Description
Technical field
The utility model relates to a kind of improved rubber dam.
Background technology
Chinese patent ZL201220004640.6 discloses a kind of rubber dam, it is characterized in that: dam bag is provided with enhancement Layer.When this rubber dam is retained water running, enhancement Layer is bearing in outside dam bag, bears the pressure that dam bag transmits.Enhancement Layer bears the pressure that dam bag transmits, and dam bag has been play a part to strengthen.But it also exists such problem: when rubber dam is retained water running, enhancement Layer bears the size of the pressure that dam bag transmits, and the size of pressure between the dam bag of rubber dam and enhancement Layer, is the definite value being designed to.When rubber dam is retained water running, between the dam bag of rubber dam and enhancement Layer, pressure has departed from design load, or is that the pressure that dam bag bears has surpassed design load, or is that the pressure that enhancement Layer bears has surpassed design load.The pressure that dam bag, enhancement Layer bear has surpassed design load, and the application life of rubber dam is all directly influenced, and even can sharply shorten the application life of rubber dam.In prior art, the analog electrical signal that existing kinds of schemes produces sensor converts data signal to, and this data signal demonstrates the data that people need after processing again.Thereby pressure signal can be exported easily in real time between the dam bag of rubber dam and enhancement Layer, rubber dam running status just can obtain Real-Time Monitoring easily.
Summary of the invention
The purpose of this utility model is that a kind of improved rubber dam will be provided, this rubber dam is retained in water running, the dam bag of rubber dam and the pressure signal between enhancement Layer can be exported easily in real time, and rubber dam running status can obtain Real-Time Monitoring, and can be guaranteed the application life of rubber dam.
The purpose of this utility model is achieved in that a kind of improved rubber dam, comprises dam bag, enhancement Layer, it is characterized in that one or more pressure sensors are arranged between the dam bag and enhancement Layer of rubber dam.
Its additional technical feature:
Described pressure sensor is connected with pressure-display device by sensor signal transmission line;
In described pressure sensor, be provided with amplifier;
Described sensor signal lines is through in steel pipe, is embedded in underground soil layer, and steel pipe is zinc-plated;
The incoming line place of described steel pipe establishes waterproof junction box;
In described pressure-display device, be provided with amplifier, A/D converter and microprocessor (CPU);
When rubber dam is retained water running, the size of the pressure that the pressure sensor arranging between dam bag and enhancement Layer is subject to is the size of the pressure between dam bag and enhancement Layer.Pressure sensor pressurized, produces and the proportional signal of telecommunication of the pressure being subject to, and this signal of telecommunication can be exported easily in real time by its output line.The described signal of telecommunication, by sensor signal transmission line input pressure display unit, demonstrates pressure data, and rubber dam running status is monitored.When amplifier being set in pressure sensor by the proportional signal of telecommunication amplification of the pressure to being subject to of pressure sensor generation or in described waterproof junction box, transmitted signal having been done to amplification, through the signal of telecommunication having amplified, can realize longer-distance conveying, pressure-display device can be far away apart from the distance that the pressure tap of pressure sensor is set.Thereby, having reached this rubber dam and retained in water running, the dam bag of rubber dam and the pressure signal between enhancement Layer can be exported easily in real time, and rubber dam running status can obtain Real-Time Monitoring easily, and the application life of rubber dam can guaranteed object.
The utility model has the advantages that: the utility model is only that one or more pressure sensors are arranged between the dam bag and enhancement Layer of rubber dam, so simple in structure, cost is low; Between the dam bag of rubber dam and enhancement Layer, pressure signal can be exported easily in real time, and between Real-time Obtaining dam bag and enhancement Layer, pressure signal is easy; Described signal of telecommunication input pressure display unit, demonstrates pressure data, and rubber dam running status is monitored; When arranging in pressure sensor that amplifier has amplified the signal of telecommunication or in described waterproof junction box, transmitted signal having been done to amplification, through the signal of telecommunication having amplified, can realize longer-distance conveying, pressure-display device can be far away apart from the distance that the pressure tap of pressure sensor is set.Rubber dam is retained in water running, between Real-time Obtaining dam bag and enhancement Layer, pressure signal is easy, can monitor easily the dam bag of rubber dam and the pressure between enhancement Layer, monitor easily rubber dam operation conditions, this is just conducive to rubber dam and runs on design point, makes to reach its application life design load.
