Description

Technical Field

[0001] The invention relates to the field of air purification, and in particular to air disinfection and purification equipment. Background Art

[0002] Air purification refers to providing overall solutions to various indoor environmental problems, such as sterilization and disinfection, dust reduction and haze removal, and removal of harmful decoration residues and odors. In people's daily lives, air purification and disinfection equipment is often used to purify the environment in which they live.

[0003] However, for some underground gas transportation projects, many gas transportation pipelines will be laid underground, and working wells will be set up at the intersection of the pipelines for regular maintenance and inspection of the transportation pipelines; because the working wells are in a closed state for a long time, the air inside is thin and there are certain harmful gases. Therefore, before the staff enter the working well, it is generally necessary to open the manhole cover and leave it open for a period of time, or use a fan to accelerate the air circulation inside the working well to purify the air inside the working well.

[0004] However, the above-mentioned method for purifying the air inside the working well has the following shortcomings:

[0005] (1) Opening the manhole cover directly and leaving it open for a period of time can allow the air inside the working well to diffuse outward, but the speed is relatively slow due to the natural circulation of air, and it takes a long time to wait, thus affecting the work progress;

[0006] (2) Although the use of a fan can speed up the air circulation inside the working well, if the working well is deep, the air at the lower end is still difficult to diffuse outward quickly, and the external air is difficult to effectively reach the lower end of the working well.

[0018] Compared with the related art, the air disinfection and purification equipment provided by the embodiment of the present invention has the following beneficial effects:

[0019] (1) By setting up a disinfection and purification mechanism, the disinfection and purification function of the air inside the working well can be realized. When in use, by setting the air intake pipe at the upper end of the working well and the exhaust pipe at the lower end of the working well, the air inside the working well can flow from bottom to top in sequence. On the one hand, it promotes the rapid flow of air and shortens the time for disinfection and purification of the air inside the working well, so that the staff can enter the working well in a short time to work; on the other hand, it can adapt to working wells of different depths well, ensure that the air at different positions can flow quickly, thoroughly absorb the air inside the working well and disinfect and purify it, so that the inside of the working well is in a safe environment, which is convenient for the staff to work;

[0020] (2) By setting up an air circulation part, the air inside the working well can be converted and circulated. It mainly uses the rotation of the winding rotating part to control the length of the exhaust pipe, so that it can adjust the length of the exhaust pipe according to the depth of the working well, ensuring that the purified gas discharged from the exhaust pipe flows from the bottom of the working well to the top, thereby accelerating the air flow speed inside the working well and making the purified air evenly diffuse inside the working well, realizing the function of thoroughly purifying the air inside the working well in a short time;

[0021] (3) By setting up a plugging part, when the air inside the working well is sucked out, the plugging bottom plate is tightly fitted with the wellhead of the working well, so that the wellhead of the working well can be sealed and separated from the external environment, so as to avoid the external air and the air inside the working well being mixed and sucked in, thereby realizing the function of sucking the air inside the working well separately, and speeding up the suction of the air inside the working well; in addition, by rotating the connecting piece to connect the plugging bottom plate to the shell, when the main plate is in a non-horizontal state, due to the effect of gravity, the plugging bottom plate can always be in a horizontal state, so that it can be in close contact with the wellhead of the working well, avoiding the appearance of gaps that affect its plugging effect, further increasing the stability and adaptability of the plugging bottom plate, and better meeting the use requirements of different environments.

[0022] (4) By setting up a moving mechanism, the air disinfection and purification equipment can be freely moved. Among them, the support part is set to be used in conjunction with the rotating handle to realize the automatic retraction function of the support rod. When the air disinfection and purification equipment is moved to the wellhead position of the working well, the height of the support rod can be adjusted accordingly according to the height of the wellhead of the working well, so that the support rod can provide stable support for the main body plate without hindering the air disinfection and purification equipment from passing through the wellhead of the working well, thereby increasing the flexibility of the support rod when used.

[0036] Please refer to Figure 3 , Figure 4 and Figure 6The air circulation part 22 includes a winding rotating part 221, an exhaust duct 222, a connecting duct 223, an air inlet duct 224 and a power assembly 225 for driving the winding rotating part 221 to rotate.

When the exhaust pipe 222 reaches the bottom end of the working well, it contacts the bottom end of the working well through the bottom of the isolation bucket to avoid the exhaust pipe 222 from contacting the bottom end of the working well and causing blockage, so that the purified air can smoothly flow into the inside of the working well through the exhaust hole; the power component 225 is arranged at the lower end of the inner wall of the shell 21, and the output end of the power component 225 is connected to the winding rotating part 221.

