Description
Technical Field
[0001] This utility model belongs to the technical field of grain storage inspection equipment, and specifically relates to a fumigation film inspection device that facilitates entry into the warehouse. Background Technology
[0002] In grain storage, fumigation is a key technical means to control pests and ensure the safety of stored grain. Fumigation agents such as phosphine are commonly used, and they are widely applied in various fumigation processes due to their high efficiency and economy. However, because fumigants are highly toxic and easily diffused, the fumigation environment must be strictly sealed to prevent leakage that could cause environmental pollution and personal injury. Simultaneously, the fumigant concentration must be maintained within the enclosure to achieve thorough pest control. Grain depots typically use airtight enclosures made of materials such as polyethylene to seal the grain piles, creating a sealed space. To monitor the concentration of fumigant gas within the enclosure in real time, detection ports are usually installed. Sealing tools are then glued to these ports to prevent leakage and improve the reliability of fumigation. However, this glued installation method increases the difficulty of disassembly and adjustment, makes the material non-reusable, and can damage the film, increasing the risk of leakage and posing safety hazards. Utility Model Content
[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a fumigation film detection device. The technical problem this invention aims to solve is: how to prevent fumigant leakage and reduce safety risks.
[0004] The objective of this utility model can be achieved through the following technical solution: A film detection device for fumigation, comprising a tent and a detection valve, wherein the tent has a detection port connected to the outside, and the detection port is provided with a mounting base, the mounting base and the detection valve are connected through a detection tube, characterized in that the mounting base comprises a base body, a base cover and a flexible sealing gasket, the sealing gasket has an L-shaped cross section and is fitted onto one end of the base cover, and the sealing gasket is located between the base body and the base cover, when one end of the base cover passes through the sealing gasket and is threadedly connected to the base body, the mounting base is clamped and fixed to the detection port of the tent by the sealing gasket and the base body.
[0005] This application, based on the existing detection port on the fumigation tent, avoids leakage of fumigant vaporization in non-detection states by connecting a detection valve to the detection port. This ensures detection and fumigation effects while reducing safety hazards. Furthermore, this application incorporates a flexible sealing gasket with an L-shaped cross-section inside the mounting base installed on the detection port. The cover of the mounting base passes through the hollow area of the sealing gasket and is threaded to the base body. By designing the connection between the base body and the cover inside the fumigation tent, leakage caused by the connection being located on the side of the tent is avoided. The base body and cover are then threaded together, pushing the two ends of the sealing gasket located between them to fit tightly against the base body and the cover respectively. By compressing the sealing gasket, it deforms, clamping the tent between the sealing gasket and the base body, further improving the sealing effect and preventing leakage of vaporized fumigant from its side.
[0006] In the aforementioned fumigation film detection device, the end of the seat cover fitted with a sealing gasket is a connecting part. The threaded portion of the connecting part passes through the detection port and the sealing gasket, thus threading the seat cover to the seat body. By designing the connection between the seat body and the seat cover to be inside the tent by passing the connecting part through the detection port and the sealing gasket, and by fitting a sealing gasket on the outer side, the leakage of fumigant vaporization is further prevented.
[0007] In the aforementioned fumigation membrane inspection device, the thread on the threaded portion is a pipe thread. By connecting the seat body and the seat cover via a pipe thread, the sealing effect is further improved.
[0008] In the above-mentioned fumigation film detection device, the detection valve includes a valve body and a switch handle. The valve body is provided with a flexible valve core, which is directly connected to the switch handle.
[0009] In the above-mentioned fumigation film detection device, both the mounting base and the detection valve are equipped with clamps, which are used to fix the detection tube inside the mounting base and the detection valve.
[0010] In the above-mentioned fumigation film detection device, one end of the detection valve is connected to the mounting base through a detection tube, and the other end is connected to the detection equipment through a detection tube.
[0011] Compared with the prior art, the present invention has the following advantages: 1. Based on the existing fumigation film detection device, this application makes a connection between the seat cover and the cover inside the tent by passing the connecting part on the cover through the detection port and the sealing gasket and connecting it to the seat body by thread. This reduces the risk of fumigant leakage from the connection between the two. Furthermore, by setting an L-shaped sealing gasket between the two and using the threaded connection to compress the sealing gasket, it deforms and clamps the tent between the sealing gasket and the seat body, further preventing leakage from the side and improving the sealing effect.

