Description

Technical Field

[0001] The utility model belongs to the technical field of lighting, and in particular relates to a power distribution lighting box group used in a tent hospital. Background Art

[0002] With the rapid development of emergency medicine, a large number of medical rescue teams have been formed. When performing rescue missions, medical rescue teams often use tents as temporary wards and dormitories.

[0003] At present, there is no power distribution lighting system matching tents on the market. The power distribution of tents usually adopts a combination of cable reel and movable socket. The cable reel is used to introduce AC power into the tent, and then the movable socket is used to connect the cable reel and the electrical equipment. Because the tent tarpaulin is soft, the movable socket cannot be fixed on the tarpaulin and is usually placed on the ground cloth of the tent. The lighting in the tent usually adopts AC 220V LED energy-saving lamps, which are tied to the top of the tent with ropes. Because it is difficult to install switches in tents, LED energy-saving lamps are usually not equipped with switches. The switch of the lamp is directly controlled by a plug: insert the plug to turn on the power to light the energy-saving lamp, and unplug the plug to turn off the LED energy-saving lamp.

[0004] The above power distribution method has the following disadvantages:

[0005] 1. The cable has the potential safety hazard of leakage and short circuit

[0006] The cable reel and the movable socket are laid directly on the ground, which may cause the cable insulation layer to be damaged by people stepping on it or vehicles running over it. When it rains, the tent will be flooded or people will bring water stains into it. The cables and movable sockets placed on the ground will be soaked in water, which may cause short circuits and electric shocks.

[0007] 2. The lighting circuit uses strong electricity, which poses a risk of electric shock

[0008] The lighting circuit is powered by AC 220V, and the cables are laid directly in the tent, which poses a risk of electric shock. A power supply with a voltage below DC 32V (safe voltage) can be used to power the lighting to reduce the risk of electric shock.

[0009] 3. There is a risk of being struck by lightning during thunderstorms

[0010] During lightning weather, the cable reel is directly connected to the power grid / generator. When the power supply circuit is struck by lightning, surge current is introduced into the room through the cable reel, and people and electrical equipment in the room are at risk of being struck by lightning.

[0011] 4. Folding lighting fixtures do not have three-proof functions

[0012] In order to adapt to the outdoor working environment, foldable lighting fixtures are required to have waterproof, dustproof and explosion-proof functions. Ordinary LED energy-saving lamps do not have the above functions and are prone to damage. Utility Model Content

[0013] In view of this, the utility model aims at the deficiencies of the prior art and provides a power distribution lighting box group for a tent hospital, which has the advantages of modularity, protection against electric shock, protection against lightning strikes, multi-function and lightness.

[0014] The utility model solves the above-mentioned problems through the following technical means: a power distribution lighting box group for a tent hospital, comprising a box body, a safety power protector and a lamp, at least one side of the box body is hingedly provided with a desktop panel, and a side of the desktop panel away from the box body is hingedly provided with table legs; the safety power protector is arranged in the box body, and a slot for fixing the lamp is arranged on the box body.

[0015] Furthermore, the safety electricity protector includes a control panel, a power supply interface and a power supply interface.

[0016] Furthermore, a storage cabinet is arranged at the upper part of the box body, and the safety power protector is arranged at the lower part of the box body.

[0017] Furthermore, the bottom of the box is hingedly provided with box legs.

[0018] Furthermore, the lamp comprises a lamp pole and a lamp body, and the lamp body is fixedly connected to the slot via the lamp pole.

[0019] Furthermore, the lamp body includes a lamp holder and an illuminating part hinged to the lamp holder, and the lamp holder is fixedly connected to the slot via a lamp rod.

[0020] Furthermore, a cable tie threading seat is provided on the lamp body.

[0021] Furthermore, a lamp pole plug is hinged at the head end of the lamp pole, and the lamp pole plug is plugged and fixed to the lamp holder.

[0022] Furthermore, a lamp pole fixing sleeve is provided on the box body.

