[0019] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0021] Secondly, the "embodiment" referred to herein refers to a specific feature, structure or characteristic that can be included in at least one implementation of the utility model. The "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. Example
[0022] Reference Figure 1-Figure 3 , this embodiment provides a shock-resistant tubular heat exchanger, comprising a tubular heat exchanger body 1 and a horizontal shock-absorbing mechanism; the horizontal shock-absorbing mechanism comprises a fixing frame 2, and when in use, the fixing frame 2 can be fixed on the vertical shock-absorbing mechanism to provide a longitudinal shock-absorbing effect for the tubular heat exchanger body 1; the fixing frame 2 has a through hole in the middle for the tubular heat exchanger body 1 to pass through, the tubular heat exchanger body 1 is located in the middle of the fixing frame 2, and a plurality of shock-absorbing components are arranged on the fixing frame 2 in a circumferential array, the shock-absorbing components comprising a connecting plate 3 fixedly connected to the fixing frame 2, and a connecting member 4 slidably connected to the connecting plate 3, more specifically, the connecting member 4 is an axis, the inner end of the connecting member 4 is connected to the outer wall of the tubular heat exchanger body 1, the connecting member 4 is slidably provided with an adjusting plate 5, the connecting member 4 is fixed with a supporting plate 6, the adjusting plate 5 is located between the connecting plate 3 and the supporting plate 6, the connecting member 4 is sleeved with a spring 7, and the two ends of the spring 7 are respectively in contact with the adjusting plate 5 and the supporting plate 6;
[0023] The horizontal damping mechanism further includes a turntable 8 rotatably connected to the fixing frame 2, the turntable 8 is provided with a plurality of driving holes 9, the driving holes 9 correspond to the adjusting plates 5 one by one, the driving holes 9 are not arranged along the radial direction of the rotating shaft 12, and a fixing shaft 10 extending into the driving hole 9 is fixed at the bottom end of the adjusting plate 5;
[0024] In this embodiment, when in use, the tubular heat exchanger body 1 is passed through the through hole in the middle of the fixing frame 2, and it is ensured that the heat exchanger is located at the center of the fixing frame 2. Then, the fixing frame 2 is fixed to the vertical shock absorbing mechanism (not shown), so that the tubular heat exchanger body 1 can provide a longitudinal shock absorbing effect. When the tubular heat exchanger body 1 is subjected to horizontal vibration, it drives the connecting parts 4 and the supporting plate 6 to move synchronously. Under the premise that the position of the adjustment plate 5 is fixed, the spring 7 will be compressed or stretched, thereby absorbing the vibration energy and reducing the displacement of the heat exchanger. There is a fixed shaft 10 at the bottom of the adjustment plate 5, and the fixed shaft 10 extends into the driving hole 9 of the turntable 8. The driving hole 9 is not arranged along the radial direction of the rotating shaft 12, so when the turntable 8 is selected, the adjustment plate 5 can be driven to move. When the shock absorbing effect needs to be adjusted, the position of the adjustment plate 5 can be changed by rotating the turntable 8, thereby changing the preload force of the spring 7 to meet different shock absorbing requirements.
[0025] As a preferred solution of the utility model, a gear ring 11 is fixed to the outside of the rotating disk 8, and a rotating shaft 12 is rotatably connected to the fixed frame 2. The rotating shaft 12 is at the end of the fixed frame 2, and a gear 13 meshing with the gear ring 11 is fixed to one end of the rotating shaft 12. The number of teeth of the gear 13 is much smaller than the number of teeth of the gear ring 11, and is used to finely adjust the angle of the gear ring 11, so that the position of the adjustment plate 5 can be accurately adjusted, and then the preload force of the spring 7 can be accurately adjusted; a worm wheel 14 is fixed to the other end of the rotating shaft 12, and a worm 15 meshing with the worm wheel 14 is rotatably connected to the fixed frame 2; a ratchet 16 is fixed to the worm wheel 14, and a pawl 17 cooperating with the ratchet 16 is rotatably connected to the fixed frame 2 through a pin shaft, and an elastic member 18 is provided on the fixed frame 2, and the elastic member 18 abuts against one end of the pawl 17; a handle 19 is fixed to the other end of the pawl 17;
[0026] In this embodiment, when it is necessary to adjust the distance between the adjustment plate 5 and the tubular heat exchanger body 1 to a smaller distance, as shown in FIG. Figure 2 and Figure 3 As shown, the worm 15 is rotated clockwise, and the worm 15 drives the ratchet 16 to rotate clockwise, and finally drives the ring gear 11 to rotate counterclockwise, so that the adjustment plate 5 moves toward the tubular heat exchanger body 1. When the ratchet 16 rotates clockwise, it can move the pawl 17 to swing with the pin as the axis. Due to the reverse force of the spring 7, the adjustment plate 5 tends to move away from the tubular heat exchanger body 1. At this time, the pawl 17 can clamp the ratchet 16, which plays a self-locking role, so that the adjustment plate 5 will not move outward due to vibration. When the position of the adjustment plate 5 needs to be adjusted outward, the handle 19 is pressed to disengage the pawl 17 from the ratchet 16, and then the worm 15 is rotated in the opposite direction.
[0027] As a preferred solution of the utility model, the adjustment plate 5 is fixed with a sliding member 20, the sliding member 20 is slidably connected to the connecting plate 3, the sliding member 20 is an optical axis, and the setting of the sliding member 20 can prevent the adjustment plate 5 from rotating.
[0028] As a preferred solution of the utility model, the fixing frame 2 is provided with a bearing 21 , and the inner ring of the bearing 21 is connected to the turntable 8 , so as to improve the rotational stability of the turntable 8 and the gear ring 11 .
[0029] As a preferred solution of the present invention, a hand wheel 22 is installed at the end of the worm 15, and the worm 15 is driven to rotate by the hand wheel 22, which makes it easier to exert force and improves convenience.
[0030] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
