Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic pipeline maintenance technology, and more specifically, to a drain device for preventing liquid leakage at vertical pipe joints. Background Technology
[0002] In hydraulic and water system equipment sites, since most pipe connections use flange connections, long-term operation of the equipment will inevitably lead to leakage at the flange joints. In many production sites, pipeline equipment is arranged and installed in various ways, such as horizontally and vertically. When leakage occurs at the pipe joints, residual liquid in the pipes will inevitably flow out during disassembly. If the pipeline is arranged horizontally, it is only necessary to place an oil collection basin under the pipe joint. However, if the pipeline is arranged vertically, the residual liquid will flow down along the outer wall of the pipe, which will not only affect maintenance work, but also affect surrounding equipment and the external environment. Utility Model Content
[0003] The present invention aims to provide a drain device for preventing liquid leakage at vertical pipe joints, in order to solve the problems in the prior art where residual liquid flows down the outer wall of the pipe, the efficiency of inspection and maintenance work is low, and the equipment is greatly affected by the surrounding environment.
[0004] The embodiments of this utility model are implemented as follows:
[0005] This utility model embodiment provides a drain for preventing liquid leakage at vertical pipe joints, which includes an oil collection box body;
[0006] The aforementioned oil collection box body has a first half-shaped oil collection box and a second half-shaped oil collection box, and the first half-shaped oil collection box and the second half-shaped oil collection box are symmetrically distributed to each other.
[0007] The first and second split-type oil collection boxes are hinged together at their close ends and snap-fitted together at their far ends.
[0008] The upper inner sides of the first and second split-type oil collection boxes are respectively provided with a first semi-conical flow guide component and a second semi-conical flow guide component that are symmetrical and fit together. The first and second split-type oil collection boxes have a first arc-shaped oil collection groove and a second arc-shaped oil collection groove, respectively.
[0009] In use, the first and second half-section oil collection boxes of the oil collection box body are clamped onto the vertical section of the pipe. At this time, the first and second half-conical guide components are also clamped onto the vertical section of the pipe. Then, the first and second half-section oil collection boxes are interlocked and locked together. Under the weight of the oil collection box body, the inner and outer surfaces of the first and second half-conical guide components are tightly fitted with the vertical section of the pipe, the first arc-shaped oil collection groove, and the second arc-shaped oil collection groove, respectively. The oil leaking from the vertical section of the pipe will flow into the first and second arc-shaped oil collection grooves for collection.
[0010] The present embodiment discloses a drainer for preventing liquid leakage at vertical pipe joints. By providing a first and a second split-type oil collection box on the oil collection box body for sealing the outer wall of the vertical section of the pipe, as well as the first and second arc-shaped oil collection grooves for collecting oil, the leaked oil is less likely to flow downwards along the outer wall of the pipe. As a result, the drainer for preventing liquid leakage at vertical pipe joints has the beneficial effects of quickly collecting and draining residual liquid in the pipe, improving the efficiency of maintenance and repair work, and avoiding the impact of liquid leakage on the surrounding environment of the equipment.
[0011] Optionally: the first half-shaped oil collection box has a first arc-shaped outer wall and a first arc-shaped inner wall, and the second half-shaped oil collection box has a second arc-shaped outer wall and a second arc-shaped inner wall;
[0012] The first arc-shaped oil collecting groove is located between the first arc-shaped outer wall and the first arc-shaped inner wall, and the second arc-shaped oil collecting groove is located between the second arc-shaped outer wall and the second arc-shaped inner wall.
[0013] With this configuration, when the first and second half-shaped oil collection boxes are clamped in the vertical section of the pipe, the first and second half-conical flow guide components on the inner sides of the first and second arc-shaped inner walls can seal the outer wall of the vertical section of the pipe, allowing leaked liquid to flow into the first and second arc-shaped oil collection tanks along the outer walls of the first and second arc-shaped inner walls, thus quickly collecting the liquid and preventing residual liquid from flowing downwards along the outer wall of the vertical section of the pipe.
[0014] Optionally: The inner side of the first arc-shaped inner wall is provided with a first conical groove, and the first semi-conical flow guide component is detachably embedded in the interior of the first conical groove;
[0015] The inner side of the second arc-shaped inner wall is provided with a second conical groove, and the second semi-conical flow guide component is detachably embedded inside the second conical groove.
