Description

Technical Field

[0001] This utility model belongs to the field of temperature measurement technology for the heating surface of power generation boilers, specifically a temperature measurement structure for the wall of a high-temperature heating surface. Background Technology

[0002] The heating surfaces of a power generation boiler are key components that absorb heat and transfer energy to the working fluid, water or steam. They mainly include water-cooled walls, superheaters, reheaters, and economizers. They absorb the heat from the high-temperature flue gas generated by fuel combustion through radiation or convection, heating the water into superheated steam to drive the turbine to generate electricity. The rational design of the heating surfaces directly affects the boiler's thermal efficiency, steam parameters, and safety. It is the core link in energy conversion. High-temperature heating surfaces are subjected to extremely high temperatures and pressures for a long time, which can easily lead to material oxidation, scaling, or even tube rupture due to overheating. It is necessary to monitor the metal wall temperature in real time and accurately control the operating status to prevent overheating accidents.

[0003] In existing power generation boiler heating surface temperature detection, although temperature sensors are commonly used for monitoring, there are significant limitations when installing the temperature measuring shell. Traditional clamping structures can usually only be adapted to a single model of temperature measuring shell, lacking flexible adjustment capabilities and unable to adjust the bidirectional clamping distance according to different sizes of temperature measuring shells. This rigid design leads to poor installation compatibility, making it difficult to adapt to diverse on-site installation needs. Problems such as loose clamping or misalignment are prone to occur, affecting the effective contact between the temperature sensor and the heating surface, which may ultimately lead to inaccurate temperature measurement data or decreased equipment stability. To address this, we provide a high-temperature heating surface wall temperature measurement structure. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of bidirectional adjustable clamping distance for clamping and installing different temperature measuring shells, as well as tool-free disassembly and assembly of filter screens, a high-temperature heated surface wall temperature measuring structure is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A high-temperature heated surface wall temperature measuring structure, comprising: A temperature measuring mounting plate has a first travel groove inside, and a sliding groove is formed on the inner side wall of the first travel groove. Multiple temperature measuring slots are formed on the front of the temperature measuring mounting plate. A temperature measuring shell is provided in the center of the front of the temperature measuring mounting plate, and a temperature sensor is provided on the back of the temperature measuring shell. Ventilation slots are formed on both sides of the temperature measuring shell, and slots are formed on the inner side wall of the ventilation slots. The temperature sensor is partially adapted to the temperature measuring slot. Positioning plates are fixedly installed on both sides of the temperature measuring mounting plate, and a first circular groove is formed on one side of the temperature measuring mounting plate. A bidirectional clamping and adjusting assembly is installed in the first circular groove for clamping and installing temperature measuring shells of different models.

[0006] Preferably, the bidirectional clamping adjustment assembly includes: A first transmission rod is disposed inside a first circular groove. A first anti-slip disc is fixedly installed at one end of the first transmission rod, and a first bidirectional lead screw is fixedly installed at the other end of the first transmission rod. One end of the first bidirectional lead screw is disposed in a first stroke groove via a bearing.

[0007] Preferably, the surface of the first bidirectional lead screw is threadedly connected to a first threaded block through a first threaded hole, and a slider is fixedly installed at both the upper and lower ends of the first threaded block, the slider slidingly adapting to the groove.

[0008] Preferably, a connecting frame is fixedly installed on the front of the first threaded block, a second stroke groove is provided inside the connecting frame, and a second circular groove is provided at the upper end of the connecting frame.

[0009] Preferably, a second transmission rod is provided inside the second circular groove, a second anti-slip disc is fixedly installed at the upper end of the second transmission rod, and a second bidirectional lead screw is fixedly installed at the other end of the second transmission rod. One end of the second bidirectional lead screw is set at the bottom of the second stroke groove through a bearing.

[0010] Preferably, the surface of the second bidirectional lead screw is threadedly connected to a second threaded block through a second threaded hole. The second threaded block is partially adapted to the second stroke groove. An L-shaped clamp is fixedly installed on one side of the second threaded block, and the surface of the L-shaped clamp is provided with an anti-slip pad.

[0011] Preferably, it further includes: A filter screen removal assembly is installed inside a ventilation slot and is used to remove and clean the filter screen.

