Description

Technical Field

[0001] This invention relates to the field of decontamination equipment technology, specifically to a decontamination device and method for post-disaster chemical decontamination sites. Background Technology

[0002] After a chemical disaster, chemicals may contaminate the surrounding environment, equipment, and buildings. If these chemical pollutants are not treated promptly, they will continue to harm human health and ecosystems. Decontamination work aims to remove or reduce the degree of contamination from these harmful chemicals, restoring the affected area to a relatively safe state.

[0003] The existing decontamination method involves first cleaning residue from the walls with a sponge, then rinsing the walls with clean water, and finally rinsing the floor. However, during the decontamination process, existing equipment encounters problems. Due to varying corner angles, when the angle is greater than 90°, the equipment may deviate from the wall. Conversely, when the angle is less than 90°, the equipment may struggle to reach the corner, rendering the corners unwashable and requiring manual cleaning, which is inefficient. Furthermore, the sponge remains pressed against the wall for extended periods, hindering water flow and resulting in ineffective corner cleaning. This necessitates multiple cleaning sessions, further compromising efficiency and cost control. Summary of the Invention

[0004] To avoid the shortcomings of the prior art, the present invention provides a post-disaster chemical site decontamination device and decontamination method.

[0005] The present invention adopts the following technical solution to solve the technical problem: a decontamination device for post-disaster chemical sites, comprising a movable frame, a spray frame, and a decontamination mechanism;

The transmission assembly is connected to the output end of the waterproof motor and the transmission shaft. The sliding frame is mounted on the transmission shaft. The support spring is installed between the transmission shaft and the sliding frame. The cleaning sponge is installed on the outside of the sliding frame.

[0008] Furthermore, the number of drive shafts, sliding frames, support springs, and cleaning sponges in the decontamination mechanism shall not be less than two.

[0009] Furthermore, it also includes a swing plate mechanism, which includes a swing plate, a slide rod, a bent rod, a locking structure, and a return spring; the swing plate is mounted on the movable frame, the slide rod and the bent rod are fixedly connected, one end of the slide rod and the bent rod are mounted on the swing plate, and the other end is mounted on the movable frame, the bent rod has a waist-shaped groove, and the return spring is mounted on the movable frame, with one end of it fixedly connected to the slide rod.

[0010] Furthermore, the locking structure of the swing plate mechanism includes a locking nut, which is installed and connected to the movable frame through the waist-shaped groove opened on the bent rod.

[0011] Furthermore, it also includes a corner cleaning mechanism, which includes a corner cleaning frame, a flow guide, a sealing block, and a fixed threaded bracket; the corner cleaning frame is installed on the swing plate, the flow guide is fixedly connected to the corner cleaning frame and communicates with it, the sealing block is slidably connected to the flow guide, the sealing block has internal threads, one end of the fixed threaded bracket is threadedly connected to the sealing block, and the other end is fixedly connected to the spray frame.

[0012] Furthermore, the sealing block has a through hole, and its lower end is connected to a water source.

[0013] Furthermore, it also includes a baffle mechanism, which includes a sealing plate, a guide block, and a connecting spring; the sealing plate is slidably connected to the guide block, the guide block is mounted on the spray frame, and the upper end of the connecting spring is connected to the sealing plate, while the lower end is connected to the sealing block.

[0014] Furthermore, it also includes a guiding mechanism, which comprises a swing rod, a fixed block, a limiting block, a rotating rod, a contact rod, a pressing rod, a rotating disk, a guide block, and a protrusion. There are two swing rods and two fixed blocks. The fixed blocks are respectively fixed to the sides of the moving frame and the swing plate. One end of each swing rod is connected to one of the two fixed blocks, and the other end is connected to the limiting block. The rotating rod is mounted on the drive shaft and slidably connected to the limiting block. The contact rod is slidably connected to the rotating rod. One end of the pressing rod is connected to the upper end of the contact rod, and the other end is connected to the sealing plate. The rotating disk is mounted above the sliding frame and has a guide block and a protrusion.

[0015] Furthermore, it also includes rollers, each of which is mounted in an array on the front side of the movable frame and located between the decontamination mechanisms.

