Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figures 1-6 , a ground source heat pump automatic water replenishing device, including an installation base 1. A limiting groove 13 is opened on the upper end surface of the installation base 1. A clamping groove 12 is opened on the bottom wall of the limiting groove 13, and the clamping groove 12 penetrates through the installation base 1. A limiting device is arranged in the clamping groove 12, and the output end of the limiting device is slidably clamped in the limiting groove 13. A water filling port 2 is opened on one side of the installation base 1. A sealing groove 20 is opened on the inner bottom wall of the water filling port 2. A sealing device is arranged on the inner bottom wall of the water filling port 2. The lower end surface of the installation base 1 is fixedly installed with a water replenishing bucket 3. The lower end surface of the installation base 1 is fixedly connected with a water inlet pipe 5, and the water inlet pipe 5 is communicated with the water filling port 2. A jacking device is slidably sleeved on the outer wall of the water inlet pipe 5, and the output end of the jacking device is fixedly connected with a traction device.

[0025] As Figures 1-6 shown, the implementation manner is specifically as follows: By setting up a water filling port 2, a water inlet pipe 5, a floating plate 8, a limiting device, a sealing device, a traction device and other structures, according to the drop of the water level, the jacking device can follow the water level to drop. By using the drop of the jacking device, the through groove 18 on the limiting device can be connected to the water filling port 2 through the traction device, so that the water source can enter the water inlet pipe 5 and the water replenishing bucket 3 to automatically replenish the water replenishing bucket 3, solving the problem that the traditional manual water replenishing method is not only inefficient, but also difficult to accurately master the timing and amount of water replenishment.

[0026] The limiting device includes a limiting block 4, and the limiting block 4 is slidably clamped in the limiting groove 13. A stop block 6 is fixedly installed on the lower end surface of the limiting block 4, and the stop block 6 is slidably clamped in the clamping groove 12. A through groove 18 is opened on the stop block 6, and the output end of the traction device is fixedly connected to the lower end surface of the stop block 6. By using the movement of the stop block 6, the through groove 18 can be connected to the water filling port 2. At this time, the water source can enter the water inlet pipe 5 through the through groove 18. When the through groove 18 moves out of the water filling port 2 following the stop block 6, the water source can be blocked by the stop block 6 and cannot enter the inside of the water filling port 2.

[0027] The sealing device includes two mounting blocks 14, and the two mounting blocks 14 are symmetrically and fixedly installed on the inner bottom wall of the water filling port 2. A fixed shaft 15 is rotatably connected between the two mounting blocks 14. A sealing plate 17 is fixedly installed on the outer wall of the fixed shaft 15, and the sealing plate 17 is attached to the upper end surface of the water inlet pipe 5. Two torsion springs 16 are symmetrically and fixedly connected to both sides of the sealing plate 17, and the two ends of the two torsion springs 16 far away from the sealing plate 17 are respectively fixedly connected to the inner side wall of the water filling port 2. The sealing plate 17 can seal the sealing groove 20. When the clamping block 10 is far away from the sealing groove 20, the sealing plate 17 will fit with the sealing groove 20 under the action of the torsion spring 16. At this time, it can prevent the water source from entering the water replenishing bucket 3 through the sealing groove 20.

[0028] The jacking device includes a floating plate 8, and the floating plate 8 is slidably sleeved on the outer wall of the water inlet pipe 5. The output end of the traction device is fixedly connected to the upper end surface of the floating plate 8. Two counterweight grooves are symmetrically opened on the upper end surface of the floating plate 8, and counterweight blocks can be installed in the counterweight grooves to increase the weight of the floating plate 8. A clamping block 10 is fixedly installed on the upper end surface of the floating plate 8. Two limiting rods 9 are symmetrically and fixedly installed on the lower end surface of the floating plate 8. The floating plate 8 can float above the water source in the water replenishing bucket 3, and the clamping block 10 can pass through the sealing groove 20 and push the sealing plate 17.

[0029] Both of the two limiting rods 9 are made of rubber material, and the rubber material can prevent the limiting rods 9 from damaging the water replenishing bucket 3.

[0030] Two water outlet ports 11 are symmetrically opened on the outer wall of the water inlet pipe 5, and the water source can enter the inside of the water replenishing bucket 3 through the two water outlet ports 11.

[0031] The traction device includes a storage barrel 19, and the storage barrel 19 is fixedly installed on the upper end surface of the floating plate 8. A traction rope 7 is fixedly connected inside the storage barrel 19, and one end of the traction rope 7 away from the storage barrel 19 is fixedly connected to the lower end surface of the stopper 6. When the floating plate 8 follows the water level drop, the floating plate 8 can drive the storage barrel 19 and the traction rope 7 to drop synchronously. After dropping to a certain position, the traction rope 7 can pull the stopper 6 to drop. At this time, the through groove 18 on the stopper 6 will communicate with the water filling port 2, and at this time, the water source can enter the water inlet pipe 5 through the through groove 18.

[0032] The heights of the two limiting rods 9 are both greater than the heights of the two water outlet ports 11. It should be noted that such a design can ensure that when the water source enters the inside of the water replenishing barrel 3 through the water inlet pipe 5, it will not be blocked by the floating plate 8, preventing the water source from being blocked by the floating plate 8.

[0033] When the present utility model is in use, the water source can enter the water inlet pipe 5 through the water filling port 2. Subsequently, the water source enters the inside of the water replenishing barrel 3 through the two water outlet ports 11 on the water inlet pipe 5. Subsequently, the water level in the water replenishing barrel 3 will rise. As the water level rises, the floating plate 8 will follow the water level rise. The floating plate 8 can slide on the outer wall of the water inlet pipe 5. Subsequently, the traction rope 7 will coil in the storage barrel 19. As the floating plate 8 moves, the clamping block 10 will push the sealing plate 17, and at the same time, the clamping block 10 will engage with the sealing groove 20. As the clamping block 10 moves, the clamping block 10 will abut against the top wall of the water filling port 2, and at the same time, the stopper 6 will abut against the upper end surface of the storage barrel 19. The stopper 6 will be pushed by the storage barrel 19. Subsequently, the stopper 6 will move out of the clamping groove 12. When the clamping groove 12 completely moves out of the water filling port 2, the water source will be blocked by the stopper 6. At this time, the water replenishing barrel 3 will be filled with water, and at the same time, the water source cannot enter the water replenishing barrel 3 through the water filling port 2.

[0034] As the water source is consumed, the floating plate 8 will follow the drop of the water source. The drop of the floating plate 8 will drive the clamping block 10 to disengage from the sealing groove 20. At this time, under the action of the torsion spring 16, the sealing plate 17 will drive the fixed shaft 15 to rotate until the lower end surface of the sealing plate 17 fits with the sealing groove 20. At this time, the sealing groove 20 can be sealed. As the water source is consumed, the two limiting rods 9 on the lower end surface of the floating plate 8 will contact the inner bottom wall of the water replenishing barrel 3. At this time, since the storage barrel 19 on the floating plate 8 will tighten the traction rope 7, the traction rope 7 can drive the stopper 6 to move downward. At this time, the water source can enter the water inlet pipe 5 through the through groove 18 and enter the water replenishing barrel 3 through the water inlet pipe 5. At this time, the water replenishing barrel 3 can be automatically replenished with water.

[0035] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
