A power plant drainage outlet temperature monitoring and early warning device and method

Abstract

This invention provides a power plant drainage outlet temperature monitoring and early warning device and method, comprising a fixing component and a monitoring assembly. The monitoring assembly includes a housing, a driving component, a flipping rod, a temperature detection rod, and an alarm. The driving component, flipping rod, and temperature detection rod are disposed within the housing. This structure allows it to be fixed to the outer wall of the drainage outlet. When temperature detection is required, the detection rod is extended closer to the water outlet; when temperature detection is not needed, the detection rod moves to the outside of the outlet. This protects the detection rod and allows for repeated measurements, i.e., reciprocating motion, enabling the detection rod to perform detection actions at intervals.

Description

Technical Field

[0001] This invention relates to a temperature monitoring and early warning device and method for power plant drainage outlets, specifically to a technology that facilitates interval monitoring of the temperature at drainage outlets and avoids damage to the probe. Background Technology

[0002] In power plant operations, large quantities of water are frequently discharged. This discharged water typically requires special treatment; otherwise, excessively high or low temperatures can negatively impact the surrounding environment. Therefore, temperature monitoring at power plant discharge outlets is common and meaningful.

[0003] In existing temperature detection technologies, the detector is typically placed at a certain distance from the drain outlet. However, it is often impossible to install a fixed temperature detector close to the drain outlet, or the detector placed at such a location is often unstable and easily damaged by strong water flow. Furthermore, leaving the temperature detector underwater at the drain outlet for extended periods can also cause damage. Moreover, existing technologies for detecting temperature at drain outlets often have shortcomings, failing to achieve rapid detection and self-protection functions, thus requiring further improvement. Summary of the Invention

[0004] To address the problems existing in the above-mentioned technologies, the present invention provides a technology for convenient real-time and protective monitoring of the location of drainage pipe outlets.

[0005] The present invention provides a power plant drainage outlet temperature monitoring and early warning device, which includes a fixing component and a monitoring component;

[0006] The fasteners are used to fix the drain pipe openings of the power plant to the outer wall of the pipe.

[0007] The monitoring component includes a housing, a drive unit, a tilting rod, a temperature detection rod, and an alarm. The drive unit, tilting rod, and temperature detection rod are housed inside the housing. The drive unit is located at one end of the tilting rod and is used to drive one side of the tilting rod to move up and down. The middle of the tilting rod is hinged to a support point. The tilting rod is connected to the inner wall of the housing via a return spring. The other side of the tilting rod is hinged to the temperature detection rod, which passes through the lower side wall of the housing and is used to extend into the opening of the power plant's drainage pipe for temperature monitoring. The temperature detected by the temperature detection rod is transmitted to the alarm, which is located on the upper side wall of the housing.

[0008] The beneficial effects of the above scheme are as follows: With this structure, it can be fixed on the outer wall of the drain pipe. When temperature detection is required, the probe is inserted into the position close to the water outlet. When temperature detection is not required, the probe is moved to the outside of the pipe opening. This can protect the probe and enable repeated measurements, i.e., reciprocating motion, so that the probe completes the detection action at intervals.

[0009] Preferably, the driving component includes a connected drive motor and a drive cam, the housing has a U-shaped mounting body, the support point of the flipping rod is disposed on the U-shaped mounting body, and the protrusion at one end of the flipping rod cooperates with the drive cam;

[0010] The housing is provided with a fixing part, the fixing part has a guide post, the temperature detection rod is hinged to the flip rod by a linkage crank, and the temperature detection rod can move through the guide hole of the guide post;

[0011] The fixing component includes a fixing bolt and a clamping plate. The clamping plate clamps and fixes the component to the outer wall of the pipe opening, and the bolt passes through the clamping plate and the outer wall of the pipe opening for fixing.

[0012] The beneficial effects of the above solution are as follows: the lifting action of the flipping rod is achieved by the contact between the protrusion of the drive cam and one side of the flipping rod, thereby realizing the detection action of the detection rod at the other end. Alternatively, the fixing component can be other existing structures, such as a clamp that directly clamps and fixes it to the outer wall of the pipe opening, or other existing fixing methods, which will not be elaborated here.

[0013] Preferably, the flipping rod is provided with an adjustment assembly, which includes an adjustment motor, an adjustment screw, and a moving block. The adjustment motor is connected to the adjustment screw, the moving block is movably disposed on the adjustment screw, and the adjustment screw is located within a limiting frame. The moving block is embedded within the limiting frame and is hinged to the end of the linkage crank.

