Description

Technical Field

[0001] The invention relates to the technical field of measurement and detection, and in particular to a residential elevator shaft water accumulation measurement and alarm device. Background Art

[0002] The residential elevator shaft water accumulation measurement and alarm device is a device used to monitor the water accumulation in the elevator shaft and give an alarm in time to prevent elevator failure or safety accidents caused by water accumulation. The existing measurement and alarm devices are basically electronic intelligent devices, including the following components: Sensor: Water level sensor: used to detect the water level in the elevator shaft. Common ones include electrode type, ultrasonic type and float type sensors. Temperature sensor: monitors the ambient temperature to prevent false alarms caused by temperature changes.

[0003] Data acquisition and processing unit: Microprocessor: responsible for collecting sensor data and processing it.

[0004] Storage module: stores historical data for subsequent analysis and troubleshooting.

[0005] Alarm system: Sound and light alarm: When the water accumulation exceeds the preset threshold, it will send out sound and light signal alarm. Remote alarm: The alarm information will be sent to the manager's mobile phone or monitoring center through wireless communication module (such as GSM, LoRa, etc.).

[0006] Power supply system: Backup power supply: When the main power supply fails, the backup power supply ensures that the device continues to work.

[0007] Power management module: optimizes power usage and extends battery life.

[0008] Although the measurement alarm device composed of the above-mentioned components can effectively monitor the water level of the elevator shaft, it has the following problems during use: because it is placed in the elevator shaft, the air is humid, and for electronic products, the damage failure rate is extremely high due to long-term contact with humid air, that is, the alarm device itself needs to be regularly inspected and repaired, which is not conducive to long-term and low-cost operation; in addition, it needs to be driven by electricity. For the same reason, the accumulated water and humid air in the elevator shaft are very prone to leakage danger;

[0009] Therefore, in view of the above-mentioned problems, the present technical solution proposes a residential elevator shaft water accumulation measurement and alarm device. Summary of the invention

[0010] The object of the present invention is to provide a residential elevator shaft water accumulation measurement and alarm device to solve the problems raised in the above-mentioned background technology.

[0011] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a residential elevator shaft water accumulation measurement and alarm device, comprising a measurement alarm box; one side of the measurement alarm box is fixedly mounted on the elevator shaft wall through a mounting plate, the measurement alarm box is configured as a rectangular sealed structure, a side surface of the measurement alarm box facing the middle of the elevator shaft is engraved with a water level measurement line for measuring the accumulated water level, an alarm water level inlet is provided at the upper portion of the side wall of the measurement alarm box, and a one-way discharge valve port is provided at the lower portion;

[0012] The knocking alarm mechanism is installed on the upper side of the measuring alarm box. The top of the knocking alarm mechanism is connected to the alarm water level inlet. A water collecting tank installed at the bottom of the measuring alarm box is arranged at intervals at the bottom. One side of the water collecting tank is connected to the one-way discharge valve port. An automatic drainage control system is arranged on the side of the water collecting tank away from the one-way discharge valve port. The knocking alarm mechanism includes a lifting and swinging assembly arranged on the upper side of the measuring alarm box. The top of the lifting and swinging assembly is connected to the alarm water level inlet. When the water level in the elevator shaft rises to the alarm water level inlet, it flows into the lifting and swinging assembly along the alarm water level inlet. The gradually increasing gravity of the water drives it to rise and fall while controlling the bottom to swing. The lifting and swinging assembly is provided with a knocking alarm component in a pressing and contacting manner. The lifting and swinging assembly drives the knocking alarm component to emit knocking sounds intermittently in a cycle while the lifting and swinging assembly is running, so as to perform a water accumulation threshold alarm. The process uses the gravity of water to convert into kinetic energy to knock and generate sound, so as to perform a knocking alarm. The whole process adopts mechanical structure coordination, which has extremely high safety and durability compared with electronic equipment.

