Detailed Description
The invention is described in detail below with reference to the figures and examples.
It should be noted that the directional terms such as "upper" and "lower" referred to herein are used relative to the drawings, and are only for convenience of description, and should not be construed as limiting the technical scope.
The probe 3 of the prior static pressure type liquid level meter 2 at the bottom of the pool is often blocked, the automatic regulation and control of the liquid level height of the turbid circulating hot water pool 1 through the static pressure type liquid level meter 2 become very difficult, the automation degree is not high in practice, and manual maintenance is often needed. The invention focuses on the reason that the probe 3 of the static pressure type liquid level meter 2 is blocked because the impurity in the turbid circulating hot water pool 1 is more, and the impurity can be deposited at the pool bottom and cover the probe 3 under the action of gravity, and the impurity near the liquid level of the turbid circulating hot water pool 1 is relatively less, so the invention provides a floating pressure guide device of the static pressure type liquid level meter, as shown in figure 1, comprising the static pressure type liquid level meter 2 and a pressure guide device connected with the static pressure type liquid level meter 2, wherein the pressure guide device comprises a floating part 5 and a hose 4, the floating part 5 is kept above the liquid level, the bottom end of the hose 4 is communicated with the bottom end of the static pressure type liquid level meter 2, the top end of the hose 4 is connected with the floating part 5, and the top end of the side surface of the hose 4 is also provided with a water inlet for enabling the liquid level in the hose 4 to be the same as the pool water level.
The basic principle of the invention is that the probe 3 is separated from the environment of the pool bottom by the hose 4, the hose 4 plays a role of isolating the sensor at the bottom end of the static pressure type liquid level meter 2 from the pool bottom, so as to avoid sundries from blocking the static pressure type liquid level meter 2, and simultaneously, the static pressure type liquid level meter 2 can also know the liquid level of the pool water by detecting the water pressure in the hose 4 because the liquid level in the hose 4 is the same as the liquid level of the pool water. Specifically, since the water inlet of the hose 4 is located at the top end away from the bottom of the tank, and impurities in the turbid circulating hot water tank 1 can settle to the bottom of the tank under the action of gravity, the water inlet end of the hose 4 of the present invention is away from the impurities, greatly reducing the risk of the static pressure type liquid level meter 2 being blocked.
In addition, because the water inlet of the hose 4 is small, the possibility that impurities in the turbid circulating hot water tank 1 enter the hose 4 is also small, and the impurities are effectively prevented from being deposited at the probe 3 to cause blockage.
Further, as shown in fig. 1, an auxiliary pipe 6 is arranged on the side of the flexible pipe 4, the auxiliary pipe 6 is connected with the water inlet of the flexible pipe 4, and the opening of the auxiliary pipe 6 faces downwards. According to the invention, the auxiliary pipe 6 is additionally arranged at the hose 4, and the opening of the auxiliary pipe 6 faces downwards, so that the hose 4 can be always filled with pool water. It will be readily appreciated that if a water inlet is provided only at the top end of the side of the hose 4, it is still possible for impurities in the tank to enter the hose 4, and the present invention provides a downwardly opening auxiliary tube 6 at the water inlet, so that impurities, even if entering the auxiliary tube 6, will sink away from the auxiliary tube 6 under their own weight.
It should be noted that the length of the auxiliary tube 6 cannot be too long, and is 10-15 cm. It is easy to understand that if the auxiliary pipe 6 is too long, the bottom end of the auxiliary pipe 6 is still close to the place where the pool bottom has more impurities, and when the pool water flows into the auxiliary pipe 6 and the hose 4, the impurities are easily sucked together.
Further, a filter screen 7 is arranged at the bottom end of the auxiliary pipe 6. The function of said sieve 7 is to limit the entry of impurities into the auxiliary pipe 6 and thus into it. Since the floating impurities in the hose 4 and the auxiliary pipe 6 soaked in the pool water for a long time can enter the hose 4 through the auxiliary pipe 6 and then accumulate at the sensor probe 3, the filter screen 7 arranged at the auxiliary pipe 6 effectively prevents the impurities from entering the auxiliary pipe 6.