[0016] A decontamination method for post-disaster chemical sites, using the post-disaster chemical site decontamination device as described in claims, includes the following steps:

[0017] Step 1: The staff starts the waterproof motor. The waterproof motor rotates, which drives the transmission component installed at the output end to rotate. The transmission shaft connected to the transmission component also rotates. The sliding frame installed on the transmission shaft drives the cleaning sponge on the outside to rotate. At this time, the cleaning sponge cleans the wall in front. When the sliding frame rotates to a certain angle, it can squeeze the cleaning sponge together with the wall in front of the cleaning sponge, squeezing out the water inside the cleaning sponge. The cleaning sponge continues to rotate, and then the staff cleans the entire wall.

[0018] Step 2: The staff moves the moving frame to the corner of the wall. At this time, the swing plate is squeezed and the slide rod installed on the swing plate slides backward. At the same time, the return spring behind the slide rod is compressed until the swing plate is close to the wall. Then, the staff rotates the locking nut to lock the bent rod. The slide rod fixed to the bent rod is locked at the same time, so that the swing plate cannot move.

[0019] Step 3: During the rotation of the swing plate, the corner cleaning rack installed above the swing plate rotates, which drives the flow guide to rotate. At this time, the sealing block moves downward along the fixed threaded frame, and the through hole on the sealing block is exposed. Water is injected into the flow guide through the through hole on the sealing block, and then flows into the corner cleaning rack through the flow guide. Finally, it is sprayed from the corner cleaning rack to the corner of the wall.

[0020] Step 4: As the sealing block moves downward, it drives the connecting spring above to move downward. The connecting spring drives the sealing plate above to move downward along the guide block, blocking part of the spray nozzles on the upper part of the spray rack, leaving only the spray nozzles for cleaning the corners. Water sprays from the left-out spray nozzles to the corners of the wall.

[0021] Step 5: The sealing plate descends, causing the pressure rod to descend. The pressure rod then causes the contact rod to descend, with the lower end of the contact rod abutting against the guide block. The drive shaft rotates, causing the sliding frame to rotate. The rotating disk mounted on the sliding frame rotates. As the rotating disk rotates, the contact rod moves along the guide block and protrusion to the outside of the rotating disk, bringing the rotating disk closer to the corner of the wall. The cleaning sponge under the rotating disk can then adhere more closely to the corner, increasing the cleaning effect until the cleaning is complete.

[0022] This invention provides a decontamination device and method for post-disaster chemical sites, which has the following beneficial effects:

[0023] 1. The cleaning and disinfection mechanism of the present invention can automatically rotate to clean the wall surface and automatically squeeze out excess water from the cleaning sponge, eliminating the need for staff to manually squeeze out excess water from the sponge, which helps ensure work efficiency.

[0024] 2. The present invention is equipped with a swing plate mechanism, which ensures that the decontamination device will not detach from the wall when it is near a corner, and can be applied to corners at various angles, which is conducive to ensuring work efficiency.

[0025] 3. The present invention is equipped with a corner cleaning and disinfection mechanism and a baffle mechanism, which can spray water from both sides to the corner when cleaning the corner, making the corner cleaning more thorough and improving work efficiency.

[0026] 4. The guiding mechanism of this invention allows the cleaning sponge to get closer to the corner when the cleaning device is cleaning the corner, improving the cleaning effect of the cleaning sponge on the corner and helping to ensure work efficiency.

[0027] 5. The present invention is equipped with rollers, which can ensure that the distance between the moving frame and the wall is the same each time, so that the cleaning effect of the front wall is consistent. This effectively avoids the phenomenon that the cleaning effect of some walls is not ideal due to the uneven distance between the moving frame and the front wall, and is conducive to ensuring work efficiency.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figures 1-8 As shown, its structural relationship is as follows: it includes a movable frame 1, a spray frame 2, and a decontamination mechanism 3;

[0040] The spray frame 2 is installed on the upper end of the movable frame 1 and is connected to the water source. The spray frame 2 has spray nozzles, and the washing and disinfection mechanism 3 is installed on the front side of the movable frame 1.