[0013] A stretch-type opening and closing blocker is elastically swingingly arranged inside the alarm water level inlet. One end of the stretch-type opening and closing blocker facing the inside of the measuring alarm box is connected to the lifting and swinging assembly. In the initial state, the stretch-type opening and closing blocker controls the opening of the alarm water level inlet. In the process of the lifting and swinging assembly being lowered to the maximum position due to the gravity of the water, the stretch-type opening and closing assembly is synchronously driven to swing until the alarm water level inlet is closed. At the same time, when the lifting and swinging assembly moves back and rises, the stretch-type opening and closing assembly moves back synchronously, and then the accumulated water on the outside of the alarm water level inlet enters again, and the above operation is repeated to realize the cyclic lifting and lowering of the lifting and swinging assembly, thereby driving the knocking alarm to continuously and intermittently knock on the alarm.

[0014] Compared with the prior art, the beneficial effects of the present invention are: by utilizing the flow of accumulated water to apply pressure to the piston plate, and then controlling the lifting and swinging assembly to drive the knocking alarm component to knock and make sound in a cycle, thereby utilizing the operation of mechanical transmission to measure and alarm the accumulated water in the elevator shaft, thereby realizing mechanized early warning, and compared with electronic alarms, it has the advantages of durability, safety, and low operating costs.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0030] See also Figure 1-Figure 5 A residential elevator shaft water accumulation measuring and alarming device comprises a measuring and alarming box 10; one side of the measuring and alarming box 10 is fixedly mounted on the elevator shaft wall through a mounting plate 11; the measuring and alarming box 10 is configured as a rectangular sealed structure; a water level measuring line 13 for measuring the accumulated water level is printed on the side of the measuring and alarming box 10 facing the middle of the elevator shaft; an alarm water level inlet 12 is provided at the upper part of the side wall of the measuring and alarming box 10, and a one-way discharge valve port 20 is provided at the lower part;

[0031] The knocking alarm mechanism is installed on the upper side of the measuring alarm box 10. The top of the knocking alarm mechanism is connected to the alarm water level inlet 12. A water collecting tank 19 installed at the bottom of the measuring alarm box 10 is arranged in an interval manner at the bottom. One side of the water collecting tank 19 is connected to the one-way discharge valve port 20. An automatic drainage control system is arranged on the side of the water collecting tank 19 away from the one-way discharge valve port 20. The knocking alarm mechanism includes a lifting and swinging assembly arranged on the upper side of the measuring alarm box 10. The top of the lifting and swinging assembly is connected to the alarm water level inlet 12. When the water level in the elevator shaft rises to the alarm water level, the water level in the elevator shaft rises to the alarm water level. When the water level inlet 12 is reached, the water flows into the lifting and swinging assembly along the alarm water level inlet 12, and the gradually increasing water gravity is used to drive the lifting and lowering of the water while controlling the bottom to swing. The lifting and swinging assembly is provided with a knocking alarm component in a press-contact manner. The lifting and swinging assembly drives the knocking alarm component to emit knocking sounds intermittently in a cycle while the lifting and swinging assembly is running, so as to alarm the water accumulation threshold. The process uses the gravity of the water to convert into kinetic energy to knock and generate sound, so as to alarm with a knocking sound. The whole process adopts mechanical structure coordination, which has extremely high safety and durability compared with electronic equipment.

[0032] A stretch-type opening and closing blocker is elastically swung and arranged inside the alarm water level inlet 12. One end of the stretch-type opening and closing blocker facing the inside of the measuring alarm box 10 is connected to the lifting and swinging assembly. In the initial state, the stretch-type opening and closing blocker controls the alarm water level inlet 12 to open. In the process of the lifting and swinging assembly being dropped to the maximum position by the gravity of the water, the stretch-type opening and closing assembly is synchronously driven to swing until the alarm water level inlet 12 is closed. At the same time, when the lifting and swinging assembly moves back and rises, the stretch-type opening and closing assembly moves back synchronously, and then the accumulated water outside the alarm water level inlet 12 enters again, and the above operation is repeated to realize the cyclic lifting and lowering of the lifting and swinging assembly, thereby driving the knocking alarm component to continuously and intermittently knock on the alarm.

