Fig. 1 to 9 show an emergency escape apparatus for urban waterlogging according to the present invention, comprising:

the storage assembly 1 is fixed on a wall surface, the storage assembly 1 comprises an electric locking assembly 11, a shell 12 and a baffle 13, and the electric locking assembly 11 can be automatically unlocked when receiving an unlocking signal; a cavity 121 is formed inside the housing 12, an opening 122 communicated with the cavity 121 is formed at the bottom of the housing 12, and a closed structure is preferably arranged above the housing 12 so as to be waterproof and dustproof; one end of the baffle 13 is hinged with the shell 12 so that the baffle 13 can rotate around the hinged position, and the other end of the baffle 13 is detachably connected with the baffle 13 through the electric locking assembly 11, and when the electric locking assembly 11 is locked and unlocked, the baffle 13 covers the opening 122 or rotates away from the opening 122;

a collapsible ladder 2 switchable between a collapsed state and an expanded state, one end of the collapsible ladder 2 being fixed within the housing 12 and the other end being a free end;

as shown in fig. 1, 3 and 7, when the baffle 13 covers the opening 122, the folding ladder is in a folded state and is accommodated in the cavity 121;

as shown in fig. 4, when the baffle 13 leaves the opening 122, the collapsible ladder 2 can be released from the collapsed state to become the unfolded state, and the free end falls out of the opening 122;

and the liquid level sensor 3 is used for detecting the water level height and sending water level data, and when the liquid level sensor 3 is actually installed, the liquid level sensor can be installed at a position lower than the storage assembly 1, so that the water level information can be conveniently detected in advance, and the storage assembly 1 is not submerged by water together. On concrete position, for example, the height of wading can be marked to the both sides of some south rainy city's formula highway sections that sink in south, install level sensor 3 on the road both sides wall with dangerous height of wading level, need install level sensor 3 in rain-proof position as far as possible simultaneously, avoid direct rainwater that falls and along the rainwater that the wall flow down to arouse the false detection.

And the controller 4 is electrically connected with the liquid level sensor 3 and the electric locking component 11 respectively, can receive the water level data, judges whether to send the unlocking signal to the electric locking component 11 according to whether the water level data exceeds a safety range, and sends the unlocking signal to the electric locking component 11 when the water level data exceeds the safety range so as to control the electric locking component 11 to unlock.

The wall surface is a substantially vertical surface, and includes a relatively large wall surface or an outer wall surface of a roadside balustrade with a small area on a roadside above a sunken tunnel in a city, and the opening 122 can face downward and has a certain distance from the ground so that the foldable ladder 2 can have a sufficient falling distance after the storage assembly 1 is fixed thereon. The collapsible ladder 2 is preferably a flexible ladder, such as a rope ladder, which facilitates easier falling out of the opening 122 when the flap 13 is opened.

The storage assembly 1 can be fixed on a wall surface of a place where waterlogging easily occurs in a city, and the foldable ladder 2 in the storage assembly 1 is stored in the cavity 121 of the shell 12 in a folded state when the water level is low and no dangerous situation occurs, so that the adverse effect of the external environment on the foldable ladder 2 is avoided, and the standby service life of the foldable ladder is prolonged; when the water level is high and a dangerous situation is possibly caused, the controller 4 sends an unlocking signal to unlock the electric locking assembly 11, and the baffle 13 below the unlocked shell 12 can open the exposed opening 122, so that the foldable ladder 2 falls out of the opening 122 to be in an unfolded state, a ladder for a person falling into water to climb is formed, and the survival probability of the person falling into water is improved. The state of the foldable ladder 2 can be changed on the premise that one end of the foldable ladder is connected with the free end of the other end of the foldable ladder by utilizing gravity, and the foldable ladder can be unfolded in the falling process along with the gravity of the foldable ladder 2, so that a mechanism is not needed to be additionally arranged, the foldable ladder is simpler, and the foldable ladder 2 cannot be unfolded easily due to mechanical failure; the foldable ladder 2 can be rolled up by using a roller to be changed into a folded state, and then the roller is driven by a motor to rotate and unfold when the foldable ladder is required to be changed into an unfolded state by adopting an auxiliary tool, so that the situation that the foldable ladder 2 cannot be unfolded by itself when the foldable ladder is required to be unfolded due to long-term folding and solidification can be prevented.

In the aspect of judging whether the water level is in a dangerous condition or not, the liquid level sensor 3 can detect the height of the water level in time and feed the water level data back to the controller 4, if the controller 4 finds that the water level data exceeds the safety range, the water level is considered to be too high, and an unlocking signal is sent to the electric locking component 11, so that the foldable ladder 2 is unfolded from the opening 122 and falls out; if the water level data does not exceed the safe range, the controller 4 will not send out the unlocking signal, and the collapsible ladder 2 can be always stored in the housing 12 in the collapsed state ready for unfolding.
