Because the environment in the cave storage fresh-keeping chamber is slightly influenced by seasons, the cave storage fresh-keeping chamber is suitable for long-time storage of fruits and vegetables and is favored by fruit growers and agricultural enterprises. However, in actual operation, when excavating the cave, all can receive the restriction of relief usually, probably make the entrance to a cave expose for a long time in the sunshine, in the sunshine probably passes through the entrance to a cave for a long time and shines into the cave of cave in the cave for the internal temperature in the cave has deviated from original stability, receives the influence that external sunshine directly penetrates great, especially in hot summer, because aforementioned reason, the internal temperature difference is very big early or late in the cave, is unfavorable for the fresh-keeping of fruit vegetables.

Aiming at the problems, at present, fruit growers or agricultural enterprises usually plug door plates at the hole openings according to the weather conditions, namely, the hole openings are plugged when the weather is hot and the sun shines directly for a long time, so as to avoid the too high temperature in the hole bodies; when the weather is cool and the weather is cloudy, the opening is opened, so that ventilation is facilitated. However, this kind of artificially controlling the blocking and opening of the opening according to the weather is very inconvenient, strong and difficult to control.

Disclosure of Invention

The invention aims to provide a cave storage fresh-keeping chamber for fruits and vegetables, and aims to solve the technical problems that the existing cave storage fresh-keeping chamber for fruits and vegetables is troublesome to operate and high in strength when the internal temperature is controlled in hot summer.

The present invention provides the following basic scheme: the hole-storing fresh-keeping chamber for fruits and vegetables comprises a hole body, wherein the hole body is provided with a hole, a door plate is arranged at the hole, the upper side and the lower side of the hole are respectively provided with a sliding rail, the door plate is arranged in the two sliding rails in a sliding manner, and a first spring is arranged between one side of the door plate and the side wall of the hole body; the door plate pushing mechanism comprises a piston barrel arranged on one side of the opening, a motor, a rack arranged at the lower end of the door plate, an iron block arranged on one side of the door plate far away from the first spring and an electromagnet arranged on one side of the opening opposite to the iron block; the mercury is filled in the piston barrel, a piston is arranged in the piston barrel in a sliding mode and located on the mercury liquid level, an insulating support rod is arranged at the upper end of the piston, an electric contact piece is arranged at the upper end of the insulating support rod, a lead is connected to the electric contact piece, and the lead is connected with a power supply; a conductive block is arranged above the piston barrel, the conductive block is electrically connected with both a power line of the motor and a power line of the electromagnet, and when the piston slides upwards, the electric contact piece can be contacted with the conductive block; the motor is connected with an incomplete gear which can be meshed with the rack, the incomplete gear is positioned below one side of the opening close to the first spring, and when the door plate closes the opening, the rack is separated from the incomplete gear.

Adopt above-mentioned basic scheme, the door plant slides and locates in two slide rails, and the door plant can slide to both sides promptly to realize the shutoff of entrance to a cave with open, and first spring has the effect of a restriction to the slip of door plant, does not receive other exogenic actions as the door plant and acts on, and under the effect of first spring, the door plant can be back to do the motion of replying, with the open ventilation of realization entrance to a cave.

The door plate pushing mechanism is used for acting on the door plate and controlling the door plate to slide in the two sliding rails. Wherein mercury in the piston bucket when ambient temperature is higher, can thermal expansion, promote piston upward movement, promote the electric contact upward movement on the bracing piece promptly, when the electric contact move to with the conducting block contact, motor and electro-magnet switch on, the motor switches on and drives incomplete gear revolve, incomplete gear and rack toothing, it slides towards the electro-magnet direction to promote the door plant, and simultaneously, the electro-magnet also has the suction effect to the iron plate on the door plant, it slides towards the electro-magnet direction to drive the door plant, until with the entrance to a cave shutoff, avoid sunshine to penetrate directly, rise the internal portion in hole's temperature.
