RU2468576C1 - Automatic drinking bowl for rabbits and other small animals, preferably for winter time - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and may be used to give water to small animals. The automatic drinking bowl for small animals and birds comprises a reservoir (1) with water, a heat insulation material (2) of the reservoir and a heater (5). Inside the reservoir (1) there is a watering tube (3) with a nipple valve (10) at the end. The watering tube (3) stretches outside from the reservoir (1) via a sealant (4). The heater (5) is installed inside the watering tube (3) along its entire length and is arranged as posistor, automatically maintaining the specified temperature. The heater (5) is connected to a source of supply (9). A drain hole (11) for water supply is arranged above the sealant (4). The heat insulation material (2) has a cellular structure.

EFFECT: provision of water to animals under minus temperature of ambient air and increased comfort of device usage.

Description

The invention relates to the field of agriculture, is intended for use in animal husbandry for drinking small animals, rabbits, fur animals, as well as birds contained in unheated buildings at an ambient temperature below zero.

An automatic device for drinking is known, see patent RU 1817677 A1, in which water flows through a drinking tube having a nipple valve. By clicking on the nipple, the animal receives water.

An automatic device for drinking is known, see patent RU 13530 U1, in which water flows through a drinking tube having a nipple valve. When the animal clicks on the nipple, water enters the bowl from which the animal drinks.

A disadvantage of the known devices is the inability to drink animals at sub-zero air temperatures in unheated rooms.

To drink in cold weather, the temperature of the water in the tank and bowl is maintained above zero degrees Celsius to prevent it from freezing, and the tank and bowl are thermally insulated. For example, devices in which a tank, a canister with a capacity of 5 liters, and a bowl with an electric heater are placed in a thermally insulated box - a thermos. Only the part of the bowl protruding from the thermos from which the animals drink (Mikhailov I.N. - What does the rabbit need. Manual for rabbit breeding. ITF, Stalker, Leningrad, 1991, pp. 30-31).

The disadvantage of such designs is a significant consumption of thermal energy due to the need to maintain a positive temperature in the entire volume of water in the tank and because of the large surface area of the thermos transfer.

Known car drinker for rabbits, containing mounted on a support tank with water, a tank heater and a heater used in the winter in unheated rooms, RU 2268585 C1. It is made vacuum and accordingly has a bowl, into which water comes from the tank. The heater is partially located in the neck of the tank.

This solution has the same drawback as the above, high energy consumption, because at the same time it is necessary to warm both the bowl and the container. In addition, the electronic temperature controller used in the above drinkers is quite expensive, it requires a stable power supply for its operation and is the most unreliable part of the design.

The objective of the invention is to reduce energy consumption to provide animals with water at sub-zero ambient temperatures, as well as ensuring ease of use.

The technical result is achieved by the fact that the drinker for rabbits and other small animals contains a container with water, a container heater and a heater. A drinking tube is installed inside the container, passing outward from the container through a seal, at the end of which there is a nipple valve, the heater is installed inside the drinking tube along its entire length and is made of a posistor and automatically maintains the set temperature, while it is connected to a power source. And the drain hole for the water supply is located above the seal. The insulation has a honeycomb design.

The invention is illustrated in the drawing.

The following positions are used in the drawing:

1 - water tank

2 - insulation

3- drinking tube

4 - a sealant

5 - posistor heater

6 - support in the form of a base plate

7 - bottom cover with insulation

8 - top cover with insulation

9 - power source

10 - nipple valve

11 - drain hole.

The auto-drinker works as follows. Open the top cover and fill with water. Unlike vacuum drinking bowls, you do not need to pull out the container and topple it full, which increases the convenience in its use. Close the lid and turn on the heater. Water enters the water tube through the drain hole, which is located above the seal. This prevents debris from falling into the feeding tube and interfering with the operation of the nipple valve. The posistor heater is self-adjusting and it automatically maintains a temperature of around + 10 ° C at the end of the drinking tube. At this temperature, the valve does not freeze even in severe frosts, tests have shown that even at -33 ° C. An unstabilized AC or DC power supply can be used to power a posistor heater. Power surges of the supply voltage have practically no effect on the power of the posistor heater. Since there is no drinking bowl, it does not need to be heated and waste energy. There is also no need to wash it. If in severe frosts the water in the tank freezes, then ice will form outside, i.e. actually get a thermos, because ice will be an additional thermal insulator. The insulation is expediently made of cellular material.
