Description

Technical Field

[0001] The utility model relates to the technical field of electric workover rigs, and particularly relates to an extended-range electric power workover rig. Background Art

[0002] A workover rig is a specialized mechanical equipment for repairing downhole strings or wellbores in oil fields, mainly used for operations such as lifting and lowering tubing, sucker rods, and submersible pumps. Current electric workover rigs can be driven by electricity, so there is no need to use a diesel engine as the main power source for the workover rig.

[0003] The utility model patent with the patent authorization announcement number CN 217538617 U discloses a new type of electric workover rig, which includes a workover rig body, a derrick, a drawworks, a power distribution cabinet, and electrical components inside the power distribution cabinet. A mounting plate for installing the power distribution cabinet is fixedly connected to the inner bottom of the workover rig body. A protection mechanism for protecting the power distribution cabinet is provided on the mounting plate. The protection mechanism includes a mounting shell fixedly connected to the upper end of the mounting plate. A rain shield is penetrated through the side wall of the mounting shell, and a threaded rod is rotatably connected to the inner wall of the mounting shell.

[0004] However, there are still some drawbacks when the above device is actually used. The most obvious one is that although the setting of the exhaust fan, the suction hood, and the exhaust pipe can extract the moisture inside the power distribution cabinet at the top of the workover rig body, it will cause the air pressure inside the power distribution cabinet to be lower than the outside. In fact, the outside humid air will enter the power distribution cabinet under the action of negative pressure, which will cause the humidity inside the power distribution cabinet to increase again, and the actual use effect is not ideal.

[0005] Therefore, it is very necessary to invent an extended-range electric power workover rig to solve the above problems. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a range-extended electric power workover rig. By providing an intake drying mechanism, when negative pressure is generated inside the power distribution cabinet due to the discharge of humid air, the negative pressure sucks in external air through the intake pipe. The external air is dried by the desiccant between the two blocking nets and then enters the power distribution cabinet, thereby preventing the humidity inside the power distribution cabinet from rising again. After the desiccant between the two blocking nets can no longer be used, the T-shaped baffle is pulled to the right to release the blockage of the discharge channel. Subsequently, the desiccant between the blocking nets falls and is discharged through the discharge channel. Then, the T-shaped baffle is moved to the left to reset, and then the stop valve is opened. At this time, the desiccant inside the storage hopper falls into the space between the two blocking nets through the feeding pipe, thus completing the filling of the desiccant. Subsequently, the stop valve is closed to solve the problem that although the setting of the exhaust fan, the suction hood, and the exhaust pipe can extract the moisture inside the power distribution cabinet at the top of the workover rig body, it will cause the air pressure inside the power distribution cabinet to be lower than the outside, and in fact, the external humid air will enter the power distribution cabinet under the action of negative pressure, thereby causing the humidity inside the power distribution cabinet to increase again, and the actual use effect is not ideal enough as mentioned in the above background technology.

[0008] A workover rig body, a derrick, a drawworks, and a power distribution cabinet;

[0009] A dehumidification mechanism for dehumidifying the power distribution cabinet; and

[0012] In the range-extended electric power workover rig according to at least one embodiment of the present disclosure, the dehumidification mechanism includes an exhaust pipe and an air pump. The exhaust pipe is fixedly and penetratively arranged on the top of the power distribution cabinet and extends into the power distribution cabinet, the air pump is fixedly arranged on the top of the power distribution cabinet, and the output end of the exhaust pipe is fixedly connected to the input end of the air pump.

[0013] In the range-extended electric power workover rig according to at least one embodiment of the present disclosure, the intake drying mechanism further includes a feeding pipe, a stop valve, a storage hopper, and a sealing cover.

[0014] The extended-range electric power workover rig according to at least one embodiment of the present disclosure, the feeding pipe is fixedly arranged through the top of the air inlet pipe, and the stop valve is arranged on the feeding pipe.

