Through setting up annular gasbag to open at the water level and aerify for annular gasbag behind exceeding lid roof upper surface, can form to block outside overflow, avoid outside overflow to get into the parking stall.
Because the annular top cover is integrally annular, the downward collapse of the free end of the annular bladder is avoided. This is because the annular air bag is water-receiving on four sides, and the pressure is roughly equivalent on four sides, and the top of annular air bag is because with annular top cap rigid, can not be compressed, therefore, the free end of annular air bag also can not inwards topple over.
Because there are first tractive line and second tractive line, and the tractive module gives the pretightning force to first tractive line and second tractive line all the time, consequently, the unable extension of first tractive line is out of shape, can support the middle part of living annular gasbag and receive outside water pressure inwards to collapse.
Because the annular air bag is clamped between the first traction rope and the second traction rope, the first traction rope and the second traction rope can limit the form of the annular air bag after deflation in the resetting process of the deflation annular air bag, and the first traction rope and the second traction rope are wound with pretightening force all the time in the deflation process, so that the annular air bag can be folded between the first traction rope and the second traction rope.
Through setting up first tractive rope and second tractive rope, and the tractive module is the two with the pretightning force tractive all the time, consequently, at the gassing reset in-process, annular top cap also can receive the pulling force automatic correction of first tractive rope and second tractive rope, finally gets back to initial position.
By arranging the one-way valve, water on the ground cannot enter the drain pipe and the drain channel; through setting up the water pump, can take the water in the parking stall out the parking stall, even constantly rainy, also can prevent that the water in the parking stall from rising.
Because first conductor sets up in the lid roof, and first solenoid valve sets up in the lateral wall of lid with the end of intaking together, consequently, when first conductor capacitance value falls to being less than below the electric capacity threshold value, can avoid the water pump to take out and damage because of anhydrous by closing first solenoid valve and water pump.
The control module controls the air pump to inflate after the external temperature rise is larger than the temperature rise threshold value, the annular air bag can be lifted in time, and the loss of people and vehicles around the vehicle caused by vehicle detonation is prevented. Meanwhile, the annular air bag is made of flame-retardant materials and is attached with the metal wire mesh, so that shock waves and splashed articles generated by deflagration can be blocked, and the combustion range can be controlled.
Through setting up the ditch edge, annular top cap is when covering and establishing to the ditch edge, and the upper surface can with ground parallel and level, and coincide with the parking stall line, the user does not have any difference with ordinary parking stall in the use impression when meetting urban waterlogging and torrential rain.
Because the whippletree is higher than the top surface of lid when the lock frame is in the landing position, sets up the second conductor in the whippletree, sets up the inlet end again in the top of whippletree when the lock frame is in the landing position, consequently, is greater than the electric capacity threshold value at second conductor capacitance value, means that water does not cover the inlet end time control second solenoid valve and closes to control the air pump pressurize, can avoid the air pump to damage. When the fourth signal is received, namely the water level is reduced to be lower than the cross bar, the second electromagnetic valve and the air pump are opened, the annular air bag can be continuously inflated, and the collapse of the annular air bag is avoided.
The parking space line has the advantages that on the four sides of the parking space line, at least two first traction ropes and two second traction ropes on each side can better support the annular air bag and can better limit the shape of the annular air bag after deflation, so that the annular air bag is superposed between the first traction ropes and the second traction ropes.

Specifically, when the pulling torques generated by the first pulling rope 25 and the second pulling rope 25 due to the deformation force of the annular air bag 22 are larger than the output torque of the constant-torque winch, the constant-torque winch releases the first pulling rope 24 and the second pulling rope 25 until the annular air bag 22 is not deformed, and the torques are balanced. When the pulling torque generated by the first pulling rope 25 and the second pulling rope 25 due to the reset force of the annular air bag 22 is smaller than the output torque of the constant-torque winch, the constant-torque winch winds the first pulling rope 24 and the second pulling rope 25 until the annular air bag 22 is reset, and the torques are balanced.
The wireless module is arranged in the base 11 and used for communicating with the cloud server and receiving an instruction of the cloud server.
The control module is disposed in the base 11 and electrically connected to the motor, the detection unit, the temperature sensing module 6, the water pump 31, the first electromagnetic valve, the air pump 41, the second electromagnetic valve, and the wireless module, respectively. The control module controls the motor to drive the lock frame 12 to rotate to the descending position after receiving a parking space entering instruction sent by the cloud server through the wireless module, and controls the motor to drive the lock frame to rotate to the ascending position after receiving a parking space leaving instruction sent by the cloud server through the wireless module.
After the locking frame 12 is located at the falling position, if a first signal is received, the control module controls the water pump 31, the first electromagnetic valve, the air pump 41 and the second electromagnetic valve to be opened; if a second signal is received, the water pump 31 and the first electromagnetic valve are controlled to be closed; the second solenoid valve is controlled to close and the air pump 41 is controlled to maintain pressure if the third signal is received, and the second solenoid valve and the air pump 41 are controlled to open if the fourth signal is received.
After the lock frame 12 is located at the falling position, the control module receives the temperature signal every first period and calculates an external temperature rise value in a second period before the recording, and if the external temperature rise value is greater than a temperature rise threshold value, the air pump 31 and the second electromagnetic valve are controlled to be opened.
