Description

Technical Field

[0001] This invention relates to the field of fire extinguishing equipment technology, specifically to an inhibitor spraying device. Background Technology

[0002] Spontaneous combustion of coal is one of the major hazards in coal mines. Currently, one of the common measures to prevent spontaneous combustion of coal is to spray inhibitors into areas such as goafs and coal walls.

[0003] In the prior art, in order to reduce the labor intensity of workers and improve the degree of automation, an automatic preparation device for inhibitor slurry is usually set up, so that workers only need to control the spraying position of the inhibitor slurry.

[0004] However, the direction of the spray nozzles still needs to be manually controlled to ensure that the slurry is sprayed to the right position. When controlling the direction of the nozzles, workers need to drag the pipes that transport the slurry and overcome the reaction force when the slurry is sprayed out, which still makes the workers have a high labor intensity. In addition, the degree of automation is low and there are certain safety risks.

[0005] Therefore, a new inhibitor spraying device is needed. Summary of the Invention

[0006] This invention provides an inhibitor spraying device, which has a high degree of automation and high flexibility in adjusting the spraying position and spraying angle of the nozzle, ensuring good spraying coverage of each area and strong applicability.

[0012] Optionally, the first telescopic arm and the second telescopic arm are rotatably connected, and the moving adjustment mechanism further includes a first rotation drive member, which is connected to the second telescopic arm to drive the second telescopic arm to rotate about a rotation axis perpendicular to the first direction; A support arc block is provided at the connection between the first telescopic arm and the second telescopic arm, and a receiving groove suitable for accommodating the conveying pipe is provided on the arc-shaped surface of the support arc block.

The rotation adjustment mechanism further includes a first adjustment drive and a second adjustment drive. The first adjustment drive is connected to the first hinge to drive the first hinge to rotate around a first rotation axis. The second adjustment drive is connected to the second hinge to drive the second hinge to rotate around a second rotation axis. The first rotation axis and the second rotation axis are not parallel to each other.

[0015] Optionally, it also includes a pipe protection chamber, which has a receiving chamber formed inside to accommodate the conveying pipe, and the pipe protection chamber is connected to the first telescopic arm.

[0021] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to abutment; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] This invention provides an inhibitor spraying device, see below. Figures 1 to 3 The system includes a mixing unit 1, a spraying unit 2, and a mobile chassis 3. The mixing unit 1 is used to prepare the inhibitor slurry. The spraying unit 2 includes a feed pipe 21 connected to the slurry outlet of the mixing unit 1, a feed pump 211, a nozzle 22 connected to the feed pipe 21, and an adjustment mechanism for adjusting the nozzle 22. The adjustment mechanism includes a moving adjustment mechanism that can move the nozzle 22 and a rotating adjustment mechanism that can rotate the nozzle 22. The moving adjustment mechanism is configured to move the nozzle 22 within a space. The rotating adjustment mechanism is located at the end of the moving adjustment mechanism and is configured to rotate the nozzle 22 around at least two non-parallel axes, thus allowing the nozzle 22 to have a large rotation adjustment range and high flexibility. Both the mixing unit 1 and the spraying unit 2 are mounted on the mobile chassis 3, which moves them via the chassis 3. The mobile chassis 3 can be a wheeled chassis or a tracked chassis (e.g., a wheeled chassis or a tracked chassis). Figure 7 As shown in the figure, it is provided with a support platform 31 for connection with the mixing unit 1 and the spraying unit 2.

[0024] Based on the above structure, the inhibitor spraying device provided by the present invention, by setting a mixing unit 1, eliminates the need for manual mixing of inhibitor slurry. The mixed inhibitor slurry is pumped by a feed pump 211 through a conveying pipe 21 to the nozzle 22 for spraying, thereby improving the degree of automation and work efficiency. The movable adjustment mechanism moves the nozzle 22 in space, adjusting its vertical height and horizontal position, thus flexibly adjusting the nozzle 22 to the vicinity of the area to be sprayed, ensuring comprehensive spraying of the area. The rotating adjustment mechanism can flexibly adjust the spraying direction of the nozzle 22, enabling precise spraying of each position to be sprayed in complex spaces, thereby improving the applicability of the inhibitor spraying device and ensuring good spraying quality. In addition, the movable chassis 3 can move the mixing unit 1 and the spraying unit 2, eliminating the need for manual pulling of the mixing unit 1 and the spraying unit 2, resulting in higher automation and higher work efficiency.