[0016] With this configuration, after the first and second half-section oil collection boxes are installed on the vertical section of the pipeline, due to their own weight, the oil collection boxes will drop a short distance downwards. At this time, the first and second half-conical guide components will be stuck on the inner inclined surfaces of the first and second conical grooves, thereby achieving a better sealing effect.
[0017] Optionally, the conical outer walls of the first semi-conical guide component and the second semi-conical guide component are clearance-fitted with the conical groove walls of the first conical groove and the second conical groove.
[0018] With this configuration, when the first and second half-conical oil collection boxes are installed on the vertical section of the pipeline, the outer inclined surfaces of the first and second half-conical guide components fit tightly against the inner inclined surfaces of the first and second conical grooves under their own weight, meaning there is no gap between the two inclined surfaces. Since the first and second half-conical guide components are made of soft rubber material, to achieve a better sealing effect, an external force can be applied to pull the oil collection box body downwards, causing the upper part of the oil collection box body to be squeezed against the first and second half-conical guide components, making them fit even more tightly.
[0019] Optionally, the bottom of the first conical groove and the second conical groove are respectively provided with a first arc-shaped track and a second arc-shaped track. The first semi-conical flow guide component and the second semi-conical flow guide component are respectively provided with a first arc-shaped groove and a second arc-shaped groove at one end near the bottom of the first conical groove and the second conical groove. The first arc-shaped groove and the second arc-shaped groove are respectively slidably clamped on the first arc-shaped track and the second arc-shaped track.
[0020] This configuration facilitates the installation and confinement of the first and second semi-conical flow guide components within the first and second conical grooves, preventing accidental detachment of the first and second semi-conical flow guide components.
[0021] Optionally, the inner diameters of the first semi-conical guide component and the second semi-conical guide component are smaller than the inner diameters of the first arc-shaped inner wall and the second arc-shaped inner wall.
[0022] This design ensures that the oil collection box fits snugly when installed on the vertical section of the pipeline.
[0023] Optionally, both the first semi-conical guide component and the second semi-conical guide component are made of soft rubber material.
[0024] This design, using a soft rubber material, allows the first and second semi-conical flow guide components to have elastic deformation, which helps to improve the sealing effect of the first and second semi-conical flow guide components.
[0025] Optionally: the first arc-shaped oil collecting groove and the second arc-shaped oil collecting groove are interconnected, and the bottom of the first arc-shaped oil collecting groove is provided with a drainage hole, and the outer end of the drainage hole is connected to a drainage pipe.
[0026] With this configuration, the leaked oil collected by the first and second arc-shaped oil collection tanks will be discharged through the drainage holes and drainage pipes, facilitating the centralized collection of leaked oil and preventing residual liquid from flowing down the outer wall of the pipes, thereby avoiding impact on the surrounding environment and the outside world.
[0027] Optionally: the mating surface of the first split-type oil collection box has a first U-shaped sealing groove and a second U-shaped sealing groove, and the mating surface of the second split-type oil collection box has a third U-shaped sealing groove and a fourth U-shaped sealing groove, and the first U-shaped sealing groove and the second U-shaped sealing groove are symmetrically distributed with respect to the third U-shaped sealing groove and the fourth U-shaped sealing groove.
[0028] The first U-shaped sealing groove and the second U-shaped sealing groove are respectively equipped with a first rubber sealing strip and a second rubber sealing strip.
[0029] With this configuration, using the first rubber sealing strip and the second rubber sealing strip, leakage is less likely to occur at the joint between the first arc-shaped oil collection groove and the second arc-shaped oil collection groove.
[0030] Optionally: The first and second split-type oil collection boxes are provided with interlocking arc-shaped locking plates and locking teeth at their respective ends. One side of the arc-shaped locking plate is hinged to the outer wall of the first split-type oil collection box at the end away from the second split-type oil collection box, and the locking teeth are fixedly connected to the outer wall of the second split-type oil collection box at the end away from the first split-type oil collection box.
[0031] In this configuration, the aforementioned arc-shaped card is made of thin stainless steel with a good elastic coefficient and has an arc-shaped design. In its natural state, the length of the aforementioned arc-shaped card is slightly less than the distance to the aforementioned snap teeth. When the aforementioned first half-shaped oil collection box and the aforementioned second half-shaped oil collection box are closed together, the arc-shaped card is pressed to extend its length and thus lock onto the aforementioned snap teeth. Since the aforementioned arc-shaped card has a certain elasticity, it can ensure that the aforementioned arc-shaped card will not loosen or fall off, which is conducive to maintaining the closed state after the aforementioned first half-shaped oil collection box and the aforementioned second half-shaped oil collection box are closed together.
