As shown in FIG. 1, the embodiment of the utility model provides a marine power plant boiler water level measurement sensor, include: the electric contact probe 7 is sleeved with the shielding sleeve 6, and the shielding sleeve 6 is used for reducing the contact between sediment in the water body and the electric contact probe 7.
Specifically, the embodiment of the utility model provides a boiler water level measurement sensor is applied to marine power device, and boiler water level measurement sensor is used for measuring the water level in the measuring cylinder that links to each other with the boiler under the general condition, and its working medium is high temperature high pressure boiler water, and the water in the measuring cylinder promptly is high temperature high pressure boiler water. As sediment is inevitably generated in the water body in the measuring cylinder, the sediment can cover the electric contact probe 7, and the boiler water level detected by the electric contact probe 7 generates errors. Therefore, in the embodiment of the utility model, increased in boiler water level measuring sensor and hidden sleeve 6, will hide the sleeve cover and establish in the electric contact probe 7 outside.
When the boiler water level measuring sensor is used for measuring the water level in the measuring cylinder, the boiler water level measuring sensor is vertically arranged on the sensor mounting seat, the sensor mounting seat is vertically arranged on the measuring cylinder and communicated with the measuring cylinder, and an electric contact probe of the boiler water level measuring sensor is positioned in the sensor mounting seat. The measuring cylinder is arranged vertically, i.e. the axis of the electric contact probe 7 is ensured to be vertical. In the process of the water body in the measuring cylinder churning, sediment in the water body can be deposited on the upper surface of the object under the action of gravity, and the sediment which can be attached to the vertical surface of the object is few. Deposit just can attach in the water of the regional perpendicular top of electric contact probe 7 side of electric contact, and deposit less entering in the water at measuring section of thick bamboo middle part hides the area that the sleeve 6 encloses, has reduced the water volume of the regional perpendicular top in the vicinity of electric contact probe 7, consequently only hides the deposit in the water in the area that the sleeve 6 encloses and can attach in electric contact probe 7 surface, and should hide the area that the sleeve 6 encloses and water is few, consequently can attach in the deposit on electric contact probe 7 surface also very little, consequently the utility model discloses a hide the sleeve 6 and reduce the possibility that the deposit in a large amount of water is attached to electric contact probe 7 surface. When the water level in the measuring cylinder slowly rises, as shown in fig. 2, the water level measuring sensor of the boiler is partially immersed in the water body, the area 1 is filled with water, the rising height of the water level in the measuring cylinder is limited due to the existence of air in the covering sleeve 6, the water body in the measuring cylinder cannot completely compress the air in the covering sleeve 6, only a small amount of air can be compressed, and therefore, only a small amount of water enters the area surrounded by the covering sleeve 6. In fig. 2, water cannot enter the area 2, and sediment in the water cannot be attached to the surface of the electric contact probe 7.
The embodiment of the utility model provides a marine power device boiler water level measurement sensor, include: the covering sleeve is sleeved outside the electric contact probe, so that the contact between sediment in a water body and the electric contact probe can be reduced, the electric contact probe is prevented from being connected with the cylinder wall of the measuring cylinder to form a loop, the electric contact probe at the measuring point is prevented from being short-circuited, the effectiveness of the boiler water level measuring sensor is ensured, and the boiler water level at the measuring point can be accurately measured.

The side wall of the electrode insulating tube 3 is vertical to the horizontal plane, so that the sediment in the water body can be effectively prevented from being deposited on the surface of the electric contact probe, and the electrode cap 1 is prevented from being communicated with the wall of the measuring cylinder. The shielding sleeve 6 can be welded on the outer side of the electrode holder 4, and the shielding sleeve 6 is connected with the electrode holder 4 in a sealing manner. The material of the blanking sleeve 6 may be the same as the material of the electrode holder 4.
The covering sleeve 6 covers the whole electrode insulating tube 3, and because the boiler water level measuring sensor is vertically arranged, only the sediment in the water body in the area enclosed by the covering sleeve 6 can be attached to the tube wall of the electrode insulating tube 3, and the water body in the area enclosed by the covering sleeve 6 is less, so that the sediment attached to the tube wall of the electrode insulating tube 3 is less. When the water level in the measuring cylinder slowly rises, as shown in fig. 3, the front end part of the water level probe is immersed in water, the area 1 is filled with water, and because air exists in the covering sleeve 6, the rising height of the water level in the measuring cylinder is limited, the water in the measuring cylinder cannot completely compress the air in the covering sleeve 6, and only a small part of air can be compressed, so that only a small amount of water enters the covering sleeve 6, the compressed water level most probably does not submerge the joint of the electrode cap 1 and the electrode insulating tube 3, as shown in fig. 2, the water cannot enter the area 2, and the sediment in the water cannot be attached to the side wall of the electrode insulating tube 3. Therefore, the side wall of the vertical electrode insulating tube 3 is not adhered with more deposits, so that the short circuit connection between the electrode cap 1 and the electrode seat 4 due to the covering of the conductive deposits is prevented, and the risk of the short circuit between the electrode cap 1 and the side wall of the measuring cylinder due to the deposition of the conductive deposits is effectively prevented.
Because the water body which can enter the interior of the covering sleeve 6 is very little, under the condition that the water level in the measuring cylinder does not fluctuate violently, the welding position of the electrode cap and the electrode insulating tube cannot be submerged, the possibility that the water body contacts the welding position of the electrode cap and the electrode insulating tube and the welding position of the electrode insulating tube and the electrode base is reduced, and the electrochemical corrosion possibility is further reduced. Even the welding part is damaged, because the existence of the inside air of the sleeve that hides, inside water in the measuring cylinder can not get into boiler water level measuring sensor, like region 2 in fig. 2, reduce the possibility that boiler water level measuring sensor is corroded, guarantee that measuring cylinder internal pressure border is not lost, improve boiler water level measuring sensor's use reliability.
