Description

Technical Field

[0001] The utility model relates to the field of water conservancy irrigation equipment, in particular to a hoisting bracket for an underground water pump for agricultural irrigation. Background Art

[0002] Agricultural irrigation can generally be divided into surface irrigation, ordinary sprinkler irrigation and micro-irrigation. Due to its good water-saving performance and high water utilization rate, micro-irrigation is widely used in the irrigation of gardens and lawns within cities. A sprinkler pump is an important device in agricultural irrigation. However, in some remote low-lying areas or underdeveloped areas, most sprinkler pumps need to be sent into the well for pumping water, and the water pump is fixed by hoisting it with a pump bracket. The existing pump bracket is generally in the form of a three-legged scaffold. A rotating wire roller is provided on the three-legged scaffold, and the water pump is hoisted by a hoisting wire on the rotating wire roller. However, the defect of this structure is that when the water pump is lowered through the rotating roller, the water pump will rotate, thus driving the connected cables and water pipes to twist. However, we know that the water pipes and cables are not allowed to twist when being lowered into the well with the water pump. Once twisted, the water pipe will have a large resistance to water and impact the water pipe, and in severe cases, the water pipe will burst. The twisted cable is likely to cause the cable to break. Therefore, it is necessary to design a new bracket to avoid the above situation. Content of the Utility Model

[0003] When the existing water pump hoisting bracket lowers the water pump, the water pump will rotate, and at the same time, it will drive the connected water pipes and cables to rotate, resulting in the twisting of the water pipes and cables. Once twisted, the water pipe will have a large resistance to water and impact the water pipe, and in severe cases, the water pipe will burst. The twisted cable is likely to cause the cable to break. At least one object or aspect of this application can solve the above problems. Specifically, a hoisting bracket for an underground water pump for agricultural irrigation is designed, and the technical solution adopted is as follows:

[0029] To clearly illustrate the technical features of this solution, the present utility model will be elaborated in detail below through specific embodiments in conjunction with the accompanying drawings.

[0030] In addition, in the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0031] As Figure 1 shown, a hoisting bracket for an underground water pump used in agricultural irrigation includes a first frame body 1, a second frame body 2, a wire roller 5, the lifting rope 7 thereon, and a guiding component 10. The upper ends of the first frame body 1 and the second frame body 2 are hinged to each other, and the lower ends of the first frame body 1 and the second frame body 2 are fixed ends. The so-called fixed end means that the lower ends of the first frame body 1 and the second frame body 2 are fixed on the ground.

[0032] The lifting rope 7 is wound around the wire roller 5, and the central rotating shaft of the wire roller 5 is rotatably arranged at the hinge connection of the first frame body 1 and the second frame body 2, that is, the central rotating shaft of the wire roller 5 is horizontally arranged front and back. In actual use, the first frame body 1 and the second frame body 2 are located on both sides of the water well, the wire roller 5 is located directly above the water well, the lifting rope 7 thereon is connected to the water pump, one end of the central rotating shaft of the wire roller 5 is connected to the transmission gear 6, and then the rotating shaft of the gear can be connected with a handle. By manually rotating the handle to drive the wire roller 5 to rotate and lower the lifting rope 7, the water pump is sent into the well for pumping water.

[0033] The guiding component 10 is to ensure that the water pump does not rotate when it is lowered into the well. The guiding component 10 is connected to the position near the tail end of the lifting rope 7. Here, the tail end refers to the position near the connection of the lifting rope 7 to the water pump. It can abut against the well wall. When the lifting rope 7 lowers the water pump, the guiding component 10 can descend along the well wall while abutting against the well wall. Abutting against the well wall restricts the rotation of the lifting rope 7 and avoids the twisting of the cables and water pipes connected to the water pump.