[0025] Further, see Figures 4 to 6The mixing unit 1 includes an inhibitor storage chamber 11, a water tank 12, and a mixing chamber 13. The inhibitor storage chamber 11 is used to store inhibitor powder. The upper part of the inhibitor storage chamber 11 is provided with an openable and closable feed port to replenish the inhibitor powder into the inhibitor storage chamber 11. The lower part of the inhibitor storage chamber 11 may be provided with a discharge port to allow the inhibitor powder to be output from the inhibitor storage chamber 11. The water tank 12 can store clean water, and the upper part of the water tank 12 may also be provided with an openable and closable feed port to replenish the clean water into the water tank 12. The inhibitor storage chamber 11 and the water tank 12 are both connected to the mixing chamber 13 to respectively supply inhibitor powder and water into the mixing chamber 13. The mixing chamber 13 is equipped with a stirring device 14 to stir the water, inhibitor powder and water entering the mixing chamber 13 to produce an inhibitor slurry. The slurry outlet 131 at the bottom of the mixing chamber 13 is the slurry outlet end. The stirring device 14 includes a stirring rod 141 and a stirring motor 142. The stirring rod 141 is located inside the mixing chamber 13, and one end of the stirring rod 141 can extend out from the bottom of the mixing chamber 13 to be connected to the stirring motor 142 for transmission, so that the stirring motor 142 drives the stirring rod 141 to rotate. The sealing between the stirring rod and the mixing chamber 13 adopts the existing technology, which will not be described in detail here.

[0026] Furthermore, the inhibitor storage bin 11 and the mixing box 13 are connected via a screw feeder 15. One end of the screw feeder 15 is connected to the discharge port at the bottom of the inhibitor storage bin 11, and the other end is connected to the feed port at the top of the mixing box 13. The inhibitor powder is conveyed via the screw feeder 15. The amount of inhibitor powder conveyed can be controlled by controlling the rotation angle of the motor in the screw feeder 15, so as to achieve precise control of the amount of inhibitor powder conveyed, thereby facilitating precise control of the ratio of inhibitor slurry and ensuring that the ratio of inhibitor slurry is within the preset range.

[0027] Furthermore, the water tank 12 and the mixing tank 13 are connected via a water supply pipe 16 and a water pump 17. The water pump 17 draws water from the water tank 12 and delivers it to the mixing tank 13 via the water supply pipe 16. The water supply pipe 16 is equipped with a flow detector 18, which can detect the amount of water supplied to the mixing tank 13. The flow detector 18 can then control the on / off state of the water pump 17 based on the detected water volume. When the amount of water supplied to the mixing tank 13 reaches a preset value, the water pump 17 can be shut off to achieve precise control of the water injection volume. This facilitates precise control of the inhibitor slurry ratio, ensuring that the inhibitor slurry ratio is within a preset range. The water pump 17 is implemented using a controller, which is existing technology and will not be described in detail here.

[0028] In addition, see Figures 8 to 11The movable adjustment mechanism includes a first telescopic arm 23 and a second telescopic arm 24. The second telescopic arm 24 is connected to the telescopic end of the first telescopic arm 23, and the nozzle 22 is connected to the telescopic end of the second telescopic arm 24. The first telescopic arm 23 can drive the second telescopic arm 24 to move along a first direction, and the second telescopic arm 24 can drive the nozzle 22 to move along a second direction. The first direction and the second direction intersect. Specifically, the first direction can be a vertical direction, and the second direction can be a horizontal direction, thereby realizing the vertical height adjustment and horizontal position adjustment of the nozzle 22. This allows the nozzle 22 to be flexibly adjusted to the vicinity of the area to be sprayed, thus ensuring that the area is fully sprayed.

