Description

Technical Field

[0001] The invention relates to the technical field of electric automatic control cabinets, in particular to an anti-leakage control cabinet for electronic detonator pressure resistance testing equipment. Background Art

[0002] In the production and testing process of electronic detonators, it is crucial to ensure their safety and reliability. As a special explosive device, electronic detonators integrate complex electronic components and detonation systems. Therefore, during the pressure test phase, the test environment must be strictly controlled to prevent any factors that may cause accidental explosions or failures. Among them, leakage prevention is one of the key links to ensure test safety.

[0003] The patent with announcement number CN221353555U discloses an electrical automatic control cabinet with leakage prevention, which connects the cable from the wire inlet to the inside of the cabinet, and then connects the cable to the inside of the air switch and the inside of the leakage protector in turn, and then passes through the inside of the wire outlet to connect to other devices. The air switch can effectively monitor the current of the line. Once it exceeds the set value, it will directly trip and cut off the circuit. The leakage protector will directly cut off the power supply when it detects leakage to prevent users from being injured. At the same time, the structure also effectively prevents the leakage from tripping, thereby improving the overall safety of the device; and ventilation holes are opened on the side panels of the cabinet, and a negative pressure fan is set on the top of the cabinet to discharge heat in time when the temperature in the cabinet is too high, thereby improving the overall stability of the device.

[0004] Although the above scheme can discharge the high-temperature air in the cabinet, in the process of discharging the high-temperature air, the negative pressure fan draws out the air on the top layer inside the cabinet. After the external air enters the cabinet from the air exchange holes on the side panel, it is sucked by the negative pressure fan and moves upward along the inner wall of the cabinet. The contact area between the air and the equipment arranged inside the cabinet is small, and the effect of removing heat from the equipment is poor. At the same time, the high-temperature air under the equipment is blocked by the equipment and cannot flow to the negative pressure suction fan efficiently. Summary of the invention

[0005] In view of the above problems, a leakage-proof control cabinet for electronic detonator pressure test equipment is provided. By arranging an exhaust and intake mechanism and a ventilation mechanism, the airflow path flows parallel to the upper and lower surfaces of the equipment, thereby increasing the contact area between the airflow and the equipment, reducing the obstruction of the equipment to the airflow, and avoiding the reduction of the airflow speed, thereby achieving rapid cooling of the air inside the control cabinet body and improving the heat dissipation efficiency.

[0011] Preferably, the opening and closing mechanism also includes an auxiliary component for maintaining the exhaust port open.

[0012] Preferably, a one-way exhaust structure for controlling the exhaust window switch is provided on the exhaust window of the U-shaped control panel. When the air storage bag inhales air, the exhaust window is in a closed state, and when the air storage bag deflates air, the exhaust window is in an open state.

[0013] Preferably, the ventilation mechanism further includes a plurality of third driving components respectively used to drive a plurality of filter components to move.

[0014] Preferably, the ventilation mechanism further comprises a second reset component disposed at the upper end of the filter component for controlling the separation of the filter component from the filter screen.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is provided with an intake and exhaust mechanism and a ventilation mechanism, and the ventilation window is kept in an open state, allowing free exchange of internal and external air, and effectively filtering impurities in the air through the configured filter screen, thereby ensuring the quality of air entering the control cabinet. When the temperature inside the control cabinet body is too high, the intake and exhaust mechanism is started, and the air pressure inside the control cabinet is reduced through the suction action of the air storage bag, prompting the ventilation window to be transformed into an air intake channel, guiding the external low-temperature air to quickly enter the control cabinet to achieve rapid cooling, and in the process of external air entering, the filter assembly on the ventilation window overlaps with the filter screen, further enhancing the filtering effect, and due to the suction effect of the air storage bag and the large-area ventilation window design, a horizontal airflow is formed inside the control cabinet body, and this airflow path flows parallel to the upper and lower surfaces of the equipment, which not only increases the contact area between the airflow and the equipment, but also reduces the obstruction of the equipment to the airflow, avoids the reduction of the airflow speed, thereby achieving rapid cooling of the air inside the control cabinet body and improving the heat dissipation efficiency.

[0017] 2. The present invention is provided with a U-shaped control panel and two first drive components, and the two first drive components simultaneously apply a force to the U-shaped control panel away from the first side panel, so that the two ends of the U-shaped control panel can move synchronously and quickly open the air storage bag, thereby quickly generating a large air suction or pressure change inside the control cabinet body, thereby promoting the rapid flow of air in the control cabinet.

