[0026] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0027] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0028] Reference Figure 2 This embodiment provides a connecting mechanism that facilitates the connection of the water pump to the support frame.

[0029] The connecting mechanism includes a fixing component 201 and a connecting component 202 that is detachably connected to the fixing component 201.

[0030] The fixing component 201 has a stop 201b, and the connecting component 202 includes a snap-fit ​​assembly 202b. The snap-fit ​​assembly 202b is adapted to extend into the fixing component 201 and be fixedly connected with the stop 201b after the connecting component 202 is mated with the fixing component 201.

[0031] As an optional embodiment, refer to Figure 2 The fixing component 201 includes a fixing body 201c, which is a shell. The top of the fixing body 201c is welded to the top plate 101. The bottom wall of the fixing body 201c is provided with a receiving opening 201a. The inner diameter of the receiving opening 201a is smaller than the inner diameter of the fixing body 201c. Due to the difference in size between the receiving opening 201a and the inner cavity of the fixing body 201c, a stop 201b is formed circumferentially in the receiving opening 201a. The stop 201b is specifically a hanging platform formed circumferentially along the receiving opening 201a.

[0032] The bottom wall of the fixed body 201c is detachably connected to the connecting body 202a. The connecting body 202a is a shell. The top opening of the connecting body 202a is connected to the bottom wall of the fixed body 201c. The bottom of the connecting body 202a is provided with a through hole 202c.

[0033] A snap-fit ​​component 202b is provided inside the connecting body 202a. The snap-fit ​​component 202b passes through the connecting body 202a and extends into the fixing body 201c along the receiving opening 201a, forming a fixed connection with the fixing body 201c.

[0034] Specifically, refer to Figure 2 , 34. The snap-fit ​​assembly 202b includes a second hinge plate 202b-5. The second hinge plates 202b-5 are symmetrically arranged and are bolted or welded to both sides of the top opening of the connecting body 202a. The opposite ends of the second hinge plates 202b-5 are respectively provided with first mounting grooves 202b-7, and pins are fixedly installed in the first mounting grooves 202b-7.

[0035] The snap-fit ​​assembly 202b also includes symmetrically arranged snap-fit ​​members 202b-3, see reference. Figure 4 The fastener 202b-3 is designed in the shape of a long plate, and a guide groove 202b-6 is provided in the middle of the fastener 202b-3.

[0036] The guide groove 202b-6 includes a first segment 202b-6a and a second segment 202b-6b. The first segment 202b-6a is parallel to the axial direction of the fastener 202b-3, and the second segment 202b-6b is set at an obtuse angle to the first segment 202b-6a. Specifically, the end of the second segment 202b-6b away from the first segment 202b-6a is offset toward the stop 201b, so that the second segment 202b-6b of the symmetrical fastener 202b-3 is V-shaped. The fastener 202b-3 is installed in the first mounting groove 202b-7. The pin of the first mounting groove 202b-7 passes through the guide groove 202b-6, and the guide groove 202b-6 can slide relative to the pin of the first mounting groove 202b-7. The first mounting groove 202b-7 is sized similarly to the fastener 202b-3 to ensure the stability of the sliding of the fastener 202b-3.

[0037] When the pin of the first mounting groove 202b-7 engages with the first section 202b-6a, the fastener 202b-3 is in the engaging position, and the hook 202b-4 on the top of the fastener 202b-3 hooks onto the stop 201b; when the pin of the first mounting groove 202b-7 engages with the second section 202b-6b, the hook 202b-4 is relatively close together, the fastener 202b-3 is in the disengaged position, the hook 202b-4 is disengaged from the stop 201b, and can exit the cavity of the fixed body 201c along the receiving opening 201a.

[0038] Reference Figure 2 Alternatively, in the connecting body 202a, a first hinge plate 202b-1 is also installed. The first hinge plate 202b-1 has a second mounting groove 202b-8 at each end. A pin is installed in the second mounting groove 202b-8. The bottom of the fastener 202b-3 is hinged to the pin of the second mounting groove 202b-8. The second mounting groove 202b-8 and the fastener 202b-3 are of similar size to ensure the stability of the sliding of the fastener 202b-3.

