Description

Technical Field

[0001] This utility model relates to the field of roof drainage technology, specifically to a technology for an electric switching valve for roof siphon drainage failure. Background Technology

[0002] In modern buildings, rainwater tends to accumulate on roofs due to rainfall and other factors. When rainwater accumulates on the roof, it can cause structural deformation, subsidence, or even collapse. This risk is even higher for older buildings or buildings with limited roof structural strength. In addition, water can seep into the roof building materials, such as concrete and bricks, corroding the materials, reducing their durability, and accelerating roof aging and damage. Therefore, the efficiency and reliability of the roof drainage system are crucial.

[0003] Roof siphon drainage systems, with their unique siphon principle, can generate a siphon effect by utilizing the height of the building roof and the potential energy of rainwater. By changing the pipe diameter to create negative pressure, rainwater on the roof can be discharged quickly at a high flow rate. They have the advantages of saving pipe materials and building space and are widely used in large public buildings such as shopping malls, exhibition halls, stadiums, and large factories.

[0004] While existing technologies can achieve normal drainage using siphon drainage, roof siphon drainage systems also face many problems in actual operation. It is not convenient to strictly control the water depth in front of the hopper. If it is too shallow, the siphon drainage pipe will not be able to function properly. If it is too deep, it will increase the load on the building roof, bringing safety risks and increased costs. At the same time, the manual switching method is not only inefficient, but may also fail to respond in time in emergency situations, resulting in water accumulation on the roof, damage to the building structure, and even safety accidents. Summary of the Invention

[0005] The purpose of this invention is to provide an electric switching valve technology for roof siphon drainage failures, which aims to effectively solve the problems in the existing technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An electrically operated switching valve for roof siphon drainage failure includes a water collection hopper and an electric actuator. The inner surface of the water collection hopper has a collection groove. A drain pipe is provided on one side of the water collection hopper. A connecting pipe is bolted to the other end of the drain pipe away from the collection groove. An electric valve body is provided on the outer surface of the connecting pipe. A valve stem and a valve cover are provided on the outer surface of the electric valve body. A power cord and a first connecting line are provided on the outer surface of the electric actuator. A water level monitoring component is provided on the inner surface of the water collection hopper.

[0008] Preferably, the water level monitoring component includes a liquid level sensor, and a sensor housing and a probe are fixedly installed on the outer surface of the liquid level sensor. The liquid level sensor, sensor housing and probe are an integral structure.

[0009] The above technical solution involves installing the water level monitoring component on the inner surface of the water collection hopper. The probe of the liquid level sensor directly contacts the water in the collection hopper to monitor the water level in real time. The integrated structure makes the installation and maintenance of the liquid level sensor more convenient, reduces the connection links between components, and lowers the probability of failure. The sensor housing can effectively protect the internal circuit of the liquid level sensor. The probe directly contacts the water body and can accurately and quickly sense changes in water level, ensuring the timeliness and accuracy of water level monitoring.

[0010] Preferably, the outer surface of the liquid level sensor is provided with a limiting block, a mounting cover and a connecting block, and two identical limiting blocks, mounting covers and connecting blocks are provided, and the two limiting blocks, mounting covers and connecting blocks together form an "Ω" shaped structure.

[0011] Through the above technical solution, the "Ω" shaped structure design can firmly fix the liquid level sensor in the water collection hopper, the limiting block can prevent the liquid level sensor from shifting, and the mounting cover provides further protection for the liquid level sensor, preventing it from being damaged by collisions or other external forces, thus ensuring the stability of the liquid level sensor's operation.

[0012] Preferably, a first positioning bolt is provided through the outer surface of the limiting block, the first positioning bolt passes through the limiting block and extends to the inner surface of the water collecting hopper, and a second positioning bolt is provided through the outer surface of the connecting block.

[0013] Through the above technical solutions, the first and second positioning bolts further enhance the stability of the liquid level sensor installation, preventing it from shaking or falling off inside the water collection hopper. This ensures that the liquid level sensor can continuously and accurately monitor the water level, ensuring the reliability of the entire drainage system. Furthermore, the probe can be extended into the water collection hopper and other components can be installed on the outside of the water collection hopper according to actual conditions, improving the overall device versatility.

[0014] Preferably, the liquid level sensor has a connection end on its outer surface, and a second connection line is provided on the outer surface of the connection end. The second connection line is located on the outer surface of the water collection hopper and is connected to the first connection line.

[0015] Through the above technical solution, after the liquid level sensor is installed and fixed, the second connecting wire is connected to the liquid level sensor through the connecting end. Then, the second connecting wire is led out of the water collection hopper and connected to the first connecting wire of the electric actuator to complete the circuit connection. This allows the liquid level sensor to smoothly transmit the monitored water level signal to the electric actuator, realizing the effective transmission of the water level signal. As a result, the electric actuator controls the working state of the electric valve body according to the water level, ensuring the automated operation of the entire drainage system.

