Description

Technical Field

[0001] This application relates to pumping test technology, and more particularly to a pumping test apparatus. Background Technology

[0002] During geological exploration, it is necessary to conduct pumping tests on the wells to obtain hydrogeological parameters, evaluate aquifer characteristics, and analyze hydrogeological conditions.

[0003] Currently, a common pumping test setup includes a submersible pump and a weir. The submersible pump is connected to a pumping pipe, which is connected to the inlet of the weir. The weir is used to measure the flow rate. In actual use, due to the weight of the submersible pump, a tripod is usually temporarily erected at the wellhead. A fixed pulley is then installed on the tripod, and the steel cable of an electric winch is routed around the fixed pulley and connected to the submersible pump. The electric winch is then used to lower or raise the submersible pump. Therefore, during the pumping test, not only is a temporary tripod erected, but the various components also need to be assembled on-site, making the entire pumping test process complex and the preliminary preparation work time-consuming and labor-intensive. Utility Model Content

[0004] This application provides a pumping test device to solve the problem that existing pumping test devices not only require temporary tripod erection during use, but also require on-site assembly of various components, resulting in a complicated operation and time-consuming and labor-intensive preliminary preparation work.

[0005] This application provides a pumping test device, including a weir box and a frame. The weir box is installed on the frame, wheels are installed at the bottom of the frame, and a clamping mechanism is installed on the frame. The clamping mechanism clamps and fixes vertically distributed submersible pumps.

[0006] The frame is fixed with an electric winch, an electric hose reel wound with water pipes, and an electric cable reel wound with cables.

[0007] The electric winch's steel rope is fixedly connected to the submersible pump, and the free ends of the water pipe and the cable are both connected to the submersible pump. The rotary joint of the electric hose reel is connected to the weir box through a connecting pipe.

[0008] Optionally, two symmetrically distributed and rotatable guide wheels are provided directly above the submersible pump. The arc surface of the guide wheels is provided with an annular groove I, and the arc surface of the annular groove I is provided with an annular groove II.

[0009] The water pipe passes between the two guide wheels and contacts the wall of the annular groove I. The steel rope of the electric winch passes around the annular groove II of one of the guide wheels, and the cable passes around the other limiting annular groove II.

[0010] Optionally, the clamping mechanism includes two symmetrically distributed clamping plates and two symmetrically distributed lead screws rotatably connected to the frame;

[0011] The lead screw has two threaded structures with opposite directions of rotation. Each lead screw passes through the ends of two clamping plates simultaneously, and one threaded structure is threadedly connected to one clamping plate, while the other threaded structure is threadedly connected to the other clamping plate.

[0012] Optionally, the middle part of the clamping plate has an arc-shaped structure, which is used to clamp the submersible pump.

[0013] Optionally, a suitable rubber pad is fixed to the contact end between the arc-shaped structure and the submersible pump.

[0014] Optionally, the number of clamping mechanisms is two;

[0015] Each lead screw has a sprocket fixed at one end, and all the sprockets simultaneously mesh with a ring chain;

[0016] One of the lead screws is fixed with a handwheel.

[0017] Optionally, the wheels are connected to the lower end of the frame via a shock-absorbing structure;

[0018] The wheels are swivel wheels.

[0019] Optionally, mounting blocks are fixed at all four corners of the frame. Each mounting block has a threaded hole that runs vertically through it. A screw that passes through the threaded hole engages with the threaded hole. A support plate is fixed to the lower end of the screw, and a handle is fixed to the upper end of the screw.

[0020] The pumping test apparatus provided in this application, by setting up a frame, with a weir box mounted on the frame, wheels installed at the bottom of the frame, and a clamping mechanism mounted on the frame, clamps and fixes a vertically distributed submersible pump. An electric winch, an electric hose reel wound with water pipe, and an electric cable reel wound with cable are fixed on the frame. The steel rope of the electric winch is fixedly connected to the submersible pump, and the free ends of the water pipe and cable are both connected to the submersible pump. The rotary joint of the electric hose reel is connected to the weir box through a connecting pipe. This allows for easy lowering or lifting of the submersible pump by simply operating the clamping mechanism, electric winch, electric hose reel, and electric cable reel. Furthermore, since the electric winch, electric hose reel, electric cable reel, and weir box are all mounted on the frame, compared to existing pumping test methods, there is no need to temporarily erect a tripod at the pumping test site, reducing on-site assembly work. This not only makes operation convenient but also shortens preparation time and reduces the labor intensity of workers. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0032] like Figures 1-6 As shown:

[0033] An embodiment of this application provides a pumping test device, including a weir box 1 and a frame 2. The weir box 1 is fixedly installed on the frame 2. Wheels 3 are installed at the bottom of the frame 2. A clamping mechanism 16 is installed on the frame 2. The clamping mechanism 16 clamps and fixes a vertically distributed submersible pump 4 to prevent the submersible pump 4 from shaking and being damaged when the frame 2 is moved.

