Description

Water distributing and collecting device
Technical Field
The invention belongs to the technical field of heating, and particularly relates to a water distributing and collecting device.
Background
In recent years, the adoption of geothermal heating in home decoration is gradually increased, and the application of a water collector matched with a geothermal heating system is more and more extensive. The water dividing and collecting device consists of a water dividing main pipe and a water collecting main pipe, wherein the water dividing main pipe is connected with a water supply pipe of a pipe network system and is mainly used for distributing hot water from the pipe network system to each room needing heating through a ground heating pipe buried under the floor. When the hot water flows in the ground heating pipe, the heat is transferred to the floor, and then the heat is radiated and transferred to the indoor through the floor. The other end of the ground heating pipe is connected with the water collecting main pipe of the water collecting and collecting device, and backwater with reduced temperature returns to the pipe network system through the water collecting main pipe after indoor heat dissipation to complete a cycle.
As shown in the intelligent water collecting and distributing device for floor heating pipe system disclosed in the chinese utility model patent with patent number ZL200920256878.6 (publication number CN201575533U), the water collecting and distributing device comprises two supports, a water dividing pipe and a water collecting pipe, and is characterized in that: the water distribution pipe and the water collection pipe are arranged between the two supports in parallel, a connecting pipeline is arranged between the water distribution pipe and the water collection pipe, a plurality of connectors are arranged on the water distribution pipe and the water collection pipe, a manual valve is arranged at each connector on the water distribution pipe, and an electric heating actuator is arranged at each connector on the water collection pipe. When in use, the flow of each branch is adjusted by adjusting the manual valve of the water distribution pipe; a thermistor is arranged in the electric heating actuator, and the opening and closing of the water collecting pipe are controlled by judging the temperature through a temperature sensor.
Therefore, the conventional water dividing and collecting device is troublesome to operate because the manual valve is adopted to control the opening and closing of a certain water way; or an electric heating actuator capable of being automatically controlled is adopted, but each branch water path is installed, so that the cost is higher.
Disclosure of Invention
The first technical problem to be solved by the invention is to provide a water dividing and collecting device without a control valve correspondingly arranged on each branch waterway, aiming at the current situation of the prior art.
The second technical problem to be solved by the invention is to provide a water dividing and collecting device which can automatically control the opening and closing of the branch water flow only by one set of driving mechanism aiming at the current situation of the prior art.
In order to solve the two technical problems, the technical scheme adopted by the invention is as follows: a water separating and collecting device is characterized by comprising
The shell is provided with a hollow inner cavity, and a first opening communicated with the inner cavity and at least two second openings arranged at intervals are arranged on the shell;

and the stepping driving mechanism acts on the cylinder and drives the cylinder to rotate step by step, so that the second through hole intermittently rotates to the corresponding second opening.
In order to allow different positions and different numbers of second openings to be opened for water flow, the number of second through holes of at least two groups of second through hole groups is different, so that different flow distribution conditions are adapted.
In order to enable the non-adjacent second openings on the shell to simultaneously pass through water flow, the centers of at least two second through holes in at least two groups of non-adjacent second through hole groups are distributed on the same straight line parallel to the axis of the cylinder body, so that the arrangement of the second through holes can meet the water flow on-off conditions of the second openings at different positions on the shell.
In order to improve the reliability of opening and closing the second opening on the shell when the barrel rotates, the second through hole groups are distributed on the barrel in at least three rows along the circumferential direction, the centers of the second through holes positioned in one row are distributed on the same straight line parallel to the axis of the barrel, the arrangement mode of the second through holes is reasonable in design, and the second through holes with small number are arranged on the barrel, so that all the shunting conditions of the second opening on the shell can be met; otherwise, the second through holes are distributed in disorder, so that the number of the second through holes is large, the volume and the surface area of the cylinder body are increased, and the second through holes meeting the shunting condition on the cylinder body cannot be rapidly and effectively rotated to the second opening.
In order to solve the problem that when the control accuracy of the moving stroke of the cylinder is not high, the position of the cylinder slightly deviates, the second through hole of the cylinder cannot be aligned with the second opening on the shell, and the aperture of the second through hole of the cylinder is larger than that of the second opening on the shell, so that the moving stroke of the cylinder is allowed to have certain position deviation.

In order to prevent the motor from rotating too fast and the rotation precision of the cylinder body from being difficult to control, the step driving mechanism further comprises a primary gear which is in driving connection with the output end of the motor, a circle of outer gear ring is formed on the edge of the crank along the circumferential direction, and the primary gear is directly meshed with the outer gear ring or indirectly meshed through at least one intermediate gear or is in chain transmission. Therefore, the speed is reduced through the meshing of the primary gear and the outer gear ring, the rotating speed of the motor is properly reduced, and the rotating precision of the cylinder is ensured.
