Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent fire hydrants, and specifically relates to an intelligent detection device for fire hydrants. Background Art

[0002] Smart fire hydrants are new firefighting equipment that integrates multiple technologies such as sensing, communication, control, and monitoring on traditional fire hydrants. Smart fire hydrants are installed in open areas such as roadsides, and there is a risk of being hit by cars, causing them to tilt, and the external water outlet may be blocked, so real-time monitoring is required to see if they are tilted.

[0003] The impacted smart fire hydrant may tilt within a 360° range, which makes it difficult to monitor the tilt. The smart fire hydrant is equipped with a shell containing conductive liquid on the outside. When tilted, the conductive liquid flows out and enters the liquid conduction channel, conducting electricity between the two terminals. The circuit board sends the terminal conduction signal to the remote server through the wireless network.

[0004] When the existing intelligent fire hydrant detects a tilted state, conductive liquid will flow out and enter the liquid conduction channel to conduct electricity between the two terminals. After the intelligent fire hydrant is straightened, the conductive liquid will still remain between the two terminals and cannot be reset automatically. Manual cleaning is required, which adds a burden to the reset work after detection. For this reason, we propose a fire hydrant intelligent detection device. Utility Model Content

[0005] The purpose of the utility model is to provide an intelligent detection device for fire hydrants, which can complete the intelligent detection of the skewness of the fire hydrant body. After the fire hydrant body is straightened, it automatically returns to the initial state, which reduces the burden of the reset work after the detection.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A fire hydrant intelligent detection device comprises a fire hydrant body and a communication host fixedly connected to the fire hydrant body, a shell is fixed on the outside of the fire hydrant body at a position below the communication host, a suspension mechanism and a gravity ball are arranged in sequence from top to bottom inside the shell, the gravity ball is fixedly connected to the suspension mechanism, an outer conductive ring is fixed on the inner wall of the shell, an inner conductive ring is axially inserted inside the outer conductive ring, the inner conductive ring and the outer conductive ring are both sleeved on the outside of the gravity ball, and the inner conductive ring and the outer conductive ring are both electrically connected to the communication host, when the fire hydrant body is skewed, the shell drives the outer conductive ring and the inner conductive ring to tilt, The gravity ball is made to abut against and squeeze the inner conductive ring. The inner conductive ring is partially deformed due to the squeezing and the deformed part overlaps with the outer conductive ring to conduct current. Since the outer conductive ring and the inner conductive ring are arranged in a ring shape, they can overlap without dead angles within 360° when squeezed by the gravity ball. The current signal is received through the circuit board to complete the intelligent detection of the skewness of the fire hydrant body, and the abnormal signal of the fire hydrant body is sent to the remote server via the wireless network. Then the staff comes to straighten the fire hydrant body, and the shell drives the outer conductive ring and the inner conductive ring to stand upright, so that the gravity ball automatically returns to its initial state without manual cleaning, which reduces the burden of the reset work after detection.

[0008] Two groups of rubber belts are fixed between the outer edge of the inner conductive ring and the inner edge of the outer conductive ring. The two groups of rubber belts are distributed in a circumferential array. The rubber belts tighten the inner conductive ring in the circumferential direction so that the inner conductive ring can be suspended inside the outer conductive ring. Once squeezed by the gravity ball, the inner conductive ring will stretch the corresponding rubber belt and partially deform to overlap the outer conductive ring. After the gravity ball is detached, the rubber belt will pull the inner conductive ring away from the outer conductive ring to achieve automatic resetting.

[0009] A protective resistor is electrically connected between the outer conductive ring and the communication host. After the inner conductive ring and the outer conductive ring form a closed circuit, current is connected to the protective resistor, which stabilizes the circuit and maintains the stability of the detection process.

[0010] The suspension mechanism includes a plastic ring fixedly connected to the upper wall of the shell, a sling is wound around the plastic ring, and the lower end of the sling is fixedly connected to the upper surface of the gravity ball. The plastic ring and the sling pull the gravity ball upward, so that the gravity ball has a certain degree of freedom. When the shell is skewed, the gravity ball can pull the sling around the plastic ring to swing forward at a certain angle. After the shell is straightened, the gravity ball pulls the sling to swing in the opposite direction to reset.