[0018] 3.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figures 1 to 12 As shown: a leakage-proof control cabinet for electronic detonator pressure test equipment, comprising a control cabinet body 1, an air intake and exhaust mechanism 2 and a ventilation mechanism 3; the control cabinet body 1 comprises a first side plate 11 and a second side plate 12 symmetrical about a middle plane, a plurality of mutually parallel partitions 13 are arranged from top to bottom inside the control cabinet body 1, an exhaust port is opened in the middle of the first side plate 11, a ventilation port is opened in the middle of the second side plate 12, and the ventilation port covers a plurality of partitions 13; the air intake and exhaust mechanism 2 is arranged on the first side plate 11, and the air intake and exhaust mechanism 2 comprises an air storage bag 21 and a gas storage bag 21 connected to the exhaust port A control mechanism 22 for controlling the air storage and exhaust of the air storage bag 21; the ventilation mechanism 3 is arranged on the second side panel 12, and the ventilation mechanism 3 includes a ventilation window 31 for covering the ventilation port, and a plurality of filter screens 32 are arranged on the ventilation window 31 at equal intervals, and a filter assembly 33 is provided on the upper end of each filter screen 32, which is tightly attached to the ventilation window 31, and the filter assembly 33 can move up and down along the ventilation window 31, and the filter assembly 33 includes a mounting box 331 and a filter element 332, the opening end of the mounting box 331 is tightly attached to the ventilation window 31, and the filter element 332 is arranged in the mounting box 331.

[0034] When the control cabinet body 1 is working normally, its internal temperature is within the set range. At this time, the ventilation window 31 in the ventilation mechanism 3 is in an open state, allowing the inside of the control cabinet body 1 to freely exchange air with the outside air. The several filters 32 configured on the ventilation window 31 can effectively filter impurities in the air entering the control cabinet body 1 to ensure the air quality. Since the temperature is moderate at this time and the gas flow speed is relatively slow, the filter 32 can give full play to its filtering efficiency. When the internal temperature of the control cabinet body 1 exceeds the normal use range, it is necessary to quickly dissipate heat. At this time, the suction and exhaust mechanism 2 is started, and the control mechanism 22 drives the air storage bag 21 to perform the suction operation. The air storage bag 21 is connected to the inside of the control cabinet body 1 through the exhaust port, and the high-temperature gas is sucked into the air storage bag 21. This causes the air pressure inside the control cabinet body 1 to decrease. Due to the air pressure difference, the ventilation window 31 mainly plays the role of air intake at this time, guiding the external low-temperature air to quickly enter the control cabinet body 1 through the ventilation window 31. During the process of external air entering, the filter component 33 covers the filter net 32, and the filter element 332 can effectively filter impurities in the air to ensure that the air entering the control cabinet body 1 is clean. At this time, due to the suction effect of the air storage bag 21 and the large-area ventilation window 31, a horizontal airflow is formed inside the control cabinet body 1. The airflow flows parallel to the upper and lower surfaces of the equipment, increasing the contact area between the airflow and the equipment, while reducing the obstruction of the equipment to the airflow and avoiding the reduction of the airflow speed, thereby achieving rapid cooling of the air inside the control cabinet body 1 and improving the heat dissipation efficiency.

[0035] Reference Figure 4 and Figure 5 As shown: the control mechanism 22 includes a U-shaped control board 221 and at least two first drive components 222; an exhaust window connected to the inner cavity of the air storage bag 21 is opened in the middle of the U-shaped control board 221, and both ends of the U-shaped control board 221 are movable through the first side plate 11; the two first drive components 222 are respectively arranged at the two ends of the U-shaped control board 221, and the two ends of the first drive component 222 are respectively connected to the first side plate 11 and the U-shaped control board 221.

[0036] When the air storage bag 21 needs to perform an air suction operation, the first bar-shaped electromagnets in the two first drive components 222 are synchronously adjusted to the same polarity, causing the two first bar-shaped electromagnets in the same first drive component 222 to repel each other, so that both ends of the U-shaped control board 221 are pushed away from the first side plate 11, thereby opening the air suction channel of the air storage bag 21. At this time, the air storage bag 21 generates a strong suction force on the inside of the control cabinet body 1, and quickly sucks the high-temperature air into the air storage bag 21. When the air storage bag 21 needs to perform an exhaust operation, the two first drive components 22 2 is synchronously adjusted to opposite polarities, resulting in the mutual attraction of the two first bar-shaped electromagnets in the same first driving component 222, so that the two ends of the U-shaped control plate 221 are subjected to a pulling force close to the first side plate 11, thereby compressing the air storage bag 21 and discharging the high-temperature air inside it. Since the two first driving components 222 can quickly adjust the position of the U-shaped control plate 221, the air storage bag 21 can be quickly opened, thereby quickly generating a large air suction or pressure change inside the control cabinet body 1, thereby promoting the rapid flow of air in the control cabinet.