After the vehicle is parked in a parking space, if urban waterlogging or heavy rain occurs, the detection unit first sends a first signal after the overflow water submerges the top surface of the cover 112. After receiving the first signal, the control module immediately controls the water pump 31, the first electromagnetic valve, the air pump 41 and the second electromagnetic valve to be opened, and the annular air bag 22 is inflated until the annular air bag is ejected out as shown in fig. 6. At the same time, the water pump 31 begins pumping water, which is drained out of the drain 92 through the drain pipe 32. If the water is gradually drained and does not sink the top surface of the cover 112, the control module controls the water pump 31 and the first solenoid valve to close. If the water is still rising and begins to cross the cross bar, the detection unit sends a third signal, and the control module controls the air pump 41 to maintain pressure and controls the second electromagnetic valve to close. If the water level is lower than the horizontal bar after water pumping, the control module controls the air pump 41 and the second electromagnetic valve to be opened again. If the temperature rise of the battery of the electric automobile is out of control due to short circuit, the temperature sensing module can sense the temperature rise, and the control module controls the air pump 31 to inflate after the temperature rise exceeds a threshold value, so that damage to people and vehicles around due to deflagration can be prevented. After the control module receives a reset instruction sent by the cloud server through the wireless module, the air pump 41 is controlled to deflate.
In this embodiment, the capacitance of the first conductor rises above the capacitance threshold when there is water on the top wall of the cover 112, so that it can be determined by detecting the capacitance of the first conductor that the water level has risen above the top wall upper surface of the cover 112, or that the water level has fallen below the top wall upper surface of the cover. In the embodiment, the annular air bag 22 is arranged, and the annular air bag 22 is inflated after the water level rises to exceed the upper surface of the top wall of the cover body 112, so that the external overflow can be blocked, and the external overflow is prevented from entering the parking space. Since the annular top cover 23 is of generally annular shape, the downward collapse of the free end of the annular bladder 22 is avoided. This is because the annular bladder 22 is water-permeable on four sides, the water pressure on four sides is substantially equivalent, and the top end of the annular bladder 22 is fixed to the annular top cover 23, and the annular top cover 23 is rigid and cannot be compressed, so that the free end of the annular bladder 22 will not fall inward. Because the first traction rope 24 and the second traction rope 25 exist and the traction module 5 always applies pretightening force to the first traction rope 24 and the second traction rope 25, the first traction rope 24 cannot be elongated and deformed, and the middle part of the annular air bag 22 can be supported to be inwards collapsed by external water pressure. Because the first traction rope 24 and the second traction rope 25 sandwich the annular airbag 22, the first traction rope 24 and the second traction rope 25 can limit the deflated state of the annular airbag 22 in the process of resetting the deflated annular airbag 22, and the first traction rope 24 and the second traction rope 25 are wound with pretightening force all the time in the deflation process, so that the annular airbag 22 can be folded and retracted between the first traction rope 24 and the second traction rope 25. In the embodiment, the first pulling rope 24 and the second pulling rope 25 are arranged, and the pulling module always pulls the first pulling rope and the second pulling rope with pretightening force, so that the annular top cover 23 can be automatically corrected by the pulling force of the first pulling rope 24 and the second pulling rope 25 in the deflation resetting process, and finally returns to the initial position. In the embodiment, the one-way valve 33 is arranged, so that water on the ground cannot enter the drain pipe 32 and the drain channel; by arranging the water pump 31, water in the parking space can be pumped out of the parking space, and the water in the parking space can be prevented from rising even if the vehicle continuously rains. Because the first conductor is disposed on the top wall of the cover 112, and the first electromagnetic valve is disposed on the side wall of the cover 112 together with the water inlet 311, when the capacitance value of the first conductor is reduced to be lower than the capacitance threshold value, the first electromagnetic valve and the water pump 31 can be closed, thereby preventing the water pump 31 from being damaged due to water being pumped out. The control module controls the air pump 31 to inflate when the external temperature rise is larger than the temperature rise threshold value, so that the annular air bag 22 can be lifted in time, and the loss of people and vehicles around caused by vehicle explosion is prevented. Meanwhile, since the annular airbag 22 is made of a flame retardant material and is attached with a wire mesh, it is possible to block shock waves and splashed articles generated by the explosion and to control the combustion range. Through setting up ditch edge 911, annular top cap 23 is when covering to ditch edge 911, and the upper surface can with ground parallel and level, and coincide with the parking stall line, the user does not have any difference with ordinary parking stall in the use impression when not meetting urban waterlogging and torrential rain. Because the bar 122 is higher than the top surface of the cover 112 when the lock frame 12 is at the landing position, the second conductor is disposed on the bar, and the air inlet end is disposed on the top end of the bar 122 when the lock frame 12 is at the landing position, the capacitance value of the second conductor is greater than the capacitance threshold value, which means that the second electromagnetic valve is controlled to close when water covers the air inlet end 411, and the air pump 41 is controlled to maintain pressure, so that the air pump 41 can be prevented from being damaged. When the fourth signal is received, that is, the water level is lowered to below the horizontal bar, the second electromagnetic valve and the air pump 41 are opened, so that the annular air bag 22 can be continuously inflated, and the collapse of the annular air bag 22 is avoided. In this embodiment, at least two first pulling ropes 24 and two second pulling ropes 25 are provided on each of the four sides of the parking space line, so that the annular airbag 22 can be better supported, and the deflated state of the annular airbag 22 can be better limited, so that the annular airbag 22 is overlapped between the first pulling ropes 24 and the second pulling ropes 25.
The description of the above specification and examples is intended to be illustrative of the scope of the present application and is not intended to be limiting.
