Description

Technical Field

[0001] The present invention relates to the technical field of dust detection, and specifically to a foldable port dust detection device. Background Art

[0002] At present, the existing port dust detection devices cannot be folded, resulting in a large volume of the device and inconvenient flexible use. At the same time, when detecting dust, after dust particles are introduced into the air flow channel, a large amount of dust is likely to deposit in the air flow channel, ultimately reducing the accuracy of the dust sensor. Summary of the Invention

[0003] To achieve the above objectives, the present invention is realized through the following technical solutions: A foldable port dust detection device, comprising:

[0004] A frame, which has a supporting frame body. A rectangular notch is provided at the side of the frame, and wheels are installed at the top of the frame;

[0005] An adjustment mechanism, which is used to adjust the angle and fold. The adjustment mechanism is installed inside the frame;

[0006] Among them, the adjustment mechanism includes a support frame and a connecting round rod. The bottom of the support frame is fixedly installed at the middle of the bottom of the inner cavity of the frame. The two ends of the connecting round rod are rotatably installed on the corresponding two sides of the inner cavity of the frame. The connecting round rod is installed at a position close to the top of the frame. An electric telescopic rod is rotatably installed at the top of the support frame. Square connecting plates and trapezoidal support plates are respectively fixedly installed at the middle of the outer side of the connecting round rod. By extending the output end of the electric telescopic rod, a driving force can be applied to the square connecting plate. Under the rotational support of the connecting round rod, the trapezoidal support plate can be driven to rotate counterclockwise, and then the entire gas diversion mechanism can be driven to rotate counterclockwise. By using the gas diversion mechanism to rotate to the bottom position of the rectangular notch, the gas diversion mechanism can be hidden, thereby achieving the folding effect and reducing the overall center of gravity of the device;

[0007] This foldable port dust detection device further includes:

[0008] A gas diversion mechanism, which is used to detect dust in the gas. The gas diversion mechanism is installed on the top of the trapezoidal support plate;

[0009] Among them, the gas drainage mechanism includes a gas drainage cylinder. The bottom of the gas drainage cylinder is fixedly installed with the top end of a trapezoidal support plate. The air outlet end of the gas drainage cylinder is fixedly installed with a suction fan. A spiral blade is fixedly installed inside the gas drainage cylinder, and the spiral blade is installed at the air inlet end of the gas drainage cylinder. A curling plate is fixedly installed at the middle of the inner cavity bottom of the gas drainage cylinder. A dust concentration sensor is fixedly installed at the middle of the top of the gas drainage cylinder. The detection end of the dust concentration sensor extends into the interior of the gas drainage cylinder. An anti-backflow component is installed inside the gas drainage cylinder, and the anti-backflow component is installed between the curling plate and the suction fan. Using the suction force of the suction fan, at this time, external air forms an air flow, and the air flow carries dust and enters from the left end of the gas drainage cylinder. Under the flow of the gas, with the guidance of the spiral blade, the gas presents a swirling state, making it difficult for the dust to deposit, which helps with subsequent accurate detection. Under the drainage of the gas drainage cylinder, the air flow can carry the dust and continuously flow to the right side.

[0010] Preferably, both the electric telescopic rod and the square connecting plate are installed obliquely, which is convenient for the elongation of the output end of the electric telescopic rod to push and pull down the square connecting plate, and the square connecting plate is installed above the output end of the electric telescopic rod.

[0011] The contraction of the output end of the electric telescopic rod can be used to apply a pulling force to the right end of the square connecting plate. Under the rotational support of the connecting round rod, the connecting round rod can drive the trapezoidal support plate to rotate clockwise, and then the entire gas drainage mechanism can be driven to rotate and adjust the angle, which can increase the drainage range of the gas, and thus helps with the detection of dust. Through different states of the same structure, multiple functions can be achieved.

