Description

Technical Field

[0001] This utility model relates to the field of refrigerated truck technology, specifically a refrigerated truck with a compartment cleaning function. Background Technology

[0002] Refrigerated trucks are enclosed vans used to maintain the temperature of frozen or fresh goods. Refrigerated trucks can be classified according to the manufacturer, the load-bearing capacity of the chassis, and the type of the cargo box. Refrigerated trucks are commonly used to transport frozen foods, vegetables, fruits, meat products, etc.

[0003] An existing patent (publication number: CN221233691U) discloses a refrigerated truck with a self-cleaning function. By controlling the slider inside the truck to move back and forth along the slide rail, the bristles on the vertical plate at the bottom of the slider can clean the inner walls of the left and right sides of the truck, while the bristles on the top of the horizontal plate simultaneously clean the top wall of the truck. It is simple, convenient and highly practical.

[0004] However, the above technical solutions still have certain defects. In the actual operation of the above-mentioned refrigerated truck self-cleaning system, cleaning water and mixed liquid containing dust, debris and other impurities will inevitably drip from the inner wall surface of the truck compartment. Since the screw is located at the top of the truck compartment and below the cleaning area, the impurities may fall into the thread gap of the screw, which will accelerate the wear of the threads like an abrasive, and may even cause serious situations such as thread jamming. Therefore, a refrigerated truck with a compartment cleaning function is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a refrigerated truck with a compartment cleaning function to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A refrigerated truck with a compartment cleaning function includes a compartment body. A movable component is provided at the top of the inner cavity of the compartment body. The movable component includes a threaded screw horizontally arranged at the top of the inner cavity of the compartment body. A forward and reverse motor for driving the threaded screw to rotate is fixedly installed on one side of the compartment body. A T-shaped slider is threadedly connected to the outer wall of the threaded screw. A protective component is provided at the top of the inner cavity of the compartment body outside the threaded screw. The protective component includes a protective box fixedly installed outside the threaded screw. A clearance groove is opened at the bottom of the protective box. A spring plate is fixedly installed at both ends of the clearance groove. Water-blocking strips are provided in both sets of spring plates, and the other ends of the two sets of water-blocking strips are fixedly connected to the two sides of the T-shaped slider, respectively.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0011] In one alternative: the three outer sides of the U-shaped mounting plate are provided with cleaning components for cleaning the inner walls of the main body of the carriage.

[0012] In one alternative: the cleaning assembly includes water storage boxes fixedly installed on the three outer sides of the U-shaped mounting plate, and each set of water storage boxes is fixedly installed with several equally spaced nozzles on the side near the inner wall of the main body of the carriage, and a water tank is fixedly installed on the top of the main body of the carriage.

[0013] In one alternative: all three sets of water storage boxes are hollow structures, and corrugated hoses connect the water tank to the three sets of water storage boxes, with a water pump fixedly installed at one end of each corrugated hose.

[0014] In one alternative: each set of water storage boxes is equipped with brush bristles on the side closest to the inner wall of the carriage body.

[0015] In one alternative: a fixed seat is fixedly installed on the top of the inner cavity of the carriage body, and the end of the threaded screw away from the forward and reverse motor is rotatably connected to the fixed seat.

[0016] In one alternative: sliding blocks are fixedly installed at both ends of the top of the U-shaped mounting plate, and a slide rail matching the sliding blocks is fixedly installed at the top of the inner cavity of the carriage body.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention achieves efficient protection for threaded leadscrews through the synergistic effect of multiple structures. The protective box isolates the direct intrusion of cleaning water and debris, fundamentally avoiding the risk of wear and jamming caused by foreign objects entering the thread gap. The design of the T-shaped slider and water-blocking band, combined with the spring disc, achieves dynamic extension of protection during slider movement, filling the exposed gap of the clearance groove at the bottom of the protective box and effectively preventing cleaning water from splashing and eroding the leadcrew surface. This solution, through the combination of static protection and dynamic shielding, significantly improves the durability of the transmission components, ensures the long-term stable operation of the self-cleaning system, and reduces maintenance costs and failure risks.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In one embodiment, such as Figures 1-7As shown, a refrigerated truck with a compartment cleaning function includes a compartment body 100. A movable component 200 is provided at the top of the inner cavity of the compartment body 100. The movable component 200 includes a threaded screw 210 horizontally arranged at the top of the inner cavity of the compartment body 100. A forward and reverse motor 220 for driving the threaded screw 210 to rotate is fixedly installed on one side of the compartment body 100. A T-shaped slider 240 is threadedly connected to the outer wall of the threaded screw 210. A protective component 300 is provided at the top of the inner cavity of the compartment body 100 outside the threaded screw 210. The protective component 300 includes a protective box 310 fixedly installed outside the threaded screw 210. A clearance groove 311 is opened at the bottom of the protective box 310. A spring plate 320 is fixedly installed at both ends of the clearance groove 311. A water baffle 330 is provided in both sets of spring plates 320, and the other ends of the two sets of water baffles 330 are fixedly connected to the two sides of the T-shaped slider 240 respectively.