[0032] Optionally, a pivot hinge is provided between the ends of the first and second split-type oil collection boxes that are close to each other.
[0033] With this configuration, the first and second split-type oil collection boxes can be opened and closed by using the aforementioned pivot-type hinges, making it easier for the first and second split-type oil collection boxes to be clamped on the vertical section of the pipe and assembled into the oil collection box body.
[0034] In summary, the drainer disclosed in this utility model for preventing liquid leakage at vertical pipe joints has the beneficial effects of quickly collecting and draining residual liquid in the pipe, improving the efficiency of maintenance and repair work, and preventing liquid leakage from affecting the surrounding environment of the equipment.

[0042] Example
[0043] See Figure 1 , Figure 2 and Figure 3 This embodiment proposes a drain device for preventing liquid leakage at vertical pipe joints, including an oil collection box 1;
[0044] The oil collection box 1 has a first half-shaped oil collection box 2 and a second half-shaped oil collection box 3, which are symmetrically distributed.
[0045] The first half-shaped oil collection box 2 and the second half-shaped oil collection box 3 are hinged together at their close ends, and snapped together at their far ends.
[0046] The upper inner sides of the first half-type oil collection box 2 and the second half-type oil collection box 3 are respectively provided with a first half-conical flow guide component 4 and a second half-conical flow guide component 5 that are symmetrical and fit together. The first half-type oil collection box 2 and the second half-type oil collection box 3 respectively have a first arc-shaped oil collection groove 6 and a second arc-shaped oil collection groove 7.
[0047] In use, the first half-shaped oil collection box 2 and the second half-shaped oil collection box 3 of the oil collection box body 1 are clamped onto the vertical section of the pipe. At this time, the first half-conical guide component 4 and the second half-conical guide component 5 are also clamped onto the vertical section of the pipe. Then, the first half-shaped oil collection box 2 and the second half-shaped oil collection box 3 are interlocked and locked together. Under the weight of the oil collection box body 1, the inner and outer surfaces of the first half-conical guide component 4 and the second half-conical guide component 5 are tightly fitted with the vertical section of the pipe, the first arc-shaped oil collection groove 6 and the second arc-shaped oil collection groove 7, respectively. The oil leaking from the vertical section of the pipe will flow into the first arc-shaped oil collection groove 6 and the second arc-shaped oil collection groove 7 for centralized collection.
[0048] The present embodiment discloses a drainer for preventing liquid leakage at vertical pipe joints. By setting a first half-shaped oil collection box 2 and a second half-shaped oil collection box 3 on the oil collection box body 1 for sealing the outer wall of the vertical section of the pipe, as well as a first arc-shaped oil collection groove 6 and a second arc-shaped oil collection groove 7 for collecting oil, the leaked oil is less likely to flow down the outer wall of the pipe. Thus, the drainer for preventing liquid leakage at vertical pipe joints has the beneficial effects of quickly collecting and draining residual liquid in the pipe, improving the efficiency of maintenance and repair work, and avoiding the impact of liquid leakage on the surrounding environment of the equipment.
[0049] See Figure 1 , Figure 2 and Figure 3 The first half-shaped oil collection box 2 has a first arc-shaped outer wall 8 and a first arc-shaped inner wall 9, and the second half-shaped oil collection box 3 has a second arc-shaped outer wall 10 and a second arc-shaped inner wall 11.
[0050] The first arc-shaped oil collecting trough 6 is located between the first arc-shaped outer wall 8 and the first arc-shaped inner wall 9, and the second arc-shaped oil collecting trough 7 is located between the second arc-shaped outer wall 10 and the second arc-shaped inner wall 11. When the first half-shaped oil collecting box 2 and the second half-shaped oil collecting box 3 are clamped in the vertical section of the pipe, the first semi-conical flow guiding component 4 and the second semi-conical flow guiding component 5 on the inner side of the first arc-shaped inner wall 9 and the second arc-shaped inner wall 11 can seal the outer wall of the vertical section of the pipe, so that the leaked liquid flows into the first arc-shaped oil collecting trough 6 and the second arc-shaped oil collecting trough 7 along the outer side of the first arc-shaped inner wall 9 and the second arc-shaped inner wall 11, which plays a role in quickly collecting liquid and preventing residual liquid from flowing down the outer wall of the vertical section of the pipe.