[0011] A steel ball is arranged in the middle of the gravity ball to increase the weight of the gravity ball so that when the gravity ball swings, sufficient load is applied to the inner conductive ring to fully cause the deformation of the inner conductive ring, which is sufficient for overlapping the outer conductive ring.

[0012] The lower end of the communication host is connected and fixed with a wire tube, the lower end of the wire tube is connected to the inside of the shell, the wire tube is sleeved on the outside of the protective resistor, the wire tube isolates the wires and the protective resistor from rainwater, and sets up a closed wiring channel between the communication host and the shell, so that the detection circuit is in a closed environment.

[0013] The technical effects achieved by this utility model are:

[0014] The present invention provides a practical intelligent detection device for fire hydrants. When the fire hydrant body is skewed, the shell drives the outer conductive ring and the inner conductive ring to tilt, so that the gravity ball abuts against and squeezes the inner conductive ring. The inner conductive ring is partially deformed due to the squeezing, and the deformed part overlaps with the outer conductive ring to conduct current. Since the outer conductive ring and the inner conductive ring are annularly arranged, the two can overlap without dead angles within 360 degrees when squeezed by the gravity ball. The circuit board receives the current signal to complete the intelligent detection of the skewness of the fire hydrant body, and the abnormal signal of the fire hydrant body is sent to the remote server via the wireless network. Then the staff comes to straighten the fire hydrant body, and the shell drives the outer conductive ring and the inner conductive ring to stand upright, so that the gravity ball automatically returns to the initial state without manual cleaning, thereby reducing the burden of resetting work after detection.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-4As shown, a fire hydrant intelligent detection device comprises a fire hydrant body 1 and a communication host 2 fixedly connected to the fire hydrant body 1, referring to the Chinese utility model with publication number CN214860835U, a smart fire hydrant tipping detection device, the communication host 2 is equipped with a circuit board, the circuit board is equipped with a processor, a storage, a temperature sensor, a humidity sensor and a wireless communication module, this technical solution is common knowledge well known to those skilled in the art, and can be fully implemented independently, so it is not drawn in the figure, a shell 3 is fixed to the position below the communication host 2 on the outside of the fire hydrant body 1, the shell 3 can be made of insulating plastic material, a suspension mechanism and a gravity ball 4 are arranged in sequence from top to bottom inside the shell 3, the gravity ball 4 can be made of ceramic material, the gravity ball 4 is fixedly connected to the suspension mechanism, an outer conductive ring 5 is fixed to the inner wall of the shell 3, an inner conductive ring 6 is inserted axially inside the outer conductive ring 5, the inner conductive ring 6 and the outer conductive ring 5 can both be made of conductive metal material, the inner conductive ring 6 and the outer conductive ring 5 are both sleeved on the outside of the gravity ball 4, the inner conductive ring 6 and the outer conductive ring 5 The electric rings 5 ​​are electrically connected to the circuit board in the communication host 2 through wires. The fire hydrant body 1 is placed in an open position on the roadside to connect the power to the communication host 2. When the fire hydrant body 1 is tilted, the shell 3 drives the outer conductive ring 5 and the inner conductive ring 6 to tilt, and the suspension mechanism pulls the gravity ball 4 to suspend in the shell 3. Under the action of gravity, the gravity ball 4 is straight downward, so that the gravity ball 4 abuts against and squeezes the inner conductive ring 6. The inner conductive ring 6 is partially deformed due to the extrusion, and the deformed part overlaps with the outer conductive ring 5, and the current is turned on. Since the outer conductive ring 5 and the inner conductive ring 6 is annularly sleeved, and the two can overlap without dead angles within 360° when squeezed by the gravity ball 4. The circuit board receives the current signal to complete the intelligent detection of the skewness of the fire hydrant body 1, and sends the abnormal signal of the fire hydrant body 1 to the remote server via the wireless network. Then the staff comes to straighten the fire hydrant body 1, and the shell 3 drives the outer conductive ring 5 and the inner conductive ring 6 to stand upright, so that the gravity ball 4 automatically restores the initial state, and the outer conductive ring 5 and the inner conductive ring 6 are separated, without manual cleaning, which reduces the burden of the reset work after detection.

