Detailed Description
The technical solutions in the present application are described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, for a sealing device for treating a forest tree after drilling disclosed in the embodiments of the present application, the sealing device is composed of a main body 11, a flexible guide wire 12, an elastic inner container 13, an elastic outer container 14, an air supply module 16, a liquid supply module 17 and the like, wherein the main body 11 is used for holding by a worker, a first end of the flexible guide wire 12 is a free end, and a second end of the flexible guide wire 12 is fixed on the main body 11, and the first end and the second end are only for convenience of description and do not generate any limitation on the flexible guide wire 12.
The elastic inner container 13 and the elastic outer container 14 are similar in shape, one end is an open end, the other end is a closed end, the open ends of the elastic inner container 13 and the elastic outer container 14 are both fixed on the main body 11, the elastic inner container 13 is located inside the elastic outer container 14, and the flexible guide wire 12 is located inside the elastic inner container 13.
Referring to fig. 2, in some possible implementations, one end of a flexible guide wire 12 is inserted onto the body 11.
Referring to fig. 2, in some possible implementations, an internal thread ring is fixed on the open end of the elastic inner container 13, and correspondingly, an external thread ring is fixed on the main body 11, and the internal thread ring is in threaded connection with the external thread ring, so as to fix the elastic inner container 13 on the main body 11.
Referring to fig. 2, in some possible implementations, an internally threaded ring is also fixed to the open end of the elastic outer container 14, and correspondingly, an externally threaded ring is fixed to the main body 11, and the internally threaded ring is screwed with the externally threaded ring to fix the elastic outer container 14 to the main body 11.
From another perspective, the elastic inner container 13 forms a closed space 131 on the main body 11, and the flexible guide wire 12 is located in the closed space 131. A gap 132 exists between the elastic inner container 13 and the elastic outer container 14, and the function of the gap 132 will be described later.
Referring to fig. 2, through holes 15 are uniformly distributed on the elastic outer container 14, and the through holes 15 are communicated with the slits 132, so that the medium in the slits 132 can flow out, the medium in the slits 132 has two types, the first type is gas, and the second type is liquid medicine (the liquid medicine referred to by the invention can be paste or liquid) for plugging the holes.
The air supply module 16 is installed in the main body 11 and is communicated with the closed space 131 and the gap 132, and is used for providing air with certain pressure for the closed space 131 and the gap 132, the air enters the closed space 131, the elastic inner container 13 can be supported, and the air enters the gap 132, so that the elastic outer container 14 can be supported.
The liquid supply module 17 is also installed on the main body 11 but is only communicated with the gap 132, and is used for injecting the liquid medicine for blocking the hole into the gap 132, and the liquid medicine flowing into the gap 132 flows out of the through hole 15 and is uniformly smeared on the inner wall of the hole.
Referring to fig. 3, the flexible guide wire 12 can be regarded as a guide wire with a certain hardness, can be deformed under the shape of an external force, has a structure similar to a universal nozzle on a machine tool, and is composed of a section of short sections, the connection mode of the section of short section of the rear section and the section of short section of the front section is ball connection, so that a larger movable range is provided between the two sections of adjacent short sections, and meanwhile, the deformed shape can be maintained after the deformation because the connection part is in interference fit.
The function of the flexible guide wire 12 is mainly to enable the elastic inner container 13 and the elastic outer container 14 to extend into the bottom of the hole as far as possible, for example, a worker can adjust the shape of the flexible guide wire 12 according to the shape of the hole, or in the process of inserting the hole, the shape of the flexible guide wire 12 is changed under the action of external force by adopting a mode of shaking up and down and left and right.
In combination with a specific use, the operator holds the main body 11 and then adjusts the flexible guide wire 12 according to the shape of the hole or sways the flexible guide wire 12 up and down and left and right after inserting the flexible guide wire 12 into the hole, so that the flexible guide wire 12 can extend into the bottom of the hole as much as possible.
Then, the air supply module 16 is started to inject compressed air into the closed space 131 formed by the elastic inner container 13 and the main body 11 and the gap 132 between the elastic inner container 13 and the elastic outer container 14, and the volumes of the elastic inner container 13 and the elastic outer container 14 start to increase along with the continuous inflow of air.
