[0019] Example 1, with reference to Figure 1-4 A pipe network type heptafluoropropane gas fire extinguishing device includes a support plate 1, a middle plate 101 and a top plate 102. The middle plate 101 is fixed on the top of the support plate 1, and the top plate 102 is fixed on the top of the middle plate 101. It is characterized in that the left and right sides of the front and rear ends of the support plate 1, the middle plate 101 and the top plate 102 are fixed with an outer frame 2, the interior of the outer frame 2 is embedded with a sliding plate 201 and a return spring 202, and the inner wall of the sliding plate 201 is fixed with a clamping block 2 03. The left and right ends of the support plate 1 are embedded with the chassis plate 204, the left and right ends of the middle plate 101 and the top plate 102 are embedded with the clamping plate 3, the front and rear ends of the chassis plate 204 and the clamping plate 3 are transversely fixed with connecting strips 301, the front and rear ends of the upper surface of the clamping plate 3 are transversely embedded with bidirectional screws 4, the front and rear ends of the left and right sides of the inside of the clamping plate 3 are embedded with fixing plates 401, and the chassis plate 204 and the clamping plate 3 are vertically embedded with HFC-227ea gas storage bottles 5.

[0020] The sliding plate 201 slides back and forth in the outer frame 2, and the supporting plate 1, the middle plate 101 and the sliding plate 201 in the top plate 102 are connected into a whole by a connecting rod;

[0021] The sliding plates 201 are connected together by a connecting rod. When the connecting rod is pulled, the sliding plates 201 in the three outer frames 2 can slide simultaneously, driving the clamping block 203 to unlock the chassis plate 204 and the clamping plate 3.

[0022] The left and right ends of the support plate 1, the middle plate 101 and the top plate 102 are provided with mounting openings that fit with the chassis plate 204 and the clamping plate 3. The chassis plate 204 and the clamping plate 3 slide horizontally left and right in the mounting openings.

[0023] By pulling the connecting rod, the sliding plate 201 drives the clamping block 203 to move out of the connection port of the connecting strip 301. The sliding plate 201 squeezes the return spring 202 at one end and deforms it. At this time, the HFC-227ea gas storage bottle 5 together with the clamping plate 3 and the base plate 204 can be removed from one end of the device. After the clamping plate 3 and the base plate 204 are removed, the HFC-227ea gas storage bottle 5 can be replaced and repaired.

[0024] The chassis plate 204 and the connecting strips 301 at the front and rear ends of the clamping plate 3 are both provided with connection ports, and the clamping block 203 at the other end of the sliding plate 201 is just embedded in the connection port, and the clamping block 203 fits in the connection port;

[0025] After the replacement and maintenance is completed, the clamping disc 3 is nested in the middle part 5 and the upper part of the heptafluoropropane gas storage bottle, and the chassis plate 204 is nested in the bottom of the heptafluoropropane gas storage bottle 5. Then the clamping disc 3 and the chassis plate 204 are simultaneously embedded in the installation openings of the middle plate 101, the top plate 102 and the support plate 1. The return spring 202 will push the clamping block 203 of the sliding plate 201 to be embedded in the connecting opening of the connecting strip 301 to limit and fix the clamping disc 3 and the chassis plate 204, thereby realizing the rapid replacement and maintenance of the heptafluoropropane gas storage bottle 5, and replacing and repairing the heptafluoropropane gas storage bottle 5 is easier.

[0026] Example 2: Example 2 differs from Example 1 in that, in this example, the fixing plate 401 is symmetrically arranged around the longitudinal center axis of the clamping disk 3, and the outer wall of the bidirectional screw 4 is connected to the upper inner wall of the fixing plate 401 by a thread;

[0027] The left and right ends of the chassis plate 204 are both opened to form hidden grooves, and the fixing plate 401 is just embedded in the hidden grooves. The fixing plate 401 slides left and right in the hidden grooves. An anti-slip strip is provided on one end of the fixing plate 401 close to the middle of the chassis plate 204;

[0028] By turning the bidirectional screw 4, the bidirectional screw 4 drives the fixing plate 401 to move left and right in the clamping disc 3 to achieve the locking and unlocking operation of the heptafluoropropane gas storage bottle 5. After being locked, the heptafluoropropane gas storage bottle 5 will not shake in the clamping disc 3, which has a better protection and fixing effect on the heptafluoropropane gas storage bottle 5 and is more convenient to use.

[0029] When replacing and repairing the HFC-227ea gas storage bottle between the clamping disc 3 and the chassis plate 204, the clamping disc 3 can support and limit the HFC-227ea gas storage bottle to prevent the HFC-227ea gas storage bottle from being damaged by direct contact and friction with the ground.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
