Description
Technical Field
[0001] The utility model relates to the technical field of water source heat pumps, in particular to water source heat pump groundwater recharging equipment. Background Art
[0002] A water-source heat pump is an air conditioning technology that utilizes groundwater for heat exchange. It leverages the circulating nature of groundwater to achieve heat transfer and balance through the water-source heat pump unit. The water-source heat pump groundwater recharge equipment is a key component of this system, contributing to the sustainable utilization of groundwater resources and environmental protection.
[0003] The utility model patent with the authorization announcement number CN214406541U discloses a water source heat pump groundwater recharge equipment, which includes a recharge well, a water source heat pump assembly and a water storage tank. The top of the recharge well is provided with a top cover, and the two sides of the top cover are respectively connected with a recharge pipe and a water intake pipe. The bottom ends of the recharge pipe and the water intake pipe are both located inside the recharge well. The outer surface of one end of the recharge pipe located in the recharge well is sleeved with a casing, and a plurality of first water seepage holes are opened on the surface of the recharge pipe. The outer surface of the casing is provided with a plurality of first water seepage holes. A plurality of second water seepage holes are provided on the surface, and a first bevel gear is fixedly sleeved on the outer surface of the top end of the sleeve, a connecting rod is fixedly connected to the lower surface of the top cover, a sleeve is fixedly connected to the bottom end of the connecting rod, a rotating rod is rotatably connected inside the sleeve, an end of the rotating rod close to the first bevel gear is fixedly connected to the second bevel gear, an end of the rotating rod away from the first bevel gear is fixedly connected to a circular gear, an electric push-pull rod is fixedly connected to the side of the lower surface of the top cover close to the circular gear, and a rack is fixedly connected to the telescopic end of the electric push-pull rod. By setting a sleeve to be sleeved on the surface of the recharge pipe, and the recharge pipe and the sleeve surface are respectively provided with a first seepage hole and a second seepage hole, when the water intake pipe is drawing water, the electric push-pull rod is controlled to extend, and the rack will drive the second bevel gear to rotate, thereby driving the sleeve to rotate on the surface of the recharge pipe, so that the first seepage hole and the second seepage hole no longer overlap. At this time, the gravel stirred up when the water intake pipe draws water cannot enter the interior of the recharge pipe. When recharge is carried out, the electric push-pull rod is started to reset and the sleeve is reset, and then the recharge operation is carried out, which can effectively prevent the recharge pipe from being blocked and ensure the water seepage efficiency of the recharge pipe.
[0004] Although the water source heat pump groundwater recharge equipment can effectively prevent the recharge pipe from being blocked, the device still has the following problems in actual use: the device directly recharges the water source into the recharge well through the recharge pipe, but there is no corresponding water level monitoring mechanism in the recharge well. When the recharged water source enters the recharge well, it is easy to cause the recharge well to overflow, and the overflowing well water will cause water accumulation on the ground, pollution of groundwater resources and other hazards. In view of this, we propose a water source heat pump groundwater recharge equipment. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.
[0030] This embodiment provides a technical solution:
[0031] See also Figures 1-6 As shown, a water source heat pump groundwater recharge equipment includes a hollow water tank 1, a connecting pipe 2 for connecting to the water source heat pump is installed on the top of the water tank 1, and a recharge pipe 3 is installed on the front face of the water tank 1; an ultrasonic liquid level sensor 4 for measuring the water level in the recharge well is installed on the front side of the bend of the recharge pipe 3; an alarm part 5 is provided above the recharge pipe 3, the alarm part 5 includes a box body 50 with an open top, and a controller 52 is fixed to the inner bottom of the box body 50; a slot 501 is provided at the front end of the top of the box body 50, a cover plate 53 is inserted into the slot 501, and an audible and visual alarm 54 is installed on the top of the cover plate 53; two symmetrical clamps 51 are installed on the front and rear sides of the bottom of the box body 50, and the recharge pipe 3 is clamped by the two adjacent clamps 51, and connecting bolts 510 are threadedly connected at both ends between the two adjacent clamps 51 above and below, and the clamp 51 located above is fixedly connected to the bottom of the box body 50.