Furthermore, the floating pressure guide device of the static pressure type liquid level meter further comprises a blowing device, the blowing device comprises a gas supply device 9 and a blowing pipe 10, the top end of the blowing pipe 10 is connected with the gas supply device 9, the lower end of the blowing pipe 10 is connected with the auxiliary pipe 6, and the bottom end of the blowing pipe 10 faces the filter screen 7. Specifically, when the filter screen 7 is completely covered by impurities, the air supply device 9 is started, and the air blowing pipe 10 blows high-pressure air to the filter screen 7, so that the impurities at the filter screen 7 are cleaned.
It can be easily understood that, since the impurities are attached to the outer surface of the strainer 7, when the high-pressure air is blown out from the air blowing pipe 10 located on the inner surface side of the strainer 7, the impurities attached to the outer surface of the strainer 7 can be completely blown away, and the impurities are prevented from blocking the pool water from flowing into the auxiliary pipe 6 and the hose 4.
Furthermore, the top end of the hose 4 is provided with a detection sensor 8, the detection sensor 8 is in a state of just contacting with the liquid level in the hose 4, and whether the liquid level height in the hose 4 is in a normal state is detected.
The detection sensor 8 according to the present invention is a conventional sensor for detecting the presence of liquid. The present invention is provided with a detection sensor 8 at the tip of the hose 4 in order to detect whether the liquid surface in the hose 4 is flush with the liquid surface of the turbid circulating hot water tank 1 when the float 5 is functioning normally. It is easily understood that the detection sensor 8 is disposed at a position where the liquid level in the hose 4 is slightly lower when the floating portion 5 drives the hose 4 to float in the turbid circulating hot water tank 1, that is, the detection sensor 8 needs to be in contact with the liquid level, and when the liquid level cannot be detected by the detection sensor 8, it is indicated that the liquid level in the hose 4 is lower than the liquid level of the turbid circulating hot water tank 1.
In the invention, the bottom end of the hose 4 is provided with an installation chamber 11, and the probe 3 of the static pressure type liquid level meter 2 is arranged in the installation chamber 11; the floating part 5 is a float.
A using method of a floating pressure guide device of a static pressure type liquid level meter is used for the floating pressure guide device of the static pressure type liquid level meter, and comprises the following specific steps:
arrange probe 3 of static pressure type level gauge 2 in installation chamber 11 of 4 bottoms of hose, all put into turbid ring hot-water pond 1 with installation chamber 11 and hose 4, installation chamber 11 drives probe 3 and sinks into 1 bottom of the pool of turbid ring hot-water pond, simultaneously hose 4 is whole to be in the pond aquatic, 4 tops of hose are driven by the portion of floating 5 and are floated on turbid ring hot-water pond 1 liquid level, the pond water flows into in hose 4 through auxiliary tube 6, be full of hose 4, the liquid level in hose 4 flushes with turbid ring hot-water pond 1's liquid level this moment, thereby static pressure type level gauge 2 obtains turbid ring hot-water pond 1's liquid level height through the liquid level in measuring hose 4.
Further, the air supply device 9 is started at regular or irregular time, and high-pressure air is blown out to the filter screen 7 of the auxiliary pipe 6 through the air blowing pipe 10 to blow out deposited impurities out of the filter screen 7.
Furthermore, when the liquid level in the hose 4 can not be detected by the detection sensor 8, the air supply device 930-60s is automatically started, and the compressed air is blown out to the filter screen 7 of the auxiliary pipe 6 through the air blowing pipe 10 to blow out the deposited impurities out of the filter screen 7;
if the detection sensor 8 again detects liquid in the hose 4, the air supply means 9 is stopped;