[0023] Furthermore, it also includes a lamp pole bracket, which includes a sleeve fixedly connected to the lamp pole, a positioning ring connected to the outside of the sleeve, and a plurality of legs arranged at intervals along the circumference and hinged to the positioning ring, each leg is connected to the bottom end of the sleeve through a connecting rod, and the two ends of the connecting rod are respectively hinged to the bottom end of the sleeve and the corresponding leg; the positioning ring and the sleeve are slidingly locked by a locking piece.

[0024] Beneficial effects of the utility model:

[0025] 1. Modular design: One box set contains all the equipment required for power distribution and lighting in the tent, and it can be used after opening.

[0026] 2. Anti-electric shock and lightning protection: On the one hand, the safety power protector has the function of an isolation transformer to isolate the AC 220V grid from the power supply in the tent. When the cable insulation layer is damaged and personnel accidentally touch the live wire, there will be no electric shock accident. When the cable is soaked in water, personnel touch the exposed live wire and there will be no electric shock accident. In the case of a large number of personnel and complex personnel in a field tent hospital, simple power supply equipment, and power supply facilities that are prone to damage, it can effectively provide safe power protection for personnel and equipment; on the other hand, the safety power protector also combines the function of a surge protector, which can effectively prevent the high-voltage electric field of lightning from being transmitted to the inside of the tent through the power supply circuit, and can effectively protect the safety of personnel and equipment in the tent.

[0027] 3. Multifunctional and lightweight design: The box set is used as a packing box when folded, and forms a folding table when unfolded. At the same time, the box set can be used as a power supply platform in the tent. The box set is made of lightweight materials, and the lighting lamp adopts an aluminum alloy shell and a folding design. The structure is strong and the storage size is small. The folding lighting lamp has three working modes: table lamp, floor lamp, and pendant lamp, which can adapt to various working scenes. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0052] like Figure 1 to Figure 2 As shown, this embodiment discloses a power distribution lighting box set for a tent hospital, including a box body 1, a safety power protector 3 and a lamp. At least one side of the box body is hinged with a desktop panel 6, and the side of the desktop panel away from the box body is hinged with a table leg 5; in this embodiment, both sides of the box body are hinged with a desktop panel. The bottom four corners of the box body are hinged with box legs 2, and the box legs can be rotated relative to the hinge point to achieve folding or unfolding. The box body is made of aluminum-magnesium alloy, and has the characteristics of high structural strength and light weight.

[0053] like Figure 3 and Figure 4 As shown in the figure, the desktop panel is in the retracted state. Figure 5As shown, the table legs are folded and stored at the bottom of the table top. When the table top is retracted, the table top is folded and stored on both sides of the box body and fixed by four anchor screws.

[0054] When the desktop panel is expanded, Figure 6 As shown in the figure, the table legs are opened, and the table legs can be designed as telescopic table legs so that the length can be adjusted to adapt to the height of the desktop. The specific process of unfolding the desktop is: first open and fix the four box legs at the bottom of the box, then open the desktop on both sides of the box, unfold the table legs, adjust the length of the table legs to adapt to the height of the desktop and lock the table legs, so that a folding table is obtained.

[0055] like Figure 7 and Figure 8 As shown, a storage cabinet 4 is provided on the upper part of the box body, wherein Figure 7 The locker door is closed. Figure 8 The locker door is removed. The locker is used to store lamps, lamp pole brackets, input cables, output cables, etc. The safety power protector is arranged at the lower part of the box body, separated from the locker by a partition, and is an independent whole.

[0056] like Figures 9 to 11 As shown, the safety power protector includes a control panel 301, a power supply interface 303 and a power supply interface 302. Its specific structure is as follows:

[0057] Control panel: There is a voltmeter, input indicator light (IN) and output indicator light (OUT). The voltmeter displays the input voltage. The input indicator light is on when the input voltage is connected to the safety power protector. The output indicator light is on when the safety power protector generates output voltage.

[0058] Power supply interface: consists of a surge protection switch, a power input interface, and two power output interfaces.

[0059] Power interface: It consists of two five-hole sockets and an air outlet. A fan is installed at the air outlet. Air is sucked in from the air inlet on the control panel side, passes through the isolation transformer, and is discharged from the air outlet by the fan. The two five-hole sockets take the secondary voltage of the isolation transformer.

