Description

Technical Field

[0001] The present invention relates to the technical field of fire extinguishers, and more particularly to an intelligent fire extinguisher inspection device for a substation. Background Art

[0002] Fire extinguisher boxes are commonly used to store fire extinguishers. They primarily protect against dust and prevent extinguishers from being accidentally knocked over. During actual use, fire extinguishers require regular inspections to prevent them from deteriorating and becoming ineffective. Due to the large number of fire extinguishers in substations, inspections are typically conducted by designated personnel. Furthermore, due to the large size of substations, some personnel who fail to adhere to regulations often have other personnel sign on their behalf, leading to management confusion. Furthermore, fire extinguishers can become ineffective due to prolonged storage, making it difficult to detect ineffective extinguishers during inspections.

[0003] Chinese patent publication number CN110711338A, publication date January 21, 2020, the name of the invention is fire extinguisher inspection record card fixing device, the application discloses a fire extinguisher inspection device, which makes it easy to replace the record card during the inspection process by setting a fixing rod and a fixing column; although the above structure can very conveniently prevent the record card, it cannot avoid the phenomenon of signing on behalf of others or signing randomly, and it is not convenient for unified management of fire extinguishers. Summary of the Invention

[0004] The present invention overcomes two technical problems in the prior art: first, the traditional recording card method is used for recording during fire extinguisher inspection, which cannot avoid the phenomenon of staff signing on behalf of others or signing randomly, resulting in chaotic fire extinguisher management; second, it is inconvenient to check out invalid fire extinguishers. The present invention provides an intelligent fire extinguisher inspection device for substations, which can avoid the phenomenon of staff signing randomly or signing on behalf of others by setting a fingerprint card punching device, and can record each inspection record, facilitating fire extinguisher management; at the same time, invalid fire extinguishers can be discovered in a timely manner.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: a substation intelligent fire extinguisher inspection device, comprising:

[0006] Fire extinguisher box, where the fire extinguisher is placed;

[0007] The recorder is provided with a fingerprint sensing area and an LCD display, and a stretchable connecting belt is provided on the back of the recorder.

[0008] In the present invention, the recorder is provided with a fingerprint sensing area and a liquid crystal display screen. The fingerprint sensing area can recognize and record fingerprints, and the liquid crystal display screen can display the inspection status, inspector, and inspection date. The fingerprint sensing area recognizes the staff member's fingerprint, clocks in and out the inspector, and records the inspector's inspection time and inspection information. This effectively prevents the phenomenon of staff members signing in on behalf of others or signing in arbitrarily, while facilitating the management of fire extinguishers. In addition, a stretchable connecting strap is provided on the back of the recorder, and the recorder is fixed to the fire extinguisher via the stretchable connecting strap, making the recorder very convenient to install on the fire extinguisher.

[0009] Preferably, the recorder is provided with an information recording module, which can record the time of each inspection and the information of the inspector.

[0010] The information recording module can record the time of each inspection and the information of the inspection personnel, as well as the records of previous inspections by staff.

[0012] By providing a detection device and observing the position of the floating block relative to the fixed ring, the weight of the fire extinguisher can be detected, making it very convenient to discover an invalid fire extinguisher. Moreover, since even fire extinguishers of the same model have different weights, the fixed ring and the floating block are coordinated so that each time a new fire extinguisher is placed on the mounting seat, the change in the liquid level height of the display column is equivalent to a "zeroing" process, so that the new fire extinguisher can correspond to a new liquid level height. Thereafter, by observing the position between the floating block and the fixed ring, the weight reduction of the fire extinguisher can be observed, making the detection of the weight change of the fire extinguisher more accurate.

[0013] Preferably, the outer side wall of the display column is provided with an adjustment block cooperating with the fixing ring, and the adjustment block and the fixing ring are attracted to each other by magnetic force, so that the fixing ring can be fixed in the display column.

[0014] The adjusting block is used to fix the position of the fixing ring so that the fixing ring will not fall due to its own gravity.

[0015] Preferably, the outer side wall of the display column is provided with a slide groove along its length direction, and the adjustment block is arranged in the slide groove.

[0016] The adjustment block is arranged in the slide groove so that the position of the adjustment block will not be moved due to accidental collision.

[0017] Preferably, a floating hole is provided through the floating block, and the upper end of the connecting rod is threadedly connected to the floating hole.

[0018] The threaded connection between the connecting rod and the floating block allows the distance between the limiting plate and the floating block to be adjusted, thereby adjusting the measured stroke of the fire extinguisher and making it suitable for different models of fire extinguishers.

[0019] Preferably, an abutment spring is provided in the elastic sealing bag, the upper end of the abutment spring abuts against the bottom of the mounting seat, and the lower end of the abutment spring abuts against the bottom of the mounting chamber.

[0021] Preferably, a through hole is provided at the top end of the display column, a sealing head is provided in the through hole to match it, and a sealing hole is provided through the sealing head.

[0022] The sealing hole is used to connect the air between the display column and the outside world, and the setting of the sealing head makes it easy to remove the weight confirmation meter from the display column, making it convenient to adjust the range of the weight confirmation machine.

[0023] Preferably, a partition is provided at the bottom of the fire extinguisher box, two installation chambers are formed on both sides of the partition, and a mounting seat is provided in each of the two installation chambers.

