Description

Technical Field

[0001] This utility model relates to the field of gas ionization chamber technology, and in particular to a detachable and maintainable gas ionization chamber. Background Technology

[0002] A gas ionization chamber is a device that uses the phenomenon of gas ionization to detect and measure radiation (such as X-rays, gamma rays, charged particles, etc.). Its core principle is to ionize the gas through radiation to generate charges, and then collect and measure these charges to achieve the detection and analysis of radiation.

[0003] A search revealed an ionization chamber device for a photoionization sensor, publication number CN220934010U. This device includes a housing with an air inlet on one side. A sensing component is installed within the housing's inner cavity. A connecting chamber is fixed to the upper surface of the housing, and an ultraviolet (UV) module is mounted on the upper surface of the connecting chamber. The sensing component includes four feet fixed to the bottom of the housing's inner cavity. An element plate is movably connected to the upper surface of each foot. Hand-tightened bolts, threaded with the feet, are fitted around the element plate. A negative electrode plate is mounted on one side of the upper surface of the element plate, and a capture plate is mounted on its surface. A positive electrode plate is mounted on the other side of the upper surface of the element plate. In this invention, rotating the hand-tightened bolts facilitates the assembly of the element plate and the housing, making the sensing components within the housing easy to inspect and maintain. Simultaneously, by squeezing the locking block, the cover plate can be disassembled, allowing the UV module and ionization chamber to be separated. After the UV module's service life ends, new parts can be replaced.

[0004] Based on the aforementioned patent, by disassembling and assembling the cover plate, the ultraviolet module and the ionization chamber can be separated. After the ultraviolet module's service life ends, new parts can be replaced. However, after the cover plate and the outer shell are separated, the sealing of the connection part is poor. In order to address this technical problem, this application proposes a detachable and maintainable gas ionization chamber. Utility Model Content

[0005] The purpose of this invention is to address the poor sealing performance of the connection between the cover plate and the outer shell when they are separable. A detachable and maintainable gas ionization chamber is proposed, which allows the cover plate to be removed from the ionization chamber body by pressing the pull handle. This eliminates the need for tools, facilitating cleaning of the internal electrode plates, significantly improving maintenance efficiency. Furthermore, the annular support plate presses down on the sealing ring, dynamically tightening it for a more secure seal.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable and maintainable gas ionization chamber, comprising an ionization chamber body, a cover plate at the top of the ionization chamber body, fixing plates fixedly connected to both the front and rear sides of the cover plate, two fixing blocks fixedly connected to both the front and rear sides of the ionization chamber body, a pull handle at the opposite end of each fixing plate on both the front and rear sides, the pull handle being connected to the fixing block via a fixing component, a knob at the top of the cover plate, a screw fixedly connected to the inner wall of the knob, the outer wall of the screw being rotatably connected to the inner wall of the cover plate, a threaded sleeve threadedly connected to the outer wall of the screw, and a sealing component provided on the outer wall of the threaded sleeve.

[0007] Furthermore, the fixing component includes a movable rod fixedly connected to one end of the front and rear pull handles, the outer wall of the movable rod being slidably connected to the inner wall of the fixing plate, and connecting rods being rotatably connected to both sides of the outer wall of the movable rod. A locking block is fixedly connected to the other end of each connecting rod, and the outer wall of the locking block is slidably connected to the inner wall of the fixing plate.

[0008] Furthermore, each of the left and right fixing blocks has a slot at one end opposite to the other, and the shape of the fixing block matches the shape of the slot.

[0009] Furthermore, a spring is sleeved on the outer wall of the moving rod, one end of the spring is connected to the pull handle, and the other end of the spring is connected to the fixed plate.

[0010] Furthermore, the sealing assembly includes an L-shaped connecting rod fixedly connected to both sides of the outer wall of the threaded sleeve, and an annular support plate fixedly connected to the bottom end of the L-shaped connecting rod. The outer wall of the annular support plate is slidably connected to the inner wall of the cover plate.

[0011] Furthermore, a sealing ring is fixedly connected to the bottom end of the annular support plate, and a sealing groove is provided at the top end of the ionization chamber body, with the sealing ring matching the shape of the sealing groove.

[0012] Furthermore, the outer wall of the threaded sleeve is fixedly connected to a slider, and the outer wall of the slider is slidably connected to the inner wall of the cover plate.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the pull handles on the fixing plates on both sides of the button move the moving rod into the fixing block, thereby driving the locking block to retract into the fixing plate through the connecting rod, eliminating the locking between the locking block and the locking slot. The cover plate can be removed without tools, which facilitates the cleaning of the internal electrode plate and greatly improves maintenance efficiency.

