Description

Technical Field

[0001] This utility model relates to the field of pump maintenance and cleaning technology, and in particular to a pump cleaning tool. Background Technology

[0002] Currently, each station in the gas field's gas production management area has a certain number of moving equipment, such as diaphragm pumps, centrifugal pumps, screw pumps, and gear pumps. After long-term operation, due to the failure of the seals or the aging and wear of the pump parts, oil leakage or other abnormalities may occur, requiring the pumps to be taken offline for maintenance. During maintenance, the internal oil tank of the pump must also be cleaned and maintained.

[0003] When cleaning and maintaining the pump oil tank, on-site operators typically use a clean cloth to reach inside and remove oil stains. However, this requires reaching inside the tank and specifically touching the oil stains before applying pressure, then vigorously wiping away the stains repeatedly. Due to the complex internal structure of the pump, with its curves and dead angles, and limited operating space, coupled with the viscosity of the oil stains, the cloth becomes sticky and slippery after wiping, making cleaning difficult and increasing the risk of injury. Furthermore, some oil stains are difficult to reach by hand, resulting in incomplete cleaning. If the pump oil tank is not thoroughly cleaned, new oil may deteriorate or emulsify after being injected.

[0004] In addition, if sewage pumps or other pumps experience an emergency at night, the dim lighting makes it difficult for operators to effectively handle the situation and clean up grease. If they are not repaired and reinstalled in time, sewage leaks or reverse towers may occur at the plant, which could trigger a plant shutdown in severe cases.

[0005] Therefore, there is a need for a cleaning tool suitable for pump maintenance and cleaning that can safely, efficiently, and cost-effectively solve the problem of difficult oil stain removal during pump maintenance. Utility Model Content

[0006] The purpose of this utility model is to provide a pump cleaning tool to address the problem that in the existing technology, when cleaning oil stains in the pump oil tank, operators need to put their hands into the pump oil tank to clean it with a cloth, which is easy to get injured during the cleaning process and makes it difficult to clean the oil stains because it is difficult for human hands to reach them.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A pump cleaning tool includes a telescopic rod and a plate structure. The telescopic rod is adjustable in length. The upper surfaces of the telescopic rod and the plate structure are hinged together. The lower surface of the plate structure is provided with a wiping component. The telescopic rod is equipped with a switch. A light is provided on the side of the plate structure. The switch and the light are connected.

[0009] This utility model provides a cleaning tool for pump maintenance and cleaning. The length of the telescopic rod can be adjusted to a suitable length, and the relative angle between the insert plate structure and the telescopic rod can be adjusted to a suitable position to facilitate the cleaning of oil stains. In use, pressure can be applied to the insert plate structure by holding the telescopic rod, thereby moving the telescopic rod and causing the insert plate structure to move along the inner wall of the pump's oil tank. The wiping component then wipes away the oil stains, avoiding the difficulty of cleaning the pump's oil tank due to the operator's inability to reach or insert the tool. This cleaning tool achieves better cleaning results. Even in low-light conditions, the lighting can be controlled by a switch to illuminate the operator, facilitating effective on-site handling and oil stain cleaning. The switch can be connected to the lighting via wired or wireless means to control its operation.

[0010] Using the above-mentioned cleaning tools for pump maintenance and cleaning saves time and effort, reduces the risk of injury to operators, and can safely, efficiently and cost-effectively solve the problem of difficult oil stain cleaning of pumps due to the inability of people to reach or access the equipment, or due to poor lighting. The above-mentioned cleaning tools can effectively reduce the difficulty of oil stain cleaning and have a good cleaning effect.

[0011] The hinge structure of the telescopic rod and the insert plate can be connected by either a planar revolute joint or a ball revolute joint.

[0012] As a preferred embodiment of this utility model, the telescopic rod is a hollow tubular structure, comprising several pipe segments, with adjacent pipe segments nested together, and two adjacent pipe segments slidably connected and fixed by a locking mechanism. The structure is simple and the cost is low.