Along with the continuous increase of the volumes of the elastic inner container 13 and the elastic outer container 14, the elastic outer container 14 can be attached to the inner wall of the hole, and the shape of the elastic outer container 14 can also be automatically adapted to the shape of the hole, so that a better attaching effect is realized.
It should be understood that if only the gas is injected into the elastic inner container 13 in the above process, when the elastic outer container 14 is attached to the wall of the hole, the outer wall or part of the outer wall of the elastic inner container 13 is also tightly attached to the inner wall of the elastic outer container 14, and then the liquid medicine is injected into the gap 132, so that the situation that the liquid medicine cannot be delivered in part of the region occurs, and therefore, the gas needs to be injected into the gap 132 in advance, so that the gap 132 can always exist.
Then, the liquid supply module 17 is started to inject the liquid medicine for blocking the hole into the gap 132, and the liquid medicine flows out through the through hole 15 and into the hole along with continuous injection of the liquid medicine. It should be understood that the inner wall of the hole is irregular, which means that the elastic outer container 14 cannot be bonded with the inner wall of the hole in a hundred percent, that is, the liquid medicine flowing out of the through hole 15 can enter the space between the elastic outer container 14 and the inner wall of the hole, and the liquid medicine can be uniformly smeared on the inner wall of the hole as the flexible guide wire 12, the elastic inner container 13 and the elastic outer container 14 are pulled by a worker to reciprocate and rotate in the hole.
In the whole, the sealing device for treating the forest tree after drilling provided by the embodiment of the application realizes the self-adaption of the irregular hole shape by virtue of the flexible guide wire 12, and can cover the inner wall of the hole as much as possible; the elastic inner liner 13 and the elastic outer liner 14 are inflated and then expanded to enable the elastic outer liner 14 to be in full contact with the inner wall of the hole; a gap 132 between the elastic inner container 13 and the elastic outer container 14 is used to allow the blocking medical fluid to flow into each portion in the hole.
The plugging mode can enable the liquid medicine to fully soak the inner wall of the hole, so that a better plugging effect is obtained, the liquid medicine can hardly flow out of the hole in the plugging process, and the utilization rate of the liquid medicine is improved.
It will be appreciated that the orientation of the holes in the trunk is uncertain, with some orientations down and some orientations up, and for holes that are oriented down, the injected liquid medicine will flow out very quickly, with very poor sealing effect. When the sealing device for treating the forest tree after drilling is used, the liquid medicine can be fully contacted with the wall of the hole by means of the elastic outer liner 14, the liquid medicine is not wasted, and a better plugging effect can be obtained.
Referring to fig. 2, as a specific embodiment of the sealing device for treating forest tree after drilling provided by the application, a plurality of groups of protrusions 21 are arranged on the outer wall of the elastic inner container 13 and/or on the inner wall of the elastic outer container 14 at intervals, that is, the protrusions 21 are distributed in the following three ways,
first, the protrusion 21 is located on the outer wall of the elastic inner container 13;
second, the protrusions 21 are located on the inner wall of the elastic outer container 14;
third, the protrusions 21 are located on both the outer wall of the elastic inner container 13 and the inner wall of the elastic outer container 14.
In the above three modes, there are gaps between adjacent groups of projections 21, and there are gaps between adjacent projections 21 in the same group.
Referring to fig. 4 (a) and 4 (B), the protrusion 21 always has a gap 132 between the elastic inner container 13 and the elastic outer container 14, so that the outer wall of the elastic inner container 13 may be adhered to the inner wall of the elastic outer container 14 during the inflation process, and the adhesion strength between the adhesion parts may be increased along with the increase of the air pressure.
At this time, the plugging liquid medicine is injected into the slit 132, so that the liquid medicine can only flow into a partial region or even cannot flow into the bottom of the hole, and the protrusion 21 has a certain height, so that the slit 132 can be ensured to exist all the time.
In addition, the hardness of the protrusions 21 is greater than the hardness of the elastic inner container 13 and/or the elastic outer container 14 in order to reduce deformation of the protrusions 21 during the extrusion process. The purpose of the gaps between adjacent sets of projections 21 and between adjacent projections 21 in the same set is also to allow gaps 132 to remain.
In some possible implementations, the protrusions 21 are glued to the outer wall of the elastic inner container 13 and/or to the inner wall of the elastic outer container 14.
