Description

Technical Field

[0001] The present invention relates to the technical field of intelligent water meters, and specifically to an outdoor intelligent water meter that prevents disassembly. Background Art

[0002] With the progress of technology and the popularization of Internet + Smart City, the water meter industry has developed rapidly, and intelligent water meters have gradually replaced traditional mechanical water meters to become the mainstream products in the market. A water meter is an instrument for measuring water flow.

[0003] A patent with the patent announcement number CN217111029U discloses an anti-disassembly intelligent water meter, which includes a base meter, a lead seal protrusion, a Hall element, an electronic controller, and a Hall sensor. When the intelligent water meter is disassembled and the base meter part is separated from the electronic controller part, the Hall sensor will lose the induction signal of the Hall element, and at the same time, an abnormal alarm signal will be sent and transmitted to the electronic controller through a transmission wire harness. The electronic controller will feedback this situation to the background server through wireless remote transmission technology, so that the water supply company can solve the problem in time and reduce losses.

[0004] However, the current intelligent water meters have the following problems: This intelligent water meter only issues an alarm after the water meter is disassembled, and cannot effectively prevent the water meter from being disassembled. Therefore, there will still be situations where users steal water and privately disassemble the electronic controller, and the anti-disassembly effect of the water meter is poor. Therefore, we have proposed an outdoor intelligent water meter that prevents disassembly. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an outdoor intelligent water meter that prevents disassembly, and solves the problem that the intelligent water meter only issues an alarm after the water meter is disassembled, and cannot effectively prevent the water meter from being disassembled. Therefore, there will still be situations where users steal water and privately disassemble the electronic controller, and the anti-disassembly effect of the water meter is poor as described in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An outdoor intelligent water meter that prevents disassembly, including a mounting plate and a water meter main body, the water meter main body is arranged above the mounting plate, and further includes an anti-disassembly device, a protection device, a leak prevention device, and a dehumidification device; Among them, the anti-disassembly device includes two U-shaped mounting brackets, bolts, four L-shaped pads, locking catches, a hollow circular shell, and a groove plate. The two U-shaped mounting brackets are respectively fixedly installed on the top of the mounting plate through bolts, and the two U-shaped mounting brackets are respectively arranged on the left and right sides of the water meter main body. The four L-shaped pads are respectively slidably installed on the front and back of the two U-shaped mounting brackets. The bolts pass through the L-shaped pads. The locking catches are arranged on the side of the L-shaped pads away from the U-shaped mounting brackets. Through holes matching the locking catches are arranged on the outer walls of the U-shaped mounting brackets. The hollow circular shell is fixed in the middle of the top surface of the mounting plate. The groove plate is fixed at the bottom of the water meter main body. The L-shaped pad drives the locking catch to move to the through hole of the U-shaped mounting bracket, and the locking catch is rotated so that the locking catch is snapped into the through hole of the U-shaped mounting bracket, and the locking catch is stuck with the thread on the outer wall of the bolt, so that the bolt is not easily disassembled privately by users.

[0007] Preferably, the anti-disassembly device further includes four L-shaped push plates, two toothed plates, triangular blocks, and ejector rods. The four L-shaped push plates are respectively slidably installed on the front and back of the left and right inner walls of the hollow circular shell, and springs are arranged between the tops of the L-shaped push plates and the hollow circular shell. The L-shaped push plates are located on the movement track of the bolts. The ejector rods are fixed on the tops of the L-shaped push plates. The two toothed plates are both slidably installed inside the hollow circular shell, and springs are arranged between the toothed plates and the inner walls of the hollow circular shell. The triangular blocks are fixed on the sides of the toothed plates away from the groove plate. The ejector rods are in contact with the inclined surfaces of the triangular blocks. The toothed plates are snap-connected to the grooves of the groove plate. At the same time, the bolts push the L-shaped pads downward, and the L-shaped pads drive the ejector rods to move synchronously. The ejector rods abut against the inclined surfaces of the triangular blocks and push the toothed plates to snap into the grooves of the groove plate, so as to further fix the water meter main body, thereby improving the anti-disassembly protection performance of the water meter main body.

