Description

Technical Field

[0001] This utility model relates to the field of heat pump cleaning technology, and in particular to an air source heat pump cleaning device. Background Technology

[0002] Air source heat pumps, as a highly efficient, environmentally friendly, and energy-saving energy utilization method, have been widely used in recent years in various fields such as building heating, hot water supply, industrial drying, and agricultural greenhouses. Their working principle is based on the reverse Carnot cycle, consuming a portion of mechanical work (such as electrical energy) to transfer heat from the air along with electrical energy to a high-temperature environment for application. However, as air source heat pumps are used over time, a large amount of dust often accumulates on their top, which not only affects the equipment's heat dissipation effect but may also reduce its operating efficiency and lifespan.

[0003] Traditional cleaning methods mostly rely on manual labor, which is inefficient. Cleaning personnel need to climb to the top of the equipment and use brushes or rags, which is not only time-consuming and labor-intensive but also poses certain safety risks. Furthermore, air source heat pumps of different sizes are more difficult to clean due to their varying heights, requiring ladders or scaffolding of different heights, increasing the difficulty and cost of cleaning.

[0004] Patent application CN202021779631.5 discloses a "dust cleaning device for the casing of an air source heat pump, including a base mechanism, a lifting mechanism fixedly connected to the upper end of the base mechanism, and a cleaning mechanism rotatably connected to the upper end of the lifting mechanism. In use, the device is moved next to the air source heat pump, and according to the height of the air source heat pump, a locking block is pulled out, and a telescopic rod is pulled to raise the telescopic rod, causing the cleaning disc to rise. The locking block is then inserted and passes through the first slot and engages with the second slot to fix the raised telescopic rod. The motor is then started, causing the cleaning disc to rotate and clean the air source heat pump. This application allows manual adjustment of the cleaning disc height for air source heat pumps of different heights, effectively reducing manual workload and improving cleaning efficiency." However, in this application, the distance and angle between the cleaning structure and the lifting mechanism are fixed, resulting in poor flexibility of the cleaning disc during the cleaning process. Furthermore, the addition of a motor inside the cleaning mechanism increases the weight of the upper part of the device, making it more difficult to manually move the cleaning disc.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see the appendix Figure 1-6 This embodiment discloses an air source heat pump cleaning device, comprising a support 1, a support rod 2 fixedly connected to the support 1, an adjusting rod 3 hinged to the upper end of the support rod 2, a sliding rod 4 slidably connected to the adjusting rod 3, a spring 5 installed between the sliding rod 4 and the support rod 2, a cleaning box 6 fixedly connected to the sliding rod 4, pull ropes 7 fixedly connected to both sides of the cleaning box 6, and a pulley 8 rotatably connected to the upper end of the support rod 2, which cooperates with the pull ropes 7.

[0024] Support 1 is located below support rod 2. Self-locking casters can be installed at the bottom of support 1. When moving the device, the casters reduce friction at the bottom of support 1, facilitating movement. The cross-section of support 1 is larger than that of support rod 2. Support 1 improves the stability of the bottom of support rod 2, ensuring stable support of the adjusting rod 3 and cleaning box 6 by support rod 2. Adjusting rod 3 is located at the upper end of support rod 2 and is rotatably connected to support rod 2. The angle between adjusting rod 3 and support rod 2 is variable. There is only sliding freedom between the guide rod and adjusting rod 3. Similar to the telescopic rod of the guide rod, the guide rod and the adjusting rod 3 slide together during cleaning, which can drive the cleaning box 6 to move back and forth, thereby increasing the cleaning range of the cleaning box 6. The spring 5 has a leftward elastic force on the guide rod. When the cleaning box 6 is working, pulling the pull rope 7 downward will cause the pull rope 7 to drive the guide rod to compress the spring 5 to the right through the cleaning box 6, at which time the cleaning box 6 moves to the right. After releasing the pull rope 7, the spring 5 pushes the guide rod to the left, and the guide rod drives the cleaning box 6 to move to the left, thereby realizing the reciprocating cleaning work of the cleaning box 6, increasing the cleaning area and cleaning effect.

[0025] The connecting rod 9 is located below the adjusting rod 3. A connecting rod 10 is hinged between the connecting rod 9 and the adjusting block 11. The adjusting block 11 can slide vertically on the support rod 2. When the adjusting block 11 moves upward, it drives the lower end of the connecting rod 10 to move upward. The upper end of the connecting rod 10 drives the connecting rod 9 and the adjusting rod 3 to rotate upward. The function of the connecting rod 9 is to ensure that the adjusting rod 3 can rotate to a state that is vertically collinear with the support rod 2 during the process of the connecting rod 10 driving the adjusting rod 3 to rotate upward. At this time, the side of the air source heat pump can be cleaned, and the mechanism consisting of the adjusting rod 3, the connecting rod 10 and the adjusting block 11 is not located at a dead point. The position of the adjusting block 11 on the support rod 2 is fixed by a fixing screw 12. The fixing screw 12 has a ring-shaped handle, which makes it easy for the user to adjust the adjusting block 11.

[0026] The support rod 2 is a telescopic rod structure, consisting of two sliding first support rods 201 and second support rods 202. The second support rod 202 is located inside the first support rod 201. Multiple slots 203 are distributed on the side of the second support rod 202, and the slots 203 are evenly spaced. The slots 203 on the second support rod 202 engage with the locking blocks inside the first support rod 201. The locking blocks and slots 203 work together to ensure that the position of the second support rod 202 is locked after telescopic changes.

[0027] The cavity 602 inside the cleaning box 6 is sealed to the negative pressure pipe 604. There is a rotating cleaning roller 603 inside the cavity 602. There is an opening at the bottom of the cavity 602. When the bottom surface of the housing 601 is in contact with the ground of the air source heat pump for cleaning, the negative pressure generated by the negative pressure cylinder 605 acts on the cavity 602 through the negative pressure pipe 604. As the housing 601 moves back and forth, the cleaning roller 603 will rotate. The rotating cleaning roller 603 sweeps up the dust. The dust swept up enters the negative pressure pipe 604 under the action of the negative pressure in the cavity 602, thereby completing the cleaning work on the upper part of the air source heat pump. The housing 601 and the slide rod 4 can slide relative to the adjusting rod 3. In order to make the length of the negative pressure pipe 604 always adapt to the device, the negative pressure pipe 604 is made of corrugated pipe, which has good expansion and contraction capacity. The buckle 13 on the adjusting block 11 and the adjusting rod 3 plays a role in fixing the negative pressure pipe 604.

[0028] The collection cylinder 606 is located at the front of the cavity 602. The fixed disc 6061 inside the collection cylinder 606 is made of a rigid material and functions as a roller. The fixed disc 6061 is in contact with the air heat pump. When the housing 601 moves left and right, the fixed disc 6061 begins to rotate due to friction. The rotation of the fixed disc 6061 drives the cleaning roller 603 to rotate via the pulley assembly 607. The cylindrical rods 6062 surrounding the fixed disc 6061 have… With good flexibility, the cylindrical rod 6062 can also be an elastic connecting rope. Under no external force, the cylindrical rod 6062 and the connecting rope form a cylindrical cage. When it comes into contact with a hard block, the cylindrical rod 6062 deforms, and the gap between the two cylindrical rods 6062 increases, so that the hard object enters the collection cylinder 606. The hard block is cleaned before the cleaning roller 603 arrives, thus preventing the hard block from entering the negative pressure pipe 604 and causing blockage.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
