In order to make the technical problem, technical solution and beneficial effects to be solved by the present invention more clearly understood, the following description is made in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
In the description of the present application, it is to be noted that: the fixed connection can be detachable fixed connection or integrated fixed connection; the terms "axial," "radial," and the like, refer to a positional relationship based on what is shown in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be considered limiting of the present application.
The utility model discloses the first embodiment provides a drainage is prevented suck-back and is put, can be used to supplementary drainage, is particularly useful for the air conditioner.
Referring to fig. 1 to 6, the structure of the drainage suck back prevention device includes the following structural components.
Water collection tank 1: the top of which is an open end and the bottom plate of which is provided with a water outlet 101.
In order to facilitate the installation of the drainage and suck-back prevention device, a circumferential mounting plate 102 is arranged along the top edge of the water collection tank 1, and the circumferential mounting plate 102 is bent towards the outside of the opening relative to the tank wall of the water collection tank 1.
In order to collect water flow conveniently, the water collecting tank 1 is conical, and one side where the water outlet 101 is located is a conical contraction end.
Referring to fig. 3, in the present embodiment, the water collection tank 1 is in a quadrangular frustum pyramid shape with four surfaces, and the inside thereof is a hollow structure. The water outlet 101 is arranged at the contraction end of the quadrangular frustum and is downwards arranged in the use state; the drainage water flows into the water collecting tank 1 through the flaring end of the rectangular pyramid.
And (3) plug 2: the plug-in mounting is arranged at the water outlet 101 of the water collecting tank, can move relative to the water outlet and can seal the water outlet 101 after being plugged in.
A guide sleeve 3: is arranged on the bottom plate of the water collecting tank 1 and is positioned outside the water collecting tank 1; the plug 2 and the water outlet 101 are both positioned in a guide sleeve cavity formed by the guide sleeve 3. In this embodiment, the guide sleeve 3 is a cylindrical hollow sleeve, the radial width of which is greater than the width of the water outlet 101, and the guide sleeve can be fixedly installed below the groove bottom of the water collecting tank 1 by welding and other manners.
The fastening plate 4: is arranged in the cavity of the guide sleeve. The shape of the fastening plate 4 needs to be designed to match the shape of the inside of the cavity of the guide sleeve 3 so that it can be installed inside the cavity of the guide sleeve 3.
The elastic member 5: is positioned between the plug 2 and the fastening plate 4. The embodiment uses a spring.
In a normal state, the water outlet 101 is closed. The length of the elastic piece 5 can be adjusted, and the plug 2 can be upwards pushed tightly under the action of elastic force. Because the plug 2 is connected with the water outlet 101 in a non-fixed mode, when the water flow in the water collecting tank 1 is increased, the plug 2 moves downwards under the action of the gravity of the water, the elastic piece 5 is compressed, the water outlet 101 is opened, and the water flows out through the water outlet 101. When the water in the water collecting tank 1 flows out, the water in the water collecting tank 1 is reduced, and when the gravity action of the water is not enough to impact the plug 2, the plug 2 seals the water outlet 101 under the restoring force of the elastic element.
Referring to fig. 4, in order to achieve a better cooperation between the plug 2 and the water outlet 101, in some embodiments of the present invention, the plug 2 includes an insertion head 201, the insertion head 201 is tapered, and the tapered end thereof is inserted into the water outlet 101. This configuration further facilitates the insertion of the plug 2 into the outlet 101.
The plug 2 further comprises a plug seat 202, which is an integral structure with the plug, and the radial width of the plug seat is larger than that of the water outlet.
Furthermore, after water flows out of the water outlet 101, the water enters a space formed by the guide sleeve 3 and the fastening plate 4, and in order to avoid water accumulation in the space, the following drainage structure is further designed:
the drainage grooves 203 are formed along the peripheral wall of the plug seat 202, and the drainage grooves 203 are formed along the height direction of the plug seat. The water flow may be directed through the drain tank 203.
Water outlet holes 301 are provided along the outer peripheral wall of the guide sleeve 3, and the number of the water outlet holes is not limited, but 4 in this embodiment.
The fastening plate 4 is provided with water outlet holes 401, the number of which is not limited, and the number of the water outlet holes is 4 in the embodiment.
Above drainage tank 203, apopore 301, 401 all play the effect of drainage, avoid ponding to cross pile up in the space between guide pin bushing and mounting plate 4.
In order to solve the problem of installation between the fastening plate 4 and the guide sleeve 3:
referring to fig. 5 and 6, in some embodiments of the present invention, the fastening plate 4 has external threads 402 along the outer peripheral wall of the fastening plate 4 and internal threads 302 along the inner wall of the guide sleeve, and the fastening plate 4 is screwed to the guide sleeve 5. The distance between the fastening plate 4 and the water collecting tank 1 is also conveniently adjusted by the structure, so that the pretightening force of the elastic piece 5 is adjusted, and the integral drainage capacity of the drainage anti-suck-back device can be adjusted.
The utility model discloses the second embodiment further provides a train air conditioning system, prevent suck-back device including the drainage that the first embodiment provided.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