[0008] Preferably, the protection device includes four elastic telescopic rods, a U-shaped frame, a protection plate, rubber wheels, and four abutting rods. The four elastic telescopic rods are respectively fixed at the four corners of the top of the mounting plate. The U-shaped frame is fixed at the top of the telescopic ends of the elastic telescopic rods. The protection plate is hinged to the left inner wall of the U-shaped frame. The protection plate forms a protection on the top surface of the water meter main body, thus avoiding the problem that the water meter main body is damaged due to external force collision. At the same time, under the action of the elastic force of the elastic telescopic rods, the elastic telescopic rods buffer the protection plate, thereby improving the protection effect of the protection plate on the water meter main body. The rubber wheels are fixed at the hinge shafts of the protection plate. The four abutting rods are all fixed at the top of the mounting plate. The four abutting rods are located on the side of the elastic telescopic rods close to the center of the U-shaped frame. The outer wall of the rubber wheel contacts the left outer wall of the left abutting rod. When the staff needs to read the water meter main body, press down the U-shaped frame. The U-shaped frame drives the rubber wheel to move downward along the outer wall of the abutting rod through the protection plate. The abutting rod abuts the rubber wheel and causes it to rotate. The rubber wheel drives the protection plate to flip upward. The protection plate no longer covers the water meter main body, so that the protection plate can not only protect the water meter main body but also facilitate the user to read the meter.

[0009] Preferably, the protection device further includes a collection box. The collection box is fixed at the top left of the protection plate. At the same time, when the protection plate is turned up, the impurities on the surface of the protection plate will fall into the collection box for collection, thus facilitating the subsequent cleaning of the impurities by the user.

[0010] Preferably, the water mist removal device includes two cross plates, a V-shaped scraper, and a hinge rod. The two cross plates are respectively fixed between two abutting rods on one side. The V-shaped scraper is slidably mounted on the top of the cross plates. The hinge rod is hinged between the top of the cross plates and the bottom of the U-shaped frame. The U-shaped frame pushes the hinge rod to drive the V-shaped scraper to scrape the water mist and impurities generated on the surface of the water meter main body off the water meter main body. At the same time, the V-shaped inclined surface of the V-shaped scraper will guide the water mist and impurities to both sides of the water meter main body, thereby reducing the amount of impurities remaining on the surface of the water meter main body, so that the water meter main body is convenient for the user to read the meter.

[0011] Preferably, the water mist removal device further includes a pressing plate, a spring plate, and an abutting plate. The pressing plate is slidably mounted between two abutting rods on one side. The spring plate is arranged between the bottom of the pressing plate and the top of the mounting plate. The abutting plate is fixed on the side of the pressing plate away from the water meter main body. The two ends of the V-shaped scraper are provided with convex blocks. The top of the abutting plate is located on the movement track of the convex blocks of the V-shaped scraper. At the same time, the convex blocks of the V-shaped scraper push the abutting plate to drive the pressing plate to move downward. The pressing plate pushes the spring plate to fan the air around the water meter main body, thereby promoting the volatilization of the water vapor on the surface of the water meter main body, and thus reducing the probability of generating water mist on the surface of the water meter main body.

[0012] Preferably, the leak-proof device includes two through-port plates, a U-shaped pressing ring, a rubber ring, a through-port sliding plate, a U-shaped push rod and a trapezoidal block. The two through-port plates are respectively fixed on the left and right sides of the top of the mounting plate. The U-shaped pressing ring penetrates and is slidably mounted on the side of the through-port plate close to the water meter main body. The through-port sliding plate is fixed on the side of the U-shaped pressing ring away from the water meter main body, and a spring is provided between the through-port sliding plate and the through-port plate. The rubber ring is arranged between the U-shaped pressing ring and the through-port plate. The trapezoidal block is fixed on the lower part of the outer wall of the through-port sliding plate. The U-shaped push rod is fixed on the side of the L-shaped cushion plate away from the water meter main body. The side of the U-shaped push rod away from the L-shaped cushion plate contacts the inclined surface of the trapezoidal block. The L-shaped cushion plate drives the U-shaped push rod to move downward. The U-shaped push rod pushes the trapezoidal block to drive the through-port sliding plate to move away from the water meter main body. The through-port sliding plate pulls the U-shaped pressing ring to squeeze the rubber ring. The rubber ring deforms under force and fits tightly against the interface of the water meter main body and the external pipeline, thereby improving the sealing performance between the interface of the water meter main body and the external pipeline and avoiding the problem of easy water leakage at the interface of the water meter main body and the external pipeline.