[0013] As other possible implementation methods, the telescopic rod can also be adjusted in length using pneumatic or hydraulic means, and is not limited to the examples mentioned above.

[0014] As a preferred embodiment of this utility model, the number of pipe segments is set to N levels, where N≥2 and N is an integer. Among all the pipe segments, the Nth level pipe segment has the largest size, and the first level pipe segment is hinged to the insert plate structure. That is, from the position of the insert plate structure, the diameter of the Nth level pipe segment of the telescopic rod increases. For example, the diameter of the first level pipe segment is smaller than that of the second level pipe segment, the diameter of the second level pipe segment is smaller than that of the third level pipe segment, and so on, with the diameter of the i-th level pipe segment being smaller than that of the (i+1)-th level pipe segment (i+1≤N). This facilitates the application of force, and the smaller end of the telescopic rod can better adapt to the small space of the pump oil tank.

[0015] As another possible implementation, when the Nth-level pipe section has the largest size, the end of the Nth-level pipe section can be hinged to the insert plate structure, that is, the pipe diameter changes from the position of the telescopic rod to the insert plate structure.

[0016] As a further preferred embodiment of this utility model, a first protrusion structure is provided on the lower outer peripheral surface of each pipe segment, and the first protrusion structure has the functions of limiting and positioning.

[0017] As a preferred embodiment of this utility model, each of the pipe segments in the first N-1 stages near the insert plate structure, i.e., each pipe segment from stage 1 to stage N-1, is provided with the locking mechanism. The locking mechanism includes an elastic member and a second protrusion structure. One end of the elastic member is fixedly connected to the side wall of the pipe segment, and the other end of the elastic member is fixedly connected to the second protrusion structure. The elastic member can drive the second protrusion structure to extend and retract. The second protrusion structure penetrates the side wall of the corresponding pipe segment. In the last N-1 stages (i.e., the N-1 stages away from the insert plate structure), i.e., each pipe segment from stage 2 to stage N, a plurality of positioning holes are provided at intervals along the axial direction. The positioning holes correspond to the positions of the second protrusion structures.

[0018] During the adjustment of the telescopic rod length, by pressing the second protruding structure, the second protruding structure retracts a certain distance. At this time, when sliding the upper level or the current pipe section, the second protrusion can always act on the inner wall of the upper level pipe section of the current pipe section under the action of the elastic component until it slides to the designated positioning hole position. The second protruding structure can then reset and pop out at the positioning hole for snap-locking.

[0019] The aforementioned elastic component can be a compression spring, a balance spring, or a tension spring, etc., as long as it can withstand axial pressure within the pipe section and has a certain rebound force.

[0020] In the case where the pipe segment is limited by the second protrusion structure and the positioning hole buckle fixing method described above, as a further preferred embodiment of this utility model, a trajectory groove is provided on the side wall of each pipe segment. The trajectory groove is arranged in the axial direction and can be used to guide the pipe segment to slide, so as to quickly position it to the positioning hole.

[0021] As another preferred embodiment of this utility model, the number of pipe segments is two, namely a first pipe segment and a second pipe segment. The lower end of the first pipe segment is hinged to the insert plate structure, and the second pipe segment is nested inside the first pipe segment. The locking mechanism is a locking screw threaded to the outer circumferential surface of the upper end of the first pipe segment. The locking screw passes through the side wall of the first pipe segment and abuts against the outer circumferential surface of the second pipe segment.

[0022] As a preferred embodiment of this utility model, a track groove is provided on the side wall of the second pipe section along the length direction. The position of the track groove corresponds to the position of the locking screw, which makes it easier for the locking screw to be inserted into the track groove of the second pipe section, and the structure is more stable.

[0023] In a preferred embodiment of this invention, the wiping component and the insert structure are detachably connected, and the wiping component is made of a sponge. A sponge has better absorbency and a stronger cleaning effect than a cloth.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0025] The pump cleaning tool provided by this utility model can adapt to the location of oil stains by adjusting the length and angle of the telescopic rod, avoiding the situation where it is difficult to clean the pump oil tank because the operator's hand cannot reach it. It has a good cleaning effect, saves time and effort, and has a low risk of injury to the operator. Even in low light conditions, the operator can carry out effective on-site treatment and oil stain removal under lighting. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0038] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use.