[0016] Preferably, the collection tank, drain pipe, and connecting pipe are interconnected, and the water level monitoring component is a waterproof monitor.

[0017] Through the above technical solutions, the interconnection of the collection tank, drainage pipe and connecting pipe ensures that rainwater can be discharged smoothly, improving drainage efficiency. The waterproof design of the water level monitoring component enables it to work stably in the humid water collection tank environment, avoiding damage caused by water ingress and ensuring the continuity and accuracy of water level monitoring.

[0018] Preferably, an electric actuator is fixedly mounted on the outer surface of the electric valve body, and the electric actuator is adapted to the electric valve body and valve stem.

[0019] Through the above technical solution, when the liquid level sensor detects that the water level has reached the preset danger level, it transmits the signal to the electric actuator through the connecting line. After receiving the signal, the electric actuator drives the valve stem to control the electric valve body to open or close, switching the drainage path. This allows the electric actuator to accurately control the working state of the electric valve body, achieving rapid and accurate switching of the drainage path. When the roof siphon drainage main system fails, it can promptly guide rainwater into a specially designed overflow system, preventing water accumulation on the roof, improving the drainage system's ability to cope with emergencies, and ensuring building safety.

[0020] Compared with the prior art, the electric switching valve for roof siphon drainage failure provided by this utility model has the following advantages:

[0021] 1. The electric switching valve for roof siphon drainage failure features an integrated structure of liquid level sensor, sensor housing, and probe, which reduces the probability of failure. The probe can quickly and accurately sense changes in water level. The "Ω" shaped structure formed by the limit block, mounting cover, and connecting block, along with the first and second positioning bolts, ensures that the liquid level sensor is installed securely and continuously and accurately monitors the water level, preventing the water level from being too high or too low.

[0022] 2. This roof siphon drainage fault electric switching valve, through signal transmission between the liquid level sensor and the electric actuator, realizes automatic control of the working state of the electric valve body according to the water level, without manual intervention, improving the automation level of the drainage system. It can respond promptly to faults in the main roof siphon drainage system. When the main roof siphon drainage system fails, the electric switching valve can quickly and accurately switch the drainage path, directing rainwater into the overflow system to avoid water accumulation on the roof, effectively improving the drainage system's ability to cope with emergencies and ensuring building safety.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1-3 As shown in the figure, this example provides an electric switching valve for roof siphon drainage failure. Based on the figure, the electric switching valve for roof siphon drainage failure specifically includes a water collection hopper 1 and an electric actuator 8. The inner surface of the water collection hopper 1 is provided with a collection groove 2. A drain pipe 3 is provided on one side of the water collection hopper 1. The other end of the drain pipe 3 away from the collection groove 2 is connected to a connecting pipe 4 by bolts. An electric valve body 5 is provided on the outer surface of the connecting pipe 4. A valve stem 6 and a valve cover 7 are provided on the outer surface of the electric valve body 5. A power line 9 and a first connecting line 10 are provided on the outer surface of the electric actuator 8. A water level monitoring component 11 is provided on the inner surface of the water collection hopper 1.

[0032] For further explanation, see Figures 4 to 6 In this example, the water level monitoring component 11 specifically includes a liquid level sensor 1101, on which a sensor housing 1102 and a probe 1103 are fixedly mounted on the outer surface. The liquid level sensor 1101, the sensor housing 1102, and the probe 1103 are an integral structure.

[0033] With this configuration, the water level monitoring component 11 is installed on the inner surface of the water collection hopper 1, and the probe 1103 of the liquid level sensor 1101 directly contacts the water in the water collection hopper 1 to monitor the water level in real time. The integrated structure makes the installation and maintenance of the liquid level sensor 1101 more convenient, reduces the connection links between components, and lowers the probability of failure. The sensor housing 1102 can effectively protect the internal circuit of the liquid level sensor 1101. The probe 1103 directly contacts the water body and can accurately and quickly sense changes in water level, ensuring the timeliness and accuracy of water level monitoring.

[0034] For further explanation, see Figures 4 to 6 In this example, a limiting block 1104, a mounting cover 1106, and a connecting block 1107 are provided on the outer surface of the liquid level sensor 1101. Two identical limiting blocks 1104, mounting covers 1106, and connecting blocks 1107 are provided, and the two limiting blocks 1104, mounting covers 1106, and connecting blocks 1107 together form an “Ω” shaped structure.

[0035] Thus, the “Ω” shaped structure design can firmly fix the liquid level sensor 1101 in the water collection hopper 1, the limiting block 1104 can prevent the liquid level sensor 1101 from being displaced, and the mounting cover 1106 provides further protection for the liquid level sensor 1101, preventing it from being damaged by collisions or other external forces, and ensuring the stability of the operation of the liquid level sensor 1101.