[0014] This adjustment allows the probe's detection depth to be adjusted according to the water flow rate, specifically the flow rate of water at the pipe opening, making it easier for the probe to detect the water flow.

[0015] Preferably, the fixing component includes an extended arc-shaped track, an adjusting motor, a drive gear, and an arc-shaped toothed plate. The adjusting motor is connected to the drive gear, the drive gear meshes with the arc-shaped toothed plate, the bottom of the arc-shaped toothed plate is slidably disposed within the arc-shaped track, and one side of the arc-shaped toothed plate is connected to the housing.

[0016] This structure allows the probe rod to move circumferentially, making the detection position more accurate and allowing the probe rod to reach different heights. For example, when the flow rate at the pipe opening is low, the outflowing water is concentrated at the lower part, and by adjusting, the probe rod can be moved to a position closer to the middle and lower part of the pipe opening to successfully complete the detection.

[0017] The application method of the power plant drainage outlet temperature monitoring and early warning device provided by the present invention includes the following steps:

[0018] The fastener is installed and fixed to the outer wall of the drain pipe opening of the power plant; the power plant water is discharged through the drain pipe opening.

[0019] When it is necessary to detect the temperature of the water discharged from the pipe opening, the driving component provides power to make the flipping rod rotate around the support point, thereby moving the temperature detection rod from the outside to the inside of the pipe opening and finally touching the water flowing out of the pipe opening to complete the temperature detection; when it is not necessary to detect the temperature, the driving component provides power to keep the temperature detection rod in the outside position of the pipe opening.

[0020] The application method of the power plant drainage outlet temperature monitoring and early warning device provided by the present invention includes the following steps:

[0021] The drive motor provides power to move the drive cam. When the protrusion of the drive cam is in contact with the flipping rod, the flipping rod rotates around the support point of the U-shaped mounting body, so that the other end of the flipping rod moves towards the inside of the pipe opening, and the temperature detection rod moves along the guide hole of the guide post towards the inside of the pipe opening. When the protrusion is not in contact with the flipping rod, the return spring causes the flipping rod to move in the opposite direction, so that the other end of the flipping rod drives the temperature detection rod to move from the inside of the guide hole to the outside.

[0022] The application method of the power plant drainage outlet temperature monitoring and early warning device provided by the present invention includes the following steps: adjusting the detection depth of the temperature detection rod of the flip rod by adjusting the component, moving the adjusting screw by the adjusting motor, thereby causing the moving block to move along the axial direction of the adjusting screw and the limiting frame, so that the temperature detection rod moves away from or closer to the support point. When it moves away from the support point, the detection depth of the temperature detection rod at the pipe opening is extended, and when it moves closer to the support point, the detection depth of the temperature detection rod at the pipe opening is reduced.

[0023] The application method of the power plant drainage outlet temperature monitoring and early warning device provided by the present invention includes the following steps:

[0024] By adjusting the power provided by the motor, the drive gear rotates, thereby causing the arc-shaped toothed plate to move along the extended arc-shaped track. The extended arc-shaped track then drives the housing and temperature detector to adjust their positions along the outer circumference of the pipe opening, thereby enabling the temperature detector to complete temperature detection at different circumferential positions of the pipe opening.

[0032] First embodiment:

[0033] like Figures 1 to 3 As shown, the present invention provides a power plant drainage outlet temperature monitoring and early warning device, which includes a fixing component 10 and a monitoring component 20;

[0034] The fastener 10 is used to fix it to the outer wall 1 of the drain pipe opening of the power plant;

[0035] The monitoring component 20 includes a housing 21, a drive unit 26, a flipping rod 23, a temperature detection rod 24, and an alarm (not shown). The drive unit 26, the flipping rod 23, and the temperature detection rod 24 are disposed inside the housing 21. The drive unit 26 is disposed at one end of the flipping rod 23 and is used to drive one side of the flipping rod 23 to move up and down. The middle part of the flipping rod 23 is hinged to a support point. The flipping rod 23 is connected to the inner wall of the housing 21 by a return spring 29. The other side of the flipping rod 23 is hinged to the temperature detection rod 24. The temperature detection rod 24 passes through the lower side wall of the housing 21 and is used to extend into the pipe opening 1 of the power plant drainage pipe for temperature monitoring. The temperature detected by the temperature detection rod 24 is transmitted to the alarm, which is located on the upper side wall of the housing 21.

