DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] See also Figure 1 and Figure 2The invention discloses a device for inspecting and repairing a well joint and a coarse filter, comprising an oil collecting basin 1, wherein the bottom surface of the oil collecting basin 1 has a plurality of inclined surfaces, and the plurality of inclined surfaces are inclined toward the same low point. An oil collecting groove 101 is provided at the lowest point of the oil collecting basin 1, and a filter cartridge 102 is detachably connected to the oil collecting groove 101. A bracket 103 is fixedly connected to the top of one side of the oil collecting basin 1, and a pneumatic oil pump 2 is detachably connected to the bracket 103 through two half-moon fasteners. The pneumatic oil pump 2 can rotate 360 degrees on the bracket 103, and the oil inlet of the pneumatic oil pump 2 extends downward. To the bottom of the oil collecting tank 101, the oil outlet of the pneumatic oil pump 2 is connected to the spray gun 3 through an infusion pipe. The ground well joint and the coarse filter are flushed by the spray gun 3, which can replace the original brush cleaning, improve the cleaning speed, and save labor time. A hose fixing frame 4 for fixing the ground well hose is provided at the bottom of the oil collecting basin 1. A splash shield 5 is placed in the oil collecting basin 1. The splash shield 5 can play a protective role when flushing the ground well joint and the coarse filter to prevent oil from splashing everywhere, polluting the environment and accidentally injuring workers.
[0020] See also Figure 1 and Figure 4 The hose fixing frame 4 is composed of three arc-shaped plates, one of which is hinged to the other two arc-shaped plates, and the non-hinged ends of the other two arc-shaped plates are connected by a lock. Specifically, the lock includes a screw, a hook and a bent piece. The screw is hinged to the hook. The screw is threadedly connected to the non-hinged end of one arc-shaped plate, and the bent piece is fixed to the non-hinged end of the other arc-shaped plate. The hook and the bent piece cooperate to clamp the ground well rubber. The tightening degree of the hose fixing frame 4 on the ground well hose is controlled by rotating the screw. The hose fixing frame 4 is installed at the bottom of the oil collecting basin 1 through a jack 11 to facilitate adjusting the height of the hose fixing frame 4.
[0021] See also Figure 1 and Figure 5 The splash shield 5 is composed of a plurality of mutually hinged strip plates, so that it can be folded and placed when not in use, and can be erected and unfolded when needed.
[0022] See also Figure 1 and Figure 3 A filter frame 6 for holding tools is detachably connected to the oil collecting basin 1. The filter frame 6 has a filter screen to facilitate the draining of parts adhered with oil. An explosion-proof pneumatic wrench 7 for driving the jack 11 is placed in the filter frame 6.
[0023] See also Figure 1 and Figure 3 , and also includes a dust blowing gun 8. A fixing rod 104 is fixedly connected to the top of the oil collecting basin 1. The dust blowing gun 8 and the spray gun 3 are both hung on the fixing rod 104. The dust blowing gun 8 is used to blow away dust and impurities on the surface of the ground well joint and the coarse filter screen that need to be inspected and repaired, and can dry the ground well joint and the coarse filter screen after inspection and maintenance.
[0024] See also Figure 1 and Figure 3 A multi-air path row 9 is installed on the top of the oil collecting basin 1. The multi-air path row 9 includes an air inlet and three air outlets. The air inlet of the multi-air path row 9 is connected to the external air supply equipment through an air pipe, and the three air outlets of the multi-air path row 9 are respectively connected to the air inlets of the dust blowing gun 8, the explosion-proof pneumatic wrench 7 and the pneumatic oil pump 2 through air pipes.
[0025] As a preferred embodiment of the present invention: the multi-ventilation circuit row 9 can also be provided with another air outlet, the fourth air outlet is connected to the pressure regulating valve, the pressure regulating valve is connected to the PCV valve pipeline arranged on the ground well connector, and the PCV valve can be opened by gas pressure, which overcomes the problem of the prior art that the refueling truck needs to be started before opening the PCV valve. The PCV valve can be opened without starting the refueling truck, which is easy to operate; in addition, a pressure gauge is arranged on the pipeline between the pressure regulating valve and the PCV valve, so that the opening pressure of the PCV valve can be directly observed, and there is no need to perform additional tests on the opening pressure of the PCV valve.
[0026] The four corners of the bottom of the oil collecting basin 1 are connected with rollers 10, which are universal wheels to facilitate the movement of the device. At the same time, the working angle can be adjusted to the most comfortable position for the maintenance personnel, which is convenient for inspection and maintenance work.
[0027] Working principle: When the ground well joint and the coarse filter need to be repaired, the ground well hose is fixed by the hose fixing frame 4, and the hose fixing frame 4 is raised and lowered by the explosion-proof pneumatic wrench 7 to drive the jack 11 to meet the operation requirements at different heights, and then the dust impurities on the surface of the ground well joint and the coarse filter that need to be inspected and repaired are blown away by the dust gun 8, and then the staff manually repairs. During the maintenance process, the dirty oil retained in the ground well hose falls into the oil collecting basin 1, and the dirty oil naturally flows to the oil collecting tank 101 under the guidance of the inclined surface of the inner bottom of the oil collecting basin 1, and is filtered by the filter cartridge 102. When the ground well joint and the coarse filter need to be rinsed and cleaned, the splash guard 5 is removed. It is erected and expanded in the oil collecting basin 1 to form a protective barrier, and then the ground well joint and the coarse filter to be flushed are placed inside the splash shield 5, and the clean oil in the oil collecting tank 101 is extracted by the pneumatic oil pump 2, and then the ground well joint and the coarse filter are sprayed and cleaned by the spray gun 3. The splash shield 5 can prevent the oil generated during the flushing process from splashing and causing adverse effects on the environment and staff. The flushed oil will flow to the oil collecting tank 101 again under the guidance of the inclined surface, and will flow back to the oil collecting tank 101 after being filtered by the filter cartridge 102, so as to realize the recycling of the oil. After the flushing is completed, the ground well joint and the coarse filter are blown dry by the dust blowing gun 8.
[0028] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
