Description

Solar water heater

Technical Field

The utility model relates to the technical field of solar water heaters.

Background

The vacuum tube type solar water heater irradiates solar energy to a coating of a vacuum heat collecting tube, the coating converts the solar energy into heat energy, the heat energy is transferred to water in the heat collecting tube, the water temperature is increased, the density is reduced, the hot water moves upwards and flows into the upper part of a water tank, the specific gravity of cold water in the lower part of the water tank is large and falls, and the cold water enters the heat collecting tube to form self circulation. Because the solar heat collecting tube is placed outdoors for a long time, dust is easy to accumulate on the surface of the solar heat collecting tube after long-time use, and because most solar heat collecting tube is installed on the roof, manual cleaning is inconvenient, and heating efficiency is affected.

In order to solve the technical problems, the technical scheme of the utility model is that the solar water heater comprises a water tank, a plurality of vacuum heat collecting pipes and a bracket; the upper surfaces of the vacuum heat collecting pipes are respectively provided with an arc-shaped cleaning strip in a sliding manner; a plurality of cleaning bars are arranged on the cleaning rod; and a driving assembly for driving the cleaning rod to move along the axial direction of the evacuated collector tube is arranged on the bracket.

Further, the included angle of the cleaning strip is 180-240 degrees.

Further, the driving assembly comprises a motor arranged on the bracket and a screw rod rotatably arranged on the bracket; one end of the screw rod is connected with the output end of the motor; the screw is connected with a nut through threads; the cleaning rod is fixedly connected with the upper end face of the nut.

Further, a limiting rod is fixedly arranged on one side, far away from the screw rod, of the bracket; a sliding block is arranged on the limiting rod in a sliding manner; one end of the cleaning rod, which is far away from the nut, is connected with the upper end face of the sliding block.

Further, the cleaning bar is detachably connected with the cleaning rod.

Further, the cleaning bar is in threaded connection with the cleaning rod.

The utility model has the beneficial effects that:

the cleaning rod is driven to move along the vacuum heat collecting pipe by controlling the driving assembly, so that the cleaning rod is driven to slide along the surface of the vacuum heat collecting pipe, and dust accumulated on the surface of the vacuum heat collecting pipe is cleaned, and the heating efficiency is improved.

Detailed Description

The following describes the embodiments of the present utility model further with reference to the drawings. The description of these embodiments is provided to assist understanding of the present utility model, but is not intended to limit the present utility model. In addition, the technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

Examples

A solar water heater, as shown in figures 1-3, comprises a water tank 1, a plurality of evacuated collector tubes 2 and a bracket 3; the upper surfaces of the vacuum heat collecting pipes 2 are respectively provided with an arc-shaped cleaning strip 5 in a sliding manner; a plurality of cleaning bars 5 are arranged on the cleaning rod 6; the bracket 3 is provided with a driving component 4 for driving the cleaning rod 6 to move along the axial direction of the evacuated collector tube 2.

The cleaning rod 6 is driven to move along the evacuated collector tube 2 by controlling the driving component, so that the cleaning strip 5 is driven to slide along the surface of the evacuated collector tube 2, and dust accumulated on the surface of the evacuated collector tube 2 is cleaned, so that the heating efficiency is improved.

Specifically, in order to increase the cleaning area, the included angle of the cleaning strip 5 is 180-240 degrees.

Specifically, the driving assembly 4 includes a motor 401 mounted on the bracket 3, and a screw 402 rotatably mounted on the bracket 3; one end of the screw 402 is connected with the output end of the motor 401; a nut 403 is connected to the screw 402 in a threaded manner; the cleaning rod 6 is fixedly connected with the upper end surface of the nut 403. The motor 401 is controlled to rotate positively and negatively, the screw 402 is driven to rotate, the nut 403 is driven to reciprocate on the screw 402, and accordingly the cleaning rod 6 and the cleaning bar 5 are driven to reciprocate, and dust is cleaned.

Specifically, a limiting rod 404 is fixedly installed on one side of the bracket 3 far away from the screw 402; a slide block 405 is slidably arranged on the limiting rod 404; the end of the cleaning rod 6 remote from the nut 403 is connected to the upper end face of the slider 405. The sliding block 405 cooperates with the stop lever 404 to perform a guiding function on one hand and to perform a function of limiting the rotation of the cleaning lever 404 on the other hand.