[0041] The decontamination mechanism 3 includes a waterproof motor 31, a motor bracket 32, a transmission assembly 33, a transmission shaft 34, a sliding frame 35, a support spring 36, and a cleaning sponge 37. The waterproof motor 31 is mounted and fixed on the motor bracket 32, and its output end is connected to the transmission assembly 33. The motor bracket 32 ​​is mounted and fixed on the movable frame 1. The transmission assembly 33 is connected to the output end of the waterproof motor 31 and the transmission shaft 34. The sliding frame 35 is mounted on the transmission shaft 34. The support spring 36 is installed between the transmission shaft 34 and the sliding frame 35. A cleaning sponge 37 is installed on the outside of the sliding frame 35.

[0042] The staff starts the waterproof motor 31. The waterproof motor 31 rotates, which drives the transmission component 33 installed at the output end to rotate. The transmission shaft 34 connected to the transmission component 33 also rotates together. The sliding frame 35 installed on the transmission shaft 34 drives the outer cleaning sponge 37 to rotate. At this time, the cleaning sponge 37 cleans the wall in front. When the sliding frame 35 rotates to a certain angle, it can squeeze the cleaning sponge 37 together with the wall in front of the cleaning sponge 37. Subsequently, the water inside the cleaning sponge 37 is squeezed out. The cleaning sponge 37 can repeatedly clean the wall in front, which helps to ensure work efficiency.

[0043] Preferably, the number of drive shaft 34, sliding frame 35, support spring 36 and cleaning sponge 37 of the decontamination mechanism 3 is not less than two.

[0044] This setting can improve cleaning results and increase work efficiency.

[0045] Preferably, it also includes a swing plate mechanism 4, which includes a swing plate 41, a slide rod 42, a bent rod 43, a locking structure, and a return spring 45. The swing plate 41 is mounted on the movable frame 1, and the slide rod 42 and the bent rod 43 are fixedly connected. One end of the slide rod 42 and the bent rod 43 are mounted on the swing plate 41, and the other end is mounted on the movable frame 1. The bent rod 43 has a waist-shaped groove. The return spring 45 is mounted on the movable frame 1, and one end of it is fixedly connected to the slide rod 42.

[0046] When the staff moves the moving frame 1 to the corner of the wall, the swing plate 41 is squeezed and the slide rod 42 installed on the swing plate 41 slides backward. At the same time, the return spring 45 behind the slide rod 42 is compressed to a suitable distance and then stops. This distance is such that the swing plate 41 is close to the wall. This setting can facilitate the cleaning and disinfection mechanism 3 to clean the corner of the wall and is conducive to ensuring work efficiency.

[0047] Preferably, the locking structure of the swing plate mechanism 4 includes a locking nut 44, which passes through the waist-shaped groove opened on the bent rod 43 and is installed and connected to the movable frame 1.

[0048] The worker rotates the locking nut 44 to lock the bent rod 43. At the same time, the slide rod 42 fixed to the bent rod 43 is also locked, so that the swing plate 41 cannot move. This prevents the slide rod 42 from being affected by the elastic force of the return spring 45 behind it, which is conducive to ensuring work efficiency.

[0049] Preferably, it also includes a corner cleaning mechanism 5, which includes a corner cleaning frame 51, a flow guide 52, a sealing block 53, and a fixed threaded frame 54. The corner cleaning frame 51 is installed on the swing plate 41, the flow guide 52 is fixedly connected to the corner cleaning frame 51 and communicates with it, the sealing block 53 is slidably connected to the flow guide 52, the sealing block 53 has a thread inside, one end of the fixed threaded frame 54 is threadedly connected to the sealing block 53, and the other end is fixedly connected to the spray frame 2.

[0050] Preferably, the sealing block 53 has a through hole and its lower end is connected to a water source.