[0036] The application method of the power plant drainage outlet temperature monitoring and early warning device provided by the present invention includes the following steps:

[0037] The fastener 10 is installed and fixed on the outer wall 1 of the drain pipe opening of the power plant; the power plant water is discharged through the drain pipe opening 1.

[0038] When it is necessary to detect the temperature of the water discharged from the pipe opening 1, the driving component 26 provides power to make the flipping rod 23 flip around the support point, thereby driving the temperature detection rod 24 to move from the outside position of the pipe opening to the inside position, and finally touch the water flowing out of the pipe opening to complete the temperature detection; when it is not necessary to detect the temperature, the driving component 26 provides power to keep the temperature detection rod 24 in the outside position of the pipe opening.

[0039] Second embodiment:

[0040] like Figures 1 to 5 As shown, the driving component 26 includes a connected driving motor (not shown) and a driving cam 270. The housing 21 has a U-shaped mounting body 30. The support point of the flipping rod 23 is set on the U-shaped mounting body 30. The protrusion 31 at one end of the flipping rod 23 cooperates with the driving cam 270.

[0041] The housing 21 is provided with a fixing part 32, and the fixing part 32 has a guide post 33. The temperature detection rod 24 is hinged to the flip rod 23 through a linkage crank 34, and the temperature detection rod 24 can move through the guide hole of the guide post 33.

[0042] The fixing component 10 includes a fixing bolt 11 and a clamping plate 17. The clamping plate 17 clamps and fixes the component to the outer wall 1 of the pipe opening, and the bolt 11 passes through the clamping plate 17 and the outer wall 1 of the pipe opening for fixing.

[0043] The application method of the power plant drainage outlet temperature monitoring and early warning device provided by the present invention includes the following steps:

[0044] The drive motor provides power to move the drive cam 270. When the protrusion of the drive cam 270 contacts the flipping rod 23, the flipping rod 23 rotates around the support point of the U-shaped mounting body 30, so that the other end of the flipping rod 23 moves toward the inside of the pipe opening 1, and the temperature detection rod 24 moves toward the inside of the pipe opening along the guide hole 330 of the guide post 33. When the protrusion does not contact the flipping rod 23, the flipping rod 23 moves in the opposite direction through the return spring 29, so that the other end of the flipping rod 23 drives the temperature detection rod 24 to move from the inside to the outside of the guide hole 330.

[0045] Third embodiment:

[0046] like Figures 1 to 5 As shown, an adjustment assembly 40 is provided on the flip rod 23. The adjustment assembly 40 has an adjustment motor 41, an adjustment screw 42, and a moving block 43. The adjustment motor 41 is connected to the adjustment screw 42. The moving block 43 is movably disposed on the adjustment screw 42. The adjustment screw 42 is located within the limiting frame 44. The moving block 43 is embedded within the limiting frame 44. The moving block 43 is hinged to the end of the linkage crank 34.

[0047] The application method of the power plant drainage outlet temperature monitoring and early warning device provided by the present invention includes the following steps: adjusting the detection depth of the temperature detection rod 24 of the flip rod 23 by adjusting the component 40, moving the adjusting screw 42 by the adjusting motor 41, thereby causing the moving block 43 to move along the axial direction of the adjusting screw 42 and the limiting frame 44, so that the temperature detection rod 24 moves away from or closer to the support point. When it moves away from the support point, the detection depth of the temperature detection rod 24 at the pipe opening is extended, and when it moves closer to the support point, the detection depth of the temperature detection rod 24 at the pipe opening is reduced.

[0048] Fourth embodiment:

[0049] like Figures 1 to 5 As shown, the fixing member 10 includes an extended arc-shaped track 12, an adjusting motor 13, a drive gear 15, and an arc-shaped toothed plate 16. The adjusting motor 13 is connected to the drive gear 15, and the drive gear 15 meshes with the arc-shaped toothed plate 16. The bottom of the arc-shaped toothed plate 16 is slidably disposed in the arc-shaped track 12, and one side of the arc-shaped toothed plate 16 is connected to the housing 21.

[0050] The application method of the power plant drainage outlet temperature monitoring and early warning device provided by the present invention includes the following steps:

[0051] By adjusting the power provided by the motor 13, the drive gear 15 is rotated, thereby causing the arc-shaped toothed plate 16 to move along the extended arc-shaped track 12. The extended arc-shaped track 12 then drives the housing 21 and the temperature detector to adjust their positions along the outer periphery of the pipe opening, thereby enabling the temperature detection rod to complete temperature detection at different circumferential positions of the pipe opening.
