Description

Technical Field

[0001] The utility model relates to the technical field of air heat source pumps, in particular to an air intake regulating device for an air heat source pump. Background Art

[0002] Air source heat pump is an energy-saving device that uses high-level energy to make heat flow from low-level heat source air to high-level heat source. It is a form of heat pump. As the name implies, heat pump is like a pump that can convert low-level heat energy that cannot be directly used into high-level heat energy that can be used, so as to achieve the purpose of saving some high-level energy; air is the main absorption object of the low-level heat source of the heat pump, so the amount of heat generated by the air source heat pump is mainly determined by the amount of air sucked by the fan. In the prior art, the air source heat pump is a fan set at the top of the body that sucks the outside air into the body through the air inlet, and further transports it to the air handling unit in the body for heat conduction. In windy weather, due to the fast horizontal wind speed outside, the pressure in the air inlet of the air source heat pump increases. At this time, due to the pressure difference between the inside and outside of the body, the amount of air sucked into the body by the fan is reduced, resulting in the air source heat pump being unable to obtain sufficient air from the outside in time when a large amount of heating is needed, which will increase the operating load of the air source heat pump and increase its maintenance cost.

[0003] After searching, Chinese patent CN218993732U discloses an air intake regulating device for an air heat source pump, comprising a vertically arranged air heat source pump body, a circular air inlet cylinder vertically installed on the top of the air heat source pump body, an air inlet port opened on the side wall of the air inlet cylinder, a shielding piece matching the air inlet port installed on the side wall of the air inlet cylinder, a driving opening device arranged on the shielding piece, and the air inlet port is used to increase the amount of air entering the air heat source pump body; the beneficial effects of the utility model: the air intake amount of the air heat source pump body is effectively increased by opening the air inlet port on the side wall of the air inlet cylinder, and sufficient air energy can be converted when a large amount of heating is required.

[0004] However, the air intake regulating device of the air heat source pump of the utility model realizes the air intake regulation through the independent operation of multiple cylinders. Although this method can realize the air intake regulation, the installation of multiple cylinders will not only increase the use cost, but also the cylinders for air intake regulation are located inside the equipment, which is not only difficult to maintain, but also increases the installation volume. Therefore, it cannot meet the production needs. Therefore, an air intake regulating device of the air heat source pump is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3An air intake regulating device for an air heat source pump comprises an air heat source pump body 1 and an air intake cylinder 2 installed vertically on the top of the air heat source pump body 1, a shell 3 is arranged on the outer wall of the air intake cylinder 2, and an air intake regulating device is arranged inside the shell 3. A mounting plate 5 connected to the air intake cylinder 2 is welded to the outside of the shell 3, and mounting bolts 16 are arranged inside the mounting plate 5, and the mounting plate 5 is mounted on the outside of the air intake cylinder 2 through the mounting bolts 16. By setting the mounting bolts 16, the shell 3 can be disassembled and assembled, which is convenient for later maintenance.

[0023] It should be noted that the air heat source pump body 1 belongs to conventional technology known to the public in the prior art, so its specific structural composition and working principle will not be described in detail in this article.

[0024] Among them, the air intake adjustment device includes a shielding structure and a driving structure. The shielding structure includes an adjustment disk 6 arranged inside the shell 3, a shielding block 7 rotatably connected to the inside of the shell 3, and a connecting rod 8 rotatably connected between the adjustment disk 6 and the shielding block 7; a connected ventilation hole 12 is opened on the side of the air inlet cylinder 2 and the inside of the shell 3, and an air inlet pipe 4 connected to the ventilation hole 12 is fixedly installed on the side of the shell 3 away from the air inlet cylinder 2.

[0025] In this embodiment, the driving structure includes a driven gear 9 fixedly mounted on the outside of the adjustment disk 6, a reduction motor 10 fixedly mounted inside the housing 3, and a transmission gear 11 fixedly mounted on the output shaft of the reduction motor 10 and meshed with the driven gear 9. By starting the reduction motor 10 to drive the transmission gear 11 to rotate, the transmission gear 11 meshes with the driven gear 9 to drive the adjustment disk 6 and drive the shielding block 7 to rotate through the connecting rod 8. Through the back and forth rotation of the adjustment disk 6, the four shielding blocks 7 are unfolded or converged to adjust the size of the ventilation hole 12. When the four shielding blocks 7 are unfolded, the wind generated horizontally at this time enters the body of the heat source pump body 1 through the ventilation hole 12, and converges with the air sucked into the heat source pump body 1 vertically downward, and is finally transported to the inside of the heat source pump body 1 under the suction of the fan, which effectively solves the problem of low efficiency of the method of realizing air intake adjustment by the separate operation of multiple cylinders.

[0026] In this embodiment, a limiting assembly for guiding the adjustment disk 6 is provided inside the housing 3, and the limiting assembly includes a fixing rod 13 fixedly mounted on the inner wall of the housing 3, and a limiting shaft 14 slidably connected to the adjustment disk 6 is welded on the side of the fixing rod 13 close to the adjustment disk 6, and a sliding opening 15 adapted to the limiting shaft 14 is provided inside the adjustment disk 6, and the limiting shaft 14 is slidably connected to the sliding opening 15. Through the arrangement of the limiting shaft 14 and the sliding opening 15, the adjustment disk 6 can be stably rotated, ensuring that the four blocking blocks 7 can stably adjust the size of the ventilation hole 12.

[0027] It should be noted that the number of shielding blocks 7 and connecting rods 8 in the shielding structure are both four, the outer shape of the shielding block 7 is an arc block of a quarter of a circle, the four shielding blocks 7 form a round circle, and the four shielding blocks 7 are adapted to the ventilation holes 12. The number of the limiter components is four, and the sliding opening 15 is ring-shaped.

[0028] The working principle of the above embodiment is:

[0029] When in use, the shell 3 is installed at the ventilation hole 12 of the air inlet tube 2 by installing the bolts 16, and the reduction motor 10 is started to drive the transmission gear 11 to rotate. The transmission gear 11 is engaged with the driven gear 9 to drive the adjusting disk 6 and the blocking block 7 to rotate through the connecting rod 8. The four blocking blocks 7 are expanded or converged by the back and forth rotation of the adjusting disk 6 to adjust the size of the ventilation hole 12. When the four blocking blocks 7 are expanded, the wind generated horizontally at this time enters the body of the heat source pump body 1 through the ventilation hole 12, and merges with the air sucked into the heat source pump body 1 vertically downward, and is finally transported to the inside of the heat source pump body 1 under the suction of the fan.

The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.