[0036] For further explanation, see Figures 4 to 6In this example, a first positioning bolt 1105 is provided through the outer surface of the limiting block 1104. The first positioning bolt 1105 passes through the limiting block 1104 and extends to the inner surface of the water collection hopper 1. A second positioning bolt 1108 is provided through the outer surface of the connecting block 1107.

[0037] This configuration, through the first positioning bolt 1105 and the second positioning bolt 1108, further enhances the stability of the liquid level sensor 1101 installation, preventing it from shaking or falling off inside the water collection hopper 1. This ensures that the liquid level sensor 1101 can continuously and accurately monitor the water level, ensuring the reliability of the entire drainage system. Furthermore, it allows the probe 1103 to be extended into the water collection hopper 1 and other components to be installed on the outside of the water collection hopper 1, thereby increasing the versatility of the overall device.

[0038] For further explanation, see Figures 4 to 5 In this example, a connection terminal 1109 is provided on the outer surface of the liquid level sensor 1101, and a second connecting line 12 is provided on the outer surface of the connection terminal 1109. The second connecting line 12 is located on the outer surface of the water collection hopper 1 and is connected to the first connecting line 10. With this configuration, after the liquid level sensor 1101 is installed and fixed, the second connecting line 12 is connected to the liquid level sensor 1101 through the connection terminal 1109. Then, the second connecting line 12 is led out of the water collection hopper 1 and connected to the first connecting line 10 of the electric actuator 8, completing the circuit connection. This allows the liquid level sensor 1101 to smoothly transmit the monitored water level signal to the electric actuator 8, realizing the effective transmission of the water level signal. As a result, the electric actuator 8 controls the working state of the electric valve body 5 according to the water level, ensuring the automated operation of the entire drainage system.

[0039] For further explanation, see Figures 1 to 3 In this example, the collection tank 2, drain pipe 3, and connecting pipe 4 are interconnected, and the water level monitoring component 11 is a waterproof monitor. This configuration ensures that rainwater can be smoothly discharged, improving drainage efficiency. The waterproof design of the water level monitoring component 11 allows it to work stably in the humid environment of the water collection tank 1, avoiding damage caused by water ingress and ensuring the continuity and accuracy of water level monitoring.

[0040] For further explanation, see Figure 3 In this example, an electric actuator 8 is fixedly installed on the outer surface of the electric valve body 5. The electric actuator 8 is compatible with the electric valve body 5 and the valve stem 6.

[0041] With this configuration, when the liquid level sensor 1101 detects that the water level has reached the preset danger level, it transmits the signal to the electric actuator 8 through the connecting line. After receiving the signal, the electric actuator 8 drives the valve stem 6 to control the electric valve body 5 to open or close, switching the drainage path. This allows the electric actuator 8 to accurately control the working state of the electric valve body 5, achieving rapid and accurate switching of the drainage path. When the roof siphon drainage main system fails, it can promptly guide rainwater into the specially designed overflow system, preventing water accumulation on the roof, improving the drainage system's ability to cope with emergencies, and ensuring building safety.

[0042] To further illustrate the operation of the electric switching valve for roof siphon drainage failure presented in this example, the following example demonstrates its operation.

[0043] Combination Figures 1 to 6 When the electric switching valve for the siphon drainage failure of this roof is in use, the liquid level sensor 1101 in the water level monitoring component 11 is installed on the inner surface of the water collection hopper 1, and its probe 1103 directly contacts the water in the collection tank 2 of the water collection hopper 1 to sense the water level change in real time. The liquid level sensor 1101 converts the water level information into an electrical signal, which is transmitted to the outside of the water collection hopper 1 through the connection terminal 1109 and the second connection line 12, and is connected to the first connection line 10 of the electric actuator 8 to transmit the water level signal to the electric actuator 8.

[0044] Under normal circumstances, rainwater flows into the collection tank 2 of the water collection hopper 1 and is drained through the interconnected drain pipe 3 and connecting pipe 4. When the liquid level sensor 1101 detects that the water level has reached the preset danger level and the roof siphon drainage main system may be malfunctioning, it transmits a signal to the electric actuator 8. After receiving the signal, the electric actuator 8 drives the valve stem 6 connected to the electric valve body 5 to control the electric valve body 5 to open or close, thereby switching the drainage path and directing the rainwater into the specially set overflow system.

[0045] The electric actuator 8 obtains power through the power line 9 on its outer surface to power its operation. The control signal is transmitted through the first connection line 10. Based on the water level signal transmitted by the liquid level sensor 1101, the electric actuator 8 precisely controls the working state of the electric valve body 5 to realize the automated operation of the drainage system.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