[0012] Preferably, the filter removal assembly includes: A filter screen is installed inside the ventilation slot. Fixing plates are fixedly installed on both sides of the front of the filter screen. Restriction holes are opened on the surface of the fixing plates, and movable rods are installed inside the restriction holes.

[0013] Preferably, the surface of the movable rod is provided with a fixed plate and a return spring, one end of the return spring is fixedly connected to the fixed plate, the fixed plate is fixedly installed on the surface of the movable rod, and one end of the return spring is in contact with the fixed plate.

[0014] Preferably, a plug is fixedly installed at one end of the movable rod, and the plug is compatible with the slot; a pull plate is fixedly installed at the other end of the movable rod.

[0015] The beneficial effects of this utility model are: The bidirectional clamping and adjusting assembly of this invention rotates the second anti-slip disc, causing the second transmission rod and the second bidirectional lead screw to rotate. The rotation of the second bidirectional lead screw then moves the second threaded block, which in turn moves the L-shaped clamping plate, adjusting the upper and lower clamping distance of the L-shaped clamping plate. Subsequently, rotating the first anti-slip disc rotates the first transmission rod and the first bidirectional lead screw, which in turn moves the first threaded block. The first threaded block then moves the connecting frame, which in turn moves the L-shaped clamping plate to adjust the horizontal clamping distance. This bidirectional adjustment of the clamping distance allows for clamping and installing different temperature measuring shells, enhancing clamping stability and adaptability, improving the alignment accuracy between the temperature sensor and the temperature measuring tank, and ensuring accurate and reliable temperature measurement data.

[0016] The filter removal assembly of this invention allows for easy removal of the filter screen by pulling a pull plate. This pull plate simultaneously moves the movable rod, the fixed plate, and the plug, disengaging the plug from the slot and quickly releasing the filter screen from its fixation. This facilitates removal, cleaning, or replacement. Once the pull plate is released, the return spring pushes the fixed plate, causing the movable rod and plug to automatically reset, allowing the plug to re-insert into the slot. This completes the quick installation and fixation of the filter screen, enabling tool-free removal and installation. The operation is simple, effectively ensuring unobstructed ventilation channels and preventing dust accumulation from affecting the heat dissipation of the temperature sensor housing, thus improving the stability and reliability of the temperature sensor.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Specific implementation examples are given below.

[0021] Example 1: Please see Figures 1 to 6 This utility model provides a high-temperature heated surface wall temperature measuring structure, comprising: The temperature measuring mounting plate 1 has a first travel groove 2 inside, and a sliding groove 3 on the inner side wall of the first travel groove 2. Multiple temperature measuring grooves 4 are provided on the front of the temperature measuring mounting plate 1. A temperature measuring shell 5 is provided in the center of the front of the temperature measuring mounting plate 1, and a temperature sensor is provided on the back of the temperature measuring shell 5. Ventilation grooves are provided on both sides of the temperature measuring shell 5, and slots are provided on the inner side wall of the ventilation grooves. The temperature sensor is partially adapted to the temperature measuring groove 4. Positioning plates 6 are fixedly installed on both sides of the temperature measuring mounting plate 1. A first circular groove is provided on one side of the temperature measuring mounting plate 1. A bidirectional clamping adjustment component 7 is installed in the first circular groove for clamping and installing different models of temperature measuring shells 5. A filter screen removal component 8 is installed in the ventilation groove for removing and cleaning the filter screen.

[0022] In this embodiment, the temperature measuring mounting plate 1 is first installed using the positioning plate 6, and the temperature of the heating surface of the power generation boiler is detected by the temperature sensor. Secondly, the bidirectional clamping adjustment component 7 enables bidirectional adjustment of the clamping distance to clamp and install different temperature measuring shells 5, enhancing the stability and adaptability of the clamping, improving the alignment accuracy between the temperature sensor and the temperature measuring slot 4, and ensuring accurate and reliable temperature measurement data. Then, the filter screen removal component 8 enables tool-free removal and installation of the filter screen 801, simplifying the operation and effectively ensuring the unobstructed flow of the ventilation slots, preventing dust accumulation from affecting the heat dissipation effect of the temperature measuring shell 5.