[0043] Example 1

[0044] A pump cleaning tool, such as Figures 1-7 As shown, it includes a telescopic rod 1 and a plate structure 2. The length of the telescopic rod 1 is adjustable. The upper surfaces of the telescopic rod 1 and the plate structure 2 are hinged together. The lower surface of the plate structure 2 is provided with a wiping component 4. The telescopic rod 1 is provided with a switch 8. The side of the plate structure 2 is provided with a light 6. The switch 8 and the light 6 are connected.

[0045] Using the above-mentioned cleaning tools for pump maintenance and cleaning allows for adjustment of the length of the telescopic rod 1 to a suitable length and the relative angle between the insert plate structure 2 and the telescopic rod 1 to a suitable position, facilitating the cleaning of oil stains. During use, pressure is applied to the insert plate structure 2 by holding the telescopic rod 1, thereby moving the telescopic rod 1 and driving the insert plate structure 2 to move along the inner wall of the pump's oil tank. The oil stains are then wiped away by the wiping component 4, avoiding the difficulty of cleaning the pump's oil tank due to the operator's inability to reach or insert the components. Using these cleaning tools achieves better cleaning results. Even in low-light conditions, the lighting 6 can be controlled by the switch 8 to provide illumination for the operator, facilitating effective on-site handling and oil stain removal.

[0046] Specifically, in this embodiment, the telescopic rod 1 is a hollow tubular structure. The telescopic rod 1 includes several pipe segments, with adjacent pipe segments nested together. The adjacent pipe segments are slidably connected and can be fixed by a locking mechanism. The structure is simple and the cost is low.

[0047] Assuming there are N levels of pipe segments, where N≥2 and N is an integer, in this embodiment, the Nth level pipe segment is preferably set to have the largest size, and the first level pipe segment is hinged to the insert plate structure 2. That is, from the position of the insert plate structure 2, the pipe diameter of the N levels of the telescopic rod 1 increases. For example, the pipe diameter of the first level pipe segment is smaller than that of the second level pipe segment, the pipe diameter of the second level pipe segment is smaller than that of the third level pipe segment, and so on, with the pipe diameter of the i-th level pipe segment being smaller than that of the (i+1)-th level pipe segment (i+1≤N). This facilitates the application of force, and the smaller end of the telescopic rod 1 can better adapt to the small space of the pump oil tank.

[0048] A first protrusion structure 5 is provided on the lower outer circumferential surface of each pipe section. The first protrusion structure 5 has a limiting and positioning function. In this embodiment, the first protrusion structure 5 is preferably a boss structure provided along the circumference of the pipe section.

[0049] Furthermore, such as Figure 4 , Figure 5As shown, to adjust the length of the telescopic rod 1, a locking mechanism is provided in the pipe sections of the first N-1 stages near the insert plate structure 2. In this embodiment, the locking mechanism includes an elastic member 10 and a second protruding structure 11. One end of the elastic member 10 is fixedly connected to the side wall of the pipe section, and the other end of the elastic member 10 is fixedly connected to the second protruding structure 11. The elastic member 10 can drive the second protruding structure 11 to move in a straight line. The second protruding structure 11 penetrates the side wall of the corresponding pipe section. The pipe sections of the last N-1 stages (i.e., the N-1 stages away from the insert plate structure 2) are provided with a plurality of positioning holes 12 at intervals along the axial direction. The positioning holes 12 correspond to the positions of the second protruding structure 11. During the adjustment of the telescopic rod 1 length, by pressing the second protruding structure 11, the second protruding structure 11 retracts a certain distance. At this time, when sliding the upper level or the current pipe segment, the second protrusion can always act on the inner wall of the upper level pipe segment under the elastic action of the elastic member 10 until it slides to the designated positioning hole 12 position. The second protruding structure 11 can then reset and pop out at the positioning hole 12 for locking. In this embodiment, the elastic member 10 is preferably a compression spring. Further, the locking mechanism also preferably includes a sleeve 15, which is laterally arranged in the corresponding pipe segment. The elastic member 10 is arranged in the sleeve 15. The sleeve 15 provides structural support and guidance for the axial movement of the elastic member 10 and the second protruding structure 11, which can reduce the influence of the elastic member 10 bending deformation due to gravity and prevent the second protruding structure 11 from falling off due to excessive pressing.

