A fracturing device hole pressure detection device

Abstract

This utility model discloses a fracturing tool borehole pressure detection device, including a tip, which is connected to the fracturing tool via a screw. A pressure plate is provided on the outer side of the tip, a connecting column is provided on the inner side of the pressure plate, a pressure sensor is provided on the inner side of the connecting column, a mounting plate is provided on one side of the pressure sensor, and a mounting plate locking device is provided on one side of the mounting plate. By setting the pressure plate on the arc-shaped surface of the fracturing tool tip and making it directly contact the built-in pressure sensor through the connecting column, the pressure exerted by the fracturing tool tip on the borehole wall can be sensed and measured most directly and accurately, providing a reliable basis for the operator to install the borehole. The mounting plate locking device, consisting of a "rotating plate-locking plate-hand push rod," enables quick and stable locking and convenient disassembly of the pressure sensor. Simply push the hand push rod to rotate the locking plate to lock or unlock, making the operation extremely simple.

Description

Technical Field

[0001] This utility model belongs to the field of fracturing device technology, specifically relating to a fracturing device hole pressure detection device. Background Technology

[0002] Pre-splitting blasting or contour-controlled blasting technology is widely used in engineering fields such as mining, geological exploration, tunneling, and building demolition. The fracturing device is a key component for achieving controlled fracturing. Its working principle typically involves inserting the fracturing device into a pre-drilled borehole, where internal pressure (such as hydraulic or chemical expansion force) acts on the borehole wall, causing the rock or concrete to fracture in a predetermined direction.

[0003] Existing technologies lack a device for detecting the loading pressure of fracturing devices. Whether the fracturing device encounters obstacles during installation into the hole (such as the front end of the fracturing device being blocked and unable to be installed in place) depends entirely on the experience of the installer. Therefore, it is necessary to develop a device that can directly and reliably detect the loading pressure of fracturing devices. Utility Model Content

[0004] The purpose of this invention is to provide a device for detecting the pressure of a fracturing device in the borehole, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure detection device for a fracturing device, comprising a tip, the tip being connected to the fracturing device via a screw, a pressure plate being provided on the outer side of the tip, a connecting column being provided on the inner side of the pressure plate, a pressure sensor being provided on the inner side of the connecting column, a mounting plate being provided on one side of the pressure sensor, and a mounting plate locking device being provided on one side of the mounting plate.

[0006] Preferably, a pressure sensor mounting hole is provided on the inner side of the tip, and the pressure sensor is inserted into the pressure sensor mounting hole.

[0007] Preferably, the mounting plate locking device includes a rotating plate, a locking plate, and a push rod. The rotating plate is rotatably disposed on one side of the pressure sensor mounting hole, and the locking plate and the push rod are respectively disposed at both ends of the rotating plate.

[0008] Preferably, a perforated partition is provided on one side of the tip, and a screw connection hole is provided in the middle of the perforated partition, with the screw disposed in the screw connection hole.

[0009] Preferably, a baffle is provided on one side of the tip.

[0010] Preferably, the edge of the baffle is provided with a notch, and the tip is provided with a locking protrusion, which is adapted to the notch.

[0011] The technical effects and advantages of this utility model are as follows: By setting a pressure plate on the outer arc surface of the fracturing tip and making it directly contact the built-in pressure sensor through the connecting column, the pressure exerted by the fracturing tip on the borehole wall can be sensed and measured most directly and realistically, providing a reliable basis for workers to install the borehole.

[0012] The mounting plate locking device, consisting of a rotating plate, a locking plate, and a push rod, enables the pressure sensor to be quickly and securely locked and easily disassembled. Simply push the push rod to rotate the locking plate to lock or unlock, making the operation extremely simple.

[0013] To address the potential sealing issues caused by the perforated partition, a baffle structure was specially designed. By utilizing the notch on the edge of the baffle and the snap protrusion on the tip, the baffle can be quickly installed and reliably sealed through a simple "align-press-rotate" operation.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] This utility model provides, for example Figure 1-6 The device shown is a pressure detection device for a fracturing device, including a tip 2, which is conical in shape. A perforated partition 5 is provided on one side of the tip 2, and a screw connection hole 6 is provided in the middle of the perforated partition 5. A screw 3 is provided at one end of the fracturing device 1, and the screw 3 is screwed into the screw connection hole 6.

[0023] A notch is formed on the outer arc-shaped surface of the tip 2, and a pressure plate 4 is set on the notch. A connecting post 10 is set on the inner side of the pressure plate 4. The connecting post 10 slides through the tip 2. A pressure sensor mounting hole is formed on the inner side of the tip 2. The pressure sensor 11 is inserted into the pressure sensor mounting hole. The pressure sensor 11 is set on the inner side of the connecting post 10. When the pressure plate 4 is pressed, pressure is generated on the pressure sensor 11 through the connecting post 10, thereby performing pressure detection. The detection result can be transmitted through wired or wireless means.

[0024] As an embodiment of this application, the following method for fixing the pressure sensor 11 is provided: a mounting plate locking device is provided on one side of the mounting plate 12. The mounting plate locking device includes a rotating plate 13, a locking plate 14, and a push rod 15. The rotating plate 13 is rotatably disposed on one side of the pressure sensor mounting hole. The locking plate 14 and the push rod 15 are respectively disposed at both ends of the rotating plate 13. By pushing the push rod 15, the locking plate 14 is rotated. When the locking plate 14 rotates to one side of the mounting plate 12, it blocks the mounting plate, thereby fixing the pressure sensor 11. Because the pressure sensor 11 will be greatly affected during the subsequent explosion process, this quick-release method is designed to facilitate the disassembly, assembly, and maintenance of the pressure sensor 11.

[0025] Since a perforated partition 5 is provided on one side of the tip 2, the perforation facilitates the disassembly and assembly of internal components, but also reduces the sealing. Therefore, a baffle 7 is provided on one side of the tip 2. The edge of the baffle 7 is provided with a notch 8, and a locking protrusion 9 is provided on the tip 2. The locking protrusion 9 is adapted to the notch 8. When installing the baffle 7, the locking protrusion 9 and the notch 8 are aligned, and the baffle 7 is pressed in and rotated to make the locking protrusion 9 and the notch 8 misaligned.

[0026] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
