Description

Technical Field

[0001] This utility model relates to the technical field of chemical gas detection devices, specifically a safe and environmentally friendly device for detecting leaks of chemical process gases. Background Technology

[0002] Chemical processes, also known as chemical technology or chemical production technology, generally refer to the methods and processes by which raw materials are transformed into products through chemical reactions, including all measures to achieve this transformation. During the chemical reactions produced in chemical processes, various gases are generated. Some of these gases can cause environmental pollution or harm human health if they leak. Therefore, safety and environmental protection devices are usually used during the chemical process to detect the leakage of chemical process gases in a timely manner.

[0003] Existing safety and environmental protection devices for chemical process gas leaks are typically designed with detachable installation components and detection instruments. However, the detector is usually inserted vertically into or removed from the installation component. This makes it difficult for users to hold the top of the detector when removing it from the installation component; they can only press the front of the detector upwards or downwards, making the disassembly and assembly of the detector and installation component cumbersome and time-consuming. In addition, since the detector is usually secured by a fixed outer frame during installation, frequent friction between the detector and the frame can cause wear and even gaps between the detector and the frame of the installation component over time. This makes it difficult for the detector to be stably secured in the installation component later, affecting the normal operation of the detector on the installation component. Summary of the Invention

[0004] The purpose of this invention is to provide a safe and environmentally friendly device for detecting leaks of chemical process gas, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety and environmental protection device for detecting leaks in chemical process gases, comprising a back plate, mounting holes at the four corners of the front of the back plate, a vertical plate fixedly connected to the center of the front of the back plate, a support plate fixedly connected to the bottom of the vertical plate, a columnar hinge installed on one side of the top of the support plate, a retaining frame movably connected to the top of the columnar hinge, a detector movably connected to the inner side of the retaining frame, fastening screws on both sides of the retaining frame, a groove on the top of the front of the vertical plate, a traction rope inside the groove, a mounting plate movably connected to the center of the back plate, a spring on the back of the mounting plate, and a retaining groove in the center of the vertical plate.

[0006] Preferably, a first fixing block is fixedly connected to the top of one side wall of the vertical plate, and a second fixing block is fixedly connected to the top of both side walls of the card frame.

[0007] Preferably, the fastening screw is threadedly connected to the second fixing block, and the fastening screw is movably connected to the frame through the second fixing block.

[0008] Preferably, the fastening screw is movably threadedly connected to the first fixing block, and the clip frame is movably connected to the vertical plate through the fastening screw and the first fixing block.

[0009] Preferably, one end of the traction rope is fixedly connected to the card frame, and the other end of the traction rope is fixedly connected to the inner wall of the groove.

[0010] Preferably, one end of the spring is fixedly connected to the back plate, and the other end of the spring is fixedly connected to the plate.

[0011] Preferably, two adhesive pads are fixedly connected to the front side of the plate, and the adhesive pads are movably connected to the detector through the plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This safety and environmental protection device for detecting leaks in chemical process gases uses a clamping frame, cylindrical hinges, grooves, and traction ropes to allow the mounting components on the device to be tilted. This allows the detector to be inserted into or pulled out of the mounting components by pinching the top of the detector, making installation and disassembly more convenient, thereby reducing the difficulty of assembling and disassembling the detector and saving time.

[0014] This safe and environmentally friendly device for detecting leaks in chemical process gases uses springs, mounting plates, and fastening screws to fill the gaps caused by friction between the mounting components and the detector. This ensures that the detector remains firmly locked inside the mounting components, increasing the stability of the detector after docking with the components and reducing any adverse effects on its normal operation.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components.

[0023] like Figures 1 to 4 As shown, the safety and environmental protection device for detecting chemical process gas leaks in this embodiment includes a back plate 1. Mounting holes 2 are provided at the four corners of the front of the back plate 1. A vertical plate 4 is fixedly connected to the center of the front of the back plate 1. A support plate 16 is fixedly connected to the bottom of the vertical plate 4. A columnar hinge 9 is installed on one side of the top of the support plate 16. A retaining frame 8 is movably connected to the top of the columnar hinge 9. A detector 3 is movably connected to the inner side of the retaining frame 8. Fastening screws 6 are provided on both sides of the retaining frame 8. A groove 11 is provided at the top of the front of the vertical plate 4. A traction rope 10 is provided inside the groove 11. A mounting plate 12 is movably connected to the center of the back plate 1. A spring 13 is provided on the back of the mounting plate 12. A retaining groove 14 is provided in the center of the vertical plate 4.

