Referring to fig. 1, a first embodiment of the present invention provides a steam drill pumping device, including a steam portion 1 and a pumping portion 2, which are communicated with each other, the steam portion 1 is used for being connected with a steam generating device, the steam portion 1 is used for sending steam into the pumping portion 2, one end of the pumping portion 2, which is far away from the steam portion 1, is provided with a steam jet port 21, the outer surface of the pumping portion 2 is provided with a pumping pipe 3 along the direction of the pumping portion 2, one end of the pumping pipe 3 is in the same direction as the steam jet port, and the other end is connected with an external water pipe (not shown).

The steam drill has the advantages that the water pumping part 2 is combined on the basis of the steam part 1, so that when the steam drill drills a hole, the water pumping pipe 3 can be used for discharging ice-water mixture to the outside of the drilled hole, the water-ice mixture in the ice hole is reduced, the heat utilization rate is improved, and the drilling speed is increased.

Referring to fig. 2, specifically, the steam part 1 includes a first casing 12 and an air drill mechanism 13 disposed inside the first casing 12, the air drill mechanism 13 is configured to accelerate steam to be conveyed to the water pumping part 2, a steam interface 11 is disposed at one end of the first casing 12 away from the water pumping part 2, and the steam interface 11 is configured to be connected to the steam generating device.

It should be noted that the steam generating device can generate steam with a low speed, and the air drill mechanism can accelerate the steam, so that the steam jet port 21 can rapidly jet a large amount of steam to melt the ice surface.

Specifically, the pneumatic drill mechanism 13 includes fan blades 132 and a driving shaft 131, and the fan blades 132 are sequentially disposed on the periphery of the driving shaft 131 along the axial direction of the driving shaft 131.

In this embodiment, the driving shaft 131 is connected to the inner wall of the first housing 12 through a bracket, the bracket is movably connected to two ends of the driving shaft 131, and a motor is further mounted on the bracket and engaged with the driving shaft 131 through a gear for driving the driving shaft 131 to rotate, thereby realizing the rotation of the fan blade 132.

Referring to fig. 2 to 4, in addition, the water pumping part 2 includes a second housing 25, a transmission mechanism 22 and a linkage mechanism 23, the linkage mechanism 23 is disposed near the steam injection port 21, the linkage mechanism 23 includes a connecting rod 232 and a shaft sleeve 231, the connecting rod 232 is provided with a piston 233, a cavity 24 is disposed inside the second housing 25, a sealing cover 34 is disposed above the cavity 24, the cavity 24 is communicated with the middle of the water pumping pipe 3, the piston 233 is in sliding fit with the inner wall of the cavity 24, one end of the transmission mechanism 22 is connected with the driving shaft 131, the other end of the transmission mechanism 22 is provided with an eccentric shaft 221, the shaft sleeve 231 is sleeved on the eccentric shaft 221, and when the transmission mechanism 22 drives the eccentric shaft 221 to rotate, the eccentric shaft 221 drives the connecting rod 232 to reciprocate.

Referring to fig. 5, in the present embodiment, the cavity 24 is a space formed between the piston 233 and the pumping tube 3, and when the connecting rod 232 reciprocates, the piston 233 reciprocates in the cavity 24, so that the size of the cavity 24 can be changed repeatedly, and the cavity 24 is communicated with the middle of the pumping tube 3.

It can be understood that when the space of the cavity 24 is larger along with the movement of the piston 233, the ice-water mixture is sucked in through the opening of the pumping pipe 3, similar to the principle of an injector, whereas when the space of the cavity 24 is smaller, the ice-water mixture in the cavity 24 is discharged, and since the opening of one end of the pumping pipe 3 is in direct contact with the ice-water mixture and the opening of the other end is connected with the external water pipe, the ice-water mixture discharged from the cavity 24 is respectively conveyed to the two openings of the pumping pipe 3, that is, part of the ice-water mixture is discharged out of the drill hole along with the external water pipe. With the repeated movement of the piston 233, the ice-water mixture in the bore hole will continue to be discharged.

It should be noted that the eccentric shaft 221 is a round rod structure, and the cross-sectional area of the sleeve opening of the sleeve 231 is larger than that of the eccentric shaft 221, i.e. the eccentric shaft 221 can move transversely in the sleeve 231. In the present embodiment, the sleeve opening of the sleeve 231 has an oblong structure having a cross-sectional area 2 times that of the eccentric shaft 221, so that the sleeve 231 and the connecting rod 232 can reciprocate up and down without greatly changing or changing the position of the connecting rod 232.

