technical field

The invention relates to an automatic water pumping device and method in a tunnel.

Background technique

In the process of tunnel construction, waterproofing and drainage is a very important project. Tunnel waterproofing and drainage follow the principle of "combining prevention, blocking, interception and drainage, adapting measures to local conditions and comprehensive management", and taking practical and reliable measures to achieve reliable waterproofing, smooth drainage, and economical and reasonable purposes. The accumulation of water in the tunnel mainly comes from the inrush of water in the tunnel, artificial water, etc., which brings a certain degree of influence to the tunnel construction. If there is too much water, it will hinder the construction and affect the construction progress. Corresponding organizational and technical measures should be taken to eliminate or reduce the adverse effects of water accumulation during construction on the project.

At present, the stagnant water in the water collecting well in the tunnel is mainly guarded by ordinary manual inspections for 24 hours, and the amount of water in the water collecting well is monitored in real time, so as to avoid flooding the tunnel ground due to excessive water accumulation, and it also takes up a lot of manpower and material resources. In practical engineering, how to solve this problem more safely, intelligently and automatically is one of the urgent problems to be solved in the process of automatic construction in order to discharge the accumulated water in the water collection well in a timely and efficient manner.

SUMMARY OF THE INVENTION

In order to solve the above problems, the present invention proposes an automatic water pumping device and method in the tunnel. The invention solves the problem of intelligent and automatic water pumping and drainage in the tunnel, saves manpower and material resources, and can automatically control the drainage in real time, avoiding the need for manual 24 The inefficiency of hourly duty.

In order to achieve the above object, the present invention adopts the following technical solutions:

An automatic water pumping device in a tunnel, comprising a suspension ball, a fulcrum, a lever, a water pumping mechanism, a self-locking switch and a double control switch, wherein the suspension ball is arranged at one end of the lever, has a certain degree of freedom, and can rise and fall with the water level , the other side of the lever is provided with a contact block, the middle of the lever is provided with a fulcrum, so that both ends of the lever are suspended, the upper and lower positions of the contact block are each provided with a self-locking switch, when the contact block moves up and down with the lever, The dual-control switch communicates with each self-locking switch and controls the action of the pumping mechanism according to the conduction state.

As a further limitation, the suspension ball is connected with the lever through a connecting rod.

As a further limitation, the connecting rod passes through a fixing ring, the fixing ring is fixed on the bank of the tunnel, and the connecting rod can move up and down in the fixing ring.

As a further limitation, there are at least two fixed rings, and they are arranged with concentric shafts to control the stability of the suspension ball when it ascends and descends, so as to keep it from deviating during the movement and to move vertically up and down.

As a further limitation, the suspension ball can float up and down according to the water level of the water tank, the position of the suspension ball can reflect the height of the water level, and the action of the pumping mechanism is indirectly controlled by the position of the suspension ball.

As a further limitation, the lever rotates clockwise or counterclockwise through the fulcrum. When the water level rises, it drives the contact block to descend and triggers the self-locking switch below to indirectly control the action of the pumping mechanism; when the water level drops, it drives the contact block to rise to trigger the self-locking switch above. The lock switch indirectly controls the action of the pumping mechanism.

As a further limitation, the contact block is a trapezoidal block, which can rotate along with the up-and-down movement, so as to better align the self-locking switch and trigger the self-locking switch.

As a further limitation, there are two double-control switches at the upper and lower sides. When the upper double-control switch is initially in the second position, if the water level rises to a predetermined position, the lower double-control switch is turned to the fourth position through the self-locking switch. , the double-control switch is connected with the pumping mechanism; when the water level drops to a certain position, the upper double-control switch is hit to the first position through the self-locking switch, and the double-control switch is disconnected from the pumping mechanism at this time. When it rises to the specified position, the lower side switch is hit to the third position through the self-locking switch, and the double-control switch is connected to the pumping mechanism at this time.

As a further limitation, after the self-locking switch is docked with the contact block, it will be squeezed by the contact block under the influence of buoyancy, and the self-locking switch will be pressed and rotated to control the double-control switch on one side; when the same self-locking switch is pressed again After being squeezed by the contact block, the self-locking switch will automatically pop out from the original pressed state, thereby driving the dual-control switch to turn to the other side.

The working method based on the above device includes the following steps:

Install the automatic pumping device and control the initial position of the double-control switch to ensure that the pumping mechanism does not work at this time;

When the water level rises to the specified position, the suspension ball also rises to the corresponding height, and the contact block is lowered by the lever to collide with the self-locking switch below, triggering the self-locking switch below, and at the same time driving the double-control switch on the lower side of the control circuit to rotate , the pumping mechanism starts to pump water;

Continuously pumping water until the water level drops to a certain height, the suspension ball also drops to the corresponding height, and the contact block rises to collide with the upper self-locking switch through the lever, triggering the upper self-locking switch, and at the same time driving the upper side of the control circuit. Turn, the pumping mechanism stops working;

This cycle repeats, the water level rises to the specified height, and the water will be pumped. When the water level is pumped to a certain level, the pumping will stop, and when the water level rises to the specified height again, it will start to pump water.

