Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a tunnel columnar water inflow metering device. Background Art

[0002] Tunnel projects often encounter water inrush during construction. Water inrush not only affects the construction progress, but may also threaten construction safety. Therefore, accurate measurement of tunnel water inrush is of great significance to construction decision-making and safety management. At present, commonly used methods for measuring water inrush include manual observation and measurement using buckets. However, these methods have many limitations and shortcomings.

[0003] The manual measurement method requires personnel to be on duty for a long time, which is time-consuming and labor-intensive, and has large human errors, making it impossible to achieve continuous and accurate monitoring.

Based on this, there is an urgent need for a water inflow metering device with a simple structure, moderate cost, accurate measurement and suitable for the tunnel environment to meet the needs of tunnel engineering for water inflow monitoring.

[0036] A connecting rod 6 supporting the water collecting funnel, used to support the water collecting funnel 1;

[0037] A bracket 3 supporting the water measuring bucket 2 and the waterproof box 4;

[0038] A bubble level 7, used to assist in adjusting the device to make it level before measuring begins;

[0039] The buffer rubber strips 10 on both sides are installed on the bracket 3 and are used to buffer the impact force when the water-measuring bucket 2 hits;

[0040] The pulse button 11 is installed on the bracket 3 and passes through the buffer rubber strips 10 on both sides. When it is hit by the impact block 205 of the water measuring funnel 2, a pulse signal is triggered; there are two pulse buttons 11, which are installed on both sides of the bracket 3. Each time they are hit by the water measuring funnel 2, a signal will be sent to the data collector with screen 5.

[0041] The waterproof box 4 is used to protect the internal data collector, the external power supply and the external storage device; the waterproof box 4 has a waterproof box door 401 that can be opened and closed, and a glass observation window 402 is provided on the waterproof box door 401, so that the display screen 501 of the data collector with screen 5 can be seen when the waterproof box door 401 is closed, and the empty space on the right side of the waterproof box 4 is reserved for placing the external power supply and the external storage device;

[0042] The data collector with screen 5 is electrically connected to the pulse button 11, and is used to receive the pulse signal and record the time and count; the data collector with screen includes a display screen 501, a power switch 502, a collection start button 503, a collection stop button 504, a USB / type-A type data interface 505, which is used to connect an external storage device, and a USB / type-A type power interface 506, which is used to connect an external power supply; it is powered by an external power supply power bank and uses an external storage device U disk for information storage.

[0043] The telescopic legs 8 are mounted at the bottom of the device and connected to the base 9 for adjusting the device to ensure that the device is in a horizontal state when in use.

[0044] The utility model provides a tunnel columnar water inflow metering device, the working principle of which is:

[0045] After connecting the screened data collector 5 of the device to an external storage device and an external power supply, place the device under the columnar gushing water and ensure that the water collecting funnel 1 can collect the gushing water;

[0046] Use telescopic legs 8 to adjust height and level to ensure that the device is level, so that the left water measuring bucket 201 and the right water measuring bucket 202 of the water measuring bucket 2 can measure 500ml of gushing water each time; bubble level 7 is used to assist in adjusting the device to make it level.

[0047] After pressing the power switch 502 of the data collector with screen 5, pressing the collection start button 503 starts the water inflow metering work.

[0048] The gushing water is injected into the water measuring bucket 2 through the water collecting funnel 1. The water measuring bucket 2 has two water measuring buckets of the same volume, namely the left water measuring bucket 201 and the right water measuring bucket 202, and there is a flat hourglass-shaped sealed container 203 below. A certain amount of water is filled in the container. Under the action of gravity, the water in the container will be concentrated on the right side. This is an example for easy understanding. In actual use, the water in the sealed container can also be initially on the left side, so that the water measuring bucket 2 tilts to the right side. At this time, the left water measuring bucket 201 collects the gushing water; after a certain amount of 500ml, the balance between the water in the left water measuring bucket 201 and the water on the right side of the hourglass-shaped sealed container 203 is broken, the water measuring bucket tilts to the left, and the left water measuring bucket 201 pours out the collected gushing water; at the same time, the impact block 205 hits the pulse button 11 to trigger a pulse signal; the water in the hourglass-shaped sealed container 203 flows to the left side and becomes the right water measuring bucket 202 to collect the gushing water. In this cycle, the left and right water measuring buckets collect and measure the water flow in turn.

[0049] The buffer rubber strips 10 on both sides are installed on the bracket 3 to reduce the impact force of the impact block 205 when overturning, thereby extending the service life of the device.

[0050] The waterproof box 4 is used to protect the internal screened data collector 5, the external power supply and the external storage device to prevent water from entering and causing damage. The screened data collector 5 is electrically connected to the pulse button 11, and can receive pulse signals and record time and count. Each time a signal is received, the current time is recorded, the number of received signals is accumulated, the accumulated water inflow is automatically calculated, and the data is stored in an external storage device.

[0051] When it is necessary to end the water inflow metering work, press the collection stop button 504 of the screen data collector 5 to stop the water inflow metering work.

[0052] The utility model provides a tunnel columnar water inflow metering device, which is a water inflow metering device with simple structure, accurate measurement and suitable for tunnel environment, and has the advantages of easy use, simple maintenance and low cost, and is particularly suitable for water inflow monitoring in tunnel engineering.

It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be considered as the protection scope of the present invention.
