Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, specifically relating to a high-pressure water jet breakdown testing device. Background Technology

[0002] High-pressure water jetting is a technology that uses a high-pressure water generator to pressurize water and then ejects it from a jetting device with a small aperture, forming a highly energetic jet. High-pressure water jetting has a wide range of applications; relatively low-pressure jets can be used for cleaning and rinsing, while high-pressure jets are used for cutting. In tunnel boring machines (TBMs), high-pressure water jetting can be used for cutterhead cutting in TBMs and other tunnel boring machines, as well as for crushing large-diameter debris, especially hard rocks. Conventional high-pressure water jetting uses a special cutting platform to prevent damage to the equipment. However, the internal space of a TBM is relatively small, making it difficult to install a high-pressure water jet cutting platform. Therefore, using high-pressure water jetting to crush large-diameter debris inside a TBM carries the risk of accidental damage to the TBM, especially in the confined space of the slurry circulation system of a slurry-balanced TBM. There is a risk that the high-pressure water jet may penetrate components of the slurry circulation system, and this risk is difficult to detect and predict, posing a significant safety hazard. Utility Model Content

[0003] The purpose of this invention is to address the risks of high-pressure water jet devices damaging equipment components in confined spaces such as the circulation system of slurry shield tunneling machines, the difficulty in detecting damage caused by high-pressure jets, and the significant safety hazards. This invention proposes a high-pressure water jet breakdown detection device. This device protects equipment from damage by high-pressure water jets and also issues an alarm upon detection of damage, allowing users to promptly inspect and repair the equipment, thus protecting its health and eliminating safety hazards.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-pressure water jet breakdown detection device includes a container equipped with a high-pressure water jet nozzle; it also includes an internal part, an external part, and a control system; the internal part includes a base, an impact alloy seat, and a pressure sensor; the base has a through groove inside, and the impact alloy seat and the pressure sensor are respectively inserted into the through groove from both ends of the base; the base is detachably passed through and fixed to the container, such that the impact alloy seat is located inside the container and directly facing the high-pressure water jet nozzle; the rear part of the pressure sensor extends from the rear of the base and is located outside the container; the rear part of the pressure sensor is provided with a signal connection pin; the signal connection pin is connected to the external part; the external part is connected to the control system; the control system is equipped with an alarm.

[0006] The container is equipped with a high-pressure water jet nozzle. This container serves as a sealed space for the slurry circulation system of the slurry balance shield machine. Within this space, the high-pressure water jet is used to break up rocks and blockages in the slurry. The front half of the base extends into the container equipped with the high-pressure water jet nozzle, placing the impact alloy seat inside the container and directly facing the high-pressure water jet nozzle. When the high-pressure water jet strikes directly, the impact alloy seat counteracts the impact force, preventing damage to the equipment. The impact alloy seat is made of a high-strength alloy, such as high-manganese steel, possessing a certain degree of hardness and capable of withstanding certain forces. The device is designed to withstand the impact of high-pressure water jets for extended periods, protecting the equipment. The rear half of the base extends outside the container equipment, while the front half of the pressure sensor extends into the through-slot of the base, with the rear half extending out of the container equipment along with the base. It is connected to the external mounting via a signal connector. When the impact alloy base is punctured, the water flow exerts pressure on the pressure sensor within the through-slot, triggering an alarm in the control system via the signal connector and the external mounting. The pressure sensor is also connected to a power cord, which is connected to a power source at the construction site or on the equipment to provide power to the pressure sensor.

[0007] As a further technical improvement, the base is provided with an annular sealing groove on the side where it connects to the impact alloy seat; a sealing ring is provided inside the sealing groove; the impact alloy seat has a stepped portion, so that after the impact alloy seat is inserted into the base, the stepped portion and the sealing ring are sealed together. The stepped portion of the impact alloy seat also has an annular groove corresponding to the sealing groove. After the impact alloy seat is installed on the base, the annular groove and the sealing groove clamp the sealing ring, which plays a sealing role and prevents water from entering the through groove from the connection position between the base and the impact alloy seat.

[0008] As a further technical improvement, a fixing seat is provided on the outside of the base; the fixing seat is provided with screw holes. Bolts are used to install and fix the fixing seat and the base to the inner wall of the container equipment through the screw holes. At this time, the side wall of the container equipment also needs to be drilled.

[0009] As a further technical improvement, a sealing gasket is provided between the mounting base and the inner wall of the container. The sealing gasket is used to seal the space between the mounting base and the inner wall of the container to prevent water from overflowing.

[0010] As a further technical improvement, one end of the outer casing is provided with a connecting groove and the other end with a signal line; a signal socket is provided in the connecting groove; the signal socket corresponds and matches with the signal connector; the signal line is connected to the control system. The connection between the signal socket and the signal line allows the detection signal to be transmitted to the control system via the signal line after the signal connector is inserted into the signal socket.

[0011] As a further technical improvement, the impact alloy seat and the base are connected by threads; the impact alloy seat has flat grooves on both sides. The flat grooves are used to clamp the impact alloy seat and screw it into the base.

[0012] As a further technical improvement, a reinforcing component is provided between the base and the pressure sensor. The reinforcing component is used to tighten the base and the pressure sensor; the reinforcing component is divided into two parts, one part is connected to the base, and the other part is connected to the outside of the pressure sensor. The two parts of the reinforcing component can be connected to each other by means of fastening, threaded connection, etc. After connection, the pressure sensor and the base are tightly connected and not easy to loosen.

[0013] The above-described method for using the high-pressure water jet breakdown detection device:

[0014] The device is installed on a container with a built-in high-pressure water jet nozzle. The base is inserted into the container, and the impact alloy seat faces the high-pressure water jet nozzle. The signal connection pin of the pressure sensor is inserted into the signal socket of the external mounting. When the high-pressure water jet nozzle is working, it sprays a high-pressure water jet, which disperses or breaks hard objects inside the container, such as rocks in the enclosed space of the circulation system of a slurry balance shield tunneling machine. When there is no object blocking the high-pressure water jet or the high-pressure water jet passes through an object, it will directly hit the impact alloy seat. Because the impact alloy seat is hard, it can withstand part of the impact force of the high-pressure water jet, protecting the container from damage. When the impact alloy seat is punctured, water flows into the through groove of the base and applies a certain pressure to the pressure sensor. The pressure sensor transmits the detected pressure signal to the control system through the signal connection pin and signal line. The alarm of the control system sounds, and maintenance personnel perform equipment maintenance, replace the impact alloy seat, and the equipment can be restored to normal operation.

[0015] The technical solution of this utility model has the following beneficial effects:

[0016] 1. This utility model uses an impact alloy seat to withstand the impact force of high-pressure water jets, preventing the high-pressure water jets from directly hitting the shield machine's slurry circulation system and other operating equipment, thus protecting the equipment from damage and ensuring its healthy operation.

[0017] 2. This utility model, through a pressure sensor installed in the base, can detect when the impact alloy seat is punctured by a high-pressure water jet and issue an alarm to remind staff to carry out equipment maintenance. After eliminating the possible fault and replacing the impact alloy seat, the equipment can be restored to normal use, thus eliminating the safety hazard of the equipment being punctured by a high-pressure water jet.

[0018] 3. The internal and external parts of this utility model device are connected by a plug-in connection, which allows the external part to transmit the signal detected by the pressure sensor in the internal part to the control system. It is simple and convenient to use and operate, and it is easy to replace and repair when the internal or external part fails, so that all parts of the device do not have to be replaced. This saves costs to a certain extent and increases the flexibility of the device. Attached Figure Description
