Therefore, they should not be construed as limitations on this utility model.

[0031] like Figure 1 , 2 As shown in Figures 3 and 4, a protective structure for a ground source heat pump air conditioning system is installed on the exhaust fan of the ground source heat pump air conditioner. The protective structure includes a protective device 100 and a cleaning device 200. The protective device 100 is installed on the exhaust fan to protect it and block debris, preventing hard debris from damaging the exhaust fan and avoiding soft debris from getting tangled on the exhaust fan. The cleaning device 200 is installed on the protective device 100 and allows manual cleaning of the protective device 100 to remove debris and dust.

[0032] like Figure 1 , 2 As shown in Figure 3, the protective device 100 is installed on the air intake surface of the exhaust fan, including a protective frame 1 and a filter screen 2. The protective frame 1 is mounted on the exhaust fan and is a rectangular frame. The filter screen 2 is fixedly installed in the protective frame 1 and is an integral structure with the protective frame 1. The filter screen 2 filters and protects the air, preventing various debris from entering the exhaust fan. The cleaning device 200 is installed on the air intake surface of the protective device 100 and can move up and down on the protective device 100. The cleaning device 200 includes a cleaning frame 3 and a cleaning brush 4. The cleaning frame 3 is mounted on the protective frame 1 and is used to install the cleaning brush 4. The cleaning brush 4 is located in the cleaning frame 3 and is used to clean the filter screen 2.

[0033] like Figure 3 , 4 As shown, the cleaning frame 3 further includes a movable plate 31 and a movable groove 32. The vertically arranged movable grooves 32 are arranged in pairs on the protective frame 1. The two movable grooves 32 are respectively fixed on the two sides of the protective frame 1, restricting the vertical movement trajectory of the movable plate 31, and also serving to install the movable plate 31. The movable plate 31 includes a mounting plate 311 and a sliding rod 312. The mounting plate 311 is horizontally arranged and serves as the mounting base for the cleaning brush 4. The cleaning brush 4 is detachably mounted on the inner side of the mounting plate 311. The sliding rod 312 is located at both ends of the mounting plate 311 and is located in the movable groove 32. When moving, the sliding rod 312 moves up and down along the movable groove 32, thereby driving the mounting plate 311 and the cleaning brush 4 on it to move synchronously.

[0034] The protective device 100 protects the exhaust fan, but it is prone to dust accumulation and clogging by debris. A cleaning device 200 that can move up and down is provided on the air intake surface of the protective device 100 to clean the filter screen 2 and ensure that the filter screen 2 is unobstructed and clean. Under normal circumstances, the cleaning device 200 is stored and fixed on the top of the protective frame 1 without affecting the normal protective function of the protective frame 1. When cleaning is carried out, the cleaning device 200 is manually moved up and down by the staff to clean the filter screen 2. After cleaning, the cleaning device 200 is still stored and fixed on the top of the protective frame 1.

[0035] like Figure 4 , 5 As shown in Figure 6, furthermore, the mounting plate 311 is provided with fixing clips 33, which are used to fix the cleaning device 200 when it is stored. The fixing clips 33 are arranged in pairs, with two fixing clips 33 respectively located at both ends of the mounting plate 311. Each fixing clip 33 includes a clip rod 331, a limiting spring 332, and a clip cap 333. The clip rod 331 penetrates vertically through the mounting plate 311 and can move along the axial direction of the clip rod 331 within the mounting plate 311. The inner end of the clip rod 331 is located inside the mounting plate 311. When the cleaning device 200 is stored, the inner end of the clip rod 331 is located in the fixing hole on the protective frame 1. The cleaning device 200 is fixed by the clip rod 331 being locked in the fixing hole, thus stably storing it in the protective frame 1. At the top of frame 1, when moving, the inner end of the clamping rod 331 exits from the fixing hole and presses against the surface of the protective frame 1 under the action of the limiting spring 332, but does not affect the up and down movement of the cleaning device 200. At this time, cleaning operations can be performed. The clamping cap 333 is fixedly installed at the outer end of the clamping rod 331 and is located on the outside of the mounting plate 311. The limiting spring 332 is sleeved on the outer end of the clamping rod 331 and is located between the mounting plate 311 and the clamping cap 333. The inner end of the limiting spring 332 contacts the outer side of the mounting plate 311, and the outer end of the limiting spring 332 contacts the clamping cap 333.

