Abstract
Description
Technical Field
[0001] This invention relates to the field of cleaning equipment technology, and more particularly to vacuum cleaners. Background Technology
[0002] Activated carbon delayed bed for waste gas is used to treat the process flow of radioactive gaseous waste treatment systems (WGS) during power plant operation and shutdown. It delays the decay of radionuclides such as krypton and xenon by selectively adsorbing them with activated carbon in the guard bed and delayed bed, thereby reducing the radioactivity level of the waste gas and meeting emission requirements.
[0003] Because activated carbon will gradually become saturated and its adsorption capacity will decrease after a period of adsorption, the activated carbon inside the waste gas activated carbon delayed bed needs to be replaced after each cycle. In addition, after the activated carbon has adsorbed waste gas, it is easy to stick together and form large activated carbon blocks that cannot be removed from the outlet of the box.
[0004] Currently, there are no special tools for removing activated carbon from the activated carbon delay bed in the waste gas. The common method is for workers to use a hand scraper to reach into the chamber and break up the larger pieces of activated carbon before removing them. Since the chamber is usually fixed to the ground, it cannot be tilted, so the breaking and recycling process takes a long time. In addition, since the used activated carbon has a certain degree of radioactivity, prolonged contact with it can have a certain impact on the health of the workers.
[0005] Therefore, there is an urgent need for a vacuum cleaner to solve the above-mentioned technical problems. Summary of the Invention
[0006] The purpose of this invention is to provide a vacuum cleaner that can break up large, solid debris or debris connected to the environment by using the impact of the suction probe before it is absorbed, thus making the vacuum cleaner more versatile.

The circumferential end face of the abutment portion abuts against the inner circumferential wall of the exhaust chamber and can slide relative to it. An exhaust hole is provided on the circumferential side wall of the exhaust chamber. The impact member has an extended state and a retracted state. When it is in the extended state, the exhaust hole is located on the side of the abutment portion opposite to the impact portion.

The first elastic member enables the impact member to have a tendency to change from the extended state to the retracted state.
[0010] The vacuum cleaner body is used to generate airflow and control the direction of movement of the airflow;

[0017] As a preferred technical solution for the aforementioned vacuum cleaner, multiple brackets are provided, and the multiple brackets are spaced apart circumferentially along the probe body.
[0018] As a preferred technical solution for the aforementioned vacuum cleaner, the bracket further includes a second elastic element. Along the radial direction of the probe body, the second elastic element causes the end of the support leg connected to the universal ball to have a tendency to move away from the probe body.

[0037] like Figure 1-5As shown, the present invention provides a vacuum cleaner, including a vacuum probe 10, a vacuum body 20, and a connecting tube 30. The vacuum probe 10 includes a probe body 11, an impact member 12, and a first elastic member. The probe body 11 includes an exhaust chamber 111. The impact member 12 includes an impact portion 121 and an abutment portion 122. The impact portion 121 can extend out of the probe body 11 along the axial direction of the exhaust chamber 111. The circumferential end face of the abutment portion 122 abuts against and can slide relative to the inner circumferential wall of the exhaust chamber 111. An exhaust hole 112 is provided on the circumferential side wall of the exhaust chamber 111. The impact member 12 has an extended state and a retracted state. When in the extended state, the exhaust hole 112 is located on the abutment portion 122, facing away from the impact portion 121. On one side of 21, when in the contracted state, the exhaust port 112 is located between the abutment portion 122 and the impact portion 121. The first elastic member makes the impact member 12 have a tendency to change from the extended state to the contracted state. The vacuum body 20 is used to generate airflow and control the direction of airflow movement. The connecting pipe 30 includes an independent exhaust channel 31 and a vacuum channel 32. One end of the exhaust channel 31 and the vacuum channel 32 are both connected to the vacuum body 20. The other end of the exhaust channel 31 is equipped with a vacuum probe 10 and is located at the end away from the impact member 12. The other end of the vacuum channel 32 is provided with a first vacuum hole.