In the present embodiment, the number of the pumping pipes 3 is 2, and in other embodiments, any number may be selected according to actual situations. In this embodiment, two sides of the shaft sleeve 231 are provided with 2 coaxial connecting rods 232, the connecting rods 232 are provided with pistons 233, when the shaft sleeve 231 reciprocates up and down, the 2 pistons 233 also reciprocate, that is, the ice-water mixture can be discharged by using the 2 water pumping pipes 3 without additionally providing a new shaft sleeve 231.

In addition, a planetary reducer 4 is arranged between the driving shaft 131 and the transmission mechanism 22, the driving shaft 131 is connected with an input shaft of the planetary reducer 4, and the transmission mechanism 22 is connected with an output shaft of the planetary reducer 4.

It should be noted that the transmission mechanism 22 is a cylindrical structure, the eccentric shaft 221 is a cylindrical structure which is offset from the axis of the transmission mechanism 22, and since the transmission mechanism 22 is connected with the driving shaft 131, the power source of the eccentric shaft 221 is the driving shaft 131, and no other power source is required to be additionally arranged.

Furthermore, since the main purpose of the driving shaft 131 is to drive the fan blades 132 to accelerate the steam, the fan blades 132 need to rotate faster and better, the eccentric shaft 221 is connected with the piston 233, and the piston 233 needs to be extruded with the inner wall of the cavity 24 to extract the ice-water mixture, so that repeated friction between the piston 233 and the inner wall of the cavity 24 is inevitably needed, and even if the friction between the piston 233 and the inner wall of the cavity 24 is too fast under the condition of water, the piston 233 is damaged quickly, and the planetary reducer 4 is provided in this embodiment, so that the rotating speed of the driving shaft 131 transmitted to the transmission mechanism 22 can be reduced, and the probability of abrasion of the piston 233 can be reduced.

It should be noted that through holes and gaps are reserved between the second casing 25 and the transmission mechanism 22 and between the second casing and the planetary gear 4 for the accelerated steam to pass through.

In addition, a rubber film 234 is arranged on the connecting rod 232, and the middle part and the edge of the rubber film 234 are respectively connected with the connecting rod 232 and the second shell 25 in a sealing manner, so that steam is prevented from losing through the cavity 24.

referring to fig. 6, a first cavity 31 and a second cavity 32 are respectively disposed inside the pumping pipe 3 and located at two sides of the cavity 24, the first cavity 31 is disposed near the steam injection port 21, sealing balls 33 are disposed in the first cavity 31 and the second cavity 32, when the sealing ball 33 in the first cavity 31 moves to a position closest to the steam injection port 21, the sealing ball 33 blocks an opening of the first cavity 31, and when the sealing ball 33 in the second cavity 32 moves to a position closest to the steam injection port 21, the sealing ball 33 blocks an opening of the second cavity 32.

It can be understood that, in fig. 6, when the piston 233 moves downward, negative pressure is generated in the cavity 24, the cavity 24 sucks in ice and water mixture through the opening of the first cavity 31, the sealing ball 33 in the first cavity 31 is located at the leftmost side, and the leftmost side of the first cavity 31 is provided with a plurality of through holes communicated with the cavity 24;

when the piston 233 moves upward, the piston 233 presses the ice-water mixture in the cavity 24 to move towards the first cavity 31 and the second cavity 32, respectively, and at this time, the sealing ball 33 in the first cavity 31 is pressed to the rightmost side of the first cavity 31, and when the sealing ball 33 is pressed and contacted with the rightmost side of the first cavity 31, a seal is formed, and the ice-water mixture in the first cavity 31 cannot be discharged out of the first cavity 31;

the ice-water mixture entering the second cavity 32 pushes the sealing ball 33 to the leftmost side of the second cavity 32, a plurality of notches are formed in the leftmost side of the second cavity 32, the sealing ball 33 cannot be blocked, and the ice-water mixture in the second cavity 32 can be directly discharged;

when the piston 233 moves downward again, negative pressure is generated in the cavity 24, and the ice-water mixture is sucked again, at this time, the sealing ball 33 in the second cavity 32 is driven by the ice-water mixture to move to the rightmost side of the second cavity 32, and the right end opening of the second cavity 32 is sealed, that is, part of the ice-water mixture in the second cavity 32 cannot be sucked into the cavity 24 again, but the ice-water mixture in the first cavity 31 can be directly sucked into the cavity 24, and the ice-water mixture is discharged continuously by reciprocating in this way.

The embodiment greatly reduces the backflow of the ice-water mixture in the first cavity 31 and the second cavity 32, so that the ice-water mixture discharged from the cavity 24 does not return to the drill hole again, and the extraction efficiency of the ice-water mixture is greatly improved compared with that of the first embodiment.