[0051] The inner side of the first arc-shaped inner wall 9 is provided with a first conical groove 12, and the first semi-conical flow guide component 4 is detachably embedded in the interior of the first conical groove 12; the inner side of the second arc-shaped inner wall 11 is provided with a second conical groove 13, and the second semi-conical flow guide component 5 is detachably embedded in the interior of the second conical groove 13. This arrangement allows the first half-conical oil collection box 2 and the second half-conical oil collection box 3 to be installed on the vertical section of the pipeline. Due to the weight of the oil collection box body 1, the oil collection box body 1 will fall downward a short distance. At this time, the first semi-conical flow guide component 4 and the second semi-conical flow guide component 5 will be stuck on the inner inclined surface of the first conical groove 12 and the second conical groove 13, thereby enabling the first semi-conical flow guide component 4 and the second semi-conical flow guide component 5 to achieve a better sealing effect.
[0052] The conical outer walls of the first semi-conical guide component 4 and the second semi-conical guide component 5 are in clearance fit with the conical groove walls of the first conical groove 12 and the second conical groove 13. When the first half-type oil collection box 2 and the second half-type oil collection box 3 are installed on the vertical section of the pipeline, due to the clearance fit between the first semi-conical guide component 4 and the second semi-conical guide component 5 and the first conical groove 12 and the second conical groove 13, the outer inclined surfaces of the first semi-conical guide component 4 and the second semi-conical guide component 5 are tightly attached to the inner inclined surfaces of the first conical groove 12 and the second conical groove 13 under their own weight, that is, there is no gap between the two inclined surfaces. Since the first semi-conical guide component 4 and the second semi-conical guide component 5 are made of soft rubber material, in order to achieve a better sealing effect, the oil collection box 1 can be pulled down with appropriate external force, so that the upper part of the oil collection box 1 is squeezed with the first semi-conical guide component 4 and the second semi-conical guide component 5, making them fit more tightly.
[0053] See Figure 1 , Figure 2 and Figure 3 The bottom of the first conical groove 12 and the second conical groove 13 are respectively provided with a first arc-shaped track 14 and a second arc-shaped track 15. The first semi-conical guide component 4 and the second semi-conical guide component 5 are respectively provided with a first arc-shaped groove 16 and a second arc-shaped groove 17 at one end near the bottom of the first conical groove 12 and the second conical groove 13. The first arc-shaped groove 16 and the second arc-shaped groove 17 are respectively slidably clamped on the first arc-shaped track 14 and the second arc-shaped track 15. This is conducive to the installation and confinement of the first semi-conical guide component 4 and the second semi-conical guide component 5 in the first conical groove 12 and the second conical groove 13, and avoids the first semi-conical guide component 4 and the second semi-conical guide component 5 from accidentally falling off.
[0054] The inner diameters of the first semi-conical guide component 4 and the second semi-conical guide component 5 are smaller than the inner diameters of the first arc-shaped inner wall 9 and the second arc-shaped inner wall 11, which ensures that the oil collection box 1 can fit tightly when installed on the vertical section of the pipeline.
[0055] The first semi-conical guide component 4 and the second semi-conical guide component 5 are both made of soft rubber material. The use of soft rubber material allows the first semi-conical guide component 4 and the second semi-conical guide component 5 to have elastic deformation, which helps to improve the sealing effect of the first semi-conical guide component 4 and the second semi-conical guide component 5.
[0056] The first arc-shaped oil collecting tank 6 and the second arc-shaped oil collecting tank 7 are interconnected. The bottom of the first arc-shaped oil collecting tank 6 is provided with a drainage hole 18, and the outer end of the drainage hole 18 is connected to a drainage pipe 19. The leaked oil collected by the first arc-shaped oil collecting tank 6 and the second arc-shaped oil collecting tank 7 will be discharged through the drainage hole 18 and the drainage pipe 19, which facilitates the centralized collection of leaked oil and prevents residual liquid from flowing down the outer wall of the pipe, thereby avoiding the impact on the surrounding environment of the equipment and the outside world.
