[0002] Grain warehouses are important places for storing grain, and the gas environment inside them is crucial to the safety of grain storage. There may be excessive concentrations of carbon dioxide or excessive levels of residual fumigation gases such as phosphine in grain warehouses. These gases can not only affect the quality of grain, but also threaten the health of personnel working in the grain warehouse, and even cause safety accidents.

[0003] Among the existing technical solutions, the publication number CN220399053U discloses a grain silo gas detection device, which includes a grain silo. A hollow plate is fixedly installed on the right side of the inner wall of the grain silo, and a dust removal mechanism is provided. The dust removal mechanism includes a motor, which is fixedly installed on the top of the inner wall of the grain silo. The output end of the motor is fixedly connected to one end of a rotating rod through a coupling, and the other end of the rotating rod movably penetrates into the interior of the hollow plate.

[0004] The installation structure of the detection device is complex, and it mostly adopts fixed connection. Disassembly requires professional tools and is cumbersome, which leads to time-consuming and labor-intensive equipment maintenance, component replacement or position adjustment in the later stage, increasing maintenance costs and work difficulty. Utility Model Content

[0005] The purpose of this invention is to provide a safe gas detection device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A safety gas detection device includes a gas detection body, a control panel fixedly installed on the front side of the gas detection body, a gas collection tube fixedly installed on the bottom of the gas detection body, and an assembly plate fixedly installed on the back side of the gas detection body.

[0008] Also includes:

[0009] The mounting mechanism is located on the outside of the assembly plate and is installed by threaded connection for tight compression, enabling convenient installation.

[0010] A protective mechanism is installed at the bottom of the gas collection pipe to filter and block dust and water vapor from entering the device, thereby protecting the detection equipment.

[0011] A further improvement of the present invention is that the installation mechanism includes a fixed base and an upper baffle. One end of the upper baffle is provided with a plug hole. A threaded rod is movably sleeved inside the plug hole. The bottom of the threaded rod is fixedly installed inside the fixed base, and the top of the threaded rod is threaded with a nut.

[0012] A further improvement of this utility model is that: fixing blocks are fixedly installed on both sides of the fixing base, and fixing bolts are threadedly connected to the surface of the fixing blocks.

[0013] A further improvement of this utility model is that a pressing plate is fixedly installed at one end of the upper baffle, a friction pad is fixedly installed at the bottom of the pressing plate, and an anti-slip groove is provided at the bottom of the friction pad.

[0014] A further improvement of this utility model is that: a slide rail is fixedly installed inside the fixed base, and clamps are slidably installed at both ends of the slide rail. A buffer column is provided on the other side of the clamp, and the other end of the buffer column is fixedly installed on the inner wall of the fixed base.

[0015] A further improvement of the present invention is that the protective mechanism includes a protective sleeve and a filter screen. The inside of the protective sleeve is movably fitted onto the bottom of the gas collecting pipe. A protective side plate is fixedly installed on the outside of the protective sleeve. The bottom of the inner cavity of the protective sleeve is fixedly installed on the outside of the filter screen.

[0016] A further improvement of this utility model is that: a base is fixedly installed inside the protective sleeve, an assembly frame is detachably connected to the top of the base, and a breathable membrane is fixedly installed inside the assembly frame.

[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0018] 1. This utility model provides a safe gas detection device. By placing an assembly plate between a fixed base and an upper baffle, aligning the insertion hole at one end of the upper baffle with the threaded rod inside the fixed base, and then rotating the nut at the top of the threaded rod, the upper baffle gradually presses down as the nut tightens downwards. This causes the friction pad at the bottom of the pressing plate to press firmly against the surface of the assembly plate. Combined with the locking force of the threaded connection, this achieves a fixed installation function, preventing the device from loosening or shifting during use. When adjusting the installation position of the device, simply rotate the nut in the opposite direction to easily loosen the upper baffle and conveniently remove the device. This convenient disassembly and assembly process reduces the difficulty and cost of later maintenance, and improves the ease of use and maintenance efficiency of the device.