[0016] The technical effects and advantages of the present utility model:

[0017] By providing an air intake drying mechanism in the present utility model, when negative pressure is generated inside the power distribution cabinet due to the discharge of humid air, the negative pressure sucks in external air through the air inlet pipe, and the external air enters the power distribution cabinet after being dried by the desiccant between the two blocking nets, thereby preventing the humidity inside the power distribution cabinet from rising again. When the desiccant between the two blocking nets can no longer be used, the T-shaped baffle is pulled to the right to release the blockage of the discharge channel. Subsequently, the desiccant between the blocking nets falls and is discharged through the discharge channel. Then, the T-shaped baffle is shifted to the left to reset, and then the stop valve is opened. At this time, the desiccant inside the storage hopper falls through the feeding pipe and into the space between the two blocking nets, thereby completing the filling of the desiccant. Subsequently, the stop valve is closed. Compared with the same type of devices in the prior art, the present utility model can effectively discharge the humid air inside the power distribution cabinet, and at the same time can prevent the humidity inside the power distribution cabinet from continuing to rise after dehumidification. In addition, the desiccant can be discharged and added more conveniently, which is more convenient in actual use. Description of the Drawings

[0032] Figure 3 is a schematic diagram of the structure of the intake air drying mechanism 6 of an extended-range electric power workover rig according to an embodiment of the present disclosure.

[0033] Example 1

[0034] As Figures 1-3 shown, the extended-range electric power workover rig of the present disclosure may include components such as a workover rig body 1, a derrick 2, a winch 3, a power distribution cabinet 4, a dehumidification mechanism 5, and an intake air drying mechanism 6.

[0035] As Figure 2As shown, in the present disclosure, the dehumidification mechanism 5 includes an exhaust pipe 51 and an air pump 52. Among them, the exhaust pipe 51 is fixedly and penetratingly arranged on the top of the power distribution cabinet 4 and extends into the power distribution cabinet 4. The air pump 52 is fixedly arranged on the top of the power distribution cabinet 4. The output end of the exhaust pipe 51 is fixedly connected to the input end of the air pump 52.

[0036] Thus, it is convenient to start the air pump 52. The air pump 52 continuously extracts the humid air inside the power distribution cabinet 4 through the exhaust pipe 51, thereby reducing the humidity inside the power distribution cabinet 4 and ensuring the normal operation of the electronic components inside the power distribution cabinet 4.

[0037] As Figure 3 shown, in a preferred embodiment, the intake air drying mechanism 6 includes an intake pipe 61, a discharge channel 62, a T-shaped baffle 63, a blocking net 64, a feeding pipe 65, a stop valve 66, a storage hopper 67 and a sealing cover 68. Among them, the intake pipe 61 is fixedly and penetratingly arranged on the front of the power distribution cabinet 4. The discharge channel 62 is opened at the bottom of the intake pipe 61. The T-shaped baffle 63 slides through the side of the intake pipe 61. There are two blocking nets 64. Both of the two blocking nets 64 are located on the top of the T-shaped baffle 63 and are fixedly connected to the inner wall of the intake pipe 61. A drying chamber is formed between the two blocking nets 64. The drying chamber is filled with a desiccant. The feeding pipe 65 is fixedly and penetratingly arranged on the top of the intake pipe 61. The stop valve 66 is arranged on the feeding pipe 65. The storage hopper 67 is fixedly arranged at the top end of the feeding pipe 65. The storage hopper 67 is filled with a desiccant. The sealing cover 68 is threadedly connected to the top of the storage hopper 67.

[0038] Thus, when a negative pressure is generated inside the power distribution cabinet 4 due to the discharge of humid air, the negative pressure sucks in outside air through the intake pipe 61. The outside air enters the power distribution cabinet 4 after being dried by the desiccant between the two blocking nets 64, thereby preventing the humidity inside the power distribution cabinet 4 from rising again.

[0039] When the desiccant between the two blocking nets 64 can no longer be used, the T-shaped baffle 63 is pulled to the right to release the blockage of the discharge channel 62. Subsequently, the desiccant between the blocking nets 64 falls and is discharged through the discharge channel 62. Then the T-shaped baffle 63 is shifted to the left to reset. Then the stop valve 66 is opened. At this time, the desiccant inside the storage hopper 67 falls through the feeding pipe 65 into the space between the two blocking nets 64, thereby completing the filling of the desiccant. Then the stop valve 66 is closed.

[0040] Embodiment 2

[0041] Different from the above-mentioned Embodiment 1, this device further includes an energy storage device and two generators. One generator is drivingly connected to the engine of the workover rig body 1, and the other generator is drivingly connected to the drive source of the winch 3. So that while the energy storage device can be supplemented by the industrial power supply, the engine of the workover rig body 1 and the drive source of the winch 3 can also charge the energy storage device through the generators, thereby ensuring that the workover rig body 1 can achieve high-power and efficient operation under the condition of a relatively small power capacity source.
