[0026] Embodiment

[0027] Referring to Figures 1 - 4 , an embodiment of the present utility model provides a protection device for a water pumping unit, which includes a protection unit 100, a loading and unloading unit 200, and a fixing unit 300.

[0028] The protection unit 100 includes a box body 101 and a box door 102 rotatably connected to one side wall of the box body 101. A partition 103 is fixedly connected inside the box body 101, and a water pumping unit 104 is installed on the partition 103;

[0029] The loading and unloading unit 200 includes multiple groups of electric telescopic rods 201 fixedly connected to the upper side wall of the partition plate 103 and a fixed platform 202 fixedly connected to the multiple groups of electric telescopic rods 201. A rectangular sliding groove is formed in the lower side wall of the fixed platform 202. Two telescopic slide rails 203 are respectively slidably connected in the rectangular sliding groove. A slide table 204 is slidably connected between the two telescopic slide rails 203. Multiple groups of clamping arms 205 are rotatably connected to the lower side wall of the slide table 204. A screw rod 206 is rotatably connected to one of the clamping arms 205 in each group of clamping arms 205. A straight groove opening is formed in the other clamping arm 205 in each group of clamping arms 205. Each screw rod 206 is arranged through the corresponding straight groove opening. A fastening nut 207 is threadedly connected to one end of each screw rod 206 passing through the straight groove opening. The multiple groups of clamping arms 205 jointly clamp the water pump unit 104 from above. By tightening the fastening nut 207 on the screw rod 206, the multiple groups of clamping arms 205 jointly clamp the water pump unit 104 to be installed. The electric telescopic rod 201 is started to lift the water pump unit 104 upward. By pushing the telescopic slide rail 203 to contract, the water pump unit 104 is placed into the box body 101. It is not necessary for multiple people to lift the water pump unit 104 into the box body 101, making it more convenient and fast to install the water pump unit 104 into the box body 101;

[0030] The fixing unit 300 includes a placing table 301 and a connecting column 302 fixedly connected to the lower side wall of the placing table 301. The water pump unit 104 is placed on the placing table 301. The connecting column 302 penetrates downward through the partition plate 103. A plurality of connecting pieces 303 are rotatably connected to the lower side wall of the connecting column 302. One end of each connecting piece 303 away from the connecting column 302 is rotatably connected to a clamping block 304. A plurality of rectangular openings matching the clamping blocks 304 are formed in the partition plate 103. Each clamping block 304 is slidably arranged in the corresponding rectangular opening. The plurality of clamping blocks 304 jointly clamp the four side walls of the water pump unit 104. A screw rod 109 connected by threading is penetrated through the center of the lower side wall of the box body 101. A baffle is fixedly connected to one end of the screw rod 109 close to the connecting column 302. The baffle abuts against the lower end of the connecting column 302. The water pump unit 104 clamped into the box body 101 by the clamping arms 205 makes the lower side wall of the water pump unit 104 abut against the placing table 301 through the contraction of the electric telescopic rod 201. Due to the downward pressure of the water pump unit 104 on the placing table 301, the connecting column 302 will extend downward. The downward-extended connecting column 302 makes the corresponding clamping blocks 304 approach and contract with each other on the partition plate 103 through the connecting pieces 303, jointly clamping and fixing the four side walls of the water pump unit 104, so that the water pump unit 104 remains stable and does not shake in the box body 101. By rotating the screw rod 109 at the bottom of the box body 101 to make the screw rod 109 expand and contract, the baffle on the screw rod 109 will abut against the connecting column 302 to reset the connecting column 302, so as to make the plurality of clamping blocks 304 release the clamping of the water pump unit 104;

[0031] The four side walls of the water pump unit 104 are provided with grooves. One end of each clamping arm 205 away from the sliding table 204 is fixedly connected with a protrusion matching the groove, and each protrusion is arranged to be embedded in the groove. By arranging the grooves on the side walls of the water pump unit 104, the clamping arms 205 can hold the water pump unit 104 more firmly and will not fall off. A plurality of groups of universal wheels 107 are rotatably connected to the lower side wall of the box body 101. A plurality of groups of screw columns 108 connected by threads are also arranged through the lower side wall of the box body 101. The lower side wall of each screw column 108 is fixedly connected with an anti-slip rubber pad. By arranging the universal wheels 107, it is convenient to move the water pump unit protection device. When the water pump unit protection device needs to be fixed, through the provided retractable screw columns 108, the screw columns 108 are extended to abut against the bottom surface, supporting the water pump unit protection device and making the universal wheels 107 leave the bottom surface. A rectangular ventilation opening is arranged on the lower side wall of the box body 101, and a dust-proof net 105 is fixedly arranged in the ventilation opening. A heat dissipation fan 106 is fixedly communicated with one side wall of the box body 101 away from the box door 102. By arranging the dust-proof net 105, dust is prevented from entering the box body 101. By arranging the heat dissipation fan 106, the heat generated during the operation of the water pump unit 104 is discharged from the box body 101. Anti-slip rubber pads are fixedly connected to the side walls of each clamping block 304 and the clamping arm 205 in contact with the water pump unit 104, and grid-like protrusions are arranged on each anti-slip rubber pad. By arranging the grid-like anti-slip rubber pads, the friction force between the clamping blocks 304 and the clamping arms 205 and the water pump unit 104 is increased, making the clamping more stable.

[0032] During use, by opening the box door 102, placing the water pump unit 104 on the ground beside the box body 101, manually pulling out the sliding table 204 connected by the telescopic slide rail 203 inside the box body 101, so that multiple groups of clamping arms 205 on the lower side wall of the sliding table 204 clamp the water pump unit 104, and tightening the fastening nut 207 on the screw rod 206 to make multiple groups of clamping arms 205 jointly and firmly clamp the water pump unit 104 to be installed. Then start the electric telescopic rod 201 to lift the water pump unit 104 upward, and by pushing the telescopic slide rail 203 to contract, the water pump unit 104 is placed into the box body 101. There is no need for multiple people to lift the water pump unit 104 into the box body 101, making it more convenient and fast to install the water pump unit 104 into the box body 101. The water pump unit 104 clamped into the box body 101 by the clamping arms 205 contracts the electric telescopic rod 201, so that the lower side wall of the water pump unit 104 is close to the placement table 301. Due to the downward pressure of the water pump unit 104, the connecting column 302 will extend downward. The downward-extending connecting column 302 makes the corresponding clamping blocks 304 approach and contract with each other on the partition plate 103, jointly clamping and fixing the four side walls of the water pump unit 104, so that the water pump unit 104 remains stable and does not shake inside the box body 101. During the entire installation process of the water pump unit 104, loading and unloading can be completed without the cooperation of multiple people, effectively preventing the water pump unit 104 from injuring the staff, and making the loading and unloading of the water pump unit 104 more convenient and fast.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
