A gas monitoring device for refrigerated containers

Abstract

This utility model discloses a gas monitoring device for a refrigerated container, including a refrigerated container body. A door is rotatably connected to the outer wall of the refrigerated container body, and a water storage tank is fixedly connected to the top of the refrigerated container body. A water pump is fixedly connected to the outer wall of the water storage tank. A humidification mechanism is set inside the refrigerated container body. A motor drives a half-tooth gear to rotate. Since the half-tooth gear meshes with a rack, the rack moves, causing a slide rod to move inside a slide groove. The slide rod moves, causing a connecting arm to move, which in turn causes a squeezing rod to squeeze an atomizing nozzle, causing the atomizing nozzle to deflect. When the atomizing nozzle deflects, it squeezes a force rod, which in turn squeezes a spring. When the half-tooth gear disengages, the spring, which is in a squeezed state, is not affected by external force and uses its own elasticity to drive the squeezing rod to return to its original position, further causing the atomizing nozzle to swing, thereby comprehensively cooling and humidifying fruits and vegetables.

Description

Technical Field

[0001] This utility model relates to the field of refrigerated container technology, specifically a gas monitoring device for refrigerated containers. Background Technology

[0002] With the continuous improvement of global logistics capabilities, people's demand for fruits and vegetables produced in different regions around the world is also constantly increasing. In order to ensure the freshness of fruits and vegetables, they are generally harvested and transported before they are fully ripe. After arriving at their destination, they are ripened. In order to extend the shelf life, the temperature inside the transport container is lowered to inhibit the respiration of the fruits and vegetables stored in the container.

[0003] While existing refrigerated containers can achieve the effect of preservation, they can also accelerate the ripening of fruits and vegetables during transportation when the internal temperature rises, leading to spoilage. Furthermore, it is inconvenient for staff to monitor the gas concentration inside the refrigerated container. Utility Model Content

[0004] The purpose of this invention is to provide a gas monitoring device for food storage containers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas monitoring device for a refrigerated container, comprising a refrigerated container body, a door rotatably connected to the outer wall of the refrigerated container body, a water storage tank fixedly connected to the top of the refrigerated container body, a water pump fixedly connected to the outer wall of the water storage tank, a connecting corrugated pipe fixedly connected to the outer wall of the water pump, an atomizing nozzle fixedly connected to the bottom end of the connecting corrugated pipe, and a humidification mechanism provided inside the refrigerated container body.

[0006] As a further preferred embodiment of this technical solution, a fixing rod is fixedly connected to the inner wall of the main body of the refrigerated container, a spring is fixedly connected to the inner wall of the fixing rod, and a force-bearing rod is fixedly connected to the end of the spring away from the fixing rod.

[0007] As a further preferred embodiment of this technical solution, the inner wall of the main body of the refrigerated container is fixedly connected to an outer shell, the inner wall of the outer shell is fixedly connected to a motor, the outer wall of the motor is fixedly connected to a half-tooth gear, and the inner wall of the outer shell is provided with a sliding groove.

[0008] As a further preferred embodiment of this technical solution, a slide rod is slidably connected to the inner wall of the slide groove, a rack is fixedly connected to one side of the slide rod, a connecting arm is fixedly connected to the other side of the slide rod, and a pressing rod is fixedly connected to the outer wall of the connecting arm.

[0009] As a further preferred embodiment of this technical solution, the interior of the refrigerated container is equipped with a gas monitoring mechanism, which includes a gas concentration detector.

[0010] As a further preferred embodiment of this technical solution, a protrusion is fixedly connected to the top of the interior of the refrigerated container body, an air inlet is provided on the inner wall of the protrusion, and a probe is fixedly connected to the bottom of the gas concentration detector.

[0011] As a further preferred embodiment of this technical solution, a piston is slidably connected to the inner wall of the protrusion, and a second spring is fixedly connected to the bottom end of the piston. The end of the second spring away from the piston is fixedly connected to the inner bottom end of the protrusion.

[0012] This utility model provides a gas monitoring device for food storage containers, which has the following beneficial effects:

[0013] (1) This utility model uses a motor to drive a half-tooth gear to rotate. Since the half-tooth gear meshes with the rack, the rack moves and drives the slide rod to move inside the slide groove. The slide rod moves and drives the connecting arm to move, which in turn drives the extrusion rod to extrude the atomizing nozzle, causing the atomizing nozzle to deflect. When the atomizing nozzle deflects, it extrudes the force rod, which in turn extrudes the spring. When the half-tooth gear disengages, the spring in the extrusion state is not affected by external force and relies on its own elasticity to drive the extrusion rod to reset, which further drives the atomizing nozzle to swing, thereby comprehensively cooling and moisturizing fruits and vegetables.

