Description

Technical Field

[0001] The invention relates to the field of electric meters, and in particular to an electric meter box. Background Art

[0002] As we all know, the meter box is a device used to install the meter, which is convenient for the power company to record and manage the electricity consumption of the residents. At present, the existing meter boxes on the market are generally composed of a box body, a box door and an electric meter installed in the box. In recent years, with the rapid development of social economy and the continuous increase in electricity consumption, in order to facilitate centralized management, the meter box generally adopts a centralized meter box, that is, multiple meters, multiple wires and multiple switches are arranged in one box.

[0003] With the development and progress of society, the decoration environment of buildings or factories is becoming more and more complex, and various fires occur frequently. Some fires are caused by large fire areas, resulting in the burning of electric meter products. Without cameras, it is impossible to determine the location and cause of the fire. Firefighters can only make manual judgments, which is prone to misjudgment. Some judgment results cause huge losses to the brand image and economy of the electric meter company.

[0004] The patent with application number CN201920420606.9 in the prior art discloses an electric meter box with an alarm function, including a box body, the interior of the box body is divided into a metering chamber and a wiring chamber by a crossbeam, a plurality of partitions are horizontally installed in the metering chamber, each of the partitions is provided with a plurality of wire holes for passing power lines, an electric meter is installed above each of the wire holes, a smoke sensor, a microprocessor and a signal transmitter are installed on the partition, the smoke sensor is electrically connected to the microprocessor, the microprocessor is electrically connected to the signal transmitter and the buzzer respectively, and the buzzer is installed on the box body. Although this patent can sound an alarm when the electric meter catches fire, reminding relevant personnel to eliminate the danger in time, the electric meter box still cannot determine the direction of the fire, and can only be judged manually by firefighters, which is prone to misjudgment.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide an electric meter box to solve the problem in the prior art that the electric meter box still cannot determine the direction of fire and can only be judged manually by firefighters, which is prone to misjudgment.

[0007] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0008] An electric meter box comprises a box body and a box door, wherein the box body is rotatably connected to the box door, an electric meter and a fire direction determination device are installed inside the box body, and the fire direction determination device is used to determine the fire direction of the fire.

[0009] The electric meter box proposed in the present invention can accurately determine the direction of fire after a fire occurs, thereby assisting firefighters in determining the cause of the fire, thereby enhancing the brand image of the electric meter company and reducing the economic losses of the electric meter company.

[0010] Furthermore, the fire direction determination device includes a shell, a partition, at least two temperature control devices and at least two rotating connecting rods, the partition, temperature control device and rotating connecting rod are arranged inside the shell, the partition is arranged below the temperature control device and the rotating connecting rod, the setting direction of the rotating connecting rod on the partition is the same as the setting direction of the temperature control device on the partition, and they correspond one to one; in a normal state, the temperature control device is separately arranged from the partition, the partition is horizontally arranged below the temperature control device and the rotating connecting rod, and the rotating connecting rod is stationary on the partition; in a fire state, the temperature control device that first encounters the fire is fitted with the partition, resulting in the partition being tilted below the temperature control device and the rotating connecting rod, and the rotating connecting rod corresponding to the temperature control device that first encounters the fire will rotate and engage with the partition, and the direction of the rotating connecting rod engaged with the partition is the direction of the fire.

[0011] Furthermore, the temperature control device includes a temperature control shell, in which a spring, an ejection part and a temperature sensing part are arranged. The spring is compressed and arranged above the ejection part, and the temperature sensing part is arranged below the ejection part. The temperature sensing part will melt when encountering a fire. After the temperature sensing part melts, the spring will push the ejection part out of the temperature control shell, and the ejection part will be arranged in contact with the partition after being ejected.

[0012] This arrangement makes it easy for the temperature control device to be set in close contact with the partition when a fire occurs, which is conducive to the inclined setting of the partition, and further facilitates the determination of the direction of the fire.

