wire 41 and the fixed plate 2 to prevent the wire 41 from getting tangled and affecting the horizontal movement of the infrared thermal imager 3. The cable management mechanism includes movable grooves 42 symmetrically opened at both ends of the fixed plate 2. Multiple movable blocks 43 are slidably connected in the movable grooves 42. U-shaped frames are fixedly connected between two corresponding movable blocks 43 on both sides of the fixed plate 2. The wire 41 passes through multiple U-shaped frames 4 in sequence and is fixed, and is distributed in an S-shape to guide the wire 41 as it moves with the slider 23.

[0031] This device, through its movable mechanism and cable management mechanism, achieves the following during use:

[0032] Full-area temperature field monitoring: The infrared thermal imager 3 is driven to slide back and forth along the slide 22 by the horizontal moving component, thereby realizing a full horizontal scan of the top of the power distribution room body 1, increasing the temperature monitoring area inside the power distribution room body, and avoiding the monitoring blind spots generated by the traditional fixed temperature monitoring method.

[0033] Real-time dynamic detection: The infrared thermal imager 3 continuously collects temperature data as it moves with the slider 23. The control processor then compares the temperature data with a preset threshold. When the temperature exceeds the threshold, an alarm signal is generated to trigger the alarm.

[0034] Stable equipment operation: The cable management mechanism guides the cable 41 to be distributed in an S-shaped trajectory. When the moving block 43 slides with the slider 23, the U-shaped frame pulls the cable 41 to form a retractable S-shaped bend, avoiding the infrared thermal imager 3 from jamming or the cable 41 from breaking due to tangling. This ensures that the infrared thermal imager 3 maintains stable signal transmission during reciprocating movement.

[0035] For details, see Figure 2 The horizontal moving component includes: a lead screw 24, which is rotatably connected between the two ends of the inner cavity of the slide groove 22 via bearings, and the slider 23 is threaded on the outside of the lead screw 24; a drive motor 21, which is fixedly connected to one end of the fixed plate 2, and the drive end of the drive motor 21 is connected to the bidirectional lead screw 24 via a coupling to drive the bidirectional lead screw 24 to rotate and drive the slider 23 to reciprocate along the slide groove 22. The drive motor 21 drives the lead screw 24, thereby driving the infrared thermal imager 3 to reciprocate at the top of the inner cavity of the power distribution room body 1 (the reciprocating movement of the infrared thermal imager 3 is achieved by the forward and reverse rotation of the drive motor 21, and how the motor achieves forward and reverse rotation is a known technology, which will not be elaborated here), realizing the linear switching of the movement direction of the infrared thermal imager 3, thereby enabling uninterrupted all-round temperature monitoring inside the power distribution room body 1.

[0036] Further, see Figure 2 The slider 23 is fixedly connected to a traction rope 5 at one end near the U-shaped frame 4. The traction rope 5 is sequentially threaded through and fixed to multiple U-shaped frames 4 in an S-shape. The length of the traction rope 5 between two adjacent U-shaped frames 4 is less than the length of the wire 41 between two adjacent U-shaped frames. The length of the traction rope 5 between adjacent U-shaped frames is shorter than that of the wire 41. When the slider 23 is in operation, the traction rope 5 is tensioned before the wire 41 and bears the main tension, thereby preventing the wire 41 from breaking due to tension and further extending the service life of the wire 41.

[0037] It is worth noting that, see Figure 2The infrared thermal imager 3 is fixedly connected to a mounting plate 31 at one end near the slider 23. A fixing bolt 32 passes through the mounting plate 31 and is threadedly connected to the surface of the slider 23. The fixing bolt 32 facilitates the disassembly and assembly of the infrared thermal imager 3 and facilitates the maintenance of the infrared thermal imager 3.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model. .
