Abstract
Description
Technical Field
[0001] The utility model relates to an alarm device, in particular to an alarm device for detecting the contact between a tension wire and an object. Background Art
[0002] The tension wire device is a measuring device that tightens a steel wire between the base points at both ends of a dam body as a reference line, and then measures the deviation values of each measuring point on the dam body relative to the reference line to calculate the displacement.
[0003] As Figure 1 shown, the tension wire device mainly includes a fixed-end assembly, a measuring wire, a measuring point assembly, a floating support assembly, a measuring and reading instrument, a protection tube and a bracket, and a tensioning-end assembly. Among them, the fixed-end assembly includes a winch made of metal, a positioning card, a protection box and a mounting plate; the measuring wire is a high-strength stainless steel wire; the measuring point assembly includes a reading scale made of metal, a measuring and reading instrument mounting chassis and a protection box; the floating support assembly can be combined with the measuring point assembly, and it includes a floating box, a floating ship and a protection box made of metal and a floating liquid arranged inside the floating box; the measuring and reading instrument is a manual measuring and reading device or a telemetry tension wire instrument; the protection tube is a stainless steel tube; the bracket is made of stainless steel; the tensioning-end assembly is made of a pulley, a positioning card, a weight, a protection box and a mounting base plate made of stainless steel.
[0004] In the normal use state, the measuring wire (i.e., the tension wire) will not touch components such as the protection box, the reading scale, the floating box and the protection tube. However, due to the volatilization of the floating liquid in the floating box, the floating ship moves downward, which drives the tension wire to move downward and touch the floating box or the protection box. Sometimes, due to the influence of external force factors such as earthquakes, the tension wire will shift and touch components such as the protection box, the reading scale and the protection tube. Even, there will be a phenomenon that animals such as mice bite off the tension wire. The above factors will cause the measurement of the tension wire device to deviate and cannot truly reflect the deviation value.
[0005] Currently, there is a lack of an alarm device for detecting the contact between a tension wire and an object. After a failure occurs, it cannot be timely feedback to the staff. The staff needs to check whether there is a failure at each position irregularly. Usually, the entire length of the dam body is relatively long, and it is often time-consuming and laborious to check one by one manually. Summary of the Utility Model
[0006] The technical problem to be solved by the utility model is to provide an alarm device for detecting the contact between a tension wire and an object, which is used to detect whether the tension wire contacts other components, and will emit an alarm after contact, accurately informing the staff of the fault location.
[0007] To solve the above technical problems, the utility model adopts the following technical solutions:
[0008] An alarm device for detecting the contact between a tension wire and an object, including a tension wire device, is characterized in that the alarm device further includes a power source, a first wire, a second wire, and an alarm; the number of the alarms is greater than or equal to the sum of the number of components of the tension wire device and the number of protection pipes; at least one alarm is connected to a component of a tension wire device, and one of the components is connected to the negative pole of the power supply end of the alarm through a first wire, the positive pole of the power supply end of the alarm is connected to the positive pole of the power source through a first wire, and each component in the component is connected in series through a second wire; at least one alarm is connected to a protection pipe, the protection pipe is connected to the negative pole of the power supply end of the alarm through a first wire, and the positive pole of the power supply end of the alarm is connected to the positive pole of the power source through a first wire; the part of the tension wire in the tension wire device located at the force application end component is connected to the negative pole of the power source through a first wire; both the alarm and the power source are arranged in the workshop.
[0009] The beneficial effects of the present utility model are as follows:
[0010] For the alarm device for detecting the contact between a tension wire and an object provided by the present utility model, since almost all the components in the tension wire device and the protection pipes are made of metal, by utilizing the electrical conductivity of the metal, when the tension wire touches a component in the component or the protection pipe, the first wire, the second wire, and the tension wire will be electrically connected to each other. For example, when the tension wire contacts a component in the component, then the first wire, the second wire, and the tension wire are electrically connected to each other, and the alarm connected to the component will give an alarm; when the tension wire contacts the protection pipe, then the first wire and the tension wire are electrically connected to each other, and the alarm connected to the protection pipe will give an alarm. Moreover, both the alarm and the power source are arranged in the workshop, so that the staff in the workshop can timely check the location where the fault occurs according to the alarm of the alarm, which can reduce the frequency of the staff going to the site to check the fault, improve the work efficiency, and also reduce the workload.