[0037] Reference Figure 4 and Figure 6 As shown, a plurality of guide pillars 223 are disposed on both sides of the U-shaped control plate 221 , and one end of the guide pillar 223 is movable and vertically penetrates the first side plate 11 .

[0038] When the U-shaped control plate 221 performs the control of the air extraction or exhaust of the air bag 21, the U-shaped control plate 221 is limited only by the movable connection between the two ends and the first side plate 11. However, due to the uneven distribution of the force applied to the U-shaped control plate 221 during the air extraction or exhaust process of the air bag 21, the U-shaped control plate 221 may produce unexpected swings, which may reduce the efficiency of opening or contracting the air bag 21. Therefore, a plurality of guide pillars 223 are arranged on the U-shaped control plate 221. When the U-shaped control plate 221 is driven to move by the two first driving assemblies 222, relative sliding occurs between the guide pillars 223 and the first side plate 11. The above sliding not only limits the moving direction of the U-shaped control plate 221, so that the U-shaped control plate 221 moves along the axial direction of the guide pillars 223, but also effectively maintains the parallel relationship between the middle part of the U-shaped control plate 221 and the first side plate 11 through the joint action of multiple guide pillars 223, thereby maintaining the opening or contraction efficiency of the air bag 21 unchanged.

[0039] Reference Figure 4 , Figure 5 and Figure 7 As shown, both ends of the U-shaped control plate 221 are provided with vibration-proof components 224 , and the first side plate 11 is located in the middle of the vibration-proof component 224 .

[0040] If the air bag 21 is required to generate a greater suction force on the air inside the control cabinet body 1 so that the air in the control cabinet quickly flows into the air bag 21, then the air bag 21 needs to be opened at a faster speed, and the U-shaped control plate 221 needs to move away from the first side plate 11 at a faster speed. Similarly, if the air bag 21 wants to quickly discharge the air inside itself, the U-shaped control plate 221 needs to move quickly toward the first side plate 11. When the U-shaped control plate 221 moves to the stop position, the U-shaped control plate 221 will inevitably collide with the first side plate 11, causing the speed of the U-shaped control plate 221 to return to zero, and the collision will inevitably generate vibration, so Vibration-absorbing components 224 are provided at both ends of the U-shaped control panel 221, and the vibration-absorbing components 224 include two vibration-absorbing rubber pads 2241. The first side panel 11 is located in the middle of the two vibration-absorbing rubber pads 2241. When the air bag 21 is opened and compressed, the two vibration-absorbing rubber pads 2241 contact the two ends of the first side panel 11 in turn. The vibration-absorbing rubber pads 2241 can effectively buffer the collision between the U-shaped control panel 221 and the first side panel 11, and reduce the vibration of the first side panel 11, thereby effectively reducing the collision sound when the U-shaped control panel 221 contacts the first side panel 11, and reducing the sound of the operation of the control cabinet body 1.

[0041] Reference Figure 3 , Figure 4 and Figure 8 As shown: the air intake and exhaust mechanism 2 also includes an opening and closing mechanism 23 arranged on the inner side of the first side plate 11, the opening and closing mechanism 23 includes a sealing structure 231 for controlling the exhaust port switch, the sealing structure 231 includes a sealing cover 2311, two sealing plates 2312 and a second driving component 2313, the sealing cover 2311 is arranged around the exhaust port, the two sealing plates 2312 are symmetrically arranged in the sealing cover 2311, and the sealing plates 2312 are slidably connected to the sealing cover 2311, the second driving component 2313 is arranged between the two sealing plates 2312, and is used to control the two sealing plates 2312 to approach or move away from each other, the second driving component 2313 includes two second bar electromagnets, and the two second bar electromagnets are respectively arranged on the two sealing plates 2312.

[0042] When the air bag 21 is subjected to the extrusion exhaust operation, if the exhaust port is not closed in time or completely, part of the high-temperature gas in the air bag 21 will flow back into the control cabinet body 1. Therefore, a sealing structure 231 is provided on the exhaust port of the first side panel 11. When the air bag 21 needs to inhale, the magnetism of the two second bar-shaped electromagnets is adjusted to the same polarity to generate a mutually repelling force, driving the two sealing plates 2312 away from each other, thereby opening the sealing cover 2311 and making the exhaust port open. On the contrary, when the air bag 21 needs to be exhausted, the magnetism of the two second bar-shaped electromagnets is adjusted to the opposite polarity to generate a mutually attractive force, causing the two sealing plates 2312 to approach each other and finally abut against each other, thereby closing the sealing cover 2311 and closing the exhaust port, effectively preventing the high-temperature gas from flowing back.

