Description

Technical Field

[0002] Ceiling-mounted hot water radiant panels, also simply called hot water radiant panels, ceiling radiant panels, or radiant panels, are heating devices installed on the interior ceiling of buildings. They provide heating through infrared radiation heat transfer, essentially utilizing thermal radiation technology. The system uses metal radiant panels combining tubes and plates as the radiation source, and ordinary or high-temperature hot water as the medium. The radiant panels are arranged in a series of strips and installed in a suspended ceiling. This system is superior to traditional radiator convection heating and hot air heating equipment, solving the problems of poor heating effect and high energy consumption in high-ceilinged spaces using convection methods. It is a new type of heating technology for high-ceilinged buildings. It can be used for overall heating of buildings with floor heights of 3m-30m, as well as for heating of localized areas or specific work locations. Its applications are wide-ranging, including large docks, shipbuilding, aircraft and automobile maintenance halls, building materials markets, shopping centers, exhibition halls, multi-functional stadiums, and entertainment halls, among many other places.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] Please see Figures 1 to 2 As shown, the present invention is a temperature detection device for a hot water ceiling radiant panel, including a lower surface temperature detection component 1, an upper surface temperature detection component 2, and an ambient temperature detection component 6. The lower surface temperature detection component 1 and the upper surface temperature detection component 2 are symmetrically distributed on the upper and lower sides of the radiant panel body 3. The lower surface temperature detection component 1 is used to detect the lower surface temperature of the radiant panel body 3, and the upper surface temperature detection component 2 is used to detect the upper surface temperature of the radiant panel body 3. Both the lower surface temperature detection component 1 and the upper surface temperature detection component 2 are fixed on a U-shaped frame 4, and the U-shaped frame 4 is moved along the radiant panel body 3 by a translation mechanism 5. The ambient temperature detection component 6 is set on the side of the radiant panel body 3 and is used to detect the ambient temperature at various heights below the radiant panel body 3.

[0035] Among them, such as Figures 3 to 4As shown, the lower surface temperature detection assembly 1 includes a surface temperature sensor 11, a gear 12, a rack 13, an electric push rod 14, and a mounting plate 15. The surface temperature sensor 11 is fixed to the top of the gear 12, the bottom of the gear 12 meshes with the rack 13, and the end of the rack 13 is fixedly connected to the movable end of the electric push rod 14. The bottom of the rack 13 is slidably connected to the mounting plate 15, the cylinder of the electric push rod 14 is fixed on the mounting plate 15, and the mounting plate 15 is fixed to the bottom of the U-shaped frame 4 through support plates 16. The gear 12 is rotatably disposed between the two support plates 16. The structure of the upper surface temperature detection assembly 2 is the same as that of the lower surface temperature detection assembly 1. Both the upper and lower surfaces of the U-shaped frame 4 are provided with strip-shaped through holes 41, through which the surface temperature sensor 11 passes.

[0036] In practical use, the lower surface temperature detection component 1 detects the surface temperature of the radiation plate body 3 through the surface temperature detection sensor 11. The electric push rod 14 drives the rack 13 to move, the rack 13 drives the gear 12 to rotate, and the gear 12 drives the surface temperature detection sensor 11 to rotate. Thus, the temperature of the lower surface of the radiation plate body 3 at various transverse positions can be detected through the adjustable surface temperature detection sensor 11.

[0037] Among them, such as Figure 7 As shown, the translation mechanism 5 includes a nut seat 51, a lead screw 52, ​​a translation motor 53, and a bearing seat 54. The bottom of the nut seat 51 is fixedly connected to one end of the top of the U-shaped frame 4. The nut seat 51 is movably sleeved on the lead screw 52. One end of the lead screw 52 is fixedly connected to the output shaft of the translation motor 53, and the other end of the lead screw 52 is rotatably connected to the bearing seat 54. The translation motor 53 and the bearing seat 54 are both fixed on the steel structure of the roof. Two symmetrically distributed guide rods 55 are provided on both sides of the lead screw 52. The guide rods 55 are fixed between the translation motor 53 and the bearing seat 54 and movably pass through the nut seat 51.

[0038] When the translation mechanism 5 is in use, the translation motor 53 drives the lead screw 52 to rotate, the lead screw 52 drives the nut seat 51 to move along the guide rod 55, the nut seat 51 drives the U-shaped frame 4 to move, and the U-shaped frame 4 drives the lower surface temperature detection component 1 and the upper surface temperature detection component 2 to move, thereby enabling comprehensive detection of the upper and lower surfaces of the radiation plate body 3.

[0039] Among them, such as Figures 5 to 6As shown, the ambient temperature detection component 6 includes a winding drum 61, a winding motor 62, and a wire rope 63. The frame of the winding drum 61 is fixed to the top of the U-shaped frame 4, and the drum inside the winding drum 61 is driven to rotate by the winding motor 62. The wire rope 63 is wound around the drum inside the winding drum 61, and the wire rope 63 passes through the guide wheel 64 and the L-shaped plate 7 in sequence to extend downwards. The guide wheel 64 is rotatably set inside the frame 65, and the frame 65 is fixed to the upper side of the U-shaped frame 4. The ambient temperature detection component 6 also includes a counterweight 66, a landscape panel 67, an ambient temperature detection sensor 68, and a height sensor 69. The counterweight 66 is fixed to the bottom end of the wire rope 63, the ambient temperature detection sensor 68 and the height sensor 69 are both fixed to the top of the counterweight 66, and the landscape panel 67 is fixed to the bottom of the counterweight 66.

[0040] Among them, such as Figure 8 As shown, the L-shaped plate 7 is fixed to the lower side of the U-shaped frame 4. The inner surface of the L-shaped plate 7 is provided with an arc-shaped limiting groove 71 that cooperates with the landscape plate 67. When the landscape plate 67 is in the retracted state, it is limited by the arc-shaped limiting groove 71.

[0041] In practical use, the ambient temperature detection component 6 drives the drum inside the winding drum 61 to rotate via the winding motor 62 to wind up and unwind the wire rope 63. The height of the counterweight 66 is controlled by the height sensor 69, and the ambient temperature is detected by the ambient temperature detection sensor 68, thus enabling the detection of ambient temperature at various heights. When the ambient temperature detection component 6 is not in use, the wire rope 63 drives the landscape panel 67 to rise into the L-shaped panel 7, and the arc-shaped limiting groove 71 prevents the landscape panel 67 from shaking.

[0042] The usage operation of this embodiment is as follows:

[0043] S1: In use, the temperature of the upper and lower surfaces of the radiation plate body 3 is detected by the lower surface temperature detection component 1 and the upper surface temperature detection component 2. During detection, the angle of the surface temperature detection sensor 11 is adjustable by the gear 12 and the rack 13, so that the temperature of each horizontal position on the upper and lower surfaces of the radiation plate body 3 can be detected.

[0044] S2: The translation mechanism 5 drives the lower surface temperature detection component 1 and the upper surface temperature detection component 2 to move along the radiation plate body 3, thereby enabling comprehensive detection of the upper and lower surfaces of the radiation plate body 3.

[0045] S3: When it is necessary to detect the ambient temperature, the height of the counterweight 66 is controlled by the height sensor 69, and the ambient temperature is detected by the ambient temperature detection sensor 68, so that the ambient temperature at each height can be detected.

[0046] The above are merely preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present invention.
