Description

Technical Field

[0001] The utility model relates to the technical field of water pressure tests, in particular to a simple water pressure test device. Background Technique

[0002] The water pressure test is an in-situ test that uses high pressure to inject water into a borehole and calculates the water absorption of the rock mass to understand the development of rock mass fissures and permeability. The water pressure test uses special water-stop equipment to isolate a certain length of the borehole test section, and then injects water into this section of the borehole with a fixed water head. The water penetrates into the rock mass through the fissures around the borehole wall, and finally the penetrated water volume will tend to a stable value.

[0003] For example, a water pressure test device for hydrogeological engineering geological exploration with the application number CN202122245398.3, which relates to the field of water pressure test devices for hydrogeological engineering geological exploration. The utility model includes an external water source device, a pre-test device, a water pressure test device, a telescopic support and an auxiliary device. One end of the first pipeline is connected to the outer surface of the water pump, the upper surfaces of the four water pressure pipelines are all connected to the lower surface of the tube barrel, the lower surfaces of the four cylinders are all connected to the upper surface of the bearing plate, the upper surface of the driving motor is connected to the lower surface of the tube barrel, a rotating shaft is arranged on the lower surface of the driving motor, the upper surface of the main shaft is connected to the lower surface of the rotating shaft, and the upper surface of the drill bit is connected to the lower surface of the main shaft. For the water pressure test device for hydrogeological engineering geological exploration of the utility model, the cylinder lifts to drive the piston to move up and down. The water injection cylinder is connected to the water tank through the water inlet pipeline. The piston compresses the internal space of the water injection cylinder, causing the liquid water to be pressed out from the water outlet pipeline, and can initially conduct a water pressure pre-test on the borehole, so as to use the water pump to increase the pressure step by step for the water pressure test device. However, the water pipes inside this simple water pressure test device are directly exposed to the outside. When the environmental temperature is too high, the pressure of the water pressure test is relatively inaccurate, and the calculated pressure of the water pressure test is large, and the pressure increase time is long. At the same time, the size of the pipe diameter cannot be adjusted, and the adaptation rate is low. Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a simple water pressure test device is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a simple water pressure test device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A simple water pressure test device, including a support column and a pressure gauge. The top of the support column is fixedly connected with a pressure gauge, and a connection block is arranged on one side of the support column. One side of the connection block is movably connected with an anti-corrosion water pipe, and a sun protection mechanism is arranged outside the anti-corrosion water pipe, and a diameter adjustment mechanism is arranged outside the sun protection mechanism. The bottom of the support column is fixedly connected with a water collecting tank.

[0006] Preferably, the sunscreen mechanism includes a radiation protection layer movably connected to the outside of the anti-corrosion water pipe, and a heat insulation board is arranged on the outside of the radiation protection layer, and a fastening ring is arranged on the outside of the heat insulation board.

[0007] Preferably, the caliber adjusting mechanism includes a fixing frame fixedly connected to the top of the water collecting tank, and an upper end movable plate is movably connected inside the fixing frame. A fixing plate is fixedly connected to one side of the fixing frame, and two-side movable plates are rotatably connected to one side of the fixing frame. An adjusting port is movably connected inside the upper end movable plate.

[0008] Preferably, a connecting plate is fixedly connected to one side of the support column, and a pressure pump is fixedly connected to one side of the connecting plate.

[0009] Preferably, a rotating shaft is fixedly connected to the top of the pressure pump, and the top end of the rotating shaft is rotatably connected to a pressure pump handle.

[0010] Preferably, one end of the pressure pump handle is rotatably connected to a pressure rod, and a water suction nozzle is arranged at the bottom of the pressure pump. A water collecting tank is arranged outside the water suction nozzle.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. Through the settings of the sunscreen mechanism and the caliber adjusting mechanism, the present utility model protects the anti-corrosion water pipe, avoiding the situation that when the environmental temperature is too high and the sun shines directly on the surface of the anti-corrosion water pipe, a small amount of gas contained in the water in the anti-corrosion water pipe will expand, affecting the result of the water pressure test. The radiation protection layer prevents the sun from shining directly and causing the anti-corrosion water pipe to age. The heat insulation layer isolates the anti-corrosion water pipe from the external high temperature, avoiding too high temperature. In the traditional device, the water pipe inside is directly exposed to the outside. When the environmental temperature is too high, the pressure of the water pressure test is relatively inaccurate, and the calculated pressure of the water pressure test is large, and the pressure increasing time is long. At the same time, the size of the pipe diameter cannot be adjusted, and the adaptation rate is low. The added caliber adjusting mechanism of the present utility model adjusts the width between the upper end movable plate and the two-side movable plates by pulling the fixing plate, thereby squeezing the anti-corrosion water pipe, adjusting the width of the anti-corrosion water pipe, and controlling the flow rate of the water flow inside the anti-corrosion water pipe, avoiding large pipeline diameter and water filling load, and reducing the requirements for the load on the structure and the bearing capacity of the foundation by changing the width of the anti-corrosion water pipe, facilitating the device to conduct tests in different environments;