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0014] like Figure 1 and Figure 2 As shown, the fumigation film detection device of this application includes a tent and a detection device. The detection device includes a mounting base 2 and a detection valve 3. The detection valve 3 includes a valve body 3a and a switch handle 3b located on the top of the valve body 3a. One end of the detection valve 3 is connected to the mounting base 2 through a detection tube 4, and the other end is connected to the detection equipment through the detection tube 4. The detection device is clamped and fixed to the side of the tent 1 by the mounting base 2. The mounting base 2 includes a cover 2b and a body 2a. The body 2a is located inside the tent 1, and the cover 2b is located outside the tent 1. The two are clamped and fixed to the side of the tent 1.
[0015] like Figure 3As shown, the detection device includes a mounting base 2, a detection valve 3, and a detection tube 4. The detection tube 4 is used to connect the mounting base 2 and the detection valve 3, and can also be used to connect the detection valve 3 to external detection equipment. The detection valve 3 has a flexible valve core 3a1 inside its valve body 3a. One end of the switch handle 3b passes through the valve body 3a and is connected to the flexible valve core 3a1. The mounting base 2 includes a seat cover 2b, a seat body 2a, and an annular sealing gasket 2c. The seat cover 2b is connected to the valve body 3a through the detection tube 4. The sealing gasket 2c is located between the seat cover 2b and the seat body 2a. The seat body 2a is located inside the tent 1, and the seat cover 2b is located outside the tent 1. The sealing gasket 2c has an L-shaped cross-section. A detection port 1a is opened on the side of the tent 1. One end of the sealing gasket 2c and the seat cover 2b passes through the detection port 1a and enters the tent 1. Both the detection valve 3 and the mounting base 2 are equipped with clamps 5. The two ends of the detection tube 4 are connected to the mounting base 2 and the detection valve 3 through clamps.
[0016] like Figure 4 As shown, one side of the cover 2b extends inward into the tent 1 to form a connecting part 2b1. One end of the connecting part 2b1 is provided with a threaded part 2b2. The sealing gasket 2c has an L-shaped cross-section, and one end of the sealing gasket 2c passes through the detection port 1a and extends into the tent 1, while the other end contacts the outer surface of the tent 1. The connecting part 2b1 on the cover 2b passes through the tent 1 and is threadedly connected to the seat body 2a. The sealing gasket 2c is sleeved on the outside of the connecting part 2b1 and is located between the seat body 2a and the cover 2b. When the user fixes the mounting base 2 onto the tent 1, the cover 2b and the seat body 2a are threadedly connected, clamping the sealing gasket 2c between the two and making the surface of the sealing gasket 2c fit tightly against the outer surface of the tent 1. This clamps the sealing gasket 2c and the seat body 2a at the detection port 1a on the side of the tent 1, thereby completing the fixation of the mounting base 2.
[0017] In summary, this application, based on the existing fumigation tent 1, uses a flexible sealing gasket 2c to clamp and fix the tent 1 in place with the seat body 2a of the mounting base 2. Compared to existing methods that use adhesive mounting base 2 or cover the detection port 1a of the tent 1 with tape to prevent leakage during use, the reliability of adhesive or tape sealing depends on the adhesive strength. Over time, there is a risk of detachment due to falling off, and it is difficult to visually determine whether the adhesion is uniform, thus easily leading to leakage of the internal fumigant. To avoid these problems, this application uses a clamping fixation method, with a clamping device between the seat body 2a and the seat cover 2b. The sealing gasket 2c is used, and the connection part 2b1 between the seat body 2a and the seat cover 2b is connected by a pipe thread to prevent the mounting seat 2 from becoming loose due to displacement of the seat body 2a and the seat cover 2b. This ensures that the detection port 1a of the tent 1 is always clamped between the sealing gasket 2c and the seat body 2a. The sealing gasket 2c is made of flexible material, which avoids damage to the outer wall of the tent 1 during installation. At the same time, it further improves the sealing effect by clamping and compressing deformation. On this basis, the connection part 2b1 is extended into the interior of the tent 1, and the sealing gasket 2c is clamped between the two, thereby preventing the fumigant from leaking from the connection point if the connection point is located outside the tent 1.
[0018] It is worth mentioning that the valve core of the detection valve 3 in this application is a flexible valve core 3a1, which performs secondary sealing on the gas flowing out of the tent 1, thereby improving the sealing effect.