[0039] Reference Figure 2Alternatively, the snap-fit ​​assembly 202b may also include a connecting post 202b-2, which is made of a metal column. The top of the connecting post 202b-2 passes sequentially from the bottom of the connecting body 202a through the through hole 202c and the connecting hole 202b-9 opened in the middle of the first hinge plate 202b-1, and is fixedly connected to the first hinge plate 202b-1. Specifically, the top of the connecting post 202b-2 is provided with a threaded section, the outer diameter of which is smaller than that of the non-threaded section. The threaded section passes through the first hinge plate 202b-1, and then the nut is tightened to fix the first hinge plate 202b-1 to the top of the connecting post 202b-2.

[0040] When assembling the fixing component 201 and the connecting component 202, refer to Figure 2 : First, complete the preparation work for the snap-fit ​​assembly 202b, push up the connecting post 202b-2, and the snap-fit ​​part 202b-3 moves upward relative to the second hinge plate 202b-5 until the second segment 202b-6b engages with the pin of the first mounting groove 202b-7; due to the setting angle of the second segment 202b-6b and the hinged connection between the bottom of the snap-fit ​​part 202b-3 and the first hinge plate 202b-1, the hook head 202b-4 set on the top of the snap-fit ​​part 202b-3 is relatively gathered together, and the maximum outer diameter of the hook head 202b-4 after being relatively gathered together is smaller than the inner diameter of the receiving opening 201a; Second, after the hooks 202b-4 are brought together, the top opening of the connecting body 202a is aligned with the receiving opening 201a of the fixed body 201c. The connecting column 202b-2 is pulled down, and the buckle 202b-3 moves down relative to the second hinge plate 202b-5 until the top of the first section 202b-6a engages with the pin of the first mounting groove 202b-7. The hooks 202b-4 are separated and hooked on the stop 201b, thus completing the fixed connection of the connecting mechanism 200.

[0041] It should be noted that, to facilitate the alignment of the fixing body 201c and the connecting body 202a, a groove is coaxially formed on the top of the connecting body 202a. The groove is set with the same outer diameter as the fixing body 201c. After the fixing body 201c is placed in the groove on the top of the connecting body 202a, the fixing body 201c and the first connecting body 202a are aligned. In this embodiment, the snap-fit ​​component 202b is set in two sets. It can be understood that, in order to improve the snap-fit ​​strength, several sets of snap-fit ​​components 202b can be set, evenly distributed on the connecting body 202a.

[0042] As another alternative embodiment of the snap-fit ​​assembly, refer to Figure 5 The snap-fit ​​assembly 202b includes snap-fit ​​members 202b-3 arranged opposite to each other. Each snap-fit ​​member 202b-3 has a hook head 202b-4 on its top, which is used to fix it to the stop member 201b.

[0043] One of the fasteners 202b-3 extends from the bottom of the fastener 202b-3 on one side toward the fastener 202b-3 on the other side, and a plug-in plate 202b-11 is provided at the corresponding position of the fastener 202b-3 and the plug-in plate 202b-11 on the other side. The plug-in plate 202b-11 and the plug-in plate 202b-10 are compatible.

[0044] Specifically, as the positions of the two side fasteners 202b-3 change, the plug plate 202b-11 inserts into the plug interface 202b-10 or slides out of the plug interface 202b-10 to maintain the relative position of the two side fasteners 202b-3 in the length direction.

[0045] The connecting mechanism 200 also includes a connecting body 202a, which has a first oblique insertion hole 202b-13 and a second oblique insertion hole 202b-14. The first oblique insertion hole 202b-13 and the second oblique insertion hole 202b-14 are arranged in a V-shape, and a receiving cavity 202b-15 is provided at the bottom connection. The plug plate 202b-11 and the plug interface 202b-10 are slidably connected in the receiving cavity 202b-15.

[0046] The first oblique insertion hole 202b-13 and the second oblique insertion hole 202b-14 are respectively adapted to the buckle pieces 202b-3 on both sides.