[0023] The distance between the inner conductive ring 6 and the outer conductive ring 5 is no more than 5 mm, and a sufficiently large insulating space is reserved. The length of the inner conductive ring 6 and the length of the outer conductive ring 5 are much larger than the diameter of the gravity ball 4. Even if the gravity ball 4 swings, it can resist the inner conductive ring 6 and the outer conductive ring 5.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, two groups of rubber belts 7 are fixed between the outer edge of the inner conductive ring 6 and the inner edge of the outer conductive ring 5. The two groups of rubber belts 7 are distributed in a circumferential array. The two ends of the rubber belt 7 are respectively bonded to the outer edge of the inner conductive ring 6 and the inner edge of the outer conductive ring 5. The rubber belts 7 tighten the inner conductive ring 6 in the circumferential direction so that the inner conductive ring 6 can be suspended inside the outer conductive ring 5. Once squeezed by the gravity ball 4, the inner conductive ring 6 will stretch the corresponding rubber belt 7 and partially deform to overlap the outer conductive ring 5. After the gravity ball 4 is detached, the rubber belt 7 will pull the inner conductive ring 6 away from the outer conductive ring 5 to achieve automatic resetting.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, a protective resistor 8 is electrically connected between the outer conductive ring 5 and the communication host 2. After the inner conductive ring 6 and the outer conductive ring 5 form a closed circuit, current is turned on for the protective resistor 8, and the protective resistor 8 stabilizes the circuit to maintain the stability of the detection process.

[0026] like Figure 2 and Figure 4 As shown, the suspension mechanism includes a plastic ring 9 fixedly connected to the upper wall of the shell 3, a sling 10 is wound and installed on the plastic ring 9, and the lower end of the sling 10 is fixedly connected to the upper surface of the gravity ball 4. The plastic ring 9 and the sling 10 pull the gravity ball 4 upward, so that the gravity ball 4 has a certain degree of freedom. When the shell 3 is skewed, the gravity ball 4 can pull the sling 10 to swing forward around the plastic ring 9 at a certain angle. After the shell 3 is straightened, the gravity ball 4 pulls the sling 10 to swing in the opposite direction to reset.

[0027] Among them, the slight tilt of the fire hydrant body 1 can be ignored, but when the tilt reaches more than 10°, the gravity ball 4 swings relative to the shell 3, and the gravity ball 4 can completely abut against the inner conductive ring 6 at this time.

[0028] like Figure 2 and Figure 4 As shown, a steel ball 11 is arranged in the middle of the gravity ball 4 to increase the weight of the gravity ball 4 so that when the gravity ball 4 swings, sufficient load is applied to the inner conductive ring 6 to fully cause the deformation of the inner conductive ring 6 to be sufficient for overlapping the outer conductive ring 5.

[0029] like Figure 1 and Figure 2 As shown, the lower end of the communication host 2 is connected and fixed with a wire tube 12, the lower end of the wire tube 12 is connected to the inside of the shell 3, the wire tube 12 is sleeved on the outside of the protective resistor 8, the wire tube 12 is used to isolate the wires and the protective resistor 8 from rainwater, and a closed wiring channel is set up between the communication host 2 and the shell 3, so that the detection circuit is in a closed environment.

[0030] The working principle of the utility model is as follows: when the fire hydrant body 1 is skewed, the shell 3 drives the outer conductive ring 5 and the inner conductive ring 6 to tilt, and the suspension mechanism pulls the gravity ball 4 to be suspended in the shell 3. Under the action of gravity, the gravity ball 4 is straight downward, so that the gravity ball 4 abuts against and squeezes the inner conductive ring 6. The inner conductive ring 6 is squeezed to cause partial deformation and the deformed part overlaps with the outer conductive ring 5, and the current is turned on. Since the outer conductive ring 5 and the inner conductive ring 6 are annularly arranged, the two can overlap without dead angles within 360° when squeezed by the gravity ball 4. The circuit board receives the current signal, completes the intelligent detection of the tilt of the fire hydrant body 1, and sends the abnormal signal of the fire hydrant body 1 to the remote server via the wireless network. Then the staff comes to straighten the fire hydrant body 1, and the shell 3 drives the outer conductive ring 5 and the inner conductive ring 6 to stand upright, so that the gravity ball 4 automatically restores to the initial state, without manual cleaning, which reduces the burden of the reset work after the detection.

[0031] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
