Technical Field

[0001] The utility model relates to the technical field of high-pressure diaphragm pumps, in particular to a high-lift and large-flow high-pressure diaphragm pump. Background Art

[0002] The diaphragm pump uses a thin film to separate the pumped liquid from the piston and the pump cylinder, thereby protecting the piston and the pump cylinder. The left side of the diaphragm that contacts the liquid is made of corrosion-resistant materials or coated with a layer of corrosion-resistant substances, and the right side of the diaphragm is filled with water or oil.

[0003] Since the diameter of the water outlet of the diaphragm pump is fixed and the flow rate cannot be adjusted, the head length of the diaphragm pump is short when spraying water, and water spraying for fire extinguishing at a long distance cannot be performed. A Chinese patent (Announcement No.: CN 217950636 U) discloses a portable high-lift forest fire fighting diaphragm pump, which reduces the angle between the blocking block and the horizontal direction by adjusting the inclination angle of the blocking block, thereby reducing the flow rate flowing through the water outlet pipe of the diaphragm pump and increasing the speed of the water flow, thereby increasing the distance of water spraying and increasing the head of the diaphragm pump. However, when adjusting the blocking block in the above document, the staff needs to operate the rotating shaft to rotate while checking the adjusted angle of the blocking block through the water outlet end of the diaphragm pump, which makes it inconvenient to adjust the blocking block.

[0024] Among them, a plurality of sockets are opened at the front end of the support rod 4, and the plug rod 52 is inserted into the inside of the socket, so that the plug rod 52 is inserted into the socket of the support rod 4, so that the push rod 5 can be fixed to the support rod 4, and the staff can know the inclination angle adjusted by the blocking block 3 according to the plug rod 52 is inserted into the socket at different positions.

[0025] Furthermore, a through hole is formed at the front end of the vertical block 51 , and the insertion rod 52 is slidably connected to the inner side of the through hole, so that the insertion rod 52 can be moved out of or into the vertical block 51 through the through hole.

[0026] In addition, both left and right walls inside the vertical block 51 are provided with sliding grooves, and the support blocks 54 are located inside the sliding grooves and are slidably connected thereto, so that the connecting block 53 can be suspended in the inner cavity of the vertical block 51 through the two support blocks 54 and move forward and backward.

[0027] See also Figure 3The pulling structure in this embodiment includes a pull rope 55 fixed to the front end of the connecting block 53, and the pulling structure also includes a transverse roller 56 rotatably connected to the left and right walls of the inner cavity of the vertical block 51 through bearings, so that the lower end of the inner side of the pull rope 55 abuts against the top of the transverse roller 56, so that the pull rope 55 can form an L shape through the transverse roller 56, and a pressure block 57 is fixed to the outside of the pull rope 55, and a transverse block 58 is slidably connected to the outside of the pull rope 55. Two first springs 59 are fixed to the side opposite to the pressure block 57 and the transverse block 58, and a rotating rod 510 is fixed to the other end of the pull rope 55. The pulling structure also includes a second spring 511 fixed to the front end of the connecting block 53, and the other end of the second spring 511 is fixed to the front wall of the inner cavity of the vertical block 51.

[0028] Secondly, a circular hole is opened at the front end of the vertical block 51, and the rotating rod 510 is rotatably connected to the inside of the circular hole, so that the rotating rod 510 can pass through the outside of the vertical block 51, which is convenient for the staff to rotate the rotating rod 510. The rear end of the rotating rod 510 is rotatably connected to the rear wall of the inner cavity of the vertical block 51 through a bearing, so that the rotating rod 510 can be firmly located inside the vertical block 51 for rotation.

[0029] In addition, the horizontal block 58 is fixed to the front wall of the inner cavity of the vertical block 51 , and a through hole is opened at the top of the horizontal block 58 . The pull rope 55 passes through the through hole and is slidably connected thereto, so that the pull rope 55 can slide inside the horizontal block 58 .

[0030] Moreover, a round hole is formed at the top of the pressing block 57 , and the pull rope 55 passes through the inside of the round hole and is fixed thereto, so that the pressing block 57 can be fixed to the outside of the pull rope 55 .

[0031] The working principle of the above embodiment is:

[0032] When in use, when it is necessary to adjust the inclination angle of the blocking block 3, the staff rotates the rotating rod 510 to make the rotating rod 510 reel in the pull rope 55, so that the length of the top of the pull rope 55 is gradually shortened, so that the pull rope 55 can pull the connecting block 53 to move forward in the inner cavity of the vertical block 51, and the connecting block 53 squeezes the second spring 511, so that the connecting block 53 can drive the insertion rod 52 to move out of the insertion hole of the support rod 4 and move to the inside of the push rod 5. When the pull rope 55 pulls the connecting block 53 to move, the pull rope 55 can drive the pressing block 57 to move downward, so that the pressing block 57 and the horizontal block The spacing between the two first springs 59 is gradually shortened, so that the pressing block 57 and the cross block 58 can squeeze the two first springs 59, that is, the push rod 5 can be moved into the water outlet end 2 of the diaphragm pump body 1, so that the push rod 5 can push the blocking block 3 to tilt at an angle, so that the staff can know the tilt angle of the blocking block 3 pushed by the push rod 5 through the corresponding insertion hole position of the insertion rod 52 and the support rod 4, so that the staff does not need to operate the rotating shaft while checking the adjusted angle of the blocking block 3 through the water outlet end 2 of the diaphragm pump, which can effectively improve the convenience of adjusting the blocking block 3;

[0033] After the adjustment is completed, the rotating rod 510 is loosened, and the two first springs 59 can push the pressure block 57 to move upward. While the pressure block 57 moves upward, the pressure block 57 can pull the pull rope 55, so that the pull rope 55 can pull the rotating rod 510 to rotate in the opposite direction, so that the pull rope 55 is no longer entangled outside it. At the same time, the length of the top end of the pull rope 55 is gradually extended, and the second spring 511 can push the insertion rod 52 to move to the corresponding insertion hole through the connecting block 53, so as to complete the adjustment of the blocking block 3, which has the effect of increasing the flow rate, thereby increasing the distance of water spraying and increasing the lift of the diaphragm pump body 1.
