Description

Technical Field

[0001] This application relates to the field of water supply equipment, and more specifically, to a wing-type variable frequency water supply unit. Background Technology

[0002] The variable frequency water supply unit monitors the pipeline pressure in real time through a pressure sensor. After comparing it with the set value, the frequency converter automatically adjusts the water pump speed. When the water consumption increases, the water pump speed is increased, and when the water consumption decreases, the water pump speed is decreased to maintain a constant water supply pressure, so that the water pump can provide different water pressure and water volume according to actual needs.

[0003] However, existing variable frequency water supply units still have the following shortcomings during use: When used outdoors, existing variable frequency water supply units usually need to be equipped with protective plates to protect the pipe interfaces of the water supply unit. Most of the existing outdoor variable frequency water supply units are fully enclosed, and these products require a lot of manpower and time for equipment maintenance and repair. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a wing-type variable frequency water supply unit, which aims to improve the problem that most existing outdoor variable frequency water supply units are fully enclosed, and that such products require a lot of manpower and time for equipment maintenance and repair.

[0005] This application provides a wing-type variable frequency water supply unit, including a water supply unit body, a protective mechanism for protecting the pipe connection is provided above the water supply unit body, and a fixing mechanism is provided above the water supply unit body.

[0006] The protective mechanism includes two sets of bases, both of which are connected to the top of the water supply unit body. Two sets of wing plates are provided above the bases, and each of the wing plates has a through hole at its top.

[0007] In one specific implementation, two sets of mounting plates are connected to the top of each of the two sets of flying wing plates, and a cover plate is rotatably connected between the two sets of mounting plates. A first inclined surface is provided on one side of the cover plate.

[0008] In the above implementation process, the wing plate can be set above the connection of the water supply unit's main pipe, which plays a certain protective role. The through hole can be used to maintain and inspect the water supply unit. The cover plate can block the through hole when the water supply unit does not need maintenance.

[0009] In one specific implementation, the top of each of the two sets of flying wing plates is connected to a circular plate, the top of the circular plate is rotatably connected to a rotating component, the bottom of the rotating component is connected to a first housing, and a first moving component is slidably connected inside the first housing.

[0010] In the above implementation process, by setting the rotating component, the first housing can be positioned on top of the cover plate by manually rotating the rotating component, and the first moving component can slide up and down inside the first housing.

[0011] In one specific implementation, a vertical rod is connected to the bottom of the first movable component, one end of the vertical rod passes through the first housing and is connected to a fixing component, a first spring is connected to the top of the first movable component, and the other end of the first spring is connected to the inner wall of the first housing.

[0012] In the above implementation process, by setting the fixing member, after the cover plate is placed above the through hole, the fixing member can be rotated by rotating the first housing. The fixing member contacts the first inclined surface, causing the first moving member to move upward inside the first housing, compressing the first spring. After the fixing member moves above the cover plate, the elastic potential energy released by the first spring fixes the cover plate above the through hole.

[0013] In one specific implementation, the fixing mechanism includes four sets of clips, with each pair of clips connected to the bottom of a set of flying wing plates, and a positioning hole is provided through one side of each of the four sets of clips.

[0014] In the above implementation process, the wing plates can be fixed above the base by the setting of the clips. When performing extensive maintenance on the water supply unit body, the two sets of wing plates can be removed from above the base, which facilitates the maintenance of the water supply unit body.

[0015] In one specific implementation, the top of the base is provided with two sets of slots, and one side of the base is connected to two sets of second housings. The interior of the second housing is slidably connected to a second moving member, and one end of the second moving member is connected to a positioning member. The positioning member passes through the base and is movably inserted into the interior of the positioning hole.

[0016] In the above implementation process, by setting the card slot, the card can be inserted into the inside of the card slot, and then the positioning member is inserted into the inside of the positioning hole, so that the card can be fixed inside the card slot, thereby fixing the flying wing plate above the base. By controlling the movement of the second moving member, the positioning member can be moved.

