Technical Field

[0001] This utility model relates to the field of variable frequency water supply equipment technology, and in particular to a box-type variable frequency water supply equipment. Background Technology

[0002] Variable frequency water supply equipment is an intelligent water supply system designed to efficiently and stably meet water supply needs in different scenarios. Variable frequency water supply equipment uses a frequency converter to adjust the speed of the water pump motor and automatically adjusts the speed and number of pumps in operation based on the pipeline pressure signal fed back by the pressure sensor, thereby achieving the purpose of constant pressure water supply or variable pressure water supply.

[0003] In the prior art, such as the Chinese patent CN221321140U "A box-type full frequency conversion constant pressure water supply device", this utility model discloses a box-type full frequency conversion constant pressure water supply device. This utility model sets a float plate structure inside the water storage tank. When it is necessary to inject new water into the water tank, the float plate separates the new water from the old water, which facilitates the replacement and discharge of the old water. During the water injection process, the water is filtered by the filter screen set on the top of the water tank.

[0004] Existing water supply equipment uses a float plate to separate new water from old water during water replacement, allowing the old water to drain and the new water to be injected into the tank. However, this method cannot meet normal water supply needs during water replacement. Furthermore, the float plate occupies internal space in the tank, reducing the water storage capacity. Additionally, the seal between the float plate and the tank is not very good, allowing old water to easily mix into the new water and contaminate it. Moreover, the filter screen on top of the tank is prone to clogging after prolonged use, making it inconvenient to replace and clean the filter screen. Utility Model Content

[0005] To overcome the problems of not being able to meet normal water supply needs during water replacement, the low sealing between the float plate and the water tank, the old water easily mixing into the new water through gaps and causing pollution, and the filter screen on the top of the water tank easily becoming clogged after long-term use, making it inconvenient to replace and clean the filter screen.

[0008] Preferably, a water inlet base is fixedly installed on the bottom of the inner wall of the water storage tank, and a drain pipe is symmetrically and continuously connected to the outer side of the water storage tank, with a drain valve sealed inside the drain pipe.

[0009] Preferably, a wave-damping frame is symmetrically installed on the inner wall of the water storage tank away from the drain pipe. The wave-damping frame is located on both sides of the partition plate. A float level gauge is fixedly installed on the top surface of the water storage tank near the partition plate. The float level gauge is located inside the wave-damping frame.

[0010] Preferably, the water storage tank is symmetrically connected to the extraction pipe on the side away from the drain pipe, a water pump is symmetrically installed on the top surface of the supporting base plate, the end of the extraction pipe is sealed to the input end of the water pump, the output end of the water pump is sealed to the outlet pipe, a check valve is sealed inside the outlet pipe, and a water delivery pipe is connected through the end of the outlet pipe.

[0011] Preferably, a support frame is fixedly installed on the side of the water storage tank near the water pump, and an inlet pipe is welded to the outside of the support frame.

[0014] 1. When it is necessary to change the water in the water storage tank for maintenance, open the drain pipe through the drain valve and use the water inlet base at the bottom to guide the old water, so that the old water can be discharged out of the device through the drain pipe. Disconnect one end of the rotating joint from the connecting pipe, and rotate the other end of the connecting pipe around the three-hole joint with the rotating head to flip the connecting pipe upward. Then rotate the sealing cover off the inspection port to facilitate maintenance and repair of the inside of the water storage tank through the inspection port.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides an embodiment: a box-type variable frequency water supply device, including a supporting base plate 1 and a water storage tank 201. The water storage tank 201 is disposed on the top surface of the supporting base plate 1. The top surface of the water storage tank 201 is symmetrically provided with an inspection port 204. The outer side of the inspection port 204 is connected to a sealing cover 501 by a threaded seal. The inside of the sealing cover 501 is rotatably connected to a rotating joint 502. The bottom surface of the sealing cover 501 is connected to a water outlet mesh frame 503 by a thread. The inner wall of the water outlet mesh frame 503 is engaged with an activated carbon filter element 504.

[0024] The top surface of the water storage tank 201 is symmetrically and evenly equipped with fixing bolts 202, and the water storage tank 201 is threadedly connected and fixed to the supporting base plate 1 by the fixing bolts 202. A partition plate 203 is fixedly installed in the center of the inner wall of the water storage tank 201. The fixing bolts 202 can stably install and fix the water storage tank 201 to the supporting base plate 1 to prevent the water storage tank 201 from shaking during use. The partition plate 203 can divide the water storage tank 201 into two parts, which can store and discharge water in the water storage tank 201 simultaneously and without interference.

[0025] A water inlet base 205 is fixedly installed on the bottom of the inner wall of the water storage tank 201. A drain pipe 206 is symmetrically connected to the outer side of the water storage tank 201. A drain valve 207 is sealed inside the drain pipe 206. When discharging water, the drain pipe 206 is opened through the drain valve 207, and the old water is guided by the water inlet base 205 at the bottom, so that the wastewater can be discharged out of the device through the drain pipe 206.

