Description

Technical Field

[0001] This utility model relates to the field of refrigerated vehicle technology, and in particular to a constant temperature cold storage compartment for refrigerated vehicles. Background Technology

[0002] In the cold chain transportation industry, especially in short-distance urban transportation, refrigerated trucks are widely used, and existing refrigerated trucks are generally equipped with temperature-retaining refrigerated compartments to achieve constant temperature refrigeration.

[0003] A search revealed that patent application number 202020993374.9 discloses an energy-saving electric refrigerated truck body, comprising a cab, a truck body, and a refrigeration unit installed on the top of the truck body near the cab. A battery is installed at the bottom of the truck body, and a photovoltaic panel with a rotating mechanism is installed on top of the truck body. The photovoltaic panel is connected to the battery via wires. This prior art improves the solar energy conversion rate by designing a rotatable photovoltaic system to charge the battery, thus ensuring the refrigeration effect and driving range of the refrigerated truck.

[0004] However, in actual use, the photovoltaic panels located on the top of the carriage will be covered and corroded by external dust after a period of use, and it is inconvenient to clean them manually. This will lead to a decrease in the power generation effect of the photovoltaic panels, a corresponding reduction in the lifespan of the photovoltaic panels, and an inability to effectively remove odors from the carriage. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a constant-temperature cold storage compartment for refrigerated trucks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A refrigerated truck with constant temperature cold storage compartment includes a main controller fixedly installed on the front outer wall of the constant temperature cold storage compartment body. The top of the constant temperature cold storage compartment body is provided with a rotating photovoltaic mechanism and an active odor dissipation mechanism in sequence.

[0008] The rotary photovoltaic mechanism includes a rotary drive assembly, a fixed cover fixedly connected to the top outer wall of the constant temperature cold storage vehicle body, a rotating shaft rotatably mounted on the top of the fixed cover, a rotating seat welded to the top outer wall of the rotating shaft, a photovoltaic bracket fixedly connected to the top outer wall of the rotating seat and inclined, a photovoltaic panel fixedly mounted on the top inclined outer wall of the photovoltaic bracket, and a light sensor fixedly mounted on the upper outer wall of the photovoltaic bracket.

[0009] The photovoltaic bracket is provided with a reciprocating dust removal mechanism on the top inclined surface. The reciprocating dust removal mechanism includes a lead screw, a reciprocating slider threaded to the lead screw, a dust removal brush fixedly connected to the top outer wall of the reciprocating slider, and a servo motor fixedly connected to the lower outer wall of the photovoltaic bracket through a motor base.

[0010] The active odor dissipation mechanism includes an exhaust pipe fixedly connected to the top of the constant temperature cold storage compartment, a purification box fixedly connected to the top of the exhaust pipe, an exhaust fan fixedly installed on the outer wall of the top of the purification box, an exhaust solenoid valve installed inside the exhaust pipe, and a detachable purification component installed on the purification box.

[0011] Preferably, the rotary drive assembly includes a drive motor fixedly mounted on the side wall of the fixed cover, a driving bevel gear fixedly mounted on the output shaft of the drive motor, and a driven bevel gear fixedly mounted on the bottom end of the rotary shaft. The output shaft of the drive motor passes through one side of the fixed cover, and the driving bevel gear and the driven bevel gear mesh with each other. With the above structure, it is easy to drive the photovoltaic panel to rotate, so that the photovoltaic panel can move towards the direction of higher light intensity, which is beneficial to improving the solar energy conversion rate.

[0012] Preferably, two bearing seats are symmetrically fixed on the outer wall of the top inclined surface of the photovoltaic bracket, the lead screw is rotatably installed between the two bearing seats, and the output shaft of the servo motor is coaxially fixedly connected to the bottom end of the lead screw through a coupling. With the above structure, it is easy for the servo motor to drive the lead screw to rotate stably between the two bearing seats.

[0013] Preferably, the bottom of the cleaning brush is provided with a bristle structure, and the bristle structure is in contact with the top surface of the photovoltaic panel. With the above structure, the bristle structure at the bottom of the cleaning brush moves back and forth on the surface of the photovoltaic panel, which can effectively remove the dust attached to the surface of the photovoltaic panel, which is beneficial to improving the power generation effect of the photovoltaic panel and helping to extend the service life of the photovoltaic panel.

[0014] Preferably, a guide rail is fixedly installed on the outer wall of the top inclined surface of the photovoltaic bracket, and the guide rail is slidably connected to the reciprocating slider. Through the above structure, the guide rail limits the reciprocating slider that is threadedly connected to the lead screw, thus ensuring the stability of the linear motion of the reciprocating slider.