[0013] The present invention provides an anti-disassembly outdoor intelligent water meter. It has the following beneficial effects: (1) Through the setting of the anti-disassembly device, the locking buckle is inserted into the through-hole of the U-shaped mounting frame, and the thread of the locking buckle is stuck with the outer wall of the bolt, so that the bolt is not easily disassembled privately by users; at the same time, the bolt, the L-shaped cushion plate, the ejector rod and the triangular block cooperate to push the convex tooth plate into the card slot of the card slot plate, so as to further fix the water meter main body, thereby improving the anti-disassembly protection performance of the water meter main body.

[0014] (2) Through the setting of the protection device, the protection plate forms a protection on the top surface of the water meter main body, thus avoiding the problem that the water meter main body is damaged due to external collision; at the same time, under the action of the elastic force of the elastic telescopic rod, the elastic telescopic rod buffers the protection plate, thereby improving the protection effect of the protection plate on the water meter main body; when the staff needs to read the water meter main body, the U-shaped frame, the elastic telescopic rod, the protection plate and the rubber wheel cooperate to drive the protection plate to turn up, and the protection plate no longer covers the water meter main body, so that the protection plate can not only protect the water meter main body but also facilitate users to read the meter.

[0015] (3) The present invention provides a demisting device so that the U-shaped frame, the hinged rod, the V-shaped scraper and the cross plate cooperate to enable the V-shaped scraper to scrape the water mist and impurities generated on the surface of the water meter body away from the water meter body. At the same time, the V-shaped slope of the V-shaped scraper guides the water mist and impurities to the two sides of the water meter body, thereby reducing the amount of impurities remaining on the surface of the water meter body, so that the water meter body is convenient for users to read; at the same time, the V-shaped scraper, the contact plate and the pressure plate cooperate to drive the spring plate to fan the air around the water meter body, thereby promoting the volatilization of water vapor on the surface of the water meter body, thereby reducing the probability of water mist on the surface of the water meter body.

[0016] (4) The present invention provides a leak-proof device so that the L-shaped pad, U-shaped push rod, trapezoidal block, through-opening slide plate and U-shaped pressure ring cooperate to squeeze the rubber ring. The rubber ring is deformed by the force and adheres closely to the interface of the water meter body and the external pipe, thereby improving the sealing performance between the interface of the water meter body and the external pipe, and avoiding the problem of water leakage at the interface of the water meter body and the external pipe.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Embodiment 1

[0020] Please refer to Figures 1-5 , the present invention provides a technical solution: an anti-disassembly outdoor intelligent water meter, including a mounting plate 1 and a water meter main body 2. The water meter main body 2 is arranged above the mounting plate 1, and further includes an anti-disassembly device 3 and a protection device 4; Among them, the anti-disassembly device 3 includes two U-shaped mounting brackets 31, bolts 311, four L-shaped pads 32, a locking buckle 321, a hollow circular shell 33 and a slot plate 35. The two U-shaped mounting brackets 31 are respectively fixedly installed on the top of the mounting plate 1 through bolts 311, and the two U-shaped mounting brackets 31 are respectively arranged on the left and right sides of the water meter main body 2. The four L-shaped pads 32 are respectively slidably installed on the front and back of the two U-shaped mounting brackets 31. The bolt 311 passes through the L-shaped pad 32. The locking buckle 321 is arranged on the side of the L-shaped pad 32 away from the U-shaped mounting bracket 31. A through hole matching the locking buckle 321 is arranged on the outer wall of the U-shaped mounting bracket 31. The hollow circular shell 33 is fixed in the middle of the top surface of the mounting plate 1, and the slot plate 35 is fixed at the bottom of the water meter main body 2. The L-shaped pad 32 drives the locking buckle 321 to move to the through hole of the U-shaped mounting bracket 31, and the locking buckle 321 is rotated so that the locking buckle 321 is stuck into the through hole of the U-shaped mounting bracket 31, and the thread of the locking buckle 321 is stuck to the outer wall of the bolt 311, so that the bolt 311 is not easily disassembled privately by users.