[0026] A wave-damping frame 208 is symmetrically installed on the inner wall of the water storage tank 201 on the side away from the drain pipe 206. The wave-damping frame 208 is set on both sides of the partition plate 203. A float level gauge 209 is fixedly installed on the top surface of the water storage tank 201 near the partition plate 203. The float level gauge 209 is set inside the wave-damping frame 208. When filling with water, the float level gauge 209 is used to monitor the water level inside the water storage tank 201 in real time. The wave-damping frame 208 can reduce the fluctuation of the water surface during the filling process and prevent the fluctuation of the water surface from affecting the accuracy of the float level gauge 209.

[0027] A symmetrical extraction pipe 301 is symmetrically connected to the side of the water storage tank 201 away from the drain pipe 206. A water pump 302 is symmetrically installed on the top surface of the supporting base plate 1. The end of the extraction pipe 301 is sealed to the input end of the water pump 302. The output end of the water pump 302 is sealed to the outlet pipe 303. A check valve 304 is sealed inside the outlet pipe 303. A water delivery pipe 305 is connected to the end of the outlet pipe 303. The water pump 302 extracts water from the water storage tank 201 through the extraction pipe 301 and delivers it to the water delivery pipe 305 through the outlet pipe 303. The water can then be transported and used through the water delivery pipe 305. The check valve 304 prevents water in the water delivery pipe 305 from flowing back into the water storage tank 201 or the water pump 302.

[0028] A support frame 401 is fixedly installed on the side of the water storage tank 201 near the water pump 302. An inlet pipe 402 is welded to the outside of the support frame 401. The support frame 401 is equidistantly distributed on the outside of the inlet pipe 402. A three-hole connector 403 is sealed to one end of the inlet pipe 402 near the inspection port 204. Connecting the inlet pipe 402 to the water source facilitates water transportation. The three-hole connector 403 facilitates the diversion and transportation of water into the water storage tank 201.

[0029] A rotating head 404 is symmetrically rotatably connected to the outside of the three-hole connector 403. A sealing ring 405 is provided on the inside of the rotating head 404. A connecting pipe 406 is threadedly connected to the inside of the rotating head 404. A water inlet valve 407 is sealed inside the connecting pipe 406. The end of the connecting pipe 406 is threadedly connected to the rotating connector 502. One end of the connecting pipe 406 is threadedly connected to one end of the three-hole connector 403 through the rotating head 404. The sealing ring 405 increases the sealing of the connection. The other end of the connecting pipe 406 is connected and fixed through the rotating connector 502. Water can be injected into the water storage tank 201 for storage through the connecting pipe 406.

[0030] Working principle: According to Figures 1-5 As shown, during operation, one end of the connecting pipe 406 is threaded to one end of the three-hole connector 403 by rotating head 404, sealing ring 405 is used to increase the sealing of the connection, and the other end of the connecting pipe 406 is connected and fixed by rotating connector 502.

[0031] Water is transported by connecting the inlet pipe 402 to the water source. The water is diverted by the three-hole connector 403. The inlet valve 407 controls the opening of the connecting pipe 406, so that water is injected into the water storage tank 201 through the connecting pipe 406. During the water injection process, the activated carbon filter element 504 at the bottom of the sealing cover 501 intercepts and filters impurities in the water.

[0032] During water filling, the float level gauge 209 is used to monitor the water level inside the water storage tank 201 in real time. The anti-wave frame 208 can reduce the fluctuation of the water surface during the water filling process and prevent the fluctuation of the water surface from affecting the accuracy of the float level gauge 209. After the float level gauge 209 detects that the water storage tank 201 is full, the inlet valve 407 is used to control the connection pipe 406 to close, so as to prevent the water tank from overflowing and causing safety hazards.

[0033] When it is necessary to replace the water stored in the water tank 201, the drain pipe 206 on one side is opened through the drain valve 207, and the old water is guided by the water inlet base 205 at the bottom, so that the old water can be discharged out of the device through the drain pipe 206.

[0034] By disassembling and separating the rotary joint 502 from one end of the connecting pipe 406, and rotating the other end of the connecting pipe 406 around the three-hole joint 403 via the rotating head 404, the connecting pipe 406 is flipped upwards. The sealing cover 501 is then rotated and separated from the inspection port 204, making it easier to maintain and repair the inside of the water storage tank 201 through the inspection port 204. The water outlet screen frame 503 is then removed from the water storage tank 201 through the sealing cover 501, and the water outlet screen frame 503 is then rotated and disassembled from the sealing cover 501, thus facilitating the replacement of the activated carbon filter element 504.

[0035] The water storage tank 201 is divided into two independent parts by the partition plate 203. When the water storage tank 201 is changed for maintenance on one side, it will not interfere with the other side of the water storage tank 201. This allows the stored water to be supplied normally during the water change and prevents insufficient water supply during the water change.

[0036] Water is pumped from the water storage tank 201 by the pump 302 through the extraction pipe 301 and then transported to the water delivery pipe 305 through the outlet pipe 303. The water can then be transported and used through the water delivery pipe 305. After the water is transported, a check valve 304 is used to prevent the water in the water delivery pipe 305 from flowing back into the water storage tank 201 or the pump 302.

[0037] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