[0051] During the rotation of the swing plate 41, the corner cleaning rack 51 installed above the swing plate 41 rotates, driving the guide connector 52 to rotate. At this time, the sealing block 53 moves downward along the fixed threaded frame 54, and the through hole on the sealing block 53 is exposed. Water is injected into the guide connector 52 through the through hole on the sealing block 53. Then, it flows into the corner cleaning rack 51 through the guide connector 52. Finally, it is sprayed from the corner cleaning rack 51 to the corner of the wall. This setting allows water to be discharged when the corner needs to be cleaned, and will not discharge water at other times, which is beneficial to ensuring work efficiency and controlling costs.

[0052] Preferably, it also includes a baffle mechanism 6, which includes a sealing plate 61, a guide block 62 and a connecting spring 63; the sealing plate 61 and the guide block 62 are slidably connected, the guide block 62 is installed on the spray frame 2, the upper end of the connecting spring 63 is connected to the sealing plate 61, and the lower end is connected to the sealing block 53.

[0053] As the sealing block 53 moves downward, it drives the connecting spring 63 above to move downward. The connecting spring 63 drives the sealing plate 61 above to move downward along the guide block 62, blocking the upper spray nozzles of the spray rack 2, leaving only the spray nozzles for cleaning the corners. Water is sprayed from the left-out spray nozzles to the corners, greatly increasing the corner cleaning efficiency and helping to ensure work efficiency.

[0054] Preferably, it also includes a guide mechanism 7, which includes a swing rod 71, a fixed block 72, a limiting block 73, a rotating rod 74, a contact rod 75, a pressing rod 76, a rotating disk 77, a guide block 78, and a protrusion 79. There are two swing rods 71 ​​and two fixed blocks 72. The fixed blocks 72 are respectively fixed to the sides of the movable frame 1 and the swing plate 41. One end of the two swing rods 71 ​​is respectively installed and connected to the two fixed blocks 72, and the other end is installed and connected to the limiting block 73. The rotating rod 74 is installed on the transmission shaft 34 and is slidably connected to the limiting block 73. The contact rod 75 is slidably connected to the rotating rod 74. One end of the pressing rod 76 is installed and connected to the upper end of the contact rod 75, and the other end is installed and connected to the sealing plate 61. The rotating disk 77 is installed above the sliding frame 35, and the rotating disk 77 is provided with a guide block 78 and a protrusion 79.

[0055] The sealing plate 61 descends, causing the pressure rod 76 to descend. The pressure rod 76 then causes the contact rod 75 to descend. The lower end of the contact rod 75 abuts against the guide block 78. The drive shaft 34 rotates, causing the sliding frame 35 to rotate. The rotating disk 77 mounted on the sliding frame 35 rotates. During the rotation of the rotating disk 77, the contact rod 75 moves along the guide block 78 and the protrusion 79 to the outside of the rotating disk 77, making the rotating disk 77 closer to the corner of the wall. This increases the cleaning effect of the cleaning sponge 37 below the rotating disk 77 on the corner of the wall, which is beneficial to ensuring work efficiency.

[0056] Preferably, it also includes rollers 8, which are installed in an array on the front side of the movable frame 1 and located between the washing and disinfection mechanisms 3.

[0057] This setting ensures that the distance between the movable frame 1 and the wall is the same each time, so that the cleaning effect of the decontamination mechanism 3 on the wall in front is consistent. It avoids the problem of uneven cleaning effect on some walls due to inconsistent distances between the movable frame 1 and the wall in front, which is conducive to ensuring work efficiency.

[0058] A decontamination method for post-disaster chemical sites, using the aforementioned post-disaster chemical site decontamination device, includes the following steps:

[0059] Step 1: The staff starts the waterproof motor 31. The waterproof motor 31 rotates, which drives the transmission component 33 installed at the output end to rotate. The transmission shaft 34 connected to the transmission component 33 also rotates together. The sliding frame 35 installed on the transmission shaft 34 drives the cleaning sponge 37 on the outside to rotate. At this time, the cleaning sponge 37 cleans the wall in front. When the sliding frame 35 rotates to a certain angle, it can squeeze the cleaning sponge 37 together with the wall in front of the cleaning sponge 37, squeezing out the water inside the cleaning sponge 37. The cleaning sponge 37 continues to rotate, and then the staff cleans the entire wall.

