Abstract
The utility model provides an input type level sensor protection device suitable for monitoring of sewage water level, including sealed head of sensor safety cover, sensor centre gripping and isolation and detection atmoseal. The sensor safety cover passes through flange joint and sealed with the detection atmoseal. The sealed head of sensor centre gripping and isolation links together with the detection atmoseal in the sensor safety cover. Detecting the atmoseal and being half closed container, the lower part opening communicates with each other with sewage, and open at the top has the through -hole that can let gas pass through. Sensor safety cover upper portion is equipped with outer fiber tube hickey for the tubular metal resonator of connect protection sensor cable. This device is including the input type level sensor protection, reach when detecting the atmoseal when the sewage liquid level, the air sealed in the atmoseal and along with the rising of liquid level the compressed, under limited sewage liquid level height, the proportion of air compressed is limited, the liquid level in the atmoseal is ascending limited, input type level sensor not can with have the corruption, contain the sewage direct contact of silt, avoid the dirt of sensor to block up.
Description
Technical field
This utility model belongs to municipal administration safety devices field, level monitoring field.
Background technology
Urban drainage pipe network monitoring early warning and safety system needs to be monitored urban drainage pipe network water level.Water level monitoring method is a lot, and wherein throw-in type liquid level sensor is a kind of simple effective method.But owing to easily depositing containing a large amount of mud in sewage in urban drainage pipe network, needing periodically to clear up, sewage has certain corrosivity, has the possibility that there is damp.If directly putting in sewage by throw-in type liquid level sensor, the medium opening of the easy clogging sensor of mud causes its operation irregularity, or damages the sensor and cable being directly exposed in monitoring well because of artificial violence desilting.
Summary of the invention
The problem existed for prior art; the utility model proposes a kind of throw-in type liquid level sensor protection device being applicable to wastewater level monitoring; the protection to throw-in type liquid level sensor can be realized; avoid the corrosion of sewage; the blocking of mud, or the sensor and cable being directly exposed in monitoring well is damaged because of artificial violence desilting.
The technical solution of the utility model is as follows:
A kind of throw-in type liquid level sensor protection device being applicable to wastewater level monitoring, it includes sensor protective cover, sensor holders and isolating seal head and detection sealing gland.
Sensor protective cover and seals by Flange joint with detection sealing gland.Described sensor holders and isolating seal head, in sensor protective cover, are made up of fixing head and containment member, and fixing head links together with detection sealing gland, and link position containment member seals, and fixing head is used for gripping sensor.Detection sealing gland is a semienclosed container, and lower openings communicates with sewage, and detection sealing gland top has and gas can be allowed to pass through and enter the through hole of fixing head.Sensor protective cover top is provided with external fiber tube hickey, is used for connecting metal tube, protects sensor cable.
Including throw-in type liquid level sensor is protected by this device; when sewage level reaches to detect sealing gland; air is closed in sealing gland and is compressed with the rising of liquid level; the pressure of gas is with relevant relative to the liquid level of sealing gland end opening; under limited sewage level height, the ratio that air is compressed is limited, and the liquid level in sealing gland rises limited; throw-in type liquid level sensor directly will not contact with having the sewage that burn into contains silt, it is to avoid the dirt of sensor is blocked up.
Utility model has the advantage that
1. the pressure formed relative to the liquid level of sealing gland end opening by the air transmission closed in sealing gland, it is to avoid throw-in type liquid level sensor directly contacts with sewage, it is to avoid dirty block up.
2. by protective cover and external fiber tube hickey 2 thereof, with the metal tube being attached thereto, it is achieved sensor and the protection of cable, it is to avoid the damage caused because of violence desilting.
Accompanying drawing explanation
Fig. 1 is the structural representation of throw-in type liquid level sensor protection device.
Detailed description of the invention
The structure and working principle of this device is further illustrated below in conjunction with accompanying drawing.
As it is shown in figure 1, this throw-in type liquid level sensor protection device is made up of sensor protective cover, sensor holders and isolating seal head, detection sealing gland etc..
Sensor holders and isolating seal head are made up of multilamellar O 7, packing ring 6 and fixing head 5, for throw-in type liquid level sensor is fixed on detection sealing gland.Detection sealing gland 10 links together with the fixing head 5 of sensor holders and isolating seal head, and link position multilamellar O 7, packing ring 6 seal.Detection sealing gland 10 has the through hole 9 that gas can be allowed to pass through, and sensor is installed in fixing head 5, can contact with the gas in through hole.
Sensor protective cover 3 is sealed by Flange joint blend rubber pad 8 with detection sealing gland 10, and protection sensor also completely cuts off the corrosive gas in drain pipe, has certain isolation explosion-proof.Sensor protective cover 3 top is provided with external fiber tube hickey 2, it is simple to connects metal tube, is used for protecting sensor cable.Detection sealing gland 10 is a semienclosed container, lower openings communicates with sewage, when sewage level reaches to detect sealing gland, air is closed in sealing gland and is compressed with the rising of liquid level, and the pressure of gas is with relevant relative to the liquid level of sealing gland end opening, under limited sewage level height, the ratio that air is compressed is limited, liquid level in sealing gland rises limited, throw-in type liquid level sensor directly will not contact with having the sewage that burn into contains silt, it is to avoid the dirt of sensor is blocked up.