[0019] 2. This utility model provides a safe gas detection device. The gas first passes through a filter screen to remove dust, particles and other impurities from the air, and then passes through a breathable membrane inside the assembly frame. The breathable membrane can effectively block water vapor from entering without affecting gas flow, thus achieving dual purification of the gas and preventing impurities from adhering to the detection element or causing corrosion, thereby ensuring the accuracy of the detection element and extending its service life.

[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] like Figure 1-5 As shown, this utility model has the following three specific embodiments.

[0028] Example 1

[0029] This utility model provides a safe gas detection device, including a gas detection body 1, a control panel 2 fixedly installed on the front side of the gas detection body 1, a gas collection pipe 3 fixedly installed on the bottom of the gas detection body 1, and an assembly plate 5 fixedly installed on the back side of the gas detection body 1.

[0030] Also includes:

[0031] The mounting mechanism is located on the outside of the assembly plate 5 and is installed by threaded connection and tight compression for convenient installation.

[0032] The protective mechanism is located at the bottom of the gas collection pipe 3 and is used to filter and block dust and water vapor from entering the device, thus protecting the detection equipment.

[0033] like Figure 1 As shown, during installation, the mounting mechanism functions through a threaded connection. Workers pre-fix the mounting components, which are compatible with the mounting mechanism on the outside of the mounting plate 5, to the installation position. Then, the mounting plate 5 is aligned with the mounting components, and through rotation and other operations, the threaded structure of the mounting mechanism engages. The tightness of the threaded connection presses the mounting plate 5 firmly onto the mounting components, thus facilitating the installation of the gas detection body 1. The gas collection pipe 3 collects the external gas after it has been processed by the protective mechanism and delivers it to the detection element inside the gas detection body 1. After detecting the gas concentration, the detection element transmits the detected signal to the processing module inside the gas detection body 1. The processing module analyzes and processes the signal, and the data is transmitted to the control panel 2 on the front. The display screen on the control panel 2 shows this information in real time for easy viewing by workers. Furthermore, the protective mechanism at the bottom of the gas collection pipe 3 plays a crucial protective role. External gas first passes through the protective mechanism as it enters the gas collection pipe 3. The protective mechanism can filter and block dust and moisture in the air, preventing these impurities from entering the device. This effectively prevents dust from adhering to the detection elements and affecting the detection accuracy, and also prevents moisture from corroding and damaging the internal circuits and other components of the device, thus ensuring the normal operation of the detection equipment and the accuracy of the detection results.

[0034] Example 2

[0035] The difference from Embodiment 1 is that this embodiment discloses a fixed base 6, an upper baffle 61, a protective sleeve 4, and a filter screen 42. The mounting mechanism includes a fixed base 6 and an upper baffle 61. One end of the upper baffle 61 has an insertion hole, and a threaded rod 62 is movably sleeved inside the insertion hole. The bottom of the threaded rod 62 is fixedly installed inside the fixed base 6, and the top of the threaded rod 62 is threadedly connected to a nut 63. Fixing blocks 65 are fixedly installed on both sides of the fixed base 6, and fixing bolts are threadedly connected to the surface of the fixing blocks 65. One end of the upper baffle 61 is fixedly installed with a... The pressure plate 64 has a friction pad 641 fixedly installed at its bottom. The friction pad 641 has an anti-slip groove 642 at its bottom. The protective mechanism includes a protective sleeve 4 and a filter screen 42. The inside of the protective sleeve 4 is movably sleeved on the bottom of the gas collection pipe 3. A protective side plate 41 is fixedly installed on the outside of the protective sleeve 4. The bottom of the inner cavity of the protective sleeve 4 is fixedly installed on the outside of the filter screen 42. A base 43 is fixedly installed inside the protective sleeve 4. An assembly frame 44 is detachably connected to the top of the base 43. A breathable membrane 45 is fixedly installed inside the assembly frame 44.