[0021] The anti-disassembly device 3 further includes four L-shaped push plates 34, two toothed plates 36, a triangular block 37 and a push rod 38. The four L-shaped push plates 34 are respectively slidably installed on the front and back of the left and right inner walls of the hollow circular shell 33, and a spring is arranged between the top of the L-shaped push plate 34 and the hollow circular shell 33. The L-shaped push plate 34 is located on the movement track of the bolt 311. The push rod 38 is fixed on the top of the L-shaped push plate 34. The two toothed plates 36 are both slidably installed inside the hollow circular shell 33, and a spring is arranged between the toothed plate 36 and the inner wall of the hollow circular shell 33. The triangular block 37 is fixed on the side of the toothed plate 36 away from the slot plate 35. The push rod 38 contacts the inclined surface of the triangular block 37. The toothed plate 36 is clamped with the slot of the slot plate 35. At the same time, the bolt 311 pushes the L-shaped pad 32 to move downward, and the L-shaped pad 32 drives the push rod 38 to move synchronously. The push rod 38 touches the inclined surface of the triangular block 37 and pushes the toothed plate 36 to be stuck into the slot of the slot plate 35, so as to further fix the water meter main body 2, thereby improving the anti-disassembly protection performance of the water meter main body 2.

[0022] The protection device 4 includes four elastic telescopic rods 41, a U-shaped frame 42, a protection plate 43, rubber wheels 44 and four abutting rods 45. The four elastic telescopic rods 41 are respectively fixed at the four corners of the top of the mounting plate 1. The U-shaped frame 42 is fixed at the top of the telescopic ends of the elastic telescopic rods 41. The protection plate 43 is hinged to the left side inner wall of the U-shaped frame 42. The protection plate 43 forms a protection on the top surface of the water meter main body 2, thus avoiding the problem that the water meter main body 2 is damaged due to external force collision; at the same time, under the action of the elastic force of the elastic telescopic rods 41, the elastic telescopic rods 41 buffer the protection plate 43, thereby improving the protection effect of the protection plate 43 on the water meter main body 2. The rubber wheels 44 are fixed at the hinge shaft of the protection plate 43. The four abutting rods 45 are all fixed at the top of the mounting plate 1. The four abutting rods 45 are located on the side of the elastic telescopic rods 41 close to the center of the U-shaped frame 42. The outer wall of the rubber wheel 44 is in contact with the left outer wall of the left abutting rod 45. When the staff needs to read the water meter main body 2, press down the U-shaped frame 42. The U-shaped frame 42 drives the rubber wheel 44 to move downward along the outer wall of the abutting rod 45 through the protection plate 43. The abutting rod 45 abuts against the rubber wheel 44 and rotates. The rubber wheel 44 drives the protection plate 43 to flip upward. The protection plate 43 no longer covers the water meter main body 2, so that the protection plate 43 can not only protect the water meter main body 2 but also facilitate the user to read the meter.

[0023] The protection device 4 further includes a collection box 46. The collection box 46 is fixed at the left top of the protection plate 43. At the same time, when the protection plate 43 is turned up, the impurities on the surface of the protection plate 43 will fall into the collection box 46 for collection, thus facilitating the subsequent cleaning of the impurities by the user.

