Description

Technical Field

[0001] This application relates to the field of cutting well drilling rig technology, specifically to a water system for a cutting groove well drilling rig. Background Technology

[0002] A cutting groove riser is a type of mechanical equipment used to excavate large tunnels in underground mines. A cutting groove riser consists of drill bits, a cutting head, a guiding system, a propulsion system, a support system, a hydraulic system, and a slag removal system. In existing cutting groove risers, to achieve effective slag removal, water pipes are installed, connected to external water pumps, for water-based slag removal and flushing.

[0003] However, when this type of well-cutting drill is used on-site, workers need to connect a separate water pump outside the site, which makes it more troublesome to use the slag removal and flushing functions of the well-cutting drill.

[0004] Therefore, there is room for further improvement in existing slotted well drilling rigs. Utility Model Content

[0005] In view of this, and addressing the technical problem that the water system structure of the existing slotted well drilling rig requires an external water pump and the slag removal and flushing functions are cumbersome, this application provides a water system for a slotted well drilling rig that enables the slag removal and flushing functions to be used without an external water pump, thus simplifying the process of using the slag removal and flushing functions.

[0006] This application provides a water system for a cutting groove well drilling rig, including: Water inlet connector, used to connect to an external water source; The cleaning module, connected to the water inlet connector, is used to provide cleaning water; The rinsing module, connected to the water inlet connector and in parallel with the cleaning module, is used to provide rinsing water; The first shut-off valve is connected in series at the outlet end of the inlet connector; The second shut-off valve is connected in series at the water inlet of the cleaning module; A water pump is connected in series between the first shut-off valve and the flushing module, and in parallel with the cleaning module.

[0007] Compared with the prior art, the cutting groove riser water system of this application includes a flushing module and a cleaning module connected in parallel with the outlet of the inlet connector. The liquid flowing out of the inlet connector can be divided into two water paths, flowing into the cleaning module and the flushing module respectively. The flushing module and the cleaning module each discharge liquids at different pressures to act on corresponding components, fulfilling the different water pressure cleaning requirements of different components. This application includes two shut-off valves. The first shut-off valve is directly connected to the outlet of the inlet connector, and its outlet is simultaneously connected to both the flushing module and the cleaning module. The first shut-off valve can control the water discharge of both the flushing module and the cleaning module, acting as a master switch. The second shut-off valve is connected in series at the inlet of the cleaning module, allowing independent control of the water discharge from the cleaning module. Notably, this application includes a water pump between the flushing module and the first shut-off valve. The water pump pressurizes the liquid, ensuring that the liquid flowing out of the flushing module has a higher pressure to meet the flushing water requirements. Therefore, in this application, by setting up two parallel water channels and connecting a water pump in series in one of the water channels, the needs for atmospheric pressure cleaning water and pressurized flushing water can be met. The flushing water needs can be met without the need for an external water pump, so as to assist in completing the water needs for the slag removal and flushing functions of the cutting groove riser, simplify the use of the slag removal and flushing functions, and improve the ease of use of the cutting groove riser.

[0008] Preferred options also include: External connector for connecting an external water pump; The third shut-off valve is connected in series between the external connector and the flushing module; An electrically controlled shut-off valve is connected in series between the water pump and the flushing module; The third shut-off valve is connected in parallel with the flushing module at the output end of the electrically controlled shut-off valve.

[0009] Preferred options also include: The drain outlet is connected in parallel with the flushing module and the cleaning module to the output end of the first shut-off valve. A safety valve is connected in series between the first shut-off valve and the drain outlet.

[0010] Preferred options also include: The radiator has its input end connected to the output end of the first shut-off valve, and its output end is simultaneously connected to the safety valve, the water pump, and the second shut-off valve.

[0011] Preferably, the radiator includes an oil inlet end and an oil outlet end, with the oil inlet end connected to the oil tank and the oil outlet end connected to the return oil filter.

[0012] Preferred options also include: The first filter is connected in series between the inlet connector and the first shut-off valve; The second filter is connected in series at the inlet of the flushing module.

[0013] Preferred options also include: A pressure reducing valve is connected in series between the first shut-off valve and the radiator.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0022] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 2 illustrate.

