Description

Technical Field

[0001] This invention relates to the field of air source heat pump unit technology, and in particular to an environmentally friendly engine-driven air source heat pump unit. Background Technology

[0002] Engine-driven air source heat pump units are a type of efficient and environmentally friendly air conditioning equipment. The condenser on the outer casing of an air source heat pump unit is an exposed design. This means that the accumulation of dust on the surface will lead to a decrease in condensation efficiency, thus affecting the performance and efficiency of the entire heat pump system. This not only means that the heat pump needs to consume more energy to maintain normal operation, but also, in areas where electricity mainly comes from environmentally unfriendly energy sources such as coal-fired power plants, this increased energy consumption will indirectly lead to more greenhouse gas emissions and other environmental pollutants, which is detrimental to environmental protection. Typically, manual cleaning of the condenser surface using high-pressure water jets or soft brushes is required. However, cleaning with soft brushes is inefficient, while high-pressure water jet cleaning can easily affect the equipment and the surrounding environment. Summary of the Invention

[0012] Preferably, the exhaust pipe and branch pipe extend through one side of the engine-driven air source heat pump unit to the interior, and the branch pipe is equipped with a dust filter structure for collecting dust in the collection box.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The two motors on both sides drive the rotating rods and two winding wheels to rotate. The two winding wheels pull the connected ropes and rods, pulling the shielding cloth out from inside the winding shell. The two rods move in opposite directions to shield the metal mesh frame. After shielding the metal mesh frame, the magnetic pieces 1 and 2 on the shielding cloth are misaligned, and magnetic piece 1 will adhere to the metal mesh frame, improving the sealing of the top and bottom sides and reducing the possibility of dust flying out during cleaning and polluting the surrounding environment. During recycling, the motor drives a winding roller to rotate, and through the meshing of two gears, it drives another winding roller to rotate, so that the shielding cloth on both sides is pulled back at the same time. At the same time as recycling, magnetic pieces 1 and 2 generate mutual repulsion force, causing the shielding cloth to fluctuate during winding and shaking off surface impurities.

[0015] The air pump is started, drawing air through the inlet pipe and branch pipe, and then delivering airflow through the outlet pipe and two telescopic pipes to the two cleaning pipes to clean the condenser surface. Meanwhile, the branch pipe and connecting pipe draw air into the two sets of collection boxes, and the filter structure on the branch pipe achieves the suction work, collecting the dust blown off by the adapter components into the collection box, improving the cleaning recovery effect.

[0016] After the metal mesh frame is covered, the connecting shafts and movable plates on both sides are pulled together by the use of hydraulic cylinders. At the same time, the upper side of the collection box covered by the movable plates on both sides is opened to facilitate the entry and collection of dust. Simultaneously, two sets of electric sliding tables drive the cleaning air pipe to rotate along the fixed plate, so that the nozzles on the lower cleaning air pipe are close to the lower side of the condenser. With the two sets of nozzles tilting upward and downward, the dust on the surface of the condenser is blown off. The two sets of nozzles tilted reduce the chance of the blown dust falling back onto the condenser. The tilt of the condenser and the arc-shaped guide on the lower side of the partition plate blow the dust towards the metal mesh frame and then into the collection box for collection. The elastic engagement of several arc-shaped spring pieces and arc-shaped grooves makes it easy to adjust the angle of the two sets of nozzles blowing on the condenser. Attached Figure Description

[0031] Please see Figures 1-11 This invention provides an embodiment of an environmentally friendly engine-driven air source heat pump unit, comprising an engine-driven air source heat pump unit 1, with two metal protective mesh frames 2 respectively installed on the front and rear sides of the engine-driven air source heat pump unit 1, a condenser 3 fixedly installed inside the upper side of the engine-driven air source heat pump unit 1, and two collection boxes 4 fixedly installed on the front and rear sides of the engine-driven air source heat pump unit 1, with boxes 5 installed on the outer shell of the engine-driven air source heat pump unit 1 near the two collection boxes 4, and two metal protective mesh frames. A shielding assembly 6 is installed near the middle of one end of the frame 2. Adaptor assemblies 7 are installed on the inner walls of both sides of the engine-driven air source heat pump unit 1 near the front and rear sides of the condenser 3. A cleaning assembly 8 is installed on one side of the engine-driven air source heat pump unit 1. The shielding assembly 6 includes a winding shell 61 fixedly mounted on the metal mesh frame 2. Two winding rollers 62 are rotatably mounted on the inner side of the winding shell 61. A shielding cloth 63 is wound up on the outer side of each of the two winding rollers 62. Gears 64 are fixedly mounted on the upper and lower sides of each of the two winding rollers 62. The winding shell 61... Openings 65 are provided on both sides corresponding to the positions of the shielding cloth 63. Several magnetic pieces 66 are fixedly installed at one end of each shielding cloth 63 near the top and bottom. A pull rod 67 is fixedly installed at one end of each shielding cloth 63. A motor 68 is fixedly installed at the upper end of the engine-driven air source heat pump unit 1 near the position corresponding to a winding roller 62. Fixing strips 69 are fixedly installed on the upper and lower sides of the metal protective mesh frame 2 at the positions corresponding to the magnetic pieces 66. Several magnetic pieces 610 are fixedly installed on the inner side of each fixing strip 69. The metal protective mesh frame 2 corresponds to the condenser 3. Support bars 611 are fixedly installed near the corners on both sides of the end. Rotating rods 612 are rotatably installed on the inner side of the two support bars 611. Winding wheels 613 are fixedly installed on the upper and lower sides of the two rotating rods 612. Pull ropes 614 are fixedly installed between the four winding wheels 613 and the corresponding two pull rods 67. Limit sleeves 615 are fixedly installed at the position of the metal protective net frame 2 near the pull rope 614 at one end of the condenser 3. Motor 616 is fixedly installed at the position of the upper end of the engine-driven air source heat pump unit 1 corresponding to the position of the rotating rod 612.