[0060] Step 2: The staff moves the moving frame 1 to the corner of the wall. At this time, the swing plate 41 is squeezed and the slide rod 42 installed on the swing plate 41 slides backward. At the same time, the return spring 45 behind the slide rod 42 is compressed until the swing plate 41 is pressed against the wall. Then, the staff rotates the locking nut 44 to lock the bent rod 43. The slide rod 42 fixed to the bent rod 43 is locked at the same time, so that the swing plate 41 cannot move.

[0061] Step 3: During the rotation of the swing plate 41, the corner cleaning rack 51 installed above the swing plate 41 rotates, which drives the flow guide 52 to rotate. At this time, the sealing block 53 moves downward along the fixed threaded frame 54, and the through hole on the sealing block 53 is exposed. Water is injected into the flow guide 52 through the through hole on the sealing block 53. Then, it flows into the corner cleaning rack 51 through the flow guide 52. Finally, it is sprayed from the corner cleaning rack 51 to the corner of the wall.

[0062] Step 4: As the sealing block 53 moves downward, it drives the connecting spring 63 above to move downward. The connecting spring 63 drives the sealing plate 61 above to move downward along the guide block 62, blocking the upper spray nozzles of the spray rack 2, leaving only the spray nozzles for cleaning the corners. Water sprays from the left-out spray nozzles to the corners of the wall.

[0063] Step 5: The sealing plate 61 descends, causing the pressure rod 76 to descend. The pressure rod 76 then causes the contact rod 75 to descend. The lower end of the contact rod 75 abuts against the guide block 78. The drive shaft 34 rotates, causing the sliding frame 35 to rotate. The rotating disk 77 mounted on the sliding frame 35 rotates. As the rotating disk 77 rotates, the contact rod 75 moves along the guide block 78 and the protrusion 79 to the outside of the rotating disk 77, making the rotating disk 77 closer to the corner of the wall. The cleaning sponge 37 under the rotating disk 77 can then fit more closely to the corner of the wall, increasing the cleaning effect until the cleaning is complete.

Step 2: The staff moves the moving frame (1) to the corner of the wall. At this time, the swing plate (41) is squeezed and the slide rod (42) installed on the swing plate (41) slides backward. At the same time, the return spring (45) behind the slide rod (42) is compressed until the swing plate (41) is pressed against the wall. Then, the staff rotates the locking nut (44) to lock the bent rod (43). The slide rod (42) fixed to the bent rod (43) is locked at the same time, so that the swing plate (41) cannot move. Step 3: During the rotation of the swing plate (41), the corner cleaning rack (51) installed above the swing plate (41) rotates, which drives the flow guide (52) to rotate. At this time, the sealing block (53) moves downward along the fixed threaded frame (54), and the through hole on the sealing block (53) is exposed. Water is injected into the flow guide (52) through the through hole on the sealing block (53). Then, it flows into the corner cleaning rack (51) through the flow guide (52). Finally, it is sprayed from the corner cleaning rack (51) to the corner of the wall. Step 4: As the sealing block (53) moves downward, it drives the connecting spring (63) above to move downward. The connecting spring (63) drives the sealing plate (61) above to move downward along the guide block (62), blocking the upper spray nozzles of the spray rack (2) and leaving only the spray nozzles for cleaning the corners. Water sprays from the left-out spray nozzles to the corners of the wall. Step 5: The sealing plate (61) descends, causing the pressure rod (76) to descend. The pressure rod (76) causes the contact rod (75) to descend. The lower end of the contact rod (75) abuts against the guide block (78). The drive shaft (34) rotates, causing the sliding frame (35) to rotate. The rotating disk (77) mounted on the sliding frame (35) rotates. During the rotation of the rotating disk (77), the contact rod (75) moves along the guide block (78) and the protrusion (79) to the outside of the rotating disk (77), making the rotating disk (77) closer to the corner of the wall. The cleaning sponge (37) under the rotating disk (77) can fit closer to the corner of the wall, increasing the cleaning effect on the corner of the wall until the cleaning is completed.