[0024] It is provided with two mounting seats so that two detection devices for detecting weight can be installed and two weight gauges can be conveniently placed at the same time.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) By setting up a recorder, it is easy to record inspection information, effectively preventing staff from signing on behalf of others or signing randomly, and facilitating the management of fire extinguishers;

[0027] (2) It can accurately detect the change in the weight of the fire extinguisher, so that the failed fire extinguisher can be discovered in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0036] Example 1: A smart fire extinguisher inspection device for a substation, comprising a fire extinguisher box 1 and a recorder 2:

[0037] The fire extinguisher 5 is placed in the fire extinguisher box;

[0038] The recorder is equipped with a fingerprint sensor area 21 and an LCD screen 22. The fingerprint sensor area can recognize and record fingerprints, and the LCD screen can display the inspection status, inspector, and inspection date. A stretchable connecting strap 23 is provided on the back of the recorder, which is used to secure the recorder to the fire extinguisher. The recorder is equipped with an information recording module that can record the time of each inspection and the information of the inspector, as well as the records of previous inspections by staff. The recorder is also equipped with a keypad 24, which allows inspectors to easily access inspection information.

[0039] When in use, the fingerprint of the inspector of the work unit is first entered into the system. Later, during the inspection process, the fingerprint of the staff is identified through the fingerprint sensing area, the inspector is clocked in, and the inspection time and inspection information of the inspector are recorded; this effectively prevents the phenomenon of staff signing in on behalf of others or signing randomly, and facilitates the management of fire extinguishers.

[0040] Example 2: Reference Figures 1 to 3 As shown, this embodiment is similar in structure to embodiment 1, except that a partition 11 is provided at the bottom of the fire extinguisher box, which isolates the bottom of the fire extinguisher box, so that two installation chambers 12 are formed on both sides of the partition, and mounting seats 13 are slidably provided in both installation chambers, and the fire extinguisher is placed on the mounting seats.

[0041] The fire extinguisher box is also equipped with a detection device 3 for detecting the weight of the fire extinguisher. The detection device includes an elastic sealing bag 31 installed between the bottom of the mounting seat and the bottom of the mounting chamber, and a display column 32 installed outside the fire extinguisher box. The elastic sealing bag contains an abutment spring 311, the upper end of which abuts the bottom of the mounting seat, and the lower end of which abuts the bottom of the mounting chamber. The elastic sealing bag is filled with liquid, which in this embodiment is water. The lower end of the display column is connected to the elastic sealing bag. The display column is made of a transparent material, such as transparent plastic or transparent glass. In this embodiment, the display column is made of transparent plastic. A weight confirmation meter 4 is installed in the display column. The weight confirmation meter includes a fixed ring 41 and a floating block 42. A connecting rod 43 is installed at the bottom of the floating block 42. The connecting rod 43 passes through the fixing ring below and has a limit plate 44 at its end. The buoyancy of the floating block is greater than the combined weight of the floating block, the connecting rod, and the fixing ring, and the weight of the fixing ring is greater than its buoyancy.

[0042] The outer wall of the display column is equipped with an adjustment block 45 that cooperates with the fixing ring. The adjustment block and the fixing ring are attracted to each other by magnetic force, so that the fixing ring can be fixed to the inner wall of the display column. The outer wall of the display column is provided with a sliding groove 323 along its length, and the adjustment block is mounted in the sliding groove.

[0043] A through-hole 321 is provided at the top of the display column, and a sealing head 322 is provided in the through-hole to match it. A sealing hole is provided through the sealing head, and the sealing hole is used to connect the air between the display column and the outside world; the setting of the sealing head makes it easy to remove the weight confirmation meter from the display column.

[0044] When inspecting a fire extinguisher, weighing is usually used to determine whether the fire extinguisher is invalid. Therefore, the present embodiment also uses a weighing detection method to inspect the fire extinguisher.

[0045] The working principle of this embodiment is as follows: first, place the fire extinguisher on the mounting base, remove the adjustment block, and then observe the liquid level in the display column. At this time, the floating block floats on the liquid surface, while the fixing ring is suspended on the limit plate. Then, install the adjustment block so that the adjustment block and the fixing block attract each other, causing the fixing ring to be fixedly attached to the inner wall of the display column. When the fire extinguisher fails, the carbon dioxide content in the fire extinguisher decreases, causing the fire extinguisher to lose weight. This weight decreases, causing the contact spring to expand upward, increasing the volume of the elastic sealing airbag, causing the liquid level in the display column to drop. This causes the floating head to move downward as the liquid level drops, and also drives the connecting rod connected to the floating head downward. Because the fixing ring is fixed to the side wall of the display column through magnetic attraction with the adjustment block, it does not drop as the liquid level in the display column drops. Therefore, as the weight of the fire extinguisher decreases, the liquid level in the display column also continuously decreases. When the floating block abuts the upper end of the fixing ring, the fire extinguisher has reached a failure state and should be replaced.

[0046] In this embodiment, by providing a detection device, the weight of the fire extinguisher can be detected by observing the position of the floating block from the fixed ring, making it very convenient to detect an invalid fire extinguisher; and because even fire extinguishers of the same model have different weights, the fixed ring and the floating block are arranged to cooperate with each other, so that each time a new fire extinguisher is placed on the mounting seat, the change in the liquid level height of the display column is equivalent to a "zeroing" process, so that the new fire extinguisher can correspond to a new liquid level height; thereafter, by observing the position between the floating block and the fixed ring, the weight reduction of the fire extinguisher can be observed, making the detection of the weight change of the fire extinguisher more accurate.

[0047] Example 3: Reference Figures 1 to 3 As shown, this embodiment is similar in structure to embodiment 2, except that a floating hole is provided through the floating block, and the upper end of the connecting rod is threadedly connected to the floating hole.

[0048] In this embodiment, the distance between the limit plate and the floating block can be adjusted by threaded connection between the connecting rod and the floating block, so that the measured stroke of the fire extinguisher can be adjusted, making it suitable for different models of fire extinguishers.

[0049] The above-described embodiments are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