[0037] Please refer to Figure 3 and Figure 5 The sealing part 23 includes a sealing bottom plate 231, two rotating connecting members 232, two sliding rods 233 and two buffer springs 234.

[0038] Please refer to Figure 3 The disinfection and purification part 24 includes an air suction pump 241, an adsorption plate 242, a germicidal lamp 243, an ozone generator 244, a filter 245 and an external air intake pipe 246. The air suction pump 241, the adsorption plate 242, the germicidal lamp 243 and the ozone generator 244 are fixedly installed on the upper end of the inner wall of the shell 21 from top to bottom. The filter 245 is fixedly installed between the opposite sides of the inner wall of the shell 21 and is located directly below the air inlet at the upper end of the shell 21. The filter 245 is used to filter the air entering the shell 21 to remove the particles inside. The particulate matter is filtered out; the exhaust end of the external air intake pipe 246 is connected to the input end of the air suction pump 241, and the air outside the working well is sucked into the shell 21. The outside of the external air intake pipe 246 is connected to the upper end of the air intake pipe 224, so that the air suction pump 241 can simultaneously suck in the air outside the shell 21 and the air inside the working well, so that the two airs are mixed, thereby improving the air concentration inside the working well. The air intake end of the external air intake pipe 246 is located directly below the filter 245, and the output end of the ozone generator 244 is connected to the upper end of the exhaust connecting pipe 223.

[0039] Please refer to Figure 6 The power assembly 225 includes a driven gear 2251, a motor 2252 and a driving gear 2253. The driven gear 2251 is fixedly sleeved on the outer peripheral side of the winding rotating member 221. The motor 2252 is fixedly installed at the lower end of the inner wall of the shell 21. The driving gear 2253 is fixedly installed at the output end of the motor 2252, and the driving gear 2253 is meshed with the driven gear 2251. The two are adapted to be arranged. By rotating the motor 2252, the driven gear 2251 can drive the winding rotating member 221 to rotate synchronously, so that the winding rotating member 221 can complete the function of winding and lengthening the exhaust duct 222. The power assembly 225 is not limited to the above-mentioned structural form, and can also be other types.

[0040] Please refer to Figure 4 and Figure 7 The moving mechanism 3 includes a protective cover 31, a rotating handle 32, two supporting parts 33, a roller member 34 and a positioning rotating part 35. The protective cover 31 is fixedly mounted on the upper end surface of the main body plate 1, and the rotating handle 32 is rotatably mounted between the opposite sides of the inner wall of the protective cover 31, so that people can push the air disinfection and purification equipment conveniently. The two supporting parts 33 are symmetrically arranged on the upper end surface of the main body plate 1 with the rotating handle 32 as the symmetry center. The two supporting parts 33 are connected to the rotating handle 32. The roller member 34 is rotatably mounted on one end of the lower end surface of the main body plate 1 close to the rotating handle 32. The roller member 34 is composed of a roller and a rotating frame, and can rotate freely in the horizontal direction of the lower end of the main body plate 1.

[0041] Please refer to Figure 7 and Figure 8The support portion 33 includes a support rod 331, a movable part 332, a swing rod 333 and a gear 334. The upper end of the support rod 331 is rotatably connected to the end of the main plate 1 away from the rotating handle 32. When the air disinfection and purification equipment does not need to be moved, the support rod 331 is in contact with the ground, which can provide support for the main plate 1 so that it can remain stationary; the movable part 332 is horizontally slidably installed on the upper end surface of the main plate 1, and the end of the movable part 332 away from the support rod 331 extends to the inner side of the protective cover 31. The end of the main plate 1 close to the support rod 331 is symmetrically provided with two rotating The groove serves as a rotation space for the support rod 331 and the swing rod 333, so that the two can rotate normally on the main body plate 1. The swing rod 333 is rotatably installed on the inner side wall of the rotation groove. The two ends of the swing rod 333 are slidably connected with the support rod 331 and the movable member 332 respectively. A movable groove is provided on the outer peripheral side of the support rod 331 and the end of the movable member 332 close to the support rod 331, so that the swing rod 333 can swing normally following the movement of the movable member 332. A movable groove is provided on the movable member 332, so that when it pulls the swing rod 333 horizontally, the swing rod 333 can The gear 334 is fixedly mounted on one end of the rotating handle 32 close to the protective cover 31, and a rack is provided on one end of the movable part 332 close to the protective cover 31, and the gear 334 is meshed with the rack. By pressing the rotating handle 32 downward, the gear 334 can drive the movable part 332 to move horizontally, thereby realizing the rotation and contraction function of the support rod 331, so as to avoid the support rod 331 being too long and causing obstacles when the air disinfection and purification equipment is moved to the operating wellhead position; in addition, in order to prevent the entire air disinfection and purification equipment from being driven when the rotating handle 32 is turned downward, the main A pedal 4 is fixedly installed on the peripheral side of the body plate 1. When the rotating handle 32 is pressed downward to retract the support rod 331, the pedal 4 can be stepped on by the foot to keep the main body plate 1 away from the end of the rotating handle 32 in a stable state; if the rotating handle 32 is directly pressed downward to make the air disinfection and purification equipment rotate with the roller part 34 as the rotation center, not only the pressing force required is large, but if the rotation angle is too large, the air disinfection and purification equipment will fall over due to unstable center of gravity. If the above-mentioned moving mechanism 3 is used to retract the support rod 331, this problem will not occur.