[0050] In the case where the pipe segment is limited by using the second protrusion structure 11 and the positioning hole 12 for snap-fit ​​fixing, as a further preferred embodiment of this invention, a trajectory groove 9 can be provided on the side wall of each pipe segment. The trajectory groove 9 is provided along the axial direction and can be used to guide the pipe segment to slide, so as to quickly position it to the positioning hole 12. The positioning hole 12 can be provided in the trajectory groove 9.

[0051] This embodiment uses a three-stage pipe section as an example (i.e., N=3) for illustration: The telescopic rod 1 is divided into three sections from top to bottom: upper, middle, and lower. The first-stage pipe section closest to the insert plate structure 2 is designated as the first pipe section 101, the second-stage pipe section in the middle is designated as the second pipe section 102, and the third-stage pipe section at the top is designated as the third pipe section 103. The first pipe section 101 is nested within the second pipe section 102, and the second pipe section 102 is nested within the third pipe section 103. In the first two stages, i.e., the first pipe section 101 and the second pipe section 102, a locking mechanism and a first protruding structure 5 are respectively provided. The locking mechanism is used to lock the position of the next-stage pipe section and is positioned near the upper end of the corresponding pipe section; for example... Figure 5 , Figure 7As shown, positioning holes 12 corresponding to the locking mechanism of the preceding pipe section are respectively provided on the latter two stages, namely the second pipe section 102 and the third pipe section 103. The positioning holes 12 on the second pipe section 102 are used to limit and fix the second protruding structure 11 on the first pipe section 101, and the positioning holes 12 on the third pipe section 103 are used to limit and fix the second protruding structure 11 on the second pipe section 102. Track grooves 9 are provided on all three pipe sections. The track grooves 9 on the first pipe section 101 can be adapted to be embedded in the track grooves 9 on the second pipe section 102, and the track grooves 9 on the second pipe section 102 can be adapted to be embedded in the track grooves 9 on the third pipe section 103. The track grooves 9 on each pipe section are provided with equal cross-sections. The third pipe section 103 can extend and retract relative to the second pipe section 102, and the second pipe section 102 can extend and retract relative to the first pipe section 101. When a shorter length is required, the third pipe section 103 can be positioned close to the first protruding structure 5 on the second pipe section 102, and the second pipe section 102 can be positioned close to the first protruding structure 5 on the first pipe section 101. The first protruding structure 5 can act as a lower limit. When it is necessary to extend the telescopic rod 1, one hand can hold the first protruding structure 5 on a certain pipe section, and the other hand can press the second protruding structure 11 on another pipe section to adjust the length until the second protruding structure 11 slides to the designated position. Then, the second protruding structure 11 is fixed with the positioning hole 12 at the corresponding position, which facilitates the cleaning of oil stains in the pump tank.