[0012] Preferably, rectangular holes are formed in the curling surface of the outer side of the curling plate. A reinforcing plate is fixedly installed between the bottom of the gas drainage cylinder and the outer side of the trapezoidal support plate. A cover plate is installed at the bottom of the gas drainage cylinder, and the cover plate is installed directly below the anti-backflow component. As the air flow continuously flows to the right side, when the air flow flowing out from the right end of the spiral blade encounters the curling plate, under the guidance of the curling plate, the dust carried by the air flow can present a vortex state, making the air flow continuously converge, and making the dust evenly dispersed in the air flow. Thus, it is not easy to have a situation where the dust carried by the local air flow is too much or too little. Combined with the rectangular holes evenly distributed on the curling surface of the outer side of the curling plate, the dust can be evenly discharged to the detection end of the dust concentration sensor extending into the interior of the gas drainage cylinder, making the detection of the dust by the detection end of the dust concentration sensor more accurate.

[0013] Preferably, the center line of the spiral blade coincides with the central axis of the gas diversion cylinder, and the position of the spiral blade corresponds to the position of the curling plate, facilitating the combined action of the spiral blade and the curling plate on the air flow.

[0014] Preferably, the anti-backflow component includes an annular partition and a conical plug. The outer edge of the annular partition is fixedly installed in the circular inner cavity of the gas diversion cylinder. The conical plug is installed at the center of the annular partition. A circular through hole is opened at the center of the annular partition. The conical tip of the conical plug passes through the center of the circular through hole. An annular extension flange is fixedly installed at the outer edge of the conical plug. A first spring is fixedly installed between the outer side of the annular extension flange and the outer side of the annular partition. The first springs are evenly distributed between the outer side of the annular extension flange and the outer side of the annular partition. A filter screen is fixedly installed in the circular inner cavity of the gas diversion cylinder. The filter screen is installed near the conical plug. As the gas blows onto the conical surface of the conical plug, at this time, the conical plug is subjected to a blowing force to the right by the gas, and combined with the annular extension flange increasing the contact area with the air flow, the conical plug is pushed to move to the right after being blown, and the first spring is stretched. By using the separation of the conical plug from the circular through hole at the center of the annular partition, the circular through hole is opened at this time, facilitating the gas flow, and enabling the filter screen to filter the dust in time, thereby treating the dust.

[0015] Preferably, the annular partition and the conical plug are installed at the same height. The first spring is arc-shaped. After the suction fan stops working, at this time, the suction stops, so that the blowing force of the air flow on the conical plug disappears, and under the elastic tension of the first spring, the conical plug moves to the left for reset, thereby blocking the circular through hole, and further making it difficult for the filtered dust to flow back.

[0016] Preferably, an auxiliary component is installed at the bottom of the inner cavity of the frame, and the auxiliary component is installed near the rectangular notch. The auxiliary component includes an arc-shaped notch and a housing. The arc-shaped notch is opened at the side of the outer side of the frame, and the arc-shaped notch is opened at the middle of the inner wall bottom of the rectangular notch. The bottom of the housing is at the side of the bottom of the inner cavity of the frame. At the corresponding positions at the top of the housing, bushing sleeves are fixedly installed. A support guide post is slidably installed at the center of the bushing sleeve. The top of the support guide post is installed with a clamping module. The bottom end of the support guide post extends into the interior of the housing. A connecting flat plate is fixedly installed at the bottom end of the support guide post. A second spring is fixedly installed between the bottom of the connecting flat plate and the bottom of the inner cavity of the housing.

[0017] Preferably, the position of the arc-shaped notch corresponds to the position of the clamping module. The support guide posts are provided in two, and the two support guide posts are symmetrically installed along the middle of the housing.

[0018] Preferably, the clamping module includes an arc-shaped clamping plate. The bottom of the arc-shaped clamping plate is fixedly connected to the top end of the support guide post. A first flexible strip and a second flexible strip are respectively and fixedly installed at the arc-shaped concave surface on the outer side of the arc-shaped clamping plate. A limiting ball is fixedly installed at the top end of the arc-shaped clamping plate. When the whole gas diversion mechanism is driven to rotate counterclockwise for folding, when the gas diversion cylinder is driven by the trapezoidal support plate to rotate to the bottom position, the gas diversion cylinder is located at the position of the arc-shaped notch, and it is not easy to have the situation of structural jamming.

[0019] By applying a downward pressing force to the clamping module at the port of the gas diversion cylinder, and under the elastic force of the second spring, the support guide post receives a reverse acting force, and the bottom of the gas diversion cylinder is lifted by the arc-shaped clamping plate. Moreover, since the limiting balls are located on both sides of the gas diversion cylinder, the gas diversion cylinder is limited and not easy to shake randomly, making the connection between the structures more firm after folding.

