Description

Technical Field

[0001] The utility model relates to the technical field of hydrological forecasting equipment, and specifically relates to a hydrological forecasting equipment with an emergency device. Background Art

[0002] According to the previous or current hydrological and meteorological data, making a qualitative or quantitative prediction of the hydrological situation of a certain water body, a certain area or a certain hydrological station within a certain period of time in the future is called hydrological forecasting, which is an important manifestation of hydrology serving the economy and society. Especially making forecasts for disastrous hydrological phenomena is of great significance for flood control, drought resistance, rational utilization of water resources and national defense. At present, hydrological forecasting equipment generally stays close to the water's edge for a long time, and the water's edge is relatively humid. Once the sealing structure of the hydrological forecasting equipment is damaged, moisture can easily enter the interior of the hydrological forecasting equipment. If the moisture fills the interior of the hydrological forecasting equipment for too long, it can easily corrode the internal components of the hydrological forecasting equipment, not only reducing the service life of the hydrological forecasting equipment, but also easily causing a short circuit and damaging the hydrological forecasting equipment.

[0003] In this regard, according to the retrieval report of the novelty search agency, the patent with publication number CN215598403U discloses a hydrological forecasting equipment with an emergency device, including a hydrological forecasting box and an emergency mechanism. An emergency mechanism is arranged inside the hydrological forecasting box. The emergency mechanism includes a gravity box, a moisture-absorbing sponge is arranged inside the gravity box, a rotary shaft is arranged on the gravity box, a support filter screen is arranged inside the gravity box, connecting ears are connected to both sides of the gravity box, fixed bins are arranged on both sides of the rotary shaft, the fixed bins are connected to the hydrological forecasting box, and a rotary spring is connected between the connecting ears and the rotary shaft; through the setting of the corresponding mechanism on the hydrological forecasting equipment, the time for moisture to fill the interior of the hydrological forecasting equipment is reduced, and the possibility of moisture corroding the internal components is reduced. It not only extends the service life of the hydrological forecasting equipment, but also reduces the probability of damage to the hydrological forecasting equipment caused by a short circuit, reduces the impact on the working efficiency of users, and reduces the losses of users.

[0004] The above-mentioned hydrological forecasting equipment with an emergency device disclosed in the technology absorbs moisture in the hydrological forecasting box through a moisture-absorbing sponge. When the moisture-absorbing sponge absorbs water and becomes heavy to a certain extent, it triggers an alarm to remind personnel to replace the moisture-absorbing sponge. However, it still has the following deficiencies: 1. It cannot automatically dehydrate, drain water and dry the moisture-absorbing sponge after absorbing moisture to a certain extent. The method of personnel disassembling and replacing the moisture-absorbing sponge alone is cumbersome, and the degree of automation and convenience in use is not ideal; improvement is needed. In view of this, this application proposes a hydrological forecasting equipment with an emergency device to solve the above problems. Summary of the Utility Model

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 3 shown, a hydrological forecasting device with an emergency device proposed in this embodiment includes a hydrological forecasting device body, and the hydrological forecasting device body includes a hydrological forecasting box 1, and a self-draining emergency dehumidification mechanism is installed in the hydrological forecasting box 1;

[0024] The self - draining emergency dehumidification mechanism includes a support filter plate 2 fixedly installed in the hydrological forecasting box 1. Above the support filter plate 2 is the hydrological equipment area. On the right inner wall of the hydrological forecasting box 1, a PLC controller 3 is fixedly installed below the support filter plate 2. At the right bottom of the hydrological forecasting box 1, an alarm 14 electrically connected to the PLC controller 3 is fixedly installed. Four pressure sensors 4 electrically connected to the PLC controller 3 are fixedly connected in a ring on the bottom inner wall of the hydrological forecasting box 1. At the top of the four pressure sensors 4, there is a same loading box 5 with a conical opening structure at the bottom. A filter plate 6 is fixedly sleeved inside the loading box 5. At the top of the filter plate 6, there is a moisture - absorbing sponge 7 movably sleeved inside the loading box 5. At the top of the support filter plate 2, an extrusion dehydration component matched with the moisture - absorbing sponge 7 is embedded and fixed. On the right side of the hydrological forecasting box 1, a blowing component communicated and fixed with the top of the extrusion dehydration component is installed. Both the extrusion dehydration component and the blowing component are electrically connected to the PLC controller 3. A telescopic one - way drainage component is fixedly connected and communicated between the bottom of the hydrological forecasting box 1 and the bottom of the loading box 5. The moisture - absorbing sponge 7 is used to dehumidify the inside of the hydrological forecasting box 1. As the water in the moisture - absorbing sponge 7 increases and it gradually becomes heavier, it drives the loading box 5 to gradually increase the extrusion force on the pressure sensors 4. The pressure sensors 4 are used to monitor the extrusion force and transmit the pressure value to the PLC controller 3. When the preset cleaning pressure value is reached, the PLC controller 3 controls the alarm 14 to start for alarm reminder. The extrusion dehydration component is used to automatically extrude and dehydrate the moisture - absorbing sponge 7 under the control of the PLC controller 3 when the preset pressure value is reached. The blowing component is used to automatically supply air into the extrusion dehydration component under the control of the PLC controller 3 when the preset pressure value is reached, and form an effect of blowing air downward to dry the moisture - absorbing sponge 7. The telescopic one - way drainage component is used to automatically discharge the drained water and gas downward unidirectionally.