Referring to fig. 2, as a specific embodiment of the sealing device for treating a drilled tree, an annular sealing ring 22 is disposed on an outer wall of the elastic outer container 14 at intervals, and an axis of the annular sealing ring 22 and an axis of the elastic outer container 14 are located on the same straight line.
Referring to fig. 5, in use, the annular sealing ring 22 will be in direct contact with the wall of the hole, and at this time, an annular space will be formed on both sides of the annular sealing ring 22, so that the liquid medicine flowing out from the through hole 15 can be temporarily stored in the annular space.
If the staff pulls the flexible guide wire 12, the elastic inner container 13 and the elastic outer container 14 to move or rotate in the hole, the part of liquid medicine can be contacted with the wall of the hole, so that on one hand, the plugging effect can be improved, and on the other hand, the abrasion of the elastic outer container 14 can be reduced to a certain extent.
At the same time, in order to ensure that this annular space can be present, the hardness of the annular sealing ring 22 is greater than that of the elastic bladder 14.
In some possible implementations, the annular sealing ring 22 is bonded to the outer wall of the elastomeric bladder 14.
Further, there is a through hole 15 between any adjacent annular seal rings 22.
Referring to fig. 6, as an embodiment of the sealing device for treating a drilled tree, the air supply module 16 is composed of a chamber 161, a piston 162, a driving device 163, a channel 164, a check valve 165, and the like, specifically, the chamber 161 is located in the main body 11, and the piston 162 is located in the chamber 161 and can slide in the chamber 161.
The piston 162 divides the space in the chamber 161 into two parts, one of which communicates with the enclosed space 131 and the slit 132 through the passage 164, the passage 164 having a first end and two second ends, the first end of the passage 164 communicating with the chamber 161 and the two second ends communicating with the enclosed space 131 and the slit 132, respectively.
The power for the movement of the piston 162 is provided by a driving means 163, the driving means 163 being mounted on the body 11 with its working end projecting into the chamber 161 and being connected to the piston 162, the driving means 163 being capable of being pulled to slide in the chamber 161 when operated.
When the piston 162 slides, the air pressure in the passage 164 changes, specifically, when the piston 162 slides in a direction approaching the passage 164, the air pressure in the passage 164 increases; when piston 162 slides away from passage 164, the air pressure within passage 164 decreases.
In some possible implementations, the drive 163 may use an electric cylinder.
Further, a check valve 165 is added to the portion of the channel 164 communicating with the slit 132, and the check valve 165 functions to prevent the liquid medicine in the slit 132 from flowing back into the channel 164.
Referring to fig. 7, as a specific embodiment of the sealing device for treating a drilled forest tree, the liquid supply module 17 is composed of a liquid storage box 171, a liquid inlet pipe 172, a liquid return pipe 173, a circulating pump 174, and the like, where the liquid storage box 171 is fixed on the main body 11 and is used for storing the liquid medicine needed to be used for sealing the hole.
The first end of the liquid inlet pipe 172 is connected with the liquid storage box 171, the second end is communicated with the gap 132, the first end of the liquid return pipe 173 is connected with the liquid storage box 171, and the second end is communicated with the gap 132 to form a loop. A circulation pump 174 is installed on the liquid inlet pipe 172 or the liquid return pipe 173 for driving the liquid medicine to circulate in the circuit.
The circulation flow has two functions, the first is that the gas in the gap 132 can be discharged by the aid of the continuously flowing liquid medicine, so that the liquid medicine can be distributed more uniformly in the gap 132, and the second is that certain pressure can be provided for the liquid medicine, so that the liquid medicine can better permeate into the hole wall of the hole.
Further, the liquid inlet pipe 172 and the liquid return pipe 173 are connected to the liquid storage box 171 in a plugging manner, which is mainly for reducing the difficulty of disassembly and assembly.
Further, the liquid storage box 171 is detachably fixed to the main body 11, so that the liquid storage box 171 can be replaced immediately, for example, if the liquid medicine is used up during use, and then the liquid inlet pipeline 172 and the liquid return pipeline 173 are inserted into the connecting sockets on the liquid storage box 171.
In some possible implementations, the reservoir 171 is connected to the body 11 by a plug or bolt connection.
The embodiments of the present invention are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in this way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
