[0014] Beneficial effects

[0015] The present invention provides a modular secondary water supply device. Compared with the prior art, it has the following advantages:

[0016] (1) The combined modular secondary water supply equipment adds an alarm structure under the mechanical lock of the flip door. It is manually unlocked before opening the door. No alarm will be sounded when the mechanical lock is opened again. If an unrelated person directly and illegally opens the mechanical lock, the alarm structure will trigger an on-site whistle alarm and send an alarm signal to the control room to remind the staff to achieve a warning effect. It can also trigger the electric push rod to push the card block to lock the lock sleeve to prevent the flip door from being opened, thereby improving the safety and anti-theft effect. The alarm structure can also be automatically reset when the door is closed, which is easy to use.

[0017] (2) The combined modular secondary water supply equipment can provide better sunshade and rain protection by setting the flip door in an upward flip form and arranging side panels composed of waterproof cloth and frame on both sides, thereby improving the comfort of maintenance in hot weather and rainy days, and also avoiding the problem of rainwater drifting into the water supply station and causing circuit failure during maintenance in rainy days. After the flip door is unfolded, the front and rear clamping shafts can be used to clamp the elastic buckle to achieve fixation, which is safe and convenient to use.

[0018] (3) The combined modular secondary water supply equipment can receive the water leaking from the water tank by setting a water receiving chassis at the bottom of the water tank, and gather it in the middle to be sensed by the water drop sensor, thereby realizing an alarm, which is convenient for the staff to repair in time. The water tank is set in a closed space, and the exhaust nozzle is used in conjunction with the exhaust assembly to circulate the air in the space where the water tank is located, and dehumidify it during the circulation process, thereby keeping the air in the space dry, and avoiding the problem of moisture in the air condensing on the surface of the water tank and the condensed water flowing down to cause false detection.

[0019] (4) The combined modular secondary water supply equipment can install water pumps and pipelines in a modular manner and reserve installation positions for connecting water pumps. It can install an appropriate number of water pumps as needed, and can also increase water pumps when necessary to ensure sufficient water supply and facilitate maintenance and replacement.

[0020] (5) This modular secondary water supply equipment changes the horizontal layout of the traditional secondary water supply equipment into a vertical stacking layout, which saves space. Telescopic ladders are set on both sides of the water supply station to facilitate workers to climb up and down. The telescopic ladders can be pulled open and easily extended to support the ground. The bending plates on both sides can be used in conjunction with the oblique card blocks to achieve quick locking. The telescopic ladder can be easily retracted by pressing the bending plates, which makes operation more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The present invention provides five technical solutions:

[0034] Figure 1-5The first embodiment is shown: a combined modular secondary water supply device, including a water tank 1, a water pump 2 and a pipeline 3 connecting the two. A liquid level sensor is provided in the water tank 1 to detect the liquid level. The water tank 1, the water pump 2 and the pipeline 3 are modularly assembled and installed. The device also includes an external water supply station 4. The water supply station 4 is provided with a roof 21 on top, and a photovoltaic panel 13 is fixedly connected to the top of the roof 21. The water tank 1 is installed at the bottom of the inner cavity of the water supply station 4. The middle layer inside the water supply station 4 is fixedly supported by a cross steel frame 22 and a partition 24 is installed. The water pump 2 is installed on the top of the partition 24. The partition 24 is also equipped with an electric control box 25 for controlling various electrical appliances and a tool cabinet 10 for placing tools. The tool cabinet 10 contains maintenance tools, a fire extinguisher and an exhaust assembly 9.

[0035] On both sides of the water supply station 4 and at the top of the partition 24, there are rotatably connected a reversible door 11 that can be turned upwards. The bottom of the inner side of the reversible door 11 is fixedly connected to a mechanical lock 12. On both sides of the partition 24 and directly below the mechanical lock 12, there are fixedly connected an alarm structure 6.