[0038] When the vacuum cleaner is idle, the impact member 12 is in a retracted state, with most of it located inside the exhaust chamber 111. The abutment portion 122 radially divides the exhaust chamber 111 into a first air chamber 1111 connected to the connecting pipe 30 and a second air chamber 1112 connected to the impact member 12. The first air chamber 1111 and the second air chamber 1112 are relatively closed. The exhaust port 112 is located between the abutment portion 122 and the impact portion 121, i.e., within the second air chamber 1112. When vacuuming is required, if the impurities are loose, the vacuum cleaner directly activates the vacuuming mode. The drive component inside the vacuum body 20 generates an airflow from the first suction port towards the vacuum body 20, and the airflow carries the impurities into the vacuum body 20. If impurities adhere to each other or to the environment, forming large and solid clumps that are difficult to pass through the first suction hole, or even if the suction force of the drive unit is insufficient to drive the clumps into the first suction hole, the vacuum cleaner first activates the impact mode. The suction probe 10 is then aligned with the clumps. The drive unit of the vacuum body 20 generates an airflow from the vacuum body 20 towards the suction probe 10. As the airflow enters the first air chamber 1111, the air pressure within the first air chamber 1111 rises rapidly and acts on the contact portion 122 of the impact member 12. The force of this force is denoted as Fair. This causes the impact member 12 to have a tendency to move away from the exhaust chamber 111 along the airflow direction. The first air chamber 1111 begins to compress the second air chamber 1112 and expands to its side. When F_air > F_elastic, F_elastic is the supporting force of the first elastic member on the abutment part 122. The first elastic member undergoes elastic deformation and begins to store energy. The impact member 12 switches from the compressed state to the extended state. Most of the impact member 12 extends axially out of the probe body 11, and the abutment part 122 compresses the second air chamber 1112 until the exhaust port 112 enters the second air chamber 1112 from the second air chamber 1112. A first air chamber 1111 is connected to the external environment of the exhaust chamber 111 via an exhaust port 112. The high-pressure gas in the first air chamber 1111 is discharged through the exhaust port 112, achieving rapid depressurization of the first air chamber 1111. The discharged high-pressure gas acts on the loosened impurities, exposing the unimpacted parts. At this time, the pressure (Fgas) suddenly decreases. When the elastic force (Felastic) is greater than the pressure (Fgas), the first elastic element returns to its original shape and moves against the contact part 122 toward the side where the first space is located. The impact member 12 changes from an extended state to a retracted state, thus venting the gas. The hole 112 falls back into the second air chamber 1112, and the first air chamber 1111 is closed again. The drive unit continues to supply gas into the exhaust chamber 111, causing the pressure in the first air chamber 1111 to rise again until F_gas is greater than F_ball. The impact member 12 switches from the retracted state to the extended state. This process is repeated. The impact part 121 of the impact member 12 can continuously strike the impurity block during the reciprocating movement, generating vibration and breaking the impurity block into loose impurities. Subsequently, the vacuum cleaner switches from the impact mode to the suction mode, and the impurities are absorbed by the first suction hole.
[0039] With this design, the vacuum cleaner not only has basic vacuuming functions, but also can break up and absorb large, solid debris or debris connected to the environment through the impact of the vacuum probe 10, making the vacuum cleaner more versatile.
[0040] Optionally, the end of the impact portion 121 of the impact member 12 opposite to the abutment portion 122 is tapered.
[0041] Optionally, the vacuum cleaner body 20 also includes a housing and a collection box 21, the collection box 21 being used to collect impurities, and the collection box 21 being slidably connected to the housing for easy emptying.
[0042] Optionally, the probe body 11 also includes a suction chamber 113, which is independent of the exhaust chamber 111. A second suction hole 114 is provided on the side wall of the suction chamber 113, and the suction channel 32 communicates with the suction chamber 113 through the first suction hole. With this design, the inlet of the suction channel 32 and the outlet of the exhaust channel 31 are integrated into the probe body 11, allowing for easy operation by simply controlling the orientation of the probe body 11.
[0043] Optionally, the probe body 11 includes a first housing and a second housing. The second housing is fitted outside the first housing. An exhaust chamber 111 is formed inside the first housing, and a dust suction chamber 113 is formed between the second housing and the first housing. An exhaust port 112 is opened in the first housing, and a second dust suction port 114 is opened in the second housing. Specifically, the first housing can be divided into an exhaust area and a connecting area. The connecting area is fitted inside the housing and fixed to the second housing. The exhaust area has an exhaust port 112, and the first dust suction port is opened axially on the end face of the second housing facing the impact member 12. This allows the impact member 12 to be located in the center of the probe body 11. During impact operation, the force is applied as axially as possible to avoid the dust suction probe 10 from violently swinging radially. The exhaust port 112 can spray high-pressure gas radially to disperse impurities. The first dust suction port is arranged circumferentially along the impact member 12 and faces downward, enabling more comprehensive absorption of impurities.
[0044] Optionally, the first housing and the second housing are integrally formed.
[0045] Optionally, the connecting pipe 30 includes a first pipe body 33 and a second pipe body 34. The second pipe body 34 is fitted outside the first pipe body 33. An exhaust channel 31 is formed inside the first pipe body 33, and a suction channel 32 is formed between the second pipe body 34 and the first pipe body 33. The first pipe body 33 is connected to the first housing, and the second pipe body 34 is connected to the second housing. This arrangement allows the connecting pipe 30 to form both an exhaust channel 31 and a suction channel 32. From the outside, only one connecting pipe 30 is visible, facilitating storage and reducing the number of connection holes on the suction probe 10 and the suction body 20, thus ensuring the airtightness of both parts. Furthermore, if any pipe becomes blocked or damaged, the corresponding pipe body can be replaced, reducing maintenance costs and avoiding material waste.
[0046] Optionally, the connecting pipe 30 is provided with a connecting joint 35 for fixing to the vacuum body 20.
