Description

Technical Field

[0001] This application relates to the field of downhole operation equipment technology, and in particular to a switching device for a valve at a high position inside a well. Background Technology

[0002] Currently, manholes, as an important component of urban infrastructure, are widely used in water supply, drainage, and fire protection systems. In these systems, the operation of valves is crucial for their normal operation. With the acceleration of urbanization, the space within manholes is becoming increasingly compact. Therefore, operating valves located at high positions within manholes faces numerous challenges. Especially in underground construction environments, workers often find it difficult to operate handle-type valves at high positions within the manhole due to the limited space, causing significant inconvenience for daily maintenance.

[0003] In actual construction, to solve the problem of opening and closing handle-type valves located at high positions in the well, the usual method is for workers to use ladders to climb to the high position in the well and directly turn the handle of the handle-type valve by hand to achieve the opening and closing operation.

[0004] The main drawback of the above method is that workers need to climb ladders to reach a high position and manually close the valve. This method is very inconvenient in the confined space of the well, resulting in low operational efficiency and easy soiling of workers' clothing due to the presence of sludge in the well. Therefore, to solve the problem of the inconvenience of traditional valve opening and closing methods at high positions in wells, this application proposes an opening and closing device for valves at high positions in wells. Utility Model Content

[0005] To address the inconvenience of traditional methods for switching valves at high locations within wells, this application provides a switching device for valves at high locations within wells.

[0006] This application provides a switching device for a valve at a high position inside a well, which adopts the following technical solution: A switching device for a high-level valve in a well includes a hand handle with a lifting assembly on the hand handle. A switching assembly is located at the end of the lifting assembly opposite to the hand handle, and the switching assembly engages with the handle of a handle-type valve.

[0007] By adopting the above technical solution, a lifting component is set on the handheld lever to adjust the height of the switch component, so that the switch component can accurately engage with the handle of the handle-type valve, realizing remote opening and closing operation of the handle-type valve. This avoids the situation where the staff need to climb to a high place to manually close the valve, improves operating efficiency and reduces the contamination of the staff's clothing.

[0008] Preferably, the lifting assembly includes a drive unit disposed within the handgrip and a lifting rod with one end fixedly connected to the output end of the drive unit, and the lifting rod is slidably disposed within the handgrip.

[0009] By adopting the above technical solution, the driving component can drive the lifting rod to slide within the hand handle, thereby achieving flexible adjustment of the lifting rod height and thus flexible adjustment of the position of the switch assembly. This design allows the position of the switch assembly to be precisely adjusted according to actual needs, thus facilitating the operation of the handle-type valve at a high position in the well.

[0010] Preferably, the switch assembly includes a rotating shaft fixedly connected to one end of the lifting rod away from the hand handle, and a connecting rod rotatably connected to the other end of the rotating shaft. Both ends of the connecting rod are provided with locking rods on the side away from the lifting rod, and the two locking rods respectively form a locking engagement with both sides of the handle of the handle-type valve.

[0011] By adopting the above technical solution, one end of the rotating shaft in the switch assembly is fixedly connected to the lifting rod, and the other end is rotatably connected to the connecting rod, thereby driving the locking rod on the connecting rod to rotate. The locking rod forms a stable locking engagement with both sides of the handle of the handle-type valve, which can prevent slippage during the switching process. As the lifting rod moves upward, the locking rod can stably and effectively drive the handle of the handle-type valve to rotate, thereby realizing the valve switching operation. This design is not only convenient to operate, but also significantly improves the efficiency and stability of valve switching at high positions in the well.

[0012] Preferably, the connecting rod and the snap-fit ​​rod are detachably connected.

[0013] By adopting the above technical solution, the connecting rod and the snap-fit ​​rod are detachably connected, so that the snap-fit ​​rod can be replaced according to actual needs. When there are obstacles on the side wall of the well and the snap-fit ​​rod of the basic length cannot be snapped with the two sides of the handle of the handle-type valve, a longer snap-fit ​​rod can be replaced for opening and closing operation.

[0014] Preferably, a limiting groove is formed on the inner wall of the handheld lever along the length direction of the handheld lever, and a limiting block is fixedly connected to the lifting rod along the length direction of the lifting rod, and the limiting block and the limiting groove form an embedded sliding fit.

[0015] By adopting the above technical solution, the setting of the limiting groove and the limiting block can effectively limit the rotation of the lifting rod in the hand handle, ensuring that the lifting rod only makes stable linear sliding motion along the length direction of the hand handle. This design avoids the lifting rod from deflecting or getting stuck during the lifting process, thereby improving the operational stability and reliability of the device.