[0036] The alarm structure 6 includes a fixed base 61 fixedly connected to the side of the partition 24, and an alarm 62 is provided on one side of the fixed base 61. The alarm 62 sounds an alarm on site and by remote wireless transmission. The interior of the fixed base 61 is rotatably connected to a rotating block 64 via a rotating shaft 63. The top of the fixed base 61 is provided with a lock slot for inserting the lock tongue of the mechanical lock 12. The sides of the rotating block 64 and the sides of the lock tongue are fixedly connected to a triangular block 65 and two groups of parallel and non-contact first metal springs 66. The interior of the fixed base 61 and the side of the triangular block 65 away from the lock tongue are fixed. A small spring piece 67 is connected, and a second metal spring piece 68 that can contact the two first metal spring pieces 66 at the same time is fixedly connected inside the fixed seat 61 and located on the side of the first metal spring piece 66 away from the lock tongue. The two first metal spring pieces 66 are electrically connected to the alarm 62 through wires. The rotating shaft 63 is elastically rotatably connected to the inner hole of the fixed seat 61 through a torsion spring 69, and the end of the rotating shaft 63 located outside the fixed seat 61 is fixedly connected to the bolt head 610. Multiple fake bolt heads are welded to the side of the water supply station 4 in parallel with the bolt head 610, which has the effect of confusing and concealing the real bolt head 610.

[0037] A lock sleeve 14 is fixedly connected to the bottom of the inner side of the flip door 11 and outside the mechanical lock 12. An electric push rod 611 is provided inside the fixed seat 61 and at the other end of the rotating shaft 63. The top of the electric push rod 611 is fixedly connected to a block 612 that can be inserted into the lock sleeve 14 to lock it. The alarm 62 activates the electric push rod 611 at the same time as the alarm sounds.

[0038] In the initial state, the lock tongue of the mechanical lock 12 presses down the triangular block 65, so that the first metal spring piece 66 is in a state of being separated from the second metal spring piece 68. When opening the door, the bolt head 610 is first rotated to rotate the rotating shaft 63 to drive the rotating block 64 to rotate. The triangular block 65 squeezes the small spring piece 67 and rotates to its other side. The small spring piece 67 is used to clamp the triangular block 65 to prevent rebound. At this time, the first metal spring piece 66 squeezes the lock tongue of the mechanical lock 12, and then the mechanical lock 12 can be opened, and the flip door 11 can be flipped up until the card shafts 17 on the front and rear sides are stuck in the elastic buckle 18. When locking the door, the lock tongue bounces into the fixed seat 61, which can hit the first metal spring piece 66 to push the rotating block 64 to rotate, thereby causing the triangular block 65 to overcome the small spring piece 67 and return to the initial state.

[0039] If the lock is unlocked directly without first rotating the bolt head 610, the lock tongue will slide up and no longer restrict the triangular block 65. Under the action of the torsion spring 69, the rotating block 64 rotates, causing the two first metal springs 66 to contact the second metal spring 68, thereby making the two first metal springs 66 conduct the circuit, and the alarm 62 is energized to sound the horn and alarm box remote wireless alarm. At the same time, the electric push rod 611 is quickly activated to push the locking block 612 upward, causing it to be inserted into the lock sleeve 14, thereby locking the flip door 11.

[0040] By adding an alarm structure 6 under the mechanical lock 12 of the flip door 11, it is manually unlocked before opening the door, and no alarm will be sounded when the mechanical lock 12 is opened afterwards. If an unrelated person directly and illegally opens the mechanical lock 12, the alarm structure 6 will trigger an on-site whistle alarm and send an alarm signal to the control room to remind the staff to achieve a warning effect. It can also trigger the electric push rod 611 to push the card block 612 to lock the lock sleeve 14 to prevent the flip door 11 from being opened, thereby improving the security and anti-theft effect. The alarm structure 6 can also be automatically reset when closing the door, which is convenient to use.

[0041] Figure 2 and 9 A second embodiment is shown, which mainly differs from the first embodiment in that: a frame 15 is fixedly connected to the front and rear sides of the inner side of the flip door 11, and a waterproof cloth 16 is fixedly connected to the inner side of the frame 15, and a card shaft 17 is fixedly connected to the outer side of the frame 15 and a corner away from the flip door 11, and an elastic clip 18 is fixedly connected to the front and rear sides of the water supply station 4. After the flip door 11 is flipped up, the card shaft 17 can be stuck into the elastic clip 18.

[0042] By setting the flip door 11 in an upward flip-up form and arranging side panels consisting of waterproof cloth 16 and frame 15 on both sides, it can achieve better sunshade and rain protection effects, improve the comfort of maintenance in hot weather and rainy days, and avoid the problem of rainwater drifting into the water supply station 4 and causing circuit failure during maintenance in rainy days. After the flip door 11 is unfolded, the front and rear clamping shafts 17 can be used to clamp the elastic buckle 18 to achieve fixation, which is safe and convenient to use.