[0014] 2. In this utility model, the cover plate is placed on the main body of the ionization chamber, allowing the sealing ring to enter the sealing groove. Then, the knob is rotated, causing the threaded sleeve to move down, thereby pressing the sealing ring down with the annular support plate, making it dynamically tighter and achieving a tighter seal.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3This utility model provides an embodiment of a detachable and maintainable gas ionization chamber, comprising an ionization chamber body 1, a cover plate 2 at the top of the ionization chamber body 1, a fixing plate 3 fixedly connected to both the front and rear sides of the cover plate 2, two fixing blocks 4 fixedly connected to both the front and rear sides of the ionization chamber body 1, a pull handle 5 at one opposite end of the fixing plate 3 on both the front and rear sides, a moving rod 6 fixedly connected to one opposite end of the pull handle 5 on both the front and rear sides, the outer wall of the moving rod 6 slidably connected to the inner wall of the fixing plate 3, a connecting rod 8 rotatably connected to both sides of the outer wall of the moving rod 6, a locking block 9 fixedly connected to the other end of the connecting rod 8, the outer wall of the locking block 9 slidably connected to the inner wall of the fixing plate 3, a locking groove 10 opened at one opposite end of the fixing block 4 on both the left and right sides, the locking block 9 and the locking groove 10 being shaped to fit together, a spring 7 sleeved on the outer wall of the moving rod 6, one end of the spring 7 connected to the pull handle 5, and the other end of the spring 7 connected to the fixing plate 3.

[0019] Specifically, when the cover plate 2 is pressed onto the ionization chamber body 1, the fixing plate 3 on the cover plate 2 will enter between the two fixing blocks 4, and the locking block 9 on the fixing plate 3 will be squeezed into the fixing plate 3 by the fixing blocks 4. The locking block 9 will then drive the moving rod 6 to move through the connecting rod 8. The moving rod 6 will then compress the spring 7 through the pull handle 5. When the cover plate 2 moves the fixing plate 3 to the horizontal position of the locking groove 10 on the fixing block 4, the spring 7 will rebound the pull handle 5, causing the pull handle 5 to push the locking block 9 outward through the moving rod 6 and the connecting rod 8, so that the locking block 9 enters the locking groove 10, thereby fixing the cover plate 2 onto the ionization chamber body 1.

[0020] Reference Figure 2 and Figure 4 A knob 11 is provided at the top of the cover plate 2. A screw 12 is fixedly connected to the inner wall of the knob 11. The outer wall of the screw 12 is rotatably connected to the inner wall of the cover plate 2. A threaded sleeve 13 is threadedly connected to the outer wall of the screw 12. L-shaped connecting rods 15 are fixedly connected to both sides of the outer wall of the threaded sleeve 13. An annular support plate 16 is fixedly connected to the bottom end of the L-shaped connecting rod 15. The outer wall of the annular support plate 16 is slidably connected to the inner wall of the cover plate 2. A sealing ring 17 is fixedly connected to the bottom end of the annular support plate 16. A sealing groove 18 is opened at the top of the ionization chamber body 1. The sealing ring 17 and the sealing groove 18 are matched in shape. A slider 14 is fixedly connected to the threaded sleeve 13. The outer wall of the slider 14 is slidably connected to the inner wall of the cover plate 2.

[0021] Specifically, the sliders 14 on both sides of the outer wall of the threaded sleeve 13 slide on the inner wall of the cover plate 2, thereby limiting the threaded sleeve 13 so that the threaded sleeve 13 can maintain linear movement. The sealing ring 17 fits into the sealing groove 18. When the annular support plate 16 squeezes the sealing ring 17 into the sealing groove 18, the sealing ring 17 will be flattened, making the sealing ring 17 and the sealing groove 18 contact more tightly.

[0022] Working principle: When it is necessary to clean the electrode plates inside the ionization chamber body 1, the pull handles 5 on both sides of the fixed plate 3 can be pressed to move the moving rod 6 into the fixed plate 3. The moving rod 6 then moves the connecting rods 8 on both sides, causing the connecting rods 8 to pull the locking blocks 9 on both sides into the fixed plate 3. This causes the locking blocks 9 to disengage from the locking slots 10 on the fixed blocks 4 on both sides, thereby removing the restriction on the fixed plate 3. This allows the cover plate 2 to be opened, and the electrode plates inside can then be cleaned. After the cover plate 2 is connected to the ionization chamber body 1, the knob 11 is turned to rotate the screw 12. The screw 12 then moves the threaded sleeve 13 downward, causing the L-shaped connecting rod 15 to move downward. The L-shaped connecting rod 15 then moves the annular support plate 16 downward. The annular support plate 16 presses down the sealing ring 17, pressing it tightly into the sealing groove 18, so that the sealing ring 17 and the sealing groove 18 fit tightly together.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
