Description

Technical Field

[0001] The utility model relates to the field of lifting submersible pumps for farmland water source wells, in particular to a lifting device for submersible pumps in farmland water source wells. Background Art

[0002] With the advancement of the agricultural modernization process, the modernization level of farmland water conservancy equipment and facilities has been gradually improved, and mechanical equipment has also been widely used in the field of farmland water source wells; during the construction of high-standard farmland construction projects, especially when drilling water source wells in areas with poor hydrogeological conditions and scarce groundwater resources in semi-mountainous areas, it is very difficult to accurately judge the water inflow of the well hole by experience. Only pumping tests can be carried out to determine whether the water inflow of the well hole meets the irrigation requirements of the plot. Therefore, pumps of different specifications and models are frequently lowered into the well hole, gradually lowered to an appropriate position at the bottom of the well, and then lifted up after the pumping test is completed. The pumping test data is used to select the specifications and models of the submersible pump in the well, so as to match the water inflow of the well hole with various parameters such as the drilling depth, the depth of the pump lowered, the head of the submersible pump, the depth of the pump pipe, the flow rate, and the power.

[0003] The installation of submersible pumps (also called lowering the pump, lowering it 15 - 150m below the ground surface in the well hole), maintenance (lifting the submersible pump from 15 - 150m in the underground well hole to the ground and then transporting it to the maintenance point), and maintenance and other operations require certain techniques and a relatively large amount of physical labor; when the submersible pump is at 18 - 150m in the underground well, it used to take 3 - 5 people a long time to pull it out in the past, which was time-consuming, laborious, and costly. With the decreasing rural population year by year, the population engaged in the installation, maintenance, and maintenance of agricultural equipment and facilities is also decreasing year by year. Therefore, a lifting device for submersible pumps in farmland water source wells is needed. Content of the Utility Model

[0004] I. Technical Problems to be Solved

[0005] The technical problem to be solved by the utility model is that during the process of lifting and removing the submersible pump in the wellbore, a large amount of manpower and financial resources are required, and with the decrease of the rural population, this problem has gradually become more acute.

[0006] II. Technical Solution

[0007] To solve the above technical problems, the technical solution provided by the utility model is: a lifting device for submersible pumps in farmland water source wells, including a bottom plate.

[0008] Above the bottom plate, a bracket is connected and provided. At both ends of the bracket, support shafts are rotatably connected. On the support shafts, steel pulleys are connected. On the steel pulleys, wire grooves are connected. Inside the top of the bracket, a lifting rope is connected. The lifting rope is arranged inside the wire groove and is slidably connected with the steel pulley. One end of the lifting rope extends to one end of the bracket and is connected with a hook. On one side below the bottom plate, an electric winch is connected. The other end of the lifting rope away from the hook is wound on the electric winch.

[0009] Furthermore, a channel steel base is connected below the bottom plate to support the hoist device, providing an effective and stable base for it to prevent tipping during use. Its size and the size of the bottom plate can be reasonably set according to the objective needs of the site. Some fixed end structures can also be set below the channel steel base to facilitate installation on relevant loading equipment and facilities, or wheel structures can be installed to facilitate its self-propelled movement. On one side below the bottom plate, a fixing frame cooperating with the electric winch is connected to fixedly install the electric winch on the bottom plate.

[0010] Furthermore, at the position between the two pulleys on the bottom plate, a hydraulic telescopic rod base is connected upward. Above the hydraulic telescopic rod base, a hydraulic rod moving end is connected. The bracket is connected to the hydraulic rod moving end. Between the hydraulic telescopic rod base and the hydraulic rod moving end, a telescopic three-stage oil cylinder is jointly connected. At the bottom of the hydraulic telescopic rod base, an installation plate cooperating with the bottom plate is connected. This hydraulic telescopic mechanism is mainly used for height adjustment of the bracket end. When not in use, it can be lowered to the lowest position, which is also convenient for storage. Among them, this telescopic mechanism realizes multi-stage telescoping through the telescopic three-stage oil cylinder and can have sufficient telescoping space.

[0011] Furthermore, above the electric winch on the bottom plate, a through hole cooperating with the lifting rope is connected. The lifting rope passes through the bottom plate through the through hole.

[0012] Furthermore, at one end of the bracket close to the hook, a limiting rod cooperating with the steel pulley is connected. The limiting rod is located on one side of the steel pulley beside it. The gap between the two only allows the lifting rope to pass through and does not allow the relatively larger hook to pass through. This is to prevent the lifting rope from falling out of the bracket and the pulley group, avoiding relatively troublesome installation during the next use.

[0013] III. Beneficial Effects

[0014] The advantages of the present utility model compared with the prior art are as follows: The device is convenient to use, time-saving and labor-saving, easy to transport, simple and durable in shape. By relying on the lifting rope wound and unwound by the electric winch to replace manual labor to lift and take out the submersible pump underground. On the one hand, it reduces the physical consumption of personnel, and on the other hand, it also reduces the demand for the number of personnel. Through a clever mechanical structure and in cooperation with electric equipment, the submersible pump underground can be taken out with only one or two people. Brief Description of the Drawings