[0032] One of the two take-up rollers 62 is fixedly connected to the rotating shaft of motor 68. The two gears 64 on the upper and lower sides of the two take-up rollers 62 are meshed. The inner end of the shielding cloth 63 is fixedly connected to the take-up roller 62. The shielding cloth 63 passes through the opening 65 and is connected to the pull rod 67. When the two shielding cloths 63 completely cover the metal protective net frame 2, the magnetic sheet 66 and the magnetic sheet 610 are staggered. When the magnetic sheet 66 and the magnetic sheet 610 are aligned, they repel each other. The rotating rod 612 passes through the upper side of the engine-driven air source heat pump unit 1 and is fixedly connected to the rotating shaft of motor 616. The limiting sleeve 615 is set on one side of the take-up roller 613 and is sleeved on the outside of the pull rope 614.

[0033] The two motors 616 on both sides drive the rotating rod 612 and the two take-up wheels 613 to rotate. The two take-up wheels 613 pull the connected pull rope 614 and pull rod 67, pulling the shielding cloth 63 out from the inside of the take-up shell 61. The two pull rods 67 move in opposite directions to shield the metal protective net frame 2. After shielding the metal protective net frame 2, the magnetic piece 66 on the shielding cloth 63 is misaligned with the magnetic piece 610, and the magnetic piece 66 will then be attracted to the metal protective net frame 2. The upper and lower sides are sealed to reduce dust from flying out during cleaning and thus polluting the surrounding environment. During recycling, a motor 68 drives a winding roller 62 to rotate. Through the meshing of two gears 64, another winding roller 62 is driven to rotate, so that the shielding cloths 63 on both sides are pulled back at the same time. At the same time, the magnetic sheet 66 and the magnetic sheet 610 generate mutual repulsion force, causing the shielding cloth 63 to fluctuate during winding and shake off surface impurities.

[0034] The adapter component 7 includes two fixed plates 71 mounted on the inner walls of both sides of the engine-driven air source heat pump unit 1 near the upper side. Connecting rods 72 are rotatably mounted inside the two fixed plates 71. Electric slides 73 are fixedly mounted at opposite ends of the two connecting rods 72. Slide seats 74 are mounted below the two electric slides 73. Connecting sleeves 75 are fixedly mounted at opposite ends of the two slide seats 74. Cleaning air pipes 76 are movably mounted inside the two connecting sleeves 75. Several arc-shaped spring pieces 77 are fixedly mounted on the outer sides of the rotating shafts on both sides of the cleaning air pipes 76. Arc-shaped grooves 78 are formed on the inner walls of the two connecting sleeves 75 corresponding to the positions of the arc-shaped spring pieces 77. Two nozzles 79 are fixedly installed on one side of the cleaning air pipe 76. Two electric sliding tables 73 are fixedly installed with fixed plates 710 near the lower side of opposite ends. A round shaft 711 is fixedly installed at the front end of each of the two fixed plates 710. A connecting sleeve rod 712 is sleeved on the outside of each of the two round shafts 711. A movable plate 713 is fixedly installed at the lower end of each of the two connecting sleeve rods 712. A partition plate 714 is fixedly installed at the lower end of the condenser 3 near the upper side of the two movable plates 713. Two hydraulic cylinders 715 are fixedly installed at the lower end of the two partition plates 714. A connecting shaft 716 is fixedly installed at the lower end of each of the two movable plates 713 at the position corresponding to the telescopic rod of the hydraulic cylinder 715.

[0035] The arc-shaped spring piece 77 is engaged with the arc-shaped groove 78, the two nozzles 79 are inclined vertically, the round shaft 711 is slidably connected to the connecting sleeve rod 712, the movable plate 713 is slidably connected to the inner wall of the engine-driven air source heat pump unit 1, the movable plate 713 is attached to the bottom of the partition plate 714, the lower corner of the partition plate 714 is arc-shaped, and the telescopic rods on both sides of the connecting shaft 716 are fixedly connected to the two connecting shafts 716 corresponding to the lower ends of the two movable plates 713.

