Field of the Invention The present invention relates to a toilet pick-and-place device, and more particularly to a shut-off valve controlled pressure air escaping and unloading system. BACKGROUND OF THE INVENTION For the pick-and-place of storage, the commonly used pick-and-place device is a vacuum suction truck. The shortage of vacuum suction trucks is as follows: 1. The core equipment of the toilet system is a vacuum pump. The system consists of: oil and gas separator, water separator, strainer, anti-overflow valve, vacuum pressure gauge, etc. Complex; Second, the storage depth is difficult to exceed seven meters, which is not conducive to the implementation of the closed storage mode and the terrain-constrained storage device, to expand the storage scale in the depth direction development mode; Working in the negative pressure state, the tank body is required to have high compressive strength, and the material and processing requirements of the carrying tank body are high; Fourth, the vacuum pump allows continuous working time is short, and the maintenance and maintenance requirements are high; 5. The handling steps are cumbersome; Pressure air from the storage device is not supported for defecation. In addition, China's prior patent application, application number: 00113266.0, publication date: October 10, 2001, which discloses a positive pressure take-up and a double-pressure toilet system based on positive pressure take-up, these two positive The pressure-receiving system device combines the escaping tube and the remnant functioning device in the tube after the defecating, and relies on the air in the carrying tank body to press the remaining space in the tube to return to the collecting device to realize the convulsion. The rest of the pipe will be eliminated. Although this kind of structure can ensure the removal of the residual space in the pipe, and achieve environmental protection and cleansing, it can also support the same set of toilets to ensure the removal of the toilet in the toilet. Therefore, it is difficult to design the structure of the drain pipe port of the carrier body device, because the port portion must be opened when the residual is removed, so that the pressurized air in the carrier tank can enter the pipe, and the pressure tube is pressed. Returning to the reservoir; and when performing forced unloading, it is required that the toilet tube must be closed, or at least the port portion of the toilet tube entering the carrier body must be closed to ensure the pressure of forced unloading. The air does not leak through the pipe; the simple solution is A valve is added to the appropriate part of the pipe, and the valve is opened and closed to adapt to the two different working modes of rest or forced unloading, but this will increase the cumbersome operation process. For the technical solution that the "pneumatic toilet device is not located on the pick-up device and is located in the storage facility or near the storage facility", the toilet device does not have the ability to force unloading. The method and system device can be called a pressurized air take-off method because the positive pressure take-up and the double pressure take-off method and the system device based on the positive pressure take-up are all implemented by the pressurized air filling method.