[0042] The working principle of the air disinfection and purification equipment provided by the embodiment of the present invention is as follows:

[0043] Step 1: When in use, first open the manhole cover of the working well, and then move the air disinfection and purification device to the position just above the wellhead of the working well. When pushing, if the distance from the wellhead to the ground is lower than the distance from the support rod 331 to the ground, you can directly push the rotating handle 32 so that the blocking part 23 is just above the wellhead of the working well, and then release the rotating handle 32 so that the support rod 331 contacts the ground, thereby making the air disinfection and purification device in a stationary state;

[0044] If the distance from the wellhead to the ground is greater than the distance from the support rod 331 to the ground, the support rod 331 needs to be retracted first. When retracting, first step on the end of the pedal 4 close to the roller member 34 with your foot, and press the rotating handle 32 downward, so that the gear 334 can drive the movable member 332 to move horizontally, and the swing rod 333 can rotate synchronously with the movable member 332, so that the support rod 331 can be subjected to the thrust generated by the rotation of the swing rod 333, so that it begins to rotate toward the side close to the shell 21, until the bottom end of the support rod 331 rotates to a height higher than the wellhead, so that the air disinfection and purification equipment can be pushed to a position directly above the wellhead of the operating well, and then the rotating handle 32 is turned upward to make the support rod 331 rotate and reset, and contact the ground to provide support for the main plate 1, so that the air disinfection and purification equipment can remain in a stable state.

[0045] Step 2: Then, by contracting the two lifting members 25, the shell 21 and the sealing part 23 can be synchronously moved downward to approach the wellhead of the working well. When the lower end surface of the sealing bottom plate 231 contacts the wellhead of the working well, the shell 21 continues to move downward, so that the sealing bottom plate 231 compresses the buffer spring 234, thereby playing a certain buffering role on the sealing bottom plate 231 to avoid rigid contact between the two. After that, the lifting member 25 stops contracting, so that the sealing bottom plate 231 is tightly fitted with the wellhead of the working well.

[0046] Step three: Afterwards, the motor 2252 rotates forward, so that the driving gear 2253 drives the driven gear 2251 to rotate, and the winding rotating member 221 rotates synchronously with the driven gear 2251, so that the exhaust pipe 222 slowly extends into the working well until the exhaust pipe 222 moves to the bottom position of the working well, and the motor 2252 stops rotating. At this time, the air intake pipe 224 is at the upper end position of the working well, and the exhaust pipe 222 is at the lower end position of the working well.

[0047] Step 4: Then, the suction pump 241 is started to suck in the air inside the working well and the air outside the shell 21 respectively, and transport them to the inside of the shell 21. The mixed air first passes through the adsorption plate 242 to adsorb and filter out the particulate matter inside it, and then the bacteria are eliminated by the light irradiated by the sterilization lamp 243. Then the air enters the ozone generator 244, and the ozone inside it can further oxidize and sterilize the air. Finally, the treated air enters the exhaust pipe 222 through the connecting pipe 223, and then flows from the exhaust pipe 222 to the bottom of the working well. Since the bottom of the working well continuously has purified air entering, and the air at the upper end of the working well is continuously sucked out, the air inside the working well flows rapidly, and finally the internal air is quickly and thoroughly purified and disinfected.

[0048] Step 5: After the disinfection and purification is completed, the motor 2252 rotates in the reverse direction, which can cause the winding rotating member 221 to rotate in the reverse direction and wind up the exhaust pipe 222. Then, the air disinfection and purification equipment is moved away from the wellhead of the operating well, and the staff can go down the well to work.

[0049] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
