Description

Water invasion alarm

Technical Field

The utility model relates to a water invasion alarm.

Background

With the increasing importance of each city on city pollution discharge management, in order to prevent industrial or domestic sewage from being stolen or leaked into a rainwater pipeline, the interior of the rainwater pipeline in the polluted city needs to be detected, the existing mode is usually set at a water outlet for detection, but the pollution source cannot be conveniently traced, a detection contact type water logging detector is used for detecting by utilizing a liquid conductive index, and a two-pole probe is insulated by air when normal; the probe is conducted in a water immersion state, and the sensor outputs a main contact signal, and the main control chip determines the state and makes processing feedback by calculating the magnetic field change to accurately conduct the index.

SUMMERY OF THE UTILITY MODEL

The utility model improves the problems, namely the technical problem to be solved by the utility model is that the existing urban pipe network is easy to discharge sewage.

The specific embodiment of the utility model is as follows: the utility model provides an alarm is invaded to water, includes the shell body, the inner chamber of shell body is separated and is formed the battery chamber that upper portion is used for depositing the battery and the response chamber of lower part, the response intracavity is fixed with contact water logging detector, the bottom of shell body seals and has the inlet and outlet hole with response chamber intercommunication.

Furthermore, a hanging ring is fixed at the top of the outer shell.

Furthermore, the water inlet and outlet holes are positioned on two sides and the bottom surface of the lower part of the outer shell.

Further, the bottom of the outer shell is conical.

Further, the surface of the outer shell is provided with a convex anti-collision rubber column.

Furthermore, the lifting ring is hung below the well lid through a lifting rope.

Compared with the prior art, the utility model has the following beneficial effects: the utility model can conveniently place the water invasion alarm into the drainage pipeline to be detected, and can detect the urban drainage pipeline by being arranged under the rainwater well, thereby being convenient to trace the source of the polluted water source.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-2, the water intrusion alarm comprises an outer shell 10, wherein an inner cavity of the outer shell is divided into a battery cavity 110, the upper portion of which is used for storing a battery, and a sensing cavity 120, the lower portion of which is used for storing a battery, the sensing cavity is internally fixed with a contact type water intrusion detector, and the bottom of the outer shell is closed and is provided with a water inlet and outlet hole 20 communicated with the sensing cavity.

In this embodiment, a hanging ring 130 is fixed on the top of the outer casing.

In this embodiment, the water inlet and outlet holes are located on two sides and the bottom of the lower portion of the outer casing 10.

During operation, rings 130 hang in rainwater well lid 100 below through lifting rope 30, and rainwater drainage pipe 101 in the city is generally laid under rainwater well lid, and normal no rainwater or normal water level's the condition offal can not get into in response chamber 120 or be in the electrically conductive index of the drainage in response chamber 120 when raining and be in predetermineeing normal level, if appear stealing and arrange then the water level rises, and the contact water logging detector who triggers in response chamber 120 behind the entering response chamber judges quality of water.

The water inlet and outlet holes 20 are located on two sides and the bottom of the lower part of the outer shell to ensure the penetration of silt.

The battery and associated sensor chip of the outer housing must be waterproof, with the top of the outer housing being a sealing surface.

As shown in fig. 3 to 4, in the second embodiment, in order to avoid collision between the outer shell and the well wall in the hanging process, a raised anti-collision rubber column 40 is arranged on the surface of the outer shell 10, so as to achieve an anti-collision effect.

In the third embodiment, as shown in fig. 5, the bottom of the outer shell is conical, and the middle of the outer shell is provided with a water inlet and outlet hole 20 to facilitate the discharge of silt from the bottom of the outer shell.

If the utility model discloses or relates to parts or structures which are fixedly connected to each other, the fixedly connected parts can be understood as follows, unless otherwise stated: a detachable fixed connection (for example using bolts or screws) is also understood as: non-detachable fixed connections (e.g. riveting, welding), but of course, fixed connections to each other may also be replaced by one-piece structures (e.g. manufactured integrally using a casting process) (unless it is obviously impossible to use an integral forming process).

In addition, terms used in any technical solutions disclosed in the present invention to indicate positional relationships or shapes include approximate, similar or approximate states or shapes unless otherwise stated.

Any part provided by the utility model can be assembled by a plurality of independent components or can be manufactured by an integral forming process.

Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present invention and not to limit the same; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the utility model or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the utility model as defined by the appended claims.