[0047] Specifically, the connecting connector 35 includes a threaded fixing part and a connecting part. One end of the threaded fixing part can be slidably connected to the connecting part, and the other end is connected to the threaded connecting part provided on the vacuum body 20. The other end of the connecting tube 30 may also be provided with a connecting connector 35 to fix it to the vacuum probe 10.
[0048] When the vacuum cleaner cleans the waste gas activated carbon delayed bed, the delayed bed consists of a large number of cylindrical boxes, and a large amount of used activated carbon is piled up inside the boxes. The activated carbon is clumped together and needs to be inserted into the box. When the impact mode is activated to break up the activated carbon, the impact probe is prone to radial swinging due to the lack of support and fixation from the operator, and may hit the side wall of the box. If the impact component 12 impacts the side wall of the box, it is very easy to damage the side wall.
[0049] Therefore, optionally, the vacuum probe 10 provided by the present invention further includes a bracket 13. The bracket 13 includes a plurality of legs 131 spaced apart circumferentially along the probe body 11. One end of each leg 131 is connected to the probe body 11, and the other end is connected to a universal ball 132. In this way, by the legs 131 pressing against the side wall of the housing, the impact member 12 is straightened and maintained at the center line position of the housing. As the vacuum probe 10 extends, the universal ball 132 can provide rolling friction, reducing the friction between the legs 131 and the side wall of the housing, and facilitating direction adjustment.
[0050] Optionally, multiple supports 13 are provided, with the multiple supports 13 spaced apart circumferentially along the probe body 11. In this way, the vacuum probe 10 has multiple support points along the axial direction, making it more stable under impact.
[0051] Optionally, the bracket 13 also includes a second elastic element. Along the radial direction of the probe body 11, the second elastic element causes the end of the support leg 131 connected to the universal ball 132 to tend to move away from the probe body 11. This arrangement allows the support leg 131 to be retracted before the vacuum probe 10 is placed into the housing, so that the end of the support leg 131 connected to the universal ball 132 is close to the vacuum probe 10. At this time, the second elastic element undergoes elastic deformation and begins to store energy. After the vacuum probe 10 is placed into the housing, the support leg 131 loses the external force, the second elastic element recovers its deformation, and drives the support leg 131 to unfold, so that the end of the support leg 131 connected to the universal ball 132 moves away from the probe body 11 until it abuts against the side wall of the housing.
[0052] Optionally, the support leg 131 is rotatably connected to the probe body 11. Specifically, the bracket 13 also includes a support rod 133, one end of which is rotatably connected to the probe body 11 or the support leg 131, and the other end is slidably connected to another component. When the second elastic element is a torsion spring, it is sleeved on the rotating shaft; if the second elastic element is a compression spring, it acts on the sliding end of the support rod 133.
[0053] In other embodiments, the support leg 131 is extendable and retractable along the probe body 11.
[0054] Optionally, the support leg 131 is positioned along the axial direction of the probe body 11, with one end connected to the universal ball 132 close to the side where the impact member 12 is located, and the rotation angle of the support leg 131 relative to the probe body 11 is less than 90°. This arrangement allows the support leg 131 to be abutted against by the top surface of the housing at the outlet position when the vacuum probe 10 is removed from the housing, enabling it to swing towards the side where the probe body 11 is located, changing from an extended state to a retracted state, thereby altering the radial volume of the vacuum probe 10 and allowing it to smoothly exit from the housing.
[0055] Furthermore, the connecting pipe 30 is also provided with a limiting component, which includes a limiting frame, a clamping member, and an abutment member. The limiting frame includes a limiting rod, the extension direction of which is parallel to the radial direction of the connecting pipe 30. The limiting frame can slide along the extension direction of the connecting pipe 30. The clamping member is slidably connected to the limiting rod and can be fixed to the end face at the top opening of the housing. The abutment member can slide along the extension direction of the connecting pipe 30 and is located between the limiting frame and the vacuum cleaner body 20. When cleaning the chamber of the waste gas activated carbon delayed bed, after placing the dust suction probe 10 into the chamber, first fix the limiting frame to the entrance end of the chamber with the clamping member. Then, adjust the distance between the abutment member and the impact part 121 of the impact member 12 according to the depth of the chamber. Then lock the abutment member and the connecting pipe 30 at this position. As the dust suction probe 10 continues to go deeper, when the abutment member abuts against the limiting frame, the dust suction probe 10 will not be able to continue to extend along the axial direction to the bottom of the chamber, so as to prevent the impact member 12 from damaging the bottom of the chamber.
[0056] Furthermore, a limit switch is installed on the limit frame. When the abutting part comes into contact with the limit frame and triggers the limit switch, the vacuum body 20 can automatically switch from the self-impact mode to the vacuum mode. This means that when performing cleaning operations, the staff no longer need to stay in the chamber of the activated carbon delay bed, reducing the time of contact with radioactive materials and realizing the automation of the cleaning operation.
[0057] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
