Description

Technical Field

[0001] The present application relates to the field of monitoring technology, and in particular to a water leakage and seepage alarm device. Background Art

[0002] In recent years, the demand for hemodialysis treatment has grown year by year, and the scale of blood purification centers has become increasingly larger. The number of dialysis machines has also increased from a few to dozens, or even one or two hundred. The frequency of dialysis machine use has also increased from two shifts per day to three, or even four, and they are almost always running at full capacity. With the increasing number of dialysis machines and their increasing frequency of use, the time available for dialysis machine maintenance has also decreased, leading to safety hazards and a significant increase in the maintenance burden on engineering personnel. Dialysis machines are structurally divided into a waterway and an electrical circuit. Currently, most major dialysis machine manufacturers determine leaks by monitoring the pressure within the waterway pipes, which has poor accuracy and is unable to detect trace amounts of leaking water. The liquid in the dialysis machine contains components such as magnesium carbonate and calcium carbonate. When a leak occurs, crystals form. If this is not detected for a long time, it can damage other components, resulting in a significant safety hazard. Summary of the Invention

[0003] The present invention mainly addresses the above problems and proposes a water leakage and seepage alarm device, the purpose of which is to monitor objects that may leak water and liquid and reduce the burden of inspection and maintenance.

[0004] To achieve the above-mentioned objectives, the present invention provides a water leakage and seepage alarm device, including a conductive clamp and a conductive tape, wherein the conductive tape includes two groups of conductive layers, liquid-absorbing cotton and a liquid-conducting cloth strip, wherein the two groups of conductive layers are arranged on the liquid-conducting cloth strip at intervals from each other, and the two groups of conductive layers respectively have A contacts and B contacts, and the conductive clamp is used to match and contact with the A contacts and the B contacts; the liquid-absorbing cotton covers the two groups of conductive layers and is in contact with the two groups of conductive layers.

[0005] Furthermore, the material constituting the A contact and the B contact is one or more of conductive gel and graphene.

[0006] Furthermore, the surface of the liquid-conducting fabric strip is evenly covered with air vents.

[0007] Furthermore, both sides of the liquid-conducting cloth strip are provided with glue bonding parts or mutually bonded fleece surfaces and hook surfaces.

[0008] Furthermore, the conductive clamp includes a first clamp body and a second clamp body arranged upper and lower, and the first clamp body and the second clamp body are connected as a whole by a pivot, and the pivot is also provided with a torsion spring to provide a restoring force to make the upper clamping part of the first clamp body and the lower clamping part of the second clamp body close together, and the upper clamping part is provided with conductive contacts respectively connected to the A contact and the B contact, and the conductive contacts are electrically connected to the wire.

[0009] Furthermore, the conductive clamp also includes an auxiliary clamping member, which is configured on the upper clamping part and includes an auxiliary clamp for increasing the contact force between the conductive contact and the A contact and the B contact in the clamped conductive tape. The conductive contact is configured on the end face of the auxiliary clamp, and an opening is provided on the first clamp body, and the first clamp body is provided with a spring for driving the auxiliary clamp part to extend out of the opening.

[0021] The present invention will be described in detail below with reference to the accompanying drawings, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a central component. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] The water leakage and seepage alarm device of the present application is applicable to any application scenario that requires monitoring water leakage to meet various and complex needs. The present invention provides users with a convenient monitoring point through the water leakage and seepage alarm device, helping users to easily point out the problem of the instrument and assist users in better inspection and maintenance.

[0025] The technical solution of the present disclosure will be described below by taking a water leakage and seepage alarm device disclosed in this application as an example.