[0020] Preferably, both the first flexible strip and the second flexible strip are arc-shaped, and the materials of the first flexible strip, the second flexible strip, and the limiting ball are all rubber materials.

[0021] The present invention provides a folding port dust detection device. It has the following beneficial effects:

[0022] First, for this folding port dust detection device, by the elongation of the output end of the electric telescopic rod, a pushing force can be applied to the square connecting plate. Under the rotational support of the connecting round rod, the trapezoidal support plate can be driven to rotate counterclockwise, and then the whole gas diversion mechanism can be driven to rotate counterclockwise. By using the gas diversion mechanism to rotate to the bottom position of the rectangular notch to hide the gas diversion mechanism, the folding effect is realized, and the overall center of gravity of the device is reduced.

[0023] Second, for this folding port dust detection device, by the contraction of the output end of the electric telescopic rod, a pulling force is applied to the right end of the square connecting plate. Under the rotational support of the connecting round rod, the connecting round rod can drive the trapezoidal support plate to rotate clockwise, and then the whole gas diversion mechanism can be driven to rotate and adjust the angle, which can increase the gas diversion range and thus contribute to the detection of dust. Through different states of the same structure, multiple functions are realized.

[0024] Third, for this folding port dust detection device, by the suction of the suction fan, at this time, the outside air forms an air flow, and the air flow carries dust and enters from the left end of the gas diversion cylinder. Under the guidance of the spiral blades with the gas flow, the gas presents a swirling state, making the dust not easy to deposit, which thus contributes to the subsequent accurate detection. Under the diversion of the gas diversion cylinder, the air flow can carry the dust and continuously flow to the right.

[0025] 4. For this foldable port dust detection device, under the guidance of the curling plate, the dust carried by the air flow can be made to present a vortex shape, causing the air flows to continuously converge, enabling the dust to be evenly dispersed in the air flow. As a result, it is not easy to have situations where the dust carried by the local air flow is either too much or too little. Moreover, combined with the rectangular holes being evenly distributed at the curling surface outside the curling plate, the dust can be evenly discharged towards the detection end of the dust concentration sensor extending into the gas diversion cylinder, making the detection of the dust by the detection end of the dust concentration sensor more accurate.

[0026] 5. For this foldable port dust detection device, as the conical plug is blown by the air flow and combined with the annular extended flange increasing the contact area with the air flow, the conical plug is blown and moves to the right. By separating the conical plug from the circular through-hole at the center of the annular partition, the circular through-hole is opened at this time, facilitating the gas flow, and enabling the filter screen to filter the dust in a timely manner, thereby processing the dust.

[0027] 6. For this foldable port dust detection device, when the blowing force of the air flow on the conical plug disappears and under the elastic tension of the first spring, the conical plug moves to the left for reset, thereby blocking the circular through-hole, and making it not easy for the filtered dust to flow back.

[0028] 7. For this foldable port dust detection device, the port of the gas diversion cylinder exerts a downward pressing force on the clamping module, and under the elastic force of the second spring, the support guide post receives a reverse acting force, and the bottom of the gas diversion cylinder is lifted by the arc-shaped clamping plate. Moreover, with the limiting balls on both sides of the gas diversion cylinder, the gas diversion cylinder is limited and not easy to shake randomly, making the connection between the structures more firm after folding.

Specific embodiments

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0041] The first embodiment is as Figures 1-3 shown. The present invention provides a technical solution: a foldable port dust detection device, including:

[0042] A rack 1, which has a supporting frame body. A rectangular notch 2 is opened at the side of the rack 1, and wheels 3 are installed on the top of the rack 1;

[0043] Adjusting mechanism 4, which is used to adjust the angle and fold. The adjusting mechanism 4 is installed inside the frame 1;