[0014] (2) In this invention, a gas concentration detector is inserted into the inside of the protrusion. The gas concentration detector drives the probe to be inserted into the inside of the protrusion. The probe squeezes the piston. The piston moves inside the protrusion and squeezes the second spring until the piston moves to the bottom of the air inlet. At this time, the gas inside the main body of the refrigerated container enters the inside of the protrusion. The gas concentration is monitored by the gas concentration detector.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a gas monitoring device for a refrigerated container includes a refrigerated container body 1, a door 2 rotatably connected to the outer wall of the refrigerated container body 1, a water tank 3 fixedly connected to the top of the refrigerated container body 1, a water pump 4 fixedly connected to the outer wall of the water tank 3, a connecting corrugated pipe 5 fixedly connected to the outer wall of the water pump 4, an atomizing nozzle 6 fixedly connected to the bottom end of the connecting corrugated pipe 5, and a humidification mechanism 7 provided inside the refrigerated container body 1.

[0022] Among them, a fixing rod 71 is fixedly connected to the inner wall of the main body 1 of the refrigerated container, a spring 72 is fixedly connected to the inner wall of the fixing rod 71, and a force-bearing rod 73 is fixedly connected to the end of the spring 72 away from the fixing rod 71.

[0023] When the force-bearing rod 73 is compressed, it will move inside the fixed rod 71.

[0024] The inner wall of the main body 1 of the refrigerated container is fixedly connected to the outer shell 74, the inner wall of the outer shell 74 is fixedly connected to the motor 75, the outer wall of the motor 75 is fixedly connected to the half-tooth gear 76, and the inner wall of the outer shell 74 is provided with a sliding groove 77.

[0025] The half-tooth gear 76 meshes with the rack 79, and the rack 79 moves when the half-tooth gear 76 rotates.

[0026] The inner wall of the slide groove 77 is slidably connected to a slide rod 78, a rack 79 is fixedly connected to one side of the slide rod 78, a connecting arm 710 is fixedly connected to the other side of the slide rod 78, and a pressing rod 711 is fixedly connected to the outer wall of the connecting arm 710.

[0027] The rack 79 moves, which in turn drives the slide bar 78 to move inside the slide groove 77.

[0028] The interior of the refrigerated container 1 is equipped with a gas monitoring device 8, which includes a gas concentration detector 81.

[0029] The gas monitoring device 8 can quickly monitor the gas concentration inside the main body 1 of the refrigerated container according to the usage requirements.

[0030] Among them, a protrusion 82 is fixedly connected to the top of the interior of the main body 1 of the refrigerated container, an air inlet 83 is opened on the inner wall of the protrusion 82, and a probe 86 is fixedly connected to the bottom of the gas concentration detector 81.

[0031] Through the air inlet 83, the gas inside the main body 1 of the refrigerated container can enter the interior of the protrusion 82.

[0032] The inner wall of the protrusion 82 is slidably connected to a piston 85, and the bottom end of the piston 85 is fixedly connected to a second spring 84. The end of the second spring 84 away from the piston 85 is fixedly connected to the inner bottom end of the protrusion 82.

[0033] Piston 85 is compressed and moves below air inlet 83, causing probe 86 to come into contact with gas.

[0034] This utility model provides a gas monitoring device for a fresh-keeping container. The specific working principle is as follows: When it is necessary to spray water to cool and moisturize fruits and vegetables, the water pump 4 is turned on. The water pump 4 delivers water from the water storage tank 3 to the atomizing nozzle 6 through the connecting corrugated pipe 5. The atomizing nozzle 6 then atomizes the water and sprays it onto the fruits and vegetables. The motor 75 is turned on, driving the half-tooth gear 76 to rotate. Since the half-tooth gear 76 meshes with the rack 79, the movement of the rack 79 causes the slide rod 78 to move inside the slide groove 77. The movement of the slide rod 78 causes the connecting arm 710 to move, which in turn causes the extrusion rod 711 to extrude force on the atomizing nozzle 6, causing the atomizing nozzle 6 to deviate. When the atomizing nozzle 6 deviates, it extrudes force on the force rod 73, which in turn extrudes force on the spring 72. When the half-gear 76 disengages, the spring 72, which is under compression, is not affected by external force and drives the compression rod 711 to reset by its own elasticity. This further drives the atomizing nozzle 6 to swing, thereby comprehensively cooling and moisturizing the fruits and vegetables. When it is necessary to monitor the gas concentration inside the main body 1 of the refrigerated container, the gas concentration detector 81 is inserted into the inside of the protrusion 82. The gas concentration detector 81 drives the probe 86 to be inserted into the inside of the protrusion 82. The probe 86 compresses the piston 85. The piston 85 is compressed and moves inside the protrusion 82 and compresses the second spring 84 until the piston 85 moves to the bottom of the air inlet 83. At this time, the gas inside the main body 1 of the refrigerated container enters the inside of the protrusion 82, and the gas concentration is monitored by the gas concentration detector 81.