[0023] Example 2: Based on Embodiment 1, a bidirectional clamping adjustment component 7 is further disclosed.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bidirectional clamping adjustment assembly 7 includes: A first transmission rod 701 is disposed inside a first circular groove. A first anti-slip disc 702 is fixedly installed at one end of the first transmission rod 701, and a first bidirectional lead screw 703 is fixedly installed at the other end. One end of the first bidirectional lead screw 703 is disposed within a first stroke groove 2 via a bearing. A first threaded block 704 is threadedly connected to the surface of the first bidirectional lead screw 703 through a first threaded hole. Slider blocks 705 are fixedly installed at both the upper and lower ends of the first threaded block 704, and the sliders 705 slide and adapt to the groove 3. A connecting frame 706 is fixedly installed on the front of the first threaded block 704, and a second stroke groove 707 is formed inside the connecting frame 706. The upper end of the frame 706 is provided with a second circular groove, and a second transmission rod 708 is provided inside the second circular groove. A second anti-slip disc 709 is fixedly installed at the upper end of the second transmission rod 708, and a second bidirectional lead screw 710 is fixedly installed at the other end of the second transmission rod 708. One end of the second bidirectional lead screw 710 is set at the inner bottom of the second stroke groove 707 through a bearing. A second threaded block 711 is threadedly connected to the surface of the second bidirectional lead screw 710 through a second threaded hole. The second threaded block 711 is partially adapted to the second stroke groove 707. An L-shaped clamping plate 712 is fixedly installed on one side of the second threaded block 711, and an anti-slip pad is provided on the surface of the L-shaped clamping plate 712.

[0025] In this embodiment, rotating the second anti-slip disc 709 drives the second transmission rod 708 and the second bidirectional lead screw 710 to rotate. The rotation of the second bidirectional lead screw 710 then moves the second threaded block 711, which in turn moves the L-shaped clamping plate 712, adjusting the vertical clamping distance. Next, rotating the first anti-slip disc 702 drives the first transmission rod 701 and the first bidirectional lead screw 703 to rotate. The rotation of the first bidirectional lead screw 703 then moves the first threaded block 704, which in turn moves the connecting frame 706. The connecting frame 706 then adjusts the horizontal clamping distance of the L-shaped clamping plate 712. This bidirectional adjustment of the clamping distance allows for clamping and installing different temperature measuring shells 5, enhancing clamping stability and adaptability, improving the alignment accuracy between the temperature sensor and the temperature measuring groove 4, and ensuring accurate and reliable temperature measurement data.

[0026] Example 3: Based on Example 1, a filter screen removal assembly 8 is further disclosed.

[0027] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the filter removal assembly 8 includes: A filter screen 801 is installed inside the ventilation slot. Fixing plates 802 are fixedly installed on both sides of the front of the filter screen 801. A limiting hole is opened on the surface of the fixing plate 802. A movable rod 803 is installed inside the limiting hole. A fixing plate 804 and a return spring 805 are installed on the surface of the movable rod 803. One end of the return spring 805 is fixedly connected to the fixing plate 804. The fixing plate 804 is fixedly installed on the surface of the movable rod 803. One end of the return spring 805 is in contact with the fixing plate 802. A plug 806 is fixedly installed on one end of the movable rod 803 and the plug 806 is compatible with the slot. A pull plate 807 is fixedly installed on the other end of the movable rod 803.

[0028] In this embodiment, when a person pulls the pull plate 807, the movable rod 803, the fixed plate 804, and the plug 806 will move simultaneously, causing the plug 806 to disengage from the slot and quickly release the fixing restriction on the filter screen 801, making it easy to remove for cleaning or replacement. After the pull plate 807 is released, the elastic force of the return spring 805 will push the fixed plate 804, causing the movable rod 803 and the plug 806 to automatically reset, allowing the plug 806 to be reinserted into the slot, completing the quick installation and fixing of the filter screen 801. This achieves tool-free disassembly and assembly of the filter screen 801, making the operation simple and effectively ensuring the unobstructed flow of the ventilation slot, avoiding the impact of dust accumulation on the heat dissipation effect of the temperature measuring shell 5, and improving the stability and reliability of the temperature sensor.