[0043] Reference Figure 3 , Figure 4 and Figure 8 As shown: the opening and closing mechanism 23 also includes an auxiliary component 232 for maintaining the exhaust port open, the auxiliary component 232 includes two first guide rods 2321, the two first guide rods 2321 are respectively arranged at the upper and lower ends of the sealing cover 2311, and the two first guide rods 2321 are parallel to each other, two first sliders 2322 are slidably connected to the first guide rod 2321, and the two first sliders 2322 are respectively connected to the two sealing plates 2312, a first spring 2323 is arranged in the middle of the first guide rod 2321, and the two ends of the first spring 2323 are respectively connected to the two first sliders 2322.

[0044] To ensure that the control cabinet body 1 can quickly discharge high-temperature air after the temperature rises, the exhaust port needs to remain open for a long time. However, if the two second bar electromagnets are continuously energized to control the two sealing plates 2312 to move away from each other, the energy consumption of the control cabinet will increase. Conversely, if the power supply to the two second bar electromagnets is stopped, the two sealing plates 2312 may move due to external factors, affecting the size of the exhaust port. Therefore, an auxiliary component 232 is provided. When the two second bar electromagnets are in a non-energized state, the two first springs 2323 will apply a continuous, mutual-moving force to the two sealing plates 2312 to ensure that the sealing plates 2312 are stably fixed on both sides of the sealing cover 2311. This not only avoids unnecessary movement of the sealing plates 2312 when not in use, but also ensures that when the air bag 21 is performing a vacuum operation, the exhaust port can be stabilized in the maximum open state, thereby allowing the air bag 21 to generate suction on the air within the maximum range at the moment of operation.

[0045] Reference Figure 3 , Figure 4 and Fig. 9As shown: a one-way exhaust structure 24 for controlling the exhaust window switch is arranged on the exhaust window of the U-shaped control panel 221. When the air storage bag 21 inhales, the exhaust window is in a closed state, and when the air storage bag 21 exhausts, the exhaust window is in an open state. The one-way exhaust structure 24 includes an exhaust net 241 covering the exhaust window. A partition plate 242 is arranged on one side of the exhaust net 241. The partition plate 242 is arranged parallel to the exhaust net 241. A plurality of first reset components 243 are arranged on the partition plate 242. The first reset component 243 includes a second guide rod 2431 movably penetrating the exhaust net 241 and a second spring 2432 sleeved on the second guide rod 2431. Both ends of the second spring 2432 are respectively abutted against ends of the exhaust net 241 and the second guide rod 2431.

[0046] When the control mechanism 22 does not control the air storage bag 21 to work, the second spring 2432 in the first reset assembly 243 applies a force to the second guide rod 2431 toward the inside of the control cabinet body 1, and the second guide rod 2431 drives the partition plate 242 to fit with the exhaust net 241 to close the exhaust window, so that the air storage bag 21 forms a shape with only one air inlet. When the air storage bag 21 inhales, the air in the control cabinet body 1 can be effectively inhaled into the air storage bag 21. When the control mechanism 22 controls the air storage bag 21 to exhaust, Since the air bag 21 is in a completely closed state, the internal air pressure rises and exerts pressure on the surrounding environment. This pressure is transmitted to the partition plate 242 through the exhaust net 241, causing the partition plate 242 to overcome the elastic force of the second spring 2432 and displace relative to the exhaust net 241, so that an exhaust channel is formed between the partition plate 242 and the exhaust net 241. The air in the air bag 21 can therefore be discharged from the air bag 21, thereby achieving unidirectional fluidity of the air during the intake and exhaust process of the air bag 21, and effectively controlling the flow of air.

[0047] Reference Fig.10 and Fig.11 As shown, the ventilation mechanism 3 further includes a plurality of third driving components 34 respectively used to drive a plurality of filter components 33 to move.