[0047] Specifically, the first oblique insertion hole 202b-13 is sized similarly to the buckle 202b-3 on one side, and the second oblique insertion hole 202b-14 is sized similarly to the buckle 202b-3 on the other side. When the buckle 202b-3 moves outward along the first oblique insertion hole 202b-13 and the second oblique insertion hole 202b-14, the hook 202b-4 at the front end of the buckle 202b-3 separates from each other through the guiding action of the first oblique insertion hole 202b-13 and the second oblique insertion hole 202b-14, so that it can be hooked onto the stop 201b. When the fastener 202b-3 moves toward the inside of the connecting body 202a along the first oblique insertion hole 202b-13 and the second oblique insertion hole 202b-14 respectively, the hook head 202b-4 at the front end of the fastener 202b-3 moves closer to each other through the guiding effect of the first oblique insertion hole 202b-13 and the second oblique insertion hole 202b-14, so that the hook head 202b-4 separates from the stop member 201b.

[0048] Furthermore, the bottom of the connecting body 202a has a through hole 202c, which penetrates and connects to the receiving cavity 202b-15. The through hole 202c is a threaded hole, and a screw 202b-12 is screwed into the through hole 202c. The screw 202b-12 extends into the receiving cavity 202b-15 through the through hole 202c. The top of the screw 202b-12 is rotatably connected to a snap fastener 202b-3 on one side.

[0049] When screw 202b-12 is screwed into the receiving cavity 202b-15, screw 202b-12 pushes the latching parts 202b-3 on both sides to move outward of the connecting body 202a, so that the latching parts 202b-3 on both sides are fixed with the stop part 201b, that is, the connecting part 202 is fixed with the fixing part 201.

[0050] When screw 202b-12 is turned outward into the receiving cavity 202b-15, screw 202b-12 drives the latching parts 202b-3 on both sides to move inward into the connecting body 202a, so that the latching parts 202b-3 on both sides disengage from the stop part 201b, that is, the fixed connection between the connecting part 202 and the fixing part 201 is released.

[0051] Reference Figure 1 This embodiment also provides a portable water pump lifting device, which is used to lower the water pump to the bottom of the well or lift it out from the bottom of the well.

[0052] This device includes a support frame 100, specifically including a top plate 101 and a support leg 102. The bottom end of the support leg 102 is supported on the ground at the wellhead, and the top end of the support leg 102 is fixedly connected to the top plate 101, serving as the support mechanism for this device.

[0053] The bottom surface of the top plate 101 is detachably connected to a connecting mechanism 200, and the other end of the connecting mechanism 200 is fixedly connected to the pulley component 300.

[0054] The pulley assembly 300 includes a fixed pulley assembly 301, which is used to lift or lower the water pump.

[0055] Specifically, the fixed pulley assembly 301 includes a fixed pulley connecting cover 301b, the top of which is fixedly connected to the connecting column 202b-2, and a fixed pulley 301a is hinged inside the fixed pulley connecting cover 301b.

[0056] Furthermore, the pulley component 300 also includes a movable pulley assembly 302, on which a water pump is suspended. The movable pulley assembly 302 includes a movable pulley 302a, and a movable pulley connecting cover 302b is hinged to the outside of the movable pulley 302a. The movable pulley connecting cover 302b is arranged downwards, and a hook 302d is fixedly installed on its bottom surface.

[0057] The movable pulley assembly 302 also includes a lifting ring 302c, which is bolted to the bottom surface of the top plate 101. A rope 303 is attached to the lifting ring 302c, and the other end of the rope 303 passes through the bottom of the movable pulley 302a and then overlaps the fixed pulley 301a, so that the pulley assembly 300 forms a force-saving pulley group.

[0058] When it is necessary to hoist a water pump, tie the other end of rope 303 to a power traction device or pull it manually.

[0059] When using this device, first erect the support frame 100 above the wellhead, install the lifting ring 302c and connecting component 202, then fix the fixed pulley assembly 301 to the connecting column 202b-2, tie one end of the rope 303 to the lifting ring 302c, pass the other end through the bottom of the movable pulley 302a, and then overlap the fixed pulley 301a. Fix the water pump on the hook 302d, and gradually lower the rope 303 to put the water pump into the well; after pumping is completed, pull the rope 303 to gradually pull the water pump out. After use, the rope 303, fixed pulley assembly 301, movable pulley assembly 302, connecting part 202 and lifting ring 302c are removed in sequence and placed in the storage container for easy handling and carrying.

[0060] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
