[0002] Agricultural products are items produced in agriculture, such as sorghum, rice, peanuts, corn, wheat, vegetables, and local specialties in various regions; China is a large agricultural country, and agriculture is related to the national economy and people's livelihood and is the pillar industry of the national economy; in 1995, the total agricultural output value in China exceeded the trillion-yuan mark; since the beginning of the 21st century, the total agricultural output value has increased by more than 10% annually on average and reached 4,771.2 billion yuan in 2011; along with the steady growth of the total agricultural output value, the level of agricultural production and operation in China has risen steadily, and the living standards of farmers have increased steadily; while the industrialization of agriculture has developed rapidly, the scale of the agricultural product processing industry in China has shown a rapid expansion trend, the number of processing enterprises has been increasing, and the operating efficiency is good; while the output of agricultural products has expanded rapidly, the preservation and transportation of agricultural products have always been issues of concern in the industry.

[0003] When using a cold storage to store fresh agricultural products, due to the respiration of the agricultural products themselves, a large amount of carbon dioxide and heat are released. Although the existing cold storage is equipped with a ventilation and heat dissipation system, during the use process, overall ventilation and heat dissipation are often carried out. In fact, there is often a situation where heat is concentrated in some areas inside the cold storage (referred to as heat accumulation). For this local heat concentration situation, it is also necessary to discharge the heat in time to avoid affecting the preservation of agricultural products. However, the traditional ventilation and heat dissipation system cannot dissipate heat targeted, resulting in serious energy waste. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the heat dissipation system in the existing cold storage cannot dissipate heat targeted for local areas inside the cold storage, and to propose a heat dissipation system for scattered heat accumulation in a fresh-keeping cold storage for agricultural products.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Furthermore, a folding baffle for adjusting the opening or closing of the ventilation window is arranged inside the ventilation window.

[0008] Further, the folding baffle includes a rotating shaft and a baffle. Both ends of the rotating shaft are rotatably connected to the side walls of the ventilation window. A baffle is provided in the middle of the rotating shaft. A plurality of the rotating shafts are arranged at intervals along the radial direction of the rotating shaft within the ventilation window.

[0009] Further, one end of one of the rotating shafts is connected to the working end of the driving source;

[0010] A plurality of the baffles are connected together by connecting rods.

[0011] Further, a connecting ring is provided between the baffle and the connecting rod. The connecting ring penetrates through the baffle and the connecting rod, and the connecting ring is movably connected to the baffle and the connecting rod.

[0012] Further, the ventilation window includes a straight cylinder channel and a flared opening. The temperature sensor is installed at the bottom of the flared opening.

[0013] Further, a wind guiding plate is provided inside the flared opening.

[0014] Compared with the prior art, the present utility model provides an agricultural product fresh-keeping cold storage heat dissipation system, which has the following beneficial effects:

[0015] When the agricultural product fresh-keeping cold storage heat dissipation system of the present utility model is in use, the system is installed in the cold storage. When the temperature sensor detects that the temperature exceeds the predetermined requirement, the ventilation window corresponding to the temperature sensor is opened, and ventilation and heat dissipation are carried out for the accumulated heat in the local area detected by the temperature sensor, with higher heat dissipation efficiency and more timely heat dissipation effect.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0028] Referring to Figure 1-8 , an agricultural product fresh-keeping cold storage heat dissipation system of the present utility model includes a ventilation main pipe 1, and the ventilation main pipe 1 is connected to an external fan for exhausting air from the inside of the cold storage to the outside.

[0029] A ventilation sub-pipe 2 is connected to the ventilation main pipe 1. During use, according to the internal layout of the cold storage, the ventilation sub-pipe 2 is extended as needed and arranged approximately evenly throughout the cold storage. A plurality of ventilation sub-pipes 2 are evenly arranged on the inner top of the cold storage. A plurality of individually openable and closable ventilation windows 3 are evenly installed on the ventilation sub-pipes 2. The ventilation windows 3 are also arranged evenly according to the overall unevenness inside the cold storage, so that the distance between adjacent two ventilation windows 3 is approximately the same. A temperature sensor 4 is installed on the ventilation window 3. By connecting the temperature sensor 4 to an external controller, when the temperature sensor 4 detects that the temperature value exceeds the predetermined requirement, the controller controls and adjusts the start of the fan connected to the ventilation main pipe 1, and at the same time, the ventilation window 3 approximately corresponding to the temperature sensor 4 discharges the hot air and accumulated heat near the ventilation window 3.

