Description

Technical Field

[0001] The invention relates to the technical field of water leakage monitoring devices, in particular to an online monitoring and processing device for water leakage of air-conditioning equipment. Background Art

[0002] In order to control the temperature of each production area, various types of air-conditioning equipment are arranged between the electrical equipment in the production plant. Once the air-conditioning equipment itself leaks or the condensed water is not drained smoothly, it will affect the safe and stable operation of nearby electrical equipment.

[0003] There are complete sets of water leakage detection cables on the market. The working principle of water leakage detection cables is based on the conductivity of the conductor wire inside. When water penetrates the sensing rope and contacts the conductor wire, the conductivity of the water will cause the voltage in the circuit to change, thus triggering an alarm. This cable is usually used in conjunction with a water leakage controller. Once a liquid leak is detected, a signal will be transmitted to the controller and an alarm will be triggered.

[0004] The price of water leakage detection cables is relatively high. Various types of air-conditioning equipment are widely distributed in large production plants, and the cost of laying water leakage detection cables is relatively high. Summary of the invention

[0005] The technical problem to be solved by the present invention is that it is too costly to arrange a large number of water leakage detection cables around air conditioning equipment.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: an online monitoring and processing device for water leakage of air-conditioning equipment, comprising a water receiving tray with an opening on the top, a supporting grille for supporting the air-conditioning equipment arranged in the water receiving tray, a drainage groove is arranged in the middle of the bottom wall of the water receiving tray, one end of the drainage groove is connected to a connecting pipe, both sides of the drainage groove are evenly connected with guide grooves and connected with each grid in the supporting grille through the guide groove, and the movable end of the connecting pipe is provided with a monitoring system for controlling the opening and closing of the air-conditioning equipment and the water leakage alarm.

[0007] Preferably, the movable end of the connecting pipe is connected to a water tank, an overflow pipe is provided on the top of the water tank, a float valve and a drain pipe are provided on the bottom of the water tank, and the monitoring system of the air-conditioning equipment is connected to the passive normally open node of the float valve.

[0008] Preferably, the overflow pipe is lower than the top surface of the supporting grid.

[0009] Preferably, a dustproof net is provided on the top of the cavity of the supporting grille, and the dustproof net is overlapped on the supporting grille through a rectangular frame.

[0010] Preferably, the bottom of the guide groove is wedge-shaped, and the relative outer walls of the water receiving tray are respectively connected to the air supply duct and the air outlet duct, the air supply duct and the air outlet duct are respectively arranged corresponding to the guide groove, and the part of the supporting grille located directly above the guide groove is provided with a ventilation hole for air flow to flow along the guide groove.

[0011] Preferably, the air supply duct and the air outlet duct are both provided with an exhaust pipe and a branch pipe arranged in parallel on the exhaust pipe, the bottom end of the branch pipe is obliquely connected to the side wall of the water receiving tray, the exhaust pipe is located above the water receiving tray, and a guide slope is provided on one end of the guide groove close to the branch pipe.

[0012] Preferably, a support platform is arranged between adjacent guide grooves, and the bottom surface of the support grid is in contact with the top surface of the support platform.

[0013] Preferably, the input end of the air supply duct is connected to the outdoor air outlet duct of the air conditioning equipment, and the air supply duct is connected to an induced draft fan and is connected to the outdoors through the induced draft fan.

[0014] A method for using an online monitoring and processing device for water leakage of air conditioning equipment comprises the following steps: Step 1: water collection. When the air conditioning equipment leaks, the leaked water enters the water receiving tray through the support grille. The water receiving tray collects the water through the guide groove at the bottom and guides it into the drainage groove. The water in the drainage groove enters the monitoring system through the connecting pipe. Step 2: Alarm. The float valve inside the monitoring system rises after water enters, so that the passive normally open node inside the float valve is triggered, and then the water leakage alarm is turned on to alarm the water leakage, and the overflow pipe inside the monitoring system discharges the water; Step three, drying. After the water leakage alarm is triggered, the air supply duct sends the hot air from the outdoor unit into the guide groove through the branch pipe. The hot air dries the residual water on the inner wall of the guide groove and enters the air outlet duct for discharge.

[0015] 1. The present invention provides an online monitoring and processing device for water leakage of air-conditioning equipment, which uses a water receiving tray, a connecting pipe, a water storage tank and an overflow pipe to discharge water leakage of the air-conditioning equipment body or overflow and leakage caused by poor drainage of condensed water in real time, thereby improving the safety of air-conditioning equipment operation.

[0016] 2. The float valve installed in the connecting pipe and the water tank can quickly convert water leakage into a passive switch node signal, and can promptly transmit the signal to the control system of the air-conditioning equipment, so that the staff can promptly perform maintenance on the leaking air-conditioning equipment; the use of a float valve for water leakage detection, in conjunction with a water collection tray, reduces the cost of water leakage detection for air-conditioning equipment.

[0017] 3. The dust-proof net on the top of the supporting grille can reduce the dust from entering the guide groove and drainage groove, ensure the smooth flow of water, and reduce the impact on the water tank and its internal float valve.

[0018] 4. The air supply duct uses the low-humidity gas from the outdoor unit of the air-conditioning equipment to quickly dehumidify the guide groove, and discharges the gas through the air outlet duct to ensure that the electrical equipment room is in a dry environment.

DETAILED DESCRIPTION

[0023] like Figure 1-3 As shown, the present invention provides an online monitoring and processing device for water leakage of air-conditioning equipment, including a water receiving tray 1 with an opening on the top, a supporting grille 2 for supporting the air-conditioning equipment 3 is arranged in the water receiving tray 1, a drainage groove 10 is arranged in the middle of the bottom wall of the water receiving tray 1, one end of the drainage groove 10 is connected to a connecting pipe 4, both sides of the drainage groove 10 are evenly connected with guide grooves 9 and are connected with each grid in the supporting grille 2 through the guide grooves 9, and a monitoring system for controlling the opening and closing of the air-conditioning equipment 3 and a water leakage alarm is arranged at the movable end of the connecting pipe 4.