[0036] The locking rod 331 is movably mounted on the mounting plate 311 and can extend and retract along its own axis. Under the action of the limiting spring 332, the locking rod 331 tends to move inward. Therefore, when the locking rod 331 corresponds to the fixing hole, the locking rod 331 will be locked in the fixing hole. At this time, the cleaning device 200 is fixed and kept stable. When cleaning is required, the staff manually pulls the locking cap 333 to remove the locking rod 331 from the fixing hole and moves it to misalign the two. After releasing, the inner end of the locking rod 331 presses against the surface of the protective frame 1, but does not affect the up and down movement of the cleaning device 200. Then the staff can carry out the cleaning work. After cleaning is completed, the cleaning device 200 is moved to the top, and the locking rod 331 is aligned with the fixing hole. At this time, the locking rod 331 automatically locks into the fixing hole under the action of the limiting spring 332, realizing the function of limiting and fixing.

[0037] like Figure 4 , 7 As shown, further, the mounting plate 311 is provided with mounting seats 34, which are used to mount the cleaning brush 4, realizing the detachable connection of the cleaning brush 4. The mounting seats 34 are arranged in pairs on the mounting plate 311, with the two mounting seats 34 located at opposite ends of the cleaning brush 4. Each mounting seat 34 includes a retaining base 341 and a connecting bolt 342. The retaining base 341 is connected to the mounting plate 311 via the connecting bolt 342. The mounting plate 311 is provided with a connecting block 313, and the connecting bolt 342 is threadedly connected to the connecting block 313. The inner end of the connecting bolt 342 is connected to the retaining base 341 via a bearing. The connecting bolts of the two mounting seats 34... Both 342 are set parallel to the mounting plate 311. The two connecting bolts 342 are set back from each other. By adjusting the position of the connecting bolts 342 on the connecting block 313, the two mounting seats 34 are made to be relatively close or far apart. The top of the card seat 341 is connected to the connecting bolt 342. The card seat 341 is located inside the mounting plate 311 and fits against the inner side of the mounting plate 311. The two ends of the cleaning brush 4 are located in the card seat 341. The two card seats 341 fix the cleaning brush 4 on the mounting plate 311.

[0038] Furthermore, the card holder 341 is provided with a slot, the slots of the two card holders 341 are arranged opposite each other, and the openings of the slots are all facing the cleaning brush 4, and the end of the cleaning brush 4 is inserted into or removed from the opening of the slot.

[0039] The connecting bolt 342 and the connecting block 313 are connected by a thread. The connecting bolt 342 rotates within the connecting block 313 to move, thereby causing the retaining seat 341 to move synchronously. When installing the cleaning brush 4, the connecting bolt 342 is rotated within the connecting block 313 to move the two mounting seats 34 away from each other, creating space in between. The clean cleaning brush 4 is then placed between the two mounting seats 34, and the limiting block 314 on the mounting plate 311 is used to limit the cleaning brush 4, maintaining its stable position. Then, the connecting bolt 342 is controlled to bring the two mounting seats 34 closer together, allowing the end of the cleaning brush 4 to engage with the opening in the slot of the retaining seat 341. Once in place, the cleaning brush 4 is stably secured in the retaining seat 341. Removing the cleaning brush 4 is achieved by performing the reverse operation.

[0040] like Figure 4 As shown, the mounting plate 311 is further provided with a limiting block 314, which is located above the cleaning brush 4 and limits the cleaning brush 4.

[0041] Furthermore, the protective frame 1 is provided with a fixing hole, and when stored, the inner end of the clamp 331 is located in the fixing hole.

[0042] like Figure 3 , 4 As shown in Figure 5, the mounting plate 311 is further provided with a handle 35, which is located on the outside of the mounting plate 311 and is used by the operator to hold it. The operator controls the moving plate 31 and the cleaning brush 4 on it to move up and down by holding the handle 35.

[0043] Furthermore, the cross-section of the moving groove 32 is a T-shaped groove, and the inner end of the slide rod 312 is provided with a limiting strip. The moving plate 31 is fixed by the cooperation of the moving groove 32 and the slide rod 312, and the moving plate 31 is prevented from falling out of the moving groove 32.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