[0017] In one specific implementation, the other end of the second moving member is connected to a first crossbar, the other end of the first crossbar passes through the second housing and is connected to a first pull plate, and a second spring is sleeved on the outer surface of the first crossbar.

[0018] In the above implementation process, by setting the first pull plate, the first pull rod can be moved by pulling the first pull plate, which in turn can move the first moving part and compress the second spring.

[0019] In one specific implementation, a limiting groove is formed on one side of the second moving member.

[0020] In the above implementation process, by setting the limiting groove, the second moving part can be fixed inside the second housing when it moves to the designated position.

[0021] In one specific implementation, a third housing is connected to one side of the second housing, and a third moving member is slidably connected inside the third housing. One end of the third moving member is connected to a limiting member, and one end of the limiting member passes through the second housing and is movably inserted into the inside of the limiting groove. A second inclined surface is provided at one end of the limiting member.

[0022] In the above implementation process, by setting the second inclined surface, after the positioning member is completely disengaged from the positioning hole, the second moving member continues to move. The second moving member contacts the second inclined surface, driving the limiting member and the third moving member to move inside the third housing.

[0023] In one specific implementation, the other end of the third moving member is connected to a second crossbar, the other end of the second crossbar passes through the third housing and is connected to a second pull plate, and a third spring is sleeved on the outer surface of the second crossbar.

[0024] In the above implementation process, by setting the third spring, when the limiting member and the third moving member move inside the third housing, the third spring is compressed until the limiting groove moves to one side of the limiting member. The third spring releases its elastic potential energy, causing the limiting member to insert into the limiting groove and fix the second moving member. At this time, the positioning member will not reset and be inserted into the positioning hole. The operator can remove the clip from the slot and disassemble the flying wing plate. After the water supply unit body maintenance is completed, the clip is inserted into the slot. By pulling the second pull plate, the second crossbar moves, causing the third moving member to move, so that the limiting member is removed from the limiting groove. The second spring releases its elastic potential energy, causing the positioning member to insert into the positioning hole and fix the clip inside the slot, thus completing the fixation of the flying wing plate.

[0025] Compared with the prior art, the beneficial effects of this application are as follows: By setting up the protective and fixing mechanisms, the wing plate can be positioned above the pipe connection of the water supply unit body, providing a certain degree of protection. The through-hole allows for maintenance and inspection of the water supply unit body. The cover plate can block the through-hole when the water supply unit body does not require maintenance. After the cover plate is placed over the through-hole, rotating the first housing causes the fixing component to rotate, contacting the first inclined surface and causing the first moving component to move upwards inside the first housing, compressing the first spring. After the fixing component moves above the cover plate, the elastic potential energy released by the first spring fixes the cover plate above the through-hole. During extensive maintenance of the water supply unit body, pulling the first pull plate moves the first crossbar, causing the second moving component to move and disengage the positioning component from the positioning hole. After the positioning component is completely disengaged from the positioning hole, the second moving component continues to move... When the second moving part contacts the second inclined surface, it drives the limiting part and the third moving part to move inside the third housing, compressing the third spring until the limiting groove moves to one side of the limiting part. The third spring releases its elastic potential energy, causing the limiting part to insert into the limiting groove and fix the second moving part. At this time, the positioning part will not reset and be inserted into the positioning hole. The operator can then remove the clip from the slot and disassemble the wing plate. After the water supply unit body is repaired, the clip is inserted into the slot. By pulling the second pull plate, the second crossbar moves, causing the third moving part to move, causing the limiting part to disengage from the limiting groove. The second spring releases its elastic potential energy, causing the positioning part to insert into the positioning hole and fix the clip inside the slot, thus fixing the wing plate. This solves the problem that most existing outdoor variable frequency water supply units are fully enclosed, and these products require a lot of manpower and time for equipment maintenance and repair.

Detailed Implementation

[0037] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0038] Please see Figure 1 This application provides a wing-type variable frequency water supply unit, including a water supply unit body 1.