[0034] The frame 2 is fixed with an electric winch 5, an electric pipe reel 6 with water pipe 61 wound around it, and an electric cable reel 7 with cable 71 wound around it.

[0035] In this system, the steel rope 51 of the electric winch 5 is fixedly connected to the submersible pump 4, and the free ends of the water pipe 61 and the cable 71 are both connected to the submersible pump 4. The rotary joint of the electric hose reel 6 is connected to the weir box 1 via the connecting pipe 8. Specifically, the connecting pipe 8 is a rigid structure, fixedly connected to the frame 2, with one end connected to the rotary joint and the other end connected to the inlet end of the weir box 1.

[0036] In this embodiment, the electric winch 5, electric hose reel 6, electric wire reel 7, and weir box 1 are all existing technologies and will not be described in detail. The electric winch 5, electric hose reel 6, and electric wire reel 7 are connected to control switches, which are mounted on the frame 2 to facilitate the opening and closing of the electric winch 5, electric hose reel 6, and electric wire reel 7.

[0037] In use, move the frame 2 to the drilling well 7 and align the submersible pump 4 with the drilling well 7. Then, operate the clamping mechanism 16 to disengage the submersible pump 4. Next, operate the control switch to release the steel rope 51 from the electric winch 5, the water pipe 61 from the electric hose reel 6, and the cable 71 from the electric cable reel 7. Lower the submersible pump 4 into the drilling well 7 and move it down. After the submersible pump 4 has moved to the desired position, turn off the electric winch 5, the electric hose reel 6, and the electric cable reel 7. Then, start the submersible pump 4 to begin pumping. After pumping is complete, operate the control switch again to reel in the steel rope 51 from the electric winch 5, the water pipe 6 from the electric hose reel 6, and the cable 7 from the electric cable reel 7. Push and pull the submersible pump 4 to move it up. After the submersible pump 4 moves up to the clamping mechanism 16, operate the clamping mechanism 16 to clamp and fix the submersible pump 4.

[0038] The pumping test apparatus provided in this embodiment includes a frame 2, on which a weir box 1 is mounted. Wheels 3 are installed at the bottom of the frame 2. A clamping mechanism 16 is mounted on the frame 2, clamping and fixing a vertically distributed submersible pump 4. An electric winch 5, an electric hose reel 6 wound with a water pipe 61, and an electric cable reel 7 wound with a cable 71 are fixed on the frame 2. The steel rope 51 of the electric winch 5 is fixedly connected to the submersible pump 4. The free ends of the water pipe 61 and the cable 71 are both connected to the submersible pump 4. The rotation of the electric hose reel 6... The connector is connected to the weir box 1 via the connecting pipe 8, so that during use, only the clamping mechanism 16, the electric winch 5, the electric hose reel 6, and the electric wire reel 7 need to be operated to lower or lift the submersible pump 4. Moreover, the electric winch 5, the electric hose reel 6, the electric wire reel 7, and the weir box 1 are all mounted on the frame 2. Therefore, compared with the existing pumping test method, there is no need to temporarily set up a tripod at the pumping test site, and the on-site assembly workload can be reduced. It is not only convenient to operate, but also shortens the preparation time and reduces the labor intensity of the staff.

[0039] In some embodiments of this application, two symmetrically distributed and rotatable guide wheels 9 are provided directly above the submersible pump 4. Specifically, each guide wheel 9 is fixed with a mounting shaft concentric with it. The mounting shaft is rotatably connected to a mounting seat via a bearing, and the mounting seat is fixedly connected to the frame 2. The arc surface of the guide wheel 9 has an annular groove I 91, and the arc surface of the annular groove I 91 has an annular groove II 92. A water pipe 61 passes between the two guide wheels 9 and contacts the groove wall of the annular groove I 91 for guiding the water pipe 61. The steel rope 51 of the electric winch 5 passes around the annular groove II 92 of one of the guide wheels 9 for guiding the steel rope 51. The cable 71 passes around the other limiting annular groove II 92 for guiding the cable 71, allowing the submersible pump 4 to move up and down in a vertical position.