[0013] 2. Through the settings of the anti-corrosion water pipe and the pressure pump handle, the anti-corrosion layer inside the anti-corrosion water pipe can prevent the inner surface of the pipe from being corroded when corrosive liquid passes through the anti-corrosion water pipe during water pressure measurement, and at the same time avoid rusting inside the pipe, reducing the frictional resistance of the pipeline and increasing the liquid delivery volume. A protective layer is arranged on the outside of the pressure pump handle, and the protective layer is made of sponge material, avoiding direct contact between the hand and the pressure pump handle, playing a role in protecting the palm, and at the same time preventing the pressure pump handle from slipping and affecting the extraction of the water source inside the water collecting tank.

One side of the connection block 3 is movably connected with an anti-corrosion water pipe 4. An anti-corrosion water pipe 4 is arranged outside the anti-corrosion water pipe 4, and a caliber adjustment mechanism 6 is arranged outside the sun protection mechanism 5. The bottom of the support column 1 is fixedly connected with a water collection tank 13. The connection block 3 connects the support column 1 with the pressure pump 8. A threaded hole is arranged inside the connection block 3 to connect the anti-corrosion water pipe 4 with the support column 1. The sun protection mechanism 5 plays a role in protecting the anti-corrosion water pipe 4.

[0021] As Figures 3 - 4As shown in the figure, the sunscreen mechanism 5 includes a radiation protection layer 501 movably connected to the outside of the anti-corrosion water pipe 4, and a heat insulation plate 502 is arranged on the outside of the radiation protection layer 501, and a fastening ring 503 is arranged on the outside of the heat insulation plate 502. The radiation protection layer 501 and the heat insulation plate 502 are an integrated mechanism, which respectively play the role of preventing direct sunlight and isolating high temperature for the anti-corrosion water pipe 4. Fastening rings 503 are arranged at both the upper and lower ends of the heat insulation plate 502, and the fastening rings 503 connect the anti-corrosion water pipe 4 with the radiation protection layer 501 and the heat insulation plate 502.

[0022] Furthermore, the aperture adjusting mechanism 6 includes a fixed frame 601 fixedly connected to the top of the water collecting tank 13, and an upper end movable plate 602 is movably connected inside the fixed frame 601. A fixed plate 603 is fixedly connected to one side of the fixed frame 601, and a two-sided movable plate 604 is rotatably connected to one side of the fixed frame 601. An adjusting port 605 is movably connected inside the upper end movable plate 602. An activity port is arranged inside the fixed frame 601, and the upper end movable plate 602 moves inside the activity port. The two-sided movable plates 604 are symmetrically distributed with respect to the upper end movable plate 602. The two sides of the upper end movable plate 602 drive the two-sided movable plates 604 to rotate on the fixed frame 601 to clamp the anti-corrosion water pipe 4, thereby adjusting the size of the aperture of the anti-corrosion water pipe 4 and increasing the applicable range of the device.

[0023] Furthermore, a connecting plate 7 is fixedly connected to one side of the support column 1, and a pressure pump 8 is fixedly connected to one side of the connecting plate 7. A rotating shaft 9 is fixedly connected to the top of the pressure pump 8, and the top end of the rotating shaft 9 is rotatably connected to a pressure pump handle 10. The inside of the connecting plate 7 is a hollow structure, so that the liquid flows through the pressure pump 8 into the anti-corrosion water pipe 4 on one side of the support column 1.

The pressure rod 11 rotates. At this time, the water inside the water collecting tank 13 is conveyed to the inside of the connecting plate 7 through the water suction nozzle 12 at the bottom of the pressure pump 8, and then through the anti-corrosion water pipe 4 on one side of the support column 1, the water source is conveyed to the water pipe to be detected. After connecting the anti-corrosion water pipe 4 with the water pipe to be detected, close the water valve, and then continue to press the water pump handle 10 to inject water into the water pipe to be detected. As the pointer of the pressure gauge 2 slowly rises, a water pressure test is carried out on the water source. During the test, the radiation-proof layer 501 and the heat insulation plate 502 inside the sun protection mechanism 5 protect the anti-corrosion water pipe 4. Finally, according to the detection requirements, adjust the upper movable plate 602 and the two side movable plates 604 inside the caliber adjustment mechanism 6. After determining the caliber, fix the upper movable plate 602 through the adjustment port 605. This is the working principle of this simple water pressure test device.
