Energy storage tank having function of fixing energy storage units

Abstract

An energy storage tank having a function of fixing energy storage units used for a working liquid includes a fixing assembly and a tank body that is for filling of the working liquid and has a bottom plate. The fixing assembly is received in the tank body and includes a fixing part to which the energy storage units are connected and an installation part that is fixed at the fixing part and disposed on the bottom plate. The installation part and the fixing part hold the energy storage units completely in the working liquid. Therefore, the energy storage units are fixed in the tank body in series or by group and distributed evenly in the working liquid such that each of the energy storage units can completely contact the working liquid to enhance energy storage efficiency of the energy storage tank.

What is claimed is:

         2 . The energy storage tank ( 10 ) according to  claim 1 , wherein the installation part ( 22 ) is a counterweight block ( 221 ). 
     
     
         3 . The energy storage tank ( 10 ) according to  claim 1 , wherein the bottom plate ( 11 ) is provided with a magnetic part ( 112 ), wherein the installation part ( 22 ) is a magnet ( 223 ), wherein the magnet ( 223 ) and the magnetic part ( 112 ) attract to each other. 
     
     
         4 . The energy storage tank ( 10 ) according to  claim 1 , wherein the bottom plate ( 11 ) is provided with a magnet ( 111 ), wherein the installation part ( 22 ) is a magnetic part ( 222 ), wherein the magnet ( 111 ) and the magnetic part ( 222 ) attract to each other. 
     
     
         5 . The energy storage tank ( 10 ) according to  claim 4 , wherein the bottom plate ( 11 ) has an internal side surface ( 13 ) and an external side surface ( 14 ), wherein the magnet ( 111 ) is installed on the internal side surface ( 13 ) or on the external side surface ( 14 ). 
     
     
         6 . The energy storage tank ( 10 ) according to  claim 1 , wherein a first hook ( 113 ) is installed on the bottom plate ( 11 ), wherein the installation part ( 22 ) is a second hook ( 224 ), wherein the first hook ( 113 ) and the second hook ( 224 ) hook to each other. 
     
     
         7 . The energy storage tank ( 10 ) according to  claim 6 , wherein the fixing assembly ( 2 ) further comprises a counterweight part ( 23 ), wherein a third hook ( 231 ) and a fourth hook ( 232 ) are disposed at two ends of the counterweight part ( 23 ), wherein the third hook ( 231 ) and the first hook ( 113 ) hook to each other, wherein the fourth hook ( 232 ) and the second hook ( 224 ) hook to each other. 
     
     
         8 . The energy storage tank ( 10 ) according to  claim 1 , wherein the fixing part ( 21 ) is a bag ( 211 ) in which the energy storage units ( 200 ) are received. 
     
     
         9 . The energy storage tank ( 10 ) according to  claim 1 , wherein the fixing part ( 21 ) is a rope ( 212 ), wherein a through hole ( 201 ) is disposed at each of the energy storage units ( 200 ), wherein the energy storage units ( 200 ) are disposed in series to the rope ( 212 ) through the through holes ( 201 ). 
     
     
         10 . The energy storage tank ( 10 ) according to  claim 1 , wherein the fixing part ( 21 ) is a rod, wherein a through hole ( 201 ) is disposed at each of the energy storage units ( 200 ), wherein the energy storage units ( 200 ) are disposed in series to the rod through the through holes ( 201 ).