[0040] In this embodiment, the electric reel 6 is located above the two guide wheels 9, the electric winch 5 is located to the side and below one of the guide wheels 9, and the electric reel 7 is located to the side and below the other guide wheel 9.

[0041] In this embodiment, by setting two guide wheels 9, each guide wheel 9 has an annular groove I 91 on its arc surface and an annular groove II 92 on its arc surface, it can not only guide the water pipe 61, steel rope 51 and cable 71 at the same time, but also has a simple structure.

[0042] In some embodiments of this application, the clamping mechanism 16 includes two symmetrically distributed clamping plates 161 and two symmetrically distributed lead screws 162 rotatably connected to the frame 2. Specifically, the ends of the lead screws 162 are rotatably connected to the frame 2 via bearings.

[0043] The lead screw 162 is provided with two threaded structures 163 with opposite directions of rotation. Each lead screw 162 passes through the ends of two clamping plates 161 at the same time, and one of the threaded structures 163 is threadedly connected to one of the clamping plates 161, and the other threaded structure 163 is threadedly connected to the other clamping plate 161.

[0044] In use, rotate both lead screws 162 forward simultaneously, causing the two clamping plates 161 to move towards each other, thus clamping and fixing the submersible pump 4; at the same time, rotate both lead screws 162 in reverse, causing the two clamping plates 161 to move away from each other, thus disengaging the submersible pump 4 from the clamping plates 161, which means releasing the clamping and fixing of the submersible pump 4.

[0045] In some embodiments of this application, the middle part of the clamping plate 161 is an arc-shaped structure, which is used to clamp the submersible pump 4, thereby improving the clamping and fixing effect of the submersible pump 4.

[0046] In some embodiments of this application, a matching rubber pad 164 is fixed to the contact end between the arc-shaped structure and the submersible pump 4 to further improve the clamping and fixing effect of the submersible pump 4.

[0047] In some embodiments of this application, there are two clamping mechanisms 16. Specifically, one clamping mechanism 16 is used to clamp the upper part of the submersible pump 4, and the other clamping mechanism 16 is used to clamp the lower part of the submersible pump 4, thereby further improving the clamping and fixing effect of the submersible pump 4.

[0048] Each lead screw 162 has a sprocket 165 fixed at one end. All sprockets 165 simultaneously mesh with an annular chain 166. After the annular chain 166 meshes with all sprockets 165, the annular chain 166 is in a taut state. One of the lead screws 162 is fixed with a handwheel. Therefore, all lead screws 162 can be rotated simultaneously in the same direction by simply turning the handwheel. In other words, the submersible pump 4 can be clamped and fixed or the clamping and fixing of the submersible pump 4 can be released simply by turning the handwheel.

[0049] In some embodiments of this application, the wheel 3 is connected to the lower end of the frame 2 via a shock-absorbing structure 10 to reduce the vibration generated when the frame 2 moves.

[0050] In this embodiment, the shock absorption structure 10 includes a telescopic tube 101 with closed ends. A buffer spring 102 is provided inside the telescopic tube 101. One end of the buffer spring 102 is fixedly connected to the upper inner end of the telescopic tube 101, and the other end of the buffer spring 102 is connected to the lower inner end of the telescopic tube 101.

[0051] Wheel 3 is a swivel wheel.

[0052] In some embodiments of this application, mounting blocks 11 are fixed at the four corners of the frame 2. The mounting blocks 11 have threaded holes 12 that extend vertically. A screw 13 that passes through the threaded hole 12 engages with the threaded hole 12. A support plate 14 is fixed at the lower end of the screw 13, and a handle 15 is fixed at the upper end of the screw 13.

[0053] In this embodiment, the omnidirectional ball structure is existing technology and will not be described in detail.

[0054] When in use, when the frame 2 is moved to the drilling 7 position, the screw 13 is rotated to bring the support plate 14 into contact with the ground, thereby preventing the frame 2 from moving during the pumping test and affecting the pumping test work.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