[0024] The water receiving pan 1 is used as the base, and the support grille 2 is installed in the water receiving pan 1 to support the air conditioning equipment 3. When the air conditioning equipment 3 leaks, the water can be supported to enter the water receiving pan 1 through the support grille 2, and collect in the guide groove 9, and then flow to the drainage groove 10 through the guide groove 9, and finally enter the connecting pipe 4, and trigger the water leakage detector, which sends a signal to the control system of the air conditioning equipment 3, shuts down the air conditioning equipment 3, and triggers the water leakage alarm. At this time, the central air conditioning monitoring system receives the single-machine water leakage signal transmitted by the water leakage detector, and the staff promptly repairs the leaking air conditioning equipment 3. During the maintenance process, the staff stands on the support grille 2, and because the accumulated water is located under the support grille 2, the safety of the staff's maintenance construction is guaranteed.

[0025] like Figure 1 As shown. The movable end of the connecting pipe 4 is connected to a water storage tank 5, an overflow pipe 7 is provided on the top of the water storage tank 5, a float valve 6 and a drain pipe are provided at the bottom of the water storage tank 5, and the monitoring system of the air conditioning equipment 3 is connected to the passive normally open node of the float valve 6. When the air conditioning equipment 3 leaks, the water flows into the water storage tank 5 through the guide groove 9 and the drainage groove 10, causing the water level in the water storage tank 5 to rise, causing the float in the float valve 6 to rise, and triggering the passive normally open node of the monitoring system, so that the water leakage signal is issued and the air conditioning equipment 3 is shut down; the drain pipe at the bottom of the air conditioning equipment 3 is used to drain water.

[0026] like Figure 2 As shown. The overflow pipe 7 is lower than the top surface of the support grille 2. When the water leakage of the air-conditioning equipment 3 per unit time is greater than the drainage of the drainage pipe per unit time, the water in the water storage tank 5 is discharged through the overflow pipe 7, and the water level inside the water receiving tray 1 is maintained lower than the top of the water receiving tray 1 to prevent the water receiving tray 1 from overflowing.

[0027] like Figure 1 and Figure 2 As shown. The top of the cavity of the support grille 2 is provided with a dustproof net 8, which is overlapped on the support grille 2 through a rectangular frame. The dustproof net 8 reduces dust and prevents debris from entering the water receiving tray 1, ensuring the smooth flow of the guide groove 9 and the drainage groove 10 inside the water receiving tray 1.

[0028] like Figure 2 As shown. The bottom of the guide groove 9 is wedge-shaped, and the opposite outer side walls of the water receiving tray 1 are respectively connected with an air supply duct and an air outlet duct, which are respectively arranged corresponding to the guide groove 9. The portion of the support grille 2 located directly above the guide groove 9 is provided with a ventilating opening for air flow to flow along the guide groove 10. After the leaking air conditioning equipment 3 is repaired, dry gas is input through the air supply duct to dehumidify the inside of the guide groove 9 to prevent the residual water in the guide groove 9 from evaporating and increasing the humidity between the electrical equipment. The dehumidified gas is discharged through the air outlet duct.

[0029] like Figure 3 As shown. The air supply duct and the air outlet duct are both provided with an exhaust duct 11 and a branch pipe 12 arranged in parallel on the exhaust duct 11. The bottom end of the branch pipe 12 is obliquely connected to the side wall of the water receiving tray 1. The exhaust duct 11 is located above the water receiving tray 1. The end of the guide groove 9 close to the branch pipe 12 is provided with a guide slope. The guide slope guides the input airflow so that the airflow can flow along the guide groove 9, and then the interior of the guide groove 9 can be dehumidified smoothly; the height arrangement of the exhaust duct 11 can prevent water leakage from entering the air conditioning equipment 3.

[0030] like Figure 2 and Figure 3As shown, in order to ensure the stable installation of the support grille 2, a stable support is provided for the air conditioning device 3. A support platform 13 is arranged between adjacent guide grooves 9, and the bottom surface of the support grille 2 is in contact with the top surface of the support platform 13.

[0031] As a preferred embodiment of the present invention, the input end of the air supply duct is connected to the external air outlet duct of the air conditioning device 3, and the air supply duct is connected to an induced draft fan, and is connected to the outdoors through the induced draft fan. The external air exhaust duct of the central air conditioner is used to transport part of the high-temperature low-humidity gas to the guide groove 9, and the inside of the guide groove 9 is quickly dehumidified.

[0032] A method for using an online monitoring and processing device for water leakage of air conditioning equipment comprises the following steps: Step 1: water collection. When the air conditioning equipment 3 leaks, the leaked water enters the water receiving pan 1 through the support grille 2. The water receiving pan 1 collects the water through the guide groove 9 at the bottom and guides it to the drainage groove 10. The water in the drainage groove 10 enters the monitoring system through the connecting pipe 4. Step 2: alarm. The float valve 6 inside the monitoring system rises after water enters, so that the passive normally open node inside the float valve 6 is triggered, and then the water leakage alarm is turned on to alarm the water leakage, and the overflow pipe 7 inside the monitoring system discharges the water; Step three, drying. After the water leakage alarm is triggered, the air supply duct sends the hot air from the external unit into the guide groove 9 through the branch pipe 12. The hot air dries the water remaining on the inner wall of the guide groove 9 and enters the air outlet duct for discharge.