[0023] This application provides a water system for a cutting groove riser (hereinafter referred to as the water system). The water system is integrated on the cutting groove riser. It can meet the water needs of the cutting groove riser for slag removal and flushing functions without connecting to an external water pump, only requiring an external water source. This simplifies the process of using the slag removal and flushing functions and improves the ease of use of the cutting groove riser.

[0024] Specifically, such as Figures 1 to 2 As shown, the water system includes an inlet connector 1, a cleaning module 2, a rinsing module 3, and a drain outlet 10. The inlet end of the inlet connector 1 is used to connect to an external water source, and the outlet end of the inlet connector 1 is connected to three water channels, namely the first water channel, the second water channel, and the third water channel. The first, second, and third water channels are arranged in parallel, meaning that the liquid at the outlet end of the inlet connector 1 can simultaneously flow into the first, second, and third water channels; wherein, as... Figure 1 , Figure 2 As shown, the first water path is connected to the cleaning module 2 to provide cleaning water; the second water path is connected to the rinsing module 3 to provide rinsing water; and the third water path is connected to the drain outlet 10 to discharge excess liquid from the water system.

[0025] Among them, such as Figure 2 As shown, the water system also includes a first shut-off valve 4, a second shut-off valve 5, and a water pump 6. The first shut-off valve 4 is connected in series at the outlet end of the inlet connector 1. At the same time, the outlet end of the first shut-off valve 4 is also the inlet end of the first water path, the second water path, and the third water path. The first shut-off valve 4 acts as the main switch in the water system and can control the connection or disconnection of the three water paths at the same time.

[0026] like Figure 2 As shown, the second shut-off valve 5 is connected in series in the first water circuit and is connected in series at the water inlet of the cleaning module 2. Without affecting the opening and closing of the second and third water circuits, the second shut-off valve 5 can independently control the opening and closing of the water circuit of the cleaning module 2, thereby improving the flexibility of the water circuit system.

[0027] like Figure 2 As shown, water pump 6 is connected in series in the second water path and is connected in series at the inlet of flushing module 3. At the same time, water pump 6 is connected in parallel with cleaning module 2 and drain outlet 10. That is, water pump 6 only controls the liquid pressure of the second water path to pressurize the water output of flushing module 3, so that the liquid flowing out of flushing module 3 has a high pressure to meet the flushing water requirements. Therefore, the water path system of this application sets at least two parallel water paths, one for normal pressure water output and the other for the series water pump 6 to meet the pressurized flushing water requirements. The flushing water requirements can be met without the need for an external water pump, so as to assist in meeting the water requirements of the slag removal and flushing functions of the cutting groove riser, simplify the use of slag removal and flushing functions, and improve the ease of use of the cutting groove riser.

[0028] The flushing module 3 includes a drill bit flushing module 3, a chute flushing module 3, and a seal flushing module 3 connected in parallel. This means the flushing module 3 can simultaneously flush the drill bit, chute, and seals of the cutting groove well drilling rig. Of course, other flushing modules 3 can also be set up to flush other modules that require flushing; there are no restrictions here. The cleaning module 2 includes a drill pipe thread cleaning module 2. Of course, other cleaning modules can also be set up to clean other modules that require flushing; there are no restrictions here.

[0029] Further description of the first waterway, such as Figure 2 As shown, a solenoid valve 17 is also connected in series in the first water circuit. The solenoid valve 17 is connected in series between the second shut-off valve 5 and the flushing module 3. The solenoid valve 17 and the second shut-off valve 5 are used in series to realize the automatic on-off control of the first water circuit and improve the control flexibility of the first water circuit.

[0030] Further description of the second waterway, such as Figure 2 As shown, the second water circuit also includes an electrically controlled shut-off valve 9, a pressure sensor 18, and a second filter 15 connected in series. The water pump 6, pressure sensor 18, electrically controlled shut-off valve 9, second filter 15, and flushing module 3 are connected in series in sequence. The electrically controlled shut-off valve 9 has an electrical control function, which can realize automatic and remote control of the connection of the second water circuit. The pressure sensor 18 can detect the outlet pressure value of the water pump 6 and is connected to the pressure gauge 19. The pressure gauge 19 can display the outlet pressure detected by the pressure sensor 18 in real time, so that the user can know the flushing water pressure value in time, and can adjust the water pump 6 in time to meet the flushing water demand and improve the ease of use. The second filter 15 is located at the inlet of the flushing module 3 and can filter the liquid entering the flushing module 3 to prevent large impurities from entering the flushing module 3 and affecting the flushing effect.