[0029] Furthermore, the first telescopic arm 23 and the second telescopic arm 24 can be rotatably connected. The moving adjustment mechanism also includes a first rotation drive 25, which is connected to the second telescopic arm 24 to drive the second telescopic arm 24 to rotate around a pivot perpendicular to the first direction. Specifically, a hinge shaft can be provided on the second telescopic arm 24, and a hinge seat can be provided on the first telescopic arm 23 to hinge the first telescopic arm 23 and the second telescopic arm 24. The second telescopic arm 24 is synchronously rotatably connected to the hinge shaft and connected to the first rotation drive 25 through the hinge shaft. This allows the first rotation drive 25 to drive the second telescopic arm 24 to rotate around a pivot perpendicular to the first direction, that is, to drive the second telescopic arm 24 to pitch up and down, thereby achieving height adjustment of the nozzle 22.

[0030] The conveying pipe 21 can be arranged along the supporting platform 31 and extend to the spraying unit 2, and then connected to the nozzle 22. The part of the conveying pipe 21 located at the spraying unit 2 is a redundant length section. A supporting arc block 26 is provided at the external corner of the connection between the first telescopic arm 23 and the second telescopic arm 24. An arc surface is formed on the supporting arc block 26. The arc surface can be a quarter-circle arc surface. Its center can be set at the hinge axis where the first telescopic arm 23 and the second telescopic arm 24 are hinged. A receiving groove suitable for accommodating the conveying pipe 21 is provided on the arc surface of the supporting arc block 26. The conveying pipe 21 is arranged along the side where the external corner of the connection between the first telescopic arm 23 and the second telescopic arm 24 is located, so that the receiving groove can provide constraint on the conveying pipe 21. During the relative rotation of the first telescopic arm 23 and the second telescopic arm 24, the conveying pipe 21 is not easily caught between the first telescopic arm 23 and the second telescopic arm 24, thereby avoiding the situation where the conveying pipe 21 is crushed.

[0031] Furthermore, the first telescopic arm 23 can be rotatably connected to the support platform 31 of the mobile chassis 3. The moving adjustment mechanism also includes a second rotation drive 27, which is connected to the first telescopic arm 23 to drive the second telescopic arm 24 to rotate around a first direction. Specifically, the bottom of the first telescopic arm 23 and the support platform 31 can be rotatably connected by a shaft and bearing seat, and a gear structure is provided at the bottom of the first telescopic arm 23. The second rotation drive 27 can be a rotating motor connected to the support platform 31, and the output end of the second rotation drive 27 is provided with a gear that matches the gear structure at the bottom of the first telescopic arm 23, thereby driving the first telescopic arm 23 to rotate. Or as... Figure 1 and Figure 9 As shown, the second rotation drive 27 is mounted on the support platform 31, and a protective cover 5 is provided on the outside of the second rotation drive 27. The bottom of the first telescopic arm 23 and the protective cover 5 can be rotatably connected through a bearing. The output end of the second rotation drive 27 is directly connected to the bottom of the first telescopic arm 23, thereby driving the first telescopic arm 23 to rotate.

[0032] Furthermore, the rotation adjustment mechanism includes a first hinge 281 and a second hinge 282. One end of the first hinge 281 is hinged to the second telescopic arm 24, and the other end is hinged to the second hinge 282. The nozzle 22 is connected to the end of the second hinge 282 away from the first hinge 281. The rotation adjustment mechanism also includes a first adjustment drive 291 and a second adjustment drive 292. The first adjustment drive 291 is drivenly connected to the first hinge 281 to drive the first hinge 281 to rotate around the first rotation axis. The second adjustment drive 292 is drivenly connected to the second hinge 282 to drive the second hinge 282 to rotate around the second rotation axis. The first rotation axis and the second rotation axis are not parallel to each other, and the first rotation axis and the second rotation axis can be configured such that one of them extends in the vertical direction and the other extends in the horizontal direction, so that the spraying direction adjustment range of the nozzle 22 is wider.

[0033] Furthermore, such as Figure 12 As shown, the inhibitor spraying device of this application also includes a pipe protection chamber 4. The pipe protection chamber 4 has a receiving chamber formed inside, which is suitable for accommodating the conveying pipe 21, so as to protect the conveying pipe 21. The pipe protection chamber 4 should be configured to be connected to the first telescopic arm 23, so as to be able to rotate with the first telescopic arm 23 and reduce the pulling on the conveying pipe 21.

