[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Please refer to the appendix. Figures 1-5 The heat flow meter noise reduction device provided by this utility model includes a heat flow meter body 1, a stand 2 fixed to the top of the heat flow meter body 1, a rotating arm 3 fixed to the top of the stand 2, a thermal head 4 fixed to the end of the rotating arm 3, a flexible hose 5 fixedly connected to the top of the thermal head 4, and the end of the flexible hose 5 fixedly connected to the top of the heat flow meter body 1. The above structure is known to those skilled in the art and will not be described in detail. It also includes a base plate 6, a support plate 8 installed on the top of the base plate 6 through a noise reduction component, and the bottom of the heat flow meter body 1 is detachably fixed to the top of the support plate 8 through a clamping component. A self-locking universal wheel 7 is fixed to the bottom of the base plate 6, so that the device has a mobility function.

[0023] The noise reduction assembly includes several buffer rods 9, the tops of which are symmetrically hinged to the bottom of the support plate 8. Several grooves 10 are symmetrically formed on the top of the base plate 6, and sliding blocks 11 are slidably connected inside each groove 10. The bottom ends of the buffer rods 9 are respectively hinged to the tops of the sliding blocks 11. Guide rods 12 are fixed inside each groove 10. A through hole 13 is formed in the center of each sliding block 11, through which the guide rods 12 pass. Buffer springs 14 are symmetrically fixed on both sides of each sliding block 11, through which the guide rods 12 pass. The ends of the buffer springs 14 are fixed to the inner wall of the groove 10. At the top corner of the base plate 6... A damper 15 is symmetrically fixed. The top of the piston rod (not marked in the figure) of the damper 15 is fixed to the bottom of the support plate 8. Specifically, when the heat flow meter body 1 vibrates during operation, the support plate 8 can vibrate synchronously, thereby driving the sliding block 11 to slide in the slide groove 10 through the buffer rod 9. This causes the buffer spring 14 to undergo elastic deformation and generate buffer force. Combined with the damping and energy absorption effect of the damper 15, the vibration amplitude of the heat flow meter body 1 during operation can be effectively reduced, thereby reducing the noise generated by the vibration of the heat flow meter body 1 during operation, and also improving the stability of the heat flow meter body 1 during movement.

[0024] The clamping assembly includes a baffle 16, the bottom of which is fixed to the top edge of the support plate 8. Threaded holes 17 are provided at the center of both sides of the baffle 16. Adjusting screws 18 are threadedly connected to the walls of the threaded holes 17. Clamping plates 19 are rotatably mounted on the opposite ends of the two adjusting screws 18. The opposite ends of the two clamping plates 19 abut against the opposite ends of the heat flow meter body 1. Limiting holes 20 are also symmetrically provided on both sides of the baffle 16. Limiting rods 21 are symmetrically fixed on the surface of the clamping plates 19. The limiting rods 21 pass through the limiting holes 20, and the surface of the limiting rods 21 fits against the wall of the limiting holes 20. Specifically, under the combined limiting action of the limiting rods 21 and the limiting holes 20, when the operator rotates the adjusting screws 18 in the forward and reverse directions, the two clamping plates 19 rotatably mounted on the opposite ends of the adjusting screws 18 can move linearly towards each other or in the opposite direction, thereby clamping and fixing the heat flow meter body 1.

[0025] It should be noted that, in order to prevent the heat flow meter body 1 from being damaged by excessive clamping of the clamping plate 19, rubber pads can be fixedly installed at the opposite ends of the clamping plate 19 to effectively protect the heat flow meter body 1, and the rubber pads can also further improve the cushioning effect.

[0026] In summary, this utility model can add a buffer device with vibration reduction and noise reduction function to the bottom of the heat flow meter body 1. The noise reduction device is easy to disassemble and assemble, and is also suitable for use with heat flow meters of different sizes. It has good modification performance compared with the heat flow meters on the market.

[0027] The usage process of this utility model is as follows: The operator can lift the heat flow meter body 1 onto the support plate 8, and then control the two clamping plates 19 to move towards each other by rotating the adjusting screw 18, thus clamping and fixing the heat flow meter body 1 onto the support plate 8. Similarly, when the operator rotates the adjusting screw 18 in the opposite direction, the heat flow meter body 1 can be disassembled, which is convenient for disassembly and assembly. It is also suitable for clamping heat flow meters of different sizes. Compared with the heat flow meters on the market, it has good modification performance. Moreover, with the action of the self-locking universal wheel 7, the movement of the heat flow meter body 1 can be facilitated. When the heat flow meter body 1 vibrates during operation, the support plate 8 can vibrate synchronously, thereby driving the sliding block 11 to slide in the slide groove 10 through the buffer rod 9. This causes the buffer spring 14 to undergo elastic deformation to generate buffer force. Combined with the damping and energy absorption effect of the damper 15, the vibration amplitude of the heat flow meter body 1 during operation can be effectively reduced, thereby reducing the noise generated by the vibration of the heat flow meter body 1 during operation, and also improving the stability of the heat flow meter body 1 during movement.

[0028] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