[0013] Furthermore, the temperature control device and the rotating connecting rod are both arranged on the peripheral side of the partition, the temperature control device is arranged on the outer peripheral side of the partition, and the rotating connecting rod is arranged on the inner peripheral side of the partition.

[0014] This arrangement makes it easy for the temperature control device to be fitted with the partition when a fire occurs, thereby making it easy for the rotating connecting rod to be engaged with the partition when a fire occurs, thereby making it easy to determine the direction of the fire.

[0015] Furthermore, a first clamping structure is provided on the partition, and a second clamping structure is provided on the rotating connecting rod, and the first clamping structure cooperates with the second clamping structure.

[0016] This arrangement facilitates the rotation of the rotating connecting rod corresponding to the temperature control device that first encounters the fire to engage with the partition. After the engagement, the partition cannot return to a horizontal setting state, thereby facilitating the determination of the direction of the fire.

[0017] Furthermore, a supporting device is provided below the partition, and the supporting device is used to support the partition.

[0018] This arrangement improves the stability of the horizontal or inclined arrangement of the partition, thereby making it easier to determine the direction of the fire.

[0019] Furthermore, the supporting device is configured as a spherical surface on a side close to the partition.

[0020] This arrangement can reduce the contact area between the supporting device and the partition, making it easier for the partition to tilt in all directions.

[0021] Furthermore, the supporting device includes a first supporting portion and a second supporting portion, wherein the first supporting portion is arranged below the center position of the partition; and the second supporting portion is arranged on the peripheral side of the first supporting portion.

[0022] This arrangement improves the stability of the horizontal or inclined partition, prevents it from shaking randomly, and makes it easier to determine the direction of fire.

[0023] Furthermore, the rotating connecting rod is mounted on the upper plate of the shell, and in a normal state, the length of the rotating connecting rod is greater than the distance between the partition and the upper plate.

[0024] This arrangement can ensure that the bottom of the rotating connecting rod is tilted on the partition under normal conditions. Only when the partition is tilted in a fire state will the rotating connecting rod rotate and engage with the partition, making it easier to determine the direction of the fire.

[0025] Furthermore, the temperature control device is installed on the upper plate, and in a normal state, the height of the temperature control device is smaller than the distance between the partition and the upper plate.

[0026] This setting can ensure that the temperature control device is separated from the partition under normal conditions. Only in the event of a fire will the temperature control device be placed in contact with the partition, thereby making it easier to determine the direction of the fire.

[0027] The present invention provides an electric meter box, which can accurately determine the direction of fire after a fire occurs, thereby assisting firefighters in determining the cause of the fire, thereby enhancing the brand image of the electric meter company and reducing the economic losses of the electric meter company.

[0041] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0042] Example 1

[0043] This embodiment provides an electric meter box, such as Figure 1 As shown, the electric meter box includes a box body 6 and a box door, the box body 6 is rotatably connected to the box door, and an electric meter 7 and a fire direction determination device 8 are installed inside the box body 6, and the fire direction determination device 8 is used to determine the fire direction of the fire.

[0044] The electric meter box described in this embodiment can accurately determine the direction of fire, thereby assisting firefighters in determining the cause of the fire, thereby enhancing the brand image of the electric meter company and reducing the economic losses of the electric meter company.

[0045] Specifically, Figure 1 As shown, a fireproof plate 61 is arranged inside the box body 6, and the fireproof plate 61 divides the inside of the box body 6 into a first installation area 62 and a second installation area 63. An electric meter 7 is installed in the first installation area 62, and a fire direction determination device 8 is installed in the second installation area 63.

[0046] The fireproof plate 61 is arranged between the first installation area 62 and the second installation area 63 to prevent the fire from spreading to the first installation area 62 after the fire direction determination device 8 in the second installation area 63 catches fire, which is beneficial to prevent the electric meter 7 from catching fire and increase safety.

