Abstract

A high-water-level underground and semi-underground potato storage cavern automatic drainage system is composed of water collection pits distributed in the bottom face of a storage cavern, drainage wells located in the edge of the bottom face of the storage cavern, headrace channels communicating the water collection pits with the drainage wells respectively, and automatic water pumping devices installed in the drainage wells, wherein each automatic water pumping device comprises a drainage pump with a water pumping opening extending to the bottom of the corresponding drainage well, an alternating-current contactor which is connected to a working circuit of the drainage pump, a liquid level controller which is arranged in the corresponding drainage well and used for outputting electric signals, and a control circuit and a drainage pump alternating-current power supply connecting line which are connected between the alternating-current contactor and the liquid level controller. The high-water-level underground and semi-underground potato storage cavern automatic drainage system has the advantages that large-area water accumulation at the bottom of the storage cavern is avoided; water at the bottom of the storage cavern can be smoothly transferred to the drainage wells; full-automatic drainage without attended operation or manual operation is achieved, the defects of untimely drainage, high water level control randomness and unbalanced inlet and outlet of accumulated water in the storage cavern caused by manual control over drainage are overcome, and safety conditions of stored potatoes are improved.

Description

Underground, the semi-underground potato storing cellar automatic drain system of high water level

Technical field

This use is novel belongs to fixing structure, is specifically related to vegetable storage cellar for storing things.

Background technology

Ago, semi-underground Ma Malingshuzhuzangkujiao (storehouse) water discharge technology is divided into following several:

The first is that buttery ground line is designed to the gradient once, relies on the gravity flow of water to flow in sump when rainy season, water was large, then, by the interim water pump of artificial installation, water is discharged.The second is to dig in front of the door a gutter at warehouse-in, and the water of warehouse-in is intercepted to a part, when rainfall is little, water can be discharged along gutter, if when rainfall is large, flood directly covers gutter and enters in storehouse.Now Ku Nei also will continue to adopt artificial drainage.The third is in storage cellar, to dig in proportion several seepage mouths, in storehouse, have ponding by seepage mouth by water draining.If when ponding is too much, impeded drainage, and easily stop up, causing cannot draining, finally must be by manually water being extracted out with water pump.Above several drainage patterns time-consuming, take a lot of work, require great effort.When ponding overlong time, cause in storehouse humidity excessive, easily multiply harmful germ such as bacterium, fungi, if the halfway words of potato warehouse-in sterilization in autumn are easy to cause the rotten cellar for storing things of potato, make potato planting family and storage family cause very large economic loss.

Summary of the invention

The object of this invention is to provide underground, the semi-underground potato storing cellar automatic drain system of a kind of high water level, for discharging the ponding of potato storing cellar, overcome dewatering installation above shortcomings in the past.

Drainage system of the present utility model forms by being distributed in the sump of storage cellar bottom surface, the catch pit that is arranged in storage cellar bottom edge, the disposal ditches that is communicated with each sump and catch pit, the automatic water pumping device for water that is arranged on catch pit, automatic water pumping device for water wherein comprise drainage pump at the bottom of pump mouth extends catch pit, access drainage pump operating circuit A.C. contactor, be arranged on output electrical signals in catch pit ponding fluid level controller, be connected to control circuit, suction pump AC power line between A.C. contactor and fluid level controller.

The course of work of the present utility model is: the water entering in cellar for storing things flows into the sump that is distributed in the end, cellar for storing things along cement kiln bottom surface, then concentrates inflow catch pit through disposal ditches.When catch pit middle water level rises to setting upper, in limited time fluid level controller buoyancy aid raises up to conducting high signal wire, and control circuit starts A.C. contactor according to the signal of telecommunication of high signal wire output, and pump working power connection starts and continue to draw water, draining.Prescribe a time limit when water level drops to the lower of setting because drawing water, fluid level controller buoyancy aid is because of whereabouts conducting low level signal conductor, and control circuit cuts off pump working power supply according to the signal of telecommunication control A.C. contactor of low level signal conductor output and stops draining.As have again into water in storing, import water level after catch pit and rise to setting upper water pump starts again in limited time, so repeatedly, complete excessive ponding in unattended automatic discharge cellar for storing things.

Good effect of the present utility model is: the sump that bottom surface, cellar for storing things distributes, can avoid storing end larger area water.The disposal ditches of sump and connected set puddle and catch pit can be transferred to catch pit by the water at the end, cellar for storing things swimmingly.Be arranged on the self-draining arrangement in catch pit, realize without the artificial Full-automatic drainage of on duty, operation, avoided draining that manual control draining exists not in time, water level control is random large, unbalanced shortcoming is told, received to cellar for storing things internal water accumulation, improved the safety condition of cellar for storing things storage potato.

Brief description of the drawings

Fig. 2 is automatic water pumping device for water structure and work relationship schematic diagram in catch pit.

Detailed description of the invention

Consult Fig. 1, form equally distributed sump 2 in potato storing cellar cement bottom surface, construct catch pit 3 in a Jiao Jiao bottom surface of storage cellar bottom surface with upper/lower positions, between each sump and between sump and catch pit, be communicated with disposal ditches 4.

Consult Fig. 2, in catch pit 2, place fluid level controller 5, in the protective housing outside cellar for storing things, A.C. contactor 6 and control circuit 7 are installed.Fall into shaft bottom diving drainage pump 8.The signal input part of the output line connection control circuit 7 of fluid level controller 5, the output of control circuit 7 connects A.C. contactor 6.A.C. contactor 6 and drainage pump are by power line 9 incoming transport net electricity.

Claims

1. high water level is underground, semi-underground potato storing cellar automatic drain system, it is characterized in that: by the sump that is distributed in storage cellar bottom surface, be positioned at the catch pit of storage cellar bottom edge, be communicated with the disposal ditches of each sump and catch pit, be arranged on the automatic water pumping device for water composition in catch pit, automatic water pumping device for water wherein comprises the drainage pump at the bottom of pump mouth extends catch pit, the A.C. contactor of access drainage pump operating circuit, be arranged on the fluid level controller of output electrical signals in catch pit, be connected to the control circuit between A.C. contactor and fluid level controller, suction pump AC power line.