[0060] The safety power protector integrates the function of isolation transformer. The working principle of isolation transformer is the same as that of ordinary transformer, which is electromagnetic induction principle. However, the turns ratio of primary and secondary coils of isolation transformer is 1:1, the primary input voltage is 220V, and the secondary output voltage is also 220V. Isolation transformer plays the role of protection, lightning protection and filtering.

[0061] The principle of electric shock protection of isolation transformer: The AC power supply we use has one wire connected to the earth, and there is a 220V potential difference between the other wire and the earth. When a person touches the live wire (L), the 220V voltage will be transmitted to the earth through the human body, which will cause electric shock. However, the secondary of the isolation transformer is not connected to the earth, and the voltage is suspended to the earth. There is no potential difference between any two of its wires and the earth. People will not get electric shock when they touch any wire, which is safer.

[0062] There are many secondary harmonics in the generator-powered circuit, which will cause serious interference to medical precision equipment and reduce the sensitivity and accuracy of the equipment. The iron core of the isolation transformer has the characteristics of large high-frequency loss, which can suppress the high-frequency noise from entering the secondary circuit and protect the medical precision equipment.

[0063] In specific applications, take out the connection cable from the locker, connect one end of the input cable to the power supply circuit or generator, and the other end to the power input interface of the power supply interface. After the connection is completed, observe the voltage meter and indicator light on the control panel. If the input voltage is normal (about 220V), the input and output indicators are on, indicating that the power supply has been output normally, and the power can be obtained from the two power output interfaces of the power supply interface or the 5-hole socket of the power port (power the lamp through the power output interface or the 5-hole socket).

[0064] like Figure 12 to Figure 14 As shown, the lamp comprises a lamp pole 7 and a lamp body 8, wherein the lamp body comprises a lamp holder 801 and an illumination part 802 hinged to the lamp holder, and the illumination part can be unfolded or folded relative to the lamp holder; Fig.12 The lighting unit is in the expanded state. Fig.13 The lighting unit is folded.

[0065] The box body is provided with a slot 9 for fixing the lamp, and the lamp holder is fixedly connected to the slot through the lamp pole. Specifically, the lamp holder is provided with a lamp pole plug connector 804, such as Fig.15 As shown, the head end of the lamp pole is hinged with a lamp pole plug 701, and the lamp pole plug is plugged and fixed with the lamp pole plug plug-in portion. Fig.14 As shown, a battery compartment 805 can be provided on the lamp holder, and the lamp pole plug connector can be integrated on the battery compartment cover.

[0066] like Fig.16 As shown, a tie threading seat 803 is provided on the lamp body, and a tie can be passed through the tie threading seat to fix the lamp body on the air column at the top of the tent, thereby forming a ceiling lamp.

[0067] It is understandable that if Fig.17As shown, when the lamp is fixed on the box to form a table lamp state, a lamp pole fixing sleeve 10 can be provided on the box to improve the reliability of the lamp pole fixing.

[0068] As a further improvement to the above technical solution, Figures 18 to 20 As shown, it also includes a lamp pole bracket, the lamp pole bracket 11 includes a sleeve 1101 fixedly connected to the lamp pole, a positioning ring 1102 sleeved on the outside of the sleeve, and a plurality of legs 1103 arranged at intervals along the circumference and hinged to the positioning ring, each leg is connected to the bottom end of the sleeve by a connecting rod 1104, and the two ends of the connecting rod are respectively hinged to the bottom end of the sleeve and the corresponding leg; the positioning ring and the sleeve are slidingly locked by a locking piece, and the locking piece can be a locking screw. The positioning ring is slid relative to the sleeve to realize the expansion or contraction of the legs. In specific applications, such as Figure 21 to Figure 22 As shown, the lamp pole 7 is connected with the lamp pole bracket 11 to form a floor lamp stand, and after the lamp body 8 is inserted, a floor lamp is formed. The floor lamp can be placed at a location in the tent where lighting is required, and can also provide outdoor lighting.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