[0034] Furthermore, the structure of the guiding component 10 specifically includes a connecting head 1002, a first support rod 1001, a second support rod 1003, and an elastic member 1005. The connecting head 1002 is connected to the lifting rope 7. Here, the connecting head 1002 and the lifting rope 7 can be connected by means such as crimping and bonding. The first support rod 1001 and the second support rod 1003 are symmetrically located on both sides of the connecting head 1002. Among them, the upper end of the first support rod 1001 is hinged to the connecting head 1002, and a first guiding wheel 1006 is rotatably connected to the lower end. The upper end of the second support rod 1003 is hinged to the connecting head 1002, and a second guiding wheel 1004 is rotatably connected to the lower end. The elastic member 1005 is connected between the middle parts of the first support rod 1001 and the second support rod 1003 near the middle parts of the two. In the initial state, the elastic member 1005 is in its original length state. The distance between the first guiding wheel 1006 at the bottom end of the first support rod 1001 and the second guiding wheel 1004 at the bottom end of the second support rod 1003 in its original length state is greater than the diameter of an ordinary water well. Therefore, when the guiding component 10 is lowered into the water well, the elastic member 1005 will be compressed. The elastic force of the elastic member 1005 abuts the first guiding wheel 1006 and the second guiding wheel 1004 against the well wall, so that the water pump and the cables and water pipes thereon will not twist.

[0035] Furthermore, the above-mentioned elastic member 1005 is a spring or a rubber column. The rubber column thickens or bends when compressed, and the spring shortens when compressed. Whichever of the two is used can generate elastic potential energy to promote the abutment of the first guiding wheel 1006 and the second guiding wheel 1004 against the well wall.

[0036] Furthermore, due to the humid underground environment, in order to improve the anti-corrosion effect of the guiding component 10, the above-mentioned first support rod 1001 and second support rod 1003 are set as aluminum rods.

[0037] Furthermore, the structures of the above-mentioned first frame body 1 and second frame body 2 are the same, and both include a first connecting rod 101, a second connecting rod 102 and a bottom plate 103. The first connecting rod and the second connecting rod 102 are arranged in parallel at intervals front and back. The bottom plate 103 is horizontally connected between the bottom ends of the first connecting rod 101 and the second connecting rod 102, and forms a quadrilateral arrangement with the central rotating shaft of the wire roller 5. The above-mentioned first connecting rod 101 and second connecting rod 102 can be straight rods or curved rods (arc-shaped rods). In short, the overall shape is a quadrilateral frame structure. The purpose of such a setting is to help with leveling. Especially on uneven ground, the two quadrilateral frames will form four fulcrums at the edges, and the height of the four fulcrums can be adjusted to level the bracket.

[0038] Furthermore, a number of lifting supports 3 are provided on each of the above-mentioned bottom plates 103. In this application, two lifting supports 3 are provided. Each lifting support 3 includes a screw rod 302, and one end of the screw rod 302 is threadedly passed through the bottom plate 103 and rotatably connected to the base 301 through a bearing.

[0039] Furthermore, the existing water pump bracket does not have a special position for fixing the cable. In order to improve the orderly effect of the bracket in this application, a cable clip 4 is also provided on the first frame body 1 or the second frame body 2. When the cable is lowered to a certain height underground along with the water pump, it is clamped on the cable clip 4 to fix the cable and prevent the cable from sliding down the well.

[0040] Furthermore, the existing water pump bracket does not have a component for buffering and leading out the water pipe from the wellhead. Instead, a temporary support is placed under the water pipe to avoid excessive bending angle of the water pipe, but this temporary support is not easy to operate and is prone to falling off after a long time. Therefore, in order to solve the above problems, a guide plate 8 is also connected to the first frame body 1 or the second frame body 2 through a bolt 9. The rotation central axis of the guide plate 8 is parallel to the central rotating shaft of the wire roller 5, that is, the guide plate 8 is arranged front and back. Here, the bolt 9 connection can change the angle of the guide plate 8. When the angle of the guide plate 8 needs to be changed, loosen the bolt 9, rotate the guide plate 8 to the required angle, and then tighten the bolt 9 to fix it.

[0041] Furthermore, in order to lead out the water pipe from the wellhead more smoothly, the above-mentioned guide plate 8 is an arc-shaped plate, and the center of curvature of the arc-shaped plate is located on one side of the lower end of the first frame body 1 or the second frame body 2.

[0042] The above specific embodiments cannot be used to limit the protection scope of the present invention. For those skilled in the art of this technology, any alternative improvement or transformation made to the embodiments of the present invention falls within the protection scope of the present invention.

[0043] Where the present invention is not described in detail, it is all well-known technology to those skilled in the art of this technology.