[0024] Specifically, the back plate 1 is fixed to the wall via mounting holes 2 and expansion screws that match the mounting holes 2, allowing the mounting components of this device to be fixed first, facilitating the subsequent snapping and fixing of the detector 3 onto the back plate 1. The vertical plate 4 and the support plate 16 form a frame structure fixed to the back plate 1, allowing the detector 3 to be supported on the front of the back plate 1 after being placed in the frame 8, thus enabling the detector 3 to be placed more stably on the back plate 1. The top of the frame 8 is flush with the top of the vertical plate 4, and the front of the frame 8 extends inward, allowing the frame 8 to support the front of the detector 3, thereby helping the detector 3 to remain stable on the back plate 1. The fastening screw 6 is used to temporarily secure the frame 8 and the vertical plate 4. The fastening mechanism allows the detector 3 to be firmly attached to the front of the back plate 1 after it is fully aligned with the frame 8 and the back plate 1, thus temporarily fixing the detector 3. The groove 11 is used to store the traction rope 10 in a slack state. The traction rope 10 is used to limit the frame 8 after it is rotated to a set angle, preventing the frame 8 from rotating excessively and making it difficult to disassemble and assemble the detector 3. The plate 12, together with the spring 13, allows the detector 3 to be clamped between the frame 8 and the back plate 1. This ensures that the detector 3 can still be stably clamped on the mounting assembly composed of the back plate 1 and the frame 8 after frequent disassembly and assembly, thereby maintaining the stability of the detector 3 on the mounting assembly and reducing the adverse effects on the normal operation of the detector 3.

[0025] Furthermore, a first fixing block 5 is fixedly connected to the top of one side wall of the vertical plate 4, and a second fixing block 7 is fixedly connected to the top of both sides of the frame 8. The first fixing block 5 and the second fixing block 7 enable the fastening screw 6 to connect with the vertical plate 4 and the frame 8, thereby fixing the frame 8 to the vertical plate 4.

[0026] Furthermore, the fastening screw 6 is connected to the second fixing block 7 by a movable thread. The fastening screw 6 is movably connected to the frame 8 through the second fixing block 7. After the fastening screw 6 is loosened, it will separate from the first fixing block 5, but will still be threaded into the second fixing block 7, so that the frame 8 can be temporarily separated from the vertical plate 4, thereby reducing the interference to the rotation of the frame 8.

[0027] Furthermore, the fastening screw 6 is movably threadedly connected to the first fixing block 5, and the clamping frame 8 is movably connected to the vertical plate 4 through the fastening screw 6 and the first fixing block 5. After the clamping frame 8 is engaged with the screw holes on the fastening screw 6 and the first fixing block 5, it will be tightly attached to the vertical plate 4, thereby achieving temporary locking between the clamping frame 8 and the vertical plate 4, so that the detector 3 can be fixed on the device.

[0028] Furthermore, one end of the traction rope 10 is fixedly connected to the frame 8, and the other end of the traction rope 10 is fixedly connected to the inner wall of the groove 11. The traction rope 10 is a steel wire rope, which is not easily deformed, so that the frame 8 can remain in a limited state after rotating along the column hinge 9 to the tilt angle, thereby facilitating the pinching of the top of the detector 3 and its oblique placement into the interior of the frame 8.

[0029] Furthermore, one end of the spring 13 is fixedly connected to the back plate 1, and the other end of the spring 13 is fixedly connected to the plate 12. After deformation, the spring 13 can generate a force that pushes against the plate 12, so that the plate 12 can stick tightly to the back of the detector 3, and the detector 3 can be more firmly locked between the frame 8 and the back plate 1, thereby facilitating the stable assembly and docking of the detector 3 with the back plate 1.

[0030] Furthermore, two rubber pads 15 are fixedly connected to the front of the plate 12. The rubber pads 15 are movably connected to the detector 3 through the plate 12. The rubber pads 15 can increase the friction on the front of the plate 12, making the plate 12 less likely to slip along the back of the detector 3, thereby increasing the stability of the detector 3 placed in the card frame 8.

[0031] The usage method of this embodiment is as follows: When using this safety and environmental protection device for detecting chemical process gas leaks, the back plate 1 of this device needs to be fixed to the location where gas will be generated during chemical process production through the mounting hole 2. Then, the fastening screw 6 can be loosened so that the fastening screw 6 separates from the first fixing block 5, but still remains on the second fixing block 7. At this time, the clamping frame 8 is unlocked from the vertical plate 4. Then, the clamping frame 8 can be tilted forward along the columnar hinge 9 until the traction rope 10 connected to the clamping frame 8 is taut. The clamping frame 8 will be in a tilted state. At this time, a large opening appears between the top of the vertical plate 4 and the clamping frame 8. Then, pinch... Place the detector 3 diagonally inside the frame 8, then rotate the frame 8 back to its initial position and tighten the fastening screw 6 so that the fastening screw 6 re-engages with the first fixing block 5. At this time, the frame 8 will be pressed against the vertical plate 4, and the detector 3 will be pushed towards the center of the front of the back plate 1. The plate 12 in the center of the back plate 1 will be compressed by the detector 3, which will compress the spring 13. The spring 13 will generate a reverse force, pushing the plate 12 towards the back of the detector 3, so that the plate 12 is pressed against the detector 3. This will clamp the detector 3 between the frame 8 and the back plate 1 and keep it stationary.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
