A pressure water test device for hydrogeological engineering exploration

Abstract

This utility model discloses a pressure test device for hydrogeological engineering surveys, including a main body and a support mechanism located on one side of the main body. This support mechanism reduces the sagging caused by the device connecting to the hose through bottom support, ensuring the stability of the connection end. The support mechanism includes a side frame fixedly connected to one side of the foot pad. Water is introduced through an external hose when the valve body is opened. Water is introduced into the pressure test air chamber at one end of the water inlet pipe through a water meter and the valve body. After being pressurized in the pressure test air chamber, water is discharged through a drain pipe. This effectively reduces the sagging caused by the device connecting to the external hose during the assembly and use of pressure tests in hydrogeological engineering surveys. This also ensures that during long-term use, the connection end is not affected by external force accidental contact or impact force generated during water supply, thus reducing the shaking amplitude caused by the impact force. This improves the confidentiality of the connection and reduces the occurrence of water leakage after loosening.

Description

Technical Field

[0001] This utility model belongs to the field of hydrogeological exploration technology, specifically relating to a pressure test device for hydrogeological exploration. Background Technology

[0002] The water pressure test device is an indispensable tool in hydrogeological exploration. By measuring the permeability of rock mass and the degree of fracture development, it provides a scientific basis for engineering design. Its high precision and multi-functionality make it of great significance in fields such as geotechnical engineering, hydrogeology and nuclear energy.

[0003] Some existing water pressure testing devices used in hydrogeological engineering surveys need to be connected to a water supply hose during use to pressurize the incoming water before discharging it. During this process, due to the lack of a supporting structure at the connection point, the connection between the device and the pipe will sag due to gravity. As the usage time increases, the sag can easily lead to loosening and leakage at the connection between the device and the pipe due to accidental contact with external forces and the impact of the pipeline during water delivery, which is quite inconvenient. Utility Model Content

[0004] The technical problem this utility model aims to solve is to overcome existing defects and provide a water pressure testing device for hydrogeological engineering surveys. This addresses the issue mentioned in the background section where existing water pressure testing devices for hydrogeological engineering surveys require connection to a water supply hose during use. The introduced water is then pressurized and discharged. During this process, due to the lack of a supporting structure at the connection point, the connection between the device and the hose sags under gravity. With increasing usage time, accidental contact by external forces and the impact of pipeline forces during water delivery can easily cause the sagging part to loosen, leading to leaks and significant inconvenience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure test device for hydrogeological engineering exploration, comprising a main body and a support mechanism disposed on one side of the main body to reduce the sagging caused after the device is connected to the hose by bottom support, thereby ensuring the stability of the connection end. The support mechanism includes a side frame fixedly connected to one side of the foot pad. A first screw is threadedly connected to one side of the inside of the side frame. A slider is threadedly connected to the outer side of one end of the first screw. A sliding arm is slidably connected to the outer side of the slider. The foot pad and the side frame are slidably connected to the outer side of the sliding arm. A side block is fixedly connected to one side of the sliding arm. Several bottom columns are symmetrically arranged at the bottom of the inner side of the side block. A top frame is fixedly connected to the top of the side block. A second screw is threadedly connected to the inner side of the top frame. A support plate is rotatably connected to the outer side of the top end of the second screw. A fixing ring is fixedly connected to the outer side of the bottom end of the second screw.

[0006] Preferably, the main body includes a water pressure test air chamber, a drain pipe is fixedly connected to one side of the water pressure test air chamber, a water inlet pipe is fixedly connected to the other side of the water pressure test air chamber, a valve body is fixedly connected to one end of the water inlet pipe, a water meter is fixedly connected to one end of the valve body, a transfer pipe is fixedly connected to one side of the water meter, and a foot pad is fixedly connected to the bottom of the water pressure test air chamber.

[0007] Preferably, a support pad is fixedly connected to the top of the support piece, the support pad is made of rubber, and a second screw is rotatably connected to the inner side of the bottom of the support piece.

[0008] Preferably, a slide rod is fixedly connected to one side of the bottom of the tray, and two slide rods are symmetrically arranged. A top frame is slidably connected to the outside of the slide rod.

[0009] Preferably, a spring is movably connected to the outer side of the second screw, and the spring is located between the top frame and the fixing ring.

[0010] Preferably, a pinch pad is fixedly connected to the outside of the fixing ring, and the pinch pad is made of a flexible material.

[0011] Preferably, a ball bearing is rotatably connected to the inner side of the bottom end of the bottom post, and a side block is fixedly connected to the outer side of the bottom post.