[0047] Specifically, Figure 2 and Figure 4As shown, the fire starting direction determining device 8 includes a shell 1, a partition 2, at least two temperature control devices 3 and at least two rotating connecting rods 4, the partition 2, the temperature control device 3 and the rotating connecting rod 4 are arranged inside the shell 1, the partition 2 is arranged below the temperature control device 3 and the rotating connecting rod 4, the setting direction of the rotating connecting rod 4 on the partition 2 is the same as the setting direction of the temperature control device 3 on the partition 2, and they correspond one to one; in a normal state, the temperature control device 3 is separated from the partition 2, the partition 2 is horizontally arranged below the temperature control device 3 and the rotating connecting rod 4, and the rotating connecting rod 4 is statically arranged on the partition 2; in a fire state, the temperature control device 3 that first encounters the fire is arranged in contact with the partition 2, resulting in the partition 2 being tilted below the temperature control device 3 and the rotating connecting rod 4, and the rotating connecting rod 4 corresponding to the temperature control device 3 that first encounters the fire will rotate and engage with the partition 2, and the direction of the rotating connecting rod 4 engaged with the partition 2 is the direction of the fire starting.

[0048] In the fire direction determination device 8, the shell 1, partition 2, temperature control device 3 and rotating connecting rod 4 are interrelated and inseparable. Under the joint action of the shell 1, partition 2, temperature control device 3 and rotating connecting rod 4, the fire direction of the fire can be accurately determined, thereby assisting firefighters to determine the cause of the fire, thereby enhancing the brand image of the electric meter company and reducing the economic losses of the electric meter company.

[0049] Specifically, the number of the temperature control devices 3 and the number of the rotating connecting rods 4 are set to be the same.

[0050] This setting can ensure accurate judgment of the fire direction.

[0051] Specifically, there is no limitation on the number of the temperature control device 3 and the rotating connecting rod 4. The temperature control device 3 and the rotating connecting rod 4 can be set to two, three, four, five, six, seven, eight, nine, ten, twelve, fourteen, sixteen, etc.

[0052] Preferably, in this embodiment, the number of the temperature control devices 3 and the rotating connecting rods 4 is set to eight.

[0053] In this embodiment, if Figure 3 As shown, a rotating connecting rod 4 and a temperature control device 3 are arranged in the eight directions of front, rear, left, right, left front, left rear, right front and right rear of the partition 2. That is to say, the rotating connecting rod 4 and the temperature control device 3 correspond one by one in the eight directions of front, rear, left, right, left front, left rear, right front and right rear of the partition 2.

[0054] This arrangement improves the accuracy of determining the direction of fire.

[0055] Specifically, the shape of the partition 2 is not specifically limited. The partition 2 can be set to be a cube, a cuboid, or a cylinder.

[0056] Preferably, in this embodiment, the partition 2 is configured as a cylinder, which facilitates the temperature control device 3 and the rotating connecting rod 4 to be evenly distributed on the circumference of the partition 2 and reduces the space occupied by the partition 2.

[0057] Specifically, Figure 6 and Fig. 9 As shown, the temperature control device 3 includes a temperature control shell 31, in which a spring 32, an ejection portion 33 and a temperature sensing portion 34 are arranged. The spring 32 is compressed and arranged above the ejection portion 33, and the temperature sensing portion 34 is arranged below the ejection portion 33. The temperature sensing portion 34 will melt when encountering a fire. After the temperature sensing portion 34 melts, the spring 32 will push the ejection portion 33 out of the temperature control shell 31. After being ejected, the ejection portion 33 is arranged in contact with the partition 2.

[0058] This arrangement makes it easy for the temperature control device 3 to be arranged in close contact with the partition 2 when a fire occurs, thereby facilitating the determination of the direction of the fire.

[0059] In a normal state, the temperature sensing portion 34 is in a solid state; in a fire state, the temperature sensing portion 34 will melt.

[0060] Specifically, the temperature sensing portion 34 is not limited.