[0036] like Figure 2 , 4As shown in Figure 5, the operator first securely installs the fixing seat 6 onto the wall or bracket at the location to be tested using the fixing bolts on the surface of the fixing block 65. Then, the assembly plate 5 is placed between the fixing seat 6 and the upper baffle 61, aligning the insertion hole at one end of the upper baffle 61 with the threaded rod 62 inside the fixing seat 6 and inserting it. Next, the nut 63 at the top of the threaded rod 62 is rotated. As the nut 63 is tightened downwards, the upper baffle 61 gradually presses down, causing the friction pad 641 at the bottom of the pressing plate 64 to press firmly against the surface of the assembly plate 5. The anti-slip groove 642 at the bottom of the friction pad 641 increases the friction with the assembly plate 5, further improving the fixing effect. Through the combined action of the locking force of the threaded connection and the friction force, the gas detection body 1 is stably installed. When disassembly is required, the nut 63 is rotated in the opposite direction to loosen the upper baffle 61, allowing for convenient removal of the device for maintenance or relocation. After the device is put into use, the protective mechanism plays a crucial protective role at the bottom of the gas collection pipe 3. Before entering the gas collection pipe 3, the outside gas must first pass through the protective sleeve 4: the protective side plate 41 can prevent large foreign objects from contacting the protective sleeve 4 and avoid damage from collision; the gas first passes through the filter screen 42 to filter out dust, particles and other impurities in the air; then it passes through the breathable membrane 45 inside the assembly frame 44. The breathable membrane 45 can effectively prevent water vapor from entering while ensuring that the gas passes through smoothly. The base 43 provides stable support for the assembly frame 44, and the detachable assembly frame 44 makes it easy to replace the breathable membrane 45 later, avoiding impurities from affecting the accuracy and service life of the detection element.

[0037] Example 3

[0038] The difference from Embodiment 2 is that this embodiment discloses a clamping plate 661 and a slide rail 66. The slide rail 66 is fixedly installed inside the fixed base 6. The clamping plate 661 is slidably installed at both ends of the slide rail 66. A buffer post 662 is provided on the other side of the clamping plate 661. The other end of the buffer post 662 is fixedly installed on the inner wall of the fixed base 6.

[0039] like Figure 3 As shown, the assembly plate 5 is placed between the fixed base 6 and the upper baffle 61. At this time, the slide rail 66 inside the fixed base 6 plays its role. When the assembly plate 5 is inserted, it pushes the clamping plates 661 on both sides to slide along the slide rail 66 to both ends. The buffer column 662 is squeezed by the clamping plates 661 and undergoes elastic deformation. Under the rebound force of the buffer column 662, the clamping plates 661 on both sides will tightly clamp the two sides of the assembly plate 5, and perform preliminary lateral fixation of the assembly plate 5 to prevent it from shifting left and right during installation.

[0040] The working principle of this safety gas detection device will be explained in detail below.

[0041] like Figure 1-5As shown, the operator first securely installs the fixing seat 6 onto the wall or bracket at the location to be tested using the fixing bolts on the surface of the fixing block 65. Then, the assembly plate 5 is placed between the fixing seat 6 and the upper baffle 61, aligning the insertion hole at one end of the upper baffle 61 with the threaded rod 62 inside the fixing seat 6 and inserting it. Next, the nut 63 at the top of the threaded rod 62 is rotated. As the nut 63 is tightened downwards, the upper baffle 61 gradually presses down, causing the friction pad 641 at the bottom of the pressing plate 64 to press tightly against the surface of the assembly plate 5. Through the combined action of the locking force of the threaded connection and the friction force, the gas detection body 1 is securely installed. The gas collection pipe 3 collects the external gas after it has been processed by the protective mechanism and delivers it to the detection element inside the gas detection body 1. After the detection element detects the gas concentration, it transmits the detected signal to the processing module inside the gas detection body 1. The processing module analyzes and processes the signal, and the data is transmitted to the control panel 2 on the front. The display screen on the control panel 2 shows this information in real time for easy viewing by the operator. After the device is put into use, the protective mechanism at the bottom of the gas collection pipe 3 plays a crucial protective role. Before entering the gas collection pipe 3, the outside gas must first pass through the protective sleeve 4: the protective side plate 41 can prevent large foreign objects from contacting the protective sleeve 4 and avoid damage from collision; the gas first passes through the filter screen 42 to filter out dust, particles and other impurities in the air; then it passes through the breathable membrane 45 inside the assembly frame 44. The breathable membrane 45 can effectively prevent water vapor from entering, while ensuring that the gas passes through smoothly.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