[0024] During use, place the water meter main body 2 on the mounting plate 1, so that the water meter main body 2 drives the clamping groove plate 35 to be stuck on the top of the hollow circular shell 33. Install the U-shaped mounting frame 31 on the mounting plate 1 through the bolt 311. The U-shaped mounting frame 31 fixes the water meter main body 2 on the mounting plate 1. At the same time, the bolt 311 pushes the L-shaped cushion plate 32 to move downward. The L-shaped cushion plate 32 drives the locking buckle 321 to move to the through hole of the U-shaped mounting frame 31. Rotate the locking buckle 321 so that the locking buckle 321 is stuck into the through hole of the U-shaped mounting frame 31, and the thread of the locking buckle 321 is stuck with the outer wall of the bolt 311, so that the bolt 311 is not easily disassembled by the user privately; at the same time, when the bolt 311 is screwed downward, the bolt 311 pushes the L-shaped cushion plate 32 to move downward. The L-shaped cushion plate 32 drives the ejector rod 38 to move synchronously. The ejector rod 38 abuts against the inclined surface of the triangular block 37 and pushes the convex tooth plate 36 to be stuck into the clamping groove of the clamping groove plate 35, so as to further fix the water meter main body 2, thereby improving the anti-disassembly protection performance of the water meter main body 2.

[0025] The protective plate 43 forms a protection on the top surface of the water meter main body 2, thus avoiding the problem that the water meter main body 2 is damaged due to external force collision; at the same time, under the action of the elastic telescopic rod 41, the elastic telescopic rod 41 buffers the impact on the protective plate 43, thereby improving the protection effect of the protective plate 43 on the water meter main body 2; when the staff needs to read the water meter main body 2, press down the U-shaped frame 42, and the U-shaped frame 42 presses the telescopic end of the elastic telescopic rod 41 to move downward. The U-shaped frame 42 drives the rubber wheel 44 to move downward along the outer wall of the contact rod 45 through the protective plate 43. Under the friction force between the rubber wheel 44 and the contact rod 45, the contact rod 45 is made to contact and rotate the rubber wheel 44. The rubber wheel 44 drives the protective plate 43 to turn upward, and the protective plate 43 no longer covers the water meter main body 2, so that the protective plate 43 can not only protect the water meter main body 2 but also facilitate the user to read the meter. At the same time, when the protective plate 43 is turned up, the impurities on the surface of the protective plate 43 will fall into the collection box 46 for collection, so as to facilitate the subsequent cleaning of the impurities by the user. Embodiment 2

[0026] Please refer to Figures 1-7 , on the basis of Embodiment 1, in this embodiment, a leak-proof device 5 and a water mist removal device 6 are further included; The water mist removal device 6 includes two cross plates 61, a V-shaped scraper 62 and a hinge rod 63. The two cross plates 61 are respectively fixed between the two contact rods 45 on one side. The V-shaped scraper 62 is slidably installed on the top of the cross plate 61. The hinge rod 63 is hinged between the top of the cross plate 61 and the bottom of the U-shaped frame 42. The U-shaped frame 42 pushes the hinge rod 63 to drive the V-shaped scraper 62 to scrape the water mist and impurities generated on the surface of the water meter main body 2 away from the water meter main body 2. At the same time, the V-shaped inclined surface of the V-shaped scraper 62 will guide the water mist and impurities to both sides of the water meter main body 2, thereby reducing the amount of impurities remaining on the surface of the water meter main body 2, so that the water meter main body 2 is convenient for the user to read the meter.

[0027] The water mist removal device 6 further includes a pressing plate 64, a spring plate 65 and a contact plate 66. The pressing plate 64 is slidably installed between the two contact rods 45 on one side. The spring plate 65 is arranged between the bottom of the pressing plate 64 and the top of the mounting plate 1. The contact plate 66 is fixed on the side of the pressing plate 64 away from the water meter main body 2. Convex blocks are provided at both ends of the V-shaped scraper 62. The top of the contact plate 66 is located on the movement track of the convex blocks of the V-shaped scraper 62. At the same time, the convex blocks of the V-shaped scraper 62 push the contact plate 66 to drive the pressing plate 64 to move downward. The pressing plate 64 pushes the spring plate 65 to fan the air around the water meter main body 2, thereby promoting the volatilization of the water vapor on the surface of the water meter main body 2, and thus reducing the probability of generating water mist on the surface of the water meter main body 2.

