Description

Technical Field

[0001] The present invention relates to the field of emergency rescue equipment, and particularly to a tank assembly and a suction truck. Background Art

[0002] In recent years, with the rapid development of urban construction in China, there have been more and more projects such as the construction of municipal pipeline projects for drainage, gas supply, power supply, etc. and the construction of foundation pits for construction. Accidents such as the collapse of various pipelines, foundation pits and ditches occur more frequently, and the rescue tasks of China's fire rescue teams for such accidents have increased year by year. The main problems existing in the current rescue are: the rescue is dangerous, and secondary collapses are likely to occur in the ditches. There is a need for a small, light and flexible suction rescue device. At present, the rescue equipment that can be applied to suction rescue is excavation suction vehicles. However, this type of suction vehicle needs to be equipped with a negative pressure suction device and a dust removal device, resulting in too large a volume of the whole vehicle and too large a volume of the material bin, resulting in too heavy a weight of the whole vehicle, which is very unsuitable for approaching the rescue site for rescue. There is a need for a small, light and fully functional suction rescue device with a combined tank to rescue the buried object.

[0003] At present, domestic vacuum suction products using negative pressure suction mainly focus on the field of municipal environmental sanitation sewage suction. Most of the tank structures are circular tanks. Suction pipelines, dust removal pipelines and dust removal bins need to be arranged on the tanks. The rear cover is opened and lifted for discharging, and the pipeline sizes are all very large, and the overall structure layout is very complicated. There are also similar excavation suction devices abroad. The tanks have two forms: circular tanks and square tanks. The circular tanks are similar to domestic products. The square tank structure is divided into several compartments, and complex suction pipelines are arranged on the top, with high requirements for sealing. The side of the square tank is turned over and lifted for discharging, and the discharging method is more complicated.

[0004] The inventor found that there are at least the following problems in the prior art: the tank structure of the existing suction devices is relatively complicated, various pipelines and dust removal bins need to be arranged, and the sealing performance of the joints of each pipeline needs to be ensured. In addition, the dust removal bin needs to be shut down for cleaning after working for a period of time. Moreover, for the discharging after the tank is full of suction, whether it is a circular tank or a square tank, due to the high center of gravity of the tank, the discharging stability is poor, and the discharging speed cannot be too fast. In such a rescue situation where every second counts, it is necessary to minimize unnecessary downtime as much as possible. The existing suction devices with the tank structure simply cannot approach the rescue site and are not very suitable for the rescue of accidents such as collapses at close range.

[0055] The following will Figures 1 to 5 describe the technical solutions provided by the present invention in more detail.

[0056] Referring to Figure 1 , an embodiment of the present invention provides a tank assembly, including a housing 1, a partition member 2, a dust removal assembly 3 and a cover body 4. The housing 1 includes an inner cavity 10, and the inner cavity 10 is configured to be open; the partition member 2 is installed in the inner cavity 10 to divide the inner cavity 10 into at least independent first chamber 11 and second chamber 12. The partition member 2 includes an air inlet 221. The dust removal assembly 3 is installed in the first chamber 11; the cover body 4 is installed on the housing 1, and the cover body 4 seals the open end of the inner cavity 10; the cover body 4 includes a first suction port 41 communicating with the first chamber 11.

[0057] The housing 1 is welded by splicing square tube profiles and attaching outer plates, and can withstand a certain negative pressure. The housing 1 is the basis of the entire tank assembly, and the housing 1 is generally a cuboid structure. Taking the tank assembly in the suction state as a reference, the top of the housing 1 is open, and the cover body 4 seals the open end. The cover body 4 and the housing 1 are fluid-sealedly connected. After the cover body 4 is covered, the first chamber 11 and the second chamber 12 are each hermetically connected to the cover body 4, and there is no gap between the edge of the first chamber 11 and the cover body 4, that is, the material cannot flow from the gap between the edge of the first chamber 11 and the cover body 4 into the second chamber 12. Similarly, there is no gap between the edge of the second chamber 12 and the cover body 4, and the material cannot flow from the gap between the edge of the second chamber 12 and the cover body 4 into the first chamber 11.

[0058] Continue to refer to Figure 1, in some embodiments, the bottom of the housing 1 is set to be inclined. There are various arrangements: one way is that most of the area of the housing 1 is flat, and one side of the bottom of the housing 1 is inclined. This structure makes it easier for the material to gather at the lower position of the housing 1 after the tank assembly is lifted and inclined as a whole, that is Figure 1 the position shown in A.

[0059] See Figure 1 , the edge of the first bin 11 is higher than the edge of the second bin 12, and the shape of the cover 4 is adapted to the edge contours of the first bin 11 and the second bin 12. Setting the first bin 11 slightly higher than the edge of the second bin 12 can make the volume of the first bin 11 larger and can hold more suction materials.

