[0002] Cold chain transportation has permeated numerous related industries, and with the rapid development of the cold chain industry, the configuration of refrigerated trucks is constantly being upgraded. To ensure better airflow within the insulated compartment and maintain a uniform temperature, air duct structures are typically installed at the bottom of the refrigerated truck compartment. These air duct structures consist of multiple T-shaped protrusions arranged at equal intervals, with grooves formed between adjacent T-shaped protrusions. These grooves ensure smooth airflow even when the compartment is fully loaded, effectively maintaining a uniform temperature. Furthermore, the air duct structure also acts as a buffer; placing goods on the T-shaped protrusions prevents them from being completely pressed against the bottom of the compartment, thus preventing moisture contamination and affecting the quality of the goods. Additionally, when transporting goods with high moisture content, the grooves can also function as water collection channels, storing and draining any water dripping from the goods.

[0003] Because the air duct structure is relatively complex, it is easy for dirt to accumulate and cleaning is quite tedious. Therefore, manual cleaning is usually used. However, manual cleaning is time-consuming, labor-intensive, inefficient, and prone to overlooking cleaning dead corners, resulting in incomplete cleaning. Utility Model Content

[0039] Example 1

[0040] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides a cleaning device, including a frame 1, a first cleaning part 2, and a second cleaning part 3. The cleaning device can be installed on the frame of a grinding and cleaning vehicle and moves along the extension direction of the T-shaped protrusion of the air guide duct structure under the drive of the grinding and cleaning vehicle, thereby realizing automatic cleaning of the air guide duct structure of the refrigerated truck and improving cleaning efficiency and cleaning effect.

[0041] Specifically, the first cleaning unit 2 includes a sliding frame 21 that is slidably mounted on a frame 1, a first cleaning brush 22 mounted on the bottom of the sliding frame 21, and a pressure spring 23 pressing against the top of the sliding frame 21. Both ends of the pressure spring 23 are mounted on the frame 1. The first cleaning brush 22 can be a brush or a cotton pad. When the first cleaning brush 22 cleans the air duct structure of the refrigerated truck, it contacts the air duct structure and applies a cleaning force. At the same time, the air duct structure also applies an upward reaction force to the first cleaning brush 22, which in turn pushes the sliding frame 21 upward. Therefore, the pressure spring 23 is positioned to press against the top of the sliding frame 21, ensuring that the sliding frame 21 maintains a downward pressure under the action of the pressure spring 23. This ensures that the first cleaning brush 22 and the air duct structure remain in close contact during cleaning, guaranteeing thorough cleaning.

[0042] The second cleaning unit 3 includes several rotating cleaning components 31 arranged side by side, a linkage plate 32 that drives the rotating cleaning components 31 to rotate synchronously, and a power unit 33 that drives the linkage plate 32 to swing back and forth. The power unit 33 is an electric cylinder or an electric push rod. In an optional embodiment, the power unit 33 is an SFA80 servo electric cylinder. Specifically, the linkage plate 32 is connected to the rotating ends of the rotating cleaning components 31. When the linkage plate 32 swings under the drive of the power unit 33, it can simultaneously drive the rotating cleaning components 31 to rotate 90° synchronously. In this way, when the rotating cleaning component 31 enters the groove of the air guide structure, it can rotate 90° to an angle parallel to the extension direction of the T-shaped protrusion of the air guide structure, making it easier to insert into the groove. After the rotating cleaning component 31 is inserted into the groove, it rotates 90° to return to an angle perpendicular to the extension direction of the T-shaped protrusion, so that the rotating cleaning component 31 can make close contact with the bottom and sides of the groove after entering the groove, avoiding cleaning dead corners and ensuring good cleaning effect.

[0043] Furthermore, the second cleaning section 3 is arranged parallel to the first cleaning section 2 on the frame 1, so that the first cleaning section 2 and the second cleaning section 3 can clean the air guide structure in the same direction and at the same time, resulting in a better cleaning effect.

[0044] In a preferred embodiment, the bottom surface of the second cleaning part 3 is at a lower horizontal level than the bottom surface of the first cleaning part 2. In this way, the top surface of the T-shaped protrusion of the air guide channel structure can be cleaned by the first cleaning part 2, and the bottom and sides of the groove of the air guide channel structure can be cleaned by the second cleaning part 3, so as to achieve simultaneous and thorough cleaning of the air guide channel structure, thereby improving cleaning efficiency and cleaning effect.