Compared with the prior art, the beneficial effects of the present invention are:

1) The invention is simple to operate, easy to use, low in cost and economical;

2) The present invention utilizes the effect of buoyancy on the suspending ball, which can indirectly control the switch of the water pump, and cleverly utilizes the performance of the double-control switch, so that the water level will trigger the switch when the water level rises and falls, reducing manpower and material resources;

3) In the present invention, when the water level rises but does not reach the specified position, the switch is turned off to not drain water, and the switch is turned on to drain water until the specified position, which can intelligently drain water and save resources;

4) The present invention is safe and efficient, the water in the water tank will not overflow when left unattended, and it will automatically drain when it rises to a specified position, so that the water level is always kept within a safe range.

As shown in Figure 1, an automatic water pumping device in a tunnel includes: a suspension ball 1, a connecting rod 2, a fixed ring 3, a fulcrum 4, a lever 5, a trapezoidal block 6, a self-locking switch 7, a dual control switch 8, a power supply, Suction pump 10 and sink 12. The suspension ball 1 is located on the water surface and can rise and fall with the water level; the upper side of the connecting rod 2 is connected with the lever 5, and the lower side is connected with the suspension ball 1; the fixing ring 3 is passed through by the connecting rod 2; the fulcrum 4 is located between the levers 5, It is hinged with the lever 5; the trapezoidal block 6 is located on the side of the lever 5 and can move up and down with the lever 5; the self-locking switch 7 is one up and down, which can be connected to the trapezoidal block 6; There is a switch.

The invention has a simple structure, is easy to operate, and is intelligent and automated to improve the control pumping efficiency, and at the same time save more resources.

The suspension ball 1 can float up and down according to the water level of the water tank 12 , the height of the suspension ball 1 can reflect the water level, and the switch of the water pump 10 can be indirectly controlled by the height of the suspension ball 1 .

The upper side of the connecting rod 2 is hinged with the lever 5, and the lower side is fixedly connected with the suspension ball 1. When the water level is high, the suspension ball 1 drives the connecting rod 2 to rise, and when the water level is low, it drives the connecting rod 2 to descend.

There are two fixed circles 3 up and down, which can be used to control the stability of the suspension ball 1 when it rises and falls, so as to keep it from deviating during the movement, and to move vertically up and down.

The fulcrum 4 serves as the basis for the movement of the lever 5, and the hinged connection between the fulcrum 4 and the lever 5 ensures the stability of the movement of the lever 5, and will not skew during the rotation.

The lever 5 rotates clockwise or counterclockwise through the fulcrum 4. When the water level rises, it drives the left trapezoidal block 6 to descend to trigger the lower self-locking switch 7 to indirectly control the switch of the water pump 10; when the water level drops, it drives the left trapezoidal block 6 to rise to trigger the upper automatic switch. The lock switch 7 indirectly controls the switch of the water pump 10 .

The shape of the trapezoidal block 6 is set as a trapezoid because it rotates along with the up and down movement, and the trapezoidal shape can better flatten the self-locking switch 7 and trigger the self-locking switch 7 .

After the self-locking switch 7 is docked with the trapezoidal block 6, it will be squeezed by the trapezoidal block 6 under the influence of the right buoyancy, and the self-locking switch 7 will be pressed and turn the double-control switch 8 on one side of the control circuit; After the locking switch 7 is squeezed by the trapezoidal block 6 again, the self-locking switch 7 will automatically pop out from the original pressed state (similar to the working principle of a ballpoint pen), thereby driving the double-control switch 8 on one side of the control circuit to turn to the other side.

As shown in Figure 2, there is one double-control switch 8 at the top and bottom. When the upper switch is initially on the ② side, if the water level rises to a predetermined position, the lower switch is turned to ④ through the self-locking switch 7, and the circuit is connected. The suction pump 10 starts to work; when the water level drops to a certain position, the upper switch is turned to ① through the self-locking switch 7, and the circuit is disconnected at this time, and the suction pump 10 stops working; when the water level rises to the specified position again, the The self-locking switch 7 turns the lower switch to ③, the circuit is connected at this time, and the suction pump 10 starts to work; when the water level drops or rises again, the working principle is the same, and the switch combination is one cycle every 4 times.

As shown in Figure 3, based on the above-mentioned method for an automatic water pumping device in a tunnel, the method includes the following steps:

1. Install the automatic water pumping device first. The initial position of the double-control switch 8 inside the control circuit is ②③, which is an open circuit, and the water pump 10 does not work;

2. When the water level in the water tank 12 rises to the specified position, the suspension ball 1 also rises to the corresponding height, and the left trapezoidal block 6 is lowered through the lever 5 to collide with the lower self-locking switch 7, triggering the lower self-locking switch 7, and at the same time Drive the double-control switch 8 on the lower side of the control circuit to rotate, and hit ④, the circuit is connected at this time, and the water pump 10 starts to pump water;

3. The water pump 10 keeps pumping water until the water level in the water tank 12 drops to a certain height, the suspension ball 1 also drops to the corresponding height, and the left trapezoidal block 6 rises through the lever 5 to collide with the upper self-locking switch 7, triggering the upper self-locking switch 7. Lock the switch 7, and at the same time drive the double-control switch 8 on the upper side of the control circuit to rotate, and hit ①, the circuit is disconnected at this time, and the water pump 10 stops working;

4. In this cycle, the water level will rise to the specified height, and the water will be pumped. When the water level is pumped to a certain level, it will stop pumping. When the water level rises to the specified height again, it will start pumping again.