[0060] The number of the partition members 2 can be only one. In this case, the housing 1 is divided by the partition member 2 into a first bin 11 and a second bin 12. The first bin 11 serves as a material bin for accommodating the adsorbed materials. The second bin 12 serves as a dust removal bin for removing impurities in the gas. Regardless of the number of the first bins 11 and the number of the second bins 12, all the first bins 11 and the second bins 12 share a bottom plate, and the bottom plate is formed by splicing and pasting rectangular tubes.

[0061] In some embodiments, the number of the partition members 2 is two, and the two partition members 2 divide the bin into three parts, one of which is the first bin 11, and the remaining two are the second bins 12. The first bin 11 is located between the two second bins 12. A dust removal device is arranged in each second bin 12. When the tank assembly is in the closed state, at this time the cover 4 is closed, the first bin 11 and the second bin 12 are independent, and they can only be fluidly communicated with each other through the air inlet 221 of the partition member 2.

[0062] See Figure 3 and Figure 4 , in some embodiments, the partition member 2 includes a body 21 and a protrusion 22. The body 21 is configured as a plate; the protrusion 22 is fixed to the top of the body 21. The body 21 is located at the bottom and is a flat plate. The protrusion 22 is located at the top and is convex. The protrusion 22 is formed by bending or welding multiple plates. See Figure 3 and Figure 4 shown. The protrusion 22 includes an air inlet 221 and a plurality of through holes 222. The air inlet 221 and the plurality of through holes 222 are both communicated with the first bin 11.

[0063] In some embodiments, the convex portion 22 protrudes towards the inside of the first bin body 11. The convex portion 22 is generally trapezoidal. There are no holes in the upper part of the convex portion 22. A row of through holes 222 is provided at the middle position of the convex portion 22. The air inlet 221 is located at the bottom of the convex portion 22. The size of each through hole 222 is much smaller than the size of the air inlet 221, and the size of the air inlet 221 is more than 20 times the size of the through hole 222. The through holes 222 are arranged in a row. When the air flow flows from the first bin body 11 to the second bin body 12, due to the large change in the cross-section of the air inlet 221, a lot of eddy currents will be generated at this position when the air flow velocity is relatively fast. By providing the through holes 222, part of the air flow can be shunted, so that part of the gas can enter the second bin body 12 through the through holes 222, which can well reduce the eddy currents and improve the dust removal effect in the second bin body 12.

[0064] The separator 2 adopts a structure with a flat bottom and a trapezoidal top, which maximizes the available volume of the first bin body 11 and ensures the maximum utilization rate of the dust removal bin. The structure of the entire separator 2 does not occupy the external space of the tank assembly. The air inlet 221 with a trapezoidal structure is adopted inside the separator 2, which can make the air flow enter the dust removal components 3 in the two side second bin bodies 12, so that the air flow can make full use of the dust removal components 3.

[0065] The first suction port 41 on the cover body 4 is located at the middle position of the cover body 4 and is in fluid communication with the suction pump described later through the first suction port 41. In order to make the tank assembly applicable to various types of emergency rescue sites, in some embodiments, a second suction port 100 is provided at the top of the side wall of the housing 1. The position of the first suction port 41 is higher than the position of the second suction port 100. The first suction port 41 and the second suction port 100 are arranged in this way, which can maximize the guiding of the material to the top of the first bin body 11, making the available volume of the first bin body 11 larger.

[0066] The dust removal component 3 can adopt an existing structure, and one or more dust removal components 3 can be placed in each second bin body 12. The dust removal component 3 is arranged in each of the two second bin bodies 12. Specifically, the dust removal component 3 can adopt a dust removal filter cartridge device.

[0067] See Figure 2 , in some embodiments, the tank assembly further includes an air outlet duct 5 and an air outlet pipe 6. The air outlet duct 5 is arranged in the inner cavity 10. The air outlet duct 5 is isolated from the first bin body 11 and is in communication with the second bin body 12; the air outlet duct 5 includes a first air outlet 51. The air outlet pipe 6 is located outside the housing 1 and is in fluid communication with the first air outlet 51.

[0068] See Figure 1 and Figure 2, in some embodiments, an opening 13 is provided on the side wall of the housing 1; the tank assembly further includes a side cover assembly 7. The side cover assembly 7 is openably mounted on the opening 13; when the side cover assembly 7 is in the open state, both the first chamber 11 and the second chamber 12 communicate with the outside. When the side cover assembly 7 is in the closed state, the first chamber 11 and the second chamber 12 are closed by the cover body 4 and the side cover assembly 7.

