Description

Technical Field

[0001] The utility model relates to the technical field of temperature measuring devices, in particular to a ground source heat pump temperature measuring device. Background Art

[0002] A ground source heat pump is a device that transfers low-grade heat energy to high-grade heat energy by inputting a small amount of high-grade energy (such as electric energy) from shallow terrestrial energy. Generally, when a ground source heat pump consumes 1 kWh of energy, users can obtain more than 4.4 kWh of heat or cold.

[0003] The Chinese utility model with the authorization announcement number CN218211637U discloses a ground temperature monitoring device for a ground source heat pump. When this device is in use, the effective fixation of the temperature measuring component is achieved through a horizontal plate, avoiding the situation where the temperature measuring component shakes during the up and down movement, resulting in frequent collisions between the temperature measuring component and the inner wall of the vertical temperature measuring hole, which may cause damage to the temperature measuring component. However, during specific use, this device has certain defects. For example, during the use of the horizontal plate, friction and mechanical wear with the inner wall of the pipeline are likely to cause a decrease in accuracy or damage, thereby affecting the fixation effect of the temperature measuring component, and may lead to loosening of the component, thus affecting the temperature measurement accuracy. Therefore, it is necessary to redesign a ground source heat pump temperature measuring device to address the above problems. Summary of the Utility Model

A threaded rod is rotatably connected between two of the side plates. A slider is threadedly connected to the threaded section of the threaded rod. The slider is connected to a slide plate through a connection mechanism. A connecting rod is slidably connected to the outer wall of the slide plate. A pulley is fixedly connected to the end of the connecting rod. Two suspension rings are installed at the upper end of the temperature measuring device body.

[0007] Preferably, the connection mechanism includes sliding rods fixedly connected to the outer walls on both sides of the slider. The outer walls of the sliding rods are L-shaped, and the ends of the sliding rods are fixedly connected to the slide plate.

[0008] Preferably, a limiting rod is fixedly connected between the two side plates, and the slider is slidably connected to the outer wall of the limiting rod.

[0022] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Referring to Figures 1-5 , a ground source heat pump temperature measuring device includes a temperature measuring device body 1. Multiple side plates 2 are fixedly connected to the upper end of the temperature measuring device body 1. Multiple side plates 2 are located on the same horizontal plane in pairs. A threaded rod 6 is rotatably connected between two side plates 2. A slider 8 is threadedly connected to the threaded section of the threaded rod 6. The slider 8 is connected to a sliding plate 10 through a connecting mechanism. The outer wall of the sliding plate 10 is slidably connected to a connecting rod 14. A pulley 11 is fixedly connected to the end of the connecting rod 14. Two lifting rings 3 are installed at the upper end of the temperature measuring device body 1; the pulley 11 can reduce the friction generated due to direct sliding, which helps to reduce the resistance during the adjustment of the device and make the adjustment process smoother. At the same time, compared with the horizontal plate, its wear and loss are lower.

[0024] The connecting mechanism includes sliding rods 9 fixedly connected to the outer walls on both sides of the slider 8. The outer walls of the sliding rods 9 are L-shaped. The ends of the sliding rods 9 are fixedly connected to the sliding plate 10. A limiting rod 7 is fixedly connected between two side plates 2. The slider 8 is slidably connected to the outer wall of the limiting rod 7. A limiting block 12 is fixedly connected to the end of the connecting rod 14. The radius of the limiting block 12 is larger than the radius of the connecting rod 14. A spring 13 is sleeved on the outer wall of the connecting rod 14. One end of the spring 13 is fixedly connected to the sliding plate 10, and the other end of the spring 13 is fixedly connected to the limiting block 12. Bevel gears 5 are rotatably connected to the outer walls of multiple side plates 2. The bevel gears 5 are coaxially fixedly connected to the adjacent threaded rods 6. Multiple bevel gears 5 are meshed with each other. A servo motor 4 is fixedly connected to the outer wall of one of the side plates 2. The end of the output shaft of the servo motor 4 is coaxially fixedly connected to the threaded rod 6; the setting of the threaded rod 6 can synchronously adjust the positions of multiple pulleys 11, so as to flexibly adjust according to different pipe inner diameters; it should be noted that the connection method, installation means, and technical functions of the set temperature measuring device body 1 are all mature technologies and have nothing to do with the design purpose of this solution, so they will not be described in detail.

[0025] In the present invention, when the device is specifically used: First, connect the rope to the lifting ring 3, and then hoist the temperature measuring device body 1 into the vertical temperature measuring hole of the ground source heat pump system. Start the servo motor 4, and drive the threaded rod 6 to rotate through its output shaft. Since the bevel gears 5 are meshed with each other, all the threaded rods 6 will rotate synchronously, pushing the slider 8 on the threaded section to slide on the outer wall of the limiting rod 7. The slider 8 drives the sliding plate 10 and the pulley 11 at the end to move. Through the smooth sliding of the pulley 11, it contacts the inner wall of the pipe until it does, reducing the friction caused by direct sliding, making the position adjustment of the temperature measuring component more stable, and avoiding the wear problem caused by excessive friction in the traditional horizontal plate design.

[0026] During the sliding process, the spring 13 on the outer wall of the connecting rod 14 provides a buffering effect, further reducing the vibration of the temperature measuring component caused by rapid movement or external force.

[0027] The temperature measuring component is fixed at a specific depth position. Due to the stable action of the pulley 11 and the connecting rod 14, the temperature measuring component will not shake or shift during the temperature measurement process, ensuring the accuracy of the temperature measurement data.

[0028] When it is necessary to monitor the temperature at different depths, the servo motor 4 can be started again, and the rotation direction and angle of the threaded rod 6 can be adjusted according to the need, so as to realize the re-adjustment of the position of the pulley 11.

[0029] As mentioned above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