[0061] More specifically, the temperature sensing portion 34 is configured as temperature sensitive particles (not shown in the figure), and the temperature sensitive particles melt after reaching a melting temperature. The melting temperature of the temperature sensitive particles can be set according to actual conditions.

[0062] More specifically, Figure 6 and Figure 7 As shown, the ejection portion 33 includes an ejector plate 331 and an ejector pin 332 . The ejector pin 332 is disposed below the ejector plate 331 , and the temperature sensing particles of the temperature sensing portion 34 are disposed around the ejector pin 332 .

[0063] More specifically, an opening (not shown) is provided at the bottom of the temperature control housing 31, and the opening cooperates with the ejector pin 332. Fig. 9 As shown, the temperature sensing portion 34 will melt when encountering a fire. After the temperature sensing particles of the temperature sensing portion 34 melt, the spring 32 will push the ejector pin 332 out of the temperature control housing 31 . After being pushed out, the ejector pin 332 is arranged in contact with the partition 2 .

[0064] Specifically, Figure 2As shown, the temperature control device 3 and the rotating connecting rod 4 are both arranged on the peripheral side of the partition 2 , the temperature control device 3 is arranged on the outer peripheral side of the partition 2 , and the rotating connecting rod 4 is arranged on the inner peripheral side of the partition 2 .

[0065] This arrangement makes it easy for the temperature control device 3 to be arranged in close contact with the partition 2 when a fire occurs, thereby making it easy for the rotating connecting rod 4 to be engaged with the partition 2 when a fire occurs, thereby making it easy to determine the direction of the fire.

[0066] Specifically, Figure 5 As shown, a first clamping structure 21 is provided on the partition 2. Figure 8 As shown, a second clamping structure 42 is provided on the rotating connecting rod 4. Fig.10 As shown, the first clamping structure 21 cooperates with the second clamping structure 42 .

[0067] This arrangement facilitates the rotation of the rotating connecting rod 4 corresponding to the temperature control device 3 that first encounters the fire to engage with the partition 2. After the engagement, the partition 2 cannot return to the horizontal setting state, thereby facilitating the determination of the direction of the fire.

[0068] Specifically, the first clamping structure 21 is arranged on the rotation track of the rotating connecting rod 4 .

[0069] This arrangement facilitates the rotation of the rotating connecting rod 4 corresponding to the temperature control device 3 that first encounters the fire to engage with the partition 2, thereby facilitating the determination of the ignition direction of the fire.

[0070] More specifically, preferably, in this embodiment, Figure 8 As shown, the first clamping structure 21 is arranged just below the rotating connecting rod 4. This arrangement facilitates the rotating connecting rod 4 corresponding to the temperature control device 3 that first encounters the fire to rotate and clamp with the partition 2, thereby facilitating the determination of the direction of the fire.

[0071] like Fig.10 As shown, the diameter of the first clamping structure 21 is larger than the diameter of the second clamping structure 42, and the diameter of the first clamping structure 21 is smaller than the bottom diameter of the rod body 41. This arrangement can ensure that the second clamping structure 42 is clamped into the first clamping structure 21 and locked, thereby facilitating the determination of the direction of the fire.

[0072] Specifically, there is no specific limitation on the first clamping structure 21 and the second clamping structure 42 , as long as the first clamping structure 21 and the second clamping structure 42 can be clamped together.

[0073] More specifically, preferably, in this embodiment, Figure 5 As shown, the first clamping structure 21 is configured as a clamping hole. Figure 8As shown, the second clamping structure 42 is configured as a clamping column.

[0074] Specifically, Figure 4 and Fig. 9 As shown, a supporting device 5 is provided below the partition 2 , and the supporting device 5 is used to support the partition 2 .

[0075] This arrangement improves the stability of the horizontal or inclined arrangement of the partition 2, thereby making it easier to determine the direction of the fire.

[0076] Specifically, Figure 4 and Fig. 9 As shown, the supporting device 5 is configured as a spherical surface on a side close to the partition 2 .

