The invention discloses a method for attracting fish by raising the temperature of a fishway, comprising the steps of: S1: opening a flow control valve, and flowing hot water from a hot water source into a water injection pipe; S2: after the water injection pipe is filled with hot water, under the action of water pressure , hot water enters into the gear-like water injection chamber through the water injection branch pipe; S3: Driven by the external motor, the gear-like water injection chamber as the driving wheel drives the gear-like water injection chamber as the driven wheel to rotate through the chain, and the gear-like water injection chamber as the driven wheel rotates. With the rotation of the water injection chamber, the angle between the eccentric water injection hole on the gear-like water injection chamber and the vertical direction is constantly changing, and the hot water injected in the gear-like water injection chamber is supplied to the fishway through the water injection hole, thereby realizing the temperature of the water flow in the fishway. Uniform temperature rise; S4: The temperature sensor in the fishway and the temperature sensor in the river respectively sense the raised temperature in the fishway and the unincreased temperature in the river; S5: The intelligent temperature control system controls the flow rate according to the temperature rise range of the fishway. The opening or closing of the hot water channel of the control valve.

The invention discloses a temperature-controllable dry and wet-open and closed integrated cooling tower system which comprises a cooling tower, an automatic controller, an open cooling tower water inlet pipeline, a closed cooling tower water inlet pipeline, a heat release equipment cooling water return pipeline, an open cooling tower water outlet pipeline, a closed cooling tower water outlet pipeline, and a heat release equipment cooling water supply pipeline, wherein the automatic controller is used for controlling running of a variable frequency motor of the cooling tower and starting or stopping of a circulating water pump; and the automatic controller is also used for controlling the conduction paths of the pipelines by controlling a three-way reversing valve. According to the integrated cooling tower system, surrounding air can be fully utilized to perform a cooling operation in summer, the high-efficiency cooling effect of cooling water is achieved on the basis of effectively preventing frostbite in winter, open and closed heat exchange modes can be switched from one another and can be also combined for operation, and the high-efficiency heat exchange of the cooling tower is achieved.

The invention provides an insulating electric kettle. The kettle comprises a kettle body, heating elements, a water boiling heating circuit and an insulation heating circuit, wherein the heating elements are connected in the water boiling heating circuit in series; the insulation heating circuit comprises a kick type temperature controller and a PCB board for controlling power of the heating elements, which are connected in series; and the heating elements are simultaneously connected in the insulation heating circuit in series, so that heating elements simultaneously have functions of water boiling heating and insulating. The kettle reduces power when a heating tube works by utilizing the characteristic of the PCB board, or power reduction on the PCB board can be set into an adjustable mode, thereby realizing insulation of water in different capacities. The kick type temperature controller is an automatic reset temperature controller, and the operating temperature of the controller can be set according to requirement of different users so as to realize controllable water temperature. The insulating electric kettle has the advantages of simple and reasonable structure, high heat utilization rate, low cost, wide application range (such as households, hotels, tea houses and the like), and is applicable to mass production.

The invention relates to a gutta-percha separation device which comprises a rack, wherein a water tank is arranged on the rack and extends downwards from the interior of an opening formed in the upper end of the rack; the upper end of the side wall of the water tank is fixedly connected with the rack; a separation barrel is horizontally arranged above the water tank and comprises a separation barrel body and a supporting shaft which is fixedly connected with the separation barrel body and is horizontally arranged; separation holes are formed in the side wall of the separation barrel body; two ends of the supporting shaft are respectively supported in two bearing seats on the rack by virtue of bearings; the two bearing seats are respectively arranged at two sides of the water tank; stirring blades are arranged on the inner wall of the separation barrel body; and a driving device used for driving the separation barrel to rotate is arranged at one side of the rack. According to the device, non-rubber materials in the bark of eucommia ulmoides in the separation barrel body are washed away by virtue of the rotation of the separation barrel in the water tank, so that the conception is ingenious, the washing and separating effect is good, and the damage to gutta-percha is completely avoided. In addition, the device is clean and environment-friendly.