[0015] Preferably, the detachable purification component includes an insert plate inserted into the purification box, an activated carbon filter element fixedly embedded in the insert plate, a limiting iron plate fixedly connected to the side wall of the insert plate, and two permanent magnets fixedly embedded on one side of the purification box. With the above structure, the insert plate can be easily pulled out periodically to replace the activated carbon filter element by magnetic attraction.

[0016] Preferably, the limiting iron plate is fixedly attracted to two permanent magnets, and a handle is welded to the side wall of the limiting iron plate. With the above structure, the magnetic attraction method is also convenient for fixing the insert plate inserted into the purification box.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. It is equipped with a reciprocating dust removal mechanism. The lead screw is driven to rotate by a servo motor. Then, under the guidance of the guide rail, the reciprocating slider connected to the lead screw will drive the dust removal brush to move back and forth on the surface of the photovoltaic panel. This can effectively remove the dust attached to the surface of the photovoltaic panel, which is conducive to improving the power generation effect of the photovoltaic panel and helping to extend the service life of the photovoltaic panel.

[0019] 2. An active odor dissipation mechanism is installed. The main controller controls the exhaust solenoid valve and exhaust fan to open together. At this time, the exhaust fan will actively discharge the air in the constant temperature cold storage compartment to the outside. During the active discharge process, the air will enter the purification box from the exhaust pipe. Under the full adsorption and purification of the activated carbon filter, the odor in the air can be effectively removed, which facilitates active deodorization after the refrigerated truck compartment is unloaded, thus improving the deodorization efficiency.

Detailed Implementation

[0027] 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.

[0028] Example 1, referring to Figure 1-4 A refrigerated truck with constant temperature cold storage compartment includes a main controller 2 fixedly installed on the front outer wall of the constant temperature cold storage compartment body 1;

[0029] In this embodiment, a rotating photovoltaic mechanism is provided on the top of the constant temperature cold storage compartment body 1. The constant temperature principle of the constant temperature cold storage compartment body 1 is as follows: a heat insulation layer is provided on the inner wall of the compartment, and a cold storage plate is provided in the heat insulation layer. The cold storage plate is filled with phase change cold storage material, which can store cold energy when the refrigeration unit is working and release cold energy when needed to maintain the constant temperature in the compartment. A temperature sensor is also provided in the compartment. The temperature sensor is connected to the main controller 2. The main controller 2 intelligently controls the operation of the refrigeration unit and the release of cold energy from the cold storage plate according to the temperature signal detected by the temperature sensor. The constant temperature principle inside the refrigerated truck compartment is a mature existing technology, and this embodiment will not elaborate on it further.

[0030] Specifically, the rotating photovoltaic mechanism includes a rotating drive assembly, a fixed cover 3 fixedly connected to the top outer wall of the constant temperature cold storage compartment 1, a rotating shaft 4 rotatably mounted on the top of the fixed cover 3, a rotating seat 5 welded to the top outer wall of the rotating shaft 4, a photovoltaic bracket 6 fixedly connected to the top outer wall of the rotating seat 5 and inclined, a photovoltaic panel 7 fixedly mounted on the top inclined outer wall of the photovoltaic bracket 6, and a light sensor 8 fixedly mounted on the upper outer wall of the photovoltaic bracket 6.

[0031] Furthermore, a reciprocating dust removal mechanism is provided on the top inclined surface of the photovoltaic bracket 6. The reciprocating dust removal mechanism includes a lead screw 12, a reciprocating slider 13 threadedly connected to the lead screw 12, a dust removal brush 14 fixedly connected to the top outer wall of the reciprocating slider 13, and a servo motor 15 fixedly connected to the lower outer wall of the photovoltaic bracket 6 through a motor base.

[0032] Furthermore, the rotary drive assembly includes a drive motor 9 fixedly mounted on the side wall of the fixed cover 3, a driving bevel gear 10 fixedly mounted on the output shaft of the drive motor 9, and a driven bevel gear 11 fixedly mounted on the bottom end of the rotary shaft 4. The output shaft of the drive motor 9 passes through one side of the fixed cover 3, and the driving bevel gear 10 and the driven bevel gear 11 mesh with each other. This facilitates the rotation of the photovoltaic panel 7, making it easier for the photovoltaic panel 7 to move towards the direction of higher light intensity, which is beneficial to improving the solar energy conversion rate.

[0033] Furthermore, two bearing seats are symmetrically fixed on the outer wall of the top inclined surface of the photovoltaic bracket 6. The lead screw 12 is rotatably installed between the two bearing seats. The output shaft of the servo motor 15 is coaxially fixedly connected to the bottom end of the lead screw 12 through a coupling. This facilitates the servo motor 15 to drive the lead screw 12 to rotate stably between the two bearing seats.