[0077] This arrangement can reduce the contact area between the supporting device 5 and the partition 2, making it easier for the partition 2 to tilt in all directions.

[0078] Specifically, the supporting device 5 is not specifically limited on the side away from the partition 2. The supporting device 5 can be configured as a cylinder, a cube, or a cuboid on the side away from the partition 2.

[0079] In this embodiment, the supporting device 5 is configured as a cylinder at a side away from the partition plate 2 .

[0080] Specifically, Figure 4 and Fig. 9 As shown, the supporting device 5 includes a first supporting portion 51 and a second supporting portion 52 . The first supporting portion 51 is arranged below the center position of the partition 2 ; and the second supporting portion 52 is arranged on the peripheral side of the first supporting portion 51 .

[0081] This arrangement improves the stability of the partition 2 when it is arranged horizontally or inclined, and prevents it from shaking randomly, thereby making it easier to determine the direction of the fire.

[0082] Specifically, the material of the first support portion 51 is not limited. Preferably, in this embodiment, the material of the first support portion 51 is set to metal. This setting is high temperature resistant and prolongs the service life of the first support portion 51.

[0083] Specifically, the material of the second supporting portion 52 is not limited.

[0084] Preferably, in this embodiment, Figure 4 and Fig. 9 As shown, the material of the second supporting portion 52 is set to be a soft material.

[0085] On the one hand, this arrangement improves the support stability of the partition 2 when the partition 2 is arranged horizontally, and on the other hand, the soft material does not harden when exposed to high temperatures, which facilitates the partition 2 to be arranged at an angle when it encounters the high temperature of a fire.

[0086] Specifically, the soft material is a type of material that does not harden when exposed to high temperatures. In the present invention, the soft material is not specifically limited. Preferably, in this embodiment, the soft material is configured as a sponge. This configuration improves the support stability of the partition 2 when the partition 2 is horizontally arranged, and on the other hand, the sponge does not harden when exposed to high temperatures, which facilitates the partition 2 to be tilted when it encounters the high temperature of a fire.

[0087] Specifically, Figure 2 , Figure 3 , Figure 4 and Fig. 9 As shown, a housing 1 is provided outside the fire direction determination device 8, and the housing 1 is used to protect the internal mechanism from damage; Figure 3 and Figure 8 As shown, the partition 2, the temperature control device 3, the rotating connecting rod 4 and the supporting device 5 are all arranged inside the shell 1, the partition 2 is used to divide the shell 1 into an upper space and a lower space, and the temperature control device 3, the rotating connecting rod 4 and the supporting device 5 are all installed inside the shell 1.

[0088] This arrangement can protect the partition 2, the temperature control device 3, the rotating connecting rod 4 and the supporting device 5 arranged inside the shell 1 from being damaged by fire.

[0089] Specifically, the temperature control device 3 , the rotating connecting rod 4 and the supporting device 5 are all installed inside the shell 1 . The temperature control device 3 and the rotating connecting rod 4 are installed on the upper plate 11 of the shell 1 , and the supporting device 5 is installed on the lower plate 12 of the shell 1 .

[0090] Specifically, the shape of the housing 1 is not specifically limited. The housing 1 can be set to be a cube, a cuboid, or a cylinder.

[0091] Preferably, in this embodiment, the housing 1 is configured as a cylinder, which facilitates the matching of the housing 1 with the partition 2, reduces the volume of the fire direction determination device 8, and facilitates the installation of the fire direction determination device 8.

[0092] Specifically, the material of the housing 1 is not limited.

[0093] The material of the housing 1 is set to be metal or other materials that will not be burned by high temperature.

[0094] Preferably, in this embodiment, the material of the housing 1 is set to metal. This setting can withstand high temperatures and protect the internal mechanism from being damaged.

[0095] Specifically, an observation hole 14 is provided on the housing 1, and a transparent cover (not shown) is installed on the observation hole 14. This arrangement facilitates the observation of the direction of the fire without disassembling the fire direction determination device 8.

