Abstract

FIELD: agriculture.

SUBSTANCE: group automatic water bowl for animals comprises a drinking-cup (1), an electric heater (8) with a temperature controller (10) and a water level controller, for example, the valve-float mechanism (5). The automatic water bowl is equipped with a storage vessel (4) located on the lower level than the drinking-cup, and also a floating electric pump (3) embedded between the drinking-cup and the storage vessel, connected through the control unit (13) with motion sensors (12). The electric heater and the water level controller are located in the storage vessel. The drinking-cup is made with the ability to flow the water from it to the storage vessel. In the storage vessel an actuator (6) can be located, driven by the wind-power unit (7).

EFFECT: reduced energy costs for heating water.

Description

The invention relates to devices for drinking animals.

Known group drinker containing a container, a valve-float mechanism and an electric heater. (Copyright certificate No. 447136. Kazakh Research Institute of Mechanization and Electrification of Agriculture, A01K 7/02). Its disadvantage is the low resistance to icing.

A group automatic drinker is free from these drawbacks (USSR Author's Certificate No. 1207448 A01K 7/04, 7/02), adopted as a prototype containing a drinking bowl, an electric heater and a valve-float mechanism, characterized in that the valve shuts off the water supply under the action of the spring, and the connection between the float and the valve allows the float to move freely vertically upward without breaking if the water in the drinking bowl accidentally freezes. The disadvantage of such a drinker is the need to have an electric heater, as well as a valve-float mechanism and a water supply network of oversized (compared to the average daily) power and throughput, respectively, in order to ensure a sufficient supply of water of the required temperature during its peak consumption during animal drinking. The consumption of electric energy from the network for heating water and covering heat losses is also great.

The objective of the invention is to improve the operational characteristics of a group drinker by providing animals with heated water in sufficient quantities during its peak consumption, as well as by reducing energy costs for heating water.

This goal is achieved due to the fact that the drinker is equipped with an accumulating tank located at a level below the bowl, cut between the bowl and the tank by an electric pump connected through a control device with motion sensors, an electric heater and a valve-float mechanism are placed in the tank, and the bowl is made with the possibility of overflowing water from it into a container. And also due to the fact that an activator with a drive from a wind turbine is placed in the tank. At the same time, a supply of water and heat is provided for use during intensive water consumption, heat losses are reduced during the period when animals do not consume water, and part of the energy of the electric network is replaced by renewable alternative energy from the wind turbine.

The drawing (Figure 1) shows the proposed group car drinker for animals.

It contains a drinking bowl 1 connected by a window 2 and a low-pressure floating centrifugal electric pump 3 embedded in the bottom of the bowl with a heat-insulating storage tank 4 located lower in level. Inside the storage tank there is an automatic water level regulator, for example, a valve-float mechanism 5, activator 6 with a drive from wind turbine 7, electric heater 8, temperature sensor 9 with an output through temperature controller 10 to electric heater 8 and power limiter of wind turbine 11. In close proximity Motion sensors 12 are placed from the drinking bowl with the output through the control device 13 to the electric pump 3.

A group car drinker for animals works as follows.

Suppose that in the initial state, the storage tank 4 is filled with water, the temperature necessary for drinking animals. In this case, the valve-float mechanism 5 blocked the water from the water supply, the electric heater 8 and the electric pump 3 are de-energized, the bowl 1 is empty, the power of the wind turbine 11, for example, by turning the plane of its wind turbine along the wind direction is limited to zero and as a result the activator 6 does not rotate.

At the very beginning of the period of drinking, when approaching the automatic watering of animals, motion sensors 12 will work and through the control device 13 they will turn on the electric pump. The drinking bowl will be filled with warm water from the upper zone of the storage tank 4, excess water through the edges of the bowl and window 2 will be poured back into the storage tank.

During the period of drinking, an intensive selection of water from the drinking bowl and, consequently, from the storage tank 4 will begin. The water level in the tank will decrease, the valve-float mechanism 5 will open the access of cold water from the water supply to the lower part of the storage tank. With a small throughput of the valve-float mechanism and the water supply network, which in the conditions of agricultural production is most often observed, a sufficient amount of water for drinking will be provided due to the supply of warm water in the storage tank. The water level in the tank, despite its influx from the water supply, will decrease, while the zone of cold water in the lower part of the tank will expand and the zone of warm water in the upper part of the tank will narrow. In the drinking bowl, however, thanks to the floating electric pump, warm water will be taken from the upper zone of the storage tank.

At the same time, as soon as cold water begins to wash the temperature sensor 9 by its signal, the temperature controller 10 through the power limiter 11 will give permission to increase the power of the wind turbine 7, the activator will begin to rotate, converting the mechanical energy coming from the wind turbine shaft into heat. The temperature regulator will additionally receive a signal to turn on the electric heater, operating from the electric network, only with light wind or its complete absence.

The volume of the storage tank is designed so that the supply of warm water ends at the end of the drinking period. As soon as the animals leave the area where the drinker is located, motion sensors through the control device will turn off the electric pump. Through a disconnected electric pump, water will leave the drinking bowl, which will prevent heat loss to the surrounding space between drinks. The water level in the tank and its temperature will begin to rise from that moment and, as soon as they reach the set values, the level controller will stop the water supply to the drinking bowl, and the temperature controller will turn off the electric heater and limit the power of the wind turbine.

The supply of water and heating it to the required temperature should be restored between waterings. Since this period is several times longer than the period of drinking, the throughput of the water supply system and the valve-float mechanism, as well as the power of the wind generator and electric heater, will be required several times less than if the direct supply of water to the drinking bowl with its simultaneous heating to the required temperature.

All this in aggregate and contributes to the improvement of the operational characteristics of the claimed group car drinkers, allowing with less energy costs to ensure the supply of water of the required temperature in the required amount, regardless of the intensity of consumption by animals.