[0033] In the embodiment of the present invention, a plurality of mounting holes are provided on the mounting plate 11, and mounting devices such as expansion bolts are used to mount the mounting plate 11 at a suitable height on the inner wall of the elevator shaft. At the same time, a fluorescent sticker is provided on the water level measuring line 13 to increase the viewing clarity of the water level measuring line 13 in dim light.

[0034] At the same time, a group of alarm sound transmission tubes 14 extending upward are connected to one side of the top of the measurement alarm box 10. The top of the alarm sound transmission tube 14 is extended to a suitable position or height according to the need of amplifying the alarm, so as to ensure that the alarm sound emitted by knocking inside the measurement alarm box 10 can be smoothly received by external staff;

[0035] It should be noted that the volume of the lifting and swinging assembly is reasonably designed to ensure that the accumulated water entering the measuring alarm box 10 can be quickly discharged after it drops to a certain height each time. At the same time, the accumulated water input along the alarm water level inlet 12 can also enter quickly, ensuring that each lifting and lowering of the lifting and swinging assembly can be completed in a relatively short time, thereby smoothly driving the knocking alarm part at the bottom to complete a knocking alarm in a short time.

[0036] In one embodiment of the present invention, the alarm sound transmission tube 14 is made of metal material to ensure that it has a good transmission effect when transmitting sound. The metal material can generally be made of copper, aluminum and other materials, which have good sound transmission and good corrosion resistance.

[0037] Specifically, in order to further improve the effect of transmitting the knocking sound to the outside, a layer of metal plate is attached to the inner wall of the measurement alarm box 10, that is, the sound transmission property of the metal plate is utilized to increase the knocking alarm efficiency.

[0038] As a preferred embodiment of the present invention, refer to Figure 1-Figure 4 , Figure 6 The lifting and swinging assembly includes an L-shaped alarm water input pipe 15 connected to the inner end of the alarm water level inlet 12, the bottom end of the alarm water input pipe 15 is connected to a piston cylinder 16, the bottom end of the piston cylinder 16 is connected to a drainage cylinder 17 with a mesh cylinder structure, and a piston plate 33 is provided inside the piston cylinder 16 in a sliding and lifting manner. The accumulated water input along the alarm water input pipe 15 first falls on the upper side of the piston plate 33, and the piston plate 33 is gradually controlled to fall as the amount of water increases. When the piston plate 33 moves to the inner area of ​​the drainage cylinder 17, the water on the piston plate 33 is quickly discharged by using the fluidity of water under the action of the mesh cylinder structure of the drainage cylinder 17;

[0039] The middle part of the top of the piston plate 33 is fixedly connected to the stretch-type opening and closing blocker through the main pull rope 32, that is, when the piston plate 33 falls, the stretch-type opening and closing blocker is synchronously driven to swing, and the alarm water level inlet 12 is gradually closed. When the piston plate 33 moves back, the stretch-type opening and closing blocker is synchronously expanded to open the alarm water level inlet 12, so as to realize the automatic inflow of the water accumulated outside the alarm water level inlet 12;