[0096] More specifically, Figure 2 , Figure 4 and Fig. 9 As shown, the rotating connecting rod 4 is rotatably connected to the upper plate 11 of the shell 1 . In a normal state, the length of the rotating connecting rod 4 is greater than the distance between the partition 2 and the upper plate 11 .

[0097] This arrangement can ensure that the bottom of the rotating connecting rod 4 is tilted on the partition 2 in a normal state. Only when the partition 2 is tilted in a fire state will the rotating connecting rod 4 rotate and engage with the partition 2, which is convenient for determining the direction of the fire.

[0098] Specifically, the specific manner in which the rotating connecting rod 4 is rotatably connected to the upper plate 11 of the housing 1 is not limited.

[0099] Specifically, a first rotating connection structure 43 is disposed above the rotating connecting rod 4, and a second rotating connection structure (not shown) is disposed on the upper plate 11, and the first rotating connection structure 43 cooperates with the second rotating connection structure.

[0100] Specifically, the first rotating connection structure 43 and the second rotating connection structure are not specifically limited, as long as the first rotating connection structure 43 and the second rotating connection structure can be rotatably connected.

[0101] More specifically, the temperature control device 3 is installed on the upper plate 11 . In a normal state, the height of the temperature control device 3 is smaller than the distance between the partition 2 and the upper plate 11 .

[0102] This arrangement can ensure that the temperature control device 3 is separated from the partition 2 under normal conditions, and only in the event of a fire will the temperature control device 3 be placed in contact with the partition 2, thereby making it easier to determine the direction of the fire.

[0103] The height of the temperature control housing 31 is smaller than the distance between the partition 2 and the upper plate 11 .

[0104] More specifically, Figure 4 and Fig. 9 As shown, the supporting device 5 is installed on the lower plate 12 of the housing 1 .

[0105] The electric meter box includes not only the partition 2, the temperature control device 3, the rotating connecting rod 4, the supporting device 5 and the shell 1, but also other related components. Since the specific structures and specific assembly relationships of the related components are all prior art, they will not be elaborated here.

[0106] In the electric meter box described in this embodiment, under normal conditions, the temperature control device 3 is separated from the partition 2, the partition 2 is horizontally arranged below the temperature control device 3 and the rotating connecting rod 4, the rotating connecting rod 4 is stationary and tilted on the partition 2, and the spring 32 in the temperature control device 3 is in a compressed state; in the event of a fire, the temperature-sensitive particles of the temperature-sensitive part 34 of the temperature control device 3 that first encounters the fire will melt, the spring 32 in the temperature control device 3 will restore to a free state, and the ejector pin 332 will be pushed out of the temperature control housing 31 by the thrust of the spring 32, thereby causing the ejector pin 332 to be pushed out of the temperature control housing 31. The needle 332 is arranged in close contact with the partition 2, which causes the partition 2 to be tilted below the temperature control device 3 and the rotating connecting rod 4. The rotating connecting rod 4 corresponding to the temperature control device 3 that first encounters the fire will rotate due to the influence of gravity, and the second clamping structure 42 of the rotating connecting rod 4 will be clamped with the first clamping structure 21 on the partition 2. Even if other temperature control devices 3 are also activated due to the high temperature of the fire after a period of time, the tilting direction of the partition 2 will no longer change, and the direction of the rotating connecting rod 4 clamped with the partition 2 is the direction of the fire.

[0107] In the electric meter box described in this embodiment, the partition 2, the temperature control device 3, the rotating connecting rod 4, the supporting device 5 and the shell 1 are interrelated and inseparable. Under the joint action of the partition 2, the temperature control device 3, the rotating connecting rod 4, the supporting device 5 and the shell 1, the direction of fire can be accurately determined, thereby assisting firefighters in determining the cause of the fire, thereby enhancing the brand image of the electric meter company and reducing the economic losses of the electric meter company.

[0108] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
