Definitions

  • the present invention relates to a pump dewatering to draw water from an underground aquifer, pump comprising a tube connecting the surface to the water table to pump, a rod carrying the pistons, connected to a mechanism of training installed on the surface to communicate to the rod a movement back and forth pumping.
  • pump comprising a tube connecting the surface to the water table to pump, a rod carrying the pistons, connected to a mechanism of training installed on the surface to communicate to the rod a movement back and forth pumping.
  • Such pumps are known from, for example, US-A-1,604,734.
  • the present invention aims to remedy some of the disadvantages of the known pumps of dewatering, and proposes to provide a means of training and guidance as simple as possible, little subject to wear even in very difficult operating conditions as in a atmosphere charged with sand or dust, and allowing a very regular and smooth training of the rod of pumping.
  • the symmetrical arrangement of the means of training in a symmetry with respect to the axis of the rod ensures the guiding of the pump rod in the plan of symmetry and maintain the pump head necessarily in this plane of symmetry.
  • the training device is extremely simple and once settled, it can no longer be disrupted, at least for the geometry of the trajectory of the rod.
  • the stroke of the stem is adjusted according to the arm lever the fulcrum of one end of each connecting rod relative to the center of rotation of the gears.
  • Such a pump can be driven by a crank, hand-held, or by an engine, especially an electric motor powered by a solar cell or by a group generator in the case of an electric motor.
  • connection with the drive member is a strap or a chain.
  • Such a machine used as a pump Driven by a motor can also work as an engine fed with fluid under pressure.
  • the invention relates to a dewatering pump comprising a tube 1, provided with a spout exit 2 to discharge the pumped water into an underground aquifer.
  • This dewatering tube 1 receives a rod 3 carrying pistons not shown.
  • Rod 3 makes a movement of and comes (double arrow A) to go down into the water table and goes up, step by step, a certain amount of water that will be poured through spout 2 into a container 4.
  • This rod 3 is driven by a mechanism housed in a housing 5 mounted on a foot 6.
  • the housing 5 houses two identical toothed wheels 7, 8, and rotatably mounted on symmetrical positions with respect to the ZZ direction of the trajectory of the rod 3.
  • the two toothed wheels 7, 8 meshing with each other so as to turn in a direction of opposite rotation.
  • the rotation of the two toothed wheels 7, 8 is ensured by a motor unit consisting either of a crank wheel 9 (FIG 1) or by a motor 10 connected to one of the wheels by a belt 11 (Fig. 2).
  • Two identical rods 12, 13 connect the head of the rod 3, by joints carried by a piece of link 14, at points of articulation carried by the wheels 7, 8. These articulation points 71, 81 occupy symmetrical positions with respect to the ZZ direction of the trajectory of the rod 3 when the wheels 7, 8 are engaged.
  • the rods 12, 13 are driven by the wheels 7, 8, following a symmetrical movement with respect to the direction ZZ. This movement translates into a translation movement back and forth from the stem 3, that is to say a movement pumping.
  • Figure 1 shows the variant of the pump with a crank wheel 9 and Figure 2 the variant with an engine 10 and a belt 11. In both cases, there is a steering wheel inertia 15 to stabilize the rotational movement. This steering wheel does not appear in Figure 1.
  • this is the steering wheel inertia 15 carried by the wheel 7 or by the axis integral with the wheel.
  • the head of the rod 3 is hooked to the two connecting rods 12, 13 which act in tension, the antagonistic effort being the weight rod 3, pistons and pumped water.
  • Figure 3 shows an alternative embodiment in which the toothed wheels 7A, 8A mesh as before and are identical, mounted symmetrically on two axes 72A, 82A symmetrical with respect to the passing ZZ plane by the stem 3A of the dewatering pump whose tube carries the reference 1A.
  • This figure shows the connecting piece 14A to which are articulated heads 121A, 131A connecting rods 12A, 13A and the head 31A of the rod 3A.
  • the rods 12A, 13A do not pull the rod 3A but push it, the wheels 7A, 8A and the connecting rods 12A, 13A being placed below the 14A head carried by the connecting rod 3A.
  • This training is done also by a motor 10A transmitting its movement by a belt or chain 11A passing on a pulley 12A just sketched.
  • the articulation points 71A, 81A of the connecting rods 12A, 13A are adjustable in the radial direction of the wheels 7A, 8A, which makes it possible to modify the length of the induced race in the head 14A and consequently in the rod 3A.
  • the drive mechanism of the stem 3B of the dewatering tube 1B consists of two toothed wheels identical 7B, 8B mounted on symmetrical axes 72B, 82B with respect to the trajectory ZZ of the rod 3B. These two toothed wheels 7B, 8B mesh to rotate in opposite directions.
  • the means of training such as the crank carried by a steering wheel associated with one of the gear wheels or a motor with a transmission chain or belt, are not represented.
  • the mechanism comprises transmission means symmetrical to the rod 3B.
  • the transmission of movement is done by two connecting rods 12B, 13B, articulated in 71B and 81B in symmetrical positions to the gears 7B, 8B.
  • These rods 12B, 13B are connected by an articulation not referenced, each with a lever 14B, 15B mounted around it a respective pivot 16B, 17B.
  • the other end of levers 14B, 15B is articulately connected by a rod 18B, 19B to the rod 3B.
  • rods 18B, 19B are necessary for compensate for the circular motion of the ends of the levers 14B, 15B bearing the joint.
  • the movement back and forth of the rod 3B is shown by a double arrow.
  • the third variant of the invention for the mechanism driving the rod 3C in the dewatering tube 1C, consists of two toothed wheels 7C, 8C, identical and mounted on symmetrical axes 72C, 82C with respect to the plane ZZ moving the rod 3C. These gear wheels, identical mesh to turn in opposite direction. These gear wheels are driven by a means of training such as a crank carried by a steering wheel or motor with a connection by chain belt, not shown.
  • the transmission of the movement towards the rod 3C made by means symmetrical with respect to the plane ZZ.
  • These means consist of a connecting rod 12C, 13C connected to the rod 3C by connecting rods 18C, 19C or by a connecting piece such as parts 14, 14A described above.
  • Connecting rods 12C, 13C are connected to the gears 7C, 8C by levers 14C, 15C whose end is articulated to the corresponding end each connecting rod 12C, 13C and whose other end is connected via a slide 141C, 151C to a pivot 71C, 81C integral with each of the toothed wheels 7C, 8C.
  • Pivots 71C, 81C are carried in fixed positions and symmetrical on the two gears.
  • pivots 71C, 81C constitute relatively sliding rollers in the slides 141C, 151C when the toothed wheels 7C, 8C rotate to induce alternate pivoting motion in the levers 14C, 15C.
  • These levers rotate themselves on pivots 142C, 152C.
  • the up and down movement of the stem 3C is schematized by a double arrow.
  • FIG. 6 a fourth embodiment of the invention will be described below. Common areas with the embodiment of the preceding figures will bear the same references supplemented by the letter D and their detailed description will not be repeated.
  • the piece 14D to which are connected the rods 12D, 13D driven by example via the belt 11D from the 10D motor, is attached to two sets of connecting rods and lever, symmetrical.
  • This transmission assembly connecting the plate 14D to the 3D rod is composed in the left part of the figure, a 30D linkage articulated to the 14D plate and a lever cranked first type with two arms 31D, 34D mounted around a fixed pivot 33D.