[0040] The middle part of the bottom of the piston plate 33 is rotatably connected to a rotating column 34 through a rotating block 36, and a steering rod 37 with a diameter larger than that of the rotating column 34 is installed at the bottom end of the rotating column 34. A group of positioning bases 38 are arranged on the outer side of the steering rod 37. One side of the positioning base 38 is fixed on the inner wall of the measuring alarm box 10. The steering rod 37 is lifted and rotated along the middle of the positioning base 38. A group of sleeve springs 35 are set between the piston plate 33 and the positioning base 38 around the rotating column 34. That is, the resilience of the sleeve springs 35 is utilized to ensure that the piston plate 33 can be quickly controlled to move back after the upper side of the piston plate 33 loses water pressure. At the same time, a circle of steering slide rails 40 connected end to end is provided on the outer wall of the steering rod 37. A leaf spring 39 is detachably installed on the positioning base 38 located just in front of the steering rod 37. A group of sleeves 47 are arranged on the middle part of the leaf spring 39 facing the steering rod 37. One side of the sleeve 47 is fixed to the positioning base 38 through a connecting rod. The sleeve 47 is telescopically provided with a telescopic slide rod 48 radially distributed along the steering rod 37. One end of the telescopic slide rod 48 is placed inside the steering rail 40 to slide, and the other end is in elastic contact with the plate spring 39. That is, when the end of the sleeve 47 is placed inside the steering rail 40 to slide, the elastic push of the end of the sleeve 47 by the pressure rod 49 is coordinated to control the sleeve 47 to slide stably inside the steering rail 40. That is, when the piston plate 33 is subjected to a drop in water pressure, the steering rod 37 is controlled to fall synchronously. At this time, the sleeve 47 slides half the stroke along the trajectory of the steering rail 40, thereby controlling the steering rod 37 to rotate half a circle (180° of the guide plate). At the same time, an extension rod 41 is installed at the middle of the bottom of the steering rod 37. One end of the extension rod 41 is connected to a swinging pressure rod 42. The swinging pressure rod 42 is connected to the knocking alarm part at the bottom in an extrusion contact manner, that is, the swinging pressure rod 42 is intermittently extruded and contacted with the knocking alarm part, thereby cyclically driving the knocking alarm part to operate.

[0041] It should be noted here that by reasonably designing the resistance of the piston plate 33 to descend, it is ensured that the accumulated water input along the alarm water level inlet 12 is within a relatively low content, so that the piston plate 33 can be pressed to fall quickly, and it is ensured that at the moment when the piston plate 33 enters the inner side of the drain cylinder 17, the water volume is relatively small, so that the water can be quickly discharged along the wall of the drain cylinder 17, and then the thrust at the bottom of the piston plate 33 is used to control the piston plate 33 to rise again;

[0042] At the same time, in order to increase the speed of water discharge from the top of the piston plate 33, the top of the piston plate 33 is set to a conical structure, and its structure is used to deposit the water on the piston plate 33 on the top edge, ensuring that the water is discharged the moment the piston plate 33 enters the drain tube 17.

[0043] As a preferred embodiment of the present invention, the knock alarm component includes a connecting block 45 rotatably arranged directly below the steering rod 37, a U-shaped frame 46 is installed at the bottom of the connecting block 45, two groups of inclined swing pressure rods 44 are symmetrically installed on both sides of the connecting block 45, and the top of the swing pressure rod 44 is set to a spherical structure. When the swing pressure rods 44 on both sides are in a symmetrical balance state, the bottom of the swing pressure rod 42 swinging to one side contacts the top of the swing pressure rod 44 on the lower side. When the steering rod 37 swings downward, downward pressure is applied to the swing pressure rod 44. A group of pressure rods 49 are installed on the lower side of the U-shaped frame 46, and a group of sleeve spring rods 50 are arranged in the middle of the pressure rods 49. A pressing groove 51 is opened inside the top of the sleeve spring rod 50, and the pressure rod 49 is placed in the pressing groove 51 to slide. At the same time, an upper fixing ring 52 and a lower fixing ring 53 are fixedly installed on the upper and lower sides of the sleeve spring rod 50, respectively. The sleeve spring rod 50 between the upper fixing ring 52 and the lower fixing ring 53 The upper sleeve is provided with a sleeve spring 54, and a swinging knocking block 55 is installed at the bottom end of the sleeve spring rod 50. A group of U-shaped knocking plates 56 are slidingly and swingingly arranged at the bottom of the swinging knocking block 55. When the swinging pressure rod 42 applies pressure to the swinging pressure rod 44, the pressure rod 49 is synchronously controlled to rise and fall inside the pressing groove 51, and then the elastic effect of the sleeve spring 54 is used to control the swinging knocking block 55 to slide and transfer between the two bottom corners inside the U-shaped knocking plate 56. At the same time, the swinging knocking block 55 and the U-shaped knocking plate 56 are both made of metal material. Due to the rapid conversion of the lifting and lowering of the steering rod 37, the swinging pressure rod 42 follows the lifting and lowering of the steering rod 37, thereby intermittently applying downward pressure to the swinging pressure rods 44 on both sides of the lower part, thereby driving the swinging knocking block 55 at the bottom to knock back and forth on both sides of the inside of the U-shaped knocking plate 56, and utilizing the instantaneous contact between the swinging knocking block 55 and the inner side of the U-shaped knocking plate 56 to knock and make a sound, thereby realizing the function of knocking alarm;