[0032] Furthermore, a housing 55 is fixedly mounted on the front end of the housing 50. The rear end of the housing 55 is open. A guide rod 56 is fixed within the opening of the housing 55. A spring 57 is sleeved on the outside of the guide rod 56. A slider 59 is slidably mounted on the outside of the guide rod 56. The top end of the spring 57 abuts against the slider 59. A limit plate 58 is fixed to the rear end of the slider 59. The upper and lower ends of the limit plate 58 pass through the housing 55 and are slidably connected to the housing 55. The top end of the limit plate 58 abuts against the front end of the cover 53. This design facilitates the use of the limit plate 58 to limit the position of the cover 53, preventing the cover 53 from detaching from the housing 50 and ensuring the secure installation of the sound and light alarm 54. This design also facilitates the disassembly and assembly of the cover 53, making it convenient to open the housing 50 for inspection and maintenance of the controller 52.
[0033] In this embodiment, a plurality of heat dissipation slots 500 are provided on the rear end surface of the housing 50 . The cross-section of the heat dissipation slots 500 is rectangular. The provision of the heat dissipation slots 500 facilitates the circulation of air inside and outside the housing 50 and facilitates the heat dissipation of the controller 52 .
[0034] In this embodiment, a support plate 33 is provided at the bend of the recharge pipe 3. The ultrasonic liquid level sensor 4 is fixedly connected to the support plate 33 by bolts. The recharge pipe 3 passes through the support plate 33 and is fixedly connected to the support plate 33. A mounting plate 31 is fixed to the rear end of the support plate 33. Anchor bolts 32 are inserted into the inner wall of the recharge well at each of the four corners of the mounting plate 31. The anchor bolts 32 penetrate the inner wall of the recharge well. This design facilitates stable support of the ultrasonic liquid level sensor 4 by the support plate 33, ensuring the stable installation of the ultrasonic liquid level sensor 4.
[0035] In this embodiment, both side walls of the slot 501 are provided with limiting grooves 502, and both ends of the cover plate 53 are fixed with limiting bars 530, which are plugged into the limiting grooves 502. The arrangement of the limiting bars 530 and the limiting grooves 502 ensures the installation stability of the cover plate 53.
[0036] In this embodiment, a pressure plate 580 is fixed to the bottom of the limit plate 58. The limit plate 58 and the pressure plate 580 are integrally formed. The integrally formed limit plate 58 and the pressure plate 580 provide a stronger connection, ensuring the service life of the limit plate 58 and the pressure plate 580. The arrangement of the pressure plate 580 facilitates pressing the limit plate 58 to adjust its position.
[0037] In this embodiment, a valve 30 is installed at the rear end of the recharging pipe 3. The valve 30 is a ball valve. The valve 30 is convenient for controlling the opening and closing of the recharging pipe 3, meeting the needs of use.
[0038] It should be added that a through hole is provided on one side of the bottom of the box body 50 in this embodiment. The provision of the through hole facilitates the passage of wires, etc., thereby facilitating electrical connection between the controller 52 and the power supply, the sound and light alarm 54 and the ultrasonic liquid level sensor 4, thereby meeting the requirements of use.
[0039] It is worth noting that the sound and light alarm 54 and the ultrasonic liquid level sensor 4 involved in this embodiment are existing conventional technologies and will not be described in detail here.
[0040] When in use, the water source heat pump discharges groundwater, which enters the water tank 1 through the connecting pipe 2. Then the user opens the valve 30, and the groundwater is recharged into the recharge well through the recharge pipe 3, and the water level in the recharge well rises.
[0041] When the ultrasonic liquid level sensor 4 detects that the water level in the recharge well has reached a threshold value, the ultrasonic liquid level sensor 4 sends a signal to the controller 52, and the controller 52 controls the operation of the sound and light alarm 54. The sound and light alarm 54 simultaneously issues a sound and light warning, and the staff closes the valve 30 and stops the water source heat pump, and the groundwater stops being recharged into the recharge well.
[0042] When the box body 50 needs to be opened, the user first presses the pressure plate 580 downward, and the pressure plate 580 drives the limit plate 58 and the slider 59 to move downward. The slider 59 slides along the guide rod 56, and the spring 57 is compressed. At this time, the top end of the limit plate 58 is separated from the front end of the cover plate 53. Then the user pushes the cover plate 53 to the front side, and the cover plate 53 is separated from the slot 501, and the box body 50 is opened.
[0043] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