[0048] When the air intake and exhaust mechanism 2 is in a non-working state, the air inside the control cabinet body 1 is naturally exchanged with the outside through the ventilation window 31. In order to avoid adverse effects on air flow efficiency and heat dissipation effect, the filter assembly 33 does not overlap with the filter screen 32 at this time. However, when the air intake and exhaust mechanism 2 is in a working state, the outside air is quickly sucked into the control cabinet body 1 and is initially filtered through the filter screen 32. Due to the strong suction force, some tiny impurities may be deformed under the strong suction force and penetrate the filter screen 32 to enter the inside of the control cabinet body 1. Therefore, when the air intake and exhaust mechanism 2 is working, the third drive assembly 34 is started. The third drive assembly 34 includes two third bar-shaped electromagnets. By adjusting the two When the magnetism of the two third bar-shaped electromagnets is in the same state, a repulsive force is generated between the two third bar-shaped electromagnets, which push them away from each other and drive the filter assembly 33 to translate toward the filter screen 32 until the two completely overlap. At this time, the filter screen 32 and the filter assembly 33 are sequentially arranged on the air flow path. The former performs primary filtration and the latter performs secondary filtration, which effectively blocks impurities that may penetrate the filter screen 32 due to suction deformation, and ensures the clean air inside the control cabinet body 1, thereby realizing the dynamic coordination of the filter assembly 33 and the filter screen 32, which not only ensures the air circulation efficiency of the air intake and exhaust mechanism 2 in the non-working state, but also enhances the filtering ability of the air intake and exhaust mechanism 2 to impurities in the working state.

[0049] Reference Fig.10 and Fig.11 As shown: the ventilation mechanism 3 also includes a second reset component 35 arranged at the upper end of the filter component 33 to control the separation of the filter component 33 and the filter net 32. The second reset component 35 includes at least two reset rods 351. The two reset rods 351 are respectively arranged at the two ends of the upper end of the filter component 33, and the two ends of the reset rod 351 are respectively hinged to the ventilation window 31 and the filter component 33.

[0050] When the air intake and exhaust mechanism 2 is not in operation, in order to maintain the separation of the filter assembly 33 and the filter screen 32, it is necessary to continuously power the two third bar-shaped electromagnets in the third drive assembly 34 so that the two third bar-shaped electromagnets maintain opposite magnetic properties to attract each other, thereby fixing the position of the filter assembly 33. However, this will increase the energy consumption of the control cabinet body 1. In order to reduce energy consumption and prevent the filter assembly 33 from sliding down due to gravity after power failure, a second reset assembly 35 is designed above the filter assembly 33 to provide a reset function. When the third drive assembly 34 is activated, the filter assembly 33 is driven to move toward the filter screen 32 and to be in contact with the filter screen 32. When the filter screen 32 overlaps, the two reset rods 351 are stretched. Once the power supply to the third drive component 34 is stopped, the two reset rods 351 use their elastic potential energy to reset, and pull the filter component 33 upward through the hinge point to separate the filter component 33 from the filter screen 32, and maintain this separation state until the next activation of the third drive component 34. This achieves the goal of maintaining the separation of the filter component 33 and the filter screen 32 when the air intake and exhaust mechanism 2 is not in operation, without continuously powering the third drive component 34, thereby reducing the overall energy consumption of the control cabinet body 1.

[0051] Reference Fig.10 and Fig.12 As shown: the ventilation mechanism 3 also includes a plurality of connecting plates 36 and two guide columns 37; the plurality of connecting plates 36 are respectively arranged between two adjacent filter components 33, and the two ends of the connecting plates 36 are respectively connected to the two filter components 33; the two guide columns 37 are arranged in parallel on both sides of the plurality of filter components 33, and are slidably connected to the filter components 33.

[0052] A third drive assembly 34 is provided on one side of each filter assembly 33. When the air intake and exhaust mechanism 2 is working, it is necessary to provide electrical energy to all third drive assemblies 34, resulting in increased energy consumption. Therefore, a plurality of connecting plates 36 and two guide columns 37 are provided. The plurality of connecting plates 36 connect all the filter assemblies 33 in sequence from top to bottom, and the two guide columns 37 limit the filter assembly 33 to fit with the ventilation window 31. When the three drive assemblies push the filter assembly 33 toward the filter net 32, the filter assembly 33 and the filter assembly 33 transfer kinetic energy through the connecting plate 36, so that all the filter assemblies 33 move synchronously. Moreover, with the cooperation of the two guide columns 37, the filter assembly 33 and the filter net 32 ​​can remain in close contact after they overlap, so as to prevent air from flowing into the control cabinet body 1 through the gap between the two. By introducing a plurality of connecting plates 36 and two guide columns 37, energy consumption is reduced, and synchronous and stable movement of multiple filter assemblies 33 is achieved.

[0053] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