[0044] Among them, the adjusting mechanism 4 includes a support frame 41 and a connecting round rod 42. The bottom of the support frame 41 is fixedly installed at the middle of the bottom cavity of the frame 1. The two ends of the connecting round rod 42 are rotatably installed on the corresponding two sides of the inner cavity of the frame 1. The connecting round rod 42 is installed near the top of the frame 1. An electric telescopic rod 43 is rotatably installed at the top of the support frame 41. Square connecting plates 44 and trapezoidal support plates 45 are respectively fixedly installed at the middle of the outer side of the connecting round rod 42. When the staff turns on the electric telescopic rod 43 to work, by using the elongation of the output end of the electric telescopic rod 43, a driving force can be applied to the square connecting plate 44, and under the rotational support of the connecting round rod 42, the trapezoidal support plate 45 can be driven to rotate counterclockwise, and then the whole gas diversion mechanism 5 can be driven to rotate counterclockwise, and by using the gas diversion mechanism 5 to rotate to the bottom position of the rectangular notch 2, the gas diversion mechanism 5 can be hidden, thus achieving the folding effect;

[0045] Both the electric telescopic rod 43 and the square connecting plate 44 are installed obliquely, which is convenient for the elongation of the output end of the electric telescopic rod 43 to push and pull the square connecting plate 44, and the square connecting plate 44 is installed above the output end of the electric telescopic rod 43.

[0046] When the staff turns on the electric telescopic rod 43 to work, the contraction of the output end of the electric telescopic rod 43 can be used to apply a pulling force to the right end of the square connecting plate 44, and under the rotational support of the connecting round rod 42, the connecting round rod 42 can be driven to drive the trapezoidal support plate 45 to rotate clockwise, and then the whole gas diversion mechanism 5 can be driven to rotate to adjust the angle, which can increase the gas diversion range and thus contribute to the detection of dust.

[0047] Second embodiment, as Figures 1-7 shown, on the basis of the first embodiment:

[0048] This folding port dust detection device further includes:

[0049] A gas diversion mechanism 5, which is used to detect the dust in the gas. The gas diversion mechanism 5 is installed on the top of the trapezoidal support plate 45;

[0050] Among them, the gas drainage mechanism 5 includes a gas drainage cylinder 51. The bottom of the gas drainage cylinder 51 is fixedly installed with the top end of the trapezoidal support plate 45. The air outlet end of the gas drainage cylinder 51 is fixedly installed with a suction fan 52. A spiral blade 53 is fixedly installed inside the gas drainage cylinder 51, and the spiral blade 53 is installed at the air inlet end of the gas drainage cylinder 51. A curling plate 54 is fixedly installed at the middle of the inner cavity bottom of the gas drainage cylinder 51. A dust concentration sensor 55 is fixedly installed at the middle of the top of the gas drainage cylinder 51. The detection end of the dust concentration sensor 55 extends into the gas drainage cylinder 51. An anti-backflow component 56 is installed inside the gas drainage cylinder 51, and the anti-backflow component 56 is installed between the curling plate 54 and the suction fan 52. The staff turns on the suction fan 52 to work. Using the suction of the suction fan 52, at this time, the outside air forms an air flow, and the air flow carries dust and enters from the left end of the gas drainage cylinder 51. Under the flow of the gas, with the guidance of the spiral blade 53, the gas presents a swirling state, making it difficult for the dust to deposit, which helps with subsequent accurate detection. Under the drainage of the gas drainage cylinder 51, the air flow can carry the dust and continuously flow to the right side.

[0051] The model of the dust concentration sensor 55 is: LBT-GCG1000. It uses the principle of light refraction to detect dust. The microprocessor operates on the detection data to directly display the dust mass concentration and convert it into a data signal for output.

[0052] A rectangular hole 57 is opened at the curling surface outside the curling plate 54. A reinforcing plate 58 is fixedly installed between the bottom of the gas drainage cylinder 51 and the outside of the trapezoidal support plate 45. A cover plate 59 is installed at the bottom of the gas drainage cylinder 51, and the cover plate 59 is installed directly below the anti-backflow component 56. As the air flow continuously flows to the right side, when the air flow flowing out from the right end of the spiral blade 53 encounters the curling plate 54, under the guidance of the curling plate 54, the dust carried by the air flow can present a swirling state, making the air flow continuously converge, making the dust evenly dispersed in the air flow. Thus, it is not easy to have the situation where the dust carried by the local air flow is too much or too little. Combined with the rectangular holes 57 evenly distributed on the curling surface outside the curling plate 54, the dust can be evenly discharged to the detection end of the dust concentration sensor 55 extending into the gas drainage cylinder 51, making the detection of the dust by the detection end of the dust concentration sensor 55 more accurate.