[0016] Preferably, the end of the lifting rod away from the hand handle is provided with a lighting element.

[0017] By adopting the above technical solution, a lighting element is installed at the end of the lifting rod away from the hand handle, which can provide illumination in the low-light environment of the well, allowing the staff to observe the position of the handle valve more clearly, thereby improving the accuracy of operation.

[0018] Preferably, the handheld handle is provided with a protective sleeve.

[0019] By adopting the above technical solution, the protective sleeve can effectively prevent the battery from being damaged by water in the humid environment of the well, ensuring a stable energy supply for the entire device. At the same time, the protective sleeve can also reduce wear on the surface of the handheld rod, thereby extending the service life of the entire device.

[0020] Preferably, the protective sleeve is provided with anti-slip protrusions.

[0021] By adopting the above technical solution, the anti-slip protrusions on the protective cover can increase the friction between the handheld lever and the operator's hand, thereby effectively preventing the handheld lever from falling off due to sweaty or slippery hands during operation. This design significantly improves the stability and safety of the device in actual use.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the handheld lever, lifting assembly, and switch assembly, the operator can remotely operate the handle-type valve at a high position in the manhole without climbing a ladder, which significantly improves the convenience and efficiency of operation. The setting of the limit groove and limit block can effectively limit the rotation of the lifting lever in the handheld lever, ensuring that the lifting lever only makes stable linear sliding movement along the length of the handheld lever. The switch assembly forms a snap-fit ​​with the handle of the handle-type valve through the snap-fit ​​rod, ensuring the stability and reliability of the switch operation. The connection between the connecting rod and the snap-fit ​​rod is detachable, so that the snap-fit ​​rod can be replaced according to actual needs. 2. An illumination element is installed at the end of the lifting rod away from the handheld rod, which can provide illumination in the low-light environment of the well, thereby improving the accuracy of operation. The protective cover can effectively prevent the battery from being damaged by water in the damp environment of the well, and can also reduce the wear on the surface of the handheld rod, thereby extending the service life of the entire device. The anti-slip protrusions on the protective cover can increase the friction between the handheld rod and the operator's hand, thereby effectively preventing the handheld rod from falling off during operation due to sweaty or slippery hands.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0026] This application discloses a switching device for a valve at a high position inside a well.

[0027] Reference Figure 1 and Figure 2 A switching device for a high-level valve in a well includes a hand lever 1, which is hollow and houses a battery 11 and a controller 12. The battery 11 and the controller 12 are electrically connected. A lifting assembly 2 is provided on the hand lever 1, and a lifting control button 13 electrically connected to the controller 12 is provided on the outer wall of the hand lever 1. In this embodiment, the lifting assembly 2 includes a drive component 21 disposed in the hand lever 1 and a lifting rod 22 slidably disposed in the hand lever 1. The drive component 21 is an electric telescopic rod, and one end of the lifting rod 22 is fixedly connected to the output shaft of the drive component 21 through a coupling. The lifting control button 13 includes three buttons: up, stop, and down, corresponding to three operating modes. The end of the lifting rod 22 facing away from the hand lever 1 is rotatably connected to the switch assembly 3, and the switch assembly 3 forms a snap-fit ​​engagement with the handle of the handle-type valve.

[0028] In practical use, the battery 11 inside the handheld lever 1 provides power to the entire device. The battery 11, controller 12, and lifting control button 13 are electrically connected, thereby enabling the lifting control button 13 to control the drive component 21 to work. At the same time, the lifting control button 13 has three buttons and corresponds to three operating modes, which further improves the accuracy of the height adjustment of the lifting lever 22. The drive component 21 can drive the lifting lever 22 to slide inside the handheld lever 1, realizing flexible adjustment of the height of the lifting lever 22. This allows the switch assembly 3, which is rotatably connected to the lifting lever 22, to accurately engage with the handle of the handle-type valve, realizing remote opening and closing of the handle-type valve, thus avoiding the situation where the staff needs to climb to a high place to manually close the valve.

[0029] Reference Figure 1 and Figure 2 The inner wall of the handheld lever 1 has a limiting groove 14 along its length, and the lifting rod 22 is fixedly connected to a limiting block 221 by welding along its length. The limiting block 221 and the limiting groove 14 form an embedded sliding fit. In this embodiment, there are two limiting grooves 14, which are symmetrically arranged about the handheld lever 1. There are also two limiting blocks 221 corresponding to the number and position of the limiting grooves 14. In actual use, the setting of the limiting grooves 14 and the limiting blocks 221 can effectively limit the rotation of the lifting rod 22 in the handheld lever 1, and prevent the lifting rod 22 from deflecting or getting stuck during the lifting process.