[0025] Specifically, the extrusion dehydration component includes a reciprocating electric push rod 10 embedded and fixed at the top of the support filter plate 2. An embedding hole fixedly connected to the outer side of the reciprocating electric push rod 10 is opened at the top of the support filter plate 2. The extending end of the reciprocating electric push rod 10 extends below the support filter plate 2 and is fixedly connected with a hollow pressing disc 8. The hollow pressing disc 8 is located above the moisture - absorbing sponge 7 and is matched with the moisture - absorbing sponge 7. A plurality of air outlet holes 9 are opened at the bottom of the hollow pressing disc 8. The outer diameter of the hollow pressing disc 8 is smaller than the inner diameter of the loading box 5. The reciprocating electric push rod 10 is electrically connected to the PLC controller 3. The arranged reciprocating electric push rod 10 and the hollow pressing disc 8 cooperate. When the preset pressure value is reached, the PLC controller 3 controls the reciprocating electric push rod 10 to start, driving the hollow pressing disc 8 to move up and down. When the hollow pressing disc 8 moves down, it extrudes and dehydrates the moisture - absorbing sponge 7, making the water flow downward through the filter plate 6.

[0026] Further, the air blowing assembly includes a solenoid valve 13 fixedly installed on the right side of the hydrological forecasting box 1. A blower 12 is fixedly installed on the inner wall of the right side of the hydrological forecasting box 1. The right side of the blower 12 is an air inlet and is fixedly connected to the left end of the solenoid valve 13. The left side of the blower 12 is an air outlet, and a flexible hose 11 is fixedly connected between the air outlet and the upper right side of the hollow pressure plate 8. Both the solenoid valve 13 and the blower 12 are electrically connected to the PLC controller 3. The PLC controller 3 is a programmable controller with timing function. The programmable controller with timing function enables personnel to set the interval time from the start to the stop of the blower 12 and the solenoid valve 13 according to the air drying time requirement. The solenoid valve 13, the blower 12 and the flexible hose 11 are configured such that when the preset pressure value is reached, the PLC controller 3 controls the solenoid valve 13 and the blower 12 to open. The blower 12 sucks external air through the solenoid valve 13, blows the air into the hollow pressure plate 8 through the flexible hose 11, and then blows downward through a plurality of air holes 9 to perform the air drying work on the moisture-absorbing sponge 7.

[0027] Further, the telescopic one-way drainage assembly includes a one-way valve 16 fixedly installed at the bottom of the hydrological forecasting box 1. The top of the one-way valve 16 is fixedly connected to the bottom of the loading box 5 by a telescopic hose 15. An activity perforation for the telescopic hose 15 to pass through is provided on the inner wall of the bottom of the hydrological forecasting box 1. The bottom of the one-way valve 16 is an outlet. The one-way valve 16 and the telescopic hose 15 are configured such that the extruded water or the blown gas is automatically discharged downward through the telescopic hose 15 and the one-way valve 16 to the outside in sequence.

[0028] The usage method of this embodiment is as follows: During use, the moisture-absorbing sponge 7 absorbs the moisture inside the hydrological forecasting box 1, reducing the possibility of moisture corrosion to the internal components. The time for starting the reciprocating electric push rod 10 and the alarm 14 is preset by using the PLC controller 3 according to the cleaning requirement in advance. The time for starting the solenoid valve 13 and the blower 12 and the time interval from the start to the stop are also preset. It is also preset that the alarm 14 is controlled to close synchronously when this interval time is reached. As the moisture-absorbing sponge 7 becomes heavier due to the increase of water, the moisture-absorbing sponge 7 drives the loading box 5 to gradually increase the extrusion force on the pressure sensor 4 through the filter plate 6. The pressure sensor 4 monitors the extrusion force and transmits the pressure value to the PLC controller 3. When the preset cleaning pressure value is reached, the PLC controller 3 controls the alarm 14, the reciprocating electric push rod 10, the blower 12 and the solenoid valve 13 to open, and uses the alarm 14 to give an alarm to remind the personnel that they are in the automatic cleaning state at this time;

[0029] When the reciprocating electric push rod 10 starts, it drives the hollow pressing plate 8 to move up and down. When the hollow pressing plate 8 moves down, it squeezes and dehydrates the moisture-absorbing sponge 7, so that water flows downward through the filter plate 6, and then automatically discharges downward through the telescopic hose 15 and the one-way valve 16 in sequence. When the fan 12 starts, it inhales external air through the solenoid valve 13 and blows it into the hollow pressing plate 8 through the flexible hose 11. The gas then blows downward through multiple air outlets 9 to blow-dry the moisture-absorbing sponge 7. The gas gradually penetrates the moisture-absorbing sponge 7 and is discharged through the telescopic hose 15 and the one-way valve 16 in sequence. When the closing time is reached, the PLC controller 3 controls the fan 12, the solenoid valve 13 and the alarm 14 to automatically close, and waits to perform the cleaning work again when the preset pressure value is reached next time, so as to facilitate the automatic detection of the state of the moisture-absorbing sponge 7 and automatically dehydrate, drain and dry it when it has more water, without the need for personnel to disassemble and replace the moisture-absorbing sponge 7 separately, with simple operation, improving the degree of automation and convenience of use.

[0030] Among them, the PLC controller 3, the solenoid valve 13, the fan 12, the alarm 14 and the pressure sensor 4 in the present utility model are well-known to those skilled in the art, belonging to conventional means or common knowledge. Those skilled in the art can make any selection according to their needs or convenience. In addition, using the PLC controller 3 to receive the pressure value transmitted by the pressure sensor 4 and control the solenoid valve 13, the fan 12, the reciprocating electric push rod 10 and the alarm 14 to turn on when the preset value is reached, and setting the closing time of the solenoid valve 13, the fan 12, the reciprocating electric push rod 10 and the alarm 14 through programming for automatic closing are basic programming numerical control methods well-known to those skilled in the art, all belonging to conventional means or common knowledge, and will not be elaborated here.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