[0044] Specifically, two baffles 43 are symmetrically installed on the measurement alarm box 10 located at the lower part of both sides of the swing pressure rod 44. The baffles 43 are used to limit the swing amplitude of the swing pressure rod 44 to ensure that the swing knocking block 55 can be stably controlled to knock back and forth on both sides inside the U-shaped knocking plate 56.

[0045] As a preferred embodiment of the present invention, a circle of guide plates 18 is installed on the outside of the drainage tube 17 to guide the discharged accumulated water to be concentrated and transferred downward to the water collecting tank 19 for storage. The top of the water collecting tank 19 is set to be open.

[0046] As a preferred embodiment of the present invention, refer to Figure 2 , Figure 8 , Fig.10, the stretching opening and closing stopper includes a sealing plate 28 symmetrically swung by a rotating shaft 29 on the upper and lower sides of the alarm water level inlet 12. When the sealing plates 28 on both sides swing to a vertical angle, the alarm water level inlet 12 is closed. When in a free state, they lie flat on the inner wall of the alarm water level inlet 12. Clockwork springs 30 are arranged at both ends of the rotating shaft 29. When the clockwork springs 30 are in a free state, the sealing plates 28 are controlled to be distributed parallel to the inside of the alarm water level inlet 12. Connecting blocks are installed in the middle of the opposite side of the sealing plates 28 on both sides. The connecting blocks are respectively connected with support ropes 31. The ends of the two sections of the support ropes 31 are commonly connected with a main pull rope 32. The inner end of the main pull rope 32 is connected to the middle of the top of the piston plate 33 along the inside of the alarm water inlet pipe 15. That is, when the piston plate 33 moves up and down, under the connection of the main pull rope 32 and the support rope 31, the resilience of the clockwork spring 30 is cooperated to realize the automatic swing of the sealing plate 28 and the opening and closing control of the alarm water level inlet 12;

[0047] Specifically, a pulley is installed on the inner wall of the alarm water input pipe 15 to maintain the stable and smooth transfer movement of the main pull rope 32.

[0048] As a preferred embodiment of the present invention, refer to Figure 1 , Figure 2 , Figure 7 , Fig. 9 The automatic drainage control system includes a discharge pipe 21 connected to the inner end of the one-way discharge valve port 20, the discharge pipe 21 is placed on one side of the water collecting tank 19, and a solenoid valve 22 is provided on the discharge pipe 21 for pumping the accumulated water in the water collecting tank 19 outward. At the same time, a group of L-shaped pipes 23 are connected to the other side of the water collecting tank 19, and the end of the L-shaped pipe 23 extends to the wall of the measurement alarm box 10. A piston block 24 is slidably provided at the top of the L-shaped pipe 23. An arc-shaped pressure block 25 is installed on the top of the piston block 24 through a connecting rod. A spaced-apart arc-shaped pressure block 25 is provided on the top of the arc-shaped pressure block 25. A push switch 26 is provided, and the top of the push switch 26 is electrically connected to a controller 27. When the accumulated water inside the water collecting tank 19 increases continuously, the control piston block 24 is raised until the arc-shaped pressing block 25 contacts the push switch 26. At this time, the push switch 26 is opened by pressure, and the solenoid valve 22 is electrically connected to the controller 27. At this time, the solenoid valve 22 is driven by the controller 27 to operate, and the accumulated water in the water collecting tank 19 is discharged until the arc-shaped pressing block 25 is separated from the push switch 26. At this time, the solenoid valve 22 stops, so that the accumulated water inside the water collecting tank 19 can be automatically discharged;