[0026] According to an example of the present disclosure, Figure 1-Figure 5It can be seen that the water leakage and seepage alarm device shown includes a conductive clamp 1 and a conductive tape 2. The conductive tape 2 includes two groups of conductive layers 21, liquid-absorbing cotton 22 and a liquid-conducting cloth strip 23. The two groups of conductive layers 21 are arranged at intervals from each other and are located on the front side of the liquid-conducting cloth strip 23. One end of the two groups of conductive layers 21 respectively has an A contact 201 and a B contact 202. The contact material can be composed of conductive materials such as conductive gel, graphene, and other metals. During use, the two independent and non-conductive contacts of the conductive clamp 1 are used to match the contact A 201 and the contact B 202; the liquid-absorbing cotton 22 covers the two sets of conductive layers 21 and is in contact with the two sets of conductive layers 21, that is, the conductive tape 2 is connected to the contact A 201 and the contact B 202 of the conductive layer 21 through the conductive clamp 1. When there is no leakage or seepage, the contact A 201 and the contact B 202 are equivalent to being suspended in the air; when leakage or seepage occurs, the liquid wets the liquid-absorbing cotton 22 and the liquid-conducting cloth strip 23, so that the contact A 201 and the contact B 202 at this position are connected to form a circuit, thereby triggering the microcontroller alarm.

[0027] In some embodiments, the liquid-guiding strip 23 is made of a soft material, and has glue bonding parts 24 or mutually bonded fleece and hook surfaces on both sides of its back. It can be installed on irregular objects that need to monitor water leakage and seepage. At the same time, since the liquid-guiding strip 23 occupies a small space, it can also be installed in gaps; the liquid-guiding strip 23 can also be made of coarse plain cloth, and the surface is evenly covered with air-venting holes 203, so that a small amount of water seepage can be evenly diffused and moistened, and the sensitivity is high; the liquid-guiding strip 23 and the liquid-absorbing cotton 22 have the physical properties of being conductive when wet and disconnected when dry, and can be reused.

[0028] The composition and connection relationship of the conductive clamp 1 will be described in detail below with reference to specific examples.

[0029] like Figure 3-Figure 5 As shown, the conductive clamp 1 includes a first clamp body 11 and a second clamp body 12 arranged upper and lower. The first clamp body 11 and the second clamp body 12 are connected as a whole by a pivot, and the pivot is also provided with a torsion spring to provide a restoring force to close the upper clamping part 110 of the first clamp body 11 and the lower clamping part 120 of the second clamp body 12 together. The operator applies force at the pressing part to expand the upper clamping part 110 of the first clamp body 11 and the lower clamping part 120 of the second clamp body 12 to insert the conductive tape 2 and then fix it, thereby improving the speed of installation and facilitating replacement.

[0030] The conductive clamp 1 is made of non-conductive materials such as plastic and rubber, and is divided into a first clamp body 11 and a second clamp body 12 arranged above and below. The second clamp body 12 is designed with a limit groove 1201 with a circular notch, so that the conductive tape can be accurately positioned when installed.

[0031] The conductive clamp 1 also includes an auxiliary clamping member 14, which is configured on the upper clamping portion 110 and includes an auxiliary clamping member 140 for increasing the contact strength between the conductive contact (not shown) and the A contact 201 and the B contact 202 in the clamped conductive tape 2. The conductive contact is configured on the end face of the auxiliary clamping member 140. The size of the auxiliary clamping member 140 is just adapted to the limiting groove 1201 of the U-shaped notch of the lower second clamping member 12. The first clamping member 11 is equipped with a double-core insulated wire 13, and the auxiliary clamping member 140 is provided with a contact with the wire 1 3, and are respectively connected to two conductive contacts slightly protruding on the end surface through the two electrical connection holes 1401. The two sets of conductive contacts are independent of each other and not conductive. An opening 1101 is formed on the first clamping body 11. The first clamping body 11 is provided with a spring 141 for driving the auxiliary clamping head 140 to partially extend out of the opening 1101, so that the two conductive contacts are exactly matched with the contact A 201 and the contact B 202 on the conductive tape. The auxiliary clamping head 140 is pre-tightened against the conductive tape 2 by the spring 141 to avoid poor contact.

[0032] In addition, a guide post 142 is provided in the first clamping body 11 , and a guide hole for the guide post 142 to pass through is provided in the auxiliary clamping head 140 , so as to install the auxiliary clamping head 140 and limit part of the freedom of the auxiliary clamping head 140 .

[0033] By reading and understanding the above specific embodiments, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to this specific embodiment. On the basis of the disclosed embodiments, those skilled in the art in the basic field can arbitrarily combine different technical features to achieve different technical solutions, which can also be combined with additional functions in different forms to form other technical solutions. Therefore, the scope of protection of this application is limited only by the scope of the appended claims.