[0057] See Figure 1 , Figure 2 and Figure 3 The first split-type oil collection box 2 has a first U-shaped sealing groove 20 and a second U-shaped sealing groove 21 on its mating surface, and the second split-type oil collection box 3 has a third U-shaped sealing groove 28 and a fourth U-shaped sealing groove 22 on its mating surface. The first U-shaped sealing groove 20 and the second U-shaped sealing groove 21 are symmetrically distributed with respect to the third U-shaped sealing groove 28 and the fourth U-shaped sealing groove 22. A first rubber sealing strip 23 and a second rubber sealing strip 24 are respectively installed in the grooves of the first U-shaped sealing groove 20 and the second U-shaped sealing groove 21. The use of the first rubber sealing strip 23 and the second rubber sealing strip 24 can prevent leakage at the joint between the first arc-shaped oil collection groove 6 and the second arc-shaped oil collection groove 7.
[0058] The first and second split-type oil collecting boxes 2 and 3 are respectively provided with interlocking arc-shaped clamping plates 25 and interlocking teeth 26 at their respective ends. One side of the arc-shaped clamping plate 25 is hinged to the outer wall of the end of the first split-type oil collecting box 2 away from the second split-type oil collecting box 3, and the interlocking teeth 26 are fixedly connected to the outer wall of the end of the second split-type oil collecting box 3 away from the first split-type oil collecting box 2. The arc-shaped clamping plate 25 is made of thin stainless steel with good elasticity and has an arc-shaped design. In its normal state, the length of the arc-shaped plate 25 is slightly less than the distance to the buckle 26. When the first half-shaped oil collection box 2 and the second half-shaped oil collection box 3 are closed together, the arc-shaped plate 25 is pressed to extend its length and then locks onto the buckle 26. Since the arc-shaped plate 25 has a certain elasticity, it can ensure that the arc-shaped plate 25 will not loosen or fall off, which is conducive to maintaining the closed state after the first half-shaped oil collection box 2 and the second half-shaped oil collection box 3 are closed together.
[0059] A pivot hinge 27 is hinged between the ends of the first half-type oil collection box 2 and the second half-type oil collection box 3 that are close to each other. By using the pivot hinge 27, the first half-type oil collection box 2 and the second half-type oil collection box 3 can be opened and closed, so that the first half-type oil collection box 2 and the second half-type oil collection box 3 can be clamped on the vertical section of the pipe and combined to form the oil collection box body 1.
[0060] See Figure 1 , Figure 2 and Figure 3 The specific operating principle of the drain device used to prevent liquid leakage at vertical pipe joints in this embodiment is as follows:
[0061] First, when leakage occurs at the joint of the vertical pipe section, the workers install the first semi-conical guide component 4 and the second semi-conical guide component 5 along the first arc-shaped track 14 and the second arc-shaped track 15 into the first conical groove 12 and the second conical groove 13. Then, the first half-shaped oil collection box 2 and the second half-shaped oil collection box 3 are clamped onto the vertical pipe section, so that the first semi-conical guide component 4 and the second semi-conical guide component 5 are tightly attached to the vertical pipe section. The first rubber sealing strip 23 and the second rubber sealing strip 24 are tightly clamped between the first U-shaped sealing groove 20 and the second U-shaped sealing groove 21 and the third U-shaped sealing groove 28 and the fourth U-shaped sealing groove 22 to prevent leakage from the first arc-shaped oil collection groove 6 and the second arc-shaped oil collection groove 7. Next, press the elastic arc-shaped clamp 25 to lock it onto the snap teeth 26. At this point, the oil collection box 1 is completely fitted onto the outer wall of the vertical section pipe. Then, the operator can press down on the oil collection box 1, causing the inner walls of the first semi-conical guide component 4 and the second semi-conical guide component 5 to press against the outer wall of the vertical section pipe. The outer inclined surfaces of the first semi-conical guide component 4 and the second semi-conical guide component 5 press against the inner inclined surfaces of the first conical groove 12 and the second conical groove 13, making the connection more sealed and facilitating the flow of leaked oil from the vertical section pipe into the first arc-shaped oil collection groove 6 and the second arc-shaped oil collection groove 7, and finally conveniently discharged through the drainage hole 18 and the drainage pipe 19.
[0062] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