[0069] The first chamber 11 and the second chamber 12 share the same side cover assembly 7. Therefore, when the tank is lifted for discharging, by opening the side cover assembly 7, the materials in the first chamber 11 and the ash layer in the second chamber 12 can be discharged simultaneously, which can ensure the cleanliness of the dust removal chamber to the greatest extent, eliminate the detection of the dust removal chamber, avoid a series of problems caused by untimely ash cleaning in the dust removal chamber, realize one lifting operation and complete two discharging operations, which is simple and convenient, greatly improves the operation efficiency, and is especially suitable for emergency rescue environments.

[0070] See Figure 5 , in some embodiments, the tank assembly further includes a first sealing assembly 8 and a second sealing assembly 9. The first sealing assembly 8 is provided at the edge of the opening 13; the second sealing assembly 9 is provided at the edge of the partition member 2 located in the opening 13. The first sealing assembly 8 and the second sealing assembly 9 form a sealed connection between the first chamber 11, the second chamber 12 and the side cover assembly 7. Both the first sealing assembly 8 and the second sealing assembly 9 can adopt sealing rings.

[0071] The working principle and working environment of the tank assembly determine that the sealing requirement of the tank assembly is very high. In the embodiment of the present invention, the tank assembly is divided into three parts, and the inside of the side cover assembly 7 adopts an independent chamber sealing three-point pressing sealing method, and the second sealing assembly 9 and the partition member 2 are arranged in one-to-one correspondence. The sealing of the second chambers 12 on both sides is realized through two second sealing assemblies 9, and the sealing of the first chamber 11 is realized through the common cooperation of the first sealing assembly 8 and the second sealing assembly 9, ensuring that each chamber does not interfere with each other and does not affect each other; even when sucking materials with a high water content into the first chamber 11, water will not enter the adjacent second cavity, reducing the possibility of damage to the dust removal assembly 3 and ensuring the dust removal effect.

[0072] See Figure 1 , in some embodiments, the bottom surface of the housing 1 is configured to be at least partially inclined; the bottom surface of the housing 1 on the side where the side cover assembly 7 is located is lower than the bottom surface of the housing 1 on the side away from the side surface.

[0073] The bottom of the housing 1 is configured to be an inclined structure, so that the materials in the first chamber 11 and the ash layer in the second cavity gather at the lower part of the housing 1, which is convenient for ash cleaning in the first chamber 11 and also convenient for discharging the materials in the first chamber 11.

[0074] SeeFigure 1 and Figure 5 In some embodiments, the tank body assembly further includes a hook block 14, a hook 15, an oil cylinder 16, a connecting rod 17, and a mounting seat 18. The hook block 14 is fixed to the bottom of the housing 1, and specifically, it can be bolted or welded. The hook 15 is rotatably mounted on the side of the connecting rod 17 away from the oil cylinder 16; the hook 15 switches between a locked state and an unlocked state with the hook block 14. One end of the oil cylinder 16 is mounted on the housing 1, and the oil cylinder 16 is mounted at the bottom of the side cover assembly 7. One end of the connecting rod 17 is connected to the other end of the oil cylinder 16, and a convex block 171 is provided at this end of the connecting rod 17; the other end of the connecting rod 17 is rotatably connected to the hook 15. The mounting seat 18 is fixed to the bottom or lower part of the side cover assembly 7, and the top of the side cover assembly 7 is rotatably connected to the housing 1; the mounting seat 18 includes an oblong hole 181, and the convex block 171 of the connecting rod 17 is located in the oblong hole 181, and the movement track of the convex block 171 is defined by the oblong hole 181.

[0075] The oil cylinder 16 is used to drive the connecting rod 17 to expand and contract. In the locked state, when the oil cylinder 16 is in the extended state, the convex block 171 of the connecting rod 17 is located at the bottom end of the oblong hole 181, the hook block 14 and the hook 15 are hooked together, the side cover assembly 7 and the housing 1 are locked, and the side cover assembly 7 is in the closed state.

[0076] After the suction is completed or the first bin 11 is filled with materials, it is necessary to pour out the materials in the first bin 11, and its operation process is as follows: the oil cylinder 16 retracts, and driven by the oil cylinder 16, the connecting rod 17 and the convex block 171 move along the oblong hole 181 at the same time until the convex block 171 is stuck at the top of the oblong hole 181, that is, the uppermost end of the oblong hole 181. During this process, the hook 15 rotates relative to the hook block 14 so that the engagement between the hook 15 and the buckle is disengaged. After that, the oil cylinder 16 continues to retract. Due to the limiting effect of the convex block 171 and the oblong hole 181, the connecting rod 17 and the convex block 171 no longer move relative to the oblong hole 181, but as the oil cylinder 16 retracts, the entire side cover assembly 7 rotates around its rotatable connection with the housing 1 to realize the opening of the side cover assembly 7. After the side cover assembly 7 is opened, the first bin 11 and each second bin 12 are opened simultaneously. Driven by the lifting mechanism of the suction truck, the entire tank body assembly is tilted, and the materials in the first bin 11 and each second bin 12 are poured out.