[0039] Please see Figure 1 A protective mechanism 2 is installed above the main body 1 of the water supply unit to protect the pipe connection, and a fixing mechanism 3 is installed above the main body 1 of the water supply unit.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The protective mechanism 2 includes two sets of bases 203, both of which are connected to the top of the water supply unit body 1. Two sets of flying wing plates 201 are provided above the bases 203, and through holes 204 are provided on the top of both sets of flying wing plates 201.

[0041] In the specific setup, two sets of mounting plates 206 are connected to the top of each of the two sets of wing plates 201. A cover plate 202 is rotatably connected between the two sets of mounting plates 206. A first inclined surface 207 is provided on one side of the cover plate 202. The wing plates 201 are positioned above the pipe connection of the water supply unit body 1, providing a certain degree of protection. The through holes 204 allow for maintenance and inspection of the water supply unit body 1. The cover plate 202 can block the through holes 204 when the water supply unit body 1 does not require maintenance.

[0042] In the specific configuration, the top of each of the two sets of flying wing plates 201 is connected to a circular plate 205. The top of the circular plate 205 is rotatably connected to a rotating component 208. The bottom of the rotating component 208 is connected to a first housing 2010. The first moving component 2011 is slidably connected inside the first housing 2010. The rotating component 208 can be manually rotated to position the first housing 2010 on top of the cover plate 202. The first moving component 2011 can slide up and down inside the first housing 2010.

[0043] In the specific configuration, the bottom of the first moving part 2011 is connected to a vertical rod 2013. One end of the vertical rod 2013 passes through the first housing 2010 and is connected to a fixing member 209. The top of the first moving part 2011 is connected to a first spring 2012. The other end of the first spring 2012 is connected to the inner wall of the first housing 2010. With the fixing member 209, after the cover plate 202 is placed over the through hole 204, the first housing 2010 is rotated to drive the fixing member 209 to rotate. The fixing member 209 contacts the first inclined surface 207, causing the first moving part 2011 to move upward inside the first housing 2010, compressing the first spring 2012. After the fixing member 209 moves over the cover plate 202, the elastic potential energy released by the first spring 2012 fixes the cover plate 202 over the through hole 204.

[0044] In a specific configuration, the fixing mechanism 3 includes four sets of clips 301. Each pair of clips 301 is connected to the bottom of a set of wing plates 201. Each of the four sets of clips 301 has a positioning hole 302 through it on one side. The clips 301 can fix the wing plates 201 above the base 203. When performing extensive maintenance on the water supply unit body 1, the two sets of wing plates 201 can be removed from the top of the base 203, which facilitates maintenance on the water supply unit body 1.

[0045] In a specific configuration, the top of the base 203 has two sets of slots 303, and one side of the base 203 is connected to two sets of second housings 304. The interior of the second housing 304 is slidably connected to a second moving part 305. One end of the second moving part 305 is connected to a positioning part 306. The positioning part 306 penetrates the base 203 and is movably inserted into the interior of the positioning hole 302.

[0046] In a specific configuration, the other end of the second moving part 305 is connected to the first crossbar 307. The other end of the first crossbar 307 passes through the second housing 304 and is connected to the first pull plate 309. The outer surface of the first crossbar 307 is fitted with a second spring 308. The first pull plate 309 can be used to pull the first pull plate 309, thereby moving the first pull rod and the first moving part 2011, which in turn compresses the second spring 308.

[0047] In a specific configuration, a limiting groove 3017 is provided on one side of the second moving member 305. By providing the limiting groove 3017, the second moving member 305 can be fixed inside the second housing 304 when it moves to a designated position.

