Technical Field

[0001] This utility model relates to the field of protective structure technology, specifically a protective structure for a heat exchanger. Background Technology

[0002] Heat exchangers, as key heat exchange equipment in the industrial field, are widely used in industries such as petroleum, chemical, power, and metallurgy. Their stable operation is crucial to the entire production system. However, in complex industrial environments, heat exchangers are often installed outdoors or in crowded workshops, making them highly susceptible to damage from external collisions, equipment movement, or accidental impacts caused by human error.

[0003] A search revealed a utility model patent with patent authorization announcement number CN222364463U, which discloses a heat exchanger with a protective structure, including a base and a protective rod. The heat exchanger body is mounted on the top of the base, and the protective rod is movably disposed on the front surface of the heat exchanger body. An adjustment mechanism is provided on the top of the base, and the adjustment mechanism is connected to the protective rod. The adjustment mechanism includes an adjustment component and a fixing plate, and the fixing plate is fixed to the bottom of the protective rod.

[0004] Currently, most common protective structures are directly welded or fixed to the base or equipment body using multiple bolts. While welding provides a strong connection, it lacks flexibility. When regular cleaning, maintenance, or inspection of the heat exchanger is required, the welded protective structure cannot be disassembled, severely obstructing the workspace and making maintenance extremely difficult. Bolted connections, while detachable, are cumbersome and time-consuming to install and remove, requiring specialized tools. Therefore, improvements are needed. Utility Model Content

A guide rod 14 is fixedly connected to the top inner side of the hollow shell 13. A pin 15 is slidably sleeved on the lower section of the guide rod 14. The pin 15 passes through the hollow shell 13 and is slidably connected to it. The pin 15 is inserted into the circumferential surface of the knob 11. Multiple holes are provided on the circumferential surface of the knob 11 for the insertion of the pin 15, which can lock the knob 11, thereby ensuring the stability between the bidirectional screw 10 and the threaded sleeve 9, and further ensuring the stability of the position adjustment of the two mounting feet 7. A spring 16 is provided inside the pin 15. One end of the spring 16 is fixedly connected to the guide rod 14, and the other end of the spring 16 is fixedly connected to the inner surface of the pin 15. The spring 16 can apply a reaction force to the pin 15. A push rod 17 is fixedly connected to the pin body of the pin 15. The push rod 17 passes through the hollow shell 13 and is slidably connected to the hollow shell 13.

[0026] Please see Figure 5 , Figure 6 A quick-release mechanism 6 is provided between the mounting shell 3 and the mounting plate 4. This mechanism facilitates the installation and removal of the protective frame 5 from the outside of the heat exchanger 2. The quick-release mechanism 6 includes a slidably connected inclined block 61 inside the mounting shell 3. The inclined block 61 engages with the vertical part of the mounting plate 4. A locking pin 62 is fixedly connected to the inclined block 61, penetrating the mounting plate 4 and slidably connected to it. A circular arc rod 67 is slidably connected to the bottom of the mounting shell 3, penetrating the entire shell. One end of the circular arc rod 67 is slidably connected to the inclined surface of the inclined block 61, and the other end is fixedly connected to a pressing block 66. A corrugated sleeve 68 is fixedly connected to the pressing block 66 and fixedly connected to the bottom of the mounting shell 3. Ball bearings 65 are provided at both the upper and lower ends of the inclined block 61, and these ball bearings 65 are slidably connected to the inner surface of the mounting shell 3. The ball bearing 65 reduces friction when the inclined block 61 slides within the mounting housing 3.

[0027] The specific implementation process of this utility model is as follows: First, the protective frame 5 is inserted from above the heat exchanger 2. At this time, the vertical part of the mounting plate 4 on the protective frame 5 will be inserted into the opening at the top of the mounting shell 3. During this process, the vertical part of the mounting plate 4 presses down on the inclined surface of the inclined block 61, forcing the inclined block 61 to overcome the elastic force of the second spring 64 and move axially towards the guide pin 63. When the mounting plate 4 is inserted into place, the inclined block 61 moves outward under the action of the rebound force of the second spring 64, so that the locking pin 62 on it is inserted into the preset hole on the vertical part of the mounting plate 4, thereby realizing automatic locking. At this time, the installation of the protective frame 5 is completed, which can effectively resist the impact of external collisions on the heat exchanger 2, thereby improving the safety of the heat exchanger 2. In addition, as To adjust the position of the mounting feet 7, simply push the push rod 17 upwards. The push rod 17 drives the pin 15 to overcome the elastic force of the spring 16 and exit the socket on the circumferential surface of the knob 11, releasing the lock on the knob 11. Then, the knob drives the bidirectional screw 10 to rotate. Since the threads of the two threaded sleeves 9 are opposite, the rotation of the bidirectional screw 10 will cause the two threaded sleeves 9 to drive the fixing block 8 and the mounting feet 7 to move synchronously in opposite directions, thereby adjusting the span between the two mounting feet 7 to adapt to different foundation sizes. After adjusting to the desired position, release the push rod 17. The spring 16 pushes the pin 15 back to its original position, so that its front end is inserted into the nearest socket on the knob 11, locking the knob 11 to prevent accidental rotation and ensure stability after adjustment.