[0036] After the metal mesh frame 2 is covered, the hydraulic cylinder 715 pulls the connecting shaft 716 and the movable plate 713 on both sides closer together, and at the same time opens the upper side of the collection box 4 covered by the movable plates 713 on both sides, so that dust can enter for collection. At the same time, the two sets of electric slides 73 drive the cleaning air pipe 76 to rotate along the fixed plate 71, so that the nozzle 79 on the lower cleaning air pipe 76 is close to the lower side of the condenser 3. With the two sets of nozzles 79 blowing upward and downward, the dust on the surface of the condenser 3 is blown off. The two sets of nozzles 79 are tilted to reduce the chance of the blown dust falling back onto the condenser 3. The tilt of the condenser 3 and the arc-shaped guide on the lower side of the partition plate 714 blow the dust towards the metal mesh frame 2 and then into the collection box 4 for collection. The elastic engagement of several arc-shaped spring pieces 77 and arc-shaped grooves 78 makes it easy to adjust the angle of the two sets of nozzles 79 blowing on the condenser 3.

[0037] The cleaning component 8 includes an air pump 81 fixedly installed at one end of the engine-driven air source heat pump unit 1. An air outlet pipe 82 is fixedly installed at the upper air outlet end of the air pump 81. Telescopic pipes 83 are fixedly installed between the two sides of the air outlet pipe 82 and two cleaning air pipes 76, respectively. An air inlet pipe 84 is fixedly installed at the lower side of the air pump 81. A connecting pipe 85 is fixedly installed between the two collection boxes 4. A branch pipe 86 is fixedly installed between the connecting pipe 85 and the air inlet pipe 84. A protective shell 87 is fixedly installed on one section of the engine-driven air source heat pump unit 1 near the outer side of the air pump 81.

[0038] The exhaust pipe 82 and the branch pipe 86 pass through one side of the engine-driven air source heat pump unit 1 to the inside. The branch pipe 86 is equipped with a dust filter structure to collect dust in the collection box 4.

[0039] The air pump 81 is started, and air is drawn in through the air inlet pipe 84 and the branch pipe 86. The air is then delivered to the two cleaning air pipes 76 through the air outlet pipe 82 and the two telescopic pipes 83 to clean the surface of the condenser 3. Meanwhile, the branch pipe 86 and the connecting pipe 85 are used to draw air in the two sets of collection boxes 4. The filter structure on the branch pipe 86 is used to achieve the air intake work, and the dust blown off by the adapter component 7 is collected in the collection box 4 to improve the cleaning recovery effect.

[0040] Working principle: During cleaning, the motors 616 on both sides first drive the rotating rod 612 and the two winding wheels 613 to rotate. The two winding wheels 613 pull the connected rope 614 and lever 67, pulling the covering cloth 63 out from the inside of the winding shell 61. The two levers 67 move in opposite directions to cover the metal mesh frame 2. After the metal mesh frame 2 is covered, the magnetic sheet 66 on the covering cloth 63 is misaligned with the magnetic sheet 610. The magnetic sheet 66 then adheres to the metal mesh frame 2, improving the sealing of the upper and lower sides and reducing dust flying out during cleaning. This process, which pollutes the surrounding environment, is addressed during recycling. Motor 68 drives a winding roller 62 to rotate, and the meshing of two gears 64 drives another winding roller 62 to rotate, simultaneously pulling back the two protective fabrics 63. During this retraction, magnetic plates 66 and 610 generate mutual repulsion, causing the protective fabrics 63 to fluctuate and shake off surface impurities. Additionally, air pump 81 is activated, drawing air through inlet pipe 84 and branch pipe 86, and then delivering airflow through outlet pipe 82 and two telescopic pipes 83 into two cleaning air pipes 76 to clean the fabric. The surface of the condenser 3 is cleaned, while the branch pipe 86 and connecting pipe 85 are used for air extraction in the two sets of collection boxes 4. The filter structure on the branch pipe 86 is used to achieve air extraction, collecting the dust blown off by the adapter component 7 into the collection box 4, improving the cleaning recovery effect. After the metal protective mesh frame 2 is covered, the connecting shaft 716 and the movable plate 713 on both sides are pulled together by the use of the hydraulic cylinder 715. At the same time, the upper side of the collection box 4 covered by the movable plates 713 on both sides is opened to facilitate the entry and collection of dust. At the same time, the two sets of electric slides 73 drive the cleaning air pipe 76 along the fixed plate 71. The nozzle 79 on the lower cleaning air pipe 76 is rotated so that it is close to the lower side of the condenser 3. The two sets of nozzles 79 are tilted upward and downward to blow the dust off the surface of the condenser 3. The tilted nozzles 79 reduce the chance of the blown dust falling back onto the condenser 3. The tilt of the condenser 3 and the arc-shaped guide on the lower side of the partition plate 714 blow the dust towards the metal guard frame 2 and then into the collection box 4 for collection. The elastic engagement of several arc-shaped spring pieces 77 and arc-shaped grooves 78 makes it easy to adjust the angle of the two sets of nozzles 79 blowing on the condenser 3.

The condenser 3 is inclined on both sides, and its working principle is already known technology. The appropriate model is selected according to actual use, so it will not be explained in detail.
