Description

Technical Field

[0001] The utility model belongs to the technical field of detection doors, in particular to a special safety electric grain condition detection door for low-temperature grain storage. Background Art

[0002] In today's grain warehouses, insect infestations can occur during storage. Therefore, after grain enters the warehouse, a circulating fumigation method is commonly used to control insects. After application, sampling is commonly performed at the fumigation inspection port to test the drug concentration and oxygen content within the warehouse to ensure safe entry for workers, or to analyze the grain condition monitoring system. However, this sampling method is cumbersome and unintuitive, and the test results cannot be transmitted in real time or may be erroneous. If the drug concentration within the warehouse does not meet the standard for worker entry, safety accidents such as poisoning or suffocation may occur.

[0003] The circulating fumigation method will produce phosphine gas, which has an insecticidal effect. However, the diffusion rate of phosphine gas slows down in a low-temperature environment, and the generation efficiency of phosphine gas will accelerate in an environment with high humidity.

[0004] According to the applicant's search, the authorized patent with announcement number CN209621003U mentioned a toxic gas detection door, which belongs to the field of door technology. This detection door includes a cold storage door, a detection mechanism and a driving mechanism. The detection mechanism includes two detectors and an alarm. The detector is installed on the inside of the cold storage door, and the alarm is installed on the outer wall of the cold storage. When toxic gas appears in the cold storage, the detector detects the toxic gas at the first time, and the alarm sounds an alarm to remind the management personnel; the driving mechanism includes a gear, a rack and a motor. The gear is fixedly connected to the motor, and the rack is fixedly connected to the upper end of the cold storage door. The gear is meshed with the rack. When toxic gas is detected, the signal sending module sends a signal to the signal receiving module, drives the motor, drives the gear to rotate, drives the rack to move, thereby drives the cold storage door to move, closes the cold storage door tightly, prevents the gas in the cold storage from overflowing, and prevents the management personnel from inhaling toxic gas, realizes the detection of toxic gas in the cold storage and automatically closes the cold storage door.

[0005] In the existing technology represented by the above patent, there are at least the following problems: the detection door can only detect toxic gases, and cannot detect the oxygen content and temperature and humidity in the warehouse. Not only toxic gases, but also insufficient oxygen content in the warehouse or toxic gases caused by oxygen temperature and humidity accumulating in local areas, resulting in incorrect detection, can also lead to safety accidents.

[0027] Examples, such as Figures 1 to 5 As shown:

[0028] To solve the above technical problems, the present embodiment provides a safe electric grain condition detection door specially designed for low-temperature grain storage, comprising: a detection door 1; a detection structure 2, comprising a phosphine sensor 21 and an oxygen temperature and humidity sensor 22, wherein the detection structure 2 is mounted on the inner side of the detection door 1 and is used to detect the phosphine gas concentration and the oxygen temperature and humidity within the detection door 1; a sealing airbag 3, wherein a mounting groove 31 is formed along a side wall of the detection door 1, and the sealing airbag 3 is mounted in the mounting groove 31; and a control structure 4, mounted on the outer side of the detection door 1 and communicatively connected to the detection structure 2 and the sealing airbag 3, respectively. Concentration signals received by the phosphine sensor 21 and the oxygen temperature and humidity sensor 22 are fed back to the control structure 4, and the phosphine gas concentration and the oxygen temperature and humidity within the detection door 1 are displayed in real time on the control structure 4. When the phosphine gas concentration and oxygen content detected by the detection structure 2 meet the standards, the sealing airbag 3 is opened by the control structure 4.

[0029] The detection structure 2 is installed on the wall inside the warehouse on the inside of the detection door 1, and the control structure 4 is installed on the outside of the detection door 1, on the outer wall corresponding to the position of the detection structure 2, to facilitate the connection of the lines between the detection structure 2 and the control structure 4. The sealing airbag 3 is installed on the outside of the detection door 1. The phosphine gas concentration and oxygen temperature and humidity in the warehouse can be detected in real time. When the phosphine gas concentration in the warehouse does not meet the national safety standards, the staff cannot open the detection door 1 to enter the warehouse, so as to ensure the safety of the staff. Figure 4 、 Figure 5As shown, the function of the sealing airbag 3 is to inflate the airbag when the detection structure 2 sends a signal to close it. The inflated sealing airbag 3 allows the detection door 1 to fit tightly against the door frame, forming an effective sealing barrier to prevent leakage of drugs or phosphine gas within the warehouse and to prevent contamination outside the warehouse. When the detection structure 2 sends a signal to open it, the airbag is deflated. The deflated sealing airbag 3 no longer tightly fits the detection door 1 against the door frame, facilitating opening of the detection door 1. The display screen of the detection structure 4 includes a first display area, a second display area, a third display area, a fourth display area, and a password input area. The first display area displays the phosphine gas concentration within the warehouse, the second display area displays the oxygen content within the warehouse, the third display area displays the temperature within the warehouse, and the fourth display area displays the humidity within the warehouse. The password input area is used by staff to enter a key to enter the warehouse.

[0030] Furthermore, it also includes: a detection door lock 32, which is connected to the control structure 4, and the detection door lock 32 is opened by inputting the corresponding key through the control structure 4; a sealed door handle 33, which is installed on the detection door 1, and the sealed door handle 33 is installed one at the upper and bottom sides of the detection door 1.

[0031] Among them, the detection door lock is installed in the middle position of the opening and closing direction of the detection door 1 and is connected to the control structure 4. When the staff does not input the key from the control structure 4, the detection door lock 32 cannot be opened. The sealed door handle is installed at the upper and bottom parts of the opening and closing direction of the detection door 1 to maintain the airtightness of the detection door 1, improve the sealing performance of the detection door 1, and ensure that the leakage of gas, liquid or other substances can be effectively prevented when it is closed.

[0032] Furthermore, it also includes: an alarm 5 connected to the control structure 4, which is used to give an alarm to the staff inside the detection door 1 in an emergency.

[0033] Among them, the alarm 5 is installed on the outside of the detection door 1, and the alarm 5 is installed on one side of the control structure 4 and is communicated with the control structure 4. When the concentration of phosphine gas in the warehouse does not meet the national safety standards and there is a special situation where it is necessary to enter the warehouse, the administrator key is entered to open the detection door 1 lock and enter the warehouse. At the same time, the alarm 5 will continue to alarm.

[0034] Furthermore, it also includes: an oxygen content detection sensor 6, which is communicatively connected to the control structure 4 and is used to detect the oxygen content in the detection door 1 in real time.

[0035] Among them, the oxygen content detection sensor 6 is installed on the inner side of the detection door 1 and on the wall inside the warehouse to detect the oxygen content information in the warehouse in real time to ensure the safety of the staff in the warehouse. At the same time, if it meets the standards, the password input module can be used to input the key to open the detection door 1.

[0036] In summary, the phosphine gas concentration, oxygen content, temperature and humidity in the detection door 1 are detected by the detection structure 2 and the oxygen content detection sensor 6, and displayed in real time on the control structure 4. When the phosphine gas concentration and oxygen content in the detection door 1 meet the national safety standards, the key can be entered on the control structure 4 to open the sealed airbag 3 and the detection door lock 32, and then the detection door 1 is opened. In special circumstances, the administrator key can be entered on the control structure 4 to open the sealed airbag 3 and the detection door lock 32, and then the detection door 1 is opened. At the same time, the alarm 5 will continuously sound an alarm prompt.