[0034] Furthermore, a pair of telescopic rods 41 are provided on opposite side walls inside the pipeline protection chamber 4. One end of the telescopic rod 41 is connected to the side wall, and the other end is provided with a roller 411 suitable for abutting against the conveying pipe 21. The telescopic rods 41, the first telescopic arm 23, and the second telescopic arm 24 are all hydraulic telescopic mechanisms. The rodless chambers of each telescopic rod 41 are connected to the rodless chambers of the first telescopic arm 23 and the second telescopic arm 24 through oil pipelines and hydraulic pumps. When oil is discharged from the rodless chambers of the first telescopic arm 23 and the second telescopic arm 24, oil enters the rodless chamber of the telescopic rod 41, and when oil is received from the rodless chambers of the first telescopic arm 23 and the second telescopic arm 24, oil is extracted from the rodless chambers of each telescopic rod 41. Thus, the rodless chambers of the telescopic rods 41 can be used as oil storage tanks, thereby eliminating the need for an oil storage tank or reducing the size of the oil storage tank. The size allows for the miniaturization and weight reduction of the inhibitor spraying device of this application. Furthermore, solenoid valves can be installed at the connection points between the rodless chamber of each telescopic rod 41 and the oil delivery pipe. The opening and closing of the solenoid valves, as well as the opening and closing sequence of each solenoid valve, can be controlled by a controller. Specifically, when oil is discharged from the rodless chamber of the telescopic rod 41, the solenoid valve corresponding to the upper telescopic rod 41 opens earlier than the solenoid valve corresponding to the lower telescopic rod 41. When oil is fed into the rodless chamber of the telescopic rod 41, the solenoid valve corresponding to the lower telescopic rod 41 opens earlier than the solenoid valve corresponding to the upper telescopic rod 41. This ensures that when the first telescopic arm 23 and the second telescopic arm 24 extend, the upper delivery pipe 21 extends first; and when the first telescopic arm 23 and the second telescopic arm 24 retract, the lower delivery pipe 21 folds and retracts first, thereby reducing the pulling on the delivery pipe 21.

[0035] Based on the above design, the inhibitor spraying device of this application, on the one hand, can improve the degree of automation and work efficiency by setting up a mixing unit 1, which eliminates the need for manual mixing of inhibitor slurry. The moving adjustment mechanism can move the nozzle 22 in space to adjust the vertical height and horizontal position of the nozzle 22, thereby flexibly adjusting the nozzle 22 to the vicinity of the area to be sprayed, thus ensuring comprehensive spraying of the area. The rotating adjustment mechanism can flexibly adjust the spraying direction of the nozzle 22, so as to accurately spray each position to be sprayed in complex spaces, thereby improving the applicability of the inhibitor spraying device and ensuring good spraying quality. In addition, the moving chassis 3 can drive the mixing unit 1 and the spraying unit 2 to move, thus eliminating the need for manual pulling of the mixing unit 1 and the spraying unit 2, resulting in a higher degree of automation and higher work efficiency.

[0036] On the other hand, by setting up a pipeline protection chamber 4 and telescopic rods 41 inside the chamber, and connecting the rodless chambers of each telescopic rod 41 with the rodless chambers of the first telescopic arm 23 and the second telescopic arm 24 through oil pipelines and hydraulic pumps, and by setting up solenoid valves at the connection between the rodless chambers of each telescopic rod 41 and the oil pipelines, and controlling the opening and closing of the solenoid valves and the opening and closing sequence of each solenoid valve, it is possible to achieve the following: when oil is discharged from the rodless chamber of the telescopic rod 41, the solenoid valve corresponding to the upper telescopic rod 41 opens earlier than the solenoid valve corresponding to the lower telescopic rod 41; when oil is fed into the rodless chamber of the telescopic rod 41, the solenoid valve corresponding to the lower telescopic rod 41 opens earlier than the solenoid valve corresponding to the upper telescopic rod 41. This ensures that when the first telescopic arm 23 and the second telescopic arm 24 extend, the upper conveying pipe 21 extends first, and when the first telescopic arm 23 and the second telescopic arm 24 retract, the lower conveying pipe 21 folds and retracts first, thereby reducing the pulling on the conveying pipe 21.

[0037] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. Furthermore, various different embodiments of the present invention can also be arbitrarily combined, as long as they do not violate the spirit of the present invention, and should also be regarded as the content disclosed by the present invention.