[0031] Further description of the third waterway, such as Figure 2 As shown, a safety valve 11 is also connected in series in the third water circuit. The safety valve 11 is connected in series at the inlet end of the drain outlet 10. The safety valve 11 acts as a safety protection device to prevent the water circuit system from malfunctioning due to excessive pressure.

[0032] Based on any of the above embodiments, the water system will be further described; such as Figure 1 , Figure 2 As shown, the water system also includes an inlet water path, which is connected in series with the outlet end of the inlet connector 1. The inlet water path is the main water path, and the first water path, the second water path, and the third water path are connected in parallel to the outlet end of the inlet water path.

[0033] Specifically, the first shut-off valve 4 is connected in series in the water inlet circuit. The water inlet circuit also connects the first filter 14, the pressure reducing valve 16, and the radiator 12 in series. The first filter 14, the first shut-off valve 4, the pressure reducing valve 16, and the radiator 12 are connected in series in the direction of liquid flow. The first filter 14 is used to filter the liquid entering the first shut-off valve 4 to prevent large impurities from entering the first shut-off valve 4 and affecting the water supply of the water circuit system. The pressure reducing valve 16 is used to automatically stabilize the pressure of the liquid flowing into the water inlet circuit to prevent it from affecting downstream components.

[0034] The radiator 12 provides liquid cooling to the hydraulic system of the cutting groove riser via a water system. The outlet of the radiator 12 is simultaneously connected to the inlets of the first, second, and third water channels. Furthermore, the radiator 12 includes an oil inlet and an oil outlet. The oil inlet is connected to the oil tank, and the oil outlet is connected to the return oil filter 13. The oil circulates repeatedly between the oil tank, the radiator 12, and the return oil filter 13 to cool the oil in the tank, ensuring the cooling of the hydraulic system of the cutting groove riser. Of course, the water channels and oil channels of the radiator 12 are independent of each other, and they achieve cooling of the hydraulic system through heat exchange.

[0035] Based on any of the above embodiments, the water system will be further described; such as Figure 1 , Figure 2 As shown, the water system also includes a fourth water path, which includes an external connector 7 and a third shut-off valve 8. The external connector 7 and the third shut-off valve 8 are connected in series. The external connector 7 is used to connect an external water pump. The inlet of the fourth water path is located between the electrically controlled shut-off valve 9 and the second filter 15, that is, the fourth water path and the second filter 15 are connected in parallel at the output end of the electrically controlled shut-off valve 9. In this embodiment, by setting up the fourth water path, an external water pump can be connected to pressurize the flushing water without using the water pump 6 connected internally in the second water path, thereby improving the flexibility of the water system. The third shut-off valve 8 can independently control the opening and closing of the fourth water path.

[0036] The water system of this application has the following usage modes: When using the drilling rig's built-in water pump 6, the first shut-off valve 4 and the second shut-off valve 5 are open, and the third shut-off valve 8 is closed. External water, after passing through the first filter 14, the first shut-off valve 4, the pressure reducing valve 16, and the radiator 12, is divided into at least two paths before reaching the inlet of the water pump 6: a first water path and a second water path. The first water path supplies water to the cleaning module 2, and the second water path supplies water to the flushing module 3. The first and second water paths can be connected individually or simultaneously through the cooperation of the second shut-off valve 5, the solenoid valve 17, and the electrically controlled shut-off valve 9.

[0037] When the water pump 6 is not started, the solenoid valve 17 is open and the electrically controlled shut-off valve 9 is closed, which is the start of the cleaning module 2 to provide cleaning water; when the water pump 6 is started, the solenoid valve 17 is closed and the electrically controlled shut-off valve 9 is opened, which is the start of the flushing module 3 to provide flushing water.

[0038] When using an external water pump, since the water pump 6 is not started, the solenoid valve 17 is open and the electrically controlled shut-off valve 9 is closed; after opening the third shut-off valve 8, the external water pump can be started to flush the drill bit, chute and seals.

[0039] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.

[0040] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