[0053] The central axis of the spiral blade 53 coincides with the central axis of the gas drainage cylinder 51. The position of the spiral blade 53 corresponds to the position of the curling plate 54, which is convenient for the spiral blade 53 and the curling plate 54 to act on the air flow together.

[0054] The anti-backflow component 56 includes an annular partition 561 and a conical plug 562. The outer edge of the annular partition 561 is fixedly installed with the circular inner cavity of the gas drainage cylinder 51. The conical plug 562 is installed at the center of the annular partition 561. A circular through-hole 563 is provided at the center of the annular partition 561. The conical tip of the conical plug 562 passes through the center of the circular through-hole 563. An annular extended flange 564 is fixedly installed at the outer edge of the conical plug 562. A first spring 565 is fixedly installed between the outer side of the annular extended flange 564 and the outer side of the annular partition 561. The first springs 565 are evenly distributed between the outer side of the annular extended flange 564 and the outer side of the annular partition 561. A filter screen 566 is fixedly installed in the circular inner cavity of the gas drainage cylinder 51. The filter screen 566 is installed at a position close to the conical plug 562. As the gas blows onto the conical surface of the conical plug 562, at this time, the conical plug 562 is subjected to a blowing force to the right by the gas, and combined with the annular extended flange 564 increasing the contact area with the air flow, the conical plug 562 is blown and moves to the right, and the first spring 565 is stretched. By using the separation of the conical plug 562 from the circular through-hole 563 at the center of the annular partition 561, the circular through-hole 563 is opened at this time, facilitating the gas flow, and enabling the filter screen 566 to filter the dust in time, thereby treating the dust.

[0055] The annular partition 561 and the conical plug 562 are installed at the same height. The first spring 565 is arc-shaped. After the suction fan 52 stops working, the suction stops at this time, causing the blowing force of the air flow on the conical plug 562 to disappear. Under the elastic pulling force of the first spring 565, the conical plug 562 moves to the left for reset, thereby blocking the circular through-hole 563, and further preventing the filtered dust from flowing back easily.

[0056] The third embodiment is as Figures 1-10 shown, based on the first embodiment and the second embodiment:

[0057] An auxiliary component 6 is installed at the bottom of the inner cavity of the frame 1, and the auxiliary component 6 is installed near the rectangular notch 2. The auxiliary component 6 includes an arc-shaped notch 61 and a housing 62. The arc-shaped notch 61 is opened at the side of the outer side of the frame 1 and is opened at the middle of the bottom inner wall of the rectangular notch 2. The bottom of the housing 62 is at the side of the bottom of the inner cavity of the frame 1, and bushing 63 is fixedly installed at the position corresponding to the top of the housing 62. A support guide post 64 is slidably installed at the center of the bushing 63. The top of the support guide post 64 is installed with a clamping module 65. The bottom end of the support guide post 64 extends into the interior of the housing 62. A connecting flat plate 66 is fixedly installed at the bottom end of the support guide post 64. A second spring 67 is fixedly installed between the bottom of the connecting flat plate 66 and the bottom of the inner cavity of the housing 62. When the entire gas drainage mechanism 5 is driven to rotate counterclockwise for folding, when the gas drainage cylinder 51 is driven by the trapezoidal support plate 45 to rotate to the bottom position, the gas drainage cylinder 51 is located at the position of the arc-shaped notch 61, and the situation of structural jamming is not likely to occur.

[0058] The position of the arc-shaped notch 61 corresponds to the position of the clamping module 65. Two support guide posts 64 are provided, and the two support guide posts 64 are symmetrically installed along the middle of the housing 62.