[0030] A folding baffle 6 for adjusting the opening or closing of the ventilation window 3 is installed inside the ventilation window 3. According to needs, when heat accumulation occurs near a certain ventilation window 3, the folding baffle 6 inside the ventilation window 3 is controlled to open to discharge the targeted accumulated heat.

[0031] Specifically, the folding baffle 6 includes a rotating shaft 601 and a baffle 602. Both ends of the rotating shaft 601 are rotatably connected to the side walls of the ventilation window 3. The baffle 602 is fixedly connected to the bottom of the middle of the rotating shaft 601. The length of the baffle 602 is slightly smaller than the inner width of the straight-cylindrical channel 301. Multiple rotating shafts 601 are arranged in the ventilation window 3 at intervals along the radial direction of the rotating shaft 601. When the baffle 602 rotates around the rotating shaft 601, the multiple baffles 602 form a flat plate, which separates the upper and lower connections of the straight-cylindrical channel 301 from the middle, and is used to close the ventilation window 3.

[0032] One end of one of the rotating shafts 601 is connected to the working end of the driving source 5. The driving source 5 can be a servo motor. The driving source 5 drives the rotating shaft 601 to rotate, and further drives the remaining rotating shafts 601 and the baffle 602 to rotate, so as to open or close the baffle 602 in a ventilation window 3.

[0033] The plurality of baffles 602 are connected together by a connecting rod 604 , so that when one of the baffles 602 is rotated, the connecting rod 604 can drive the other baffles 602 to rotate synchronously to perform an opening or closing action.

[0034] A connecting ring 603 is installed between the baffle 602 and the connecting rod 604. The connecting ring 603 passes through the baffle 602 and the connecting rod 604, and is movably connected to the baffle 602 and the connecting rod 604. Specifically, through holes are opened at the lower part of the baffle 602 and the top of the connecting rod 604. The shape of the through hole corresponds to the connecting ring 603, and the inner diameter of the through hole is larger than the outer diameter of the connecting ring 603. The connecting ring 603 is penetrated in the through hole so that the connecting ring 603 can rotate freely in the through hole. Multiple baffles 602 and the connecting rod 604 are connected together through the connecting ring 603.

[0035] The ventilation window 3 includes a straight channel 301 and a bell mouth 302, and the temperature sensor 4 is installed at the bottom of the bell mouth 302. In the present system, the temperature sensor 4 and the ventilation window 3 are evenly arranged inside the cold storage, and each temperature sensor 4 detects an area where it is located. All the temperature sensors 4 monitor the temperature changes in various places in the cold storage, and are used to detect whether there is heat accumulation in various areas of the cold storage.

[0036] The bell mouth 302 is internally provided with an air guide plate 7. Specifically, the air guide plate 7 includes a horizontal plate 701 and a vertical plate 702. Figure 6, the horizontal plates 701 and the vertical plates 702 intersect with each other to form a matrix distribution. Among them, several middle horizontal plates 701 and vertical plates 702 are arranged vertically, while the horizontal plates 701 and vertical plates 702 on both sides form a certain angle with the middle horizontal plates 701 and vertical plates 702, so that the bottoms of the horizontal plates 701 and vertical plates 702 on both sides are inclined outward, and the inclination angle corresponds to the side wall of the bell mouth 302, which is convenient for sucking the air outside the lower part of the ventilation window 3 when sucking the air inside the cold storage.

[0037] Working principle: When in use, install this system in the cold storage. The ventilation sub-pipes 2 are arranged at the top inside the cold storage. The temperature sensors 4 are used to detect the temperature changes in each area above the inside of the cold storage in real time. When the temperature sensor 4 detects that the temperature in its own area exceeds the predetermined requirement, start the drive source 5. The drive source 5 drives one of the rotating shafts 601 to rotate. This rotating shaft 601 drives the corresponding baffle 602 to rotate. This baffle 602 drives other baffles 602 to rotate synchronously through the connecting rod 604, opens the ventilation window 3 corresponding to this temperature sensor 4, and sucks the heat-accumulated air in the area below this ventilation window 3. This part of the heat-accumulated air enters the ventilation sub-pipe 2 through the ventilation window 3, then enters the ventilation main pipe 1, and finally is discharged from the cold storage.