[0045] like Figure 2 and Figure 4As shown, in this embodiment, the frame 1 is a "U"-shaped frame. The "U"-shaped frame makes it easier to install the first cleaning part 2 and the second cleaning part 3. Specifically, the first cleaning part 2 can be set on one side of the crossbar of the "U"-shaped frame, and the second cleaning part 3 can be parallel to the first cleaning part 2 and set on the other side of the crossbar of the "U"-shaped frame. In this way, the T-shaped protrusions and grooves of the air guide duct structure can be cleaned simultaneously by the parallel arrangement of the first cleaning part 2 and the second cleaning part 3.

[0046] like Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the rotating cleaning assembly 31 includes a rotating handle 311 rotatably mounted on the frame 1, a second cleaning brush 312 mounted at the bottom of the rotating handle 311, and a swing link 313 sleeved on the top of the rotating handle 311. The driving end shaft of the swing link 313 is hinged to the linkage plate 32.

[0047] Specifically, the power unit 33 drives the linkage plate 32 to swing and drives the rotating handle 311 to rotate through the swing linkage 313, thereby causing the second cleaning brush 312 located at the bottom of the rotating handle 311 to rotate. The size of the second cleaning brush 312 can be designed according to the size of the groove of the air guide groove structure, so that when the second cleaning brush 312 rotates in the groove to be perpendicular to the extension direction of the T-shaped protrusion, the side of the second cleaning brush 312 can make close contact with the bottom surface and two sides of the groove, achieving a cleaning effect without dead angles.

[0048] like Figure 2 and Figure 3 As shown, this embodiment also includes a top pressure plate 34 and several springs 35 arranged side by side on the bottom of the top pressure plate 34, with the other end of the springs 35 sleeved on the top of the rotating handle 311.

[0049] Specifically, there is a certain gap between the top of the rotating handle 311 and the top pressure plate 34. When the second cleaning brush 312 located at the bottom of the rotating handle 311 contacts the air guide groove structure and performs cleaning, the air guide groove structure will apply an upward reaction force to the second cleaning brush 312, thereby pushing the rotating handle 311 upward and compressing the spring 35. The spring 35 applies a downward thrust to the rotating handle 311 to ensure that the second cleaning brush 312 and the air guide groove structure maintain close contact and ensure thorough cleaning.

[0050] like Figure 5As shown, this embodiment also includes a magnetic snap fastener 314. The bottom of the rotating handle 311 is provided with a mounting groove 3111 for mounting the second cleaning brush 312. First mounting holes 31111 are provided on opposite side walls of the mounting groove 3111. The second cleaning brush 312 is provided with a second mounting hole 31211 aligned with the first mounting hole 31111. A magnetic suction part 3112 is provided on the side wall of the rotating handle 311 located at the first mounting hole 31111, which engages with the magnetic snap fastener 314. The magnetic snap fastener 314 passes through the first mounting hole 31111 and is inserted into the second mounting hole 31211. Specifically, the insert of the magnetic snap fastener 314 passes through the first mounting hole 31111 and the second mounting hole 31211, and the magnetic snap fastener 314 is attracted to the magnetic part 3112, thereby fixing the second cleaning brush 312 in the mounting groove 3111, realizing the connection between the second cleaning brush 312 and the rotating handle 311. The second cleaning brush 312 can be removed by removing the magnetic snap fastener 314 for easy replacement. The operation is simple and reduces the difficulty of maintenance and repair.

[0051] Furthermore, the second cleaning brush 312 includes a connector 3121 and a cleaning component 3122. The connector 3121 is disposed within the mounting groove 3111, and the second mounting hole 31211 penetrates the connector 3121. At least one U-shaped slot 31212 is provided on the side of the connector 3121, and the cleaning component 3122 is snapped into the U-shaped slot 31212. The cleaning component 3122 can be a brush or a cotton pad. The connection between the cleaning component 3122 and the mounting groove 3111 via the connector 3121 strengthens the structural strength of the connection, making it more reliable. Furthermore, the placement of the cleaning component 3122 within the U-shaped slot 31212 effectively reduces the width of the side of the cleaning component 3122 used for cleaning, making it less prone to bending during cleaning and ensuring cleaning effectiveness.

[0052] like Figure 4 As shown, in this embodiment, two support plates 11 are symmetrically arranged on the frame 1. The two support plates 11 form a sliding groove for the sliding frame 21 to slide up and down. The support plates 11 limit the sliding frame 21 to prevent the sliding frame 21 from detaching from the frame 1 when sliding.

[0053] Example 2

[0054] A polishing and cleaning cart is also provided, which includes a cleaning device as described in Embodiment 1. The cleaning device is mounted on the frame of the polishing and cleaning cart and is driven by the polishing and cleaning cart to move along the direction of the T-shaped protrusion of the air guide structure, thereby achieving automatic cleaning and improving cleaning efficiency.

[0055] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