[0034] Furthermore, the bottom of the cleaning brush 14 is provided with a bristle structure, which contacts the top surface of the photovoltaic panel 7. In this way, the bristle structure at the bottom of the cleaning brush 14 moves back and forth on the surface of the photovoltaic panel 7, which can effectively remove the dust attached to the surface of the photovoltaic panel 7, which is beneficial to improving the power generation effect of the photovoltaic panel 7 and helping to extend the service life of the photovoltaic panel 7.

[0035] Furthermore, a guide rail 16 is fixedly installed on the outer wall of the top inclined surface of the photovoltaic bracket 6. The guide rail 16 is slidably connected to the reciprocating slider 13. In this way, the guide rail 16 limits the reciprocating slider 13 which is threadedly connected to the lead screw 12, thus ensuring the stability of the linear motion of the reciprocating slider 13.

[0036] In addition, the light sensor 8 and the drive motor 9 are electrically connected to the main controller 2. To ensure that the light sensor 8, photovoltaic panel 7 and servo motor 15 are powered normally in the rotating state, an electric slip ring can be installed on the rotating shaft 4.

[0037] In addition, to ensure the integrity of photovoltaic power generation, besides photovoltaic panel 7, there are also batteries, inverters, charge and discharge controllers and voltage regulators, etc. Photovoltaic power generation is also a mature existing technology, and this embodiment will not elaborate on it further.

[0038] The working principle of this embodiment is as follows: First, the light sensor 8 detects the light intensity of the area facing the photovoltaic panel 7 in real time and feeds the signal back to the main controller 2. When the light sensor 8 detects that the light intensity is insufficient, the main controller 2 will control the drive motor 9 to work. At this time, the drive motor 9 drives the active bevel gear 10 to rotate. Subsequently, the driven bevel gear 11 meshing with the active bevel gear 10 will drive the photovoltaic panel 7 above the rotating shaft 4 to rotate flexibly, so that the photovoltaic panel 7 can move towards the direction with higher light intensity, which is beneficial to improving the conversion rate of solar energy.

[0039] Secondly, when dust removal is required, the servo motor 15 drives the lead screw 12 to rotate. Then, under the guidance of the guide rail 16, the reciprocating slider 13, which is threadedly connected to the lead screw 12, will drive the dust removal brush 14 to reciprocate on the surface of the photovoltaic panel 7. This can effectively remove the dust attached to the surface of the photovoltaic panel 7, which is beneficial to improving the power generation effect of the photovoltaic panel 7 and helping to extend the service life of the photovoltaic panel 7.

[0040] Example 2, refer to Figure 1 and Figure 5-6This embodiment is an optimization based on embodiment 1. Specifically, the top of the constant temperature cold storage compartment body 1 is also provided with an active odor dissipation mechanism.

[0041] More specifically, the active odor dissipation mechanism includes an exhaust pipe 17 fixedly connected to the top of the constant temperature cold storage compartment 1, a purification box 18 fixedly connected to the top of the exhaust pipe 17, an exhaust fan 19 fixedly installed on the outer wall of the top of the purification box 18, an exhaust solenoid valve 20 installed in the exhaust pipe 17, and a detachable purification component installed on the purification box 18.

[0042] Furthermore, the top of the purification box 18 is provided with an exhaust port, and the exhaust solenoid valve 20 and the exhaust fan 19 are both electrically connected to the main controller 2.

[0043] Furthermore, the detachable purification component includes an insert plate 21 inserted into the purification box 18, an activated carbon filter element 22 fixedly embedded in the insert plate 21, a limiting iron plate 23 fixedly connected to the side wall of the insert plate 21, and two permanent magnets 24 fixedly embedded on one side of the purification box 18. The limiting iron plate 23 is fixedly attracted to the two permanent magnets 24. A handle is welded to the side wall of the limiting iron plate 23, so that the insert plate 21 can be easily pulled out periodically to replace the activated carbon filter element 22 by magnetic attraction.

[0044] The working principle of this embodiment is as follows: The main controller 2 controls the exhaust solenoid valve 20 and the exhaust fan 19 to open together. At this time, the exhaust fan 19 will actively discharge the air in the constant temperature cold storage compartment 1 to the outside. During the active discharge process, the air will enter the purification box 18 from the exhaust pipe 17. Under the full adsorption and purification of the activated carbon filter element 22, the odor in the air can be effectively removed, which facilitates active deodorization after the refrigerated truck compartment is unloaded, thus improving the deodorization efficiency.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