[0043] Figure 1-2 and 6-7 show a third embodiment, which mainly differs from the second embodiment in that: the lower half of the water supply station 4 and the water tank 1 are sealed and fixedly connected with an inspection plate 19, and the inner side of the inspection plate 19 is fixedly connected with an insulation lining 20, and a water leakage warning component 5 is provided at the bottom of the water supply station 4. The water leakage warning component 5 includes a base 51 and a water receiving chassis 52 fixedly connected to its top, the water tank 1 is placed on the top of the water receiving chassis 52, and a leakage hole 53 is provided at the bottom of the water receiving chassis 52 and located on the outside of the water tank 1, and an inclined groove 54 connected to the leakage hole 53 is provided on the top of the base 51, and a water collecting trough 55 is provided in the center of the top of the base 51, the lowest end of the inclined groove 54 is connected to the side of the water collecting trough 55, and a water drop sensor 56 is fixedly connected to the inside of the water collecting trough 55, and the inside of the base 51 and the bottom of the side of the water collecting trough 55 are connected to a drainage pipe 57 that penetrates to the outside, and the outer end of the drainage pipe 57 is threadedly connected to an end cover.

[0044] When the water tank 1 leaks, the water flows into the water receiving chassis 52, then flows into the chute 54 through the leakage hole 53, and then gathers in the intermediate water collection tank 55 and is sensed by the water drop sensor 56, which then issues a remote alarm to remind the staff to repair it in time. During maintenance, it is necessary to open the end cover of the drain pipe 57 to drain the water, and then remove the inspection panels 19 around it for maintenance.

[0045] An exhaust nozzle 7 is fixedly connected to the center of the partition 24, and the bottom end of the exhaust nozzle 7 is inserted into the inside of the cross steel frame 22. The top of the exhaust nozzle 7 can be inserted with an exhaust assembly 9 to circulate air at the bottom of the partition 24. A partition plate 221 that separates the exhaust ends of the exhaust nozzle 7 is fixedly connected to the middle of the bottom of the cross steel frame 22, and vents 222 are provided at the bottom of the four ends of the cross steel frame 22.

[0046] The exhaust assembly 9 includes a drying cylinder 91 with two independent cavities on the left and right sides, and screw covers 92 are threadedly connected at both ends of the drying cylinder 91. One side of the screw cover 92 is fixedly connected to a mesh cylinder 93 filled with activated carbon particles inserted into the independent cavity by screws. A fan 94 is fixedly connected to the middle of the top of the drying cylinder 91, and air guide covers 95 are fixedly connected to both ends of the fan 94 and both sides of the top of the drying cylinder 91. A handle is fixedly connected between the tops of the two air guide covers 95. Ventilation holes are provided on the top of the drying cylinder 91 and inside the two air guide covers 95. The bottom of the drying cylinder 91 is connected to two plugs 96 that are plugged into the top of the exhaust nozzle 7.

[0047] The exhaust nozzle 7 includes two groups of symmetrically arranged sleeves 71, and the diameter of the lower half of the sleeve 71 is larger than that of the upper half. A limiting tube 72 with a side opening is slidingly provided inside the upper half of the sleeve 71, and the bottom end of the limiting tube 72 is fixedly connected to a piston 73 that can block the upper half of the sleeve 71. The bottom of the piston 73 is in contact with the top of the inner surface of the sleeve 71 through a spring 74. A through hole is provided at the bottom of the sleeve 71, and a sealing rubber ring 75 is embedded and fixedly connected to the interior of the upper half of the sleeve 71.

[0048] After the maintenance of the water tank 1 is completed, the outer surface and the insulation lining 20 are wiped dry, and then the inspection plate 19 is installed back. The exhaust assembly 9 is removed and the nozzle 96 is inserted into the exhaust nozzle 7, so that the nozzle 96 presses down the limit tube 72, and then the piston 73 opens the sleeve 71, and the fan 94 is started to extract the air from half of the cavity of the cross steel frame 22 through the sleeve 71 on one side of the exhaust nozzle 7, and then the air in the space below the partition 24 is extracted through the bottom vent 222. The air first passes through the activated carbon in the mesh tube 93 on one side for drying, and then the air is discharged to the mesh tube 93 on the other side for secondary drying, and then discharged to the other half of the cavity of the cross steel frame 22, and discharged from the bottom vent 222 to achieve circulation.