[0077] In some embodiments, there are multiple hook blocks 14, and the hook blocks 14 include a plurality of them. The hooks 15 are arranged in one-to-one correspondence with the hook blocks 14; the multiple hook blocks 14 are dispersedly arranged at the bottom of the housing 1. In this way, the side cover assembly 7 and the housing 1 can be locked at multiple positions, and the connection is more stable.

[0078] In some embodiments, the tank assembly further includes a connecting member 19, and each hook 15 is mounted on the connecting member 19. An oil cylinder 16 drives all the hooks 15 to rotate simultaneously to unlock the hooks 15 and the hook blocks 14. The connecting member 19 is an elongated member such as a rod.

[0079] The entire working process is as follows: The sucked material enters the first bin 11 through at least one of the first suction port 41 and the second suction port 100. Under the extrusion of the sucked material, the air inlet 221 and the through hole 222 in the first bin 11 enter the second bins 12 on both sides. The gas is dust-removed by the dust-removing assembly 3 in the second bin 12, and the clean gas after dust removal is extracted by the fan system and discharged into the atmosphere. After the tank is full, the fan system stops working.

[0080] When it is necessary to discharge the material in the first bin 11, the oil cylinder 16 starts to act. First, the hooks 15 and the hook blocks 14 are unlocked, and then the side cover assembly 7 is opened. The locking and unlocking of each hook 15 and hook block 14 are realized through a linkage action of a connecting rod 17, which is more convenient and safe and prevents potential safety hazards caused by misoperation. Finally, the lifting oil cylinder 16 at the bottom of the tank lifts the entire tank assembly to realize the discharging and dust cleaning operations.

[0081] The fluid flow relationship inside the entire tank assembly is as follows: Under the action of the suction pump, the material located outside the tank assembly is sucked into the first bin 11. The original gas in the first bin 11 can only flow into the second bin 12 through the air inlet 221 of the partition member 2. The dust-removing assembly 3 is placed in the second bin 12, and the airflow entering the second bin 12 is dust-removed by the dust-removing assembly 3. The gas after dust removal enters the air outlet duct 5 through the square air outlet on both sides at the rear of the tank, and finally reaches the air outlet pipe 6. The air outlet pipe 6 is connected to the external fan system, so as to extract the gas in the tank, making the inside of the tank in a negative pressure state. In this way, the sucked material falls into the first bin 11, and the gas in the first bin 11 acts through the fan system, passes through a series of air ducts, is dust-removed by the second bins 12 on both sides, and finally discharges the clean gas into the atmosphere to realize the collection of the material.

[0082] The embodiment of the present invention further provides a suction truck, including the tank assembly provided by any technical solution of the present invention.

[0083] In some embodiments, the suction truck further includes a frame (not shown in the figure) and a lifting mechanism (not shown in the figure). The lifting mechanism is installed on the frame and is drivingly connected to the tank assembly to drive the tank assembly to tilt so as to dump the materials in the tank assembly. The lifting mechanism is, for example, an oil cylinder 16. The lifting mechanism is connected to the bottom of the tank assembly. Through the lifting of the lifting mechanism, the tank assembly is tilted as a whole to achieve the dumping of the materials inside the tank. Moreover, the side cover assembly 7 is located on the side of the housing 1. In this way, it is not necessary to open the cover body 4 located at the top of the housing 1, nor to completely invert the tank assembly. Only by tilting at a certain angle can the materials in the first cavity and the second cavity inside the tank assembly be dumped at one time. Further, the bottom of the housing 1 is designed with a slope, which can make the materials in the first bin 11 be driven more easily when the tank structure is lifted for discharging, thereby facilitating the dumping of the tank, reducing the overall lifting and discharging angle of the tank assembly, and making the material dumping more thorough.

[0084] Specifically, the suction truck further includes a suction pump (not shown in the figure). The suction pump is located outside the tank assembly and is in fluid communication with the first suction port 41 and / or the second suction port 100 of the cover body 4 to suck the external materials into the first bin 11. When the first suction port 41 and the second suction port 100 are enabled simultaneously, the adsorption efficiency is higher.

[0085] The above-mentioned suction truck has a simple structure and a small weight. It can quickly suck and transfer the mud, sand and other buried objects covering the rescued object, replacing manual excavation and improving the rescue efficiency. Moreover, the buried objects are directly sucked into the closed first bin without dust, improving the rescue efficiency and the working environment at the same time.