[0059] The clamping module 65 includes an arc-shaped clamping plate 651. The bottom of the arc-shaped clamping plate 651 is fixedly connected to the top end of the support guide post 64. A first flexible strip 652 and a second flexible strip 653 are respectively fixedly installed at the arc-shaped concave surface on the outer side of the arc-shaped clamping plate 651. A limiting ball 654 is fixedly installed at the top end of the arc-shaped clamping plate 651. By applying a downward pressing force on the clamping module 65 through the port of the gas drainage cylinder 51, and under the elastic force of the second spring 67, the support guide post 64 receives a reverse acting force, and the bottom of the gas drainage cylinder 51 is lifted by the arc-shaped clamping plate 651. And by using the limiting balls 654 on both sides of the gas drainage cylinder 51, the gas drainage cylinder 51 is limited, and the situation of random shaking is not likely to occur, making the connection between the structures more firm after folding.

[0060] Both the first flexible strip 652 and the second flexible strip 653 are arc-shaped. The materials of the first flexible strip 652, the second flexible strip 653, and the limiting ball 654 are all rubber materials.

[0061] During use, first, by the rolling of the wheels 3, the entire frame 1 is moved to the designated position at the port. The staff starts the electric telescopic rod 43 to work. By the contraction of the output end of the electric telescopic rod 43, a pulling force is applied to the right end of the square connecting plate 44. Under the rotational support of the connecting round rod 42, the connecting round rod 42 can drive the trapezoidal support plate 45 to rotate clockwise, and then the entire gas drainage mechanism 5 is driven to rotate and adjust the angle, which can increase the drainage range of the gas.

[0062] At this time, the staff turns on the suction fan 52 to work. Using the suction force of the suction fan 52, the outside air forms an air flow at this time, and the air flow carries dust and enters from the left end of the gas diversion cylinder 51. Under the flow of the gas, with the guidance of the spiral blade 53, the gas presents a swirling state, making it difficult for the dust to deposit, which helps the subsequent accurate detection. Under the diversion of the gas diversion cylinder 51, the air flow can carry the dust and continuously flow to the right;

[0063] And as the air flow continuously flows to the right, when the air flow flowing out from the right end of the spiral blade 53 encounters the curling plate 54, under the guidance of the curling plate 54, the dust carried by the air flow can present a vortex state, making the air flow continuously converge, and the dust is evenly dispersed in the air flow. Thus, it is not easy to have the situation that the dust carried by the local air flow is too much or too little. Combined with the rectangular holes 57 evenly distributed on the curling surface outside the curling plate 54, the dust can be evenly discharged to the detection end of the dust concentration sensor 55 extending into the gas diversion cylinder 51, making the detection of the dust by the detection end of the dust concentration sensor 55 more accurate;

[0064] And as the gas blows onto the conical surface of the conical plug 562, at this time, the conical plug 562 receives a blowing force to the right from the gas, and combined with the annular extending flanging 564 to increase the contact area with the air flow, the conical plug 562 is pushed to move to the right after being blown, and the first spring 565 is stretched. By using the separation of the conical plug 562 from the circular through hole 563 at the center of the annular partition 561, the circular through hole 563 is opened at this time, facilitating the gas flow, and enabling the filter screen 566 to filter the dust in time, thereby processing the dust;

[0065] After the dust detection is completed, the elongation of the output end of the electric telescopic rod 43 is used again to apply a pushing force to the square connecting plate 44. Under the rotational support of the connecting round rod 42, the trapezoidal support plate 45 can be driven to rotate counterclockwise, and then the entire gas diversion mechanism 5 can be driven to rotate counterclockwise. By using the gas diversion mechanism 5 to rotate to the bottom position of the rectangular notch 2, the gas diversion mechanism 5 is hidden, thereby achieving the folding effect;

[0066] And the port of the gas diversion cylinder 51 applies a downward pressing force to the clamping module 65. Under the elastic force of the second spring 67, the support guide post 64 receives a reverse acting force, and the bottom of the gas diversion cylinder 51 is lifted by the arc-shaped clamping plate 651. And by using the limit balls 654 on both sides of the gas diversion cylinder 51, the gas diversion cylinder 51 is limited and not prone to random shaking, making the connection between the structures more firm after folding;

[0067] Meanwhile, the operation of the suction fan 52 is stopped, and the blowing force of the air flow on the conical plug 562 disappears. Under the elastic tension of the first spring 565, the conical plug 562 moves to the left for reset, thereby blocking the circular through-hole 563, making it difficult for the filtered dust to flow back. Then, the cover plate 59 is opened, and the filtered dust can be cleaned up.