Detailed Embodiment
[0014] The present utility model will be described below in conjunction with the accompanying drawings. The specific embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not intended to limit the present utility model. Without departing from the spirit of the design of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope of the present utility model.
[0015] As Figure 1 and Figure 2 shown, the alarm device for detecting the contact between the tension wire and the object in this embodiment includes a tension wire device, a power source 9, a first wire 10, a second wire 11, and an alarm 12.
[0016] Among them, the number of alarms 12 is greater than or equal to the sum of the number of components of the tension wire device and the number of protection tubes 6. The alarm 12 in this embodiment is a flashing light, and different flashing lights can adopt different colors. The alarms 12 are represented by L1, L2... Ln in the figure.
[0017] At least one alarm 12 is connected to a component of a tension wire device. One of the components is connected to the negative pole of the power supply terminal of the alarm 12 through the first wire 10. The positive pole of the power supply of this alarm 12 is connected to the positive pole of the power source 9 through the first wire 10. Each component in the component is connected in series through the second wire 11. Taking the measuring point component 4 as an example for illustration, one end of a first wire 10 can be connected to the side wall of the protection box, and the other end of this first wire 10 is connected to the negative pole of the power supply terminal of the alarm 12. The positive pole of the power supply of this alarm 12 is connected to the positive pole of the power source 9 through another first wire 10; then the reading scale, the measuring instrument mounting chassis, and the protection box in the measuring point component 4 are connected in series through multiple second wires 12.
[0018] At least one alarm 12 is connected to one protection tube 6. The protection tube is connected to the negative pole of the power supply terminal of the alarm 12 through the first wire 10. The positive pole of the power supply of the alarm 12 is connected to the positive pole of the power source 9 through the first wire 10.
[0019] The part of the tension wire 2 in the tension wire device located in the loading end component 8 is connected to the negative pole of the power source 9 through a first wire 10, that is, the part of the tension wire 2 between the weight and the pulley is connected to the negative pole of the power source 9 through a first wire 10. In addition, a protection resistor R is connected between the tension wire 2 and the positive pole of the power source 9. One end of the protection resistor R is connected to the tension wire 2 through the first wire 10, and the other end of the protection resistor R is connected to the negative pole of the power source 9 through the first wire 10.
[0020] A plurality of contact points are provided on the tension wire 2, as well as on each component and the protection tube 6. Any contact point on the tension wire 2 and any contact point on each component or the protection tube 6 can conduct the circuit.
[0021] To facilitate viewing of the alarm information, both the alarm 12 and the power supply 9 are arranged in the factory building, and it is necessary to mark the components or the protection pipe 6 corresponding to the connection of the alarm 12 beside the alarm 12.
[0022] For the alarm device for detecting the contact between the tension wire and the object in this embodiment, since almost all the components and the protection pipe 6 in the tension wire device are made of metal, using the electrical conductivity of the metal, when the tension wire 2 touches the component or the protection pipe 6, the first wire 10, the second wire 11 and the tension wire 2 will be electrically connected to each other. For example, when the tension wire 2 contacts the component, then the first wire 10, the second wire 11 and the tension wire 2 are electrically connected to each other, and the alarm 12 connected to the component issues an alarm. Taking the floating component 5 as an example, when the floating liquid volatilizes and causes the floating ship to move downward, which drives the tension wire 2 to move downward and touch the floating box or the protection box. At this time, the first wire 10 connected to the floating component 5, the second wire 12 connected to each component in the component, and the tension wire 2 will be electrically connected, then the first wire 10, the second wire 11, the power supply 9 and the alarm 12 will form a loop, so that the alarm 12 can issue an alarm. When the tension wire 2 contacts the protection pipe 6, similarly, the first wire 10 and the tension wire 2 are electrically connected to each other, and the alarm 12 connected to the protection pipe 6 issues an alarm. Moreover, both the alarm 12 and the power supply 9 are arranged in the factory building, so that the staff can timely find out the location of the fault according to the alarm of the alarm 12 in the factory building, which can reduce the frequency of the staff going to the site to check the fault, improve the work efficiency and reduce the workload at the same time. Even if the tension wire 2 is bitten off by an animal, the bitten tension wire 2 may also contact the component or the protection pipe 6, then the corresponding alarm 12 will issue an alarm, thus reminding the staff that there is a fault at the corresponding location.