[0052] Furthermore, in this embodiment, the switch 8 is connected to the lighting lamp 6 via a flexible cable 7. A through hole is provided on the upper section of the telescopic rod 1, i.e., the third pipe section 103, and the switch 8 is fixed to the through hole in the upper section; as shown... Figure 4 , Figure 5 As shown, the sleeve 15 of the locking mechanism has a first wire hole 131 for the cable 7 to pass through; Figure 5 , Figure 6As shown, a hinge joint 13 is provided at the lower end of the telescopic rod 1. A hinge hole and a second wire-passing hole 151 are provided at the hinge joint 13. The end of the telescopic rod 1 is sealed to prevent oil from entering the pipe. The cable 7 passes through the second wire-passing hole 151 at the end of the telescopic rod 1 and is wrapped with a wire sleeve to the insertion plate structure 2. The cable 7 is electrically connected to the internal wiring of the insertion plate structure 2. The wire sleeve isolates oil, protecting the cable 7. Correspondingly, a hinge seat 14 is provided on the upper surface of the insertion plate structure 2. The hinge joint 13 and the hinge seat 14 are rotatably connected at the hinge hole by a pin, allowing the telescopic rod 1 to move 180°. By rotating and extending the telescopic rod 1, oil in the dead corners inside the pump can be effectively cleaned, shortening the pump maintenance time and saving time and effort. Furthermore, in this embodiment, the insert structure 2 is rectangular, and the telescopic rod 1 is preferably rotatably set along one side of the length direction of the insert structure 2. In this way, when encountering a narrow space, the narrower side of the insert structure 2 can be used to reach into the dead corner for cleaning, which has good adaptability to working conditions. At the same time, the telescopic rod 1 can be rotated and adjusted to the side away from the dead corner, which has a better cleaning effect.

[0053] In this embodiment, through holes are arranged around the perimeter of the insert structure 2, such as... Figure 1 , Figure 2 As shown, the lighting lamps 6 are evenly distributed across the through-hole in a 360° pattern, with a total of 12 groups. The interval between adjacent groups is 30° to ensure no blind spots in lighting. The lighting lamps 6 are controlled by a switch 8 on the upper section of the retractable segment. The switch 8 controls the indicator lights by pressing them. The lighting lamps 6 use LED indicator lights.

[0054] By adding lighting lamp 6, the lighting problem for pump maintenance and cleaning can be effectively solved when visibility is poor in low light conditions, saving manpower.

[0055] Furthermore, in this embodiment, the wiping component 4 and the insert structure 2 are detachably connected. A hook-and-loop fastener structure 3 is provided at the bottom of the insert structure 2, which can connect the wiping component 4 using adhesive or snap-fit ​​methods. In this embodiment, the wiping component 4 is preferably made of sponge, and the back of the sponge can be fixedly connected to the insert structure 2 via Velcro. Sponges have better absorbency and stronger cleaning effect than cloths. The detachable insert structure 2 allows for the design of sponges or towels of different types and materials for wiping oil stains, and allows for quick disassembly, ensuring thorough cleaning and extending the service life of the pump.

[0056] Using the aforementioned cleaning tools for pump maintenance and cleaning saves time and effort, reduces the risk of injury to operators, and safely, efficiently, and cost-effectively solves the problem of difficult oil removal during pump maintenance due to limitations in accessibility or poor lighting. These tools effectively reduce the difficulty of oil removal, facilitate thorough cleaning, and provide better cleaning results. Compared to existing cleaning methods, these tools are more suitable for oil removal during pump maintenance and are applicable to environments with poor visibility.

[0057] Example 2

[0058] Compared to Example 1, the difference in this example lies in the specific structural form of the locking mechanism used to fix two adjacent pipe sections. Specifically, as shown in Example 1... Figure 8 , Figure 9 As shown, in this embodiment, there are two pipe segments, i.e., N=2, namely the first pipe segment 101 and the second pipe segment 102; the lower end of the first pipe segment 101 is used to be hinged to the insert plate structure 2, and the second pipe segment 102 is nested inside the first pipe segment 101; the locking mechanism is a locking screw 16 threaded to the outer circumferential surface of the upper end of the first pipe segment 101, and the locking screw 16 passes through the side wall of the first pipe segment 101 and abuts against the outer circumferential surface of the second pipe segment 102.

[0059] Furthermore, a track groove 9 is provided along the length direction on the side wall of the second pipe section 102. The position of the track groove 9 corresponds to the position of the locking screw 16, which makes it easier for the locking screw 16 to be better inserted into the track groove 9 of the second pipe section 102, and the structure is more stable.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
