DETAILED DESCRIPTION

[0014] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0015] Embodiment, please refer to Figs. 1-2The utility model provides a kind of technical scheme: an energy-saving water adding system of water adding station, including crane pipe mechanism 1 for being used to add water for sanitation vehicle 3 and the water storage tank 2 being communicated with municipal water pipeline 6 in one end;Still include high-level water tank 4;The water storage tank 2 is communicated with high-level water tank 4 by water inlet pipe 21;The water outlet pipe 41 of the lower end connection of high-level water tank 4 is communicated with crane pipe mechanism 1, is used to supply water for crane pipe mechanism 1;Stop valve 22 is equipped on the water inlet pipe 21;Water pump 5 connection suction pipe 51 is inserted into the inside of water storage tank 2, and the drain pipe 52 being connected is communicated with the upper portion of high-level water tank 4;Liquid level meter 42 is equipped in high-level water tank 4, and the liquid level meter 42 is connected with the controller circuit of water pump 5, is used to control the start-stop of water pump 5 according to the water level value obtained by liquid level meter 42.

[0016] When using, when the pressure of municipal water pipeline 6 is enough, fill the water storage tank 2 first, and then water can be supplied to high-level water tank 4;Stop valve 22 can prevent water backflow. High-level water tank 4 is higher than the water outlet of crane pipe, and water potential energy can be used to add water to sanitation vehicle 3. When the pressure of municipal water pipeline 6 is insufficient, only enough to fill the water storage tank 2 arranged on the ground. At this time, if continuously adding water to sanitation vehicle 3, the water level in high-level water tank 4 decreases, and when the water level decreases to the preset position, the low water level signal is sent by liquid level meter 42, and water pump 5 is controlled to start, and water pump 5 extracts water from water storage tank 2 to supplement high-level water tank 4. As can be seen, the system can overcome the pressure fluctuation of municipal water pipeline 6, continuously supplement water to high-level water tank 4;Reduce the working time of water pump 5, save energy consumption, also reduce the start-stop frequency of water pump 5, improve the service life of water pump 5, reduce maintenance cost. Among them, the setting of water storage tank 2 can play the role of temporary water storage, even when the pressure of municipal water pipeline 6 is very low, water can be slowly added to water storage tank 2, to ensure that enough water source is provided for adding water to sanitation vehicle 3.

[0017] In order to save space, the water pump 5 is installed at the top end of the water storage tank 2, and the distal end of the suction pipe 51 connected thereto is close to the bottom of the water storage tank 2. Water at the bottom of the water storage tank 2 can be extracted, and the space resources of the water storage tank 2 are fully utilized.

[0018] In order to cope with the situation that the pressure of municipal water pipe is too low, the connecting port for communicating with the municipal water pipeline 6 on the water storage tank 2 is located at the lower part of the water storage tank 2. Even if the pressure of municipal water pipe is insufficient to fill the water storage tank 2, as long as there is water at the bottom of the water storage tank 2, the pipe opening of the suction pipe 51 is submerged, the system can still work.

[0019] In order to save energy further, the outlet pipe 41 is provided with a spiral blade 43; the spiral blade 43 is connected with a rotating shaft 44 in the center, which penetrates the outlet pipe 41 and is connected with a generator 45, for generating electricity by using the water flow discharged from the high-level water tank 4. The electricity generated by the generator 45 is recycled to the energy storage battery module in the water filling station, which can provide electricity for the water pump 5, reducing the energy consumption of the external power supply. It is equivalent to recycling part of the water potential energy generated by the water pump 5.

[0020] In order to improve safety, due to the action of the check valve 22, the high-level water tank 4 cannot automatically release pressure. When the liquid level gauge 42 fails, it can cause the water pump 5 to continuously pressurize the high-level water tank 4, causing it to rupture. In order to avoid such failures, the high-level water tank 4 is provided with a pressure alarm 46. When the pressure of the high-level water tank 4 exceeds the standard, a warning is given to shut down the water pump 5 in time.

[0021] In a preferred embodiment, the high-level water tank 4 has multiple; one end of the water inlet pipe 21 is bifurcated to form multiple water inlet branch pipes 211, and the end of each water inlet branch pipe 211 is connected to one high-level water tank 4; one end of the drain pipe 52 is bifurcated to form multiple drain branch pipes 521, and the end of each drain branch pipe 521 is connected to one high-level water tank 4; each high-level water tank 4 is connected to one crane pipe mechanism 1; adjacent two high-level water tanks 4 are connected through a connecting pipe 47; the liquid level gauge 42 in each high-level water tank 4 is connected to the circuit of the water pump 5, so that when the liquid level of any high-level water tank 4 is lower than the preset value, the water pump 5 is controlled to start. In other words, one water storage tank 2 and one water pump 5 supply multiple high-level water tanks 4. At this time, first, the amount of high-level water storage is increased, which can better utilize the pressure of the municipal water pipe, further reducing the working time of the water pump 5 and saving energy; second, the number of water pumps 5 and water storage tanks 2 is reduced, reducing equipment cost; third, the frequency of starting the water pump 5 is reduced, and the water quantity of multiple high-level water tanks 4 can be greater than the water storage capacity of one sanitation vehicle, so that after the sanitation vehicle is filled with water, the water level of the high-level water tank 4 decreases less, thereby reducing the working frequency of the water pump 5 and further prolonging its service life.

[0022] The advantages of the present embodiment are that the system can overcome the pressure fluctuation problem of the municipal water pipeline 6, and can slowly and continuously refill the high-level water tank 4 when the sanitation vehicle is operating; when the sanitation vehicle needs to be filled with water, it can quickly fill the water, ensuring the efficiency of water filling; and can reduce the working time of the water pump 5, save energy, also reduce the start-stop frequency of the water pump 5, improve the service life of the water pump 5, and reduce maintenance cost.

[0023] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