[0031] In this embodiment, a protective box 310 is used to protect the threaded screw 210, preventing cleaning water and mixed liquid containing dust, debris, and other impurities from falling into the thread gap of the threaded screw 210 when cleaning the inner wall of the main body 100 of the carriage. This would prevent the threaded screw 210 from wearing or jamming during operation. The controller starts the forward and reverse motor 220, which drives the threaded screw 210 to rotate, thereby driving the T-shaped slider 240, which is threaded to it, to move back and forth on the threaded screw 210. At this time, the water-blocking strip 330, which is fixedly connected to both sides of the bottom end of the T-shaped slider 240, works with the spring disc 320 to freely retract and unfold, so that the clearance groove 311 at the bottom of the protective box 310 is covered by the water-blocking strip 330, further preventing cleaning water from splashing onto the outer surface of the threaded screw 210. The clearance groove 311 provides sliding space for the movement of the T-shaped slider 240.

[0032] In one embodiment, such as Figure 2 and Figure 5 As shown, the top of the protective box 310 is sloping with a higher center and lower sides, so that the size of the groove 311 is larger than the bottom size of the T-shaped slider 240; the top of the protective box 310 is sloping so that the cleaning water that falls on the top of the protective box 310 can slide down along the sloping surface to prevent water from accumulating on the top.

[0033] In one embodiment, such as Figure 2 , Figure 3 as well as Figure 4As shown, the bottom end of the T-shaped slider 240 passes through the clearance groove 311 and extends to the bottom of the protective box 310. A U-shaped moving frame 250 is fixedly installed on both sides of the bottom end of the T-shaped slider 240. A U-shaped mounting plate 260 is fixedly installed on the top of the U-shaped moving frame 250. The three outer sides of the U-shaped mounting plate 260 are equipped with cleaning components for cleaning the inner wall of the carriage body 100. The cleaning components include water storage boxes 270 fixedly installed on the three outer sides of the U-shaped mounting plate 260. Each water storage box 270 has several evenly spaced nozzles 280 fixedly installed on the side closest to the inner wall of the carriage body 100. A water tank 290 is fixedly installed on the top of the carriage body 100. All three water storage boxes 270 are hollow structures. The water tank 290 and the three water storage boxes 270 are connected... All are connected by corrugated hoses, and a water pump is fixedly installed at one end of each corrugated hose. Each set of water storage boxes 270 is equipped with brush bristles 2910 on the side near the inner wall of the carriage body 100. When cleaning the inner wall of the carriage 1, the T-shaped slider 240 moves back and forth on the threaded screw 210, driving the U-shaped moving frame 250 and the U-shaped mounting plate 260 to move synchronously. Thus, the water storage boxes 270 and the nozzles 280 on the three outer sides of the U-shaped mounting plate 260 are aimed at the inner wall of the carriage body 100 to rinse, and the brush bristles 2910 are used to scrape and clean the inner wall of the carriage body 100. By adding clean water or cleaning agent to the water tank 290, the cleaning agent in the water tank 290 is drawn into the corresponding water storage box 270 through the corrugated hose.

[0034] In one embodiment, such as Figure 2 As shown, a fixed seat 230 is fixedly installed on the top of the inner cavity of the carriage body 100, and the end of the threaded screw 210 away from the forward and reverse motor 220 is rotatably connected to the fixed seat 230, making the rotation of the threaded screw 210 more stable.

[0035] In one embodiment, such as Figure 3 and Figure 4 As shown, sliding blocks 2920 are fixedly installed at both ends of the top of the U-shaped mounting plate 260, and a slide rail 2930 matching the sliding block 2920 is fixedly installed at the top of the inner cavity of the carriage body 100. By setting the sliding block 2920 and the slide rail 2930 to cooperate with each other, the movement of the U-shaped mounting plate 260 and the cleaning components is more stable.

[0036] The above embodiments disclose a refrigerated truck with a compartment cleaning function. In this embodiment, a protective box 310 is set to protect the threaded screw 210, preventing cleaning water and mixed liquid containing dust, debris and other impurities from falling into the thread gap of the threaded screw 210 when cleaning the inner wall of the main body 100 of the compartment. This would prevent the threaded screw 210 from wearing or jamming during operation. The controller starts the forward and reverse motor 220, which drives the threaded screw 210 to rotate. This, in turn, drives the T-shaped slider 240, which is threaded to it, to move back and forth on the threaded screw 210. At this time, the water-blocking strip 330, which is fixedly connected to both sides of the bottom end of the T-shaped slider 240, works with the spring disc 320 to freely retract and unfold. This allows the clearance groove 311 at the bottom of the protective box 310 to be covered by the water-blocking strip 330, further preventing cleaning water from splashing onto the outer surface of the threaded screw 210.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application 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 application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