[0028] The leak-proof device 5 includes two through-port plates 51, a U-shaped pressing ring 52, a rubber ring 53, a through-port sliding plate 54, a U-shaped push rod 55 and a trapezoidal block 56. The two through-port plates 51 are respectively fixed on the left and right sides of the top of the mounting plate 1. The U-shaped pressing ring 52 penetrates and is slidably mounted on the side of the through-port plate 51 close to the water meter main body 2. The through-port sliding plate 54 is fixed on the side of the U-shaped pressing ring 52 away from the water meter main body 2, and a spring is provided between the through-port sliding plate 54 and the through-port plate 51. The rubber ring 53 is arranged between the U-shaped pressing ring 52 and the through-port plate 51. The trapezoidal block 56 is fixed below the outer wall of the through-port sliding plate 54. The U-shaped push rod 55 is fixed on the side of the L-shaped cushion plate 32 away from the water meter main body 2. The side of the U-shaped push rod 55 away from the L-shaped cushion plate 32 contacts the inclined surface of the trapezoidal block 56. The L-shaped cushion plate 32 drives the U-shaped push rod 55 to move downward. The U-shaped push rod 55 pushes the trapezoidal block 56 to drive the through-port sliding plate 54 to move away from the water meter main body 2. The through-port sliding plate 54 pulls the U-shaped pressing ring 52 to squeeze the rubber ring 53. The rubber ring 53 deforms under force and adheres tightly to the interface of the water meter main body 2 and the external pipeline, thereby improving the sealing performance between the interface of the water meter main body 2 and the external pipeline and avoiding the problem of easy water leakage at the interface of the water meter main body 2 and the external pipeline.

[0029] During use, when the L-shaped cushion plate 32 moves downward, the L-shaped cushion plate 32 drives the U-shaped push rod 55 to move downward. The U-shaped push rod 55 pushes the inclined surface of the trapezoidal block 56 to drive the through-port sliding plate 54 to move away from the water meter main body 2. The through-port sliding plate 54 pulls the U-shaped pressing ring 52 to move. The U-shaped pressing ring 52 squeezes the rubber ring 53. The rubber ring 53 deforms under force and adheres tightly to the interface of the water meter main body 2 and the external pipeline, thereby improving the sealing performance between the interface of the water meter main body 2 and the external pipeline and avoiding the problem of easy water leakage at the interface of the water meter main body 2 and the external pipeline. When the U-shaped frame 42 moves downward, the U-shaped frame 42 pushes the articulated rod 63 to drive the V-shaped scraper 62 to slide along the top of the cross plate 61. The V-shaped scraper 62 will scrape the water mist and impurities generated on the surface of the water meter main body 2 away from the water meter main body 2. At the same time, the V-shaped inclined surface of the V-shaped scraper 62 will guide the water mist and impurities to both sides of the water meter main body 2, thereby reducing the amount of impurities remaining on the surface of the water meter main body 2 and making it convenient for users to read the water meter. At the same time, when the V-shaped scraper 62 moves, the convex block of the V-shaped scraper 62 pushes the contact plate 66 to drive the pressing plate 64 to move downward. The pressing plate 64 will squeeze the elastic plate 65. When the convex block of the V-shaped scraper 62 does not push the contact plate 66, under the elastic force of the elastic plate 65, the elastic plate 65 resets. During the deformation and reset process of the elastic plate 65, it will fan the air around the water meter main body 2, thereby promoting the volatilization of the water vapor on the surface of the water meter main body 2 and reducing the probability of water mist generation on the surface of the water meter main body 2.