[0048] In a specific configuration, a third housing 3010 is connected to one side of the second housing 304. A third moving member 3011 is slidably connected inside the third housing 3010. One end of the third moving member 3011 is connected to a limiting member 3012. One end of the limiting member 3012 passes through the second housing 304 and is movably inserted into the limiting groove 3017. A second inclined surface 3013 is provided at one end of the limiting member 3012. Through the setting of the second inclined surface 3013, after the positioning member 306 is completely disengaged from the positioning hole 302, the second moving member 305 continues to move. The second moving member 305 contacts the second inclined surface 3013, causing the limiting member 3012 and the third moving member 3011 to move inside the third housing 3010.

[0049] In a specific configuration, the other end of the third moving member 3011 is connected to a second crossbar 3014. The other end of the second crossbar 3014 penetrates the third housing 3010 and is connected to a second pull plate 3016. A third spring 3015 is sleeved on the outer surface of the second crossbar 3014. The third spring 3015 is compressed when the limiting member 3012 and the third moving member 3011 move inside the third housing 3010, until the limiting groove 3017 moves to one side of the limiting member 3012. The third spring 3015 then releases its elastic potential energy, causing the limiting member 3012 to insert into the limiting groove 3017, thus controlling the movement of the third moving member 3012. When the two moving parts 305 are fixed, the positioning part 306 will not be reset and inserted into the positioning hole 302. The staff can remove the clip 301 from the slot 303 and disassemble the flying wing plate 201. After the water supply unit body 1 is repaired, the clip 301 is inserted into the slot 303. By pulling the second pull plate 3016, the second crossbar 3014 is moved, which in turn moves the third moving part 3011, causing the limiting part 3012 to disengage from the limiting groove 3017. The second spring 308 releases its elastic potential energy, causing the positioning part 306 to be inserted into the positioning hole 302, fixing the clip 301 inside the slot 303, thus completing the fixation of the flying wing plate 201.

[0050] The working principle of the wing-type variable frequency water supply unit is as follows: When using the wing-type variable frequency water supply unit, the wing plate 201 can be placed above the pipe connection of the water supply unit body 1 to provide a certain degree of protection. Through the through hole 204, the water supply unit body 1 can be maintained and inspected. The cover plate 202 can block the through hole 204 when the water supply unit body 1 does not require maintenance. After the cover plate 202 is placed over the through hole 204, rotating the first housing 2010 drives the fixing member 209 to rotate. The fixing member 209 contacts the first inclined surface 207, causing the first moving part to rotate. When component 2011 moves upward inside the first housing 2010, it compresses the first spring 2012. After the fixing component 209 moves above the cover plate 202, the elastic potential energy released by the first spring 2012 fixes the cover plate 202 above the through hole 204. When performing extensive maintenance on the water supply unit body 1, by pulling the first pull plate 309, the first crossbar 307 moves, causing the second moving component 305 to move, which in turn causes the positioning component 306 to disengage from the positioning hole 302. After the positioning component 306 is completely disengaged from the positioning hole 302, the second moving component 305 continues to move. 5. Contact with the second inclined surface 3013 causes the limiting member 3012 and the third moving member 3011 to move inside the third housing 3010, compressing the third spring 3015 until the limiting groove 3017 moves to one side of the limiting member 3012. The third spring 3015 releases its elastic potential energy, causing the limiting member 3012 to insert into the limiting groove 3017, fixing the second moving member 305. At this time, the positioning member 306 will not reset and insert into the positioning hole 302. The operator can then disassemble the clip 301 from the clip 303 and remove the wing plate 201 for maintenance of the water supply unit body 1. After completion, insert the clip 301 into the slot 303. By pulling the second pull plate 3016, the second crossbar 3014 moves, which in turn moves the third moving part 3011, causing the limiting part 3012 to disengage from the limiting groove 3017. The second spring 308 releases its elastic potential energy, causing the positioning part 306 to insert into the positioning hole 302, thus fixing the clip 301 inside the slot 303 and completing the fixation of the wing plate 201. This solves the problem that most existing outdoor variable frequency water supply units are fully enclosed, and that such products require a lot of manpower and time for equipment maintenance and repair.

[0051] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