Detailed Description of the Preferred Embodiment

[0020] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Embodiment 1

[0022] Combined with the attached Figures 1-3, To solve the above technical problems, the technical solution provided by the present utility model is as follows: A submersible pump lifting device for farmland water source wells, including a bottom plate 1. A channel steel machine base 2 is connected below the bottom plate 1, which is used to support the lifting device and provide an effective and stable base for it to prevent tipping during use. In order to further make the device more stable during use, some inclined support structure components can also be added to the channel steel machine base 2. Its size and the size of the bottom plate 1 can be reasonably set according to the objective needs on site. Some fixed end structures can also be set below the channel steel machine base 2 to facilitate installation on relevant bearing equipment and facilities, or wheel structures can be installed to facilitate its independent movement and use. The bottom plate 1 is connected upward at a position between two pulleys with a hydraulic telescopic rod base 3. A hydraulic rod mobile end 6 is connected above the hydraulic telescopic rod base 3. A bracket 7 is connected to the hydraulic rod mobile end 6. A telescopic three-stage oil cylinder 5 is jointly connected between the hydraulic telescopic rod base 3 and the hydraulic rod mobile end 6. The bottom of the hydraulic telescopic rod base 3 is connected with a mounting plate 4 that matches the bottom plate 1. This hydraulic telescopic mechanism is mainly used for height adjustment at the bracket 7 end. When not in use, it is lowered to the lowest position, which is also convenient for storage. Among them, this telescopic mechanism realizes multi-stage telescoping through the telescopic three-stage oil cylinder 5 and can have enough telescopic space.

[0023] Through the hydraulic telescopic mechanism with a telescopic three-stage oil cylinder 5, the bracket 7 with a pulley group can be freely adjusted in height in this device. The hydraulic telescopic rod with a telescopic three-stage oil cylinder 5 is also very common on the market. And since the hydraulic telescopic rod components and technologies belong to common and existing technologies, the structural composition and hydraulic operation principle of the hydraulic telescopic mechanism in this application will not be described in detail here. Each stage of the telescopic rod can be regarded as a column. It is recommended that the size of each column be 1.2 - 1.5 meters, and they are combined into a support column structure for supporting the bracket 7. Its total height can reach 4.5 meters. When in use, this support column part must be correspondingly extended so that the bracket 7 has a certain height from the bottom surface. This is convenient for manually removing the submersible pump after it is taken out later. When not working, through its telescopic function, the bracket 7 is lowered to the lowest position, which is convenient for storage and will not make parts such as the bracket 7 in the way.

[0024] Embodiment 2

[0025] Combined with the attached Figures 1-4, a bracket 7 is connected above the bottom plate 1. Support shafts 8 are rotatably connected to both ends of the bracket 7. A steel pulley 9 is connected to the support shafts 8. A wire groove 10 is connected to the steel pulley 9. A lifting rope 12 is connected inside the top of the bracket 7. The lifting rope 12 is arranged to slidably connect with the steel pulley 9 within the wire groove 10. One end of the lifting rope 12 extends to one end of the bracket 7 and is connected with a hook 13. A limiting rod 11 that cooperates with the steel pulley 9 is connected to the end of the bracket 7 near the hook 13. The limiting rod 11 is located on one side of the steel pulley 9 beside it. The gap between the two only allows the lifting rope 12 to pass through, but not the relatively larger-sized hook 13. This is to prevent the lifting rope 12 from falling out of the bracket 7 and the pulley group, avoiding relatively troublesome installation during the next use. On one side below the bottom plate 1, an electric winch 14 is connected. The other end of the lifting rope 12 away from the hook 13 is wound on the electric winch 14. Above the electric winch 14 on the bottom plate 1, a through hole 16 that cooperates with the lifting rope 12 is connected. The lifting rope 12 passes through the bottom plate 1 through the through hole 16. On one side below the bottom plate 1, a fixing frame 15 that cooperates with the electric winch 14 is connected, which is used to fixedly install the electric winch 14 on the bottom plate 1.

[0026] Through the hook 13 at one end of the lifting rope 12, it is connected to the corresponding fixed end on the submersible pump. Submersible pumps are generally designed with components such as hooks 13 and hanging rings. By operating the electric winch 14, the extended lifting rope 12 is wound up. During this process, the submersible pump in the well is pulled out of the bottom surface upwards. After reaching a suitable position above the ground, it is then removed manually or by relevant equipment. Among them, it is recommended that the electric winch 14 adopt a specification of 2.0 kilowatts or 3.5 kilowatts. When this device is installed on a vehicle body for use, the electric winch 14 can use a 12-volt or 24-volt battery or a light gasoline generator configured in an agricultural diesel vehicle as the power source. The length of the lifting rope 12 depends on the depth of the wellbore and should be set to be greater than the wellbore depth. It is recommended that the total length should be greater than 20 meters.

[0027] In the specific implementation of the present utility model, when using this device, place the device near the water source well. As the electric winch 14 operates, the hook 13 at one end of the lifting rope 12 itself has a certain weight. It will gradually move downward as the lifting rope 12 extends. At this time, one can also manually grasp the lifting rope 12 above the hook 13 and slowly pull it downward in an auxiliary manner. The hook 13 enters the bottom of the wellbore and stays above the submersible pump. The hook 13 is hooked onto the lifting ring at the top of the submersible pump. This step can be operated by manually holding the lifting rope 12. The lifting rope 12 is made of soft steel, having a certain weight and toughness. Therefore, there is no need to worry about swaying due to excessive sinking depth. Generally, there will be a lifting ring or a hook 13 structure on the submersible pump. If the submersible pump has a hook-like structure, then just replace the hook 13 on the lifting rope 12 with a lifting ring, which will not have a qualitative impact on the use of this device. When the lifting rope 12 picks up the submersible pump, the electric winch 14 runs in reverse to wind back the released lifting rope 12, and the submersible pump slowly rises, leaving the wellbore and coming above the ground. At this time, one can manually remove it. After use, the lifting mechanism mainly composed of the lifting rope 12 and the bracket 7 can be slowly lowered by the hydraulic telescopic mechanism below to approach the bottom plate 1, so as to be stored, which is convenient for transportation and movement. Through the above operations with this device, the removal of the submersible pump becomes simple, and only one or two people are needed for simple auxiliary and handling work throughout the process.

[0028] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