[0049] By setting a water receiving base plate 52 at the bottom of the water tank 1, the water leaking from the water tank 1 can be received and gathered in the middle to be sensed by the water drop sensor 56, thereby generating an alarm, which is convenient for the staff to repair in time. The water tank 1 is set in a confined space, and the exhaust nozzle 7 is used in conjunction with the exhaust component 9 to circulate the air in the space where the water tank 1 is located, and dehumidify it during the circulation process, thereby keeping the air in the space dry, and avoiding the problem of moisture in the air condensing on the surface of the water tank 1 and the condensed water flowing down to cause false detection.

[0050] Figure 1-2 and 8 show a fourth embodiment, the main difference from the third embodiment is that: a tap water filling pipe 23 that passes through the outside of the inspection panel 19 is fixedly connected to the top of the front of the water tank 1, the pipeline 3 includes a sliding pipe 31 that passes through the rear wall of the upper half of the water supply station 4, and a converging pipe 32 is fixedly connected between the front end of the sliding pipe 31 and the front wall of the water supply station 4 by a flange and bolts. The front end of the converging pipe 32 is closed, and a flow meter is installed on the rear end surface. A plurality of water injection branches 33 are fixedly connected to the side of the converging pipe 32, and a plurality of water extraction pipes 34 are inserted in the partition 24 and located in front of the water injection branch 33, and the bottom end of the water extraction pipe 34 extends to the bottom of the inner cavity of the water tank 1. The input and output ends of the water pump 2 are connected to the water extraction pipe 34 and the water injection branch 33 respectively through pipes. A plurality of water pump installation positions are provided on the top of the partition 24 corresponding to the positions of the water injection branch 33 and the water extraction pipe 34, and the ends of the water injection branch 33 and the water extraction pipe 34 that are not connected to the water pump 2 are fixedly connected with a sealing cover 35.

[0051] By modularly installing the water pump 2 and the pipeline 3 and reserving an installation position for connecting the water pump 2, an appropriate number of water pumps 2 can be installed as needed, and water pumps 2 can be added when necessary to ensure sufficient water supply and facilitate maintenance and replacement.

[0052] Figure 1-2 10 shows a fifth embodiment, which is different from the fourth embodiment in that: the middle of the left and right sides of the water supply station 4 are hinged with a telescopic ladder 8, and the telescopic ladder 8 includes two sets of front and rear sleeves 81 fixedly connected to the water supply station 4, and a plurality of cross bars 88 are fixedly connected equidistantly between the front and rear sets of sleeves 81. The inner sliding connection of the sleeve 81 is connected to the extended leg 82, and the bottom of the extended leg 82 is fixedly connected to the anti-sliding block 83. The bottom surface of the anti-sliding block 83 is an arc surface, and a plurality of ridges are provided to increase friction. Friction, the outer side of the sleeve 81 is rotatably connected to a bent plate 84, and the bent part of the bent plate 84 is rotatably connected to the surface of the sleeve 81, and the bottom of the bent plate 84 close to the sleeve 81 is fixedly connected to an oblique clamping block 86 with an embedded magnet 85. A through hole is provided on the side of the sleeve 81 for the oblique clamping block 86 to pass through, and a positioning groove 87 is provided on the side of the extended leg 82 to engage with the oblique clamping block 86. The oblique clamping block 86 and the bottom surface of the positioning groove 87 are tilted, and can be locked with each other when abutting against each other to prevent the oblique clamping block 86 from deflecting outward.

[0053] When climbing, pull out the telescopic ladder 8 on the required side, and then lengthen the extended leg 82 until the oblique clamping block 86 is stuck in the positioning groove 87 under the suction force of the magnet 85 on the extended leg 82, so that the extended leg 82 can be positioned, and then lower the extended leg 82 to support the ground, and the oblique clamping block 86 is stuck in the positioning groove 87 to prevent the extended leg 82 from being retracted; when it is necessary to retract, first pull down the extended leg 82, and then press the upper part of the bending plate 84 to disengage the oblique clamping block 86 from the positioning groove 87, and then push the extended leg 82 up, and finally place the telescopic ladder 8 against the side of the water supply station 4.

[0054] By changing the traditional horizontal distribution layout of secondary water supply equipment to a vertical stacking type, space is saved, and telescopic ladders 8 are set on both sides of the water supply station 4 to facilitate workers to climb up and down, and the telescopic ladders 8 can be pulled open and easily extended to support the ground, and the bending plates 84 on both sides can be used in conjunction with the oblique card blocks 86 to achieve quick locking, and the telescopic ladder 8 can be easily retracted by pressing the bending plates 84, which is more convenient to operate.
