Description

Technical Field

[0001] This utility model relates to the field of grain warehouse ventilation technology, and in particular to an intelligent ventilation system based on monitoring data of the internal and external environment of the grain warehouse. Background Technology

[0002] When storing grain in a granary, it is necessary to control the ventilation time and volume according to the grain temperature and environmental conditions. Currently, intelligent ventilation systems for grain silos, which include integrated control boxes, temperature measuring cables, fans, circulating fumigation machines, and electric ventilation windows, are widely used to achieve intelligent and automated ventilation operations.

[0003] However, the existing intelligent ventilation system for grain warehouses has the following shortcomings: 1. The temperature measuring cable lacks a protective structure, and it is easily bent and deformed by the grain during the grain loading and unloading process, causing damage; 2. There is a lack of equipment outside the grain warehouse to monitor the meteorological environment, which leads to ventilation under unfavorable meteorological conditions, thus worsening the storage environment inside the grain warehouse. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems in the existing technology and provide an intelligent ventilation system based on monitoring data of the internal and external environment of grain warehouses.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] An intelligent ventilation system based on monitoring data of the internal and external environment of a grain silo includes an integrated control box, and a temperature measuring cable, a fan, a circulating fumigation machine, and an electric ventilation window connected to the integrated control box. The temperature measuring cable is equipped with a support frame to prevent it from being squeezed, bent, or deformed by the grain pile. The bottom of the support frame is installed on the ground inside the grain silo, and the top of the support frame is suspended from the silo ceiling inside the grain silo by a steel wire rope. The integrated control box is also connected to a portable weather station, which is installed on the outer wall of the grain silo.

[0007] The support frame includes multiple sections of conduit for accommodating temperature measuring cables and three sets of support ribs parallel to the central axis of the support frame. The multiple sections of conduit are fixed between the three sets of support ribs. An interval area is reserved between adjacent sections of conduit for the temperature sensor of the temperature measuring cable to contact the grain. The three sets of support ribs are arranged in a circular array with the conduit as the center.

[0008] The supporting ribs are divided into one set of integral supporting ribs and two sets of spliced ​​supporting ribs.

[0009] The conduit includes a first tube with a superior arc cross-section and a second tube with a inferior arc cross-section. A first support plate is fixed to each of the two long sides of the outer wall of the first tube, and a second support plate is fixed to each of the two long sides of the outer wall of the second tube. Each first support plate and a second support plate are connected by threaded fasteners to form a set of spliced ​​support ribs. The integrated support rib is located in the middle of the outer wall of the first tube.

[0010] Among them, a fan-shaped base plate is fixed between the bottom of the integrated support rib and the bottom of the two first support plates, and the base plate is installed on the ground inside the grain silo with expansion bolts; the top of the integrated support rib is provided with a round hole for the steel wire rope to pass through.

[0011] The length of the conduit is less than the distance between two adjacent temperature sensors on the temperature measuring cable.

[0012] The support frame is also equipped with a humidity sensor for measuring the moisture content of the grain, and the humidity sensor is connected to an integrated control box.

[0013] The beneficial effects of this utility model are: a support frame is installed in the grain warehouse, and the temperature measuring cable is installed in the support frame. The support frame supports the temperature measuring cable and prevents the temperature measuring cable from being squeezed, bent and deformed by the grain pile; a portable weather station is installed outside the grain warehouse to provide meteorological environmental monitoring data around the grain warehouse for the integrated control box, avoiding ventilation deterioration of the storage environment inside the grain warehouse under unfavorable meteorological conditions such as rainy days and humid weather.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 8 As shown, an intelligent ventilation system based on monitoring data of the internal and external environment of a grain warehouse includes an integrated control box 1, a temperature measuring cable 2, a fan 3, a circulating fumigation machine 4, and an electric ventilation window 5 connected to the integrated control box 1.

[0026] The integrated control box 1 is also connected to a portable weather station 8, which is installed on the outer wall of the grain silo. Installing the portable weather station outside the grain silo provides the integrated control box with meteorological environmental monitoring data of the surrounding environment, preventing ventilation from worsening the storage environment inside the grain silo under unfavorable weather conditions such as rain or dampness.

[0027] A support frame 6 is installed on the temperature measuring cable 2 to prevent it from being squeezed, bent, or deformed by the grain pile. The bottom of the support frame 6 is installed on the ground inside the grain silo, and the top of the support frame 6 is suspended from the ceiling of the grain silo by a steel wire rope 7. The support frame is installed in the grain silo, and the temperature measuring cable is installed in the support frame. The support frame supports the temperature measuring cable and prevents it from being squeezed, bent, or deformed by the grain pile.

[0028] The support frame 6 is made of fiberglass, which gives it the advantages of being lightweight, high-strength, and resistant to potassium acid.

[0029] The support frame 6 includes multiple conduits 61 for accommodating temperature measuring cables and three sets of support ribs 62 parallel to the central axis of the support frame 6. The multiple conduits 61 are fixed between the three sets of support ribs 62. An interval area 63 is reserved between two adjacent conduits 61 for the temperature sensor 21 of the temperature measuring cable 2 to contact the grain. The length of the conduit 61 is less than the distance between two adjacent temperature sensors 21 on the temperature measuring cable 2.

[0030] The inner diameter of conduit 61 is smaller than the diameter of temperature sensor 21, while the inner diameter of conduit 61 is larger than the diameter of the cable portion of the temperature measuring cable. This ensures that temperature sensor 21 is located in interval area 63, and that conduit 61 has space to accommodate redundant temperature measuring cables.

[0031] Three sets of support ribs 62 are arranged in a circular array around the conduit 61, improving the bending resistance of the conduit 61. The support ribs 62 consist of one set of integral support ribs 621 and two sets of spliced ​​support ribs 622.

[0032] The conduit 61 includes a first tube body 611 with a superior arc cross-section and a second tube body 612 with a inferior arc cross-section. A first support plate 6221 is fixed to each of the two long sides of the outer wall of the first tube body 611, and a second support plate 6222 is fixed to each of the two long sides of the outer wall of the second tube body 612. Each first support plate 6221 and a second support plate 6222 are connected by a threaded fastener 10 to form a set of spliced ​​support ribs 622. The integrated support ribs 621 are located in the middle of the outer wall of the first tube body 611.

[0033] An annular base plate 64 is fixed between the bottom of the integrated support rib 621 and the bottom of the two first support plates 6221. The base plate 64 is installed on the ground inside the grain silo with expansion bolts. A circular hole 6211 for the steel wire rope 7 to pass through is opened at the top of the integrated support rib 621. The end of the steel wire rope 7 away from the support frame is suspended on the top of the grain silo. The two ends of the steel wire rope 7 are locked with buckles to form a rope loop.

[0034] The support frame 6 is also equipped with a humidity sensor 9 for measuring the moisture content of the grain. The humidity sensor 9 is connected to the integrated control box 1.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