[0012] Preferably, a slide bar is fixedly connected to the other side of the slide arm. Two slide bars are symmetrically arranged. The slide bars have a T-shaped structure, and a foot pad and a side frame are slidably connected to the outer side of the slide bar.

[0013] Compared with the prior art, this utility model provides a water pressure testing device for hydrogeological exploration, which has the following advantages:

[0014] 1. This utility model connects the drainage end device of the hydrogeological survey water pressure test to the drainage pipe by setting a support plate, and then connects the external hose to the adapter pipe. Based on the sag caused by gravity on the side block and adapter pipe after connection, the first screw is rotated counterclockwise to loosen it, thereby reducing the pressure of the outer wall of the slider pressing against the inner wall of the sliding arm and releasing the restriction on the position of the sliding arm. Then, the sliding arm is extended to the required length by sliding on the foot pad and inside the side frame. The first screw is rotated clockwise to tighten the slider, increasing the pressure of the outer wall of the slider pressing against the inner wall of the sliding arm, fixing the length position of the sliding arm. The pinch pad on the outer wall of the fixing ring is held, and the second screw is rotated inside the top frame. The height of the second screw is adjusted by raising and lowering it. In this manner, the support plate is adjusted so that its top support pad fully contacts the bottom of the connection end between the external hose and the adapter pipe, thus supporting it. The valve body is opened and water is introduced through the external hose. The water is introduced into the pressure test air chamber at one end of the water inlet pipe through the water meter and the valve body. After being pressurized in the pressure test air chamber, it is discharged through the drain pipe. This can effectively reduce the amount of sagging generated after the device is connected to the external hose during the assembly and use of pressure test in hydrogeological engineering surveys. This also ensures that during long-term use, the connection end is not affected by external force accidental contact or impact force generated during water supply, thus reducing the shaking amplitude caused by the impact force. This improves the confidentiality of the connection and reduces the occurrence of water leakage after loosening.

[0015] 2. By setting a sliding rod, this utility model can effectively ensure the stability of the position of the support plate during lifting and stress, and reduce the swing amplitude;

[0016] 3. This utility model provides support for the second screw inside the fixing ring by setting a spring and continuously supporting the top of the fixing ring with the spring, thereby effectively reducing the loosening of the second screw during long-term use.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

[0028] In this utility model, preferably, a slide rod 4 is fixedly connected to one side of the bottom of the support plate 209. Two slide rods 4 are symmetrically arranged.

[0030] In this utility model, preferably, a pinch pad 6 is fixedly connected to the outside of the fixing ring 210. The pinch pad 6 is made of flexible material, which can effectively improve the comfort of the person pinching and rotating during the process.

[0032] In this utility model, preferably, a slide bar 8 is fixedly connected to the other side of the slide arm 204. Two slide bars 8 are symmetrically arranged.

[0033] The working principle and usage process of this utility model are as follows: In use, connect the drainage end device of the hydrogeological survey water pressure test to the drainage pipe 102, and then connect the external hose to the adapter pipe 106. Based on the sag caused by gravity on the side block 205 and the adapter pipe 106 after connection, rotate counterclockwise and loosen the first screw 202 to reduce the pressure of the outer wall of the slider 203 pressing against the inner wall of the sliding arm 204, thereby releasing the restriction on the position of the sliding arm 204. Then, slide the sliding arm 204 to the required length on the inner side of the foot pad 107 and the side frame 201. Rotate the first screw 202 clockwise to tighten the slider 203, increasing the pressure of the outer wall of the slider 203 pressing against the inner wall of the sliding arm 204, fixing the length position of the sliding arm 204. Pinch the pinch pad 6 on the outer wall of the fixing ring 210, and rotate the second screw 6 within the top frame 207. The screw 208, by raising and lowering the height of the second screw 208, adjusts the support plate 209 to the height where its top support pad 3 fully contacts the bottom of the connection end between the external hose and the adapter pipe 106, thus supporting it. The valve body 104 is opened and water is introduced through the external hose. The water is introduced through the water meter 105 and the valve body 104 into the pressure test air chamber 101 at one end of the water inlet pipe 103. After being pressurized by the pressure test air chamber 101, it is discharged through the drain pipe 102. This can effectively reduce the amount of sagging generated after the device is connected to the external hose during the assembly and use of the pressure test in hydrological engineering geological exploration. This ensures that during long-term use, the connection end is not affected by external force accidental contact or the impact force generated during water supply, which will cause shaking amplitude, improve the confidentiality of the connection, and reduce the occurrence of water leakage after loosening.