[0049] It should be noted that, since the drainage inside the water collecting tank 19 is in the form of local electrical devices, although it may be easily damaged, since the focus of the device is on measurement and alarm, even if the drainage of the water collecting tank 19 fails, it will not affect the measurement and alarm function of the water in the elevator shaft in a short time;

[0050] The push switch 26 is a common electronic switch, which controls the on and off of the circuit by pressing the switch.

[0051] Structure and working principle;

[0052] Push button: Usually a small plastic or metal button that is operated by pressing.

[0053] Contacts: Contains one or more pairs of metal contacts. When the button is pressed, the contacts close and the circuit is connected; when the button is released, the contacts open and the circuit is disconnected.

[0054] Spring: There is usually a spring inside the button to automatically return it to its original position after the button is released.

[0055] 2. Type

[0056] Normally Open (NO): When not pressed, the contacts are open; when pressed, the contacts are closed.

[0057] Normally Closed (NC): When not pressed, the contacts are closed; when pressed, the contacts are open.

[0058] The specific choice depends on the actual situation and will not be elaborated here.

[0059] The working principle of the present invention is: in the idle position of the device, all the driving parts mentioned above, which refer to the power elements, electrical components and the adapted power supply, are connected through wires, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, and does not explain the electrical control. During installation and operation, according to the requirements of the water pressure design threshold, the measuring alarm box 10 is installed at a suitable height on the inner wall of the elevator shaft through the mounting plate 11, and then the top of the alarm sound transmission tube 14 is extended to a suitable position, and then wait for subsequent measurement and use. In normal use, the water level of the elevator shaft can be directly measured through the water level measuring line 13. When the accumulated water level reaches the dangerous threshold alarm water level inlet 12, the accumulated water is transferred to the inside of the measuring alarm box 10 along the alarm water level inlet 12 through the alarm water input pipe 15, and then falls on the upper side of the piston plate 33. As the water continues to increase, the piston plate 33 is forced to fall. At this time, under the connection of the main pull rope 32, the sealing plate 28 is synchronously driven to close the alarm water level inlet 12. When the piston plate 33 falls, , driving the bottom steering rod 37 to move down and rotate, and then move to the inner area of ​​the drain cylinder 17, the water on the top of the piston plate 33 falls rapidly along the drain cylinder 17 and is transferred to the water collecting box 19 through the guide plate 18. In the process of the steering rod 37 falling, the sleeve 47 slides along the inner half axis of the clockwork spring 30. At this time, the steering rod 37 rotates half a circle, and at the same time drives the swing pressure rod 42 to apply downward pressure to the swing pressure rod 44. At this time, under the connection of the U-shaped frame 46, the control pressure rod 49 is pressed down in the pressing groove 51, and then the elasticity of the sleeve spring 54 is Under the action, the swinging knocking block 55 is controlled to swing to the other side of the U-shaped knocking plate 56 to knock. At this time, a sound is generated and then transmitted outward along the alarm sound transmission tube 14 to achieve the alarm function. After the water is discharged from the top of the piston plate 33, under the rebound force of the sleeve spring 35 and the clockwork spring 30, the steering rod 37 moves back and the sealing plate 28 moves back. At this time, the water on the outside of the alarm water level inlet 12 enters again, and the above operation is repeated. At this time, the swinging knocking block 55 is driven to swing to the other side of the U-shaped knocking plate 56 again, thereby realizing intermittent knocking alarm.

[0060] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