[0030] Reference Figure 1 and Figure 3 The switch assembly 3 includes a rotating shaft 31 fixedly connected to the end of the lifting rod 22 away from the hand handle 1 by welding. The other end of the rotating shaft 31 is rotatably connected to a connecting rod 32 via a bearing. Both ends of the connecting rod 32 away from the lifting rod 22 are detachably connected to a snap-fit ​​rod 33. The two snap-fit ​​rods 33 respectively form a snap-fit ​​engagement with the two sides of the handle of the handle-type valve. In this embodiment, the detachable connection between the connecting rod 32 and the snap-fit ​​rod 33 is a threaded connection.

[0031] In practical use, the connecting rod 32, which is rotatably connected to the rotating shaft 31, drives the locking rod 33 to rotate, so that the locking rod 33 forms a stable locking engagement with both sides of the handle of the handle-type valve, which can prevent slippage during the opening and closing process. As the lifting rod 22 moves upward, the locking rod 33 can stably and effectively drive the handle of the handle-type valve to rotate, thereby realizing the valve opening and closing operation. At the same time, the threaded connection between the connecting rod 32 and the locking rod 33 allows the locking rod 33 to be replaced according to actual needs. When there are obstacles on the side wall of the well, a longer locking rod 33 can be replaced for opening and closing operation.

[0032] Reference Figure 1 and 3The lifting rod 22 has a lighting element 4 at the end opposite to the hand handle 1, and the outer wall of the hand handle 1 has a lighting control button 15 electrically connected to the controller 12. In this embodiment, the lifting rod 22 is fixedly connected to an annular mounting block 41 by welding at the end opposite to the hand handle 1. The mounting block 41 has multiple equally spaced mounting slots 42, and each mounting slot 42 is embedded with an LED bead 421. The lighting control button 15 is a toggle switch and includes two operation modes: on and off. In actual use, the lighting element 4 can provide illumination in the well environment with insufficient light, allowing the operator to more clearly observe the position of the handle valve. At the same time, the lighting control button 15 electrically connected to the controller 12 is provided on the outer wall of the hand handle 1, making it convenient for the operator to turn the lighting function on or off at any time during operation.

[0033] Reference Figure 1 and Figure 4 The outer wall of the handheld lever 1 is fitted with a rubber protective sleeve 5, and the protective sleeve 5 has raised anti-slip protrusions 51 at the bottom of the handheld lever 1. In actual use, the protective sleeve 5 can effectively prevent the battery 11 from being damaged due to water ingress in the damp environment of the well. At the same time, the protective sleeve 5 can also reduce the wear on the surface of the handheld lever 1. The anti-slip protrusions 51 on the protective sleeve 5 can increase the friction between the handheld lever 1 and the operator's hand, thereby effectively preventing the handheld lever 1 from falling off due to sweaty or slippery hands during operation.

[0034] The implementation principle of this application embodiment is as follows: the battery 11 inside the handheld lever 1 provides power support to the device. The battery 11, controller 12, and lifting control button 13 are electrically connected, thereby enabling the lifting control button 13 to control the drive component 21 to work. The lifting control button 13 has three buttons and corresponds to three operating modes, further improving the accuracy of the height adjustment of the lifting lever 22. The drive component 21 drives the lifting lever 22 to slide within the handheld lever 1, realizing flexible adjustment of the lifting height, so that the switch assembly 3 and the valve handle can be accurately engaged. The embedded sliding cooperation of the limit groove 14 and the limit block 221 effectively limits the deflection of the lifting lever 22, ensuring the stability of the lifting; rotatably connected to the rotating shaft 3 The connecting rod 32 on the top drives the locking rods 33 on both sides to rotate synchronously. When the lifting rod 22 rises, it drives the valve handle to rotate to complete the opening and closing operation. At the same time, the connecting rod 32 and the locking rod 33 are threadedly connected, and the locking rods 33 of different lengths can be replaced according to actual needs. The lighting elements 4, which are evenly spaced around the end of the lifting rod 22, are controlled by the lighting control button 15, which is electrically connected to the controller 12, to provide multi-angle lighting for the dimly lit well. The rubber protective sleeve 5 with anti-slip protrusions 51 at the bottom not only prevents water from entering the hand handle 1 and damaging the battery 11, but also increases the friction to prevent slippage during operation. At the same time, the protective sleeve 5 can also reduce the wear on the surface of the hand handle 1, thereby extending the service life of the entire device.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
